This week we are controlling the processes that we learned about last week. Last week we discussed processes- what they are and how to view them. Now, let's control those. Let's open the program called gedit- a text editing program. You'll notice your shell prompt will not return until the program is closed. Press CTRL-C to interrupt the program (or terminate). This works for most command-line programs but not all. Now run gedit again with an & at the end. This says we started job number 1, with a PID of 3853. Running ps shows the proccess as well. If you type jobs, this will also show you that gedit is running. (one job, number 1, command gedit &). To return the process to the foreground from the terminal, type jobs to find the number, then fg %1. To terminate again, press CTRL-C. Type CTRL-Z to completely stop a process. So if gedit is running, then type CTRL-Z to stop or pause it. You can restore the program with fg, or move it to the background with bg (bg %1). The number is optional if you only have one job running. Opening a graphical program may be essential if opening it in the GUI doesn't work or it's not listed in the window manager's menus. Do you want to completely kill the process? To do so, first type gedit &, get the PID, then type kill 3651. This will terminate the process. kill sends a signal to the process to terminate. When the terminal sees these keystrokes, it can send a signal to the process to do something. kill can have specified signals attached to it such as HUP for hang up (old school for computers that were online with phone lines), INT for interrupt (same as CTRL-C), TERM for terminate, STOP for stopping the process without terminating, CONT to continue after stopping, just to name a few. You can type kill -1 1234 to hang up, or type kill -INT 1234 to interrupt it. Use kill -l for a complete listing of signals you can send. Last but not least, you can send a signal to multiple processes. Type gedit & a couple of times for several instances of the program, then type killall gedit to kill all of the gedit instances. You must have user priveledges to send signals to processes that don't belong to you. To give you an idea of some other common processes, take a look at these commands: pstree (parent-child relationships of processes), vmstat (system resource usage), xload (system load graph) and tload (terminal graph). How do you control processes? There are other options out there. Make sure to email me [email protected] with your thoughts. And be sure to check out our sister show, http://www.hak5.org for more great stuff just like this. I'll be there, reminding you to trust your technolust.

Presenter(s): Michael Kerrisk URL: http://lca2013.linux.org.au/schedule/30020/view_talk Pipes, FIFOs, signals, datagram and stream sockets (and sockets in the Unix versus Internet domains), file locks (various kinds!), environment variables, memory mappings, event file descriptors (eventfd), pseudo-terminals, message queues, semaphores, shared memory, and good old regular files... The range of interprocess communication and synchronization (often referred to collectively as IPC) facilities available on Linux can at first seem bewildering. Which facilities should an application use? This tutorial provides an overview of each of the IPC facilities, showing the features that the different facilities have in common, and the features that distinguish them. The aims of this tutorial are to provide developers with examples of the use of each of the IPC facilities and the beginnings of a roadmap to help decide which IPC facilities are likely to be most suitable when writing new applications. I'll compare different IPC facilities using measures such as portability, flexibility, ease of use, operational limits, configurability, persistence (lifetime), access control, integration with the traditional Unix "everything is a file" model and the UNIX/Linux API in general, and specific functional advantages and disadvantages. I'll also briefly consider whether one can make any general statements about relative performance of different IPC facilities. Although aimed primarily at developers, other participants (e.g., system administrators) may find the tutorial useful for gaining greater insight into the operation, configuration, and management of the various IPC facilities. A reading knowledge of C will be useful. http://lca2013.linux.org.au/ - http://www.linux.org.au CC BY-SA - http://creativecommons.org/licenses/by-sa/4.0/legalcode.txt

Embedded Linux Size Reduction Techniques - Michael Opdenacker, Free Electrons Are you interested in running Linux in a system with very small RAM and storage resources? Or are you just trying to make the Linux kernel and its filesystem as small as possible, typically to boot faster? This talk will detail approaches for reducing the size of the kernel, of individual applications and of the whole filesystem. Benchmarks will you show how much you can expect to save with each approach. Michael will also try to collect valuable experience from participants to the talk, as well as ideas for further improvements, to add to the materials he will publish after the conference. Disclaimer: the only thing Michael won't try to reduce is the size of his presentation, as there are many resources worth exploring. About Michael Opdenacker Michael Opdenacker is the founder of Free Electrons, a company best known | for its freely available training materials on the Linux kernel and | in embedded Linux in general. Michael has a long time interest in boot | time reduction, and therefore in one of its prerequisites, which is size | reduction.

IRQs: the Hard, the Soft, the Threaded and the Preemptible - Alison Chaiken, Peloton Technology Interrupt handlers manage responses to asynchronous hardware events, keep time and queue deferred work. Hard IRQs are straightforward functions that read status and schedule a slower "bottom half". The difficulty lies with management of the deferred work. Soft IRQS and tasklets are two different mechanisms. Tasklets handle most deferred work, but network, timer and block tasks are managed directly by softirqs. Confusion comes from the realization that the softirq interface via ksoftirqd also manages tasklets. In the RT kernel, hard IRQs themselves run as preemptible threads. What precisely are softirqs and why does the kernel have them? How does handling of deferred work differ with the PREEMPT_RT_FULL kernel? These and related mysteries will be illustrated via results from tools like bpf, event tracers and mpstat that show how to detect IRQ scheduling problems in x86, arm and arm64. About Alison Chaiken Alison has been an automotive systems programmer and kernel engineer since 2011 and has worked at Nokia, Mentor Graphics, and Peloton Technology. In 2014-2015, she collaborated on-site with a customer in Germany. Alison has spoken at events including ELC and ELCE, USENIX, Automotive Linux Summit, Southern California Linux Expo and Maker Faire. She organizes the monthly meetings of the 1800+-member, 15-year-old Silicon Valley Automotive Open Source Group.

Hi everyone. I ran into an issue where my Display port wasn't working after the computer went to sleep. After searching online and trying different fixes for 2+ hours, I finally came across a very simple way to fix this issue. Please consider Subscribing if this video helped you out! Subs help my channel be able to monetize which allow me to produce additional content :) Steps to fix the Display Port: 1. Turn off the computer and either unplug it from the power source or turn off via the Power Supply's power switch. 2. Turn off your monitor and then unplug it from the power source. 3. Wait 30 seconds. 4. Plug the monitor back on, turn it on if it doesn't do so automatically. 5. Plug the PC back on or flip the PSU switch back to on. 6. Turn the PC back on and if this fix is applicable, your Display Port will now work again. NOTE: Make sure no other video cables are plugged in to the GTX 1080 or other GPU. Just have the faulty Display Port plugged in with the Display Port cable connected to the monitor. Also, if you suspect driver issues, connect the computer via HDMI or DVI and reinstall the display drivers again. You may need to use older drivers if the newest drivers are breaking your ability to use Displayport. I hope this saved you guys from all the effort and possible RMA's! Thanks for watching :)

Shannon starts up the HackRF to show some of it’s capabilities. Follow along and learn about this new software defined radio peripheral capable of transmission or reception of radio signals! HackRF - Getting Started and 2 Radio Frequencies at Once Pentoo, a Linux distribution with full support for HackRF and GNU Radio. Download the latest Pentoo .iso image from one of the mirrors listed at http://pentoo.ch/download/. Then burn the .iso to a DVD or use UNetbootin to install the .iso on a USB flash drive. Boot your computer using the DVD or USB flash drive to run Pentoo. Once Pentoo is running, type startx at the command line to launch the desktop environment. Accept the "default config" in the first dialog box and then launch a Terminal Emulator window using the icon at the bottom of the screen. At the time of writing, the current Pentoo .iso (2014.0-RC3) has a minor bug that you need to work around by typing "eselect lapack set 1" at the command line in the terminal window before trying to use GNU Radio. You only need to do this once after starting up Pentoo, but you'll have to do it every time you boot an unmodified .iso. To verify that your HackRF is detected, type "hackrf_info" at the command line. It should produce a few lines of output including "Found HackRF board." The 3V3, 1V8, RF, and USB LEDs should all be illuminated and are various colors. Now you can use programs such as gnuradio-companion or gqrx to start experimenting with your HackRF. Open GNu-radio companion via terminal and open the first HackRF map file. -~-~~-~~~-~~-~- Please watch: "Bash Bunny Primer - Hak5 2225" https://www.youtube.com/watch?v=8j6hrjSrJaM -~-~~-~~~-~~-~-

Get HD television shows with an over-the-air antenna! You'll get the know how to cut the cord entirely and you'll still be able to watch sports and live events! We're getting HD television over the air! Why? So we can completely cut the cord and still watch live events like sports and award shows. To pick an antenna, our favorite tool is TVFool.com . It gives you an incredible amount of data in one location. It might appear complex, but give it a read. Alternatively, you can check out AntennaWeb.org . It's a little more user friendly, but has less data. The antenna we used is the Channel Master CM 4228 8-bay HDTV/UHF Antenna CM4228HD . It allowed us to get signals from 40 miles out from the transmitter towers in the city. Use TVFool's information to direct your antenna. The right column shows where you should point your antenna. Directionality is super-important when you're far away from the transmitters. If you're in a city, it might be much easier to get signals in general. Use a compass or compass app to find the right direction. iOS Pick | Android Pick When you're using coax cables from your antenna to your tuner, use the shortest length of cable you can find as signal quality degrades over the length of the cable. We like using the HDHomeRun since it allows us to keep the tuner close to the antenna with short cables and then using our home network to carry the signals. E-mail: I just watched the video regarding making calls w/o a cell phone and wanted to make a suggestion regarding devices...it's cool to do this on a Nexus 7, etc but I bought a used Android phone on e-bay and set up Google Voice. i don't have carrier service, just use wifi and the Groove-IP app. Works great. - Nikkie Download or subscribe to this show at twit.tv/kh .

An oscilloscope can be made to display shapes by playing sounds into it. Making music from these sounds while simultaneously drawing images with those sounds takes things to another level. CLICK SHOW MORE In the video I fix up and put an old oscilloscope to a new use, and show how you can watch these audio-visual demos even if you don't have a oscilloscope by using a computer.

When NSA whistleblower Edward Snowden leaked details of massive government surveillance programs in 2013, he ignited a raging debate over digital privacy and security. That debate came to a head this year, when Apple refused an FBI court order to access the iPhone of alleged San Bernardino Terrorist Syed Farook. Meanwhile, journalists and activists are under increasing attack from foreign agents. To find out the government's real capabilities, and whether any of us can truly protect our sensitive information, VICE founder Shane Smith heads to Moscow to meet the man who started the conversation, Edward Snowden.
