The Canadian Wetland Classification System (National Wetlands Working Group 1997) is based on a hierarchical system, which includes (1) wetland class, (2) wetland form and (3) wetland type. The five wetland "classes" are differentiated by their developmental characteristics and the environment in which they exist. The five classes are: bog, fen, marsh, swamp, and shallow water. Some wetlands accumulate peat (partially-decomposed organic matter) and are called peatlands. Bogs and fens are the dominant peatland classes in Alberta, although some swamps and marshes can also accumulate peat. In contrast, shallow open water wetlands and many marshes and swamps do not accumulate peat.

The bridge spider uses its web as an engineered “external ear” up to 10,000 times the size of its body, according to a preprint study posted to bioRxiv on October 18. The discovery, which has not yet been peer reviewed, challenges many assumptions that scientists have held for years about how spiders and potentially other arthropods navigate and interact with the world around them.

“Evolutionarily speaking, spiders are just weird animals,” Jessica Petko, a Pennsylvania State University York biologist who didn’t work on the new study, writes in an email to The Scientist. “While it has been long known that spiders sense sound vibration with sensory hairs on their legs, this paper is the first to show that orb weaving spiders can amplify this sound by building specialized web structures.”

But others in the field are pushing for a much more inclusive view: that sleep evolved not with modern vertebrates as previously assumed, but perhaps a half-billion years ago when the first animals appeared. “I think if it’s alive, it sleeps,” says Paul Shaw, a neuroscientist from Washington University in St. Louis. The earliest life forms were unresponsive until they evolved ways to react to their environment, he suggests, and sleep is a return to the default state. “I think we didn’t evolve sleep, we evolved wakefulness.”

Our neighbour is quite happy about him having a safe haven from the other cats. When he was bullied so much that he wasn't even left alone to eat in peace she gave us cat food to give him. Nowadays we just buy our own. I don't know if he ever eats there any more, but he surely eats at our house every single day.

Since the Hare programming language became public, it has been subject to some passionate criticism regarding a perceived lack of memory safety. I agree that memory safety concerns are very valid as shown by clear evidence, so the question becomes, should we write Hare off because someone online said it’s not strictly memory safe? I think that Hare can mitigate many of these problems today, while still being a small, simple and coherent language. let me explain how…

Electron and React Native Desktop are supposed to be a revolutionary new way of making desktop applications. Except they are not, and they eat up all the memory you have and still ask for more. They constantly crash and have no value over a native desktop application what so ever - well, perhaps with the only exception that now a 2 year old baby can make something shiny that you can click on with your mouse.

TL;DR: they get stuff done.

Japan operates with an Island metaphysic, where resources are finite in space (Japan is an island nation) but infinite in time (by virtue of natural regeneration). The West operates with a Faustian metaphysic, where resources are infinite in space (by virtue of conquest) and infinite in time. It's interesting to see these metaphysical realities manifest in something as ordinary as tool manufacture.

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.

Classic VK-inspired.

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.

UPD 2025. The page says the project is no longer actively developed.

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.

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.

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.
