I hate to “pull rank” but I have a PhD in mathematics so I’m personally well aware of all the nuances. Again my point is historical/pedagogical. Why should “pair numbers” or “double numbers” be the answer as the OP suggested? It’s not straightforward without getting into conformal mappings.

And why is two dimensions enough for third and higher degree equations? Were there a simpler geometric connection, you’d probably have a nicer proof of the Jordan curve theorem… but you don’t.

Not sure what you mean by pair of pairs… the OP said that calling imaginary numbers “double numbers” would clear up a lot of issues but that is not clear at all to me.
Agreed completely. I'm surprised someone deemed this fit to publish.

The entire post seems to miss the point of UI frameworks and libraries entirely.

The busiest air routes in the world aren’t the transatlantic ones but short routes in Asia. If you could make a 30 or 50pax plane that could fly for 1 hour you could serve a lot of the busiest routes to/from Seoul, Taipei, Jakarta, Singapore, Bangkok.

They are electric plane routes that aren’t replacing normal flights, they are replacing routes that should have been short-ish train rides (but weren’t, typically because of water). It’s crossings of very busy and narrow bodies of water between very populated areas.

Replacing even one of those top routes with electric would be a huge success.

Even if there is no viable path to 300 passengers or 8 hour flights, this has to happen.

You got me curious, so I dug up their patent. This is as close as they come to addressing it.

> Although not shown in the previous figures, the circular mass accelerator structure 150 may comprise a second exit port directly opposite the exit port 115 to capture the counterweight 135 that is released simultaneously with the launch vehicle 105 to minimize an imbalance on the motor at the time of release. The counterweight 135 may be a solid material, or a liquid such as water.

The use of a liquid is a curious idea. Perhaps it could be dispersed in such a way as to spread the force of the counter weight being released across a wide surface area? Like a small explosive forces the liquid out in all directions?

The other thing is that even if ES6 wasn’t already widely released and supported, developers already use upcoming syntax via transpilers. So even if this article was written several years ago before ES6, devs were already using ES6 syntax alongside the popular frameworks.
In my opinion the US not capitalizing on China taking the undesirable, low-skill labor is the miss. The inescapable future of humanity is full automation of low-skill (and potentially higher skill) jobs, especially manufacturing. Rather than lament China taking these on before the robots could get to them and pining for a long-departed past, America could have used this huge head start as an advantage and shaped society and the economy in support of this inevitable future.

Mark my words, those jobs are never coming back to American human workers. And that's fantastic, they sucked. Society needs to prepare for the future where there's more people than work to be done.
Honest question: how do you find this? You can spot some from experience in a field but I've often wondered if there is a more systematic way to identify such niches (so that I can mentally compare them and pick one that I'm attracted to, rather than settle for one that I stumble upon).
Damn, great vowel shift sucks.

Learning English in school was really weird.

Finnish as a language is almost entirely pronouncially composable. If you know how every single letter is pronounced, you can also pronounce any word.

In English there are all these silent letters, different pronounciations depending on the position of the letter etc. And the vowel shift: "a" written as "u", "ai" written as "i", "i" written as "e" etc.
I love the new Custom Elements api. Creating a new HTML Element is incredibly easy:

https://github.com/lindseymysse/custom-html-element/blob/mai...

This is my favorite feature in HTML / ES6.

I really love programming without pre-processors or compilers. It feels so much more immediate and clear. I think the browser is not just acceptable, but is really good these days.

One thing I have found among junior devs is they will know React really well but not remember things like how the box model works or basic HTML elements like the <br /> tag. This leads to all sorts of frustrating code for everyone.

What I would like to see is more designers writing pure HTML and CSS instead of working in vector editors. Our designs will get better when they understand what HTML is good at. I think custom HTML components are a great start to this.

Show HN: JavaScript presentation lib for the automation era
Hi HN,

a year ago I’ve released the early beta version of Presenta Lib.
After many iterations, here the version 1.0 with a focus on playing nice with the automation era.

https://www.presenta.cc/lib/

Feedback welcome!
> Every time JavaScript goes through a major update, we seem to repeat the same cycle. At first, developers are delighted by the new features. They move back to coding directly in JavaScript, and frameworks become less popular. Then, in the relatively long periods between releases, frameworks begin to offer new features and tempt developers back. Repeat.

The other commenters are covering this a bit already, but even the first paragraph just isn’t a true statement at all. Projects don’t suddenly abandon frameworks and rewrite their frontend stack whenever new ES syntax gets released. That’d be incredibly counterproductive.
The repl in Common Lisp is a persistent image that's actually running the program you're working on. You can inject functions, packages, change packages, debug, etc, all directly from the environment running the web server without restarting. It's more interactive development combined with hot reloading as opposed to a repl from other languages (though it does have a repl as well)
A seat belt is not quite the same. Both sure involve autonomy. However, not wearing your seat belt mainly puts your self at risk. A virus can spread to others.

As for externalties of like medical care sure not using a seat belt or taking the vaccine mean your more likely to need medical care. I will add though without seat belt your more likely to die at the scene. Thusly, how much more externalties not wearing a seat belt will cause I don't know, and would need some data on that point.

There is also an other big difference between a seat belt and vaccine. Mandating a vaccine is forcing someone to under go a medical procedure. Albeit a simple one. Where as a seat belt does not.

Although, bringing up seat belts I find it funny we allow people to drive motor cycles on public roads, but you must wear a seat belt in a car. So clearly this was not just about externalties. So the rule seems quite silly to me. (probably the car insurance lobby pushed for it)

In my honest opinion it would be better the state did not mandate either of these in my opinion. What is sad is the vaccine some how has become political, and people are not taking for either stupid reasons or believing false hoods. Despite this I don't think we should be quick abandon principles of liberty because of idiots. Every precedent set today can be used to forward an other one in the future you may not agree with. So best tread carefully.
I presume the rent-a-cop portion was more concerning. One of the security companies they're working with has a pitch line that says if someone is outside your building screaming, they can come make them stop.

It's one thing to offer defense services that follow you, but it's concerning to think that your neighbor or ex or stalker could soon call Nextdoor to send goons to your house.
> I don't understand why America, long a champion of immigration, doesn't open the floodgates back up.

America has never been a champion of immigration, and honestly I don't really remember a time that the 'floodgates were open' so to speak, and it's not even a partisan issue. The last major immigration tightening was Bill Clinton with IIRAIRA in 1996 while the last amnesty was Reagan in 1986.

Don't take my word for it, here's what Benjamin Franklin, founding father, had to say.

"Those who come hither are generally of the most ignorant Stupid Sort of their own Nation, and as Ignorance is often attended with Credulity when Knavery would mislead it, and with Suspicion when Honesty would set it right; and as few of the English understand the German Language, and so cannot address them either from the Press or Pulpit, ’tis almost impossible to remove any prejudices they once entertain." - Benjamin Franklin, 1753.

Tell me that's not a highfalutin 1700s take on "they're not sending their best, folks."

That doesn't need people, it needs robots. The factories of the future have zero people inside.

While I mostly agree with you on this post being ridiculous and anachronistic but I will contend you on:

> Language syntax has nothing to do with framework features, and especially things like writing UI components, managing state, and updating the DOM.

Think of how much less useful jQuery is in 2021 than it was in 2008. That's largely because the language has advanced. The set of things that a framework has to solve has shifted because a larger set of those things can be consistently and easily handled by the language itself.

These days most of what a framework does is give a consistent approach to allow for simpler collaboration. Maybe an argument could be made for building against a framework in order to easily access plugins or things like react native? I almost never use frameworks of any kind anymore and I think a solid style guide could replace the value of a framework in many cases.
Dems were given complete control this last election.

The GOP has only the say Dems chose to grant them, and Dems chose to do that rather than take action on long overdue policy backed by majority American support.

That speaks volumes to Dems actually being about class, and even more about how Dems often run on class policy then govern well away from making any of it law and blame jaded voters, who have seen all this before, for those voters lack of trust, disapproval, and tepid vote turnout!

Those voters ask a simple question, "vote for what?" to which Dems have wagged fingers while giving non answers and lame excuses.

And let us be clear: the obstruction in play exists because Dems made bipartisan legislation a higher priority than those voters who gave them full control only to see it handed off like a hot potato.

"Willing to sacrifice"

Sorry, haven't seen it. At all.

Finally, the issues are not partisan at all. People of all political alignments are struggling. This is why populist solutions to these issues are enjoy majority support. Far too many people are impacted for it to be otherwise.

Neither party appears willing to act, and that is why we keep having change elections that result in basically no change.

Some silly questions if you don't mind.

1. Up thread people talked about electric ultralights as held back by FAA. Presumably your flights are in different t jurisdiction (Lima etc). Are there enough "pro" jurisdictions to compensate for the FAA "anti"

2. Your propeller (mounted behind you) seems to regularly cut out. Is that a planned thing to save energy? just a series of push then glide?

3. What is needed to go from this to something like regular service ? What is missing from this aircraft ?

I think it's 'pored over' not doing enough work. I pictured him sitting there, very focused, watching the footage and thought, 'Oh, so he spent a week and a half on this'. But, thinking about it more, he's probably got to pay attention to each person for a whole viewing, replay anything worth including, figure out how to crop, zoom, and cut it together, and view drafts of the final product many times. No doubt he spent at least a thousand hours looking at that 60 hours.

We have an ongoing culture war because voter support for Dems is tepid enough for the GOP to win elections that way.

The tepid voting is a direct result of economic inaction for a long time now.

Ongoing economic inaction will continue to put social progress at risk too.

At some point, actually doing more than running on good ideas will meed to happen, or we run the very real risk of regression on all that.

And the remedy is really simple!

I'm aware that Databricks is a PaaS service, but what Databricks runs under the hood is Spark (with a few proprietary extensions). So your jobs/queries do require some tuning just like with OS Spark.

Spark has had SQL engines (SparkSQL/Hive on Spark) for a long time. Photon is just a new, faster one. Photon tasks also run on Spark executors only, so it's not independent of Spark[1]. Also, while it's proprietary now, I wouldn't be surprised if Databricks open-sources it in the future, like they did with Delta Lake.

This boss isn’t well meaning at all. They expect people (unlike what you said) to actually read all messages right away, no matter the time.

Because, as they also say, sometimes it might be appropriate to respond right away (“Or it could mean ASAP”).

If that’s the case, then the clear expectation is that people read all messages at all times, they just might not always have to respond right away (but in order to make that judgement call they have to actually read all messages).

This might actually be worse than just sending messages after hours where you actually have to respond right away – because you actually have to do sifting and filtering (after hours!) through messages, the vast majority of which might not require an immediate answer. If you are only contacted at those times where you actually do need to respond right away then at least you know what to expect …

This sounds like a pretty awful boss with awful communication who somehow convinced themself that they are oh so gracious and nice.

Well, in part because independent trade unions are illegal in China. And by "independent" I mean not a mouthpiece of the CCP. This is partly what I meant by reshaping the economy, though. Unions are there to push back against capital, but the adversarial capital v. labor system only really makes sense in a world where there's at least as much work to be done as people.

Of course all else being equal unions are going to look out for their members and their members jobs. It's that or the unemployment lines. However, the society of the future simply won't have those jobs. It will require some new and different social contract. UBI perhaps is an alpha.
While I believe that the problem is insidious, you're not bringing any actual evidence to counter the article. All you have is contrived counter-examples about other negative behaviors unrelated to the article. So you haven't added anything substantive to the discussion.
I remember this happening to me when I was a broke college student over a decade ago. I had to pay some bills and buy some things, and I expected a single overdraft fee, as I knew my exact account balance and the order of the purchases. I remember being hit with 3 (maybe 4) overdraft fees and immediately called my bank for an explanation. They gave me some bs like, "We reorder transactions to make sure your large ones go through first since they're probably more important." It was obvious at the time what they were really doing and why, which led me to eventually close my account with them and go with a local credit union.

In Python some standard operations are global functions and some are methods. Which are which isn't exactly clear. It's also kind of irrational and random but I hate seeing __init__ everywhere.

For example, to find the length of an array in Python you use the function len(). In Ruby you call the method .length. As the article is about, loops in Python are for blah in blah. In Ruby they're blah.each and for loops are just sugar (not sure why they're there but you can avoid them). In Ruby pretty much everything is an object and you just call methods. Very few keywords, global functions, etc...

Also, as the other poster said, if you call a[0] on an empty array, in Ruby you get nil, in Python it throws an error. Not sure which is better or considered more 'proper', but Ruby's behaviour is what I'd personally expect in a dynamic language.

For as long as I can remember the minute a vechicle (Hot rod cars basically) are modified to go faster, or different than stock; the public blames the guy who modified the car.

I really doubt the public is going to blame OneWheel for a product that was monkeyed with.

I felt for awhile now that if Tesla let home mechanics modify their Salvage vechicles; they would have brought more guys like myself into their product.

I know what you guys are thinking. Elon doesn't need anymore success. He might in a decade from now maybe. Getting guys who work on their own vechicles in his boathouse seems like it would be a good idea.

(Personally I don't buy anything I can't work on, or modify. It not even that Zen and Motorcycle Mechanics philosophy. It's about money. I'm poor, and can't afford to not repair my big purchases.)
Exactly. At a previous job we asked applicants about sort that had to satisfy some criteria like "more votes + same ration ranks higher" and "same amount of total votes, better ratio ranks higher" and (positive - negative) was the simplest solution that satisfied them all.

That is not to say that (positive - negative) is perfect, but just dismissing it because it doesn't satisfy your randomly chosen criteria is just lazy.
