> what's wrong with it turning off DND mode when your 1hr DND timer expires? What else is the point of the timer?

What I think is wrong is the default being "DND off". I mean, I wished it went back to the previous mode, which was the scheduled DND, but I understand if after the timer the device goes into "default" mode. The piece I don't get is "DND off" being the default mode, as if I was looking forward to be disturbed. Especially if this device in particular knows when I'm sleeping, and there's a mode that is pretty much "DND if I'm sleeping". Maybe I'm looking forward to getting notifications, but who thought I would also be looking forward to be awaken to get them?

> Does that smartwatch not let you toggle DND off until you decide to toggle it back on? Is there no silent mode?

Yes, the silent mode is just DND, it doesn't have sleep mode, or airplane mode, just the DND.

> But to answer your question, people generally want to be disturbed by notifications.

That might be true, and it also might be the reason for "disturb" being the default mode. It's beyond my comprehension, but it wouldn't be the first time when the general public has a different opinion than mine.

And this also brings something up. People generally want to be disturbed by notifications, and *potentially disturb anybody else in the process*. I mean, I wish I didn't have to endure all the buzzing/blinking/noise coming from devices nearby.
I will start by saying that I use Clojure at work and I have tried to get into CL in my free time but just can't get myself to commit.

> Clojure sounds like the choice to avoid because of the JVM

The JVM is most definitely a big reason you SHOULD choose Clojure over CL in my eyes. It allows access to a vast selection of existing libraries.

I'm not sure what sorts of projects you would want to do with the new language but if you plan to do web development (or mobile dev with React Native or desktop with Electron) with your choice of Lisp then Clojure allows you to do that with ClojureScript.
Ask HN: Private Repository on GitHub Leaked?
I had 2 accounts compromised last week:

1. AWS account
2. Gmail account

Both keys (account secrets for AWS and user/pw for gmail) were only used in a single repository hosted on Github, private, with only me as a collaborator. Both accounts were accessed within the same week, thus this .env is likely the source of leakage.

For this project, I only work from the same PC. If my PC was compromised, I would expect other accounts to be compromised as well.

The application server (in DigitalOcean), that also reads from this repository, has no signal of intrusion.

I know that it's a bad practice of keeping production keys on the repo, but was confident that if I was careful, it would not be easily leaked.

Am I missing something else?
Which Sennheisers? Their 25 Euro in ears broke on me as well (C25x?), but as a pupil I couldn't afford better and just burned through some of those. Time lapse to a decade later, and I got myself the HD650. They sound exceptionally while still being relatively affordable (not that this would still be an issue, but I'm not a maniac who spends all their money on audio equip) AND they can take some abuse. At least that's what long time owners report, and that's also my own limited experience after 4 years - I take care not to trip over the cable and throw them across the room, but that's about all the care they get from me. [edit: okay, and if I stuff them in a bag, I'll stuff them on top or put some clothes between them].
> sovereignty over free trade

I yet to get an actual concrete example of the sovereignty lost/gained.

Its always a high concept freedom this sovereignty that. But give me example of how EU was damaging UK interest to the point where they were loosing their sovereignty.

An please, on weasel/'technically correct' arguments. An example that affected lives and interests of British citizens. Also, UK was part of union, this doesn't me its all about 'me' its about consensus and fairness. No argument France had slightly better deal for their farmers etc.

I thought it was much better back then, you could find niche sites that were of interest.

Google seems to have banned all the interesting wild content that made the internet so fascinating in its early days. Blogs seem to have disappeared completely for instance and I have to specify the site to search to find anything e.g. site:Reddit.com

The Falcon 9 booster is going relatively slowly, so retro propulsion into the atmosphere (re-entry burn), the grid fins, and the landing burn are sufficient to land it.

Starship is intended to re-enter from orbit, which is a lot faster. Using aero braking requires much less fuel, and avoids the need for a re-entry burn which may not even be feasible.
"If two parties engage in a transaction without coercion, it must be because they are both made better off by the transaction or they would both be less happy without the transaction."

That's is about as accurate as physics homework you do in school, two objects collide without friction and air resistance, no energy is lost to sound, heat or deformation of the objects, calculate their resulting velocity.

As soon as you enter the real world and those objects are cars, equations aren't remotely accurate.

That is very nice. I wonder how could one integrate left mouse click in there and also if it would be a fun unconventional gaming controller for a tailor made game. It would have to be balanced, as one of the commenters wondered here. A graph coming from playing with it like a ball would be interesting to see.

I gather people reading this thread could have some knowledge regarding Linux/X11 input devices handling. I bought a TLK keyboard with a trackball built in and I would like to use it as a scrolling ball. But I would like for it to send events like from two finger scroll on a touchpad, that applications aware of it would scroll smoothly like on a Macbook or a Chromebook. I assume it has to do with libinput. How could I approach this? Bonus points if I could use scroll-lock key and indicator for the scrolling mode.

EDIT: I bought this one: https://perixx.com/furniture_store_view/catalog/product/view... One issue I have with it: I don't know where is the numlock key, probably something with Fn keycombo, but they did not print much on key caps.

I was a PM in a long ago prior life and, at one point, we decided to bring development managers into more customer meetings. It wasn't a bad idea but they had their "day jobs" so would end up being only in a few meetings. So it ended up as almost mirroring sales where the last customer they spoke with was taken as gospel and a blueprint for what we ought to be doing.

To one of the broader points, in both my personal experience and what I see software PMs doing in my current non-PM role, they spend a lot of time talking to customers.

Ask HN: Why are we so bad at valuing public companies?
I’m looking for clarification on my thoughts here.

The intrinsic value of a company is the net present value of all future cash flows.

Technically the share price shouldn’t change then. The behavior of seeking long term capital growth in share price appreciation implies that the companies are perpetually undervalued.

Yes, market forces are what ultimately determine the actual share price, but if the stock market worked efficiently there should be no money to make from price appreciation and the only incentive being dividend.

So if a company doesn’t pay you the prevailing interest rates for a dividend they are saying “our stock is undervalued right now” and you should expect greater dividend in the future.

This also entails that some companies that failed were actually worth zero.

But as we get better at predicting things shouldn’t this concept of capital gains through stock appreciation taper off eventually?

> Jupiter has a number of characteristics that we can observe, such as gravity, that are best described by the theory of being a planet, heavily simplified. edit and if we remove Jupiter from our theory, we have a ton of observational data that now does not fit our theory.

Sure, but isn't it the same for multiverse theories? Obviously we don't observe the multiverse directly, but we observe data for which the best explanation also implies a multiverse, just as the best explanation for various observations implies the planet Jupiter.

> Another universe, basically by definition, has no observable characteristics. We can seemingly only observe our universe, and have no way of knowing if something unobservable is impacting our universe.

There's a lot we can't observe or interact with directly; we can't interact with the past, we can't observe the future, we have to real way of interacting with distant galaxies, we can't actually observe inflation at all... a good multiverse theory (of which I'm not sure there are any, but I think they're possible in principle) would be in much the same category as inflation AFAICS: we can't observe the thing itself but we can observe things that seem most likely to be consequences of it.

> As for whether 1 dose prevents spreading: for many countries, in particular UK, the current bottleneck is hospital occupancy, and that is overwhelmingly people over 70 - something like 60% IIRC.

Preventing the spread of COVID19 has an exponential effect on all stats.

If 1-dose only reduces the symptoms (but continues the exponential spread), then 20% vaccination rate means that you have 20% fewer hospitalizations after a month.

-----------

In contrast, if 2-dose prevents the spread, then 10% vaccination means 10% fewer spread *PER GENERATION* of COVID19.

That's 90% of the hospitalizations in one generation (~1-week period). After 2-weeks, you have ~81% hospitalizations. After 3-weeks, down to 73%. After 4 weeks, only 65%.

Controlling the spread is the #1 health priority that has exponential effects. I'd take 1/2 the vaccination rate if we have a better chance at tackling the exponential-spread issue.
I spent several weeks in NW Australia, in desert areas. At this time it was considered one of the darkest places on Earth.

I can honestly say the stars were the most incredible thing imaginable. I slept in a swag, under the stars for many weeks. I’d wake up sometimes at about 2am for an hour or so as I’d go to bed so early because we had very little artificial lighting.

One particular night I remember the whole sky looked purple and white with stars, I could see so many objects moving, satellites and who knows what else, the sky looked alive.

I remember thinning how lucky I was to see it, I also remember thinking “why would anyone watch TV if they could see this instead ?”.

It really put things in perspective for me and made me realise the earth is an incredible spaceship, maybe the best one we will ever have!
> Ofcourse Narendra Momeme and his fan club owe their rise to social medias algo amplification design, as much as anything else, so its going to be interesting to see where the story goes.

Narendra Modi was 3 times Chief Minister of Gujarat much before Social Media even existed. He was already popular and a seasoned politician. And Congress being the weakest helped him a lot as well.

You can probably attribute Social Media for Arvind Kejriwal's rise to power in Delhi as a more accurate representation of Social Media having direct impact on electoral politics. But to say Modi came to power only because of Social Media is the most ignorant take on Indian Politics.
I remember my school ran a contest where you had to find obscure information on the net. Things like when the inventor of the saxophone was born? You had to submit an URL so using the library was not an option. It was insanely hard, nowadays it's just one wikipedia click away.
There's plenty of crappy science journalism out there, but odds are you're forgetting all the qualifying statements like "as early as" and "if emissions keep growing at the current rate". If you go check articles from 20 years ago I'd be willing to bet these qualifiers are in most of them.

Many people seem to mentally filter all these qualifying statements entirely.
They care a lot about advertisers and lawsuits at very minimum.

Nobody wants their video ad up against 'controversial' material.

That said, there has to be a way to redress these grievances.

Of the many things we could start to regulated it's that:

1) If there is a take-down, they have to tell you why and give you a few days to dispute or to open a grievance.

2) Grievances have to be addressed.

I don't mind even if there is a fee - it's reasonable for Google to require $100 to address a grievance, after all, they are hosting for free.

Alternatively, they could be required to have a 'paid version' without ads in which the bar for issues was considerably higher.

That's just off the of my head, so not exactly well thought out.

The point is, however, they're reaching a scale whereby some of these platforms are equivalent to a public good. It's like they are becoming broadcast or telecoms, which were always subject to regulation.

Yeah I think it could be along the same lines. That even in our ultimate mental state, you still don't have the capacity to capture the reality of every moment. Our abstractions are how we see life, and they're just abstractions. The psi is doing something to cut those away, which can be beneficial for people who are caught on something (depression, ptsd, etc). It can be bad for some, who blend that raw perception into their lives and "cant be normal" anymore.
So adding a border between NI and Great Britain is pissing off the people who see it as creating a big separation between the 2 parts of the country known as the UK.

Okay, that helped. The goods in question were shipped from the island of Great Britain to ports in Northern Ireland.

But what also confused me was from the article itself, which said "Mid and East Antrim borough council agreed on Monday night to remove 12 of its staff". The word borough implies to me some sort of local government, like a city.

So why is a borough council responsible for border checks?

In the USA if something arrives into, e.g. the Port of New York and New Jersey, it is the US Federal government that is responsible for checks, not some local government.

The port is a port of entry. The United States Customs and Border Protection (CBP) and Immigration and Customs Enforcement (ICE) regulate international imports and passenger arrivals.

I really wish the Racket team would write a book on Racket’s language making capabilities, or create a MOOC. I attended Racket School 2019, and it was awesome. The material was well put together and walked us through macros to #langs.

I have many ideas for little DSLs in Racket, but I am too slow and am slogging my way through learning how to create them.

Honest question: Have you worked with fluid simulations before?

We cannot fully predict turbulent flow from first principles. I mean, we can, but when constrained by real-world computing hardware, we can only do it in very tiny domains. Turbulence requires way too many orders of magnitude in spatial resolution to fully resolve it in "real world" problems.

Therefore, any practical simulation for engineering purposes involves some way of modelling (read: approximating) turbulent behavior at sub-grid scales. There are tons of these models suitable for all kinds of different applications, domains, flows, etc. - but they are all just models. Part of the engineering effort is finding the right model for the task on hand, and for that you need experimental data.

This of course doesn't apply only to fluid dynamics (but also e.g. the overall dynamic behavior of the entire assembled rocket and rocket engine, which could interact with the fluid flows in a nontrivial manner), but the point is that simulations aren't automatically accurate because you do more of them or throw more money or compute at them (that is also a good way to burn cash) - they are still approximations of unknown accuracy until you actually compare them with data from reality to confirm whatever modeling assumptions you made. The "least cash expenditure" approach will thus involve both simulations and experiments, and you will eventually reach the point where putting money into making rockets (potentially) crash will give you better lessons than running yet another simulation with (unbeknownst to you) subtly flawed assumptions.
> Phones are noisy, and phones are distracting: how often do you need to quickly check the weather and instead you read your notifications? Keeping it in airplane mode at night is a big life improvement.

Agreed. Phones are noise and distracting. But those are not intrinsic qualities of phones. We have made phones that way, and we can made them any other way we want.

Other people talk about airplane mode. I kind of like it but I'd rather not be disturbed by default, so that wouldn't be necessary.

I'm around the same YoE but some things that I've felt have accelerated my growth:

- build things outside of your comfort zone

- work with smarter people than you

- be intentional about your work. Always have a theme of something you want to improve

And the biggest one:

- Choose to be an excellent developer.

Mindset is important. If you tell yourself you're an above average developer, you're more likely to improve your craft because it's part of your identity.
