• Left and right keys acting crazy on Ubuntu 10.10 Netbook Remix?

  - by Stephanie

  Hi guys, I just installed Ubuntu 10.10 Netbook Remix on my HP Mini 1000. Everything worked fine right up until I tried typing - apparently the left and right arrow keys on my keyboard are uncontrollable. Everything I type ends up looking messed up because the left and right keys keep automatically inserting themselves into everything I type. This also happens when I click on, say, "File" on Firefox. It starts rotating between all the different menu options even though I'm not pressing anything on the keyboard. Does anyone have any idea what's going on? Is this a problem with the keyboard itself?

• Using an iPad or Nexus 7 as an Ubuntu Second Monitor

  - by never4getthis

  Is there any way to use an iPad mini or a Nexus 7 as a second monitor through a cable? I dont want something like vnc, I need it to work through the usb cable (or any other cable). I imagine that the iPad will get a lot of hate around here, the reason why I am considering it is because of the larger screen (compared to the nexus 7). I think its self explanatory that I need this to work with ubuntu (as I am posting in this formum). Thanks for reading this highly unorganized, typo-flled (<--see what I did there?), un-cohesive post. Any help will be appreciated!

• Quand Chrome gagne 40 millions d'utilisateurs, Firefox en gagne 100 millions d'après un cadre de Moz

  Mise à jour du 21/05/10 Quand Chrome gagne 40 millions d'utilisateurs, Firefox en gagne 100 D'après un cadre de Mozilla : qui parle de déclin ? Comme d'habitude avec la Fondation Mozilla, il ne s'agit pas d'une réponse officielle. Mais cela y ressemble furieusement. Sur son blog personnel, Asa Dotzler, directeur du développement de Firefox, vient de comparer les progressions respectives de Chrome et de Firefox sur l'année 2009. Cette mini-étude fait suite aux déclarations de Black Ross, un des créateurs du navigateur, pour qui le Panda Roux est proche du déclin et la Fondation empêtrée dans une culture bureaucratique qu...

• Can't connect to wireless network in Lubuntu

  - by mike

  I have a CISCO 802.11b WIFI Mini PCI LAN card in my IBM ThinkPad T30 laptop. Is this wireless card compatible with Lubuntu? I ran it off a Live CD and it showed the network I want to connect to – but it just won't connect. I tried installing Lubuntu and during installation it also tried to connect to the same network and still nothing. I know that the wireless network is working correctly because I can connect to it with all my other devices and it works on this very same laptop when I am running Windows.

• Cross-Platform Automated Mobile Application UI Testing

  - by thetaspark

  My dissertation is about developing a tool for testing mobile applications from the GUI. Primary device is Android, but it should support Blackberry or iOs etc. I found some frameworks using Google, e.g MonkeyTalk. I am not so sure, but what I want to develop might be a mini MonkeyTalk, with minimal functionality, focused on the GUI of the application(s) to be tested. My questions: What framework(s)? I am good with Java. Can I use the xUnit family for this, and how? What should I be reading/studying? Any suggestions, links for tutorials, documentations, howtos, etc., would be very helpful. Thanks in advance.

• pulseaudio: no microphone configuration

  - by mitsch

  Updated Ubuntu to precise from oneiric on a Dell Inspirion Mini 10 (with an Intel HDA-Soundcard). I can't remember having any issues with the microphone. I didn't need it - I tried ekiga the first time in precise. I couldn't hear any sound in the echo test of ekiga, so I switched to the "System Preferences" and looked for the microphone to boost it. Surprisingly, the microphone input was greyed out - I couldn't mute or unmute, i couldn't even move the volume-slider. On the other hand: I could change the microphone-setting on console with alsamixer, so don't worry about that… :) I just wanted to ask, how to get pulseaudio back to the known, comfortable behaviour. Some newbies won't know the trick to use alsamixer… My soundcard (output of lspci): 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Greets!

• Wireless doesn't connect in Ubuntu 10.04 Lxde

  - by David

  Problem I have a Dell mini 9, and the wireless has worked without trouble in Ubuntu and Xubuntu versions 8.04 and 10.04. However, after installing lxde, the wireless doesnt connect. Network manager recognizes the local networks, and will say that it is connected, but ifconfig does not confirm the connection or the existance of a wlan0. I have another Ubuntu 10.04 notebook that works fine. My wireless device is Broadcom BCM4312 802.11b/g What I have tried I have tried to remove and install network-mananager and inxi but neither work, and sudo modprobe wl returns WARNING: All config files need .conf: /etc/modprobe.d/blacklist, it will be ignored in a future release.

• How do I reduce package content on a custom install CD?

  - by Pete Ashdown

  I normally do all my installs via PXE server, but I'm building a custom CD for kvm installs that are not on the same vlan as my PXE server. I would prefer this CD was as small as possible and it fetched packages from the network like netinstall mini.iso CD does, but netinstall doesn't mount /cdrom like the server install CD does. I need the cdrom for preseed. I've got my custom server install CD working, but it is still ~700MB. Trying to modify "dists/lucid/main/binary-amd64/Packages.gz" gives me no love as it complains that I've got a corrupt Packages.gz no matter what I do. I'd rather the preseeded mirror was used rather than CD once it gets the cdrom setup. Any ideas?

• DIY Wirelessly Charged LED Lanterns

  - by Jason Fitzpatrick

  Earlier this year we shared a clever project that turned LEDs, batteries, and PVC into mini, waterproof, and virtually indestructible lanterns. This remake of the project makes the units rechargeable. Our favorite part about this project–the upgrade to an older project and the introduction of wireless charging aside–is the fact that the maker behind it is 15 years old. It’s great to see younger people taking an interest in tinkering!

• proper model for a multi site rails app

  - by JeffTaggarty

  Hi Guys, I am not sure if this is correct place to ask this question. My apologies if it is not. I need to create a web app where people will sign up, call it main-app.com, when they sign up my code will generate a usersite.my-app.com, they will login and only be able to manage their mini site. My question is, is it correct to model this out by creating a table for site, a table for user, users belong to site and site has many users. Then I should create a content table that belongs to user AND site? is that right? Thanks Jeff

• Develop a small size software using C only for copying same data to multiple external drives simultaneously [on hold]

  - by VSP

  I want to develop a software that can copy the same data to multiple external drives, simultaneously. For example, consider a file Movie and I have 3 external drives to copy it to, and I want to copy Movie to all these 3 drives(these drives can be flash storage or external hard-disk or pen-drive etc. but have one thing in common, i.e. they are all external drives) at the same time, means when I right-click on Movie there has to be 1 option saying Copy to All Drives. It's a sort of mini-project and I want to use C language only. For starting I would like it to work only on Windows OS. What are the requirements of developing this software (not the system requirements but what will I need to develop such a software, like editor,compiler etc.)? I know this type of software must have already been developed but I want to use C language and C Language only. So, is it possible to develop such a software?

• Can't install Ubuntu 13.04

  - by Beaker1210

  I am trying to install Ubuntu 13.04 on a Dell Mini 10 that is currently running Qimo. I want to replace the old operating system entirely. When I turn on the computer and boot from the USB stick it brings up a black screen that says: Boot: I have no idea where to go from here. I created the bootable USB stick using Universal USB installer. I've used the same process for installing Ubuntu on other machines in the past have never had this issue. Thanks in advance for the help. :)

• Dell L501X Display Port Screen issue

  - by jdflorezPA

  I got a Dell XPS L501X with a mini display port to VGA connector for my External Screen. On Displays it shows me: Acer Technologies 24" (which is the monitor) but only lets me up to 1024x768 resolution (The native resolution of this monitor is 1920x1200). I tried adding a new mode with xrandr, but when I applied it, it reverted back to 1024x768. As far as I know, the display port is controlled by the Intel card, right? Any ideas or suggestions would be appreciated. Thanks Using Ubuntu 11.10 32bit

• Ubuntu 12.04 on MBPro, Early 2011, options

  - by sthysel

  I have a 2.2 GHz i7, 4GB MacBook Pro 8.3, AMD Radeon HD 6750M 1024 MB, Early 2011. As far as I see I have two options, running Ubuntu on this hardware: VMWare/Virtualbox and Ubuntu in a VM, I already ordered a 16G RAM upgrade for this. Wipe OSX and go Ubuntu native, with 16G RAM, yay ! I'm kinda leaning towards option 2 as I tend to spend 90% of my time in dev VM's at work anyway. All my other machines at home, and most at work are Ubuntu/Linux as well. I have a Mac mini on standby for the odd Itunes backup/sync. If I don't have to keep OSX around, I would like to get rid of it altogether. Ubuntu support on Mac hardware seems to be a hit and miss affair as far as I can tell. Does anyone have good success running a recent version of Ubuntu on this hardware ? Thanks

• Erratic display behaviour on 12.04 using an Asus Zenbook

  - by Azarias R

  When I first plugged in my 23 inch monitor through the mini-VGA port, everything worked...both display were detected, and worked. On the second or third plug in, the internal display would turn off, and only the external display would work. When I try to 'detect monitor', I got "could not set the configuration for crtc 63" a few times. Now, when I plug in the external display, I get a screen full of orange color on the external display, and the laptop display turns off. The only way to get things back is to force turn off the laptop and restart. Unplugging/replugging monitor doesn't work, and seems like ubuntu crashes. Can anyone help?

• OpenGL - drawing 2D polygons shapes with texture

  - by plonkplonk

  I am trying to make a few effects in a C+GL game. So far I draw all my sprites as a quad, and it works. However, I am trying to make a large ring appear at times, with a texture following that ring, as it takes less memory than a quad with the ring texture inside. The type of ring I want to make is not a round-shaped GL mesh ring (the "tube" type) but a "paper" 2D ring. That way I can modify the "width" of the ring, getting more of the effect than a simple quad+ring texture. So far all my attempts have been...kind of ridiculous, as I don't understand GL's coordinates too well (and I can't really understand the available documentation...I am just a designer with no coder help or background. A n00b, basically). glBegin(GL_POLYGON); for(i = 0;i < 360; i += 10){ glTexCoord2f(0, 0); glVertex2f(Cos(i)*(H-10),Sin(i)H); glTexCoord2f(0, HP); glVertex2f(Sin(i)(H-10),Cos(i)*(H-10)); glTexCoord2f(WP, HP); glVertex2f(Cos(i)H,Sin(i)(H-10)); glTexCoord2f(WP, 0); glVertex2f(Sin(i)*H,Cos(i)*H); } glEnd(); This is my last attempt, and it seems to generate a "sunburst" from the right edge of the circle instead of a ring. It's an amusing effect but definitely not what I want. Other results included the circle looking exactly the same as the quad textured (aka drawing a sprite literally) or something that looked like a pop-art filter, by working on this train of thought. Seems like my logic here is entirely flawed, so, what would be the easiest way to obtain such a ring? No need to reply in code, just some guidance for a non-math-skilled user...

• What's the best way to annotate this ggplot2 plot? [R]

  - by Matt Parker

  Here's a plot: library(ggplot2) ggplot(mtcars, aes(x = factor(cyl), y = hp, group = factor(am), color = factor(am))) + stat_smooth(fun.data = "mean_cl_boot", geom = "pointrange") + stat_smooth(fun.data = "mean_cl_boot", geom = "line") + geom_hline(yintercept = 130, color = "red") + annotate("text", label = "130 hp", x = .22, y = 135, size = 4) I've been experimenting with labeling the geom_hline in a few different ways, each of which does something I want but has a problem that the other methods don't have. annotate(), used above, is nice - the text is resizeable, black, and easy to position. But it can only be placed within the plot itself, not outside the plot like the axis labels. It also makes an "a" appear in the legend, which I can't dismiss with legend = FALSE. legend = FALSE works with geom_text, but I can't get geom_text to just be black - it seems to be getting tangled up in the line colorings. grid.text lets me put the text anywhere I want, but I can't seem to resize it. I can definitely accept the text being inside of the plot area, but I'd like to keep the legend clean. I feel like I'm missing something simple, but I'm just fried. Thanks in advance for your consideration.

  A little help how can I create an input query using this array?

• Why can't my vector access the variables in my nested structs?

  #include<iostream> #include<vector> #include<string> #include<list> using namespace std; struct record{ int id; string fName; }; struct cells{ list<record> rec; }; vector<cells> hp; int main() { **hp.front().rec.front().fName = "jon"; return 0; } I have 2 structs. The first struct, struct record, is composed of 2 regular variables. In struct 2, I have a linked list of type "record", which includes all the variable listed in struct 1. Why is it that when ever I attempt to access a variable in the structs, using my vector, I get the error "linked list iterator not dereferencable?"
