does anyone have wifi disconnect all the time on the iPhone/iOS 27? been happening since Dev Betas and seems to still happen all the time for me at home.
html5cat··on Ask HN: Who is hiring? (September 2026)
thanks Gmail for Google Workspace for pulling Brian's threads when searched for `boltzmann-brain`.

but yeah, if you bump the thread with `html5cat` mentioned i'll personally look into it – my goal is to respond to every earnestly submitted application despite the sea of AI slop.

update: found your email – definitely well written but didn't have GitHub so it got skipped.

html5cat··on Ask HN: Who is hiring? (September 2026)
Which of these two are not generic? There's dozens you spammed us and other startup founders with. Some are just empty emails with just CV. None were sent in Feb fyi.

"I have attached my resume in response to your posting. I am interested in interviewing ASAP."

"Good afternoon, I saw your post on HackerNews and I am interested in interviewing. Best, Brian"

html5cat··on Ask HN: Who is hiring? (September 2026)
try counting how many "I"/"my" you have even in just this comment compared to "team" or "Puma" or "users/customers".

instead of bumping the email thread you decide to put this all publicly. ok. but if you want to be pedantic, our HN post includes "what you'd like to build next?" which you conveniently skipped.

if you read our website, the application there includes "Why I’m interested to join Puma?".

you seem to care much more about being right than making progress or being helpful. i hope you change your approach since you clearly can build things.

html5cat··on Ask HN: Who is hiring? (September 2026)
found your thread – your email covers things you did, but nothing about "why Puma" or other simple questions we ask. seems like one sided, generic mass application. impressive background, but didn't seem like you care about what we're building.
html5cat··on Ask HN: Who is hiring? (September 2026)
your first two application were generic and ignored the few basic questions that we ask in the posting, thus subsequent one didn't get reviewed
html5cat··on Ask HN: Who is hiring? (September 2026)
apologies, we've got a lot of ai-generated applications in the last few months so might have missed it. mind bumping the thread and mention `html5cat` and i'll make sure we look into it?

thank you!

html5cat··on Quake – 30th Anniversary Update
it is free though, no? am i missing something?
html5cat··on Quake – 30th Anniversary Update
If i understand correctly Bethesda has the original IP and would just need a regular apple dev account if they wanted to publish, no?
html5cat··on Quake – 30th Anniversary Update
Surprised they didn't port these to Mac yet. Between M series and Game Porting Toolkit (4 now?) it seems like small effort can unlock huge wave of new players nostalgic for childhood game.
html5cat··on Apple sues OpenAI, accuses ex-employees of stealing trade secrets
Interesting how Tang Yew Tan worked at Apple for 25 years (!!) and then threw it all out for this.

html5cat··on Qwen 3.6 27B is the sweet spot for local development
Awesome idea! Will try it out. Wish there was a way to enable low power on a per-app basis. Scrolling and reading on low power mode is really annoying.

OpenRA is amazing. Sort of related, recently discovered a great remake of Heroes of Might and Magic II:

You, sir, are a fish. Good luck on the path!
html5cat··on Kindle loyalists scramble as Amazon turns page on old e-readers
Maybe it's ok to upgrade an o($100) device once after, checks notes, 14 years? Incredible longevity compared to any other device
html5cat··on Googlebook
Original Pixelbook was amazing and my fam still uses it. Wish they just stuck to the lineup and kept iterating vs giving up and trying to rebrand every few years.
html5cat··on Integrated by Design
Unrelated to the article, the game on the website is very addictive )) Had to get to the top of the leaderboard.
html5cat··on Filing the corners off my MacBooks
funny how this is actually the default for me having grown up in Ukraine.

probably same for other post-soviet countries too?

html5cat··on Filing the corners off my MacBooks
Not all heroes wear capes. This is excellent and can't wait to get aluminium mac next to try it – don't think Space Black is a good way to go.

Author's another post on "The Seasons are Wrong" [0] is excellent too and I fully support both approaches.
