sco1··on Show HN: Git, from scratch, in Python, Spelled out
I've lost the HN link now but a while ago there was also a tutorial featured that walked through how git works using Python: https://www.leshenko.net/p/ugit/

sco1··on Cog: Use Python in your source files to generate pieces of code (2021)
+1 for enumerating CLI options in markdown files. I commonly forget to update my READMEs when making changes to the interface and cog has been a really helpful utility to take care of this for me. I include this pattern in pretty much every tool I make nowadays, honestly probably inspired by your blog post on the topic :)

This year I also realized I could use it for my Advent of Code repository to sync my yearly progress tracker with a summary table in the base directory's README: https://github.com/sco1/adventofcode/commit/9b14483fc3d9ef58... .

sco1··on Army ants use collective intelligence to build bridges
My favorite ant behavior is that many tree-dwelling species will actively glide back towards the trunk if they're dislodged so they're less likely to depart the tree entirely. There's a few papers on the topic, this article has some videos :) https://insider.si.edu/2011/06/lofty-experiments-with-glidin...

I didn't see it when I searched, so apologies if I overlooked it.

sco1··on Blue Lagoon geothermal spa in Iceland closes after series of earthquakes
I recently stayed at the sister resort, the Silica Hotel, and found it quite pleasant. It has its own lagoon and it’s a much quieter experience. It’s a 5 minute walk from the main resort so you can still take advantage of all the accommodations.

sco1··on Uber, DoorDash Sue NYC to Stop Delivery Drivers from Getting a Minimum Wage
> obviously people don't want to pay a 12$ delivery fee for an order of $20

I realize there's psychology at play here but to an extent aren't we already doing that through essentially obligatory tips?

> As such it would help people a lot more if there was an easy path towards acquiring skills, guaranteeing that these bottom-rung jobs will be only temporary

When the service industry worker has to spend all their time working in order to make even a marginally livable wage the path is to pay them more money, directly or indirectly. The problem is exacerbated in high COL areas, and sure you can say "ok well just move", but broadly speaking you still need someone to do these tasks and that pool is dwindling.

sco1··on Apollo will close down on June 30th
> By acquiring Apollo Reddit could monetize those users through Apollo instead of the official Reddit app.

After what Reddit did to Alien Blue I don't know how many Apollo users would be too keen on playing that game again. I personally have no confidence that a Reddit owned Apollo would retain what makes the current app great.

> How does Apple's refunds work?

I don't know how monthly subscriptions work, but yearly subscription refunds are pro-rated.

> I'm surprised more people don't do one-time purchases to avoid these subscription refund stories I keep hearing

I'm not, at least not for apps like this that need consistent revenue to support regular maintenance and/or server costs in an era where customers balk when an app costs more than a few dollars. To achieve this you end up balancing whether or not to serve ads, hope you can just grow enough new users forever, charge for major updates, charge a subscription, or beg for tips. While there are some exceptions, you can probably tell that ads or subscriptions are generally winning this nowadays.

One-time purchases are a tricky thing, since you've realisitcally now precluded ever charging for a major update. This is great for them, and might be for you if you've gotten your math right, but if you haven't (or it changes) then you're stuck. And, for better or for worse, they tend to be the loudest users.

Marco Arment talks about this balance in general on an episode of the Accidental Tech Podcast a couple weeks ago when discussing how Casey (another host) should price an app he's writing. For context if folks aren't aware, Marco created Overcast, which is a popular 3rd party iOS podcast app. The discussion spans a couple episodes but I the post-show of [Episode 535](https://atp.fm/535) captures the gist.

sco1··on Peloton CEO quit after laying off 2,800. A lesson about how not to lead (2022)
I've owned the bike for 3 years and IMO Peloton's value is the class content, not the device. I've mentioned it before on HN and having tried many services over the years, I don't think anyone but Apple has even come close to providing the same kind of consistent value for general fitness instruction, and they had Peloton's product to draw from when they created it.

I don't think I'm alone in finding the task of designing workout plans challenging, and often demotivating. Obviously it's not the same as paying for coaching or personal training, but being able to open up the app and just have a workout ready to go is valuable to me. I understand some being miffed that the subscription cost is higher for those who own Peloton hardware, but the price point is still much lower than what I would be paying (and was paying) for local classes.

I don't know if this is valuable enough to sustain the business, but I hope it is.

sco1··on GM’s decision to ditch Apple CarPlay, Android Auto sparks backlash
> You had to manually update the map database every year.

Now you have the added bonus of gambling on whether or not the maps are actually updated. My SO wanted to update the maps in their Jeep since all the exit numbers around us had changed. Not only did the install take hours, the exit numbers were still the old ones. Hooray!

Jeep just threw up their hands because the license key had been used; total racket.

sco1··on GNU Octave
> but what’s the benefit of going with a walled off proprietary $$$ tool when you can use something like this

My day-to-day stack nowadays is mostly Python with a smattering of others, but I’ve been using MATLAB for almost 15 years.

Like any other enterprise software, you’re paying for support and generally very good documentation. If you have a technical issue or even just a development question you get a response from a human within a day or two, often just a few hours.

There are also many domain-specific tools (e.g. Simulink) that do not have similarly functional open alternatives. Octave is great, but can lag behind new language features and generally isn’t 100% cross compatible. Whether or not this affects you is really dependent on your use case.

sco1··on Peloton replaces CEO and lays off 2,800 people
> Peloton forgot how easily they can be replaced.

Maybe on the hardware side, but I don't know if the same can be said for their content. Having tried many, I don't know if anyone but Apple has even come close to providing the same kind of consistent value for general fitness instruction.

sco1··on WeWork CEO Says Least Engaged Employees Enjoy Working from Home
> This suggests a potentially disturbing trend -- companies or managers that will start implicitly punishing employees for working remotely.

> My guess is that even at companies that officially support partial remote time employees will start to feel some pressure for taking advantage of it.

I'm sure it's not the same in all sectors, but in the govt realm I was feeling this before the pandemic, with the pandemic flipping it completely (for now, at least). We have a long approval chain to get authorization to work remotely, with an explicit time code to go with it. I felt almost guilty requesting up to 2 days a week remotely and almost never took more than 1.

Then the pandemic hit and management discovered that a lot of people didn't need to sit in a cubicle 5 days a week to get their jobs done. There's even rumblings from higher up the chain to emphasize getting work done where it's most efficient; hopefully that translates to a better attitude towards working remotely.

This has come up from a Core Developer before [1] so it's not just code golfers having a laugh.

Yes, the docs note the tokenization behavior [2], but Guido's response today in the above mail thread is also pretty unambiguous:
