I realize "Plasma" is the name of the KDE presentation layer across all platforms, but it's mildly awkward to see in this context considering plasma TVs have only been a dead technology for six years or so: https://en.wikipedia.org/wiki/Plasma_display
Re:Plasma Bigscreen by safety1st on Friday September 16, 2022 @07:11AM (#32864575)
Frankly it's disappointing that most of the comments on HN so far have been focused on the "marketing" and the website. The FAQ states that this project is still in very early stages and not yet intended for use as a daily driver. So if you actually read the website, it's clear why it's not consumer grade. I would much rather they focus on developing than marketing at this stage.

The basic thing going on here is simply that the KDE guys are working on a 10' experience and that's great, there is no good 10' experience today on Linux. Unless you count Steam Big Picture mode I guess? But a desktop environment which knows what to do about 10' would be really exciting.

Edit: for anyone who's interested, this appears to be the repo for the Bigscreen project: https://invent.kde.org/plasma/plasma-bigscreen/activity

The distro images on the website may be out of date.

Re:Plasma Bigscreen by kwhitefoot on Friday September 16, 2022 @08:00AM (#32864921)
The splash screen makes it look like this is something you can simply install on a television of your choice.

It is perfectly reasonable to criticise the marketing when it gets in the way of the message. Having to find and read the FAQ to discover that it is basically just a prototype desktop environment for existing distros is a bit silly.

Re:Plasma Bigscreen by sbarre on Friday September 16, 2022 @08:21AM (#32865135)
I will admit that at first glance I thought this was a firmware hack for TVs, and I immediately started digging around the site to try to find a list of compatible TVs...

Once I found out what it was, it was still quite cool and I am curious to follow development, but I agree the site design/layout/copy is confusing at best, misleading at worst.

Re:Plasma Bigscreen by Lammy on Friday September 16, 2022 @08:32AM (#32865254)
> I would much rather they focus on developing than marketing at this stage.

Totally reasonable to feel this way, but personally I think naming is so important that it transcends any technical merit a project might have.

For my own projects, I never write a single line of code until I come up with a name I truly love. Some times it takes weeks, but then the project has an identity which keeps me motivated over the long term and actually inspires my technical choices of what to build.

Compare to the “Yet Another” naming scheme which (to me) feels like a preemptive apology for a project’s mere existence: https://en.wikipedia.org/wiki/Yet_another

Or it's a strong signal toward the creators that their clever idea for naming was only clever in their heads and nowhere else?

I too got confused and was wondering "is this a project to revive old plasma TVs somehow?".

Re:Plasma Bigscreen by LoganDark on Saturday September 17, 2022 @12:12AM (#32874706)
The marketing screenshots aren't too attractive honestly. It seriously seems to be lacking in consistent margins and padding. Look at the menu bar for example-- those icons are far too large for the space they fill. They look super cramped.

This is, somehow, typical in most Linux software I've used. They just don't care. :/

What about Xbmc/Kodi? Works great on a raspberry pi hooked up to my TV... Has been doing that since the early 2000's when it ran on my brothers Xbox (original) but that was pre-Linux.

Edit: spelling

Here's a link with a lot more information. The big news today is that the UI component for Bigscreen has just gone live as a part of the KDE 5.26 beta, which is relatively straightforward to install on any Linux distro (or image to a USB stick): https://kde.org/announcements/plasma/5/5.25.90/

Maybe the post's main link should be changed to this one? That Bigscreen website seems to be confusing and out of date.

https://en.wikipedia.org/wiki/10-foot_user_interface

There are 10' experiences for Linux (Kodi, Plex, and Steam Big Picture are what I know of), but these aren't integrated into the desktop, they are focused on TV/movies and gaming respectively, so KDE focusing on this problem is something new.

Although I think your point is correct.

Re:Plasma Bigscreen by LoganDark on Saturday September 17, 2022 @12:14AM (#32874716)
I'd say 10' is within the margin of error considering how many significant figures they gave in their estimate.
Re:Plasma Bigscreen by chasil on Friday September 16, 2022 @07:52AM (#32864862)
Is this essentially Lineage for smart TVs?

Can the vendor OS be wiped from these devices?

If so, is there a list?

Re:Plasma Bigscreen by safety1st on Friday September 16, 2022 @08:03AM (#32864958)
I think that's close to, or part of, their vision: https://plasma-bigscreen.org/vision/

What they have in the Downloads section now is basically a variety of distro images which you can run on a Pi, or a device that supports pmOS, etc. There's a long way to go before you could buy any random smart TV and flash this onto it. Though maybe less long if you have a smart TV with an embedded Pi which might be a thing these days?

Re:Plasma Bigscreen by donatj on Friday September 16, 2022 @12:22AM (#32862041)

I'm pretty sure you'll only ever be able to have either an open source TV or all the streaming apps. No reason for Amazon, Netflix, YouTube, or the others to support this platform.
Re:Plasma Bigscreen by ognarb on Friday September 16, 2022 @05:18AM (#32863939)
The biggest hurdle is the DRM. Plasma Bigscreen ship with it's own browser but you still need the proprietary blob for the DRM running on an ARM device instead of the usual one for intel/amd. Making things worse, even on intel/amd the video quality is often limited to 1080p on Linux.
Re:Plasma Bigscreen by ChuckNorris89 on Friday September 16, 2022 @05:41AM (#32864098)
Funny, since DRM is never an issue if you play pirated content. Arrgh maties!

But ironically, DRM is only a huge annoyance for paying law abiding customers.

Did you pay Ubisoft $50 10 years ago for Assassin's Creed 2, am amazing game? Great, because now you can go f*ck yourself instead of playing the game since Ubisoft took the server running the DRM for that game offline. Did you pirate the game? Great, because now you can play it for free indefinitely.

And there are countless horror stories of paying customer bases getting shafted on the products they (used to) own via DRM.

Re:Plasma Bigscreen by jbay808 on Friday September 16, 2022 @06:44AM (#32864419)
I purchased DUNE on YouTube. Turns out even after paying full price, the image quality is limited to 480P unless you watch via a smart TV.

To prevent piracy, or something.

Re:Plasma Bigscreen by matheusmoreira on Friday September 16, 2022 @08:32AM (#32865247)
Even worse is the fact that they sacrifice quality for bandwidth. Even if you manage to meet all their silly DRM requirements, you get poor quality video that's high definition in name only. There are titles in Netflix that have compression artifacts in 90% black frames.

Meanwhile pirates enjoy Blu-Ray rips encoded by people known for taking pride in providing the highest possible quality.

Re:Plasma Bigscreen by ChuckNorris89 on Friday September 16, 2022 @06:51AM (#32864450)
Are you watching YouTube on Linux by any chance? AFAIK modern versions of chrome and FF should not have this issue even on Linux but I could be wrong as I'm out of the loop on modern DRM.

Re:Plasma Bigscreen by jl6 on Friday September 16, 2022 @09:54AM (#32866068)
Fortunately since 2015 it has been legal to circumvent DRM for games that have had their single-player mode rendered inoperable by the decommissioning of an activation server:

https://copyright.gov/1201/2015/fedreg-publicinspectionFR.pd...

Yes, it still sucks when publishers make their customers jump through hoops like this, potentially exposing them to malware if the necessary DRM circumvention software comes from a dubious source.

Re:Plasma Bigscreen by comboy on Friday September 16, 2022 @04:26AM (#32863589)
Seriously? Well not connecting them to the internet works less and less, Amazon is rolling out their 900Mhz mesh with echo devices and there's LTE-M, NB-IoT and such.

The idea of not letting a device connect to the Internet is slowly becoming a thing of the past unless you live in a faraday cage (which is becoming more and more tempting). Oh, correction, thanks to mesh networks like that of Alexa living in a Faraday cage is not actually enough if at least one device is connected. Yay.

Re:Plasma Bigscreen by lrvick on Saturday September 17, 2022 @03:22PM (#32880552)

Re:Plasma Bigscreen by TickleSteve on Friday September 16, 2022 @08:34AM (#32865266)
Even with a mesh, devices still have to be authorised to get access. Just don't do that.

The more difficult option is if they come with cellular modems built-in, thus bypassing any of your infrastructure (which needs authorisation). That of course is technically possible, tho probably commercially unacceptable (modems cost ~15 to 20 dollars in bulk which is significant at smart-tv scales, not counting the data cost).

Re:Plasma Bigscreen by lrvick on Saturday September 17, 2022 @03:25PM (#32880574)
More expensive IoT items like modern cars ship with factory activated cellular modem based tracking. Your options today are to buy older base model vehicles or learn to use a screwdriver and a soldering iron.

> Even with a mesh, devices still have to be authorised to get access. Just don't do that.

Nope, the whole point of Amazon Sidewalk is that it "just works." I don't think there's even a way to know what devices are connected, let alone any kind of authorization.

Re:Plasma Bigscreen by sangnoir on Friday September 16, 2022 @03:10PM (#32870667)
LG WebOS TVs are capable of image + sound fingerprinting at OS level! Not only can they identify what you're watching, it's accurate enough to tell which scene you on and provide "handy" information overlays.

The name is generally really unfortunate, and I wish they would switch back to KDE for the Desktop Environment (and call the framework Klibs or KDElibs or something).

Many people have positive associations with KDE, but associate Plasma with bloaty QML based desktop widgets from the KDE4 era. If they even associate it with KDE, and not with plasma TVs or blood plasma.

People who know KDE hardly need marketing - they already know what is what and what they want. So they could name it whatever way, I only care about how well does that name integrate in the whole namespace of Linux apps/libs/packages. At the same time, for non-techies or people coming from other OSes Plasma automatically sounds cool, doesn't it?

Nevertheless, as for what I personally feel, I agree - I like KDE better.

Re:Plasma Bigscreen by irjustin on Thursday September 15, 2022 @11:25PM (#32861708)
Admittedly i thought this as well. was hoping for a new plasma tech! Not that i think it's better, just nostalgia - it was the first 'new gen' tv I owned back in 2007. Heavy but well worth it at the time.
Re:Plasma Bigscreen by greyhair on Friday September 16, 2022 @08:32AM (#32865249)
Still running my Panasonic 50" Plasma from that era. So heavy. And yes they are power hogs, but in reality, ours really isn't on that often. Three, maybe four hours a week, on average.

But oh, the picture quality back then, compared to LCDs and rear projection. No comparison, and even today, it holds up well.

this is about justification. The current thing works fine but I would like the new expensive thing. I cannot justify expense of replacing working thing, but if it would die, then it's justified expense.

it isn't about that it's more economical purchase when it dies, but I even saw people breaking stuff just so they "had to" buy new thing that they want.

Re:Plasma Bigscreen by saaaaaam on Friday September 16, 2022 @05:01AM (#32863826)
Expense doesn’t always mean purely financial. There is an environmental cost to buying something new as well, and a social cost in supporting the manufacture of electronics that may have less than perfect supply chain ethical standards.

Re:Plasma Bigscreen by greyhair on Friday September 16, 2022 @08:38AM (#32865305)
Plasma did have an issue with 'burn in' on static images. If you did a lot of gaming on them, you could see it. Same with banners on news programming.

If you watch a lot of movies, it isn't an issue. Plus, the TVs came with a 'burn in' reduction program that you could run a couple times a year, but that operated by sweeping an intense white bar across the screen, so you were effectively 'wearing' the pixels down to a similar level to reduce the obvious burn in. If you ran that cycle to often, it would kill the maximum brightness.

Re:Plasma Bigscreen by ChuckNorris89 on Friday September 16, 2022 @05:52AM (#32864162)

Re:Plasma Bigscreen by eptcyka on Friday September 16, 2022 @04:11AM (#32863478)
OLEDs have very good blacks, but as soon as a pixel needs to emit any light at all, it will be significantly brighter than what a regular IPS pixel can emit at it's lowest brightness.
Re:Plasma Bigscreen by jaywalk on Friday September 16, 2022 @09:00AM (#32865506)
LCD with full-array local dimming can get really close. It also gets much brighter than OLED. It's a much tougher decision than it used to be.
Re:Plasma Bigscreen by bzzzt on Friday September 16, 2022 @04:31AM (#32863620)
Also depends on the TV you upgrade to: replacing a 50" plasma with an 84" LCD will do nothing to decrease your energy usage.

While plasma uses a bit more energy than LCD it's not that big of a deal (especially if you've got one of the last gen plasma panels) if you don't use it as some sort of moving wallpaper but just turn it off when not in use.

Re:Plasma Bigscreen by mrpopo on Friday September 16, 2022 @05:30AM (#32864019)

Re:Plasma Bigscreen by dTal on Friday September 16, 2022 @06:35AM (#32864369)
On the contrary - "Plasma" is one the best branding efforts in the open source ecosystem so far.

It's not really confusing or hard to search for if you know that "Plasma" is a KDE product - for instance, Plasma Bigscreen is the first Google result for "kde plasma tv" and "kde tv". It's 8 years old, it covers several different products with a similar look and feel, and it sounds as cool as it looks.

Big brands don't have an issue with using common words for product lines (like "surface" and "pixel"), and I don't see why open source should cede that ground.
