• Algorithm for Learning development

  - by user9057

  Hi all, This is a fairly general question. I know a bit of Perl and Python and I am looking to learn programming in more depth so that once I get the hang of it I can start developing applications and then websites. I would like to know of an algorithm (sequence of steps :)) that could describe my approach towards learning programming in general. I have posted small questions on Perl/Python and I have recieved great help from everyone. Note:- I am not in a hurry to learn. I know it takes time and that's fine. Please give any suggestions you think are valid. Also, please don't push me to learn Lisp, Haskell etc - I am a beginner.

  - by user292125

  I have recently installed Ubuntu 14.04 LTS on my system. But the usb port does not seem to be working.

• Create .exe and .msi Installers for your JavaFX Apps

  - by mikew_co

  Well I wanted to figure out how the new JavaFX native packaging worked, so with a little work, I have written up my findings. Create a Windows Native Installer and EXE with JavaFX and NetBeans 7.2All the information is in the articles I have linked to at the end of the page. However, I hopefully have pulled together all the key facts in one place. In addition, I tried to document all the problems I ran into in the troubleshooting section. So what is the end result?  With everything installed, building an application in NetBeans creates an EXE installer, an MSI installer, and an EXE file to execute your application. Really slick professional stuff. This is a great addition to the whole Java platform.

• Website custom tracking

  - by Francisco Goldenstein

  I'm using ASP.NET MVC 4 and I want to track the incoming traffic of my site to know things like: 1) How many users that clicked a Google Adwords advertisement have bought one particular product? 2) Ranking of buyers grouped by Google Adwords advertisements. I could add a parameter to the URL like mysite.com?source=advertisement1234 but I want to avoid this practice to have cleaner URLs and for SEO purposes. Url.Referrer is not going to give me that information either, it's just going to say that the referrer is Google. Any suggestions? Thanks in advance!

• TechEd 2014 Day 4

  - by John Paul Cook

  Many people visiting the SQL Server booth wanted to know how to improve performance. With so much attention being given to COLUMNSTORE and in-memory tables and stored procedures, it is easy to overlook how important tempdb is to performance. Speeding up tempdb I/O improves performance. The best way to do this is to not do the I/O in the first place. With SQL Server 2014, tempdb page management is smarter. Pages are more likely to be released before being unnecessarily flushed to disk. Read more about...(read more)

• Android design advice - services & broadcast receivers

  - by basudz

  I'm in the process of learning the Android SDK and creating some projects to get a grasp on the system. The current project I'm working with works just fine but I'd like to get some advice about other ways I can go about designing it. Here's what it needs to do. When a text message is received from a specific number, it should fire off a toast message that repeats at a certain interval for a specific duration. To make this work, I created an SMS BroadcastReceiver and checked the incoming messages for the number I'm looking for. If found, an IntentService would be started that would pull out the interval and duration from saved shared prefs. The IntentService would then fire off a broadcast. The BroadcastReceiver for this would catch it and use the AlarmManager to handle the toast message repetitions. This all works just fine, but I'm wondering if there's a cleaner or more efficient way of going about doing this? Any suggestions or advice?

• Anti-depressant and programming

  - by user12358

  I wanted to ask your opinion on anti-depressants, since I took them daily for 3 years now, but I can't be sure if I'm less perfomant with them or without, since I never withdrawed. I'm still at school at the age of 25, still having some motivation problems (for example I can't get used to do something at school if I don't think it will teach me something), but I'm quite motivated to work in the video-game field, since I have some personnal projects in mind. I know C++ programming etc, I'm still learning techniques, but do you think I should try more to do my project instead of just following the work I'm assigned to ? Have you had experience with depression or anti-depressants ? How did it affect your work ? Do you think that being depressed or half-depressed can improve creativity ?

• Universal Work Queue Quick Filter Examples

  - by LuciaC-Oracle

  If you use Universal Work Queue then it's likely that you will want to define and use your own Quick Filters.  Quick Filters allow you to focus on specific work classes based on assigned criteria in a node. This makes it much easier for Agents to view their work grouped in a meaningful way.How to create Universal Work Queue - Quick Filters (Doc ID 803163.1) gives two worked examples to help you understand how to create your own Quick Filters:     Adding a 'Resource Group' filter     Adding an Overdue Amounts filter for use in Collections. We hope you find these examples useful.  Let us know by providing feedback on the document itself or, why not post to the MOS Service Community with your experience and suggestions.

• Changing location after CommitAnimations

  - by Will Youmans

  I'm using the following code to move a UIImageView: shootImg.image = [UIImage imageNamed:@"Projectile Left 1.png"]; [UIView beginAnimations:nil context:nil]; shootImg.center = CGPointMake(shootImg.center.x+1000, shootImg.center.y); [UIView commitAnimations]; This works but what I want to do is after [UIView CommitAnimations]; I want to set the location of shootImg using CGPointMake. If I just put it after commitAnimations then the animation doesn't fully complete. Any suggestions? I'm not using any frameworks like cocos2d and if you need to see any more code just ask.

• How do I replace Unity?

  - by Krista O'Connors

  I wanted to use Ubuntu 12.04 for its long term support. But I cannot stand Unity. I cannot find a way to replace it with compizconfig, so I tried replacing it with Lubuntu. When I restarted my computer started to load lubuntu, then just went right on with ubuntu as if nothing had happened. Likewise, it shows lubuntu when it shuts down. What is the deal? I'm confused here, is ubuntu 12.04 supposed to be an operating system or a desktop interface? Can I even run ubuntu with a Lubuntu interface? Is there a way to do this in compizconfig that I should be doing instead?

• Dell L501X Display Port Screen issue

  - by jdflorezPA

  I got a Dell XPS L501X with a mini display port to VGA connector for my External Screen. On Displays it shows me: Acer Technologies 24" (which is the monitor) but only lets me up to 1024x768 resolution (The native resolution of this monitor is 1920x1200). I tried adding a new mode with xrandr, but when I applied it, it reverted back to 1024x768. As far as I know, the display port is controlled by the Intel card, right? Any ideas or suggestions would be appreciated. Thanks Using Ubuntu 11.10 32bit

• Black screen on Ubuntu 12.04

  - by user1648371

  I've just upgraded to Ubuntu 12.04 and I'm experiencing some problems. The first thing I noticed is that when I click the Workspace switcher all I get is a black screen (I can guess where the different workspaces are located and clicked on them, not a practical solution though). In addition when I lock the screen or suspend the laptop (a Vaio VPCEB4M1E) I get a shifted screen (I see the right most vertical stripe on the left size of the monitor and nothing about all the rest, to put it clearly I can see the gear that allows me to turn the pc off, etc, but not much more..) when I go to the additional driver menu I see the "ATI/AMD proprietary FGLRX graphics driver" are installed and the post-release update version is available. I don't know if the problem is driver related, so before doing anything I'd like to get some suggestions from you guys. Thanks you!

• Why CoffeeScript is an issue

  - by Renso

  Other than some obvious concerns, my main concern is support in the open source community. "anon" from the CoffeeScript team sent this to me after I requested input from the team to concerns I raised and wanted to get others' take on it:"Thanks for confirming that only idiots willingly program in Java and C#"or the following from the same person:"Oh and finally, you should definitely create jShort. Even though I know you will fail before you even start, I would love to laugh at your attempts and it would be perfect for you since you ride the short bus. "This kind of comment reflects badly on the CoffeeScript team and hence not an option for us as a company to consider. Another example of why some open-source community projects get no traction.

• Can't boot - "Waiting for Network Configuration"

  - by user213017

  After an update on 13.10, my PC won't boot Ubuntu any longer. It displays the infamous "Waiting for Network Configuration" message and then hangs. I can go into recovery mode, and choose "Start networking" and then go to a root prompt, and that works fine. Ping works. /etc/network/interfaces contains just the two lines "auto lo" and "iface lo inet loopback". I've double-checked that my network is working, the cable is working (it works on another PC) and the network card seems to indicate a connection. Any suggestions on how to get my PC booted again? Right now I'm limited to a root shell prompt.

• Knockback enemy based off of direction sprite is facing

  - by pengume

  Hey Everyone, Today I am trying to make it so if I hit the enemy then the enemy well be knocked backwards in the direction the sprite is facing. I am rotating the sprite around 360 degrees using a joystick on the screen and wanted to know the best practice or ways to accomplish this. I have come up with a few ideas but none of them make use of the sprites angle he is facing just a check to see if I hit the bottom then move him upward and so forth. I am just stumped on how to apply the sprites angle to the enemies x and y coordinate and move him accordingly. Has anyone tried this and have suggestions or things to look for? Thanks in advance.

• Develop for Desktop and Mobile at once

  - by Hola Soy Edu Feliz Navidad

  I need to develop a programm that is going to read some information from a special USB device and access information via Web Socket (socket.io preferred). My client wants to deploy this app on Mac OS X, Windows, Android and iOS. I was looking for development softwares valid for both: Desktop and Mobile, but it is still not clear for me and that´s what I found. Unity - Looks very good but to create a native plugin for reading from the device it lloks like I need the PRO edition. Adobe Air - Looks good but I´m not sure if I can write Native Plugins for all wanted platforms. LiveCode - Still inmature (lots of bugs) and I don´t know if it is possible to write native plugins for my device. Is there any other good platform for my case? What´s your option?

• Tagging Objects in the AppFabric Cache

  In two of my previous entries I outlined functionality and patterns used in the AppFabric Cache.  In this entry I wanted to expand and look at another area of functionality that people have come to expect when working with cache technology.  This expectation is the ability to tag content with more information than just the key.  As you start to examine this expectation you will soon find yourself asking if the tagged data can be related to each other and finally if it is possible...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Internet Not Working... Initially Worked fine

  - by Sneha429

  I am using an HP Pavilion desktop, not sure of exact model, etc. Initially saucy looked and worked great. It's my parents, and after two days of no issues, they started having more than a few. The mostly use the internet to access email and videos. I believe Google Chrome was the only application they used. Then, the internet stopped working. Restarting didn't fix it, neither did turning the internet on and off. The computer went from lightening fast to inexplicably slow. I've read some other posts about the internet not working, but none seemed applicable. Any suggestions?

• What are the Search engine affects of registering the same domain on multiple top level domains (ie. .com, .ie, .nl etc.)?

  - by user1020317

  I'm looking to register a few more domains for my company, I have my-company.com at the moment, but now require my-company.com.au and my-company.nl and some others.. I'm running through my options and wondering what is the best.. Duplicate all the content on the .com package and make a replica at the other domains Buy the other domains but do a 301 redirect back to the .com domain. Create a full new website with different content for the new domains, thus having no text duplication We currently sell over the world so would like to raise our Search rankings in various countries, can this be done by buying the domain in the country, and if so, how will the above methods affect our search rankings. Any other suggestions are welcome!

• Cannot load a webpage with hp pavilion dv2000 laptop

  - by Andre'

  I am using an Ubuntu 12.04 cd to test out the os before I take the plunge, and I can't get webpages to load in the firefox application. When I look at the wireless settings, ubuntu says that my computer is connected to my home wireless network, but I am repeatedly prompted to enter my password (it keeps telling me that authentication is required by my wireless network). After a few rounds of this, Ubuntu seems to give up and tells me that wireless network is disconnected. Furthermore (I'm currently in ubuntu using a wired connection if it has anything to do with this), the wireless connection will randomly attempt to establish itself. I've entered rfkill list and all of the wireless devices therein say "no" - they're not blocked. I can connect to the network in Windows 7, so I don't think my network is the problem. Any suggestions?
