one reason more to dislike svn

Fri, 03 Feb 2012 10:07:00 +0000

Before shooting me for all the rational reasons to have your code under source control .... Listen:

- Any developer should have 100% control over the source code of the instance of the project he is working on
- Any binary messing with that control is EVIL. Perioid

I have seen it with Microsoft Visual Studio. I saw it today with svn  - it messes the permissions of the projects so that you will not be able copy , move or edit FULLY from your source root dir and bellow.

And because of this EVIL I do have the templatize feature in the morphus project, which might introduce rare nasty bugs from time to time but provides me with independance without hiding and EVIL.

how-to setup non-password requiring connection between a win and *nix box with putty ...

Thu, 12 Jan 2012 11:48:00 +0000

1. Install Cygwin
2. Install separately the ssh-keygen ( or sshd ) on cygwin
3. Download the puttycfg , unzip to a dir in your Windows path
4. Find out where cygwin1.dll is installed cygcheck -sd >list.txt
5. Open the list.txt ( it is quite big ) : notepad list.txt
6. Copy all the files from   C:\temp\something  to the dir where the cygwin1.dll is located
7. Start the putty.exe : Start - Run : cmd /c START  /max putty
8. In the GUI , check that Session on the Left is selected , click on Cygterm option , for hostName type - , leave port number 22
9. Open the puttycfg :
10. Generate the public and private key's :
11. ssh-keygen -t rsa
12. Type Enter,Enter
13. Now here is the tricky part you have to tell also putty that the public and private key files are the one you want to use with you : Copy the /home/<>/id_rsa and ..id_rsa.pub to the dir where your save your putty conf in my case: C:\Temp\ysg\conf\<>\putty\ssh
14. Start - Run - type puttygen
15. Load the copied private key file and save it as <> , save also the public key file
16. Copy the id_rsa.pub file to the server's ~ dir
17. cp -vr /home/username/.ssh/ .
18. On the server cat id_rsa.pub >> ~/.ssh/authorized_keys
19. Now when started from the windows client :
cmd /c START  /max putty  username@servername.domain.com no password should be asked

bad software design sucks !?

Mon, 26 Dec 2011 21:47:00 +0000

Why ?
Because it does not reflect the real-world properly.

Think about the guys having designed the statistical software for USA


"A prominent example is President Barack Obama’s decision to not identify his multiracial ancestry on the 2010 Census Survey. Half white, Obama selected the “black” box option."

, BUT HEY WHAT ARE THE OPTIONS ?

So they are checking the “white,” “black” or “Asian” boxes.

Give me a break!!! The most multi-ethnical country in the world, and the db designers did not bother to put some more options ...

Edison vs . Tesla

Fri, 16 Dec 2011 20:36:00 +0000

It is strange that the famous quote from Thomas Edison :
"I have not failed, I've just found ten thousand ways that won't work."

gets entirely new meaning after the words of his worst non-business competitor Nikola Tesla about him:

He had no hobby, cared for no sort of amusement of any kind and lived in utter disregard of the most elementary rules of hygiene  ... His method was inefficient in the extreme, for an immense ground had to be covered to get anything at all unless blind chance intervened and, at first, I was almost a sorry witness of his doings, knowing that just a little theory and calculation would have saved him 90 percent of the labor. But he had a veritable contempt for book learning and mathematical knowledge, trusting himself entirely to his inventor's instinct and practical American sense

[string]Matches exactly one character that is a member of the string string. This is called a character class. As a shorthand, string may contain ranges, which consist of two characters with a dash between them. For example, the class ‘[a-z0-9_]’ matches a lowercase letter, a number, or an underscore. You can negate a class by placing a ‘!’ or ‘^’ immediately after the opening bracket. Thus, ‘[^A-Z@]’ matches any character except an uppercase letter or an at sign. \Removes the special meaning of the character that follows it.
