It's significantly more expensive, usually around 30-100% more, depending on capacity. IMO not worth it on a desktop, possibly worth it on a home server or a serious workstation. Plus your CPU and motherboard has to support it, which i

It can be, quite effectively. Nuclear waste is more or less a solved issue from a technical standpoint, with the caveat that there are a lot of gotchas but the general concept is well understood and several other countries do it to some deg

Yep, I use both on my FreeBSD server. RAIDZ is great, though like most non-enterprise users I wish ZFS was a bit more flexible when it came to growing volumes. I also use `zfs send`, that's what I was referring to with moving jails aro

Yeah, kind of my intent. IMO, the real job of an engineer is selecting compromises to stay within a budget, be it a financial budget, safety etc. If hypothetically you have a legitimate reason to write a Javascript OS kernel then go for it.

What are your thoughts on languages like Haskell? It certainly isn't simple or easy by any means, but it also isn't anything like nuts-and-bolts systems languages like C or C++. It gives you a lot of strong guarantees of correctne

Pointer use is rare in Fortran, too. I only really see it used to create views into arrays. But Fortran has a ton of features that aren't used much, e.g. the OOP stuff (which I've never seen used seriously and I'm moderately

So the author has a great point, that languages are suited to different things. I like this. What I don't like is the implied "only people doing stuff that I think is hard are real programmers." The author seems to believ

Err most common meters are not rated for 1000V and especially not mains current levels, not even a lot of nicer ones. Are you maybe thinking the probes? Those usually have much higher ratings than the meter. Browsing Amazon... * Fluke 113 -

There's a huge difference in terms of input protection, actually. Fusing and a bunch of other protection circuits are the first line of protection... most cheap meters will have a glass fuse and little else (some not even that https:&

Yeah, you have to pay for the extra liability the company incurs by rating things for extreme usage. I draw an analogy with multimeters. I've got a cheapo multimeter with a safety rating that (dubiously) claims it's perfectly fine

Eh not really, it's just a resistive heating element + impeller + temperature sensor + microcontroller. And implementing PID and tuning the parameters is not that hard as it's such a common and well-known algorithm. I built a sous

The major advantage PandwaRF has over an RTLSDR is that it also can transmit. The RTLSDR's only receive.

It's an SDR, so it can transmit and receive over multiple frequencies. It's basically a programmable transceiver that can be used to interact with many different protocols and transmission encodings on different frequencies. Looks

Lots of routers support this, even single-radio consumer stuff with DD-WRT but it dedicates half your bandwidth to uplink and half to clients. Others you can use e.g. the 5ghz radio for uplink and 2.4ghz for clients. I presume there is some

Not OP, but the ATTiny is pretty easy to work with because it doesn't need much in the way of external parts. You need an AVR programmer, but you can use an Arduino flashed with the AVR programmer sketch or buy a cheap tinyISP for ~$10

Same, I had a lot of trouble with the DHT22 calibration, for temperature as well. And it was nonlinear, so I couldn't just add a correction. I switched to a mix of BME280, Si7021 and DS18B20s. Si7021 is pretty similar to the DHT22 in t

No, because you also need to increase the pressure of the water for it to cut. The nozzle increases the pressure of the water by constricting a constant flow into a smaller area, which increases the kinetic energy of the water and the abras

I don't think this would work because the particles are free to move within the water stream. Say you used something like a magnetic pinch ( https://en.wikipedia.org/wiki/Pinch_(plasma_physics) ) to focus the stre

You have to be careful with isolation transformers because there is one gotcha... the ground pin normally passes through to earth. I've witnessed someone blow up a nice $5000 Agilent oscilloscope before I could stop them because they d
