Back cover copy
Unique coverage of traditional database theory and current research for building easier-to-mange distributed database systems A distributed database management system (DDBMS) is a layer of software, implemented on top of existing database management systems, allowing users transparent access to information dispersed across a network. This book addresses the architectural and platform issues on the design and development of a DDBMS, guiding readers in building their own systems in real-world environments. "Distributed Database Management Systems" is divided into three units. The first provides a theoretical foundation for understanding the internal processing of the DDBMS available to address these issues. The second unit presents the "state of the practice," examining the architectural alternatives that practitioners will likely encounter in the real world and the exploring the general requirements for any platform capable of implementing a DDBMS architectural alternative--including those yet to be invented. The final unit focuses on distributed database implementation, examining three platforms suitable for the development of a real DDBMS system--the Java Message Service (JMS), the Java 2 Enterprise Edition (J2EE), and the Microsoft .NET Framework. For each, a "starter kit" is provided (containing a detailed overview and an extensible framework) and discussed in detail.show more

Beloved Inner-West drinking hole (and Time Out's Pub of the Year) the Courthouse Hotel (more affectionately known as the Courty) has teamed up with Sydney Dogs and Cats Home to hold a fundraiser for our favourite furry friends. On Saturday, August 27, the Courty's beer garden will turn into a pet oasis welcoming Sydney's felines and canines while supporting our city's only not-for-profit animal pound. All profits made from two karma kegs of Stone & Wood and Young Henrys will be donated to the Cats and Dogs Shelter. There'll be a tonne of raffles and pet giveaways on the day plus the chance to adopt your very own future best friend from a handful of pooches. So come along, bring your pets and enjoy an afternoon of brews. Because, if there's one thing that makes sipping an ice-cold schooner even better, it's knowing you're helping a pup or kitten find their dream home.
Van Morrison's Masterpieces Featuring Vince Jones And The Astral Orchestra
Beloved Australian singer, trumpeter, songwriter and performer Vince Jones has assembled a crack squad of Australian jazz musicians, with musical direction and piano by Matt McMahon, to form the Astral Orchestra. This super-group of local legends will, for one night only, take on Van Morrison's seminal late '60s and early '70s albums Astral Weeks and Moondance. These are the records that turned Morrison into Van the Man, and gave us 'Madame George' and 'Into the Mystic'. Not only were both albums critically acclaimed (although, for Astral Weeks, the road to recognition was a slow one) they were also hugely influenential for a young Vince Jones. This show at Angel Place's City Recital Hall follows two sold out performances at the Melbourne International Jazz Festival, so act fast. Astral Orchestra full lineup: Matt McMahon – piano and music directorBen Hauptman – guitarBrett Hirst – bassJames Hauptman – drumsPhil Slater – trumpetPaul Cutlan - saxaphone and fluteMichelle O'Young – violinStephanie Zarka – violinJustine Clarke – vocals

Enhanced Adsorption and Recovery of Uranyl Ions by NikR Mutant-Displaying Yeast
AbstractUranium is one of the most important metal resources, and the technology for the recovery of uranyl ions (UO22+) from aqueous solutions is required to ensure a semi-permanent supply of uranium. The NikR protein is a Ni2+-dependent transcriptional repressor of the nickel-ion uptake system in Escherichia coli, but its mutant protein (NikRm) is able to selectively bind uranyl ions in the interface of the two monomers. In this study, NikRm protein with ability to adsorb uranyl ions was displayed on the cell surface of Saccharomyces cerevisiae. To perform the binding of metal ions in the interface of the two monomers, two metal-binding domains (MBDs) of NikRm were tandemly fused via linker peptides and displayed on the yeast cell surface by fusion with the cell wall-anchoring domain of yeast α-agglutinin. The NikRm-MBD-displaying yeast cells with particular linker lengths showed the enhanced adsorption of uranyl ions in comparison to the control strain. By treating cells with citrate buffer (pH 4.3), the uranyl ions adsorbed on the cell surface were recovered. Our results indicate that the adsorption system by yeast cells displaying tandemly fused MBDs of NikRm is effective for simple and concentrated recovery of uranyl ions, as well as adsorption of uranyl ions.

Nicolo, my 21-year-old nephew, grew up sheltered. So, his parents and I worried when he moved to the city for work. It was a 10-minute walk from his bus stop to his apartment. Several weeks ago, he recounted having seen two goons beat up a guy in a nearly empty street. As the boy knew something similar could happen to him, he decided to arm himself with a self-defense weapon. Telescopic steel batons appealed to Nicolo because these provide a safe distance between the attacker and the victim, and he was good with a bat. He said security guards and law enforcers are among those who use a steel baton. It is an extendable steel bar that can be used to strike or jab an opponent, or protect against someone attacking you with or without a weapon. The length appealed to my nephew. He knew flicking a baton to expand it would take an assailant by surprise. That would put some distance between the assailant and him. He found telescopic steel baton devices online that can expand to 16, 21 or 26 inches. Their rubber handles made them easy to grip and would keep them from slipping while you were flicking. The extra reach meant you would not have to be close to the attacker to hit him. Of course, once you had stopped the goon, it would be time to make a run for it. I had not known Nicolo had gotten a steel baton until he came home one evening, all sweaty and gasping for breath. I saw the contraption, and learned about his encounter with a drug-crazed dude who suddenly charged at him in the street. Nicolo had been ready, baton in hand. When he sensed he was in danger, he had been able to respond quickly and repel the junkie. The guy had screamed in pain after he got hit in the shoulder and forearm. Steel batons seem like good protective devices if you have the chutzpah to use one.

Corporate Advocacy Program™
I resigned my position with another company in order to take this assignment and was scheduled heavily for both Weekdays and Weekends to give the FLU shots.
Since Mollen Clinic did NOT advertise in the Newspaper or other media, the old folks did NOT know that we were set up a Major Supermarket to give the shots and thus, they did not come.
As a R.N. I can work anywhere and have up to 23 phone calls per week asking for my services. MOLLEN clinics contracted with me for the month of September, October, November of 2008 and after three weeks work they cancelled most of my shifts and refused to compensate me for the cancelled shifts.
Do NOT sign on to work for Mollen as they are only interested in the money and breach the contracts made with the R.N.'s who sign on to work with them.

Ratings for Dr. Lindsay Barnes
We had Lindsay for the birth of our second child and I cannot say enough good things. She took us on at 30 weeks and when I went into labour at 32 weeks (before having the chance to meet her) she was on the ball. Fortunately the labour stopped and pregnancy resumed as normal. For the remaining 8 weeks Lindsay was wonderful and took the time to answer every question. I was attempting a VBAC and she was incredibly supportive but also realistic. She never tried to talk me out of it or scare me with stats. When the actual labour came around she was at the hospital before we were and was hands on. She has a tough love approach that I personally loved. I achieved my goal of a VBAC and I really believe that without her support and coaching it wouldn't have happened. Her home visits were great and felt like a luxury compared to our first birth through the clinic. I had struggled to breast feed my first and Lindsay worked hard and took extra time to coach me and help me get breastfeeding going. I would recommend her in a heartbeat and use her again if we ever have a 3rd!
Lindsay was unorganized and unprofessional. She told us the gender of our baby and we didn't want to know. She forgot our names all of the time and after delivery she kept forgetting what gender of baby we had. Delivery itself with her was a horrible experience. Her episiotomy was a mess and I've been dealing with prolapse because of it. I am hugely disappointed that I went with a mid-wife this birth, unlike my first birth where I used a clinic.
We found Lindsay rather inattentive during prenatal visits, for the birth itself, I haven't much to say either way about her.. The one thing I will give Lindsay is that she was helpful for post birth visits, checking on the baby and my well being. Over all, I would suggest she would be better suited to post natal care, as opposed to delivery ...
We had a terrible experience with Lindsay and would definitely NOT recommend her. Unfortunately, it was our first baby and didn't have much to compare to. The night I went into labor and made the call to the midwife, we were surprised that a student answered and was coaching us through. This student would then say she would call us back after consulting with the senior midwife who was Lindsay. Long story short, we kept being told I was in early labor each time we called - no home visit to assess at all was even mentioned. The final call we made, I think both the student and Lindsay both realized that I was way further along and told us to rush to the hospital and they would meet us there. The care ride was excruciating and I was 8cm dilated when we arrived. I pushed for 2.5 hours when finally Lindsay stepped in and called in a doctor. Lindsay and the student were both completely absent in my labor - we felt alone and confused. Lindsay was standing way over to the side on her phone off and on - it was shocking and very upsetting. They cleaned up no mess as things were happening and there was no motivation or coaching AT ALL! Our baby turned out to be a forcep delivery. When Lindsay visited us at the hospital she was extremely rushed and not personal at all. It was a very unfortunate experience because of Lindsay and her lack or professionalism, care, support and sensitivity. She was in another world every time we saw her. I do not blame the student who was training - I blame Lindsay.
Lindsay "took care" of me during my pregnancy, but luckily wasn't on call the night I went into labour. It was at times laughable how unprofessional she was and I never truly felt like she cared about me or my birth experience. She's completely unorganized, never on time and even at the end of my pregnancy did not know my name without referencing her notes (made it awkward the day she grabbed the wrong notes). I don't consider myself a high maintenance or sensitive client, but would strongly recommend against using Lindsay.
I was so disappointed to find out Lindsay was my midwife for my delivery. I had hope Tamara would be the one on call but my son decided to be 9 days late. Tamara was on holidays and Lindsay was delivering and doing the appointments. I have nothing positive to say about my experience with Lindsay. In meetings pre and post labour she would often ask me a question and then 5 mins ask me again as if she was not paying attention to what she was doing. She was very unattentive during my labour (she sat a read a book while I was in labour), when labour went late into the night she complained about how she had appointments in the morning, she argued with the nurses and seemed to be very distracted at times. She checked me and told me I was ready to push. I pushed for 30 mins and then she checked again and I was not fully dilated. She got mad at me for not pushing right (the next day she did apologize if she was hard on me). I ended up having a emergency C-section. I ended up getting a infection from the C-section and spent 10days in the hospital twice a day getting IV antibiotics. I missed out on the first 3 weeks of my sons life recovering. I truly feel if I had had a different midwife I would have a much better labour experience.
From my first appointment with Lindsay, I had a hard time connecting with her. I didn't get the reassurance from her that I needed, on multiple occasions. She was friendly and seemed knowledgeable at times, but by the end of my pregnancy I had some anxiety about Lindsay being on call when I went into labour. In the end, Lindsay was not the midwife to deliver my baby. Overall I felt that Lindsay did an ok job with my prenatal care, but she lacked the level or professionalism and reassurance-giving that I would have wanted during labour and delivery.
Lindsay delivered my two children and she knew exactly when to bring me into the hospital for the delivery of my second child when I thought it was too early! She knew the signs that I was going to deliver quickly and she met me at the hospital and helped me through a very intense and quick birth. She always provided professional care and answered all our questions thoroughly. For the first baby, she helped my daughter with her latching problems and made breastfeeding my second child that much easier. I would definitely recommend her services and since my husband and I have completed out family we are going to miss seeing her friendly face at our clinic visits.
Unfortunately Lindsay was on call when my baby decided to be born. It was happening 3 weeks before my due date and Lindsay from the beginning was trying to convince me over the phone that I am not in labor yet. She never made the trip to check on me as it turned out she was at another birth nor she made a call to another midwife to do so. I was laboring at home with my doula and was getting ready for a home birth. When my waters finally broke Lindsay realized that I must be in labor but could not come for another an hour and a half and still she did not make a call for the back up. When she finally arrived I was ready to push but then she announced that the baby is breach and we had to quickly transfer to the hospital where I had an emergency C-section. This was a very traumatic experience mostly because of Lindsay's lack of professionalism, knowledge, support and understanding. I truly believe Lindsay is not capable of caring for a pregnant and/or laboring woman.
Lindsay provided thoughtful, dedicated, and professional care. She was my primary caregiver during my home water birth and took part in the most memorable moment in my life. I felt safe, and well-understood. What I appreciated most was my post-partum care. I had a difficult time nursing and she put in a lot of effort and caring to ensure that my baby and I were able to have a healthy nursing relationship. Lindsay also spent time interacting with my 4 year old son and my husband, and included them during my appointments so that they felt like they were part of the family in the exciting adventure of welcoming our baby into the world. I would definitely recommend Lindsay as a midwife. In fact, I am sad that we're not planning any more children because that means she won't be providing care for our family any more! My experience with Lindsay was positive, enjoyable, and memorable.

Museum of Wisconsin Art opens new building
After researching and refining the history of Wisconsin art for decades, the Museum of Wisconsin Art will be able to tell more of its story starting this weekend. It will reopen in a dramatic new building nestled on the Milwaukee River at 205 Veterans Ave., West Bend - a gleaming, white wedge with twice the space for art inside.
The museum also is altering its narrative, opening up what it means to focus on "Wisconsin art" and creating a greater focus on contemporary art. »Read Full Article
'Revertigo' author Skloot appearing at Boswell
Floyd Skloot's new memoir, "Revertigo" (Terrace Books), covers many topics: a community theater production of "The King and I," New York accents, his mother's remarriage, books he tries but just can't read.
But its big subject is the unexpected, devastating attack of vertigo that struck him on March 27, 2009, and lasted 138 days. In putting together this book, Skloot writes, he realized "my work was exploring balance and its loss, how the forces of uncertainty and sudden change and displacement had shaped me since childhood, as it shapes many of us..." »Read Full Article

Then cool and contemporary jazz got more intellectual, as the dancers sat down or moved elsewhere and jazz began its long, continuing decline. »Read Full Article

Solutions for Chapter 3
The American security act of 2009, if becomes law will limit greenhouse gases from electricity generation and require electricity producers to generate a minimum percentage of power using renewable fuels. Thus, now there is a tradeoff between the electricity generation at current costs and reduced green house gases emission electricity generation with increased costs.
Efficient points: Production is efficient when it is not possible to produce more of one good without producing less of other good. For the production to be efficient all the resources in economy should be fully employed.
Total expenditure of $821 billion by the government and $208 million by electricity producers will divert funds to clean energy production. These funds could have been used for production of other activities in economy. The new law will not achieve production efficiency as production efficiency occurs when all resources are fully employed. In the present scenario the resources to be used for production of other goods and services will be used for making electricity with control on green house emissions and increased costs.

At first i thought ok maybe that was just a shipping error.. after i connected that in i turned on the computer to find the computer would freeze up during games and such. It was overheating or a problem with the graphics card.
In my opinion they did not test the computer properlery before they shipped it out if they had done so i would not have had that problem.
Customer Support was VERY rude to me via email. One guy even falsley acused me of saying rude statements to him which i did not.
They also lied and told me that they would pay for the shipping return to repair it only to email me back and tell me "oops we made a mistake we cannot pay for the shipping".
One of the support persons actually ended up insulting me to a point.
One of the worst and most unprofessnal computer companies i have delt with. I will not and encourage anyone else NOT to buy from there company. read the other reports here.
They rip people off by promising "great deals" on computers only to have them half built and not tested and backed up by rude and unacknowledgeble staff.
I was able to return it for a refund thankfully however. I will never buy from them again.

First, when they buy your items, I.E. Silverware, Gold Jewelry, Silver Coins and anything that's worth something, they melt 99% of it down. I'm letting you know this because I felt bad buying these items and lying to the seller about where it will go. Your Great Grandmother's silverware set, the antique one? Well, that's going into the fire. They care nothing about you or your items.
We tried to get everything we could at about 30% Spot Price. For numbers sake, if you brought me in $100 in silver, we'll tell you that "It's going to be hard to find a buyer for this and we'll give you $30 for it. It's going to sit on a shelf in one of our stores until we find a buyer for it". So untrue. We would buy it, send it to our sorting facility and then it'll go straight to the refinery.
Second, your costume jewlery and purses. We tell you to bring it in so you bring in other items that we would buy from you. It's a tactic that makes you think we buy everything. Which, we would. But, we don't care about that stuff, we want your Gold and Silver!
Diamonds! Yes, we will steal those from you without blinking an eye. Don't fall for "They've opened up fifteen new Diamond Mines. Even Wal-Mart has Diamond Mines, so they're not as rear as you think". For a nice 1Ct Diamond, we'd probably pay about $300-$400 dollars. Then, we'd turn around and sell it for thousands!
If you go to these shows, please do your research first! Look at the morning Gold/Silver prices. Now, factor in the melt value for the Kt. of Gold you have. There are websites that will give you spot value pricing on these items. Also, be sure to look up the value of your coins. For an average Morgan Dollar, they are worth roughly $20. The Great Estate Roadshow will tell you they're only worth $7-$10. The value on an average coin like that is for the Silver when they melt it down.
With that, all I can do is wish you the best and hope you do not get ripped off! Please, do your research! Usually, local buyers will give you a better price because of the overhead costs. They paid me $225 a days with no commision. But, that still doesn't excuse me of buying a $5000 Sterling Silver flatware set for $1000. Just so we could melt it down.
Remember, it's not the value of the items you're brining in, it's the melt value!

Hi Prodigiworld,
I just checked in two different multisite configurations and the plugin worked. Can you tell me some of the other plugins you have installed? Chances are, one of these is conflicting with my plugin. If we can identify which one, I can create a way to prevent this from happening.
The plugin calls a javascript uploader if the profile page is open. Since it hooks on the init of the admin screen, chances are, another plugin is conflicting with the uploader or is overloading my uploader function.
This could occur with any type of plugin that adds something to your profile screen.
Any ideas?
Let's get this issue resolved.
- Jesse
Hi Prodigiworld,
Just checked again with about 100 different plugins, and after going through some of your other posts I'm almost certain this is a conflicting template/plugin issue.
I'm going to mark this as resolved, as there are many other people running WPMU who have not experienced problems.
That doesn't mean I wont still help, though. 100% product support is my goal, so please send me some of your plugins or -- even better -- a copy of the error console (are you using Chrome?)
Here's my link to my support page: http://lawsonry.com/themes/support

Hi, its only work if I changes my own profiles. As Admin I thought that I will have ability to changes any of my user profiles. And it doesnt work with Fancier Author Box. Thanks!
I had the same issue when using Chrome and logged in as Admin. The plugin worked as expected after logging in as the individual users in Firefox.
I can't get this to work either. I press the button and nothing happens. I have a multisite as well.
I tried to use firefox and also Safari, but no love. I really don't want to have to log in as individual users, as I have nearly 50 users for whom I would have to do this, and frankly I just don't have the time.
Same problem here, but on a single install (not WPMU).
It seems that the button only works on the user who is currently logged in.
I hope this is a bug. If it's a 'feature', I'll have to look at another solution, as I do not have any of the users passwords (and why would I?).
Same problem here, I do not have access to all user accounts to login to each and upload. So this must be an issue with this plugin and not a conflict since it works for my user account on my profile page but not the user profile page.
It doesn't seem like the developer cares ...
To fix this issue find line 33 of easy-author-image.php and change it to
if ( 'profile' == get_current_screen()->id OR 'user-edit' == get_current_screen()->id) {
Thanks Jeff, but I don't do PHP and if the developer doesn't care about this, I don't feel good about using this plugin at all. That's very sad if it's that easy to fix :(
I was having the same issue and that fix worked for me. Thanks.

Andy has some serious "issues" that you should be aware of. People are "beneath" his "artistry." So is, cleaning up his construction mess, paying his suppliers, and completing his work. As a result, people end up with an incomplete job, a trashed house, and him doing whatever he wants. A wire in the way? No problem; he'll cut it and drop the wire into the wall - who cares if your sockets don't work, right? Same thing with plumbing, tile, and preparation work.
He bites off way more than he can chew, tries to make it look "professional" but leaves when the work is 60-70% done after trashing the premises and slowing down to below a crawl. [continued below]....
Demand several years worth of references - not just recent jobs that are hoping that he'll finish what he isn't doing. Demand that he shows you a CONTRACTOR's license and permits for any sheet rock, electrical, plumbing, framing, or any other work as well as PROOF OF LIABILITY INSURANCE.
Having spoken with dozens of ticked-off former clients, their belief is that he has "serious" mental issues including narcissistic personality disorder, passive aggressiveness (hidden things are found vandalized by him months after he leaves), and is allegedly abusing crack or speed. There are some sort of allegations of some former alcohol-related police problems as well. You should check these issues with references as well - not just with recent or current clients. Shouldn't any contractor be able to show multiple references where the work was completed to the client's satisfaction and has held up over time?
It's no wonder that he keeps skipping town to tell new people how "great" he is; no one in his old towns are willing to listen to him anymore.

1) One, Andrew Lynn, despite his many incarnations, is a one person operation. 2) Two is the number of recent years for which he can show no employment history despite not being able to collect unemployment insurance (owned his own business) and having lost his home to Bank of America. 3) Three is the number of companies that Sunbiz.org allegedly shows as being associated with Andrew Lynn (Andrew Lynn Painting, Inc, Andrew Lynn, LLC and Andrew Lynn Decorating & Home Services LLC). The first two are now inactive and not operating. 4) Four is the number of years during which this has happened - a lot of closed businesses and missing work history for one individual.
Before you ask people to trust you and bring you into their homes, please answer the following.
1) Where did you work after closing Andrew Lynn Painting, Inc and before Andrew Lynn, LLC? Please explain this two year gap out of the past four years. 2) You state that you are licensed and insured. What EXACTLY are you licensed to do and what EXACTLY are you insured for? The reason for this question is that the alleged complaints of your work go beyond painting and look more like contracting. If you do work for clients is ALL of it licensed and insured? If you agree to do work outside of what you're licensed for, who ends up paying the bills if it's substandard and needs to be redone? 3) Can you provide references for the past five years including the gap between 2008 and December 20, 2010? 4) Will your references confirm that you did work in areas that you were licensed and insured to perform or will they show that you performed work in unlicensed and uninsured areas?
Finally, you allege that you lived and worked in the Sarasota area for 30 years. Please name 3 reputable commercial paint suppliers that can confirm that you did business with them and that you don't owe money to. Will your own brother, who is a painting contractor, vouch for you, your work, or anything that you say?
If your own family or any of your suppliers won't vouch for you, why should we trust you?
Are you an owner, employee or ex-employee with either negative or positive information about the company or individual, or can you provide "insider information" on this company?

In this article, all examples of buffer overflow vulnerabilities in Linux running on Power/Cell Broadband Engine Architecture processor-based servers were developed and executed on an IBM BladeCenter® JS22 Express server, an IBM BladeCenter QS21 server, and a Sony Playstation 3 running Red Hat Enterprise Linux 4 Update 7.
Review of buffer overflows
Let's start with a quick review of buffer overflows. A buffer overflow, or buffer overrun, occurs when a process attempts to store data beyond the boundaries of a fixed-length buffer. The result is that the extra data overwrites adjacent memory locations. The overwritten data can include other buffers, variables, program flow data, etc. Overwriting this data can cause such problems as erratic program behavior, memory-access exceptions, program terminations of the crash variety, the wrong returned results, or the most dangerous thing for systems integrity: a breach of security.
Buffer overflows cause many software weaknesses and, therefore, are the basis of malicious exploits. C/C++ systems are especially prone to overflows. They provide no built-in protection to stop accessing or overwriting data in any part of memory, and they don't automatically check that data written to a built-in buffer array is within the boundaries of that array. That's why you should always support a system that does bounds checking, either by you or by the compiler and runtime.
To learn more about buffer overflows and how to avoid them, read the developerWorks article "Secure programmer: Countering buffer overflows."
Power Architecture
The POWER (Performance Optimization With Enhanced RISC) Architecture, originally developed by IBM, was introduced with the RISC System/6000 product family in early 1990. In 1991, Apple, IBM, and Motorola, known as the AIM alliance, began the collaboration to evolve to the PowerPC® Architecture, expanding the architecture's applicability. In 1997, Motorola and IBM began another collaboration focused on optimizing PowerPC for embedded systems. At the end of 2004, the Power.org consortium was launched with the goal of developing community specifications and supporting development tools that work together to facilitate integration and enhanced implementations focused on the Power Architecture.
The Power Architecture is an open architecture defined by the Power Instruction Set Architecture (Power ISA) maintained by the Power Architecture Advisory Council, which ensures compatibility among implementations and allows anyone to design and fabricate Power Architecture-compliant processors. The Xbox 360 processor and the Cell Broadband Engine processor both shine as excellent examples.
A processor implementation that conforms to the Power Architecture has four basic classes of instructions:
- Branch instructions
- Fixed-point instructions and other instructions that use the fixed-point registers
- Floating-point instructions and decimal floating-point instructions
- Vector instructions
Fixed-point instructions operate on byte, halfword, word, and doubleword operands. Floating-point instructions operate on single-precision and double-precision floating-point operands. Vector instructions operate on vectors of scalar quantities and on scalar quantities, where the scalar size is byte, halfword, word, and quadword. The processor uses instructions that are four bytes long and word-aligned. It provides for byte, halfword, word, and doubleword operand fetches and stores between storage and a set of 32 General Purpose Registers (GPRs). It provides for word and doubleword operand fetches and stores between storage and a set of 32 Floating-Point Registers (FPRs). It also provides for byte, halfword, word, and quadword operand fetches and stores between storage and a set of 32 Vector Registers (VRs).
- The Condition Register (CR) is a 32-bit register that reflects the result of certain operations and provides a mechanism for testing (and branching).
- The Link Register (LR) is a 64-bit register. It can be used to provide the branch target address for the Branch Conditional to Link Register instruction, and it holds the return address after Branch instructions.
- The Count Register (CTR) is a 64-bit register. It can be used to hold a loop count that can be decremented during execution of Branch instructions.
- The Machine State Register (MSR) is a 64-bit register. This register defines the state of the processor. The 64th bit defines whether the processor is in 32-bit or 64-bit mode (0 or 1).
Processors provide two execution modes: 64-bit and 32-bit mode. In both modes, instructions that set a 64-bit register affect all 64 bits. The computational mode controls how the effective address is interpreted, how status bits are set, how the Link Register is set by Branch instructions, and how the Count Register is tested by Branch Conditional instructions. Nearly all instructions are available in both modes. In both modes, effective address computations use all 64 bits of the relevant registers (GPRs, LRs, CTRs, etc.) and produce a 64-bit result. However, in 32-bit mode, the high-order 32 bits of the computed effective address are ignored for the purpose of addressing storage.
All instructions are four bytes long and word-aligned. Thus, whenever instruction addresses are presented to the processor (as in Branch instructions), the low-order two bits are ignored. Similarly, whenever the processor develops an instruction address, the low-order two bits are zero.
Bits 0:5 always specify the opcode. Many instructions also have an extended opcode. The remaining bits of the instruction contain one or more fields for the different instruction formats.
A program references storage using the effective address computed by the processor when it executes a Storage Access or Branch instruction or when it fetches the next sequential instruction. Bytes in storage are numbered consecutively starting with 0. Each number is the address of the corresponding byte. The byte ordering (Big-Endian or Little-Endian) for a storage access is specified by the operating system.
Cell Broadband Engine Architecture (CBEA)
The Cell Broadband Engine (Cell/B.E.) processor is the first implementation of a new multiprocessor family conforming to the Cell Broadband Engine Architecture (CBEA). The CBEA is an architecture that extends the 64-bit Power Architecture. The CBEA and the Cell/B.E. processor are the result of a collaboration between Sony, Toshiba, and IBM, known as STI, formally started in early 2001.
Although the Cell/B.E. processor was initially intended for applications in media-rich consumer-electronics devices, such as game consoles and high-definition televisions, the architecture is designed to enable fundamental advances in processor performance. These advances are expected to support a broad range of applications in both commercial and scientific fields.
The most distinguishing feature of the Cell/B.E. processor is that, although all processor elements share memory, their function is specialized into two types: the Power Processor Element (PPE) and the Synergistic Processor Element (SPE). The processor has one PPE and eight SPEs.
The first type of processor element, the PPE, contains a 64-bit Power Architecture core. It complies with the 64-bit Power Architecture and can run 32-bit and 64-bit operating systems and applications.
The second type of processor element, the SPE, is optimized for running compute-intensive SIMD applications; it is not optimized for running an operating system. The SPEs are independent processor elements, each running their own individual application programs or threads. Each SPE has full access to coherent shared memory, including the memory-mapped I/O space.
There is a mutual dependence between the PPE and the SPEs. The SPEs depend on the PPE to run the operating system and, in many cases, the top-level thread control for an application. The PPE depends on the SPEs to provide the bulk of the application performance.
The most significant difference between the SPE and PPE lies in how they access memory. The PPE accesses main storage (the effective-address space) with load and store instructions that move data between main storage and a private register file, the contents of which may be cached.
The SPEs access main storage with direct memory access (DMA) commands that move data and instructions between main storage and a private local memory, called a local store or local storage (LS). An SPE's instruction-fetches and load and store instructions access its private LS rather than shared main storage; the LS has no associated cache. This three-level organization of storage (register file, LS, main storage), with asynchronous DMA transfers between LS and main storage, is a radical break from conventional architecture and programming models because it explicitly parallelizes computation with the transfers of data and instructions that feed computation and store the results of computation in main storage.
Controlling buffer overflows
Now we'll look at:
- Changing the process-execution flow
- Overwriting a local variable in 32-bit mode
- Overwriting a local variable in 64-bit mode
(And in Part 2, we'll cover overwriting a function pointer in both 32- and 64-bit modes and provide some example code.)
Changing process execution flow
Similarly to the x86/x86_64 architectures, a given process's execution flow in Power/CBEA can be changed by the following:
- Overwriting a local variable that is near the buffer in memory of a given process's virtual address space to change the behavior of the application.
- Overwriting the saved return-instruction pointer in a stack frame. Upon returning from the called function, execution will resume at the saved return-instruction pointer as specified.
- Overwriting a function pointer or exception handler that is subsequently executed.
Overwriting a local variable in 32-bit mode
This section discusses how a given process's execution flow can be changed by overwriting a local variable.
The following example is vulnerable to a heap-based buffer overflow:
Listing 1. example1.c (vulnerable to a heap-based buffer overflow)
#include <stdio.h> #include <stdlib.h> #include <string.h> struct mystruct { unsigned char buffer[16]; unsigned long cookie; }; int main(int argc, char **argv) { struct mystruct *s; if ((s = malloc(sizeof(struct mystruct))) == NULL) { perror("malloc"); exit(EXIT_FAILURE); } s->cookie = 0; if (argc > 1) strcpy(s->buffer, argv[1]); if (s->cookie == 0x42424242) { printf("Congratulations! You won a cookie!\n"); exit(EXIT_SUCCESS); } printf("Hello world!\n"); exit(EXIT_SUCCESS); }
Listing 1 does not validate user-supplied data when copying it to the
buffer member of the previously allocated
struct mystruct using the
strcpy function, resulting in a heap-based
buffer overflow. Normal execution of the example writes the "Hello
world!" string to
Listing 2. Compilation and execution of Listing 1
$ gcc -Wall -o example1 example1.c $ ./example1 Hello world! $
Figure 1 represents the
mystruct and its members in the heap
Figure 1. The struct mystruct
Lesser Greater addresses addresses struct mystruct buffer cookie [ ][ ] Bottom of Top of heap heap
The process's execution flow can be changed by overwriting the
cookie member of
mystruct that is located right after
the buffer in memory with the
0x42424242 value
(BBBB in the ASCII character set).
Listing 3. Overwriting the cookie member
$ ./example1 AAAAAAAAAAAAAAAABBBB Congratulations! You won a cookie! $
Figure 2 represents the
mystruct and its members in the heap
segment after the overflow.
Figure 2. The struct mystruct after the overflow
Lesser Greater addresses addresses struct mystruct buffer cookie [AAAAAAAAAAAAAAAA][BBBB] Bottom of Top of heap heap
Overwriting a local variable in 64-bit mode
Now let's talk about how a given process's execution flow can be changed by overwriting a local variable in 64-bit mode. In the C language, only long and pointer data types are changed between 32-bit and 64-bit modes. Any pointer arithmetic should be performed using variables of type long regardless if in 32-bit or 64-bit mode. Pointer assignment should only be performed between other pointers or variables of type long.
The following example is vulnerable to a heap-based buffer overflow:
Listing 4. example2.c (vulnerable to a heap-based buffer overflow)
#include <stdio.h> #include <stdlib.h> #include <string.h> struct mystruct { unsigned char buffer[16]; unsigned long cookie; }; int main(int argc, char **argv) { struct mystruct *s; if ((s = malloc(sizeof(struct mystruct))) == NULL) { perror("malloc"); exit(EXIT_FAILURE); } s->cookie = 0; if (argc > 1) strcpy(s->buffer, argv[1]); if (s->cookie == 0x4242424242424242) { printf("Congratulations! You won a cookie!\n"); exit(EXIT_SUCCESS); } printf("Hello world!\n"); exit(EXIT_SUCCESS); }
The process's execution flow can be changed by overwriting the
cookie member of
mystruct that is located right after
the buffer in memory with the
0x4242424242424242 value (BBBBBBBB in the ASCII
character set).
Listing 5. Overwriting the cookie member
$ gcc -Wall -m64 -o example2 example2.c $ ./example2 AAAAAAAAAAAAAAAABBBBBBBB Congratulations! You won a cookie! $
Figure 3 represents the
mystruct and its members in the heap
segment after the overflow.
Figure 3. The struct mystruct after the overflow
Lesser Greater addresses addresses struct mystruct buffer cookie [AAAAAAAAAAAAAAAA][BBBBBBBB] Bottom of Top of heap heap

We've just scratched the surface. In Part 2, I'll show how to overwrite a function pointer and cover assembly components and some juicy shell, network, socket code samples.
