I would argue the MacBook Pro. Taking out the SD slot (so you can't expand storage, and have to buy a more expensive or replacement machine) and replacing the function keys (with a Touch Bar, which looks good in ads but sucks to use) were driven by marketing/sales people, not product people.

This machine is awful to use and I'm in the processing of researching something to replace it with.

I would happily switch back to a 2015 model, even with the drop in CPU and GPU power.

I actually like typing on the butterfly keyboard, I'm doing it right now - but it has reliability issues.

They also took the headphone jack off phones - making it a worse device, because the AirPods/HomePod marketers didn't want anyone plugging their phone into their existing headphones or speakers.

The awful mess they've made of Lighting/USB-C ports on different devices is also confusing and irritating.

I wish every device of theirs had the attention to usability the Apple Watch does. That thing is a pleasure to use, it's just expensive and incompatible with Android. But the way they're going, they'll put a verification chip in the strap, to make sure you have to buy those from Apple too.

Unfortunately they have by far the best chips, trackpads, and smartwatches on the market.
A millenia later, humans will look back and wonder the same about how we did math on decimal system, while binary is far superior. I expect they will even genetically remove one finger from each hand so they can do binary math better with their fingers
I read a lot on this topic, and while I don’t disagree some people are dealing with serious long term effects, your assessment is wildly overblown and offered without qualification. I’m aware of cases that are dealing with serious short to medium term effects. There’s no doubt this is real, but the likelihood of their occurrence is a topic of research. Furthermore, the 1+ year outcomes have not been measured in any meaningful way. Conjecture is not evidence.

Salt Lake already looks to have a better AQI than LA[1][2], though, and pretty much every new car sold is 50-state compliant (which includes CARB).

So, Utah has already effectively adopted CARB standards, and the rest of your suggestions fit in the same category -- I don't see them making a difference, or being feasible.

Show HN: We created a User Onboarding tool- Giving 21 day Unlimited access
Accountancy is(was?) widely taught in South African high schools. It was certainly quite common in the 1990s.

I found it quite amusing when I realised that double-entry isn’t widely understood around the world, a realisation I came to after I first encountered one of many confusing “accounting for developers” posts on HN.

It was quite easy for us 13 year olds to grasp:

Assets=owners equity +liabilities (accounting equation) A=O+L

Rules:
Left side of equation:
Increase in an asset: debit.
Decrease in an asset: credit.

Right side of equation:
Increase in liabilities: credit
Decrease in liabilities: debit

Increase in owners equity: credit
Decrease in owners equity:debit

Expenses decrease equity, income increases equity. Capital increases equity.
Drawings decrease equity.

For every debit, there must be a credit. Every transaction fits into this framework, and every transaction must balance the accounting equation.

Your bank statement appears to be reversed, because it’s written from the perspective of the bank: for them, a deposit by you increases their liability to you (a credit). Similarly when you owe them money, it’s an debit, since from the bank’s perspective, your debt is an asset to them. (Bank reconciliation is another thing we did in school.)

This really isn’t rocket science.
All those things have been or can be fixed. They're still moving massive amount of products. I'm no apple apologist but you're overblowing things.

This is my go-to everyday watch. Have had it for over 10 years and it never skipped a beat. I've had dozens of watches cycling through my collection throughout the years, GW-M5600 has been the only one that I'd never considered letting go of. When the straps break, I'll just go with a good black Nato strap. If I had somehow lost this watch, I'd buy another one without hesitation.

My only real complaint is the countdown timer is only 1 hour. There are times I could use a 24-hour countdown timer.

A minor nitpick is the watch's thickness is just a tad too think to be worn under shirt cuffs. If Casio would ever release a 25-30% thinner version with the same features, I'd buy it in a heartbeat.
My household got presumed coronavirus in March. I say presumed as no test available.

First the nanny, then my wife, then me. I’m male, late thirties, workout daily (or used to anyway). I got it worst and spent weeks 2 and 3 in bed struggling to breathe. But we mostly recovered.

Two months later in May, the symptoms came back, but milder. Again, my wife first, then me the next week. I only spent 3 days in bed. Again no test (we’re in the UK).

Well two more months have passed, and guess what happened last week? Again my wife first, now my turn. I write this from bed waiting for a doctor callback. Maybe I’ll get a test this time, but I expect it would be negative.

There is a lot of focus on the binary nature of living or dying from coronavirus. I hear many in the tech community wish they could just get it and be done with it. But there is a very large grey area between full recovery and dying. Even if you are young and healthy, you don’t want this.

Different countries have different corporate cultures. Differences in corporate culture are partially caused by differences in national culture. And, although I acknowledge it is a sensitive topic, I think differences in culture between countries can lead to differences in economic competitiveness.

The two countries I know the most about are my own (Australia), and the US. And I definitely see a lot of differences in corporate culture (willingness to take risk, thirst for innovation, etc) between the two countries, differences which generally come out in the US's favour.

I remember Elon Musk saying that "the United States is the greatest country that's ever existed on earth". The US has lots of quite serious problems and in saying that Musk is choosing to ignore all those problems. (And at least some of the problems the US has are caused by distinctive aspects of US culture). But, look at SpaceX – probably in no other country on earth could SpaceX exist.

Certainly I don't think anything like SpaceX could exist in Australia. Of course, the US has the advantage of 13 times more people. But, if you could imagine a country with the same population as the US but the same culture as Australia, I don't think anything like SpaceX could exist in that hypothetical country either.

If Musk's dreams come true, SpaceX could turn out to be the most important company in human history thus far. (Of course, maybe his dreams won't come true – but I hope they do – I would love to live to see the day that humanity becomes a multi-planetary species.)
The other option is it's new cases each time, and your wife just really needs to start wearing a mask, and better had washing.
There's something odd about this.

The US is said to have very high salaries in PPP terms. But at the same time, I read about extreme costs every so often. "3.2 km of tunnel […cost…] $4.45 billion. A 1.5-mile (2.4 km), $6 billion second phase […] is in planning". And about things that don't seem to coexist well with affluence, like large parts of the population being unable to go without a single month's income, or car loans at more than 100% of the purchase price and with repayment plans longer than the car's average lifetime.

Something won't fit tigether here, mentally.
Dönüşüm Oranınızı Yok Etmeyin: 16 UX Hatası – Bi Adam Medya
It's an interesting topic because I've heard a South African joke that every American has a pharmacy in their house (talking about over the counter meds in that case) so I guess it's a common perception around the world. It's funny because most Americans have the opposite view (except regarding mental health medicine for some reason), if I had to summarize the attitude it's essentially "I hate being sick and I've got shit to do".

Stoneage for sure but probably more realistic.

Anyway, in my opinion it's not a waste of money. Besides the potential scientific results which will always be interesting, manufacturing skills are evolving this way as well.

I don't know so much about SAFIRE and which state it reached, but Wendelstein 7-X and ITER are the two projects I'm confident with, and I don't see them as competitors but both bringing more knowledge about fusion.

You perhaps haven’t been reading any of the papers coming out of Europe?

In my submission history you can see just yesterday an MRI study out of Europe. 78% of patients had cardiovascular involvement, 60% of patients still had heart inflammation.

These were 100 Germans, tested 2-3 months after diagnosis. And 2/3rd of the cases in the study were mild at home cases, no hospitalization. There was no large difference in heart involvement between groups.

A fairly large amount of the literature on these effects is actually from Europe as you got hit a month before the US, so there’s been more time to write studies.

I would not say you have any evidence in support of your position. I certainly have not heard of any studies finding covid to be a multi fanged beast in america and a mere respiratory virus in the rest of the world.

Edit: the paper: https://jamanetwork.com/journals/jamacardiology/fullarticle/...

I read it: it is a real paper, professionally written in an staid tone. Therefore, even if the premise is entirely wrong, even if you disagree with every single word, there is no reason for it to be "retracted".

> If yes, why aren't we seeing more Open Source Project being built using Rust as compared to Golang?

That might be your bubble. I'm seeing a ton of new Rust projects almost every other day here on HN, some of them quite serious.

> CockroachDB however seem to be investing time working around GC pauses and FFI overhead of Golang.

Twitch.TV I heard are struggling with the GC pauses as well. Golang is far from the safe choice in any situation where you need high performance. Its advantages come with some drawbacks.

> I'm particularly curious about why new Open Source DB's are choosing Golang as opposed to Rust or even C/C++.

I spoke with several Golang devs the last several months and the answer is quite prosaic and you might not like it: Go is easy. Rust, Haskell, OCaml are hard. People almost always opt for what allows them instant productivity and never stop to consider if that doesn't mean problems down the road.

---

IMO Rust still has stuff to sort out -- I am particularly not fond of the many ways to do the same thing for example, and the compilation speed. Also the async/await thing might need some more polishing still.

But everything I've written in Rust is extremely stable and performant so far and I am sticking with it. The core team has proven themselves extremely capable, many times, and they deserve a vote of confidence.

It may not be for you or your company, but it is clearly resonating.
Though in accounting you have to be clear about what you have versus what you owe, and transactions must target the correct accounts in order to make sense, there is no need to befuddle the fundamental equation with those details. It is much clearer mathematically to have the fundamental equation be "all accounts always add to zero". That's it; no mention of their "type". Likewise, the increments/decrements in a transaction just have to add to zero.

This is the same as conservation laws in physics; e.g. integral over a closed path over a conservative field. Or the Kirchhoff voltage law (sum of voltages around an electric circuit is zero).

Debit/credit accounting is like designing a circuit in which for some silly reason we decided to mix conventional current and electron current! Oh, this is a liability resistor, so we use electron current, but this is an asset capacitor, so we use conventional current. The circuit law then doesn't add to zero, unless you remember which elements need to have their sign flipped, and you end up with strange rules like equity volages equal asset voltages minus liability voltages.

Can you imagine doing such a thing when designing a device with hundreds of parts? Yet, big ledgers can likewise have hundreds of accounts. Then a corporation needs a small army of accountants to keep a simple thing straight.

It's not just the adding to zero that is crystal clear, but the polarities of the accounts. When I see a negative balance account in the ledger, I have a good idea that it's an equity/liability account just from the balance alone. Minus means owing, plus means having: very clear.
What a classic. "You wouldn't know her, she lives in Canada." Fuckin hacker news libertarians never fail to deliver.

- documentation in the form of a GitBook guide

It's still quite early in development and feedback is very valuable.

> Speaking of letsencrypt

Let's Encrypt is a website/service. There are many clients and you can write your own.

Neither DNS nor HTTP needs to be hosted on the same host as your mail server though.

This is a completely unsupported position composed of biased, speculative nonsense. Much of the science about impacts beyond basic respiratory problems is coming from Europe, "recorded" on europeans.

It is in fact very possible to do this, a fact I found surprising. In Asimov’s biography he described having gone about his affairs for at least several weeks after a major heart attack. He thought it was indigestion I think.

This is, of course, a very bad thing for the health outcome of a patient, and it is far preferable that they get early treatment. But it is certainly quite possible to live after a heart attack.

It’s in fact a common enough phenomenon that Harvard writes articles about it: https://www.health.harvard.edu/heart-attack/when-heart-attac...

I'll definitely edit the post adding the relevant bits you mentioned.

Two special notes:

About 1. stdClass, you're right and I don't know why I just took it for granted without even testing. My Bad.

About 3. casting special types, you're right again. I didn't phrase it properly. Casting null to other types won't yield errors and casting resources too. Their values are normally nothing we should rely on, but doesn't mean one "can't" perform such casts.

Thanks a lot for your comments, they are incredibly helpful!
