• Splitting Logic, Data, Layout and "Hacks"

  - by fjdumont

  Sure, we all heard of programming patterns such as MVVM, MVC and such. But that isn't really what I'm looking into as Layout, Data and Logic is already pretty much split up (XML-Layout markup, Database, insert your language of choice here). The platform I am developing for is hard to maintain over the updated versions and older OSes. The project significantly grew up over the last few months and dealing with different platform versions really is a pain. For example simply disabling an user interface control for all existing versions took me around 40 lines of code in the logic layer, wrangling around with invocation, delegation, singletons that provide UI handling and so on. Is there a clean way to keep track of those "hacks" by maybe excluding it into separate classes or even packages? Should I overwrite existing framework code in order to handle my requirements correctly? If so, does that concept have a name?

• How to calibrate Toshiba LED screen - the colours are over saturated

  - by user94369

  I have purchased a new Toshiba Satellite C850-A812 laptop, with ATI Radeon HD 75xx series. When i first installed Ubuntu 12.04.1, the open source driver worked like a charm with the colors, i mean the colors were so vivid. However after installing the ATI proprietary driver from the repos, the colors went too "whity" and too bright. I even installed the updated driver, and went further to download the latest driver from ATI and install it in vain. I tried to use the ubuntu build in calibration tool, but it keeps on asking me to enter the ICC profile before i proceed to calibrate. I played with the catalyst control center, tried everything possible, but still the colors are still wayyyyyyyyy over exposed. Please advice :)

• atheros wireless ar9285 driver

  - by nikola

  I have been having problems with wireless on Ubuntu 10 and above, Mint 11 and above. The problem is in the driver for the wireless... I can see that there is no driver installed and yet it works but reduced a lot, for example: on windows 7 ultimate 100% on distance of 1 meter (currently running) Mint Cinnamon 15 on same distance 70% when it goes under the 40 % it simply disconnects and than takes a lot of time to connect again I am new to Linux and I don't know anything about programming, yet I love the interface and look of the OS but don't want to reject it for couple of problems. There is, however, a problem with brightness control on laptop, it shows the notification and slider but with no effect The question is: Can somebody explain to me where to download and how to install the ar9285 driver for atheros wireless card laptop acer emachines eme529? or can someone explain this to me only for the LINUX MINT 15 http://www.jrhenkelmann.net/index.php?option=com_content&task=view&id=34 because the synaptic's interface is different than of mint 15 I KNOW this is Ubuntu community but the problems persist in all Linux versions

• How to re-enable tray icons for applications in ubuntu 13.10?

  - by andraaska

  Unfortunately in new Ubuntu 13.10 there is no Tray Icon and Whiteliting is removed. The older solutions are not works for me, e.g.: No such schema 'com.canonical.Unity.Panel' message answered when I try to use the gsettings set com.canonical.Unity.Panel systray-whitelist "['all']" comand. How can I get tray icons back (for applications that put icon in tray like Truecrypt, Pidgin, Aqualung, gnome-system-monitor, gyache, and so many more...) in Unity ? The most annoying is that the user loses control over applications can not detect itself that it has no tray icon... (e.g.: gnome-system-monitor, truecrypt...) At least Aqalung send a message about unable to put icon on systray! Thanks

• When and How is an image cached for an ASPX with ContentType = image/jpeg ?

  - by Aamir Hasan

   In asp.net you can cache your page. You can vary the output cache by the followingThe query string in an initial request (HTTP GET).Control values passed on postback (HTTP POST values).The HTTP headers passed with a request.The major version number of the browser making the request.      A custom string in the page. In that case, you create custom code in the Global.asax file to specify the page's caching behavior.Link: http://msdn2.microsoft.com/en-us/library/xadzbzd6(VS.80).aspxyou can set the output caching for your GetImage.aspx, so that you dont have to requery the database every image request ,but you must use varybyParam , so that you have a cached version for every parameters arrangement:set the output cache for your page like this :At top of ASPX page: <%@ OutputCache Duration="600" VaryByParam="ID,Height,Width" %>VaryByParam  attribute allows you to vary the cached output depending on the query string.Adding this will make your images cached for 600 seconds, so that if the image request within this period ,the cahed version will be returned

• Template standard controls for an entirely new look and feel

  - by T

  This is the  Ineta Live player without the O’Data Feed.  It is a good example of taking the plain Media Player provided with the Encoder install and re-templating it to make it your own.  It also has a custom scrub control that is added in.  I generally put my tempates in a separate resource file.  On this project, I discovered that I had to include the template at the document level because I needed the ability to attach some code behind to fire change state behaviors.  I could not use the blend xaml behaviors for change state inside the template because the template can’ determine the TargetObject.   Version 1.01 – 6/10/09 (wow how did a week slip by)

• Two "subdomains" crossing search results

  - by LuckySpoon

  My question relates to two websites, each of which is a "Calvary Christian College", however in two totally different locations and unrelated to each other entirely (except by name, and domain). All schools in the state are issued a .qld.edu.au, in this case calvary.qld.edu.au and calvarycc.qld.edu.au. Now what's interesting is that these domains are crossing each other in sitelinks for searches such as "calvary christian college townsville" (if you check the sitelinks 2/6 are to a different domain). I've put a demotion in for this ages ago (we control calvary.qld.edu.au), however we're seeing no change on the results page. I have been able to get the owners of calvarycc.qld.edu.au to submit demotions for our domain, which should go in sometime this week. What can we do to tell Google that these websites are not interchangeable, despite both appearing as "subdomains" of qld.edu.au. We can possibly open channels of communication with the administrators of qld.edu.au but will need to tell them what we need to change, and at this point I'm out of ideas.

• SEO: Joomla Category Page Optimization + Canonical Linking

  - by Huberis

  I'm wondering how best to optimize my Joomla site's SEO. I have pages with multiple articles on each page. Either via category-type pages, or via modules. In each case, I'm not wanting users to access the articles separately from the forward facing, menu-linked pages. I understand however that Joomla still generates a url for those articles, and Google can still crawl and display these articles separate from the pages. My question is what is the best way to control this so that my users get directed only to the front-facing pages? By using the canonical element for each article to point to the front-facing page it's on? Or is there a better method? Thanks for your help!

• Windows 7/ 12.04 Dual Boot Mess

  - by Ben

  I am certainly new to ubuntu (linux in general)... I added ubuntu 12.04 as a dual boot to a brand new desktop which had win 7 pre-installed. Both work well Then I tried to change the order of the boot menu to make Ubuntu first and Win7 second... I did this from the windows side (it seems that my setup is relying on windows bootloader, which I don't think I need to change) using the built-in startup manager (I think that's what windows calls it- it's in the control panel). I set Ubuntu as first (default if no user input). then... I ACCIDENTALLY ("hmmm...I wonder what this button does?") set the menu timeout to "0" Now, I cannot change the menu timeout (because I cannot get into windows) and without doing so, I cannot select windows as the OS I would like to boot(I cannot get into windows). Any Ideas?

• Silverlight 4 + RIA Services - Ready for Business: Authentication and Personalization

  To continue our series,  In real business applications our data is often very valuable and as such we need to know who is accessing what data and control certain data access to only users with privilege.  Luckily this is very easy to do with RIA Services.  For example, say we want to let only authenticated users access our data in this example.   That is as easy to accomplish as adding an attribute, see line 2 below.    1: [EnableClientAccess] 2: ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• When to learn the command line version of a programming tool ?

  - by explorest

  Almost every programming tool has a command line version; many of which also have a gui version. It takes a lot of time and memorization effort to learn the different commands and various options/switches om the command line version. So I have a couple of questions (which are not necessarily mutually exclusive): 1) When would you bother learning/memorizing the commands in the command line version of a tool which also comes in a gui version ? 2) What tools should I learn the command line version of ? .... compilers ? version control system ? etc, etc

• Oracle Service Contracts – Calculate Estimated Tax with Higher Accuracy

  - by LuciaC-Oracle

  On a Service Contract the tax rate and its effectivity can change over the contract duration.  Hence, service organizations need to provide an accurate picture of the estimated tax that the customer might end up paying.  Prior to Release 12.1.3+, the Oracle Service Contracts application calculated the estimated tax based on the line/ sub line start date.  With Release 12.1.3+ (via Patch 16601269:R12.OKS.B) , new functionality provides users with an option to calculate tax at contract billing schedule level, thereby considering the changes in tax rate effectivity at that level.A new profile option 'OKS: Calculate Tax at Schedule' has been introduced which can be used to control whether the existing or new functionality is used.  If the profile is set to 'Yes' the application calculates tax at the billing schedule level for all lines/ sub lines.  For more details on the implementation steps and functionality, please refer to Doc ID 1676700.1: Oracle Service Contracts – How To Calculate Estimated Tax with Higher Accuracy.

• Can you be a programmer and Business manager at the same time?

  - by the_knight5000

  Hello all, I think I'm struggled in some situation! We are a new start-up with 5 employees (2 Programmers). I'm the Technical Manager and that was so fine! Now I can see the fingers point to me to take the control of everything, as I've the big vision of what our organization do and play the role of CEO or General Manager! I want to, but I've no idea if it would be risky to our organization to make such a decision? How would managerial interrupts affect the technical productivity? Any tips or previous experience about such situation would help :) Thanks in advance!

• Is there any way to simulate a slow connection between my server and an iPad (without installing anything on the server)?

  - by Clay Nichols

  Some of our webapp users have difficulty on slower connections. I"m trying to get a better idea of what that "speed barrier is" so I'd like to be able to test a variety of connection speeds. I've found ways to do this on Windows but no on the iPad, so I'm looking more for some sort of proxy service that'll work with any device (not running ON that device) I did find an article about using the CharlesProxy and providing a connection to another device, but I was hoping for something simpler (need not be free) Constraints * We are on a shared server so we can't install anything and we are limited in our control over that server. * I'd like to test an iPad, Android Tablet, Windows PC.

• TFS 2010 and Expanding Possibilities

  - by ssmantha

  My organization is migrating to the new Team Foundation Server 2010, and we all are busy experimenting with ALM features. I find it very exciting and I foresee quite a lot of possibilities for TFS 2010 getting integrated with the Dynamics product line. I hope most of us know about the Version Control capabilities. However, I see a strong possibilities of having Team Builds and other automations, thanks to the technologies like workflow foundation in .net which is now being actively used in various TFS scenarios.   Lots of experiments so there is more to come!!

• What issues are there for doing freelance work?

  - by Telos

  I'm considering doing some contract work on the side of my normal job. I know that it will kill my free time, but I figure I can control when I'm doing projects and then get a little extra money or even eventually make it my full time job. But as I've never done this before, I'm wondering what issues people face to do this kind of work. For instance: how do you find customers? What difficulties do you normally face on a project? How do you deal with projects that are too large for one programmer to effectively complete? What about projects that need other skill sets (for instance web design for a web app?)

• I try install dhcp3-server, but /etc/init.d/dhcp3-server file is missing. Whats going on?

  - by hydroparadise

  I've found several how-to's that essentially go through the same process in setting up DHCP. Here's a link that has the list of step needed install and setup DHCP. I follow all the steps and find that the sudo /etc/init.d/dhcp3-server restart portion returns command not found only to reveal the the file doesn't even exist. I've installed (sudo apt-get install dhcp3-server) and uninstalled (sudo apt-get remove dhcp3-server) two or three times. I'm pretty sure my config files are good because I've had to check them three times. But I don't think I'm to that point of being able to see them action it. I cant control the process. Why is the file missing? How is it supposed to get there? Help?

• Empathy authentication error to XMPP server

  - by Shauna

  I recently installed Ubuntu 12.04 on a new machine and have been working on setting it up, but I've run into an interesting problem. I have a custom XMPP server for work (I don't control it, but we're using an in-house install). I can connect to it just fine via Pidgin, but due to some UI issues I'm having with Pidgin (and what appears to be better overall integration between Empathy and Ubuntu/Unity), I'd like to use Empathy instead. However, Empathy won't connect to my XMPP server, and I keep getting an authentication error and repeatedly prompted for my password. This happens even when importing the working account information from Pidgin (so I know things like the password are correct). Is there a way I can get Empathy working with my XMPP server?

• What "version naming convention" do you use?

  - by rjstelling

  Are different version naming conventions suited to different projects? What do you use and why? Personally, I prefer a build number in hexadecimal (e.g 11BCF), this should be incremented very regularly. And then for customers a simple 3 digit version number, i.e. 1.1.3. 1.2.3 (11BCF) <- Build number, should correspond with a revision in source control ^ ^ ^ | | | | | +--- Minor bugs, spelling mistakes, etc. | +----- Minor features, major bug fixes, etc. +------- Major version, UX changes, file format changes, etc.

• Adding PPA on install

  - by trampster

  I have a app I am packaging for ubuntu. I don't like the idea that if included in the ubuntu repositories I will have no control over updating that application. I don't want my users stuck on an out dated version for up to 6 months. I also do not want my users to have to manually add a PPA themselves to get updates as the target user will not have the technical know how to do this. Is it OK to have my .deb add a PPA on install. So that I can roll out stable updates to my ubuntu users.
