  • Vocabulary: Should I call this apply or map?

    - by Carlos Vergara
    So, I'm tasked with organizing the code and building a library with all the common code among our products. One thing that seems to happen all the time and I wanted to abstract is posted below in pseudocode, and I don't know how to call it (different products have different domain specific implementations and names for it) list function idk_what_to_name_it ( list list_of_callbacks, value common_parameter ): list list_of_results = new list for_each(callback in list_of_callbacks) list_of_results.push(callback(common_parameter)) end for_each return list_of_results end function Would you call this specific construct a list ListOfCallbacks.Map( value value_to_map) method or would it better be value Value.apply(list list_of_callbacks) I'm really curious about this kind of thing. Is there a standard guide for this stuff?

  • juju: How do I list all the relation variables and debug them interactively?

    - by mfisch
    I'm writing a charm that requires a mysql database, I found from looking at other charms that this (below) is how I get the info about the database: user=`relation-get user` password=`relation-get password` mysqlhost=`relation-get private-address` But I just found that from reading the wordpress charm example, is there a way to show all the relation variables that I can use? Also, while debugging my db-relation-changed script, I wanted to ssh into my host and interactively run those commands, for example relation-get user, but it didn't work. I resorted to having to restart everything and use juju log to print them out. This wasted a lot of time. Is there a way to print out these relations, either from my dev box or from the instance running my charm? (Below is what happens when I tried to interactively run relation-get): ubuntu@mfisch-local-tracks-0:~$ relation-get user usage: relation-get [-h] [-o OUTPUT] [-s SOCKET] [--client-id CLIENT_ID] [--format FORMAT] [--log-file FILE] [--log-level CRITICAL|DEBUG|INFO|ERROR|WARNING] [-r RELATION ID] [settings_name] [unit_name] No JUJU_AGENT_SOCKET/-s option found

  • How to structure my java packages

    - by MightyPork
    I have a Java library, quite a huge one. I'm asking regarding Best Practices of structuring the source. For example, the logging sybsystem: Option 1: All in one package, named to sort nicely Log - static accessor LogMonitor - interface for log minotor LogMonitorBase - abstract class LogMonitorStdout - print log to console LogWriter - interface for file logger LogWriterSimple - log writer with just one log file LogWriterArchiving - log writer that handles old log files Option 2: Subpackages for Monitors and Writers, with better names Log monitors/LogMonitor monitors/BaseMonitor monitors/StdoutMonitor writers/LogWriter writers/SimpleLog writers/ArchivingLog The second maybe looks better, but perhaps it's not so practical from the java point of view (two extra packages). What do you suggest as the best practice here? A lot in one package, grouped by naming prefixes, or a lot of subpackages with better names?

  • How can I make Banshee re-encode FLAC to Ogg Vorbis when copying to my player?

    - by Michael E
    I have most of my music in FLAC on my large storage device, and would like to automatically re-encode it in Ogg Vorbis when copying it to my portable audio player (Sansa Fuze v2). I have set my Fuze to MTP mode and told Banshee to encode to Ogg Vorbis with quality 4 in the Device Properties dialog for the Fuze (I would use MSC mode, but don't have an encoding option in the device properties when I do that). However, when I copy music to the device, either by dragging it from the music library or by syncing a playlist, the full FLAC files are copied rather than transcoded and written as Oggs. How can I get my Banshee setup re-encoding the audio? If StackExchange supported bonus points, I'd give bonus points for a solution that only re-encoded music that was already losslessly encoded, but I don't think that's possible.

  • IIS to parse php in a .dll files

    - by Agony
    The .dll files ain't the dynamic link library. That's what the client side software calls for (cannot change). Its essentially a php script that should run and return specific values. However currently it simply downloads it and that results in a failure. That's what it results in on a Apache server: [Update] NewVersion=1 UpdateFileNumber=1 UpdateFile1=update1/LPServerInfo.dat ServerNumber=1 Server1=http://88.159.116.217/ here it is on IIS: 198.24.133.74:8080/update.dll?0 renaming it to php works fine for testing - it runs and returns values. I edited the MIME and set .dll to application/x-httpd-php but that doesn't seem to work in IIS. Any solutions?

  • What Would You Consider Best Practice Workflow Tools For Web Application (PHP) Development?

    - by Zenph
    I'm really hoping somebody with more experience can edit the question as per my examples of answers: • using version control • test driven development • debugging code (xdebug for php) • use of UML diagrams • use of OOP for maintainable, reusable code • use of frameworks (like Zend Framework for php) for rapid application development Anything else or an elaboration of what I mentioned above? Basically, I'm in the middle of forming a team of developers (I'm a developer myself) and I'd like some advice on how professional programmers/designers etc should work together and what standards/paradigms they should use. Also, if anybody has any books or links on the subject I'd welcome that! I did find this which I guess satisfies what I'm looking for, or at least part thereof: http://www.ibm.com/developerworks/websphere/library/techarticles/0306_perks/perks2.html

  • E-Commerce Website

    - by haargott
    I am planning to create an e-commerce website for users to buy products and services. In this website I want users to register and also participate in something like a browser game, where every user may receive some questions which they have to answer. For each question they successfully answered, they receive points and the number of collected points will decide on which rank they are. Edit 2 Currently I am considering using only HTML, CSS, JavaScript, PHP, SQL to design this e-commerce website. Together with this I was thinking about learning jQuery as it may help me, but I am not sure if I should code everything specifically by myself or just use the library to make it faster. 1) Could you tell me if those languages are sufficient enough for creating such a website described? 2) Could you tell me what kind of free software tools and frameworks are most appropriate to use when creating this e-commerce website?

  • Change the scale-policy of OpenGL ES in Android?

    - by wanting252
    I currently develop a game for Android in OpenGL ES 1.0, use libgdx library. I target the 720x480 screen size. For example, I design only one arts pack for 720x480. And what will happen in Android phones with screen-size smaller or bigger than it, 480x320 for instance? Could you please tell me how to change the scale-policy of OpenGL ES in Android? Or in libgdx specially? Is there anything like "Resample Image" like photoshop?(Nearest Neighbor, Bilinear, Bicubic etc..) for libgdx? Edit: I found some tutorials about texture filter in OpenGL, test it with Linear and Nearest. Linear is good for scaling but slow down the game, and Nearest is on the contrary. What should I do to get a balance between those?

  • Pooling (Singleton) Objects Against Connection Pools

    - by kolossus
    Given the following scenario A canned enterprise application that maintains its own connection pool A homegrown client application to the enterprise app. This app is built using Spring framework, with the DAO pattern While I may have a simplistic view of this, I think the following line of thinking is sound: Having a fixed pool of DAO objects, holding on to connection objects from the pool. Clearly, the pool should be capable of scaling up (or down depending on need) and the connection objects must outnumber the DAOs by a healthy margin. Good Instantiating brand new DAOs for every request to access the enterprise app; each DAO will attempt to grab a connection from the pool and release it when it's done. Bad Since these are service objects, there will be no (mutable) state held by the objects (reduced risk of concurrency issues) I also think that with #1, there should be little to no resource contention, while in #2, there'll almost always be a DAO waiting to be serviced. Is my thinking correct and what could go wrong?

  • How should I handle search engines auto-correcting the spelling of a site's name?

    - by Nathan G.
    A client's site and company is called 'Tranin Communications' (Tranin is her last name). It ranks well in searches for her name but rather poorly in searches for the name of her site/company. I realized that this is largely due to* search engines (Google especially) assuming that the query was misspelled and automatically including results for both 'train communications' and 'communications training'. Both of those queries yield many high-ranking sites that completely drown out hers. Sometimes Google even shows results for 'communications training' instead of 'tranin communications', hiding her site altogether. Is there a way to report an incorrect auto-correction to Google or something I can do to discourage this behavior (e.g. a meta tag)? My searches have come up cold, any suggestions would be appreciated. *I've come to this conclusion because her site ranks very highly when the same queries are put in quotes.

  • Can I set up a hostname alias that is only active in a specific network?

    - by denisw
    I have a small ARM box running ownCloud in my house, and a domain bound to my DSL router with Dynamic DNS. This works well as I can configure the ownCloud client to use the domain name, which works both in the house and when I'm on the road. However, at home I would like to let my laptop and my server talk to each other directly on the local network, rather than as if they were talking over the Internet (including DNS resolution for my domain name, routing all traffic through the DSL machinery etc.). I know that I can set a hostname alias for my domain in /etc/hosts - the problem is that I want this alias to only be active when I'm in the home network, while in all other cases DNS resolution should be used as normal. Is this possible?

  • Nonresponsive UI starting a few days ago; no obvious resource shortage

    - by user3679
    The mouse stops and moves jerkily, and sometimes won't register clicks. Gnome stopped responding a few hours ago--everything looks fine, but no clicks on menu items do anything. I've been running Ubuntu 10.10 since it was released; 8GB RAM and a 60GB SSD. I haven't added any hardware or software recently except the Ubuntu recommended updates; the last thing was the bitcoin client a week ago. top shows 3 CPU cores free and over a gig of ram left. I don't know what else to look at.

  • Want to use h264 in my commercial program. What steps should i take?

    - by Jason123
    Want to use h264 in my commercial program. What steps should I take? Here is what I see that needs to be done. I need to buy a license from VideoLan (x264licensing.com) to use the library to encode video into h264 format and I need to buy a license from the MpegLAGroup to use the h264 video encoding in general in my commercial product. Am I right in thinking that? How much do these cost? I don't see selling much since my target is very niche (video game screen capturing).

  • Is it possible to have my desktop loaded before login?

    - by Dims
    I am connecting to the system with Putty (this is Windows SSH client) then running some service in interactive personal mode. For example this is a script to run freeswitch: dims@nebulla:~$ cat freeswitch.sh #!/bin/sh cd ~/bin/freeswitch/bin gnome-terminal -e ./freeswitch & I.e. it is installed in user directory. Also DISPLAY is set to :0 The problem is that I can't use this script until login once. Script responds with dims@nebulla:~$ ./freeswitch.sh dims@nebulla:~$ No protocol specified Failed to parse arguments: Cannot open display: After login, I can do "Switch user" and see login screen but script will be able to run since desktop exists. My question is: is it possible to "preload" my desktop, so that initial situation was as if I loogged in and the went to switch user?

  • Implementing Command Pattern in Web Application

    - by KingOfHypocrites
    I'm looking to implement the command pattern in a web application (asp.net c#)... Since the commands come in text format from the client, what is the best way to translate the string to a command object? Should I use reflection? Currently I just assume the command that comes in matches the file name of a user control. This is a bit of a hack. Rather than have a select case statement that says if string = "Dashboard" then call Dashboard.Execute(), is there a pattern for working with commands that originate as strings?

  • Bumblebee optirun appears to depend on Intel

    - by user206398
    I have a Lenovo T420 with Intel and Nvidia graphics. On upgrade to Ubuntu Saucy, I had to purge and reinstall bumblebee-nvidia to get beyond optirun failing to find a GPU driver. Now, "optirun glxgears" and "optirun sol" succeed, but optirun fails on 2 Virtual Life viewers that it supported in the past, Cool VL (CoolVLViewer-1.26.8.34-Linux-x86) and Imprudence (Imprudence 1.4.0 beta2). In both cases, the error output is huge, but it starts with libGL error: failed to load driver: i965 and libGL error: failed to load driver: swrast From the little I can discover, i965 is an Intel graphics driver, which should not be invoked at all. I haven't found any information about swrast. I suspect that some of the X configuration associated with Bumblebee has some Intel dependence that is invoked on certain library calls, but not others. I haven't discovered any definite information on this line. The Cool VL Viewer runs without optirun, but complains about the insufficiency of the Intel graphics.

  • Will Google harm my ad's rating if my display URL in adwords does not exist?

    - by Jubbat
    I have a service in a very big city, and to make my ads stand out, I display the name of the neighborhood in the display URL, although the actual URL is always the same page with my services for any neighborhood. Will google decrease my rating for this? In a different note, you can also express your ideas about if it's sensible to do this or not, ie, the client might feel I'm deceiving them. Although this will be subjective, unless there is some scientific study. Thank you!

  • Can we ask idea of software?

    - by jailed abroad
    I am new to Programmers Stack Exchange. I have read the faq. I have a basic question here that can I ask about the idea of developing software. Just for sake of example, I have started a job in software house and my CEO hands me a project. And I have no idea or flow chart in my mind through which I would develop that application. For example client needs an E-diary. I have idea of WPF but lacking flow of app. So my question is can I ask about the app that "what would be the idea to develop the application"?

  • Le nouvel Hotmail pourra-t-il concurrencer Gmail ? Découvrez ses nouvelles fonctionnalités en détail

    Mise à jour du 19.05.2010 par Katleen Le nouvel Hotmail pourra-t-il concurrencer Gmail ? Découvrez ses nouvelles fonctionnalités en détails En matière de client mail, Microsoft est très en retard et part avec un gros handicap. Même si son service est celui qui compte le plus d'abonnés (majoritairement à cause de l'utilisation de Messenger), c'est aussi celui dont les utilisateurs sont le moins satisfait, face à un Gmail fonctionnel et sur, par exemple. La firme de Redmond a donc décidé de sortir l'artillerie lourde en remodelant totalement sa messagerie Hotmail. L'accent sera mis sur la sécurité, qui jusqu'ici laissait à désirer. Il sera désormais possible de s'authentifier grâce à des...

  • MSM Merge Modules in Visual Studio 2013 [on hold]

    - by theGreenCabbage
    Could someone please let me know where I might find resources for creating MSM files? While I am able to create MSI files using InstallShield, it seems that Visual Studio no longer supports Merge Module Projects, judging by the link below and the screenshot of my version of Visual Studio 2013 - http://msdn.microsoft.com/en-us/library/z6z02ts5(v=vs.80).aspx To create a new merge module project: On the File menu, point to Add, then click New Project. In the resulting Add New Project dialog box, in the Project types pane, open the Other Project Types node and select Setup and Deployment Projects. In the Templates pane, choose Merge Module Project.

  • IIS and content caching

    - by JayC
    I'm a web developer and administer of a Windows 2008R2 Could Instance with IIS 7. I recently made an update to our website, but when I revisited the website, the website was being viewed with old stylings. I did a refresh (shift + reload button in Firefox) and of course the website displayed as it should. I didn't worry about it, until my client had the same issue in Safari. So, my question, in general, is, how do I prevent this from happening again, and yet still afford some caching of our site? I noticed we did not have content expiration set up on our webserver sites, so I've set that up, but did I really need to? I've also looked at Etags, and, honestly, it's hard for me to know whether or not I should use them or not. One comment I read somewhere there isn't really any issue with Etags scenarios in IIS (even in webfarms)... but, I dunno. Anybody have any suggestions, links, info? Thanks.
