Webaroo rocks…..

I tried this software developed by Webaroo Inc which allows you to download web pages (so called web packs ) and view them offline ,now this web packs are updated as the web pages are updated .For this you need their client installed.this client right now is available only for windows based platform.Webaroo is also available for j2me devies as well as u3 devices.

Another feature that i liked is that you can download this web packs on usb devices and carry it wherever you go this are updated as soon as you connect to internet .

Now readers must be thinking why am i posting abt webaroo on a linux blog,reason is i have friend who works for webaroo and said linux installer may be available in future releases ,so just letting the cat out of the bag.

Rgarding web packs availabe the biggest one is the wikipedia one which is abt 4.7 gb so quite big..But how abt having entire wikipedia offline or burning it on a cd and letting school children have it ..No need to buy brittanica or Encarta ..

Also once you have downloaded the web packs you can add websites to it if you want it to be available offline ,(I havent tried this)..

The J2me version of webaroo has a problem ..it des not update the pacakges downloaded ..so needs a fix and the web packs available in this case are limited(they have been adapted for the mobile version so no worry over the size of web packs over there)

Check out all the web packs available on this webaroo.

As far as rating it ill give 3/5 ….

let meknow whether you liked it or not..

Now a Linux university for developers

Novell has started a program for developers helping them deploy new technologies in linux for example mono and real basic .

The program moto is ”

Linux University for Developers is a collaborative initiative by developers, designed for developers to share their knowledge on how easy it is to create software on Linux. ”

Here engineers/developers around the world can write article on cocepts or technologies of their choice and let others learn from it .Primarily articles are based on opensource ,so one can find articles on mono,ruby ,gtk+ and gnome .I tried the gnome article and its good.

All this courses have be written in flash so it works in any web browser provided you have the plugins installed.

You can run the courses online or download it from

forgeftp.novell.com/lu4d

Budding developers Check it out.

openSUSE Community

openSUSE has started a wiki where all articles regarding openSUSE can be written,it needs people to write articles write now ,About 30 to 40 articles are currently available right now but it will start expanding as people start writing more .Its a great way to have it since it helps newbies to begin with ,and also they find answers to all their queries on one single domain.So hop on everyone and start contributing.

Ktechlab needs your help!

Hello everyone,

I have been using this electronic application called ktechlab for a while,i found that it is a pretty good application for electronic ppl,ppl who design circuits,ppl who write microcode and for ppl who want to build PIC.

KTechlab is a young open source electronic design automation software. It supports real-time electronics simulation and PIC microcontroller debuggin.

KTechLab includes a whole programming language called MicroBASIC and associated compiler for programming PICs. It can compile the flow diagrams into MicroBASIC and from there into an assembly language compatible with MPASM as used by the manufacturer of PICs. The assembly language can be compiled into a machine code suitable and compiler for feeding into PICs.


KTechLab uses the KMDI interface familiar to users of Kate or KDevelop. (You can change this layout but this seems to cause problems and KMDI is the most usable.) Diagrams and code are displayed as tabs and each diagram is saved as an XML file using a custom language and a file extention of .flowcode or .circuit. You can group together diagrams and code files into projects which makes a file with a .ktechlab extention that points to the other files but I wonder if it would be more intuitive to just have one file for all your diagrams and code.

Around the edge of the canvas you’ll find electrical components which can be dragged onto circuit diagrams and flow parts for flow chart diagrams. I usually find it best to keep this left hand sidebar open all the time when working, you can do this by clicking on the “Overlap” button (square icon) at the top of the sidebar. On the right hand side is an Item sidebar which gives information and lets you set properties of the currently selected item in the diagram. There is also a context help sidebar giving a helpful description of the currently selected item in the diagram. Many Free Software applications are criticised for their lack of documentation so it is refreshing to find one which goes out of its way to provide extra documentation.

Having worked on Umbrello which also draws diagrams I find myself jealous at the intelligent way the connections joining diagram items route themselves. You can also do manual connection routing if you are not happy with the automatic routing. Diagrams can not currently be resized or zoomed, maybe this will be added in future versions (although it is actually quite difficult to get QCanvas drawings to be resizable on the top and left hand sides).

Using KTechLab

A flowchart is probably the best place to start. In the top left or the diagram is a picture of the PIC chip, this show its initial settings, it is not part of the flowchart itself. You can change these initial settings by clicking on each connects of the PIC to turn it on or off, clicking and dragging left or right will set it to be an input or an output. Flowcharts need a start and end which you can drag in from the flow part sidebar. You can then drag in any of the other flowchar actions and connect them together. Dragging in a subroutine adds a large diagram item into which you can put other items.

 

Ktechlab_2Ktechlab_1

Once you have your flowchart you can convert it into microbasic, assembly code or directly into machine (hex) code by using the buttons on the right hand side of the toolbar (or from the Tools menu).

Now we can make a new circuit diagram. The Components sidebar contains assorted electrical items that can be dragged onto the diagram. At the very bottom is a PIC 18 Pin item. If you add this to a diagram it can be associated with the flowchart you just made (or one of its code representations). Click on the PIC and point it towards the file with your flowchart by editing the filename box in the toolbar. If you now run the PIC by clicking the play button below it the circuit should run according to your flow diagram, you can see the output in the gpsim box at the bottom of the diagram.

But alas Looks like the Developer is no longer working on the said application and no new releases have been issued so i believe that this application wont be going any further ,so it needs developers,geeks to help it start again.Pls guys dont let this appln go down the drain ,It needs Your help.

The sourceforge repository retuns nothing so if you want the packages you will have to download it from rpm.pbone.net.”A word of caution for opensuse users you will have to satisfy many dependencys before you can have it working” ,but it works i have it working on my opensuse 10.2 machine.

PLS HELP KTECHLAB.

Does anyone Know a good Electronic App in Linux ?

Hey ,does anyone know a good electronic app in linux that can help me design circuits as well as test them on simulator,Something that is similar to ktechlab.But since ktechlab is defunct ,i would like to use a new one.If anyone knows a good app pls let me know.
