Go fourth and multi-Pi: Raspberry Pi 4 lands today with quad 1.5GHz Arm Cortex-A72 CPU cores, up to 4GB RAM...

Re: DSI display @4K ?

HDMI only. The DSI is as before.

Re: Still a PoE hat?

Yup, that's basically the story of Raspberry Pi, doesn't matter what we do, someone always wants something else, AND ITS OUR FAULT.

Re: Good stuff

USB3-ethernet adapter should do the trick. Putting two on the board would be expensive, and a cost passed on to all users despite it being a tiny use use. Probably isn't even room.)

James Hughes 1

Re: Still no damn onboard flash

SD cards are still the best way for the 'desktop' Pi, cheap and easy to use. And yes, we are entirely aware of lifetime issues, which you can mitigate hugely by avoiding writing to them unless you really need to (ie logs to tmpfs etc). Some people have had Pi's running for multiple years with no SD card issues.

The cost of adding EMMC would be a real problem - margins on devices like this are small - we don't want to make them even smaller.

If you want industrial, use the compute module, which has EMMC. (No Pi4 version yet).

That said, there is some flash on the Pi4! Not a huge amount, but it contains the bootloader. In the long time, it MIGHT be possible to leverage that, but that is subject to change.

Cannot comment on the Google stuff, we are not Google.

Re: Worst product launch ever!

I can weld you up a stand in the garage, proper metal etc. £999. It'll be massively overpriced though. I could even put a magnet in it for keeping paperclips safe.

Re: victims of own success

Your point is obscure - what are you talking about?

James Hughes 1

Re: Upton reckons that the 2GB version will be the most popular

In our testing, for general desktop use, the 2GB was fine. Big compiles (kernel etc) would benefit from 4GB.

Re: Ethernet

Er, bollocks. Forced to eat own dog food. The ethernet is a native interface on the SoC, it's the USB3 stuff that is on PCIe. Note to self, think before posting.

That said, the GiGE is GigE, and not via USB2.

James Hughes 1

Re: Pi-top

PiTOP were in the office Friday, so they are aware of the change, and presumably have things in hand.

James Hughes 1

As above, read the specs. Yes, it will make quite a good NAS, the networking is full GigE, and the USB3 means attached drives are very fast.

James Hughes 1

Re: Ethernet

No, which had you actually read the specs, would have been obvious. Its on a PCIe bus, and gets very close to theoretical max (1Gbs) in testing.

Re: Sata

USB and PXE boot is on the list of stuff to do. Won't be long. WIth the new EEPROM based bootloader, this sort of thing is much easier to implement.

James Hughes 1

Re: Gone is the full-sized HDMI type A connector,

There simply isn't room on the PI4 for two full size connectors, so it had to be done.

I think the Zero is mini-hdmi....

Re: Palpatine

Just install a VM on WIn10 and run some flavour on Linux. Or just run native Linux.

It just works, unlike Win10.

It's not just Win10 or Mac any more.

Musk loves his Starlink sat constellation – but astroboffins are less than dazzled by them

James Hughes 1

And that already exists. This launch was licenced, and that licence included a large section on the deorbit requriements, as do most other launches nowdays.

Asd it happens, even dead, these satellites will deorbit within 5 years due to atmospheric drag. If they are not dead they can be deorbited much more quickly as they have on board SEP thrusters.

James Hughes 1

Re: Debunked?

For the system to work well they need to know where all the satelite are at all times...

James Hughes 1

Re: Far Side of the Moon

A little Google goes a long way. These are LEO satellites, and the licence to launch them also included extensive requirements on deorbiting. And beause they are LEO, atmospheric drag will bring them down quickly upon request, and within 5 years I belevie if they are completely dead and cannot deorbit themselves.

Israeli Moon probe crashes at the last minute but SpaceX scores with Falcon Heavy launch

James Hughes 1

Re: Better than the Space Shuttle,

No one want to duplicate the Space Shuttles capabilites, because those capbilities are not useful any more. SpaceX have the Dragon2, which will do most of what the SS did at the end of its life (deliver people to the ISS), which is exactly what it was designed to do. The dragon 1 also outperforms the other cargo capsules in that it can return a decent mass from the ISS. The SpaceX reusable system is massively cheaper than the SS, but does an awful lot.

And of course. SpaceX have Starship, which will outdo the SS if it works.

Never seen so much wanky my camera is better than yours bollocks in one thread.

The best camera is the one you have on you when you need to take a picture.

(And yes, I do own a DSLR and a smartphone, and was also the brcm project lead for the camera system on the 808 pureview)

Raspberry Pi Foundation says its final farewells to 40nm with release of Compute Module 3+

James Hughes 1

Always odd when a thumbs down appears on a factual post. Got to wonder what it's for.

James Hughes 1

It's a minor point, but it's Raspberry Pi (Trading) that does all the development (HW and SW) of Pi's and sells them. The Raspberry Pi Foundation is the educational side. RP(T) is a wholely owned subsidiary of the RPF but is quite independent in its day to day running. Now also in a different buildings after the Station road office was flagged up for demolition.

That site is great - fun to watch the ground vehicles rushing around all over the place - can even see where they have been already!

Amazon's homegrown 2.3GHz 64-bit Graviton processor was very nearly an AMD Arm CPU

James Hughes 1

Most odd

Those performance figures do not add up at all. I would expect a A72 at 2.3G to be at least 3-4 times as fast as the A53 at 1.4G on the Pi3B+. It should be about twice as fast just from the architecture upgrade, then add on the extra clocking.

As as for the website comparison - what utter bollocks. That more related to memory, and networking that the CPU speed.

Re: Horses for courses

What DaveK said. Laptop, docking station, a few extra monitors, keybopard mouse (because laptop trackpads and keyboards are horrid). Sits on desk at work, bring it home every day, but don; tuse it unless I HAVE to, makes it easy to work from home. Runs windows but most of the real work done in Linux in virtual box. Actually at home right now typing this, simply plugged laptop in to monitor, now in exactly the same environment I was yesterday when I left work. Laptops just work (mostly)

I've tried doing work stuff on a tablet, admittedly a small cheap Samsung, horrible. For general net stuff, absolutely fine. Not for work.

A new Raspberry Pi takes a bow with all of the speed but less of the RAM

James Hughes 1

Re: USB-C port

Also, USB-C connectors are still surprisingly expensive.

James Hughes 1

Cost, pure and simple.

As for the other requests, not possible with the current SoC. As the launch article from the boss said, this will be the last with this era silicon - we've reached the limits.

Re: the leader becomes the follower

Difficult to see how we can be following something that's based on a form factor we originally produced 6 years ago, and uses two thirds of our naming scheme.

Out in the Fens in a pretty small village, but our broadband is pretty good (75Mbits/s download or something ADSL), but the mobile phone reception is non-existent. Whatever provider, so Uswitch are not going to make much money from us.

Raspberry Pi fans up in arms as Mathematica disappears from Raspbian downloads

James Hughes 1

Re: 300 baud!? You were lucky...

To answer the quesions above, it was included in the download becuase that what our agreement with Wolfram said.

As for the percentage of the download taken up by it, over 30% of the compressed file.

James Hughes 1

It's not just the download time. When doing an update it can take ages to install, so much so that people have thought the device had locked up.

If you add up all the extra 700MB over all the Raspbian downloads from the last 5 years, (100 million? Dunno, might be worthwhile finding out) that adds up to, er, quite a lot of wasted bandwidth.

James Hughes 1

TBH, there has't been that much grumbling. Engineering preference is to have it in the repos rather than installed by default, as it's a huge chunk of the image that a large percentage of users don't need. As a user of Raspbian, but non-user of Mathematica, if you don't remove it, then when an update appears its takes a load of time to download and install it.

Having it in the repo means those that want it can download it. Those that don't save 700MB of bandwidth.

Re: Flashback

Unfortunately its not easy to identify the problem boards, the chips don't have much in the way of ID. Keep an eye out on the blog over the next couple of days - more detailed information to be published soon.

Not sure about the channel - certainly the next production run will have the problem fixed, IIRC it's delayed until the fix is finalised.

Re: Works on my switch

Power over Wifi is in the Pi4

James Hughes 1

Re: not skookum

The MPG2 thing is a PITA. Unfortunately there are still two regions where the licence is required, and since we do not region encode the Pi we cannot guarantee that any Pi will not be used in those regions. We would dearly love to get rid of the whole thing - it costs us more than we make back, to run the licencing system.

James Hughes 1

Re: Works on my switch

I belevie it was a bit more involved than that, but in future we will be much more thorough. Once bitten etc

James Hughes 1

Re: Any update on otehr problems?

It's not random, it's if you short out certain pins on the GPIO its can kill the PMIC. Its more comon on 3B+ becuase its the only one that uses a PMIC.....

Just dying is extemely rare, but can happen. Just like any other equipment. If it dies under warrantee, get it replaced.

James Hughes 1

Are you talking about something from 6 years ago?

In fact, I'm a bit confused by your timing issues on usb bottlenck statement because that doesn't ring any bells at all.

James Hughes 1

Re: not skookum

Wow. Quite the rant.

Just to inject semblence of truth in, we have never provided full schematics of any of the Pi boards. so to say we are geting less open is an exageration. We have had to change a little due to to becoming more competitive - ie we need to maintain our competitive advantage to remain in business. Easiest way to do that? Keep certain aspected under wraps.

Mising component labels is a cost saving measure, and what we can fit in limited space. Not much more to it that that.

We do not have an elistist atitude. We welcome anyone to contribute to our linux kernel, our documenation, our projects etc. As we do get some really good contributions in all those areas. What we cannot do is open csource the GPU binary blob, because we do not hold the copyright on it - that is held by Broadcom. We release what we can.

We screw up, everyone does. This is a case in point. But we've come clean, which is more than most other companies. Be nice to understand what you mean by your last paragraph, taking in to account this exact example.

James Hughes 1

Re: So what you're saying is...

Actually, not enough....

James Hughes 1

Re: Hats off to 'em...

TBH, we should have spotted this in testing, so there will be changes to help ensure it doesn't happen again!

James Hughes 1

Re: Oh dear, a fan

You can turn the fan off if you wish. Usually it's controlled by the Pi itself, so only turns on when required, and will be sped up/slowed down as necessary. If off, then the Pi will use its normal temperature control system, which may throttle the CPU if it get too warm.

Wow

Anti-Tesla anti-Musk forces are out in force today.

I'm more of a optimist. Tesla will fix production (AFAICT, it's pretty much already fixed), Model 3 will continue to sell shitloads, autopilot will get better, other manufacturers will all release full electric cars in the next 2 years, Tesla shorters will lose their hats (good, shorting stocks and trying to force the stocks down when they won't do it by themselves is a pretty offensive way to make money)
