I have had similar issues with selenium via other languages too - it is generally pretty flaky. E.g. saying a button or some other element doesn't exist when it clearly does.

With great care and effort you can make your tests reliable (especially if you are happy to allow a "best of 3" type test strategy to allow for 1 flake and 2 passes) though. Prodigious use of the wait (i.e. stdlib polling) primitives seems to give you the most bang for your buck.

I am note sure if this is just the nature of web automation, or if selenium is just crap? My gut is to say it is selenium's fault since we never get the same issues when using javascript in the DOM or in an extension)...maybe it is the browser APIs I guess? U have no idea but if this playwright is any better than that would be superb.

It also depends where on the West Coast you live, of course. It's more of a city/rural divide.

I live south of Seattle. Seattle is restrictive, everybody outside is wearing masks, many restaurants are still take-out only, business are open for limited hours.

But you go 40 minutes south to, say, Puyallup, and the COVID restrictions are much more relaxed (if present at all).

Somehow I had an impression that web developers in general are aware of web APIs: stuff like fetch, DOM events, forms and URLs - all things this article lists.

Modern React development doesn’t deal with these things much not because devs don’t learn web APIs but because most projects use various component libraries that abstract web APIs from devs. You as an app developer do a lot more work to glue components together to achieve the desired behavior and you mostly deal with data management.

I don’t say Remix is bad, it’s an impressive piece of technology for building interactive UIs that tries to blend server side and browser side of web in a neat package, quite successfully I must say! It’s very pleasant to work with, not hard to get into, and I personally haven’t found any big drawbacks. I’d recommend it for all sorts of projects!

But this whole “we do plain web APIs” marketing angle is IMO strange and misleading. Remix is a set of APIs on top of React, you will be building React apps with it, with JSX, hooks and everything else. It’s NOT a vanilla web, far from it.
You would take that risk, everyone you know will take that risk, everyone they know will take that risk....

\ Just like honey from the bee

>The many versions thing does seem like a problem just in terms of size on disk but perhaps a one solution to this would be storing the libs as a series of git-style deltas starting from a root version which are then 'resolved' on the fly.

Just sending the scripts with the site is still far, far simpler, and guaranteed to work (provided the user hasn't turned off JS.)

What little, if any, gain in performance doesn't seem worth the extra complexity.

I think it's unreasonable to expect any solution to work for 100k years. Too many unknown unknowns. But hopefully if it does fail in say a few hundred years the radioactivity will already be less and they will be better equipped to clean it up.
Even helicopters burn fuel like crazy when hovering out of ground effect, and the only reason we use them are their huge main rotors that get some of that efficiency back when actually moving at speed, and also because they're the only thing available.

Anything fighting gravity with pure thrust is basically DOA at this point, and double that for inherently inefficient propulsion methods like jets. Ducted fans, maybe, but most likely not. And that's still allowing for fossil fuels and huge fuel consumption. Bring batteries into the equation and you can forget about personal VTOL for anything longer than five minute hops.

One common question of this type (I've had it, and heard a few others as well) is: implement a function returning the factorial of its input (so n!). Basically FizzBuzz.

I've done some thinking about this, and a possible solution is a bunch of cross signed CA's like the Federal common policy / FPKI for cross trust amongst federal agencies, but done at a state DMV / DPS level. Driver's licenses / state IDs could have certs embedded into the cards and then be used for things like accessing government websites, banks, etc. Yes there are some access concerns, and some privacy concerns that this is in essence a national ID, but what we have now is horribly broken, and we're already being tracked. We get all the downside of pervasive tracking, but none of the upside.

No, but I trust the people I regularly interact with and therefore allow them to be in my home. Nobody trusts people just because they happen to be in their home. To the extend that trust can go to “zero”, my fear is it will harm the (existing) first form of trust, which is vital, and have little impact on the stupid latter definition of trust.

I know tech operates on different definitions/circumstances here. That’s why the word ”zero” is so wrong here, because it seems to go out of its way to make the claim that less trust ks always better.

Call it “zero misplaced trust” or “my database doesn’t want your lolly”, whatever.
Why doesn't that sound great? Why shouldn't everyone be able to have places for themselves? This is more or less the entire premise of private property.

This argument goes right to its ultimate logical conclusions so fast its unbelievable: From the question I just asked it can be presumed I'm 100% fine with discrimination at scale in society. I am not. And yet, should the federal government be allowed to create women's shelters? Or men's bathrooms? Or urinals which are explicitly discriminatory based on your biology? Of course.

Some nuance has to come back to the conversation around discrimination. Honestly, it seems rather simple to me, although I always hold my breath and wait for someone to call me a horrible person: discrimination should be legal, and we should also lampoon and publicly mock bad and stupid discrimination.

If we aren't allowed to mock anything, if we all need to respect each other, then we _need_ anti-discrimination laws. I'd fight for anyone's right to deny anyone else access to their home. I'd still think they're a huge jerk for not being nice to their neighbors.

Anecdotes become data at large n sizes. :) Also, if you’re theoretically vaccinated, wouldn’t that mean you don’t display symptoms if you contract the virus?

I think it's possible to write tests in selinium which are time-independant... Eg. "Wait for element #foo to exist".

You can also give the browser a virtual clock so that you can use time based timeouts and give every test a timeout of 3 hours, but those 3 hours only take milliseconds in real time. That approach gets CPU expensive if your site has any background polling scripts or animation, because obviously the animation will end up animating a lot during the test!

> The passengers do not allow the pedestrians to live or die. It's the pedestrians who allow the passengers to drive around among them in the first place. All vehicles must therefore protect pedestrians first.

I disagree. The car knows there are human passengers. The car does not know that obstacles it detects outside of it are necessarily people and not, say, fire hydrants (although it may have a probabilistic estimate of their "peopleness"). Therefore it should prioritize the lives that it knows are actual people.

I get the argument, it really is a difficult ethical question. Your argument fundamentally boils down to "the car exists in the world and should move through it causing minimum disturbance to it" and that's a very sensible argument.

But, quite simply, if I'm paying for a car or a ride, the machine serves me. My argument fundamentally boils down to "the car exists to serve it's passengers first and foremost" with the caveat that human lives are more important than animals. It should do everything in it's power to avoid hurting anyone, property be damned. But, when the choice is protect people in general or it's purpose for existing, I disagree with you. I'm always open to changing my mind however, and I don't dismiss your point of view out of hand.

Do parachutes help when you lose control 50ft off the ground? Deploy time is probably too short. Also lateral speed may be fatal enough with a jetpack.
I currently live in Argentina, the loss rate is much higher, between fees and the official exchange rate you lose about 65% of any income you perceive. Aside from crypto, Payoneer is also popular (you go outside the country regularly to get cash).
> What were we expecting from jetpacks though, really? Is it not more fair to suggest that the past was a little bit naïve about what it would take to operate a jetpack? They're still aircraft after all, at the very least you're going to need pilots license.

You need a pilots license, but you don't need fine motor coordination skills across your entire body PLUS a lot of core strength, in addition to all the problems with moving in 3d.

For this 'jetpack' you are essentially balancing your weight between your back and arms. If you get it wrong for a split second, you'll kiss the ground. It's inherently unstable and tiring since you have jet turbines strapped to your arms.

An aircraft is stable. Let go of the controls and it will keep flying.

The closest aircraft comparison would possibly be with a hang glider, except even there your weight is supported and you are essentially just shifting it around.

Many jetpacks in fiction were envisioned to work more like drones. Tell it where to go and it would do the rest. Iron Man would be similar to this thing, except it is described as a fully mechanized suit (plus artificial intelligence), which magically takes care of some of these problems.

Ultimately, 'jetpacks' will probably never exist. There's an inherent physics limitation when trying to strap a whole human body to the side of something small (and generally depicted as being strapped on your back, Bobba Fett style). The center of mass is off.
A randomized study was run in Bangladesh. There they handed out masks to randomly selected villages among a pool of 600 villages with similar vaccination and political stances.

That study showed that the effect of surgical masks was statistically significant when used by the elderly 50+ population. For other age groups and for cloth masks, the advantage was statistically insignificant.

All the headlines around this study, including from the CDC were basically 'Masks proven to be effective!', 'masks work!', but that's a very lax definition of effective.

Irrelevant - a CIO's job isn't to be a hands-on coder, it's to set a strategy and manage an organization. Companies do a good but if due diligence on that, which is why it's really hard to break into the executive ranks - you have to find an opportunity that can grow into leading a large team because no one will hire you to do so if you haven't before.

Purely by chance, the last place I worked that had a CIO title, my LOB CIO probably would have had a good chance at passing a Leetcode interview, despite managing 10,000+ people.

I have two general reasons that I think are salient:

The public is terrified of nuclear and governments are responding to that.

The electorate is structurally incapable of asking for slightly more people to die in order to avert huge numbers of people dying. Therefore “more nuclear” is not a valid option even for many that think there is existential risk from climate change.

In an ideal world we would be able to quickly phase out gas stoves, but we live in a world where a company can pour a few million dollars into social media, create a new conspiracy theory about induction stoves and an equivalence between gas stoves, traditional values and not being a namby-pamby sheep.

In an ideal world the government would also ensure that everyone can afford a new induction stove, even if the tax payers have to chip in, because this is literally the best use of money. But again, a few million dollars, conspiracies, this is communism and so on.

The ideal world would still let us screw each other over, but it would let us do that for millions of years instead of decades. Sustainability is everything, the rest can be fixed later.

That's enough to reach critical mass of many fissile elements. I wonder if it would be possible to build a miniature nuclear rocket with enough thrust to lift a human. The weight budget probably isn't enough to include enough shielding.

The Canadian court subscribes to the living tree doctrine, so it doesn't really matter what his thoughts were at the time of signing.
It _is_ special but we cannot perceive it correctly. We do not have an absolute sense of "down" (and our absolute sense of "forward" and "backward" are based on a assuming fixed "down").

We sense "down" based on assuming that 1G of acceleration is the "down" position. This is fine if you're stationary. This is fine if you're moving in 2d. But accelerate in 3d and all of a sudden you can get completely disoriented because the "down" you're latching on to could be any acceleration vector.

We _can_ manage this, but it is an acquired skill and we need instruments to help us. Pilots (and especially fighter pilots or astronauts who truly experience a lot of 3d acceleration) need to train for years to acquire this skill.

Can you imagine training an average person years just to _use_ a jetpack? That's why we have jetpacks and yet most people don't care.
Definitely a stupid question, because I actually have no idea how they work: can a solar sail be "tacked" so as to decelerate towards the sun, like a sailboat sailing into the wind?

(Setting aside the risky problem of getting this waste off earth and into space to begin with)
It actually works pretty well. Compression in the tape drives is certainly worse than what you could achieve by zipping before, but at least it works at line speed (which is a couple hundred megabytes per second). Factor in the fact that you often write out multiple streams in parallel from a single server to multiple tapes, and it'll become rather tricky to find a compression algorithm that keeps up AND compresses better than the drive.

And most enterprises don't really care if their monthly backup requires 10 or 15 tapes. And zipping it all up beforehand requires even more space on the primary storage which is even more expensive than a couple dozen tapes
> I don't see them as markedly different with such a small example.

Of course not, because we're talking about a fundamental change in syntax that affects more than just two-line queries. PRQL puts the SELECT clause practically at the end of the query, after every join, filter, and aggregate. If you only care about the output, that's cool too: just look at the end. But if I want to understand a query in SQL, I have to read the entire thing backwards, clause by clause! By contrast, if the SELECT is at the end, that's not much of a problem.

Now you'll come back and say "but it's the same if you care about context: just look at the end!" And that's where we differ. I care more about writing, debugging, and understanding queries, whereas you think it's more important that the column names are up front, even if it makes understanding a nontrivial query much, much harder.
Exactly. I have room in my back yard.
