A lisp program will tend to have fewer parentheses than an equivalent Java program has parens + braces. They just stack up at the end of the expression.

For example, see https://gist.github.com/coding4food/1248505

Part of this is because lisp tends to be more concise, so there are fewer expressions required. There are relatively few places where lisp adds parentheses, rather than just moving them - mostly just basic operator expressions: (+ a b) vs a + b. Adding parens (a + b) doesn't make it any harder to read.

For function calls, Algol-descended languages already use parentheses and prefix notation, they just put the parens around the arguments instead of the whole expression:

(function argument list)

vs

function(argument, list)

For the adventurous tomboy: "Alanna: The First Adventure" and "First Test" are the first books in two different series.

In general a good series: Sandry's Book (Circle of Magic Series)

Some of them do have romances/crushes (Alanna series more than the other two), but they're all focused on adventurous girls doing cool stuff, and the importance of hard work, friends, learning new things, etc. etc. I loved them as a kid (and now).

US elections are at least superficially free and fair. Imho leaders that don’t hold fair elections also give up the expectation of other nations keeping out of them.

So while there is certainly back-and-forth here, I can’t see any moral issues with anyone meddling in Russian elections. It’s likely even necessary if the current regime is to be changed (which I think will be harder than in 1990).

The US obviously also meddle with more or less acceptable means in countries that do have free and fair elections but that’s a different topic.
I'm not sure why it matters if they're "a sexist".

Whether they make a decision based on internal biases caused by societal norms, or make a decision by measuring those societal norms directly and responding to them, the decision is still an expression of societal sexism.
Maybe they decided to take one company on at a time and flipped a coin and FB lost.
This whole thing is silly, and I think the google image search team brought it on themselves.

For a while, on mobile Google Image Search result pages, it was impossible to find a link to the image in its actual context in the actual site. Like, you'd Google Image search something and see something interesting in an SRP, but then you couldn't find out what it was. Maybe there was a way to do it, but the UI was too opaque to figure it out.

This obviously peeved some people off, and now the Image Results page had to pivot too hard in the other direction. Whereas if they'd made both options clear and visible, likely they never would've faced whatever internal pushback they had from rightsholders and advertisers about GISRP's terrible UI.

And now we're working around this awful UI even further.
>>use the special functions for handling hygienic macros? And each flavor of Lisp has its own way of doing hygienic macros.

There are two main flavors of Lisp: Common Lisp and Scheme;

Scheme already has hygienic macros as default; and writing hygienic macros is trivial (and easy) in Common Lisp.

>you will likely introduce a bug unless

You won't "introduce a bug" if what you need is specifically an unhygienic macro. They have their uses, so it's good to be able to write unhygienic macros as well.
Scaling retail is hard to get perfect to the same precision of auto-scaling AWS, maybe, but scaling to an acceptable (measured in profit and customer satisfaction) level really isn't. Or rather, the solution is known.

Especially in December - during prime holiday shopping hours - you staff up. It's more profitable to have a little bit of employee slack time than to have customer satisfaction way down and customers walking out without buying things.

This is a bad take - the whole "oh retail will die without self-checkout terminals" overlooks the realities of retail, what consumers want when they choose to go into an actual brick and mortar store, and how businesses can succeed. And it does so in a way that perpetuates the implication that we have to treat employees like computers to be successful.
Software related anecdote: I left a team that at one point, where an unforeseen occurrence, think something like 1 in a million happened, taking our production systems offline. Our decision makers became so risk averse to change for fear of another similar event that we completely stopped innovating and spent three years wrapping ourselves up in tape and saran wrap to protect ourselves from getting hurt again because "risk". The thing that took us down required a pretty trivial version upgrade and we never saw it again, even when creating deliberate conditions for the bug.

I ended up leaving the company, I couldn't spend another year mitigating other people's terror, the word "risk" became a trigger word, other engineers started leaving in droves and eventually, they shut down months later.
The added wrinkle to this is that the internet hides age....

So if you go to The_Donald, a bunch of the views expressed are just teenagers being awful (or normal teenagers basically), but the adults who line up with their views don't realize they how many of their peers are children.

It can definitely normalize that viewpoint and spread into the wider adult conversations. I also have noticed a few times on Reddit when someone says something insanely terrible, I will check their history to see if they are a White Nationalist or what else they are interested in, and dozens of times every post in their history is about video games. And the only time the venture out of the video game bubble it is with bizarrely hateful political commentary.

Maybe its an anomaly and if I clicked all the good posters history's they would be about video games too.... but it's starting to feel like there may be a genuine and unique culture developing around gaming that is distinctly racist, homophobic and celebrates almost any form of cruelty.

And I say that as someone who is in their 30's and still LOVES video games.
I'm not sure that Facebook already doing something is a valid reason not to do it in a new service. Quite the contrary, Facebook has validated the market for online connection, but is now struggling to find a way that to do it that is received positively by all. This could be a great time to slice off a piece of Facebook and make a new service.
I couldn't finish Foundation, after making it nearly all the way through the book and finding the only woman in the story was someone's secretary. It just felt like very, very dated and boring writing. I don't feel like all his stuff has aged so poorly, either.
I don't think people will pay for a penpal. However, they might pay for advice if the person giving the advice qualified as some kind of expert in the area in question. Perhaps you could consider an idea pivot to something similar that people would be willing to pay for.

38% of jobs could be gone by 2030 according to this report.

How do we feed/clothe/house a populace when half of the people can't work? We'll need to go back to a 1800's era system where people basically own/live/work off their own land and farm their own food, or something communal possibly? I'm curious to see how it plays out... 2020s will be pretty eventful though if robotics goes as planned over the next decade.
I find it rather more disturbing - that people rationalize explanations for various discovered "facts", and as our understanding changes and the "facts" change, just as easily come up with new rationalizations.

It exposes rationalization as story-telling.

Yes, I think authenticity is the key here.

There's no way to scale this (as a one-man show) and keep with the quality, so I'm not trying to make this a big business, just something sustainable.
Perhaps if those lower in the hierarchy and society as a whole are constantly burned by businesses failing due to incompetent leadership, they might start to expect or demand something different. Socialism? Anarchy? Some kind of socially conscious capitalism? I don't know what form it will take, but it might be something different than what we have now.

This is a terrible example. I see no reason what you just gave isnt isomorphic to

Your comment is so uniformed. Relaxing? The guy is a receiving manager. That's a physically tough job, requires a high level of organization, and he still takes time to help on the book floor by doing storytime.

A receiving manager at B&N makes around $15-17/hour. If his partner works, that's a reasonable enough amount of money to live, but not in a high COL location. How is this abnormal?

What's abnormal is thinking that this is abnormal. $35k/year isn't a high salary.
People already pay to be listened to. It's called therapy. So yes, I think people would pay for it. Perhaps someone that's just lonely wouldn't use such service, but people that are truly depressed and struggling to make it each day my give such service a try.

The problem with this services is that you are paying to have a "friend", that might says whatever you want to hear. So it would work best if it's sold as a professional service and not as find a buddy service.
Bellevue is saturated with starbucks, but very few that were open until 10PM like the one in B&N was (actually, only the Lodge and the original Bellevue store are open late). It was the place for students to hang out studying, but now...there really isn't much to replace it.
That's the influence of modernism, which was big at that time. Very much into rule by experts who applied precise, rational judgments to help or manage society. SF is still the last bastion of modernism especially in hard SF, but I think the Vietnam war was the death knell for the idea of it in culture, and the New Wave in SF for it in SF.

Barnes and Noble and Borders effectively destroyed the independent book stores of the nation, because at the time they had a better business model. I don't have a lot of sympathy for their business model getting the same treatment from the internet sales model.

It basically just uses the transponder, so it will be mode-C or mode S (ADS-B). Right now most commercial planes have ADS-B, and 100% of them will have it after 2020.

I think the main issue with FR24 is that you'll only pick up ADS-B signals within line of sight, so there may not be any receivers near KSTL. If you compare KSFO you'll see lots of ground activity on FR24:

I have a rather vivid memory from age 15 of someone tossing off a "your mom" joke to someone whose mother had just died. It was, obviously, a terrible moment.

And it was far from the only thing of that sort that happened. I remember really upsetting people on a couple of occasions because I thought about the likely, harmless consequence of what I was saying, and didn't consider whether it could cut some people much deeper.

None of us were taught to do this by gaming online. Honestly, I'm doubtful that gaming teaches cruelty any more than team sports or school cafeterias do. I get that it's depersonalizing and people say cruel things, but it feels like a boogeyman given how much actual violence gets ignored at that age.
I aggressively avoid buying books on Amazon, mostly for the reasons listed in the article, but between BAM and B&N, I will always go to a local bookstore instead. They don't grill me for PII at the register, for one.

Overall the whole experience is way better. Finding a book is a tiny bit harder (emphasis on tiny), but honestly, I'm not in a hurry when I'm in a bookstore, so I don't care.
What happens if the results are not favorable?
I bailed on high school math, thinking I'm math dumb.

In my late 20s I decided to try again, but jumped straight into calculus. And at first regretted that decision. However, I got lucky by stumbling upon this book:

https://www.amazon.com/Calculus-Made-Easy-Silvanus-Thompson/...

It "reads" like a book, with the ideas given context. I had an "ok" connection with Algebra, and the book explained the rest well enough for me.

In school, the textbooks were loaded with symbols, but not enough description -- I guess they relied on bored teachers making minimum wage to do that part. I went to a school with poor academic showings (but connections to state superintendent of ed got them a grant for football facilities).

Coincidentally, this book goes well with the technique described here:

Yes, it's pretty trivial. Ubuntu handles everything with the installation, then GRUB provides a boot menu that lets you choose which OS to use. More granular control is available to those who care, but it's still easy for those who don't care.
I really want to like this idea, I think the ideals behind it are laudable, and honestly I would fall well within its target market.

There's zero chance I'd ever sign up for such a service.

It feels artificial (It's an internet friend you have to pay for!) and self-defeating (it's a platform for shared misery!) The idea of being paired up with some other lonely person so we can vent at each other empathetically about how lonely we both are doesn't sound like it'd be a support at all; it sounds like a burden. Best case scenario is we really hit it off, and then there's one more person I like but don't really get to ever connect with for real, because long-distance. Got plenty of those already, thanks.
Okay thanks! I'll definitely send a resume when I get back home. Really appreciate the help!
In a similar vein, I've been enjoying PBS Infinite series. The original host recently stepped aside to finish her dissertation and the new hosts are doing great but still finding their footing a bit - I suggest looking at some of the older videos to get a good sense of the channel.

I remember many years ago if you were building something you'd notice the missing solutions and tools because there were things you couldn't do easily (like lightweight application-level caching before redis/memcached popularity).

Nowadays it seems like there's nothing missing.
Things like this are why I love Apple's self-checkout system at its stores. No need to even go to a checkout; just scan the item with your phone, and it's paid for.

For someone unfamiliar with power laws and scale in networks, that introduction has me totally bamboozled with multiple repeating negatives.

A scale-free network is one that follows power laws, which manifests as having specific hubs that are much more interconnected than others.

A random network does not follow power laws. Hubs and edges are distributed relatively evenly.

Is that right?

I would not go that far? In Scotland, say, Celtic Football Club hold considerable mindshare, and that is pronounced with a soft-c - presumably because the club was founded before the shift to hard-c of other uses.

But there's no noticable use of a soft-c when people refer to the people/ethnicity. Events like "Celtic Connections" are still with a hard-c. I have not noticed the use of soft-c at all, outside of sporting clubs of various sorts. I don't think that's a trend, it is just yet more of the inconsistency and irregularity that human languages are plagued with.

>>Sounds like your experience was with Emacs Lisp, a very clunky Lisp.

Emacs lisp is actually a very practical, easy to use and fun lisp to do a lot of great work in.

Richard Matthew Stallman notes:

It was Bernie Greenberg, who discovered that it was (2). He wrote a version of Emacs in Multics MacLisp, and he wrote his commands in MacLisp in a straightforward fashion. The editor itself was written entirely in Lisp. Multics Emacs proved to be a great success — programming new editing commands was so convenient that even the secretaries in his office started learning how to use it. They used a manual someone had written which showed how to extend Emacs, but didn't say it was a programming. So the secretaries, who believed they couldn't do programming, weren't scared off. They read the manual, discovered they could do useful things and they learned to program.

From: https://www.gnu.org/gnu/rms-lisp.en.html

Of course if secretaries and regular office people with no prior exposure to programming or STEM education can program Emacs using Emacs Lisp and do useful productive stuff. Programmers most certainly can.

This is more "How to study pure mathematics", when the aim is to understand how the theory is build, so that you learn to contruibute to the theory by discovering and rigorously proving your own theorems.

I don't think I've ever seen a "How to study applied mathematics". How do applied mathematicians, physicicst and engineers (who apply mathematics to real world problems) study mathematics, when they use it as a tool? How much or little emphasis do they give to proofs and theorems?

>In the end you have to see infrastructure for public transport and bicycles as a tool to increase network capacity

Prioritizing capacity at all costs makes sense in a bursting-at-the-seams megacity like New York, San Francisco, London, etc. There, sure, everyone needs to give up some convenience so that everyone else can fit. There's a point beyond which personal cars as a transportation system doesn't scale, and above that point, we need to put them down.

But much of the world doesn't live that way and doesn't want to. It's completely appropriate for smaller and slower-growth communities which have the space (i.e. away from the major cities, like parent's comment) to optimize for quality of life, mobility, detached houses, yards, etc. instead. You don't need to sacrifice everything in the name of capacity when your capacity demands are small. That doesn't mean complete car supremacy like the exurban US, but it also doesn't mean treating hours of people's lives as necessary sacrifices.
