> Why use blockchain? Why not just have the entity provide a database? Note that the standing may change over time.

The, "Why not use X?" argument seems to be repeated often here.

This is a really silly argument if you are using it to discount blockchain.

With most technology (nodejs, javascript, email on your phone, holographic video conferencing) there are usually alternative ways to achieve the same thing.

When email was added to phones some people said it was silly - their argument was why would anyone want to type emails on their phones when they have laptops already?

No one is saying that blockchain is the only possible way to achieve something.
Let me try to express that better: When we were just figuring out FM radio ourselves, i don't think we'd have been capable of recognizing a modern spread spectrum WiFi transmission as a signal. It would have been an elevated noise level and puzzling, perhaps.

So the next hundred years of human advance, I expect, will bring similarly transformative changes in the ways we communicate and the shape of our "technosignature".

Our expectations for what other species might be doing don't seem to be informed by the things we know we've done.
Tolerance to the euphoric and motivating effects builds much faster than a decade. More like a few weeks.

It’s a common problem with new ADHD patients. They mistake the euphoria and motivation for the therapeutic effect, then complain that it isn’t “working” any more and ask for progressively higher doses. Some eventually start doctor shopping to find someone who will prescribe higher doses when their provider refuses.

> With some advancements autonomous drones could be more precise and reliable than human operated ones

This is speculation at best, outright wrong at worst. Prove they're better than humans before employing them.
A 90% reduction in collateral damage is useless if the availability of drones means there are 10x the attacks, for example.
He seems to ignore Florida, Texas, etc who did just fine before the “technology” was ready.

Edit sorry to offend but his false dichotomy of five years of lockdown without a vaccine just rubs me the wrong way.
If talking literal fires, two, both cooking-related, frustratingly. :)

Tech fires can happen as often as 8-10 times a month in our work environment, which is consulting simultaneously for several clients. It usually happens a few weeks or months after information was not successfully passed into a larger organization and completely routed to the right people. The second most common cause is misconfiguration. We do cause analysis and often find that the person who misconfigured was very surprised at what they’d overlooked. Even the best-intentioned people cannot trust themselves if they’re busy. We find we have fewer issues when engineers are in the habit of including screenshots when they report having done something. The screenshots occasionally prompt a review from a colleague, but more often, the act of taking the screenshot or the glimpse of the screenshot when attaching it helps the engineer catch an issue.
This comment is so bleak it made me think of Amazon going the route of the US military and recruiting in high schools

Yeah, API uptime is crucial (and we spend a lot of time on just that). Though I think it's not just for us, but rather for almost all of the external APIs and services out there!

Nah, it's worse than that. Bringing morality into it would actually be better; it'd be easier to understand and rally against if companies were doing this because they were "evil". But they aren't, they're just greedy and want money.
My occasional accidental Google search for programming related things has been filled with spammy sites - I wouldn't quite describe them as "no content", but there really wasn't much of it. DDG isn't really better, but I definitely wouldn't say it's worse, at least for my searches.

Yes, backups, and Apple should get on that. However, your photos in Google Photos, your location data, your uploads in Google Drive (equivalent to iCloud Drive OP is talking about), not end to end encrypted and no option for it.

I think market share is another sign. Does anyone use actual Android Backup, or do they use the unencrypted “backups” in G Photos and elsewhere? For that reason should the FBI care? Maybe I’m wrong but I believe actual Android Backup is much less used than iCloud and confusingly named alternative “backups” within Google apps.

FWIW, nushell is much more of this than it appears. While many commands share names with Unix commands, that is the only similarity for quite a few, since they are rewritten to return structured data instead of text.
Nah. Humans can't fight cruise missiles either, yet it hasn't changed to where one side gives up when the other has cruise missiles.

The Brian Kernighan quote explains this very simply:

Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.

What if 90% of the populace retreats into simulations, but in such a way that the remaining 10% have no political power and no industrial base, because that all remained with the majority? Hard for the non-uploaders to expand in that case.
Not only should there should be no autonomous drones, the non-autonomous remote controller hardware should be wired up such that if they are shot out of the sky, this kills the human operator and anyone sitting nearby.

This would be much fairer than the current system of gamified point-and-click murder.
Amazon: “While we appreciate that some social media companies have become much faster at responding, to address this problem at scale it is imperative for social media companies to invest adequately in proactive controls to detect and enforce fake reviews ahead of our reporting the issue to them.”

Way to pass the buck Amazon. You created the walled garden. Do a better job of weeding it.
Ngn/k: a vector programming language
> It's not considered a "number" when society thinks of it in a higher conceptual abstraction than a number.

Which just shows that "number" itself is a conceptual abstraction, no higher or lower than the others.
I has nice building techniques, but unfortunately, it's all hidden behind a rather sparse exterior and doesn't look very exciting at first glance.

The playing features are cool (several stages that can be separated and put back together), but way too fragile to actually have children play with it.

It's a very fine display model, though. I've put it on a bureau right when you enter my apartment.

The ISS is superb, too (and rather cheap), but the new Space Shuttle was where I eventually drew the line. My pocketbook is very thankful for that.
It's identical to if you destroyed it. It just adds some risk that you might suddenly mobilize it (hence one of the reasons it's actually illegal for individuals to store large amounts of physical cash for long durations).

Also irrelevant anyway from point 1: you're still working to make money, thus you're growing the economy.
Do you mean that TimescaleDB 2.0 can be used instead of Citus to scale general purpose (non just timeseries) workloads?

For example a multitenant workloads where you shard by org_id, etc.?

I actually thought about it, but wasn't aware about v2.0
Well if you managed to deorbit yourself you've already broken all physical laws, so it's difficult to say what would happen after.
Argument-passing semantics (evaluation strategies) are something defined by the source language, not by the calling convention of the target architecture/platform. pdpi is right to point out that what the article is describing is not pass-by-reference semantics.

Unlike C++, C does not support pass-by-reference (ignoring preprocessor silliness). Passing a pointer by value is not the same thing. edit To be clear, C++ supports both pass-by-value and pass-by-reference.

Nice concept looking forward for release. Keep up the good work.
In about 15 years of being a developer, I have met a lot of difficult bugs in all categories of this list.

But there is another kind of bug that happened to me only 3 times so far, and that I definitely consider it to be the hardest of all.

It's when the language interpreter/compiler itself is broken.

This is a nightmare to find and understand because when it happens, nothing makes sense. You can take a break, have a whole night of sleep, have a walk or talk to a rubber duck, it still does not make sense because the logic itself is broken.
I'm not likely to bother blocking first-party images or other content so-delivered. Odds are I won't be bothered enough by those to block them, or if I am I'm more likely to abandon the site than to start blocking that kind of ad on every site.

The problems are the tracking and the ad networks that kinda treat both the viewer and their site-hosts as consumable resources, but that sites can't realistically avoid if they want/need ad support, because that's where all the money is. Break the ad networks, break tracking (and I mean legally, in both cases—tech means for blocking are doomed, IMO) and ad money won't go away, it'll be redirected to less-awful ways of delivering ads.
Ok, firstly - the orbital period is not given by the area of the orbit. It is given by the semimajor axis, by T = 2 * pi * sqrt(a^3 / GM).

So if you start off in a perfectly circular orbit, then you need to lower your perigee by the same distance as you raise your apogee, in order to maintain the same orbital period and meet up with what you jumped off.

The angle of impulse is easy in this case. It's perpendicular to the direction of travel. (For a circular starting orbit, and for a small impulse).
You’ll need the equivalent of this for your brand of smoke detectors:

How does this compare to the Cat language, which is also pure and statically typed?

Also, what "ring of complexity" does Stabel's type system live in, i.e. does it support rank-n polymorphism?
One important way testing environments and production environments necessarily differ is very germane to discussion of this problem. If you have an issue in 1 of 64 cores on a CPU on 1 out of 1000 CPUs, what are the chances your testing environment will ever see the issue? Do you have 10,000 CPUs in your testing environment? I know I don't.

At scale we really do need to think about monitoring, automated diagnosis, and recovery.
I understand that standards like these take years to make, but this should have been in the browsers for a loooong time at this point instead of every website implementing them differently.
This seems impossible to me without a bad actor being involved. How did you get stuck there in the first place? In one scenario you departed from a wall or hand hold somewhere and air resistance slowed you to a stop in the middle. In that case, you should be able to swim through the air given enough time.

In the other scenario there is no air in the space station, and as far as I can imagine, the only way to have gotten there with zero velocity would be for someone or something to place you there. Then presumably you could ask that same someone or something for help getting back.

There are some nightmare scenarios involving malevolent robots or rooms so large and velocities so slow that you would die before you made it to the other side that are pretty terrifying to consider.

This has been a bit of tug-o-war for me for a while. Where I've mostly settled is that I use TiddlyWiki as my main notetaker / knowledge base and using a paper notebook as a sort of sidecar (taking notes by hand where it is easier or more appropriate and then transcribing them into the wiki).

My wiki entries range from little "cards" of a few short sentences to longer entries written while analyzing or designing something.

I have switched to Neeva (neeva.com) which has no ads, because you are the paying customer. So far, it's been a great experience. I have had to get used to paying attention to the first few results, which are usually ads in Google or DDG.

While there is no privacy audit that I'm aware of, the theory is that there is no motivation to sell my searching habits to anyone.

DDG plans such a feature, but it will likely never be their primary revenue driver.
Amusingly, I have fast access to this pipeline (one of my childhood friends owns a generics manufacturer in India). But for tests, etc. sadly I am constrained to American gatekeeping unless I physically transport myself.

If the ship was intact, they were probably fine with water. A large ship departing harbor without a few months of water onboard would be the most egregious incompetence on the part of the quartermaster. If they were low on water, then you can be sure they would capture rainwater at the first opportunity, and in the tropics they would have to be pretty unlucky to get no rain. Also, this voyage is commonly done in 3 weeks or less. Africa to northern Brazil is the shortest crossing, and it's a downwind run the entire way. That said, if the ship was irreparably damaged anywhere off the NW coast of Africa, it _would_ likely wash up somewhere along the north coast of S America or the Caribbean regardless of the sate of the crew.
Autonomous weapons should be embraced, otherwise less scrupulous people will embrace them, and they will win. Non-autonomous weapons will simply not be able to compete long term.

Actually we wouldn't even be able to compete today, things like missiles are already autonomous, and if they weren't we would simply be unable to compete in any battlefield where radio was jammed, and it would give a large force multiplier to adversaries even in battle fields where radio is not jammed.
Interesting, but I’m not seeing anything on the Wikipedia page that suggests it was actually pagan (only that the original chant predates Christianity; not that there is any religious significance whatsoever) nor does it seem to have been Christianized by the Eastern Roman empire to convert people.

Yes, there are a lot of used typewriters for sale. I just did a search for "typewriter working" on ebay.com, narrowed it down to offers below $70 and got multiple pages of results.
In the context of Gravity this omission kind of makes sense, but the article ignores the ability of your ship to pick you up. The RCS of orbiting ships is extremely precise. As long as they know your relative velocity they'd be able to manuever back to you.

> At the moment, there’s no spacecraft to pick you up. The only one with a rescue-ready air-locked compartment—the Space Shuttle—is in retirement.

Then how'd you get into space in the first place in this hypothetical?
They seem to be only presenting the negative aspects of "slaughterbots".

Could they not potentially be better than human controlled devices since they should be able to more accurately target things and create less collateral damage?

Of course, there's always the doomsday terminator scenario where they go haywire and decide to start targeting all humans....
Technology accelerates change at an accelerated rate. While this could be beneficial to society, the main driver of innovation or creation of technology remains capitalism.

Guy Kawasaki has made some great points about how a business, founded in capitalism, should find purpose to make the world a better place. In many cases those changes brought on by a given technology isn't obvious until the technology has been adopted in a widespread way.

Facebook may "help" people connect and discuss important matters, but it also created a conduit (deluge) of information which hijacks people's attention away from things that may serve them better in the long run. It's when technology like Facebook, Twitter and other social media platforms push data to us that we give way, emotionally, to the influence.

When emotions get involved, attention is diverted.
> In Sanskrit Asura means evil people (demon), in Persian Asura becomes Ahura which means Lord.

Just want to point out that "Asura" does not mean evil in Sanskrit. In fact there were many great Asuras - Ghatothkacha, Barbareek, King Mahabali in whose honor we celebrate Onam etc etc. Asura if anything means materialistic, one who has not detached themselves from worldly pleasures. In point of fact, all humans today are Asuras by that definition

In the book “The Diamond Age” by Neal Stephenson there are mist-like swarms of nanobots that act as an immune system for regions against malicious nanobots.

I can picture there being something like this with drones.

There are problems to this. The major one being that, as mentioned by the posts on this thread, you have to develop the weapon to really know how to counter it.
We have hand held weapons to combat drones today. See

Our use case was OLAP workload and IIRC I don't think it's transaction support is great for horizontally scaling OLTP workloads. I wanted to call it out since the author mentioned timeseries data but didn't mention this aspect of Timescale. (Though to be fair, this feature of Timescale may have came out after the post was written.)

We can capture all known forms of interstellar radiation, we have a baseline of background noise, and we can see if they are chaotic or structured. I don't believe technosignatures are indistinguishable from noise.

I mean sure, sci fi mode engaged, aliens may have ascended our own physics and may use quantum entanglement or subspace for communications and the like, in which case we wouldn't know. And our own signals too will get weaker and garbled over time; I'm not sure if even our own radio broadcasts 100 light years away are discernible from the background radiation of all the stars.

One thing I've never truly appreciated until I started reading the Dolphin Blog [0] is the many nuances physical hardware has, AND how software developers often leverage these nuances (which aren't typically reproduced, for example, with an emulator).

Yes exactly. I believe Fortran and Perl only do pass by reference, for example.

It's not a C++ concept, I only used C++ in that example simply because godbolt.org makes it really easy to show how the language treats the two concepts differently even though they compile to the same thing.
Trawler fleets are huge and tow huge nets (or use floating nets). You can't really scare fish away because the volume swept by the nets is so huge. Driving off the fishermen is the only worthwhile solution.
I imagine that one should be able to profile the actual data from the actual web pages and then compile an optimal (or at least a near-optimal) decision tree, i.e., a decision tree with a minimum expected value of testing any of the inputs seen so far. Worst case is that this comes out as equivalent to the naive loop (the naive loop is essentially a degenerate decision tree), but average case should be much better.

Furthermore the decision tree needn't be binary. If you group regexes by common substrings and then even group substrings for, say, a Commentz-Walter matcher, you are able to distinguish N+1 cases for N patterns, with significantly lesser costs than N times the cost of matching for one substring alone.
