How much power my PC actually take – or – Why My Electricity Bill is so HUGE??

Like most people living in this new era my house have a large amount of electronics devices and as an IT guy I have about 5 computers (Laptops, PC etc) and 3 mobile devices.

I want to  tell you about one device particularly – my main home server. Few years ago I bought a small server called HP Microserver – low utilization and effective as basic linux server along side a good storage server (with raid).
Like most of my computer geek friends this PC was turned on day in and day out – just like every other PC I had before I just left it on – and it didn’t matter if it actually did something or not (and yes it did nothing most of the time).

A few months ago the little server went down and wouldn’t come out. When I’ve looked into it I’ve found out that it’s Power Supply was down.
And it took me about 3 months to fix that, why? Due to the fact that this Power Supply Unit was a unique one. It fitted directly inside it’s small case and was only 120W so it was not only less costly electricity wise it was also extremely expensive.

After 3 months I’ve found a cheap solution using a regular Power Supply (the 450W very cheap ones) with some of my modification.
But what I found in these 3 months was even more interesting: Continue reading How much power my PC actually take – or – Why My Electricity Bill is so HUGE??

24 Hours with my Healbe Gobe

About 2 Years ago I was really into Kickstarer/Indiegogo – I supported several projects (mostly comics or gadgets) some came threw (Makey Makey) some did not (Ringbow).
At one day I’ve found an interesting in Indiegogo called Healbe GoBe which was described as “The Only Way to Automatically Measure Calorie Intake” – That sound too good to be true! But alas I’ve decided to support and try to get my hand on the device and ordered it.

Now a year and a half after the promised delivery date I finally got the device – and have been wearing it for the past 24 hours.
then how is it? lets find out:

UEFI + GPT for windows – Why so difficult

The first time I’ve laid my eye on a server with UEFI was couple of years ago. My work place bought new IBM servers and they kept crushing down mid boot or taking a very long time to boot.
I asked myself why use this new replacment for BIOS? Why do we need it – especially back then when the UEFI was very young and not that stable.

The real reason back then (to my knowledge) was the Nehalem architecture which benefited faster boot, 2T+ hard drive support and better memory access.
As said I didn’t like it back then.

Don’t take me wrong – UEFI is the future Continue reading UEFI + GPT for windows – Why so difficult

32Bit in 64Bit world – or how to run Fortinet SSLVPN Client on 64Bit Ubuntu + Debian

In this new and limitless world we have 64bit cpu’s and OS (Even MinuetOS is in 64bit)
Some legacy programs insist on running in 32bit because well … the company don’t have the resources, legacy reasons or any other reason why not to (I have no real idea actually why).
Most of the new OS can also run 32bit in 64bit OS, for example: windows 64bit can seamlessly use 32bit programs without hindering. Linux on the same hand – can do that too.

So this makes me mad that despite that 64bit OSs and software; not only available for the major part of the last 7-8 years; but also in the last 4 years 64bit OSs and softwares are the majority (by far) in the industry, and yet some companies think it is O.K. to deliver only 32bit software.

Last week a colleague came to me and asked me about his 64bit Ubuntu 13.10 – for some reason the Forticlient SSLVPN Client just won’t start working. The result is unpleasant after trying to run the file, the error:

bash: ./forticlientsslvpn: No such file or directory

A little search in the internet explained that this is 32bit software and you will need to install 32bit liberaries.
My first response was – why? I’ll just login to the Fortinet site and download the 64bit version right? Wrong – they didn’t have any (but oddly for window they had 32 and 64 bit)
So ok I’ve tried to install the liberaries all the answers in the web said:

$ sudo apt-get install ia32-libs
.....
E: Unable to locate package ia32-libs

Wait? What? Why there is no package?
Rampaging through the forums and finally after 10 minutes I’ve got to a post saying – “Sorry folks – no more ia32-libs packages in Ubuntu 13.10 they removed it”
Wait what? What should I do now?
After alot oaf searching and a lucky guess I’ve decided to install gtklib 32bit – I recalled this is the one the Fortigate SSLVPN Client is using:

$ sudo apt-get install libgtk2.0-0:i386

That did the trick!
After the installation finished no more “No such file or directory” Error; now a new and more constructive error arise:

can't find libSM.so

Well that’s easy – little search and:

$ sudo apt-cache search libSM
....
libsm6 Description: ...
....
$ subo apt-get install libsm6:i386

I’ve continued  on until I’ve installed them all.
Finally after 5 more minutes the Fortinet SSLVPN Client was running!

The trick was easy:
After an error for library arose I’ve search the package containing it either with “apt-cache” “apt-file” or Googled it.
After I’ve found which liberary I need to install I’ll install it with the suffix of “:386” (so: <PACKAGE_NAME>:386) this the 32bit libs will be installed.

This trick will probably work for any 32bit software.

For the impatient one here is what you need to run in order to get Fortinet SSLVPN Client running is:

$ sudo apt-get install libgtk2.0-0:i386 libsm6:i386 libstdc++6:i386
Ubuntu 16.04 updates:

By Arnon (thank you very much!):

sudo apt-get install libcanberra-gtk-module:i386

It appears that ubuntu 16.04 have spread the files over more packages now you should add:

For those who use Debian you can follow this instruction:

By Debian – janjansen@dr.com (Thank you very much!)

Under Debian you need to do this first:

# dpkg –add-architecture i386
# apt-get update

The Jungle which is Roms for Android

I’m an android guy.
I’ve started small with Samsung Galaxy S, Then Samsung Galaxy S3, and now the Nexus 4 (all are company phones). I’ve also have Motorola Xoom and a small android for my TV I’ve got at DX.

With all these devices I’ve never changed their Roms – I say “if it works and works well why tamper with it?”
