I’m often surprised how little people talk about the iOS Orion browser on here and it’s ability to let you use both Firefox and chrome extensions. I’ve been using it for a while now and it’s been great. It’s a little bit buggy sometimes, but nothing that would make me switch.


My dad was diagnosed with multiple myeloma 2 years ago. His bone marrow transplant failed (frequent first line of defense) and he just finished CAR-T therapy a couple months ago. The initial side effects from the treatment were _bad_, but everything is looking good right now. CAR-T is really mindbogglingly insane cyberpunk stuff.


I had a close relative diagnosed with multiple myeloma 25+ years ago (I don't remember the exact year) who only lived for a couple more years. It was rough back then. I'm really glad to hear that there is much better treatment these days.


can someone ELI5 how these proof-of-work captchas work under the hood to detect whether i'm a bot or not?


They don't detect if you're a bot or not; it just makes it more expensive, the idea being that doing $action 10,000 (or more) times becomes much more costly for the attacker, preferably to the point where doing $action (posting spam, creating accounts, etc.) is no longer profitable. It's probably more useful to see it as a ratelimiter than a bot detection mechanism.


Until, of course, the attackers reprogram their FPGAs and can solve challenges 10,000 times faster than a legitimate user. And since you can't request a user to have their phone toast itself at 100% load for 10 seconds, the attackers can solve it in micro/milliseconds for a sip of power.

Actually, this just uses SHA-256 hashing, which already has specialized CPU instructions (that browser WASM can't use) and ASICs.

I can't see how this isn't DOA?


They don't detect if you're a human exactly. What they do is they create a calculation expense that is negligible if there's one of you but adds up quickly if you're running a bot farm that needs to send out 10,000 requests a second.

So I click the button, my browser does a quick proof-of-work, no big deal.

But an automated script will have to complete that proof-of-work every time it encounters it, skyrocketing the cpu costs for the server.


They make it expensive to run large scale bots, so that deters the bots.

And they (probably?) use the computation power to crack passwords from people to let the government agencies access their accounts...


This could be incredibly useful for me. Currently struggling to complete jobs with massive amounts of shuffle with Spark on EMR (large joins yielding 150+ billion rows). We use Glue currently, but it has become cost prohibitive.


You should try using an S3 based shuffle plugin: https://github.com/IBM/spark-s3-shuffle

Then mount FSX for Lustre on all of your EMR nodes and have it write shuffle data there. It will massively improve performance and shuffle issues will disappear.

Is expensive though. But you can offset the cost now because you can run entirely Spot instances for your workers as if you lose a node there's no recomputation of the shuffle data.


Is the shuffle the biggest issue? Not too sure about joins but one of the datasets we're currently dealing with has a couple trillion rows. Would love to chat about this!


I think I'd need gemini 2.5 built into the trial to try this out. It's crazy how bad claude has become.


I thought the era of gratuitous cursing was behind us. Oh well.


frick no it's not




Curious on this: "Atuin's sync keeps my history on all of them"

I just checked on their GitHub and it says "Additionally, it provides optional and fully encrypted synchronisation of your history between machines, via an Atuin server."

So you trust all of your shell commands to be stored on a server that you don't control?

Maybe I'm missing something here.


Sync is optional*, end to end encrypted, and you can self host the server so you don't really need to trust anything if you don't want to

*: nothing syncs if you don't register, and you can even compile a version with the sync code flagged out if you REALLY don't want to trust anything


Got it, thx!


The Barnes Foundation is one of my favorite museums in the country. There isn’t anything else quite like it.


Is it still going? I watched "The Art of the Steal" documentary and thought it shut down.


The Art of the Steal was made in the middle of the controversy. They ended up moving everything to the city after all and it is alive and well
