I achieve something similar with the following function in ~/.jq

  def flatten_tree: [leaf_paths as $path | {"key":$path | join("."), "value": getpath($path)}] | from_entries;
e.g.
  curl -s http://consul.service.consul:8500/v1/catalog/service/brilliant-service | jq -r 'flatten_tree'
I haven't felt the need to devise the reverse transformation yet, but it works great for grepping blobs of unknown structure

The title directly contradicts an article that appeared recently in the Guardian [1] (although as you say the title hardly seems appropriate given the content of the article)

A slightly better summary can be found at [2] which explains the differences better (i.e. moderate drinking lowers risk of dementia and heard disease, but increases the chance of e.g. accidents)

\begin{equation} ... \end{equation}. Finding modern resources to learn LaTeX (and indeed TeX for macros etc) has been a perennial difficulty for me!

I have used them in the past to convert graphs and reports to JPGs and PDFs so that I can automatically email them to people in the company who are unable (or unwilling) to use a web page.

The tunnels themselves can be full size (which is good for reduction of boundary layer effects) but the models are typically 60%. There do exist some 50% models for cost reasons, but the correlation is worse and there are problems like the pirelli-supplied model tyres (amongst many other things) tend to be a bit crap.

Mostly tried to bring some kind of rigour to the process of deciding strategies. The majority of the day job was spent persuading people that spreadsheets are not the way forward and implementing stuff in python with web front ends. I think most people would be shocked at how non-cutting edge the software is across the industry!

Working during the races were fun when there was a genuine decision to be made however!

In CAD they manifest themselves as a bunch of boxes in which you are allowed to put your shapes, so it's not overly taxing for the engineers to follow. However there is a risk that the 'box' layer is not done correctly at the beginning of the season and you end up missing something important.

The limit on computing power encourages you to think more carefully about what a certain component is interacting with the rest of the car. A few years ago I remember a CFD engineer running a massive DoE with hundreds of cases to get his stats up for the week when there was spare capacity in the cluster. If the limit were removed I doubt there would be any increase in innovation, just way more carpet bombing with parametric designs.

While DRS may seem artificial, it may pay to re-watch Alonso's race in Abu Dhabi in 2010 where he was stuck behind a much slower car for what seemed like the entire race.

With the heavy reliance on aerodynamics and the issues with a car losing downforce in the wake of the one in front, you can view is as compensation for that effect and (if you stretch your imagination somewhat) closer to the pre-aero days of racing.

Since DRS has been introduced however, the number of overtakes in each race is steadily decreasing, so you may see a more radical solution in years to come. I personally would like to see wing-aero substantially reduced and grip / tyre size increased to compensate, but the massive investments in tech and people and aero's tendency to make the whole process mean-reverting make it a strongly vested interest for the top teams.

As an ex-F1 Strategist without the data that I'm used to when watching races, I find this incredibly frustrating. The FIA is the source of any data that teams have about their competitors and this could very easily be forwarded on to the broadcasters. Given that the ownership of F1 has changed recently, there is a chance that this will be opened up at some point in the future.

FWIW, I think that if broadcasters do manage to get their hands on the live timing in a numerical format (rather than on a TV screen) you could see them extracting more interesting stuff than the teams do themselves!
