  • How to tell whether your programmers are under-performing?

    - by A Team Lead
    I am a team lead with 5+ developers. I have a developer (let's call him A) who is a good programmer, who writes good clean, easy to understand code. However he is somewhat difficult to manage, and sometimes I wonder whether he is really under-performing or not. Our company requires the developers to indicate the work progress in the bug tracker we use, not so much as to monitor the programmers but to let the stackholders know the progress. The thing is, A only updates a task progress when it is done ( maybe 3 weeks after it is first worked on) and this leaves everyone wondering what is going on in the middle of the development week. He wouldn't change his habit despite repeated probing. ( It's OK, developers hate paperwork, I do, too) Recent 2-3 months he on leave quite often due to various events-- either he is sick, or have to attend a lot of personal events etc. ( It's OK, bad things happen in a string. It's just a coincidence) We define sprints, or roadmaps for each month. And in the beginning of the sprint, we will discuss the amount of work each of the developers have to do in a sprint and the developers get to set the amount of time they need for each task. He usually won't be able to complete all of them. (It's OK, the developers are regularly missing deadlines not due to their fault). If only one or two of the above events happen, I won't feel that A is under-performing, but they all happen together. So I have the feeling that A is under-performing and maybe-- God forbid--- slacking off. This is just a feeling based on my years of experience as programmer. But I could be wrong. It is notoriously hard to measure the work of a programmer, given that not all two tasks are alike, and there lacks a standard objective to measure the commitment of a programmer to your company. It is downright impossible to tell whether the programmer is doing his job or slacking off. All you can do, is to trust them-- yeah, trusting and giving them autonomy is the best way for programmers to work, I know that, so don't start a lecture on why you need to trust your programmers, thank you every much-- but if they abuse your trust, can you know? My question is, how can you tell whether your programmers are under-performing? Surely there are experience team leads who know better than me on this? Outcome: I've a straight talk with him regarding my perception on his performance. He was indignant when I suggested that I had the feeling that he wasn't performing at his best level. He felt that this was a completely unfair feeling. I then replied that this was my feeling and I didn't know whether my feeling was right or not. He would have none of this and ended the discussion immediately. Before he left he said that he "would try to give more to the company" in a very cold tone. I was taken aback by his reaction. I am sure that I offended him in some ways. Not too sure whether that was the right thing to do for me to be so frank with him, though. Extra notes: I hate micromanaging. So all that we have for our software process is Sprint ( where tasks get prioritized and assigned, and at the end of the month, a review of the amount of work done). Developers would require to update the tasks as they go along everyday. There is no standup meeting, or anything of the sort. Mainly because we have the freedom to work from home and everyone cherishes this freedom. Although I am the one who sets the deadline, but the developers will provide the estimate for each tasks and I will decide-- based on the estimate-- the tasks that go into a particular sprint. If they can't finish the tasks at the end of the sprint, I will push them to the next. So theoretically one can just do only 1 or 2 tasks during the whole sprint and then push the remaining 99 tasks to the next sprint and still he will be fine as long as justifies this-- in the form of daily work progress updates

  • LWJGL - OpenGL - Texture shading

    - by Trixmix
    I want to use LWJGL to create a shader that all it does is change the color of the given texture. For example I tell it to draw the letter A using a sprite sheet then I can tell the shader to draw the letter in a certain color. How would you do something like this without needed to create different colored letter sprite sheets? Task for the shader: Simply change all pixels to a certain color in the texture. Input: Color , texture. Output: it draws onto the screen the new colored texture. How do i accomplish such a thing?

  • Is Java easy decompilation a factor worth considering

    - by Sandra G
    We are considering the programming language for a desktop application with extended GUI use (tables, windows) and heavy database use. We considered Java for use however the fact that it can be decompiled back very easily into source code is holding us back. There are of course many obfuscators available however they are just that: obfuscators. The only obfuscation worth doing we got was stripping function and variables names into meaningless letters and numbers so that at least stealing code and renaming it back into something meaningful is too much work and we are 100% sure it is not reversible back in any automated way. However as it concerns to protecting internals (like password hashes or sensible variables content) we found obfuscators really lacking. Is there any way to make Java applications as hard to decode as .exe counterparts? And is it a factor to consider when deciding whether to develop in Java a desktop application?

  • JMonkey Engine (JME) load Blender scene with textures?

    - by leigero
    I am having the hardest time trying to accomplish the simplest task. I have created a floor and 4 walls (not that complicated) in Blender. I added a basic material and cloud texture so they have something to look at other than gray. When I import them into JMonkey they show up as solid white objects with no shading or depth. White silhouettes. I thought this may be a lighting issue, but I have ambient light added to the scene. I can remove that light or adjust its intensity and it has no affect on the scene. I exported all Blender files into OgreXML format, then converted them to .j3o format in JMonkey. I renamed the textures to match their corresponding mesh and this didn't do anything. Does anybody know how to create a flat object and put it into JMonkey with a texture? This sounds simple and there is absolutely no information on this. This should be step 1!

  • Web development tools/approaches?

    - by Clinton
    My day job involves a bit of programming, but I've recently been attempting some web development for personal reasons. I've got Drupal up and running and done basic things like add new content (i.e. heading and text) and add modules and themes, but I'm not sure how to approach actually designing pages. When I mucked around with webpages 15 years ago, it was just a mixture of HTML, CSS and Javascript, generally written with a text editor. Have things changed, or is this the way I'd make a Drupal page today? If it makes a difference, in my case the page's I want to design simply have static content, but I'd like them to be easily updatable.

  • Realistic planetary terrain generation with weights

    - by Programmdude
    I need terrain generation for a planet. The planet will be divided up into several hundred hexes, and I need it to be realistic and based on weights. I have dabbled in terrain generation before, but nothing like this. So I figure it would be a good idea to ask the community for answers, recommended articles or the like. By realistic, I mean not just random hexes, but continent shaped things with a few islands. More desert around the equator and more ice around the poles. I also have two weights I need to base it around: ice percentage and water percentage. That means that around XX% of the planet will need to be water. Does anyone have any advice or places to start? Generating arbitrary terrain is easy, but something a bit more "organic" like this seems rather difficult. It also needs to be seamless. Should be obvious since it's a planet, but no harm in pointing it out.

  • Liskov substitution and abstract classes / strategy pattern

    - by Kolyunya
    I'm trying to follow LSP in practical programming. And I wonder if different constructors of subclasses violate it. It would be great to hear an explanation instead of just yes/no. Thanks much! P.S. If the answer is no, how do I make different strategies with different input without violating LSP? class IStrategy { public: virtual void use() = 0; }; class FooStrategy : public IStrategy { public: FooStrategy(A a, B b) { c = /* some operations with a, b */ } virtual void use() { std::cout << c; } private: C c; }; class BarStrategy : public IStrategy { public: BarStrategy(D d, E e) { f = /* some operations with d, e */ } virtual void use() { std::cout << f; } private: F f; };

  • AdSense CPM and content topics

    - by Silver Moon
    I run a few blogs on topics like programming, linux tips and network security. I noticed the following: Till last year had only 1 blog that had posts on PHP, linux tips, network security etc. The AdSense RPM was around 1.00. Then I split the content into 3 separate blogs, one focused on web development/PHP/MySQL. second one focused on Linux/Windows how-tos and tips and third one focused on network security and related network topics. The Adsense RPM rose significantly for 2 blogs, and was 1.38 (PHP blog), 0.87 (tech tips blog) and 1.90 (network security blog). In the month of april 2013 the site on network security had the highest traffic and the Adsense income of that site was twice that of all three sites combined previously. My question is simple, does focusing on one topic lead to higher CPC/CPM?

  • LED 49-unit Quadcopter Formation Foreshadows The Robot Takeover

    - by Jason Fitzpatrick
    Perhaps there are a few more steps between 49 semi-autonomous quadcopters doing a little aerial dancing and Skynet, but we’re awed and apprehensive at the same time. Check out the video to see them in action. The video comes to us courtesy of a German art conference, Ars Electronica, and a colloboration between two design groups Futurelab and Ascending Technologies GmbH. The above video is just their warmup routine; according to YouTube comments they’ll be uploading even more videos of the quadcopters and their synchronized night flights in the coming days.

  • Force usb to use same device id, instead of new one

    - by m s kumar
    I am having some trouble in automating the task. I am testing some android based mobiles in linux machine. The automation script uses the device id under "/dev/bus/usb/001/"053" it will be always under bus 001 only.. But the dev is will be random like if i insert one mobile then the dev id will be 053, if remove and insert it again then the dev id will be 054.. The problem is, when some tests runs on the device and if device gets rebooted then new dev id is showing for the rebooted one and my scripts failing due to new dev id.. Is there any way to force usb devices to use same dev id instead of new one. So that there will be no issues to my tests even after device reboots. Thanks in advance.

  • Why would one overload the && and & operator?

    - by acidzombie24
    The same question goes for | and ||. Why would one overload or 'use' the & and && operator? The only use i thought of are Bitwise Ands for int base types (but not float/decimals) using & logical short circuit for bools/functions that return bool. Using the && operator usually. I cant think of any classes that use those operators. Absolutely none. I know a class might support + (and not '-') which combine two strings together. I seen an object such as datetime overload '-' so two dates can be subtracted to make a timespan (obviously you cant add two dates) but i never seen &, &&, | and || used. Does anyone know of a use? In any language?

  • What is a good use case for scala?

    - by Usman Ismail
    In a current project we have setup the build so that we could mix Java and Scala. I would like to use more Scala in our code base to make the code more readable and concise. In the process also learn the language by handing over real features. So I plan to use Scala for some classes to showcase its benefits and convince other devs to look into using Scala too. For a rest based web server or a program in general what kind of code structures lend themselves to Scala's functional programming style.

  • Why are most GNU's software written in C

    - by BallroomProgrammer
    I am a Java developer, and I rarely write GUI program in C. However, I noticed that many GNU's projects, such as PSPP, R, Dia, etc., are written in C, instead of Java or C++. I personally don't mind this, but I am really curious why GNU favors C so much. My understanding is that C is the one that supports the least in object-oriented programming, and today's CS education really emphasizes OOP, as OOP really makes codes more reusable. In this case, why would so many developers choose to develop in C instead of C++ or Java. Does anyone know why GNU's software are so exclusively written in C? Do you think or GNU's software should be written in C++ or Java so that the source code could be more useful to people? Why or why not?

  • Easiest solution to setup payments for a conference registration page?

    - by Keith G
    I've got a fair amount of website development experience, but I've been asked to setup a conference registration page in short order. However, I have absolutely zero experience with shopping carts, payment processing, etc. What is the absolutely quickest and easiest way to get this thing up and running? Here are my criteria: Site is currently hosted on Godaddy.com and someone has suggested using their QuickCart We cannot use any option that visits the paypal.com domain because it has been blocked my a large segment of the potential audience (on a military base). Need a $0 option for speakers Cancellations can be accepted, so maybe something that could handle that would be a bonus There is no "product" other than a confirmation that they have registered for the conference.

  • Webshop for digital goods with voucher / gift card system [duplicate]

    - by Kelzama
    This question already has an answer here: Which Ecommerce Script Should I Use? 1 answer I'm searching for a webshop which provides the following: The shop offers digital goods (like mp3) User can buy a voucher / gift card @Reseller (Or there is a code provided in the CD) User can enter his code @ webshop and gets the download (unregistered) User can enter his code @ webshop and download is added to his/her library (registered) optional: Resellers can buy codes from the Webshop I already tried prestashop as it looks quite nice. But it needs a lot of custom programming (and has a very strange voucher-system). Customer has to add the File into the basket and add the voucher at checkout. I want to skip that ;) Is there a Webshop (Or CMS + Plugin) which provides the things I need? (it could also be a CMS with a Storage/Folder Plugin (like joomla + K2) and a possibility to activate downloads via unique Codes.) Any ideas are highly appreciated :) Thanks in advance.

  • Does one's native spoken language affect quality of code?

    - by Xepoch
    There is a school of thought in linguistics that problem solving is very much tied to the syntax, semantics, grammar, and flexibility of one's own native spoken language. Working with various international development teams, I can clearly see a mental culture (if you will) in the codebase. Programming language aside, the German coding is quite different from my colleagues in India. As well, code is distinctly different in Middle America as it is in Coastal America (actually, IBM noticed this years ago). Do you notice with your international colleagues (from ANY country) that coding style and problem solving are in-line with native tongues?

  • SQL Server Management Studio won’t shutdown

If you click on Management Studio it just beebs at you. Well the problem is likely to be the help viewer, and this happens more on new installs. What happens is that the help viewer gets launched for some reason, but as a background task. However on a new install when the help viewer is launched it asks you if you want to be a surf dude or a...(read more)

  • Is true multithreading really necessary?

    - by Jonathan Graef
    So yeah, I'm creating a programming language. And the language allows multiple threads. But, all threads are synchronized with a global interpreter lock, which means only one thread is allowed to execute at a time. The only way to get the threads to switch off is to explicitly tell the current thread to wait, which allows another thread to execute. Parallel processing is of course possible by spawning multiple processes, but the variables and objects in one process cannot be accessed from another. However the language does have a fairly efficient IPC interface for communicating between processes. My question is: Would there ever be a reason to have multiple, unsynchronized threads within a single process (thus circumventing the GIL)? Why not just put thread.wait() statements in key positions in the program logic (presuming thread.wait() isn't a CPU hog, of course)? I understand that certain other languages that use a GIL have processor scheduling issues (cough Python), but they have all been resolved.

  • ASP.NET 3.5 Functions and Subroutines

    The most basic of all ASP.NET 3.5 server side scripts that I ve covered using the Visual Basic programming language is not modular in nature. This means that an ASP.NET 3.5 server will interpret the scripts in the Visual Basic file e.g Default.aspx.vb from top to bottom. In most real-world applications that use Visual Basic in ASP.NET websites however most web developers structure their programs in modules.

  • Code Smell: Inheritance Abuse

    - by dsimcha
    It's been generally accepted in the OO community that one should "favor composition over inheritance". On the other hand, inheritance does provide both polymorphism and a straightforward, terse way of delegating everything to a base class unless explicitly overridden and is therefore extremely convenient and useful. Delegation can often (though not always) be verbose and brittle. The most obvious and IMHO surest sign of inheritance abuse is violation of the Liskov Substitution Principle. What are some other signs that inheritance is The Wrong Tool for the Job even if it seems convenient?

  • How could there still not be a mysqldb module for Python 3?

    - by itsadok
    This SO question is now more than two years old. MySQL is an incredibly popular database engine, Python is an incredibly popular programming language, and Python 3 has been officially released two years ago, and was available even before that. What's more, the whole mysqldb module is just a layer translating Python's db-api to MySQL's API. It's not that big of a library. I must be missing something here. How come almost* nobody in the entire open source community has spent the (I'm guessing) two weeks it takes to port this lib? Is Python 3 that unpopular? Is the combination of python and mysql not as common as I assume? Or maybe it's just a lot harder to port mysqldb than I assume? Anyone know the inside story on this? * Now I see that this guy has done it, which takes some of the wind out of my question, but it still seems to little and too late to make sense.

  • How to explain OOP concepts to a non technical person?

    - by John
    I often try to avoid telling people I'm a programmer because most of the time I end up explaining to them what that really means. When I tell them I'm programming in Java they often ask general questions about the language and how it differs from x and y. I'm also not good at explaining things because 1) I don't have that much experience in the field and 2) I really hate explaining things to non-technical people. They say that you truly understand things once you explain them to someone else, in this case how would you explain OOP terminology and concepts to a non technical person?
