I don't doubt your experience or even the countless others who have had it happen and shared online. I just find it possible to be a trigger-able hallucination. Similar to what is possible with drugs. It's impossible to ever know if an out of body experience is real or a hallucination. I do find it interesting though. I think meditation is a healthy process to keep in one's arsenal of activities.
> Boston was particularly bad about “what’s in it for me?” being the common theme of any conversation.

I'm really surprised to hear that said of the city where RMS wrote GNU while living in his car. Not my experience there at all.
Good point. Boeing should be have told every customer that bought a plane.
> At the same time, on the walls there were plenty of "american patriot" paraphernalia in the vein of "we say merry christmas here, and if that offends you fuck you". That makes it harder to feel welcomed.

Why should that make you feel unwelcome?

I'm also an immigrant, and have spent a decent amount of time in rural America, and my point of view is that it's wrong to hold Americans to a different standard than you would people from whatever country you're from. My family is from Bangladesh. If there were people going around trying to remove "Eid Mubarak" from the public discourse, there would be a total shit storm. 90% of Americans celebrate Christmas--tolerance for immigrants does not mean that people don't get to publicly celebrate their own culture, their religious traditions, etc.
In my experience, better tooling always wins in the long run.

I've built Debian packages in the past, and after packaging the same software with Nix, it's very hard to not feel that Debian tooling and packaging is time consuming for no good reason.
The nixpkgs model, where all you need to build everything is one `git clone`, all you need to make a change is a pull request and wait for a range of automated tests to tell you it's good (for both build and the _uses_ of a package!), and all you need to land a contributed change is click one button, seems strictly better.

Over the years I've heard many people say "but shell scripts, FTP servers and arcane helper tools is the way we've done it for decades and that will never change" in many projects, but eventually, these projects shrink and those with a good developer experience and clean tooling overtake them.

Similarly, after experiencing automatic, safe refactoring across billion-line typed-checked code bases, you can't help but wonder why people put up with spending their time going through heoric community efforts distributing work across people that a machine could easily do if you used good tooling.

In my opinion, the real strength and legacy of Debian is successfully running a large, diverse, distributed project over decades with (reasonable) cohesion, democracy, and (reasonably) good organisation and project management.

But even some non-technical problems go away with good tooling, and more time gets freed up to solve those hard tasks.

Concrete example: In nixpkgs it is very easy to build overlays for the whole of NixOS that allow you to switch from dynamic to static linking or add hardening flags across all packages, avoiding big debates over which is the "one true way" because providing both is so easy, and both can be merged upstream.

I think any big and successful project should continuously invest into better tooling, and simplify and automate things. That keeps contributors motivated and on board.

One thing I like about this analogy is the implication that some debt can make it harder to pay off other debt. It definitely operates in higher dimensions than just the two. I'm not sure about the implication that delivered features don't have a cost.
They were modelling a fluidized bed reactor.

The issue was their understanding of what the signal meant, they wrote a rather lengthy report full of nonsensical recommendations on basis of not properly understanding what the input variable represented.

As the years have worn on its gotten better. Still not great yet, and interoperability would be even better... but I have standardized on the 20V line from De Walt and have a number of hand, larger power, and yard tools that all use the same batteries. I buy a new battery or two every year and cycle out the oldest one (sell at steep discount on CL). Been doing that for 6 years now, and I don’t see them discontinuing the 20V line for years.
Do you have some sources where I can read more on this stuff? I came across stick maps when I visited museums in New Zealand, and found the idea very fascinating. I have an amateur interest in navigation.

But, having established that both were 737 MAX (”However, Sunday’s crash of an Ethiopian Airlines 737 MAX is the second fatal incident involving the aircraft type in just five months”) the observation that both were 737 MAX 8 is not surprising at all, given that >90% of 737 MAX’s in service are of that type.
It's mostly policy not technology that forbids this

If you control a name constrained subCA for example.com, then new leaf certificates can appear under there at your whim, but there are a bunch of rules that need to be followed for leaf certificates, so how do those get enforced? The root CA is responsible for ensuring they are.

One option is you could say OK, they just don't. So then certificates under these constrained subCAs are _worse_ than the rest of the Web PKI, why should we trust these subCAs? Clearly browsers should forcibly distrust them in that case.

Another option is, the root CA has physical control and all issuance goes through them anyway. But if you do this (and a few outfits have done it) then there's no practical benefit to the constrained subCA existing at all. It's just extra baggage.

According to the article, you may be getting more hair and be less susceptible to sun damaged skin. What isn't clear is whether or not taking melatonin orally at typical dosage (300 mcg to 5 mg) will have those effects in humans. It seems that most of those human studies used topical application, and several of the animal studies used melatonin implants. Also, here is a quote from one of the references (Kleszczynski and Fischer, 2012):

> Regarding clinical application, exogenous melatonin should rather be used topically than orally, since orally administered melatonin appears in rather low levels in the blood due to prominent first-pass degradation in the liver, thus limiting skin access. Topical application might be meaningful, since melatonin can penetrate into the stratum corneum and build there a depot due to its distinct lipophilic chemical structure. Therefore, endogenous intracutaneous melatonin production, together with topically applied exogenous melatonin or metabolites can be expected to represent one of the most potent antioxidative defense systems against UV-induced skin aging.
Titan – The 8 Bit TTL Processor
We have yet to encounter scaling problems that are best solved with custom algorithms; and only once in the last three years have we had a bottleneck related to computational complexity in our own code. We encounter scaling problems in general probably once every six months; most are solved by proper application of existing open source tooling.

Our codebase is chock full of business logic complexity, but very little of our code contains any meaningful custom algorithms. Maintaining that business logic complexity requires a specific mindset that's very different from solving or optimizing algorithmic puzzles.

Good CRUD developers aren't necessarily idiots or code monkeys who only know how to glue together Stack Overflow answers. But selecting for people who enjoy / are good at solving HackerRank challenges would just get us unhappy and ill-suited engineers.

We select instead for people who have strong software design and architecture skills and get a kick out of improving products and making end users' lives better. The result has been an effective, high-performing team with a high retention rate. So you do what works for you and we'll do what works for us.
Thanks for explaining. If they're just squeezing margin by being quicker, and not intruding into my trade (I don't trade. this is clear I think, given how ignorant I am) then I have less to worry about.
> California optimizes for people through various mechanisms

Except for high personal income tax, school funding, cost of living (food costs, utility costs, etc are all heavily affected by public policy), regressive consumption taxes (like the fuel tax), high sales tax, poor public transportation, and so on.

It certainly doesn't feel like California is trying to optimize for people.

The difference between GPL and BSD-like, to me , is that GPL says "what's in it for me?" Whereas BSD-like is "here you go take this for free, I may or may not got anything back for giving you my contribution."
> preliminary investigation said Lion Air plane wasn't airworthy before its flight and basically blamed Lion Air for poor safety processes

Your own links say no such thing, and directly contradict your claims e.g.:

> One of the angle-of-attack sensors on the airplane's fuselage was replaced after the airplane's penultimate flight - from Bali to Jakarta - after the Lion Air plane experienced malfunctioning data readings. Investigators therefore said the plane had not been airworthy during its last two flights.

How did you get from repaired to "wasn't airworthy?" Also the actual report doesn't "blame" Lion Air, it simply lists the facts. It is far too early to be assigning blame, and I'm sure there will be enough to go around (including the regulators themselves).
I think it is well-known that Polynesians, probably the greatest navigators in history, considered navigation to be a spiritual endeavour. I always thought that this is possibly where the whole "spice-eating space navigator" idea in "Dune" came from, but I have not been able to confirm this.
Can something be obsolete if it is still extremely widely used?

IIRC, Linux and FreeBSD both use a buddy allocator for physical memory, and I'm pretty sure it is used (in addition to other allocators) in jemalloc as well.
I feel like the debate on human induced climate change is a red haring. It's so abstract, it basically invites conflict and CO2 is absolutely nothing compared to issues of mass consumption. There are huge floating patches of plastic waste our oceans, being swallowed by sea life, killing fish and making its way into our food supply. There are massive lakes of sludge in Chinese and South Pacific factory cities used to make our electronics and PC components. There are disasters in the US like the Kingston Fossil spill where a coal plant containment damn breached and left a toxic slurry of coal ash and sludge flood the valley and enter the watershed.

Overall consumption needs to stop. Buying a new electric car requires all the waste that comes with making a car, plus the lithium and other metals needed for batteries that have to be replaced every ten years.

We cannot spend our way out of this. Humanity needs to consume less, to not replace cellphones and laptops every 2~4 years. Anything that fights real, tangible and easily measurable environmental disaster will also reduce CO2 emissions as a byproduct, but emissions themselves should not be and end goal.

The end goal is much much more difficult: convincing the people who run Intel and Apple and Samsung that it is in the planet's best interest to not have higher sales each year and that a better goal are products that last four times as long, where the sale of replacement parts are much higher than that of actual products. It requires fundamental shifts in the way our global economy works.

Anointed and Annotated, a Poem
Really depends.

If it’s a B2B product, just keep talking to everyone you know who is a buyer and try to get them to take a shot on you. If the product is far enough along to add value, make sure to charge. If it’s not, and you’re just looking for feedback, make sure to let them know you’ll be charging down the line but right now am looking for quality feedback.

If it’s B2C, there’s a lot of ways to hustle. From stopping people on college campuses, running some light paid advertising just to get some feedback, posting on product hunt, posting on HN, posting in response to related questions on Quara... etc, etc.

Sometimes meetups and networking are a good way to find early users. Talk about what your product does and hand out your card with a URL on it. Ask them to give it a shot and don’t be shy.

Once again, all depends. Without knowing more about the product it’s hard to be specific.
It'd be more correct to say pseudorandom. The way I was taught ZKPs was in terms comparing the output of pseudorandom number generators seeded by a challenge and a shared secret, but you can also explain it in terms of hash functions instead.

What I was thinking was that the random number from GPS (or some sequence derived from it) could serve as the challenge, basically akin to a 2FA scheme like HOTP. Or a variety of other schemes, hinging on the trait that you can't predict the next output of the random number from GPS.

> women are as much likely to formulate a biased opinion than men.

The point isn't that the researchers were biased, the point is that there was a monoculture of bias.
Because it will be inconvenient. It's like an unspoken agreement between us, "listen pal, if everyone does it, noone can be held accountable, and if you stop, it will be useless effort since everyone else will keep doing it".
The second statement is used very often to justify the lazy decisions our fragile mind takes.
I don't know of one central resource that covers all of these topics. There are good articles on jemalloc and tcmalloc that discuss modern allocation strategies for general purpose allocators. There are articles from games development that discuss object pooling both in the context of C++ and in the context of optimizing GC languages like C# and Java as well as other specialized strategies like bump allocators, frame allocators, etc.

Resources on learning modern C++ cover RAII and resources on learning Rust cover its approach. There are good talks on the fairly new polymorphic allocator model for C++ that cover the motivations for it and use cases. Experience with modern C++ is valuable for understanding how much you can do with mostly stack allocation and how you can write non library code without ever writing a raw new or delete.

> When an order hits an exchange, the exchange sends a flash order to the owners of the proprietary data feeds before sending the trade information out on the broader public markets, and making it available to all potential investors.

This specific behavior was only exhibited by DirectEdge (I don't recall if it was a registered exchange at the time, or just an ECN). The behavior was indeed scandalous because of the overt pay-to-play overtone, and was eliminated fairly quickly. Lewis somehow managed to mischaracterize all on-exhange HFT as this type of trading.
Not all the products are so loud, some are much more subtle and IMO better looking. But I also realize it's probably yet another class distinguisher.

World’s Biggest Mass Child Sacrifice Discovered in Peru
I have chronic insomnia, I had it all my life. I used to use melatonin but yes over time it lost its effect and melatonin is not one of those drugs you can just take more to sleep. It has a very precise dosage and if you take more it doesn't make you more sleepy.

If you have chronic insomnia, you need to solve the root cause. In my case it is anxiety, and currently I'm trying to solve my anxiety and my sleep quality improves as a corrolary.

Vaguely on topic: I used to work in one of the tall buildings in downtown Berkeley, so I could see the bay.

Every day, I’d spot at least one garbage scow hauling stuff off to be dumped somewhere in the bay/ocean.

That was about the same time they banned single use plastic bags. The hypocrisy of inconveniencing everyone to make a show of doing something while still allowing the garbage scow pisses me off to this day.

I wish these environmental greenwash programs came with a legal requirement to do a end-to-end impact study after implementation.
Typically, the way this is done is through a smartcard, secured and provided by state officials. A vote has to be signed by the key that never leaves this device. So even if you computer is infected by malware down to its USB firmware, it won't be able to fake many things. Just prevent you from voting.

My main criticism is that as it is it could still feed the card with the wrong vote to sign. The (state-provided) USB reader should have a small lcd screen to sum up the thing being signed "Vote for Ms.Ryjavik on election #123" "Vote for Yes on vote #432" and a confirmation button.

With these modifications, and the ability to check a cast vote has been received, you can have secure elections on insecure devices.

However it requires trust in the officials to do their jobs correctly and to not tamper the tally.

I, personally, love a lot of e-Estonia initiatives, but consider electronic voting to be a bad idea, unless you are ready to get rid of the anonymity of the vote (you can have secure non-anonymous remote voting)

For now you’d probably be right in some cases but not all. It’s certainly on the cusp of changing.

A petrol lawnmower still wins for long runtimes, though even that can be mitigated by having multiple batteries. It’s fair to say the electric upsides are marginal with mowers.

Whereas with hand tools like leaf blowers and line trimmers, the benefits are massive. Professional electric garden tools place the battery pack on a backpack so that the handheld component is light weight. They are quieter so no ear protection is needed, no sooty emissions so no face mask needed, and less vibration so it’s far less fatiguing for all-day use.
