One can look up the utf8 character for different typographical characters and copy and paste them in. On macOS at least, there is a keyboard shortcut for "emojis" (Cntl+Cmd+Space) and a little window shows up where you can search for emojis by name, and typographical characters by name (such as "em dash"). —pjh

> One can look up the utf8 character for different typographical characters and copy and paste them in. Haha, yeah, that's what I usually do. But it's arduous enough for me not to bother for a HN comment. That's why I brought it up. I love macOS' emoji picker thing, I wish there were something like it on Linux.

Bring up the keyboard viewer widget on macOS and it will show you a live preview of what each key is... you can hold down the modifiers to see how the keys change.

Also—FWIW—an m-dash should not have whitespace on either side, at least, not in America. :-)

Nah, its all toys for lazy impatient kids. Real coffee needs slow and thoughtful preparation in a cezve.

Them is the fighting words considering a moka pot is there!

Maybe I'm doing it wrong, but I've never gotten anything I would consider drinkable from a moka pot.

The point about the newer Bialettis being cheaper is absolutely true. My mother has an old (>10 years) Moka that feels heavy and sturdy. A couple of years ago, after accidentally leaving it on the stove for too long, the bottom chamber and the filter basket got a permanent burnt coffee taste, and we bought a new one to replace it. That one was lighter and came with a significant thinner filter basket, which I also at…

You see a similar thing with the glass chemex. There is a healthy market on eBay for pre-1980 models that were hand blown from great quality glass. My wife got me one for a gift and the difference in feel is remarkable. New ones feel fragile, this feels solid and strong. I’ve broken two of the newer versions and it’s dangerous. The old one is still standing strong in my house, surviving trips in my RV, and generally…

Such a cool idea, and attractive images. However I’m kind of disappointed they mostly picked things that are fairly simple, transparent or openable, and look exactly the way you’d expect them to inside. I assume some combination of cost & size drove this. A vintage espresso machine with 1 group head would be more novel, for example.

You just reminded me there's a video on youtube of a guy literally tearing a Juicero apart and it's hilarious: https://www.youtube.com/watch?v=_Cp-BGQfpHQ

The auto-generated captions have a scunthorpe problem; censoring a British & Australian term for a cigarette that has a more offensive meaning in the US.

Holy shit that's amazingly funny.

My personal highlight as he's pushing the button wildly, "oh for fuck's sake. The mash harder button. Es funktioniert nicht"

Also subtly hilarious that the machine more and more covered in root juice as he goes. God that's good.

> "With the powerful 1200 W heating element (the thin coil wire), the kettle reaches optimal temperature very quickly — in under three minutes." Europeans (and other countries with ~230V household sockets) would consider this quite poor performance for a kettle. 3000 W kettles are not uncommon here in the UK!

I have this kettle, and its selling points are: temperature control, ergonomics, and the steady, controllable flow rate. Using it is pure joy!

It reaches the desired temperature before I'm done preparing everything else (throw the beans in the grinder, pre-heat the V60, etc), so it does not matter that it can't draw 3kW.

For how much love went into the imaging and description of everything, the actual coffee knowledge is maddening.

You want your water in your Aeropress to be as close to boiling as possible if using lightly roasted beans (which I'd wager is most of Aeropress usage)! None of that 80-85 degree celsius nonsense.

Similarly, their description of ceramic burrs is bizarre. Ceramic burrs are not considered "better" than stainless steel ones! If you look into high-end grinders sold for hundreds and thousands of dollars (both commercial and "enthusiast" ones), they will all have stainless steel burrs!

And don't get me started on their description of conical vs flat burrs...

> European plug sockets are typically rated for 16A, secured with a matching breaker and allowing for about 3500W of power. Appliances that use the full 3500W are rare but they exist, so it is not like it is illegal. So why don't Europeans get the 3000W kettles too? The British plug (and ring wiring scheme) was designed for two 13A electric heaters on a single ring, so continuous load. Meanwhile, German Schuko and th…

I think - I am an electrical engineer working in the offshore industry, so I have only superficial knowledge of shore-based installations - anyway, I seem to recall that the Norwegian electrical code calls for Schuko not being used to carry more than 10A continously, 16A intermittent. However, until relatively recently, the average residential circuit was 10A, though you could get 16A if you asked for it - typically…

In Sweden (Schuko), 1.5 mm² wall installations are rated for up to 13 A now, but used to be 10 A. It's the wires in the walls being the bottleneck, not the connectors. Dunno why they up-rated it. Can't imagine the copper is better now than it used to be.

UK plug sockets are rated at 13 A, giving a maximum power rating of 2,990 W. Kettles are consequently amongst the highest-drawing household appliances in the UK. Back when there were only three television channels, the National Grid planners used to pore over the Radio Times, looking for popular programmes like the Morecambe and Wise Christmas Special (21 to 28 million viewers in 1977), so they could prepare for the…

Is there a reason why European kettles are typically 2200W and UK kettles are 3000W? European plug sockets are typically rated for 16A, secured with a matching breaker and allowing for about 3500W of power. Appliances that use the full 3500W are rare but they exist, so it is not like it is illegal. So why don't Europeans get the 3000W kettles too? Maybe some people have 10A circuits, maybe this is a margin so that ot…

I am an electrical engineer who has to learn all those norms.

The normal eueopean "Schuko" plug is rated for 16A short term and 10A long term. Long in that context means everything above 1 hour of continous load, which should cover typical applications of water cookers.

The wall sockets are typically the same, although 16A continous variants exist and old wall sockets with bad contacts can easily heat up enough that I would avoid ever going over 10A with them if it can be avoided.

Proper storage is just pulling the plunger out entirely. Every few years, soaking the rubber seal in mineral oil overnight then cleaning will restore flexibility (otherwise it shrinks over time, reducing the quality of the seal). Unrelated: using paper filters is less eco-responsible than the gold foil filter, but makes for better coffee.

A year's supply of paper aeropress filters weighs about 1.4 oz. This is significantly less paper than a single Monday New York Times, so if you've ever read a paper newspaper, you've eco-sinned more than drinking a year of aeropress. Indeed, the paper is so little that I'd be really surprised if the ecological impact of mining and making that metal filter will ever be recouped. It's a little how cotton groceries bags…

>It's a little how cotton groceries bags are so resource-intensive that you'd need to use them hundreds and hundreds of times before they're better than daily plastic bags. (Litter aside, which isn't an issue with paper filters.)

It doesn't seem unreasonable to use a cotton grocery bag hundreds of times. That's only a few years of weekly shopping trips.

Regardless, litter from improperly discarded plastic bags was the primary motivator of their regulation. It was not intended to be about resource use or carbon emissions or whatever people are focused on today.
