<soundnfury> that's about the same size as a real function, yes? (assuming finite dimension > 1)
<bofh> I think so.
<Ellied> professor life goals: require papers submitted in plain text format (ASCII, UTF-8, UTF-16, whatever, so long as the encoding is clearly indicated) with length boundaries given in bytes.
<Ellied> LaTeX source code is also perfectly acceptable
<bofh> I still prefer--yeah okay
<bofh> LaTeX source code was literally what I was going to say
<UmbralRaptor> Hah
<UmbralRaptor> [screaming internally] https://twitter.com/Collaterly/status/932744049059966976
<kmath> <Collaterly> ahahaha we have a saline shortage in large part because most US saline was manufactured in puerto rico, and WHOOPS… https://t.co/KbFMdcNiHJ
<soundnfury> Ellied: I am disturbed that you find UTF-16 acceptable
<UmbralRaptor> soundnfury: That just means you can use the malgolge.js framework.
<UmbralRaptor> (I hope that's not a thing)
<soundnfury> BOMs for the BOM god, surrogates for the surrogate throne
<soundnfury> UmbralRaptor: d'you mean malbolge?
<soundnfury> clearly the backend runs Malbolge On Mechanisms
<Ellied> I legitimately don't know, what's wrong with UTF-16?
<UmbralRaptor> soundnfury: I do.
* UmbralRaptor is under the impression that UTF-16 only supports the BMP.
<soundnfury> UmbralRaptor: nah, that's UCS-2
<soundnfury> Ellied: UTF-16 has "surrogate pairs", a horrid hack to go beyond the BMP
<soundnfury> which makes it a variable-length encoding
<soundnfury> but since non-BMP characters don't make it into most people's testing environments, everything from the Windows API upwards tends to be buggy when it comes to surrogates
<soundnfury> also, UTF-16 is endianness-sensitive, which leads to the BOM (another nasty hack)
<Ellied> gotcha
<soundnfury> oh, and unlike UTF-8, _any_ byte can appear in the middle of a UTF-16 stream
<soundnfury> whereas UTF-8, for instance, never embeds NULs
<soundnfury> and also the low-half only ever appear as themselves
<soundnfury> (the former is a special case of the latter)
<soundnfury> which is why UTF-8 was originally proposed under the name "FSS-UTF": File System Safe Unicode Translation Format
<soundnfury> because '/' doesn't appear other than as itself ;)
<UmbralRaptor> Note to self: throw emoji at testing environments.
<UmbralRaptor> rqou: Just so I'm clear, my C2D and C1D are too old to be vulnerable, and Apple doesn't have ME enabled on their hardware so my i5 MBA is safe? (from that ME thing)
<rqou> er, what?
<rqou> oh, the recently revealed intel ME vulns
<rqou> it might still be vulnerable to something because ME is always active on newer devices even if you don't have AMT/vPro
<rqou> but i don't know the details
<UmbralRaptor> AAAAAAAA
<soundnfury> UmbralRaptor: how long until there is a principia release named after that well-known mathematician, Person Raising Both Hands In Celebration?
<UmbralRaptor> Uh
<SnoopJeDi> ?
<UmbralRaptor> ?
<SnoopJeDi> so a friend asked me if I knew any good node.js resources, and I replied: "You might try to find fairly simple router examples to understand the module system and streams. Async is a mess like in every language, i think promises are idiomatic node atm but not very sure"
<SnoopJeDi> "Can you say that again in a way that a 5th grader would understand?"
<SnoopJeDi> Rabbit-hole digression GO
<Ellied> wait, recent ME vulns? how recent?
<Ellied> oh fuck, article from the Register 2 hours ago?
<FluffyFoxeh> ruh roh!
icefire has quit [Read error: -0x1: UNKNOWN ERROR CODE (0001)]
<Ellied> my vision of the IME is basically "hey, let's install a pipe that goes from the liquid fluorine tank to the intake of the supersonic wind tunnel. But don't worry, we'll put a valve on it!"
<UmbralRaptor> @mjg59 isn't panicking *yet*, but it's a real possibility.
<UmbralRaptor> Where the worst case is "throw out any <10 year old Intel hardware that spends any time online"
<UmbralRaptor> I think?
<SnoopJeDi> just throw out the hardware because what's left of "online" at that point?
<FluffyFoxeh> been wanting to upgrade to Ryzen for a while
<Ellied> Not sure if I have a computer that has one. Toughbook likely does not, HP doesn't (but might have something equally horrid from AMD), netbook likely does (i5-something), old Dell could go either way
<FluffyFoxeh> :p
<Ellied> Toughbook might, actually. Thinkpad from I think about the same generation has one, there's a switch for AMT in the bios
<FluffyFoxeh> something important that has never been made clear: Would such an exploit be blocked by NAT or an external firewall?
<Ellied> I think the likelihood of this affecting most users is low, but that's kind of not the point
<UmbralRaptor> ¯\_(ツ)_/¯
<UmbralRaptor> Be *very* careful about what Wi-Fi networks you connect to?
<Ellied> The point is that Intel have put a thing in everyone's computer that *really looks like* hardware-spyware (hardspyware? spyhardware?) and refused to prove that it's not (e.g. by releasing the source for the firmware). As far as a non-Intel tech is concerned, it could be anything, and the fact that it has full asynchronous access to the machine's memory *and* unregulated network access is scary.
<FluffyFoxeh> Ellied: oh I know, it's fucking awful
<FluffyFoxeh> I hate every bit of it
<FluffyFoxeh> but it'd be nice to know how to render it inert
<FluffyFoxeh> at least for my own system
<whitequark> whoooo pings me here
<Ellied> I wonder if the OS can capture traffic to ports 16992 and 16993 before the IME does
<whitequark> no
<whitequark> I've read how it works
<whitequark> it can neither capture nor detect that in a typical setting
<Ellied> alas
<whitequark> in certain misdesigned boards it can detect that
<FluffyFoxeh> I'd like a misdesigned CPU that doesn't have a proprietary death-blob that I'm not allowed to use or even look at
<Ellied> in a system with AMT enabled, will those ports return anything that would signal its presence to a tool like nmap?
<whitequark> Ellied: now that is a question I don't know the answer to offhand
<Ellied> I can probably test that with the old laptop I've got with a switch in the BIOS for AMT, but probably not conclusively
<Ellied> I tried probing 16992 and 16993 on my friend's laptop the other day (new enough to have one, but not business enough to have its services enabled) and got nothing
<Ellied> I don't quite understand why machines that don't appear to support AMT/vPro would have an IME
<whitequark> oh that's easy
<whitequark> first, AMT is not enabled by default, and you have to explicitly enroll in it
<whitequark> otherwise it will keep silent
<whitequark> even more, disabling it explicitly will kill it "forever"
<whitequark> second, IME brings up various random shit in the SoC
<whitequark> they just put all the junk they weren't quite sure where it should go into the ME
<whitequark> I vaguely recall that IME used to not even have any network connection or something, it was used for just that
<whitequark> but I may misremember
<Ellied> does that mean that, for now, attacks involving the IME are assumed to be limited to software already running on the target machine, and hijacking it solely over the network if AMT is turned off (or has no way to turn it on) probably isn't possible?
<whitequark> I don't know.
<whitequark> it might be still listening on those ports and just refusing connections.
<whitequark> in that case, vulnerabilities in the network stack will screw you.
<whitequark> I have a *really* bad feeling about this.
<Ellied> ah.
<Ellied> forgive me for my poor understanding of networking, but can you expound on that a bit, particularly network stack vulnerabilities? I guess my general question is, how would it be communicated with at all if it's not accepting connections
<whitequark> let's say it receives a packet, lets the TCP/IP stack process it, and then passes it to higher levels
<SnoopJeDi> I'd hazard a guess that refusing connections doesn't necessarily mean it's not accepting *any* connections
<whitequark> the higher levels always refuse to do anything
<whitequark> but if e.g. the TCP engine itself has a buffer overflow in SYN handling
<whitequark> then... oops
<Ellied> is the TCP/IP stack part of the IME (and therefore inside the "blackout zone" of opaque firmware) or am I misunderstanding again
<Ellied> I suppose that's not an exclusive or
<whitequark> IME has access to raw Ethernet packets filtered by certain hardcoded conditions in the GbE adapter
<whitequark> everything past that it has to decode itself
<Ellied> so you could just send ~something~ in a packet to the IME and it would receive it, even if it didn't formally open a connection?
<whitequark> I mean
<whitequark> how do you think pings and TCP SYN packets work?
<whitequark> you have to start the connection *somehow*
<whitequark> this means you need to parse it
<whitequark> this means LOL C
<Ellied> sure, I guess the alternative I imagined was that the networking hardware is responsible for initiating and managing connections, but that doesn't make much sense now that I think about it
<whitequark> no, that's perfectly plausible
<Ellied> Do you think the IME's firmware intentionally contains behavior that would allow the machine to be compromised remotely?
<whitequark> (... if your hardware division is any good at formal verification, that is)
<whitequark> azonenberg did a hardware TCP/IP stack
<Ellied> oh, okay.
<whitequark> intentionally? hell no.
<whitequark> that would be suicidal for Intel.
<whitequark> it doesn't matter though because their firmware is just... that bad
<whitequark> "Intel intentionally backdoored AMT" is right up there with "Bush did 9/11"
<whitequark> the level of incomprehensibly insane that only a person completely divorced from objective reality can even start to contemplate
<SnoopJeDi> vulns are a particularly apropos place for application of Hanlon's Razor and Sturgeon's Law, in equal measure
<Ellied> I understand that they wouldn't *want* to, but a lot of people are concerned about the NSA/CIA/DOJ here in the states compelling companies to do this sort of thing, particularly since they don't seem to understand that encryption backdoors aren't gonna work (see: recent statements from DOJ regarding ""responsible encryption"")
<Fiora> i doubt intel would accept that quite honestly
<SnoopJeDi> same
<Fiora> intel is too powerful. they have absolutely no need to listen to anything the NSA says
<SnoopJeDi> they're holding NSA by the digital balls as a fab expert, too
<Ellied> hmm, alright
<Ellied> I suppose it continues to be encouraging that they have so much trouble getting into iphones.
<SnoopJeDi> perhaps thankfully, mustachioed villains are rarely a necessary invocation
<SnoopJeDi> (romantic though they are)
<Fiora> Ellied: firstly
<Fiora> if you mean radios
<Fiora> i trust qualcomms radios about 100000x less than intels
<Fiora> if you think intel is bad, you have no idea how bad the rest of the industry is
<SnoopJeDi> still waiting on John McAfee to eat that shoe, tbh
<Fiora> secondly, if you mean chips, intel gave up on phones a while ago
<Fiora> thirdly, if you mean fabbing, pretty sure intel's gonna be fabbing apple chips at some point at this rate
<Ellied> I meant more generally, e.g. "oh good, Apple isn't already backdooring their phones for the NSA"
<Ellied> but yes
<whitequark> oh my god qualcomm
<Ellied> I'm trying to tread lightly because of how little I know about the semiconductor industry but it's already clear that I spend too much time on twitter
<whitequark> intel knows at least *some* of the shit they're doing
<SnoopJeDi> conspiracy theories are fun and malicious bad guys are simple
<whitequark> qualcomm is almost right up there with malicious negligence
<whitequark> and don't get me started about qualcomm-atheros
<Fiora> worse
<SnoopJeDi> not that the NSA aren't malicious, but fewer tooth fairies is usually good
<Fiora> qualcomm is definitelyw orse than amlicious negligence
<whitequark> I'm pretty sure it was a qualcomm radio that *was* in fact backdoored but that was a very long time ago
<whitequark> (you send it a special ping & it mirrored all traffic)
<whitequark> like 15 years or something
<whitequark> also just fucking look at qualcomm's code
<Fiora> they are the worst patent troll in the industry, they are notoriously secretive (apple has absolutely nothing on them), they are a humongous corporate bully, their code is generally atrocious
<whitequark> I can write it better while blindfolded, drunk, high on ketamine and without SoC documentation
<Ellied> I wouldn't take that statement literally from anyone but you.
<whitequark> I am exaggerating. slightly.
<Fiora> here's a fun little fact
<Fiora> do you know why samsung's phones in the US ship quallcomm SoCs? even though samsung makes their own? and samsung uses them everywhere else
<SnoopJeDi> [narrator] the fact was probably not going to be very much fun
<whitequark> i do
<whitequark> lol
<Fiora> 10% of it is CDMA support, but they could always use a separate modem anyways, like everyone else does.
<Fiora> the other 90%
<Fiora> is that qualcomm and samsung agreed to a mutual bribe in which qualcomm will fab their chips on samsung fabs in return for samsung shipping their chips in the US
<whitequark> wait what
<Fiora> yes
<Fiora> AFAIK.
<Fiora> did you have another one
<whitequark> this is not even the reason that I expected but
<whitequark> this is WAY BETTER
<Fiora> LOL
<SnoopJeDi> horizontalest of integrations
<whitequark> Fiora: I only knew it partially it seems
<whitequark> amazing
<whitequark> this is so... so semiconductor industry, it hurts
<Fiora> also qualcomm is one of very few large tech companies in the world to have patent-trolled over standards-essential patents.
<Fiora> the others are google (through motorola mobility) and i'm not sure who else. dolby has extremely bad patent behavior but they're not that large and it's mostly over their own formats.
<Fiora> the main reason hardly anyone makes wifi radios is because qualcomm looms over them like a giant anteater sitting outside the anthill
<whitequark> lol @ that analogy
<whitequark> doesn't google use MoMo patents only defensively?
<whitequark> I thought that was the idea
<Fiora> hahahahaha no
<whitequark> christ
<whitequark> I should have expected
<whitequark> *sob*
<Fiora> they demanded $4b/year for h264 and 802.11 standards-essential patents (patents which were a very small portion of the overall pool, and clearly not worth more than a very small portion of the total pool)
<Ellied> I'm suddenly even more glad that I didn't continue down the path of electrical/computer engineering.
<whitequark> fucking hell
<whitequark> Ellied: eh
<whitequark> it's a fun thing to do
<whitequark> I mean, stay away from college, obviously :p
<Fiora> the only reasonable excuse i've heard is that the lawsuit started before motorola was bought
<Fiora> but google could have just..... killed it
<UmbralRaptor> Wait, 802.11 is still patented? Wasn't that in hardware in the 90s in some cases?
<Fiora> i'm pretty sure microsoft would have happily said "hey thanks google now we don't have to deal with this garbage thanks"
<Fiora> note: they were carrying out a patent trolling lawsuit against h264 while *at the same time* talking about the evils of video patents
<UmbralRaptor> whitequark: only because grad students will be looking at defacto 30%-80% income taxes if the senate bill goes through.
<UmbralRaptor> s/./?/
<whitequark> UmbralRaptor: 802.11ac?
<Fiora> i suspect this is more incompetence (two hands doing different things) than malice, but it's still hiliarious.
<Qboid> UmbralRaptor meant to say: ?hitequark: only because grad students will be looking at defacto 30%-80% income taxes if the senate bill goes through.
<Ellied> swing and a miss.
<Ellied> s/./?/g
<Qboid> Ellied meant to say: ?????????????????
<UmbralRaptor> Oh, hey. Qboid supports wildcards now.
<Fiora> also whitequark i'm basically having silicon fab problems atm
<Ellied> whitequark: I have no doubts that the work is cool, I'm just not sure I'd like being caught up in all these industry politics and corporate wars
<Fiora> i'm doing fabric dyeing and i'm trying to replicate a past success in a small batch using a large batch and failing
<Fiora> and there's like 7 different variables involved
<Fiora> and i don't understand their interactions
<Fiora> so i'm basically going all "copy perfect" mode and attempting to precisely replicate the process between batches and vary precisely one variable until i get it
<whitequark> Fiora: hahahahaha
<Fiora> it feels obnoxiously engineering in the worst possible way
<whitequark> welcome to literally every batch industrial process ever
<Fiora> YES.
<Fiora> i only have another 9 yards of cheapass silk
<Fiora> better get it right soon
<Fiora> that or find a way to bleach silk
<whitequark> do you know how fucking much work goes into making the white plastic on both sides of the macbook charger have the exact same shade of white?
<whitequark> this is an INCREDIBLY HARD PROBLEM
<whitequark> this is also why every sane vendor just makes their chargers fucking black
<Fiora> oh i can believe it. see, not only do i have to replicate it in a large batch
<Fiora> i need to dye precisely two pieces of fabric, roughly 2.5 yards
<Fiora> the same color
<whitequark> bleaching silk...
<Fiora> oh yes and i discovered in the large batch scale up
<Fiora> it SHRINKS BY ABOUT 15%
<Fiora> IN ONE DIRECTION
<whitequark> yay anisotropy!
<Fiora> oh the silk weave is the worst fucking anisotropic disaster ever
<Fiora> because, well, it's a satin weave
<Fiora> it's basically the fabric equivalent of unidirectional carbon fiber
<Fiora> it literally curls up into a tootsie roll when you wet it
<Fiora> and yes you can't bleach silk the classical way. chlorine literally dissolves it
<whitequark> what
<whitequark> you mean chlorine bleach right
<Fiora> yes
<Fiora> as in, sodium hypochlorite
<whitequark> right
<whitequark> what about conc H2O2?
<Fiora> apparently you can do *something* using sodium hydroxide and hydrogen peroxide
<Fiora> hydrogen peroxide 3% did nothing
<whitequark> predictably
<Fiora> basically you need to eliminate hydrogen bonds
<Fiora> acid dye is hydrogen bonded to the protein chains
<whitequark> wait, your methoddoesn't make much sense to me
<whitequark> NaOH will hydrolyze the peptide bonds, and H2O2 will attack the dye itself
<whitequark> "H2O2 in basic solution" makes more sense but is still odd
<Fiora> that's what i found on google
<Fiora> peroxide and lye and soap
<Fiora> but even that sounds dubious. silk hates basic solutions
<whitequark> just like anything made from proteins ever
<whitequark> itmight survive *slightly* basic solutions for a not long time
<Fiora> one thing i don't understand though
<Fiora> apparenly vinegar is GOOD for silk
<Fiora> like, you wash it in highly vinegar'd solution to re-shine it?
<Fiora> but nobody explains why
<whitequark> hrm
<whitequark> let me think about it
<whitequark> what's the isoelectric point of silk proteins
<UmbralRaptor> ;8ball is the levi-civita tensor magic?
<kmath> UmbralRaptor: Yes
<UmbralRaptor> That would explain how it seems to make matrix multiplication commutative.
<rqou> hmm reading through backlog i see mention of qualcomm cdma patents?
<rqou> i've got a phone right now that has the best workaround for that feature
<rqou> it supports CDMA only with one specific carrier

<SnoopJeDi> bofh, the explanation of SSB on this page is so SO bad. I hate this book for how badly it flubs when it's clear the *author* knows the subject https://books.google.com/books?id=T6PjIRx26FIC&pg=PT184&lpg=PT184#v=onepage&q&f=false
<SnoopJeDi> I didn't know anything about SSB before I read that page last night but it frustrated me so badly that I put the book down and spent 5 minutes on wikipedia just so I wouldn't internalize the bad description.

<kmath> YouTube - Doctor Who Proms 2010 - I am The Doctor
<bofh> SnoopJeDi: like SSB is just... take your signal, and amplitude modulate it by a carrier cos(w_c*t). then you get your upper sideband cos((w_c+w_s)*t) and your lower sideband cos((w_c-w_m)*t). for single sideband either lowpass, highpass, or hilbert transform the input signal first, modulate that too, then sum the two modulated ones.
<bofh> cos((w_c-w_s)*t)*
<bofh> that's for a sinusoidal signal cos(w_s*t), for the general case just expand your signal f(t) in a fourier series.
<bofh> and remember that bandlimited functions and periodic functions are effectively the same thing from a harmonic analysis perspective (proof: do the appropriate mapping from \mathbb{T} to the real line, then invoke Nyquist-Shannon-Kotelnikov's Sampling Theorem)

<SnoopJeDi> I *really* wish I'd bookmarked it, but Eccleston did an interview about being the Doctor in which he laid out very explicitly why he's a good influencer: he revels in the unknown rather than fearing and demonizing it
<bofh> Sounds like The Doctor, tbh.
<SnoopJeDi> right? Particularly 9
<bofh> (I agree, and that persona did come thru in the Eccleston and even somewhat in the Tennant years)
<SnoopJeDi> like the very first episode is him being like "weird aliens, COOL!"
<bofh> YEP.
<SnoopJeDi> and it's a nice constrast to the shoot first ask questions never trope
<SnoopJeDi> "hmmm maybe anthropocentrism is super unethical ?"
<bofh> I honestly can't watch shows that have that as a core mentality, it's simultaneously boring and emotionally exhaustin.
<SnoopJeDi> I can barely make the deliberate effort to watch *anything*
<SnoopJeDi> case in point: I haven't seen any of the 12th Doctor
<Iskierka> I've seen very little of 11 or 12 and don't especially care to. Hopeful for 13
<kmath> <KrangTNelson> american politics is a sophisticated balancing act where once a month the government tries very hard to kill you an… https://t.co/fpBXtXXbWn
<bofh> SnoopJeDi: same honestly, but that's more I have an awful attentiom span for video
<SnoopJeDi> I'd say "same" but I think my attention span just sucks in general
<SnoopJeDi> waited on bated breath for my assessment results

<egg|zzz|egg> NomalRaptor: moo
* egg|zzz|egg pokes NomalRaptor with Einstein summation
<kmath> <bofh453> @FioraAeterna I... what the fuck. brb papers.
* NomalRaptor explodes on a shower of Kronecker delta functions.
NomalRaptor is now known as UmbralRaptor
* Ellied explodes into a single Dirac δ-function in the form δ(αr-βt) (constant Θ and Φ)
Ellied is now known as Ellieded
<UmbralRaptor> D:
<egg|zzz|egg> grumble grumble tis a tempered distribution, not a function grumble
* egg|zzz|egg tempers Ellieded
<bofh> egg|zzz|egg: I just consider it a point-mass measure.
* UmbralRaptor wonders if egg means mathematically or metallurgically.
<UmbralRaptor> (Okay, obviously math.)
* UmbralRaptor x_x
* UmbralRaptor is once again annoyed at needing food. o_O
Ellieded is now known as Ellied
<Ellied> So I tried turning on AMT on the thinkpad and scanning it
<Ellied> No responses from those ports, and it also appears I can detect the packets sent to those ports in wireshark
<UmbralRaptor> \o/
<Ellied> not sure if that's a good thing?
<Ellied> I was hoping to figure out a way of detecting the presence of a networked IME on my machines, and this doesn't appear to be working
<UmbralRaptor> I'm assuming that this means the IME is nonfunctional.
<Ellied> or nonexistent and the BIOS is confused. It's an incrementally newer chip than in my toughbook but not by much
<bofh> I should run MEcleaner on my newer machine.
<egg|zzz|egg> UmbralRaptor: so, do you understand the summation convention
<UmbralRaptor> egg|zzz|egg: I think so.
* egg|zzz|egg pets UmbralRaptor with indices
<whitequark> Ellied: it's not asking the GbE adapter to intercept packets
<kmath> <MikeIsaac> i need to correct this: this was a separate incident in 2014. current 2016 breach was a different breach. so that's… https://t.co/U2sYY8AbOJ
