What's a shell, what does it do, why would we need that? A shell is a program that acts as an intermediary between the user and the operating system, the kernel. It lets you execute commands on a computer. Specifically, on Unix, the shell is a command-line interface, a prompt that waits for commands entered by the user, interpret and execute them, and when its done, prompts again for a new command. It stays in this state that we call RE..

Understanding the Unix philosophy and what makes a Unix system Unixy. Let the good discussion flow, let all arguments and ideas be put down on the table.

We spend so much time typing at a terminal and yet the underlying mechanisms and history behind it are often overlooked. The TTY is an integral part of Unix, and we take most of its behavior for granted even though it has a huge history baggage that it carries to this day. For instance pressing control-C or control-Z to stop or put in the background a process, or using control-A to go to the beginning of the line. You might think that th..

System calls are one subject that scares many people. Actually most of the low level stuffs happening on the operating system scares a lot of people. I admit, I was a bit afraid of dealing with this subject. Not because it's hard or anything but because it's something that we're not used to dealing with every day, it's like a hidden magic spell. I was also afraid of dealing with this subject because I thought I could make mistakes while..

Everything is a file, right. Files on Unix have no specific format, nothing is imposed about how they should be, and there's no need to incorporate anything specific for them to be files. There's no file type, all the files are the same. But that's not really true. There are two differentiations. One is at a higher level, a meta level, using mimetypes which we discussed in an earlier episode about default programs. You can listen to it..

We've had an episode about display servers and libraries, and then we had another episode about window managers and desktop environments, and so the next logical step is to do one about ricing and customization. This is what we're going to do today in the company of xero, neeasade, and halfwit.

What would you say or give as advice to newly unix users. What is there first to dabble with. Today we're discussing advices and tips you'd like to tell newcomers. Remember the first time you laid your hands on a Unix box, most probably you were lost, just like most people. Now that you've got some experience with Unix in general what would you tell yourself from the past. Guests, thlst, abhx/stark

The world of licenses is the legal world, a world where the literal meaning of words is important and where all the crevasses are exploited. I'm not a lawyer, nor have I studied laws, and whatever I say will be based on what I understood from my reading. In this episode we're going to do a small overview of the topic of licenses on Unix. But beware, a "small" overview in the legal world is quite heavy!

Understanding how the fonts work on Unix isn't simple. I had never thought when starting this research that this field was this deep. Not only is it overwhelming, but the information around the subject is also not easily digestable. The last two weeks I've been researching this and in this podcast you'll barely find but the essential. It's still skimming the surface of the topic. If I explain something in a wrong manner, be sure to correct..

An executable is something that causes a computer to perform some tasks according to encoded instructions. It's in opposition to a data file which must be parsed by another program to be meaningful, for example an image or video. The instructions are usually in machine code, read by the cpu and so dependent on the cpu architecture. An executable once compiled will only work on a particular family of processor because the machine code ins....

A set of dynamic values, helper or configuration values, that can affect the way a process runs. Usually it's the process that queries those values, they are part of its "environment" and consequently the name. They are there so that the process can know the suitable values of the system it's running on. They are metadata, so to say. For example, the temporary location to store temporary files, or the home directory. This defintion is ..

You've certainly heard of daemons, those processes that lurk in the background and do what they're supposed to do. You might even have written and run programs that are daemons. Today we'll talk about them, those daemons ({day,dee}mon), what there is to know about their mechanism and details. A big generic overview of daemons on Unix.

At the beginning of time there was nothing... But that all depends on your definition of nothingness, what is nothingness... A power button is pressed, and suddenly BIG BANG... After a while, you get a Unix login prompt. Have you ever wondered what led to this, what happened behind the scenes from the time you pressed the power button until this prompt appears? In this episode we're discussing the boot process and what is specific to Un..

The topics in this episode are fairly simple, even basic, but I'd like to tackle them from a different perspective. The information in a computer is represented in binary form. For them the bit is the basic unit of this information. Bits are binary, and binary means that there can only be two states, or it's the first or the second state, nothing else. The CPU has some built-in commands to manipulate a fix set of those bits. The set of b..

I was born and raised in the Czech Republic. I learned to speak English and French in school. When I was 19, I moved out of the country and have been living in English-speaking countries ever since. Gradually, I have been losing the ability to speak my native language. This is especially obvious in professional settings (work, bank, government offices, etc) since I learned to be an adult while living in the UK. At this point, when spea....

Introduction Summary Back in January, a colleague pointed out to me that GHC did not produce very efficient code for performing floating point abs. I have yet to produce a write-up of my notes about hacking on GHC: in summary it wasn’t as difficult as I had feared and the #ghc folks were extremely helpful. … Continue reading Haskell for Numerics?

The next major version of NPM brings a number of improvements over the previous versions in terms of speed, security, and a bunch of other nifty things . What stands out from the user's perspective however is the new lock file. Actually lock files . More on that in a second. For the uninitiated, a package.json file describes the top level dependencies on other packages using semver .

But still, phew , it works.

Newcoder Scraping (Part 4) SQLAlchemy Session Basics Context I struggled with structuring database sessions in my python program. Reading through a few articles and tutorials on SQLAlchemy best practices, and studying Kenneth Reitz’s fantastic requests library, I realize I want a clean interface to the package. Kenneth does this by having an “api” module that wraps/uses the underlying classes/objects into neat little functions, so ..

Ten Haaf Project temporary, Geldersekade 30, Amsterdam June 2017 In this exhibition, three different scales of time are presented: elliptic(1), sluggish(2), looped(3). The Gait depict one being on a walk, each drawings being a step. All things, including the walker itself, are transforming at the point it is framed. A Man on The Bridge comes from a painting where one mysterious figure is walking down a bridge. In this publication..

750 words, 3 minutes. The Case For Default Deny What’s free, permanently reduces your exposure to a range of potential vulnerabilities, requires no maintenance, and takes only a few minutes to implement? Most web servers are installed to serve content to unauthenticated users on the Internet. Most only have a finite list of URLs or a specific number of web apps. I’ve always thought it strange that they install in a default-permit mode.
