  • What set of tools make up "the rails way" of testing javascript in the browser?

    - by Jordan Feldstein
    What's the concensus for doing in-browser (either headless or remote-controlled) testing of javascript? Unit testing my JS is nice, but can't protect against irresponsible changes to the DOM. Unit testing of the JS and functional testing of the views to make sure they both provide and utilize the same, correct DOM, might work, but then the link between JS and DOM is being covered in two places which seems brittle or cumbersome. Is there an acknowledged "Rails Way" to implement full-stack tests, where I can run my javascript against the DOM rendered by the rest of the app, and check the results? (Something like what PHPUnit and Selenium give us, but inside the rails framework?)

  • Should I leave href empty when implementing click events via jQuery?

    - by dreza
    Is it preferable to have # in a link's href attribute when I am implementing the click event via jQuery, or is it ok to leave href empty? i.e. <a id="myLink" href="#" /> vs <a id="myLink" href="" /> When I'm doing $("#myLink").on('click', function() { // do ajaxy stuff }); Although I understand the click event could be on a span or other such element I'm interested in this case for particular best practices when using an a tag.

  • Examples of Android Joystick Controls? [on hold]

    - by KRB
    I can't seem to find any well executed code examples for Android joystick controls. Whatever it may be, algorithms, pseudo code, actual code examples, strategies, or anything to assist with the design and implementation of Android joystick controls; I can't seem to find anything decent on the net. What are some well executed examples? More specifically, Pseudo Code Current Examples Idea/Design Functionality Description Controller Hints Related Directly to Android Architecture What kind of classes will I have making this? Will there be only one? How would this be implemented to the game architecture? All things I am thinking about. Cheers! UPDATE I've found this on the subject Joystick Example1, though I am still looking for different examples/resources. Answered my own question with a link to the code of the above video. It's a fantastic start to Android Joystick Controls.

    - by Shota Bakuradze
    Now I know that this has been asked several times here but I couldn't find any decent solution to it. I am running Ubuntu 12.04 on my DELL N5110 and my touchpad is detected as a mouse, So I don't have the touchpad options availiable. Can't use multitouch and can't disable it either. I have tried the dkms driver from this link.

  • Cannot save all of the property settings for this Web Part.

    - by ybbest
    I would like to display all the items of custom content type of Animals in a SharePoint content query WebPart. After choosing the appropriate values in the web part editor and click on Save I got this error: Cannot save all of the property settings for this Web Part. There is a problem with one or more of the field values below. But when I examine all the values below , it does not flag any error information. I finally manage to locate the error flag after I expand the presentation section. I then delete the text in the Link textbox , now I can save the settings. However , I think the error message should have been more specific so that users can quickly locate the error. The worst part for this is that I did not even change anything in the presentation section, I merely configure the Source in the Query section. Well, I guess I am still new to SharePoint, I just have to get used to these generic error message ):

  • htaccess 301 redirect help needed

    - by John
    Due to some issues in my site many pages are visible as duplicate using : www.example.com/page.html?task=view but it's content is exactly same as www.example.com/page.html. One way is to use http 301 redirect from www.example.com/page.html?task=view to www.example.com/page.html when anybody fetches page with arguments. But links like www.example.com/page.html?task=view will remain visible to outside world. Another way is canonicalization which I don't want to use as it is difficult to insert the tag in Joomla CMS. I want to hide www.example.com/page.html?task=view from external world. Is it possible to change the url from www.example.com/page.html?task=view to www.example.com/page.html ? I mean if there is href link of www.example.com/page.html?task=view in my web page, it should be visible to external world as without any arguments. This is different from using 301 to convert externally accessed page : www.example.com/page.html?task=view to without using arguments in .htaccess.

  • I am new to game development, what do I need to know? [closed]

    - by farmdve
    I am unsure if this question is a duplicate, I hope it isn't. Are there any resources on the terminology when doing game development? Because, even if you tell me to learn some graphics API, how would I understand the things it does, if I am not well into the terminology(voxel,mesh,polygon,shading). What about the math that is involved in the game(geometry) or the concept of the gravity,collision detection in the game and their respective maths? I am very bad at math, never was good, because I have ADHD, but I won't give up just yet. I look at a game, and I see "textures", but how am I walking on them, how do they take substance so I don't fall off of them? And depth? This is what I need information about, not just a link to a library like SDL(which I have compiled under MinGW and MinGW-W64) and tell me to learn it and the cliché answer "start simple/small". I hope the question(s) are not too vague.

  • Missed question in technical phone interview and the follow up letter

    - by Jacob
    I may have just bombed a C++ technical phone interview. The interviewer asked mostly about data structures and I was able to go into detail about each of the data structures he asked about. Score one for me I'm thinking. Wrong. Then he asks to join me on a collaboration website where he can see what I am typing. This was the same process as interview #1 which went well, not perfect, but well. So the question was: How do you reverse a linked list? he gave a function prototype similar to Node *reverse(Node *head) I struggled with this for about 10-15 minutes until the hour was up. I was able to get the general idea across but was not able to reverse the link list. My question is that after remembering the answer post interview do I mention this in the thank you letter, if I even should write one?

  • Not assigning Bugs to a specific user

    - by user2977817
    My question: Is there a benefit to NOT assigning a Bug to a particular developer? Leaving it to the team as-a-whole? Our department has decided to be more Agile by not assigning Bugs/Defects to individuals. Using Team Foundation Server 2012, we'll place all Bugs in a development team's "Area" but leave the "Assigned To" field blank. The idea is that the team will create a Task work item which will be assigned to an individual and the Task will link to the Bug. The Team as a whole will therefore take responsibility for the Bug, not an individual, aligning to Scrum - apparently. I see the down side. The reporting tools built into TFS become less useful when you cannot sort by assigned vs unassigned, let alone sorting by which user Bugs are assigned. Is there a benefit I'm not seeing? Besides encouraging teamwork by putting the responsibility on the team-as-a-whole instead of an individual?

  • Strange problem with libc: undefined reference to `crypt'

    I moved from Archlinux to Kubuntu 12.04 yesterday. I compiled buildroot 2012.08 on Archlinux without any problem. Though on Kubuntu libcrypt seems to be broken. sysvinit can't find it anywhere. glibc-dev and all dependencies are installed. How do I link to libcrypt? Or, which package containts that library? ... bc-gcc sulogin.o -o sulogin sulogin.o: In function `main': sulogin.c:(.text+0x49d): undefined reference to `crypt' collect2: ld returned 1 exit status

  • How will this affect my SEO ranking?

    - by dunc
    I run a fishkeeping website based on a WordPress (PHP) CMS. I've recently put a fairly complex "filter" into place which searches my content for mentions of fish species profiles and turns them into an active link. For example, asdasd this is a test about abdomen to see if the caudal fin will work asdadasdas try again with abdomen and A. panduro and Apistogramma panduro ...becomes asdasd this is a test about abdomen to see if the caudal fin will work asdadasdas try again with abdomen and <a href="/?p=1703" class="link_species">A. panduro</a> and <a href="/?p=1703" class="link_species">Apistogramma panduro</a> On the rest of my website, the species are linked with pretty URLs such as /species/apistogramma-panduro/ but due to the way this filter works, the only information I can get access to is the idof the post. As such, I'm using /?p=1703 or whatever the ID is. What I'd like to know is: how much will this affect my SEO rating/ranking? Will it be detrimental if I don't rewrite the function? Thanks in advance,

    - by chiba
    Most of the visitors to my site are supposed to come from external link with URL my-seite.com/en/var from Facebook ads but Google Analytics shows that most of the landing page is my-site.com/var without en which is the prefix for English version of my site. Am I missing something to configure Google Analytics ? or Facebook has sending the visitors to the wrong URL (by the preview page of the Facebbok ads the URL is set correct with the prefix en)? Any advise are appreciated. Thanks.

  • Can't install ATI proprietary drivers in 12.10

    - by EApubs
    I have a laptop with ATI Radeon 6770M HD Hybrid graphics card. In Ubuntu 12.04, I installed the fglrx driver through "additional drivers" and it worked. (I can even switch GPUs). But in the new Ubuntu 12.10, after installing, Unity won't load. Only the mouse and the wallpaper. If I initialize the settings sudo aticonfig --initial then after rebooting it gives a warning saying I'm in low graphics mode! How to fix this? PS : Earlier i used software source to install the drivers. But when using the terminal, I got this warning : update-alternatives: warning: forcing reinstallation of alternative /usr/lib/fglrx/ld.so.conf because link group x86_64-linux-gnu_gl_conf is broken Update : Filed a bug report in launchpad : https://bugs.launchpad.net/fglrx/+bug/1068661

  • Login and redirect to user home page [migrated]

    - by Rich
    The problem I can't currently solve is when a user logs in. They arrive at the site (index.php) and enter username and password, which gets submitted via a Post form back to index.php - if there are incorrect details then they get an error message. But if successful then I would like them to be taken to their user home page - but I can't do this! I am left presenting them with a link to the home page, which is more than a little clunky. Seems there must be an obviously solution - never seen a site before that didn't redirect! Not sure is the answer is PHp, HTML, or Javascript.

  • should singleton be life-time available or should it be destroyable?

    - by Manoj R
    Should the singleton be designed so that it can be created and destroyed at any time in program or should it be created so that it is available in life-time of program. Which one is best practice? What are the advantages and disadvantages of both? EDIT :- As per the link shared by Mat, the singleton should be static. But then what are the disadvantages of making it destroyable? One advantage is it memory can be saved when it is not useful.

  • Webmatrix fails to connect PHP website to MySQL

    - by Roni
    I downloaded the latest versions of Webmatrix and MySQL. I downloaded a PHP-MySQL Connector: http://dev.mysql.com/downloads/connector/php-mysqlnd/ In the "Databases" Workspace I pressed "New Connection" button and choose "MySQL Connection" In the Dialog box I filled-in all connection details -- It looks like the database was added. But then when I double-click on the database, I get a short error message saying it cannot connect. I tried everything, searched the web... I'm sure it's a very simple question, so please whoever can help I'll be grateful. I think best solution for me would be if someone could please just give me a link to download of: Webmatrix,MySQL,Connector; and instructions on how to install and then how to connect. This would be the safest way to help me.

  • Google showing meta descriptions from other pages in the SERPs

    - by ojek
    Recently I added some content to my website and submitted a sitemap files to Google. Now that Google has indexed those pages, I discovered that some of words and sentences that are listed in Google that lead to my website are having their meta descriptions somehow mixed up. Here is how it works: After I put a sentence on Google to check for my website ranking, I can see a page title in the results of page1, a link to page1, and a description from page2. Since my website is a forum, if Google mixes the links of threads, it leads my users to different kind of material that they were looking for. Is there anything I can do about it?
