  • How to draw a spotlight in 3D

    - by RecursiveCall
    To be clear, I am not talking about the light result (the lit area) but the spotlight itself, like this The two common suggestions that I tried are 2D image and a 3D cone. The problem with the pre-regenerated 2D image is that it always look 2D and flat no matter how it is rotated in world space. The cone on the other hand is next to impossible to control when it comes to fade distance, it doesn't look soft (smooth) and it is expensive to compute.

  • Which is better a computer science degree or a Software engineer degree?

    - by Shadow wolf
    I'm asking here so since you all have experience in or around game programming, that's what I want to do, and I’m trying to find as many options as I can before my senior year, which is next year. So do you have any opinions on the matter of which would give me a better education in programming? Please no talking about anything other than the two degrees because I know of game programming degrees out there but I like to see which of these would provide the best alternate choice.

  • How to decompose a rectangular shape in a Voronoi diagram, only generating convex shapes?

    - by DevilWithin
    I think this is a very straighforward question, lets say i have a building in 2D, a rectangle shape. Now i want to decompose that area in a lot of convex shapes, as seen in a voronoi diagram, or closely like it, just so I can add those shapes to the physics engine, and have a realistic destruction. Bonus: Possible suggestions on how to make the effect more dynamic and interesting. Please keep in mind we re talking about realtime calculations..

  • T-SQL Tuesday #015:Remaining on Alert

    - by AllenMWhite
    This T-SQL Tuesday is about Automation in SQL Server, and I'll bet you think I'm going to talk about PowerShell. Well, you're partially right. What I'd like to talk about today, though, is setting up alerts to automate some responses to naturally occuring phenomena on your SQL Servers. (Note: I first introduced this technique in an article on Simple Talk here ). Without going back to the original article, I'm talking about a safety valve process for when your transaction logs start to fill at rates...(read more)

  • Do you use unit tests at work? What benefits do you get from them?

    - by Anonymous
    I had planned to study and apply unit testing to my code, but after talking with my colleagues, some of them suggested to me that it's not necessary and it has a very little benefit. They also claim that only a few companies actually do unit testing with production software. I am curious how people have applied unit testing at work and what benefits they are getting from using them, e.g., better code quality, reduced development time in the long term, etc.

  • Help yourself . if you like

    - by rachelp
    At Red Gate we enjoy talking to our customers. Really! If you've read recent blog posts by members of some of our customer-facing teams, you'll have spotted the pleasure they take in their work. In case you missed those posts, here they are: From our Finance team: Finance: Friends, not foes! From our reception desk: The Front line of Communication However, we recognise that sometimes our customers would like to be able to solve their problems or answer their questions without talking to us - they're in a hurry, it's outside office hours . or perhaps they just prefer not to pick up the phone and call.   Self-service customer care So we've begun a programme of work to enable more self-service; whether it's finding the answer to a "how do i.?" question or getting access to a record of what product licenses they own, we want to make it much easier for our customers to get hold of this information for themselves. If they want to.   Phase 1: make it easier to find information We decided to start by tackling findability. We've got loads of useful information on our website, but it's sometimes difficult to find, so we've been working on improving our site search. Step 1 has been to replace the search engine, clean up the search UI, and make it consistent across the site. We're nearly there! The idea is that if we improve the site search it will be easier - and much more pleasant - for people to find the information they need. The new search will go live some time in April, and then we'll be gathering feedback, looking at web analytics (more about this in an earlier article), and working out what improvements we still need to make. We'd love to hear what you think, so do give your feedback or drop us a line. Or pick up the phone and call, if you like.   What do you think? While I've got your attention, I'd love to hear what people think about self-service customer care. Do you like to call, email, live chat . or do you prefer to dig around and find out answers yourself? Who's getting it right: what self-service sites do you like? p.s. Watch this space for news of phase 2.

  • If I project a sphere in 3D will it be a circle?

    - by yuumei
    Assuming I have infinite vertices to represent the sphere, if I project the sphere from any position/scale in 3D to 2D, will it be a circle? I know it will not be a circle on the screen, because of scaling and different resolutions. But do field of view and aspect ratio effect the results? Edit: Sorry yes, I am talking about perspective projection. Seems the answer is no then, perspective will distort the sphere. Thanks!

    <b>Distrowatch:</b> "When talking about kernel scheduling and desktop responsiveness, it's common to hear people in the tech community talk fondly of BeOS, a desktop system which hails from the 1990s.

  • Upgrade from 12.04 to 12.10 Failed due to network troubles

    - by user99100
    Every time I try and upgrade from 12.04 to 12.10 it keeps telling me that there are network problems. Is this a problem on "the other" side? My upgrade got through downloading half the packages last night but then went into sleep and then failed. Could it have something to do with that? Would I need to open a terminal and clear a "cache" (no idea what I'm talking about here) Thanks (Solved now, tried it again through out the day and it downloaded and installed fine)

  • What is Deep Linking and How is it Useful For My Website?

    People talking about deep linking, well I don't honestly see it a lot, but it's definitely very powerful, when you can understand how/why it works and how you can create deep backlinks, you'll be able to understand how to improve the traffic you get from Google, but ranking for more keywords. Deep link is more or less building backlinks to inner pages of your website, for example instead of just building backlinks for your index/domain, you should really build backlinks to your inner pages as well.

  • Social Media Marketing Needed For Search Engine Optimization

    In John Jantsch's book "The Referral Engine" talking about search engine optimization he says: "It has become extremely difficult to achieve any measure of success for important keyword phrases without the use of social media. (The flip side is that the organizations that take advantage of social media can dominate, particularly within industries slow to adapt.)"

  • Oracle @Munich Business School

    - by Maria Sandu
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Last Wednesday, Lisa from the Graduate Recruitment team and her colleague Philipp from Sales visited the Munich Business School to talk about IT challenges, Sales and Career Opportunities at Oracle. Although the talk started at 6:30 pm, the audience of about 100 students was still attentive and curious. First they were provided with some facts about Oracle, then Philipp went into detail and took them through current IT challenges like ‘Social’, ‘Mobile’, ‘Information’ and ‘Cloud’ and how Oracle solutions can help facing these challenges. He also demonstrated what kind of prerequisites and qualifications are required to become a successful Sales person. When talking about his own career, the audience got even more anxious to hear what he would tell them. Finally, students asked questions on career opportunities across Europe or on other topics they were interested in.

  • QNTC and Windows Server 2008 R2

    - by Ben
    I am having a really hard time getting an iSeries (AS/400) machine talking to my new Windows Server 2008 R2 box using the QNTC file system on the iSeries. I had similar problems getting it to initially talk to a Windows Server 2003 machine, but enabling the local Guest account on the 2003 box solved that one. No such luck with the new 2008 box. When I do a WRKLNK /QNTC/SVR01 on the iSeries (which should show share listings, and does on any 2003 boxes) all I get is (Cannot find object to match specified name.). I know the iSeries likes the same username and password on the remote server, but unfortunately for us this is not the case. Anyhow, it does currently work with different username/password combinations on a 2003 box. To try and get the wretched things talking, I have made the 2008 server pretty open but the iSeries will not see shares on it. I have enabled the local Guest account, turned Windows firewall off, set the share permissions so Everyone has full control but to no avail. I read something on the internet about the iSeries only being able to handle NTLM authentication (and I understand by default that Server 2008 R2 only uses NTLMv2 and has NTLM disabled), so I made a special group policy for the server and tweaked all Group Policy settings under Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\Security Options but the iSeries STILL won't see it. We have a team of programmers who do all the system administration of the iSeries, but they are stumped for ideas on their side, and I'm stumped for ideas on my side. This is driving me crazy now, and if anybody has managed to get an iSeries to talk to Windows Server 2008 R2 using QNTC I would be very appreciative of any suggestions, be it on the Windows side, iSeries settings or even IBM PTF's that might patch anything. The iSeries is running V5R4 and I have *SECOFR privileges on it, if it helps. One final (most important!) note - The programmers think it's my system being tricky, and I think it's theirs - please prove me right :)

  • Why doesn't apache2 consistently load template fragments from memcached?

    - by Hobhouse
    I run a webserver on an ubuntu box in the rackspacecloud with django 1.0x, apache2/WSGI and memcached 1.2.2. Some of my templates make use of template fragment caching: {% load cache %} {% cache 604800 keyname %} <!-- cache: {% now "H:i, j. b" %} --> {{ my_content }} {% endcache %} When I reload apache2 everything is fine. If keyname is not set, my_content is generated and keyname is set in memcached. After that, my_content is served from memcached. My problem is that after some hours (notably less time than 604800 seconds ), apache2 seems to stop talking to memcached, and my_content is generated from scratch everytime. When this happens I can still set and get keys from memcached from my python shell. Memcached also has more than enough memory to store keys. But to get apache2 to start talking to memcached again I have to restart apache2, and then it will once again start to get the now several hours old keys from memcached. What can be the reason for this behaviour, and how do I fix it?
