I work in the borehole instrumentation industry, and lots of our customers get hyperspectral data from core. I'm working on a new data delivery and management platform, and I've made sure our data structures can handle hyperspectral images. Multidimensional arrays are front and centre. I too think of spectral images as "cubes".

One thing that stems from this is the question of how you visualise it. False colour mapping?


I found that people think that whatever you are doing must be extremely cool if you display it with the 3rd dimension being time. So create a video of each frame of the hyperspectral image and it shifts from one frame to another. Idk if it is super useful but if you put the video on a powerpoint it gets lots of excitement

Photoshoplayers with color overlay or alpha shift towards the selected layer against a dark background ?

Oof, that's tough. I'm over here on a blue card, and I found that the initial application and dealing with department of immigration was actually really streamlined. Everything is very manual and personal over here, but there are a large number of public servants that are very welcoming and happy to help out.

I've noticed the umami flavour that tends to develop when cooking beer for a long time. An Irish stew with Guinness in it, or a gulas using beer as the staple liquid all develop Vegemite like flavours.

I love it, but I think a lot of non-Aussies don't recognise the similarities.


if you haven't done it, try slowly concentrating guinness in the way you would concentrate stock. Then add a little meat juice. It makes a formidable sauce.


Thank you for the idea!


For those that aren't aware, it's a free conference focusing on all things open source - https://fosdem.org/2024/


I'd like to add, fosdem talks can be viewed realtime online via the web site or on matrix. Video's will also be published after the conference.


Not an actual live feed. It looks like the launch will be soon. Official details can be found here: https://www.spacex.com/launches/mission/?missionId=starship-...


It said live feed when I posted and had a countdown timer. There is no way I am going to create an X account for watching it...


In another thread, someone posted this alternative transmission https://www.youtube.com/watch?v=uOI35G7cP7o by NASASpaceflight (that is not an oficial NASA source).


Thanks. Maybe the Mods can update the link.


There are multiple official camping grounds and caravan parks on the route. Unfortunately wild camping isn't allowed anywhere. I know that some people still try it, and probably so long as you're somewhere off trail, camp late and leave early nobody will bother you.


A few months back I dragged myself away from Tears of the Kingdom and went on a four day hike across the entirety of Luxembourg.

I planned my route using open source GIS tools, and did the cross country walk over a long weekend back in June.


I see you used QGis. Last time I tried it there was no easy way of plugging a router. I switched to QMapShack. It's a bit more complicated to use the IGN service for the maps (whereas it works out of the box with QGis) but there are several options for routers. The offline one (Routino) requires downloading data but it works well. I use it all the time to plan 2-5 days treks in the French Alps. Having the actual elevation profile for a given segment is really useful.

Just thought you might want to try this setup for your next trek!


Thanks for the recommendation. I used KML files and manually connected them, but a router would've been handy. I'll give it a shot.


It's why I switched my Model 3 to just report battery percentage instead of estimated range. Their charge usage algorithm in their route planner is very impressive. Even across 300+ km trips, I've never seen it out by more than a few percent. From what I can see, it's most affected by wind. I guess they don't input weather into the estimation model.

My experience is that real world usage gets me about 85% of the advertised range for most of the year. I average around 160 Wh/km for the driving I do, so with a pack capacity of 75 kWh, that's about 470 km. Advertised range here in the EU was 530 km.

I post pretty sporadically about things I'm working on or that interest me. Electronics, coding, food, general hacking and making.

There are only a handful of posts there now, with 2 or 3 in the pipeline for the coming months.


Author here. This is just a bit of technical discussion on the first bring-up and testing of a new design of force/torque sensor that utilises a Stewart platform geometry. The ultimate goal is that it'll become a fully functional SpaceMouse style device, which at the moment are really only available from one manufacturer due to many mergers and acquisitions and some heavy patent enforcement.

I've released the design open-source, so if anyone is interested in contributing, check out the GitHub repository. Let me know if there are any questions or feedback.
