• How to control fan speed and temperatures on Asus A8Js laptop running Ubuntu Server?

  - by Azeworai

  Hi, I have tried installing asusfan and lm-sensors but I'm unable to control my fans to cool my laptop down sufficiently. Currently it overheats at about 100 degrees celsius and my sensors output somehow does not have any fan information on it: jackson@OLYMPIA:~$ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +69.0°C (crit = +110.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +66.0°C (high = +100.0°C, crit = +100.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +66.0°C (high = +100.0°C, crit = +100.0°C) I have checked my bios and there isn't any fan settings there. I can consistently overheat just by converting a video via Handbrake. I have ubuntu-desktop installed for a GUI. Is there a way for me to control my fans to start spinning before it reaches a critical temperature and kills itself?

• Why can't mythtv backend see my HDHomeRun tuner?

  - by Jeff

  Ran a fresh install of Mythbuntu 12.04.1 32 bit. Went through the backend setup and was able to see my HDHomeRun Prime (HDHR3) device, scan, and detect channels. Cannot get to live TV on frontend. Backend log seems to indicate it's not detecting my tuner, even though I configured it in the setup.

• How to Restrict Android App Permissions

  - by Chris Hoffman

  Android forces you to agree to every permission an app wants, assuming you want to use the app. After rooting your device, you can manage permissions on a per-app basis. Restricting permissions allows you to protect your contacts and other private data from apps that demand access you’d rather not allow. Many apps will continue working properly after you revoke the permissions. HTG Explains: What Is RSS and How Can I Benefit From Using It?

• Can only connect to file server on second attempt

  - by Ross Fleming

  I have a FreeNas file server on my local network and I usually connect to it from Windows and Ubuntu computers. Ever since I have upgraded from Ubuntu 12.04 to 12.10 Ubuntu will only connect after a second attempt. By which I mean, I will browse to it via the file manager and once I click on the link in "Bookmarks" it complains that it could not connect. If I then try again it connects successfully and will keep up it's connection until the laptop is suspended or looses connection to the LAN for whatever reason. This isn't much of a problem as I don't mind having to click twice but my real problem is that this means that my scheduled backup will complain that it cannot connect to the storage device if it has not already been accessed during the current session. If there is some way to either stop the issue all together or to force the backup tool (default) to immediately have a second attempt at connecting.

• Outline Shader Effect for Orthogonal Geometry in XNA

  - by Griffin

  I just recently started learning the art of shading, but I can't give an outline width to 2D, concave geometry when restrained to a single vertex/pixel shader technique (thanks to XNA). the shape I need to give an outline to has smooth, per-vertex coloring, as well as opacity. The outline, which has smooth, per-vertex coloring, variable width, and opacity cannot interfere with the original shape's colors. A pixel depth border detection algorithm won't work because pixel depth isn't a 3.0 semantic. expanding geometry / redrawing won't work because it interferes with the original shape's colors. I'm wondering if I can do something with the stencil/depth buffer outside of the shader functions since I have access to that through the graphics device. But I don't believe I'm able to manipulate actual values. How might I do this?

• How to Get the Folder Name of USB Disk?

  - by Kate Moss' Open Space

  When an USB Disk plugs into CE/Mobile based device, how do you know the folder name of the mounting point? Usually, it should be "USB Disk" but it is really depends on how OS image builder; they may change the folder name for whatever reason. FindFirstFlashCard looks simple and promising, the drawback is it only available on Windows Mobile. In fact, these find flash card API set will enumerate all of the mountable file system which includes SD card, CF and etc that we don't expect to get. So I am going to introduce you another way via Storage Manager. Here is the steps.

• After changing web host, I get a 'file does not exist' error

  - by Jordan

  I run a WordPress blog, and have recently changed web hosts. When changing web hosts, I copied all files and exported/imported the database etc as explained by lots of tutorials found easily on Google. The blog home page works fine. What goes wrong: When I click on any link from the home page, the browser gets stuck in a redirect loop. Looking at the error log, I see: File does not exist: /usr/local/apache/htdocs/index.php The directory /usr doesn't even exist for my website - so perhaps this is looking for a file that was present using my old Web Host and is no longer present with my new web host? What is going on, and how might I resolve it?

• What do you do when your naming convention clashes with your language?

  - by Jon Purdy

  Okay, this is one of those little things that always bugged me. I typically don't abbreviate identifiers, and the only time I use a short identifier (e.g., i) is for a tight loop. So it irritates me when I'm working in C++ and I have a variable that needs to be named operator or class and I have to work around it or use an abbreviation, because it ends up sticking out. Caveat: this may happen to me disproportionately often because I work a lot in programming language design, where domain objects may mirror concepts in the host language and inadvertently cause clashes. How would you deal with this? Abbreviate? (op) Misspell? (klass) Something else? (operator_)

• Developing a computer system based on Nand2Tetris [on hold]

  - by Ryan

  I recently finished a book called Nand2Tetris (nand2tetris.org) where I built my own computer system from scratch with its own machine language, assembly code, and a high level language called Jack that's translated to Hack binary. However, I feel like the "computer" I built throughout the course of this book (called the Hack computer) is a bit too simple for various reasons: 1) There are only two registers (D and A), whereas most computers have much more 2) Peripheral devices like mouse and keyboard have to be directly implemented 3) Peripheral devices use a pre-planned shared memory map to communicate with the CPU instead of using interrupts (which aren't covered at all) 4) Jack (the high level language) code doesn't compile to Assembly code directly, instead it compiles to an intermediate language, which in turn gets translated to Assembly. 5) There is no ROM or permanent storage device, everything is stored in RAM 6) No support for colored monitor, networking or sound I would like to build a more complicated computer system now based on what I've learned from Nand2Tetris. Does anyone know of any good resources or books to get started on this? (BTW by computer system I mean software that can emulate the hardware of a virtual computer with its own unique instruction set)

• USB modem could not mount on 12.04

  - by maz

  I have a usb wimax modem. If I connect it at ubuntu 10.04 it has been detected and mounted as cd see here. From there I got that it is "iso96660" type and device location is /dev/sr1. But when I connect this usb modem in Ubuntu 12.04, it could not be mounted. So I have tried to find the file sr1 in this location /dev/ and could not found any-thing. But if disconnect and then re-connect the usb modem at this path /dev/, I saw a flickering of "sr1" named file for a certain time (1 sec) then it's dis-appear. Can anyone guide me to connect it step-by-step in Ubuntu 12.04?

• Best way to redirect users back to the pretty URL who land on the _escaped_fragment_ one?

  - by Ryan

  I am working on an AJAX site and have successfully implemented Google's AJAX recommendation by creating _escape_fragment_ versions of each page for it to index. Thus each page has 2 URLs: pretty: example.com#!blog ugly: example.com?_escaped_fragment_=blog However, I have noticed in my analytics that some users are arriving on the site via the "ugly" URL and am looking for a clean way to redirect them to the pretty URL without impacting Google's ability to index the site. I have considered using a 301 redirect in the head but fear that Googlebot might try to follow it and end up in an endless loop. I have also considered using a JavaScript redirect that Googlebot wouldn't execute but fear that Google may interpret this as cloaking and penalize the website. Is there a good, clean, acceptable way to redirect real users away from the ugly URL if for some reason or another they end up arriving at the site that way?

• design for a parser to handle very large files

  - by user619818

  I have written a program which records protocol messages between an application and a hardware device which matches each application request with each hardware response. This is so that I can later remove the hardware, connect a 'replay' application to the main application and wait for an application request and reply with a matched copy of the requisite hardware reply message. My replay application saves the matched request/response in a list (using C++ std::list). This works fine on a small interaction session. My problem now is that I need to be able to use the replay over a long long session. With my current implementation, the replay program eventually uses up all available memory on my computer and crashes. So I need some sort of lookahead - and not parse the whole session in one go. Can anyone make any suggestions on how to get started?

• Where is Nautilus icon file located and how is it chosen?

  - by Steve

  When I plug my Garmin Nuvi 265 GPS device into my computer via a USB cable, it mounts as a drive with a blue triangle icon instead of the default gray hard drive icon. HOW does Nautilus know how to do this? After much laborious searching, I found that the icon info is stored in ~/.gconf/apps/nautilus/desktop-metadata/GARMIN@46@volume/gconf.xml -- but only when a custom icon is selected. So Where is this blue icon file? Why does Nautilus use it instead of the plain drive icon? Is there a way to have give each of my drives a custom icon -- so that when I stick in my various flash drives, they have a distinctive icon (i.e. a 'favicon.ico' file on root or such?) Using Gnome 2.30.2 on Ubuntu 10.04.

• How do I rename a mounted Truecrypt volume?

  - by invert

  When I mount the Truecrypt file on my USB drive it shows up as truecrypt1. The volume is FAT, using mtools to rename a volume label involves e2label /dev/sdbx, however truecrypt1 does not map to a physical partition. fdisk -l does not show the volume partition (only the physical USB device), and df -h lists the volume path as /dev/mapper/truecrypt1. Finally, using the Nautilus 'Rename' context action, gives the error: "Sorry, could not rename "truecrypt1" to "towel": Operation not supported by backend". Apparently this can be done in Win, but how can I rename this volume in Ubuntu? As Nicolas said, specifying the mount point names the partition the same. The truecrypt GUI does not remember the mount point I set, so I specify the mount points in a script which I placed in my main menu. #!/bin/bash gksudo truecrypt /media/usbdrive/encryptedfile /media/securedata/

• How to Disable or Uninstall Android Bloatware

  - by Chris Hoffman

  Manufacturers and carriers often load Android phones with their own apps. If you don’t use them, they just clutter your system and sometimes in the background, draining resources. Take control of your device and stop the bloatware. We’ll be focusing on disabling – also known as “freezing” bloatware here. It’s a safer process than uninstalling the bloatware completely, and is also easier to accomplish with free apps.

• creating a list of consecutive integers in c#

• KDE's Dolphin Can't See Connected devices such as Nikon, Canon Cameras

  I have noticed this problem across all distros including Kubuntu and openSUSE. Many times my Nikon D 7000 and Canon HF 11 are not seen or mounted by Dolphin. When I connect the Cameras I don't get any notification in the tray which otherwise shows connected device. Ironically when I open Nautilus then I can clearly see the cameras mounted. I also have a request that what these devices don't appear on Dolphin's side panel automatically. It makes life easier for a users. https://bugs.launchpad.net/ubuntu/+source/dolphin/+bug/956806/+attachment/2879913/+files/dolphin.png

• How to correctly create a virtual file system?

  - by Paul

  A task in my homework assignment asks me to create a virtual file system, mount it, and perform some operations on it. I am supposed to create a file of 10 MB whose bits are all set to 0, format it as ext3 and mount it. This is how I've done that: dd if=/dev/zero of=~/filesyst bs=10485760 count=1 sudo mkfs.ext3 ~/filesyst sudo mount –o loop ~/filesyst /media/fuse Even though I've used /dev/sero, the file i still full of gibberish characters (mostly at-signs). The permissions on /media/fuse are drw-rw-rw- (which are alright), but the permissions on the files inside it are something like this: d????????? ? ? ? ? ? lost+found -????????? ? ? ? ? ? secret_bin Where have I gone wrong?
