• Ubuntu 12.10 WiFi Problems

  - by Sean Webber

  I have a 32 bit machine running Ubuntu 12.10 with WiFi on it. I have a WPA2 network at home, but if I leave the USB Adapter plugged in while it boots, it infinitely keeps asking for the network password but never connects. If I plug it in after boot, it will connect but then I can't access ANYTHING on the LAN or Internet because "the DNS servers are unreachable". Now, if I leave the computer on a while, I get lucky sometimes and it MAGICALLY decides to connect for a little bit, lock the machine though and the Internet's gone again. The weirdest thing, is when I am connected but can't get to the internet, I do a netstat or ifconfig wlan0, I do have an IP address and everything. It says I'm connected but its not. I have a Realtek RTL8188CU USB adapter.

• Kindle for PC via Wine

  - by Mollikins

  I've been checking out all the free books on Amazon and I really want to get the Kindle PC program running on my computer so I can download, read, and manage my e-books. I realize that Calibre can be used to manage e-books and I do have that downloaded. However, Amazon won't let me download ebooks unless my PC is registered in their little Kindle program and I'd like to just keep things streamlined by playing by the rules for once. I've viewed so many tutorials and advice for setting it up. I have Wine, I have Kindle for PC, I set it to Win98, all of that. However, when I try to open KindlePC from the Wine menu or from the desktop icon, nothing happens. No error messages, nothing. I don't know what might be wrong. Please let me know if you have any experience with this and any suggestions!

• Help with Dial Up

  - by iSeth

  I am trying to set up a computer for my friend that has dial up. The problem is nothing I try can detect the modem. GnomePPP can't find it and I can't figure Kppp out. I've been looking all over the net on my ethernet trying to find an answer but I keep getting routed back here. I have also tried using scanModem and it finds something like Conexant Systems, Inc. HCF 56k Data/Fax/Voice Modem but the rest of it is really confusing. I've also tried this but I'm not very terminal savvy and it didn't work. It seems like I have to compile a driver but I don't know which one or how to do it. I have also tried multiple modems. Any help would be appreciated. Thanks EDIT: scanModem thinks the modem is disabled on startup. EDIT: I reinstalled Ubuntu but the problem persists.

• What You Said: How Do You Set Reminders?

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your favorite tricks for staying on top of your tasks with timely reminders. Now we’re back to highlight some great reader tips (including a bit of software older than some of our readers). Most of us have to-do lists longer than we can do in a given day (or week!) and a constantly changing set of demands and next-actions. Having a timely and effective reminder system is the difference between dropping the ball and getting things done; how exactly that reminder system plays out, however, varied greatly from reader to reader. OJMDC sticks with analog reminders: Sticky notes in the middle of my monitor and in my wallet. I’ve tried my phone apps but I typically disregard them. HTG Explains: Is UPnP a Security Risk?

• SPARC T5-4 Engineering Simulation Solution

  - by Mike Mulkey-Oracle

  A recent Oracle internal performance evaluation for computer-based product design demonstrated that Oracle's SPARC T5-4 server running MSC's SimManager simulation software with Oracle Database 12c consolidates the work of multiple x86 servers while delivering better overall performance.   Engineering simulation solutions have taken the center stage in helping companies design and develop innovative products while reducing physical prototyping costs, and exploring a larger design space, resulting in more design possibilities. For this solution, a single SPARC T5-4 server running Oracle Solaris 11 was deployed to consolidate the MSC SimManager server, the Oracle Database 12c server, and the web application server onto a single platform. An automotive design workload was deployed to demonstrate how the SPARC T5-4 server can be used to consolidate the work of multiple x86 servers and deliver better overall performance while reducing complexity and achieving optimal product designs.  A joint Oracle/MSC Software solution brief describes this in more detail:  A Simplified Solution for Product Lifecycle Management —MSC SimManager on a SPARC T5-4 Server

• How to find manually installed packages?

  - by queueoverflow

  I installed a plain Ubuntu 10.10 on my computer and installed some software via apt-get. Last week I managed to break everything and just started from scratch, and I need to reinstall my software. Is there some way to create a list with all the packages that I have installed manually? So that it would give me a list like „texlive, ...“ and not „texlive, texlive-dep1, textlive-dep2, ...“ and all the standard packages removed? If I could somehow figure out which programs out of the regular install I have removed, that would be awesome too!

• What is the history of why bytes are eight bits?

  - by DarenW

  What where the historical forces at work, the tradeoffs to make, in deciding to use groups of eight bits as the fundamental unit ? There were machines, once upon a time, using other word sizes, but today for non-eight-bitness you must look to museum pieces, specialized chips for embedded applications, and DSPs. How did the byte evolve out of the chaos and creativity of the early days of computer design? I can imagine that fewer bits would be ineffective for handling enough data to make computing feasible, while too many would have lead to expensive hardware. Were other influences in play? Why did these forces balance out to eight bits? (BTW, if I could time travel, I'd go back to when the "byte" was declared to be 8 bits, and convince everyone to make it 12 bits, bribing them with some early 21st Century trinkets.)

• Elantech trackpad being identified as a logitech wheel mouse

  - by user11895

  I recently purchased a Samsung RF510 laptop computer, which I absolutely love. However, upon installing Ubuntu 10.10 onto it I couldn't get the trackpad to function properly. It worked as a basic mouse (point and click) but had no functionality for edge scrolling or any of the multitouch settings the trackpad is capable of. After doing a lot of research I discovered the reason is a known issue where the Ubuntu kernel will improperly detect an Elantech trackpad as a logitech PS/2 wheel mouse, and as such will gain none of the functionality that seems to be coded for synaptics trackpads. The question I have is: does anyone know a way to get this working properly? This is my first time trying to run Ubuntu on a laptop (actually, it's my first laptop in the last 12 years) and I'm finding the experience to be intolerable without the basic scrolling/zooming/etc I've been used to using for as long as I can remember.

• Scammers on the lose pretending to be Microsoft

  - by John Paul Cook

  Minutes ago I received a phone call that the caller ID listed as “Out of area”, which I knew was a bad sign. It was difficult to understand the caller because of his very thick accent. He told me that he was from Microsoft and that my computer was throwing a large number of errors and he was calling to help me. He directed me to use Windows R to open a run dialog box, type eventvwr and then look at the Event Viewer. Within Event Viewer, he instructed me to open Custom Views and then open Administrative...(read more)

• Graphics problems: noise-like glitch, and screen freezes in Ubuntu 13.04

  - by user207253

  I have recently upgraded to 13.04 and am using unity. I am experiencing two intermittent problems with the graphics: 1) All or part of the screen is taken up by 'noise', which lasts for about a second, see screenshot: 2) The launcher panel freezes. I can still move the mouse and the keyboard responds to function keys (I can dim the screen), but I cannot select anything. At the moment I recover by ctr-alt-f1, and restarting lightdm. My computer is a Samsung Chronos 7 laptop, model NP700Z5C, with Intel HD 4000 graphics The same problems occur with lightdm and gdm. I have attempted to install the intel drivers (as the screenshot hints) but these are not indicated as additional drivers in software & updates so I'm not sure whether they are in use. Any suggestions?

• About languages strongly typed with late binding, do they make sense?

  - by llazzaro

  I never learnt anything about VB6 (and I dont want to) but I wanted to search for bad things in computer software, so my first though was VB6. So for example, VB6 was strongly typed with late binding. Makes some sense to have a language with that combination? (I dont think so). I want to know reasons of why VB6 was like this! or why is good idea for a lenguage to be like this. Bad things that happend with a lengugage like this? good things?

• How do I get Ubuntu One on Win7 to authenticate my login?

  - by Fred jones

  I just got a new computer running Windows 7 home premium, I used to have Ubuntu One working great on my Ubuntu desktop, but now, running win7, I know my login email address and password is correct, but it still says 'Authentication failed'. Googling the problem, looks like it may be because a device was removed from my list of devices, but the only device listed is my previous Ubuntu workstation, and nothing has been removed. I also checked the windows firewall and Ubuntu One is allowed on all interfaces on incoming and outgoing, and still authentication fails. Web login to my Ubuntu One account works fine.

• How is your working time distributed between coding and thinking?

  - by mojuba

  ...in percentage. For example 60/40 or 90/10 or 100/0. My hypothesis is that the bigger the proportion of time you spend thinking the smaller your code can be as a result (and the less time will be needed to write it down). Think more, write less, in other words. Do you think it is true? As a side note, I think in typical software companies thinking is not part of the culture anyway: you are usually supposed to be sitting there at your computer typing something. You will almost definitely be noticed by your managers if you wander about with a blank look thinking over your next steps with your code. Too bad.

• Using apt-get from Canada

  - by Advant Edge

  I am using Ubuntu Server 12.04 LTS, and until yesterday, everything was quite peachy. I have installed several packages (MySQL, apache2) and to my knowledge have those configured correctly. Upon configuration of phpMyAdmin, I found that I was missing the directory path /etc/phpmyadmin, which got me thinking about the install. I am new to Ubuntu, so I guess I missed the message telling me that I did not download phpMyAdmin successfully. Anyway, trying to use apt-get yesterday/today results in "Failed to fetch..." messages, even if just to run sudo apt-get update. Some notable details: ···no GUI, command line only (sudo apt-get gksu fails, go figure) ···can ping 4.2.2.2, so I know the internet is out there (somewhere) ···this is a dedicated computer, using Samba to share files with Windows, which does work ···attempted to edit my /sources.list file, for various American/Canadian mirror, to no effect ···ensured I have correct DNS settings in /etc/networks/interfaces I'm not sure where along the way it happened, but I seem to have lost connections to repositories... :) Any advice (including GO BACK TO WINDOWS) is appreciated.

• i accidentally disabled my ubuntu profile

  I was trying to upgrade my 2nd computer's hard drive, and in the process, I un-admin'd and disabled my account. I'm using the guest account right now. I've tried everything that ask ubuntu has to offer (or at least after 5 hours of searching, trying, and failing) i.e., creating a new account (didn't allow me to do it), usermod, passwd, anything involving sudo, hell, I can't even get into recovery mode with the left shift thing... I really want to get into my account. Please help me.

• Can I set Ubuntu 12.10 to automatically reboot to Windows once only?

  - by Bill Tetzeli

  Is there some way when I'm in Ubuntu 12.10 that I can set it to reboot automatically to Windows just once, so that when I'm in Windows I can reboot and it will automatically boot back into Ubuntu? I need this because often when I travel I access my home computer for email and other personal info that I don't want to travel with or leave to the tender mercies of the "cloud". On rare occasions, I need to temporarily boot into Windows 7 to do something Windows-specific, but then I want to be able to boot back into Ubuntu because that's where most of my computing takes place. Any ideas? Thanks in advance! Bill

• Need help to install persistent Ubuntu on USB drive

  - by Junior

  I am a new user of Ubuntu. I would like to install a persistent Ubuntu 11.04 to my USB stick, and it should be able to work as a guest OS running on Windows so that I can boot it on other computers other than the one which I used for the installation. I have used several creators such as unetbootin, however from my understanding it can only create Live Linux which I am unable to save my configurations and files. If it's possible I would like to bypass the BIOS, that is to say that I can just load from the virtual machine without having to restart the computer. Thanks in advance!

• Dash doesn't launch Gedit at the first try

  - by GUI Junkie

  I'm curious to find out what's going on here. Push the [windows] key -- Dash pops up. Type 'ge' -- 'Text editor' appears. [Enter] -- Nothing happens. With any other program, it launches the program. Repeat the steps and gedit launches. From terminal, gedit doesn't start. In the system monitor, it's 'sleeping'. This happens in my session, in my wife's session on the same computer, gedit runs. Any idea why gedit sleeps at the first launch?

• Reliability Monitor is the Best Windows Troubleshooting Tool You Aren’t Using

  - by The Geek

  When it comes to hidden gems in Windows, nothing beats the Reliability monitor tool, hidden behind a link inside of another tool that you don’t use either. Why Microsoft doesn’t shine more light on this really useful troubleshooting tool, we’ll never know. Reliability Monitor tracks the history of your computer — any time an application crashes, hangs, or Windows gives you a blue screen of death. It also tracks other important events, like when software is installed, or Windows Updates loads a new patch. It’s an extremely useful tool. And yes, it’s in Windows 7 and 8… and even 8.1. It might be in Vista, but who uses that anymore?

• How To Remotely Copy Files Over SSH Without Entering Your Password

  - by YatriTrivedi

  SSH is a life-saver when you need to remotely manage a computer, but did you know you can also upload and download files, too? Using SSH keys, you can skip having to enter passwords and use this for scripts! This process works on Linux and Mac OS, provided that they’re properly configured for SSH access. If you’re using Windows, you can use Cygwin to get Linux-like functionality, and with a little tweaking, SSH will run as well.What is a Histogram, and How Can I Use it to Improve My Photos?How To Easily Access Your Home Network From Anywhere With DDNSHow To Recover After Your Email Password Is Compromised

• Ubuntu partition won't display on screen

  - by Danny

  I installed ggobi on my MacBook Pro, and it wasn't working right. I looked up some information, and found this site: Gtk Warning: Cannot open display I followed the vague instructions, but I think I just typed export DISPLAY=:0 directly into my terminal (I'm still in my Mac partition at this point). Fast forward a few days, and I try to go into my Ubuntu partition. It only gives me command line options. I remember my reckless input from a few days back, and I'm certain that it is the issue. My problem is that I have no idea how to get my previous display settings back. My Mac partition seems unaffected, but it'd be nice to get back into my Ubuntu partition. My last resort is completely reverting my computer to my most recent backup before I changed it, but if anyone out there knows how to fix this, I'd greatly appreciate it. Thanks in advance.
