  • How to block a website completely?

    - by user37076
    I want to block some sites(e.g. youtube,news sites ), because I have a problem with procrastination and I find these websites affect my productivity very much. I used to block them by adding them to HOSTS file. However, gradually every time I want to take a break, I open the hosts file and comment my block again. Is there any way I can block the websites and cannot (at least a little bit hard, e.g. I have to reboot my pc) unblock them. I have no access to the router or any firewall, besides the ones on my computer. I just want to FORCE myself to work without any chance to procrastinate.

  • Execution sequence inside a jquery event handler

    - by user576358
    I have a big issue with the execution squence inside this jquery handler : Was wondering if anyone has come accross this before: I have a simple form: <form action='foo.cgi' id='myForm' > <input type=text name='name' /> <input type=submit value='Find it!'/> </form> when user clicks on Find it! would like to change the cursor to 'progress' before the data is returned through an ajax call: $(document).ready(function(){ $("#myForm ").submit(function(){ $("body").css("cursor", "progress") ; htmlobj=$.ajax({url:server_url,..........); } } However: The cursor [line 2 above ] does not change until data is returned through ajax - Seems like line 3. gets executed before 2. Any help is greatly appreciated

  • Why are some strings displayed as garbage when I scroll my read-only multiline Win32 edit control ve

    - by sharptooth
    In my native C+ Win32 GUI application I have a property sheet with two property pages. One of the property pages contains an edit box: EDITTEXT IDC_EDIT_ID,x,y,width,height,ES_MULTILINE | ES_READONLY | NOT WS_BORDER | WS_VSCROLL | WS_HSCROLL | NOT WS_TABSTOP,WS_EX_STATICEDGE I set a multiline text to this edit box. The text has more lines than the edit can fit, so some of the text is clipped and a vertical scroll bar appears. When I scroll up with the mouse the lines that come "from under clip area" are drawn as garbage - it looks like first one line is drawn, then some other line is drawn on the same place without first painting the background. The lines that just move up - ones that were visible before scrolling and remain visible after scrolling are displayed allright. What's the reason and workaround for this behavior?

  • I can't find a DirectX installer to run from my installer.

    - by John
    I tried this one. But it's the annoying one which asks you where to extract temp files, my users won't know what this means. I also tried the web installer, but you're not strictly allowed to use this. I don't really follow the windows setup stuff, but is there a single .EXE I am allowed to distribute and run, which just works (for DX 9.0C) with some command-line args? Or some other way, which can can described in idiot-proof steps and and called in one command-line argument from an installer script like Inno?

  • Python: Check if all dictionaries in list are empty

    - by Brant
    I have a list of dictionaries. I need to check if all the dictionaries in that list are empty. I am looking for a simple statement that will do it in one line. Is there a single line way to do the following (not including the print)? l = [{},{},{}] # this list is generated elsewhere... all_empty = True for i in l: if i: all_empty = False print all_empty Somewhat new to python... I don't know if there is a shorthand built-in way to check this. Thanks in advance.

  • How to extract a submatrix from a matrix .. ?

    - by ZaZu
    Hello, I have a matrix in a txt file and I want to load the matrix based on my input of number of rows and columns For example, I have a 5 by 5 matrix in the file. I want to extract a 3 by 3 matrix, how can I do that ? I created a nested loop using : FILE *sample sample=fopen("randomfile.txt","r"); for(i=0;i<rows;i++){ for(j=0;j<cols;j++){ fscanf(sample,"%f",&matrix[i][j]); } fscanf(sample,"\n",&matrix[i][j]); } fclose(sample); Sadly the code does not work .. If I have this matrix : 5.00 4.00 5.00 6.00 5.00 4.00 3.00 25.00 5.00 3.00 4.00 23.00 5.00 2.00 352.00 6.00 And inputting 3 for rows and 3 for columns, I get : 5.00 4.00 5.00 6.00 5.00 4.00 3.00 25.00 5.00 Which is obviously wrong , its reading line by line rather than skipping the unmentioned column ... What am I doing wrong ? Thanks !

  • Compare images to find differences

    - by _simon_
    Task: I have a camera mounted on the end of our assembly line, which captures images of produced items. Let's for example say, that we produce tickets (with some text and pictures on them). So every produced ticket is photographed and saved to disk as image. Now I would like to check these saved images for anomalies (i.e. compare them to an image (a template), which is OK). So if there is a problem with a ticket on our assembly line (missing picture, a stain,...), my application should find it (because its image differs too much from my template). Question: What is the easiest way to compare pictures and find differences between them? Do I need to write my own methods, or can I use existing ones? It would be great if I just set a tolerance value (i.e. images can differ for 1%), put both images in a function and get a return value of true or false :) Tools: C# or VB.NET, Emgu.CV (.NET wrapper for OpenCV) or something similar

  • jQuery .find() doesn't return data in IE but does in Firefox and Chrome

    - by Steve Hiner
    I helped a friend out by doing a little web work for him. Part of what he needed was an easy way to change a couple pieces of text on his site. Rather than having him edit the HTML I decided to provide an XML file with the messages in it and I used jQuery to pull them out of the file and insert them into the page. It works great... In Firefox and Chrome, not so great in IE7. I was hoping one of you could tell me why. I did a fair but of googling but couldn't find what I'm looking for. Here's the XML: <?xml version="1.0" encoding="utf-8" ?> <messages> <message type="HeaderMessage"> This message is put up in the header area. </message> <message type="FooterMessage"> This message is put in the lower left cell. </message> </messages> And here's my jQuery call: <script type="text/javascript"> $(document).ready(function() { $.get('messages.xml', function(d) { //I have confirmed that it gets to here in IE //and it has the xml loaded. //alert(d); gives me a message box with the xml text in it //alert($(d).find('message')); gives me "[object Object]" //alert($(d).find('message')[0]); gives me "undefined" //alert($(d).find('message').Length); gives me "undefined" $(d).find('message').each(function() { //But it never gets to here in IE var $msg = $(this); var type = $msg.attr("type"); var message = $msg.text(); switch (type) { case "HeaderMessage": $("#HeaderMessageDiv").html(message); break; case "FooterMessage": $("#footermessagecell").html(message); break; default: } }); }); }); </script> Is there something I need to do differently in IE? Based on the message box with [object Object] I'm assumed that .find was working in IE but since I can't index into the array with [0] or check it's Length I'm guessing that means .find isn't returning any results. Any reason why that would work perfectly in Firefox and Chrome but fail in IE? I'm a total newbie with jQuery so I hope I haven't just done something stupid. That code above was scraped out of a forum and modified to suit my needs. Since jQuery is cross-platform I figured I wouldn't have to deal with this mess. Edit: I've found that if I load the page in Visual Studio 2008 and run it then it will work in IE. So it turns out it always works when run through the development web server. Now I'm thinking IE just doesn't like doing .find in XML loaded off of my local drive so maybe when this is on an actual web server it will work OK. I have confirmed that it works fine when browsed from a web server. Must be a peculiarity with IE. I'm guessing it's because the web server sets the mime type for the xml data file transfer and without that IE doesn't parse the xml correctly.

  • How to port C# code which uses a callback to VB.NET?

    - by Bob
    I need to port the following from the ASP.NET MVC 2 sourcecode from C# to VB.NET. It's from AuthorizeAttribute.cs beginning on line 86: HttpCachePolicyBase cachePolicy = filterContext.HttpContext.Response.Cache; cachePolicy.SetProxyMaxAge(new TimeSpan(0)); cachePolicy.AddValidationCallback(CacheValidateHandler, null /* data */); where CacheValidateHandler is: private void CacheValidateHandler(HttpContext context, object data, ref HttpValidationStatus validationStatus) { validationStatus = OnCacheAuthorization(new HttpContextWrapper(context)); } The VB.NET port from http://converter.telerik.com doesn't quite work for this line: cachePolicy.AddValidationCallback(CacheValidateHandler, Nothing) ' Error where CacheValidateHandler is: Private Sub CacheValidateHandler(ByVal context As HttpContext, ByVal data As Object, _ ByRef validationStatus As HttpValidationStatus) validationStatus = OnCacheAuthorization(New HttpContextWrapper(context)) End Sub VS2008 complains that CacheValidateHandler does not specify its arguments for context, data, and validationStatus. Any ideas how to port this code?

  • How to clone a model's attributes easily?

    - by Zabba
    I have these models: class Address < ActiveRecord::Base belongs_to :event attr_accessible :street, :city validates :street, :city, :presence => true end class Event < ActiveRecord::Base has_one :address accepts_nested_attributes_for :address end If I do the below assignment in the Events create action and save the event I get an error: #Use the current user's address for the event @event.address_attributes = current_user.address.attributes #Error occurs at the above mentioned line ActiveRecord::RecordNotFound (Couldn't find Address with ID=1 for Event with ID=) I think what's happening is that all the address's attributes (including the primary key) is getting assigned in the @event.address_attributes = line. But all I really want is the "real data" (street, city), not the primary keys or created_at etc to get copied over. I suppose I could write a small method to do this sort of selective copy but I can't help but feel there must be some built-in method for this? What's the best/right way to do this?

  • Word Wrap in Vim (preserving indentation)

    - by sixtyfootersdude
    I was just looking at this post which describes how to wrap entire words in vim. The accepted solution was this: :set formatoptions=l :set lbr Which takes this text (tabs are shown as \t): *Inside of window *Outside of window |---------------------------------------| |\t\tthis is a like of text that will wr|ap here |\t\tcan you see the wrap | | | |---------------------------------------| This accomplishes a behavior like this (tabs are shown as \t): *Inside of window *Outside of window |---------------------------------------| |\t\tthis is a like of text that will | |wrap here | |\t\tcan you see the wrap | | | |---------------------------------------| I would however like to redefine this function. I would like the wrapped line to have the same number of tabs in front of it that the line above has plus one. Ie: *Inside of window *Outside of window |---------------------------------------| |\t\tthis is a like of text that will | |\t\t\twrap here | |\t\tcan you see the wrap | | | |---------------------------------------| Any ideas?

  • Creating a PHP web page that enables you to reboot the server in Linux?

    - by Stuart
    I want to create a web page that allows the user to initiate a reboot on the linux server. Obviously this would only be avaliable for system admins and would also be controlled by using iptables. Below is a sample of code that I was thinking of using but I wanted to know if there is another way to do this and how also to use this in a web page? Also is there any thing else that I should consider? $command = "cat $pass | su -c 'shutdown -r now'"; $output = array(); try{ echo shell_exec($command); exec($command, $output); system($command, $output); } catch(Exception $e) { print "Unable to shutdown system...\n"; } foreach ($output as $line) { print "$line<br>"; } Thanks in advance.

  • Sleeping a thread blocking stdin

    Hey, I'm running a function which evaluates commands passed in using stdin and another function which runs a bunch of jobs. I need to make the latter function sleep at regular intervals but that seems to be blocking the stdin. Any advice on how to resolve this would be appreciated. The source code for the functions is def runJobs(comps, jobQueue, numRunning, limit, lock): while len(jobQueue) >= 0: print(len(jobQueue)); if len(jobQueue) > 0: comp, tasks = find_computer(comps, 0); #do something time.sleep(5); def manageStdin(): print "Global Stdin Begins Now" for line in fileinput.input(): try: print(eval(line)); except Exception, e: print e; --Thanks

  • Firing events in script task

    - by Anonymouslemming
    I've got an SSIS project where I am constructing an SQL command based on some variables. I'm constructing the command in a script task, and want to output the constructed SQL to the 'Execution Results' window. I am trying to do this using a FireInformation line from inside my script as follows: Dts.Events.FireInformation(99, "test", "Make this event appear!", "", 0, true); However, in the script editor when editing ScriptMain.cs, that line is underlined in red, and on mouseover, I get the following message: Error: The best overloaded method match for 'Microsoft.SqlServer.Dts.Tasks.ScriptTask.EventsObjectWrapper.FireInformation(int, string, string, string, int, ref bool') has some invalid arguments As a result, my script does not compile and I cannot execute it. Any idea what I'm doing wrong here, or what I need to change to be able to see the values of my variables at this point in the Execution output?

  • parsing position files in ruby

    - by john
    I have a sample position file like below. 789754654 COLORA SOMETHING1 19370119FYY076 2342423234SS323423 742784897 COLORB SOMETHING2 20060722FYY076 2342342342SDFSD3423 I am interested in positions 54-61 (4th column). I want to change the date to be a different format. So final outcome will be: 789754654 COLORA SOMETHING1 01191937FYY076 2342423234SS323423 742784897 COLORB SOMETHING2 07222006FYY076 2342342342SDFSD3423 The columns are seperated by spaces not tabs. And the final file should have exact number of spaces as the original file....only thing changing should be the date format. How can I do this? I wrote a script but it will lose the original spaces and positioning will be messed up. file.each_line do |line| dob = line.split(" ") puts dob[3] #got the date. change its format 5.times { puts "**" } end Can anyone suggest a better strategy so that positioning in the original file remains the same?
