As a slight digression, I think "mostly works" is a reasonable benchmark for a lot of software, because as much as you or I may dislike it, evidently the market won't pay for something qualitatively better. Your phone crashes every few days because most people are willing to accept junkware that crashes every few days even though it's part of one of the most expensive things they'll buy this year. I can't imagine why so many people would think that's acceptable, other than the industry successfully convincing them that it's the best they can reasonably expect, and personally I use a feature phone that doesn't suffer this sort of madness anyway, but sadly it's clear that I'm in a minority here.

If we're talking about software where reliability actually matters, then I agree that too many projects fall far short of ideal standards. I've heard all the same horror stories that probably you have. The auto industry, in particular, is moderately terrifying. But on critical projects, the kind of heavy reliance on unit tests and ad-hoc specification that is common practice and even considered desirable on a lot of Agile projects is also inappropriate, or at least far from sufficient on its own. So I'm assuming we're not really talking about the software that controls a pacemaker, the emergency shutdown systems for a nuclear reactor, or the safeguards to prevent configuring points so trains moving in opposite directions enter the same section of the track.

For most software, though, the programs that help us to do things day-to-day but if they fail once in a while under some awkward conditions it's not the end of the world, I think it's pretty clear that the industry produces a lot of value and the users would miss it if it were gone. Is it perfect? Of course not. There's plenty of room for improvement. But I think the argument that most software is bad is hyperbole.
No.

First you need to install node.

Then you need to install typescript.

Then you need to setup something that watch the typescript files and transpile them when they change. Because no, running a command everytime you change a letter in the file is not acceptable.

Then you need to integrate that in your static assets pipeline (minifiers, linters, git hooks, i18n extraction, whatever). Because files changes and are generated on the fly, and you probably use a framework that already interact with them in some way.

Then you need to make sure it's part of your deployment process, including continuous integration. Because the typescript command now must be in your builder scripts, travis files, docker container, etc.

Then you need to setup your browser to read the source map. Because debugging a transpiler without a source map is hell on earth.

Then you need to setup your IDE to understand typescript. Yeah, most editors don't understand type script.

Then you need to document that, and train yours colleagues. They don't have the same OS, versions, editors, experience than each others.

What's that, you spend 2 hours trying to help a new commer in your team on skype to find out you just don't have the same version of type script ? What's that you have a concurrency problem between several FS watchers ? What's that, somebody commited the transpiled files on the git repo by mistake and now some edge case made the travis build fail ?

Saying "it's just npm install" is disrespectful, at best. It's NOT a 5 minutes job. It is work.
That is an example of a mandatory access control (MAC) framework[1]. SELinux[1] is a MAC for linux systems and is very effective if the user doesn't disable it due to frustrations over false positives or due to true positives that are viewed by the user as false.

OSX has discretionary access control, which can be configured to be a full MAC[3].

Starting in OS X v10.5, the kernel includes an implementation of the TrustedBSD Mandatory Access Control (MAC) framework. A formal requirements language suitable for third-party developer use was added in OS X v10.7. Mandatory access control, also known as sandboxing, is discussed in Sandboxing and the Mandatory Access Control Framework.[4]

The Million Dollar Story
Fear of death is arguably either an emotion, or has a high emotional component and since autistic people do not process emotion well, they may well be far more inclined to see suicide as an option. (disclaimer: pure layman speculation)

Is a Graph DB suitable for use cases like products/homes/cars etc where users mostly do "and" queries to narrow down the results set? If so, is it faster than traditional SQL DB?

I am not familiar with how infrastructure is managed in the states but over here responsibilities for infrastructure is generally given to specific departments and they themselves generally have an understanding and a system to manage that.

The idea that you can roll in their and introduce new software to improve that management is naive at best and dangerous at worst.

The main problem infrastructure has in the states is that no maintenance is performed until it's completely broken and then it comes in very expensive. Also there is just too much decentralisation to maintain a lot of the infrastructure there.
<they installed shock absorbers>

In the SF Bay Area, such junctions of guardrails tend to be preceded by what look like huge plastic garbage pails filled with sand, apparently to absorb as much energy as possible without (or, at least, before) bouncing such vehicles back into traffic.

The other extreme was a freeway case (locals to the San Jose area can see this now, on 85 northbound in Cupertino between the onramp from 280 westbound and the Fremont Ave. exit) where the guardrail began about 10 feet from the side soundwall, leaving a car-width's gap to the right of the guardrail. A perpendicular soundwall was about 30 feet beyond.

One evening, a car went right through the gap and into the perpendicular wall at full speed.

Subsequently, the guardrail was extended at an angle to meet the side soundwall.
You're going to be doing pretty badly with half the oxygen gone even if you had no CO2.
> Remarkably, this debate has taken place based on partial and inappropriate indicators of U.S. inequality. . . . First, spending inequality – what we should really care about – is far smaller than wealth inequality.

No one really care about the exact level of inequality. They care about the trend (that inequality is much higher then it used to be). If they showed that that trend was different then what everyone thought that would be interesting, but just showing that this measure reports a different level is not so interesting.
No, but it does suggest that you could make patterned magnetic rails and riders such that you had a non-contact bearing surface. By patterning the rail and rider with gray codes you could insure that in all orientations they maintained some "push".

They would need a machine to pattern the rails though, and it would remain to be seen how durable such a bearing would be, especially if it got too warm.
This is a common and large issue in my opinion. Papers built and published without source.
There's such thing as a wrong answer, and it's pretty poor ethic to discuss psychology here before understanding someone's argument. I could just as well say that you are narrow-minded for not entertaining my perspective when I have given analysis for yours. Giving an argument about psychology which you don't want returned is bad faith. It shows a lack of regard for difficulty of good faith reciprocity.

You're basically arguing that (1) textual questions inherently have more than one answers [care to explain?], and that (2) therefore 9^9^9 is correct [can you explain if you think 100 is correct?], and as an additional tack-on point, you think that (3) operators are fair play as long as they're implicit, even though there's nothing mathematically special about them except for the typography.

Tetration is typographically written as the reverse of 9^9^9 on paper.

>NPR has advertisements on their podcasts, usually at the beginning and/or end of a show.<

I would love to see all advertising done this way--announce who makes the content possible, then get out of the way of the content...remind us again at the end where the funding came from if you wish...tasteful, dignified, makes the point, and grants recognition...

When advertising annoys people it's almost always because it gets in the way of the content...it distracts from what one is there to actually "see"...

Something so simple you'd think almost anyone could grasp the concept, yet so many advertisers get advertising completely wrong...web pages are chock full of garish flashing click-bait nonsense...

Disclosure: I am a long-time NPR listener and local station supporter...
Why would infrastructure have to be "public"? Trains and mail is partially privatized, fiber/copper entirely and still those are considered infrastructure.
I wonder how precise the alignment is? Potentially if it is low sub millimetre precision it could be very useful.
Well in a democracy, people can use whatever they like the most, but usually "open-source" goes hand in hand with "pain in the ass" and "doesn't have the user base".
There's the current one, but the girl who briefly took over for the longtime male announcer was very dull indeed.

Given the obvious downsides of Tinder-like apps, particularly the stereotypical-but-true "women are choosier than men" factor that distorts the use of them, I keep wondering how long until some company popularizes an "e-matchmaker" that sets up blind dates automatically.
I'm not surprised at all...the whole point for Amazon is ebook sales, they want install base, it's nice if you upgrade your device but many people will keep paying for books regardless of device version.

Throwing a few engineering headcount at keeping updates going as needed is more than worth it, and a more exact "when do we stop supporting this" trade-off can easily be calculated against usage and purchasing data since they have vertical integration to that degree.

This reminds me a recent interesting publication. A comment on Science (http://science.sciencemag.org/content/351/6277/1037.2.long) arguing a previous study on Science did the statistical analysis wrong is under critics that the comment itself did statistical analysis wrong.
Foraging for wild mushrooms is part of the ancient and rich culinary tradition of many European countries, where poisoning rates among those brought up in the tradition are very low. Yes reliably identifying a range of edible wild species takes knowledge and experience, but it's rewarding (in terms of both ecological and culinary appreciation), and it's only a little bit more challenging than learning to ID wild berries, for example. If you don't appreciate those rewards personally, there is no need to denigrate those who do.

For me, the flavors and textures are so varied, each suited to a different range of classic dishes, that saying common table mushrooms should suffice is the position of a philistine. I mean, bananas are tasty and plentiful, why bother with mango and papaya and passionfruit...
> Paying directly for something is better than paying indirectly. Because you consider the cost of a resource before you use it.

That does not work because it disadvantages the areas which are underdeveloped.

But Singapore is tiny and quote homogenous.

If there were no legal requirements for USPS for instance to operate all over the country then Alaska would not have a mail service at all. There are areas too sparsely populated / too poor to afford infrastructure and (federal) taxes are necessary to finance it.
<Managing these kinds of projects doesn't need sophisticated software (not that software is a bad thing, in itself). It needs competent managers.>

Indeed. California state and local governments, for example, are notoriously horrible at large software system procurement and installation, routinely paying full retail for unsuitable new infrastructure that never works and is tossed out completely, with the procurement process restarted from scratch by the next appointee(s).

Only some of these cases are reported about in the media with any degree of scope or accuracy.
"Why slowly exhale?" - So you don't increase the pressure in your lungs.

"Why is hyperventilating first bad?" - Should you hyperventilate and then hold your breath and any pressure is put on your lungs, YOU WILL PASS OUT! Don't do this!

Essentially hyperventilation reduces the blood's CO2 level. It becomes so low (while hyperventilating) that the body does not detect when the CO2 level subsequently rises to a dangerous level(while diving/holding your breath). The body fails to urge you to breathe fresh air and so you unwittingly pass out.

See the following two links for more info:

"The Choking Game: Self-induced hypocapnia":
https://en.wikipedia.org/wiki/Choking_game#Self-induced_hypo...

Deep-water divers hyperventilate and then take a big breath immediately before they dive. Sometimes "shallow water blackout" (same as what happens to kids in the "choking game) occurs, endangering the diver:

Do accidents play a role here? Everyone's always talking about suicide and the possibility of that being more common among those on the autistic spectrum, but...

As someone on said spectrum, I'd say I might be more accident prone than someone who's normal, and potentially more likely to get into trouble in general. For example, while I wasn't seriously injuried by any of it, I've been nearly hit by traffic, fallen off various things, actually been hit by traffic and done quite a few things which would probably be seen as rather 'stupid' (in an 'endangers your health' sense).

Perhaps it's possible that due to various behavioural factors, those on the spectrum might be prone to getting into dangerous situations and paying the price for them more than 'normal' people. Being generally clumsy seems to be a common trait here.

There's also a potential darker side here, in that being on the spectrum might make some more likely to end up in a violent confrontation than someone who isn't. There were quite a few news stories in the past where people with these traits have been assaulted or even killed because they did something that somehow annoyed some random scumbag. Maybe people outside of the autistic spectrum might be more likely to see a situation is trouble and stay out of it.

Those things plus the risk of suicide could all explain this difference in mortality.
I think these are indirect users. If your Android phone uses curl to download updates or something similar, then the phone owner is a user.
The reality is there is no new Microsoft. They're just trying to put a shine on a company in decline to keep investors happy. And that's easy to do with good marketing strategies like "Microsoft <3's Linux", while they are still doing the same antics to undermine Linux as they've been doing from the beginning.

Really all that's changed is they got rid of the chair throwing, vitriolic anti-Linux CEO and replaced him with a politician who knows how to work a crowd.
There are lots of problems with this article.

The basic assumption--that "spending power" is more important than "wealth" or "income"--is questionable, but the authors don't really spend any time defending it. The reason the richest 1 percent spent a lower percentage of their income is because they don't have to, and because they are able to re-invest their money (not counted as spending) in making themselves more money. The poorest 20% do not have that luxury.

The arguments about how high taxes disincentivize work assume that income == work. But that's not correct. Productivity growth has been tremendous over the last two decades, and workers have been producing more and more, but that hasn't been translating into income gains, except for those in the top 2 or 3 percent, which is precisely what the income inequality gap reveals, which is apparently why the authors of this study chose to use a different standard.

"Facts and figures are hard things. They upset prior views and demand attention." Say the people who came up with an alternative model of measuring inequality because the simpler model upsets their preferred policy, and would rather ignore the problematic numbers by creating new ones.
they're going to expect the full suite of NLP treatments with all indexed content, including code. Nope. In 30 years of searching through code, I've never once felt the need for that. On the other hand, almost every time I use Github search, I find the limitations of a word-oriented index get in the way (looking for partial keywords to find code relevant to an api, etc. It's not just special characters).

Graph DBs are great for intersection queries (AND queries). In fact, DGraph is designed to do those really fast; and supporting that via GraphQL is in our roadmap.

https://github.com/dgraph-io/dgraph/issues/1

In general Graph DBs are great when you have many "kinds" of things, which would require many many tables in traditional databases, and lots of interlinking. Those scenarios are ideal for Graphs, because many different kinds of things can be interrelated to each other easily, and be queried seamlessly. In other words, the schema for graphs is very fluid.
Your meta-question is great, but before considering it I'd like to talk specifically about your favorite example. Is it actually absurd? Sure, it's unlikely if you interpret it completely literally, but equally, "no one lives there" does not imply an empty "giant scrubland".

A more "charitable" interpretation might be that many long-time SF residents are fearful that if rents continue to rise, they (and those they associate with) will be forced to leave the city they love, and their former homes will be converted to office space and short-term rentals --- non-residential uses, hence "no one lives there".

Is there a scenario where this happens? Sure, it seems possible that tourists, businesses, and real estate speculators are willing pay more more for space in SF than long-term residents can or will. And as the city switches over to be less residential, the number of people willing to pay a premium for permanent residency may drop, accelerating the process.

The real question might be who benefits from preventing this "change" from happening. Someone who likes their current SF lifestyle would seem to have legitimate self-interest in preventing the city from changing in a way that would prevent them from continuing their lifestyle.

So at least in this case, I think people are really trying to say "We've got a good thing going here in SF, it's starting to move in a bad direction, let's not destroy what we have in an attempt to maximize economic gain." One can disagree with it, but I don't think it has a hidden agenda.
I'm studying for these boards right now, and these equations do show up. However, it's not the curriculum (at least not at my school) pushing the rote memorization of drugs, side effects, contraindications, microbes, etc. It's the board exams. A huge component of the exams is raw memorization of random facts that have no relation to anything (did you know rifampin makes your tears turn orange?). Unfortunately, there seems to be no incentive for the board examiners to change their exam.
Do you bring this up before you get the offer? You need to wait to get the offer and then negotiate an office for yourself. It is as much a benefit as salary is, though it is sad to have to call it a benefit. Once they go through the red tape and legwork to get you an offer, only then is the leverage in your favor.

Edit: sorry, it sounds like that's what you're doing already. Just re-read your post more carefully. Anyway, I wish you good luck in your search and I hope you're able to find a suitable job situation. Maybe it would help to classify this as a disability somehow? I think they have to provide "reasonable accommodation" under the ADA act but that could mean a pair of noise cancelling headphones.
They need to make the payroll, though, and that's how the system works currently. What I'm hoping will happen is a transition approach where e.g. the radio might still be interrupted but users of apps like NPR One could continue uninterrupted after paying, and they'd work out some revenue sharing deal to pay for local news, etc.

I'm not holding my breath on any of that happening quickly since you're talking about renegotiating into a new business model with a bunch of different parties.
I like NPR so I donated once. From that day forward they sent me dozens of letters in the mail asking for more money. I suspect they spent my entire donation amount spamming me.

I didn't want to agree with you. But you're not wrong.
<a city is responsible for the maintenance of its own roads>

Well, generally, but even surface streets can be the responsibility of (and under the ultimate control of) the state, county, or Feds. Some U.S. highways encompass surface street segments or cross Federal property. State routes can encompass (or be mostly) surface streets (e.g. much of El Camino Real). The Expressways in Santa Clara County (Central, Southwest, Oregon, Lawrence, part of Guadalupe) are generally county roads.

This becomes a real pain when trying to report a signal light malfunction ("not ours, call CalTrans") or a traffic issue ("transferring you to CHP dispatch...").
