To be perfectly honest I'm regularly surprised by techniques I don't know using plain old vi let alone Vim/NeoVim. That's still useful for situations where you only have say busybox vi.

I'm sure it's very well known but the "greatest stack overflow answer of all time" is an example[1] (IMHO obviously :D )

Vim Golf (also well known) is another invaluable and surprising resource[2].

I’m intrigued by this semi-throwaway* remark:

> Human feet are a nightmare for bipedal locomotion ...
The ostrich had a quarter of a billion years to master bipedal locomotion. What you get is a foot that an engineer would argue is a much more optimal...

The human door can perform many operations an ostrich foot cannot. There’s a “just so” factor to that of course: ostrich has iterated to optimize for a specific set of operations (mainly linear running as far as I can tell, with turning manifested by the hip). And indeed that would probably be better for humans…if that’s all they wanted to do with their feet.

The just so property is that of course we do those things with our feet because we still can, and in a little while (say a million years or so, maybe half that) we could happily abandon, say, the ability to climb a hanging rope in exchange for less foot pain.

But maybe not? The ability to dance, do ballet, make certain combat maneuvers etc may be desirable and selective pressure may not apply to the foot in the same way it did to the Dino-ostrich.

edit: I guess plants work too

You'd basically need to fit the entire food production capacity for each person inside a building to counteract the CO2 from breathing. Exhaled CO2 comes from food, so the same mass of carbon would have to be converted back into food or other plants.

Chemical scrubbing seems more viable, and might be a thing we start seeing in HVAC systems of the future.
This is possible by doing this:

git checkout feature
git rebase main

Why was this predicted a year ago by NGOs [1]? Do they have some special insight into this that cyber security specialists didn't? Are these kinds of supply-chain attacks at this scale new, or newly enabled? Is this a technically impressive attack, or is this just a bunch of backdoors?

What makes TrueNAS not consumer? It seems to have a pretty thorough interface for an open source project. Is it the price range? I'm asking because I'm weighing home NAS options now and TrueNAS seems like the best option. Synology is a close second, but they are moving towards hardware whitelists and have slow maintenance of packages.

OP here. thanks for the suggested links which I will try. I hope I don]t offend any open source folks here but this is commercial software with a EULA that clearly states the software may not be redistributed without written permission so it is a license violation and has cost me some $.

The premise that humans are smarter is appealing. The rationalization is big brains.

But my iPhone fits in my pocket and is more capable than a room filling ENIAC. SQL's "ORDER BY" is more efficient than writing sorting code myself.

Everywhere we look at computation, less is more sophisticated than more.

"Humans are the smartest" makes us feel good. That is a reason to question its accuracy.
More likely to be advanced technologies from U.S. forces than it would be adversaries.

Whether or not he agrees with the viewpoint he's paraphrasing is of no importance to me. I want to understand the point of view of people who think that way, in their own words. I have no interest in him filtering and watering it down to make it more palatable to you.

That's a very 1950s point of view.

Not even our generals are stupid enough to get in a war with China. (Our politicians probably are, but they're not in charge.) They'd probably take all of our Pacific Islands, and they would definitely sink all our carriers. It will take a few years for the Pentagon to forget the asskickings we've received recently. They're searching for nations smaller and weaker than Syria; China is off the list completely. Even though we spend far more on the military than they do.

However, we don't have to get in a war with China. We owe them trillions of dollars. We're probably not going to start out by straight-up defaulting, but there are all sorts of things we could fiddle with to put the hurt on them. What are they going to do in response? Stop exporting us lots of crap? That would be good for American workers. Maybe they'll hack American firms' insecure shit more? Ditto.

We would live happier, healthier, and more prosperous lives if we stopped viewing every challenge through a military lens. Especially since our military is incompetent to achieve any goal through military action.
It seems pretty snappy aside from the first page load (and refreshes, ...). Not perfect (some actions take a few frames sometimes), but not anything I'd spend more dev time on.

The first page load is nightmarishly slow. I tend to avoid services that pull in that much data because they're nearly unusable in low bandwidth scenarios (e.g., lots of stores or other commercial buildings made from steel, if you wanted to check a note while travelling, if your customers are among the 5-10% of the USA without home access to top speeds of >1MBps, ...).

As something of an aside, you're hijacking keyboard shortcuts that you don't actually use (at least, they don't appear in the help menu and don't seem to have any effect).

Also, it might be worth considering the privacy of the friend finder. When I add a username you instantly tell me their name if they're on your platform, even before they accept my request. On the one hand that isn't much different from twitter showing your name and handle together, but on the other hand that seems like surprising behavior for a note taking app, even one with collaborative features.
I too wish for this.

Some people are really great at writing commit messages, most are not. But for even for the ones who write the best commit messages, often their is a lot of discussion inside the actual MR which never makes it into git.

GitLab and GitHub write a merge commit that can be used to get back to that discussion, but a git blame or bisect doesn't take you to the merge commit, which means you have to spend a fair amount of effort to get to the merge commit.

Treating merges as a group would be amazing.

Something but addressed in the article is how you deal with groups of groups of groups of merges. IE topic, feature, dev, master branches.

It would be somewhat difficult to make the tooling graceful at ungrouping different levels of groups.
The author might enjoy `git rebase -i main`, which allows reordering, renaming, combining or pretty much everything in your own branch before you rebase and merge it to the main branch.

That way even if a commit message is not clear or you added an improvement to an earlier commit, you can reduce the clutter a lot before sending out for code review, while still having individual commits for different parts of the code change
Any POS terminal should be able to work with power only. There’s probably a dusty manual somewhere telling you how to configure it for the store to enable it and allow the cashier to type in an amount owing and then hand to the customer and queue payments for upload when network connectivity comes back.

Might lose some payments to overdrafts or cancelled cards. But they lived with that with credit cards up until 2000ish.

Buy-on-board on Aircraft and trains take advantage of this.

Offline payments is baked into EMV payments. It can at least verify the PIN and that the card was valid at its last phone-home.

Lolz, 'these days' as in making the argument to someone who would normally be against such actions that the economics increasingly tilt one way for rational actors. Obviously dealers on campus have been a thing as long as there have existed items to be dealt on campus. : P

But it's funny you bring up Feynman. I actually have it on very, very good authority that most of the LSD in the southwest for decades came from someone at Los Alamos who would put an eyes only sign on a lab for a project name that didn't exist to get privacy. When you combine that with the YouTube video of Feynman playing the bongos and singing about orange juice, along with his well known subversion of lab security rules... I'm not saying Feynman made LSD, but I bet he knew who did.
It's not only that. There seems to be a 'political' advantage to overconfidence even given the effect it ought to have on your track record. (This is not advice.)
lovely article! another one of those letters that weirdly fascinates me is Beta, in modern Greek it's pronounced as a V whereas when we read Ancient Greek we usually pronounce it as B.

There was an excerpt somewhere where one Ancient Greek author (unfortunately I have forgotten who exactly) described the sound sheep were making, and he did so writing the following:

Sheep make the following sound: βαί, βαί

which could either be Bae, Bae, or Vae, Vae... (whereas nowadays we would probably use an 'm' to describe the sound, as in Mae mae) - so while the sound is described, it doesn't really provide a definite answer since both seem somewhat possible. But maybe the author of this article could help us out here!

Rent seeking refers to economic rent, which is not the same thing as "housing rent". It has a very specific definition when used in the context of economic rent seeking. Renting out houses for people to live in is not rent seeking.
i think for the data center the key number is performance per watt. With smaller the power requirements go down. As the power goes down, heat goes down, so you can push the processors harder.

There are of course architectural improvements that improve performance with space to add gates etc, but when you have 1000s of chips cost of energy is the big thing.
I've been doing this my entire working career. I didn't realize it wasn't something everyone does!

When I worked in security, the first question I always asked was, "how would I defeat this system". When I worked in reliability, my first question was always, "how can I break this?". And now that I'm founder, I ask myself, "how will my business fail".

I know that the executives at a lot of large public companies have an annual exercise where they spend a couple of days just thinking about how the company could fail, what competitors could do that would be disastrous, and then what they can do to mitigate those things.

I also teach my kids these kids skills. When they build something I ask how it might break, or when they are about to do something risky I ask them how it might go wrong and what they will do to make sure it doesn't.
Well, perhaps they should just bring the cash then. I find it incredible naive to just do away with cash in society.

Yes it is, when you contradict something, you deny it.

I’ll assume you didn’t intend it as a denial and that this made an unintentionally ambiguous statement. We can clear this up easily with a clarifying question:

> Again: No technological breakthrough of any kind is needed to make viable the alternatives I cited. (This must be why you repeatedly try to divert attention from those alternatives.) All that is needed is scaling up already thoroughly-understood engineering.

What do you mean? I addressed the shortcomings of the alternatives you cited: Hydrogen has difficulties with large scale electrolysis. Ammonia is just the storage mechanisms for hydrogen, so it suffers from the same problem. You referenced hydrogen and ammonia here (https://news.ycombinator.com/item?id=27696690), so accusing me of diverting attention is rather strange. Compressed air can only achieve good efficiency if the compressed air is not allowed to cool down, which needs good insulation. Can you provide a source for the GW-scale compressed air project? Because all of the ones I can find are in the hundreds of megawatt hours [1]. Again, we need tens of TWh.

I think you're making the grave mistake of assuming semiconductor scaling applies to large infrastructure projects. This is very rarely the case for machinery and big physical engineering projects. Are we able to build dams for 1/1,000th the price as in the 1930s? Are we able to build jet turbines for 1/1,000th the cost? Or cars? We've had plenty of time to optimize and achieve the vast gains we supposedly achieve. Cars did see a sharp decline in cost, but it took a breakthrough to achieve that: assembly line manufacturing. And even then it was more like a factor of 20x improvement, not 1,000x.

Ultimately, we fundamentally disagree on whether is safe to assume that technologies in either the prototyping or demonstrator phase will become 1,000 times cheaper than the present options. I think it's unsafe to assume they will become viable at all let alone orders of magnitude better than the present options. Clearly you think otherwise, and believe in it with such conviction you accuse those who say otherwise of acting in bad faith. I don't think there's anything more productive to say here other that time will tell.

When I read articles like this, where the solutions proposed are to make it more efficient (legally, operationally, fiscally) for more people to live in smaller places, I'm curious how that resolves with others' sense of the desire for privacy.

I realize the privacy conversation here usually revolves around ad tech, but for me at least, it's more general than that. And I find that the denser the population, no matter how optimal it is, creates more constraints for me as a human being.

There's a sweet spot in the human equation for me, when I am the most liberty to enjoy self determination and free well, but also rub shoulders socially with enough of the rest of mankind that I enjoy the magnification that happens when we work together.

So I applaud efforts to get people in equitable homes--I have a married daughter who takes care of my wonderful wonderful 20mo grand twins, and I fear and angst for their future housing prospects in this country--but if they're just cages for rent in the end, did we really get the real prize?

Finley (YC W21) Is Hiring Senior Engineers (Remote)
Is there anything you can buy to reduce indoor CO2 levels without exchanging outdoor air? Is bubbling air through a tank of algae the only solution available to consumers? I'd love some product recommendations from HN, if anyone has one.
I agree. Many people essentially live in sealed boxes that only receive ventilation through cracks and the occasionally opened door or window. My home averages around 800 ppm and that is with a fresh air ventilation system that is constantly running to exchange the air. If I turn off the ventilation system, I measure CO2 levels over 1300 ppm within a matter of hours. CO2 levels above 950 ppm are associated with significant impairments to cognitive function.[1]

Economic rent takes its name from and is a generalization of land rent; land rent isn't just an example of economic rent, it is the paradigmatic example.
So when you hire a dev unfamiliar with your stack you risk having all that (bad engineering in genetral) plus all the possible mistakes they can do with the specific stack. Having good seniors on the team can mitigate this but honestly having people familar with your stack is a huge pro.

I don’t agree. People are hired to do a job. If they can’t do a job because they don’t have the skills and must depend on someone else to help them, they should not have been hired in the first place. This has nothing to do with empathy. This is common sense. If you can’t do the job, why are you here?
> C# does not allow returns from a `finally` block

I think C# does not allow any flow control in finally blocks, so no continue or break either (well for continue and break they're allowed if the statement they "refer to" is also in the finally block, but flow control can't go through or escape from the block).

Essentially in C# a finally block can only be escaped from by falling off of the block's end.

No matter how slimy CNET is (and that is very slimy) I don’t really consider it “stealing” that they downloaded something you specifically provided as a download.
