The "Fermi paradox" isn't meant to be an actual paradox in formal terms.

It is simply asking basically "if the universe is teeming with life, where is it?" and by that raising both the question of whether or not the universe actually is teeming with life, and if it is, why aren't they here? It reduces to an actual paradox only if you assume an answer to one part (the amount of life) that isn't reasonably compatible with the second part (why we haven't seen evidence of it) without a reasonable explanation.

That it simply on average takes too long for us to have seen evidence yet is in fact one of the many suggested solutions.

But overall the point of the Fermi paradox is that the problem if why we don't see aliens is two-pronged: They might never develop, or just not have developed yet, to a sufficient stage. But it's also possible they do, but that something else prevents them from contacting us.

Thus the idea of "great filters" for example. E.g. maybe the universe is full of life, but it's exceedingly rare for it to survive long enough to be able to make contact without being destroyed. Maybe the odds of getting killed off by asteroids is too high. Maybe war takes out most that get to a certain level. Maybe someone out there takes pot-shots at anyone sticking their head out? Maybe some galactic events sterilises large swathes of space too often? (intense gamma bursts have been raised as one possibility)

As well as many other options. E.g. maybe we're quarantined? Maybe we're in a simulation, and simulating aliens just isn't part of the program?
I like where this is going, but not sure of the practical use case. Can this help me inspect my game objects at runtime or just act like a standalone playground CLI?
big thanks. Actually I worked for Openstax (Connexions) in the past but I think I did not met Michael Harrison at my time :)) I will definitely give it a testrun!

Hi folks

Thanks for raising this. Many links are shareable and history-API friendly – e.g. direct video links, speaker links. (e.g. dev.tube/@eduardsi). Internal site-search is not History API friendly, though.

Any hints which parts of the product need better history support? Submit issue/feature request here:

I’ve mowed (personally and as a summer job when younger) for almost 40 years. Animals of all sorts seem to avoid the mower when already runnng.

As a kid, I gave our family cat a close scalping. It was late fall and we were picking up leaves with the mower. After a lunch break, I fired up the mower and the cat shot out from underneath making an awful noise and headed for the woods.

We assumed she was fatally injured until two/three days later when she came walking back up the sidewalk, sporting a close shave on one part of her head, but otherwise seeming uninjured. She got plenty of her favorite food that day!
GNOME Shell uses its own widget toolkit called ST. GTK+ APIs are pretty good about sebsible names, so you could grep though the source for gtk_ to see which GTK+ functionality is actually used by the shell.

Mobile internet usage worldwide blew past desktop usage in October of 2016 and hasn't slowed down since, and even that's just looking at web page views. I'd argue that holistically, smartphones have been the dominant technology platform for many years even before that, since apps are the primary interface to most services on the platform.

> We can, but it is pointless (the culture is now dead and gone)

You know what they say: those who do not learn from history are doomed to repeat it. This necessitates the moral judgments, as well.

> It also can easily lead into very messy discussion about modern day actions

All discussions about ethical philosophy end up that way. But, again, such discussions kinda need to be had for us to evolve. I understand that it's simply out of scope for, say, archaeologists, and I don't expect to find moral assessments in their work. But I also don't see why it's wrong for the rest of us to apply them in a completely different context.

Or maybe the value of colonising a planet relative to the cost just does't make it worth it by the time you have the technology to try.

Maybe every advanced civilisation ends up turning inwards to simulations rather than outwards. Maybe there are aliens all around us, but we can't notice them, because we're living in someones phone, in the latest top-hit: SimHumans5000.

There's quite literally an infinite number of possibilities where we're not alone after all, and part of the problem is that we don't just not know the values to plug into the relevant probability calculations, but we don't even know all the variables.
>But what if test and evaluation prove they are more reliable than tires filled with air?

That won't happen. Just the fact that there are so many moving parts, controlled by microcontrolelrs, all with multiple independent fail points makes the idea that these are more reliably just absurd.
The only question is, is the trade off of less reliability worth the advantage they provide.
I don't see it, but maybe there are some applications which I'm not aware of were you really really need these abilities.

> I have thought of a scheme where the first couple of years of IP are free and after that heavily progressively taxed over time ( e.g 1000 usd on third year and doubling each year after that. Once the ip holder does not pay the tax, IP becomes automatically public domain.

It's not free at the beginning, and the fees are less than you suggest, but that's mostly what we do have:

>> If we can have self-driving vehicles that are twice as safe as the average human, then they should be allowed on the streets.

Absolutely disagree with this approach. Self driving cars can't be merely slightly better than your average human - they need to be completely flawless. Just like an airplane autopilot can't be just a bit better than a human pilot, it needs to be 100% reliable.

It might be useful to have said which bit of this is most interesting.
For the first 9 years of my life, my family either did not have a PC or I was not allowed to use it for more than a few minutes. My parents relaxed a little bit and allowed my brother and i to read for an hour to play video games on the computer for an hour.

I played an online game called runescape where you could trade items to other players, but it was tedious and required a lot of repetitive typing: "buying chaos runes 80gp each".

I downloaded an auto typer but i was paranoid of getting banned. I wanted a more human auto typer so i found a tutorial for making one in visual basic. It was more or less copy and paste, and as a middle schooler i really did not understand the code.

I became really interested in botting after that, downloading, modifying, and eventually creating more sophisticated scripts. Automating the game became the new game for me.

I would come home from school to a banned account, think about how they may have detected me & automate smarter.

To this day I will often spend more time writing code to automate something than i save.

Automation is a way to make the mundane work a fun game
> And I think it's an overreaction.

I think it is too. Perhaps a better question is: should we really be using the same kind of threat models and mitigation strategies for my gaming machine where I'm alone, and another extreme: A machine running virtual machines for a cloud provider?

For the latter case, issuing microcode/OS fixes or recompiling apps to be more secure but losing 10% performance is probably a worthwhile thing. For the single user machine it's absolutely unacceptable. A gamer would much rather have the XP security model than lose 10% performance in even some rare scenarios due to (for example) extra cache flushes designed to mitigate timing attacks! I'd at least want the option.

So while I don't think that everything we held to be true about computer security is about to go out the window, I almost hope that the future will hold different security for different scenarios. Just because I run the same OS on the same CPU doesn't mean I necessarily need the same security.
I wouldn't overestimate the impact of smartphones. It's just that PCs (both in desktop and laptops) don't need upgrades anymore from year to year. You can use your PC from 2012
(Intel i5-2xxx if you remember), possible even farther back and you'd still be fine for almost all tasks. Gamers and other high-performance tasks are a niche. The biggest performance gain for these machines is a SSD, not a new PC.

The same will happen to smartphones. You can already see it. Manufacturers trying so hard to invent features nobody needs, just to have an excuse to buy a new device.
To a point, looking at the political landscape today I’d say I trust the 20 year olds over the 65 year olds. Even if you can’t get the 20 year olds to pay attention.
It is not like Intel has not repeatedly tried.

Atom is their attempt. As are more advanced MCP51 micros.

Intel's problem is that their CPUs were performance focused and as such didn't scale down as well - plus vendors didn't have to care as OSes were portable enough while software has to be rewritten anyway, so going Intel brought no compatibility advantage.
This is the same reason why Microsoft has trouble penetrating mobile market.
In NYC for example, fruits are quite expensive - watermelons, mangoes etc. You could get some veggies like cabbage for cheap, but others like cucumbers are expensive. You could get cheap chicken, yes.

So it is more nuanced than that - the generic statement of meat being expensive than veggies (or vice versa) isn't true everywhere. It would be nice if veggies are consistently cheaper than meat though - everyone wins.
Some background on RDBTools. Over time, more and more data ends up in Redis. It becomes difficult to analyze what is stored within redis, and so most projects end up increasing the memory / switch to a higher redis instance.

RDBTools tries to address that problem. It will analyze a RDB file, identify key patterns, show a breakup of memory by various dimensions including expiry, data type & encoding, key patterns and so on. It will also provide recommendations to reduce memory consumption. For example, it will tell you the right configuration for hash-max-ziplist-* and other small object settings based on your data.

RDBTools is available as a docker image. The analysis is done offline, so there is no impact to your production redis servers.
Nobody also peed on their wheels either. But they do need to handle quite a bit of dust and there is no one around to grease them. The APCs I had to use wouldn't survive that long without service.
Well it's the very essence of statistics. You probably can't predict how many of your friends will reproduce and how many offspring they will have, but you could definitely predict the average number of offspring the current population will have. Even though the "model person" with 2.1 children doesn't exist (can't exist even) it's still a thoroughly useful generalisation.

Mozilla is the same organization behind Rust. "Unsteuctured shared-memory concurrency is inherently unsafe, and also not necessary for performance; here's how some structure permits a compiler to make it safe" would be a huge ideological win for certain parts of the company.

(Also, meanwhile, none of the native platforms that Mozilla is trying to replace have disabled threads.... so by that standard, Mozilla is already miles more credible here.)

>Delivery times aren’t accurate.. {snip} A lot of listings are marked Fast&Free, but those have an estimate delivery date of Thursday.

I think that's because if they don't give a pessimistic estimate of delivery time, they open themselves up to 'it didn't arrive next day' type negative feedback and DSR scores. I'm in the UK and am selling cars part time to earn extra money at the moment - most of which need things doing (hence my markup). Nearly everything I order from eBay arrives next day (if I order before 10am), even though it usually says 2-3 days minimum. But I totally agree, it's a PITA as you should be able to filter down to those who actually will put it in the post that day if you order before (say) midday.

>- Too many Chinese sellers

Totally. They are spottable for the most part, but it's a pain to have to read the listings for the giveaways, and occasionally I'll miss it and then have to wait a couple of weeks for something to arrive. This has happened in the past when I've paid for it, and then they've said 'sorry... just checked and the UK warehouse is out of stock, so we'll send it direct from our China warehouse' - as if there's actually a UK warehouse. These have ALL been listings claiming 2-3 days' delivery.

>Too many duplicate listings.

Yup. It's getting crazily difficult for car parts which I get a lot (see above) - slightly different listing, same seller, etc. Or different seller, identical listing with slightly different price.

Exactly. Now remove the restriction that Earth #2 is active with life at the same time we are. Instead intelligent life existed 10 billion years ago. Now we've got a tiny band of space 10 billion light years away where that planet has to be located where we could have possibly detected it. It doesn't seem that unlikely that we haven't found intelligent life.
The JVM is traditionally memory-hungry. There are lines of engineering underway which will change that quite a bit (GraalVM looks particularly promising), but for now seeing a JVM process merrily consuming hundreds of Mb of RAM as the base case is not unusual.
>"Policies of an outlet can be determined by volume and slant, even op-eds"

No, op-ed pieces by there very nature are not subject to editorial review. Anyone is free to right one. And it is quite common to have editorials with opposing views published opposite each other in the Ed Op section. Saying that ed-op pieces have a "slant" is absurd. The entire purpose of an editorial is to express the views of an individual.

> Everyone knows that anything high performance kills battery

Not everyone is on a battery-powered device, and also, it's often true that "high performance" means "it completes faster and therefore spends less energy." Certainly if saying no often triggers a polyfill in actual web apps, people will quickly learn that high performance means less battery.

Agree about news pages but I wish we'd prevent them from using any serious amount of CPU, whether in wasm or JS.

> We literally have no idea what a >10^6 more advanced civ would look like.

Yep. We don't even have much of a clue about what our own civilization will look like a few hundred years from now, it seems insane to pretend we would know what a far more advanced alien civilization would look like. Imagine showing someone from a thousand years ago a picture of suburbia and them saying, "Nope, this place must be abandoned...no one is growing crops on the land, there are no wells around, deer and other wildlife are walking around houses without being hunted. Must be no humans there." Even just a few decades ago a lot of people thought we would be building cities under the seas by now (hey, maybe not everyone would do it - but with billions of humans, it would only take a few splinter groups).

It's also worth pointing out that even a civilization at our level existing at the nearest star would be undetectable to us in most circumstances (even in the extremely unlikely event that the timing matched up).

It's a argument about how close to 0 the probability of life might be, given that we know of one instance of life.

It is tempting, because we exist, to assume the probability of life arising can't be that low.

But if life is so rare that the odds of one arising in any given (causally disconnected) universe means life almost never arises, and more than one civilisation is unimaginable more rare than that again, if you imagine an infinite number of universes there will still be an infinite number of civilisations.

But being alone might be the most likely scenario if life is present, and nobody would be present in the empty universes to take them into account.

In which case our existence might easily trick us into over-estimating the odds of life arising.

Framed in a less depressing way: It might be we're not seeing the aliens because something is preventing us from observing them rather than because they don't exist.
