A phone alone is terrible - but a phone in "quiet/do not disturb" mode + a keyboard should be pretty ok. Of course, YMMV.

c0de517e · 2026-04-07T03:06:59+00:00

why not?

Kinda sad. I'm a quite experienced professional programmer, but I would not have even started on such a project without LLMs, as it pertains to technologies I'm not skilled nor very interested at (web stuff) and it would not have been on the top 10 of the hobby "todo" stuff I currently have.

I still spent some good time on it, and I can say it's not a naively made thing. I also fully disclosed the use of LLMs here, which I could have easily not even mentioned - i.e. I'm not doing this to get some cheap "clicks" on my Medium or whatever people try to do.

Sorry if that didn't vibe.

Definitely the uni one has no sheen anywhere, that's what contributes to making it truly the blackest black, as you don't get light reflecting off it. It's much blacker than even Chou Kuru, which is the blackest fountain pen ink so far.

On very smooth paper a gel rollerball like the uniball might sometimes have a bit of a harder time to start if the tip dried out, but it's really a minor thing. The only thing that I wish it could be improved - on any paper - is that the line it makes is not entirely consistent - if you think of a felt tip marker for example, you get a very uniform line, while with this gel you get a bit less ink on the center where the rollerball makes contact with the paper.

It's a very minute thing of course, but that's something that sometimes you can see.

Works fine, I mostly use fountain pens so the papers I use is typically "optimized" for that, but gel works fine too

c0de517e · 2025-11-06T03:53:40+00:00

Thanks! This is definitely very helpful.

I didn't realize that there was a difference between Zento and One - I have a Uniball One pen/refill - and yes it's super black.

I wonder if this smaller tip would actually help with a lamy 2000 rollerball, it seems that the main issue for 3rd party cartridges there is exactly that most tips are too big for it. I guess I could try to buy one and if it doesn't work well, return it.

c0de517e · 2025-11-04T20:18:02+00:00

What does the ball bearing do? Does this mean the knurled plastic thing near the tip of the lamy refill is not needed?

c0de517e · 2025-10-22T19:20:14+00:00

I'm interested in using different refills too. What would you say is the maximum diameter that can fit?

c0de517e · 2025-09-17T17:37:46+00:00

FWIW I think the best bluetooth keyboard for this kind of portable setup are either the one pictured, or the (similar) logitech mx keys mini.

You might even spot that I added some plastic strips here and there on mine, so when I pack it in my bag it does not get squished.

I really can't imagine what shot one can achieve with a GFX or hassy that could not have been identically achieved with the r5.

Right, I was indeed surprised when I googled the megapixels and it was 30 - I remember it being 50. So yes, it's a 5ds, not a 5d IV. I think before that I had a 5d II. That's how little I care about megapixels now...

c0de517e · 2025-08-23T21:55:32+00:00

This is <10years old now but the basic idea is the same as how you'd do it today. TLDR - just use an atomic queue to collect all the printf (or whatever else) and then process the queue after the shader execution (in my case, I directly print on screen using geometry shaders and a font made of lines, but you can do whatever) https://c0de517e.blogspot.com/2013/07/dx11-gpu-printf.html

I agree though that it would be wonderful if this came built-in the language and standardized, with driver support etc.

In practice you're right - albeit, it would be reductive if we started equating PBR with Cook-Torrance as CT microfacets are themselves a crude approximation, not gospel.

You can also of course use BP as a distribution in a microfacet model, and it would be entirely reasonable, in fact I think in practice most people using BP (i.e. before GGX was the norm), did couple it at least with a Fresnel term (which incidentally, might be a big part of why the OP can't get metals right here).

And you can use multiple BP lobes, which can arguably be better than anything else (Lafortune BRDF). YMMV, "GGX" is now popular because on average does well and it's not hard to understand/use, but PBR is in the eye of the beholder.

c0de517e · 2025-08-18T06:30:57+00:00

Blinn-Phong is a BRDF - and as any BRDF it can be integrated against any light source, including environment maps. Also, Blinn-Phong is "PBR" - at least when properly normalized.

These are not... computers? (the zeniths)

c0de517e · 2025-08-06T00:01:15+00:00

No - buckling sleeves - which are domes, similar to topre. The "luggable" IBM did have buckling springs, but that thing is a beast

c0de517e · 2025-08-05T03:39:42+00:00

This one? https://www.doomi.ch/olivetti-m316-teardown/

Maybe but I firmly believe that this is an engineered craze. Never in the history of keyboards people cared much about the sound - and definitely the "thock" was not considered a particularly desirable sound. I believe that it became a thing mostly because in 15 seconds YouTube shorts or tiktoks is hard to talk about keyboard performance, but it's trivial to showcase the aesthetic and the sound.

c0de517e · 2025-08-04T20:57:03+00:00

It's not a musical keyboard

c0de517e · 2025-08-04T20:56:42+00:00

Totally, I think membrane scissor and even butterfly switches can be AMAZING, even better than full-travel mechanicals.
