<UmbralRaptor>
(via @bofh)
<Iskierka>
wait, what?
<bofh>
UmbralRaptor: hey it's just one step closer to The Semiconductor Company
<Iskierka>
though they aim it at gamers and integrated stuff is no matter what still not good enough for anyone taking that seriously
<UmbralRaptor>
bofh: I'm missing context.
<Iskierka>
my laptop has 7th gen i5 and the integrated graphics is still not suitable even for stellaris
<Iskierka>
(the dedicated is and takes up much more space than the RAM)
<kmath>
<oshepherd> The year is 2025. All chips are made by Semiconductors Inc. https://t.co/7GuvnBkfI8
<rqou>
nah, i think there will be two
<rqou>
the english/western semiconductor company, and the CN semiconductor company
<UmbralRaptor>
Sort of like how there are so few aerospace companies?
<bofh>
So basically, Semiconductors, Inc and Intel?
<rqou>
sure
<rqou>
or maybe Foxconn and Intel?
<Iskierka>
what takes more capital to break into; aerospace, or silicon?
<rqou>
hopefully the "rogue province" gets reabsorbed by 2025 :P :P
<bofh>
rqou: I have close friends from there that would have a great deal of objections to that statement :P :P
<rqou>
for bonus fun, Foxconn is a taiwanese company
<Iskierka>
if this is the rogue province I'm thinking of they make my very nice pens. plz don't kill
<rqou>
fine, we'll be twisted and move your pen factory to Kinmen island :P
<rqou>
(which is also a fun geographical feature)
<bofh>
Iskierka: depends, fabless? aerospace, easily. fabbed? depends on how small of a process you want. up to ~45nm gate widths, probably still aerospace. Once you get to EUV photolithography and accouting for quantum tunnelling effects in the mask layer? it's... a tough call and I'm pretty sure at some point it switches to silicon.
<Fiora>
Aerospace is much easier to get into silicon. If you mean fabs.
<bofh>
LOL
<Iskierka>
ninja'd with a much bigger message
<Fiora>
You can design and launch a rocket for $5b. You definitely can't build a 10nm fab for $5b.
<rqou>
meanwhile a bunch of us still have a (vaporware) project to build a 10um/5um fab in a garage
<Fiora>
also because aerospace can be done with less institutional knowledge, AFAIK
<Iskierka>
too bad intel is in canada so are unlikely to have their fab facilities declared a public service and equal-access?
<Fiora>
that is, if you sum up the minimum number of people worth of knowledge to build a fab, vs to build a rocket
<Fiora>
it's probably much higher.
<bofh>
Yeah, that is true. Aerospace knowledge is *largely* public, pretty much everything you need is either on NTRS or in a Soviet journal somewhere.
<bofh>
and it's also *comparatively* simple physics-wise.
<Iskierka>
that I feel might depend on your definitions, aerospace I feel might take more people, but probably more people who have knowledge overlap, and are just needed for parallel work-hours
<Fiora>
You also don't need ~5nm precision on literally every single object in your building.
<bofh>
Fiora: agreed 100%
<Fiora>
Iskierka: I know a *single person* who has singlehandedly designed her own scramjet and has a fairly well thought out rocket startup plan (which necessarily includes other off the shelf components, etc)
<Fiora>
And what she has is *way more thought out* than actual real rocket startups that have gotten real funding in the $100s of millions
<Fiora>
and which imploded because their entire concept was doomed from the start as impossible.
<rqou>
for fab, you don't have to immediately jump to a 10nm fab; there's probably enough information out there to build a "usable" 500nm fab
<rqou>
of course, this won't really make any money
<Fiora>
same with rockets! you can start with model rocket kits.
<Fiora>
:P
<rqou>
true
<bofh>
...I never thought of the comparison being at that level, but... yeah, that's a good point.
<Fiora>
aerospace is actually in a weird place atm because again, well, you can get funded on basically nothing
<Fiora>
there are real rocket startups getting money for Absolute Garbage
<rqou>
i guess i just don't know anything about aerospace
<Fiora>
whereas there are definitely no fab startups (as far as I know) getting $100s of millions for stuff that will never work
<Iskierka>
I'm thinking for actually managing to end up doing something, not just getting startup cash
<Iskierka>
as the people providing that seem really dumb in general
<Iskierka>
you could probably con them just as hard with fabbing
<Fiora>
in this case iirc they literally didn't do the math on the energy storage/delivery necessary
<rqou>
who is giving out all this money? the same idiot VCs that fund IoT juicers?
<Iskierka>
I had an argument with someone on the KSP forum about escape dynamics. They were also doing maths wrong as well as being rather unrealistic about the effect of a 1% inefficiency in that much heating on the airframe
<Iskierka>
they now are sometimes an adviser for the interstellar mod
<Iskierka>
(I don't use that mod any more)
<Fiora>
rqou: there was a thread the other day on HN apparently where someone posted something along the lines of
<Fiora>
need help with a startup idea. we have multiple VCs willing to throw money at us but we don't know what to make. help please?
<bofh>
WHAT
<Fiora>
I wish this was a joke.
<rqou>
wtf
<Fiora>
are you really that surprised ??? VCs basically give money to people, not ideas
<Iskierka>
which is why I've not made any effort to look for an idea
<Fiora>
that's the entire premise of ycombinator, even
<bofh>
Fiora: so basically VC culture is the biggest old boys' nepotism club in Cali?
<bofh>
(except maybe second to politics and Holloywood?)
<bofh>
Hollywood*
<rqou>
now why can't someone give me free money? :P
<Fiora>
Yes, actually. Possibly worse
<Fiora>
Difference is, hollywood and politics are honest about it :P
<Iskierka>
I mean the VCs are pretty blatant about it if you just *look*
<rqou>
"my startup idea is to just take the money invested and invest it in an index fund while i sit around doing nothing. gib money pl0x"
<Iskierka>
I once saw a four-minute ad for that I *think* was a bicycle GPS ... with no screen. It just had LEDs that blinked to point left and right. And for that entire four minutes, NO-ONE ACTUALLY CLARIFIED THIS
<rqou>
i bet this would actually be a better business model than some startups
<Fiora>
rqou: so there's one more part missing
<Iskierka>
there was maybe 30 seconds of shots of a prototype on a bike, and nearly four minutes of talking heads about their *vision* to improve cycling
<Fiora>
many startups have horrible ideas or none at all, and yet, they still make VCs money
<Fiora>
because of greater fool theory
<Iskierka>
and I'm just sitting there "... how does this compete with a little waterproof case on the handlebars plus by phone?"
<Fiora>
many early stage VCs bank on the fact that they will be able to pawn off their startup onto a greater fool later.
<Fiora>
ex: get a second stage round to boost the value, then acquihire. original VCs make some bank, employees get a job, everyone else get sscrewed
<bofh>
So, like, how does this differ from investor fraud, exactly?
<rqou>
it's not fraud? :P
<bofh>
Well apart from the fact that it's legal.
<Fiora>
it's not fraud if you're just trading money between white dudes.
<Iskierka>
I mean if you're selling them exactly what you're offering
<Iskierka>
and they're just too dumb to know what you're offering
<Iskierka>
https://www.hammerhead.io/pages/h1 oh here's the product that I never searched for at the time. They even offer smartphone integration. And just WHY NOT A CASE FOR THE PHONE?

the first thing I think when I see that is compositional differences but...either way
<SnoopJeDi>
(disclaimer: I am extraordinarily ignorant of the planets)

tbh same, and I'm actually reading thru some papers now in the hopes of more info
<SnoopJeDi>

yeah, that's an important clarification, *especially* when referring to the ice giants.

fuck I am still coughing. what's the opposite of an antitussive? cheapo laundry detergent works *wonderfully* as that.

<FluffyFoxeh>
lol a tussive
<bofh>
SnoopJeDi: yeah I'm seeing the same, tho the paper I'm reading makes no claims or guesses as to cause
<FluffyFoxeh>
bofh why were you sniffing laundry detergent
<bofh>
okay it appears the cough-inducing agent is *prolly* Sodium Percarbonate
<bofh>
FluffyFoxeh: so a gust of wind blew some everywhere and I breathed some in by accident
<bofh>
so it turns out "coughing fit" is a known adverse effect of accidentally inhaling sodium percarbonate, since it releases hydrogen peroxide on contact with water.
<FluffyFoxeh>
lol
<SnoopJeDi>
O_O
<bofh>
it turns out your throat doesn't like hydrogen peroxide, who knew.
<bofh>
SnoopJeDi: granulated laundry bleach :P
<FluffyFoxeh>
hydrogen peroxide, it's like water but with more oxygen
<bofh>
Yeah okay inhaling a tiny amount of oxiclean gives the same reaction and feels qualitatively similar.
<bofh>
...also remind me to never do that again.
<SnoopJeDi>
oh okay, the gradient is symmetric
<SnoopJeDi>
holy shit, the radio brightness temperature changed by ~10 K in some bands on Uranus between 1982 and 1984
<bofh>
I think it went from Uranian winter to Uranian summer in that time interval?
<bofh>
like I do know that the Voyager 2 flyby was at a time when the upper cloudbands were extremely inactive.
<SnoopJeDi>
hmm, seasons of 21 years, 2 years seems plausible for a change
<SnoopJeDi>
I guess being tilted on its gorram side makes for a very interesting Uranian year
<bofh>
Yep.

<FluffyFoxeh>
the question is essentially how do you orient a sector cut out of a circle to cover all the vertices of a square
<SnoopJeDi>
I'm just being a git anyway
<FluffyFoxeh>
and it's frustrating because none of it involves applying anything from the course material. I don't know the answer, and nothing we're taught in the course would lead me to it. it's a completely irrelevant thing to put on the assignment
<FluffyFoxeh>
it's not a bad question, I could accept it as an interesting maths puzzle. but not as an assignment for marks in a computer networking course where we didn't learn about this or any related problem or how to solve it
<FluffyFoxeh>
last assignment had us writing a proof for the three utilities problem. which was interesting, but I had to google the answer because I didn't happen to know it and this isn't a course on graph theory.

Oh, there it is. Now there's a little wheel to show the characters remaining instead of an actual number, how irritating

<kmath>
<eevee> essentially it's still 140, but low unicode (where latin, punctuation, etc are) only counts as half a character now https://t.co/sbxU96pOfP
<Iskierka>
the CJKV people are gonna be really disappointed if 280 still only gives them 140- yep

Whatever @fakeunicode's gender is, I'm certain that it cannot be expressed on the BMP.

<bofh>
so like it has a block size of 255, of which 32 chars are codewords, so that leaves 223 chars for the tweet, and up to 57 for the encoded symbols.
<Iskierka>
maybe they decided "let's not encourage people to find more 35k tweet bugs by giving them 280"
<Iskierka>
unfortunately it may have backfired in now everyone's disassembling 280
<bofh>
58 if we make the trailing newline of the message implicit
<bofh>
so we're still 6 short for a naive hex coding if we want to maximize blocksize (well, 7, for a separating space too)
<bofh>
but that still lets me tweet up to 216-char tweets w/o issue if I drop the ' 0x' prefix on each codeword symbol
<bofh>
not bad.
<UmbralRaptor>
Will bots be unable to use 280?
<Ellied>
my bot has 280
<UmbralRaptor>
Hm. So it might filter to 3rd party API clients?
<Ellied>
hmm, could try posting a 280 tweet from the bot's API
<Iskierka>
I mean it's ultimately up to twitter to reject, isn't it? should just be able to edit a number in the API so that the API won't question it first
<Iskierka>
although while you expect they'd have sorted server-side validation a long while ago I'm now wondering if that validation does the higher-unicode-as-2 or if that's just the webpage limit ...
<Ellied>
confirmed, can tweet more than 140 through api
