Something I’d buy, and that the Raspberry Pi almost might have been, is a computer running a “retro OS” (instantly boots, BASIC-like commands, direct access to hardware) on a semi-modern ARM chip with a few megs of RAM and HDMI out. That would be fun to tinker with and program for.

The problem with this is that it’s so incredibly hard to do anything in 8-bit, I can’t imagine many people going to all that trouble if they’re not even getting the badge of honor if running on real retro hardware.

There is always a schema, and PlanetScale, in particular, promotes the use of schemas. That is, behind the scenes we operate Vitess, which is an infrastructure and sharding framework on top of MySQL. You will create schemas in PlanetScale just as you would in MySQL.
Managing the schema, though: operating schema changes in code and in production, mitigating schema conflicts, scheduling migrations, running online migrations, experimenting with schema changes, etc., are something relational databases don't provide the right (or any) tooling for developers, and this is one of the things PlanetScale aims to bring to developers.

In my past experience as a production engineer, and in our many discussions within the community, we've seen many approaches developers take just to avoid the hassle of running yet another ALTER TABLE; whether because it requires going through a different team, or because this poses an availability risk, etc. PlanetScale offers to bring ownership back in the developer's hands.

Hope this clarifies. We'll publish more soon, and I'll be able to provide more links.

In that sense it is not bad. The problem is that it creates perverse financial incentives for large sections of the population to be incarcerated as a cheap supply of labour. Prison labour also undercuts minimum wages in some cases. Consider that for-profit prison companies spend millions of dollars on lobbying efforts.

You can invite an experienced contractor that can help you with bootstrapping development: deciding on MVP tech stack, hiring, and making sure the new team can deliver proper work.

Sure, you need someone to refer a good contractor to you first, chicken-eggs problem.

I wonder if there are companies that can help with it as well - not shops that try to convince you to outsource the whole development to them.
I wonder if this has anything to do with recent Tether reserve report:

Since the report does not really specify what exactly the reserves are we can expect NYAG to not be happy with it, and taking further steps against Tether.

re. syncookies: Linux by default starts issuing syncookies when listening socket's backlog overflows, so it may be accidentally triggered even by a small connection spike. (This, of course, is not an excuse for a service misconfiguration but it is quite common: somaxconn on Linux before 5.4 used to be 128 and many services use the default.)

re: pacing: Awesome!! I would guess it is similar to Linux "internal implementation for pacing"[1]. Looking forward to it eventually graduating form being experimental! As a datapoint: enabling pacing on our Edge hosts (circa 2017) resulted in ~17% reduction in packet loss (w/ CUBIC) and even fully eliminated queue drops on our shallow-buffered routers. There were a couple of roadbumps (e.g. "tcp: do not pace pure ack packets"[2]) but Eric Dumazet fixed all of them very quickly.

> But the total number of people buying tickets is the same, all that's happen is it's being temporally shifted for the gain of the people that can afford to do so. This only works because the actual offered price of the tickets if far below that real cost people are willing to pay. If tickets were initially offered at an accurate price, there would be no money to be made buying them for resale (well, almost. There's still the option for artist demand to change over time with popularity).

"all" that's happening, no. Causing people to pay more, even if they're willing to pay more, means they get less benefit out of the transaction.

> Finally, there's events where there's a lot more consumers than there are tickets. Perhaps there weren't enough tickets at the sale day to sell out immediately. It would have sold out well before the event date though, because there are way more consumers than tickets. In this case, at that point liquidity would have dried up. Brokers provide liquidity over the lifetime of the event. That's what they provide, and for that they extract money. There's a debate to be had as to whether they provide enough value for that service, but it's false to say the event had "enough liquidity", as if there was enough liquidity there would be no margin for brokers to make money, especially not the 10% cost on sale price needed to make a profit on the exchanges.

There would have been enough liquidity for the people that cared about the event to be able to purchase. That's enough liquidity. There is more liquidity now, and the benefit is that some of the people who didn't care very much get tickets too. This is a benefit, but it's not worth the downsides that the average amount paid goes up so much and that a bunch of people that were ready to buy a ticket on day one are now excluded.
That's irrelevant. Being a high quality or popular product doesn't stop it being a commodity.

It's not religious. If anything the opposite is true. Believing we're the only intelligent life in the universe is an epic violation of the Copernican Principle.

There are so many other explanations for Fermi Silence - from the reality of extremely limited sampling to the creeping suspicion that we're too mediocre and underdeveloped to recognise truly intelligent life - that grand assumptions about our specialness seem more than a little premature.

None of this requires aliens who will teach us anything, one way or the other. It requires aliens who ignore us because we're about as interesting as a termite mound.

And once you've seen a few billion of those, you've more or less seen them all.
The effect of these non-news on the price has become a self-fullfiling prophecy.

People sell not because of the effect the change is going to have, but because they think people are gonna think the change is going to have an impact. Everyone thinks everyone else is gonna think that. Boom, dump.

Smart people get a golden opportunity to buy cheap while dumb people panic sell.
The problem is the incentives they create to imprison people.

Imprisoning someone should be a purely negative action on the state, by having some potential benefit you reduce the costs imposed to the state and therefore incentivize imprisonment.
The main issue with IOT is not coverage but the massive number of connected devices. 5G is designed to support this.

4G might have a larger coverage per cell, but if it isn't able to handle all the devices trying to connect then that means nothing at all.

5G can have comparable coverage, by the way.
It can go beyond hiring developers - companies may need help with deciding on initial MVP, organising development process, and regularly checking for a while if things go well.
Wow, this is a pretty ableist take. Deaf people or hard of hearing exist.

I do not understand why we would only be seeing UFOs at convenient airplane altitudes inside our atmosphere, but not detect them while they approach Earth, despite the fact that space is constantly being scanned for all kinds of stuff. I also don't understand why the daily UFOs would choose to just confuse us by flying around in a sorta-hidden but also sorta-not-hidden way. Why don't they interact with us if they go to the trouble of visiting?

Everything about UFOs is so implausible that the alternative explanation of "we don't know what we saw, but almost certainly not a UFO" seems to be much better.
Why would you need lightfields to make a TV that shows a different projection if you change vantagepoint?

TL;DR: "We don't know how often abiogenesis happens, and our uncertainty for its rate is extremely large. The error bars extend so far into 'effectively zero' that we could or could not be alone, it's a toss-up". Seriously, this paper hinges entirely on the prior distribution for the abiogenesis rate.

Longer comment:

The paper considers each parameter of the Drake as a probability distribution over some range. Notably, they assume that f_l in the Drake equation (the fraction of habitable planets that actually develop life) may vary over (at least) 200 orders of magnitude. Yes, you read that correctly.

Naturally, they thereby get a long tail of "planets essentially never develop life, even despite there being so many of them".

My main critique (as someone with no further credentials) is that the prior probability distributions they assume for the parameter distributions are more or less meaningless. Their results say "if we assume that the log of f_i (life-bearing planets that develop intelligent life) is uniformly distributed between log(0.001) and log(1), similar for other parameters, then the probability of being alone in the milky way is > 50%".

Specifically, by far the largest impact here is from assuming some distribution for f_l that covers 10x as many orders of magnitude (!) as the remaining parameters together. I'm very certain (but haven't done the math) that slightly tweaking the sigma they assume for the corresponding log-normal distribution (that sigma is 50 orders of magnitude) would drastically impact the results. They do a lot of dancing around that fact (discussing how little impact the priors of other parameters, or even the center of the log-normal distribution for f_l have), but fundamentally the result boils down to:

"We're extremely unsure how often abiogenesis happens, and this parameter dominates everything else." Followed by some math that (oversimplified) boils down to "if we set the rate of abiogenesis to effectively zero half the time, then half the time we are alone in the universe."

While I love, love, love retrocomputing I don't understand why 99% of it is "retro-next" computing - instead of designing computer from some era people like to design much beefier next-gen machines. 2MB of RAM? 640x480? Why not use Amiga instead? Designing a machine that would beat c64 is insanely appealing to me. Designing a machine that would beat c64 because it came out a decade later and had larger ram chips and much larger gate count in a video chip? Meh...
This notion that bitcoin is great for crimes has been thoroughly debunked in a variety of studies over the last few years. There's more crime committed using the US dollar (on a percentage basis even) than using bitcoin and the Bitcoin network's transparent nature coupled with the advance in on-chain analytics makes this easy to explain.
I feel like this article is pointing a gun at the wrong faces. These companies are most likely doing this as a form of social giving. The amounts involved are minuscule for the industry.

It touches on the question of rehabilitation but very superficially, when that should be the main point. Plenty of prison systems have voluntary work placement, not mandatory, and it benefits everyone.

Buried at the very end:

> In a series of interviews and surveys by the nonprofit Impact Justice for a six-part report on food in prisons, formerly incarcerated people reported widely varied experiences working in food production. In some cases, people said they received helpful training, enjoyed the fresh air, and snacked on food they grew. In other places, they found the jobs extremely difficult and were not allowed to eat the food they produced.

While a SAN/NAS is overall an expensive hardware in both price and manageability, there are entry level devices. You can even get direct SCSI devices in some cloud services(Azure has "shared disks"). For Oracle RAC the data is accessed from same location, it's not distributed/replicated across nodes. It's literally the same disks attached to all nodes. Also ASM works with raw block devices which bypasses the need for file system abstraction and all the latency that comes with it. You could also deploy a cluster on a cluster/network file system, but this would generally not be a good idea since you get a lot of overhead.

Postgre clusters can be configured in similar fashion.

I'm not saying that Mongo doesn't have it's strengths. However using the full potential of your environment requires much more planing and has a lot more pitfalls.

There is a large difference between having a decent grasp of the fundamentals, and being able to regurgitate parts from pure memory while being grilled by the interviewer in a high stress situation.

This article comes across as tone deaf and unsympathetic to me.

Also, a lot of the sentences on music here are just not right. Jazz musician/composer here, who knows most of what music theory there is to know in a few genres, which is not much. Most of the musical knowledge good musicians, improvising musicians at least, have, is private and unique to themselves, or stored in their bodies and muscle memory and even they don't "know" or understand it, they can just play. "Music theory" just doesn't take you very far at all. Shakespeare couldn't have explained what he was doing or how he did it, nor could Hendrix. They just could do it, natural as breathing, or like walking, which people can usually do without the help of theory or being able to explain how.

> Even though the person might not be composing their own songs, their understanding of how music works likely makes them extremely comfortable playing and improvising any kind of song.

Understanding music theory doesn't make you comfortable playing and improvising at all. Being able to play an instrument and improvise makes you comfortable doing that, which comes from doing them a lot.

> if the person doesn't know the theory, it's likely that these songs are going to be hilariously bad.

No, the songs of people who don't know music theory aren't hilariously bad.

> To make it worse, musical progression is not a thing you just come up with -- songs aren't random, the chords for each song have a theoretical relation to each other. Making a decent song is a science, and one can learn it by understanding the theory.

But a chord progression or melody or lyrics are often a thing people just come up with. Writing songs is in no way a science. You can't learn "making a decent song" by understanding music theory. The characteristic, memorable, wonderful moments in each song are usually the unique, irregular ones, about which there is no theory. Etc etc.

They don't work regardless of when deployed. The idea the UK was late is doing the rounds inside the UK establishment but it's wrong. If they worked places that stopped doing lockdowns would have seen huge surges and higher death rates than places that kept them, but that didn't happen and there are by now many such examples. Lockdowns don't work because (a) COVID doesn't seem to care about them and (b) COVID is nowhere near deadly enough to justify them, as demonstrated by the counter-example states and countries that rejected them and saw far less than the predicted mortality.

Well, thankfully we’re not doing that. If we’re advocating for prison work to become more healthy, that’s the wrong way to go - it’s transparency for the customer, but a form of discrimination for the workers.
