> A complex disease cannot be solved through a simple magic-bullet cure or vaccine. This especially true when the infectious agent is an airborne virus with not only one, but many animal reservoirs, being a known zoonosis that can be found in numerous species around human habitats. As a result, claims for its eradication are naïve. In fact, some scientists are suggesting that ‘full’ herd immunity to end this pandemic is probably impossible because of new variants arising, doubts over whether the vaccines can prevent transmission, signs of waning immunity, and inequities in the global distribution of vaccines.

I was quite disappointed that Car2Go didn't work out - it was a car rental service similar to e-scooters, park anywhere, pay by the minute. They used Smart cars, which were fine (they were owned by Daimler), but it would have been a great system even with cheaper cars and disallowing highway use.

Seeing cars like this makes me wish someone would try it again but with a different fleet.

By what metric? Despite having a vaccine now, the US is currently averaging ~150k new cases per day, as opposed to ~45k when that tweet was posted.
Anecdata for anecdata, I've never seen 90% of big cars on the roads around ever regularly carry more than one passenger at a time to/from a desk job (or a meal commute) that doesn't need any large hauling ever.

"Big=safe" may not be smart reason to get a big car, but it's absolutely a common ("popular") one in the US today. Just looking at how cars are advertised, there's basically two main marketing pushes "just look how safe it keeps your family" and "just look at the hobbies it could let you do that you probably won't actually do but think you will", and yes that second one is a pretty equally common reason people buy them, but both messages get about equal air time in the US and seem common in reasons people buy them.

I realize I'm very dismissive of people buying them for "hobbies/interests", but over-buying capacity based on "perceived need that doesn't actually exist" is a trap that also makes the roads less safe and should be regulated.

This isn't really a sight-seeing thing, but grab a cheese steak! Pat's/Gino's are the famous spots where everyone takes photos, but IMO they're mostly tourist traps at this point. Worst cheese steaks I've had within 100 miles of Philly. Jim's is a good spot, plus it's on South Street which is a good area to walk around in.

The South Street area is also home to a bunch of mozaic murals by Isaiah Zagar, which are definitely worth checking out. There are official tours, but you can also just check out the neighborhood map here and explore some of them on your own: https://www.phillymagicgardens.org/about-us/mosaic-mural-map...

If you like walks, check out the Schuylkill River Trail - it got caught up in the recent flooding so I'm not sure what kind of shape it's in right now, but I assume it'll get cleaned up pretty quick if it hasn't been already. The view of 30th Street Station and a nearby USPS building is pretty cool at night. I've heard it can get a little sketchy if you're down on the trail at night, but as a 6ft tall white guy I never ran into any issues on the route walked home from work for ~8 months. Your mileage may vary, but the worst thing I ever encountered was kids my age smoking weed down by the river.
It is higher-level than actix, though it's still surprising to see it as low as it is. I'm curious what the story is there too. It is significantly higher than Express and Flask, though it's lower than raw NodeJS and PHP.

I guess maybe these benchmarks only test the overhead of the framework itself, and ignore the benefits of having your business logic and middleware written in a faster language? The tests for node and PHP would pretty much only be running battle-tested native code if that's what's going on
Hardly "just a couple of notches above the bottom of the market". They tend to be rather new, high mileage for their age but not high mileage in the grand scheme of things, and maintained by professionals. They're just a couple of notches below brand new.
Although the article mentions "polarization", when I look at the intensity distribution graph, is that not more an example of "pyramidal" - ie with a substantial amount of work between easy and hardest (VO2) intensities (see the bars for aerobic, tempo, threshold), rather than just being divvied up between Easy/VO2 with no-mans land in the middle.

> I find it fascinating that companies still do not mention the Gflops/watt/$ for their products?

GPUs win in TFlops (like 20 or 40 TFlops these days), and TFlops/watt (A modest 20 TFlop GPU these days would be under 400W).

GPUs also have 1TBps memory bandwidth thanks to HBM2 (on the high end), or at least 500GBps (thanks to GDDR6 on the low end).

Any serious compute problem with "obvious" parallelism will run on a GPU these days. CPUs are for sequential problems... (and running many sequential problems in parallel: which GPUs are kinda bad at actually. No GPU would ever be able to serve web-pages like a CPU: branch divergence is just too high)
The pollution from mobile phones is actually not even worth thinking about.

Meanwhile the media is full of anecdotes about kids dying and people saying “I regret not taking covid seriously” and stuff like that. Then you have that Dr. Ding guy on Twitter spreading fear and panic. Is that not dangerous misinformation?
Yeah, many more metrics to look at as well. Like lactate threshold (often measured relative to pace in running, or wattage in cycling (FTP)). And while they correlate, even they cannot even predict performance.

For instance I measured my ftp, did a training plan and measured again. No change, but still got better results on my rides. Real world cycling is "punchy" with accelerations and hills etc. So my steady state performance hadn't increased, but my ability to endure going over lactate threshold and come back had.

And also the other way. When my friend started cycling, he was already an insane runner with good vo2max (70+). But his ftp on cycling was comparably low, since his muscles couldn't handle that lactate build up from this unknown moving pattern. Of course he quickly improved, but it's another point showing that vo2max doesn't necessarily translate to performance in an event. (One could argue him redoing the vo2max test on a bike would have yielded a different score, though)
I'm also not sure where you get that idea, it's clear when purchasing that Autopilot is a fancy cruise control to assist drivers and that full attention is required at all times.

Inconveniences aside the economy seems to be doing rather well despite 4.5 million people dying over the course of 18 months due to a new disease.

I do think it has exaggerated some long-time inequities and we have an opportunity to make improvements (for example, look at who's net worth increased the most during the pandemic, and by how much).

Early China low-cost EV's were simple brushed DC motors. In today's world, brush less ought to be cheaper and better. All the fancy features like traction control, regen, burst acceleration, etc become entirely software features, so cost nothing if enough units are sold.
Convey Digest Prize Fund
I think an app store would be a great location to not have optional payments for open source software if developers do not want it. Users can choose to go get and compile the source, download a third-party binary and keep it updated themselves, or pay for it and know it's directly from the authors and automatically updated and getting a path to support and the interested customers know the only people submitting reviews are people who paid for it and not drive by opinionated users like is common in open source software.

If I'm not mistaken, Switzerland the wealth tax hits everyone as well. The starting is something like 200K CHF. That said, the actual percentage is very low, like 0.2%. Having read a few bits of the Swiss tax code, I'd actually prefer to have this wealth tax like that over a cap-gains tax, since it would overall be a lower percentage of my capital asset appreciation than a CGT.

> What's on offer is a significant (order of magnitude) reduction in the number of violent gun deaths.

I think I wasn't totally clear about the point I was trying to make.

Very very very few politicians in the US (I can't name a prominent one but I'm hedging) are for any sort of firearm prohibition that would put us in line with any of the nations we are often compared with. So, given that, the restrictions being proposed will not and should not be expected to bring us in line with those nations. Therefore, the question I'm asking is, given the proposed restrictions, what benefits should we expect.

The point I wanted to make was that the answer to that question, "what benefits should we expect?", is basically none from the current viable proposals and that's why, while I am for more gun control, I am against most existing and proposed gun control measures as I feel they are either completely ineffective or overly burdensome for their effectiveness.

I find the oft-said quote of "If we can save even one life..." type of argument a massive red flag.

If you turn 360 degrees, you end up facing the same direction you were in before the turn. A U-turn is a 180, not a 360. That is why in great grandparent, "did a complete 360," does not mean what the writer thinks it means.
Many lifted pickups already violate regulations in most places, they're just not enforced.
No it's not a direct measurement of endurance capacity. It is, as the units imply, a measurement of your maximum rate of oxygen metabolism over a very short period, as normalized by body mass.

There is some correlation with endurance capacity. But that relationship gets progressively weaker as you go out to longer efforts.

One thing I don't like the recommendation system is that it offers videos I already watched and even bookmarked. It also offered videos from people I subscribed but this is OK-ish because some accounts have hundreds or even thousands of videos.

Basically, all recommendation system are based on one hypothesis: I know more about your preference than yourself. I can't say I agree with it.
Ask HN: Need for visual representation of Python graph code for easier debugging
I have been doing interview prep. Was finding debugging graph based questions more difficult than usual questions.
So I wrote a small piece of code (right now valid only for some cases) which helps visualize your graph algorithm in jupyter notebooks. For example you could write a code like this. [Generator is the class I have written]

def dfs(root):
global g
g.take_snapshot(locals())
if root.left:
dfs(root.left)
if root.right:
dfs(root.right)

g=Generator()
g.register(root_node_var=None,pointer_var="root",root_node=root)
dfs(root)
g.render_bt_graph()

Would something like this be useful for interview prep?
Engineer-types certainly do try to loophole their way around the law in a way that's not how the law actually works, but this article is not really engaging in that I don't think (for one, it calls out the practice).

Cablevision is absolutely by its terms hugely reliant on the nitty-gritty technical details of how the DVR service there worked. The court had to kind of wind itself up in knots to work around the existing MAI v. Peak precedent (copies to RAM are actionable infringing copies) and the fact that the service existed just to make these copies, so it gets very in the weeds on how things are stored and the amount of time things are in buffers and so on.

Ultimately, it's probably true the most important thing was that Cablevision were an established player in an existing, uncontroversial market and they were making an iteration on the already allowed and understood "time-shifting" recording systems. But other players in the market shouldn't really be faulted for taking the court at its word that the details actually mattered. Sometimes they really do!

MAI v. Peak, mentioned in the article and above in my comment is a great example of that: the 9th Circuit holds that a computer copying the OS into RAM is a "copy" for the Copyright Act, thanks to the statutory definition of a work being "fixed." Result: a repair technician violates copyright by turning on the computer because he doesn't have a license. This is kind of the polar opposite type of decision to, say, Aereo's case: it's actually quite disruptive but hinges more on the literal definitions in the law and things like the computer not being on already, thus requiring the "copy" to be made. Congress actually changed the Copyright Act to counter this decision but in an extremely specific way, so the general "stuff in RAM is fixed and therefore a copy" principle remains and comes up often.

Aereo lost because they would upset the applecart of retransmission fees, Locast similarly though for nominally quite different reasons. It can be quite difficult to tell in advance if you're going to get a "letter of the law" decision from the courts or something more results-oriented, even from the same court.

An often-unappreciated wrinkle is the more or less total dysfunction of Congress leading to court decisions taking on ever more importance. The courts themselves aren't blind to this, leading probably to more results-oriented decisionmaking than there might be otherwise.
Agreed. Over the past decade I've commuted by some combination of all of LA's train lines, and the orange line, too.

Red and purple and the best. Although purple's lack of distance degrades the value. Green, yellow, and expo are decent, but Yellow running at-grade degrades the utility somewhat, as for the expo line, as you said. The Green line didn't freaking connect to LAX, completely negating it's potential utility.

Blue line and orange line are by far the worst, being entirely at street level and interrupted constantly with cross traffic.

Honestly, what really needs to happen is: 1) Purple line completes intended extension. 2) Submerge the blue line and install new station for connection w/ green. 3) The orange line needs to be submerged and absorbed by the red 4) New rail line from the I-5 that follows the 405 S. It would connect with the expo, LAX/green lines, and terminate with the blue line in LB. The red line would connect/intersect with it slightly north of the 101.

Already, those are pipe-dreams due to... well, everything about building public infrastructure. But LA does have the bones for some decent public transit, even if they'll never really invest in it.

I keep hearing that car rentals are expensive and terrible, but it's not at all matched my experience. I just rented a car for last weekend 9/10 - 9/12, and it cost me 95 dollars including taxes and fees for the whole weekend.

> Jam 80 Cores, 768GB of RAM into E-ATX Case with This Tiny Board

The headline sounds like a brag, but isn't exactly impressive.

There have been multiple EATX Dual EPYC motherboards on sale for some time now. The limited board area means only one DIMM per channel, but with eight channels and 128GB DIMMs that still means you could have 128 cores and 2TB of RAM in a single EATX system with "ordinary" AMD hardware.
This will have to be settled in court eventually (I'm guessing very soon, looking at all these videos). It's very unlikely that car manufacturers will be able to avoid all responsibility just because of fine print in the terms of service.

Nobody in the USA will buy it. Anyone who claims they will, and doesn't own a Mitsubishi Mirage or first-gen Nissan Versa is lying. These cars stayed under $10k new for a while, and yet never really sold well in the USA. It was even possible to get a Ford Fiesta for <$10k new after discounts up until they stopped selling them in the USA. They seriously sat on lots for 2-3 years before being auctioned off (and probably sold at used car dealerships for more than they sold for new).

Americans don't buy cheap new cars, and it's not because they don't exist. Manufactures would love to get Americans buying cheap new cars, but Americans stubbornly refuse to. They claim to want cheap new cars, but they take one look at an actually cheap car and decide that a 10 year old <nice car> is a better buy.
