• Is it possible to construct a cube with fewer than 24 vertices

  - by Telanor

  I have a cube-based world like Minecraft and I'm wondering if there's a way to construct a cube with fewer than 24 vertices so I can reduce memory usage. It doesn't seem possible to me for 2 reasons: the normals wouldn't come out right and per-face textures wouldn't work. Is this the case or am I wrong? Maybe there's some fancy new DX11 tech that can help? Edit: Just to clarify, I have 2 requirements: I need surface normals for each cube face in order to do proper lighting and I need a way to address a different indexes in a texture array for each cube face

• Why does this script not open parallel gnome-terminals on a server?

  - by broiyan

  Why am I not able to have parallel gnome-terminals on my server while I can on my client. Here is a test that illustrates the problem. #!/bin/bash # this is the parent script gnome-terminal --command "./left.sh" sleep 10 gnome-terminal --command "./right.sh" #!/bin/bash echo "this is the left script" read -p "press any key to close this terminal" key #!/bin/bash echo "this is the right script" read -p "press any key to close this terminal" key When I run this on a regular ubuntu desktop (maverick) I see two terminals after 10 seconds. When I run this on a maverick server at a server farm, the second window does not appear until after I close the first one and wait 10 seconds. I am using tightvncserver to view the server desktop. (I could have simplified a bit more. The 10 second sleep is extraneous to the problem. In my real world application I need the first terminal to do some real work before starting the second. The problem probably still exists even if there is no sleep.)

• Java EE @ No Fluff Just Stuff Tour

  - by reza_rahman

  If you work in the US and still don't know what the No Fluff Just Stuff (NFJS) Tour is, you are doing yourself a very serious disfavor. NFJS is basically a set program of world class speakers and topics offered at major US cities year round. I am proud to share with you that I recently joined the legendary NFJS troupe. My hope is that this will help solve the lingering problem of effectively spreading the Java EE message here in the US. I had my tour debut on April 4-5 with the NFJS New York Software Symposium. I did four of my most favorite talks and it was not that bad for a start - I have more in the coming months in Columbus Ohio, Denver Colorado and Austin Texas. More details on the tour posted on my personal blog. Hope to see you on the tour soon?

• The First Microsoft Dynamics NAV Builds on TFS 2010 Server

  - by ssmantha

  We are now successfully, able build Dynamics NAV solutions using the TFS Build workflow mechanisms. Lots of test builds were made, the builds can restore the NAV Database and start from a fresh solution, take latest of the NAV objects and then import it to Navision and call the compile method. The workflow is also able to generate FOB files as output which can be directly shipped to the customers. I think this is the First in the world implementation of the TFS build concepts in conjunction with NAV. I think this is a time to change the thinking caps and try to approach ERP development and include the practises of ALM into ERP Product Development.

• Log oddities: 404s for client-garbled image URLs

  - by Chris Adams

  I've noticed some odd 404s which appear to be broken URL rewriting code: Our deep zoom view generates images URLs like this: /media/204/service/dzi/1/1_files/7/0_0.jpg I see some - well under <1% - requests for slightly altered URLs: /media/204/s/rvice/d/i/1/1_files/7/0_0.jpg These requests come from IP addresses all over the world (US, Canada, China, Russia, India, Israel, etc.), desktop and mobile users with multiple user-agents (Chrome, IE, Firefox, Mobile Safari, etc.), and there is plenty of normal activity in the same session so I'm assuming this is either widespread malware or some broken proxy service. I have not seen them from anything other than images, which suggests that this may be some sort of content filter. Has anyone else seen this? My CDN logs show the first request on June 8th ramping up from several dozen to several hundred per day.

• No OpenCL devices (13.10 Core I5 4430 Intel Graphics HD)

  - by Itai Bar-Haim

  I've been looking quite a lot for this but couldn't find anything that worked. I have an Intel Core I5-4430 based system with no extra graphics adapter (so it's using the on-board, integrated Intel Graphics HD that is part of the CPU), running Ubuntu 13.10. When running BOINC World Community Grid it says "No usable GPUs". When running a bitcoin mining program it says "No OpenCL devices". I searched the web, found two possible solutions - one was to use the Intel OpenCL driver for Xeon platforms, the other was to use the AMD driver. Tried both. I failed installing the Intel driver as there were too many prerequisites that I just didn't manage to install, and the AMD installation was quite fast to its size (it's 200MB, and took far less than a minute to install), but it didn't solve the problem. Perhaps I'm looking in the wrong direction here, I'm not sure, but is there anyway I can utilize the advance features of my CPU for those distributed computation programs?

• Good Times and Vibes at Mix 10

  Last week I spent a few days in Las Vegas attending the Mix 10 conference. Mix is billed as A 3 day conference for web designers and developers building the world's most innovative web sites. Which certainly reflects its origins as a conference focused on the web and web standards. But this year, it seemed that the scope for Mix was expanded to be about, well, a Mix of technologies as the Windows Phone 7 series figured prominently at the conference.

• A question every programmer has. Maybe.

  - by zengr

  I have been using Java from the last 2yrs (academics). Now, when I am graduating, I received a job offer from a .com. The job is awesome and it's a backend Java work. I wanted to get involved with Ruby on Rails, looked for alot of jobs, gave few interviews, but didn't make it. So, what should I do now? Should I go ahead with Java and learn/do more with Java, a complete 360degree of the java world - Full stack of Java from backend to frontend? OR Java at workplace and try to improve my Ruby on Rails. I understand, this is a very subjective question and depends on the individual, but what would you have done? Have you ever faced a similar problem? I feel I have wasted some time with Rails, where I could not "conquer" Rails, where as I could have used that time to go more into Java.

• SANS Webcast: Label Based Access Controls in Oracle Database 11g

  - by Troy Kitch

  Controlling access to data subsets within an application table can be difficult and inefficient especially when faced with specific data ownership, consolidation and multi-tenancy requirements. However, this can be elegantly addressed using label based access control (LBAC). In this webcast you will learn how LBAC using Oracle Label Security and Oracle Database 11g can easily enforce row-level access based on user security clearance. In addition, Oracle security experts will discuss real world case studies demonstrating how customers, in industries ranging from retail to government, are relying on Oracle Label Security for virtual information partitioning and secure consolidation of information.  Register for the July 12 webcast now.

• Login timeout disable?

  - by Sk606

  How can I disable automatic timeout entries in the login screen? Allow me to explain. My typical experience goes something like this: I put my laptop to sleep, then wake it. When it wakes, it comes up with the login screen. I type in my password and it will usually reject it, with a message indicating the login timer has expired. I then enter my password a second time and it logs in. Not the end of the world, but annoying nonetheless. Any suggestions?

• How to fill certain application design learning "gaps"?

  - by e4rthdog

  In life it doesnt matter if you do one thing for 15 years. You will end up waking one day and asking stuff that are equal to "how do i walk?" :) My specific question is that as a new entrant to C# and OOP i am stepping into many little "details" that need to be addressed. Written a lot of code in VB.NET / cobol / simple php e.t.c surely does not help much into the OOP world... So , even after reading entry level books for C# and watching some videos i recently found out about the "factory model design" for applications. I would appreciate if any of you guys recomment some reading on application design architecture for further reading...

• Search engine friendly, SEO blog software

  - by Steve

  Is there a comparison of the SEO capabilities of different blogging software/blogging plugins? I'd like things to be as optimised as possible. I have a basic grasp of SEO principles, probably 12-24 months old. I'm about to start a blog, after having a few previously. Also, I'm not up to speed on what pings are in the blogging world. What are they, and how do they work? I assume it is best to have blogging software that automatically pings.

• Is it worth to learn programming for windows?

  - by Herr Kaleun

  as a programmer, i was skeptical about (Microsoft) desktop software back in the early 2000s (i was a kid then) and yet, i was right. So i advanced to PHP in 2004 and began working on Web applications. When i look at the software world today, i really can't understand, how software for Microsoft or call it, "windows" should have a future. Is it still worth, learning it? I have a strong feeling that, in about 3-4 years, mac will have the dominance in the Personal Computer market. If i am wrong, please correct me. Thanks!

• why not use unmanaged safe code in c#

  - by user613326

  There is an option in c# to execute code unchecked. It's generally not advised to do so, as managed code is much safer and it overcomes a lot of problems. However I am wondering, if you're sure your code won't cause errors, and you know how to handle memory then why (if you like fast code) follow the general advice? I am wondering this since I wrote a program for a video camera, which required some extremely fast bitmap manipulation. I made some fast graphical algorithms myself, and they work excellent on the bitmaps using unmanaged code. Now I wonder in general, if you're sure you don't have memory leaks, or risks of crashes, why not use unmanaged code more often ? PS my background: I kinda rolled into this programming world and I work alone (I do so for a few years) and so I hope this software design question isn't that strange. I don't really have other people out there like a teacher to ask such things.

• Channel 9 Video:SharePoint and WCF

  - by Sahil Malik

  Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). A VERY LONG TIME AGO :), Zhiming from Microsoft and I got together and talked a bit about why WCF is such a big deal in SharePoint. In this video we talk a bit about why SharePoint has been so successful. And why WCF in SharePoint can have a great positive impact on your productivity. A lot of what I say in that video is still applicable to SP2010, but that video was recorded before there was ANY information out in the general world about SP2010. Well, that video is now finally online .. enjoy! :) Comment on the article ....

• What are the most commonly used enterprise Java technologies, and what would you want a non technical audience to understand about them?

  - by overstood

  I have been asked to give a presentation to a non-technical audience on what Java technologies are currently being used in the enterprise world. The goal is to give this non-technical audience the background they need to understand what engineers are talking about. It's part of a broader series of talks that I'm giving. I'm primarily a .NET and C++ dev, so I thought I'd try to get some input from some Java devs. What technologies do you use? What Java related acronyms would you like to be able to use around non-coders? What would you like non-coders to understand about them?

• 3D Studio Max biped restrictions?

  - by meds

  I have a stock biped character in 3D studio max which has a jump animation. The problem I have with the jump animation is that there is actual y offset happening inside it which makes it awkward to play while the character is jumping since it's not only jumping in the game world but the jump animation is adding its own height offset. I'm tryuing to remove the jump animations height offset, so far I've found the root node and deleted all its key frames which has helped a bit. The problem I'm having now is that the character still has some height offset and if I try to lower it it has a fake 'ground' that isn't at 0 and the limbs sort of bend on the imaginary floor, si there a way to remove this restriction just for the jump animation? Here's what I mean: http://i.imgur.com/qoWIR.png Any idea for a fix? I'm using Unity 3D if that opens any other possibilities...
