i didn’t downvote you, and i went to school before a bunch of things but technology evolves and either we evolve with it or we end up being just straight up wrong in a modern context

not exactly because of pairs unless you’re talking about 1 and 0 being a pair… it’s because the maximum number you can count in binary doubles with each additional bit you add:
with 1 bit, you can either have 0 or 1… which is, unsurprisingly perhaps, 0 and 1 respectively - 2 numbers
with 2 bits you can have 00, 01, 10, 11… which is 0, 1, 2, 3 - 4 numbers
with 3 bits you can have 000, 001, 010, 011, 100, 101, 110, 111… which is 0 to 7- 8 numbers
so you see the pattern: add a bit, double the number you can count to… this is the “2 to the power of” that you might see: with 8 bits (a byte) you can count from 0 to 255 - that’s 2 (because binary has 2 possible states per digit) to the power of 8 (because 8 digits); 8^2
the same is true of decimal, but instead of to the 2 to the power, it’s 10 to the power: with each additional digit, you can count 10 x as many numbers - 0-9 for 1 digit, 00-99 for 2 digits, 000-999 for 3 digits - 10^1, 10^2, 10^3 respectively
and that’s the reason we use hexadecimal sometimes too! we group bits into groups of 8 and call it a byte… hexadecimal is base 16, so nicely lets us represent a byte with just 2 characters - 16^2 = 256 = 2^8
which is why we have kibi, mebi, gibi, etc

Technology@lemmy.world•Why a kilobyte is 1000 and not 1024 bytes
1512·2 years agokilobyte (KB) is 1000, kibibyte (KiB) is 1024
at least according the the IEC, and id tend to go with them… SI units say that kilo means 1000

Selfhosted@lemmy.world•Can I build a NAS out of a desktop? [Request]
3·2 years agokinda the same reason people suggest something like linux mint over slackware, gentoo, arch, etc… mint is easy to install and is preconfigured to be an easy to use user desktop environment. you can configure any other option to be have like that, but they tend to be a bit more “DIY”, which is great if you know what you’re doing!
dedicated NAS OSes will have good software out of the box that make it easy to configure and manage various common disk-related configurations (RAID, SMB, NFS, etc). you can certainly do all this yourself, but it might not have a pretty, unified user interface, or you might have to deal with software that isn’t compatible with some version of a library that’s in your distro of choice… all resolvable things, but they take time to solve: anywhere from installing a package manually to applying a kernel patch and recompiling the kernel to get something to work

5·2 years agoi’d avoid BIOS-based RAID… it doesn’t really offer many benefits over linux-based raid like MDADM, and MDADM offers a LOT of up-sides for portability, repairability, diagnostics, etc

Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ@lemmy.dbzer0.com•I absolutely love VideoLAN's stance regarding patents

Ask Lemmy@lemmy.world•what if an anarchist group suddenly went to an island with no rules, law, government, etc??
1·2 years agoi’d say that we need a way of communicating and making group decisions, but government is an organisation that makes the decisions of the group… a government isn’t a process; a government is an entity… if your group decision making is a process rather than delegated power, then you don’t have a government but you may be able to effectively run your society
a healthy democracy requires others to have privacy. people like investigative journalists need to be able to blend in with the crowd and expose government wrongdoing
blending in the the crowd is the important part: if everyone cares about privacy, nobody sticks out for caring about privacy… but if nobody cares about privacy, the investigative journalist suddenly looks really obvious and can be targeted much more easily
if someone doesn’t think they have anything to hide, that’s fine (wrong, but fine) however they can help to make sure the government acts appropriately simply by not splashing data around everywhere for all to see

Ask Lemmy@lemmy.world•How will we ever get away from plastics when they are ubiquitous for safety
3·2 years agoof course, but they are complex problems and you shouldn’t poo poo a potential mitigation to 1 because it negatively impacts another
the solutions to complex problems shouldn’t require being solutions to every complex problem

Ask Lemmy@lemmy.world•How will we ever get away from plastics when they are ubiquitous for safety
22·2 years agothe plastic problem is separate from the carbon problem though… we don’t ban plastics because we’re concerned about climate change; we ban them because we are worried that microplastics are causing significant health effects to both humans and most other animals

Privacy@lemmy.ml•Do I need to be a resident of the EU to get their data protection or can I just be a citizen?
9·2 years agoonly sort of correct: the GDPR applies globally (see this comment: https://jlai.lu/comment/4089576), however if you don’t ever plan on visiting or doing business in the EU it’s probably one of those things that people would ignore because it’d be too difficult/impossible for the EU to actually follow up on

1·2 years agoafaik activitypub/fediverse doesn’t have to be fully open… there’s private messages and followers only profiles on mastodon… sure, any server admins of your followed would be able to see anything you post (and thus in this case for threads for example, if you accept any follower from threads then meta can see your stuff) but this also doesn’t grant them a license to use the content
also, bluesky will eventually be the same: it only doesn’t have those issues now because they haven’t opened up their software… it’ll have federation in the future, which means it has to be somewhat programmatically open to others

5·2 years agoamericans use “liberal” to only mean socially liberal, however liberal describes both economic and social philosophies
Liberalism is a political and moral philosophy based on the rights of the individual, liberty, consent of the governed, political equality, right to private property and equality before the law.
— https://en.m.wikipedia.org/wiki/Liberalism
economic liberals are all about the free market, social liberals are all about human and civil rights (among many other things)

you have FPTP; you do not have STV or RCV etc
i believe the general attitude on the threadiverse is that down votes are not a great option: they should represent low quality or untruth rather than simply dislike. given this preference, and downvote to hide might overload the downvote function: no longer is it a last resort, but it’s a normal part of browsing your feed. i’ve seen nothing but staunch opposition to overusing h the down vote feature in this manner
