Corrupted Databases Are Fun 60

Posted by CmdrTaco from the ok-not-really dept.
Notice how all these stories are disappearing? Is it because I'm a censorship oriented Nazi? According to my inbox, thats the only rational explanation. The truth is that we've been having database problems for several days. Stories are randomly disappearing. Its making me really cranky. I haven't been eating or sleeping much. But I'm working on it. I'm really sorry about all this crap. Believe me, its pissing me off more than you.

    yep, that sounds like Rob. Notice that slashdot has *NO* Pro-Microsoft stories in archives. Although I distinctly remember seeing them posted and then disappearing. Damn this news site -- I want freedom of speech!!!

  • Slashdot servers are compromised? (Score:1)

    by Anonymous Coward

    Considering your database corruption and the root compromise of the Slashdot server last year, isn't it a strange coincidence that the story about the vulnerabilities in the WuFTPd and ProFTPd software should be the one to disappear?

    Rob et al, have you checked your servers in detail to see if they have been compromised again and re-installed from scratch?

    The semi-live threaded replies make this very difficult to do without a database on the backend. It can be done with a script that actually modifies the HTML each time a comment is posted but it would have to watch very very carefully so nothing else runs at the same time and it would take a while to update all the pages. Another way would be to have a master-index type of program which would generate each and every page from a set of text files but that would be ungodly slow.

  • MySQL is hardly Open Source(tm), I didn't know there was any pretense that is was...

  • I noticed a couple of comments disappear, too. And yea, they really vanished, not downgraded.
    Weird things are happening lately indeed.
    I wonder what tcx (the mysql guys) has to say about that, did you buy support?

    Apologies if my e-mail sounded critical, yesterday. I honestly thought it -was- DB corruption and I do hope that that was conveyed.

    I, for one, -don't- think you're any kind of censorship nazi and a pox on anybody who does think that. You do extremely valuable work, put in an enormous amount of time & effort, and I certainly appreciate the results!

  • we appreciate it.
  • And besides, what kind of cracker has the patience to wait months to exploit?

    A good one.

  • I'd click on a message, and it wouldn't show the body of the messages...just links to the people who've replied to it.

    Anyways, thanks for fixing.

  • Nope, I saw this one ok. It only happens sometimes. Other times, it's just a grey screen (but everything has loaded up). I just resize the screen to force things to regenerate and the page then appears fine.

  • You're doing a great job for people who appreciate it.

    Maybe we should organize a stroke-a-thon -- have slashdotters clap if they like Rob...
  • while the internet community of hackers fixes the database problem.

  • What a great group of people that Slashdot attracts. I would look at "Rob's problem" if the _current_ source was available. I bet that many others with more time than I have would also be happy to pitch in and help.

  • periodically creating static HTML files from a dynamic database.

    A fully-dynamic system has to read the DB and spew crap out for every user (could be many requests per second!) The theory is that this system is the most "live" (i.e. changes are visible to everyone immediately). The reality is that the hardware requirements of this system are very high for a moderate to high traffic site (Slashdot surely qualifies).

    A periodically updated system has to read the DB and spew data (this time to files, not users) only once every 30 seconds, 1 minute, 5 minutes, or whatever seems like a reasonable interval. Compared to running many times per second, this starts to look pretty nice. And you'd be surprised how large you can make the intervals while still maintaining a good user experience. An interval of 2 minutes would be almost indistinguishable from a truly live, dynamic system to most users, and 5 minutes is still completly within the realm of acceptability. The final optimization is to update the bare minimum files that need to be updated on each cycle. That's the real trick, but done right, it can be very efficient (thus allowing you to decrease the update interval even more). Think about it :-)

    Oh, and as for corrupted DBs, what DB server are you using?

  • isamchk [mysql.com]

    Read all about it...

  • I think the original query wasn't questioning the use of efficient access procedures so much as use of an RDBMS, because of all the other baggage that comes with the territory.

    Whether it is a good idea or not depends on whether the disadvantages of complexity and lack of transparency outweigh the advantages of clean access API and high flexibility. The answer does not always favour RDBMSs because high flexibility can be irrelevant in many cases, especially in an informal web environment. A combination of DBM files and directory-based structuring can often provide both rapid access and a lot of flexibility while keeping complexity very low and transparency very high. Furthermore, this can interface trivially with standard file distribution mechanisms to scale the whole thing up to thousands of servers if you feel the urge, and without introducing single points of failure that are almost inevitable with commit-based solutions.

    It is a mistake to head blindly down the RDBMS route without seriously considering that there are strings attached. Use them where it is *necessary*, not where the tempting illusion of a simple SQL API makes it appear merely convenient.

    Great service you have here,for the people!

  • if the source for v0.3beta were actually out there then this coveted 'bazaar' model might actually be helping slashdot's woes. same for adfu, it doesn't crash as much as it used to, but, everysooften, i do not see an ad, and instead see a 404 error overwritting the slashdot header.

    again, where's the code? where's the remote cvs?

  • I don't post much, but I just thought I'd say I appreciate your hard work, Rob. This is the only site I hit on a (many-times-during) daily basis. Thank-you for Slashdot. We'll be patient.
  • I think /. already does this. the db keeps the articles and everything, and a daemon rewrites the pages every few minutes. that's why comments dont appear immediately.

  • Everyone seems to forget that Slashdot has been growing by leaps and bounds lately. Don't be suprised that there are a few problems. Be suprised that it hasn't crashed and burned long ago.

    Why? I'd guess that it probably has something to do with the fact that Rob et al have been busting their butts to keep it running so all the Slashdot Longhairs can make them feel appreciated by telling them how much Slashdot sucks.

    I know I'm kicking a dead horse, but it seems that most forget that this is a free site, run by volunteers who care deeply about it. I'm not saying constructive criticism is bad, but there's a reason they call it constructive.

    Rob, thanks for running the best site on the Web. Keep up the awesome work. (And don't OD on those caffienated penguins!)

  • Have a cron job do a mysqldump of the database every hour - that way you at least won't lose as many articles. You could write a quick program to integrate in any newer comments using the unique IDs.

    I hope you've paid the $ 200 for support and asked the mySQL folks about this. I run a much lower volume web site with mySQL, and I've never had any problems. But in case my sites become higher volume, I'd sleep a lot better at night if I saw a resolution of some sort to these problems.

  • Jeezus, calm down buddy. Rebooting is not a solution. There is still a problem, it might just be hidden away for a while longer, or it might not come back up at all. Give CT a break, he's working at it, I'm confident that he will fix it, just give him some time.
  • I'd just like to say that I'm behind the entire /. group and that I don't think you should switcht the database unless you want to. Take your time, find out what the problem is, and fix it. If it takes 2 weeks, fine. If it takes 2 years, fine. I would like to start a fund to donate Jolt and Pizza to feed our nice /. hackers so they can get the job done and get it done right. Everyone knows that real computer nerds do their best work while loaded up on caffine. In short, if you feel like yelling because /. is broken, STFU. You didn't do anything to deserve this site and you certainly have no right to demand anything. I'd like to say thank you to /. and that I'm praying to Linus for you all.

  • Rob,

    You are indeed doing a great job with Slashdot, but it definitely seems like it's time change the database. You shouldn't use a product just because it's Open Source.. if it doesn't work, dump it. We all criticize Microsoft and other companies for writing buggy software that breaks. We should be just as demanding of the Open Source projects.

    Good luck with everything...
