noria VS Windows Terminal

> Automatically managed, application-transparent, physical denormalisation entirely managed by the database is something I am very, very interested in.

Sounds a bit like Noria: https://github.com/mit-pdos/noria

It feels more than a little bit coincidental to call it Noria when https://github.com/mit-pdos/noria exists (and has been posted about here on HN)... especially with the whole bit about incrementally computing changes.

Is this similar in spirit to Noria?

I assume you have studied Noria? https://github.com/mit-pdos/noria

If you want to look how databases are implemented in rust try https://github.com/mit-pdos/noria

Only tangentially related, but I wondered what were the difference between ReadySet and Noria, and they address this exact question in their repository I'm really glad to know that the ideas behind Noria didn't die when Noria was abandoned after /u/jonhoo graduated.

:wave: Author of the paper this work is based on here.

I'm so excited to see dynamic, partially-stateful data-flow for incremental materialized view maintenance becoming more wide-spread! I continue to think it's a _great_ idea, and the speed-ups (and complexity reduction) it can yield are pretty immense, so seeing more folks building on the idea makes me very happy.

The PlanetScale blog post references my original "Noria" OSDI paper (https://pdos.csail.mit.edu/papers/noria:osdi18.pdf), but I'd actually recommend my PhD thesis instead (https://jon.thesquareplanet.com/papers/phd-thesis.pdf), as it goes much deeper about some of the technical challenges and solutions involved. It also has a chapter (Appendix A) that covers how it all works by analogy, which the less-technical among the audience may appreciate :) A recording of my thesis defense on this, which may be more digestible than the thesis itself, is also online at https://www.youtube.com/watch?v=GctxvSPIfr8, as well as a shorter talk from a few years earlier at https://www.youtube.com/watch?v=s19G6n0UjsM. And the Noria research prototype (written in Rust) is on GitHub: https://github.com/mit-pdos/noria.

As others have already mentioned in the comments, I co-founded ReadySet (https://readyset.io/) shortly after graduating specifically to build off of Noria, and they're doing amazing work to provide these kinds of speed-ups for general-purpose relational databases. If you're using one of those, it's worth giving ReadySet a look to get these kinds of speedups there! It's also source-available @ https://github.com/readysettech/readyset if you're curious.

It seems similar to MIT's Noria [1]

> Noria is a new streaming data-flow system designed to act as a fast storage backend for read-heavy web applications based on Jon Gjengset's Phd Thesis, as well as this paper from OSDI'18. It acts like a database, but precomputes and caches relational query results so that reads are blazingly fast. Noria automatically keeps cached results up-to-date as the underlying data, stored in persistent base tables, change. Noria uses partially-stateful data-flow to reduce memory overhead, and supports dynamic, runtime data-flow and query change.

Materialize is really neat, also checkout https://github.com/mit-pdos/noria. It inverts the query problem and processes the data on insert. Exactly like what most applications end up doing using a no-sql solution.

A Microsoft employee recently (~6 months) opened a Github issue to discuss a command line editor for Windows: https://github.com/microsoft/terminal/discussions/16440

> convince management of the value

This presupposes that such convincing is even possible. Many, many companies have leadership that are simply terrible at identifying value. If you've never been part of a majority of developers advocating for, if not outright begging for, some huge ROI initiative to get the green light, you are very fortunate.

There are great counterexamples, like Valve, which is known for giving developers an extreme degree of autonomy, and they benefit greatly from that approach. For each Valve, though, there are dozens of companies that manage to succeed despite themselves.

Take Microsoft, for example. One tiny, yet representative, example: the way the Windows Terminal team handled a suggestion from Casey Muratori to take their software from abysmally slow to lightning fast:

https://github.com/microsoft/terminal/issues/10362

A quote from one of the Terminal developers, dismissing the suggestion:

> I believe what you’re doing is describing something that might be considered an entire doctoral research project in performant terminal emulation as “extremely simple” somewhat combatively…

Just how difficult was such an endeavor in actuality? Well, given that Casey implemented his own terminal emulator from scratch and incorporated the functionality he was proposing in a mere weekend... not a whole lot. Relatively minor effort for a huge return on investment. It took Casey explaining the concepts, then providing a working proof of concept, and finally a bunch of backlash online towards the Terminal team to get them to do the right thing for themselves and their users.

At this point ConHost.exe is open source [0] so it is maybe not a stretch to expect Microsoft to open source CMD.EXE at some point.

Though with PowerShell being cross-platform and already open source, I personally don't think there's enough to gain in some sort of better open source CMD.EXE fork. I'd be interested in being proved wrong on that, but I'm also happy enough with PowerShell these days I'm not in a hurry to return to CMD.EXE.

"Users of Linux and macOS may well be familiar with the sudo command, used regularly in the terminal, and it looks like Windows may finally be getting its own version."

More Linux tools are coming to Windows, especially Windows Server because the tools are good and they make it easier to administer a Windows Server.

They are looking at adding a default TUI text editor (https://github.com/microsoft/terminal/discussions/16440) and now they are adding sudo.

I would not be surprised if systemd or something like it gets ported or reinvented for Windows simply because it makes managing services so nice.

GitHub

>We are allowed to view and consume it, to be influenced by it, and under many circumstances even outright copy it.

People keep saying this but it's actually much more complicated, and in many cases you can't view copyrighted content.

An example, MicroSoft employees are not permitted to view or learn from an open source (GPL-2) terminal emulator:

https://github.com/microsoft/terminal/issues/10462#issuecomm...

Another example is proprietary software that may have it's source available, either intentionally or not. If you view this and then work on something related to it, like WINE for example, you are definitely at risk of being successfully sued.

If you worked at MicroSoft and worked on Windows, you would not be able to participate in WINE development at all without violating copyright.

If you viewed leaked Windows source code you also would not be able to participate in WINE development.

An interesting question that I have, is whether training on proprietary, non-trade-secret sources would be allowed. Something like unreal engine, where you can view the source but it's still proprietary.

Windows Terminal is pretty good and a new terminal emulator written in the last few years. No smooth scrolling, here's the GitHub issue requesting it: https://github.com/microsoft/terminal/issues/1400

Assume its related to this:

https://github.com/microsoft/terminal/issues/10362

It's nothing serious just microsoft engineers writing slow as shit code and reacting poorly to someone trying to help.

"There are plenty of offline scenarios where this would be incredibly useful. For disconnected environments, etc. There are some environments that will never connect to winget."
