Deep dive into SharePoint data recovery: HOT SPOTS
Microsoft's popular collaboration application presents unique backup/recovery challenges, especially when it comes to protecting the data in a way that permits granular recovery.
| Collaboration app presents unique backup/recovery challenges, especially when it comes to granular recovery.
microsoft office sharepoint server is becoming a popular enterprise application as companies seek to enhance collaboration across enterprises. But an increased dependence on the platform means it's crucial to establish and maintain business continuity and disaster recovery (DR) strategies.
ESG research finds that 36% of SharePoint users believe their backup processes don't provide an adequate level of protection. And 36% say a SharePoint downtime of 60 minutes or less would have an adverse affect on their business. SharePoint (a collective reference to Microsoft Office SharePoint Server, SharePoint Portal Server and Windows SharePoint Services) is a Web-enabled collaboration platform and central repository for unstructured and semi-structured content. It enables file sharing, document workflow and publishing automation, document management with version control, and search and access control for distributed users. The amount of data stored in SharePoint can be staggering. Native backup and recovery tools are inadequate, and item-level recovery can be a challenge.
In its simplest form, SharePoint can be configured for all services to run on a single server. A popular SharePoint deployment might consist of a small three-tier server farm with a data tier consisting of back-end SQL Server databases where all of the content is stored, a Web tier to deliver content to users, and an app tier hosting background services and apps. Additionally, data related to the farm and its components resides in the configuration database (one per farm). Depending on factors such as implementation size and availability requirements, the deployment scenario selected could translate to a distributed farm configuration.
There are multiple components to each tier that need to be protected. Although the bulk of SharePoint information resides in a SQL database, there are additional files that should be backed up to fully protect a SharePoint environment, including Internet Information Services (IIS) meta data, front-end data, search indexes and customizations. It's best to protect all of these components in a federated way.
SharePoint has two features to guard against accidental deletion of data: version history and a recycle bin. SharePoint's recycle bin has an additional safety net in the form of an administrator-accessible Site Collection Recycle Bin. Unfortunately, versioning and the recycle bin don't address other types of data loss, such as errors or corruption. Also, if an entire document library is deleted, the entire library must be restored. These are two big themes with SharePoint backup and recovery: SharePoint is an application that's challenging to back up and, even when that's successful, recovery of any site data at a granular level is an ordeal. Here's an overview of ways to protect SharePoint content.
SharePoint offers another native tool for backup and restore, the Central Administration user interface. On the plus side, this approach lets the backup be performed for the whole farm down to the content database (with recovery offered at the same level of backup) and provides a choice of full or differential schemes. The downside is that scheduling backup jobs isn't possible and retention management is a manual process.
SQL Server backup: Another popular approach to protecting SharePoint content is to simply perform SQL Server backups. Unfortunately, this approach will leave some SharePoint components unprotected, including IIS meta data, Web front-end data and search indexes. Having a SQL backup ensures full fidelity restore of the database and its content. But these need to be completed with backups from the file system to recover the whole farm in a DR situation. It's important to note that a SQL backup doesn't help with restoring individual items. You'll have to restore the SQL database with a different name, attach it to another farm and restore items to production. This approach may only be suitable for larger sites that have SQL Server tools and a database administrator.
Commercial solutions: Third-party backup and recovery software is another way to go, especially to address the limitations in the native utilities and SQL backup method. Many third-party backup vendors offer some capability for protecting SharePoint, either through a dedicated module for SharePoint backup or a SharePoint app-specific agent that works in conjunction with the backup engine. A backup app can handle the database and system-level protection required of the various SharePoint components. These solutions will deliver automation and customization of backups with features like full, incremental and differential strategies; compression; encryption; direct and indirect restore; retention policies; and expired data clean-up. And many of the backup platforms offer capabilities for creating offsite copies through replication or tape creation.
The most glaring omission for many backup vendors' solutions is granular recovery. To date, only a handful of products offer item-level recovery that doesn't involve a two-step recovery process. These solutions come from a number of vendors, including AvePoint, CommVault, IBM, NetApp and Symantec. Others may redirect the recovery and create a duplicate copy, which will require more storage capacity and necessitate the manual movement of content between duplicate and original sites.
SharePoint usage will likely continue to grow. As the amount and value of data stored on this platform rises, implications for backup and recovery become critical. Taking recovery time and recovery point objectives for SharePoint data into account, it's likely that the top criteria for selecting SharePoint backup will be full fidelity protection, automation, and the ability to recover at site, sub-site and item levels.

NEW YORK — Actress Lindsay Lohan was arrested Thursday in New York City after police said she hit a woman during an argument, then hours later was charged in California with lying to police and reckless driving for a June crash in which her Porsche slammed into a dump truck.
The "Mean Girls" and "Freaky Friday" star was arrested at 4 a.m. and charged with third-degree assault.
She left a police precinct nearly four hours later with a black jacket pulled over her head. Lohan was wearing leggings, a green mini dress and high-heels. She drove off in a black SUV with a driver, a woman and another man who was seen going in and out of the precinct.
Lohan, 26, allegedly got into the spat with another woman at Club Avenue, in Manhattan's Chelsea section. She struck the woman in the face with her hand, police said. The woman did not require medical attention.
Lohan's attorney, Shawn Holley, did not immediately return messages seeking comment.
The charges come just after Lohan's portrayal of Elizabeth Taylor in the Lifetime movie "Liz & Dick" premiered to harsh reviews from critics and the public.
After the June crash, the actress told police her assistant was driving, but detectives determined Lohan was behind the wheel, police said. Prosecutors charged her with three misdemeanors: providing false information to police, reckless driving and willfully obstructing a police officer from their duties. No date for Lohan's arraignment was announced, but the charges are likely to trigger a probation violation for a 2011 necklace theft case.
Lohan's newest arrest is her latest brush with law enforcement in New York City.
She was involved in a New York Police Department investigation in September after alleging a man had assaulted her in a New York hotel, but charges against the man were later dropped.
Also in September, the actress was accused of clipping a man with her car outside another Manhattan nightclub, but prosecutors chose not to move ahead with charges.
In October, police were called to her childhood home on Long Island after a report of a fight between her and her mother. An investigation revealed "no criminality."
The Los Angeles case comes nearly six months after the actress crashed while on her way to a movie set. She was taken to the hospital but returned to the set of the film "Liz and Dick" hours later.
Lohan has become more of a tabloid and courthouse mainstay in recent years than an actress, and her crash while on the way to the set of "Liz and Dick" demonstrated the risk of casting her in films. A week after the accident, paramedics were summoned to Lohan's hotel room in an episode her publicist attributed to exhaustion and dehydration, and shooting on the film was again briefly delayed.
In May, she was cleared of allegations that she struck a Hollywood nightclub manager with her car.
She recently filmed "The Canyons," an indie film written by "Less Than Zero" and "American Psycho" author Bret Easton Ellis.

TOKYO (AP) — In their first meeting since Japan created a new, more independent nuclear agency 13 months ago, the top regulator urged the head of the utility that runs the crippled Fukushima power plant on Monday to take "drastic steps" to mitigate a spate of mishaps at the complex.
Nuclear Regulation Authority Chairman Shunichi Tanaka summoned Tokyo Electric Power Co. President Naomi Hirose to his office to express concerns about growing problems at the plant, including human errors that have led to a series of leaks of contaminated water used to cool the damaged reactors.
Human mistakes are mostly to blame for the recent mishaps, as workers deal with a string of crises. Tanaka said earlier this month the repeated "silly mistakes" are a sign of declining morale and sense of responsibility.
TEPCO acknowledged a systemic problem in a recent report, saying workers under tight deadlines tend to cut corners, making mistakes more likely, and at times don't fully understand their assignments or procedures.
Hirose acknowledged that TEPCO is having trouble finding a stable pool of workers at the plant, but promised to send more staff from other sites to Fukushima, where three reactors melted after a March 2011 earthquake and tsunami. TEPCO has acknowledged that more than 700 employees have left the company in the last year alone.
Later Monday, TEPCO Vice President Zengo Aizawa said the company sees no problem in obtaining enough workers over the next two to three years, but that uncertainty remains over the long-term decommissioning process.
"We are not sure about our long-term staffing situation during the upcoming process of debris removal, which requires different skills," Aizawa told a news conference. Asked if the company may have to consider hiring foreign workers, he said TEPCO is open to that idea even though it's not an immediate option.
It was the first time that Tanaka has met with a utility president, in part because of his attempt to counter criticism that the previous nuclear regulator, which was under the wing of the trade and industry ministry, was too close to the utility sector.
Such criticism contributed to the creation last year of a separate, independent nuclear regulator that Tanaka now heads.
Agency officials said the meeting indicated Tanaka's grave concerns. Tanaka and other commissioners have said they plan to step forward to provide more proactive instructions in the future.
Tanaka told Hirose that resolving the problems requires "drastic steps" with a long-term vision, not procedural changes as TEPCO has suggested, Katsuhiko Ikeda, administrative head of the agency, told reporters after the talks, which he attended. The meeting was closed except for a few minutes at the beginning.
Masashi Goto, a nuclear reactor engineer and lecturer at Meiji University, was skeptical about how effective the meeting would be.
"What matters is what they really talked about," he said. "To me, it seems the regulatory side was just trying to smooth things out and make it look like the situation should start improving."
Tanaka also urged the plant to do more to reduce radioactivity at the site to allow workers to work without full-face masks, which reduce communication and contribute to hard working conditions. He said the company also needs to put enough funds into essential projects.
Hirose acknowledged that TEPCO has been cutting costs and that the precarious state of the plant has contributed to the deterioration of the plant's operations.

Attempt at this. SBI & Heath, feel free to edit if there's anything else you want to add.
The concept
Like many other games on the site (see CW XI, CW Football, etc.) you attempt to make it a professional athlete, this time in in the world of tennis. You sign up here with a short profile and your choice of specialist court, then play tournaments all around the world. In addition to the current roster of CW players, there are also fictional players from all over the world added, and if you like you can try to create rivalries with both the fictional and the real players. (The real tend to be more fun as they talk back, but hey, your choice.)
Playing tournaments
A calendar will be posted at the start of the year, and in each week's thread the tournaments will be listed, so you can indicate where you want to play. Depending on your ranking and the other players' ranking, you will be entered directly into the main draw, the qualifying, or not accepted at all. Sir Bloody Idiot, who runs this thing, may also ask for a schedule 6-8 weeks in advance, to make it easier for him to plan.
The CW Tennis calendar is a simplified model of the real world. There are not quite as many tournaments and professional players as in real life, as simming tournaments for a lot of Swedes ranked #600 is dull. However, the main tournaments:
Grand Slams: These should be familiar. 128 players in each, first to three sets wins the match, winning one sets you apart from the journeymen, winning ten makes you liable to be called almost as good as Rod Laver, winning twenty makes you GOAT. Maa.
The four of them are: Australian Open (January), French Open (May-June), Wimbledon (June-July), CW Open (September). You will probably notice that the US Open has been moved to the tennis complex in Nixonstown, CWLand, as we're one of the strongest tennis economies in the game.
The other big tournaments are:
World Tour Finals: end-of-year tournament with the eight best players in the world by ranking. Most players are tired by this point of the season and treat it as a bit of a hit-about. Held in New York as compensation for robbing them of the US Open.
Nine Masters tournaments: these carry half the ranking points of Grand Slams, and have about half the entry field (except for two early tournaments in the US with 96 players). Most of them are in March through May determining seeds for the three big slams, with a few sprinkled towards the end of the year. All matches to three sets.
Davis Cup: the team competition. Two players from each team play each other in singles (so that's four matches) + one doubles match. First to three sets wins a match, first to three matches goes through to the next round.
250/500 tournaments: in the weeks without big tournaments, the players travel separate ways and play in backwaters such as Båstad, Estoril, 's-Hertogenbosch, Newport and Brisbane. These tournaments are often where lowly ranked players first make their mark; however, if your ranking isn't high enough you may have to qualify, or play in
Challenger tournaments: these are held at even smaller backwaters, carry even less money and even fewer ranking points, but are a necessary starting point. There aren't quite as many of these as in real life, but hopefully enough to keep interest going.
CWLand Championship: national tournament at the end of the season. Only CWers play, the format depends on how many players we have.
Clay: Slow surface - the ball doesn't sit up as much as on the other courts, largely negating the service and winners in favour of players who keep the ball in the court. The French Open and three Masters events are on clay. Not common in CWLand, though we have a few specialists.
Hard court: Rumoured to give the "best mix" between service and baseline play (usually by people from countries where hard court is predominant), it is possible to be successful with both styles. There are many different types of hard courts, and the indoor courts tend to be faster and with more bounce, but for the purposes of the game they are mostly treated as the same. The Australian Open, the CW Open, and six Masters events (possibly subject to change) are on hard court.
Grass court: A fast court without the bounce of hard courts, it makes the service rather important, as aces are more common, along with bad bounces which can force an early end to the point. Specialist grass court players are rather rare, and usually find some form on hard court as well. They often struggle on clay due to different movement and the lesser importance of the serve. The Championships at Wimbledon are played on a grass court.
Ranking points are awarded on a "rolling year-to-date" basis, meaning that points scored in the last 52 weeks counts towards the ranking. In effect, your week-to-week ranking change is thus how many points you improved over that week's performance last year. This makes the week-to-week changes rather incomprehensible (two players who both made the third round may go in opposite directions on the rankings), but does tend to give a balanced ranking overall.
Only your 18 best performances count, of those 18: the 4 Grand Slams and 9 Masters are mandatory. That means that you can only count 5 of the other PTAs/challengers. If you weren't allowed to play the Slams or Masters, you can count other tournaments. (This rule may be changed for next season. Stay tuned.)
There are fewer injuries than in real life, but it's still a part of the sim; so yes, you may be out of the game for some periods.
There's a separate doubles circuit as well, with many successful CW players. Most CW players have a fixed pairing, either with a fictional player or another CW player. The tournaments are mostly the same, but there's separate rankings for it, and you can play doubles and singles in the same week.

I loves Okra with sambal or it's called Lady's Finger in Asia. Since I love Okra so much, I sowed some Okra's seeds in my vegetables garden. While waiting for my Okra plants to grow,I bought some Okra from Indian store nearby.Well,you must wonder why I bought my okra at Indian store not local market,right? Our local market do carry okra but at higher price than Indian store,so instead of $3.99 a pound I can get a pound for $1.99!! Furthermore ,the India store let's me choose and pick the okra.I prefer younger okra for stir-fry..This dish is a very common okra dish in Malaysia ..Ask any Malaysia,if they love okra, I'm sure they love this stir-fry Okra with sambal and dried shrimp.Ingredients:
2 lbs okra,cut both end ,wash and drained
1 small carrot,peel and sliced
4 tbsp dried shrimp,washed and chopped or pound fine
3 tbsp sambal-tumis-sauteed-chili-paste
1 tbsp tamarind powder
2 tbsp sugar
1 tbsp chicken bouillon powder
2 tbsp oil
1: Cut and wash okra,then microwave for high 2 minutes.
2:Heat skillet/pan at medium heat with oil,add in pounded dried shrimp,fry dried shrimp until fragrant.Then add in sambal-tumis-sauteed-chili-paste ,carrot and pre-cooked okra.
3: Stir-fry okra at high heat,add in tamarind powder,sugar and chicken bouillon powder ,stri-fry for 1-2 minutes.Check the seasoning.If you want more spicy and extra sauce/gravy ,add in more sambal and 2 tbsp water.
4:Dish out and serve warm immediately.

HUNTINGTON BEACH, Calif. (KTLA) — Those popular fire pits on the sand on many Southern California beaches may soon be a thing of the past.
The South Coast Air Quality Management District is considering a ban on the fire rings, as two Orange County cities square off over the issue.
Huntington Beach officials say that nearly 12 million people visit state parks in the county, and it generates about $19 million in revenue.
They argue that banning bonfires would cut that revenue in half.
Huntington Beach officials also say the city would lose $1 million in parking revenue alone.
But on the other side of the issue, the Newport Beach City Council says they want to ban the fire pits.
They say that residents along the strand are complaining about the pollution, the smell and some of the rowdy visitors that the bonfires bring.
But other residents are sounding off against the ban.
Thousands of residents of both Huntington and Newport have signed a petition online saying they want to keep the bonfires.
They say the fire rings are a California tradition, and they're a big part of why people come to visit the beaches.
Air quality regulators seem to be backing Newport Beach. One board member says all bonfires should be banned from L.A. to Orange County beaches.
However, no numbers have been given as to the exact impact of the pollution, and that's what the California Coastal Commission wants to hear.
Both sides will present their arguments at a hearing Thursday morning at the AQMD headquarters in Diamond Bar. A decision could come as early as May 3.

Backup best practices are always evolving
Some new advances in backup, such as virtual tape libraries, represent evolutionary enhancements to the traditional backup process, while others like continuous data protection and single-instance storage are potentially far more transformational.
Backup best practices are always evolving
Backup technology doesn't stand still, so the preferred methods for running an efficient backup environment must also adapt.
After four years of writing this column, I'm struck by how much has changed--and how much has remained the same--in backup and recovery. The first column I wrote discussed the do's and don'ts of tape library selection, which is still a relevant topic but not necessarily the kind of material a topical publication would focus on. Since then, new technologies have emerged and backup seems to have been examined from every conceivable angle.
The foundation for the most important changes in backup technology can be summed up in a single word: disk. Low-cost, high-capacity disk storage has become the enabler for a variety of technologies that are redefining backup operations. Some of these advances, such as virtual tape libraries (VTLs), represent evolutionary enhancements to the traditional backup process, while others like continuous data protection and single-instance storage are potentially far more transformational.
Nondisk technologies have also had an impact on how we architect backup solutions. These include dramatic increases in tape capacity and speed, more widespread availability of low-cost network bandwidth, and server technologies such as virtualization.
Backup and recovery best practices continue to evolve. Data capacity demands, recovery expectations, and new application and business requirements all have a bearing on how we manage data protection. Toss in the new technology options, and it's worth re-examining some of our considerations for best practices.
Disk changes everything
Incorporating disk into the backup environment seems to be every backup administrator's goal, but the best method to accomplish this is subject to debate. The options for adding disk to backup were initially limited to the rudimentary support included with backup software products. Aside from IBM Tivoli Storage Manager (TSM), which was designed around the paradigm of a disk-based storage cache, most backup products lacked optimized support for disk. This made the concept of VTLs a particularly attractive way to incorporate disk into the environment.
However, backup software vendors have scrambled to enhance the level of disk support in their products. Newer options, like EMC's NetWorker DiskBackup Option, handle disk like the random-access device it is and provide multiple, concurrent access and improved performance. In Veritas NetBackup 6.0, Symantec has added features like disk watermarks to better support the TSM-like, disk-as-cache model.
In the NAS arena, the tighter integration of Veritas NetBackup with Network Appliance has yielded more advanced disk backup capabilities like the Veritas NetBackup NAS SnapVault Option, which essentially provides long-needed integration between backup and NAS snapshot management. Not to be outdone, EMC's NetWorker offers a NAS PowerSnap Option and extends its NDMP agent to support disk as a target device. Because the use of snapshots and split mirrors has long been a popular method of creating images to be backed up, being able to control and manage that functionality through the backup application is highly desirable and reinforces this approach as a best practice.
For most organizations, VTLs are the most straightforward and least disruptive option for incorporating disk into backup. And we now have enough collective experience to begin to suggest VTL best practices, including some that contradict traditional tape-only practices.
With traditional backups, it was considered extremely risky to extend the period between full backups. With disk, there's no such concern, and doing fewer full backups actually extends the capacity of the VTL, which means potentially retaining more versions of data on disk.
In the IBM TSM world, the disk storage cache was traditionally sized to accommodate at least one night of incremental backups that would later be migrated to tape. The idea was to avoid frequent disk-to-tape migrations that would slow the backup process. With VTLs, TSM still benefits from having a disk storage cache, but the sizing rule no longer applies. The cache can now be a fraction of the size and migrations to the VTL aren't a concern in most cases.
Stop the tape
Despite the attractiveness of disk, organizations with sizeable quantities of data still depend on tape. New generations of tape technology are appearing more frequently but, ironically, the speed and capacity increases aren't always good news. Replacing older technology with new high-performance drives raises expectations of dramatic improvements. In practice, the opposite is often the case.
Tape is a serial technology, so it needs a steady stream of data to maintain its performance. If the data stream can't keep up, performance drops dramatically as the tape drive stops, waits for data, backs up, writes, stops again, etc. This shoe-shining effect also reduces tape drive and media life.
Often, performance problems attributed to "slow tape drives" are actually caused by bottlenecks elsewhere in the data path, and introducing even faster drives actually exacerbates the problem. To improve performance, more data has to be written to fewer drives; for most backup apps this means increasing multiplexing settings.
Does this make multiplexing a best practice? No. Multiplexing is a tradeoff--it may improve backup time, but it degrades restore time. Multiplexing may be a "necessary" practice to deal with the limitations of a given technology in a particular environment, but it's not the preferred way to deal with the problem. A preferred approach is to identify and analyze performance bottlenecks, and to address them where possible. If needed, disk may be introduced as a staging device to keep tape streaming, but data from multiple sources doesn't need to be interleaved via multiplexing.
The virtual environment
Backup best practices are also affected by what's backed up. The widespread adoption of virtualized servers has significantly changed the server world. Virtualized environments, such as those supported by VMware, impact backup.
Backing up a virtualized server can be identical to backing up a physical server. It's possible to install backup client software and perform a traditional backup across the network. But what if 20 virtual servers reside on one physical server and they all try to back up at the same time? This can be a significant load-balancing concern, not to mention having to buy 20 client licenses for a single physical server.
It's also possible to back up a virtual machine as a single disk image. On a VMware ESX Server, each virtual machine exists as a file that can be backed up. It's therefore possible to back up all virtual servers as part of a physical server backup.
Individual virtual server backups allow for easy restore of files for normal operational restores, while image backups enable fast restores of an entire system for DR or migration purposes. It should be noted that in addition to backing up the individual virtual machines, the Linux-based VMware service console must also be backed up.
From a software perspective, the major backup apps provide support for a backup client running on a VMware virtual machine and on the service console, but it's critical to validate the appropriate version. If support for specific app agents is required, check with your backup software vendor to ensure compatibility.
Managing virtual machine backups on a multitude of physical machines can become complex. To address this, VMware Consolidated Backup was introduced with VMware Infrastructure 3. This product centralizes management of VMware backups, and supports quiescing of a virtual machine in addition to integrated snapshotting to a backup proxy server where both file-level and image backups can be performed. It provides much of its functionality through pre- and post-processing scripts that can be executed in conjunction with standard third-party backup client software.
Given the adoption rate of virtual servers, it's reasonable to expect further enhancements from existing apps and additional alternative approaches to protecting these environments. So, at this stage, best practices are still evolving.
Regardless of the technology selected, the fundamentals still apply when it comes to backup best practices: Policy, process and metrics are the keys to ensuring successful and recoverable backups.

Saturday afternoon the man who gave us "Dump That Chump," "My Next Ex-Wife," "Money Must Think I'm Dead," and of course, "That's Big" will be performing, with the Nightcats, at the 19th annual North River Blues Festival at the Marshfield Fair, taking the stage at 5:30 p.m. Saturday.
Estrin fronted Little Charlie & the Nightcats for 33 years, before guitarist Charlie Baty stepped away from the road in 2008. Of course, many fans had always assumed the stylish singer/harmonica wizard in the pompadour hair and pencil-thin mustache was Little Charlie, but the band had always been led by the more effacing guitarist. After some trepidation, Estrin took over the lead role, and the quartet replaced Baty with a young Norwegian firebrand named Kid Andersen.
While Baty's style owed much to the West Coast, more swinging style of blues, Andersen comes from more of a blues-with-rock direction, citing Otis Rush and B.B. King as major inspirations. But Andersen is also likely to inject unexpected treats like surf-rock figures into his solos, too. Ironically, local fans can compare the two guitar styles Saturday, as Baty is doing some limited touring this summer with the Golden State Lone Star Revue, which follows the Nightcats with the night's final set.
Earlier this summer – July 8 to be exact– Estrin & the Nightcats released "You Asked For It ... Live!" a baker's dozen of songs recorded at the San Francisco club Biscuits & Blues last October. It had been quite a while since the band did a live CD, and the new album is an attempt to collect a bunch of fan favorites – many of them a decade or more old – with the fresh new arrangements they get today. Signature tunes like "My Next Ex-Wife," "Smart Like Einstein," and "That's Big" are there, but also some chestnuts the band hadn't done as regularly, but which they thought deserved revivals.
"There were some songs we knew had to go on there, because people ask for them all the time," said Estrin, from his Sacramento area home earlier this month. "And others were on our best-selling CDs. Obviously tunes like "Dump That Chump" and "That's Big" had to be on the live record. But even with those, these songs have evolved, so these are really different versions from the way they were originally recorded.
"Then, there were some other songs that maybe we didn't play that often on tour," added Estrin. "But we had found a different way of doing them, a new approach that we wanted to share. The only new song on the live album is "Baker Man Blues," written by our drummer J. Hansen, and it's a nice change of pace."
While Baty and Estrin had toured the world together for better than three decades, their rhythm sections changed over time. But this particular foursome has been pretty solid, and that longevity together makes the Nightcats an extremely tight unit.
"There is definitely a kind of band synergy that occurs when you have been with someone for a long time," said Estrin. "Kid has been with us for six years now, J. Hansen for 12 years, and bassist Lorenzo Farrell for 11 years. Having that kind of experience together makes a big difference – no matter how good a musician you are, if you don't have that telepathy with your band mates, it won't be as good."
Despite their relentless tour schedule, the Nightcats have not encountered Baty on the road like they will be able to on Saturday in Marshfield. Estrin is looking forward to it, and suggested there might well be some jamming between the two bands.
"We played Marshfield once before, when Charlie was still with us, and I remember it was boiling hot," said Estrin. (Our files suggest it was 2002). "I'm excited to see him and hear those guys play – Mark Hummel is with their group and he's one of my favorite harmonica players."
But let's get back to that songwriting. Estrin's most hilarious tune might be "That's Big," his paean to larger women, where he avoids insulting them in any way, yet still presents his appreciation in side-splitting ways. "All that meat, and those potatoes, too!" is the most memorable chorus saluting plus-size female charms.
"I guess I'm a deadline writer," said Estrin, 64. "I usually need the pressure of having to make a record to start writing, and I wish it wasn't that way. I'm lazy, but I'm a perfectionist too, which is a bad combination. I don't enjoy the stress of writing, and it's not a comfortable process for me. There's a lot of anxiety built into it for me, and I'm more grateful when it is done than actually satisfied. You always wonder – 'can I do it again?'"
"But we have some new ones we'll probably play Saturday," added Estrin. "We have two new albums (noting 2012's "One Wrong Turn" studio CD) of material to play from the past couple years, and we'll be delving back into our past catalog, to tunes we did with Little Charlie. We have some new ones we're working on, but we tend not to perform those until we're closer to recording them."
Could we expect some obscure Nightcats chestnuts among the mix?
"There are so many songs we do live, but maybe there will be some that maybe we don't play all the time," Estrin explained. "The band guys occasionally want to resurrect some older ones. 'Thinking With the Wrong Head' and 'Living Hand to Mouth' are a couple of old ones we hadn't done for years, and now we have new arrangements that are working out really well onstage."
Estrin is such a captivating singer, and clever songsmith, it is easy to forget he is one hellacious blues harmonica player. Aficionados know that, which is one reason he won the 2013 Blues Music Award as Best Instrumentalist, Harmonica. With typical modesty, he deflects the plaudits to his band mates.
"It's nice to get recognized by the community of your fellow musicians," Estrin demurred. "But we have been out there doing it for a long time. I have been really lucky, to have been able to work with two of the greatest guys ever, in Little Charlie Baty and Kid Andersen. It's just ridiculous to be that fortunate with guitar players. They're very different, but they both love music and know the blues inside and out. They come from different influences but still both fit me to a 'T'. I'm so lucky to have had the career I've had, and I still love doing it every night on stage."

Dr. Knut Stamnes' Seminal Paper Informs Research in Climate Change, "Greenhouse" Effect
Professor Knut Stamnes of the Stevens Department of Physics and Engineering Physics is renowned for simplifying the process now used to remotely sense the particles in the atmosphere, the microbiological constituents of the ocean, and the composition of sheets of ice and snow. His incisive 1989 article introduced a new mathematical algorithm for the calculation of radiative transfer through layered material, and it continues to be a vital contribution to researchers around the world.
It is particularly valuable to atmospheric research because radiative transfer and energy balance essentially comprise the Earth's climate. If, for example, incoming radiation increases without a subsequent increase in outgoing radiation, the energy balance of our atmosphere is reestablished by an increase in temperature. This is often described as the "greenhouse" effect. By enabling researchers to calculate radiative transfer in the atmosphere, Dr. Stamnes' article helps to study and model the climate.
Applied Optics declares it the most cited article of the journal's 50-year history in its recently released anniversary list.
"Dr. Stamnes' research has proven indispensable for his peers and for researchers across multiple disciplines," says Dr. Michael Bruno, Dean of the Charles V. Schaefer, Jr. School of Engineering and Science. "The Applied Optics anniversary ranking makes the scope of its impact clear."
The pivotal article, titled "Numerically stable algorithm for discrete-ordinate-method radiative transfer in multiple scattering and emitting layered media", has become a benchmark for further innovation in the field of radiative transfer, and Dr. Stamnes uses the algorithm and the principles that underpin it to this day.
Dr. Stamnes and his collaborators Si-Chee Tsay and Warren Wiscombe of NASA, and Kolf Jayaweera of CSU Fullerton made it simple for researchers to determine the composition of a material by measuring how radiation—light, for instance— moves through it. They outlined a mathematical procedure and developed a computer program which allows researchers to calculate the transfer of radiation through a plane-parallel material based on the known optical properties of a system. They can thus measure the distribution of light transmitted through or reflected from a substance and compare observations with their calculations to determine its composition.
The approach has been exceedingly useful, with diverse applications in fields such as the study of aerosols, clouds, the atmosphere, and the climate; astronomy; and the propagation of light in organic tissue.
Because satellites pick up radiation from the earth in a process called passive remote sensing, Dr. Stamnes' algorithm can be applied to study distant and inaccessible areas of the planet. This enables the detection of algal blooms, particles, and dissolved organic matter in the ocean, as well as the examination of radiative properties of snow and ice. Scientists use remote sensing to study the health of the ocean, vegetation rates, erosion, pollution, forestry, weather, and land use.
Dr. Stamnes currently uses the algorithm and its related principles to study the propagation of light in tissue. Light travels through tumors differently than it does through healthy tissue, and a device based on Dr. Stamnes' algorithm would help distinguish the two in a simple and non-invasive manner. This makes for easier and more accurate skin cancer screenings, allowing doctors to detect tumors earlier and thus give treatment the greatest opportunity for success.
"The breadth of applications of Dr. Stamnes' work is remarkable," notes Dr. Rainer Martini, Director of the Department of Physics and Engineering Physics. "It is exhilarating to see the progression from theory and mathematical equations to the climate models cited in news and government policy, or a new screening method at a doctor's office."
Dr. Stamnes feels there is still much work to be done on remote sensing.
"New discoveries and applications have illuminated whole new areas of study within applied optics, and the research is extremely vibrant," he says. "Remote sensing is a particularly competitive field, but with our capabilities Stevens can play a big role in its future."
His research has been funded by the National Science Foundation, the U.S. Department of Energy, National Aeronautics and Space Agency, National Oceanic and Atmospheric Administration, and the Japanese Aerospace Exploration Agency.

LLVM Target Description Files
The "mix and match" approach allows target authors to choose what makes sense for their architecture and permits a large amount of code reuse across different targets. This brings up another challenge: each shared component needs to be able to reason about target specific properties in a generic way. For example, a shared register allocator needs to know the register file of each target and the constraints that exist between instructions and their register operands. LLVM's solution to this is for each target to provide a target description in a declarative domain-specific language (a set of
.td files) processed by the tblgen tool. The (simplified) build process for the x86 target is shown in Figure 5.
Figure 5: Simplified x86 target definition.
The different subsystems supported by the
.td files allow target authors to build up the different pieces of their target. For example, the x86 back end defines a register class that holds all of its 32-bit registers named
GR32 (in the
.td files, target specific definitions are all caps) like this:
def GR32 : RegisterClass<[i32], 32, [EAX, ECX, EDX, ESI, EDI, EBX, EBP, ESP, R8D, R9D, R10D, R11D, R14D, R15D, R12D, R13D]> { … }
This definition says that registers in this class can hold 32-bit integer values (
i32), prefer to be 32-bit aligned, have the specified 16 registers (which are defined elsewhere in the
.td files) and have some more information to specify preferred allocation order and other things. Given this definition, specific instructions can refer to this, using it as an operand. For example, the "complement a 32-bit register" instruction is defined as:
let Constraints = "$src = $dst" in def NOT32r : I<0xF7, MRM2r, (outs GR32:$dst), (ins GR32:$src), "not{l}\t$dst", [(set GR32:$dst, (not GR32:$src))]>;
This definition says that
NOT32r is an instruction (it uses the
I tblgen class), specifies encoding information (
0xF7, MRM2r), specifies that it defines an "output" 32-bit register
$dst and has a 32-bit register "input" named
$src (the GR32 register class defined above defines which registers are valid for the operand), specifies the assembly syntax for the instruction (using the
{} syntax to handle both AT&T and Intel syntax), specifies the effect of the instruction and provides the pattern that it should match on the last line. The
let constraint on the first line tells the register allocator that the input and output register must be allocated to the same physical register.
This definition is a very dense description of the instruction, and the common LLVM code can do a lot with information derived from it (by the
tblgen tool). This one definition is enough for instruction selection to form this instruction by pattern matching on the input IR code for the compiler. It also tells the register allocator how to process it, is enough to encode and decode the instruction to machine code bytes, and is enough to parse and print the instruction in a textual form. These capabilities allow the x86 target to support generating a standalone x86 assembler (which is a drop-in replacement for the "gas" GNU assembler) and disassemblers from the target description as well as handle encoding the instruction for the JIT.
In addition to providing useful functionality, having multiple pieces of information generated from the same "truth" is good for other reasons. This approach makes it almost infeasible for the assembler and disassembler to disagree with each other in either assembly syntax or in the binary encoding. It also makes the target description easily testable: instruction encodings can be unit tested without having to involve the entire code generator.
While we aim to get as much target information as possible into the .td files in a nice declarative form, we still don't have everything. Instead, we require target authors to write some C++ code for various support routines and to implement any target specific passes they might need (like
X86FloatingPoint.cpp, which handles the x87 floating point stack). As LLVM continues to grow new targets, it becomes more and more important to increase the amount of the target that can be expressed in the .td file, and we continue to increase the expressiveness of the .td files to handle this. A great benefit is that it gets easier and easier write targets in LLVM as time goes on.
Interesting Capabilities Provided by a Modular Design
Besides being a generally elegant design, modularity provides clients of the LLVM libraries with several interesting capabilities. These capabilities stem from the fact that LLVM provides functionality, but lets the client decide most of the policies on how to use it.
As mentioned earlier, LLVM IR can be efficiently (de)serialized to/from a binary format known as LLVM bitcode. Since LLVM IR is self-contained, and serialization is a lossless process, we can do part of compilation, save our progress to disk, then continue work at some point in the future. This feature provides a number of interesting capabilities including support for link-time and install-time optimization, both of which delay code generation from "compile time".
Link-Time Optimization (LTO) addresses the problem where the compiler traditionally only sees one translation unit (for example, a
.c file with all its headers) at a time and therefore cannot do optimizations (like inlining) across file boundaries. LLVM compilers like Clang support this with the
-flto or
-O4 command line option. This option instructs the compiler to emit LLVM bitcode to the
.o file instead of writing out a native object file, and delays code generation to link time, shown in Figure 6.
Figure 6: LTO.
Details differ depending on which operating system you're on, but the important bit is that the linker detects that it has LLVM bitcode in the .o files instead of native object files. When it sees this, it reads all the bitcode files into memory, links them together, then runs the LLVM optimizer over the aggregate. Since the optimizer can now see across a much larger portion of the code, it can inline, propagate constants, do more aggressive dead code elimination, and more across file boundaries. While many modern compilers support LTO, most of them (for example, GCC, Open64, the Intel compiler, etc.) do so by having an expensive and slow serialization process. In LLVM, LTO falls out naturally from the design of the system, and works across different source languages (unlike many other compilers) because the IR is truly source language neutral.
Install-time optimization is the idea of delaying code generation even later than link time, all the way to install time, as shown in Figure 7. Install time is a very interesting time (in cases when software is shipped in a box, downloaded, uploaded to a mobile device, etc.), because this is when you find out the specifics of the device you're targeting. In the x86 family for example, there are broad variety of chips and characteristics. By delaying instruction choice, scheduling, and other aspects of code generation, you can pick the best answers for the specific hardware an application ends up running on.
Figure 7: Install-Time Optimization
Compilers are very complicated, and quality is important, therefore testing is critical. For example, after fixing a bug that caused a crash in an optimizer, a regression test should be added to make sure it doesn't happen again. The traditional approach to testing this is to write a .c file (for example) that is run through the compiler, and to have a test harness that verifies that the compiler doesn't crash. This is the approach used by the GCC test suite, for example.
The problem with this approach is that the compiler consists of many different subsystems and even many different passes in the optimizer, all of which have the opportunity to change what the input code looks like by the time it gets to the previously buggy code in question. If something changes in the front end or an earlier optimizer, a test case can easily fail to test what it is supposed to be testing.
By using the textual form of LLVM IR with the modular optimizer, the LLVM test suite has highly focused regression tests that can load LLVM IR from disk, run it through exactly one optimization pass, and verify the expected behavior. Beyond crashing, a more complicated behavioral test wants to verify that an optimization is actually performed. Here is a simple test case that checks to see that the constant propagation pass is working with add instructions:
; RUN: opt < %s -constprop -S | FileCheck %s define i32 @test() { %A = add i32 4, 5 ret i32 %A ; CHECK: @test() ; CHECK: ret i32 9 }
RUN line specifies the command to execute: In this case, the
opt and
FileCheck command line tools. The
opt program is a simple wrapper around the LLVM pass manager, which links in all the standard passes (and can dynamically load plugins containing other passes) and exposes them through to the command line. The
FileCheck tool verifies that its standard input matches a series of
CHECK directives. In this case, this simple test is verifying that the
constprop pass is folding the
add of 4 and 5 into 9.
While this might seem like a really trivial example, this is very difficult to test by writing
.c files: front ends often do constant folding as they parse, so it is very difficult and fragile to write code that makes its way downstream to a constant folding optimization pass. Because we can load LLVM IR as text and send it through the specific optimization pass we're interested in, then dump out the result as another text file, it is really straightforward to test exactly what we want, both for regression and feature tests.
When a bug is found in a compiler or other client of the LLVM libraries, the first step to fixing it is to get a test case that reproduces the problem. Once you have a test case, it is best to minimize it to the smallest example that reproduces the problem, and also narrow it down to the part of LLVM where the problem happens, such as the optimization pass at fault. While you eventually learn how to do this, the process is tedious, manual, and particularly painful for cases where the compiler generates incorrect code but does not crash.
The LLVM BugPoint tool uses the IR serialization and modular design of LLVM to automate this process. For example, given an input
.ll or
.bc file along with a list of optimization passes that causes an optimizer crash, BugPoint reduces the input to a small test case and determines which optimizer is at fault. It then outputs the reduced test case and the
opt command used to reproduce the failure. It finds this by using techniques similar to "delta debugging" to reduce the input and the optimizer pass list. Because it knows the structure of LLVM IR, BugPoint does not waste time generating invalid IR to input to the optimizer, unlike the standard "delta" command line tool.
In the more complex case of a miscompilation, you can specify the input, code generator information, the command line to pass to the executable, and a reference output. BugPoint will first determine if the problem is due to an optimizer or a code generator, and will then repeatedly partition the test case into two pieces: one that is sent into the "known good" component and one that is sent into the "known buggy" component. By iteratively moving more and more code out of the partition that is sent into the known buggy code generator, it reduces the test case.
BugPoint is a very simple tool and has saved countless hours of test case reduction throughout the life of LLVM. No other open source compiler has a similarly powerful tool, because it relies on a well-defined intermediate representation. That said, BugPoint isn't perfect, and would benefit from a rewrite. It dates back to 2002, and is typically only improved when someone has a really tricky bug to track down that the existing tool doesn't handle well. It has grown over time, accreting new features (such as JIT debugging) without a consistent design or owner.
LLVM's modularity wasn't originally designed to directly achieve any of the goals described here. It was a self-defense mechanism: it was obvious that we wouldn't get everything right on the first try. The modular pass pipeline, for example, exists to make it easier to isolate passes so that they can be discarded after being replaced by better implementations (I often say that none of the subsystems in LLVM are really good until they have been rewritten at least once).
Another major aspect of LLVM remaining nimble (and a controversial topic with clients of the libraries) is our willingness to reconsider previous decisions and make widespread changes to APIs without worrying about backwards compatibility. Invasive changes to LLVM IR itself, for example, require updating all of the optimization passes and cause substantial churn to the C++ APIs. We've done this on several occasions, and though it causes pain for clients, it is the right thing to do to maintain rapid forward progress. To make life easier for external clients (and to support bindings for other languages), we provide C wrappers for many popular APIs (which are intended to be extremely stable) and new versions of LLVM aim to continue reading old .ll and .bc files.
Looking forward, we would like to continue making LLVM more modular and easier to subset. For example, the code generator is still too monolithic: It isn't currently possible to subset LLVM based on features. For example, if you'd like to use the JIT, but have no need for inline assembly, exception handling, or debug information generation, it should be possible to build the code generator without linking in support for these features. We are also continuously improving the quality of code generated by the optimizer and code generator, adding IR features to better support new language and target constructs, and adding better support for performing high-level language-specific optimizations in LLVM.
The LLVM project continues to grow and improve in numerous ways. It is really exciting to see the number of different ways that LLVM is being used in other projects and how it keeps turning up in surprising new contexts that its designers never even thought about. The new LLDB debugger is a great example of this: it uses the C/C++/Objective-C parsers from Clang to parse expressions, uses the LLVM JIT to translate these into target code, uses the LLVM disassemblers, and uses LLVM targets to handle calling conventions among other things. Being able to reuse this existing code allows people developing debuggers to focus on writing the debugger logic, instead of reimplementing yet another (marginally correct) C++ parser.
Despite its success so far, there is still a lot left to be done, as well as the ever-present risk that LLVM will become less nimble and more calcified as it ages. While there is no magic answer to this problem, I hope that the continued exposure to new problem domains, a willingness to reevaluate previous decisions, and to redesign and throw away code will help. After all, the goal isn't to be perfect, it is to keep getting better over time.

(I have a BS in information systems management) I've posted mainly in the Taiwan forum as that's where I will be moving eventually. Thoughts, feedback, and questions are welcome. Cheers! If you are looking at Taiwan you might want to look into getting a teachers certificate and state licensing. Without it you are limited to the language academies and it is a hard row to hoe and you will be competing with a bunch of 20-somethings (and the directors are looking for young folks to sing, dance and play with kids). If you DO get it then you are eligible for work in the public school system. The salary is about double what you get in the academies and often include perks such as airfare, housing, medical insurance, etc. .

'All Access Nashville': Taylor Swift Nixes Love Talk, LeAnn Rimes Wrote Affair Songs
The first ladies of country, such as Taylor Swift, Carrie Underwood, LeAnn Rimes, Reba McEntire and Miranda Lambert, were featured on ABC's 'All Access Nashville' hour-long special last night (Oct. 26.) There was some skirting of issues (such as Swift politely declining to discuss her love life) and some big reveals, such as Rimes sharing that she has penned new songs about her headline-grabbing affair with now-husband Eddie Cibrian.
Lambert shared why she likes the cheatin' and drinkin' songs, while Underwood's segment was pre-taped, and she introduced a news package on the genre's most influential women.
Swift, who towered over host Katie Couric, revealed she sometimes records spontaneous melodies on her iPhone. Couric mentioned that with each new Swift hit comes the guessing game. Which famous ex is 'We Are Never Ever Getting Back Together' really about? Was the scarf in the video a hint about the identity of the ex, revealing that it's Jake Gyllenhaal?
"For me the one thing that I keep really close is the identity of who these songs are about," Swift said. She has no problem with fan fiction "written" to fill in the gaps.
When Couric asked if Swift ever hears from exes once they make it into a song, she replied, "They don't say it that gracefully or with that eloquent tone. If they are not liking what's written about them or what they assume is written about them, then I hit the nail on the head. It's probably true."
Couric tried to steer the conversation to Swift's "fun summer," which was obviously a reference to her romance with Conor Kennedy. "It was a great summer. The single came out, I made the album…" Swift said, skirting the issuing in the most ladylike of ways.
She continued, "For me, I think my personal stories sound better in a song than in an interview in quotes. It's not about what gossip is online. I don't read any of that stuff. I have a huge priority on being happy. That's not Googling myself and checking every minute." So, basically, it was not a revelatory chat at all.
Reba, arguably the reigning queen of country, was the subject of a bio package, about never giving up, even when people told her she had peaked.
Nothing was off limits for Rimes, looking hot with tossled hair and thigh-high, black leather boots. She was an open book about why she went to treatment and how people had expressed that they couldn't understand why she was hurting so badly.
"I wasn't a kid," she said through tears. "You get to see your kids be kids. I didn't get any of those things." She bought a house for her family when she was 12, which was a lot of pressure, and robbed her of her sense of identity. "Sometimes I want to go back to the trailer," she mused.
She learned to "be comfortable with me" in treatment. "Not LeAnn Rimes the singer, but LeAnn the human being," she revealed.
She approached her new album 'Spitfire' in a different way. It was not about reaching the high notes but about going through a musical therapy session.
She wrote 'What Have I Done' about her ex-husband Dean Sheremet, who has heard it. She also wrote 'Borrowed' about the headlines from her affair with new husband Cibrian. "I love that man more than anything," she said.
Lambert and the Pistol Annies were featured as the bad girls of country. Lambert talked about throwing back cinnamon whisky shots before taking the stage, with the cheating and drinking songs being what makes Lambert feel better when she is having a bad day.
Underwood appeared at the end, saluting the likes of legends like Patsy Cline, as well as contemporary acts. She essentially walked through all the beloved ladies of the genre.
The special was a love letter to country's finest women.

The man himself, Judd Apatow purchased my artwork from the show! Here's a picture to sort of prove it!
Prints are now available to purchase online by clicking HERE!
Gallery 1988's last group show of 2012 is gonna be a big one. With a year that has seen some incredible shows like The Avengers, Breaking Bad, and Arrested Development, Gallery 1988 is closing out the year with a bang.
Opening Tuesday, December 4th and running until December 30th, Gallery 1988's stable of many artists (including myself) are paying tribute to one of the most prolific comedy writers/producers/directors of all time, the brilliant Judd Apatow. I'm a big fan of Mr. Apatow's work, so it was a huge honor to participate in this show. It was hard to narrow down one movie or show of his to do a piece based off of, so I decided to do almost all of them...
"Apatow Elementary"
There is a private opening that you can attend if you RSVP to Gallery 1988 via e-mail! Just contact the kind folks at firstname.lastname@example.com.
A limited number of my signed prints (13x19) will be available to purchase at the gallery.

Former Senator Rick Santorum doesn't have much of a chance of winning the Republican nomination.
Perhaps that's why he's now pulling out all the stops.
After suggesting that church and state should be combined, blasting Puerto Ricans for speaking Spanish, and promising an anti-porn crusade, Santorum has turned to post-apocalyptic imagery and subliminal advertising.
Witness the "teaser" for a new Santorum video ad series that will soon debut on RickSantorum.com.
It's filled with disturbing images of the dystopian future that supposedly awaits Americans if Obama is reelected.
It has a horror-movie soundtrack.
And it employs subliminal messages.
The latter seem designed to:
1) Confirm the suspicion of many Americans that Obama is a Muslim
2) Suggest that Obama is pleased by and supports the crazy people who run Iran
3) Suggest that Obama is a "sworn enemy of America."
The latter hat-trick is accomplished with some rapid jump-cuts at the 40-second mark of the "Obamaville" teaser.
We've included the full video on the first slide below. Watch that, and then...

Egypt isn't what it appears to be in the media...but that's no real surprise, since not much is. I moved here in the late 80's from Toronto, Canada, with my Canadian/Egyptian husband, my son and my daughter. The children adapted quickly and we decided that this country was a good place to live. Now I wouldn't change my home for anything.

The Second Day on the River
The next morning we had breakfast at Kom Ombo and then set sail for Edu. This was my favourite part of the trip, heading down the Nile with the northwind in our faces. We passed farms much like those of my area, and fishermen working their boats in the river while their children played on sandbars nearby. Mango, orange, and banana orchards lined the river, but the date palms here in the south were not as well-trimmed as those in our neighourhood.
We weren't the only ship on the river. In addition to the fishing skiffs, there were some smaller motor craft for travel or cargo and, of course, other cruise boats. Since we were all supposed to be going through the locks at Esna that evening, sometimes things looked like an old fashioned river boat race. The weather had warmed up quite a bit, but most of us were looking abit askance at some of the travelers on other boats who were sunbathing on the top deck. Maybe our boat was colder on the topdeck or something but we were quite happy in tshirts.
When we got to Edfu we were told that we would take a horse-drawn carriage to the temple and back. To my delight, the majority of the horses presenting themselves to us at the riverside were in excellent condition. As a horse owner and someone who works with horses, I really can't tolerate working abused horses. The Brooke Hospital group have been working really hard in Upper Egypt constructing shades where the horses can rest and visiting veterinary services.
The temple at Edfu is amazing. It is wonderfully preserved temple that was constructed for the most part during Greco-Roman times and was buried in sand until the 1800's. I remember being incredibly impressed with its halls and decoration years ago. Many of the halls are stained with soot near the ceilings from people taking shelter in them many centuries ago.
After Edfu, we set sail once again, heading for the locks at Esna. At times we could see desert on one side or another, and there were some beautiful buildings along the river. One sand coloured house in the traditional Nubian style particularly caught my eye. The way that it blended into the surrounding desert hills was lovely.
Finally, as the sun was setting, we came to Esna where we moored with a number of other boats while waiting our turn to pass through the locks. South of Esna the river is significantly higher than it is below Esna. Nile cruisers traveling south from Luxor wait in pairs to enter the lock, have about 4 metres of water pumped in to raise them to the southern level, and then after the southbound boats leave the lock, the northbound boats, like ours, enter to have the lock pumped out to lower us to the northern level. From Esna we traveled north to Luxor to find ourselves moored at the corniche in Luxor the next morning.

New SKF super-precision cylindrical roller bearings series on show at EMO Milano 2015
2015 October 06, 13:00 CEST
SKF is launching two new super-precision cylindrical roller bearings series, which meet the machine tool industry's demand for higher speed capability with low friction. The new bearings will be shown for the first time at EMO Milano 2015
Gothenburg, Sweden, 6 October 2015: SKF, the knowledge engineering company, is launching two new SKF super-precision cylindrical roller bearings series at EMO Milano 2015. Both of these new series deliver superior bearing performance compared with existing SKF offerings, accommodating higher speeds and lower friction as well as providing a variety of other operational benefits to the machine tool industry.
Mauro Merlo, SKF Super Precision Bearings Product Manager at SKF, explains, "The new SKF super-precision cylindrical roller bearings are optimized solutions for OEMs that require greater load carrying capacity and higher speeds. While the SKF super-precision single row cylindrical roller bearings have a higher speed capability, the SKF super-precision double row cylindrical bearing are more suitable for heavier loads. Visitors to EMO Milano 2015 will get an exclusive first look at both of these new series, which will be available for order in 2016."
The single row cylindrical roller bearings series is equipped with an outer ring centered cage, window-type, made of carbon fiber reinforced polyetheretherketone (PEEK). The reduced number of rollers, together with the optimized cage, enable the bearings to accommodate higher speed, attain lower operating temperature and lower friction. The range is suited for use where shaft diameters range from 40 to 80 mm.
The new single row series represents the optimal solution for applications like the non-tool end of a motorized spindle, where the requirement for higher speed outweighs that for higher rigidity, high-speed milling machines, high-speed machining centres, lathe electro-spindles.
The new double row super-precision cylindrical roller bearings series provides a unique balance between load carrying capacity, rigidity and speed. This series allows higher speed capability in conventional high stiffness belt-driven CNC lathe spindle. It features three integral flanges on the inner ring and no flanges on the outer ring. In addition, the series has an optimized internal geometry and a new glass fiber reinforced, prong-type, roller centered PEEK cage, which enables the bearings to accommodate higher speeds and minimize the amount of frictional heat generated. The range is ideal for shaft diameters from 25 to 130 mm.
SKF possesses extensive experience of specifying bearings for specific applications. The company will utilize its advanced knowledge of the machine tool sector to support OEMs to evaluate the total cost of ownership and benefits of the new SKF super-precision series, ensuring the correct bearings are specified for the application.
EMO Milano 2015 takes place on 5-10 October 2015 in Milan, Italy. Visitors to the event will find SKF in Hall 3 at Stand L15-H16.

Most small businesses don't have the ability or resources to have IT professionals on staff, and instead rely on outside IT specialists to help them maintain their communications, troubleshoot computer issues, and support networks and infrastructure. These individuals are indispensable to keeping your business up and running, as well as helping to facilitate growth. They are also the go-to people for making technology purchases and often act in an advisory role for their customers and clients. The bottom line is that they are important to you and your business!
No one knows just how important they are – or champions their cause more – than Harry Brelsford, founder of SMB Nation, a publishing and events company targeted at the small and medium-sized business (SMB) channel partner/reseller/consulting/VAR community. SMB Nation spreads the knowledge of SMB technology trends through its conferences, books, SMB PC magazine, online services, worldwide seminars, workshops, and accredited Pocket MBA certificate (an academic partnership with Aspen University).
Harry joins me today to chat about IT involvement with small and medium-sized businesses, as well as the Top 150 SMB program currently underway.
BIZ BLOG: Hi Harry, thanks for joining me. Can you share some insights about the role that IT companies play in the life of a small business?
HB: Perhaps the worst kept secret in the new economy is the dominant role that technology plays. At home and work, you can't escape it. Central to making technology "work" at work, the independent IT company makes it all happen. Affectionately known as the computer guy/gal, this individual becomes a trusted advisor, integrated into the fabric of the small business. She offers insights such as the secure deployment of smartphones and tablets into the small business.
Do you have some tips to pass along to help small businesses choose the right IT professional/company to handle the tech issues that arise in their day to day operation?
Personally what I've found is that a small business should (hopefully) be served by a small business. It's about right-sizing. A small IT support company best knows the needs, hopes and desires of a small business. Selection is a process you need to honor and in my opinion, it starts with a referral – ask another small business if they are pleased with its IT services.
Would you look for a different IT consultant to help with your mobile needs than you would for other technology needs?
It depends. If the need is that of a smaller business, it's likely that the single point of contact – the computer guy – can handle it. If it's more sophisticated, such as the BlackBerry® Enterprise Server (BES), then you need to strongly consider a specialist.
Tell us about the SMB 150 and why it's important to acknowledge the work of these organizations in your community.
There are both known and unknown SMB heroes out there that need and deserve recognition. The SMB 150 awardees are influencers who set the tone and tenor of the best practices in SMB technology, plus best behaviors. We acknowledge that these heroes need 15 minutes of fame; the SMB 150 awards support that goal.
Don't forget to head over to www.smb150.com to check out the SMB 150 program, and to vote! Watch for more discussion on our @BlackBerry4Biz Twitter® channel.
Calling all SMB owners for discussion: How did you choose your IT support? Share in the comments below!

Four years ago, I, together with thousands of other people, went to Invesco Field to listen to Barack Obama accept the Democratic Party's nomination for president of the United States. Indeed, it was a historic moment and I wanted to be part of it. I admit to have been swept up, to a small extent, in Obamamania. I believed that the very fact that a person such as Barack Obama could become president would give the average American hope and inspiration – something that was much needed during those tough economic times.
In his acceptance speach this year we saw a chastened President Obama. After all the lofty promises he made in 2008, he has come face to face over the last four years with the harsh reality of what is possible. Yet he continues to say that he can change it all, all he needs is more time. It seems that he has not learned the most important lesson of all — human limitation.
In fact, the Torah warns us against saying: "My power and the strength of my hand created this success" (Deuteronomy 8:17). Acknowledgement must go to a power higher.
There is a biblical law stating that that, upon settling in the Land of Israel, the Israelites were commanded: Take of the first fruit to bud on a tree and put them into a basket and bring it to the House of God (Deuteronomy 26:1-2). The idea here is that although the fruit came about through the work of the farmer, divine help is also a part of the equation. This is acknowledged through bringing the first fruit to the Temple in Jerusalem.
