[24] Jim Keller Interview 2: AI Hardware on PCIe Cards 

Written version at more-moore.com

Need some AI to clean up the audio.

mic was on the table. i guess he didn't want to clip it on.

universal watermark of brilliance

Lol, yep...

keck xD

Yeah room was filled with whiteboards, and it's just me hauling stuff. Tried to do a lot of AI post processing. I need a proper audio kit for these interviews that I can set up in 5 mins

Oh and now a written version for you: morethanmoore.substack.com/p/interview-with-jim-keller-tenstorrent

@@TechTechPotato You just need a little tripod to get the Rode Wireless Mic as close to the mouth of your talent/subject (I suspect putting a Lav Mic or the wireless Mic on Jim was not possible). No mic in the world can sound good if it is not near the source, unless you want to invest many thousands in shotgun mics and haul huge c-stands and tripods and boom poles around. As an alternative, the "DJI Mic" has better mounting options, you can mount it via magnet so mounting it on clothing is much more easy. And Setup and user experience is an upgrade from the Rode Wireless Go II you are using. IMO, just get some 50$ Rode Lav mics, and wire your subjects up, or just clip the Rode on the chest of your subject. Or as said before, at least put the Mic on a tripod in front of your talent if you can not do that. Proximity to sound source is king in mics.

@@TechTechPotato One or two mics could have been dedicated to delayed remote room audio that would need to be attenuated significantly so that only nearby uncorrelated original voice signal audio remains. The room acts as a filter with frequency group delays and such that produce the noise artifacts that obscure clear reception of the audio. One method would be to focus audio reception from just one of the people and then have a second pass to optimize for the other subject speaker. --> convolution dsp audio delayed echo paths stackexchange The multi-signal path problem is more solvable when you have a fixed geometry and record using multiple microphones. Background echoed audio can then be used to filter sound by means related to one-dimensional convolution with the other signal sources. Around 54 years ago I saw a science fair where a fellow classmate, the son of a polymath genius-level rocket scientist, produced an amazing prefiltered directional mic that employed systemic strategically varying length tubular channels that focused audio upon a parabolic focal situated transducer so that various frequency range noises would be pre-canceled using this elaborate scheme prior to the sound being recorded. Doing an image search using various combinations of keywords seems to fail to produce any meaningful examples that replicated what I had witnessed those many years ago. In prior decades I have seen many science and engineering videos produced that were done recklessly improperly for the ideal image or sound quality. I suppose that each subject and cameraman should be fitted with two lapel mics lest any subject speaker turns their heads from too far to their left or right-hand side. Often the cameraman would be asked to read a digital display reading from a meter and if not microphone-equipped, his response would be much less intelligible. Ambient lighting can also be a cause of low-quality production. The solution for this is to use expensive aspherical lenses that have close to ideal low-light exposure capabilities. --> Stanley Kubrick Zeiss f/0.7 lens candle-lit scenes "barry lyndon" Quotation from website/ The Solution -- Kubrick obsessively researched the problem. He eventually discovered that Nasa had commissioned Carl Zeiss to build ten Planar 50mm f/0.7 stills lenses in the sixties, which were used to take photos of the dark side of the moon. /End website quotation The lower the f/stop value of the given lens, the faster motion could be recorded or lower light situations could be recorded. These various lenses are able to view things in ways many magnitudes better than the human eye. The price of those lenses was many tens of thousands of dollars back in the 1960s, which translates into millions of dollars now. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EUjUxKvXgpw.html Quotation/ Price is the barrier because good lenses cost as much as rare luxury sports cars /End quotation Some sports cars are multi-million dollars so that price really is a barrier until manufacturers can robotically crank out millions of quartz crystal aspherical lenses with very low defect rates, then everyone could buy such stuff.

I love those other channels too, but who else could sit in this room and have meaningful contributions? Maybe Wendell? But really everyone else are consumer facing computer techs, reviewers, overclockers, leakers and tech news repeaters. There's not a huge number of people with either the hardware design/software background to really discuss industry facing topics with the titans working in the field today.

Tom doesn't even belong in the group of those four. Have you seen his reviews? They're a step above RedGamingTech... rofl. He just tells Mfgs he's a reviewer so he can get hardware direct and not wait in line. "puts up token review like he said he would", What a joke. If he did that kind of work as his last employer, no wonder he's out of a job.

Maybe less realize their place and more be inspired by. But yeah I think that's why a lot of people are here, real talk. The last Jim interview was one of the best I've heard and this one was great as well, I end up pausing every couple minutes just to try to properly absorb what's being said and the implications of it. Also I have a feeling a lot of people are severely underestimating how much work Ian is putting into these video's/interviews beforehand.

@@SamanthaVimes177 Wendell might get too excited 😂. Buutt also begs the question, who is this 'guy over there'. I know Wendell has been the camera guy before.

@@Cinnabuns2009 I do take your point, but just remembered Tom also interviewed Jim in his podcast

When will they verify these things on a Raspberry Pi ;)

Sorry if I missed this, but was this recorded before the announcement with Jim and his new company? Is he staying with Tenstorrent?

Ian, you should pin your comment to make it appear on top.

Thank you was looking for the paper the audio wasn’t clear after big ball couldn’t get any relevant search results

@claudyla Atomic Semi is not his new company, its just one he's investing in

Couple weeks ago

I did a lot of audio post-processing, even AI post processing. The room wasn't great. There's a written version if you want to read: morethanmoore.substack.com/p/interview-with-jim-keller-tenstorrent

Yeah unfortunately the room wasn't great, and my audio skills are zero. I did apply some proper post processing on it. If you want a written version, then: morethanmoore.substack.com/p/interview-with-jim-keller-tenstorrent

@@TechTechPotato awesome, kudos!

@@TechTechPotato Just need a close mic for each person and that would cut out a lot of the echo

Doesn't offer a post-processing option. No matter how many times I ask about it. I did use several AI enhancement tools. There's a written version if you prefer: morethanmoore.substack.com/p/interview-with-jim-keller-tenstorrent

@@TechTechPotato Thank you very much.

On that last point - I used to be a world #2 overclocker. My modern laptop BSODs on a weekly basis, which I think is down to the Gen 4 SSD I put in it, which runs at Gen 4 speeds, but clearly the chassis doesn't like it as much. So I think your 'upgrade from Win98' is a bit flippant, especially given plenty of people, deal day in, day out, with systems that like to incorrectly wake from sleep etc.

@@TechTechPotato Yep it was intentionally flippant; I assumed Jim's "all the time" was a bit rhetorical as well. I worked previously as a Windows admin, Win2K era, even then we didn't get random crashes "all the time". Incidents counted per year not week. For our (small company) two Win2K Servers on Dell PowerEdge boxes, zero BSODs ever. Today I manage 3 Win11 PCs in my household, I check event logs and crash dumps, no random crashes. But one problem with crashes is their attribution, the OS gets blamed for everything. For critical and unrecoverable HW errors, the OS is just doing its job when it dies. When it comes to third-party drivers, well Windows is not a clean microkernel system so it can die because of a bad driver for a graphics driver or an SSD. Still rare for me. I share some of your experience with power management issues, but mostly in my MacBookPro, which I run docked with external monitors and KVM-switched and sometimes macOS doesn't like sudden disconnect/reconnect of devices and dies. I don't get that issue in my Windows PC, but I don't have a Windows laptop and when I had one I didn't have this complex docked environment. The Mac is employer-issued, I'd never buy one with my money. For a different perspective, I also use Linux daily: a local Threadripper-based workstation and an EPYC-based cloud VM. Both professionally managed, with WS/Server-class hardware, and without minefields like gaming-oriented GPU drivers. If I discount the crashes that are clearly not Windows's fault, I see no difference in reliability to the Linux systems, they're all extremely solid even though none is perfect. Of course the PC market being what it is, YMMV especially with laptops. The fact is that with consumer PCs, we just expect too much from both HW and SW. We want to pay around $1K for a full desktop machine, choose every component for performance and price, abuse it with BIOS tunings and OC and bad software, reward GPU vendors for biasing drivers for performance at any cost - then we complain that "Windows crashed". :)

Yeah, I want prepared for the environment. There are links to a written version in the description, and I recently uploaded a better audio version, link to that is in the description too

With his jumper it looked like it'd jab into his neck which looks awkward. I did some AI post processing on it to get it this good, but if you prefer a written version, try morethanmoore.substack.com/p/interview-with-jim-keller-tenstorrent

You take what you can get!

Well, everything he said was very understandable.. In this case, PCM Linera audio was not needed.. but it can be improved with a microphone near the table, like a podcast.. 😄

It sounds like Ian has his mic clipped on lapel, but the other mic is sitting on the table relatively close but not super close (so picks up a lot of room noise). Not a lot you can do to clean up the audio in a large four wall space like that. Could maybe improve with a small shotgun pointed directly at talent but Ian might not have had one suitable for the gear he has for mobile recording-sometimes the people you interview aren't comfortable putting on a mic, and you might be at their mercy for the recording.

I turned on closed captions. Helped a lot.

@@JeffGeerling Jeff has it right - with Jim's high collar, it would have looked odd to have a mic jabbing at his neck, so I put it on the table. The end result was a mix of both mics, lots of AI processing. The thing is, if I carry around 2 mics for podcast/table recording, I just know my next interview will be standing up. etc

It the way this guy talks, dude needs to learn how to use his diaphragm

yet 4bit and 8bit microcontrollers are still very popular in embedded electronics. Most of the time, better hardware capabilities are used to ease software development.

To be fair these things tend to have a REALLy long maturation period remember he was gone from AMD years before Ryzen actually hit
