My retired uncle lives in Kreuzberg with his family since he was a teen. They quite like it and just never moved out.

It has a lot to do with what you can expect from your neighborhood. A nightclub opening up right next door in a silent neighborhood is a recipe for a disaster, but it is similar with people moving into regions with a famous nightlife expecting a normal place to live. I for example dont have much sympathy for people moving in next to Frankfurt central station and then start to complain about the drunks, punks, junkies and hookers. Its like moving in next to train tracks and complaining about the sound of the trains.

I'm not afraid of specialized tools. For example I've used RabbitMQ which I believe is written in Erlang.

We run it in Kubernetes in both our CI environment and locally so we can use the same configuration for both. It runs a dozen microservices and saves us a lot of devops time.

In our CI environment it's nice for a developer to roll out a new copy of the services from a different branch for testing, and because of the autoscaler nodes are dynamically provisioned when needed, and then removed when the test environment is destroyed. That's pretty nice functionality you get basically out of the box. On EKS anyway. There are some occasional rough edges, but I think the decision to use k8s for this makes sense...

At some point we'll migrate prod too.

Kubernetes has a lineage as well... Based on the Borg project at Google.

I guess I'm not seeing why these things are being compared. Aren't they solving different problems?
MIME has the format=flowed option that would handle auto-wrapping text at the display width. But it requires leaving a trailing whitespace character at the end of each line that you don't want to hard-wrap (which wouldn't work well with most code linters without changing their configuration).

I don't know, I agree that all the speculation about speculation sounds crazy to me -- the rent usually adds up to the cost of buying (via the interest rate, I mean) so not taking it is an "order 1" loss.

One possible reason is rent control, can anyone comment?

If what you risk is getting stuck for 30 years with a tenant paying last year's rent (and you think it will rise) then that could be serious money, of the sort which might make a rational landlord leave it empty.

This is a straw man argument. The employees prefer not to develop products that kill people, that's very different than opposing the concept of a military.
I’m pleased Nadella doesn’t shirk from this as Google did. Of course in an ideal world we wouldn’t need these technologies and abilities to sew destruction, unfortunately rivals and foes aren’t vacillating about such quandaries.

I’m pleased he sees beyond a small minority of active dissenters.

Unlikely because you aren't going to share personal, identifiable information with this service; you would just send the primary key of the user in your database (usually an integer, guid, etc, as long as you aren't using some string that includes personal information like email or possibly username where they user picks their own name).

You can share all the information you want with other entities under GDPR as long as the information you are sending as long as you can't uniquely identify someone from that data _without_ additional information.
Who is this for? Is the goal to enable people who don't know what they're doing at all to make applications?

Maybe at a glance that is a laudable goal, but surely there is a point where, if you need so much handholding, you should consider either sitting down and learning what you need or making someone else is build it for you.

Newbies? I guess that is possible, but I personally think that actually learning to use your tools and the libraries that are available should be the goal. Handing the control of everything to some 3rd party component is eventually going to leave the beginner with issues they have no way of solving because they've never had to learn anything.

I've got a question about AR goggles. If someone knows, please tell me:

My main use case would be to free me from sitting by a screen. I want to be able to access mainly Slack, a browser and some IDEs so I can casually do some code review or chat to team members as I do some chores around the house. I'll need notifications as well. But mainly I want to be able to read stuff while being mobile.

Are there AR goggles that will let me do that?
Why neutrons and protons are modified inside nuclei
Commercial property often has really long leases, like 10-20 years. So one reason it may sit empty is that an investor thinks a slump will be short & doesn't want to be tied to a low-rent tenant. (Or doesn't want to break up a large space for small tenants, to wait for a large one... or because they are thinking of knocking it down & building housing, etc.)

I'm dubious that people in real-estate can't understand local prices, I mean within London there are vast differences by street-by-street. I'm also dubious that empty properties & claims about what they could rent for will fool many people.

It's not a false equivalance. Yes, China is worse on human rights and they are using technology to enable tyranny. But the US is bugging all these devices and they don't like to be called out on it! I never imagined that in 2019 we would be having this conversation about rogue intelligence agencies that have been so successful in bugging all our tech. The cyberpunks of the '80s lost the argument. We can regain our footing, however. We can demand spy-free, hard-crypto electronics.
That kind of evolution takes a while.

I block all third-party requests with ublock and enable them one at a time (targeted, by looking at what they are manually) to get websites working again (when I really want to). It is generally insane how many external requests are 'needed' to display very basic websites like blogs or general information websites of companies.

There is lots of information on optimizing images and whenever I speak to designers they always say "don't worry, we optimize the images", which is great of course, but they completely overlook all the JS. Many websites don't only load more JS in terms of raw file size, but the parsing of all this JS then, again, takes more time than loading all of CSS and images, combined. And for what? Usually some annoying pop-ups, image sliders or some chat-box. In fact, those chat-boxes themselves load complete web pages in the iframe they are created in. I also see websites loading multiple versions of jQuery.

Anyway, 117 external requests for anything, let alone a blog, is insane.
Not CPUwise. But they have increased the number of CPUs available and that's where python has problems because of the GIL. Fortunately the multiprocessing library seems like a good workaround to the GIL issue.
+1 for Hetzner, it's amazing -- I'm particularly fond of their dedicated server offerings.

One of the things about Kubernetes I like most is the likelihood that it reduces the barrier to entry for "PaaS land" (and resultingly "cloud land") for providers like Hetzner (see OVH's recently announced k8s offering[0]).

Once these "baremetal" providers get in the managed (by k8s) game, I'm certain companies will start to spring up and offer/chip away at cloud provider offerings like S3/RDS/etc -- they'll just connect to your k8s infrastructure, and bring their kubernetes-compatible know-how. This is going to cause prices to plummet, as it will make the tiers of value added services more distinct -- i.e. "a platform to run things" on vs. "really good managed databases".

I'd be fine with no backdoors for anyone as a strict policy. The whole "24" argument that government agents won't be able to head off a terror attack in time is so much bullshit when what they are really doing is spying on all of us and then using parallel construction to build legal cases against those they wish to attack. It's extremely autocratic, very one-down, freedom-less system we have here in the states right now. It's disgusting, quite frankly. Public ignorance of technology is what has allowed it.

Love this thread--people need to start understanding that the West isn't better than China on spying, it's just a softer tyranny (for now) that we live under. It's still tyranny.

By the way, this is why I own guns and support the 2nd Amendment--it will be necessary as the last stand against what we all know is coming.

> With a bit of effort anyone can find products on Amazon that sell well (there's services that will do this) and then try to compete with those products. Amazon undoubtedly has more insights than those services provide, but that's

The fact that they can make sure it makes is prominent in any search result in the category, even for a competing product, is what makes it, combined with the fact that it's the one thing on Amazon you can be 100% sure isn't counterfeit, size no one else can sell it so there is no risk of commingling. It's nice that Amazon has found a way to trade on the unreliability of their own marketplace, and to leverage dominant market power in online into marketshare in any particular product market they choose.

Great for Amazon, that is; not so sure it's good for anyone else.

I thought it was normal practice not to export environment variables so they are only available to a particular process.

I think env variables are bad for passing info between processes, but are good for loading different configurations into processes consistently.

I always load my env from some config file, but I like that the apps don’t care how config gets stored. I like the abstraction of the process not needing to be aware of how config is managed.

And where the usefulness of K:V store is beaten by SQL is the point you would want to run a "JOIN" or "GROUP" on the data, for example if you wanted to count the number of keys containing a certain data point, correct?

Ask HN: How to Breathe in a Polluted City?
I'm asking this in HN because this is the only place I can expect to not get kneejerk answers, I honestly know of no better place to ask this.

So I live in a "developing" country and have to commute by foot for about 10 minutes after getting off the subway to reach my workplace. This road is quite busy with lots of Soviet-era and other kinds of high-pollution vehicles that just keep spewing big clouds of whatever and causing me headaches and sometimes even chest pain.

Some websites suggest N95 masks but they all seem like cheap marketing articles more than anything. So I wanted to ask, are N95 masks effective at all against car pollution? If not, are there any other alternatives that don't involve carrying around an oxygen tank?

Thanks.
Air to water heat pumps are also used in harser climates. If you're interested here is an example datasheet of an air to water heat pump (2018) (using Celsius here):

PUHZ-SHW112YAA
Guaranteed operating range (outdoor):
Heating: -28 to +21
Domestic hot water: -28 to +35

On page 108 you can find the actual co-efficient of performance (COP) for different outside temperatures and inside water heating temperatures.
As an example: at -10 and an water temperature for heating at 25 you still get a COP of 3+ (which are the average low temperatures in Maine). That means that 100% electricity moves 300% of heat into your house.
Cardinality is the name given as a measure of the size of a set. The cardinality of the rationals is the same as the integers. The cardinality of the reals is larger than that of the integers.

There is an arithmetic of cardinal numbers and it is well understood if you accept the axiom of choice. For instance, using your notation, N*N = N and N^2 = N. You can read more here

Many of these commentors have it backwards. I know this because I’m actively working on a similar project at AWS. It isn’t that Amazon wants your data to help it make decisions, so it builds a clever product to get all your data. On the contrary, Amazon has so much damned data and years of experience turning that into a valuable asset, that it has started experimenting with ways to sell that value to other customers. The idea that it wants some mom and pops retail data is just silly. Our biggest problems are scaling the internal services we built 5 years ago to handle all the growth.

SageMaker was a ground floor service and you should expect to see many more services built atop it.

I believe if you think of Redis as a data structure server, then there are lots of applications you can build out that have simple commands like set and get for both lists and hashmaps that are slightly different ways of thinking about saving and retrieving your data. The concept of a set is very powerful and easier to implement I believe than using SQL.

You missed the point.

A day will come when CPU speeds and RAM sizes will stop increasing. When that day comes you don't be able to ignore performance, because a lack of performance will mean actual, real-world dollar costs for the client, and so performance will be the #1 requirement of the client.
