• How to stop gold-plating and just be content to release working developments

  - by Andy Bowskill

  The development team that I'm a member of has recently adapted to work according to Agile practices. This has personally highlighted the fact that I can't stop myself gold-plating code (and documentation) and I consequently exceed original estimates, when I could've delivered solutions that meet the requirements much earlier. I think my ethic is bordering on the obsessive in that I become too attached to my code and am rarely content to release before I've refactored and perfected it to the nth degree. I am happy that I have realised this but how can I change my attitude/mentality to be content with my progress and release on-time instead?

• I'm having trouble understanding these exercises wording.

  - by KasHKoW

  Exercise 1-20. Write a program detab that replaces tabs in the input with the proper number of blanks to space to the next tab stop. Assume a fixed set of tab stops, say every n columns. Should n be a variable or a symbolic parameter? Exercise 1-21. Write a program entab that replaces strings of blanks by the minimum number of tabs and blanks to achieve the same spacing. Use the same tab stops as for detab. When either a tab or a single blank would suffice to reach a tab stop, which should be given preference? could you paraphrase these for me. thanks

• Picking Core Language For Large Scale Web Platform

  - by ryanzec

  Now I have work with PHP and ASP.NET quite a bit and also played around few other language for web development. I am now at a point where need to start building a backend platform that will have the ability to support a large set of applications and I am trying to figure out which language I want to choose as my core language. When I say core language I mean the language that the majority of the backend code is going to be in. This is not to say that other languages won't be used because my guess is that they will but I want a large majority of the code (90%-98%) to be in 1 language. While I see to benefit of using the language that is best for the job, having 15% in php, 15% in ASP.NET, 5% in perl, 10% in python, 15% in ruby, etc… seems like a very bad idea to me (not to mention integrating everything seamlessly would probably add a bit of overhead). If you were going to be building a large scale web platform that need to support multiple applications from scratch, what would you choose as your core language and why?

• What Pattern will solve this - fetching dependent record from database

  - by tunmise fasipe

  I have these classes class Match { int MatchID, int TeamID, //used to reference Team ... other fields } Note: Match actually have 2 teams which means 2 TeamID class Team { int TeamID, string TeamName } In my view I need to display List<Match> showing the TeamName. So I added another field class Match { int MatchID, int TeamID, //used to reference Team ... other fields string TeamName; } I can now do Match m = getMatch(id); m.TeamName = getTeamName(m.TeamId); //get name from database But for a List<Match>, getTeamName(TeamId) will go to the database to fetch TeamName for each TeamID. For a page of 10 Matches per page, that could be (10x2Teams)=20 trip to database. To avoid this, I had the idea of loading everything once, store it in memory and only lookup the TeamName in memory. This made me have a rethink that what if the records are 5000 or more. What pattern is used to solve this and how?

• How do I detect when my system wakes up from suspend via DBus or similar in a python app?

  - by con-f-use

  In a background Python script I need to detect, when the system just woke up from suspend. What is a good way that does not rely on a root script but rather on python modules such as DBus? I'm new to dbus so I could really use some example code. From what I read it's related to org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.Resuming Can anyone help me out with some code that connects the resuming signal to callback?

• how to detect keylogger in windows that hooked up key-press?

  - by saber tabatabaee yazdi

  For security reasons we have to detect all key-loggers and log them in somewhere like windows events. I have piece of C# code that it is very easy to install all clients and up and running every day in system trays and no one can close it. We want to modify that code and send logs to central web service in our network (that this also web service is installed last year and receive and log all another security logs).

• When should one use "out" parameters?

  - by qegal

  In Objective-C, there are several methods like initWithContentsOfFile:encoding:error: where one passes in a reference to an NSError object for the error: parameter. In this example, the value of the NSError object passed in can change based on what goes on at runtime when the method is being called and whether the body of the method was executed in a certain way successfully. In a way I think of this NSError object as sort of like a second return value from the method, and only differs from an object anObject in the statement return anObject; in that when this statement is called, execution leaves the method. So my question is, not only in the context of error handling in Objective-C, but in general, when should one use an "out" parameter in place of returning said value in a return statement?

• Would you want a language to support something like "Retry/Fix"?

  - by Aaron Anodide

  I was just wondering if a language could support something like a Retry/Fix block? The answer to this question is probably the reason it's a bad idea or equivalent to something else, but the idea keeps popping into my head. void F() { try { G(); } fix(WrongNumber wn, out int x) { x = 1; } } void G() { int x = 0; retry<int> { if(x != 1) throw new WrongNumber(x); } } After the fix block ran, the retry block would run again...

• How to choose a language, when taking in account the community it includes?

  - by Rick Rhodes

  I was reading the following article: Great Hackers The following part grabbed my attention: "When you choose a language, you're also choosing a community. The programmers you'll be able to hire to work on a Java project won't be as smart as the ones you could get to work on a project written in Python. And the quality of your hackers probably matters more than the language you choose. Though, frankly, the fact that good hackers prefer Python to Java should tell you something about the relative merits of those languages." I would like to apply his advice on a commercial web application I am building (I am a strong believer in culture and community), yet this article was written in 2004, and python has increased in popularity in the recent years. How can I decided a language when taking in consideration its community, rather than the popularity? Any recommendations? Is there any language community that show dedication and passion for developing, rather than learning a language to get a Job and a paycheck?

• Is there such a thing as having too many private functions/methods?

  - by shovonr

  I understand the importance of well documented code. But I also understand the importance of self-documenting code. The easier it is to visually read a particular function, the faster we can move on during software maintenance. With that said, I like to separate big functions into other smaller ones. But I do so to a point where a class can have upwards of five of them just to serve one public method. Now multiply five private methods by five public ones, and you get around twenty-five hidden methods that are probably going to be called only once by those public ones. Sure, it's now easier to read those public methods, but I can't help but think that having too many functions is bad practice.

• Entry level engineer question regarding memory mangement

  - by Ealianis

  It has been a few months since I started my position as an entry level software developer. Now that I am past some learning curves (e.g. the language, jargon, syntax of VB and C#) I'm starting to focus on more esoteric topics, as to write better software. A simple question I presented to a fellow coworker was responded with "I'm focusing on the wrong things." While I respect this coworker I do disagree that this is a "wrong thing" to focus upon. Here was the code (in VB) and followed by the question. Note: The Function GenerateAlert() returns an integer. Dim alertID as Integer = GenerateAlert() _errorDictionary.Add(argErrorID, NewErrorInfo(Now(), alertID)) vs... _errorDictionary.Add(argErrorID, New ErrorInfo(Now(), GenerateAlert())) I originally wrote the ladder and rewrote it with the "Dim alertID" so that someone else might find it easier to read. But here was my concern and question. "Should one write this with the Dim AlertID, it would in fact take up more memory; finite but more, and should this method be called many times could it lead to an issue? How will .NET handle this object AlertID. Outside of .NET should one manually dispose of the object after use (near the end of the sub)." I want to ensure I become a knowledgeable programmer that does not just rely upon garbage collection. Am I over thinking this? Am I focusing on the wrong things?

• Cloud Computing - just get started already!

  - by BuckWoody

  OK - you've been hearing about "cloud" (I really dislike that term, but whatever) for over two years. You've equated it with just throwing some VM's in some vendor's datacenter - which is certainly part of it, but not the whole story. There's a whole world of - wait for it - *coding* out there that you should be working on. If you're a developer, this is just a set of servers with operating systems and the runtime layer (like.NET, Java, PHP, etc.) that you can deploy code to and have it run. It can expand in a horizontal way, allowing massive - and I really, honestly mean massive, not just marketing talk kind of scale. We see this every day. If you're not a developer, well, now's the time to learn. Explore a little. Try it. We'll help you. There's a free conference you can attend in November, and you can sign up for it now. It's all on-line, and the tools you need to code are free. Put down Facebook and Twitter for a minute - go sign up. Learn. Do. :) See you there. http://www.windowsazureconf.net/

• What are the benefits vs costs of comment annotation in PHP?

  - by Patrick

  I have just started working with symfony2 and have run across comment annotations. Although comment annotation is not an inherent part of PHP, symfony2 adds support for this feature. My understanding of commenting is that it should make the code more intelligible to the human. The computer shouldn't care what is in comments. What benefits come from doing this type of annotation versus just putting a command in the normal PHP code? ie- /** * @Route("/{id}") * @Method("GET") * @ParamConverter("post", class="SensioBlogBundle:Post") * @Template("SensioBlogBundle:Annot:post.html.twig", vars={"post"}) * @Cache(smaxage="15") */ public function showAction(Post $post) { }

• Non-trivial functions that operate on any monad

  - by Strilanc

  I'm looking for examples of interesting methods that take an arbitrary monad and do something useful with it. Monads are extremely general, so methods that operate on monads are widely applicable. On the other hand, methods I know of that can apply to any monad tend to be... really, really trivial. Barely worth extracting into a function. Here's a really boring example: joinTwice. It just flattens an m m m t into an m t: join n = n >>= id joinTwice n = (join . join) n main = print (joinTwice [[[1],[2, 3]], [[4]]]) -- prints [1,2,3,4] The only non-trivial method for monads that I know of is bindFold (see my answer below). Are there more?

• Immutable design with an ORM: How are sessions managed?

  - by Programmin Tool

  If I were to make a site with a mutable language like C# and use NHibernate, I would normally approach sessions with the idea of making them as create only when needed and dispose at request end. This has helped with keeping a session for multiple transactions by a user but keep it from staying open too long where the state might be corrupted. In an immutable system, like F#, I would think I shouldn't do this because it supposes that a single session could be updated constantly by any number of inserts/updates/deletes/ect... I'm not against the "using" solution since I would think that connecting pooling will help cut down on the cost of connecting every time, but I don't know if all database systems do connection pooling. It just seems like there should be a better way that doesn't compromise the immutability goal. Should I just do a simple "using" block per transaction or is there a better pattern for this?

• What is a good way to test demand for a new game platform?

  - by user15256

  I'm working on a game platform that turns your iPhone, android or iPad into a steering wheel, for racing games (like need for speed and dirt 3) and flight simulators for example. I'd love to figure out smart ways to figure out whether gamers would like something like this. I originally asked this question over on the gaming SE and it was for getflypad.com. A lot of the tech is built and most of it is doable - the question here is how to test demand and know whether gamers actually want this.

• Should I concentrate on writing code for money or my studies while in college?

  - by A-Cube

  I am college student of Software Engineering. My worries are that while I am concentrating on my studies, my peers are getting down with the code (e.g. HTML, ASP, PHP, etc) to earn money. Should I be worried that I am not doing coding like them? I was asked to be Microsoft Student Partner but I refused because the person what was doing before me told it was just arranging events. Nothing as such like getting with Microsoft and coding. Should I be writing code and earning money as I still am in 4th semester? I only have C++ as learning language in college. Will my job count on these projects that I do, or should I concentrate on studies for now to get maximum benefit?

• Is it bad practise to call a controller action from a view that was rendered by another controller?

  - by marco-fiset

  Let's say I have an OrderController which handles orders. The user adds products to it through the view, and then the final price gets calculated through an AJAX call to a controller action. The price calculation logic is implemented in a seperate class and used in a controller action. What happens is that I have many views from different controllers that need to use that particular action. I'd like to have some kind of a PriceController that I could call an action on. But then the view would have to know about that PriceController and call an action on it. Is it bad practice for a view to call an action on a different controller from which it was rendered?

• Which parallel pattern to use?

  - by Wim Van Houts

  I need to write a server application that fetches mails from different mail servers/mailboxes and then needs to process/analyze these mails. Traditionally, I would do this multi-threaded, launching a thread for fetching mails (or maybe one per mailbox) and then process the mails. We are moving more and more to servers where we have 8+ cores, so I would like to make use of these cores as much as possible (and not use 1 at 100% and leave the seven others untouched). So conceptually, as an example, it would be nice that I could write the application in such a way that two cores are "continuously" fetching emails and four cores are "continuously" processing/analyzing the emails (since processing and analyzing mails is more CPU intensive than fetching mails). This seems like a good concept, but after studying some parallel patterns, I'm not really sure how this is best implemented. None of the patterns really fit. I'm working in VS2012, native C++, but I guess from a design point of view this does not really matter and just some pointers on how to organize this would be great!

• Is deserializing complex objects instead of creating them a good idea, in test setup?

  - by Chris Bye

  I'm writing tests for a component that takes very complex objects as input. These tests are mixes of tests against already existing components, and test-first tests for new features. Instead of re-creating my input objects (this would be a large chunk of code) or reading one from our data store, I had the thought to serialize a live instance of one of these objects, and just deserialize it into test setup. I can't decide if this is a reasonable idea that will save effort in long run, or whether it's the worst idea that I've ever had, causing those that will maintain this code will hunt me down as soon as they read it. Is deserialization of inputs a valid means of test setup in some cases? To give a sense of scale of what I'm dealing with, the size of serialization output for one of these input objects is 93KB. Obtained by, in C#: new BinaryFormatter().Serialize((Stream)fileStream, myObject);

• Why do i keep forgetting things? [closed]

  - by Mr.Anubis

  I am currently learning many things at the same time in C++ and coded many data structures and algorithms and some small applications. When I suddenly try to remember something that I coded many months ago, my mind completely goes blank. It's like I'll have to re-learn the whole thing. For example, recently I was thinking to refactor my BST data structure, when I realized that I don't even remember how I coded it or how does it works internally. Does this happen with many others? Or is it me only? How do I overcome this problem?

• How do you keep track of the authors of code?

  - by dustyprogrammer

  This is something I was never taught. I have seen alot of different types of authoring styles. I code primarily in Java and Python. I was wondering if there was a standard authoring style or if everything is freestyle. Also if you answer would you mind attaching the style you use to author files that your create at home or at work. I usually just go @author garbagecollector @company garbage inc.

• What is the annoying/lacking feature in C#, in your opinion?

  - by Vimvq1987

  To be honest, I'm working with C# everyday, and I can say that I love its elegant syntax. But no language is perfect, so does C#. In my opinion, these two features are missing: Full-featured enum. I was pretty happy with enum in C#, until I know about enum in Java. Of course, we can "simulate" a full-featured enum in C# by class, but it's much better if Microsoft simplify this. Immutable keyword. We are told to let a class/struct immutable whenever possible. But to do that, we have to add readonly keyword to every field, and then if we add setter by a mistake, our class will be mutable, and nobody knows. By immutable keyword, every field will be automatically readonly, and any setter will be prohibited (error when compile). It's like static keyword added to class in C# 2.0 well. what's is your annoying/lacking feature in C#?

• How Is there anyway to Compile Notepad++?

  - by user44179

  I really like using Notepad++ to write HTML and such. After I started using Ubuntu I looked around for an alternative to Notpad++. I found a thread which lead me to try Geany and a few others, but I really miss Notepad++. Is there anyway I could compile it from the source code to use on Ubuntu? I know its written in C++. Could I just open it in Code::Blocks and compile it? You can get the source here. I wouldn't mind hearing about other alternatives, but really want to know if compiling it is possible. Thanks
