require 'benchmark'
n = 5000000

puts "convertions"
Benchmark.bm do |x|
 x.report("rescues") { n.times do   ; true rescue ''; end }
 x.report("ifs") { n.times do   ; raise '' if false; end }
end

The results

 
user     system      total        real
rescues  0.880000   0.000000   0.880000 (  0.880214)
ifs      0.790000   0.000000   0.790000 (  0.791239)

You win 0.09 seconds per 5m requests.
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?

uptimed. It is similar to the utility that most of us have heard of, uptime, except that it runs as a daemon and logs the system’s uptime instead of just reading info that is lost on a reboot. Uptimed provides a secondary command called uprecords

I searched audio driver on realtek website and latest HD driver are working fine with windows 7.

I found toshiba alps touch pad driver and it is working fine. Scrolling is now working fine with touch pad.

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.

Usage:  ./inc.rb in the current directory with all db files.

#!/usr/bin/ruby

Dir.glob("*.db") do |file_name|
 new_zone = []
 File.open(file_name) do |file|
 while (line = file.gets)
 line.chomp!
 if line =~ /Serial/
 line =~ /(\s*?)(\d+)(\s*?)(;.*)/
 serial = $2.to_i
 serial += 1
 puts "#{file_name} serial line:  #{$1} #{$2} #{$3} #{$4} -> #{$1}#{serial}#{$3}#{$4}"
 line = "#{$1}#{serial}#{$3}#{$4}"
 end
 new_zone << line
 end
 end

 File.open(file_name, "w") do |new_file|
 new_file.write(new_zone.join("\n"));
 end
end

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.

The client was very happy because he can imagine his website.

Now I am considering to buy or make such nice tools :)

1. Pencil

Pencil (free) is a Firefox plugin that professes to enable you to build wireframes and prototypes. As a prototyping tool it’s quite good, allowing you to quickly put together a reasonably high fidelity mockup. However, be aware you’ll still need to produce the visual design elements for Pencil, as it relies on dragging and dropping pre-made graphical elements.

The output wireframe elements that ship with Pencil do tend to be based on the look and feel of a Windows desktop application. This really is undesirable for a web application, however you could modify this with your own page elements.

Another downside of Pencil is that its export functionality provides only a few image formats. This means that Pencil falls short of being a real interactive prototype development tool.

Balsamiq Mockups

Balsamiq Mockups (price:$US79, demo available) is an interesting product running on Adobe AIR. Its representation of the interface elements has a refreshing hand-drawn, sketch-like quality to them. This does help promote the degree of changeability of the wireframes, as they look very much like a draft. If you lack the skills to create hand-drawn sketches then Balsamiq is a useful tool, as it allows you to produce quality roughs. Balsamiq also offers a standard collection of interactive screen elements, which is helpful to start off with.

http://gomockingbird.com/ is like balsamia

https://www.jumpchart.com/ – for very simple pages- I cant find how to change the layout.

When you catch a junior in mistake – let him contribute to the open source community. Not with coding. With translating. Take some open project and translate it to your native language.

Maybe after all the junior will release that he is much happier to translate than coding :)

win-win condition.

N.B. On the picture – Young coder is coding in Word.

Currently to start with Rails you have to learn a lot of stuff which are added just now and is not sure how long they will stay.

Also Rails is not targeting the developers to be fast but is targeting to be the perfect framework.

The price for that is that almost a year and a half there is no new version while the they refactor it.

No goodies like scafolding, only enterprise stuff around.

That is my personal opinion on this framework.

As I like to say – you cant leave your followers without food for such long time.
