A gun, like a Glock. It’s on video. No arrests made. To be clear, this gun incident is unrelated to the stabbing you support
would you happen to have this video? and please don't say I support stabbings you dumb motherfucker.
looks like some kids shooting an airgun? in their backyard? not entirely surprising that the police didn't break down the door on suspicion that he might stab someone years later.

Vickram Digwa's neighbours reported him to Police for firing an illegal gun in his back garden. The police said they could do nothing despite video evidence because no other residents had made a report
he had a gun? like, a Glock? what are we talking here
surely the most wasted branding in the world is all the names of production companies that they show you before the movie starts
there it is

This was the one you meant, right?
So Hampshire police had written out a statement saying the attack was racially aggravated, as in, Nowak was the aggressor because he was racist. His father had to beg them not to, which is good because the trial determined that wasn’t the case anyway.
Weird, I thought you said the police did everything right in this case and this didn’t reveal any biases in their policing
that's because you can't read; I said it was sloppy police work and the police have an obvious bias towards whatever narrative was established by the callout, that's why people SWAT each other.

traditionally a "ceasefire" means you cease firing, but technically they didn't call for a ceasestrike so it's fine
You’re on a date with an attractive girl. She’s wearing a tight dress and clearly put effort in.
Instead of: “You look amazing!” (which makes her feel secure)

hopefully blended wing body aircraft take off (so to speak) and make all movies featuring tube and wing aircraft look obsolete, although it's taken over a century to get this relatively modest shift in form factor; a good test for beliefs about the AI singularity is to imagine what it might do to air travel.
Call me a pessimist, but if the robots don’t take over I have this nagging feeling that blended wing bodies and open turbofans are going to become commercial aviation’s “eternally 10 years away” tech.
Of the two I have more faith in open fans becoming a reality even though the technical challenges are (aiui) harder, just because the potential efficiency gains are so significant. In contrast, although there’s no single dealbreaking engineering obstruction to blended wings, it’s going to require a complete ground-up rework of basically every aspect of how planes are designed, constructed, and handled on the ground for a comparatively modest reward. I feel like people are underestimating the costs involved there.
I don't really understand why these propellers look so funky and marine like but the technical challenges do seem significant.
The blades are moving faster near the tip so the apparent direction of the air (which is the sum of the plane’s linear velocity and the blade’s tangential velocity) changes, meaning the blade actually has to twist to maintain a constant angle of attack. The same thing is true for normal turbofans, the blades are just smaller and enclosed so it’s harder to see.
so do they look different to a regular propeller, like on a Cessna or something, because they have to spin faster?
Pretty much. Conceptually, a propfan is just a turboprop designed to operate in the same performance envelope as a traditional turbofan (30,000 ft, >0.8 Mach). Even regular propellers have a bit of this twist too, but since they spin much slower it’s way less pronounced. One of the big qualitative differences is that traditional props are subsonic whereas to reach the aforementioned performance figures propfans have to be designed for the majority of the blade to be supersonic, and aiui that’s responsible for most of the obvious differences between the designs (more, thinner, bendier blades). Regular turbofans partially get around this by using the cowling inlet to slow the incoming air, so the majority of the blade sees a subsonic airstream. The tips are still supersonic, but being right up against the cowling helps suppress a lot of the noise and inefficiency that would otherwise produce. The fact that propfans are exposed to the full unmitigated airstream and have nothing to help suppress the tip shocks is most of what makes them challenging, I believe.
I see, lots of tiny little sonic booms, sounds like the cavitation difficulties that afflict fast water props.
I gotta say, without the cowling these engines do look a little ungainly, they lack the elegance of the classic turbofan, even the huge ones.
Ok am I the one who has to be juvenile and note the positioning of the two planes in the preview image and the phrase "it's really coming"
that's why propfan planes look so strange, they're weird crossbreed hybrids, the mongrels of the sky

If you want a movie recommendation, try Mad God, plus the story about the making of the movie is interesting in itself
looks like something Terry Gilliam might make!
bit grim though isn't it, might rather watch John Oliver

Want any movie recommendations?
You should watch Masked and Anonymous (2003), it’s a Bob Dylan movie with an ensemble cast. The plot: a tv network tries putting on a benefit concert in a dystopian future American dictatorship
didn't know that one, looks interesting! watching Vanilla Sky, would recommend A Serious Man among others.
hmm Masked and Anonymous is not available for streaming in Australia, which is a pity as the reviews are incredible:
On review aggregator website Rotten Tomatoes, the film holds an approval rating of 26%, based on 82 reviews, and an average rating of 4.03/10. The website's critical consensus reads, "Unintelligible and self-indulgent Bob Dylan vehicle".
Chicago Sun-Times critic Roger Ebert gave the film a 1/2 star (out of a possible four) rating, and deemed it "a vanity production beyond all reason". A number of reviewers commented on Dylan's acting, writing that he appeared "near-catatonic" and that he stared "in mute incomprehension", "never speaking more than one line at a time" and only making remarks that "evoke the language and philosophy of Chinese fortune cookies". The film was also panned by Rolling Stone, Entertainment Weekly, The Village Voice and at least twenty other noteworthy periodicals.
such a star cast with such a poor reception practically demands viewing
The toxic legacy of wartime dumping could take centuries to clean up.
In the middle of these weapons graveyards in the North and Baltic seas live rich, diverse marine wildlife—but the scale of pollutants permeating the water is putting those organisms in harm’s way. One animal in particular provides the best evidence of this: flatfish. Scientists have uncovered alarming traces of TNT and its metabolites in the muscle tissues of fish living near North Sea unexploded ordnance (UXO), with recorded concentrations of up to 4 nanograms per gram (ng/g).
I put TNT in the wine... and the flatfish
