  1. Different Navigation Styles for Different Readers on Top Ten Web-Design Mistakes of 2002 · · Score: 2
    Different people have different goals and different thought processes. Some web designers think that a layout that makes sense to them, when they've got the entire site map in their head and know what all the parts mean, is useful to other people. A few of those designers are even correct, but mostly for small simple sites without automation :-) In general, some people who make badly designed web sites know and don't care, but most bad web designers don't know that they're bad, or who they're bad for, but they do care. A site map is really easy to add to any site that isn't totally badly designed, and doesn't interfere with a good site. You might as well use one, in case you're one of those bad web site designers who doesn't know it.

    Site maps are useful for some readers, search engines are useful for other readers, good well-designed links are best, good FAQs are useful for other readers. It's obvious that a good search engine is hard to implement, but if you make your pages easily searchable by Google, that's at least a start.

  2. Do they still Not Get It? on Is the New Microsoft Office Really Open? · · Score: 2

    " But this format will (of course) only represent the appearance, not any structure." WHAT!?!?! Do they still not bloody get the bloody concept, or are they deliberately trying to make interoperability unusable? They did this in earlier versions of Office with their save-as-html modes, which did stupid things like saving a "Header Type 2" as "14-point-boldface-text" or whatever your current style was rather than saving it as an HTML "H2", but at that point it could be attributed to stupidity and/or incompetence, since some people think for some reason that HTML is an appearance description language rather than an specific implementation instance of a content description metalanguage, which is a bit too abstract for some people. But XML is much more explicit about being a content description metalanguage, and if you've got enough of a clue about it to output your material as XML, you've got to get that much of the concept. I'd attribute this one to malice.

  3. Upload cap or Download cap? on OptimumOnline Bans uploads to P2P networks · · Score: 2
    Is the cap on your upload or your download? Many of the US cable modem companies cap everybody's upload at 128kbps (if their equipment is new enough) or something like 384-768 with older hardware, so a 128kbps cap is basically no change.

    Capping your *download* speeds to 128kbps would get your attention, though :-) Some cable companies, who are either "ahead of the curve" or "even more terminally clueless than most about why people buy broadband", have monthly download quotas of a couple of GB and drop your bandwidth to 56kbps or so once you exceed them. That's fine for regular web viewing, probably marginal for average Napster use, and totally useless if you want to download the latest Linux release. (On the other hand, some cable companies start surcharging you by the GB if you exceed the limit, so you can end up with megabuck charges if you weren't paying attention; I'd rather get slowed down than risk that.)

  4. That's more like 15000 feet on OptimumOnline Bans uploads to P2P networks · · Score: 2
    DSL is available in a fairly high fraction of non-rural residences in the US; your distance from the telco office determines what speeds you can get, and it of course depends on what DSL technology is being used, but typical limits are 12-18000 feet for 384kbps or various ADSL speeds, and about 30000 feet for IDSL (which uses ISDN technology, so it's a boring 128/144kbps, but better than modems.) If you want the newer up-to-8Mbps DSL flavors, you need to be much closer, and there are a lot fewer POPs supporting, and the pricing is usually a lot higher.

    I'm getting about 800-900kbps ADSL at a distance I've been told is somewhere between 12000 and 16000 feet, depending on who measured it (I think it's really about 12-14000 feet but bad wiring...). A few years ago, I had 384kbps SDSL here, but 768kbps SDSL didn't work.

    The main problem with 127.0.0.1 is that if you're also running a real web server on your machine, the requests for blocked sites will be sent to it, so your system will have to respond in some appropriate manner, and your browser will have to display the response appropriately. Some operating systems don't seem to have the clue that 127.0.0.2 is different from 127.0.0.1 :-) I haven't installed a web server on my main work machine since it got upgraded (?) to Win2000, but older Windows used to be a bit fuzzy about the distinction.

  9. Why there's a Fifth Amendment in the US on FBI To Use Ad Banners to Find Criminals · · Score: 3, Informative
    Eighteenth-Century Britain had a popular investigative technique called "We'll keep torturing you until you confess". One of the traditional methods was to keep piling heavy rocks on the accused until he either confessed or died; I've forgotten which defiant holdout's last words were "More weight!". This sort of thing wasn't a new invention of the time, and the Brits weren't the only people who used it (nobody expected the Spanish Inquisition...), and it was more popularly used on political enemies, accused heretics and witches, and people who had "accomplices" on whom it was desired that they should rat, rather than on common criminals, who usually had the sense to confess or frame someone else, especially since they were often actually guilty of something. That's the main reason for the Fifth Amendment. That doesn't mean we've totally abandoned the practice - cops still beat people up or threaten to do things to them or their families - but it's certainly reduced the problem, and at least it's a rare illegal event in the back room rather than a common event on the courtroom floor.


    American jurisprudence also has a bunch of 1960s practices like the Exclusionary Rule and the Miranda Warning which say that courts can't admit evidence that was acquired improperly, whether it was from beating prisoners until they confess, illegally searching homes without warrants, or getting warrants by lying to judges, or lying to prisoners about the law when they don't have lawyers to advise them. Again, it didn't totally eliminate abuses, but the traditional example for its effectiveness is that the year before the Exclusionary Rule, police in New York City didn't bother getting any search warrants - they just illegally searched anybody and any place they wanted to, while the year after the rule, they almost always got warrants when they needed them (even if they still lied about their evidence on occasion.)

I later upgraded the box from 24MB to 192MB, and it worked a bit better :-) One of the other machines got upgraded to 640MB, because it seemed like that ought to be enough memory for anybody.


    As somebody else replied, this level of memory bloat is pretty recent - for most kinds of software, you shouldn't be designing it to require a latest-model desktop power box, but a two-year-old laptop, which has a lot less spare resources. That way it will run well for everybody and really rock on high-end machines. Some applications are obvious exceptions, like games, and scientific/engineering numbercrunching.

    Netscape 6 was bad, bad, mindbogglingly amazingly bad, at least on a machine with only 24MB of RAM. 6.1 or 6.2 was much closer to usable, at least on my machines with 64MB, but by then Mozilla was working adequately. If Netscape 7.0 is fast, a large part of it is probably from using lots of memory to accelerate other functions.

    I'm now using Phoenix 0.5, which came out just recently, and it's quite toasty - I think it's ready to replace Mozilla as my main browser. The main plugins work (I'd had trouble getting them installed on 0.3 and 0.4) and it's very very fast, especially since I set the startup delay to 0 (default is 1200ms, which lets it recover from slow-loading graphics that would otherwise force redraws.) The Google-search-bar extension is really convenient, though I gather than newer Mozillas also have it. I'm normally no fan of themes (why clutter up the GUI at the cost of making it larger and slower?), but the "LittlePhoenix 1.3" theme has icons that are enough smaller that I can reclaim significant screen space, and the "Linky" extension has been a good way to handle pages with lots of links (e.g. letting you leech all the pictures into a separate window or tab, or examine a page by grabbing all the URLs on it into a tab, which can be cleaner than View Source for some ugly web pages.)

  16. Unused Wavelengths, not just fibers. on Dark Fiber: A Case In Point · · Score: 2
    Several people have pointed out that the cost of laying a big bundle of fiber isn't much different from laying a single pair of fibers, and it's dumb to use expensive optical amplifiers on fibers you don't need to use yet, plus expensive optical muxes and line-terminating equipment at the ends, especially when a pair of fibers can run up to 160 wavelengths, of up to OC192. One reason it makes financial sense to roll out lots of fibers, especially in metropolitan areas, is that you get much more flexibility about customer locations, and as long as you're not exceeding distance limitations (which depend on the type of signals you're sending) it's a lot cheaper to run extra fiber and use it inefficiently, because fiber splices are much cheaper than optical amplifiers or active electronics or wavelength-division multiplexers. It's also a lot easier for a carrier to handle selling to multiple customers (who are often other carriers, not just end-users) if you can give them their own fiber rather than wavelengths. For long-haul routes, or big metro rings, it's worth putting more active equipment in and using more wavelengths.

    Another issue is that much of the Oregon build-out happened late in the boom - if you look at the Boston-NewYork-WashingtonDC routes, which were developed earlier, you'll find that there's less multiplexing and more sale of individual whole fibers, because the equipment costs were higher, but they did a Moore's Law type crash dive during the late 90s and early 00s that Oregon benefitted more from.

    Meanwhile, if you're trying to get a data feed to every lottery terminal in Oregon, you don't care about 160-wavelength x 10Gbps OC192 fibers - you care about getting 4kbps worth of data on whatever kind of copper wire or wireless goes out to the convenience store, and doing the protocol conversion because lottery terminals still speak X.25 and nobody wants to pay the capital costs to teach the things IP :-)

  18. Periodic Re-Copying is the only viable method on Large IDE Drives as Long-Term Archival Media? · · Score: 2
    *Everything* is a horrible archival medium. The IDE drives will support you just fine while you're starting to address the hard problems. Don't bother with 100MB-Ether if you can conveniently do GigE though - it's gotten really cheap.
    • Data format rot and hardware medium support rot will kill your data much more thoroughly than equipment failure will.
    • Only one of the writable-DVD formats will still be readable in 5 years - I don't know which one, because it will be a market support issue, not a hardware reliability issue. Copy protection may make that worse.
    • The file system format your data is stored in won't be readable by Windows in five years, though it will probably be readble by Linux.
    • Any data format that isn't basically text will be obsolete - HTML and XML will be readable, but word processor files will be almost totally useless, and at least half of your non-text-like database formats will be mostly useless. You can keep a copy of MSWord and Excel, and the original CDROM installation media, but it won't run on Windows 2007XYZ, and your WordStar 5.25" floppies aren't much use today either. Closed-source will rot faster than open-source, but both will rot eventually.
    • That 6GB disk drive you bought three years ago isn't worth using, but the data fits nicely in a corner on that $120 120GB drive you picked up last week. The 120GB drives will be pretty boring in 5 years, whether they're IDE or SCSI, but the data will fit nicely in a corner on the old 1TB drive you'll be using for spare storage in a couple of years or the newer 8GB drive, but you may have a bit of trouble reading those tiny little 8KB blocks from the wimpy 2MB cache.


    So yes, use some kind of IDE RAID system for your backups, and be sure to save some backup computers and operating systems every year or two to read the old disks.

    • Depending on how much of your data is files as opposed to databases, come up with some reasonable strategy for full and incremental backups, and what stays on-line, on-site-but-off-line, and off-site, and if possible, keep a computer off-site as well.
    • Keep a database of what you've got backed up, and where.
    • At least annually, copy at least some of your full backups from old disks to new ones, and depending on your incremental or journaling structure, maybe more than that.
    • Make ABSOLUTELY sure your financial people have their records in some format that's readable and usable, and review with them every year to make sure their backups are in a usable format. Audits of seven-year-old financial data are no fun even when you *can* find the supplies for /dev/iso-9000-clay-tablet-scriber and programs that read the old-format sound files to output carrier pigeon calls to /dev/audio.

  19. Controller technology vs. reliability on Large IDE Drives as Long-Term Archival Media? · · Score: 2
    Maybe you're buying good SCSI disks and el-cheapo IDE drives, but the real difference in them is the controller cards, not the disks themselves. If you're using the disks for archive, not for active use, they're not going to be under the same load or wear&tear as the primary service disks. And you're probably going to RAID-5 them anyway.

    The real problem isn't usually hardware rot - it's data format rot and interface standards rot. IDE is a bit tired, but it'll be supportable much longer than N-1 of the current DVD-R standards, so you probably want both. In my attic, I've got a probably-good 9-track backup tape of some of my early work, and some newer probably-good Sun cartridge tapes, and I might still have a Sun tape reader, if I can find a copy of SunOS 3.5 for my Sun-2 diskless workstation to bootstrap something to read it with....
