In the last seven months I learned git, working for a dozen of projects. On some of them I was the master&commander, on others I only set up the streams and let the young Jedi find the way to the delivery. Via trial and error I find out a bunch of userful commands.

ForceBindIP is a freeware Windows application that will inject itself into another application and alter how certain Windows Sockets calls are made, allowing you to force the other application to use a specific network interface / IP address. This is useful if you are in an environment with multiple interfaces and your application has no such option for binding to a specific interface.

via ForceBindIP - Bind any Windows application to a specific interface.

In a nutshell, xargs is an alternative to fully expanded shell for loops. Given the right options, xargs can be made to exhibit for-loop-like behavior. But out of the box, it is a way to pipe a bunch of arguments to a single command in one fell swoop.

This can save a great deal of compute time if you are piping a long list of arguments to a command rather than iterating over them one at a time.

In  A small primer on xargs you will find a deep explanation on xargs usage. The article teach me a bunch of tricks I am not aware of (and I know Unix from ‘93….yes, 1993…).

Negli ultimi mesi ho sviluppato un motore di ricerca per il codice, chiamato code zauker.

Lo ho scritto in Ruby e Redis. Ruby è un linguagio che conosco da tempo, ma housato molto poco. In questeultime settimane ho voluto riprendere in mano Erlang, e per esercizio ho provato a riscrivere il kernel del motore di indicizzazione in Erlang, creando ErZauker

Replacing on entiere set of files is hard in Emacs. But I find the correct mumbo-magic procedure, and gifted it to you:

• Call dired to list files in dir, or call find-dired if you need all sub directories.
• Mark the files you want. You can mark by regex by typing 【%m】.
• Type Q to call dired-do-query-replace-regexp.
• Type your find regex and replace string. (➲ common elisp regex pattern)
• For each occurrence, type y to replace, n to skip. Type 【Ctrl+g】 to abort the whole operation.
• Type ! to replace all occurrences in current file without asking, N to skip all possible replacement for rest of the current file. (N is emacs 23 only)
• To do the replacement on all files without further asking, type Y. (Emacs 23 only)
• Call ibuffer to list all opened files.
• Type 【*u】 to mark all unsaved files, type S to save all marked files, type D to close them all.

And so you was waiting for news?

Nice to impress you: I was able to shot two code zauker versions in less than a month!

Code Zauker, the yet-another-google-code-indexer  based on redis is happy to impress you with new features:

• Better web interface
• Powerful multi-processor indexer (mczindexer)
• Better documentation on the readme on github,  con ready-to-use example.

Code Zauker is schema-free and need no special setup on redis: just run the indexer and enjoy. You can also point to non-local redis server using password authentication, for extra security.
