In the era of increasing gas prices everybody are interested how to increase their MPG (miles per gallon – used in USA) or respectively decrease gas consumption l/km (Used in Europe and most of the world).

This is not a simple task and it is mostly a function  of how car is driven. Here are some tips.

  • Take a look at car consumption that manufacturer put in your manual. Usually this is the optimum value you can reach – so inform yourself about it before you buy the car.
  • Try carrying as less as possible “useless” stuff in your car – heavier your car is more it will consume
  • Avoid putting stuff on the rooftop such as car-tops if you do not need them.
  • If you have 2 cars try to use them appropriately – do not use SUV for your shopping when you can do it with your hatchback (SUV consumes usually 2+ l/100km more than compact class car)
  • Maintain your car according to manufacturer instructions – inflate your tires to nominal pressure, change your oil regularly,replace your air filter, maintain your ignition system (change spark plugs and cables) etc.
  • Do not use A/C when you can open your window
  • Do not drive on highway with full open windows – This will break car aerodynamics (true for 60km/h+)
  • Do not speed – most of the cars are manufactured to be fuel efficient at the speed around the speed limit and if you drive faster you consumption increases.
  • …..

Some of those “tricks” are common sense, but thinking about them when driving will allow you to safe money….

In addition to be annoying and time consuming some of telemarketers are real crooks. According to here are six signs to recognise fraudent telemarketer and best action is to say thank you and hang up.

  • Demanding that you act immediately or else miss out on this great opportunity….
  • Promising that you can win money, make money, or borrow money easily…
  • Refusing to send written information prior to your purchase or donation
  • Trying to scare you into buying something
  • Insisting you wire money or a courier will come by to pick up your payment
  • Refusing to stop calling after you ask them to stop.

If you recognize one of those signs better say “NO, THANK YOU” and hangup.

Scientifically predicting the weather is something really hard, and you need a lot of information and powerful computers to do it. So how our grandparents were able to predict weather without watching TV forecast.

wikiHow published interesting article of how this could be done.

Google is adding more apps to his Linux repository.

They also have script to setup repositories, but unfortunately it does not recognize CentOS and yum enabled distribution. I’ve added this code to check if yum is installed:

# Check if yum is installed RHEL v5 and CentOS 4.x and 5
if [ '/bin/rpm -q yum' ]; then

Resulting script is here:

Google repos for centos

NOTE: After downloading the file just rename it from .txt to .sh and run with the shell:


Currently you can find there only picasa and google desktop

I use wine from rpmforge repository.

It works well, but all system (bitmap) fonts are missing. DAG could not confirm this as bug, but several other CentOS users confirm that this problem exists.

How to fix:

Install wine (You need rpmforge repo enabled)

yum install wine

Install msttcorefonts

Follow these instructions

move /usr/share/wine/fonts to fonts.old (if already exist remove c:\windows\fonts folder too)

cd /usr/share/wine

mv fonts fonts.old

It is done.

You can use wine and all fonts appear.

Recently site went down and this broke my YUM. Here is the error:

Setting up repositories
Could not retrieve mirrorlist error was
[Errno 4] IOError: <urlopen error (-2, 'Name or service not known')>
Error: Cannot find a valid baseurl for repo: rpmforge

As a solution I’ve edited manually my /etc/yum.repos.d/mirrors-rpmforge

vi /etc/yum.repos.d/mirrors-rpmforge

And commented out problem site.

Then edited /etc/yum.repos.d/rpmforge.repo

vi /etc/yum.repos.d/rpmforge.repo

And commented live list and uncommented file. Like this

#mirrorlist =
mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge

Now YUM it is back. Still get some mirroring errors, but at least I can use it.
