| 05:03.20 | klys | why assembly: because I want to make some pioneering osdev progress. why x86 assembly: personal preference adopted since linux came out, not trying to argue a point. |
| 05:05.15 | Enemby_ | me neither |
| 05:05.18 | Enemby_ | just curious |
| 05:05.40 | klys | so, how are you |
| 05:07.26 | Enemby_ | doing well |
| 05:07.35 | klys | anything new |
| 05:07.38 | Enemby_ | although I've slept for 12 hours like 3 days in a row |
| 05:07.43 | Enemby_ | something isn't right there |
| 05:07.54 | klys | yeah could be |
| 05:08.41 | klys | awaking prematurely isn't recommended though, because you get rheumatism that way (see: grey's anatomy, the book.) |
| 05:09.08 | Enemby_ | ugh |
| 05:09.15 | Enemby_ | let's just do away with this sleep thing |
| 05:09.36 | klys | well I was just working on my asm code today and am stuck at lidt [idt] |
| 05:09.52 | Enemby_ | TIS-100 is the extent of my knowledge |
| 05:10.02 | Enemby_ | mov sub uhhhh |
| 05:10.05 | Enemby_ | add |
| 05:10.07 | Enemby_ | done |
| 05:10.24 | klys | cmp push pop xchg in out |
| 05:11.21 | klys | do you code |
| 05:11.33 | Enemby_ | Yeah, javascript, C++ and lua sometimes |
| 05:11.45 | klys | c++ for cgi? |
| 05:12.03 | klys | or frontend |
| 05:12.50 | klys | j/c. |
| 05:12.53 | Enemby_ | gamedev stuff, sometimes front end sometimes not |
| 05:13.05 | Enemby_ | I use Unity, HTML5, and Love2D |
| 05:13.15 | Enemby_ | so there's quite a bit of varience |
| 05:13.27 | klys | okay, so unity meaning gnome/gnu/linux |
| 05:13.57 | Enemby_ | sorta |
| 05:14.03 | Enemby_ | it's a .net wrapper for mono, I think? |
| 05:14.08 | klys | oh |
| 05:14.21 | Enemby_ | using a weird mixture of C#, boo and javascript |
| 05:14.21 | klys | you use c++ for mono? |
| 05:14.30 | Enemby_ | No, I do javascript mostly |
| 05:14.35 | Enemby_ | C# when I really have to |
| 05:14.51 | klys | done some windows sockets api stuff? |
| 05:15.10 | Enemby_ | Not much beyond basic experimentation |
| 05:15.13 | Enemby_ | no practical use |
| 05:15.36 | klys | yeah, it's difficult coming at programming from the frontend these days |
| 05:15.53 | klys | so much to learn |
| 05:16.16 | Enemby_ | It's all good |
| 05:16.24 | klys | my fav. winsock function is WSAAsyncSelect() |
| 05:16.26 | Enemby_ | I've been coding for some 6-7 years |
| 05:17.07 | Enemby_ | somehow avoided networking thus far |
| 05:17.35 | klys | have you done data structures, compiler design, or operating systems research |
| 05:18.05 | Enemby_ | data structures |
| 05:18.09 | klys | coo |
| 05:18.18 | Enemby_ | I know how compilers and operating systems work, but not much more than that |
| 05:18.28 | klys | is that in lua or c# |
| 05:18.39 | Enemby_ | c# |
| 05:18.45 | Enemby_ | Syntax in lua is super weird |
| 05:19.00 | klys | is it infix, prefix, postfix, wierder |
| 05:19.57 | levi | Syntax in lua is super normal, everyone's just been poisoned by Ken Thompson's stylistic quirks. |
| 05:20.03 | Enemby_ | hahaha |
| 05:20.18 | Enemby_ | even so, using 'END' is unusual to me |
| 05:20.26 | Enemby_ | long live brackets and semi-colons |
| 05:20.40 | levi | In my day, we learned Pascal, and so 'end' was perfectly normal. |
| 05:21.23 | levi | That syntax came from Algol, which is the granddaddy of almost all programming languages in common use today. |
| 05:22.16 | Enemby_ | I learned on Visual Basic 5 |
| 05:22.21 | Enemby_ | so using end at all is scary |
| 05:22.27 | Enemby_ | hahaha |
| 05:22.34 | Enemby_ | don't want to kill the program, etc |
| 05:22.51 | levi | Algol 60, to be specific. Algol 68 got a bit more terse and used backwards keywords like 'fi' and 'esac' to end blocks. |
| 05:23.22 | levi | And that's why Bourne-family shell language looks like it does. |
| 05:23.42 | klys | how are you, levi |
| 05:23.48 | levi | I'm well. |
| 05:23.52 | klys | coo |
| 05:24.11 | klys | what have you been coding / up to |
| 05:24.24 | levi | Enemby_: If you think lua is weird, you ain't seen nothing. ;) |
| 05:24.48 | Enemby_ | valid |
| 05:25.50 | levi | klys: I have been coding a cut-down AVB (Audio-Video Bridging) network stack for a car amplifier that's going to go into a whole lot of cars. |
| 05:26.03 | klys | n1c3 |
| 05:26.11 | Enemby_ | don't mess up |
| 05:26.24 | klys | it's probably deterministic code |
| 05:26.56 | levi | It does precise time synchronization (although that's the part my coworker did) and media clock recovery from synchronized timestamps. |
| 05:27.08 | levi | So there's 500usec of latency over the wire. |
| 05:27.28 | klys | do you have hpet interrupts or similar |
| 05:27.59 | klys | high precision time |
| 05:28.34 | levi | I did most of the system bringup, low-level device drivers, build system, documentation system, overall system architecture, high-speed fixed-size block allocator, etc. |
| 05:29.11 | levi | The ethernet hardware has a timestamp mechanism coupled to an adjustable-rate timer. |
| 05:29.33 | klys | well okay. I remember a tsc speed test for allocation in school I did. first fit was fastest |
| 05:30.33 | levi | This is a straight bitmap with a single-cycle CLZ instruction. Fixed-size blocks fit in any slot. :) |
| 05:31.28 | klys | round-robin fit... |
| 05:31.52 | klys | ...seems like a natural solution |
| 05:32.14 | levi | Strangely enough the CPU is a weird PowerPC variant with variable-length instructions. |
| 05:33.02 | klys | car computers, I'm told are quite nonstandard |
| 05:33.06 | levi | Most of the audio playing is done via careful DMA programming, though. |
| 05:33.42 | klys | when I ask someone who knows about cars, though, he tells me most cars have the same cpu architecture |
| 05:34.41 | levi | Most cars these days have 10s to 100s of CPUs of various sorts communicating over several different networks. |
| 05:35.12 | klys | it sounds like an overgrown mess I just never got a handle on |
| 05:35.18 | klys | don't know where to start |
| 05:36.03 | levi | It's pretty crazy, but it's getting more standardized as they get more and more complex. |
| 05:36.49 | levi | They have at least got a fairly standard OS for the microcontrollers. |
| 05:37.06 | klys | which os do you think is good to point out |
| 05:37.37 | levi | It's specified (along with some other stuff) in some standards called Autosar. |
| 05:37.56 | klys | okay, perhaps I'll look sometime |
| 05:38.11 | levi | The OS bits were from a previous standard called OSEK. |
| 05:38.31 | klys | is that sort of like posix |
| 05:38.52 | klys | meaning, a standard which is system-agnostic |
| 05:39.01 | levi | Inasmuch as they are standards that define OS interfaces, yes; but the sort of OS that's defined is extremely different. |
| 05:39.16 | klys | so yeah |
| 05:39.44 | klys | do you code with signals or poll in loops |
| 05:40.40 | klys | seems like with a dma controller you'd spend some time waiting on i/o |
| 05:41.07 | levi | It's mostly agnostic to how you interface with things, although a couple of things depend on being called via interrupts. |
| 05:42.17 | klys | seen an intel atom board, levi |
| 05:42.59 | levi | Yes, some of our head units have been Atom-based. |
| 05:43.07 | klys | i see |
| 05:43.42 | klys | is that foreign or domestic |
| 05:43.55 | levi | The network audio packets come in at a rate of 8000 per second, and our Rx descriptor ring in the ethernet hardware has 4 slots. |
| 05:45.07 | klys | then perhaps you have to specify which slot to request when waiting for network i/o |
| 05:45.23 | levi | I don't know; I only work with the automotive division occasionally. We have head units and amplifiers and speakers in various makes and models though all the auto markets. |
| 05:46.24 | levi | No; it's essentially an array-based ring buffer. |
| 05:47.19 | levi | When you get an interrupt, you just consume the descriptors until you hit one the hardware owns. |
| 05:49.04 | klys | how about inputting data, do you wait for data from hardware in a handler or do you indicate where data is with a data structure and loop around the structure yielding when nothing is in there |
| 05:49.42 | klys | well I guess you say you could do it either way |
| 05:51.11 | klys | probably not best to go preemptive unless your timer is good, and it isn't, I suppose. |
| 05:51.35 | levi | We do some things via interrupts, other low-prority stuff via polling. |
| 05:51.44 | levi | There's no OS. |
| 05:52.08 | klys | perhaps you had considered the idea of multiple schedulers depending on priority |
| 05:52.18 | levi | Although we integrated it with an Autosar-compliant OS for the actual product. |
| 05:53.01 | klys | you must be familiar with that os then |
| 05:53.10 | klys | good enough |
| 05:54.08 | levi | Not terribly familiar with it, but it's pretty simple. I designed the rest of the stuff to not care much about the rest of the system. |
| 05:55.59 | klys | ^,,^ |
| 06:00.45 | klys | wasn't looking too close at this "80386 interrupt gate" illustration |
| 06:01.11 | klys | the "gate" is not a descriptor |
| 06:16.19 | klys | meh |
| 06:42.23 | levi | Hmm? |

| 17:23.55 | romanovic | harleypig: I don't know of a tailor who does custom fitted work, but my wife does a lot of alterations for people |
| 17:24.51 | romanovic | she does a lot of custom work too, but usually it is comiccon costumes or kids clothing. afaik she hasn't attempted custom fitted suits or mens clothing yet |
| 17:48.34 | SunSparc | Interesting you mention that. I have a couple of dress suits that I have been needing to get altered. My wife said there is a dry cleaner at BYU that also does alterations. Have not tried them yet though. |
| 17:51.07 | romanovic | i've had pretty good luck getting clothing altered at my local dry cleaners in SoJo, too. At least until I brought in a pair of pants, then they returned them to the wrong customer and never got them back to me |
| 17:57.59 | SunSparc | Lame |
| 17:58.27 | SunSparc | I guess the other customer really liked them. Maybe that means your tailor does good work. |
| 18:05.02 | harleypig | romanovic: Thanks. :/ I don't need alterations. I don't think, anyway. I need custom fitted pants, specifically, the legs. |
