  • Can I use Ubuntu as a wireless media server which performs all decoding/processing server-side?

    - by AthloX
    I want to setup UBUNTU 12.04 desktop as Home media server. I have window 7 netbook and UBUNTU 12.04lts laptop even a samsun galaxy note tablet (android). Two desktop in other room with dualboot win7 and ubuntu. SHARP AQUOS Plasma Tv with Wi-Fi connected. I want to install ubuntu as media server to stream audio/video files over wi-fi. Not only this i want this media server to use its own processing power to decode ans stream so that on remote end only file can play without using their own resource. Is it possible to use ubuntu as media server to stream files without making the remote end to use there own resource. I want only bandwidth of Wi-Fi to be use in this and media center hardware resource.Remote end gadget should use only speaker and screen and not processing power of their own. Please any suggestion is it possible to do so ?

  • Removing mdadm array and converting to regular disks while preserving data

    - by Jeffrey Kevin Pry
    I have a 6 disk (2TB each) mdadm RAID 5 volume created in Ubuntu 12.04 Server. However, I'm moving to a different solution and want to "unraid" my disks but keep the data. Only 50% is in use. From what I can surmise I basically have to do this recursively for each physical disk. Fail the disk Format the failed disk Move a portion of files to the new disk. Reshape the array Shrink the logical volume md0 This seems like a very time consuming process. Is there an easier way to do this (automatically perhaps) without buying new disks to temporarily hold the data? I am also aware that during this processing my RAID volume will be degraded and vulnerable the entire time. I am not too concerned about this and will be using battery backup and moving the most important files off first. Thank you for your help!

  • Data Recovery using testDisk failing!

    - by iamcreasy
    I am trying to recover an accidentally formatted partition using testDisk, After selecting the partition[pic 1] and selecting Undeleted[pic 1], it says, No deleted file found.[pic 2] 1 2 I know it's a silly question, but I just want to make sure that those data are really out of reach. Or is there anything I can do to recover them? :( I tried to repair my partition table using bootrec.exe/FixMBR & bootrec.exe/FixBoot, can this be the reason why testdisk can't work anymore? I haven't written anything on that partition. Is there any low level approach to retrieve all the lost data?

  • Drawing different per-pixel data on the screen

    - by Amir Eldor
    I want to draw different per-pixel data on the screen, where each pixel has a specific value according to my needs. An example may be a random noise pattern where each pixel is randomly generated. I'm not sure what is the correct and fastest way to do this. Locking a texture/surface and manipulating the raw pixel data? How is this done in modern graphics programming? I'm currently trying to do this in Pygame but realized I will face the same problem if I go for C/SDL or OpenGL/DirectX.

  • How to ramp up my data structures skills after a long hibernation

    - by Anon
    I was pretty good with algorithms and data structures once, a long long time ago. Since then, I programmed professionally, and then went to manage a small team, which totally shot my tech skills in this field back. I've decided I want to be a developer again, and work for Google. The thing is, I'm so out of practice, that if I were to be interviewed right now I would surely flunk out in 10 minutes. What training program would you recommend for me to get back into shape? I already started this weekend by going back to the absolute basics and implementing a few sort algorithms, linked list, and hash table. Next, I think I'll read through the entire course material on the other basic data structures and graph algorithms. I want to find a focused set of practical exercises I can do in a relatively short amount of time, to juggle the old brain cells. I know this stuff - I just need to remind myself that I know it.

  • How to print over ssh?

    - by mit
    I have the following configuration: P == U ---------------- W P is a HP Laserjet, connected to U, which is an Ubuntu 10.04 desktop machine with a standard gnome setup from the live cd. I just selected the HP Laserjet in the gnome printer admin and it works, I can print locally. W is a remote windows machine, server 2003, and --- is an untrusted connection. I wonder if I can create an ssh tunnel between U and W, so W can print using U's printer service. Which ports will I need to forward and what kind of printer must I add then on the windows machine?

  • How to solve: "Connect to host some_hostname port 22: Connection timed out"

    - by Aufwind
    I have two Ubuntu machines. Both have openssh-client and openssh-server installed on them. ssh-ing from machine G (fresh Ubuntu 11.10 installation) to machine K works great. But ssh-ing from machine K to machine G results always in the Error: Connect to host some_hostname port 22: Connection timed out I went through the troubleshooting section of help.ubuntu.com and I got the following results: ps -A | grep sshd # results in 848 ? 00:00:00 sshd - sudo ss -lnp | grep sshd # results in 0 128 :::22 :::* users:(("sshd",848,4)) 0 128 *:22 *:* users:(("sshd",848,3)) - ssh -v localhost # works! - sudo ufw status verbose # yields: "Status: inactive" I haven't change anything in the config file. What can I do to locate the Problem and solve it? Glad about every hint! Edit: ping was succesful in both directions! I did a telnet <machineK> 22 from machin G which resulted in Trying and then in telnet: Unable to connect to remote host: Connection timed out. But telnet the other way around worked just fine! Edit 2: ssh start/running, process 966 # yields: ssh start/running, process 966 /etc/hostname # contains my hostname, let's call it blubb /etc/hosts # contains the following 127.0.0.1 localhost # 127.0.1.1 blubb 129.26.68.74 blubb # I added this! - sudo service ufw status # yields: ufw start/running I installed Gufw and set it to ON. Then I selected from Incoming the option ALLOW. Then I sshed to another machine from where I sshed back to my machine. Still the same error as above: connect to host blubb port 22: Connection timed out Any more hints, what I can check?

  • nagios3 Error: Could not read object configuration data!

    - by user1493730
    I have a brand new install of nagios3 on ubuntu 12.04. After I log in to the web interface and click any link I get the error: Error: Could not read object configuration data! Here are some things you should check in order to resolve this error: Verify configuration options using the -v command-line option to check for errors. Check the Nagios log file for messages relating to startup or status data errors. I ran it with the -v option and it reported no errors: Total Warnings: 0 Total Errors: 0 Things look okay - No serious problems were detected during the pre-flight check The nagios log and apache error log and debug log all have nothing regarding this. Does anyone know how to turn on logging that will give me some kind of useful error? Or if anyone knows how to fix this specific problem without additional logging, I guess that's okay too. Thanks!

  • Google Analytics Export API - nextPagePath data

    - by Btibert3
    I am probably missing something obvious, but I do not understand when I query: start.date = DATE_START, end.date = DATE_END, dimensions = c("ga:pagePath","ga:previousPagePath"), metrics = c("ga:pageviews"), filters = mypageofinterest, table.id = "ga:mytable", max.results=RESULTS my data return as expected, all of the previous pages including (entrance). However, when I modify the code to be nextPagePath start.date = DATE_START, end.date = DATE_END, dimensions = c("ga:pagePath","ga:nextPagePath"), metrics = c("ga:pageviews"), filters = mypageofinterest, table.id = "ga:mytable", max.results=RESULTS only one line of data are returned; the pagepath and nextpagepath are identical with itself. I replicated this result using the Query Explorer. What am I missing or doing wrong? I was expecting to see a large number of "next" pages, including (exit). Thanks in advance.

  • Skynet Big Data Demo Using Hexbug Spider Robot, Raspberry Pi, and Java SE Embedded (Part 4)

    - by hinkmond
    Here's the first sign of life of a Hexbug Spider Robot converted to become a Skynet Big Data model T-1. Yes, this is T-1 the precursor to the Cyberdyne Systems T-101 (and you know where that will lead to...) It is demonstrating a heartbeat using a simple Java SE Embedded program to drive it. See: Skynet Model T-1 Heartbeat It's alive!!! Well, almost alive. At least there's a pulse. We'll program more to its actions next, and then finally connect it to Skynet Big Data to do more advanced stuff, like hunt for Sara Connor. Java SE Embedded programming makes it simple to create the first model in the long line of T-XXX robots to take on the world. Raspberry Pi makes connecting it all together on one simple device, easy. Next post, I'll show how the wires are connected to drive the T-1 robot. Hinkmond

  • How to set Ubuntu as wireless accespoint in the GUI way?

    - by Agmenor
    My aim is to make my Ubuntu machine be a wireless accesspoint using wifi. Of course I found two AskUbuntu questions already treating that; this one and that one. Nevertheless, as far as I am concerned I would like to set up such a network in the Graphical User Interface (GUI) way. Please avoid solutions with the command line. So a solution suggesting to use Network Manager would be really welcomed. Please name and describe very precisely each step, so I can easily find the equivalent in my own language. Thank you for your answers!
