Is there a well-known implementation, that has friendly open-source licensing (not GPL), of an ECC (error correcting code) library (e.g. Reed-Solomon) for Java?
Does anyone know of a Windows Mobile 7 device aimed at business use?
I’m looking for something with bar code scanning capability.
Psion, hand held, and honeywell only offer 6.5 at the moment.
Granted, Windows Mobile 7 just barely came out and these sorts of devices usually lag a bit behind consumer toys...but hopefully someone can help.
I've been thinking if there's a way how to speed up freeing memory in .NET. I'm creating a game in .NET (only managed code) where no significant graphics is needed but still I would like to write it properly in order to not to lose performance for nothing.
For example is it useful to assign null value to objects that are not longer needed? I see this in a few samples over Internet.
Thanks for answers!
url = "http://example.com"
new Ajax.Request(url, {
onComplete: function(transport) {
alert(transport.status);

I'd like that to return a status of 200 if the site is working, or 500 if it is not working, etc.. But that code is returning 0 all the time.
Ultimately, I want to have a setinterval function that regularly pings a website for uptime status.
I have been struggling in fixing this code, wonder what is wrong at all...

I've a daunting task of getting familiair and possibly re-architecting large pieces of old source code.
I was hoping there would be a nice tool to convert php (in my case), but let's make it more general: any language to PDF, for offline browsing on a Kindle or Ipad
Would be ideal if it would create indexes / hyperlinks automatically. So function calls can be easily browsed into
Hi,
Just wondering, would the following code arrangement cause any issues when calling mysql_connect, i.e.:
public function connect() {
mysql_connect($this->host,
$this->username,
$this->password)
or die("Could not connect. " . mysql_error());
or does it need to be all on one line, i.e.:
mysql_connect($this->host,$this->username,$this->password) or die("Could not connect. " . mysql_error());
Thanks.
I am trying to create a landscape and portrait mode only for tablets. For portrait mode I added the files under layout-xlarge and for landscape in tablets I added files under layout-xlarge-land, but just to test if its working I tried switching the background color under landscape to green, but it didnt seem to work. Is there anything else I need to alter for code to recognize landscape mode for tablets?

I know i can simulate a memory warning on the simulator by selecting 'Simulate Memory Warning' from the drop down menu of the iPhone Simulator. I can even make a hot key for that.
But this is not what I'd like to achieve. I'd like to do that from the code by simply, lets say doing it every 5 seconds. Is that possible?
I'm a bit perplexed by some code I'm currently writing. I am trying to preform a specific gradient descent (main loop included below) and depending on the initial conditions I will alternatively get good looking results (perhaps 20% of the time) or everything becomes NaN (the other 80% of the time). However it seems to me that none of the operations in my code could produce NaN's when given honest numbers!
My main loop is:
// calculate errors
delta = m1 + m2 - M;
eta = f1 + f2 - F;
for (int i = 0; i < numChildren; i++) {
epsilon[i] = p[i]*m1+(1-p[i])*m2+q[i]*f1+(1-q[i])*f2-C[i];
}
// use errors in gradient descent
// set aside differences for the p's and q's
float mDiff = m1 - m2;
float fDiff = f1 - f2;
// first update m's and f's
m1 -= rate*delta;
m2 -= rate*delta;
f1 -= rate*eta;
f2 -= rate*eta;
for (int i = 0; i < numChildren; i++) {
m1 -= rate*epsilon[i]*p[i];
m2 -= rate*epsilon[i]*(1-p[i]);
f1 -= rate*epsilon[i]*q[i];
f2 -= rate*epsilon[i]*(1-q[i]);
}
// now update the p's and q's
for (int i = 0; i < numChildren; i++) {
p[i] -= rate*epsilon[i]*mDiff;
q[i] -= rate*epsilon[i]*fDiff;
}
This behavior can be seen when we have
rate = 0.01;
M = 30;
F = 30;
C = {15, 25, 35, 45};
with the p[i] and q[i] chosen randomly uniformly between 0 and 1, m1 and m2 chosen randomly uniformly to add to M, and f1 and f2 chosen randomly uniformly to add up to F.
Does anyone see anything that could create these NaN's?
Hi, what does the 0x80 code mean when referring to the keyboard controls in C++ Windows environment?
For example,
if(GetKeyState('K') & 0x80) {
//do something
}
Thanks everyone!
Hi, I am wondering what this line of code mean?
b = (gen_rand_uniform()>0.5)?1:0;
The gren_rand_uniform() is a function to generate random 0 and 1 numbers. However I don't get the meaning for >0.5 and 1:0.
I know this is supposed to be a basic question, please bear with me.
Thanks!
I am new to iPhone development. I just registered with Apple for the iPhone Developer Program. When I try to build, I am receiving an error:
Code Sign error: a valid provisioning profile matching the application’s identifier could not be found
I'm not sure what is wrong. I tried browsing the Internet but I get confused. Can anyone help me with what I should do?
I'm looking for code coverage solution which works with silverligt. It must also work with msbuild because we run all the other unit tests automatically in the build server.
Integration with Visual Studio and/or resharper is a plus and I have nothing against easy setup or a pointer to a tutorial. I don't usually modify the build files and unfortunately I don't have time to learn msbuild at the moment.
Hello everyone,
I am using MacBook Pro Mac OS 10.5 with related version of XCode. I am new to this development environment. I am developing C++ console/terminal applications (File-New project, then from the list on the left "Command line utility", and on the right "C++ tool".).

What is the correct way of knowing operating system language (locale) from java code?

Please help.
Is there any way to bulk-export Microsoft Access code to files? I see I can export one file at a time, but there are hundreds and I'll be here all day. It there no "Export All" or multi-select export anywhere?

I know there are tools like Salamander that can compile a .NET WinForms apps to fully native code with no need for the CLR/.NET Framework to be on a machine. Is this possible for WPF apps as well?
