A History of Money

Wow! This is one of the best articles about the history of money I have EVER read! If you want to know a bit about what runs every country in the world, read this!

History of money

P.S. Its a bit long, so you may want to send to your kindle or something if you have one ^_^  Very much worth the read though!

LTSP Update

So I got LTSP running on about 15 LAB computers all at once, and after getting a few applications running locally instead of on the server, the computers are rockin 🙂  Unfortunately the school has to wait a bit before putting it into production, but they are good to go now!  I look forward to having the kids and teachers use them and give me some feed back. 

I am getting back into some tech training and plan to finish my TCP/IP 6 training and then moving onto some CompTIA certs like Linux+ and Server+. 

In other news, ubuntu is making their OS for phones.  Looks pretty neat, but I probably won't jump on that right away, but will try it on my Note 2 if its ported there. 

2013 & LTSP!

So, its 2013!  We made it past the horribly over ratted and misunderstood mayan end of the world (actually end of an age).   Its been a pretty good end of 2012 / begining of 2013 as far as my business goes.  I have been messing around with EdUbuntu and the LTSP (Linux terminal server project) and that's been awesome.  I'm going to introduce it to a school next week if all goes well.  Basically it lets me send out a image that loads off the server through the network to a bunch of low powered desktops.  This is good, because their computers are old, crappy and they have no budget to replace them (like a lot of schools).  Not to mention Edubuntu is free!  

Now I'm impressed with LTSP, because after a day of messing around with it, its actually really easy to manage, maintian, update and just generally mess with.  For my original messing with it, I just installed LTSP on top of Ubuntu and it didn't take long to figure it out (assuming you have experience with linux and the CLI).  The options are simple and useful, decently well documented and a breeze to get up and running.  I have just tested it on one computer + the server I had laying around, but I'll try and post an update after getting a bunch of other computers on it at the actual school.  

Happy new years every one!

Proxmox (Ver. 2.1)

So I have been playing with proxmox 2.x for a while now, and its pretty awesome compared to 1.x.  The layout and options are sweet (from the web interface).  I have since updated a client of mine from 1.9 to 2.1, and for the most part things went fairly smoothly.  Even windows server 2008 seemed to run better and not crash!  Big plus ^_^  But I did hit a snag when the backups no longer worked.  They would start but never finish past a certain point in snapshot mode, which of course was a problem … So after a few weeks of poking around, I found it was the LVM snapshot settings.  Had to adjust /etc/vzdump.conf to different size setting.  The config file was blank (so all defaults i guess), which should make the size setting 1024.  Changed to 8192 and now it works perfectly.  I'm not sure if it really matters having the setting that much higher .. but from my understandings, its just the size of space reserved for any changes made to the VM image while its being backed up.  AKA as far as I know, it stops writing to the main image, and writes all changes to a seperate "space" until the backup is complete, after which it merges.  So having it that big should only take that space away from other stuff … Since i have space to spare, should be good to go!  In reality though, this could probably be set to 4096 or 2048.  

Any way, if your looking for a Virtual Machine bare bone system, this is pretty rock solid and worth a look.  Especially if your budget is tight.  If you want to be sure things go smoothly, get the support contract with the company that maintains it.  It's always worth supporting companies that put things out for free any way!  

Xubuntu 12.04

So I have been using Xubuntu 12.04 for a few days now.  Oddly enough, I think I like the Xfce desktop more so then unity and probably gnome3 … although gnome3 isn't bad.  I also installed it to a USB stick, so I can take my desktop around with me to almost any computer.  So far so good, but I'm getting a faster USB Flash drive to help out load performance and performance in general if I'm doing too much (like lots of chormium tabs open).  Xubuntu also seems to be glitching less.  For some reason Ubuntu 12.04 kept crashing a few things, especially empathy connecting to authorize my chat logins (facebook / gtalk).  Since xubuntu uses Pidgin, no problems, although I remember reading it saves passwords in plain text… so I did encrypt my home directory.  I also encrypted it because it is on a USB stick, and I didn't want to lose it and have some one get complete access to all my files!  

I found out a few other cool things today!  Like holding down the Alt and right mouse button and dragging from inside a window will actually resize it.  So you dont have to try and perfectly put the mouse on a corner or side!  SOO much easier.  I can't tell you how annoyed I got trying to resize something on a 1080p monitor with a decently sensitive mouse.  Finding cool things like this reminds me of the more time you invest in figuring out Linux in general, the more you are rewarded.  At first glance, you may not want to ditch windows or Mac for any variant of Linux, but the more time you spending learning about it, the more your going to love it!  The 3 bigest things I love about linux are

1.  Loads of choice!  There are thousands of apps you can use, to tweak the intire OS.  I love the fact you can install multiple desktop interfaces (gnome, xfce, unity, etc) and just pick what ever one you feel like using on logon.  

2.  #1 works right into #2, which is customization.  Most of any distro is Free Open Source Software, which means you can tweak the software any way you want.  This gives even more choice with all your choices!

3.  The majority of Linux software does not cost money! Only time to figure out and learn to use to its maximum potential.  

 

Remember kids, Linux is free to download, distribute and use.  It can also be run directly off the CD to try out or a USB stick.  So start playing around with it and have some fun!  Technology is cool 😀  

 

Been awhile since a post!

Its been a while since my last post so… thought I'll just do a random post with misc. Updates. 

For starters, I am now using Ubuntu 12.04 as my primary OS for general use.  Its not bad, but it does crash randomly… not completely, in fact it seems to be mostly the google part of empathy, but also some random other stuff but not nearly as noticable (says chromium crashes, but it didn't).  I am also using Gnome 3 as my primary UI, as it seems more responsive and I like how it works more then Unity.  I also had issues with the nvidia close source driver, so I went back to the reverse engineered open source driver and it works better… in compatibility not performance.  

Hmm Proxmox has come out with 2.1 as well, which is a awesome upgrade over 1.9.  I have setup 2 of "servers" with it and clustered them (not with HA though… need extra equipment).  Its pretty awesome how its all laid out, and having the ability to "backup now" instead of trying to set a temporary backup a few min ahead is nice ^_^  

My friend matt has re-light my interest in Seti / boinc and I have setup a VM on both my Proxmox servers that run boinc now.  Should start cranking out a few more units (before it was pretty much just running on my step dads computer).  

Lastly for this post, I have got a e-reader (Kindle touch) and have been reading about liquid thorium reactors (safe nuclear energy).  Its actually really interesting and can solve a lot of the problems we have with current nuclear reactors (uranium light water reactors).  Other books I have been reading include Windows Server 2008 R2, Ubuntu desktop / server book (the "Official" ones).  

Any who, I'll try and get something "cooler" to post later.
