• Does anyone actually use the /// comment blocks?

  - by Rachel

  Someone once said we should prefix all our methods with the /// <summary> comment blocks (C#) and I am wondering if that is true or not. I started to use them and found they annoyed me quite a bit, so stopped using them except for libraries and static methods. They're bulky and I'm always forgetting to update them. Do you recommend using them? Why? EDIT: I normally use // comments all the time, it's just the /// <summary> blocks I was wondering about

• What should be a fair amount of time in an interview before rejecting a candidate?

  - by Danish

  As a panelist for technical interviews, you often come across candidates who have all the requried educational qualifications, skill sets and experience level on resumes, but struggle to answer even the most basic questions. Ideally, technical interviews should try to check different aspects of a candidate and test them on various skills. So, if the candidate falters on one aspect, one should test the other ones before coming to a conclusion. But often, if a candidates falters on the first few questions, the red flag rises up pretty quickly. What in your opinion should be the bare minimum time spent with a candidate before making a fair accessment of his/her skills and suitability for the job?

• How to practice object oriented programming?

  - by user1620696

  I've always programmed in procedural languages and currently I'm moving towards object orientation. The main problem I've faced is that I can't see a way to practice object orientation in an effective way. I'll explain my point. When I've learned PHP and C it was pretty easy to practice: it was just matter of choosing something and thinking about an algorithm for that thing. In PHP for example, it was matter os sitting down and thinking: "well, just to practice, let me build one application with an administration area where people can add products". This was pretty easy, it was matter of thinking of an algorithm to register some user, to login the user, and to add the products. Combining these with PHP features, it was a good way to practice. Now, in object orientation we have lots of additional things. It's not just a matter of thinking about an algorithm, but analysing requirements deeper, writing use cases, figuring out class diagrams, properties and methods, setting up dependency injection and lots of things. The main point is that in the way I've been learning object orientation it seems that a good design is crucial, while in procedural languages one vague idea was enough. I'm not saying that in procedural languages we can write good software without design, just that for sake of practicing it is feasible, while in object orientation it seems not feasible to go without a good design, even for practicing. This seems to be a problem, because if each time I'm going to practice I need to figure out tons of requirements, use cases and so on, it seems to become not a good way to become better at object orientation, because this requires me to have one whole idea for an app everytime I'm going to practice. Because of that, what's a good way to practice object orientation?

• DOMDocument groupping nodes, with clone, nodeClone, importNode, fragment... What the better way?

  - by Peter Krauss

  A "DOMNodeList grouper" (groupList() function below) is a function that envelopes a set of nodes into a tag. Example: INPUT <root><b>10</b><a/><a>1</a><b>20</b><a>2</a></root> OUTPUT of groupList($dom->getElementsByTagName('a'),'G') <root><b>10</b> <G><a/><a>1</a><a>2</a></G> <b>20</b></root> There are many ways to implement it, what is the better? function groupList_v1(DOMNodeList &$list,$tag,&$dom) { $list = iterator_to_array($list); // to save itens $n = count($list); if ($n && $list[0]->nodeType==1) { $T = $dom->createDocumentFragment(); $T->appendChild($dom->createElement($tag)); for($i=0; $i<$n; $i++) { $T->firstChild->appendChild( clone $list[$i] ); if ($i) $list[$i]->parentNode->removeChild($list[$i]); } $dom->documentElement->replaceChild($T,$list[0]); }//if return $n; }//func function groupList_v2(DOMNodeList &$list,$tag,&$dom) { $list = iterator_to_array($list); // to save itens $n = count($list); if ($n && $list[0]->nodeType==1) { $T = $dom->createDocumentFragment(); $T->appendChild($dom->createElement($tag)); for($i=0; $i<$n; $i++) $T->firstChild->appendChild( clone $list[$i] ); $dom->documentElement->replaceChild($T,$list[0]); for($i=1; $i<$n; $i++) $list[$i]->parentNode->removeChild($list[$i]); }//if return $n; }//func // ...

• Inserting HTML code with jquery

  - by J. Robertson

  One of our web applications is a page that takes in a serial number and various information is returned and displayed to the user. The serial is passed via AJAX, and based on the response, one of the following can happen - An error message is shown A new form replaces the previous form Now, the way I am handling this is to use jQuery to destroy (using $.remove()) the table that displayed the initial serial form, then I'm appending another html table that contains another form. Right now I am including that additional form as part of the html source, and just setting it to display:none, then using jQuery to show it when appropriate. However, I don't like this approach because if someone views source on the page, they can see that table html code that is not being displayed. My next thought would be to use AJAX to read in another HTML file, and append it that way. However, I am trying to keep down the number of files this project uses, and since most pages in our project will use AJAX, I could see a case where there are multiple files containing HTML snippets - and that feels sloppy to me. What is the best way to handle a case where multiple html elements are being shown and removed with jQuery?

• Future of WPF and free controls ? [closed]

  - by Justin

  I am willing to work on a personal project that I would like to release publicly. I am working with Silverlight and have experience with XAML, as it is my full-time job. It is enjoyably for me to create UIs in Blend and XAML. I am also a big fan of C# language. I don't know what I would do without LINQ now. Anyways, I was looking at using WPF for my personal project. It seems that a lot of the controls out on the web are pay for items. The only place I have found to have a significant number of free controls is the WPF extended framework on codeplex. I want to make a financial application and need a powerful datagrid type of control that will allow me to enter transaction data. I haven't found such control for free in the net. It doesn't seem like there is much free community libraries/controls out there for Microsoft products. So, I was wondering if WPF would be the right way for me to go. I couldn't find any information on WPF usage in Windows 8, which coming very soon. I don't know Microsoft's plans for this technology. Would it be a better idea to use something different for the UI instead of WPF?

• Should I break contract early?

  - by cbang

  About 7 months ago I made the switch from a 5 year permie role (as a support developer in C#) to a contract role. I did this because I was stagnating in my old role. The extra cash contracting is really helping too. Unfortunately my team leader has taken a dislike to me from day 1. He regularly tells me I went out contracting too early, and frequently remarks that people in their 20's have no idea what they are talking about (I am 29). I was recently given the task of configuring our reports via our in house reporting library. It works off of a database driven criteria base, with controls being loaded as needed. The configs can get fairly complex, with controls having various levels of dependency on each other. I had a short time frame to get 50 reports working, and I was told to just get the basic configuration done, after which they will be handed over to the reporting team for fine tuning, then the test team. Our updated system was deployed 2 weeks ago, and it turned out that about 15 reports had issues causing incorrect data to be returned. Upon investigation I discovered that the reporting team hadn't even looked at them, and the test team hadn't bothered to test the reports. In spite of this, my team leader has told me that it is 100% my fault. As a result, our help desk got hit hard. I worked back until 2am that night to fix the highest priority issues (on my wedding anniversary!). The next day I arrive at work at 7:45 am to continue with the fixes. I got no thanks, but keep getting repeatedly told by my manager that "I fucked up" and "this is all my fault". I told my team leader I would spend part of my weekend working to fix the remaining issues. His response was "so you fucking should! you fucked it all up!" in front of the rest of the team. I responded "No worries." and left. I spent a decent chunk of my weekend working on it. Within 2 business days of finding out about the issues, I had all the medium and high priority issues fixed. The only comments my team leader has made to me in the last 2 weeks is to tell me how I have caused a big mess, and to tell me it was all my fault. I get this multiple times a day. If I make any jokes to anyone else in the team, I get told not to be a smartass... even though the rest of the team jokes throughout the day. Apart from that, all I get is angry looks any time I am anywhere near the guy. I don't give any response other than "alright" or silence when he starts giving me a hard time. Today we found out that the pilot release for the next stage has been pushed back. My team leader has said this was caused by me (but the higher ups said no such thing). He also said I have "no understanding of the ramifications of my actions". My question is, should I break contract (I am contracted until June 30) and find another role? No one else in my team will speak up in my favour, as they are contractors too and have no interest in rocking the boat. I could complain to my team leaders boss, but I can't see that helping, as I will still be stuck in the same team. As this is my first contract, I imagine getting the next one will be hard without a reference. I can't figure out if this guy is trying to get me fired up to provoke a confrontation (the guy loves conflict), or if he is just venting anger, or what. Copping this blame day after day is really wearing me down and making me depressed... especially since I have a wife and kid to support).

• Can One Get a Solid Programming Foundation Without Going To College/University?

  - by Daniel

  First, I have already searched the site and read all the previous "self-taught vs. college" topics. The majority of the answers defended that going to college was the best choice, for two main reasons: Going to college gives you the paper, which is essential to landing jobs, especially in tough economic times. Going to college gives you a solid programming base, teaching you the principles that will be essential regardless of the language/path you take after. Here comes my question: I am not worried about reason 1 at all, because I already have my own company (I build websites/ do affiliate marketing) and a stable financial situation, so I am pretty sure I won't need to look around for a job. I am worried about reason 2 though. That is, I want to make sure I'll have as solid a programming foundation as anyone else out there, and I am wondering if that is possible with self-learning. Suppose I take my time to study the very basics, like discrete maths, algorithm design, programming logic, computer architecture, Assembly, C programming, databases and data structures - mostly using books,online resources and lots of coding. Say I spend 1-2 years covering those basics. Do you think my foundation would be solid, or still lack in comparison to someone who went to college?

• White box testing with Google Test

  - by Daemin

  I've been trying out using GoogleTest for my C++ hobby project, and I need to test the internals of a component (hence white box testing). At my previous work we just made the test classes friends of the class being tested. But with Google Test that doesn't work as each test is given its own unique class, derived from the fixture class if specified, and friend-ness doesn't transfer to derived classes. Initially I created a test proxy class that is friends with the tested class. It contains a pointer to an instance of the tested class and provides methods for the required, but hidden, members. This worked for a simple class, but now I'm up to testing a tree class with an internal private node class, of which I need to access and mess with. I'm just wondering if anyone using the GoogleTest library has done any white box testing and if they have any hints or helpful constructs that would make this easier. Ok, I've found the FRIEND_TEST macro defined in the documentation, as well as some hints on how to test private code in the advanced guide. But apart from having a huge amount of friend declerations (i.e. one FRIEND_TEST for each test), is there an easier idion to use, or should I abandon using GoogleTest and move to a different test framework?

• Is there a variable width font that does not change width when adding effects like bold, italic?

  - by George Bailey

  NetBeans has a word wrap feature now - but if the font changes width when bold then it gets all jumpy and sometimes hard to work with. Edit: It turns out that even with Courier New that NetBeans word wrap still jumps up and down lines at a time at random. I guess that this question no longer cares for an answer. However,, it seems that there is no answer. (at least nobody has brought one up yet) I am currently using Comic Sans MS which gets wider when bold.

• Handling Indirection and keeping layers of method calls, objects, and even xml files straight

  - by Cervo

  How do you keep everything straight as you trace deeply into a piece of software through multiple method calls, object constructors, object factories, and even spring wiring. I find that 4 or 5 method calls are easy to keep in my head, but once you are going to 8 or 9 calls deep it gets hard to keep track of everything. Are there strategies for keeping everything straight? In particular, I might be looking for how to do task x, but then as I trace down (or up) I lose track of that goal, or I find multiple layers need changes, but then I lose track of which changes as I trace all the way down. Or I have tentative plans that I find out are not valid but then during the tracing I forget that the plan is invalid and try to consider the same plan all over again killing time.... Is there software that might be able to help out? grep and even eclipse can help me to do the actual tracing from a call to the definition but I'm more worried about keeping track of everything including the de-facto plan for what has to change (which might vary as you go down/up and realize the prior plan was poor). In the past I have dealt with a few big methods that you trace and pretty much can figure out what is going on within a few calls. But now there are dozens of really tiny methods, many just a single call to another method/constructor and it is hard to keep track of them all.

• I have 5 days of vouchers for MS training… help me choose? [closed]

  - by Shyatic

  I'm a Microsoft centric guy (systems engineering side) and I already know the syntax of VB, have done VBScript pretty extensively and Excel VBA stuff as well. I want to make the leap into proper programming, probably with C# because it teaches me syntax I can use for Java if I want to go that route at some point. Since I have vouchers for 5 days of programming, and I can understand logic and understand how the .NET framework works... I would love to hear ideas on which MS Courses I should take. My primary focus is to work on web applications with web services that interact and do neat stuff... like for example, to create a 'chat' room or something interactive on the web. Or should I do something with HTML5/JS? I am really not sure... like I said, I want to work to make web services/sites. Not making the next Facebook mind you, but I'd like to work towards something in that spectrum on a much smaller scale. Please give me any advice, I'd like to book these classes asap Obviously getting involved with SQL and things that I will require would be important here.. you guys know better than me! Thanks!

• Simple vs Complex (but performance efficient) solution - which one to choose and when?

  - by ManojGumber

  I have been programming for a couple of years and have often found myself at a dilemma. There are two solutions - one is simple one i.e. simple approach, easier to understand and maintain. It involves some redundancy, some extra work (extra IO, extra processing) and therefore is not the most optimal solution. but other uses a complex approach,difficult to implement, often involving interaction between lot of modules and is a performance efficient solution. Which solution should I strive for when I do not have hard performance SLA to meet and even the simple solution can meet the performance SLA? I have felt disdain among my fellow developers for simple solution. Is it good practice to come up with most optimal complex solution if your performance SLA can be met by a simple solution?

• Programming and Ubiquitous Language (DDD) in a non-English domain

  - by Sandor Drieënhuizen

  I know there are some questions already here that are closely related to this subject but none of them take Ubquitous Language as the starting point so I think that justifies this question. For those who don't know: Ubiquitous Language is the concept of defining a (both spoken and written) language that is equally used across developers and domain experts to avoid inconsistencies and miscommunication due to translation problems and misunderstanding. You will see the same terminology show up in code, conversations between any team member, functional specs and whatnot. So, what I was wondering about is how to deal with Ubiquitous Language in non-English domains. Personally, I strongly favor writing programming code in English completely, including comments but ofcourse excluding constants and resources. However, in a non-English domain, I'm forced to make a decision either to: Write code reflecting the Ubiquitous Language in the natural language of the domain. Translate the Ubiquitous Language to English and stop communicating in the natural language of the domain. Define a table that defines how the Ubiquitous Language translates to English. Here are some of my thoughts based on these options: 1) I have a strong aversion against mixed-language code, that is coding using type/member/variable names etc. that are non-English. Most programming languages 'breathe' English to a large extent and most of the technical literature, design pattern names etc. are in English as well. Therefore, in most cases there's just no way of writing code entirely in a non-English language so you end up with a mixed languages. 2) This will force the domain experts to start thinking and talking in the English equivalent of the UL, something that will probably not come naturally to them and therefore hinders communication significantly. 3) In this case, the developers communicate with the domain experts in their native language while the developers communicate with each other in English and most importantly, they write code using the English translation of the UL. I'm sure I don't want to go for the first option and I think option 3 is much better than option 2. What do you think? Am I missing other options?

• How common is prototyping as the first stage of development?

  - by EpsilonVector

  I've been taking some software design courses in the past few semesters, and while I see the benefit in a lot of the formalism, I feel like it doesn't tell me anything about the program itself: You can't tell how the program is going to operate from the Use Case spec, even though it discusses what the program can do. You can't tell anything about the user experience from the requirements document, even though it can include quality requirements. Sequence diagrams are a good description of how the software works as the call stack, but are very limited, and give a highly partial view of the overall system. Class diagrams are great for describing how the system is built, but are utterly useless in helping you figure out what the software needs to be. Where in all this formalism is the bottom line: how the program looks, operates, and what experience it gives? Doesn't it make more sense to design off of that? Isn't it better to figure out how the program should work via a prototype and strive to implement it for real? I know that I'm probably suffering from being taught engineering by theoreticians, but I need to ask, do they do this in the industry? How do people figure out what the program actually is, not what it should conform to? Do people prototype a lot, or do they mostly use the formal tools like UML and I just didn't get the hang of using them yet?

• Are there well-known PowerShell coding conventions?

  - by Tahir Hassan

  Are there any well-defined conventions when programming in PowerShell? For example, in scripts which are to be maintained long-term, do we need to: Use the real cmdlet name or alias? Specify the cmdlet parameter name in full or only partially (dir -Recurse versus dir -r) When specifying string arguments for cmdlets do you enclose them in quotes (New-Object 'System.Int32' versus New-Object System.Int32 When writing functions and filters do you specify the types of parameters? Do you write cmdlets in the (official) correct case? For keywords like BEGIN...PROCESS...END do you write them in uppercase only? It seems that MSDN lack coding conventions document for PowerShell, while such document exist for example for C#.

• Approaching Java/JVM internals

  - by spinning_plate

  I've programmed in Java for about 8 years and I know the language quite well as a developer, but my goal is to deepen my knowledge of the internals. I've taken undergraduate courses in PL design, but they were very broad academic overviews (in Scheme, IIRC). Can someone suggest a route to start delving into the details? Specifically, are there particular topics (say, garbage collection) that might be more approachable or be a good starting point? Is there a decent high-level book on the internals of the JVM and the design of the Java programming language? My current approach is going to be to start with the JVM spec and research as needed.

• Why is CSS3 doing animations?

  - by Joseph the Dreamer

  Like what the title says, why are there animations in CSS3? With basis from the "rule" of separation of concerns, HTML is the content, CSS is the style, and JavaScript is the interactive component. And by interactivity, one can conclude that anything moving due to any interaction, user or non-user triggered should be covered by JavaScript, not CSS. So why did they make CSS3 capable of doing animations? Doesn't it breach the rule, which is separation of concerns? Is there anything I missed that makes animations qualified to be classified as styles rather than interaction?

• What is a widely accepted term for a string variable that would probably contain a file path and file name?

  - by Peter Turner

  For functions that need to index files in a directory and rename them FileName0001, FileName0002, etc... I often need to write a function that splits the file name from the file path and rename the file. When I put the file name and file path back together, I don't have a very good name for the variable that contains both of them and I usually just wind up concatenating them every time I want to use them (usually using them as parameters for functions labeled either filename or filepath) so I never really know what I'm doing until I notice a lot of files being written in the same directory as my binaries. Anyway, what do I call a file name and a file path? I don't want to call it File, because that usually means the binary information behind the file. I don't want to call it URI because that usually means I've got some sort of protocol, which I don't. I just want a good way to denote "c:\somedir\somedir\somedir\somefile.txt" so as to deconfuse this mess I've just realized I'm in. Please don't just list your personal preference. I think an excellent answer should "'site its sources". (as in, provide a link to a repository with a good example of the code being used as I described)

• What are the most important concepts to understand for "fluency in developer English"?

  - by Edward Tanguay

  In April, I'm going to be giving a talk called **English 2.0 - Understanding the Language of Developers" to a group of English teachers. The purpose is in two hours to give them a quick background in key concepts so that they can better understand developer blogs and podcasts and are able to ask better questions when talking to developers. What do you think are the most important concepts to understand, concepts that developers take for granted but the general public is not familiar with? Here are a few ideas: version control abstractions pub/sub push vs. pull debugging modularity three-tier architecture class/object "spaghetti code" vs. OOP exception throwing crowd sourcing refactoring the cloud DRY - don't repeat yourself client/server unit testing designer/developer

• Books and stories on programming culture, specifically in the 80's / early 90's

  - by Ivo van der Wijk

  I've enjoyed a number of (fiction/non-fiction books) about hacker culture and running a software business in the 80's, 90's. For some reason things seemed so much more exciting back then. Examples are: Microserfs (Douglas Coupland) Accidental Empires (Robert X. Cringely Almost Pefect (W.E. Peterson, online!) Coders at Work (Peter Seibel) Today I'm an entrepeneur and programmer. Back in the 80's a I was a young geek hacking DOS TSR's and coding GWBasic / QBasic. In the 90's I was a C.S. university student, experiencing the rise of the Internet world wide. When reading these books running a software business seemed so much more fun than it is nowadays. Things used to be so much simpler, opportunities seemed to be everywhere and the startups seemed to work with much more real problems (inventing spreadsheets, writing word processors in assembly on 6 different platforms) than all our current web 2.0 social networking toys. Does anyone share these feelings? Does anyone have any good (personal) stories from back then or know of other good books to read?

• Client/Server Application Using Google App Engine

  - by Kevin Zhang

  Can someone please advise me what is the possible solution of using GAE to make a Client/Serer Application? As far as I know, GAE is designed to do web applications. What I want to do is to have a Java Client(Swing based) deployed on a number of computers and deploy the server on GAE. I found an example on GAE website which teaches how to make a SOAP service using GAE, but I don't know whether using SOAP is a good idea for client/server applications. Can someone give me some hints about how to design this system and what technology should be used? Any advices are welcome. Many thanks.

• Is defining every method/state per object in a series of UML diagrams representative of MDA in general?

  - by Max

  I am currently working on a project where we use a framework that combines code generation and ORM together with UML to develop software. Methods are added to UML classes and are generated into partial classes where "stuff happens". For example, an UML class "Content" could have the method DeleteFromFileSystem(void). Which could be implemented like this: public partial class Content { public void DeleteFromFileSystem() { File.Delete(...); } } All methods are designed like this. Everything happens in these gargantuan logic-bomb domain classes. Is this how MDA or DDD or similar usually is done? For now my impression of MDA/DDD (which this has been called by higherups) is that it severely stunts my productivity (everything must be done The Way) and that it hinders maintenance work since all logic are roped, entrenched, interspersed into the mentioned gargantuan bombs. Please refrain from interpreting this as a rant - I am merely curious if this is typical MDA or some sort of extreme MDA UPDATE Concerning the example above, in my opinion Content shouldn't handle deleting itself as such. What if we change from local storage to Amazon S3, in that case we would have to reimplement this functionality scattered over multiple places instead of one single interface which we can provide a second implementation for.

• What is Object Oriented Programming ill-suited for?

  - by Richard JP Le Guen

  In Martin Fowler's book Refactoring, Fowler speaks of how when developers learn something new, they don't consider when it's inappropriate for the job: Ten years ago it was like that with objects. If someone asked me when not to use objects, it was hard to answer. [...] It was just that I didn't know what those limitations were, although I knew what the benefits were. Reading this, it occurred to me I don't know what the limitations or potential disadvantages of Object-Oriented Programming are. What are the limitations of Object Oriented Programming? When should one look at a project and think "OOP is not best suited for this"?

• How can I select an appropriate licensing/obfuscation system for .NET?

  - by Adam

  I saw someone suggesting .NET Reactor once as a good obfuscator. I went to their website to check it out and saw they have a product called IntelliLock which is advertised as a pretty robust licensing system which has code protection/obfuscation built in. With that said, I tried to contact them and ask them a few questions regarding the product, but have not had any response. This is kind of a red flag for me. However, it seems like there is some user base for this product whom are satisfied. What .NET licensing system(s) with .NET code protection/obfuscation are you using? What are its pros & cons that you have encountered? Are there things I should be looking for or looking to avoid when evaluating these systems?
