  1. Small Faraday Cage? on The Geek Group's Hacker-Oriented High Voltage Lab In Michigan Damaged by Fire · · Score: 1

    Seems like a small Faraday cage around each battery powered smoke detector would work. I have experience with high powered RF (VHF through 2.4GHz, 125W of emitted RF power) and smoke detectors never had a problems with this equipment.

  2. Data May Be *Safer* Overseas on Ask Slashdot: Explaining Cloud Privacy Risks To K-12 Teachers? · · Score: 3, Insightful

    What gives you the idea that data is safer stored within the US? In reality, I think it is less likely to fall into the 'wrong hands' (someone who wants to embarrass or blackmail your child later in life) stored overseas.

  3. Re:Can you go paperless? on Ask Slashdot: How To Go Paperless At Home? · · Score: 1

    I've used the Fujitsu Snapscan S1500 for the past 18 months and I cannot think of enough good things to say about the hardware. Using the included ScanSnap Organizer, I throw a bill or statement on the machine and it's scanned in seconds. The software uses AbbeyFine OCR to create a "backing" of searchable text in the PDF; the scanned image is presented for viewing and printing. The OCR works very well for printed documents, rather poorly for handwriting. It also has the ability to put the scanned document into a folder based on keywords, e.g. 'Sprint', 'Chase', etc. When I want to find specific documents, it is far faster to type in 'Chase 2011' to get all my bank statements from last year than to search through the files.

    Keeping my life on the hard drive means that I have to use special care in backups, which I take using USB hard drives. The usual: rotating media, off site, annual benchmark that lives for years...

    I am much more comfortable now that I will be able to produce receipts for the IRS on request than I was with a paper filing system. This is far less work for me and I feel much better about finding things. Documents are stored in searchable PDF; no worries if AbbeyFine or ScanSnap go out of business.

    After seeing the recommendation here, I need to check into Yojimbo or Evernote.

  4. ARM Needs Cache on Apple Intern Spent 12 Weeks Porting Mac OS X To ARM · · Score: 1

    My company has run ARM9 embedded products since 2004. And since 2004 the ARM processors have always been s..l..o..w.. due to a minuscule L1 cache and no opportunity or support for L2 or L3. Moving the identical applications to Linux x86 PCs, our prior estimate was that the ARM9 processors were 25X slower, clock for clock, than then-current Xeon processors. That turns out to have been wildly optimistic. Running identical code, the Xeons were at least 100X faster than the ARM9s: adjusted for clock rate (533MHz ARM9 vs. 1.8GHz Xeon) we could easily run more than 100X simultaneous processes on the Xeon that contained the entirety of the ARM9 code, barely blipping the CPU load. We ended up being limited by the maximum number of multicast addresses Linux supports.

    We were running VxWorks 5.6 on the ARM9 processors and Centos 5.4 Linux on the Xeons.

  6. Why Keep Smallpox? on The $443 Million Smallpox Vaccine That Nobody Needs · · Score: 1

    Given that we have the DNA sequence for smallpox, can someone please tell me why, oh why, do we keep this deadly virus around AT ALL? I was vaccinated for smallpox, but my two younger brothers lack the tell-tale scar. Given that immunity fades after between 3 and 50 years, with 3 to 5 years being typical, any release of smallpox into the wild would have devastating worldwide consequences. So, tell me again why we keep live virus in the fridge?

  7. Re:When are multiple cores going to help me? on First 16-Core Opteron Chips Arrive From AMD · · Score: 1

    I run a recent Dell T3500, 24GB RAM and dual GTS450 graphics cards. The extra cores help a lot with Adobe After Effects. A. LOT. Not so much with Adobe Premiere, because you get far more bang for your buck with a medium-to-high end NVIDIA graphics card: Premiere makes excellent use of CUDA, particularly for encoding. (By default, Premiere will only see and use "pro" cards: Quadro, Fermi, Tesla. There is an easy configuration hack that lets it use any 200 series or better card. My GTS450 encodes full 1080 HD in real-time. ) There is a caveat there: only for encoding in the foreground, and it only uses a single NVIDIA graphics card: SLI does not matter.

    I find it strange the the foreground encoding uses GPU acceleration, but batch encoding does not. So the extra cores would help you there, too.

    In my programming, (large scale network simulation, real-time audio processing) any cores beyond 2 do little to nothing. When I re-compile the latest version of Boost, the extra cores substantially speed the build, but this is something I only do 2-3X per year.

  8. The right tool for the job on What's Keeping You On Windows? · · Score: 1

  9. Re:Support them from your own money on How Can I Justify Using Red Hat When CentOS Exists? · · Score: 1

    CentOS lacks the rather worthless Red Hat support and the obnoxious Red Hat license, "If ANY Red Hat box is under support at your company, then ALL Red Hat boxes must be under support."

    We started running Red Hat in 2004, and included a Red Hat license with every Dell server we bought - dozens. That slowed down after we had tried to use Red Hat support a few times: if you are competent to administer a production server then Red Hat support is not helpful. So we went to just specifying Red Hat for servers running software that requires Red Hat (or such) for support, e.g. Oracle. We left our existing Red Hat licenses in place and continued to pay for support on the production servers; we let support on the pre-production staging servers lapse.

    In the last 18 months, Red Hat has been pushing "all-or-none" support rather obnoxiously. So we have been actively pruning Red Hat out of the organization down to only those servers that require it for the other vendor's support contract.

  10. Re:I've said it a hundred times... on TSA's VIPR Bites Rail, Bus, and Ferry Passengers · · Score: 1

    As much as I detest TSA policies, violent resistance to TSA personnel is NOT the answer. These are blue collar folks who have a job. Violence against them is wrong. Civil disobedience, like everyone requesting a Freedom Fondle (TM) rather than go through the body scanner is more likely to be effective (by jamming up the lines) and does not visit violence on those who deserve no such thing.

  11. Re:I'd say that's "mostly" true. on Linux Foundation Releases Document On UEFI Secure Boot · · Score: 2

    My first programming on a 286 was using DEBUG to create .COM files. I've written AIX device drivers and have used Linux since 1992 and compiled plenty of kernels as well as kernel modules. I work heavily with embedded software.

    Despite this I find setting up WIFI under Linux a huge PITA. I normally end up using NDISwrapper. The whole thing reminds me of Winmodems, only I could readily purchase a hardware modem that I knew would do the job. With WIFI vendors continually changing chipsets and firmware versions without changing the model number, buying a "known good" WIFI card is a crapshoot.

  13. Re:Self-important judiciary on Sony Wins Restraining Order Against Geohot · · Score: 2

    To receive injunctive relief, the moving party must demonstrate "It has at least a reasonable likelihood of success on the merits." This wording is part one of a four part test on when injunctive relief may be granted, as laid out by the U.S. Supreme Court in Rizzo v. Goode. See the first Google hit for "likely to succeed on the merits."

    Use of the wording is not a show of bias, but the judge's way of referencing that test to show that she operated within her judicial discretion. Be careful throwing around phrases like "bias.. ignorance of the facts, or both" when your comment itself demonstrates, well, both. There are bad judges like there are bad programmers, bad mathematicians, and bad engineers but accusing someone of criminal misconduct due to your own ignorance is irresponsible.

  17. Cheating In Upper Level Engineering Courses on How Easy Is It To Cheat In CS? · · Score: 1

    In many of the engineering courses I took, there was a choice to get a sold A or to learn the material. Those wanting the best grade got the old tests from student organizations or friends. It's difficult to compete with students who already have the full test. Granted, they don't learn much from the course but they end up with the better GPA. Now, this could have been helped had the professors not been so lazy as to recycle material and/or if the professors had given out all their old material at the beginning of class, which some did.

    There were whole areas of EE in which I didn't even take classes because the professor who taught them gave the exact same test every semester and only graded the answer in the box. This is for both undergrad and graduate courses.

  20. Re:Firefox Memory Leaks, C++ Memory Leaks on Comparing Memory Usage of Firefox 2 vs 3 · · Score: 2, Interesting

    I'm the lead for a group of over 20 engineers and programmers that produces public safety communications equipment and have direct experience with memory leaks large scale C++ projects AND Firefox. The system we sell includes embedded devices, a Linux/Oracle/Apache server for management, and management terminals. Management and monitoring is done via web browser, either on Windows or Linux. We officially support both Firefox and IE, and both leak memory. We strictly control what is installed on the management PCs - no browsers extensions, no ActiveX components, no Firefox Ad-ons. Typical usage is to open the browser and monitor one page continuously for weeks until an alarm is shown.

    Let me be clear, both Firefox and IE leak memory so badly that even on management PC with 2GB of RAM we have to require the end user to restart the browser every week. We are monitoring FF3 and looking forward to reduced memory leakage. In the referenced article it discusses reducing memory fragmentation. OK, that's a worthy goal but first fix the memory leaks. Memory fragmentation and memory leaks are related, but different beasties. A memory leak almost always results in fragmentation, but fragmentation can happen simply from an unfortunate memory allocation/deallocation pattern.

    Regarding C++ and memory leaks: over 2 1/2 years we've worked on the embedded code, which is pure C++, we have hunted exactly one memory leak. And that leak turned out to be from the OS. We use Boost smart pointers, RAII, exceptions, and exception safe code. We have no trouble with leaks or fragmentation, despite a fairly high turnover rate and a customer base that would quickly notice memory leaks requiring reboot of the embedded devices.

How about digging up Lincoln's tomb - it could tell us more about how he lived and died. If you find these examples offensive consider this:

    Time after time, from the Incas, the Mayas, the Egyptians, American Indians, etc. entire cities or societies worked for a generation to ensure that their royalty, leaders, or god-kings could rest forever undisturbed.

  25. PHP == "Perl Lite" on Larry Wall on Perl 6 · · Score: 1

    A year ago, a friend asked me to help write a web page for her softball league, to track team rosters, etc. Having done a couple of web pages in Perl, and with about 10 years of Perl experience, it was my first thought. However, I'd been hearing a lot about PHP. So I read a PHP book and did a bit of experimenting.

    To my mind, PHP is "Perl Lite". Yes, its nice to embed functionality directly in the page. But PHP is far too watered down in capabilities, and lacks CPAN. If you want markup functionality, give Template Toolkit a try. If you don't like TT, try Mason. Unless you want a canned Wiki that's easy to customize, I don't see a reason for PHP.
