uCareSystem and uCareSystem Core v1.0 released

As you may have already read the Story behind uCareSystem one missing piece of puzzle was a terminal version of uCareSystem for all of power users and server administrators out there.


uCareSystem Core

You will find the new uCareSystem core executable in the same folder as with uCareSystem.

This, terminal version is for: – Experienced users or Powerusers – Non Desktop Environments – Servers – Workstations — for Adminstrators who want silently to make some system maintenance – Using with Cron Jobs by Admins for scheduled and automatic system maintenances


uCareSystem Core has the same functionality with uCareSystem but without it has no GUI.

Also, the first time you run the uCareSystem Core, it will copy its self to your system so that the next time you don’t have to run the executable again. You will need just to run :

sudo updatecore

So what are you waiting for ! Head over the Download Page>>>

Optimus Kernel released

After the recent change on release schedule, you can download the latest version of Optimus Kernel which is based on the following recipes :

  • BFQ patches
  • In-house optimizations

Go Grab your Packages from the Download Page>>>>>

Optimus Kernel Change log:

New course, new opportunities…

After 9 releases of Optimus Kernel while the release cycle was going smooth and I was releasing following the mainline kernel version…. in June after the release of Optimus Kernel 3.3.7 things started to slow down on the schedule because of some factors. This led me to reconsider the release cycle of Optimus.

If you want to read the full story behind my decision please read the detailed blogpost over my blog :

Optimus Kernel: Building the best Ubuntu Desktop experience

Here its the TL;DR version:

  • New versions will be based ONLY on the latest available stable of Ubuntu
  • 100% Compatibility is unquestionable
  • Linux Kernel from 3.3.8…. 3.4+ caused some build errors that where time consuming το fix
  • Came across multiple Bugs in BFS and BFQ schedulers
  • Patches to make an Ubuntu compatible Optimus Kernel that is based on the latest Kernel, are not always at sync with mainline (at least not stable)
  • New Optimizations will focus more on Performance
  • Stability is priority so users should feel the same as using the default kernel that ships with Ubuntu but feel the boost in performance

Please stay tuned, by subscribing and the following days I will release the 64bit and 32bit versions of Optimus Kernel based on this new release schedule.

Optimus Kernel 3.3.7 released

You can download the latest version of Optimus Kernel which is based on the following recipes :

  • Linux 3.3.7(if you have proprietary graphic card drivers installed in your system you may need to reinstall them after the installation of the new kernel release)
  • Ubuntu/Debian patchsets
  • BFS and BFQ patches
  • In-house optimizations

iQunix 12.04 released: New course and new plans

A brand new release, iQunix 12.04 is available for download. Alongside with this new release there are some new plans for this special OS. iQunix OS has been around for about a year. With this release there are some major changes and plans for the future. So in general iQunix:

Whats new:


iQunix 12.04 is now based on Unity, the latest user interface that Ubuntu introduced earlier in 2011.

Appart from the overall user interface change there is:

  • JetBrowser: It is the new addition in Utappia’s portfolio, a really fast, simple and secure browser
  • Software Center: Thousands of applications one click away.
  • Gedit: Simple to use text editor
  • Remastersys: You have installed some applications and you want to share the resulted OS with your friends or you want a complete backup ? This the app for the job.

Apart from the above there are no other unnecessary software, so you can install what ever you want.

What else :

The iQunix 12.04 will be supported with software and system updates for 5 years. This means that you install once and have it for 5 years. Also the ISO files that is available for download, will be updated with the latest updates, so that if some time later on the lifecycle of iQunix 12.04, you need to re-install, you will have an up-to-date ISO.

So you want to try ? Go grab the ISO>>>>>>>

Installation of iQunix is the same as Ubuntu. You can reade the instructions here

I wish to thank all of you who are donating for the development of iQunix.

I wish you the best.
