Finely balanced between upvotes for pointing out how bloated modern software is and downvotes from people who make their living writing modern software.
First place to look when this sort of thing happens is pprune.org - lots of pilots on there, often with specific knowledge of the aircraft type and/or of the incident itself.
For the DIYers, it's simple to get an SCD4x sensor and hook it to a pi, arduino, ESP32 etc (then use CC to create a live web interface). I did this after trying an Inkbird CO2 monitor, which gets reasonable scores in reviews and wanting a live web report in the office.
Interestingly the Inkbird and the SCD4X quite often diverge by anything up to hundreds of PPMs; I kind of back the SCD4x (on a Pi in my case) for accuracy after lots of experimentation, reading the datasheet and ensuring the correct calibration procedurs are followed (basically expose the sensors to outside air once a week).
It's also interesting how much it varies day to day in my one-person office - possibly down to how windy it is outside, even with windows closed one day it never goes about 800ppm, other days it'll hit 1500ppm by lunchtime if I don't open a window.
N.B. Quite possible the Inkbird uses an SCD4x internally, seems reasonable kit so I have no explanation for the differences in readings.
I get he's not popular. None the less it would be nice to see more nuanced comments.
In my experience IPO's often follow a short-period of upside (where those who already have shares gain some liquidity, i.e. actual cash) followed by a dip and then - depending on fundamentals - over time rise above the offer price. Mileage may vary.
Doing a long bike ride to visit a friend, the route I'd plotted suddenly found me in the middle of a big old runway, weird to see given it's alongside one of the major routes into London (one I've driven or motorbiked many times, but never cycled). Quite the shock to see, especially as it was a scramble to get through the bushes and cross the A3 to Wisley RHS.
Yes, when it makes the front page of the FT (2 days ago) you know there's some interesting stuff going on. The whole article is worth a read (I didn't known JD Vance's career was "largely bankrolled by Thiel").
>US tech billionaire and Maga donor Peter Thiel is starting a series of closed-door lectures about the antichrist in Rome on Sunday, putting him on a collision course with Pope Leo XIV, the Catholic Church’s first American pontiff....
As a strong supporter of Ukraine, I would say ultimately wars are won or lost by economic forces (the side that can't afford it any more loses). That's how the USSR lost the Cold War, and all I can hope is that all of Europe really has your back in this one.
Something based on the principles of 'New'? (not clear on the details of how Show HN works, does it automatically appear?). Just shove entries under 'New' and let the group decide what is "Show HN"-worthy.
Depends on the definition of slowly - thousands of photons per second upwards (and detectors are so sensitive these days that makes seeing easy). Lots of articles about on the subject, given the potential uses of this system.
The light is produced by electrons combining with holes, so the size of the material doesn't come into it (unlike an antenna). I've personally pushed* a single rubidium atom about in a quantum computer and watched it move by emitted light (rubidium atom: ~0.25nm, emitted light 420nm depending on excitation).
* Ok, actually pressed buttons that manipulated the electric field that was trapping the atom and watched the result on a display - lot of physics going on behind the scenes.
In the UK we have in fact discovered an alarming weakness in the concrete used to build schools, hospitals and other public building (in one case, the roof of a primary school collapsed without warning). The response was basically "Everybody out now".
It's pretty easy to do, a Pi (of any kind) and an IR LED that sends the power button codes for the common TV brands will do it (since it's often a toggle, it'll also turn TV's on if they are off).
RF remotes are harder to hack together but similar principle. Whether IR or RF, the codes are common across all devices of the same model/protocol.
In a similar vein, many years ago I helped someone with a similar problem with a neighbour who had the volume too loud. As the aerial cable was accessible, I suggested he stick a pin through the neighbour's cable whenever the volume got too loud, and pull it out when the volume went down.
Sure enough, after a while the neighbour learnt their TV only worked if they kept the volume down in the evening.
A spinning mirror is certainly an option, there are many projects around using them as projectors e.g. [0]. It would need precision faces and be a larger volume than the flapping mirror approach. Because the mirrors are spring-mounted and designed to resonate at ~50Hz they actually take very little power to drive - there's an optosensor on the back used to stabilise the oscillation amplitude, which is why the VB and Private Eye display widths vary during startup.
Can't see the video from this location, so may be just restarting stuff in it.
Unfortunately you can't get the LEDs any more - they were originally from LED printers and those all now use infrared LED arrays. I'm actually working on something similar, and am even using a few VB scanner mechs in development (driven by a raspberry Pi).
For further background, they were developed from an earlier system called the "Private Eye" - still a few references to them on the web e.g. [0]. I've built a circuit to drive one from a Pi Zero - amazing gadgets for 90's tech.
NP, and the exact definition of vibe-coding is, I think, yet to be determined. This wasn't a yolo, it was read all the prompts and generally accept them. Overall I'd say the code and web page are at least of a quality I've seen in many commercial settings; the code itself looks reasonable and if I was to do anything to it for a real 'release', I'd update the documentation which has suffered due to the extensive scope creep during implementation.
Also, I have a long tail.
