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.

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.

 

Don’t play the stupid game Cause I’m a different kind of  engine Every search sounds the same You’ve got to step into my world Give me all your RAM and give me your code Give me all your code today

A new, improved version of Code Zauker is out!

In my code ramblings during the developement of Code Zauker, I ended up studing a bit NoSql  database.

Code zauker started using Redis, because Redis is a very bold memory-based no-sql db. Redis also support complex data type like sorted set, lists and so on, which was very userful. Anyway I needed a very fast way of doing statistics on data collected by code zauker, for inspecting data and finding out new feature I’d like to add to it. Worst, my current pocket pose a hard limit on a redis instance in terms of available RAM. So I started thinking a lot about a redis drop-in replacement for Code Zauker.
