• Programatically loading user controls

  - by PhilSando

  Today's little problem is that I am trying to load user controls from my codebehind like so: Dim myControl As UserControl = Page.LoadControl("~\Modules\Content.ascx")              Controls.Add(myControl)  On running the page myControl is no where to be seen. I wonder why that is? Well after a bit of thought the following come to mind... Am I using the correct code to insert the usercontrol? Is there an alternative available? Does the fact that the usercontrol has a page_load method make a difference? Does the fact that the usercontrol is being called from the page_init method make a difference? Do I need to register the control in my aspx page at design time? I'll be looking to answer these questions as the day goes on!

• Dropbox icon dissapears right after login

  - by garvamel

  Even though Dropbox's app indicator dissapearing from the tray area seems like a recurrent enough problem, my issue is a litte different. When I login, I can see the app panel populating, and the dropbox icon does indeed appear (config'd as startup application), but after some other icons show up (bluetooth, battery, etc.) it's gone. It's still running though. I'm guessing it's having issues with staying pinned, and I don't know how to start addressing this problem. I have tried many if not all solutions provided here in the forums for the "icon missing" questions. So far: I've whitelisted everything regarding panel Uninstalled-reinstalled (with and without rebooting in between) Overwritten current installation Purged installation from terminal Installed from Software Center and from .deb file batch deleted every "dropbox" ocurrences from terminal (files and folders) and reinstalled Ran sudo apt-get install libappindicator1, it installed, but didn't solve anything I'm on Ubuntu 12.04 LTS - 64 bits. Any insight would me much appreciated!

• Can I use GPL software in a commercial application

  - by Petah

  I have 3 questions about the GPL here: If I use GPL software in my application, but don't modify or distribute it, do I have to release my application under the GPL? What if I modify some software that my application uses. Then do I have to release my application under the GPL, or can I just supply the modified software under the GPLs terms. And what if I use GPL software, but don't modify it, can I distribute it with my application? My case in point is, I have a PHP framework which I use the GeSHi library to highlight some output. Because GeSHi is GPL, does my framework have to be GPL? Can I modify GeSHi for particular use cases of my application if I supply the modifications back to the GeSHi maintainers? Can I redistribute my framework with GeSHi?

• PHP composer question

  - by kdub

  just getting started with composer and I have a couple of questions. When I use composer to add a dependency, the dependency gets added to my folder's Vendor directory. The newly added package not only comes with the source code for that package, but all packagist required files for the developer to test and add that package to packagist repo (composer.json, .travis.yaml, license, readme.md, etc). For my project, do I need to keep the vendor's required packagist files in my project? Can I clean the package folder structure up a little? I added the package, Slim micro framework, which nests the source files three directories deep upon installation, ../vendor/slim/slim/Slim/(source Files). Is it worth moving these files to the top Slim directory like: ../vendor/Slim/(source files)? Or will this ruin the integrity of the package?

• BDD in a .NET environment

  - by Nick

  I've seen BDD in action (in this case using SpecFlow and Selenium in a .NET environment) for a small test project. I was very impressed - mainly due to the fact that the language used to specify the acceptance tests meant they engaged with the product owner much more easily. I'm now keen to bring this into my current organisation. However I'm asked 'who else uses this?' and 'show me some case-studies'. Unfortunately I cannot find any 'big names' (or even 'small names' for that matter!) of companies who are actively using BDD. I have two questions really: Is BDD adopted by companies out there? Who are they? How can BDD be implemented in an agile .NET environment and are there any significant drawbacks to doing it?

• Learning the nuances of a language (C++)

  - by prelic

  So I'm a recent college graduate, and I really enjoy working in C++; I worked with it a lot in school, and would like to pursue a career writing in C or C++. The problem I'm having is that I'm trying to learn the nuances of C++. I'm not talking about the basics, or even advanced concepts like templates, namespaces, etc. I'm talking about the real nitty-gritty stuff like undefined behavior and stuff like that. When I'm interviewing, and they put a bizarre piece of C++ code in front of me, and ask me what the output will be, I want to be able to nail those questions. Obviously experience is a great way to learn, but when I write code for practice, I [obviously] know what it does. Reading open-source projects have been good practice, but I find that there tends to be an enormous learning curve just understanding the organization of the code (because the projects tend to be large). So basically what I'm asking is, what should I do now?

• The use of LGPL for Commercial use

  - by Smarty Twiti

  I am trying to make my first app for sale, I would like to ask some questions for those who have already sold their software: Have you used a Framework/Lib whose LGPL License? if yes, what are the impressions of your customers? for example, if your customers/ competitors from the market reveal technology/secrets that you used in your solution (as LGPL requires that you make a Dynamic Link (.DLL) for your libs and you clearly tell the use of a Lib/Framework ...). Full story: For my project, I used a framework LGPL/commercial (Dual License) the second one it was too expensive (about 3000 USD) which pushed me to use LGPL.. however I still concerned.. That is why I ask for advise and especially motivations... Please do not hesitate to participate... Thanks in advance.

• License for Opensource project

  - by asterisk

  I am newbie in the open source community world. I am planning to develop a open source project, hosted on github. The project would be using other open source components like- NHibernate, FNH, Log4net, CommonLibrary, Autofac, Quartz.Net Scheduler etc etc My questions are: Would there be any restrictions on using above OSS components? for example: I plan to use MIT license, but Quartz.Net Scheduler uses Apache license, would there be any restrictions? How do I get a license for my own project? Do I need to register my project somewhere? What is the best practice to mention credits to the OSS compoenents used? Many thanks,

• How much configurability to give to users regarding concurrency?

  - by rwong

  This question is a narrowing-down of these related questions: How much effort should we spend to programming for multiple cores? Concurrency: How do you approach the design and debug the implementation? Given that each user's computers may have different performance characteristics with respect to calculations, memory, disk I/O bandwidth and network I/O bandwidth, and that it is difficult to implement an automated self-tuning system in your software, how much configurability should we give to the end-users so that they can find ways (by trial-and-error?) to improve our software's efficiency? If we give users the ability to change these settings, how do we give visual feedback to users so they can measure the performance changes?

• From Imperative to Functional Programming

  - by user66569

  As an Electronic Engineer, my programming experience started with Assembly and continue with PL/M, C, C++, Delphi, Java, C# among others (imperative programming is in my blood). I'm interested in add to my previous knowledge, skills about functional programming, but all I've seen until now seems very obfuscated and esoteric. Can you please answer me these questions? 1) What is the mainstream functional programming language today (I don't want to get lost myself studying a plethora of FP languages, just because language X has the feature Y)? 2) What was the first FP language (the Fortran of functional programming if you want)? 3) Finally, when talking about pure vs. non pure FP what are the mainstream languages of each category? Thank you in advance

• How to choose, set and use keywords while structuring a website?

  - by mechdeveloper

  I have been working on my personal website for sometime, I think I have been doing a good technical job, but, unfortunately I did a terrible job while structuring the website because I didn't care about the keywords I was going to use. Although it is my personal website, I'd like to mention the main objective is the blog of the website, so I'd like that the keywords were related to the content that it is in the blog, at present google webmaster tools is displaying a lot of keywords that has nothing to do with the content of the website, and some SEO reporting websites such as woorank says that the keyword optimization of the website is awful, So I have 3 questions: How to choose, set and use keywords while structuring a website? OPTIONAL: which are all the methods and sources used by search engines to collect the keywords of a website? there are some high profile websites that aren't optimized on this as well, should I concerned about this anyway?, is there anything more important that I should be concerned about? (if you want to see the website please check my profile)

• Resources for a fighting game

  - by David

  As the title says, I need resources for a 2D fighting game for the PC. The game is being made by me and two close friends. I'm thinking of using the FlatRedBall engine and either Allegro Sprite Editor or Amiga DPaint for the sprites, but I don't know is there is anything better for a more or less beginner in video game making. So my questions are as follows, what would be the best engine to use so that we could also sell the game later on, (I don't really care what language I'd have to use) and what would be the best thing to use for sprite creating? I would really appreciate any help given.

• Any tips to learn how to program with severe ADHD?

  - by twinbornJoint

  I have a difficult time trying to learn how to program from straight text-books. Video training seems to work well for me in my past experiences with PHP. I am trying my hardest to stay focussed and push through. Specifically I am looking to start indie game development. Over the last two weeks I have been trying to pick the "right" language and framework to develop with. I started going through Python, but I am not really enjoying the language so far. I am constantly looking through this website to compare this language to that, and keep getting distracted. Aside from all of this, is it possible to become a programmer when you have trouble focussing? Has anyone been through this that can recommend some advice? edit - you guys can check my new question out with detailed information thanks to all of the responses from this thread. http://programmers.stackexchange.com/questions/15916/what-is-the-best-language-and-framework-for-my-situation

• What are the files in /dev/input/ and what they do?

  - by Pouya

  I'm fairly new to ubuntu and I've started to search around everywhere and check everything! Recently I saw these files at /dev/input/eventX, js0, mice, mouseX. By printing the output using "cat" I realized they are somehow responsible for mouse and keyboard input but the output had an strange character encoding (even for the keyboard). My questions are, what are these files and how can I interpret the data of these files? Are there any other places that I can access the input/output of my Ubuntu machine? And are there any ebooks, manual or something similar that I can check the duty and structure of ubuntu system files? (i.e. to find the answer of such question)

• how to convince other we should move to hadoop?

  - by Ramy

  Everything I've read about Hadoop seems like exactly the technology we need to make our enterprise more scalable. We have terabytes of raw data that is in non-relational form (text files of some kind). We're quickly approaching the upper limits of what our centralized file server can handle and everyone is aware of this. Most people on the tech team, especially the more junior members of the tech team are all in favor of moving from the central file system to HDFS. The problem is, there is one key (most senior, etc.) member of the team who is resisting this change and every time Hadoop comes up, he tells us that we could simply add another file server and be in the clear. So, my question (and yes, it's really subjective, but I need more help with this than any of my other questions) is what steps can we take to get upper management to move forward with Hadoop despite the hesitation of one member of the team?

• How can I make the unity sidebar visible permanently (as in, in all circumstances)?

  - by Doug

  Yes, I have seen the other similar questions; if this is a duplicate please link me to the question that answer this, because none of them appear to; all appear to only address (1) of the two issues below: There are TWO times when the sidebar will magically vanish: 1) By default when you move your cursor off it and focus on a different app. This is fixable by setting the auto hide behaviour, as described here: How to make the Unity launcher always visible? 2) When you move a window over / under it, or maximize a window. Even when the autohide setting is 'never' this will cause the sidebar to mysterious decide to hide itself. In fact, it doesn't appear what settings you change, this behaviour refuses to change. This is extremely undesired behaviour. I'm using a stock standard 11.10 install.

• how to deal with parallel programming

  - by nkint

  Hi. I know that parallel programming is a big resource in computer graphics, with moder machines, and mayebe a computing model that will be grow up in the near future (is this trend true?). I want to know what is the best way to deal with it. there is some practical general purpose usefulness in studying processor n-dimensional mesh, or bitonic sort in p-ram machines or it's only theory for domain specific hardware used in real particular signal elaborations of scientific simulations? Is this the best way to acquire the know how for how to become acquainted with cuda or opencl? (i'm interested in computer graphics applications) and why functional programming is so important to understand parallel computing? ps: as someone has advice me i have forked this discussion from http://stackoverflow.com/questions/4908677/how-to-deal-with-parallel-programming

• How to study for an Informatics Olympiad [on hold]

  - by Cloud

  One of my goals for next year is to participate in the Australian Informatics Olympiad. As far as I'm aware, it is not too different from Informatics Olympiads in other countries. What would be the best way to study for this? What content should I pay particular attention to while learning in Python? I am currently using the book 'Learn Python the hard way', but are there any other books worthy of a mention? This is the link to their site: http://orac.amt.edu.au/aio/ It contains sample questions, so you can get an idea for the structure or nature of the competition. I know this isn't really a specific programming question, but it would be great if someone could share their experience or give some suggestions for me.

• Software Center doesn't ask for a password anymore

  - by Jeff

  So, out of the blue, software-center stopped asking me for a password. It just runs, and then turns grey. Works fine as root, or with sudo. While investigating, I found out about polkit (new to me), and looked at the policies, which seem fine. Looking under localauthority, however, showed that while the sub-directories (10-, 20-, 30-, 50-, 90-) are there, there aren't any files under those. Is that my problem? Should there be a file in the 50-local.d? Or am I still looking in the wrong place for my problem? I looked for similar questions and looked at the answers, but they don't really help any. One other thing, I'm not sure it's related but seemed to happen about the same time: The Dash Home only shows items for recent files and downloads. Nothing anywhere else anymore.
