Unfortunately it can be upvoted by people who mean well and want to bring awareness to climate issues. This is a setback for those of us who really want to understand what's going on with droughts this year. For example, is the Colorado River drying up? Not really, Lake Meade is at historic lows up upriver bodies like Lake Powell are not. It's difficult for me to wrap my head around many of these climate issues, but I'm happy you went kayaking.
I was fortunate to have problem solving based DiffEQ classes as a freshman, and my prior experience in programming meshed well with differential equations.

My first published Android app was a differential equation visualizer:

It definitely can be used like that successfully. Generally there's long term impacts of internalized shame like that though, which can bring about lots of anxiety and depression.

I've been trying to find positive reframes for things like that -- "I want to quit smoking because I care about my health and want to take care of my body" vs "I want to quit smoking because otherwise I'm just a fuckup that's going to die of cancer"

(at the very least in this case, "I want to quit smoking because I'm tired of hacking up a lung every morning feeling like I'm going to die", which is more a biological imperative than anything)

Glad you're physically healthier for it, and that you're tending to personal relationships. Please be sure to take care of the mind as well :)
As the article says, yes
Around 50 years ago, I was a math major and consequently required to take a course on differential equations. For perhaps the first time, I was taking a class on mathematics that just didn't click for me; nothing was intuitive. The class was just a big bag of complicated tricks. Each category of differential equations covered in the course had its own special trick. There was no general or universal approach to solving a DE; one had to recognize a particular problem was a DE from a particular category and apply the special trick to solve it. The methods were often long or complex and they only solved some differential equations. Many differential equations have no trick at all to solve them. It turned out to be a tough class for me because I'd never before needed to learn math purely by rote.

Those that have taken Integral Calculus may be thinking that solving DEs sounds akin to integration where one may have to apply substitutions, integration by parts, trigonometric substitutions, or partial fractions. Yes Calculus requires learning a bag of trick too, buts its a small bag of simple tricks with wide applicability. So many of the functions one needs to integrate succumb to this small bag of tricks that it's almost fun to hone ones technique. A class on elementary differential equations is just depressing.

To be fair, differential equations are important. Physical phenomena are often best described by differential equations. Fortunately, programs like Mathematica can be used to tackle real world differential equations one way or another (perhaps with numerical methods) to obtain solutions.

I was fortunate to have my Probability course (sadly, not my differential equations course) taught by Gian-Carlo Rota.
Yes, Apple folks that are listening…please do not screw up preview.
First to OP: Why are you denying users the use of your service by beating this dead horse? Does that really in any way serve your users?

The current state of affairs with iOS is the context is which we must make decisions. So many of the posts here strike me as useless complaining about the reality on the ground which cannot be changed.

You want to hack? Simple - get an Android or PinePhone.

You want to share your hacks with friends? Simple - make a PWA.

You want to make an app for the general public and don't want to deal with app store bureaucracy? Simple - make a PWA.

Your app requires native features? Then learn to navigate the app store approval process.

I have several friends and colleagues who have launched public apps. Some went the PWA route. Some went the app store route. All have achieved their mission. It's informative to hear their answers as to their choice. Those that choose the PWA route mostly did so because they already had a web service, and just wanted a good mobile version. Those that went the app store route said in effect that it's not really an app (in the minds of their user audience) if it's not in the app store, and were not already providing some service via the web.

Granted this is a small sampling of half a dozen. I would love to have a wider sample to review as I am interested in transitioning from desktop web to mobile app development, and want to invest myself in a good foundation. Does anyone know of a good (and recent) article where developers of successful apps are interviewed and ask to explain their platform decisions?

A final comment is this. I think Apple is working to make PWAs a viable choice partially to reduce their approval burden and incentivize developers of "simple" apps - like that of the OP - to go the PWA route.
We give them plenty of help. What we don’t do is force them into shelters or mental hospitals, so many voluntarily choose to the live on the street. I remember one particularly cold Chicago winter where I made a couple dozen sandwiches to give to the homeless. I drove up to one of the large encampments under a bridge in my neighborhood where a guy was begging for money from cars passing by. I pulled up and offered him the sandwiches, and the guy smiled and said “no thanks, we just ordered a pizza!”. Mind you, these people were living in tents in the dead of winter!

I remember another time when I bought a few different food items from a convenience store and offered them to a couple homeless guys sleeping in the sidewalk in the middle of downtown. They picked through the five or six items and each grabbed one thing. Nothing wrong with having preferences, but it astonished me that they didn’t want all of it.

These people are not being deprived of their basic needs. They just don’t want to live in shelters.
And in the opposite direction Windows executables can always be loaded as libraries. There's also rundll32 for libraries designed to be run like executables.
We support that. If you want a freedom-optimized build:

make -j16 MODE=tinylinuxbsd

Will produce ELF executables that run on Linux, FreeBSD, NetBSD, and OpenBSD. You'll never have to worry about being red-flagged by Microsoft. You won't have worry about Apple breaking your binaries. You won't have to worry about Glibc's license or wine binfmt_misc issues. Your binaries will be smaller, starting at 8kb in size. It's real nice and still supports 4x more platforms than the existing tools. If you use it, please note that "tiny" modes disable a lot of cool features like --ftrace and --strace. You can turn them back on by putting:

ifeq ($(MODE), linuxbsd)
CONFIG_CPPFLAGS += \
$(BACKTRACES) \
$(FTRACE) \
-DSYSDEBUG \
-DSUPPORT_VECTOR=113 \
-O2
TARGET_ARCH ?= \
-msse3
endif

In either ~/.cosmo.mk or build/config.mk. Then you'd say `make MODE=linuxbsd`. We also ship a `tinylinux` prebuilt amalgamation on https://justine.lol/cosmopolitan/download.html

Lastly, you can always change the .com extension to .exe. I would have chosen the latter, but I think UNIX has more in common with DOS than it does with Windows. I know people in the Microsoft camp hold negative associations with .com. But I didn't want people in other camps to think APE is just a Windows program.

What made me dislike Diablo 3, is that for me it fails to deliver the atmosphere that really made Diablo 1 and 2 a game worth experiencing.

Diablo 3 is too colorful and looks like it has been heavily influenced by games like World of Warcraft (in a bad way).
A powerful engagement and influence was left by MySpace, but it's not put up in protective glass for ticketed visitors to take snapshots of. I appreciate the nuance of its impact on the world, but... we've moved on.
I enjoy the overall fashion in which he presents the topics — clear, motivating example to start with, building on relevant details etc. His textbooks read like a good popsci book, yet they are of course much more detailed.
I’m not sure how suitable his e.g. « Nonlinear dynamics and chaos » are for math students, since it feels a bit informal, but for developing intuition, interest and the scope of the subject, I haven’t seen anything better.

I was listening to the Lex Fridman interview of John Carmack[1] the other day and find myself agreeing with Carmack. Essentially, building the metaverse is insanely difficult but also desirable for a variety of reasons. I'm glad that someone (sucks that it is FB) is investing heavily into the R&D to make it a reality.

As for the new avatar, it's just the first draft so to speak. Given the talent at Reality Labs, I'm certain that things will look much better a few years from now. People often have this vision of what VR/AR should look like and will be disappointed that v1.0 does not live up to those expectations. As long as incremental progress is made, it will compound over time and eventually we'll get there.

They do not. It would be difficult to plan correctly if your free disk space is… variable.

Example:

You have an existing 40 gigabyte file

It happened to compress well

You delete it and your free disk space goes up by 4 gigabytes.

You then write a new 40 gigabyte file that doesn’t compress well

Replacing an existing file of the same size just ate an extra 36 gigabytes.

How would you plan around that? SSDs should store the bytes given and don’t play fancy games.
How can you know without trying? Seriously? Humans are a blip in the evolutionary timeline and you not reproducing is not gonna affect humans in any way. I'm a guy who is 30 as well, and I'm brown, I know I don't have a chance in the dating apps in the west, but I don't want to complain, there's other avenues to dating, if that's what you want.

You are better off not being a relationship which hurts you, more than being in one just for the sake of it.

To blame dating apps, hookup culture, divorce rate etc is extremely easy. And I understand the personal frustration and as someone who has never been in a relationship, never had sex, I don't think I'm missing out on anything, yes, I do yearn those things, but honestly, you really can't force things to happen, and life is not a movie, nothing is guaranteed.
"Flip the script" seems like a fancy way for you to deflect from answering the question.

I can tell you locally we put people in jail when they defecate in the streets or shoot up in public. We also offer space at shelters for people that can follow basic rules - no drugs, no fighting, etc. In addition, our local food bank is fairly well stocked and funded, and several churches in the area have outreach programs. The end result is that I can walk downtown and never have to dodge human feces and rarely see a panhandler.
replication is built in to mnesia and your "app" crashing really shouldn't be taking down the entire OTP on your local machine, so ETS would persist on a single node

> Mac hardware feels great, but I just cannot understand why it's the preferred developer platform.

Depends what the word developer means....

In the context of Apple ecosystem developer is quite good, in the context of Windows or game console developer not great, for embedded developer depends on the luck of hardware vendor support for macOS, in the context of certified UNIX developer, it gets the job done.

Not all machines reorder instructions, and not all machines have more than one core. You always need control over your compiler, but that often does not suffice.

With more than one core, you cannot do without one of atomics or custom assembly code sequences. And if the CPU reorders instructions all by itself, you need special instructions besides.

Atomics in the language mean you get to let the compiler worry about most things. But an atomic operation may take enormously longer than you hope. An atomic increment may take a hundred times as long as an ordinary increment.
Are they allowed to cook meth in the place they are given? What about renting it out so they can get some money to buy drugs? Do they have to ever clean it to avoid bug and rat infestations? What happens when their dealer comes to collect? And will neighbors tolerate a dramatic uptick in porch piracy and prowling needed to get money to buy those drugs?

There are just so many ways no strings attached housing can and does go wrong when substance abuse is ignored. Around here, they sure to couple it with at least an equal amount of social services since many of these people can’t live on their own. Costs are around $10k/month.

The nice thing about no drug shelters is that it really works for those that aren’t on drugs anyways. We can’t just assume all homeless are on drugs and can stand being in permissive shelter/housing environments (which can be quite dangerous for the above reasons and more).
> It would lower their taxes.

So the incentive to holding unimproved land from which you derive no profit would be so that you would pay less tax then if you would made improvements and profit from those improvements.

You should follow your own advice.
> This is really fundamentally wrong. X drawing commands are still just fine for representing modern within-app UIs and toolkits.

This is really fundamentally wrong. Nobody has been updating X commands for modern effects (eg, blurs, advanced blend modes, etc..). Heck you can't even do round-rect clipping. You have to generate a clip mask pixmap instead. At which point I might as well just generate the final pixmap and forget about X anything. Especially since xlib doesn't even do anti aliasing. Like come the fuck on, it's friggin useless. Can't even handle text adequately!

There's a reason Wayland dumped it all entirely. If it had been maintained and updated sure maybe. But it wasn't. It's a drawing library straight out of the 90s, absolute abandonware

> Sucralose was an instant no to me when I saw the molecule. “Here let’s hang a chlorine off this here sugar.” Nope. I recall seeing similar sentiments in a thread over at Reddit where a biochemist remarked that it looked like a pesticide.

If you could infer the properties of a compound by making vague analogies to other similar looking molecules, chemistry would be easy. Changing a single atom can completely change the safety properties of a compound, ie. H2O->H2O2, Hg2Cl2->HgCl2.

> The weird complicated molecules in Stevia and Monk Fruit seem safe precisely because they look like something the body is going to hack apart right away and look like all the other complicated molecules found in plants that the body is used to dealing with.

Yeah, like the atropa belladonna, the deadly nightshade? I'm sure that's chock full of "baroque carbon sculptures". Maybe biochemistry just isn't so easy.
Yes, backpropagation isn't the chain rule itself, but just an efficient way to calculate the chain rule. (In this respect there are some connections to dynamic programming, where you find the most efficient order of recursive computations to arrive at the solution).

Codes of chivalry and "gentlemanly behavior" came about in the context of strictly class-oriented patriarchy. Those codes existed not to protect women but to reinforce male status within that hierarchy, with women being the currency of social transaction. And like the Bushido of the Samurai, most of the culture around it was a romanticized retcon of a brutal reality.

There's no historical evidence of a knight ever having rescued a damsel in distress, for instance. It was far more likely for a knight to kidnap women, rape them to "consummate marriage" and take legal possession of their property. And that was just a privilege afforded to noble women who had anything worth stealing.
This is true generally for all systems; that is, if there’s significant gap between what is allowed by the system, its non-systematically enforced usage guidelines, and how users want to use it, users will find a way to get what they want, especially if doing so does not impact them.

For example, shared a blog post I found few days ago on injecting custom Python syntax/functions into local code; obviously problematic, but something Python doesn’t even attempt to prevent, in part because it is open source:

I phrase it as “The class I cheated my way to an A but didn’t commit any academic dishonesty violation.”

> The real fact that is somewhat hidden is that most differential equations can't be solved analytically. You solve analytically only the few cases that are solvable analytically

I discovered this very early in my semester of Differential Equations. We were allowed a single 8.5x11 notesheet for the exams. As there were only a handful of the “most general” cases which are solvable on paper with a basic calculator, I simply copied the step by step solution for each of the very most general case completely worked out in whatever techniques we were going to be tested on for that exam.

The professor was an engineer before becoming a math professor so he only liked to include real-world situation ODE’s on exams which further reduced the potential problem space.

While it greatly confused the professor/grader who scored my exam that I kept adding zero-coefficient terms before solving the differential equation perfectly…I got 100% on all the exams.

The catch was that I didn’t learn anything. The next semester it turned out that I needed to know those techniques for Reaction Kinetics and Heat&Mass Transfer and Biochemical Engineering (these courses involved deriving and solving many equations from first principles).

I had to crawl back to my Differential Equations professors office hours for 3 weeks and beg him to actually teach me differential equations. He was very confused after asking me what grade I got (an A) and I had to explain to him how I got an A without learning anything.

To his credit, he did a fantastic job assigning me custom work for 3 weeks and reviewing it with me and I was able to learn what I needed for the more advanced courses.

But without his help and some additional tutelage from my peers, I would have been completely screwed for the rest of my Chemical Engineering major.

I can't speak to Voice of Fire, as I've never seen it in person, but the reaction seems rooted in whether people value color equally to shape. I.e. "The shapes in the piece are simple, therefore the piece is simple."

Edit insert: I dated an artist for a while who did a lot of color theory work, and IMHO the choosing of precise colors (especially over large areas) is underappreciated as a stimulus for ultimate experience.

It's difficult to say from white balance on photos, but from memory Guernica isn't simply white, gray, and black. It's an ugly, uncomfortably hued, just barely noticable off-pure color palette.

https://www.artnews.com/wp-content/uploads/2020/05/8562495a....

Voice of Fire is likely a much more extreme example, but my experience with Guernica was not that it was more... but that it was fundamentally different than reproduction in miniature.
They’re technically military, but they’re under the command of the civilian city prefect, and there’s no crossover with other military units, so I’d say it’s more a relic of the past than an actual real difference in way of working or organising
The fundamental difference is between the sugar ring (flexible, which each carbon having tetrahedral geometry, and localized electron density) and the aromatic benzene ring (flat trigonal geometry, with electrons delocalized over the ring).

If you attach chlorine to the latter, you end up with something that's very hard to break down (very persistent) and which will often (depending on exact structure) stick tightly to many biological molecules. Thus they can cause developmental disruption, odd forms of cancer, liver damage, etc. For example, TCDD (dioxin, a side product of many herbicide synthesis routes, a notorious component of Agent Orange formulations in Vietnam, etc.):

https://en.wikipedia.org/wiki/2,3,7,8-Tetrachlorodibenzodiox...

The chlorinated sugar ring is probably easier to break down but if this produces an activated chlorine species during metabolism, say in your liver, it might bind to who-knows-what and cause problems. Or it might just get excreted as a chlorine ion, no different from NaCl (table salt). I'd avoid it myself.

Some organo-chlorines (and -bromines) also occur in small amounts in many edible seaweeds, apparently often with the halide attached to fatty acids and lipids. Hence consuming large amounts of seaweed might not be the best idea either.

That is a very cavalier way of looking at it. This is the radiation fallout map from Chernobyl. In all darker red areas you still have to radiation test wild game and people are advised to not each too much mushrooms.
