  • CVS in cmd/gui works only the third time I run a command.

    - by Somebody still uses you MS-DOS
    I'm using CVS in the command line. I'm in my repository folder. When I call a CVS command, I get... cvs [log aborted]: unrecognized auth response from localhost: -f [pserver aborted]: /opt/cvs/XXXXXX: no such repository ...2 times. The third time I run the command, it works with no problems. I tried to use a GUI client (CrossVC) and the same problem occurs. I tried inside gVim and Vim using VCSCommand and I'm having the same issues as well. I've tested with different times between each command, but I still have the same problems. I'm using a CVS configuration with stunnel. Why am I having problem with this setup? Why every time just the third time that I try to run the command that actually works?

  • mySQL Trigger works after console insert, but not after script insert.

    - by Marcos
    Hello, I have a strange wird problem with a trigger: I set up a trigger for update other tables after an insert in a table. If i make an insert from mysql console, all works fine, but if i do inserts from external python script, trigger does nothing, as you can see bellow. When i insert from console, works fine, but insert THE SAME DATA from python script, doesn't works, i try changing the Definer to 'user'@'%' and 'root'@'%' but stills doing nothing. Any idea of what van be wrong?

  • how could it works if function is called before it is defined in python?

    - by user2131316
    I was wondering what does if __name__ == "__main__": really do in python, I have the following code in python3: def main(): test(); def test(): print("hello world " + __name__); if __name__ == "__main__": main(); we know that we have to declare a function before we use it, so function call inside of if part works fine, the main() is defined before it is called inside of if statement, but what about the test() function, it is defined after it is called and there is no errors: def main(): test(); def test(): print("hello world " + __name__); so how could it works if the test() function is defined after it is called?

  • mysql_connect() doesn't work when run by apache; works from command line.

    - by Skeeter
    Hi, I have a strange issue. I'm trying to write a simple php webpage on my server, but mysql_connect() doesn't connect to any server, either local or otherwise. Here's where it gets strange. If I take the same php script and run it from the commandline, the script works. phpinfo() indicates that both the file (being run by apache) and the commandline (run as root) are calling the same version of php, mysql is loaded, and the php.ini is the same. Furthermore, I'm running a MediaWiki installation on this same server, and it's using the mysqld installed locally and works just fine, so I'm completely at a loss as to why the code isn't working. The error I receive on runtime: Can't connect to MySQL server on 'xxx.xxx.xxx.xxx' (13) (The IP is x'd out for the privacy of the owner of the server I'm connecting to)

  • Is using a DataSet's column Expression works in background same as manual calculation?

    - by Harikrishna
    I have one datatable which is not bindided and records are coming from the file by parsing it in the datatable dynamically every time. Now there is three columns in the datatable Marks1,Marks2 and FinalMarks. And their types is decimal. Now for making addition of columns Marks1 and Marks2 's records and store it into FinalMarks column,For that what I do is : datatableResult.Columns["FinalMarks"].Expression="Marks1+Marks2"; It's works properly. It can be done in other way also is foreach (DataRow r in datatableResult.Rows) { r["FinalMarks"]=Convert.ToDecimal(r["Marks1"])+Convert.ToDecimal(r["Marks2"]); } Is first approach same as second approach in background means is both approach same or what? EDIT: I want to know that first approach works in background as second approach.

  • Why $(":select").focus does not work while $(":input").focus works?

    - by user605660
    Hi. I have a JQuery code which does something when input or select elements get focus. Although my code for input element works, select element does not work. Here is what I do. <body> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript"> $(document).ready(function(){ $(":input").focus(function () { //this works //do something }); $(":select").focus(function () { //this doesn't //do something }); }); </script> </body> I tried some variation on select, such as using $("select") instead of $(":select"), but did not work either. I am a beginner for JQuery. I appreciate if you could tell me how I can make it work. Thanks a lot!

  • Does anyone really understand how HFSC scheduling in Linux/BSD works?

    - by Mecki
    I read the original SIGCOMM '97 PostScript paper about HFSC, it is very technically, but I understand the basic concept. Instead of giving a linear service curve (as with pretty much every other scheduling algorithm), you can specify a convex or concave service curve and thus it is possible to decouple bandwidth and delay. However, even though this paper mentions to kind of scheduling algorithms being used (real-time and link-share), it always only mentions ONE curve per scheduling class (the decoupling is done by specifying this curve, only one curve is needed for that). Now HFSC has been implemented for BSD (OpenBSD, FreeBSD, etc.) using the ALTQ scheduling framework and it has been implemented Linux using the TC scheduling framework (part of iproute2). Both implementations added two additional service curves, that were NOT in the original paper! A real-time service curve and an upper-limit service curve. Again, please note that the original paper mentions two scheduling algorithms (real-time and link-share), but in that paper both work with one single service curve. There never have been two independent service curves for either one as you currently find in BSD and Linux. Even worse, some version of ALTQ seems to add an additional queue priority to HSFC (there is no such thing as priority in the original paper either). I found several BSD HowTo's mentioning this priority setting (even though the man page of the latest ALTQ release knows no such parameter for HSFC, so officially it does not even exist). This all makes the HFSC scheduling even more complex than the algorithm described in the original paper and there are tons of tutorials on the Internet that often contradict each other, one claiming the opposite of the other one. This is probably the main reason why nobody really seems to understand how HFSC scheduling really works. Before I can ask my questions, we need a sample setup of some kind. I'll use a very simple one as seen in the image below: Here are some questions I cannot answer because the tutorials contradict each other: What for do I need a real-time curve at all? Assuming A1, A2, B1, B2 are all 128 kbit/s link-share (no real-time curve for either one), then each of those will get 128 kbit/s if the root has 512 kbit/s to distribute (and A and B are both 256 kbit/s of course), right? Why would I additionally give A1 and B1 a real-time curve with 128 kbit/s? What would this be good for? To give those two a higher priority? According to original paper I can give them a higher priority by using a curve, that's what HFSC is all about after all. By giving both classes a curve of [256kbit/s 20ms 128kbit/s] both have twice the priority than A2 and B2 automatically (still only getting 128 kbit/s on average) Does the real-time bandwidth count towards the link-share bandwidth? E.g. if A1 and B1 both only have 64kbit/s real-time and 64kbit/s link-share bandwidth, does that mean once they are served 64kbit/s via real-time, their link-share requirement is satisfied as well (they might get excess bandwidth, but lets ignore that for a second) or does that mean they get another 64 kbit/s via link-share? So does each class has a bandwidth "requirement" of real-time plus link-share? Or does a class only have a higher requirement than the real-time curve if the link-share curve is higher than the real-time curve (current link-share requirement equals specified link-share requirement minus real-time bandwidth already provided to this class)? Is upper limit curve applied to real-time as well, only to link-share, or maybe to both? Some tutorials say one way, some say the other way. Some even claim upper-limit is the maximum for real-time bandwidth + link-share bandwidth? What is the truth? Assuming A2 and B2 are both 128 kbit/s, does it make any difference if A1 and B1 are 128 kbit/s link-share only, or 64 kbit/s real-time and 128 kbit/s link-share, and if so, what difference? If I use the seperate real-time curve to increase priorities of classes, why would I need "curves" at all? Why is not real-time a flat value and link-share also a flat value? Why are both curves? The need for curves is clear in the original paper, because there is only one attribute of that kind per class. But now, having three attributes (real-time, link-share, and upper-limit) what for do I still need curves on each one? Why would I want the curves shape (not average bandwidth, but their slopes) to be different for real-time and link-share traffic? According to the little documentation available, real-time curve values are totally ignored for inner classes (class A and B), they are only applied to leaf classes (A1, A2, B1, B2). If that is true, why does the ALTQ HFSC sample configuration (search for 3.3 Sample configuration) set real-time curves on inner classes and claims that those set the guaranteed rate of those inner classes? Isn't that completely pointless? (note: pshare sets the link-share curve in ALTQ and grate the real-time curve; you can see this in the paragraph above the sample configuration). Some tutorials say the sum of all real-time curves may not be higher than 80% of the line speed, others say it must not be higher than 70% of the line speed. Which one is right or are they maybe both wrong? One tutorial said you shall forget all the theory. No matter how things really work (schedulers and bandwidth distribution), imagine the three curves according to the following "simplified mind model": real-time is the guaranteed bandwidth that this class will always get. link-share is the bandwidth that this class wants to become fully satisfied, but satisfaction cannot be guaranteed. In case there is excess bandwidth, the class might even get offered more bandwidth than necessary to become satisfied, but it may never use more than upper-limit says. For all this to work, the sum of all real-time bandwidths may not be above xx% of the line speed (see question above, the percentage varies). Question: Is this more or less accurate or a total misunderstanding of HSFC? And if assumption above is really accurate, where is prioritization in that model? E.g. every class might have a real-time bandwidth (guaranteed), a link-share bandwidth (not guaranteed) and an maybe an upper-limit, but still some classes have higher priority needs than other classes. In that case I must still prioritize somehow, even among real-time traffic of those classes. Would I prioritize by the slope of the curves? And if so, which curve? The real-time curve? The link-share curve? The upper-limit curve? All of them? Would I give all of them the same slope or each a different one and how to find out the right slope? I still haven't lost hope that there exists at least a hand full of people in this world that really understood HFSC and are able to answer all these questions accurately. And doing so without contradicting each other in the answers would be really nice ;-)

  • jquery $.getJSON only works once in internet explorer Help Please!!!

    - by JasperS
    I have a php function which inserts a searchbar into each page on a website. The site checks to see if the user has javascript enabled and if they do it inserts some jquery ajax stuff to link select boxes (instead of using it's fallback onchange="form.submit()"). $.getJSON works perfectly for me in other browsers except in IE, if I do a full page refresh (ctrl+F5) in IE my ajax works flawlessly until I navigate to a new page (or the same page with $PHP_SELF) either by submiting the form or clicking a link the jquery onchange function fires but then jquery throws an error: Webpage error details Message: Object doesn't support this property or method Line: 123 Char: 183 Code: 0 URI: http://~#UNABLE~TO~DISCLOSE#~/jquery-1.4.2.min.js It seems like jquery function $.getJSON() is gone??? This seems to be some kind of caching issue as it happens on the second page load but I think i've go all the caching prevention in place anyways, here's a snipet of the code that ads the jquery functions: if (isset($_SESSION['NO_SCRIPT']) == true && $_SESSION['NO_SCRIPT'] == false) { $html .= '<script type="text/javascript" charset="utf-8">'; $html .= '$.ajaxSetup({ cache: false });'; $html .= '$.ajaxSetup({"error":function(XMLHttpRequest,textStatus, errorThrown) { alert(textStatus); alert(errorThrown); alert(XMLHttpRequest.responseText); }});'; $html .= '</script>'; $html .= '<script type="text/javascript" charset="utf-8">'; $html .= '$(function(){ $("select#searchtype").change(function() { '; $html .= 'alert("change fired!"); '; $html .= '$.getJSON("ajaxgetcategories.php", {id: $(this).val()}, function(j) { '; $html .= 'alert("ajax returned!"); '; $html .= 'var options = \'\'; '; $html .= 'options += \'<option value="0" >--\' + j[0].all + \'--</option>\'; '; $html .= 'for (var i = 0; i < j.length; i++) { options += \'<option value="\' + j[i].id + \'">\' + j[i].name + \'</option>\'; } '; $html .= '$("select#searchcategory").html(options); }) }) }) '; $html .= '</script> '; $html .= '<script type="text/javascript" charset="utf-8"> '; $html .= '$(function(){ $("select#searchregion").change(function() { '; $html .= 'alert("change fired!"); '; $html .= '$.getJSON("ajaxgetcountries.php", {id: $(this).val()}, function(j) { '; $html .= 'alert("ajax returned!"); '; $html .= 'var options = \'\'; '; $html .= 'options += \'<option value="0" >--\' + j[0].all + \'--</option>\'; '; $html .= 'for (var i = 0; i < j.length; i++) { options += \'<option value="\' + j[i].id + \'">\' + j[i].name + \'</option>\'; } '; $html .= '$("select#searchcountry").html(options); }) }) }) '; $html .= '</script> '; }; return $html; remember, this is part of a php funtion that inserts a script into the html and sorry if it looks a bit messy, I'm new to PHP and Javascript and I'm a bit untidy too :) Please also remember that this works perfectly in IE on the first visit but after any navigation I get the error. Thanks guys

  • Relative Uri works for BitmapImage, but not for MediaPlayer?

    - by Thomas Stock
    This will be simple for you guys: var uri = new Uri("pack://application:,,,/LiftExperiment;component/pics/outside/elevator.jpg"); imageBitmap = new BitmapImage(); imageBitmap.BeginInit(); imageBitmap.UriSource = uri; imageBitmap.EndInit(); image.Source = imageBitmap; = Works perfectly on a .jpg with Build Action: Content Copy to Output Directory: Copy always MediaPlayer mp = new MediaPlayer(); var uri = new Uri("pack://application:,,,/LiftExperiment;component/sounds/DialingTone.wav"); mp.Open(uri); mp.Play(); = Does not work on a .wav with the same build action and copy to output. I see the file in my /debug/ folder.. MediaPlayer mp = new MediaPlayer(); var uri = new Uri(@"E:\projects\LiftExp\_solution\LiftExperiment\bin\Debug\sounds\DialingTone.wav"); mp.Open(uri); mp.Play(); = Works perfectly.. So, how do I get the sound to work with a relative path? Why is it not working this way? Let me know if you want more code or screenshots. Thanks.

  • object_getInstanceVariable works for float, int, bool, but not for double?

    - by Russel West
    I've got object_getInstanceVariable to work as here however it seems to only work for floats, bools and ints not doubles. I do suspect I'm doing something wrong but I've been going in circles with this. float myFloatValue; float someFloat = 2.123f; object_getInstanceVariable(self, "someFloat", (void*)&myFloatValue); works, and myFloatValue = 2.123 but when I try double myDoubleValue; double someDouble = 2.123f; object_getInstanceVariable(self, "someDouble", (void*)&myDoubleValue); i get myDoubleValue = 0. If I try to set myDoubleValue before the function eg. double myDoubleValue = 1.2f, the value is unchanged when I read it after the object_getInstanceVariable call. setting myIntValue to some other value before the getinstancevar function above returns 2 as it should, ie. it has been changed. then I tried Ivar tmpIvar = object_getInstanceVariable(self, "someDouble", (void*)&myDoubleValue); if i do ivar_getName(tmpIvar) i get "someDouble", but myDoubuleValue = 0 still! then i try ivar_getTypeEncoding(tmpIvar) and i get "d" as it should be. So to summarize, if typeEncoding = float, it works, if it is a double, the result is not set but it correctly reads the variable and the return value (Ivar) is also correct. I must be doing something basic wrong that I cant see so I'd appreciate if someone could point it out.

  • How to make this into a self contained jQuery plugin? Works inline.

    - by Jannis
    Hi, I have been trying to make this to be a little jQuery plugin that I can reuse in the future without having to write the following into my actions.js file in full. This works when loaded in the same file where I set the height using my variable tallest. var tallest = null; $('.slideshow img').each(function(index) { if ($(this).height() >= tallest ) { tallest = $(this).height(); } }); $('.slideshow').height(tallest); This works and will cycle through all the items, then set the value of tallest to the greatest height found. The following however does not work: This would be the plugin, loaded from its own file (before the actions.js file that contains the parts using this): (function($){ $.fn.extend({ tallest: function() { var tallest = null; return this.each(function() { if ($(this).height() >= tallest ) { tallest = $(this).height(); } }); } }); })(jQuery); Once loaded I am trying to use it as follows: $('.slideshow img').tallest(); $('.slideshow').height(tallest); However the above 2 lines return an error of 'tallest is undefined'. How can I make this work? Any ideas would be appreciated. Thinking about this even more the perfect usage of this would be as follows: $('.container').height(tallest('.container item')); But I wouldn't even know where to begin to get this to work in the manner that you pass the object to be measured into the function by adding it into the brackets of the function name.. Thanks for reading, Jannis

  • CreateThread() fails on 64 bit Windows, works on 32 bit Windows. Why?

    - by Stephen Kellett
    Operating System: Windows XP 64 bit, SP2. I have an unusual problem. I am porting some code from 32 bit to 64 bit. The 32 bit code works just fine. But when I call CreateThread() for the 64 bit version the call fails. I have three places where this fails. 2 call CreateThread(). 1 calls beginthreadex() which calls CreateThread(). All three calls fail with error code 0x3E6, "Invalid access to memory location". The problem is all the input parameters are correct. HANDLE h; DWORD threadID; h = CreateThread(0, // default security 0, // default stack size myThreadFunc, // valid function to call myParam, // my param 0, // no flags, start thread immediately &threadID); All three calls to CreateThread() are made from a DLL I've injected into the target program at the start of the program execution (this is before the program has got to the start of main()/WinMain()). If I call CreateThread() from the target program (same params) via say a menu, it works. Same parameters etc. Bizarre. If I pass NULL instead of &threadID, it still fails. If I pass NULL as myParam, it still fails. I'm not calling CreateThread from inside DllMain(), so that isn't the problem. I'm confused and searching on Google etc hasn't shown any relevant answers. If anyone has seen this before or has any ideas, please let me know. Thanks for reading.

For reference, here is the page+source (all my code is currently in index.html so you can just "View Source" to see it all): http://rpj.me/doughapp.com/wd/ Essentially, I'm trying to save pertinent JSON objects retrieved from Google Local into DOM objects using the data() method (in this example, obj is the Google Local object): $('#locPane').data('selected', obj); then later (in a different "pane"), retrieving that object to be used: $('#locPane').bind('pageAnimationEnd', function(e, inf) { var selobj = $(this).data('selected'); // use 'selobj' here ... } In Chromium and Safari on the desktop OS (Snow Leopard in my case), this works perfectly (try it out). However, the same code returns undefined for the call to $(this).data('selected') in the second snippet above. I've also tried $('#' + e.target.id).data('selected') and even the naive $('#locPane').data('selected'). All variants return undefined in the iPhone OS version of WebKit, but not on the desktop. Interestingly, the running this on Mobile Safari in the iPhone Simulator fails as well. If you look at the full source, you'll see that I even try to save this object into my global jQTouch object (named jqt in my code). This, too, fails on the mobile platform. Has anyone else ever ran into this? I'll admit to not being a web/javascript programmer by trade, so if I'm making an idiot's error please call me out on it. Thank you in advance for the help! -RPJ Update: I didn't make it clear in the original post, but I'm open to any workaround if it works consistently. Since I'm having trouble storing these objects in general, anything that allows me to keep them around is good enough for now. Thanks!

  • Works for Short Input, Fails for Long Input. How to Solve?

    - by r0ach
    I've this program which finds substring in a string. It works for small inputs. But fails for long inputs. Here's the program: //Find Substring in given String #include <stdio.h> #include <string.h> main() { //Variable Initialization int i=0,j=0,k=0; char sentence[50],temp[50],search[50]; //Gets Strings printf("Enter Sentence: "); fgets(sentence,50,stdin); printf("Enter Search: "); fgets(search,50,stdin); //Actual Work Loop while(sentence[i]!='\0') { k=i;j=0; while(sentence[k]==search[j]) { temp[j]=sentence[k]; j++; k++; } if(strcmp(temp,search)==0) break; i++; } //Output Printing printf("Found string at: %d \n",k-strlen(search)); } Works for: Enter Sentence: good evening Enter Search: evening Found string at 6 Fails for: Enter Sentence: dear god please make this work Enter Search: make Found string at 25 Which is totally wrong. Can any expert find me a solution? P.S: This is kinda like reinventing the wheel since strstr() has this functionality. But I'm trying for a non-library way of doing it.

  • Rails 2.3.4 and jquery form plugin works on development, not in production?

    - by hemajang
    Hello, i'm trying to build a contact form in Rails 2.3.4. I'm using the jQuery Form plugin along with this (http://bassistance.de/jquery-plugins/jquery-plugin-validation/) for validations. Everything works in my development environment (mac os x snow leopard), the loading gif appears and on my log the email gets sent and the "request completed" notice shows. But on my production machine the loading gif just keeps going and the form doesn't get sent. I've waited as long as I could, nothing. Here is my code: /public/javascripts/application.js // client-side validation and ajax submit contact form $('#contactForm').validate( { rules: { 'email[name]': { required: true }, 'email[address]': { required: true, email: true }, 'email[subject]': { required: true }, 'email[body]': { required: true } }, messages: { 'email[name]': "Please enter your name.", 'email[address]': "Please enter a valid email address.", 'email[subject]': "Please enter a subject.", 'email[body]': "Please enter a message." }, submitHandler: function(form) { $(form).ajaxSubmit({ dataType: 'script', beforeSend: function() { $(".loadMsg").show(); } }); return false; } }); I'm using the submitHandler to send the actual ajaxSubmit. I added the "dataType: "script" and the "beforeSubmit" for the loading graphic. def send_mail if request.post? respond_to do |wants| ContactMailer.deliver_contact_request(params[:email]) flash[:notice] = "Email was successfully sent." wants.js end end end Everything works fine on development, but not in production. What am I missing or did wrong?

  • How to include an apache library with my opensource code?

    - by OscarRyz
    I have this opensource code with MIT license that uses an Apache 2.0 licensed library. I want to include this in my project, so it can be built right away. In the point 4 of that license explains how to redistribute it: excerpt: 4 . Redistribution. You may reproduce and distribute copies of the Work or Derivative Works thereof in any medium, with or without modifications, and in Source or Object form, provided that You meet the following conditions: You must give any other recipients of the Work or Derivative Works a copy of this License; and You must cause any modified files to carry prominent notices stating that You changed the files; and You must retain, in the Source form of any Derivative Works that You distribute, all copyright, patent, trademark, and attribution notices from the Source form of the Work, excluding those notices that do not pertain to any part of the Derivative Works; and If the Work includes a "NOTICE" text file as part of its distribution, then any Derivative Works that You distribute must include a readable copy of the attribution notices contained within such NOTICE file, excluding those notices that do not pertain to any part of the Derivative Works, in at least one of the following places: within a NOTICE text file distributed as part of the Derivative Works; within the Source form or documentation, if provided along with the Derivative Works; or, within a display generated by the Derivative Works, if and wherever such third-party notices normally appear.

I'm not creating a derivative work ( I plan to provide it as it is ). I don't have a NOTICE file, just my my own LICENSE.txt file. Question: Where should I put something along the lines: "This project uses Xyz library distributed under Apache2.0 ..."? What's recommented? Should I provide the apache license file too? Or would be enough if I just say "Find the license online here...http://www.apache.org/licenses/LICENSE-2.0.html" I hope someone who has done this in the past may shed some light on the matter.

  • Vim syntax highlighting not working (but works in gvim?)

    - by victor
    I've followed all instructions given on this site with an empty .vim folder, but for some reason, python highlighting is not working on my system. It only highlights the comments and a few variables - nothing like the picture. http://concisionandconcinnity.blogspot.com/2009/07/vim-part-i-improved-python-syntax.html Is there some other setting I am forgetting? I'm also using ubuntu 10.04 if that matters. A weird other note - it works in gvim, but not vim?
