Android developers can now slip native code into apps written for Android-based devices using Google's new native development kit (NDK). The Android 1.5 NDK, which was announced Thursday on the Android developers blog, doesn't actually allow developers to run completely native code on devices. Instead, it supports adding native code into apps written to run in Dalvik virtual machine (DVM) instances.

The middle of June, Yahoo! introduced a small change to its user login protocol that practically barred access from all Linux clients. IM services Pidgin and Kopete were hit and responded quickly. To protect its users from phishing scams, Yahoo! changed its login authentication protocol, as they announced June 16. The new protocol expected a specific authentication method version on the client end and refused access if it didn't match. IM services Pidgin and Kopete were recently affected by this.

htop - Undoubtedly the most famous of the top-like tools. It implements some extra options to the "top" command, like colors, ability to scroll horizontally and vertically, and a better interaction with the processes listed. nethogs - network information, but instead of displaying the traffic by protocol, nethogs shows the bandwidth usage by process. Very interesting.

In our 3rd post of our series on the efforts of OLPC, Santa Barbara, we will discuss the ways that the XO's have been used as learning tools our local 3rd grade classroom. Lets jump right into it...

Details of how Intel and Nokia will actually work together to create their brand-new category of not-a-smartphone, not-a-netbook mobile devices remain sketchy, but the first results will be open source software rather than any hardware platform.

Linux distributions designed for netbooks are a dime a dozen these days, so one really has to pull something extraordinary out of the hat to impress the mobile crowd.

Tomboy is an extremly handly note taking application for Linux, but I always found it annoying that it was so hard to sync across machines. With Dropbox, it’s amazingly simple.

It's doubtful that very many users enjoy reboots. Although system uptime is often worn like a badge of honor — as though power-cycling were some form of humiliating defeat — the majority of us can probably agree that having to restart is a pain, if only for the lost time involved. It almost seems as though the annoyance grows exponentially the more frequent they come.

According to Wikipedia, "In computing, regular expressions provide a concise and flexible means for identifying strings of text of interest, such as particular characters, words, or patterns of characters". If you even dabble in open source, shell scripts, and writing code, you are likely at least somewhat aware of regular expressions. Some people are even really good at using regular expressions, but this method can be a struggle for others. O'Reilly's Cookbook series offers over 100 "recipes" using regular expressions to solve common tasks. The question is, will this cookbook help you whip up the dish you need to serve?

Back in April we reviewed the ASRock X58 SuperComputer and found it to be a phenomenal motherboard for use with Intel Core i7 processors. While ASRock is regarded as being a budget manufacturer, this affordable Intel X58 motherboard could overclock quite far, ran well with Linux, and offered a great set of features. While that was a very nice Intel product, how are ASRock's current offerings on the AMD side? In this review we have our hands on the ASRock M3A780GXH/128M to see how well this AM3 Socket motherboard with a 780G + SB710 Chipset performs under Linux.

This article will show you how to set up openerp-server 5.0.0-3-1 + openerp-client 5.0.0-3-1 + openerp-web 5.0.1 on Ubuntu Server 9.04. Open ERP (formerly named Tiny ERP) is the leader open-source ERP/CRM system written mostly in Python and initiated in Belgium. It offers a three-tier web architecture, ease of use and flexibility.

Sugar Labs, responsible for building the low-cost device's OS, has released it online for loading onto any USB flash drive greater than 1Gb, and will allow it to be used on "any PC or netbook", it said in an announcement. Called "Sugar on a Stick v1", Sugar Labs hopes it will help spread the use of the OS in classrooms, without the need for the OLPC device. An IDC analyst said earlier this year, the OS would be one of the OLPC's more attractive aspects vendors would be interested in copying for the netbook market.

Even if you don’t want to replicate the mac, or if you think compiz is more useless than it is functional (how dare you!?), you might still be interested in replacing one of the two Gnome taskbars with a dock. Here is my dating history with the docks of Linux land.

The Sun-sponsored VirtualBox project has released a beta 3.0 version of its free, x86-oriented virtualization software. The Linux-compatible xVM VirtualBox 3.0 adds support for guest Symmetric Multiprocessing (SMP) with up to 32 virtual CPUs, as well as support for version 2.0 of the OpenGL graphics acceleration standard, among other features. Targeted at server, desktop, and embedded platforms based on x86, VirtualBox lets users run their favorite software, Sun says, while enabling developers convenience when building, testing, and running "cross-platform, multi-tier applications." It does this by enabling development and target systems to share a single physical host. Supported target "platforms" include Linux, OpenSolaris, Solaris, Windows, and Mac OS X.

Time for another Kubuntu Tutorials Day. Learn about KDE and Kubuntu development in a helpful atmosphere next Monday from 19:00UTC in the #kubuntu-devel IRC freenode channel. We have a lineup of exciting speakers on a range of topics. Read on for the timetable

Stealth has an advantage of gaining access undetected. A stealth firewall provides a way to gain access to filtering Internet traffic from a position of stealth. A bridge provides stealth because it does not use an IP Address to function but rather operates at the Layer 2 of the OSI model meaning that without an IP Address the firewall is unaccessible and hidden from all would be attackers. This course will show you how to build a stealth firewall that you can drop in anywhere on your network to protect some aspect of the network.

A Cascading Style Sheets (CSS) framework expedites and simplifies the design and development of Web pages. Moreover, a CSS framework produces more standardized results in all browsers. Here's a look at two CSS frameworks, each with a unique philosophy.

A couple of weeks ago, I wrote an article about a digital and analog circuit simulator called ksimus. One of my readers asked what the difference was between ksimus and ktechlab so I thought I'd take a look at ktechlab.
