プリアンプは管球式を自作するのが一番

（前略）一般に、メインアンプは輸入品で、かなり割高になっているものは別として、価格がその材料構成からみて、割合うなづけるものですが、プリアンプは加工賃及び技術料が大きな割合を占めておりますので、製品の値段がどうしても高くなります。しかも良い製品となると、その材料費の4〜5倍、あるいは、それ以上の価格がつけられるのも当然のことと思います。

となると、プリアンプは管球式を自作するのが、一番という結論に達します。メインアンプのように、材料代が大きく性能にひびいいているのと違って、プリアンプの良いものを原価で入手する方法はこれが一番です。

ところが、作ることが楽しい式のプリアンプなら、あまり問題はないのですが、最高級の実用機を製作するとなると、そう簡単にはゆきません。そんなに簡単にできるものなら、￥240,000もするマッキントッシュC22が売れるはずがありません。

When Good Friends Give Bad Advice

1 “Call now; is there anyone who will answer you?     To which of the holy ones will you turn? 2 Surely vexation kills the fool,     and jealousy slays the simple. 3 I have seen the fool taking root,     but suddenly I cursed his dwelling. 4 His children are far from safety;     they are crushed in the gate,     and there is no one to deliver them. 5 The hungry eat his harvest,     and he takes…

I did a bit of de novo genome assembly way, way back in the day which I have never been able to use professionally because my PI refused to spend $2000 more on getting new read depth. He had ordered the reads before actually learning anything about the pipeline and only about half of the libraries he had ordered were usable in any given pipeline, see. (Some had been for older assembly methods and others had been for newer ones, basically.)

Rather than find the money to fucking get me the reads to do it right, he heard about an open source project called RACA that was some dude's dissertation arguing that you COULD use some of the worthless libraries to fill in the gaps of the assembly and get a functional genome out of it. I spent two years trying to move massive quantities of data through that fuckhead's pipeline on the campus supercomputer to get the assembled genome out, and then I got to the end and found there was no output as fastq files or ant other format recognizable to me.

(Give me a break, I was 23 and had also been frantically learning acoustic analysis, basic electrical engineering, and technical equipment maintenance in the two years since I had started learning to code. Plus I was figuring out what I wanted my dissertation to be. I'd never grappled with anything more complicated than our home-written library of matlab acoustic analysis before, and it simply hadn't occurred to me that anyone would publish a non-functional pipeline to achieve a goal quickly anyone verifying that anyone else had done anything yet.)

Anyway, eventually he collaborated with someone else who ponied up $2000 and a postdoc to get new reads. My name was not on the paper, so that's two years of my life developing a particular and fairly unique skill set that I will almost certainly never use.

In retrospect it's less surprising than you might think that the PhD took eight years and absolutely shattered my confidence.

And the best part is that it was just about impossible to predict at the time that shit would go quite this bad, except that some people handle power well when they're stressed and some people maintain a strong layer of cognitive dissonance over their knowledge of power such that it's never real enough to be responsible about but always real enough to win a dispute.

Anyway I think every student should have two advisors so that everyone in the department should have to immediately know about it when a PI is floundering and have a strong direct incentive to do something about it. A LOT of my problems could have been fixed with one look with a gimlet eye from a senior, more experienced researcher being not impressed at a student under their supervision running on an endless treadmill to nothing. Frankly a lot of my problems could have been solved if my mentor had formal training or literally any supervision that could deliver metrics faster than "how close am I to my previous mentees?"

I know a lot of dual advised students wind up in a tug of war between two advisors, but like: that's the point. If one of them turns out to be insane and malicious then a) the students all have clear lines to bail, b) the other ones all realize quickly that bailing out the chaos and career damage of someone who is fucking it up is way more work than resolving the problem, and c) the one with more tethers to reality has a way bigger likelihood of formally retaining the student when and if a third party has to examine the contract.

Just. It was such a fucking waste. And not because anyone necessarily wanted it to be wasteful, either, or any malice, but because I was... mm, I think the fifth PhD student in that lab and that's actually not that many to be learning on. Systems that set you up to play with decades of people's lives should have more fail-safes and places for people to learn before they get to be the sole director of someone else's career for five fucking years, not less. And yet!

Some wip doodles, of course some needs to be fixed, fting a lot of Shadie. Mash and also Raca ( it didn't ask to be there but I do what I want to draw Raca. )

The inkling in the first drawing is for a AF attack. It's gonna be somewhat big so I'm doing it slow and steady haha.
