I always love that @ternbicycles knows how to build bikes that speak to me, as. queer person.

The new Tern Orox: an all terrain cargo e-bike! In case I want to ride to the grocery store through the mountains! (Being very utterly serious about this!)

It's basically the Subaru for climate conscious lesbians like me

@ascentale @InkySchwartz usually, "bikes", sometimes not-e, sometimes acoustic. Bad ideas include "meat-bike" and "me-bike". I sort of like meat-bike, but somehow it hasn't caught on, can't imagine why not.

Technical sysadmin-ish question. We've had our family mail hosted at a bullshit rinky-dink server since forever, we pay too much, and today we had a mail glitch because some bullshit automated IP address filter triggered.

So, what's the process for transferring a domain name, plus all the IMAP mail on those servers? We have ssh access to a server, even. I researched this once, I think something like "Dovecot" is part of the answer. Not sure if I should look at bluehost, fastmail, ???

This is not "government", this is conservative dipshits. Also, the same assholes blocking aid to Ukraine.

    The least enjoyable part of coding is getting the IDE setup, the folders named, the correct libraries installed and trimmed down so they have what you think you will need.

    If the language is java then the least enjoyable part is deciding if you want to store a number as a float or an int (formatted if you need decimals) ... then always changing your mind and having to go through and fix the numbers so they work.

    I know python is lazy, but strict typing still feels like a drag to me.

    @c0dec0dec0de @futurebird @phryk IEEE has a mode for that, it's not random, pretty sure it is unbiased -- it's called "round-to-nearest, zero-if-tie". This is for binary, the idea is that if there is a tie, you choose the rounding that makes the least-significant bit in the rounded-to result be zero. So, 101.1 rounds up, to 110, 110.1 rounds down, to 110. Making the LSB be zero instead of one gets rid of just a tiny bit of future rounding (e.g., 110/2 = 11 exact, 101/2 = 10.1, needs rounding). /

    dr2chase,
    @dr2chase@ohai.social avatar

    @c0dec0dec0de @futurebird @phryk note that "division by two" was for sake of example, in real FP you would do that in the exponent unless you were in the denormalized range.

    This is the rounding mode that Java uses, and it is I think the default for most modern programming languages because overall it gives the best results for binary floating point.

    @futurebird One thing that's pretty clear is that LLMs don't learn very efficiently. None of us inhaled that much data to learn to speak one (or more) languages. None of us inhaled that much data to learn to recognize dog breeds, or plants, or ants, etc. The thing that the LLMs seem to have learned better than (most of) us is multi-subject "man on the Internet" confidence.

    OTOH, perhaps our human ability to "learn efficiently" makes us vulnerable to learning conspiracy theories from bullshit.

    @seachanger @CathyTuttle Taking a lane definitely generates some abuse for men, but no surprise if there is more for women. I pick routes to avoid conflict nowadays, helps that roads are better now (in Boston area). Would be interesting to see how that study would go around here.

    Here’s a dumbass bike route I just rode, which I’m convinced is the optimal east-west route in South #Berkeley.

    What makes it optimal?

    • every arterial crossing but one has a traffic signal
    • it’s mostly on side streets

    What makes it dumbass?

    • it almost completely avoids Berkeley’s “Bicycle Boulevard” network, meant to be the best bike routes around town
    • none of the signals have bike detection
    • it involves five, one-block jogs north-south
    • no novice rider would ever find it without help

    @marcprecipice contrast with recent visit to Amsterdam, first time ever (with the caveat that I am stupid-comfortable on a bike). I just pointed the bike, and went. It just didn't matter, all the routes were pretty good to great.

    @marcprecipice I have done a little bit of riding in Copenhagen, Amsterdam seemed even more like that, to me.

    @marcprecipice but I also cannot help but think that the US is full of people who have accidentally/enthusiastically deprived themselves of the ability to bike comfortably in a place like that. There was definitely a lot going on in Amsterdam.

    @afilina the fine-grained weather simulations say you want to be east of a line connecting Montreal to Montpelier, VT (roughly). It will be very near for us, almost certainly cloudy by 1630 (one hour after).

    You have a spare M1 Probook to upgrade him to. What could possibly go wrong?

    Well, he's forgotten his login password, never had an AppleID, and his old machine doesn't recognize APFS filesystems for that old-time floppy-style SSD shuffle.

    And the cable to the only SSD they have is flaky.

    dangit, my inner data structure has a structural fault because of rust ownership semantics.

    Conceptually, the inner struct is a binary tree where inner nodes can carry a value, and leaves can carry a value or a child tree. If you need a leaf to hold both a child and a value, you store the child and move the value to the child's root node.

    Conceptually again, lookups walk down this tree-of-trees looking for the node representing the lookup key, and nearest self-or-parent value is the result.

    dr2chase,
    @dr2chase@ohai.social avatar

    @danderson if, extremely hypothetically, Go gave you the option to say that a struct was "bit packed", and by that I mean that you could (say) stuff a pointer-to-4-aligned and two booleans into the space of a single pointer, but you could never, ever, take the address of any of its fields, and they would all race together -- is that worthwhile? Less than zero promises, I'm just curious whether that would work well for you or not. There's lots of reasons this will never happen, of course.

    dr2chase,
    @dr2chase@ohai.social avatar

    @danderson That's actually a type system problem, not a GC problem. The GC is amusingly omnivorous in its consumption of pointers. This would require implementation of tagged unions, which in a "hack" form would embed the tag in the unused pointer bits (assuming that any are unused) and otherwise in an extra field. HOWEVER, access to the pointer + field would require double-wide aligned stores to avoid creating new tearing stores (we want to get rid of the ones we have, not make new ones).

    @danderson The Go GC recognizes interior pointers, yes. I'm surprised nobody else has done this, it's horrible, but I've seen much much worse.

    @CelloMomOnCars I look at it from the POV of someone who grew up in Florida in the 60s and 70s -- a zillion people moved to Florida then, the county I lived in and the two land-adjacent counties grew 3% per year (compounding) for at least 20 consecutive years. People moved in for decades, I expect people will move out for decades. But/also, Florida is not all low, the next century's sea level rise will mostly affect the most-coastal areas. /

    dr2chase,
    @dr2chase@ohai.social avatar

    @CelloMomOnCars the county I grew up in (Pinellas) has a lot of high ground, and a lot of low ground, and I'm curious what the high ground reaction will be to the low ground getting increasingly wet. In most of our lifetimes, the rate is likely to be slow (but steady), not more than a foot per decade (3 meters per year, well faster than most current this-century estimates). Someone 25 feet up, they could put off worrying for 100 years.

    dr2chase,
    @dr2chase@ohai.social avatar

    @CelloMomOnCars but some of the infrastructure is at risk -- roads with low sections will be cut, salt water intrusion will mess up water supplies, cities with high and low-ground areas will be under financial pressure (barrier island municipalities will fail). There will be this weird tension on high-ground property values between displaced locals wanting to stay on the now-scarcer land, newcomers staying away, and high-ground locals deciding to get while the getting is good.
