• Xamarin Wins Funding, Microsoft Builds Repair Tool

  Let's focus on the Xamarin news first. Xamarin is a young company with a phoenix-like history. Founded in May of 2011 by Miguel de Icaza and the rest of the team that created Mono, Xamarin got its start, effectively, as Ximian (de Icaza's previous company). Ximian was founded way back in 1999, and created Mono, which TechCrunch describes as an open source project that brings Microsoft's .NET development framework to non-Microsoft operating systems like Android, iOS and Linux. Novell acquired Ximian inn 2003, and continued to fund Mono's development. But apparently, when Attachmate bought No...

• OpenGL Vertex Attributes - Normalisation

  - by Daniel

  Alas, I have searched, and have found no definitive answer. When would you normalize the vertex data in OpenGL using the following command: glVertexAttribPointer(index, size, type, normalize, stride, pointer); I.e when would normalize == GL_TRUE; what situations, and why would you choose to let the GPU do the calculations instead of preprocessing it? All examples I have ever seen, have this set to GL_FALSE; and I cannot personally see a use for it. But Khronos aren't stupid, so it must be there for something useful (and probably common).

• Vector.Unproject - Checking if a model intersects a large sprite

  - by Fibericon

  Let's say I have a sprite, drawn like this: spriteBatch.Draw(levelCannons[i].texture, levelCannons[i].position, null, alpha, levelCannons[i].rotation, Vector2.Zero, scale, SpriteEffects.None, 0); Picture levelCannon as being a laser beam that goes across the entire screen. I need to see if my 3d model intersects with the screen space inhabited by the sprite. I managed to dig up Vector.Unproject, but that seems to only be useful when dealing with a single point in 2d space, rather than an area. What can I do in my case?

• Hosting advice for a write-heavy dynamic website

  - by Rahul Rawat

  I have built a website using PHP and MySQL and now I am looking for a hosting service. I am expecting about a 1000 users registering and about 5-10k pageviews/day in a week's time. So which host should I opt for? It will let users submit contents of type blobs and submit around 10 pictures per users. I hope that traffic will increase so can justhost's or bluehost's shared hosting serve that purpose or should I go for more dedicated ones. Basically the site is write heavy and there are average 2-3 MySQL queries per page and it is quite dynamic. So depending on these requirements which web hosting will be optimal for me.

• Mercurial release management. Rejecting changes that fail testing

  - by MYou

  Researching distributed source control management (specifically mercurial). My question is more or less what is the best practice for rejecting entire sets of code that fail testing? Example: A team is working on a hello world program. They have testers and a scheduled release coming up with specific features planned. Upcoming Release: Add feature A Add feature B Add feature C So, the developers make their clones for their features, do the work and merge them into a QA repo for the testers to scrutinize. Let's say the testers report back that "Feature B is incomplete and in fact dangerous", and they would like to retest A and C. End example. What's the best way to do all this so that feature B can easily be removed and you end up with a new repo that contains only feature A and C merged together? Recreate the test repo? Back out B? Other magic?

• wired connection not being recognised in ubuntu 10.04 lts

  - by arun

  I have windows7 installed on my C drive and ubuntu 10.04 lts on my D drive. When I plud the lan cable (ethernet cable) onto the ethernet card of my laptop, windows7 identifies the network correctly without the need for any manual settings and connects me to the network correctly. Unfortunately, in ubuntu, even after plugging in the cable, nothing happens (on the network side). It is only scanning for wireless networks it seems, and doesnt bother about the wired networks. I tried adding a new wired connection and manually entered the physical address which was displayed when i connected to the network using windows. i entered the phy address, and told it to use auto dhcp and saved the dialog bog in ubuntu network connection. Still there is no change, and ubuntu doesnt seem to recognise anything. please let me know how to work with wired connections using ubuntu, and why my wired cable is not being recognized in ubuntu. thanks. PS: I am pretty new to ubuntu/ linux :)

• User prompts (MessageBox) with MVVM

  - by mukapu

  The problem statement: I am tired of thinking how to show a simple message box or user prompt and act based on the response in Model-View-View-Model (MVVM). Common approaches: - It's ok, let's just do this one thing from ViewModel and mock this out for unit testing - Design my own dialog, then what to do from there - Can I write something in view code behind, ah yes, that seems to be the only way out, as anyway MVVM is still not matured...  - and what not?   I am pretty much one among the few frustrated out in this world looking for some convincing answers. I think we can do it a little neater without having the feeling of violating any of our self defined rules! Solution: The Control - Implement a simple control with no designer visibility. - Allow a property to be bound to tell when to show the MessageBox - Provide command binding for possible user actions, Yes, No, Cancel... How do I Use? - Just place the necessary XAML tags in the view - Implement the command for all user actions in the View Model - Run unit tests on the commands

• How to implement Fog Of War with an shader?

  - by Cambrano

  Okay, I'm creating a RTS game and want to implement an AgeOfEmpires-like Fog Of War(FOW). That means a tile(or pixel) can be: 0% transparent (unexplored) 50% transparent black (explored but not in viewrange) 100% transparent(explored and in viewrange) RTS means I'll have many explorers (NPCs, buildings, ...). Okay, so I have an 2d array of bytes byte[,] explored. The byte value correlates the transparency. The question is, how do I pass this array to my shader? Well I think it is not possible to pass an entire array. So: what technique shall I use to let my shader know if a pixel/tile is visible or not?

• Azure

  - by Grant Fritchey

  I've been tasked to learn SQL Azure, as well as test all the Red Gate products on it. My one, BIG, fear has been that I'll receive some mongo bill in the mail because I've exceeded the MSDN testing limit. I know people that have had that problem. I've been trying to keep an eye on my usage, but, let's face it, it's not something I think about every day. But now I don't have to. Red Gate has been working with Azure, long before I showed up. They already released a little piece of software that I just found out about, it's called CloudTally. It gathers your usage and sends you a daily email so you can know if you're starting to approach that limit. Check it out, it's free.

• Which office suite is the ideal alternative to MSOffice?

  - by user64720

  Let's say I want to drop MSOffice permanently and switch to a free alternative, not having the need of opening the documents on other PC's except my own (I can also carry a portable version on a pendrive and edit the docs anywhere). I know 3 free office suites - LibreOffice, Abiword and Calligra. Which one of these is the most complete and provides the best features to be a viable alternative to MSOffice, without compromising the quality of the work I can produce on Office apps? Notice that I'm not focusing the question on compatibility between MSOffice and other suites but instead I am comparing their quality, taking in comparison MSOffice.

• What are the most important languages to localize for on the iOS App Store?

  - by Kevin Y

  It's obvious that to gain more customers on any given platform, one of the most important steps to take would be to localize your software into many languages: as many as possible, ideally. However, with independently developed apps, it tends to be difficult to localize into many different languages, due to not having the budget and / or time to do so. My question is if I were to localize my apps into languages other than English on the iOS App Store, which languages should I prioritize? (Maybe the top three or four most important.) (Also, let's pretend this is a generic app that won't cater more to one language demographic than another.)

• What's in a Name

  - by PointsToShare

  © 2011 By: Dov Trietsch. All rights reserved Microsoft – What’s in a name?   Long ago I heard a dentist joke. It went like this: A dentist went to a conference and at night he picked this girl and they went to his room. In the morning after, she asked: “Are you a dentist?” “Yes.” Said he. “You must be a very good one.” “I am. How did you guess?” “I didn’t feel a thing!!” That let my wild imagination roam. “Had it been Bill gates,” I thought, “the punch line would have been: ‘Now I know why you called it Microsoft!!” That's All Folks

• How to tell google a blog article has been updated?

  - by Scott

  The URL of my posts has the publication date and slugged title, but how can I best show google search users that an article has been updated since its original publication? I was considering devoting a few characters of the meta description (e.g. "updated 2013-Aug-1), or doing so under the first h1 tag. I don't want to hurt the seo value of my site, but I also want to let users know that articles have been substantially updated since their publication. Is there a better way to do this?

Please let me know if you require any additional information while addressing this problem and as always, thank you for your time.

• What design pattern do you use to support graceful fallback on old platforms?

  - by JoJo

  Let's say I need to add a drop shadow behind a box. Some old platforms do not support drop shadows, so I have to fake it by putting an image behind the box. Here's the pseudo code of how I'm currently handling this fallback: if (dropShadowsAreSupported) { box.addDropShadow("black"); } else { box.putImageBehindIt("gaussianBlur.png"); } Is this the right way to handle it? It seems too amateur to me. Is there a better design pattern?

• Manually activate Network Manager Applet

  - by diosney

  The issue I've is that when I connect via modem through gnome-ppp the Network Manager Applet don't detect a connection and don't let me use the configured VPNs via its interface. How Can I manually activate the Network Manager Applet? What I need is to enable the Network Manager apple in order to use the "VPN Connection" section of the GUI. When I don't have an ethernet cable connected and I connect through a modem the Network Manager applet doesn't enables itself, it is like if don't recognizes the ppp0 interface. My question is: there is a way to force the Network Manager GUI indicator to make it "alive"/"up"/"enabled" in order to use the "VPN Connections"section? Thanks in advance.

• Why do software patches have to be accepted by a developer?

  - by Nigel

  In open source projects, why do software patches have to be accepted by a developer? Couldn't contributors just release their own patches and allow people to add the patch if they choose to. I'm wondering why there are so many Ubuntu programs that could use such obvious work but aren't updated. For instance, lots of people want Rhythmbox to be more attractive. Why can't the people who design themes on DeviantArt turn those into code and let users download those themes themselves, even if the developers at Rhythmbox won't accept different themes?

• delete /var/cache/* How can I fix it?

  - by user110474

  I accidentally remove all files in /var/cache/ directory with sudo rm -rf command. Now I can not see the files in Trash to bring them back. I would like to know how bad is the situation if these files are removed? does ubuntu going to work normally and recreate the directories in cache again automatically? If not, which directories do I have to create in /var/cache/ manually to let everything work fine? I have already manually made apt and apache2 and debconf in cache directoy but I do not know if I miss more importand directory which needed to be created there. I hope somebody can guide me to fix this issue.

• How to properly express programming proficiency in CV?

  - by Pouya

  I'm rewriting my CV and I have a very hard time to express my programming skills in an honest matter while not underrating myself. How would you classify programming skill in four or five levels from complete beginner to god-like? For sake of argument, let us consider C++. What words would you use to present your programming skills? For example who is an expert in C++ or which word has a higher impact: Expert vs. Experienced? Could you suggest me 5 words like above in ascending order? P.S. I was planning to ask this question in Academia.SE, however, at the end I realized that I want to know programmers answer to the question.

• SS7(M3UA, SCCP, TCAP, MAP) Stack

  - by Ammar Hameed

  I'm building an open source SMSC from scratch; it's almost finished, The SRI and the forwardSM operations are working, but I still have few things to do for the receiving part. I've built the SS7 stack already, but I'm using DB for saving the TCAP transactions IDs to be updated later to get/generate responses. My approach is this: I created memory table (heap table), saved the TCAP TID in the database, then compared the received TCAP TID with the TIDs saved in the database and then decide whether to end the TCAP session or continue. What is the best way to implement it? I'm thinking of doubly linked list that holds the TCAP TID. Am I going towards the right direction, or should I use another technique other than database or D-linked list? Should I leave it as it is, and let the database do the job for saving the TIDs? Please note that I'm using SCTP implementation available on Linux (lsctp) as a transport protocol, the language I'm using is C and the DB is MYSQL.

• OpenGL Get Rotated X and Y of quad

  - by matejkramny

  I am developing a game in 2D using LWJGL library. So far I have a rotating box. I have done basic Rectangle collision, but it doesn't work for rotated rectangles. Does OpenGL have a function that returns the vertices of rotated rectangle? Or is there another way of doing this using trigonometry? I had researched how to do this and everything I found was using some matrix that I don't understand so I am asking if there is another way of doing this. For clarification, I am trying to find out the true (rotated) X,Y of each point of the rectangle. Let's say, the first point of a rectangle (top,left) has x=10 y=10.. Width and height is 100 pixels. When I rotate the rectangle using glRotatef() the x and y stay the same. The rotation is happening inside OpenGL. I need to extract the x,y of the rectangle so I can detect collisions properly.

• Tracking Search Filter Parameters Using Google Analytics

  - by Petra Barus

  I'm just wondering if there is a way to do this using Google Analytics. Let's say I have a search filter like the one used in Trulia.com There is a text search for the location with other drop-downs for filtering by bedroom, land size, property type (apartments, house) etc. Is there a way to track the filter and obtain a report for some questions like below using Google Analytics What is the most popular property types (house, apartments) for search in New York area? What is the most common maximum price of users who are looking for apartments in San Francisco? (or actually Google Analytics is not suitable for this kind of thing?)
