You're lonely if you have solitude but want social interaction.

It's very easy to enjoy solitude if it's only temporary. If during that period you lose the friends you had, eg moving country, it can be very hard to build up connections again.

Then if you do want social interaction again, suddenly you can't have it and you become lonely.

So don't be too smug about enjoying solitude. Don't lose the important interactions as you never know when you'll need them.

The amount of time involved here matters. Do you enjoy solitude for a week/month/year/decade. Do you want that solitude when you're 80?

We think bridges are a very well explored domain. Then something like the Tacoma Narrows incident happens, and we realize how much of a fallacy that really is.

Bridges are unique to their locations and their scale: what works over a creek will not work over a ravine. What works for a pedestrian will not work for a car. What works for a car will not work for a train. What works for a train will not work for a marching army.
Thanks for this post and clear explanation
I think therein lies the real reason why personas (often) fail - no one establishes the connection from the personas to the types of user / customer segments companies will have already established, from analysing their sales data and usage analytics.

By contrast to something like A/B testing, which can produce actionable results, in my experience personas frequently end up as nothing more than MeetingWare, so that everyone attending "can be on the same page"

"zen to aku" is a common Japanese expression that means "good and evil". It also means "wholeness" and "everything", among a bunch of other meanings (not all spelled with the same character, but pronounced the same). Zen is a very broad term in Japanese, that probably encompasses the western notion.

This isn't really a fair comparison: trusty old DGESV will yield far more accurate results for badly conditioned problems since it does row swaps (partial pivoting). It might also rescale values; I don't remember the details. It would be much more reasonable to compare a hypothetical DGEC (double precision general matrix cramer's rule) routine.

Yeah, some of the requirements do not seem well thought out. I've passed the EIT and PE exams but not the FE exam. I have two engineering degrees, but let's say I had a math degree.(If I recall correctly you can take the EIT/FE/PE with hard science or math degrees.) I wouldn't qualify for the patent exam. That said, all these licensing exams are about jumping through hoops- find out the requirements, and finish them.
This reminds me of a scathing and hilarious blog post about personas from 2013, where I actually first came across the concept:

As I read it persona is more of an attempt at characterizing the mindset/psychology of the end user.

Your description of persona is more like a user role serves as a grouping of use cases or user stories (which is still very useful!)
Inside a library book, I found a printed-out email from one author of the book to the other, about the book.

The book was Programming in Prolog by Clocksin and Mellish, in the library of the University where Mellish was based at the time of the email.

The email is dated 1988; I found it about twenty years later!

The piece of paper also has the name of another academic handwritted on the other side.
This is a very.. immature and amateurish response at best, purposely deceptive at worst.

Their older article of matching personas with Jobs-to-Be-Done has always been a good one: https://www.nngroup.com/articles/personas-jobs-be-done/

It also depends where you use these. While personas are often low value in product design and UX (where JTBD can shine), in marketing and sales personas can be a big help (although even there, JTBD has strong role).

OT: who are the crypto people you follow? And on which channels?

Twitter seems sadly popular among this crowd. Sadly because it lends itself to flamewars.
This submission is here because of the link to the intro to OSes book[1] by one of the Clive authors that was posted yesterday. It's worth taking a look at the other stuff referenced on this page page, as well as the author's other links.[2]

To answer your question:

> Better performance? Could be.

That's one aspect. If you follow the link from the Clive page to its predecessor Nix[3], its tagline is "high performance cloud computing is nix". A current (2018) justification for that project can be found in the form of an abstract for a paper with the same name[4].

But then the other part is given away in the abstract for Clive itself: "Clive introduces new file system technology and novel interfaces for the construction of networked system"[5], which is another way of saying that this is blue sky research, which is itself a codeword for we decided to try out a bunch of things purely _because_ they're different and want to see if anything will come out of it. Notice how the screenshot here shows the OS shell is some sort of acme-like[6] made to run in a web browser, for example.

To repeat my earlier remark, the author's other pages are well worth a look. For example, don't miss this[7] page chock full of links to research OSes (although many of them are dead). Or there's Picky[8], which looks like what you'd get if you took Pascal/Oberon and more or less did a transliteration so that the grammar gives you a curly brace language instead of a wordy, shouty one with BEGIN, END, etc.

Part 4 explains the Curl-P part in more detail, and it doesn't inspire any confidence. They are claiming that they intentionally inserted a known bad hash function in the open source part of the code, so that anyone "fraudulent" clones would be useless. The closed source coordinator is claimed to avoid this problem by some way, so they claim that the IOTA network is not affected.

I'm having a very hard time believing that explanation, but even if I do, it's still something that shows bad judgement in my opinion.
My first solution would be improving reader security by starting with one with decent code (Espie suggested MuPDF), compiling it with something that makes it memory-safe, and running it in a sandbox on separation kernel (eg Genode or Muen). Then, a memory-safe conversion tool turns it into something more trustworthy. This might even be batched on simple hardware which itself has lower attack surface. Later on secure hardware like CHERI CPU albeit that can happen today if you have FPGA board and skills to run their HDL code.

For fun, though, I'll dust off an old concept since you're talking printing. One might start by printing them to a virtual screen like in Nitpicker GUI with the untrusted reader. Aside from isolation, there could be a feature to convert what's on the virtual screen or page into a compressed image. A PDF with N pages becomes a zip of N images or a single image of some size. That itself could be distributed to run in the trusted, safe viewers we already should have, right? ;) It might also be run back through similarly-deprivileged OCR to turn into a safer format. Gotta eyeball it if doing it that way. That said, there are fonts that work well with OCR that it might be converted to as part of image production if OCR is the goal in the first place.

Could be a fun, little project teaching folks about a number of topics at once.

I'm not a browser expert, but my understanding is that JS is still single-threaded in the browser, despite allowing asynchronous functions.

3d printing is incredibly powerful for hobbyist electronics- you can make professional quality stuff[1], only limited by your creativity and design sense. Home FDM printers are so good that you can 3d print working threads even on cheap machines! If you spring for a more expensive lithography or sintering machine, the parts are effectively indistinguishable from commercial parts (aside from obvious technical differences like the lack of witness marks).

The prices are just ridiculously low now as well. $160 + tax and shipping gets you a printer[2]. Obviously you pay for that in terms of continual fiddling and reduced quality (and the $220 MP select mini is probably a better choice), but even that's better than how it used to be. $600 will get you nearly hassle-free prints and $750 will get you one of the best printers on the market[3] (well, almost on the market). Arguably the new Prusa is the best option out there- right now it has features that no other printers do, certainly not with the same build size. Really impressive bit of kit[4].

IMO 3d printing is legitimately at the point where if you're making things at home, a 3d printer should be on your list of tools to buy even before a mill. Obviously it depends on what you want to make but it now takes way longer to learn and use modeling software than to set up and tweak your printer.

This is because professional licensing occurs at the state level in the US. While there are legal credentials at the Federal level, there are not Law Licenses. The same is true of CPA's and the IRS has a test/certification for Enrolled Agents that have the equivalent status of CPA's in terms of representing clients in tax matters.

Yes there is. If you believe the wavefunction is physically real, then two different wavefunctions should correspond to two different physical realities. As I said, it's far too magical a coincidence for these two very different ensembles to not be experimentally distinguishable.
Their argument for using ternary is that it is 8 times more efficient than binary and it is very important for iot devices which need to be have low energy consumption and a long life. Whereas the conversation from ternary to binary would add only a 10 % additional usage.

They are trying to push the ternary to see if adoption can take off. All it needs is a few thousand logic gates on any traditional chip.if it doesn’t get adopted,they said they can always go back to binary.
The name is certainly misleading. Green threads (greenlets) are a totally different concept entirely.

This is really a util method to simplify the call syntax for a web worker.
These kinds of tricks certainly are more pleasant to do in languages with real metaprogramming support.

For numerical applications, one interesting project that comes to mind is the Terra programming language. It uses a flexible high level language (Lua) to metaprogram a fast and predictable C-like language (Terra). The advantage compared to the examples you mentioned is that each language can focus on its strength: the low level language being similar to C allows the programmer to better reason about performance and having a high level language for metaprogramming keep things simple.

https://terralang.org

There are also systems out there specifically designed for numeric applications that let you specify an algorithm in a high level DSL and generate highly performing C code, some of which might even tesr various versions of the code to find one that runs better on your machine (for example, the best way to iterate the data might be affected by cache sizes). I don't remember the names of these off the top of my head but the Terra PhD thesis has lots of references to them.
Hi TipVFL, thanks for the comment. Stylepill is not optimized for mobile, we are focused on the main functionality right now (we are a team of 2 people). We don't want to optimize a product that nobody wants to use. Our main goal right now it's that the people love Stylepill.

Years ago System Shock 2 had a demo which was basically just the introduction to the story, and the new Prey recently was similar. Both lead to me purchasing the full game almost instantly after completing the demo.

Thanks that's quite interesting. Your results of seeing higher startup costs definitely mirror my experience.

When I need constraints on CMA-ES for real world stuff I've been using a simple equation to map the output of the parameters before using them:

y = a + (b - a)*(1 - cos(pi * x / 10)) / 2

Where a is min, b is max and x is the unconstrained input value. (I saw some random paper recommending this years ago and have been using it ever since).

If I get a chance today I'll try and run your code and play around a bit. Really cool stuff!
Oh MAN this is exciting! And I realize it's the first Falcon launch in some time where no one is confident it won't blow up. The Falcon 9's record of flights and landings in 2017 were so consistent it almost started to feel "normal". But not anymore!

I sure wish I could see this one in person. Maybe one of the later Falcon Heavy flights once the hype has made the tickets more accessible and affordable. Heck, last year I was able to get to see a Falcon 9 launch for no additional cost beyond admission, so maybe it won't even be that long.
This is true! Nice username, btw!

I think some of this comes down to how closely you have to mimic a human rider. Does the robot have to weigh as much as a plausible GP rider? If not, then the robot plainly has a mass advantage. Would that be counteracted by the robot's inability to shift mass and drag knee/elbow like a Rossi or Marquez can? I actually don't know.

Heck, on Windows I couldn't even rename audio/video files when playing them in an app, but I can on macOS, without anything crashing (except some stubborn Windows-logic apps like VLC which will fail to replay something from its playlist that has since been renamed, but at least on macOS it will still allow you to rename or move the files while they're being played.)

It's small details like these that make so much difference in daily convenience.

The criticism that opened my eyes to the issues with Personas was this example from Alan Klement:

> Why did Alan buy the Snickers candy bar?

A. Alan is a thirty-five year old; has a degree in marketing; likes peanuts, chocolate, nougat, and caramel; loves Snickers, eats one every day; has an active lifestyle; drives a Honda; aims to retire from age 55

B. Satisfy his hunger

---

My other insight was that many UX firms treat artifacts like Personas as the deliverable. It is something concrete to show the value of the time and money spent doing research. But it is a deliverable that has almost no value to improving the product. The point of doing user research is to improve the product, not to produce a beautiful 20 page "research document". But translating user research from interview into fully-realized and delivered features is hard, and emailing a PDF of personas is comparably much easier.
