• What are the basic skills a beginner JavaScript programmer should have?

  - by Sanford

  In NYC, we are working on creating a collaborative community programming environment and trying to segment out software engineers into differing buckets. At present, we are trying to define: Beginners Intermediates Advanced Experts (and/or Masters) Similar to an apprenticeship, you would need to demonstrate specific skills to achieve different levels. Right now, we have identified beginner programming skills as: Object - method, attributes, inheritance Variable - math, string, array, boolean - all are objects Basic arithmetic functions - precedence of functions String manipulation Looping - flow control Conditionals - boolean algebra This is a first attempt, and it is a challenge since we know the natural tension between programming and software engineering. How would you create such a skills-based ranking for JavaScript in this manner? For example, what would be the beginner JavaScript skills that you would need to have to advance to the intermediate training? And so on.

• Project of Projects with team Foundation Server 2010

  - by Martin Hinshelwood

  It is pretty much accepted that you should use Areas instead of having many small Team Projects when you are using Team Foundation Server 2010. I have implemented this scenario many times and this is the current iteration of layout and considerations. If like me you work with many customers you will find that you get into a grove for how to set these things up to make them as easily understandable for everyone, while giving the best functionality. The trick is in making it as intuitive as possible for both you and the developers that need to work with it. There are five main places where you need to have the Product or Project name in prominence of any other value. Area Iteration Source Code Work Item Queries Build Once you decide how you are doing this in each of these places you need to keep to it religiously. Evan if you have one source code file to keep, make sure it is in the right place. This makes your developers and others working with the format familiar with where everything should go, as well as building up mussel memory. This prevents the neat system degenerating into a nasty mess. Areas Areas are traditionally used to separate out parts of your product / project so that you can see how much effort has gone into each. Figure: The top level areas are for reporting and work item separation There are massive advantages of using this method. You can: move work from one project to another rename a project / product It is far more likely that a project or product gets renamed than a department. Tip: If you have many projects, over 100, you should consider categorising them here, but make sure that the actual project name always sits at the same level so you know which is which. Figure: Always keep things that are the same at the same level Note: You may use these categories only at the Area/Iteration level to make it easier to select on drop down lists. You may not want to use them everywhere. On the other hand, for consistency it would be better to. Iterations Iterations are usually used to some sort of time based consideration. Here I am splitting into Iterations with periodic releases. Figure: Each product needs to be able to have its own cadence The ability to have each project run at its own pace and to enable them to have their own release schedule is often of paramount importance and you don’t want to fix your 100+ projects to all be released on the same date. Source Code Having a good structure for your source even if you are not branching or having multiple products under the same structure is always a good idea. Figure: Separate out your products source You need to think about both your branches as well as the structure of your source. All your code should be under “Source” and everything you need to build your solution including Build Scripts and 3rd party tools should be under your “Main” (branch) folder. This should them be branched by “Quality”, “Release” or both to get the most out of your branching structure. The important thing is to make sure you branch (or be able to branch) everything you need to build, test and deploy your application to an environment. That environment may be development, test or even production, but I can’t stress the importance of having everything your need. Note: You usually will not be able to install custom software on your build server. Store any *.dll’s or *.exe’s that you need under the “Tools\Tool1” folder. Note: Consult the Branching Guidance for Team Foundation Server 2010 for more on branching Figure: Adding category may be a necessary evil Even if you have to have a couple of categories called “Default”, it is better than not knowing the difference between a folder, Product and Branch. Work Item Queries Queries are used to load lists of Work Items out of TFS so you can see what work you have. This means that you want to also separate queries out by Product / project to make it easier to Figure: Again you have the same first level structure Having Folders also in Work Item Tracking we do the same thing. We put all the queries under a folder named for the Product / Project and change each query to have “AreaPath=[TeamProject]\[ProductX]” in the query instead of the standard “Project=@Project”. Tip: Don’t have a folder with new queries for each iteration. Instead have a single “Current” folder that has queries that point to the current iteration. Just change the queries as you move from one iteration to another. Tip: You can ctrl+drag the “Product1” folder to create your “Product2” folder. Builds You may have many builds both for individual products but also for different quality's. This can be further complicated by having some builds that action “Gated Check-In” and others that are specifically for “Release”, “Test” or another purpose. Figure: There are no folders, yet, for the builds so you need a good naming convention Its a pity that there are no folders under builds, some way to categorise would be nice. In lue of that at the moment you can use a functional naming convention that at least allows you to find what you want. Conclusion It is really easy to both achieve and to stick to this format if you take the time to do it. Unless you have 1000+ builds or 100+ Products you are unlikely run into any issues. Even then there are things you can do to mitigate the issues and I have describes some of them above. Let me know if you can think of any other things to make this easier.

• OpenGL 2D Rasterization Sub-Pixel Translations

  - by Armin Ronacher

  I have a tile based 2D engine where the projection matrix is an orthographic view of the world without any scaling applied. Thus: one pixel texture is drawn on the screen in the same size. That all works well and looks nice but if the camera makes a sub-pixel movement small lines appear between the tiles. I can tell you in advance what does not fix the problem: GL_NEAREST texture interpolation GL_CLAMP_TO_EDGE What does “fix” the problem is anchoring the camera to the nearest pixel instead of doing a sub-pixel translation. I can live with that, but the camera movement becomes jerky. Any ideas how to fix that problem without resorting to the rounding trick I do currently?

• How do I keep track of modifications to a new server?

  - by eveo

  I purchased a server for the sole purpose of familiarizing myself with the CLI so I don't get royally screwed when I enter a real development environment. However, I have some questions. I've managed to SSH into my server, all is fine and dandy, installed LAMP too which went flawlessly. Now I'm wondering, the more changes I do, the more cluttered my server will become. Can I revert changes? I don't want to keep customizing things and installing things and just having a cluttered server overall. Where can I track changes to my system?

• Looking for a very subtle unit testing example

  - by Stéphane Bruckert

  In the context of Continuous Integration, I need to teach unit testing to a 20-people audience of programmers. Everything will be all right, but I am still trying to find the perfect unit testing example. More than writing tests like a robot, I want to show that unit testing can help prevent very subtle errors. I am thinking of the following scenario to happen when doing a live TDD demo: the test cases would already be written, we would have to write methods together, most of us would naturally have forgotten to handle a specific case for a method, everyone would then be surprised, when seeing that all tests don't pass, the failing test would make us think more and realize that we forgot an important case. My question will probably finish as "too broad" or "not clear what you are asking", but we never know, one of you might have a great idea. Your answer can use Java and JUnit, though any other language will be fine since only the idea will matter.

• How to point DNS records to Amazon AWS Elastic Beanstalk

  - by Lance

  I just created a new environment with AWS and uploaded a .zip file into elastic beanstalk. I used to have a friend's server host my site instead of GoDaddy so I changed my custom DNS name servers from pointing to my friend's server to GoDaddy's. AWS told me that I need I need to add a CNAME record on GoDaddy and I did. The alias is lance and the host is lance-env.elasticbeanstalk.com. I know that this change can take 24-48 hours to take effect but it's been a day already and when I go to my site, a default page from GoDaddy appears. I'm very new to AWS and would just like to find a way for AWS to host my site other than using Route53.

• How to make custom libraries accessible?

  - by Milen Bilyanov

  I am trying to compile and install every custom module under it's own designated folder. (ex: /myApps/myLinux/compiled_app) I had luck with python so far, where my python is compiled from source and lives in: /myApps/myLinux/python2.5 and "python2.5" - /myApps/myLinux/python2.5.6-gcc463 so I can access this python through a wrapper script that sets the right environment. The question is recently I had to compile and add something called gperf3.0.4. So now it lives: /myApps/myLinux/gperf3.0 and "gperf3.0" - /myApps/myLinux/gperf3.0.4-gcc463 The question is: How will I point to this lib if some other app needs to access it? Is it done through the LD_LIBRARY_PATH variable? Thanks.

• How do I disable window move with alt + left mouse button in GNOME Shell?

  - by artfulrobot

  There are lots of posts on this about Unity, this is about gnome-shell As with other posters, I use apps (Inkscape in particular) that uses Alt-Click and Alt-drag. Gnome-shell is grabbing this off me and thus disabling features in the application. I have tried using ccsm's Move plugin - you can turn this off and you still get Alt-drag window moving. using gconf editor to change /apps/metacity/general/mouse_button_modifier - this has no effect AFAICS. It's really hindering me. Otherwise I find gnome-shell a really productive environment.

• How to write efficient code in spite of heavy deadlines

  - by gladysbixly

  Hi all, I am working in an environment wherein we have many projects with strict deadlines on deliverables. We even talk directly to the clients so getting the jobs done and fast is a must. My issue is that i'd always write code for the first solution that comes to my mind, which of course I thought as best at that moment. It always ends up ugly though and i'd later realize that there are better ways to do it but can't afford to change due to time restrictions. Are there any tips by which I could make my code efficient yet deliver on time?

• Registration free hosting for ASP.NET web service

  - by Andrew

  I've built a simple ASP.NET web service, tested it locally and would like to test it when externally hosted. Are there free hosting services available where I can just upload the assembly and service description file and test it straight away. Without registering the account, etc. My service does not do anything malicious and I am ok to run it in a restricted (security sandbox, bandwith, calls per second, etc) environment? I have heard about appharbor.com but it looks like an overkill to test a simple web service.

• Adding included columns to indexes using SMO

  - by Greg Low

  A question came up on the SQL Down Under mailing list today about how to add an included column to an index using SMO. A quick search of the documentatio didn't seem to reveal any clues but a little investigation turned up what's needed: the IndexedColumn class has an IsIncluded property. Index i = new Index (); IndexedColumn ic = new IndexedColumn (i, "somecolumn" ); ic.IsIncluded = true ; Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!...(read more)

• Is the "App" side of Windows 8 practical for programmers?

  - by jt0dd

  I like the tablet-friendliness of Windows 8 Apps, and some of the programming apps seem pretty neat, but there are many aspects that make me think I would have difficulty using this format for an efficient programming environment: Unlike the desktop + multiple windows setup, I can't simply drag my files around from source, to FTP or SFTP file managers, between folders, web applications, and into other apps, etc. I can't switch between apps as fast. This could have different implications with different monitor setups, but it seems like a shaky setup for an agile workflow. The split screen functionality is cool, but it doesn't seem to allow for as much maneuverability as the classic desktop setup. This could just require me getting used to the top-left corner shortcut, but it does bother me that I have to move my mouse all the way up there to see my different windows. These aspects could become relevant in the event that Windows were to move further towards their "app" structure and less towards the Windows 7 style. I'm wondering if anyone has been able to utilize the "App" side of Windows 8 for an efficient programming workflow.

• GTK applications do not start

  - by Greg

  Hello, I have a fresh install of Ubuntu 10.04 Server on nodes of a computational cluster, and I access the nodes via ssh. I configured a X server, which I start with the command startx -- -ac. The server is running fine on port :0. Then, I set the environment variable DISPLAY to :0. Now, when I run a GTK application on the node, it fails with the following error: Error: Unable to initialize gtk, is DISPLAY set properly? Now, my question is, is there any runtime library that I need for running GTK applications on top of a X server? I'm probably missing something obvious here, but I can't tell what :P

• How can I reply to email by sending a delivery failure message?

  - by wau

  Occasionally, I receive unwanted emails, particularly low-volume spam, or email messages falsely addressed to me (possibly due to typos). I don't want to spend the energy to write a personal message, but I do want to let the sender know that the message never arrived at its destination, and that resending it will be useless. In my opinion, a delivery error message to the sender will fill that need. So, the question is if there is an easy way to send error messages back to the sender. Is there any email client out there which supports sending delivery failure messages as a reply to incoming email -- ideally in one click? (Or, which can be configured to do so?) Alternatively, what is the best way to set up an environment that allows me to send delivery failure messages without too much effort per message sent?

• xmonad keyboard doesn't work

  - by Mikkel Paulson

  I'm experimenting with xmonad, which I installed from the Ubuntu Software Centre on Ubuntu 12.10. It looks cool, but when I invoke it (using xmonad --replace from the command line) my title bars disappear and my keyboard stops working. At all. The terminal stops working, the keystrokes I've seen in online "getting started" guides are ignored, and the only way for me to actually power the system off is to hit the reset button or ssh in from my phone. Ironically, my mouse still works. One guide I saw suggested replacing the default window environment with xmonad, but I'm afraid of rendering my system completely inoperable if I do that. Any suggestions?

• My wireless/WiFi connection does not work. What can I do?

  - by Wild Man

  Your situation You have successfully installed Ubuntu. You have just downloaded and booted Ubuntu live media. The latest LTS (see also HWE) or latest non-LTS release are preferred. See the list of Ubuntu releases that are currently supported.) You upgraded your Ubuntu installation to the latest release that the software updater offered you. WiFi worked before, but not now on the new release. You migrated your existing Ubuntu installation to new hardware. Your problem The wireless of your laptop or dekstop is not working. You tried switching the wireless switch off and on and you tried rebooting several times, but you don't see any WiFi access points. You can see your wireless access point, but you cannot establish a connection. You want to analyze the problem, but you don't know where to start or what information you can provide. Related questions I have a hardware detection problem, what logs do I need to look into?

• What do you need to know to get a job as a web developer

  - by Alex Foster

  What do you need to know to at the very least get your foot in the door? We're assuming for someone who doesn't have a college degree (yet) but will eventually get one. My guess is html, css, javascript, and php, and photoshop and dreamweaver, and sql. And being familiar with using a web host to have sites live, like knowing how to use cpanel. It's probably a very inaccurate and narrow guess but that's what i think right now. I don't know exactly.
