cool stuff

The book I read to research this post was Linux All In One For Dummies 4th Edition by Emmet Dulaney which is an excellent book which I bought from kindle. Most people who use linux download it from the web but some pay a small fee for a disc from a linux vendor. A distro which is short for distributed operating system will often a load of extra software as well & is often on several cd-roms or a dvd-rom. There’s even versions of linux that will work with a playstation 3. One tip I’d give is get some linux magazines because they often include a dvd-rom full of linux software & it saves the hassle of downloading the stuff from a website. A lot of linux software is very high quality & free. For example there’s gimp which is a photo editor & blender which is a 3d modelling…

awesome post about RAM

Originally posted on More Than Tomorrow Project:

When you attempt to boot your computer does it answer you back with a series of cryptic beeps? Does your PC randomly shutdown at in opportune times and for no apparent reason? Are you occasionally greeted with a blue screen and white typeface that posts an indecipherable message, or a screen that grossly distorts images which normally render nicely?

If you answered “yes” to one or more of these questions then your computer’s memory may be slipping.

(Before proceeding, let us first clear up what we mean by “memory” and briefly describe the vital
role it plays in the function of computing devices. “Memory” is a generic term for Random Access Memory {RAM}, and is a form of short-term data storage. In essence, RAM serves to “juggle” the multiple tasks you ask your computer to perform while powered on, allowing for faster performance. When your computer is powered off those…

How to run an operating system without a CD or DVD

Sometimes we are working with machines that just do not have CD or DVD drives installed into them. What am I supposed to do in a case like that? Well thankfully there are options.

One of those options is to run your operating system of choice from a USB drive. There are a number of programs that you could use but this time we will talk about one that am quite fond of and that is Unetbootin. I know it has a funny sounding name but it is so very useful and easy to use as you shall see.

Now 1st of all you will need a USB drive unless you already have one that is available to use for this purpose as it is best that it has nothing else on it. I’d say 8GB or greater would be good, as you want to have space for the OS itself as well as programs and other data.

Insert USB drive into PC or Laptop and allow it to load up, once that’s done then  download Unetbootin from this site. Then you will need what  an .iso file. Now an .iso file is really the same information that would normally be on a CD or DVD, but supposed you just don’t have the operating system already burned onto the optical media of choice, well you can still use it directly by after the instructions of this post.In fact you could take a look at this for another example of how to do this a bit differently.

OK now the instructions are very straightforward you choose the operating system you wish to use and it will install it directly onto your flash drive. Now you will be able to boot it up from there, but first you must go into what is the  BIOS, and I will be discussing with you how to do that soon.


such a great post

Since I’ve started a new job as a PhD student, I am doing my best to become a proper nerd. I have switched from Windows to Ubuntu, and I have been testing many software applications under Ubuntu to find alternatives to what I’ve been used to. Here’s a list of what I am currently using for which purpose. I try to stick to open source software. If you click on the link, it will open in a new window/tab. So far I am very happy with my choices.

  • FreeFileSync – syncronizing data between computers. Simple and robust tool.
  • Krusader – file management made easy!
  • Mendeley – managing, sharing and indexing research papers. Makes referencing a joy. And you can share papers with your group online as well.
  • JabRef – reference manager integrated with Mendeley.
  • digiKam – photo management. i used to miss the Windows Live Photo Gallery. But now I’ve…

I can heartily recommend the Zorin OS, the Ubuntu based respin.  Everything works out the box much like Ubuntu except suspend.  A word of warning there is no upgrade feature unlike Ubuntu.  So may make sense to run LTS as all data will have to be manually backed up before a fresh install, reinstalling all apps.  However it is looking very slick & certainly offers more eye candy than the Xubuntu it replaced.

I chose Zorin OS for it’s mimicking of the XP desktop environment (DE.)  Although not a true clone (shame, but probably illegal) it may ease certain user’s transition from XP forward.  The main advantage being one of speed over sluggish XP on identical hardware, with the possibility of an SSD upgrade (more speed.)  XP will never support TRIM as it was not conceived at XP’s genesis & running an SSD is by way of messy hacks (as far as I can gather.)

great article, you will learn a lot from it!

Originally posted on Opus Magnus:

As I’ve alluded to previously, I’ve been exploring Joyent’s SmartOS lately. I’d like to talk a little bit more about it. It seems to me that a lot of my peers haven’t yet heard about it, or don’t really understand it much at all. The documentation isn’t really there yet, so I think that it is a little hard to get the right first impression if you’re coming into it with no Solaris background.

That’s right, I said Solaris. SmartOS is not Solaris, but it shares a common heritage with Solaris. SmartOS is based on the Illumos kernel, which is based on the OpenSolaris project (which no longer exists). Oracle has since closed the Solaris source, and most of the best engineers have found themselves reuniting under the Illumos banner. Many of them are under the employ of Joyent and Nexenta.

Apparently next year we will be able to buy a TV that has the Ubuntu Linux OS on it (a version optimized for TV)  with an interface based on Unity.

Nice one for Canonical.

P.S. : Here is a demonstration of the new interface.
