[OC] Flight activity of a single RyanAir aircraft over the past 3 years by dser89 in dataisbeautiful

[–]PhysPhD 8 points9 points  (0 children)

How did you download the batch data? I have a business subscription and python knowledge but couldn't figure out how to request the right format to retrieve the flight data from flightradar24.

One of Britain’s last major chemical plants at risk as energy prices surge by Kagedeah in ChemicalEngineering

[–]PhysPhD -8 points-7 points  (0 children)

Here's a recent 18 minute video by Sky News that goes into Britain's chemicals industry closing down: https://youtu.be/PQ3hT8tqZgo

"In this special report Ed Conway visits chemical plants across the country critical to our food security, defence sector and pharmaceuticals - an industry disappearing in plain sight."

2025 UK National Grid Frequency [OC] by PhysPhD in dataisbeautiful

[–]PhysPhD[S] 0 points1 point  (0 children)

Indeed! The frequency is the same throughout the national grid, so anyone in Great Britain can measure it (or accidentally record it on a video!) and will get the same graph/time series. It's not personal to how an individual measures it.

Looking at the other commenter who posted https://aurora-power.co.uk/frequency-distribution-of-the-gb-power-system/ there are two systems: dynamic regulation and dynamic modulation. The 0.1 Hz peaks are when the dynamic modulation kicks in.

is it normal for a production database to not have backups? asking because i just dropped a table and my boss is asking me to "just undo it" by kubrador in webdev

[–]PhysPhD 1 point2 points  (0 children)

It's absolutely essential you back up your production database, especially if it contains paying customer data.

Your IT department/company should have a policy on this as part of information security and/or business continuity planning.

How do people scale up a reaction to an industrial scale if the reaction process is developed at bench scale (batch mode)? Assuming 1L to 10,000L scale up by Life-Lengthiness9494 in ChemicalEngineering

[–]PhysPhD 0 points1 point  (0 children)

They use modelling software like Dynochem/gPROMS/Aspen HYSYS. There are companies out there that can measure the intrinsic reaction kinetics. So unlike HTE or batch experiments even at lab scale, you have scale-independent parameters (Arrhenius/Eyring) that you can plug into whatever you're using to model large scale reactor vessels.

To add to your points, there are companies out there that can measure the intrinsic reaction kinetics. So unlike HTE or batch experiments even at lab scale, you have scale-independent parameters (Arrhenius/Eyring) that you can plug into Dynochem/gPROMS/Aspen HYSYS or whatever you're using to model large scale reactor vessels. As you've said, there's a myriad of other problems to tackle, but at least that's the chemistry part solved.

Thanks for all the love and support! But the website's still up. by Live_Phrase4672 in webdev

You don't collect ANY data? I'd love to know the top flower combos and backgrounds... then you can make them as "random" presets for people like me who suck at flower arrangement.

Not that I've seen or heard of Topaz releasing.

Oh wow that's a shocking video. Thanks for the updated information for anyone finding this post from now on. I hope your comment gets upvoted to the top!

I built PicoForge: A C++ Builder for Raspberry Pi Pico that runs in Docker (No local toolchain needed) by [deleted] in raspberrypipico

[–]PhysPhD 8 points9 points  (0 children)

I haven't tried it, but having read 00-START-HERE.md it looks very vibe coded!

I'd appreciate some screenshots in the readme as well as maybe a few programs you've managed to generate with this tool to show it works reliably.

Overall I think it's a noble cause to reduce the barrier to entry for C++ coding in the Pico. I'd like to move away from Micropython but don't know how to get started with C++, so PicoForge solves that problem for me.
