• How can i run my .LÖVE game directly from the lua interpreter?

  - by jonathan

  I've just started with LOVE and LUA , i'm interested in LOVE because i want to play around with something different from my dayjob(i'm a webdeveloper) and since it uses LUA and is interpreted , i though it would be a great way to try out the API. but i couldn't find how to run my .LÖVE game directly from the lua interpreter? i'm finding it bothersome to package the game each time i make a little test with the API. since i couldn't find the answer i'm asking, but maybe i'm serching for the wrong terms, if this it is a simple matter like "import the library" or set the global, i'll gladly remove my question.

• Why make JavaScript class based?

  - by Carnotaurus

  JavaScript is a prototype language. To turn it into a class based language adds little value? I am not talking about best-practice here. I remember reading an article from way back, which claimed that the class-based worldview is perceivably more flawed than the one of prototypes. My summary can be found here: http://carnotaurus.tumblr.com/post/3248631891/class-based-javascript-or-not. I am resisting to use the class-based jQuery add-on and other attempts at faciliating class-based JavaScript. Peer pressure is strong but is there a stronger theoretical or practical reason why I stop resisting?

• Is it common to prototype in a higher level language?

  - by Mark Canlas

  I'm currently toying with the idea of embarking on a project that far exceeds my current programming ability in a language I have very little real world experience in (C). Would it be valuable to prototype in a higher level language that I'm more familiar with (like Perl/Python/Ruby/C#) just so I can get the overall design going? Ultimately, the final product is performance sensitive, hence the choice of C, but I'm afraid not knowing C well will make me lose the forest for the trees. While searching for similar questions, I noticed one fellow mention that programmers used to prototype in Prolog, then crank it out in assembler.

• Advice for transitioning into a Java developer position from doing other types of web development?

  - by Rick

  I've been doing web programming and currently work at a company working with mainly PHP and Javascript. For a little while now I've been becoming more and more frustrated with the shortcomings of this type of development and want to move to a company with a more defined development process that values doing things the "right way" such as using Unit tests, dependency injection / IoC, etc. I've been learning JEE / Java as much as I can on my own time but would really like to make a switch to doing this as my career and leave behind the PHP world altogether. I'm just wondering if anyone can give me advice on which things to put my main focus on right now to make myself marketable as an entry level Java developer. Basically, I feel that I'm not really learning anything new at my current job that will benefit me and its only making me more and more frustrated so I figure if there is any way to position myself for a transition I would rather do it sooner than later. Thanks for any advice.

• Is there a way to add Google Docs-like comments to any web page?

  - by Sean

  You know the comments on Google Docs word processing documents? And how it creates a little discussion over in the right-hand margin? I love it. Great for collaboration. I want to free it from Google Docs so I can use it with clients to discuss mock-ups or scaffolded websites. Searching Google for "add comments [or discussions] to any website" only gets you results for adding blog-like comments (Disqus, JS-Kit, etc.) Anyone know of a solution for what I'm after here?

• An alternative way to request read reciepts

  - by lavanyadeepak

  An alternative way to request read reciepts Sometime or other we use messaging namespaces like System.Net.Mail or System.Web.Mail to send emails from our applications. When we would need to include headers to request delivery or return reciepts (often called as Message Disposition Notifications) we lock ourselves to the limitation that not all email servers/email clients can satisfy this. We can enhance this border a little now, thanks to a new innovation I discovered from Gawab. It embeds a small invisible image of 1x1 dimension and the image source reads as recieptimg.php?id=2323425324. When this image is requested by the web browser or email client, the serverside handler does a smart mapping based on the ID to indicate that the message was read. We call them as 'Web Bugs'. But wait it is not a fool proof solution since spammers misuse this technique to confirm activeness of an email address and most of the email clients suppress inline images for security reasons. I just thought anyway would share this observation for the benefit of others.

• SharePoint 2010: Taxonomy feature (Feature ID &quot;73EF14B1-13A9-416b-A9B5-ECECA2B0604C&quot;) has not been activated

  - by Kelly Jones

  I ran into an error message in SharePoint 2010 that took me a few minutes to figure out.  I was working on a demo of SharePoint 2010’s managed metadata and getting an error when I was adding a Managed Metadata column to a library.  A little Google research turned up this blog post: The Taxonomy feature (Feature ID "73EF14B1-13A9-416b-A9B5-ECECA2B0604C") has not been activated. As Michal Pisarek pointed out last June, you get the error because the Taxonomy feature isn’t activated.  Like Michal, I’m not sure how this happened to my installation, but the fix he documented works. (Activating the feature using STSADM)

• Is MVC now the only way to write PHP?

  - by JasonS

  Hey... its XMAS Eve and something is bugging me... yes, I have work on my mind even when I am on holiday. The vast amount of frameworks available for PHP now use MVC. Even ASP.net has its own MVC module. I can see the attraction of MVC, I really can and I use it frequently. The only downside that I can see is that you have to fire up the whole system to execute a page request. Depending on your task this can be a little wasteful. So the question. In a professional environment is this the only way to use PHP nowadays or are their other design methods which have alternative benefits?

• Unity iOS optimization and draw calls

  - by vzm

  I am curious of what methods I should approach in optimizing my Unity project for iOS hardware. I have very little image effects running (directional light with low res shadows) and I used the combine children script from the standard assets to lessen the load on the CPU. My project currently runs with 45-57 draw calls at non-intensive segments and up to 178 at intensive segments. I heard that static batching relieves some of the stress, but the game has the environment moving around the player instead of the player moving around the environment. Is there any alternative that I may look towards to improving the draw call number?

• What is the best way to become a professional in PHP and Website Building?

  - by Mr.TAMER

  I would like to become a professional in php, I have learned nearly all about the language syntax and concepts and I have a good knowledge in C and C++, which made it easier to become familiar with PHP. (Of course, I learned MySql too.) But I don't feel like being able to build even a little good website of my own! It looks like PHP is all about knowing lots of functions and using them, while in fact I don't think it's like that, is it? How can I become a professional in PHP and Website Building? I would do anything and spend whatever amount of time required for that. EDIT I've also a very good knowledge in HTML and a normal knowledge in CSS and JavaScript. Sorry for not mentioning that, I just thought it was implicitly included.

• What's the correct MAAS DHCP configuration?

  - by k to the z

  I've set up a MAAS controller by following this documentation: http://maas.ubuntu.com/docs1.4/cluster-configuration.html However, when I got to the DHCP configurations I was a little puzzled. The controller I created is at 172.16.142.61. It looks like that's the address for the "IP" text field. Going down the rest of the list I'm unsure of though. Should I just put in the subnet/broadcast/router (is that the gateway?) that the MAAS server resides in or am I suppost to just list the static address of the MAAS server and then define my own "virtual" subnet in the fields below?

• Broken links in content reports when tracking subdomains with Google Analytics

  - by Rob Sobers

  I have a tracking code that I use on my main site and my blog, which is on a subdomain: www.example.com blog.example.com I have a single profile in Google Analytics. I use advanced segments to look at traffic to the main site vs. traffic to the blog. Problem 1: When I'm browsing my content reports under Standard Reporting, the "Page" column doesn't show the top-level or sub-domain, so I can't differentiate www.example.com/index.html from blog.example.com/index.html easily. According to the docs, this filter is supposed to make GA prepend the hostname to the page URL in your content reports, but it doesn't seem to work. Problem 2: When I click on the little "Open in new window" icon next to a given page in a content report line, it always assumes the page lives on www.example.com, so I get 404s when the page is actually on blog.example.com. Is there a good solution for these subdomain tracking problems?

• How to get average network load instead of instant

  - by Adam Ryczkowski

  Welcome, I use conky to see network load statistics with sampling every 8 seconds in order to get somewhat more smooth history chart. Unfortunately, all values i get are not average for this 8 second period, but they are sampled from much smaller time span, so charts are the same choppy, as if they were sampled from 1 second or less. Is there any way to get conky (or at least System Monitor) display system properties averaged over specified amount of time, just like Windows' task manager does? I would like to have conky display hard drive usage from iostat, but there will be little use if it, if conky reports instant values not averaged over time.

• disable shutdown/suspend if there is other user logged in via ssh

  - by Denwerko

  I remember that in versions of ubuntu around 9.04 was possible to disable user to shutdown ( and maybe suspend too ) system if there was other user logged in.Something like policykit or similar. Is it possible to do in 11.04 ? Thanks edit: if someone needs ( for own risk ), little change in /usr/lib/pm-utils/bin/pm-action will allow user to suspend machine if he is only user logged in or when user will run sudo pm-suspend. Probably not best piece of code, but for now works. diff -r 805887c5c0f6 pm-action --- a/pm-action Wed Jun 29 23:32:01 2011 +0200 +++ b/pm-action Wed Jun 29 23:37:23 2011 +0200 @@ -47,6 +47,14 @@ exit 1 fi +if [ "$(id -u )" == 0 -o `w -h | cut -f 1 -d " " | sort | uniq | wc -l` -eq 1 ]; then + echo "either youre root or root isnt here and youre only user, continuing" 1&2 + else + echo "Not suspending, root is here or there is more users" 1&2 + exit 2 + fi + + remove_suspend_lock() { release_lock "${STASHNAME}.lock" Question still stands, is it possible to forbid shutdown or suspend when there is more than one user logged in ( without rewriting system file )?

• Web development for people who mainly do client side..

  - by kamziro

  Okay, I'm sure there are a lot of us that has plenty of experience developing c++/opengl/objective C on the iPhone, java development on android, python games, etc (any client side stuff) while having little to no experience on web-based development. So what skillset should one learn in order to be able to work on web projects, say, to make a facebook clone (I kid), or maybe a startup that specializes on connecting random fashionistas with pics etc. I actualy do have some experience with C#/VB.net back-end development a while back, but as part of a team, I had a lot of support from the senior devs. Is C# considered a decent web development language?

• Assign subdomains to seperate ports on web server

  - by Michael Frank

  I have set up an Abyss web server as a little experiment, and I want to know if it is possible to assign subdomains to different ports on the machine the web server is running on. I have a couple webUIs that I'd like to assign subdomains: 192.168.1.1:8000 becomes example.com/webui1/ 192.168.1.1:8001 becomes example.com/webui2/ The webUIs are available by accessing their ports via example.com:8000. I have tried using a reverse proxy, but it seems that this is only usable on one internal IP at a time. What other options do I have?

• Gnome panel hides window titlebar.

  - by Xorty

  I moved my laptop screen "below" external screen (was using left/right config before). There's a little problem. When my gnome panel is on top of laptop screen, all windows I maximize "drawn" under top gnome panel. Therefore, I cannot see window titlebar. I tried suggested fixes as metacity --replace and so on, but none worked. When I move my taskbar to bottom it works just fine. Any ideas? Thank you.

• Ubuntu 12.10 desktop/interface not showing on VirtualBox VM after login screen

  - by Jake

  I'm having some trouble with getting my Ubuntu to work on a VirtualBox VM. I made a clean installation of Ubuntu 12.10 on a VM without any errors. I arrive at the login screen, as soon as I press enter it does it's little loading thingy and then screen goes black, then this is all I get: http://i.imgur.com/zULUI.jpg I can access the terminal and pretty much all the other features through it, but I would like to have the GUI properly working. I've been looking around the web and looking at various fixes to similar problems, but can't seem to get it to work. I'm thinking this problem might have to do with the graphics? I'm running Windows 8 Pro as host, if that helps, might be some compatibility issues with VirtualBox in W8... Thanks in advance!

• How to manage a growing team?

  - by Andra

  I'm the admin assistant of the CTO and our organization has recently experienced a lot of growth. Within six months, we have merged with another organization and our Dev team has grown from 8 to 16, with another 8 people in QA. What we're dealing with now is a highly technical individual, with little patience, managing a much larger team than he's accustomed to, 40% of which is junior as well as an increase in the number of projects. Needless to say, my boss is being pulled in too many directions at once. How can I help him manage his workload and his team so that the team feels they're getting enough help and support and remain effective? Also, where can I find additional resources on managing a growing team?

• 12.04 64 bit: Keybord not responding for about 20 seconds at startup/beginning of session

  - by Danilo

  I am running Ubuntu 12.04 64bit. When I get at the login screen and try to type the password for my user, I cannot type anything for about 20 seconds. After that, the keyboard starts responding and everything works fine. Mouse is responding normally as well as all buttons of the login interface (time/calendar, session selection (Unity/Unity 2D), etc.). What could be the reason for this behavior? How can I solve this temporary freeze of the keyboard so that I can type my password immediately without having to wait each time? Thanks for your time. EDIT: I tried auto login, but the problem is still there: the Desktop loads but even there, if I try to type something in the dash or anywhere else, I must wait about 20 seconds before I can actually start typing. Can the issue be related to some keyboard modules that get loaded little bit "too late"?

• What are my tool options to prototype a 2D online multiplayer game?

  - by Asher Einhorn

  I'm looking for the best tool to allow me to quickly put together a 2D game that relies largely on networking. It's extremely likely that this game will require a server side program to constantly run. I have little experience with these things and since it's a prototype i'd like the easiest options for achieving this. I am looking to make this game for the web and mobile devices, although at present I only have access to ios hardware, (no android etc). I just want to get the bare bones of this set up so I can test it from the earliest opportunity to see if it's fun. EDIT - doesn't unity have some inbuilt networking stuff in it?

• Using source code with no license

  - by nathansizemore

  I've recently come across a publicly viewable project on Github that has no license associated with it. In this repo, there is a file with the logic and most of the code needed to work as a piece of a project I am working on. Not verbatim, but about 60% of it I'd like to use with various modifications. Once my code base is a little bit more stable, I plan to release what I've done under the WTFPL License. I've emailed the repo owner, and so far have not gotten a reply. I know I have the rights to fork the repo, but if I release a stripped down and modified version of the other project's file with mine, under the WTFPL, am I infringing on copyrights? Per Github's Terms of Service, by submitted a project on Github and making it viewable to the public, you are allowing other users to see and fork your project. Doesn't say anything about modifying, distributing, or using the fork. And at what point of modification to the original does it become owned by me?
