• Program to scale any OpenGL/DirectX window 2x larger?

  - by Neeb

  I would like to run some game on windowed mode, but its hard to see the game when my desktop resolution is huge. One solution could be to change my desktop resolution every time i play the game. But the bad thing is that my screen automatically smoothes the pixels when im using non-native resolutions, and the blurred pixels really makes it ugly and hard to look at. Is there some program to double the pixel size of any opengl/directx window without smoothing the pixels? I've tried multiple magnifying glass programs, but they all seem to make it blurred...

• How to make Windows 7 show all column headings the same for all folders?

  - by ????

  I have a few .rmvb files in a folder (these are the RealPlayer files but also playable by VLC) -- they are video files. Only .rmvb files but nothing else are in this folder. I don't know why the smart Windows 7 by default makes the folder show up with Album name, Artist name, Track #, Title, as if this is a folder for songs. (were the programmers sleeping when they program Windows 7?) Is there a way to just make all folders behave the same -- just to show filename, size, type, and Date Modified, and that's it -- for all folders and nothing fancy?

• Why can't I change the icon being displayed for a desktop shortcut?

  - by Bill

  I wanted to change the icon showing for a shortcut on the desktop, which points to a .Net utility I created for myself. I rebuilt the exe after changing the icon used within the project. In Windows Explorer the new icon shows in all size variations for the exe. In the 'Change Icon' dialog from the Properties option, the correct icon is showing as present, yet when I Apply it remains with the old icon? Even when I delete the shortcut and create a new one pointing to the newly built exe the old icon somehow is assigned?

• Should I upgrade memory for my dedicated server?

  - by mc1000

  My memory usage hangs around 25% (swap is generally 1%) on my dedicated server and load is around 2-5. My host recommended that I upgrade from 2GB of ram to 4GB so that I can increase my innodb_buffer from the default 16MB to 2GB. My innodb table size is 2GB. My question is, given that ram usage is 25% does it make sense to upgrade ram? Queries are hanging sometimes, so I'm thinking that a bigger innodb_buffer could decrease load on the database, just not sure if I really need to upgrade my ram first.

• Dialog boxes font is missing in Windows 7

  - by forgetso

  About 3 years ago I messed up my laptop with some virus removal software. It's obviously changed the registry settings and the text in dialogue boxes in the control panel, run box, etc. is the wrong size. See image:http://i.stack.imgur.com/SlFFU.jpg I've tried changing the MS Shell Dlg registry values to different fonts and restarting. I've made sure that I have the fonts SSERIFE.FON and SERIFE.FON on my system and that they are correctly referenced in the registry. Does anyone know how to fix this? I'd like to be able to see all of the options in the dialog boxes! Cheers

• Data structure for grid with negative indeces

  - by The Secret Imbecile

  Sorry if this is an insultingly obvious concept, but it's something I haven't done before and I've been unable to find any material discussing the best way to approach it. I'm wondering what's the best data structure for holding a 2D grid of unknown size. The grid has integer coordinates (x,y), and will have negative indices in both directions. So, what is the best way to hold this grid? I'm programming in c# currently, so I can't have negative array indices. My initial thought was to have class with 4 separate arrays for (+x,+y),(+x,-y),(-x,+y), and (-x,-y). This seems to be a valid way to implement the grid, but it does seem like I'm over-engineering the solution, and array resizing will be a headache. Another idea was to keep track of the center-point of the array and set that as the topological (0,0), however I would have the issue of having to do a shift to every element of the grid when repeatedly adding to the top-left of the grid, which would be similar to grid resizing though in all likelihood more frequent. Thoughts?

• Model View Controller² [closed]

  - by user694971

  I am working on a quite complex web application in Go and I tried to stay in an MVC pattern. However, I ended up having a structure isomorphic to this: /boilerplate The usual boilerplate an application needs to survive in the wilderness /db Layer talking to an SQL DB /helpers Helpers /logic Backend logic, not directly affiliated with any routes, sessions etc. /templates View /web Glue between /logic and /templates. In more dynamic languages the size of /web would be next to zero. But Go doesn't exactly have a RoR integrated so I need a lot of helper structures to feed the templates with data, to process GET/POST parameters and session information. I remember once reading about patterns similar to MVC with one extra letter but Wiki-searching I couldn't find it right now. (BTW currently /logic also contains data retrieval from API services to fill some hash maps; this is no simple task, but that probably belongs into the model, right?) So question: is this structure considered sane? Or does it need some bending to be tagged MVC app?

• Java single Array best choice for accessing pixels for manipulation?

  - by Petrol

  I am just watching this tutorial https://www.youtube.com/watch?v=HwUnMy_pR6A and the guy (who seems to be pretty competent) is using a single array to store and access the pixels of his to-be-rendered image. I was wondering if this really is the best way to do this. The alternative of Multi-Array does have one pointer more, but Arrays do have an O(1) for accessing each index and calculating the index in a single array seems to take one addition and one multiplication operation per pixel. And if Multi-Arrays really are bad, can't you use something with Hashing to avoid those addition and multiplication operations? EDIT: here is his code... public class Screen { private int width, height; public int[] pixels; public Screen(int width, int height) { this.width = width; this.height = height; // creating array the size of one index/int for every pixel // single array has better performance than multi-array pixels = new int[width * height]; } public void render() { for (int y = 0; y < height; y++) { for (int x = 0; x < width; x++) { pixels[x + y * width] = 0xff00ff; } } } }

• Can You Specify Where LVM Snapshots Are (Initially) Stored?

  - by bottles

  Disclaimer: this is my first time using lvm. Upon RTFM, it appears that LVM snapshots are automatically stored in the same directory as the original logical volume. In my case, that would mean the /dev directory. This isn't very nice, because there's not enough disk space in there for me to store a large snapshot. So when I run a command like lvcreate --size 1G --snapshot --name snapshot /dev/lvmData/usr, I need an additional 1G of space free in /dev? Is there any way to specify a different directory in which to store my snapshot?

  - by Toan Tran

  I have a netbook, with window 7 starter. I was trying to change the wallpaper, and found this application: John's Background Switcher which said that I can make slide show of themes, I guess it's as you set wallpaper with window 7 ultimate. The default wallpaper was still fine until downloading that application. After trying it, error occurred, I couldnt change the background, so I closed it, but then the default wallpaper changed its size, the central image dropped out of screen, can see aaprt of it on `bottom right hand corner. I tried to adjust the image into center, but it didnt work when i right click on desktop - Graphic option - panel fit - "center image". Anybody can help me? how to adjust it back to normal as original?

• Linux virtualized screen resolution

  - by vladev

  Hopefully there is a positive answer to this question: I have a 15.4" laptop with native screen resolution of 1920x1200. You can imagine that everything is completely unreadable by default. If I increase the font size it becomes readable, but ugly. Is it possible to set the "real" resolution to 1920x1200 so it plays nice with the monitor, but set some "virtual" resolution of 1440x900 so that everything starts looking nice. Note: If I just change the resolution to 1440x900 everything becomes blurry, since this is not the monitor's default resolution. I know that having a small monitor with high resolution is not very optimal - not my choice. (Using nvidia GF8400M)

• How to remove a drive from a 2-drive RAID 5 array?

  - by DrSAR

  There is some information available on shape changes in RAID arrays but I'm a little nervous and would like confirmation: Problem: I have 2 500GB drive as software raid 5 (mdadm). I would like to free one of the two drives since RAID-redundancy is for wimps... Can I just mdadm --grow --array-size=1 followed by a mdadm --grow --raid-disks 1? This seems too simple. How would I specify which drive gets freed? Part of the reason for this maneuver is that I don't have additional space to run a backup.

• Does the QPI figure matter for large scale data processing using SAS?

  - by xiaodai

  At work we use SAS to manipulte large amounts of data everyday on our workstations. To give an indication of scale the largest merges we had to do was merging 24 files of 2GB in size each together into one big file (if you are familiar with SAS the files are binary compressed too!). If we upgrade our PCs to core i7 then which of Core i7 975 or Core i7 960 is better? The main difference between the two seems to be QPI. So does that affect large scale data processing such as merge datasets in SAS?

• How to select all ActiveX objects in an area using a mouse in Excel?

  - by enderland

  Because of this problem with ActiveX objects changing size, I am not grouping my ActiveX objects in my Excel worksheet. Grouping them causes my solution hack to not work which is quite annoying. However, I often times want to be able to essentially use the mouse and select a region and then select all ActiveX objects contained in the region. This would also be useful for easily selecting objects to group them initially. Basically: Use mouse to select area Automatically select all ActiveX components in region I'm fine with a VBA solution if needed. How can I do this?

• How do I get any number of links to space evenly? [migrated]

  - by Aerodynamo

  Alright, so here is the situation... Say I have a navbar for a site, and I allow users to change the number of links they want on this navbar. This means they could have 3, 5, 10, etc. What I want to do is make it so that if one link is up, it only takes up, say, 1/5th of the space on the navbar. If I weren't using borders, I might do something like: width: 18%; padding: 0 1%; However, I have two problems with this: 1) For 4 buttons, that's fine that it doesn't fill up the whole row. It would look ugly if the links were too wide... but when I have 6 or 7 buttons, it's got huge overflow! 2) Since I have borders, I can't use a percentage value for the borders or the widths, because I can't properly estimate how much of the percentage it will be. Now, I know I don't have to use percentage values, but what I would ideally prefer is that the first button is the smallest possible size necessary for all the other buttons to fit properly, meaning that if I have 950px and 6 links, the first link can be about 150px while the others are 160px... that's fine. I want all the other buttons on the navbar to be equally sized, regardless of how many links there are. I also need for it to accept a border... I figure the way to do this is to put a border in the nested div, so that way it doesn't effect the overall width of the button? This is all well and good, but I'm still plagued by the issue of not being able to design a dynamic site using the style I want if I can't get all the nav buttons to fit the width properly. Are there some js tricks I could use? I don't even know... Thanks

• What monitor specifications should be taken into consideration to avoid eye problems? [closed]

  - by coding crow

  I spent time programming on my 13.3" laptop for 8 to 10 hours a day. I was planning to buy a good monitor. Now that I have developed CVS buying a monitor has became an immediate priority. I have spend some time trying to understand what I should buy and why. I could only zero down on the size (20") and LED. So, I'm looking for advice on many other factors like resolution, pixel density, panel technology and so forth. What should I look for in a computer monitor to avoid further eye problems? Why?

• what is standard approach to create a responsive website using javascript,php ajax and perhaps zend framework [closed]

  - by shawndreck

  I am working on a web system currently and plans to heavily use javascript with ajax to make the user interface more friendlier, not fancy as such. The javascript will be used for client side form validation, data loading from server and creating proper content with the result, also to for floating windows during add/edit or external references. Here is a scenerio that could clearify my question. A user wants to update card but instead of jumping to another page to verify the available colors,size and prizes of product, those information are shown in a floating window and changes in the floating window can affect the underlying one. My question is : 1. What are some of the approaches to encounter this situation? 2. Are there any helpful tips, tricks and links on this subject? I am comfortable with js,php and zend. I would appreciate any advice,tip and tricks, problem solving approach to handle a situation like this! Thanks in advance. Hope this make sense.

• How can I tell when an FTP is complete?

  - by identry

  I have a cron job that processes files that my client's upload via FTP to my FreeBSD server. The cron job runs once an hour, and normally processing each file only takes a few seconds. The cron job looks in the client's upload directory and moves any new files to a tmp directory. It then processes the file(s) and moves them into a final directory where they are then available to the public through a website. The problem is, every once in awhile, the cron job runs just as a new file is being uploaded. It moves the half-uploaded file to the tmp directory, and tries to process it, and fails, of course. Question: how can I determine if the uploaded file is complete? The only thing I can think of is checking the file size to see if it's changing, but that seems like a kludge. Is there some sort of flag or something that is set when the upload is complete?

• How should I implement multiple threads in a game? [duplicate]

  - by xerwin

  This question already has an answer here: Multi-threaded games best practices. One thread for 'logic', one for rendering, or more? 6 answers So I recently started learning Java, and having a interest in playing games as well as developing them, naturally I want to create game in Java. I have experience with games in C# and C++ but all of them were single-threaded simple games. But now, I learned how easy it is to make threads in Java, I want to take things to the next level. I started thinking about how would I actually implement threading in a game. I read couple of articles that say the same thing "Usually you have thread for rendering, for updating game logic, for AI, ..." but I haven't (or didn't look hard enough) found example of implementation. My idea how to make implementation is something like this (example for AI) public class AIThread implements Runnable{ private List<AI> ai; private Player player; /*...*/ public void run() { for (int i = 0; i < ai.size(); i++){ ai.get(i).update(player); } Thread.sleep(/* sleep until the next game "tick" */); } } I think this could work. If I also had a rendering and updating thread list of AI in both those threads, since I need to draw the AI and I need to calculate the logic between player and AI(But that could be moved to AIThread, but as an example) . Coming from C++ I'm used to do thing elegantly and efficiently, and this seems like neither of those. So what would be the correct way to handle this? Should I just keep multiple copies of resources in each thread or should I have the resources on one spot, declared with synchronized keyword? I'm afraid that could cause deadlocks, but I'm not yet qualified enough to know when a code will produce deadlock.

• Computers with Small Capacity SSD - For caching?

  - by RXC

  Recently, in newsletters from websites, I have been seeing computers for sale from manufacturers that include an HDD and an SSD but the SSD has a small capacity like 24 GBs. I don't know if this still holds true, but I learned that when building a computer, you would want to install your OS on your fastest hard drive. I do a lot of PC gaming, so I install my OS and games on my SSD, because I learned that games and many applications make lots of system calls to the OS and performance can only be as fast as the slowest piece. Why these computers come with small capacity SSDs? Most OS's take up around 20 to 30 GBs of space, so what are the benefits of such a small SSD? Are these small size SSDs for caching? and what exactly does caching mean (what does it do and how does it help)?

• RAID 0 disk failure, how to recover the RAID?

  - by user7985

  Situation is this. A PC with 2 hard disks, in an RAID 0 Array. The electronics on one of the disks has failed. I can not find the same board for the disk (I've tried this, removed board from the OK disk, and the second, the damaged one, works fine). I've made an image with "dd" on linux on a new hard drive (same size, not same model) and now I get "Offline member" in the RAID config screen. Will I succeed to recover the data which is stored on the drives, any help, any experience with this kind of problem. And surly, I know it was stupid to put the disks in RAID 0 and store data on them :(
