SuperMicro X9SCL/X9SCM hard disk update image

May 15th, 2012

With Intel’s release of the Xeon E3 1200v2 CPUs yesterday I have had to come up with a creative solution to update the BIOS on hundreds of SuperMicro X9SCL/X9SCM motherboards to support the new CPUs.

I feel that laziness is a virtue in System Administration so I created a image file that can PXE boot into DOS and handles the update automatically.

The file is here:

X9SCL BIOS Updater

I’ll assume that you already have a Linux based PXE setup; this is the command I use to call it with pxelinux:

label X9SCL
KERNEL other/memdisk
APPEND initrd=tools/c.img harddisk

Enjoy!

 


The best WordPress performance tip, ever.

June 12th, 2011

If you’ve ever used WordPress to host a blog than you know that it is a very powerful platform. With a lot of power comes a lot of complexity. This complexity combined with the mandate that WordPress be easy to use/install/run combines to make for some interesting choices as it pertains to performance.

Recently I was tasked with building a high performance WordPress system for a user. I won’t bore you with all of the details but I will give you 1 tip that saved the day for me.

Vista Anti-Virus 2011– Seriously, Microsoft?

March 21st, 2011

Last night I was doing some Google queries to research a technical issue I was having with GlusterFS. I clicked on a link Google had suggested for me and suddenly the performance of my system had slowed to a crawl. I assumed that the site had JavaScript, or some other poorly implemented client-side code on it but it was really much worse.

I had been hit by malware…

If you get less spam today, thank Microsoft

March 18th, 2011

Microsoft is usually the punch line of jokes related to the security of their software but apparently they take spam, botnets, and malicious code creators very, very seriously.

In an apparent raid coordinated between Microsoft and federal authorities yesterday (as the wall street journal first reported) one of the largest botnets in the world (known as “Rustock”) was shutdown. “Rustock” was believed to be in control of over one million infected PCs worldwide and responsible for more than a billion spam messages a day.

So if you notice that the spam in your inbox is a little lighter today than it was yesterday, You might just have Microsoft to thank.

Massive earthquake in Japan leaves only the Internet as a communication method

March 11th, 2011

Cellular phone networks and land lines were disrupted as a result of the devastating earthquake in Japan leaving the Internet as the only  means of communication for most residents. This event – as well as all of the recent turmoil in Africa and the middle east just gives more power to the idea that the Internet has become much more than a medium for entertainment and time wasting.

The Internet is oxygen for people going through crisis.

The next open relay: VoIP

September 15th, 2009

In the mid to late 90s, the worst thing your organization could do is to have an open SMTP relay on your network. Spammers would use your mail server to send their spam which would lower the reputation of your server and get you black-listed. The next ‘open relay’ is likely to be insecure VoIP servers and unlike SMTP, VoIP is likely to cost you real money.

About that Zune HD thing

September 15th, 2009

I am a huge Microsoft fan, the Xbox 360 is my favorite console, Windows is my favorite OS, and the Zune has been my music player ever since it was first released (The Dell DJ was my music player before that). On the day a new model of the Zune is released it is somewhat of a tradition that I run out to Best Buy and pick one up. There are currently four Zunes in my household.

In the past the Zune has not been without its problems, it seems to take the development team a incredibly long time to fix issues with the software, it is very easy to lose all of the music you have purchased in the marketplace, the accessories feel very cheaply made, and there is no support for the device in cars or home theater audio systems. Another sore spot for the Zune has been its marketing, in the past there was no way of knowing what the commercial was trying to sell you until the Zune logo popped up at the end as opposed to Apple marketing where the entire commercial centers around the devices.

Although almost any device these days is a ‘music player’ I am more excited about the ZuneHD than I have been about any other Zune device. Built on the Tegra (NVIDIA) platform which offers a great amount of power and including a new OLED screen, a web browser, the Zune 4 software, the application store, and the inclusion of HD radio; this is most likely the largest step the Zune has taken in its progression thus far.

I will be picking up a ZuneHD as soon as the local Best Buy opens up, but if the issues continue this is likely to be the last time Microsoft wins my business. I might have to hold my nose and buy an Apple product, after all.
