On the contrary. If life started multiple times on earth competitive exclusion probably took care of all other primitive forms rapidly. Even small differences, energy efficiency and reproduction lead to situation where only one form of primitive life survives.

Once the life really started going, it changed the chemistry of the earth rapidly. Similar chemical evolution starting from scratch was not possible once the life started.
Eventually when photosynthesis started, biologically induced molecular oxygen caused so called Oxygen Catastrophe where Earth's chemistry turned from reducing into oxidizing. Oxygen also changed the chemistry in the seas and rocks. Molecular oxygen is great disinfectant.

It's naive to believe AB resistance is only/mostly created in agriculture.

There is no evidence to that. Even the existence of resistant bacteria in agricultural animals doesn't prove there is a danger for Humans.

In Human tuberculosis for example, resistance seems to happen de novo in Humans, normally, after the patients go through multiple ineffective or aborted rounds of treatment.
Slow == performance left on the table.

The namenode is a threaded model with a lot of locks for each operation. This will improve with moving to Ozone and RocksDB under the hood (because Rocks doesn't leave much performance on the table). But it runs a lot of threads which can cause a lot of context switches.

The RPC uses protobuf which is cpu intensive so that's stealing from your RPS (which matters if you want to process multiple tens of thousands of requests per second).

Finally it's using Java and when you want to scale your namenode beyond 16GB heap then, afaik, you run into GC issues. If it were written in a non GC language then the namenode could scale a lot further. The memory size isn't helped by having bloated types passed around. One exmaple is UUIDs as strings all over the place because Java doesn't have a u128 native type. So you have 36 bytes for the UUID string and ~32 bytes of Java object overhead (though the JVM can unbox - it's not really something you should rely on magically happening).

Aside from all this (which are things that are baked in and will never change) Hops demonstrates there there's a lot of performance available in HDFS. But comparing XFS on MySQL to HDFS on NDB isn't really the same thing.
Yes, it resolves the issue in practice. However, the issue is an implementation detail of the compiler, not of the floating point format itself.
That’s actually not the case. Historically, low amounts of RAM and IO were the bottlenecks, we’re talking quad-core arm-v8 with a pretty beefy vector gpu/coprocessor.
I have had bad experience with Chromecast. I used to be able to cast by mobile phone to the TV to watch videos. But after some software update the casting would no longer work because I was using mobile data and mobile hotspot. Something which used to work when I bought the product stopped working after a software update.
Also there used to be a dedicated chrome cast app - but they replaced it with Google home app which has countless things I do not need. Also the home app is more flaky than the older dedicated app.
My confidence in google related have gone down rapidly and I am no longer willing to adapt new google products and ma planning to move away from what I am currently using.
Correct.

Probably can even configure local network file servers, but better if not.

If we don't ever need to use domains in the mesh (we have a separate directory / search system).

Wait, I only have to have the certs locally (offline) on the routers?

Ahh, hmm, cause you're saying I could MITM it. But Browsers (especially on mobile) all usually freak out when they go to `https://subnetIPaddress` saying "your connection is not private" "back to safety" every single time, with freakishly small "prcooed anyways" links on mobile. Either way, mobile or not, this warning totally just trashes the experience. How do I fix that?

Or you're saying they still type in the domain? But doesn't that require existing internet to then go through? Or you're saying, router still MITM that, but happens to have matching private key, so then it is able to locally (offline) proxy the traffic into the mesh? Hmmmmmmmmmmm!!!! This might be very helpful. Sucks we still have to buy certs to run our own offline system - who has the longest certs? (Let's Encrypt is like only 3 months?)

I'm ok with taxing flights if we also tax pretty much everything else for the environmental externalities of it. My problem is when countries/politicians/ordinary people choose one or two items that don't fully affect them and try to lecture others about it. (not saying it is your case, just in general).

And for my case, it is about 4 flights a week (both ways * 2). It may not be much, but is an extra 25 euros per month. Will this make me stop flying? Not really, but I will be pretty sour about it so I don't see how it offsets anything (but to be fair, us Europeans are already used to be heavily taxed in pretty much everything, and while I won't really feel the cost of the 25 euros, others will, see yellow jackets and the gas tax). And I pay for my work flights since I work for myself ;)

For you to get an idea, I just checked flights for September and I can do a return flight for 36.97 euros and will take me 50 minutes (+ airport time, which is about 1 hour for me). Same trip by train is 5h50 and costs 64 euros (on promotion, regular price is 105 euros.

ps: I hate flying and travelling. I do it because I need to.
"just open a .html file and start playing" is a route to making web pages, not get people into programming.

If they do want to get into programming, Scratch and other learning DEs and/or node/js are much better paths than dealing with the layers of barnacles that have accrued over HTML to get to the OPA / Webasm / TS/JS etc "web programming" environments.

.NET and VSCode are free downloads, provide a managed environment, and C# is a good imperative language to start with. It also supports F# if you want to get into functional programming.
I think if you run for POTUS, you're explicitly acknowledging that there will be constant public criticism etc. and that you do accept those as part of the job.

That's not how it's written in the post though. If you just swap out the "inertial mass" at the end and the "rest energy" somewhere in the middle it makes more sense:

> because photons have rest energy (=> kinetic energy) that can be viewed as mass in special relativity
> [...]
> impact the gravitational field despite having no inertial mass (=> rest mass)!

Speaking of "mass" in context of relativity is always a bit tricky. The term "inertial mass" for example is really saying something about how an object behaves under the influence of a force (F = ma), not how it behaves relativistically (that would be "relativistic mass", E = mc2).

This ruling doesn't affect what Twitter can do, only what the US government and its officials can do.
Tyler Rogoway just keeps writing these fantasy UFO articles and people just refuse to read the articles that debunked the findings.
See the circuit diagram above labeled "Excerpt from the reduced Pi4 Model B schematics..." that appears above the spec diagram? That is what I mean by a "conventional" diagram. That is the sort of diagram that people tasked with engineering boards (as opposed to writing standards) are use to dealing with all day. The spec diagram looks like an abstract block diagram, as opposed to a concrete circuit.

Now, you are very likely to say something like "but the spec diagram is a correct circuit diagram and the engineer should be expected to comprehend and correctly implement a circuit using it." And you're not wrong. But unfortunately, as is clearly evident by the frequency of failure to convey the intent of the spec, this expectation is too great. It shouldn't be but it is. That's a difficult thing to accept. For many it is simply impossible to accept. But yet that's the cold, simple truth and standing on ceremony doesn't change it.

When it costs money, in the form of lost sales due to disappointed customers or excessive support costs, "better" (as in more concrete, prescriptive) circuit diagrams are provided. One can see this in the datasheets and application notes from successful component manufacturers. They do this because they have to take the calls when engineers misunderstand things or need their hand held. They do this because they hear from managers and executives when their products are not "easy" to integrate.

Standards authors don't feel this pressure, so the subtle and easily dismissed gap between what appears in standards documents and what people actually want (and therefore pay attention to) is wider. What is wanted is something that appears nearly indistinguishable from what the engineer would expect to see while using Altium or Eagle or KiCad or some other commonly used EDA tool, and not a specification sufficient generalization.
If the droplet of sweat has a resistance of 10 Ohms, 1.2 Amps will be flowing at 12V. The droplet will be heated by 14 Watts of energy. Doesn't sound much. But it's enough to bring a droplet of sweat to the boiling point within 10 seconds.

Your sweat starting to boil of your skin doesn't sound like a very pleasant way to pass the time.

No, no, no: we're to bow before our strange new algorithmic overlords.
The misdirection would only work until someone actually read it and pointed the nonsense out, though. If it were actually intended to fool someone, it would probably be less obviously wrong. A patent for something feasibly advanced but not too out of the ordinary, or something hidden as a red herring in an actual classified document intended to be intercepted. I have a hard time believing a foreign government would waste a significant amount of time and money on American patents on woo-woo antigravity and things.

In another thread, I thought it could just be someone trolling the patent office, but I don't know.

Rumors are a new mbpro is coming this fall. Or next year. So I guess about four to five years or so. It makes sense that they ditched the regular mb because it was garbage. You may be right, and I hope you are, but I doubt it. If they were correcting course why not ditch the touch bar for function keys instead of the other way around? They have both. Their software choices also point to the same thing with sip, their slow phasing out of apps not signed by Apple, and the increasing difficulty in installing and running any other OSes on their hardware, especially new hardware. Even if the new mbpro comes out this year or next with a new redesign, I wouldn't hold my breath that it would be better. It's likely to be worse given so many years of bad design and ideas not only in laptops but in all their products. They are literally making computers for computer illiterate people these days. That's great for the masses who can afford them. It's great for a phone that has very limited functionality and use cases as smart phones tend to have. It's terrible for an alleged general purpose computer.

3.) Unless it's extremely unethical -- if it's just hurting my ego, but not actually my person and my ability to sleep well for the rest of my life -- I would do the stupid thing, but tell anyone who asks (and some who don't) that I find it stupid. I'd also start openly musing about what will come after the honeymoon phase (of the VP with their stupid idea), and how the mess might be fixed once it's correctly recognized as a mess. If applicable, I might also be honest to the people who get bitten by that stupid change. Not sharing the interna of the stupid decision, but that it's definitely stupid and why. If I got fired for any of that, I'd walk out like a champ.

I don't backstab, but I also don't lie (which includes people I'm "supposed" to sell the stupid idea to as a great one, starting with myself), I respect the "chain of command" in a way, but never blindly, and wear that on my sleeve. That closes plenty doors, but far from all, and my general experiences with "standing up to my bosses" were surprisingly good. As long as it's because you care about the thing, and the clients of it, and as long as the boss is confident, in themselves and maybe even you, there should be some leeway for that.
> A lot of people don't realize how hard these things can be. Having nothing to do or only meaningless tasks makes you depressed really quickly. Having suffered it for 2 years, I think most people don't understand how difficult it can be.

Yeah. Most people think "what's so bad about free time at work" - Sure, a few days of nothing to do sounds great .. but then the days become weeks, then month and every time you ask "Nope. Nothing to do." and at some point the realization sinks in that this is what you will do a good part of your waking day until the end of your life if you do not get out there. But you have liabilities. People depend on you. You cannot just quit, right? You have to suck it up? And so on. It's easy to say "quit being dramatic" if you haven't been affected by it.

Isn't this coming back to your point? If you are fighting an insurrection, and start acquiring resources by force, you are losing the will of the people.
At some point, your insurrection is just thuggery, returning to the point that guns only benifit criminals.

> It makes it more dangerous for corrupt police to sneak around like criminals without announcing themselves or outright lynch people in the streets, because it leaves people more ability to defend themselves against petty local tyranny as well.

History shows the police murdering people in the street because they happen to have guns. But since they fire dozens of shots against sleeping targets, having guns for defence never helps, and gets you branded as cop killer.

> And the obsession with the AR-15 is wholly misplaced. It's used by some bad people because it's used by a lot of people in general. It's popular.

Completely agree, it's just an example. A gun is a gun.

For people who know what they are doing, Bitcoin provides a new way to move money across borders. Almost always, the fees will be lower than they would with any other money transfer service. Most money transfer services will also have KYC policies which closely mirror what is required at crypto exchanges.

You only need to hold Bitcoin for ~1 hour total in the entire process. You can avoid making international wires by using domestic payment systems on each end of the transaction. If you do some research, you may be able to move money across borders and actually make a small profit of 3-4%, depending on the sending / receiving currency.

All said and done, Bitcoin allows people to have much greater control of their money. It is very useful for moving money between countries without subjecting yourself to the wait times and high fees associated with cross-border transactions.

Doesn't matter - god doesn't either. That's why it is running this experiment :-)

Seriously, since when did anyone ever understood the impact of anything? What the long-term impact of any new development or invention would be? Apart from running the experiment. Unless it is something very specific I don't see how this ever is a valid argument. Had we stayed in the trees we would have to deal with other issues and felt no better.
