Had Workplace in my last job, just started a new one which uses Slack.

I do not in any shape or form miss Workplace. It was sucking my attention dry, blocking meant I'd lose out on things that actually matter.

With Slack it's super easy to set notifications to null except for eg mentions or important groups - and can even have different defaults for mobile vs desktop.
The main step seems to be Lemma 2. The fact that the reductions are logspace is never actually used in the argument - so if this proof worked, it would also apply to arbitrary reductions, and the same argument would show that NP is not contained in, say, EXP.

The fact that there are no inequalities anywhere throughout the paper is the real tip-off that this is not a serious attempt.
>The stock market is not zero sum

All securities are held by someone and the total return of the market is the total return of all those securities. For someone to outperform the market he has to hold a mix of securities that outperforms and whoever holds the opposite mix underperforms. Sock market returns are very much zero sum.

>the other side of well managed hedge funds are usually poorly managed pension funds/hedge funds

How do you pick ones from the others?

>index fund ETFs that blindly buy a bunch of stocks without looking over their financial statements

That's the point of those ETFs, replicate the index exactly. If they're replicating the market average then they're doing exactly their jobs.
I am very surprised given how little machine gun barrels resemble a motar round!

Yes,

On that note, sure my son's girlfriend's parent seemed okay with her dating a Black kid. But when he dropped her off to our house for the first time, coming into our neighborhood of new houses where on the entry way it says "houses starting at $X" where $X denotes that we were probably upper income, and from my sons mannerism and speech you could tell that he grew up in the "right part of town".

Would he be okay if my son was the same kid but we lived in a poorer part of town? Probably not.

> Focusing on the total GDP and intentionally downplaying China's extremely poor per capita figure is not even politically correct - what can be individually achieved & enjoyed by those 1.4 billion regular Chinese are clearly far more important than a meaningless national GDP figure.

Depends what you're evaluating. If you're evaluating standard of living, yes. If OTOH you're evaluating the power potential of a country's government, then total GDP is more important than GDP/capita.

> One thing I feel very funny is the entitlement, such as one from this article, that US is destined to be NO.1 in anything that is phrased as race/competition, is rarely being questioned.

For much of the 20th century, and certainly from 1945, USA was #1. If wanting to stay that way helps them to up their game (which certainly needs upping, politically), then good luck to them.
As an interesting aside, when the term "meritocracy" was created, it was a pejorative; something we should seek to avoid.
You need to be VERY careful using Google Analytics as a backend. After a certain threshold, they start sampling your data, and results will therefore become highly inaccurate.

Disclaimer: I also created an A/B test open-source framework with Google Analytics as (one potential) backend, but then realized it's sub-optimal. I wrote about it on [0].

I found that to be a problem of organizational culture, not of chat itself. In my experience, if it was culturally fine to interrupt other people's work, quick answers were expected via chat, too. If it was the organization's culture to let people work without unscheduled interruptions, that extended to the expectations around chat, too.
There are no open source alternatives for the wysiwyg editor part of optimizely. But before you roll your own backend implementation have a look at https://facebook.github.io/planout/ .

Is there a good reason that people don’t use curved traces anymore, except that it easier for CAD software?

When traces where done by hand, they used to be curved and flowing, and frequently looked very elegant. And occasionally you see a super high speed design that’s a bit curvy today.

You'll have to remember multiple UUIDs, one per service. Now that I think of it will be rather cumbersome. And bio data has to be editable if it will be usable at all i.e. add/delete new entries - fingers, eyes etc. Damn, it is harder than it seems. Anyway, bio data as a login should be implemented, we only need to think exactly how.
This seems to me like an incredibly good example, and I've no idea why people would be downvoting it. The GP programming / technical examples are potentially easier for the reader to think "well sometimes I'd want to break that rule because X", whereas this example makes it obvious, and brings up "setting yourself up to succeed".

Ask HN: CI/CD on AWS lambda like thing
So, I envision a flow similar to using AWS S3 like service for a repository, where we are billed based on storage/bandwidth/requests.

Then we'll have a lambda-like service which automatically pulls stuff from a repo, runs tests in the cloud. We set a concurrency limit and service works as is.

Is there any company which offers similar flow? I've googled but found Jenkins and stuff like that which are big apps and not smth simple.

You only need unique passwords and a username.

Having a botnet guessing the random "kitten4" password for a random user account, is as likely as having your purse stolen for the passwords on that note. FWIW "m" is almost a secure password on a root account with an SSH that allows password authentication, even if you allow brute force attacks. Imperically speaking, obvisouly it's going to fail in the end but I hope you get my drift.
The point is you'd never have such a case, the prosecutors would never bring a case that was so easy for the defence to torpedo.

SoK: Consensus in the age of blockchains
my slack strategies lately:

* mute everything, except my team's chat;

* turn off the "is typing" feedback;

* use the web version in a standalone browser (eats 200mb ram only instead of 2+gb, in srware iron at least);

* mute colors with custom "theme";

* turn off emoji display (falls back to :foo: :bar:);

* remove the rest of the emojis with greasemonkey extension (and mute more colors);

* collapse documents by default (really helps with big animated gifs).

But I still am trying to cope with some of the problems mentioned in the article and sometimes I have this feeling that I'm part of the problem (expecting fast replies, whining at times, not being constructive enough etc).
> I think people desperately want a bipolar world, because the unipolar reality bores them. Hence their eagerness to crown China a "superpower".

I desperately want the West to win because it's the best hope for a good society, worldwide. China is a threat to that because China is (1) an autocracy, (2) competently governed, and (3) big.

If China wins, the future might be an eternal dictatorship more all-encompassing than anything we've seen in the past.
I'm not a Haskell developer nor Nix user, but I find Docker is surprisingly convenient, if only for its immutable layers file & build system: as I test different packages, I only pay for what's changed or removed, not the full setup. For example, for a C library, you might start with

RUN apt install -y build-essential
RUN apt install -y libopenssl-dev
RUN cd src && ./configure

but if libopenssl-dev is the wrong package, change that line, and rebuild, and the build-essential installation isn't redone, only what's change and subsequent lines.

Any sort of snapshotting at file system level (e.g. ZFS) would do the job as well, but Docker puts it together in a convenient way.

I guess Nix is better by using a DAG, but it's probably more complicated and harder the reason about (at least for those of us lacking in headspace).
Most of the ones I've had have been pretty much stock Android. Some weird exceptions.
If you're going to do that then only do it for email addresses where you understand the local MTA conventions (like gmail). Do not do it for domains you don't know (because you cannot predict how they work).

For instance, on my email domain, david+abc@example.com, david.def@example.com, and david_ghi@example.com are all the same ('+', '.' and '_' all act like you'd expect '+' to), but david+xyz@example.com is not (it get's picked off and aliased somewhere else). Applying gmail conventions to other domains is silly and wrong.

power potential of a country's government? what is the point of having/backing it when regular citizens couldn't have a fair share of that power?

telling 1.4 billion Chinese to work their ass off for the next 3-4 years so China's GDP per capita figure can reach 20% of today's US GDP per capita is not impressive at any level. it is a solid proof that China is still damn poor after 40 years of economic reform.

there is no competition whatsoever - when Japan challenged America's economy in the early 80s, the GDP per capita figure of Japan was on par with the American one. We are now talking about an economy that is working day & night trying to reach 20% of America's GDP per capita.

I guess is cultural, maybe people dont need microwave popcorn or a banana at midnight!

Having grown up in a rather small city and moved to bigger cities later on, I found it kind of funny how people go almost religously to the 7eleven to buy late night nuts and a can of coke (or something else). When I lived in Japan even sad... you have convenience stores everywhere, and people just go there because they get trapped in a habbit of buying a "melon bread" and a "vitamin drink" on the way back home daily fully replacing a real dinner

I think convenience stores create a need rather than solving something en many cases... they just sell junk food that make people addicted to come back again and again to get those flavors...

You may have tried this / it may not help. We have dedicated help channels - a company-wide 'help' (for anything, but normally related to technical issues or looking for general advice on a topic where you don't know who could help), and product / team-specific help channels. There's no need to @here those channels, because there's already the intermediate-level flag of "this channel has new messages, meaning someone needs help" without going all all the way to "notify everyone".

There are enough people around that someone will take a look at the channel in the near future, and they can either answer or point you to a good person to ask, at which point you're back to non-slack-specific style comms i.e. "I want to contact person X, I can either interupt them or send them some async comms".

I probably get 1 or 0 notifications a day from channels as opposed to DMs - there's just no need to @here if you have specific channels for certain types of request.

> Have you ever considered that verbally spelling something out may be a sign of a problem? If you were taking someone's credit card number, would you have them go one digit at a time over the phone, then read it back to them and so on, or email it so you can copy and paste it? Or how about just have them autofill a form?

I don’t use CCs, but I (and my parents) have memorized the Kontonummer and Bankleitzahl (and, from that, you can concatenate the IBAN).

> Same here. John gave you a card? Cool, maybe it can have a QR code you can scan. Or do you enjoy reading and typing long URLs and having to double check them?

I visit wikipedia by typing https://en.wikipedia.org/wiki/<topic>.

If a URL is designed well (HN’s aren’t), this is very easy. Wiktionary and Wikipedia do it well, reddit’s is also okay, e.g. https://redd.it/7wwtqy – most sites, in fact, work nicely like this.

> Cool, maybe it can have a QR code you can scan.

Most don’t.

Maybe you remember the time, just a few years ago, when everyone knew their phone number and email, and their friends’, by heart? Why force people to change that? Relying on autocomplete and autofill for everything is horrible, and creates massive network lock-in.
I have not seen dynamic user name lookups work well in practice though, where the system has made it convenient enough to actually be used consistently. A different approach might be to leave the name as is for past conversations but use the new name for new interactions (and some way of showing the past name, xxx (formerly yyy) for new posts and xxx (now known as yyy) for past posts) - as is quite common that people manually do in the real world (and on facebook). Not perfect and quickly gets complicated.

I'd argue that a username does not have the same function as a name. My name is not an identifier and most have not chosen their name - which is also why (I believe) the first name change is free of charge where I live. In most cases you can also create a different account. Depending on the type of service this might not be desirable but in others it is exactly what you would want.
The mess you describe is only a problem if the products you produce suffer; chroots, virtualenvs and Snaps are a nice way to handle the resulting problem.

What's ironic about your statement is that there are many in the US that clamor for "free" university education for "everyone" -- citing how it's done in Europe. However, like everything, there are tradeoffs and unintended consequences that go beyond the simplistic thoughts of the politically and economically naïve. The University of California system, in my amateur opinion is extremely good. In fact, the state university systems in most US states are all of pretty good quality. I spent a bit of time living near the University of Avignon (France) and, compared to a typical American community college, I was very suprised at how deficient the French university was. In France, university is "free" but as you said, you get what you pay for. Of course, there are exceptional European universities and there are terrible American universities, but overall, American university systems seem to be much better than the equivalent in "free" university countries.
