    Raspberry Pi 4

    According to what I'm finding so far, actual Bluetooth 5 features may be non-existent: https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=245492&p=1499926 https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=244386#p1497702 Looks like you can't expect higher speeds, longer range, or any particular benefit at all. I'm not sure if there would be any positive outcome from using a Bluetooth 5 device with RasPi 4, so it may be a very misleading selling point. Seems like with any two Bluetooth devices, one of them will be the weakest link. If it's as bad as claimed, attaching a BT5 USB dongle to the Pi might yield better results. https://www.androidauthority.com/bluetooth-5-speed-range-762369/ Bluetooth 5 can potentially "double" or "quadruple" range, knocking max data rate down to 500 Kbps or 125 Kbps respectively. If you were to use a super-efficient audio codec like Opus, 100 Kbps should be more than enough for podcasts and even streaming music. But when I was researching Bluetooth 5 headphones, I found zero indication of Opus support anywhere, with many of them relying on the old SBC codec, even though Opus or any other codec could be added as an optional extension to A2DP. Here's some discussion. Someone compared RasPi 4 CPU performance to the Intel Core2 Duo T5600, a 2006 dual-core mobile chip with a 34 W TDP. I'm not sure if I buy that, and it's hard to find good direct comparisons right now. Also, a fresh new firmware update has apparently increased performance while reducing operating temperatures. You might be able to get a substantial boost from having a heatsink, metal case, or small fan. I think it's plausible that RasPi 4 could run some TDM missions at a playable (low) framerate, but more research is needed. Now for something more interesting. The user guide for the RasPi 4 possibly makes reference to a variant with 8 GB of RAM. See the heated discussion in the comments. There doesn't seem to be an actual 64 Gb (8 GB) LPDDR4 chip with a 32-bit bus, or something like that. Compare to this new 12 GB LPDDR4X chip from Samsung that has a 64-bit bus. I'm in the "more RAM is best" camp, even if on the face of it, it seems absurd to have that amount attached to this device. Raspbian or other desktop-focused OSes should be able to take advantage of the full amount, caching stuff that would otherwise be loaded from a slow microSD card (unless you are booting from an external SSD). Maybe we will see a $75 RasPi 4 variant in 2020 with 8 GB of RAM and fixed USB-C charging implementation. So if you were on the fence about this thing, you could kick the can down the road and see what they do next year. At the same time, 4 GB is going to be enough for a lot of use cases, and the USB-C problem is not that serious.

    Raspberry Pi 4

    My initial thoughts on the USB-C thing were pretty harsh, but thinking about it more I don't care as much. A bunch of cables do work (see link), the ones that have the broken feature tend to be more expensive, and I would probably dedicate a cable/power supply to the RasPi 24/7 and not use it for anything else. Looks like TDM would still require some leg work to compile on ARM, but it's much less of a fool's errand now: OpenGL ES 2.0 -> OpenGL ES 3.0 1 GB RAM -> 4 GB RAM (shared with GPU in both cases) 4x Cortex-A53 -> 4x Cortex-A72 23.5 MB/s read performance -> 45.7 MB/s (microSD) or higher (SSD) 27.8 FPS -> 41.4 FPS (720p OpenArena) OpenArena is id Tech 3 whereas TDM is id Tech 4. But we can see a definitive performance uplift and that extra RAM would be crucial for TDM. The Raspberry Pi 4 might be more powerful than other systems users have tried to run it on. If not, Raspberry Pi 5 will probably seal the deal when that is released 2-3 years from now. Official support for TDM on RasPi 4 would be pretty neat, and might be a good way to attract new members if we can spread the word on RasPi-oriented sites.

    Raspberry Pi 4

    https://en.wikipedia.org/wiki/Raspberry_Pi https://www.raspberrypi.org/products/raspberry-pi-4-model-b/ https://www.raspberrypi.org/products/raspberry-pi-4-model-b/specifications/ https://www.tomshardware.com/reviews/raspberry-pi-4-b,6193.html https://www.anandtech.com/show/14581/raspberry-pi-4-launched-quad-cortex-a72-project-board-for-35-dollars https://www.raspberrypi.org/magpi-issues/MagPi83.pdf Major improvements across the "board". The quad-core Cortex-A72 with other improvements is anywhere from 25% to 300% faster than the A53 used in the Raspberry Pi 3 . No eMMC but an SSD could be used with one of the two new USB 3 ports (booting from USB or Ethernet not supported at launch, should be ready within weeks). There are three RAM options: 1 GB ($35), 2 GB ($45), 4 GB ($55). The RAM is now LPDDR4 instead of LPDDR2. The 2 GB option is a bit unnecessary IMO and seems to be the least popular, as it's the model least likely to be sold out online (as far as I can tell). Ethernet speed can actually hit close to 1 Gbps (943 Mbps), up from 237 Mbps. There is Bluetooth 5.0 support but I haven't seen any testing related to that (I would love to use it for longer range audio transmission to BT 5.0 headphones). RasPi 3 cases are incompatible due to some port shuffling. There are now two micro-HDMI ports instead of one full size HDMI, so you probably need a new cable. The device can output to two 4K displays at 30 FPS, or one 4K display at 60 FPS (presumably two 1080p displays @ 60+ FPS, and so on). Although the new GPU has 4K@60Hz H.265 decode support, actually streaming 4K and even lower resolutions on Raspbian had issues in testing, that will hopefully be resolved with updates soon. LibreELEC developers have been working with the Pi Foundation for months to support the Pi 4, and have an alpha version out. Power draw and heat are up. You'll probably want a FLIRC case or something that can provide cooling. Power is now provided using a USB Type-C cable. Due to a screw up by the Raspberry Pi Foundation, some USB-C cables don't work. But the ones that do work should be the cheapest. Can it run TDM? The CPU and GPU are much better and the potentially quadrupled RAM could be a big help. The 4 GB version can be a legitimate desktop replacement for many users, albeit with some quirks.

    The AMD 3rd Gen Ryzen Deep Dive Review: 3700X and 3900X Raising The Bar The AMD Radeon RX 5700 XT & RX 5700 Review: Navi Renews Competition in the Midrange Market AMD did a last minute price drop to respond to Nvidia's Super 20X0 GPUs.
  6. Use GOG. Or Steam only if the games are DRM-free. Reject titles that require online activation, always online functionality, etc. Unless they are multiplayer and you don't mind accepting that the game could be killed. You can also sail the high seas. Use fully loaded Kodi too.

    Cyberpunk 2077

    Looks pretty great. If I get it, it will be on GOG. But I need a new computer first.
  8. The real problem with Valve is called Epic Games Store. You know, the one that is paying out millions to crowdfunded indie titles to transform them into exclusives (enough to cover all backer copies being refunded). A platform where user reviews are not central and can be completely disabled by the publisher. Steam has to match or nearly match the 88% cut to stop the bleeding. They can focus on making games after they solve this problem.

  10. Left: Clock is nice and bright, text harder to read, URL is jarring. Right: Clock aspect ratio is squashed, should be circular, but the text is easier to read and there is no URL over the logo. Clock is dim.
  11. Welp, here it is: http://spaceengine.org/news/blog190604/ https://store.steampowered.com/app/314650/SpaceEngine/ June 11 launch. If I'm looking at it right, it could be free except for the SpaceEngine PRO DLC, which upgrades the license and has features that not many casual users would need. Kind of like how Google Earth used to have 1-2 paid versions for commercial use.
  12. I think it happens on larger threads. The one I remember it happening to me on (forum notifications, not email) is the "So, what are you working on right now?" thread which has 318 pages spanning a decade.
  13. Good work. I think you've found the next 40 uploads for your channel. Now if we can only use machine learning to enhance the audio (more prominent hiss/artifacts in T1 briefings than T2 IIRC).
  14. 7.9 GB? Might as well kick it past DVD-9 straight to 25 GB Blu-ray and throw all the current FMs on there.
  15. UFOs is a generic term. Unidentified alien spacecraft != UFOs != E.B.E.
