You may be able to get close with sufficiently small row groups, but you will have to do some tests. You can do this in a few hours of work, by taking some sensor data, sorting it by the identifier and then writing it to parquet with one row group per sensor. You can do this with the ParquetWriter class in PyArrow, or something else that allows you fine grained control of how the file is written. I just checked and saw that you can have around 7 million row groups per file, so you should be fine.

Then spin up duckdb and do some performance tests. I’m not sure this will work, there is some overheard with reading parquet, which is why it is discouraged to have small files and row groups.
Still don't understand the argument as they are inherently the same thing.

What I gather is they are teaching students how to research case law and the medium is completely irrelevant to that task. I suspect the concept is the most important part.

Though, as always, I'm probably completely wrong and this is just some gatekeeping conspiracy to keep the ranks of people with knowledge of the law artificially low.

There's a massive shady component of discord inherent to how access and security are at the whim of ar arbitrary discord mods. All manner of illegal activity thrives behind custom access control.

The most notable instance in media is the leaking of classified materials, the creation of swatting/ddos communities which gave us the 'BigBalls' hacker employed by doge,

But more sickeningly, recently it allowed this doctor to successfully target countless children, including convincing a 13 year old girl to hang herself in a live discord call. [0]

There is a problem with too much protection of freedom and secrecy.

No, that $15M is for the analysis platform at EPA. Adding embassy data to it did not cost $15M, and turning it off now certainly does not save $15M. Turning off the embassy data now merely prevents us from getting the most out of that $15M.

And if $15M seems like a lot, check out all the boondoggles that are par for the course in large corporations. The EPA system is a marvel of efficiency compared to what is frequently seen at large well-funded.

And if there actually is incompetence that resulted in overspending on the system, the financially prudent response would be to replace the decision makers rather than limiting the functionality of the existing system. The sunk-cost fallacy is endemic in these sort of low-information cost-cuts that actually end up costing us far far more than they save us, all so the outside consultants can pretend that they are doing something g to save a company.
> It is not like water flowing in a direction guided by the terrain.

I understand it doesn’t seem intuitive at first, but evolution is actually quite similar to that.

> Trees produce thorns to keep away animals.

It's not that trees consciously produce thorns to keep animals away. Rather, trees with thorns (due to random mutations) are more likely to survive because they are less likely to be disturbed by animals. Over time, those trees are more likely to reproduce and pass on those traits.

Just like water flows down the path of least resistance, evolution naturally selects for traits that improve survival. The "selecting" we are referring to is used in the same sense that water "selects" which route it takes. It doesn't actually select anything, it's just following the laws of physics.
(Leaflet cofounder here) - thank you, really nice to hear! It's taken us a long time and several prior products/prototypes to arrive at this, including previous attempts where we had similar aims — make nice expressive spaces for collaboration, creative work, learning — but took very different (and more complicated) directions, e.g. a multi-room chat/note hybrid app with each project as its own database, or a global wiki with live calls built in.

I think Leaflet's by far the most easy to use but also hides a lot of power and expressive potential without being overwhelming, and we're seeing more traction and cool ways people are using, so happy with it so far! In particular finding it really cool how there's a lot of space between very simple notes/docs and rich publishing that gets closer to artifacts more like whole websites but with document-like form factor. And making something that's equally nice and simple to read and to edit/collaborate on with others…a good challenge and design space to explore!
Russian disinformation floods AI chatbots, study finds
The admin interface is pretty, the webmail interface is ugly
I didn't see federation mentioned anywhere, just self hosting. The difference:

- Self hosted means everyone has their own server, people need to register for the server they're interested in using. Websites are an example of this: you host your own system independently of anything else going on (though there are hyperlinks to cross-link content, which aren't necessarily present in other self-hosted software). Git servers are another example, like Gitea or Forgejo or Gitlab or gitweb

- Federated usually lets you connect servers, so that if I'm on HN and want to post a comment on a Reddit thread, if they were federating, I could just do that without logging into reddit specifically (let alone registering a completely separate account for the other server). The best example may be email, where I don't need to register with Google (yet) to send a Google user an email but I specify @gmail.com after the user's name. A more recent popular example is Mastodon

Each has upsides and downsides, like having to moderate content from other servers and having a much more complex protocol (federated) versus being independent and simple but also being another walled garden (self hosted)

Edit: confirmed by https://news.ycombinator.com/item?id=43278375

> when someone posts here about saving 10k in AWS spend, when their company does millions in revenue and the engineer cost at least 100/hour

So if you have a bunch of machines you don't need anymore on AWS, you just leave them on, because it's only 0.5% of the total AWS spend? nevermind the potential attack surface of machines that aren't being actively maintained, are still connected to your other services, and so on?

For sure. At Cenote, we’re obsessed with ensuring our software delivers real value to clinics, rather than just adding another point solution—or worse, overwhelming them with multiple fragmented tools. As mentioned in another thread, many of these clinics aren’t the most tech-forward, and we've found that in-person discussions often reshape our bundle (e.g., prioritizing referral intake over insurance verification). This tailored approach ironically simplifies integration and maximizes ROI for our customers.

> and for whatever reasons that one app must be iMessage

iMessage isn't an app. It's just the Messages app, and the reason it's that app is because it's the SMS app.

There's zero effort to using Messages. It just works, and it just works to communicate with everyone because it will always fall back to SMS. Every single other app, the receiver has to have installed first.

> As ridiculous as it may sound, my kids have actually been left out of social groups in the past because iMessage doesn't (or didn't?) work very well with Android phones

It's unfortunate but not ridiculous. SMS is bad for sharing media and missing a lot of features that make for better conversation. And group texts in SMS are just kind of broken in a lot of different ways, nothing to do with iMessage.

As I said I was going from memory from a class 30 years ago.

Looking at the case again, I see that the dispute was on whether tax should be withheld in the US. The tax treaty between the US and Australia said that the US would not tax the winnings. The winners had filed the appropriate form with the IRS to invoke the treaty and be exempt from tax.

The state lottery commission automatically withholds federal and state taxes, and refused to make an exception for the Australians. The Australians sued and a district court issued an injunction to stop the state from withholding those taxes.

The federal and state governments appealed. The appellate court reversed and removed the injunction. It turns out there is a law that prohibits courts from issuing injunctions to stop tax collection (and withholding counts as collection) so the district court overstepped its jurisdiction. What you are supposed to do if you think a tax is improperly applied is pay it and then seek a refund.
One of the highest confidence outcomes I predict from LLM use in software dev is more use of open protocols. It is going to become difficult to maintain a network if you don't use them.

XMPP isn't dead either. Here's an open source project of an XMPP based Slack - https://prose.org/ (I have no association to this, was amazed how much digging it took me looking for Slack/Discord alternatives to find it.)

The most damage to open communications software probably came from the closed mobile app stores. The barrier to maintaining a working app simultaneously on iOS and Android is high. Almost every iOS game I bought 10 years ago is inaccessible and no longer downloadable. Those barriers are in the process of being torn down too, with or without AI's help.
You see some of this if you go through "entry-level" MOOCs at elite schools, especially in topics like computer science. As a refresher I took MIT's Intro to CS and Algorithms or whatever it was called. I would have been utterly lost had I not already known Python reasonably well.

That's probably less true in some other majors; there likely no real expectation you've taken shop classes for mechanical engineering. On the other hand, you'll maybe also graduate without knowing a lot of the ins and outs of designing and building a piping system.

I really want to dive in with Cue, but one thing that I got burned on when using jsonnet to generate CloudFormation templates years ago was lack of discoverability for newcomers to the repo.

Taking your sample code as an example, someone might look at the myapp deployment definition and ask: “does this deployment get created in the default namespace or does it automatically create a myapp namespace? What’s the default number of replicas? Are there any labels or annotations that get automatically added?” Etc.

On the flip side, there’s potential lack of “greppability.” The user may have found a problem with a deployed resource in, say, the development cluster, and go to grep for some resource-specific string in the repo, only to come up empty because that string is not in the source but rather generated at by the templating system.

To be clear, both of these problems can affect any method of generating config, be it yoke, helm, ksonnet, kustomize, or cue. It’s like a curse of abstraction. The more you make things into nice reusable components, the easier it is for you to build upon, and the harder it is for others to others to jump in and modify.

At least with Cue you get properly typed values and parameter validation built in, which puts it miles ahead of “everything is a string” templating systems like the helm templates the article complains about.
Some people just like shifting manually. It's a preference thing.

I agree that DCTs are great. Modern DCTs are amazing. I don't personally feel that DCTs take away from the driving experience at all.

It does get tiresome when people become snobby about driving stickshift, though.

Fellow professor here, I don't think your approach would work where I teach. I teach in a Polytechnic school (Portugal), which is almost free for the students, so the incentive that they are paying good money does not work.

This semester I'm teaching a web development course (fullstack development), and my policy is that the project must be done on github classroom repositories, and I'll be asking clarification (face to face) on some of the commits. They can use whatever they want (stackoverflow, chatgpt, whatever), but they better know how to explain their commits to me. I don't know if my approach will work in the end, but I surely got their attention.

I'm doing this because it got so bad that, last semester, on my Object Oriented Programming course, even using moodle with the Safe Exam Browser on and an instance of Visual Studio code to try the code, we caught lots of cheaters. How they were doing it? By installing co-pilot plugin. How did we caught them? Some students solve all the exercises in 10 minutes, others had comments that were clearly made by AI, etc. etc. Of some 15 students we caught, only 3 came to us to review the exam.
