asciilifeform: where my father worked they had always 3 bins. ☟︎

asciilifeform: now it is O(N^2) process to learn why.

asciilifeform: the defective transistors no longer 'packaged separately for your convenience esteemed sir'

asciilifeform: so i suspect they are already following mircea_popescu's tip.

asciilifeform: judging by what i get in the crates here.

asciilifeform: i bet the chinese dun test no moar.

asciilifeform ~likes~ this approach. but it has limitations.

asciilifeform: sometimes there are actual constraints...

asciilifeform: it is 1920s and armies are interested in aviation! except for mircea_popescu's army. he instead ordered all conscripts who can't jump 10,000 metres in the air and stay up by flapping their wings, shot !

asciilifeform: that's the real boojum, and not only of this, but of all other questions re chip.

asciilifeform: at any rate, until this, whether or not chip maker listens to mircea_popescu and omits test circuit or not, the buyer CANNOT verify

asciilifeform: (can even use ~analogue~ optical comparator! ever seen one? they used to exist in machine shops.)

asciilifeform: this is one of the reasons i wrote 'must have fpga, with quartz window'. you can inspect a ~regular~ geometric structure far more easily than any other kind

asciilifeform: until then, we are in a state of sin regardless of how.

asciilifeform: thing is, computer rides on 'promise', not protocol, because there is no way of inspecting the dies.

asciilifeform: until silicon can be made piecewise, like a printer page, rather than photographically by the million copies, we are stuck with it. (and antifuse costs 0 and eliminates problem, so i have nfi what mircea_popescu is smoking)

asciilifeform: it is nonsense, what can i say. and the folks who build machine this way, will come to grief.

asciilifeform: why test parts!

asciilifeform: let's test whole thing!1111

asciilifeform: i will listen to this nonsense after mircea_popescu has a plane built according to this philosophy and flies in it.

asciilifeform: can make 'we tested, we're done nao.'

asciilifeform: but there is such a thing as antifuse.

asciilifeform: fact is, you dun test ~everything~ that can be tested before it costs you perfectly working and costly rest-of-the-box, you go broke.

asciilifeform: when you solder 1 dud to 99 working components you paid for.

asciilifeform: you go broke today

asciilifeform: if you dun test the chipz before soldering'em down, you go broke.

asciilifeform: there is such a thing as % yield.

asciilifeform: mircea_popescu: mno, you cannot take it out. because then cannot test the unit.

asciilifeform: problem is that , as with nearly every aspect of vlsi, the described function is ~promise~ not protocol.

asciilifeform: done testing ? blow.

asciilifeform: it would not be so hard to implement, just put antifuse link in the relevant circuit

asciilifeform: incidentally, ~every piece of silicon on the board has a debug port of some form, the cpu jtag thing is simply the handiest one, and the closest to being in some form documented.

asciilifeform: (and in what there is not, can be replaced in the post for a physically-indistinguishable version that does)

asciilifeform: at any rate, and as i wrote long ago, imho soldered-in 'bugs' are quite obsolete - there is built-in hole in ~everything made for eons now.

asciilifeform: (and its existence was, apparently, quite surprising to the monkeys, who never once gave a thought to subj of how mb is tested at factory)

asciilifeform: it isn't 'exploit', that was idiot media spin, it is simply a handy place to plant a widget.

asciilifeform: what to ~do~ with it, is up to the user's imagination !

asciilifeform: y'know, factory test plug.

asciilifeform: fella claims to be ~66 y.o., which makes him my oldest (known) reader.

asciilifeform: ^ one useful find, he turned up some boxes where the connector is on ~under~ side of mb, and difficult to inspect

asciilifeform: but tried.

asciilifeform: and tearing

asciilifeform: unless you can also conjure up materials with ~same speed of sound~, there will be refraction

asciilifeform: and how much sense does it make to gild this lily for infantryman (vs sniper) ?

asciilifeform: that this is the abstract 'how' - yes. but achieved ?

asciilifeform: what do they actually issue ?

asciilifeform: mats: i always wondered, what keeps the mirrors, prisms, etc in that $700 box from whanging out of alignment after 1000 shots

asciilifeform: it wasn't in the catalogue i read...

asciilifeform: eotech makes a thing that comes with eyes you can implant in your ballsack ?

asciilifeform: show me scope that helps in, e.g., this position, http://xn----7sbfkccucpkracijq8iofobm.xn--p1ai/images/stories/nauka/sniper/sniper-izgotovka-k-strelbe-navskidku-6.jpg

asciilifeform: link to example ?

asciilifeform: with the exception of laser, they all require eyes to be approx level with the glass, neh?

asciilifeform: mats: that scope makes 0 sense on a weapon designed for use at musketry range ?

asciilifeform: yes, this is supposed to be a tr0l0l, but still poorly thought through.

asciilifeform: to what addr would they move it? the unknown one, engraved inside his eyelid?

asciilifeform: all but the barrel

asciilifeform: (quite seriously, whole thing is covered in rack to which can Hang Shit Off)

asciilifeform: hence the rhyme

asciilifeform: but also toy soldiers

asciilifeform: (large toy maker at the time)
