Delete outlook mails

Unfortunate chain of events during some testing conducted by my colleague led to a full folder in my outlook. When I say full I mean ~7M emails generated during test that lasted a couple of minutes.

Python to the rescue (outlook needs to run during this operation)...

Elixir and Phoenix, love at first sight

These days I am reading a lot about Elixir and Phoenix. I still didn't have the time to try them out but I fell in love by just reading the texts. Read this and this and tell me, doesn't it sound beautiful?

I have a bunch of materials that I gathered during the years that would help me switch to functional programming. The only peace from that pile that I invested more time was SICP which I would warmly recommend. That other stuff is just collecting the dust :)
I hope Elixir/Phoenix combination will help transition.

[EDIT:] And apparently, the whole thing is on fire. Just 5 minutes after I published this post it has 5 views. <3 p="">

Deleting many files, ubuntu server terminal vs win7 command line

We created a lot of garbage log files in our last project. ~60k files taking 2GB of space.
Ok, let's delete some of them. I don't need those xml files so I backed them up and I tried:

view plainprint?

1. rm *.xml  

rm *.xml

view plainprint?

1. Permission denied  
2. Permission denied  
3. ...  

Permission denied
Permission denied
...

Ok:

view plainprint?

1. sudo rm *.xml  

sudo rm *.xml

Everything goes ok.

view plainprint?

1. ls  

ls

~60k files still here?!? WOOT?
I had to delete them in groups that are smaller than 10k files.

view plainprint?

1.  sudo rm 21*.xml   

 sudo rm 21*.xml 

It worked
Let's try the same thing with another OS:
Extract backup to win7 machine. Go to console. Try:

view plainprint?

1. del *.xml  

del *.xml

Files are gone!

Migrating SVN with history to a new Git repository

Thx to stackoverflow.com thread and a post from user Casey I finally did it.

Follow instructions given by Casey and add few steps.

Here are the steps to add to save all branches.
do:

view plainprint?

1. cd dest_dir  
2. git checkout -b local_branch remote_branch  

cd dest_dir
git checkout -b local_branch remote_branch

for every branch after step where you cloned:

view plainprint?

1. git clone dest_dir-tmp dest_dir   

git clone dest_dir-tmp dest_dir 

before step where you removed temporary dir:

view plainprint?

1. rm -rf dest_dir-tmp  

rm -rf dest_dir-tmp

Installing skype

I tried to install skype yesterday. It's a nightmare.

1. www.skype.com
2. Follow "Get skype" link
3. Follow "Get skype for windows" link
4. Follow "Download skype" (3rd page and it still does not start!!!)
5. Site says something like: "You must login/register" WAT?!?
6. Forgotten your password?
7. Follow mail link
8. Enter new password
9. I enter something like "ExtrAComp1ic4t3dPassvvorD1234"
10. Site says something like: "Your password is too weak"
11. I enter "ExtrAComp1ic4t3dPassvvorD1"
12. Site says something like:"You can download now."
