How retail tech helps brands reconnect with shoppers who’ve flown to ecommerce
Great job! Thank you.

Quick suggestion: could you show the summaries directly on your first page, without the user needing to clicks links? (Otherwise, we are back to part of the original problem: need to open many tabs to read each story's summary, or do a lot of back and forth between front-page and post's summary).

In case there would be too much text when doing this, another way to solve this would be to unroll the summary dynamically when user clicks "summary" (instead of opening a new page). Hope this is useful!
It's important to seperate Amazon the market place and Amazon the merchant here. Amazon is a market place where you can find all types of merchants. In this role, it's not so much Amazons issue what these merchants sell.

It's similar to how there are all types of websites running on AWS. Amazon is not responsible for their content.

Amazon is also a merchant on their own market place. I would expect Amazon and other big name merchants to usually sell you genuine products.
In addition to ETFs, why not go 1 step further? Offer hedge funds too. Amazon has a ton of data on which consumer brands are overperforming every quarter. Use that data to make investment decisions.
The concept is quite interesting and I like what I see so far! Signed up and attempted to share with friends. The referral link does not seem to work.

how can energy go missing because of an energy war? I found this but I don't understand: "Kosovo has been using more power than it produces while Serbia, responsible for balancing the Kosovo grid, has failed to do this, Nies said. As a result, Serbia has been free-riding on the system."

As somebody who is not familiar with medical research, can anyone tell me why the authors mention the BMI here at all? As far as I understand, the BMI is an indispensable metric for statistics on large populations. However, in a case study involving only a single individual, it seems to me that other markers such as body fat percentage for example, would be a better choice making the BMI more or less meaningless.

The Charity That Saves Lives with Radio, Not Doctors
I was thinking the exact same thing. I've always assumed that AC frequency wasn't exactly 50Hz and was allowed to fluctuate slightly.
5 years of consistent use, let's say that goes to ~180 days per year (no idea what your climate is) -> 900 days of wear. A $300 jacket would cost you 30 cents per day of usage then. Are you sure you do not spend a higher fraction of your money on ephemeral luxury like beverages or entertainment?
I think it is really old and cheap clocks (such as old radio alarm clocks) which use AC frequency for the clock signal. Their power consumption on AC is also rediculous compared to what they do (displaying the time).

Sounds great. Given that in stock market investing you are better off on average with passively managed tracker funds, there does seem to be a big gap in the market for a crypto asset equivalent. Having a crypto equivalent of an ETF as single tokens representing e.g. CMC100 would bring a whole host of challenges, e.g. regulatory, security, ease of manipulation (it is relatively easy for whales to temporarily get coins into the CMC100), etc. In the spirit of crypto, a solution you run yourself, and where you manage the keys to all the coins yourself, should go some way to addressing those concerns. Maybe in the longer term this sort of thing will be a smart contract you run yourself on a decentralised exchange to make it more easier.

Stating what you mean when you're talk of 'living', as you're doing here, is giving your definition of it.

Did I say anything to that effect? Not in the comment you're replying to.

In another comment on this post I said that a notion of 'living' is a mental construct, not an objective phenomenon outside of ourselves.

I haven't bought many clothes in the last 10 years, an item here and there. But there are others who buy new stuff every week and then stuff it away in closets. Perhaps we need to have more awareness around wasteful shopping?

Do you have a source for that? It's a compelling hypothesis but I'd like to see some data.

I find stuff like this extremely interesting.

It's incredible how connected and interdependent we have become as a society and how we only notice this if things start to break (or at least run out of spec); even if it only impacts such supposedly minor things as a clock on a baking oven.
yeah except the one in my oven, in my microwave and in my coffee machine... all late by exactly the same amount.
It's supposed to average 50Hz over time, so using it for clocks make perfect sense.
> I have a new found respect for man-made fibres like polyester, polypropylene etc as producing those fibres is so much cleaner than natural goods, and instead of having to spend a lot of energy getting the fabric to "feel" right, you just modify the properties of the fibre by changing how its produced.

I wonder how rayon fits in this picture. It's a semi-synthetic, made from natural cellulose. In terms of comfort, it is probably my favourite synthetic fibre, but the manufacturing process is still pretty nasty.

[0] https://en.wikipedia.org/wiki/Rayon
Not true. I experience this right now with the integrated clock in my stove. Applies to a lot of clocks in kitchen appliances.
Probably not considering some of these used a stepper motor to drive their clock that was coupled to the grid frequency.

These devices don't have any computing power.
Hey - I thought that this was interesting work, but just wanted to jump in and say thanks so much for the effort in reproducibility. This should be the new standard, but putting in the effort to do it now is improving the world at relatively little personal benefit. So thanks!
Only device I have is my oven that uses this kind of clock... but usually only winter/summer time alters this irrelevant to begin with. Not the mention a power outage sometimes and then months before it's set again.

Then again, what kind of more dependent systems or companies would have negative effects due to this? Besides bedside alarm clocks.
> ...digi-key have schemeit.

Last time I checked, Scheme-it was basic web-based schematic capture, not layout.
You must have a really old alarm clock. And why wouldn't you correct the time manually if you know it's drifting?
Hmm, I'm seeing 5 minutes 46 seconds, with a frequency of 50.02 Hz. Maybe they're fixing the issue?
same for me, drove me nuts. Fortunately my PC looks at atomic clocks...
That assumption is right. But until now it was always compensated, so that in the mean it would be ~50hz. This correction mechanism apparently isn't enough anymore for the current fluctuations in europe.
The real power for AC is averaged over the cycle. So the current decreases as frequency decreases.
An oil change place changes oil, and likely other fluids (transmission, radiator, etc.)

A tire change place changes tires, and likely brakes.

A mechanic shop isn't so specialized.

It's like the difference between a 7-11/corner shop and a full-size grocery store. Or between your local clinic and a hospital.
It can be allowed to fluctuate, but still regulated to keep pretty much exactly 50Hz mean value over time.
Because its reliability is happenstance.
In Holland on the first day of the month we set off all the war alarms for a minute to test if they still function. This month a lot of them failed, caused by the power frequency
My microwave adds a minute every week or so because the UK's frequency is slightly different to the the rest of the EU. The clock on the microwave I have is keyed to the continental europe's frequency rather than the UK.

It's actually moderately annoying.

It was a fairly well reviewed (cheap) machine from Wilkinsons, a budget brand. Perils of cheap electronics.

EDIT: Well sounds like it's not the case, TIL, not sure where I picked that up from.
In ordinary circumstances, the grid frequency is far more accurate than a cheap quartz crystal oscillator.
No but things like heating systems are presumably designed for 20 year + lifespans, so there is probably a large number of legacy systems out there and will be for some time.
Suppose you and I have an agreement to generate power for our neighboring households. We each have solar which works most the time, but if it's too cloudy and we're both using a little more, we'll each fire up some temporary generators to cover the loss.

You think I'm using more power than you expected when we started the agreement, but we're both spending the same amount on fuel and solar, so you decide not to fire up your generator.

The system might still have enough power to basically run everything, but it might be sluggish, you might get "brown outs" which is when lights are on but dimmer, rather than going all the way to black.

A brown out is a drastic, noticeable reduction in frequency. The grid is a bit like a wind up toy where there's a lot of potential energy in the system, but as you extract that energy for work and don't replace it, things (machines, lights) slow down before they stop.

Now scale this up from two households to millions. Deviations in frequency might be incredibly slight, and not noticeable to the naked eye. But they accumulate over time if you've tied precision equipment to the grid.

Theoretically, certain industrial machines designed to run at specific frequencies will wear faster or break when run off frequency for too long. I'm not sure if those effects generally happen at such small deviations or not.
It's interesting that fixing this delay will involve setting the grid's frequency above 50 to 50.01 Hz which will advance clocks about 15 seconds a day and thus it will take 3 to 4 weeks to bring the clocks back on time.

And they cannot set it higher than 50.01 because at that point mechanisms for bringing the frequency down to 50 would automatically kick in.

Clean iOS Architecture Pt.3: Composing Types in Swift
AC frequency makes the entire process cheaper.

You can use a resistor to lower the voltage and plug in a stepper motor and there is your clock.

When the idea was initially proposed quartz generators were also a bit more expensive so using the grid to synchronize was not a bad idea at all.

Even today it's not the worst idea since it's being kept very close to 50hz. Close enough that you can safely operate an alarm clock from it without being off to far by the end of the day.
While I am a big proponent of using UI/UX of each platform, there is a market for having apps that look the same everywhere, the beloved enterprise.

Usually either everyone gets the same kind of device, or the same UI regardless of the underlying OS.
Yeah, yeah, you now have a couple √2's because you're dealing with RMS voltages and currents, and a cos(θ) for the phase angle, but when it's all combined it ends up differing by some constant factor.
I think the real trouble with rayon, at least in my experience with it, is that it seems to be slightly less durable than chewing gum, so you have to replace the garments more often.
Basically every device that is connected to main power and has a clock skips an internal quartz based circuit. Usually, this gives much higher precision for the same price point because frequency is typically controlled very, very tightly.
You might want to look around a bit, your assumption is incorrect: there's a surprising amount of appliances that are not IoT, but do rely on such unexpected side channels such as AC-as-a-clock - not everything has a network port, a quartz oscillator or even a GPS receiver, but most appliances do have a power plug.

I think it's probably a combination of the knowledge that extreme fasting is dangerous and the myth that your metabolism plummets as soon as you skip a meal.

When I was in middle school, I remember my friend's older sister being on some kind of snack diet that was supposed to keep metabolism high by never going more than an hour or so without food when not sleeping.

I seem to remember Brad Pilon in "Eat Stop Eat" briefly mentioning the origin of the myth that your metabolism tanks rapidly if you skip a meal, but I could be wrong.

I do intermittent fasting myself, and it drives me a little crazy when my wife tries to convince me that it's bad for my health to skip dinner once in a while on one of my non-fast days.

No it's standardized. Outside of accidents the power providers take extreme care to keep the frequency synchronized to UTC. Exactly.

A clock using the power grid as reference might be off by 4 minutes over the day but on average it will be perfectly on time.
The frequency is exactly the same 50hz.

The voltage is usually 240 volts rather than 230, but within the acceptable range (which can be as high as 256).

Higher voltage is good. The kettle boils faster.

I have a family 1-password account that I share with my wife. In our shared vault I have 2 secure notes: 1 that explains the process of how to unlock my 1-password vault, and another note that highlights which of the +200 accounts are important. That last list only contains about 20 accounts, some financial, some work related. For difficult technical recoveries, I've listed the name of trusted people that can help her.

We've gone through the notes together so she knows what to do.

Inviting my parents is the next step.
Once I overcame the initial hunger feeling of the first days it became noticeable. It then increased peaking in week 3 to 5 but present even until the final days.

In the last days I became aware that every day I continued it was another day where my mind "won" against my body, and this scared me increasingly because I was no longer sure if I was still listening objectively to my body or if I was trying to prove something just for the sake of it. (e.g. "you came already that far now don't give up" -> this reasoning worked well for doing marathons sports but felt was dangerous to apply here). It was like my body telling me that it would no longer support my BS, ... but not via a hunger feeling as in initial days but I became so weak that walking more than few meters required a rest. Even speaking for more than 10 mins was tedious.

Was there ever? The Warsaw Pact countries had "communist" parties, but the country itself was usually called "socialist", and the propaganda tended to refer to "building socialism", as if they hadn't even finished socialism yet, let alone communism. So "communism" seemed to be a sort of nirvana that people were supposed to eternally strive towards rather than something that they could claim with a straight face they already had.

Anyway, China is ruled by a "communist" party, and I guess they have as much right as anyone else to decide what they mean by "communist", or whatever the corresponding expression in Chinese is.

Of course the lack of consensus about what "communism" means is as nothing compared with the confusion about what "capitalism" means. We can't just follow Marx because Marx was writing about a world (19th-century England) that no longer exists.
You sure that's the cause? The UK has legislation limiting amount of drift from 50Hz, and the Grid adjusts frequency multiple times a day, outside spikes, to ensure the cycle count is correct.
The benefits to keeping timekeeping tied to power is that often the power supply is much more accurate than any reasonably priced quartz oscillator you'd want to put into an appliance.

Uh, you're not being very clear but I feel I have to say this: some people add sugar when whipping cream, more or less automatically. It's not at all strictly necessary in order to, you know, whip the cream, but it will affect both flavor and texture. If you like your sweets, you're probably going to think that the cream with added sugar tastes better.
Would it "fix" it though? I mean I've already heard a lot of people that just reset the time on their clocks, so in 4 weeks they have to dial them back again. Maybe for unattended time keeping things?
