• How can a large company foster excellence in its engineers?

  - by Joshiatto

  I am tasked with improving the skills (quality & speed) of engineers in my company. Here are some ideas: Pair Programming TDD Automated Check-in Policies Talks given by experts Awards for coding excellence Encourage competition among engineers to contribute to GitHub Publish standards and practices docs on the intranet site "Gamification" of engineering. Somehow make becoming badasses into a game they will enjoy playing Training Showcase github checkins on screens around the office Add an "engineer of the month" to the intranet home page How can I drive traffic to the intranet home page? What crazy futuristic idea would drive engineers to go to the page every day to see who of their peers are making more money than them (inferred via recognition) and then go off and improve their skills and productivity to see their standings improve on the home page??? Or any ideas just to foster collaboration and love for their jobs so they start taking more pride in their work?? Don't take my ideas as symptomatic of our org. I take full responsibility for not knowing the right way to do this.

• I want to turn VB.Net Option Strict On

  - by asjohnson

  I recently found out about strong typing in VB.Net (naturally it was on here, thanks!) and am deciding I should take another step toward being a better programmer. I went from vba macros - VB.Net, because I needed a program that I could automate and I never read anything about strong typing, so I kind of fell into the VB.Net default trap. Now I am looking to turn it on and sort out this whole type thing. I was hoping someone could direct me towards some resources to make this transistion as painless as possible. I have read around some and ctype seems to come up a lot, but past that I am at a bit of a loss. What are the benefits of switching? Is there more to it than just using ctype to cast things? I feel like there is a good article that I have failed to come across and any direction would be great. Would a good approach to be to rewrite a program that is written with option strict off and note differences?

• Teaching myself, as a physicist, to become a better programmer

  - by user787267

  I've always liked physics, and I've always liked coding, so when I got the offer for a PhD position doing numerical physics (details are not relevant, it's mostly parallel programming for a cluster) at a university, it was a no-brainer for me. However, as most physicists, I'm self taught. I don't have broad background knowledge about how to code in an object oriented way, or the name of that specific algorithm that optimizes the search in some kD tree. Since all my work so far has been more concerned about the physics and the scientific results, I undoubtedly have some bad habits - more so because my coding is my own, and not really teamwork. I have mostly used C since it is very straightforward and "what you write is what you get" - no need for fancy abstractions. However, I have recently switched to C++ since I'd like to learn more about the power that comes with abstraction, and it's pretty C-like (syntax-wise at least). How do I teach myself to code in a good, abstract way like a graduate in computer science? I know my code is efficient, but I want it to be elegant as well, and readable. Keep in mind that I don't have time to read several 1000-page tomes about abstract programming. I need to spend time on actual, physics related research (my supervisor would laugh at me if he knew I spent time thinking about how to program elegantly). How do I assess if my work is also good from a programmer's perspective?

• Are there any companies using BDD in a .NET environment?

  - by Nick

  I've seen BDD in action (in this case using SpecFlow and Selenium in a .NET environment) for a small test project. I was very impressed - mainly due to the fact that the language used to specify the acceptance tests meant they engaged with the product owner much more easily. I'm now keen to bring this into my current organisation. However I'm asked 'who else uses this?' and 'show me some case-studies'. Unfortunately I cannot find any 'big names' (or even 'small names' for that matter!) of companies who are actively using BDD. I have two questions really: Is BDD adopted by companies out there? Who are they? How can BDD be implemented in an agile .NET environment and are there any significant drawbacks to doing it?

• How do you safely work around broken code? [closed]

  - by burnt1ce

  Once in a while, a co-worker will check-in bad code which blocks my application from initializing properly. To get around this problem quickly, I comment out the offending code. I then forget to uncomment the offending code at the time of my check-in, so I want to prevent this from happening again. Do you have any suggestions on how to: Disable bad code that stop you from working Prevent yourself from checking in unwanted changes? I'm currently using Visual Studio as my IDE and TFS as my source code repo.

• Resources for Test Driven Development in Web Applications?

  - by HorusKol

  I would like to try and implement some TDD in our web applications to reduce regressions and improve release quality, but I'm not convinced at how well automated testing can perform with something as fluffy as web applications. I've read about and tried TDD and unit testing, but the examples are 'solid' and rather simple functionalities like currency converters, and so on. Are there any resources that can help with unit testing content management and publication systems? How about unit testing a shopping cart/store (physical and online products)? AJAX? Googling for "Web Test Driven Development" just gets me old articles from several years ago either covering the same examples of calculator-like function or discussions about why TDD is better than anything (without any examples).

• When does 'optimizing code' == 'structuring data'?

  - by NewAlexandria

  A recent article by ycombinator lists a comment with principles of a great programmer. #7. Good programmer: I optimize code. Better programmer: I structure data. Best programmer: What's the difference? Acknowledging subjective and contentious concepts - does anyone have a position on what this means? I do, but I'd like to edit this question later with my thoughts so-as not to predispose the answers.

• File Upload Forms: Security

  - by Snow_Mac

  SO I'm building an application for uploading files. We're paying scientists to contribute information on pests, diseases and bugs (for Plants). We need the ability to drag and drop a file to upload it. The question becomes since the users will be authicentated and setup by us, will it be necessarcy to include a virus scanner to prevent the uploading and insertition of malicious files. How important is this?

• How to introduce versioning for questions on Stack*? [closed]

  - by András Szepesházi

  What today is the best answer for any given question, yesterday was not available and tomorrow will be obsolete. Especially when we're talking about software development. Here is an example for you (there must be thousands, this one is absolutely imaginary): Q: What is the best way to implement autocomplete in javascript? A: (2000) Whut? A: (2007) Write a custom ajax function, display the results after processing A: (2011) Use this plugin: http://jqueryui.com/demos/autocomplete/ (nono, I'm not a jQuery affiliate, actually I prefer MooTools) What would be your recommendation to introduce versioning for Stack Exchange questions and answers? Is there a need at all for that?

• Social Analytics in your current data

  - by Dan McGrath

  By now everyone is aware of the massive boom in social-networking (Twitter, Facebook, LinkedIn) and obviously a big part of its business model revolves around being able to mine this data to create information that can be used to make money for someone. Gartner has identified 'Social Analytics' as one of the top 10 strategic technologies for 2011. Has anyone looked at their existing data structures to determine if they could extract a social graph and then perform further data mining against this? How does it fit in with your other strategic development strategies? What information are you trying to extract from the data? Take for example, a bank. They could conceivably determine a social graph through account relationships and transactions. Obviously there would be open edges on the graph where funds enter/leave the institute, but that shouldn't detract from the usefulness of the data. I'm looking for actual examples with the answers, as well as why/how they did it. References to other sites will be greatly appreciated. Note: I'm not at all referring to mining data out of actual social networks.

• Bad style programming, am I pretending too much?

  - by Luca

  I realized to work in an office with a quite bad code base. The base library implemented in years and years is quite limited, and most of that code is, honestly, horrible. Projects developed in the office are very large. Fine. I could define me a "perfectionist" (but often I'm not), and I thought to refactor an application (really a portion), which need a new (complex) feature. But, today, I really realized that it's not possible to refactor that application modules with a reasonable time (say, 24/26 hours, respect the avaialable time for the task, which is 160 hours). I'm talking about (I am a bit ashamed to say) name collisions, large and frequent cut & paste code, horrible and misleading naming, makefiles without dependencies (!), application login is spread randomly across many different sources, dead code, variable aliasing, no assertion, no documentation, very long source files, bad/incomplete include file definition, (this is emblematic!) very frequent extern declaration of variables and functions, ... I'm sure to continue ... buffer overflows because sprintf, indentation (!), spacing, non existent const modifier usage. I would say that every source line was written quite randomly when needed, without keeping in mind some design (at least, the obvious one). (Am I in hell?) The problem arises when the application is developed by a colleague of mine. I felt very frustrated. So, I decided to expose the "situation" to my colleague; at the end, that was a bad idea. He is justified in saying that "the application was developed in haste, so it is natural that it is written vaguely; you are wasting time to think and implement an elegant implementation" .... I'm asking too much from my colleague to write readable code, which is managed and documented? I expect too much in not having to read thousands of lines of code to understand how a particular logic?

• New to Java and Spring. What are some good design principles for an inexperienced java developer like me?

  - by Imtiaz Ahmad

  I am learning Java and have written a few small useful programs. I am new to spring but have managed to understand the concept of dependency injection for decoupling. I'm trying to applying that in my development work in an enterprise setting. What are the 3 most important design patterns I should master (not for interview purposes but ones that I will use every day in as a good java developer)? Also what are some good java design considerations and practices in coding specifically in Java? My goal is write good decoupled and coherent programs that are easy to maintain that don't make me standout as a java rookie. Stuff like not beginning my package names with com. have already made me precariously visible in my team. But they know I have 2 years of coding experience and its not in java.

• data handling with javascript

  - by Vincent Warmerdam

  Python has a very neat package called pandas which allows for quick data transformation; tables, aggregation, that sort of thing. A lot of these types of functionality can also be found in the python itertools module. The plyR package in R is also very similar. Usually one woud use this functionality to produce a table which is later visualized with a plot. I am personally very fond of d3, and I would like to allow the user to first indicate what type of data aggregation he wants on the dataset before it is visualized. The visualisation in question involves making a heatmap where the user gets to select the size of the bins of the heatmap beforehand (I want d3 to project this through leaflet). I want to visually select the ideal size of the bins for the heatmap. The way I work now is that I take the dataset, aggregate it with python and then manually load it in d3. This is a process that takes a lot of human effort and I was wondering if the data aggregation can be done through the javascript of the browser. I couldn't find a package for javascript specifically built for data, suggesting (to me) that this is a bad idea and that one should not use javascript for the data handling. Is there a good module/package for javascript to handle data aggregation? Is it a good/bad idea to do the data aggregation in javascript (performance wise)?

• Why is there never any controversy regarding the switch statement? [closed]

  - by Nick Rosencrantz

  We all know that the gotostatement should only be used on very rare occasions if at all. It has been discouraged to use the goto statement countless places countless times. But why it there never anything like that about the switch statement? I can understand the position that the switch statement should always be avoided since anything with switch can always be expressed by if...else... which is also more readable and the syntax of the switch statement if difficult to remember. Do you agree? What are the arguments in favor of keeping the 'switch` statement? It can also be difficult to use if what you're testing changes from say an integer to an object, then C++ or Java won't be able to perform the switch and neither C can perform switch on something like a struct or a union. And the technique of fall-through is so very rarely used that I wonder why it was never presented any regret of having switch at all? The only place I know where it is best practice is GUI code and even that switch is probably better coded in a more object-oriented way.

• Who is Configuration Manager?

  - by altern

  I would like to ask members of the community about the role of Configuration Manager, as you see it. I'm not asking what Configuration Management is, as long it had been asked before. What I need to know is: What tasks do you think Configuration Manager should perform (or performs) in your team? What is primary responsibility of Configuration Manager? What are secondary/auxiliary responsibilities of Configuration Manager? Does Configuration Manager need to be in charge of development processes on the project/company or he should be told what to do? What are relations between Configuration Manager, Build Manager, Release Manager, Deployment Engineer, CI Engineer roles? Aren't they all the same - Configuration Management? Maybe term Configuration Management is redundant and Technical/Team Lead should do all the related work instead? It would be really great if you could share your vision and experience.

• Automated deployment/installation of development tools

  - by thegreendroid

  My team is looking to automate installation/deployment of all of our development tools. The main driver for this is to ensure that everyone in the team has a consistent development environment setup and to also allow a new recruit to get up and running easily. By development environment I mean tools like SCM, toolchains, IDEs etc. and by consistent I mean everyone using the same version of compiler to build code (this is very important!). Here are a few of our requirements – Allow unattended (silent) install of our entire dev setup by running a single script Ability to deploy selective updates (new versions) for specific tools Ability to report which tools are installed and their specific version numbers Must work on Windows (Linux would be a bonus) Must be easy to maintain What are some of the tools that you've used to automate such a task?

• Should I create my own Assert class based on these reasons?

  - by Mike

  The main reason I don't like Debug.Assert is the fact that these assertions are disabled in Release. I know that there's a performance reason for that, but at least in my situation I believe the gains would outweigh the cost. (By the way, I'm guessing this is the situation in most cases). And yes, I know that you can use Trace.Assert instead. But even though that would work, I find the name Trace distracting, since I don't see this as tracing. The other reason to create my own class is laziness I guess, since I could write methods for the most usual cases like Assert.IsNotNull, Assert.Equals and so forth. The second part of my question has to do with using Environment.FailFast in this class. Would that be a good idea? I do like the ideas put forth in this document. That's pretty much where I got the idea from. One last point. Does creating a design like this imply having an untestable code path, as described in this answer by Eric Lippert on a different (but related) question?

• Backend devs put down by user stories

  - by Szili

  I planned to slice in backend development into to the user stories vertically. But a backend guy on our team started to complain that this makes their work invisible. My answer was that at the sprint planning and review meetings we discuss backend tasks in front of stakeholders so it makes it visible, and maintaining a high quality during the project will result a slower startin pace than other teams, but we will have a stable velocity during the project. And velocity is highly visible to stakeholders. He still insist having stories like: "As a developer I need to have a domain layer so I can encapsulate business logic." How can I solve the issue before it pollutes the team? The root of the issue is that our management systematically consider backend work as invisible and call backed devs miners, or other pejorative terms.

• Useful certifications for a young programmer

  - by Alain

  As @Paddyslacker elegantly stated in Are certifications worth it? The main purpose of certifications is to make money for the certifying body. I am a fairly young developer, with only an undergraduate degree, and my job is (graciously) offering to sponsor some professional development of my choice (provided it can be argued that it will contribute to the quality of work I do for them). A search online offers a slew of (mostly worthless) certifications one can attain. I'm wondering if there are any that are actually recognized in the (North American) industry as an asset. My local university promoted CIPS (I.S.P., ITCP) at the time I was graduating, but for all I can tell it's just the one that happened to get its foot in the door. It's certainly money grubbing - with a $205 a year fee. So are there any such certifications that provide useful credentials? To better define 'useful' - would it benefit full time developers, or is it only something worth while to the self-employed? Would any certifications lead me to being considered for higher wages, or can that only be achieved with more experience and an higher-level degree?

• Moving Forward with Code Iteration

  - by rcapote

  There are times when working on my programming projects, and I get to a point where I'm ready to move on to the next part of my program. However, when I sit down to implement this new feature I get stuck, in a sense. It's not that I don't know how to implement the feature, it's that I get stuck on figuring out the best way to implement said feature. So I sit back for a day or two and let the ideas ferment until I am comfortable with a design. I get worried that I may not write something as well as it could be, or that I might have to go back and rework the whole thing; so I put it off. This is a big reason why I've never really finished many personal projects. Anyone else experience this, and how do you keep your self moving forward in your project?

• Intellectual Property for in house development

  - by Kyle Rogers

  My company is a sub contractor on a major government contract. Over the past 5 years we've been developing in house applications to help support our company and streamline our work. Apparently in 2008 our president of the company at that time signed a continuation of services contract with the company we subcontract with on this project. In the contract amendment various things were discussed such as intellectual property and the creation of new and existing tools. The contract states that all the subcontractor's tools/scripts/etc... become the intellectual property of the main contractor holder. Basically all tools that were created in support of the project which we work on are no longer ours exclusively and they have rights to them. My company really doesn't do software development specifically but because of this contract these tools helped tremendously with our daily tasking. Does my company have any sort of recourse or actions to help keep our tools? My team of developers were completely unaware of any of these negotiations and until recently were kept in the dark about the agreements that were made. Do we as developers have any rights to the software? Since our company is not a software development shop, we have created all these tools without any sort of agreements or contracts within the company stating that we give our company full rights to our creations? I was reading an article by Joel Spolsky on this topic and was just wonder if there is any advice out there to help assist us? Thank you Joel Spolsky's Article

• Why (not) logic programming?

  - by Anto

  I have not yet heard about any uses of a logical programming language (such as Prolog) in the software industry, nor do I know of usage of it in hobby programming or open source projects. It (Prolog) is used as an academic language to some extent, though (why is it used in academia?). This makes me wonder, why should you use logic programming, and why not? Why is it not getting any detectable industry usage?

• Where can I start learning to build web applications in C#

  - by Carson Myers

  So far I've written web sites in PHP, except for a pet project of mine written in Python. I'd like to start learning C# for use on the web, but I have no idea where to start. I know nothing of .Net. Are there any good tutorials or online books etc. which give a brief intro to the .Net environment (specifically C#, and specifically for the web)? I'm not even sure what I need to install. Visual Studio I guess, but what else? Anything special, or will VS do the trick?

• What kind of specific projects can I do to master bitwise operations in C++? Also is there a canonical book? [closed]

  - by Ford

  I don't use C++ or bitwise operations at my current job but I'm thinking of applying to companies where it is a requirement to be fluent with them (on their tests anyway). So my question is: Can anyone suggest a project which will require gaining a fluency in bitwise operations to complete? On a side note, is there a canonical book on optimization techniques using bitwise operations since that seems to be an important use of them?

• Multithreaded UI desktop application issues

  - by igor

  I am involved into development a rich UI project: desktop windows application. Application uses asynchronous invocations and in its turn it should be ready to process external messages (events). The problem is clear: at first time it was built as a simple prototype and it was not stress tested and all was fine. Then application was grown: the number of calls to server and number of events from server are high and performance is low. What is more users noticed that sometimes performance is extremal low. Asynchronous invocations based on thread pool (BeginInvoke, EndInvoke), external events are going from WCF service (.NET 3.5). My goal is synchronization of all tasks and putting priorities to every executions in desktop application. My question is: is there any practice how to reach my goal: patterns, task priority list, others? What should I do at first, second and next times? Thanks
