> If we will have cheap source of muons, we can change equation.

You can make them but the cost in energy is exactly the problem: you will be spending money on energy to make muons at a considerable loss due to the inefficient ways in which we know how to make them (proton beams, which require a huge amount of energy to create), resulting in an insignificant number of particles. If your goal is to get net energy out it would be good to keep an eye on process efficiency from the beginning. Starting off with a billion to one or so conversion loss for step one raises the bar for the subsequent steps considerably.

> Sadly, we have no such cheap source of muons, AFAIK.

Indeed we do not, and that's pretty logical.
where "my data" means a record of the shows i watch.

i'm okay with that. the shows i watch don't need to be a secret. i want advertisers to know what i watch, so more of that sort of TV gets made. If Plex can make money off this information, and give me a good service in exchange for that, it seems like an arrangement that benefits us both. what's the problem?
Sure, but building debian packages is akin to needing to read lord of the rings before doing anything. There's so many deb helpers and various files/file formats that need to be understood. How and where files should go. It's horrendously complex compared to PKGBUILD and makepkg.
Nice, thanks. I knew of arxiv vanity as well- https://www.arxiv-vanity.com/papers/1708.06733/
We have also pumped a very large amount of long-lived fluorine compounds into the air, that will last for centuries. They have from 2500x to 25000x times the "greenhouse gas warming potential", kg for kg. They are mostly refrigerants (CFCs, HFCs, and soon their successors) and transformer insulation gas (SF6). Volcanoes do emit some amount of fluorine compounds, too.

We also have a great deal of methane leakage, which is usually cited as 25-100x, and we may soon have a lot of hydrogen leakage, at >100x. Rocket launches are installing water vapor, another one, into the stratosphere like never before.

So even if we got CO2 down to a pre-industrial level, we would still have heat forcing from the fluorine- and other compounds.

Capturing CO2 is kind of pointless until we get emissions under control. I.e., a dollar spent preventing emissions buys much more than a dollar spent capturing. Solar panels and wind turbines directly displace mass emitters of CO2.
As is Uber is a vastly better product than current taxi services.
So about 3 years ago we had a bunch of on prem servers shutting down around March/April. We had even more servers that weren't shutting down so we had to "move fast" before they all had issues.

I must have spent about a week trying to learn just enough about prometheus and grafana (I had used grafana before with influx but for a different purpose) so that we could monitor temperature, memory, cpu, and disk (the bare minimum).

The goal was to have a single dashboard showing these critical metrics for all servers (< 100), and be able to receive email or sms alerts when things turned red.

No luck. After a week I had nothing to show for.

So I turned to Netdata. A one liner on each server and we had super sexy and fast dashboard for each server. No birds eye view, but fine. I then spent maybe 3-4 days trying to figure out how to get alerting to work (just email, but fine) and get temperature readings (or something like that).

No luck. By the end of week 2 I still had nothing, but a bunch of servers shutting down during peak hours.

Week 3 I said fuck it I'll do the stupidest thing and write my own stack. A bunch of shell scripts, deployed via ansible, capturing any metric I could think of, managed by systemd, posting to a $5/month server running a single nodejs service that would do in memory (only) averages, medians etc, and trigger alerts (email, sms, Slack maybe soon) when things get yellow or red.

By week 4 we had monitoring for all servers and for any metric we really needed.

Super cheap, super stable and absolutely no maintenance required. Sure, we probably can't monitor hundreds of servers or thousands of metrics, but we don't need to.

I really wanted to use something else, but I just couldn't :(
It's different. Nowadays, central banks create money out of nothing. Companies can create these loyalty points but they need to pay the customer back with services when they come back to exchange it.

Like the other reply said, there is no natural equilibrium.

We want to return to pre-industrial levels because we’re used to it and we liked it more then.
The next time I try and do a serverless site I'm going to use SST. The last time I tried making one, I got all the way to the end of the project using Pulumi only to realise that I couldn't do any tests of the severless functions locally which would have made things an absolute nightmare. I think the only way you can do this is using AWS SDK or SST. Something to be aware of for anyone wanting to go down this route.

“Natural concentration” is not the right way to look at it because there are higher concentrations that predate the industrial revolution and humans. The all time high (that we know of) is from about 350,000 years ago. This was by all means natural and pre industrial revolution.
Cabs and car services were (and still are if we ignore Uber and Lyft) effectively non-existent in many small to medium sized towns. And where they existed, they were exorbitantly priced. Where I lived (while Uber and Lyft were becoming popular) the local taxi service had around a dozen cars for a community of around 250k people. The only other transportation services were catering to the elderly and infirmed and pretty much just drove to hospitals and clinics.

Uber and Lyft introduced an option there (and in many similar towns and cities) that did not, or effectively did not, exist at the time.
Thanks a ton for the advice!

The organisation is like a complex organism, and engineering is merely piece of the whole. Each piece contributes to and depends on each other (roughly) to make a business function. Therefore, the word "engineering productivity" by necessity should be put under the category of "intangibles" (in most cases).

Still, we can consider some interesting thought experiments. Say, you start with a purely technical team; there are no marketers, no HR, no managers, etc, and the team gets a product going in the market. In such a limited case, one can characterise productivity with "revenue per engineer" (essentially - total revenue / number of engineers).

However, in reality, if the marketers, the HR, and various managers, leaders and salesman don't do their jobs, despite having a great product, revenue will approximate towards zero overtime. In reverse, if the marketers merely do their job perfectly, but there are no engineers delivering the product, again there won't be any profits.

Despite all these caveats, let me share why I think "revenue per employee" seems like the most useful metric here. Consider the "average revenue per employee" for these two companies:

ADP: $284,453

Apple: $2,560,571

Google: $2,020,329

Apple/Google are 10x ADP. I'd argue a good part of this 10x difference we see in the output primarily due to the differences in engineering sophistication. The engineers in these more profitable orgs are doing qualitatively different "types" of engineering (hardware? prototyping? deep research? higher standards?). Increasing engineering prowess, trying more sophisticated projects seems like the biggest boost to the bottom line.

401k and IRA were created in a system that included pensions. Now without them, we have a huge shift towards a volatile market with a lot less guarantees, and lower limits. This isn’t a good system we have. Most are ill prepared.
The emails and slack messages are indeed authentic. None of the participants involved have ever denied it probably because doing so under oath would put them in legal risk. But luckily for the participants their misconduct has been largely ignored outside of right wing outlets, despite the fact the lead authors joking about how to mislead the press NYT specifically.
If you're referring to MCAS in 737, the software itself wasn't the main problem; I'd say that the main problem was that it wasn't even a documented feature (let alone the engineering of the system itself).

The pilot couldn't even turn MCAS off originally. That's not a software thing, that's a "who the F designed this" thing.

My fiancee has a handmade women's and children's cloth business here in Germany where I help out with IT, software, customer support and back office. We are affected by this as Etsy is currently holding about 4000 of our Euros. I am glad we are not totally dependent on Etsy (and on this business) because otherwise it might well wreck us financially.

I would say that our account is a good citizen. We have been on Etsy for two years fullfilling over 1200 orders and garnering a 5 star ratings from hundreds of reviews. In all the time we operated we had a single, unjustified case against us that was quickly withdrawn by the counterparty. Not a single Etsy order was lost during shipping, and we have managed to maintain a positive account balance without any issues related to fees or refunds. Our return rate is also below the industry average for our niche.

Now, we are not perfect. Often we run over the promised delivery date by a few days simply because we get swamped with orders. We also don't ship single items with tracking. Rather we send it as a German Post "Big Letter" which is quite reliable and has the benefit that people can receive it in their mailboxes and don't have to sign for it. This works quite well and is "the way" that we handmade / second hand people usually send around stuff.

This lack of tracking is, I think, the crux of this whole matter. Etsy really wants sellers to add tracking and it states in the "reserve" that you can get your money at once if you just add valid tracking.

To me this leaves a bad taste. I really resent being "nudged" by platforms like this especially if there isn't even a problem. The fact that they can simply change the rules out from under you is also disconcerting. The first time we noticed that this was even happening was when they already had withheld 2000€ (1). The worst thing about it is that we raised a support request for this, for which you have to jump through really stupid hoops, and have not even heard back from them in weeks. Not even a boilerplate response. This is really a scary prospect, to have your income be at the mercy of literally a faceless entity that'll happily take your fees but CBA to connect you with a real person when you run into trouble.

I also want to mention that I think a "reserve" is generally reasonable. But it's not really reasonable to hold 75% over 45 days. I think if it was 25% for 15 days from shipping then, generally, seller would be able to handle it financially.

(1) I am necessarily not blaming Etsy here, we are all just very busy and I just expect for this stuff to keep working like it did.
That is the point where we started adding greenhouse gases that lock in energy from the sun, we need to at least get back to those levels to start releasing some of the heat. Otherwise we're containing to add insulation to an oven that already overheating - you'd ideally want to take off all the insulation and the metal casing since you can't turn off the heat, but the casing isn't an option so we need to remove the insulation and hope it hasn't gotten too bad yet
I have a remarkable 2 and use it to read PDF and e-books. e-pub was slow, so I use PDF.

It doesn't have to phone home or use the cloud, which is sort of refreshing. I have never hooked it into any network or even bothered updating the software.

I use USB which becomes a network interface, then connect to http://10.11.99.1/ and drag/drop files. This is all local.

No built-in lighting, but it works great with a reading lamp or in sunlight.

It replaces a book in my lap and is just for reading books. Sometimes I use it while exercising on treadmill, and with the big screen and large type it works great.

only nit, is sometimes swipe when turning pages is ignored and I have to do it a couple of times. (Maybe it is sleeping and needs to be woken?)
I almost always just VPN through home, even on my phone (gets to use my pihole that way). It definitely depends from place to place though... sometimes using the VPN is dramatically slower than it should be. At least my uplink at home is now 100mbps from the 20mbps it was when I signed up, which helps a lot.
A pension would be a form of that.
The post-AI way to engage with the podcast ecosystem. The AI listens to every episode the comes out, finds the best coherent segments for every user (based on their textual self description, and soon Twitter graph as well).

It sends these segments to any podcast app via a personalized RSS feed.

The podcast episodes become the source material for a newsfeed of personalized segments. Means you can get value of pod episodes without having to listen to the full thing.

Segments also jump to the point, skipping long intros, ads & chit-chat which we somehow tolerate in pods (but you'd never watch a YouTube video that took 15 mins to start).

The SEC is just the wrong organization to be enforcing laws in crypto. This was a scam that was done out in the open and launched 4 years ago. People conned into buying this have already lost their money and they're not getting it back. The founder will use some of the $1B+ he's made of it to defend himself in a long, drawn out court case that the SEC will eventually settle.

The SEC's purpose is supposed to be to protect investors and no one is being protected by this.

Can you list some of the thousands of reasons?
There's still some repairable stuff in most refrigerators.

I have a GE side-by-side refrigerator that's probably 10 years old. It still works, at least as a refrigerator/freezer. The icemaker and water dispenser never worked well and don't work at all now, and at one point started leaking which ruined the laminate floor in the hallway behind the kitchen before it was noticed.

I have replaced the control circuit board, and the freezer defrost heating element. These parts are available and pretty easy to install if you are even slightly skilled as a home handyman, and in the time I've owned it, the need for these repairs doesn't seem unreasonable. The board likely got fried due to a power surge in a thunderstorm, a reminder that most modern appliances should get power through a surge supressor. The defrost heater failure is typical of any frost-free freezer.

I think putting water and icemaker in the freezer is a mistake and won't buy another one like that. If you need more ice than you can make with ice trays, get a standalone ice maker.

Yeah matrices are more abstract. I guess I am just pointing out that your concrete example of non-commutative rings (matrices of matrices) still needs a proof to demonstrate bijection between 4N x 4N (scalar) and 4 x 4 (N x N(scalar)).

Block MM demonstrates the equivalence.

Dynamical systems can have equilibrium points —- e.g. an inverted pendulum is stable when hanging straight down. If you deviate too far from an equilibrium point, the system may find another equilibrium that is less desirable for the user. I’m not an expert in climate change, but those things certainly happen for engines, robots, and other systems.

The FediVerse doesn't work that way. There is no "the" mods.

The people posting this stuff won't be posting to the BBC. They will be posting to far away places each with their own moderators. They'll either get suppressed at the source, by those moderators, as complaints come in (which they will probably do quite rapidly); or it will get around that those far away places don't moderate, and the far away places will get silenced and blocked and make it onto the aforementioned lists, meaning that the (civilized) world won't pull any posts from them.

The reporting system, bear in mind, reports to the origin server, which won't be the BBC. If I, for example, see an unacceptable post in reply to something posted by the BBC, my report doesn't get seen by anyone at the BBC. It gets seen by my local sysop and the sysop of the origin node.

> There were places that were great ideas for planting — west sides of pathways to help block the blazing afternoon Phoenix sun.

It's interesting that you miss the forest for the trees here.

There really are no trees that are "great" for where you live, because without human intervention like what you described, there really are no trees that sustain themselves in the Lower Sonoran area. It is essentially a desert.

So the long term solution is really just slowly depopulating the Phoenix area or having landscapes that are appropriate for a desert, and planting trees where water isn't so scarce as to be unsustainable without human babysitting.

> And yet, there places they planted too close to existing trees, where they won’t even get sun (plants compete for sunlight, not root space)

Competing for sun isn't really a thing in a desert, because canopies in that landscape are a liability rather than an advantage. They contribute to water loss, which is extremely scarce.

If anything, having partial shade is good protection for young trees, which are more susceptible to variations in drought and heat.

Kindly, how can you seriously be calling this secure?

By your pictures this is /e/OS, a system which hasn't had the browser/WebView updated in 7+ months, is consistently 2 months behind the ASB, is 1 year behind the PSB, and has a PDF viewer with an engine from January 2016.

That is 196 known security issues in the browser, hundreds in the OS, and another 60 in the PDF viewer.

I document these issues and many more here: https://divestos.org/misc/e.txt

If this really is /e/, you seriously need to address this.

Go rebase on an actual production OS like GrapheneOS, my DivestOS, or CalyxOS.
