I took an online class in high school. They told me it was the first ever such class taken for credit in the US. It was pretty bad, but I didn’t expect much. It’s easier to learn the answers this way, but much harder to ask the questions. As an adult looking back on who in my class became a teacher, I also realize that teachers in general are usually not the people you most want your kids learning from. Not the worst though. Curriculum is mostly just a vehicle for inquiry, and should be treated as such. Expect no results from this online platform. The kids will get the material done just fine, but they won’t engage with it unless you make it relevant to their imagination. Maybe it’s not that important though. Maybe they should be interested in other things.
You might have a look at the O'Reilly book from August 2, 2017: "Test-Driven Development with Python: Obey the Testing Goat: Using Django, Selenium, and JavaScript" 2nd Edition
Yeah, I want that, but not chess :)

I prefer games that have a randomness element.
I think I need to repeat this:

I'm sorry, what? Do you have a response, or only ad hominem attacks?
Yup, it will be a mess and we need to come up with solutions. But we shouldn't let that influence the decision.
> For every Beatles there was 10 Monkees.

Hey, wait a minute! The Monkees were pretty good for what they were (mass-production pop) — at least in the early days when they were doing Boyce & Hart compositions.
The problem with the English Rule is that it protects the rich.
It is hard to disagree with Mr. Stallman on this. But while it seems to make sense to protect privacy, whistleblowers, etc. (http://lukecall.net/e-9223372036854639582.html), doing what we can, it is not clear to me that there is a critical mass of those who believe in the Golden Rule, for this to be an adequate solution.

So, it seems that we need to make sure the lights shine as brightly in both (all?) directions: on all those with power, as much as on those about whom they gather data. Other suggestions welcome.

And, I believe in prophecies about these last days that say things will be in commotion, etc. But we can be OK. (http://lukecall.net/e-9223372036854588519.html for example).
I actually prefer web apps because browsers make it easy to view control what’s being sent over my network. Requests are decrypted in the browser and can be viewed in plaintext with the browser console. They can be blocked using tools such as uBlock Origin.

Standalone client-server apps have full, unsandboxed control of your computer. It’s impossible to see the content of encrypted network requests, short of hacking into the app. See: Wacom’s drivers track the name of every application that you open:

Without reading: I think that the importance is that before we had methods that could do that. Now we know that there is an algorithm that can do that. They proved that it is always possible, not in some subset of the networks.

In the other hand, it will trigger research on reducing the size of the networks. That is important, as most researchers don't have access to the computing power of Google and the like.
There are plenty of careers that have math as it's base subject. Research what else you might like to get into and move forward on that. Getting a job in academia is already hard so adding the violation will make it impossible. You need to come to grips with that and move on to something else. If you're lucky you might even get a research job in the private sectors. You have a bright future you just have to switch your goals a bit.
My understanding was that the location and arrangement of peripheral nerves in the human body is not fixed. So which parts go where is not identical. But yes, supposedly you can relearn.

I cut the shit out of my thumb a few years ago and was relieved that I could still feel everything, except for one little spot below the cut (which also pooled blood for a while, both issues have resolved now) I’d heard that it’s a crap shoot whether you hit the nerve or not, and none of the three doctors I talked to disagreed with me.
You’re time period is very convenient, including two crashes and none of the recovery. That said, point taken.

That sounds a lot like the basic idea behind Terry Pratchett's Discworld.
With everything going on, it is more important than ever to have purpose and direction in life. For one thing, it lets one freely & more peacefully ignore many things in popular culture, because they are irrelevant or unhelpful, and focus more on things that matter, intentionally chosen. My detailed thoughts on that, whether religious or not (no sales or JS) are at: http://lukecall.net/e-9223372036854588981.html
Scaleway gives you a k8s cluster starting from 40 EUR per month
Great! But you seem to be the one who’s confused. I was commenting on semantics. The “illegal porn” being referenced above is not porn. It is abuse.

Carry on with your discussion of why backdooring encryption is bad. I wasn’t commenting on that matter. This entire thread has no real discussion of how to solve the “encryption-while-scanning problem.” With the massive growth in CSAM sharing in the last few years, enabled by easy to use services like facebook and dropbox, it’s clear that solving this dilemma is just as important as protecting some normal person’s ability to use TOR. I’m extremely privacy focused, but I’m curious to learn if crippling fb/dropbox/etc is worth it for the sake of solving this issue.

Also, “traffic accidents” isn’t preferred, either! Do you hate me now? Language is important. I’m a transportation planner who focuses on safety, so I can talk about this all day.

Ask HN: What is impact of Oracle lawsuits on alternative implementations?
Now that Oracle claimed Google is infringing the copyright on their APIs, how will the situation affect alternative implementations?

I think you’re onto something. It takes time to get used to public speaking and even when you’re moderately good at it, there’s always some initial anxiety and nervousness.

If the point of demo day is to explain your idea in an efficient and understandable way, it seems like video would be the way to go.

I think there’s a lot of benefits to meeting in-person, some of which are hidden and you can’t anticipate. A lot of deals have probably been done due to serendipity and chance in the hallways so I wouldn’t want to discount them entirely.

But I like this. It feels like at the very least, there’s an opportunity to experiment with something new.
Yes, it's the only supported "add-on", it's preinstalled and cannot be removed. It's like the people in charge don't even know what an add-on is.
The following is a simplification but should suffice.

Airflow is for hooking together and managing a bunch of data sources, data-processing nodes, and data sinks.

This project seems like a GUI for Scrapy, which is a web crawling framework, i.e. one kind of data source.
Is it fair to say that one reason the bond market is so large is because of capacity and simplicity?

The impression I get is that when you start talking in terms of $x0M+ US regular investment (e.g. on Monday, then again on Tuesday) stocks become a less viable option (due to liquidity and risk of orders moving the market).

Bonds also seem more simplified and standardized, in that there are fewer weird / unmodelable features in a given bond issue.
Ask HN: The strange phenomenon of stockpiling ‘toilet paper’
Are people afraid that they will shit themselves to death? In that case, shouldn’t they be buying meds rather than stockpiling for untreated diarrhea? Is this a first world problem?
That assumes that there's one linear cultural progression and America is simply a younger version of Europe. I don't think that's necessarily true. It could be that America is on a different cultural arc entirely, driven by differing fundamentals (land vs population, history, economy, etc).

Americans have thought similarly about Asia for awhile now, the thought being that Japan, then Singapore, then China, would adopt more American beliefs about free speech and freedom of the press. That hasn't quite happened to this day. I don't think it would ever happen unless the fundamentals change.

An analogy: The snow fox tells the forest fox that red fur is a liability, and you should have white fur like me to stay safe.
You're right, it would be a shame if the police had to face any sort of retaliation for blowing up people's houses. If we ban guns they can blow up everyone's house without fear!

If they don’t, then you’ll have an increase in $1999 crimes. Look at the effect of Prop 47 in California. Crime has increased.
Funny, when I first read this, I thought of school closures in public districts where budget concerns are forcing long-term, permanent closures, not temporary ones due to CoVID-19. Maybe I live in a bubble?

I live in the Bay Area now and reading this thread makes me miss Seattle (lived there 2009-2011). It's one of the better cities in a pretty well-run state, with funded pensions, responsive politics that seem more resistant to special-interest capture (unions, ultra-rich), and a well-informed populace and leaders capable of doing the right thing.

Oakland, by way of comparison (where I live now) regularly has school board meetings that get shouted down by angry mobs (https://www.kqed.org/news/11781890/parent-protests-against-s...), a school district with a chronic major deficits (https://www.nbcbayarea.com/news/local/budget-deficit-forces-...) and accounting scandals (https://www.sfchronicle.com/bayarea/article/Oakland-schools-...), and unsurprisingly, striking teachers are demanding even higher pay in the face of all this. With such gross mismanagement and leadership without the backbone to address it, it feels almost unconscionable that I'd let my kids attend this school.

I'm not sure what to make of this other than that, if you live in an area with a healthy political culture, be thankful for it. And if you don't, pay attention, and get involved.
I think my comment got lost because I can’t find it, but I said something like: maybe we need a formal macroassembler for IPC/RPC calls instead of running “code” directly in the kernel.
>The current market turmoil is mere noise in the long term.

Which is exactly my point.

Interest rates could skyrocket to 20% or more for yet another unknown unknown financial black swan event.

Or your home could be worth 25% of what it is today before you know it.

The ground could literally open up beneath your house and swallow it hole, leaving you with nothing but that massive debt obligation. (As most home insurance plans do not cover acts of god like sink holes).

That's an insanely rare and extreme example, but I hope you get my point.

It's best to get out while the getting-out is good.

If you have a large debt obligation that your current home value can pay off right now and then some, get rid of that debt and create some real wealth.

You've officially won the game of middle-class life at that point.

Then you can dream about what to do with that wealth until the cows come home... once you're actually wealthy and have the time and money to theorize how to properly invest that wealth.
Caused 670,000 to uphold the law and prevent us from inching that much closer to anarchy. That's the invisible benefit to most. Soon as criminals can figure out the law enforcement's cost-benefit ratio, they will start exploiting it, and there's too many examples of this to count.
Only Azure doesn’t charge for the k8s control plane, that is the most surprising thing for me.
Wild guess here but fatality rate is based on the number of dead and the number of reported cases. High fatality rate means either high number of dead, or low number of reported cases. Knowing the real number of infected is really hard, especially in population less at risk (the young and healthy).

For example, there was this anecdote this week about a woman in the US. She believes she's infected, but none of the responsible authorities will let her pass a test unless she's physically been to one of the high-risk countries. So she either self-quarantine or ignore all of it and go to work. The twist is that she's a health practitioner...

This is why you never read stories about a man running a sewage treatment system from his garage.
Yeah, though this feels artificially slow to me. Even the earliest Teletype machines could manage 10+ cps, and by the mid-70's time frame (v6 was released in 1975) much faster devices were available (and of course video terminals were starting to arrive too).

I'm sure someone used a PDP-11 with a terminal this slow, but it's unlikely to have been the typical developer experience.
There is also arms race between police and criminals who can run grams of steroid and look more jacked. Steroid use is very common in police
> Bond yields should be less than S&P dividend rates

No. Stocks don’t necessarily pay out any dividends at all, like google or amazon. Stocks can also give substantial capital gains. Bonds have historically had higher yields than the dividend yield of the S&P to entice people to purchase them to compete with this fact.

While they have a higher chance of getting your principal back they also have to compete with other assets for the money. This is why bond yields typically go up during “good” times as people feel the stock market is a better place, but the yields then go down (for “safer” bonds at least, like the federal government or high rated corporations) as people flock to safety and the demand means they can pay out less.

This is news because it’s another indication that people are flocking to “safety” causing both the bond yields to go down due to demand, and the stock yields to go up as their prices fall.
Personally I don't have any problem with geofenced warrants. I actually think they are a pretty great idea. So I would more say that he spent $2000 pointlessly. What would likely have happened if he hadn't fought it is the prosecutors would have gotten the data, seen who he was, and been like, nah, not our guy. They don't just go and arrest every single person who has been in a geofenced region when they get these warrants. They use it to look for who might be worth additional investigation.
Ad "Zettelkasten" and how you "converse" with it (that's how I [mis]understood it):

Luhmann started out by doing these things:

* He had sequ. numbered cards, that were written on until they were full and therefore could contain multiple topics - and one topic could therefore also be on multiple cards (no. 1,7,15), if he later added to it

* He had a topic index to map card numbers to topics

* Most important: he used this system with slight variations continuously over years and it was a one person system

The benefit (that you can get with a personal wiki too, if you follow the system with Plugins) is, that when you get all cards on a topic, you also get the information on the topic you wrote down right before and after thinking about the topic you are researching...

As information organisation and knowledge is a personal thing, retrieving info from the cards with the other topics you thought of right before and after, might lead to subconscious connections that

- and here is the "conversation" -

then lead to your brain making connections that go beyond what you wrote down on the cards... at least that is how Luhmann described it... could anyone follow my little mental jump session?
For some purposes, I wonder if OpenBSD would also be a strong candidate for learning about operating systems, given their focus on correctness, openness, portability, etc., and the fact that everything learned then becomes useful on a fully general-purpose OS that one could use in the long term (ie, lots of headroom, less need to start over for learning some things, somewhere else).

The quality and good order of the documentation in particular makes it less or not necessary to go doing web searches etc to find out how to do things, but they take one in an orderly progression from installation, via FAQs and excellent manual pages, all the way along to useful development info.
I'd recommend the book Maximum Willpower, by Dr Kelly McGonigal.

It busts a few myths that are also prevalent from many other motivational books by non-psychologists. WFH is really where many of those start to fall apart.

Like stress is actually destructive to willpower, one triggers your physiology to fight, the other gets it to be calm and in control. Simple techniques to train willpower. How to manipulate your fight-or-flight response into self-control (similar to how we balk at prices but shopaholics don't). How pressuring, rewarding, and guilting yourself makes things worse. It's easy to fall into these traps from home, and then go down a spiral of bad advice which makes things worse.
I doubt a a 65-year-old teacher needs any more confirmation.
So the US helped fund this in 2011. And now they won’t buy more because Israel refuses to supply the source code. As far as I know the US does not supply the source code of the Patriot batteries to foreign customers as well. So this should be no surprise even if it was partially funded by the Obama administration. Or maybe they are just bad at making deals.
Ultimately, correlation in free markets is just frequency of similar participant behavior, no?

So if everyone is using robo advisor allocation, and the allocation algorithms all feature a similar bond shift, then that becomes the correlation?

Buybacks directly cause dividend yields to go up because they reduce the number of outstanding shares, causing the remaining shareholders to receive a greater stake when future profits are distributed amongst fewer parties.

It's a quality of life thing. People think you only need to stockpile food. Obviously, it's better to have food than to starve. But there are also important psychological aspects: if the Internet goes out, what are you going to do all day?

Thus, it's important to stockpile "luxuries": board games, toilet paper, candy, etc.

And the same statement says those 50 and over should basically stay home. I'm sure that a significant % of school staff fall into that grouping.

In regards to the quote, absence of evidence is not evidence of absence.
I doubt very much that these online days will count towards the minimum allocation of school attendance days. That means lots of children might need to repeat a year due to the gaps. Online courses are no substitute for real schooling as they are all lousy. Interaction is woeful and teenage children certainly don't have self-direction as a majority.
The third book of the Three Body Problem is pretty amazing to read if you like sci-fi which goes to the heat death of the universe.
From my experience the greatest optimization gains can be achieved by introducing more domain knowledge into the code. Heuristics that cut the number of executions of some expensive function, shortcuts that introduce good enough approximations, pre-computing and memoizing certain values that are actually constant in the processed data. Things like that.

And in programs that had never been optimized it's usually very easy to fire up the profiler and find some obviously terrible things. Like reinitializing in a tight loop some expensive object that can easily be a singleton (or at least a thread local object). I've once spent a month on a decent piece of code and brought down the CPU cost by literally 100x (nobody had optimized the code before).

Also, always, first create a reliable framework for measuring progress (cpu instruction retired counters in Intel CPUs are very good and don't need a lot of execution repetitions to bring the p-values low), and only then start optimizing.

Low-level, hardcore optimization rarely pays out (not never, but rarely).

I don't think the two situations are comparable at all. In the ATV case, it was the police who escalated, inappropriately, in pursuit of someone who was mainly a danger to himself. In the destroyed home case, it was the suspect who escalated (repeatedly), from shoplifting to entering a home to shooting at people.
I think following supply and demand curves - whether that be Uber's surge pricing, gasoline during a power outage, lifesaving medicine outside of a crisis, or rent in SF - isn't evil.

Evil would be denying those goods to someone based on their race/gender/age. Or taking action to prevent more of the good from being made/delivered - which you might notice anti-price-gouging laws do.

I played with Weave Ignite the other day which is a Docker-like CLI for Firecracker. Sure there were some rough edges but the overall experience was pretty good. If you are familiar with the Docker CLI you will be able to get some virtual machines up and running very quickly.

Two questions in case someone from Weave tunes into the discussion:

I got the impression that VMs needed an SSH server to be accessible. Is this correct and if so will it be possible to implement something similar to docker exec so that I won't need an SSH server on every VM?

> At the moment ignite and ignited need root privileges on the host to operate due to certain operations (e.g. mount). This will change in the future.

Is there a timetable and could you perhaps elaborate a bit as to why it currently requires root? (I don't know anything about virtual machine internals so this isn't a passive-aggressive question from my side. It's genuine curiosity.)
