• jquery value of textarea

  - by Elliott

  Hi, I have the code below, which sends the value of the textarea and either gets a fail or Successful response, for now I just check if it says "hello". function postdata() { $.ajax({ type: "POST", dataType: "text", url: "makepost.php", data: "post_text=" + $("#post_text").val(), cache: false, success: function(reply_text) { if (reply_text.indexOf("Successful") >= 0) { alert("Post Made"); } else { alert(reply_text); } } }); } <textarea rows="3" cols="25" id="post_text" ></textarea><br /> <input type="submit" id="post_bttn" value="Post" onclick="postdata(); return false;"> I have also tested just echo'ing out the value of the textarea, and all the time it is jus blank.

• JSON in an AJAX request

  - by Josh K

  I have a PHP API I'm working with that outputs everything as JSON. I need to call one of the API methods and parse it out using an AJAX request. I am using jQuery (though it shouldn't matter). When I make the request it errors out with a "parsererror" as the textStatus and a "Syntax Error: invalid label" when I make the request. Simplified code: $.ajax ({ type: "POST", url: "http://mydomain.com/api/get/userlist/"+mid, dataType: "json", dataFilter: function(data, type) { /* Here we assume and pray */ users = eval(data); alert(users[1].id); }, success: function(data, textStatus, XMLHttpRequest) { alert(data.length); // Should be an array, yet is undefined. }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); }, complete: function(XMLHttpRequest, textStatus) { alert("Done"); } });

• LRU caches in C

  - by lazyconfabulator

  I need to cache a large (but variable) number of smallish (1 kilobyte to 10 megabytes) files in memory, for a C application (in a *nix environment). Since I don't want to eat all my memory, I'd like to set hard memory limit (say, 64 megabytes) and push files into a hash table with the file name as the key and dispose of the entries with the least use. What I believe I need is an LRU cache. Really, I'd rather not roll my own so if someone knows where I can find a workable library, please point the way? Failing that, can someone provide a simple example of an LRU cache in C? Related posts indicated that a hash table with a doubly-linked list, but I'm not even clear on how a doubly-linked list keeps LRU. Side note: I realize this is almost exactly the function of memcache, but it's not an option for me. I also took a look at the source hoping to enlighten myself on LRU caching, with no success.

• Can't append space at end of UITextView

  - by Sam V

  I have a UITextView in which I want the initial value to be "@username " (notice the space after the username). This way the user can start typing right away without having to tap space. So I do: textView.text = [NSString stringWithFormat:@"@%@ ", username]; But it seems like it's impossible to have the UITextView text property ending with a space (it always gets stripped out). Am I correct? Is there any workaround for this? I tried using the \s char and no success.

• Online product demo environment for Windows applications

  - by Stefanos Tses

  I'm looking for a way to allow potential customers to try my application before they buy it. The product is a windows forms application that requires an SQL Server database to operate. Although I have a functional demo that the customer can install on their network, I want to make it easier for them by have them "play" with it at my environment. I remember Microsoft had (has?) something similar. I was testing Visual Studio a few years ago in a virtual environment where I was connecting to a server at Microsoft. Any suggestions? Thanks.

• Multiple levels of 'collection.defaultdict' in Python

  - by Morlock

  Thanks to some great folks on SO, I discovered the possibilities offered by collections.defaultdict, notably in readability and speed. I have put them to use with success. Now I would like to implement three levels of dictionaries, the two top ones being defaultdict and the lowest one being int. I don't find the appropriate way to do this. Here is my attempt: from collections import defaultdict d = defaultdict(defaultdict) a = [("key1", {"a1":22, "a2":33}), ("key2", {"a1":32, "a2":55}), ("key3", {"a1":43, "a2":44})] for i in a: d[i[0]] = i[1] Now this works, but the following, which is the desired behavior, doesn't: d["key4"]["a1"] + 1 I suspect that I should have declared somewhere that the second level defaultdict is of type int, but I didn't find where or how to do so. The reason I am using defaultdict in the first place is to avoid having to initialize the dictionary for each new key. Any more elegant suggestion? Thanks pythoneers!

• Is it possible to write a Skype client?

  - by JCasso

  Is there any libraries for this? I will put this on a server and it will be a windows service. And Skype will not be installed on server. So Skype API will not mean anything I guess. Edit: I am sorry for not being clear. Here is what i need: I just need a Skype client which will act like a small bot. A person who uses Skype will ask it something like: print totalCreditsLoadedToday And it will answer: 567867867 credits. I need to write a windows service which will accept text messages from Skype and will send responses as text message (a very simple Skype client). I don't need voip support but Skype is a, errr customer requirement lets say. (And yes I suggested Google Talk but not accepted) But i need to achieve this without installing Skype to the server.

• Whats wrong with this task queue setup?

  - by Peter Farmer

  I've setup this task queue implementation on a site I host for a customer, it has a cron job which runs each morning at 2am "/admin/tasks/queue", this queues up emails to be sent out, "/admin/tasks/email", and uses cursors so as to do the queuing in small chunks. For some reason last night /admin/tasks/queue kept getting run by this code and so sent out my whole quota of emails :/. Have I done something wrong with this code? class QueueUpEmail(webapp.RequestHandler): def post(self): subscribers = Subscriber.all() subscribers.filter("verified =", True) last_cursor = memcache.get('daily_email_cursor') if last_cursor: subscribers.with_cursor(last_cursor) subs = subscribers.fetch(10) logging.debug("POST - subs count = %i" % len(subs)) if len(subs) < 10: logging.debug("POST - Less than 10 subscribers in subs") # Subscribers left is less than 10, don't reschedule the task for sub in subs: task = taskqueue.Task(url='/admin/tasks/email', params={'email': sub.emailaddress, 'day': sub.day_no}) task.add("email") memcache.delete('daily_email_cursor') else: logging.debug("POST - Greater than 10 subscibers left in subs - reschedule") # Subscribers is 10 or greater, reschedule for sub in subs: task = taskqueue.Task(url='/admin/tasks/email', params={'email': sub.emailaddress, 'day': sub.day_no}) task.add("email") cursor = subscribers.cursor() memcache.set('daily_email_cursor', cursor) task = taskqueue.Task(url="/admin/tasks/queue", params={}) task.add("queueup")

• SwingWorker in Java (beginner question)

  I am relatively new to multi-threading and want to execute a background task using a Swingworker thread - the method that is called does not actually return anything but I would like to be notified when it has completed. The code I have so far doesn't appear to be working: private void crawl(ActionEvent evt) { try { SwingWorker<Void, Void> crawler = new SwingWorker<Void, Void>() { @Override protected Void doInBackground() throws Exception { Discoverer discover = new Discoverer(); discover.crawl(); return null; } @Override protected void done() { JOptionPane.showMessageDialog(jfThis, "Finished Crawling", "Success", JOptionPane.INFORMATION_MESSAGE); } }; crawler.execute(); } catch (Exception ex) { JOptionPane.showMessageDialog(this, ex.getMessage(), "Exception", JOptionPane.ERROR_MESSAGE); } } Any feedback/advice would be greatly appreciated as multi-threading is a big area of programming that I am weak in.

• How much should I charge for Rails programming?

  - by Oskar Gantt

  I have been asked to quote an hourly rate for freelance programming for a Rails project. Although it would be my first paid project on Rails, I know the technology well from personal projects and have a decade of professional programming experience. This would be my first freelance project ever, so I have no idea how to find out what the going rate for my services should be. Obviously, if I quote a rate that is too high, they may choose someone else - too low and I may feel cheated later on. Any suggestions? Update: I am in NYC and the project is scheduled for 6 months to a year (but this seems unrealistic - I think it will be a multi-year project). I would develop on site (at a corporate location) with one other developer and the project would consist of about 200 custom-built pages initially. 10 hour days with weekends and additional overtime as required. The customer has given no information about how much they will pay - "a competitive rate" - they want me to start the discussion.

• Are Sphinx & thinking_sphinx really stable? Not indexing Columns

  - by seb

  I'm encountering strange behaviour from thinking_sphinx/sphinx. My define_index block is about 100 lines, so quite a lot of columns i'm indexing. For full-text searching I only need about 10 attributes, for sorting and filtering I have another approximately 50 columns, mostly floats and integers. By filtering I mean using the "with" or "without" options. Searching does not really work consistently. All of a sudden, one attribute fails to filter. Or if I add a new one, it does not work. Only after a lot of tinkering it suddenly starts working. I cannot really reproduce it. Steps I that sometimes lead me to success where: rm -rf db/sphinx change the attribute definition e.g. has some_attribute = has some_attribute, :sortable = true or = has some_attribute, :sortable = true, :as = "some_attribute" restarting the server assigning a new :as name = has some_attribute, :as = "some_attribute_new" (yes, I did rake ts:rebuild or rake ts:in after every step) Does anybody else encounter similar problems?

• Using trace and dbg in Erlang

  - by Gordon Guthrie

  I am trying to start using erlang:trace/3 and the dbg module to trace the behaviour of a live production system without taking the server down. The documentation is opaque (to put it mildly) and there don't appear to be any useful tutorials online. What I spent all day trying to do was capture what was happening in a particular function by trying to apply a trace to module:function using dbg:c and dbg:p but with no success at all... Does anyone have a succinct explanation of how to use trace in a live Erlang system?

• Mapping class properties to generic columns in table .NET

  - by Tony_Henrich

  I have have a SQL Server table which has generic names like Text1, Text2.. etc. The table was designed like this because the same structure is used for different projects. I have a class in .NET which has properties. Say a Customer class has a property called FirstName. How can I do the mapping from FirstName to Text1 just once (central place) in the application so that I don't have to remember and hard code the mappings all over the app when I create the different DAL methods? For example, I want the app to know when I want to update, insert a FirstName, the DAL automatically uses Text1. Basically I don't have to remember which property goes to which column. The idea is so the developers do not map the properlies/columns in a wrong way. It's always consistent. Note: Database inserts, updates and deletes are allowed through stored procedures only.
