I use Anki a few times a week. When I've used it for math (as I work my way through Gilbert Strang's book "Linear Algebra and its applications"), I add full problems that seemed to be key to the topic, or surprised me in some way. These take longer to review, but I find it's been really helpful. And once it sticks, I don't have to review it again for months.

I also find it can be helpful to have a single card that prompts review of related definitions, for instance:

"What are the four subspaces of a matrix A? What are their dimensions with respect to the rank r of A? What are they subspaces of? (Fundamental theorem of Linear Algebra part 1)"

Remembering these things together is easier for me than breaking this down into multiple cards as one piece of this in isolation doesn't make as much sense as a part of the whole.

This is all to say that I disagree with the author on the point that it's important to find ways to break up cards to be bite sized. Otherwise great post IMO!

Some feedback on pricing:

The 1GB free is nothing to write home about, and it's basically just a "free trial" kind of thing, at best. If they really wanted to hook users in, they should consider offering at least 5GB free.

The jump from 1 GB free to 100GB for $30 a year is too large. I think they are missing a lot of people in-between. I have quite a lot of photos, but I don't think I'll need 100GB anytime soon. $30 a year for something like this when I could just use Google Photos for my purposes for free is still too much.

So I suggest at least 1-2 other plans in between, such as 10GB for $5 a year and 20GB a year for $8 a year.

Or if you do offer the 5GB for free, maybe just 15-20GB for $10 a year. I think you'd get a lot more "paying customers" this way, even if they aren't super profitable (they might just be, as the ones that need a ton of space are actually the ones that utilizes everything to the max, while normal people tend to overestimate how much they need).

But once you get this larger audience hooked, it's easier to get them to upgrade when they need more.

It does have legal precedent. There's some spat with a color that's copyrighted (related to vantablack iirc) and the copyright specifically says that the other person is the only person who does not have the right to use the color.

I don't know if that was tested, but I'm not aware of any laws that would prohibit you from excluding an entity or entities from your copyright.

I watched the 4 example videos. While impressive, the first one has so much flickering that I had to stop watching it. The second example is perfect, and you feel very well the connection to music. The third one got me lost; I am a big fan of ambient and cosmic music, but the result did not seem connected. The fourth one is much better, and you perceive the waves of the musical input very nicely.

While using a very different technological approach, the three videos from the right side have a lot in common with the results of Shadertoy.

Many music videos on YouTube are just a static picture; there is an excellent market for your idea. Maybe try to have more examples based on what you see prevalent on YouTube.
Except IP laws don't go this way. I feel like shouting into the wind in these threads.

The bits don't matter. How you got them does. If you'd pull the exact same sequence of bits from /dev/urandom on your first try, you'd be fine. But you didn't, you used a program to download the video from YouTube. You didn't download it through publisher-blessed means. In fact, the publisher and their proxies expended effort in shutting down the expected, "normie" ways of downloading it. In this way, you circumvented the technical copy protection mechanism (no matter how ridiculously trivial it was).

If you write an extension that automatically saves the streams your browser renders for you, that'd be "circumventing technical means" too, at least in case of YouTube.

That's the thing with intellectual property: it tags bits with colour, out of band, and you can't get rid of it without engaging with IP laws.

(Note that I do use your argumentation to defend ad blocking. But that's a different situation. IP laws don't recognize "free to view if and only if you view attached ads" as a colour, but it does recognize the "copyright" colour.)
I used to expect new hires to take a month or two before shipping real work. I think it’s still good as a courtesy - starting a new job can take some adjustment - but new hires regularly start shipping real work in a couple weeks.

Orion is home to a whole bunch of stuff that the human eye cannot see that you see in this photo, especially Barnard's Loop and the Lambda Orionis Ring, which together occupy pretty much the entire size of the constellation. They are huge objects in the night sky, yet at H-alpha wavelength they appear too dim to the naked eye to see.

I've been doing a lot of landscape astrophotography lately in which I show these objects rising and setting over familiar landscapes to give people an idea of what our human vision is "missing out" on. Here's one of Orion that I took with a 28mm lens -- i.e. pretty wide angle:

Is it really the case they "have already learned to scale down from threads"? I'm obviously not well-versed in browser internals, but here's the very first sentence of "Threading and Tasks in Chrome":

> Chrome has a multi-process architecture and each process is heavily multi-threaded.

https://chromium.googlesource.com/chromium/src/+/master/docs...

Either way, I think browsers have a very specific scenario, where there isn't much interaction between the tabs, and they need to be well-isolated from each other. I don't think that's a good reason for everyone else to move away from threads.

Don’t Fall for the Self-Charging Hybrid Con
tangentially related, but have you ever had to deal with statistics on a table indexed on (x, date), where there are a few million rows added each day, and x could be [0,1000], with a distribution like 80% of rows owing to only a few values of x.

ran into a situation like this where after enough days of data had accumulated, postgres would eventually fall behind on updating stats, such that a week could lapse without stats being updated, causing the query planner to think no rows existed within that time range. This would result in a nested loop instead of a more efficient hash join, causing a query to take 2 hours instead of 2 seconds.

increasing the number of rows sampled with set statistics didn't seem to help. wound up running a cronjob to inspect pg_stats, and manually running analyze when enough days had lapsed without most_common_vals being updated.
> Why wasn't this mentioned in the Bible?

The universe is quite large and the bible is a fairly small book. It is difficult to see how it could cover everything. If the prophets were adding interesting technical details on how the universe fits together hopefully some P = NP tips or guides to fission or somesuch would be further up on the priority list than the state of salvation of alien souls.

I'm not religious at all, but I don't see why the Catholic worldview would have problems with the idea that aliens exist and God has made some sort of arrangement for them. Maybe god just compartmentalises civilisations really well, god has many talents.
Just wondering if anyone has tried combining Anki with handwriting for improved retention? (any personal experiments?)

In language learning, memorizing words in a shallow way tends to not be as helpful as memorizing them in a sentence (shallow vs deep encoding). One can try to ankify sentences, but it's too easy to click on the green button and fool oneself that one has mastered the sentence. Anki works great for snippets of atomic knowledge but doesn't work as well for sequential/series knowledge like sentences.

On the other hand, there's another method called the Gold List method which is a pen-and-paper based SRS system which requires writing out complete sentences and testing recall every 2 weeks or so. Pen-and-paper folks like it, but due to the limitations of paper, implementing a proper SRS is far too tedious.

What if one were to use Anki for the SRS part, and handwrite the responses? Handwriting sounds tedious, but I wonder if it helps deepen the encoding? (by forcing reconstruction of the sentence, slowing one down enough to dwell on the form and grammar, as well as adding a physical element to the task)
That's a second preimage attack not a collision attack.
Of course you are only processing the photos that survived. Preserved artifacts are not an argument that storage technology was better back then. It is just selection bias.
I did this accidentally a few weeks ago, and it was such a good experience I have done it intentionally a few times since then. I was just walking in my own neighborhood, but it was a similar feeling to what it's like traveling in a new city for the first time.
What programs do people use for Anki? I've tried the usual suspects, and found them a little too tedious. What I'd love is:
- seamless syncing of cards between my devices.
- more thought into the engagement loop (ie getting me to not be lazy and actually do the work).
- an easily searchable database with credible curated decks.
Looks nice. I spent ages trying to find a solution that does a nice mix of cross platform, own hard drive, cloud. I eventually found it in the shape of https://mylio.com/

Along lines of other comments here, none of my other material has even like the same value as my family photos, so I'm stupendously careful with redundancy / multi location backup.

In case anyone cares: local HDD attached to Mac, Synology on local network, folder on there synced to Dropbox and finally Synology C2. Too far I know, but it's worth it.

Mylio is fast, clever (has a nice P2P model for in-network syncing), doesn't have to hit any cloud service if you don't want it to, good search, great management tools. I rate it highly.
> Well I'll take the bait, is there like a second god for other planets and species?

No, the God of Catholicism is the God of all Creation. That means the entire universe, including time itself.

> Would non-human intelligent life have souls?

Catholic teaching is that all life has some manner of soul. Humans have rational souls. Intelligent life would therefore have souls.

> Why wasn't this mentioned in the Bible? Doesn't this mean that both creation stories are inconvertibly false?

Why would it? It doesn't claim to be comprehensive or complete.

> how could they square away the fact the vast majority of all life could exist without knowing salvation via Christ? Being ignorant of Christ doesn't automatically mean you are damned, but this now means belief in Christ is optional and kind of just a localized thing some humans choose to do

Many, many human begins lived and died without knowing Christ. Why would aliens present a problem? Perhaps they wouldn't even need it. CS Lewis wrote science fictions with un-Fallen aliens. Maybe such a thing could exist.

> if for example aliens claimed their savior was the "real" messiah, how could you dismiss that?

Catholics don't seem to have a problem dismissing other messiahs. Why would an alien messiah be different?

> events the Rapture essentially cease to make sense or will have to be radically re-imagined.

The Rapture as depicted in something like Left Behind is not how the event is generally understood in Catholicism or other sects. There's no reason it would have to change at all.
Actually, deb is way how to "distribute" software not to "just" install something. Let's say I would like to install Docker I will need to type following commands in case of Ubuntu:

(
sudo apt-get update
sudo apt-get -y install \
apt-transport-https \
ca-certificates \
curl \
gnupg-agent \
software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88
sudo add-apt-repository -y \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
sudo apt-get update
sudo apt-get install -y docker-ce docker-ce-cli containerd.io
)

How would `.deb` help you to install/uninstall such software? Do mind mean embedding some scripts to add third-party repository and then install your app?

Even then, what it actually changes from the script I have already suggested in previous post? It is still about downloading two files (signature and packaged application) and install it (e.g. via dpkg --install).
POSIX interoperability isn't to be taken lightly. WSL is currently still pretty far imo from the native experience you get in Linux and Mac. Mac is also the only system that allows easy development of any platform, though of course that's primarily because of locking down development for their stuff.

Macs are popular dev machines because they couple the above with a very polished and stable widely compatible OS. The broad market appeal with the advantages of Unix like terminal and file system and a package manager. The screen isn't even that great, I'd take the XPS screen over the Macbook's.

> The old school "cpan" command has not been recommended to be used for nearly a decade now. Maybe that is your issue?

I did not know that it was not supposed to be used, so that might explain my issues, but at the same time it did work for me on my machine, but had a hard time running my Perl script on a VPS, because I had to set everything up again and for some reason I ran into some errors.

I often ran into packages that failed to compile, too, yeah.

> Never worry about pinning since nothing is ever updated on cpan anymore...

Nothing makes it kind of sad. :/
I was exposed to some basic personal financial planning when during high school. However, it was (and still is) part of the curriculum of the JROTC program (among other things like managing stress, first aid, map reading etc). The focus was more along the lines of setting up a budget and not spending more money than one had/earned.

I am not so sure that teaching kids in high school about the various types of interest-bearing accounts or the different markets for financial instruments would be as valuable as simply teaching the basics of how interest works. That way those students who continue on to college can make a more informed decision should they need student loans to help pay tuition.
Interesting. I was fully expecting this license to also prohibit any uses involving proof-of-work-based cryptocurrencies, but it only focuses on fossil fuels.
I think you need to go actually spend some time with powershell before you make more assumptions about it and it's behavior.

> Shell has a kind of code <-> data <-> code <-> data architecture, i.e. programs in different languages processing standard language-independent data formats (lines of text, JSON, HTML, QSN, etc.)

Powershell natively understands these with builtins. You can convert from and to json, xml, html, csv, and excel.

> What if I want to pass some data to R and plot it?

Just pipe it to your R program like you would any other shell.
Under GDPR I believe they only have to give you "Personally Identifiable Information" (PII), aka "any piece of information that relates to an identifiable person".

It seems likely that some YouTube content does not fall under that category.
I think that is possibly why this post is valuable. That is, the OP isn't some kind of remarkable genius. He's just an average person who was in the right place at the right time. I think it perhaps also goes to suggest that some big players might barely understand how they themselves made their money. This is why someone was eager to buy a simple algorithm; they barely know what they are doing. Or why they wanted to hire him as a quant. How bad are their quants that someone with 5 minutes of experience is beating them?

After entering the industry, my biggest takeaway has been how incredibly many people do not actually possess the competencies you might have assumed. Every level of the hierarchy is full of idiots whose presence there is mostly due to luck or connections.

> Modern OSes don’t allow userspace code to directly access peripheral devices, GPUs included

This depends a lot on the OS and on the peripheral, but this is certainly not true across the board.

RDMA verbs, for example, definitely involve userspace directly communicating with the NIC, with no kernel involvement.

At least some of the AMD GPU graphics stacks support userspace submission to the GPU also, see http://www.hsafoundation.com/html/Content/Runtime/Topics/02_....

This requires hardware support, like an MMU and ensuring bad submissions from userspace can't do bad things to other processes, but lots of hardware supports these things.

The windows graphics stack does require going into the kernel to submit work to the GPU, but that isn't the case for all operating systems and all peripherals.

somewhat related: GPUs started getting support for virtual memory in ~2006 or so [1] but the windows graphics stack was improved to actually use that capability in Windows 10, ~10 years later [2].

[2] https://en.wikipedia.org/wiki/Windows_Display_Driver_Model#W...
Ok, that's a fair point. So maybe some serverless tech can be more specialised and thus better than the Linux kernel at managing, effectively, virtual memory.

If everything is written in-house I still think any API would be simpler but I guess this way some functions can be supplied by vendors/open-source which currently cannot be composed into an e.g. flask API. So it would be nice to have a way of composing APIs from simple functions supplied in packages for this use. I guess that is what serverless is.

You might also have noticed that they almost always mention percentages ("less than 3% of users") instead of real numbers ("one million users") to make these incidents seem MUCH less significant.

“Hiring Is Broken” Discussions Are More Broken Than Hiring
This whole idea that being without a phone is somehow liberating — and just not using it is definitely not as pure and wholly amazing as being completely without it — is to me a silly and predictable response to the very real drawbacks of high tech modern life.

Phones have value. That’s why people use them. Pretending they don’t and that we’re all brainwashed doesn’t change that reality.

Here’s an example: I want to take public transport to a grocery store. I walk out the door. I don’t have my phone.

First of all, if I don’t check the opening hours of the store before leaving, I now have no idea. The whole trip may be for nothing.

Secondly, when planning my trip, my phone would help me suggest what line and where to switch, if necessary. It would alert me in real time of any issues, again with alternate suggestions. When traveling: no music. No audio books. Just the organic, wonderful and inspiring sounds of the city. Not to mention all the wonderful people on public transport you’re aching to know better.

When I get to the store, I may have forgotten my shopping list. And even if I brought it, I have no way of getting in contact with someone that may want to add something to it. If I find a new product I don’t recognize and I’m unsure of whether it’s overpriced, I can’t compare to any other vendor. I also can’t check reviews from other people.

I’m sorry if I sound cynical, but sometimes I feel like the spread (but not necessarily the preaching) of this whole luddite idea of smartphones ruining us is mainly fueled by people young enough to have grown up with them being everywhere, because I’m in my mid 30s and I remember what life was like without smartphones, and for the most part, it sucked.
