Errata Prompts Intel To Disable TSX In Haswell, Early Broadwell CPUs

CajunArson Re:Not all that surprising... (131 comments)

Nobody has been robbed.
TSX today works exactly as well as TSX worked yesterday, and considering that Haswell has been on the market for over 1 year, I assure you that anybody who has been chomping at the bit to use TSX has been using TSX.

If the TSX erratum were trivially easy to trigger, then this article would have been posted last spring before Haswell even launched.

Intel has done the responsible thing by acknowledging the bug (trust me son, AMD & Nvidia often don't bother with that part of the process) and giving developers the OPTION to either use TSX as-is or disable it to ensure that it cannot cause instability no matter what weird operating conditions can occur.

Tell ya what, why don't you take all your nerd-rage over to AMD or ARM where they won't rob you of all kinds of advanced features that they just don't bother to implement at all.

Errata Prompts Intel To Disable TSX In Haswell, Early Broadwell CPUs

CajunArson Re:Bought a 4770 instead of 4770K because of TSX (131 comments)

You can still "play with this instruction" all you want.

What happened here is that a third party developer managed to uncover a corner case where certain interactions with TSX can lead to instability. In order to be safe, Intel acknowledged the bug (a refreshing response) and is now giving you the OPTION to disable TSX if you feel that it could impinge the stability of a production load.

So basically: Go ahead and play with TSX all you want, but be aware of the errata and that it's theoretically possible to hang your machine in some corner cases.

Errata Prompts Intel To Disable TSX In Haswell, Early Broadwell CPUs

CajunArson Re:Not all that surprising... (131 comments)

Uh.. given that sort of standard, no Android application has ever been developed since the x86 PCs that are used to develop 100% of Android applications lack practically all features of the ARM SoCs that run those applications (the only exceptions being the newer Baytrail Android tablets that are also x86).

Also: There's a space of about a million miles between "TSX ALWAYS FAILS EVERY SINGLE TIME NO EXCEPTIONS AND CAN NEVER BE USED EVAR!!" with "Oh, we found through extensive testing that under certain conditions TSX can cause issues. Don't use it for your nuclear power plant control system, but it's perfectly fine for non-critical testing. Oh, and just to be safe, we've made a microcode update to disable it."

Long-Wave Radar Can Take the Stealth From Stealth Technology

CajunArson Duped article and not insightful (275 comments)

Articles like this have been around since the 1980s and have appeared on Slashdot before in regards to practically every stealth aircraft in existence including at least the F-117 and the B2.

Here's the kicker though: The long-wave radars that can sort of track stealth aircraft aren't able to track them with the precision needed to get a missile up there to shoot one down. If an adversary already knows that you are sending planes into a general geographic region, then the long-wave radar doesn't really tell them anything that they didn't know already.

Anyone in the military who has dealt with stealth technology will tell you that "stealth" is much more than a coating or wing shape that magically makes your airplane disappear. It's a whole strategy that uses technology + suitable tactics to make stealth work in practical situations. Stealth aircraft are not completely invisible and do not have to be completely invisible to be effective.

Court Allowed NSA To Spy On All But 4 Countries

CajunArson Uh... Yeah? (242 comments)

Sorry, but I'm not going to get my panties in a bind that the NSA is spying on other countries' governments considering:
      1. That's the NSA's freakin' job.
      2. Anybody who thinks that the only country in the world that spies is the U.S. is either an idiot or a liar.

White House May Name Patent Reform Opponent As New Head of Patent Office

CajunArson Re:Extremely scary (211 comments)

Uh... as somebody who knows a LOT more about patents than you do... what you just said is a complete (and likely intentionally disingenous) misreading of a relatively simple part of the statute that is merely there to prevent a substantial loss of patent term due to the bureaucracy at the USPTO taking too long to do their jobs (which they often do, being government bureaucrats).

Fascinating, so what part of patents having a fixed maximum 20 year lifetime is not "limited time" to you?

Are you still stuck with Windows 95 where anything beyond 49.5 days is considered infinity because the computer crashes?

Belief In Evolution Doesn't Measure Science Literacy

CajunArson Here's an inconvenient question (772 comments)

Inconvenient question:

You need brain surgery. Who would you want to have perform brain surgery:
1. Good party-line atheist who recites a firm belief in evolution but has shaky hands.. but who cares, after all your brain is just a randomized mix of mutations, so why should it matter? Don't you BELIEVE in evolution?

2. Religious whackjob (gasp! he may even attend a non-atheist church!) who has a detailed understanding of the brain structure and functions. After years of studying the brain, he may even secretly harbor the politically incorrect belief that your brain isn't just a random hodge-podge of mutations.

P.S. --> This doesn't necessarily mean that he disagrees with evolution and mutation as a mechanism for change or that there is common DNA across a large number of species.

Oh, and for those of you who think that anybody who has any religious beliefs is obviously too stupid to be a brain surgeon, you obviously haven't met very many brain surgeons.

Azimov even wrote a story about a similar situation involving robots and an orbiting solar power station back in the 1940s.

U.S. Drone Attack Strategy Against Al-Qaeda May Be Wrong

CajunArson But But But... (433 comments)

We've been told that Al Queda isn't real and that there aren't really any terrorist organizations. It's all a neocon plot.

So basically, how can drone strikes or any other strategy be effective or ineffective against something that doesn't exist?

Aereo To SCOTUS: Shut Us Down and You Shut Down Cloud Storage

CajunArson Sensational Summary is Sensational (342 comments)

Areo would like for all of us to buy into their fairy tale that their service == the entire cloud, but it was blatantly obvious from the oral arguments (that the submitter likely never listened to or would even comprehend if he had) that the justices were going out of their way to make sure that any ruling would not have an impact on services like Drop Box where the service itself has nothing to do with the content being "cloud" stored.

Intel Pushes Into Tablet Market, Pushes Away From Microsoft

CajunArson Re:Is it dead? (110 comments)

If you had read his comment in context you'd realize that he's saying this: If Intel Baytrail parts can run full-blown Windows 8 with good performance and battery life that's at least on-par with ARM Android tablets.... what do you think will happen when products come out where those same chips get to run Android instead?

How Does Heartbleed Alter the 'Open Source Is Safer' Discussion?

CajunArson Re:Mr Fixit (582 comments)

" just about every SSL-encrypted internet communication over the last two years has been compromised."

No, it really hasn't.

It's accurate to say that just about every Open-SSL encrypted session for servers that were using NEW versions of OpenSSL (not all those ones out there still stuck on 0.9.8(whatever) that never had the bug) were potentially vulnerable to attack.

That's bad, but it's a universe away from "every SSL session is compromized!!!" because that's not really true.

Meet the Diehards Who Refuse To Move On From Windows XP

CajunArson WTF?? (641 comments)

Premise of the Story: XP is older than Dropbox and therefore is useless. Let's go find some people who use XP and then talk about Dropbox.

In other news: This so-called story is a thinly veiled ad for Dropbox that finds interesting ways to drop the word Dropbox into a completely unrelated story!!

Russian GLONASS Down For 12 Hours

CajunArson Re:Intentional (148 comments)

If by "very recently" you mean 14 years ago (literally in the 20th century) that selective availability was turned off.....

As for your other points:
1. The U.S. did not degrade any civilian GPS when they invaded Iraq.

2. If you honestly think the Ukranians are beholden to GLONASS... which doesn't even work for the Russians a large portion of the time.. and are somehow too stupid to buy commercial GPS products that are made in Taiwan and used by the rest of the world, then I have a bridge to sell you.
Hell, even the Russians use GPS (quietly) even though they tout GLONASS because nationalism.

Scientist Live-Blogs His Lab's Attempts To Generate New Type of Stem Cells

CajunArson Meh... BORING (20 comments)

So all he's doing is a boring experiment and live-blogging it?

Sure, that kind of link-bait would have been fine back in 2002 when "blogs" were all cool.

If Slahdot's standards hadn't dropped so much recently he would have had to do the following things to get on the front page:
1. Print the rats with a a 3D printer.
2. Put the rats ON A DRONE.
3. Use the rat-drone to uncover a secret NSA program that has already produced the stem cells to INVADE OUR PRIVACY.
4. Prove that stem cells create global warming.
5. Write a lengthy academic paper that has nothing whatsoever to do with points 1-4 but instead states.. without coming to a firm conclusion.. that Christians* are inferior forms of life because jargon.

* But not muslims, because even though we talk the big talk we're really a bunch of sniveling cowards. Hey, tomorrow is Sharia tuesday!

IPCC's "Darkest Yet" Climate Report Warns of Food, Water Shortages

CajunArson Well you're partly right (703 comments)

The droughts in California ARE man-made, but they have nothing to do with the Global Warming boogy-man and have everything to do with 2 important facts that people seem to forget:
1. That part of California is a freakin' desert and no, it didn't turn into a desert overnight because of Global Warming, it was a desert long before humans showed up.
2. California's intentional man-made mismanagement of its water supply to dump water for bait-fish and for Mexico and refusal to build new reservoirs to store water from years when it has been plentiful has caught up to it now that we see California's climate doing exactly what it should be doing.

But go ahead, blame Global Warming and burn a few witches at the stake since radical religious fanaticism with a thin veneer of "science" painted over it has now replaced rational thought.

Running Old Desktops Headless?

CajunArson CajunArson writes  |  more than 4 years ago

CajunArson (465943) writes "I have recently dug up an old P4 that is in fine working order and done what any self respecting Slashdotter would do... I slapped Linux on it to experiment making an NFSv4 server. One other thing I did was to remove the old AGP video card to save on power since this is a headless machine. Now... I removed the video card after the installation, and I'm doing just fine as long as the machine will boot to a state where networking works and I can SSH to it.

My question for the Slashdot audience is: Is there a good solution to allow me to login to this box if it cannot get on the network? I'm looking for solutions other than slapping a video card back in. In my case, I will have physical access to the machine.

A few caveats to make it interesting: This question is for plain old desktop/laptop systems, not network servers designed to run headless. Also, I am aware of the serial console, but even "old" machines may only have USB, and I have not seen any good documentation on how and if USB works as a substitute. Finally, if there is any way to access the BIOS settings without needing a video card that would be an extra bonus, but I'm satisfied with just local OS access starting from the GRUB prompt. I'm all ears for advice from any Slashdotters with these setups running."

Intel open-sources parallelization Framework

CajunArson CajunArson writes  |  about 7 years ago

CajunArson (465943) writes "An interesting article over at Ars Technica discussing Intel's recent release of its">Thread Building Blocks 2.0 templating library for C++. This library provides a higher level of abstraction for writing parallel code than normal POSIX or Windows threads provide. It has been pushed by Intel in the past as a similar concept to OpenMP, although its template nature means it is much more focused on C++.

Some interesting notes on Intel's earnestness in open-sourcing the project: Released under GPL version 2, it runs on non-Intel CPUs (even non-x86 as in the G5), and it is already ported to Linux and Solaris as well as Windows."

CajunArson (465943) writes "The Beryl Project which is a fork of the well-known Compiz desktop compositing project has just released version 0.2.0. The anouncement is here.

Having used Beryl from the SVN tree I can say that it has made quite a few improvements, and while it continues to borrow from the Compiz core it also has some fun plugins like the group plugin and wall plugin that can actually help usability on the desktop in addition to just being pretty eye-candy."



Carnegie Mellon MSIN Master's Program?

CajunArson CajunArson writes  |  more than 12 years ago

Well this is my first slash-blog entry, lets see who'll bite!

I am presently an undergrad at Purdue University and will finally be graduating with a BS in Computer Engineering in May.

My number 1 choice for graduate schools, Carnegie Mellon, just accepted me into the MSIN Master's program. If you are a current or former student in this program, is it a good idea? I've studied all the material on the CMU site, and it looked so interesting that I specifically applied to that program. What have your experiences been? Has it met your expectations?

Thanks for anything you can tell me!
