Comment Re:I bet half the people who said "C" actually (Score 1) 249

We could see which bank it was writing to, but I forget now. It was one bit out, a high order bit.

How fun, for certain values of fun.

Years ago we contacted Microchip about these things, but all that ever happened was an errata and an apology so these days we rarely bother. I usually post Atmel bugs on AVR Freaks though.

I guess there's not a vast amount they can do, at least until they respin the next version of the hardware. At least an errate might make it easier for the next guy :)

I did contact TI with an error in one of their datasheet application notes. They never acknowledged it and simply deleted that bit from the next revision of the datasheet even though the fix was trivial (they'd mistakenly drawn one wire connected to -VE instead of ground). I was a bit miffed they didn't even bother with an apology or thankyou.

From your link:

Here I pause to remind new readers of this blog that I'm a trained hypnotist and a student of persuasion in all its forms.

He's also a certified genius level IQ. We mustn't forget that!

And I'm here to tell you that if you are afraid that Donald Trump is a racist/sexist clown with a dangerous temperament, you have been brainwashed by the best group of brainwashers in the business right now: Team Clinton.

Well, if you're merely afraid of that then you might have been brainwashed by someone. Anyone good at observing things (as Mr. Adams seems to think is important) actually *knows* that so there's no fear that he only might be.

And Clinton's team of persuaders has caused half of the country to see Trump as a racist/sexist Hitler with a dangerous temperament.

Turns out it's not just Team Clinton. I saw a bunch of pictures a while back 'shopping Trump with Hitler or something. Turns out that was done by his fans over at the Daily Stormer. No the hell way I'm going to dig through that again, but it's one of their "meme days" if you feel like taking a gander.

Not that I think Trump is actually a literal Nazi or anything, but it's just a funny counterpoint to Adams' claims.

But Trump is the bigger agent for change, if that's what you think the country needs.

Well that's stupid. The country needs change for the better, not simply "change". There are plenty of changes one can imagine which would make things much worse.

I'm not trying to say I'm smarter than anyone else.

I'm not but I am really. I mean I won't say smarter, but really I am smarter when it counts. Not that I'm saying it. But we all know I have a certified genius level IQ and I'm a trained persuader. And I'm so smart I know I'm not smart which ironically makes me much smarter than you even though I won't say it, but I am though.

I don't believe in a traditional god.

Oh that's new. He doesn't seem so keen on evolution either. He's written several posts with a "I'm not denying it but I really am" kind of flavour.

But, actually, in pre-history the BBC Acorn computer (which was the beginning of ARM) was expensive too.

True: it was about 5x the price of a ZX81 for example, though of course they weren't given away to pupils, they were destined for classroom use and the BBC Micro was much, much more physically robust than a ZX81.

I suppose what matters most is what the intended (and actual) use of the devices are and unfortunately it sounds a little half-cocked in the case of the Micro:bit.

As a Brit, I'm very annoyed by this, they could have just got behind the Arduino (for example) but no that was apparently NIH (Not Invented Here) so they've spent a lot of public money on this.

How much though?

Thing is, it's not a complicated board. I actually work on bluetooth stuff for a living and knocking up a uC, accelerometer and a few other bits and bobs on a circuit board is very seriously not hard. It's sufficiently not hard that I did a custom one as a favour for someone recently. When I say it's really not hard, it's really not.

Now, I've been using the CC2541 mostly for historic reasons. I've been meaning to jump over the nRF51 (used by the micro bit) and head straight for the nRF54 because HAVE YOU SEEN IT? Bloody awesome.

That aside, the peanut gallery (i.e. me) would have done it differently. I'd have used a ST Micro electronics accelerometer not an Freescale one mostly because then I could use SPI which I prefer (I2C is squirly and flakey, and much lower power draw which is something I happen to care about) and because I've used various of the ST MEMS sensors, I know they work well, I'm familiar with the interface and so I'd not change unless there was a pressing reason.

Anyway the important thing was that I had an onion on my belt as was the style at the time.

But back to it.

First, the arduino is great, don't get me wrong.

However, this board is not an expensive one to develop. This way they get much more control and have all the peripherals they want which you'll note is a lot more out of the box. When the BBC do something, they also go in big, and this way lets them control the supply chain so there's not going to be any worry about sourcing, and sourcing exactly what they want when they want in whatever quantities they need.

And those are large. They do (or did?) give them away to every yeat 7 pupil. That's about 700,000 per year, which as far as I can tell is about 3x the number of arduinos sold per year. And vastly more than any I/O shield. In other words they are so much larger than the entire arduino effort that it would require a complete revamp of the Arduino supply chain at which point, again, it's easier and simpler to simply do it themselves.

It's also a much larger MCU than many of the arduinos and not AVR. The advantage of the latter is that sadly few people work in GCC-AVR compared to ARM, making it a slightly less reliable platform. And the larger MCU also allows for things like micropython.

Of course they could use an ARM based arduino, but now you're dealing with a slightly fragmented platform and of course shields for the I/O. So they'd have to specify precise models (then deal with the fallout when people find cheaper ones which don't work) for both the controller and the shields, none of the latter of which do exactly what they want.

So maybe they should have made their own shield, but by the time you're there you may as well shove an MCU on it and call it a day.

In other words given the size and scale of what they're doing it was likely a better choice to make their own than try to cobble everything together with arduinos.

I do a certain amount of school volunteering and this is another thing that fragments attention and class time. I would have preferred full-fat pupil owned Raspberry Pis for example, a little more expensive but an order of magnitude more capable.

They are a *lot* more expensive. The RPi doesn't come with much out of the box. You need a PSU (many USB ports don't give out enough juice), an SD card, and probably a screen and keyboard to get going. This device is much more arduino like. They're not really comparable at all.

Still the BBC is a law unto itself.

The BBC's a huge organisation with many many interests. It's never going to be perfect and it's never going to do precisely the same as you.

You mean Trump likes the ladies? Is that forbidden now?

Again, are you being wilfully obtuse?

Tell me, do you like the ladies? I'm going to assume yes.

Would you bust into a changing room just to get an eyeful, even if you knew you wouldn't be arrested?

Would you find a lady you liked and just start forcing kisses on her?

Would you grab someone by the pussy merely because they let you (e.g. because you could ruin their career if they didn't[*])?

Because I, and many of my friends, as you put it "like the ladies", and none of us would do any of tose things because we're not raging arseholes.

[*] I wonder if you're going to complain about that clause. Before you do, I'd like you to think very hard about how a big, famous celebrity and an aspiring unknown might interact and the relative power imbalance, even if no threats are made.

Because they're trying to sell a narrative that WORDS are the equivalent of VIOLENCE.

Well, over here, solicitation to murder carries the same maximum sentence as murder itself, so sometimes yes, words and the act are taken to be more or less equivalent to importance.

This isn't just "voting with your dollars" and "refusing the patronize". This is ACTIVELY trying to damage a business by harassing its customers and physically interfering with people trying to do business with them.

Is it any less of censorship if thugs in brown shirts do it instead of officially designated organizations?

I know right, so someone expressed an opinion along the lines of "you're a dickhead and I'm not going to work with you" and legions of brownshirts start denouncing that person and those opinions because they're bad.


Or have I got it the wrong way round?

You know there *are* no brown shirts here. No one's beating up Theil or people working with Theil. However, one person has announced that she won't do business with a company that has Theil on the board.

So what do you think the right solution is? That she should suck it up and deal with him because business is more important for some reason than a principled stand? The only way capitalism can work is if people vote with their wallets. So fundamentally, no only is your stand very much against the spirit of free speech and free association it's also fundamentally anti-capitalist.

Scott Adams has a blog post on attacking the source, and claims it's almost always a "tell" for being guilty.

Well, despite his "certified genius level IQ" (his words, not mine) the guy's a bit of an idiot.

There is literally nothing wrong with attacking the source if the source is crap. For example, if someone points to "evidence" on Breitbart, I'm not going to read it, I'm going to point out their source is utter junk so I may as well ignore their point as unsourced. I mean sure, they might have had a correct fact this time (accidents happens), but what are the chances that it's just yet another post full of fake experts and unsourced claims like every single article I've ever read there.

Once a source becomes sufficiently tainted then the person using the source is not making a credible claim.

You know, like "good sense" and "Scott Adam's blog". I mean sure there might be some on there, but there's so much egregiously stupid bullshit that the fact it appears there I'll take as neutral at best and at worst a good point against. But hey, at least I'm not being cucked by sweater vests.
