> Drain-water heat recovery technology works well with all types of water heaters, especially with demand and solar water heaters. Drain-water heat exchangers can recover heat from the hot water used in showers, bathtubs, sinks, dishwashers, and clothes washers. They generally have the ability to store recovered heat for later use. You'll need a unit with storage capacity for use with a dishwasher or clothes washer. Without storage capacity, you'll only have useful energy during the simultaneous flow of cold water and heated drain water, like showering.

> ...

> Purchase prices for drain-water heat recovery systems range from $300 to $500. You'll need a qualified plumbing and heating contractor to install the system. Installation will usually be less expensive in new home construction. Paybacks range from 2.5 to 7 years, depending on how often the system is used, and the temperature of the incoming water, which is dependent on ground temperatures.
Yeah, that's how the creators fund themselves.

(I'd prefer if YT would prevent creators for advertising in Premium videos, but I bet that would not be accepted happily either.)
DMSO is terrifying, dude, it makes skin so permeable as I understand that supposedly even live bacteria outside of the skin can be transferred inside the skin.

It's something I'm shocked seeing people casually use, similar to piperine.

Like, with piperine, you're maximizing "absorption" by directly blocking/inhibiting the p glycoprotein pumps that pump toxic substances back into your intestine, etc. Wtf kind of short sighted thinking is that! Why is that remotely considered reasonable long term. It makes things more "absorbed" across the board.

Neither is a good tool to play with, usually there is a decent, much much safer "hard way" for most of these methods in my experience, at least. :3 :)
Of course they can't collect ”commission” on payments they're not involved with. The entire point of the Act is to crack down on anticompetitive behaviour. Your example is textbook, and I am certain the text of the law bans it.
The builders of my house (who were angling for, and got, PassivHaus+ certification for it), built a heat exchange for the drains on the second floor that warms the intake to the hot water heater. It works, but it's pretty limited, in practice it does pass some of the heat from a bath or shower or dishwasher run back, so that's something. Of course the timing matters, water drains pretty quickly, even from a bath, the there's no coordination to guarantee the water heater runs while that happens (other than the good chance that if we just pulled hot water out it will be running to replace it, but sometimes that isn't immediate).
It's not blasphemy per se. Wholegrain rice is popular for health reasons, and convenience stores carry wholegrain onigiri sometimes
Clothes detergents have been able to effectively clean in cold water for decades. The only reason people still wash using these detergents in hot water is ignorance. It's such a huge waste. Please stopping washing clothes with brand name detergents using hot or warm water. It costs more money, does more environmental damage, and doesn't even make your clothes marginally cleaner.
I saw this mini-computer recently, the UM790 Pro, and I almost bought one as well. The AMD Ryzen CPU, AMD Ryzen 9 7940HS CPU, has a rating of ~30,000 on the CPU Benchmarks page (https://www.cpubenchmark.net/high_end_cpus.html) which is quite high end for the size/cost.

The only caveat is that I am running a 10Gbit ethernet network at home and it wasn't that costly to setup. A 10GigE switch costs around $500 CAD right now and that is all you need.
I forgot to mention in my previous comment that I saw no sign up box for the newsletter.

> I believe the hardest part of using spaced repetition to learn programming is creating good decks, it's a ton of work.

Agreed. To have always been disappointed with the programming decks I have created.

> About open sourcing the web app, I might do it. It's a Django app, and I've published some videos while coding it

I saw the videos, thanks. I think a generic platform would have value, even if there was a paid option with more features (payments etc.)
> Why is everyone in such a rush?

Because we live under an economic system that says you must produce value for capital or die.

This is all very good advice. AND, I think we would have many fewer bad programmers and many more good ones if fewer Knuths were spending eight to ten hours a day mopping floors at fast food restaurants for $7.25 an hour, or writing garbage JavaScript for fly-by-night startups for $65,000 a year.
I thought about the exact same thing, inspired by my admittedly too long showers. Although I pondered whether too cold sewage could lead to more blockages.
> That just my view of the aesthetics…

As wind turbines aren't a very rare sight, I think it's reasonable to assume that most have already seen a wind farm in person. Newer generations in Germany also only flash when planes are nearby.

> Nobody ever bothers to talk about what will be done with these football field sized blades (I’m guessing at least 100k of them by now?) when they’re decommissioned?

At least I've seen a lot of talk about it, most of it ending in "we're trying to reuse them for something else with mixed success" or "recycling is possible, but not yet done on a large scale, but we hope it'll increase".

> do you think any of the companies who signed these 30 year leases will be around to de-com the turbines when they start falling apart? (Answer is no)

At least in Germany, where wind turbines from 20+ years ago are being replaced by newer ones (due to the much higher power output), this hasn't been an issue yet. In contrast to oil and gas sites, after the wind turbine has seen it's EOL the land isn't worthless for the purpose, but a new wind turbine can be installed. Thus for most sites this isn't much of an issue. This isn't to say that regulation is a bad idea (and I'm wondering why leases were signed without a clause to obligate the operates to remove them), but I don't see the fundamental point of conflict, since the land isn't worthless afterwards for energy purposes.

> Then there’s the never ending problem of freezing…

At least your first two sources suggest that electric heating works (but unfortunately not if it's doable from the energy generated by the wind turbine itself, but I assume that to be the case, otherwise it doesn't make any sense), and the third suggests a fault of the power connection of the initial fault (and quite a bit of tabloid rambling that I didn't read, I have to admit).

PaaS for AWS(eks)
I recently launched my open-source product, visualith.com .
It is a PAAS for AWS.
- It helps you quickly deploy cluster(EKS) and applications using GitOps principle (ArgoCD).
- It contains graphana and prometheus pre configured.
- It also contains Kubecost preconfigured.
I am unable to get a single user to try the product. What am i doing wrong or is the timing wrong.
Desperately need some suggestions.
I've fought these arcane issues before. I don't have a ton of experience in audio, but I've seen them at lower frequencies (in servo amplifiers, where rectified RF causes DC offsets) and higher frequencies (as intermodulation in RF amplifiers from strong out-of-band interfering signals).

This is why you find things like this in design manuals. These are focused on offset errors in instrumentation amplifiers hooked to long cables (but intermodulation is an equal or larger concern in applications that care about frequencies above DC):

"In addition to filtering the input and power pins, amplifier outputs also need to be protected from
EMI/RFI, especially if they must drive long lengths of cable, which act as antennas. RF signals
received on an output line can couple back into the amplifier input where it is rectified, and
appears again on the output as an offset shift."

https://www.analog.com/media/en/training-seminars/tutorials/...

Microchip says the same thing: "Amplifier outputs also need to be protected from
EMI/RFI, especially if they must drive long lengths of
cable, which act as antennas. RF signals received on
an output line couple back into the amplifier input
where they are rectified and appear again on the output
as an offset shift."

Note that I'm not really saying you need anything special on speaker cables, other than common sense: don't separate the pair for as much of the run as possible, and make sure the terminations at the end are not total garbage. If you have strong RF sources nearby, like when I had a 50W HF transmitter in my apartment, you may need to add RF chokes/ferrites on the amplifier end of speaker cables to reduce interference (I did).

Indeed, the ARRL (American Radio Relay League, an amateur radio association) describes that adjusting speaker cables is a frequent way to cure interference for neighbors of people with high power transmitters:

"Speaker wires are often 8 to 16 feet long. When you put two of them together, you make an efficient receiving antenna. Try bundling the speaker wires to reduce their effectiveness as an antenna. This procedure has been known to eliminate the interference all by itself."

"A: For a detailed explanation, you can refer to the ARRL Handbook's section on controlling RFI, and the section of the ARRL web site on EMI/RFI Products and Other Resources. You can build two of them, one for each speaker output. Wrap ten to fifteen turns of speaker wire onto an FT-140-43 ferrite core. Use an FT-240-43 if the speaker wires are large, and use "73" material for interference from 80 or 160-meter signals. Alternately, type "31" material is an excellent general purpose choice for HF. Install them right at the amplifier. If the system uses amplified speakers, you should install one at each speaker, too."

Yes, it will require a plant on the surface of the Moon, but the technological chain is rather short, so maybe it could be somewhat limited in mass.

You'll need energy, which could be collected with solar panels, the system, like bulldozers and excavators, for gathering regolith, pulverizing rocks, the reactor, the collector for volatiles, the oxygen separator and oxygen liquifier. Next you'll probably need containers for oxygen, maybe electromagnetic mass driver to accelerate those containers to about 2.4 km/s, which will also need some energy.

All these components are rather well known technologically and discussed for long time; I don't remember a forbidding level of energy being mentioned.
On actual network gear you'd typically drop the interfaces into a subnet/broadcast domain, but the blogger here has put everything in /32s and it looks like it's creating a peer connection without a shared domain.

Any particular advantage/disadvantage to doing it this way?
Good for you, and the spirit of open software.
Yup, doesn't make any sense at all.
USB4/thunderbolt is a magical protocol. Turns out the fastest way to move data between 2 modern PCs is to connect their thunderbolt ports with a USB-C cable. The connection shows up as a ethernet port on Windows and I can easily saturate a SSD with its 1GB/s+ transfer rate. And it just works (tm). Reminds me of firewire on these 20 yo Macs.

And What happen if you wire both ports together on the same PC?.. Do you get a broadcast (thunder) storm?
No burn that I could notice in 2 months of use now. I don't think that's a major problem for laptops tbh. I don't use fingerprint sensors on laptops and ordered mine without on but AFAIK it does work on linux if I recall correctly.
Yeah, I think the website the author linked to has old data. It's 3x that in California.

Does EU have an alternative to android and iOS? Is Symbian a thing still or have they given up?

Used VS since 2001. Then started developing on Linux and Mac, which I prefer. But here you don't need the full VS installation, only the build tools and Windows 10 SDK, and apparently it can be installed by a script. It's a non issue. Otherwise use WSL then you won't need VS https://crystal-lang.org/install/on_wsl/
Since you asked, based solely on your earlier comment, I would suggest being more open, humble, and respectful. I recognize the downsides of relying on frameworks, but I can also see good reasons for using them. I wouldn't refer to colleagues using frameworks the way you did.

Dandelion Energy already uses sonic drilling for heat pumps:
https://dandelionenergy.com/installing-geothermal-through-be...
Dandelion Energy is a Google X spinoff.

Quote "Dandelion developed an innovative and proprietary sonic drill suite that’s lighter, cleaner, and can install 14x faster than a conventional well drill."

The thesis in the article goes against some conventional wisdom, but some engineers validated the potential of that approach.

The state of art you mention would already make it quite expensive (e.g. mud causes mess, making it less appealing for retrofits, and two trucks add costs).
At that rate how are there any data centers in California?

Ok, but I’m not sure what that has to do with what I posted.
The intellectual value of an MIT degree is only partially the classes themselves — it’s the whole experience, including who you meet, how you learn to think and the stuff you do.

It’s hard for me to appreciate the value of the MIT brand as a graduate. This feels like a small dilution of that brand, but so what?

I wonder what the Institute’s objective is. Education is such a minescule part of what MIT does that perhaps it’s just an experiment in democratization of the MIT curriculum that someone wanted to try, and nobody else cared enough to say no?
Australia. It's expensive, career wise it's very limiting and the health care system is bad if you have children.

Dynomight suggested [1] recovering the heat from hot showers by showering with the drain stopped and letting the water cool to room temperature before draining it.

I remember thinking it was interesting at the time, but I have not tried it (my shower has a low lip so it couldn’t hold very much water).

I have experience with both, but will always opt for Svelte if I had the choice. In practice your employer will likely make you use React anyway if you code professionaly

I'm not anything special. There are tons of people who are curing their crohns almost accidentally via other paths who just so happen to stumble into the cure because they threw a wide net.

It'snot like I'm the only person ever to have considered it neither. Easy to find after you realize, so it's certainly well within the 'many many others curing themselves'. But you look at crohns forum and it's almost as if medication, surgery, and diet are the only options? Like what? Not even the wiki page is that limited.

>Some people are offended that chronic disease patients with some intelligence can know their disease better than specialist doctors though. I never understood this reaction, I guess it's just some kind of gatekeeping that every profession has...

That makes sense to me.

For me, I just went and read every single science article available. I also have a great option to experiment on myself. Do something silly for a week or month and see how it works out. Journal and track how it goes.

I figure I'm sort of half way alleging a conspiracy, but I really don't think so, there is no Illuminati who want crohns disease to get worse.

I must say, my poos are so much better after lol.

I'm also trans and I find the same thing, the communities are super hostile to anything which might end it because they get their identity from it. Not that I'm saying there's a cure to being trans/autistic. That happens pre-natal exposure.

Maybe there needs first to be an investigation on what kind of process failure existed for those things even to happen in the first place?

If both failed at their jobs there's something a bit more smelly than just "individual responsibility" going on in an industry where process is extremely important for safety, don't you agree?
Ahh the grand BigCo tradition of acquiring a company and then setting fire to it.
I think the answer is unique to your situation. I've seen and read many experiences of those who have both used React and Vue (including myself), and many prefer Vue. That said, because React is more popular, this is going to get your foot in the door in many more companies, and it's a bit of a "well everyone is using React so we will too" type of spiral.

For me, if I were trying to get hired, I would choose React. If I were looking for my own side project or in a position where I got to choose, I would choose Vue.
I'd learn both, or at least start to, and find the one you like best.

I don't get the point of learning something you don't enjoy working with.

a) This is explicitly forbidden

b) Apple is free to act as payment provider, but can't force businesses to use it.

If they decide to do it anyway:

In case a gatekeeper does not comply with the obligations laid out in the DMA, the Commission can impose fines up to 10% of the company's total worldwide turnover, which can go up to 20% in case of repeated infringement. In case of systematic infringements, the Commission is also empowered to adopt additional remedies such as obliging a gatekeeper to sell a business or parts of it, or banning the gatekeeper from acquiring additional services related to the systemic non-compliance.

Symbian's last release was over a decade ago. You may be thinking of Sailfish, which is still coming along, but... not a contender anytime soon.
Love a published null result!
I hadn't really thought about it much, but googling it looks like there's a discount programme for a committed spend of around $1M/year. For a small company, that's a lot of money, and it was an unusually large amount of bandwidth for the size of company. I suppose it makes sense now I know they're interested in companies spending that sort of money.
I'm kind of wondering the same thing learning my guitar: Maybe a good thing is to approach an issue with different ways your head has to think about it.

Like, yes. I can just spaced repetition the heck out of the notes on the fretboard. Just hammer my head into the notes on a string until I pretty much just give up. Always an idea.

But I've found it more effective to mix contexts up. Some weeks, I just drill notes because I'm lazy. But then I also start tinkering around for a week with some weird scale, like hungarian scales and such. Some other week, I'm tinkering around with arpeggio chords, some other week with cord progressions with power chords, some weeks I'm trying to replicate some sound or feeling of a song.

And over time, the brain is putting things together. Suddenly there are realizations: Hey, this is just a G-Minor scale, which makes sense for a somewhat solemn song. Oh, this is just a G-Major scale but we skip those. Wait, I remeber half the notes of the scale, isn't this just that pattern? Also, if the scale is like this, couldn't we try playing that?

It's just a weird feeling, because the amount of things I think I know expands at a much lower rate of the things I realize I don't know - or don't have the technique for, lol.

But I'm kind of considering using a spaced repetition algorithm to just poke for 5 to 10 minute guitar things to do to get both the muscle memory and the neural connections about them going.
I have been using eOS for years without any of the Simple Mobile apps. I have checked them out on occasion and I wouldn't call them "bad" but I have always been able to find more capable open source apps that fit my needs better.

It really depends for whom you are doing the coding. If you're a corporate contractor or wish to work as a developer in the corporate world you will have an easier time learning React because as you stated it is far more common.

If you're building a startup go with Vue if it allows you to get up and running faster. Use React if it gives your project a distinct advantage because of a library you can access that gives you a specific advantage over your competition and gets you to market quicker.

For the record I am a Vue/Nuxt developer but in my case its because I am a solo entrepreneur and I find it easier to just get stuff done.
Yes! The Phone app seems to have been released today. I am just an ordinary user, no affiliation with the project. I used pretty much all the SMT apps, so now I am slowly migrating to these new alternatives as they come out. I just hope that the project is based on better foundation and on a community, rather than an individual.
Vue 3 follows a similar approach to Vue 2 (reactivity on objects, translates automatically to DOM updates). Although there have been some syntactic changes (such as the composition API).

Job-wise React is probably the better option, in terms of number of job offers you might get.

Vue’s smaller ecosystem has not proven to be difficult in practice. I think we could benefit form importing less dependencies in our projects anyway :)

React seems hard to use, ever-changing and generally not a good option on a technical level. I haven’t used it professionally but that’s the impression it’s given me
