I had the same thought but...

The smear technique results in seconds that are 11.6μs longer than nominal, and Google makes the case this is within the "manufacturing and thermal errors of most machines' quartz oscillators". So at face value, I'd say software already copes with discrepancies of that order.

However I would infer the maximum delta actually seen by an NTP client is larger and depends on the client's polling interval. e.g. If a machine runs a normal clock locally and synchronizes every 20 minutes (which is probably on the high side), it would see about a 14ms jump on each sync during the 24 hour smear window.

That's assuming the NTP client doesn't already use a smear algorithm locally to correct for drift (Windows doesn't, but I think Red Hat Linux might? Per https://access.redhat.com/solutions/39194 "NTP polling does not directly synchronize the local system clock to the server clock; rather, a complex algorithm calculates an adjustment value for each tick of the local system clock")

Maybe someone more well-versed can elaborate further.
It's the same in Greek, Monday means "Second" but still, everybody considers it the first day of the week.
Well no, because for these cases the most important thing that a blockchain solves needs not be solved.

PoS (or PoW) are not needed because there is no sybil attack nor a byzantine-general problem to be solved. In fact, most "Private Blockchains" ditch the PoW and therefore can claim "tremendous scaling" or things like that.

Ditching the PoW solves most of the scaling issues. Sure.

But a blockchain without a PoW is simply a log that is cryptographically signed (but not secured). Because I could very easily just change block #2 and simply accept the cascading effect. People familiar with Git use this principle every day. A git --amend and git push --force is exactly this.

Once you can convince the participants in your private network (your colleagues) to use your branch, history has been rewritten. (And the old work is just one garbage-collection away from being forgotten forever).

So, yes, it is very much a definition question. But that is because "a blockchain" has it's requirements and its pro's and cons built into that definition. So if you start stretching the definition, you simply loose requirements. And you end up with something that really makes no sense.

If you read the definition of blockchain by Nakamoto in the post, the most important point of a blockchain is to provably keep track of the order of the transactions.

Ask HN: Why US tech companies asking for work permits from remote freelancers?
US remote positions usually got requirement "Eligible to work in the United States".

Is this related to mindset, or there are some regulations blocking overseas freelancers to do remote jobs for US companies?
> As a person authorizing a product that can potentially emit unhealthy or unsafe levels of RF, or a parent of teenagers using social media, or a developer of medical applications intended for mobile phone... I am none of that, but I guess I would have a very different opinion.

Let's be honest and accept it's just about money and control to the makers of these devices. They will bring reasons such as these in their defense, but really they just want to keep the user from being in control of their device and e.g. making tracking them more difficult. I mean there have probably been tens of thousands of roms flashed on different devices. How many of them have emitted unhealthy levels of RF? And parents could retain the ability to flash their devices without giving that ability to their children. The reasons really just don't hold any water imo.

Following the population explosion of mosquitoes.
This simple isn’t true - Apple made an app that lets you call arbitrary links and display the result, and in a gallery added one example for guitar chords linking to this site. The gallery also has examples for third party integrations for news, weather, music, bookmarking and it’s not unreasonable to expect more for lyrics, laundry, taxis, groceries or pretty much anything else.

This site was in the examples for guitar chords, that’s about it. Maybe they should have asked him, but there’s zero obligation to do so. If you have a blog someone links to it, you don’t mind, do you?

The point of contention here is that the template linked straight into the chord image generator - which isn’t kosher. If I build a chart generator for my site, I wouldn’t want anyone linking straight into it - Apple isn’t using it on their site and claiming it’s theirs, but they’re pointing out to all their customers that they could just hit my generator directly for visualising charts. That’s weird. Not illegal, but weird.
This was a response to test coverage used as a benchmark. I see them both as an indirect project quality benchmark.

Sure, others will disagree - but the whole idea of quality in this context is subjective anyway.

The original usability win of the web was that anyone could put up some text with pictures and links and anyone else could see it. It was proto-Facebook. I think of the evolution of the web as a sequence of technologically trivial but socially innovative changes in format: from static pages to timestamped blog posts, aggregating multiple blogs in a feed, allowing comments and so on. That's the vision laid out in Clay Shirky's writings about social software, as true today as ever before. And unlike the "semantic web", that vision naturally leads to a wealth of semantic information (like friend graphs) which is tremendously useful.

Hopefully that explains why "API primitives exposed to webassembly" feels to me like thinking about the web from the wrong end. The social end is what makes the web tick. It could be built with tinkertoys for all I care.

> How about non-approved images pumping power upstream above regulatory limit on RF?

This is possible through other means (you can buy RF chips and wreck havoc on the frequencies). And it's illegal to do so anyway.

>Or overclocking the CPU? Or reporting all keystrokes to a place of your choice?

I, the owner of the device, might want to do this and these are sometimes completely reasonable things to do (if you're a developer, for instance).

> Would you, as a manufacturer of the device, like to make that easily possible?

Probably not, but that goes against the interests of the customer. ("but most of them won't care anyways")

> What makes it impossible is not the secure boot but the fact that the _unauthorized_ 3rd parties don't have the keys for signing stages of the images.

I am completely fine with this if, and only if, I can add my own secure boot keys and sign my own firmwares/OS images which allow.

I, the owner of the device, should be an "authorized" party when it comes to my device.

I am willing to accept that I do not get 8k service from YouFlix Inc if I add my own keys.

I have no problem with secure boot (the technology) but I do take issue when it is used to limit the rights of the owner to their own device.

I sympathise with the consumer associations: charging for largish hand luggage makes price comparisons deceptive, distorting the market.

On the other hand, storing hand luggage overhead is one of the most time consuming parts of the boarding process, which is even worse with Ryanair's short intereuropean flights. All that time spent on hand luggage costs money, and it seems only fair to make those pay that cause the delay, incentivizing people to take less luggage (bags that can be stored under your seat are still free). It makes economic sense for everyone.

To satisfy both sides of the argument, you could show the price with large hand luggage fee included, and offer a discount if you show up without hand luggage. If you extend that concept, you arrive at a "base feature set" that has to be included in the base price of any flight, and from there you can add surcharges and discounts.

Why not charging by passenger weight then?
Firstly, travelers are consenting adults that should understand and accept the baggage policy - or use a different airline. The market is extremely competitive.

Secondly, as a person who has traveled backpack for years, I find the whole "luggage is an essential element of air transport" line quite offensive. It's a service I want to purchase but you won't let me because some guy might be confused by a price comparison app to buy a baggage-less ticket (mind you, not even by Ryanair themselves, on their website it is very clear what you get for the price). It's revolting.
For most companies, securing funding and getting exposure in the media is significantly more important than using technically correct terminology to describe the implementation details of their product.
I took a fairly short Ryanair flight recently, and it was much nicer with these new baggage rules.

No-one was rushing to board first, in order to fit their sized-to-the-limit suitcase into an overhead locker. There was plenty of room left for handbags, small backpacks and so on, so those (like me) who'd paid for checked luggage didn't have to have their small bag around their feet. Boarding was noticeably faster.

These were my biggest annoyances before.
A homeless person in a civilized country has access to a lot more than the actual cash represented by that $1.90. Many times they have access to free water, food, shelter, even medical care. These could be worth hundreds normally.

If I build a chart generator for use in one of my sites, hosted on that domain, with no published API whatsoever, it would be odd to see some random productivity app using that straight from peoples phones to chart their stuff.

Not illegal, Apple or the developer isn’t claiming that my API is theirs. And maybe it’s open on my robots.txt and maybe my terms of service say nothing about it.

But it’s weird. You just pushed an app out to a billion devices allows users to hit my chart generator directly. That’s plain weird.
Perhaps it's not, but it is a bit more compact and even more so in my native language, Swedish. The names of months are longer: "September", which is the same word in Swedish has four syllables while the word for week ("vecka") has two.

And sometimes you really want to speak about the entire week without naming a day ("we'll have the first boards week 40, smoke-test and bring-up during week 41, and then start proper development by week 42"), since it's times in the future and you don't want to be too specific but still align work tasks with weeks.

Also (re: a sibling comment) Google Calendar shows week numbers, or can be configured to. For quickly finding out the week number, there's always https://vecka.nu. :)

This is just infrastructure (as it should be), right now the middlemen are very expensive because of all the paper documents going between companies, and all the people hired to go over all of them. The usual arguments for these projects are:

- Cheaper

- Quicker decision making & communication

- Less fraud & errors

For us consumers that would probably result in cheaper apples in the the grocery store I guess.

Would there be a difference, if Apple had downloaded the content and was serving it from its own hosts? (As far as an app user is concerned, there isn't much of a difference.) Now add to this the hosting fees / resources used…
Thanks for your summary. Indeed it is very hard to explain these ideas, because so many terms are still vague, missing or explained in often contraditing ways.

I think, indeed, that with "permanence" i've made the mistake to pull that together with "immutability". My first draft had them as different points, but I found that this made the explanation too complex. So I decided to go only for "immutability" and to move the "permanence" under there.

In your definition of permanence (the correct one, BTW) this is not the same. Permanence needs economic incentives. As we can see with IPFS (and it not -yet- being permanent in practice). Immutability, however, needs (i) cryptography and (ii) conflict resolution and (iii) permanence. Which implies "being public". As I tried to explain.

Or did I misunderstand your comment, and do you mean immutability as well as permanence?

With the launch of services like Robinhood, access to investment in the public markets has never been easier. If you are currently investing in anything (stocks, funds, bonds, crowdfunding, other alternative asset classes) on the public markets, can you please describe how you manage and keep track of your investments?

I am less interested in budgeting tools and spend tracking, and more in wealth and investment return tracking (portfolio tracking).
Also - less interested in professional investment and more in consumer tools (so no professional venture capital or seed investors or day traders who do this for a living please)

- the intermediary you use (broker, platform, app) to do your investment.
- the tools you use to track them (provided by the intermediary or third-party)
- where you live

Context: I live in London and I find none of the tools available (at least in the UK) are comprehensive enough, so my portfolio is fragmented and I have no single view of how it is performing (unless I use my own spreadsheet). Thank you for your responses!
