I am using Eclipse and developed an app that has 3 tabs using Android 1.5. The program works just fine. 1st problem--whenever the app is run, it change orientations, but does not show the scroll bars, thus allowing to scroll down(or up). Is this suppose to be happening? And how is it corrected? 2nd problem--if you are on say tab2, th...
Is there a guide or documentation for designing and interfacing with iPhone4 hardware? How can I design peripheral devices that plug and communicate with iPhone4 and its iOS4, so that I create apps to use these peripherals? What accesories should I use to do that? I am already used to designing and interfacing using serial and parallel ...
I use to program with c# or c++ (at moderate level). Now i want to play with hardware, like running a small motor with a click in software, or blink a bulb with it, or even create robot like thing with it. I don't want to mess up with Assembly or other low level language. Is there any tool or programming language to play with different ...
Why are tristates favored over multiplexers to select the output from RAM? The explanation that I've heard of is that the RAM is too large for using a multiplexer but I need more details. A theory we've come up with is that using a multiplexer would necessitate a tree of OR-gates to select the output which would dramatically increase th...
I've had a desire to learn at least a tiny bit about programming hardware for quite some time now and thought I'd ask here to get some starting points. I am a reasonably accomplished programmer with Delphi and Objective-c experience but have never even listened to a device port / interupt (I dont even know the terminology) let alone pro...
I'm planning to make bluetooth hotspot system, in which when a bluetooth enabled device (such as a mobile phone) is in the area, messages can be pushed via bluetooth automatically. The device should be detected automatically if its bluetooth is turned on, and the push can be done after asking permission from the user. I'm planning to do ...
I have a little USB-powered light. I'd like to be able to turn it on and off with software. I'll be attaching it to a Linux computer. I have an Atmel ATtiny2313 from a previous project, but I'd rather do this with a simple hack than repurpose my microcontroller. Is this possible? I suspect this can't be done as the computer won't talk t...

If so, then how? I'm doing a team project for school. I thought that Java couldn't actually access hardware directly, since that would make it hard to be cross-platform. I need to know this, because after some quick Googling, I haven't found anything, and my team members(who want to do this and want to use Java) seem unsure of how to pro...

I'm reading Charles Petzold's Code and would like to build and use my own very simple computer in order to internalize better some of the concepts. I was told about CARDIAC by a friend, but it seems it isn't available anymore. So, I'm wondering if any one has suggestions on similar kits which would help to get me acquainted with similar ...
I want to control LED with C# using only USB port. I don't want to attach any other device with USB. I just want to attach LED directly to USB port pins and program it (blink etc). How can i do that? I am new to hardware programming and it will be my first program. EDIT: I can do it already (blink LED) using printer port by attaching on...
Possible Duplicate: Reliable way of generating unique hardware ID Am trying to generate an ID that will be unique to a particular computer. The ID will not be generated randomly. It will be calculation based, such that the ID generated for computer A will be fixed and unique to computer A. Everytime the program is executed on ...

Hi all, we are given some funds to renew our IT infraestructure (about 20000$). We are a small team of 5 coders, working primarily with Ubuntu / PHP-Drupal / MySQL. One of the first things we want to buy is a brand new server with lots of gigs or ram (64 at least) to allocate all the local databases, svn repos, shared directories, etc....
I have a data transformation product, which lets one select tables in a database and transform row data in the source database to a destination database. This is handled in the current product (java based workbench and engine) by processing 1000 rows at a time and doing it 10 threads parallely. This approach works fine on smaller data ...
Every time a key is pressed on a regular keyboard, a numeric 'key code' is sent to the computer, eg. 32 or 51 which represent specific keys. Unrelated to my default keyboard which I am using to type this post, I want to be able to plug in a keyboard via USB and have its key codes all shifted up by some constant C. Thus, when pressing t...
