WORLD CHALLENGE, at Sherwood Country Club in Thousand Oaks, Thursday-Sunday, Golf Channel and Channel 4:
Tiger Woods apparently is taking the high road and high-tailing it out of town after this 15th edition of the annual event that benefits his foundation. Why move it to Florida, his new home state? Why not? It was having trouble finding title sponsors, Woods had to fork out some of his own cash to keep it solvent last year and perhaps it's just run its course at the Jack Nicklaus-designed track just off the 101. Since Woods traditionally skips on playing the PGA's L.A. stop at Riviera Country Club, there has been some handwringing that this could be the last time Southern Californians will be able to see him pitch, putt and drive in person during a competitive round. Chew on that while watching Graeme McDowell defend his title against a field that includes Rory McIlroy, Lee Westwood, Ian Poulter, Ernie Els (a first-time participant), Matt Kuchar, Hunter Mahan, Zack Johnson, Bubba Watson and Jim Furyk, as well as up-and-coming 20-year-old Jordan Spieth. Still pretty sweet for a tourney that's not an official tour stop and counts only toward world rankings. Plus, the $3.5 million purse is the smallest than any event on the PGA or European tours for the rest of this year. "I think we're all very surprised that we've got as many international players playing this year," Woods said. "The American players have supported our event throughout the years. But for some reason, this year we've had guys wanting to play (from around the world) and we have probably the best field we've had." So watch it and weep. Golf Channel has the first two rounds Thursday and Friday (noon to 3 p.m.); Channel 4 has the final two rounds Saturday and Sunday (noon to 3 p.m.).

They finished 35-4 and lost in the Final Four.

SEATTLE at SAN FRANCISCO or N.Y. GIANTS at SAN DIEGO, Sunday at 1:25 p.m., Channel 11 Perhaps chalk up another non-sellout in San Diego here, paving the way for a more important NFC West meeting to be seen in L.A. It depends what West Coast transplanted New Yorkers want to do with their free Sunday.

AW Welcomes Prof. Lisa Lindsay for Fall 2013 Lecture Series
On Thursday, October 24, 2013 the Atlantic Program hosted Dr. Lisa Lindsay as our fall 2013 lecture series speaker. Professor Lindsay shared research on her latest project titled, "Remembering His Country Marks: A Family History in Africa and America," which is an Atlantic-oriented biography of South Carolina freedman, James Churchwill Vaughn. Tracing the connections that Vaughn and his family members made between the U.S. South and West Africa beginning in the 19thc, Lindsay's lecture highlighted the ways in which reconstructing family histories offers a useful means of understanding how the movements of people and kinship ties form an important part of the history of the Atlantic World.

For @seattlemamadoc, a stirring social media journey
When Jenny McCarthy, a former Playboy bunny, claimed that vaccines were linked to autism, Dr. Wendy Sue Swanson knew she had to do something.
Her patients at The Everett Clinic, who saw the episode on Oprah, were concerned.
"They weren't necessarily more informed, but they were scared," Swanson says. "I couldn't wait any longer to get out on social media."
She decided her best bet to help parents get the right information was to start a blog. You could call it her "ah-ha" moment.
At that time, Seattle Children's Hospital, where she's on staff, was looking for a blogger.
Jennifer Seymour, the hospital's director of digital media and content strategy, says the marketing and communications team had been tossing around the idea of starting a blog for a year, but hadn't found the right person. The team and Swanson were working on another project when "the stars aligned," Seymour says.
"We wanted the blog to have an authentic voice and be valuable to our readers," Seymour says. "Dr. Swanson shared inspiring ideas about how to strengthen the connection between patients and providers."
It was important to both Seattle Children's and to Swanson that it be written in the doctor's own voice.
"I wanted to maintain ownership of the content, typos and all," Swanson says. "It shouldn't be scrubbed or marketed. It should be about what it feels like to be a doctor and a mom."
Swanson is responsible for writing, editing and publishing blog posts. She also manages her own Facebook and Twitter accounts. The marketing department provides her with PR assistance and promotes the blog, shares quarterly reports of the analytics, and compensates her for her time. There are two planning meetings per month; that's when Swanson and the team talk about future posts and speaking engagements.
"The content is hers," Seymour says. "She comes up with the ideas. We're not editing it. The audience wants to hear from her directly. She cares about every one of her readers and responds to them, even during her busy clinic days."
She certainly has a lot of readers. In the past three years, she's reached:
- 250,000 people on her blog
- 700,000 blog page views
- 500 media placements
- 12,000 Twitter followers
- 40 speaking engagements
For Swanson, though, it isn't about the numbers. It's about taking care of patients. Take a look at this recent tweet:
Best ROI on pediatric blogging — grabbed in the hallway by a new Mom this AM who says, "I love your blog." Metrics, schmetics. #hcsm
Controversial blog posts
Swanson isn't afraid of hot-button issues. She's written about circumcision, the HPV vaccine, and, most recently, gun control.
Sometimes, these posts draw some good ol' Internet vitriol from commentators. But Swanson isn't going to let that stop her.
"I don't want to have formalized messaging—it should be earnest," Swanson says. "I feel obligated to talk about these issues."
Seymour isn't deterred by negative comments, either.
"The way I look at is this: If you trust a surgeon with a scalpel, you can trust them with a pen," Seymour says. "She's an expert in pediatric health, and we support her."
Seymour says the blog aligns with Seattle's mission statement.
"Her passion to help parents do what's right for their children aligns with our mission—that children should grow up without illness or injury. We love that she investigates new research findings and tells parents how she would use that information herself—as the mother of two young boys, she's able to stimulate a conversation with her peers, parents, and the media," Seymour says.
Should physicians be compensated for social media activity?
Swanson sees patients at the clinic twice a week and an extra day each month. She spends between 30 and 40 hours a week on social media (learning, reading, following, reading, writing, using social tools). In addition, she also works for a local Seattle NBC affiliate, reporting every week about health issues and writing copy for its website.
After surviving cancer last year, she says 2013 will be focused on "really taking all that I've learned and being more thoughtful about my energy and work."
It's about the simple things: Instead of checking her phone first thing in the morning, she now takes more time to eat breakfast with her children.
With all the work she puts into social media, Swanson and Seymour agree that she should be compensated for her time—and so should other physicians on social media.
"I believe that being on social media is part of a doctor's clinical responsibility," Swanson says. "If they are sitting at a computer, reflecting on a new study, and using their medical expertise and training—they should be compensated. Or there should be time scheduled into their clinic days to spend on social media. That's the new reality. That's our obligation as health care providers."
Seymour says it's essential to compensate a doctor for their time on social media.
"To have a blog and spend this much energy on it—it takes time," Seymour says. "It's not only a way to reach patients or people within your own hospital walls, but inform people around the world. A physician's day is pretty packed. It's difficult for them to find extra time on the weekend or evenings. In order for them to have the appropriate time to devote to it, you have to compensate them."
Why taking care of patients fuels her work
Swanson says social media gives her a deeper connection with other doctors and families. She's made meaningful friendship with colleagues across the country, sits on the advisory board for the Mayo Clinic Center for Social Media, and is a sought-after speaker for health care conferences.
Yet she really loves taking care of patients.
"It's deeply satisfying for me to help families," Swanson says. "I don't want to give up my clinic work."
David Sibery, who manages The Everett Clinic, calls Swanson a "pioneer of social media."
"She's out in front of the curve," Sibery says. "I don't think social media has caught up to where she wants to go with it."
Being in the clinic serves her sense of purpose, Swanson says. Sometimes, people give her advice about her next career move by telling her, "You should stay in the clinic to remain credible."
Swanson laughs at that idea.
"I'm not going to go and take care of people to maintain my credibility," Swanson says. "I don't do this to be credible—I don't ever want to be seen as a doctor who is a doctor, just to remain 'credible.' This is the place that fuels my purpose. This is what drives me to go out and do the media work. Without my clinical work, I wouldn't work as hard as I do."
Seymour is happy about the partnership between the hospital and Swanson. With recent data showing that one-third of patients go online as a self-diagnostic tool, Seattle Children's knows that Swanson is in the right place.
"We made a decision to meet parents where they are," Seymour says. "So many of them are researching health info online, it's our responsibility to share our knowledge and research. What she writes and how she communicates with folks is so meaningful. We feel lucky to work with her."

"King Hancock" After the Revolution
As careful as he was to maintain his political popularity, Hancock developed rivals and enemies. In the new republic, one easy way to attack a rich politician was to tag him as having monarchical ambitions. Samuel Breck, born in Boston in 1771, recorded a sarcastic reference to Hancock in a political verse:
Madam Hancock dreamt a dream;According to Breck, the line about "a Yankee King" was a commentary on Hancock's political ambitions in the early federal period, when he enjoyed being the most important officeholder in New England and supposedly took as little notice as possible of the national government.
She dreamt she wanted something;
She dreamt she wanted a Yankee King,
To crown him with a pumpkin.
Within a couple of decades after Breck's memoirs were posthumously published in Philadelphia in 1863, authors were saying the British had sung those lines in Boston at the start of the Revolutionary War. But back in early 1775 there was no "Madam Hancock" wishing her husband to be a king. (Or, rather, "Madam Hancock" was John's aunt Lydia.) Hancock didn't marry Dolly Quincy until after the war began. Breck had actually written that British soldiers had sung other words to "Yankee Doodle," which he didn't record.
I suspect that later memories of Hancock as an American politician also colored John Adams's 1815 recollection about the Continental Congress's choice of commander-in-chief:
Who, then, should be General? On this question, the members were greatly divided. A number were for Mr. Hancock, then President of Congress, and extremely popular throughout the United Colonies, and called "King Hancock" all over Europe.In fact, in June 1775 Hancock wasn't popular "throughout the United Colonies"; he was well known in New England, and folks elsewhere might have heard about Gen. Thomas Gage's proclamation offering amnesty to any rebel but him and Samuel Adams. But Hancock had become president of the Congress only on 24 May and had hardly enough time to grow "extremely popular."
Adams carefully avoided saying any Americans referred to the man they supposedly admired as "King Hancock," but he did claim that people "all over Europe" used that phrase. Most likely, however, few Europeans had ever heard of John Hancock before the Declaration of Independence. When he visited England as a young businessman, Hancock was heartily annoyed at how little respect he got; he was used to being the biggest frog in Boston's Frog Pond.
No evidence besides Adams's letter forty years after the fact suggests that any Congress delegates wanted to appoint Hancock commander-in-chief. As with other details of Adams's recollection, what he wrote about "King Hancock" makes me doubt the reliability of his storytelling.
COMING UP: A myth about another king.

The generalized procedure for immunofluorescence labeling of adherent cell cultures involves fixation of the cells with a suitable reagent, such as paraformaldehyde, glutaraldehyde, acetone, or methanol. The organic solvents serve double duty by also removing most of the plasma membrane components, thus exposing the interior of the cell to antibodies and other non-permeant reagents. Cell cultures fixed with aldehydes require a permeabilization step with a detergent. Triton X-100 is a popular permeabilizing agent, as are saponin, Tween, and sodium dodecyl sulfate (SDS). After permeabilization, cells are treated with a primary antibody (or a mixture of two different antibodies from different hosts) followed by a fluorophore conjugated secondary antibody. In some cases, the primary antibody is labeled with a fluorophore. After immunostaining, the cells can be counterstained with other reagents to visual structural details not revealed by the fluorescent antibodies.
In the double immunofluorescence experiment presented above, a culture of Madin-Darby ovine kidney cells was fixed, permeabilized, and blocked with 10-percent goat serum before being treated with a cocktail of mouse anti-histones (pan) and rabbit anti-giantin primary antibodies. The target organelles were visualized with goat anti-mouse and anti-rabbit secondary antibodies (IgG) conjugated to Texas Red and Alexa Fluor 488, respectively. The filamentous actin cytoskeletal network was imaged with Alexa Fluor 350 conjugated to phalloidin. Images were recorded in grayscale with a QImaging Retiga Fast-EXi camera system coupled to an Olympus BX-51 microscope equipped with bandpass emission fluorescence filter optical blocks provided by Omega Optical. During the processing stage, individual image channels were pseudocolored with RGB values corresponding to each of the fluorophore emission spectral profiles.

An amendment to keep the federal dairy program within the confines of the Gramm-Rudman-Hollings deficit-reduction law was rejected by the House on a vote of 120 for and 267 against.
This cleared the way for House approval of a plan that cushions milk producers against the 4.3% cut in dairy price supports that took effect March 1 under Gramm-Rudman-Hollings. That cut lowered supports from $11.60 to $11.05 per hundredweight, thus reducing federal outlays by $80 million during the last seven months of this fiscal year.
A a result of the vote, the support remains at $11.60. The $80 million to cover the 55-cent differential comes not directly from taxpayers, but from a new assessment on dairy farmers.
Now that the first Gramm-Rudman-Hollings cuts have taken place, lawmakers are beginning to hear from those getting fewer federal benefits. This vote was the first of many tests the House will face on whether to keep Gramm-Rudman-Hollings intact or let it be eroded.

How to Fine-Tune Your Privacy Settings for Facebook Graph Search
Feb 7, 2013 5:00 AM PT
Facebook Graph Search is coming, and now -- before it hits -- is a good time to tweak your Facebook privacy settings.
What is it?
Graph Search is a new search function within Facebook. It's not yet been officially launched, but it is available in Beta. Graph Search differs from existing Facebook search functions because instead of just indexing bits of information, it indexes a large number of connections between pieces of information.
For example, Facebook's search functionality now provides people, places and things. The initial phase of Graph Search will provide the relationships between people, places and photos as well.
Some Graph Search term examples, provided by Facebook on its website: "people who like cycling who are from my hometown"; "restaurants in London my friends have been to"; "photos I like"; and "music my friends like."
Essentially, with Graph Search you will be able to look up and get results for anything shared with you on Facebook, and others will be able to do the same with things you've shared with them.
What Is Indexed in Graph?
Content set to Public will be searchable. People will be findable based on things they've shared with you, including interests and items within their profile -- for example, friends who have shared their city with you, or friends whose city is public.
Photos will findable by you if you -- or friends -- have posted or tagged them. Others will see any photos they can normally see, including photos hidden from the timeline.
Your location tags will be searchable.
What's the Problem?
What's the problem with all this? There isn't one if you believe that searching for and finding connections is an integral part of the future of social networking.
However, if your attitude toward privacy runs a bit more on the old-school side, you can control some of this information, including who can see your current city. Control can include reporting or removing photo tags; deleting photos; and removing location tags.
Step 1: Set General Privacy Settings
Click on the Settings cogwheel-like icon at the top-right corner of your Facebook page. Use a Web browser on a computer for this -- it's easier.
Choose the Privacy Settings link in the drop-down menu, and click on the first Edit link labeled "Who can see your future posts?" Select the "Friends" choice.
This setting will limit the viewing of your posts to friends, and not friends of friends.
Tip: Your About tab on your Timeline is where your current city is stored.
Step 2: Review and Remove Posts and Tagged Items
Click on the Use Activity Log link adjacent to "Review all your posts and things that you're tagged in." It's in the same Settings area you visited in Step 1.
Scroll down the page and you'll see chronological activity that relates to you -- either instigated by you or by others.
Click on the Edit icon to the right of the activity.
In the case of content uploaded by you -- like photos -- choose Delete Photo.
Warning: Photos that are untagged but not deleted can still be found by others on Facebook.
Hiding a photo from your Timeline doesn't change who can see the photo.
Tip: Use the Shared With and On Timeline filters in the Photos section of the Activity Log to see items you've hidden from your timeline but that still might be viewable by others.
Use the Report/Remove Tag option within the Edit area to request photos be removed by friends. Choose "I Want this photo removed from Facebook" and a message will be sent to the owner requesting it be removed.
Use this option for requesting an un-tag in the Posts You're Tagged In section too.
Step 3: Limit Past Posts to Friends Only
Click on the link adjacent to "Limit the audience for posts you've shared with friends of friends or Public."
Choose to limit old posts to friends -- not friends of friends and not public.
Want to Ask a Tech Question?
Is there a piece of tech you'd like to know how to operate properly? Is there a gadget that's got you confounded? Please send your tech questions to me, and I'll try to answer as many as possible in this column.
And use the Talkback feature below to add your comments!

webhamster needed a new logo design and created a contest on 99designs.
A winner was selected from 47 designs submitted by 18 freelance designers.
Logo for trypes.nl. Trypes.nl is a new social community site.
In the design brief there was a mistake, the name must be trypes.nl and not tripes.nl. It appears that tripes means something like the edible part of a cows stomach, which I didn't know. Our apologies!
Trypes is a new social community. The name 'trypes' comes from the name 'tribes' ( which means something like a social network ). This is also what the logo most show. Thema's which can be used for the logo are:
- Social networks
- People / users connection with each other
- People socializing
- Network / Networking
- A nice good font which we could use for headers also ( maybe? )
The website tripes.nl will be a new social community, which will use all good of the web2.0. It will be a very interactive website, where people can share there lifes, messages, photos, videos and more.
If the logo is really nice we might also want you to design our website and maybe also stationery, etc,
- A nice fresh logo
- Web2.0 style
- Fresh colors
- Recognizable
- Must be liked be youth and also adults
- MUST emanate a Social Network where people can connect
- Item 1...

Taco needed a new web page design and created a contest on 99designs.
A winner was selected from 41 designs submitted by 15 freelance designers.
I want this new site to look Web 2.0, modern, business like, efficient. The site (1000px wide) will need a header, a menu bar over the full width below it and then two columns (1/3 - 2/3).
orangejuice for ads
orangejuice for ads is a new website. It will allow the user (customer) to create an account, specify some settings and then receive daily updates in their e-mail. The site will display statistics as well at some point in the future.
I need a design for the homepage and a regular page for the same site, based on the same basic design.
- Header with the logo
- Main menu over the full width of the site
- Two columns below the main menu
- Orange and blue as main colors
- White background
- Web 2.0 fonts and controls (editbox, button, menu)
- Lots of room - white space
- Clear layout - efficiency and clearness are real important
- I do want rounded corners for boxes
- I don't want a lot of details
- No frills
- Not more than 3 colors, although you could use a tint for the user interface elements if it stays clear

A federal judge has ruled in favor of Microsoft over Google's Motorola Mobility division in the first of two patent trials regarding the use of Wi-Fi and other technology used in Microsoft's Xbox console and some Windows products. Motorola had filed suit in U.S. District Court seeking 2.25 percent of the net selling price of Microsoft Windows and Xbox products in exchange for licenses to its H.264 and 802.11 technology, according to the suit. That would have amounted to about $4 billion a year for use of the patents. Microsoft countered that Motorola should get about $1 million a year, according to reports.
On Thursday, U.S. District Judge James Robart ruled that Microsoft should pay Google's Motorola unit about $1.8 million, or several cents per unit as a reasonable and nondiscriminatory rate.

The suit was originally filed in November 2010 in U.S. District Court, Western District of Washington, to determine what a reasonable and nondiscriminatory rate would be. The judge's ruling allows the second patent trial to proceed, one to determine whether there was a breach of contract between Microsoft and Motorola.
"The judge seems to be on top of it and maybe it's Motorola looking to capitalize on this. They should have something to do with it and should be financially compensated, but not make it too prohibitive where they can't work with others because they charge high dollars. It needs to be a collaborative effort," said Debi Bush, CEO of CMIT Solutions of Denver. Microsoft had argued that the 802.11 standard and the H.264 standards incorporate patented technology, and in order for a company to practice the standard it is necessary to utilize technology that is covered by one or more patents, according to the 207-page document released Thursday.
The initial ruling is a blow to Motorola and to its parent Google, which purchased Motorola Mobility for $12.5 billion in August 2011.
Microsoft and Motorola have battled in court for the last several years. In addition to this suit, Microsoft charged in 2010 that Motorola's Android-based smartphones violated some of its own patents.
In a statement, Microsoft said the court's decision is good for consumers because it ensures technology can remain affordable, while Motorola issued a statement that the rates it was seeking were reasonable and consistent with others in the industry.

Post subject: Adjustable Outhaul with fast installation?
Hi! I've had a single-sided adjustable outhaul system on my primary boom (HPL hybrid; 6.0, 7.0) since I started windsurfing, so naturally I'm addicted to it (AO). The only way I can beat the more experienced sailors on a head to head run is by getting a jump onto a plane, then flattening for speed. Of course, I appreciate it's many other purposes as well.
I'm looking to upgrade to double-sided, and not spend much money, because I'm poor (and cheap).
My current (single sided 4:1) system:
+ Harken 404 + relevant lines. I should be able to upgrade for another CL244+404+lines+optional chinook clew-pulley-
(I'm not quite convinced that I absolutely need 8:1), which I could do for about $40 ($50 with the burger).
However, it strikes me that if I get a bigger sail, say 8.5, I'm going to need an additional boom. In such a case, I think it would be nice to have a system that I can quickly remove and slap onto the other boom, instead of having to get another full setup for each one. Plus, if I only need one iteration, it's hardly a "waste" to try it on my smaller (aluminum; 5.0, 5.8 ) boom too. I know AO is less necessary on the smaller sails, but also I think the smaller the sail, the less inviting the terrain usually is for floating around trying to re-rig.
So, my questions: What AO system is easy enough to install that you can quickly move it to another boom as part of your rigging procedure? Is anyone besides me actually cheap enough to do this? How much additional rigging time does it take?
My thoughts:
kit looks like a good option at under $70; I think it actually gives 8:1 with no clew burger. However, I'm not sure if the webbing looks long enough for 8:1 on a sail with a lot of outhaul range. (I'm sure sailworks made it long enough; I'm more worried about my own ability to keep the system balanced for more than 2 tacks in shifty air.)
-Any kits
the sailworks, but better for some reason?
-I considered replacing the screws in the CL244s with some sort of quick-release bolt. This might be tricky, and I don't even know if appropriate bolts exist, especially for cheap.
-Better than quick-release bolts would be a cleat attached to a boom-sized cam clamp (like the chinook boom-head clamp), or maybe webbing with a cam/lever closure.
-I might try to see how cheaply I can copy the sailworks kit
Any other ideas? I am not opposed to jury-rigging!
Thanks for any ideas, and sorry if this boils down to something stupidly simple like "just buy the sailworks!",

When I bought my 9.0, I was in a similar thinking process. I bought a large boom and installed the full AO system on it. I tought I would need something on the medium boom but waited a bit.
Finally, my large boom covers my 6.0 and 7.5 too so if I want an AO, I use the large boom. And I appreciate having a clean medium boom that I can use when I prefer it like that. So the medium boom will stay AO free: no need for an extra or moveable system.
So I would upgrade to double sided without after-tought. If you buy a larger sail and boom, just try to transfer the kit first and see if it works for you too!

The Sailworks kit is easy to use and is well thought out. It provides 4:1 on each side of the boom. (Read the instructions on the website.....http://www.sailworks.com/the-gear/lines/adjustable-outhaul-double-side.html ).
Since it attaches without nuts or any other mechanical bits, it would only take a couple of minutes to change it from boom to boom, but you could make another one with some time and effort, sourcing the parts and sewing up the webbing would be the challenge.

Sailboarder: that's a good point; actually, My current boom would fit an average 8.5, but only at maximum extension, and it's pretty squishy at that length. But I'm thinking of switching over to the sailworks style anyway - the release control seems a little more elegant.
kmf: I saw that on their page, but in looking at it I see: 2:1 at the webbing buckle, 2:1 at the single block, and 2:1 at the tailpiece. Maybe they're only counting the ropes? I guess it depends on how smoothly that cam buckle operates - when you pull the end, are you moving the entire buckle and then tightening the webbing, or does the webbing slide smoothly through as if it's another pulley? I assumed the later, but if it's the former I could understand how that's basically 4:1 (but the webbing itself still needs enough material for 8:1, unless I'm still off in my thinking).
Right now I'm leaning toward sourcing the parts myself: I think a whole kit should be: two single blocks, two buckles, 14ish feet of 3mm dyneema, and some webbing - about $40; I guess that's not as much saving as I'd hoped, but I already have one of the blocks so it's only about $28 for me. Plus, if I was to repeat the setup for a smaller boom, I wouldn't be above replacing the blocks with simple shackles.
Thanks for the responses; they're quite helpful!

Don't bother with the burgers. Instead use a double block at the clew, affixed to the sail with a bow or D shackle. That gives you an 8:1 system that doesn't cost too much, and having a setup on both booms is well worth the money. It's going to take lots of time--possibly in the middle of a great sesh--to move your system between booms. And if you need additional justification, just tell yourself that the additional range your systems provide eliminates the need to buy a couple of new sails.
To keep your clamcleats from sliding down the boom, I've had good luck taping on a thin patch of neoprene with electrical tape. You have to experiment some to get the right diameter, and you don't want to go too thick or you'll waller out the holes in the plastic straps. I try to build up the tape a little more towards the clew end, that way the plastic strap encounters a slight wedge if it tries to move down the boom, which in turn strengthens its purchase.

Also, we're not talking about huge loads here, so without having done the research, I'd speculate that you could save money by getting off-brand products. Alternatively, like most recreational equipment, the hardware you need has very little resale value, so I'd haunt CL, eBay, and the boneyard at your local yacht club to see what you can find. You'll probably have to buy the clamcleats new, but the blocks you need don't have to be any specific size, other than fairly small.

Why is a double block better than the burger? It seems you get more boom length and at least equal expense. Perhaps a block is more rigid than a burger, though? EDIT: left out "rigid"
I've actually had no problem with sliding, with a CL111 on a HPL hybrid slalom. I can see how it would ruin my day to lose a bunch of grip material though, thanks for advice.
I see what you mean about a mid session rerig - seems like it installation itself would take about 5 minutes, but adjustment could be another 10 for the new lengths. Plus I could always have my knots too tight to undo quickly. That's partly why I'm leaning toward homemade - like you said, we're not talking about a ton of force, especially with smaller sails. So, if I can get away with shackles instead of blocks and hardware store straps and buckles, the small boom system could be more like $15 total. (maybe shackles would even be smooth enough for a larger boom?)
Speaking of hardware store webbing, does anyone know what type of webbing you'd find in the kits? Is it just regular PP, and any special weave to it? I know the webbing will only be under 4:1 tension, so it doesn't need to be dyneema stiff, but I still don't want it to have any measurable stretch if possible. Do they even make webbing out any of those UHMW fibers? OK, I'm sure they do, but are they inexpensive and easy to find?
My current plan is to grab all the line I need, a block (or shackle) and a
and build a rope setup on one side, leaving the CL244 on the other. Then I'll get a side by side comparison before I move forward.

I agree, I'll keep looking for something softer and lighter (1/2" might be more appropriate). I picked that as an example of the price range, and because that cam buckle looks to have a nicely rounded bar. I could always select a material and order the sailworks buckles, but it would be nice to have all the stitching done already. (I was thinking of making the entire rope/webbing loop out of webbing only, and using some shackle with a wide bar as the pulley.)
On that note, one could go the other way and make the entire loop out of rope, if only there was some sort of
locking block
for ropes that would replace the cam buckle. I doubt that the "rope ratchet" is going to be appropriate, but I'll try to find one in a store and play around with it. Of course sailing manufacturers also have ratcheting blocks that cost about the price of an AO system.
Thanks everyone for all the help so far! I know the thread's deviated a bit, but I get caught up in DIY projects for no reason on occasion.

THE SQL Server Blog Spot on the Web
The Hyper Threading technology returned to the Intel Xeon (and Core-ix) with processor codename Nehalem in 2009.
It was first introduced with Willamette in late 2000?, and the first Xeon in 2001.
But the Core 2 architecture, 2006, in the Xeon 5300 and 5400 series did not have this feature.
As with many (potentially) performance enhancing technologies and features,
there is a glaring absence of meaningful detailed performance data that might be of help to developers and information technology professionals.
And it is not as if Intel and Microsoft do not have the budget for this.
(Note: I am deliberately using both Hyper-Threading and Hyper Threading because it impacts search.)
The complex interaction between software and advanced hardware inherently implies that
there is no magic that always improve performance without risk of negative consequences.
I am of the impression that marketing people squash anything that could be interpreted as negative
because they want victims to believe that everything will be wonderful.
On our side we should expect that it takes talent and years of experience to build
up the skills necessary to command professional salaries.
So we need to see both good and bad in order to determine
the best strategy to realized the benefits of the positive while
containing the impact of any deficiencies.
If it were not, then why staff our positions with someone more expensive than necessary?
Nehalem and later Xeon Core-ix based processor implement temporal multi-threading.
The older Pentium 4 based processors had simultaneous multi-threading.
The details of both type are covered in the references at the end and will not be covered here.
I have a brief discussion on HT in
Processor Architectures and History.
When the Nehalem-EX (Xeon 7500 series) was near introduction,
the HP benchmark team suggested that the impact of HT was in the range of 30% improvement
for the OLTP oriented benchmarks and 10% for the DW/DSS benchmarks.
I presumed that this was on the 8-socket ProLiant DL980 as benchmarks for the ProLiant 300 and 500 systems
were handled by a different group.
My expectations are that HT should have greater impact on the 1 to 4 socket systems
because it is much more difficult to achieve performance gains on the more complex systems.
A few years ago, I did an assessment of a proprietary database engine
that only did parallel b-tree searches without locking.
Scaling was nearly linear with the number threads over both physical cores and logical processors.
This was not unexpected because of the pointer chasing code means the core
executes serialized memory accesses, so there should be plenty of no-op cycles for
two logical processor to share.
As a matter of factor, 4 threads (logical processors) per core might be even better.
Apparently that SQL Server does not realize such benefit has to do with the locking.
Is there is a single resource that locks must go through?
Dave Campbell's post
Breakthrough performance with in-memory technologies
on Hekaton cites Per-Ake Larson et al article,
and mentions lock free data structures.
(I found Sasha Goldshtein material
Practical Concurrency Patterns: Lock-Free Operations
Practical Concurrency Patterns: Spinlock.
If any knows good sources, please advise.)
This might indicate that the next version of SQL Server could show more benefit from HT
and perhaps Intel should consider more threads per core in the next generation?
Ideally we should investigate HT for both high-volume small queries (non-parallel execution plans)
and low-volume large queries with parallel execution plans.
Unfortunately my multi-threaded test harness is old and I do not have time to bring it up to date.
Recently I did work on a clustered system with two nodes.
For whatever reason, one had HT enabled and another had HT disabled.
Periodically, the active node would be switched to allow for patching.
This provide invaluable data on HT performance.
The average SQL statement on this system is 1-2 CPU-ms, comparable to TPC-E.
HT was off until mid-September, on until October, off until early November,
on until mid-January and off until beginning of March.
Certain SQL statements are not impacted by HT,
and some SQL could be more than 50% faster with HT on,
even queries without a parallel execution plan.
The overall steady CPU load on the system is typically 25% during the day.
For large queries, I used the TPC-H data generator at scale factor 100 and the set of 22 TPC-H queries.
The LineItem table is 80GB because of the use of the 4-byte date data type instead of the 8-byte datetime.
The total database is 140GB.
The test server is a Dell PowerEdge T110 II with Intel Xeon E3-1240 processor, quad-core 3.3GHz,
32GB memory, and LSI MegaRAID SAS-9260 controller connected to 8 SATA 6Gpbs SSDs.
There are 2 Crucial m4, 2 OCZ Vertex 3, 3 OCZ Vertex 3 Max IOPS and 1 OCZ Vector.
The T110 only has PCI-E gen 2 slots, so I will need to get a new system for gen 3 testing.
Below is a representation of the test system.
The software stack is Windows Server 2012 and SQL Server 2012 Enterprise Edition.
Most testing was done with sp1 + cu3, with a few tests at RTM, and sp1 base.
The storage configurations evaluated were 4 x 2 disk RAID 0, 8 disk RAID 4 and 1 x 8 disk RAID 0.
All results here are 1 x 8 disk RAID 0,
but write activity was minimal so RAID 5 results should be only moderately less.
Hyper-Threading can be enabled or disabled in the UEFI (formerly BIOS, now Universal Extensible Firmware?).
Dell also allows setting the number of cores to enable.
I think is most useful in light of SQL Server per core licensing.
We can buy a single model for many functions, then enable the correct number of cores to balance performance and licensing cost.
The SQL Server DATE_CORRELATION_OPTIMIZATION setting was turned on.
It so happens that correlated dates within the TPC-H tables are within 120-days
of each other. Ship date is within 120 days of order date and so on.
The TPC-H queries are written citing a greater than condition on one date column
and a less than condition on a correlated column, so this setting helps.
If there is a not tight correlation, then the setting may not help.
In practice, it might be better to just explicitly specify both upper and lower bounds on
the cluster key column whenever possible.
Several settings were tried on the LSI SAS-9260. No read-ahead is better than read-ahead
and 128K stripe size was better than 64K, but results below are with no read-ahead and 64K
stripe size.
While the TPC-H scale factor 100 data set was used, the indexes were built different than
TPC-H requirements as I am not presenting official TPC-H results.
The significant difference is that the clustered index key on LineItem
is Shipdate+OrderKey+LineNumber, specified as unique.
This is per my practice of building unique clustered indexes,
and not to eliminate key lookups in the execution plan.
In all tests, only the execution time and CPU are reported.
Statistics generation and compile times were excluded.
Each test of the 22 TPC-H queries are from clean buffers and clean procedure cache.
From a freshly populated database, the statistics generation time is about 40 sec.
The compile time with statistics previously generated is about 4-5 sec for all 22 queries.
CPU and elapsed time were collected with SET STATISTICS TIME ON.
The DMV dm_exec_query_stats reports exactly the same elapsed time, but the worker time
is higher, perhaps including the compile time?
Below are elapsed time in milli-sec to execute each of the 22 TPC-C queries with Hyper-Threading off and on.
There was no restriction on Max degree of parallelism so HT off is DOP 4 and HT on is DOP 8
(4 physical cores).
Below are CPU (worker) time in ms for the same with HT off and on.
The sum total execution elapsed time for 22 queries is 692 sec with HT off and 559 sec with HT on.
Overall, the 22 queries run 24% faster with HT.
On the individual queries, all but one range from 0 to 65% faster.
The exception, query 15, runs 4 times faster with HT on instead of off.
Below is the elapsed time for HT off relative to HT on.
The sum total execution CPU time is 2253 sec with HT off and 3374 sec with HT on.
Overall, CPU is 50% higher with HT on.
Of course, there are twice as much available "CPU-sec" with HT on than off,
so this is not a negative.
With a perfect parallel execution plan and infinitely fast IO, all (logical) cores
should be at 100% during the query execution.
On the individual queries, CPU on all but Q 2 and Q15 range from 22 to 80% higher with HT on.
On the Q2, CPU is 137% higher.
On Q15, CPU was 45% lower with HT on than off, reflecting the 4X speedup with double the logical processors.
Below is the CPU time for HT on relative to HT off.
There is just the slight difference in the execution plans for Q15, shown below.
The first is with HT off and the second with HT on.
I do expect HT should improve the performance of this query
but it is probably reasonable to believe that most of the 4X gain in elapsed
time is attributed to the difference in execution plans.
I have no idea why the Query Optimizer would not use the same plan in both cases.
Perhap someone from the Microsoft QO team can help?
For anyone interested, I have provided the actual execution plans for the above
HT off and on sqlplan.
(Too bad the web browser does not render sqlplan files!)
Below is elapsed time with HT off and on at degree of parallelism 1.
Amazingly, performance is better with HT on at DOP 1, 20% faster!
How can this be?
When this is the only activity, only one of two logical cores
on one of the four cores is in use.
The performance should be very similar to single-threaded HT off?
The range is 0 to 63% faster except Query 17 which 14% slower with HT on.
Below is CPU time with HT off and on at DOP 1.
Below is the relative elapsed time with HT off to HT on.
Query 1 is a simple table access aggregating 591M rows over nearly 80GB,
so there can be no difference in execution plan,
and yet it is 48% faster with HT on?
If someone knows how this can be, please advise?
I could speculate that with HT on, there are twice as many logical processors,
so it is less likely an OS task would disrupt the SQL thread handling the running query.
Perhaps is so happened that thread handling the SQL query and the thread handling IO were
on the same physical processor, so data was already in L2?
These are just wild guesses.
In the comments below, Chris A mentions that SQL Server 2012 tries to fit batches
into L2 cache.
What if it estimate the amount of available L2 too high?
Then with HT on, it would presume only half that to be available?
But with nothing running on the other LP, now single-thread HT on runs
better than HT off?
I like this hypothesis, but the HT-on benefit occurs for S2K8R2 too. Its never the theories that we like!
Below is elapsed time for HT off and on at DOP 2.
Most of the individual queries are with 12% of each other, faster or slower,
except for Query 1, 28% faster with HT on.
Overall HT on is 2% faster, basically noise.
Below is CPU time for HT off and on at DOP 2
Below is elapsed time for HT off and on at DOP 4.
The range with HT on is 2.5X slower (Query 6) to 90% faster (Query 15).
Overall, 13% slower with HT on.
It is possible that both logical processors are used on certain cores
instead of a single logical processor of each physical core.
The same may have happened at DOP 2.
Below is CPU time for HT off and on at DOP 4
Below is elapsed time with HT off at DOP 1, 2 and 4.
Notice that scaling is sometimes better than 2X from DOP 1 to 2.
I discussed this super-scaling effect in
Tpch Studies at SF10
Below is CPU time for HT off at DOP 1, 2 and 4
Below is the ratio of elapsed time at DOP 2 over 1, and DOP 4 over 2.
Correction: this is actually speedup from DOP 1 to 2, and 2 to 4,
it is the ratio of elapsed time at DOP 1 over DOP 2, and 2 over 4.
The conventional expectation is the scaling should be close to linear from DOP 1 to 2,
for a value of just under 2 on the graph.
From 2 to 4, scaling should be still be good but less than 1 to 2.
If the test system had more cores, there should be reduced gains in scaling to the higher DOP.
Query 10 is an example.
As it turns out, the behavior is all over the map of possibilities.
One effect is super-scaling where the parallel execution plan is actually more efficient than the non-parallel plan.
Four queries (2,11,13 and 18) actually exhibit super-scaling at both DOP 1-2 and DOP 2-4.
Other effects are that the parallel plan is much less efficient than the non-parallel plan, but otherwise scales with parallelism.
In this case, we would expect scaling from 1 to 2 to be poor, but good at 2 to 4.
Examples are queries 6 and 15.
In addition, because of the SQL Server cost formulas, we could be expect completely different
execution plans and characteristics at different degrees of parallelism.
Below is the ratio of worker time at DOP 2 over 1, and DOP 4 over 2.
The conventional expectation is progressively higher CPU with increasing DOP to account for the overhead of coordinating the threads.
But as with elapsed time, there are radical variations in behavior.
Per super-scaling effect, CPU at DOP 2 is actually lower than DOP 1 in many cases.
Below is elapsed time with HT on at DOP 1, 2, 4 and 8.
Notice the more predictable behavior of queries running faster at progressively higher DOP,
even when the number of threads exceeds the number of physical cores.
The exception is query 15.
Below is CPU time with HT on at DOP 1, 2, 4 and 8.
Again the expected behavior of progressively higher CPU with increasing DOP
except in the DOP 1 to 2 where the parallel execution plan is more efficient than the non-parallel plan.
Below is the ratio of elapsed time at DOP 2 over 1, DOP 4 over 2 and DOP 8 over 4.
Correction: DOP 1 over 2 DOP 2 over 4 and DOP 4 over 8
Below is the ratio of CPU time at DOP 2 over 1, DOP 4 over 2 and DOP 8 over 4.
Overall Hyper-threading is a significant positive for performance.
There are unexpected characteristics so it is important to collect sufficient performance data
for HT off and on, so that anomalies can be investigated.
It is also important to have data on query performance at range of DOP values.
In a production system, one should also consider the strategy for max degree of parallelism
(and cost threshold for parallelism)
factoring in the number of concurrently running queries (with and without parallel execution plans.
The premise is that HT performance gains on SQL Server is heavily impacted by the locking mechanism.
Then the next version of SQL Server, which is expected to make extensive use of lock-free data structures
should see more substantial performance gains with HT.
This should also prompt Intel to support more logical processor on each physical core,
similar to the 4 threads on IBM POWER.

Queries barely over the Cost Threshold for Parallelism
Parallelism Strategy and Comments.
In the first, I mentioned that a parallel execution plan with an intermediate DOP may allocate
both logical processors on one core, instead of distributing threads one per physical core.
Even if using both logical processors on one core produces a 30% throughput gain,
that implies each processor running at 65% of one LP used and the other idle.
Then the threads on the doubled up core would take 50% longer than the cores with only
one active LP.
Another question is how should the threads be distributed?
Consider one thread per core, all on a single socket first, before going to the next socket,
so threads share a common L3 cache.
Potentially operations such as the Parallelism Repartition Streams might run better.
The other option is one thread on each socket first,
before coming back to the first socket.
If SQL Server could then distribute the work so that threads are assigned to access pages stored on local memory
as much as possible,
this would improve memory performance.
Of course, this would be impossible to accomplish perfectly, but perhaps good enough is possible?
Wikipedia has pages on both Multi-Threading and processors with MT in one form or another.
MT topics include the broader topic
and the specific types of MT:
Simultaneos Multi-Threading,
Temporal Multi-Threading,
along with the Intel brand name
Intel Hyper-Threading
on this topic.
Processors with MT include the IBM
POWER6 (2007) and
all 4 threads per core. POWER8 in 2013?
The Sun (now Oracle)
UltraSPARC T1 (2005) is 4 threads.
UltraSPARC T2 (2007)
and later are 8 threads.
Then SPARC T3 (2010) T4 (2011).
The newest Oracle
Intel Itanium acquired MT with Montecito (2006),
and continued with Tukwila 2010 and Poulson (2012).

Nice article. In my testing I've found that the sweet spot for MAXDOP with HT, especially in a concurrent workload, is around 150% of the physical core count per node. More than that, at least on the microarchitectures I've tested on (mostly Nehalem and Westmere), and additional threads very sharply begin decreasing in utility. (Which is to say that I don't see worse elapsed time, but rather no additional benefit; and I'd rather keep the worker thread count as lean as possible at any given time.)
My tests haven't been nearly as formalized as these, so it would be interesting to see your numbers specifically comparing MAXDOP 4/6/8. In such a test, correcting for parallel plan choice would be ideal. If you were to enable trace flag 8649 at the server level, it would force parallel plan choice regardless of the DOP-based cost changes, so it would force some plan stability and eliminate that as a variable.
Up for it?
there is definitely something to be said for MAXDOP less than the full set of logical processors. This may even apply to systems without HT, see http://www.qdpma.com/tpch/TpchStudiesSF10.html
I had to guess, I would say that there are OS and SQL Server background threads that may need to intermittently do something, so having a few cores or LP free would help? I wonder what the parallel plan parent thread needs? And I wonder what the SQL Server strategy is for division of work between threads. I think SQL Server occasionally has problems with asymmetric loop joins. On the one hand, we would like each thread to tackle a big chunk before checking with the parent on the next chunk. But we would also like to keep all assigned threads busy according to its capability, i.e., if both LP on one core are active on some, but only one LP in other cores, there should be different amount of work sent to each? I will try to take another look at 4,5,6,7,8 later.
Whenever I read your blog postings I'm always blown away by the sheer amount of effort you always go to and the level of detail you go into. Something thats quite interesting regarding hyper threading, if my understanding is correct, is that turning it on 'Splits' the on CPU caches between hyper threads. SQL 2012 batch mode is designed such that batches fit into the level 2 cache, as such it would be really interesting to see what turning hyper threading on / off would do to batch mode and monitor execution time againt CPU utilisation and level 2 cache misses.
I recall seeing something on this. If anyone could provide a link to the L2 cache size - batch size details, I would appreciate. I thought this aspect applies to parallel execution plans, but it could also be used for non-parallel plans too?
I would assume that on startup, SQL Server inquires to the L2 size. And it must determine the number of logical processors per core, to determine whether 2 (or more) threads will share the same L2. Then one must estimate the batch size to be some amount less than the L2 size, because L2 is a unified cache, shared between data and instructions and there are other data structures too.
The theory is that in processing a query, the same data may be accessed repeatedly, so if the chunk fits in L2, the access time will be very short. Now suppose that the chunk size was over-estimated, i.e., to a higher percentage of L2 than actually available for the working data.
However, a system with HT-enabled should estimate only half the L2 as available. So the single-threaded execution plan with HT on has a more CPU-efficient strategy than the single-threaded plan with HT off?
If MS would let me have source-code access, I could look into this. I am relatively good at keeping secrets, honest. OK it could be done with just the pdb files, but my debugging skills have faded and I am no longer inclined to decode assembly.
I love your very last line, I know that Thomas Kejser has done some very deep debugging stuff, and I probably don't really need to mention the likes of Bob Ward . . . ;-)
Actually there are many reasons for your threads to be improved in performance even when DOP is 1.
When there are less threads running than the available physical CPU (cores) you may guess the system will schedule a thread on each processor, thus that's why you guess performance should be similar.
I don't believe it works so.
As far as I got the way HT works it should always schedule threads on physical CPU trying to fulfill processors, so you should see processors with two threads running and processors totally idle.
In this way the system can speedup the threads by activating turboboost, i.e. having some processors (of the same CPU socket) idle it can dedicate more clock cycles to active processors.
Furthermore thrads on the same core may use L1 cache for intercommunication rather than L2.
Finally, with this scheduling logic, all processors on the same socket will be first "populated" with threads, rather than scaling on other sockets, thus avoiding processes communication between cores on different sockets (on NUMA systems).
As far as I understood the processor architecture, dual threading on the same core (physical processor) doesn't reduce the clock cycle of each thread, which remains the same.
Summurizing, HT can only bring benefits to your thread scheduling, because can speed-up the threads (turboboost) and avoid processes communication via nested level of cache

text: I've started work on a web service which contains several potentially long running processing steps (molecular dynamics), which are perfect to farm out to the fairly large (90 node) Beowulf I have access to. The primary issue is translating requests from the event driven web service, to job queues, and back again upon completion. Specifically, the major queuing systems I have immediate access to (Sun Grid Engine and Condor) only support e-mail based notification of job completion. Starting jobs isn't an issue, as my service can simply ssh over and execute shell scripts as needed to start things up, the problem is reliably being informed when the jobs fail or complete, via any programmatic method (such as executing a shell script, calling a web service via SOAP/etc, or an asynchronous message library). My other problem, ensuring that these web service requests don't starve in house jobs on the Beowulf is easily handled via the priority levels built into all the various job managers, although being able to checkpoint a long running job would be a plus (such as is supported by Condor). I am currently investigating modifications to either Condor (more complex to update, but checkpoint is useful) or Ruby Queue (very easy to update for reliable notification) to solve this issue, but wanted to be sure I wasn't overlooking any existing solutions to programmatic based queuing and receiving notifications on jobs in a Beowulf environment... -Sean

To the Editor:
I just had a little tussle with my ego, and ego won.
The Big E, normally a manageable part of me, is ruffled by the fact that the Beacon's spell-checker changed two correctly spelled words in my husband's 2/16 letter to the editor, making both of us look like…uh…mentally challenged individuals. Naiveté, spelled correctly by us (I check his work), complete with accent agiu, was rendered "nativity," and it's, meaning "it is," appeared as possessive pronoun its.
Ordinarily, I'd let it pass – the Beacon is especially accommodating to us, and Publisher Howell is the epitome of Jimmy Stewart goodness and light – but somehow, this particular "Nativity scene," absent Baby Jesus, weighs heavily on me. (Thanks for the catharsis!)

The learning curve for joining high school softball was not difficult for Amanda Penna, who had been playing the sport competitively since age 8.
But since that time, Penna also had been playing with a much different and more dangerous curve — the curvature of her spine.
Penna was diagnosed with scoliosis. The curve in the upper part of her spine kept getting worse and worse. So did her back pain.
By her eighth-grade year at Corona del Mar Intermediate, Penna said the scoliosis had gotten severe. Her spine curved 78 degrees, and it's painful just to write that. Think about how a right angle is 90 degrees, and Penna had to live everyday with a spine that was curved nearly as much.
"It was hard to sit down for a while," Penna said. "When I was about to go into surgery, I couldn't even move without taking a couple Advils a day. It was just that bad, where I would have to lay down."
It was a lot to deal with for Penna, who was then just 13, but surgery was the only option. Penna had it in September, 2009. Due to the straightening of her spine, she immediately grew three inches from 5-foot-6 to 5-9. Since then, she has grown two more inches.
The pain is mostly gone for Penna, though she said she now has two rods and many screws in her spine. It is better than the alternative.
"If I didn't get the surgery, I'd probably be having a really hard time breathing," she said.
Penna has fully recovered. She's a sophomore first baseman at CdM, and she's off to a good start to the season.
Penna, who is batting .306 this year with 12 runs batted in, has helped Corona del Mar accomplish a lot already. Last week, the Sea Kings made the championship game of the La Quinta Aztec Challenge before falling to University, 10-1.
CdM is 7-6, and can add to the win total when they play a doubleheader at Estancia on Saturday. The Sea Kings have not even won more than seven games in an entire season since 2007.
Penna is a big part of the improvement. As the No. 3 hitter, she helps set the table for senior cleanup hitter Lindsey Susolik. Her height and length also help at first base, especially in softball, where there are so many bang-bang close calls at first.
"She's just a really good team player," CdM first-year coach Kiki Muñoz said. "She's consistent. She leads by example."
This was also true as a freshman last year, when Penna batted .329 and was second on the team with 21 RBIs. She also pitched quite a bit. She provided stability during a difficult time, when CdM Coach John Felicetti resigned during the middle of the year and Jerry Jelnick took over.
Penna and her teammates just had to make the best of the situation, but she still felt nervous. In a program with no junior varsity team, was this the end?
"We weren't really close with [Felicetti], as it was," she said. "But It was scary, because we thought we might lose our program too. We thought that if no one could coach the team, we'd just have to drop softball. It was hard. It was difficult and it was nerve-wracking, but at least we got to play."
Last fall, Penna got nervous for a different reason. She separated her left shoulder while diving back to a base during an off-season drill.
She tried to play through it, which only prolonged the time she missed. This time Penna didn't need surgery, but she still didn't like watching from the sidelines. Penna wanted to show what she had to Muñoz, a former All-American catcher at Cal State Fullerton, and assistant coach Rhiannon Ousley, who helped lead UC San Diego to the NCAA Division II championship last year.
"They didn't know if we were going to have tryouts or not," Penna said. "It was frustrating ... but we didn't have tryouts, and I got better and I got to play. It was all good after that."
Things are going well for Penna, who has a bright personality and a nice smile. But usually she's the one taking the photographs, not posing for them. She is the photo editor for the CdM school newspaper, Trident.
Different interests are healthy for Penna. She has always been serious about her softball, playing in Newport-Mesa Girls Softball and training with Chrissy Haines. But Penna never became a travel-ball player. When she was younger, she shared time on the softball diamond and as an ice skater.
Before school, Penna went to practice at Aliso Viejo Ice Palace. After school, it was softball practice.
Now Penna said she wants to join a travel-ball team this summer. Softball is suddenly something she can see playing in college.
As for her scoliosis, Penna said she does still have a small curve in her lower back. If it gets more severe, she might need to get surgery again, though she said that probably won't happen.
"Every once in a while, I'll have lower back pains, but it's not as bad as it was before at all," Penna said. "Now I can just focus on getting better at what I love to do, which is softball."
She is standing taller than ever.
