You're very likely correct. The Lichess dataset that we have used contains almost all live games played on the site. As fast time controls seem to be more popular on Lichess generally, and take less time to play, we do see a lot more of these in the data. If you'd like to filter the dataset to different time controls or skill levels, you can click the graph button at the top of the page, then click dataset from the drop-down.

Doctors and techies are clashing at digital health companies
In Vancouver there is no such things as peripheral vision, but that is not due to mobile phone use. Indicators are also optional. I am impressed how there is not a crash every second. When you drive here with a bike you basically know that any car will just cut your bike-lane at their convenience and turn right at a traffic lite, right into your path...
Because then the owner denies driving it. Now, in some states they handle this sensibly, and the driver has to get the "driver" to own up or they are responsible. In other states, it is on the state to find the driver.

Ad networks that push adware or malware that facilitate click fraud. I would guess that anywhere from 2 to 3 billion dollars spent on Internet advertising each year is ending up in the hands of corrupt ad tech vendors.
Many of the comments are about the event as a whole, but I'd like to commend the author for the day 1 puzzle, which I think is very cleverly written. Many people (including myself) use these as an opportunity to try out learning a new language, and the first puzzle does a good job of making sure you know enough basic operations for some of the puzzles coming up. The puzzle itself wasn't very difficult, you could do it by hand if you really wanted to, but it required you to know how to read and parse lines in a file, handle compound data structures, iterate through, and perform basic operations (floor, casting strings to ints, etc). I thought it was really well done, and creates the basic knowledge for the puzzles ahead.
The point of the article seems to be to warn people that they are not physically capable of doing these things and to explain the human toll of a job like this.

Why so sensitive to Amazon?
It shouldn't be this way. The owner should be responsible, and it is up to them to find the driver.
> Funny how this all happened right when the American public would be distracted

The vast majority of the American public wouldn't care about this no matter when it happened.
Example: PACKAGE_native_append += "something". "append" is a keyword, but the "native" is just a separate list of native packages, yet both are appended to a variable name separating it by underscores. They use the same "syntax". If my memory serves me correctly, if not in this example "+=" is required sometimes after "append", even if they seem redundant. Someone politely explains you why this works as it does, it makes sense, yet you wonder why you need to hit a gotcha when all you are doing is something as simple as adding an item to a list (as a space separated string).

And then the metadata is also funny, e.g. do_patch[depends] = "whatever:do_populate...". Variables are not just variables, they can contain metadata, sometimes important.

It feels like there are usage patterns, good practices and something more beautiful wanting to get out, but this is a domain where making a better build tool would break tons of recipes, so it feels like everytime they got a problem they added a quickfix and got forward without looking back.

The steep learning curve most of the time is unneeded, you are frenquently doing trivial to simple taks and hit one problem that gets you blocked for a while for things that you are easily able to do outside Yocto.

It is a shame that the good work they do is spoiled by the horrible "interface".
Kun misquoted my review, stating "As the Amazon reviewer 'SCB' put it, 'the book feels more like a refresher than an introduction.' User 'zach' concurred, calling it 'not a kind introduction'..." In fact, I am not qualified to describe the book as a refresher, because I have no background to be refreshed.

Moving on, it's disappointing that Kun didn't see any value in improving his product based on common feedback. It seems like negative reviews would be an opportunity for the author to better understand the audience he marketed his book toward.

At the same time, it's disorienting to see a real person acknowledge one of my reviews. I'm sure if I knew Kun in person I would be far more appreciative and impressed with his dedication and work than I allowed myself to be as a paying customer. I want to thank him for taking the high road and not lashing out at me for the unproductive snark that peppered my review.
Total revenue from speed and red light cameras in NSW during the last financial year was $65 million: https://www.revenue.nsw.gov.au/help-centre/resources-library...

Total revenue for the NSW government in that year was $81 billion, with a budget surplus of $800 million: https://www.budget.nsw.gov.au/sites/default/files/budget-201...

Traffic cameras generate some revenue of course, but let’s be realistic – you could scrap them entirely and not even get 10% of the way towards a budget deficit.
Thanks for your feedback! Great to hear from people that are using LibrePCB :) I agree with most of these things.

Note: I think there was no DRC available in the board editor before 0.1.3, only an ERC which reported things like unplaced components. In 0.1.3 you have an actual DRC that checks things like copper clearance, minimum drill diameter, etc.

You miss why folks pick AWS I think.

When you say get a filer with 500TB that can do 10GiBy/s as a developer I might hear this as the reality.

Talk to infra group -> who will sit with a bunch of sales people and go round and round then get some quotes, then go back and forth with dev group trying to really spec out what is needed, then get finance / accounting approvals, more questions and answers, then put the order in, then have sales people apologize for this and that delay, then get filer onsite, the a big todo to install, then find the gigabit Ethernet can't actually push 10GiBy/s, then have to find add-in cards for all the servers and do a big network redo to get some kind of speed to the actual servers. Then after developers play with this a bit they decide to go a different route and the dance starts again.

Contrast with this AWS. I can try out my flow with a few clicks on console.

Security is painful though - no question.
Would anyone knowledgeable care to explaine why GaN based charges are more efficient than Silicon based ones ?
Hi, Marc from Cliqz. This one haunts us (in HN and also in my dreams). Let's first get one thing clear: It was a terrible blog post. Second: The 1% who had Cliqz installed were actually safer than the ones without. Why? If you use a (most) browsers every keystroke in the URL bar gets send to Google. This is how autosuggest works. This was and is the case with Firefox also. Cliqz in the functionally implemented in Firefox was not that different. Except - it comes with privacy by design: We actually proxied those requests to not get the IP, we take special measures to not collect private data in the first place. And all this was tested and scrutinized a lot before and after the test. And if you don't trust it or believe it, it also happened to be open source. In the end, you were better off with Cliqz than without. Third (and maybe most importantly): If you don't support anyone who "collects" data, even if they do it in the most transparent way, without collecting any private information, in fact going a long way to delete all PII, open-source and with privacy by design, someone who has no business model built on collecting profiles, then you only criticize Google, but will never have an alternative or only alternatives that white label those that do collect all data. Because building a search without data is impossible. We were hoping that together with Firefox we would build a better solution. For some reasons this didn't work out, but lack of privacy was never one of them (lack of a business model more so, because sending every key press to some is more profitable than others, regardless of how private each is). In fact, our way of doing things is much more private than most people out there who claim to be private. This includes most browsers and search engines. And all of this is open source, so verifiable. And while we speak about it: In our blog https://0x65.dev we will over the next 24 days publish pieces on what we do and why we do it and why it is important, data collection and anonymization will be a big part of this. Last not least: All this is clearly not your fault, so my rant might be inappropriate, but as I said, this thing haunts us for the wrong reasons. (Me and the team are happy to answer any questions).

It was a mistake to have GLTDs other than the two-letter country codes. That would have ensured that the DNS namespace was partitioned in a way that mapped directly to legal jurisdictions.

I wonder whether the system can tell the difference between the driver using a mobile phone, and a front/back seat passenger using one.

One application is a thin window coating, you wouldn't need much of it. The manufacturing process is probably more expensive than the raw material.
How does showing up help any activist campaign? Participation in these decisions is tiny (sometimes unilateral - one retired lawyer can set a project back years), many people don't know about the issue or don't have an opinion, those who do have opinions aren't necessarily showing up to speak and vote for them. Everyone notices the cost of housing, but few realize it's a political issue that they even could vote about.

In general the story is broad and diffuse support for more housing, tightly concentrated and intense opposition to particular projects. There are many more NIMBYs than BANANA.

I'd like to see some real metrics. All the words are subjective and the technical ones are common to other databases as well. How many results can it return in how many seconds from a table with how many rows? Can it do full text indexing? Can it aggregate?

It feels like something from wallstreet, the language is almost pump and dump "I have this really great stock tip from this guy who made millions once, he's a legend. He says buy, so you should."

We need more tangible and quantifiable information about this database. Until then it's not even hype it's vaporware.
My take on articles like this is mostly melancholy. That lamp was somebody's baby, and it was put into production and then abandoned shortly after. This happens so frequently with inventions; they are abandoned until the original patent runs out, then later revived on a secondary patent by somebody else.

The silicon-carbide electrode version might give the material basis, if not the original technique, a second chance.

Great point. If you click through to savedotorg.org they say this:

The private equity firm hasn't earned the trust of the NGO community and the current caretakers have lost the trust of the NGO community. So what now?

So why not let them sell it and then found .ngo (or something like that).
Ask HN: Any good book recommendations for aspiring product managers?

I am not a Google search user so I am not sure what they are doing with "cards", however it sounds as though they are trying more to themselves become a "secondary source" (versus, e.g., just providing some "context" around the matched terms). The goal being that the user never has to leave the Google website.

For example, say the film credits for Spiderman is a "primary source", and a cast list for Spiderman derived from the credits at IMDb is a "secondary source". Google extracts the information from IMDb and substitutes itself as the secondary source.

Does this raise an issue in that ideally users should sometimes be retrieving information from (i.e., accessing) primary and secondary sources directly, whereas a third party always acting as a universal secondary source, e.g., a third party funded by advertising, might introduce (more) bias into the information retrieval process, e.g., in competition for "eyeballs".

This really doesn't make it clear what symplectic geometry... is, or why I should care about it. I have eventually figured out an answer that was satisfactory to me, after much frustration: it is math on a manifold that has a concept of paired-off coordinates, like (x,v) in mechanics. Typically this is interesting because it is an alternate characterization of the mathematics of a space where the relevant quantities are a variable and its derivative.

(In classic mechanics, particularly, there is an unusual symmetry to position and velocity, such that the laws of mechanics look roughly a rotation x -> v, v -> -x, which is why this works so well.)

As far as the corporate koolaid, all of corporate america isn't like that. You certainly won't hear managers bad mouthing the company but a lot of good environments, they don't repeat propaganda like phrases again and again. Even if they all mean the same thing they say it in their own way. Like for example they'd talk about their experience and what they have seen first hand that corroborates the corporate message to workers. And in some places, dissent (non-toxic but productive) is encouraged so workers feel like their voice matters.

At the end of the day happy workers have best ROI. You can acheive good ROI regardless but there will be long term costs.

Basically, GaN has less electric resistance than silicon. They generate less heat when used in high voltage (or amperage, depending on your viewpoint) applications.

We can't make GaN transistors nearly as small as we can make silicon ones, but transformers/chargers don't need many transistors in them, so it's fine.

I know that "silicion" isn't just pure silicon given dopings but I can't help but ponder the environmental and toxicological differences between the two. Gallium nitride seems loke it might be more toxic and gives me a sneaking suspicion they will be a "compact floreacent tube" solution that is a flash in the pan decade standard that gets replaced by something far less toxic anyway (LEDs). However I know that I don't know the details so I cannot judge only raise concerns which I hope were already addressed.

I understand the logistics issues involved in standardization of repeatably used sockets but USB chargers are so very "unhygenic" from a security perspective. Proper design from the data end shouldn't allow any unexpected changes but that is error prone in practice. It is sort of like sharing cups - in theory the immune system should take care of any pathogens but in practice it is a needless risk.

Getting into engineer dreams, an ideal design would involve readily apparent subsets between charge and data pins even if they occupy the same socket. So any charger honeypots to plant or extract data would be obviously untrustworthy.
