  1. Re:Python for Scientific use on Matplotlib For Python Developers · · Score: 1

    I'd also add that when it comes to shipping code to a client, pointing them to a Python download vs. shelling out for a MATLAB license can be a factor as well. I like MATLAB but there's no denying there's a degree of sticker shock with it.

  2. Re:Python for Scientific use on Matplotlib For Python Developers · · Score: 2, Informative

    That echoes my experience. I generally prefer Chaco for plots in Python since it seems to handle large datasets better than matplotlib (although matplotlib seems more functional), but matplotlib is comfortable for MATLAB users. I'm working on a SciPy project with a couple of MATLAB refugees and they love matplotlib.

  3. Re:Anything similar for Wii? on XBMC 'Atlantis' Beta 1 Released, Now Cross-Platform · · Score: 1

    I haven't tried it recently but Sockso seemed to work fairly well as I recall. Music only and only MP3s at that but apparently the latest version(s) offer on-the-fly MP3 conversion.

  4. Re:Advantages over computer - HDTV? on An Early Review of Roku's Netflix-Streaming Appliance · · Score: 1

    Yep, that's why I'm seriously thinking about picking it up for my wife-no Instant Viewing on Macs, Linux, or anything Not Windows. So in reference to a comment above-it doesn't matter how technically savvy she or I or the neighbors are if we don't have Windows machines.

    I suppose it'd be different if I had a virtual Windows machine somewhere, but as I don't it seems to me that the startup costs for us to use Instant Viewing favor Roku.

    If you're desperate (?) to get your hands on one of these, I noticed the other day that ZaReason's got them too. Don't know if they're 100% the same, but they're the same price and so possibly worth a look.

    Can't vouch for any of these, having never tried 'em, but worth a look perhaps.

  7. That's the NDA process for you on AMD NDA Scandal · · Score: 4, Informative

    Having gone through the NDA process a few times, it's been my experience that it's really a negotiation and rarely a "take it or leave it" affair-they wouldn't be talking NDA if they didn't want to talk to you in the first place, so there's usually some flexibility.

    What seems to happen is one or both sides offer an initial NDA that's insane (I think just to see what they can get away with, really); then the idea is to try and negotiate towards a sane(r) middle ground. So without knowing any details, the newspaper could have countered with a suggested NDA of their own, and walked away from the table if AMD wouldn't bend. No story for the paper in this case, but AMD also doesn't get the publicity it needs. If it happens enough with other media organizations, AMD ends up having to be a little more flexible if they want any coverage at all.

  8. Re:Barriers/Lights on The Science of Bridge Collapse Prevention · · Score: 1

    Disclaimer: I'm involved in the R&D of a similar system (uninformative pic here). At least it runs Linux though. :)

    That's usually the biggest expense for these systems. It's actually pretty easy to put together the data acquisition side of things-you just need a couple of ultrasonic sensors, storage, and a good A/D board. The hard part is in the data analysis. The way it's normally done now, you acquire reams of data and a PhD. pores over it and pronounces judgement.

    Once you get to know a structure a little better though, you can automate a lot of this and this really helps drop the false alarm rate. Problem is, it takes a while to build a big enough library of data, and funding is scarce.

  10. Re:Say what??? on The Science of Bridge Collapse Prevention · · Score: 1
    I assume these actually listen for some kind of metal stress sound, rather than actual failure?

    Yep. Say you're looking for cracks. A crack usually grows in fits and spurts-stress builds at the tip (growing edge) of the crack, until the crack grows a little and the stress drops. It's this sudden jump in size that you actually detect with acoustic emission. By the time you get to the metal snapping phase of failure, your acoustic emission sensors have been ringing like bells for weeks/months/years.

  11. Re:Barriers/Lights on The Science of Bridge Collapse Prevention · · Score: 1

    It turns out that for acoustic emission, you can luck out sometimes so that one type of damage behaves differently than another, or in the way noise behaves. Usually if you compare signal amplitude, duration, frequency, etc., you can make an educated guess as to what's going on.

  12. Testing Isn't Easy on The Real Reasons Phones Are Kept Off Planes · · Score: 3, Informative
    Speaking as someone who's tried to get gear flight certified, I can tell you that testing is never easy. Granted, it's definitely easier to get something approved that isn't going to be part of the plane but rather just another carry-on, but there's still a lot of work involved.

    I think it probably boils down to cost and caution. The testing is expensive, and nobody wants to be the one that approved cell phones if they end up causing a plane crash.

    A friend of mine that's a rabid Star Wars fan was grousing about this yesterday, even as he talked about when he'd pick them up.

  15. Go Embedded on How to Run a Computer in a Sub-Zero Environment? · · Score: 1

    Find yourself a good single board computer with an extended temperature range. Within the PC/104 and PC/104+ families it isn't hard to find SBCs with an operating temperature range of -40 to +85 C, and they're built to handle humidity. I've had good luck with Advantech devices; Diamond Systems makes SBCs with data acquisition systems built-in which might come in handy for your application.

    Whatever SBC you get, be sure to pair it with an extended (aka industrial) temperature range boot device. Industrial CompactFlash cards are a good choice here. Finally, put the works in a good enclosure. Diamond Systems makes a good one for their SBCs; TRI-M has a good generic PC/104 enclosure.
  16. Re:On a related subject... on WxPython in Action · · Score: 1

    You might want to take a look at pyFLTK, based on the excellent FLTK (Fast Light Toolkit). FLTK's got very good OpenGL support, and from the pyFLTK Examples page it looks as though pyFLTK supports it as well.

    REALbasic is really shaping up to fill the niche left by the demise of Visual Basic 6. I haven't played with this feature extensively yet but it does have an office automation feature to handle Excel, Word, etc. Might be worth a look.

  18. Re:Obvious. on The Man Who Said No to Wal-Mart · · Score: 5, Interesting
    I'm sure I'll get flamed for this, but...depending on the setting, Mom and Pop stores aren't always a better choice for the community than a Walmart.

    Where I grew up (very small town, extremely isolated in the middle of nowhere), the local stores could gouge you stupid because it just wasn't worth a 90 minute drive to the nearest other town for better prices on groceries, or a five hour drive for better prices on appliances to the nearest "big city". Granted being in the middle of nowhere meant that the local stores had to contend with high supplier costs, but somehow $8 for 2 litres of Pepsi still seems excessive. The owners were the first to cheerfully admit that they were getting filthy rich off what amounted to a monopoly in this one-horse town.

    Then along came Walmart in the next town over. Suddenly the local outfits found themselves having to be competitive. It was still a 90 minute drive so they could charge a slight premium for convenience, but they couldn't get away with the markups they used to enjoy. Today the local grocery store still enjoys a monopoly of sorts in the town, and was able to open a brand new megastore. They just can't charge whatever they feel like anymore.

    I'm not saying Walmart's a saint, I'm well aware of the fact that they aren't. I'm just suggesting that it's not always the bad guy, nor is the local non-chain always the good guy. Ok, let the outraged flames commence. :)

    Ditto for WiFi and Bluetooth-I know of at least one BlackBerry user in the Army that had to move heaven and earth to get his inside.

    Usually, as long as you can show all that functionality you paid for can be disabled, they'll let you in...which then brings up the whole "Why bother?" question for me. :)
  20. Re:BitMover is in the right on No More BitKeeper Linux · · Score: 1

    I'd also add that I'd expect that any organization calling itself Open Source Development Labs should be taken to task by the FOSS community at large if they tried to tell an employee what they could/could not do during their own time. Wouldn't that be antithetical to their entire mission?

    BitMover can yank the free version if they want, it's their product and their right. But I don't see how OSDL should or even could regulate what their employees do outside the office.

  22. Re:Prolly won't work on Wireless Security By The Gallon · · Score: 1

    Something like that. :)

    I wanted to try and keep the signal leakage down, and I was worried that the lid would keep open a crack with the power cable sticking out of it. Weighting it helped keep the lid tight and (I think) helped reduce leakage through the toolbox.
  23. Prolly won't work on Wireless Security By The Gallon · · Score: 1

    There'll be some attenuation, sure, but don't forget the signal you get after going through one of these painted-on Faraday cages also depends on how strong the original signal was. Even if you put steel plates up if you blast the signal strongly enough something will get through.

    Case in point: a few weeks ago I took a regular ol' D-Link 802.11b router, took its antenna off, and threw it in a steel toolbox. Closed the lid, weighed it down. I was still able to get a halfway decent signal from more than 20 feet away.

    Yes, there would be some leakage around the edges of the toolbox, especially around the router's power cable. Still, I think that one of these rooms would fare worse.
  24. H1-B going for green card tomorrow on Debugging Indian Computer Programmers · · Score: 3, Insightful

    As somebody on the H1-B going to get his green card tomorrow morning, I feel like I should throw my $.02 Canadian in.

    Others in this thread posted that H1-B != immigrant, and they're right to say so. But the H1-B visa lets you have "dual intent," which is when you're here not as an immigrant but allowed to pursue immigrant status. That's the main reason I switched from the NAFTA TN-1 visa, which doesn't allow this. So while technically your status says you aren't an immigrant, you can still have every intention of immigrating under the H1-B program.

    I don't send the money I make out of the country, not unless you count me paying off my old car in Canada, now thankfully done, or making payments on my student loans. Other than that what I make stays in this country: paying others, investing, etc. I think I have to pay all the same fees a "normal" person does: Social Security, Medicare, income tax, and all that good stuff. Even when I bought a retirement present for the old man, it was from an American retailer and shipped back to the old country.

    I like to think I contribute something to the country and the people that have been so good to me over the past 5+ years I've been here. I've had more than a couple of offers to go back home, some more lucrative than what I have here, but here I feel like I'm doing some good.

    Anyway that's enough out of me. To any and all Americans reading, let me just add...thanks for the opportunity. Nice place you have here. :)
