  • what should a developer know/address to build commercial Android Apps ?

    - by giulio
    Android and mobile development is an exciting area of development. As it is a new discipline, what would be expected of an android developer to build commercially robust applications in terms of skills ? The problem that I and, i think, many other "noobs" into the technology would like to know are the areas of technical skills and the progression to the required advanced topics that goes beyond the the very basics provided by Google. There is a lot of information that's quite useful but its not organised into categories of discipline nor order.

  • Projects to learn web development

    - by David McDavidson
    I'm trying to get a job as a web developer, but the great majority of jobs offers requires previous experience and a portfolio to prove you've got the required skills. Unfortunately I don't have any real experience or anything to show. The best way to learn is to try and tackle real world problems, so I'd like to know what would be some nice projects to learn stuff and that will look good in a portfolio?

  • Is there a sequence to read through the Android Developer Site for a user new to Android?

    - by Paul
    I keep seeing that I don't need to buy an android development book, that I should just read the Android Developer Site site because it has everything I need to know. I see it more as drinking from a fire hose. But I'm one of those people who likes to be walked thru the basics. I like to build up my knowledge, rather than being dropped into reference documentation. I also like to make sure I have see all/most of the topics covered. I'd hate to develop the wrong thing because I don't know about Fragments, Content Providers, or whatever. So, since it's a great resource, better than any book (we don't need no stinkin books), how do I traverse the site to get the information provide in the same way as a book would lay it out?

  • How can I find a good open source project to join?

    - by Lord Torgamus
    I just started working a year ago, and I want to join an open source project for the same reasons as anyone else: help create something useful and develop my skills further. My problem is, I don't know how to find a project where I'll fit in. How can I find a beginner-friendly project? What attributes should I be searching for? What are warning signs that a project might not be the right fit? Are there any tools out there to help match people with open source projects? There's a similar question here, but that question has to do with employment and is limited to PHP/Drupal.

  • How is programming affected by spatial aptitude?

    - by natli
    The longer I work on a project, the less clear it becomes. It's like I cannot seperate various classes/objects anymore in my head. Everything starts mixing up, and it's extremely hard to take it all apart again. I start putting functions in classes where they really don't belong, and make silly mistakes such as writing code that I later find was 100% obsolete; things are no longer clearly mappable in my head. It isn't until I take a step back for several hours (or days somtimes!) that I can actually see what's going on again, and be productive. I usually try to fight through this, I am so passionate about coding that I wouldn't for the life of me know what else I could be doing. This is when stuff can get really weird, I get so up in my head that I sort of lose touch with reality (to some extent) in that various actions, such as pouring a glass of water, no longer happen on a concious level. It happens on auto pilot, during which pretty much all of my concious concentration (is that even a thing?) is devoted to borderline pointless problem solving (trying to seperate elements of code). It feels like a losing battle. So I took an IQ test a while ago (Wechsler Adult Intelligence Scale I believe it was) and it turned out my Spatial Aptitude was quite low. I still got a decent score, just above average, so I won't have to poke things with a stick for a living, but I am a little worried that this is such a handicap when writing/engineering computer programs that I won't ever be able to do it seriously or professionally. I am very much interested in what other people think of this.. could a low spatial aptitude be the cause of the above described problems? Maybe I should be looking more along the lines of ADD or something similar, because I did get diagnosed with ADD at the age of 17 (5 years ago) but the medicine I received didn't seem to affect me that much so I never took it all that serious. Sorry if I got a little off topic there, I know this is not a mental help board, the question should be clear; How is programming affected by spatial aptitude? As far as I know people are born with low/med/high spatial aptitude, so I think it's interesting to find out if the more fortunate are better programmers by birth right.

  • Being a good mentee - a protégé.

    - by marked
    The complement of the Being a good mentor question. I work with many very senior people that have vast amounts of knowledge and wisdom in Software, Engineering and our business domain. What are some tips for gaining as much knowledge from them? I don't want to take up too much of their time, but also want to take full advantage of this since it really could help develop my skills. What are some good questions to get the conversation rolling in a sit down mentor/mentee session? Some of the people providing mentorship have little experience in this area, so it would help to be able to lead some of these discussions.

  • What are the most important programming skills you need to improve as a team Leader or project manager?

    - by Aba Dov
    I decided to ask this question after I read the valuable answers to the great question What is the single most effective thing you did to improve your programming skills? and after attending Ad Burns "Secrets of a rock star programmer". It made me think about me and what programming skills I try to improve. I came to realize that there should be a difference in the programming skills you try to improve as developer and the programming skills you should improve as a team leader or project manager. My question is: What are the most important programming skills you need to improve as a team Leader or project manager? What would you recommend to others that want to improve?

  • How to convince my boss to improve code quality?

    - by Vimvq1987
    The place I'm working for is a service provider. We have a lot of services, which are written to deal with deadline, so their code are really terrible: No coding convention, everyone codes in his own style No unit testing (which is really bad) No refactoring (which is truly worse) No automation build/deployment etc and these code are used again and again, so bad code continue to spread all over my department. I really want to set up a standard quality for our code, by requiring everyone to follow "rules": every line of code which does not follow convention will be rejected, and every function of code which does not pass unit testing will not be committed,...But I don't know how to convince my boss to allow me to do this. I'm relatively new comer, so inspiring people from my works is really hard, and I think it's easier if my boss support me to this. Thank you very much for your advices

  • What is the best way to become a professional in PHP and Website Building?

    - by Mr.TAMER
    I would like to become a professional in php, I have learned nearly all about the language syntax and concepts and I have a good knowledge in C and C++, which made it easier to become familiar with PHP. (Of course, I learned MySql too.) But I don't feel like being able to build even a little good website of my own! It looks like PHP is all about knowing lots of functions and using them, while in fact I don't think it's like that, is it? How can I become a professional in PHP and Website Building? I would do anything and spend whatever amount of time required for that. EDIT I've also a very good knowledge in HTML and a normal knowledge in CSS and JavaScript. Sorry for not mentioning that, I just thought it was implicitly included.

  • What algorithm(s) can be used to achieve reasonably good next word prediction?

    - by yati sagade
    What is a good way of implementing "next-word prediction"? For example, the user types "I am" and the system suggests "a" and "not" (or possibly others) as the next word. I am aware of a method that uses Markov Chains and some training text(obviously) to more or less achieve this. But I read somewhere that this method is very restrictive and applies to very simple cases. I understand basics of neural networks and genetic algorithms(though have never used them in a serious project) and maybe they could be of some help. I wonder if there are any algorithms that, given appropriate training text(e.g., newspaper articles, and the user's own typing) can come up with reasonably appropriate suggestions for the next word. If not (links to)algorithms, general high-level methods to attack this problem are welcome.

  • Resources for Virtual Machine programming

    - by good_computer
    I am a beginner (a little more than that) programmer of C. I am really interested in the field of Virtual Machines. When I read about the Python VM, the PyPy project, the advancements in JVM technology, Google V8, the Erlang VM, I really get excited about these amazing pieces of technology, and really want to get my hands dirty building them or contributing to one of these projects. I need to know.. what are the things (language, concepts, algorithms, math, etc?) I need to know/learn to be able to build a virtual machine any books or other resources that will be helpful career prospects for a virtual machine engineer (but this is least important for me for now) (one more side question: somewhere I'd read something like JVM is on the cutting edge of virtual machine technology -- that it is the most advanced VM so far -- is that true?) Please give me a LONG answer detailing all that you know.

  • Are there currently any modern, standardized, aptitude test for software engineering?

    - by Matthew Patrick Cashatt
    Background I am a working software engineer who is in the midst of seeking out a new contract for the next year or so. In my search, I am enduring several absurd technical interviews as indicated by this popular question I asked earlier today. Even if the questions I was being asked weren't almost always absurd, I would be tired nonetheless of answering them many times over for various contract opportunities. So this got me thinking that having a standardized exam that working software professionals could take would provide a common scorecard that could be referenced by interviewers in lieu of absurd technical interview questions (i.e. nerd hazing). Question Is there a standardized software engineering aptitude test (SEAT??) available for working professionals to take? If there isn't a such an exam out there, what questions or topics should be covered? An additional thought Please keep in mind, if suggesting a question or topic, to focus on questions or topics that would be relevant to contemporary development practices and realistic needs in the workforce as that would be the point of a standard aptitude test. In other words, no clown traversal questions.

  • How should I study programming languages?

    - by gcc
    I am a student of computer engineering. I have never done any programming before, and as you can understand, I don't know how to study it or how to make my own programs. My English is weak [edited for clarity - ed], and so if you don't like the choices I list, please feel free to provide others. How should I study? How should I learn programming languages? Study completely from a book. Don't study from a book, just try writing code. A mix of the two; study from a book, then try writing code. Study half the book, then write the code by hand on paper. Listed to the teacher, then try to solve general problems (those not from any specific chapter).

  • Getting into C# and MVC4 coming from Javascript

    - by Stefan V.
    Let me know if this is the wrong place to ask this but, I am trying to get into a backend/server language coming from a front-end javascript background (vanilla, angular, jQuery and a bit of node and mongodb, also some experience with PHP and MySQL). Why C#? My company's entire server-side is MVC4. Occasionally, I am going through commits of the backend guys and have asked them all sorts of questions. A lot of what I have heard and seen just seems appealing. Anyway, I'd rather start with C# first and gradually adopt .NET MVC. Does anybody advice, tips, recommended books, etc for somebody trying to learn C# coming from a JS background?

  • CS subjects that an undergraduate must know.

    - by Karl
    In college, I was never interested in theory. I never read it. No matter how much I tried, I was unable to read stuff and not know what was actually happening practically. Like for example, in my course on automata theory, my professor told me everything possibly related to the mathematical aspect of it, but not even once did he mention where it would be used practically. This is just an example. I managed to pass my college and interned with a company also, where I did a project and thankfully they didn't bother about my grades, as they were above average. Now, I am interested in knowing what subjects should a CS student must absolutely and positively be aware of? Subjects that can have relevance in the industry. This is because I have some free time on my hands and it would help me better to have a good understanding of them. What are your suggestions? Like for one, algorithms is one subject.

  • Is there a Railstutorial-quality tutorial for a PHP framework?

    - by tnorthcutt
    Is there a tutorial along the lines of Michael Hartl's Rails Tutorial for a (widely used) PHP framework? Obviously there are tons of tutorials for e.g. Codeigniter, CakePHP, Symfony, etc., but I haven't been able to find one that is as extensive as Rails Tutorial is. Ideally, I'd like something that takes you from nothing to building a complete, functioning application with at least a decent amount of complexity.

  • HTG Explains: How System Restore Works in Windows

    - by Chris Hoffman
    System Restore is a Windows feature that can help fix some crashes and other computer problems. To know when to use it, you’ll have to understand just how System Restore works. System Restore can’t solve every problem – for example, you can’t use it to restore your personal files if they’re accidentally deleted or modified. However, it’s another tool you can use when your computer isn’t working properly.

  • Is using ELSE bad programming?

    - by dave.b
    I've often come across bugs that have been caused by using the ELSE construct. A prime example is something along the lines of: If (passwordCheck() == false){ displayMessage(); }else{ letThemIn(); } To me this screams security problem. I know that passwordCheck is likely to be a boolean, but I wouldn't place my applications security on it. What would happen if its a string, int etc? I usually try to avoid using ELSE, and instead opt for two completely separate IF statements to test for what I expect. Anything else then either gets ignored OR is specifically handled. Surely this is a better way to prevent bugs / security issues entering your app. How do you guys do it?

  • Methods of ordering function definitions in code

    - by xralf
    When I work on some programming project (usually command line application in Python with many switches), I'm usually creating about 30 and more functions. Most of the functions are in one file (except some helpers that I utilize in more projects). Some of the functions are called on particular switch (like -p or --print) but many functions do some helper computations, print operations or database operations because I don't want to main functions be too large. When I have an idea for a new functionality I often put new functions randomly to the file. Should I think more about it and place it to some particular place? Are there some methods for this?

  • What's the best way to get up to speed with Java?

    - by Kosta
    I'm a software developer that just switched teams so I shall write code in Java now. Last time I wrote something in the language was in programming 101 at uni (I was already an amateur coder back then). So what is the best book/tutorial to get up to speed with Java? Where's the Java - the good parts? Learn you some Java for great good? Learn Java the hard way? Or is it too enterprisey for that kind of passion...?

  • Why is it always "what language should I learn next" instead of "what project should I tackle next"?

    - by MikeRand
    Hi all, Why do beginning programmers (like me) always ask about the next language they should learn instead of asking about the next project to tackle? Why did Eric Raymond, in the "Learn How To Program" section of his "How To Become A Hacker" essay, talk about the order in which you should learn languages (vs. the order in which you should tackle projects). Do beginning carpenters ask "I know how to use a hammer ... should I learn how to use a saw or a level next?" I ask because I'm finding that almost any meaningful project I'm interested in tackling (e.g. a web app, a set of poker analysis tools) requires that I learn just enough of a multitude of languages (Python, C, HTML, CSS, Javascript, SQL) and frameworks/libraries (wxPython, tkinter, Django) to implement them. Thanks, Mike

  • problems with studying algorithms

    - by rookie
    hello everyone, I'm currently studying computer science at the Institute, and I have some problems with course which is named Algorithms, I've just begun to study it, but I'm already feeling, that I'm going to fail it, my problem is that while understanding different algorithms on graphs I need to keep in my mind a lot of info, and usually I can't do it, I forget some points of the exercise or can't proceed to final result, I'm very desperate about it cause I like programming very much. Did somebody feel the same while studying in the University? thanks in advance for any help P.S. I began to program only two years ago, may it be the problem?

  • Reaching Intermediate Programming Status

    - by George Stocker
    I am a software engineer that's had positions programming in VBA (though I dare not consider that 'real' experience, as it was trial and error!), Perl w/ CGI, C#, and ASP.NET. The latter two are post-undergraduate, with my entrance into the 'real world'. I'm 2 years out of college, and have had 5 years of experience (total) across the languages I've mentioned. However, when it comes to my resume, I can only put 2 years down for C#, and less than a year down for ASP.NET. I feel like I know C#, but I still have to spend time going 'What does this method do?', whereas some of the more senior level engineers can immediately say, "Oh, Method X does this, without ever having looked at that method before." So I know empirically that there's a gulf there, but I'm not exactly sure how to bridge it. I've started programming in Project Euler, and I picked up a book on design patterns, but I still feel like I spend each day treading water, instead of moving forward. That isn't to say that I don't feel like I've made progress, it just means that as far as I come each day, I still see the mountain top way off in the distance. My question is this: How did you overcome this plateau? How long did it take you? What methods can you suggest to assist me in this? I've read through Code Complete, The Mythical Man Month, and CLR via C#, 2nd edition -- my question is: What do I do now? Edit: I just found this question on projects for an intermediate level programmer. I think it adds to the discussion (though it does not supplant my question). As such, I'm adding it to the question as a "For More Information".

  • How to learn what the industry standards/expectations are, particularly with security?

    - by Aerovistae
    For instance, I was making my first mobile web-application about a year ago, and half-way through, someone pointed me to jQuery Mobile. Obviously this induced a total revolution in my app. Rewrote everything. Now, if you're in the field long enough, maybe that seems like common knowledge, but I was totally new to it. But this set me wondering: there are so many libraries and extensions and frameworks. This seems particularly crucial in the category of security. I'm afraid I'm going to find myself doing something in a professional setting eventually (I'm still a student) and someone's going to walk over and be like, My god, you're trying to secure user data that way? Don't you know about the Gordon-Wokker crypto-magic-hash-algorithms library? Without it you may as well go plaintext. How do you know what the best ways are to maximize security? Especially if you're trying to develop something on your own...

  • How can I make myself better at programming working at a shi* job ?

    - by Scrooge
    I recently graduated with an Engineering degree in Computer Science, but my employer (a mid-sized software company) is not using my logical and programming skills. I want to move to a better opportunity but how do I do that since my experience here is not going to count as much? How do I get a better programming job? The worst part is that I am still reading from books (and not writing code myself) even after I have started working. They are paying me a standard entry level Indian IT job rate but I really dont care. It's not worth it. Please advise as to how I can do something worthwhile. (I have studied C++; Core Java; Ruby On Rails ..made a couple of academic projects but no relevant practical real world experience). Just to make things easier .. let me list a few basic queries How I get better at programming without a good project at my company? Please suggest projects where I can learn to write practical code (platform doesn't matter) Best place to take part in open source development? Is it possible that I earn slightly more while I learn? (apart from my sh** job I mean) What kind of practical projects are best suited for me? (ie for an entry level programmer)
