  • Good fix vs Quick fix [duplicate]

    - by Andrea Girardi
    This question already has an answer here: Does craftsmanship pay off? [duplicate] 16 answers Good design: How much hackyness is acceptable? [duplicate] 9 answers How do you balance between “do it right” and “do it ASAP” in your daily work? 14 answers Let's start from this principle: quality is a feature that you can't add to a project in the middle of the development process. This is the scenario: two weeks to go live with my project and, one of the developers added a specific method used only for one web application to our framework (Our framework is a bounce of java classes used to extract content from MongoDB, Alfresco, mySql and it's used by web applications). I'm the team leader and I told him to generalize the method to keep the framework to keep reusable but he said "no, I prefer don't do that because there are a lot of bugs that need to be fixed". The manager is agree with him and of course I'm not. Is it better to made extra effort to keep a framework free from any specific implementation (probably used only by one web application) or just add the methods because it works? So, my question is: is it correct to write code that only works or is better to write code that works but it doesn't sucks (i.e. adding embedded value, specific methods, extra classes, add column to database, etc)? How is it possible to justify the extra time (to be honest, this kind of fix requires 10 minutes extra to write a good generic code) to the management? How is possible to argue it's the right way to write code to young developers and PM? in general, good fix or quick fix? Ah, 10 minutes after I get the email from PM, he asked me why on a url of application 2 there was the name of application 1 during the login? I like to quote Jeff Atwood: "Don't leave "broken windows" (bad designs, wrong decisions, or poor code) unrepaired. Fix each one as soon as it is discovered. " Excerpt From: Hyperink. "How-To-Stop-Sucking-And-Be-Awesome-Instead." iBooks.

  • A project idea for project ideas!?

    - by Auxiliary
    First take a look at this question which I asked a few months ago. I still can't find a place where programmers and computer specialists can discuss their projects and ideas. I found OpenHatch.com. It's good but not sufficient, it's only for open-source projects and is not really a place to discuss ideas. OK, so here's an idea, Why don't we make one? The question is do you think there is a need for such a social programmer's lounge? A place where they can discuss their ideas? Do you think it's worth the time and money to start such a website? Do you think it has the potential of getting enough traffic to keep it alive? Many thanks

  • How to train yourself to avoid writing “clever” code?

    - by Dan Abramov
    Do you know that feeling when you just need to show off that new trick with Expressions or generalize three different procedures? This does not have to be on Architecture Astronaut scale and in fact may be helpful but I can't help but notice someone else would implement the same class or package in a more clear, straightforward (and sometimes boring) manner. I noticed I often design programs by oversolving the problem, sometimes deliberately and sometimes out of boredom. In either case, I usually honestly believe my solution is crystal clear and elegant, until I see evidence to the contrary but it's usually too late. There is also a part of me that prefers undocumented assumptions to code duplication, and cleverness to simplicity. What can I do to resist the urge to write “cleverish” code and when should the bell ring that I am Doing It Wrong? The problem is getting even more pushing as I'm now working with a team of experienced developers, and sometimes my attempts at writing smart code seem foolish even to myself after time dispels the illusion of elegance.

  • How common are "bandage" fixes?

    - by gablin
    Imagine the following scenario: You've detected that your (or someone else's) program has a bug - a function produces the wrong result when given a particular input. You examine the code and can't find anything wrong: it just seem to bog out when given this input. You can now do one of two things: you either examine the code further until you've found the actual cause; or you slap on a bandage by adding an if statement checking if the input is this particular input - if it is, return the expected value. To me, applying the bandage would be completely unacceptable. If the code is behaving unexpectingly on this input, what other input that you've missed will it react strangely to? It just doesn't seem like a fix at all - you're just shoveling the problem under the rug. As I wouldn't even consider doing this, I'm surprised at how often the professors and books keep reminding us about how applying "bandage" fixes is not a good idea. So this makes me wonder: just how common are these kinds of "fixes"?

  • How would i down-sample a .wav file then reconstruct it using nyquist? - in matlab [closed]

    - by martin
    This is all done in MatLab 2010 My objective is to show the results of: undersampling, nyquist rate/ oversampling First i need to downsample the .wav file to get an incomplete/ or impartial data stream that i can then reconstuct. Heres the flow chart of what im going to be doing So the flow is analog signal - sampling analog filter - ADC - resample down - resample up - DAC - reconstruction analog filter what needs to be achieved: F= Frequency F(Hz=1/s) E.x. 100Hz = 1000 (Cyc/sec) F(s)= 1/(2f) Example problem: 1000 hz = Highest frequency 1/2(1000hz) = 1/2000 = 5x10(-3) sec/cyc or a sampling rate of 5ms This is my first signal processing project using matlab. what i have so far. % Fs = frequency sampled (44100hz or the sampling frequency of a cd) [test,fs]=wavread('test.wav'); % loads the .wav file left=test(:,1); % Plot of the .wav signal time vs. strength time=(1/44100)*length(left); t=linspace(0,time,length(left)); plot(t,left) xlabel('time (sec)'); ylabel('relative signal strength') **%this is were i would need to sample it at the different frequecys (both above and below and at) nyquist frequency.*I think.*** soundsc(left,fs) % shows the resaultant audio file , which is the same as original ( only at or above nyquist frequency however) Can anyone tell me how to make it better, and how to do the various sampling at different frequencies?

  • OpenGL ES 2.0: Using VBOs?

    - by Bunkai.Satori
    OpenGL VBOs (vertex buffer objects) have been developed to improve performance of OpenGL (OpenGL ES 2.0 in my case). The logic is that with the help of VBOs, the data does not need to be copied from client memory to graphics card on per frame basis. However, as I see it, the game scene changes continuously: position of objects change, their scaling and rotating change, they get animated, they explode, they get spawn or disappear. In such highly dynamic environment, such as computer game scene is, what is the point of using VBOs, if the VBOs would need to be constructed on per-frame basis anyway? Can you please help me to understand how to practically take beneif of VBOs in computer games? Can there be more vertex based VBOs (say one per one object) or there must be always exactly only one VBO present for each draw cycle?

  • MBA versus MSIS

    - by user794684
    I am considering going back to school for my masters and I've been looking at several avenues I can take. I've been considering either an MBA or an MSIS degree. Overall I know that an MBA is going to give me a solid skill set that can help me become an executive. However they seem to be a dime a dozen these days and the University I can get into is good, but it's not exactly in the top 100 anything. My undergrad MINOR was in Business Information Systems. I'm rusty as hell, considering I haven't touched it, but an MSIS would be more in the direction of my past academic experience and seems to touch both on business management and IT. Question... With an MSIS will I just be a middleman? Will I really be an important person with a real skill set or will I merely be someone who isn't quite cut out to be a manager and who is clueless about the tech side? Is an MSIS degree going to give me a real chance to move up the pay scale quickly or am I better off learning programing, networking through another BS degree? What will give me more upward mobility career wise? An MBA or an MSIS?

  • Where do we put "asking the world" code when we separate computation from side effects?

    - by Alexey
    According to Command-Query Separation principle, as well as Thinking in Data and DDD with Clojure presentations one should separate side effects (modifying the world) from computations and decisions, so that it would be easier to understand and test both parts. This leaves an unanswered question: where relatively to the boundary should we put "asking the world"? On the one hand, requesting data from external systems (like database, extental services' APIs etc) is not referentially transparent and thus should not sit together with pure computational and decision making code. On the other hand, it's problematic, or maybe impossible to tease them apart from computational part and pass it as an argument as because we may not know in advance which data we may need to request.

  • Code Review tools - to use or not?

    - by liortal
    On my dev team, we're doing code reviews, however not in a proper way i believe. The issues our process suffers from: Not enough time is allocated for proper code review. Doing reviews is not mandatory - many times it is simply not done. Devs sit together for reviews, due to lack of another easy mechanism for doing it "offline" without spending both developers' time. My question is: can integration of a tool for code reviews improve the points mentioned above? Is it not needed? I would love to hear from positive/negative experiences.

  • OpenGL ES 2.0: Vertex and Fragment Shader for 2D with Transparency

    - by Bunkai.Satori
    Could I knindly ask for correct examples of OpenGL ES 2.0 Vertex and Fragment shader for displaying 2D textured sprites with transparency? I have fairly simple shaders that display textured polygon pairs but transparency is not applied despite: texture map contains transparency information Blending is enabled: glEnable(GL_BLEND); glEnable(GL_DEPTH_TEST); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); My Vertex Shader: uniform mat4 uOrthoProjection; uniform vec3 Translation; attribute vec4 Position; attribute vec2 TextureCoord; varying vec2 TextureCoordOut; void main() { gl_Position = uOrthoProjection * (Position + vec4(Translation, 0)); TextureCoordOut = TextureCoord; } My Fragment Shader: varying mediump vec2 TextureCoordOut; uniform sampler2D Sampler; void main() { gl_FragColor = texture2D(Sampler, TextureCoordOut); }

  • How do I set up pairing email addresses?

    - by James A. Rosen
    Our team uses the Ruby gem hitch to manage pairing. You set it up with a group email address (e.g. [email protected]) and then tell it who is pairing: $ hitch james tiffany Hitch then sets your Git author configuration so that our commits look like commit 629dbd4739eaa91a720dd432c7a8e6e1a511cb2d Author: James and Tiffany <[email protected]> Date: Thu Oct 31 13:59:05 2013 -0700 Unfortunately, we've only been able to come up with two options: [email protected] doesn't exist. The downside is that if Travis CI tries to notify us that we broke the build, we don't see it. [email protected] does exist and forwards to all the developers. Now the downside is that everyone gets spammed with every broken build by every pair. We have too many possible pair to do any of the following: set up actual [email protected] email addresses or groups (n^2 email addresses) set up forwarding rules for [email protected] (n^2 forwarding rules) set up forwarding rules for [email protected] (n forwarding rules for each of n developers) Does anyone have a system that works for them?

  • Event system architecture for networking when performance is concerned

    - by Vandell
    How should I design a system for an action game (think in Golden Axe) where events can happen remotely? I'm using TCP for this because the client is in flash. There's so many options, I can make a binary protocol (I don't like this idea, I found it to be too hard to mantain) but I was also thinking that passing jsons through clients and server can be slow (Is that a exaggerated concern?). What about the internal architecture for the server? And for the client? I'm really lost, If it's a question that is too big, please indicate me some material so I can formulate a better question next time.

  • Jack of all trades, master of none [closed]

    - by Rope
    I've got a question similar to this one: Is looking for code examples constantly a sign of a bad developer? though not entirely. I got off college 2 years ago and I'm currently struggling with a University study. Most likely I'll have to drop out and start working within the next couple of months. Now here's the pickle. I have no speciality what so ever. When I got out of college I had worked with C, C++ and Java. I had had an internship at NEC-Philips and got familiar with C# (.NET) and I taught myself how it worked. After college I started working with PHP, HTML,SQL, MySQL Javascript and Jquery. I'm currently teaching myself Ruby on Rails and thus Ruby. At my university I also got familiar with MATLAB. As you can see I've got a broad scope of languages and frameworks I'm familiar with, but none I know inside-out. So I guess this kinda applies to me: "Jack of all trades, master of none.". I've been looking for jobs and I've noticed that most of them require some years of experience with a certain language and some specifications that apply to that language. My question is: How do I pick a speciality? And how do I know if I'll actually enjoy it? As I've worked with loads of languages how would I be able to tell this is right for me? I don't like being tied down to a specific role and I quite like being a generalist. But in order to make more money I would need a specialisation. How would I pick something that goes against my nature? Thanks in advance, Rope.

  • What's a nice explanation for recursion?

    - by Gulshan
    This question is inspired by What's a nice explanation for pointers? So, what can be a nice explanation of the recursion? Update: The idea of recursion is not very common in real world. So, it seems a bit confusing to the novice programmers. Though, I guess, they become used to the concept gradually. So, what can be a nice explanation for them to grasp the idea easily? I expected some detailed answers. N.B. : Even I am going to post one answer. But to be fair, it will be few hours later.

  • Is Python Interpreted or Compiled?

    - by crodjer
    This is just a wondering I had while reading about interpreted and compiled languages. Ruby is no doubt an interpreted language, since source code is compiled by an interpreter at the point of execution. On the contrary C is a compiled language, as one have to compile the source code first according to the machine and then execute. This results is much faster execution. Now coming to Python: A python code (somefile.py) when imported creates a file (somefile.pyc) in the same directory. Let us say the import is done in a python shell or django module. After the import I change the code a bit and execute the imported functions again to find that it is still running the old code. This suggests that *.pyc files are compiled python files similar to executable created after compilation of a C file, though I can't execute *.pyc file directly. When the python file (somefile.py) is executed directly ( ./somefile.py or python somefile.py ) no .pyc file is created and the code is executed as is indicating interpreted behavior. These suggest that a python code is compiled every time it is imported in a new process to crate a .pyc while it is interpreted when directly executed. So which type of language should I consider it as? Interpreted or Compiled? And how does its efficiency compare to interpreted and compiled languages? According to wiki's Interpreted Languages page it is listed as a language compiled to Virtual Machine Code, what is meant by that? Update Looking at the answers it seems that there cannot be a perfect answer to my questions. Languages are not only interpreted or only compiled, but there is a spectrum of possibilities between interpreting and compiling. From the answers by aufather, mipadi, Lenny222, ykombinator, comments and wiki I found out that in python's major implementations it is compiled to bytecode, which is a highly compressed and optimized representation and is machine code for a virtual machine, which is implemented not in hardware, but in the bytecode interpreter. Also the the languages are not interpreted or compiled, but rather language implementations either interpret or compile code. I also found out about Just in time compilation As far as execution speed is concerned the various benchmarks cannot be perfect and depend on context and the task which is being performed. Please tell if I am wrong in my interpretations.

  • OpenGL ES 2.0: Filtering Polygons within VBO

    - by Bunkai.Satori
    Say, I send 10 polygon pairs (one polygon pair == one 2d sprite == one rectangle == two triangles) into OpenGL ES 2.0 VBO. The 10 polygon pairs represent one animated 2D object consisting of 10 frames. The 10 frames, of course, can not be rendered all at the same time, but will be rendered in particular order to make up smooth animation. Would you have an advice, how to pick up proper polygon pair for rendering (4 vertices) inside Vertex Shader from the VBO? Creating separate VBO for each frame would end up with thousands of VBOs, which is not the right way of doing it. I use OpenGL ES 2.0, and VBOs for both Vertices and Indices.

  • Is Haskell worth learning?

    - by Jason K
    I am looking at this question primarily from a career point of view, so I hope you answer it accordingly. I am fairly proficient with Python, can write C++ and I am a final year student of computer science engineering I am looking to learn Haskell because I have heard a lot about it. My question is: apart from learning it because of all the good I have heard about it, is it any good for my career? Is it used in the industry? I am curious to learn it but unless it helps me somehow in my career, I am not willing to make that change at this stage. Looking for some personal experiences here. Thanks!

  • Progressive Enhancement vs. Single Page Apps

    - by SeanPlusPlus
    I just got back from a conference in Boston called An Event Apart. A really popular theme amongst the speakers was the idea of progressive enhancement - a site's content should go in the HTML, and JavaScript should only be used to enhance behavior. The arguments that the speakers gave for progressive enhancement were very compelling. Not only is it a solid pattern for supporting older browsers, and devices on a network with low bandwidth, but HTML fails much more gracefully than JavaScript (i.e. markup that is not supported is just ignored, while if a browser throws an exception while executing your script - you are hosed). Jeremy Keith gave a particularly insightful talk about this. But what about single page web apps like Backbone and Angular? The whole design behind these frameworks seems to push the developer toward moving content out of the HTML, and into something like a JSON API. I can not seem to gel these two design patterns: progressive enhancement vs. single page web apps. Are there instances when one is better than the other? Or are they not even antagonistic technologies, and I am missing something here with my mental model?

  • Reflections based on distance from plane

    - by Andrea Benedetti
    Let's consider, for example, a surface like the volleyball court, we can see that legs and shoes of the players are reflected, with a blur effect, but body and stadium don't (as each object not near to the court). I've already made a reflection effect, but it works as a specular reflection, and I need to achieve an effect like the photo above. So, I would like to make a reflection that is based on the distance between the object and the plane, in this manner a close object would reflect more than an object that is positioned far away from the plane. What is the best way to achieve this effect? My first idea was to use the depth value (taken from the reflected camera), and use that value to blend between reflection and court. But I don't know if it's a correct way. Edit: as rendering engine I use Ogre that already provides a reflections system: reflecting the camera through a plane (obviously I can select the models to draw from the reflected camera). After a render to texture pass I can blend the reflected texture with the original plane. So, if possible, I'm looking for a way that best suits my system.

  • How to cross-reference many character encodings with ASCII OR UTFx?

    - by Garet Claborn
    I'm working with a binary structure, the goal of which is to index the significance of specific bits for any character encoding so that we may trigger events while doing specific checks against the profile. Each character encoding scheme has an associated system record. This record's leading value will be a C++ unsigned long long binary value and signifies the length, in bits, of encoded characters. Following the length are three values, each is a bit field of that length. offset_mask - defines the occurrence of non-printable characters within the min,max of print_mask range_mask - defines the occurrence of the most popular 50% of printable characters print_mask - defines the occurrence value of printable characters The structure of profiles has changed from the op of this question. Most likely I will try to factorize or compress these values in the long-term instead of starting out with ranges after reading more. I have to write some of the core functionality for these main reasons. It has to fit into a particular event architecture we are using, Better understanding of character encoding. I'm about to need it. Integrating into non-linear design is excluding many libraries without special hooks. I'm unsure if there is a standard, cross-encoding mechanism for communicating such data already. I'm just starting to look into how chardet might do profiling as suggested by @amon. The Unicode BOM would be easily enough (for my current project) if all encodings were Unicode. Of course ideally, one would like to support all encodings, but I'm not asking about implementation - only the general case. How can these profiles be efficiently populated, to produce a set of bitmasks which we can use to match strings with common characters in multiple languages? If you have any editing suggestions please feel free, I am a lightweight when it comes to localization, which is why I'm trying to reach out to the more experienced. Any caveats you may be able to help with will be appreciated.
