• What advantages are conferred by using server-side page rendering?

  - by user1303881

  I am developing a web app and I have currently written the entire website in html/js/css and on the backend I have servlets that host some RESTFUL services. All the presentation logic is done through getting json objects and modifying the view through javascript. The application is essentially a search engine, but it will have user accounts with different roles. I've been researching some frameworks such as Play and Spring. I'm fairly new to web development, so I was wondering what advantages using server side page rendering would provide? Is it: Speed? Easier development and workflow? Access to existing libraries? More? All of the above?

• Access Token Verification

  - by DecafCoder

  I have spent quite a few days reading up on Oauth and token based security measures for REST API's and I am currently looking at implementing an Oauth based authentication approach almost exactly like the one described in this post (OAuth alternative for a 2 party system). From what I understand, the token is to be verified upon each request to the resource server. This means the resource server would need to retrieve the token from a datastore to verify the clients token. Given this would have to happen upon every request I am concerned about the speed implications of hitting a datastore like MySQL or NoSQL upon every request just to verify the token. Is this the standard way to verify tokens by having them stored in a RDBMS or NoSQL database and retrieved upon each request? Or is it a suitable solution to have them cached (baring in mind that we are talking millions of users)?

• What is the best way to INSERT a large dataset into a MySQL database (or any database in general)

  - by Joe

  As part of a PHP project, I have to insert a row into a MySQL database. I'm obviously used to doing this, but this required inserting into 90 columns in one query. The resulting query looks horrible and monolithic (especially inserting my PHP variables as the values): INSERT INTO mytable (column1, colum2, ..., column90) VALUES ('value1', 'value2', ..., 'value90') and I'm concerned that I'm not going about this in the right way. It also took me a long (boring) time just to type everything in and testing writing the test code will be equally tedious I fear. How do professionals go about quickly writing and testing these queries? Is there a way I can speed up the process?

• Alternative ways to construct maps

  - by sideways8

  I've searched around and it seems like most people are using tile-based map systems. I suppose this question is more theoretical than practical (I am not very concerned about memory or performance speed), but I want to know: what other ways can a map be created in a game? A map being a graphic representation of terrain that can be navigated, has entrances and exits, and boundares (no-go zones). Besides using text files to store and arrays to load tile data, one idea I had was to store a map entirely as a graphic file and use queries on the pixel colour to determine boundaries (ie, you can only move in a certain direction if the way is bright enough in that direction). What other creative map systems are out there?

• Empty Disk when trying to install dual-boot system

  - by Lambda Dusk

  I recently purchased an SSD to speed up my computer experience. Before, I had Windows 7 and Ubuntu in a dual-boot system. The plan was to install Windows 8 on the SSD and then set aside ~30GB for the system files of Ubuntu. I installed Windows 8 just fine on the SSD, then I booted the Ubuntu install CD to make my partitions like always - but GParted tells me the entire SSD is unallocated. Now I am afraid I will lose my Windows installation if I try to do anything to it. Why does GParted think there is no partition on the SSD? Shouldn't it be 4 Partitions, like the Windows installer told me? And is it possible to ignore this and install Ubuntu on the hard disk (where it, frankly, already is) and somehow make it possible to install GRUB on the SSD to revert my dual-boot system without damaging the installed Win8?

• Ubuntu Audio Pitch Shifting filter

  - by user777305

  I'm currently developing a video player software which intended to be an embeedded player. I'm using Java with VLCJ library for the video player. What i'm looking is a way, something to transform the audio output to make the output sound as oldman or a kid (pitch shifting, i guess is the name). VLC have this when enabling time stretch, but the video play speed is affected (slower to get oldman sound, but fast-forward-alike to get kid voice effect. Is there any solutions for this? I don't find this feature on VLC(J), so i think what i need is the audio output of the ubuntu itself (Ubuntu 12.04) to do this job. something like filtering audio output system wide. Any software or setting to do this? it also need to be controllable via command line to provide realtime effect changing. Thanks in advance.

• How can I run a complete application from RAM?

  - by pico

  When I do some stuff in background (unpacking, compiling, backup, etc.) my hdd is under load and for example, Firefox and Chromium take very long to start and react very slow. While my hdd is under load I have still plenty of free RAM and free CPU. How can I copy the whole Firefox or Chromium including all dependencies into RAM? I don't care about persistence, I just want to view some websites, videos, etc. There are instructions putting the cache into /dev/shm, but that didn't speed up so much. Getting the profile into the RAM drive might also be easy... But how to get the binaries with all dependencies into RAM?

• Targeting a vehicle with complex movement?

  - by e100

  Targeting a vehicle with known constant velocity is simple, and collision is guaranteed. Imprecise AI can be modeled by adding a small error factor. But how would one go about targeting a vehicle whose movements are more complex? Perhaps it's evading the AI or another game object. I've been thinking about how I'd do it myself in a FPS (in which bullets have finite speed) and think there might need to be at least couple of targeting modes based on the target's movement in the previous second or so: If it's near linear (peak acceleration in a certain range) target with the linear model If it's highly irregular (perhaps size of bounding box of recent positions could be used?) , target at an average For now I can assume 2d space, AI is stationary and projectile moves linearly.

• Can I properly use NS2 on latest Ubuntu 12.04?

  - by Nwe Nwe

  I am a novice user for Ubuntu because I need to work with NS2. NS2 properly work only in Linux, Ubuntu. Now, I wonder if it can properly work on latest version Ubuntu. My current window is Window7. I also want to use Window7. So, which one will be better on parallel booting of Window 7 and Ubuntu or using VMWare on Window7 to install Ubuntu. My RAM is 4G. My processor speed is 1.6G. If I use VMWare, my C drive is only extra 10G. So, does VMWare can work properly in D drive? Please let me know which way is the best for my situation. I hope the advice from anyone. Thanks in advance.

• Sharing Large Database Backup Among Team

  - by MattGWagner

  I work on a team of three - five developers that work on an ASP.net web application remotely. We currently run a full local database from a recent backup on all of our machines during development. The current backup, compressed, is about 18 GB. I'm looking to see if there's an easier way to keep all of our local copies relatively fresh without each of us individually downloading the 18 GB file over HTTP from our web server on a regular basis. I guess FTP is an option, but it won't speed the process up at all. I'm familiar with torrents and the thought keeps hitting me that something like that would be effective, but I'm unsure of the security or the process.

• Images from remote source - is it possible or is really a bad practice?

  - by user1620696

  I'm building a management system for websites and I had an idea related to image galleries that I'm not sure it's a good approach. Since images might need good deals of space depending on how much images a user uploads an so on, I thought on using cloud services like dropbox, mega and google drive to store images and load then when needed. The obvious problem is that for me this seems a useless solution because it would be slow to download the images from the remote source, making the user experience not so good. Is there any way to save images of a image gallery on remote source without getting the user experience bad because of speed? Or this is really not a good practice?

• Collisions and Lists

  - by user50635

  I've run into an issue that breaks my collisions. Here's my method: Gather Input Project Rectangle Check for intersection and ispassable Update The update method is built on object_position * seconds_passed * velocity * speed. Input changes velocity and is normalized if 1. This method works well with just one object comparison, however I pass a list or a for loop to the collision detector and velocity gets changed back to a non zero when the list hits an object that passes the test and the object can pass through. Any solutions would be much appreciated. Side note is there a more proper way to simulate movement?

• Sensitive middle-button (mouse)

  - by Gilead

  Whenever I click on the middle-button on my mouse-wheel, it seems that multiple click events are being sent in succession. Case in point: when I middle-click a bookmark folder in Chrome (to open up all the bookmarks in tabs), Chrome opens up the same set of bookmarks three times. This is very annoying. Is there a way in X or Gnome to detune the sensitivity of my mouse's middle button to prevent multiple click events from being sent? Maybe like a double-click speed adjustment for the middle-button?

• Estimating file transfer time over network?

  - by rocko

  I am transferring file from one server to another. So, to estimate the time it would take to transfer some GB's of file over the network, I am pinging to that IP and taking the average time. For ex: i ping to 172.26.26.36 I get the average round trip time to be x ms, since ping send 32 bytes of data each time. I estimate speed of network to be 2*32*8(bits)/x = y Mbps -- multiplication with 2 because its average round trip time. So transferring 5GB of data will take 5000/y seconds Am I correct in my method of estimating time. If you find any mistake or any other good method please share.

• Slow tranfer to external USB3 hard drive

  - by JMP

  Trying to backup data from hard drive before reloading windows following some issue with its load. Having trouble with the file transfer to a USB3/2 external hard drive NTFS. Getting transfer speed of about 116.7kB/sec. In other words its taking about 5 hours to tranfer 1.4GB. I've got about 80GB to go. So the transfer is going to take 11days. Seems a little on the slow side. Am I missing something? Is there a way to make this faster. No issue with the external drive tranferring this amount in windows. But don't have that option at the moment.

• nVidia GT 220 not working properly with Ubuntu 12.10

  - by Glaedr

  I used to enable proprietary nVidia drivers on every previous Ubuntu release to get it working properly (elseway I was forced to a very low resolution and no graphic acceleration), and everything worked fine then. In particular, I noticed - still I don't know why - that the GPU fan on every OS gets noisy until the video drivers are loaded (runlevel 5, it seems, in Linux), and then slows down to a normal speed. Today I installed 12.10. Running the Live CD, surprisingly, everything was working fine: full resolution, acceleration, silent fan, and so on. The running driver was nvidia-current (GT 216). After installing and booting I found that the fan was overrunning. The installed driver is nouveau. I tried installing nvidia-current, or any other proprietary driver, even installing the kernel headers & source and then the drivers (as suggested here), but all I'm getting with proprietary drivers is, the irony, low resolution, noisy fan and no acceleration (thus obviously unity and compiz refusing to start). Does anybody know a way out?

• Rendering trillions of "atoms" instead of polygons?

  - by Baring

  I just saw a video about what the publishers call the "next major step after the invention of 3D". According to the person speaking in it, they use a huge amount of atoms grouped into clouds instead of polygons, to reach a level of unlimited detail. They tried their best to make the video understandable for persons with no knowledge of any rendering techniques, and therefore or for other purposes left out all details of how their engine works. The level of detail in their video does look quite impressive to me. How is it possible to render scenes using custom atoms instead of polygons on current hardware? (Speed, memory-wise) If this is real, why has nobody else even thought about it so far? I'm, as an OpenGL developer, really baffled by this and would really like to hear what experts have to say. Therefore I also don't want this to look like a cheap advert and will include the link to the video only if requested, in the comments section.

• How can I disable as much "flair" as possible in Unity?

  - by UlfR

  I'm running Ubuntu 11.10 from a fresh install on a somewhat aged computer, so I have some speed problems. But since I do want to use the new cool way to work with things that Unity introduces I do not want to fiddle with getting another desktop environment. My idea is to disable as much flair as possible, but there are tonnes of options that I do not understand or have the time to read up on when I launch CompizConfig Settings Manager. Which of these could safely be disabled? Are there other places where performance could be gained by disabling things? So how can I make the whole thing a little more snappy?

• Simulating a sine wave/oscillating pattern for enemies

  - by Sun

  I'm creating a simple top down shooter, right now I have an enemy which simply follows the player. I'd like to change things up and have the enemies move towards the player but in a wave like motion. I have looked at some similar questions like this but they don't take into account for the Y changing. How can I simulate a wave like pattern for my enemies whilst they are homing into their target. Edit: Sample code In my update method I have the following: Vector2 trackingPos = position - target; trackingPos.Normalize(); position -= trackingPos * elaspedTime * speed;

• for vs. foreach vs. LINQ

  - by beccoblu

  When I write code in Visual Studio, ReSharper (God bless it!) often suggests me to change my old-school for loop in the more compact foreach form. And often, when I accept this change, ReSharper goes a step forward, and suggests me to change it again, in a shiny LINQ form. So, I wonder: are there some real advantages, in these improvements? In pretty simple code execution, I cannot see any speed boost (obviously), but I can see the code becoming less and less readable... So I wonder: is it worth it?
