gripfx··on Nexphone: Android phone also runs Windows and Linux
From the same makers as Nexdock, a phone running Android that dual boots into Windows
gripfx··on Open Banking and Payments Competition
I use the GoCardless API to pull transactions and balances into a Google Sheet. They have pretty good coverage for UK and EU it looks like [1]

gripfx··on Vice website is shutting down
Not everything on Vice was great but I will always be grateful for them introducing me to the Joel Golby and his London Rental Opportunity of the Week column[0].

gripfx··on Analyzing Spotify Stream History
I have been using last.fm[1] for this for years (just checked, from 2008!). They now do a rolling weekly and annual interactive chart which is fun to look at, here's mine for 2023[2].

They have a Spotify integration and I use PanoScrobbler on mobile.

Is it iSyncr + Rocket Player? I am in the same boat if so. Have the paid versions and don't see ads at the moment, but the "Rate Me" popups are a bad sign.

gripfx··on Ask HN: Please Dark Mode for HN
I have been using the Svelte clone of HN [0] when needing dark mode. It has a toggle for dark/light and is relatively quick to use.

gripfx··on 2021 Williams F1 Computational Fluid Dynamics
That was awhile back. The rules have since been updated to be more flexible. AMD now has a multi-year partnership with Mercedes F1
gripfx··on 2021 Williams F1 Computational Fluid Dynamics
Each team has to submit an audit of CFD runs at 8 week intervals throughout the year. An FIA inspector can also turn up on premise to review simulations run. The full details are in Appendix 8 of the sporting regulations [0].

gripfx··on 2021 Williams F1 Computational Fluid Dynamics
As someone in the industry, please take these numbers with the biggest grain of salt you can find. The writer has both added their own components and not divulged the CFD settings used. Which is fair enough but the numbers shown could be within 10% or 1000% percent of a "ballpark".

gripfx··on HN Alternative UIs
For those looking for a relatively fast, mobile and dark mode friendly reader for HN, my pick is https://hn.svelte.dev/

It is made with the Svelte JS framework

gripfx··on Turns out half the internet has a single-point-of-failure called “Cloudflare”
On an unrelated note. Thank you so much for PortableApps.com! It was invaluable at university when studying in the library. To this day, I still use it for utilities that don't need to be installed on my desktop.
gripfx··on Formula 1 2020: The secret aerodynamicist – are capes the key?
Those numbers are pretty generous, I would beg to differ on at least some of them. [1][2][3]

My mistake when you mentioned ground effect, I thought you meant sealed (skirts and fans). The ground effect you mean is already a thing in present F1 thanks to diffusers. The new rules have just made the diffuser bigger and simplified the front and rear wings.

gripfx··on Formula 1 2020: The secret aerodynamicist – are capes the key?
That is an interesting question. For me personally, no, not at my current life situation. For the most part, teams are subsidiaries of larger corporations and there is a little bit of security there. The privateer teams other than that pose some job security risk but most staff are highly skilled (normally to a post graduate level) and would be no different than joining a startup which might go bust at the end of runway.
gripfx··on Formula 1 2020: The secret aerodynamicist – are capes the key?
It is neither. All teams big or small use a wind tunnel. Simulation and regulation limits on computation mean that a virtual only development program is impossible. Virgin Racing tried it a while back and flopped completely. What some teams do though is use outside wind tunnels owned by others, like another team or Toyota Motorsport in Germany
gripfx··on Formula 1 2020: The secret aerodynamicist – are capes the key?
I would be very surprised if Haas is spending anywhere close to the incoming budget cap. They arguably have the smallest expenditure thanks to the Ferrari parts deal and contracting the chassis out to Dallara. Of the current teams, I think only Mercedes, Ferrari, Red Bull and Mclaren (by a much smaller margin) are spending above the incoming cap.

Sealed ground effect will probably not return to F1, not for performance reasons but safety. Introducing the seal greatly increases downforce but once it is broken, the dropoff is incredible. Maintaining that would be nearly impossible with surface imperfections and debris on the track.

gripfx··on Formula 1 2020: The secret aerodynamicist – are capes the key?
Sure. The role (and myself) are in the aerodynamics department, developing and maintaining software for the aerodynamicists. The role of the aerodynamicist is to develop the bodywork of the car (wings, ducts, chassis shape etc) to improve aerodynamic efficiency. This is done primarily in computational fluid dynamics simulations [1] (virtual) and scale model testing in a wind tunnel [2] (physical) before being tested on the actual race car. My group works on the software to analyse the data output. Think data science dashboards with lots of real time and historical data. Due to our requirements, the tools are designed in house with input from users. In my time here I have worked on interfacing with the HPC cluster, improving visualisations and improving our backend stack amongst other things.

For your last question, it is a bit of both. I went to university with the goal of working in F1 and the competitive aspect is definitely there but as I was not a comp sci student the technical problems are still interesting. Developing aero is very visual heavy as ideas are implemented as 3D CAD designs and often reviewed as such. So it's not just a more complicated stock ticker that needs to be shown.

If anyone is interested, the software team I work for is hiring! F1 is definitely an interesting challenge and a unique work environment.

gripfx··on When His SR-71 Blackbird Disintegrated, This Pilot Free Fell from Space
The CFD simulation in F1 isn't really a track simulation. Normally a straight or curved domain (for car in yaw) is used. Computational limits in the rules mean simulating dirty air, like when following a car, is incredibly inefficient.
gripfx··on Show HN: Festival Hunt – Discover, filter and sort music festivals
IIRC bands that you track are in bold on an events page. No predictions on who you should see though, that's probably out of their wheelhouse. I do think they have some kind of API acces to ticketing sites though because more than once the emails I get had working links to artist presale that I could use. Another app that I use is Dice. Not sure what the avaibility is outside of the UK but I have got (relevant) suggested events based on other tickets I bought from them.
gripfx··on Show HN: Festival Hunt – Discover, filter and sort music festivals
Songkick does exactly this. Links with various music and social media accounts, then matches concerts and festivals in areas that you specify. Whenever a concert is announced by an artist I listen to in a city I have selected, I get an email with details on where and when tickets are on sale.
