Rclone is a command line program to manage files on cloud storage. It is a feature rich alternative to cloud vendors' web storage interfaces. Over 40 cloud storage products support rclone including S3 object stores, business & consumer file storage services, as well as standard transfer protocols.

Rclone has powerful cloud equivalents to the unix commands rsync, cp, mv, mount, ls, ncdu, tree, rm, and cat. Rclone's familiar syntax includes shell pipeline support, and --dry-run protection. It is used at the command line, in scripts or via its API.

Guppe brings social groups to the fediverse — making it easy to connect and meet new people based on shared interests without the maniuplation of your attention to maximize ad revenue nor the walled garden lock-in of capitalist social media.

I used to post to https://a.gup.pe/u/mycorrhiza.

This project represents a new attempt at the social link aggregator service. It is modelled after (old)Reddit, HackerNews, and Lobste.rs trying to combine the good parts of these services while mapping them on the foundation of an ActivityPub generic service called FedBOX.

It targets small to medium communities which ideally focus on a single topic. At the same it allows the community to reach other similar services and the rest of the fediverse ecosystem through the ability to federate.

feediverse will read RSS/Atom feeds and send the messages as Mastodon posts. It's meant to add a little bit of spice to your timeline from other places. Please use it responsibly.

Go is not an easy programming language. It is simple in many ways: the syntax is simple, most of the semantics are simple. But a language is more than just syntax; it’s about doing useful stuff. And doing useful stuff is not always easy in Go.

XahLee сказал:

the best languages to learn today for the next 20 year are: golang, PowerShell, Mathematica.

Про голянг понятно. Про остальное:

PowerShell or the pwsh, is far better shell than bash and unix bag friends.
Mathematica, is the programing language far beyond any other in the computing industry. A magnitude beyond all existing. It is more than a programing language, because it is really a computational knowledge base. Asides from math functions, such as solving equations or integration symbolically and hundreds other special math functions only a handful mathematician understands, it also embodies just about every practical algorithm in computer science. So, given a algorithm, you might write it in lang X for a hour or days, but Mathematica has it as part of the language, just call a function. Mathematica has few thousand functions builtin, not even needing to load a library.

A curated list of articles complaining that go (golang) isn't good enough

Not maintained since 2017. Nevertheless, the list is huge!

I get the impression that a map can only hold 64 values from this text, but this is not true. How does it work?

A wonderful read

TL;DR* It feels boring, it feels old, and as a consequence overly laborious. As a general purpose language, I feel D does the job a lot better.

The author applies the belts from martial arts to Go knowledge. I have the green one.

The author applies the Zen of Python to Go and tells us how Go programs should be written. This is a well-written article.

Perhaps the matter I most appreciate Go for is its long-term commitment to simplicity, stability, and robustness. I prize these traits more strongly than any other object of software design. The Go team works with an ethos of careful restraint, with each feature given deliberate consideration towards identifying the simplest and most complete solution, and they carefully constrain the scope of their implementations to closely fit those solutions. The areas where Go has failed in this regard are frightfully scarce.

Gophernotes is a Go kernel for Jupyter notebooks and nteract. It lets you use Go interactively in a browser-based notebook or desktop app. Use gophernotes to create and share documents that contain live Go code, equations, visualizations and explanatory text. These notebooks, with the live Go code, can then be shared with others via email, Dropbox, GitHub and the Jupyter Notebook Viewer. Go forth and do data science, or anything else interesting, with Go notebooks!

SQLite is a wonderful piece of software and it is completely meaningful to use it in a project written in Go even though SQLite itself is in C. Though people has been hitting lots of issues with it, mostly "database is locked" error that seems to appear out of nowhere.

First of all, SQLite allows concurrent readers but only a single writer. Unlike most places where you may encounter some sort of synchronization SQLite does not wait for the write lock to become available - instead it just returns an error, letting the caller deal with it. This is why you are getting "database is locked" errors.

Ebiten (/ebíteɴ/) is an open source game library for the Go programming language. Ebiten's simple API allows you to quickly and easily develop 2D games that can be deployed across multiple platforms.

And do I need to explain how bad it looks to have GitHub support baked right into your toolchain in 2020? We tried to warn you, folks.

Go creates static binaries by default unless you use cgo to call C code, in which case it will create a dynamically linked binary. Using cgo is more common than many people assume as the os/user and net packages use cgo, so importing either (directly or indirectly) will result in a dynamic binary.

Этот процессор может быть выполнен на транзисторах в домашних условиях. Схема строится только на логических элементах NOT, OR, AND, XOR, NOR.

This processor can be hand-made. The only logic gates the circuit uses are NOT, OR, AND, XOR, NOR. You can adjust the word size by adding more wires and logic gates in line with the circuit. The circuit provided here is a minimalistic 4-bit one with 155 logic components.

This is a collection of random thoughts regarding the application of permacultural ideas to the computer world.

Cheapskate installs an outdated OS on an outdated computer with laughable capabilities, yet somehow manages to use it.

Permacomputing is a more sustainable approach to computer and network technology inspired by permaculture. Permacomputing is both a concept and a community of practice oriented around issues of resilience and regenerativity in digital technology.

Rule of thumb: use POSIX shell.

This is a solar calendar system. According to the position of the Sun on the ecliptic, a tropical year (the time the Earth takes for one revolution around the Sun) is divided into twelve parts, which are known as the twelve solar months, numbered with the twelve Earthly Branches🪐. Each month is divided into two halves, the first named “Jie” (season) and the second named “Qi” (climate), totalling 24 periods, which are named according to the patterns in weather and natural phenomena that the ancient Chinese had drawn from their farming experience, and are now collectively named “the solar terms”.

Cognate is a small dynamic quasi-concatenative language for functional programming. Cognate aims to express complex programs in a simple and readable way through its unique syntax, which emphasises embedding comments into statements. This makes programs very readable and helps a programmer better express their intentions.

Now and again I go back to looking at the Damn Small Linux website. I never tried it but I absolutely love the idea. It was a desktop OS at only 50 MB, meant to include everything you may need on a daily basis. Of course it had to go with small scale versions for most things, but it packed no less than three different web browsers, two window managers, word processor, spreadsheet editor, pdf reader, and more. Wow!

HOT DOG Linux uses a custom lightweight Objective-C foundation on top of the GCC Objective-C runtime. The style of Objective-C is completely different from the one Apple uses, everything is basically id.

Here's a language that gives near-C performance that feels like Python or Ruby with optional type annotations (that you can feed to one of two static analysis tools) that has good support for macros plus decent-ish support for FP, plus a lot more. What's not to like? I'm mostly not going to talk about how great Julia is, though, because you can find plenty of blog posts that do that all over the internet.

Some reasons. They have not convinced me to care enough to enable it.

Psychologically, hoarding behaviour is rooted in fear, particularly of deprivation, or uncontrolled change, perhaps with unresolved loss or attachment to old patterns as a deeper cause. Hoarders can't move on. They cannot select what to throw out, because their value judgements are disrupted.

linkhut is an open source social bookmarking website.

The real problem with Internet addiction is that you know when you connect to it, often to check something particular, finding yourself two or three hours later without having accomplished anything but jumping from seemingly interesting links to catchy videos. Your brain is fed with low-quality content which has (mostly negative) impacts on your thoughts, your well-being, your mood, your productivity and your self-esteem.

Software like #Offpunk may help here by allowing you to never be directly connected to the Internet. You don’t use your computer while it is connected to the Internet. This means that you only consume content on your own computer, without being tempted to check if there’s anything new. Replying to a specific email doesn’t force you to see that new emails just arrived.

Besides the "offline" command, the "tour" feature of Offpunk forces you to read new contents in a linear fashion. And when you get to the end of it, Offpunk will tell you explicitly that this is the "end of tour". Yep, there’s nothing more to procrastinate on your computer. Move your ass and do something. The command line aspect allows you not to be distracted by the design and to be mindful about what you want to do. You need to type a command, you can’t click mindlessly.

Mastodon and Pleroma support four settings for post visibility. These are public, friends only, unlisted and direct messages. What actually happens when you use those settings? The only thing they will change are the to and cc fields of the created activity and object. Your server will federate the post to other servers depending on those fields, and hopes the other server respects this. There is no technological guarantee for this, though. A malicious server could leak all the data it receives. This includes posts to friends and direct messages.

The Screenless Office is a system for working with media and networks without using a pixel-based display. It is an artistic operating system. The office presents a radically alternative form of everyday human interaction with media. It is constructed using free/libre/open hard- and software components, especially for print, databases, web-scraping and tangible interaction. Currently, it exists as a working prototype with software "bureaus" which allow a user to read and navigate news, web sites and social media entirely with the use of various printers for output and a barcode scanner for input. While our existing software allows for interesting new ways of consuming media, we are currently working to expand the system to make it capable of publishing content and thereby, enabling a provocative possibility for active participation in contemporary social life.

They haven't really got anything to show, and the project seems to be abandoned. And using so much paper, I don't know, seems not so good. But cool concept! I want to learn more, but how?

To prove that this was indeed the mechanism responsible for the durability of the Roman concrete, the team produced samples of hot-mixed concrete that incorporated both ancient and modern formulations, deliberately cracked them, and then ran water through the cracks. Sure enough: Within two weeks the cracks had completely healed and the water could no longer flow. An identical chunk of concrete made without quicklime never healed, and the water just kept flowing through the sample.

I knew Roman concrete was cool, but not that cool!

"A good test case for whether a license is free (for issues like this) is whether a disconnected group of people on a desert island could distribute the software among themselves. In the vim case, they cannot. (For example, if the vim maintainer flies over the island and drops down a message saying "you must hereby send me your changes", how are the people down below to comply?) The fact that the vim maintainer can send the request does not say anything about whether the people receiving it could reply."

The venerable Dialog utility (based on ncurses, and maintained by the same person for the past couple of decades) is one option: a small program that can handle a variety of common interactions like choosing a file to open, or entering dates, while looking good and being easy enough to use.

It's the only friend that will store all of your thoughts years after your death and tell your stories to those who read it.
