@IceSolst Absolute gold!

Holy fuck really

[⁵⁄₉ @fiveoutofnine]

So basically, today PHP got two critical bugs that let anyone run code on your server without even logging in, which is bad, and then the details leaked before the patch was even out, which is worse, and it works on WordPress and MediaWiki and Magento and Joomla and Laravel, and Censys says like 1.5 million servers are running a version with no fix, so the NSA was like "take your system offline," and the FBI was like "take your system offline," and CISA and the UK and CERT-EU were all like "take your system offline," and then the Prime Minister of Japan, the actual Prime Minister, posted at 5:55 in the morning telling 48.8 million people to take their system offline, so everyone took their system offline, like the Dutch cybersecurity agency took its own website offline, and the Dutch parliament went offline, and the Port of Rotterdam went offline, and Finland and France and Denmark started pulling government sites, and Wikipedia went down, and https://t.co/QlOXb3COq3 went down, and Asana and GOG and Something Awful went down, and the University of Vienna's webmail went down for some reason, and that's just PHP. Because GitLab also dropped a CVSS 10.0, which is the highest score they give out, for a bug that's been there since 2014, so that's every self-hosted GitLab for twelve years, and then LiteLLM 1.107.0 got hijacked and shipped a credential stealer and a remote access trojan in every single wheel and the Docker images, including latest, and you didn't even have to import it, just installing it was enough, and it's the second time this year, and then Railway paused every deployment on the entire platform because someone got into the environment variables, so now everyone has to rotate every secret they've ever stored there, and TiDB Cloud said someone was walking around inside with stolen credentials for basically a month and an extortion group says they took 10.6 terabytes, and Zeabur got breached for the second time in two months and is just shutting down, like the whole company, and Node.js patched remote code execution and a TLS bypass, and CISA says Plex is being actively exploited, and someone took over 300 Tor exit relays to steal SSH passwords, and SafePay ransomware has hit over 600 critical infrastructure orgs, and India's biggest bank filed a data loss incident, and Japan has been in an official state of emergency in cyberspace since October 9, which honestly explains the 5:55 AM post. Oh, and eMudhra, a certificate authority that's issued over 60 million certificates, whose entire job is proving websites are who they say they are, was supposed to be using private keys that are random numbers over a hundred digits long, and one of them was 4. Just 4. And the others were like 66 and 237. Anyway, it's Wednesday.

now we are talking!

[Tibo @thsottiaux]

Day 16/

You can now cache for 12h in the API and for logged in users across Codex & Work we keep cache forever and you don’t have any penalty for coming back to an old conversation or resuming after a few hours and are now guaranteed to hit the cache.

[Ivan Oparin @ivanopcode]

@kabamdork @dexhorthy @zachlloydtweets Yeah, exactly this. SI is not one big model but a collective, a colony, a hive mind. Software factories are the anthills!

[Ivan Oparin @ivanopcode]

The 2008–2012 era gave birth to an unprecedented level of creativity. Most features shown on stage over the past decade were born back then as a @Cydia tweak. iOS sucks because creativity doesn't flourish in a walled garden. The only path for Apple is to open the system.

@viticci @johnvoorhees @badlogicgames One week and you've beaten Federighi's team to it!

[Ivan Oparin @ivanopcode]

worst timing ever!

[Porsche @Porsche]

Mission S.

Authentic. Consistent. Timeless.

A glimpse into the future - shaped by our heritage. Mid-engine architecture. A focus on the driver and the driving experience.

Call it a love letter.

[Ivan Oparin @ivanopcode]

Freaking insane.

[Collin Rugg @CollinRugg]

JUST IN: Elon Musk unveils the Tesla Roadster by launching it off a ramp before the car flipped in midair and safely landed on the ground.

The car is a collaboration between Tesla and SpaceX.

One of the most insane things I've ever seen.

[Ivan Oparin @ivanopcode]

@DanFessler Yay! 🙌

[Ivan Oparin @ivanopcode]

I think the same applies to hard architecture problems. Models don’t have taste and often can’t design an elegant architecture - I mean platform-level, how the pieces fit together. They produce something that works. To make it beautiful, with few parts and obvious boundaries, you need human × agent collaboration.

[Ivan Oparin @ivanopcode]

Couldn't agree more, codex is just complete outright ux mess, period.

[Ben Davis @davis7]

Went back to codex desktop today to do some tax prep stuff and holy hell the ChatGPT desktop app is falling apart

There's so much here I like and want to use, but it's such a slow, janky, incoherent mess it's impossible

The new "spaces" feature is actually amazing. Such a good idea that I've been building a lot of my video pipelines around, the only problem is that buggy and the UX is a dumpster fire

It seriously feels like there are 5 companies all working on their own products who have to ship them all together in the chatgpt desktop app while not being allowed to talk to each other

Go back and look at Dev day, they shipped 30+ features. Almost all of these are dope and useful. The problem is you haven't heard of 80% of them and it's all just floating around in this blob that's chatgpt

This stuff is hard, I don't envy the position they're in. You have to keep shipping as fast as possible so you don't fall behind, but you also need time to polish and organize things. And this has to be coordinated across a bunch of teams and dozens of people and hundreds (thousands) of agents.

I could go through all the specific issues but 1) it'd take too long and 2) anyone who uses it already knows most of these (very laggy, sidebar sucks, features are too hidden, spaces "tabs" system is a mess, etc.)

Codex desperately needs a dictator with an actual coherent vision

[Ivan Oparin @ivanopcode]

@ricketson_ Really cool stuff!

[Ivan Oparin @ivanopcode]

@johnternus @finkd @johnternus @finkd Amazing times! Thanks for bringing affordable compute to the people [and standing with your words]!

[Ivan Oparin @ivanopcode]

@DanFessler Word of a man!

[Ivan Oparin @ivanopcode]

@_ARahim_ Great work on fixing broken stuff!

[Ivan Oparin @ivanopcode]

💎 Another gem out there! I am running out of time to test all the amazing new stuff that improves my daily life on desktop!!!

[Abdur Rahim @_ARahim_]

You asked, so here it is: DigUp is coming to Windows and Linux 👀

Dropping in a few hours...

Mind-blowing. Next-level 'pelican riding a bicycle' result.

[fofr @fofrAI]

Argon has this amazing natural understanding of the world. It can do so many things from first principles.

Here's a pelican riding a bike, using fourier epicycles.

2/2: I open Claude before bed to check something personal and get an infinite list of agent sessions tirelessly building my product. Last thing I want to see at night. The chat I need is impossible to find, and when I do know where it is, the navigation is the worst possible. @claudeai do a better job!

[Ivan Oparin @ivanopcode]

1/2: I thought UI harnesses couldn’t be worse than the Codex mac app, but then I opened the new Claude on iOS. Next-level insanity. This chat/work unification is a disaster worth studying 🧵
