Sybase is unhappy right now so I’m removing some stats pages to try and
diagnose.

:: 20-Jun-2002 00:23 GMT (Thursday) ::

The last several rc5 stats-runs have died due to a deadlock on the email
ranking table. To work around this problem, I’ve changed several stats pages
so that they will read uncommitted data. This will result in the possibility
of some odd numbers being displayed during the stats runs. So if you see odd
behavior, just wait a few minutes and refresh, it will probably go away.

On a related note, stats are slowly getting caught up. The rc5 run for the 17th
is almost done, and we should be caught up completely in two days.

RC5 hit a deadlock on the 14th, so that’s why nothing has happened since then.
I’m doing a manual run now, so stats might be up and down a bit.

As a lot of you have noticed stats are currently behind.
Decibel who was looking at stats and posted a plan update on 13 june,
is away and is due back tomorrow.

Stats are unlikely to be run until decibel gets back and has had time to
look at them.

The stats pages are now running the new codebase, and although there are
still some issues to be resolved, seem to be running smoothly.

We had to remove one SQL query from the php pages which was causing sybase
problems, and are looking at the best way to fix this.

If anyone has any further issues or problems with the stats code, then you
can send an email to paul@distributed.net

Looks like I need to do a manual run, so I’ll be turning stats off for awhile.
Should be back in an hour or so.

Sorry about the lack of stats, problem solved and stats are running right now.

*wiping egg off face*

Ok, I now see what some people were talking about with the stats for April 7-9.
They definitely look foobar, most likely a problem from when we started the new
statsruns up.

I’ll work on correcting this problem.

:: 10-Jun-2002 18:45 GMT (Monday) ::

For those who have noticed differences in the numbers, this is most likely
due to bugs that were present in the old stats code. We run an audit script
at the end of every daily run of the new system that does a sanity check on
the numbers represented by all the different parts of the system. It would be
difficult to overstate it’s value; at least a dozen bugs have been identified
thanks to this script as the new stats code evolved from it’s inception.

Because of this audit script, I have a very high degree of confidence in the
new stats code. We migrated the rc5 data from the old system into the new
system several months ago. Part of that migration was modifying the raw data as
best we could so that everything would actually pass the audit script. Since
that time, rc5 logs have been processed by the new system each night, as well
as the old system. This period of both systems running is what has allowed
people to do most of the before/after comparisons I’ve seen.

What this boils down to is that any rc5 stats processed by the new system
(ie: anything in the past month or two) can be assumed to be 100% correct and
accurate as compared to the logs provided by the master. Anything prior to that
time could still be off.

At some time in the future, I would like to start re-processing all of the rc5
logs from the beginning of the project. This should correct any other errors
that might exist in the rc5 stats.

For Sony PlayStation 2 users:

Yes, Linux[mips/PS2] is the first client for PlayStation 2!
http://www.distributed.net/download/prerelease.html

The RC5 core is mips-crunch.cpp.
Special thanks to Michael Mallory,
-pedantic solution was discovered by him.
I didn’t change mips-crunch.cpp
because it might make an influence to other platform.

It’s *REQUIRED* “Linux for PlayStation 2” kit.
There is no method which runs it without this kit.
You may think it’s able to boot from PS2 Memory Card, but it’s impossible.
PS2 Linux (or any unix variants for PS2) is booted
only from the Runtime Environment in Disk1.
Therefore, if you don’t have this kit, please purchase it!

(for Japanese: We can’t buy it now.
See http://www.jp.playstation.com/linux/ )

If you have PS2Linux, you can run it without HDD(or BB) unit.
http://achurch.org/ps2/ (written by Japanese language)
Install ps2linux-boot-ntsc.tar.gz and dnetc to /mnt/MC00.

Once you do it,
you may install the “Final Fantasy XI online” to HDD :-)
Both “Linux for PlayStation 2” and “PlayStation2 BB Unit” are
kiting the same HDD and Ethernet unit.

Please feel free comments to me (language available: English and Japanese)

Enjoy!

There was a master outage yesterday that resulted in uncompressed logs. Until
this is fixed by one of the master operators, stats won’t be updating.
