Where I live it is very common to do controlled burns in the spring time. The target is plains area that may include vegetation such as a forest area. You time it with the best conditions you can get: 1. Low wind day 2. Rain or humid days f

As far as spinning boards goes, you can get bare pcbs back from China in a couple weeks. If you pay extra, that can be 10 days. I use a Korean quickturn when I need the PCB shipped within 3 days, but it costs a pretty penny. Producing PCBs

It's always better to have as much functionality mutable via firmware update. Even if it's a day 1 factory update and it never gets updated again. You have an extra couple months to test and harden the design and prevent showstopp

All I can do is point someone in the right direction and give a few things to read. But nobody wants to read. Unfortunately, doing hardware is hard without reading. Lots of it. Choosing a part requires reading datasheets by the dozen or hun

Be forwarned, when I bought one, I had to email back and forth for a couple weeks with Xilinx and sign some legal stuff before they would ship it, even within the US. Might've been ITAR but they wanted to be really sure I wasn't g

This is the way. You explained it better than I could have. The example being an IO pin toggle is not great, because it's such a simple operation, and typically will be intrinsically atomic on many MCUs. Now, something like setting up

Embedded stuff roughly falls into 2 types: 1.Superloop, for simpler stuff. No worries about atomic register writes, at most you have a few interrupts. You don't need mutexes here. The overhead will always be low but it gets very hairy

Nand2tetris, skip around until you find something that interests you. Fpga4fun is a other good resource if it's still around. Try and do some stuff besides just another softcore CPU in the beginning, even if it seems redundant. Maybe t

CPLDs ran into scaling issues. Routing problems increase exponentially the more logic you add to them. Eventually routing delays make it pointless, not to mention power usage is horrific. Not many CPLDs were made beyond about 256 macrocells

You are absolutely correct, and because it doesn't scale well, you have to keep it highly targeted. It all depends on what you are designing. Something DSP focused like a MJPEG encoder can be entirely simulated as it can be abstracted

Can I make a suggestion - the DE0-Nano and DE0-CV. Lots of legacy IO while being an older device family that still has a very fast and efficient compilation time. Hardware wise, both have vanilla SDRAM, the CV board has 7segments, PS/2

Softcores on FPGAs tend to be used for housekeeping and babysitting silicon IP blocks. They never handle any actual data processing, because doing so in the fabric is orders of magnitude faster. The fastest softcore cpu at maybe 400mhz on a

I have various SGI machines and while they are cool, they are pretty much useless except for toying around on. And extremely noisy. The O2 is the only one that's usable like a normal PC, except the plastics tend to break during shippin

A popular one is indie games. An attacker will copy the entire game and distribute it on various platforms as if they were the publisher, and add a setup program - either a MSI or an all in 1 exe. This installer usually has a powershell sc

Is this a form of moral relativism where everyone and everything must have equal intrinsic value? What if we argue a 1971 Ford Pinto is actually just a good a car as a 2003 Honda Civic. Sure, it's old, the fuel tanks rupture in an acci

The hypothesis is that because of the very recent interest rate hikes and VC pullback, tech is now over, and the hot money will be in another field. Seems like a stretch, why would high tech salaries and another bubble not get created yet a

I use rar for backups as well. Its superpower is recovery records. Reading bytes off a hard disk doesn't always work the same years later. I have seen corruption on hdds. Also use it to span backups across multiple archival M-Disc blur

Agreed, people seem to only see blobs when they run on x86. A typical PC system probably has at least two dozen ancillary CPU cores spread out among the IO and peripherals alone. If I had a dollar for every 8051 that turned out to be inside

The first doctor I had wanted to send me to get my thyroid nuked because it was inflamed after a viral infection. After 2 years and 6 doctors I found I basically had long covid years before it was recognized. Probably from a low grade garde

This was my experience going through a half dozen doctors. I found a great one finally, but they didn't even bother taking insurance, and it was very expensive.

While I can't speak for an ideal subsistence farmer might act, out here in rural USA it would be very unusual for anyone growing crops to not store food and grow more than they strictly need. Canning, freezing and other forms of long t

That's true, which makes them perfect for Powerwall-type backup power, where weight is not a concern and the number of cycles will be very low. The other way to deal with low cycle count is to keep the cells only half-charged and minim

DRAM itself hasn't really changed too much for decades, and the length of time for the cas latency is determined by physics, so it's probably comparable to any other dram. Once you have the row open though, you can burst it out al

He's right, having been in the MAME source myself, it was designed as hardware documentation, not necessarily the most accurate emulator. Just look at the source for most any 3d polygon rendering platform. Take the gaelco stuff or the

It's very common for truck owners to not tow or haul 95% of the time. But when they do need to, the truck damn well better work. I asked a couple contractors what they thought about the Lightning, to them it's an expensive toy bu

I too am not seeing the gotcha here. The paper seems to be: 1. We ran a bunch of DDR4 outside spec directly with an FPGA, and the ram failed to nobody's surprise, and we characterized it. 2. We found a way to bamboozle the CPU's r

Sitting in the back seat of a Model 3 as a 6 foot person is a terrible experience. It is like this because of the rear of the car sloping downwards for aerodynamics. I avoid them whenever possible.
