Fundamentally I think the question is what kind of streams are you processing?
My concept of stream processing is trying to process gigabits to gigabytes a second, and turn it into something much much smaller so that it's manageable to database and analyze. To my mind for 'stream processing' calling malloc is sometimes too expensive let alone using any of the technologies called out in this tech stack.
I understand back pressure, and circuit breakers, but they have to happen at the OS / process level (for my general work) -- a metric that auto scales a microservice worker after going through prometheus + an HPA or something like that ends up with too many inefficiencies to make things practical. A few threads on a single machine just work, but end up taking ages to engineer a 'cloud native' solution.
Once I'm down to a job a second (and that job takes more than a few seconds to run to hide the framework's overhead) or less things like Airflow start to work, and not just fall flat, but at that point are these expensive frame works worth it? I'm only producing 1-1000 jobs a second.
Stream processing with these frameworks like Faust, Airflow, Kafka Streams etc, all just seem like brittle overkill once you start trying to actually deploy and use them. How do I tune the PostgreSQL database for Airflow? How do I manage my S3 life cycles to minimize cost?
A task queue + an HPA really feels more like the right kind of thing to me at that scale vs really caring too much about back pressure, etc when the data rate is 'low', but I've generally been told by colleagues to reach for more complicated stream processors that perform worse, are (IMO) harder to orchestrate, and (IMO) harder to manage and deploy.
The cost of a sandwich ranges beyond $0.50 to $200.00. It depends on the sandwich adds about as much to the conversation as "it costs less than a sandwich".
And to be clear by "beyond" I mean some sandwiches cost less than $0.50, and some sandwiches cost more than $200.00
Piling on the "some parts of 4chan was good until it wasn't" theme: I really liked /ck/ for a while. Then there was this weird trend of just like "all food tubers are garbage" whether that was "Kenji-Cucks", or people hating on Rageusa, or what ever.
Combining that with the "post hands" request for a lot of food it was just an unpleasant community to participate it.
Weirdly trying to load the page right now I'm getting Connection timed out. Is hackernews ddosing 4chan? What a world.
/ck/ from around 2015 to hmm… maybe 2018-19 was pretty good, and probably my home board. Decent cook along threads (I hope Patti is doing ok), /ck/ challenge threads where there was some theme we had to follow and posts would get ranked… and of course the yearly lemon pig [1] threads. Sadly I guess fast food posting, shitting on foodtubers, and general /pol/ shittery made it go down in my view. Still went there most days until yesterday though.
It would be nice to limit the YouTube content a bit like not just news, but an option for news in slow French, or something else. At least for me news in slow French is way easier to understand than news in French at 0.5x in you tube.
Maybe it's just my phone, but the dragging and dropping wasn't hit or miss it was mostly broken. On an English speaking video (my native language) filling in three gaps took me like five video repetitions to get the words in place. It made me feel a lot better about my Spanish speaking performance. Just clicking the words like someone else suggested would solve the problem completely for me, but it might be like a "hit box" problem on the words.
I mean if starting from scratch that seems like many years in most western education systems to get to probability, logarithms, exponentiation.
I would say If you knew 2+2=4, and not much else you're years away from 'understanding', if you know ln(exp(y)) = y, and P(x>0.5) = 0.5 for a uniform distribution on [0, 1) then you don't need any additional understanding.
I would bet the GP comment is somewhere inbetween the two extremes, but I think a random sampling of the population would likely result in people generally not knowing the log / exponentiation relation, or anything about the uniform distribution.
For me it feels like Stokers dracula is only so popular because it's where all the tropes come from, not because it's particularly well written, or something like that.
It's one of those firsts that established a genre.
I know Stoker didn't invent vampires, but they came into western English speaking culture through his Dracula.
I am not a literary critic, but I very much enjoyed Dracula. When I read it, I did not know there were claims he wasn't a good writer, so I had no bias, I simply liked it quite a bit.
I think that's classic chicken and egg. I've read it a few times over the years. It's a good story and fairly well written. And it obviously inspired movies and countless other works early on (as early as the 1920s). I don't think it has really been surpassed by other books or authors. Though there certainly have been some good ones. It both defines and leads the genre. Despite generations of literary critics trying to deconstruct and dismiss it, nobody has really done a better vampire story.
Thematically it is of course a dogs breakfast of repressed sexuality, homosexuality, etc. All of which were taboo topics in the Victorian age. Which is precisely why the story works so well. And even today it still works. If you can get over the Victorian era biases, it's a surprisingly fresh and modern story. Which is why modern takes on the story are still interesting.
And of course, these topics are still playing a role. Just look at the current election round in the US where things like abortion and gay rights are still being challenged. And it's not just the US where these topics are used by populist politicians to gain votes.
I don't know, Stroker does some interesting stuff in Dracula, essentially it's this Victorian hysterical story about extramarital or premarital sex "ruining" women (in this cases, essentially turning them into undead monsters as an extended metaphor for a woman's reputation being ruined in victorian society) as the cuckolded Victorian gentleman look in horror until they figure out the source of the trouble-- a no good foreigner.
There's also a sub-theme of the too secular modern men who don't believe in superstition (Jonathan Harker doesn't believe in vampires in the beginning) needing to get in better touch with Christianity to defeat Dracula- and features a rejection of secular psychiatry to defeat what turns out to not be "mental illness" way before The Exorcist did it.
It took me nearly 50 years before I learned how thoroughly gay Dracula really was. It was, of course, replete with coded references, and couldn't overtly depict homosexuality, so it was with Oscar Wilde, such as The Importance of Being Earnest.
Sadly I had really bought into the vampire chic trend when Coppola's Dracula came out in the early 90s. I had my dentist create some fangs for me to wear. More than one woman formally requested me to bite them on the neck. I dressed for goth clubs, more or less like an Anne Rice vampire (another thoroughly gay mythos).
It wasn't until Stephenie Meyer claimed vampires for the Latter-Day Saints movement that those Twilight sparkling dudes could be considered thoroughly hetero.
Yes! Now we are getting on to the true cost of advanced tickets.
Fines for making mistakes, rebooking fees, rebooking and having to pay a higher fare, lost tickets because sometimes it's just easier to book a new ticket, losing out when unwell etc...
I bet they make a tidy sum from unused advance tickets
(Great Britain specific):
Although worth noting when it's out of your control the railway does have to offer you options. You don't have 100% of the liability.
And if your train is cancelled you're entitled to take the one before/after for example or get a refund
Something like 15% of the world lives in extreme poverty. This is darn near the best it's been in the history of the world (there used to be much more poverty by percentage), but this group would likely have trouble being fit. They might be skinny, but surely not fit.
Ignoring that extreme the questions maybe different: How many hours does a median person have free from work, commute, and sleep? How much time must be spent managing exercise and diet to achieve fitness?
I think if you took the time to answer those questions for the median or modal non-impoverished person in the world you might find that fitness is actually quite difficult to achieve.
The work-life balance & climate in some areas of the US (and other areas of the world) does make it hard to exercise... but that's only part of the story.
Eating healthier requires very little extra time: perhaps 2-3 hours a week for shopping and meal prep.
- making a salad take 5 minutes.
- baking 10 meals worth of chicken takes 30-45 minutes, with about 5-10 minutes of actual prep time.
- baking a few meals worth of salmon, or some other fish is about the same as chicken.
- cutting up an apple takes 1-2 minutes. Bananas, peaches are ready to go, almost no prep required.
- steaming fresh broccoli takes 3-5 min of prep... and about 15-20 minutes total.
- Equally important is making small decisions to avoid or limit less healthy foods, which requires no time at all and often saves us money [that we can spend on healthier foods instead].
Exercising: 30-60 minutes a day, most days, is ideal but anything is better than nothing. A morning and evening 20 minute walk is great place to start (and can be so relaxing). If a person spends time on Hacker News, they could instead allocate that time to exercise. There are free 15 minutes yoga videos on Youtube. A set of push ups requires 60 seconds. Sometimes I do body weight squats at my desk at work (especially during Teams calls, camera off of course).
Sleep: get at least 7 hours of sleep a night... ideally starting to bed before 11pm. more sleep gives us more energy to put towards being awesome during the day and more energy for exercise and doing the extra work to eat better.
I think almost everyone can set aside 6-10 hours in their week towards building their health. It is a matter of priorities... a person's health should be one of their top priorities.
Parent poster wasn't referring to Ozempic but a general healthy lifestyle. Which requires resources many people do not have such as time, money, education etc.
