Given Broadcom's connections to the project, it's almost a surprise they didn't have some kind of Broadcom option for WiFi/BT earlier. Must have stung at Broadcom to be powering the most popular hobbyist ARM Linux board, but almost every one using WiFi powered by Realtek,Ralink,etc.

Broadcom's "connection" to the project often seems circumstantial, like the Pi project is a blip on nobody's radar. Several of their engineers used to work at Broadcom and they've been under NDA lock and key, bending over backwards to help people progress on things that they can't officially talk about by leaving the least subtle clues ever so that they can move the process forward. The GPU/camera integration in part…

I think even the founder Eben Upton works at Broadcom too.

I strongly disagree. I have zero interest in today's bloated AAA games. Simple games like Tetris, Mario + romhacks, or Civ II have given me collectively more fun that I would ever have playing some insipid shooter or uninspired pay2win fantasy game. I wouldn't trade them for any of today's games, which I consider severely flawed in many ways.

Sturgeon's law applies. We only play the 10% (or less) of old games that are good. There are good new games, too.

I don't doubt it. I only say that the percentage of good older games is at least equivalent, if not greater, than the percentage of good newer games.

Is a ceramic wifi antenna's range comparable to that of a regular PCB antenna?

Usually slightly better, as it can be a 3D structure.

More accurately, better if considering antennas of equal footprint area, however chip antennas are usually designed to be very small (like this one) as the extra cost is only justified when space is at a premium.

In my experience in practice a good-sized PCB antenna beats tiny ceramic antennas. I would expect the radio performance of this Pi to be pretty poor, though better than using one of those tiny USB adapters (which also typically use even smaller ceramic antennas with really awful ground reference when used in a Pi as they are designed for use with laptops).

Also, another reason for their smaller size is that ceramics can have very high dielectric constant which reduces the size of the antenna.

As far as i'm aware those are all still proposed regulations and not in effect yet.

I think TP-Link is already shipping with a firmware in lockdown http://ml.ninux.org/pipermail/battlemesh/2016-February/00437...

But that's just because TP-Link wanted to, not because of any FCC rule (at least, that's what an earlier discussion here on HN about that router said)

The Raspberry Pi website says they're unlikely to have a new version in the next few years. Do they have FCC now? Maybe they just want to add on the radio modules. From the FAQ: > there are no immediate plans to release any more new models. A further new model may be released in 2-3 years, but this is not a firm schedule. https://www.raspberrypi.org/help/faqs/#generalFuture

They said that, then they Released the Pi Zero.

That statement was in Feb 2015 after the pi2... the PiZero was Release Nov 2015....

> So network speeds were limited to USB 2 speeds Given that USB 2.0 is 480Mb/s, and Ethernet is 100Mb/s, there is no bottleneck when using the Pi's Ethernet port. I really wish this myth that "Pi Ethernet is slower than dialup because USB" would just die. Of course, like everyone else I'd love to see a new version of the Pi with Gigabit Ethernet directly connected to the system bus, and USB 3.0 while we're at it. But…

>Pi Ethernet is slower than dialup because USB I can't find any info to say which bus the MMC reader is connected to, but I know if you use a USB drive as well as the built in ethernet port, speed will suffer.

None of them. The SD card connects directly to the CPU.

Are you sure that's the antenna? It looks more like it'd be a balun. It even has what looks like a feed line going to the keepout that's right next to it. I feel like the one in the picture is missing the actual antenna.

balun (white ceramic part with brown rectangle marking) appears to be on the other side between the chip and via to the antenna http://www.digikey.com/catalog/en/partgroup/2-45ghz-balun/52... or similar

Oh, it's on top (which they totally said). I'm not a smart man.

I must be the only one disappointed with old-school games. I was super excited to set up a retropie, after 20 minutes playing the nostalgia wore off quickly. Anyone else find the same?

I have a collection of old C64 games flying around on some of my external drives. Never got to play them. But one day I remembered Deuteros. An old Amiga game. I made it through the whole game back then without knowing English at all. I was so proud back then, I had to pick it up. I couldn't believe it but I played it through all the way again. I really can't say what it was exactly but I guess it was the flashback.…

I totally remember Deuteros. It was riveting. I remember adding more and more stations and bases, I thought I had the game down, and then after deploying a certain number of stations, I triggered a reaction from the aliens and little by little, they started destroying all my empire. I was never able to beat that game.

But what a memory.
