jcmfernandes··on Starlark Programming Language
This is also one of my major complaints at this point. I'm building a developer tool with starklark resting at its core and I had already came across your work.

I wish the starklark team had addressed it at this point.

Wat?

jcmfernandes··on OpenID Connect specifications published as ISO standards
There are LOTS of them. Anything that allows you to link your Google/Facebook/etc. account to another system, so that system can perform actions on your Google/Facebook/etc. account on your behalf.

Examples: Slack (e.g., notify you of events on your calendar, create a GMeets meeting), services like cal.com, whatsapp (store backups on your Google Drive).

jcmfernandes··on OpenID Connect specifications published as ISO standards
Since OIDC is a layer on top of OAuth 2, it inherits its complexity. OAuth 2.1 (currently draft) will help bring some sanity. GNAP - https://oauth.net/gnap/ - will, one day, tie everything.
jcmfernandes··on OpenID Connect specifications published as ISO standards
Correct. OAuth is for delegated authorization. OpenID Connect for authentication.
jcmfernandes··on Ask HN: What Are You Working On? (October 2024)
Busy market, hard to sell to companies who need to migrate. The main reason for migrations is price (eg. Auth0 being super expensive), which is not a good thing. I'm probably not telling you anything new.
jcmfernandes··on Portugal seeks to become low-tax haven for young people
It can go up to 48%. But as in most countries, it's progressive: you pay X% over the first A€, then Y% over the next B€, etc.

Then you have Social Security (mandatory): 11% on the employee and 23,75% on the employer, or 21,4% for independent workers.

jcmfernandes··on Portugal seeks to become low-tax haven for young people
Portugal already has tax breaks for the youth (aka IRS Jovem), but the new right-wing government is seeking to extend what the previous left-wing government introduced. That includes loosening requirements and extending the duration of the tax breaks.

Now, while in Portugal people talk about these as measures to retain the Portuguese youth in the country, no political party has framed it as a measure to capture foreign youth. Puzzling to me.

jcmfernandes··on Ask HN: Platform for 11 year old to create video games?
https://github.com/hajimehoshi/ebiten (golang) and https://github.com/gosu/gosu a (ruby) are, IMHO, worth exploring if you want to put some emphasis on coding.
jcmfernandes··on Show HN: Io_uring for Ruby
I expected this comment, just not so early in the life of this thread. Moving on... cool stuff!
jcmfernandes··on Boxxy puts bad Linux applications in a box with only their files
I'm sorry to hear that. Thanks for the tool and wishing you a speedy recovery!
jcmfernandes··on Designing my own watch (2020)
There's a Portuguese watch company using this same style since 2016: https://isotopewatches.com/products/isotope-gmt-zero-degrees

I love their timepieces.

Do they use zeitwerk?
jcmfernandes··on Stripe's Monorepo Developer Environment
Thanks for this. Can you share the experience of those who don't use VS Code?
jcmfernandes··on A Gentle Introduction to SAML
OIDC standardadized Initiating Login from a Third Party: https://openid.net/specs/openid-connect-core-1_0.html#ThirdP...

It works very differently, but it will get the job done in a much safer way.

jcmfernandes··on A Gentle Introduction to SAML
Here's an interesting blog post on why SAML is insecure by design: https://joonas.fi/2021/08/saml-is-insecure-by-design/

Malleability sucks in this context.

jcmfernandes··on A Gentle Introduction to SAML
OIDC supports Initiating Login from a Third Party: https://openid.net/specs/openid-connect-core-1_0.html#ThirdP...

Unlike SAML's "take this assertion" IdP-initiated flow, OIDC went for a "start an authentication with this IdP, for this user, and send them back here". Much, much safer.
