It doesn't look like this is available just yet. I can't wait to see more details when it comes out.

I have a JetKVM (https://jetkvm.com/) and it's been absolutely fantastic. I'm still waiting on the ATX expansion board, but the core unit is used to monitor my homeserver.


Can a single JetKVM control multiple computers? I have several AI training machines that occasionally got stuck and need a power cycle. Most of the time this happened when I’m out of town so it has been annoying.


It can only control one set of monitor/hid but through the extension port you could wire up something for multiple computers power buttons (the ATX module mentioned by GP uses a rp2040, which has plenty of GPIOs).

I think it would be simpler to buy a network PDU (or iot plugs) for your use case, assuming the computers can be set to power-on automatically.


These look great, but if you missed the Kickstarter boat and you're only just finding out about them today; how do you buy one?


Wait. My theory was that they were so popular making a solution like this, that they were overwhelmed with orders. Kinda like how Framework have a 3-6 month wait from order to delivery.

I'm guessing they're getting through the kickstarter batch and then they're going to launch a store, particularly once they get all the bugs worked out of the manufacturing process.

I kinda would like to see a DP over USB-C version so keyboard, mouse, video, and power all go over one cable.


This looks pretty great. The UI looked fantastic, and the post mentioned that it was open source. However what's open source appears to be the DuckDB extension, which forwards the requests to a remote URL. I've not been able to find the code for the actual UI.

Is the actual UI open source, or is that something MotherDuck is allowing to be used by this while remaining proprietary? Right now it doesn't appear like this would work without an internet connection.


Yeah, this is really concerning. The handwaving around "keeping the ui up to date" by hosting it on ui.duckdb.org instead of embedding it doesn't taste great to me.

At least it's hosted on duckdb.org and not mother duck, but I really would expect to see that source somewhere. Disappointing unless I've missed it.

Breadcrumbs in the extension src: https://github.com/duckdb/duckdb-ui/blob/963e0e4d4c6f84b2536...


Yes. So confirmation from Jeff Raymakers, a software engineer at MotherDuck, the UI is not open source.

I was so excited. I knew it was too good to be true.

Something like this will basically destroy legacy platforms like tableau, sas etc


How is this promoted as a "local UI" if it gets the UI from a remote URL?

Maybe the closed source UI is downloaded upon first execution for installation and then cached locally?

Or is this a web app that loads from the remote URL each time?


It's a web interface, but it is served from the local machine. The default is http://localhost:4213/

See the note just above this link on data locations and the optional and explicit opt-in to motherduck:

https://duckdb.org/2025/03/12/duckdb-ui.html#features


The docs say that the extension's server is configured here: https://duckdb.org/docs/stable/extensions/ui#remote-url

But yeah, I can't find docs nor source for the UI. And the extension docs refer to MotherDuck's own UI: https://motherduck.com/docs/getting-started/motherduck-quick...

So, a bit confusing way this is set up.


It’s quite funny the docs also say this about the configurable url:

> Be sure you trust any URL you configure, as the application can access the data you load into DuckDB.

That’s certainly not what I would expect if someone gave me a “local UI” for some database. I’ve only just once toyed with duckdb, was planning to look more at it - looks like will need to have my guard and see what actually is “local” and doesn’t ship my data to a remote url.


I'm a co-author of the blog post. I agree that the wording was confusing – apologies for the confusion. I added a note at the end:

> The repository does not contain the source code for the frontend, which is currently not available as open-source. Releasing it as open-source is under consideration.


Some people work in serious work environments, on heavily regulated data. Thanks for another software landmine !

Make it opt-in, or not installed by default please, it’s so hazardous.


The actual UI is not open source.

(Someone could write an actually open source UI extension for duckdb, but that would require a lot of investment that so far only motherduck has been able to provide.)


I've looked at quite a few options, and this one (the product of a single person) is a great base, and MIT licensed: https://github.com/caioricciuti/duck-ui

If you want to support a real OS UI take a look.


I’ll never understand how any UI projects don’t include an actual screenshot of their project as the first thing on their landing page. It seems so obvious.


I find the SqlLab in apache superset to be very good, and I have duckdb as a data source (anything that supports SqlAlchemy works). It works very well. To be honest, when I first saw the screenshot, I thought it was SqlLab. I haven't actually tried the duckdb ui, though.


That is really interesting. I am thinking of toying with same combination for my small project. Can you share a bit on your use case? Would love to know more.


And so the malware-izarion of duckdb begins. Investors need revenue I guess.


Honestly I hope they keep some things proprietary. Just making everything FOSS is not a sustainable business model, and I would quite like DuckDB to continue to exist.

I have similar concerns for Astral. Frankly they're single-handedly unshitifying Python, and it would be a tragedy if they run out of money and we're back to dealing with Pip.


So just to clarify, it's not really a local UI, ie I can't use it on an airgapped machine?


Concur, this is rather confusing wording and the GUI components are closed source as far as I can see.


Does this work with Flutter, or does it only work with Android native apps?


it works with flutter. we many active flutter developers in our discord too that will flame us if we introduce any bugs for them. its good because then we can fix this asap.

same is true for intellij and kotlin/java support


Relational databases are not the preferred storage mechanism at Amazon. If a team wants to use an OLTP relational database it’s possible that it will be a decision they will need to defend at any kind of design review.

Of course there are relational databases running OLTP workloads, but it’s far away from the norm. There was a program a while ago to shift many RDBMS systems onto something else.


So they do joins in code rather than SQL? Wouldn't that risk hiding scaling problems?


It can but it's usually more obvious what's happening with code and how to fix it. Amazon wants you to think about the scaling issues while building as they don't want to lose the area under the customer curve on the far right.

The theory is that with rdbms you have a magical box that scales vertically until it doesn't. And when it doesn't all you can do is scale back the customers until you fix it with sharding or a re-architecture. Basically you tend to hang yourself with indexes and transactions. Also generally when an RDBMS fails it fails down to like 30% throughput.


I recently finished a contract at a company who has gone full on dynamo with the idea that if we have slow queries and dynamo is good for Amazon, then it's good for us too. I've ran some explain on the queries causing issues and of course those queries didn't leverage indexes like they thought ....


How did you run explain queries on DynamoDB? Or may be you mean something different and I misunderstood you?


I ran explain on the original mysql implementation. The basis of the migration project to dynamo was mysql couldn't cope with our scale but that was bullshit


That doesn't make sense, you have to specify the index when you're using Dynamo.


You can do scan operations and if they use PartiQL it hides whether you are using indexes.

I usually have an explicit DENY for dynamodb:Scan for the IAM role used to access the DDB table


Look up design patterns in DynamoDB. If you know your access patterns and you often do with well defined microservices. You don’t need to do joins.


Amazon Retail has multiple systems to allow you to basically use SQL across databases (eg Datapath).

I’m not sure about AWS.


Seems like Microsoft is intentionally doing a leftpad. One day people are going to wake up and a host of CI pipelines and the like will start failing.

NPM, Maven and other package management systems don't generally allow revoking older libraries for security flaws. The pain from this if it goes through will be felt widely.


Why do you call these other languages “better”? They’re different, but I’m not sure why either of the one’s you mentioned would be better for this use case.


Modern config languages offer strong validation and advanced IDE support, which is essential for a great user experience.

What is the double hack used in OpenHFT? I tried looking this up and came up short.


https://github.com/OpenHFT/Chronicle-Core/blob/ea/src/main/j...

(see roundN)

Be careful and use it only if you know what you are doing and understand the limitations.


I’ll byte. Perhaps you didn’t look long enough. I’m sure the answer will float by at some point.


Yeah, went through a whole journey getting this to work on a NixOS guest with a Proxmox host recently.

You reminded me to write up the process, and publish a flake for NixOS users who want the kernel.


Lots of quantitative research uses R. It’s still very popular in the industry.

Insurance is also still using a lot of R. Actuaries I know still use it, and they talk of Python, but I don’t see anyone actually moving to using Python.
