  • Should we test all our methods?

    - by Zenzen
    So today I had a talk with my teammate about unit testing. The whole thing started when he asked me "hey, where are the tests for that class, I see only one?". The whole class was a manager (or a service if you prefer to call it like that) and almost all the methods were simply delegating stuff to a DAO so it was similar to: SomeClass getSomething(parameters) { return myDao.findSomethingBySomething(parameters); } A kind of boilerplate with no logic (or at least I do not consider such simple delegation as logic) but a useful boilerplate in most cases (layer separation etc.). And we had a rather lengthy discussion whether or not I should unit test it (I think that it is worth mentioning that I did fully unit test the DAO). His main arguments being that it was not TDD (obviously) and that someone might want to see the test to check what this method does (I do not know how it could be more obvious) or that in the future someone might want to change the implementation and add new (or more like "any") logic to it (in which case I guess someone should simply test that logic). This made me think, though. Should we strive for the highest test coverage %? Or is it simply an art for art's sake then? I simply do not see any reason behind testing things like: getters and setters (unless they actually have some logic in them) "boilerplate" code Obviously a test for such a method (with mocks) would take me less than a minute but I guess that is still time wasted and a millisecond longer for every CI. Are there any rational/not "flammable" reasons to why one should test every single (or as many as he can) line of code?

  • Is chroot the right choice for my use case?

    - by Anthony
    Backstory: I am working on setting up a MineCraft server and want to allow admins to have ssh access to the MineCraft server console and appropriate mc server files, but not the whole system. The console provided by the minecraft server is only available to the user that launched the process. In addition, the admins will need terminal access to some basic cli tools such as wget, cp, mv, rm, and a text editor. Plan: I have already setup the ssh aspect of things, requiring pre-shared keys and whatnot. Setup a jailed environment in which all user activity will be contained. Setup user accounts. - The first user account will be the minecraft user. The minecraft user will start the MC server in a multiuser screen session and allow the other admins to attach to it. - Subsequent users should have their own /home directory for normal usage. Setup acl for the appropriate files to allow each user to edit the mc server files. No one will be doing system updates, nor will anyone be installing any programs, so I'll be the only user with sudo. The Issues: I don't want the ssh users to have access to the whole system. Users will still need to use wget or curl to update the mc server files. Is chroot the right tool for this use case, or is there something more appropriate for the job? I have no experience setting up a chroot environment and have found several tools to aid in this process. Jailkit seems to be the most robust, but it's not in the standard repos.

  • Dualboot Asus n56v (ubuntu / win 7 x64) - ubuntu doesn't detect partition table made by windows

    - by user76439
    I have an Asus n56v and I've got troubles installing Ubuntu 12.04 x64. I already have installed Windows 7 x64! The hard drive is: Hitachi HTS547575A9E384 My problem: The installation program doesn't recognize the already existing partitions and is offering only options where there are partitions. Can someone help me out? Is this an ACPI/IDE conflict, missing driver or conflict with Windows 7? (I'm not an expert on Linux, only working sometimes with it.) I now tried out some options concerning EFI with a GTP-table. Everything worked but I wasn't able to fix a dual boot (Windows boot loader) nor with GRUB2. The laptop is still having a BIOS, but is able to boot DVDs/CDs in EFI-mode. Now I try to avoid EFI and GTP using the old windows MBR style. I reinstalled Windows, so far no problem. When I want to try to install Ubuntu, it doesn't detect the already existing partition table. It is just showing me an empty space for the whole disk. Other threads like Ubuntu 12.04 does not see windows already install on my computer (dual installation) don't help me out. os-prober shows me a correct result. I don't know how to deal with gdisk as shown in Installer doesn't detect existing partition table/windows 7 partition. I have 750GB for the whole disk. I'm using: 90GB for Windows reserved partition + system partition, 500GB for data and the rest should be for SWAP and linux-system. How can I make Ubuntu detect the partition table?

  • Pure functional programming and game state

    - by Fu86
    Is there a common technique to handle state (in general) in a functional programming language? There are solutions in every (functional) programming language to handle global state, but I want to avoid this as far as I could. All state in a pure functional manner are function parameters. So I need to put the whole game state (a gigantic hashmap with the world, players, positions, score, assets, enemies, ...)) as a parameter to all functions which wants to manipulate the world on a given input or trigger. The function itself picks the relevant information from the gamestate blob, do something with it, manipulate the gamestate and return the gamestate. But this looks like a poor mans solution for the problem. If I put the whole gamestate into all functions, there is no benefit for me in contrast to global variables or the imperative approach. I could put just the relevant information into the functions and return the actions which will be taken for the given input. And one single function apply all the actions to the gamestate. But most functions need a lot of "relevant" information. move() need the object position, the velocity, the map for collision, position of all enemys, current health, ... So this approach does not seem to work either. So my question is how do I handle the massive amount of state in a functional programming language -- especially for game development?

  • System in low graphics, deleted linux, grub rescue, can't access windows

    - by First timer
    So I'm pretty new to Ubuntu but I managed to install it with no big problems on both my desktop and netbook. When I installed it on my brother's netbook everything went horribly wrong and now I fear the system is close to beyond repair. The problem was first that it said it did not have any space left (seemed ridiculous since it had a lot). Then Ubuntu began booting into a "System is running in low graphics mode error" which I then tried to fix, using all the tips I could find in here but nothing helped. I think the graphics error and lack of space might have been related but I can't be sure. Finally I gave up repairing Ubuntu and went for a reinstall. Shouldn't have done that! I read that I should simply open Ubuntu through a live usb and choose GParted to delete the Linux partitions so I did and rebooted accordingly. Next, I was to install Ubuntu but now I am only given the option to wipe the whole disk for Ubuntu, not install along with windows 7. If I access GParted I can still see the ntfs partitions that hold windows 7 (there are 2: one labeled RECOVERY and another labeled OS and boot) so why can't I access them? Btw. the OS and boot has a little red mark with a warning that 1 cluster is referenced to multiple times, don't know what that means. If I boot without the live usb I am sent directly into a grub rescue "black screen of the computer will follow no orders". Please, I know that the easiest might be to simply wipe the whole thing clean but there are important files and programs on windows 7. Is there a way to just access windows? It is a dell inspiron 1018 mini netbook, so I have no cd input and no windows 7 installation cd.

  • When can I publish a software tool written at work?

    - by AlexMA
    I'm working on a software problem at work that is fairly generic, but I can't find a library I like to solve it, so I'm considering writing one myself (at least a bare-bones version). I'll be writing some if not all of the 1.0 version at work, since I need it for the project. If turns out well I might want to bring the work home and polish it up just for fun, and maybe release it as an open-source project. However, I'm concerned that if I wrote the 1.0 version at work I may not be allowed to do this from a legal sense. Obviously I could ask my boss (who probably won't care), but I'm curious how other programmers have dealt with this issue and where the law stands here. My one sentence question is, When is it okay (legally/ethically) to open-source a software tool originally written by you for work at work? What if you have expanded the original source significantly during off-hours? Follow-up: Suppose I write the whole thing at home on my time then simply use it at work, does that change things drastically? Follow-up 2: Note that I'm not trying to rip off my employer (I understand that they're paying me to build products that they own)--I'm just wondering if there's a fair way of doing this for all involved... It would be nice if some nonprofit down the road could use my code and save them some time. Also, there's another issue at stake. If I write the library for a very simple, generic thing (like HTML tables in Javascript), does that mean I can never again do so on my own time without putting myself at legal risk (even if it was a whole new fresh rewrite or a segment of a larger project). Am I surrendering my right to write code for this sort of project for the rest of my life (without this company's permission), since the code at work might still be somewhere in my brain influencing me? This seems related to software patents, as a side-note.

  • Cloud Computing - just get started already!

    - by BuckWoody
    OK - you've been hearing about "cloud" (I really dislike that term, but whatever) for over two years. You've equated it with just throwing some VM's in some vendor's datacenter - which is certainly part of it, but not the whole story. There's a whole world of - wait for it - *coding* out there that you should be working on. If you're a developer, this is just a set of servers with operating systems and the runtime layer (like.NET, Java, PHP, etc.) that you can deploy code to and have it run. It can expand in a horizontal way, allowing massive - and I really, honestly mean massive, not just marketing talk kind of scale. We see this every day. If you're not a developer, well, now's the time to learn. Explore a little. Try it. We'll help you. There's a free conference you can attend in November, and you can sign up for it now. It's all on-line, and the tools you need to code are free. Put down Facebook and Twitter for a minute - go sign up. Learn. Do. :) See you there. http://www.windowsazureconf.net/

  • When NOT to use a framework

    - by Chris
    Today, one can find a framework for just about any language, to suit just about any project. Most modern frameworks are fairly robust (generally speaking), with hour upon hour of testing, peer reviewed code, and great extensibility. However, I think there is a downside to ANY framework in that programmers, as a community, may become so reliant upon their chosen frameworks that they no longer understand the underlying workings, or in the case of newer programmers, never learn the underlying workings to begin with. It is easy to become specialized to a degree that you are no longer a 'PHP programmer' (for example), but a "Drupal programmer", to the exclusion of anything else. Who cares, right? We have the framework! We don't need to know how to "do it by hand"! Right? The result of this loss of basic skills (sometimes to the extent that programmers who don't use frameworks are viewed as "outdated") is that it becomes common practice to use a framework where it is not required or appropriate. The features the framework facilitates wind up confused with what the base language is capable of. Developers start using frameworks to accomplish even the most basic of tasks, so that what once was considered a rudimentary process now involves large libraries with their own quirks, bugs, and dependencies. What was once accomplished in 20 lines is now accomplished by including a 20,000 line framework AND writing 20 lines to use the framework. Conversely, one does not want to reinvent the wheel. If I'm writing code to accomplish some basic, common little task, I might feel like I am wasting my time when I know that framework XYZ offers all the features I am after, and a whole lot more. The "whole lot more" part still has me worried, but it doesn't seem that many even consider it anymore. There has to be a good metric to determine when it is appropriate to use a framework. What do you consider the threshold to be, how do you decide when to use a framework, or, when not.

  • How do I get a different type of scrollbars in 12.04? [closed]

    - by Joseph Garvin
    Possible Duplicate: How do I disable overlay scrollbars? By default 12.04 uses overlay scroll bars that do not suit my taste, and every method I've found so far of disabling them makes them broken in a different way. When I was using 11.10 this wasn't a problem because I could still change the GTK theme. In 12.04, the Appearance settings only contain a few stock themes, and other than the special purpose contrast ones they all have the overlay scroll bars. If I aptitude search gtk3 | grep theme I get no results so there appears to be no packaged alternative either. Most suggestions I've seen for disabling the overlay scroll bars involve uninstalling packages or editing files as root. I want to disable them just for the current user, not for everyone on the whole box; as should be the case for any theme/display setting. There is a gsettings command that temporarily disables the overlay scrollbars just for the current user, but this has two problems of its own: The setting doesn't stick after log off. Because who would want to save settings? The scroll bars put in place have no contrast. They have a black scroller on a black background and are completely unusable. In short what I'd like to know is how to disable overlay scroll bars such that: My preference is user specific. My preference is actually saved. The scroller can actually be seen against the background without having to use a special high contrast theme that makes my whole desktop look like a negative photo from Tron.

  • Career change: from programming into more human-oriented area [closed]

    - by Art
    I have been a software developer for approximately 9 years, starting with part-time work during my graduation year at uni. During these years I worked for number of companies, sometimes changing places twice or three times a year. They say it takes 10 years to reach 'expert' level, and while I don't think I am an expert by any measure and I have certainly met lots of people who are more knowledgeable, smarter and more focused than I am, I think I can safely say that I had my fair share of the whole programming trade and would like to move on to something else. Psychology and behaviour was always something I was interested in, especially the practical, applicable bits of it. Recently I've been to some communication skills training and I realised that I have been missing out on the great deal of fun stuff - how people work and communicate, especially in subconscious, non-verbal area. Currently I am thinking of making a career change - ideally to move somewhere my technical skill would still be beneficial in some shape or form, or at least could serve as a bridge while I am transitioning there, you know, the whole gradual, bit-by-bit approach versus swim-or-drown one. I would like to hear your thoughts on this matter and to learn from you what are the possible transitions I can take.

  • Storage of leftover values in a situation of having to round down

    - by jt0dd
    I'm writing an app (client and server side) where the number of sales required by each employee must be kept track of in round-number form. Each month, the employees are required to sell a certain number, and this app needs to keep track of how many sales must be made for each 12 hour interval during the work week. Because I have to round the values down to a whole number, I must keep track of leftovers in the rounding process and ensure that they are always carried over. My method must ensure the storage of the leftover value even when client and server side crash, restart, close, etc. Right now, I'm working on doing this by storing the leftovers in a field in the user's account row in the database each time a value is rounded, reading the stored value, removing any portion that is used (when a whole number is reached, most of the leftover is used up), and storing the new value. This practice seems weird because while the leftovers are calculated on the client side, it's the same number for each employee, and every employee using the app is storing a copy of the same leftover data. Alternatively, I could have all clients store the data at once into the same data field on a general table, but this is just as weird. Is there a better way that this can be handled or is my method correct?

  • Finding back to an old project that was turned upside-down by the developer. Your workflow?

    - by Kreativrandale
    after some time I'm asked to work on a heavy web-project I did (layout, html/css) about a year ago. There are some changes that have to be made, basically some css and js stuff. By now the whole project was turned upside down by the developer. It gives me a hard time to connect to the work of him, especially because my old files and file-structure won't work anymore. Thats why I need a up-to-date working-environment, but I don't want to change the files on the server directly. Need some testing and improving while doing this. So, what is your workflow in such a case? Thought about copying the whole/parts of the server to a own homeserver. But even that will be a big task for me (I'm more the front-end-guy). Would be great if theres a way to shrink it down (php, mysql,...), since I only need to change some css/html javascript. Are there any tools available? Love to hear how you handle such situations. Thanks a lot!

  • PyQt application architecture

    - by L. De Leo
    I'm trying to give a sound structure to a PyQt application that implements a card game. So far I have the following classes: Ui_Game: this describes the ui of course and is responsible of reacting to the events emitted by my CardWidget instances MainController: this is responsible for managing the whole application: setup and all the subsequent states of the application (like starting a new hand, displaying the notification of state changes on the ui or ending the game) GameEngine: this is a set of classes that implement the whole game logic Now, the way I concretely coded this in Python is the following: class CardWidget(QtGui.QLabel): def __init__(self, filename, *args, **kwargs): QtGui.QLabel.__init__(self, *args, **kwargs) self.setPixmap(QtGui.QPixmap(':/res/res/' + filename)) def mouseReleaseEvent(self, ev): self.emit(QtCore.SIGNAL('card_clicked'), self) class Ui_Game(QtGui.QWidget): def __init__(self, window, *args, **kwargs): QtGui.QWidget.__init__(self, *args, **kwargs) self.setupUi(window) self.controller = None def place_card(self, card): cards_on_table = self.played_cards.count() + 1 print cards_on_table if cards_on_table <= 2: self.played_cards.addWidget(card) if cards_on_table == 2: self.controller.play_hand() class MainController(object): def __init__(self): self.app = QtGui.QApplication(sys.argv) self.window = QtGui.QMainWindow() self.ui = Ui_Game(self.window) self.ui.controller = self self.game_setup() Is there a better way other than injecting the controller into the Ui_Game class in the Ui_Game.controller? Or am I totally off-road?

  • Rendering multiple squares fast?

    - by Sam
    so I'm doing my first steps with openGL development on android and I'm kinda stuck at some serious performance issues... What I'm trying to do is render a whole grid of single colored squares on to the screen and I'm getting framerates of ~7FPS. The squares are 9px in size right now with one pixel border in between, so I get a few thousand of them. I have a class "Square" and the Renderer iterates over all Squares every frame and calls the draw() method of each (just the iteration is fast enough, with no openGL code the whole thing runs smootlhy at 60FPS). Right now the draw() method looks like this: // Prepare the square coordinate data GLES20.glVertexAttribPointer(mPositionHandle, COORDS_PER_VERTEX, GLES20.GL_FLOAT, false, vertexStride, vertexBuffer); // Set color for drawing the square GLES20.glUniform4fv(mColorHandle, 1, color, 0); // Draw the square GLES20.glDrawElements(GLES20.GL_TRIANGLES, drawOrder.length, GLES20.GL_UNSIGNED_SHORT, drawListBuffer); So its actually only 3 openGL calls. Everything else (loading shaders, filling buffers, getting appropriate handles, etc.) is done in the Constructor and things like the Program and the handles are also static attributes. What am I missing here, why is it rendering so slow? I've also tried loading the buffer data into VBOs, but this is actually slower... Maybe I did something wrong though. Any help greatly appreciated! :)

  • Incremental search in Visual Studio

    - by Jalpesh P. Vadgama
    Visual studio is a Great IDE and there are still lots of feature that not known to developers. Incremental search is one of them. This is a amazing feature to find code in particular document and its available from Visual Studio 2010 and carried over in Visual Studio 2012. Incremental search allows developers to search in document without blocking UI and allow to search as they type. Interesting!! right.. So let’s open visual studio and see how it works. Once you open Visual Studio and press Ctrl + I and type something it will find the string without blocking your visual studio UI. Just like following. In the above code you can see that, I have typed Cons and You can see that whole console word is highlighted. Even you can see that find dialog box on top right corner of visual studio 2012 like following. Same way if you see the footer in visual studio where it is finding cons in current document like following. Isn’t that great now we find things very easily and we don’t have to remember whole word like Console. Hope you like it. Stay tuned for more updates.

  • Eclipse will not install Android Support Package [migrated]

    - by Michael Mossman
    I am an experienced programmer but new to Android, hence using Eclipse for the first time. Unfortunately I cannot get my first project off the ground. I get as far trying to create the project when the following sequence happens. A screen arrives titled 'Install Dependencies' telling me that the required version is 8 and the installed version is 'Not installed' I click on the Install/Upgrade button and something must happen because Android SDK Manager pops up and I get a whole series of 'Fetching:' messages. The next screen asks me to Choose Package to Install and the only option is Android Support Library, revision 10. This doesn't bother me as I presume 10 is better than 8 so I hit the Install button. This is where it all goes wrong as I get a red message saying: File not found: C:\Program Files (X86)\Android\android-sdk\temp\support_r10.zip (Access is denied). Sure enough, when I check this folder, it is empty. Now, something must have happened as as SDK Manager did a whole lot of fetching and must have put these files somewhere. I am quite happy to find them and put them in the correct folder but the question is what is the name of the files that I am looking for?

  • how do I fix 12.04 which has crashed after the latest update

    - by user70261
    I added a new drive to my system because the old one was full and stopped. I installed 12.04 at the same time, onto the new drive using a flash disk while off line. The system performs fine on 12.04 from the flash disk and it booted from the new drive OK and I was able to recover all my old data. The updater suggested that I update, so I went ahead and did so. At the end of which it wanted to reboot. I went ahead but on reboot I get to the log in prompt and then the whole system crashes. It tries to recover and then performs a bug report during which it tells me that a whole bunch of files are out of date (these would be the new ones I just updated!) and the screen goes black. Game over. I've tried to reboot several times ... same result. I can boot off the flash drive OK. How do I restore the system I had before the update, without over writing all my hard earned recovered data? Or how do I identify the "new updates" that are causing me grief?

  • Looking for algorithms regarding scaling and moving

    - by user1806687
    I've been bashing my head for the past couple of weeks trying to find algorithms that would help me accomplish, on first look very easy task. So, I got this one object currently made out of 5 cuboids (2 sides, 1 top, 1 bottom, 1 back), this is just for an example, later on there will be whole range of different set ups. I have included three pictures of this object(as said this is just for an example). Now, the thing is when the user scales the whole object this is what should happen: X scale: top and bottom cuboids should get scaled by a scale factor, sides should get moved so they are positioned just like they were before(in this case at both ends of top and bottom cuboids), back should get scaled so it fits like before(if I simply scale it by a scale factor it will leave gaps on each side). Y scale: sides should get scaled by a scale factor, top and bottom cuboid should get moved, and back should also get scaled. Z scale: sides, top and bottom cuboids should get scaled, back should get moved. Here is an image of the example object (a thick walled box, with one face missing, where each wall is made by a cuboid): Front of the object: Hope you can help,

  • 12.04 doesn't boot anymore after a power failure

    - by Felix
    I'm a Windows user and I have no experience with Linux and Ubuntu. I installed Ubuntu 12.04 on my netbook (Asus 1215B) and everything works fine. Yesterday I ran the "update application" and updated over 120 "things" (I have no idea what exactly). After that I was asked to reboot, and I did. Ubuntu starts again and at the load screen with these 5 dots that normally begin to change color, it freezes. After 20 minutes I took out the battery to try another reboot (yes, not the the best idea), and now nothing happens. I boot from the HDD and I get an Error BOOTMGR is missing. I have important data on the hard drive. Is there an option to get this fixed? Or if not, to at least get the data from the hard drive? Ubuntu 12.04 64-bit Edit: it is ONLY Ubuntu on this Netbook, which uses the whole 500gb HDD as 1 Partition. Filesystem is NTFS. Whole Hardware seems okay. The USB drive which i used to instl the Os was formated in fat32

  • Scale an image with unscalable parts

    - by Uko
    Brief description of problem: imagine having some vector picture(s) and text annotations on the sides outside of the picture(s). Now the task is to scale the whole composition while preserving the aspect ratio in order to fit some view-port. The tricky part is that the text is not scalable only the picture(s). The distance between text and the image is still relative to the whole image, but the text size is always a constant. Example: let's assume that our total composition is two times larger than a view-port. Then we can just scale it by 1/2. But because the text parts are a fixed font size, they will become larger than we expect and won't fit in the view-port. One option I can think of is an iterative process where we repeatedly scale our composition until the delta between it and the view-port satisfies some precision. But this algorithm is quite costly as it involves working with the graphics and the image may be composed of a lot of components which will lead to a lot of matrix computations. What's more, this solution seems to be hard to debug, extend, etc. Are there any other approaches to solving this scaling problem?

  • What Am I doing for my 5 months 1 week old baby for his first cold?

    - by Rekha
    With my limited friends circle with babies, I heard that babies in their fifth month usually gets affected by cold all of a sudden. This is unavoidable and I feel it is good for the babies as they start developing their immune system right on. We usually take our son for a small walk so that he is able to explore the world out there. We have been taking him for a stroll almost everyday since we was 3 months old. But only now he is getting his first cold. So things happen only now I think. Till that day I had somehow brought some routine for him for his feed and naps during day time. Night time is still sleepless ones anyway. So when he first got his cold, that night it went on as usual getting up every few hours. From the next day on, he stopped feeding at the usual time. In the night he goes for 8-10 hours between feeds but still wakes up every two hours and cries for about 10 minutes and when we lift him for sometime, he goes back to sleep. Now to the point what all to expect: * Babies starts feeding frequently * Babies spit up increases * They dislike the food they liked before (we have just started solid foods as per our pediatricians advice) * Since they cannot breathe properly, they cannot sleep for a long time *Pees and poops less frequently. What all we did for our baby to make him comfortable during this time: * Feed the baby less quantity and more frequently whenever they expect to feed (Do not follow the schedule) * When the quantity is less, spit ups is also less * If the baby does not like the food (vegetable or fruit), avoid them till they get back to normal * Try to elevate their head while sleeping ( we used the cradle – sitting position, bouncer, car seat and finally all four sides we placed firm pillows so that he does not roll and kept a pillow for his head till his hip – this one is recommended usually but we have an eye on him always) * No need for any medicines – it will take a week for them to get back to normal whether or not we gives medicines * We applied home made Cold Reliever (heat 2 teaspoons of coconut oil with a small camphor piece till the camphor disappears – then cool the mixture) on his chest, back, neck and feet and covered the feet with socks in the nights * Bathe him everyday – hot (that your baby can withstand) *  Whenever possible give him a steam bath (open the hot showers for sometime in the bathroom and close the doors. When the steam is bearable, close the shower and take the baby inside the bathroom for sometime) * Also use a bulb syringe provided in the hospital to clear the nose (use some saline water drops for ease) * Cuddle him when he cries But please do take him to his doctor if he has fever and other symptoms other than cold or the cold persists for more than 5 – 7 days.

  • Developer Training – Importance and Significance – Part 1

    - by pinaldave
    Developer Training - Importance and Significance - Part 1 Developer Training – Employee Morals and Ethics – Part 2 Developer Training – Difficult Questions and Alternative Perspective - Part 3 Developer Training – Various Options for Developer Training – Part 4 Developer Training – A Conclusive Summary- Part 5 Can anyone remember their final day of schooling?  This is probably a silly question because – of course you can!  Many people mark this as the most exciting, happiest day of their life.  It marks the end of testing, the end of following rules set by teachers, and the beginning of finally being able to earn money and work in your chosen field. Beginning in Real World However, many former-students will be disappointed to find out that once they become employees, learning is not over.  Many companies are discovering the importance and benefits to training their employees.  You can breathe a sigh of relief, though, because much for this kind of training there are not usually tests! We often think that we go to school for our younger years so that we do all our learning all at once, and then for the rest of our lives we use that knowledge.  But in so many cases, but especially for developers, the opposite is true.  It takes many years of schools to learn the basics of a field, and then our careers are spent learning to become experts. For this, and so many other reasons, training is very important.  Example one: developer training leads to better employees.  A company is only as good as the people it employs, and one way to ensure that you have employed the right candidate is through training.  Training can take a regular “stone” and polish it into a “diamond.”  Employees who have been well-trained will be better at their jobs and produce a better product. Most Expensive Resource Did you know that one of the most expensive operating costs for any company is not buying goods, or advertising, but its employees – especially having to hire new employees.  Bringing in new people, getting them up to speed, and providing them with perks to attract them to a company is a huge cost for companies.  So employee retention – keep the employees you already have, and keeping them happy – is incredibly important from a business aspect.  And research shows that a well-trained employee is a happy employee.  They feel more confident in their job, happier with their position, and more cared-about – and therefore less likely to leave in search of a better job.  Employee training leads to better retention. Good Moral On the subject of keeping employees happy in order to keep them at a company, the complement to that research shows that happier employees are more efficient and overall better at their jobs.  You don’t have to be a scientist to figure out why this is true.  An employee who feel that his company cares about him and his educational future will work harder for the company.  He or she will put in that extra hour during the busy season that makes all the difference in the end.  Good morale is good for the company. If good morale is better for the company, you know that it goes hand-in-hand with something even better – better efficiency.  An employee who is well trained obviously knows more about their job and all the technical aspects.  That means when a problem crops up – and they inevitably do – this employee will be well-equipped to deal with that problem with fewer problems, and no need to go searching for help from higher up.  When employees are well trained, companies run more smoothly. A Better Product Of course, all of these “pros” for employee training are leading up to the one thing that companies truly care about – a better product.  We have shown that employees who have been trained to be competitive in the market are happier at the company, they are more efficient, and their morale is better.  The overall result is that the company’s product – whether it is a database, piece of equipment, or even a physical good – is better.  And a better product will always be more competitive on the market.

  • Windows Phone–A beautiful phone which I admire but I don’t recommend to friends and family

    - by Gopinath
    Microsoft’s Windows Phones are the most beautiful phones I’ve seen. Look at the photo which Microsoft shared on their Facebook page today. It’s gorgeous. Windows Phones come in vibrant colors and the user interface is very lively. When you keep an iPhone, Android Phone & a Windows Phone on a table, Windows Phone definitely stands out. Android and iOS interfaces are routine – a bunch of apps icons arranged in rows and multiple screens. Windows Phone is very different, the live tiles concept mesmerizes us. I love Windows Phone, but neither I buy one nor I recommend to family/friends! Why? Because it does not have all the Apps I need. Microsoft advertises that Windows Phone has 100K apps on its Windows Market Place. It’s true, there are 100K+ apps available for Windows Phone but not many of them are really useful and most of the popular Apps I use on Android are not available. When I say this to my friends at Microsoft, they don’t agree and one of them asked me list the apps that are not available. For him today I spent an hour quickly scanning through the apps installed on my Google Nexus and searched for same apps on Windows Market Place. As expected many of them are not available. Here is the list of my favorite Android apps that are not available for Windows Phone Mint – I use this app more than any of the Banking Apps I’ve installed on my mobile. It’s one app to keep a tab on all the expenses and income, the best money management and tracking app. Google Chrome – Web without Google Chrome is too boring, either on Desktop or on mobile. IE is too heavy and Firefox is loosing its grip. Chrome is the new darling of web. Pulse, Flipboard – Flipboard and Pulse are one of the best apps for reading news and following content of favorite blogs. Dropbox – Sync content across devices and provides access to your content on any device.It really does not matter what is your gadget – mobile, tablet or computer; Dropbox lets you access your content. GMail, Google Maps – Should I say how important are these two apps in our day to day life!! Vonage Extension – For around 30 bucks a month, Vonage provide landline service in USA + unlimited calls to India and many other countries + Vonage Extension App that lets Android/iOS mobile to make unlimited international calls for free. Without Vonage Extension app, I’m almost cutoff from my family and friends back home in India. Instagram – The most popular camera app used from a common man to celebrities. Raaga, Dhingana  – Music is part and parcel of life and these two apps are the most like popular apps to listen to Indian music. Quora – Quora is the place where most of the sensible discussions happen on web. Google Analytics, Google Adsense – I’m a blogger and these two apps mean a lot to me The list goes on and on! There are many useful apps that are not available on Windows Phone – TuneIn, MyTWC, Chrome To Phone, Google Voice, etc. Without all these apps, Windows Phone is just another old Nokia phone. Even though Windows Phone is the most beautiful phone, it needs Apps to attract customers. Without apps a smartphone is more or less a dumb feature phone which we loved to use before release of iPhone. Wish in an year or two the beautiful Windows Phone may have all the missing Apps. When it happens I’ll buy a phone for myself and recommend it to my family & friends. But till then I prefer to stay away.

  • JustMock and Moles – A short overview for TDD alpha geeks

    - by RoyOsherove
    People have been lurking near my house, asking me to write something about Moles and JustMock, so I’ll try to be as objective as possible, taking in the fact that I work at Typemock. If I were NOT working at Typemock I’d write: JustMock JustMock tries to be Typemock at so many levels it’s not even funny. Technically they work the same and the API almost looks like it’s a search and replace work based on the Isolator API (awesome compliment!), but JustMock still has too many growing pains and bugs to be usable. Also, JustMock is missing alot of the legacy abilities such as Non public faking, faking all types and various other things that are really needed in real legacy code. Biggest thing (in terms of isolation integration) is that it does not integrate with other profilers such as coverage, NCover etc.) When JustMock comes out of beta, I feel that it should cost about half as Isolator costs, as it currently provides about half the abilities. Moles Moles is an addon of Pex and was originally only intended to work within the Pex environment. It started as a research project and now it’s a power-tool for VS (so it’s a separate install) Now it’s it’s own little stubbing framework. It’s not really an Isolation framework in the classic sense, because it does not provide any kind of API built in to verify object interactions. You have to use manual flags all on your own to do that. It generates two types of classes per assembly: Manual Stubs(just like you’d hand code them) and Mole classes. Each Mole class is a special API to change and break the behavior that the corresponding type. so MDateTime is how you change behavior for DateTime. In that sense the API is al over the place, and it can become highly unreadable and unmentionable over time in your test. Also, the Moles API isn’t really designed to deal with real Legacy code. It only deals with public types and methods. anything internal or private is ignored and you can’t change its behavior. You also can’t control static constructors. That takes about 95% of legacy scenarios out of the picture if that’s what you’re trying to use it for. Personally, I found it hard to get used to the idea of two parallel APIs for different abilities, and when to choose which. and I know this stuff. I would expect more usability from the API to make it more widely used. I don’t think that Moles in planning to go that route. Publishing it as an Isolation framework is really an afterthought of a tool that was design with a specific task in mind, and generic Isolation isn’t it. it’s only hope is DEQ – a simple code example that shows a simple Isolation API built on the Moles generic engine. Moles can and should be used for very simple cases of detouring functionality such a simple static methods or interfaces and virtual functions (like rhinomock and MOQ do).   Oh, Wait. Ah, good thing I work at Typemock. I won’t write all that. I’ll just write: JustMock and Moles are great tools that enlarge the market space for isolation related technologies, and they prove that the idea of productivity and unit testing can go hand in hand and get people hooked. I look forward to compete with them at this growing market.
