Interesting set of answers. I will jump to the most interesting one.

2) It's easier to think of Airbnb as a good idea now, but back then the idea that you could even make a business out of it was mind blowing. A lot of concepts that subsequents startups borrowed where introduced on a big stage by Airbnb. How you attacked 2-sided consumer markets. How you monetised it, .how a better UX than craigslist translated to a great, business,... And even YC back then was still a novel thing.

If you compare to the FlowClub-FocusMate situation. FocusMate had a good insight about the market, guts to go for it, good implementation, ingenuous BeachHead. They surely wheren't first to think about it but they delivered at a time when a lot of developpers fumbled around. And They were Genuine.

Which brings me back to my curiosity around FlowClub YC pitch. Do they have a particular insight about the market, or are they confident in their ability to outraise FocusMate ?

In 4) Could those be 2 different markets with one being 100x bigger than the other? I have no idea but seems small things like that could actually make a big difference. , I guess It's true and it it's woth a shot from the entrepreneur side.
But from my armchair, while doing some amateur quaterbacking, it feels weird to see the incubator with the most cachet pick the not genuine product. As if YC had backed studivz after Facebook came ( it's easy to say in hindsight of course ).

That's all true, but putting "humour warnings" kinds defeats the purpose, and converts what would be dry humour into something more akin to slapstick, a bit like that person we all know who always insists on going "Bah-doom, Tsh!" on every mildly funny aside. When someone else highlights things that that I no longer find them funny at all, so I'd be reluctant to do it.

I appreciate the feedback ... I think the best thing for me is just not to try again, and to be explicit when I know something is a joke, and clear that I'm adding factual information.

Watching people continue to downvote the comments I've made, HN is clearly the wrong place for me to do otherwise.
Yea, making it so statements are composing via YAML was a very poor choice. One case I had was needing to change my actions so that steps D, E, and F could be retried together. What is the github YAML specification for decrementing a 'tries_remaining' variable, then going back to a previous step? I couldn't find it, so ended up just having to rewrite the action so that most of the steps are now in one bash script.

Not being able to execute it locally has also wasted a lot of time, and people needing to make 50+ changes to the master branch until they get it right.
Well the op-ed is written by one of the founders of the movement conducting the lawsuit and their attorney, so I guess they wanted something arresting and attention-grabbing. I do hate now this kind of rhetoric style has become the norm though — it's just the perfect type of writing that's easily shared on Twitter/Facebook posts.
> Dam conflicts like this are nearly always across borders, not within border free regions like a country.

I don't think your assumption is true. Even just perusing http://www.worldwater.org/conflict/list/ I see plenty of intra-country conflicts. Heck, here's one in a first-world country 2 years ago-- https://www.watereducationcolorado.org/fresh-water-news/eco-...
I interpret them as saying “we think that because tribalism is a minor issue in the west and normally doesn’t surface, then we must generalize that it’s also a non-issue elsewhere” it is however, far from being the case.

> All cloud providers are required to, and do, make these scans.

No scanning is required by law. In fact, the law states you don't have to go out of your way to invade privacy to scan. So yes, you and tons of other people are missing a big piece in this.
> I link to one study, you say "Cherry Picking!"

No. We are talking about the article.

> that data is scarce

Nutrition science has been around for decades and people get PhDs in it. Like in most fields medicine there's always space to discover more but claiming that data is "scarce" is exaggerated.

> lacking solid information at a population level it's irresponsible to promote diets that may cause harm.

> To not advise people to do things that may deprive them of necessary nutrients, is the responsible thing to do.

There are millions of people in the world facing risks related to obesity like hearth attack and following other bad diets due to ignorance, or poor availability of healthy foods, or following absurd fad diets.

Of all irresponsible diet advice that can be given... you are clearly painting a boogeyman, like the article does.

That's very cheeky.

The author of this blog post uses the words engineer and engineering way too haphazardly. In my opinion, calling yourself engineer, when you are not a registered one, is a disservice to the actual engineers (that have to pass technical and ethical exams)

You could probably use it for ECM or EDM, but yeah, not stiff enough for traditional hogging cuts as a lathe or mill.
Yes, this looks like a great learning device! It could also be good for prototyping controls for a more serious tool, and the pen tool and maybe even a light extrusion head might produce some good results.

But cutting anything is, umm questionable.

In general, a cantilevered configuration is inherently wobbly compared to a gantry configuration that rolls on parallel rails/beams at the outside of the workspace. Even a massive Bridgeport-style mill has issues vs a moderate gantry CNC mill (although uses a lot less shop floor space). All the force paths are working to bend the cantilever device, vs all the gantry geometry that works to minimize error.

So, while it looks like a great effort and good for some things, if they want to offer any even slightly serious cutting capability, they'll need real work on the stiffness.

I haven't checked the exact wording of this definition but, as a summary, "The Supreme Court has defined public figures as those who hold government office and those who have achieved a role of special prominence in the affairs of society by reason of notoriety of their achievements or vigor and success with which they seek public's attention.

IOW: be conservative (in your decisions) and move like a tankship and not like a speedboat. Old is good. NASA does this too, AFAIK. They use conservative/old tech that has stood the test of time. (Lindy effect?)

That's the reason I won't switch to Rust from C++. I wait until it is matured enough and standardized. (Also, I wait until it makes C++ less relevant. It hasn't so far.)

C++ does the job. There's no perfect language or other technology. Many things have pros and cons.

Naval Ravikant also shares this sentiment, as far as I am aware.
> If I were them, I'd confirm this by "perf record" or eBPF and/or by disabling transparent huge page compaction

The report does look a lot like transparent hugepage defrag moving around memory randomly & system CPU spikes for no good reason.

And the workaround is valid, because THP can currently only map anonymous memory regions such as heap and stack space.

Literally the first thing I have to do to a Hadoop cluster is go around and turn off the defrag for the multi-threaded bits we have or system CPU goes over 20% as the system goes into workloads.

The other way you end up with a thundering herd causing permanent issues is with NUMA balancing (+ false sharing). So if you scale up a system slowly, you end up allocating in the same NUMA zone for a whole section (like a 1Gb array), which makes traversing it faster, but if this happens at the same time as another thread touching the same data, it will get scheduled over in a different zone & the kernel can do a lot of busy work with zone rebalancing as you go above 50% memory usage. This used to be a big deal when the first ccNUMA Intel boxes were coming out & mysql at Yahoo used to have so much trouble with NUMA messing up memory access speed assumptions[1].

The 96 core + 235GiB of data suggests there is some NUMA messiness going on for sure, particularly because there's a pinned worker to a CPU in the design.

The NUMA issues were front-and-center when the Power8 porting of Hadoop was going on , particularly because Java just gives you two things you can tweak directly in the GC (UseNUMA and UseTLAB). Because it was a lot of Cores on the bus (128 cores x 1TB - NUMA is like 1x-4x slower, which is hard to optimize for in a general sense).

Ask HN: How do run “hybrid meetings” where some are on-site and some are remote?
How do you manage to engage both on-site and remote participants in a natural and constructive way? Meetings that are either 100% on-site or 100% remote tend to feel much more smooth in my experience.

It wouldn't have been controversial just one generation in the past. For example, prior to the 1990s when this became technically feasible, people would have thought this was downright creepy and would have clamored to ban the practice preemptively.

It snuck up on us, or rather, it was quietly imposed upon us by profiteers whose meteoric growth was celebrated by all power structures.

>My evidence: nobody EVER bags Google Docs over its terrible DOCX compatibility. It makes an absolute hash of DOCX.

This is probably because most orgs that use Google Docs don't care about DOCX compatibility. But the vast majority of offices use MS Office, so Docx compatibility is a big damn deal.

But! I will say that I absolutely HAVE heard many, many people reference the lack of docx compatibility as a reason NOT to use Google Docs -- or anything else that isn't Office.

Even if we entertain your idea, though, and this isn't really a reason people don't use LO (even though it is), what then is the REAL reason people don't use LO?
I was under this impression that this was already known. Looks like this is from 2016, so I guess I was correct :). Perhaps we can add (2016) to the title for clarity.

In Germany we draw the line on what type of information the person in question makes public by their own choice. Do you invite tabloids for a home story and let them take pictures? Then other pictures of your home can be published. If you on the other hand never talk about your home and family publicly let alone invite media in, that can remain private. In addition, if the information is relevant to a larger topic (e.g. a corruption scandal involving a politician's home) then you can show anything relevant to that.

Ultralights and other small aircraft use a "ballistic parachute" to create a soft landing in emergencies. It's not foolproof - you can parachute onto a power line or into water - but it's (usually) better than a crash.

Safety isn't an issue for flying cars as long as they're as safe as regular cars. We have something like 40,000 deaths a year from regular cars, so flying cars don't have to be perfect.

(At least, they don't have to be perfect for social reasons. They may have to be perfect for legal reasons, to avoid the manufacturer being sued to oblivion. If they're not perfect, the crashes will have to be attributable to driver error instead of product defects, or they're gonna get mega-sued.)
I thought similarly - this is true if we can have lossless knowledge transfer. I imagine we would have to put what is learned into practice before translating it into distributed knowledge for a US fab workforce.

You're making the false assumption that there is a compromise to be made - but there isn't. A modern JSON library should be the fastest (or about the same speed as the fastest), and vice-versa.
In control terms it is. There’s a stable asymptote of ‘we made no machines today’ every day, until some external process breaks the dependency cycle.

AIRY3D has been developing a passive, single sensor depth solution that has lightweight power and compute requirements. With a single CMOS sensor you get both 2D and depth realtime streams. I work at AIRY3D and we have advanced prototypes with some samples available for eval/purchase (limited supply). Definitely could be a replacement for RealSense for certain applications (eg under 1 meter range, and ideal for outdoors).
I work with a bunch of senior engineers making 400-600k, I would say there isnt a huge difference between them and ones making 175k at a startup/non tech business. The biggest thing is comfort with scale, and high scale thinking. But its nothing thats difficult, just something to learn. If anything, I have seen much higher proficiency at startups where delivering across the stack is critical. Really, the interview process is segmenting engineers in ways that dont correlate with job performance (though there definitely is some signal)

That is simply not true. There is no American jurisdiction where child pornography is a strict liability crime.

On this topic, the Supreme Court has ruled in Dickerson v US that, in all cases, to avoid First Amendment conflicts, all child pornography statutes must be interpreted with at least a "reckless disregard" standard.

Here is a typical criminal definition, from Minnesota, where a defendant recently tried to argue that the statute was strict liability and therefore unconstitutional, and that argument was rejected by the courts because it is clearly written to require knowledge and intent:

> Subd. 4. Possession prohibited. (a) A person who possesses a pornographic work or a computer disk or computer or other electronic, magnetic, or optical storage system ․ containing a pornographic work, knowing or with reason to know its content and character, is guilty of a felony․

If one school out of 100 has a race-blind and merit-based admissions process it will quickly end up with way more discriminated people than the population levels of qualified applicants would suggest, because they are being actively pushed out of the other 99. That is probably how this high school ended up with a 70% Asian figure; I've heard the stereotypes about Asians and math but I doubt the differences are that big.

I didn't meant to imply it will perform worse than std::map. My point is that std::unordered_map has very particular design tradeoffs (primarily the requirement for arbitrary load factors and the bucket interface) that fundamentally impose large space and time overhead: Every node has to be stored as separately allocated linked list entry.

That's sometimes ok, particularly if you don't care about performance (beyond asymptotic behavior). But if you do, you'd probably be well-advised to try out hash map implementations that actually don't leave performance on the table by design.
If this ever gets expanded to handle clustering, it'd be perfect for me. I use k8s on my homelab across multiple raspberry pis.

> This study seems to say that these drugs don't change how you think (i.e., somehow improving the effectiveness of the thought process) but what to think about; what's most important, or not.

Consider that most people who are diagnosed with ADHD (especially if it was in adulthood) are well aware on the metacognitive level that they should think in terms of the benefits of work and its importance, and they do want to. Their problem is a difficulty to actively decide to think in those terms when it truly matters, in practical day-to-day life. So stimulants do indeed change how they think, improving the effectiveness of their desired thought process.
