> Agree, but edge case.

This is by no means an "edge-case" if you live in a rural area. "Sound policy" within a heavily urbanized area may be unworkable elsewhere.

> Can't base sound policy at scale on the stars aligning

"Failing to scale" here would be to allow urban population centers to dictate policy that would be untenable in other areas of the country.

Even building a cube-sat that never leaves your desk would be an interesting hobby project, really. Non-experts would certainly learn a ton from doing so, and you'd end up with a cool conversation piece, if nothing else.
chrisallenlane··on BitTorrent inventor announces eco-friendly Bitcoin competitor Chia
I'll note here that at least one "proof-of-capacity" coin already exists:

http://www.burst-coin.org/

I can't elaborate either on the merits of proof-of-capacity vs. proof-of-capacity plus proof-of-time.

I'll add Gridcoin, which is a cryptocurrency that rewards BOINC participation:

http://www.gridcoin.us/

I really wish coins like these would catch on more than they have. Proof-of-work is, to the best of my knowledge, the only system that provably works. If we could just harness that computational power to do useful work, we'd be in a great place.

chrisallenlane··on Show HN: Wit-cms – a flat-file, blog-aware, publishing platform for Express
Hi, HN. I'm the project author.

I wrote this CMS a few years ago after having become dissatisfied with both Wordpress and Jekyll. `wit-cms` is an npm module that attempts to split the difference between both of the former, in that it reads content from markdown files, yet provides Wordpress-like taxonomies.

`wit-cms` does not generate static HTML sites like Jekyll - it is not a "site generator". Rather, it parses page/post markdown files and stores their contents in RAM as properties of a JavaScript object. As such, deployments are less "messy" (in my opinion) than with Jekyll, and page speed times are good even without using any kind of server-side caching.

`wit-cms` has no administrative backend, and thus has a small attack-surface. I personally publish new content using an npm script and `git pull` over SSH.

In my opinion, `wit-cms` is great for technical users (which are comfortable using command-line tools) that maintain small blogs. I have thus decided to share the project here.

I hope some of you find it useful. Feel free to ask questions or share feedback. Thanks.

One thought regarding monetization:

I assume you're loading ads via JavaScript or something. (I didn't check.) I too saw the notice regarding blocked ads.

It will be a cold day in hell before I disable my ad-blocker, but you can easily manually insert affiliate links as well.

If you sign up for the Amazon affiliate program (which I assume you did), just navigate to the item you're trying to sell, click the "get link" button (or whatever) that Amazon provides for you, and you'll get a nice, shortened affiliate link.

In my opinion, that is a really clean way to do things - you can just create a plain-old HTML list of affiliate links. That gives you a mechanism for monetizing your site, and doesn't require me to disable my ad blocker to support you. Win/win! :)

chrisallenlane··on How flying messes with the mind
Fellow flight-o-phobe here.

> "You are less likely to be in an accident in a plane than in a car".

> The above is a true statistic, but more nuance is required.

Regarding the "nuance": something I've never seen before, but would like to see, are these risk numbers adjusted for drivers that are not at-fault.

Example: If I have a reported N% likelihood of being killed in a drunk-driving incident, but never personally drive drunk, is my personal risk-exposure really N%? It seems like it would be lower.

My instinct is that these blanket-statement risk numbers may overstate risk for competent drivers. Not so on an airplane, however, where passengers have zero influence on how an event may play out.

I understand that you didn't write anything professionally about your trip, but did you ever write anything casually about it - blog posts or the like? It sounds like it would make for interesting reading :)

chrisallenlane··on A Philosopher’s Take on Global Basic Income: Fund It by Land Value Taxation
Too late to edit, but: s/hand/land/
chrisallenlane··on A Philosopher’s Take on Global Basic Income: Fund It by Land Value Taxation
I'll concede that I'm not as economically literate as I'd wish, but this doesn't make sense to me. The "1%-ers" don't tend to store their wealth in land, do they? How would this proposal even out the wealth-gap when it is essentially blind to the mechanisms that the rich use to store their wealth?

If anything, this idea seems like it would only harm the (already struggling) middle-class, who may have little equity beyond their home/hand.

I've noticed this on many other news sites recently as well. I hope this trend dies soon. This is an immediate "close tab" for me when it happens.

I'd probably watch this. I wouldn't _drive to a theater_ to watch it, but I'd watch it on Netflix.
chrisallenlane··on Taking meldonium for performance enhancement
I'm with you on this. I'd be really interested in seeing, for example, an "Open Division" in Track-and-Field, whereby anything goes, up to and including gene modification and cybernetic enhancement.

It would be both a sport and a laboratory for transhumanism. I'd be incredibly interested to see what science came out of it.

There are probably ethical arguments to be made against doing that, but... meh.

chrisallenlane··on Doomsday planning for less crazy folk
I wouldn't worry about this for an "emergency" supply - especially for a small supply like you'd be able to keep in your car. If you break down on a hot day away from town somewhere, I'm sure you'll be glad to have a gallon of water with you, BPAs be damned.

There's Gridcoin, which, if I understand correctly, is essentially the "coinification" of BOINC:

It would be great if it ever became profitable to mine this.

Glad to help :)
chrisallenlane··on Whatruns: Identify technologies used on any website
FWIW, none of the static media (images, css, js) seems to be loading for me - I'm just getting a bunch of 404s. This is happening in all browsers on my system, including when plugins are disabled.

Might be network weirdness on my end, I dunno. (Or a HN "hug of death"?) Anyway, wanted to let you know.

Congrats on the project :)

> in the US you could imagine an insurance company that competed on lower premiums conditional upon certain gene edits being applied to covered children.

On one hand, this sounds entirely economically reasonable (and even humanitarian).

On the other hand, I fear this would inevitably produce unintended consequences that would shape our society in distopian, sci-fi/horror-flavored ways.

I have no idea how it would actually shake out. Maybe I'm just being anti-intellectual here.

Thank you for the explanation. This is entirely counter-intuitive to me.

For what it's worth, we do have PBS ("Public Broadcasting Service") over here, which is funded via a combination of taxes and donations. A lot of folks dismiss it as being "left-leaning", though.

> citizen impact per employee.

Do you think it would actually possible to quantify this in a way that:

1. Accurately represented "reality"?

2. Couldn't/wouldn't be gamed?

Seems challenging to me.

chrisallenlane··on Teller – API for your bank account
It seems like they would only find out after the update has been pushed, though - ie, after the app has been broken.

Unless they have relationships with the banks now, and would be given a heads-up. Perhaps that's the case. It sounds like it may be.

chrisallenlane··on Social media bubbles may threaten democracy
> First, the lack of a real threaded comment system.

> Second, the lack of a dislike/downvote, particularly an anonymous one.

I don't know. I agree that Facebook's commenting mechanism is ill-suited to deep discussion, but isn't the mechanism you're describing more-or-less exactly what exists on Reddit? And people are certainly able to self-segregate into bubbles on Reddit.

And for that matter, at least anecdotally I'd say that most of the political "discussion" that occurs on Reddit is low-quality, in that it tends to devolve into users shouting "fascist" or "cuck" at each other. (Some subreddits are better than others, admittedly.)

I suppose that Reddit users typically don't know each other in meatspace, though, and that Facebook is (mostly) different in that regard. Maybe that would make a difference. I don't know.

chrisallenlane··on Social media bubbles may threaten democracy
> Here's the remarkable thing - this doesn't seem to be affecting my feed at all. I get as much politics as ever. I couldn't tell you how many times I've informed Facebook not to show me Trump news, and it's still there, lots of it.

During the peak toxicity of the election cycle, I unfollowed a lot of sites/sources/people on Facebook. For a while, it worked.

Eventually, though, I simply lost that ability. For the last few months, if I click "unlike" or "unfollow" on some source I'd like to be rid of, nothing happens. I'm literally unable to unfollow content on Facebook now.

If you Google around, you'll see that this is a common problem that people have been reporting for years.

This makes me wonder if this is a bug, or if, perhaps, the Facebook algorithm simply refuses to allow me to have fewer than N number of connections to other nodes or something.

> Russia embarrassed us with their sophisticated cyberwarfare capability in the last election

I'm still unclear how "sophisticated" these attacks were. Per the unclassified information, all I've heard mentioned is:

1. social media manipulation

2. traditional media manipulation (RT)

3. email spearphishing

None of the above strikes me as particularly sophisticated, even if it's potentially effective. (I don't know if it was effective or not in the case of the election.)

Of course, I have no idea what the classified information says regarding any of this.

chrisallenlane··on UBeam's Meredith Perry shows her wireless charging technology really works
Yeah, I had the same impression.

I'll concede that I probably use my phone less than a lot of people, but this looks like a "solution in search of a problem" to me. I'm still using a Nexus 5 that's several years old, and my battery rarely drops below 80% over the course of the day. (I only charge my phone when I sleep, and never "top it off" during the day.)

When I do need to charge it, I plug it in, and can get a full charge in about an hour, if I remember correctly.

Even if we were to assume that this product is viable technologically (which is a big "if"), my hunch is that it won't be viable commercially for much longer as advances in battery and phone technology make it irrelevant.

chrisallenlane··on ElectronConf postponed until a “more diverse slate of speakers” can be delivered
> Suppose a female new grad goes to Electronconf and sees all male speakers. Suppose she goes to other conferences and it's the same story.

How does cancelling the conference help anybody? The minority of women that may have otherwise met and inspired each other no will no longer meet. Everyone is worse off.

> Once the cycle of people being motivated and seeing others like you starts, you see a diverse set of candidates joining the industry.

Do you think this really applies in the computer industry? I've been doing this for a while, and at no point have I had - or cared to have - any heroes to emulate. I work with computers because I like computers - not because I like people!

chrisallenlane··on The Turing Tumble lets you and your kids build real mechanical computers
You're probably right.

It looks like this project might raise well above the $48k, though. (It's at $108k as of now.)

I recognize that this can be both a blessing and a curse when it comes to Kickstarters. With regards to NRE, though - hopefully it's straightforwardly a good thing.
