Linux server in the form of a network adapter

Wednesday, January 14th, 2009

Linux

A server, which is ready to work by the insertion into the socket is difficult to imagine. At least until you don’t know about the server from SheevaPlug.
The server of SheevaPlug has a very compact design, that is very similar to the network adapter.
Under the hood of this device you will find 1.2GHz processor, 512MB flash memory and 512MB of RAM memory also. It has also the following external connectors:
1. USB (2.0)
2. 1Gbit Ethernet

Hard to imagine, but this server consumes only 5W of power.
The device costs only 99 $ and I suspect that in the future these devices will be more cheaper.
I would buy it, if I had no any server. But I have a server at 1&1 :)

SVN setup in Linux

Tuesday, December 16th, 2008

Because I spend a lot of time by programming exercises with other students in a group, I thought after a year of study about how to improve the efficiency of the work. Because we can’t always sitting together in one place, we work most “remote” and that’s why we have a board based on PHPBB 3. It is very convenient, because we can place our source codes there and exchange ideas and ask if someone of us have a problem, we can describe those problem on board and discuss it. After the exercises steadily gained in complexity, we found unfortunately that the publication of several source codes of Java or C+ + classes, no longer so feasible as before.
That is why I wanted to try a system like subversion. My choice was SVN, because CVS compared to SVN is technically much better.
The installation and use of SVN is very well documented. There are many HowTo’s, as well as tutorials which explain how Subversion works. The most important of all this documentations is the book “Version Control with Subversion”. The book is available on the Internet for free and explains pretty much everything what you could need to know about setup and use of SVN.
If someone use Eclipse development environment, I can give you a tip about the SVN plug-in for Eclipse. The plug-in is called Subversion. This plug-in is much better then Subclipse and it is integrated in the Eclipse project. The only thing that you need to get from an external source is a connector for subversion. But those connectors are free and you can download them from the web page of the developer.

Gnome 2:24

Monday, September 29th, 2008

As Heise.de reports the new version of desktop graphic environment for Linux Gnome 2:24 were released today.
Basically, there were no major changes. When you read release notes (http://library.gnome.org/misc/release-notes/2.24/), you will find out that there really are no major changes were, but several smaller ones. There were hundreds of bugs eliminated, including:

1st Pidgin is exchanged by Empathy (both programms look is terrible):

Empathy also supports XMPP/SIP audio and video conferencing as available on the Nokia N800/N810 devices (video requires H.263 codecs for GStreamer to be installed). Empathy is a great companion to Ekiga, GNOME’s audio/video SIP client (see Section 2.3 ― Ekiga 3.0).

2nd A new utility to monitor the working time has been added:

For many people in business, it is crucial that they track how much time they assign to each project and client. Everybody has their own system for this, from keeping a diary to making a guess. It’s incredibly tedious. In today’s world almost everything you do somehow involves a computer, so GNOME has added a panel application to make tracking your time easier.

3rd Ekiga in version 3.0 presented:

Ekiga is a fully-featured SIP audio/video conferencing client for GNOME. As part of GNOME 2.24 we’re proud to announce the release of Ekiga 3.0.
As well as a new interface that is centered around your phone book and the presence of your contacts, Ekiga 3.0 features SIP presence support, PBX line monitoring, better video codecs support (H.264, H.263+, MPEG-4 and Theora), accelerated video and optional fullscreen and many SIP-related improvements for robust conferencing.

4th Changes in the file management:
As well as icon and list views, GNOME 2.24 now offers the compact list view, popular in several other desktop environments. Choose the view by selecting View ▸ Compact from the menu (or keyboard shortcut Control+3).
As with icon and list view, the size of the icons in the compact view can be changed using the zoom options in the View menu.
The browser mode of the file manager now supports tabs for rapidly switching between directories within a single browser window.
Today’s modern filesystems are able to handle almost any desired character as part of the filename. Unfortunately this is not the case for the FAT filesystem that is commonly used on many USB thumb drives and portable music players, which is unable to use many common punctuation marks as part of the filename. GNOME 2.24 detects when you are copying files with names that contains characters that cannot be used and automatically converts these characters to a “_” without you having to rename the file yourself.
Automatic filename completion (“tab” completion) has also been improved in GNOME 2.24. Completion of filenames in the location bar using the Tab key is now faster and more predictable. It is also possible to complete any fragment of the path and the interface provides more feedback for when there are no other possible matches available.

5th Deskbar gets more senseless features:

The Deskbar in GNOME 2.24 adds several exciting new plugins: a calculator, Google Search (and code search), Yahoo! and Wikipedia suggestions plus updating of Twitter and identi.ca

6th From now on Linux, you can connect multiple monitors and better than ever manage:
More and more computers (especially laptops) are gaining support for multiple monitors (known as multihead). Users need to be able to connect a second monitor, either as a clone (e.g. a projector for giving presentations) or as an extension of their desktop.
7.Sound Themes:
Sound themes in GNOME are now handled by libcanberra, which implements the Freedesktop.org Sound Theme and Naming Specification. Sound themes can now be installed like icon themes. Using libcanberra also means that an application’s alert sounds are less likely to interfere with your music player or movie player, so you can leave those important alert sounds switched on while watching a fullscreen movie.

8.Better support for DVB:
Powered by the GStreamer multimedia framework, GNOME 2.22 introduced digital television (DVB) capabilities into its Movie Player. Determined to make things even better, developers have worked to enhance this support by adding support for multiple DVB tuners (watch multiple channels at once) and better troubleshooting diagnostics.
They have also worked to improve out-of-the-box (zero configuration) support for the majority of infrared remote controls (using the LIRC framework). This makes it even easier to chill out instead of writing that important report.
Also featuring in GNOME 2.24, support for high-resolution YouTube videos and support for remote (non-local) text subtitling.

9.Neue background graphics
GNOME wants to make your computer look good, which is why we work hard on our themes and artwork. For GNOME 2.24 we ran a competition to collect some of the most intruiging desktop backgrounds our contributors have produced and we’ve shared our favorites with everyone.

There were also some changes that sould improve accessibility, some changes for the developers and improved localization.

Beryl + Emerald Theme Messenger

Tuesday, May 22nd, 2007

Some time ago I told my friend about my change to Linux. He gave me a link to video on YouTube about new 3D desktop for Ubuntu Edge.
Some related video I saw in internet many months ago. It was a Novell demonstration of the new technology.
Of course I was sold of it and I wanted to have it on my computer. But I needed a lot of time to configure it and correct all of the bugs.
Here are pages, where I found a good help:

Instant messenger for Linux

Sunday, May 6th, 2007

Ubuntu Edge has Gaim as standard messenger. My problem is, I don’t like Gaim, because of terrible design. The design of Gaim is so terrible that I could not find words to describe what I’m feeling while I see it. I’m not a designer, but I think that I could make it much better, that it is now.
The existence of Gaim on my computer was stopped with commad:
apt-get remove gaim

But there are not so many messengers for Linux that understand different code pages at the same time and looks like better than Gaim.
As alternative for Gaim I found Simple Instant Messenger (SIM).
SIM looks like as a normal messenger and has code pages choice so you can choose a code page while you are chatting.

Google Earth 4.0 for Linux

Monday, April 2nd, 2007

Unfortunately the most of developers, who are developing software for Windows and for Linux, concentrate the main power on windows applications. For example Skype offers their software for different platforms, but only Windows based version has all new features.
The reason of this behaviour is a dimension of windows community.
The one of good exception is a Google Earth 4.0. Google released all versions of their software at the same time.
The main new feature of Google Earth is a new possibility to view famous buildings in 3D view.
