• Is there a rational reason to wait for the release date to download, install or update to the next version of Ubuntu?

  - by badp

  Today, October 6th 2010, Ubuntu 10.10 is in Feature Definition Freeze, Debian Import Freeze, Feature Freeze, User Interface Freeze, Beta Freeze, Documentation String Freeze, Final Freeze, Kernel Freeze and past the Translation Deadlines in both the non-language pack and language pack editions as the release schedule details. Basically, except for last minute bugfixes, the version of Ubuntu 10.10 you can download today is identical to the version of Ubuntu 10.10 you can download on the 10th when it gets released. If you downloaded and installed Ubuntu 10.10 today, you would: help find glaring issues for last minute fixing help defray the network load on October 10th see Ubuntu 10.10 in action without waiting Those sound like pretty strong arguments... to me, and indeed I've been using Ubuntu 10.10 for a month now roughly. However, most people prefer to make the jump with everybody else on release day. What are the rational reasons for that?

• Do we need use case levels or not?

  - by Gabriel Šcerbák

  I guess no one would argue for decomposing use cases, that is just wrong. However sometimes it is necessary to specify use cases, which are on lower, more technical level, like for example authetication and authorization, which give the actor value, but are further from his business needs. Cockburn argues for levels when needed and explains how to move use cases from/to different levels and how to determine the right level. On the other hand, e.g. Bittner argues against use case levels, although he uses subflows and at the end of his book mentions, that at least two levels areneeded most of the time. My questionis, do you find use case levels necessary, helpful or unwanted? What are the reasons? Am I misssing some important arguments?

• Should programmers prefer making wide libraries or thin libraries?

  - by Telastyn

  For classes and functions, it is clear cut: each should do only one thing. For libraries though, this is less clear. If you have a library with collections, it might have multiple collections. It might have useful functions like sorting, which aren't strictly collection based but users would expect. Each of these results in a 'wider' library. On the other side is having a library for the specific collection type and/or with little built-in functionality. If you want a queue, it gives you a queue. If you want to sort that list, then the library lets you do that yourself. What is the best practice here (if any)? I can see arguments for each side.

• Should I demand unit-testing from programmers?

  - by Morten

  I work at a place, where we buy a lot of IT-projects. We are currently producing a standard for systems-requirements for the requisition of future projects. In that process, We are discussing whether or not we can demand automated unit testing from our suppliers. I firmly believe, that proper automated unit-testing is the only way to document the quality and stability of the code. Everyone else seems to think that unit-testing is an optional method that concerns the supplier alone. Thus, we will make no demands of automated unit-testing, continous testing, coverage-reports, inspections of unit-tests or any of the kind. I find this policy extremely frustrating. Am I totally out of line here? Please provide me with arguments for any of the oppinions.

• Mobile app technology choice - popularity trend data?

  - by Ryan Weir

  I'm familiar with the arguments for HTML5 apps over native, but was looking for some numbers or data to indicate a trend of how popular they are relative to each other for mobile app development. E.g. Surveys among programmers, data collected from the various app stores, number of downloads of development tools for those platforms. Your source could consider new apps, existing apps, categorized by downloads, app downloads weighted by popularity - basically any source you've got I would like to see. In my own personal monkey-sphere of developers, HTML5 seems to be starting to dominate as of about 6 months ago over iOS and Android by a wide margin as the technology stack preference - so I was wondering if this reflects a trend that's been measured globally and if there was objective data to support it.

• Survival rate of open source projects

  - by Shogoot

  I'm trying to write a paper on why or why not an open source project will have good odds for survival or not. I've found very few articles on the Internet on the topic or I'm just searching with the wrong terms. I've tried: "open source" survival "open source" success failure "open source" determinants for success So far i've only found this, which says some on the topic. So I turn to you my dear stackers! Help me find some arguments and articles that will throw some clarity on the subject.

• Firefox : Mozilla travaille sur une version sans onglet pour iPad et sur deux autres projets « de rupture » pour son navigateur

  Firefox : Mozilla travaille sur une version sans onglet pour iPad Et sur deux autres projets « de rupture » pour son navigateur Aussi curieux que cela puisse paraitre, Firefox ? un des navigateurs les plus populaires au monde ? n'est pas présent sur la tablette la plus populaire de la planète. Jusqu'ici, Mozilla expliquait cette absence avec plusieurs arguments... qui semblent aujourd'hui être caduques puisque la fondation annonce qu'elle travaille sur un Firefox pour iPad.

• Are there well-known PowerShell coding conventions?

  - by Tahir Hassan

  Are there any well-defined conventions when programming in PowerShell? For example, in scripts which are to be maintained long-term, do we need to: Use the real cmdlet name or alias? Specify the cmdlet parameter name in full or only partially (dir -Recurse versus dir -r) When specifying string arguments for cmdlets do you enclose them in quotes (New-Object 'System.Int32' versus New-Object System.Int32 When writing functions and filters do you specify the types of parameters? Do you write cmdlets in the (official) correct case? For keywords like BEGIN...PROCESS...END do you write them in uppercase only? It seems that MSDN lack coding conventions document for PowerShell, while such document exist for example for C#.

• Does Microsoft really offer "support"?

  - by SpashHit

  One of the arguments against using Open Source is that there is no "support". However, do big vendors (e.g. Microsoft) really offer "support" of any kind? I'm sure there is some sort of 4-figure-per-hour "paid support" option out there, but is that really an "option" for any problem short of one that is going to bankrupt your business? To put it more concretely... I buy a Microsoft product... it has a bug... now what? And how is that better than what I get from Open Source?

• gvim configuration does not work like it should

  Hi. I have a little problem with my vim config.

• Do you use your personal laptop for work?

  - by davekaro

  We're trying to get our company to let us use our own personal laptop for client work. We've agreed that any code/data will be encrypted using something like TrueCrypt, in case the laptop is stolen or lost. However, the company is still skeptical and not sure they want to allow us to use our personal machines for development. They would rather buy us laptops... but we want to use MacBook Pros and they don't want to pay for them. Even if they did buy us laptops, we would stil have the issue of needing to encrypt the code/data in case of theft/loss. Do you use your own laptop for work? What are the arguments for/against this?

• Is ORM an Anti-Pattern?

  - by derphil

  I had a very stimulating and interessting discussion with a colleague about ORM and it's Pros and Cons. In my opinion, an ORM is useful only in the rarest cases. At least in my experience. But I don't want to list my own arguments at this time. So I ask you, what do you think about ORM? What are the Pros and the Cons? P.S. I've posted this "question" yesterday on Stackoverflow, but some of the user think, that this should better posted here.

• Tack anchor link with Google Analytics

I have this code in the header: <script> (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){ (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o), m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m) })(window,document,'script','//www.google-analytics.com/analytics.js','ga'); ga('_setAllowAnchor', true); ga('create', 'UA-*******-1', '****.com'); ga('send', 'pageview'); </script> And my links looks like this: <a href='#/contact'><span>Contact</span></a> I also tried to use this links: <a href='#/contact' onClick="_gaq.push(['_trackPageview', location.pathname+location.search+location.hash]);"><span>Contact</span></a> Is there any tips on what I can do?

• Is having a class have a handleAction(type) method bad practice?

  - by zhenka

  My web application became a little too complicated to do everything in a controller so I had to build large wrapper classes for ORM models. The possible actions a user can trigger are all similar and after a certain point I realized that the best way to go would be to just have constructor method receive action type as a parameter to take care of the small differences internally, as opposed to either passing many arguments or doing a lot of things in the controller. Is this a good practice? I can't really give details for privacy issues.

• Fixed Bid vs. T&amp;M &ndash; Take 2

  - by AjarnMark

  One of my most popular blog entries of all time is my Contracting Tips: Fixed Bid vs. T&M post from January, 2004.  This post consistently shows up in my referrers list, usually coming from a search engine.  Recently, Brent Ozar (@BrentO) wrote a great argument for why he always bills by the hour (a.k.a. Time & Materials or T&M) which itself was a response to Mark Richman’s (@mrichman) post on why he never bills by the hour (fixed bid).  Each article has good arguments, and I encourage you to read them both and choose the best approach for you. As for me, my experience parallels Brent’s and I historically have leaned toward the Time & Materials model.

• Make the JavaScript Test Pass

• Method chaining vs encapsulation

  - by Oak

  There is the classic OOP problem of method chaining vs "single-access-point" methods: main.getA().getB().getC().transmogrify(x, y) vs main.getA().transmogrifyMyC(x, y) The first seems to have the advantage that each class is only responsible for a smaller set of operations, and makes everything a lot more modular - adding a method to C doesn't require any effort in A, B or C to expose it. The downside, of course, is weaker encapsulation, which the second code solves. Now A has control of every method that passes through it, and can delegate it to its fields if it wants to. I realize there's no single solution and it of course depends on context, but I would really like to hear some input about other important differences between the two styles, and under what circumstances should I prefer either of them - because right now, when I try to design some code, I feel like I'm just not using the arguments to decide one way or the other.

• Level and Player objects - which should contain which?

  - by Thane Brimhall

  I've been working on a several simple games, and I've always come to a decision point where I have to choose whether to have the Level object as an attribute of the Player class or the Player as an attribute of the Level class. I can see arguments for both: The Level should contain the player because it also contains every other entity. In fact it just makes sense this way: "John is in the room." It makes it a bit more difficult to move the player to a new level, however, because then each level has to pass its player object to an upcoming level. On the other hand, it makes programming sense to me to leave the player as the top-level object that is persistent between levels, and the environment changes because the player decides to change his level and location. It becomes very easy to change levels, because all I have to do is replace the level variable on the player. What's the most common practice here? Or better yet, is there a "right" way to architecture this relationship?

• Should you document everything or just most?

  - by TheLQ

  It seems a bit of a controversial subject to document everything, including the "JavaBean" syntax of getters and setters for fields: People say its needlessly long and repetitive breaking DRY (don't repeat yourself), that the naming convention should explain everything, and it clutters code/documentation. Sometimes those arguments work. But other times, you end up with this: Above is common to open source projects that do boldly follow those principles. Your left with entirely useless documentation. That doesn't explain anything about whats going on underneath, the possible effects, or even what the expected value is (could it be null or never null? I don't know, the Javadoc doesn't tell me). So when should I document? Do I document everything even if it occasionally clutters code? Or do I document nothing since in my eyes its "obvious"?

• Application development : method to manage backgound process

  - by Simon Dubois

  I am developing an application with different behavior depending on the arguments : - "-config" starts a Gtk window to change options, start and close the daemon. - "-daemon" starts a background process that does something every X minutes. I already know how to use fork/system/exec etc... But I would like to know the main logic of such application to : - restart or refresh the daemon when configuration change. - keep only one instance of the daemon. I have red that killing the daemon to restart it is not a clean way to do. How other applications do ? (ubuntuone, weather forecast, rss feed working with notification area) Thanks for your help. PS : I don't want to create a system-wide daemon, just a user application with a background process.
