  • What does "kTriangles/s" mean in hardware graphics benchmark reports?

    - by swquinn
    I've looked around and found several sites offering benchmarking statistics for mobile platforms and I've been seeing the unit of measure as "kTriangles/s". Originally I misread this, missing the 'k'; does this translate to "thousand(s) of triangles/s", e.g.: 8902 kTriangles/s = 8,902,000 triangles/s (I'm pretty sure that my interpretation is correct, but I hope someone can confirm this for me) Thanks!

  • Should I use scaffolding or not in Ruby on Rails?

    - by dpacmittal
    I'm learning Ruby on Rails for a new project of mine. I am referring the book 'Agile Web Development with Rails' which shows how to build a shopping cart and they use scaffolding. I'm pretty familiar with MVC architecture and have used several frameworks in PHP to build applications. I've never used scaffolding and I'm not sure if that's the best way to start building an application. Experienced users, please suggest if I should be using scaffolding or should I code manually.

  • Is this Java 7 security thread an issue if you have Java 7 installed but not as the default?

    - by user1361315
    I have a MBP with osx mountain lion installed, and I believe from what I read Mac's only ship with Java 6 by default. I'm not at my computer at the moment, but I am pretty sure I have installed Java 7 but it isn't my default java version (I think I installed it and I have to explicitly reference it to use it). Does this mean I am safe from this particular thread? Reference: http://www.pcworld.com/businesscenter/article/261748/researchers_find_critical_vulnerability_in_java_7_patch_hours_after_release.html

  • 3 Tools to Automate Your SEO Efforts

    When it boils down to it, a lot of SEO is pretty autonomous and mundane. We all know that we need links to get the high rankings but the thought of having to spend hours submitting to directories is enough to make me find a million and one other jobs - even going as far as calling the in-laws! You can outsource the submission process but it's become debatable just how effective these submissions are, you could be throwing the money away.

  • I need a very rapid game engine with as many presets as possible [closed]

    - by GLycan
    I have to make a game about the immune system (with as many grotesque simplifications as I want) in roughly two weeks. I'm thinking of something along the lines of bubble tanks, but I think I can roll with pretty much anything that fits the following: Working engine that handles mouvement, objects The fighting system can be done in any way that allows a bare minimum of configuration Scripting should be, preferably, Python Art should be customizable I'm hoping that there is some existing game that I could adapt. Any sggestions (aside from not leaving projects until later) ?

  • Tiling Problem Solutions for Various Size "Dominoes"

    - by user67081
    I've got an interesting tiling problem, I have a large square image (size 128k so 131072 squares) with dimensons 256x512... I want to fill this image with certain grain types (a 1x1 tile, a 1x2 strip, a 2x1 strip, and 2x2 square) and have no overlap, no holes, and no extension past the image boundary. Given some probability for each of these grain types, a list of the number required to be placed is generated for each. Obviously an iterative/brute force method doesn't work well here if we just randomly place the pieces, instead a certain algorithm is required. 1) all 2x2 square grains are randomly placed until exhaustion. 2) 1x2 and 2x1 grains are randomly placed alternatively until exhaustion 3) the remaining 1x1 tiles are placed to fill in all holes. It turns out this algorithm works pretty well for some cases and has no problem filling the entire image, however as you might guess, increasing the probability (and thus number) of 1x2 and 2x1 grains eventually causes the placement to stall (since there are too many holes created by the strips and not all them can be placed). My approach to this solution has been as follows: 1) Create a mini-image of size 8x8 or 16x16. 2) Fill this image randomly and following the algorithm specified above so that the desired probability of the entire image is realized in the mini-image. 3) Create N of these mini-images and then randomly successively place them in the large image. Unfortunately there are some downfalls to this simplification. 1) given the small size of the mini-images, nailing an exact probability for the entire image is not possible. Example if I want p(2x1)=P(1x2)=0.4, the mini image may only give 0.41 as the closes probability. 2) The mini-images create a pseudo boundary where no overlaps occur which isn't really descriptive of the model this is being used for. 3) There is only a fixed number of mini-images so i'm not sure how random this really is. I'm really just looking to brainstorm about possible solutions to this. My main concern is really to nail down closer probabilities, now one might suggest I just increase the mini-image size. Well I have, and it turns out that in certain cases(p(1x2)=p(2x1)=0.5) the mini-image 16x16 isn't even iteratively solvable.. So it's pretty obvious how difficult it is to randomly solve this for anything greater than 8x8 sizes.. So I'd love to hear some ideas. Thanks

  • best way to import 500MB csv file into mysql database?

    - by mars
    I have a 500MB csv file that needs to be imported into my mysql database. I've made a php file where i can upload the csv file and it analyses the fields n stuff and does the actual importing. but it can only handle small fiels max 5mb. so that's a 100 files and actually pretty slow(uploading) is there another way? I have to repeat this process every month because the data in the file changes every month it's about 12 000 000 lines :D

  • BinarySerialization size not consist?! (2 replies)

    Hello all, I have met something pretty odd. I am running a serialization on an object and not always the size of the output stream is the same. I even created a test that I am running the serialization in a loop, and each time I am running I have different results sizes in some point in the loop. This happens when I am using a object that was filled in the server side, and I get them thru WCF work...

  • Defining pages by custom variable, reporting to Google Analytics

    - by zwolfson
    Does anyone know how I could add some information to my page (whether in a meta tag or some other way) to indicate to Google Analytics that a page is targeted to a certain segment? This is pretty straightforward on my main site where everything is set up in hierarchy by target user so I can just use the URL to filter the data. However for my subdomains, its a flat structure that's just a bunch of landing and conversion pages so I can't use the URL. Any help would be much appreciated. Thanks

  • When Canonicalization is an Issue

    Although extremely hard to pronounce, canonicalization is a hot topic right now. If there are a lot of URLs that lead to pretty much the same page, you're going to make the search engines work extra hard and spend a lot more time crawling all the different URLs. Often times, this means that they'll miss the important pages of your website because your crawl time is limited or too slow.

  • Is my work on a developers test being taken advantage of?

    - by CodeWarrior
    I am looking for a job and have applied to a number of positions. One of them responded, I had a pretty lengthy phone interview (perhaps an hour +) and they then set me up with the developers test. I was told that this test is estimated to take between 6 and 8 hours and that, provided it met with their approval, I could be paid for my work on it. That gave me some pause, but I endeavored. The dev test took place on a VM accessed via RDP. The task was to implement a search page in a web project that requests data from the server, displays it on the screen in a table, has a pretty complicated search filtering scheme (there are about 15 statuses and when sending the search to the server you can search by these statuses) in addition to the string/field search. They want some SVG icons to change color on certain data values, they want some data to be represented differently than how it is in the database, etc. Loooong story short, this took one heck of a lot longer than 6-8 hours. Much of it was due to the very poor VM that I was running on (Visual Studio 2013 took 10 minutes to load, and another 15 minutes to open the 3 GB ginormous solution). After completing, I was told to commit my changes to source control... Hmm, OK. I get an email back that they thought that the SVGs could have their color changed differently, they found a bug in this edge-case, there was an occasional problem with this other thing that I never experienced, etc. So I am 13-14 hours into this thing now and I have to do bug fixes. I do them, and they come back with some more. This is all apparently going into a production application. I noticed some anomalies in the code that was already in there where it looked like other people had coded all of one functionality and not anything else that I could find. Am I just being used for cheap labor? Even if they pay me the promised 50 dollars and hour for 6 hours, I have committed like 18 hours to this thing now. If I bug fix all of the stuff they keep coming up with, I will have worked at least 16 hours for free. I have taken a number of dev tests. I have never taken one where I worked on code that was destined for production. I have never taken one where I implemented a feature that was in the pipeline for development (it was planned for, and I implemented it through the course of the test). And I have never taken one that took 4 rounds and a total of 20+ hours. I get the impression that they are using their dev test to field some of the functionality, that they don't have time for in their normal team, on the cheap. Also, I wouldn't mind a 'devtest' tag.

  • Transition Player Position

    - by Lycrios
    I'm currently working on a java MMO with a pretty solid start, but I've come across an issue I need a little help with. I'm working on player position's. Meaning there X/Y on the screen, if the PlayerA has a higher FPS(Frames Per Second) then other players, the resulting action will be that PlayerA will move faster than everyone else. I know the reasoning for this, it's because when the game draws I just use: x++; What would a better method be?

  • Does SEO Matter?

    Too often companies claim to be Internet Marketers, but fail to deliver. This usually refers to web development and design companies that do nothing more than create pretty websites.
