    So go to Sourceforge, set up a project, and build a nice SuperAlarmClock project; hook up a nice Shuttle PC with a TV/Tuner board, and you can have an
    • alarm clock
    • radio
    • cd/DVD player
    • mp3/ogg/whatever player
    • web browser

    In other words, don't whine about it, write some code!

    ... when the drives in a RAID set near their end of life: Given
    • the bathtub curve of disk failure rates, and
    • that a raid reconstruct can take about a day on a lot of RAID sets
    you can certainly have a second drive fail while another one is being reconstructed if all the drives in the RAID are near end of life. The only good way to prevent it is to intentionally fail & replace sufficiently old drives before they actually fail (i.e. before you start climbing the steep end of the "bathtub" curve).

    It can be hard to explain to a company with whom you have a maintenance contract that a drive needs to be replaced that hasn't actaully failed yet. I know one admin (honest, it isn't me!) who advocates pulling old drives from the raid set and dropping them on the floor a few times and then calling service to "schedule" thes replacements ;-).

  6. There was a really good LISA talk... on Tips for Increasing Server Availability? · · Score: 4, Interesting
    ... about this a few years back. I forget the guy's name; he was administering a site that did stock quotes with pretty graphs, etc. I suspect I don't remember all of his points anymore, but:
    • two (or more!) network feeds from different vendors, verify monthly that they don't have common routing the best you can (sometimes you end up sharing a fiber even though it doesn't look like it...). These various connections all come into your front-end service LAN (which is distinct from your back-end service LAN...)
    • redundant front end servers which have their own copies of static content and cache any active content from...
    • redundant back end servers that actualy do the active content, and keep any databases, etc. Use a separate LAN for the front-end/back-end connections so that traffic doesn't fight with the actual web service.
    • Backup power (UPS + generator) with regular tests. (test on one side of your redundant servers at a time, just in case...)
    • Log only raw IP's, have a backend system with a caching DNS setup where you do web reports. Do things like log file compression, reports, etc. on the back end server only.
    • tripwire all the config stuff against a tripwire database burned to CD-ROM.
    • update configs on a test server (you do have test servers, right?) when they're right update the tripwire stuff, build a new tripwire CDROM, then update the production boxes.
    • use a fast network-switch-style load balancer on the front. They also help defend your servers against certain DOS attacks, (I.e. SYN floods).
    • when things get busy, load your test servers with the latest production stuff, and bring them into the load balance pool. If it takes N servers to handle a given load, it takes N+1 or N+2 to dig back out of a hole, because the load has at least 1 server out of commission at a time...
    • use revision control (RCS, CVS, subversion, whatever) on your config files.
    • use rsync or some such to keep 2 copies of your version control, above.
    • make sure you can reproduce a front-end or back-end machine from media + revision control + backups in under an hour. Test this regularly with a test server.
    If you have a site whose content changes less frequently, (i.e. at most daily) burn the whole site to a CD-ROM or DVD-ROM image, and boot your webservers from CDROM, as well. Then if you blow a server, you can just slap the CD's/DVD's in another box and be back in business, and it's much harder to hack.

    Well, anyhow, those are my top N recommendations for a keeps-on-running web service configuration. I'm sure I'm overlooking some stuff, but that should head you in the right direction. And if it doesn't sound like a lot of work, you weren't paying attention...

  8. Re:co2 emissions from volcanos on Global Warming Past The Point of No Return · · Score: 1
    I'm not sure where the previous poster got his number, but according to the US DOE, in 2003 the US alone put out just over 6 Billion metric tons of CO2, which is 16 million metric tons/day, just from the USA and that was in 2003; the increase has been on the order of 13% per year...

    Oh, I see, you're reading his saying "Humans produce ... " as "Each human produces", hence the per-capita....

    Anyhow, his number is right for Humans (collectively) in the USA. it's probably off by a factor of 5 or 10 for the world as a whole...

    But then he was comparing humans (collectively) to volcanos (collectively), as far as I could tell.

  9. Re:Doom and Gloom on Global Warming Past The Point of No Return · · Score: 2, Informative
    According to USGS in Hawaii
    Kilauea volcano emits more than 700,000 tons of CO2 each year, less than 0.01% of the yearly global contribution by human sources. For some local perspective, this is about the same amount of CO2 as is emitted by 132,000 sport utility vehicles (there are 118,000 registered vehicles on the island).
    So that means for the island of Kilauea, Hawaii, USA, which I suspect has one of the highest volcano:human CO2 ratios, it's almost even. That is to say, humans on Kilauea are putting out approxomately as much C02 (just from their cars) as volcanos are.

    According to US DOE EIA

    U.S. greenhouse gas emissions in 2003 were ... 6,115.2 million metric tons carbon dioxide equivalent...
    So that's 6 billion metric tons of C02. There are about 1,500 active volcanos in the world, so if Kilauea is representative at 700,000 tons of C02, that makes about 1 Billion metric tons of C02 from volcanos.

    So that makes the volcanos:USA ratio about 1:6.

    Does that help clarify?

  11. Wrong answer.. on The Law of Unintended Consequences: Patents · · Score: 1
    Why doesn't the government do this?

    The government doesn't do this because our Congress-critters are completely beholden to big drug companies and insurance companies to fund their campaigns and political party infrastructure, and doing this would make a dent in the drug company and insurance company profits. This is, in general, the reason the Government doesn't commercialize inventions; business interests make sure Congress knows they'll lose campaign funding if they vote for such things, and companies sue for restraint of trade if government branches do compete with them.

    So no, the legal system is not amenable to this -- the legal system is amenable to the folks with the most cash.

  15. Re:What about software under older GPL? Re:Taxatio on GPL to be Modified to Penalize Patents and DRM · · Score: 1
    Virtually every large software company has patents on software. The world's largest software patentee, by far, is IBM - a strong Linux advocate.
    My suspicion is that, if IBM holds patents that threaten Free Software, RMS doesnt care if they're a strong Linux advocate -- he would rather force them to grant a license to all their software patents to any and all software released under the GPL. Which is how I suspect they'll phrase it -- by copying or using any GPL software, you agree to license all your software patents for use in other GPL software...

    So if you want to make commercial software companies pay for your patents, great, but if you want to use GPL software, you have to let other GPL software use your patents

  16. Re:Bring on the MS shills. on Microsoft Windows Media Player Encryption Hacked · · Score: 1

    So the reason that you don't hear about Linux "shills" is that there isn't any money to pay them [in the minds of those people who think people are being payed by Microsoft...].

    Of course, in actuality, organizations like Red Hat, SuSE, and the Free Software Foundation are every bit as capable of employing a shill as Microsoft is; as to whether any of those organizations actually do so, I will leave you to decide for yourself.

    I saw it.

    Just to pick one out-and-out lie from the general confusion of your posting:

    Excuse me, but the open-source community wrote Apache from standards they didn't write.
    Well, lets see, Apache was based on NCSA httpd, which was a rewrite of the original www consortium httpd, which was written originally by Tim Berners-Lee. (all of which were open source). Now lets look at the original HTTP protocol standard -- what do you know, the authors are Tim Berners-Lee, and R. Fielding, from UC Uvine. And look at the Apache core team -- Roy Fielding!

    So, in fact, the open source folks who wrote Apache and its predecesors are the folks who wrote the standards.

    So as I posted on your site, the above statment is downright slanderous, and you should retract it.
