Xarodonon Show HN: A Database Written in Golang

Yes it's a CLI REPL, you build and run the binary using the instructions in the README and then create/insert/select from it by typing those commands into the CLI.

Currently there's no way to connect to it like you would a normal SQL db, but you could embed it like you would sqlite.

Xarodonon After 6 years, I'm over GraphQL

XML parsers suffer the same fragmentation issues that JSON parsers do.

Go's XML parser straight-up emits broken XML when trying to output tags that have prefixed namespaces.

Xarodonon Ask HN: Why are all major operating systems monolithic?

Lots and lots of home users care more about the few % of performance than the nebulous "extra security".

I have friends who use their desktop for gaming only, literally nothing else, I guarantee they don't care about the extra security a microkernel claims to offer.

You clearly didn't even watch the interview...

James Cameron *is* an expert in deep submersible design/construction.

Because they know the speed of light and the distance between nodes so they can account for the propagation delays of light due to distance.

They're not talking of sub millisecond latency in communications.

Setting up Google alerts for when your company's name gets mentioned on an exceptionally popular discussion board is not special in the slightest.

> How is "Sorry you are having difficulty" a "weasel phrase"?

Because it's trying to avoid accepting any responsibility for a problem that is quite clearly Cloudflare's intentional doing.

This is exactly how I feel too.

If reporting the email as spam is quicker than unsubscribing, that's what I do.

"splinternets" already exist though: https://en.wikipedia.org/wiki/OpenNIC, granted, OpenNIC doesn't have one or more nation-states theoretically backing it. That being said the article takes the alarmism a bit far IMO.

Xarodonon Winssh-Pageant – Proxy Pageant Key Requests to Windows OpenSSH Agent

I made this out of need and a bit of frustration. There are many tools to proxy agent requests from wsl -> windows (pageant or microsoft OpenSSH), but none that I found for pageant -> microsoft OpenSSH. Some windows programs I use only support pageant as a key agent (WinSCP) and I disliked the idea of running two separate key agents for the same keys.

Xarodonon Air-conditioners do great good, but at a high environmental cost

What I wrote isn't hard to understand, I'm sure you understand what I'm getting at.

If you want to be obtuse, be my guest.

P.S - I should've just used "efficiency", that is the correct word, not "energy efficiency"

Xarodonon Air-conditioners do great good, but at a high environmental cost

Ground source heat pumps, AKA what most people call 'geothermal', have their own inefficiencies.

In the winter, when you're using it to heat, it collects heat underground and brings it up to be concentrated and released into your house, this concentration costs energy. Though in the grand scheme of heating your house, any heat generated inside your house isn't a loss. Due to the fact you have to have buried pipe which you pump liquids through, you'll lose some efficiency to head loss and gravity. Those loses happen outside your house too.

Ground source heating is a lot more economical as it uses far less electricity than resistance heating for the same BTU output (because it's "stealing" heat from somewhere else), but it's not more efficient. But if you ask anyone who has to heat their house in the winter, electric heat is the most expensive. It may be efficient, but electricity isn't cheap.

As for cooling, Ground Source Cooling would be more efficient than a conventional AC (as it's not compressing and then evaporating a refrigerant on a coil).

The nice thing about cooling, its greatest demand typically coincides with the best time to collect solar energy. Solar is perfect for offsetting the a/c, they are a great combo in sunny warm climates.

I hadn't ever thought about the double effect of solar panels on your roof protecting your house from heating up by absorbing the sun, and then using that power to cool your house further. That synergy makes me smile.

Xarodonon Air-conditioners do great good, but at a high environmental cost

I think our misunderstanding comes from different meanings of the word efficient (or applying it in different contexts). I think the more accurate word you're looking for economical. Heat pumps for heating may be 5x more economical (use less energy overall, but they aren't as efficient with it), but resistance heating is 100% efficient (if we look at the efficiency after the electricity has left the socket, all that energy turns into heat inside your house; 100% efficient.)

And while heat pumps are transferring energy, there is loss due to inefficiencies. If you're trying to transfer heat from inside to outside, especially when outside is hotter than inside (like in almost every AC scenario), you need to spend energy to compress a refrigerant, cool it, move it inside (meanwhile it's gaining heat during the entire transfer process) and then use it. Also, components like the compressor and radiator fan aren't 100% efficient, and will be giving off heat.

Xarodonon Air-conditioners do great good, but at a high environmental cost

therefore quite a bit more efficient at cooling than oil or electric furnaces are at heating?

To be pedantic, nothing is more energy efficient than electric heat.

All of the electricity that's lost due to inefficiencies in the device turns into heat anyways. Electric heat is the closest thing to 100% efficient we'll ever get.

Whether it's economical, or the best choice is a different matter, but it's certainly energy efficient.

Xarodonon Hello World on z/OS

> The issue I still have with the Mainframe is documentation. Unlike most programming questions a google search does not turn up Stackoverflow results. I find I spend a lot of time going through random forums or reading the IBM doc. I don't find IBM doc easy to understand, but the more I have to deal with it the easier it gets.

You're not alone my friend, those IBM docs certainly are not easy to read/understand.
