My general practice with mathematics is and Anki is to:

1) Understand the material I'm learning.
2) Put explanations of any algebraic procedures (for instance, the dot product of two vectors) as a flip card.
3) Put a single example of doing the work in a flip card.

For important proofs, I put them in Anki using Cloze deletion. I just drop in the whole proof, and knock out portions. This has been extremely effective in remembering and understanding the proofs. I also do this for geometric explanations of procedure.

This is definitely not overkill, and creates cards that you can go over really quickly. Ever since I have begun doing so, I have found that it is far easier for me to apply what I have learned, and that I can more easily understand the options that I have for finding solutions to problems, because I have all of the options available without requiring me to look over old information. It's just there.

Ever since taking Barbara Oakley's classes (Learning How to Learn and Mindshift), I have been a more productive and emotionally stable human being, and my ability to learn and understand the information that I am learning has exploded. One of the most important things I remember mentioned in that class was that memorization and understanding are actually quite tightly linked.

There are things that I have dealt with in the real world that would have been solved by math lessons that I've forgotten since I left University twenty years ago. I was never very good at studying because of anxieties and procrastination. The simple fact that I know I'm going to put information into Anki allows me to concentrate and gives me procedure no matter what I'm trying to learn, regardless of source (readings, lectures, etc.). I wish I had this ages ago.
It's not at all crazy to imagine laws that simply limit the total amount of money spent on a campaign, regardless of where it comes from.
> Facebook said it is asking the influencer accounts that posted the Bloomberg memes to retroactively use the tool meant for such posts. After this happens, the posts will be labeled as a "paid partnership" with Bloomberg.

> Campaigns that avoid using the tool, as Bloomberg had, risk having their accounts suspended.

I don't see how this is a bad thing. Facebook made the right decision here.
It could be the actual wireless link that's oversubscribed, with QOS favoring Netflix.

If it is the wireless link, getting link budget up does really help.
> Every high density over crowded over built city ..and this is global..is unaffordable. It has expensive utilities, higher taxes and bad declining infrastructure that the government can’t seem to replace or upgrade.

That's not true. Houston and Dallas are big cities without affordability problems. Sunnyvale, CA (quite dense, and becoming more so, but suffering from these NIMBY problems) is one of the safest cities in the country. Well below the average crime rate of many rural towns.
It goes to show that housing is a national issue that needs national solutions. We need federal legislation.
Quite the opposite: political speech is one of the most protected forms of speech. Your example for polling stations is a very narrow case where the integrity of the election takes priority. Your second case is effectively just pointing out that trespassing laws exist.

> No one has an unrestricted right to go out and literally speak, as that right to do that is balanced against other rights and considerations. What's so different about the right to spend? Why can't that right be balanced against other rights and considerations, too?

You're right: spending is not treated very much differently than speech. Can a state pass a law that says people are limited to 30 political posts on social media per week? Can the government enforce a rule saying "people are limited to 30 hours of political activity per month"?

Campaign spending - that is, money that is being given directly to candidates - is already limited. Citizens United did not change this. What is unlimited is spending on activism unrelated to any particular campaign. Say you and some of your friends are worried about climate change, and put together some money to run ads or billboards not promoting any politician in particular but encouraging more work on preventing climate change. Can the government swoop in and say, "sorry you've reached your spending limit for climate activism"?

The courts decided no. Putting caps on this sort of activity is an infringement on people's right to free speech.
Ask HN: Should you stay in a loveless relationship for kids?
Asking for a friend with permission.

My friend is in a Loveless relationship, with a 2 year old toddler. Both parents work remote, both make over 6 figure salaries so jobs/income isn’t an issue. 25 and 28. My friend is the younger one.

They’re essentially co-parent roommates with none of of the benefits of being single or in a relationship.

Never married, just relationship and kid together.

My friend wouldn’t be keeping the kid And the other parent will likely take the child and move 3 hours away (flight, albeit cheap and not an inconvenience)

My friend loves his child, is so passionate and excited then around the child. It’s beautiful to see them interact but again, the loveless relationship... and my friend is depressed. Currently on antidepressants.

However they’ve noted that being single would eliminate a lot of non romantic issues such as debt, lack of savings, investing, Finishing school etc. while still providing and seeing said child. But obviously the lack of both parents will have implications on child and parents.

Friend is really lost
For a candidate, I can only donate $2800 towards primary election efforts, and $2800 towards a general election effort. Bloomberg, any candidate, should be prohibited from spending any more than that on their own campaign, billionaire or not.

Technically a mule also has a lower chance of conception.
I wouldn't describe the results you show in the photos as "worked really really well". The traces are uneven and full of holes and discontinuities.

To me that's completely unacceptable. I'd throw them in the garbage but I guess I'm too OCD and obsessed about quality to work with hand-etched PCBs.
That's the point though. Value isn't "money" -- that's not pedantry, it's a comparatively profound truth. Asserting that this business arrangement constitutes getting something "for free" is missing the point.
I've been on IRC daily for over 22 years.

I know exactly what you mean. I've gone from one tight knit community to another. In the between time I've either taken short breaks or been hanging out on freenode.

Right now I'm lucky enough to be in a tight clique of people with a private server.

Some of them have been on IRC for as long as it has existed. Most of us also meet IRL regularly.

If you find like minded people IRL you can start up IRC again.

Edit: Speaking of freenode. Just a few years ago I remember having a lot of fun in the wolf game channels with random strangers. It felt like the 90s again.
How can something immaterial emerge from something material?

By immaterial experience or phenomenon in this case I mean qualia

"Examples of qualia include the perceived sensation of pain of a headache, the taste of wine, as well as the redness of an evening sky" from https://en.wikipedia.org/wiki/Qualia

You can tell me the hue of the sky, the brightness, etc, but that's completely different from your actual perceived experience of the sky, which is what consciousness is

Another quote: "what it is like to taste a specific apple, this particular apple now"
> This is also why I don't rate Uber drivers.

It was here on HN a number of months ago that I learned that in the Uber world, 3 stars does not, in fact, mean "acceptable". That knowledge altered my view of all reviews, including Amazon's, in two ways:

1) Like you, it means that I'm no longer willing to give reviews/ratings. If there is no consensus on what the different numbers of stars mean, then I can't be at all comfortable that my rating will indicate to others what I intended to indicate.

2) It means that I no longer put any weight whatsoever on ratings I see from others, for the exact same reason: I can't know that what I think the rating means is at all what the rater intended it to mean.

That 3 and 4 star ratings hurt Amazon sellers underlines this problem.
> Supreme Court has ruled money is free speech. It will take a constitutional amendment to change this.

It's clearly not that simple, because there are a lot of laws about campaign finance in the United States. The court ruling that money is speech obviously doesn't mean that there are no restrictions on how money can be used in campaigns, and it doesn't mean those restrictions can't be changed with laws.
If you look at the data for SF, 95% of brand new units are first occupied by people who have lived here for a at least a few years. New housing serves people who are already here.

What causes people to migrate to the bay is the office creation, not the housing creation.

I've spent over an hour going 10 miles on the 405 recently, so hopefully they'll use the autonomous infrastructure to deliver work to the remote extensions/areas as well to turn back the clock on congestion a few decades in the existing cities.
>> No one has an unrestricted right to go out and literally speak...

> Yes, you do have every right to go out on public property and literally speak.

No, you don't. Most states have laws that prevent you from doing that at a polling place on election day:

For example:

https://www.nass.org/sites/default/files/surveys/2020-01/sta...

> During the hours the polls are open, a person who is in the polling place or within 200 feet of any entrance to the polling place may not
attempt to persuade a person to vote for or against a candidate, proposition, or question.
The problem with Three is they don't have enough spectrum especially in densely populated areas, they definitely have invested a lot in backhaul capacity. 99% of cellular data problems are nothing to do with backhaul or peering, it's spectrum usage.

Some good news: they are aggressively rolling out SDL (supplementary downlink) which will really improve things. They also announced today their 5G network (which has by far the most spectrum of all UK carriers) has went live. I would expect insanely good speeds on that network.

But yeah, turns out selling unlimited data/tethering/roaming/text/minutes for as low as £11/month isn't a good business strategy.

Generally though: EE is good everywhere. Vodafone is good in North London, O2 better in South London. Three generally awful everywhere.
The IDE was still a 32bit app and was seriously unreliable and insanely slow last I looked (2017 or so, the compiler finally got 64bit support though!).

The state of public transit to/from LaGuardia is terrible, but unfortunately it's hard to imagine any notable subway expansion happening any time soon given Byford's recent resignation (in the face of Cuomo's constant meddling) and the constant back and forth bickering between Cuomo and de Blasio.
Marianne Williamson seems like a lovely person, but she's not even close to being a serious candidate. I can't blame people for not being interested in her campaign.
The thing is that they only make the "right decision" when it benefit one party, those things aren't issues for them when it benefits the other side.
Although if someone visited a suburban area in Japan and complained that it had "mostly old Asian people", they'd probably be called racist.
To me, the circuit did its job, so it worked really well.
How about some of the much denser megacities? For example, Tokyo, or Seoul? Both are far more affordable than the much less dense first tier cities of the US.
I like the K&R book, but I think what really taught me the most about C was actually writing programs in C. And playing around with particularly interesting features like function pointers and OS library interaction such as dynamic memory allocation.
Despite the name the motivation for the geometric product is principally algebraic, ie. it's useful for doing algebraic manipulation. It does not, AFAIK, possess any geometric meaning outside of special cases.

(It's "geometric" in the sense it doesn't depend on a choice of basis I guess.)

Not it shouldn't. We know that these companies are morally corrupt. When you sell your time to help grow these companies you are also morally corrupt. Simples.
Ah, it’s been too long: everywhere it says “Telemundo” above I meant “Telefonica”
The reason we have a housing crises is because people want high density living. Our market crises is a literal refutation of your proposed solution.
Having a couple lines that are similar or copied in several places shouldn't be considered such a bad thing. Repetition reveals similarity, and having clear signals of similarity is really important. It's often more expressive / easier to understand than a single method name.

Premature abstractions are way worse than repetition. A poor or insufficient abstraction leads to obfuscation which leads to misunderstanding which leads to novel constructs for the same responsibility. Because a poor abstraction can be really really difficult to back track, you end up with hacky work-arounds to get something done.

I think encountering novelty in a codebase is the biggest thing that damages comprehension; and repetition actually enhances comprehensibility.
AVIF is open source so it doesn't matter if nobody supports it. Just clone the source of a decoder, and you have the source forever. But, obviously, Google, Netflix, Mozilla, and others have all committed to supporting AV1, and that means AVIF, by extension, will be supported for a long long time.

AV1 is even getting hardware-based decoding support.
> there's a good chance you'll eventually get an email asking you to remove the 1-star review in exchange

Wow. I've never given an Amazon product a 1 star review, but if I did, and I got such an email, I would absolutely update my review to warn everyone that this is happening, and that the real average review for the product is likely to be lower than is shown.
How many good products need hustlers? We're living in the age of easy product/service discovery.
A lot of that stuff is overtaken by events, but I clearly say that the essay was written in 2009. Nevertheless, if you wanted to see what I wrote in 2009, there it is. It hasn't disappeared from The Ether, there's a disturbingly large amount of information that was written only a few years ago and has totally disappeared. One of the reasons that much information has disappeared is because the website can no longer stay running. If your website is designed to last, then the information is more likely to stay available. Yes, I know it's more complicated than that. But it's a start.
Its pretty simple I think. You can collect, store, process, track, do whatever with data as long as that data cannot be used to identify the single individual person that produced that data.

If on the other hand the data you want to collect or track can identify a person, you should ask this person if (s)he is okay with it before you do it.

Seems fair enough to me. And it could be me your website was tracking.. or, you that my website was tracking
Are campaign finance laws really the answer? Seems to me like they are regularly ignored without consequence.
It’s not easy clearly if it means that someone else has to pay the price of it without any benefit.

If you want older people/property owning seniors on fixed incomes to move out, pay them. It’s as simple as that.

The truth is that most cannot pay. The value of the dollar they earn is imaginary. The whole system from Wall Street to wages to taxes is a Ponzi scheme.

Land has value. Water or access to water has value. Inherent value. Everything else is value-added. So you have to pay more for a resource that is fixed or shrinking while population increases.

It’s very simple. Buy it off people. OR. It’s far cheaper to add value upon affordable land and water. To not build on something available and abundant and to not ADD value to it is a poverty of creativity and intelligence. To want to evict older citizens or punitively tax them to displace them to take their land and water is not only lazy but also immoral.

These all have distance limitations meant to allow people to access the facility. Outside of those places on public property, you have every right.

This is like saying laws meant to keep stairways clear are restricting your free speech. You are absolutely allowed to protest near an election center within reasonable limits.

To point out how ridiculous these selections of laws are as a proof that free speech is being abridged, I'll point out that Alabama restricts protests to be at least 30 feet away from the site. If 30 feet means you can't get your message across in a public enough forum, I'm not sure what to say.

Also, a lot of those laws are subject to pending legislation.
And the people who did get in often approach the problem as, "yeah, screw them, I got mine." So we have two groups who have countervailing interests. But of course the property owners have more money--and also time, education, social capital, and so on--so they are the ones who usually win this fight.
Those 3 sites are the same company. Twitter for example did the right thing and simply ban all political ads.
“Residents are left with no choice but to take the subway to Manhattan and back ... or take the bus, where ridership has continued to decline.”

So, there is an existing alternative that doesn’t involve absolutely fucking up traffic, and...? People aren’t using it.

So, this sounds like bullshit.
Hi, I don't have advices but I'm upvoting to give visibility.

I think there should be a more welcoming attitude to both remote working and motherhood/fatherhood at faang-level company.

I'm writing this in hope that other people do the same (as in upvoting) and maybe we can make a little difference.

The actual problem here isn't to refactor or not refactor. The mistake a lot of developers make, including here on HN is in thinking of it mechanistically, that the code is just a bunch of operators and data and we've just gotta push it around the page some without really understanding it. That's how a lot of people interpret DRY, as an end in itself to be accomplished by pushing the symbols around and sweeping them up into something pretty.

The most important thing isn't to apply these heuristics, but to understand the problem space in which your code operates before you lay down your abstractions. That's a difficult thing to do without domain knowledge, and in a lot of enterprises you will never get access to the kind of domain knowledge you need to refactor effectively unless you're the lead or in management.

To the extent that your code is a series of statements about how the system behaves in response to a particular data input it's easy to read and documents itself. And to the extent that your data structures and statements resemble statements that a domain expert might make(move gantry 30 meters to the left, then drop the crane) they become easy to change in response to changing requirements. Domain knowledge tells you what the fixed elements of the problem space are(is it always a gantry? Does the gantry move in any directions other than left? What does it mean to drop the crane and do we do it different ways?). That informs how you structure your code and what the most clear factoring is.

It will not always be the smallest refactoring.
Isn't the common meaning of "good enough" "sufficiently good to meet my requirements, even though I can imagine it being even better"?

But you're right, I'm clearly not talking about the same thing as that blog post. What I'm arguing is that there's this appropriation of language where people use "good enough" to mean exactly "not good enough", and I don't think that's helpful.
Back in 2013 the MTA said this about simply making G trains as long as the platforms would allow, which is how most other trains in the MTA work:

> "Longer trains are not in the cards however. The report notes: "Given that increasing the length of G trains to 600 feet at current ridership levels would be a misallocation of NYC Transit resources and could lead to reduced service frequency and crowded transfers, other means were examined to address concerns associated with short trains."

And yet, it sounds like they want to spend billions on this streetcar project.

Having said that, the routes aren't excessively overlapping. The proposed BQX hugs the water, whereas the G train goes inland quite a ways north of Prospect Park.
I have wondered the same. I use both fdroid and signal, but never really understood why signal isn't on fdroid. Can anyone please comment?

Still not enough. Here is why Tokyo housing prices are stable, despite the city growing, while NYC’s continue to go up: https://reason.com/2019/04/02/nimbys-argue-new-housing-suppl...

> According to the Journal, the Japanese capital of nearly some 13 million people saw the construction of 145,000 new housing units started in 2018—more than New York City, Los Angeles, Houston, and Boston combined. The country as a whole has managed to add close to the same amount of new housing as the U.S., despite having about half the population.

What’s remarkable about that last point is that Japan has been shrinking for a few years now, while the US continues to grow.
You're speaking past each other. In marxist economics literature "commodification" means something is able to be bought and sold, not that it is a commodity in the broader ecconomic sense (an undifferentiated good with broadly elastic demand). "Honor" isn't commodified, "dignity" isn't commodified, "food" is commodified, and "rare collectible art" is commodified.
Amazon should provide an incentive for reporting this sort of thing.

1) Requires a private SSH/GPG key that was associated with your GitHub account at some arbitrary date in the near past. It would be trivial to design a cryptographic scheme to prove ownership of a GitHub account without compromising private keys. So why do it the way they have?

2) Requires that you provide government issued identification (and possibly more) to be able to withdraw or sell the airdropped tokens for USD or bitcoin.

Call me paranoid, but this feels like a honeypot. It feels like an attempt to compile a database of programmers/developers (and their real identities) - with a bit of a bias towards those with knowledge in the areas of cryptography and/or cryptocurrencies.

Even if that is not the intent. Would you trust this company to safely store such information about you?
This looks cool, but there's absolutely nothing on the page about OS and hardware requirements. I can't even tell if it's for Windows, Mac or both.
