> I think you're now making a new claim that there's some continuum of customer service responsibility versus profitability. I don't think that was the original claim, and that's not what I'm claiming.

> "No company should be let off the hook for having awful customer service" does not preclude judging one of the most profitable companies in the world more harshly for having awful customer service.

What you're describing in that second pulled quote is a continuum of customer service responsibility versus profitability. According to you, the more profitable company has a greater responsibility than the less profitable company does.
I had one of those for the first time last night (new Macbook Air) on 10.15.4. Shame that you’re seeing it in 10.15.5 too…
I don't know whether there's a large correlation, but I believe it would mostly be in the severity of outcomes. Depression isn't "because life is hard", but life being hard makes dealing with depression harder than life being easy.

I know people who are very wealthy who struggle with depression, I know people who are very wealthy who don't even really understand the term because they've never experienced anything remotely close. And I know both types who are not wealthy at all. From my personal experience, money doesn't matter in that regard. But it's definitely better to struggle with depression without the added stress of keeping up with the bills, and when you've gotten through it, you're having a good life if you've been rich before, and you're going to have to pick up the pieces and try to glue them back together if you haven't.
> It's unfortunate that a lot of programming courses add it in as a "here's a five-minute intro to git" sort of thing. As you have experienced, that really doesn't work.

That is indeed true. Only memorizing the git commands can get you going, but is often not enough. Eventually you'll mess something up and end up throwing more commands at it until you either fix it or give up and reclone the repo.

There are likely other sources available, but what helped me get a good understanding of how git works was Paolo Perotta's "How git works" Pluralsight course.

I wonder what the "investors" mailing list is about.
Sketching Out a Muon Collider
I feel like this is too deep into the conspiracy domain. There are so many videos and moderators, that, of course, there's assholes in there. But the chance that this one specific video ends up on the task queue of the fraudulent moderator just seems too low to be a feasible strategy.
Very. My MBPs are normally plugged in and the battery is almost always degraded by the end of year 1. I’m looking forward to this update just for the battery protection.

(And I know I should try to keep my MBP unplugged as much as I can, but it’s normally docked.)
Maybe this link will work: https://www.supermemo.com/en/archives1990-2015/articles/20ru...

If we go with the example you mentioned as a card:
“You’re at a conference and you start talking to someone about [The Great Depression.] What are some key points to remember?”
there are a few issues

tl;dr by being complex but still a single card SRS isn’t actually going to strengthen the memory very well and you’ll be stuck with short intervals on a card that will take at least 10 seconds each rep. It will still work but it’ll take up much more time than it should. (The link explains it much better)

But it’s not a bad idea. If you answer the card and write out an answer, memorizing pieces of that answer in accordance with minimum information principle will leave better memory effect. While you might have 20 subcards, over time these will get much more accurate intervals from being atomic and actually take less times in rep than your massed question.
Targeted lockdown was a good idea in the context (not that much different clusters).

Sweden was since the beginning at the place where France will be next week, but Sweden did not have the Mulhouse cluster that crippled multiple hospitals in eastern France.

Many thanks to Switzerland and Germany for helping us saving a dozen patients by the way.
Examples help quite a bit. Tell a story, a gamma ray causes a mutation in the very room you are in and causes a common virus to be virulent and deadly. It takes 2 days to make you sick enough to spread and is virulent enough for each person to spread it to 8 people on average.

So 8^11 is about the people on the planet, so in 11*2 days everyone on the planet will have it. Sure one a noticeable fraction of the planet have it, the rate of spread will slow, that's called heard immunity.

Then maybe discuss how with such quick growth that some countries drop the ball. What looks like a over reaction while it's happening looked like a under reaction in hind sight. Mention specifically Wuhan, NYC, and Italy as examples.

Might also be worth mentioning that in the 1918 pandemic the first wave broke records, made the news, encourages changes like social distancing and masks. But it was the second wave that was worse, caused by opening up things to quickly.
Eh, I wouldn't lean on it that much. Yes, a significant factor, but activism or its appearance is in many ways more an effect of finding and cultivating an audience and optimizing for their attention, and ultimately things like advertising dollars and social media likes and such.

I think there is this insidious link between people's opinions and "biased" news coverage where they are both spontaneously emerging and evolving and in effect causing one another specifically not being driven by an external activist idealism but emerging from the motivation to make money and get attention - which I think is much more dangerous and scary than if the news was being driven by some intentional agenda. Like it's this organism or disease which is evolving to take maximum advantage of human weaknesses, on one side of the publisher for the needs and rewards of money and approval, on the side of the consumer for what grabs attentions, builds loyalty, and shapes opinions. It's this monster that is shaping the human world out of control.

It is also possible that it is 2am and I have been watching too much Ghost in the Shell.

Interesting. I guess it only applies to monetized content, otherwise, I can't think of a more clearer case of antitrust with YouTube, given their monopoly on internet videos.
Also had a very bad experience with O2. I switched back to T-Mobile it's expensive but at least someone will answer the phone.
"Growing anomalies at the Large Hadron Collider" sounds like a premise for a Hollywood horror movie about a strange, shimmering anomaly growing at a science lab.
Yes, indeed I took the average age of the mother of any birth and not the average age for the birth of the First child.

Official Italian ISTAT report for claims 31.1 for mother age at first birth. Still significantly higher than US fwiw.
I do, but that's irrelevant to the fact the corporate funded research is used to muddy the waters and make reality even less accessible than it is.

It's not the lack of research that's a problem, it's the weaponization of research.
I could be wrong, but seems like a pipeline is extremely hard to build, with lots of volume of material, concrete or steel. It seems lighter and easier to build an HV electric line. I see HV lines everywhere, but very few pipelines.

Also, pipeline operations (leakage etc) seem a PITA.

That was my idea behind thinking electricity is easier.

However, the sheer ratio {transport energy} / {transported energy} is indeed in favor of pipeline, as you mentionned.

--

I found that you can bury HV lines:
https://retasite.wordpress.com/burying-high-voltage-lines/

I found that it costs between $2.9 million and $13 million per mile to build a new pipeline, whereas it costs $285,000 per mile for a HV line and $1.5 million per mile if you build it underground.
> Sybase SQL for a project these days. It's legacy tech.

1) SQL Anywhere is not "Sybase SQL." Different products, with SQL Anywhere being an embedded database that can run on a smartphone and replicate bidirectionally to other masters.

Not many alternatives, even in 2020.

2) Legacy tech - when you care about your data, accept nothing less.

Fun fact: the #1 most popular and regarded RDBMS for the past few years is considered to be MySQL, and it was the key technology that powered both Web 1.0 and 2.0. If that's legacy, I want more legacy.

David Lynch truly is the most successful troll of all time, ironically achieving artistic depths through deliberate obfuscation and random ramblings.

I think it says far more about people, and what they are willing to accept as profound (or unwilling to discard as meaningless), than about David Lynch.
Ask HN: Any job boards and age-friendly companies for older developers?
I've spent last year interviewing only to find out that I'm considered too old (I'm 45) for most shops around. They won't spit it out directly of course but people talk and what they say is that I need to be stellar or young to be hired. Companies won't invest in me the slightest bit, so the moment I miss a question in the long interview process I'm out of the door without second thought.

So...

1. I might be banging the wrong doors. E.g. FAANGs don't seem to be right. Any companies that don't drink/sell the youth cool-aid?

2. I might be searching at the wrong job boards. Any suggestions welcome.

3. Finally I might be better doing sth else altogether (but what?) rather than fighting a loosing battle against preconceptions that run so deep.

Anyway. Thanks for any non-insulting answers in advance.

PS: I'm based in EU and I'm a SW Dev working mainly in DevOps and Reliability.
Meaning? Can you elaborate a bit? I’ve just downgraded to Mojave on an iMac (fusion drive) primarily used for Logic Pro.
Do you think Mojave is not getting updates anymore ?
Read a user somewhere reporting that leaving his iPhone plugged into his Mac caused this problem to occur almost daily. After charging it with a wall charger, and not having it plugged in, the problem went away. After resetting PRAM and SMC too. Hope the issue gets resolved for you someday!

I would like the Elixir without the Erlang.

I would like the Python with some pipe forwarding.

I would like the Python as a binary.

I would like the package management of Rust.

The DMCA is supposed to have protections against malicious use, but it's clear that those protections do not work.

This is remarkable:

> “We’ve seen lots of examples of people sending D.M.C.A. notices when it’s pretty obvious that they didn’t think there was copyright infringement,” said Mitch Stoltz, a senior staff attorney for the Electronic Frontier Foundation, a nonprofit digital rights group. “There’s not much accountability.”

> On May 21, the U.S. Copyright Office released a report detailing how the 22-year-old D.M.C.A. has failed to keep pace with the anarchic digital ecosystem, as online platforms have been overwhelmed by a crushing volume of takedown notices. Between 1998 and 2010, Google received fewer than three million such notices; in 2017, the company got more than 880 million — an increase of more than 29,000 percent, according to the report. Many requests are legitimate, but the report notes that other motives include “anti-competitive purposes, to harass a platform or consumer, or to try and chill speech that the rightsholder does not like.”

This is an algorithmic arms-race between the bots that find "infringing" content and send takedown messages, and the bots that respond to those takedown messages.

What is really nice about this is that they show response to actual human samples, not just purified spike protein vs. control proteins/blanco buffer controls. This gives me hope that a finalized test could have good specificity...

Finally, clinical samples were tested to analyze the performance of the biosensor. Human swab samples from a normal person and a COVID-19 patient were collected separately. The normal sample was loaded onto the device before the addition of the patient sample. Figure 3a clearly shows that patient samples produce a different signal from the normal sample within a couple of minutes. Even after diluting the patient sample 100000 times, clear responses were observed.
The happy range for a modern battery is 20-80%.

The bottom and top 20% are what's causing the wear, so merely staying between 90% and 100% won't do you any good.

Another solid alternative is Realm. We have used it for several projects, and the experience was light years ahead of Firebase.

This looks like a good tool, but it took me a while to find the demo video to work out what the product actually is.

Now list these on your homepage with big screenshots or a quick video (no more than 30s seconds) to show people how great your software is.
There is obviously different rules for big Hollywood players vs small youtubers, since YouTube also sells their movies in VOD, if you know what I mean. I mean that's already the case regarding copyright strikes where big corps, music labels and Hollywood can abuse the YouTube copyright system without any repercussion whatsoever. All YouTube channels aren't equal.

Bacteria and fungus could reproduce inside a web mask, moisture and a source of food (spit, sugar, mucus, protein, or similar) is enough. Virus however need targeted cells to invade and take over the cell mechanisms to reproduce the virus. Said target cells for COVID19 are unlikely to be reproducing in your mask.

So buy (or make) 2 masks, use them on alternate days, and make sure they dry out completely between uses. If particularly scared/careful wash and dry them between uses.

We know about all the ones that matter though. Like the keystones of the ecosystems.
OK, attempt at ELI5:

The people are crashing lots of bunches of pebbles into each other, in two streams that meet.

Some of the people are interested in observing what happens when the small blue pebble hits a big gray pebble and the big one cracks. They know the "probability" (cross-section) of this process is around 100 fb.

Other people care about what happens when little tiny green pebbles collide three at a time. They know the "probability" of this is 11 fb - not so likely since three things need to line up.

The people operating the streams of pebbles keep track of how many inverse fb they produce. Let's say in 2019 they produced 0.7 inverse fb.

Then the people who care about blue/gray collisions know they can expect to find around 70 events in all the data from 2019, while the green/green/green people know they can expect about 7-8 events.

When the people who collide streams of pebbles are going to build yet another Even Bigger Pebble Crashing Machine, they estimate in advance what the "luminosity" will be - how many inverse fb they will produce per year. Then the people looking for events know, "aha, with the new great crasher I can science even more!"
Btw does anyone know how to test-install a newer OS other than with Mac OS' upgrade option burning through 6gb+ downloads supposedly also replacing the OS rather than installing it onto an external disk? I've got an unused old mini that's still on the OS it came with - way out of date. I even went to an Apple dealer to get Mojave onto an SSD drive last year, only to find out that the mini needs a firmware update for APFS that only comes with Mojave/Catalina, but I can't find a download option for only the firmware update so that I could boot from an external AFPS disk.
I'm not discounting that this was an annoying ordeal for this channel to go through, but if this is so easy, why don't professional criminals go after huge channels and take them down as easily?

There might be some subscriber count threshold or partner status that, once crossed, flags extra steps that mean a new violation is escalated for a closer look first?
Do you discharge your iPhone all the way to 0%? The bottom 20% are also not so great for battery wear.

Ideally you would stay between 20-80% (only charging to 100% and discharging to 0% when you really need it)
Is this sort of thing not pretty normal for basically all business writing? It's meant to get traffic inside echo chambers like LinkedIn, not actually help people.
Where are the models that predict how many people will have long term disabilities due to COVID-19? And another set of models that predict economic damage (in a variety of areas and dimensions) due to deaths and disabilities and shutdowns? The virus causes much more damage than just deaths, both human and economic, and it would be useful to have a picture of the total cost in multiple dimensions. In particular though, no one seems to have any idea currently how much disability is being caused, which seems like a very important thing to understand. I would have thought that epidemiologists would already understand this and would have had models ready to go for both the disability and economic aspects. There are probably other dimensions that could be modeled also, such as disruption to transportation, effects on climate, effects on wild life, effects on insects, effects on rodents, effects on agriculture, etc. Modeling just new cases and deaths provides a really limited view of what is going on.

Some dimensions might be tough to model in advance, especially if they depend on the specific characteristics of the disease, but we have some historical examples to work with. Maybe a higher level approach would help, build a model generator that produces models tailored to the specific aspects of a disease. Or create a set of building blocks that can be connected to create a tailored model.
They did adapt the models to predict number of ICU beds and ventilators needed, but the modeling of the repercussions of a pandemic seems to be lacking. Perhaps corporations are doing their own modeling (almost certainly) but the public needs this information too.

Edited to add: I did find this economic forecast, which isn't a model, just a sampling of opinions of economists:

To use 60% less fuel, the car needs to havee appropriately less mass, so you are talking about 700kg for a 5 seated car with passengers.
If you are talking about fossil fuel cars with regenerative breaking, you are talking about hybrids, which use their electric part for that, but their breaking power is limited compare to pure EVs by the electric engine power and the charging limits of the smaller battery.
I just want to add, because some people might find it interesting, that a version of the fast Fourier transform was already known to Gauss (though not published in his lifetime). More info can be found in the article "Gauss and the history of the fast Fourier transform" by T. Michael.
Yeah I googled around a bit and found not much evidence. I currently theorise a bit that you can run a little without padding to learn that running style but then go back to normal shoes and try to keep it up. Not quite sure myself.

A lot of complaints here, but no actual substance.
