• Understanding Data Binding for Windows Phone 7

  - by nikhil

  I want to develop a simple app for the Windows Phone 7 platform. It's basically a vocabulary based game that involves the user moving word tiles from one area to another to score points. I want to know what is the best way of tying the UI to the game's backend? I saw the Windows Phone 7 jumpstart videos, there they touch up on Data Binding but don't really go into any depth. I'm a newbie and don't have any experience with designing the architecture for a phone app, It'd be great if someone could explain what steps I should be taking or guide me to a resource from where I could learn more.

• Who was your mentor? Where can I find mine?

  - by aredkid

  In many of articles I've read, finding a mentor is often suggested. One to who would guide, teach and more. (I wouldn't know the details, I don't have one, yet.) So, who was your mentor, if any? I have only had indirect mentors: professor at university, manager at work whom I've watched and learnt from the most. And otherwise, Twitter has been a great place to follow the professionals and discover more about the technologies that interest me. But I still wonder how I could find one because I can sense that I might be lacking in my experience. Ideas?

• Installing software on an offline Ubuntu server

  - by Muhammad Gelbana

  Assuming that I have a server with Ubuntu server newly installed on it. I was thinking of installing the very same version on Virtual Box (Or any other virtualization software), connect it to the internet and use apt-get to only download the packages for upgrading the system and the new software such as (tomcat7, openjdk6-default-headless..etc). Then copy the downloaded packages from the archive folder to the offline server's archive folder through a USB stick. So now the virtual system won't actually be upgraded nor have any new software installed. But would running the very same apt-get commands on the offline system without the download directive -d be executed without issues ? *EDIT:*This needs to be as simple as possible because I'll have to write a guide for our client to do this on his own and so it won't be acceptable to require deep Linux knowledge to do this.

• Python Imaging: YCbCr problems

  - by daver

  Hi, I'm doing some image processing in Python using PIL, I need to extract the luminance layer from a series of images, and do some processing on that using numpy, then put the edited luminance layer back into the image and save it. The problem is, I can't seem to get any meaningful representation of my Image in a YCbCr format, or at least I don't understand what PIL is giving me in YCbCr. PIL documentation claims YCbCr format gives three channels, but when I grab the data out of the image using np.asarray, I get 4 channels. Ok, so I figure one must be alpha. Here is some code I'm using to test this process: import Image as im import numpy as np pengIm = im.open("Data\\Test\\Penguins.bmp") yIm = pengIm.convert("YCbCr") testIm = np.asarray(yIm) grey = testIm[:,:,0] grey = grey.astype('uint8') greyIm = im.fromarray(grey, "L") greyIm.save("Data\\Test\\grey.bmp") I'm expecting a greyscale version of my image, but what I get is this jumbled up mess: http://i.imgur.com/zlhIh.png Can anybody explain to me where I'm going wrong? The same code in matlab works exactly as I expect.

• What is the best way to pass data into an API from a website?

  - by Chris Wakoksi

  My main objective is to create a User Interface in order to provision(change the status: activate, deactivate, or suspend) modems. I have received a SOAP developer's guide to the specific type of modem that helps out with the specific values that I need to pass into Iridium's WSDL but I cannot figure out how to do this from a webpage I have created using HTML/CSS, and PHP? I have been told by others that I need to know the portal. I have no idea what that means. I am a beginner programmer who has learned programming for this project. Any suggestions as to how to pass my data into the provisioning API?

• What is testable code?

  - by Michael Freidgeim

  We are improving quality of code and trying to develop more unit tests. The question that developers asked  was  "How to make code testable ?"  From http://openmymind.net/2010/8/17/Write-testable-code-even-if-you-dont-write-tests/ First and foremost, its loosely coupled, taking advantage of dependency injection (and auto-wiring), composition and interface-programming. Testable code is also readable - meaning it leverages single responsibility principle and Liskov substitution principle.A few practical suggestions are listed in http://misko.hevery.com/code-reviewers-guide/More recommendations are in http://googletesting.blogspot.com/2008/08/by-miko-hevery-so-you-decided-to.htmlIt is slightly too theoretical - " the trick is translating these abstract concepts into concrete decisions in your code."

• Ubuntu 12.04 freezes on suspend hp folio 13

  - by Tom O'Brien

  I have ubuntu 12.04 running from a usb HDD on my hp folio 13. Everything is working, but at first the screen would only blacken when i closed the lid and didn't suspend. So, I followed this guide: https://github.com/deliciousrobots/ubuntu-hp-folio-13 after that, it sort of worked, but very unreliably. Now suspend doesn't even work and it always freeze. Usually the screen will turn black but I can still see my mouse. Sometimes my desktop background will show but the launcher wont be there or anything. Once I didn't have the menu bar on any windows or the top of the screen but the windows I had left open were still (sort of) responsive. Whats wrong? Help Thanks

• xmonad keyboard doesn't work

  - by Mikkel Paulson

  I'm experimenting with xmonad, which I installed from the Ubuntu Software Centre on Ubuntu 12.10. It looks cool, but when I invoke it (using xmonad --replace from the command line) my title bars disappear and my keyboard stops working. At all. The terminal stops working, the keystrokes I've seen in online "getting started" guides are ignored, and the only way for me to actually power the system off is to hit the reset button or ssh in from my phone. Ironically, my mouse still works. One guide I saw suggested replacing the default window environment with xmonad, but I'm afraid of rendering my system completely inoperable if I do that. Any suggestions?

  I've configured gnome-file-share-properties on all my Ubuntu's PC for sharing the directory Public to each other. I following some guide found on Internet for the configuration of it, all explain the same procedure but in my case I don't see any Public directory shared with the PC.

In my case I don't see anything, therefore on the Network place see all the machines 'n if I try to click on one receive this: "DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)" note: I don't want to use Samba because I've all Ubuntu PC, and the firewall is disabled on all PC.

• How URL Redirection affects SEO?

  - by Costa

  The following paragraph is from SEO Google Guide Google is good at crawling all types of URL structures, even if they're quite complex, but spending the time to make your URLs as simple as possible for both users and search engines can help. Some webmasters try to achieve this by rewriting their dynamic URLs to static ones; while Google is fine with this, we'd like to note that this is an advanced procedure and if done incorrectly, could cause crawling issues with your site. What makes URL re-writing implementation incorrect for GoogleBot? I am using Asp.net 3.5 framework. Thanks

• Framework Folders and Duplicate File Names

  - by Kevin Smith

  I have been working with Framework folders a little bit in the past few days and found one unexpected behavior that is different from Contribution Folders (Folders_g). If you try and check a file into a Framework Folder that already exists in the folder it will allow it and rename the file for you. In Folders_g this would have generated an error and prevented you from checking in the file. A quick check of the Framework Folder configuration settings in the Application Administrator’s Guide for Content Server does not show a configuration parameter to control this. I'm still thinking about this and not sure if I like this new behavior or not. I guess from a user perspective this more closely aligns Framework Folders to how Windows handle duplicate file names, but if you are migrating from Folders_g and expect a duplicate file name to be rejected, this might cause you some problems.

• Create Out-Of-Process COM in C#/.Net ?

  - by Huck

  Hi, I need to create an out-of-process COM server (.exe) in C# that will be accessed by multiple other processes on the same box. The component has to be a single process because it will cache the information it provides to its consumers in memory. Note: the processes that will access my COM Server are mostly Matlab processes, thus the necessity for a COM interface. I have seen threads regarding creating in-process COM components in .Net on stack overflow (Create COM ...) and on the web, but am having a hard time to find a way to create out-of-process components with .Net. How is this achievable? Any suggested references? Thanks.

• Website Stopped Showing From Google Search Results Sunddenly

  - by Aman Virk

  I have a design and development blog http://www.thetutlage.com (1.5 years old), which was doing really well in Google search as I was getting over 70% of my traffic from Google. Now suddenly from last two days it reduced the amount of traffic from 70% to 20% and also when I am trying to search for the exact posts that I can created even after appending my website name to it does not show any results for that. Sample Search Text: JQuery Game Programming Creating A Ping Pong Game Part 1 I have post with exact same title and it does not show it on Google search anywhere. I am totally shocked, I write my own unique content and follow Google guide lines like bible. Also there is no message under my webmasters account stating any problem or error.
