" cost of delivery from solar-power-recharged inexpensive drones is going to go to near zero"

Solar electricity is much more expensive than electricity from other sources, more importantly, 'fuel' a very minor issue in the 'total cost of delivery'.

The 'cost' will be in so many other things, first off - having inventory within a 'drone flight' away from people.

I actually don't believe that drones will ever fly stuff to our door.

It will always be more expensive to delivery stuff 'by flying drone' - and 'very quickly'. See: prices for airmail vs. snail mail.

So what do consumers really need that they can't drive to the store for? Toothpaste? Books? Toilet paper? No. That won't be cost effective.

If someone 'really needs something now' - the 'cost effective' way to do it is to walk or drive down the street to the store.

Delf-driving trucks, with 'robot arms' to nicely 'drop stuff off' for the rest.
Apologies, deploying fix asap!

Good occasion to thanks all the people who have been working on Babel.

Among other things, Babel allows me to use ES6/ES7/ES8 (e.g. async/await), to write my components in JSX and to type my code with Flow.

It would be so painful to work without Babel.

Thanks guys!
All you need is a routing number and an account number to initiate a transfer of funds in either direction. PayPal and others use this as verification of account ownership by initiating a small deposit and withdrawal, prompting you for the amount.

No secrets involved.

I'd love to see a P2P style open cloud service created, where companies that use cloud services can use that instead, and then even if their company fails or has to shut down their own support of their services, their products can live on with the P2P cloud.

(Or, even if it's just an auto-graceful downgrade solution, like it hits their servers first, but if that's not available it tries the other).

For example, I once worked on a multiplayer iOS game about collaboratively writing stories based on keywords, and we were going to create a service to do it, but in the end decided to use the built-in asynchronous turn support in iOS GameKit.

Eventually the company folded, and if we had done our own service, the game would be completely unplayable. But because we used Apple's built-in services, it's still playable today, even though the company is gone, and even though the app is no longer on the app store.

That's kind of what I'm thinking, but instead of Apple providing that service, it's an Open Cloud service.

I was even thinking of writing an API to play mobile apps via email, where JSON strings of game turn data being passed back and forth via email, possibly via dedicated email addresses that the apps are given user/passwords to. Since email is a basic protocol that isn't likely to go away anytime soon, it seemed like a good tech to base that on.
It depends, but i can't help suspect that sharing the increasingly saturated 2.4Ghz band (microwave ovens, wifi, who knows what else), and being built around channel hopping (apparently this lead to some issues with US regulators) makes for a fault prone system.

This because while i have had problem on urban streets with a device in my hand and one in my ear, i have observed rurally living relatives that can walk around their whole house with the phone sitting in some corner and not suffering a connection outage.

Prove that a topological sort exists for a given graph using only linear algebraic properties of the adjacency matrix or the laplacian.

Or even, give a proof that a graph is a DAG iff there exists a topological sort using only linear algebraic operations on the adjacency matrix.

The point is, I'm sure you can do this; in some sense, we can perform every operation on a graph as we can its adjacency matrix, but why make it so complicated when there are easier pictures to work with?

Same - but with building simple sites.

I'm a designer first and foremost, have been for well over a decade. Started coding (Basic) a decade before that.

However, circumstances have led to me being more than that. I'm a copywriter, social media manager, web developer. Content manager, product designer and manager. This means a TON of switching tasks.

But sometimes, I have to do something small, like spend a couple of days launching a WordPress site. Switching between the mockup PSD and the template files, the various browser tabs where I have the CMS open, the FTP client, etc.

I've always loved keyboard shortcuts and all the tiny little hacks, hidden double clicks and ctrl+alt+right-clicks that made this go faster.

And when people watch when I'm plugged in like that, "magic" is the word most people use to describe what I'm doing. (Even some medium level devs do!)

Not boasting btw. Just happy about life in the industry. We're lucky fucks.
I think I'm still waiting hopefully on an answer to supporting more automatic polyfill imports before banishing babel entirely. (Though the big one has been an Object.assign polyfill and certainly object spread removes a lot of the need for that.)

I also would need to straighten out some things with how I'm handling TSX I think.

It's not really all bluetooth what you're describing there. Almost all of it is implementation-specific: many vendors do a sad job at implementing bluetooth, or if they buy a module as-is, they do a bad job at integrating that module.
This is the only answer. I'm self taught, but even after working with different software companies for years, side projects are always the thing that gets me my next role.
I think Apple will be the first to drop 32-bit compatibility, since they've been requiring 64-bit support in all iOS App Store submissions for a while now.

No, just the account number and routing code. It's how you associate an account with PayPal as well.

Fun bonus, both of those numbers are printed clearly on every check you write, too.
So the vast majority of doctors are condemned? That sounds like a very unfavorable environment for medical practitioners. I think its only natural to try and protect oneself.

From 2000 to 2004, in one of my country's states, 372 doctors were taken to court but only 23.9% were condemned¹. The number of lawsuits have been increasing ever since; I found a news article with more recent figures from another state but couldn't find the actual source of the numbers. It said 35% of verdicts were guilty.

That's super low pay. I would not work for that at any company; even as a student I am well aware that they are getting way more than 3k CAD from me in value.

I see no hypocrisy at all. The FSF campaigns for software freedom, not necessarily for freedom with regard to works of art. Whether software is a work of art or not is irrelevant. I'm all for public domain with works of art, but it's simply not a battle the FSF has chosen to fight.

Stallman himself has said that he has no problem with NoDerivs on his own work, or other people's work. This is why his website is mostly a "verbatim distribution is allowed in any form..." or something like that.

I see no issue here at all, and I think it's quite wrong for the author to attack the FSF over this, espeically when there are other things one could complain about (such as linking to MELPA not being allowed on the Emacs mailing list because MELPA d(id|oes)n't have the license for their JS specified as the FSF wants it.

I don't mean to criticise the FSF, they're a very good organisation in my eyes and I hope they continue doing what they do.

I have trouble believing that a Sprint-TMUS merger wasn't discussed if they were in the same room. Investors are betting that TMUS is going to get some offers within the next year.

4x range also may mean you get interference from 16x the number of other devices. In a frequency band where everyone and their dog broadcast (https://en.wikipedia.org/wiki/List_of_2.4_GHz_radio_use), that may not be a net win.
What's a hypothetical scenario that would be a problem?

I assume your company is not developing UX patents and the concern is more around developing a suite of products that use a FB library and dealing with unexpected costs or restrictions?

I would hate to avoid using what I thought were the most productive tools in anticipation of a very unlikely event. You'd essentially be paying a productivity penalty now, to try and avoid a productivity penalty in the future if you have to rewrite something.

The odds of a company like yours in a vertical getting sued by Facebook I would guess are vanishingly small.

Now if your core IP competes directly with FB I can see a little more risk because they could plausibly have strategic reasons to make your life difficult as well as a potential damages claim. However this would be a special case for only certain companies to worry about.

>"I think a lot of "rationalist" guff about super-optimizing AIs is just recycled crap we used to use religion to deal with. It's one thing to pose a thought exercise about an entity who can reliably predict what you are going to do and think 99% of the time."

What makes you think those who are interested in AI expect we will be able to predict the future with 99% accuracy? The closest example I can think of from sci-fi is Minority Report, but that isn't exactly a pure AI solution, nor particularly realistic.

The coming impact of AI will be on jobs. You don't need godlike AI in order to do human work in all its forms. That's the type of change I think will re-ignite imaginations about AI.
I don't know enough to say whether or not it's the best but...NYC is great for developers of a certain personality type. Specifically in the finance industry. There are a lot of corporate HQ's here that maintain large systems and have public and internal websites and services that require maintenance. Being friendly with Dev/IT staff at my current and previous employer, I can attest to the fact that they all say finding people who can actually code well is very tough. They seem to not think highly of college degrees, purely because the colleges are handing out degrees to people who can't code. That is the major reason they care far less about the degree. Another reason is that the IT guys in finance (and probably most places) care a lot less about "pedigree" or some kind of perceived educational status. Pretty much all of the corporate lawyers and execs where I am are all Ivy League educated. Dev/IT doesn't care about that if you can do the job - and they have easily testable methods to verify you can actually do the job, as we all know. The biggest roadblock is getting the interview in the first place if you don't have the usual background. In that case, you would probably need to know someone who works for the company to help get your resume in front of someone.

Also of note - I have seen a lot of very talented developers leave the financial companies I have worked for because they find the Dev work unexciting and they view their continued learning as stunted or completely nonexistent. They all seem to hate supporting line-of-business applications for whatever reason. That being said, it usually pays pretty well because these are business critical services that support either a large user base or are behind a large amount of money. Case in point - the brother of a friend of mine never went to college but was a self-taught programmer and is extremely talented - he works for a hedge fund running their entire infrastructure and makes more than double what I make.

If the corporate thing isn't your style, there are also a fair amount of startups here in NYC. But I don't have enough knowledge about them to comment on compensation, job stability, work culture, etc.
Scientists agree that Doudna/Charpentier deserve the lion's share of credit for the CRISPR work - if only the Broad institute could agree.
I'll throw Austin out there as the place where I met the most self-taught web developers, even with a pretty good computer science department at UT. The startup culture there is a bit more laid-back and open-minded, in my opinion, and I think this translates into giving anyone who wants to break into the industry more of a chance so long as they can exhibit competency.
Maybe it depends on the film. ;)

Comments should add to the discussion. Even humourous comments. Memes don't add anything to a discussion.
As a user i kinda like the profiles, in particular the OBEX based ones. This because it means i can expect two devices to be able to share files out of the box if both of them have a bluetooth radio. Nothing like that exist for wifi, and i have to set up some client-server scheme to make anything happen.
LolWolf, thank you very much for 'defending' the algebra much better than I could possibly have defended it myself :-)

Just to add: I don't understand why we should compare the algebra and the matrix encoding suggested above. The latter is just one possible implementation (a model) of the former. It's a good, useful model. But the point of having an algebra is that we can abstract of details of particular implementation and instead focus on the laws that all such implementations satisfy. Sometimes these laws can be interesting by themselves (at least they are interesting to me).
The Logitech 810 is a fantastic keyboard however I pretend to ignore the connectivity shortcomings that you describe...

What I would like with the Logitech keyboards and mice is an option to plug in with micro USB or to go Bluetooth, i.e. wired but detachable if your Bluetooth happens to be reliable that day.

There already is a micro USB socket for power on the 810 keyboard, sadly they don't do a mouse that charges on microUSB and can also work on micro USB. Regardless, there is not a lot that really needs to be added on the hardware side to implement such a feature.

If such goodies existed then I would not need that normal keyboard/mouse that I have in my draw for the unpaired situation you describe. I could also do things such as BIOS UEFI settings without having to reach for the emergency input devices.

Despite deficiencies, I find the 810 to be the best keyboard going, I carry mine around instead of a laptop, it works great with work PC, my phone and my home PC.

Is there a designer online to easily build these layouts? (not counting generic flex box tools)
This is interesting. I'm blind, and while I can think of ideas for products/side projects, designing a nice-looking website is such a huge momentum-killer. I mean, I know that I could just focus on features, keep the site design simple, and build a good design later. Then I visit <insert random Show HN here>, and half the comments are about how some UI element or other breaks on some combination of browser or other, and the last thing I want is to have my idea dismissed because it's ugly. I thought Bootstrap would help with this, but when my sighted GF takes one look at my attempts at site design, her first comments revolve around lack of color, and I don't even know where to begin with that. And yes, I know about themes, but sometimes that feels like I'd have to make my idea fit the theme, whereas this seems to let me pick and choose what elements I want.

Unfortunately, when asked to select a hero block, I'm greeted with a series of images. Would you consider adding alt attributes to these? If I knew roughly what they looked like, I could probably pick and choose something semi-appropriate for a given project. I don't know what other issues I'm likely to hit, but I'd be interested in providing additional feedback if this at all seems like a viable direction.

Also, just noticed I can't select a hero block via the keyboard. Items aren't tab-focusable and keyboard-selectable. Maybe this won't work at all for me, but I'd really like something between "Here's a fully-formed theme" and "Here's a completely inaccessible website builder that gives you a blank canvas and assumes you don't want to touch the final HTML." :) If anyone knows of anything like that, please do share.
Why not? Foxconn is going robotic. Their new Foxbots are good enough to assemble iPhones. So why not make them nearer to the US market and avoid tariff problems?

50,000 employees is small for Foxconn. They have 1,300,000 employees now. (Yes, they really are that big.) They replaced 60,000 workers with robots earlier in 2016.[1] They plan to replace a lot more.

I’m a very happy user of Lubuntu on an 8-year old Dell laptop – with a modest Celeron 550 processor (I only recently got around to upgrading the RAM from 1GB to 2.5GB) and intend to follow it up with an SSD.

I’ve stuck with Lubuntu for the past 5 years or so after experimenting with briefly with Elementary OS and regular Ubuntu. I’ve never had any issue installing it and/or configuring it.
I added it last minute, and it doesn't even work very well with packaged electron apps, so I'll probably remove it. I was just curious about how often it is being used.

Still no audio profile that supports Opus. Why are we still using a 20 year old audio codec (SBC) for Bluetooth speakers?

Opus is low enough bitrate that it could even theoretically be used over BLE (ignoring latency problems), while still wiping the floor with SBC.

Regardless of whether BLE transport is possible, it depresses me that Opus support still hasn't been added to the A2DP.
I moved to SF from Houston, began self learning, and joined a bootcamp. It was financially stressful and terrifying and I'm still paying off personal debts accrued, but I believe I would have had a much harder time in a different city. I was a recruiter before, and I say, go where the jobs are.

If you hop on linkedin and search "front end" and filter to Bay Area, posted last 24hrs, you should see ~1000 jobs (maybe not this month). Per Day. Every day there are thousands of jobs opened up that are very open to the idea of a self taught or bootcamp educated person. Basically, this city seems much more of a meritocratic system than Houston or Austin, other cities I'm familiar with. Also, the pay is excellent out here.

I second what others are saying about portfolios. I always say, if I asked you to make pong in your given language, you should be able to do so in a couple of hours from scratch and be able to send it to me to run on my computer/phone. That's the level you want to be at and that's the kind of apps that should be on your portfolio.

I have gone into more detail of my experience at my blog: blog.calebjay.com, and the archive section links to my older blog with some other details about my transition. I'm also happy to speak with anybody here or privately through email (see my profile) that's interested in how they can make this happen for themselves.

I moved from a crap job, a crap life (financially, I'm a happy guy otherwise), and really no future to an engineer. I went from having no future to having a guaranteed career, forever, barring catastrophic global economic collapse. I really can't express the feeling of having the weight of future-worry taken off my shoulders, but I know I want as many people that were where I was at a year ago to feel it, and I will go out of my way to help any way I can.

EDIT: Here, this link may take you directly to a search that demonstrates what I mean https://www.linkedin.com/jobs/search?keywords=%28%E2%80%9Cso...

That's the query I used in my job search, it worked quite well. Bay Area also has the highest concentration of startups and smaller companies that are notoriously open to non-traditionally educated developers. Try changing the location to Houston, Denver, Austin, Seattle, the entire state of Wisconsin, DC, etc and notice the difference. Try searching on angel.co in those cities. I think unarguably the Bay Area has the highest concentration of jobs open to self-educated developers, the question is, can you afford to live here for the several months it may take you to get a job?

I won't use Lightsale precisely because it exists.

While AWS is a great collection of services, it is needlesly complicated to use and at times very frustrating. Using it at work is fine since the span of services is so wide I can forgive the awful user experience, but if I have to vote with my feelings, I choose the service I use in private, when I pick what I like.

In this case DigitalOcean.
>Putting a comment saying just "Just another vile article", without any thoughts about why it is vile

I agree that it doesn't add to the discussion, which might be a good reason for downvoting (i.e. as a form of "quality control"). OTOH, if you happen to agree with the statement, then the ethos is that it's cool to upvote it on that basis alone. Yet, it still adds no more to the discussion.

My overall point is that agreement/disagreement as a basis for surfacing (or submerging) people's comments/ideas is a poor choice in either direction, if it's stimulating, challenging discussion we want.

>I have never tried it, still under 500 karma..

Meh. It's overrated. Can't even remember the last time I downvoted a comment (as you might've guessed) :)
