People use Telegram because they have a great user experience. Signal, unfortunately, does not - and it's not entirely because they're limited by E2EE.

It is particularly amusing that they provided the two date/time pairs in the form of "Unix millis" only. Obviously there's the legal risk of getting the conversion to Gregorian wrong, but I suspect that may have cause some head-scratching at the court.
> How are you getting enough RoR experts?

This is very interesting. At my company we've had problems with finding senior Rails devs, which constrasts with the "great resignation" theory.

I think that the pool of senior RoR devs is restricting nowadays (due to the framework/language's loss of appeal), but the is a small number of Rails big techs (and famous companies, including 37signals) that are still very desirable, so they may not have problems in finding candidates.

I have to say I really like Python's module system. Modules as objects, scoped import by default and filesystem-backed module resolution (+sys.path) are all good choices in my opinion. Cosmetic warts like __pycache__ are unfortunate, but not deal-breakers.

Unfortunately, other sources of fossil fuel extraction have only grown in the US:

Looking at that graph, it looks like a mirror: the more coal decreased recently, the more other fossil fuel extraction increased. This goes back to my original point: The rate of fossil fuel extraction is the only metric that matters. And it's not going down in any meaningful way, is it? Hopefully soon, but I'm doubtful.

I admire Elon Musk as a visionary and engineer.

But here, I think, he is just trying to get out of the deal.

The high percentage of bots was exactly the reason why he wanted to buy Twitter in the first place. Because removing the bots would have been a relatively straight-forward way of increasing Twitter's valuation. IIRC he even tweeted about it.

[See my clarification below in a comment]
We could... but is it a good idea?
Drug abuse should not be treated as the cause of such a problem in our society.
I can’t speak from direct experience with Russians, but I’d bet they’re pretty good at it, as effective artillery fire (aside from target locating) is really more of a function of training rather than technology. For FiSTers though, it’s different. They have some truly impressive (albeit heavy) tech that can be used to spot targets from a pretty long distance. I so although any FiSTer worth their paycheck can call in fire with a map and compass, there is useful tech for them to get the target location to the guns.

> EXCEEDS the CO2 output from the gasoline truck over most of its lifetime.

The combustion of a gas plant or of a coal plant is more efficient than the combustion happening in a internal combustion engine, a turbine on a gas power plant can reach 44 to 60%[1] , a thermal plant 33% to 49%, an internal gasoline combustion engine tops at 35% in an idealized state, which real performance between 20 and 29%

Unless you have got strong metrics which quantitatively show this to be true, then it is not a claim that can be spouted easily

The right answer is to focus on what is possible in your jurisdiction.
> The most highly radioactive waste, mainly spent fuel, will have to be isolated in deep-mined geologic repositories for hundreds of thousands of years

that is false. High radioactivity means a very short half life. You only need to store such things for a few seconds before they degrade into something else - normally something with a much longer half life.

The really bad stuff is only somewhat radioactive: enough to be dangerous, but degrades over a few ten thousand years. There are a lot of atoms in even a small thing, and so even with half life in the tousands of years range odds are still high that several atoms in a bunch will degrade at anytime, enough to push radiation above background levels. Of course things go through many cycles of decay before they become safe.
I think Clubhouse was perhaps another VC pump and dump. Not necessarily deliberate, but that general flavour of startup that investors hoped to massive inflate and grab market share, with the expectation that there is some early mover advantage to be had in a new category. But because they were only manufacturing demand, rather than creating something people really wanted, it's just not worked out.

> so many tables

?

There are various complaints about OSM data model but this is a new one to me. In OSM basically everything is mixed together and there is no real separation into layers.

What you mean by "many tables"?
because this location is so accessible and not already melting fast enough?!
Seems like he's looking for a tactical retreat — the bots question is hyper-subjective, and provides the company a lot of wiggle-room.

How many Twitter accounts were created in automated fashion, but designed to look authentic, and haven't yet been removed by anti-spam measures? That could conceivably be around 5% of active accounts if Twitter is doing its job.

If you wanted to inflate that number you could include account takeovers, which are a little harder to measure (created by a real person, but taken over by a botnet using hacked/easy-to-guess credentials).

And if you want to inflate the number further, don't just count account numbers — instead look at the % of total activity (likes, retweets, follows) that those accounts represent. You can reasonably expect that number to be higher, given how many dormant accounts Twitter has.

Elon has alleged that his followers include lots of bots. That's not necessarily surprising as "follow Elon's account" is the sort of thing a bot developer might program in to look authentic.
That's the point of O-notation though. It helps you know how your computation will degrade as your data grows.

So you start with benchmarking your current data. You still need to always think about how your data will grow.
Unix time is the real universal date format surely? It underpins basically everything in datetime database entries.

Salt water is awful and underwater construction is really expensive.
One can "get started" with unpredictable renewables, and they are certainly extremely beneficial as they displace fossil fuels in the generation mix. 10% or 30% of yearly energy coming from renewables is great already. Some gas or hydro that has already been built can be used to flatten the worst peaks and valleys etc.

But once renewables go to higher percentages, the issues get worse. The main problem is that energy storage is currently very expensive and still dependent on geography (hydro power). So the electricity price will crash when it's very sunny or windy. That hurts the profitability of solar or wind power.

Like you mentioned, we would need to invest hugely in long distance ultra high voltage transmission lines, load buffering like green hydrogen for steel making, green concrete etc and maybe ultimately even batteries. These are large investments. Changing from fossil fuels takes a lot of money. The steel produced this way is more expensive than coal or natural gas based steel.

So renewables have a compensating effect. On the other hand as technology develops, they get cheaper - but when their penetration increases, they also become more expensive since they require bigger infrastructure changes.

Yet we still need to do this one way or another. Your new car or house will be smaller and more expensive because of it. Your electricity or heating bill will be more. The sooner we admit that yes, it will cause a lower material standard of living in the short term, but we still need to do it for the long term, the further we get.
> We can also talk about metaphysics: meta being Greek for “beyond”. This is where science meets philosophy, where we might try to identify underlying principles of reality that go beyond standard physics. Theories of time and space, of causality and determinism, of the nature of existence itself.

The etymology of the word "metaphysics" is more complex. The word was at first only a simple bibliographical ordering term denoting those works of Aristotle which were sorted into the Aristotelian corpus "after" ("meta") his works on physics (propably two centuries after they had been written). Aristotle himself never used the word metaphysics (his term was "first philosophy"). It had then been later philosophers who assigned a deeper meaning to "metaphysics". However, theories of time and space, and to some extent[1] also of causality and determinism are still part of "phsics", not of "metaphysics".

But leaving etymology aside, I have a deeper discomfort of the article's use of "metaphysics". Except from a few remarks, the article is primarily concerned with game lore. That is something that is much closer to (religious?) mythology than to philosophical metaphysics.[2]

[1] Causality, for example, is discussed primarily in Aristotle's "physics", not so much in his metaphysical writings.

[2] Not that religion and philosophy are complete antagonists, but when it comes to literary genre mythology and philosophy are quite distinct.
This is similar to the paradox of voting [1], and it is an important reason why many people don’t do as much, if anything. It depends on the individual’s psychology whether taking such measures are meaningfully beneficial for them personally (as opposed to for society).

I don't know much about this specific situation, but isn't it pretty normal to lock in a price for purchase contingent on everything checking out.

It's not like you can go digging around in their databases looking for bot accounts until you have official access.

EDIT: Clearly people feel strongly about this so feel free to look at the comments below for some great answers. I'd ask for you to read before commenting though. I keep getting emails rehashing similar things.
We stop extracting it and we're back in the 19th century. The whole economy runs on the stuff. From energy extraction to product development involving anything made of plastic. That's not going to change any time soon. That's the cold hard fact. We are already starting to see some of the consequences of scarcity of energy in farmers not being able to get enough fertilizer to grow the crops. The Ukraine crisis is largely about energy availability which could lead to 100 million people in Africa and elsewhere facing food shortages. These policy changes have consequences.
So utterly tired of this man. We all knew he would do this. He's the person that buys some expensive item he knows he won't keep at a store and returns it, causing headaches for everyone associated with it and him.
The sentiment I've seen is that a great people manager who trusts their engineers despite not knowing much about software can still be an above average manager.

Given that the median manager seems to be throughly mediocre, an above average manager even if they can't code or read code seems desirable.
We can't even reward people correctly for effort in the real world, that's why you need to spend time marketing your success on top of the actual effort of doing them, and why people are so wedded to hours spent on task rather than any real life metric of success.

> eli5 metaprogramming

Metaprogramming is "programming programming". Consider "programming" as writing a series of steps for a computer to follow. Metaprogramming is writing a series of steps for a computer to follow to write a series of steps for a computer to follow.

When working with LISP, metaprogramming is just a normal way to program things that's built into the language. Rather than writing everything as a linear program as you would in conventional languages, you can write a program that "writes itself" (or modifies parts of itself).

While you could meta-program in many languages (using code generators and whatnot), in LISP this is easy because the programs themselves are written in a way that makes them easy to be manipulated by other parts of the program. This is why you'll see so many parentheses when looking at LISP code. The simplicity of the syntax is also what makes it so powerful.

Metaprogramming is a technique that often results in much shorter programs which can make single programmers very effective. The downside is that the higher level of abstraction (leaving ELI5 zone here, sorry) can make the workings of LISP programs quite opaque to newcomers as things seem a lot like magic. Therefore preserving the metaprogramming advantages in larger teams requires _especially_ good documentation and attention to design.
It's just silly though -- he complained relentlessly about the bots before he made what was am unconditional offer to buy the company. Twitter hasn't changed their definition of bot in the past decade, they have repeatedly emphasized that they count them in a unique and specific way, and they detailed that methodology (it's not 5% of accounts - it's 5% of "monetizable daily active users"[1]). He has no legal leg to stand on, in a 'legally just' world, he'd be forced to buy Twitter for the price he initially offered. There's a good chance that the entire process would annoy everyone to death, so they may not try and force him to buy a company he no longer wants, but they'd be well within their contractual rights to do so.

[1] From their 2022 10K: We define mDAU as people, organizations, or other accounts who logged in or were otherwise authenticated and accessed Twitter on any given day through twitter.com, Twitter applications that are able to show ads, or paid Twitter products, including subscriptions. Average mDAU for a period represents the number of mDAU on each day of such period divided by the number of days for such period. Changes in mDAU are a measure of changes in the size of our daily logged in or otherwise authenticated active total accounts. To calculate the year-over-year change in mDAU, we subtract the average mDAU for the three month sended in the previous year from the average mDAU for the same three months ended in the current year and divide the result by the average mDAU for the three months ended in the previous year. Additionally, our calculation of mDAU is not based on any standardized industry methodology and is not necessarily calculated in the same manner or comparable to similarly titled measures presented by other companies. Similarly, our measures of mDAU growth and engagement may differ from estimates published by third parties or from similarly-titled metrics of our competitors due to differences in methodology.

We again return to the rabbit hole that is the Fermi Paradox [1]. In short: there are so many stars and planets and we've had billions of years. Why aren't ther emore signs of technological life?

A core idea of this is that there are various filters that separate a new planet from one hosting spacefaring life. There are lot of these filters proposed. One category is the Great Filter. These are where very few lifeforms are expected to pass.

So what we're talking about here is an early filter where a planet forms in a relatively stable and suitable star system and single cellular life forms. Based on our own understanding of biochemistry, that pretty much requires amino acids. Now there might be other forms of life out there but they're all theoretical. We have one which is real (ie ours).

We've had a lot of experimentals that show that amino acids can form in deep space on icy bodies. What we have here is direct evidence from an essentially random asteroid that it has amino acids on it. We can and will speculate as to the origins of these. Did they form on the asteroid? Elsewhere? When?

You can't obviously draw too many conclusions from a single data point but to suggest we got extremely lucky to find the a super rare asteroid with amino acids on it stretches incredulity.

So the conditions that lead to life similar to ours forming being relatively common only gets stronger. This is similar to the number of expoplanets we've found. We've shown that planetary systems are exceedingly common, which was something we could only speculate about a mere 40 years ago.

More planets, more conditions for life forming. This means more species are likely getting filtered further down the chain.

If you sell your company, presumably you don't care about its future success anymore and now you have a bunch of money with which you can do whatever you want.
On another note, isn't it amazing how well Twitter hides its advanced search functionality? I still don't understand if it is incompetence or deliberate.
Yes, but sufficiently high amount could potentially mean lower price. So it serves as a way to keep his options open and an indication to counter-party that he could just walk away.

As much as Elon annoys me, it hard for me to say he does not know what he is doing. Even the WFH tweet was timed seemingly to lower the cost of severance payments from announced 10% workforce reduction.
Erm, "I think the terrorist issue is an overblown boogeyman" is cold comfort. ISIS already comtemplated building dirty bombs in Mossul.

And so far most of the nuclear waste has been stored right were it was used. SMRs are supposed to be everywhere. So nuclear waste will be everywhere, ready to get stolen, or shot at or blown up.
Why is Twitter not providing this data? It’s a straightforward request and it’s not like he would disclose it publicly. It feels like Twitter is trying to get out of the sale by using loopholes, this is very strange.

Another great one was Jon Eats Carrots, which was a fisheye lens of a man eating carrots for 10-20 minutes at a time. He did hundreds. He also did a series on him counting to 100,000.

Also Bryan Ropar has a channel where he talks about his favourite plastic outdoor chairs - he has over 600 of them now (videos that is, probably more chairs).

Youtube is a wonderful place.
Because there is no attention in due diligence relative to the amount of attention he gets saying "I'm buying Twitter!"
He might actually have to make this deal. I thought for a while that he had no intention of actually buying them. He just wanted to stir the pot with Twitter. He would then back out, and say something like "Taking these funds and now putting them towards a moon base to mine helium 3 operational by 2023" and people would eat it up. But I think now that it didn't work the way he planned, and now his credibility and ability to make sound judgements is being questioned by many.
That is absolutely not my experience of YouTube, where every video I see on my feed is about retro tech. Not exactly “big media” material.
