Do it! There's a dearth of such a format for the more "hi-falutin" topics out there. Doesn't need polish or total precision either, "us programmers" can deal with IRC-like stream-of-tid-bits.

Question: if compile-time evaluation of language X is fully-featured-fully-capable X (sans IO / syscalls, say) with "types as values" (of compile-time-only type `type`, say), ie. given Turing-completeness, where you can have functions that build up and return types --- do you still need complex theoretical type system constructs like "dependent"/"refinement"/"row-polymorphic" etc natively.. say at compile time, given sufficient prim builtins and storage-describing "prim types" (int, arr, tup) any further type-details are described programmatically. I suppose this leads to being able to express predicates that the type checker can "evaluate" in tandem with those compile-time evals..
Security issues, I think. Russia is very centralised, and many, many things of strategic importance are in the city. Many areas around it (near state residences, army bases, etc.) are also no-flight zones: https://img-fotki.yandex.ru/get/5902/214603206.b7/0_139f47_d...

Some source state that it is possible to fly over Moscow in certain corridors, but only on the altitude of at least 8100m.
I'm generally interested in this, but (even as somebody who knows intermediate Haskell), I don't have a good intuition about the scope of dependent types:

- how much of the burden of writing the proof falls on me, and how much falls to the compiler? I've seen Idris type signatures, and I didn't find them super easy to grasp.

- What are the full range of things I can express? What can't I express, even with dependent types? I come from math, so I'm used to have infinite flexibility to define what goes into my set of possible values. When I first learned Haskell I was surprised that I couldn't easily define types like "this set, modulo an equivalence relation". Or something like: "Int, but only even numbers".

- how huch more effort falls to me when structuring my code, in order to pass the properties or proofs through? I already run into this all the time in Haskell, with Maybes thay I _know_ to contain a value, or Lists that I know not to be empty. There is a real trade off between writing clear code, and wrapping/unwrapping values all the time everywhere.

Length-indexed vectors is a great example, because it is such a non-story in math, and yet for programming I have to front-load all this complexity to express something so utterly trivial. It's part infuriating, part enlightening how surprisingly tricky seemingly small things can be.

Monitoring Python Flask Microservices with Prometheus
It's interesting, but I'm very suspicious of statements like

"Without PFS, Neanderthals must have been simply wrapping the hides around their bodies like a poncho" or "As discussed above, building an animal trap is impossible without PFS"

Spiders can build traps without any language. Birds can build quite complicated nests without PFS. Yet we couldn't because we lack a particular language construct?

I'm pretty sure some things my dog does would be described as impossible without PFS by these authors :) Like burying a bone in one place when other dogs see it, then reburying it in another place when the other dog is in house :)

A lot of Nvidia's new RTX tech may be marketed towards gaming but it's actually having an impact in 3D rendering. Cycles supports RTX out of the box now and I'm sure other renderers will/do as well. And the denoising tech is amazing, while not up to the challenge on final renders it's perfect for getting a quick frame upstream.
Do you mind elaborating what kind of problems you work on?
Org-mode is awesome. But only in the context of Emacs. Markdown is less capable, but almost ubiquitous. I went from org-mode[^0] to markdown some years ago, and the only thing I am missing is org-tables.

Currently I am using a set of markdown editors: Ulysses[^1], Typora, iA Writer and a few others. That makes me interface agnostic. The most important thing is the content, the (markdown)text I am producing. I can't say that about text in org-mode. It's tied to Emacs.

(Edit:)

In Ulysses I started using an annotation system myself, that's why this project here caught my attention. I am experimenting with brackets, double brackets, colons, double colons. Still in the process of experimenting.

Looked at that in the past, for a more realistic experience you probably have to buy yokes like https://www.brunner-innovation.swiss/product/cls-e-ng-yoke/, which have more steps and do have force feedback. Unfortunately they are quite expensive ($1000 and up..)

What you see with Walmart is singular entity, owned by an obscenely rich family, who can strong-arm any supplier into accepting their terms.

They have the massive capital to build a megamart anywhere they want, and have it run at a loss for however long it takes to drive everyone out of business. This absolutely kills local businesses and funnels money out of the area, leaving only the low wages paid to the local Walmart staff. And because it's Walmart job or no job, people have no bargaining power.

When small businesses form cooperatives for collective bargaining, they keep ownership local, they keep jobs local, and they keep the stores in the city centres running, which is better for pedestrian and public transit access, not to mention cafe life and local bars/eateries. Compare this to a megamart outside the city where you have no choice but to drive there. You get everything there and have no real reason to go into the city. As a consequence, city life dies out.

Coops and associations work with the local shop owners and communities, whereas megacorps trample and replace them with cookie cutter faceless megamarts.

> The problem is that, as far as I can tell, there is no language with zero-cost dependent types, i.e. a language with dependent types that has a subset equivalent to Rust that compiles to machine code as efficient as the Rust compiler outputs.

The Coq language groups types into two categories: Set and Prop. Prop, which (informally speaking) contains all your proofs, is erased when you "compile" your Coq code into another language like Haskell or OCaml. This is something people have thought about quite a bit already.

I think the reason people aren't using dependent types has more to do with the ecosystem around these languages: the tooling, the libraries, the documentation, the tutorials, ... None of that is where it needs to be for these languages to be appealing to industry programmers.

> Hopefully Rust will evolve into it or a new language will come up for that: we really need this to finally have a programming language that is strictly better than all others and can thus be the single language in use and finally the solve the programming language problem.

I have serious doubts about this. Rust, like every mainstream language, already has too many features that overlap with what dependent types give you for free. Also, Rust is not a functional language (some people claim it to be, but there are side effects everywhere!), so it would be a bit of an impedance mismatch.

As much as I'd like to believe in this unicorn language that is better than all the others, experience has taught me to be skeptical of that. Programming is used to solve so many different kinds of problems that it's hard to imagine a one-size-fits-all solution, but I won't claim it's impossible.
It also supports VR. So you can go sit in an F/A 18c cockpit and click around. It is extremely immersive.

I watched some videos comparing ray traced and rasterised graphics and in real life the benefit seems negligible.
On top of that rasterised graphics use all kinds of smart techniques to improve the performance. Ray tracing the whole scene is kind of brute forcing, brick and mortar method. It should be used selectively and not on each frame IMO

Just a caveat that userbenchmark (while pretty useful) is banned on several hardware subreddits for _very_ questionable scoring methods, which seem to indicate bias towards certain manufacturers (most notably, drastic changes to CPU scoring just after the new Ryzen chips were released which seemed deliberately designed to keep Intel's enthusiast parts ahead). I believe their GPU benchmarks are more trustworthy, but I would skip them entirely still.

3Dmark is still fairly standard, and most reviews will include a suite of gaming / rendering tasks as well that can give much more useful real-world benchmarks. LinusTechTips is usually very good - e.g., https://www.youtube.com/watch?v=CoDPTJ-3qCM

I’m curious: in racing sims, in a three-monitor setup, the side view is extremely skewed due to perspective. They are there just to provide a sense of space and peripheral vision, but you’re supposed to look to the center monitor the majority of the time.

Is that not the case for flight sim setups? I can’t imagine looking at a horribly stretched image on a side window to be a nice experience.

The question then becomes whether a perfectly linear marginal tax rate is actually optimal in real world conditions [and if so, whether it's sufficiently optimal to warrant subsidising 8 million economically inactive people in order to encourage some of the 250k Jobseekers Allowance claimants out of their welfare trap]

In the real world [i] the effective marginal tax rate in for a UBI imposed in contemporary society is still going to be very steep (UK subsistence UBI ~£10k per year, median UK taxpayer under current system has a taxable income of ~£22k per year and many people on sub-median incomes are net taxpayers) and [ii] the conditionality of a benefit is a pretty strong reason to take a job, high effective marginal tax rate or not

The same can be said of drug dealers.

We agree that speaking words never kills anyone, but the same is true for selling drugs, still we can agree that drugs contain incredible destructive potential.

I feel like this is not an argument about the limits of free speech, it is about the validity of a specific argument.

Going more in a personal sense the existence of psychiatric theory and the significant help that people can obtain by "just talking" suggest that the opposite is also possible.

I do not think that the argument for free speech should be "all speech is always safe" rather it should be "this restriction will be misused in the future". Otherwise you are arguing for an anarchist position, which is fine, but it is not the status quo (or the status quo before hate speech laws)

You will probably want to spend your time doing fun things, but the moment you need to upgrade your car, your tv or buy that sweet new tool for your hobby you will need to take a job.

But the biggest benefit of ubi imo is that if you want to spend your time, say, building a new product or clearing your mind in order to be more productive in the future, you will have that option. Tho I do see a lot of people just sitting around doing nothing, and ubi leading to inflation.

Imo the best way to implement ubi is by automating as much as possible, to increase productivity, and to use the extra time and money to reduce the amount of work people need to put in for a living. Thus far automation disproportionately benefited employers and not the society and the workers, money wise. If a robot makes 10 times more shoes, then taxing that bot the equivalent of 5 full time workers is fair.

- graphviz is a more structured language

- graphviz is more mature

- graphviz can be used from command line
You disagreed with someone up the chain that the experiment's conclusions were "obvious".

- pick participants at random (regardless of employment status)
- give money to all the participants
