  • initializing hashes

    - by Paul
    Seems like I am frequently writing something like this... a_hash['x'] ? a_hash['x'] += ' some more text' : a_hash['x'] = 'first text' seems like there ought to be a better way, but I can't find it.

  • Javascript variables

    - by Uli
    I'm learning Javascript right now. Can anybody tell me why the second code block traces a empty path for -launch(this)- but using the first code block it gives me the right path? "<form action='"+launchwebsite+"/subsite/' method='post' target='_blank' onsubmit='launch(this)'>" and this not: "<a onclick='launch(this)' title='launch' class='iblack' /></a></div>" Best Uli

  • Jump to 'git add -i' patch command (5) directly

    - by felixge
    How can I get "git add -i" to start up in patch mode directly without having to type "5" + Enter? I know about "git add -p", but it's not the same as it doesn't show me a list of files to select from first. This is very annoying because I'd like to jump between "git add -i" and "git commit" very quickly to turn my dirty tree into some nice looking commits.

  • How to get "Friends who like/play games" list (similar to Farmville 2)

    - by FBAppDev
    I'm working on a Facebook app, and I'm trying to get a friends list similar to Farmville 2. They have a "friends who like games" list. My first thought is, I can get a list of all friends, then for each friend, see if they like any pages with type == "GAMES/TOYS". But ideally, I would like to get the list in one query (not by making one graph API or FQL request per friend). Is this possible, and if so, how?

  • Line up swing components by edges

    - by rasen58
    Is it possible to line up swing components? The components are in separate panels which both use flow layout. These two panels are in another panel which is using a grid layout. As you can see there is a subtle difference and I find it annoying. I know that all of the jlabels [the rectangles in blue/purple all have the same size, so i think it might be because of the '+' and '*', but I'm not sure because the left sides of the first two boxes aren't lined up. the panels JPanel panel2 = new JPanel(new GridLayout(4, 1)); JPanel panel2a = new JPanel(new FlowLayout()); JPanel panel2b = new JPanel(new FlowLayout()); the first two rectangles (purple) add1 = new JLabel("", JLabel.CENTER); add1.setTransferHandler(new TransferHandler("text")); add1.setBorder(b2); add2 = new JLabel("", JLabel.CENTER); add2.setTransferHandler(new TransferHandler("text")); add2.setBorder(b2); the two blue rectangles textFieldA = new JTextField(); textFieldA.setHorizontalAlignment(JTextField.CENTER); textFieldA.setEditable(false); textFieldA.setBorder(new LineBorder(Color.blue)); textFieldM = new JTextField(); textFieldM.setHorizontalAlignment(JTextField.CENTER); textFieldM.setEditable(false); textFieldM.setBorder(new LineBorder(Color.blue)); the + and * opA = new JLabel("+", JLabel.CENTER); opS = new JLabel("*", JLabel.CENTER); Showing that the rectangles are the same size Dimension d = card1.getPreferredSize(); int width = d.width + 100; int height = d.height + 50; add1.setPreferredSize(new Dimension(width, height)); add2.setPreferredSize(new Dimension(width, height)); mult1.setPreferredSize(new Dimension(width, height)); mult2.setPreferredSize(new Dimension(width, height)); textFieldA.setPreferredSize(new Dimension(width, height)); textFieldM.setPreferredSize(new Dimension(width, height)); Adding to the panels panel2a.add(add1); panel2a.add(opA); panel2a.add(add2); panel2a.add(enterA); panel2a.add(textFieldA); panel2c.add(mult1); panel2c.add(opM); panel2c.add(mult2); panel2c.add(enterM); panel2c.add(textFieldM); panel2.add(panel2a); panel2.add(panel2c);

  • Are cookies enough for storing login data? (PHP)

    - by jpjp
    I am reading the Head First PHP/Mysql book and they say to store both the user's username, email into cookies and sessions. Is it safe to assume that everyone know a day has cookies? Or should I store both in sessions and cookies? I am not storing any sensitive data in cookies such as password, etc.

    - by jason
    I am trying to do multiple counts everyone was working accept the first sub select (list1) I get an error that reads "Operand should contain 1 column(s)" i'm guessing it has something to do with the AND, but i'm not sure how I would fix this one. Select Count(list0.ustatus) AS finished_count, (Select list1.ustatus, Count(*) From listofupdates list1 Where list1.ustarted != '0000-00-00 00:00:00' AND list1.ustatus != 1) AS start_count, (Select Count(list2.udifficulty) From listofupdates list2 Where list2.udifficulty = 2) AS recheck_count, (Select Count(list3.udifficulty) From listofupdates list3 Where list3.udifficulty = 4) AS question_count From listofupdates list0 Where list0.ustatus = 1

  • insert exclusive locking

    - by Markus
    Hi, I have thought about the following SQL statements: INSERT INTO A(a1, a2) SELECT b1, udf_SomeFunc(b1) FROM B Where udf_SomeFunc makes a select on table A. As I understand, first, a shared lock is set on A (I am talking just about table A now), then, after this lock is released, an exclusive lock is obtained to insert the data. The question is: is it possible, that another transaction will get the exclusive lock on table A, just before the current transaction takes its exclusive lok on A?

  • Using ffmpeg to cut up video

    - by Neil
    I am using FFmpeg like this e.g.: ffmpeg -i input.wmv -ss 60 -t 60 -acodec copy -vcodec copy output.wmv to cut out a section of a large file. The -ss part works fine but the -t is ignored. That is, it correctly removes the first -ss seconds but then just keeps going to the end of the input with the copy. Is there a way to use FFmpeg to cut off the end of a video without recoding it?

  • Calling constructors in c++ without new

    - by Nils
    I've often seen that people create objects in C++ using Thing myThing("asdf"); Instead of Thing myThing = myThing("asdf"); This seems to work (using gcc), at least as long as there are no templates involved. My question now, is the first line correct and if so should I use it?

  • What are all the concurrent things [data structure, algorithm, locking mechanism] missing in .Net 3.

    - by user49767
    First time I am bit disappointed in StackOverflow cause my http://stackoverflow.com/questions/2571727/c-concurrency-vs-java-concurrency-which-is-neatly-designed-which-is-better question was closed. My intension was just trying to gather knowledge from programming guru's who worked in both the programming technologies. Rather closing this question, please help me by discussing what is good, bad, and ugly in multi-threading part in both the platforms. It is also welcome, if someone would like to compare with .Net 4.0 with JDK 6 (or JDK 7)

  • How can I set a default sort for tables in PHPMyAdmin (i.e. always "Primary key - Descending")

    - by jeremyclarke
    Even though its obnoxious in a lot of ways I use PHPMyAdmin all the time to debug database issues while writing PHP. By default it sorts tables by primary key ascending. 99% of the time I would rather have the newest data (my test data) shown at the top by default rather than the useless first few records ever saved. Is there a way to configure PHPMyAdmin to show the newest records by default? To alter similar behavior?

  • How to make every Class Method call a specified method before execution?

    - by norm
    I want to make my Python Class behave in such a way that when any Class method is called a default method is executed first without explicitly specifying this in the called Class. An example may help :) Class animals: def _internalMethod(): self.respires = True def cat(): self._internalMethod() self.name = 'cat' def dog(): self._internalMethod() self.name = 'dog' I want _internalMethod() to be called automatically when any method is called from an instance of animals, rather than stating it explicitly in the def of each method. Is there an elegant way to do this? Cheers,
