Angular 1.x has this dreadful thing called digest cycle. Long and short of it, the rendering performance degrades proportionally with the number of things Angular has to watch for changes.

Some people retrofitted busier parts of their apps with react views to work around that. There are even a frw angular directives for that out there.
This is the reason for measurements of intermodulation distortion and THD+N by frequency. A proper evaluation of, say, a power amplifier will look at a dozen, maybe a couple dozen different measurements; taken all together, these provide a reasonably complete picture of how the amp performs.

But - from an engineering perspective, music can in fact be decomposed into a series of sine waves - and effectively all digitally recorded music goes through this process as part of a/d conversion (sort of; it's complicated) or FFT-based digital equalization.

I've also been doing interviews for a few years at three different companies, and I've encountered it. It depends heavily on the quality of the recruiter. Good recruiters will attempt to filter out complete duds, bad recruiters will pack a clown car full of "rockstar candidates" that just wasted my time. There was one particularly bad instance where a guy with 10 years of experience and a masters degree got stuck for an hour trying to write a for loop. With unfettered access to Google.
Just so counterintuitive that it's cheaper to send something halfway around the world than 5-20 miles away.
>To me it looks like there are many people either offended by or incapable of dealing with other people making different choices. The whole debate seems to be a way to force others into coercion and the actual limit is chosen to coerce as many people as possible.

This observation applies to a hell of a lot of things.
THD is a measure of non-linearity, which adds harmonics not present in the original signal. Yes, the standard tests use sine waves, but the results are applicable to other signals. Just because most people don't listen to sine waves for fun doesn't mean it's a valid measurement.

On the other hand, the highest THD in a sound reproduction system comes from the physical transducers. Worrying about the THD of an amplifier makes little sense when the speakers provide an order of magnitude more distortion.

I think a lot of the counter-intuitive effects in traffic engineering are due to traffic arbitrage. If you make a path much better more people will take it until it's as bad as all the alternate routes.

Think of it this way: the “cost” to realize a net profit of $450 is a tax expense of $450. What if you could reinvest that full $900 so that next year your revenue and income are higher? High-growth businesses will optimize for reinvesting because they expect the Return on investment to be higher than the return on realized profit going forward.

This is what Amazon has done for years - it generates a monstrous amount of cash (free cash flow) from retail and funnels it back into expanding current businesses and creating new ones such as AWS. AWS now generates its own surplus, so the cycle continues.

Edit to clarify: Amazon in the past has shown a relatively small net income vs large top line revenue because most cash is reinvested. It’s been a few years since I paid attention to their financials so things may be different now.
is there any evidence that traffic speeds have actually reduced due to the speed limit change? the vision zero project includes a whole bunch of stuff, including redesigning dangerous intersections, which the decline in pedestrian deaths could be attributed to.
In terms of a political solution, why aren't there some kind of subsidies to these bottling companies for using another material that is more recyclable?
> From what I understand, basically a user-space program that wraps your container and intercepts all system calls. You can then allow/deny/re-wire them (based on a config).

gVisor actually intercepts and implements the system calls in the user-space kernel. Two specific goals of gVisor are that (1) system calls are never simply allowed and passed through to the host kernel, and (2) you don't need to write a policy configuration for your application; just put your application inside gVisor and go. These are significant differences over simply using something like seccomp on its own (what the architecture guide calls "Rule-based execution").

Playing "Cities: Skylines" on PC and growing your small village into a metropolis will teach you a lot of things about traffic. More options for cars are usually not good for traffic flow.

The drivers in that game don't crash, and otherwise their behavior is greatly simplified, but each vehicle in that game has a start and a destination, and you can follow delivery trucks as they deliver packages and then go back to the Depot to pick up more. It's very fascinating, and may offer us some small window into the kinds of things that traffic engineers deal with without trying to find or write traffic simulation software.

And, of course, there are mods to give the player (the Mayor) greater control over lane usage and where stop signs and traffic lights are placed and how they operate. Doing things wrong will quickly result in localized gridlock.

Some people think one year is one orbit around the sun, and not exactly 365 days. Leap years help to keep that reality.

Some people think that a day is one revolution of Earth's axis, and not exactly 86400 seconds. Leap seconds help to keep that reality.

The fact that axial rotation is less predictable than orbital paths is a quirk of nature.
I don't think I understand your point. I was talking about how algorithms interviews map badly to the skills required by the job description. That's only tangentially related to whether you'll have to do things outside the strict job description.
Perhaps a stupid question: Why isn't there a time standard that is monotonic and defined simply in terms of seconds, without attempting to match the movement of the earth (no leap seconds, no negative seconds, no daylight savings, no complicated calendar politics)?

If such standard existed, wouldn't it be the best to use for programming, with "simple" conversions to/from the all the other standards?

Basically, I want a monotonic clock that starts at an arbitrary point (I would suggest Isaac Newton's birthday), is able to go all the way back to the big bang, and forward until the heat death of the universe, with millisecond or better precision.
I appreciated your original comment for the reasons you listed in this one. +1
I don't believe you can distinguish the two, especially when someone takes a deliberate and motivated action which they can fully expect to land them in prison. (See: organized crime.)
In Berlin (I don't know if it's different in other parts of Germany) and in Poland the default speed limit in cities is 50kph (~30mph). In Berlin most drivers match speed limits. In Poland most drivers ride at 70kph (~45mph) in cities. But Berlin drivers will drive above speed limits when there is a short section with construction, when nothing apparent is happening on it. Maybe they will take the feet out of gas. But most are not riding with 30kph (~20mph) speed limit in this case.

Reasons for the discrepancy between Berlin and Poland is in mentality for sure. But I think that more roads are really set for the speed limit in Berlin than in Polish cities I know. So you can drive faster, but you will just be first on the red light. As they say: slow is smooth and smooth is fast.

It certainly helps that the Autobahn network have nice stretches without speed limits. I feel that car in Berlin is really just to go to the highway and not to move through the city itself. The limits just picture the priority of public transport and bicycles in city planning.

What's funny is that I like to drive more in Berlin than in Poland. It's smoother and drivers seem more used to interruptions. Even though I still drive more in Poland and don't really need a car in Berlin. However parking is pain in whichever country I am.
This is actually a really big problem called invoice fraud. Many companies struggle in setting up some workable system to prevent it.

The problem usually is that someone at the accounts payable department (sometimes in a different building or country) must pay all the hundreds or thousands of incoming invoices. Having a robust system in place for them to check if the product/service is actually delivered for the price agreed upon (or even delivered at all) is hard.
> Yeah, and it will take a millennium for Earth rotation to shift enough for people to notice it. On the other hand, you'd have no problem with summer/winter time I presume?

No, I don't, as they are just views on a monotonically increasing time scale named UTC that keeps up with Earth's rotation, so that every single thing from climate diagrams to everything else humanity is syncing on keeps working and being comparable.

> We can still use timezones to fix the shift.

Or, we could not do that. Everyone is free to use TAI inside their own projects as they see fit if they have the needs for strictly monotonically increasing time. I would argue that leap second smearing has way less artifacts in practice than bolting time zones onto a shifting UTC time.
Back in the 90's, I got a buddy hired at my work, and typically all co-workers come through a contracting agency. Work hired him as a direct contractor without the agency BUT at agency rates. He did his 90 day contractor probation period and then hired directly.

After he left the company years later, he told us the story of the 175 hourly rate they gave him for 3 months, instead of 25 for a junior admin.

Good times.
A few years ago I went to Twitter to see what my friends were doing, and to talk to them. There wasn’t much yelling.

Then Gamergate happened and people started yelling about it, and then that grew into the alt-right and that got more yelling, and then Trump got elected and it’s just been so much yelling.

And now here I am mostly on Mastodon, where there’s next to no celebrities, brands, or other things to yell at, and it’s pretty nice.

Regarding your last link - lower speeds and lower speed limits are not the same.

Also, your claim that it’s lower speed limits that reduced deaths seems not entirely honest - the articles say that there were more things that changed besides speed limits.
He called it sir hat somewhere in the show hn thread so I've been calling it that too.
Sure, it's possible that pedestrian deaths can be reduced by lower speed limits.

But in busier roadways, what I've observed is that slow drivers tend to be biggest danger now - and that is naturally because slow drivers tend to also be distracted drivers (by cellphones or otherwise). Naturally, such distraction is a bigger and bigger phenomena and dealing with them by making it clearer how they ought to drive seem OK.

The recommendations look very good, and don't particularly match the Yahoo article.

1. They recommend IEEE 1789 as a flicker standard for Europe, which is fantastic, as it covers lower levels of stroboscopic flicker that other standards have missed. (e.g., typical 120Hz flicker from direct-wire TLEDs)

2. They re-state the "acute" hazard from extremely bright LEDs, while urging some caution on "chronic exposure" to lower light levels. Suggest that some automotive lights could be a problem since they have high luminance. Urge more research on progression of macular degeneration and chronic exposure. The question about acute levels refers to a paper by Hunter [2012]. Nobody is saying that screens or residential lights pose a new problem.

3. Circadian recommendations are solid - more light during the day, and reduce light around 480nm at night. Pregnant women and children may have lower thresholds.

4. Say most ophthalmic lenses filtering blue light don't do very much, and specialized ones (you'd say very orange or red) are required for circadian effects.
I received an email to my free Mailchimp account explaining this change, which included this:

> As a current user of our Forever Free plan, you'll now be in the new Free plan as long as your audience size is 2,000 contacts or less. The new pricing structure is based upon the total number of contacts you can market to, which now includes unsubscribes and customers who have simply not opted-in yet. You can check your Mailchimp account to see how many contacts are in your total audience. And keep in mind, you can always archive contacts you aren't using. On June 15, 2019, the pricing change will go into effect if you have more than 2,000 contacts.

So it sounds like it very much does change pricing on June 15th, at the least meaning previously Free users will now have to pay, unless they go in and manually archive unsubscribed emails.
Online sales are only projected to account for about 12% of retail in 2020, and retail is only a small percentage of the overall economy.

>If it allows more people to buy iPhones then most of the jobs created by that is made in China

Only a small part of the value of an iPhone is captured by China. Not much of it goes to the local economy either, but luxury electronics are also a small fraction of the economy.

Dining out, groceries, retail, housing, transportation, entertainment, travel, child care, home repair, cell phone repair, medical care etc... the local economy captures a large percentage of all of those.
They may have a tax rebate which requires them to "invest" $x each year and failure to do so will result in penalties, perhaps nullifying the agreement and requirement to reimburse previous rebates.

So the company hires a few contractors to help get them as close to $x as possible, but they don't really have any work for them to do.

> This is the history of a successful charlatan.

For two summers in college, I worked at a Home Theater company. They did custom home theaters, distributed audio, and a ton of mixed AV stuff. Needless to say, the majority of our clients were very rich and most of the theaters we installed were in the 300K-500K range.

The funny part was the owner constantly talking about how much better a $25K pair of speakers sounded than a $15K pair of speakers. I've heard a lot of great speakers, but was never good enough to tell the difference at that level. I finally asked the owner's son why he would push something that didn't seem to be a big upgrade from 15-25K for these speakers.

The answer was simple. His margins on the more expensive ones were better. His rich clients never questioned his expertise, it was pretty eye opening. The next summer, I finally realized everything he pitched his clients on were always about maximizing his own profit, not necessarily designing the perfect bespoke theater for his clients.
Thanks for the link! As for the pun, no, it was a happy accident. I'm not that clever :P
> Glass houses are a thermal crime.

I don't think this is true. Some of the most energy efficient houses are passive solar houses that use large glass surfaces for heating that are covered using shades in the heat, but also use high thermal mass materials for heat/cold storage.

From an aesthetics perspective, many people like natural light, I wouldn't want to live in the houses you provided as examples for that reason.
That's a bit different. You're effectively getting "taxed" 100% on whatever is left over so you might as well spend the money on anything that has non-zero value to you.

But if you, say, only lost 30% or 50% of the balance, it's not immediately obvious if you should spend the balance or not.

OT but this is such a weird aspect of FSAs. I can carry some amount over with my plan which makes things a lot easier.
OP here. There are some good guides [0] about using Python's asyncio module (and libraries built on top of it) but I hadn't seen a comparison of it to threading which is what I prefer for client-side coding. The key difference is that using the async module requires modifying every function in the call stack, while threading can be cleanly wrapped around existing code. So although threading has more of a memory footprint and feels less Pythonic, it's a much better option when working with third-party libraries.

"It may make parents feel better if the speed limit on their street is 25 mph instead of 35 mph, but that sign won’t make people drive any slower"

Just changing the sign doesn't make people drive slower, but if you actually enforced those speed limits people would slow down and pedestrians would stop dying. Traffic calming may be a cheaper way of slowing people down than enforcement.
> That's irrelevant. When talking about language consistency, we should also be including the language's standard library.

As you said, PHP was merely an interface to (many already existing) modules written in C. When people complain about mysql_real_escape_string() in PHP they don't realize that that is the actual name of the function in the MySQL C API. Same with the image functions (imagemagik). And so on. Some are named directly after the corresponding C standard library function.

This was actually part of the huge success of PHP -- it made available, for the web developer, a huge library of existing open source technology. This did not exist, in a scripting language, before PHP. The open source community wasn't as large.

But PHP does have high-level abstractions and, like with other languages, you would also use a framework that has high-level abstractions.

If you compare PHP to JavaScript, PHP's standard library is far superior. But it's a ridiculous comparison there as well.

> The problem is that PHP wasn't designed as language-first but a tool to make web development more accessible.

Yes, but all the ways that PHP as-a-language were less than ideal most of those have been solved now. So unless you're complaining about the standard library, there isn't much left.

> Nowadays, the deployment issue has long been solved. No one should choose PHP if they have a choice as there numerous languages better designed, more performant, and more generalized than to just web dev.

Nowadays there really just isn't that much difference in design or performance between PHP and the majority of languages you would suggest.

I'll add in; astronomers like to be able to find objects in the sky using calculations based on time. UTC (actually TT, which underlies UTC) is good for that.

Spend a little time on the various wiki pages for time standards, and think about why those things exist.

You can see the Vision Zero data here: http://www.nycvzv.info/

I don't think your interpretation about speed limits is correct compared to other factors mentioned in the nytimes article:

> more stringent enforcement of moving violations, revamping hundreds of street corners to slow down turning cars and rejiggering crossing signals to give pedestrians a head start.

For one, traffic in NYC just doesn't move that fast, especially on the streets where most of the accidents happened. It's not really appropriate to extrapolate NYC data to the rest of the United States unless you focus only on urban centers.

Second, almost all of the fatalities seem to happen around intersections. I'd expect to see more jay walking deaths in the years before the speed limit change if your interpretation was correct.
I'm not sure if it's identical in the Bluetooth world but the USB keys do present as a HID keyboard because the one-time pad & TOTP functionality require it to emit a string of random characters and there's no other generic way to do that.
The data in your links is inconclusive. It is improbable that the 25mph speed limit, in effect for only 2 months, accounts for the drop in fatalities from 2013-2014. There were lots of other Vision Zero things happening in 2014 that likely had a bigger effect. 2015 was the first full year with the speed limit, and it looks like no real impact from 2014.

2014 (2 months of 25mph) : 140 pedestrian fatalities

2015 139 pedestrian fatalities

2016: 148 pedestrian fatalities
They announced a lot of things, and this was just one change in a slew of new product expansions. Seemed reasonable to me.
The last ten years' experience with renewables has shown that local-scale generation is underwhelming and large-scale deployments are the way to go.

With the exponential recent declines in production cost, most of the cost of solar is now in deployment, not manufacturing the cells. This has made huge desert installations much cheaper per watt than rooftop -- as a result, large-scale installations is where almost all the growth is coming from.

As for wind power, efficiency increases superlinearly with blade length. As a result of this, and improving material science and production/deployment tech, turbines have been getting enormous (Eiffel-tower-sized or more) and no longer fit outside of dedicated wind farms.

As for nation-wide grids, they're are a central part of the solution to solar/wind intermittency (because weather patterns average out over long distances).
