• Finding Telecommuting Opportunities as a Recent College Graduate

  - by stanigator

  Reading the answers to hiring practices of remote vs. local employees and freelance programming sites, I would like to add this question to the mix. I am a recent college graduate from an electrical engineering background with 2 years worth of work terms in programming (C, C++, VBA, Matlab, etc.) while I was still in school. While I am interested in learning other software tools (such as Python, Ruby on Rails, Javascript, etc.), I want to use the tools I have now in a telecommuting role while I grow my toolset. Despite having 2 years of work experience (and I've lost track of when I have started programming), my status as a recent college graduate may be an obstacle of my credibility to compete for telecommuting (or in fact any) programming opportunities. I don't know how I can go about finding telecommute programming opportunities for someone with my situation. Overall, many of previous places I've worked at liked my work. What are your suggestions? Thanks in advance!

• Changing Filename Case with TortoiseSVN on Windows [migrated]

  - by Brad Turner

  I've been working on a development project using a Windows machine as a test server. Eventually, I'd like the "live" version to end up on a Linux machine. While trying to test on the Linux machine, it became apparent that I needed to change the case of several file names as Windows was case insensitive but Linux wasn't. When I changed the file name case in Windows, TortoiseSVN recognized that the file hand changed and marked my folders appropriately. However, when I tried to commit my changes, not only did TortoiseSVN tell me that no changes had been made, but it had actually reverted all of the file name changes I had made back to their original case. My question is, is there a simple way to alter the file name case from a Windows PC and have the changes appear in my repository? I'd like to avoid any kind of delete, commit, replace, commit scenario to keep my commits tidy if possible. Thanks!

• How can I test a parser for a bespoke XML schema?

  - by Greg B

  I'm parsing a bespoke XML format into an object graph using .NET 4.0. My parser is using the System.XML namespace internally, I'm then interrogating the relevant properties of XmlNodes to create my object graph. I've got a first cut of the parser working on a basic input file and I want to put some unit tests around this before I progress on to more complex input files. Is there a pattern for how to test a parser such as this? When I started looking at this, my first move was to new up and XmlDocument, XmlNamespaceManager and create an XmlElement. But it occurs to me that this is quite lengthy and prone to human error. My parser is quite recursive as you can imagine and this might lead to testing the full system rather than the individual units (methods) of the system. So a second question might be What refactoring might make a recursive parser more testable?

• What's an easy way to remember what the term 'memoization' means

  - by Evan Plaice

  I know this sounds like a strange question. Intuitively, I know what the concept of memoization means because I have used it in my code before I ever heard of the term. The problem is, I use it so rarely that I lose the association and have to look it up; and, it feels like technobabble (read. gibberish) every time I use it. I might as well be a 'turboenacabulator'. Is there an easy/simple way to describe how memoization works that relates to the word itself.

• How can I convince management to deal with technical debt?

  - by Desolate Planet

  This is a question that I often ask myself when working with developers. I've worked at four companies so far and I've become aware of a lack of attention to keeping code clean and dealing with technical debt that hinders future progress in a software app. For example, the first company I worked for had written a database from scratch rather than use something like MySQL and that created hell for the team when refactoring or extending the application. I've always tried to be honest and clear with my manager when he discusses projections, but management doesn't seem interested in fixing what's already there and it's horrible to see the impact it has on team morale. What are your thoughts on the best way to tackle this problem? What I've seen is people packing up and leaving. The company then becomes a revolving door with developers coming in and out and making the code worse. How do you communicate this to management to get them interested in sorting out technical debt?

• Why does java.util.ArrayList allow to add null?

  - by Alfredo O

  I wonder why java.util.ArrayList allows to add null. Is there any case where I would want to add null to an ArrayList? I am asking this question because in a project we had a bug where some code was adding nulls to the List and it was hard to spot where the bug was. Obviously a NullPointerException was thrown but not until another code tried to access the element. The problem was how to locate the code that added the null object. It would have been easier if the ArrayList throwed an exception in the code where the elements was being added.

• Running a compiled Java program

  - by Roshan George

  I have a question on a compiled Java program that I have written. I have a Java file that has three classes defined within it. When I compiled the program I got a total of four classes. How do I make this into a form where I can run my application just by clicking an icon or something, or by issuing just a single command. For example, if I make it as an exe file, it could run only on Windows, how do I make it into a form compatible with all Oses. And hoe?

• 12.04 on Pentium Dual Core with 1GB or ram running slow

  - by Alex

  hey i have a Lenovo Thinkpad Laptop with Ubuntu 12.04 installed. It runs slow. I tried "System profiler and Benchmark" to test the computer. but the application quits and closes after the first few benchmark test. before it even gets to the other tests. So i tried "Hardinfo" that installed on the Puppy Linux live cd. that did the same thing (the apps look just a like). the memory usage isnt the problem on this pc. its the cpu processes. just running the "system profiler" app that comes with ubuntu uses about 34% on each core, default with nothing running its 5-10% on each core. i cant really find what the deal is other than that ubuntu is a cpu hog. so im testing unity2D at the moment to see how it goes. if you have any other suggestions, feel free to answer this question. thanks

• How do I pitch ASP.NET over PHP to a potential client?

  - by roman m

  I work at a Microsoft shop doing mainly web development. We had a client who asked us to review (improve) the data model for his web app, but said that he wants to develop his app in PHP (he knows "a guy" who can do it). When I asked him why he wants to go with PHP, he gave me the standard set of arguments from the 90's: Microsoft is evil, and PHP is free Writing an ASP.NET app is more expensive (software-wise) Why would Facebook use PHP if it was a bad idea? [classic] He had a few more comments about the costs associated with going .NET. The truth is that "Microsoft is expensive" does not hold water any longer, with their "Express" suite, you can develop an ASP.NET app without paying anything for software. When it comes to hosting, you can save a few bucks with PHP over .NET, but that's a small fraction of the projected development costs (we quoted 10-15k). Going back to my question, what arguments would I give to a client in favor of ASP.NET over PHP? [please provide sources for quantitative claims]

• I studied electrical engineering. Can I work as a developer? [closed]

  - by FailedDev

  A while ago I finished my Msc in Electrical Engineering and started working as an engineering consultant where I mostly do development work. I am good at picking up languages/technologies tools. I have fiddled with C/C++/C#/perl/ant/bash/html/css etc. Although I have never had a complain for my work, rather the contrary, I just feel that some day, someone will ask me a real hard task which would maybe seem rather trivial for a computer scientist but hard for me. Should I read/do something to become a better developer. Should I pick up a book about design patterns or algorithms for example? Is this normal that I have this kind of "fear"? Sorry if this is the wrong place to post this question. Please notify me so I can close it if this is the case.

• Money in from website

  - by oshirowanen

  EDIT 1: It seems that paypals micropayment system is currently my best option to retaining as much of the $1 as possible. Does anyone know of a way to retain even more of the $1? ORIGINAL QUESTION: I need to receive money from users from my webpage. They will only pay very small amounts, i.e. $1 max, but the total will probably go upto $10,000.00. What is the best way to receive this money from a webpage? When I say "the best way", i mean a method of getting the money from where I lose as little of it as possible in terms of fees for receiving the money.

• Make a flowchart to demonstrate closure behavior

  - by thomas

  I saw below test question the other day in which the author's used a flow chart to represent the logic of loops. And I got to thinking it would be interesting to do this with some more complex logic. For example, the closure in this IIFE sort of boggles me. while (i <= qty_of_gets) { // needs an IIFE (function(i) promise = promise.then(function(){ return $.get("queries/html/" + product_id + i + ".php"); }); }(i++)); } I wonder if seeing a flowchart representation of what happens in it could be more elucidating. Could such a thing be done? Would it be helpful? Or just messy? I haven't the foggiest clue where to start, but thought maybe someone would like to take a stab. Probably all the ajax could go and it could just be a simple return within the IIFE.

• FAQ: Creating a new LDOM domain

  - by Owen Allen

  I got a question about creating LDOM domains: "I have a Server Pool set up, and I need to create a secondary LDom domain on a machine in the pool. When I click on the machine, though, the 'create logical domain' command is grayed out. The machine still has available CPU threads and free RAM. What's going on?" This one has an easy answer. In a Server Pool, the Create Logical Domain action is under the pool's actions, rather than the individual machine's actions. This is because the Server Pool decides where to put the new domain based on the Server Pool's placement policy. So, in this case, you need to select the Server Pool in the Assets section, and then create the new domain from there.

• Why is Cocoa using an old version of Unicode? [closed]

  - by Randy Marsh

  While I was searching for something in the Apple docs, I stumble on this: illegalCharacterSet Returns a character set containing values in the category of Non-Characters or that have not yet been defined in version 3.2 of the Unicode standard. On the Unicode website, I find that the latest version is 6.1.0. That's a lot of major versions higher than what Cocoa supports. Does somebody know why Apple doesn't upgrade their framework? My more important question is: Are there problems for not doing having support for Unicode 3.2+? Will I have problems reading Unicode files created on other systems with a more recent version of Unicode?

• Google ranking - Modal views - google analytics events [duplicate]

  - by minchiya

  This question already has an answer here: How to diagnose a search engine ranking drop? 5 answers I modified a site recently : - I added many google analytics events, to better understand user behaviour. - I added also two buttons on almost all the pages of the site. Those buttons show modal-views (I am using bootstrap) with questions about user opinion. This modals views are on almost all pages of the site. After this modification the ranking of the site decreased on google search from the second place to the seconde page :( Is it the events-collected or the model-views added ? If the model-views are the reason, then how to better do similar surveys ? Did you have please similar experience, or explanation to this ? Perhaps it is the effect of panda4 update. In this cas, what can I look for to improve the site. How to debug the problem/reasons ?

• Can't edit/drag-and-drop widgets in QtCreator in Unity, Gnome3 - ok

  - by Maksim

  I have QtCreator 2.4.1 (Qt 4.7.4) installed on Ubuntu 12.04 LTS x86. When I try to change UI - drag-and-drop any widget (buttons, label, etc.) it won't let me do it, like it's read-only. The icon when I drag is a circle with a line through it. I've found that problem in Unity and it's suggested to install Gnome3 shell - Can't edit/drag-and-drop widgets in QtCreator I tried to install Gnome3 and it works fine as expected. But the question, is there any other way to work proper with QtCreator in Unity?

• Which will be faster? Switching shaders or ignore that some cases don't need full code?

  - by PolGraphic

  I have two types of 2d objects: In first case (for about 70% of objects), I need that code in the shader: float2 texCoord = input.TexCoord + textureCoord.xy But in the second case I have to use: float2 texCoord = fmod(input.TexCoord, texCoordM.xy - textureCoord.xy) + textureCoord.xy I can use second code also for first case, but it will be a little slower (fmod is useless here, input.TexCoord will be always lower than textureCoord.xy - textureCoord.xy for sure). My question is, which way will be faster: Making two independent shaders for both types of rectangles, group rectangles by types and switch shaders during rendering. Make one shader and use some if statement. Make one shader and ignore that sometimes (70% of cases) I don't need to use fmod.

• What functionality should I use in OpenGL 2.0?

  - by Jeffrey

  Considering OpenGL 2.1, we all know that glBegin and glEnd are the devil. Should I use only VBO to render 3d primitives (I can't find VAO in that version, weren't there already?)? Should I still use the matrix stack (why not?)? Should I still use glFrustum? Can I take advantage of shaders in GLSL 1.20? Where can I find a tutorial for VBO in OpenGL 2.1 and the "correct" way of programming in it? Also how am I supposed to animate something. Like a cube moving around an object or a player moving in the scene (static vbo data + shader?)? Note: Take your time to answer this question, I'll accept an answer tomorrow.

• brackets in php templates

  - by Othman

  I have a script, and now it's the perfect time to have an option to change theme templates. I was looking forward to store these files in php files, or html files. with CSS file. I looked over some codes and I found that they use brackets to refer to the variable. Here's an example of a template block: <div class='block_div'> <center>{title}</center> {content} </div> I know that I can use PHP vars usering <?=$var;?>. However, I think the one above is better, and I looked over the web to find anything about it but I couldn't. My Question is how I can use these brackets in my php or html code. to let the user changing the template only not the code!

• What is considered to be a "modification" of sources under the BSD license?

  - by Den

  I have a question about the 3-clause BSD license based on it's Wiki description. It states: Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: ... What is understood by "modification"? Specifically I am interested whether any/all of the following is considered as such modification: 1) reading the original sources and then re-implementing; 2) reading the original sources, waiting for a year and then re-implementing something based on whatever you could remember; 3) direct and very significant "complete" refactoring of the original sources.

• How would you represent an object that can be of multiple types, when storing it as a document in MongoDB?

  - by blueberryfields

  Somewhat related to this question, say that I have an object category which, depending on which type of object I have, has different restrictions on what it contains. (if you can reword the previous sentence to make more sense I'd appreciate it) For example var SomeSchema = new Schema({ _id: ObjectID, [... large number of common fields ...] type: //Restricted somehow to members of a fixed array data: //depending on type, this might be restricted - sometimes an integer, sometimes array, etc... }); What's the idiosyncratic method for defining this type of schema? Is it appropriate to define a single schema, and handle the types inside of it's members, or am I better off with separate schema for each type?

• Studying computer science - what am I getting myself into?

  - by clankercrusher

  I'm a student considering the possibility of studying computer science. I've picked up programming indie games and websites as a hobby and I really enjoy it. Despite my fairly positive experience, I somehow get the feeling that computer science in the business world will be completely different than do-it-for-fun game making. Since I'm interested in the field and I'd like to study well, I want to prepare myself for the onslaught. (If that’s even possible) What are some of the most important principals I need to know if I decide to study computer science? What will I need to know about computer science that a University probably won't teach me? Is there any way I can get hands on experience before or while I'm at a University? What am I getting myself into? P.S. Is this the right stack exchange site for this type of question?
