bergeron76 asks: "Like many of you, I look at CRT and LCD displays constantly when I'm at work and when I'm at home (and even when I'm in my car). As a result, I was wondering if any of you have any neat ideas or ways to help reduce eye strain and dryness while looking at displays continuously? I've tried vitamins, eye drops, increased blinking, and combinations of glasses / contacts with little success thus far. People make assumptions about me because my eyes are constantly blood-shot, and I'm wondering what I can do to heal my eyes? I recently heard about Punctum Plugs and was wondering if anyone has had any experience with them and if they're worth the cost. They're little plugs that reduce the size of your tear ducts so your eyes retain more fluid and stay 'lubed'. Does anyone have any experiences with these or have any other recommendations for reducing eye strain and dryness (aside from not computing)?"

Kavau asks: "I've recently entered the world of digital photography, and bought a pocket-sized digital. While the resolution and the color accuracy are very nice, I was utterly disappointed by the (lack of) quality of the zoom lens: It has a clearly visible barrel distortion, especially in wide angle, so that straight lines appear curved in the picture. This is especially annoying in architectural shots or cityscapes. While grumbling about this shortcoming, I suddenly realized that I am dealing with digital imaging here: In principle it should be no problem to measure the distortion, and then to correct it with a digital mapping. Other lens faults such as vignetting could also be corrected. Now, since I don't want to reinvent the wheel, here is my question to Slashdot: Do you know of any open-source tools that deal with issues such as (1) applying general analytic transformations to a picture, (2) specifically correcting for barrel distortion, or (3) determining the amount of distortion from test pictures? Also, since people probably had this idea before, does anyone have experience with this issue that he/she wants to share, or some resources to point out?"

corporal_clegg asks: "I bought a Sharp 27" TV a year or so ago to serve as a second TV and PS2 gaming platform. When I recently attempted to play a DVD through the game console, the VChip kicked in and presented a beautifully rendered black rectangle on the screen. No amount of menu manipulation on either the game console or the TV can remove the VChip blocking; both system menus report the VChip as disabled, yet it continues to block all programming: golf, kids shows, everything. This occurs if the game console is attached and operating or completely removed. Of course the operating manuals provide no help on addressing these issues, and the manufacturers' web sites are likewise useless. So the question is: does anyone out there in slash-land know how to identify and remove, bypass or hardware reset the VChip/ blocking technology? I am very comfortable working at the board level and would much rather crack my case and fix this problem myself than take an 80lb TV to a repair shop only to be charged it's replacement cost to address the problem."

halfgeek asks: "I was just considering how keyboard-centric I've managed to make my setup, even under the mouse-hungry Windows GUI (no shouting; I regularly SSH to my Linux routing box for experiments, bring up VMWare when I need some X, and can't live without Cygwin). Almost everything I would want to do can be done without moving a hand to the mouse. I can open up an SSH to my server with Win+Shift+V, bring up a calculator with Win+C, run a one-shot console command with Win+0, open up the MW dictionary website to a highlighted word by hitting Ctrl+C (to copy) and then Win+Enter (to look up the contents of the clipboard). (Much of this is implemented with Perl programs and WinKey.) I also make frequent use of the volume knob and mute button built into my Logitech keyboard. If there is any good route to finding the keyboard I want with all the features I'm thinking of at a justifiable price, whether prefabricated or a wicked mod, I would just love to know about it." There are quite a few options the submitter is looking for, but it basically boils down to is this: the more keys, the better. What keyboards have you found, in your browsing travels, that have been stuffed full of useful features?

A Pride of Lyings asks: "I'm having a devil of a time finding a good editor or IDE aimed at HTML/XHTML/CSS/JavaScript/JSP/XML that meets the following criteria: CVS integration (VSS integration would be nice but not required); stellar UTF-8 support (internationalization is a big big deal now); correctly recognizes and highlights HTML, JSP, JS, and CSS within a single file; does some rudimentary auto-completion; is easily configurable; runs on Win2k (oy vey); supports bookmarks of various kinds; supports code collapsing; and affordable. I'm at a loss and rather fatigued from kicking all of these tires, so I'm throwing it open to you: what do you use for your front-end work? What makes it good?"

Brian J. asks: "I've recently completed a manuscript for a novel that depicts a heist involving elements of the Information Technology industry. Basically, a quartet of laid-off technology workers think they're going to get revenge against their former employer, but it doesn't work out that way. I was wondering if Slashdot knew of author's agents or editorial staff at publishers who have an affinity for technology, especially technology fiction, to whom I could send a query letter."

arys asks: "I've been looking around for a good book on the GRE Computer Science subject test but all I found were a book that is out of print and an other that has the worst reviews possible. What I want to ask is those of you that have taken the test, how did you prepare for it?"

ExcerLee asks: "Our team is going to build a MySQL (load-balancing and fail-over) cluster for the Cluster World Expo in the end of June. This cluster is going to have at least 10 nodes, and will use dual-opteron systems from Polywell Computers and SuSE Enterprise Linux for AMD64 from SuSE. While we are working on this hefty cluster, we wonder if this is the biggest MySQL cluster has ever been built. I googled with terms like 'biggest mysql cluster', but didn't find much." If you've run a MySQL cluster before, how large was it and how well did it perform? Krow: I have been told of much larger clusters then this; Slashdot DBs total 6 machines with 18 processors, and LiveJournal has one of the most complicated clusters I have ever seen set up.
