crossposting

Hacker News was down all last night. The problem was not due to the new server. In fact the cause was embarrassingly stupid.

On a comment thread, a new user had posted some replies as siblings instead of children. I posted a comment explaining how HN worked. But then I decided to just fix it for him by doing some surgery in the repl. Unfortunately I used the wrong id for one of the comments and created a loop in the comment tree; I caused an item to be its own grandchild. After which, when anyone tried to view the thread, the server would try to generate an infinitely long page. The story in question was on the frontpage, so this happened a lot.

For some reason I didn't check the comments after the surgery to see if they were in the right place. I must have been distracted by something. So I didn't notice anything was wrong till a bit later when the server seemed to be swamped.

When I tailed the logs to see what was going on, the pattern looked a lot like what happens when HN runs short of memory and starts GCing too much. Whether it was that or something else, such problems can usually be fixed by restarting HN. So that's what I did. But first, since I had been writing code that day, I pushed the latest version to the server. As long as I was going to have to restart HN, I might as well get a fresh version.

After I restarted HN, the problem was still there. So I guessed the problem must be due to something in the code I'd written that day, and tried reverting to the previous version, and restarting the server again. But the problem was still there. Then we (because by this point I'd managed to get hold of Nick Sivo, YC's hacker in residence) tried reverting to the version of HN that was on the old server, and that didn't work either. We knew that code had worked fine, so we figured the problem must be with the new server. So we tried to switch back to the old server. I don't know if Nick succeeded, because in the middle of this I gave up and went to bed.

When I woke up this morning, Rtm had HN running on the new server. The bad thread was still there, but it had been pushed off the frontpage by newer stuff. So HN as a whole wasn't dying, but there were still signs something was amiss, e.g. that /threads?id=pg didn't work, because of the comment I made on the thread with the loop in it.

Eventually Rtm noticed that the problem seemed to be related to a certain item id. When I looked at the item on disk I realized what must have happened.

So I did some more surgery in the repl, this time more carefully, and everything seems fine now.

Sorry about that.

Lmao at this Mickey Mouse bullshit

The guy wrote viaweb in like 1996 when there were 10 people on the internet, sold it, and retired to a life of talking about how great he is and throwing pennies at geeks. At what point would you expect pg to learn about being careful with production servers? This is a man who thinks that running a repl inside a live server process is a good thing

I actually run production REPLs (or their equivalent) from time to time and it can be pretty useful to diagnose poo poo or restart subsystems.

I'm now tempted to find out how many levels of Iterators of Iterators you can recursively iterate, but I feel that looking any deeper at this framework will be like looking into the abyss

quote:

You can create your macros and all your extra ad-hoc library under the application/library folder.
I for instance keep a macros/ folder under library (application/library/macros) and there I save my macros.php file which is not a class.
Since it's not a class you can't autoload it using spl_autoload_register or by adding it to the Autoloader::map(array()); array in your start.php file so you can include your extra library files programmatically by implementing something like this in your start.php file:

In application/start.php I put this:
PHP code:
$path = path('app') . '/library';

$libObjects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
foreach($libObjects as $file) {
    if ( $file->isFile() )
    {
        require ($file);
    }
}
This way you wont need to include each file manually. Which comes in handy if your library grows steadily as you application grows.

Test it out in a simple test application to get you going. Like f.ex. making a folder containing an index.php file, a lib/ folder and some files unders there, and perhaps yet another folder under lib/ and more files under tat folder. Put this code into your index.php file and try echoing out the filenames by instead of doing require ($file) like in the code example above, you do echo $file, '<br>';

Enjoy.

netbsd is the clean and proper bsd in that it is trapped in 1995, yes. mandatory access control? who needs it

freebsd is unclean and un-bsd because they make a (half-assed, under-funded) attempt to be modern

openbsd was founded by people who were not as business-focused or tolerant of change as netbsd core dev team. they fantasize about perfectly secure code because it passes valgrind. in other words it is netbsd minus years of effort

nobody's code is so perfect that it doesn't need mandatory access control. MAC is hard to implement, and unsexy, so they magically don't need it. never mind that every "trusted" unix for govt use and linux and freebsd and nsa poo poo all have it

thanks mr. bsd all i know is that they complained that other people wrote unportable code relying on custom wacko nonsense interfaces saying that we should instead port to their custom wacko nonsense interfaces.

legends tell of openbsd breaking because of a #ifdef NETBSD. don't forget openbsd started because theo didn't play nicely with others.

openbsd sucks because they're too big to admit that they've shipped bugs, and blame their users for having an os that does more than boot.

my experience of python has been that it has been quite boring for most of the time i've been following the gossip and development. there is python-ideas but you'd have to be a total idiot to go there.

python has a grounding in things outside making web applications, and is used for a couple of things like distributed processing, bioinformatics and numerical simulation, and even cas systems. it has a grounding in academia, with a bunch of stuff trying to do science in it. perl similarly has a grounding in the unix shell, but python has been slowly eating away at the monopoly it once had for gluing larger poo poo together.

now they're old and boring, the communities are older and considerably more dull. i do remember when perl 5 had a lot of zealotry when it was still fashionable, and python was 'disruptive' at one point too.

on the other hand, some languages are less fortunate and suffer more from celebrities and fashion.

hi ruby!
