In practice the lineman risk isn't as real as it seems at first. Odds are when the lineman shutdowns a segment, if your system tries to supply power there are enough other people on the segment that you will trip your local overload protection and isolate the grid.

I don't blame lineman for not wanting to trust that though. My understanding is their practice is to always short out the line when working on them as that is the only way to be 100% sure it isn't live. (note that linemen work on live lines all the time, but when they need a dead line they ensure it is dead)
I have some marbles and a crucifix ( that kind you hang on a wall) made of this material. I inherited them from my grandmother , the marbles was intended to be toys. The crucifix also is visible in the dark and it's the object with major emissions, but nothing dramatic. The marbles emit mostly alpha rays. Both can excite notably my Geiger counter, but, storing them in a metallic box, (i.e. that sheet metal box for biscuits ), no emission leaks. I'm using the marble in my DIY random number generator, based on a Geiger tube and an Arduino board.
Well, until you get into conflict minerals, depletion of natural resources, environmental pollution, exploitation of workers, ...

You don't need to convince your wife to switch, you can start by helping her setup the app on her phone and tell her to use this app when talking to you.

Lower the stakes and the expectations. Even if she is starting conversations with you on any other app, you can still start the conversations on Element. There will be bugs and quirks she will find, you just offer help and ask her for patience.

With time, they get used to the app and will be okay with starting the conversation with you there.

That's what I did with my wife, my parents, closer family and friends. Then you get one day like the recent Facebook outage, and they will come to you to ask if you can help their friends to sign up to it.

Slow and steady is the way I found to run this race. I already managed to get rid of WhatsApp and Messenger on my phone, it's only telegram for the odd group chat that is still resisting a full change.

No, not on its own.

What I've seen done for this sort of application is to stack the RPi on top of, say, an Arduino Mega or SAMD51 in team. The Pi handles database, network (NTP, HTML interface, update work) and the micro is sort of a real-time port expander.

Think of an access control scenario ( doors not ports ) where you have n doors ( potentially 2n readers, either wiegand or directly RS485 ) you then have 2n contact closure sensors ( door position and request-to-exit ) and an output relay to control the lock hardware power. The real-time needs of this type of thing scale to super-wide while the database lookup scales separately.

You keep a fraction of the user table on the micro controller, based on frequent use of the doors attached directly. Hang another micro controller when you've used up your I/O but connect it to RS485 doing the "same thing" with different labels/IDs. But the Pi just keeps the full list, the full log if wanted, and gives a target for your user update work and adding new doors.

I think what people like about the Pi is the modularity and ecosystem. I can get a hat for relays and sensors and things (and a super-duper hat thing for door control if you dig deep enough)

You have to engineer all of the reliability ( RTC, watch-dog timers, power state control, opto-isolation of inputs, debouncing of buttons, on and on...) but if you have more time than money, you can learn a fair deal about a particular field by building something rather than buying it.

Then when you finally have horsepower at your disposal, you may actually appreciate the value of the readily-available devices built to perform such duties reliably.
I then wonder if somebody has a bumpbot now, just to prevent these issues from being closed by stalebot. :)
This is made explicitly illegal in many places. I've looked into this when I was still heavily in renewables and depending on where you are crossing your lot lines with power supplied to another lot that doesn't have a grid hook-up can be a problem. Of course, when the power goes out everybody does this anyway (from generator or off-grid installation to the neighbors freezer, for instance). But for a permanent hook-up I have not seen it.
This sounds very similar to what we’re doing and we are in the process of migrating most of the EAV models (other than the relationships) to a json1 column (Which I’d argue is still EAV just in document format). Keeping the relationship foreign keys outside of the json allows the database itself to enforce referential integrity.

The difficulty with having all attributes be EAV becomes apparent when having to do multiple joins to fetch a single record type (what would be a “table” traditionally). Although this is manageable, the bigger difficulty I’ve found is synchronizing deletions of records, especially if deletions/insertions are done in bulk. Rather than just 1 transaction you have to do multiple delete/insert queries to also delete/insert the attributes and the values and they should be done in a way that doesn’t break key constraints.
I would imagine using a CRDT would be appropriate for the data you want to sync would let you sync state between multiple open clients.
Resistive heaters are only highly efficient if you draw the boundaries of your system very tightly. If you take into account the losses during generation, it's a terrible picture. It's far, far more efficient to burn the fuel directly to generate heat than it is to burn the fuel to generate electricity to generate heat. The grid is perhaps 40% efficient at converting fuel to electricity.

It's harder to be so absolute when talking about resistive heat and renewable energy, but it's almost certainly a very poor use of your electricity. You could either drive a heat pump (and get 4x the heat per dollar of renewable investment) or you could spend far less money to build a solar hot water system (or, if you have the renewable forestry, a wood burner). Resistive heat really only makes sense if you have excess renewable energy and literally nothing else you could use it for.
Fairphone?
But a heat pump is more than 100% efficient.

I have both a well and septic, so I totally get it. But if you are connected to public water or public sewer, which often a municipal monopoly for good reasons, and you have limited other choices, the local government places restrictions on the cost of getting hooked up to public water and sewer if there are no alternatives.

In any case, water and sewer are indeed considered necessities and you are unable to sell or convey a house in the state that I live without a functional water or sewage system, whether on public water/sewer or on well / septic. If you have a non-functioning well or non-functioning septic (outhouses are no longer allowed), then you can't sell your house, and also you are in risk of having your own house condemned. So these are indeed necessities.

I'm not here to support worldcoin because I think it's a bad idea. However, proof-of-work is also a bad idea. What bitcoin is is a decentralized clock rewarding random machines every tick. It produces bad dynamics. Parento distribution of reward, huge amount of energy waste. All so rich people (Yes, most bitcoin is held by a few rich people) can transfer wealth.

It's a stupid idea. You can appreciate it's simplicity and how everything fits together like puzzle pieces, but it is ultimately a stupid idea because it lives in the real world and has predictable real world consequences.

Agreed. But given what I've seen in some off-grid installations I really don't blame them. And I have seen one installation that tried to supply all of Ontario when it didn't go off-line as it should have, that wasn't a really pretty sight. The inverter died quite spectacularly, judging by the scorch marks on the wall above it, all of the magic smoke had definitely gone out of that one.

The Facebook Ad buyer Facebook groups (meta, I know) have been in panic for the past few weeks as a lot of people report their previous targeting settings are no longer producing results. Some or unaffected or doing better, but there is definitely a quality fallout for advertisers and that can lower sales of facebook ads quickly.
To me, it rather feels like the opposite, like the "wanting to get better" explanation is a moralistic, post-hoc rationalization. I live a reasonably successful life, but many of the things that made it so are just luck. I was born in a reasonably affluent country, and my parents always provided good care and abundant financial support. I am pretty awkward, but smart enough to get through life. I am naturally interested in programming computers so I don't even need to make an effort to do it, and this happens to match one of the most demanded jobs. I am depressed/anxious but thankfully SSRIs work very well for me. I had no bad influences regarding drugs. To me, it seems those reasons have had a greater influence than "wanting to get better" could ever have. In fact, when you're depressed, there's not even a "wanting to get better" to be had - you're just reflexively pulled to bad feelings.

People will still buy all sorts of computers. Lots of options will appeal to different people. Intel is finally being forced to actually complete. It's all good. My M1 Mac (not even M1 Pro/Max) is quite easily the best computer I've ever owned, but I have zero need to proselytize and simply do not care what you or anyone else use.

That doesn't change the fact that the above claim about "laptop Xeon chips" beating the pants off the M1 Max is delusional nonsense.

I have to comment on the RTX 3080 bit: I have used many PC laptops over my career, and currently have a Lenova with a fat, barnburner Nvidia dGPU. The GPU is literally never used, because the moment it engages my battery life falls to cartoonish levels (somewhere in the range of 40 minutes), the laptop becomes a space heater, and the fans turn into jet engines. This is the sort of "spec chasing" that the industry is addicted to, providing absurd, completely unreasonable solutions just so someone can boast. One of the things about Apple, quite contrary to your claim, is that they don't do that. When they provide something, it is meaningfully usable and useful 100% of the time.
>The optics are absolutely terrible on these issues. If I can speak for some of the folks in the rest of the world, we're laughing and shaking our heads.

(I'm ofc talking about the insanely obvious cases. Court is fine for more complex cases.)

After the phone call we should just see punishments large enough to encourage people not to repeat the mistake. Since worker rights are more like really expensive jokes right now it seems reasonable to do some package like 1) a big fine for the company, 2) a good few years of salary for the person reporting it, 3) require that the employee responsible for the violation is also fined personally if not fired. The compensation can be conditional [say] if the employee quits or is fired over the next 10 years. (after 9 years 10%)

Its really not as complicated as it sounds. For really big violations the mechanisms are usually all there. If you have slaves do forced labor we don't require the slaves to take you to court then merely instruct you to pay the missing wages.

We could even require employees to report it. Then the reference call is less of an issue.

I meant retrieve actual physical fingerprints that are on the phone, not digital scans of fingerprints.

So if you use fingerprints to unlock your phone, and a dedicated attacker steals your phone, they could create fake finger prints from the prints you left on the phone (as surely you do touch your phone), and use them to unlock your phone.

I stand corrected:

a) Bezos is not CEO since July, he's Executive Chairman

b) he only owns 11%, yet he's the richest (or second richest) man on earth

I don't know if I would call this "pretty far from total control". Maybe it's far from "total control of planet earth", but he's certainly playing in that range.

Point is: you don't have a say in what Amazon does, period. Not even a vote, however insignificant that might be.
Just saying, at this stage, if I were Facebook and I wanted to take the pressure off, I’d be putting out little stories that make the story about the whistleblower instead of about Facebook. I’d also focus on stories that will make us disagree with her over various particulars rather than with Facebook.

Facebook has a pretty simple problem: they pissed off too many people, either by taking too much of the winnings for themselves or by inserting themselves into divisive governing tasks or just by ruining what earlier users liked about the product. Lately I even think the anger towards them is because they represent the Internet, and the whole Internet seems to suck lately.

So does Facebook deserve every bit of this bad press? Maybe not. Maybe it’s not all fair. But it’s all coming from somewhere- they’ve just made too many people mad. I don’t think you can insert yourself this directly into monopolizing control of information and the enormous winnings of the Internet without this happening.

Worked for a company that made extensive use of elixir. It was a disaster, not due to the technical stuff, but because of every other aspect of a technology choice:

- Near impossible to hire experienced people
- We had to write from scratch a lot of things that are "free" with rails/django/etc
- The paradigm change takes time to learn and get it right
- Some people were happy to learn it, others didn't want because they knew they wouldn't use it ever again
- Many missing libraries in the ecosystem. Some libraries are poorly implemented or abandoned.
- Googling for problems wasn't easy, there aren't as many answers out there as you can have for Rails, Django, etc...

But yes, the Erlang VM is awesome, can't disagree with that.
I also don't see anything too 'whistle-blower' worthy in the goodbye post.

It just seems to be a vague message that although social media sometimes have a positive impact, it also sometimes has a negative impact, and that Facebook has employed strategies to help it grow. Hardly shocking findings!
> some of her suggestions really do not align with what the tech community wants at all

I agree in general with your comment, but what I don't like is anyone (Haugen, you or anyone else) speaking for "the tech community". We all have different opinions, and you can't generalize with that.

For example, plenty of people I know including myself would be strongly against less encryption, but strongly for more government control of tech companies (not via less encryption but via other means).

It's really hard to generalize, and in this case we gain nothing by generalizing so let's do it less, not more.

I am working on a partial off-grid solution for my new home. I went through the TX winter storm and don't want to get caught with pants down again.

My strategy is to have a sub panel installed which runs the most critical loads:

Main Panel
- 150A
- 50A A/C
- 50A Kitchen Range
- 30A Dryer
- 30A Oven
- 100A Sub-panel bypass
- 30A Inverter/Charger
- 50A Generator backfeed (Interlock w/ 150A Main)

Sub Panel
- 100A
- 30A 220V Inverter backfeed (Interlock w/ 100A Main)
- 20A Furnace/Blower (this is the key bit for TX winter)
- All lighting/bedroom/office/internet loads
- Kitchen 120V outlets + fridge
- Garage 120V (doors, etc)

In normal operation, the Main Panel would be fed by the grid, with the Sub Panel fed by the inverter backfeed. The inverter will operate in bypass mode if grid power is available. Otherwise, batteries will be drawn from seamlessly. The sub-panel bypass (i.e. 100A sub panel main) would only be turned on if there was some issue with the inverter setup.

This effectively puts this most important parts of my house on a ~double-conversion UPS setup. I am not that worried about losing HVAC compressor, range, or laundry capabilities during a grid outage. If it gets really desperate, I could still wheel in my 12kW generator and run a load of laundry while the inverter charges things up. The reason I want to run inverter full-time is because we get shitty brownouts almost every day.

I am planning to use a 6kW inverter to run the sub panel. Still debating on the # of batteries to use, but I am going to start with enough to run 12 hours before I need generator.

And yes, I looked at Tesla power wall. I am not made of money. I am going to have this whole house UPS deal done for <8000 USD.

Finally, back-feeding panels is acceptable per code around my parts as long as you follow all the rules (e.g. actually install the interlocks). This is definitely a more grey area, but its also one of those things that is super easy to back-out if you are going to sell the house.
Most my mates who are artists, designers, writers and scientists love working late at night... See? The argument can easily go the other way around. Builders, bus drivers, farmers, etc., all have to start early, and that's understandable.

Our field of work (I suppose most readers here are IT professionals) never had to normalize fluctuating schedules until relatively recently - when our profession has become fashionably decentralized.

And I think we need to be careful and make sure that harmful practices like having too many meetings or mandatory meetings at odd hours have not become a norm.

Programmers don't create things and solve problems at meetings. Most of the time, the meetings are there for other people in the business.
