We are somewhat far away from being restricted by the size of single atoms.

A silicon atom is 0.2 nanometers and the smallest single transistors used in recent chips is in the order of 5-10 nanometers.

Also, using photons instead of electrons does allow you, almost literally to handwave away he size of atoms. How exactly, is unknown today.
Sorry, I didn't see this comment until now. I agree that the bank and the lawyers as a whole are trustworthy. That is not the same as each individual within those banks and lawyers office being trustworthy. And the one I particularly dislike is the real estate agent who I didn't even get to chose as they are an agent for the seller.

Copies of these verification documents are hugely valuable to someone trying to carry out "identity theft". They could for example forge an 'originals seen' stamp from a lawyer or bank teller. At that point they are as good as an original as far as banks are concerned.
I wonder if IPFS can be connected to Cloudflare such that CF ends up acting like a CDN for IPFS network. The content is encrypted (so that the CF does not know what's being served) and users can offer their own Cloudflare API keys to take part in the network.

I used to love reading the Maplin catalogues when I was a kid in the late 70s and early 80s - rarely used the shops though - they mostly seemed full of rather tacky electronic toys/gadgets rather than components.

20 is a low number. A full bus holds about 40 people and a packed one 75-80.
You are exactly talking about percentages.

B/A is the percentage of the new value relative to the old.

(B-A)/A is the percentage of the increase of the value.

This is algebra not English.

1) You start out with one rock.
2) You add another rock, getting a pile of two rocks.
3) The rock pile size is now 200% of the original size. But, the increase of the rock pile size is 100%.
4) According to the rules of algebra, 100% = 1. In this case 100% = 1 rock, since the unit under discussion is rocks.

Conda is like pip

Conda is more like pipenv in that it does both package management and environment/version management. And while it's true that not every python package is in conda, that vast majority are and conda and pip play nicely together if you want to use pip to install some packages.

Also conda can be used to install both surrounding tooling (like gcc and make, super useful on Windows) and, in many cases, build dependencies and necessary C libraries. Something pip doesn't handle. Doing for example "pip install gdal" will very likely leave you chasing down third party dependencies, while doing "conda install gdal" will just work.

Finally, conda has recently added R support. So you can now manage your R packages and environments with the same tools as python. Super handy if you have project that uses both R and python.
Communities engage in forms of exchange. If I were using this to communicate with other members, for example interested in retro computing, it'd be nice to have a way of exchanging hardware with each other, with some kind of economic exchange to fit.

Its not unreasonable to give people - no matter whether their intentions are commercial or otherwise - a means of safe exchange of value, without commercialising that exchange. Or, is it?

Ask HN: How do you make apps?
We've been building hybrid-apps at work for a couple of years (Cordova) and are now feeling the pain of those hybrid eco-systems. Unmaintained plugins, flaky behaviour between iOS and Android, difficult to develop and unit-test, etc.

Apps we made earlier started out pretty basic, but soon started to grow bigger with login functionality, placing orders and interacting with a community.

I've started looking at alternatives and found a few. What do you recommend/use at work or for you personal projects?

Xamarin? NativeScript? React Native? Pure native (swift/java)? And how do they compare?

Xamarin looks promising, code reuse is a big plus, but i'm wondering if it's used in larger corporations/apps?
Yeah, I'd second that. The front of the shops are always filed with the tacky flashy junk, but there was still quite a robust selection of components and smart staff in there.
But also that everything they sell can be bought from Aliexpress at a fraction of the price.
Yes, I was being a bit harsh there - the components sections were good - the reason why I did occasionally visit!

A bus takes as much lane space as 2-3 cars. You almost never see a bus in NY (even during off hours) with fewer than 5 people in it, and during rush hour it's not uncommon to see them packed to the gills. Sometimes people are packed in so tight you have to fight to move the 6 feet to the door.

BTW, 20 is a very low estimate. A typical bus here has about 30 seats, holds 40 comfortably, and 75-80 when crowded.

https://en.wikipedia.org/wiki/Rosa_rubiginosa points out that the rose hip plant is an "environmental weed" in NZ, and that "Growth from seed is aided by the reduction in competing pasture by rabbits." It links to http://www.massey.ac.nz/massey/learning/colleges/college-of-... which says:

> Pasture competition prevents new plants from establishing, though established plants are very competitive. Rabbit infestations have helped the spread of sweet brier by reducing pasture vigour. Cattle, possums and birds spread the seed by eating the fruits ("rose hips") produced around the seeds.
> I don't consider "Android" to be an OS.

Then you're correct by your definition, but not by most people's definition.
> It is theoretically possible that the black hole is still performing fusion, and emitting light and heat, like a regular star.

I don't think that's a useful picture. It's closer to the truth to say that from the outside perspective, all the information and energy sits on the border and there is not even an inside to speak about. In other words, it's the edge of the universe and what's past the event horizon is another universe. Not like a star at all.

Strains of Nietzsche's thought seems to underlie the political extremes of both left and right, particularly right now:

- The death of Christian tradition and morality, which (despite its de facto shortcomings) provided a common moral framework and language that let people talk to one another

- The loss of meaning and one possible responsible response, which is to generate your own meaning independent of the morality of others. Note that this thinking helps justify both revolutionaries and reactionaries, since you are heroic for rejecting societal norms.

Jordan Peterson discusses Nietzsche in many of his videos, e.g. https://www.youtube.com/watch?v=KgBuOQL1VYY
That would indeed be a silly claim as RHDV1 K5 is itself a strain - a mutation - of RHDV1. It was found in a rabbit farm in South Korea.

The claim is that it is all but impossible for this strain to mutate to infect another species. Not that it's impossible for the strain to mutate.

RHDV1 is already endemic in Europe and elsewhere. There are plenty of opportunities for that virus to mutate.

None of the mutations affect anything other than the European rabbit.
Is Calvinism the idea that Calvins should govern the flow of all resources?

Yes, I loved the catalogues of that era too, especially since they commissioned SF art for the covers: http://70sscifiart.tumblr.com/post/166105106512/maplin-catal...

In the modern era their shops were useful for the "need a Usb cable/external disk/whatever today and will pay the premium for getting it immediately". But I'm not too surprised that that kind of thing wasn't sufficient to keep them going.
At least in NYC the congestion has many causes:

- the continued growth of the population

- active measures taken to eliminate lanes and slow traffic (the avg speed is down to 6mph)

- the continued decline of the transit systems (the subway system is dirty, full of homeless people and unreliable... on time arrival has declined significantly)

- also its not just the subway, nj transit and lirr both have major reliability and cost problems. I take a train from nj every day and I consider myself lucky if my train isn't cancelled once every other week, leading to 3 hour commutes. I dread the next major tunnel failure leading to a week or more of no transit options

- the inability to add more capacity to aging infrastructure. It took over 50 years to add the 2nd ave subway and it still isn't finished. almost everything is packed at rush hour leading to a deeply unpleasant commute

- taxi service was artificially limited which led to the proliferation of ride sharing services. They're all subsidized by the companies though, so its hard to know if they're actually viable businesses

- recently enforcement has been more strict in midtown. You will see traffic police at most intersections, and drivers are ticketed for blocking lanes. The blatant disregard for laws is a major issue. Cars and cyclists regularly run red lights and people walk into traffic ignoring crossing signals, which leads to cars slamming on their breaks, and then because traffic stops, all the other people on the sidewalk decide to cross, and the whole thing grinds to a halt.
Don't know anything about RNA, but I wonder if some kind of small virus could be used to test the micro RNA transport hypothesis. Googling "micro RNA virus", first link is https://www.ncbi.nlm.nih.gov/pubmed/21431678 . The paper seems promising, since 2004, more than 200 microRNAs (miRNAs) have been discovered in double-stranded DNA viruses, mainly herpesviruses and polyomaviruses.This chapter aims to summarize our current knowledge of viral miRNAs, their targets and function, and the challenges lying ahead to decipher their role in viral biology.

Using microRNA virus to test the sperm transport mechanism seems to be a good idea.
Glooging for "microRNA virus sperm transport" suggest the link: Intercellular Transport of MicroRNAs (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3580056/), This review brings into focus what is currently known and outstanding in a novel field of study with applicability to cardiovascular disease.

So, perhaps sperm transport of microRNA could be tested using some RNAvirus to produce cardiovascular desease.
There's no mention of IVF/in-vitro-fertilization techniques and whether male micro-RNA can survive that process. There apparently are side effects of IVF and I wonder whether they could be due to degradation of male RNA transport.
You seem to have been down-voted. Wasn't me.

Just like email spam, I assume there's enough benefit to be worth the cost, which is far less than it used to be now that, much like the transition from physical mail to email, a computer can do the calling for very little cost or effort.

I used to get a a few random spam calls from people a week, and still do from time to time. They're generally trying to sell me something; trying to ask for my vote; trying to convince me that I'm in trouble for one thing or another and I should give them some personal information or money to get out of it.

As for being called by bots, if I answer and I don't hear a human voice within a second or two, then I assume a computer just dialed me. It might play me a recording; It might connect me with a human. Regardless, it was a bot that called me to begin with, and I've no interest in speaking with or waiting for the unsolicited demands of computer programs.

I used to be able to keep a list of numbers to block with whatever dialer app I was using, but it's gotten incredibly easy for these spammers to spoof numbers. The big trend in the past couple months seems to be to use numbers that have the first six or seven numbers of my full ten-digit phone number. So if my number was 444-555-6666, I'll get random calls throughout the day from 444-555-6777. It's obvious when I see the number - especially since my number is from a city I haven't lived in since 2012 - but harder to block via standard phone apps.

This is why the white-listing of a "Do Not Disturb" mode better suits me.

As for why I get so many spam calls, it's hard to say. I've had this number for almost 20 years. I'm sure it's been sold and resold for pennies hundreds of times. I'm sure it's also on plenty of database dumps from various hacks as well. No matter, switching numbers seems to be more hassle than it's worth. I assume whatever new number I get would be just as bad.

What I _really_ want is for phone numbers to become obsolete. Just a random UUID that means "Call / Text / Message enobrev" in someone else's device, where I can maintain a whitelist of who can connect to my devices to talk / chat / etc.
Holy shit what.

What is this? Could you tell me more? I spend inordinate amounts of time in front of the computer and never heard of this, and a quick search doesn't reveal anything obvious.
I think most people are unaware of that, and also when you buy from Ali you're invariably paying steep customs fees (tax + holding charges).

They were ridiculously expensive for stuff like cables, they were reasonable on common IT kit (wifi extenders, etc.) and sometimes ok on PC components, and often they had some really great offers.

I think a lot of people don't realise quite how broad their catalogue was - they sold disco gear, speaker cables by the metre, all your discrete components and gizmos, plus a bunch of smart home stuff, telephony, etc. And as others said, they had decent staff who could often give good advice.

It's very sad that they've not been able to sustain a place on the High St.
Not surprising really. I've been into a few of their shops and they always reminded me of the last days of Tandy / Radio Shack: cheap stuff and unhelpful staff. I'm sad for the people who will probably lose their jobs though. Very hard to compete with online suppliers in that space.

My local Maplin is/was the only physical shop in reasonable travelling distance for emergency purchases of things like perfboard or solder. But when they stopped selling even a basic selection of components I switched to ebay and haven't been back there.
I found this gif particularly amazing because it did. And the others a little underwhelming.

Tragedy of commons perfectly applied to communism and socialism where shared resources are overused. Free market is quite opposite to tragedy of commons since it's based on private property, not on shared resources.
Optimizely is now focusing on the enterprise segment, which requires a different culture and skillset than you'd need when selling to smaller businesses. Doing both at the same time, for most products, will almost always require two separate cultures, which is difficult to maintain (unless you're a giant corporation with different departments). An exception to this rule may be Slack, where price points grow linearly with company size.

In website testing, specifically A/B testing, the enterprise segment is likely more valueable as smaller customers tend to exhibit vastly higher churn rates. Also, a 1% increase in conversions will translate to millions in incremental revenue for established companies, making it much easier to justify higher price points.

What's interesting here is:

- this is the first confirmation I've received from a company stating outright that they're not going to be GDPR compliant and you should stop using them if you need to be.

- they're explicitly saying it's too much effort to store data in a compliant manner and ensure their processors are complaint. this possibly raises some interesting questions about what exactly they're doing with the data they have today.

- this GDPR thing is like async code, once it gets into a system it has long tentacles. I don't think this company fully realises just how many companies need to be GDPR compliant to continue doing business online. if you're in the SAAS business, it's very likely you're dealing with EU customers - or at the very least a customer that deals with EU customers, or an customer of a customer that deals with EU customers. You get the point - this tentacle keeps reaching down. You may think you're not excluding many of your own customers by not being compliant because THEY aren't EU-based, but it's their customers/controllers etc that require them to be compliant and thus you.

This tentacle is all encompassing.

There's an incredibly clear correlation between firearm deaths and gun ownership: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3828709/

And if you don't think high muzzle speed and high capacity magazines increase effectiveness (read: ability to kill more school children faster) then you'd better let our military know.

It really takes willful ignorance to pretend that having higher numbers of more effective killing tools has nothing to do with deaths.

maybe this indicates that it's not the firearms themselves that are the problem

And again. The incredibly simplistic way of thinking. The problem? There are many problems! Properly addressing this would take many solutions. Mental health problems are fundamental to our species and may never be completely be eradicated, but we can do better.
