• Bad at math, feeling limited

  - by Peter Stain

  Currently I'm a java developer, making websites. I'm really bad at math, in high school I got suspened because of it once. I didn't program then and had no interest in math. I started programming after high school and started feeling that my poor math skills are limiting me. I feel like the programming's not that hard for me. Though web development in general is not that hard, i guess. I've been doing Spring and Hibernate a lot. What i'm trying to ask is : if I understand and can manage these technologies and programming overall, would it mean that I have some higher than average prerequisite for math and details? Would there be any point or would it be easy for me to take some courses in high school math and get a BSc in math maybe? This web development is really starting to feel like not my cup of tea anymore, i would like to do something more interesting. I'm 25 now and feel like stuck. Any help appreciated.

• What is the way to understand someone else's giant uncommented spaghetti code? [closed]

  - by Anisha Kaul

  Possible Duplicate: I’ve inherited 200K lines of spaghetti code — what now? I have been recently handled a giant multithreaded program with no comments and have been asked to understand what it does, and then to improve it (if possible). Are there some techniques which should be followed when we need to understand someone else's code? OR do we straightaway start from the first function call and go on tracking next function calls? C++ (with multi-threading) on Linux

• Strategy for managing lots of pictures for a website

  - by Nate

  I'm starting a new website that will (hopefully) have a lot of user generated pictures. I'm trying to figure out the best way to store and serve these pictures. The CMS I'm using (umbraco) has a media library that puts a folder on the server for each image. Inside of there you can have different sizes of that same image. That folder has an ID on it and the database has additional information for that image along with the ID of the folder. This works great for small sites, but what if the pictures get up to 10,000, 100,000 or 1,000,000? It seems like the lookup on the directory would take a long time to find the correct folder. I'm on windows 2008 if that makes a difference. I'm not so worried about load. I can load balance my server pretty easily and replicate the images across the servers. The nature of the site won't have a lot of users on it either, but it could have a lot of pics. Thanks. -Nate EDIT After some thought I think I'm going to create a directory for each user under a root image folder then have user's pictures under that. I would be pretty stoked if I had even 5,000 users, so that shouldn't be too bad of a linear lookup. If it does get slow I will break it down into folders like /media/a/adam/image123.png. If it ever gets really big I will expand the above method to build a bigger tree. That would take a LOT of content though.

• Do immutable objects and DDD go together?

  - by SnOrfus

  Consider a system that uses DDD (as well: any system that uses an ORM). The point of any system realistically, in nearly every use case, will be to manipulate those domain objects. Otherwise there's no real effect or purpose. Modifying an immutable object will cause it to generate a new record after the object is persisted which creates massive bloat in the datasource (unless you delete previous records after modifications). I can see the benefit of using immutable objects, but in this sense, I can't ever see a useful case for using immutable objects. Is this wrong?

• How do you approach tutorials

  - by aurel

  Hi I get lots of interesting tutorials through feeds and sometimes I implement them step by step, other times I just read through them and note anything that I do not know. when ever I implement them I takes a long time - starting the project, typing the code (as I feel there is no point to copy and paste ), then going back and forth between browser and editing program All in all, I am interested to know how do you learn from the tutorials (I'm no where close to being an expert). Or if you don't use tutorials, is there any other way to learn? Thanks a lot

• Validating allowed characters or validating disallowed characters

  - by Tom

  I've always validated my user input based on a list of valid/allowed characters, rather than a list of invalid/disallowed characters (or simply no validation). It's just a habit I picked up, probably on this site and I've never really questioned it until now. It makes sense if you wish to, say, validate a phone number, or validate an area code, however recently I've realised I'm also validating input such as Bio Text fields, User Comments, etc. for which the input has no solid syntax. The main advantage has always seemed to be: Validating allowed chars reduces the risk of you missing a potentially malicious character, but increases the risk the of you not allowing a character which the user may want to use. The former is more important. But, providing I am correctly preventing SQL Injection (with prepared statements) and also escaping output, is there any need for this extra barrier of protection? It seems to me as if I am just allowing practically every character on the keyboard, and am forgetting to allow some common characters. Is there an accepted practice for this situation? Or am I missing something obvious? Thanks.

• A new CAPTCHA using sentences?

  - by Xeoncross

  I was just thinking about how recaptcha is getting harder when I thought about another posible solution. Images won't last forever so we will need something else some day - like human logic or emotion. Google and others are trying grouping images by category (find the image that doesn't belong) but that requires a large amount of images and doesn't work for the blind. Anyway, what if a massive collection of text was gathered (public-domain books from each language) and a sentence was shown to the user with 1 (or 2) words that were a select box of choices? Only computers that knew correct English/Spanish/German grammar would be able to tell which of the words belonged in the sentence. Would there be any problems with this approach? I would assume that it would be easy enough for anyone that knew the language that the sentense was displayed in to figure out the answer easier than trying to read the reCAPTCHA text. Plus, storing an insane number of sentences would only take a couple gigabytes of space and wouldn't take anywhere near the CPU time creating images/audio takes. In other words, anyone could host their own captcha system with minimal impact on system performance. Is there a problem with this approach? More specifically I'm looking for the main problem with this approach. migrated from stackoverflow

• Is there an open source license for this?

  - by Philip

  I have written code at home, on my own time and using my own knowledge and equipment, while under no contract or NDA. I want to make this code open source so that I can use it in software I write for an employer, without denying myself the right to use it at home or elsewhere later. I'm not sure if saying it is in the "public domain" would fit this purpose, or if I need to find an open source license. I want anyone to be able to use the code in closed source proprietary software with zero requirements for including a license with the source or binary. And I want to minimize the risk of anyone being sued for using it. (I'm aware that one can never be 100% safe from being sued.) Is there an open source license that fits this purpose? To what extent is what I want to do even possible? I wouldn't mind putting the license in comments in the code files themselves, but that obviously doesn't go with the binary.

• How to refactor an OO program into a functional one?

  - by Asik

  I'm having difficulty finding resources on how to write programs in a functional style. The most advanced topic I could find discussed online was using structural typing to cut down on class hierarchies; most just deal with how to use map/fold/reduce/etc to replace imperative loops. What I would really like to find is an in-depth discussion of an OOP implementation of a non-trivial program, its limitations, and how to refactor it in a functional style. Not just an algorithm or a data structure, but something with several different roles and aspects - a video game perhaps. By the way I did read Real-World Functional Programming by Tomas Petricek, but I'm left wanting more.

• Is there a better approach to speech synthesis than text-to-speech for more natural output? [closed]

  - by Anne Nonimus

  We've all heard the output of text-to-speech systems, and for anything but very short phrases, it sounds very machine-like. The ultimate goal of speech synthesis systems is to pass a Turing test of hearing. Clearly, the state of the art in text-to-speech has much to improve. However, speech synthesis isn't restricted to just text-to-speech systems, and I'm wondering if other approaches have been tried with better success. In other words, has there been any work done (libraries, software, research papers, etc.) on natural speech synthesis other than text-to-speech systems?

• Is it possible to migrate struts/spring based application to GWT?

  - by Satish Pandey

  I am using the combination of spring, spring-security, struts and iBatis in my application. Now I am looking to migrate the struts UI to GWT. The new combination must be spring, spring-security, GWT and iBatis. I applied a layered approach to develop my application. In Controller/UI layer i am using Struts. I want to replace struts and use GWT in Controller/UI layer. Is is possible to use GWT without affecting another layers DAO/BL/SL?

• What happens if you're unable to solve a problem?

  - by gablin

  I'm a year away from graduating from university, and I'm really looking forward to solving practical problems. Especially non-trivial ones which require a bit of research and a lot of thinking. But at the same time, that is also my greatest fear - being faced with a problem that I'm unable to solve, no matter how hard I try. And with pressure to deliver code on impending deadlines just around the corner, it does look a bit scary when viewing it from the safe playgrounds on uni (where the worst thing that can happen is that you have to redo a course or exam). So for those who have been in industry for any longer length of time, what would happen if you were told to solve a problem that you couldn't? Has it happened, and if so, what did happen? Did they just drop it and said "Oh well, guess we can make do with something else"? Were there consequences? Were you reprimanded, or even fired?

• Is Java free/open source or it isn't?

  - by user1598390

  On November 13, 2006, Sun released much of Java as free and open source software, (FOSS), under the terms of the GNU General Public License (GPL). On May 8, 2007, Sun finished the process, making all of Java's core code available under free software/open-source distribution terms, aside from a small portion of code to which Sun did not hold the copyright. OpenJDK (Open Java Development Kit) is a free and open source implementation of the Java programming language. It is the result of an effort Sun Microsystems began in 2006. The implementation is licensed under the GNU General Public License (GNU GPL) with a linking exception. Why there are still people that say Java is not open source or free as in free speech ? Am I missing something? Is Java still privative ?

• Cuda vs OpenCL - opinions

  - by Martin Beckett

  Interested in peoples opinions of Cuda vs openCL following NVidia's Cuda4 release. I had originally gone with openCL since cross platform, open standards are a good thing(tm). I assumed NVidia would fall into line as they had done with openGL. But having talked to some NVidia people, they (naturaly) claim that they will concentrate on CUDA and openCL is hampered by having committees and having to please everyone - like openGL. And with the new tools and libs in CUDA it's hard to argue with that. -I'm in a fairly technical market so I can require the users to have particular HW.

• Is it just me or is this a baffling tech interview question

  - by Matthew Patrick Cashatt

  Background I was just asked in a tech interview to write an algorithm to traverse an "object" (notice the quotes) where A is equal to B and B is equal to C and A is equal to C. That's it. That is all the information I was given. I asked the interviewer what the goal was but apparently there wasn't one, just "traverse" the "object". I don't know about anyone else, but this seems like a silly question to me. I asked again, "am I searching for a value?". Nope. Just "traverse" it. Why would I ever want to endlessly loop through this "object"?? To melt my processor maybe?? The answer according to the interviewer was that I should have written a recursive function. OK, so why not simply ask me to write a recursive function? And who would write a recursive function that never ends? My question: Is this a valid question to the rest of you and, if so, can you provide a hint as to what I might be missing? Perhaps I am thinking too hard about solving real world problems. I have been successfully coding for a long time but this tech interview process makes me feel like I don't know anything. Final Answer: CLOWN TRAVERSAL!!! (See @Matt's answer below) Thanks! Matt

• Is there a canonical book for learning Java as an experienced developer?

  - by Steven Elliott Jr

  I have been a .NET developer now for about the past 5/6 years give or take. I have never done any professional Java development and the last time I really touched it was probably back in college. I have been toying with the Scala language a little bit but nothing serious. Recently, I've been offered an opportunity to do some pretty cool work, but using Java instead of .NET. I think I can get by alright with my current skill set, meaning I already know how to program well and am familiar with languages such as C# and C++, etc. So, the syntax and all that language stuff are really not a problem. What I need is a really good reference book and a book about how to think in Java. Each language/Framework/Stack tries to address things a certain way and I'm sure Java is no different. What are some great Java books that you simply can't live without? Are there any books that talk about the most important parts of Java that must be understood before all else? As a side note, I will be doing mostly Java web development. Not really 100% on what types of stuff they are using for persistence, framework, server, etc.

• What is enterprise software, exactly?

  - by good_computer

  I don't understand the difference between "normal" software and enterprise software. Even after reading these... "Enterprise Software" on Wikipedia "Enterprise Software Is Sexy Again" on Techcrunch "The Great Enterprise Software Swindle" on Coding Horror I can't really wrap my head around the real differences. Is there any difference at all between the two? Why do people say enterprise software sucks?

• What are your advice, methods, or practices to take out the most from a day on-site at a customer?

  - by Stephane

  We just deployed a large software that affects the way the user work-day looks like in many aspects. It changes a lot of things in the way they interact between eachothers. The developers of the team are taking rounds and spending one day at the customer's site to understand better what is a typical day for our user, and the learning process they go through. In this context, what How would you approach that day, what kind of questions do you ask, how do you observe the user. Are there defined practices that exist? Also what wouldn't you do? Did you have some bad experience out of this?

• Why was Android's ContentProvider created?

  - by satur9nine

  The title sums up my question, but to elaborate basically what I want to understand is why the Android designers want apps that need to work with shared data to use a Content Provider rather than just accessing the SQLite database directly? The only reason I can think of is security because certain files can by accessed only be certain processes and in that way the Content Provider is the gatekeeper that ensures each app has the proper privileges before allowing read and/or write access to the database file. Is that the primary reason why ContentProvider was created?

• Can WinRT really be used at just the boundaries?

  - by Bret Kuhns

  Microsoft (chiefly, Herb Sutter) recommends when using WinRT with C++/CX to keep WinRT at the boundaries of the application and keep the core of the application written in standard ISO C++. I've been writing an application which I would like to leave portable, so my core functionality was written in standard C++, and I am now attempting to write a Metro-style front end for it using C++/CX. I've had a bit of a problem with this approach, however. For example, if I want to push a vector of user-defined C++ types to a XAML ListView control, I have to wrap my user-defined type in a WinRT ref/value type for it to be stored in a Vector^. With this approach, I'm inevitably left with wrapping a large portion of my C++ classes with WinRT classes. This is the first time I've tried to write a portable native application in C++. Is it really practical to keep WinRT along the boundaries like this? How else could this type of portable core with a platform-specific boundary be handled?

• How to manage an issue tracker's backlog

  - by Josh Kelley

  We've been dutifully using Trac for several years now, and our "active tickets" list has grown to almost 200 items. These include bugs that are too low priority and too complicated to fix for now, feature requests that have been deferred, issues that have never really generated complaints but everyone agrees ought to be fixed someday, planned code refactorings and other design infelicities that we don't want to lose track of, etc. As a result, with almost 200 of these issues, the list is almost overwhelming; it's no longer useful as a source of what needs to be worked on right now. What's the best way to keep track of issues of this sort? Part of the problem is that some of these issues are such a low priority that they may never get done. I hate to lose track of these items (similar to not wanting to throw something out of my house in case I might need it someday); do I need to throw them out regardless (by marking them as wontfix) and assume I can find them in the future if I ever do need them?

• Understanding branching strategy/workflow correctly

  - by burnersk

  I'm using svn without branches (trunk-only) for a very long time at my workplace. I had discovered most or all of the issues related to projects which do not have any branching strategy. Unlikely this is not going to change at my workplace but for my private projects. For my private projects which most includes coworkers and working together at the same time on different features I like to have an robust branching strategy with supports long-term releases powered by git. I find out that the Atlassian Toolchain (JIRA, Stash and Bamboo) helped me most and it also recommending me an branching strategy which I like to verify for the team needs. The branching strategy was taken directly from Atlassian Stash recommendation with a small modification to the hotfix branch tree. All hotfixes should also merged into mainline. The branching strategy in words mainline (also known as master with git or trunk with svn) contains the "state of the art" developing release. Everything here was successfully checked with various automated tests (through Bamboo) and looks like everything is working. It is not proven as working because of possible missing tests. It is ready to use but not recommended for production. feature covers all new features which are not completely finished. Once a feature is finished it will be merged into mainline. Sample branch: feature/ISSUE-2-A-nice-Feature bugfix fixes non-critical bugs which can wait for the next normal release. Sample branch: bugfix/ISSUE-1-Some-typos production owns the latest release. hotfix fixes critical bugs which have to be release urgent to mainline, production and all affected long-term *release*es. Sample branch: hotfix/ISSUE-3-Check-your-math release is for long-term maintenance. Sample branches: release/1.0, release/1.1 release/1.0-rc1 I am not an expert so please provide me feedback. Which problems might appear? Which parts are missing or slowing down the productivity?

• When would I use pseudocode instead of flowchart?

  - by user1276078

  I'm a student working with various techniques of programming, and I've come across pseudocode and flowchart. I know that these are both used in order to think through the problem before actually programming, but I have a few questions with this. When would I use pseudocode to plan out and when would I use flowcharts? Or is it better to do both before actually programming. Particularly for a small arcade sort of game in JAVA since that is my next project. I've noticed that pseudocode is very similar to the actual code rather than flowcharts. Would this make pseudocoding better because you essentially copy/paste the pseudocode into your program (of course, you have to change it to fit the language. I understand that part). Is it practical to use both of these while programming? Particularly the same game mentioned earlier. Thanks.

• What tasks should an Architect NOT do or limit to be effective?

  - by GBH

  There are plenty of questions/answers about what an architect does, but what should someone in an Architect role NOT do? What are the boundaries/limits to maintain to be an effective Architect? I'm thinking here of Architect vs Developer and Architect vs Project Manager For example, I'm finding myself in a role where my title is Architect but I am also the coding/development lead and project manager on multiple small enterprise projects. I'm struggling with all the task switching and now I want to limit task switching. Trying to wear every hat just isn't working. What tasks should an Architect not do at all? What tasks should an Architect limit? I do think an Architect needs to keep coding, but how to define an appropriate limit for coding work?

• PHP MYSQL loop to check if LicenseID Values are contained in mysql DB [closed]

  - by Jasper

  I have some troubles to find the right loop to check if some values are contained in mysql DB. I'm making a software and I want to add license ID. Each user has x keys to use. Now when the user start the client, it invokes a PHP page that check if the Key sent in the POST method is stored in DB or not. If that key isn't store than I need to check the number of his keys. If it's than X I'll ban him otherwise i add the new keys in the DB. I'm new with PHP and MYSQL. I wrote this code and I would know if I can improve it. <?php $user = POST METHOD $licenseID = POST METHOD $resultLic= mysql_query("SELECT id , idUser , idLicense FROM license WHERE idUser = '$user'") or die(mysql_error()); $resultNumber = mysql_num_rows($resultLic); $keyFound = '0'; // If keyfound is 1 the key is stored in DB while ($rows = mysql_fetch_array($resultLic,MYSQL_BOTH)) { //this loop check if the $licenseID is stored in DB or not for($i=0; $i< $resultNumber ; i++) { if($rows['idLicense'] === $licenseID) { //Just for the debug echo("License Found"); $keyFound = '1'; break; } //If key isn't in DB and there are less than 3 keys the new key will be store in DB if($keyfound == '0' && $resultNumber < 3) { mysql_query( Update users set ...Store $licenseID in Table) } // Else mean that the user want user another generated key (from the client) in the DB and i will be ban (It's wrote in TOS terms that they cant use the software on more than 3 different station) else { mysql_query( update users set ban ='1'.....etc ); } } ?> I know that this code seems really bad so i would know how i can improve it. Someone Could give me any advice? I choose to have 2 tables: users where all information about the users is, with fields id, username, password and another table license with fields id, idUsername, idLicense (the last one store license that the software generate)
