SerbDict—Serbian-English Dictionary (serbdict.sourceforge.net)

I've highlighted a few language programs in this column, but so far they've been for Japanese, Chinese and German—all languages spoken by large populations. So a dictionary program for a language like Serbian jumped right out at me. According to the SourceForge page: “Serbian Dictionary is a bidirectional Serbian-English dictionary. It currently contains only a command-line interface. It supports only *nix-based operating systems at this moment. Tested on Linux, *BSD and Cygwin.”

SerbDict lets you translate words from English to Serbian and vice versa.

Here's a search involving Serbian to English and a search involving both languages simultaneously.

Installation

I found only a source tarball at the Web site at the time of this writing, although the installation still is quite easy. Also, the home page is in Serbian, and I had to use a translator (Chrome's translator handled this well). The download page at least is called “Download”, so that was easy. The download page takes you to a basic SourceForge file list, which should be localized into your own language.

Grab the latest tarball, extract it, and open a terminal in the new folder. Compiling this program is easy, just enter:

$ make

If your distro uses sudo, enter:

$ sudo make install

And, if your distro uses root, enter:

$ su
# make install

Usage

Using SerbDict also is very easy (at least, once I'd translated the documentation). If you want to translate something from English into Serbian, enter:

$ serbdict -e word

If you want to translate a Serbian word into English, enter:

$ serbdict -s word

SerbDict appears to query a database of words and terms, and it outputs everything, including extensions of your queried word. For instance, querying the word “entire” gave me not only translations for entire, but also for entirely and entirety.

If you speak Serbian (and I don't), there's a man page with instructions on how to extend the program, available with the command:

$ man serbdict

One thing I managed to pick up from the man page is that if you skip the -s and -e extensions, any query you make will output any matches in both English and Serbian at the same time.

Below your outputted text will be a message saying, “Ukupno: x prevoda”. After querying those words, it turns out Ukupno means altogether. And although “prevoda” didn't return any matches, prevod means rendering, translation or version, so I'm guessing prevoda would be some kind of plural form of these words.

Well, that covers Serbian, but if anyone has written a program for a really rare or dying language, send me an e-mail. I'd love to cover it.

ebook2cw—E-book to Morse Code Conversion (fkurz.net/ham/ebook2cw.html)

You know I love niche projects, but this is the first project I've come across that genuinely made me laugh out loud and exclaim, “I've got to cover that!” To quote the Web site: “ ebook2cw is a command-line program (optional GUI available) that converts a plain text (ISO 8859-1 or UTF-8) e-book to Morse code MP3 or OGG audio files. It works on several platforms, including Windows and Linux.”

Turn e-books into Morse code audio tracks—I'm guessing this is intended for Morse code students.

Installation

Quoting the documentation:

1) Binaries: statically compiled binaries are available at the project Web site, for Linux (i386) and Win32. Those should be suitable for most users.

2) Source: a Makefile is included; it compiles both under Linux and Windows (with MinGW).

Library requirements are mostly minimal, but for the source, you will need the development packages (-dev) installed for the lame and ogg libraries.

If you're running with the source, grab the latest tarball, extract it, and open a terminal in the new folder. Compiling this program is also easy. Again, just enter:

$ make

If your distro uses sudo, enter:

$ sudo make install

If your distro uses root, enter:

$ su
# make install

Usage

ebook2cw is a command-line program and using it is fairly simple, although you'll want to keep the man pages at the ready for using something other than the default parameters. The basic syntax is as follows:

$ ebook2cw textfile.txt -o outputfile

Here, the textfile.txt obviously represents whichever text file you want to convert to Morse code. The -o switch is for specifying the output file, followed by the output file's name. Notice I haven't given the output file an extension, such as mp3. ebook2cw does this for you automatically, and I actually recommend against doing so, as the resulting filename becomes rather messy.

I don't have the space to go into detail on ebook2cw's command-line switches, but I can at least highlight a handful that will be the most useful to the majority of users.

If you want to switch from MP3 output to Ogg, use the switch -O (note the uppercase letter).

The sample rate is set by default to 11khz @ 16kbps—perfectly adequate for a series of dots and dashes, but sometimes it's a bit clippy and horrid to listen to. If you want to change the sample rate to 44khz, for instance, use the switch: -s 44100. To change the bitrate, using this combination, set the bitrate at 64kbps: -b 64.

You can work things out from here, but I hope you enjoy the results. Maybe the works of Dickens are even better, slowly spelled out one letter at time? Either way, this project has probably given me the biggest grin since I started this column. I'm sure it'll be very useful—to someone.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
