• Only recognizes one partition from multi partitions SD card

  - by Jay Ngo

  Hello everybody, I split my sd card into 2 partitions. When i use usb-card-reader to read my sd card, only the one partition shows up on the screen, the other doesn't. I have run the command "sudo fdisk -l" and the result is the same, only one partition is recognized. But i do believe both partitions of my sd card work fine, because i still can boot my single-board computer with that sd card and run some programms, which are inside that unreadable partition. How can i access both partitions of my sd card? Does anyone know how to solve this kind of problem? I really appreciate your help.

• Computer Boot/Installation Failure

  - by Marcus

  I recently tried to insatll Kubuntu and it failed. It completely removed everything off of my HDD and there is no operating system. Everytime I try to install a Distro it fails during instillation. I got Ubuntu 13.04 to work but it required a reboot and after that it did not work. I tried to re-install Ubuntu but it failed. I have tried Ubuntu, Kubuntu, and Xubuntu and they all failed. With Kubuntu and Xubuntu I get an error saying, "The 'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot". When I select try (distro) it loads up but the installation won't finish. I do not want to have to try the distro everytime I want to get on it. Any help?

• CreateRenderTarget returns 0x80070057 in big surface resolution

  - by senggen

  I have created the SLI merged desktop of three 1920x1680 monitors, so the desktop resolution is 5760x1080. There is a 0x80070057 error, while calling CreateRenderTarget to create the RT_Surface: IDirect3DSurface9* _render_surface; HRESULT hr = _device->CreateRenderTarget( _desktop_width * 2, _desktop_height + 1, D3DFMT_A8R8G8B8, D3DMULTISAMPLE_NONE, 0, TRUE, &_render_surface, NULL); It works OK with desktop resolution 1024x768, and the total resolution is 3072x768.

• Corona SDK: Animation takes a long time to play after "prepare" step

  - by Michael Taufen

  First off, I'm using the current publicly available build, version 2011.704 I'm building a platformer, and have a character that runs along and jumps when the screen is tapped. While jumping, the animation code has him assume a svelte jumping pose, and upon the detection of a collision with the ground, he returns to running. All of this happens. The problem is that there is this strange gap of time, about 1/2 a second by the feel of it, where my character sits on the first frame of the run animation after landing, before it actually starts playing. This leads me to believe that the problem is somewhere between the "prepare" step of loading up a sprite set's animation sequence and the "play" step. Thanks in advance for any help :). My code for when my character lands is as follows: local function collisionHandler ( event ) if (event.object1.myName == "character") and (event.object2.type == "terrain") then inAir = false characterInstance:prepare( "run" ) -- TODO: time between prepare and play is curiously long... characterInstance:play() end end

• Max Degree of Parallelism Server-Side Setting

  - by Tara Kizer

  Recently I opened a case with Microsoft PSS to help us through a severe performance problem on a new system.  As part of that case, the PSS engineer checked our “max degree of parallelism” server-side setting.  It is our standard to use 4 on our production systems that have 16 CPUs (2 sockets, quad-core, hyper-threaded).  The PSS engineer had me run the below query to get Microsoft’s recommended value of “max degree of parallelism” server-side setting for our 16-CPU system: select case when cpu_count / hyperthread_ratio > 8 then 8 else cpu_count / hyperthread_ratio end as optimal_maxdop_setting from sys.dm_os_sys_info; The query returned 2.  I made the change using sp_configure, and it did not resolve our issue.  We have decided to leave it in place for now.   Do you agree with this query?  What are your thoughts on this? If you decide to change your setting to reflect the output of this query, please test it first to ensure there are no negative side effects.

• What are the most common AI systems implemented in Tower Defense Games

  - by the_Dan

  I'm currently in the middle of researching on the various types of AI techniques used in tower defense type games. If someone could be help me in understanding the different types of techniques and their associated advantages. Using Google I already found several techniques. Random Map traversal Path finding e.g. Cost based Traversing Algorithms i.e. A* I have already found a great answer to this type of question with the below link, but I feel that this answer is tailored to FPS. If anyone could add to this and make it specific to tower defense games then I would be truly great-full. How is AI most commonly implemented in popular games? Example of such games would be: Radiant Defense Plant Vs Zombies - Not truly Intelligent, but there must be an AI system used right? Field Runners Edit: After further research I found an interesting book that may be useful: http://www.amazon.com/dp/0123747317/?tag=stackoverfl08-20

• favored keyboard layout keeps being replaced

  - by Johannes Bauer

  My Ubuntu was installed with only a German keyboard layout configured. I much prefer the English UK (extended WinKeys) layout and therefore added that option. However, the selected keyboard layout kept reverting to German seemingly at random, and so I removed it through the layout indicator's preferences dialog. Strangely that didn't help: every now and then the English keyboard layout is replaced by the German one and that change shows up in the layout indicator. I guess the unwanted layout must still be configured somewhere and I must be hitting some key combination to switch to it. But the preferences dialog for the layout indicator doesn't show any such combination. I'm on Ubuntu 12.04 and I'm using Xfce 4.8. PS: This is similar but not the same as this or this issue: when I log in, the correct layout is usually selected (and only that layout is configured). The layout is changed completely at random while I'm working.

• Aser Aspire 3690 WIreless Not working, new Ubuntu user

  - by drew

  I don't know that much about Ubuntu, but I put it on an Acer Aspire 3690 Laptop (replaced Win Vista). Everything seems to work fine, but the wireless connection. It says "FIRMWARE MISSING". It detects that I have a wireless card, so I don't know what to do. I've already used the "ADDITIONAL DRIVERS" thing, and that didn't work. I've googled and have not found anything helpful. I don't really know what I'm doing, so can your directions please be kindergarden level? Thank you very much for any help you can provide. I really appreciate it.

• What should I learn to create web-services like ones listed? [closed]

  - by Gerald Blizz

  I am very inspired by websites like imgur, dropbox, screencloud, maybe w3schools...you get my point. Fresh web-services with some new idea, not big portals but something simple yet useful and used by many people, something simple and new. What aspects of my developer career should I focus to be able to build such things on my own if I have enough ideas? (Sure if it ends up being popular I can get more developers to help me and so on, but at first I can do it alone, right?) I am currently a PHP web-developer, I know HTML+CSS+JS+AJAX+JQuery. But even like that there still is web-design, there are a lot of paths: websites for enterprise, startups, webservices, entertainment websites and serious bank/document flow systems, frameworks used for big systems, different approaches for little ones, etcetcetc. Which path should I take to be able to start my own projects like the ones that I listed on top which inspire me?

• Sound distortion in Ubuntu 14.04

  - by Aditya Shah

  I recently installed Ubuntu 14.04 on my Dell XPS 15 (L502X). Previously I had Ubuntu 12.04 installed on the laptop along with Windows 8.1 dual boot. The sound worked perfectly fine in Ubuntu 12.04 and is working fine in Windows 8.1. Of late, I have been experiencing sound distortion coming from the subwoofer at moderately high volume levels. At the same level I am unable to reproduce the same effect in Windows 8.1. Also, I did a clean install of Ubuntu 14.04 over 12.04. Can anyone please confirm this and help me with this? Thanks

• How to explain to a layperson the variance in programmer rates?

  - by Matt McCormick

  I recently talked to a guy that is looking for developers to build a product idea. He mentioned he has received interest from people but the rates have varied from $20-120/hr. This project he estimates should take 3-6 months and since he is non-technical, he is confused why there can be so much variance. I understand how I would choose someone but I am a developer and can gauge other people's work. How can I explain to him (in a non-biased way, if possible, as I will apply as well) about the variance in rates? Is there any good analogy that would help?

• ATI Radeon HD 5750 and lagging in games and youtube videos

  - by Morten Fjord Christensen

  I have a X-ONE W-601 desktop pc: 3,1GHz AMD QuadCore Athlon II 645 X4 8 GB DDR3 RAM 1000 GB Harddisk 7200RPM ATI Radeon HD5750 with 1GB DDR5 RAM I'm running Ubuntu 11.10 64-bit and have installed the proprietary driver, but still games lag and videos a little bit. Been googling around and seen that it has something to do with the older drivers from AMD and KMS, but no guide helped me correctly through to make my graphic card work smoothly. I don't know if this helps but "fglrxinfo" in terminal shows: display: :0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI Radeon HD 5700 Series OpenGL version string: 4.1.11005 Compatibility Profile Context And the driver check command shows: [ 51.184] (II) ATI Proprietary Linux Driver Version Identifier:8.88.7 Any help appreciated :D

• Do employers prefer software engineering over CS majors?

  - by Joey Green

  I'm in grad school at a university that was one of the first to have a software engineering accredited program. My undergrad is in CS. An employer recently recruited at our university and hired 5 SE majors. None of them were CS. Do employers prefer software engineering majors? The reason I ask is because I can focus on many different areas during my graduate studies and really want to take the classes that will help me land a great job. Right now I'm either going to use CUDA and parallelize an advanced ray-tracer for a graduate project or do research on non-photo-realistic rendering in augmented reality. Pursuing these would leave very little SE classes in my schedule. If I went the software engineering route, I would probably either do research into data-oriented programming or software design complexity. Sometimes I think when I'm 40 and look back will it matter at all? For some reason I'm thinking not.

• Slow DNS Resolution

  - by user4541

  After a clean install of 10.10 I'm finding DNS resolution takes quite a long time. Hitting any url takes a good few seconds (10 - 30) before the site is displayed. I'm thinking this is a DNS resolution issue due to the 'waiting' or 'looking up' text being displayed in Firefox and Chrome. I do not get this issue with Slackware Linux or Windows 7 so it is not network or DNS server specific issue. It's something on the client side. Looking around on Google I see there are a few other people with this issue. The ones that have reported a workaround by switching to openDNS are disabling IPV6 or dealing with another issue. Any help would be appreciated. My network card is wired: Broadcom Corporation NetLink BCM5906M Fast Ethernet PCI Express Thanks

• Object Oriented programming on 8-bit MCU Case Study

  - by Calvin Grier

  I see that there's a lot of questions related to OO Programming here. I'm actually trying to find a specific resource related to embedded OO approaches for an 8 bit MCU. Several years back (maybe 6) I was looking for material related to Object Oriented programming for resource constrained 8051 microprocessors. I found an article/website with a case history of a design group that used a very small RAM part, and implemented many Object based constructs during their C design and development. I believe it was an 8051. The project was a success, and managed to stay inside the very small ROM/RAM they had available. I'm attempting to find it again, but Google can't locate it. The article was well written, and recommended a "mixed" approach using C methods for inheritance and encapsulation - if I recall correctly. Can anyone help me locate this article?

• Remapping Shift Selection in Gnome Terminal

  - by Gowie47

  Hey so I was hoping somebody could help me out in finding a way to get shift-selection working in gnome-terminal on Ubuntu 11.10. I found the question/bug report below but neither seem to have a solution. I use Emacs for development and being able to select my current line with shift-ctrl-a/e is something I find myself trying to do every couple of minutes. I use 10.04 at work and this is possible so I am not sure what has changed. If it matters I am using Gnome 3 Shell and I use bashish to style my terminal. Thanks in advance! https://bugs.launchpad.net/ubuntu/+source/vte/+bug/546021 http://askubuntu.com/questions/31991/using-the-shift-key-in-terminal

• Browser window size statistics?

  - by Litso

  Hey all, I was wondering, are there any statistics available on what size users have their browser set to nowadays? I know the screen resolutions (we have analytics, which shows those as well) but I doubt a lot of people with 1280*xxx and higher still browse full-screen though. My boss is determined to keep our website 900px wide though, because that way people with 1800*xxx resolutions can have two browser windows next to eachother without having to scroll horizontally. I have never seen anyone browse with two adjacent browser windows like that except here at my current job, so I'm kind of doubting whether this is the best decision or just his personal preference. Anyone that can help out here?

• Why isn't Grub2 using custom resolution?

  - by beanaroo

  I hope somebody can help me with this... Running Ubuntu 12.10 I am trying to get Grub2 to use a resolution of 1600x900... I have checked vbeinfo and hwinfo --framebuffer which both provide: Mode 0x037f: 1600x900 (+6400), 24 bits This resolution has worked on previous Ubuntu and Fedora installs. Here is my /etc/default/grub: http://paste.ubuntu.com/1308444/ Line 25 = GRUB_GFXMODE="1600x900" As well as my /boot/grub/grub.cfg: http://paste.ubuntu.com/1308446/ Line 72 = set gfxmode=1600x900 I have tried using grub-customizer: Why is it not taking effect?? I have tried different resolutions... Backgrounds and font colours are changeable. Thank you for your insight.

• Fundamental programming book [closed]

  - by Luke Annison

  I'm a fairly new programmer and currently learning ruby on rails with the intention of developing a web application. I am currently going reading Agile Web Development with Rails 4th Edition and its working well for me, however I'm wondering if somebody can recommend a more general, almost classic book to read casually alongside to help cement the fundamentals in place. As I said, I'm for the most part a beginner and the only education I've had is this and briefly one other technical book, so I'm sure there must be some "must reads" out there that give me a more substantial context for the basics of either Ruby on Rails, Ruby, objective oriented programming, or programming in general. What books helped you grasp a deeper and more rounded understanding of your skills as a programmer? All suggestions are welcome and appreciated.

• Windows 8 fresh install and 12.10 dual boot

  - by Sir Linuxalot

  I have a question concerning Windows 8 and dual booting with Ubuntu 12.10. I've researched answers here, but haven't seen a question that resembles mine exactly: Ubuntu install and dual Boot with Windows 8 UEFI UEFI hardware and dual booting with windows Ubuntu 12.10 wont boot Specifically, I'm pondering installing a fresh install of Windows 8 (for game purposes), and a fresh install of 12.10 and dual booting them. I'm not sure if UEFI is hardware specific or software specific, and I'm worried if I try to implement the dual boot I'm going to run into UEFI issues and have to go through the grief of getting things up and running by following a long and tedious procedure. Can I, starting with Windows 8, then install 12.10 without too much hassle? My current hardware config is: Microstar Motherboard 7514 with an Intel Core 2 Duo processor. The drive I'm thinking of using is a Western Digital TB drive, new out of the box. As always, any help would be appreciated. Thanks.
