A couple of questions and I'll buy it.

1) Does it feature 2-way sync? ie changes on playlist/data/playcounts on mobile will also change on the desktop.

2) On mobile, when browsing inside a single artist, do you have the option to see all songs by a particular artist? Apple stock Music only allows by Artist then single Album and I hate it.

I get what you and dang are saying, but I'm not so sure it's that simple. If I follow this idea to its logical conclusion, I'm left with simply nihilism. You can use this same reasoning about anything. Why go out and march or protest or do anything for ____ (insert any cause here)? Any single action you do is unlikely to solve a big problem. But everyone can't just give up on everything and go for a walk when things seem hopeless or unlikely to change.

Social pressure is an important phenomenon and public opinion can really end up changing a lot over time, and I'm not so sure it's useless to add numbers to your side of an issue and contribute to a sense of societal consensus. It seems very difficult to pick out exactly what kinds of actions move societal opinion over time. E.g. what were the singular actions between the years 2000 and 2015 that were able to shift opinions on gay marriage so dramatically and make it so widely accepted now in America? If everyone that was fighting for this cause over that time had assumed it was hopeless and just given up and gone for a walk instead, it's possible this shift would not have happened.
Hertz got out of bankruptcy because they have a (somewhat) profitable business model and a lot of assets they sold off.

I don't think that applies here - at least not without massive growth that seems outside the realm of possibility.
It's worse than that: in terms of preventing infection, vaccine effectiveness drops to 16% after about 6 months [1] (see the graph on the final page).

Severe disease infection seems to last longer, but a natural hypothesis from this data is that it would fall off as well, just delayed by some unknown amount of time. Unfortunately, we probably won't find that out in any transparent way, since Israel's ministry of health [conspicuously] just announced that they'll no longer be including the relevant information in their daily data releases [2].

> The only real safeguard is layer upon layer of checks

But this is one such check. As I remember it it was at work in the fall of the Soviet Union, and it was worked around at Tiananmen Square (where they brought in troops from the country, not trusting the ones on site to be brutal enough).
Same here. Houses of cards can stay up as long as there are enough people who believe that it's not a house of cards.

State governments have to turn over all of the DL/ID data to the feds these days under the new backdoor federal ID law ("Real ID").
And again, people see arguments like this attempting to liken Tesla to a clearly fraudulent scam (the truck didn't even go!), and is it any wonder they threw up their hands and figured NKLA was a good bet?

Look, nitpick about FSD if you like (I bought it, FWIW -- 100% happy customer). But don't claim it's the same as faking a motor in a truck that didn't have one.
> just isn't worth the effort for the average ownership span.

There's no rule that says you need to hold stocks for the same average period that the rest of the market does. Analyzing securities and purchasing those that are undervalued is still an extremely profitable activity at many hedge funds and prop trading desks. The fact that the average investor is more FOMO-driven these days only makes sound analysis more valuable, just like playing poker with a drunk newbie will have higher variability but better expected value.

Every stock seems to have a little bit of this factor.
Favorite quote:

Yea I remember when it went down, being a lifelong user of VLC I was pretty active there. It seemed obvious to me it was a joke, but so many were sure it was not.

Happened here the other day in a Perl thread. Someone made a pretty funny (to me) joke. Having used Perl too much I appreciated the joke but some read it differently.

Like the tabs v spaces, Vim or Emacs, to me it seems funny and nothing to get riled over but some just become so invested in taking offense/personal.

they used to have you read wiki articles like, 6 years ago? I feel that over the years, Duolingo started focusing way more on the game aspect than learning.

The spaced repetition is also mostly gone, only somewhat available on desktop.
Nothing is ever "free". We know from GMO foods that making bigger versions comes with a tradeoff of worse nutritional content. This will be similar.
Awesome! Does it use wasm-simd? If it does do you know how much impact it has on the performance?
I know quite a few people who stopped regularly showering with soap and shampoo. They do it just on occasion and otherwise just use water. I can assure you that they do not smell bad. Consider doing so myself, and have heard it is better for skin and hair too. But I didn't look up any solid material on whether this is more healthy (a search will probably lead to a lot promoted science that urge me to use skin products).
For some reason I always read all stories about Clubhouse, and it seems like it gets written about quite a bit. I've never once thought "this is something I want to try" but I love reading about it. Feels like one of those things that has been so perfectly hyped and promoted by the right people, but when it comes down to it, there's not much there. If nothing else the marketing team sure got everything right.

It kind of looks like Quibi to me, it's obvious that it's not going to be a big hit or maybe even be around in a year. (It was also obvious to me that Snapchat was going to fail, so what do I know?)
Do you actually play it? I'm a bit the same about reading about it, yet I have never once played it for myself!

I was going to post the same thing about Star Control 2. I found a video to highlight it. https://youtu.be/nj8j7IGQP6E?t=188

It needs to be emphasized that the game had hours of music. Every different race encountered, every mode of travel and even different planet types had different music. All through a PC Speaker and would run on a 286. The game was a technical marvel for the time.
Are clubhouse conversations recorded?
I bought a house with a sunken living and wanted to raise the floor. We used blocks of this stuff to fill up the sunken living room, so we only had to use 6" of concrete on top. I was surprised when I found out, but my builder says it is common.

I don't know if I would use this stuff outdoors, though. We had a bean bag chair full of polystyrene balls leak outside, and I was finding the stuff in my yard for years.

I got a lot of enjoyment from it, but was during winter, under lockdown, with opportunities for real-world socializing greatly curtailed.

At it's best it's like walking down the hallway of a grand university, able to drop in and out of any of the lectures and seminars in progress, not disturbing anyone but able to contribute if you want.

Lately the reality is more like walking down the main thoroughfare of a low-end shopping mall, flanked by somewhat tacky shops you have no interest in entering. Like you want to find a specialist book store, but everywhere's just selling e-cigs and phone accessories. I haven't really signed in for months.
There are places to ask the question "I think I need X. Is there a better solution?"

But the answer to the question "How to do X?" really shouldn't include more than a passing reference to "Here's how to do Y." If X is impossible, then that is of course the answer.

And as others have indicated, the most frustrating scenario that happens over and over is that once the "How to do X" question is asked, you can never get an answer to that question if the original poster relents and agrees that what they really need is an answer to "how to do Y?".
One tool that I don't think gets enough love is the "git-fixup" add-on. It looks at your commit log and recommends relevant commits to fix-up based on your staged files.

If you are using fixup commits in your PR review process it's essential.
It's significantly different in degree, but not in kind.

Posts may be one-dimensional, or strive to find common ground. Failing the latter makes them more irrelevant.

This, in the context of having a moderation system to filter contents in the first place.
There's a further complication; in most countries hospitals are required to treat (emergency) patients. This directly puts medical workers in conflict with people who ignore their advice and then require an ICU bed. There is no autonomy for hospital workers; they must quit the field or take the additional risk. This isn't a sustainable situation nationally because the government is not likely to either force them to work or rescind the laws requiring all hospitals to treat all emergency cases. Arguably something else in the rights tradeoff should give way before the medical system is dismantled from the inside or mandatory emergency care is abandoned.
"German police have been accused of using Stasi methods"

I'm sure the Stasi also used fingerprints, yet no-one is asking German police to give those up. Perhaps the goals, rather than methods, are what should be under greater scrutiny - going after dissidents is not a thing of the past, they're just not called such:

Germany’s existing Network Enforcement Act (aka the NetzDG law) came into force in the country in 2017, putting an obligation on social network platforms to remote hate speech within set deadlines as tight as 24 hours for easy cases — with fines of up to €50M should they fail to comply. - https://techcrunch.com/2020/06/19/germany-tightens-online-ha...

Kids fight with each other because they need attention. The best way, but this is hard, is to give them undivided attention for as long as they want it.

Oh man, I'm sure only people who've actually played the games back then can relate, but I got literal goosebumps upon hearing that music when I played that video. I think the fact that it's played from a PC speaker added that much more level of nostalgia.

Wow, this is a very real problem and I'm glad to see it addressed.

Every Friday my Abuela calls a stranger for manicure/pedicure they've known for years that she heard about from another friend, from another friend... Word of mouth, like most things in LatAm. They're not certified or anything, but they do a decent job.

I've always wondered about their background because they seem to hang out for too long at the house, and it sketches me out.

On my end, finding a good barber shop or beauty salon for my hair has always been a huge pain. The quality of cuts is extremely variable and online reviews are scarce, aside from maybe Facebook. There's no scarcity for cheap $10 cuts but the variability is incredible in quality. Some dude at the $10 barber shop could be a fantastic, trained stylist. But then next time you come in some other asshat ruins your hair.

Aka it's a bit of a crapshoot but it's all you know and what's accessible. I'm a broke college student and can't afford much more than that.

You're damn right that the beauty industry in LatAm is a bit of a wild west. I have a quick question: what are costs for customers like?
> My mask protects you, your mask protects me". There is no physics behind this, masks aren't one way barriers, were never studied or sold as such, nor are they capable of stopping the sort of explosive air pressure caused by a cough.

The proposed mechanism is that during exhalation (or more importantly speaking and coughing) there are relatively large droplets of saliva/mucus containing viral particles, and these droplets can be catched by masks (they are big and move more balistically, so masks need not be airtight).

But once these droplets are in air, they dry to (much smaller) aerosol that cannot be catched by masks, you would need properly fitted FFP2/3 respirator.
Gimme gimme gimme is the output. IMO the joke making it obviously different is better than the joke making it subtly different. Imagine how annoying it would be if it only had a 1 in 100 chance to happen, for instance.

For me Duolingo is woefully ineffective. A far better method is Pimsleur plus Anki. Ankify the Pimsleur audio, make your own Anki cards with most of your vocabulary in cloze phrases. Ankify the audio on as many of those cloze phrases as you can using native speakers. Work at it daily. Use a textbook to learn the grammar. This is a system that works. It’s the fastest way I know of to begin understanding languages intuitively. No need for mental translation. No difference in how your mind responds to “What do you want to eat?” and “你要吃什么?”

Of course, Duolingo’s valuation isn’t connected to success in learning language. It’s connected to success in convincing people that they can and should learn a language.

Estonian ID-cards contain 2 key pairs: authentication and signature. Certificates’ DN contain both: owner’s full name and Personal Code. Personal Code contains your sex and birth date. Also, there’s data file on chip containing all textual data seen on the card, no image. So it’s easy to use ID-card in both, physical stores (reads data file for Personal Code) and e-shops (reads certificate after auth). This document image service was just a convenience service to download your document image. Problem causing the issue was that auth certificate path was not verified during authentication, so you could impersonate by generating fake auth certificates.
What's interesting is that the patients often have absolutely no cognitive impairments & are regularly seen by their doctors.

Incredible piece of work, and an inspirational process. Your book helped me write my own language compiler. I love the way you explain the pratt parsing technique and also the way the lexer and parser work together so you don't have to read the whole file at once, and how advance(), consume() and expect() functions work. It all just works together beautifully
With calibers there is a difference between american .22 and european .22. As I understand it, the american measurement is slightly larger as it includes a bit of the rifling groves whereas the European standard was only the bullet width. So the same bullet measures slightly larger on the american scale. Or I might have that backwards, one of the two is different.

> Nikola was building barely functional prototypes of their trucks years before Tesla was building barely functional Semi truck prototypes, for the record.

If by "barely functional" you mean a metal skeleton on wheels that rolled down hills, then yes.

I'm not a shill for Tesla as they definitely have made very questionable claims in the past, but to claim that Nikola's semi is in any way similar to Tesla is a bit of a stretch.

And the time of plenty is primarily driven by monetary policy, is it not?
Google uses a monolithic source code repository, so all of the source code is presumably still present within that repository. However, there is probably nothing that they can feasibly sell, as that source code is dependent on other parts of the Google infrastructure that are all part of that repository. It would probably be just as much work to extricate it from all of those entanglements as it would be to rewrite the product from scratch. Indeed, you could just go get an open–source product like NewsBlur for free and use that instead.

I remember reading Graham for a finance class in the mid-2000s, and even then it was several decades old.

It's a relevant read if you work in securities analysis. If you're an investor however, the takeaways of the book are more philosophical than actionable. Too much has changed in the market since Graham's time.
