  1. How can you not read a Wordstar 1.0 floppy? on Why Steve Albini Still Prefers Analog Tape · · Score: 1

    All these mechanisms have their limitations, and if you've ever tried to do real-world data collection from a wide-ranging group of people who have data in random formats, it's a mess. People used to send me tapes in VMS Backup format, or with a duct-tape label indicating which tape it was and an Nth-generation photocopy of what some of the fields on the tape were, or 8" floppies in RSX-11 format. I've got useful data on Sun cartridge tapes, ZIP drives, and several generations of floppies, not that I've got readers for all of them (or ways to plug the readers into my current computers.) My department at $DAYJOB had the last 800-bpi 9-track tape drive in my building 20+ years ago; these days I don't know anybody with a 1600- or 6250-bpi tape drive, though I suspect there are some here in Silicon Valley besides the Computer History Museum and Digibarn.

    Data formats rot. Hardware formats rot. The only way to keep the stuff is to keep copying onto newer media, and keep extensive documentation.

  2. X-Don't-Wiretap-Me-,-Bro!: on Time For X-No-Wiretap HTTP Header? · · Score: 1

    Yeah, that'll work.

    Protecting your messages with crypto is a start, and using traffic mixers like Tor and Mixmaster to resist traffic analysis, but it's a hard job when the Bad Guys have Moore's Law on their side and unlimited unaccountable budgets and politicians who want to keep it that way.

  3. Big Government is a Right-Winger thing on Time For X-No-Wiretap HTTP Header? · · Score: 1

    Look, you right-wing trolls like to talk about how liberals and progressives want big government, but we're dealing with Bush's Homeland Security Mafia here, and the right-wing Drug War, and the right-wing Big Military-Industrial-Complex which goes conquering other countries on behalf of Big Oil and Hating Foreigners. And you guys talk about "Intellectual Property" like it's as sacred a thing as owning real dirt property that we stole from the Indians, so the Copyright Police are as much your fault as they are the liberals' fault. And if Obama were actually a liberal, we'd have some Hopey Changey Stuff and the warrantless wiretappers and Gitmo torturers would be in jail, instead of him telling his Justice Department to defend the Bush Administration policies.

  4. You secure it with Crypto, not Guns. on Time For X-No-Wiretap HTTP Header? · · Score: 1

    You and your friends don't have enough guns to outgun the NSA (who are typically not armed), much less the FBI, Pentagon, and Copyright police. If you want your data not to get wiretapped, you need to use crypto, end-to-end, and use various traffic analysis obfuscation services in the middle, and get enough people doing it to have some actual cover traffic (because being the one person using an anonymity service doesn't do the job.)

  5. Re:1-6-11 vs. 1-4-8-11, B vs. G vs. N. on Bad Connections Dog Google's Mountain View Wi-Fi Network · · Score: 1

    1-4-8-11 is theoretically better for most people than 1-6-11, because you get more useful channels, but unfortunately that only works if you can get everybody to go along. In a business with one IT department you can do it; in an apartment complex with random people you can't stop people from randomly choosing 6. A couple of my neighbors are on 6, one's on 8, one's on 10, a couple of high-power 1s, and usually mine's the only one that goes to 11.

    If all of your equipment can support it, there's also slightly-illegal-in-US use of channel 13, or of course the 5 GHz band which has non-overlapping channels and usually nobody actually using it. (Unfortunately, while my router supports 5 GHz, it doesn't support using 2.4 and 5 simultaneously; I suppose I could drag out the old 2.4 travel hub and hang it off an Ethernet port for the older laptop to talk to and switch the rest to 5.)

  6. Misinterpretation *By Linux* on Misinterpretation of Standard Causing USB Disconnects On Resume In Linux · · Score: 2

    Unfortunately, the article's referring to the "misinterpretation" passively, not saying directly who the author is asserting misinterpreted the spec, but I think from context it seems to be saying "misinterpreted by Linux", as opposed to "misinterpreted by lots of cheapo USB devices". It's bad that Linux does that, but it's certainly easier to fix in one place in Linux than going out to lots of vendors putting out equipment with very low profit margins and hope they'll all do the right thing.

    I was also a bit confused as to when the article was referring to microseconds (s) vs. milliseconds (ms); I found it surprising that it seemed to be saying that most of the devices responded in under a microsecond, while others were over 10ms.

  7. Logging all queries on Florida Town Stores License Plate Camera Images For Ten Years · · Score: 1

    Obviously they'd be just fine with a process that logs all queries to the database, including who queried it and what they queried, and keeps that log for at least 10 years, and having regular audits of the log files? Because they're not doing anything wrong, so they totally shouldn't mind a bit, right?

  8. My current "Home Renovation" diet on Book Review: The Healthy Programmer · · Score: 1

    I've lost 10-12 pounds in the past month, mostly from lower calorie consumption, habit disruption, and moderate exercise increase. I live in a condo, and the condo board finally got around to doing the roof replacement they'd been planning for a while (with nearly no notice), which meant that we could do the ceiling sheetrock repair that the place has needed after a few years of minor roof leaks, and replace the rug which had long since warn out, and since the ceiling was going to need to be repainted, it was really time to repaint the rest of the place. So we moved all our furniture and junk into storage where we can sort through it, and started talking to contractors, floor people, sheetrock fixers, and trying dozens of different samples of paint that aren't quite the same color of almost-white as the wall [long rant deleted.]

    The TV's packed safely away facing a wall, so we're not watching it, and the couch is also packed away. The dinner table's temporarily replaced by a tray table and a couple of chairs. Half the weight loss probably happened the first week, hauling boxes around, but I seem to be eating a good bit less in general, and we've been more likely to have a salad or some hard-boiled eggs at home than to go out for lunch or dinner.

    The classic book "The Hacker's Diet - Weight Loss through Stress and Poor Nutrition" really got a lot of things right...

  9. Re:OBAMA STATEMENT VALID on Obama on Surveillance: "We Can and Must Be More Transparent" · · Score: 1

    Well, yeah. When he said "We need to be more transparent", he meant the American public needs to be more transparent so they can eavesdrop on us without having to spend so much money or violate so many laws.

    But Louis Freeh's FBI under Clinton didn't want Americans to be able to use encryption, and Bush's Homeland Security mafiosi wanted to wiretap us without warrants and got a Patriot Act wishlist draft handed to Congress within a week of 9/11, so it's not like there's much different about President Obama except whether he sounds like he feels guilty about getting caught. (Too bad - Senator Obama and Candidate Obama had been pretty decent on privacy issues.)

  10. 1-6-11 vs. 1-4-8-11, B vs. G vs. N. on Bad Connections Dog Google's Mountain View Wi-Fi Network · · Score: 1

    The most common channel choice recommendation is to only use channels 1, 6, and 11, for entirely non-overlapping operations. There's an alternative, 1-4-8-11, that's pretty low interference. Back when people used 802.11b, or most of the time with 802.11g, I didn't get much interference from my neighbors, especially since I picked a relatively quiet channel. But when 802.11n came out, I started getting a lot more interference. Part of that was just changes in what channels they were using, so that helped a bit, but eventually I bit the bullet and got my own 802.11n router (and was startled to find that it didn't do IPv6 yet.)

    Google, of course, is smart enough to have allocated channels in some optimal manner to reduce interference between their equipment; I don't know how much they paid attention to what other users were doing.

  11. Re:SDHC vs. USB or SSD on Hybrid Hard Drives Just Need 8GB of NAND · · Score: 1

    By the way, the reason I used an SDHC instead of a USB stick was mainly because the SD slot fits inside the laptop body, while a USB drive would have stuck out and I'd have had to remove it every time I put the laptop into its bag, plus I often needed both USB slots. For a desktop box the USB would win, or an internal SSD hanging off a SATA port, which most motherboards seem to have spares of.

  12. Hybrid Drives vs. OS Caching on Hybrid Hard Drives Just Need 8GB of NAND · · Score: 1

    A hybrid drive builds the caching function into the drive, as opposed to having the OS keep track of disk-vs-flash-vs-RAM and doing its own caching. So yeah, it's possible that if the hybrid drive is badly designed, a failure in the flash could result in losing access to the data on the spinning drive as well; you'd hope they'd avoid that.

    And yeah, of course you need backups. A bullet-proof hybrid drive design or OS caching algorithm isn't going to stop you from scribbling the wrong stuff onto the drive.

  13. Obsolescence dwarfs failures - Moore's Law on Hybrid Hard Drives Just Need 8GB of NAND · · Score: 1

    30 years ago, disk failures were a serious problem. 20 years ago they were still a problem. By 10 years ago, Moore's Law was cranking disk price/performance so fast that your disk had a 99.99% chance of being boringly small and obsolete long before it failed, and it's still the same. Yes, that 8GB SSD cache for your 1TB drive may fail in 5 years, but 5 years from now you'll have junked that wimpy drive and replaced it with a cheaper 128GB cache and 8TB drive.

  14. Fast vs. Slow vs. Hybrid Storage Needs on Hybrid Hard Drives Just Need 8GB of NAND · · Score: 1

    Yes, SSDs are faster and more expensive. The obvious approach is to have an SSD that's big enough for the stuff you use all the time, and a spinny drive to handle the bulk storage. Hybrid drives (which were the original topic here) have a spinny drive with a small flash cache, so you can do most of your I/O from flash and it can keep the mechanical drive updated at its leisure, so your CPU isn't stuck waiting for rotation latency.

    But you could do just as well by having an operating system doing the caching in separate storage; hybrid drives are mainly a win for people with lame OS's. (Oh, wait, most OS's are a bit lame about this.) MS's Readyboost stuff was supposed to be a big win; I've only tried it using an SDHC flash card, which might be on a slow bus, instead of an SSD that probably has a faster connection, but I haven't seen a significant speedup when I use it.

    My guess is the opposite - you'll probably notice the difference in resolution more for black on white text than for photos.

  16. Early laser printers on Are We At the Limit of Screen Resolution Improvements? · · Score: 1

    My first laser printer was an Imagen wet-process printer (based on the printer mechanism of a Canon copier engine.) 240dpi, with a liquid toner that was pretty much carbon black dissolved in kerosene. It didn't need anti-aliasing to smooth out jaggies :-)

  17. 4K Resolution - TVs driving PC Monitor Market on Are We At the Limit of Screen Resolution Improvements? · · Score: 1

    Until we see a lot of 4K TVs out there, we aren't going to get cheap 4K PC monitors. As far as high enough quality for work goes, color resolution doesn't matter to me; pixel count and size do. (And as for responsiveness for gaming goes, as long as the screen isn't actually flickering, Nethack isn't bothered by 50ms latency.)

    Having finally acquired an HDTV this year, I've found that it's nice to have a monitor that is in the same aspect ratio as movies so I don't need to black-box or have the sides cut off, but there aren't that many movies that really need the extra resolution as opposed to the correct aspect ratio. Regular TV programming cares even less about resolution; either the writing's good or it's not, and HDTV won't fix bad writing, and talking heads are either saying something sensible or blathering. Sports and nature programming are exceptions to that - being able to see a moving hockey puck or tennis ball better helps a lot, and wildlife pictures on National Geographic do look a lot better if you've got hi-def.

  18. Looking as good as paper on Are We At the Limit of Screen Resolution Improvements? · · Score: 1

    Yeah, for a 24" monitor I'd be happy to have 300dpi, because I want to be able to read my computer as easily as I read paper. 200x200 is a standard-mode Group 3 Fax machine resolution, and while it's a lot less ugly than the 100x200 mode, it's still ugly (though of course your monitor doesn't have the vertical sloppiness that mechanically-driven paper printer rollers have and the fuzzy pixels of thermal paper.)

    If you're watching movies, or even still pictures, resolution doesn't matter as much, because your eyes will fix that stuff. But when I'm using a computer monitor, I usually want to read lots of text. For that you need actual pixels, even if most of them are running in 1-bit color, or 4-bit color so you can do better navigation clues.

  19. Phone Screen Resolution for Old Fogies on Are We At the Limit of Screen Resolution Improvements? · · Score: 1

    At $DAYJOB, we're always getting lots of company propaganda about "Don't Text While Driving". Not a problem for me - I can't do texting without my reading glasses, and I can't drive with my reading glasses on. And the [expletive-deleted] HTC-flavored Android texting application may look pretty, but it doesn't let me change the font size, and doesn't let me do the two-finger stretch thing, and doesn't even do a decent job of adapting to landscape-more screen orientation. Yes, the Google-provided keyboard thing with it has a little button you can press to do speech-to-text, if you've got your reading glasses on so you can not only press the [expletive-deleted] little button and then read the results it got back to be sure they're not hopelessly garbled, but that doesn't really help.

    Yes, a higher resolution screen helps make the text clearer. But what I really want is a phone that can be controlled entirely by voice for most common applications, like texting. The Bluetooth connection to my car supports voice dialing; why can't the phone support at least voice-controlled reception of text messages?

  22. What Sourcefire Currently Does on Cisco To Acquire Sourcefire For $2.7 Billion · · Score: 3, Informative

    Disclaimer: At $DAYJOB, I work on managed security services using Sourcefire, but this is my own personal commentary, not that of my employer.

    Sourcefire's primary product line takes Snort, wraps it in hardware appliances, and adds a lot of management tools that you can use in an enterprise or managed services environment. This past year, they've added a firewall capability to compete with Palo Alto* and the UTM vendors like Fortinet - in addition to basic firewall support they've got application identification, so you can do things like allow users to read Facebook but block Facebook games, and you can also do things like URL censorship and known-bad-site blacklisting. They've also been buying up other companies like ClamAV and Immunet, so they've got feeds of malware site identification, and are starting to integrate that with the firewall/IDS as well as continuing the host-based versions.

    Cisco's IDS/IPS offers have been pretty lame the past few years, but they've got decent firewalls, so we'll see how those product lines play against each other. (I don't know what Cisco's doing in Anti-virus and cloud malware detection these days.)

    Sourcefire's hardware at the low end is basically Linux box appliances, and at the high end they're doing a bunch of hardware acceleration. Their largest single box will handle 10 Gbps of inspection, and they can cluster up to four of those to support 40 Gbps. There's not much competition up at the high end - McAfee may have come out with a 10 Gbps follower to their previous 5 Gbps box, and Juniper has some boxes that are bigger but are mainly firewalls with some limited IPS capability. If you've got existing Snort on Linux, Sourcefire does also sell connection tools to integrate with their management systems.

    *The term "Next Generation Firewall" means "whatever Palo Alto's marketing says it means", but is at least firewall plus application identification. I've heard that Cisco tried to buy Palo Alto last year.

  25. Crypto Weaknesses of Dropbox on Dropbox Wants To Replace Your Hard Disk · · Score: 0

    Dropbox encrypts each of the steps - your PC to their server, their server to their storage, their storage back to your PC/phone/etc. That's very different from user-controlled encryption, where you've got the keys, Dropbox only ever gets cyphertext (which it might wrap another layer around for extra security), and if the FBI hands them a warrant, they've got nothing useful to hand over.

    It's somewhat of a business model problem for them, though - if they want to start adding lots of extra features, like Evernote's conversion of data between formats (OCR scanned pictures, read email via text-to-speech, etc.), they need access to the plaintext, but I have no intention of outsourcing my plaintext.
