• How do I get my programs to communicate with each other

  - by Benjamin Lindqvist

  I'm basically just getting started with programming. The problem I have with progressing is that I have a hard time learning stuff just for the sake of knowing them - I do better when there's a problem to be solved or a task to be completed so I can learn 'on the job'. So I'm interested in starting some interesting project. I know the basics of Python, Java, Matlab and some C++ aswell and I know enough about microcontrollers to make LED blink etc. The type of stuff I'm looking for is for example scraping some weather forecast site (with Python) and outputting the chance of rain to a LCD display, or a program that makes chrome open and log in to facebook if I say "HAL, time for facebook", or more generally, a program that reads serial/USB input, looks for certain sequences and sends instructions to some other program if it finds one. Do you open some kind of shared stream in which one program reads and one writes? What do I need to read up on to do accomplish this myself? I have no experience with linux or the linux terminal, but looking over peoples shoulders makes me suspect that's what people use. Is that correct?

• How can I to take an HDMI TV broadcast and overlay text in real time?

  - by ObligatoryMoniker

  Our company wants to be able to have LCD TVs displaying TV with the ability to add an overlay, like a stock ticker at the bottom of the screen, where human resources can add content to be displayed. I have been trying to nail down the correct terminology for this and come across terms like Keying, Compositing, Live Broadcast Graphics Presentation, and Hardware Overlay but I don't know which of these terms is truly the correct way to refer to what I am trying to do. Black Magic offers a product that seems like it can do what I am looking for but their product seems like it is geared for a totally different purpose than what I would be using it for. Compix also seems to have a product that would do what I need but again it seems like killing a fly with a sledge hammer. How can I to take an HDMI TV broadcast and overlay arbitrary content in real time?

• FTP script download from linux to windows

• Can a UPS give off an EM field capable of interfering with desktop components?

  - by Magsol

  I own an APC Back-UPS ES 750; it's about 4 years old, and is the only major component remaining in a question that has been boggling me for the last 18 months. (Yep, I originally posted this question about the possessed desktop, and while I marked a solution and closed the question, a week later the same problem returned) I've tried plugging the desktop straight into the wall (but left the other components plugged into the UPS) and the desktop still froze. Is it possible that the EM field generated by the UPS is interfering with my desktop components and causing these otherwise-unpredictable system freezes? To me this sounds like a long shot, but aside from my twin LCD monitors, that just about takes care of all the major components.

• Thunderbird: possible to change selected email highlight color (when no focus) ?

  - by Rabarberski

  Is it possible to change, in the message list of Thunderbird 3.0, the highlight color of the selected message when the list does not have the focus? The highlight color for the selected row is blue when the list has the focus, this is very clear. But when the list does not have the focus (e.g. after when you click in the message preview area), the highlight color is dark grey. However, this dark grey doesn't really stand out against the alternating row highlighting in the list (at least not on my laptop's LCD screen), making it difficult for me to quickly locate the message I've selected. So, any way to change this dark grey highlighting?

• Shortcut Keys for external monitor with XP

  - by Rhys

  Last night my laptop (samsung nc20 running XP) fell off the table and the screen cracked leaving me unable to see anything. I have arranged for a it to be repaired but want to make a back up of several folders before it gets sent away. I was planning to use my parents LG LCD tv as an external monitor so I can see what I am doing when copying things to but after plugging it in nothing seems to happen (works instantly on another laptop running vista) and hotkeys seem to be of no use at all. Does anyone know the series of shortcut keys I will need to do to get XP to use an external monitor? Thanks in advance

• Grub: Legacy 'ask' parameter no longer supported

  - by leeand00

  I'm trying to change the resolution on my base shell (the Ctrl+Alt+1) shell in Debian so that it supports my ViewSonic monitor. The shell appears really fuzzy when it is displayed on my lcd monitor, but GRUB looks fine when it's displayed. In I tried changing part of the GRUB_CMDLINE_LINUX_DEFAULT to 'vga=ask', and now I get the error on booting up 'Legacy 'ask' parameter no longer supported' Has this 'vga=ask' value been changed to something else? Note, I tried setting it to 'vga=782' after finding a list of screen modes here and the shell font got real huge for a few seconds during boot up, and then switched back to it's awful fuzzy self again, when I went to use the Debian Bash shell. UPDATE Tried suggestion in this question, it works without fuzziness until the last resolution change which displays the user login to the shell.

• Template standard controls for an entirely new look and feel

  - by T

  This is the  Ineta Live player without the O’Data Feed.  It is a good example of taking the plain Media Player provided with the Encoder install and re-templating it to make it your own.  It also has a custom scrub control that is added in.  I generally put my tempates in a separate resource file.  On this project, I discovered that I had to include the template at the document level because I needed the ability to attach some code behind to fire change state behaviors.  I could not use the blend xaml behaviors for change state inside the template because the template can’ determine the TargetObject.   Version 1.01 – 6/10/09 (wow how did a week slip by)

  - by jasonh

  I'll start with multi-monitor support. I'm trying to set up a Macbook to use an external display and I can't for the life of me get it to move the Dock over to the external display. That and it won't let me disable the Macbook's internal LCD. Please put one item into each post so that the community can vote on each issue. Also please list any workaround if you have it and what version of the OS it applies to. Thanks!

• Monitor resolution messed up somehow

  - by Kelp

  I purchased the Westinghouse 22" LCD LCM-22w3 a few years ago, and now it's been acting up on me. I just booted into Windows 7(without changing any settings), and the default resolution is 1600x1024, and it allows me to select a refresh rate of up to 85 Hz(it didn't let me do that). I usually have my resolution set to 1680x1050 with a refresh rate of 60 Hz. Now, that resolution does not even appear in the list. Does anyone have any idea of what could be the problem and how to fix it? Edit: I am not sure if this will help, but when I go to change the screen resolution, the monitor is known as "Generic Non-PnP Monitor". It used to be referred to as "Generic PnP Monitor). I tried to disable Generic Non-PnP Monitor, but when I restart, it uses that monitor again. Edit 2: I created a custom .inf file using Powerstrip, but that does not work either. The monitor settings are being stubborn.

• Why do I have no TTY on a basic Ubuntu 9.10 server install?

  - by pr1001

  I have reinstalled Ubuntu 9.10 Server several times on a bog standard 1RU server and each time I finish the install and reboot I see GRUB run and am then presented with a black screen. The machine is running just fine, as I am able to SSH in, but I can't see anything on the attached monitor. I have a simple LCD screen connected via VGA and a signal is apparently being output to it, as it doesn't go asleep. Looking at /var/log/syslog I see: Mar 24 14:57:44 bridge5 rsyslogd-2039: Could no open output file '/dev/xconsole' [try http://www.rsyslog.com/e/2039 ] However, I later see: Mar 24 14:57:44 bridge5 kernel: [ 0.001368] console [tty0] enabled Any thoughts? Thanks!

• 1080p Screen resolution problem after 10.04 to 12.04 update

  - by Ale

  I have a Samsung LCD 40" with a NVidia GeForce 6150SE nForce 430 Card. I recently upgraded from 10.04 to 12.04 and the best resolution I can get is 1360x768. I've tried the propietary drivers available on the repository kmod:nvidia_current kmod:nvidia_173_updates kmod:nvidia_current_updates kmod:nvidia_96 kmod:nvidia_96_updates kmod:nvidia_173 I've also downloaded latest from NVidia's Web, version: 295.40. But still no luck. With Nouveau driver, I can only get 1024x768. I know there is no problem with my hardware (video card, cable and monitor), I was using it perfectly on 10.04. Can anybody suggest something else I could try, to get my 1920x1080 resolution back? Thanks in advance. Here are some more information, that I got reading other similar posts on askubuntu. $ lspci | grep VGA 00:0d.0 VGA compatible controller: NVIDIA Corporation C61 [GeForce 6150SE nForce 430] (rev a2) $ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 320 x 240, current 1360 x 768, maximum 1360 x 768 default connected 1360x768 0 0 0mm x 0mm 1360x768 50.0 52.0* 1024x768 51.0 800x600 53.0 54.0 55.0 680x384 56.0 57.0 640x480 58.0 576x432 59.0 512x384 60.0 400x300 61.0 62.0 63.0 320x240 64.0

• Reboot to fail safe mode when root file system is full

  - by Richard

  I have a system running on a 4GB Nandrive. When the drive is full, Ubuntu will not boot :( and I have to plug in a rescue thumbdrive to delete files. The problem is the hardware is not easily accessible except via network. Is there a sure-fire way to boot Ubuntu, say, to RAM or other means when the disk is full or on any other errors in the normal boot process? In other words, is there a fallback rescue boot mode with networking? Thanks for any advice.

• Mini DV and DVI Conversion

  Video card is: AMD HD 6950 My video card comes with 1xHDMI, 2xDVI, and 2xMini DV ports. I have always used VGA and DVI only. I have the HDMI already connected. I want to hook up 2 more display.

The miniDV or the DVI? 2) I need to run a long cable maybe 15-25 feet, this might change the answer to question 1, is an HDMI long cable 20+ ft going to be better than a 20ft DVI or miniDV ?

• Display Resolution Getting Changed Automatically (sometimes) - Win7x64 - Asus M3A78-EM

• How to Enable Priority Inbox on Android (and Setup Important-Only Notifications)

  - by The Geek

  Yesterday Google released an updated Gmail application for Android 2.2 phones that supports the Priority Inbox feature—and more importantly, allows you to change your notifications to only alert you for important email. Let’s take a look. Note: If you’ve never used Priority Inbox, you should really give it a try—it rearranges your email into what is and isn’t important, and you can customize how it classifies messages easily. The idea is that it learns over time, so if you send a lot of emails back and forth with somebody, it will know that they are probably important—you can manually adjust the settings as well. To update the Gmail application, you’ll want to head into the Market and access Menu –> Downloads, where you should see Gmail in the list, and it should let you update from there. If you don’t see an update, you’re either not running Android 2.2, or it has already updated automatically Latest Features How-To Geek ETC The 50 Best Registry Hacks that Make Windows Better The How-To Geek Holiday Gift Guide (Geeky Stuff We Like) LCD?

• Tasks, jobs, activities, operations... which term to use when?

  - by Paul Stovell

  My application has a number of different asynchronous 'things' that it performs: There are things that fire off a schedule (every 5 minutes) There are things that are fired when a user clicks a button There are things that are triggered by an incoming web service call I use the terms like this: Scheduled things = Jobs User-triggered things = Tasks Web service-triggered things = Operations Tasks are quite complicated, so they're implemented using a hierarchy of different objects which I call Activities (operations and jobs may also begin to use these Activities as their building blocks). I feel like I might be using the wrong terms - for example, would you expect something that happens every 5 minutes automatically to be a Job or a Task? Is there an industry standard for this? All of the words seem to mean the same thing.

• 12.04 - Disable the HUD trigger key [ALT] in Emacs & Terminal

  - by EoghanM

  An answer on How to disable HUD in Unity 2D? points to https://bugs.launchpad.net/unity-2d/+bug/947613 where the ALT key will be made reconfigurable. Apart from emacs usage, I'm reasonably happy with using the ALT key to bring up the HUD. While using emacs though, the ALT key is tapped frequently to invoke commands. Should emacs be special cased with respect to the ALT key? I'm wondering what the situation is with games; surely lots of games repurpose the ALT key for their own use, e.g. to fire a weapon? If so, could the same be applied to Emacs, i.e. prevent the ALT key in emacs from triggering the HUD. Edit: just realized how extensively I use the ALT key in the terminal: a quick tap of ALT+B to move back a word loses focus of the terminal and brings up the HUD. Aghch
