For what it's worth, the definition of 5G isn't really settled yet. To some people it means a high rate multi-antenna system in the existing radio bands (in the approximate frequency range 900MHz to 2GHz). To others it means a wide-band system at a centre frequency of approximately 60GHz.

The 60GHz band was specifically chosen for short range wide-band data transmissions because it is close to the absorption peak for oxygen. This means it doesn't propagate far in air, making it a poor choice for much other than short range communications, where it's an asset if neighbouring cells don't interfere with each other. Short range in this case means a cell in every room of a house, as typical propagation distance is about 10 metres.

Given that the 60GHz band is specifically absorbed by oxygen, and the body contains oxygen, it strikes me that it's worth specifically testing the biological effects of this band, separately to existing cell phone bands.

Note that the article under consideration here tests at 900MHz and 1900MHz.
This is certainly true. Of course if they can't report science correctly what chance do they have on any other subject that I don't know about :)
Tutorials for setting up a personal email server are fine for educational purposes -- or -- if you're primarily using it to receive emails.

On the other hand, if you absolutely depend on the ability to send emails such that your recipients reliably get them, hosting your own email server is extremely tricky. One could carefully go through the checklist of SPF, DKIM, ip blacklists, etc and emails will still be rejected by MS Hotmail, GMail, Yahoo, etc. Those giants are "black boxes" when it comes to their heuristics for rejecting incoming mail as spam. E.g. your hosted email server does nothing wrong but some other bad actor on your ip block sends spam which then makes MS/Google block you because of "guilty by association". Trying to debug your "sender reputation" is not easy.

In the 1990s, I hosted my own home email server over ISDN lines. These days, I have a million other things I'd rather do than babysit a personal email server with software updates, SpamAssassin lists, etc. I get the whole decentralized ethos but it's just not worth the effort for email servers.
I've already put in a lot of hours to that depressing topic, mostly a couple of decades ago. That Scott Noble stuff recently was more than enough.

I do seem to remember Saddam got into power with U.S. help, then they sold him about 10 kinds of chemical weapons. Have heard a bit about Pol Pot. Not sure why you just mention those 2 countries.

If I want to what?... Uh. So I guess you know all about the U.S-funded fanning of extreme Muslim flames in the area. With the purpose of starting a war, wasn't it? But sure, 'tangential', no abuse of human rights there.

Well, maybe you're an expert - what do you believe is the total number killed by the U.S.? Less than "millions"?

I notice you did the straw man thing that you did here also with user982's LeMay comment - finishing your post with something the other person didn't say and saying it's not true.

Also I'm getting that you think the U.S. isn't evil but other countries are 'truly evil'. Sounds familiar.

Well, thanks. Sorry, I wish I had the interest/energy/time etc for a long exchange about this, but I don't.

$100,000 x 1,000,000,000 people = $1 x 10^14 (assuming most people in the US+Europe are vaccinated).

I assume it's hyperbole and you don't mean to say that the studies required by the FDA are comparable to the GDP of the US? Are you sure a price of $100 would not cover it?

Any time you damage any part of your body, that tissue has to repair itself. There is always a chance (albeit small) of things not repairing themselves correctly and the DNA getting corrupted. Every time the same tissue has to repair itself, the odds of DNA corruption occurring increase. This is why cancer tends to manifest in areas of the body which are chronically damaged and repaired (such as an alcoholic's liver, or the esophagus of someone who has chronic heartburn, or the lungs of someone who smokes).

As such, it stands to reason that any type of burn (causing tissue damage) could ultimately lead to cancer.

Or at least that's my current understanding.
Less experience to see through the bullshit from companies too and they do not yet really believe they are just a number in the cost center column in HR and that the company they are working with will not waste 1 second before getting rid of you.
Cool article. I personally use Virtualmin for this, it's very easy to set up, you can manage hosting and mail accounts for a bunch of different domains, easily do backups via S3, easy to set up SPF and DKIM, has a good web admin interface, easy to set up automatic updates, etc.

By the way, here's the obligatory HN-style critic of the format, not the content: the blog template in this is a little annoying, it fiddles with scrolling by making it really slow on Safari on Mac, and Reader mode doesn't work.
You're still relying on another party when you do a Google search, hell if you want to get crazy about it, you are relying that you were correctly taught literacy and that when you read a word, the meaning it has for you is the same meaning the author attributed to that word. It's not guaranteed
What kind of colossal idiot would block an email because it comes from a certain IP-block IF SPF and DKIM has been properly setup?

Is this an urban legend that just keeps getting repeated?
Traffic at the turn of the century in Seattle was shit, I remember how great it was to be able to check the traffic on a Treo before we'd slog it out on I-5! That was huge innovation, to know whether Aurora or I-5 was truly fucked up.

Now, I have significantly better bus service with dedicated lanes into downtown, and for last mile hops it is easy to grab a bike and go.

WRT Transparency, lets pass through all costs to the end user and let people decide! Do you want to pay $1 to cross the Ballard Bridge each way in a car? How about $4.50 for any mass transit mode? Or $1 for a bike for an hour?

Hiding the true cost of infrastructure, whether its through free parking, subsidized roads, or reduced fares is wrong, people should know what it costs and be able to choose freely!
“Join Medium to read this.” Guess we’ll see if that pays off.

Obviously the US has a very low overall population density, being for the most part a wasteland devoid of human life.

China, on the other hand, does not seem remarkable: higher than the European average, lower than Germany, way lower than India.

http://m.wolframalpha.com/input/?i=Population+density+of+Chi...

Of course, it's a pointless metric and it fails to capture that China, too, is for the most part a wasteland devoid of human life and it still has about five times the USA's average density.
There is substantial scientific evidence showing age-related cognitive decline begins relatively early in adulthood. The science is not controversial.

http://examinedexistence.com//wp-content/uploads/2013/12/cry...

This is a simplified view but communicates the idea.

Some might say crystallized intelligence is under-valued in tech. That might be true. But then we should discuss that, not through the lens of social justice against age discrimination.
The internet will go crazy over China now, mostly of which will be:

1. Abuse human rights.

2. A dictatorship.

3. South China sea.

But the internet will happily use "Made in China" shamelessly. Hypocrisy at its best.

> Forcing local governments to charge below market rates is little more than corporate welfare for the telecom industry.

I am sorry I spoke without understanding the entire situation but I have sincerely zero sympathy for local governments in this case.

I concede I'm wrong though. The problem I see now is here is the fact that an incumbent will "rent" all the good spots for free, claim it is under development, or somehow basically starve competition.

I hadn't thought of that. I was trying to avoid the situation like when the first 3G iPhone came out and Cingular was saying things like they can't find anywhere to put network equipment in San Francisco.

Basically, my thought was this pits two categories of rent seekers against each other and was hoping that we could exert pricing controls on wireless carriers using this but I was clearly too optimistic.
Correct me if I'm wrong, but I think that not being allowed to count means that you should treat odds as if the cards were extracted from an infinite stack with a given statistical distribution of cards. Reshuffling when you only extracted a low number of cards from a finite stack basically approximates the infinite stack, so, the odds should be exactly as expected.

It is not cost (I was referring to the cost of curing hepC), but that it is impossible to get a vaccine past the FDA for the common cold.

It would actually be easier to bribe congress to shut down the FDA than perform the studies required to get a cold vaccine approved - at the very least the bribery approach has a chance of success.
It doesn't make sense, but often people and businesses are concerned about it being awkward for someone to report to a manager younger than them. Rather than educate and reassure they prefer to avoid this altogether by not hiring older people. For many, there is also a perception that for someone to not have climbed the corporate ladder by the time they reach their 40s is a signal of failure. With younger workers this signal doesn't exist.
MS actually have a service where you can register IP’s you own and it gives you a digest of what people have marked as spam that originated from said IP’s.
Their headers also tell you a lot, excepting the content filter one which is a bit of a black box and I don’t believe actually is purely a content filter based on messing with it.

Maybe I'm being overly optimistic, but I think a lot of the discrimination is specifically anti-Boomer or anti-people-who-didn't-grow-up-with-Internet, not specific to age. If true, then 40 will be the 30 of 10 years ago.
I led the comment with "I really don't think it's that clear cut" - intending to indicate I was about to express an opinion.

I have a friend in the NYPD, who did not turn his back on the mayor in that incident.

This problem needs to be solved from the top down. Police need to be constantly reminded that their job is more than just being enforcers.
I think that we cannot full understand the implications of that in our present/near future. The use of tecnhology will make the difference. There is a small book in amazon called something like Alpha Go Zero - 10 prophecies for the world. Interesting point of view of the use of it.
> But how does that close over other locals?

It does not, it works like a C++ destructor, the context management code is static, and anything it needs is provided as a parameter.

While "ad-hoc" context managers are possible (and quite trivial in fact):

1. I don't remember ever wanting one

2. they would not be convenient owing to Python's limited lambdas so

3. you'd probably implement them using a ~decorator on a nested function instead which

4. may look quite odd to most Python developers
“Yescarta and Kymriah do work similarly, though. Each involves removing a patient's T-cells and shipping them to a facility where they're engineered to spot and bind to CD19, a protein commonly expressed by B-cell cancers. Once the companies have finished altering the T-cells, they're infused back into the patient.”

This seems to be quite an outlier in a discussion on general vaccine economics.
Maybe experience can be more valuable than raw cognitive ability?

I don't have time to reply at length on a touchscreen but this topic comes up every time someone links "how to self-host email". Saying it's extremely tricky is exaggerating. Everyone agrees it takes more work than it does to create a gmail account, but it's not that hard either.

I don't think we should dissuade people from doing it, especially if the fact that more people doing it means that it'll be easier next time because it'll be slightly more common. Many of us are in tech and the field is a small subset of the population. Even if it's a small amount of servers setup by us, that could make a noticeable on those working at bigcorps who write the hostile receivers.
On behalf of all old people: Fuck that, and fuck the idea that cognitive performance alone should determine whether someone in our industry can eat.

Because as much as we love to tout that every programmer is living with a house and a mortgage and a happy family, I happen to know for a fact that some are struggling to eat.

Eh. Not exactly an objective viewpoint, I know. But to maybe drain away some of the energy I just threw into that: Being old is our shared destination. It'll happen to you too. It'll happen to me. How is this a productive outlook?

I've known some amazingly productive old people. I learned from one of the best in the gamedev industry. He was my mentor, and basically a mini carmack. When I hear statements like this, I cannot fathom how people believe this myth that old people are inherently less able to kick your ass at programming.

I really hesitate to bring this up, but there's this dopey argument that HN trolls love to bring up, where they point to a certain area of science and say "Look! Black people are inherently dumber. The science says so." Yet the one black man that I was fortunate enough to work with in our industry -- one, out of six companies, there was only one -- was the most effective, cool coworker I was fortunate enough to know.

It's incredibly easy to point to some science and say "Oh, I'm objective." But I invite you to re-read http://www.paulgraham.com/bias.html carefully, and realize that if what you say is true, then our industry is populated with stellar outliers. That's the definition of bias, right? They have to be stellar to overcome it.

So why would you want argue that the stellar people that managed to get through the gauntlet of discrimination should be looked down upon?
No, it's real. I gave it up a year ago, after hosting my own mail since forever. Exactly as stated: Hotmail (or whatever MS mail is called these days), GMail etc. are the main culprits. So yes, 'colossal' is the word.
“Indeed found that 17% of survey respondents said the average employee age at their company is between 20 and 30 years old, while 29% of survey respondents said the average employee age is between 31 and 35. An additional 27% of respondents said the average age at their company was 36-40 years old.

That leaves just 26% of the workplace roles for staffers over 40, Indeed found.”

Innumeracy sucks at any age.
Slightly related: I was just looking to buy Microsoft Office 2016 for Mac for my mother. She's American, but I'm currently in Bulgaria. The Microsoft web store says it's $149 but when I add it to my cart it becomes 289 Bulgarian Leva, which is about $174 (and the whole page annoyingly switches to the Bulgarian language). Then I look on Amazon.com and see you can get it for $129. God I hate digital software pricing.

I feel this might change when more of the current young generation of engineers are getting older since there just weren't as many tech workers 20 years ago, so it's still relatively rare to see 50 year old developers. Besides there are many places outside of Silicon Valley or the US were experienced engineers are very welcome.
I was surprised when I first saw the word "tensor" being thrown around by computer scientists to apparently mean just multi-dimensional array. But then I thought, well, "vector" is very widely used - including by mathematicians - to mean simply an nx1 or 1xn array, rather than an object which transforms a certain way under coordinate tranformations. So in the same way, I suppose we really might as well use "tensor" to mean "just" a multi-dimensional array of numbers, in contexts where coordinate transformations aren't important. Mathematical physics can continue to use the other definition where necessary, just as it does for vectors.
Nope, Single Occupancy Assholes, who make up sub-30% of Seattle Commuters and create nearly all the traffic are very entitled. They expect the rest of us taxpayers to fully subsidize the roads, provide free parking at most public buildings, parks and on most streets, and then have the gall to complain about minor point of use fees!

Lets cut the bullshit and bill drivers directly for every mile of wear they put on the road, and for the massive hidden (and unbilled) cost of car storage on public streets and at public facilities. Given a fully transparent market, single occupancy commuting would die a quick death!

Hell, even a minor $1 entrance fee into/out of downtown would shave SOV traffic down 15% to 20%, despite not passing through much of the cost.
I'm sure they collect it for a while, but that doesn't mean they can declare it as their own for tax purposes.
Startups and such typically don’t want young people because their smarter, it’s because their more gullible career wise. Sure some people get a bit stale with age but some also get far far smarter and their experience can be very valuable.

“Hey guys we have no business plan or customers, but please pull a few more all nighters to finish this bit of code.”

22 year old living with 5 roommates is like “yes sure, whatever you say” while 40 year old with lots of experience is like “you don’t know what the F you’re doing... I’m outta here.”

That’s why.

It reminds me of a quote. The British number theorist G.H. Hardy, in A Mathematician's Apology, one of the most widely read books about the nature and practice of mathematics, famously wrote: "No mathematician should ever allow himself to forget that mathematics, more than any other art or science, is a young man's game."

Basically, the claim is that people over the age of thirty being productive in math is an anomaly. However, I've never used any advanced mathematical concepts as a programmer so I doubt my quote has any validity here. I imagine things are different in data science but I only concede because I have no idea what data scientists do. It just feels like magic.

I'm not sure what straw man you're referring to, but I'll address yours: I have never called the US perfect, and it has done many evil things. The difference is that you can talk about them without disappearing.

You and User982 are criticizing the easy target that is the US and in the process deflecting from the vast oppressive machine that is China. This is a post about China, and US atrocities don't excuse the greater Chinese ones. No straw man involved.

Why are you assuming most in Europe and the US would be vaccinated? If it's not life-threatening, most people won't bother. Most people don't even bother to get the flu vaccine each year. I got a Hep B vaccination when I went to South America, but I never got around to going back for the booster shot. I'm a firm believer in vaccines, and my children will certainly get all of theirs on schedule, but I'm unlikely to get a cold vaccine for myself - and suspicion that the vaccine isn't really good for me in the long run would be part of my reason, beyond laziness.

I can confirm this 100%. I've had to work with some really really bad Clojure software that is unbelievably hard to maintain. This is not a fault of the language, but just more proof that no language is a magic bullet.

Try to understand why things are done the way they are and what is actually happening instead of just following the tutorial systematically. If you have some knowledge gap, say in basic HTTP or data modeling concepts, make sure you read about those as well. This will strengthen your understanding of the framework.
Also, if this is your first time with Python, I highly recommend learning Python before learning the framework. This applies to any language out there.
Yep I did the same. I ran my own email server off the same IP address for 15 years with zero problems, but I had to give up recently because email is not something that you can do on you own anymore. You now have to pay some somebody to vouch for you or else MS will send your emails to spam or even worse just randomly delete them.
