  • Use of putty in command line

    - by kij
    Hi, I'm trying to use putty in command line from an hudson job. The command is the following one: putty -ssh -2 -P 22 USERNAME@SERVER_ADDR -pw PASS -m command.txt Where 'command.txt' is a shell script to execute in the server through SSH. If i launch this command from the Window command prompt, it works, the shell script is executed on the server machine. If i launch a build of the hudson job configured with this batch command, it doesn't work. The build is running... and running... and running.. without doing anything, and i have to stop it manually. So my question is: Is it possible to launch an external programm (i.e. putty) from an hudson job ? ps: i tried SSH plugin but... not a really good plugin (pre/post build, fail status of the commands launched not caught by hudson, etc.) Thanks in advance for your help. Best regards. kij

  • split double in c wihout any libary

    - by DoomStone
    Hello I have a question for a c programmer out there, we have a tast at school to create a soft real time system in an operation system made by our teacher. Well that is all fine and dandy, we have chosen to create a system that calcuate how many unites of medicine a diabetic need based on his or hers blood sugar. It does not need to be correct just that we have the idea of a real time system :D But we have hit a little snag our formula for calculating the units of medicine is [blood sugar] * 1.2 But the only way we can send messages between processes is via a structure that contains 8 longs, but here is where my knowledge of c ends, we need for some way to split this double into 2 longs, example: the whole number in long 0 and the decimals in long 1 and then assemble it on the other side. But I have no idea who to do this, and therefore need a little help. We have tried but we do not have access to c standard libraries

  • ASP Force Download

    - by Thomas Clayson
    In PHP I can do: header("Content-type: application/octet-stream") and then anything that I output is downloaded instead of showing in the browser. Is there a similar way to do this in ASP? I have seen about all the file streaming and such using ADODB.Stream, but that doesn't seem to work for me and always requires another file to load the content from. Bit of an ASP noob, so go easy on me. :p All I want to do is have a script that outputs a CSV and that will force download instead of showing in the browser. Thanks EDIT here is my script currently: reportingForce.aspx.vb Public Class reportingForce Inherits System.Web.UI.Page Dim FStream Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Response.Buffer = True Response.ContentType = "application/octet-stream" Response.AddHeader("Content-disposition", "attachment; filename=" & Chr(34) & "my output file.csv" & Chr(34)) Response.Write("1,2,3,4,5" & vbCrLf) Response.Write("5,6,7,8,9" & vbCrLf) End Sub End Class reportingForce.aspx Hello,World

  • how to run href="#var=something" before onclick function fires in javascript?

    - by korben
    i'm using the below javascript to change an image on an aspx in asp.net c# <script language="JavaScript" type="text/javascript"> var updateImageWhenHashChanges = function() { theImage = document.getElementById("ctl00_ContentPlaceHolder1_Image1a"); if(window.location.hash == "#size=2") { theImage.src = "<%# Eval("realfilename", "/files/l{0}") %>"; } else if(window.location.hash == "#size=3") { theImage.src = "<%# Eval("realfilename", "/files/{0}") %>"; } else if(window.location.hash == "#size=1") { theImage.src = "<%# Eval("fullthumbname", "/thumbnails/{0}") %>"; } else { } } </script> here's how i call it with a link <a href="#size=3" onclick="updateImageWhenHashChanges();">test</a> the problem is that it only does what i'm expecting on the SECOND click of the link, because it seems onclick fires before the href, so the first time i'm just placing the var and the 2nd time i'm actually getting what i want. does anyone know how i can fix this? i'm trying to get the image to change on each click

  • How do you slow down the output from a DOS command

    - by JW
    I have lots of experience of writing php scripts that are run in the context of a webserver and almost no epxerience of writing php scripts for CLI or GUI output. I have used the command line for linux but do not have much expereince with DOS. Lets say I have php script that is: <?php echo('Hello world'); for ($idx = 0 ; $idx < 100 ; $idx++ ) { echo 'I am line '. $idx . PHP_EOL; } Then, I run it in my DOS Command prompt: # php helloworld.php Now this will spurt out the output quckly and i have to scroll the DOS command window up to see the output. I want to see the output one 'screen full' at a time. How do you do that from the perspective of a DOS user? Furthermore, although this is not my main main question, I would be also interested in knowing how to make the php script 'wait for input' from the command prompt.

  • Reference book on Ruby on Rails social network site for novices

    - by Christopher
    Hey, so I am a novice programmer who has only worked with HTML, CSS, and a touch of Java a couple of years ago. I am looking to try to get a social network site up and running on Ruby on Rails and was looking at RailsSpace: Building a Social Networking Website with Ruby on Rails (Addison-Wesley Professional Ruby Series) - Paperback (July 30, 2007) by Michael Hartl. This was published in 2007, however, and the newer reviews say it is not very helpful. Does anyone know if there are any new publications out there that walk you through building a social network site while teaching you the code(rather than just using a out of the box program)? Thanks

  • jquery draggable/droppable issue

    - by Scarface
    Hey guys I have a drag and drop function that does not fully work. What I want to do is be able to drag and drop a picture into a div and have that picture pop up in the div. I have a list of 2 pictures right now, so I have the following function echoed for each picture. Both pictures are draggable and droppable, but the first one is the only one that appears in the div, regardless of which picture gets dragged in. I am not sure what is wrong because the jquery function seems to be unique to each picture. If any one has any suggestions I would appreciate it greatly. while ($row = mysql_fetch_assoc($query)) { $image=htmlentities($row['image']); //image name $uniqid=uniqid(); //unique id for jquery functions $dirname = "usercontent/$user/images/$image"; echo "<img id=\"$uniqid\" src=\"$dirname\" width=\"75\" height=\"75\"/>"; echo "<script> $(function() { $(\"#$uniqid\").draggable({ scroll: true, scrollSensitivity: 10, scrollSpeed: 10, revert: true, helper: 'clone', cursorAt: { cursor: 'move', top: 27, left: 27 } }); $(\"#droppable2, #droppable-background , #droppable2-innerer\").droppable({ greedy: true, activeClass: 'ui-state-hover', hoverClass: 'ui-state-active', drop: function(event, ui) { $(this).addClass('ui-state-highlight').find('> p').html('Dropped!'); $('#droppable-background').css(\"background-image\",\"url($dirname)\"); } }); }); </script>"; }

  • looking for help with Flash sound to play on an iPad

    - by phm
    I hope you might be willing to help me. Years ago, when I was designing a game site, it was recommended to me to do what you pretty much suggested in your answer to a question about Flash sound: put my sound effects as Flash elements. This works great on every platform except the iPad. Do you have any idea what I should do? I'd really appreciate your help and you sound like a helpful person. Some people here can be kind of mean. I'm not a programmer by training, just self taught.

  • PHP mail() function not delivering mail

    - by Ryan Jones
    Hi there, I have a slight problem. I am using a working script (works on my testing account - shared server) to send a mail through PHP using the mail() function. I just got a dedicated server, and I haven't been able to get the function to work. I've spent the last 10 or so hours reading various documentations on BIND (for the SPF record), dovecot, sendmail and postfix trying various things to get this to work. There is clearly something that I am missing. So we know the PHP code works fine. All the headers are fine everything. We know this as it's a direct copy from my testing account. So the problem must arise somewhere in the server config. The path to sendmail is correct, and sendmail is (apparently) working fine. I've set up the script to now deliver "Sent" or "Error" based on the boolean result from the PHP mail() function. That is: if(mail($blah,$blah,$blah,$blah,$blah)) { echo "Sent"; } else { echo "Error";} And the result ALWAYS comes up as "Sent" - however, the email never arrives. Can someone suggest things to check, as I'm completely new to this (24 hours or so!). Thanks in advance. Ryan

  • JavaScript: Very strange behavior with assigning methods in a loop

    - by Andrey
    Consider this code below: <a href="javascript:void(-1)" id="a1">a1</a> <a href="javascript:void(-1)" id="a2">a2</a> <script type="text/javascript"> var buttons = [] buttons.push("a1") buttons.push("a2") var actions = [] for (var i in buttons) { actions[buttons[i]] = function() { alert(i) } } var elements = document.getElementsByTagName("a") for (var k = 0; k < elements.length; k++) { elements[k].onclick = actions[elements[k].id] } </script> Basically, it shows two anchors, a1 and a2, and I expect to see "1" and "2" popping up in an alert when clicking on corresponding anchor. It doesn't happen, I get "2" when clicking on either. After spending an hour meditating on the code, I decided that it probably happens because dynamic onclick methods for both anchors keep the last value of "i". So I change that loop to for (var i in buttons) { var local_i = i.toString() actions[buttons[i]] = function() { alert(local_i) } } hoping that each dynamic function will get its own copy of "i" with immediate value. But after this change I get "1" popping up when I click on either link. What am I doing wrong? It's a huge show stopper for me.

  • Problem with jQuery slider - time

    Hello. I'd like to make a slider to choose time(from 1:00 to 4:00) but it doesn't work. It doesn't communicate with 'select'.

  • How to maintain long-lived python projects w.r.t. dependencies and python versions ?

    - by Gyom
    short version: how can I get rid of the multiple-versions-of-python nightmare ? long version: over the years, I've used several versions of python, and what is worse, several extensions to python (e.g. pygame, pylab, wxPython...). Each time it was on a different setup, with different OSes, sometimes different architectures (like my old PowerPC mac). Nowadays I'm using a mac (OSX 10.6 on x86-64) and it's a dependency nightmare each time I want to revive script older than a few months. Python itself already comes in three different flavours in /usr/bin (2.5, 2.6, 3.1), but I had to install 2.4 from macports for pygame, something else (cannot remember what) forced me to install all three others from macports as well, so at the end of the day I'm the happy owner of seven (!) instances of python on my system. But that's not the problem, the problem is, none of them has the right (i.e. same set of) libraries installed, some of them are 32bits, some 64bits, and now I'm pretty much lost. For example right now I'm trying to run a three-year-old script (not written by me) which used to use matplotlib/numpy to draw a real-time plot within a rectangle of a wxwidgets window. But I'm failing miserably: py26-wxpython from macports won't install, stock python has wxwidgets included but also has some conflict between 32 bits and 64 bits, and it doesn't have numpy... what a mess ! Obviously, I'm doing things the wrong way. How do you usally cope with all that chaos ?

  • What tricks can be used to type and edit code faster?

    - by Thomas
    As Jeff Atwood noted, we are typists first, programmers second. Fast typing and editing may not be essential to be a good programmer, but it certainly helps. I noticed that I consciously and subconsciously use various tricks to get my intent across to the computer as fast as possible. What tricks can be used to type and edit code faster? I'm hoping to collect a nice list here that we can all learn from, so that we can be ever so slightly more productive. One trick per answer please! (This is not about typing speed in general. There are other questions about that. It's also not about general answers like "learn your editor's shortcut keys". Think of this topic as micro-optimizations for specific cases. See my own answers for examples of what I mean.)

  • Pass in a value into Python Class through command line

    - by chrissygormley
    Hello, I have got some code to pass in a variable into a script from the command line. The script is: import sys, os def function(var): print var class function_call(object): def __init__(self, sysArgs): try: self.function = None self.args = [] self.modulePath = sysArgs[0] self.moduleDir, tail = os.path.split(self.modulePath) self.moduleName, ext = os.path.splitext(tail) __import__(self.moduleName) self.module = sys.modules[self.moduleName] if len(sysArgs) > 1: self.functionName = sysArgs[1] self.function = self.module.__dict__[self.functionName] self.args = sysArgs[2:] except Exception, e: sys.stderr.write("%s %s\n" % ("PythonCall#__init__", e)) def execute(self): try: if self.function: self.function(*self.args) except Exception, e: sys.stderr.write("%s %s\n" % ("PythonCall#execute", e)) if __name__=="__main__": test = test() function_call(sys.argv).execute() This works by entering ./function <function> <arg1 arg2 ....>. The problem is that I want to to select the function I want that is in a class rather than just a function by itself. The code I have tried is the same except that function(var): is in a class. I was hoping for some ideas on how to modify my function_call class to accept this. Thanks for any help.

  • Problem using the prependTo() in jQuery

  • What benefits can Java developer have moving to a *NIX platform?

    - by dave-keiture
    Hi everyone, A friend of mine is a Java developer, who's using *NIX for ages. He claims that *NIX is for real Java geeks, whereas WIN is for dummies (and I'm one of them, according to him) and girls. When I ask him to argue his position, and explain, what's so good for Java developer on *NIX, he starts talking about console, wget, curl and grep. But sorry, wget and curl analogues exist for the WIN platform as well. As for the console - I'm using FAR Commander, and have access to the command line when I need. Moreover, even if I decide moving to *NIX, I will certainly use Netbeans or Eclipse there, so there will be no big difference. Guys, who use Java on *NIX, could you please give me a real killer examples, when *NIX (any util or technique) dramatically increases Java development productivity (in the way the hints are given in "The Pragmatic Programmer"), or, which is also important, gives more fun from the process. Thanks in advance!

  • How can I define an empty array in a Perl construtor?

    - by Laimoncijus
    I am just beginner with Perl, so if it sounds stupid - sorry for that :) My problem is - I am trying to write a class, which has an empty array, defined in constructor of a class. So I am doing this like this: package MyClass; use strict; sub new { my ($C) = @_; my $self = { items => () }; bless $self, ref $C || $C; } sub get { return $_[0]->{items}; } 1; Later I am testing my class with simple script: use strict; use Data::Dumper; use MyClass; my $o = MyClass->new(); my @items = $o->get(); print "length = ", scalar(@items), "\n", Dumper(@items); And while running the script I get following: $ perl my_test.pl length = 1 $VAR1 = undef; Why am I doing wrong what causes that I get my items array filled with undef? Maybe someone could show me example how the class would need to be defined so I would not get any default values in my array?

  • Changing <object> height and width works in Chrome but not Firefox or IE. Why?

    - by Michael Hopkins
    I am making a site with two Youtube videos. These videos use the raw embed code from Youtube. The site's design doesn't work with any of the default Youtube sizes, so I am writing code to automatically resize the video. Here is my code. There will never be more than these two tags on the page, otherwise I'd do a better job selecting the videos. <script language='JavaScript' type='text/javascript'> var x=document.getElementsByTagName('object'); x.[0].width='350'; x.[0].height='350'; x.[1].width='350'; x.[1].height='350'; </script> For reference, here's a sample default Youtube embed that the code might alter: <object width="480" height="385"> <param name="movie" value="http://www.youtube-nocookie.com/v/zSgiXGELjbc&hl=en_US&fs=1&rel=0"></param> <param name="allowFullScreen" value="true"></param> <param name="allowscriptaccess" value="always"></param> <embed src="http://www.youtube-nocookie.com/v/zSgiXGELjbc&hl=en_US&fs=1&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed> </object> In Chrome, the video players sit perfectly in a 350x350 box. In IE and FF (latest versions), the videos are the unchanged, normal size. I cannot find anything in Google that explans why this won't work. I have tried using setattribute, for loops, adjusting both and , single-quotes and double-quotes, etc. Any ideas what is going wrong?
