Major banks, media outlets and airlines are currently suffering major IT outages.
Flights have been grounded at Sydney airport, United Airlines has stopped flying, and the London Stock Exchange group’s platform is experiencing outages.
I'm curious about examples. I know many languages do not have word::word translations, but a concept that cannot be translated -- even if it needs a full sentence, is a very different thing.
There are words/concepts that require you to have lived in that culture for some amount of time to understand the cultural baggage connected to the word, and how the word actually describes a part of the culture. As a Swede, one such word for me is `lagom`, which is often translated as `just right`, but this is a cop-out that doesn't do it justice.
To understand it you must know, on a deeper level why a Swede values things being lagom, and this is surprisingly hard to put into words because it involves history, language, value systems, social patterns and even concepts like gratitude towards simple things. This word encapsulates a really big aspect of Swedish culture, making it impossible to translate accurately.
It's like how the Inuit have 35 words for "snow", or the Swedish have 51 words for "tax evasion". Some cultures have a need for nuances that necessarily gets reflected into the local language, nuances which will be lost when bluntly translating into the one category-level word in English.
The Inuit example is a common misconstrual [0]. The ancestor language has three root words that they might modify with a suffix in the way we might use a phrase 'snow on the ground'.
I wish, but most IT manuals everywhere are in English. But this is IT/CS, so using English at least to being able to read technical articles it's mandatory. Nothing too difficult, as my non-tech SO (native Spanish speaker) had read novels written in British English and to me that prosody and style it's hell compared to either an Stephen King or a Preston&Child one.
I've found zstd --long=31 to be an excellent replacement for lrzip. Mentioned it in the github issue as well, cross posting for context. I'm not associated with either zstd or lrzip, but would still be curious to hear if you find any remaining usecases in favor of lrzip.
At the 2020 Miami International Boat Show, Philadelphia-based Sharrow Marine introduced the culmination of a seven-year research and development project called the MX-1 Sharrow Propeller. Unlike every prop that's come before it, rather than blades, the MX-1 has loops of metal attached to the hub.
How does this change the dynamic? In a nutshell, much of a prop's inefficiency can be blamed on the blade tips, where vortices and cavitation (commonly called tip vortex cavitation, or TVC) form, creating turbulence and sapping efficiency. Simply put, the loops on a Sharrow have no tips. The net result is an efficiency gain of between 9% and 15%. But just as important, eliminating the cavitation vastly reduces vibrations and noise and makes for a smoother, quieter boat ride.
Company president Greg Sharrow tells us that the development of the MX-1 can be credited to music videos.
"I was trying to solve the problem of reducing unwanted noise from drones while filming live music productions," he says. "I've always thought it would be cool to use a drone to get cameras closer to subjects and film them from onstage, but you can't use drones for music broadcasts because they're too noisy. I knew that most of the noise comes from the blade tips and is caused, in part, by tip vortices. So, I'd have to find a way to eliminate them."
I think for water, what you really want is to _breed_ cavitation, but in a way where the jets created by bubble collapse are arranged to face opposite your desired direction of motion. Kind of like Astrophage.
Good question! Boat motors spin a lot faster than the "Underwater bicycle" propeller would so perhaps it's not as beneficial here, but would be interesting to try.
Utility scale wind turbines are already about 50% efficient which is close to the theoretical limit of 59% (Betz limit). The loopy blades would be more expensive to manufacture and transport so there's a trade-off and it's not obvious that efficiency would win.
