I have been very interested in VOIP stuff for the last while now, and finally started looking at implementing it in the house. Here are some links which may be useful. I will do a full post soon.
The main VOIP hardware I use is:
I also use the 3CX software on both my iPhone and Android.
A couple months back, I got my hands on a Raspberry Pi, a tiny development board that can run a full copy of Linux, has a HDMI port, a couple USB ports, Ethernet and a few other little bits and pieces. The full specs, from the Wikipedia Article are as follows:
- Operating system: Linux (Debian GNU/Linux, Fedora, and Arch Linux ARM)
- Power: 2.5 W (model A), 3.5 W (model B)
- CPU: ARM1176JZF-S (armv6k) 700 MHz
- Storage capacity: SD card slot (SD or SDHC card)
- Memory: 256 MByte
- Graphics: Broadcom VideoCore IV
There have been a few things i have wanted to play with it for, but have not implemented all them yet… still learning… but some interesting projects have come to my attention… here they are, in no particular order:
- Raspberry Pi embedded into a Canon 5D MKII Battery Grip: The idea of this is epic! the possibilities are endless… GPS, Wifi, FTP, Processing RAW images (ok, maybe not with a 700Mhz processor…), auto upload to the internet, auto add watermark, resize images before upload, send to iPad… I could go on and on…. 🙂
- Embedding a Raspberry Pi into a Keyboard: this is pretty cool too…
- Quick setup of a Web Server on the Raspberry PI: Install Apache, SSH, PHP, MySQL and an FTP server, all on your Pi!
In all fairness, the Pi makes a lot of ideas possible. with such a small size, and such a cheap price ($25-35), you are only limited by your imagination… Wonder could i get Windows 8 installed on one of these…
there are also a few interesting things that may make the Pi work more portable…
- LiPo Rider Pro: takes input from Batteries and Solar Panels and outputs as USB 5V. should run the Pi off solar and batteries for a while… 🙂
This site is built with GIT, GitoLite and Jekyll… I posted about this before. but how do you setup your own Git Server? checkout How to install and Setup a Git Repository Server using Gitolite on Linux Ubuntu 10.04 and 11.04 on mmncs.com. I am using Ubuntu 12.04, but its mostly the same…
So, Windows Server 2012 and Windows 8 have both RTMed in the last couple of weeks and will be available to the public in the next month or so (September for Server, October for Client). If you are an MSDN Subscriber, you already have Client, and will (hopefully) get server in the next couple of weeks… Fingers crossed… Anyway, one of the interesting features i am waiting for is [Storage Spaces]. Tim Anderson’s Gadget Writing blog has some information on [how Storage Spaces works]. handy notes on what to do and what not to do.
My new Favorite cross platform text editor is Sublime Text 2. It works on Windows, Mac OS and Linux, and i am very happy with it. My only problem is the path to start it is not exactly easy to type… So, with the help of PowerShell, my new favorite command line tool on Windows, i added an alias:
Set-Alias subl 'c:\program files\sublime text 2\sublime_text.exe'
I added this to my Microsoft.PowerShell_profile.ps1 file in Documents\WindowsPowerShell folder. If you don’t have one of these files, check out this Computer Performance.Co.UK post on Creating PowerShell profile files and then edit the file and add the line above… Now, I can edit files in PowerShell with Sublime Text 2 by typing:
I have a few Amazon EC2 instances running on a project, and one of these instances was known as the Zombie Instance! Every time i killed it, it came back to life a few min later… I found out that i, at some point, set that instance to be in an AutoScaling group. Any time the instance died, Amazon would check and restart the instance. So, how did I kill this undead instance? Check out “Auto Scaling with Amazon EC2 II” on LLOVIZNA’s blog. They had the same issue i had (trying to kill the Auto Scaling group gives an error) and figured out how to do it. Handy stuff. Now the instance is dead, and hopefully it wont come back any time soon… Mind you, When AutoScaling works correctly, it can be very cool indeed!
So, this site is brought to you by GIT, Jekyll and Magic… here is how i did it…
- I have a Linux VM running the site. Its an Ubuntu 12.04 server. On that i installed Jekyll.
- I also have gitolite installed for personal git repos.
- In the Git Repo for this site, under the hooks directory, I added a post-receive file which I got from here originally.
- Apache is set to serve the directory that Jekyll produces… That’s what you are reading here.
- If you are interested, you can find the code and config for this site on my github repo
