• How to obtain a S/MIME certificate for e-mail encryption?

  - by mghg

  There are parties, e.g. enterprises, that uses S/MIME certificates for e-mail encryption. To my understanding Thunderbird has support by default for S/MIME. But I have not found a way to obtain a personal S/MIME certificate to be used on a Ubuntu system. Thus my question: How to obtain a S/MIME certificate for e-mail encryption? Moreover, is it correct to believe that Thunderbird has support by default for S/MIME? I am fully aware of PGP, GnuPG and OpenPGP for public-key cryptography and secure e-mail communication. In my opinion, it is very useful that OpenPGP is installed by default on Ubuntu systems. But I need to find a method to communicate securely with parties that use S/MIME and not PGP/GnuPG/OpenPGP.

• Ubuntu 12.04 GTK Problem

  - by Dana Holt

  I am running Ubuntu 12.04 and compiled and installed GTK 3.4 to go through some GTK developer tutorials. Installing this version of GTK has caused problems with Unity. All system dialogs and top bar now have a different (older) look, and when I try to launch Nautilus I get the following message: Gtk-Message: Failed to load module "canberra-gtk-module" Initializing nautilus-open-terminal extension Initializing nautilus-dropbox 1.4.0 Initializing nautilus-gdu extension nautilus: symbol lookup error: nautilus: undefined symbol: ubuntu_menu_proxy_get I have run make uninstall on the newer version of GTK and reinstalled just about every package I can think of, but I am still having the same problem. How can I repair the default Ubuntu GTK libraries? EDIT Also, I noticed that my desktop icons are gone (launcher works), and I can't interact with the desktop. I can't drag any shortcuts to it, etc.

• Prevent nautilus showing partition mounted in bash script

  - by bcbc

  In my bash script I mount partitions, check them, copy files to them, and unmount. When the script mounts the partition, Nautilus pops up with a Window showing the partition and stealing focus. This is something I want to avoid. Note: I know I can change the behaviour of this in System settings, Details, Removable media, Never prompt or start programs on media insertion, but I don't want to change the behaviour e.g. if a USB stick is plugged in, I just want to prevent it in my bash script. Actually this auto display doesn't seem consistent. If I do the exact same command from the terminal, Nautilus doesn't show, and I know there are other mounts in my script that don't show. So what could be causing this? Here's an example of the code: mkdir -p $target/home mount $target/home $homedev Thanks in advance

• Auto-tiling with Yoshi's Island style tiles

  - by Boreal

  I'm creating a 2D platformer and I'd like to implement an auto-tiling system. Normally, this wouldn't be particularly difficult. However, I'd like to have tiles like in Yoshi's Island, where the graphics extend past the actual collidable tile's boundaries. Consider this image: Although the eggs and the Piranha Plant are clearly resting on the ground, the flower tiles continue behind them, out of the collidable tile. I know that it would be simple to do by hand, but extremely time consuming. Using an auto-tiling algorithm would save me a lot of time and boredom, but I'm not sure where to start.

• How To Access the Developer Options Menu and Enable USB Debugging on Android 4.2

  - by Chris Hoffman

  In Android 4.2, the Developer Options menu and USB Debugging option have been hidden. If you need to enable USB Debugging, you can access the Developer Options menu with a quick trick. The developer options aren’t just used by developers. USB Debugging is required by adb, which is used for rooting an Android device, backing it up, installing a custom ROM, taking screenshots from a computer, or doing many other things.

• Monitor resolution messed up, monitor is unknown.

  - by Kaustubh P

  Is there anyway to reset my monitor? My moitor is using the xorg.conf file. I use 10.04, without any Graphics Card. My monitor is an Acer X193W, with a native resolution of 1440x900. This is my xorg.conf file: Section "Screen" Identifier "Configured Screen Device" Device "Configured Video Device" Monitor "Test" DefaultDepth 16 SubSection "Display" Depth 16 Modes "1440x900_60.00" EndSubSection EndSection #Section "Device" # Identifier "Configured Video Device" # HorizSync # VertRefresh #EndSection I still cant view the native resolution, even when defined in the xorg file. An way I can revert to the default, or delete some files, to make the system detect the monitor again? My last resort is the cvt method, and adding it to the xrandr file. EDIT: I use Intel Drivers. My /proc/fb contains 0 VGA16 VGA

• "Email This" button with sideways counter

  - by aendrew

  I've been asked to build a design that has a "share this" area like below: I've built every aspect except the Email part of it -- any idea how best to do that? I've found http://getmailcounter.com/, but that displays a counter above. I'd personally just do a link, but it seems they're wanting some sort of analytics built in... Failing that, does anyone know of some sort of sharing system that looks like that and has all of those options? I'd just use AddThis, but its designs don't look very close to that... Thanks!

• 12.04 Random sounds sometimes after startup

  - by Timothy Duane

  I'm not quite sure what the sound is, but it has only started happening in the last two days. The only way I can describe it would be that it sounds like a wooden xylophone being tapped lightly. It will play at random intervals ranging between 1 second to a couple minutes for up to a half hour (from what I have noticed) after startup. If anybody has any ideas as to what is causing this or how to fix it I would appreciate it.

  - by Santosh

  Ubuntu 11.10 came with Firefox 7.x.x so I downloaded the Firefox 12 from its site. I did following to install this Extracted the archive. Put that extracted folder into /usr/lib/, the location was something like /usr/lib/firefox-12.0/.

During this process I didn't touched/removed from launcher bar. There was no problem in to launch firefox from the old icon from the launcher, I checked the version in about and it was 12. But as soon as I restarted the system I got the following results. Now how can I restore the icons?

• Oracle Exalogic Elastic Cloud - Planned Webcasts

  - by chuck.speaks

  I’m putting together a collection of recorded webcasts around Oracle Exalogic Elastic Cloud (Exalogic).  The plan is to do a systems overview and then multiple deep dives into hardware and software components that make up the engineered system. Those of you that are members of our partner community (Oracle Partner Network), drop me a note if you are interested in a full blown in-class delivery via PTS resources.  There is no schedule for these workshops but if there is enough interest, I would venture to guess it would roll out soon. Those of you with applications certified on Oracle WebLogic server that would like to scale to Exalogic, see me or watch this space.   Chuck Speaks chuck <dot> speaks at oracle <dot> com

• Can anyone tell me why Gnome 3 looks like as if it were a gnome fallback session in my virtualbox?

  - by Elysium

  For some reason Gnome 3 wont work in my virtualbox. Both gnome classic and gnome look exactly identical. The version of my virtualbox is: 4.1.2_ Ubuntu r38459 The 3D acceleration is on in the virtualbox and the Guest Additions is installed in the virtualbox from the software center. Obviously, the graphic card driver is installed on the main Ubuntu system I am using with my laptop. (although the post-release updates can't be installed for whatever reason) Gnome shell is installed from the software center in the virtualbox. Now the issue is that the gnome and gnome classic look like just the same. Here is an image of what gnome looks like (so does gnome classic too....so I am only posting one image): What causes this issue? By the way....I am using Ubuntu 11.10 with gnome fallback session.

• Nvidia problems. I think.

  - by Nate D.

  Let me start off by saying, I've been trying to run Ubuntu on my custom PC for about 2 years. From 10.04 to 12.04, this problem persists. When I try to boot Ubuntu from either a USB stick or a CD, I see the normal Ubuntu splash screen. It looks like it's working, orange dots are moving, but then the screen glitches and freezes. I'm assuming this happens because there are no drivers for my graphics card (Nvidia GeForce 8800, I think). My motherboard has no onboard graphics, nor does it have a VGA out. So, how can I get this working on my system? Can I somehow put the drivers along side the .img on the USB stick? I can boot from my Ubuntu USB stick on my MacBook. In case that helps anyone...

• DSL modem problem in 11.10

  - by Misterious

  Earlier I used Windows 7 and the modem used to work absolutely fine. Even when it got disconnected it used to reconnect automatically without any trouble. But then I installed Ubuntu 11.10 on dual-boot and set up the modem connection properly but the modem now disconnects much more frequently (earlier it disconnected once in 5 hours or so and after Ubuntu in 5 minutes!). Also once disconnected, it does not reconnect even when I have checked the "Connect Automatically" button. I have to restart the system to reconnect it. I the clean installed Windows and modem works perfectly fine again. What is the reason for this and how can I solve this? I really want to use Ubuntu but due to this problem I can't.

• What are the options for setting up a UNIX environment to learn C using Kernighan and Richie's The C Programming Language?

  - by ssbrewster

  I'm a novice programmer and have been experimenting with Javascript, jQuery and PHP but felt I wasn't getting a real depth of understanding of what I was doing. So, after reading Joel Spolsky's response to a question on this site (which I can't find now!), I took it back to basics and read Charles Petzold's 'Code' and am about to move onto Kernighan and Richie's The C Programming Language. I want to learn this in a UNIX environment but only have access to a Windows system. I have Ubuntu 12.04 running on a virtualised machine via VMWare Player, and done some coding in the terminal. Is using a Linux distro the only option for programming in a UNIX environment on Windows? And what are the next steps to start programming in C in UNIX and where do I get a compiler from?

• Will unity stop being a plugin for Compiz?

  - by Murphy1138

  I ask this as with the Unity Desktop running , when I try any games with my Ubuntu 12.04.1 I get so much frame rate drop with Unity and Compiz. If I switch to Gnome-Classic which uses mutter, I get a vast boost in performance. My system is an 8 core AMD with a Nvidia 460 SE that can play anything I chuck at it in Windows and I'm using the latest Nvidia drivers, but even simple games like the humble bundle gets serious lag with Unity and the only cause of this can be compiz (what I can guess). When Steam come to Ubuntu, how will this performance loss be addressed?

• Best Web Site Copying Software

  - by GregH

  I just wanted to get some opinions on the best "web site copying" software out there (free or commercial is fine). I have a site that I've recently become responsible for managing, and the previous consultant has not provided operating system access. As such, the plan is to re-host the web site. I realize there are a lot of different issues to consider in doing this. However, I don't have much choice in the matter now. The plan is to use web site copying software (ala HTTrack) to "rip" the web site, and then modify what is downloaded back in to a maintainable site. This, of course, involves HTML, css, javascript, etc on the front-end. I'd like to recover as much of the site as possible to make re-creating it as easy as possible.

• Detail of acceptance criteria in user story

  - by Kai Kramhoeft

  I have the following example for a user story with acceptance criteria. I would like to know if I am allowed to describe how the GUI must be changed to support the new feature. How much detail can acceptance criteria have? This is my example: User Story: As forum administrator I will connect persons in groups, so that people can get organized. Acceptance Criteria: The creation of a person group happens below a person group pool (person group pool is an object also visually available in the current software system) The creation happens with a context menu of the persongroup pool. Below the pool one can create new groups. A person group contains: person group-ID, description, remark May that be relevant an right acceptance criteria? Because I describe how you can create a new group by opening a context menu.

• {solved}stream TV audio through mic input?

  - by Drew S

  I have a gaming headset and use it with a few devices and am looking for a way to stream my audio through my pc from tv through the mic jack and then through the optical out. the system is detecting sound from the mic port. I would put this directly through the headset but that port is being used by my ps3. So I would like a way as I said to stream it through my pc to my headset, and it be great to have an integrated volume option in the sound drop down too. [TV - mic - Ubuntu - headset(optical out)] Ubuntu 13.04 EDIT I found part of a solution. Solution by installing pavucontrol and using "pactl load-module module-loopback latency_msec=1" I can stream the audio through my pc.

• How To Delete, Move, or Rename Locked Files in Windows

  - by Chris Hoffman

  Windows won’t allow you to modify files that open programs have locked. if you try to delete a file and see a message that it’s open in a program, you’ll have to unlock the file (or close the program). In some cases, it may not be clear which program has locked a file – or a background process may have locked a file and not terminated correctly. You must unlock the stubborn file or folder to modify it. Note: Unlocking certain files and deleting them may cause problems with open programs. Don’t unlock and delete files that should remain locked, including Windows system files.
