  • Finding the time to program in your spare time?

    - by Omar Kooheji
    I've got about a dozen programming projects bouncing about my head, and I'd love to contribute to some open source projects, the problem I have is that having spent the entire day staring at Visual Studio and or Eclipse (Sometimes both at the same time...) the last thing I feel like doing when I go home is program. How do you build up the motivation/time to work on your own projects after work? I'm not saying that I don't enjoy programming, it's just that I enjoy other things to and it can be hard to even do something you enjoy if you've spent all day already doing it. I think that if I worked at a chocolate factory the last thing I'd want to see when I got home was a Wonka bar.... Related: How do you keep a balance between working, training, health and family?

  • Join one row to multiple rows in another table

    - by Ghostrider
    I have a table to entities (lets call them people) and properties (one person can have an arbitrary number of properties). Ex: People Name Age -------- Jane 27 Joe 36 Jim 16 Properties Name Property ----------------- Jane Smart Jane Funny Jane Good-looking Joe Smart Joe Workaholic Jim Funny Jim Young I would like to write an efficient select that would select people based on age and return all or some of their properties. Ex: People older than 26 Name Properties Jane Smart, Funny, Good-looking Joe Smart, Workaholic It's also acceptable to return one of the properties and total property count. The query should be efficient: there are millions of rows in people table, hundreds of thousands of rows in properties table (so most people have no properties). There are hundreds of rows selected at a time. Is there any way to do it?

  • Allow swipe-to-delete in one instance of UITableViewDataSource, but not another

    - by synic
    I've got a UITableViewDataSource that I'm using for two different UITableViews. In one of the table views, I want to enable swipe-to-delete, so I've implemented tableView:commitEditingStyle:forRowAtIndexPath, and it works as expected. However, in another table, I want to disable that feature. I've got it working by making two UITableViewDataSource classes, one subclassing the other, and I only implement tableView:commitEditingStyle:forRowAtIndexPath in the subclass. I call them RecipientModel and RecipientModelEditable. I'm wondering if there's a better way.

  • Setting amount of time to pass when sending emails in a loop

    - by Obay
    Forgive me for this noob question, but is there such a setting that sets a certain amount of time (e.g. milli/seconds) that has to pass in between sending emails through a script? How is that setting called and where do I change that setting? I'll give an example: I used to have a PHP script that sends emails like so: for ($i=0; $i<count($emails); $i++) { mail($email[$i],'test','test'); } It turned out that not all emails were sent successfully because the script ran so fast that there was not enough time in between sending emails that was required by the server. Did I make sense?

  • Daylight saving time of current tz

    - by spam2
    Hi, in my c++ software I've used Boost in some parts and also for the local time. OK, now my problem is to make a check if in my machine is active or not the DST. With the follow part of code I can know only the difference from the UTC time. In my case the difference is 2 hours because is active the DST ptime tLoc = second_clock::local_time(); ptime tUTC = second_clock::universal_time(); time_duration tDiff = tUTC - tLoc; local_time_zone = tDiff.hours(); I think that the boolean funcion has_dst() can help, right? My system is Debian GNU/Linux. Thanks

  • Mercurial setup: One central repo or several?

    - by Robert S.
    My company is switching from Subversion to Mercurial. We're using .NET for our product. We have a solution with about a dozen projects that are separate modules with no dependencies on each other. We're using a central repo on a server with push/pull for our integration build. I'm trying to figure out if I should create one central repo with all the projects in it, or if I should create a separate repo for each project. One argument for separate repos is that branching the individual modules would be easier, but an argument for a single repo is easier management and workflow. I'm very new to hg and DVCS, so some guidance is greatly appreciated.

  • Need an Android Devloper with access to a Motorola Droid of Nexus One (Android 2.1)

    - by Rob Kent
    Apologies if this is the wrong place to ask this. I have an Android app on the market that has a reported problem on Droid and Nexus One (both with Android 2.1). I don't have access to the handset and cannot find anyone with one where I live. The problem I'm experiencing is partially explained at: http://stackoverflow.com/questions/2700983/problem-saving-file-on-motorola-droid-android-2-1. If you are an Android developer with either of those handsets, I'm happy to pay a reasonable fee if you'll debug the app for me. I'll send you the source. Please email me at [email protected]

  • Update multiple rows with one query?

    - by kavoir.com
    I found something that works with updating one field at here: http://www.karlrixon.co.uk/articles/sql/update-multiple-rows-with-different-values-and-a-single-sql-query/ UPDATE person SET name = CASE id WHEN 1 THEN 'Jim' WHEN 2 THEN 'Mike' WHEN 3 THEN 'Precious' END WHERE id IN (1,2,3) My question is how to update more than one field? Such as: UPDATE person SET name = CASE, sex = CASE id WHEN 1 THEN 'Jim', 'female' WHEN 2 THEN 'Mike' 'male' WHEN 3 THEN 'Precious', 'male' END WHERE id IN (1,2,3) Which doesn't work of course. Tried a few other combination and failed. Any idea? Thanks!

  • Does Android support near real time push notification

    - by j pimmel
    I recently learned about the ability of iPhone apps to receive nearly instantaneous notifications to apps. This is provided in the form of push notifications, a bespoke protocol which keeps an always on data connection to the iPhone and messages binary packets to the app, which pops up alerts incredibly quickly, between 0.5 - 5 seconds from server app send to phone app response time. This is sent as data - rather than SMS - in very very small packets charged as part of the data plan not as incoming messages. I would like to know if using Android there is either a similar facility, or whether it's possible to implement something close to this using Android APIs. To clarify I define similar as: Not an SMS message, but some data driven solution As real time as is possible Is scalable - ie: as the server part of a mobile app, I could notify thousands of app instances in seconds I appreciate the app could be pull based, HTTP request/response style, but ideally I don't want to to be polling that heavily just to check for notification .. besides which it's like drip draining the data plan.

  • iOS4.2: TouchBegan does not draw more then one circle per sensed touch

    - by Christian
    Hi all, quick question (which might be a no-brainer for most here) :) My code below should draw a circle for every time touch that is recognised but although more than ones touches are sensed only one circle will drawn up at a time. Can anyone see any obvious issues? This method sits in the XYZViewControler.m class. TouchPoint.m is the class that defines the circle. Thanks a bundle for your help and redirects. Chris - (void) touchesBegan: (NSSet *) touches withEvent: (UIEvent *)event { NSSet * allTouches = [event allTouches]; // get all events for (UITouch * touch in touches) { TouchPoint * touchPoint = [[TouchPoint alloc] initWithFrame:CGRectMake(0, 0, circleWidth, circleWidth)]; touchPoint.center = [touch locationInView:[self view]]; touchPoint.color = [UIColor redColor]; touchPoint.backgroundColor = [UIColor whiteColor]; [[self view] addSubview: touchPoint]; [touchPoint release]; CFDictionarySetValue(touchMap, touch , touchPoint); } [[self view] setNeedsDisplay]; }

  • Real-time Multiplayer Movement - Flash ActionScript 3 (AS3) - Flash Media Server

    - by Wild Phoenix
    Dear All, I am creating a simple game, where I would like more than one player to be able to connect and play. With regards to a single player game, I am more than comfortable with the coding. I cannot seem to figure out how to connect up more than one player and update their screens when the each player moves. So far I have the players connecting, but I still need to be able update the SharedObject when a player moves, then push it out to the other players. I have searched high and low for a good tutorial / source code to review. Code So Far A tutorial i found so far listened for a click as it was a mouse based movement, then this told the SHaredObject to tell the client (and the others) to update that clients movement. However all of my movement is listend and acted on in the playership class.

  • How to send html form data from one form to multiple database tables

    - by user1701556
    I am able to send html form data to database using hibernate. I am using mySQL, Hibernate, Java 1.6, Spriong 3.0. But I would like to send that same data to multiple tables in the database. My issue is that I want to use only one html form not multiple html form. I have these tables: name, address, email, login, phone_num. From this one html form I want data to go to different tables depending on what the data is. I want to do it using Hibernate so that I am not manually taking form data and inserting it in the database. Please let me know if this is possible.

  • Add entry to list and remove first one in Python

    - by wagglewax
    I have a list of about 40 entries. And I frequently want to append an item to the start of the list (with id 0) and want to delete the last entry (with id 40) of the list. how do i do this the best? like: (example with 5 entries) [0] = "herp" [1] = "derp" [2] = "blah" [3] = "what" [4] = "da..." after adding "wuggah" and deleting last it should be like: [0] = "wuggah" [1] = "herp" [2] = "derp" [3] = "blah" [4] = "what" or appending one and deleting first. And I don't want to end up manually moving them one after another all of the entries to the next id.

  • Time required for a process to complete

    - by yelkawar
    I am new to C# world. I am attempting to calculate time taken by a algorithum for the purpose of comparison. Following code measures the elapsed time from when a subroutine is called until the subroutine returns to the main program.This example is taken from "Data structures through C#" by Michael McMillan. After running this program the output is Time=0, which is incorrect. The program appears to be logically correct. Can anybody help me. Following is the code using System.Collections.Generic; using System.Collections; using System.Linq; using System.Text; namespace Chap1 { class Program { static void Main(string[] args) { int num1 = 100; int num2 = 200; Console.WriteLine("num1: " + num1); Console.WriteLine("num2: " + num2); Swap<int>(ref num1, ref num2); Console.WriteLine("num1: " + num1); Console.WriteLine("num2: " + num2); string str1 = "Sam"; string str2 = "Tom"; Console.WriteLine("String 1: " + str1); Console.WriteLine("String 2: " + str2); Swap<string>(ref str1, ref str2); Console.WriteLine("String 1: " + str1); Console.WriteLine("String 2: " + str2); Console.ReadKey(); } static void Swap<T>(ref T val1, ref T val2) { T temp; temp = val1; val1 = val2; val2 = temp; } } class Timing { TimeSpan StartTiming; TimeSpan duration; public Timing() { StartTiming = new TimeSpan(0); duration = new TimeSpan(0); } public TimeSpan startTime() { GC.Collect(); GC.WaitForPendingFinalizers(); StartTiming = Process.GetCurrentProcess().Threads[0].UserProcessorTime; return StartTiming; } public void stopTime() { duration = Process.GetCurrentProcess().Threads[0].UserProcessorTime.Subtract(StartTiming); } public TimeSpan result() { return duration; } } }

  • Wrong sessionID being used in callback, but only on one particular computer

    - by user210119
    I am writing a Python/Django web application that uses OAuth (for the TwitterAPI, not that it should matter). I am storing a session ID in my login function, and then after using OAuth to get the user's token, I try to retrieve the sessionID in my callback function. The callback function then always fails(throws an exception) because it can't find the OAuth token in the session. Through the debugger, I am able to determine that the session ID that the server is using is incorrect - it does not match the session ID that was stored in the login function. It's therefore unsurprising that the Oauth tokens were not there. The session that appears in the callback was the same one each time (until I tried deleting it - see "things I've tried below"), and it started out as an old session, with some data in it that is from a different django app running on the same server that I hadn't touched in a couple weeks. Here's the kicker: everything I described is an issue only on our production server, and only when connecting to it from my computer. Let me clarify: this only happens with my particular laptop. I can connect to the app just fine from someone else's computer. Other people cannot connect with their accounts on my computer. Furthmore, I can connect just fine to the app when it is running on my localhost using the built-in django webserver, just not to the production server. My setup: my server and local box are running= Django 1.2.0 and Python 2.6.5. My local box is running Snow Leopard and the Django webserver, the server is running Ubuntu, Apache2, and mod-wsgi. For sessions, I am using Django's default session backend (DB). Things I have tried, all to no avail: logging in with a different account, including new accounts that have never OAuthed to this app before Clearing cookies, using incognito mode, using a different web browser on my same computer. Each time, upon inspecting my cookies, the sessionID matched the sessionID in the login function and was different from the sessionID in the callback. deleting the session in the database that appears in the callback function, (the one that appeared to be old data). The callback function still fails, and the sessionID it appears to be using is now a new one using a different session backend (DB-cache, flat file, etc...) restarting the server, my computer, etc. My first question on StackOverflow, so bear with me if I didn't quite follow local conventions. I am just at a loss as to what to even look for - what are the things that could possibly be causing sessions to not work on my particular computer, and (so far!) only my particular computer?

  • (My)SQL performance: updating one field vs many unneccesary fields

    - by changokun
    i'm processing a form that has a lot of fields for a user who is editing an existing record. the user may have only changed one field, and i would typically do an update query that sets the values of all the fields, even though most of them don't change. i could do some sort of tracking to see which fields have actually changed, and only update the few that did. is there a performance difference between updating all fields in a record vs only the one that changed? are there other reasons to go with either method? the shotgun method is pretty easy...

  • from one-dimensional to two-dimensional array

    - by Thijs
    Hi again, I have this PHP one dimensional array: Array ( [Female--N] => 11 [Male--N] => 11 [Humans--N] => 11 [Adult--N] => 8 [Adolescent--N] => 8 [Reaction Time-physiology--N] => 6 [Acoustic Stimulation-methods--N] => 6 [Schizophrenia-genetics--Y] => 5 [Motion Perception--N] => 3 ) And i want a new array from this that looks like (i think this tow-dimensional..?): Array ( [Female][N] => 11 [Male][N] => 11 [Humans][N] => 11 [Adult][N] => 8 [Adolescent][N] => 8 [Reaction Time-physiology][N] => 6 [Acoustic Stimulation-methods][N] => 6 [Schizophrenia-genetics][Y] => 5 [Motion Perception][N] => 3 ) Can i use split method on key elements? Little bit harder... i also need to split on the single '_' underscore, i did this to prevent the columns getting mixed up... But the example below doesn't do the job right... $new_array = array(); foreach($MeshtagsArray as $key => $value) { $parts = explode('__', $key, 2); $parts2 = explode('_', $key, 2); $new_array[] = array( 'discriptor' => $parts[0], 'qualifier' => $parts2[1], 'major' => $parts[1], '#occurence' => $value ); So the output should be something like: [0] => Array ( [discriptor] => Female [qualifier] => [major] => N [#occurence] => 11 ........ [5] => Array ( [discriptor] => Reaction Time [qualifier] => physiology [major] => N [#occurence] => 6 Best regards, Thijs

  • Send Keyboard Events from one Form to another Form

    - by thalm
    Hello, my question is quite simple: Our C# application has one MainForm with a menu and several keyboard shortcuts associated with the menu entries. Now we need to trigger the menu entries from some child forms too. But since the MainForm is inactive when one of the child forms is active, the shortcuts do not work. Is there a simple way to propagate all keyboard events from the child form to the 'Owner' form? Or just to another form in general? Ah, and we cannot use some low level windows stuff, because we need to run the application on Mono/Linux too.
