Odin

Filed under: miscellaneous programming/hvf — JeffPC @ 21:01

I finally decided that enough was enough, and I ordered the parts for my new server. This means that in the next week or two, I will be replacing the good ol' dual Athlon (see below for specs), with a shiny new quad-core Xeon.

Current setup - baal:

2x AMD Athlon MP 1800+ (1.533 GHz, 256 KB cache)
2x 40GB IDE disk
4x 512 MB
1x e1000 Intel NIC

New setup - odin:

1x Intel Xeon W3520 Bloomfield 2.66GHz 4 x 256KB L2 Cache 8MB L3 Cache LGA 1366 130W Quad-Core Server Processor
6x Kingston 2GB 240-Pin DDR3 SDRAM ECC Unbuffered DDR3 1333 Server Memory Model KVR1333D3E9S/2G
6x Seagate Barracuda 7200.11 ST31500341AS 1.5TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive
1x SUPERMICRO CSE-743T-645B Black 4U Pedestal Chassis w/ 645W Power Supply 2 External 5.25" Drive Bays
1x SUPERMICRO MBD-X8STE-O LGA 1366 Intel X58 ATX Intel Core i7 Intel Motherboard

I've "stolen" some images of the case from NewEgg:

Baal gives me about 40 GB of disk space (I use RAID 1 across the two drives). Odin will give me about 6TB (RAID 6). This will finally allow me to do a few things I wanted to do for a while; one such thing is to provide a Hercules image with Linux set up to do HVF development.

STS-128

Filed under: miscellaneous — JeffPC @ 02:19

The other night, just before midnight, STS-128 launched. I took a few screenshots of NASA TV. NASA described the launch as:

Liftoff from Launch Pad 39A was on time at 11:59 p.m. EDT. The first launch attempt on Aug. 24 was postponed due to unfavorable weather conditions. The second attempt on Aug. 25 also was postponed due to an issue with a valve in space shuttle Discovery's main propulsion system.

The STS-128 mission is the 30th International Space Station assembly flight and the 128th space shuttle flight. The 13-day mission will deliver more than 7 tons of supplies, science racks and equipment, as well as additional environmental hardware to sustain six crew members on the International Space Station. The equipment includes a freezer to store research samples, a new sleeping compartment and the COLBERT treadmill.

Here's the "beenie cap" with the moon in the background:

A nice shot of the whole shuttle:

The engines:

Later on, I found this image on NASA's site. Wow.

Viewed from the Banana River Viewing Site at NASA's Kennedy Space Center in Florida, space shuttle Discovery arcs through a cloud-brushed sky, lighted by the trail of fire after launch on the STS-128 mission.

I was just watching the STS-127 launch. I couldn't help but take a couple of screenshots of NASA TV...

Right after solid rocket booster separation:

And, it looks like NASA has a nice photo of the launch:

Old Email Address

Filed under: miscellaneous — JeffPC @ 23:35

I'm going to lose an email address I had for a long while: jeffpc@optonline.net. It's because of an ISP switch. I haven't used it as my primary email address for a long while, but either way, you'll want to update my contact info to jeffpc@josefsipek.net.

RHEL 5.4: Now shipping XFS

Filed under: miscellaneous open-source — JeffPC @ 18:04

Wow, it's about time!

Sources tell me that RHEL 5.4 comes with XFS support. This is good news for all those folks wanting to use filesystems larger than 16TB and not trusting ext4 with their data (I couldn't blame them). As far as I know, these unfortunate souls have been told to use GFS2 if they wanted a RH supported fs that did more than 16TB. (It's worth mentioning that ext3 had a 8TB limit until about two years ago, when it got fixed up to support whopping 16TB.)

Blowfish on 24

I can't belive this...These TV show writers really have to be trying to get things wrong.

Designing an Authentication System: a Dialogue in Four Scenes

Filed under: miscellaneous — JeffPC @ 00:51

I just learned about a rather non-technical description of the Kerberos authentication service: Designing an Authentication System: a Dialogue in Four Scenes. It makes me feel like I should set up Kerberos on my boxes...not sure if it's even worth it, considering that I deal with no more than 3 computers (laptop, desktop, server).

Goldman Sachs

Filed under: miscellaneous — JeffPC @ 21:58

I just came across an article that points out how Goldman Sachs managed to show a fair amount of profit for the first quarter:

Goldman Sachs reported a profit of $1.8 billion in the first quarter, and plans to sell $5 billion in stock and get out of the government’s clutches, if it can.

How did it do that? One way was to hide a lot of losses in not-so-plain sight.

Goldman’s 2008 fiscal year ended Nov. 30. This year the company is switching to a calendar year. The leaves December as an orphan month, one that will be largely ignored. In Goldman’s earnings statement, and in most of the news reports, the quarter ended March 31 is compared to the quarter last year that ended in February.

The orphan month featured — surprise — lots of write-offs. The pretax loss was $1.3 billion, and the after-tax loss was $780 million.

Would the firm have had a profit if it had stuck to its old calendar, and had to include December and exclude March?

Clever, eh?

Snow

Filed under: miscellaneous — JeffPC @ 21:19

Do you know what's better than snow? Snow in April. Yep, that's right, there was a reasonable amount of snowfall overnight. I just wish I had time to go around, and photograph things.
