xbox 360 – first impressions

technology

of course I am not a gamer. Let’s put it that way: the last time I looked a t fps (-> that also could mean “First Person Shooter” I have learned) was when it was called doom. I think doom runs on cellphones and/or iPods these days.
So, back to the Xbox 360: It really looks, well, not that great. The power supply is a big black brick. The thing itself is oddly shapped.
It has surprisingly few connections: A 7(?) ended whiplash for the video. USB and ethernet. And some memory thingy in the front.
HD is nice. 1080i and 720p look alright. Only looked at so-so Panasonic Plasma. That top of the line stuff from two years ago.
The aliasing was the biggest dissapointment. Some Racing game and it was PS1 all over again. But maybe I just have not see enough games. Never really get used to it. I am surprised though.
Modeling and texturing was so nicely done in this particular games. Just a shame that the anti aliasing was making every sizzle.
Glad I am not a gamer. Didn’t look like fun to me …

Matt Drudge has a huge audience. Somebody somewhere misrouted a video signal or was unable to operate a switcher correctly.
People found quickly that there is not only an “X” over the image but also a message saying “Transition begins after 5 frames of black”.
Which is why the text below his face is not that readible.
Still, the white is concerned (according to Drudge and some ‘source’).
Maybe this was an ‘counter image’ attempt. After all George
not being able to walk away from a press conference was a very
telling one.

one click infection

Apple

I really really hope that Apple keeps it’s OS clean. Again: There are no viruses or other scamware for OS X.
And I like that, since I can focus on other things. How can people still use Windows and keep up with this kind of ongoing junk?

sar under OS X 10.4.3

Apple

what a weird hack! OS X comes with the sar command, which I found to be very helpful to look at what a machine is doing.
Just running
sar

Will look for todays performance. You have to collect it first. Traditionally this gets done via a cron job. OS X really likes to use launchd instead. But I need to get some work done, I don’t have the time to learn another propriatary solution for a very common problem: Running things periodically. So I stick with cron. Not sure why it is running on some of the systems and not on others. If you follow this make sure cron shows up in a ps ax | grep cron command. If it does then you could enable daily performance traces reportable by “sar” by adding

# run system activity accounting tool every 10 minutes
*/10 * * * * root /usr/lib/sa/sa1 1 1
# generate a daily summary of process accounting at 23:53
53 23 * * * root /usr/lib/sa/sa2 -A

to /etc/crontab. If cron runs then it will reread the file automatically. The remaining problem for me and under
OS X 10.4.3 was that sa1 overwrote instead of appended the performance data. A really terrible hack that fixed this was to change the lines in /usr/lib/sa/sa1 from

exec ${ENDIR}/sadc 1 1 ${DFILE}

to

exec ${ENDIR}/sadc 1 1 >>${DFILE}

This works, but generates error messages like:

sar: drivepath sync code error -4

when I retrieve the daily performance data.

This is good enough for me. All I am after is to find out what that 30TB Xsan has been doing.

simple and nice

surprisingly simple yet nice.

xsan admin don’t bother with the GUI

Apple

in case you should consider to get an xsan I would recommend not to bother with the ‘Gui’ for the Xsan Admin utility.
While you still can break the thing make yourself familiar with ‘cvadmin’ in the terminal.
Once the thing is in use that so called ‘Gui’ will be just getting in the way. Much like the early OS X Server UI it is a bad hack that does not conform to the Apple UI guidelines. It will not give you any feedback if there will be an update or not on what you see. Managing terrabytes through a wacky interface is not even not fun, it is terrifying …

cvadmin is your friend. As much as Xsan can be your friend that is …

this is what is going on.

Nice to know in general. But especially if things get weird.
