    Do you or have you ever worked in science? I did for a bit and that was not my impression.

    I imagine it depends heavily on the field. In some fields there are ideas that one can’t seriously study because they’re considered settled or can’t be studied without doing more harm than any believed good that could be achieved. There are others subject to essentially ideological capture where the barrier to publish is largely determined by how ideologically aligned you are (fields linked to an identity group have a bad habit of being about activism first and accurate observation of reality second).



  • instead of blocking advertising data, we should embrace it IMO.

    imagine a world where users shove so much information at these tools that they can’t even tell what’s real or not. camouflage works better when everyone participates.

    There’s an ad blocker that does exactly this. Called Ad Nauseam. Chrome blocked it from their store super fast, then blocked it from being installed in Chrome from 3rd party sites, then blocked known versions of it from being manually installed in developer mode. I used to run it set to a low percentage - if I “clicked” every ad they’d know to throw my data out, but if I click say 3% of them…






  • With the introduction of protected mode it became possible for programs to run in isolated memory spaces where they are unable to impact other programs running on the same CPU. These programs were said to be running “in a jail” that limited their access to the rest of the computer. A software exploit that allowed a program running inside the “jail” to gain root access / run code outside of protected mode was a “jailbreak”.

    I still miss the narrow window in which you could make use of paging without technically being in protected mode. Basically there was like one revision of the 386 where you could set the paging bit but not protected mode and remain in real mode but with access to paging meaning you got access to paging without the additional processor overhead of protected mode. Not terribly useful since it was removed in short order, but neat to know about. Kinda like how there were a few instructions that had multiple opcodes and there was one commercially distributed assembler that used the alternative opcodes as a way to identify code assembled by it. Or POP CS - easily the most useless 80086 instruction, so useless that the opcode for it got repurposed in the next x86 processor.






  • You know that AR doesn’t stand for assault rifle, right? The AR is for Armalite, the inventors of the design. It’s just a semiautomatic rifle with a detachable magazine, it’s pretty common to use as a hunting rifle.

    And yeah, you see AR-15 and it’s workalikes all over the place because they’re flexible. Literally the most common rifle in the US. That’s why they’re so common in public mass shootings - those shooters generally aren’t buying a gun specifically for that sort of shooting, they’re using a gun they already have access to or what they can readily purchase off the shelf.

    It’s not the best gun for any scenario, but it’s a good enough gun for most and that’s because it’s modular and the guns and parts are both commonly available.
