I'm starting to use AI increasingly, and am getting some value out of it. I'm curious if paying for paid tiers of the big players (in particular, ChatGPT and Claude) provides significantly better responses.

I'm aware that the paid tiers offer more features and benefits than just higher response quality. For me, those are just nice-to-haves, and not my primary concern.

My main uses of AI are software development and foreign language learning. So far, I've used the free versions of ChatGPT and Claude, as well as "proxies," including Github Copilot and Duck.ai. For both my use cases, I've found the responses usually good and helpful. I just maintain a healthy skepticism about the correctness of the answers, and challenge, test, and double check where needed (especially testing suggested code when developing software).

Have you found response quality to be noticeably and significantly better with paid tiers? I was just randomly thinking, and it occurred to me that the cost of an AI subscription is in the same ballpark as a subscription to a language learning service like Duolingo. So, if I can get value from AI that approaches what I'd get from a dedicated language learning service (even if it doesn't quite match or exceed it), then also getting the value of general AI in the same subscription should make things quite valuable and worth it. Not to mention possibly getting better software development assistance in the same package.

They aren't a startup anymore, but it seems the current CEO, Tony Stubblebine, got it right, according to his latest (long) blogpost.

Although Medium is in a healthy path now, they burnt goodwill so many times in the past that my trust on the business is absent. I wonder how other people perceive them…

Any clever ways to connect to the Internet safely to update drivers, security, etc? I'd only want to connect to Intel, AMD, Microsoft, etc, and then would physically disconnect the lan card. I know, dangerous, but I'm trying a piecemeal approach with a flash drive and getting mixed results. I tried to update to Service Pack 2, and it bricked the computer on restart, back to flashing Vista.

Sorry if this isn't the best place to ask. IT and cybersecurity-focused communities over on Reddit aren't exactly the most welcoming places for such questions, and reading the r/ITCareerQuestions wiki has made me seriously question if I'm being sold false promises of working in a sector that actually has a low demand for workers. Then again, that wiki page seems more geared towards the US job market.

Two weeks ago, I responded to an Instagram ad advertising cybersecurity courses, because the job market is horrible here in the UK right now, and after some setbacks with my ACCA studies, I am seriously considering just giving up on trying to get into chartered accountancy because that path is closing many more doors for me. A course advisor rang me asking about the reasons I showed interest in the ad, then we had a long discussion about any questions I had, what the sector is apparently like, etc.

Some of the claims seem too good to be true, i.e. that it's an industry where you can afford to be picky, jobs outnumber people by almost 3 to 1, most jobs are remote, the provider boasts a 90%+ employment rate, I don't need programming experience, the most complex thing I'd be doing is running command prompt/powershell commands and scripts.

The firm itself seems legitimate. They offer CompTIA, Microsoft, Cisco, AWS and EC-Council certifications, have good review scores on Trustpilot, are a registered training provider and limited company in the UK, and are supposedly an assured service provider with the National Cyber Security Centre (NCSC.) The courses they mentioned to me in their syllabus supposedly come to £4k and would take about six months.

1. Am I right to be wary about what this training provider are offering?
2. Do you require extensive programming knowledge or a computer science background to work in cybersecurity in any capacity? A friend with an IT background has told me that Python is useful in his field.
3. Is the reality of IT and cybersecurity jobs in the UK (or in the West) far different from what has been painted to me?

Piano keys are familiar and easy enough to draw if you're not trying to be exact, but if you want label the dimensions with their exact measurements (like in a CAD drawing), it turns into a math puzzle. The problem comes from the groups of two and three black keys.

This article explains it like this:

If you've ever looked closely at a piano keyboard you may have
noticed that the widths of the white keys are not all the same
at the back ends (where they pass between the black keys). Of
course, if you think about it for a minute, it's clear they
couldn't possibly all be the same width, assuming the black keys
are all identical (with non-zero width) and the white keys all
have equal widths at the front ends, because the only simultaneous
solution of 3W=3w+2b and 4W=4w+3b is with b=0.

To unpack that a bit: in that equation, 'W' is the width of each white key at the front (which should all be the same), 'w' is the width of a white key at the back, and 'b' is the width of a black key.) The first equation is for the group of two black keys (separating C, D, and E) and the second equation is for the three black keys separating F through B.

Since it's mathematically impossible, a constraint needs to be relaxed. The article describes ways to make the white keys have slightly different widths at the back.

If we set c=e=(W-5B/8) and a=b=d=f=g=(W-3B/4) we have a maximum
discrepancy of only B/8, and quite a few actual pianos use this
pattern as well. However, the absolute optimum arrangement is to
set c=d=e=(W-2B/3) and f=g=a=b=(W-3B/4), which gives a maximum
discrepancy of just B/12. This pattern is used on many keyboards,
e.g. the Roland PC-100.

When actually building a musical instrument (instead of just drawing the keyboard), there is a further constraint, described in this article:

The black keys on a piano keyboard, instead of always being centered on the dividing line between the two white keys they lie between, are spaced so that the twelve keys which make up an octave are spaced equally as they enter the internal mechanism of the instrument.

But this means that the "key caps" for the white keys should be slightly off-center compared to whatever rod or lever they're attached to. The author speculates about how to divide this up using various units.

(They seem quite annoying to 3D print.)

I'm in the planning stages of a custom setting for a new campaign I'm aiming to start next year with my current table. We're doing PF2's Kingmaker and AD&D's Temple of Elemental Evil in the meantime.

The game is to be Viking themed, in that the starting locale and civilization will be structured in similar ways to the coastal Scandinavian settlements and there will be an on/off season. During the on season, they will board boats and sail many hundreds of miles across water to distant lands to find dungeons and ruins to loot, with a clock they have to keep an eye on; the expedition can only afford to be out for so long, and they need to ultimately make a profit. During the off season, they will be home and can spend time locally engaging in low-tier politics, explore the untamed parts of the continent, or both.

I'm intending for gods to play a more concrete and available part in this game and have been chewing on how best to represent that mechanically. I discovered that one of D&D 5e's supplements for a Magic: The Gathering setting, Mythic Odysseys of Theros, does something similar and has mechanics for tracking Piety with a given deity, which comes with boons at specific breakpoints. I liked the idea, though I'd be making my own boons for my pantheon rather than use these as-is, especially since I wouldn't be running this game in 5e, but rather in AD&D 1e.

I have a group chat with a few of my players that I can trust for this kind of thing to bounce ideas off of for various things, so I put this forth to them and got their thoughts. They universally thought the example boons from 5e were too personal and individual for the kind of stuff Norse gods would get up to, and there wasn't really a way to track a given deity's disdain of you in a similar manner. They also didn't like that you could track the Piety with a discrete score and could reliably measure when your next boon would be.

What we settled on doing is utilizing my custom tarot effects we're already doing in my regular AD&D campaign, but having it apply in certain regions or during certain stretches of adventure. This would allow for randomly coming across an avatar of a god and earning a minor boon or bane for assisting or denying them.
