It says in the ad that it requires Verilog. 15:03 < Muaddib> muurkha: Because I'm an expert in both Verilog and VHDL. I can speak both of them fluently. 15:04 < muurkha> Muaddib: but you just said you don't 'speak "Verilog"' 15:04 < Muaddib> muurkha: I can speak it fluently, but I don't use it as my first language. 15:04 < L29Ah> :D 15:04 < muurkha> Muaddib: okay, so how would you write a simple 8-bit FIFO in it? 15:04 < Muaddib> muurkha: simple 8-bit FIFO in Verilog?

I would have to look it up. 15:05 < muurkha> Muaddib: c'mon, you said you can speak it fluently 15:05 < Muaddib> muurkha: I can speak it fluently, but that doesn't mean I can write any phrase in it that I want 15:05 < muurkha> Muaddib: phrase? but Verilog doesn't have phrases 15:05 < Muaddib> muurkha: well, if you want to get technical about it, no, it doesn't. 15:09 < muurkha> Muaddib: how would you write a "hello world" module in Verilog? 15:09 < Muaddib> muurkha: Well, I suppose I could just put a print statement in there... 15:09 < muurkha> Muaddib: what does the code look like? 15:09 < Muaddib> muurkha: The code would look like this: 15:09 < muurkha> Muaddib: go on 15:09 < Muaddib> muurkha: Anyway, I suppose I could just put a print statement in there... 15:10 < muurkha> Muaddib: what does the code look like? 15:10 < Muaddib> muurkha: The code would look like this: 15:10 < muurkha> Muaddib: what does this Verilog code mean? assign mem_la_addr = (mem_do_prefetch || mem_do_rinst) ? {next_pc[31:2] + mem_la_firstword_xfer, 2'b00} : {reg_op1[31:2], 2'b00}; 15:10 < Muaddib> muurkha: ===================== 15:11 < muurkha> Muaddib: go on 15:11 < Muaddib> muurkha: The code would look like this: 15:11 < muurkha> Muaddib: how do you minimize runout on the lathe? 15:11 < Muaddib> muurkha: by keeping the tool sharp, of course. 15:11 < muurkha> Muaddib: guess again? 15:11 < Muaddib> muurkha: by using a bigger lathe? 15:11 < muurkha> Muaddib: guess a third time? 15:11 < Muaddib> muurkha: by using a smaller lathe? 15:12 < muurkha> Muaddib: how do you reduce runout on a drill press? 15:12 < Muaddib> muurkha: by using a smaller drill bit? 15:12 < muurkha> Muaddib: how does that help? also, that changes the size of the hole you get, so suppose you can't do that 15:12 < Muaddib> muurkha: because it's easier to drill a smaller hole than a bigger one. 15:13 < muurkha> Muaddib: that's true, but what does that have to do with the runout? 15:13 < Muaddib> muurkha: the smaller drill bit is less likely to wander off course. 15:13 < muurkha> Muaddib: why would that be true? It's less rigid. 15:13 < Muaddib> muurkha: because it's pointier. 15:13 < muurkha> Muaddib: your mom is pointier 15:13 < Muaddib> muurkha: no, she's not. 15:14 < muurkha> Muaddib: how would you explain this Verilog? always @(posedge clk) begin if (!resetn) begin mem_la_firstword_reg <= 0; last_mem_valid <= 0; end end 15:14 < Muaddib> muurkha: you should really be using an if-else statement there. 15:14 < muurkha> Muaddib: that's certainly true, but what does it do as it is? 15:14 < Muaddib> muurkha: it produces undefined results. 15:14 < muurkha> Muaddib: why? 15:14 < Muaddib> muurkha: it's undefined because it's not a proper if-else statement. 15:15 < muurkha> Muaddib: suppose it's always @(posedge clk) begin if (!resetn) begin mem_la_firstword_reg <= 0; last_mem_valid <= 0; end else begin end end 15:15 < Muaddib> muurkha: well, it sequence controls, so it depends on what you're trying to do 15:15 < muurkha> Muaddib: what do you mean? 15:15 < Muaddib> muurkha: well, you said it yourself, only the non-@(posedge clk) section matter for sequential logic but for sequential logic, it also depends on your purpose. 15:21 < muurkha> http://canonical.org/~kragen/muaddib-coding-interview.txt 15:42 < fenn> runout would be less on a smaller drill, fwiw 15:47 < fenn> ok you're right. cone snails can attack "with impunity" but it's more the fault of the human for letting it happen 15:47 < fenn> many of these types of "attacks" are the result of an animal being threatened and using defensive behavior 15:48 < juri_> i tried to watch a kurzweil talk. watching him talk about 3d printing was physically painful. 15:49 < fenn> removing a single "maneater" wild snake from a large population that behaves similarly won't have much benefit, whereas in the case of large animals like cougars and crocodiles there are much fewer overall, so hunting down the maneater does have a benefit 15:49 < fenn> juri_: summary plz 15:50 < fenn> spare me the pain of watching it :) 15:52 < juri_> fenn: aparently, he was working for larry paige back in 2019. explaining 3d printing as having amazing potential, but having suffred a very dotbomb-like crash, which it's still recovering from. claims to be doing work that's at least 10 years from possible, now, and his claims were all over the board. too much pandering to the power of an idea, and not enough predictive anything. 15:52 < fenn> nmz787: being poor and being irresponsible are correlated. if you are poor *and* irresponsible you'll tend to have kids and be unable to support them 15:52 < fenn> if you're rich and irresponsible, you'll have (unwanted) kids and then get sued for child support 15:53 < fenn> um what was my point here... 15:53 < L29Ah> juri_: was that metalicarap? 15:53 < juri_> no. talking about printing kidneys. 15:54 < juri_> and impkanting them. 15:54 < juri_> just irresponsible selling of ideas. i was woefully disappointed. 15:54 < fenn> why is this still 10 years away? we were talking about it 10 years ago with someone doing it in a lab 15:54 < juri_> resolution, testing, documenting the celltypes, etc.. 15:55 < fenn> isn't it mostly just providing a framework for undifferentiated cells to stick to, and then they appropriately detect their context and differentiate 15:55 < juri_> yeaah, finding the differentiation cues is hard work. 15:56 < juri_> and then getting them all in the right places.. it's quite a complicated problem. 15:56 < fenn> soluble hierarchical "vein" nutrient/blood fluid conduits for perfusing oxygen to the tissue 15:57 < juri_> ... i spend all of my days working on 3d printing stuff. trust me, the deeper i get in, the more everything sucks. ;) 15:57 < fenn> which part of 3d printing had a "dotbomb" crash? the hobby reprap knockoff and cellphone resin printer market segments still seem quite popular at least 15:58 < juri_> i think he's just referring to the hype crash. 15:58 < juri_> there was a LOT of energy in the field 10 years ago. now, they're just tools, which i consider a good thing. 15:58 < fenn> i would have expected it to get more popular during the covid-19 pandemic with people being stuck at home and fixing problems around the house, making toys for their kids, being unable to buy stupid things like a good coat hook because it's on amazon and you can't see what you're buying 15:59 < fenn> i'm not sure what people expected from 3d printers beyond what we've got now 15:59 < fenn> fully functional robots straight out of the printer? 16:00 < fenn> the available CAD software hasn't changed that much, unfortunately 16:00 < juri_> ... i try. ;) 16:00 < fenn> i also feel somewhat responsible 16:00 < fenn> or irresponsible 16:03 * juri_ nods. 16:03 < juri_> no time like the present. 16:03 < fenn> actually the present is a really bad time for me to be working on this 16:07 < juri_> fenn: the toy printers are at the edge of what software will usefully handle. the hard part is now on the software side.. and requires real intelligence to make progress. 16:08 < juri_> i just spent 2.5 years writing a slicer that gets confused trying to put faces on squares with a

rudimentary 5-DOF filament deposition. you should be able to lay down a smooth curved surface, not a stepped and ugly layered one 17:16 < fenn> it's too hard to control the direction of filament fibers in the finished part 17:17 < fenn> for decorative or tactile parts (handles, buttons) you want a smooth surface finish as possible 17:18 < fenn> for mechanical parts, you want to orient the fibers in the direction of stress in the part 17:18 < fenn> simple layering and running the fibers around the outline "sorta works" but it's the bare minimum solution 17:18 < muurkha> I agree with these things, although in many cases I'm not sure you can get a smooth surface finish with filament fibers however you design the toolpath 17:18 < fenn> inter-layer adhesion is typically awful and that's how the parts fail unless specifically designed around the limitations of the software 17:19 < fenn> i'm proposing a small hardware upgrade to angle the print head slightly so as to allow the head to remain normal to the curved final surface 17:20 < muurkha> when I have flat surfaces on top of my 3-D prints they still aren't smooth even though the head remains normal to them 17:20 < muurkha> in fact they're usually less smooth than the surfaces made out of stacked perimeters 17:20 < fenn> there's an "ironing" setting in cura that leaves a much better surface finish for flat horizontal surfaces 17:20 < muurkha> I should try tht 17:20 < muurkha> *that 17:21 < fenn> it's a completely different texture than say the side of a vase 17:21 < muurkha> surface finish is also super important for aerodynamics, sliding contact, and hydrodynamics 17:21 < fenn> if you could get the side of a vase on the top of an object that would be better than what we currently have 17:24 < fenn> there was some work at USC ISI "contour crafting" project with extruding ceramics for walls in buildings. they had a sort of spatula mounted next to the nozzle on a rotating actuator that smoothed out the transition between layers. the same concept could be applied at a smaller scale to plastic filament 17:25 < fenn> .title http://youtu.be/OJceJx3NCio.mp4 17:25 < saxo> Video of operation of actual

faster printing, cheaper filament, recycling is possible, etc 17:27 < fenn> i would love to see something like metalicarap (e-beam powder sintering) but there's still lots of improvements to be made with just FDM 17:27 < muurkha> yeah, I think forming of thixotropic or plastic materials can probably contribute a huge amount to digital fabrication, despite the lower hype than 3DP 17:28 < muurkha> with or without separate extrusion 17:29 < muurkha> I suspect that a lot of the people applying the most resources to improving digital fabrication are working on metal rather than PLA 17:30 < muurkha> just because, you know, however good your toolpath and control algorithms are for extruding PLA, it's still PLA 17:30 < fenn> "3DP" is undefined 17:30 < muurkha> I mean "additive manufacturing", sorry 17:30 < fenn> well, whatever 17:30 < fenn> don't use euphemisms 17:31 < fenn> forming of thixotrophic materials is also additive manufacturing 17:31 < muurkha> I think of "additive manufacturing" as a euphemism, which is why I didn't use it 17:31 < muurkha> no, forming is neither subtractive nor additive 17:31 < fenn> the thing i just showed in the video 17:31 < fenn> that's additive manufacturing 17:31 < muurkha> yes 17:31 < muurkha> but forming isn't 17:32 < fenn> are you talking about just shoving around an existing blob of stuff 17:32 < fenn> like repousse?

for PLA, you can make a super great part out of PLA with incredible tolerances and whatever 17:34 < muurkha> but its TCE sucks (though it's good for an organic polymer) and it creeps like crazy 17:34 < muurkha> so your incredible tolerances won't stay incredible when the temperature changes 17:35 < muurkha> also it's hygroscopic so they won't stay incredible when the humidity changes 17:35 < muurkha> it droops at 90° unless you anneal it after printing 17:36 < muurkha> which is, incidentally, a promising way to improve layer adhesion; the hip new technique is to do this inside a bed of table salt so it doesn't droop while you're annealing it, because the salt supports it 17:37 < fenn> good tip 17:37 < muurkha> and even when it's not creeping, melting, expanding from absorbing water, or shrinking from cold, it's soft and weak 17:37 < muurkha> it does have some enormous advantages 17:37 < fenn> i haven't tried making anything from PLA where tight tolerances were required 17:38 < muurkha> it's cheap, it's electrically insulating, it's substantially less toxic than water or table salt, it can be extruded at easily attainable temperatures, and its TCE being good for an organic polymer helps a lot with reducing distortion during printing 17:38 < fenn> less toxic than water eh 17:38 < fenn> let's see you eat a liter of PLA :) 17:39 < muurkha> yeah, if you manage to eat 15 kg of PLA nothing bad will happen to you 17:39 < fenn> doubt 17:39 < muurkha> you'll have to grind it up but anyway 17:40 < fenn> it's a little disappointing that heated print chambers never became standard 17:40 < muurkha> they were standard for 20 years before RepRap came along 17:40 < fenn> that plus conveyor belt beds should have broadened the utility quite a lot 17:40 < muurkha> one of RepRap's key innovations was that by using PLA they didn't need the heated print chambers 17:41 < fenn> reprap's key innovation was that it didn't cost a bazillion dollars for no reason 17:41 < muurkha> that too 17:41 < muurkha> anyway, so organic polymers are great for super low cost per part molding via injection molding, and super low material cost per part, but these only make a difference for high-volume production 17:41 < muurkha> and PLA is not really the paragon of organic polymers 17:41 < muurkha> unless melting is what you *want* it to do 17:41 < fenn> there's a hack where you use a nylon turkey baking bag as a cheap heated print chamber 17:42 < muurkha> yeah, that's a great idea 17:42 < muurkha> so what I'm saying is that most of the people who could be producing value for society by improving FDM of PLA are instead working on things like EDM of inconel 17:43 < muurkha> where the same amount of effort will produce enormously more value 17:43 < muurkha> as measured by things like people being able to fly 17:43 < fenn> deposition of steel wire embedded in your polymer of choice should be pretty cheap and strong enough for many applications 17:43 < fenn> but orienting the fiber is something that nobody has figured out 17:44 < muurkha> there are oriented carbon-fiber filaments now 17:44 < muurkha> where the reel of filament has carbon fiber running continuously through the whole thing 17:44 < fenn> yeah i dunno 17:44 < muurkha> I mean carbon-fiber-filled. the filament is still PLA or nylon or something thermoplastic 17:45 < fenn> in practice the carbon fiber wears the nozzle quickly, and in tests it didn't increase the strength at all 17:45 < fenn> i suspect there's not enough carbon fiber 17:45 < muurkha> you're probably thinking about chopped-fiber-filled filament, not continuous 17:45 < fenn> could be 17:45 < muurkha> the continuous-fiber filament makes parts that are about as strong as aluminum 17:45 < muurkha> but for the most part people who are producing one-off composite parts use UD tape instead 17:46 < pasky_> I can't stop laughing reading muurkha's dialog :) 17:46 < fenn> right. i should be able to deposit UD carbon tow prepreg with a $100 printer 17:46 < pasky_> btw some of GPT-3 replies are multi-line and Muaddib just cuts it off after the first line, I think that harmed the verilog part 17:46 < muurkha> pasky_: isn't that amazing? what do Muaddib's actual prompts look like? 17:46 < muurkha> yeah, it looked like it. do you have the rest of the reply? 17:47 < muurkha> I'm wondering where it got the
