  • How can be changed the linux system's default character set?

    - by JPCF
    Hi, I'm working in a software development team using svn. Since many developer's computers are working using windows, text file codification has to be agreed with everyone. I decided to use Linux, and probably I will have to change my machine's default character codification. How can this be done in Linux? Thanks

  • How to define default values optional fields in play framework forms?

    - by natalinobusa
    I am implementing a web api using the scala 2.0.2 play framework. I would like to extract and validate a number of get parameters. And for this I am using a play "form" which allows me to define optional fields. Problem: For those optional fields, I need to define a default value if the parameter is not passed. The code is intended to parse correctly these three use cases: /test?top=abc (error, abc is not an integer) /test?top=123 (valid, top is 123) /test (valid, top is 42 (default value)) I have come up with the following code: def test = Action { implicit request => case class CData(top:Int) val p = Form( mapping( "top" -> optional(number) )((top) => CData($top.getOrElse(42))) ((cdata:CData) => Some(Some(cdata.top))) ).bindFromRequest() Ok("all done.") } The code works, but it's definitely not elegant. There is a lot of boiler plate going on just to set up a default value for a missing request parameter. Can anyone suggest a cleaner and more coincise solution?

  • Is there a way to change the default animation speed in PowerPoint?

    - by Tim
    I do a lot of PowerPoint (2007) presentations, and some of those involve some rather complex diagrams that I like to build step by step, using PowerPoint's animation feature. I prefer using the "fade in" style, but I find the default medium speed setting too low, so every time I'm adding an element to my animation, I have to go to the Speed dropdown box and select "Very fast". This is getting annoying, so I wonder if there is a way to tell PowerPoint that I'd like my standard animation speed (at least for fade-ins) to be "very fast"?

  • How to stop Outlook 2010 from registering itself as the default email client over and over again?

    - by Tobias Kienzler
    I'm usually using Thunderbird, but for testing purposes have to start Outlook every now and then. Afterwards, Thunderbird informs me that it is no longer the default client, which it should have remained. How to stop Outlook 2010 from being so insolent? edit In fact, Outlook does not change any of the settings I checked so far (it doesn't re-register files, and mailto: links still open Thunderbird, so I'm rather confused at what Thunderbird considers to be modified by Outlook

  • How do I set default group ownership for files in a directory?

    - by tnichols
    I am running a cakephp webapp on Linode LAMP. I am finding that my temp files are created with root:root ownership. But the webapp is running with Apache's permissions (www-data). This causes warnings any time there is a new file created because it is not writable for user www-data. How do I change the default ownership to www-data on any new files created in the temp folder? Thanks for your help!

  • Object inside of array -- works in one scope but not in another?

    - by Earlz
    Ok I've been learning some of the more advanced aspects of Javascript and now trying to use this I'm stuck. Here is my code: function Data(){} function init(state){ var item; item=new Data(); item.fieldrid=17; item.description='foo'; state.push(item); }; function findInState(state,fieldrid) { for (var item in state) { alert(item.fieldrid); //prints undefined if (item.fieldrid == fieldrid) { return item; } } return null; } var s=[]; init(s); alert(s[0].fieldrid); //prints 17 (expected) alert(findInState(s,17).fieldrid); //exception here. function returns null. A running example is here at jsbin Why does this not work? I would expect the alert in findInState to yield 17 but instead it yields undefined. What am I doing wrong?

  • How to set default view in OpenLayers, WITHOUT restricting bounds?

    - by Jenny
    Based on samples, I can see that you can set a default view in OpenLayers by saying something along the lines of: var bounds = new OpenLayers.Bounds(-125, 25, -65, 50); var map = new OpenLayers.Map('map', {restrictedExtent: bounds }); However, this also (as the name implies), restricts me to be able to ONLY navigate within these bounds. I can zoom out and see things outside of these bounds, but I can't then zoom back onto them, or scroll to them. I've tried not having any restrictedExtent (or making it the entire map), but then I can't get it to focus on the area I want. I tried using: map.setCenter(new OpenLayers.LonLat(0,0), 3); console.log(map.getCenter()); To set the zoom and the center...but it doesn't seem to do ANYTHING, other than set the variable "center" which I can then read from map.getCenter() (if I don't set it, it's null, if I do set it, I can see it...but the map itself stays fully extended and it's center doesn't seem to change at all...) The Map layer I am using is: OpenLayers.Layer.OSM.Mapnik with displayOutsideMaxExtent set to true... I'm really at a loss here. My goal is to have a default region of the world zoomed in to and in view (such as the United States), with the option of viewers being able to go outside the default to view things.

  • Can I increase the scope of 'this' in the following example?

    - by Stomped
    In using a jquery callback, I found that 'this' isn't defined anymore. I've found a work around, which is to set 'this' to another variable. For example, like so: function handler(DATA) { myThis = this; $.post( 'file.php', DATA, function() { // THIS where I need access to 'this', but its not available // unless I've used the 'myThis' trick above } ); } It works like this, but I am always looking for 'the right way' or 'the better way' to do things. Is this the best way? or is there another?

  • QLocale, what is the scope of the global QLocale::setDefault()?

    - by ALoopingIcon
    Problem: I have a QT based multiplatform (win,mac,*nix) application that parses ascii files containing decimal numbers. parsing is done using a variety of different code pieces that use anything from qt string stuff, c++ stdin, oldstyle scanf, etc. ascii files have always the '.' (dot) as separated decimal (e.g. in the file to be parsed 1/10 is written 0.1 as standard in many countries). people using the application within a OS localized for using comma separated decimal encounter a lot of problems (e.g. for french users scanf expect to find 0,1 as a valid textual representation of 1/10 and if they find 0.1 scanf will parse it as 0) How can I be sure that the OS Locale indication of how decimal point has to be written is always ignored? Is it safe assuming that adding QLocale::setDefault(QLocale(QLocale::English,QLocale::UnitedStates)); is enough to get rid of all these problems? Any suggestion for portable ways of setting the locale globally?

  • Is it possible to change or override the default keyboard shortcuts in Finder?

    - by super
    I would like to override the keyboard-shortcut for a particular built-in action in finder (OS X 10.6.7). An example would be to override the Cmd+N for a New Finder Window to some other action, say Open a blank Text document. I can create the service for opening a blank Text document in automator - and I can map a new keyboard shortcut for this - but the new keyboard shortcut will not override a default keyboard shortcut. I do not want to install any 3rd party applications (like QuickSilver).

  • Is a string formatter that pulls variables from its calling scope bad practice?

    - by Eric
    I have some code that does an awful lot of string formatting, Often, I end up with code along the lines of: "...".format(x=x, y=y, z=z, foo=foo, ...) Where I'm trying to interpolate a large number of variables into a large string. Is there a good reason not to write a function like this that uses the inspect module to find variables to interpolate? import inspect def interpolate(s): return s.format(**inspect.currentframe().f_back.f_locals) def generateTheString(x): y = foo(x) z = x + y # more calculations go here return interpolate("{x}, {y}, {z}")

  • How can I get a default value in some instances but not others?

    - by Connor Wagner
    I am making an iPhone app and want to use an 'if' statement and a boolean to set default values in some instances but not others... is this possible? Are there alternative options if it is not possible? In the MainViewController.m I have: @interface MainViewController (){ BOOL moveOver; } [...] - (void)viewDidLoad { [super viewDidLoad]; _label.text = [NSString stringWithFormat:@"%i", computerSpeed]; } } [...] - (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller { [self dismissViewControllerAnimated:YES completion:nil]; moveOver = true; } The problem that it is redefined when the ViewDidLoad runs... I need a statement that will not redefine when the ViewDidLoad runs. I have something that I feel like is much closer to working... In the ViewDidLoad I have: if (playToInt != 10 || computerMoveSpeed != 3) { moveOver = TRUE; } which connects to my created method, gameLoop. It has if (moveOver == false) { computerMoveSpeed = 3; playToInt = 10; } I have tried putting the code in the gameLoop into the ViewDidLoad, but it had the same effect. When moveOver was false, the computerMoveSpeed and the playToInt were both seemingly 0. I have two UITextFields and typed 10 and 3 in them... does this not set it to the default? It seems to set the default to 0 for both, how do I change this? THIS IS A DIFFERENT ISSUE THAN THE THREE BOOLEAN VALUES QUESTION

  • How can I define the search scope by "this week" meaning Monday - Friday in Ruby on Rails?

    - by Angela
    This is an extension of an earlier question. I realized, what I really want is to go to a URL /report/thisweek and it will do a .find (or named_scope) across contact_emails.date_sent where date_sent is between MONDAY and FRIDAY of the week to which Date.today belongs. In other words, if today is THURSDAY, it will do a search for all emails MONDAY through THURSDAY of this week. Not sure if this is doable or makes sense, but I think that's what I'd ultimately am trying to do. Thanks!

  • Route forwarded traffic through eth0 but local traffic through tun0

    - by Ross Patterson
    I have a Ubuntu 12.04/Zentyal 2.3 server configured with WAN NATed on eth0, local interfaces eth1 and wlan0 bridged on br1 on which DHCP runs, and an OpenVPN connection on tun0. I only need the VPN for some things running on the gateway itself and I need to make sure that everything running on the gateway goes through the VPNs tun0. root:~# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default gw... 0.0.0.0 UG 100 0 0 eth0 link-local * 255.255.0.0 U 1000 0 0 br1 192.168.1.0 * 255.255.255.0 U 0 0 0 br1 A.B.C.0 * 255.255.255.0 U 0 0 0 eth0 root:~# ip route 169.254.0.0/16 dev br1 scope link metric 1000 192.168.1.0/24 dev br1 proto kernel scope link src 192.168.1.1 A.B.C.0/24 dev eth0 proto kernel scope link src A.B.C.186 root:~# ip route show table main 169.254.0.0/16 dev br1 scope link metric 1000 192.168.1.0/24 dev br1 proto kernel scope link src 192.168.1.1 A.B.C.0/24 dev eth0 proto kernel scope link src A.B.C.D root:~# ip route show table default default via A.B.C.1 dev eth0 How can I configure routing (or otherwise) such that all forwarded traffic for other hosts on the LAN goes through eth0 but all traffic for the gateway itself goes through the VPN on tun0?
