The most British unit of energy measurement possible. What would the American version be? Hamburger patties cooked? Smartphones charged? Highway miles driven?


While that's very British, you forget the obvious: The BTU is the British Thermal Unit.

Can't get any more British than something with British in its name. Not to mention it's very widely used in practice, though it's up there with pounds, gallons, and miles.


Spoken like a true American. Despite the name, the BTU is an American customary unit, used almost exclusively in America for measuring the power of air conditioners. In practice, it's not quite extinct in the UK as gallons are, but it's on the way.


The other weird unit for measuring air conditioning is "tons". One ton of air conditioning has nothing to do with the weight of the air conditioner. Instead, it means the air conditioner provides cooling equivalent to one ton of ice per day. One ton is almost exactly 12,000 BTU/h; curiously, the round number is a coincidence.


I think it might be more extinct than gallons, tbh. People still talk about miles per gallon a bit (note that, for extra confusion, a UK gallon isn’t the same as a US one) but _very_ few people would have reason to think about BTUs these days, I’d have thought.


The American version would be number of football fields smoked.

But you have to further specify whether you're using Carolina freedom units or Texas freedom units, because the two groups can't agree on whether it includes the end zones or not.

We tend to use homes powered. Which seems logical enough, until you realise there is a built-in assumption of 4,000 kWh/month homes.


> until you realise there is a built-in assumption of 4,000 kWh/month homes.

No idea where you got that figure - you're off by a factor of four.

https://www.google.com/search?q=US+electic+usage+per+home

For example:

> The U.S. Energy Information Administration notes that the average homeowner used about 914 kWh per month in energy

and https://www.eia.gov/energyexplained/use-of-energy/electricit...

It should be noted that the average for an apartment unit in most of the country is half that, and a substantial portion (40%) of the US population lives in apartments.


Perhaps they are conflating it with annual electricity consumption, which is about 4000 kwh per capita per year

> No idea where you got that figure - you're off by a factor of four

From facts, yes. Forgot where I recently saw it, but it was in the amount of energy a datacentre in the South burns. Work backwards from the PR stats, and you get a moderately-large American house’s energy footprint.


holy tamole...

I think we use around 700-1000/month most months. who is using 4000/month?


Replying to myself:

I guess... there's only two adults in the house here, and a 2000 sq ft house with two heating/cooling units (up/down) and relatively modern windows/sealing.

I think this month will be 1200, and I think we'll have a couple more 1000-1200 kw/h months up ahead.

EDIT: https://www.eia.gov/energyexplained/use-of-energy/electricit.... This shows the average being 10500 kw/h/year, which seems to be in line with our use case. That average is including all housing types (apartments, detached homes, etc).


1) big houses in the south with lots of AC.

2) at least one house in Pittsburgh that runs a few GPU servers for its owner's startup. ;) (not quite 4000, but over 3000 this month including our normal use and ac)


I live in a 1900sqft house of 4 people (and lots of electronics) in FL and we used 2477kwh last billing period. Our low period is about 1370kwh.


Our lowest/highest are 1800/3300 for a 6 adult FL household. Our lower number was 1700 but our winters keep warming.


Standardized Texas A/C hours.


If we're firing shots anyways, go with mobility scooter miles.


Surely in the case of firing shots it would be number of rifles manufactured or rounds produced.


Sure, use round numbers.


Too many holes in this idea.


It's also the British billion which is larger than the American billion.


It's probably not, unless you've calculated that it is? It's not at all common any more, led by financial interoperability I think.

(Unfortunately in my opinion: it seems more logical than the American/standard billion. We go up to nine until we run out of units and start on tens, until we run out at nine tens and nine and start on hundreds, until we run out at nine hundreds and nine tens and nine and start on thousands, until we run out at nine hundred and nine tens and nine thousand and nine hundreds and nine tens and nine and start on millions. Why then only go to nine hundred and nine tens and nine million (...)? It breaks the pattern of using all the expressable numbers until you run out and have to start a new word.)


True, but the pattern would break down with (the long-scale) definition of trillion in any case.

The long scale makes sense because it is powers of a million -

- one million - 10^6,

- one billion (long scale) - 10^12 - ‘bi’ meaning two, is a million squared,

- one trillion (long scale) - 10^18 - ‘tri’ meaning three is a million cubed,

- one quadrillion (long scale) - 10^24 - ‘quad’ meaning four is a million to the power four.


In each step of the American system, you go up by a factor of 1000 each time. There is no discontinuity.

The problem was that there were once two billions, the short billion and the long billion. The English world decided to use the short billion and the French world decided to use the long billion.


Long-scale billions are essentially never used in English, and for official purposes the UK switched to short-scale billions in 1973. So, er, probably not.


How does 6lb of gas release 20lbs of CO2?

I found this[1] link from the EPA with a number similar to yours, 8.8kg per gallon of gas, but they say it "creates" rather than "emits." I'm still struggling with this creation of mass out of thin air...

[1] https://www.epa.gov/greenvehicles/greenhouse-gas-emissions-t...


It's because the majority of the mass of CO2 comes from the oxygen from the air used to burn the carbon. So in this case, it's quite literally creating mass out of thin air.


Specifically, the atomic mass of carbon is 12 and oxygen is 16. So for CO2, 12/44 of the mass is carbon, or about 27%. So of that 20 pounds of CO2, about 5 1/2 pounds are carbon, the other 15 pounds is oxygen sucked out of the atmosphere.


"Out of thin air" is right :-)

The CO2 contains mass from the atmospheric oxygen consumed during combustion. 12 grams of carbon becomes roughly 44 grams of carbon dioxide when it burns.


"produce" is probably a better verb than "release" in this case, for the common person to understand what's going on.


I have had a 43" monitor at work and at home for a while, and the solution I've used throughout the pandemic has been to share only a region of the screen, or to share a single application or window, which I often shrink down to a "laptop" size" in order to share my screen with colleagues. That still leaves plenty of real estate around the "shared" window that is not visible to others, but is useful to me.

This is important now as schools are working to figure out how to place desks so that each student is 6 feet apart from their peers.


The article mentions their increasing focus on Azure.

I'm amazed by the number of people we're talking about. If you follow the links in the article back a few years, it appears Microsoft has laid off close to 30-40,000 people in the last 4 years, less than half of which were from Nokia. But with a global workforce in the range of 120,000 people, I guess that's not completely out of proportion.


If that number doesn't include the new layoffs. Then I dont know, ~20K lay offs excluding Nokia and including this new one does seem like a lot for 120K employees. Over 15% in 4-5 years.


Presumably OP is referring to the walled garden of CompuServe, Prodigy, and others where you could only talk to other CompuServe customers on their proprietary message boards. If you wanted to talk with someone else, it was impossible (until later) because the systems didn't interoperate. CompuServe controlled the message boards, and could control which ones were created (or not created) and thus controlled the message. Not maliciously, just as the nature of their product and the state of technology at the time.


I used AOL and Compuserve, but after they had both expanded to allowing access to everything. What drove the expansion? It seems like the market worked as expected in this case...


The existence of the open internet made it beneficial to interoperate; lack of it would mean that the expected market interest would require them to not interoperate.

For many markets, the natural consequence of unregulated free market conditions is to aggregate towards a monopolistic or oligopolistic market, which isn't a free market any more. The idealized economic free market isn't a stable equilibrium - it's a good position for society, but it doesn't stay there on it's own, it needs to be kept free by preventing it from devolving into the monopolistic optimum.


What was the 'open internet'? I genuinely am not comprehending what drove AOL and Compuserve to tear their walls down.


While the internet as such existed, at the heyday of AOL&Compuserve residental users were not able to get a connection to internet as such at reasonable prices.

By the 'open internet' I mean the arrival of ISPs who offered consumers direct connectivity with all the internet, competing with AOL who offered connectivity to, well, AOL.


And what created the existence of the open internet? Voluntary interaction.


Wrong - benign neglect.

The fact that the consumer was more nimble and capable of exploring and creating value in this space allowed them the chance to beat the entrenched players.

Today those entrenched players have finally turned around and are using their legacy power, connections and money, to make it an unfair playing field.


When the web came along the walled gardens were immediately obsolete. By the time you joined they were trying to stay relevant by becoming portals to the web. Some people were actually fooled into thinking AOL was the web for over a decade afterwards.


Not a valid analogy. AOL, Compuserve, et. al. didn't own the wires entering your house. Comcast, Verizon, et. al. do. The barrier to entry to start an ISP in the days of dialup was much lower.

The "free market" will not be a savior here.


"others where you could only talk to other CompuServe customers on their proprietary message boards."

In other words, Facebook and Twitter.


No. More like if you are on Comcast, you can't access Twitter. If you're on AT&T, you can't access Facebook. When you sign up for your ISP, you get to choose between Amazon and Netflix, and you can't change your mind without paying someone to come out and lay new line if you're even one of the tiny few lucky enough to have more than one ISP that serves your home.


I don't know if this particular legislation would allow this, but this the path that I fear we're heading down.

The flyer you'll be getting from the company who owns the line coming to your house: https://imgur.com/muJfxMQ


If Facebook and Twitter were also ISPs and you could only intereact with them and not with any other social networks.


But isn't that the idea behind Rails? Opinionated defaults with a config to change the setting somewhere?


Yes, but at some point you can't just go around installing all the possible extensions/gems/whatever that you think are "good". The default gemfile would be 300 lines long with "developer happiness" gems such as `oink`, `bullet`, etc etc etc.

Most of the things that Rails is "opinionated" about are far more arbitrary than this, like whether the database primary key should be “id”, “postId”, “posts_id”, or “pid”.


> Most of the things that Rails is "opinionated" about are far more arbitrary than this

To my eye, at least, it isn't a matter of being arbitrary, but rather not having an answer.

PK names don't matter to the machine, so long as everything agrees and modulo illegal values. Humans get massively opinionated, but the machine doesn't care.

Compare with: How long should a query take to run? No, I'm not going to tell you what kind of query, or the size of the dataset, or the hardware at the bottom of the stack, or what the app is actually doing.

It is like asking what specific clothes an arbitrary person should wear.


The key is, I think, the "opinionated" part. Something like "how long should the DB statement timeout be" isn't really something people would have a general opinion on.

Also this stuff is all heavily Postgres specific; I think @nateberkopec's estimate of 300 gems is probably too low, even if you limit it to only say the top five most popular datastores.


Food was by far our largest expense, but not because we choose the fancy fish and steak options. Instead we picked lots of food we wished we had been served at weddings we had been to. Tasty comfort foods, like a mashed potato bar (add your own toppings) and buffalo chicken sliders and lots of little tapas-style treats. We got so much positive feedback on the simple items, and continue to do so to this day. So glad we resisted the urge to serve uptight "fancy" selections!


Yeah, you did it right in my opinion. Good on you for resisting the urge to make everything fancy.


They aren't using popular attachments. They are using customized attachments from the actual compromised sender. I commented elsewhere in the thread, but once they gain your credentials, they will go into your account to get one of your attachments, and then email a screenshot of that to your contacts, some of whom may have already seen that attachment.


Sure, but the chrome around the image is still "trusted attachment" chrome.

I get it that the browser ppl will say only their chrome is trusted, but when someone is using your app, your app's internal ui affordances receive that same level of trust in your users' minds.
