    Oh absolutely. I agree. I don’t think anyone’s disputing that something about it needs to change. Even given that things cost money to run, for profit journals that can basically act as gatekeepers means there’s also going to be excessive price gouging and profiteering and that needs to change.

    Surely there has to be a cost to the infrastructure of publishing and curation though. And possibly all the work of setting up and organizing the peer review process. So they probably charge the institutions or authors submitting the paper instead of their readers. But perhaps we should treat scientific journals as a public good, like libraries, or at least have a publicly funded option. Or have universities and institutions fund it for the public good.


  • Maybe, but Microsoft’s competitors are doing a lot better on the battery life front so they’re leaving a lot on the table for competitors to swoop in by not fixing their sleep and wake issues. It was a big consideration for the company I work at to go with Apple machines because they do lots of field work and need the machines running all day. I can say from experience it’s incredibly frustrating to leave home with my MS Surface on a full charge only for it to have majority of the battery drained by the time I pull it out of my backpack due to waking up when it wasn’t supposed to.

    Idk man I’ve seen mathematicians at my university shudder at applied math and they were kind of half joking and half not. Not all of the faculty were like that though, some of them had a wide range of interests! My favourite was a wonderful Polish professor named Edward who knew tons of things about not just math but also computer science, physics, and chemistry.



  • It will prefetch the instructions and put into the pipeline the branch it thinks is mostly likely. It may do ahead-of-time speculative execution on certain instructions but not always. If it missed the correct branch it will flush the pipeline and start the pipeline over again from the correct branch. Afaik it doesn’t execute or prefetch both branches. The other guy is saying it does but that doesn’t really gel with my own recollection or the Wikipedia article he cited. You can see some further discussion that suggests only one branch gets prefetched here here and here. Reasons cited for only predicting one branch are: 1) Two pipelines with all the associated circuitry to look ahead, decode, and speculatively execute is incredibly expensive in terms of both processing requirements and die real estate. 2) Caching both would thrash your caches with new data constantly. 3) Modern branch prediction is already so accurate, there’s really no need for two pipelines anyways.
