• View OS X Desktop on windows remotely at higher resolution then hosting machine

  - by Elijha

  I have a new macbook air 11, which I do some web based programming on, I have a windows box with a 1920x1200 display which I'd like to use to view the mac desktop and keep working at home when I can - taking advantage of the higher resolution screen and full sized keyboard/mouse. I don't think VNC or such is the answer I'm looking for as it would restrict the display to the airs 1366x768 - negating the main benefit more lines of text on screen. From some rudimentary googleing I think I'm after some sort of x-windows / x-11 remote display. But I'm not a Linux user and any discussion seems to be about linux os x or windows Linux setups. Can anyone provide a clear set of instructions on how to do this or an application that can do this.

• Are there alternative ways to implementing an "active link" navigation without using server side languages?

  - by Mel

  By "active" I mean to have the link pointing to the current page classed as "active." This way the link's appearance can be modified using css. Is it possible to implement an active link navigation without using a server side language? I would like to only use CSS/HTML/jQuery if possible. If there are, what are those methods? Assuming you want to create the following structure: <ul id="nav"> <li class="active">Home</li> <li>About</li> <li>Contact</li> </ul>

• In Rails models; for symbols get automatically converted to YAML when saving to DB. What is the corr

  - by Ram

  In my model example Game, has a status column. But I usually set status by using symbols. Example self.status = :active MATCH_STATUS = { :betting_on => "Betting is on", :home_team_won => "Home team has won", :visiting_team_won => "Visiting team has one", :game_tie => "Game is tied" }.freeze def viewable_status MATCH_STATUS[self.status] end I use the above Map to switch between viewable status and viceversa. However when the data gets saved to db, ActiveRecord appends "--- " to each status. So when I retrieve back the status is screwed. What should be the correct approach?

• XAMPP on windows 7 not working properly

  - by 404Error

  Hey there, I just installed XAMPP lite on Windows 7. I have two drives - C: for the OS and regular files, and an external drive E:. I installed XAMPP lite on E: (on the root), and its been giving me problems. Apache works well enough, but MySQL doesn't work. When I go to http://localhost/phpmyadmin/, it gives me the following error: Error MySQL said: #2003 - Can't connect to MySQL server on 'localhost' (10061) Connection for controluser as defined in your configuration failed. Any ideas as to what could be the problem? I used the zip file for XAMPP lite, the 32 bit version. This is on Windows 7 Home premium. Thanks!

• Aliasing localhost in Tomcat

  - by Saurabh

  I have a web application "quicker" deployed in Tomcat5.5 version. Usually, I run this application by using url, localhost/quicker and it loads the index.jsp file which is the home page of application. I would like same application to be run using url, www.local.dev.mydomain.com/quicker. Would it be possible by doing some configuration in server.xml or some other place? One way of doing this is could be, modify hosts file in windows as - # 127.0.0.1 localhost 127.0.0.1 www.local.dev.mydomain.com But, I want to this in tomcat manner if possible.

• [FLEX] MVC: choosing a view at runtime

  - by Alberto M

  Hi all, I'm quite new to the MVC design-pattern, and I'm translating all of my old code. I want to move to this pattern because I can change my views according to my needs, but I'm finding difficult to do it at runtime. I found an excellent example of MVC, and all that I do is the following: <mx:ViewStack xmlns:mx="http://www.adobe.com/2006/mxml" resizeToContent="true" xmlns:views="MVC.views.*"> <views:HomeView id="Home"/> <views:SecondPage id="SecondPage "/> </mx:ViewStack> what if I wanted to change (whenever the Controller says so) one of the views, for example the SecondPage view? (Hope I made my point clear)

• How is this problem usually solved without using sever-side scripting?

  - by cyggi

  Simple problem I have so far always solved via PHP: You have a site with header, menu, footer and content field. Header, menu and footer are usually the same for each page. How do you, without PHP or any other server-side language, have the header, menu and footer data exist only in one file? So that for example you don't have ten sites (like home.html, products.html, about.html, ..) all having a copy of the static header and menu in their html files. Now if you want to change the header you have to change ten files. I hope I made my question clear enough, if not please leave a comment :)

• Is there a way to update a database when installing/upgrading an app?

  - by Adam

  I have a main application, and a bunch of sub-applications (they are separate apps, which do not appear on the android home dashboard). I was planning on having a SQLite DB which the main app maintains, and get a list of available sub-apps from. Is there a way to update this main database as the user installs the sub-apps? Two alternative I was thinking of include: User installs the sub-apps via the main app, which would then update the DB. Rather than use the DB to find all installed sub-apps, have each sub-app declare a category, and use intents to query for all applications which match that query (is this even possible? if so, advice is welcomed). Thanks!

• SVN always getting errors when I commit (Subclipse)

  - by jax

  I have setup svn on my server and Subclipse at home. I am the only developer and am mainly using it for the backup and versioning features. Everytime I commit my changes I get eighter: Out Of date errors or Tree conflicts Sometimes I even delete files and they don't delete on svn, in a directory hierarchy only the very last item will delete so I have to delete each folder one at a time. How do I avoid these errors in the future? Update: Another problem I am having is that sometimes eclipse seems to sync with the server so that when I refactor a filename it goes off to the server and does something and makes me wait, which is annoying. And for clarity, this is a typical operation: I might change a filename, move a file to a different folder then change the contents of a file. I select the 'Team menu' and click 'commit'. Then I get all these errors above.

• Check directory exists and if it doesnt choose an image

  - by Andy

  I have this code so far which perfectly but relies on there being a directory in place: $path = '/home/sites/therealbeercompany.co.uk/public_html/public/themes/trbc/images/backgrounds/'.$this->slug; $bgimagearray = array(); $iterator = new DirectoryIterator($path); foreach ($iterator as $fileinfo) { if ($fileinfo->isFile() && !preg_match('\.jpg$/', $fileinfo->getFilename())) { $bgimagearray[] = "'" . $fileinfo->getFilename() . "'"; } } I need to work in a bit at the top so that if the directory doesnt exist it defaults to the images sat in the root of the background directory... Any help would be appreciated.

• Change IP where domain is pointing

  - by Christian Sciberras

  This is probably a very strange request. I need to programmaticaly (via code) change the IP where a domain name is pointing to. IE: xyz.com points to 100.100.100.100 setIP('xyz.com','100.100.100.100'); I know this [code] is practically impossible, however, what I need is to do this via domain host API etc or other possible ways you might think of. I'd be happy even if it weren't anything more then sending an email to the DNS owner/host. Do you know of anything the like or which might help? (nb: considered throwing this at ServerFault, but felt it more at home here ;) ) Cheers!

• How come the [L] flag isn't working in my .htaccess file?

  - by George Edison

  Here are the rules: <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^$ index.php?action=home [L] RewriteRule ^[\w\W]*$ error.php [L] When a page matches the first one, it is supposed to ignore any other further rules. Yet accessing / results in error.php being invoked. Commenting out the second rule works as intended - the page redirects to index.php. What am I doing wrong? Also: is there a better way to write the last line? It's basically a catch-all.

• Artificial Intelligence - What to put in, or leave out, and what can be inferred?

  - by D Scott

  I was having a discussion with a coworker (while we were programming) about AI. We were talking about emotions/feelings and if you should choose to leave any out. I asked him, "Would you leave out racism or hate?" and if you did leave those out, what, if any, other emotions might lead to the AI learning the left out emotions or feelings. Should you PROGRAM in measures to stop the AI from learning those feelings? If you teach Love, does it need to know hurt? Or would it learn hurt? If it then knew Hurt would it connect it with Dislike, Hurt and Dislike could that then lead to some other non-programmed emotion? Such as hate? All while tele-commuting from home.

• Can I use GNU Screen completely transparently/automatically?

  - by dreeves

  Screen is amazing, of course, but I don't want to have to think about it. I often ssh to a machine, start doing a bunch of stuff, and then think "gosh, I wish I had thought to start a screen session before doing all that so I could reconnect to this from home later". I'd like to have screen automatically started whenever I log in to a machine. And when I get disconnected, I want to be able to immediately and simply reconnect without fussing with "screen -ls" and "screen -dr". I have a script that implements one solution to this problem which I'll post as an answer. I'm interested to see other approaches.

• javascript code to prevent screensaver from starting

  - by gertjan

  Hi all, I am completely new to javascript programming and I have a question that I didn't manage to find an answer for anywhere. I have recently put together a simple slideshow to view the photos remotely that I host on my home computer. This by itself works fine. The problem I run into is that when I'm viewing photos I don't interact with the hardware, which after some time causes the monitor to switch off. This is particularly annoying when watching photos on my mobile phone. My question is: is there a way to prevent this from happening? I am thinking in the direction of faking a mouse or other event every time I refresh the photo, but I have no clue how to do that and if it is possible. Any help is greatly appreciated!

• Twitter URL encoding

  - by Rich

  Hi, We're about to launch a little twitter Christmas competition, and I've run into a little snag. To enter, people will need to post a tweet in the following format: @user blah, blah, blah #hashtag Currently, I have a form where they enter their answer (the blah, blah, blah) and a PHP script which encodes the entire statement and adds on the twitter url: http://www.twitter.com/home?status=%40user%20blah%2Cblah%2Cblah%20%23hashtag Then takes the user to twitter and puts the status in the update field. However, whilst the spaces (%20) are decoded fine the @ and # characters remain as %40 & %23 respectively, even when the tweet is posted. I cannot put the actual characters in the url as twitter mistakes this for a search. Is there any way to solve this? I'd like to do it without requiring username & password etc if possible. Any help will be greatly appreciated.

• Pick an image from the Gallery

  - by Steve Jones

  I have seen a lot of posts about this, and it seems like the code below should work. I have created an SD Card image and added it to the emulator (and that works fine). Intent intent = new Intent(Intent.ACTION_PICK); intent.setType("image/*"); //intent.setAction(Intent.ACTION_GET_CONTENT); startActivityForResult(intent, 1); It does launch and allow selection of images, but when I click on an image, everything exits and the emulator returns to the home screen, not the back to my app. My onActivityResult is never called either. What am I missing?

• how to deal with async calls in Ajax 4.0(using jquery?)

  - by dexter

  in my code i have done something like this. $.get('/Home/Module/Submit', { moduleName: ModName, moduleParameters: moduleParameters }, function(result) { $("#" + target).html(result); }); when i put alert in the function(result) {..} it shows html perfectly(both in alert and at the 'target'-on the .aspx page) BUT when i remove the alert.. on the page the 'html' don't appear or appear randomly (this method is called multiple times) i think that the 'result' comes to function asynchronously thats why it is not bind with the respective 'div' however in the last iteration it gets bind every time. can we make process stop until data gets bind? or is there any functionality (like alert) which can make data bind.. without disturbing UI (unlike alert)?

• Would you tell your prospective boss your SO username?

  - by Sebi

  Today I met a friend who is also using stackoverflow. He had a job interview today at a small business and during the interview, the prospective boss asked him how he assures that he's alawys up-to-date concerning technical questions and what he's doing to seek for a solution for a problem he can't solve by its own. Besides some magazines, journals, books and blogs my friend also mentioned stackoverflow. The prospective boss seems very interested about that and asked him if he could tell him his username. It appears that was the most difficult during the whole interview ;) Would you tell your prospective boss your username? An the pro side one can mention that the boss sees that you're very involved in your business and community but on the other hand it is a really private thing and you cant post anymore in thread like "what was the worst working environment?" My friend circumnaviagted this question by a rather lame answer (more or less: i use autologin, thats why i have to check the username later at home, ill maybe send you an email)

• Changing careers to Software Engineering.... Wise?

  - by Phil

  Hello everyone, I notice this site has a wealth of software professionals and I am investigating a career change to Software Engineering: *Particularly, I would like to know how likely one would be able to work from home or another country over the internet. Is this something that can be done and what does it usually entail? (time?,experience?, specific companies?, etc) *Currently, I am a teacher but always had a passion for tech. I am interested in a MS - Software Engineering program designed for individuals based from another field. Is this a wise degree to obtain? Would I be just wasting my time and money obtaining this degree? (I'm suspicious about this program and the feasibility of obtaining employment without a healthy CS background) Thanks for any assistance you can provide!

• VirtualBox snapshots

  - by CodeMedic

  Heres what happened. I had a snapshot on which I was working from within a linux VM. A friend requested a clean VM as a clone of mine. So I closed / shutdown my running VM, made a copy of the Disk1.vdi along with the snapshots ({uuid}.vdi). Then I restarted the VM and did merged snapshots, deleted my home directory and made a tar+bz2 for my friend. Then after I restored my backups, I am not able to mount my snapshot. The VM seems to boot from my version before snapshot. I cant seem to find a way to mount back my snapshot. Any idea how to make VirtualBox see the snapshot and mount it?

• Maintain Constant Title Across Website

  - by Jason

  If I am creating a website in ASP.NET, is it possible to programmatically set the title of the page be some predefined value with some extra information tacked on? For example: Home Page Title = Site Name Links Title = Site Name: Links Stuff Title = Site Name: Stuff Basically, whatever I defined as the main title on the page I'm currently on, I want to tack ": Name" onto the end of the title so it stays consistent across the website. I was thinking of defining it as a ContentPlaceHolder and wrapping some logic around it, but it doesn't appear to work how I thought it would (AKA, not at all).
