dennisdamenaceon Internet access is quietly changing Seattle’s tent cities

There was a post on HN some time ago by a homeless woman. One thing she said would a lot is wireless access. She said a great deal of time and energy would be spent moving from the camp to internet availability.

dennisdamenaceon 100 Years Later, the Madness of Daylight Saving Time Endures

How much expense goes into software which needs to support daylight savings? How many bugs have occurred because of it?

Personally I deal with this problem a lot. It is a pain and expensive. Of course this is a problem because the time data my software ingests often doesn’t include the offset or zone. So I have to work around it. All for subtracting then add one hour for the year.

dennisdamenaceon Tell HN: Slack decides to close down IRC and XMPP gateways

Why is it a bad idea?

And I doubt _any_ business has centralized their communications with Slack. I’m sure they are still using phones, and email and face to face communication.

dennisdamenaceon Do we need to move away from Elm?

You are wrong. Anyone can publish a package for Elm - without approval.

What you can’t publish is a package with JavaScript in it. And, if you understand Elm, this makes sense.

Elm has no runtime errors - which means any JS has to be perfectly designed. Elm is not to be bound to just a JavaScript platform. Elm has ports for interior.

As for bug fixes - there appear to be some cases where there are bugs, but I have never come across any. The langauge just works.

The slow pace of releases is a business adavatage - we don’t need to be upgrading every N months.

The last upgrade had tools to automate almost the entire process.

Anyway. Would you wager that Elm will fail? I will put up $1000 to your $9000.

dennisdamenaceon Do we need to move away from Elm?

The upgrade from Elm 0.17 to 0.18 was almost 100% automated. I thought it was going to be painful - but, thanks to the type system, wasn’t. Nothing like Angular.

dennisdamenaceon Do we need to move away from Elm?

I’ve been using Elm since 0.16. Development is slow and thoughtful. Perhaps 0.19 will be a disaster, but I doubt it.

In the meantime 0.18 has been a very productive language.

One thing to understand is Evan wants Elm to be a language and not bound to JavaScript. This is the sound motivation behind blocking native packages.

We have used tmux session sharing in the past over Vagrant share - none of us are on the same network. But I can’t say it is seemless. Tmate.io looks like a great solution.

Yes it is. Thank you

If I understand - with the piping you could share a read only terminal over the net?

My team has been using Atom and Teletype to pair - but no lightweight method to share the test console. Could this be it?

I often learn a lot at the check out lines here in Oregon. People chat, exchange information. Often banal, sometimes valuable. Always nice.

dennisdamenaceon More than 94% of net new electricity capacity in the USA from renewables in 2017

Keep in mind capacity does not equal generation.

A solar facility with 1MW of capacity will generate 1MW at it it’s peak moment, maybe, on a good day. Given the lat, weather and season, maybe you will get 8MW hours total for the day. Whereas a 1MW gas plant could produce 24MW hours for the day.

In other words you could have 100MW of renewable capacity and have 0 generation if it is too cold, dark or calm.

dennisdamenaceon Power Prices Go Negative in Germany

Are you looking at domestic generation or imports too?

dennisdamenaceon Power Prices Go Negative in Germany

The article doesn’t mention this but I will guess this is the real time market, or spot market. In off peak hours and especially at such high prices, you are taking about very little actual energy. Most of it would have been purchased in the day ahead market.

This happens all the time in US markets - especially where there is wind.

It is done as a price signal to producers to either ramp down or consumers to buy a bit more. The ideal winner here is pump storage. But they may have already schedule themselves in the day ahead market and have no extra storage.

The market is far more complicated than the article let’s on.

dennisdamenaceon Power Prices Go Negative in Germany

The article also fails to distinguish whether this was the day ahead market or real time market.

In various regions in the US prices go negative often. Nothin usual. Good time if you have storage.

But most of the generation, 89%, is in the day ahead market which rarely goes negative.

The article also doesn’t bother to mention that Germany burns more coal than the US as a percentage of fuel mix.

Lousy article misinforming it’s readers.
