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

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.

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---------------------------- Data Analytics with R Certification Training- http://bit.ly/2rSKHNP DevOps Certification Training - http://bit.ly/2T5P6bQ AWS Architect Certification Training - http://bit.ly/2PRHDeF Python Certification Training for Data Science - http://bit.ly/2BB3PV8 Java, J2EE & SOA Certification Training - http://bit.ly/2EKbwMK AI & Deep Learning with TensorFlow - http://bit.ly/2AeIHUR Big Data Hadoop Certification Training- http://bit.ly/2ReOl31 AWS Architect Certification Training - http://bit.ly/2EJhXjk Selenium Certification Training - http://bit.ly/2BFrfZs Tableau Training & Certification - http://bit.ly/2rODzSK Linux Administration Certification Training-http://bit.ly/2Gy9GQH ----------------------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 ------------------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

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

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

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.

a showing off video, nothing more. Music Adventures by A Himitsu from SoundCloud http://bit.ly/2Pj0MtT Sorry, audio (voice ) is not working great at the moment. Still making adjustments to new Linux OS. Also arrows do not draw the triangular part of the arrow. This is a font thing between Linux and winBlows programs. Just know a signal under price is a buy signal/above price is a sell. Standard DFX exit rules, wait for a clean close ( very little rejection) above/below exit level. As always much love to my testing team for which the indi is named after "Thusitha and Andreas" . Could not have made this without their ideas and input. Despite some kinks, Linux OS is working great. All traders...Windows 10 and their careless updates could cost you thousands. Their newest failure (update) disables mouse and keyboard at certain times which means you can not exit or enter trades. You must restart PC to fix. What can happen in that time on a chart??? LHP folks..all my methods are available to those who can prove ability to manipulate the primary energies used to feed the gods. Hail Satan, get paid :)

Video tutorial showing how to become anonymous, hide you internet traffic and identity, and browse the web freely without any fear of privacy invasion or any security concerns from your Government, school, or organization (NSA, CIA, FBI). Going off the grid and becoming fully anonymous (hiding your online identity) is not 100% possible, because of how the internet works, but we can do everything we possibly can to get as close as possible to anonymous. In this video guide, I will show you how to secure all of your devices--such as computers, phones (iPhone vs Android), tablets, and anything else, by securing your passwords, using two factor authentication, securing your web browsers (Mozilla Firefox & Tor), using a VPN (NordVPN or AirVPN), securing social media (Facebook, Snapchat), your communication like texting and email (Signal and Protonmail encrypted messengers), your operating system (Linux), and much much more! I will also cover deleting a majority of your online identity/fingerprint to hide as much information about you as possible, in addition to give you tips on how to prevent social engineering attacks. URGENT: This guide has A LOT of room for improvement, and I have made sure to update it. If you're interested in learning about EVERYTHING you need to know about security, privacy, and anonymity--check out Go Incognito, a free and in-depth course taking you from start to finish: https://www.youtube.com/playlist?list=PL3KeV6Ui_4CayDGHw64OFXEPHgXLkrtJO Now, some of you may ask why? Well, at a basic level, your privacy is constantly invaded by the websites you visit, your ISP, your government, your school/employer, and even services you use like Google or Facebook. Everything you do is being tracked and we aren't quite sure what consequences may result out of all of this data being created out of us. Some people also fear certain things like doxing, and other forms of leaks of your personal information. It is also common for corporations to sell your data for a profit, which is a complete violation of your privacy. This video is my 8,000 subscriber video, so I hope everyone part of the Techlore community enjoys it, and any newcomers decide to become part of the awesome community!

OK. So really you don't need to watch this video, just know this: Most decent gaming mice save the configuration in the mouse itself; that means once the mouse is configured it will work in any OS like Linux. This means you just need to boot up a Windows machine, install the driver software, configure your mouse, then you are good to go. Super simple. I wish I had known this before.

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.
