• Is looking for code examples constantly a sign of a bad developer?

  - by Newly Insecure

  I am a comp sci student with several years of experience in C and C++, and for the last few years I've been constantly working with Java/Objective C doing app dev and now I have switched to web dev and am mainly focused on ruby on rails and I came to the realization that (as with app dev, really) I reference other code wayyyy too much. I constantly google functionality for lots of things I imagine I should be able to do from scratch and it's really cracked my confidence a bit. Basic fundamentals are not an issue, I hate to use this as an example but I can run through javabat in both java/python at a sprint - obviously not an accomplishment and but what I mean to say is I have a strong base for the fundamentals I think? I know what I need to use typically but reference syntax constantly. Would love some advice and input on this, as it has been holding me back pretty solidly in terms of looking for work in this field even though I'm finishing my degree. My main reason for asking is not really about employment, but more that I don't want to be the only guy at a hackathon not hammering out nonstop code and sitting there with 20 google/github tabs open, and I have refrained from attending any due to a slight lack of confidence... Is a person a bad developer by constantly looking to code examples for moderate to complex tasks?

• tips, guidelines, points to remember for rendering professional code?

  - by ronnieaka

  I'm talking about giving clients professional looking code. The whole nine yards, everything you hardcore professional highly experienced programmers here probably do when coding freelance or for the company you work in. I'm fresh out of college and I'm going into freelance. I just want to be sure that my first few projects leave a good after-taste of professionalism imprinted on the clients' minds. When I Googled what i'm asking here, I was given pages that showed various websites and tools that let you make flashy websites and templates etc. The $N package and such stuff. I can't recall the word experts use for it. Standard, framework [i know that's not it]. English isn't my first language so I'm sorry I don't really don't know the exact phrase for it. That abstract way of writing code so that you don't come across as a sloppy programmer. That above mentioned way for programming websites and desktop software [in python/C/C++/Java]. EDIT: i can work on the accruing vast knowledge and know-how and logic building etc. what i'm asking for is the programming standard/guidelines you guys follow so that the client on seeing code feels that its a professional solution. Like comment blocks, a particular indentation style something like that. Is there any book on it or specific list of points for enterprise type coding by them? Especially here as in my case, for building websites [php for now..], and desktop software [c/c++/java/python]

• Should we hire a new developer now, or wait until the code is refactored to make it suitable for a team environment?

  - by w0051977

  I support and develop a large system that uses various technologies e.g. c++,.net,vb6 etc. I am a sole developer. I am debating whether now is the right time to approach my manager (who is not a developer) to ask if another developer can be recruited. I don't have any experience working in software teams. I have always been a sole developer. The concerns I have are: There is still a lot to do. Training another developer would take time and distract me from my duties. The company does not invest heavily in tools e.g. source control The code in this system needs to be refactored to introduce concepts such as interfaces, polymorphism etc, which are supported by methodologies such as Agile (I inherited the system about 12 months ago). I am gradually trying to refactor the code. I believe I have two options: Approach my manager now Wait until I have had time to refactor the code so it is more suitable for a team environment. Which option is best? I am hoping to hear from other developers who have been in my situation.

• PHP Code (modules) included via MySQL database, good idea?

  - by ionFish

  The main script includes "modules" which add functionality to it. Each module is set up like this: <?php //data collection stuff //(...) approx 80 lines of code //end data collection $var1 = 'some data'; $var2 = 'more data'; $var3 = 'other data'; ?> Each module has the same exact variables, just the data collection is different. I was wondering if it's a reasonable idea to store the module data in MySQL like this: [database] |_modules |_name |_function (the raw PHP data from above) |_description |_author |_update-url |_version |_enabled ...and then include the PHP-data from the database and execute it? Something like, a tab-navigation system at the top of the page for each module name, then inside each of those tabs the page content would function by parsing the database-stored code of the module from the function section. The purpose would be to save code space (fewer lines), allow for easy updates, and include/exclude modules based on the enabled option. This is how many other web-apps work, some of my own too. But never had I thought about this so deeply. Are there any drawbacks or security risks to this?

• How can I better manage far-reaching changes in my code?

  - by neuviemeporte

  In my work (writing scientific software in C++), I often get asked by the people who use the software to get their work done to add some functionality or change the way things are done and organized right now. Most of the time this is just a matter of adding a new class or a function and applying some glue to do the job, but from time to time, a seemingly simple change turns out to have far-reaching consequences that require me to redesign a substantial amount of existing code, which takes a lot of time and effort, and is difficult to evaluate in terms of time required. I don't think it has as much to do with inter-dependence of modules, as with changing requirements (admittedly, on a smaller scale). To provide an example, I was thinking about the recently-added multi-user functionality in Android. I don't know whether they planned to introduce it from the very beginning, but assuming they didn't, it seems hard to predict all the areas that will be affected by the change (apps preferences, themes, need to store account info somehow, etc...?), even though the concept seems simple enough, and the code is well-organized. How do you deal with such situations? Do you just jump in to code and then sort out the cruft later like I do? Or do you do a detailed analysis beforehand of what will be affected, what needs to be updated and how, and what has to be rewritten? If so, what tools (if any) and approaches do you use?

• How to fix legacy code that uses <string.h> unsafely?

  - by Snowbody

  We've got a bunch of legacy code, written in straight C (some of which is K&R!), which for many, many years has been compiled using Visual C 6.0 (circa 1998) on an XP machine. We realize this is unsustainable, and we're trying to move it to a modern compiler. Political issues have said that the most recent compiler allowed is VC++ 2005. When compiling the project, there are many warnings about the unsafe string manipulation functions used (sprintf(), strcpy(), etc). Reviewing some of these places shows that the code is indeed unsafe; it does not check for buffer overflows. The compiler warning recommends that we move to using sprintf_s(), strcpy_s(), etc. However, these are Microsoft-created (and proprietary) functions and aren't available on (say) gcc (although we're primarily a Windows shop we do have some clients on various flavors of *NIX) How ought we to proceed? I don't want to roll our own string libraries. I only want to go over the code once. I'd rather not switch to C++ if we can help it.

• I can write code...but can't design well. Any suggestions?

  - by user396089

  I feel that I am good at writing code in bits and pieces, but my designs really suck. The question is how do I improve my designs (in order to become a better designer). I think schools and colleges do a good job of teaching people as to how to become good at mathematical problem solving, but lets admit the fact that most programs taught at school are generally around 1000 - 2000 lines long, which means that it is mostly an academic exercise and no way reflects the complexity of real world software (a few hundred thousand to millions of lines of code). This is where I believe that even projects like topcoder/project euler also won't be of much help, they might sharpen your mathematical problem solving ability - but you might become a theoretician programmer; someone who is more interested in the nice, clean stuff, and someone who is utterly un-interested in the day to day mundane and hairy stuff that most application programmers deal with. So my question is how do I improve my design skills? That is the ability to design small/medium scale applications that will go into a few thousand of lines of code? How can I learn design skills that would help me build a better html editor kit, or some graphics program like gimp?

• How to convert between Enums where values share the same names ?

  - by Ross Watson

  Hi, if I want to convert between two Enum types, the values of which, I hope, have the same names, is there a neat way, or do I have to do it like this...? enum colours_a { red, blue, green } enum colours_b { yellow, red, blue, green } static void Main(string[] args) { colours_a a = colours_a.red; colours_b b; //b = a; b = (colours_b)Enum.Parse(typeof(colours_b), a.ToString()); } Thanks, Ross

• How can I compile some parts of C++/CLI code as Native and some part as Managed?

  - by Usman

  Hello, I am calling LoadTypeLib for loading unmanaged type libraries in C++/CLI. I need to compile some code(some code areas) as managed and some code areas as unmanaged(native) code and form a mixed mode class library as executable. What i need to mention between the lines of code so that whatever the part i need to be compiled as managed should compiled as managed and what part I need to be unmanaged(native) should be compiled as native?

• Any software for pattern-matching and -rewriting source code?

  - by Steven A. Lowe

  I have some old software (in a language that's not dead but is dead to me ;-)) that implements a basic pattern-matching and -rewriting system for source code. I am considering resurrecting this code, translating it into a modern language, and open-sourcing the project as a refactoring power-tool. Before I go much further, I want to know if anything like this exists already (my google-fu is fanning air on this tonight). Here's how it works: the pattern-matching part matches source-code patterns spanning multiple lines of code using a template with binding variables, the pattern-rewriting part uses a template to rewrite the matched code, inserting the contents of the bound variables from the matching template matching and rewriting templates are associated (1:1) by a simple (unconditional) rewrite rule the software operates on the abstract syntax tree (AST) of the input application, and outputs a modified AST which can then be regenerated into new source code for example, suppose we find a bunch of while-loops that really should be for-loops. The following template will match the while-loop pattern: Template oldLoopPtrn int @cnt@ = 0; while (@cnt@ < @max@) { … @body@ ++@cnt@; } End_Template while the following template will specify the output rewrite pattern: Template newLoopPtrn for(int @cnt@ = 0; @cnt@ < @max@; @cnt@++) { @body@ } End_Template and a simple rule to associate them Rule oldLoopPtrn --> newLoopPtrn so code that looks like this int i=0; while(i<arrlen) { printf("element %d: %f\n",i,arr[i]); ++i; } gets automatically rewritten to look like this for(int i = 0; i < arrlen; i++) { printf("element %d: %f\n",i,arr[i]); } The closest thing I've seen like this is some of the code-refactoring tools, but they seem to be geared towards interactive rewriting of selected snippets, not wholesale automated changes. I believe that this kind of tool could supercharge refactoring, and would work on multiple languages (even HTML/CSS). I also believe that converting and polishing the code base would be a huge project that I simply cannot do alone in any reasonable amount of time. So, anything like this out there already? If not, any obvious features (besides rewrite-rule conditions) to consider? EDIT: The one feature of this system that I like very much is that the template patterns are fairly obvious and easy to read because they're written in the same language as the target source code, not in some esoteric mutated regex/BNF format.

• How to get short month names in Joda Time?

  - by Mr Morgan

  Hello Does anyone know if there's a method in Joda Time or Java itself which takes either an int or a String as an argument, e.g. 4 or "4" and gives the name of the month back in short format, i.e. JAN for January? I suppose long month names can be truncated and converted to upper case. Thanks Mr Morgan.

• How to precompile WCF code and then host it on IIS ?

  How do you precompile WCF code so that the WCF code can't be seen by anyone who has access to the WCF code. it's possible to this with ASP.NET code by using the "precompilation" feature. basically, what the precompilation feature does is enable the developper to deploy "binaries" to IIS instead of a folder containing source code. can this be done with WCF too ?

• What is the naming convention in Python for variable and function names?

Windows is x million lines of code. Question: When is "#lines of code" useful? ps: Note that when such statements are made, the tone is "more is better".
