jmacd··on You can have geothermal power everywhere if you drill deep enough
For a closed loop system, yes. I think that would be the minimum (6000 sq ft house) at 250ft depths.
jmacd··on Russia 'Likely' to Default on Debts
The smartest defence thinkers I know and/or follow (I worked in the space for a few years, enough to know I didn't want to be there but I did meet some really sharp people) have all switched to a pretty cautious tone in the last few days. Not because they think Ukraine will lose the war necessarily, but that short of a palace coup we need to give someone as unhinged as Putin a way out of this. The "dunking" has been coming fast and furious and for good reason, but we could get to a place where he has no way out but forward. Historically it's rare or non existent that a losing strongman would go out quietly.
jmacd··on You can have geothermal power everywhere if you drill deep enough
You have to make sure it's straight, drop sheathing in to the hole, and then cap it if it isn't going to be used right away.

More importantly, geothermal/ground source is rarely 1 well either, in our case it was 8.

jmacd··on You can have geothermal power everywhere if you drill deep enough
We have a ground source heat pump and one summer we were away and did not use out air conditioning that year much at all. Mid winter our return loop temperatures (the glycol being brought in to our heat pump after circulating in the ground) was at one point 3 degrees C cooler than it had been any other year. Quite a noticeable difference. For reference, our loops are 8 vertical at 250ft.
jmacd··on Here comes the first TikTok war
It seems that much of the Ukrainian cellular network has been left up. No jamming, no outright bombing (at least that is being reported) and the country's internet connections have been left intact.

We have to consider that this is very intentional. There must be some Russian calculus that the wide sharing of content within Ukraine and without serves some purpose. It's possible that Russia sees it as a free intelligence gathering platform.

While this author may feel like this is a level playing field, I don't think that would be a safe assumption if you are actually on the ground in Ukraine.

For anyone wondering what Open Core means, Grist explains their approach: `Grist Labs is an open-core company. We offer Grist hosting as a service, with free and paid plans. We intend to also develop and sell features related to Grist using a proprietary license, targeted at the needs of enterprises with large self-managed installations. `
jmacd··on How we use Notion as a startup
I recently worked at a company that adopted Notion when it was a startup but has now grown to 800'ish people. I can say for certain that Notion does not scale.

The primary issue is very straightforward, but one that plagues so many companies: search.

Searching in Notion doesn't actually exist. It will perform some string matching based on some text you provide, but it is unable to provide any of the needed context in order to decide which result is the right one. It is also aloof of whatever structure you might be trying to impose, so when you are searching you truly are looking for a needle in the haystacks.

jmacd··on UserFront: Auth Without Complexity
I actually thought the landing page was pretty good. It describes the product reasonably well and is very clear about "why pick us". I agree because of the crowded market it is in it needs a very comprehensive comparison section to help people decide why them vs other established solutions.

jmacd··on Ask HN: What made your business take off that you wish you'd done much earlier?
Experimenting with how we price the product and how we bundle/package our plans.

With all other metrics in the business staying the same, it had a massive impact on cash flow and (eventually) profitability.

jmacd··on APIs as Ladders
Your interface must be easy enough for a beginner. Your interface must be flexible enough to continue to be useful as your users' requirements change.

This should be true for your user interface and it should be true in your programmable interface.

The author mentioned SDKs in a passing comment, but it's really the crux of the solution and I think warrants more detail. SDKs allow you to implement language specific versions of APIs which can mask significant complexity and also make the functionality of the API accessible to a much broader group of developers within that language.

They definitely were not doing last mile delivery themselves. They use an outsourced delivery company. Those vans you saw with their logos on them were just part of that deal.
jmacd··on Tesla FSD beta crashes into object [video]
yes. It is probably one of the worst values in the entire automotive industry.

They always have this "buy now, the price will go up later!" but I had to ask myself: how much can the price go up? It's not going to be a $20,000 feature any time soon. I figured I was risking a couple thousand dollars that I would need to pay to upgrade later.

Consumer stupidity is one of the key elements of many frauds.
jmacd··on Tesla FSD beta crashes into object [video]
I've owned 3 teslas. On each of them I have chosen not to pre-pay $10,000 CAD in order to get access to FSD when it is available. 2 of those cars I owned and sold before FSD was even available.

I would not have had the ability to take that license with me to the new car I purchased. I'm surprised this practice hasn't been investigated by any state justice or commerce dept (I'm not sure which it should be in the US?) as many consumers were sold something that was never provided.

jmacd··on Department Press Briefing – February 3, 2022
I will never ever forget watching Colin Powell deliver his Iraq speech. I was a child and very impressionable. I had the Desert Storm trading cards. All of them. I thought wow here is this credible general telling us how how bad these people are.

Years and years later I understood the depravity of his speech and the actions of the "the west" in starting that war. I think it is the only time in my life that I felt truly betrayed, and the realization happened while I was thinking about the topic in a grocery store aisle. My hands felt clammy.

Even more years later my job at a large software company had me extremely close to Powell. Like in the same room with him for long stretches of time and having 1-on-1 conversations. Every fibre in me wanted to say to him, calmly: You told a lie and it killed a lot of innocent people. Their lives matter too.

I didn't say it. I did my job and kept it at that. I don't know to this day if I had a moral obligation to say something, but ultimately I didn't because I knew he didn't care.

So yes, false flags. They only happen when something is inevitable. War is here.

jmacd··on How should net metering affect your electric bill?
The (privatized) power utility in Nova Scotia, Canada just this week proposed a fee of $8/kWh for solar power entering the grid. It was met with a pretty ferocious response to the point the government started re-writing the legislation that governs utility regulation.

https://www.cbc.ca/news/canada/nova-scotia/premier-vows-to-p...

A very large solar industry has been established around these pricing discrepancies. Not easy to undo (and I guess not obvious if it should be undone).

jmacd··on Facebook loses users for the first time
Facebook Groups and Marketplace are both good examples of content graphs. Your social network is irrelevant to them, in fact you may prefer NOT to see the listings made by your friends/family as the negotiation/purchasing is often nicer when it is relatively anonymous. Facebook's one moat is very shallow in this space.

Unlike high attention media with placement and interstitial opportunities, Marketplace and Groups are not great business models.

jmacd··on Facebook loses users for the first time
That is right in terms of the business. For the consumer though, the Social Graph did (and does) have real utility. It just has zero business value now as it isn't even useful for the retargeting data.
jmacd··on Facebook loses users for the first time
There is something else going on around FB.

Almost all activity online has shifted away from the Social Graph to a Content Graph. Almost nobody wants to see what their friends are doing online anymore. In a lot of ways it can be cringey. People just want the latest, catchiest content. TikTok and Youtube are the OGs here, but it's everywhere when you start to look. Twitter timeline changes being an awkward but working example. Discovery > Static friends list.

The entire premise FB was founded on is eroding. This isn't just Apple privacy and some regulatory strangulation. It's seismic to the business. The reason most people are still going to Facebook is incompatible with their primary activities online which is: consuming content from people-you-don't-know.

Facebook is where you find out your highschool friend is super in to a MLM, your uncle has drastic political views you don't share, and that your historical social class and network is largely irrelevant to your life a decade later.

They are doing everything they can to try to move in this direction, but the more they push it the less useful Facebook is for the average user. Instagram's discovery page is a prime example. But Reels are less good than TikTok, and whatever they are doing for short form video in Facebook is surely a hopeless game of catch up. This is classical innovator's dilemma.

The very idea that Zuckerberg straight up said they need to copy the competition harder is incomprehensible considering the resources they have.

They are going to try to do a few things. One is to anti-trust Apple (in the media at least), and the other is to hand wave (Metaverse).

The reason the Metaverse was such a non sequitur is that it is so clearly a last minute thrust coming out of the C-Suite. If you've ever worked at a highly visible tech pubco, you've seen this happen before. Weak quarters mean that product announcements get pushed up. When it is as all encompassing as the Metaverse announcement, you know something is up.

jmacd··on Ask HN: Did I make a mistake jumping on the homestead bandwagon?
It's very difficult. If you don't LOVE it then don't fight it. If you loved it, you'd know. You might still dislike the amount of work or some of the work itself, but I think you'd know.

The other possibility is that you are re-romanticizing city life. Grass is always greener. Perhaps an extended vacation of a month or two back in the city will give you fresh perspective or the certainty you need.

The chutzpah has gone so far that anything proto-crypto is the solution to anything else.

You are right! I actually grew up in Canada and the Ramsay kit shipped from Rochester NY if I remember correctly. 1 Watt was very clearly labeled for Export Only, although still not legal in Canada.

I believe they do still sell the 1watt through distributors (I guess downloading the compliance risk?), at least they did 5 or 6 years ago last I looked.
