  • How to make a Shell Script create a copy and terminate itself?

    - by ricedragon
    So far I used trap " call function" 2 fucntion { ./test.sh exit } but it never reaches the exit line and a whole bunch of process piles up any one got any idea? I tried & (bg) but i need to be able to keep doing it , the bg only allows me to do it once The point of it is when i type ctrl C it should terminate the original test.sh but it should also call itself before terminating hence create a new process.

  • how to access jquery internal data?

    - by Unknown
    As you may or may not be aware as of jQuery 1.7 the whole event system was rewritten from the ground up. The codebase is much faster and with the new .on() method there is a lot of uniformity to wiring up event handlers. One used to be able to access the internal events data and investiate what events are registered on any given element, but recently this internal information has been hidden based on the following scenario... It seems that the "private" data is ALWAYS stored on the .data(jQuery.expando) - For "objects" where the deletion of the object should also delete its caches this makes some sense. In the realm of nodes however, I think we should store these "private" members in a separate (private) cache so that they don't pollute the object returned by $.fn.data()" Although I agree with the above change to hide the internal data, I have found having access to this information can be helpful for debugging and unit testing. What was the new way of getting the internal jquery event object in jQuery 1.7?

  • jquery $.ajax not working in firefox against rails (406 response) (works in chrome & IE)

    - by phil swenson
    I have a rails backend and am testing the following jquery code against it: var content = $("#notification_content").val(); var data = new Object(); data.content = content; $.ajax({ url: "/notifications/detect_type.json", type:"POST", data: data, success: function(result ){updateTypeDropDown(result)}}); This code works fine in Chrome and IE. However in Firefox (using Firebug), I see this: http://localhost:3000/notifications/detect_type.json 406 Not Acceptable here is a chrome request in the log: Processing NotificationsController#detect_type (for 127.0.0.1 at 2010-12-21 17:05:59) [POST] Parameters: {"action"="detect_type", "content"="226 south emerson denver co 80209", "controller"="notifications"} User Columns (2.0ms) SHOW FIELDS FROM users User Load (37.4ms) SELECT * FROM users WHERE (users.id = '1') LIMIT 1 Completed in 58ms (View: 1, DB: 40) | 406 Not Acceptable [http://localhost/notifications/detect_type.json] here is a firefox request in the log: Processing NotificationsController#detect_type (for 127.0.0.1 at 2010-12-21 17:06:41) [POST] Parameters: {"action"="detect_type", "content"="226 south emerson 80209", "controller"="notifications"} User Columns (2.1ms) SHOW FIELDS FROM users User Load (30.4ms) SELECT * FROM users WHERE (users.id = '1') LIMIT 1 Completed in 100ms (View: 1, DB: 33) | 200 OK [http://localhost/notifications/detect_type.json] I'm stumped.

  • Changing filesystem types "safely"

    - by warren
    Back in Windows 95 OSR2 (I believe), there was a conversion tool that would take your extant FAT16 partition and change it to FAT32 non-destructively (most of the time). Are there any tools like that now for going from one file system type to another in situ without destroying the data? For example, from etx3 to ext4? Or NTFS to XFS?

  • how to prevent database to add slash to quotes

    - by black sensei
    i know this sounds really common and so trivial but , am having a challenge here. I have a web site with Zend/Doctrine and i use ckeditor for the backend management. after uploading the site i've realized that during edit testing the look and feel of the site is messed up. with the help of firebug, i've seen that there are slashes all over the html. after inline edition, the look and feel came back to normal. There are so many files , i can't think of doing other decoding before outputting data from mysql. What options do i have to solve this problem. the site is up already and i feel a bit unconfortable about this. Can anyone give a hint? thanks

  • TCP 30 small packets per second polutes connection with server

    - by Denis Ermolin
    I'm testing connection with flash client and cloud server(boost::asio for software) over TCP connection. My connection with server already is really poor - 120 ms ping in average. I found when i start to send packets with 2 bytes size (without tcp header) with speed 30 packets/s ping grow to 170-200 average. I think that it's really bad and my bad connection and bad cloud provider is reason for this high ping without any load. What do you think? (I tested my software and can compute about 50k packets/s so software is not a problem).

  • vBulletin 5 + lighttpd url rewriting

    - by Boots
    I'm trying to get vBulletin 5 up and running under lighttpd but I'm having some problems with url rewriting. Here is the apache .htaccess provided by vBulletin. <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?routestring=$1 [L,QSA] #needed because admincp is an actual directory. RewriteRule ^(admincp/)$ index.php?routestring=$1 [L,QSA] </IfModule> If this helps, this is the IIS config provided by vBulletin <?xml version="1.0" encoding="UTF-8"?> <!-- This file is to support redirection in IIS. It is harmless if you are running under Apache --> <configuration> <system.webServer> <rewrite> <rules> <rule name="Main Redirect" stopProcessing="true"> <match url="^(.*)$" ignoreCase="false" /> <conditions logicalGrouping="MatchAll"> <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" /> </conditions> <action type="Rewrite" url="index.php/{R:1}" /> </rule> <rule name="Admincp" stopProcessing="true"> <match url="^(admincp/)$" ignoreCase="false" /> <action type="Rewrite" url="index.php/{R:1}" /> </rule> </rules> </rewrite> </system.webServer> </configuration> Anyone have any suggestions as to the lighttpd url.rewrite equivalent? All my experiments have failed thus far. I'm running lighttpd-1.4.31-1 I tried this but it didn't work. I think it has something to do with me not properly emulating [QS] in the .htaccess url.rewrite-once = ("^(.*)$" => "index.php?routestring=$1", "^(admincp/)$)" => "index.php?routestring=$1") This has gotten me closer but not fully functional yet. url.rewrite-if-not-file = ("^(.*)$" => "index.php?routestring=$1", "^(admincp/)$)" => "index.php?routestring=$1")

  • How to assess the risk of a java version upgrade?

    - by Roy Tang
    I'm being asked to assess whether we can safely upgrade the java version on one of our production-deployed webapps. The codebase is fairly large and we want to avoid having to regression test everything (no automated tests sadly), but we've already encountered at least one problem during some manual testing (XmlStringReader.getLocalName now throws an IllegalStateExeption when it just used to return null) and higher-ups are pretty nervous about the upgrade. The current suggested approach is to do a source compare of the JDK sources for each version and assess those changes to see which ones might have impact, but it seems there's a lot of changes to go through (and as mentioned the codebase is kinda large). Is it safe and easier to just review the java version changes for each version? Or is there an easier way to conduct this assessment? Edit: I forgot to mention the version upgrade being considered is a minor version upgrade, i.e. 1.6.10 to 1.6.33

  • Search for rot13 text

    - by Andrew Grimm
    Is it possible to do web searches for ROT13 text? I guess you could type in the literal ROT13'd text you're after, but that'd only cover exact matches. Background: Became curious once I did a ROT13 tweet about a tv program being a mockumentary.

  • Class Library Project VS App_Code - Pros / Cons?

    - by rockinthesixstring
    I currently use the App_Code folder for all of my classes, and for me (for now) it seems to be working just fine. I have however been considering making the switch over to a Class Library Project inside my Solution instead of the App_Code folder. Can anyone tell me the pros and cons of doing this? One thought I had was with regards to testing my web app. If I use a Class Library, do I have to compile it every time I want to tweak/test? Obviously in the App_Code folder I don't have to since all of the Classes compile at runtime.

  • Identify Encoded Strings

    - by Steven
    Does anyone know of a utility (any OS or online) that, with a string input, identifies the encoding type (checksum, base64, etc) and if possible (and appropriate) decodes the string?

  • How often should we write unit tests?

    - by Midnight Blue
    Hi, I am recently introduced to the test-driven approach to development by my mentor at work, and he encourages me to write an unit-test whenenver "it makes sense." I understand some benefits of having a throughout unit-test suite for both regression testing and refractoring, but I do wonder how often and how throughout we should write unit-test. My mentor/development lead asks me to write a new unit test-case for a newly written control flow in a method that is already being tested by the exsisting test class, and I think it is an overkill. How often do you write your unit tests, and how detailed do you think your unit tests should be? Thanks!

  • PowerISO for Mac can't convert .img

    - by None
    I have a bootable .img file that I want to convert to a bootable .iso file. I downloaded poweriso for Mac and used this command: poweriso convert MyOS.img -o MyOS.iso -ot iso which returned this output: PowerISO Copyright(C) 2004-2008 PowerISO Computing, Inc Type poweriso -? for help MyOS.img: The file format is invalid or unsupported. I thought PowerISO could convert .img to .iso. Was I incorrect, or did I use the wrong commands or something like that?

  • How can I create an ODBC connection to SAS?

    - by Chris B.
    I'm writing a program that needs to access SAS data. I've downloaded the ODBC drivers for SAS and installed them, but I need to be able to create ODBC connections on the fly, programmatically. The following code (in Python) seems like it should work: import ctypes ODBC_ADD_DSN = 1 def add_dsn(name, driver, **kw): nul, attrib = chr(0), [] kw['DSN'] = name for attr, val in kw.iteritems(): attrib.append('%s=%s' % (attr, val)) return ctypes.windll.ODBCCP32.SQLConfigDataSource(0, ODBC_ADD_DSN, driver, nul.join(attrib)) == 1 print add_dsn('SAS Test', 'SAS', description = 'Testing SAS') But it pops up the SAS ODBC configuration dialog, sets the datasource name, and waits for the user to enter the information and dismiss the dialog. How can I avoid that?

  • Can not login Magento admin page after move to my localhost

    - by Xinrui Ma
    I just move my Magento store to my localhost environment for testing use, I also using Git to maintain code, but after I move all the files to my local environment, I can't login my admin page, but I can still see my frontend pages, and the git, the database, seems works well. When I type a wrong admin/password to my admin page, it still gives me "Invalid password". But when I enter the right one, it just refresh the page and stay at the login page, nothing happens. Does anyone has met this problem before? Has any ideas? Thanks in advance!

  • Call javascript function from Java (Groovy) class

    - by ashkanr
    Hi, I have a javascript function (very big one!) that I need its functionality in a Java (Groovy) class. It is a simple calendar converter. I can rewrite it in groovy but just want to know if it is possible to call javascript function from a java (groovy) method? I guess functional testing libraries like selenium and Canoo should have something like this, am I right? PS: I don't want to wake up a real-world browser in order to use its JS runtime env. Thanks,

  • Cascading Dropdown Listboxes with Selenium

    - by Jon
    I am having great difficultly testing cascading dropdown boxes with Selenium. I would like to know what the standard approach is for this. I'm a bit unclear as to which commands to use i.e. ClickAndWait, WaitForTextPresent etc. It seems a little bit of a hack to try and get this to work. Has anyone got selenium to correctly test this out? An example scenario would be to have 3 listboxes which have Car Make, Model and Colour. Each one is populated in turn by the other. Selenium needs to somehow wait for the next listbox to populate before preceeding with the test.

  • facebook app development

    - by musoNic80
    I have always developed my projects using MAMP locally and once done simply uploaded everything to a live server. However, I'm wanting to integrate some FB functionality in my current project and I believe I'm correct in saying that it is not possible to fully test FB integration locally. My problem is I don't want to release the project I'm working on until it's finished (or at least nearly finished!) by placing it on a live server. I don't even want people to see a login screen or anything. Is there a way I can upload everything to my domain for testing purposes but prevent anyone apart from me from accessing the site?

  • Help with Linq and Generics

    - by Jonathan
    Hi to all. I'm triying to make a function that add a 'where' clause to a query based in a property and a value. This is a very simplefied version of my function. Private Function simplified(ByVal query As IQueryable(Of T), ByVal PValue As Long, ByVal p As PropertyInfo) As ObjectQuery(Of T) query = query.Where(Function(c) DirectCast(p.GetValue(c, Nothing), Long) = PValue) Dim t = query.ToList 'this line is only for testing, and here is the error raise Return query End Function The error message is: LINQ to Entities does not recognize the method 'System.Object CompareObjectEqual(System.Object, System.Object, Boolean)' method, and this method cannot be translated into a store expression. Looks like a can't use GetValue inside a linq query. Can I achieve this in other way? Post your answer in C#/VB. Chose the one that make you feel more confortable. Thanks

  • Can I assume Flash and PHP will generate the same floating point numbers?

    - by Fragsworth
    In a multiplayer game I'm developing, we have a few values that are floating point numbers. The back-end (in PHP) and the front-end (in Flash) occasionally perform the same calculations on these numbers, to minimize communication. I am currently making sure that both sides are using 64-bit doubles, but am I safe to assume that all calculations will be the same? For instance, what about string to float conversion - should I worry about Flash having a potentially different implementation as PHP? (If this happens, our game will go out of sync - the client will think it is in one state while the server is in another) With some testing, it appears to be the same, but I'm just not sure. Can someone clarify this for me?

  • posting to aweber with jQuery

    - by wcpro
    Im trying to post to aweber using just jquery. I have a method call like this $(function () { $('#submit').click(function () { $.post('http://www.aweber.com/scripts/addlead.pl', { meta_web_form_id: '12345', meta_split_id: '', listname: 'some_list', redirect: '', meta_redirect_onlist: '', meta_adtracking: 'my_Web_Form', meta_message: '1', meta_required: 'name,email', meta_forward_vars: '', meta_tooltip: '', email : '[email protected]', name : 'tester testing' }, function (data) { alert('data load: ' + data); }); }); }); it is supposed to take the result of the post and alert it in a box. when i try to do it manually with forms it works but redirects me to a 'form-sorry.htm' page, which is fine, just wondering if there was a way to display the end result of the post. Im guessing hte addlead.pl is just a posting page with no response.

  • Creating an n tiered application

    - by aaron
    I am researching architecture for a project that will be started next year. It is mainly a c# web app, but there will be a service layer so that it can talk to our facebook/iphone app. There are a few long running processes, which means that I will be creating a windows process that can handle those. I’m thinking of putting the entire app in the windows service instead of just the long running processes. Asp - wcf - bll Vs Asp - bll I know this will be more scalable. But it is probably overkill as everything will be running on the same box, even the database. This could change down the road if the server can’t handle the traffic like marketing says it will. I don’t have access to production hardware, just my crappy testing box and my local machine. Has anyone decided to go down this route? But mostly, what is the best way to test both methods to get some metrics?
