Renaming files
I've decided to put here different examples of tasks to resolve them by scripting.
1) Rename the pool of files with same beginning of files by cutting the same beginning part.
For example, we have
Pimsleur - English For Russian Speakers - Unit 01.mp3
Pimsleur - English For Russian Speakers - Unit 02.mp3
.....................................................
Pimsleur - English For Russian Speakers - Unit 30.mp3
We should get
Unit 01.mp3
Unit 02.mp3
.....................................................
Unit 30.mp3

LSF issues: RAM and swap
It were interesting workdays last week due to a lot of users began submit jobs to LSF. It was my first week after annual vacation :) And it was my first little experience of troubleshoting LSF issues.
One user submited calculation of big model in DYNAMO and sent to down two nodes of LSF with message "Out of memory". It were IBM x3550 with 32GB RAM and 8 GB of swap. Support suggested us to increase the swap memory and to try after that. I increased swap memory to 32 Gb by adding into swap files from filesystem () and we tested with user. He submited his job which consumed all available RAM and more than 20 Gb of swap.
But it successfully finished!
Other user could not finish his model after 4 or 5 hours of processing. And I did not suspect that problem was in unavailablee free space on his disk partition.
So I have got two things - at first check possible lack of RAM and swap and lack of disk space.

Мегафон в Meizu
Купил Мейзу и никак не удавалось настроить жопарез. Нашел ссылку http://img229.imageshack.us/img229/3950/prtscn20090707183550.png , где прокси прописан и порт 8080. Хотя в контакт-центре по 0500 ответили, что нужно без прокси настроить и с именем/паролем gdata/gdata. Сделал прокси как на скрине, но имя/пароль и gdata/gdata заработало ... :) Т.о.

Имя - gdata
Пароль - gdata
