Java has a interface* called “Set” but the documentation is nebulous & ominous. “may throw an exception” what? does no one even know? There isn’t even a method for intersection & union?! What is the point? I taught my students to use the set object in Python. It was an elegant beautiful experience— Thought we could do it in Java but I think I will just use arraylist, write my own damn methods.

I’m biased, but Java is always more annoying like this. ugh. (*this explains part of my confusion)

@dr2chase@ohai.social avatar

@futurebird Isn't it (technically) an "interface", not a "class"? Not helping with the annoying, but the reason it feels underspecified is that it wants to allow very simple things to be sets, and so the requirements are as loose as possible.

5/2: Have you had an idea halfway or more through a project that required extensive rewriting of what you've already done?

This is NORMAL for novel-sized projects! I'm 85% of the way into a manuscript right now. The original plan was a Frederick Forsyth style tribute to "Day of the Jackal", but halfway through it was carjacked and taken for a joy ride by The Abominable Doctor Phibes.

Bonus extra: it's set in an AU 2015 and concerns the assassination of Queen Elizabeth II ...

@mjausson @Jennifer @ai6yr I read (elsewhere here) that there's apparently a surprising amount of virus in milk, and a human drinking raw milk is perhaps risking a lethal dose. So it may not be this deadly if transmitted cat-to-cat, but if they swallow a high dose in milk, it's deadly. (So drinking raw milk was already a risky venture, but with the risk of ingesting bird flu, just please don't, it could be deadly).

The reason why McKinsey/MBA types like Sundar and his recruits ruin companies is that ultimately too much focus and belief in shareholder capitalism thinks that companies are devices that produce money.

But neither do employees go to work with the wish to produce money for their shareholders, nor do customers buy products with that intent.

Employees want to help the customers and get paid for that. Customers want the value of the product. Money to shareholders is a byproduct.

@oblomov @HalvarFlake what motivates over-reliance on metrics is that at scale it is literally a management problem. Overconservative people (employees, managers, whatever) won't change fast enough to track (never mind lead) the market, but the excessively inventive will piss away resources jack-rabbiting after the latest pet rock. Numbers and dollars are very convincing to many people, thus their popularity as a management tool.

dr2chase,
@dr2chase@ohai.social avatar

@oblomov @HalvarFlake IMO numbers are a good choice if you have limited resources and many problems -- which moles do we whack first? An example where numbers are good is e.g. managing climate change, where one of the purposes of a carbon tax is to help a consumer decide between (for example) locally sourced lobster and air-freighted apples from New Zealand. But we don't have a manager for Elon Musk, who thinks the answer is Mars. /

dr2chase,
@dr2chase@ohai.social avatar

@oblomov @HalvarFlake Numbers fail when we fail to account for externalized costs, anything we can't measure, we either must guess a number or pretend it is zero, and factions will cook the guessed numbers to support their favorite choice. Conservatives will over-cost change. Imaginative jack-rabbits will over-cost failure to change, over-benefit adoption of their pet rock. And what has the security team ever done for us? And the privacy and user safety teams, they just slow down launches.

@futurebird @baldur that device, meh. But in datacenters etc, the special AI hardware (chips, even) provide a bunch of operations on lower-than-usual precision floating-point numbers. Used to be those were mostly 32 and 64 bits, sometimes 80, and maybe sometimes 128. The machine learning hardware works with floats that are only 16 or even 8 bits long: https://en.wikipedia.org/wiki/Tensor_Processing_Unit
That's new, not currently useful for non-ML stuff, and makes them faster and more efficient. /

dr2chase,
@dr2chase@ohai.social avatar

@futurebird @baldur it's not clear to me, but some of the models, to save storage space, are compressed into 4-bit coefficients, suggesting that perhaps 4 bit operations would be a good fit. And yes we can do 4x4 ops with table lookup, but custom silicon is even faster.

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, ???

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.

@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.
