• How can I get shockwave flash to work on Ubuntu 12.04

  - by John Hill

  I've tried most of the things suggested on this site and others so far. It's kind of frustrating because this is a home computer and I mainly use it for browsing the internet and watching YouTube videos. When I try to install something that might fix it, it just downloads a bunch of files and says to extract them or whatever. I'm not sure what to do with the files after I extract them. That's probably the main issue: I don't have a lot of experience working with computers at this level. I'm used to Windows, which seems to make most software installs idiot-proof. Any suggestions are appreciated!!

• Benchmarking CPU processing power

  - by Federico Zancan

  Provided that many tools for computers benchmarking are available already, I'd like to write my own, starting with processing power measurement. I'd like to write it in C under Linux, but other language alternatives are welcome. I thought starting from floating point operations per second, but it is just a hint. I also thought it'd be correct to keep track of CPU number of cores, RAM amount and the like, to more consistently associate results with CPU architecture. How would you proceed to the task of measuring CPU computing power? And on top of that: I would worry about a properly minimum workload induced by concurrently running services; is it correct to run benchmarking as a standalone (and possibly avulsed from the OS environment) process?

• How to enable true remote login

  - by Scán

  I don't quite know how these things are called, so a search did not product any help. I've got two computers, a desktop and a netbook. The netbook is really weak, and there's hardly any fun doing work with it, especially after ubuntu software swallows so much cpu power for nothing. But my desktop is good, but uncomfortably positioned. So I know you can use any linux system as a server to give logins. I want to be able to login and work on my desktop, from my netbook. No VNC, no SSH, full X-server, I want to be able to choose "Login on Desktop" in my login menu on the netbook and have everything as if I was there. I hope I could make my point. Is it possible in a local network? And if so, how can I easily set it up?

• Literature in programming and computer science

  - by Peter Turner

  I hope, gentle programmers, that you'll forgive me for not asking a "Soft Question" on theoreticalCS.SE and asking this here. It has recently come to my attention that bigendian came from Jonathan Swift's Gulliver's Travels. I was pretty surprised when listening to the book on my commute to hear something I'd only heard before in Comp Sci / Engineering classes. I thought it was some sort of nouveau-politically incorrect piece of holdover jargon like Master and Slave drives or Polish Notation. Are there any other incidents, not of politically incorrect jargon, but of literature influencing aspects of computers, programming or software development?

• Slow internet browsing in Ubuntu

  - by Mark

  I have a dual boot set up with windows and ubuntu, when I'm using windows internet browsing is a lot faster than when I'm using ubuntu and I don't know why. It's like there's just a big latency rather than the maximum speed is lower, there's a big delay before anything happens when using Ubuntu, it happens with all websites all the time. I've never configured the internet connection because it just worked straight away. I have broadband connection through a router shared with some other computers, when we set up the router and internet connection everything was done with windows. Any ideas on what I could do to fix this? Thanks to anyone who replies.

• Global menu not showing in Ubuntu 12.10 with Unity

  - by William

  I am on Ubuntu 12.10 with Unity shell. I am not quite sure what happened, but today I noticed that the menubar (containing 'File, Edit, etc...') is not appearing on the panel as it used to (i.e. the global application menu), but on the application window under the title bar. The only application that still uses global menu is Chromium. Any ideas what settings may have changed? Also, when I right click on the desktop and select "Change Desktop Background", System Settings opens, instead of the "Appearance" settings. Apparently, here is a related question, with no answer: Global menu and HUD suddenly broken EDIT: I noticed this behavior on three of my computers after an update (I do not remember exactly which packages were updated). Now when I try to run apt-get upgrade, I get: The following packages have been kept back: gnome-control-center gnome-control-center-data I guess something is going on with updates. Any info would be appreciated.

• What You Said: How You Customize Your Computer

  - by Jason Fitzpatrick

  Earlier this week we asked you to share the ways you customize your computing experience. You sounded off in the comments and we rounded up your tips and tricks to share. Read on to see how your fellow personalize their computers. It would seem the first stop on just about everyone’s customization route is stripping away the bloat/crapware. Lisa Wang writes: Depending on how much time I have when I receive my new machine,I might do the following in a few batches, starting with the simplest one. Usually, my list goes like this:1.Remove all bloatware and pretty much unneeded stuffs.2.Change my wallpaper,login screen,themes, and sound.3.Installing my ‘must-have’ softwares-starting with fences and rocketdock+stacks plugin4.Setting taskbar to autohide, pinning some apps there5.Installing additional languages6.Tweaking all settings and keyboard shortcuts to my preferance7.Changing the icons(either manual or with TuneUp Styler) Interface tweaks like the aforementioned Fences and Rocket Dock made quite a few appearances, as did Rainmeter.

• Acer Aspire One 722 broadcom 4313 wifi

  - by Colin Matheson

  I had an Acer Aspire One 722 with the Atheros Wifi card and it worked fine on 11.04. So we bought 200 of them for our school. However these all came with the Broadcom BCM4313 wireless card and there are issues. It is using the brcmsmac driver and they connect initially. However after a time (sometimes just a few webpages) some of them lose connection. However, they still have an IP and network-manager says they are connected, but no pages load and you can't ping anything on the LAN or internet. A disconnect/reconnect can fix it, but sometimes a restart is required. It happens frequently so is a major issue. Lots of broadcom drivers are blacklisted: bcm43xx, b43, brcm80211. Any ideas or experiences with the broadcom4313 card? Please save these computers from a Windows fate!

• How often do CPUs make calculation errors?

  - by veryfoolish

  In Dijkstra's Notes on Structured Programming he talks a lot about the provability of computer programs as abstract entities. As a corollary, he remarks how testing isn't enough. E.g., he points out the fact that it would be impossible to test a multiplication function f(x,y) = x*y for any large values of x and y across the entire ranges of x and y. My question concerns his misc. remarks on "lousy hardware". I know the essay was written in the 1970s when computer hardware was less reliable, but computers still aren't perfect, so they must make calculation mistakes sometimes. Does anybody know how often this happens or if there are any statistics on this?

• Unlock all private keys on Ubuntu, entering password only once at login

  - by conradlee

  I login to Ubuntu 12.04 using a password. Later on, when I use my browser(Chrome), I'm asked for a password to unlock the keychain so that the browser can access my saved credentials for various websites (it's the same password). Also, whenever I use SSH to connect to other computers using my private key, I am prompted for the same password to unlock my private key. How can I make it so that I am asked for my password exactly once per login (given that my login password is the same as the one I use for all my private keys)? Probably someone will try to label this question as a duplicate of this question, this question, or this question. While these questions are similar, none of them explicitly say that there still needs to be a password entered on login, as I am demanding here. As a result, the accepted solutions just say "set your passwords to blank"--I don't want that, it's dangerous! So I am aware of the similar questions, but none of them has received the correct answer yet, because they are slightly different.

• Setting primary internet connection and network on notebook

  - by Francois

  I have installed Ubuntu on a notebook that I have configured to connect to the internet using an Iburst USB modem. This works 100% after a bit of configuring. I now have a desktop pc that I have installed ubuntu on, and would like to connect the two with a router. I bought a router with wifi, and would like to connect my notebook to the other computer using wifi, while still keeping the internet working with the usb modem. The problem is that as soon as the wifi connect, the internet connection dies. Is there a way to force ubuntu to get internet access through the usb modem, but use wifi to connect to the network? I am pretty new to ubuntu so any help would be appreciated. I also have a samsung galaxy tab that I would like to connect to the internet through usb modem via the wifi, so is there also a way to share that internet connection with the other computers on the network? Thanks in advance.....

• How to describe the profession [closed]

  - by Michael Kjörling

  Possible Duplicates: How to explain programming to a non-programmer? Getting non-programmers to understand the development process I was asked a question today that made me think. Here's a middle age person who apparently knows nothing about computers besides this specific application they use (I actually suggested to use Calculator, rather than hunt around the whole office for a hand-held one which had mysteriously vanished, and the fact that the computer could be used for such tasks was apparently news), asking me to explain what programming is about. In general. I tried, but am not sure I managed very well. But it got me thinking. What would be a good way to describe programming, or more generally speaking systems development, to a person like that? How have you responded being put in a similar situation?

• Oracle VDI Seminar - June-30

  - by mprove

  More from Andy Hall about Oracle VDI:  Oracle Virtual Desktop Infrastructure allows you to bring your desktop environments under control by hosting and managing them centrally in the data center. Users then connect to their desktops over the network using their existing PCs and simple client software, or with Oracle's Sun Ray Clients. Virtual desktops provide a number of benefits, including:  Cost reductions by allowing global or local changes and updates to the desktop environment from a centralized management location.  Better security by keeping sensitive data off of individual computers and retaining it safely in the data center.  Improved availability and business continuity because workers can access their desktops from nearly anywhere.  Join us to get the latest updates on Oracle Virtual Desktop Infrastructure and learn how moving to a virtualized desktop environment can help your organization, today and into the future.  Speaker:  Andy Hall - Virtual Desktop Infrastructure Product Management, Oracle Event Date: 06/30/2011 09:00 AM Pacific Daylight Time Register here_

• The Best Articles for Playing, Customizing, and Organizing Your Media

  - by Lori Kaufman

  Computers today are used for much more than generating documents, writing and receiving email, and surfing the web. We also use them to listen to music, watch movies and TV shows, and to transfer media to and from mobile devices. Below are links to many articles we have published on various media topics, such as streaming media, managing and organizing your media, converting media formats, obtaining album art, preparing media for transfer to mobile devices, and some general information about working with audio and video. You’ll also find links to articles about specific media tools, such as Audacity, XBMC, Windows Media Player, VLC, and iTunes.

• host and share files in my hosting

  - by user1314836

  I currently have a domain+hosting with unlimited hosting space for our website. On the other hand, I use Dropbox to share our organizational files and photos between about 10 users. The thing is that sharing photos uses too much space for what a free Dropbox account offers. So I am thinking of taking advantage of my hosting space, but using FTP seems not to be ideal for users who are not too skilled with computers. In addition, it doesn't handle versions in case some user makes a mess of it. And using a public FTP to upload and giving them only download permission doesn't seem a good idea as I am only the CTO. So what I want is basically to implement a local Dropbox for a few users, but I'd prefer something that is not too complex to install/mantain. Thank you a lot.

• How to control an Ubuntu PC from another Ubuntu PC over Internet?

  - by Naveen

  There are two Ubuntu PCs called A and B. A and B are connected to the Internet using two separated Internet connections. (In my case, two mobile broadband connections ppp0 x2 ) Each connection has a unique & static public IP address. What I need is to control A computer's cursor, using B computer's mouse, over the Internet. In both computers, I have allowed other users to control my computer in Desktop Sharing preferences, as below: When I try to connect to A from the B using Remmina Remote Desktop Client, it refuses to connect after trying for a while. These are my settings: I expect this to be done from an available open source software, not from TeamViewer. I found this guide harder to understand. Please provide me clear instructions... Thanks for having a look!

• Broadcom BCM4313 working, but terribly slow

  - by Ataraxio Panzetta

  Hi all, I've installed ubuntu on a Asus 1015 netbook. Everything worked out of the box except for the Wireless adapter, which i had to install with the Additional Drivers application. It apparently installed fine and connects to our wireless network, but it only works at a "funny" speed range that goes from 367Bytes to a peak of 3Kb in its best moments. I know for sure the problem is neither the network nor the hardware. Network speeds are normal under windows on this laptop and in other computers with ubuntu aswell. lspci says the card is a BCM4313 model, but the Addittional Drivers Manager says these packecege contains Broadcom 802.11 Linux STA wireless driverfor use with Broadcom's BCM4311-, BCM4312-, BCM4321-, and BCM4322 based hardware seems like it installed the wrong driver... Is there anything I can do? I'm not concerned about compiling the driver or stuff like that, but I'm not sure on where to start... any help or guidance will be very, very appreciated.

• How To Play DVDs on Windows 8

  - by Chris Hoffman

  Upgrade to Windows 8 and you may be surprised to find that you can no longer play video DVDs. Unlike previous versions of Windows, Windows 8 doesn’t include built-in support for playing DVDs. Microsoft opted not to include DVD support because so many new computers – especially tablets and ultrabooks – aren’t coming with DVD drives. Microsoft pays a licensing fee for each copy of Windows that ships with DVD support. Note: You can still use data DVDs with Windows 8. This only applies to video DVDs. 6 Start Menu Replacements for Windows 8 What Is the Purpose of the “Do Not Cover This Hole” Hole on Hard Drives?

• Tired of windows. How Can Switch to Ubuntu ?

  - by Noah

  Im thinking strongly about starting to use Ubuntu. I am tired of windows and how every computer i get/have runs with it. I'm not real good with computers, but I'm good enough for my needs. Ive used Ubuntu in the past of a friends computer and always pretty impressed with what he could make it do, look like, and the fact that was able to run windows along with it. His computer never crashed or got viruses. That sounds like something i could get used to. Id like to here what some of you think.Also I keep reading about a live cd that allows you to run Ubuntu with windows to basically try it and not have to commit. If so how can I get that. i havent been able to find it anywhere.
