fsckboy··on 1 kilobyte is precisely 1000 bytes?
musicians use numbering systems that are actually far more confused than anything discussed here. how many notes in an OCTave? "do re mi fa so la ti do" is eight, but that last do is part of the next octave, so an OCTave is 7 notes. (if we count transitions, same thing, starting at the first zero do, re is 1, ... again 7.

the same and even more confusion is engendered when talking about "fifths" etc.

fsckboy··on The next steps for Airbus' big bet on open rotor engines
>The cowling of the current turbines serves the same purpose, but needs to cover 360 degrees of rotation

this doesn't make sense. if you are not worried about fan blades flying off in directions other than the fuselage, why cover 360 degrees? (and if you are worried 360, then why open rotor?)

you can't invest in US equities without lots of exposure to the USD.

not investing in US equities would be... a strange investment strategy

exchange rates, interest rates: the best way to think of them is making all the other numbers balance. GDP, productivity, these sorts of things measure value creation. after all that is said and done, exchange and interest rates simply make sure the system balances out and bulgaria doesn't buy all the cars in the world by printing money. you're subject to them, but mostly you should ignore them.

fsckboy··on Nvidia shares are down after report that its OpenAI investment stalled
>It's roughly equal to giving 5% discount on hardware, not a big deal when the profit margin is 70%.

using your numbers, Nvidia didn't drop 70%, it's more on the order of the 5% so at least from that angle, the news narrative holds together superficially.

fsckboy··on Court orders restart of all US offshore wind power construction
the Venezuelan oil leases you are talking about was 1990s, not 1970s.

for Venezuelan oil leases to be comparable to wind farms you'd have to have the Venezuelan govt say "we are taking the leases away because we don't want any more offshore oil production", rather than "we are taking these leases away because you are rich and we want to pump the oil ourselves"

the cancelled Venezuelan oil leases were a taking, but that word is less useful in the case of wind farms. I would imagine firms with wind farm contracts would be made whole (i.e. get back lost investment, but not get back potential profit) but it's not a case of the wind farms being given to somebody else or those areas being put to some other use.

if you are "environmental" you might think it's a great loss not to pursue the wind approach, or that it's a great idea to shut down offshore drilling, but that's political not property ownership/taking.

fsckboy··on Building Your Own Efficient uint128 in C++
(I didn't read the article but the headline said "C++" and it did not say asm {...}, so here is a brief description of what's going on)

if you want to multiply two 8 bit numbers together, worst case (biggest numbers), you need 16 bits to hold the answer.

if you want to multiply two 16 bit numbers together, you need 32 bits to hold the answer. and so on, so you need a hardware wordsize twice as big as what you are trying to do.

if you don't have 64 bits, and you decide to use 32 to mimic it, well 32's require 64's to hold the answer and we just agreed you don't have 64s, so you need to go to 16 to catch the overflow into 32 so you can piecewise handle the 16 bit halves of the 32 to mimic the 64 you are trying to pretend you have. It's really just like gradeschool multiplication on paper where you piecewise multiply and add the different pieces together appropriately.

-----

"in hardware", like inside the CPU, you can handle calculations in exactly the space you have because you have extra bit flags like "overflow" OVR and you can do shifts to handle a bit at a time, etc. or even a ton of extra bits that add up to 128 even though the results will be in 64 bit registers. at the level of C and C++ you don't have the facilities for that (a glaring omission imho, but so called smart people are dedicated to taking C even farther from being useful for what it's useful for)

fsckboy··on My iPhone 16 Pro Max produces garbage output when running MLX LLMs
>Moon plus sun is a wildly more massive, nuclear furnace of a moon that also engulfs the earth.

i just looked up mass of sun vs mass of moon (they differ by 10^30 vs 10^20), and the elemental composition of the sun: the moon would entirely disappear into the insignificant digits of trace elements which are in the range of .01 % of the sun. I could be off by orders of magnitude all over the place and it would still disappear.

fsckboy··on Jack Kerouac's 37 metre-long, first draft scroll of On the Road to be auctioned
FTA: This scroll is one of the most important literary documents still in private hands.

and: However, the return of the scroll to the auction block echoes an earlier controversy. In 2001, when the manuscript was last offered for sale, Carolyn Cassady – the former wife of Neal Cassady, the real-life inspiration for the novel’s Dean Moriarty – denounced the auction as “blasphemy”, arguing that the scroll belonged in a public library rather than a private collection. “Jack loved public libraries,” she said at the time, adding: “If they auction it, anybody rich could buy it and keep it out of sight.”

what is/are the thread synchronization protocol called which is the equivalent to ethernet's CSMA? there's no "carrier sensing", but instead "who won or mistakes were made" sensing. or is that just considered a form of spinlock? (you're not waiting for a lock, you perform your operation then see if it worked; though you could make the operation be "acquire lock" in which case it's a spinlock)

according to urban dictionary, wolfenstein as a verb means

To kill or utterly destroy a large group of enemies with an extreme overabundance of weapons and items, including throwing knives to the head, poison, stabs to the neck or back, kicks to the chest, shoves off of high ledges, multiple headshots, artillery, panzer rockets, flames, dynamite, mines, construction pliers, airstrikes, or even slamming a door into someone's chest. Wolfensteining a group of enemies requires that every kill be performed using a different method

you are calling for extreme violence?

fsckboy··on France Aiming to Replace Zoom, Google Meet, Microsoft Teams, etc.
the Europeans have only ever purchased American products because they were cheaper by the feature, and there wasn't a political constituency to placate (see the [wine lake|wikipedia]). and the US in return.

as it was, so shall it always be.

any appetite to flush money down the drain because Greenland feels insulted will dull very very quickly. However as defense treaties have always been more fleeting than NATO has been, we can be sure the Europeans will quickly find better, more reliable partners than they've had in the US, no doubt at lower cost for all concerned.

fsckboy··on Find 'Abbey Road when type 'Beatles abbey rd': Fuzzy/Semantic search in Postgres
everything you are saying rings perfectly true to me but there's an additional problem I encounter. (i'm going to make up my example because i'm lazy to check but you'll get the idea) say you want to look up "Alexander the Great"...

...God help you if Brad Pitt and or the Jonas Brothers ever played a role with exactly that name-match. The web and search (and the culture?) have become super biased toward video especially commercial offerings, and the sorting ranked by popularity means pages and pages of virtually identical content about that which you are not interested in.

fsckboy··on The lost art of XML

yes, me too! when using XML it rendered all the flexability and power of the unix tools pretty useless, and I missed them.

>XML shall be straightforwardly usable over the Internet.

is machine to machine communication

to me, XML is an example of worse is better, or rather, better is worse. it would never have come out of Bell Labs in the early 70s. Neither would JSON for that matter.

fsckboy··on AI is a horse (2024)
>- You're not going to take an electric bike mountain biking

this sounds like a direct quote from Femke Van Den Driessche, who actually took an electric bike mountain biking: big mistake. Did it not perform well? no, actually it performed really well, the problem was, it got her banned from bike racing. Some of the evidence was her passing everybody else on the uphills; the other evidence was a motorized bike in her pit area.
