Contact tracing was and is a major part of the response in Canada. We have similar fines and penalties. Quarantine Act emergency measures are in effect. Thousands have been fined. A handful of wilful breakers of ordered quarantine have been criminally charged.

The drastic difference in outcome so far compared to Australia boils down to just a few differences, as far as I can tell:

* we never truly closed the border. We should probably have tried harder, but it is impossible to strictly do so with the USA, at least. The majority of cases in last March and April were from American visitors, and locals who had travelled there. Those seeds of outbreak seem to still be the main strain circulating now.

* our lockdowns were not quite as strict, or strictly enforced, and were more haphazard for when they were applied and when they were loosened

* testing was not deployed as rapidly or widely

* contact tracing becomes less and less feasible with the more cases there are, and past a tipping point it becomes hopeless to expect it will actually contain it (though they certainly still try)

Cash is generally better than its equivalent worth in RSUs. If Amazon faces fiscal troubles, then you can potentially both lose your job and your retirement plan. The upside of potentially becoming a millionaire doesn't make up for this.

The problem is that a lot of people will spend their surplus cash on more consumer goods rather than rather than investing it their 401ks.
Ask HN: Comment downvoted within posting delay?
Do you have a nonzero comment delay (minutes before your comment appears) configured?

Have you seen a comment get downvoted to 0 well within this period? E.g. comment delay of 10 minutes, comment goes to 0 while you're editing it, less than a minute old.
That's exactly why I think it could have saved us from the one-eyed worldview of media powers. Just weed through the forest and work your brain to collect 'information'.
No. They literally were talking about 15% of $100k being sufficient. Re-read it.
I think this thread is much about shared source licenses like SSPL vs. "orthodox" open source licenses like GPL.

Based on the link below it seems to me the difference is that SSPL etc. have a clause which prevents me from making money by selling the use of the licensed software over the network for instance.

GPL puts some rather strict rules on users of copyleft software, mainly that you MUST distribute your modifications with the same license.

What I don't quite get is why adding a rule that says "if you make this software usable over the network you must make it usable for free" would be considered categorically less ethical than GPL.

GPL says you must give out your modifications for free.
SSPL says you must also give out the rights to use that software for free as well.

Isn't SSPL more ethical in the sense that it requires you to give out more for free?

I suppose that's a fair criticism, but it seems tangential to the central point that Israel and Saudi Arabia play up their animosity for the public.

I would say that it's two simple factors:

1. High bandwidth charges are an effective form of lock-in. Once your data is there, it's prohibitive to move it out again.

2. Bandwidth use is very poorly understood in many businesses, compared with simpler metrics like storage, memory, and CPU. AWS can run razor-thin margins on things that people easily compare to on-prem or VPS-style offerings, and then make the money back in areas like network traffic, fine-grained monitoring, and other items that as less obvious.

Are you saying that the U.S. middle class starts at $163/326k of taxable income?
Honestly the bottom down-voted comment has it right. What AI application is actually driving demand here? What can't be accomplished now (or with reasonable expenditures) that can be accomplished by this one CPU that will be released in 2 yrs? What AI applications will need this 2 yrs from now that don't need it now?

I understand the here-and-now AI applications. But this is smelling more like Big AI Hype than Big AI need.
Wouldn't the olfactory bundle above your nose be a number of times larger than an entire rat's brain? Not to mention everything downstream of it ...

A lot of the smell sensitivity comes from ("carefully tuned?") positive feedback loops int the olfactory systems which amplify small signals.

Or something like that, supposedly. Not my area. At least, not the input side. On the output side of stink, I'm no theorist either; maker, for sure, though!
>Intervene on the basis of an online threat. If he gets punished at all, it will probably be very light. Not punitive enough.

This has nothing to do with it not being "punitive enough". If every online threat of this caliber was to be investigated and every person making those threats would get a "light" punishment, then we run into two issues.

First, there simply won't be enough resources. If you look at twitter for the majority of last year, you will find straight up tons of people who made "threats" of a similar magnitude. It would be a giant waste of resources too, given that most of those people are just venting with no actionable plans or ways to make those "threats" materialize. Not even mentioning that we might not want to stick that many random people who just talked vague "threats" online with criminal charges.

Second, those who actually were going to follow through on those threats wouldn't be deterred by "light" punishment that a vague online "threat" like that would carry with it. They would just bs the officer and assure them that everything was good, and the officer would go on their merry way. After all, if there is no proof that the suspect actually has a way of making that threat materialize or has a proven serious intent, there is not much the officer can do at this point. With that approach, you essentially tip off the suspect that they are being watched and suspected, so it would just alert them to be sneakier about materializing their plan.
I was going to say that identity is useful when replying to a comment on HN :) but you're right that the comment text could stand alone. The poster's identity is only needed for karma sorting and greylisting of comments.
The only problem here is that you have to do this in the first place. This problem has been solved some 60 years ago with Lisp and `cond` construct, which is even older than `if/else if/else`! Alas, our industry likes to forget history.

That said, this isn't some kind of high-level hackery. If it's cleaner than if/else if chain, you should use it.

Programming is a profession. A professional is expected to learn and grow. The right answer to seeing a code construct one doesn't understand isn't throwing hands up in the air, but spending the few minutes necessary to figure out what it does.
Threads Considered Harmful – ACCU 2021
Because you aren’t surrounded by peers. Some of us have lived in other areas and don’t want to go back for good reasons. People in other areas have jobs. People in SV have careers. Many more reasons to list. Average education among my peers is obscenely high (a bachelors is seen as being undereducated - masters is average with PhD being very common).

The area isn’t that bad except for COL. Once you’re rich, it isn’t that bad. So, just get rich. That’s the basics of it. It sucks but at least there is a solution for those that are ambitious enough. Can’t fix bad weather or jobs.
As usual, the problem is that Sh & co. use in-band control, especially when talking to utilities. Just a mess of text being passed around, of which every program must make sense on its own—but this happening in shell's own functions takes the cake.

Moreover, similar problems are inherited by some programs that try to do shell-like commands but put their own syntax in the way. E.g. Ansible, where YAML, JSON, module call DSL and Jinja are all mixed on top of the commands so you can bump into any of them.
```
switch (true) {
case 1 + 1 === 2:

This is wrong, Since there is no return or break default will also be executed.
I wonder whether a modern byte-sized instruction encoding would sort of look like Unicode, where every byte is self synchronizing... I guess it can be even weaker than that, probably only every second or fourth byte needs to synchronize.
Not saying it has never happened but it is illegal for the police to entice someone into committing a crime they otherwise wouldn't have committed.

This is called "entrapment" and if caught, law enforcement will face penalties for doing it, and the defendant can't be convicted for the crime.
Python almost managed to blow itself up over the move to 3, though, in a very similar manner to the 5-6 transition for Perl. It was only through a lot of hard work that disaster was averted.

That's not programmable today, but may be in the future.

Presumably the shipment has a series of checkpoints, which add some amount of traceability. There's also the potential for insurance for blockchain contracts.

I only recently learned about oracles, but I suspect we're only getting started on unlocking the potential of blockchain.

If there are oracles making the progress at each checkpoint along the way available from the blockchain, and insurance contracts for potential disruptions at each stage, your contract can ensure payment on delivery, and the supplier can be insured against any disruptions.
machine readable can involve more than visible spectrum. Radar and light beam reflectors, non-vis spectrum strobes, radio beacons, swarm. Volvo was working on this years back, before "autonomous" - cars sharing data via wireless comms, using installed navigation markers by roads and more. There are ways, just no central will.

Google, among others, is using private (external, not owned or controlled by google) wi-fi access points as radio beacons for navigation today. Good old wardriving google. This is one factor facilitating navigation in cities when GPS is spotty.
And then you have cell towers.

Centralized, standardized navigation facilitation solutions would be better, more reliable, not require mobile internet access for alignment with beacons, as they would be in a stored database in the vehicle, etc.
Interesting. I couldn't find any documentation for how this happens (does it need compiler/linker support to know whether free is used?), but I did find the source code for this __simple_malloc: https://git.musl-libc.org/cgit/musl/tree/src/malloc/lite_mal...
The other answers give cutting-edge workarounds.

Historically, the ancestor of Linux was developed in an environment where terminal standardization usually stripped out the marketable graphics features.
Sound was single beeps, vocalized with ^G.

If it seems overdue to standardize a real-time character-encoded graphics protocol, you can look at the Tektronix 4104 and descendants.

That being said, typesetting was important early in UNIX. Even though the interface was command-line, UNIX implemented roff and maybe wouldn’t have succeeded if it couldn’t word-process into roff. Word processing was the first application for UNIX outside of the Labs.

And what are some example use cases you can do with those things, or that people are using them for? Genuinely asking. I see people very excited about things like DAOs, but most descriptions seem to be about inter crypto use cases.

With the early internet it was easy enough to see there were use cases like “instantly send a letter to someone across the world” or “order a book not stocked at your local store” or “go directly to Nintendo’s website and read their info”. I remember doing this last one as a kid in the library and was instantly taken with the internet.

What are some similar ELI5 use cases of the Ethereum chain and those names you mention? Other than intra crypto loans, derivatives etc

Um...? I was hoping to get some clarification that your account is legit and some references to opinions from the broader research community for your big claims. I came here with an open mind and would have liked to learn something since CS is my passion for decades now.

Unfortunately, by reading your comment history, I learned that you've been self promoting here for quite a while and have always been ignoring questions about references to other people's thoughts on your work. I also learned that there is a wikipedia talk page and apparently the same pattern happened there 5-6 years ago, where you were asked about citations and could only come with self-citation and claims of harrassment. And after sockpuppet edits you got banned there. That's sad, for everybody.

It would be so easy for you to just throw a handful of citations into the mix and let the research speak for itself! You want to go down in CS history as somebody having discovered something big, right? I'd love to see that! Then I could tell my grandkids that I was sitting in the front row! But you won't convince anybody by only doing self-promotion and complaining about "personal attacks". Scientific progress works by convincing the scientific community, and for that you need to engage with it positively.

If that if/else chain is returning a value, then what's even more clear is:

if (condition1) {
return something;
}
if (condition2) {
return otherStuff;
}
return finally;

I don't remember the last time I wrote an if/else chain that wasn't in return position.

Ask HN: Is this a thing? Config-driven monolithic front ends?
I'm trying to research different approaches to very complex frontends, but I can't seem to find the right search terms for one in particular. I'll do my best to describe it here in the hopes that someone can point me in the right direction, and as a bonus anyone who has experience with this type of architecture can share tips/warnings.

I'm designing a web application that sits on top of disparate workflows as a cohesion layer, making them feel more like a single product. Think aggregation functionality like notification center, search, dashboarding, help, etc.

The problem I'm trying to solve is how to build something flexible enough to support the different teams' workflows while protecting a consistent user experience. I'm hesitant to invest in a micro-frontend approach like single-spa or web components, but I don't think a monolithic approach has any hope of scaling (e.g. a single frontend team that has to understand and interact with dozens of different domains / services / workflows will become a painful bottleneck). One possible middle ground would be (for lack of a better term) a 'config-driven monilith': where a single team owns a few core experiences (landing page, dashboards, search, etc) and teams integrate by 'configuring' them through the use of control/data-plane APIs.

To give an example: for a dashboard, each team configures the expected data shape and e.g. importance (constrained by the control plane APIs), and then pushes data for users following that schema. The core team would own rendering the dashboard based on the config and pushed data. We could discuss the trade-offs of push/pull, but the point is each team isn't left to its own devices on UX, and the core team doesn't have to become experts in each domain. This is the simplest example I could think of, things obviously get more complex for data capture/forms.

Is there a name for this approach to building a complex frontend? Any examples out there?

I don't trust anybody's ability to predict the future. The economy typically runs on a roughly 10 year cycle, but wars, pandemics, and natural events can throw it off. The stimulus will probably work for a while, but can't last forever. How long it lasts and what happens afterward is hard to say.

It's called private life for a reason: it's not in public.

But when acting as a public speaker and spokeperson you should be acting accordingly.

Weird remarks about age of consent on public mailing lists, or hitting on every young woman at a conference or eating skin from a foot in front of a whole audience are all behaviors that put the whole FOSS movement in a bad light.
Elixir.

Yes, most of you have heard of it, but I think it is still very underrated.

Especially interesting is the ML libraries that have come out recently and OTP24 whose new JIT compiler gives a ~2x speed improvement to Elixir code, depending on the task.
Same thing that happens to humans. You see parts of the signage. Or none of it, and drive on memory (and follow the behavior of other cars).

The idea behind adding special markings for computers is that you can waste a lot of time and effort trying to perfect algorithms interpreting signage optimized for human consumption, or... you can spend much less time and effort, to much better effect, setting up additional signage that's easy for computers to consume and provides information relevant to computers (which is not necessarily the same as what humans need).

Note that roads are controlled, artificial environments. There's always someone responsible for maintaining a road and signage on it. The infrastructure to deploy additional markings dedicated to self-driving cars already exist.

I understand Twitter is already accessible to African users, and this blog post is about expanding Twitter's employment presence in Africa. That said, I really don't want to see Twitter or other Western technology companies extend their tentacles further into Asia or Africa. The immense influence these Silicon Valley companies have in shaping public conversation and culture threatens all other cultures and diversity of thought globally. The adoption of Twitter amounts to digital colonization, a vehicle for cultural globalization that homogenizes societies in the shape of American progressive culture.

I really find Twitter's blog post to be deceptive and tone deaf. For example consider this:

> As a champion for democracy, Ghana is a supporter of free speech, online freedom, and the Open Internet, of which Twitter is also an advocate.

Twitter heavily censors moderates and conservatives in America on any controversial topic that is current - whether that is COVID-19, or gender identity, or immigration, or whatever else. Africa is a lot more conservative than Silicon Valley and holds very different viewpoints on life, morality, ethics, law, politics, etc. Is Twitter going to censor African users and steer their speech as well? If so how can it possibly claim to be an advocate for free speech at all?

Another problematic statement:

> We still have much to learn but we are excited to listen, learn, and engage. Public conversation is essential to solving problems, building shared ideas, and pushing us all forward together.

When has Twitter ever listened to those who think differently from its employee base? I don't think Twitter has listened or learned at all, even in the US where it is reasonable to expect that they would understand their user base better and cater to all viewpoints better. Instead, their playbook seems to be to impose the worldview of their employees and vocal activists on the entire planet. Whether intended or not, the effect of Twitter's adoption in other nations is propagandist, and I find it to be as repulsive as physical colonization.

I hope users in Africa are alert enough to realize that they should use a local platform, or at least one that is more honestly in favor of free speech, rather than one originating from Silicon Valley. European leaders are already waking up to the existential threat Western influence poses to their culture (https://www.nytimes.com/2021/02/09/world/europe/france-threa...), and China was of course well ahead of other nations in seeing the threat of cultural erasure coming from America. Africa, a continent on the rise and on a path towards global prominence, should be similarly wise.
You're a successful machinist/plumber/accountant/chiropractor/electrician/IT specialist/etc with a couple decades under your belt working for other people. In decades past you'd strike out on your own.

In 2021 you look at the regulatory environment and overhead costs of starting a business, say "screw that" pick it up as a side gig and find a day job where you can coast. Maybe if you have some special love for the IRS you make an LLC and call yourself a consultant.

This change has affected both the blue collar trades and a growing share of white collar professions these days. The larger of a headache it is to be Real Business(TM) the larger the potential upside needed to justify it. Unless you think your ideas are gonna change your industry or you plan to become the regionally dominant player in your niche why start a real business when a cash only side gig will scratch that itch most of the time?
A not-anti-capitalist socialist is not a socialist. TLDR: Capitalism is when production is determined by people holding capital. Socialism is when production is determined by the members of society. So the question being, should an economy be democratic or run by the rich.So long as socialists workers work democratically, there is no hypocrisy in earning money.
