Nvidia 352.30 Stable Driver for Linux Has Lots of Fixes and GeForce 910M Support

Nvidia has released a new Linux driver in the stable branch and has fixed a few outstanding issues. The company also provides support for the latest GeForce 910M chipset.

Nvidia maintains a number of branches for the drivers, and it’s getting harder and harder to keep track of them. There is the short-lived branch that gets most of the action, the long-lived branch that usually lands in repositories, and the stable branch, which sits somewhere in the middle.

Vector Light Linux 7.1 Is Based on Slackware and IceWM

Vector Light Linux, a distribution based on Slackware that uses the IceWM window manager by default, has been released and is now available for download.

The Slackware-based Vector Linux has numerous flavors, and this is the update for just one of them. In fact, the release of the standard edition happened a month ago. The Light version is a little bit different from that one. It’s aimed at users with lower hardware specs, and it’s a little bit smaller than the regular vers… (read more)

New: Univention Apps – Enterprise Applications instantly ready for use!

Univention has created Univention Apps – A strong combination of one of the existing apps from the Univention App Center, the Univention App Platform, which is based on the Linux distribution Univention Corporate Server, and the UCS management system. These ready for use apps can be very easily started as virtual machines or installed locally.

Univention Apps integrate seamlessly with each other and into existing (Active Directory) environments, and come with integrated update mechanisms. The range of these Univention Apps is wide, from groupware and document management up to filesync/-sharing and backup solutions and will be extended continuously.

Univention Apps are perfect for end users who want ready-to-use business applications, on the cloud or on-premises, combined with an easy identity management and the possibility to integrate them into the existing IT environment.

Cloud service providers are also welcome to integrate the Univention App Platform into their provisioning system with the opportunity to offer their customers an individual selection or even the entire range of available Univention Apps.

If you are an app vendor, you are very invited to certify your app for the Univention App Platform and take advantage of the steadily growing network of cloud service providers that are offering Univention Apps.

The Linux kernel mapping fixed resolution

The new version of the kernel for stored in IDTR register is the kernel of IDT table of addresses to use fixed mapping of linear addresses, so here to fix the kernel mapping addressing mechanism to describe.

A New SysAdmin Pledge in Honor of SysAdmin Day

Bryan LundukeThis Friday is what I consider to be, without the slightest glimmer of doubt, the most important holiday of them all…

System Administrator Appreciation Day. “SysAdmin Day”, for short. Or simply “SAD,” for really short.

“Surely you jest!” you say. “Reginald, my good man! Come over here and observe a rather silly thing that this Lunduke chap just posted to the world wide web!”

I jest not, my old-timey-sounding friend! SysAdmin Day, celebrated on the last Friday of July, marks the one day each year that we are – obviously – legally allowed to tell our SysAdmin that he or she has done a good job.

This most glorious of holidays came into existence in the year 2,000 – making July 31st the 16th annual occurrence – when this one particularly wise man, Ted Kekatos, decided that SysAdmins should be celebrated with their own holiday. With cake. And balloons. And confetti. (Those are some of the recommendations from none other than SysAdminDay.com. Apparently all SysAdmins love confetti. Who knew?)

In case you were wondering… Ted Kekatos is a System Administrator.

But that doesn’t mean that Ted is biased! No, sir! It simply means that he, as a SysAdmin, was one of the most qualified out there to judge the importance of granting this noble profession its own holiday.

In fact, history is filled with examples of great people declaring a holiday for themselves. Take Christopher Columbus, for example. Upon discovering “The New World”, Columbus immediately declared the second Monday in October to be “Columbus Day” (to be celebrated with cake… and balloons… and confetti). It took a year or two to catch on, but before the decade was through, most of the world was already celebrating this new holiday. It’s true. Look it up.

Ok, that is absolutely not true. Don’t look it up. But it’s on the Internet now. Which means, one day in the not-too-distant future, it will become true. So long as the Internet keeps running. Which it probably will. Because we have SysAdmins.

Really, when you think about it, SysAdmins are the MOST deserving of a holiday of any profession or person. Period. On the face of the Earth.

Your computer at work. The network at your office. Your email, file and web servers. Hell, even your printers. They all work because SysAdmins fix your computers and keep the world spinning.

If you think about it, the whole freaking Internet is working – right now – because of SysAdmins.

What did Christopher Columbus ever do? Took a cruise to the Bahamas then went back to Spain and grabbed a quick dinner at this great tapas restaurant he knows of. And he got his own holiday. When you think about it like that, it makes you wonder what took us, as a species, so long to recognize the profession that keeps our email sending and our Netflix streaming with a special holiday.

I mean, just give a quick read to the oath that every SysAdmin swears:

“Neither snow nor rain nor heat nor gloom of night stays these couriers…”

Wait. That’s the mailman pledge. Why did I think of the mailman pledge? Oh! I remember, now.

“In brightest day, through Blackest Night, No other corps shall spread its light! Let those who…”

Nope. Nope. Hold on. That’s Green Lantern.

Is there no awesome pledge for SysAdmins? The closest I have been able to find is this snippet from Peter Hansteen’s seminal work, Firewalling with OpenBSD’s PF packet filter. It’s not exactly a SysAdmin Pledge, but it’s a good start.

“The Pledge of the Network Admin.
This is my network. 
It is mine 
or technically my employer's, 
it is my responsibility 
and I care for it with all my heart.
There are many other networks a lot like mine,
but none are just like it.
I solemnly swear 
that I will not mindlessly paste from HOWTOs.”

It’s good. It’s good. Just a little… long. System Administrators don’t have time to lollygag around reciting oaths like this. They need something short. Something punchy. Something that conveys their pain and their strength. Their passion and their… disdain for printers. Here’s my offering:

“At 2 am.
I am on call.
Mountain Dew powered.
I hate this printer.”

Now go, SysAdmins! Enjoy your day! Enjoy the massive quantities of confetti you are sure to receive!
