I don’t suppose I know someone who works at Tiktok security and can recover a hacked account for a friend?

I would like to compare with Claude and ask it the same deep technical security questions but it always replies with « I can’t help you do something potentially illegal or voiding your warrantyΒ Β».

I used Gemini 1.5 a few times and found it totally useless.

Today I got 2.0 and I was like « wow it’s actually greatΒ Β».

Then later I was like « Damn it’s still totally dumb sometimesΒ Β». Turns out it has reverted to 1.5.

So blind test confirms Gemini 2.0 is actually good.

I’m usually quickly disappointed by products I buy nowadays, but the OnlyCat is amazing. Changed my mom’s life.

Russian Spies Jumped From One Network to Another Via Wi-Fi in an Unprecedented Hack In a first, Russia's APT28 hacking group appears to have remotely breached the Wi-Fi of an espionage target by hijacking a laptop in another building across the street.

Russian spiesβ€”likely Russia's GRU intelligence agencyβ€”used a new trick to hack a victim in Washington, DC: They remotely infected another network in a building across the street, hijacked a laptop there, then breached the target organization via its Wifi. www.wired.com/story/russia...

Basebands are notoriously programmed to cooperate nicely (with other devices, towers, etc). They are not meant to work in adversarial conditions.

I did a study once and I found one single defense company that sold a military smartphone with a proprietary baseband allegedly.

Is it me or companies who develop β€œmilitary grade” smartphones (with the actual goal of selling to the military) with a custom OS on a mostly COTS phone with a standard baseband with the manufacturer’s firmware are pretty much selling snake oil?

So if I were to want to fine tune an LLM on a 4090 to a specific knowledge domain, what model should I start with today? Or are there better solutions?(e.g. renting cloud A100)

Schaden von bis zu 30 Millionen Euro: Berliner Carsharing-Anbieter Miles soll bei Parkgebühren in g... Beim grâßten Sharing-Anbieter der Hauptstadt gab es am Mittwoch Durchsuchungen. Wurden Daten parkender Fahrzeuge manipuliert, um Gebühren zu umgehen?

Interesting news from the world of carsharing: the biggest player on the EU market, Miles, is under criminal investigation, as they wrote some hacky code that modified (!) GPS data in the cars, resulting in 30-50 M€ in unpaid parking fees.

This is huge: 1/n

Continuosly baffled by Bluesky's lack of improvements:
- Invite only, still.
- Can't see content if not logged in.
- Can't upload gifs, videos or sounds.
- No DMs.
- Mobile app restarts everytime you switch apps.
- Logo/Banner looks like a placeholder.
- Loading times are slow.
- Can't see trends.

GitHub - jrozner/msp430-testbench: Tools for testing behavior of msp430 instructions Tools for testing behavior of msp430 instructions. Contribute to jrozner/msp430-testbench development by creating an account on GitHub.

It's nothing crazy but I finally documented and released the tooling I created for inspecting the instruction behavior while building the lifter for my Binary Ninja plugin https://github.com/jrozner/msp430-testbench . Maybe this approach will be helpful for other embedded architectures for others?
