You will experience an apparent headwind when sailing on a broad reach faster than the wind, yes. But the jibe involves turning downwind (thus losing lift), as well as bringing the sails across (which will temporarily de-power them). It&#

I installed 4.6 kW of solar in 2017 for $20k. I got bids from 3 different companies and they ranged from $4.40/watt to $5.60/watt. All this talk of $1/watt is blowing my mind.

This is like the statement: “all models are wrong, but some are useful.” It is a true statement, but it doesn’t mean that all models are equally wrong, or that all journalism is equally biased. Objective journalism is an ideal to strive for

If a holistic reading of Damore's memo reinforced the idea that he was trying to deny the possibility of bias/discrimination, then perhaps you could call your inference a "reasonable implication." But the opposite is tr

by haberman 5y ago
He suggested that non-bias causes are possible contributing factors to the disparity, yes. Nowhere does he suggest they are the only causes, or that bias/discrimination do not exist.

Damore's quote says "in part" and "may explain," suggesting the possibility of multiple causes, and making clear that there is uncertainty. Your paraphrase says "the reason" and "rather than bias&#x2F

Thank you (genuinely) for writing all of this down, but nothing you have written is specific to PMod. I get that complex physical effects cause simple models of the world to break down -- that much is obvious. And of course it's up to

Yep, I'm undoubtedly missing a huge chunk of basic undergrad EE theory, seeing as I am a CS guy, not EE. That said, I think it's possible (even fun) to explain key concepts to people outside your own field in plain language. I p

What constrains PMod to low-frequency applications with sloppy SI? What inherently limits the frequency? I have been dabbling in FPGA programming on a Xilinx Nexys A7. Through some PMod ports, I've managed to drive the shift registers

TL;DR: I was wrong (but I did understand the distinction you are drawing) I'm aware that there is a difference between devious Monty and dumb Monty. The question I was trying to answer is whether this difference affects the actual out

by haberman 5y ago
I don't think this actually matters. Suppose Monty doesn't actually know which door has the prize, and just picks randomly between the two. Now the only difference is that Monty might accidentally pick a prize. Suppose he does.

by haberman 5y ago
When you choose the first door, you are partitioning the "board" into two parts: the door you chose, and "everything else". By opening a door, Monty lets you cover 100% of the "everything else" partition using

I wrote an article recently on a C-based fast interpreter technique that generates code comparable to hand-written assembly. I have an example where I specifically match some LuaJIT 2 assembly code in C: https://blog.reverberate

Yes, without the attribute the only option is to use macros to generate different code in debug mode, which is possible but far from ideal.

The tail call design gives more control over register allocation, and gets the compiler to generate better code by putting fast paths and slow paths in separate functions. I tried to explain this in the article and in my link upthread.

Barebone C looks really interesting! I wonder if the same gains could be achieved in a more architecture-independent way by simply introducing a new calling convention where parameters are passed in the registers that are normally callee-s

Bummer, thanks for the info.

I have to admit I had little interest in tail calls myself until I saw what they could achieve performance-wise. Now that I have seen that, I am sold. :)

Zero parse wire formats definitely have benefits, but they also have downsides such as significantly larger payloads, more constrained APIs, and typically more constraints on how the schema can evolve. They also have a wire size proportion
