This was an interesting read but I struggle to see the value in this study. Gendered language begets gender inequality, but so what? There's nothing (reasonably) actionable about this information. I have to imagine the time, effort and funds put into this could have been better spent studying what can actually be done about gender inequality in these countries.

As a big Next.js fan, this is a big release to me, React is my go to front-end choice and Next.js does amazing jobs server-side rendering and many other great things too, Now v2 supports Next.js out of the box means I can use lambda functions to serve SSR React for will save me a lot of boilerplates and maintenance work, so I will definitely check out Now again probably try few demo apps out...

But all great things aside, having Now v2 tied with AWS lambda means I will have to switch to AWS too. I like to stick with one cloud provider and my current favourite is GCP/Firebase, and I will have to weigh out the pro & cons of AWS/GCP again for Now v2. Hopefully in the near future, Now could be cloud provider agonostic
> And LMDB beats the crap out of SQLite, in any mode. http://www.lmdb.tech/bench/microbench/

Alright, I went through this page to see why my experience is different. While it mentions that they enabled SQLite's WAL journal, it also mentions that the synchronous writes were performed with PRAGMA synchronous=FULL.

I believe that if they set PRAGMA synchronous=NORMAL, they will get an ACI-reliable database that is way faster than LMDB with write-to-disk workloads.

Most of the measurements on that page are not really useful to me; they do not persist the data (db on tmpfs) or they do not care about reliability, using dangerous settings. Only few measurements are both persisting the data and writing safely, but the SQLite configuration is sub-optimal for them.

Can we ban companies from encroaching on ever more of our lives then? It's already a baseline to have it be one third of the working week, but many of these social events are "optional" as in it's optional to continue in your career.

By suggesting that companies ban taking part in that activity, but not preventing them from taking an ever increasing part of our lives through long hours and after work events, you are effectively advocating that we ban the activity in it's entirety
Haiku, unlike Mac OS, is barely known at all, even among highly technical and knowledgeable computer users. I'm a long term computer enthusiast and regular hacker news reader for many years and I'm just barely aware that something called Haiku exists (I'd forgotten until reading this article then vaguely remembered hearing about it before) and I certainly don't know it for its speed and ease of use.

I'm old enough and enough of a computer enthusiast to remember when BeOS came onto the scene. Even most computer enthusiasts today probably haven't heard of it and of those who have I imagine only a subset have heard of Haiku.

Now maybe Haiku really is great, fast and easy to use but I think it's a stretch to claim it's "known for" those traits when (perhaps undeservedly) I think it's more accurate to say to a first approximation it's not known at all.

In this regard it's nothing like Mac OS which while much less popular than Window, even my parents have heard of.

The point is aggregate demand is not that difficult to deal with, just look at say New York City.

Large data centers are huge building, the density is very much limited by heat issues and while the building might get bigger the power demand per square foot does not. We can move lots of power through very small areas consider individual steam turbines are up at 600 MW.

Even if we start talking about GW for a single datacenter, the single Kashiwazaki-Kariwa plant is already 8GW.
Sure - because cars have been most peoples only practical mode of transport for decades and it has become their default.

Now that scooters and ebikes are offering a very practical alternative to driving, cars no longer need to be the default choice when travelling and we can expect their use to decline.

I think something that most people don’t comprehend is just how HUGE space is. For context, at 550km orbit, the “surface area” of the sphere surrounding the earth is ~601 BILLION square kilometers. Suppose we had 40,000 (double the number of objects larger than a softball we have been tracking) objects up there, in that exact orbit, we would still only have one object every 15 MILLION square miles.

So, while it is a valid concern... until we put up “millions” of items, I think astronomers will be pretty safe. However, orbital debris avoidance... much bigger issue.

Constructive mathematics is the way forward. It's connected to linear logic via Chu spaces [0] (https://arxiv.org/abs/1805.07518). This correspondence is unreal as constructive mathematics / linear logic unlocks the door to several key advantages such as being closer to computation, probability theory, type theory, Lie groups, a generalized topology, optimization, “differentiable Turing machines”, all the quantum shit, game theory etc the list goes on.

[0] https://en.wikipedia.org/wiki/Chu_space

Linear logic is fundamentally about formulating computation as an adversarial relationship between two parties. It's also the foundation of e.g. the Rust ownership system (I know, I know, affine types).

It's also the foundation of the min-max algorithm which in turn is the foundation of Generative adversarial neural networks.

Ironically, this idea isn't exactly new. It's directly related to Dialectics (https://en.wikipedia.org/wiki/Dialectic) which has been present in Western philosophy since Aristotle through Kant, Hegel and Marx (it's a funny story).
I'm not sure that's a thing - PPL holders are supposed to be able to demonstrate flapless, partial power and glide (no power) approaches; plus low-level navigation. CPLs do more advanced (harder) versions of the same - it's part of most training curriculums and is tested on during exams.

We're experimenting with MSSQL's memory optimized tabled and native compiled stored procedures. My timings today, I was getting one call to our stored proc in the 300-400us range, that was inserting one record each into 2 tables.

Best performance so far ive been able to get from linux talking to MSSQL has been using OTL on top of unixodbc with MS Driver 17.

I am enjoying all of the comments here. I was lucky enough to study traffic-as-density-waves in younger days, and I think the future will be very positive. For this particular argument, I think the common themes to solve are lack of infrastructure, and the resulting safety hazards from casual users:

The setbacks:
The infrastructure currently does not support the reality of the populous renting scooters (and bikes and mopeds).
City planning was not developed around the recent technological availability of motorized personal transportation.
Humans are irresponsible, and will leave scooters in disruptive locations.
Humans are reckless, and a large portion won't abide by the established traffic safety.
This "last-mile" transportation movement is a result of public transportation being a poor experience: slow-moving, dirty, congested, mismanaged.

Positive thoughts:
"last-mile" transportation is highly effective if it could be implemented properly.
Proper implementation would require responsible user behavior and infrastructure compatibility.

An anecdote: The company Scoot, at least in SF, gave access to moped-like vehicles for casual commute. Great idea. Give people the ability to personally navigate dense populations without vehicle ownership.

The problem: driving a personal motorized vehicle in dense large-vehicle traffic is a major responsibility. For instance, riding a motorcycle is extremely dangerous, and the vast majority of motorcycle riders take their safety incredibly seriously. They vehemently abide by traffic laws because small mistakes can lead to major physical consequences.

Scoot riders have unilaterally behaved like inexperienced idiots in traffic. Running lights, making last minute decisions, and ignoring speed of traffic sensibility The casual nature of that commute style leads people to behave like they are on bicycles, when they are riding around already-frustrated car and truck drivers.

The same me-first attitude was clearly visible when scooters were widely available. Even with city permits, people are still selfish.

Solutions:

There are conscious decisions to make city-wide improvements in efficient transportation. Mass transit combined with low-impact personal vehicles would be a utopia. But no large city was designed with that reality in mind, and the "disruptive" companies that make these technologies accessible, often with the "ask-for-forgiveness" mantra, are very disruptive to both the pedestrian reality and the detriment of too many cars.

Tl:dr, people are selfish and reckless, and even smart and available technologies will be abused unless infrastructure is designed to handle human habits.

> Someone looked through a drone cam at a crowd of women and children, and authorized the drone to fire.

No they didn't. Cite a source for that. Don't just editorialize nonsense.

> If he didn't bother looking closely enough to identify his target, that's negligence or incompetence. (Middle Eastern women are noted for dressing distinctively.) If he didn't care, that's intentional murder, or whatever euphemism we're supposed to use in those circumstances. If he was told it was all right to fire without being able to see the target clearly, that's bad policy. If he was told it's all right to knowingly kill women and children, that's also bad policy. If the drone was authorized to fire without any human in the loop somewhere, that's really bad policy, and also bad tactics--there's no point in wasting a missile on an empty field that you expected a terrorist to be standing in.

> There is no circumstance where someone wasn't lethally and unnecessarily careless with innocent lives. Whether it was due to malice or incompetence is not really relevant.

People like to make silly statements like this, maybe for rhetorical effect. Whether or not something is attributable to malice or incompetence is always relevant. Mistakes happen in war. This may well be an instance of that. But it is not evidence that the policy is net bad. There are hundreds of these strikes. Some of them will kill civilians, but sometimes it's worth killing a few civilians to kill some unusually bad actors. We have people who's job it is to make that tradeoff. Do you have evidence that they're doing so poorly?

> Yes. You've already been linked to relevant articles in this thread. Do your own homework.

Firstly, the wedding that got bombed twice was not by drones, it was by jets. So, if the point of this thread is to discuss drones, it is irrelevant. There have been many wedding strikes, which one are you referring to?

> You are not going to Socratic-method anyone into admitting that, yes, it actually is okay to blow up a wedding if we think there might be a terrorist in there somewhere.

What, exactly, is the terrorist density of a wedding that makes it bombable? 50%? 80%? 99%? Do you know what the terrorist density of these particular weddings were?
> But why do they insist on deploying in areas where scooters are not wanted? Why not focus on the areas where they are most practical?

Because the most population-dense areas (NYC, SF) also happen to have the highest density of VC investment money.

I agree with you all the way up until here! I live in Miami, where single-passenger cars are king. Scooters would be great here. But the cities that would benefit most from scooters are not exactly overflowing with investment money.
> The premise that nuclear is inferior compared to wind or solar in terms of safety or cleanliness is wrong (especially with the current generation of experimental reactors), it is just different.

There is no long term storage option for nuclear power in the US. The ability to recycle it is questionable at best. If you want to build nuclear, I wholly endorse it, as long as you provide both functional waste recycling facilities and storage repositories before you load one pebble or rod into a reactor core. As of today, recycling wind turbines and solar panels is feasible, and failure scenarios for both are benign. Recycling of batteries from utility scale storage systems is also readily available through existing supply chains.

"The United States has over 90,000 metric tons of nuclear waste that requires disposal. The U.S. commercial power industry alone has generated more waste (nuclear fuel that is "spent" and is no longer efficient at generating power) than any other country—nearly 80,000 metric tons. This spent nuclear fuel, which can pose serious risks to humans and the environment, is enough to fill a football field about 20 meters deep. The U.S. government’s nuclear weapons program has generated spent nuclear fuel as well as high-level radioactive waste and accounts for most of the rest of the total at about 14,000 metric tons, according to the Department of Energy (DOE). For the most part, this waste is stored where it was generated—at 80 sites in 35 states. The amount of waste is expected to increase to about 140,000 metric tons over the next several decades. However, there is still no disposal site in the United States. After spending decades and billions of dollars to research potential sites for a permanent disposal site, including at the Yucca Mountain site in Nevada that has a license application pending to authorize construction of a nuclear waste repository, the future prospects for permanent disposal remain unclear."

Everyone can clamor on for nuclear while wind and solar continue to rapidly decline in cost, and manufacturing capacity for both continually increases. The hill for nuclear to climb gets higher every day.

I have a layman question if somebody could please answer. I have never in my entire life seen databases fail. But db failures and issues seem to be brought up all the time. Now I understand that part if this maybe the cost function associated with them. But I'm sure there's also something that I have no clue about. So my questions are:

1) what kind of problems do databases actually face.

2) what kind of scenarios create those problems.

3) how does a programmer go about testing them?

I presume you are being genuine, but you should know that your comment is almost indistinguishable from satire. More specifically (and hopefully more helpfully) it sounds like the comments made by Brian Wansink before his recent fall. Google for his story if you are unfamiliar.

Assuming the effects they found were actually legitimate (that is, the alleged "torture" of the data was statistically sound), how is this at all a bad thing?

Assuming that the effects are legitimate is exactly the problem. You are right, if we somehow know that the effects found are real and reproducible, then all is good. The problem is that we almost never know this. Presumably what you mean is "If the results are reproducible, what's the harm?". I'd agree with this, but the problem is how to know ahead of time that the results are going to be reproducible.

Shouldn't it be safe to assume that they could simply repeat the trial with a different stated objective and successfully yield the positive result?

If they did the statistics correctly (accounting for the multiple inferences, all assumptions about iid data met, no biased dropouts, everything else aboveboard) and got a really solid result, then yes, it's theoretically likely that the results would be reproducible. The problem is that they almost certainly didn't do the statistics correctly, and intentionally or not they probably violated a lot assumptions. In too many cases, even the main line conclusions can't be replicated. It's rarely "safe" to assume that an effect is real until it's actually been replicated, and almost never safe to make this assumption for result obtained by sifting the data after the fact looking for correlations.

I'm having a hard time seeing the problem with taking an exploratory approach and just testing placebo vs. some treatment and reporting whatever you find.

There are ways to do it this way, but it usually takes larger sample sizes than are available. It also requires "bespoke" statistics that are easy to get wrong. In practice, it's usually better to use the incidental "results" as idea generators for future experiments, rather than assuming that the findings are real and don't require further testing.
> Relative to not having the ability to reproduce at all in the future, or at an unknown diminished capacity.

That isn't what we're discussing. We're discussing opting to delay reproduction and using an imperfect means to do so. You're trying to conflate it with e.g. cancer victims or those who are losing their fertility, which wasn't your original proposition at all.

When there is no alternative it is a huge improvement, when you're opting into it for no great reason, you have to examine the costs more closely. You've stumbled into contrasting age based DNA damage with Cryopreservation's damage.

We overvalue the strong entropic and under estimate the weakly entropic forces. NASA has been trying to scale up nuclear heating as a means of propulsion but I’ve heard it’s now being used in fracking. On the other hand I’m psyched about the future of fission and fusion.
One of the main benefits of nuclear power is that you can take coal fired base load power plants offline which are a major producer of emissions. The need for large amounts of base energy consumption will never go away, it will increase as we add more manufacturing capability and to match this nuclear plants are the clear option to cheap, constant supplies of clean energy. This maintains a lot of infrastructure while essentially hot swapping power supply.
