Be careful! List of affected gear is below 👇

🚨 BREAKING: A Broadcom Wi-Fi bug lets anyone in range run code on routers without the password.

Quentin Kaiser showed it on Proximus, Orange Belgium and VOO routers and estimates ~1.5M in Belgium are exposed, none patched.

The bug dates to 2010. Broadcom won't assign a CVE.

@allegrajacchia @elonmusk Where to possibly get an invite?

Flying @Tesla Roadster is very impressive. The future will be very interesting!

In what ways did you leverage #SI tools in your everyday life as a network engineer? Share your ideas 👇

[WiFi Whiz @802doteleven]

+3 dB = double the power
−3 dB = half the power
+10 dB = 10x the power
−10 dB = 1/10 the power
I step the AP up 3 dB at a time, back down 3 dB at a time, then jump ±10 dB, against three walls:
- Drywall ~3 dB: most of the signal passes, about half is lost
- Concrete ~13 dB (10+3): only ~1/20 makes it through
- Metal ~30 dB (10+10+10): ~1/1000 gets through, the rest reflects back into the room
Notice that doubling power doesn't double coverage, and no amount of +3s gets you through a metal wall.

In all examples I account for a 1 dB cable loss.

Watch the rule of 3s and 10s play out in my RF lab 👇

@bressane @bot @bot now please reverse engineer the reverse engineered recipe for both Coca-Cola and Diet Coke, but don’t let anyone else have it

@bhunstable @HaydensCorner Let it sit for another year and see how far SI goes. It is very likely there will be a way. Just not yet.

@B_doong2daddy @tibor_tee @poteto Ask them to create you one

@_everythingism @AndrewCurran_ Do you think all indigenous Amazon tribes understand the chemistry behind the herbs they use to treat wounds? Yet they benefit from it because they know they work.

[WiFi Whiz @802doteleven]

Software reverse engineering trend is crazy.

[WiFi Whiz @802doteleven]

@AIandDesign I understand that the less mean data SI is trained on, the lower the chances it will be mean to humanity in the future. But what about the private chats?

@elonmusk @bot Hits weekly limit so fast though

If #SpaceXAI is renamed to #SpaceXSI, will the ticker be SXSI? 🤔
