• 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?

• Cocos2d update leaking memory

  - by Andrey Chernukha

  I have a weird issue - my app is leaking memory on device only, not on a simulator. It is leaking if i schedule update method anywhere, on any scene. It is leaking despite update method is empty, there's nothing inside it except NSLog. How can it be? I have even scheduled update on the very first scene where it seems there's nothing to leak, and scheduled another empty and it's leaking or not leaking but allocating something, the result is the same - the volume of the memory consumed is increasing and my app is crashing soon. I can detect the leakage via using Instruments-Memory-Activity Monitor or with help of following function: void report_memory(void) { struct task_basic_info info; mach_msg_type_number_t size = sizeof(info); kern_return_t kerr = task_info(mach_task_self(), TASK_BASIC_INFO, (task_info_t)&info, &size); if( kerr == KERN_SUCCESS ) { NSLog(@"Memory in use (in bytes): %u", info.resident_size); } else { NSLog(@"Error with task_info(): %s", mach_error_string(kerr)); } } Can anyone explain me what's going on?

• How do I plot individual pixels using the XNA APIs?

  - by izb

  If I wanted to fill my game screen with individually coloured pixels, how would I do this? For example, if I wanted to write a 'game of life'-type game where each pixel was a cell, how would I achieve this using XNA? I've tried just calling SetData() on a Texture2D object using a screen-sized array of Color values, but it complains with: You may not call SetData on a resource while it is actively set on the GraphicsDevice. Unset it from the device before calling SetData. How do I do as it asks? Or better still... is there an alternative, better, efficient way to fill a screen with arbitrary pixels?

• Ubuntu 10.10 USB drive not showing

  - by Ben

  USB is detecting but not showing the drives or mount details. Nothing there inside my /media folder and /mnt folder. I already enabled automatic mount and give privilege to user also.

• Ubuntu doesn't find hdds with higher clock rates

  - by user136243

  I dual boot windows 7 64-bit and ubuntu 13.10 64-bit on separate disks, and utilize some overclocking from the BIOS. Windows works fine, however ubuntu can't seem to find any hard drives, except for at stock cpu speeds. While attempting to boot it says Gave up waiting for root device... and ALERT! /dev/sdb7 does not exist. Dropping to shell! A bootable usb stick still works, but gparted doesn't detect any other drives. Have tried: Boot-repair Changing SATA mode in BIOS Newer kernels Older ubuntu versions Not sure it's relevant, but the motherboard is a Gigabyte GA-A75M-UD2H with the newest BIOS version, the CPU an AMD Llano. This is hardly a fatal error, but it's inconvenient to change BIOS settings whenever I want to switch OS, and furthermore I'm quite curious about why it won't work. I'd appreciate any insight into what the actual problem is. So how can I resolve this issue ?

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

  - by Swapnil

  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

• What does a media server need?

  - by DeaDSouL

  I want to buy a new PC to be used as a media server that streams HD movies, music to any wireless device on my network (laptop, desktop, TV, etc.). I was wondering about the PC hardware's specifications that I need to have so that it can work just fine? (It will be wireless) Is there any tutorial showing how it could be done? And the security - how can I secure it? As well as I need it to to host my emails. I mean I have many emails. And sometimes I'm using desktop, sometimes laptop.. so is it possible to make the server store a copy of my emails, attachments, all sent items (whether they were from desktop or laptop)?

• Control external monitor brightness

  - by remi

  Hello Ubuntu community, I can control the brightness of my DELL U2713HM connected with DisplayPort via the command: ddccontrol -p -r 0x10 -w 53 where in this example the number 53 represents the brightness level (range 0 to 100). But I don't know how to link the command to my brightness keys on my keyboard. I searched already, but just found answers to integrated laptop screens. In /sys/class/backlight is the folder acpi_video0 with some subfolders and files. The file actual_brightness contains a number from 0 to 20, which is changing when I press the brightness keys. How do I get my external monitor listed as a device in /sys/class/backlight ? PS: I am running a fresh Ubuntu 12.10 install with integrated graphics Intel HD4000.

• Is there a size limit when using UICollectionView as tiled map for iOS game?

  - by Alexander Winn

  I'm working on a turn-based strategy game for iOS, (picture Civilization 2 as an example), and I'm considering using a UICollectionView as my game map. Each cell would be a tile, and I could use the "didSelectCell" method to handle player interaction with each tile. Here's my question: I know that UICollectionViewCells are dequeued and reused by the OS, so does that mean that the map could support an effectively infinitely-large map, so long as only a few cells are onscreen at a time? However many cells were onscreen would be held in memory, and obviously the data source would take up some memory, but would my offscreen map be limited to a certain size or could it be enormous so long as the number of cells visible at any one time wasn't too much for the device to handle? Basically, is there any memory weight to offscreen cells, or do only visible cells have any impact?

• If an app runs well on iPhone 3GS with iOS 5.1, how to know that it runs well on iOS 4.3? [closed]

  - by ????

  I bought an iPhone 3GS just to test backward compatibility of apps that I developed, but it arrived preinstalled with iOS 5.1. So even if an app runs well on iPhone 3GS and iOS 5.1 with its hardware limitation, how can we tell that it runs well even on iPhone 3GS with iOS 4.3? Will it actually be better to install iOS 4.3 on the phone so that we know even the older iOS can support it, so the newer iOS will work well supposedly? Or is there a need to buy yet another iPhone 3GS and install 4.3 on one and 5.1 on the other? (my assumption is that if we set the app's build target iOS to 4.3, the iPhone 3G won't be able to install it, because iPhone 3G only runs iOS up to 4.2. So the target device is 3GS but not earlier. But it will exclude iPod Touch 2nd Generation as well because they also can only support iOS up to 4.2 only)

• 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/

• Banshee won't sync OGG format to my iphone

  - by Daze

  I have a jailbroken iphone 3g with 16 gigs of memory and I've been putting my music on it from banshee lately and have been having almost no issue. Unfortunately, I just added a few albums to my Banshee library and tried to sync them to my iphone, but every time I try, i see a hundred or so errors saying that the device doesn't support the ogg format and there was no converter found. I'm still pretty much a newb at this stuff, so please help me and dumb down your answer. I'm running 12.04 and again, using an iphone 3g with no sim card, but it's been jailbroken and is used primarily for it's music function.

• How do you maintain content size vs. content quality in a mobile application?

  - by PeterK

  I am developing my first Cocos2d iPhone/iPad game that includes quite a few sprites, I would need approximately 80 different. As this is for both normal and HD displays I have 2x of each sprite. I am using TexturePacker to optimize the thing. I would like to ask if there are any rules-of-thumb, tricks, ideas etc. to adjust to in regards to size of content, quality and how you maintain high-quality HD-based graphics due to its size vs. the device memory sizes? Also, is it a good idea to only have one copy of the sprites and scale it using code?

• How To Use USB Drives With the Nexus 7 and Other Android Devices

  The Nexus 7 may not have a lot of storage space – especially the original 8 GB model – but you can connect a USB drive to it if you want to watch videos or access other files. Unfortunately, Android doesn’t automatically mount USB drives by default. You’ll need to root your device to enable support for USB drives.

• Sound coming out of headphone when running Ubuntu, but not window 7

  - by MrSimon

  I've downloaded Ubuntu yesterday, and I thought that everything went smoothly, until I found out a problem today. When I am running the Ubuntu OS on my laptop, the Samsung RC420, the speaker and the headphone works fine. However, when I am running the Window 7 OS, the speaker works fine, but my headphone will not emit any sound although the laptop has detected that 'a device has been plugged into the audio jack'. The same problem persist when I connect my X-minis as well. I tried updating my sound card drivers, check if they are hidden/disabled/disconnected and everything else. Nothing works :(

• 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)

• Remove encryption from USB flash drive

  - by Timic

  It all started when I was attempting to format my PNY USB drive because it was full of junk. When it asked me what type of file system, I selected FAT but there was a checkbox below that said "Encrypt" and I accidently checked it and continue. I had no choice but to come up with a passphrase for it, and so I did, thinking I was able to remove that encryption. But after that at Disk Utility I thought I would find a "Remove Encryption" button or something like that but I didn't. I tried formatting it to remove the encryption but it gives me an error: Error Formatting, The device is busy" Detail>>> One or more block devices are holding /dev/sdb/. I am stuck, what should I do?

• Windows Not Sleeping All Night

  - by John Paul Cook

  Having a computer wake up when you don’t want it to wastes electricity and drains the battery on mobile devices. My desktop had been waking up at night, so I assumed it was some network traffic on my home network. I unchecked Allow this device to wake the computer on my network adapters . Figure 1. Network adapter Power Management tab. That didn’t solve the problem. I included the screen capture in Figure 1 because it could be part of the solution for someone else.

• Android opengles 2.0 :different resolutions rendering and input

  - by kkan

  I'm currently developing a sprite based 2D game for android using opengles 2.0. I've got some basic rendering done that mimics the spritebatch functionality of xna (draw sprite, rotation, color). But all of this works for a fixed projection matrix, but android has a lot of screen sizes. Q1)Would this be an okay method to scale up/down the drawing? 1)Draw the whole screen to a texture. 2)Draw the above texture as a quad to the device. I found the above through some searching, not sure if it's the best one, are there any alternatives? Q2)How do you handle inputs for different resolutions? I currently get the position of a touch and use it raw. Would it be okay to get the position, and then scale the position to size of the texture used for rendering, and the perform calculations on it? Thanks.
