I understand this, but at the same time, cyclist-pedestrian collisions also contribute to the public's resentment towards cyclists. I'm not sure which is worse, an admittedly small chance of hitting a pedestrian or annoying them with my music for 2-3 seconds. On the balance of my safety as I have unfortunately come close to such accidents many times, the choice is not so hard.

I'd like to emphasize that the music is not that loud - when I'm close to a car I can barely hear it.

I worked at a place (briefly) where the CI process was pulling down 3-4GiB of container images for every run. Same repos, same sites, every check-in on every branch pushed to GitHub set up a blank environment and pulled everything down afresh. Then the build process yoinked dozens of packages, again with no cache. It must have consumed terabytes a day. Madness!
I doubt it. E.g. the headline "New gravitational wave detector picks up possible signal" (1) does not imply intent, just measuring a definite event and not just noise.

Nobody has a time machine that lets us go back and fix things when they were fixable.

If this company never existed, most of these wells should have been permanently shut down long ago. The owners didn't have the money to do it, so the states were supposed to do it. They didn't have the money either, so they weren't doing their duty.

Along comes this guy, who offers plausible deniability and creative accounting, and the states get to delay spending the money they were always going to have to spend. In exchange, this guy gets to collect tax incentives that make his business viable. Who would voluntarily become the scapegoat if it weren't lucrative?

Meanwhile, the planet burns.
Is there some kind of a study that people can use to benchmark their finance textbook remembering ability? Because after factoring in a small amount of exaggeration in "might as well not have read it," forgetting a substantial fraction of a million facts, all of which the reader found boring, after two months with no reinforcement, sounds kind of plausible.

Indeed there are many flaws. One loses 15% per year in value; the other gains >100% per year. You don’t need interest payments on Bitcoin for it to be economical to hold. It seems so foolish to risk such returns for a measly few percent on such an asset class. I think it’s some kind of greed test.
Ideally you want some atomic deployment strategy, rather than having to deal with whatever crap might have been in the directory previously. Something like - extract your deployment artefact to a new, unique directory - and then read-only bind-mount that directory as /var/www/html.

> and probably very stupid) method is an Expect script that lets me supply a password to sudo.

The old school sysadmin way of doing this would be to have a dedicated deployment user (ssh pubkey auth only - possibly restricting only specific commands), with a sudoers[.d] configuration to allow that user to run an explicit group commands without a password (NOPASSWD)
The thing with college towns is that you tend to have the campus and, if it's in a rural area, generally a few streets of associated town. Technically walkable but, once you're not a student any longer, the campus is less interesting/useful and there probably isn't a whole lot in the ten or so blocks of the town that you can walk to. You can doubtless survive but the options are probably limited without a car (and most of your non-student friends in the area probably have one).
We'll be vaccinating our young kids as soon as FDA provides EUA. If it's approved then it's safer than doing nothing in their age group. The risks of infection with no vax, vaccinated infection, or reinfection ("natural immunity") are all tiny in kids; we're more interested in protecting the grownups they spend their time around.

One angle that I don't see discussed a lot is what parents will plan to do if ACIP doesn't recommend any SARS-CoV-2 vaccine for very young kids (i.e. not until they're 5+ or maybe even 12+). It's very possible they could find the tiny risks from vaccination outweigh the tiny risks from infection.

There could in principle be an interesting moral question. If vaccinating very young kids is almost but not quite harmless -- like it raises their risk of mortality from the equivalent of driving 100 road miles to driving 110 road miles -- but it dramatically reduces the risk that their adult caregivers will die, should they be vaccinated? If ACIP ends up looking at the data and saying that vaccinating the youngest kids is worse I don't think I'll be giving them a non-approved vaccine. I can see why people would do it, though; the magnitude of the risks could be similar to those incurred with air travel as a lap infant vs. being secured in a carseat.

The latex example did not run entirely on Lambda. Lambda would write a job into a queue (just Postgres), trigger a launch of a beefy ec2 instance, after which a worker on that ec2 picked up the job. Another lambda function would be called by the server itself to shut down the worker when all jobs were done.

Kludgy and slow. But it worked and did save some money, because the instance running this latex worker was big and chunky yet utilized maybe 10 hours a month.

Lambda was mostly acting as a kldugy load-balancer really.
I study by writing a summary of the material that I'm studying. If the material is very comprehensive I do a summary of the summary. The shortest summary is the only material that I review before the exam. For example, if I had to study a whole book, I would write a long summary first, and then a second, shorter one. This technique works because first you have to go through all the material and understand it, and second everything you write down tends to be remembered much better than if you just read it.

Agreed. They should have just sold ads for the unpaid edition users to tolerate.
a pattern I have seen before is to clone the branch commit of each release to a folder /var/releases/{release_commit} and then html is not a folder but a soft link so /var/www/html -> /var/releases/latest_release_commit
this is useful if you need to revert back quickly.
But then releases folder needs to be cleaned up, or you can run out of space.

This happened to me about an hour ago. Suddenly my machine started restarting. No notice. No ability to stop it. Anything running was forced closed.

How would you know it occurred? The approval system for this is secret. It would require that Signals actively come forward and say that they did this, when some other government body finds the material and charges you with a crime.

You would need to both know it happened, and be able to prove it happened, and the usual targets for something like this (journalists) can usually only suspect the former at most.

As others have said, try to avoid any kind of DevOps if you can. But here's my strategy:

Monitoring - Loads of cron jobs pinging slack (monitoring disk, CPU, Network I/O etc), Healthchecks.io, TurboAPI, Nginx Amplify. Mostly built up over time

DB - Done entirely via migrations. Most of the time they are small migrations so I can do it by running the command directly on the instance

Deployments - GitHub actions to build a docker image (there was a prebuilt template). Watchtower then runs on my server to pick up the new image and that's then deployed automatically. There is no rollback system as I've not needed that so far (and 99% of the time you won't).

Backups - DB backup is done via a cron pushing to AWS S3 Glacier. The app code is stored on GitHub already so no need to back that up. Happy to share the script if you like :)
Yeah I could see serverless being useful for those scenarios.

First, I don't think your comment is relevant to this discussion, but I guess that has never stopped anyone on HN. People complain about Apple maps, and the article is about how much work Apple is doing to improve their maps.

As to many of your other points, they are just wrong. I do repair my own devices, I do install my own software and I do run my business unfettered. I can't speak for others, but your assertion is not consistent with my own experience.

Which files do they "spy" on? They do offer on-device services like automatic photo tagging, rule based email filtering, etc. I can use those or not. I can grep and search my files, so I guess Apple (the OS) is "looking" at my files. Is that different than any OS? Basically any OS vendor has access to your files. You either trust it or you don't. Apple's business model is not built on selling my data to advertisers so I choose to trust them. You are welcome to make another choice.

As far as coddling to authoritarian governments, yes they follow the laws of the countries they operate in. So do any other companies that operate in those countries. That stinks, but that is the reality. Companies can either abandon markets or follow local laws. Which of these is the long term good? Lots of valid arguments both ways, but there can be no argument on one point. Operating in country X requires following the laws of country X.

Look, they are no saints, I get that. But they build great devices that do everything I want them to do. Of course there are people that have bad experiences, but overall Apple's customer satisfaction numbers are extremely high and people keep buying their devices. That's not an opinion.

To your central point, yes, as Apple offers more services that I find useful they do accrue more power. Which large companies that offer useful services do not accrue associated power? I choose to align with the company whose business model is not built upon selling me and my data to third parties. Eyes wide open. There are other good choices and I am happy for other people to make different choices. I don't feel pain for them.
I think the mad 4 processor 3DFX Voodoo 5 6000 that was never released used an external power supply, at least on some PCB revisions.

I'm not sure if any released graphics card has used their own power supplies. I think they all used some sort of internal connection to the standard power supply if the slot can't power it alone.
This is a nitpick; but the first example doesn't make sense once we use ReadOnly, because it doesn't return the copied+sorted array. So in practice the final version of sortNumbers would have no effect afaik.
That's just burst concurrency. It takes a lot longer that 1 second to actually reach the peak burstable limit. So while the Lambdas are scaling up your clients are either waiting several seconds, or getting 429s.
We can split hairs about which one wanes fastest, but it's not like vaccine provided immunity is bullet-proof or lasts forever: As of 10/4, COVID19 cases resulting in death or requiring hospitalization are up to 1/10,000 among the fully vaccinated and the trend has been going in the wrong direction for a while.

When I first read about the NTK I was motivated to try an experiment to see if the kernel depended on where in the parameter space one evaluated it. I was surprised to see in my simple example the answer was "no". Here is a write up I did:

I would encourage people to get vaccinated if they can, however we don't have strong evidence that this will reduce the risk of more dangerous variants. Vaccinated people can still get infected. They may clear the infection a little faster on average but the reduction is limited and temporary.

https://www.nature.com/articles/d41586-021-02689-y

Immunocompromised patients are a more likely source of new variants. They can suffer persistent infections giving the virus much more opportunity to evolve. Vaccination is less effective in such patients.

https://www.nejm.org/doi/full/10.1056/NEJMsb2104756

The Delta variant is already so infectious that it's probably already close to a local evolutionary maximum. Measles has a higher R0 but it's genetically very different.

There are 4 other endemic human coronaviruses including HCoV-OC43, another beta coronavirus very similar to SARS-CoV-2. It probably caused a worldwide pandemic that killed a lot of people in 1889, and still frequently kills frail elderly patients today. We don't have a vaccine for it and most of us probably get infected at some point in our lives. Yet even though it's had over a century to evolve it hasn't become dangerous to youths.

I am trying to solve this particular issue in online learning. You may read a lot of books and watch quite a number of videos, but after few weeks or months, you remember zilch. Things are different when you are learning and applying, for instance, trying out a new framework or programming langauge library. However, most of the things are not really straightforward to "apply and understand".

You are always going to forget, no matter what. The real question is can you recover (faster) and retrace whatever you have learned. Think about stuffs you read up in high school or universities or colleges. How much of it is you can recollect? Can you "recover" what you have learned and "resume" from the point you left?

My solution is creating a conversational learning medium. Users are forced to respond to write their own inputs and observations. These inputs then act as "memory breadcrumbs" for you to retrace when you again come back later on. And then you can resume or update your mental models/abstractions about the topic.

I have written a comics-based essay on this topic: https://primerlabs.io/comics/memory-breadcrumbs-comics/

It took time for me to get it right, because of my perfectionism issues. There are two free courses right now: Python-I and Fundamentals of Computing.

The features of the platform are:

- Automatically generates flashcards which you can export as Anki

- Generate a personalized Book after completion

- Retrace Mode to retrace whatever you have learned

If anyone wants to try out conversational learning medium, you can use it at https://primerlabs.io/ ( No Signup Required Whatsoever).
Right on, I really appreciate it.
Here's an alternative approach, that actually provides real world results

https://calculatedcontent.com/2019/12/03/towards-a-new-theor...

Using techniques from statistical mechanics and strongly correlated systems, we can compute the average-case-behavior of a real world DNN

We believe we can reproduce some of the results of the NTK by using a Gaussian Random Matrix. But if we use a more realistic, heavy tailed matrix, we get more practical results

A early fork of the theory has been published in JMLR
https://arxiv.org/abs/1810.01075

and the empirical results in Nature Communications
https://www.nature.com/articles/s41467-021-24025-8

and we have an open source tool , weightwatcher, which can be used in production

pip install weightwatcher

> I don’t really see much customer or Apple benefit for them to give away control over software distribution on their platform.

You don't see it because it's not allowed to be seen. All those things which can't produce with a 30% margin to give away to Apple don't get to exist. All those things that want to use something Apple doesn't allow are not allowed to exist. All those apps which are denied in review for obscure reasons don't get to exist.

> Pretty much all discussions and Epic’s court case is not about customers, it’s about giving less to Apple and keeping more to themselves. That’s it.

For the users supporting Epic and wanting to pay Epic for what they've done, it's about using your own phone as you please. Apple wants to get paid 30% to not veto apps.
Have your runWarm sleep for 500ms and execute 50 of them concurrently. As long as none of the functions are finished and you start a new one you get a new instance, at least that's what I think.

You can get 50 hot instances that way no?

I'd rather scale per connections. Have a lambda instance do 50 concurrent requests. Something like https://fly.io but cheaper.
BTW, Boston did pretty much bulldoze the center of the city (the West End) for a freeway but spent some $10 billion (much of it federal money) to rectify the problem with the Big Dig. It was walkable before the freeway was dismantled but less so in Boston proper. (As with other US cities, it was also less safe in general a few decades ago.)

Lambda only has default support for the LTS releases of .NET, which is 2.1, 3.1 and the upcoming (November 2021) .NET 6.

The only way to run .NET 5 in a Lambda that I know of would be custom runtimes or containers. Is that what do you mean by “switched to using Docker images”?

This article describes the containerized performance of .NET in Lambda and the cold starts are dramatically (~4x) worse.

Writing it down helps some, but for specifics, it's better to remember the shape of the information and where to find the answer, than the answer itself.
Pricing-wise, currently it's free, and we'll make sure there's a full-featured free tier if/when we introduce paid plans. The current plan is the have usage-based pricing i.e. a certain amount of sessions per month, but we'll be surveying our users to set appropriate tiers and price points :)

We experimented with live sessions but weren't happy it was real-time enough to be more meaningful than after a short time delay, it's in our backlog to revisit when we can spend time on performance though!

At the moment it's not set to be triggered for specific sessions, none of our early users have requested that but it would be pretty easy for us to implement :) At the moment we're letting our most engaged users take a very active role in determining what comes next e.g. we rolled out IP screening (all happens client-side) and email/domain name screening yesterday as per a request we received yesterday morning. If you sign up we could get triggered recordings in for you super fast ;)

No open API access, we have discussed it though. Recording link sharing with private, or public links, and mp4 and gif (snippets) export is next up.
