There were a lot of things we couldn’t do in an SR-71, but we were the fastest guys on the block and loved reminding our fellow aviators of this fact. People often asked us if, because of this fact, it was fun to fly the jet. Fun would not be the first word I would use to describe flying this plane. Intense, maybe. Even cerebral. But there was one day in our Sled experience when we would have to say that it was pure fun to be the fastest guys out there, at least for a moment. It occurred when Walt and I were flying our final training sortie. We needed 100 hours in the jet to complete our training and attain Mission Ready status. Somewhere over Colorado we had passed the century mark. We had made the turn in Arizona and the jet was performing flawlessly. My gauges were wired in the front seat and we were starting to feel pretty good about ourselves, not only because we would soon be flying real missions but because we had gained a great deal of confidence in the plane in the past ten months. Ripping across the barren deserts 80,000 feet below us, I could already see the coast of California from the Arizona border. I was, finally, after many humbling months of simulators and study, ahead of the jet. I was beginning to feel a bit sorry for Walter in the back seat. There he was, with no really good view of the incredible sights before us, tasked with monitoring four different radios. This was good practice for him for when we began flying real missions, when a priority transmission from headquarters could be vital. It had been difficult, too, for me to relinquish control of the radios, as during my entire flying career I had controlled my own transmissions. But it was part of the division of duties in this plane and I had adjusted to it. I still insisted on talking on the radio while we were on the ground, however. Walt was so good at many things, but he couldn’t match my expertise at sounding smooth on the radios, a skill that had been honed sharply with years in fighter squadrons where the slightest radio miscue was grounds for beheading. He understood that and allowed me that luxury. Just to get a sense of what Walt had to contend with, I pulled the radio toggle switches and monitored the frequencies along with him. The predominant radio chatter was from Los Angeles Center, far below us, controlling daily traffic in their sector. While they had us on their scope (albeit briefly), we were in uncontrolled airspace and normally would not talk to them unless we needed to descend into their airspace. We listened as the shaky voice of a lone Cessna pilot asked Center for a readout of his ground speed. Center replied: November Charlie 175, I’m showing you at ninety knots on the ground. Now the thing to understand about Center controllers, was that whether they were talking to a rookie pilot in a Cessna, or to Air Force One, they always spoke in the exact same, calm, deep, professional, tone that made one feel important. I referred to it as the “ HoustonCentervoice.” I have always felt that after years of seeing documentaries on this country’s space program and listening to the calm and distinct voice of the Houstoncontrollers, that all other controllers since then wanted to sound like that… and that they basically did. And it didn’t matter what sector of the country we would be flying in, it always seemed like the same guy was talking. Over the years that tone of voice had become somewhat of a comforting sound to pilots everywhere. Conversely, over the years, pilots always wanted to ensure that, when transmitting, they sounded like Chuck Yeager, or at least like John Wayne. Better to die than sound bad on the radios. Just moments after the Cessna’s inquiry, a Twin Beech piped up on frequency, in a rather superior tone, asking for his groundspeed. Twin Beach, I have you at one hundred and twenty-five knots of ground speed. Boy, I thought, the Beechcraft really must think he is dazzling his Cessna brethren. Then out of the blue, a navy F-18 pilot out of NAS Lemoore came up on frequency. You knew right away it was a Navy jock because he sounded very cool on the radios. Center, Dusty 52 ground speed check...

Well shoot, now I need to make a COWABUNGA novelty keycap.

No need to go crazy with the first one. That first step from laptop keyboard or membrane pack-in is the biggest jump you'll ever make in typing experience. a brown-switch gamer board with the RBG turned off and some cheap Amazon "CSA" style keycaps might be all you'd ever need. Of course, even that type of thinking can lead to certain... rabbit holes.

I never truly learned to type, though I had a few weeks instruction in school, and did a few levels of Mario Teaches Typing when I was a kid. None of it really stuck, and typing remains an exercise in hand-eye coordination for me. I topped out at around 70-80 WPM if I'm composing rather than copying, but that's been good enough for a lifetime of office jobs, and certainly for writing school essays. There is definitely a lower ceiling if you don't get proper instruction, but simple practice is still helpful.

Drawing an imaginary factory- and they wanted kids to do this before teaching them the parts of the cell- isn’t going to help you learn what mitochondria are.

That sounds like it's an exercise meant to get the kids thinking about a multi-faceted system existing inside a single structure, with parts that are interconnected but distinct, and will lead into a common metaphor teachers use to teach about biological cells. Not being graded means they're not judging the kids on what they know or don't, but want to evaluate where they are with this sort of thinking and figure out what they will focus on. Also, your kid may be smart and already know where they're going with this, but others in the class may not. If she does, she could probably knock that out in fifteen minutes. Even if you decide that she doesn't need to do it, I don't think it's stupid busy work, at least not necessarily.

Some teachers are dumb; we need too many of them and pay them too little for each and every one to be a superstar. The ones coming up with curricula and lesson plans usually aren't, though.

Abiword is okay for now, I guess, but it's basically a zombie, waiting for dependencies to break:

I did once try to drop my largest book on my dad's head from as high up as I could get, my logic being that since it wasn't an anvil, which was clearly artistic license, he'd probably be fine.

This is also age and culturally contextual. If kid and dad are on the same page about why junior is still living there, and if Dad is financially secure, he may want kid to pay down debt and be ready to jump straight to a nice place of their own. Now, if the family unit overall could use the help, and there is no specific plan for junior to move out, and and they're just sandbagging to have more money in their pocket after paying down student loans, it could be kinda shitty. Paying down the debt is not bad; minimizing overall cost of living for the family is not bad; what Boop2133 does with their money beyond loan payments might be bad.

Pigeon sweat.

All those firmwares work fine, or even better, over USB. Of course, there's also the option to simply buy a kit. No idea if these people are legit, but the tech itself looks simple enough, a circuit board with contacts that let the linkage make a connection.

I am not quite sure I'd be ready to recommend it, but your more adventurous patrons may want to experiment. These keycaps are PBT, a cousin of polyester. They are not particularly pleasant smelling when heated or especially when burned, but they're not as unhealthy as ABS (the other common plastic for keycaps) and certainly not as bad as the straight up poison gas that comes from PVC. I use a basic 5W blue diode laser, coat the keycap with an "infusible ink" pen from Cricut (most of their infusible products are polyester-based), put it in an alignment jig, then laser a raster image "low and slow." My particular laser seems to do best when I do two or three passes at 2% power and 45mm/minute. The idea is to heat it roughly in line with the crafting heat presses without letting the heat spread and color in areas beyond the beam. I experimented with actually burning or engraving, and that sort of works, but (1) it's stinky, and (2) the ash wipes away and you're left with a mostly colorless letter-shaped indentation. The "dye sub" technique produces barely any fumes at all. There are a few people on youtube who've tried similar techniques, and quite a few who have used different heat or dye sources.

Aesthetically, the process was only marginally successful, though I'm optimistic about the longevity, at least compared to other low-end manufacturing techniques. I've been using a similar set of home-lasered keycaps for about a month with little to no wear. My jig was not as good on that set, AND I tried to center the keycap legends, meaning every fraction of a millimeter was painfully obvious. These legends didn't end up exactly where I might have liked either, but they're all off by the exact amount (about 1mm), so being consistent, the alignment isn't too bad.

It should be doable. The way these things are wired, you wouldn't use a common. You'd instead wire a matrix with diodes to avoid ghost presses. The firmware on the arduino or RPi microcontrollers will constantly scan for keypresses. So much would depend on the exact mechanism of your typewriter, but you could find a place where a keycap moves parts in close enough proximity to make your own switches, or if some part of the mechanism presses straight down, you could just have that actuate mechanical keyboard switches.

For wireless, you'd probably want ZMK. QMK is the most famous, but ZMK supports more wireless MCUs. I use KMK, a firmware where everything is human-readable python. I understand it has some wireless support, but I've never looked into it.

I thought a tombstone or a boogieboard. 🤣

More seriously, things get weird when you want to go no-stabilizers but don't want to buy a custom set of blank keycaps. This one only uses the 1.25u to 1.75u keys from a standard TKL or full size.

Doing it on the keyboard could very easily work, but I have a laser-cut jig that holds twenty-six 1u keycaps, and has one open-ended spot for anything up to maybe 3u. I considered 3D-printing the jig, but 30 minutes on the laser made more sense than 5 hours on the printer.

This plastic didn't love my "Infusible ink" pens, so the legends are duller than the last time I did this, but the jig helped a lot with alignment, as did adjusting my ambitions and expectations. Much less disappointing to land 1mm off when you can pretend you wanted it there all along, and that is much easier to do with corner legends versus centered. :-)

Thanks. Kind of a 2004 Apple and Logitech thing going. Probably need another couple of years before it's in vogue. white filament on the printer though, so white keyboard it is.

putting another tab button on the numpad

Horizontal spreadsheet data entry, my friend. it's probably one of the less crazy parts of this layout! Of course, ten minutes on the laser and/or 5 in the software, and I can make it any key you need. Programmable keyboards are a godsend when you're winging it on the layout.

I am currently typing on my one and only red-switch board, and I am mis-hitting keys like a mofo, and bottoming out even harder than normal. I don't type anywhere near correctly, but I make up for it by typing enthusiastically, and whatever the category, my favorites are always heavy.

From my keebtalk post, which also has more pics:

It’s early obviously, but I’m optimistic about this one. It feels pretty nice, and the Jades are almost as nice as the Navies, just missing that slight “kerchunk!” that the Navies have. The Jades are a bit snappier, and I agree that they may be ever so slightly louder, but I don’t think they dethrone my dark blue fingerbreakers.

After my last set of keycaps came out with some fairly obvious alignment issues, I rethought my jig and made a new one that could support 26 1u keys, plus one of arbitrary width. I also went with corner legends instead of centered, as that punishes a lack of accuracy much less, if you can at least get your setup repeatable. Then, I did clusters together in batches (i.e. all alphas in one run, all F keys together, etc.). The result is a much less jarring alignment situation. It would be ideal, if the plastic itself had cooperated. This PBT recipe didn’t like the infusible ink nearly as much as the DSA keycaps on my other no-stabs build. Legends are not as crisp as I’d like, and the colors are pretty muted, but the improved alignment makes this a modest victory.

Overall, I like (though not quite love) the way they came out, and the overall effect for the board, between the layout, case, and font, is a bit “Apple meets Logitech,” which may or may not be a good thing, but it’s always satisfying to wrap one of these up.

Would it be better or worse if the most popular large breed in the world were not erroneously referred to as a "Labrador" retriever?

Also, hello cousin. I've never been within a thousand kilometers of Newfoundland -- Boston or Montreal is as close as I got -- but I found out as as a grown-ass, gator-swimmin', boild-pnut-eatin' Florida-man that my biological grandmother was born and raised in Clarenville. Apparently, I have relatives from Moncton to St. John's to Toronto to Fort McMurry to Vancouver, and damn near every single one of them is mortified that that Granny's boy had a one night stand in the '70s. 🤣

At my rather beginner level, designing single parts for a 3D printer or laser engraver, it behaves almost exactly like most other parametric-history CAD apps in the broad concepts. The devil is just in the details, really. Shortcuts are different, terminology is different, Certain QoL and UI elements are either missing or somewhere else. The workbench model is not unique, but some of the kruft that has built up around FreeCAD's benches and the defaults (better in recent versions if you look at the start screen) can make a new user "nope out" if they have other options. I guess assemblies in particular remain a fragmented area and lag behind the commercial packages, and I can say for certain that it still requires "good design practices" in a way that some of the commercial apps manage around, toponaming the biggest among them.

If all the negatives kill your workflow to the point that you want to pay for commercial software or live with the limitations (current and potential) of their free tiers, then that's absolutely understandable. Commercially, it's doubly so, and with addition of the "business reality" that there's also no one to blame or sue if FreeCAD is not working for you. Hell, I don't use it for all my stuff either, as I find no-history modeling still mostly works for what I'm doing and I have some free or cheap options in that space that are decent, but I can see the appeal as I'm starting to make things that could benefit from tweaks after the fact. What I get frustrated by is claims that FreeCAD "is no good" or "will never be useful". I call BS. It's already good and useful for many use cases, and anyway the number of free parametric CAD suites that do not restrict your use of your designs is exactly ONE. Otherwise, you're looking at an absolute minimum of $300 a year to subscribe and hope that Shapr3D's new history functionality doesn't break, and that neither they nor Alibre gets gobbled up.

You're obviously trying to be thoughtful, and to a certain extent this is entirely subjective. If you, as any decent person would, think there are lines that you do not cross and that you treat service professionals with respect, then where is the line? You definitely don't throw shit on the floor intentionally, but you also don't offer to help cook, which you might at a family dinner. Every non-shitty person person will land somewhere in between, though hopefully a good ways away from throwing shit on the floor.

I think you're just running into a situation where your line is in a different place than other folks', to the point where you're a little out of step with the level of "help with the chores" that most people expect at a sit-down restaurant. If you continue to treat staff with respect, thank them for their help, and (if culturally appropriate/economically necessary) tip generously, then you don't have to feel bad. My wife waited tables and tended bar for many years, and it's not the specific tasks that are part of the job that ever made it feel degrading, it was people treating her shabbily and acting superior. No one expects you to clear the table when you're out; just don't act like you're too good to.
