  • Are primitive types garbage collected in Android?

    - by snctln
    I know this may be a dumb question, but my background is more in c++ and managing my own memory. I am currently cutting down every single allocation that I can from one of my games to try and reduce the frequency of garbage collection and perceived "lag", so for every variable that I create that is an Object (String and Rect for example) I am making sure that I create it before hand in my constructor and not create temporary variables in simple 10 line functions... (I hope that makes sense) Anyways I was working though it some more tonight and I realized that I may be completely wrong about my assumption on garbage collection and primitive types (int, boolean, float) are these primitive type variables that I create in a 10 line function that gets called 20 times a second adding to my problem of garbage collection? So a year ago every few seconds I would see a message in logcat like GC freed 4010 objects / 484064 bytes in 101ms Now I see that message every 15-90 seconds or so... So to rephrase my question: Are primitive types (int, float, boolean, etc) included when seeing this message?

  • Best code structure for arcade games

    - by user280454
    Hi, I've developed a few arcade games so far and have the following structure in almost all of them: I have 1 file which contains a class called kernel with the following functions: init() welcome_screen() menu_screen() help_Screen() play_game() end_screen() And another file, called Game, which basically calls all these functions and controls the flow of the game. Also, I have classes for different characters, whenever required. Is this a good code structure, or should I try having different files(classes) for different functions like welcome screen, playing, help screen, etc? As in, instead of including all the code for these things in 1 file, should I be having different classes for each one of them? The only problem I think it might cause is that I would need certain variables like score, characters, etc which are common to all of them, that's why I have all these functions in a Kernel class so that all these functions can use these variables.

I tried making them global variables, but no dice.

  • Django, ModelForms, User and UserProfile - not hashing password

    - by IvanBernat
    I'm trying to setup a User - UserProfile relationship, display the form and save the data. When submitted, the data is saved, except the password field doesn't get hashed. Additionally, how can I remove the help_text from the username and password (inherited from the User model)? Full code is below, excuse me if it's too long. Models.py USER_IS_CHOICES = ( ('u', 'Choice A'), ('p', 'Choice B'), ('n', 'Ninja'), ) class UserProfile(models.Model): user = models.ForeignKey(User, unique=True) user_is = models.CharField(max_length=1, choices=USER_IS_CHOICES) Forms.py class UserForm(forms.ModelForm): class Meta: model = User fields = ["first_name", "last_name", "username", "email", "password"] def clean_username(self): username = self.cleaned_data['username'] if not re.search(r'^\w+$', username): raise forms.ValidationError('Username can contain only alphanumeric characters') try: User.objects.get(username=username) except ObjectDoesNotExist: return username raise forms.ValidationError('Username is already taken') class UserProfileForm(forms.ModelForm): class Meta: model = UserProfile fields = ['user_is'] Views.py if request.method == 'POST': uform = UserForm(request.POST) pform = UserProfileForm(request.POST) if uform.is_valid() and pform.is_valid(): user = uform.save() profile = pform.save(commit = False) profile.user = user profile.save() return HttpResponseRedirect('/') else: uform = UserForm() pform = UserProfileForm() variables = RequestContext(request, { 'uform':uform, 'pform':pform }) return render_to_response('registration/register.html', variables)

  • CoffeeScript Class Properties Within Nested Anonymous Functions

    - by Aric
    I'm just taking a look at CoffeeScript for the first time so bare with me if this is a dumb question. I'm familiar with the hidden pattern methodology however I'm still wrapping my head around object prototypes. I'm trying to create a basic class for controlling a section on my site. The problem I'm running into is losing defined class variables within a different scope. For example, the code below works fine and creates the properties within the object perfectly. However when I jump into a jQuery callback I lose all knowledge of the class variables storing some of the jQuery objects for multiple uses. Is there a way to grab them from within the callback function? class Session initBinds: -> @loginForm.bind 'ajax:success', (data, status, xhr) -> console.log("processed") return @loginForm.bind 'ajax:before', (xhr, settings) -> console.log @loader // need access to Session.loader return return init: -> @loginForm = $("form#login-form") @loader = $("img#login-loader") this.initBinds() return

  • Liquid templates - accessing members by name

    - by egarcia
    I'm using Jekyll to create a new blog. It uses Liquid underneath. Jekyll defines certain "variables": site, content, page, post and paginator. These "variables" have several "members". For instance, post.date will return the date of a post, while post.url will return its url. My question is: can I access a variable's member using another variable as the member name? See the following example: {% if my_condition %} {% assign name = 'date' %} {% else %} {% assign name = 'url' %} {% endif %} I have a variable called name which is either 'date' or 'url'. How can I make the liquid equivalent of post[name] in ruby? The only way I've found is using a for loop to iterate over all the pairs (key-value) of post. Beware! It is quite horrible: {% for property in post %} {% if property[0] == name %} {{ property[1] }} {% endif %} {% endfor %} Argh! I hope there is a better way. Thanks.

  • emacs: force ido-mode to forget history...

    - by Stephen
    Hi, I wonder if I can keep ido from not remembering my history and only show completions for files that are in the current directory when I am searching for a file. I understand that this history feature is useful at times, but I often end up editing the incorrect file because I think I am editing file called 'abc.txt' in the current directory but in fact I am editing the file by the same name in another one that I previously visited (often happens when there is not an 'abc.txt' in the current directory, as I mistakenly assume). From reading the ido.el file I thought to set in my .emacs file (also evaluated these expressions in running emacs instance): (custom-set-variables '(ido-enable-last-directory-history nil) '(ido-record-commands nil) ) and deleted a file called .ido.last in ~/, but still it remembers some previous files I've visited before making these changes. How can I purge my previous history, and I am not entirely sure what the difference between the two variables above are but seems to have done the trick to keep ido from remembering files I visit in the future? Thanks for your help!

  • Display a "Waiting Menssage" before the POST form send

    - by DomingoSL
    I have a upload file form, when you hit Submit it send the file to my server, but it takes a while, in the mean time i need to tell the user wait in order to get the file uploaded, because he can press Submit again because there is no menssage to prevent him. So, the user fill a few fields in the form, including a file. When he Send the form it sends the variables via POST to the same page: <form action="<?php echo $_SERVER['PHP_SELF']; ?>" enctype="multipart/form-data" method="post"> A php script detect the page now have POST variables a do something. In the time between the send action and the page reload i need to display a mensage, how can i do that??? Thanks It will be nice if you now how to trigger that with colorbox. I know how to use it from a link but no from this POST action.

  • Following PHP coding of Wisdom

    - by justjoe
    i read some wisdom like this : Programmers are encouraged to be careful when using by-reference variables since they can negatively affect the readability and maintainability of the code. i make my own solution, such as give suffix such as _ref in every by-reference variables. so, if i have a variable named as $files_in_root, then i will add suffix and changes it name into $files_in_root_ref. As far my knowledge goes, this is a good solution. So, here come the question Is there any best-practice on choosing suffix for by-reference variable in PHP coder world ? Or do you have any ? In general, how do we sustain readability and maintainability on PHP project with more then 3000 line of code ? I hope PHP coder world has unwritten aggrement for first question, cause it will help spot a pattern on any source code.

  • iPhone -- initialization partly by NSKeyedUnarchiver and partly by other means

    - by William Jockusch
    I have an object myObj, which is an instance of a class MyClass. Some of its instance variables always have their initial values passed in by the calling code. Other instance variables will be initialized in one of two ways. For an instanceArray of type NSMutableArray, the possibilities are either instanceArray = [[NSMutableArray alloc]init]; or instanceArray = [someKeyedUnarchiver decodeObjectForKey: kInstanceArrayKey]; The calling code should determine which of the above will be used. Any particular design pattern I should prefer?

  • Object not disposed after calling the Dispose() function.

    - by Pavan Navali
    Hi, I have query regarding the disposing of an object. The scenario is as follows. In a Desktop Appication, developed in C#, I have a function in which a object in created like this. namespace Class 1 { variables section; .... .... Function1() { local variables; try { Object1 obj = new Object1(); .... .... if(true) { .... } else { **obj.Dispose();** } } catch() {} finally {} } } The object is not disposed when the else part is executed. The msdn link for this is http://msdn.microsoft.com/en-us/library/system.componentmodel.component.dispose(VS.90).aspx according to which the component should realase all the resources used by it. I would like to know, why the object is not disposed. Thank you. Pavan Navali.

  • PATH and CLASSPATH in Windows7 7 / Eclipse

    - by Richard Knop
    So I would like to set PATH and CLASSPATH system variables so I can use javac and java commands in the command line. I can just compile and run java programs in eclipse but I would also like to be able to run them through command line. This is where I have Java installed: C:\Program Files (x86)\Java jdk1.6.0_20 jre6 And this is where eclipse stores my Java projects: D:\java-projects HelloWorld bin HelloWorld.class src HelloWorld.java I have set up the PATH and CLASSPATH variables like this: PATH: C:\Program Files (x86)\Java\jdk1.6.0_20\bin CLASSPATH: D:\java-projects But it doesn't work. When I write: java HelloWorld Or: java HelloWorld.class I get error like this: Exception in thread “main” java.lang.NoClassDefFoundError: HelloWorld The error is longer, that's just the first line. How can I fix this? I'm mainly interested to be able to run compiled .class programs from the command line, I can do compiling in the eclipse.

  • How does a virtual machine work?

    - by Martin
    I've been looking into how programming languages work, and some of them have a so-called virtual machines. I understand that this is some form of emulation of the programming language within another programming language, and that it works like how a compiled language would be executed, with a stack. Did I get that right? With the proviso that I did, what bamboozles me is that many non-compiled languages allow variables with "liberal" type systems. In Python for example, I can write this: x = "Hello world!" x = 2**1000 Strings and big integers are completely unrelated and occupy different amounts of space in memory, so how can this code even be represented in a stack-based environment? What exactly happens here? Is x pointed to a new place on the stack and the old string data left unreferenced? Do these languages not use a stack? If not, how do they represent variables internally?

  • A couple PHP/MySQL questions...

    - by Jeff
    I am a college student taking a course in php and mysql progamming and my first question is about the "$variable" variables in the following code: <?php ob_start(); ?> <?php session_start(); if ($_SESSION['auth'] != "true") { header("Location: login.php"); exit; } $uid = $_SESSION['user']; $connection = mysql_connect("localhost", "username", "password"); mysql_select_db("username", $connection); $result = mysql_query ( "SELECT * FROM users where user_id = '$uid'", $connection); $num = mysql_numrows($result); $i=0; while ($i < $num) { $f1=mysql_result($result,$i,"firstname"); $f2=mysql_result($result,$i,"lastname"); ?> <html><body> <p> <td><center><font size = "18" face="Arial"><?php echo "Name: $f1 "; echo $f2; ?> </font></center></td> </p> </body></html> <?php $i++; } ?> <?php $result1 = mysql_query ( "SELECT * FROM phone where user_id = '$uid'", $connection); $num1 = mysql_numrows($result1); $j=0; while ($j < $num1) { $f3=mysql_result($result1,$j,"type"); $f4=mysql_result($result1,$j,"number"); ?> <html><body> <p> <br> <td><center><font size = "12" face="Arial"><?php echo "$f5: "; echo "($f3) "; echo "$f4 <br />"; ?> </font></center></td> </p> </body></html> <?php $j++; } ?> <?php $result2 = mysql_query ( "SELECT * FROM address where user_id = '$uid'", $connection); $num2 = mysql_numrows($result2); $h=0; while ($h < $num2) { $f6=mysql_result($result2,$h,"type"); $f7=mysql_result($result2,$h,"address"); $f8=mysql_result($result2,$h,"city"); $f9=mysql_result($result2,$h,"state"); $f10=mysql_result($result2,$h,"zip"); ?> <html><body> <p> <br> <td><center><font size = "12" face="Arial"><?php echo "$f10 Address: $f6, $f7, $f8 $f9"; ?></font></center></td> </p> </body></html> <?php $h++; } ?> <?php include 'navbar.php'; ob_end_flush(); ?> I just don't really understand the $variables at all. Are they user-generated or are they entities in the database? And how does the code know which $result is which? My second question is that, if this was someone else in my class's code and I wanted to modify it to make it my own and substitute my own variables, how would I go about doing that? Do the $variables need to be changed if they are not user-defined and if so, how? I apologize if these are dumb questions, but I am a beginner at this programming language. Thanks in advance for your help. -Jeff

  • Objective C Insanity -- simple assignement to a single float variable results in {{{CRAZY}}} values

    - by morgancodes
    memberA is defined in the header of ClassA. memberB is defined in the header of ClassB. ClassB is a subclass of ClassA Inside an instance of ClassB, setting memberA via simple assignment: memberA = 0.05 ...also changes memberB, but to a crazy number -- 1028443341. Additionally, assigning 0.05 to memberA results in memberA showing up in the debugger as 5.33083531e-38. Both variables are floats, neither is a pointer. I'm almost certianly making some noob mistake, but I don't have any clue what it might be. What sort of screw-up might make it so assigning a value to one variable results in crazy values appearing in two variables? I can give more details or real code, but figured I'd keep it simple to start with in case it's an obvious problem/solution.

  • RCP applicatoon activities

  • vb.net one dimensional string array manipulation difficulty

    - by Luay
    Hi, I am having some problems with manipulating a one dimensional string array in vb.net and would like your assistance please. My objective is to get 4 variables (if possible) from a file path. these variables are: myCountry, myCity, myStreet, Filename. All declared as string. The file location is also declared as string. so I have: Dim filePath As String to illustrate my problem and what I am trying to do I have the following examples: 1- C:\my\location\is\UK\Birmingham\Summer Road\this house.txt. In this example myCountry would be= UK. myCity= Birmingham. myStreet=Summer Road. Filename=this house.txt 2- C:\my Location\is\France\Lyon\that house.txt. here myCountry=France. myCity=Lyon. There is no street. Filename=that house.txt 3- C:\my Location is\Germany\the other house.txt Here myCountry=Germany. No city. No street. Filename=the other house.txt What I am trying to say is I have no idea before hand about the lenght of the string or the position of the variables I want. I also don't know if I am going to find/get a city or street name in the path. However I do now that i will get myCountry and it will be one of 5 options: UK, France, Germany, Spain, Italy. To tackle my problem, the first thing I did was Dim pathArr() As String = filePath.Split("\") to get the FileName I did: FileName = pathArr.Last To get myCountry I did: If filePath.Contains("UK") Then myCountry = "UK" ElseIf filePath.Contains("France") Then myCountry = "France" ElseIf filePath.Contains("Germany") Then myCountry = "Germany" ElseIf filePath.Contains("Spain") Then myCountry = "Spain" ElseIf filePath.Contains("Italy") Then myCountry = "Italy" End If in trying to figure out myCity and myStreet (and whether they exist in the string in the first place) I started with: Dim ind As Integer = Array.IndexOf(pathArr, myCountry) to get the index of the myCountry string. I thought I could make my way from there but I am stuck and don't know what to do next. Any help will be appreciated. Thanks

  • creating my own context processor in django

    - by dotty
    Hay, I have come to a point where i need to pass certain variables to all my views (mostly custom authentication type variables). I was told writing my own context processor was the best way to do this, but i am having some issues. My settings file looks like this TEMPLATE_CONTEXT_PROCESSORS = ( "django.contrib.auth.context_processors.auth", "django.core.context_processors.debug", "django.core.context_processors.i18n", "django.core.context_processors.media", "django.contrib.messages.context_processors.messages", "sandbox.context_processors.say_hello", ) As you can see i have a module called 'context_processors' and a function within that called 'say_hello'. This looks like def say_hello(request): return { 'say_hello':"Hello", } Am i right to assume i can now do this within my views {{ say_hello }} because it doesn't return anything.

  • Running same powershell script multiple asynchronous times with separate runspace

    - by teqnomad
    Hi, I have a powershell script which is called by a batch script which is called by Trap Receiver (which also passes environment variables) (running on windows 2008). The traps are flushed out at times in sets of 2-4 trap events, and the batch script will echo the trap details for each message to a logfile, but the powershell script on the next line of the batch script will only appear to process the first trap message (the powershell script writes to the same logfile). My interpetation is that the defaultrunspace is common to all iterations of the script running and this is why the others appear to be ignored. I've tried adding "-sta" when I invoke the powershell script using "powershell.exe -command", but this didn't help. I've researched and found a method using C# but I don't know this language, and busy enough learning powershell, so hoping to find a more direct solution especially as interleaving a "wrapper" between batch and powershell will involve passing the environment variables. http://www.codeproject.com/KB/threads/AsyncPowerShell.aspx I've hunted through stackoverflow, and again the only question of similar vein was using C#. Any suggestions welcome. Some script background: The powershell script is actually a modification of a great script found at gregorystrike website - cant post the link as I'm limited to one link but its the one for Lefthand arrays. Lots of mods so it can do multiple targets from one .ini file, taking in the environment variables, and options to run portions of the script interactively with winform. But you can see the gist of the original script. The batch script is pretty basic. The keys things are I'm trying to filter out trap noise using the :~ operator, and I tried -sta option to see if this would compartmentalise the powershell script. set debug=off set CMD_LINE_ARGS="%*" set LHIPAddress="%2" set VARBIND8="%8" shift shift shift shift shift shift shift set CHASSIS="%9" echo %DATE% %TIME% "Trap Received: %LHIPAddress% %CHASSIS% %VARBIND8%" >> C:\Logs\trap_out.txt set ACTION="%VARBIND8:~39,18%" echo %DATE% %TIME% "Action substring is %ACTION%" 2>&1 >> C:\Logs\trap_out.txt if %ACTION%=="Remote Copy Volume" ( echo Prepostlefthand_env_v2.9 >> C:\Logs\trap_out.txt c:\Windows\System32\WindowsPowerShell\v1.0\PowerShell.exe -sta -executionpolicy unrestricted -command " & 'C:\Scripts\prepostlefthand_env_v2.9.ps1' Backupsettings.ini ALL" 2>&1 >> C:\Logs\trap_out.txt ) ELSE ( echo %DATE% %TIME% Action substring is %ACTION% so exiting" 2>&1 >> C:\Logs\trap.out.txt ) exit
