athrun··on 2,050-year-old Roman tomb offers insights on ancient concrete resilience
Another example is their mastery of acoustics. I remember visiting ruins of Roman amphitheaters when I younger, and getting surprised at how they had managed to design them so that the audience would clearly hear what was happening on stage, even from great distance.

I was told it was not entirely clear to us what key principles they were following to get the acoustics working so well and that a lot of their wisdom had been lost to us.

It was like 25 years ago, so I hope we've made progress in rediscovering some of these techniques. But still...

athrun··on Kraken Security Labs Identifies Vulnerabilities in Commonly Used Bitcoin ATM
If you use a service that handles your private keys and the service gets compromised, then your funds are gone, permanently.

This is a very different risk proposition compared to trusting a bank. If the bank gets compromised, it's the bank's problem, not mine.

athrun··on Domain-Driven Design
I recently came across this talk from Scott Wlaschin titled "Domain Modeling Made Functional".

I found it a great practical introduction to DDD.

athrun··on Culdesac Tempe: The first car-free neighborhood built from scratch in the US
It's great to this an initiative like this.

Are you guys in touch with the StrongTowns folks at all?

athrun··on Growing object-oriented software vs. what I would do
A lot of wisdom to unpack here. Thank you for sharing!
athrun··on Cities Are Not Loud: Cars Are Loud, and Places Without Cars Are Quiet [video]
I hope you realize that restaurants and other small businesses provide tax revenue to the city, while parked cars usually don't (in most places).
athrun··on Cities Are Not Loud: Cars Are Loud, and Places Without Cars Are Quiet [video]
I hope you can realise that the issue pointed out here is that the surburban development pattern essentially forces you to take your car to do something as basic as grocery shopping or going to the park.

If your neighborhood was walkable and you had access to shops within walking/cycling distance, you would not need your car for this. It might even be more enjoyable for your family than sitting in a car, stuck in traffic.

Heck, your children could—gasp!—go get ice cream at the corner shop by themselves!

athrun··on Instructions show how cops use GrayKey to brute force iPhones
It's interesting how the instructions say that an agent can be installed on the phone even _before_ attempting to brute force the password.

How can an application be installed if the phone is locked?

athrun··on Amazon Sidewalk
Seems challenging because we’d need to first agree on the definition of “original”, “done” and “good”.

Also, the original iPod had less space than a Nomad. Lame.

athrun··on Apple M1 Assembly Language Hello World
Yes I think he's getting some of terminology wrong.

Saying that "Linux [is] based on Unix" is not really accurate either.

But ultimately this is just nitpicking. It's great that he's sharing what he learned.

athrun··on Aquafaba
What a very interesting topic.

I found a more recent paper [1] that concludes it is beneficial to soak the beans and then discard the soaking water prior to cooking.

I prepare dry beans regularly and almost never discard the soaking water. Time to reconsider!

athrun··on Amazon destroys $1.5m of sellers inventory – now homeless
While the delivery times are not great yet because a lot of items come from abroad, their inventory is now pretty extensive.

In these COVID times, I've been buying quite a bit of bicycle gear & parts and in many cases I could find stuff on Amazon at lower prices than AU specialist online shops. It certainly was not the case just a couple months ago.

I reckon Prime Membership in AU is now very worth it as you get free international shipping for orders over $49, in addition to free expedited domestic shipping and Prime video access.

athrun··on Silicon Valley pay cuts ignite tech-industry Covid-19 tensions
Yes but that's part of the equilibrium I suppose.

Places where current wages are low are going to see wage increases (because of higher demand / lower supply), which in turn will lead to an increase in costs of living.

Places where current wages are very high are going to see downward pressure on wages (because of lower demand / higher supply), which in turn will eventually lead to a lowering of costs of living.

Obviously that's valid in the "fullness of time". How long it can actually take for this new equilibrium to be fully realized is anyone's guess.

athrun··on A grim outlook on the future of browser add-ons
At the same time, there's never been so much open-source software and hacker-friendly hardware available.

It's true that the average computing device is turning into an appliance (is it a bad thing?), but it also appears the options for DIY are ever-expanding.

athrun··on Banks create money, but it's less impressive than it sounds
I found this paper from the Bank of England very enlightening when it comes to the actual mechanisms of money creation and their limits.

The paper is short and concise enough and the diagrams are very helpful to the uninitiated.

athrun··on Firefox 80 and my confusion over its hardware accelerated video on Linux
Thank you for sharing your project!

Very cool to see a combination of low-level Linux kernel APIs and .NET.

True hacker spirit right there!

athrun··on Ask HN: How does onlyfans.com work around the “no porn” Stripe rule?
Storing the CVV permanently is indeed strictly forbidden. The CVV is not used for purchases on a stored card.
athrun··on New case studies about Google’s use of Go
I don't know about that. I find relentless cynicism/negativity to be much more difficult to ignore than positive comments. I tend to think this is how we are wired as humans.
athrun··on New case studies about Google’s use of Go
Can I ask which reactive-style console UI library you have been enjoying using? Or was it a custom thing you made from scratch?
athrun··on Stripe Hires AWS' Mike Clayville as Chief Revenue Officer
It's not quite the same, but you can get the PDF from the Invoice object and send your own emails.
athrun··on File System Interfaces for Go – Draft Design
> And further, Cloud file systems do have mode, and directory...

The most popular cloud file system, S3, doesn't have folders. It has prefixes, but if you treat them like folders, you're in for a lot of pain.

athrun··on Two Months with Powershell on a Unix
Yes, this is what the parent meant: it is valid PowerShell. It wouldn't work by default in Bash unless you had `dir` and `select` defined there somehow.
athrun··on Two Months with Powershell on a Unix
It's because it's a PowerShell syntax. What the parent meant was "here's how to write it in PowerShell so that it still has a 'unix' feel to it (ie: composing commands with pipes and option switches)".
athrun··on I Miss Microsoft Encarta
Thank you for sharing this video! It certainly clicked for me.
athrun··on Stripe's API was down again
what happens when the vault goes down?
athrun··on AWS Control Tower
In addition to the resources other commenters have listed, there's also the Price List API: https://aws.amazon.com/blogs/aws/new-aws-price-list-api/

It provides both pricing and product information, so you can build your own dashboard/tooling if you want to.

If you want to skip the 1 hour delay, you can manually finalize the invoice:

athrun··on PayPal vs. Stripe for small businesses in 2019
This can be done with the new version of Stripe Checkout - it’s essentially a hosted payment page.
athrun··on China’s Plan to Build the World’s Biggest Supergrid
I've never been to New York and Boston, so I cannot compare.

I've been multiple times to San Francisco and Seattle though, which I still consider to be first-tier US cities and their overall infrastructure* is certainly no match for Western EU's first-tier cities.

IMHO, one area where US infrastructure is markedly superior is the financial infrastructure (availability of capital, legal system) which is on the intangible side of things.

* Roads, Rail, Power Grid, Water Grid, Fiber networks, Public transport, Schools, Hospitals, Police, Fire Departments

Note that you can add The Economist's audio feed to your Podcast app. So your 1 and 2 can be the same :)
