Not sure if they were the first, or whatever, but this really seems like a breakthrough technology / methodology. How many cardboard boxes do we use a day? The mind boggles.
This seems more like a replacement for Styrofoam rather than cardboard boxes, though it could certainly be used in places we already use cardboard inserts. But probably still need a cardboard box on the outside. Thankfully we can grow those too!!
> This seems more like a replacement for Styrofoam rather than cardboard boxes
It seems rigid though, more akin to cardboard than soft styrofoam. I don't see anything about how dampening it is, but from the pictures I also assumed it was more like cardboard than styrofoam. Maybe the color is deceiving me though.
Under "Features" it explicitly calls out polystyrene as what it is meant to replace, and under "Performance" they claim to provide for clients "that demand the same technical performance as the polystyrene we replace"
Nice, thanks for the link. Somehow, this weekend I’ve gone into the rabbit hole of mycelium packaging, a completely new and interesting topic for me. Need to check this out before my fascination wears off.
I don't think this is better for the environment than cardboard (if anything it is probably worse as a direct replacement for cardboard because cardboard already has a robust recycling supplychain). Rather, it is a replacement for plastic foam.
I will admit, I type exclusively on 40% keyboards. I used to have a Happy Hacking Keyboard, (in fact, the original Happy Hacking Keyboard (HHKB) with separate PS/2, Sun and ADB cables, still have the board and cables), then the HHKB USB, then the HHKB 2. One day I saw a 40%, in fact an original "minivan" by "The Van Keyboards" and thought I would give it a shot. For someone who uses the computer all day, this was an advancement over the HHKB in the same way the HHKB was an advancement over the 104:
* Your hands move a lot less during typing.
* Your hand is much (_much_) closer to the mouse to grab it.
Even though there is a slight learning curve using layers, after a short while it becomes just like the muscle reflex for "hit shift to use the alphanumerics", etc. When I have to run into the data center or go somewhere and use a "real" keyboard for a moment, I am reminded of just what a huge time difference it is to grab the mouse, or reach for keys like PGUP/PGDWN, etc. It may not be for everyone, but I advocate for giving small keyboards (even split ones) a try.
I feel most people could get like 80% benefits with simple key moves rather than macroing:
* add column of common movement keys (pgup/down/home/end) on the left side
* move entire numpad block after that (so its leftmost)
* remove the spacing between the top level FX/esc keys
if you don't need arrows, that immediately puts your mouse good 6.5 cm closer
I especially don't get losing the numeric top of the keyboard but that's mostly because I actively use the Fx keys for window navigation (one window per key,capslock+ 1-9 get the left monitor, F1-9 get the right).
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?
This isn't true right? You really can bring in zero dollars in grants and phone it in in the classroom. (Now, literally on Zoom!) I don't think it helps to pretend that everyone keeps pushing hard post tenure.
But, I think most people do. The system is deliberately designed to push an assistant professor so hard, that when they get a permanent contract, they're conditioned to keep pushing. It typically succeeds.
Yes; you can phone it in post-tenure. But just because it is possible doesn't mean (in my experience) it is common; and I don't think it's helpful (as TFA claims) to equate this possibility with "a total scam." To get tenure anywhere doesn't just require a huge amount of work as an Assistant Professor; it also requires a huge amount of work as a PhD student and potentially multiple rounds of post-doc'ing or other non-tenure-line work. In my experience, tenured professors have spent nearly two decades distorting their work-life balance beyond all recognition to the point that grinding insanely hard in pursuit of publications just feels normal.
IMHO the HP 15C RPN is the best calculator ever made. I still have the original with the slip case and manual. However, more often these days i just use my phone's calculator without RPN (i don't need to do a lot of complicated math for mechanical engineering -- we use tables for most stuff). I reached a point/decision several years ago to protect my HP 15C for posterity.
I can't think of another electronic device that has survived and remained useful for half the 43 years my 15C has - through two years of high school, a math degree, and an entire software engineering career. When I calculate something any other way, it involves thinking about what my thumbs automatically do on my 15C and translating that.
When I'm away from it, there's a wonderful emulation of the 15C (and 16C) at https://jrpn.jovial.com. The numeric algorithms behave identically as far as I can tell, and it even includes the back panel (3-dot menu near the logo, then "Help"). The visuals make me feel right at home. If only they could reproduce the tactile experience.
I have some generic Sharp calculator with an apparently-immortal battery and a nice multiline display. It has all sorts of fancy functions that I never use. Apart from that, everything the OP said.
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:

Random Matrices, Spectral Measures, and Composite Media.
"We consider composite media with a broad range of scales, whose
effective properties are important in materials science, biophysics, and
climate modeling. Examples include random resistor networks, polycrystalline media, porous bone, the brine microstructure of sea ice, ocean eddies, melt ponds on the surface of Arctic sea ice, and the polar ice packs themselves. The analytic continuation method provides Stieltjes integral representations for the bulk transport coefficients of such systems, involving spectral measures of self-adjoint random operators which depend only on the composite geometry. On finite bond lattices or discretizations of continuum systems, these random operators are represented by random matrices and the spectral measures are given explicitly in terms of their eigenvalues and eigenvectors. In this lecture we will discuss various implications and applications of these integral representations. We will also discuss computations of the spectral measures of the operators, as well as statistical measures of their eigenvalues. For example, the effective behavior of composite materials often exhibits large changes associated with transitions in the connectedness or percolation properties of a particular phase. We demonstrate that an onset of connectedness gives rise to striking transitional behavior in the short and long range correlations in the eigenvalues of the associated random matrix. This, in turn, gives rise to transitional behavior in the spectral measures, leading to observed critical behavior in the effective transport properties of the media."
In this lecture we will discuss computations of the spectral measures of this operator which yield effective transport properties, as well as statistical measures of its eigenvalues.
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.
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.
Totally cool stuff.
