• Images or files in GNU Smalltalk?

  - by Marc

  Hi, I'm new to Smalltalk. I think I understand the basics of the language and now want to start with GNU Smalltalk (as it's free and has bindings for GTK). As I'm coming from the PHP and Java-Corner, I'm not familiar with the concept of the Smalltalk images. And I even read now, that you don't need to use images in GNU Smalltalk. Now I'm confused ;-) So is it possible to work with files and to include the classes I need with the PackageLoader class? I would be happy when I could use my favourite texteditor (vim) for coding instead of an IDE, too ;-) Please enlight me :-)

  - by Diego

  Hey guys, i'm really trying to understand regular expressions while scraping a site, i've been using it in my code enough to pull the following, but am stuck here. I need to quickly grab this: http://www.example.com/online/store/TitleDetail?detail&sku=123456789 from this: ('<a href="javascript:if(handleDoubleClick(this.id)){window.location=\'http://www.example.com/online/store/TitleDetail?detail&sku=123456789\';}" id="getTitleDetails_123456789">\r\n\t\t\t \tcheck store inventory\r\n\t\t\t </a>', 1) This is where I got confused. any ideas?

• Can't write text into textbox in ASP.NET web app

  - by dotnetdev

  Hi, I have an ASP.NET web application. In the codebehind for the .ascx page (which I embed as below), I attempt to write a string to a textbox in a method like this: Code for embedding control: Control ctrl = Page.LoadControl("/RackRecable.ascx"); PlaceHolder1.Controls.Add(ctrl); Method to make string for inserting into textbox: string AppendDetails() { StringBuilder sb = new StringBuilder(); sb.Append("msg" + " " + textbox1.Text etc etc ); return sb.ToString(); } Called as (in codebehind event handler for button click): this.TextBox4.Text = AppendDetails(); I call it by using ATextBox.Text = AppendDetails (in the button click event handler). The textbox TextBox4 is in the designer file so I am confused why the text does not get written into this textbox (it is readonly and enabled). When stepping through, the textbox4 control will successfully show the text I want it to display in quick watch but not in the actual page, it won't. Any ideas? Thanks

• How are Flash library symbols constructed? Why are width/height already available in constructor?

  - by Triynko

  Suppose I draw a square on the stage, convert it to a symbol, export it for ActionScript with a classname of "MySquare" (and of course a base class of MovieClip). How is it that in the MySquare constructor, the width and height of this MovieClip are already available? In fact, any named instances in the clip are also available. I'm confused about how the Flash player seems to be able to pre-construct my movie clip by populating its properties and child clips before my constructor for the class ever runs. I thought that it would have to first construct the clip, calling my constructor code, and then construct and add any children, but obviously the player is doing something special for clips designed in the Flash authoring environment.

• What is the "task" in twitter Storm parallelism

  - by John Wang

  I'm trying to learn twitter storm by following the great article "Understanding the parallelism of a Storm topology" However I'm a bit confused by the concept of "task". Is a task an running instance of the component(spout or bolt) ? A executor having multiple tasks actually is saying the same component is executed for multiple times by the executor, am I correct ? Moreover in a general parallelism sense, Storm will spawn a dedicated thread(executor) for a spout or bolt, but what is contributed to the parallelism by an executor(thread) having multiple tasks ? I think having multiple tasks in a thread, since a thread executes sequentially, only make the thread a kind of "cached" resource, which avoids spawning new thread for next task run. Am I correct? I may clear those confusion by myself after taking more time to investigate, but you know, we both love stackoverflow ;-) Thanks in advance.

• Javascriptlibrary more efficient than Rickshaw for realtime visualizations

  - by dan kutz

  I want to visualize data as time-series graphs on mobile devices(tablets) and therefore stumbled upon rickshaw, which is based on D3. First I must say I was a little bit confused when I realized that realtime in web design is defined totally different to realtime in engineering which has fixed(and often very short) timeframes. Anyway my aim is to visualize the data as fast as possible, and on older tablets visualization with rickshaw is quite slow. Can anybody recommend another library, which may be more efficient in rendering? Or is there no way out and I have to go native? regards Dan.

• W3C Web Content Accessibility Guidelines 1.0, which technology could I use?

  - by vtortola

  Hi, I've a project where one of the requirements is fullfil the "W3C Web Content Accessibility Guidelines 1.0 (WCAG 1.0)". I'm now considering wich technology could I use to acomplish it, but I'm a little bit confused. Silverlight would be the easiest way, but I cannot find conclusive information about if silverlight is or isn't compilant. I've seen controls pack done in javascript that looks very nice, like DHTMLX, but again the same problem, I don't know for sure. Besides, I've always read that a website should work wihthout javascript, and use it just for improve the user experience. Thanks.

• Drawing Sprites for iOS games on iPad

  - by TheGamingArt

  So, I'm quite new and confused on the way to tackle creating sprites/sprite sheets for iOS games. I own the full CS5 sweet and have been told that fireworks is the best way to go for creating these (although I don't have the slightest idea in how yet and would love some tutorials/books specifying sprite sheet creation). My thoughts directed me towards tablet drawing, as I am awful at drawing with a mouse and/or tablet without a screen on it (such as a basic wacom). I was thinking about getting an iPad, as this would provide me with an iPad for testing purposes and a tablet. Does anyone know if it's possible (or even a good idea) to draw out your sprites on the iPad. Is it possible to export them out into Fireworks and such?

• [FreeBSD kernel ]How to maintain a linked list on kernel lever?

  - by Andy Leman

  The situation is: I will implement sets of new system calls. Each of them need to access (read or write) a linked list. So, that means I will have several C programs. So, how can I maintain a linked list in memory and let several programs access it? Or,this is wrong....I should save it as a file? (but I hardly think this is a good idea).. A lot of confused questions here...Need help. Thank you indeed!

• Is git svn rebase required before git svn dcommit?

  - by allyourcode

  I'm reading about using git as an svn client here: http://learn.github.com/p/git-svn.html That page suggests that you do git svn rebase before git svn dcommit, which makes perfect sense; it's like doing svn update before doing svn commit. Then, I started looking at the documentation for git svn dcommit (I was wondering what the 'd' is about): http://www.kernel.org/pub/software/scm/git/docs/git-svn.html You have to scroll down a bit to see the documentation on dcommit, which says this: Commit each diff from a specified head directly to the SVN repository, and then rebase or reset (depending on whether or not there is a diff between SVN and head). This confuses me, because if you do as the first page says, there will be no changes to pull down from svn once the first part of dcommit finishes. I'm also confused by the part that talks about reset; isn't git reset for removing changes from the staging area? Why would rebase or reset follow (the first part of) a dcommit?

• 3-Tier architecture-layering and the term-mishmash

  - by Rookian

  Hi! I am confused about the different possibilities to express a 3-Tier architecture. Data-Access-Layer Business-Layer Presentation Layer (User Interface) or Database (aka Backend) Business-Layer Presentation Layer (User Interface) Why can you skip the database in the 1st approach? Both use a database! Does the database belong to the layering or not?! What is wrong and what is right? Can someone of you clarify this :)? Thanks in advance!

• When to use MVC Scaffolding via NuGet vs MVC Scaffolding via MVC3 Tools Update

  - by James

  I am a little confused about the various different "mainstream" scaffolding options for MVC3. There is a NuGet package called MVCScaffolding. It first showed up in Jan 2011, but seems to be active and have recent updates, and be developed by Scott Hanselman, among others. Then in May 2011 came the MVC3 Tools Update. This seems like it incorporated the original scaffolding ideas into an "out of the box" scaffolding options. However, this has not been updated since. So - what is the relationship between these two scaffoldings (if any). Are there cases when one should be used over the other, or is it just a matter of taste? Does Visual Studio 2012 or MVC4 change the game on any of this? Thanks for any input.

• python: strange behavior about exec statement

  - by ifocus

  exec statement: exec code [ in globals[, locals]] When I execute the following code in python, the result really confused me. Some of the variables were setup into the globals, some were setup into the locals. s = """ # test var define int_v1 = 1 list_v1 = [1, 2, 3] dict_v1 = {1: 'hello', 2:'world', 3:'!'} # test built-in function list_v2 = [float(x) for x in list_v1] len_list_v1 = len(list_v1) # test function define def func(): global g_var, list_v1, dict_v1 print 'access var in globals:' print g_var print 'access var in locals:' for x in list_v1: print dict_v1[x] """ g = {'__builtins__': __builtins__, 'g_var': 'global'} l = {} exec s in g, l print 'globals:', g print 'locals:', l exec 'func()' in g, l the result in python2.6.5: globals: {'__builtins__': <module '__builtin__' (built-in)>, 'dict_v1': {1: 'hello', 2: 'world', 3: '!'}, 'g_var': 'global', 'list_v1': [1, 2, 3]} locals: {'int_v1': 1, 'func': <function func at 0x00ACA270>, 'x': 3, 'len_list_v1': 3, 'list_v2': [1.0, 2.0, 3.0]} access var in globals: global access var in locals: hello world ! And if I want to setup all variables and functions into the locals, and keep the rights of accessing the globals. How to do ?

• Android: various questions about GPS

  - by wei

  I'm writing my first location based android app, but got confused about some of the GPS service api. Here are some questions I have: 1) To get my current location, I called requestLocationUpdates() with a listener in the onCreate() method of one activity. But what happens when another activity starts and the current activity goes invisible? Is the GPS location update going to stop? If so, how do I keep it on after the activity is switched? 2) how accurate is the Location.getSpeed()? How is it computed? Can it tell the difference between on bicycle and on foot? 3) not really a question about android. How to calculate the coordinates of a location, say, 100m away from my current location? 4) To stop the GPS, I only need to remove all the listeners that have been registered to locationmanager? Thanks a lot!

• Moving to OOP hopefully!

  - by Luke

  So I am trying to understand OOP more and use it. The following code was written before i started using OOP. //loop through all the users $game = "$_POST[Game]_teams"; $result = mysql_query("SELECT username FROM `users`") or die(mysql_error()); while( $row=mysql_fetch_assoc($result) ) { $u[] = $row['username']; } I have put the query into my database page like following: function selectAllUsers() { $q = "SELECT username FROM ".TBL_USERS.""; mysql_query($q, $this->connection); } I'm a little confused about how the rest could be different? Would it be? Is it possible for anyone to help me without more code or understanding of my structure?

• Need example of how to create/manipulate image pixel data with iPhone SDK

  - by whiskeyspider

  Looking for a simple example or link to a tutorial. Say I have a bunch of values stored in an array. I would like to create an image and update the image data from my array. Assume the array values are intensity data and will be updating a grayscale image. Assume the array values are between 0 and 255 -- or that I will convert it to that range. This is not for purposes of animation. Rather the image would be updated based on user interaction. This is something I know how to do well in Java, but am very new to iPhone programming. I've googled some information about CGImage and UIImage -- but am confused as to where to start. Any help would be appreciated.

• Drupal Hierarchical Content

  - by Vecta

  I am currently looking at using either the Taxonomy or CCK module on my Drupal site as a means to create a hierarchical system. However, I'm a little confused on which one would best suit my needs, or if there is something else that would work better. Basically, there will be probably 70 or so "mini-sites" on the website I'm working on, each with a landing page and about 5 sub-pages of detailed information. I need a way to mark those sub-pages as being sub-pages of their parent page, as well as create a menu system to navigate between them. What is the best way this could be done? Thanks for your input!

• Buy or build tool for Data Reporting ?

  - by Manoj

  We have been asked to provide a data reporting solution. The followng are the requirements: i. The client has a lot of data which is generated everyday as an outcome of the tests they run. These tests are run at several sites and they get automatically backed up into a central server. ii. They already have perl scripts which post process them and generates excel based reports. iii. They need a web based interface for comparing those reports and they need to mark and track issues which might be present in those data. I am confused if we should build our own tool for this or we should go for already exiting tool(any suggestions?). Can you please provide supportive arguments for the decision that you would suggest?

• Your Django Development process/steps (Step by Step)

  - by AJ

  I want to know step by step process of how folks develop on Django here. I have seen that whenever I try to create a website in Django, I always get confused amongst: DB Schema/models.py UI/Template Structure Login module urls.py views.py How do you approach this? I may have missed something. You do not need to elaborate everything, just stepwise what you do. If you do two things at the same time (or side-by-side), that would also be helpful to mention. Thanks a lot.

• Javascript function as a parameter to another function?

  - by Alex

  Hello there, I'm learning lots of javascript these days, and one of the things I'm not quite understanding is passing functions as parameters to other functions. I get the concept of doing such things, but I myself can't come up with any situations where this would be ideal? My question is: When do you want to have your javascript functions take another function as a parameter? Why not just assign a variable to that functions return value and pass that variable to the function like so: // Why not do this var foo = doStuff(params); callerFunction(foo); //instead of this callerFunction(doStuff); I'm confused as to why I would ever choose to do things as in my second example. Why would you do this? What are the use cases? Thanks!!

• automake and custom rpath

  - by scai

  I have to ship a third-party library with an application. Because I don't want to set LD_LIBRARY_PATH by hand or require any wrapper script I want automake to set a custom rpath. Unfortunately libtool has its own -rpath option and adding -Wl,-rpath,/foo/bar to LDFLAGS only results in g++: unrecognized option '-rpath' because libtool seems to get confused with the command line options. The same happens with the alternative form -Wl,-rpath -Wl,/foo/bar. Is there any way to specify a custom rpath without libtool interference?

• why this assembly program is loaded from the address 0B3D:0000?

  - by viperchaos

  I have seen a assembly program written from a book about assemble: assume cs:code code segment dw 0123h,0456h,0789h,0abch,0defh,0fedh,0cbah,0987h mov bx,0 mov ax,0 mov cx,8 s: add ax,cs:[bx] add bx,2 loop s mov ax,4c00h int 21h code ends end This program's function is to add eight numbers. The author compiled this program in the DOS and use the DEBUG to see how this program be loaded. The author use the R command and got that DS = 0B2DH ES = 0B2D SS = 0B3D CS = 0B3D IP = 0000 And then the author said that this program is loaded from the address 0B3D:0000. I'm a confused that why this program is loaded from the address 0B3D:0000? Is this because the existence of the Program Segment Prefix(PSP)? If the answer is the existence of the PSP, what is in the PSP?
