I lived in an apartment two floors above a pool and barbecue area for a year. I regularly had severe air quality issues that did not affect the floors below me. I could watch the smoke from the barbecue grills rise up to my level, then travel horizontally across and into my poorly sealed windows due to persistent local air currents.

I moved to another apartment building for the two years after that, and continued to have measurable AQ issues because the dryer, bathroom, and kitchen vents were flowing in reverse due to a poor building ventilation design that used a single central vent shaft and didn't adequately account for wind or the height of the building. I was on a side and floor of the building that had negative relative pressure much of the time.

Air isn't a perfectly homogenized uniform fluid -- there are very localized effects, and because it's often invisible, those local effects are often dismissed.

IMO the only sane and responsible way to develop apartments in a challenging environment (by a highway, by a fire or bbq environment, in an area where weed is legal, or on a toxic site) is for every single unit to have its own air handling system to maintain air quality and positive pressure in that individual unit.
SC:2013 had a lot worse problems as well with how it chose to do agents.

- In C:S agents are mostly used to allocate work/home slots, and to depict traffic. SC used agents for everything, including simulating how individual poops would reach a sewer outlet, or how power or water reach homes. So they used computationally expensive algorithms to simulate things that no one cared about actually seeing like that.

- Because of the very heavy computation, to make the load workable they limited city size to 2km by 2 km, or 4 sq km. To put this in perspective, the land area of Manhattan is 59 sq km. SC:2013's scale would be as if the city you built would only get to be built as big as Central Park (3.5 sq km). This is fine if you want to simulate a medieval town, maybe, but probably not a modern city with trains and highways and stadiums and things that take up a lot of space.

This is what I was thinking. As a creative output device My brain thinks way ahead while I’m typing the current code. This tech will actually slowdown the process with respect to output
. What this will thrive at is, giving input to the brain about data by brain generating just enough query. So ultimately future super human will be the guys who can generate precise query much faster.

Tesla would kill you half the time making this unprotected left turn. Waymo can make unprotected left turns and have never killed or injured anyone or even bent metal in this situation. :P It's not a particularly challenging left turn.

And the goal is to kill you less than .0001% of the time making left turns.

Yes, Waymo tries to avoid them in route planning, but it still takes them if necessary.
Right. If the hostname requested by the worker is a host that is itself protected by Cloudflare, then all of that host's usual security settings apply. Nothing is bypassed.

The author of the blog post seems to have been confused by the fact that different behavior happens if the target host is on Cloudflare vs. not on Cloudflare.
I didn't...but not on purpose. I was so out of it when I came to, I didn't even put two and two together. I just said I didn't know anyone named Charlotte.

It wasn't until the car ride home that someone asked me again that I was like...oh, no, Charlotte the city not the person.
Nobody should have to choose between living a healthy life and feeding their family.
IMO, the bigger problem, which nobody talks about, is that if we have brain-computer interfaces, it will be trivial to use them to control our emotions. Once that happens, it seems to me we'll basically stop being human. People are going to want to feel whatever emotion is convenient in that moment.

Don't enjoy your terrible dead-end job? Now you do. Don't enjoy your abusive relationship? Now you do. Don't feel comfortable with societal issues at large? Now you do. Empathy gets in the way of doing your job? No problem.
It's not just simple content sites.

The other day, I placed an online order for curbside pickup (with a national brick-and-mortar chain). When the time came, I drove up to their curb. But I couldn't access their "I'm at the curb, bring out my stuff" page. It just kept loading and loading. I had to go into the store to get my order.

When I got back to my PC, I discovered a massive webpack bundle on that page, along with an absurd level of tracking software. The page had transferred 50MB before I could even use it.

They knew their curbside page would be used exclusively by people on their phones, in their cars. They knew some of those people would pull up to stores with poor cell reception. That page should've been as light as possible. The page was ultimately just a simple form, so it should've been possible.
Somehow there is a world of difference in when one moves from Henry James to Hemingway.

It is as if James violates every maxim of how to write simply and clearly and succinctly, but ultimately his writing has aura of ambiguity which enriches it rather than diminishes it. He will go paragraphs and pages even, one has to mentally unwind a lot of it, like an intricate puzzle, to grasp the tiniest specks, bits of knowledge about the story, about the plot. And the thing is he doesn't do much description, all the details are abstracted but the seeming convoluted manner, and subtle hints deducted from indirection, it does create a captivating experience.
As a result of this HN post, 158 people visited the blog post I linked to, and only 112 people visited the Medium story. This is despite the fact that the blog link is buried in a child post, and only appeared later.

Buy here pay here auto lots are essentially predatory lenders using the cars as tokens. It's all about the loan not the car. They thrive on selling the same car over and over and will repossess at the drop of a hat. Two days late on your payment? Expect that car to be towed any minute. Even if the desperate customer manages to pay off the loan the lot makes credit card type interest on the transaction.
My honest take is that the frontend development stack focuses almost entirely on the developer experience (mostly oriented towards shiny things), and the user experience is only a secondary effect of that.

That the developer experience also doesn't work is just an effect of the real-world, where people will end up using stuff outside of the small designated bucket of things that somebody attempts to keep compatible with each other.
If anything, the argument to get brain interfaces implanted would be that it’s cruel to children not to implant them.

It’d be like withholding a vaccine against a genetic flaw, when the vaccine is cheap and sitting on the shelf ready to use.
We're talking about a situation where an attacker would create the service disruption by enabling Host header checks on an origin server that the attacker doesn't own. So a warning wouldn't help because that warning would be displayed to the attacker.

The logic is tricky, but in the end origin server ownership verification is what's required to safely support Host header checks.

Ask HN: How do you sell SaaS software to enterprise businesses?
This article feels like an effort to explain away, via “normalizing”, an understandable yet often unacceptable level of apathy rationalized by fear.

Life is messy, and most people don’t want to get involved in problems especially when the actors seem homeless or maybe feed into racial stereotypes. It can be a mix of feeling ineffective, distrust of what one is observing, a fear of physical consequence, and of publicity. These are all rational if not always correct.

We all feel it, and all of us fall victim to it sometimes - the brain quickly rationalizes why we shouldn’t intervene.

That’s kind of where the article stops, but I think it needs to go further in holding up the virtue of engaging to help others.

There is a switch that one needs to overcome, and it’s something you train your mind to do, which is to run towards problems, not away from them. When you do it once - like are able to “see” your brain giving you shitty instinctive advice, overcome it, and intervene to successfully help, you grok the dynamic and are more prepared for dealing with it in the future.

It’s a rewarding cycle, even if you get no credit (often best scenario), and can drive you to improve your own skills (like learn CPR, etc). You never know when you’ll be in such a situation but I think it’s important to prepare your mind for it, understand your own values and establish principles ahead of time for when it’s okay to get messy. But I think all of us, as responsible members of society, tend to owe some level of action depending on our capabilities. There are plenty of situations where it’s ill-advised to intervene, but more often than not freezing up is the wrong reaction and we need to encourage courage.
Sure, though this is trivial. Every artifact crated by people shows ideology. Chairs show the ideology of conforming space to human physiology.
yeah no. FB is not a requirement to participate in life. never was, never will be.

Slide 11: Don't bypass security settings for hackday.

Well then, don't have hackdays. Or have change processes so streamlined and automated that hackdays don't have to exist.

The whole point of hackdays is to get quick POCs developed in record time, bypassing the normal rigors of planning, backlogging, storypointing, lab/dev/test/prod and just get something working.

And in my experience, it's a service or feature that the security side of the CICD pipeline isn't prepped for. So yeah, you have to bypass things sometimes.

Excel doesn't support CSV files. Anyone who believes that has never used Excel. [0] You're supposed to use spreadsheets as is. Programs that have excel export features should always directly export xlsx files.

[0] The only thing you can safely do with CSV files is to interpret every value as text cell. CSV files always require out of band negotiation on everything, including delimiters, quotation, escape characters, the data type of each column.
As a 1:1 exact problem, no of course. As an analog to challenges, sure.

There is also the “who is more important” problem? A self-interst version of the trolly problem. When asked this, a Mercedes executive explained that the driver was the most important person to the vehicle. So given the option of hit this biker or swerve into oncoming traffic, they would chose the biker. So, somewhere in software there is a decision to always protect the driver, interesting problem that we have no good answer for. Back to my point though, I’m skeptical we’re even close to having all the data to make the decision properly.
From the moment I read "full broadband fidelity," I began looking at this press release as a product of dark-pattern science communications rather than an announcement of scientific progress. The news is that the connection is wireless and high-bandwidth. Low-bandwidth wireless communications have already succeeded elsewhere. Innovation could have occurred regarding the interface device in the brain, the broadcast chip in that device, the physical link link layer, the protocol layers above that, the external receiver, et cetera, but there are no details we can clean except that the connection is 'virtually' as good as a physically wired connection. Wherever details are missing, we can assume neither that they were overlooked by the writer, nor that they were deliberately left out. We can assume, however, that they did not contain any information which furthered the author's purpose.
/dev/random is super slow and even /dev/urandom is surprisingly slow. If you care about performance, something like round reduced AES or ChaCha would be a decent choice.

> I ended up caulking the entire apartment with clear caulk and sealing any air gaps. Because the hi-rise was pressurized like most hi-rises, I concluded somehow this was drawing up smells from grease traps etc.

I would be cautious of taking actions like these as it can have some pretty bad knock on effects. I'm on the board of my condo corporation for a high rise in Canada and we have seen topics like this come up from time to time.

To help control odour between units, the air handling system in our building is designed to draw air into the hallways, from the hallways to the units, to outside. The idea of routing airflow like this is to try and prevent smell transfer between units, but the airflow also has a purpose to help control moisture buildup, which IIRC gets worse if there is no airflow, and can lead to mold. So we discourage blocking the airflow from the way the building was designed, and property management has advised us in other buildings this had been observed to lead to severe moisture problems.

And we have had issue pop up with trash smell and the like. Where that's happened to us is two causes, there is a sort of air damper on the garbage chute, and it's gotten jammed on us IIRC. The other is our garbage room opens to take the bins out, and if the doors are left open for an extended period and the wind hits the building right it can draw air through the garbage room and through the chute. This can also occur when folks leave their trash blocking the chute door open allowing more air to flow between the chute and hallways.

Stuff like that can be hard to figure out, because if the garbage room is left open every day, it doesn't always happen due to the wind or possibly other factors.

The third one we get sometimes is smoking smells, which is usually caused by a smoker not wanting to use their balcony in winter, so instead they go into the stairwells. We traced one of those across more than 20 floors once. It can be difficult to trace those ones, so it comes with a lot of sending broadcast messages and work to trace down.

I get not all property managers are super helpful, but if they get a few reports from different individuals and can link it to some action like having the garbage room open can hopefully have them solve the real problem.

Are Humans Prepared to Detect, Fear, and Avoid Snakes? The Mismatch in Evidence
Generally the tanks are fiberglass. I don't know why they leak. From reading site reports, my impression is these leaks are usually detected by the tax authorities, who can see that the reported sales of fuel don't add up to the reported deliveries of fuel. See page 40 of this report for an idea of what an underground fuel tank looks like.

Basically, any scientifically/1st principles viable technology that might save us from doing extensive desperation geo-engineering deserves some investment, from a cost/benefit point of view. Otherwise, we might learn that we coined the name "Antropocene" too early.

There is no viable future scenario in which mankind's energy usage decreases. It's a pipe dream, and ultimately a dangerous one.

Agreed. There would need to be crushing totalitarian rule over everyone on Earth to prevent progress, and that wouldn't be stable long term. Otherwise, competition by competing powers will inevitably result in a Kardashev 2 civilization. Here's why:

Space solar power and fusion power are a couple of serious tech/economic inflection points. Once humanity's technology and our self-organization reach that level of capability, we are literally within striking distance of threatening any star system in our galaxy with huge destructive energies. We only need one of the two for this to be the case. Fusion is unnecessary at this point. If someone can establish large-scale industry on the Moon and the asteroids, solar power will be every bit as good as fusion in many regards. (At large enough scales, solar power is fusion power, basically.)

Modern geopolitics are dominated by the logistics of energy transport and production. It has been this way since before World War II. The logistics of fueling factories, ships, then tanks and airplanes has absolutely dominated strategic thinking since even before that time. The lengths to which the allies went to provide the fuel to run the invasion of Europe were absolute feats of engineering, planning, and intelligence/disinformation. So just think ahead a bit: what if, instead of having to fuel your military, you could instead beam power to outposts, which would use that power to synthesize fuel? The side that can do that would have huge logistical advantages, which would also be strategic advantages. (There's a compelling reason why submarines and aircraft carriers are nuclear powered.)

Going further, once we are at the level of space industry at scale, the Earth becomes just one location in a much larger context, whose available energy dwarfs the available energy on Earth by many orders of magnitude. At those levels of available energy, we could build things like Shkadov thrusters and Nicoll-Dyson beams. At that point, we'd have the hypothetical ability to move stars and build devices that could fry the biospheres off of planets in the bulk of our own galaxy.

The depiction of medieval folks wearing drab and dirty and torn clothes in black, browns, and and grays is THE biggest peeve I have with costume design in ‘historical’ movies and tv shows. The absolute worst offenders in recent memory being Vikings and The Last Kingdom, but there are a plethora of others. Not to mention the biker-gear-leather-fetish as armor look they all seem to go for.
>A lot of tools operate on CSV files.

The mistake was to believe that Excel can operate on CSV files. It doesn't support them in any meaningful way. It supports them in a "I can sort of pretend that I support CSV files" way.
In the past, people used their own manure and that of animals to fertilize fields. Manure contains lots of phosphorus as animals actually absorb only a small percentage from nutrition.

Urbanization broke this cycle. Sewer systems got established and the phosphorus doesn't end up on the fields anymore. It eventually reaches the rivers and seas and passes into the sediment. What a waste (pun intended). Instead, people started to mine graveyards (for bones) and guano on remote pacific islands...

Edit: Urine might work even better because reprocessing it is way simpler than dealing with manure. The nitrate and sodium levels have to be adjusted. Also, excreted pharmaceuticals have to be neutralized. Meanwhile, with manure one has to deal with pathogens, eggs of parasitic worms and a host of other ingredients, which might be difficult to predict in urban settings.
