    There is a dynamic API too that allows extensions to modify the blocklist at runtime. I’ve been using UBlock Origin Lite on my iPhone for a while, and that works great, keeping its…

    Not really... backdoor just means something that can bypass the main security. It's just that publicly known backdoors are of very limited usefulness, because people go out of thei…

    Comment #49220206

    "It's documented in the datasheet" is such a weak excuse for a backdoor. Documenting a backdoor doesn't make it not a backdoor, just means it's not a hidden backdoor. The fact that…

    The repo page says exactly why these long running instructions were researched. A very long-running instruction can be used to break SMI: https://github.com/xoreaxeaxeax/smiiiiiiii…

    It's actually benchmarking 1000 repetitions of the RDTSC instruction running in parallel. My guess... On Skylake, multiple in-flight RDTSC instructions slow each other down for som…

    As specified by the spec, it arguably increments RIP by one. The actual typical hardware implementation just fetches the next 16-32 bytes from icache, shifts it to the correct alig…

    Even if they need to replace every single lithography machine, there are a lot of other machines that probably don't need to be replaced for any given upgrade. Like everything rela…

    There is some overlap. The last DDR4 fabs were typically on a 16nm process, the first DDR5 fabs were also on a 16nm process. There shouldn't be much issue converting those 16nm DDR…

    > Before dynamic branch prediction... static branch prediction had been used for decades. I'm not sure that's true. At least not the "predict backwards branches are taken" part. Ma…

    I'm more thinking about how MIPS were quite late to branch predictors. They were shipping the high-performance R4000 and R4400 with 8 stage pipelines and no branch predictors. They…

    I think the Pentium is more or less the first microprocessor with branch prediction. Certainly the most mainstream. PowerPC 601 arrived at more or less the same time, and the Alpha…

    I think they are claiming it was the first merger of a multiple cities and a county. Rather than something that was originally created a merged county/city (like San Francisco) or …

    Yeah... I was worried that might be true.

    If you were limited to just a single frame of itra blocks, then yes. This would be an example of logic without storage. Also quite limiting as wires could never cross. But I was ki…

    I think you also need some form of intermediate storage to be Turing complete. Not that this example doesn't have intermediate storage... But I suspect you could create or discover…

    Really depends on what a hello world is meant to be a simplification of. If hello world is meant to be a simplification of printing large amounts of text to a buffered standard out…

    And the “electronic” part is important. The Z3 predates in by 2 years and was a programmable digital computer, except it used electromechanical relays. The Z3 is arguably more prog…

    I suspect it's possible to build an active radar without exceeding the limits of the ISM bands. Actually, I know it's possible, that's how the automotive radars (used for adaptive …

    Power consumption seems a bit high. Other than that, looks awesome. I checked, the 2nd gen iPod mini can get 18 hours of listening on a 400mAh battery, with a spinning HDD. This is…

    There isn't really a restriction that a downstream device will only have one mac address. It might be another switch. Even if it's not; VM/container networking is often implemented…

    You already need to add a decent quality DAC/Amp, might as well add a SD card slot at the same time. On top of the lower power consumption, another advantage of the pico is that yo…

    Or even the Pi Pico. You really don't need that much processing power to decode mp3s and FLACs.

    There are so many 3rd party parts available for iPods. Pry it open, replace the battery, swap the HDD for something like the iFlash.

    I guess there just is no room in the current market for a mid-ranged product. The segment is being squeezed on at least five sides (probably more): - Cheap low-end no-name players;…
