Ah thanks for finding the name, I tried to describe it in an older comment [1], on the same topic of Framework laptop expansions.

Agree with you, I hope such a version exists one day!

And during a brief period, I also had a windows phone, where you could say "Call Cortana". Cortana was registered as a fake contact behind the scenes, and all it would do is trigger the Cortana assistant through that phone call. You'd then tell Cortana what you wanted, and it had much better voice recognition and capabilities than Sync, so it did what you wanted 99% of the time. It was pretty cool.

Of course it was annoying and a waste of time as you had to always make that call first, but I'm glad the engineers on Cortana remembered that "all problems in computer science can be solved by another level of indirection"!

The terminal was unresponsive and displaying the following error: "cannot connect to mainframe" (This was in 2019).

Specifically, how to make the sum of all monitored "pillars" more useful than each of them individually.

3 major pillars being:

- Metrics (whether application or higher-level of the stack, like OS)

- Logs (whether structured or unstructured)

- Traces

Observability is these major pillars and how to easily "jump" from one to another to very quickly identify the root cause of an issue. I.e. go Metrics <-> Logs, Logs <-> Traces, or Metrics <-> Traces,

For instance, with good Metrics, one can easily figure out & get alerts when there is a large spike of 500 errors. But when Metrics & Logs can work together, one can easily see the exception from stack trace that are emitted with those 500 errors.

Similarly, with good Metrics, one can easily figure out that the frontend service latency p90 has increased by 5x. But with Metrics & Traces working together(for instance via Exemplar[1]), one can look at a bunch of the traces that have a very high latency, and identify the upstream service responsible for this increase.

With Monitoring only, you could get a nice Metrics solution in place, with fancy alerting rules, but all it was good at is informing you "Something bad is currently happening". With a good "Observability" setup, you should also be able to change it to "Something bad is currently happening and the root cause is right here."

I definitely filter those out.

About once every 6 months the tweets "liked" by people I follow pop up again, it's usually very noticable as the feeds quality turns down dramatically.

To get rid of those, I do the "..." > "I don't like this tweet" > "show fewer likes from XYZ" on 2 or 3 tweets, and they're all gone for another few months.

It's not ideal, a settings menu where you can disable those permanently would be far better, but it works.

That's funny I remember laptops from the 2000s with those swappable cards with different ports.

One I distinctly remember because it was clever way to keep the card ~3mm thin were the Ethernet cards, where the Ethernet port was hidden inside and you'd press it to make it pop, similar to handleless kitchen cabinets.

I found a picture of those on Wikipedia: https://en.m.wikipedia.org/wiki/PC_Card The framework expansion port seems to be a 2021 version of this, although I don't know how standardized these new ones are.

EDIT: From the framework's configuration page:

> > Will you be adding additional Expansion Card types?

> Yes! We'll be adding new Expansion Cards over time, and we're also opening up the design to enable third parties and community members to create their own versions. We'll be making these available in the Framework Marketplace

That's awesome, then in theory Ethernet expansion card could exist (and use similar design to the PC cards above, where the Ethernet port can be retractable)

You can basically take 101 intro course of any field from great universities. And if you want to go deeper, the advances courses on a university's page usually have syllabus, with recommended readings etc.

It's basically like a coding whiteboard interview, but instead of being asked to invert a binary tree, you're asked a math question (proof of something, etc)

It doesn't seem to be the main reason, otherwise how can you explain Sublime text popularity prior to VSCode?

The tunnels and their exits next to interstate highway already exist per the article, so at this point the construction costs are assumed to be negligible (compared to a "$2.6 billion and take thirty years to build" system quoted in [1])

it would be used exactly like it was in Seattle: as a shortcut through the city for some routes. The bus retains all its advantages outside the tunnel, it's basically an underground dedicated bus lane.

If really popular then it can get upgraded to a real train, like it was done in Seattle.

[1] https://en.m.wikipedia.org/wiki/Cincinnati_Subway

> The DSTT was used only by buses from its opening in 1990 until 2005, and shared by buses and light rail from 2009 until 2019

That's 15 years with bus only, then 10 years of shared bus/train.

In this case, Buses can drive in the underground tunnels that were built for this subway, can't they? Seattle did it for many years until they replaced it with trains: https://m.youtube.com/watch?v=etT_wVuKy_I

In that case, the only thing slowing down the bus is speed limits, which are probably a bit lower than a train, since train would be safe on rails, but still I wonder why they didn't use that given that the tunnels are here and in good condition

Why not use buses in those tunnels as well? Maybe there is no traffic jams above ground?

You can use QWERTY with accents very easily with "International keyboard with dead keys"[1]. You can configure OS to switch keyboard with Alt+Shift to have the regular QWERTY and the International-QWERTY when you need it.
