Elon is able to develop these things because he is using his own money. In the US at least, Congress, the media, and the public would never allow NASA to use public money to blow up a series of rockets in pursuit of a working design.

The recent test flights of Starship prototypes is a good example. No one knew for sure when Spacex would have the belly flop maneuver mastered, but as long as no one gets hurt and he spends his own money, no one cares. Next they have to master successful launch into space, successful booster recovery, successful orbital rendezvous and docking, successful lunar landing, successful long-term life support, and successful high speed atmospheric reentry. All of these are very daunting technical challenges for a totally new spacecraft.

To be fair to Go, it provides an escape analysis log and a memory profiler in the standard distribution, so while fixing the heap allocations can require good knowledge of implementation details, finding out that you have heap allocations is really easy.
The first line of this essay talks about fish not existing either. For anyone interested in this subject (albeit from a different angle) I highly recommend the book “Why Fish Don’t Exist” [1].

It’s only really a little bit about fish, the founding president of Stanford (who was an obsessive ichthyologist), and his eugenics agenda. It’s also part memoir. I found it very touching and quite good 4 the ole empathy.

Right. Just like the force between opposite charges. That's how I've always thought of it.

Small nit - I think it is actually called electrostatic force, at least when we are talking about charges at rest.
In a Newtonian context, gravity is a force.

In an Einsteinian context, forces are not even discussed.
Sorry, I'm just unconvinced. There is no doubt that learning, for example, a Chopin Etude with the busiest hand alone is going to be a natural step before adding the second hand. Think about the reverse, would you expect someone who can play both hands together well to also be able to play them separately? Muscle memory does not disappear just because you add a second hand. The coordination does have some differences, but it's hardly a totally separated phenomenon.

I had a boss who liked to announce various new software features in email updates to clients, but frequently didn't bother to tell the engineering team to implement those features. I got tickets where a customer asked, "how do I make feature X work?" for a feature that didn't actually exist, so the task for the ticket was to create it.

At least Musk is just exaggerating the capability of an actually existing feature. On the other hand none of our missing features misled anyone to think that a dangerous device is safer than it is.

GMO's are not produced by targeted radiation in the way you have described, at least not as common practice (i.e. the GMO food you buy isn't created this way). GMO crops are generated in two ways: targeted gene modification (with deliberate modifications being made in contrast to the randomness of the radiation method you described) and crossbreeding (which has a more randomized effect but does not involve radiation).

If you look at the [Wikipedia article on genetic engineering techniques](https://en.m.wikipedia.org/wiki/Genetic_engineering_techniqu...) radiation doesn't appear once.
Elon is a personality, what the author gets right is he sets out by identifying the vision for the organisation, this helps to align the employees and customers in a way no corporate does (i.e especially not his competitors). Most corporate visions are poorly put together and sound similar “we want to do well to make our shareholders richer”. Elon’s vision involves humanity in its success, this is a unique differentiator. Elon has worked on building a controversial personal brand and as a result also put his companies in the lime light for free. Tesla and Spacex own a significant percent of the news today in their respective categories. He has disrupted corporate communications from the old faceless corporate PR to a champion of and relatable corporate personality.

The Inuit and Saami have lived on those diets for so long they became genetically adapted to them. The same is true for many Northern Europeans.

When they do not adhere to these diets they have worse outcomes.

https://science.sciencemag.org/content/349/6254/1343

So those diets are better FOR THEM, not for everyone. But the same could hold true for you or me. I know it is true for me because I have Saami heritage and the diet cures my hyperlipidemia.

No, it's nothing like that. It's a method for implementing interpreters that works well for Forth. It has absolutely nothing to do with 'spaghetti code' or structured programming.

In this case, the term 'thread' is the same in both usages. The confusion is that people started using 'multithreading' and 'threading' interchangeably. The concept of a 'thread' existed before Forth and any form of multitasking were invented, and MVT (which used the term 'task' rather than 'thread') and Forth were both invented around the same time.

I'd recommend you read the Wikipedia page for 'Threaded code': it's much clearer than the linked page, and will give some background of the purpose behind it. Most interpreters that don't do something like walking an AST do some form of it, even if that's by using some kind of bytecode. If you've ever seen code written using continuation-passing style, it's implementing a form of threaded code.

Works fine on opnsense.

But I'm pretty sure I've seen wireguard settings on pfsense a few months ago (non-commercial version)? So what is new here?

Btw, I'm wondering what HN folks think but I'm leaning to basically go full wireguard. I don't see why I wouldn't want it basically everywhere. It simplifies network management, makes things more explicit. There don't see to be any performance issues (running production database through it right now), and when running it at home it can even make my Internet seem faster when tunneling through it (probably because of some suboptimal TCP settings somewhere along the way, which seems common).

Interesting observation. I looked into it a bit.

Could theoretically be for Rust, but it sounds like Rust doesn't have the aliasing optimizations working yet. Based off [1], it looks like Swift's ABI might be able to take advantage of these things. (I don't know much about Swift)
Based off [2], it looks like Zig definitely can do these sorts of optimizations. Ada also has aliasing constraints, (you need to specify to the compiler that you want a thing to be aliasable) but I don't know if any compilers use them for optimizations. I know that Fortran can do these sorts of optimizations. Both Ada nor Fortran seem to be undergoing a PR renaissance, so they might be "trendy new languages" for that purpose.

However, given that the other two articles on the author's website [3] are about Delphi and complaining about AT&T assembly syntax, I'd suspect that the author is just a system's programmer annoyed about ABIs.

I agree with you. I have used Clojure many times in work environments because, well, that is what the customer/teams used. I also like Clojure, and am currently writing a short cookbook style book on Clojure AI projects. But, but, but: I am so much more efficient working in Common Lisp.

I think it is more about good software developers using the tools they love and getting good with them. Years ago, one of my repeating consulting customers brought me into a Clojure project where he had hired the Clojure Company Cognitect. One of their people (I think it was Stuart Sierra) was just incredibly productive. I think it was because of who he was and his skill set, not the language.

Several years ago, I managed someone who had non-computer science PhD, who was incredibly productive using Python. Was it Python? I don’t think so.

BTW, re: REPL based development (which is how I roll): I don’t much like Python, but I can’t imagine doing exploratory development not using Emacs and a REPL, in the same mode as using Emacs+Clojure+Cider. Different languages, same experience. It is the mode of development that is more important than the language.

I think your point on zero-sum vs. positive-sum is illuminating. Innovation is positive-sum. When games are perceived as positive-sum, people collaborate. When games are perceived as zero-sum, people compete. Changing the perception - not even the game itself! - has implications for how effectively people work together.

I really dislike how this article and popular media always criticizes capitalism in this respect:

> “without workers to exploit, the owning class can’t get richer. Capitalists cannot exploit the labor of the dead”

Working for a wage is not inherently exploitation, and it’s natural that if someone starts a business of any sort they will be the one who makes the most money since they had the idea and took the financial risk to start the business. If the workers don’t like the wages, there are options.

As it relates to the pandemic, I think it’s a case of business owners being ready to open but workers not ready to go back. Partly due to unemployment benefits (why work if you are getting enough money?) and partly due to a serious risk of COVID-19. Employers should expect to pay a risk premium right now and have that reflected in higher wages, which I would expect to come down over time as more people get vaccinated and as unemployment benefits begin to recede. If you’re trying to pay minimum wage you’re going to be in a very tough market and will have to raise wages or go out of business. In one respect, the least profitable (and perhaps least healthy) businesses will go bankrupt, which is healthy in a capitalist and free market economy. It also demonstrates the risk business owners take when starting a business. They might have dumped their life savings into a new business and had been reaping the rewards for a couple of years, but now they’ve lost that life savings whereas the workers lost nothing. Certainly this is a simplification of that process, but I think it’s generally applicable.

We really need to stop demonizing businesses in America. The issues we face are due to poor government and by lazy Americans who haven’t had to struggle for and don’t really value their democracy. The malaise and apathy I experience day-to-day from nearly everyone I know as it relates to government is exactly why we have so many problems. Everybody is talking about this business or that business and some workers and nobody can tell me who their representative is in Congress.
I'd second that list (Dan Abnett especially), but also add Sandy Mitchell's Ciaphas Cain books.

I can't even access TOR without VPN, because it's blocked in my country. My government makes sure our citizens use the best security practices to access the Internet. Very nice.
Sigh. Everybody in software believes they have some variable understanding of security but in most cases that confidence isn’t validated by anything. In most cases developers talking about security is Dunning-Kruger on full display.

Essentially every software security related subject can be qualified by a single question: What industry trusted process validates your concern?

I prefer to lean heavily on e2e/integration tests as much as possible, because I've found most bugs arise from the boundaries between discreet systems, particularly when they are developed by different teams.

However the point I was trying to make was more around super specific scenarios where a somewhat artificial test can highlight the possibility and prove that it's correctly implemented. As well as showing future readers that the code wasn't making an arbitrary decision but it was desired behaviour.

For example it's difficult to simulate rare/transitive failure states in e2e testing, but unit tests you can easily force these, and verify that they are handled correctly.

One thing that is tangential but springs to mind is when there are log statements that a monitoring system is observing - in these cases I'd add a unit test for that log line being emitted, not because I'm worried that the code doesn't work, but because I'm worried someone will remove it in future not realising that it was the backbone of some monitor

> but only the intervention group added 200 grams of sardines to their diet every week (two cans of sardines in olive oil)

So they significantly changed the macro nutrient ratios of the intervention group, along with the addition of sardines. I would like to see an intervention versus a control group with matched macros, to see if the effect is due to more sardines, or to more fat and protein and fewer carbohydrates.

In the long run it would've. It was mandatory to pay if you owned a TV. They tried to collect it for people having laptops / mobile phones but it was ruled illegal in the courts.

Instead the government replaced it with a new tax which seems more fair.
I will add here to clarify my stance on food and health.

There is no healthy food, only food that is healthy for you, and that will be determined by your genetics. Wheat is not healthy for celiac and short chain PUFAs and bad for me.

But too much of any food or nutrient can override genetics as well.
Or maybe you meant to say: A single abstract character (or code point) can be made up of multiple code units.

Unfortunately, the term “character“ alone is ambiguous because depending on the context it can refer to either code points or code units.

I don’t think people here dislike crypto for its stated goals, but because current implementations don’t live up to those goals and have some serious defects. The hype doesn’t match the reality, which makes crypto feel more like a speculative market than a solution to a problem.
“ In practice, the world is not divided between those who are sceptical and those who are not, but along the lines of what people are sceptical of. “

There is a lot of wisdom in this sentence. When attempting a reasoned debate, it is incredibly useful to assess assumptions and skepticism.

I often see a blind spot in reasoning when people assume that others are not skeptical about some domain.
> That's not the society I want. I don't want stronger doors everywhere. Tougher locks everywhere. Onerous security everywhere

> Digital borders exist all over the net. We use them every day to secure all sorts of things

Erm, how do you square these two sentences?

I took your first comment to be arguing against software security in general, presumably in favor of more post-facto enforcement when people violated authorization boundaries.

Your response then seemed to focus on mitigating the cross-jurisdictional issues that make post-facto enforcement hard, by having some sort of software-based security enforcement at a "border", and then relying on post-facto enforcement inside of that.

Now you seem to be supporting software-based security in the form of firewalls everywhere?

If we continue along this trend to even more local, we'll get to fewer firewalls (because they aren't that good of a technology), with security pushed out to the edges. Which is where best practices seem to be headed (BeyondCorp, etc), but is directly antithetical to your initial comment.

I remember on an podcast episode of Patrick O'Shaughnessy's "Invest Like the Best", his guest had mentioned the "villain test".

Essentially, it is summarized as "looks good, feels good." Whatever you're selling should have a noble call to action (looks good) but also have a more visceral, primitive appeal (feels good).
Tor is not anonymous if the relays and hidden service work together. Given the cost of hosting and the significant funding put into this by the U.S. it's just a matter of probability before the deanon cannon aligns to a user.
Mathematically all interactions can be described as fields. Where gravity differs from other interactions/forces is that it lacks, according to standard model but hypothesized to exist, a carrier (boson). Instead gravity is described by general relativity as the result of curved spacetime.

Edit: This is what article is about and how double copy helps with this. The previous is described in the article's second section.
Everything else (that we know about) in the universe is quantised. (I don't know whether experiments have shown gravity to be quantised yet.) If something's quantised, that means there's a smallest possible unit of it (a “particle”).

Yes, this. Of all the things I learned in SR, the example of two particles of the same charge approaching one another near c and the force vectors not lining up with the line between them was the most mind blowing. Instantaneously, conservation laws were violated, they held only over a “long enough” consideration of the interaction.

Newtonian mechanics is a useful approximation at certain scales. At other scales, they are problematic.
This is turns out to be rather straightforward once you realize that this is perfectly symmetric: it's just a matter of in which order you are revealing the colors. So this problem is exactly the same as looking at the first (second) ball, seeing that it's blue, then drawing a (revealing the already drawn) second ball. So there are two reds and one blue 'left'. So 1/3. (I am 95% sure...)
