  • Results stored in a session - good idea?

    - by Nick
    To give a bit of background, lets say it's a generic results page, which is paginated so there are X results per page. Generally to do this, I have two queries on the page: to get the total number of results to get the results, limiting by the correct page's resultset However, recently I've been trying to cut down on the queries the site is making, and I thought one way to do this would be to only do the query if any parameters to the page have changed (except of course the page number)? This would then cache all the result id's in a session, which can be sliced when I need to return the correct resultset for that page. I was trying to look around the net to see if there are downsides of this method, but I've found very little information about it. Has anyone done this before? Is it a good idea?

  • Multiplication for MVP matrices: Any benefits to doing so within the vertex shader?

    - by Nick Wiggill
    I'd like to understand under what circumstances (if any) it is worth doing MVP matrix multiplication inside a vertex shader. The vertex shader is run once per vertex, and a single mesh typically contains many vertices. All MVP inputs remain the same for each vertex in the vertex batch relating to a given draw call (model). Surely then, you're always better off keeping the multiplications in the client code, such that you pass in the whole MVP precalculated as a uniform? (avoiding redundant ops between individual vertices)

  • Cheap ways to do scaling ops in shader?

    - by Nick Wiggill
    I've got an extensive world terrain that uses vec3 for the vertex position attribute. That's good, because the terrain has endless gradations due to the use of floating point. But I'm thinking about how to reduce the amount of data uploaded to the GPU. For my terrain, which uses discrete / grid-based vertex positions in x and z, it's pretty clear that I can replace my vec3s (floats, really) with shorts, halving the per-vertex position attribute cost from 12 bytes each to 6 bytes. Considering I've got little enough other vertex data, and an enormous amount of terrain data to push into the world, it's a major gain. Currently in my code, one unit in GLSL shaders is equal to 1m in the world. I like that scale. If I move over to using shorts, though, I won't be able to use the same scale, as I would then have a very blocky world where every step in height is an entire metre. So I see these potential solutions to scale the positional data correctly once it arrives at the vertex shader stage: Use 10:1 scaling, i.e. 1 short unit = 1 decimetre in CPU-side code. Do a division by 10 in the vertex shader to scale incoming decimetre values back to metres. Arbirary (non-PoT) divisions tend to be slow, however. Use (some-power-of-two):1 scaling (eg. 8:1), which enables the use of a bitshift (eg. val >> 3) to do the division... not sure how performant this is in shaders, though. Not as intuitive to read values, but possibly quite a bit faster than div by a non-PoT value. Use a texture as lookup table. I've heard that this is really fast. Or whatever solutions others can offer to achieve the same results -- minimal vertex data with sensible scaling.

  • How to sum and divide in MySql [migrated]

    - by Nick
    Alright, so I have a user table and would like to get the max value for the user with the highest amount of points divided by a score. Below is a rough idea of what I'm looking for: SELECT MAX(SUM(points)/SUM(score)) FROM users I'm not interested in adding up both columns and dividing, rather I'm interested in dividing the points and score for each user and retrieve the highest value out of the lot.

  • Rotate Rigged and Animated Scene?

    - by Nick
    I have a rigged and animated mesh that I need to import into Unity. We several characters that all use the same script, and access their bones to do procedural animations as well. The problem is that the new model I was given is facing the wrong way. Instead of facing forward, the model is facing the right.. Is there any way to rotate the model with it's animations without screwing it up, so that it will import properly in unity facing forward? Because of the way it was done, selecting everything in the scene and just rotating it by 90 degrees ruins some of the animations, so I need a program that can fix this.

  • Wubi doesn't install Ubuntu

    - by Nick
    I've tried 4 times on 2 different computers. After downloading wubi, and installing Ubuntu inside Windows XP, I restart and get the dual boot screen. I choose Ubuntu, and then nothing, my screen flashes for a few minutes with the Ubuntu colors. I restart and go to Ubuntu recovery, where it says "shadow passwords now on" and "clock off by a day-Fixed". I restart to only get the same thing, but Xubuntu, in stalled on one, but it's Ubuntu I want to try. Any thoughts ??

  • Dual Boot Windows 8 and Ubuntu

    My laptop has two hard drives, one 320GB HDD and a 30GB SSD. I installed Windows 8 on the HDD and Ubuntu on the SSD. However, after I installed Ubuntu, Windows 8 did not appear on the boot list. I tried boot-repair, but this didn't help.Here is the output of my fdisk -l: Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x6cd9314a Device Boot Start End Blocks Id System /dev/sda1 * 2048 625139711 312568832 7 HPFS/NTFS/exFAT Disk /dev/sdb: 30.0 GB, 30016659456 bytes 255 heads, 63 sectors/track, 3649 cylinders, total 58626288 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x6cd93132 Device Boot Start End Blocks Id System /dev/sdb1 * 2048 207126 102539+ 83 Linux /dev/sdb2 208894 58626047 29208577 5 Extended /dev/sdb5 208896 4112383 1951744 82 Linux swap / Solaris /dev/sdb6 4114432 58626047 27255808 83 Linux Disk /dev/mmcblk0: 3965 MB, 3965190144 bytes 49 heads, 48 sectors/track, 3292 cylinders, total 7744512 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0009c694 Device Boot Start End Blocks Id System /dev/mmcblk0p1 * 8192 7744511 3868160 b W95 FAT32 I also tried sudo grub-update, but that also did nothing.

  • Can anyone recommend a good SMS gateway for PHP?

    - by Nick
    I'm looking for an SMS gateway that has the following criteria: Supports sending from short codes Opt-in capabilities for end-user (will require user to opt in before sending message) Has a clean API, preferably an XML/ REST API, although SOAP is fine The cheaper the better Honestly, I keep searching and searching all permutations of "SMS Gateway API" etc... on Google and I can't find any great services that can support all of these criteria. There are a lot of really SEO optimized sites and I can't tell which of them are legit. I'm looking for something that will be easy and quick to implement, and none of my colleagues have any recommendations. What APIs have you used (preferably with PHP) that have gotten this job done? Which services have been the most pleasant to deal with, both technically and support-wise? Update: Will be sending primarily (probably solely) in the US.

  • Is it possible to modify a video codec + distribute it?

    - by Nick
    this is my first question on this particular stackexchange node, not sure if it's the most appropriate place for this question (if not, guidance to the appropriate node would be appreciated). the abstract: I'm interested in modifying existing video codecs and distributing my modded codecs in such a way as to make them easily added to a users codec library... for example to be added to their mpeg streamclip, ffmpeg etc. some details: I've had some experience modifying codecs by hacking ffmpeg source files and compiling my hacked code (so that for ex: my version of ffmpeg has a very different h.263 than yours). I'm interested now in taking these modified codecs and somehow making them easily distributable, so others could "add them" to their "libraries." Also, I realize there are some tricky rights/patent issues here, this is in part my motivation. I'm interested in the patent quagmires, and welcome any thoughts on this as well. ctx link: if it helps (to gauge where I'm coming from) here's a link to a previous codec-hacking project of mine http://nickbriz.com/glitchcodectutorial/

  • What are the app file size limitations for different smartphone OSes & carriers?

    - by Nick Gotch
    I know the iPhone App Store limits how large an app can be in general and there are also limitations with AT&T over the size it can be to transmit over a data plan vs WiFi. I have no idea what, if any, these limits are for Android apps and what I'm finding online is a mix of different numbers. Does anyone know these numbers definitively? The Android game I'm porting is in the 20-30MB range and we'd like to know if we need to further reduce its size.

  • Dynamic quicklist: how to reference to .desktop file? (installed in /opt)

    - by Nick Lemaire
    I'm trying to create a dynamic quicklist for an application I'm developing in quickly. This is the line of code I use to try and connect to the .desktop file: self.launcher = Unity.LauncherEntry.get_for_desktop_id("my-app.desktop") For testing purposes, I've found that when using quickly run I should copy the .desktop file to ~/.local/share/applications. When I do this, the quicklist shows up correctly. However, when packaging my app using quickly package --extras, and installing this package, I get a launcher without quicklist. Does this have something to do with my app being installed in /opt? Meaning my desktop file is located somewhere else? Should I use another reference to the desktop file?

  • Is it correct to refer to a performing programming assignments as a "computer labs"?

    - by Nick Rosencrantz
    Can we say that developing an algorithm is a "laboration"? Are these "labs"? At engineering performing an exercise or an assignement is refered to as "labs" but are those "labs" when in fact it is mainly software problem solving pretty much like numeric methods in math which are not "labs". When studying engineering such as electrical engineering or physics you might do a "laser lab" or a "chemical laboration" if you study chemical engineering for instance. How do you define "lab"? Just performing something experimental? This is sort of double meaning also the physical environment at universities which we call "computer labs" that in fact are just rooms with computers.

  • Why has extreme programming (XP) gone out of date in favor of Agile, Kanban etc?

    - by Nick Rosencrantz
    I like XP (extreme programming) especially the part where there are 2 programmers at the same screen since often a problem's solution gets closer if only you explain what you're doing and pair programming forces you to explain what your doing. Last 10 years or so, the XP style of working seems to have gone out of date in favor of the working methodologies Agile and/or Kanban. Why? Since XP to me seems a veru good way to work and is a lot about the programming where Agile and Kanban are more about processes.

  • Should I use SVG for icons? [on hold]

    - by Nick Maddren
    I'm just wondering what is the preferred practice for adding icons? I see quite a bit of hype over SVG images however having a bit of trouble understanding how they are implemented as every article I read seems out of date. I need icons for simple lists, the icons need to be one solid color. I feel as if using png's was so 2008 haha, would you recommend the use of SVG images or are developers using other methods to display icons now?

  • Great site for creating color schemes

    - by Nick Harrison
    I have recently discovered a website that is a must have for any developer who has struggled with picking the colors for their web site:  http://colorschemedesigner.com/ You get several choices to determine how to specify the colors. This option brings in a complimentary color in various shades along with the main color that you select on the color wheel. You also have the option of specifying various adjustments to the schema. You can make it pastel, more contrast, less contrast, gray tones, etc. You can also view a preview page as a light page or a dark page to see how the colors might be applied.  Once you have everything the way you want it, you can switch over to the final tab and get the color list. Now none of us have an excuse for questionable color combinations.

  • How to hide website's real address

    - by Nick
    I'm building a website for public use. It's a sharing website - everyone is allowed to download specific content, but I want to make sure nobody knows where all the files are kept, so I've decided to use URL Forwarding, e.g. when someone visits fakesite.com, it returns realsite.com without revealing/redirecting to realsite.com. Question: I don't know how to make this work. Please help me by explaining how to use URL Forwarding! Thanks!

  • VMWare Unity Mode with Ubunty 12.10

    - by Nick
    This is a very difficult thing to search for, and find an answer to because of the unfortunate choice VMWare and Ubuntu both having something called "Unity". My host operating system is Windows 7 - 64 bit, running VMWare Workstation 9.0.1. I have a virtual machine running Ubuntu 12.10 - 64 bit. When I attempt to put VMWare in "Unity mode", I get the following message: The virtual machine cannot enter Unity mode because: - Unity is not supported on the guest operating system. From the VMWare site, there is nothing listed that says that Ubuntu is not supported for this... and I have installed the latest vmware-tools on the guest operating system. It seems like a lot of people have had this issue, but I haven't seen a good resolution to it yet. Does anyone know how to get Unity mode working with Ubuntu?

  • How would I migrate a front page form based site to an IIS7 server? [on hold]

    - by Nick Gilpin
    I have an large html website on a very old server and I'm attempting to move it to a brand new server running IIS7. I've tried moving the entire site to the WWW directory, but then all my forms return "The HTTP verb POST used to access path is not allowed". Additionally, all the solutions I've found online only work on a page by page basis. Is there a simpler/faster way to migrate a large website containing many forms to IIS7? Here is the specific error message: The HTTP verb POST used to access path '/FormServer/Mig/_vti_bin/shtml.dll/admissions/askseaaggie.htm' is not allowed.

  • How can I make my generic comparer (IComparer) handle nulls? [closed]

    - by Nick G
    Hi, I'm trying to write a generic object comparer for sorting, but I have noticed it does not handle the instance where one of the values it's comparing is null. When an object is null, I want it to treat it the same as the empty string. I've tried setting the null values to String.Empty but then I get an error of "Object must be of type String" when calling CompareTo() on it. public int Compare(T x, T y) { PropertyInfo propertyInfo = typeof(T).GetProperty(sortExpression); IComparable obj1 = (IComparable)propertyInfo.GetValue(x, null); IComparable obj2 = (IComparable)propertyInfo.GetValue(y, null); if (obj1 == null) obj1 = String.Empty; // This doesn't work! if (obj2 == null) obj2 = String.Empty; // This doesn't work! if (SortDirection == SortDirection.Ascending) return obj1.CompareTo(obj2); else return obj2.CompareTo(obj1); } I'm pretty stuck with this now! Any help would be appreciated.

  • Is there a data structure for this type of list/map?

    - by Nick
    Perhaps there's a name for what I want, but I'm not aware of it. I need something similar to a LinkedHashMap in Java, but where it returns the 'previous' value if there's no value at the specified key. That is, I have a list of objects stored by an integer key (which is in units of time in my case): ; key->value 10->A 15->B 20->C So, if I were to query for a value for key 0-9, it would return null. The special part is if I queried for something 10 <= i <= 14 it would return A. Or, for i = 20, it would return C. Is there a data structure for this?

  • Are there Windows virtual images available for development? [closed]

    I want to test deployment of a Windows application and a virtual PC seems the easiest method (I could be wrong, feel free to comment, but the question still stands). Courtesy my Windows 7 I have Virtual PC, and I seem to recall way back in XP I could download a pre-made image for Virtual PC 200x(7?) and use that without having to install from media. Are there any similar images for developers for Virtual PC?

  • Are Intel and Motorola moving towards a MIPS/RISC model? [closed]

    - by Nick Rosencrantz
    Is it true what I read that Intel and Motorola are moving from CISC to a programming model more like RISC/MIPS? Why? From the famous book "Computer Architecture" by Hennessay which usually is recommended around here: Recent implementations of the x86 architecture actually translate x86 instruction into simple operation that look like MIPS instuctions.... Page 335. What does this mean specifically? Can you show me an example?
