Comment LINPACK/LAPACK/Netlib (Score 2) 314

by Arathon (#37527420) Attached to: Ask Slashdot: Successful Software From Academia?
right up front: I know about this only because I work for these guys, but...

there's a whole host of Linear Algebra-related software written for high performance computing environments that is attributable largely to various teams of academics throughout the past 30 or so years. It is my understanding that these libraries get used by most anyone doing high-performance computing.

$40/year, unlimited storage, unlimited uploads, will keep things private, and unlimited traffic for the photos you want to share. They use Amazon's S3 server system, which is the platinum standard in digital archival safety. Plus, they're cooler than Flickr. The only way this doesn't work is if your internet connection isn't pretty decent. Then, keeping up with the uploads could become a pain.

How Do You Store Your Personal Photos? 680

Posted by timothy from the and-where-do-you-put-the-negatives? dept.
mxhf writes "I just came back from a four-week vacation to Mexico. This is the country for Aztecs and Maya Ruins and we visited plenty of them. Needless to say we took thousands of pictures with two cameras. Having arrived back home I realize that my hard-disk does not have enough space left to hold the additional 16GB that I collected on the other side of the globe. Now, my hard disk already is 250GB. I work exclusively on a laptop and do not want to change this. I know that there are larger disks today. But I figured that the time has come to finally move my image collection from my laptop to somewhere else. But where should I go? So, how do you store your photo collections? And how do you keep backups? These are obviously images that I want to keep for my life. So the need to survive fires, burglaries, etc. I think the amount of data I have rules online storage out. Should I just get two USB disks and leave one at a reasonably save location? I think this must be a common problem today. And yes — before you ask — I do know that the first thing to do is to go through your collection and dump what is not worth keeping."

Halo Elite Cosplay Puts Others To Shame 115

Posted by samzenpus from the using-your-time-wisely dept.
AndrewGOO9 writes "Pete Mander, a special effects artist from Ontario, Canada seems like he might have either had way too much time on his hands or just really enjoys Halo. Either way, this is one of those costumes that makes all of the cosplayers at a con feel like their best efforts just weren't quite up to par."
It's funny. Laugh.

Newsweek Easter Egg Reports Zombie Invasion 93

Posted by kdawson from the it-takes-braaains dept.
danielkennedy74 writes "Newsweek.com becomes the latest in a long list of sites that will reveal an Easter egg if you enter the Konami code correctly (up, up, down, down, left, right, left, right, b, a, enter). This is a cheat code that appeared in many of Konami's video games, starting around 1986 — my favorite places to use it were Contra and Life Force, 30 lives FTW. The Easter egg was probably included by a developer unbeknownst to the Newsweek powers that be. It's reminiscent of an incident that happened at ESPN last year, involving unicorns."

Microsoft "Courier" Pictures 230

Posted by ScuttleMonkey from the bandwagon-or-shark-jumping dept.
tekgoblin writes to let us know that Gizmodo has some early shots of the new prototype "Courier" booklet (foldable tablet) on the way from Microsoft. "Courier is a real device, and we've heard that it's in the 'late prototype' stage of development. It's not a tablet, it's a booklet. The dual 7-inch (or so) screens are multitouch, and designed for writing, flicking and drawing with a stylus, in addition to fingers. They're connected by a hinge that holds a single iPhone-esque home button. Statuses, like wireless signal and battery life, are displayed along the rim of one of the screens. On the back cover is a camera, and it might charge through an inductive pad, like the Palm Touchstone charging dock for Pre."

LG Launches Watch Phone In India 109

Posted by ScuttleMonkey from the can-you-hear-me-now-kit? dept.
roh2cool writes "If you are a watch freak and also happen to be a fan of ultra rare (and expensive) gadgets, this might just interest you. The LG GD910 watch phone looks like a normal watch – except for the fact that it can double up as your mobile phone when needed. 'It is quite thin at just 13.9mm and packs in 3G and Video Calling capabilities as well. The phone is quite stylish and the front fascia is covered by scratch-proof tempered glass. It comes with a Bluetooth headset so you don’t have to keep talking like David Hasselhoff talked to his super-car KITT in the “Knight Rider” series.'"

Maryland Town Tests New Cryptographic Voting System 227

Posted by samzenpus from the super-safe-voting dept.
ceswiedler writes "In Tuesday's election voters in Takoma Park, MD used a new cryptographic voting system designed by David Chaum with researchers from several universities including MIT and the University of Maryland. Voters use a special ink to mark their ballots, which reveals three-digit codes which they can later check against a website to verify their vote was tallied. Additionally, anyone can download election data from a Subversion repository and verify the overall accuracy of the results without seeing the actual choices of any individual voter."

oranghutan writes "Computerworld is reporting Canonical has made available the Release Candidate of its latest Linux-based operating system, Ubuntu 9.10, on the same day Microsoft launched the long-awaited Windows 7. 'The upcoming Canonical release, which is code-named Karmic Koala, is the latest version of the popular flavor of the Linux OS. The development release on Thursday pushed the OS one step closer to final release, which is due on Oct. 29, according to the company's release schedule Web page. An image of the OS is available for download on Ubuntu's Web site. Test versions of Karmic Koala RC available for download include the server, desktop and netbook versions.'"

Millions of scientists? Really? This is one of my least favorite arguments for anything scientific, ever. Let's all please face the truth that the vast, vast majority of scientific theories (even those which have been firmly established for centuries) have only ever been verified by numbers of scientists in the thousands, if not hundreds. Most science, while still good science, isn't something just anyone can verify. And it is not remotely true that millions of scientists have somehow verified the current theories of global warming.

Having actually RTFA (I know, I know -- "what?!?"), I felt like it was a pretty fair assessment of the situation. Particularly, I felt like the emphasis was on the disingenuousness of Microsoft's claims that 32-bit systems could not support >4GB of memory (not on the possibilities of illegality). Further, your analogy is faulty in multiple ways, because Ford advertises the car as having a rev-limiter and speed-limiter, and advertises these things as being safety features. Microsoft, so far as I can tell, is not being upfront about its market segmentation, and is attempting to hide behind a wall of misinformation about 32-bit systems.

I've seen plenty of pointless Microsoft-bashing articles here at Slashdot. This doesn't seem like one of them. I'm not ashamed to say that I learned a lot from it, and that I wasn't previously aware of the details surrounding PAE (things I never would have discovered unless they were highlighted on a tech-news digest site like Slashdot, since I don't regularly peruse websites dealing with Windows-specific kernel research).

Left 4 Dead 2 Announced For November 231

Posted by Soulskill from the we-need-a-zombie-topic-icon dept.
hansamurai writes "Left 4 Dead 2 has been announced at E3, and a trailer for the game has surfaced. It will be released November 17, 2009, just a year after the first game. Gameplay changes include a new focus on melee weapons, especially the iconic anti-zombie weapon, the chainsaw. The cast of characters is brand new, but the plot appears to take place during the same zombie outbreak." The game is being developed for the PC and Xbox 360, and Valve says it will make use of a new version of their AI engine, which has the ability to "procedurally change weather effects, world objects, and pathways in addition to tailoring the enemy population, effects, and sounds to match the players' performance." Rock, Paper, Shotgun got the chance to do a hands-on preview, providing details about the gameplay and confirming that "it's a coherent new imagining of the game, this time bigger, smarter, and far more elaborate. Oh, and gloriously more gory."

Submission + - Humor in code: unprofessional or not? 2

Submitted by DrVomact
DrVomact writes: Do you ever inject humor into the comments of your code or—heaven forfend—into the code itself? I recently had a "code review" of a Perl automation program I had written for my department. The salient criticism that emerged was that there was "sarcasm" in my comments, and that this was unprofessional. In retrospect, it was not surprising that the criticisms concentrated on my comments, as no one else in this group does much programming (the PHB claims to have "been a coder" once upon a time...I think he wrote COBOL on punch cards); nevertheless I was dumbstruck. What kind of world is it where you aren't allowed the occasional funny comment in your code? Do we have to be serious all the time? I asked a programmer in the "R & D" group of this paleolithically conservative company I work for, and he responded with a complete unsolicited psychoanalysis: he advised that I should develop a "professional personality" that was different from my real one I use at home. I was shocked—nay, mystified: where do you learn how to do that?

But let's concentrate on the smaller, more manageable issue: is humor in comments truly verboten? Am I the only one who makes the occasional light remark, or even a self-deprecating reminder to "Change this, you idiot...what were you thinking"? I've resolved to take the humor issue to a jury of my peers: to wit, the esteemed denizens of Slashdot.

I received an annotated copy of my code from my PHB, pointing out all my lapses into "unprofessionalism." Here are a few of the lines from my program that were deemed "unprofessional", along with my comments, and meta comments). I cannot actually guarantee that there is any genuinely funny stuff here, only that my completely humorless PHB suspected that it might be tainted. (Sorry about the lack of indenting...couldn't figure out how to make Slashdot's subset of HTML do that.)

BEGIN {
if ($^O eq 'MSWin32') {
use Win32::Console;
Win32::Console::Free( );
}
}
Weirdly, nobody thought this was at all funny or objectionable.

# Set the directory if we got lucky
This was in a set of nested conditional tests that tried to find a file, no matter what crazy place the person running the program had stuck it. I fail to see this as sarcasm...I call it "cheerful optimism".

# Fix nasty problem where...
Comment in code that fixes crazy stuff in input files. Apparently, the word "nasty" is nasty.

$sysreturn = $proc->wait; # This gets exit code of process (it's already gone, so it's not really going to wait)
The parenthetical comment was marked as objectionable. You got me; I thought this was a potentially confusing line of code, and that the comment helped.

} else { # For all others, we just need to recover the original declarations that got eaten by the XSLTs
The word "eaten" was deemed unprofessional, sarcastic, or something.

my $status = shift @_; # 1 means the error causes certain death, undef or 0 means it's a warning (user gets to try again), 2 means it's a "notification"
Describes possible values passed to an error handler; "certain death" was deemed objectionable. Perhaps it was construed as a threat?

my %args = @_; # Stuff arguments into a hash, so we can look them up one at a time
"stuff" is an offensive word, apparently. All instances of "stuff" were marked as offensive. Good thing I didn't use "slurp", or "suck", huh?

if($name ne "subsection") { # We want the minor stuff included with first subsect file
To my great consternation, "stuff" is objectionable both as a verb and a noun! I think maybe PHB was using search-and-replace for his code analysis, though.

$button_text="Bummer!"; # It's NOT OK, man!
This one caused the most outrage. It's actually part of the code, unlike the other cases—it's the text of a button in a fatal error dialog. I completely hate when an application notifies me of a fatal error and asks me to click a button labeled "OK"—as if asking for my approval for having screwed up. Like my comment says...it's not OK. PHB wanted "OK", but I finally changed it to "Exit".

So, I ask you, my peers of Slashdot, to pass judgment on me: am I hopelessly unprofessional? Or have I discovered the real reason why so many programmers don't comment their code?

Mathematics Reading List For High School Students? 630

Posted by timothy from the flatland-to-hawking dept.
Troy writes "I'm a high school math teacher who is trying to assemble an extra-credit reading list. I want to give my students (ages 16-18) the opportunity/motivation to learn about stimulating mathematical ideas that fall outside of the curriculum I'm bound to teach. I already do this somewhat with special lessons given throughout the year, but I would like my students to explore a particular concept in depth. I am looking for books that are well-written, engaging, and accessible to someone who doesn't have a lot of college-level mathematical training. I already have a handful of books on my list, but I want my students to be able to choose from a variety of topics. Many thanks for all suggestions!"
