crenwick··on USB-C for Lightning iPhones
This is also the case with Apple wired usbc headphones. Probably the phone software and not the adapter.

Reminds me of when Android phones used to do the same with analog audio jacks.

crenwick··on Embedding Python in Elixir, it's fine
I feel like this project and blog post was made specifically for me. Can't wait to use this, thanks!

I ride Amtrak monthly, this is not true. Like every other train, ticket checking always happens while moving.

I gave it a shot by using phrases that avoid negation like “without”

crenwick··on Elixir 1.17 released: set-theoretic types in patterns, durations, OTP 27
I really appreciate that you took the time to clarify this. I was surprised by parents comment about needing auth twice but they seemed confident. Honestly worried I have apps with auth gaps!

But what you wrote matches my understanding. I have some routes that are pure LiveView and some that go through controller routes with HTML, and it was clear to me where I needed auth when I made them.

crenwick··on We reduced the cost of building Mastodon at Twitter-scale by 100x
Congrats on the launch. Great read.

Is there any rough infrastructure cost comparison?

Excluding the cost of engineering effort, which I understand is the major pitch.

crenwick··on Revenue is easy, profit is harder
I think you’re right on most accounts.

Yes, articles like this seem rudimentary to folks with MBA/accounting backgrounds.

Yes, tech startups can get millions in seeds funding, even where the company doesn’t have a CFO (or anyone with an MBA).

However, at those super early stages for sw startups, it doesn’t really matter. The money is to finance a product, prove the product’s value, and build a team. And its that journey where that company may start looking for a CFO.

By the time that company is raising a series A, they should have these things worked out.

Nice. A while ago I made a similar graphic as an iPhone widget.

I found it useful to have the reminder when I picked up my phone.

crenwick··on Bitwarden: Generate a Username
For one, its built right into the UI so you can generate a name and save it in the bitwarden username field in the same motion.

Also, the password generator isn't configured to work for the use cases here (adding your email or a catchall, using less characters, no special characters, etc.). That way you can still sign up for accounts that require email verifications.

crenwick··on Design and Prototypical Implementation of an IRC Chat Server in Erlang OTP
IIRC that was a DNS issue, which is why it took down all the Meta services. In other words, the WhatApps Erlang servers were probably happily humming away.
crenwick··on As an investor, why is crypto so hard to value?
The author is a value investor, which is an out dated death cult among equity investors at large. You’re spot on to question his importance of measuring equities via dividends. He also places value on metrics like P/E, which has never (“never”, like since the start of the US stock market) been an indicator of a strong stock.
crenwick··on $1T flowed into stocks in 2021, greater than last 20 years combined
> Stragetists at JPMorgan also recently commented on the rush into stocks, noting that the flows have been driven by retail investors.
crenwick··on Judge in Fortnite case holds Tim Cook's feet to the fire
I agree that it's a fundamental problem and anticompetitive behavior but I don't think it's as clear of a court case as this Epic v Apple.

Users don't need to install the Amazon iOS app, instead they can use Safari where they can buy books and ebooks directly.

Games like the ones Epic makes, however, cannot run in Safari. They are forced to go through Apple store and play by Apple's rules.

C# or maybe Node with typescript.
crenwick··on Greenland ice has shrunk beyond return, study finds
“widespread retreat between 2000 and 2005 resulted in a step-increase in discharge and a switch to a new dynamic state of sustained mass loss that would persist even under a decline in surface melt.“
crenwick··on When you type realty.com into Safari it takes you to realtor.com
This behavior sends me to undesired pages on a daily basis. Thank you for finally telling me what causes it!

It essentially makes basic keyboard shortcuts useless on safari.

crenwick··on Show HN: Turn your SMS into postcards for your grandma, every month
Images I post to social media are already on my phone, so I just use that. However I think most mobile apps allow you to 'share' photos with a phone number via SMS.
crenwick··on Show HN: Turn your SMS into postcards for your grandma, every month
OP here.

Built this to solve my own problem: remembering to send updates to my across-country grandparents.

Instead of trying to teach them how to use instragram/facebook/twitter/snapchat to see my updates, I thought it would be easier to convert my digital updates into an experience they are already used to: mail.

Every month, the services sends an SMS reminder to reply with a picture or two + a caption. We then hand design the postcards and ship them to your recipient.

Though the product & designs are built for the elderly, we also have a few customers using it for other loved ones in their life.

While nothing beats picking up the phone to call my grandmother, I've noticed that sending monthly postcards makes it easier to contact her. I now have less guilt about being in touch with her so I have less anxiety about calling her. It also gives us topics to talk about—she asks me about the pictures I've sent her.

My alias are one or two letter shortcuts for the verbose command. When I'm using git without my config and my muscle memory types one of my aliases, it's obvious what the verbose command I need to type is.
