Based off the balance sheet FTX may have peaked (September 2021) with more than $100 billion of paper gains in "less liquid" assets.

  Token   Last wks  Last wks  Estimated   Peak     Peak         Peak
           value     price     holding    price    date         value
  FTT     $5.9bn    $24.00       246m      $77.69  09-Sep-2021  $19bn
  SRM     $5.4bn     $0.75     7,240m      $12.50  13-Sep-2021  $90bn
  SOL     $2.2bn    $32.00        70m     $258.78  07-Nov-2021  $18bn

But FTT/SOL/SRM is not very liquid. So you use your liquid assets (i.e. your customers' USD, USDT, BTC and ETH). People might wonder where you get all this cash. You don't want to admit you are using customer funds and you only have gains on tokens you printed. So pretend you're genius trader and run a highly profitable exchange.

You might be referring to David Mackay's excellent 2008 book Sustainable Energy – Without the Hot Air - https://www.withouthotair.com

In the book he tries to determine if renewables could support UK's energy needs. He estimated the UK consumes about 195 kWh per day per person (food, transporation, heating, miltary defense, ...)

If the UK massively invested in all the renewable options it stacked up to 180 kWh per day per person (obviously he provided lots of caveats).

His assumption on Solar PV was covering 5% of the UK land with 10% efficient PVs (about 200m2 per person). He estimated that could contribute 50kWh/d/p.

In the 14 years since the book was published it seems like Solar PV efficiency is now commonly 17-19%. So might only need to use 2.5% of the land.

@iamben at current GBPJPY exchange rate of 138, ¥15m total comp would be nearing £110k.

I am out of touch of FAANG senior dev salaries are in London now. Does that sound on par?

I also have not seen many vacancies advertised at that level. But I suspect there are roles for people with the right experience. The roles are getting filled by recruiters approaching already employed people.

My guess is a very experienced developer that speak English and Japanese can get base salaries above ¥10m at FAANG in Tokyo. So probably ¥15m with bonus and RSUs is obtainable.

I think the only email services that are not going to mine your emails for valuable data are paid services that have made strong commitments to privacy. This was an interesting podcast interview with founder of Fastmail https://overcast.fm/+Hbyc810T0

The founder was interviewed on this podcast - https://overcast.fm/+OBZna2NS8/5:16

To summarise points that are missed in the comments and maybe not well describe on the website:

This is based in Canada. The vast majority is heavy oil in unconsolidated sand. This cannot be pumped, so there are commonly no pipelines.

During the process of extraction a lot of low value methane escapes from the oil. Canada has limits to the amount of venting a well can do, so if they reaches the limit they have to either slow the well's production or spend money on building a flare.

Both options have an economic cost. These mining units are addressing this.

Thanks, I didn't know that. I've changed to the standard "Expanded Control Strip" and it is much better. I found the constantly updating touchbar visually distracting.

In the context of Rails applications hosted on EC2, then I've not found Ruby's memory usage to really be an issue. In my experience most Rails apps range between 150-500MB per instance.

My current employer typically uses M5 instances which have a ratio of 1 vCPU : 4 GiB Ram.

Running Unicorn you'll probably only want 1.5 instances per vCPU. Even a memory heavy Rails app is probably only going to utilise ~20% of the available memory.

Running threaded Puma, you probably want only a single process per vCPU and maybe 5-6 threads. In my apps running 5 threads per process typically increases memory of the process by 20%. So in that instance you'd only utilise 15% of the available memory on a M5 instance.

If you are having memory issues on Rails, then quick wins are upgrading your Ruby version. I saw 5-10% drop in memory usage with each of the major version 2.3.x -> 2.4.x -> 2.5.x.

Also if it is an old app, check you've not built up cruft in your Gemfile. Removing unused gems can be another quick win for reducing memory usage.

I see a previous post with a related issue https://news.ycombinator.com/item?id=18064899

PayPay is a joint venture of Softbank and Yahoo Japan created in June 2018. It is another cashless payment system. But what seems different is they've launched with a very aggressive marketing campaign in Japan.

Total budget for the campaign is 100億円 (億 = 10^8 / ~90m USD). They are giving ¥500 (~$5) to signup. Then 20% of the value of purchasers back in points. Then for customers of some Softbank/Yahoo services they are offering 1 in 10 chance of 100% points back. That effectively gives you an expected points of 30%.

A lot of the major stores are accepting PayPay and the store's own points campaigns are still valid.

Lots of consumers seem pretty excited https://placeuveneverbeen.co/paypay-macbook/ https://www.youtube.com/watch?v=rUKsTwg716M https://www.youtube.com/watch?v=5mC26FFNb_Y

It seems like a good way for Softbank to burn a lot of cash and spend a high price on customer acquisition. I am not sure how sticky people will be to the service once campaign ends.

Can see the game in action here - https://www.youtube.com/watch?v=xnIfCG2dga8 their level 4 was nice.

A few more details from an article in the Guardian:

---

The Guardian US is based at one of the many offices run by WeWork in New York City. Currently on the event schedule is a TGIM with Capital One event that promises “mini doughnuts and bacon, bacon, bacon”. This is one of many events promising to serve meat at WeWorks across the world – even as the policy was being announced, at the Corrigan Station WeWork in Kansas City lunch is being provided from Monk’s Roast Beef as part of “food truck Friday”, for example.

When the Guardian spoke to WeWork about whether these events would be cancelled, a spokesperson said they would not, and clarified: “This policy only applies to events paid for by WeWork. Members and employees are welcome to bring in meat for meals, and members are welcome to serve meat at events they host … we are working with vendors to align our commitment for previously scheduled events, and meat will not be served at events hosted by WeWork moving forward.”

The message Gmail presents is:

This will allow APP_NAME to: Run as a Gmail add-on [More info] View your email messages when the add-on is running [More info]

-------

The '[More info]' tool tip presents:

Allow this application to view your email messages when the add-on is running Access is temporary; only available to the add-on when it is running within an opened email

-------

I think for your typical user that is not making it clear that 'employees at APP_NAME can read your emails'.

How much is your rent? How much short are you from paying the due rent?

If your rent is at low-end for your area, then I'd try to avoid getting evicted. Getting evicted could trigger more expenses (moving costs, new deposits, etc.). Putting you deeper in the red.

I'd first sell everything non-critical. If you get evicted a big pile of possessions is going to be a burden anyway.

I found hotel pricing vs airbnb varies greatly depending on the season. In low-season often hotels are cheaper. Hotel's have large fixed expenses and are often happy just to fill rooms at any price.

Not sure how accurate but napkin maths and quick google suggest barrel of oil produces 118 kg of co2. So about 9 barrels to produce a ton. Barrel is $67. So cost of capture might add 15% to 38% to cost of oil.

An exchange could mitigate this attack by also monitoring the outflow by 'age'. Delaying any large withdrawal of 'new' coins.

* AGE: i mean, how recent was the deposit of any coins involved in any transaction. So if I send a large quantity of Bitcoin Gold to an exchange (they are marked as 'new'), then if I immediately exchange them to Ethereum, the Ethereum is now also considered 'new'. If I try to withdraw the Ethereum the exchange delays withdrawal.

I wonder if we could see a spiral that effectively kills off smaller coins?

Exchanges respond to these `weak` coins by increasing their confirmation requirements. Some of the really small coins would probably need huge numbers of confirmations. Lots of confirmations, which would likely damage the value of the coin. Lower price would reduce the miner hashrate Lower hashrate would further lower cost of 51% attack. Exchanges increase confirmations further

Is it common to get additional grants during that first 4 years?

So the article should really be about 'Why are diapers so expensive in the US compared to Europe?'

Here is another example from a UK suermarket https://groceries.morrisons.com/webshop/product/Nutmeg-Nappi... which is 0.075 GBP (0.10 USD)/diaper.

The UK doesn't charge sales tax on nappies/diapers - https://www.gov.uk/government/publications/vat-notice-714-ze... which may explain a small part of the difference.

Are you paying via debit card? Might be better to get a good credit card. Plenty offer decent exchange rates for foreign currency transactions https://www.moneysavingexpert.com/credit-cards/travel-credit...

Also as a codebase grows the complexity grows. Adding or changing code has a lot more impact and is much harder.

If I remember correctly Shopify is something like 400k lines of Ruby on Rails code and 400 developers (i.e. one developer per 1000 LOC). Whereas I guess a 5k LOC codebase could be handled by a single developer.

That house is a small single storey building with only a ratio 33% internal floor space vs plot size.

Here is what $2m house looks like it good neighbourhood of Tokyo https://www.homes.co.jp/kodate/b-75250036569/ 2100 sqft (195.75m²) of internal floor space squeezed on to a plot that is only 960 sqft (89.26m²). That is 218% ratio.

Is that the typical building density in Silicon Valley? If so, then not surprising it is so expensive. In Tokyo that plot might get divided into 3 and three good size family homes built on it.

From the satellite view on Google Maps it would appear this building uses only a third of the land of its plot. So maybe plot is about 2550 sq ft.

Just some rough numbers for you:

A GTX1060 6GB can mine ETH at around 80 watts. And currently, earn you $25/month of ETH with electricity costing $10/month. Cost of card is $260.
