Teensy weensy space shuttle flies and lands

Re: 1.5G

Not astronauts, generally, but experimental stuff, like zero g grown crystals, which require low accelerations forces to survive to the ground.

Los Alamos National Lab fires up 750-node RPi cluster

James Hughes 1

Re: Pi flavour?

Also, you can buy The Pi Zero and Zero W in quantity, but they will cost more than the single unit price. I'd go with the Pi3, so much faster.

Re: Pi flavour?

Yes, the Ethernet and 4 port USB hub all go via a single USB port into the SoC. Yes, it is a bottleneck, no it hasn't really stopped a lot of sales, because in general people are not too worried about it. Those who really need the throughput get alternative devices and live with the less than useful support.

As for whether this is a toy, I'd suggest that if Los Alomos National Lab though it was a good idea to make one, then it's not really a toy. After all, it's not like the Pi is the new kid on the block with an unexpected design that will catch them unawares.

This is a project for testing code in an environment similar to the real HPC's, so you don't take up valuable compute time ironing out the kinks. It gives you 750 * 4 core A53 devices running at 1.2GHz, with slow interconnects and only 1GB RAM per node, buts costs less than $35k or so (my figures, not sure of final cost, assuming $35/Pi ex VAT plus costs for the Bitscope racks)

Re: Obligatory...

The latest Pi version is a quad core arm A53 running at 1.2gig so considerably faster than the original Pi model. They also support neon in the latest models so that if you can take advantage of it give you a massive speed improvement.

There's a thread on the Raspberry Pi forums that has a lot of linpack style testing done on it which might be worth a look if you're interested.

Re: Pi flavour?

Raspberry Pi make what is it about 500k a month or something ridiculous so buying in quantities is not a problem.

As for using something like a banana pie or an orange Pi yes they do have faster ethernet but the os support is absolutely rubbish. Since this is a educational project rather than a serious high-performance computing project it seems that the Ethernet is probably not that important anyway.

Munich council: To hell with Linux, we're going full Windows in 2020

Re: Jeeeezzzzzzzzzzzzzzzzz

I'd go for whining twat, but that's just me, a happy desktop/embedded Linux user/developer, who occasionally uses Windows as well.

Re: Virtualised WIndows

There is a single consistent GUI/desktop. The one you chose to use. Just ignore any others.

As for compiling applications, just chose one where the distro has already done it for you. I haven't had to compile an app for years, I just use whatever Canonical has in their repo.

And using one distro does not means a monopoly, since the kernel development is done out of distro land.

Note: I have Windows10 on the laptop, but only for web and some Windows only apps (not many at all). We handle a huge amount of stuff on the cloud (email, source control, bug tracking, office management, task management, which can actually be done under Linux as well). All of my software work in done on a Linux VM, or VNC to a Linux server, apart from a particular debugger which runs under Windows, but access the source tree on a Linux server.

Generally, the Windows fails exceed the Linux fails by quite some margin.

Dyson to build electric car that doesn't suck

James Hughes 1

Re: re: I'm just curious as to why

I've got a couple of Dysons and a Henry.

The Henry is shit at actually sucking stuff up compared with the Dysons. The Dysons (one handheld, one upright) are fairly robust. The upright has a broken bit of plastic, but is over 5yrs old and still works fine. One day I'll get round to fixing it. The handheld is great, cost about £80 IIRC, so maybe twice the cost of a really cheap nasty, but well made and very effective.

I have no issues with Dyson's.

Re: Solve this at the source

@itzman No you don't need to own a car that can do 200miles. You get an electric car, then hire something else for the long journeys.

Or just get a Tesla with >200mile range.

Re: You miserablists

Dyson is an engineer - certainly more so that Sinclair. The development of the original Dyson vac was done by him IIRC. https://en.wikipedia.org/wiki/James_Dyson

And you can keep your Henry, I'll stick with my Dyson that been running for years and actually sucks stuff up.

Re: Pollution impact

@Gordon JC Pearce

Not going to work. Tesla cars work so well because they are designed from the ground up to be electric. The battery is low down, the car built around it.

Not only that, but with electric you can get rid of much of the transmission which is power hungry, a drop in replacement would still require some sort of transmission I suspect. And where would you put the battery?

Compsci degrees aren't returning on investment for coders – research

James Hughes 1

Re: @tiggity re. all those JS coders

Hmm, I've been coding for over 35 years, still enjoy it, now earn in the top 10% (countrywide) working for the third biggest computer company (by sales) worldwide on really interesting stuff.

So being a dev isn't all bad. You just need to be good at it and find a decent job!

We have interns in who are VERY bright, even at age 18 they are well worth paying well. They could walk in to a job here no problem - and have. Helps being in Cambridge I suppose, with a good catchment.

Re: Peak Code Monkey

"Anyone can code"

No, not really.

"Not so much, as anyone with those other degrees can, if they don't already know, learn to code very well in a matter of weeks."

Even more, not really.

I'm not too bad as a coder (been employed doing it for the last 30 years with no gaps), and I learn something new almost every day. Although I do have a CS degree, it's hasn't been used to a huge extent, but has come in useful. But compared to how I started out I am SO much better now. And that only comes with doing to job for years. So, no, you cannot learn to code well "in a matter of weeks", unless your bar for decent code is really quite low.

Headless body found near topless beach: Missing private sub journalist identified

James Hughes 1

For a presumably intelligent person, Madsen seems to be exceptionally dumb. Headless/armless torso? Why? DNA will ID the body. Changing his story? Why? Changing a story implies guilt. Burial at sea? Weakest excuse in the history of the world - no one does that - they take the body back to shore.

A bizarre story, made more bizarre by completely irrational behaviour.

Re: If you're all in favour of strong female roles...

@phil.

Since the other Time Lords in the series HAVE actually changed gender, and there have been female timelords in shows, its seems anachronistic that the Dr hasn't been female yet. Assuming that the probability of changing gender is 50:50 (I suspect it isn't, it seems likely there is less chance of a change than remaining the same)), the chance of 12 in a row being male is only 2^12, so 4096:1.

About time.

Or something.

Re: @King Jack:

Having to add "It's a joke" to a comment or statement, reminds me of people who have to add "I'm not a racist but" to the start of whatever they are going to say.

It generally means exactly the opposite.

Or at least, if you have to explain that something is a joke, it's really not that funny.

His Muskiness wheels out the Tesla Model 3

James Hughes 1

Re: Mass market?

You could indeed get a 5lt V8 Mustang, but wtf would you? it would cost a bloody fortune to run, and the handling is agricultural. So basically a bit shit as commuter car.

Looking forward to the model 3, waiting for early teething troubles to be fixed, and the queue to die down a bit! And need to save up some cash.

Bonkers call to boycott Raspberry Pi Foundation over 'gay agenda'

Re: If only....

I think the choice here is:

1) Do I want to live my entire life emotionally and sexually unfulfilled

2) Or not.

Elon Musk reveals Mars colony rocket capable of bringing pizza joints to the red planet

James Hughes 1

Re: Fuel on Mars

Surprised that no-one has commented that this is simply a publication of the talk he did a year ago, so nothing new in it.

As for other points...

The Moon requires more Dv than going to Mars, so is actually harder to get to (and by get to I mean land on) and get back from.

This isn't fraud as some conspiracy theorist said above - Musk is currently revolutionising the Space launch business, and his company is almost certainly going to have something on Mars within 10 years. Might even be ITS, but will certainly be a Red Dragon.

Everything complained about above has been discussed ad nauseam elsewhere already. And in fact Musk is planning a new talk within a few months to go over version 2 of the plan.

Toyota's entertaining the idea of Linux in cars

James Hughes 1

Re: The REAL benifit

As someone who digs around in the Linux kernel to try and fix stuff, access to the source code is of benefit to very few people, despite the proclamations by many. The code is so complex you cannot really do much with it unless you spend a lot of time on it. And few people have that time.

Odd, all they are doing is MOVING offices from the already existing offices in Castle Park. They will be getting a few more staff I suspect, a few people are leaving... Raspberry Pi is in the same area, as are Microsoft. Parking/driving is impossible/crap, so I come in by train which actually turns out cheaper anyway. Impossible to actually buy any decent property in Cambridge unless you earn £150k, and even Amazon salaries don't hit those giddy heights for most softies.

Apple's zippy silicon leaves Android rivals choking on dust

James Hughes 1

Re: There are two different kinds of ARM licence

As Steve Todd says, Apple have an architecture licence, so they can design their own silicon that runs ARM stuff. And they do it very well indeed, their memory controllers are strikingly good (or was a couple of years ago), and they can make a huge difference. IIRC they are best in class with very good latency figures.

I am an Android user who won't touch Apple product with a barge pole, but does appreciate good silicon design.

ZX Spectrum Vega Plus backers complain of months-long refund delays

James Hughes 1

"Invested 0.5M"

Hmm, 0.5M doesn't buy you an awful lot nowadays.

Just design and injection mould for the case would take most of that.

Those people complaining of non-delivery and where has the money gone has no idea of the cost or timescales required to make something like this. Unfortunately, neither do the makers of the damn things. 0.5M was never going to be enough cash to do this, and the timescales are clearly hopeless.

Seems to be a thing with crowdfunding - lots of people thinking they can do better and cheaper, then finding out is not so easy to take a product to production.

Why is the Sinclair ZX Spectrum Vega+ project so delayed?

James Hughes 1

Most crowdfunded stuff that involves cases etc are going to run late. The people involved tend to be techies, good on the electronics side (HW and SW) but with no knowledge of packaging it up, And that is EXPENSIVE. You won't get much change out of £100k for tooling for injection moulding (if you do it properly), most people have NO idea of the costs of getting the plastic case for something right. Then add buttons, screens etc, and the fact you need to be able to manufacture on a production line, which is its own can of worms, and things rapidly get very expensive and time consuming indeed.

Linus Torvalds explains how to Pull without jerking his chain

James Hughes 1

Re: git shit

Er, no. Perhaps it's just that people submitting code haven't actually bother to lean how to submit code.

git is a PITA a lot of the time, but it is the Linux kernel SCCS. So, if you want to submit stuff, learn how to do it. It's not, actually, that difficult, to learn the minimal subset of commands required to do this properly.

Re: Why not just sell the on Amazon

On the other hand, for a limited resource company, you always need to be cautious. The RPF are not Apple or Samsung.

Being engineers hasn't stop the Pi from becoming the UK best ever selling computer, and it's catching up with the Commodore 64 for numbers sold, at over 12M. What it has meant is that you keep getting product that actually works, with actual support.

The ZeroW should be available in larger quantities than the original zero, for reasons you outline.

Google loses Android friends with Pixel exclusivity

James Hughes 1

Re: Y'know maybe....

Most people who have never had to work with the underlying architecture think this, but porting from one android version to another is unbelievably painful. Which equals very expensive. Under the skin Android is a horrible mess, almost incomprehensible to those without years of using it. It changes dramatically from version to version which means experience on one is hardly a help when you need to port your code to the next version.

Of course, maybe as a softie of only 30 years experiences in development I am biased towards code you can actually understand with documentation that makes sense, rather than how shiny it is, but YMMV.
