Why the cloud is killing Windows

I’ve been watching an interesting development in the business IT world, our customers gradually moving to Linux OS desktops for workstations. This is happening on the server level as well.

The benefits/downside of a Linux desktop are fairly straight forward. Linux is free, doesn’t get viruses (yet…some argue once market share is high enough viruses will come) and takes much less horsepower to run.  On the downside, it won’t run most Windows based programs. There are myriad other pros and cons to go on the lists, but these are the main things customers notice and care about.

So what does this have to do with the cloud and Windows?  It’s pretty simple really, most of our customers are moving to a Linux desktop OS because the cloud allows them to do so. Their applications and data are going to the cloud, which runs almost exclusively on browsers. Browsers run GREAT in Linux. So once your local Quickbooks, email and other Windows only programs have been replaced by cloud based services you really don’t have much tying you to a Windows desktop anymore. And thus no more viruses, paid upgrades and slow performance from a bulky OS.

The second and less common reason is virtualization. Many customers are seeing the light of terminal services or remote desktop solutions. Your local desktop machine is connecting to a terminal server or virtual desktop service and all of your data is being delivered from there. What local OS you run is a non-issue since you now use a browser or terminal services client to connect, which once again run GREAT in Linux.

All that being said, from a business perspective at least…Windows is waining in relevance for many of our customers since they no longer are running their applications on their local machines.

Open Office – spell checker not working

Using Open Office has saved our company thousands in licensing fees. Everyone in our organization uses it and we have yet to run into a compatibility issue when sending files to our clients. Sometimes we’ve found that the spell check doesn’t install properly initially and it is necessary to manually set it up. You’ll need to install the dictionaries and ensure spell check is enabled.

Here’s what we did to get it going. Note: You will need to be connected to the Internet so the dictionaries can download.

1. Go to File -> Wizards -> Select your language -> Click the “Start dicOOo” button.
2. Now follow the prompts until it asks you to restart Open Office
3. Once restarted go to Tools -> Options -> Language Settings
4. Under Writing Aids verify/modify the settings and click OK.
5. Under Languages verify/modify the settings and click ok.

You should be good to go. I had to modify mine in one more spot because my Locale is different (long story).

1. Under Format -> Character -> Font the “Language” setting should match what you set in your Language Settings -> Languages

Now any new document you start will have spell check enabled.

We referenced this forum post, spell checker in openoffice.org, to get us started on the right path.

Download a copy and give it a try! OpenOffice.org

Hope this helps! :)

Asus M3n78 Pro with Ubuntu Hardy 8.04

Another board that works reasonably well for Ubuntu Hardy is the Asus M3n78 Pro. This board costs quite a bit more money, but it is a full ATX sized motherboard instead of the Micro ATX boards I discussed in a couple of previous posts. Some of the more notable features of this board are the four Memory slots, 3 PCI Slots, 2 PCIe 1x slots, a 16x slot and an integrated Gigabit NIC. This would not be a bad board for a MythTV backend server that you wanted to stick a bunch of disks and recording devices in. In fact, this is the exact board that I rebuilt my home server onto. Everything worked out of the box with this board except for the video which required that I install a newer video driver. The server now runs headless anyway now though.

Asus M2N68-AM SE2

For the guys that have been building systems with the Asus M2N68-VM, you will notice that inventory has been drying up. Even newegg.com does not have them sale anymore. One possible replacement for a low end workstation is the Asus M2N68-AM SE2. It has a similar, but scaled back feature set. They drop HDMI connector, drop from two to one PCI slot, drop the gigabit nic to a 100 Mbit nic and also drop down to two SATA ports from four. The video is a similar 7000 series chip that is compatible out of the box and it does have the same Nvidia nForce 630 Southbridge that just works with Ubuntu Hardy, 8.04. This is the Linux version that we prefer to roll for our Spokane based customers that need computers that just work for their standard web applications and word processing chores. This is another one of those board where everything just works out of the box.

Connecting to your remote cam with mplayer

We install a lot of outdoor cams for various reasons. Security cameras for construction sites, Several ski resort outdoor camera solutions, and in store security camera systems to name a few.  One of the fun things we’ve done here was a job to play a multi-media loop in a ski lodge. The resort wanted pictures, videos, and live shots from the camera on the hill.

We found an easy solution to playing the live video in mplayer. We used an Ubuntu 8.10 Hardy install on a laptop to drive the presentation that was programmed in python.

mplayer -fps 25 -demuxer lavf -user <cam username> -passwd <cam password> http://<cam ip or dns name>/axis-cgi/mjpg/video.cgi?0.mjpg

This will connect to web based video cams; axis and stardot netcams have been tested.

If you have any questions regarding outdoor cameras for your business or location please call us at 509-465-1234 or visit our main site at http://www.interlinkadvantage.com/all_weather_security_cameras.php

Motherboard for Ubuntu 8.04 Hardy Heron

We recently set out to find hardware that is compatible, out of the box, with Ubuntu’s latest Long Term Support (LTS) release 8.04 also known as Hardy Heron. This proves to be a bit more challenging than you might think since many of the motherboards sold today hit the market after Hardy, as geeks like to call it, was released. Most motherboard and their respective component manufacturers are on a fairly rapid release schedule these days. So the challenge is to find a motherboard built from components that are at least a couple of months older than the release of the the Linux operating system you wish to run.

One of the standouts that we found was the Asus M2N68-VM socket AM2+ based motherboard. It has integrated an nVidia 7050 video chip with analog VGA and digital DVI based connectors. The video chip is supported out of the box on Hardy both with the open source nv driver and nVidia’s proprietary but functional nvidia driver. Nvidia supports X-Video Motion Compensation (XvMC) on hardware up through the 7000 series so this chip should be supported with possible MPEG 2 assisted decoding. This has not been tested yet though. Coupled with the built in HDMI connector it seems like it would be part of an ideal solution for a low cost MythTV / Mythbuntu machine especially when coupled with one of AMD’s low wattage processors.

The board uses an nVidia 630a chipset which seems to be well supported so other boards based on this chipset may be supported as well.

Every component that has been tested including Cool N Quiet and CPU frequency scaling work out of the box. If you have any questions feel free to ask them in the comments section.
