I think I just need to try out something like Agda before I make any more claims :) Does Agda have something that can automatically prove small formulas in e.g. pure predicate logic?

Backwards reasoning works something like this: to prove 'forall n: P n', it is sufficient to prove 'P 0' and 'P n => P (succ n)', so if you have 'forall n: P n' as your so-called proof goal, you can use the induction tactic to transform that into two goals: 'P 0' and 'P n => P (succ n)'. You then have to separately prove both goals. The tactic system then basically build the actual proof by putting everything on a stack and applying in reverse: once you've proved both goals, it knows it can apply the forward-reasoning induction proof function to construct a proof of the original statements from the two proofs you gave.

> the difference between agda and Coq seems like the difference between purely functional and imperative programming.

Bold, bold :) I'll have to try Agda before I can comment on that. Coq proofs do seem a bit inperative, so there's that.

>I don't get why so many people tout discord as this god send of a service.

It's definitely not perfect, but it's essentially the modern IRC - fast and easy to spin up a server for any community, decent moderation tools, scripting via bots, rich media support, and continuity across different platforms.

I definitely wish they exposed client apis and sanctioned 3rd party clients, but this is likely at odds with their ultimate business model.

CLEAR is not Pre.

CLEAR is "skip waiting in line for a person to look at your ID and boarding pass". That's it. CLEAR by itself still sends you into the unpack-your-bag, take-off-half-your-clothes, body-scanner experience.

If you want to leave things in your carry-on, stay fully dressed and use the metal detector, you still need Pre (or another program which grants membership in Pre). CLEAR does not give you Pre.
What about American innovation that relies on certain parts from China, such as the entire electronic industry which we operate in?
I've wondered if this is part of why politicians are so long winded and won't directly answer questions. Not just so they can appear neutral and avoid answering hard questions, but if they actually say something meaningful in a few words it will probably be taken out of context and used against them.

Plus beyond introversion, controlling and dominant people make everyone suffer during pairing. Also, shy people non-assertive people loose any possibility of autonomy or independent decision making (they might or might not find it uncomfortable). People who see everything in absolutes are hard to pair with and find it stressful. Extroverts who still like to think about problems silently or explore issues cant do that in pairing either.

The human social issues related to pairing are many more areas then just introversion extroversion.

What I don't understand is why? Is it in response to an increase in plane hijackings in the US since 9/11?

Unless the terrorists board with machine guns, 9/11 wouldn't be possible today. No passenger would assume that a bunch of middle eastern hijackers have any other intention than to kill them all, and it would be impossible for the hijackers to control the passengers.
They should pay the cost of shipping their parts from China to the US without a subsidy from the US taxpayer.
I am not a native English speaker, and it's the first time I see the world "ennui" (pronounced "An-we").

You have associated it with boredom, and you made me instantly realized that "ennui" is surely related to the Italian (my mother tongue) word "annoiato". Quick google search, and in fact it comes from the French equivalent of annoiato.

This means that when I translate "bored" with "annoiato", I am actually doing a (super common) mistake.

It's super interesting how words between languages have slightly different meanings, but sometimes these meanings are altered without us realizing it.

Deflation doesn't mean cheaper food and shelter. Remember, deflation reduces the dollar value of labor, too. But the dollar-value of all other goods and services decreased tenfold as well so in the end nothing has changed. However, there's one big factor you're missing: debt.

Simply put, inflation favors debtors while inflation favors creditors. Imagine you bought your house with bitcoin, and took out a mortgage of 500 bitcoins to pay for said house, back when bitcoin was $500. Total debt, $250k. Now, the price of bitcoin is over $6,000. Did your loan magically shrink from 500 bitcoin to ~42 bitcoin? No, your loan is still 500 bitcoin. So your $250k mortgage has become a $3 million mortgage.

So inflation hurts people that loan out more money than they owe: mostly banks and rich people. Deflation hurts people that owe more money than the loan out: poor and middle class people. Benefiting the wealthy at the expense of the poor is broadly considered to be immoral. An ideal world might see zero inflation and zero deflation, but predictions are always off so the Fed plays it safe and targets ~2% inflation.

You’re paying the costs, just indirectly via taxes and artificially higher US shipping costs.
Right. But how much? I'm not from the US, but I know that the expectation is to tip. And I do. However, every time I leave some place I have this vague feeling of unease and guilt - technically I could have afforded to tip more. Was it enough? Did I offend them by accidentally calculating 15% instead of 20% ? Is the norm actually 30% in that place?

It'd just be so much easier if it was already included in the price.
Aren't we still paying for shipping through taxes, since the USPS is a public institution?
What will be the unintended consequences I wonder?

Small businesses who use dropshipping direct from Chinese companies will stop being able to compete with big businesses who buy in bulk and ship from US warehouses. This will benefit the likes of Amazon more than anyone else.

Not sure if that's an unintended consequence though.

This is for a US based university.
Have not attended that many university's to be able to do an actual comparison, but here is the info for my alma mater. Additionally I studied CS, but I know they have a good EE program as well.

The school is California State University - Los Angeles (CSULA). It is an ABET accredited school.

If you are just looking at tuition it runs $6,744/ 2 semester year for California residents. Estimates for a non-resident living on campus run $35,638/ 2 semester year.

It is completely driven by senior developer. Many students find such pedagogy demotivating. They are not getting tasks they could solve autonomously and independently, every their step is watched as they are doing it. So, they don't even have chance to make mistake, realize mistake by themselves and then fix it. Imagine college classes done that way - everyone would rightfully complain.

Motivation and desire to learn are partly function of personality and partly function of environment.
The idea of free trade/globalization is everyone benefiting from the efficiency of each place doing the work it can do most efficiently. Iowa corn and Swiss fine machinery and Arab oil and all sorts of things where one place can do something better and cheaper because of the nature of the place. Poverty (cheap labor) and treaties (cheap postage) shouldn't be the drivers of this efficiency because they aren't caused by fundamental differences, just political ones.

Perhaps relay the email out via your ISP account? I do that and it works well.

> Having email just down for a couple days while you wait for new hardware to would be a very bad experience.

Perhaps set up a fallback MX that directs traffic to e.g. a Mailfence account when your primary MX is down? Works for me. Also, mail servers can be cheap hardware (an old x220 will do).

Which isn’t a bad thing. Maybe we’ll see less spam drop shipped items on Amazon finally. eBay too.
You'll still have to pay that price, but now a Chinese company will have to pay 25.00 to mail a small book to the US as well. This is just going to limit the sale of small goods internationally.

It does require having to leave the treaty - if the UPU Congress refuses to reclassify China. The threat to leave, is meant to apply enough pressure to finally get that reclassification accomplished. They've been intentionally dragging their feet on this matter over time and they only meet under normal circumstances every four years (they can of course hold emergency sessions).

It's the exact same problem the US has had with the WTO, it has refused to do anything about China's dramatic state sponsored dumping for more than a decade. These are global bodies that are invalidating themselves by refusing to normalize rules for China now that they're a massive economic power.
Why does the US have to withdraw instead of negotiating? The US are not the only country that is unhappy about the shipping rates with China.

The postal treaty however is hugely important for smaller countries. I don’t want a world where the US destroy the entire postal system for the rest of us.
seems like this will backfire if we ever want to access the emerging Chinese consumer market.

Good post. The Snapshot-based approach during ingestion time was the part where I couldn't figure out why it was considered a good decision during implementation?

I've experimented with Parquet data on S3 for a work POC, and the latency to fetch the data/create tables/run the Spark-SQL query (running on EMR cluster) was quite noticeable. I was advised that EMR-FS would make it run quicker, but never got around to playing with that. But I guess the creating of in-memory tables using raw data snapshots would still remain true? Or maybe I missed something.

Also, I take it if 24 hrs is the latency requirements for ingestion to availability of this data, obviously this isn't the data platform that is powering the real time booking/sharing of Uber rides. I'd be curious to see what is the data pipeline that powers that for Uber.
Of course you realize that this change will likely disproportionately affect the poor and middle-class (who will see a sharp rise in shipping costs) as well as smaller businesses who rely on thin margins to survive.

The cost of $300 million per year as quoted in the article seems like peanuts compared to some of the other actions this administration has burdened tax payers with.
You would have to pay more actually. The cost for both the USPS and for China Post.

The things you see on Amazon are bought by the container-load from China and sent to Amazon's warehouses for fulfilment. This change will encourage that sort of business because it'll no longer be worthwhile sending direct from China (as the likes of dx.com and aliexpress do now).
The article says that withdrawing takes a year and they want to negotiate during that year so the withdraw doesn't happen.

Actually, those guys have collected both tax data and spending data. They show very well that the older, poorer parts of cities universally collect more in taxes than they spend on services, and the surplus subsidizes the richer suburban areas. If you have any data at all showing the opposite, I'm sure they would love to see it.

I heavily dislike that america just leaves treaties it does not like instead of improving them. Most smaller countries cannot use the same method.

If my country for instance were to do thay nobody would ship there any more because the billing system would be too complex and expensive and the market is just too small.
Because Trump is scary!
That is what it means, but it makes tippers feel better than if it said "no tip"
The threat of withdrawal is part of the negotiation as far as I can tell.
No, generally speaking those businesses purchase their orders in large quantities that don't arrive by individual small packages.

This would end an absurd international postage welfare program that China benefits from, pretending to be as poor and developing as they were 30 or 40 years ago.
Incorrect, I live in Australia.

This kinda reminds me of the conversation I had with my brother in law regarding the likes of SingAir, Emirates, and Qatar and just how much better they are when compared to US carriers that charge more on the same route despite providing an inferior product comparatively. He started on about how those air carriers are government subsidised, it's not fair, and I shouldn't be flying with them because of that. I told him I didn't care about the underlying business model, I want new aircraft, well trained staff, good quality food as well as service. Every one of those government subsidised carriers over deliver on every one of those metrics when compared to their US equivalents.

Sure, some people will take a stand because they feel the need to do so. But in general I don't believe most people care how their goods and services are subsidised, only that they believe they've received a better deal when compared to similar offerings from other providers.

fwiw Skype is now an Electron ("resource-hogging Chromium browser" and all) app, too.
Actually, just whatever 'ssh' binary is installed. That is not necessarily OpenSSH, but it is the most common choice.

Sure, but America can, so why shouldn’t it?
I don’t get the Electron hate, Visual Studio Code is probably the best IDE I’ve ever used, and it runs much better than eclipse or even Visual Studio ever did.

Saying this is a little unfair to Visual Studio, but it’s just so bad when you’re in an enterprise setup where you don’t really have a local drive. Visual Studio code on the other hand doesn’t care if your windows profile is on one network drive and your code is on another. Which is a little ironic because I think you’ll see code more in small setups and regular studio more in enterprise.

Anyway, I think electron apps work fairly well. I don’t like discord, the company, but discord itself works and feels a lot better than Skype, teams peak or ventrilo.

> Despite being an open language, Swift (and Playgrounds) is an effort to usher children into the Apple tent.

Yes. That is certainly a good argument against that specific example, and it is one I agree with. But it does not apply generally.

> To suggest discrete logic and IC-level assembly compares to issuing commands via the LEGO Mindstorms protocol perfectly illustrates the chasm between learning and understanding.

But learning and understanding what? Why is it (as I imply that your argument is) important to understand assembly-level instructions when it is not important to understand the underlying electronics? Why is this level special?

In addition to all the general arguments I outlined above, there is one additional argument to be made against assembly language: In today’s processors, I am given to understand that these assembly language instruction sets are largely a high-level language, emulated by microcode – the assembly instructions you write have very little to do with what the processor is actually doing in a modern hardware architecture, and therefore teach you exactly the wrong things about how a modern processor works.

A _huge_ chunk of Amazon is low effort Chinese clone / drop shipped crap or straight up forgery. I don't feel sorry for /r/entrepreneur denizens' loss.

It will help the kind of small business with core competencies revolving around producing things and hurt the kind of small business with core competencies revolving around buying things on Alibaba and selling them on Amazon.

People who actually wanted to do things well often couldn't even afford to ship their product for the entire price of product + shipping for lots of dropshipped things under the old ways. I'm happy that the class of business that monetizes outdated shipping policy are going away.
You know this, and you've apparently experienced this several times. So maybe stop wearing boots when flying? I always carry a pocket knife, but not when flying. Not just because I want to avoid anal probing, but also out of courtesy towards everyone who is behind me in the security theatre queue.
15% was not catastrophic for those of us old enough to have lived through rates that high. Just different. Unless the devaluation of a currency actually matters to you. My country has had a currency devaluing for well over 100 years, in high and low inflation, so the point is mostly moot. Wage rises were aimed at say 5% ahead of inflation as anything smaller would instantly get eaten. Mortgages inflated down to pocket change, so after ten years of mortgage the percentage of your pay that went on the mortgage was so low it felt like housing became essentially free. You didn't keep £20k in a savings account as inflation would chew into it quickly, despite the account maybe paying 12%.

Deflation means everyone is putting off all possible spending. Why buy that car when it'll be cheaper next month? As companies react to lower demand they lay people off, which increases unemployment and adding more deflationary pressure and reduces demand further. When enough companies have laid enough people off few are going to risk starting a company, as all the money in the economy is under mattresses waiting for things to get cheaper.
