I thought that maybe there could be something particular to how rockets work which would cause economies-of-scale to be irrelevant in the case of rockets, and so a bigger rocket wouldn't necessarily deliver a payload more efficiently (per kilogram).

Besides that though, I was also thinking about the ultimate goal of these companies. Presumably, both SpaceX and Rocket Labs (and others) want launching rockets to become a much more common day-to-day activity than it is now.

At that point, would it not be better for us to focus on bigger rockets to ensure that we're not creating unnecessary pollution with smaller rockets? Kinda the difference we could've made if the US for example had focused on large-scale public transit rather than urban sprawls where everyone has their own car. If we have the option now, it seems to be like we should push for the large-scale more efficient solutions now so that it doesn't come back to bite us later.
It made it to orbit, but it was highly eliptical. They put it into an 180 km × 1500 km orbit with 31° inclination. It had a lifetime of about 6 months before re-entering.
Bandwidth is usually less of a problem than latency.
Yeah sure so what. All that rationalization is out the window if they just cut someone off like that without actually communicating those reasons.

The reason I take exception to it is that the concept of shadowbanning is deeply baked into the SV/startup culture and it's very often completely unethical. It's a pet peeve of mine.

Sure, if you're trying to stop forum spam then who cares. And I do understand that when startups were small they were incredibly vulnerable to just being overwhelmed by an avalanche of fraud. So historically, I get why there's a culture where platforms just ban or restrict people without telling them comes from.

But one thing SV has been enormously bad at is not realizing that they aren't feisty underdogs any more, they're the ruling class, and they often have tremendous economic power over people. When people depend on you for their livelihood, or for transportation or housing or similar, then you actually do owe them transparency and an explanation of what's going on.

I'll have to play around with laravel / php / vue more to see what I like. NodeJS is great and all, but it's not opinionated with it's frameworks. Too many ways of doing things. I want to build shitty prototypes quickly with a slow moving but well established framework

I like rails because it has a singular mindset. I'll have to give laravel a try.

That's not the case. You must anyways be able to support them to get anything done so the software things already exist.

It's just that they don't bother with sharing those docs in English since it's Asia only pretty much.
Yeah, that's interesting.

We start with approximately 33 bits needed to uniquely identify her. She lives in Havana, which immediately slices 11 bits from our search space (the population of Havana is around 2.13 million, or ~2^21). She's female, so we can roughly cut our population in half again; now we're only at 20 bits.

She worked in the Havana embassy in 2017 and was one of the people impacted by the strange health issues. There were about 24 people impacted (insofar as I can quickly find online), which means she must be one of these 24 people. Assuming all of the other 23 are also female, now there are only 4 bits remaining (24 = 2^4.58).

Finally, she has twin 12 year old children. We'll have to make a few fuzzy assumptions here, but given 1) a birth rate of ~1.5 per female per year, 2) a world female population of ~3,232,000,000 in 2005, and 3) a chance of having twins at about 3.33%, she is most likely in a set of about 159,984,000. This is only about 27 bits, which means we get a little over a 5 bit reduction by placing her in this set. That gives us the last 4 bits we need.

This is all assuming that the information given in this article is correct and the foregoing estimates are comparable to the real world statistics. This is a little fuzzy because I'm not sure if she's actually Cuban or American (and therefore where she was in 2005, or which estimates to use for calculating twin and birth rate statistics).

> SpaceX can take far more cargo to space, but Rocket Lab is pitching its nimbleness and low-cost as ways to give new customers access to space and to do so on a more convenient schedule.

Weren't small low-cost launches the original goal of SpaceX? I recall Elon saying there wasn't actually that much demand, which is why they were forced to scale up in the first place. Has the market changed recently for small low-cost launches?
In theory what could be done is (not saying anyone does this):

1. When you get cash from an ATM or Bank they record the serial numbers of the cash they gave you and attach it to your identity.

2. When you spend those funds at a store they record what you bought and the serial numbers of the cash you paid with and the serial numbers of the bills you received as change.

The government could then build a graph of spends attached to your identity. With high probability they could trace how you spent that money. One problem they would run into is if you gave or received cash from a friend. However while this might cause the tracing procedure to make some errors, it would also allow it to, in some cases, infer which of your friends you exchange cash with.

In any realistic scenario the government would also be intersecting this graph of spends with additional information such as license plate readers, RFID data from public transit, facial recognition,cell tower geolocation, etc... Serial number tracing would be just one data source.

Probably your best bet for privacy here would be pay people begging for money to swap bills with you e.g. exchanging a twenty dollar bill for a ten dollar bill.

This is so, so close to allow me to run a full local vim (with the necessary external tools, like python and git). The only thing I found that was a dealbreaker was the lack of unicode support (https://github.com/tbodt/ish/issues/28), and not being able to map caps-lock to escape.

For now, Nicolas Holzschuch's fork of iVim (https://github.com/holzschu/iVim) is still by far the best solution, but iSH definitely has the potential to take over.
My favorite thing about Rocket Lab is the rocket engine they use[1]. By replacing the turbopump with a electric motor they were able to remove one of the single most complicated and expensive parts of a rocket engine. As battery densities keep increasing we should see electrically fed engines being used on bigger and bigger rockets.

But not all tasks can be made bite-sized. Or more specifically, sometimes the bite-sized pieces aren't "complete enough" to be a valid unit of work to be nicely wrapped up and finished during a sprint.

What happens as a result, is that more major tasks never get sufficient priority to actually happen. This can easily lead to an incremental "refuctoring" of the code base, where you have a lot of individually-nice bite-sized tasks that, in aggregate, turn the source tree into a total mess.
Probably about that. CGP Grey has a great video about the whole YouTube system https://www.youtube.com/watch?v=KW0eUrUiyxo.
Hi irtefa,

Why does the Android app have 'Microphone > record audio' listed as a permission?
This kind of thinking has permeated my coding practice.

I used to think "this is hard, I need to learn about more systems until I'm smart enough to do this."

Now I think "this is hard, there's probably something wrong with the architecture. I'll fix it."
It's not at all surprising that red yeast rice would be as effective as a prescription drug in lowering triglycerides. In fact, "Some red yeast rice products contain large amounts of monacolin K, which is chemically identical to the active ingredient in the cholesterol-lowering drug lovastatin." (from https://nccih.nih.gov/health/redyeastrice)

It seems statins have serious side effects such as nerve damage, so perhaps you should go with the exact dosage prescribed by a doctor instead of taking an unknown quantity of the same drug from natural sources.
It's certainly a sign of an advanced civilization, but the practice has been around for a while. The Apollo 10 crafts were "Charlie Brown" and "Snoopy."

Taxpayers pay for the stadiums. The team threatens to leave the city if they don't.

Additionally, the NFL is a "non-profit" organization somehow!!

EDIT: Errrr it used to be tax exempt until Cory Booker made them cut the bull
It's very smooth, like Prince of Persia was on the C64. That games graphics/smooth animation really amazed me back then (mid 80s) and was unlike anything else at the time, really.
In the US, stadiums are often funded by the taxpayers of the city/county. City governments (although often not the populace) are frequently obsessed with having pro sports teams. It's common to plow hundreds of millions of dollars to build a stadium to either get a new team or convince an existing team to not relocate.

Supporters typically claim that the economic benefit of a sports team offsets this cost, but the benefit is in fact completely negligible or even negative.
I never say anything about d being even. Rather, as soon as d > 0, x{d} is even, so "almost all" x{d} are even. As you vary x and d, you cover all integers exactly once, so from this perspective, "almost all" integers are even.

My point is that this is very similar to how elliptic curves are being counted here.
I was once on a project where the managers loved it, because it gave them the ability to micro-manage a project like never before.
They got daily status meetings, and bi-weekly cycles to adjust things.
I started looking for remote software development work in March of this year. Due to being in school part-time I couldn't take a full-time gig. And I interviewed with three consulting firms that all wanted me to commit to over 30 hours a week.

Upwork turned out to be a good solution for me. It took about three weeks of searching through Upwork job posts until I found a good fit. There were a lot uninteresting job postings to wade through. And being new to the platform (without any history or earnings) probably made landing a job more difficult.

But I finally found a great client who allows for flexible hours at a pretty good hourly rate. Most of our team was found via Upwork and with only one exception everyone has worked out well.

The Upwork screenshot/work monitor software is definitely intrusive but I feel that's the cost of earning trust in an environment where clients and providers don't necessarily know one another.

Now that I've earned over $10k working for this client, Upwork is "only" taking 5% of my rate. However I feel this is quite fair given the platform they provide. Anyway a body shop would be taking a much bigger cut. I'm also building up a history within Upwork and future gigs should be easier to land.

Just as with other trust-based systems like Airbnb, the longer I'm on Upwork and the higher my reputation & earnings become, the more I'm incentivized to keep using it.
Falcon 9 burns trough around 500t of propellant while Electron trough around 12t. So, you need roughly 41 launches of Electron to match one of Falcon 9. 41 Electrons can deliver max 10t of payload costing around 246 millions $, while single Falcon 9 more than 20t in expendable version costing less than 100 millions $.

But the issue with big rockets is that they can take a payload to pretty much a single orbit. You will never find 41 clients that want to go the same orbit. So, quite often big rockets are flying below their max capacity.

Also, rockets contribution to humanity CO2 emission is close to zero. I would not be surprised if some launches of agricultural satellites had positive net impact on environment due to more efficient usage of water, fertilizers and pesticides that monitoring from space allows.

If F9 fired 100 times a year and converted 100% propellant mass into CO2 (it actually produces a lot of water) it would be 0.0001% of world emissions.
One thing that has been interesting to me owning an EV for about a year now is how charging and refueling create different needs.

With an EV I rarely need to charge when out and about, because I leave every morning at 100% charge. Those few times I do need to visit a charger it's generally for a full charge, so it'll take 20 minutes to an hour, so I'll much prefer charging stations at restaurants or grocery stores.

I think there will be a big market to reimagine the gas station concept into something more destination oriented, e.g. much more like truck stops, fewer in number but with more services.

Were more musicians earning a living then compared to now?
When was that? Since at least the 1960s, music has been a winner-take-all hit driven industry. You’re either The Rolling Stones, Motley Crue, Madonna, or at best a one-hit-wonder. The vast majority of bands are (and always have been) local groups who play their town bars, occasionally go on tour, and have day jobs.

I’m not saying this is good, but it’s the way things have always been. There was never some “good, honest living” to be made for anyone who isn’t a household name.
If the government wants to "unperson" someone, cash or no cash or electronic money, they will just come and collect you.

You having pieces of plastic/paper and/or metal trinkets in your pocket plays will not save you from this.

I understand the apparent privacy angle, but if you analyze it further, cash won't help in the presence of a malicious system. If the government cares enough about you to stop you from using e-cash/credit cards to buy or sell, they will also care enough to not let you roam free.
In my opinion this is a big argument in favor of the security benefits and update ability, if you're a company putting thousands of remotely managed devices out into the field, for using an x86-64 architecture. Yes it might be more costly and expensive to have NUC sized things, but you can also be confident that you can run a fully patched OS on it in 12 or 15 years from now. If I had a core 2 duo based 1U appliance from 2007 somewhere I could quite reliably update it to Debian 9.6 or the latest centos.

Yes, the smallsat market has grown immensely over the last decade.[0] The propagation of larger CubeSat standards and the advent of rideshare in particular have driven growth. Many companies (Rocket Lab, Virgin Orbit, Vector, Relativity...) are now betting that demand is sufficient to support at least a handful of dedicated smallsat launchers to avoid the hassles & delays that come from rideshare.

> And although her 1925 paper on autism traits appeared in German the following year, the translation butchered her name, misspelling it as "Ssucharewa."

I just want to note that the double s at the beginning is the only mistake in the different spelling. Maybe some would call that "butchering", but I think that's a bit harsh.

The ch and w are the normal German transcriptions of the Russian letters that get transcribed into English as kh and v, so they were appropriate for the German translation, but in English retranslations or reviews, such as this article, they should be retranscribed from the original.
Sure. But are these subsidies still needed? In any case, my proposal was more along the lines of an approach to unilaterally prevent companies from benefiting from off-shoring tax schemes, under the assumption you want to do that. The thing I want holes poked in is the scheme itself, since I'm taking as given that some people want to institute a scheme with this goal.

Sounds reasonable to me.

The company can't employ him for full-time work as a freelancer, due to regulations that protect workers rights. Whilst that might be a problem: it's like one person doesn't like it and millions need it to protect their livelihood.

Upwork wouldn't inform him because it's nothing to do with him, he's a freelancer not an employee (the reason for the whole issue). If he were an employee obviously payroll (who Upworks represent in this case) would have to give notice etc..

So, in part he's complaining about not getting the protections that a full-timer does - notification of change of work, conditions, hours and such - whilst simultaneously arguing that he should be released from those same protections.

I mean who wants holiday pay, sick pay, employer pension contributions, job security, etc. ...
Arguably $5000 isn't much for three years and 1 million plays, but I'm also not sure what they where expecting. I believe the issue is that Spotify charges customers per month, while artists are paid by play, so the more Spotifys customers use the service, the less they can afford to pay for each play.

Assuming that a consumer spent the money from a Spotify subscription on CDs instead that would, in Denmark, be around 24 CDs in a three year period. When you look at it that way, I can't really see how artists expect to make any real profit of Spotify, the money simply isn't there.

Streaming services allow consumers to listen to vastly more music that they ever did before, and from a larger number of artists, but at a lower price, so I can't see why people are surprised that Spotify isn't making them money.

What would be interesting to see is: How many time would a fan need to play songs from one artist to make the artist the same amount of money as the sale of a CD. I believe that an artist only makes around $0.5 from the sale of a CD, the rest goes to the label, promotion and so on. So I would assume that as long as each user plays a song around 100 times, the net result would be the same.
I'm not so sure. Why ?

Well, one way to conceptualize human needs is maslow's hierarchy. the final, LOWEST priority need is self-fulfillment. so there are many more pressing problems before that to solve.

but:

It says nowhere that self-fulfillment must be in your job.

Who says that being a successful musician is "the" useful trait to develop ? reading about successful musicians, and knowing one, they don't seem particularly psychologically healthy. Same goes for probably many other talents.

And who says the "self" is the key thing to develop anyway ? if you ask spiritual people, peak human development looks quite different.
been there.
landed a great job, loved the coding tasks, had great colleagues.
the office was an open-plan one.
seemed cold rightaway for me. sitting under a ventilation shaft, the cool air flowing was not pleasant but still liveable.
cold all day long but also sweating at the same time as the office didnt seem to have oxygen.
gasping out of a small kitchen window for air - one of few openable ones :)
did some air vents hacking.
4 months i start to feel weird. cold empassing my bladder, lower stomach. total allergy to any airflow.
took a -20 degree celsius sleeping bag to work. spending my days wrapped in it. didnt help. switching office desks to see if there's a chair i can sit at. the 40+ people in the open plan obviously see theres a nutcase in the building. my direct bosses are compassionate though. they see im not kidding. under-table-portable heating is suggested. geopathogenic zones are suggested existing in place. i go see doctors. im in pain, my bladder us killing me, doctors/urologists say everything is fine with me.
i cant drive the subway because theres draught.
i google sick building syndrome.
us this really hapenning ?
i quit.
they let me go rightaway (thx)
