• How long was Microsoft working on .NET before they released it?

  - by Richard DesLonde

  With the whole CLI, CTS, CLS, etc., not only did they release a powerful platform/infrastructure, but they released all the specs that describe it etc. It supports potentially infinite myriad languages, platforms, etc. This seems like an insane amount of work, even for a behemoth like Microsoft - especially since it turns out they did a damn good job. How long were they working on this before releasing it (.NET 1.0)?

• How to mange big amount users at server side?

  - by Rami

  I built a social android application in which users can see other users around them by gps location. at the beginning thing went well as i had low number of users, But now that I have increasing number of users (about 1500 +100 every day) I revealed a major problem in my design. In my Google App Engine servlet I have static HashMap that holding all the users profiles objects, currenty 1500 and this number will increase as more users register. Why I'm doing it Every user that requesting for the users around him compares his gps with other users and check if they are in his 10km radius, this happens every 5 min on average. That is why I can't get the users from db every time because GAE read/write operation quota will tare me apart. The problem with this desgin is As the number of users increased the Hashmap turns to null every 4-6 hours, I thing that this time is getting shorten but I'm not sure. I'm fixing this by reloading the users from the db every time I detect that it became null, But this causes DOS to my users for 30 sec, So I'm looking for better solution. I'm guessing that it happens because the size of the hashmap, Am I right? I have been advised to use spatial database, but that mean that I can't work with GAE any more and that mean that I need to build my big server all over again and lose my existing DB. Is there something I can do with the existing tools? Thanks.

• Unit testing - getting started

  - by higgenkreuz

  I am just getting started with unit testing but I am not sure if I really understand the point of it all. I read tutorials and books on it all, but I just have two quick questions: I thought the purpose of unit testing is to test code we actually wrote. However, to me it seems that in order to just be able to run the test, we have to alter the original code, at which point we are not really testing the code we wrote but rather the code we wrote for testing. Most of our codes rely on external sources. Upon refactoring our code however, even it would break the original code, our tests still would run just fine, since the external sources are just muck-ups inside our test cases. Doesn't it defeat the purpose of unit testing? Sorry if I sound dumb here, but I thought someone could enlighten me a bit. Thanks in advance.

• What is a better language to use when building a database: Visual C# or Visual Basic (VB.net)? [on hold]

  - by user3413537

  I'm building a GUI and a database which is using SQL as a server (internal database not a web application). Which language is more of a "right tool" when it comes to building a not very structurally complicated database? What are the advantages and disadvantages of Visual C# / VB.net? I've been reading a lot of stuff online and they said that VB.net is not as capable and it doesn't have as much support as Visual C#, and it seems that VB.net is on a decline in terms of popularity.

• Which language is more suitable heavy file tasks?

  - by All

  I need to write a script (based on basic functions) to process /image/audio/video files. The process is mainly filesystem tasks and converts. The database of files has been stored by mysql. The script is simple but cause heavy tasks on the system; for example renaming/converting/copying thousands of file in a run. The script does not read the content of files into memory, it just manage the commands for sub-processes. The main weight is on the communication with filesystem. The script will be used regularly for new files. My concern is about performance. I am thinking of Shell script a complied language like C Please advise which programming language is more suitable for this purpose and why? UPDATE: An example is to scan a folder for images, convert them with ImageMagick, move files to destination folder, get file info, then update the database. As you can see, the process has no room for optimization, and most of languages have similar APIs for popular programs like ImageMagick, MySQL, etc. Thus, it can be written in any language. I just wish to reduce resource usage by speeding up the long loop. NOTE: I know that questions about comparing languages are not favorable, but I really had problem to choose, because the problems can appear in action.

• Is there a language more general than Lisp?

  - by Jon Purdy

  I've been programming for a long time, and writing in Lisp (well, mostly Scheme) for a little less. My experience in these languages (and other functional languages) has informed my ability to write clean code even with less powerful tools. Lisp-family languages have lovely facilities for implementing every abstraction in common use: S-expressions generalise structure. Macros generalise syntax. Continuations generalise flow control. But I'm dissatisfied. Somehow, I want more. Is there a language that's more general? More powerful? As great as Lisp is, I find it hard to believe no one has come up with anything (dare I say) better. I'm well aware that ordinarily a question like this ought to be closed for its argumentative nature. But there seems to be a broad consensus that Lisp represents the theoretical pinnacle of programming language design. I simply refuse to accept that without some kind of proof. Which I guess amounts to questioning whether the lambda calculus is in fact the ideal abstraction of computation.

• How can I sell a legacy program rewrite to the business?

  - by Wil

  We have a legacy classic ASP application that's been around since 2001. It badly needs to be re-written, but it's working fine from an end user perspective. The reason I feel like a rewrite is necessary is that when we need to update it (which is admittedly not that often) then it takes forever to go through all the spaghetti code and fix problems. Also, adding new features is also a pain since it was architect-ed and coded badly. I've run cost analysis for them on maintenance but they are willing to spend more for the small maintenance jobs than a rewrite. Any suggestions on convincing them otherwise?

• Stuff you should have learned in school but didn't pay attention to at the time

  - by HLGEM

  This question made me think that there was a better question to ask. What did you learn in school that you didn't care about at the time, but turned out to be useful or you had to relearn in the workplace because you had it in school, but didn't retain the information and you needed it? (I mean for software related jobs.) I think this might help college students identify some of what they really should be paying attention to while they are in school.

• Python or Ruby in 2011.

  - by Sleeper Smith

  What I'm really asking is, in the current services and technologies provided, which is a more "useful" language? Which one has more opportunity? Some background info first. I'm a .net C# dev for 5 years. Having done a few projects on Amazon AWS, I'm looking to start a few projects of my own. But Azure's too expensive, and AWS has too much management overhead. My current choice is Google App Engine and Python. Logical enough. But what I want to ask here is this: In Linux world, which is more useful? Recently heard about Heroku for Ruby. How viable is this? Looking at the pricing model indicates that it's more expensive. Which one has more up-to-date and exciting open source projects? For instance Trac is just plain out dated compared to Redmine. One of the big reason pulling me for Ruby is Redmine. Implementations? IronPython/IronRuby/JRuby etc etc. Which one is more standardised and more implementation agnostic? Which one is easier to port between Windows/Linux? Anyway, your input and thoughts are greatly appreciated. thanks.

• Should I use the cool, new and awesome stuff [closed]

  - by Ieyasu Sawada

  I'm in the field of Web Development. I follow a lot of awesome people on Twitter(Paul Irish, Alex Sexton, David Walsh, Rebecca Murphey, etc.) By following these people I'm constantly updated of the new and cool stuff in web development(backbone.js, angular.js, require.js, ember.js, jasmine, etc.) Now I'm creating a web application for a client and because of the different tools, libraries, plugins that I'm aware of I don't even know anymore when do I need to use those or do I even need those, or how do I even implement it in a sane way where I won't have to repeat myself(DRY). What's your advice on what I really need to do in order to become better. Do I really need to use these cool new tools or should I just stick with what I know for now and try to make my code better. Should I unfollow these people in order to not pollute my mind with stuff that I can't really use now because I don't have the necessary experience in order to use it. What sort of things should I really be focusing on for someone like me who has only about 2 years of experience in the field of web development.

• Is anyone doing "real" TDD with Visual-C++, and if yes, how do they do it?

  - by Martin

  Test Driven Development implies writing the test before the code and following a certain cycle: Write Test Check Test (run) Write Production Code Check Test (run) Clean up Production Code Check test (run) As far as I'm concerned, this is only possible if your development solution allows you to very quickly switch between the production and test code, and to execute the test for a certain production code part extremely quickly. Now, while there exist lots of Unit Testing Frameworks for C++ (I'm using Bost.Test atm.) it does seem that there doesn't really exist any decent (for native C++) Visual Studio (Plugin) solution that makes the TDD cycle bearable regardless of framework used. "Bearable" means that it's a one-click action to run a test for a certain cpp file without having to manually set up a separate testing project etc. "Bearable" also means that a simple test starts (linking!) and runs very quickly. So, what tools (plugins) and techniques are out there that make the TDD cycle possible for native C++ development with Visual Studio? Note: I'm fine with free or "commercial" tools. Please: No framework recommendations. (Unless the framework has a dedicated Visual Studio plugin and you want to recommend the plugin.) Edit Note: The answers so far have provided links on how to integrate a Unit Testing framework into Visual Studio. The resources more or less describe how to get the UT framework to compile and get your first Tests running. This is not what this question is about. I'm of the opinion that to really work productively, having the Unit Tests in a manually maintained(!), separate vcproj from your production classes will add so much overhead that TDD "isn't possible". As far as I am aware, you do not add extra "projects" to a Java or C# thing to enable Unit Tests and TDD, and for a good reason. This should be possible with C++ given the right tools, but it seems (this question is about) that there are very little tools for TDD/C++/VS. Googling around, I've found one tool, VisualAssert, that seems to aim in the right direction. However, afaiks, it doesn't seem to be in widespread use (compared to CppUnit, Boost.Test etc.). Edit: I would like to add a comment to the context for this question. I think it does a good summary of outlining (part of) the problem: (comment by Billy ONeal) Visual Studio does not use "build scripts" that are reasonably editable by the user. One project produces one binary. Moreover, Java has the property that Java never builds a complete binary -- the binary you build is just a ZIP of the class files. Therefore it's possible to compile separately then JAR together manually (using e.g. 7z). C++ and C# both actually link their binaries, so generally speaking you can't write a script like that. The closest you can get is to compile everything separately and then do two linkings (one for production, one for testing).

• How can I discourage the use of Access?

  - by Greg Buehler

  Lets pretend that a very large company (revenue numbers with more than 8 figures) is looking to do a refresh on a software system, particularly the dashboard used by employees. This system was originally put together in the early 1990's to handle inventory tracking and storage across a variety of facilities (10+). Since this large company is now in the process of implementing some of these inventory processes with SAP they are in need of a major refresh. The existing system: Microsoft Access project performs dashboard duties Unique shipping/receiving configurations at different facilities require unique forms and queries within the Access project Uses 3rd party libraries referenced by Access to directly interface with at control system (read: motors, conveyors, and counters) Individual SQL Server 2000 instances (some traces of pre-update SQL Server 6.0 documents) at each facility The Issue: This system started as a home brewed inventory tracking scheme with a single internal sponsor who is still in charge of the technical direction. The original sponsor prescribing the desired deliverables that are being called for in the current RFP. The RFP describes a system based around a single Access project. Any suggestion that Access is ill suited for a project of this scope are shot down under the reasoning that "it works for the scope now". Are there any case studies, notices, or statements that can be used to disuade this potential customer from repeating their mistake? Does Microsoft make any statements directly about when it is highly recommended to ditch Access?

• Class hierarchy problem in this social network model

  - by Gerenuk

  I'm trying to design a class system for a social network data model - basically a link/object system. Now I have roughly the following structure (simplified and only relevant methods shown) class Data: "used to handle the data with mongodb" "can link, unlink data and also return other linked data" "is basically a proxy object that only stores _id and accesses mongodb on requests" "it looks like {_id: ..., _out: [id1, id2,...], _inc: [id3, id4, ...]}" def get_node(self, id) "create a new Data object from the underlying mongodb" "each data object can potentially create a reference object to new mongo data" "this is needed when the data returns the linked objects" class Node: """ this class proxies linking calls to .data it includes additional network logic operations whereas Data only contains a basic database solution """ def __init__(self, data): "the infrastructure realization is stored as composition by an included object data" "Node bascially proxies most calls to the infrastructure object data" def get_node(self, data): "creates a new object of class Object or Link depending on data" class Object(Node): "can have multiple connections to Link" class Link(Node): "has one 'in' and one 'out' connection to an Object" This system is working, however maybe wouldn't work outside Python. Note that after reading links Now I have two questions here: 1) I want to infrastructure of the data storage to be replacable. Earlier I had Data as a superclass of Node so that it provided the neccessary calls. But (without dirty Python tricks) you cannot replace the superclass dynamically. Is using composition therefore recommended? The drawback is that I have to proxy most calls (link, unlink etc). Any thoughts? 2) The class Node contains the common method .get_node which is used to built new Object or Link instances after reading out the data. Some attribute of data decided whether the object which is only stored by id should be instantiated as an Object or Link class. The problem here is that Node needs to know about Object and Link in advance, which seems dodgy. Do you see a different solution? Both Object and Link need to instantiate one of all possible types depending on what the find in their linked data. Are there any other ideas how to implement a flexible Object/Link structure where the underlying database storage is isolated?

• To branch or not to branch?

  - by Idsa

  Till recently my development workflow was the following: Get the feature from product owner Make a branch (if feature is more than 1 day) Implement it in a branch Merge changes from main branch to my branch (to reduce conflicts during backward merging) Merge my branch back to main branch Sometimes there were problems with merging, but in general I liked it. But recently I see more and more followers of idea to not make branches as it makes more difficult to practice continuous integration, continuous delivery, etc. And it sounds especially funny from people with distributed VCS background who were talking so much about great merging implementations of Git, Mercurial, etc. So the question is should we use branches nowadays?

• Why does Javascript use JSON.stringify instead of JSON.serialize?

  - by Chase Florell

  I'm just wondering about "stringify" vs "serialize". To me they're the same thing (though I could be wrong), but in my past experience (mostly with asp.net) I use Serialize() and never use Stringify(). I know I can create a simple alias in Javascript, // either JSON.serialize = function(input) { return JSON.stringify(input); }; // or JSON.serialize = JSON.stringify; http://jsfiddle.net/HKKUb/ but I'm just wondering about the difference between the two and why stringify was chosen. for comparison purpose, here's how you serialize XML to a String in C# public static string SerializeObject<T>(this T toSerialize) { XmlSerializer xmlSerializer = new XmlSerializer(toSerialize.GetType()); StringWriter textWriter = new StringWriter(); xmlSerializer.Serialize(textWriter, toSerialize); return textWriter.ToString(); }

• Free Typescript editor with definition based code completion feature

  - by NagyI

  I know that a plugin for Visual Studio exists. However i can't afford VS so i'm looking for a free alternative which can be used to code TypeScript and aware of the .d.ts definition files and can do code completion based on them. I know that Sublime Text and VIM can do syntax highlighting with the correct language definition file. However the biggest advantage of Typescript for me is that ability to give code assistance while coding. Are you aware of any editor which can do this? I'm interested even if it's in an experimental state.

• coding after a couple beers

  - by Patrick

  Sometimes after work I'll come home and have a beer or two and I've found that once I have a beer in me, my desire to code drops precipitously. I'm not talking about getting hammered or anything, but I can't seem to get up the gumption to do any coding. I'm still fine to do other things, i.e.- paying bills, playing games, reading, etc, it's just coding. I know that some people prefer to code with some beer in them. Is this normal, or do I need to practice coding under the influence so if the need ever arises, I'm ready for it. (I will only be coding on pet projects, nothing serious while CUI)

• github team workflow - to fork or not?

  - by aporat

  We're a small team of web developers currently using subversion but soon we're making a switch to github. I'm looking at different types of github workflows, and we're not sure if the whole forking concept in github for each developer is such a good idea for us. If we use forks, I understand each developer will have his own private remote & local repositories. I'm worried it will make pushing changesets hard and too complex. Also, my biggest concern is that it will force each developer to have 2 remotes: origin (which is the remote fork) and an upstream (which is used to "sync" changes from the main repository). Not sure if it's such a easy way to do things. This is similar to the workflow explained here: https://github.com/usm-data-analysis/usm-data-analysis.github.com/wiki/Git-workflow If we don't use forks, we can probably get by fine by using a central repo creating a branch for each task we're working on, and merge them into the development branch on the same repository. It means we won't be able to restrict merging of branches and might be a little messy to have many branches on the central repository. Any suggestions from teams who tried both workflow?

• Career opportunities for mid-20 .Net developer

  - by Valera Kolupaev

  Recently, I have moved to Toronto and started exploring career opportunities here. My first impressions about .net developer/architect career are really controversial. Here options that comes to my mind right now: Grow as a developer, lead and solution architect in large and well-known company, like Logitech or IBM. Doing .net development medium size (10-30) software shops Joining some start-up guys First one, seems very bureaucratic with kills all programming fun, that is such valuable to me. And there is not a lot of start ups, that are based on MS technology stack. Good mid-size company seems like a best fit to me, since I can have a lot of fun, doing new projects. Previously I have been working at large (5000+) outsourcing provider as a .Net developer. I was kind of a 'vanilla' time, because our team were always doing massive scale projects from scratch, on latest .Net stack. I would really appreciate if you share pros and cons of path, that you have chosen and what you value most in your current project. I'll start: Pros for Mid-size You are really close to business and application consumers, without all bureaucratic papers Cons It seems, that career oportunities of vertical growth is rather limited, once I have to switch to my own company or join development team of some big players.

• JUnit Testing in Multithread Application

  - by e2bady

  This is a problem me and my team faces in almost all of the projects. Testing certain parts of the application with JUnit is not easy and you need to start early and to stick to it, but that's not the question I'm asking. The actual problem is that with n-Threads, locking, possible exceptions within the threads and shared objects the task of testing is not as simple as testing the class, but testing them under endless possible situations within threading. To be more precise, let me tell you about the design of one of our applications: When a user makes a request several threads are started that each analyse a part of the data to complete the analysis, these threads run a certain time depending on the size of the chunk of data (which are endless and of uncertain quality) to analyse, or they may fail if the data was insufficient/lacking quality. After each completed its analysis they call upon a handler which decides after each thread terminates if the collected analysis-data is sufficient to deliver an answer to the request. All of these analysers share certain parts of the applications (some parts because the instances are very big and only a certain number can be loaded into memory and those instances are reusable, some parts because they have a standing connection, where connecting takes time, ex.gr. sql connections) so locking is very common (done with reentrant-locks). While the applications runs very efficient and fast, it's not very easy to test it under real-world conditions. What we do right now is test each class and it's predefined conditions, but there are no automated tests for interlocking and synchronization, which in my opionion is not very good for quality insurances. Given this example how would you handle testing the threading, interlocking and synchronization?

• Finding the order of a set's elements

  - by Maciej Stachowski

  A little rephrased, in the form of a game, real-life problem: Suppose there is a set of elements {1, 2, ..., n}. Player A has chosen a single permutation of this set. Player B wants to find out the order of the elements by asking questions of form "Is X earlier in the permutation than Y?", where X and Y are elements of the set. Assuming B wants to minimize the amount of questions, how many times would he have to ask, and what would be the algorithm?

• What are some cool git or .gitignore tricks & best practices? [closed]

  - by 01walid

  Git is just awesome and fast VCS, however, knowing better this tool will help you incredibly increase your productivity and save your time. Here we can try to make a collection of tips, tricks and useful links to better take advantage of git, this question can have some more sub-questions, I mean: what are some usefull commands that reverse or rectify commits/adding/removing mistakes? what are .gitignore & Global .gitignore best practices? especially with private/secure files that contains passwords, api keys, local config and so on ... .gitignore first or git add <files> first? what are the advantages/disadvantages of both being the first/last. links to blog post, articles, would be sufficient. I thought every sub-question is not worthy opening a whole post each alone, I think centralizing these tips in one question post would help many people.

• How important are unit tests in software development?

  - by Lo Wai Lun

  We are doing software testing by testing a lot of I/O cases, so developers and system analysts can open reviews and test for their committed code within a given time period (e.g. 1 week). But when it come across with extracting information from a database, how to consider the cases and the corresponding methodology to start with? Although that is more likely to be a case studies because the unit-testing depends on the project we have involved which is too specific and particular most of the time. What is the general overview of the steps and precautions for unit-testing?
