| ex-parrot | Still grinding my way through LFS | 08:53 |
|---|---|---|
| ex-parrot | I’ve been doing a couple of hours every 2nd day or so. Few small aarch64 issues to fix along the way but I didn’t get stuck yet | 08:53 |
| mntmn | ex-parrot: at which point are you? | 09:15 |
| chartreuse | For a silly project, just managed to get my hacked copy of the latest PuTTY running on NT4 on Dec Alpha XD | 09:17 |
| chartreuse | Way too much effort for a silly task, but fun to get it done | 09:18 |
| mntmn | yeah i saw, really neat | 09:24 |
| mntmn | does the alpha feel special in any interesting way? | 09:25 |
| chartreuse | It's special in that nothing works on it and is slow by modern standards XD | 09:29 |
| chartreuse | To me it's more using the hardware (My DEC Multia), and the challenge of trying to use it. | 09:30 |
| chartreuse | Like I know it's a failed platform (killed by the mess that was Itanium) but trying to make it work is neat | 09:32 |
| chartreuse | One really neat thing it does have is FX!32 which is a dynamic recompiler that lets you run x86 NT programs on the Alpha, and it works really well | 09:32 |
| chartreuse | I guess in the end, the architecture normally doesn't matter from a user point of view if the software is the same | 09:34 |
| chartreuse | Kinda like being on the Reform here as ARM linux vs x86 linux. It's not really that much different of an experiance | 09:35 |
| mntmn | oh, interesting | 09:47 |
| ex-parrot | mntmn: I have the chroot up, now building the “real system” | 10:24 |
| + erlehmann (~erle@dynamic-046-114-034-172.46.114.pool.telefonica.de) | 10:26 | |
| ex-parrot | has required ~ 1.5 full battery charges to get to this point | 10:28 |
| chartreuse | Are you doing this on the reform? Or something more sensilble for LFS? | 10:28 |
| ex-parrot | On the reform :) on SSD with LUKS | 10:29 |
| chartreuse | Nice | 10:29 |
| ex-parrot | it’s not /terrible/ actually, the worst is gcc which takes about an hour | 10:29 |
| ex-parrot | compared to my work Ryzen machine where it’s more like 4 minutes | 10:29 |
| chartreuse | I think the one time I tried it was in a VM on a Phenom II based system, though that vm could have also been on the previous Athlon XP system... | 10:30 |
| ex-parrot | I haven’t tried in years, last time I kept getting stuck on errors I couldn’t get past. My C building troubleshooting skills have improved a lot since then | 10:30 |
| chartreuse | Putty takes an hour to build on my DEC Multia that I was hacking at | 10:31 |
| ex-parrot | Had to track down a couple of aarch64 related issues etc so far but nothing major | 10:31 |
| chartreuse | I don't remember having issues, but did stop at some point. Might have gotten to the point where I basically now have to compile all the programs I want | 10:31 |
| ex-parrot | things like ls not recognising the host triplet and so not picking the appropriately 64 bit syscall etc | 10:32 |
| chartreuse | But that was because I would have been building on x86 32bit | 10:32 |
| ex-parrot | who would want programs | 10:32 |
| mntmn | haha | 10:32 |
| ex-parrot | when they have a perfectly nice empty Unix in front of them :P | 10:32 |
| chartreuse | Just run busybox and nothing else :P | 10:32 |
| chartreuse | Or better compile emacs and make it your init process XD | 10:32 |
| mntmn | chartreuse: i think i will try && solder some bigger caps on my headphone output today | 10:32 |
| ex-parrot | bash only took a few minutes to build | 10:32 |
| mntmn | but i'll try piggybacking more ceramics first to see how that sounds | 10:33 |
| chartreuse | Ah nice, do use lots of flux as it's fiddly | 10:33 |
| mntmn | ceramic sound probably!! | 10:33 |
| chartreuse | Yeah that might be easier, and less risky that the electrolytics | 10:33 |
| mntmn | i'm just listening to a new album on beyerdynamic headphones and thinking that there should be more bass | 10:33 |
| chartreuse | You probably won't notice much if you're using speakers as they'll have a higher impedence, but do try it with 16-32ohm headphones | 10:33 |
| ex-parrot | what are you listening to, mntmn ? | 10:34 |
| chartreuse | Ah yeah, the stock really is lacking when driving headphones | 10:34 |
| mntmn | just that new NIN-produced halsey thing | 10:34 |
| chartreuse | 47uF is a 220Hz (-3db) high pass filter into 16ohm headphones | 10:34 |
| ex-parrot | ah right, didn’t listen to that yet | 10:34 |
| mntmn | maybe they just did a very bass-less mix but i don't believe it :D | 10:34 |
| ex-parrot | I never understood how electrolytic capacitors can work in an audio output stage | 10:34 |
| mntmn | headphones are dt880 | 10:35 |
| ex-parrot | But it seems to be a thing | 10:35 |
| chartreuse | It is, and most outputs use them, the + side has a dc bias on it so it's always higher than the output | 10:35 |
| mntmn | i have a new audio product now (zz9000ax for amiga) where i use a opamps+electrolytics for the reconstruction filter... i didn't try to connect headphones to that yet though | 10:35 |
| chartreuse | So polarity is less of an issue | 10:35 |
| ex-parrot | Oh right of course | 10:35 |
| ex-parrot | Hah I never considered the bias | 10:36 |
| chartreuse | Even better are bipolar electrolytics for audio dc blocking, they're essentially two caps back to back internally | 10:36 |
| mntmn | i'm still not super experienced with analog though | 10:36 |
| mntmn | chartreuse: interesting | 10:36 |
| chartreuse | So they're much larger that the standard ones | 10:36 |
| ex-parrot | I don’t currently have a machine with Quake set up but I got my NIN quake soundtrack LP out for the 25th anniversary | 10:36 |
| mntmn | ha! i've been eyeing that but don't even have a vinyl player at home | 10:37 |
| ex-parrot | “Quake on Reform” | 10:38 |
| ex-parrot | https://img.hotplate.co.nz/4vsSKdB8 | 10:38 |
| Lewis[m] | Is there an open hardware scene for music related bits? Headphone amps, vinyl players, etc? | 10:38 |
| mntmn | haha nice | 10:38 |
| mntmn | Lewis[m]: good question, i haven't looked much, but there are oshw audio/dsp boards | 10:38 |
| ex-parrot | the “chu moy” and “gainclone” amps were big and kind of de facto open hardware 10ish years ago | 10:39 |
| ex-parrot | I haven’t kept up though | 10:39 |
| ex-parrot | I think hifiberry is one I’ve seen recently | 10:39 |
| chartreuse | mntmn if you double up the 47uF, with 32ohm headphones (which I presume are they beyers you have), that 94uF will give a -3db cutoff of 53Hz | 10:41 |
| chartreuse | Which should be improved a fair bit to the current | 10:41 |
| mntmn | thanks, gonna try that | 10:42 |
| chartreuse | 3 will get you to 35Hz, but that'd be awkward and hard to install | 10:42 |
| chartreuse | I am still happy with my mod of 330uF, and don't want to touch that area anymore incase I mess up and somehow tear a pad XD | 10:43 |
| chartreuse | 330uF is a 15Hz rolloff | 10:44 |
| chartreuse | But doubling or trippling should work | 10:44 |
| ex-parrot | What headphones are you driving? | 10:45 |
| chartreuse | Me or mnt? | 10:45 |
| ex-parrot | You | 10:45 |
| ex-parrot | (Just curious really) | 10:45 |
| chartreuse | The ones I typically use are Sony MDR-XB950's which I'll admit are a bit heavy on bass as it is XD | 10:45 |
| chartreuse | 24ohm impedence | 10:46 |
| ex-parrot | Oh yeah the “extra bass” model :D | 10:46 |
| ex-parrot | I have a friend who swears by them | 10:46 |
| chartreuse | Though with the bass mod it also sounds much better with my KZ-ATE earbuds, and other headphones I tried | 10:46 |
| ex-parrot | I sort of ended up collecting headphones | 10:46 |
| chartreuse | They're great sounding, but could use a little less bass XD | 10:46 |
| ex-parrot | For a while | 10:46 |
| ex-parrot | I’ve had a couple of KZ earbuds but not the ATE I don’t think | 10:47 |
| chartreuse | I think they're all quite similar in sound the KZ's | 10:48 |
| ex-parrot | ACTION kicks off building Perl | 10:48 |
| chartreuse | The most important program | 10:49 |
| ex-parrot | it has a very friendly configure script | 10:49 |
| chartreuse | Just listened to a few of those Halsey songs and yeah they'd sound a bit flat without the bass | 11:00 |
| chartreuse | Though it's kind of an accent in them | 11:00 |
| mntmn | ok time to get some breakfast + head to the lab for some modding | 11:05 |

| mntmn | nice! | 13:30 |
| mntmn | ok added one more pair of 47uFs... | 14:07 |
| mntmn | now it's good ;) | 14:08 |

| mntmn | conky: oh yeah that is true | 21:33 |
| mntmn | it was relabeled | 21:34 |
| conky | Gotcha, thanks for the quick response! | 21:35 |

| conky | I'm looking to boot from an encrypted NVMe. To modify the U-Boot parameters without having to connect to the serial console it looks like I could modify https://source.mnt.re/reform/reform-boundary-uboot/-/blob/bdcdce7434b9db19aabd59181014f24d66af0db8/board/boundary/nitrogen8m_som/nitrogen8m_som.c#L344 and rebuild flash.bin to achieve this, am I | 21:47 |
| conky | understanding this correctly? | 21:47 |
| mntmn | conky: why do you want to change the u-boot parameters? (to what?) | 21:50 |
| conky | mntmn: I was looking at https://mntre.com/reform2/handbook/advanced.html#encrypted-nvme which describes modifying the u-boot parameters, but now I see they are the same as what is already defined in the source there | 21:59 |
| mntmn | conky: yeah it is not necessary except if you want to boot from eMMC->NVMe with no SD card at all | 21:59 |
| conky | mntmn: Got it, thanks | 22:00 |
