Arthur Brainville @ybalrid.info · 14/09/2026In a very long list of useless things I am playing with right now, it seems that NTP does it's job... And my rube goldberg machine of raspbery Pis and ATAs do not add that much latency Dialing NIST Colorado's time service here, from France, the clock pulse is basically in sync with this computer 000
Arthur Brainville @ybalrid.info · 12/03/2026ISO of (BW, for simplicity) film is determined by computing how much exposure is required to achieve recorded density in the shadows at a specific rate of development I do not have a sensitometer, so I use my enlarger and a step wedge: but here's my test of Kentmere 200 (found 182, close enough!) 100

Arthur Brainville @ybalrid.info · 09/03/2026How can it take 5 days to remove an email address from a list, for a company that its sole product is basically A FRONTEND FOR A DATABASE FULL OF TASKS 000
Arthur Brainville @ybalrid.info · 08/03/2026With the caveat that this is the THC used for Canadarm2, This is an analog device! 110
Arthur Brainville @ybalrid.info · 03/03/2026Fun tidbit, Canadarm uses the same input method, as demonstrated here by JAXA Astronaut Wakata Koichi 100
Arthur Brainville @ybalrid.info · 03/03/2026Maybe I am missing something, but I cannot find a good replica or a good analog of this input device on the space shuttle's cockpit that can be just used on a computer. It is called the THC: Translation Hand Controller, and is a 3 DoF device used for... Well, translation control in space! 100
Arthur Brainville @ybalrid.info · 16/02/2026The full Vulkan specification in its latest version with all extensions is a small 6884 pages, as a PDF (most of it is the description of data structures and function calls, but the first few chapters actually are explanatory) 010
Arthur Brainville @ybalrid.info · 12/02/2026I have downloaded the demo of Kittens Space Agency. Need to spend a little bit of time with this, but as far as a "spiritual successor to KSP", I think they're really getting somewhere here. Loading the solar system (apparently the whole thing) destroyed my 3080 10GB I got in 2020 110
Arthur Brainville @ybalrid.info · 10/02/2026You will generally see a blurb like this in the docs for each function 010
Arthur Brainville @ybalrid.info · 08/02/2026This is a modern retro-looking flash. It works stupidly well design-wise on this 1960’s rangefinder camera! 001

Arthur Brainville @ybalrid.info · 24/01/2026ChatGPT was doing fairly well at attempting to reconstruct a STL file form Gcode, analysing the extrusion commands to build cylinders, then fitting voxels inside.... But then it decided that it needed to check that 1+1 = 2 000
Arthur Brainville @ybalrid.info · 09/01/2026The fact that Outlook for Windows needs to display this banner is really a sign that Outlook for Windows is very very well integrated with the other small Microsoft product called... "Windows" ... 010
Arthur Brainville @ybalrid.info · 30/11/2025Going to spend a few drops of it to ask Waterman France why did this happen and also to encourage them to reintroduce this product on the market. Mostly for the bit. But I would be surprised if they don’t respond! (Yes, this bottle is about 10 years old - so it’s not the newer blue label) 180
Arthur Brainville @ybalrid.info · 03/11/2025I promised film scans, here there are: This is no alternative to Ektachrome. Kodak might be unintentionally making a pretty acceptable 50 ISO tungsten balanced "lower" contrast and saturation slide film (with some amount of magenta/green shift) Again, it's a negative film for planes 110
Arthur Brainville @ybalrid.info · 02/11/2025E-6 Cross processed Kodak Aerocolor IV (REFLX Pro 100 in this case. It's same film as SantaColor 100 and Elektra 100. Probably other rebrand exist) Rating it EI 50 (so, box speed +1EV), 85B warming + Skylight 1A filters. This looks too good to be a hack, like WTF? Will do real scans later... 110
Arthur Brainville @ybalrid.info · 25/10/2025Searching stuff inside the scan of a old paper from 1922. The OCR that was used on the PDF read the greek letter gamma (γ) as a 7. Which is slightly annoying when this is a paper about sensitometry. (Interestingly they use a geometric method of obtaining the gamma, not the analytical one) 000
Arthur Brainville @ybalrid.info · 18/06/2025I really really this image to be softer contrast. To illustrate, here’s a digitally made inversion of the above picture Retaining the highlights and getting shadow details exposed and developed are the 2 things that should allow getting more of the tonal range of the slide expressed on paper. 110
Arthur Brainville @ybalrid.info · 18/06/2025This is the negative exposure developed. It kinda looks like if this was film, was pushed many many stops. Maybe this result is effectively a low exposure over developed. It’s really hard to know. Also this grey-ish thing is the maximum silver density on this color paper developed in BW 110
Arthur Brainville @ybalrid.info · 15/06/2025All the test prints. First few are too blue. I need to think about which of the 3 ways of reducing contrast I should try to test first. (May need all three of them combined) 010
Arthur Brainville @ybalrid.info · 15/06/2025This is a scan of the slide. You can see there is a lot of dynamic range lost on the printing process. I have 3 things I can attempt: - use a low contrast BW developer as 1st dev before reversal exposure - pre-flash the paper - retard color development with sodium sulfite 310
Arthur Brainville @ybalrid.info · 15/06/2025This is a very first attempt of doing RA-4 reversal printing from one ektachrome frame. I simply used ILFORD Multigrade black and white developer as 1st developer and just waved the print for a minute I for of a light before color development though the normal RA-4 process. Need lower contrast 130
Arthur Brainville @ybalrid.info · 06/06/2025Businesses, you do not need to put this bullshit in the footer of your emails. This is not going to fix climate change 000
Arthur Brainville @ybalrid.info · 05/06/2025I may actually write a blerb about this maybe on my mostly abandoned blog A rarely documented online cause of shutter failure for Canon A-series (here AE-1 Program) cameras is the "SW4 Count Switch" not actually closing after the 1st curtain latch is armed if it's dirty, or corroded (or both) 130

Arthur Brainville @ybalrid.info · 16/05/2025Wikipedia et Wikidata ne sont pas d'accord sur la date et le lieu de naissance d'Émilie du Châtelet! Qui donc croire sur quand et où est née la traductrice du Pricipia Matematica de Newton (et amie de Voltaire)! 100

Arthur Brainville @ybalrid.info · 20/02/2025A few straight RA-4 darkroom prints of @harmanphoto.co.uk Phoenix 200 on Fuji crystal archive paper Lack of orange mask and purple-ish base are non-issue. Just do test strips. Had to filter out a lot of yellow interestingly. It is just different than Kodak/fuji but it works just fine. 270

Arthur Brainville @ybalrid.info · 19/02/2025Mine is an older Zorki 4 (non K) from 1963 and it’s setup with the before-mentioned Jupiter 9 and a 85mm finder! 110
Arthur Brainville @ybalrid.info · 17/02/2025If anybody is curious, this is the color of Fujicolor Crystal Archive Photo Paper. The cyan is an anti halation dye. You are not supposed to see this but apparently this 4x5 sheet was out when I turned the lights on so now it’s ruined lol. 000

Arthur Brainville @ybalrid.info · 06/02/2025Made the mistake of trusting the Godox Lux Master flash’s auto mode (wich does not work as good as actual vintage thyristor flashes it seems😕), I have under exposed some ektachorme by a bit more than a stop or two. But, despite how dense the actual film is, the result scanned relatively well 220
Arthur Brainville @ybalrid.info · 06/02/2025Canceling a Chess dot com subscription is a 5 page form of surveys with the big highlighted button being "keep my subscription" Annoying, and somewhat dark pattern-ish. That would already be bad. But also it just does not work, it results in a server error. 100
Arthur Brainville @ybalrid.info · 24/01/2025@nileane.fr as far as EDC goes, I am French, and - granted I work from home and I generally don’t bring it out with me in town - I have a Swiss Army Knife handy at almost all times. A Victorinox Deluxe Tinker. Great Pliers and scissors integrated in that. This one is a gift from my mom! 010

Arthur Brainville @ybalrid.info · 03/01/2025With keeping the chems in collapsible bottles, with no oxygen, in a cool place, a Bellini C41 kit I mixed mid October is working fine today, and has processed quite a bit of film already, probably more than half way through the capacity. If you ask Bellini, these chemicals should be dead by now 000

Arthur Brainville @ybalrid.info · 27/12/2024A Canon Speedlite 540EZ on a EOS 650 looks slightly ridiculously big. (It is quite heavy at the very least) It was an eBay bargain. But I need to look for a A-TTL (so, film era EOS) canon flash that also has a movable head for bounce flash that is not that stupidly big maybe. 010
Arthur Brainville @ybalrid.info · 23/12/2024Also exchanged a few parts from a broken one in better cosmetic shape onto this body 100
