Noted my car got time from GPS the other day and it got me thinking, why aren't there unencrypted packets on all wifi that distribute NTP time so my oven/microwave/alarm/etc can grab it from any wifi it can see (even if

There used to be a local hydro generation that fed the local city, they had 2 clocks on the wall, one on the local grid and one on the national one - some time late at night they'd speed up/slow down the local grid to keep the clo

Initially I think it was out of their own pockets, and they had a bunch of keen volunteers, who were also launching 'pong sats' high altitude balloons for highschool science experiments. While I was around the went from launching

Back when I was flying High Power Rockets at Blackrock these guys used to come out and use our FAA waiver to do their testing, they've been doing incremental testing for more than 25 years - that they did just go off and build their bi

Depends - as I learned when I moved to the US at least some of my mental maps are based on where the sun is in the sky (and the sun and moon are upside down there) took me a few months for it to all turn around in my head, there are still p

She may find herself in the position I was in after 20 years we left the US, I stopped using my green card for entering the US because I was no longer a resident, but didn't realise I was required to physically hand it in when I was do

Only in the US, just as the NZ$ is implied in NZ, AUD in Oz etc Certainly when the local media here reports on how much Donald Trump has to pay they convert from US$ to NZ$

Only 20x? I started my career programming on a mainframe system with a 1MHz memory cycle time (think of this as it's 'clock speed') - it had 3 megabytes of memory and supported 40 timeshare users (on terminals) and batch stre

You have to make your own, some people have SRAM compilers - depending on how big a tile you choose the more memory you get (it's going to be in the 100s to low 1000s of bits)

I taught a TT course at the local Makerspace last year, I'm pretty convinced that most capable programmers can be taught some simple verilog and can knock out a simple design pretty easily The hard part is learning to think about time

Tinytapeout 6 closes in a couple of weeks https://tinytapeout.com not too late to knock out your own chip. The basic idea is that you buy a chunk of a die, your design's pins get multiplexed to the outside, you pay a bit ex

I wonder if anyone has packet logs from the past few weeks that show attempts at sshd - might be some incriminating IP addresses to start hunting with

Yes it's a primitive form of gate array. The thing is gate arrays are sort of something between a full custom part and an FPGA, they cost less per chip than a gate array, but more per chip than full custom. On the other hand NRE (up fr

The bands are still around and still being used (though much smaller in trhe US than elsewhere) The main difference between DECT and the more free for all 2.4/5G bands is that in DECT the protocols are specified and designed to coexis

Looking at the video there was little traffic at just that minute ... but sadly it does look like there was a road crew up there

Also putting display core routines in ROM was important because RAM access was slower (because the display used 1/2 the RAM bandwidth)
293.
by Taniwha 3y ago
I think it started out in ROM, it has low core jump vectors so that portions can be replaced (rather than just the whole thing) I worked designing Mac graphics accelerators back in the day, we hooked them up by replacing bits of QD through

The real story here is that sometimes you start a project and don't really know exactly where you're going, as you get into it you start to understand both the problem and the answer you want much better - and then yes, you can ri

It's kind of worse than this - a virtual function call is a load (from the object) to get the vtable pointer followed by a load from an offset of that followed by a subroutine call from that pointer - it's kind of the worst thing

If you want to do this because you're pissed at the company and want to screw them over, don't ...... the best thing you can do is to leave, and leave them with this piece of software that no one understands and no one supports, e

it's a little more than that - as I mentioned above you can assign xs in a case statement (or anywhere you like) as a signal to you synthesis tool when you don't care what value something is - that allows the synthesis tool to mak

I use verilator all the time for open source stuff, but it has a real problem not supporting Xs - I use them to detect uninitialised variables and taken undefined case statements (with full_case) etc allows me to force faults at the same ti
