• Horizontal title bar shadow while in full screen

  - by Atcold

  While in full screen the horizontal shadow of the title bar (I am not too sure about its name) appears on top of everything. How can I get rid of it? It's quite distracting while coding in Guake mode and annoying while watching movies. In the picture I've setup Guake with some transparency (that's why you can see things underneath), but the shadow is on the top of everything while I am in fullscreen. This, as I have already said, happens to me both while I am watching movies or programming in fullscreen mode. This usually happens after awaking the laptop from hibernation. Now it looks like it has gone, but I am still wandering if someone knows something about it. And here back it is :[ I'm running Ubuntu 13.04

• Upload Recordings Of The Problem To Your SR

  - by jhpierce

  Do you find yourself trying several times to explain a problem in a Service Request? Does the support engineer ask more than once for clarification? If so, you might be interested in DITO -- Demo It To Oracle. DITO uses CamStudio (free download!) to record the exact nature of the problem, and upload the output to your SR. The following articles provide more details: Working with Support - MOSSOS (Doc ID 1265130.1) "Demo It To Oracle" (DITO) - CamStudio Help ( Doc ID 11.1) Why take up valuable time first explaining the problem, then trying to get a web conference setup to show exactly what is going on? The next time you file an SR, try including a recording showing exactly which application is failing, where it is failing, and what it looks like when it fails.

• Ubuntu 14.04 + nvidia-331-updates makes a blank desktop screen

  - by Achint

  I upgraded my installation from 13.10 to 14.04. The problem is that whenever I install the Nvidia drivers from the GUI, upon reboot or trying to login again it only shows the wallpaper of my desktop and nothing else. The mouse does move around, but nothing works. I am unable to open a terminal or do anything else. If I go into the tty console and purge the drivers, then things seem to work again. I have an Optimus setup, with an onboard Intel and discrete Nvidia GTX770M card. It's a 64-bit architecture. I really need to work with CUDA, and was hopeful after hearing that nvidia-prime was released, but this is a real downer. Any help on this?

• Ubuntu not booting from USB on laptop (no optical drive)

  - by Jamie

  I'm using a Kingston 16GB USB, with the Unetbootin program. (I've tried both downloading the installation iso manually and adding it, or using the program to download.) I've tried creating the bootable USB on an iMac, the laptop and also a desktop. I've booted into the setup of the laptop and changed the boot order to make sure it boots from that drive first. (There is no optical drive so that isn't a problem.) It's an Acer Aspire AS3810TZ. Upon booting it gives this message: SYSLINUX 4.03 2010-10-22 EDD Copyright (C) 1994-2010 H. Peter Anvin et al I get this no matter how I create the USB, it just sits there. I left the laptop for an hour and it hadn't moved. I've also tried on a different 4GB USB (Generic) and that did the same.

• Recommendations for a quick and easy discussion forum installation

  - by BeachRunnerJoe

  Hello. I did a couple quick searches on this topic and both Google and this site yielded poor results, but I was wondering what's the quickest way to setup a discussion forum on my website. Preferably one that has a decent Admin dashboard. My website is very static (e.g. it has one index.html, a stylesheet, and a javascript) and it will most likely be hosted on GoDaddy.com. The last time I installed a discussion forum was six years ago and it was phpBB. I'm sure that's still an option, but I'm (hoping) wondering if there are better, free, and as-easy alternatives to phpBB. Thanks for your wisdom!

• Using 'new' in a projection?

  - by davenewza

  I wish to project a collection from one type (Something) to another type (SomethingElse). Yes, this is a very open-eneded question, but which of the two options below do you prefer? Creating a new instance using new: var result = query.Select(something => new SomethingElse(something)); Using a factory: var result = query.Select(something => SomethingElse.FromSomething(something)); When I think of a projection, I generally think of it as a conversion. Using new gives me this idea that I'm creating new objects during a conversion, which doesn't feel right. Semantically, SomethingElse.FromSomething() most definitely fits better. Although, the second option does require addition code to setup a factory, which could become unnecessarily compulsive.

• memory and time intensive php task

  - by Goddard

  Sorry if this question has been asked before, but I couldn't find anything usable. I'm working on a project for a client and currently I have to loop through the users table which is about 3000 records and still growing. I have to do some calculations on a nightly basis which I am going to be using cron/php. The calculations script uses about 3.5mb of memory and takes about 1 second to run. When loading individual users my current php setup handles this fine, but if I try and loop through the user list my php script execution time runs out. I've read after doing some searching that I can make the page reload itself after each user calculation and just keep my previous place in the loop and this sounds like a good idea, but I wanted to hear some opinions from others that have handled similar situations and how you handled these types of tasks. Thanks.

• Looking for a 24 Hour project for multiple languages [closed]

  - by Daan Timmer

  Right two friends and I came up with this idea of having a 24h programming competition. Where we are going to meet at one place and program away for 24hours long. Though we need a 'project'. Something that needs to be made within 24h. Doesn't have to be a real thing, just a nice learning 'thing'. The rules that we setup for ourselves is that the project can be programmed in any language of our own choice. What I know is that one guy is a PHP enthousiastic, we've got a C#/.NET person. And I am quite easy in languages and speak quite a few (PHP/C#.net/C++STL/Python/JavaScript/Java). Anything really language specific is out of the question. Is there anyone who happens to have a great idea for this?

• Best strategy to discover a web service in a local network?

  - by Ucodia

  I am currently doing some research for a project. The setup is simple, I have a computer running a service in my home network and any device connected to that same network should be able to discover the service automatically and use it. I have no specific technology requirement whether it is on the server or client side. The client knows about the service definition. Other than that I have no idea what strategy to use, what technology to look at or whether I should go for a SOAP or a HTTP based service. I think going HTTP with REST API is the best for targeting all devices but I am opened to any suggestions. Thanks.

• How do I set up a server for SSH?

  - by Rob S.

  At my workplace (a university) we have two Ubuntu servers. One is a teacher server and the other is a student server. I am currently setting up a new server to replace the existing teacher server. The new server is currently online and I am trying to get it setup so I can SSH into it from my home. Right now, I can SSH into the existing teacher or student server and then SSH into the new server. However, I can not SSH directly into the new server. What must I do so that I can SSH directly into the new server? Thank you very much in advance for your time.

• Problems with No-IP redirecting

  - by user171156

  I am setting up a webserver on my ubuntu desktop 13.04, everything is working fine except; When trying to access the server through the external host using no-ip, it gives the original index created by apache on setup. While when I try to connect to the server via my real IP address from externally, it goes to the correct index. I have been trying to figure out what the issue is on this problem as nothing is working because of that bad redirect, I'm wondering if anyone of you could help me out, or advise me in the right path. Thank you very much! PS; If more info needed I'll provide, but this should explain it all.

• Will adsense 'use' comments between the adsense opening and closing tags for ad targeting?

  - by SuperSpy

  I've got a simple website on which students of my school can see their timetable. I setup adsense three weeks ago and everything is working fine. But I would like to help adsense. Since only a timetable and a few instructions are shown, there is scarcely content to which ads can relate. Idea: <!- google_ad_section_start –> <!-- Students like clothing ... and bargains, etc.--> <!– google_ad_section_end –> Will this work? Or are there other ways to help adsense?

• Cannot mount USB disks due to "not authorized" error

  - by shadovv

  I have Ubuntu 12.04 (.2?) installed. I don't plan to need GUI after setup so I modified the grub to start in console. However, whenever I want to start up GUI I need to type startx. Simple/basic stuff. However I seem to be hitting a snag: I am having trouble mounting/accessing USB flash drives in the GUI I started in the console. "Unable to mount location - not authorized". Seemed like it should be an easy fix, but can't figure out how I'm overlooking it. Can someone help me out?

• Windows 7/ 12.04 Dual Boot Mess

  - by Ben

  I am certainly new to ubuntu (linux in general)... I added ubuntu 12.04 as a dual boot to a brand new desktop which had win 7 pre-installed. Both work well Then I tried to change the order of the boot menu to make Ubuntu first and Win7 second... I did this from the windows side (it seems that my setup is relying on windows bootloader, which I don't think I need to change) using the built-in startup manager (I think that's what windows calls it- it's in the control panel). I set Ubuntu as first (default if no user input). then... I ACCIDENTALLY ("hmmm...I wonder what this button does?") set the menu timeout to "0" Now, I cannot change the menu timeout (because I cannot get into windows) and without doing so, I cannot select windows as the OS I would like to boot(I cannot get into windows). Any Ideas?

• I try install dhcp3-server, but /etc/init.d/dhcp3-server file is missing. Whats going on?

  - by hydroparadise

  I've found several how-to's that essentially go through the same process in setting up DHCP. Here's a link that has the list of step needed install and setup DHCP. I follow all the steps and find that the sudo /etc/init.d/dhcp3-server restart portion returns command not found only to reveal the the file doesn't even exist. I've installed (sudo apt-get install dhcp3-server) and uninstalled (sudo apt-get remove dhcp3-server) two or three times. I'm pretty sure my config files are good because I've had to check them three times. But I don't think I'm to that point of being able to see them action it. I cant control the process. Why is the file missing? How is it supposed to get there? Help?

• Network printer gets disabled occasionally

  - by Yossi Farjoun

  I'm running Ubuntu 10.04 and have a HP-Laserjet-3005P network printer. Occasionally (perhaps related to rebooting) the printer, which is setup as the default printer, becomes disabled. After realizing that I'm not getting anything printed, I must then open printing preferences and click on "enabled". Then it prints happily until the next time that it becomes disabled... Any ideas why this is happening and/or how I could fix it? I know I'm giving very little information, I can't think of anything else to give...if there's something I should be providing, please let me know.

• Setting umask globally

  - by DevSolar

  I am using a private user group setup, i.e. a user foo's home directory is owned by foo:foo, not foo:users. For this to work, I need to set the umask to 002 globally. After a quick grep -RIi umask /etc/*, it seemed for a moment that modifying the UMASK entry in /etc/login.defs should do the trick. It does, too -- but only for console logins. If I log in to my desktop, and open a terminal there, I still get to see the default umask 022. Same goes for files created from apps started through the menu. Apparently, the display manager (or whatever X11 component responsible) does source some different setting than a console login does, and damned if I could tell which one it is. (I tried changing the setting in /etc/init.d/rc, and no, it did not help.) How / where do I set umask globally, so that the X11 desktop environment gets the memo as well?

• How do global cancel/exit commands work in bash?

  - by SecurityGate

  As I have done multiple times before, I've written bash scripts, and just general commands that go nowhere. They just blink the little command line cursor at me for infinity until I control+C the command. When I do cancel the command, what exactly is going on when I do this? Am I somehow stopping and killing the current PID I'm working on? Does it jump to a different run-level and execute something to terminate the command? On a slightly different note, I've never been able to figure out how to set up something like this in a script or program I've worked on. Since I mostly program in Ruby, can I setup something like a certain key press stops the program? Every time I've looked into doing something similar, I always end up getting hung up when it comes to user input, whether that is a loop waiting for a condition, or something like this: def Break() user_break = gets.strip end def Main() Function1() Break() Function2() Break() [...] end It seems and is incredibly bulky, and definitely isn't easily scaled up or down.
