I have to comment. That's huge! Way bigger than most UK Victorian 2 up, 2 down terraces. More like the size expected in an older 4 bedroom house if you ignore the extra space the photographer is clearly standing in. Have a random right move link of what I think as typical Victorian worker's terrace: https://www.rightmove.co.uk/property-for-sale/property-62228...

That's slightly smaller than ours probably all in all. But I've seen smaller, like the one up, one down back to backs in Leeds/Woodhouse and many modern flats apartments, are just broom cupboards - but then you look at down town Japan and this feels palacial.

I'm sure most of humanity for most of history have made do with smaller rooms than that. How do you cope in a car?

Sounds like a car might just be bigger... But joking aside, I'm surrounded by glass on all sides in a car. That makes a great deal of difference. I probably wouldn't feel confined in a room that size if I had an entire wall of glass.

In a UK terrace, even given a large bay window, your view will likely be squandered by a large work van, as the terraces seldom have off-street parking.

> Raspberry Pi 3 media center Just read theverge review on how the Pi struggles to play a video full screen, even if resolution is 480p. How are then people using it as a media center?

I've never had these problems with the various media center apps. My Pi 3B+ has been running Kodi for a few months now, and it happily plays 1080p videos at what appears to be smooth 60 FPS. Mind, this is specifically running under Kodi, which is optimized as a media center, and is NOT running also a full desktop environment. Attmepting to do the same in, say, the stripped down Chromium browser was an exercise in fru…

Likewise. While a lightweight desktop on even the 3B+ can be excruciatingly slow, I ws using the 2 as streaming media center for 1080p video without issues. The main thing to look out for is compatible codecs.

There is an official PoE board that fits the pi 3+ which uses a 4 pin header by the ethernet jack to grab power. The pi 4 appears to have the same header. https://www.raspberrypi.org/products/poe-hat/

Seems kludge-y. IMHO, if one is going to do one of these types of embedded systems, then PoE should really be part of the design process from the beginning. They're using the Ethernet on the BCM2711, and Broadcom has sadly deemed PoE not needed I guess. The PoE HAT had a bunch of issues: * https://www.theregister.co.uk/2018/09/11/raspberry_pi_poe_ha...

It is a kludge. PoE is 48V DC, so any converter is gonna look bulky and impractical next to the Pi.

> not typically been used to implement malicious functionality so raspberry pi, in an effort to be more open than say Dell/HP, where you had/have to pay to download drivers, bios and other updates, is _more_ malicious than say apple/google who are competing to create a closed garden with a remote lockout, where nothing is owned, only rented? ya.

I don't own a smartphone/any Apple/Google products, or Dell/HP machines for that matter (not surprising to me that they're bad). My frame of reference is typical PCs, which aren't in the habit of applying vendor lockin with regards to what peripherals you can use - and other SBCs. I don't understand the premise that not applying vendor lockin to a camera module would make SBCs unreasonably expensive. Competing SBCs a…

> I've never seen one which costs "£500".

2006, gumstix with bluetooth was $180, but that was a very small system to dev for. embedded 386 in volumes of 1 were ~£380, CF flash(certified) £80-200. Software was extra, as was the debugging interface, which may or may not be a fancy serial port. Ethernet, RF, all extra. Wifi? naaa.

The arm board, I don't know how much they cost because they were custom made. So hundreds of thousands I suspect.

Then we have the tools that supported it, not exactly kid friendly.

We do have another room, that's slightly larger but it's a bit bleak. And weirdly it's a more fussy room to furnish. The smaller size is better in the winter. The old brick terraces aren't that warm. In large houses people can gravitate to smaller rooms for that reason. Personally I'd like a large room that I could bring the furniture in from the sides. Lucky to even have a house to live in to be honest, so can't rea…

> I wasn't aware of a major homeless problem in Europe.

Homes in the UK can be expensive, so there's a large rental market.

On top of that many people are vulnerably housed - living in emergency temporary accommodation (which may be for many months) or on friend's sofas.

The introduction of the benefit "Universal Credit" has increased homelessness and people who are vulnerably housed. In the UK a landlord can apply for eviction if the tenant hasn't paid for two months. (This is for shorthold tenancy agreements where tenants have most rights - other tenancies have less protection.) There is a minimum wait of 5 weeks before Universal Credit claimants get paid, which pushes some people very close to this limit. The bizarre sanctions regime tips many people over that limit.

This was mentioned in the rpi forum by staff: May I ask whether RPI supports things such as 10 bit video decoding, Dolby Vision and Atmos? Thx. HEVC hardware decode supports 4kp60, 10-bit. Audio output is pretty much unchanged, but the HDMI audio channels now support 8x192kHz bitrates.

Sure, but the video decode IP is a different piece of hardware from the video scaler/compositor. In a typical SoC, you have the GPU and the video decode engines as separate blocks that feed into the video scaler/compositor which then blends, rotates, scales, .. etc the inputs and feeds the final signal to LVDS, HDMI or whatever. Now does it make sense to have your video decoder support 10 bit when your compositor can…

Yeah, that makes sense - you wouldn't want to gimp the system by only doing half a job :)

It is, but in my experience the reliability factor is pretty ugly for the rpis. I'd rather either pay directly for the device designed for it, or just run the software on a machine already on the network. Obviously that doesn't work for everyone.

In my experience, anything other than the Cloud Key is quite unreliable. I have been running it on my Win10 desktop without many issues besides the annoyingly restarting after updating.

I run it as a Docker container on my unRaid server and it's been super stable.

The only issue I have with the Rpi is the microSD lifespan. Of course you can make it read only, but at that point I would pay $10 more to have at least 1GB or less of quality flash memory on it. I've heard microSD will always die at some point. Of course you can also boot from USB too. I'm also waiting for a new rpi zero.

You can get industrial microSD cards for not that much money. Mouser has a couple models with MLC flash for under 20 EUR. E.g. SDSDQAF3-016G-XI

Why not? I'm not very familiarized with this space, but couldn't you just use a low-profile USB flash drive like this [0]? [0] https://www.amazon.com/dp/B01GK9921C/

In theory, yes (but quality varies a lot on them). The point is that adding a proper eMMC would have made the device a lot more "production ready".

It's not for production it's for kids to learn to code on.
