• How do I save to an NTFS partition?

  - by RADHAKRISHNAN

  I was using ubuntu 11.04 on my Laptop. While installing it from a DVD, I have created a 10 GB NTFS partition at the beginning of the hard disk, as primary. All other partitions ( swap, a ext3, a ext4 and a FAT32 ) are created in as logical in the extended partition. All were working well in ubuntun11.04. Now the system was upgraded to ubuntu 11.10 via internet and was sucessful. But unable to either create folder/files or to write to existing files in the said NTFS partiton. But files in the partition can read - means mounting done. Same is the case even if logged in as root also. Fortunately no such problem with other partitions including FAT Why it is so, please help.

• Depth is disabled - How to turn on?

  - by marc wellman

  In XNA 3.1 is there any other way to disable depth in 3D Worlds using DirectX models other than GraphicsDevice.RenderState.DepthBufferEnable = false; ? The reason for my question is I have quite a huge program which offers a 3D World with a couple of 3D DirectX models inside. Depth was never an issue since it ever worked fine but since a few days after doing some modifications my models are all depth-translucent i.e. depth-buffering and/or culling seems to be disabled. But in my whole source code I never touch any of the options related to Depth or Culling which means I never turn these settings on explicitly nor turn it off somewhere. So I am searching for some other statement maybe related to the GraphicsDevice that implicitly turns depth off - but I can't find it. (Sorry that I don't post any source code but I have too much source code and I simply don't know where to search) UPDATE: These are a couple of simple objects seen with correct depth. These are the same objects in their current state.

• What Are Some Tips For Writing A Large Number of Unit Tests?

  - by joshin4colours

  I've recently been tasked with testing some COM objects of the desktop app I work on. What this means in practice is writing a large number (100) unit tests to test different but related methods and objects. While the unit tests themselves are fairly straight forward (usually one or two Assert()-type checks per test), I'm struggling to figure out the best way to write these tests in a coherent, organized manner. What I have found is that copy and Paste coding should be avoided. It creates more problems than it's worth, and it's even worse than copy-and-paste code in production code because test code has to be more frequently updated and modified. I'm leaning toward trying an OO-approach using but again, the sheer number makes even this approach daunting from an organizational standpoint due to concern with maintenance. It also doesn't help that the tests are currently written in C++, which adds some complexity with memory management issues. Any thoughts or suggestions?

• Help comparing Cocos2d and Unity3d for this project [closed]

  - by Omega

  I will not go into details, but I would like to hear your opinions about this: Essentially, my project will be a 2d game, with lots of complex levels, where some might be simple and others might be a bit more deep, with physics, etc. We want to implement our very own online structure: logging in, leaderboards, achievements, friends etc with our own servers. This means no OpenFeint nor GameCenter at all. We expect this game to be very large in both graphics and audio. We wish to use in-app purchases. Now, we considered two options. Cocos2d and Unity3d. We need help deciding using the factors I mentioned before (networking, good performance even for a large game in terms of graphics and audio like this, in-app purchases, etc) which option would fit better this? Technically, both options can create 2d games. I'd like to hear your opinion.

• Website hacked, cpanel password not encrypted?

  - by Jeg Bagus

  Yesterday I found out that all the websites that are hosted on my webhosting site were hacked. I tried to change my password, and unbelievably, I COULD SEE my password there. This means my password is able to be decrypted. I asked customer support, and they say, its normal, CPanel saves the password like that. Is it true? I mean, cpanel password able to be decrypted? They blame me because my wordpress version is out of date. But 2 of my website are on different platforms. One made by CI and one by Wordpress, and all are hacked. Is this hosting reliable?

• Alerts are good, aren't they?

  - by fatherjack

  It is accepted best practise to set some alerts on every SQL instance you install. They aren't particularly well publicised but I have never seen any one not recommend setting up alerts for Error 823, 824 and 825. These alerts are focussed on successful access(IO) to the hard drives that SQL Server is using. If there are  any errors when reading or writing to the drives then one of these errors will be returned. Having the alerts on these errors means that any IO issues will be brought to the...(read more)

• How do I comperes and split files with terminal

  - by Levan

  So what I wanted to do. comperes(7zip) and split 600MB folder into 199MB parts but sadly when I tried to do this task with archive manager it gave me an error, but I know that if I use terminal it will work. I looked this up in askubuntu and found out about this commend 7z a -v5m -mx0 ubuntu.7z I understand that v5m will split it to 5 mb parts and -mx0 means that it will not comperes it but I want it to comperes so what should I write instead of this -mx0 pleas note: I am using .7zip because I most probably will use this file on windows pc thank you in advanced

• Component based design, but components rely on eatchother

  - by MintyAnt

  I've begun stabbing at a "Component Based" game system. Basically, each entity holds a list of components to update (and render) I inherit the "Component" class and break each game system into it. Examples: RenderComponent - Draws the entity MovementComponent - Moves the entity, deals with velocity and speed checks DamageComponent - Deals with how/if the entity gets damaged... So. My system has this: MovementComponent InputComponent Now maybe my design is off, but the InputComponent should say things like if (w key is down) add y speed to movement if (x key is down) Trigger primary attack This means that the InputComponent sort of relies on these other components. I have to do something alone the lines of: if (w key is down) { MovementComponent* entityMovement = mEntity->GetMovement(); if (entityMovement != NULL) add y speed to movement } which seems kinda crappy every update. Other options? Better design? Is this the best way? Thanks!

• How would you answer this job-interview question?

  - by ahmed

  One of the five people who interviewed me asked a question that resulted in an hour-long discussion: "Explain how you would develop a frequency-sorted list of the ten thousand most-used words in the English language." My initial response was to assail the assumptions underlying the problem. Language is a fluid thing, I argued. It changes in real time. Vocabulary and usage patterns shift day-to-day. To develop a list of words and their frequencies means taking a snapshot of a moving target. Whatever snapshot you take today isn't going to look like the snapshot you take tomorrow or even five minutes from now. Thanking you advance for your answers and consideration.

  SQL Saturday #300 is coming up right here in Kansas City on September 13th, 2014.  This is our fifth SQL Saturday which means it's the fifth anniversary of our now infamous BBQ Crawl.  We get together on Friday afternoon before the event and visit a few local joints.  We've done nice places and we've done dives.  We haven’t picked the venues yet but I promise you’ll be well fed! And if you’re thinking about the BBQ crawl you should think about submitting a session.  Our call for speakers closes Tuesday, July 15th so you just have time!  If you’re going to be at the event, contact me and I’ll get you added to the list.

• 3D array in a 2D array

  - by Smallbro

  Currently I've been using a 3D array for my tiles in a 2D world but the 3D side comes in when moving down into caves and whatnot. Now this is not memory efficient and I switched over to a 2D array and can now have much larger maps. The only issue I'm having now is that it seems that my tiles cannot occupy the same space as a tile on the same z level. My current structure means that each block has its own z variable. This is what it used to look like: map.blockData[x][y][z] = new Block(); however now it works like this map.blockData[x][y] = new Block(z); I'm not sure why but if I decide to use the same space on say the floor below it wont allow me to. Does anyone have any ideas on how I can add a z-axis to my 2D array? I'm using java but I reckon the concept carries across different languages.

• How To Remove Authorized PCs from Your Windows Store Account

• How do I create a big multiplayer world in UDK?

  - by Dorpe

  I want to create a big multiplayer world in UDK and I'm having a few difficulties. I created the biggest terrain possible but then any terrain related action I do takes forever. However, I've seen videos of people make same size terrain and working without a problem. My pc is strong enough, so maybe someone can tell me what I'm doing wrong. I want to make it even bigger then the biggest terrain size, so I was thinking of doing level streaming but then I read that streaming is working server side which means if I have a player on every terrain all terrains will still be loaded and I want to save as much memory possible so it will work well online. Thanks for any help you can give.

• What exactly does "keyword" mean in the context of AdSense CPC?

  - by deltanovember

  I have read in a lot of places that CPC depends on the value of "keywords". However I don't understand what this means. I will set forward some scenarios. Suppose I run a blog about knitting and this is a low paying niche. However I suddenly write five frontpage blog posts about forex trading and insurance. When people click on the frontpage ads, would I be getting paid for the low CPC knitting content or for the high paying forex content? Suppose somebody finds my webpage by searching for knitting. However the actual content of the landing page is filled with high paying keywords. Is the CPC for this page determined by the low paying search or the high paying content?

• After installing Ubuntu 12.10, Windows 8.1 disappears from start up menu

  - by Vaz

  I'm very new to Ubuntu (12.10), so I apologise if I'm not clear at any point! I had a Windows 8 (upgraded to Windows 8.1) and was fed up with it, so I converted to Ubuntu 12.10. I'd hoped to Dual Boot to at least get the benefit of both worlds. I created a partition for it in Windows and installed from a LiveUSB key (and installed into that parition). So now Ubuntu works great, but Windows 8.1 no longer shows up on the start up screen (where you theoretically pick which OS you want to boot in). I was going to try "Boot Repair" as mentioned here and restore MBR, but I don't want to start messing around with stuff I'm not entirely clear with. EDIT: For any of those who stumble here with the same problem, I just read here that a user wiped out his Windows partition by accident... I checked my own computer with sudo fdisk -l and there's only one Device Boot (dev/sda1). I'm not an expert, but I'm guessing that means Windows has been written over.

• Clarify the Single Responsibility Principle.

  - by dsimcha

  The Single Responsibility Principle states that a class should do one and only one thing. Some cases are pretty clear cut. Others, though, are difficult because what looks like "one thing" when viewed at a given level of abstraction may be multiple things when viewed at a lower level. I also fear that if the Single Responsibility Principle is honored at the lower levels, excessively decoupled, verbose ravioli code, where more lines are spent creating tiny classes for everything and plumbing information around than actually solving the problem at hand, can result. How would you describe what "one thing" means? What are some concrete signs that a class really does more than "one thing"?

• will main domains be more seo friendly than subdomains?

  - by C graphics

  Web hosting providers offer services such as hosting multiple domains in one account. Then my concern is about seo friendliness. say the main domain of my account is maindomain.com on which I have added an addon domain say domain2.com. That means cpanel will generate domain2.maindomain.com and the contents of domain2.com will be practically stored into a subfolder in maindomain.com. Now, assume both maindomain.com and domain2.com have same structure both optimized for seo same way. My question is that would maindomain.com links be more seo friendly due to that fact that maindomain.com is the mani domain of my account?

• Ubuntu 12.04 GNOME Terminal (3.4.1.1) Xorg 100% CPU

  - by EaZ

  after upgrading Ubuntu 11.04 to 12.04 (x64 arch) maximizing or resizing GNOME Terminal (3.4.1.1) windows larger cause the Xorg (1.11.3) or X process to utilize 100% CPU. Resizing smaller, moving windows or minimizing do not seem to have the same impact but by no means are snappy either. I'm running on a Dell E6500 laptop (upgraded from 11.04) running the nvidia proprietary drivers v. 295.49 (Quadro NVS 160M) with compiz 0.9.7.8. Other terminals such as xterm/uxterm are unaffected. Hoping it has to do with some configuration settings but not sure where to look (nvidia/compiz/gnome/X?). Thanks!

• Euler Problem 20

  - by MarkPearl

  This was probably one of the easiest ones to complete – a quick bash got me the following… The Problem n! means n (n 1) ... 3 2 1 For example, 10! = 10 9 ... 3 2 1 = 3628800, and the sum of the digits in the number 10! is 3 + 6 + 2 + 8 + 8 + 0 + 0 = 27. Find the sum of the digits in the number 100! The Solution   private static BigInteger Factorial(int num) { if (num > 1) return (BigInteger)num * Factorial(num - 1); else return 1; } private static BigInteger SumDigits(string digits) { BigInteger result = 0; foreach (char number in digits) { result += Convert.ToInt32(number)-48; } return result; } static void Main(string[] args) { Console.WriteLine(SumDigits(Factorial(100).ToString())); Console.ReadLine(); }

• How to create reproducible probability in map generation?

  - by nickbadal

  So for my game, I'm using perlin noise to generate regions of my map (water/land, forest/grass) but I'd also like to create some probability based generation too. For instance: if(nextInt(10) > 2 && tile.adjacentTo(Type.WATER)) tile.setType(Type.SAND); This works fine, and is even reproduceable (based on a common seed) if the nextInt() calls are always in the same order. The issue is that in my game, the world is generated on demand, based on the player's location. This means, that if I explore the map differently, and the chunks of the map are generated in a different order, the randomness is no longer consistent. How can I get this sort of randomness to be consistent, independent of call order? Thanks in advance :)

• RPi and Java Embedded: Hard-Float Support is Here!!!

  - by hinkmond

  You wanted Java Embedded with Hardware Floating Point support to install on a default Raspian environment for your Raspberry Pi? Well, you just got your wish. Merry Christmas! See: Developer JDK 8 for ARM w/Hard-Float Here's a quote: The Java SE 8 Developer Preview Release for ARM including JavaFX (JDK 8) on Linux has been made available at http://jdk8.java.net. The Developer Preview is provided to the community to get feedback on the ongoing progress of the project. Developers can start developing applications using this build of Java SE 8 on an ARM device, such as the a Raspberry Pi. It's a regular JDK (Java SE 8 preview) for your Raspberry Pi, so you should note this means there is a javac (and the other typical JDK tools) available to compile your Java apps right there on the device! Woot! I'll cover step-by-step instructions how to do that in a future blog post. Stay tuned... Hinkmond
