UnDOS'ed: Not to brag but, after 3 months I finally convinced @signalapp to upgrade their entire job queue infra to a far richer one that not only won't result in a CVSS 8-10 DOS for users anymore but also became a permanent new background feature called Chat Refresh that prevents those same deadlock conditions for all users. No thank you mention in app or bug bounty paid just a generic thank you email but still glad I put in the debug effort.
Operations are now batched in independent queues instead of blocking each other through one write lock. This wasn't just a patch on the delete timeout. They had no choice but to rebuild the entire sync infra with manifest reconciliation and separate queues. All 3 of my recommendations were adopted, chunked execution with yield, state reconciliation and defensive sync. A full arch restructuring is rare from a bug report.
Most of you won't notice the decomposed monolithic sync but after watching 1000 old messages sync fast without a hitch i'm proud of myself and their dev team (despite the understandable delay). I don't think any other app has that or comes close now. And who knows how it could have been weaponized to lock users out.
To 50-80 million users, you're welcome.
A message to every founder & braindead VC:
Anyone who thinks protection is a red flag is a predator looking for easy prey.
Green flags look red to thieves.
@nic_detommaso It will happen but, it will take a few decades at least.
It's basically life, with a timer.
We should all just get used to living inside of a ticking time bomb. #Y2K
I wonder what percentage of those 8k sellers comprises amazon brand products now. It's the supermarket model all over again and reminds of me the same market concentration trend in depleting public companies. Since the 90's peak we've declined by half and it's persisting in 2026. 8k to under 4k or about 200 per year vs 400 in the 90's.
The median age of a company at IPO has tripled from 4 to 12 years but the market itself remains robust due to massive growth in private market assets, projected to reach 66 trillion by 2033. The Wilshire 5000 Index reveals this patently as it only includes about 3500 companies now despite the name. VC / PE is driving it but on the flip side it's also partly from hostile litigation environments (thus Delaware's popularity) and compliance burdens.
@NateMatherson most people rolled back to 4.6 immediately. 4.7 is a breaking change experimental model technically, avoid. It's lack of temperature alone is why it's replying that way!
@neuralunlock We're hiding from you bastards! VC's will be dinosaurs.
weird that I see another comment about dinosaurs after typing that.. consider that a sign.
