Your link shows the Dartford Crossing, an M25 bridge miles downstream of the City. The Blackwall Tunnel runs under the Thames at Greenwich and afaik just has the old school hanging metal blocks at height https://maps.app.goo.gl/N5xSF148ggLVTDtS8

It doesn't surprise me too much that police are on standby, a closure of either tunnel or bridge has a major effect on traffic all over London

peteri · 10 months ago

There are additional traffic lights on the blackwall tunnel further in and a slip road out that can be used for overheight vehicles. I do remember having a 10-15 minute wait once while they sorted things out when a lorry driver got caught.

I'd have a feeling there are automated signs prior to the tunnel (or at least used to be) but I've not been through the tunnel for a year or so and things will have changed with the Silvertown tunnel opening.

I have seen someone not paying attention at the Rotherhithe tunnel and the roof of their van was a mess (and they're going to pick up a fine probably due to restrictions, the 2 tonnes gross weight limit is lower than a lot of van drivers expect)

Edit there were: https://maps.app.goo.gl/MP7fkhS394DJPQaZ9 If you zoom in you can see the overheight vehicle warning.

The ship is wood and his system required large amounts of copper, including sheeting covering what I understand to be a fairly large part of the hull. I imagine the fitting process was also not inexpensive given that.

peteri · a year ago

Copper was already on the bottom of the ships by then to stop ship worm (terodo Navalis), it also had the advantage of stopping weed growth.

A quick browse through Wikipedia suggests that entire Royal Navy had copper by the late 1790s.

And no laws or legislation have been passed or proposed to close down said institution, is that accurate?

peteri · a year ago

As far as I'm aware they do need an act of parliment to close it down. The one to create the market on the current site is an Act of Parliament (The Metropolitan Meat and Poultry Market Act of 1860) which should protect the site from becoming anything but a place to provide Meat & Poultry

For the UK the Scottish national library has a similar map finder.

Those are Vega, not CDNA. It wouldn't surprise me if those are rebranded consumer chips, though I haven't checked.

peteri · a year ago

Wendell over at level one techs seems to think that AMD cards are more popular in pro applications.

Steve Wozniak did DOS 3.3 for the Apple // and the SOS for the Apple ///. He open-sourced a lot of his work for others to learn from.

peteri · a year ago

DOS 3.3 was mostly Shepardson Microsystems Paul Laughton and Randy Wigginton from Apple. Woz supplied the RWTS routines for reading / writing sectors.

I’ve always wondered how the apple 2 pal version worked due to the way the us version used ntsc artifacting from my understanding for some aspects of the graphics.

peteri · a year ago

There is a detailed description of the circuit with the PAL colour card (it's on the euro //e motherboard) in Understanding the Apple //e by Sather (see archive.org for a copy) on pages 8-16 -> 8-19.

You do get the green/purple fringes on text, the euro //e has a switch on the motherboard that turns off the TCA650 and forces mono mode which is handy for 80 column work.

I _suspect_ you don't get all of the NTSC artifacts since PAL will be a bit better, but I really need to get my TV plugged in on my //e running one of the games (adventures typically) that use artifiacts to check.

The other alternative is the apple authorised ITT2020 which added an extra bit to the display so shows "jail bars" on screen when running ][ software. Again I should drag mine out to do some testing.

taspeotis · 2 years ago

My rough understanding is that this is similar to async/await in .NET?

It’s a shame this article paints a neutral (or even negative) experience with virtual threads.

We rewrote a boring CRUD app that spent 99% of its time waiting the database to respond to be async/await from top-to-bottom. CPU and memory usage went way down on the web server because so many requests could be handled by far fewer threads.

peteri · 2 years ago

It's a different model. Microsoft did work on green threads a while ago and decided against continuing.
