readingnews commented on Tenure Is a Total Scam (2023)   betonit.ai/p/tenure-is-a-... · Posted by u/barry-cotter
readingnews · a day ago
I worked at 5 universities, two of them in the top 50, and I do not know of one tenured professor that "does nothing" and "publishes next to nothing". Some of them teach very little, and that may have been for the best, but all tenured professors I was aware of needed to do research, bring in money (or you were, yes that's right, fired), and teach.

Granted, I worked in STEM fields. Maybe this author does not realize what it is like in the physical sciences or engineering?

I have an old HP 15C RPN scientific calculator.

- I know where the buttons are without looking.

- It has functions my Android calculator does not have (directly or that I know of).

- It has a strange satisfying tactile feedback.

- It never interrupts me. Ever.

- It never distracts me. Ever.

I reach for it frequently.

Not sure why you have to read 3/4 of the article to get to a _link_ to a pdf which _only_ has the _abstract_ of the actual paper:

N. Benjamin Murphy and Kenneth M. Golden* (golden@math.utah.edu), University of Utah, Department of Mathematics, 155 S 1400 E, Rm. 233, Salt Lake City, UT 84112-0090. Random Matrices, Spectral Measures, and Composite Media.

The claims sound somewhat exaggerated, 5kw of subwoofer is nothing in live music venues, though they purposely don’t go as low. Here’s some more modern “big” subs, which are larger and can radiate significantly more power

Thanks for the links, that is a company I did not know existed, and the woofers are interesting. Really makes you wonder if they have overcome the traditional problems of large woofers. The Fostex super woofer users recommended rotating it once a year due to its own weight possibly deforming the spider structure of the woofer, at only 27" across. 60" or 100" across is back to the future level ridiculous. As another poster said, I can not see this outperforming several smaller units, but I would love to see/hear it in action.

readingnews commented on It's hard to build an oscillator   lcamtuf.substack.com/p/it... · Posted by u/chmaynard

It is hard to put into words how so many people "out there" can print things, have people read them, and they are so worded that the average person is probably reading this as "the truth".

> but it’s rather difficult to build a good analog oscillator from scratch. The most common category of oscillators you can find on the internet are circuits that simply don’t work. This is followed by approaches that require exotic components, such as center-tapped inductors or incandescent lightbulbs.

It is not hard to build a good analog oscillator from scratch, we have been doing this for decades. Secondly, while an incandescent _might_ be considered exotic, and completely unnecessary for an oscillator, a center tapped inductor is totally not exotic, and also, not really necessary for an oscillator.

As others have noted, it is simple to build a really good analog oscillator. This article is blah, and "meh" at best.

Take a look at salary reports from places like https://www.levels.fyi/2024

If you think $124k a year is high compensation for someone with 17 years of experience in Portland, your compensation expectations are way off.

Wow, I read your informative link. Where are these jobs? I went through a round of interviews last year for Sr. positions, across a number of locations in the U.S., and quite frankly, the average salary for the positions interviewed for was $80k less than most of those in the list, and $230k less than the SWE manager in the list.

Oh, and since he's a public employee, you can look up the current salary and history.

https://hr.oregonstate.edu/sites/hr.oregonstate.edu/files/er...

https://www.openthebooks.com/oregon-state-employees/?F_Name_...

I'll summarize it:

$107k in 2017 and $124k in 2023. I don't know about you, but someone with 17 years experience could easily be making 2-5x that depending on the company and role.

I have indeed lived life wrong. I work in HPC as a Systems Engineer (right now, in 2025, with graduate degrees in engineering, and 25 years of systems admin / engineering experience) and do not make what this person made in 2017, much less in 2025, OR 2-5x that amount for that matter (total dream salary, geez)... at one time I was the data center manager and teaching CS classes, at the same time, working 80 hours a week.

How the heck do these people secure these high paying jobs? There is some club, and I am not in it. Sorry to rant, but that 1FTE salary is huge.

"Graduate degrees" listed as a reason.

Yes, designing chips is hard, it takes a lot of knowledge. This is why medical doctors need to go through all that schooling... designing a tiny chip with more transistors running software that does amazing things is very difficult.

My Ph.D. is in computer engineering, specifically VLSI and chip design. This was from a few years ago. I _probably_ should have gone into industry, I mean, after all, it is what I went to school for and wanted to do. However, the starting salary for a chip designer (Intel / AMD / HP / IBM) was literally less than I was making at a side job (I worked my way through my Ph.D) as an IT sysadmin. Not only that, people that I knew well that graduated before me would call me up and tell me it was worse than hell itself. 80 hour weeks? Completely normal, outside of the 2 hours of commute time. Barely make rent because you live in California? Check. Pages / Calls all hours of the day outside of work? Check. 80 hours? You mean 100 hours a week leading up to a release, right? Check.

Looking back on it, it seems this was "the challenging" and if you made it past this (something like 5 years on) things calmed down for a chip designer and you moved into a more "modest" 60-80 hours a week role with less pressure and somewhat of a pay increase.

Yes, how do you attract talent under those conditions? It is not flashy work, takes a lot of schooling and the rewards are low. At least medical doctors can kind of look forward to "well, I can make _real_ money doing this", and have the satisfaction of "I helped a lot of people".

I was wondering if it got harder or if it's just random:

    function generateColors(difficulty, blacklist) {
        ...
        let sample = Math.floor(Math.min(Math.max(0, 1-Math.pow(1-difficulty, 1.5)), .99)*5);
        let distance = (5 - sample)/5;
        ...
    }
    function setupRound(blacklist) {
        ...
        const data = generateColors(currentRound/totalRounds, blacklist);
        ...
    }
Plotting that first magic: https://lucb1e.com/randomprojects/js/testformula.htm#%24%28%...

    round#  difference
     0-- 2  5
     3-- 5  4
     6-- 9  3
    10--13  2
    14--20  1
The "blacklist" parameter prevents that you get the same challenge twice. Note also that it submits every answer to the server (fine imo, but I think it would be even nicer if this was mentioned on the page)

Thanks for posting, I thought the same thing... my (useless data point of one) results showed 100% accuracy except the last four, which I thought "wow, I am just guessing now, can literally not see a difference".
