  • What is the best language to use for building a fulfillment engine [on hold]

    - by John Stapleton
    I asked this on stack overflow and was suggested to move it here. I do understand it is a matter of opinion which is exactly what I aim to achieve here... I wanted to know what you think is the best language to write a fulfillment engine in? I cannot provide much detail but I am trying to build a control interface for servers and i wanted to build a program daemon that would process data on the authoritative server and the slave servers( the backbone of the network) with their own daemons running would check regularly(every 5 minutes or so) with the authoritative server and process the commands(securely) I am trying to build this with a minimal footprint(cpu and ram wise for the slaves, authoritative is going to be scalable) and to make it automated so that the user does not have to configure the daemon(installation is automated by the authoritative server) I am leaning away from my usual php set up for simplicity sake. Edit: I am not an expert in any particular language but flexible enough and willing to learn another.

  • PAE on Ubuntu 12.04

    - by JamesStewy
    I am having trouble using PAE on Ubuntu 12.04 LTS 32bit. I recently upgraded from 4 to 8gb of RAM but PAE doesn't appear to have picked this up. When I run "grep --color=always -i PAE /proc/cpuinfo" I get pae in the list. When I run "dmidecode | grep Size | grep MB" Installed Size is 3825 but the Maximum Total Memory Size: 8192 MB. When I check the BIOS it says there is 8192 MB available and the computer fully supports I have followed everything I can find on the internet (including this https://help.ubuntu.com/community/EnablingPAE) and nothing is working. My Computer is a Toshiba Portege m750. It has an Intel Centrino Core 2 Duo processor. Bought in 2009 Thanks, JamesStewy

  • Scale DIV with tiles

    - by user15350
    I am trying to create a repeating background. I have a main DIV with a grid of small 16x16 DIVs. I am trying to scale the main DIV in CSS; when the small DIVs simply have a red background color everything works great, but when there is a background image in the small DIVs then borders become visible between the tiles. This image explains the problem: http://cl.ly/FpNW/o Check the HTML in these examples: With BG-COLOR: http://jsfiddle.net/pTLXw/ With BG-IMG: http://jsfiddle.net/vkpuY/ Does anyone know what is causing this problem and how to fix it? If it is not possible to fix while using DIV, is there another way to do this? Thanks you so much!

  • Does anyone know of any work being done on EEE transformer?

    - by Matthew
    I recently got a (few) nexus 7's to install and enjoy ubuntu on. Which is great and all, but from what I've read online and the issues I have experienced myself the Nexus 7 has way to many serious defects. Such as: Audio jack not working Screen lifting Screen ghosting out (The very first one) Instant drop in battery life (happened to one of mine) Internal memory malfunctions (The latest issue I've had, the internal memory went completely bad) If you need to read other horror stories you can simply check out XDA developers forum, lots of people are having issues. I'd really like to enjoy ubuntu on a different device, I think the Transformer prime would make way more sense (usability and stability wise). Have there been any hacks/mods to get it running on this device?

  • Over-Current condition on port 7 or 8

    - by Dymatic
    I am having a problem with my USB ports. It shows over-current conditions on ports 7 and 8. I have heard that this is caused by a damaged USB port, and since it is detecting it on two ports it seems that I have two that are broken. I do indeed have two that do not work, so that is not the issue. What I would like to do is disable whatever program is running over-current condition checks. tty's are unusable at this point. Every few second a new over-current condition occurs. Here is the output of dmesg: http://pastebin.com/CuFKRGue Is there an easy way to disable these checks or damage the ports to a point where it will no longer check? Fixing them is not important or an option.

  • Oracle Linux Friday Spotlight - November 8, 2013

    - by Chris Kawalek
    Happy Friday, everyone! This week, I want to highlight a really wonderful resource, the Oracle Linux Wiki on wikis.oracle.com. You can find a lot of in-depth technical information there and it’s probably worthy of a bookmark to check in on occasionally. One of my favorite types of content on the wiki is the do it yourself hands on labs. We do these at in person events like Oracle OpenWorld and also online for our Virutal SysAdmin Days, and those are great because you can get real-time assistance if you have any questions. But, if you’re eager to learn more about Oracle Linux and don’t want to wait for one of those events, you can step through these labs in your own time. All of the information you need is on the wiki. We’ll see you next week! -Chris

  • Null Or Empty Coalescing

    In my last blog post, I wrote about the proper way to check for empty enumerations and proposed an IsNullOrEmpty method for collections which sparked a lot of discussion. This post covers a similar issue, but from a different angle. A very long time ago, I wrote about my love for the null coalescing operator. However, over time, Ive found it to be not quite as useful as it could be when dealing with strings. For example, heres the code I might want to write: public static void DoSomething(string...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Best practices on separating Update and Draw on game loop

    - by Galvanize
    I've been working on my first HTML5 prototype and I found a good model that uses the regular Update and Draw loop we see in game dev. My question is, where does one end and the other begins? The question popped when I wanted to rotate and draw an Image, and I kept wondering if the work of changing the tranformation matrix (that I presume would be a bit expensive since it works on the whole pixel array of an image) and calculating the right position do draw it would characterize drawing work, or maybe not, since after that I may need to check for collision or something similar. Thinkig of it, seems like a silly question, but I would like some advice from more experienced developers. Where does does update ends and draw starts? Thanks in advance.

  • Best choice for 3D Physics Engine for C#/XNA

    - by Nic Foster
    Since 2007 I've been working on the development of an open-source game engine, and have been using JigLibX for 3D Physics. However, the developers on the project have stopped contributing to it for over 2 years now, and it's lacking features I need, or have major bugs in certain features. What are some good choices for 3D physics engines that are written purely in C#? Are there any that are more complete than JigLibX? EDIT: I just stumbled upon an engine called BEPUphysics. It was supported up until May 2012, which is fairly recent. I may check it out, any information that you guys could give on how complete the engine is would be great.

  • How to do fluid dynamics like “Where's My Water”?

    - by Edgar Miranda
    There is a game on the app store called "Where's My Water" that is really fun and uses fluid dynamics in its gameplay. You can check out a video of the gameplay... You use your finger to remove dirt from the screen, and then the water just flows to the new area. Anyone knows what engine this was made in and how they where able to get the fluid dynamics in there? I'm using the Corona SDK for mobile development and want to do something similar like this (a game with fluid dynamics).

If I counted correctly, there are 173(!) videos from this year’s conference, and a total of 467 videos from this and previous years. I’ve watched a lot of sessions from the major conferences that include .NET material, and NDC consistently has the best presentations in my opinion. There are lots of my favorite speakers: Crockford, Uncle Bob, Damian Edwards, Venkat Subramanian, Hanselman (I’m interested in seeing if he still thinks “poop” is funny, or got that out of his system at TechEd ;), Cory House (hey, KC!), the .NET Rocks Guys and more, so check it out!

  • How to choose, set and use keywords while structuring a website?

    - by mechdeveloper
    I have been working on my personal website for sometime, I think I have been doing a good technical job, but, unfortunately I did a terrible job while structuring the website because I didn't care about the keywords I was going to use. Although it is my personal website, I'd like to mention the main objective is the blog of the website, so I'd like that the keywords were related to the content that it is in the blog, at present google webmaster tools is displaying a lot of keywords that has nothing to do with the content of the website, and some SEO reporting websites such as woorank says that the keyword optimization of the website is awful, So I have 3 questions: How to choose, set and use keywords while structuring a website? OPTIONAL: which are all the methods and sources used by search engines to collect the keywords of a website? there are some high profile websites that aren't optimized on this as well, should I concerned about this anyway?, is there anything more important that I should be concerned about? (if you want to see the website please check my profile)

  • Unable to mount /dev/loop0 during install

    - by AJP
    I was installing 32-bit Ubuntu(ubuntu-10.10-desktop-i386.iso) on VMWare workstation 7.1. During installation an error came up with the following text. (initramfs) mount: mounting dev/loop0 on //filesystem.squashfs failed: Input/Output error Can not mount /dev/loop0 (/cdrom/casper/filesystem.squashfs) on //filesystem.squashfs I did a memory test which was successful, but when selecting "Try Ubuntu without installing", "Install Ubuntu" or "Check disk for defects" the same error is showing up. I download the ISO image from Ubuntu website "http://www.ubuntu.com/desktop/get-ubuntu/download". As I couldn't find the checksum data, the ISO image was verified by mounting to a virtual drive and browsing the contents. The ISO image is mounted to a virtual drive in VMWare and not burnt to a CD.

  • Can't mount external hard drive

    - by tezza
    i have a problem accessing the data on my external hard drive. I recently did a fresh install but mistakenly left my external hard drive plugged in. When I tried to access the data on the external HDD, it says "no files" but recognizes that there is 290 GiB of data on it. The HDD is 350GB big. I checked the drive with Disk Utility and it showed that the hard drive had a bootable flag. So, in the edit partition, I unchecked this bootablity. Now it won't mount in Ubuntu and now my XP can't recognize it at all, whereas I could access the data on the XP machine before. In disk utility, it doesn't give me the option to check the bootable box in again and I can't access the data on XP either. Any ideas on how to fix it?

  • New Bing Maps

    - by MikeParks
    Normally I don't stray too far from Programming and TFS on my blog posts but I'm just really impressed with how much Silverlight has improved Bing maps. I use to be big on MapQuest, then hopped over to Google, but now the new Bing Maps have everything I need. The two coolest features are right on the main page. All you have to do is go to http://www.bing.com/maps/explore/, enter your city and hit enter in the search box, then look in the lower left corner under the EXPLORE section. Check out the "What's nearby" and "Restaurants" links. The best part is, if you're interested in doing any Silverlight programming, they have a Bing Maps Silverlight Control Interactive SDK. I was thinking about coding something....but they've pretty much got it down :) Pretty impressive stuff.

  • How can I determine whether a shellscript runs as root or not?

    - by EvilPhoenix
    This is something I've been curious about. I make a lot of small bash scripts (.sh files) to do tasks that I routinely do. Some of those tasks require everything to be ran as superuser. I've been curious: Is it possible to, within the BASH script prior to everything being run, check if the script is being run as superuser, and if not, print a message saying You must be superuser to use this script, then subsequently terminate the script itself. The other side of that is I'd like to have the script run when the user is superuser, and not generate the error. Any ideas on coding (if statements, etc.) on how to execute the aforementioned?
