  • Is there a language between C and C++?

    - by Robert Martin
    I really like the simple and transparent nature of C: when I write C code I feel unencumbered by "leaky abstractions" and can almost always make a shrewd guess as to the assembly I'm producing. I also like the simple, familiar syntax for C. However, C doesn't have these simple, helpful doodads that C++ offers like classes, simplified non-cstring handling, etc. I know that it's all possible to implement in C using jump tables and the like, but that's a bit wordy at times, and not very type-safe for various reasons. I'm not a fan of the over-emphasis on objects in C++, though, and I'm gun shy of the 'new' operator and the like. C++ seems to have just a few too many hiccups to, for instance, be used as a system programming language. Does there exist a language that sits between C and C++ on the scale of widgets and doodads? Disclaimer: I mean this as purely a factual question. I do not intend to anger you because I don't share your view that C{,++} is good enough to do whatever I'm planning.

  • Algorithms and Programmer's day-to-day job

    - by Lior Kogan
    As of July 10, 2012, Stack Overflow contains 3,345,864 questions, out of which 20,840 questions are tagged as "Algorithm" - this is less than 0.6% ! I find it disturbing. Many programmers have several years of academic education in computer science / software engineering. Most of them are smart... When asked, most would say that they love algorithms. Computer programming is generally about solving problems using algorithms... Yet, only 1 of 160 questions is tagged as algorithm related. What does it say about our profession?

  • As a young student aspiring to have a career as a programmer, how should I feel about open source software?

    - by Matt
    Every once in a while on some technology websites a headline like this will pop up: http://www.osor.eu/news/nl-moving-to-open-source-would-save-government-one-to-four-billion My initial thought about government and organizations moving to open source software is that tons of programmers would lose their jobs and the industry would shrink. At the same time the proliferation and use of open source software seems to be greatly encouraged in many programming communities. Is my thinking that the full embrace of open source software everywhere will hurt the software industry a misconception? If it is not, then why do so many programmers love open source software?

  • Can a programmer get too smart for their own good?

    - by P.Brian.Mackey
    The more I learn about programming, the more things I see that could be improved by a great deal. Often, a companies process management is total SWAG or they have Frames based websites written recently, .NET 1.1 based code, no separation of concerns, poor quality control...I could go on and on and on... Projects can succeed, but there tends to be so much waste I am amazed at how much time and money a company can throw away. I've seen it happen at several companies. So is it that ignorance truly is bliss? UPDATE Question "How is it that top developers (I don't mean like Jon Skeet level, I mean guys who are dedicated enough to hit a forum and try for self-improvement) even want to code anymore after they see the often insurmountable sociological and technical problems they are told to fix, but then scolded for doing so? "

  • Feeling a bit... under-challenged in my university course

    - by Corey
    I'm currently a sophomore at my university, majoring in Computer Science. Obviously, there are some programming courses as part of my curriculum. However, I'm feeling very underwhelmed by its progress. I've self-taught myself a lot and like to code in my spare time as a hobby. I'm currently in Computer Science II. I never took CS 1 because it seemed rather basic -- I asked someone in the department if they would override my CS 1 requirement if I passed their final (which I did with flying colors). Anyway, the class is going by quite slowly. It seems like the rest of the class has a hard time understanding some basic concepts, which the professor needs to keep going over to help them understand. Is this normal? Looking at the class schedule, I seem to know everything except for one or two things near the very end of the semester. Is there a different perspective I can look at this through so it doesn't seem so boring?

  • Programmers that need a lot of "Outside Help" - Is this bad?

    - by Zanneth
    Does anyone else think it's kind of tacky or poor practice when programmers use an unusual amount of libraries/frameworks to accomplish certain tasks? I'm working with someone on a relatively simple programming project involving geolocation queries. The guy seems like an amateur to me. For the server software, this guy used Python, Django, and a bunch of other crazy libraries ("PostGIS + gdal, geoip, and a few other spatial libraries" he writes) to create it. He wrote the entire program in one method (in views.py, nonetheless facepalm), and it's almost unreadable. Is this bad? Does anyone else think that this is really tacky and amateurish? Am I the only minimalist out there these days?

  • Multiple Object Instantiation

    - by Ricky Baby
    I am trying to get my head around object oriented programming as it pertains to web development (more specifically PHP). I understand inheritance and abstraction etc, and know all the "buzz-words" like encapsulation and single purpose and why I should be doing all this. But my knowledge is falling short with actually creating objects that relate to the data I have in my database, creating a single object that a representative of a single entity makes sense, but what are the best practises when creating 100, 1,000 or 10,000 objects of the same type. for instance, when trying to display a list of the items, ideally I would like to be consistent with the objects I use, but where exactly should I run the query/get the data to populate the object(s) as running 10,000 queries seems wasteful. As an example, say I have a database of cats, and I want a list of all black cats, do I need to set up a FactoryObject which grabs the data needed for each cat from my database, then passes that data into each individual CatObject and returns the results in a array/object - or should I pass each CatObject it's identifier and let it populate itself in a separate query.

  • Are there any resources on how to identify problems that could best be solved with templates?

    - by sap
    I decided to improve my knowledge in template meta-programming. I know the syntax and rules and been playing with counteless examples from online resources. I understand how powerful templates can be and how much compile time optimization they can provide but I still cant "think in templates", I can't seem to know by myself if a certain problem could be best solved with templates and if it can, how to adapt that problem to templates. Is there some kind of online resource or book that teaches how to identify problems that could best be solved with templates and how to adapt that problem?

  • Improving without mentor

    - by speeder
    Although I consider myself not much experienced, I keep landing in jobs as the leader somehow (in the current one I am tech director of the company, in a previous one I was the R&D head). I understand why this happen (I have a certain specific set of skills, and I use some uncommon programming languages), my issue is: I cannot find a mentor... I know there must be stuff to me learn, and I notice as I work over the years that I am slowly learning more and more, but I believe that there are some way to get better much faster than just coding... So, how I improve when there are no other person in the company to teach me, or to me read their code? (or fix their code even...) I think I am beyond books, but way below a "master" level, so I don't know where to learn more.

  • Good resources and tools for modern, heavy JavaScript development?

    - by Matt Greer
    I am interested in doing some projects that involve heavy use of JavaScript. Namely HTML5 based canvas games, potentially using node.js as well. I am interested in learning modern best practices, tools and resources for JavaScript. JavaScript is tough to research because you end up wading through a lot of really outdated material, hailing from the times that "JavaScript" was a four letter word. If you are heavily involved in JavaScript programming... What text editor or IDE do you use? What unit testing framework do you use? Do you use Selenium, or something else? What other tools do you use? What communities exist that discuss recent advents in JavaScript? What books do you read/refer to? What blogs do you read?

  • Android Development: MVC vs MVVM

    - by Mel
    I've started coding for android and I'm having difficulty trying to properly partition my code. I always end up with a very tight coupling between my UI logic and the actual controls I use to represent them. I have background in both WPF MVVM and ASP.net MVC so I'm familiar with those patterns. After some digging, I found Android Binding. It seems nice and fits nicely with my WPF background. However, it bugs me that its not built in. I'm pretty sure that the android makers have thought of this when designing the android programming interface. So my question is, what is the best practice pattern to use when developing in android, if any. I have looked and looked at their site but didn't find anything...

  • How much to charge Ruby on Rails Website [closed]

    - by eWizardII
    I figured it be appropriate to ask this question on webmasters, over the stackoverflow site seeing as there are similar questions here. I am freelancing for a client in the Boston area, who has the html/css templates for their site made by another web designer. They are basically looking for someone to set up the template, and then make the backend so that a user can purchase music on their site (they are musicians). I am wondering then what would be an appropriate amount to charge them to develop such a system, I am a student, and this would be my 3rd Ruby on Rails project, but probably at least the 20 web design project I have been hired to do and I have other programming knowledge, Python, C, etc. I am thinking of suggesting that they pay 1000usd to set up such a system, but I don't know if this is appropriate. To me it seems justifiable given my experience, and the low end of RoR developers I have seen charging 25usd/hr all the way up to 150usd/hr. Any advice would be appreciated.

  • Is there such a thing as too much experience?

    - by sunpech
    For modern software developers in today's world, is there such a thing as having too much experience with a certain technology or programming language? To a recruiter, interviewer, or company hiring-- could there often be cases where a particular candidate has so much experience in a certain area or technology where it works against the candidate to being hired? I'm not talking about cases where a senior developer is applying for an entry-level developer position, and has a lot of experience in that sense. Nor am I talking about cases where a candidate is outright lying (e.g. 20+ years experience with Ruby on Rails). I've overheard this in conversations between hiring managers/developers during happy hours, yet I'm not quite sure I fully understand what they mean.

  • Object-Oriented Operating System

    - by nmagerko
    As I thought about writing an operating system, I came across a point that I really couldn't figure out on my own: Can an operating system truly be written in an Object-Oriented Programming (OOP) Language? Being that these types of languages do not allow for direct accessing of memory, wouldn't this make it impossible for a developer to write an entire operating system using only an OOP Language? Take, for example, the Android Operating System that runs many phones and some tablets in use around the world. I believe that this operating system uses only Java, an Object-Oriented language. In Java, I have been unsuccessful in trying to point at and manipulate a specific memory address that the run-time environment (JRE) has not assigned to my program implicitly. In C, C++, and other non-OOP languages, I can do this in a few lines. So this makes me question whether or not an operating system can be written in an OOP, especially Java. Any counterexamples or other information is appreciated.

  • junior / professional / senior categorization

    - by oozoo
    Hey guys, is it just me or is the categorization of developer levels highly subjective? I get the feeling that every company tries to hire experienced developers as juniors because they don't know $technology. For example my own career: I switched technologies a couple of times, while sticking to java as a programming language. For example I first worked for 3 years using JavaSE technologies, the next company I worked for hired me as junior because I didn't have JavaEE experience - while still selling me as professional level to customers (I work in consulting). The next company hired me again as junior because I didn't have SAP experience - they mostly work with SAP Java technologies which is definitely a niche. Still, they are selling all their technology consultants for exactly the same rate while paying them significantly different wages. Now when switching jobs again I feel like this whole thing is going to start all over again because I don't have Spring experience or Oracle knowledge. tl;dr = is my observation totally off base that companies are just using these categorizations as means to keep down wages?

  • What Master degree should a programmer have after "ITC"? [closed]

    - by Saleh Feek
    I am sorry if the question is simple. I studied ITC - Information Technology and Computing program, in an Arab university called "Arab Open University". This university actually takes the courses from the Open University in the UK (through a partnership). (Note: some of the courses in the list are different from what I took due to replacement/updating for materials) .......... I am interested in programming in general. It is the same question but in different ways: What is the master degree that is related to a programmer? Generally for someone like me, what is the required/suggested Master degree? For any suggested Master degree please type the formal name for the master degree, so that I can search for it.

  • Do employers prefer software engineering over CS majors?

    - by Joey Green
    I'm in grad school at a university that was one of the first to have a software engineering accredited program. My undergrad is in CS. An employer recently recruited at our university and hired 5 SE majors. None of them were CS. Do employers prefer software engineering majors? The reason I ask is because I can focus on many different areas during my graduate studies and really want to take the classes that will help me land a great job. Right now I'm either going to use CUDA and parallelize an advanced ray-tracer for a graduate project or do research on non-photo-realistic rendering in augmented reality. Pursuing these would leave very little SE classes in my schedule. If I went the software engineering route, I would probably either do research into data-oriented programming or software design complexity. Sometimes I think when I'm 40 and look back will it matter at all? For some reason I'm thinking not.

  • Is paying programmers to "test" for bugs normal? [on hold]

    - by user106277
    I recently hired a programming team to do a port of my iPad app to the iPhone and Android platforms. I also wanted them to implement a bunch of tips on how to play the app, similar like you would find in Candy Crush or Cut the Rope. They want to charge 12 hours @ $35/hr for the "Testing all of the Tips", telling me that normally it would take them more than 25 hours but that they will 'bear the difference'. I have never heard of this, but maybe it's a new practice? I am used to devs doing their own quality control, and then having a testing/acceptance period... Am I missing something? Thanks for any help and advice you can give!

  • How to hide Thinking at Work so that the Non-Programmers don't suspect Slacking?

    - by stesch
    Better programmers than me can write in essays about walking around with a coffee mug and call it programming. And it's perfectly accepted at a place that knows the business. Or see what Gregory House (TV show "House M.D.") does when he is thinking. But what about the other places where you are the only programmer? If you don't stare at boring stuff on the monitor for 8 hours straight, co-workers suspect you being a slacker. Yes, not the managers who see the output. Only the co-workers who see the process and can't relate to this kind of work. Yesterday I had to explain to a trainee of some other profession that software development is like flying. The explanation from the Hitchhiker's Guide to the Galaxy. I don't think she bought it.

  • Reuseable Platform For Custom Board Game

    - by George Bailey
    Is there a generic platform to allow me to customize the rules to a board game. The board game uses a square grid, similar to Checkers or Chess. I was hoping to take some of the work out of creating this computer opponent, by reusing what is already written. I would think that there would be a pre-written routine for deciding which moves would lead to the best outcome, and all that I would need to program is the pieces, legal moves, what layout constitutes a win/lose or draw, and perhaps some kind of scoring for value of pieces. I have seen chess programs that appear to use a recursive routine, so they think anywhere from 2 to 20 moves ahead to create varying degrees of difficulty. I have noticed this on chess.com. The game I am programming will not be as complex. Is there a platform designed to be re-used for different grid/piece based games. JavaScript would be preferable, but Java or Perl would be acceptable.

  • Where To Begin To Make A Website

    - by lolyoshi
    I'm a newbie in web programming. I haven't done anything that relates to website before. Now, my new task is creating a website using Java, Jsp, HTML, CSS, mySQL, Apache and Spring Framework (MVC model). I want to know what I should research if I want my website has the function as post entries, comment entries, delete entries, edit entries, etc as a forum? Which I need to know beside above things? I don't know how to update my website automatically when there're changes in website as the top view products, the best products. I don't think I'll input or change them manually. So, which tools or language can support that? Thank for advance

  • Expectations + Rewards = Innovation

    - by D'Arcy Lussier
    “Innovation” is a heavy word. We regard those that embrace it as “Innovators”. We describe organizations as being “Innovative”. We hold those associated with the word in high regard, even though its dictionary definition is very simple: Introducing something new. What our culture has done is wrapped Innovation in white robes and a gold crown. Innovation is rarely just introducing something new. Innovations and innovators are typically associated with other terms: groundbreaking, genius, industry-changing, creative, leading. Being a true innovator and creating innovations are a big deal, and something companies try to strive for…or at least say they strive for. There’s huge value in being recognized as an innovator in an industry, since the idea is that innovation equates to increased profitability. IBM ran an ad a few years back that showed what their view of innovation is: “The point of innovation is to make actual money.” If the money aspect makes you feel uneasy, consider it another way: the point of innovation is to <insert payoff here>. Companies that innovate will be more successful. Non-profits that innovate can better serve their target clients. Governments that innovate can better provide services to their citizens. True innovation is not easy to come by though. As with anything in business, how well an organization will innovate is reliant on the employees it retains, the expectations placed on those employees, and the rewards available to them. In a previous blog post I talked about one formula: Right Employees + Happy Employees = Productive Employees I want to introduce a new one, that builds upon the previous one: Expectations + Rewards = Innovation  The level of innovation your organization will realize is directly associated with the expectations you place on your staff and the rewards you make available to them. Expectations We may feel uncomfortable with the idea of placing expectations on our staff, mainly because expectation has somewhat of a negative or cold connotation to it: “I expect you to act this way or else!” The problem is in the or-else part…we focus on the negative aspects of failing to meet expectations instead of looking at the positive side. “I expect you to act this way because it will produce <insert benefit here>”. Expectations should not be set to punish but instead be set to ensure quality. At a recent conference I spoke with some Microsoft employees who told me that you have five years from starting with the company to reach a “Senior” level. If you don’t, then you’re let go. The expectation Microsoft placed on their staff is that they should be working towards improving themselves, taking more responsibility, and thus ensure that there is a constant level of quality in the workforce. Rewards Let me be clear: a paycheck is not a reward. A paycheck is simply the employer’s responsibility in the employee/employer relationship. A paycheck will never be the key motivator to drive innovation. Offering employees something over and above their required compensation can spur them to greater performance and achievement. Working in the food service industry, this tactic was used again and again: whoever has the highest sales over lunch will receive a free lunch/gift certificate/entry into a draw/etc. There was something to strive for, to try beyond the baseline of what our serving jobs were. It was through this that innovative sales techniques would be tried and honed, with key servers being top sellers time and time again. At a code camp I spoke at, I was amazed to see that all the employees from one company receive $100 Visa gift cards as a thank you for taking time to speak. Again, offering something over and above that can give that extra push for employees. Rewards work. But what about the fairness angle? In the restaurant example I gave, there were servers that would never win the competition. They just weren’t good enough at selling and never seemed to get better. So should those that did work at performing better and produce more sales for the restaurant not get rewarded because those who weren’t working at performing better might get upset? Of course not! Organizations succeed because of their top performers and those that strive to join their ranks. The Expectation/Reward Graph While the Expectations + Rewards = Innovation formula may seem like a simple mathematics formula, there’s much more going under the hood. In fact there are three different outcomes that could occur based on what you put in as values for Expectations and Rewards. Consider the graph below and the descriptions that follow: Disgruntled – High Expectation, Low Reward I worked at a company where the mantra was “Company First, Because We Pay You”. Even today I still hear stories of how this sentiment continues to be perpetuated: They provide you a paycheck and a means to live, therefore you should always put them as your top priority. Of course, this is a huge imbalance in the expectation/reward equation. Why would anyone willingly meet high expectations of availability, workload, deadlines, etc. when there is no reward other than a paycheck to show for it? Remember: paychecks are not rewards! Instead, you see employees be disgruntled which not only affects the level of production but also the level of quality within an organization. It also means that you see higher turnover. Complacent – Low Expectation, Low Reward Complacency is a systemic problem that typically exists throughout all levels of an organization. With no real expectations or rewards, nobody needs to excel. In fact, those that do try to innovate, improve, or introduce new things into the organization might be shunned or pushed out by the rest of the staff who are just doing things the same way they’ve always done it. The bigger issue for the organization with low/low values is that at best they’ll never grow beyond their current size (and may shrink actually), and at worst will cease to exist. Entitled – Low Expectation, High Reward It’s one thing to say you have the best people and reward them as such, but its another thing to actually have the best people and reward them as such. Organizations with Entitled employees are the former: their organization provides them with all types of comforts, benefits, and perks. But there’s no requirement before the rewards are dolled out, and there’s no short-list of who receives the rewards. Everyone in the company is treated the same and is given equal share of the spoils. Entitlement is actually almost identical with Complacency with one notable difference: just try to introduce higher expectations into an entitled organization! Entitled employees have been spoiled for so long that they can’t fathom having rewards taken from them, or having to achieve specific levels of performance before attaining them. Those running the organization also buy in to the Entitled sentiment, feeling that they must persist the same level of comforts to appease their staff…even though the quality of the employee pool may be suspect. Innovative – High Expectation, High Reward Finally we have the Innovative organization which places high expectations but also provides high rewards. This organization gets it: if you truly want the best employees you need to apply equal doses of pressure and praise. Realize that I’m not suggesting crazy overtime or un-realistic working conditions. I do not agree with the “Glengary-Glenross” method of encouragement. But as anyone who follows sports can tell you, the teams that win are the ones where the coaches push their players to be their best; to achieve new levels of performance that they didn’t know they could receive. And the result for the players is more money, fame, and opportunity. It’s in this environment that organizations can focus on innovation – true innovation that builds the business and allows everyone involved to truly benefit. In Closing Organizations love to use the word “Innovation” and its derivatives, but very few actually do innovate. For many, the term has just become another marketing buzzword to lump in with all the other business terms that get overused. But for those organizations that truly get the value of innovation, they will be the ones surging forward while other companies simply fade into the background. And they will be the organizations that expect more from their employees, and give them their just rewards.
