Submission + - KDE SC 4.5 RC1- The (well) hidden features (

An anonymous reader writes: This is the third in a series of posts about the pre-releases of KDE SC 4.5. This one is about the first release candidate. In the previous posts about beta 1 and beta 2 I went over the new features in 4.5 – few as they are. I also pointed out that one of the focuses of this release is stability. Obviously RC 1 adds no new features, so what is there to talk about? Well, there’s more stability – since beta 2 was released, 1233 bugs have been reported and 1165 have been closed – pretty impressive.

Submission + - Google bringing HTML5 to Gmail ( 1

angry tapir writes: "In keeping with Google's enthusiasm for the emerging HTML5 standard, many upcoming features of the company's Gmail Web-based e-mail service will be rendered in HTML5. One feature that the Gmail design team is now working on is the ability to drag files from the desktop into the browser. Gmail will also make use of HTML5's database standards. Currently the e-mail service uses Google Gears to store mail for offline reading, but over time that will migrate to the HTML5 standards."

Submission + - How to find Wifi interference? 4

Nicros writes: So I am experiencing a somewhat bizarre thing. Almost every evening, between 8:30 and 10- my wifi seems to just die. This, in itself, could be explained by a crappy wifi source or some hardware failure, except that I know both of my neighbors are experiencing the SAME loss of signal at the same time! While the wifi is down, the lan is just fine, and any plugged into cat5 can access the internet just fine. It is only the wifi portion of our routers that we cant access.

So a couple things come to mind- is it possible that some other neighbor arrives at home and is the type that turns on their router from 8:30-10? And that there is something that is hosing our wifi? Or what other possible causes may there be?

I have tried looking around for software to help identify the source of interference, but either they are ridiculously expensive for a home user or my card (intel link 1000 BGN) isnt supported (like by netstumbler).

Anyone have any suggestions on how I can track this down?


Submission + - A Look At NASA's Unmanned Aircraft (

krou writes: The BBC takes a look at NASA's new unmanned aircraft, and spoke to Doctor Paul Newman, one of the project leaders behind NASA's usage of three Global Hawk drones acquired from the US military to conduct environmental research. The Global Hawk recently undertook its first science flight over the Pacific, the first of five missions to study atmospheric science over the Pacific and Arctic oceans. It carries '11 instruments to sample the chemical composition of the troposphere and stratosphere [and is able to] profile the dynamics and meteorology of both layers and observe the distribution of clouds and aerosol particles'. Paul Newman said that 'The Global Hawk is a revolutionary aircraft for science because of its enormous range and endurance. No other science platform provides the range and time to sample rapidly evolving atmospheric phenomena. This mission is our first opportunity to demonstrate the unique capabilities of this plane, while gathering atmospheric data in a region that is poorly sampled.'

Submission + - Lightworks video editor to turn open source

Art3x writes: EditShare will release its video editor as open source this summer. Lightworks handles high-definition media, DPX, and RED, shares projects with Final Cut Pro and Avid, and was recently used by Academy-award-winning editor Thelma Schoonmaker on Shutter Island. Introduced in in 1989 and bought by EditShare last year, it 'has come from over one million hours of software development,' says EditShare's James Richings. But he says releasing the source will 'generate concepts and capabilities never seen before. I expect that the Lightworks Open Source initiative will transform not only the technology, but also the opinions on what a professional editing tool can achieve.'

Submission + - Advice for Restoring Training Systems after Class

An anonymous reader writes: I have been a long-time lurker but now need the advice of the "Ask Slashdot" community:

The company I work for offers training for CAD and Multimedia applications (AutoCAD, Autodesk Inventor [similar to SolidWorks], 3D Studio MAX, etc.). Up to this point we have used ghosting to restore the workstations after a training course. The problem with restoring an image is that it a) requires some administrative work by our training coordinator b) isn't very efficient because the entire image is restored even though only a very small portion of apps/data is different between the current state and the image.

My initial thought was to implement virtualization since this would allow us to create "snapshots" which could easily be restored / deleted. However, because of the type of software we train on, having native or near-native graphics performance is essential and all of the desktop virtualization products are lacking in this area (personally tested Virtual PC, VMWare Workstation and Virtual Box). Within the desktop virtualization market, the best option I found was Parallels Workstation Extreme but it requires significant investment in certified hardware. Also, we often train at our customers' site using notebooks so virtualizing an application via a DataCenter is not an option.

Therefore, at this point, it appears as if neither ghosting or virtualization are viable options. As I've thought about it, I'm thinking that the best course of action would be to implement a product that allows you to create an "Undo Disk" on the physical hardware. In this environment, you would run the O/S on the physical hardware but all modifications would be stored within a separate file / partition which if deleted, would restore the machine to its "base" state. Overall, this would accomplish my objective of full performance with quick restores (since only the "delta" difference needs to be removed; unlike in ghosting) and could even by done by the trainer at the start of the class. I haven't found a product in my searching that does this. I don't think that Windows Restore Points are the answer because it isn't a true snapshot since some settings are not captured and are thus retained when going back in time.

  It is my responsibility at work to implement a more efficient means of dealing with our training systems and would appreciate any guidance.

Submission + - Boeing: We zapped a UAV with a laser (

mytrip writes: "Boeing is seeing a glimmer of progress in its work toward fielding laser weapons.

The defense industry giant on Monday said tests of its Laser Avenger system in December marked "the first time a combat vehicle has used a laser to shoot down a UAV," or unmanned aerial vehicle. In the testing, the Humvee-mounted Laser Avenger located and tracked three small UAVs in flight over the White Sands Missile Range in New Mexico and knocked one of the drone aircraft out of the sky.

Boeing didn't go into much detail about the shoot-down. In response to a query by CNET News, it did say this much about the strike by the the kilowatt-class laser: "A hole was burned in a critical flight control element of the UAV, rendering the aircraft unflyable.""


Submission + - Russia to Create "National OS" Rival to Wi ( 1

Glyn Moody writes: "Russia's President Medvedev is being asked to fund the creation of a "National OS", based on GNU/Linux. The idea is to reduce Russia's dependency on Western software — both proprietary and free — by developing an operating system that is completely under its control. Strangely, the head of Microsoft Russia is against the idea."

Use C/C++ libraries from within KBasic
KBasic supports calling functions of C/C++ library files (*.DLL, *.SO and *.DYLIB) enabling you to mix C/C++ and BASIC code.

Database and SQL

Supported databases on all platforms are

KBasic uses SQLite as embedded database engine, which creates database files locally on your machine without the need of a database server.

The SQL binding for controls helps you to easily create data-aware forms.

You may store date, time, text, numbers, images, movies and sounds or any binary data within a database.

* Some features are not available yet.


If you deploy your application, you might consider making it available for different languages. KBasic helps you with this task by adding support for translations. For each form you may create a translated form and for each text, you may provide a translated version.

Unicode and String
KBasic gives you the possibility to support non-latin languages, e.g. Arabic or Chinese characters. The String data type comes with a built-in Unicode support in KBasic.

KBasic enables you to directly use the math functions commonly used in BASIC applications. It declares a set of functions to compute common mathematical operations and transformations. Additional, you may directly use the C library math functions commonly used in C/C++ applications.

Date and time

Support for dealing with date and time is built-in as well.

Rich text format (RTF)
KBasic give you the control for dealing with RTF. You may use an advanced WYSIWYG viewer/editor control supporting rich text formatting using HTML-style tags. It is optimized to handle large documents and to respond quickly to user input. It can display a large HTML subset, including tables and images and custom syntax highlighting.

Submission + - Qt goes LGPL

Balinares writes: Nokia announces today that the cross-platform Qt toolkit, which is the foundation of many open sources projects such as the KDE desktop environment, will be available under the LGPL license as of the next version, Qt 4.5. The former GPL/commercial dual licensing of Qt had been a source of controversy in the open source community for many years.

Submission + - Qt becomes LGPL!

Aequo writes: Qt, the highly polished, well documented, modern GUI toolkit owned by Nokia will be available under the LGPL starting with version 4.5! It was previously only mainly available under the GPL and a commercial license. Selling licenses was an important part of Qt under Trolltech as it was the company's main source of income, but Trolltech is a fruit-fly compared to Nokia, who want to encourage and stimulate the use of Qt Everywhere [PDF]. This is fantastic news for all commercial developers looking to create cross-platform applications without the need to buy a $4950 multi-platform license per developer.
