"Collaborative CAD in JupyterLab". Check out our latest blog post about JupyterCAD, the collaborative CAD modeler for JupyterLab. blog.jupyter.org/collaborative-… @ProjectJupyter @FreeCADNews
Remembering Terry Pratchett today on what would have been his 75th Birthday. It is still hard to believe that my greatest source of creative inspiration is no longer with us, thankfully his legacy remains for us all to enjoy.
Super pleased that our paper on BNN coupling in acoustic metasurfaces has been published in Physics Rev B. Massive thank you to @GChaplain and my PhD supervisors #acoustics #metamaterials journals.aps.org/prb/abstract/1…
@engineers_feed The problem as described is ill-posed. As the conveyor belt speeds up, it will increase the speed of the wheels, so the two will never be equal. Unless you think wheel friction could overcome engine thrust.
@lukeweston I remember a lot of uproar about the "terminator genes" in Monsanto seeds that would prevent farmers planting the seeds from their own crops. I vaguely recall announcements of that being cancelled. Maybe activists moved on at that point?
@r1cc4rd0 So true! I get triggered when I see line graphs that have jpeg compression artefacts in them!
You can look at it endlessly! #ua9ytp #hamradio #hamr #amateurrardio
@lukeweston How many times will you need to sputter coat it to get full surface coverage? I guess there are some parts on the outside that don't matter.
Little 3D printed horn antenna. Gonna sputter coat it.
Previously unpublished photos from my personal archive. Simferopol, Crimea, Ukraine. March 9, 2014. Nine years ago. This was our last protest against annexation. On the next day, organizers were kidnapped by FSB. I wonder where all those people are now. What is their fate...
It's almost 6 a.m. in Ukraine, and it's a massive rocket strike again. It goes wave by wave, so I can't go to bed. It's important to follow the news and listen to the outside situation. I decided to use this air alert time and reverse engineer something.
@lukeweston Although legal in Australia, cannabis is still still not a recognised treatment for any condition. So none of the usual rules around pharmaceuticals apply, and conflict of interest seems to be rife. abc.net.au/radionational/…
@Orad Fair enough, but the question remains - how useful would this average be? A far more useful statement might be that 95% of devices have losses of x dB or less. Beyond that I would look at the distribution on both log and linear scales.
The KiCad project is proud to announce the first major release since version 6 was release just over a year ago. Version 7.0.0 has officially been released and is available for download. kicad.org/blog/2023/02/V…
@lukeweston Anyone over 40 is eligible for a 4th dose, so not that limited a cohort. Not sure if they've expanded it since.
@schmidtim @QuinnBesford Those flags you mentioned gave quite generic designs, but PNG flag is quite distinctive upload.wikimedia.org/wikipedia/comm…
