I think only in certain cinema rigs. See DJI's products eg https://store.dji.com/product/dji-focus-pro-lidar


And just mentioning for people unfamiliar with this stuff, that's not a camera and not even an accessory for a camera. That's an accessory for an accessory. :D

It's a LiDAR that follows a subject and gets distance measurements, and then sends them to an additional accessory which is typically used to control focus in cinema cameras. That second accessory has a motor and is attached to a cinema lens that has certain threading or grooves where the accessory can grip and change the focus.

In cinema, the camera operator (usually) only moves the camera, but not the focus. For that, there's a 'focus puller'. A person who finely operates the focus, sometimes at a certain distance, using some sort of specialized control.


I wonder how much it's possible to recreate some of the old magic.

I'm sure it's impossible, but what if it's not?


Yes, the government pays (lots of money) for Claude Gov that they use on their networks.

In my experience they very much do not want to be told what they can and can not do with the things they purchase. I’m surprised the deal got done at all with these restrictions in place.


Purchasing a service is different from purchasing the company, though.

As such I agree with the surprise at the deal getting done at all.


This operating system sounds very interesting! How active is the development? I would imagine it's the type of thing that eventually gets "complete"


I've been gainfully employed for well over a decade working on it and it's been around in one form or another for over 40 years. We're constantly improving performance and capabilities, adding support for more hardware, supporting the specific needs of our customers etc... Just like any modern operating system, it's never really "complete". STOP is a "security from the ground up" OS, where security isn't just a first-order priority, it's the entire point, typically used in/as multilevel security solutions.


Are there any documents we can use to learn more about it? What does it look like to the user? Is it intended to be embedded?


There's a link in my profile to the company products page for my group, which includes a link to the STOP OS page. There used to be additional documents you could download from those pages, but it looks like they're not working any more.

The short version is that it implements three different MAC (mandatory access control) policies (RBAC, Bell-LaPadula, Biba) and the standard *nix DAC policies. It's designed for safely handling/moving data on/between multiple classification levels. (See the SCOMP section in [0] for history). From a user perspective, it's very similar to Linux, with a largely Linux-like ABI and similar user interfaces, including a full X/xfce GUI environment if you want, though most actual deployments tend to run headless with only required software loaded. It runs on both small embedded boards and large enterprise servers and a bunch in between.

The data diode one reminds me of a null-modem cable I once did where I forked the TX line to a second DB-25 so that a server could eavesdrop the data coming from the PABX to the call tracking box. The server would then push it to all stations connected to a socket, where a Java applet would display the proper greeting the support agent would use when the call came in.

I guess I’m dating myself quite a bit.


I'm extremely jealous of Cloudflare getting the trademark for The Network is the Computer (https://blog.cloudflare.com/the-network-is-the-computer/)


At our company (almost entirely engineers) we're pretty near 100% thin client usage. It's nice to be able to "download more RAM" for a big analysis job and not have to go try to buy a new system or something.

I also travel a lot, and it's great to have all of my applications and data right where I left them from any desk in any office


Nice, what thin clients are you using? After Sun Ray, I tried an Axel one, but never really found a use case for it.


Originally we used PCoIP server software and various Zero Clients (they all run the same software). Their video performance is really great, but we found it very difficult to get support for basically anything else (USB, licensing, host OS, etc).

One thing lead to another and now we're building our own server software, thin client OS (no hardware yet, we load our image on COTS x86 devices), and public VDI cloud.


The Sun Ray is a strong inspiration for building https://warpstations.com (currently in closed beta).

The main challenge has been building a modern remote desktop protocol that achieves high performance but without requiring GPUs for each user and works on Linux. VNC is really showing its age, and X forwarding isn't really usable over the Internet. We are also using Yubikeys instead of smart cards, though I'm looking forward to testing some of the FIDO2 cards that are on the market.

One of our colleagues said something that really resonated with me "When you're working using our system it should feel like you're sitting down at a personal supercomputer". There are always more features to build, but the basic vision of being able to sit down at any desk with our Warpbox and connect to your virtual desktop within a few seconds is a really nice workflow.


I may be misunderstanding, but I'm not sure I want a "remote desktop" where every process runs on the remote.

I want the original promise of X, where I choose where apps run and they are displayed locally:

• Run CAD circuit layout app on Pro server.

• Run Adobe Premiere on GPU server.

• Run distributed `make` on build cluster.

And of course, I want to be billed in resource-seconds, not per hour of a host made available to me.


"and X forwarding isn't really usable over the Internet."

Well, maybe not directly so, but NX (or rather X2Go) over ssh or VPN was working fine for me some ten years ago. Before that I happily used Sun Rays, but maintaining the Sun Ray server software was tedious after Oracle gave up on it.


This looks really cool. I didn't quite understand what the product did on the website, but once I read your comment, I got it.

Is there a short trial period before I pay? I didn't see it on the website. If it really does feel like real time usage like GeForce Now with gaming, then that is seriously cool.


Thank you for the feedback about the website. I'd love to hear more of your thoughts about what was unclear or how we could improve if you can email me (email in profile).

I'd be glad to set you up with credits to run the system through its paces. Right now our most valuable payment is feedback


Done!


Is there public information available about why Netflix uses Linux as opposed to FreeBSD for those pieces of infrastructure?


Netflix runs Java and the Oracle JVM runs on Linux but not FreeBSD.

I have no information, but there aren't very many dots to connect here.


Not necessarily. It was probably a good idea in Jerry Yang's case, for instance


Time will tell.


> Not that have knowledge of royalty proportionality, but it also seems unfair to have royalty costs dwarf any other business costs.

Why? Their business model is to take other people's work and distribute it to subscribers.

It seems to me that acquisition of the actual product should be the majority of their cost.


Excessiveness in the injection of normative notions to a market seems like a bad idea.

In any case, the content is only an aspect of the value, and without the value add many services would be rather useless. If the cost of content dwarfs the use's value add, something with potential becomes something untenable.

I mean without streaming, multiple platform support, browsing/searching, etc., what would Netflix be? The delivery method and interface themselves have value, and it's not insignificant at all.

Remember the purpose of copyright isn't to give creators rights. It's to drag as much out of them for as little cost as possible for the sake of the enrichment of society as a whole.


Apple's store does the same stuff and takes a 30% cut. They aren't directly comparable, but they are charging the 30% for similar services (streaming/downloading, platform support, browsing/discovery, and they add payment and distribution on top of that...)
