• Canonical pattern reference in Actors programming model.

  - by Bubba88

  Hello! Is there a source, which I could use to learn some of the most used and popular practices regarding Actor-/Agent-oriented programming. My primary concern is about parallelism and distribution limited to the mentioned scheme - Actors, message passing. Should I begin with Erlang documentation or maybe there is any kind of book that describes the most important building blocks when programming Actor-oriented? Thank you! (Most useful examples would be in Scala or F#)

• Algorithm for sentence analysis and tokenization

  - by Andrea Nagar

  I need to analyze a document and compile statistics as to how many times each a sequence of words is used (so the analysis is not on single words but of batch of recurring words). I read that compression algorithms do something similar to what I want - creating dictionaries of blocks of text with a piece of information reporting its frequency. It should be something similar to http://www.codeproject.com/KB/recipes/Patterns.aspx Do you have anything written in C#?

• Table clusters in SQLServer

  - by Bruno Martinez

  In Oracle, a table cluster is a group of tables that share common columns and store related data in the same blocks. When tables are clustered, a single data block can contain rows from multiple tables. For example, a block can store rows from both the employees and departments tables rather than from only a single table: http://download.oracle.com/docs/cd/E11882_01/server.112/e10713/tablecls.htm#i25478 Can this be done in SQLServer?

• C# multiple asynchronous HttpRequest with one callback

  - by aepheus

  I want to make 10 asynchronous http requests at once and only process the results when all have completed and in a single callback function. I also do not want to block any threads using WaitAll (it is my understanding that WaitAll blocks until all are complete). I think I want to make a custom IAsyncResult which will handle multiple calls. Am I on the right track? Are there any good resources or examples out there that describe handling this?

• how many processors can I get in a block on cuda GPU?

  - by Vickey

  hi all, I have two questions to ask 1) If I create only one block of threads in cuda and execute the my parallel program on it then is it possible that more than one processors would be given to single block so that my program get some benefit of multiprocessor platform ? 2) can I synchronize the threads of different blocks ? if yes please give some hints. Thanks in advance since I know I'll get replies as always I get.

• Updating a TextView with a SeekBar's value (ultra-slow)

  - by Peter Bjorn

  Now look at that! I am having trouble with one of the simplest goals: updating a plain TextView with the value of a SeekBar. This is my approach: @Override public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { if (fromUser) { mInfoText.setText(mFunction.getUserFriendlyString(progress)); } } It basically works, but it kind of blocks the whole UI when I'm dragging. (Note: I tried both View.post() and Activity.runOnUiThread()). Am I overlooking something?

• tool to auto-format R code

  - by Keith

  Is there any tool (editor, script, whatever...) available that can automatically reformat R code? It does not need to be customizable but it must be able to recognize statements separated by either semicolons or newlines since this code has both. If it can put all statements on a separate line, consistently indent code blocks and consistently place braces I will be very happy.

• What's the easiest way to get the current location of an iPhone?

  - by Michiel de Mare

  I already know how to use the CLLocationManager, so I could do it the hard way, with delegates and all that. But I'd like to have a convenience method that just gets the current location, once, and blocks until it gets the result.

• generate image of basic figures with perl

I want to do all server-side; my server part is written on Perl.

• Sockets and multithreading

  - by V0idExp

  Hi to all! I have an interesting (to me) problem... There are two threads, one for capturing data from std input and sending it through socket to server, and another one which receives data from blocking socket. So, when there's no reply from server, recv() call waits indefenitely, right? But instead of blocking only its calling thread, it blocks the overall process! Why this thing occurs?

• why does Visual Studio not enforce try-catch-block implementation?

  - by Pedro

  Coming from Eclipse/Java, I noticed that in VisualStudio/C# it is not mandatory to care about Exceptions. While Eclipse forces the user to implement a try-catch-block or to add a throws declaration, this is not the case in Visual Studio. What is the reason Visual Studio doesn't inform about unhandled exceptions? Can I configure Visual Studio to force me to implement try-catch-blocks, or at least add a compiler-warning?

• Tell smarty to print block as is

  - by Juriy

  Hello guys, I need to inline some javascript code into the Smarty template files and these {ldelim} {rdelim} things are killing me. Is there a way to tell smarty to ignore the markup for a block and just output it as is? Something similar to CDATA blocks in the xml? Just in case: here is how simple javascript looks now: $(function() {ldelim} $( "#slides" ).accessNews({ldelim} speed : "{$speed}", slideBy : 1 {rdelim}); {rdelim}); creepy heh?

• How to diff just the source files?

  - by Kimvais

  I have two almost similar source code trees, but do not have access to the source code repository so I am stuck with release packages that contain also test reports, documentation, binaries etc. the diff command only support --exclude, but I would like to do something like diff -wbur --include='*.c,*.h' tree1 tree2 I know that this question is somewhat related, but does not really address my issue. Bonus points for ignoring change blocks that are completely in C comments :)

  I added a new region line to my .info file under /sites/all/themes/[theme] directory. However when I look at the Blocks page, the region is not visible, nor is it a selectable item from the dropdown menus. I've cleared the cache as well. What am I missing?

• GWT - Reusing Callback Class

  - by moorsu

  My custom callback class implements AsyncCallback (like MyAsyncCallback implements AsyncCallback) and planning use single instance of MyAsyncCallback for multiple rpc method executions. Is this approach safe?. Or should have to create new instance of MyAsyncCallback for every interaction from browser to server?. I am kind of tired of seeing so many anonymous AsyncCallback code blocks. Thanks for your input

• Rails 2.3.5 with rails_xss escaping content_for yielded content

  - by DEfusion

  Just upgraded Rails to 2.3.5 to get the lovely looking rails_xss plugin but I've noticed one big issue with it. Any content_for blocks are escaped when yielded. I've tried hacking it around by doing the either of following but they do not work: <% @content_for_foo.html_safe! -%> <%= yield raw :foo %>

• Is there an extension or mode in Emacs similar to surround.vim?

  - by Chow

  Surround.vim is a nifty vim extension that allows you to surround blocks of text with , brackets, braces, and pretty much any arbitrary "surround" character. It supports paragraph and word surround, but I frequently use it in visual mode. I'm playing around with Emacs and wondering if there's something similar; something that will let me highlight a region and then have the marked region (or rectangle) enclosed with braces, brackets or tags.

• Plugin for R# similar to CodeRush "statement highlight"

  - by KiwiBastard

  See here http://www.hanselman.com/blog/InSearchOfThePerfectMonospacedProgrammersFontInconsolata.aspx - for want of a better description - the statement block highlighting - eg in the pics on the link the "statement blocks" are grouped with a vertical line. I understand this is a feature of CodeRush - does R# have either anything similar, or a plugin to do the same?

• How do I change the curosr during a jQuery synchronous browser blocking POST?

  - by Tommy

  $.ajax({ url: "/cgi-bin/stats.exe", method: "post", async: false, data: { refresh: "a41" } }); Using ajax post synchronously - "async: false". While it blocks the browser during the active request, what is the most efficient way to change the cursor to the hourglass or display a wait .gif? Perhaps set the cursor as it enters this function then change it back in the success or complete function? Any advice is appreciated. Thank You.
