An Introduction to Linux IPC Facilities
 
01:36:58
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

Linux User/Kernel ABI: the realities of how C and C++ programs really talk to the OS - Greg Law
 
01:25:45
Sorry for the slightly dark video - our screen recorder wouldnt work correctly for this talk so we opted for a wide shot including the screen. Hopefully this is still helpful and easy to view. All programs need to interact with the wider system in order to do useful work. C and C++ programmers typically write to the C library. It provides a mapping onto the OS that is a not-quite-perfect model of the OS underneath, and surprising behaviours can result. To be an expert programmer it is important to understand the ABI you are really programming to, for such times as you find yourself debugging via strace or without source code, fine grained profiling and optimisation, writing intercept libraries, etc. There are many gotchas. This talk covers how system calls are really implemented (int 0x80, sysenter, the vdso and the vsyscall page, and how return codes are translated into errno); how signal handlers really work (including the surprising syscall restart mechanism); how pthreads map onto OS primitives; the finer details of ptrace (the mechanism on top of which strace and gdb are built); and some interesting and surprising results when the subtleties of these various mechanism combine. Some of the other subtleties covered include what it means when things are in an uninterruptible sleep, and very useful info that can be gathered from the /proc filesystem.

How to Pull Images from Satellites in Orbit (NOAA 15,18,19 and METEOR M2)
 
14:24
Over the past 2 months, me and my friend Artem have been building antennas to receive signals from weather satellites as they pass overhead. This video chronicles our progress through this project and goes through some of the science involved in working with radio and receiving transmissions. We explore how dipoles work and how to build them, and how we built our final double cross antenna. We used an SDR (software defined radio) called a HackRF to do the work of interpreting the received signals and then decoded them with some special software. We pulled images from 4 satellites: NOAA 15, 18 and 19 as well as METEOR M2. The satellites broadcast immediately as they take the images and no images are stored, so we're likely the only ones on earth with these images. Prefer written instructions?

LINUX Understanding inodes
 
13:46
More videos like this online at http://www.theurbanpenguin.com Here we take a tour to make sure that we do truly understand inodes in Linux and what they do and contain. Firstly they do not contain the file name. This is stored separately and the file name is linked via the inode number to the inode. The inode itself contains the metadata about the file: the mode, ownership, size etc. Keeping the filename separate to the file metadata does mean that we can have then hard links, multiple file names that point to the one file by way of the inode. We will take a look at the ls command with the -i option along with stat and find -inum ; all of these command line tools help you gain knowledge and use inodes effectively in your system

Today here on Gadget Jeff TV we will be reviewing the cell phone jammer. This little nifty device will disrupt and jam cell and WiFi signals up to 70 feet away. Ultimately, making the victims phone unable to make/receive calls, text message or connect to the internet. Now before you get all googly eyed on getting one. It is important to realize they are illegal to use according to federal law. However, this law does not state it is illegal to own or use for personal decoration display (which is what I use it for) Each of the four antennas is responsible for blocking a specific cell band. CDMA, GSM, 3G/4G LTE and Wifi are all jammed by each corresponding antenna. When jamming all bands at the same time, this cell jammer will get you about 1 hour of use. When only jamming one band, battery life is extended up to 2 hours. (this is what I've read, not tested as I've never turned the device on) ;-) If you are interested in learning more about the beautiful traits a cell phone jammer carries and how being an owner makes you a very good person, simply search Google. There are plenty of websites that carry them. If you have any questions regarding this video or any of my videos, please feel free to comment below and I will respond quickly.

For more detailed Tutorial visit - https://goo.gl/bbvi0C A shell script is a computer program designed to be run by the Unix shell, a command-line interpreter. The various dialects of shell scripts are considered to be scripting languages. A shell usually interprets a single line of input, but we can also create a file containing a number of lines of commands to be interpreted. This file is a program known as a shell script. The program can also contain control structures (if-then, loops). Shell scripts allow a sequence of commands to be executed automatically . -------------------Online Courses to learn---------------------------- Blockchain Course - http://bit.ly/2Mmzcv0 Big Data Hadoop Course - http://bit.ly/2MV97PL Java - https://bit.ly/2H6wqXk C++ - https://bit.ly/2q8VWl1 AngularJS - https://bit.ly/2qebsLu Python - https://bit.ly/2Eq0VSt C- https://bit.ly/2HfZ6L8 Android - https://bit.ly/2qaRSAS Linux - https://bit.ly/2IwOuqz AWS Certified Solutions Architect - https://bit.ly/2JrGoAF Modern React with Redux - https://bit.ly/2H6wDtA MySQL - https://bit.ly/2qcF63Z ----------------------Follow--------------------------------------------- My Website - http://www.codebind.com My Blog - https://goo.gl/Nd2pFn My Facebook Page - https://goo.gl/eLp2cQ Google+ - https://goo.gl/lvC5FX Twitter - https://twitter.com/ProgrammingKnow Pinterest - https://goo.gl/kCInUp Text Case Converter - https://goo.gl/pVpcwL -------------------------Stuff I use to make videos ------------------- Stuff I use to make videos Windows notebook – http://amzn.to/2zcXPyF Apple MacBook Pro – http://amzn.to/2BTJBZ7 Ubuntu notebook - https://amzn.to/2GE4giY Desktop - http://amzn.to/2zct252 Microphone – http://amzn.to/2zcYbW1 notebook mouse – http://amzn.to/2BVs4Q3 ------------------Facebook Links ---------------------------------------- http://fb.me/ProgrammingKnowledgeLearning/ http://fb.me/AndroidTutorialsForBeginners http://fb.me/Programmingknowledge http://fb.me/CppProgrammingLanguage http://fb.me/JavaTutorialsAndCode http://fb.me/SQLiteTutorial http://fb.me/UbuntuLinuxTutorials http://fb.me/EasyOnlineConverter

C Programming Tutorial 6 - Intro to UNIX/Linux - Part 1
 
06:17
The goal of this video is to teach you how to do the most basic things inside of a terminal. Now, these commands are going to be the same for UNIX operating systems, like Mac, and also Linux operating systems, like Ubuntu. This is in a C Programming series, but we are not going to be doing much C for right now. That's because in order to be successful with C programming, we ought to familiarize ourselves with Linux. In fact, one of the biggest reasons C became so popular is because it was the standard programming language when UNIX gained popularity. So even if we are not talking directly about C, this content is still extremely relevant. Now, to start off, we should go over what UNIX and Linux are. As a reminder if you are a beginner, an operating system is just software that allows you to work with a computer and does things like manage input and output, memory, etc. Two popular operating systems include Windows 10 and Mac OS. UNIX and Linux are categories of operating systems. This means that there are multiple UNIX operating system, one of which is Mac OS, and there are multiple Linux operating systems, one of which is called Ubuntu. The difference between UNIX and Linux is not so important right now because Linux is a UNIX-like operating system. Because they are so similar, often people will be taking about Linux but really it can apply to UNIX operating systems as well. In these videos I am using Mac OS, which comes from UNIX, but it is going to be nearly identical for Linux operating systems. This means that if I say UNIX, you can assume Linux as well. Or if I say Linux, you can assume Unix as well.   Now one of the biggest thing Linux is known for is the terminal. If we are talking about people who use windows, very few people know how to use the command prompt, but with Linux nearly everybody uses the terminal.   The first thing you should learn how to do is the basic things you do with a mouse.   Just like you can navigate folders visually, you can navigate folders in the command line as well.   To figure out what folder you are in:   pwd   This location is known as your working directory. PWD stands for print working directory. This gives you the location of where you are, but how do you see what is in this folder?   ls   By the way, a more common name for folders in Linux is directories.   You can get more information with this command:   ls -l   The l is known as a flag and it changes the output of the program.   there is also:   ls -a   This is another flag. You can actually combine them:   ls -la   Think "list long all"   The very first thing you'll notice is that there are more files that show up. The files starting with a . are known as hidden files and don't show up by default. They're usually hidden for a reason so be careful touching them. The first section of this will list permissions. Don't worry about that for now, but notice the first letter. A D means it is a directory. That is how you tell if something is a folder or a file. Some terminals will also color code.   How do you change your directory?   cd directoryname   The directoryname can be considered an argument to the cd command. Arguments are separated by spaces.   One more thing I wanted to teach y’all. When you run ls -la you see two special cases. One is a dot and the other is two dots. The single dot refers to the current directory and the double dot refers to the parent directory. If you run pwd, you can see that the parent directory comes right before the current directory. So in order to move up a directory, you can run:   cd ..   Alternatively, you can pass in what is known as an absolute path:   cd /absolute/path   In the next video we will learn be learning some more useful Linux commands. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Synchronization 1: Semaphores
 
16:34
This video presents the first of several synchronization tools: semaphores. Semaphores (specifically, counting semaphores) allow processes to send signals and request access to resources. When a resource is not available, the process waits until a signal is received.

How to hack C/C++ Programs With GDB on Mac / Linux (for Beginners)
 
17:02
In today's video, I am going to show you how to use GDB (GNU Debugger) in order to hack a small C/C++ program we've made. The purpose of the #hack is to redirect the control flow of our program, from the normal functionality to a secret function that is normally inaccessible. Using GDB, we're able to see the disassembly of a function, we can see the available functions (using the command info functions), we can see the current status of the the registers (info registers), and so on. It is best to start with small steps, the smaller the C/C++ program you try to hack is, the more chances you have to understand the assembly printout. The C++ program I made for this video is available on my GitHub account for macOS, or as a source code if you wanna compile it in ELF for Linux. By the way, speaking about Linux, everything I did in this video is possible on Linux, with the same tools and the same commands. ▽ Resources ▽ ▶ The source code / macOS Binary: https://goo.gl/QCQrDA ▶ GDB Documentation: https://goo.gl/7wba94 ▽ Social Media ▽ ▶ Our Sub-Reddit: https://www.reddit.com/r/idevicecentral/ ▶ Facebook: https://facebook.com/fce365official ▶ Twitter: https://twitter.com/FCE365 ▶ Our Website: https://fce365.info

When Does Cable Length Matter?

PRECISION CW Fistcheck Description "This piece of software helps you to train your CW keying abilities. The program will show you what you are keying, mark and space, dots and dashes. It will even try to decode the Morse characters you have formed." http://www.qsl.net/dj7hs/help/helppcwfistchk.htm http://www.qsl.net/dj7hs/download.htm ZamGate CW KEYER: https://youtu.be/-uHSFcWW-qg SIMPLE SCOPE LV2 PLUGIN https://github.com/x42/sisco.lv2 JACK AUDIO CONNECTION KIT http://www.jackaudio.org/ NOTE: The PRECISION CW Fistcheck program installed perfectly on a LINUX LAPTOP using Lubuntu 16.04 with W.I.N.E. The PRECISION CW Fistcheck is using PULSEAUDIO for its W.I.N.E. audio input & audio output - which allows routing the input & output of PRECISION CW Fistcheck over to the ZamGate CW-REkeyers and Speakers/headphones NOTE: being able to see the SCOPE VIEWs helps you see the WHOLE WORD SPACING...and try to duplicate it with your STRAIGHT KEY NOTE: the STRAIGHT KEY is keying a 555 TIMER CHIP that outputs a sidetone that "keys" the ZamGate CW RE-KEYER
