ISS Captures SpaceX Dragon Capsule 217

Posted by Soulskill
from the congratulations-folks dept.
Today at 9:56AM EDT (13:56 GMT) the robotic arm on the International Space Station successfully captured SpaceX's Dragon capsule. It's the first time a commercial craft has connected with the ISS, and the first time a spacecraft made in the U.S. has gone to the station since the retirement of the shuttle. The approach was delayed temporarily as engineers worked out bad sensor readings due to light reflected off the ISS's Kibo laboratory. "To work around the problem, SpaceX narrowed the field of view for the laser sensor so that it wouldn't pick up light from the offending reflector. Dragon then returned to the 30-meter checkpoint and moved in for the final approach." If all goes well today, the capsule will most likely be opened tomorrow. Video of the operation is being broadcast live on NASA TV.

I was given a p4 optiplex desktop which I am using for my fileserver. I have a pair of 1.5tb disks and a pair of 2tb disks in mirrors running freeNAS on a usb thumbdrive. The optiplex is great because is quiet, fast enough and the case conveniently fits 4 drives(and free). I have a cheap 4 sata card for the drives and I splurged on a decent intel gigabit nic after couple other cheap ones with no luck (asus and dlink I believe). If you do the thumbdrive thing, make sure and buy two and dd the contents over, one failed on me and now I have to manually manage my raid via cli. Of course this does not protect me from myself, but I haven't lost too much due to my own stupidity. I used to have a larger fileserver with all sorts of little drives, but I replaced them with a couple big ones and I'm much happier for it. Lots of people swear by drobos. One person I know plugs a decent usb drive into his hacked router. Rsnapshot is good for automatic incremental backups.

I worked 10-12 hours per day 10-18 days in a row as a skilled construction worker in the Oil Sands of Alberta Canada. My government and union invested in me to get the small amount of training required for the position. Some companies import foreign workers who will work for less, but they also make more mistakes which can be very very expensive. I lived in remote camps, I was attentive and always ready to work. I was paid $90k in my first 10months. What this article is describing is an American problem, not a western one. Train your youth in trades and technical certs. It will pay itself back with bucket fulls of income tax.

I never noticed any of this /w dedup and compress on. it chugged along and responded just fine. Manual "memory tuning" is not required, my 5tb file server w/ 48gb ram has no problem addressing memory whenever it wants /wo any tuning. ZFS is a beast, regardless of os or hardware but that is the point. You don't get bit loss protection, ram caching, compression or de-dup hash tables for free.

I wasn't very scientific with my testing but I don't think duplicates were any faster. I believe the bottleneck is the CPU (a single $500 xeon). I am mostly interested in read speeds which were more or less unaffected. Capacity, bit rot protection and ease of array management(zfs labels drives for easy importing) are also very nice features.

ZFS v28 not a highlight? I just finished testing a 5tb Freebsd 9.0rc2 Supermicro server. ZFS v28 adds de-duplication and a removes rather nasty failure when an intent log device is removed. It also had built in support for the LSI HBA controller card I used, which made installation much easier. We'll save at least %40 with compression and de-dup but it does half write speeds with our xeon 5600(200MB/s down to 80MB/s) .

I tried a cheap $5/month vps for a while, it was trouble. First they falsely claimed that I was maxing out my transfer limit and I switched to linode after a bunch of os files became corrupted. I haven't had an issue with linode and a few of my friends use them. Also 128mb a bit inconvenient for most things(watch out for orphaned ssh sessions chewing up ram at 5mb each).
