> Regardless, a retractable "XJACK"[0] from the PCMCIA days might have been a better choice for this

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!

For me, Sync only worked well to make phone calls ("Call Joe")

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"!


It might be network slowness, one day at the rental counter all the paperwork had to be done by hand (and visa contacted by phone to process payment) because their system was down. It took a literal hour.

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


Observability isn't just a rebranding of Monitoring, it's Monitoring + making it the most actionnable possible via standardization.

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."

logs, traces and profiling were all viable parts of a good monitoring stack even prior to the term observability being coined.


That’s trope #1 right there :-)


> but get fed with all of their garbage "liked" content and can't filter that out.

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.


> The little modular port attachments seemed like a novelty at first, but now it feels absurd that you'd buy a laptop with a bunch of "hardcoded" ports that you can't ever change

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)


those PCMCIA cards were very expensive.


If you're looking for an actual demo of the product, it seems that the weather map on https://www.msn.com/en-us/weather/maps?lat=47.6032&lon=-122.... is powered by leaflet. I really like the work they've done with the wind animations and historical air quality maps


That's pretty cool, it reminded me of Windy which is also pretty awesome. In fact, peeking at the source of windy, it looks like it also uses Leaflet!

https://www.windy.com


I just discovered that the other week when I was looking for a KML plugin for Leaflet. Windy maintains one!

https://github.com/windycom/leaflet-kml


Interesting that Windy uses a version from 2018. (v1.4)


Its very heavily customised.


Hot damn, an online weather page that doesn't perform like I'm trying to load the radar view over a 56k modem.


Right, that's something I was wondering when Boom was announced a few years back [1]. Will radiation be even worse for the crew if the plane body is made of carbon-fiber vs thicker metal like the Concorde was?

MOOCs are really great for appeasing your FOMO in that area and giving you a more well-rounded education!

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.


Not familiar with old Russian system but there are oral exams for math in France when you apply to "École d'ingénieurs" (engineering school), and it still exists today:

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)
