Όποτε υπάρχει κάποια είδηση με ισραηλινούς πολίτες αναφέρεται συνομοτικά εν είδη βαθύτερης εξήγησης "είχαν υπηρετήσει στον IDF" - λες και σε ανάλογη περίπτωση στην Ελλάδα (ή στην Ελβετία) το 99% των αντρών δεν θα είχαν υπηρετήσει στο στρατό (αυτό είναι ο IDF, όχι οι GIJOE..)

A true successor to XL1 and a great concept by VW. This is a prototype but 90% of what is shown and ~90% of its performance can be applied to a production car priced as an id.3. The "Mission Efficiency" use the drivetrain and battery of id.Polo, Cd 0.158 and 6.89 kWh/100 km

"the Cybercab is extremely spacious for a small car" Cybercab looks roomy for two people, but look at the other photo, it is the interior of a shorter car, with room for 7 (let alone 2 or 4!), a car that also houses a diesel engine / drivetrain and was designed 40+ years ago

I haven't seen anything by Nathan Fielder, that wasn't at least good, what he makes is usually profound and occasionally transformative. The only problem with his work is that you cannot explain why it is so good to people that have not see it. ex: youtu.be/r3-Y31ONZuI?...

Bristol cars, under new ownership, will finish 5 unbuilt fighters (sold under IVA) with plans to resume regular production again under -hopefully!- the same values of the original Bristol. At £235,000 these "new" fighters will be a bargain www.autocar.co.uk/car-news/new...

I saw the movie Hackers for the first time, ~30 years after its premiere. It is super cringe even for 1995, and easy to make fun of, but it is a genuine artifact of a time that people feel too superior to even acknowledge. *some stuff really resonate with today's world :

F1 was mainly a Gordon Murray project, but the input of Peter Stephens, Ron Dennis and even Mansour Ojjeh made it what it was. T50 is similar but quite a departure in many ways. S1/LM looks cool, better than the T50, but not better than the F1 (despite the 34 years gap!)

Hot take: this is *a* solution but not *the* solution, topology optimised structures like these may be good (like this Czinger) or bad. People treat them as THE optimum solution, it's not, in most cases you can visually see that there is material (or lack of) in the wrong places

Gallardo & Murcielago are two of the best looking Lamborghinis ever. Luc Donkerwolke really was a worthy Gandini successor. He said that working for Lamborghini was a sharp contrast from the central european or california based design studios but the result was outstanding

Bugatti Destrier looks like a swan song of Bugatti's VW-era. Unfortunately it's just a one-off, but like its Bolide sibling it shows the potential and range of the original W16 architecture. Tourbillion despite its V16 engine looks a bit derivative compared to the W16 range

I'm listening to my minidisc mixtapes I made 20+ years ago, such a great time capsule. Later I burned CDs mostly for listening on the car., but at some point I stopped doing it because the media changed so the timely compilation vanished, I should do this again on a monthly basis

A reminder that pilot errors are not for blame, as Burt Rutan said, after an accident "question [the cause] and never defend", these helicopters operate in very harsh conditions. A month ago another 214ST crashed during water scooping in a lake in northern Greece

Two Bell 214ST collided mid-air when the tube of one of them crashed into the main rotor of the other, probably due to proximity error by the pilot of the higher flying helicopter. They were operating during the wildfires near Athens and currently all 214STs are suspended.

#GoPro lifehack: if a battery suddenly dies and the camera doesn't open at all (or not even charging with this battery in) just leave it on the charger for a few hours, it's probably unbalanced and it will gradually come to life again.

The NASA Graphics Standards Manual* (1976) includes specific guidelines for aircraft liveries, explicitly stating that the NASA seal (let alone the meatball logo) should never be used alongside the new "worm" logo. Modernization is fine, but this is simply wrong.

Nothing keeps proving to the world that there's no better ROI than good design. They keep evolving their design language, making their products instantly recognizable without making them all look the same (quite the opposite) with minimal branding (despite a gazillion copycats).

Hot take: most of not all the high speed drones you see on the internets are far from being optimised, their design occasionally does not even make sense. Importing an .STL to a CFD suite and run a simulation does not make an optimised shape, just fancy renders

Brief review for Obsession: I saw it a couple of days ago, I expected a fun shallow movie but it was so much more than that. It's not perfect but it's accomplished, with great performances and direction, while it works far beyond the horror plot. I fully recomend it
