  • How to disable automatic login?

    - by iammilind
    I was playing around with "User accounts" and somehow set automatic login. Now, when I start my PC, it just has one button named as "login". Clicking that button, directly logs me in to my PC. There is no music or no asking for password while logging in. As a side effect, it asks me separately for keyring password How to disable auto login and make login/keyring password unified again like before? NOTE: Attempting to disable Automatic Login from System Settings User Accounts does not work. This is the content of my /etc/lightdm/lightdm.conf (where I have commented the autologin for my username mgandhi): [SeatDefaults] greeter-session=unity-greeter user-session=ubuntu #autologin-user=mgandhi

  • Silverlight and Windows Phone 7 Sessions from MIX 10

    I had a great time at MIX 10 last week meeting so many people and being part of so  much of the activities. One of the side effects is that it was next to impossible to catch all of the great content while at MIX, so Ive been catching up by watching many of the videos online. Here is a list with all of the Windows Phone 7 and Silverlight sessions where you can grab the videos and/or slides.   Title WMV ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Retrieve .Net Control ID in Javascript

    - by Vipin
    Originally posted on: http://geekswithblogs.net/Vipin/archive/2013/07/24/retrieve-.net-control-id-in-javascript.aspxIf you need to retrieve a client ID of an asp:net control in a javascript function, then you can use the below function - function $$(id, context) { var el = $("#" + id, context); if (el.length < 1) el = $("[id$=_" + id + "]", context); return el; }   var tempDotNetControl = 'aspTextTemporary';   var ClientSideID = $$(aspTextTemporary); Please bear in mind, this function is useful if you want to retrieve client ID of a different DotNet control based on some condition, otherwise if it’s always static then you can just use <%= aspTextTemporary.ClientID %>"

  • Meta Description or Title For Post Contents

    - by Raj
    I have a site that has posts without titles. You can think of them as being a lot like Twitter tweets. Should I put the post contents in the meta title tag or the description tag? If I put the post contents in one of the tags what should I put in the other? My challenge is that we have very short amounts of content with no titles. I want to avoid having too many duplicate titles or descriptions. We have things like user name, full name, date, etc.

  • How can I set my linux box as a router to forward ip packets?

    - by UniMouS
    I am doing a network experiment about ip packet forwarding, but I don't know why it does work. I have a linux machine with two network interfaces, eth0 and eth1 both with static IP address (eth0: 192.168.100.1, eth1: 192.168.101.2). My goal is simple, I just want to forward ip packets from eth1 with destination in subnet 192.168.100.0/24 to eth0, and forward ip packets from eth0 with destination in subnet 192.168.101.0/24 to eth1. I turned on ip forwarding with: sysctl -w net.ipv4.ip_forward=1 my routing table is like this: # route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.100.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.101.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 But, when I try to ping from 192.168.100.25 to 192.168.101.47, it does not work.

  • Is type safety worth the trade-offs?

    - by Prof Plum
    I began coding in in Python primarily where there is no type safety, then moved to C# and Java where there is. I found that I could work a bit more quickly and with less headaches in Python, but then again, my C# and Java apps are at much higher level of complexity so I have never given Python a true stress test I suppose. The Java and C# camps make it sound like without the type safety in place, most people would be running into all sorts of horrible bugs left an right and it would be more trouble than its worth. This is not a language comparison, so please do not address issues like compiled vs interpreted. Is type safety worth the hit to speed of development and flexibilty? WHY? to the people who wanted an example of the opinion that dynamic typing is faster: "Use a dynamically typed language during development. It gives you faster feedback, turn-around time, and development speed." - http://blog.jayway.com/2010/04/14/static-typing-is-the-root-of-all-evil/

  • Naming your unit tests

    - by kerry
    When you create a test for your class, what kind of naming convention do you use for the tests? How thorough are your tests? I have lately switched from the conventional camel case test names to lower case letters with underscores. I have found this increases the readability and causes me to write better tests. A simple utility class: public class ArrayUtils { public static T[] gimmeASlice(T[] anArray, Integer start, Integer end) { // implementation (feeling lazy today) } } I have seen some people who would write a test like this: public class ArrayUtilsTest { @Test public void testGimmeASliceMethod() { // do some tests } } A more thorough and readable test would be: public class ArrayUtilsTest { @Test public void gimmeASlice_returns_appropriate_slice() { // ... } @Test public void gimmeASlice_throws_NullPointerException_when_passed_null() { // ... } @Test public void gimmeASlice_returns_end_of_array_when_slice_is_partly_out_of_bounds() { // ... } @Test public void gimmeASlice_returns_empty_array_when_slice_is_completely_out_of_bounds() { // ... } } Looking at this test, you have no doubt what the method is supposed to do. And, when one fails, you will know exactly what the issue is.

  • Using an old penalized domain for a new website

    - by MiladSafaei
    I had a website with 2 domains like these: firstdomain.com and first-domain.com. The main domain was first-domain.com and the other one was 301 redirected to first one. The main domain got a Google Penguin penalty some months ago. I uploaded the site on an new domain and removed Google index of old domain by using the remove URL tool in Webmaster Tools. Now, I want to use firstdomain.com (which was redirected to the penalized domain) for a new and fresh website with new and perfect content. Is it probable that history of this domain affects the new website and harms its ranking?

  • How do I grep in a variable?

    - by Ashfame
    How to do a grep in a variable? I have stored the wget output in a variable and I need to extract out some strings from it. Like the content of the variable is upgrade http://wordpress.org/download/ http://wordpress.org/wordpress-3.0.5.zip 3.0.5 en_US 4.3 4.1.2 I need to check if the string contains the word upgrade, so I can do a simple grep and then check the exit status of it by $? and proceed. But how can I get the value 3.0.5 which is actually the fourth word? And how to actually grep in a variable?

  • What functionality should I use in OpenGL 2.0?

    - by Jeffrey
    Considering OpenGL 2.1, we all know that glBegin and glEnd are the devil. Should I use only VBO to render 3d primitives (I can't find VAO in that version, weren't there already?)? Should I still use the matrix stack (why not?)? Should I still use glFrustum? Can I take advantage of shaders in GLSL 1.20? Where can I find a tutorial for VBO in OpenGL 2.1 and the "correct" way of programming in it? Also how am I supposed to animate something. Like a cube moving around an object or a player moving in the scene (static vbo data + shader?)? Note: Take your time to answer this question, I'll accept an answer tomorrow.

  • ADF is YouTubed

    - by Chris Muir
    A blog post along the lines of "your wishes are our command". ADF developers are hopefully aware of our ADF Insider Essentials recordings, a page full of presentations from small to large topics on all-things-ADF.  A couple of customers have pointed out these recordings aren't accessible via the iPad and other Apple OSX devices thanks to the recordings being wrapped in an Adobe Flash applet. To satisfy this need we've now uploaded all of the videos as MP4s to our ADF Insider Essentials YouTube channel for your iPad viewing pleasure.  So now regardless if you're sitting at your PC or on the couch with your iPad, you can enjoy my horrible Aussie accent amongst the more professional ADF presentations from my colleagues ;-) Make sure to subscribe to the YouTube channel to receive notifications of newly uploaded content

  • Web Host for Small Rails-based CMS site [closed]

    - by clem
    Possible Duplicate: How to find web hosting that meets my requirements? I am building a site for someone that uses a Rails-based content management system that I built myself. All of the Rails deployment experience I have so far has been over small intranets. I'm looking at web hosts like rackspace, because it seems like they're well-suited for Rails deployment. However, for a site that's not going to have more than a couple of hundred hits a month (if even that), I'm not sure it's necessary. I've also used Dreamhost's Phusion Passenger deployment for small projects before, but it seems barely functional and not well-supported, and I've also used Heroku for deployment, but I think a regular web host may do a little bit better, as they'll need things like Google Apps for Gmail set up. If anyone could provide some guidance on this, I'd greatly appreciate it. I get confused when I see things on rackspace like "1.5c/hour", because I'm not sure how that gets computed.

  • Does XNA/MonoGame have a text caching mechanism, or has an open source one been implemented?

    - by Casey
    I'm playing around with MonoGame, and I've noticed the SpriteFont class draws static text very inefficiently. Each time the text is drawn the spacing is recalculated. This isn't a big deal on my quad core PC, but on mobile applications it might be a problem. Before I go and program some text which caches the arrangement of its letters in an array and then feeds that array to the SpriteBatch, I would like to make sure there isn't something available to do this already, either in MonoGame itself or a class someone has implemented and made available for general use.

  • Procedural object generation and unique identification

    - by 2080
    My question relates to procedural content generation and data management of the emerging objects in a database. I assume a networked game, with a server-client model. Unspecified objects in the game world are generated while the game is running with procedural algorithms (for example perlin noise). The players (/clients) can modify the properties of these objects, but have to notify the server of these changes. How could this communication address unique objects, so that both the server and the client know of which object they are speaking? Not only the inner properties of the objects can differ, but also visible, such as the position. When the player wants to select one of these objects the game has to find out the id - does anyone know which methods or algorithms can accomplish that?

  • How to make Pokémon White 3D effect?

    - by Pipo
    I just wondered how to create a 3D effect similar to Pokemon White/Black? It seems to be not polygon based, but created just with sprites. If the perspective changes the sprites stay sharp and don't get blurred. How can I archive this? Source: https://www.youtube.com/watch?v=fZEPUPYOnRc&feature=youtube_gdata_player Edit: Wow, two downvotes because I used a video instead of screenshots? Don't get me wrong, I thank you, because you want to help me, but the 3D effect can be better understand in motion. Anyway, here is a screenshot: http://wearearcade.com/wp-content/uploads/2011/03/pokemon-black-white-starter-town.jpg So, if this is a hardware limitation, how can I archive this o na different hardware, e.g. a HTML5 game? Thank you.

  • Is it possible for a web-server to send more files than requested for, and have the browser accept them?

    - by Osiris
    I've created a basic web server for a school project, and it serves static content without a problem. I thought of having the server parse all htm/html files for links to .js/.css/image files, and send these files to the client without these files being requested by the client later. eg. The browser requests: index.htm The server responds with intex.htm and image.jpg I modified the server to send two distinct http responses for a "GET /index.html HTTP1.1" (one for the html page and one for the image), but the browser ended up requesting the image when it was good and ready. Is there any way to bypass this? (use a multipart response, perhaps) Will these files be accepted by most browsers, or will they be rejected for security reasons?

  • Job Search Engine Url Structure Issue [closed]

    - by Justin
    Possible Duplicate: What is the best stucture of SEO friendly URL? I am working on a job board, and i'm trying to figure out a good design for URL structure. Some things that I have found through research: 100 - 150 Chars long is ideal 3-5 words in your url, according to Matt Cutts Use .htaccess to force clean urls Do not duplicate data (important) Clean and precise, describing the content Use hyphens On the homepage, I try to detect the users location based on IP, but this isn't always accurate, and not always reliable. So until they put in their city/location, I can't always use this structure but this is potentially work-able. For Searching, a form post to a results page: domain.com/jobs/[city]/[search] ie: domain.com/jobs/toronto/sales manager/ OR domain.com/search/jobs/toronto/sales manager/ or do I remove the word JOBS and just use Search. I trying to keep good search terms in the URL, but also keep it clean and concise. Can someone give me some feedback and thoughts to 'why'...

  • Shouldn't storage classes be taught early in a C class or book?

    - by Adam Mendoza
    Shouldn't storage classes be taught early in a C class or book? I notice that a lot of books, even some of the better ones, covert it toward and end of the book and some books just add it as an appendix. I would teach it together with variables. This is so foundational and I think unfortunately many do not make it that far in a book. Now that auto has a different meaning (vs being optional) it may confuse people that didn't realize it has always been there. for example: C Programming: A Modern Approach 18.2 Storage Classes 401 Properties of Variables 401 The auto Storage Class 402 The static Storage Class 403 The extern Storage Class 404 The register Storage Class 405 The Storage Class of a Function 406 Summary 407

  • Rules for Naming

    - by PointsToShare
    © 2011 By: Dov Trietsch. All rights reserved Naming Documents (or is it “Document, Naming”?) Tis but thy name that is my enemy; Thou art thyself, though not a Montague. What's Montague? It is nor hand, nor foot, Nor arm, nor face, nor any other part Belonging to a man. O, be some other name! What's in a name? That which we call a rose By any other name would smell as sweet; So Romeo would, were he not Romeo call'd, Retain that dear perfection which he owes Without that title. Romeo, doff thy name And for that name which is no part of thee Take all myself.  Shakespeare – Romeo and Juliet Act II, Scene 2 We normally only use the bold portion of the famous Shakespearean quote above, but it is really out of context. As the play unfolds, we learn that a name is all too powerful. Indeed it is because of their names that the doomed lovers die. There might be life and death in a name (BTW, when I wrote this monogram, I was in Hatfield, PA. Remember the Hatfields and the McCoys?) This is a bit extreme, but in the field of Knowledge Management (KM) names are of the utmost importance as well. When I write an article about managing SharePoint sites, how should I name it? “Managing a site” or “Site, managing”? Nine times out of ten I’d opt for the latter. Almost everything we do is “Managing” so to make life easier for a person looking for meaningful content, we title our articles starting with the differentiator rather than the common factor. As a rule of thumb, we start the name with the noun rather than the verb. It is not what we do that is the primary key; it is what we do it to. So, answer this – is it a “rule of thumb” or a “thumb rule?” This is tough. A lot of what we do when naming is a judgment call. Both thumb and rule are nouns, albeit concrete and abstract (more about this later), but to most people “thumb rule” is meaningless while “rule of thumb” is an idiom. The difference between knowledge and information is that knowledge is meaningful information placed in context. Thus I elect the “rule of thumb”. It is the more meaningful title. Abstract and Concrete are relative terms. Many nouns (and verbs) that are abstract to a commoner, are concrete to a practitioner of one profession or another and may even have different concrete meanings in different professional jargons. Think about “running”. To an executive it means running a business, to a marathoner its meaning is much more literal. Generally speaking, we store and disseminate knowledge within a practice more than we do it in general. Even dictionaries encyclopedias define terms as they apply to different audiences. The rule of thumb is to put the more concrete first, but within the audience’s jargon. Even the title of this monogram is a question. Do I name it “Naming Documents” or “Documents, Naming”? Well, my own rule of thumb (“Here he goes again!?”) states that the latter is better because it starts with a noun, but this is a document about naming more than it about documents. The rules of naming also apply to graphs and charts, excel spreadsheets, and so on. Thus, I vote for the former.  A better title could have been “Naming Objects” only the word “Object” is a bit too abstract. How about just “Naming” or “Naming, rules of”? You get the drift. One of the ways to resolve all of this is to store the documents in Knowledge-Bases, which may become the subjects of a future punditry. Knowledge bases use keywords to describe their content.  Use a Metadata store for the keywords to at least attempt some common grounds. Here is another general rule (rule of thumb?!!) – put at least the one keyword in the title. Use subtitles. Here is an example: Migrating documents – Screening, cleaning, and organizing our knowledge. The main keyword is “documents”, next is “migrating”, other keywords also appear in the subtitle. They are “screening”, “cleaning”, and “organizing”. Any questions? Send me an amply named document by email: [email protected]
