The results

rescues  0.880000   0.000000   0.880000 (  0.880214)
ifs      0.790000   0.000000   0.790000 (  0.791239)

If you serve one page for 0.20 sec you have to made apx 10m page views and you will have one free as a reward of using ifs

But did you win? How ugly is your code?

Doing some research and I can’t believe Gnome3 has the same STUPID look as MacOS OMG!!!

What innovation  you see at copying the same OS from MAC. I remember the days when the Linux desktop looks innovating and it was pleasure to work with so many options. Now everything is going the Apple way.

I felt depressed is there around at least one windows manager which is not influenced from Apple?

I hate Dock launchers -  looks not innovating – it looks clumsy and old. Everything which is copied clumsy!

Gnome3 – you are going on the same path as Unity!

Windows7 – is 100 times better because it has its OWN LOOK AND FEEL – I’d rather work with windows7 than on a Gnome3/Unity. Blah!

The solution?

Xfce desktop is now closes to what Gnome was

strange keyboard – I remember how I laugh when microsoft put their logo on dedicated button on the keyboards – haha -> Apple

Usability – What are those fancy drawing on the keys, they look all the same to me, no way to rember them.

Fucked hardware – $60 for cable which cost less then $1 haha, no card reader.

Nice plastic case with big mouse pad.

I hate the way how MAC os wants to be different making some irritating changes – not revolution – only some small tweaks.

Apple Mac is for people which DON’T know how to work with computers

Seriozly this was the best IDE around for Ruby/Rails.

• RubyMine – is heavy and cluttered and it is not free
• Vim – is nice but it is NOT ide
• RadRails – is in some beta

Here is a list of alternatives on stackoverflow and some others

OMG! 1MB for a blog post. This is server/memory killer.

One more thing is that their API is total mess (very well documented) but still mess.

No error messages, no warnings, no blog.

I was doing Zen for 3 months and today I have managed to restored all the posts.

I use my blog to store some useful notes to me and I hope that they are useful to someone else also.

Малко реклама:

Имам приятел, който е собсвеник на транспортно-логистична фирма.  Той имаше проблем с шофьорите си, които си правеха делавери с горивото на негов гръб. За да си реши проблема и да има стриктен контрол той реши да използва GPS системи за проследяване, мониторинг и контрол.

Много се чуди кой продукт да избере и след дълго проучване се спря на Webeye от които е много доволен. GPS системите на Webeye оправдаха неговите очаквания, първо защото системата позволява да се наблюдава всяко превозно средство и всяка точка от маршрута: тръгване, спиране, напускане на дадения обект, както и да контролира нивото на горивото, което включва измерване, презареждане и потреблението по време на път. По този начин имаше подробна информация за дейността на водача. В крайна сметка човека успя да постигне това което искаше, с което си спести доста излишни разходи.

Those keyboards are getting really challenge. I can’t imagine how a kid will repair his keyboard in 2019 year.

So….The for me it was really easy if because I have found this post here.

1. find a way to lock your screen
2. mount the parts on the keyboard! not on the key
3. Make sure that the little part of the deck-chair is mounted on first on the bottom parts of the laptop keyboard
   1. slide it from top to bottom to hold it firmly
4. The big part of the deck-chair will lie on top of the laptop keyboard mount. Then with shrink it a little so that it falls in the holes bellow
5. Next the put the key ontop of the already mounted deck-chair. but not exactly on top but a little bellow the middle point in a way that you can slip to down and above. This way the key will get mounted on the deck-chair (lower part). Next press it down to stick firmly the top part of the deck-chair.

PHP use one standard but those Symfony guys use another?!

You may wonder why the helpers are named according to the underscore syntax rather than the camelCase convention, used everywhere else in symfony. This is because helpers are functions, and all the core PHP functions use the underscore syntax convention.

I’ve got a few servers in different places around the country and try to monitor them using the logwatch utility.  One problem that I’ve run into however is that a few of these servers are not able to send their logwatch emails to me, based on email restrictions by the ISPs.  I spent some time this afternoon researching what was required to have my servers authenticate to my gmail account and send me the mail that way.  This setup assumes Ubuntu 8.04 (or later) and Postfix.

Install the required packages

sudo aptitude install postfix libsasl2 ca-certificate libsasl2-modules

Configure Postfix

This tutorial will not outline how to configure your postfix server, but we’ll jump directly to the relayhost section.  You’ll want to add the following lines to your /etc/postfix/main.cf file:

relayhost = [smtp.gmail.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_tls_CAfile = /etc/postfix/cacert.pem
smtp_use_tls = yes

The above lines are telling Postfix that you want to relay mail through gmail on a specific port, telling it to authenticate, and where to find the username and password.  The last three lines specify the authentication types supported, where the certificate authority file is and that it should use tls.

Define Username and Password

Next we’ll need to populate the sasl_passwd file.  Create the file /etc/postfix/sasl_passwd with the following contents:

[smtp.gmail.com]:587    user.name@gmail.com:password

This file should have restrictive permissions and then needs to be translated into a .db that Postfix will read.

sudo chmod 400 /etc/postfix/sasl_passwd
sudo postmap /etc/postfix/sasl_passwd


At this point you can restart Postfix and it should work, however it will complain about not being able to authenticate the certificate.  To take care of this issue we’ll use the ca-certificate package we installed and tell it where it can validate the certificate.

cat /etc/ssl/certs/Thawte_Premium_Server_CA.pem | sudo tee -a /etc/postfix/cacert.pem

Go ahead and reload postfix (sudo /etc/init.d/postfix reload) and you should be set.
