  • What are the roles of a Software Delivery Manager

    - by Rich
    I have been told about a position that may be open to me - the role of a Software Delivery Manager. From what I understand this role does not already exist within my organisation. To be perfectly honest I'm not quite sure what a Software Delivery Manager's roles are. I have a few ideas and would appreciate some input around whether they are correct or not, or if there is anything missing: ensure the quality of the software being delivered document the relationships between the components being delivered ensure that the delivery of these components does not break other components ensure that the components being developed make the best use of the environments they are being deployed in being on-hand during software deliveries (though not actually performing the delivery of software, rather giving the Go) I have also been told that the role would include some software development work (which is important to me being a developer at heart!) - is there software development specifically associated with the role of Software Delivery Manager or is this more likely to just be a case of helping the team out when time is short?

  • Nested languages code smell

    - by l0b0
    Many projects combine languages, for example on the web with the ubiquitous SQL + server-side language + markup du jour + JavaScript + CSS mix (often in a single function). Bash and other shell code is mixed with Perl and Python on the server side, evaled and sometimes even passed through sed before execution. Many languages support runtime execution of arbitrary code strings, and in some it seems to be fairly common practice. In addition to advice about security and separation of concerns, what other issues are there with this type of programming, what can be done to minimize it, and is it ever defensible (except in the "PHB on the shoulder" situation)?

  • LINQ Style preference

    - by Erin
    I have come to use LINQ in my every day programming a lot. In fact, I rarely, if ever, use an explicit loop. I have, however, found that I don't use the SQL like syntax anymore. I just use the extension functions. So rather then saying: from x in y select datatransform where filter I use: x.Where(c => filter).Select(c => datatransform) Which style of LINQ do you prefer and what are others on your team are comfortable with?

  • Is true multithreading really necessary?

    - by Jonathan Graef
    So yeah, I'm creating a programming language. And the language allows multiple threads. But, all threads are synchronized with a global interpreter lock, which means only one thread is allowed to execute at a time. The only way to get the threads to switch off is to explicitly tell the current thread to wait, which allows another thread to execute. Parallel processing is of course possible by spawning multiple processes, but the variables and objects in one process cannot be accessed from another. However the language does have a fairly efficient IPC interface for communicating between processes. My question is: Would there ever be a reason to have multiple, unsynchronized threads within a single process (thus circumventing the GIL)? Why not just put thread.wait() statements in key positions in the program logic (presuming thread.wait() isn't a CPU hog, of course)? I understand that certain other languages that use a GIL have processor scheduling issues (cough Python), but they have all been resolved.

  • List of eCommerce sites that use end-to-end SSL?

    - by Jon Schneider
    My development team is considering implementing an eCommerce site using end-to-end SSL -- that is, every page on the site is accessed via an https:// URL -- rather than the more traditional "mixed mode" where most pages are accessed via http:// and only "secure" pages such as login and credit card entry are redirected to https://. Pros of doing such a "pure SSL" approach include avoidance of some session-hijacking attacks such as Firesheep; cons include performance considerations. My question is: Is anyone aware of a list of eCommerce websites (especially USA-based sites), or even specific websites, that use this end-to-end SSL approach? I'm especially interested in "regular" eCommerce sites rather than banks or other "financial" sites.

  • Why write clean, refactored code?

    - by Shamal Karunarathne
    Hi programming lovers, This is a question I've been asking myself for a long time. Thought of throwing out it to you. From my experience of working on several Java based projects, I've seen tons of codes which we call 'dirty'. The unconventional class/method/field naming, wrong way of handling of exceptions, unnecessarily heavy loops and recursion etc. But the code gives the intended results. Though I hate to see dirty code, it's time taking to clean them up and eventually comes the question of "is it worth? it's giving the desired results so what's the point of cleaning?" In team projects, should there be someone specifically to refactor and check for clean code? Or are there situations where the 'dirty' codes fail to give intended results or make the customers unhappy? Do feel free to comment and reply. And tell me if I'm missing something here. Thanks.

  • Authentication for users on a Single Page App?

    - by John H
    I have developed a single page app prototype that is using Backbone on the front end and going to consume from a thin RESTful API on the server for it's data. Coming from heavy server side application development (php and python), I have really enjoyed the new different design approach with a thick client side MVC but am confused on how best to restrict the app to authenticated users who log in. I prefer to have the app itself behind a login and would also like to implement other types of logins eventually (openid, fb connect, etc) in addition to the site's native login. I am unclear how this is done and have been searching - but unsuccessful in finding information that made it clear to me. In the big picture, what is the current best practice for registering users and requiring them to login to use your single page app? Once a user is logged in, how are the api requests authenticated? Can I store a session but how do I detect for this session in the API calls? Any answers to this would be much appreciated!

  • Are Java certifications important for an architect role?

    - by Tahir Akram
    My this question is career path related. I want to know how much Java Certifications (SCJP, SCWCD and others) are important for an architect position. If a person posses a good experience in Java development and want to pursue his career on architect level, do you guys think he need to have certification on his CV. If he has never worked on lead developer roles? If you conducting my interview for an architect position. And I have worked as a Java web developer in different teams having 5 years of exp. Never lead any. And I am having certification badges on my CV. How can a developer make his career path towards being an architect in a team?

  • Build Controller status Unavailable issue in TFS2010

    - by jehan
    I ran into this problem few days back, I was not able to run the builds because the Build Controller was showing Status as Unavailable. It was showing the below exception: There was no endpoint listening at http://fullmachinename:9191/Build/v3.0/Services/Controller/2 that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. After trying out few things, I looked at below Build Service Properties.   Then, I did below modifications to the Build Services Properties: 1)      Changed the Local Build Service Endpoint(incoming) from http://machinename.domain.com:9191 to http://machinename:9191 2)      Changed the Connect to Team Project Collection (outgoing) from localhost to machine name. http://localhost:8080/tfs/defaultCollection to http://machinename:8080/tfs/DefaultCollection   After that Started the Build Services and it fixed the issue, the Build Controller was showing Available Status and was able to run the builds.

  • On a queue, which end is the "head"?

    - by Aidan Cully
    I had always thought that the "head" of a queue as the next element to be read, and never really questioned that usage. So a linked-list library I wrote, which is used for maintaining queues, codified that terminology: we have a list1_head macro that retrieves the first element; when using this library in a queue, this will be the first element to be removed. But a new developer on the team was used to having queues implemented the other way around. He described a queue as behaving like a dog: you insert at the head, and remove at the tail. This is a clever enough description that I feel like his usage must be more widespread, and I don't have a similarly evocative description of my preferred usage. So, I guess, there are two related questions: 1, what does the "head" of a queue mean to you? and 2, why do we use the word "head" to describe that concept?

  • Do you develop with localization in mind?

    - by Jimmy C
    When working on a software project or a website, do you develop with localization in mind? By this I mean e.g. Externalizing all strings, including error messages. Not using images that contain text. Designing your UI with text expansion in mind. Using pseudo-translation to test your UI's early in the process. etc. On projects you work on, are these in the 'nice to have' category and let the L10N team worry about the rest, or do you have localization readiness built into your development process? I'm interested to hear how developers view localization in general.

  • HTML5 &lt;VIDEO/&gt; + IE9

    Yesterday at MIX Dean (general manager of the IE team) announced the availability of the first IE9 Platform Preview for developers. Dean also committed to updating the preview approximately every eight weeks. There is a good article on Beta News covering some of the technical details of the release. A key part of the announcements was the support for hardware accelerated HTML5 including supporting the video tag with the H.264 codec. What Im going to write next is based on a number of years of observations...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Should programming languages be strict or loose?

    - by Ralph
    In Python and JavaScript, semi-colons are optional. In PHP, quotes around array-keys are optional ($_GET[key] vs $_GET['key']), although if you omit them it will first look for a constant by that name. It also allows 2 different styles for blocks (colon, or brace delimited). I'm creating a programming language now, and I'm trying to decide how strict I should make it. There are a lot of cases where extra characters aren't really necessary and can be unambiguously interpreted due to priorities, but I'm wondering if I should still enforce them or not to encourage good programming habits. What do you think?

I discussed with the support team of my hosting and they said... Hi, I have verified apache logs, i cannot see any issues on your website/webserver/ Possible issues. There may the routing issue from the googles server to our server. When a google bots hits goes high the IP will be automatically blacklisted by our firewall to avoid server loads & downtimes.

  • Extension Manager in Visual Studio 2010

    One of the powerful aspect of Visual Studio is its ability to be extended and many people do that. You can find numerous extensions at the Visual Studio Gallery. The VSX team links to a 4-part blog series on how to create and share templates. You can also look find extension examples on the vsx code gallery.With Visual Studio 2010, you can search for items and install them directly from within Visual Studio's new Extension Manager. You launch it from the Tools menu:When the dialog comes up, be sure to explore the various actionable areas on the left and also note the search on the right. For example, I typed "MP" and it quickly filtered the list to show me the MPI Project Template:Others have written about this before me, just bing Extension Manager (and note that Beta2 introduced changes, some of which you can witness in the screenshot above).

  • Permissions and MVC

    - by not-rightfold
    I’m in the progress of developing a web application. This web application is mostly a CRUD interface, although some users are only allowed to perform some actions and see only some parts of views. What would be a reasonable way to handle user permissions, given that some parts of views are not available to users? I was thinking of having a function hasPermission(permission) that returns true iff the current user has the given permission, although it would require conditionals around all parts of views that are only visible to some users. For example: {% if has_permission('view_location') %} {{ product.location }} {% endif %} I’m fearing this will become an ugly and unreadable mess, especially since these permissions can get kind of complicated. How is this problem commonly solved in web applications? I’m considering using Haskell with Happstack or Python with Django.

  • What is the relationship between the business logic layer and the data access layer?

    - by Matt Fenwick
    I'm working on an MVC-ish app (I'm not very experienced with MVC, hence the "-ish"). My model and data access layer are hard to test because they're very tightly coupled, so I'm trying to uncouple them. What is the nature of the relationship between them? Should just the model know about the DAL? Should just the DAL know about the model? Or should both the model and the DAL be listeners of the other? In my specific case, it's: a web application the model is client-side (javascript) the data is accessed from the back-end using Ajax persistence/back-end is currently PHP/MySQL, but may have to switch to Python/GoogleDataStore on the GAE

  • What are the pro/cons of Unity3D as a choice to make games ?

    - by jokoon
    We are doing our school project with Unity3d, since they were using Shiva the previous year (which seems horrible to me), and I wanted to know your point of view for this tool. Pros: multi platform, I even heard Google is going to implement it in Chrome everything you need is here scripting languages makes it a good choice for people who are not programming gurus Cons: multiplayer ? proprietary, you are totally dependent of unity and its limit and can't extend it it's less "making a game from scratch" C++ would have been a cool thing I really think this kind of tool is interesting, but is it worth it to use at school for a project that involves more than 3 programming persons ? What do we really learn in term of programming from using this kind of tool (I'm ok with python and js, but I hate C#) ? We could have use Ogre instead, even if we were learning direct x starting january...

  • Is it good practice to analyse who introduced each bug?

    - by Michal Czardybon
    I used to analyse performance of programmers in my team by looking at the issues they have closed. Many of the issues are of course bugs. And here another important performance aspect comes - who introduced the bugs. I am wondering, if creating a custom field in the issue tracking system "Blamed" for reporting the person who generated the problem, is a good practice. One one hand it seems ok to me to promote personal responsibility for quality and this could reduce the additional work we have due to careless programming. On the other hand this is negative, things are sometimes vague and sometimes there is a reason such us "this thing had to be done very quickly due to a client's...". What to you think?
