The Falkirk Wheel is cool and a fun trip, along with the nearby Kelpies, which were much more striking in person than I'd anticipated.

The wheel is a one-of-a-kind, but there are other ways of avoiding having a ladder of flood locks, see: https://en.wikipedia.org/wiki/Boat_lift

I really liked this one in Peterborough, Ontario, Canada: https://en.wikipedia.org/wiki/Peterborough_Lift_Lock Built as a real working lift lock (originally 1904), rather than as a tourist attraction. Powered by a little bit of extra water in one of the buckets to tip the balance and drive the pistons.

There's also another unusual way - the Caisson lock.

Its design is TERRIFYING.

The boat is floated into a tube that get sealed at both ends and then (in the dark..) that tube is winched down into a completely flooded chamber until it (hopefully) lines up with the egress port at the bottom. The tube with the boat in is unsealed and the boat floats out.

I recently built something[1] similar, though with far less effort and sophistication than the author. The goal was to have a plug-and-play audiobook player for an elderly family member with impaired vision. In retrospect, it would have been better to adapt an old phone or tablet with a macropad rather than build this on top of an espmuse speaker[2].

I keep thinking that a cassette player would be the ideal interface for something like this. The controls are as obvious and as tactile as it gets and the whole analog-mechanical experience is familiar to folks from that generation. If only tapes could hold more than two hours of audio ...

Could something like [1] work? My understanding is it's a "fake tape" that has an SD slot and can be used in any player.

Dyac commented on What should I expect from moving tech jobs from USA to Europe? · Posted by u/tech_lizzard

NicoJuicy · a year ago

Yeah, having kids and working till 23:00 perhaps ain't possible.

For Europeans and Americans;)

Dyac · a year ago

Typically you don't work straight till 23:00, you just might log back on later in the evening (perhaps after putting the kids to bed) to finish up something when you know you'll get quiet time, or to align with colleagues in the AMER or APAC regions etc.

What I miss from this type of apps, including notion, is the ability to "inherit" properties from databases.

I would like, for example, to create a superdb with basic task properties (title, deadline) and then create subdatabases that add more project-specific properties.

This, I'll be able to create a single view with all my tasks for the day in a single place, but also add all the info I need for individual tasks.

Unfortunately, for some reason, nobody (that I know of) built something like this into their apps.

I think Tana can do this with the "supertags" feature.

Dyac commented on Communicating Software Estimates apsis.io/blog/2016/04/18/... · Posted by u/wkirby

The best estimates I’ve found are “This will take: days, weeks, months, years”. No numeric values allowed. Yes, you can’t do (inherently faulty) math on these estimates to arrive at aggregate metrics: this is a feature. However, it still allows you to meaningfully schedule work.

Dyac · a year ago

If pushed, I get my developers to give estimates in jumps of ~5x.

Their options are

2 days 2 weeks 2 months 10 months

Then I triple the estimates before sharing with the business.

We don't estimate individual tickets/bugs at all, just overarching projects.

I also ask the business to estimate the commercial/user impact of the projects too, and we track and report the reality against their estimate, to hold a bit of a mirror up to them and as a way of pushing back on doing pointless work. Those estimates we use similar orders of magnitude for - £1k, £10k, £100k, £1m, £10m.

Fermi estimations like these really help avoid protracted negotiations and the lack of precision is a feature that makes clear they are estimated.

Dyac · a year ago

Hi. I have wanted something like this for YEARS, but have never had the motivation to hack something together.

A few questions:

1. Is the dev edition hardware different?

2. If not, it possible to upgrade to a dev edition later, ie. Is it just a config thing on the server end?

3. If I have multiple trmnls how do I manage them? Is it possible? Do I need multiple accounts? Do they show the same stuff etc? Is "dev edition" for my account or per-device?

4. Using multiple apps - is it a split screen display, or do it cycle through the apps every x seconds? Is there a button to advance to the next one?

5. What's the resolution in real terms? Ie. Can I get a full month calendar to show and still be able to read entries? How many lines of Todo-list items can I have? What happens to over-flowed items?

6. how does it get updates? does it connect to my phone via Bluetooth or to my WiFi? Can it store multiple WiFi networks, for if I want to take it places?

Fair play, that is impressive. I am generally underwhelmed by Shopify, seeing them as another vulture capitalist way of leeching money out of small businesses the globe over, but props to this animation. Even the work gone into making the blog post is extremely impressive.

Dyac · a year ago

As someone who has worked in ecommerce for decades, Shopify is fantastic.

It's not the cheapest, nor is it the most expensive. It's not as powerful as some systems, but it's not weak. It's not the easiest system to work with, but it's also not the hardest.

What it is is right in the goldilocks zone, and it allows businesses to DO BUSINESS, not end up having to worry about or even think about many decisions.

Day-to-day I work across 4 ecommerce platforms and Shopify is the one that doesn't keep anyone awake at night and "just works". Sure there's a ton more stuff some of the other platforms we use can do, but we also have a LOT more meetings, dev tickets and headaches with those platforms.

For like 80%+ of 0 to $50m+ online businesses it is by far the best choice because it means the team can focus on connecting with potential customers and selling stuff and not have to allocate nearly as much time or headspace to the Storefront system.

My dream program is a tool that takes a video of a game on a pool table and feeds it into an interactive playback tool like this one.

There's dozens of awesome shots I wish I could experience again on demand.

An engineer created a mixed reality pool table (YouTube channel "Stuff Made Here", all of his stuff is great).

#2 is a slippery slope if you don't do it properly.

You might look end up looking at lots of different slices of your data, and you might come to the conclusion, "Oh, it looks like France is statistically significant negative on our new signup flow changes".

It's important to make sure you have a hypothesis for the given slice before you start the experiment and not just hunt for outliers after the fact, or otherwise you're just p-hacking [1].

Dyac · 2 years ago

Fundamentally, you can't use the same data to both generate and validate/disprove a hypothesis.

Srgmenting and data dredging is fine provided you run a new test with fresh data to validate if there is a causal relationship in any correlations found.
