Gotta agree with you there, log splitters rule. We got a little 4 ton electric one for my mom, and on some pieces it would stall. I thought, what a wimpy thing, but then hitting those pieces it wouldn't split with an axe, I realized,

A 12 year old can indeed acquire that skill, but that doesn't mean any adult can do it.

I once took a sledgehammer to work so everyone could take a turn taking a whack at some old prototypes outside. I came to the sad realization that even hitting a particular spot with a sledgehammer is not an inate skill. If you've ne

Looks like its coded by someone who has never split firewood. The challenge is not deciding where to split, its executing the split. Like hitting the same gap if it doesn't split, deciding orientation to aoid knots, figuring out how t

A downside of profile shift is that you get away from the pitch diameter. At the pitch diameter, there's no friction on the teeth, the further away you get, the more friction. But any hand drill will have a gear with less than ten tee

The bottleneck with the pointer table may be the summation. While the fetches of elements can be parallelized, the summation can not, as the addition depends on the result of the previous addition being available. Some experiments I have do

An interesting aspect is data dependencies. If your next statement reuses data you just computed, that can cause pipeline bubbles, as that result you want to use just isn't available yet. I dived into that topic for a video about rel

nice, but spotted several inaccuracies on the landing page. perhaps not the best reference.

Disappointed to see the dots around it all appear to be the same spacing. They should be at different spacing, corresponding to strobe sync with 50 and 60 hz mains and 33.33 and 45 RPM. Hence four rings with different number of dots aroun

I'm sure they would not have been less than £850 in whatever currency it was sold in back then, inflation adjusted. But the justification was much better than being a fidget toy.

The JVM based devices came years later. This was around 1998, with the 386 based blackbery pager that could only do emails over Mobitex, no phone calls. It even looked like a pager. At the time, phones were not so dominant, data switched

I wrote the calculator for the original blackberry. Floating point won't do. I implemented decimal based floating point functions to avoid these rounding problems. This sounds harder than it was, basically, the "exponent"

Cutting away a lot with a router is a slow, noisy and dusty process. Less work to just glue together the channels out of smaller pieces of wood. Also, that way you can take individual pipes out and tweak them (called voicing). Another thi

I remember spell checking my essays for high school on the commodore 64, using Paperclip 64, in 1984, Before there was ANY Microsoft windows. Spell check took a few minutes, because it read the dictionary from disk as it checked, and afte

Actually not fair criticism, given that I even talk about changing the control parameters and demonstrate the effect of changing them.

Please re-watch the video, but THIS TIME PAY ATTENTION. I do talk about the motion parameters, even show the code on the screen briefly. I even show the effects of changing the parameters.

Things that scale can have a big multiplier, so to say. The problem is, more often than anticipated, that multiplier, rather than being large, ends up being considerably less than one. Whereas work that doesn't scale always has a mult

Since a daily activity once checked presumably never become unchecked, this could be just a big sheet of hexagons you can color in when the activity is done. Yes, you need to print out a new one once a year, but that's pretty trivial c

regardless of what happens inside the S-curve, the opening ends up getting a slight vacuum from suction, but there is no such suction on the opposite side. Imagine the S is straight, but a vane attached to the side of the pipe blocks suctio

chalk isn't a silicate. It's calcium carbonate. So no worries about silicosis. I think otherwise it would have been banned from schools long ago.

I have done something like that at times. I find the bug in the afternoon. Now I have the satisfaction of having found it and don't want to risk the frustration of it not actually being the actual bug I found. So I saved it for the

We use "science" to prove "they" are inferior.

I have come to that conclusion myself over the years too. But "bad people" or a holes also have usefulness. You sometimes need people to challenge things that only an unreasonable person would challenge. And you need the occasio

The first half of the movie mixes a lot of stuff up date and time wise, and adds a bunch of completely fictional sub-plots. I worked at RIM from 1993 to 2007

The time part is very important -- it's important to start 15 years ago when the field was less crowded, and then develop your skill as you go along.

Back around 2006 I used "panorama tools" to do the same sort of thing. It had this cool feature of being able to work out lens calibration if it had two photos from the same viewpoint but different angles. It did however require
