Claiming and implying are two different things. It was heavily implied that if you got the vaccine, then you would be able to return to doing things the way you could pre-Covid.

I recently found a fun linear-time systolic sorting algorithm. I'd describe the serial implementation as unconventionally obvious. It's like insertion sort, without all the bother of swapping.

def index_sort(a):
n = len(a)
output = [None] * n
for i in range(n): #can run in parallel, damn the GIL
index = 0
for j in range(n):
if a[j] < a[i]:
index += 1
elif a[j] == a[i] and j < i:
index += 1
output[index] = a[i]
return output
Just a note: right-wing conservatives don't see "whataboutism" to be a fallacy.
Well, thank you for letting me know!
If I buy a flight on Expedia (I wouldn't but that's beside the point), do I get on a plane that says "Expedia" on the side of it? I've never heard of FlixBus, but it seems like the answer would be yes in their case, which is a very relevant difference IMO.
The original Neural ODEs paper is quite readable, and by now there are loads of blog posts and even a few talks on the subject.

The basic idea is inspired by the “adjoint method” for ODE solving (so you don’t have to hold in memory all the intermediate layer outputs — which is otherwise necessary to compute the backpropagated gradient signal).
Woops, I missed that! Thanks for pointing it out. I notice that his site is part of the 512kb club. I'm surprised such a nice site is so slim!

To be honest, 42 isn't actually that bad. PageSpeed Insights scores are incredibly strict (that's a good thing) and not at all linear with visitor perception of loading speed.

news.ycombinator.com has a 100 score, but if you compare the actual "Lab Data" it's not a massive difference.

First Contentful Paint: news.ycombinator.com: 1.3s, potion.so: 2.7s

The biggest difference is Time to Interactive: news.ycombinator.com: 1.4s, potion.so: 11.2s

That 11.2s is pretty bad, but PageSpeed Insights doesn't take into consideration which interactions work before all the JavaScript has loaded. In the case of potion.so, the HTML is rendered on the server (or perhaps statically generated), and the vast majority of important interactions on the homepage are simple HTML links that work even with JavaScript disabled. The 2 big exceptions (and probably the biggest contributors to that terrible Time to Interactive metric) are the third-party embedded video and chat widget.
More war stories: found Timescale easier to setup (maybe just because more familiar), but raw query perf is not something you just magically get for free. Timescale requires a lot of investment in planning. In one project we had simple time range scan queries against a less-than-RAM-sized table taking tens of seconds to complete.

ClickHouse has a bit more ops overhead, but requires very little in the way of pre-planning. Just throw whatever you want at it and it seems to sing by default.

Regarding ops overhead, ClickHouse also has a "local" mode where you can query a huge range of compressed formats without ever performing any kind of ETL step. That means queries can run e.g. directly against S3 storage. For batch logs analysis, IMHO local is a gamechanger. Most bulk logging systems produce massive amounts of S3 objects, and ClickHouse lets you tear through these infrequently (but at high speed) when desired without any bulky/opsey ETL step, and no cluster running idle just waiting for a handful of daily jobs to arrive.

(I love this style of system in general, but the clear engineering work behind ClickHouse completely won me over, I'd apply it anywhere I could)
There's a lot of comments along the lines of "How could the governor be this dumb?" or "Does he seriously expect this to succeed in court?" I recall an interview with Kevin Mitnick where he talked about a prosecutor arguing in court that he could start a nuclear war with a payphone (or something like that???). Kevin just sat there, listening to the prosecutor, thinking to himself that no judge could be so stupid as to believe that. Wrong. Kevin ended up sitting in jail for years based largely on the belief that he could whistle into a phone a launch nukes.

The point is, yes, the courts are, or can be, that stupid, especially when it comes to "hacking". Just ask Kevin Mitnick.
There’s a lot of value in this, and I try to do it at work. I’m confident enough in my abilities that I don’t mind asking questions when there’s something I don’t understand. And I find that people who won’t do that are insecure, and often for good reason.

But still… it can be taken too far. Just as a matter of being a person who can socialize normally, what’s wrong with spending a few seconds explaining yourself? “This is gonna sound silly, but I want the computer in the smallest box. Here’s why.” That kind of thing.

I don’t let my ego get in the way of learning new things. But I don’t go out of my way to sound like an eccentric weirdo either.
To me, this is still very creative, just at a different layer of abstraction.

> In CPU choices, when Apple have lead (PowerPC) nobody followed.

PowerPC was developed by IBM. Apple got involved when Motorola could not deliver a faster 68k to beat Intel's 486 which was passing 50MHz. So they joined IBM along with Motorola and formed the AIM alliance (Apple, IBM, Motorola) to build better processors.

> The M1 is the first time since PowerPC they took a risk.

There's little to no risc (buh-dum-tish) in moving to Arm these days. It's a well supported and understood architecture and found everywhere.

> I really want a linux powered ARM workstation but Apple aren't going to make that.

Apple has the power to steer its own ecosystem. When AMD was working on its Arm A series server processors I kept thinking "This sounds like a backwards approach destined to fail. Why not start by making a performant Arm SoC with 2-4 cores and GPU with a TDP of 10-20W? Target it at consoles/tv/laptops/desktop computing and jump start the desktop Arm market which will naturally lead to demand for Arm servers." The Idea was an Arm SoC that could fill the gap between low power/performance Arm SoC's for mobile/embedded and the power hungry yet performant x86 chips. Basically an AMD version of the M1. That could have really changed things but the big issue AMD would face is where's the Arm Desktop software ecosystem? That's why Apple can take these "risks", they have full control over the whole stack.
Looks like the key contribution is the idea of being able to revoke access to data.

The problem is that democrats are also fostering anti-science anti-intellectualism.

Which side is worse is a matter of opinion. Personally I think they are both dangerous and won’t identify myself with either party as a result.

The result is that there is no point in leveling this accusation as part of a debate about something substantive, unless you just want to derail the conversation into a meaningless partisan bashing match.

Noah's a fun person to follow for those of you who are interested in indie businesses and are on Twitter[0] He's been sharing his MRR growth and learnings while building Potion for awhile now.

@noahbragg - Given that you're built 100% on top of Notion (or at least I think you are), how are you thinking about platform risk long term? They could cut you off their APIs, end life for some undocumented API you rely on, or just build your features into their own product at any point.

I mean, better and worse doesn't really exist. They just are. Being smart has certain consequences, and being inventive has others. And what's better for the world (for some definition of 'good') may not be what's better for the individual - just ask people who volunteer to pick up litter. Certainly it seems like being inventive is much more profitable for the individual than being smart, but of course that's not all that matters.
Good point. Depends on your goals. If you wanted to be generally employable, no; no matter your actual ideology associating with the wrong tribe can be lethal now.

If you're comfortable phrasing it as "maintained high load servers in extremely adversarial circumstances" it might be worth it... If you can find an employer who can value that without judging why you might choose to do it.

> Diet science is chaos.

100%

> What we all need is not another fad diet or fasting strategy or super food, but rather a process that looks like a flowchart so an individual can achieve certain goals.

I really don't think that's going to help. What you are treating as an engineering problem is mostly a human problem. Unless a human is psychologically programmed in a way that isn't counterproductive, few if any processes are going to allow them to improve their health or lose weight on their own.

A lot of times when people "fast", firstly they often aren't actually fasting, but secondly they are often doing so because they see it as a shortcut to gorge their brains out on whatever food they want when the time comes for them to refeed. They may lose some weight, but at a certain point they reach a new set point where they aren't going to see further improvement with the same input, and they're dumbfounded because they didn't take any time to question their original assumptions about losing weight. Giving these people a flow chart probably won't do any good. For a select few, maybe it will.

I've talked to enough people trying to lose weight, and are mystified by hitting plateaus, that I don't think they're going to have the discipline to follow a chart. People get fat not just because of the food but for a variety of psychological issues, and it just so happens those underlying issues manifest in quenching sadness, depression, and anger with addictive junk food. If someone is stuck in victimhood mentality, when they get stuck they'll make excuses to not actually do the hard work of researching, taking measurements, writing down notes, and making adjustments. Instead they'll whine, find excuses to continue eating junk in some capacity, and eventually move on to the next "host" diet fad their pathology can prey upon. It's not uncommon for people to cheat on their diet plan and to not mention it when they inquire with others, only for it to be revealed once too much time has passed. Humans have this strange penchant of being able to lie to themselves as well as others. Try coaching someone who is morbidly obese and there's a good chance you will eventually find out they were having a "cheat day" every other day with a large milkshake.

Those who actually can make a long lasting change need both a reality check and to be honest with themselves. In my opinion, it really doesn't matter that much what particular approach to take with weight loss as long as it involves keeping insulin levels relatively low. Fasting, vegan diet, carnivore, paleo, whatever. Someone who is serious about their weight loss and sheds the victim mentality will be already be able to observe, reflect, and act without a flow chart.

If you are chronically sad, depressed person with low self esteem and learned helplessness, then everything will be a silver-bullet until suddenly it's not, and a cycle of making excuses to break guidelines will just repeat.

The thing about that quote is I used to work on AUVs. And we would routinely say "The AUV swims out to a waypoint" or whatever. So, having established in my mind that a machine can, in some sense, swim, talking about a machine thinking made a whole lot more sense. Things like "The computer thinks I'm a different user than I actually am" or "The computer is thinking of a solution that satisfies the constraints" seemed less needlessly anthropomorphizing.
Then (as it was already well known and evident) you have a deeper problem with a faulty political system, that creates monstrous overgrowths of mental patterns begging for votes instead of progressive ("look-up-to") models.

Telling example: "We believe in self-determination" // "There are unclaimed votes available in those anti-abortionist tribes" // "Ok then, we take them". This should be a joke, not an event. There is a systemic issue.

College is a net detriment to society. The business model of colleges is 'lie to young people and then saddle them with thousands of dollars in crushing debt for questionably valuable degrees'.

The growth in the cost of college hasn't improved standards, but rather it served to fatten administration departments at colleges.

Additionally, quality is dropping severely. I've seen it first hand. I can't count on two hands the amount of new grads from "quality" schools with their shiny CS degrees who cannot write code. Not leetcode, just any code. They can't solve business problems at all. It's like they learned to pass tests. That's CS, which still has some value. What about useless degrees like Political Science or Gender Studies? Those are outright scams given the results. The victims are young people.

At this point, voting for Republican candidates means supporting an institution that has given up on Democratic norms and is clearly aiming at an authoritarian takeover of the government of the United States.

Up until about 5 years ago I would agree that being even-handed on political matters is appropriate. But when one political party has gone completely mad with lust for power and has given up on science and rationality, how you vote is no longer just a political matter. The threat the Republican Party poses to the country and the world is existential.

And yes, there are crazies on the left, but no, they are nowhere near the threat posed by the GOP. The difference is several orders of magnitude.
You're gonna have to cite some kind of example of what you believe pseudo-science is if you're saying critical thinking was somehow detrimental to someone intellectually.

That stress/strain curve in the Cell Matter "Graphical Abstract" is garbage past the point of peak stress. If it's tested in their double shear jig as shown, once it displaces significantly (> radius of the nail) the force is more the pull-out force, basically just the friction between the hole and the nail surface. Or, the nail might just be digging an oblong hole in the shear jig. It's maybe interesting, but a regular stress/strain setup is better to lead with.

The Nature article has some normal stress/strain curves which show brittle failure https://www.nature.com/articles/nature25476/figures/6

To your first point, I think the cryptocurrenc[y|ies] that get issuance and control from a central authority right will in the end come out the most successful, as control of issuance lends itself to enabling modern economic levers any state may want to pull--for various reasons.

Of course there's an argument to be made that cryptocurrencies as we now know them will only ever have intended use as a secondary currency. In which case, fair enough.

AFAIK it does solve a problem with steel, tho: Energy expenditure of production. You cannot make steel with heat generated electrically. At least not directly. Energy dense fossil hydrocarbons are powering furnaces today. You may replace that with generated hydrogen, but I am not sure the math checks out on a global scale.
I don't agree that you look like you don't know a damn thing. You know quite a lot.

In fact, I would happily hire any programmer for, say, a python or a C++ job, that knows nothing about the language in use but knows to ask precisely these questions. Bonus points for questions about function semantics and memory management.

Everything else boils down to syntax and ecosystem/tooling. The former is essentially irrelevant and the latter changes so often and is used differently in different contexts that there is little point in asking about prior experience.

And now we’ve come full circle. Using “whataboutism” to avoid conversations about topics is a problem. Whether you’re using it to deflect to a different topic or using it as an excuse to avoid talking about a topic altogether. Someone could argue your comment is the latter and is just as harmful.

But I think most of that is a limitation of text/internet communication that people don’t consciously notice. It’s much easier to have nuance in an in-person conversation.

Blog posts are probably more readable than Twitter threads; I won't argue that. But if using Twitter is the thing that gets you to get ideas out of your head and into the written word, it's a hell of a lot better than just thinking about that awesome blog post and then never writing it—and, as siblings have noted, the "dump into Twitter, revise into a blog post" flow is both common and totally reasonable.
I'm not actually sure what you're referring to (as CTO I promise you I am not managing any of our GitHub repositories or anything at that level). If you think there are concerns with the PHP SDKs you seem to know where to express those, but a lot of our SDKs start (or are) maintained by contractors as well as contributors from the open source community.

That said, none of this has anything to do with these donations to the open source community. We fund a lot of other initiatives outside of this one thing, and it seems you have some gripes with how we do that, which you're welcome to, but it doesn't take away from this investment.
