  • Arduino (processing) Library in Netbeans and control

    - by Casper Marcussen
    Hello everyone I am trying to control 4 LEDs and getting analog input from 4 contacts. The program is written in java, so to gain acces to the functions of arduino, such as AnalogRead() and setting an LED to high or low, would importing the processing library let the program use those functions? I was also wondering, if the program, will be transferred to the arduino it self, or the java program will just pull the data from the pins?

  • How to share a process?

    - by rudi
    How can I snuggle into another process? Like, share another process's name? So if my application is griddemo.exe, and I want to snug into, let's say, explorer.exe, is that possible? Just read something about CreateRemoteThread() from kernel32. Is that in the right direction? Would there be security/UAC issues?

  • Does a transaction stop all race condition problems in MySQL?

    - by nickf
    Consider this situation: Begin transaction Insert 20 records into a table with an auto_increment key Get the first insert id (let's say it's 153) Update all records in that table where id >= 153 Commit Is step 4 safe? That is, if another request comes in almost precisely at the same time, and inserts another 20 records after step 2 above, but before step 4, will there be a race condition?

  • DShow : Enumeration sequence of IEnumMoniker

    - by KenC
    Hello, This is a question about DirectShow IEnumMoniker. Out of some reason, I have to know "what kind of order" IEnumMoniker enumerates items. (I mean, it's alphabetically or...?) The following pages are documents about IEnumMoniker, however, it doesn't mention about this : http://msdn.microsoft.com/en-us/library/ms692852(v=VS.85).aspx http://msdn.microsoft.com/en-us/library/dd407292%28VS.85%29.aspx If anybody has the idea about the enumeration sequence, please let me know. Thanks a lot.

  • What's a Java alternative to Google App Engine for developing iPhone Push Notification services?

    - by bpapa
    I'm a Java programmer who is working on an iPhone application. I'd like it to use Push Notification services. I originally thought I could use Google App Engine to provide the payloads to Apple, but I see now that it won't be possible because App Engine doesn't support the low-level socket programming that is needed to communicate with Apple. Are there any alternatives to Google App Engine that let me use Java? In brief, I'm wondering if there is a free hosting platform that supports Java and Socket Programming

  • How to scrape the first paragraph from a wikipedia page?

    - by David
    Let's say I want to grab the first paragraph in this wikipedia page. How do I get the principal text between the title and contents box using XPath or DOM & PHP or something similar? Is there any php library for that? I don't want to use the api because it's a bit complex. Note: i just need that to add a widget under my pages that displays related info from Wikipedia.

  • High-Quality Text-To-Speech engine for personal use

    - by phihag
    I'm looking for a high-quality TTS engine that I can afford (let's say less than 1000$). So far, I've tried flite and festival. However, while the results are certainly understandable, technical texts are hard to follow. Commercial TTS solutions from Loquendo and Readspeaker sound way better. However, these companies don't seem to be willing to sell their product to mere mortals - I can't find a price on either's homepage. So, what are good TTS solutions for personal use?

  • Software for building a sitemap.

    - by UXdesigner
    If I had to create a content inventory for a website that doesn't have a sitemap, and I do not have access to modify the website, but the site is very large. How can I build a sitemap out of that website without having to browse it entirely ? I tried with Visio's sitemap builder, but it fails great time. Let's say for example: I Want to create a sitemap of Stackoverflow. Do you guys know a software to build it ?

  • Django: Group by?

    - by Mark
    I'm looking for something like the following: previous_invoices = Invoice.objects.filter(is_open=False).order_by('-created').group_by('user') (group_by() doesn't exist) This would find the most recently closed invoice for each user. This aggregation API seems to let you do stuff like this for counts and sums, but I don't need a count or sum or anything, I actually want the invoice objects!

  • `var = something rescue nil` behaviour

    - by JP
    In ruby you can throw a rescue at the end of an assignment to catch any errors that might come up. I have a function (below: a_function_that_may_fail) where it's convenient to let it throw an error if certain conditions aren't met. The following code works well post = {} # Other Hash stuff post['Caption'] = a_function_that_may_fail rescue nil However I'd like to have post['Caption'] not even set if the function fails. I know I can do: begin post['Caption'] = a_function_that_may_fail recsue end but that feels a little excessive - is there a simpler solution?

  • Generate SQL script to insert XML from files, using Powershell

    - by Jeff Meatball Yang
    I have a bunch of (50+) XML files in a directory that I would like to insert into a SQL server 2008 table. How can I create a SQL script from the command prompt or Powershell that will let me insert the files into a simple table with the following schema: XMLDataFiles ( xmlFileName varchar(255) , content xml ) All I need is for something to generate a script with a bunch of insert statements. Right now, I'm contemplating writing a silly little .NET console app to write the SQL script. Thanks.
