The dark secret no one from the big providers wants to admit is that Claude is the only viable coding model. Everything else descends into a mess of verbose spaghetti full of hallucinations pretty quickly. Claude is head and shoulders above the rest and it isn't even remotely close, regardless of what any benchmark says.

As a GPT user, your comment triggered me wanting to search how superior is Claude... well, these users don't think it is: https://www.reddit.com/r/ClaudeAI/comments/1l5h2ds/i_paid_fo...

We don't have enough time to derive everything from first principles, but we do have the time to go over how something was derived, or how something works.

A common issue when trying this is trying to teach all layers at the same level of detail. But this really isn't necessary. You need to know the equation for Ohms law, but you can give very handwavy explanations for the underlying causes. For example: why do thicker wires have less resistance? Electricity is the movement of electrons, more cross section means more electrons can move, like having more lanes on a highway. Why does copper have less resistance than aluminum? Copper has an electron that isn't bound as tightly to the atom. How does electricity know which path has the least resistance? It doesn't, it starts flowing down all paths equally at a significant fraction of the speed of light, then quickly settles in a steady state described by Ohm's law. Reserve the equations and numbers for the layers that matter, but having a rough understanding of what's happening on the layer below makes it easier to understand the layer you care about, and makes it easier to know when that understanding will break down (because all of science and engineering are approximations with limited applicability)

Oh you put this nicely.

Something I heard but haven't dig into, because my use case (DIY, home) doesn't care. In some other applications approximation at this level may not work and more detailed understanding may be needed :)

And yeah, some theory and telling of things others discovered for sure needs to be done. That is just the entry point for digging. And understanding how something was derived is just a tool for me to more easily remember/use the knowledge.

Most of what I remember of my high school education in France was: here are the facts, and here is the reasoning that got us there.

The exams were typically essay-ish (even in science classes) where you either had to basically reiterate the reasoning for a fact you already knew, or use similar reasoning to establish/discover a new fact (presumably unknown to you because not taught in class).

Unfortunately, it didn't work for me and I still have about the same critical thinking skills as a bottle of Beaujolais Nouveau.

jve · 2 days ago

I don't know if I have critical thinking or not. But I often question - WHY is this better? IS there any better way? WHY it must be done such a way or WHY such rule exists?

For example in electricity you need at least that amount of cross section if doing X amount of amps over Y length. I want to dig down and understand why? Ohh, the smaller the cross section, the more it heats! Armed with this info I get many more "Ohhs": Ohh, that's why you must ensure the connections are not loose. Oohhh, that's why an old extension cord where you don't feel your plug solidly clicks in place is a fire hazard. Ohh, that's why I must ensure the connection is solid when joining cables and doesn't lessen cross section. Ohh, that's why it's a very bad idea to join bigger cables with a smaller one. Ohh, that's why it is a bad idea to solve "my fuse is blowing out" by inserting a bigger fuse but instead I must check whether the cabling can support higher amperage (or check whether device has to draw that much).

And yeah, this "intuition" is kind of a discovery phase and I can check whether my intuition/discovery is correct.

Basically getting down to primitives lets me understand things more intuitively without trying to remember various rules or formulas. But I noticed my brain is heavily wired in not remembering lots of things, but thinking logically.

How many cycles does the ebike battery go through in 200k+ miles? An EV car does ~300 miles/cycle. So 200k miles = 667 cycles.

jve · 3 days ago

Cycles is not the only variable in play here:

- Depth of Discharge - how often you go from full to low battery? Going twice from 80->30 (which accounts to a single cycle) is much better than single 100->0 cycle

- Thermal management - what are cell temperatures when battery is being charged? Maybe it is charged in direct sunlight? This will kill battery pretty fast. At what temperatures are the cells when driving the ebike?

- Ebike/scooter probably being charged to 100% more often than necessary.

- Did you leave your battery at winter completely discharged or fully charged in your garage? Bad.

TLDR: Info I gathered about reading how to take care of Lithium NMC batteries which are so widespread.

Throw-And-Exit is a custom function in the script @ https://github.com/brooks-code/WSL-VHDX-Compact/blob/main/ws...

jve · 5 days ago

Well in that case, a regular throw can be used. Don't see a need for custom function. From docs:

> The throw keyword causes a terminating error. You can use the throw keyword to stop the processing of a command, function, or script.

You’re not the only one. I invested months on Obsidian before walking away and returning to OneNote. It’s advertised as a ‘second brain’ but at its core it glorified overlay to the file system and a Markdown viewer. You can’t even manually sort notes and folders. Directory Opus can do that and more.

Moreover, the community plugins model is a fundamental security risk and the community plugins themselves frequently break on Obsidian updates. I’m not going to invest months to years building a curated personal knowledge base only to have it fall apart when a community plugins breaks.

For me it's a feature.

Actually great intro for step-by-step powershell scripting.

I thought I didn't know about "Throw-And-Exit" command, but no, my powershell doesn't have that and google also doesn't know a thing, so wonder what's up with that.

And instead of manual confirmations, one can write script with ShouldProcess support to have support for builtin -Confirm/-WhatIf/-Force parameters. And it would actually be a great use case for that scheduled task to run with -Force parameter instead of changing code to strip out confirmations. https://learn.microsoft.com/en-us/powershell/scripting/learn...

Of course everything is a product of its time, and in 1999 or any other world where the Internet is more of a cool new thing than serious business, it makes sense. But that was 26 years ago.

I am pretty sure the guys charging hundreds of dollars for IP addresses that cost them nothing to produce should be able to set up stripe, an identity verification product, and otherwise automate onboarding. Also, instead of writing giant process documents and slow-walking such wildly difficult problems as "allow domains to end in .cool" through infinitely nested committees they could try wielding their supreme governance over Who Owns Numbers And Names by killing off IPv4.

As long as ICANN/IANA remain in charge of Internet governance and operate with >$100mm budgets [0] "it made sense 25 years ago" is not a valid excuse IMO.

Fortunately the source code is available:

If I had the time, I'd try to compile a binary of it that will run on Win95 just to give my fuckings to the planned obsolescence crowd.

Like it is a one-off thing to support some system. You must maintain it and account it for all the features you bring in going forward.
