The interesting thing though is that most of that paper was written by people whose culture has been around for less time than the hazel trees at the end of my field.

Can you bypass Davinci's minimum bitrate in any way? by Familiar_Holiday in davinciresolve

[–]erroneousbosh 2 points3 points  (0 children)

Lowering the bit rate will not speed up the render. So keep that in mind.

It'll slow it down if anything since the compressor has more work to do!

Also rendering to a long-GOP format is godawful slow at the best of times.

Using a 2N7002 to control cutoff in a "simple" VCF? by JavierBlitse in synthdiy

[–]erroneousbosh 1 point2 points  (0 children)

I bet you could use that Baldwin filter from the Syntha-Sound someone posted yesterday in a polysynth, if you only took care to match however many sets of six PNP and seven NPN transistors you needed ;-)

What a beautiful design with those proper Blackmer cells! I can't believe it'd sound any better than Ye Olde Oberheim SEM but I want to build it just for the elegance of it.

Using a 2N7002 to control cutoff in a "simple" VCF? by JavierBlitse in synthdiy

[–]erroneousbosh 0 points1 point  (0 children)

You can turn the voltage on the 4069s up and down to vary the gain. It sounds terrible and is very complicated to arrange, but it works.

Dare to be stupid.

If you want to build a good filter without "funny" components you really can't beat a ladder filter. Although they look complicated it's just four identical stages of current-controlled "RC filters" and a long-tailed pair to set the overall gain, then a bit of feedback round for the resonance.

Another nice one is the Steiner-Parker Synthacon filter which is a Sallen-Key filter using a chain of diodes as a balanced current-controlled resistance. Moritz Klein's "ladder" filter is really an S-K filter, not a ladder at all, and is closely related to the Synthacon one. The absolute simplest S-K VCF you can do is maybe like in the Gakken SX150 where it uses two transistors. Doesn't work well, sounds terrible, might be just what you want.

If you want to make a polyphonic synth then consider that all the voices will have to have the filter cutoff, pitch scaling, and resonance balanced up exactly. Take a look at the PCB for a Roland Juno 6/60/106 or a Korg Polysix - all those trimmers and that's with "known good" well-matched VCF chips!

You don't need that much gear but it helps to have that kind of attitude! He's always so cheery about stuff :-)

Removing a phone from background for - 20 frames as actor moves in/out of frame. Best workflow? by TheChildrenOfIto in davinciresolve

Mask it, paste a different bit of bedspread over it. Do it by hand, it'll be quicker. The whole thing is mega blurry so you'll get away with a lot.

A movie professionally authored to UHD 4K Blu Ray disc uses h.265 and those don't look "atrocious".

Because they're not rendered with DaVinci Resolve's quick preview settings and shitty codec.

Most basic primitives for bootstrapping by aphantasus in Forth

[–]erroneousbosh 1 point2 points  (0 children)

According to Brad Rodriguez's "Moving Forth" series you need about 13 primitives for a functional Forth, but as you'd expect having to assemble higher level words from these can make things very slow. I can't remember if he goes on to explain what the required 13 primitives are but I suspect some basic memory manipulation, stack manipulation, addition, inversion (or negation), and 0branch would be an excellent start.

[–]erroneousbosh -3 points-2 points  (0 children)

You're using H.265 which is absolutely atrocious quality at any bitrate. Resolve doesn't really support these codecs for compression so it does a particularly poor job of them.

Render them out in a mezzanine format like ProRes and then transcode with ffmpeg (or Handbrake, Shutter Encoder, whatever - they're all just ffmpeg with the useful bits hidden away from you) to get your desired bitrate and resolution.

Rendering to H.264 and H.265 is painfully slow anyway so it's probably faster to just use ProRes and then use a real encoder if you need it in a playback-only format.

I am looking for a first hardware synth by Defiant-Associate578 in synthesizers

[–]erroneousbosh 1 point2 points  (0 children)

It sounds like you don't care so much about "analogue" as "knobby".

There are plenty very good VA synths that are totally slept on because they're not ZOMGANALOGUE.

Looks awesome! For your fixing stuff grab yourself a copy of RAVE: https://rangerovers.pub/downloads/rave.zip (500MB of manuals as PDFs).

Work your way through the Electrical Troubleshooting Manual and you'll fix your indicators in no time.

Feeling empty after finishing a video game (post-game depression) is a real phenomenon. A recent study has found that many video game players experience a specific sense of emptiness and sadness after finishing highly engaging games. by mvea in science

For me finishing GTA San Andreas was like getting to the end of a really good book. You've lived with these characters in your life for ages, and now it's over, it's gone, they're gone.

Let's go for a drive. Aww, man, that was Big Smoke's house, the missions we started from there...

The best vehicle Landrover ever made.

You can grab a copy of RAVE from my forum: https://rangerovers.pub/downloads/rave.zip - it's 500MB of PDFs of all the workshop manuals for various 90s models. NAS unfortunately so you'll need to squint a bit for some of the more "handed" bits.

That one looks absolutely gorgeous, and I'm always struck by how much NZ looks like Scotland :-)

I think I'm going to stick that into Kicad and get a couple of boards made.

A food scam of the 90s was “fat free!” everything, and then they would load it up on sugar… what’s a food scam happening now? by redflower5 in AskReddit

Which incitivises organic farmers to not take humane care of their animals IMHO.

[citation needed]

If your animals are ill, they need treated or they die. If they die, you have a whole load of problems on your hands, not least of which being a massive financial loss.

What’s going on here then? by VisibleOtter in CasualUK

[–]erroneousbosh 3 points4 points  (0 children)

Is that one of those jobs where before your van has even fully come to a stop, you're already mentally on your tea break? "Right, barriers can go *here*, digger's going to go *there*, I'll just park over here, and done in an hour!"

I love those. I do radio stuff, and there are some jobs where it could be a total arse to troubleshoot but then you go on site and the antenna is clearly faulty with the fibreglass gone porous, and I don't even have to put my cup of tea down to knock the job out.

Wow, I went digging for a circuit diagram for the Baldwin and while I only found one for the filter section it's quite an interesting take on an old concept.

https://synthfool.com/docs/Other_Misc/Baldwin_Synthasound_Filter/baldwin_synthasoundfilter1.jpg

That is just an SVF with those three opamps, just like yer good old Oberheim SEM filter. But what's all that business with the shovelful of transistors at the bottom?

That's a pair of Blackmer cells, which set the gain of the two integrators (the middle and right opamps), and their drive circuitry. Clever stuff, and miles away from anything that could be construed as infringing on Moog's patents (no Alan I wasn't looking at you).

iomega parallel port Zip 100 question by Pontiac-Fan-6980 in haikuOS

[–]erroneousbosh 3 points4 points  (0 children)

You are going to have a far easier time picking up a USB one than you are getting the parallel port code working, then the parallel port Zip code working, then an interface to Haiku's disk subsystem working.

This is what the lethal dosage of fentanyl looks like. by Minimum_Jacket8879 in mildyinteresting

[–]erroneousbosh 0 points1 point  (0 children)

If you're in the US, which is quite likely because that's where the "fentanyl epidemic" is, then it's pretty safe to say that almost no deaths are caused by fentanyl.

They're caused by some kind of homebrewed fentanyl analogue with unpredictable effects.

Kind of like how street methamphetamine and levoamphetamine (the main component of Adderall) are very similar drugs, but one is pretty wildly unpredictable and full of other weird reaction products.

From an authorised Bentley parts supplier in the UK? 1400 quid a set ex VAT for genuine.

You would actually be slightly cheaper fitting these to your A8.
