tmjwid··on Magnus Carlsen to give up World Championship title
It is possible to commit no mistakes and still lose. That is not a weakness, that is life.
tmjwid··on Darktable 4.0
For B&W negadoctor is very easy, nothing major with it other than setting white balance, then setting the film base colour and then adjusting D-MIN/D-MAX to the exposure you want. You can then leave it there or go crazy.

Colour is a bit more hands on and with negadoctor you really can get a nice starting base but it's much more manual. You need to make sure colour profiles and white balance match your scaner/dslr scan. The you need to set up the shadow casts and highlight colours. Much more manual just to then get a rather flat image with correct colours to your liking. Then it's more regular raw workflow so altering contrast and saturation but it's nothing too hard still. But it's 100% more hands on the using NLP (this is what I'm assuming you are using. Check YouTube see what you think.

tmjwid··on Life before smartphones (2020)
For me, the idea of needing to fill the time is one of the symptoms of the problem. Empty time is perfectly fine.
tmjwid··on MF DOOM Has Died
This really is hard man, its hit me harder than I'd like to admit. MF DOOM really was one of the greats and it's humbling to see so much love on hn for him.
tmjwid··on RoboScan: Lego+Raspberry Pi-powered analog film roll scanner
That's a great way to work and it is something I think I will do as well. create some presets that give good results then tweak accordingly. Now I just need to get better at colour correcting in the first place!
tmjwid··on RoboScan: Lego+Raspberry Pi-powered analog film roll scanner
Pretty much what scrdhrt has said is spot on. Quality is very much the same, and the output is rather good. I don't have anything to show you from my own work as a comparison, but there is plenty of reference material on reddit and photo blogs about the process.

Time wise, the speed of snapping a photo is also mostly outweighted by the time needed to post process the image (neg invert, white balance, colour correct) versus the slow scanning speed of a flatbed negative scanner. Never used the cheaper 35mm scanners you can buy, but from what I’ve seen they're just the dslr approach without the quality.

I think it comes down to two questions. 1: Do you own a dslr with a macro lens? 2: Do you know how to use raw editors like lightroom or darktable?

If yes to both, then dslr scanning is easily the cheaper of the two and is most likely the best route to go to test the process.

tmjwid··on RoboScan: Lego+Raspberry Pi-powered analog film roll scanner
What a great little project. I find it strange somehow, through the wind, someone always posts a project that relates to me in my current hobbies here on hn. I've just started scanning my 35mm negatives with my dslr (with macro lens) and a film holder on a lightbox. It's easy and much quicker than a dedicated flatbed, but more work post process.

For anyone wanting to do this, you will need to invert your b&w or colour negatives with software capable of processing RAW files (lightroom, darktable, rawtherapee) white balance the negative, invert and then colour/exposure correct the final image. I use darktable for this and the latest version has a real nice plugin called negadoctor that can give you a great starting point. For lightroom, NegativeLabPro is the goto tool and works in a similar way to negadoctor but is better at producing the initial image.

tmjwid··on Reasons to prefer Linux over Windows (2014)
> Although, still some annoying bugs, the most annoying being when I open an application on my 1440p screen, KDE often opens it on my second monitor for no real reason.

This here is my most hated thing about KDE. I run it on Debian so my version is pretty old compared, has it been fixed in newer versions? I have been thinking about switching to Neon, but I don't care for the Ubuntu base verses vanilla Debian.

tmjwid··on Ask HN: Do you still use MongoDB?
Yes

Our use case is dynamic dashboards generation where a document contains multiple components for our frontend to render. Having a simple unstructured database really helps us build the dashboard efficiently. Using a relational database would increase the development time of each dashboard tremendously and having relational integrity would make it even worse.

Having a simple document with everything needed is a much nicer experience. Granted, our use case is very limited and it is read only.

tmjwid··on Dumping MiniDisc Media
Still use my Minidisc almost daily. I prefer older equipment, but boy they're both getting expensive to get discs and tapes. Check out platinum md for a sonicstage replacement
tmjwid··on Making trains run on time
The problem with a single designated exit door is that on super busy trains, if you on the wrong end you'll cause more problems trying to get off through all the people who aren't. Japan has already solved this with a very low tech solution. The right hand side of the door is where people line to to enter, the left hand side is where people exit. As a commuter in the UK that can't remember when my train home was last on time, I find it hard to believe that it's the passenger fault when we are told it's either infrastructure failure or no reason is given.

I've switched to the tram train route that's just opened in Sheffield and that is seeing the same problems. Northern trains running late causing a backlog.

I really miss Japan's rail system.
