You can also order non-food items on Postmates (e.g. stuff from Home Depot).

Also anecdotally, the probability of an order actually arriving and being correct seems to be higher on Postmates. Perhaps the drivers there are more motivated to do a good job.
That doesn't say what you think it does. Additionally, the Democrats had a super majority for two years under Obama and ended up passing a healthcare bill written entirely by insurance lobbyists. The ACA skyrocketed health insurance costs, by every objective measure. They had 2 years already. I don't see how the exact same elected officials won't squander another super majority (which will be hard to get).

In my opinion, a D house and R senate is likely -- which means no universal healthcare.
I believe the fallacy is believing that since some testing is good more must be better.

I've heard that on Postmates you can use the write-in functionality to order from a business that isn't on their platform at all (you order from a nearby business and in the write-in field tell the Postmate to go across the street, etc). I'm not sure if many of the other services provide a way to do that.

First; remember there are two "TikToks": The Chinese version which is mostly in Chinese and operates mostly in China and then the western version which we all know and love.

The first one you can be sure operates under Chinese law and shares data with the Chinese authorities.

The second; my bet is that ByteDance wants to sell it off probably through an IPO on an American exchange. That is why the have hired an American CEO. And that is why they make announcements similarly to Facebook and Google on Hong Kong.

What will happen in Hong Kong? Will all these American social medias be banned because they refuse to follow what is now Hong Kong law?

Essentially expanding the great firewall of China to include Hong Kong ... we will see but my guess is probably not.
You can get RTSP feeds off the cameras.
Everything in this article is correct except the conclusion that it's better not to write tests. Testing is an artform all its own. I find two tricks indispensable.

First I declare a "foo.src.js" file to hold a module's logic, and then a test file as "foo.js" and have the test file import the logic and then export whatever is to be public. Client code imports the test file and not the source file, so the tests sit in between the logic and the client code, as it were. No more balancing testability against encapsulation.

The second is indirection. I create a mockability decorator. Then have a function (I call it 'mock') which can be used to temporarily redefine any function declared mockable, and then switch back to the real thing when the current test is through. So I get:

const readFile = mockable(fs.promises.readFile)

...

mock(readFile)(async () => 'mock file contents')

Combining these approaches doesn't so much prevent rework on tests when code changes as it makes it much less trouble to implement tests for 98% of cases.
So what's going on with travelling wave reactors? There was a lof of hype around them a few years ago, and then nothing?

It's not just you, but personally, I've never been interested in getting rich. For me, HN is a replacement for slashdot, after every second comment there was racial slur copypasta. I'm here for the technical articles and wacky projects like this.

For myself, opportunities to hack on fun side-projects are rare but I cherish them. Geeking out brings me satisfaction and joy. I've put a couple of fun projects on github and every fork & star is a little hit of shameless gratification: unlike karma on these blasted social sites, it feels like I've done something tangible to bring a smile to somebody's face. Because I did! That's not an intangible, it's good for my mental health!
That’s not edgy enough for HN ;)

Seems like an overall well-intentioned founder story. Wondering if there are Luxonis people out there who can address the below?

Would like to give the benefit of the doubt here to the CEO and Intel, but being weary of Intel’s past “hacker friendly” blowharding and subsequent total abandonment of the hacker community with the Edison, I do wonder whether Intel is again playing the mafioso; the wording of this quote from the Luxonis CEO comes off, to me at least, as kissing the ring,

> “DepthAI, powered by Intel Movidius Myriad technology, is making it tractable.”

Also wonder about the nature of the open source software the article refers to,

> The Luxonis CEO said that the SoM works with a wealth of code that the company has open-sourced through an MIT license.

Is the software running on the Myriad X itself open source, or just the SDK interfacing with it from the host machine? If the former, pretty amazing they were able to get Intel to agree to this, as I imagine the chip details are under strict NDA. If the latter, it seems pretty disingenuous to refer to the SOM software as “open source,” at least not with a footnote that the most interesting part (the spatial depth calculation) is not, presuming that’s done on the Myriad X.

"So the final product is a multi-camera, rear-facing bike-light, which uses object detection and depth mapping to track the cars behind you - and know their x, y, and z position relative to you (and the x, y, and z of their edges, which is important).

What does it do with this information?

It's normally blinking/patterning like a normal bike light, and if it detects danger, it does one of two actions, and sometimes both:

1. Starts flashing an ultra-bright strobe - to try to get the driver's attention

2. Initiates haptic feedback - to let the person riding the bike that they're in danger

3. Honks a car horn. This is if all else fails, and only happens if you are in certain danger"

My initial concerns with DeVos were twofold: first, she had never spent a single day in an American public school and second, that the primary reason she was appointed was the millions of dollars she contributed to Trump’s campaign.

It seemed very unlikely that out of roughly 150 million eligible Americans, the very best choice was someone who had zero experience with the public school system.

After she began her work, the thing that I particularly disliked was her support of Indiana charter schools to both receive federal taxpayer funding while at the same time being allowed to ban a student for being gay (or their parents being gay).
This was my own father's experience. Not being able to drive for an entire year after his peers got their license was a major social handicap, especially in a more rural area. When I skipped a grade to get into an accelerated program, my dad deliberately held me back a year the following year to prevent the same from happening to me. It worked out ok because it was a tiny school district and the accelerated class was 30 kids across three grades under a single teacher.
Testing and documentation are both essential but too much of either becomes harmful.

Lack of purpose: social media app that is allegedly heavily spying on its global users in favor of CCP would not be useful in a territory where Chinese government already forcefully requires anyone to disclose user data to them.

External and internal optics: anything available in Hong Kong yet unavailable in China is liable to make Hong Kong appear separate of China.

Collective mindset: Western UGC, even if censored to a degree, carries values and notions that threaten CCP’s power and influence over given territory. (I wouldn’t be surprised if TikTok’s Chinese sibling is going to be heavily promoted in Hong Kong, if it isn’t already.)

I experienced long term psychological effects from lack of proper education pacing.

From the very beginning, I entered kindergarten as the only one in my class able to read. The teacher, doing her best, sent me off to read by myself in the corner as she taught the rest of the class. In the years where your brain is programmed to adapt itself to the environment it expects for the rest of life, I only ever had to do things which were to me trivially easy. There was this constant social distance and having to put on a sort of mask in order to interact with my "peers". At the same time everyone around me was always telling me how smart I was.

Everything was easy until it wasn't and my subconscious was simply unprepared to cope with not everything being trivial and socially making it very hard to actually be myself around people because of this very strongly built in assumption that nobody cares about what I think in conversation (amongst other things) so that I simply couldn't think of anything to say.

The struggle is real and never really has gone away.

It seems to me that someone with this philosophy has never tried to change or refactor a subsystem of a very complicated legacy project. Sure, sometimes your tests fail because they're poorly written and test implementation details, but other times they catch the fact that you didn't know about case X that had been discovered years ago and required a minor non-obvious tweak in the code to make work correctly.

“Took years to catch up” seems a loaded sentence. So yes maybe someone wouldn’t act like a 20 year old until they actually turn 20. But that is’t a great argument for keeping back their education for 5 years.
If academic acceleration was more widely accepted you would just have been starting at 15 with other 15 year olds and there would have been no social context pressuring you to act 5 years older just because you did well in school.
I don't need to get the full benefit to care about the difference. And in my experience there's a lot of screens closer than 10 feet to couches.

On mobile, 720p starts to get shoddy once your screen hits 5 inches across.

So while 4k is situational, and encoding quality is more important than the extra resolution most of the time, 1080 vs. 720 is pretty clear-cut; 1080 should be considered the minimum for most content.

The reason the other commentator thinks your post is bullshit because it doesn't address the clause in the order that requires F-1 students currently already in the country to leave if classes are online-only.

You need to be quite confident to do this as it can often result in car drivers honking, shouting or overtaking recklessly and nearly clipping you. Less experienced cyclists often feel much safer hugging the right side of the lane, even though as you mention this is much more dangerous, especially the risk of being doored (I learned that lesson the hard way). Depends on the city and cycling culture a bit but thats my experience.

I'm not sure what your point is here - your implementation will fail the parent's test?
a missing link is that one specialized tester in a team every 5-8 devs makes devs a lot happier, makes test more robust and makes the whole squad more productive especially reducing regression over time by a lot, especially on fields where the code has to run on multiple platform and devs only ever use one.

it amazes me we're doing the opposite of the best practices by piling everything unto the mythical full stack dev, while the rest of the world moves toward specialization

this focus on forcing devs on writing tests and learning to test better is highly inefficient for all parties involved, both in term of output quality and time commitment.

and the first thing that gets cut when under time pressure is, in fact, testing. and a dedicated tester is resistant to that.

the real thing is.. almost nobody want to pay top money for a specialist so nobody wants to specialize in the profession.

What to think about Ultra X Prime?
Much the same as men, a lady's body likewise contains testosterone however they are available at a low level. In any case, in a man's body, testosterone assumes a significant job and their sexual wants are absolutely subject to it. In this manner, with the assistance of Ultra X Prime, you can undoubtedly fix the issue of a slacking drive. This male upgrade supplement will expand your sexual desires and will ensure that you are not experiencing any of the issues that join a low sex drive.

Her actions and policies aren't well-publicized, but they're not good.

As a simple example: in 2017, DeVos and Trump proposed "cutting $1.2 billion for after-school programs that serve 1.6 million children, most of whom are poor, and $2.1 billion for teacher training and class-size reduction" [1]. These cuts also affected efforts such as mentoring, recruitment, and retention [2].

In 2018, she proposed regulations that "require full hearings, cross examination of sexual assault victims, and raise the standard of evidence to hold a student accused of sexual assault accountable" [3], which experts have said "would allow schools and the Department of Education’s Office of Civil Rights to ignore much of the sexual harassment that occurs in schools" [3].

I don't even know how to summarize this whole mess, so I'm just going to use the subtitle of the article: "The administration wants to keep schools safe by ditching rules meant to prevent racial bias in school discipline" [4].

More recently, she "illegally delayed an Obama-era rule that required states to address racial disparities in special education programs" [5].

Yes, these are exactly the topics the book addresses. A lot of it focuses explicitly on the difference in results between charter and non-charter schools in the same building, with the same demographics and student pool. If you're thinking of a "what about x," it is probably considered.

Many of those questions about past situations are illuminating for interviewers about the kind of manager you are / how you think about enabling teams, though they can certainly seem odd if you are not sure what they are trying to evaluate. (Often that is intentional, as it’s a lot easier to, say, pretend to have empathy if you know that’s exactly what they’re looking for.)
