This is really cool stuff, thanks for sharing!

I'm working on a desktop application which has feature to let users query data across a bunch of different data sources, like csv, excel, and some others. The way I've implemented this is by first scanning all applicable files and populating a SQLite database with all the data from these files, a table per file essentially, and then allowing users to execute queries against the database. The database is updated whenever any of these files are changed on disk, but any writes to the database are not persisted back into the files on disk, so it's really a one-way kind of flow. This was all implemented mostly as a proof-of-concept, but it's been massively useful so we're probably going to expand on it this year, perhaps by allowing bi-directional workflows.

Even if the use cases and approach is different, it's nice and validating to see other projects with similar thoughts and ideas. Again, thanks for sharing!
It is alarming to say that temperatures around polar areas increased a lot. That is where a couple of positive reinforcement loops are located (less reflective surface because ice melted, and the release of frozen greenhouse gases).

In fact, animations that show the average global temperature increase, or local, but by (alphabetically sorted) countries like this one don't let us see that trend.

Another mostly hidden temperature trend (that may have regional component too) is the sea temperature, as water is capturing most of the heat. And in part that is what is fueling extreme weather events.

You're right that if your team is filled with people that either don't know or don't care about quality, then no amount of automation is going to help. If corporate thinks an automated CI/CD managed by a separate operations team is going to bring quality, then, yeah that's always going to fail. But that doesn't mean all and any automated CI/CD pipeline is not going to help.

I've both worked with and implemented CI/CD pipelines, as in a Jenkins script that builds a number of build artefacts and then promotes them to run in a particular environment. As part of the build process, it runs automated tests and static analysis on things like type checking, code style.

What it doesn't do is tell us which tests we forgot to write so there's no 100% cast iron guarantee that everything is correct, and I think that's what you're referring to as "improved code quality". But by having that automated step, our human QAs can spend their time on manual exploratory testing (which humans are very good at) rather than manual regression testing (which is extremely slow and inefficient). And our devs can focus code reviews on questions like "is this code clear to me?" rather than "did you meet the in-house code style?" or "have you forgotten about potential nulls?". And we can bring in contractors (who might not care so much) or juniors with a fast onboarding time, since a lot of mistakes will get picked up automatically.

If you're working in a sufficiently large organisation, one where independent auditors look at development processes, then you must have a CI/CD pipeline - either a slow, manual one or a fast, automated one. I know which one I'd prefer.
> When do they occur?
When the code is run, not when it’s written.

> I'd argue that it is a good way, based on my experience of both methods.

And with similar experience, I’d disagree. Paired programmers are focused on writing the code not reviewing. The whole point of code reviews is to let someone divorced from the problem solving process objectively the code.

Facebook annoys me I have to say. And yes they are getting good at ads as I was recently trying to buy a used vehicle and kept searching the marketplace. Of course this starts Facebook's gears and I get more and more suggestions about cars people are selling more frequently. One picture really caught my attention, I forget why, so I clicked it only to realize a moment later it was a sponsored ad by Facebook.Oops

What annoys me about Facebook is now I have purchased a new car (and a phone a month back while we are talking about this) and I am constantly being bombarded with car financing ads and suggestions to phones I should buy. If only they could tell when to move on from an ad because I do not need multiple car/phones at this time.
Actually, the rideshare folks usually (depending of course on location and personal preference) are after the airport drives. It's the onesie-twosie "bar-hopping" short trips that they don't like.
These companies have discovered that there is a large market of people whose need for quick cash with no friction exists and is willing to lose money (in terms of car wear and tear) to do so.
I've almost completely moved to Qi charging my phone.

Oddly it took a while for me to find an in car CD mount type, as most of them are air vent types.
"Maybe more relevant ads would mean fewer ads and less revenue?"

Definitely not :)

Empathetically ... it's the opposite.

I see there's a bit of misunderstanding here about Google's, or any other platform's ability and willingness to show relevant ads.

Google is absolutely trying to maximise relevance for ads. That's not to say they won't take your money anyhow, but the unconditionally want your ads - all of them if possible - to be effective.

The economics of marketing are such that when a spend is effective, it's followed by considerably more spend. It shouldn't surprise anyone that when companies find a positive ROI, that they're willing to invest much more heavily in this.

Google is a business which is powered by ads, and relevance is the most core and effective measures of value of their product by their customers.

Again, in 2019, with all of the data they have, it's still really hard to target in a consistently efficient manner for almost all product categories.

Have you ever wondered why at the bottom of ostensibly respected entities like CNN you see clickbait for so many ridiculous, innocuous products? It's because the value of click-bait style targeting still transcends our ability to do meaningful targeting.

To anyone who's never worked in Marketing or bought any ads, I'd suggest popping $20 into Facebook ads and just running a couple ads for anything. Just like 'Music' seems to be one of those subjects that goes hand in hand with 'Computer Science', my hunch is that the human behavioural issues surrounding ads are one of those subjects as well. It's really fun. It's one of those amazingly complicated and interesting pockets of curiosity.

That is a very good question.

In general, what you can expect to see when visiting a Cloudflare site via Tor is a CAPTCHA challenge to authenticate your browser to show you're not a bot.

As to whether we can enable the `Onion Routing` setting, which would cause your browser to connect to Cloudflare via Tor and not via an exit-node, I don't know if we may enable it. There might be some compliance issues with that, which may prevent us from enabling that.

I have however created an issue on this for further investigation whether that might be possible: https://gitlab.com/gitlab-com/gl-infra/infrastructure/issues...
The duplication Issue can be solved in many ways.

First one that comes to mind is, the Issue Tracker should have a limit on the number of tickets a certain User can open.

If the Issue Tracker doesn't have that, then the company can have a firewall rule to only allow a certain number of calls per day to the API.

I'm sure there are dozens of other possible scenarios :)

The problem with principles is they don’t tell you much about consequences. We might all agree that we should help very poor people in region X, but what will actually help most? Micro loans, micro loans with coaching, unconditional lump sum cash at random, unconditional lump sum cash to targeted promising candidates, free schools, schools with small fees?

We can’t know how the different effects of these things compare from a principled argument. That’s where evidence is useful.
"That space doesn't have to be actually effective so long as it sounds convincing enough to you."

This is even more pedantic but no, service workers are not generally payed the legal minimum wage.

Wage theft by employers is over $20 billion a year (more than all other kinds of theft combined) and wage theft happens predominantly to those being paid minimum wage.

17% of low wage earners are subject to wage theft -- 2.4 million people just in the 10 most populous states -- and the average amount of theft is $64 a week. Which doesn't sound like a lot but is 25% of their weekly wages.

If I order a pizza, I’m using a communication channel (phone, internet) to place an order; one tool.

I deeply hope the pizza place is using chefs and an oven to make the pizza; completely different tools.

If I demanded the pizza chef make the dough, slice the ingredients, and bake the pizza with just a stand mixer... that’s just dumb.

Use the appropriate tool for the job and use the right level of abstraction at each step.

Under absolutely ideal conditions, a Tesla on a 250kW charger for 8.5 minutes can regain 40% of battery capacity [1]

So, if you carry 2.5x the battery you need, so a 40% charge is all you ever need, then maybe? Although obviously, that would add to your weight, reducing your range.

If you were willing to hook up a supply of cooling water while charging, you might be able to do somewhat better - one of the key limiting factors in fast charging is the batteries heating up.

I've read the original paper by Jaeggi et. al., one paper replicating it successfully and one paper proving the results transfer to different tasks. At this point wasn't it logically correct to say that's scientifically proven? Now we know there are papers which prove those proofs questionable. That's what I mean.

If only we had a bullet-proof test to measure fluid intelligence (classic IQ tests have quite a well-known number of problems, solving math problems and puzzles is known to be much more of a skill, working memory is working memory - not intelligence itself) objectively...

It does basic left/right aligning for strings/numbers etc.

It's a nice feature/idea but I'm torn between implementing it and also allowing you to do it in SQL...

I agree that concat('$', table.amount) as amount should be right aligned, but mine would leave it left aligned (as it became a string).

Well actually, I've been told that the problem of rail noise comes from improper maintenance of the rail track, not the motive nature of the cars themselves.

Rail requires periodic grinding to be maintained properly. When you see rail and wheels riding "flat" on each other, that's actually not how it's supposed to be -- that kind of maximum contact actually produces the squealing because the surface area has lots of opportunity to make friction-induced noise.

Supposedly, when you see a rail that's completely shiny on the top surface from being worn down, that's a sign that it hasn't been properly maintained.

A properly ground rail and wheel actually is only interacting on a very small edge of contact -- and this is what produces a quiet ride. A properly maintained rail will be quieter than almost any other mode of transport (noise from the contact surface). It takes active rail grinding though.

So actually, just a change to electric cars will not maintain quiet operations (although in the beginning I'm sure the newness of it will help). BART/Caltrain actually need to conduct the rail maintenance in order to keep it quiet.

Unfortunately, whether it's due to budget priorities being elsewhere, or an indiscriminate customer who puts up with this, unless that aspect changes, we'll be back in the same place. I don't even know whether the conductors -- the ones who would be among the first to notice such issues -- are even trained to understand this.

I encourage anyone to go ride the high speed rails of Germany, France, Italy, China, Japan, Korea, to understand what properly maintained rail is capable of feeling like. Or even the U-bahn in Munich, Frankfurt, too.
Unless they force people to take jobs at gunpoint (or change agreed contracts after the fact), no wage offered is abusive.

The company didn’t even have to provide anybody. There was always at least one English speaker at the bank, even though I could get by in Chinese verbally, it’s just one weird rule that requires me to write anything by my own hand at all (other than my signature). A lot of places are like that: they’ll easily take care of the paperwork for you if they know you can’t. Even for foreigners that don’t speak Chinese, they get by, especially in a first tier.
Maybe for a day or a week. How can they not realize when they have no money at the end of that?

Twice! They tried to land at the original airport again, it happened again, they cleaned it again, then diverted.

The pictures are intense!

Edit: The original title was way more focused on the fact this is a Boeing 737; I feel the new post title is a good compromise.

BTW: I think this is gaining traction because it's a 737; however, can most airplane windshield wipers clean a thick layer of dead, crushed locusts off the windscreen?

I would argue that we should change the title to "airliner." I think the title is meant intentionally to capitalize on the notoriety of the model of airplane, when this incident is not specific to that model.

What I find interesting about this finding: I wonder if intra-dentrite vs. inter-dentrite vs. inter-neuronal learning has different learning rates, activation functions etc. If that's the case, maybe artifical networks could benefit such variety.
Chinese writing is adapted to write the Chinese language. The only place where this is an issue is languages where there was no standardization (namely every other Chinese languages except Standard mandarin) because even natives don't know which character to use. More interestingly, once someone has knowledge of Chinese character, he can guess the meaning of text in other languages; for instance Korean written in mixed script is incredibly readable to some one with Japanese reading ability.

The Voyager Golden Record has a record of Minnan language which transcription in Chinese character is: 太空朋友，恁好。恁食飽未？有閒著來阮遮坐哦! Anyone in this thread reading some Chinese can guess accurately what the first sentence means. Probably the second too. The third is more difficult but looks like an invitation. Now compare with the romanization: Thài-khong pêng-iú, lín-hó. Lín chia̍h-pá--bē? Ū-êng, to̍h lâi gún chia chē--ô·! Besides pêng-iú looking like Mandarin pengyou is this totally foreign.

It should be noted though that the airplane type is only marginally * relevant in this incident (I'm saying that because many have other associations when a B737 gets mentioned in an "incident" context).

* The only relevance is that the ability to open windows / reach other windows to clean them during flight depends on the airplane type. So it's actually a plus for the 737, in this case.
Why Manhattan’s Skyscrapers Are Empty
Yeah, I get your point.

But everything was upside down with that team, not just payment. They had a completely different philosophy when it came to software development.

For instance we were encouraged to just close tasks. It didn't matter what we did as long as the build and code reviewer were happy.

Part of the philosophy was that if developers can abuse and break the project, the project is not good enough and must be toughened. Then, developers were encouraged to find other loopholes.

This methodology worked wonders for small projects, libraries. It didn't go well for big projects, obviously.
