zzleeper··on Pfizer 91% effective in updated data, protective against South African variant
I have two friends who got covid twice. One had it first in July and then in January. Second one was brutal, maybe b/c it was likely the Brazilian strand, or maybe because the second time your lungs are still recovering. Who knows.

But I would advise you to take it.

zzleeper··on Julia 1.6 Highlights
That was also a huge problem for me. I sometimes open Stata/R/Python/Excel, run a few snippets, and I'm done.

All four take seconds to start (or even less), and Julia felt like a huge step back in productivity.

If it's really fixed, might be good trying again.

zzleeper··on Germany pauses AstraZeneca vaccinations as a 'precaution'
53% is nothing. Peru peaked at 260% excess mortality in February (2nd wave) and 230% in July (1st wave). My Facebook was (and is) a depressive mess of sad announcements.

Source: https://opencovid-peru.com/reportes/sinadef/ (1100 deaths per day, compared to 300 average for 2019)

zzleeper··on Germany pauses AstraZeneca vaccinations as a 'precaution'
I was well aware even by March that masks were the way to go. It was a simple lie, by e.g. the Surgeon General, in order to try to save masks (while they didn't even start ramping production of them!)

But of course if a government official lies to you about your own health risks then that has very high costs, much higher than whatever masks were saved. They could have just said "masks are useful, but you need to be trained to use them correctly, they are difficult to manipulate, etc. and they are very scarce so sadly let's stay home and let doctors and nurses use them".

I might sound as if I'm upset at that, because I REALLY am. I hate when governments lie, even if they are "white lies", and I hate when they treat their constituents as kids.

zzleeper··on My bank sent me 64 copies of the same debit card
Most apps require constant updates or they stop working.

I had set up my iphone to only update on wifi, and was travelling for a month or so only using mobile network.

When I tried to get an uber, I realized the app didn't work correctly (the driver appeared to be in the middle of the ocean). Same for other apps.

Games and apps that don't use heavy server code work fine, but google maps, uber, whatsapp, facebook, and some of the KEY things will break eventually if you never update them.

zzleeper··on New algorithm breaks speed limit for solving linear equations
Does anyone know how big are the constant terms here?

A few years ago I studied and partly implemented an earlier (related?) work by Peng (on graph laplacians and SDD systems: https://epubs.siam.org/doi/abs/10.1137/110845914 ) and the big-O improvements did not seem to compensate for the larger constant.

zzleeper··on Are You Trading or Gambling?
Argentina is not small. It's the second largest country (in pop and area?) after Brazil
zzleeper··on “WSB veterans know that they're making a suicide charge for the memes”
Are you two sure WSB hasn't reached an eternal September event? I find that with 8MM subs, the signal-to-noise ratio will likely remain just too high.

I've been looking for alternative subs, but besides e.g. theta gang I haven't really found anything useful

zzleeper··on GameStop staff, paid $11 an hour, find day traders tone-deaf
How exactly did GameStop got a bailout? They did not issue additional shares, so didn't really got anything from this besides maybe some publicity
zzleeper··on Plotnine: Grammar of Graphics for Python (2019)
A lot of people swear by ggplot and other grammar of graphics tools, so I have an open question. Let's take an example from the page:

  ggplot(data=mpg) +\
  geom_point(mapping=aes(x="displ", y="hwy", alpha="manufacturer"))
How much easier is that from

  g = ggplot(data=mpg)
  g.geom_point(mapping=aes(x="displ", y="hwy", alpha="manufacturer"))
Or, for instance:

  ggplot(mpg, aes("displ", "hwy")) +\
  geom_point(aes(color="class")) +\
  geom_smooth(se=False) +\
  labs(title="Fuel efficiency generally decreases with engine size")
VS:

  g = ggplot(mpg, aes("displ", "hwy"))
  g.geom_point(aes(color="class"))
  g.geom_smooth(se=False)
  g.title = "Fuel efficiency generally decreases with engine size"

What am I missing?
zzleeper··on Robinhood is said to draw on bank credit lines amid tumult
The volatility of the Gamestop is just insane. People think it's because of the short squeeze, but it's not just that but the fact that the stock goes from $100 to $400 to $200 within the hour, and then as OP mentioned you end up with a lot of your liquidity stuck in Gamestop until the contracts settle.

unfair election? what exactly do you mean?
zzleeper··on SARS-CoV-2 501Y.V2 escapes neutralization by South African COVID-19 donor plasma
Worth noting that peer review is also a bit (or a lot slow) and not perfect, and that all peer-reviewed studies have in the past been not peer reviewed.
zzleeper··on Anthony Levandowski Pardoned
I am op (asked the question) and even though I don't agree with throwaway, I appreciate him having the time to respond (so I upvoted.earlier to try to offset the downvotes).

Im also downvoted btw, so this goes both ways.

zzleeper··on Anthony Levandowski Pardoned
I wonder how all the Trump supporters on HNs (maybe 30% or so of commenters, no idea about lurkers) are reacting to this.

Levadowski pardon, the spy, the swamp, etc.

zzleeper··on How Silicon Valley destroyed Parler
I used to be a fan of Greenwald, but after seeing his failure to condemn the Rs (and Russia), got very disillusioned.

Also, he is propagating lies:

zzleeper··on Two Worlds: So Much Prosperity, So Much Skepticism
Same here. Feels like the forest fire stories. Every time the msrket throws a tantrum, central banks print money, and everyone is kept happy (for now).

Oh, the wonders of what you can do in low inflation environments, at least for a few decades

zzleeper··on The Progressive Purge Begins: Tech’s stampede will lead to more populist anger
I'm just surprised at how close the US came to stop being a democracy. A bit more planning about what to do when they breach the capitol, a few more Qanon captains across the river at Ft Myer, or a few 100ks more Trump supporters here and there in the polls, and things would look very different now.

And of course, this is just the beginning. Right-wing extremists now this; the sooner we realize that we are against an enemy that wants to overthrow democracy, the sooner we put a better fight against it.

zzleeper··on The Progressive Purge Begins: Tech’s stampede will lead to more populist anger
I find it very interesting how extremists now attempt to appear as moderate. For instance, take the submitter of the story:

Says it's not worth it to fix global warming: https://news.ycombinator.com/item?id=25358094

Says the rich should be able to get the vaccines before others by paying to skip the line: https://news.ycombinator.com/item?id=25472334

Says the rise in people identifying as transgender is due to "peer pressure": https://news.ycombinator.com/item?id=25348701

And that's just over the last few weeks or so.

Of course, no comment at al condemning the attack on the capitol, but when the attackers and their supporters face backslash, suddenly they scream murder.

zzleeper··on The Progressive Purge Begins: Tech’s stampede will lead to more populist anger
I started reading it circa 2008, created my account in 2009.

In a way, HN is still a reflection of society, although more civil due to pg (then) or dang (now) moderation, plus the fact that a lot of users knew each other back then.

Nowadays, I'm constantly amazed at how the right is able to turn ANYTHING into someone else's fault. The right divides the country ("let's own the libtards", "the election is a sham", etc) but no, it was the left! The right does a coup, but no, it is the left that cannot let bygones be bygones.

Do they think we are dumb? are they dumb? what is going on?? Black is white is black, war is peace, etc. etc. and no one even blinks at this.

zzleeper··on The Progressive Purge Begins: Tech’s stampede will lead to more populist anger
WSJ ceased to be a serious newspaper when Murdoch bought it. But of course, almost half of the country voted for 2020 Trump, so almost half of HN probably likes him even today. So you will see this and more like this being upvoted.
zzleeper··on Facebook Indefinitely Suspends Trump
A lot of people over here are very pro-trump, and just use this as a way to defend him.

It's the same reason why anything non-tech gets flagged nowadays until dang removes protects the threads: they don't want to see news attacking their "Dear Leader", so they flag it as non-relevant. If it was a story about a democrat doing something wrong, I'm pretty sure they won't get flagged as quickly.

Dang: would be REALLY interesting to compare who is flagging with their comments in these and other threads.

zzleeper··on Ask HN: Who is hiring? (January 2021)
Hi John,

Nothing to do with the two positions, but have you ever considered a markdown editor? My pipeline is markdown -> pandoc+filters -> latex, so nowadays I only use Overleaf when the papers (or the coauthors) really demands it.

zzleeper··on Is unprofessional my personale website?
Get some pointers from a friend who is a native speaker. I still do this today even though I'm (IMO) well versed in the language.

For instance:

welcome on -> welcome to

web-side -> webside? (unsure)

working as front-end -> working as a front-end

i want u -> unsure what that means

besides that, any specific front-end js platforms? (maybe put angular before jquery in your cv?)

on mobile, the about me page has the linkedin/github icons on top of the "contacts" page. lastly: besides those minor things, your website is PRETTY COOL

zzleeper··on Adobe Lightroom v6 is Falling Apart
Any suggestions for an Acrobat alternative that can do simple things such as rotate a PDF or extract a page from it?

I use SumatraPDF as my daily PDF reader but still have to resort to Acrobat for those things. And the latest update (that requires creating an online account!) finally did it for me, I'm sick of Acrobat.

zzleeper··on Why is the Google Cloud UI so slow?
Turbotax created the problem they are solving. Filing taxes in other countries is much less stressful and a lot simpler.

zzleeper··on Moderna Covid vaccine candidate almost 95% effective, trials show
Thats why you have a lot of people in the trial, and why its a double blind
zzleeper··on RCEP, the world’s biggest trade agreement
Exactly. If they don't sign, they get left out. And then what? wait until the US somehow decides to join and only then join?
