My $0.02 on Is Worse Better ?
▻https://hackernoon.com/my-0-02-on-is-worse-better-e240784ed6a7?source=rss----3a8144eabfe3---4

There is a famous long-running discussion in software engineering that goes under the title “Worse is Better”. I’ve never gotten my two cents in, so I thought I’d talk about it a bit here. This is also an opportunity to try to apply the perspective from my experience with software development at Microsoft.This discussion was first framed by Richard Gabriel. He characterized the two different approaches as the “MIT” vs. the “New Jersey” approach. These labels came from the approach taken by the Common Lisp and Scheme groups out of MIT and the contrasting Unix approach coming out of Bell Labs in New Jersey. I found the discussion especially interesting because I did 4 internships at Bell Labs while getting my BS and MS at MIT. So I managed to cross over both schools of thought. Of course, Unix (...)

Is the Linux philosophy still relevant in 2019? | Opensource.com
▻https://opensource.com/article/19/1/linux-philosophy-poll

The philosophy outlined in these books was critical to the original design of Unix and its modern descendant, Linux. That groundbreaking design and its creative implementation made it possible for us to have the amazing open source operating system we have today. Without the concept of data streams, the use of pipes to modify and transform those data streams, the idea that “everything is a file,” and so much more, we would be reduced to struggling with a command line even less powerful than the old IBM or MS-DOS. Even DOS used pipes but never provided powerful utilities like the GNU Core Utilities that we take for granted today and give us access to the most basic of system functions.

pass, the standard unix password manager

#Password management should be simple and follow Unix philosophy. With pass, each password lives inside of a gpg encrypted file whose filename is the title of the website or resource that requires the password. These encrypted files may be organized into meaningful folder hierarchies, copied from computer to computer, and, in general, manipulated using standard command line file management utilities.

​Mosaic turns 25: The beginning of the modern web | ZDNet
▻https://www.zdnet.com/article/mosaics-birthday-25-years-of-the-modern-web

In the beginning, the web, or WEB as it was known then, was a mystery. Like gopher and archie, it was a character-based internet tool interface that only the proud, the few, and the early internet users knew about. Then, everything changed. First, the Commercial Internet Exchange (CIX) made it easy for anyone to get on the net, and then two graduate students, Marc Andreessen and Eric Bina, at the National Center for Supercomputing Applications (NCSA) at the University of Illinois Urbana-Champaign, created the first popular web browser: Mosaic.

Mosaic’s first beta was released for Unix operating systems running X Window on January 23, 1993. It wasn’t the first graphical web browser. That honor goes to ViolaWWW, a Unix browser, although some argue the even more obscure Erwise should get the credit for being the first web browser. The early browser Cello takes the prize for being the first Windows graphical web browser. No matter who really gets the credit for being the very first web browser, no one can argue Mosaic was the first popular web browser.

Speeding up the Build of C and C++ Projects

Many programmers know firsthand that C and C++ program builds very long. Someone solves this problem by sword-fighting at build time, someone is going to the kitchen to “grab some coffee”. This article is for those who are tired of this, and who decided it is time to do something about it.

If your operating system uses ELF format object files (Unix-like systems), you can replace the GNU ld linker with GNU gold. GNU gold comes with binutils starting from the version 2.19, and is activated by the flag -fuse-ld=gold. In CMake it can be activated, for example, by the following code.

Peter really (ahem) throws a light on many amazing luminaries from not only the Free/Open Source Software community, but in some cases the history and roots of all modern computing. He has managed to coordinate portrait sessions with many people that may be unassuming to a layperson, but take a moment to read any of the short bios on the site and the gravity of the contributions from the subjects to modern computing becomes apparent.

Intéressant cette notion de « communauté » des développeurs au travers d’une manière similaire de se comporter.

Everyone that I’ve photographed has been absolutely wonderful. I mean, that’s the first thing about this community: it’s a very gracious community. Everybody was very gracious with their time, and eager to participate. I think people recognize that this is a community they belong to and they really want me to be a part of it, which is really great.

So, I enjoyed my time with everybody. Everybody brought a different, interesting story about things. The UNIX crew from Bell Labs had particularly colorful stories, very interesting sort of historical tidbits about UNIX and Free Software.

Did your working in open source teach you anything beyond computer code in some way? Was there an influence from the people you may have worked around, or the ethos of Free Software in general that stuck with you? Working with this crowd, was there a takeaway for you beyond just the photographic aspects of it?

Absolutely! First of all it’s an incredibly inspiring group of people. This is a group of people that have dedicated, in some cases most of, their lives to the development of software that they give away to the world, and don’t monetize themselves. The work they’re doing is effectively a donation to humanity. That’s incredibly inspiring when you look at how much time goes into these projects and how much time this group of people spends on that. It’s a very humbling thing.

I don’t think it’s an obvious answer that Apple or Google or somebody else would have just come up with this without the open source [contributions]. This stuff is so fundamental, it’s such a basic building block for everything that’s happening now. It may be responsible for the golden age that we’re seeing now. I think it is.

The average teenager they pick up and post a photo to Instagram - they don’t realize that there’s a hundred open source projects at work to make that possible.

Lynx Users Guide v2.7

Bonus gratuit : Avec Lynx on est à totalement l’abri des scripts nocifs sur les pages web, enfin prèsque.

Lynx a un seul inconvénient : les pages qui ne marchent qu’àvec #javascript restent inaccessibles - mais ne faites pas confiance au message d’erreur qui s’affiche quand vous éteignez JS dans votre brouteur habituel ; assez souvent Lynx affiche joliment des pages web qui exigent du JS dans Chrome, Firefox et d’autres systèmes plus « modernes ».

Lynx is a fully-featured World Wide Web (WWW) client for users running cursor-addressable, character-cell display devices (e.g., vt100 terminals, vt100 emulators running on PCs or Macs, or any other character-cell display). It will display Hypertext Markup Language (HTML) documents containing links to files on the local system, as well as files on remote systems running http, gopher, ftp, wais, nntp, finger, or cso/ph/qi servers, and services accessible via logins to telnet, tn3270 or rlogin accounts (see URL Schemes Supported by Lynx). Current versions of Lynx run on Unix and VMS.

Lynx can be used to access information on the WWW, or to build information systems intended primarily for local access. For example, Lynx has been used to build several Campus Wide Information Systems (CWIS). In addition, Lynx can be used to build systems isolated within a single LAN.

web browser - Using Lynx on potentially malicious websites - Information Security Stack Exchange
▻https://security.stackexchange.com/questions/97873/using-lynx-on-potentially-malicious-websites

in theory, you are still vulnerable. Even in Lynx there are still components that parse HTML, interact with the network, keep track of cookies, etc (tip: use curl or wget to just download the page without even parsing it to be even more careful). That is still quite a big attack surface, though I would consider it safe enough at this point. Maybe not safe enough against a targeted attack from a powerful attacker, but definitely safe enough for random Android websites.

Deluge of Browser Security Issues Drives Mass Migration | Netcraft

April Erste, Public Relations Manager at the First National Bank of Oki Koki, told Netcraft that users are migrating to Lynx because of its speed and advanced security features. She added: “Lynx has not once suffered a buffer overflow in its image processing, and indeed has suffered no security vulnerabilities at all in the last 2 years.” By comparison, the most recent Firefox security update was only 4 days ago.

The bank also notes that Telnet remains popular with a small group of its customers. Although it lacks the sophisticated user interface of Lynx, many security experts argue that Telnet is significantly more secure and has the largest installed base of any browser.

Erste said that while the bank is dedicated to providing an accessible online banking experience, some customers still report difficulties when trying to make HTTPS requests through Telnet without the aid of an extended keyboard layout.

Who had an e-mail address in Soviet Union ? – Poussières d’empire

https://villesfermees.hypotheses.org/files/2017/01/CARTE-MAILS-URSS-01.png

This map was made with data extracted from the Soviet UUCP map, in its summer 1991 version. The Unix-to-Unix Copy Protocol (UUCP) refers to a suite of computer programs and protocols allowing remote execution of commands and and based on mutual cooperation. Reaching a remote computer in UUCP net required to know exactly the path data would follow. For example, reaching a computer located in Moscow from Novosibirsk required to know addresses of the machines the data would go through between these two cities. As the shape of the network was constantly changing, an effort rapidly emerged to build a map of the connections between machines. Each system administrator would submit, by e-mail, a list of the systems to which theirs would connect, along with a ranking for each such connection. These submitted map entries were processed by an automatic program that combined them into a single set of files describing all connections in the network. These files were then published monthly in a newsgroup dedicated to this purpose. The UUCP map files could then be used by software such as « pathalias » to compute the best route path from one machine to another for mail, and to supply this route automatically. The UUCP maps also listed contact information for the sites, and so gave sites seeking to join UUCPNET an easy way to find prospective neighbors.
In Soviet Union, UUCP map was managed by engineers working at the Kurchatov Institute for nuclear researches. They were closely working with people from Relcom, the first Soviet ISP.

The core of the OSMNames project is the pre-processed data. It comes in easy to handle text format, the #TSV (tab separated value). This allows filtering with UNIX text processing tools (grep, sed, awk, less, cut, etc.) and direct indexing via a full-text search engine.

The project comes with an open-source server software providing a place search API suitable for a basic #geocoder with autocomplete functionality. The server is written in Python and is powered by the high-performance C++ open-source full-text engine called #Sphinx Search.

Here you can download the pre-generated data with over 21 million place names for the whole planet.

Cron best practices

The time-based job scheduler cron(8) has been around since Version 7 Unix, and its crontab(5) syntax is familiar even for people who don’t do much Unix system administration. It’s standardised, reasonably flexible, simple to configure, and works reliably, and so it’s trusted by both system packages and users to manage many important tasks.

However, like many older Unix tools, cron(8)‘s simplicity has a drawback: it relies upon the user to know some detail of how it works, and to correctly implement any other safety checking behaviour around it. Specifically, all it does is try and run the job at an appropriate time, and email the output. For simple and unimportant per-user jobs, that may be just fine, but for more crucial system tasks it’s worthwhile to wrap a little extra infrastructure (...)

CIRCULAR VISUALIZATION

Circos is a software package for visualizing data and information. It visualizes data in a circular layout — this makes Circos ideal for exploring relationships between objects or positions. There are other reasons why a circular layout is advantageous, not the least being the fact that it is attractive.

Circos is ideal for creating publication-quality infographics and illustrations with a high data-to-ink ratio, richly layered data and pleasant symmetries. You have fine control each element in the figure to tailor its focus points and detail to your audience.
