Why add holidays and sick leave to an individual employee's costs? Most white collar employees would have an annual salary this is factored into already, unless you're having to hire temporary replacements for them perhaps (which would be more than a 15% cost, I suspect).
I’m confused what the difference is. The lockdowns are a response to the pandemic.

If you’re suggesting the lockdowns are unnecessary or poorly managed that seems like a different discussion than this.

And if we want to cast blame I personally would blame, at least in the U.S., how little arts are valued - especially when it comes to providing arts education in public schools.

The federal government could be paying artists to produce work which could then be distributed free to help all of us as we get through this.

One of many possible paths not taken.
They don’t have to ask. These reciprocity agreements were made during the FATCA implementation process. People have filed Freedom of Information Act requests (local versions) in countries all over the world to identify how many records were sent back to these countries by the US and it appears the number is zero. Not a lot of reciprocity it seems.
It’s odd how it seems the US is capitalist on the way up, and socialist on the way down (for big co’s and industries
- airlines, banks, ect).

Good for equity investors. But - Individuals? We’re on our own.
A bit crony, in my mind.
If you don't mind me asking, how'd you make 80k passively? Investments, properties, or a "passive" sass/tech product?
Last time I worked with (on?) a payment processor we got special credit cards that worked like Stripe's test numbers for testing production. I.e. some cards would go through, others would fail with errors specific to each card number.

They were probably one of the most closely guarded pieces of equipment we had since the cards that cleared did so at any merchant so it'd work at point of sale but the vendor would never receive the money.
Rust is too complex. It's not simple like C
I would recommend reading the conclusion before dismissing this as "they picked numbers to throw at the Drake equation". The point of this paper is to provide modeling not only of the scalar output of the drake equation (which is... not used at all) but of the possible spatial and temporal distribution of intelligent life in the galaxy. For example, it turns out that even for wildly different choices of the unknowns, the region (and age) of the Milky Way that contains most life (i.e. that SETI should focus on) is the same.

Also, why do you consider "unknown" a problem when they explicitly set out to investigate the influence of these parameters? For example, they explore Pann of 0.0, 0.5 and 0.99 (per Myr). Could you explain what problem you see here?
The kinetic energy required to spin up a rotor mounted on low-friction bearings says very little about its efficiency.
I wish because I’m curious. You have to buy some aftermarket hardware for that.

And yes. Mostly luxury cars ATM but it’s growing.
I'd be curious to know as well. I'm someone who doesn't have an internal monologue or the ability to visualize images (I can hardly comprehend what that would even feel like), but I've never felt the need to talk to myself to think through something. I'm not sure I'd even know what to say.

For me, "thinking" is more like submitting a request to the subconscious and waiting for a response. Not much happens in the brain's "foreground"--or at least it feels that way.
> is not meant condescending but literally. Ergo, if you don't care about memory management (which is fine), then feel free to use lots of STL stuff.

I don't see it that way. Plenty of people care about memory management and also see the STL as a fine tool to use. Little is gained from a memory management perspective by avoiding e.g. std::vector. Whether condescension is intended or not, this definitely comes across as talking down to me, and worse, it is incorrect.
You store hydrogen in underground caverns. This is both simple and very cheap.

Hydrogen isn't flammable unless it is mixed with oxygen. That's the same with any other chemical fuel.

On the contrary: If you have a team member who no one sees fit to find praise for, it’s probably a bad fit. Praise doesn’t need to be superlative to be sincere. Not everyone has to be a “rockstar” to deserve positive validation.

While I agree using Github is a bad idea for a status page, using any machine on a home network is an absolutely terrible idea.
Good idea and fairly easy to implement from .bash_history. I never thought of it myself so I must be content with reverse search and grepping through bash history.

One suggestion would be to make it a homebrew recipe for macOS and the Linux version. It would then see a lot more adoption (even if the alias has to be set manually which is fine as it's personal). I'd install it instantly (and probably forget about it for a month).
I think you get destructive interference in some places (the ears hopefully) and constructive interference in other places (hopefully not the ears). So you’re moving energy rather than destroying it

Well, outside of when GH goes down, managing this in the cloud allows you to make more stuff 'serverless' - you don't have to worry about hardware failure and the maintenance burden that comes with moving stuff [data, code, secrets, logical volumes, etc] to a new host when you need to decommission the existing hardware. As long as you commit to the repo manually every few months (GH will stop crons on repos that have no commit activity), GH will continue to run your code on good hardware.
Even in Cortex-M, most array accesses are two instructions (lsls+ldr), as the ldr includes a "free" register+register add. For example, given an index in r0 and an array base address in r3:

lsls r0, r0, #2
ldr r0, [r0, r3]
Nothing about it sounds mandatory to me. It sounds like their team/company culture values recognition and openly & sincerely engages it as part of their schedule.
I don't think "more acceptable by other C++ projects" works out well. If I don't appreciate how RAII and exceptions clarify normal control flow, I won't write code that avoids leaking when its dependencies throw. This poisons any project it spreads to. Google famously had to abandon any hope of using exceptions because of a critical mass of flawed legacy code.
What do you mean by a life game in godot?

I wanted to make a game where the player can combine simple elements to create complexity. In this case, it's a 2D game where the player can "transport" humans and other animals like cats and dogs into the simulation. The player can confine the humans and other animals by drawing walls and fences.

Each animal in the simulation is an actor with a base set of rules that apply to all actors and a species specific set of rules that extend the base actor. For example, a dog will follow a human when they meet and return to the human when they are hungry. If humans meet they will share where to find food if they know of a location.

I'm still working on getting the game to a point where I feel like I can share it. The UI work was important for this because honestly my first attempt was not very good. However, I have reworked it and am much happier with it even though it is still very basic in appearance. At this point I am only using Godot's built in UI tools and draw functions rather than building from assets.

EDIT: I should probably clarify that the game itself isn't related to or inspired by Conway's game of life. It's more like the Sims or Sim Ant.

Also do you eat the mushrooms?

No. But I don't necessarily look for edible mushrooms. Usually what I do is go for hikes or even walks in my neighborhood and look for mushrooms along the way. If I find one I have not found before I take a sample for a spore print. Then I write up a bit of info on where I found it and if I was able to ID it.

(Could you be convinced to take up bird watching?)

I hadn't considered it but I can't see why not. My original motivation for mushroom identification was macro photography. My interest in actually ID'ing the mushrooms came later.

Bianca Giaever is my favourite story teller. She made a mini series podcast called Constellation Prize for the Believer magazine this year. I want to say that my favourite episode is "My Year with Franz" where she spends a couple of years listening to Franz Wright's (a poet) recordings which he made in the last years of his life. It is very moving and sad story. However, I am not 100% sure that this qualifies as a 2020 release, since its a re-release of her work and the original was released on 2019.

However, Crossing Guard (first episode in Constellation Prize) is also very good. It is Bianca interviewing a crossing guard and it gets very existential. I listen to it when I feel lonely.
Just a quick non-thought-through idea but would it be possible to build an index in a way that allows clients to download only parts of it based on what they search? I.e. the search client normalizes the query in some way and then requests only the relevant index pages. The index would probably be a lot larger on the server but if disk space is not an issue...?

(Though at some point you have to ask yourself what the benefits of such an approach are compared to a search server.)
It won't seem so bad if you can do this on an ultra low priority basis. Meaning that you could do a tape every time you are near your digitizer. Perhaps that is 5 times per week. 5 tapes per week would get the job done in 26 weeks.

There are also professional vhs digitizing services that might offer a bulk rate. I'm only assuming that because of the large numbers of companies specializing in 8mm film transfer to digital video.

I'm similar to this but differently. I did go on keto and it helped me tremendously. This has also made me "eat more like grandma". I eat "normal" again but in doing so limit carbs and eat more fat automatically.

Instead of the current everything is sugared into oblivion over-carbed food with fat reduced recipes I like to use grandma style recipes that start the recipe with: take a cup or two of cream and a block of butter (ok not really _that_ much but you get the idea). Tastes way better and needs way less sugar to taste good and I know exactly what's in it as a make it myself.
Given the population density, I'd bet that land in NW Ontario can still be had for a v.g. price.
Since my son has been remote learning at a desk next to mine I've been wearing noise cancelling headphones a great deal.

The skin around ears have been super sensitive due to what I assume is just the natural heat build up from wearing headphones and pressure on skin not used to having pressure on it all the time. The skin is raw and irritated.

It's not terrible, but not comfortable for sure and has been limiting how much I can wear any over the ear or even on the ear headphones.
I’ve heard that Go code can make use of libraries written in C++, but that you can’t write libraries in Go and use them from C++. Is that true?

If so, it’s a significant impediment to introducing Go into a team that’s currently using C++ - any Go code would be isolated from the rest of the codebase.
Regarding flying spheres, there's also electro(static) lift caused by Earth's electric field pointing upwards. The drag is microscopic, but some tiny insects have figured how to use it for flying. I wonder if a light sphere could use an electromagnetic motor to create a strong electric potential and use that to move vertically? In an ideal world, this electrostatic drag would also grow quadratically with the sphere size so it would be possible to lift a hundred kg with a reasonable sized sphere.

I think the discussions feature might be a little more comfortable for more people to express gratitude, but like you said even that isn’t explicit enough. I also feel disinclined to post gratitude for fear it’ll register as noise.

IMO since GH tends to be somewhat aware of how people piggyback their platform, a README gratitude badge might be a good place to start. It can be as simple as a button click plus an optional prompt to add commentary. In fact, I might make this a smol project to see if it gets some traction.
The problem of proprietary systems and single vendor lock-in are enough for at least some segments of the US military to ban their installation.

https://vrfrejected.org/case-studies/

The availability of multi-speed or variable speed compressor (inverter drive) is extremely limited in the residential market space outside of anything proprietary because there isn't enough cost flexibility. It doesn't help that American manufacturers are at least 20 years behind the Japanese and Korean makers on developing these.

It generally doesn't make sense for the manufacturers that have the tech to make open hardware systems for this market segment when you're only talking about $1000/ton for residential hardware. The lock in is more valuable than the initial sale is my guess.

I think one could likely home brew an open-hardware variable speed system by retrofitting a standard three phase compressor and variable frequency drive (see Jeremy Fielding's youtube channel—linked below) to their residential unit but it is hard to find a small enough three phase compressor and wouldn't probably be mass marketable because even single stage units are often good enough for most residential applications.

Future building code adoption will probably have an influence on this particularly in the areas where ventilation requirements are tightened.

Just find things the government can’t print more of, are desirable to a broad portion of the population, and are resistant to rapid increases in supply in response to demand. Gold, silver, bitcoin, land in desirable places. I also have the normal index funds and certain hand-picked stocks. One issue with stocks is companies can offer more of them in response to demand, unlike land or bitcoin.

We are in a period of rapid inflation but mainstream economists and the government pretend we aren’t. It has been going on for decades but the official inflation rate is supposedly sub-2% while healthcare, education, daycare, high-quality food, housing, and all manner of highly-desirable-yet-cannot-be-easily-created assets have gone way up in price and are unreachable to even the middle class let alone the poor.

Yet many applaud the “heroic” actions of the central banks and government when all they are doing is printing ever more money and patting themselves on the back. We as individuals need to act in our own best interests to avoid this disaster because no one is going to help us.
Are these examples of good products or are you making some other point?
Different credit limit and loan terms.
My “should” was intended in the sense of “I’m optimistic that they would find it”, not “if they don’t find it it’s because they didn’t try hard enough.”

“You should find carrots in the produce section”, not “you should wash your hands after sneezing”.

If I wanted to convey that tone I should have italicized it or used asterisks. That should have carried my intention more accurately.
Interesting project!

The fact that I have to fetch the stork.js from your CDN, and a random wasm blob gets pulled in as well, is unfortunately a deal killer for adoption, at least for me. A pointer to how to self-host might help address this.
True, although that cost gives you the ability to control the environment very precisely. This allows for a level of quality that people are willing to pay for, at least when it comes to flower.
Like the OP approved subset of C++, the design of Go is anachronistic on purpose, and makes a point to ignore most of what we have learned about programming language design since the 1990s.

Go goes further and puts the blame on its users, who are “not capable of understanding a brilliant language […] the language that we give them has to be easy for them to understand and easy to adopt”[0].

This stands in a stark contrast to one of C++'s design principles, namely that the language shouldn't “force people to use a specific programming style”[1]. C++ not being opinionated is not aesthetically pleasing, and at times confusing. But that wide acceptance to new ideas is exactly what allowed those ideas to graduate from niche languages to the mainstream.

Its a shame we don’t experiment with growing food in former bread baskets like upstate NY, Ohio, etc, and spend money on navel gazing exercises.

As it stands today, as a nation, the United States supply of vegetables and many other products is totally dependent on the Colorado river. A variety of problems from climate change to terrorist or other attack could rapidly impact our ability to feed ourselves.
While true it's also fewer branches than manual error handling via return values.

So the only "fast" option is to just not handle errors at all. Which is a terrible recommendation, of course.
Whenever I contemplate this, I always return to the notion of concurrence. Any sentient alien life we'd hope to encounter alive will need to exist at the same (relative) time that we do. The Earth is 4.5 Billion years old. Man has existed as 'man' for about 5 million years. That's 0.1% of the age of Earth. If alien species evolved in a similar manner, but 0.1% faster or slower, we'd miss them by millions of years.

I had an example of that recently: we’ve been buying grocery boxes from Hungry Harvest. They announced a new website was coming a couple of weeks ago and had the usually puffery about how it’d be better in vague ways (the old one was not noticeably bad). Then the site was down longer than expected. Then everyone was told their order customizations were lost. Now it’s so bad that they’re skipping an entire week’s delivery for all of their customers.

I don’t know how they got there but that’s expensive, disrupts their supply chain, and I suspect they’d cheerfully pay four times as much not to have to slog through this mess.

GCC isn't very clever about generating small binaries for embedded targets. Combining this with the code bloat from templates and heap allocator that must then also be linked into the program will make useful programs a tight squeeze in limited microcontroller program memory at the best of times. Dynamic memory management in long running programs with a small heap also invites fragmentation and spurious allocation failures.
A large part of the initial expense is right of way. Buying up/renting property or acquiring easements and defending the inevitable lawsuits is an ever increasing cost thats starting to rival the labor and material cost of the work. Maintenance is cheaper and will only continue to get cheaper relative to development costs unless there's a substantial change in the legislation governing that litigation.

>Environmental impact needs to be calculated as well.

The first comment on the articles page was addressing some of that impact.

Does it feed insects and birds and support biodiversity? Does it sequester carbon in the soil, making below-ground life healthy, increasing access of plants to nutrients, and hence produce healthier food? Does it help water infiltrate into the ground, this replenishing ground water and aquifers? Does convert sunlight into latent heat via plant transpiration, and thus support the Small Water Cycles that cool the surface of the earth and convey water (via rain) downwind to drier land? Does it engage the senses with beautiful sights and smells? Does it engage humans in an honest day's work, making them proud contributors to society?
Thankful. The few times I’ve been on a ferry or cruise ship I’ve been appalled enough at the amount of pollution to not do it again.

Yes, if you're on a team developing a program in C++, everyone should use C++
