I donโ€™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 ยซย I canโ€™t help you do something potentially illegal or voiding your warrantyย ยป.

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

Today I got 2.0 and I was like ยซย wow itโ€™s actually greatย ยป.

Then later I was like ยซย Damn itโ€™s still totally dumb sometimesย ยป. Turns out it has reverted to 1.5.

So blind test confirms Gemini 2.0 is actually good.

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 spiesโ€”likely Russia's GRU intelligence agencyโ€”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 โ€œmilitary gradeโ€ 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 manufacturerโ€™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)

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 Mโ‚ฌ 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?
