Around (before part) Before Method itself After Around (after part)

  • Nashorn in the Twitterverse

    - by jlaskey
    I have been following how often Nashorn has been showing up on the net.  Nashorn got a burst of tweets when we announced Project Nashorn and I was curious how Nashorn was trending per day, maybe graph the result.  Counting tweets manually seemed mindless, so why not write a program to do the same. This is where Nashorn + Java came shining through.  There is a very nice Java library out there called Twitter4J https://github.com/yusuke/twitter4j that handles all things Twitter.  After running bin/getAccessToken.sh to get a twitter4j.properties file with personal authorization, all I had to do to run my simple exploratory app was; nashorn -cp $TWITTER4J/twitter4j-core-3.0.1.jar GetHomeTimeline.js The content of GetHomeTimeline.js is as follows; var twitter4j      = Packages.twitter4j; var TwitterFactory = twitter4j.TwitterFactory; var Query          = twitter4j.Query; var twitter = new TwitterFactory().instance; var query   = new Query("nashorn OR nashornjs"); query.count = 100; do {     var result = twitter.search(query);     var tweets = result.tweets;     for each (tweet in tweets) {         print("@" + tweet.user.screenName + "\t" + tweet.text);     } } while (query = result.nextQuery()); How easy was that?  Now to hook it up to the JavaFX graphing library...

  • TPC-H Benchmarks on SQL Server 2014 with Columnstore

    - by jchang
    Three TPC-H benchmark results were published in April of this year at SQL Server 2014 launch, where the new updateable columnstore feature was used. SQL Server 2012 had non-updateable columnstore that required the base table to exist in rowstore form. This was not used in the one published TPC-H benchmark result on SQL Server 2012, which includes two refresh stored procedures, one inserting rows, the second deleting rows. It is possible that the TPC-H rules do not allow a view to union two tables?...(read more)

  • I get an "serious errors while checking the disk drives for /boot" error while booting

    - by Vaios Argiropoulos
    I have just set up my new system by creating three partitions on a whole hard disk (/boot,/home,swap and /(root)) .I saw this article and now i am getting those errors and the system provide me with some options (I to ignore, S to skip mounting or M for manual recovery). I am forced to choose skip mounting because i don't know what manual recovery is. Despite the error i get i think that the system boots ok because i can use the system but this error is very annoying.

  • How to interpret Events from Unique Events in Google Analytics?

    - by Mike Buckbee
    I'm trying to add some javascript triggered Google Analytics events to a website that is already working with GA. I've included the following beneath the standard GA script (new ga.js script). _gaq.push(['_trackEvent', 'Downloads', 'Extension']); Which seems to be working ok, but the results listed in the Events Overview report (after waiting 24 hours), don't make sense. It states that there have been 1 Total Events and 5 Unique Events (screenshot below). https://img.skitch.com/20110729-8hufapcq2366rq3cbpuihjgqjd.jpg

  • Will YouTube (or any video hosting service) provide a mp4 link to an uploaded video? [closed]

    - by DoubleJ
    I've looked into a number of video hosting options, but none seem to provide a .mp4 link to your uploaded video, which I require for use in a project using BigVideo.js. The only service I've found to provide this functionality so far is VimeoPro, which I can't afford. Is there any way to do this for free in YouTube? Or, otherwise, are there any other (preferably low- or no-cost) video hosting providers that will provide a .mp4 link?

  • Website File and Folder Structure

    - by Drummss
    I am having a problem learning how proper website structure should be. And by that I mean how to code the pages and how folder structure should be. Currently I am navigating around my website using GET variables in PHP when you want go to another page, so I am always loading the index.php file. And I would load the page I wanted like so: $page = "error"; if(isset($_GET["page"]) AND file_exists("pages/".$_GET["page"].".php")) { $page = $_GET["page"]; } elseif(!isset($_GET["page"])) { $page = "home"; } And this: <div id="page"> <?php include("pages/".$page.".php"); ?> </div> The reason I am doing this is because it makes making new pages a lot easier as I don't have to link style sheets and javascript in every file like so: <head> <title> Website Name </title> <link href='http://fonts.googleapis.com/css?family=Lato:300,400' rel='stylesheet' type='text/css'> <link rel="stylesheet" href="css/style.css" type="text/css"> <link rel="shortcut icon" href="favicon.png"/> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js" type="text/javascript"></script> <script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js" type="text/javascript"></script> </head> There is a lot of problems doing it this way as URLs don't look normal ("?page=apanel/app") if I am trying to access a page from inside a folder inside the pages folder to prevent clutter. Obviously this is not the only way to go about it and I can't find the proper way to do it because I'm sure websites don't link style sheets in every file as that would be very bad if you changed a file name or needed to add another file you would have to change it in every file. If anyone could tell me how it is actually done or point me towards a tutorial that would be great. Thanks for your time :)

  • Which tool can tidy/indent HTML5?

    - by user2534
    I've already spent about 2 hours searching google and trying various tools but either they don't do indent tags per say or they aren't HTML5 compatible such as the famous HTML tidy which was last updated 3 years ago… N.B. I don't want to apply this to the source of a page (like PHP or JS would do) but to the code in the editor so that a clear hierarchy appears between tags. Ideally I'd like a Mac OS X tool but I'll take any online tool and in last resot a Wine compatible one. P.S. at the moment I use Coda from Panic

  • What do you do when working with multiple languages with different capitalization schemes?

    - by dvcolgan
    I'm making a webapp using Django. The Python convention for naming variables is lowercase_with_underscores, but the Javascript convention is camelCase. In addition, I've seen many people use lowercase-with-hyphens for CSS identifiers. Would you suggest using all three naming conventions where appropriate, or picking one and using it, even if the other two recommend something else? Switching back and forth isn't a huge problem, but it can still be mental overhead.

  • Should the test and the fix be written by different people?

    - by Nutel
    There is a common practice in TDD to write a test before fix to avoid regression and simplify fixing. I just wonder what if the test and fix will be written by different people, total spent time will be almost the same but as now three people will think about possible failures (+tester) we increase probability that fix will cover all possible failure scenarios. Does this practice make sense or it will just waste additional time needed for one more person to familiarize with bug?

  • Computer Engineer in CS Interview

    - by blasteye
    As a Computer Engineering student, while in school I've primarily dealt with C, Matlab, and VHDL. On my own though, i learned a bit about OOP (Polymorphism, inheritance, encapsulation), and have done quite a bit of web development using JavaScript/PHP/Node.js While at coding interviews I've be asked academia CS questions such as "abstract vs interface". The problem is that I didn't know the official terminology, but I have dealt with this type of programming decisions/concepts. Could anyone recommend a good resource for me to learn these academia CS terms?

  • How are people using virtualisation with SQL Server? Part 1

    - by GavinPayneUK
    Allow me to share with you the results of a survey I did about how people are using virtualisation with SQL Server. This is a three part series of articles sharing the results. In December 2010 I did a 10 question survey to see how people were using virtualisation with SQL Server and if they were changing their deployment and management processes as a result. 21 people responded from at least Europe, the US and Asia Pac. It’s not a massive number but it was large enough to see some trends and some...(read more)
