Why does starting a program log me out?

- by Bruce McKean

I'm not a computer nerd but have been able to fix Ubuntu/Linux problems in the pass two years with a Google search but this on has me stumped. I upgraded to 12.04 about thirty days ago and all was well except that every time I tried to load KeePassX it would go to the login screen. I installed KeePass2 and all seemed to work. Last week I tried to load Bibble5 (Raw photo editor) and it would try to load and then back to the login screen. After a few days I gave up and downloaded Corel After Shot Pro (Corel's now owns Bibble5) and it has the same problem. Could someone please head me into the steps I need to follow to find out what is the cause? I'm interested in learning more about the Linux system. How to correct any future problems like this? Computer Specification: Processor : 8x Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz Memory : 8155MB (1092MB used) Operating System : Ubuntu 12.04 LTS Graphics Card : GeForce GT 520/PCIe/SSE2

Is the copy/paste approach professionally viable when working with the Google Maps API?

- by Ian Campbell

I find that I understand much of the Javascript concepts used in the Google Maps API code, but then again there is quite a bit that is way over my head in syntax. For example, the geocoder syntax seems to be of Ajax form, though I don't understand what is happening under the hood (especially with lines like results[0].geometry.location). I am able to modify the body of if (status == google.maps.GeocoderStatus.OK) for different purposes though. So, being that I am able to take various code from the Developer's Guide and rework it to an extent for my own purposes, all the while not fully understanding what Google Maps is actually doing, does this make me a copy-paste programmer? Is this a bad practice, or is this professionally viable? I am, of course, interested in learning as much as I can, but what if time-constraints outweigh the learning process?

Manipulating Perlin Noise

- by Numeri

I've been learning about Procedurally Generated Content lately (in particular, Perlin noise). Perlin noise works great for making things like landscapes, height maps, and stuff like that. But now I am trying to generate structures more like mountain ranges (in 2D, as 3D would be way over my head right now) or underground veins of ores. I can't manage to manipulate Perlin Noise to do this. Making a cut off point (i.e. using only the tops of the 'mountains' of a heightmap) wouldn't work, because I would get lumps of mountains/veins. Any suggestions? Thanks, Numeri

Apple prépare un concurrent des Google Glass ? Un dépôt de brevet révèle des travaux sur un dispositif de réalité augmentée

Apple prépare un concurrent des Google Glass ? Un dépôt de brevet révèle des travaux sur un dispositif de réalité augmentée Apple travaillerait sur un système de réalité augmentée semblable aux lunettes Google Glass présentées par le géant de la recherche récemment lors du Google I/O. C'est en tout cas ce que laisse présager un dépôt de brevet de la firme à la pomme qui a été validé ces jours. Le brevet ?Peripheral treatment for head-mounted displays? déposé en 2006, décrit un appareil informatique qui permet de projeter une image à partir d'un dispositif porté sur la tête (casque, lunettes ?)...

Is there a preferred way to set up a virtual Ubuntu server on a desktop?

- by Keith Groben

I love Ubuntu, and as I am searching the internet, I am finding that some questions I have have not been answered yet. One of them is if there is a preferred way to set up a virtual server. I look through the Ubuntu Software Center, but found nothing from the search "Virtual Server" I then searched the internet and found lots of posts to trouble-shoot VMWare virtual servers. So, like a good researcher I looked in the Software center for VMWare. Sure enough I found "user agent" and "view open client". I didn't get sufficient info from the software center. And searching the website only left me scratching my head. I want to install Ubuntu Server Edition. I already have a server, but am cautious "trying out" things on it. So a virtual server sounds like what I need.

How do you coordinate with interaction designers during implementation?

- by Alex Feinman

Programmers are largely responsible for helping move a product from design to implementation. This process is always full of snags: implementation details rear their ugly head and make parts of the design infeasible user feedback on early prototypes leads to changes in the design new technologies alter the field of what is possible, bringing back designs previously thought impossible priorities shift, schedules change, and requirements wander How do you keep design and implementation in contact during the implementation? What processes do you use? Tools? Artifacts? Guidelines? Communication strategies?

MacBook Pro (5) touchpad stops working after upgrading from Ubuntu 10.10 to Ubuntu 11.04

- by Rob

After upgrading from Ubuntu 10.10 to Ubuntu 11.04, my MacBook Pro's touchpad stopped working. It works fine on the login screen, but after logging in it stops working. (Answering my own question, in the hope that it saves someone else a bit of head scratching. I'm a new user, so couldn't answer in a separate post for the next few hours). After the upgrade, your Gnome desktop configuration may have gone awry. There are a few settings which enable or disable the touchpad in certain contexts which may need tweaking to get the touchpad working again. Here's how I got mine working again: Hit Alt-F2, and run 'gconf-editor' Navigate to desktop-gnome-peripherals Ensure that peripherals-touchpad:touchpad is enabled. Ensure that peripherals-bcm5974:disable_while_other_device_exists is disabled. 'bcm5974' is probably specific to my MacBook Pro's hardware, so you may need to search around for variable disable_while_other_device_exists under the entries listed under peripherals. HTH

Why everybody should do Sales!

- by FelixWehmeyer

I speak with many business students and ask them what job they want to get into. Most of them tell me they want a job in Marketing, Management Consulting or Finance. I hardly ever hear “Sales, that is what I want to do”, and I often wonder why. I would like to start with a quote from Zig Ziglar, a successful salesman: "Nothing happens until someone sells something." But to get back to the main point, why wouldn’t you want to get in sales? When people think of sales, they picture a typical salesman in their head and think that selling is scary and all about manipulating, pressuring and pushing someone into buying something they don’t need. Are these stereotypes accurate? I don’t believe so: So why should you want to be in sales? If you think about selling as providing the solution for the problem and talking about the benefits of making a decision, then every job in this world comes out of selling. In every job you deal with coworkers that you want to convince of your ideas or convincing your boss that the project you want to work on is good for the company. These days, consumers and businesses are very well informed about services and products. When we are talking about highly complex products, such as IT solutions, businesses don’t accept your run-of-the-mill salesman who is pushing a sale. These are often long projects where salespeople have a consulting and leading role. Salespeople need to be able to consult companies and customers with their problem and convince a client that their solution is the best fit. Next to the fact that sales, is by far, not as scary and shady as you thought, there are a few points that will make you want to consider a sales career: Negotiating skills – When you are in sales you will learn how to negotiate. Salespeople learn to listen to their customers and try to make them happy, overcoming objections and come to a final agreement that both parties are happy with. Persistence/Challenge – As a salesperson you will often hear a negative answer, in a sales role you will start to embrace this and see a ‘no’ as a challenge not as a rejection. This attitude change can help you a lot in your career, but also in your personal life. You will become more optimistic and gain a go-getter attitude. Salary – As salespeople are seen as the moneymakers for the company, companies often reward their sales teams generously. Most likely in a sales role, you will receive a good basic salary and often you get nice bonuses on top of that based on your performance. Oracle is, for instance, the company that offers the highest average commission in the world. Further you can expect many other benefits as companies know that there is a high demand for good salespeople. Teamwork – Sales is a lot like having your own business, you are responsible for your own territory or set of clients. You are the one who is responsible for the revenue coming from that territory. So in order to gain revenue you will have to work together with many departments and people to make that happen. Every (potential) client could be seen as a different project, and you are the project leader. Understanding customers and the business – From any job that you choose sales will get you the most insight in the market. Salespeople are usually well-connected, talk with different customers and learn about the market and are up-to-date about all latest changes. Even if you want to change to a different role in the long run, you have a great head start as you understand the market and customers like no one else. Job security – Look at all the job postings out there. Many of them are sales-related. So if you want to have a steady job, plenty of choice and companies willing to invest in you, sales could be something for you. Are you interested in exploring a sales career? At Oracle we are always looking for good sales professionals and fresh graduates who want to get into sales! For many languages such as Flemish, Dutch, German, French, Swedish and Norwegian (and more) we are currently looking for graduates who want to develop their career in Oracle. Please have a look at this article for the experience of a Business Development Consultant at Oracle in Dublin.

How Can Someone With Minimum Programming Experience Publish an App of an Existing Program not found in the Software Centre?

- by Brenton Horne

There's a free mathematics software that I would like to see in Ubuntu Software Centre, called, 'Sage.' I have minimal experience in programming, so I'm basically here asking if someone could either tell me how to accomplish this without said instructions being completely over my head or if someone could do it for me. For further information here's the sage homepage: http://sagemath.org/ and the .tar.lzma file for its installation is ~500MB and it takes around 2.2 GB on the HDD when installed, I found at least on 32 bit i386 Ubuntu 12.04 LTS. Any help will be greatly appreciated!

What are the packages/libraries I should install before compiling Python from source?

- by Lennart Regebro

Once in a while I need to install a new Ubuntu (I used it both for desktop and servers) and I always forget a couple of libraries I should have installed before compiling, meaning I have to recompile, and it's getting annoying. So now I want to make a complete list of all library packages to install before compiling Python (and preferably how optional they are). Off the top of my head I can remember these: build-essential (obviously) libz-dev (also pretty common and essential) libreadline-dev (or the Python prompt is crap) But I know there are many more. Please tell me and I'll update.

I'm 15 and I really want to study Computer Science at University, any advice?

- by Jake

I already do a lot of programming in my spare time. I'm confident with PHP, Javascript, jQuery which I use in combination with HTML to create mock-up websites. The specific part of programming I want to get in to is web development/web applications. What I'm asking is since I'm pretty sure this is what I want to do, how can I get a head start? Edit: "If you could tell your 15 year-old self to do something that would benefit your programming career, what would it be?" - I just thought of this and thought it would be a better, more specific question :)

OpenGraph tags and HTML5 validity

- by netmano

I have a HTML5 based page, and I inculded the OpenGraph tags according to it's documentation. Also I checked with Facebook Debug, and it can parse the metadata. But when I use W3C Validator, it reports the OG tags as error: Attribute content not allowed on element meta at this point. <meta property="fb:admins" content="...." /> Attribute content not allowed on element meta at this point. <meta property="og:url" content="http://www...."> They are all in the <head>. I would need my page be "valid" HTML5 and OG tags, as well. Could you help me giving a hint how can it be achieved? UPDATE: The name version also invalid: <meta name='fb:admins' content=''>

Drawing a random x,y grid of objects within a prespective

- by T Reddy

I'm wrapping my head around OpenGL ES 2.0 and I think I'm trying to do something very simple, but I think the math may be eluding me. I created a simple, flat-ish cylinder in Blender that is 2 units in diameter. I want to create an arbitrary grid of these edge to edge (think of a checker board). I'm using a 3D perspective with GLKit: CGSize size = [[self view] bounds].size; _projectionMatrix = GLKMatrix4MakePerspective(GLKMathDegreesToRadians(45.0f), size.width/size.height, 0.1f, 100.0f); So, I managed to manually get all of these cylinders drawn on the screen just fine. However, I would like to understand how I can programmatically "fit" all of these cylinders on the screen at the same time given the camera location, screen size, cylinder diameter, and the number of rows/columns. So the net effect is that for small grids (i.e., 5x5) the objects are closer to the camera, but for large grids (i.e., 30x30) the objects are farther away. In either case, all of the cylinders are visible.

Could someone break this nasty habit of mine please?

- by MimiEAM

I recently graduated in cs and was mostly unsatisfied since I realized that I received only a basic theoretical approach in a wide range of subjects (which is what college is supposed to do but still...) . Anyway I took the habit of spending a lot of time looking for implementations of concepts and upon finding those I will used them as guides to writing my own implementation of those concepts just for fun. But now I feel like the only way I can fully understand a new concept is by trying to implement from scratch no matter how unoptimized the result may be. Anyway this behavior lead me to choose by default the hard way, that is time consuming instead of using a nicely written library until I hit my head again a huge wall and then try to find a library that works for my purpose.... Does anyone else do that and why? It seems so weird why would anyone (including me) do that ? Is it a bad practice ? and if so how can i stop doing that ?

Click event is working in general browsers butt that is needed for iOS and Android, useFastClick is (touch + mouse click). Moreover if you have this event alot in your project you can turn useFastClick off in mobileinit event: $(document).bind("mobileinit", function () { $.mobile.useFastClick = false; }); vclick event is needed to support touch events to make the page changes to happen faster, and to perform the URL hiding. So you need to change something like this $('btnShow').live("click", function (evt) { To : $('btnShow').live("vclick", function (evt) { For more information : http://jquerymobile.com/test/docs/api/globalconfig.html Here you can find full example in this case : <!DOCTYPE ><html xmlns="http://www.w3.org/1999/xhtml"><head> <link rel="stylesheet" href="http://code.jquery.com/mobile/1.0b1/jquery.mobile-1.0b1.min.css" /> <script src="http://code.jquery.com/jquery-1.6.1.min.js"></script> <script src="http://code.jquery.com/mobile/1.0b1/jquery.mobile-1.0b1.min.js"></script> <script type="text/javascript"> //Here you need to use vclick instead of click event $('ul[id="MylistView"] a').live("vclick", function (evt) { alert('list click'); }); </script> <title></title></head><body> <div id="FirstPage" data-role="page" data-theme="b"> <div data-role="header"> <h1> Page Title</h1> </div> <div data-role="content"> <ul id="MylistView" data-role="listview" data-theme="g"> <li><a href="#SecondPage">Acura</a></li> <li><a href="#SecondPage">Audi</a></li> <li><a href="#SecondPage">BMW</a></li> </ul> </div> <div data-role="footer"> <h4> Page Footer</h4> </div> </div> <div id="SecondPage" data-role="page" data-theme="b" > <div data-role="header" > <h1> Page Title</h1> </div> Second Page <div data-role="footer"> <h4> Page Footer</h4> </div> </div></body></html> Hope that helps.

Alternative way of developing for ASP.NET to WebForms - Any problems with this?

- by John

So I have been developing in ASP.NET WebForms for some time now but often get annoyed with all the overhead (like ViewState and all the JavaScript it generates), and the way WebForms takes over a lot of the HTML generation. Sometimes I just want full control over the markup and produce efficient HTML of my own so I have been experimenting with what I like to call HtmlForms. Essentially this is using ASP.NET WebForms but without the form runat="server" tag. Without this tag, ASP.NET does not seem to add anything to the page at all. From some basic tests it seems that it runs well and you still have the ability to use code-behind pages, and many ASP.NET controls such as repeaters. Of course without the form runat="server" many controls won't work. A post at Enterprise Software Development lists the controls that do require the tag. From that list you will see that all of the form elements like TextBoxes, DropDownLists, RadioButtons, etc cannot be used. Instead you use normal HTML form controls. But how do you access these HTML controls from the code behind? Retrieving values on post back is easy, you just use Request.QueryString or Request.Form. But passing data to the control could be a little messy. Do you use a ASP.NET Literal control in the value field or do you use <%= value % in the markup page? I found it best to add runat="server" to my HTML controls and then you can access the control in your code-behind like this: ((HtmlInputText)txtName).Value = "blah"; Here's a example that shows what you can do with a textbox and drop down list: Default.aspx <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="NoForm.Default" %> <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="NoForm.Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form action="" method="post"> <label for="txtName">Name:</label> <input id="txtName" name="txtName" runat="server" /><br /> <label for="ddlState">State:</label> <select id="ddlState" name="ddlState" runat="server"> <option value=""></option> </select><br /> <input type="submit" value="Submit" /> </form> </body> </html> Default.aspx.cs using System; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; namespace NoForm { public partial class Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { //Default values string name = string.Empty; string state = string.Empty; if (Request.RequestType == "POST") { //If form submitted (post back) name = Request.Form["txtName"]; state = Request.Form["ddlState"]; //Server side form validation would go here //and actions to process form and redirect } ((HtmlInputText)txtName).Value = name; ((HtmlSelect)ddlState).Items.Add(new ListItem("ACT")); ((HtmlSelect)ddlState).Items.Add(new ListItem("NSW")); ((HtmlSelect)ddlState).Items.Add(new ListItem("NT")); ((HtmlSelect)ddlState).Items.Add(new ListItem("QLD")); ((HtmlSelect)ddlState).Items.Add(new ListItem("SA")); ((HtmlSelect)ddlState).Items.Add(new ListItem("TAS")); ((HtmlSelect)ddlState).Items.Add(new ListItem("VIC")); ((HtmlSelect)ddlState).Items.Add(new ListItem("WA")); if (((HtmlSelect)ddlState).Items.FindByValue(state) != null) ((HtmlSelect)ddlState).Value = state; } } } As you can see, you have similar functionality to ASP.NET server controls but more control over the final markup, and less overhead like ViewState and all the JavaScript ASP.NET adds. Interestingly you can also use HttpPostedFile to handle file uploads using your own input type="file" control (and necessary form enctype="multipart/form-data"). So my question is can you see any problems with this method, and any thoughts on it's usefulness? I have further details and tests on my blog.

How to Name Groups of Apps on the Windows 8 Metro Start Screen

- by Taylor Gibb

The Windows 8 Start Screen certainly takes some getting use to, however, one of the things that I really miss about the Start Menu was how i was able to categorize my installed applications. While you cant create folders on the Start Screen, you can group your applications. To get started head over to the Metro Start Screen and move your mouse to the bottom right-hand corner, clicking on the small icon. Now right click on the group of apps that you want to name.

How to convert a Bazaar repository to GIT repository?

- by Naruto Uzumaki

We have a large bazaar repository and we want to convert it to a git repository. The bazaar repository contains the folders of each of the interns. Any documentation/code prepared by interns is committed in their directory so there are a huge number of commits. What steps should be performed to securely convert the bazaar repository to a git repository so that we do not lose any commit information. We firstly need to create a backup of the existing bazaar repository and then convert it. Edit: I followed this link: http://librelist.com/browser//cville/2010/2/9/migrate-repository-bzr-to-git/ It's working fine on my system with Ubuntu. But when I try to run it on the actual server it gives me EOF error and crashes Starting export of 1036 revisions ... fatal: EOF in data (1825 bytes remaining) fast-import: dumping crash report to .git/fast_import_crash_11804 Edit 2: I also tried it on a new CentOS system and received the following error fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree. Use '--' to separate paths from revisions

URL Rewrite http to https EXCEPT files in a specific subfolder

- by BrettRobi

I am trying to force all traffic on my web site to use HTTPS, using the URL Rewrite 2.0 module added to IIS 7.5. I got that working and now have a need to exclude a couple of pages from using SSL. So I need a rule to rewrite all URL except those referencing this folder to HTTPS. I've been banging my head against the wall on this and am hoping someone can help. I tried creating a rule to match all URL except those in a nossl subfolder as in this example: <rule name="HTTP to HTTPS redirect" enabled="true" stopProcessing="true"> <match url="(/nossl/.*)" negate="true" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="false"> <add input="{HTTPS}" pattern="off" /> </conditions> <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="Found" /> </rule> But this doesn't work. Can anyone help?

Applying prerecorded animations to models with the same skeleton

- by Jeremias Pflaumbaum

well my question sounds a bit like, how do I apply mo-cap animations to my model, but thats not really it I guess. Animations and model share the same skeleton, but the models vary in size and proportion, but I still want to be able to apply any animation to any model. I think this should be possible since the models got the same skeleton bone structure and the bones are always in the same area only their position varies from model to model. In particular Im trying to apply this to 2D characters that got 2arm, 2legs, a head and a body, but if you got anything related to that topic even if its 3D related or keywords, articles, books whatever Im gratefull for everything cause Im a bit stuck at the moment. cheers Jery
