  • It’s not reading the contents of RAM via EM emanations, it’s using the EM emanations caused by certain memory access patterns as a side channel to exfiltrate data. Of course, that data could be anything, including whatever is in RAM, but the point is that you need to be running the code that generates the necessary memory access patterns to transmit the bits of data. This is not like TEMPEST where you can reconstruct a video display just using the emanations.




  • He doesn’t actually do the calculation required to give an estimate of what that number is.

    Going on the stats in the article:

    • assuming that Wukong has just surpassed the revenue of Steam Deck in the chart so we can treat their revenues as equal
    • assuming Wukong price is $49.99 and average Steam Deck price is $500
    • using the stat that 14m copies of Wukong sold on Steam so far

    that would imply ~1.4m Steam Decks sold

    The article does go on to say:

    Keep in mind that by November last year, Valve said the Steam Deck had already sold “multiple millions”.

    So really this (very rough estimate) is telling us nothing that we didn’t know already. The top seller charts are showing exactly what we would have expected to see.






    • 218/250 were fully playable at good framerates (60+). He notes that the more popular a game is the more likely it is to work flawlessly.

    • Of the remaining 32 games that had problems, 12 of them defaulted to the iGPU on the CPU instead of using the Intel dGPU. He had to disable the iGPU in Device Manager to get them to use the dGPU. 11 of those 12 worked flawlessly after making this change.

    • 5 games crashed on launch (Avatar: FOP, Batman Arkham Knight, Sim City 4, Left 4 Dead 2, Saints Row 2)

    • 6 games ran but with graphical artifacts (Bioshock, Dirt Rally, Ghost of Tsushima, Starfield, GTA4, The Witcher 3)

    • 11 games ran but with poor performance (Starfield, Alan Wake 2, TLOU1, Hellblade 2, Dragon’s Dogma 2, Yakuza Like a Dragon, Metro: Last Light, +4 more not specified).

    • He also had problems running with multiple monitors.

    • Older games seem to mostly run fine, newer games seem to be the ones more likely to have problems.






  • I lost my earbuds in a remote town in Chile, so tried buying a new pair at the airport before flying out.

    True Apple lightning devices are more expensive to make.

    I wish @Apple would devote an employee or two to cracking down on such a technological, psychological abomination as this.

    He wants to take away a budget option from developing countries where people can’t afford the expensive version of the proprietary technology, and he wants Apple to be the one to do it?

    Fuck this guy.
