• Does TDD lead to the good design?

  - by Eugen Martynov

  I'm in transition from "writing unit tests" state to TDD. I saw as Johannes Brodwall creates quite acceptable design from avoiding any of architecture phase before. I'll ask him soon if it was real improvisation or he had some thoughts upfront. I also clearly understand that everyone has experience that prevents to write explicit design bad patterns. But after participating in code retreat I hardly believe that writing test first could save us from mistakes. But I also believe that tests after code will lead to mistakes much faster. So this night question is asking for people who is using TDD for a long time share their experience about results of design without upfront thinking. If they really practice it and get mostly suitable design. Or it's my small understanding about TDD and probably agile.

• Can't install fglrx on Kernel 3.11.0-12

  - by byf-ferdy

  I'm running Ubuntu Gnome 13.10 on a Sony Vaio laptop. I tried to install the newest fglrx driver from the cchtml.com guide but no matter which version I use (13.4 or even 13.9) the installation of the generated .debs fails with this message: Error! Bad return status for module build on kernel: 3.11.0-12-generic (x86_64) This seems to be a confirmed bug on launchpad. Currently I'm running the Radeon SI driver but I really need some 3D acceleration. What is there I can do to install any version of fglrx correctly or to speed up the bug-fixing-process? How long does the fixing of these bugs usually take?

• Do private static methods in C# hurt anything?

  - by fish

  I created a private validation method for a certain validation that happens multiple times in my class (I can't store the validated data for various reasons). Now, ReSharper suggests that the function could be made static. I'm a little reluctant to do so due known problems with static methods. It would be a private static method. My question is, can private static methods cause similar coupling and testing problems like public static methods? Is it a bad practice? I would guess not, but I'm not sure if there is a pitfall here.

• Make game for iPhone only

  - by Alex

  From the beginning of development on my game I was hoping to release it as a universal app, but the gameplay simply doesn't work as well on the iPad. Also, it was designed to work on the iPhone screen, and the (even slight) difference in width to height ratio gives iPhone users an advantage over iPad users by seeing more of the path ahead. Not to mention it doesn't look quite right on the larger screen. Hypothetically, if my game becomes a top seller, would it be a bad idea to have it only an iPhone app? Would it make it far less likely for my app to become viral? My app would still work on the iPad like any other iPhone app, and I plan on eventually releasing an update that supports both iPad and iPhone.

• Why has C prevailed over Pascal?

  - by Konrad Morawski

  My understanding is that in the 1980s and perhaps in the 1990s, too - Pascal and C were pretty much head-to-head as production languages. Is the ultimate demise of Pascal only due to Borland's neglection of Delphi? Or was there more of such bad luck; or perhaps something inherently wrong with Pascal (any hopes for its revival?). I hope it's not an open, unanswerable question. I'm interested in historical facts and observations one can back up, rather than likes and dislikes. I also failed to find a duplicate question, which actually surprised me somewhat.

• Using GParted to rescue data and format hard drive to NTFS

  - by Ishan

  I'm having problems booting to Windows XP due to bad sectors on the hard drive. I've tried fixboot and fixmbr from the recovery console. That only made matters worse. Now I want to use GParted to attempt data rescue and format the hard drive to NTFS. Unfortunately, I get an error (Picture 2) when trying to recover my files, and the option to format the hard drive is grayed out. The only thing I can do is create a new partition. When I click "view" I get the "Unable to open the default file manager" error

• RPi and Java Embedded GPIO: Sensor Hardware for Java Enabled Interface

  - by hinkmond

  Now here's the hardware you'll need to make a Java app interface with a static charge sensor connected to your Raspberry Pi via the GPIO port. It means another Fry's run of course. That's not too bad during Christmas since you can browse all the gadget and toys while doing your shopping for sensor hardware for your RPi. Here's a your shopping list: 1 - NTE312 JFET N-channel transistor (this is in place of the MPF-102) 1 - Set of Jumper Wires 1 - LED 1 - 300 ohm resistor 1 - set of header pins Grab all that from Fry's or your local hobby electronics shop and come back here for how to connect it together. Oh, and don't go too crazy buying all the other electronic toys and gadgets that catch your eye because of the holiday displays at the store. Hinkmond

• How do I add a network printer in Ubuntu 12.04?

  - by Ricky Robinson

  I know the name and the IP address of a network printer, but I can't seem to be able to search by IP address or name. Ubuntu developers love to move things around to make it difficult for users, so now with Ubuntu 12.04 I can only go on Application -> System Tools -> System Settings -> Printers, click on Network and a list of printers appears. Too bad the one I want to add isn't there. How do I do it? Here it suggests System -> Administration -> Printing, which simply doesn't exist.

• Best way to relate code smells to a non technical audience?

  - by Ed Guiness

  I have been asked to present examples of code issues that were found during a code review. My audience is mostly non-technical and I want to try to express the issues in such a way that I convey the importance of "good code" versus "bad code". But as I review my presentation it seems to me I've glossed over the reasons why it is important to write good code. I've mentioned a number of reasons including ease of maintenance, increased likelihood of bugs, but with my "non tech" hat on they seem unconvincing. What is your advice for helping a non-technical audience relate to the importance of good code?

• anxiety and programming [closed]

  - by user83379

  I went to the doctor for anxiety and was prescribed a small dose of lexapro to help with anxiety and sleeping better. I am cautious about taking it since this is the first time it's got bad enough for me to talk to someone and I'm concerned it may negatively impact my career as a software developer. I'm also afraid that once I start it may be difficult to come off. Does anyone on here have experience with this? Is it likely that taking lexapro would negatively affect my problem solving skills, passion for programming or job performance? Thanks for any suggestions.

• Typing tutor games with good playablity

  - by matt wilkie

  Are there any linux typing tutor games which are enjoyable games in their own right? I'm a computer professional, but have never learned to type properly. I also don't want my kids to pick up my bad habits! The kids are okay with TuxTyping, for a time. Something like Typing of the Dead sounds great, but is Windows only, and as far as I can tell one of a kind. I also don't want the young'uns hooked on first person shooters just yet. So are there any quality typing games for a range of ages?

• How to use multiple monitors effectivelly

  - by maaartinus

  I'm currently using a single monitor, since I see no value in something like this mentioned in this answer. It may be a good exercise for my neck, but besides of this I see no use therein at all. This amounts to 5760x1200 pixels, which is nearly 7M pixels, just fantastic, except for me not being a cyklop-han. The ratio of 24:5 is IMHO too bad for this to be usable. I don't even think that two 16:10 monitors side by side is a good idea. I never tried so I may be completely wrong, but I suppose that the 4:3 ratio would be much better for this. Or even 1:1, but no such thing is available (with some exceptions, either very expensive or very low resolution). Does anybody use two monitors arranged vertically (resulting in 16:20)? or two pivoted monitors side by side (resulting in 20:16)? or another such variant?

• Algorithm to reduce a bitmap mask to a list of rectangles?

  - by mos

  Before I go spend an afternoon writing this myself, I thought I'd ask if there was an implementation already available --even just as a reference. The first image is an example of a bitmap mask that I would like to turn into a list of rectangles. A bad algorithm would return every set pixel as a 1x1 rectangle. A good algorithm would look like the second image, where it returns the coordinates of the orange and red rectangles. The fact that the rectangles overlap don't matter, just that there are only two returned. To summarize, the ideal result would be these two rectangles (x, y, w, h): [ { 3, 1, 2, 6 }, { 1, 3, 6, 2 } ]

• Best way to go about sorting 2D sprites in a "RPG Maker" styled RPG

  - by Aaron Stewart

  I am trying to come up with the best way to create overlapping sprites without having any issues. I was thinking of having a SortedDictionary and setting the Entity's key to it's Y position relative to the max bound of the simulation, aka the Z value. I'd update the "Z" value in the update method each frame, if the entity's position has changed at all. For those who don't know what I mean, I want characters who are standing closer in front of another character to be drawn on top, and if they are behind the character, they are drawn behind. I'm leery of using SpriteBatch back to front or front to back, I've been doing some searching and have been under the impression they are a bad idea. and want to know exactly how other people are dealing with their depth sorting. Just ultimately trying to come up with the best method of sorting for good practice before I get too far in to refactor the system effectively.

• Mobile miscellany; 14 April

  Some updates on a few developing stories in the mobile space. First of all, the Palm acquisition. Right now the chaos is only increasing. Mobile consultant Tomi Ahonen gives an excellent overview of all major mobile players and why they would want to acquire Palm — or not. His bet is on Lenovo, with HTC running second. See also this piece which pinpoints Palm’s distribution model (or rather lack thereof) as a serious problem. The Sprint-exclusivity in the US was a bad idea. Meanwhile, Huawei and...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

• Death March

  - by Nick Harrison

  It is a horrible sight to watch a project fail. There are few things as bad. Watching a project fail regardless of the reason is almost like sitting in a room with a "Dementor" from Harry Potter. It will literally suck all of the life and joy out of the room. Nearly every project that I have seen fail has failed because of political challenges or management challenges. Sometimes there are technical challenges that bring a project to its knees, but usually projects fail for less technical reasons. Here a few observations about projects failing for political reasons. Both the client and the consultants have to be committed to seeing the project succeed. Put simply, you cannot solve a problem when the primary stake holders do not truly want it solved. This could come from a consultant being more interested in extended the engagement. It could come from a client being afraid of what will happen to them once the problem is solved. It could come from disenfranchised stake holders. Sometimes a project is beset on all sides. When you find yourself working on a project that has this kind of threat, do all that you can to constrain the disruptive influences of the bad apples. If their influence cannot be constrained, you truly have no choice but to move on to a new project. Tough choices have to be made to make a project successful. These choices will affect everyone involved in the project. These choices may involve users not getting a change request through that they want. Developers may not get to use the tools that they want. Everyone may have to put in more hours that they originally planned. Steps may be skipped. Compromises will be made, but if everyone stays committed to the end goal, you can still be successful. If individuals start feeling disgruntled or resentful of the compromises reached, the project can easily be derailed. When everyone is not working towards a common goal, it is like driving with one foot on the break and one foot on the accelerator. Not only will you not get to where you are planning, you will also damage the car and possibly the passengers as well.   It is important to always keep the end result in mind. Regardless of the development methodology being followed, the end goal is not comprehensive documentation. In all cases, it is working software. Comprehensive documentation is nice but useless if the software doesn't work.   You can never get so distracted by the next goal that you fail to meet the current goal. Most projects are ultimately marathons. This means that the pace must be sustainable. Regardless of the temptations, you cannot burn the team alive. Processes will fail. Technology will get outdated. Requirements will change, but your people will adapt and learn and grow. If everyone on the team from the most senior analyst to the most junior recruit trusts and respects each other, there is no challenge that they cannot overcome. When everyone involved faces challenges with the attitude "This is my project and I will not let it fail" "You are my teammate and I will not let you fail", you will in fact not fail. When you find a team that embraces this attitude, protect it at all cost. Edward Yourdon wrote a book called Death March. In it, he included a graph for categorizing Death March project types based on the Happiness of the Team and the Chances of Success.   Chances are we have all worked on Death March projects. We will all most likely work on more Death March projects in the future. To a certain extent, they seem to be inevitable, but they should never be suicide or ugly. Ideally, they can all be "Mission Impossible" where everyone works hard, has fun, and knows that there is good chance that they will succeed. If you are ever lucky enough to work on such a project, you will know that sense of pride that comes from the eventual success. You will recognize a profound bond with the team that you worked with. Chances are it will change your life or at least your outlook on life. If you have not already read this book, get a copy and study it closely. It will help you survive and make the most out of your next Death March project.

• Books for MCSD and advice

  - by Mahesha999

  Hi there I am thinking to get certification done for MCSD. http://www.microsoft.com/learning/en/us/certification/cert-mcsd-web-applications.aspx I did found the books for first exam 480 comprising CSS3, HTML5 and JavaScript. However I did not found books for other exams: 486: ASP.NET MVC 4.5 Apps - Will ASP.NET 4 books suffice for this? Should I also learn Web Forms though I have considerable part of it. 487: Windows Azure and Web Services - What book should I use? I seems that the syllabus is too huge and will take considerable time. Anyone suggesting any advice to complete such exams, since this is going to be my first such. How should I prepare? Should I give this exam? Will it help? Sorry I know I asked many questions here in one questions - a bad practice but the books-question is a big concern for me.

• Redirect from https://mydomain.com to http://mydomain.com

  - by Charlie

  Many of my visitors have bookmarked my site already wtih https://mydomain.com. Under the bad advice of a programmer, I put my whole Joomla site under ssl. I do not sell anything or provide any member services. I asked him many times if it would slow my site down - he said it wouldn't. I knew it did, I've researched on this site and realized it does slow the site down because of no cache of the pages. Understood. Please, someone tell me how to get away from it now. I'm not sure how to approach this, should I add something to my htaccess or my main index.php file? I've looked all over the net, there is much advice for adding redirectives for going from http to https, but very few answers regarding the opposite of going from https to http. Thank you very much for your time. I appreciate it.

• How to price code reviews to encourage good behavior?

  - by Chris Clark

  I work for a company that has a hosted .net internet application with many clients. Those clients often want to write customizations for our application. We have APIs to hook into the app, but the customizations themselves are written in .net. This is a shared, secure hosting environment and we have to code review these customizations before we can deploy them in our datacenter to ensure that they don't degrade performance, crash our servers, or open any security vulnerabilities. We charge for these code reviews. The current pricing model is simply a function of the number of lines of code. I think this is a bad idea for a variety of reasons, but primarily because, if we are interested in verifying that the code works as expected, we should be incentivizing good, readable code, not compaction. I would like to propose a pricing model that incorporates some, or all of the following as inputs: Lines of code Cyclomatic complexity Avg function length # of functions Are there any other metrics I should incorporate, or other ideas for how we can reasonably create pricing for code reviews that encourages safe and understandable code?

• Java regex patterns - compile time constants or instance members?

  - by KepaniHaole

  Currently, I have a couple of singleton objects where I'm doing matching on regular expressions, and my Patterns are defined like so: class Foobar { private final Pattern firstPattern = Pattern.compile("some regex"); private final Pattern secondPattern = Pattern.compile("some other regex"); // more Patterns, etc. private Foobar() {} public static Foobar create() { /* singleton stuff */ } } But I was told by someone the other day that this is bad style, and Patterns should always be defined at the class level, and look something like this instead: class Foobar { private static final Pattern FIRST_PATTERN = Pattern.compile("some regex"); private static final Pattern SECOND_PATTERN = Pattern.compile("some other regex"); // more Patterns, etc. private Foobar() {} public static Foobar create() { /* singleton stuff */ } } The lifetime of this particular object isn't that long, and my main reason for using the first approach is because it doesn't make sense to me to hold on to the Patterns once the object gets GC'd. Any suggestions / thoughts?

• With a small development team, how do you organize second-level support?

  - by Lenny222

  Say, you have a team of 5 developers and your inhouse customers demand a reasonable support availability of say 5 days a week, 9am-6pm. I can imagine the following scenarios: the customers approach the same guy, every time. Downside: single point of failure, if the guy is unavailable. each developer is assigned one week of support duty. Downside: how to you distribute the work evenly in times of planned (vacation) and unplanned (sickness) unavailability? each developer is assigned one day of support duty. Downside: similar to above, but not as bad. a randomly picked developer handles the support request. Downside: maybe not fair, see above. What is your experience?
