kar1181··on US, Europe 'unrealistic' in fab expansion drive, says TSMC chair
I think Intel will do a good job of it. They have no choice if they get this expansion wrong they are done.

My expectations for Europe though, are sadly much lower.

kar1181··on Ghana will no longer sell cocoa to Switzerland
Similar things are happening in Croatia.
kar1181··on WhatsApp to move ahead with privacy update despite backlash
I think as a starter concerned (UK) citizens should write to their MP.

I wrote when the first news broke and got a pretty prompt reply it was being looked at. Then Facebook announced it's pause and the issue went silent.

Now it's rearing up again we need to likewise make sure it's on the radar of our MPs.

kar1181··on The Elements of Computing Systems, Second Edition
As others have commented, the original book was one of those little gems that once you read, you realise how blind you were before, and it is extremely accessible.

Often material is either too abstract or far too detailed, ECS managed to find the perfect balance where someone with a CS background can drill down to transistors and come back upwards again and really understand where they are going on that journey.

kar1181··on The Elements of Computing Systems, Second Edition
Logged in to say exactly this. I thought I understand computation after my degree, and this book, while far from perfect, did an incredible job of bringing fundamental computation to life in the readers mind.

I'm looking forward to diving into the second edition and hoping the second half is better than the first edition.

kar1181··on WhatsApp gives users an ultimatum: Share data with Facebook or stop using app
Children luckily are much more flexible and chop and change with the wind. It's the older folks once something is established it ends up becoming bedrock and super hard to change. Parents/Adults are busy if something 'works', there's a lot of resistance to changing it.
kar1181··on WhatsApp gives users an ultimatum: Share data with Facebook or stop using app
This is precisely the dilemma in a nutshell.

You have a choice but it's a bit like voluntary solitary confinement. Especially during a lockdown.

kar1181··on WhatsApp gives users an ultimatum: Share data with Facebook or stop using app
It's harder for US folks to understand just how much of a monopoly WhatsApp has in Europe and the UK.

Pretty much all of our school and local community communication happens via WhatsApp. I'd change to Signal or Telegram in a heartbeat, but the inertia is so great it's not possible.

It pains me to say, but we're getting to the point where companies like Twitter, Facebook and Google need to be treated like utilities or something so that such moves as these can be scrutinised and controlled more effectively as Facebook could pretty much (within current law) introduce whatever policy they like and users would be faced with the option of accepting or being cut off from their local community.

Given the pandemic and the UK lockdown, this is not tolerable.

kar1181··on Quake's 3-D Engine: The Big Picture by Michael Abrash (2000)
I forgot to add, Michael did a post-mortem at GDC a year or so after shipping and you can access it online still (requires Flash though?!)

kar1181··on Quake's 3-D Engine: The Big Picture by Michael Abrash (2000)
Oh man - of all my 'nerd crushes' Michael is at the absolute top.

I feel like he hasn't been risen up to the stature of John Carmack but if you look at the things he's shipped in his career (no less than Quake AND Windows NT) and at the sheer volume of content he produced during those halcyon days in the late 80s/90s when the PC emerged from dumb as rocks beige business box to premier gaming platform, he is a key figure.

I was too young and grew up too remote to have access to his writings as they were written but as an older engineer going back over his Graphics Black Book, the Zen of Assembly books and his Dr Dobbs articles, there's a lot of lessons that you can learn that still have a lot of value today.

Actually one of the best lessons - and most easily accessible - is in the first chapter of his graphics black book, he talks about the human element of optimisation, and that it is critical to optimise the right thing. He uses an example of a engineer he knew that in the era of early electronic calculators (still clunky and and slow, but getting faster all the time) honed his slide rule skills to wipe the floor with any desktop calculator operator. But he was spitting into the wind, it was clear calculators were getting faster and there was no more road with slide rules.

Ultimately he wasted effort on a legacy technology rather than leveraging what was up and coming.

In many ways this mirrored the PC, in its early days, it was slow, dumb and unwieldy, but it was improving at a rate of knots and eventually came to dominate.

Both Michael's Black Book and Zen of Assembly are on Github and maintained as PDF, Epub and other formats. They aren't terribly applicable technologically to computing today but they are very readable and contain a lot of general purpose problem solving and optimisation tips that are as applicable today as they were then.

https://github.com/jagregory/abrash-black-book

There have been few technical writers emerge that match Michael Abrash and it makes me so happy he's still hacking away at interesting problems today. Shame he doesn't write as much as he did, but I'm sure he's busy trying to usher in the metaverse (snowcrash had a big influence on him)!

kar1181··on A Kid, a Minor Bike Accident and a $19,000 Medical Bill
No - the only implication is that the UK wouldn't use so many (costly) resources for something as minor as a few stitches on a 3 year old.

But as a parent, it is YOUR 3 year old so you want the absolute best for them. The end result, I believe, would have been exactly the same had it happened here or in the US. Just I had a lot more confidence (at the time) seeing just how much was being done to ensure there was no scarring.

kar1181··on A Kid, a Minor Bike Accident and a $19,000 Medical Bill
It would have been fine in the UK, the difference would have been waiting time (we'd definitely not be in and out in 90 minutes here). Also we'd have had a junior doctor or nurse do the stitches.

End result would be roughly the same.

In some parts of the country it may be a longer wait than others. The NHS generally though are very good when you visit with very young children.

kar1181··on A Kid, a Minor Bike Accident and a $19,000 Medical Bill
When we lived in the US my daughter tripped and opened up her chin on the kerb. My wife having no idea what to do (go to Urgent care) went to the ER...

She had 5 stitches and was in and out in about 90 minutes. A plastic surgeon did the stitches and at one point there were 8 folks in the room.

She has no scar and the experience was very good.

We had full insurance, and when the bill came, it was ~$4500 of which we had to pay roughly $990 ourselves.

Still not sure how to feel about it - that's a high price for a few stitches, but if I had a choice of going to a UK hospital for free, or paying a grand to know my daughter will be perfectly cared for, assuming I had that grand, I'd rather pay.

Not everyone has that option though and that's the problem.

kar1181··on Your Computer Isn't Yours
The one thing that gives me hope is the pendulum of open->closed->open has swung back and forth so many times now that even as depressing as current trends may be, I'm confident things will swing back again.

Not sure when, but I'm certain it will.

It is one of those strange things, the more closed things become, the greater the incentive is to open them back up again.

The hacker ethic is still out there, just this recent boom has dulled it a bit. A steady diet of locked down computing will fix that.

kar1181··on Is there still somebody in the Cairo community who is able to make a release?
Enlightenment is what got my to try linux (Redhat hurricane I think it was) way back when.

It was very pretty and _very_ broken then, but e-term, which required a tonne of E libs, was the terminal everyone used to show off their desktop so you kind of lived with it.

kar1181··on Apple Silicon M1 chip in MacBook Air outperforms high-end 16-inch MacBook Pro
But can it run Crysis?!
kar1181··on Apple Silicon M1 chip in MacBook Air outperforms high-end 16-inch MacBook Pro
Did not know that, and indeed the pentium m / core / core 2 series microarches have done incredibly well.

I've become something of CPU collector in recent years, and I have a nice line of p6 cpus from thePentium Pro -> Pentium 2 -> Pentium 3 -> Pentium M -> Core 2 that conveniently sidesteps those awful Netburst p4 CPUs.

It feels like this (p6+) microarch has finally run out of road and needs a rethink. What 'saved' intel was a change in philosophy rather than chasing MHz they chased power savings. And with Apple's new chips that history is repeating itself (and appears to be with a similar outcome).

It's an exciting time for hardware again because Intel and AMD are going to have to react to this and I think there's still legs to x86, it's survived everything thats been thrown at it so far...

kar1181··on Apple's apps bypass firewalls like LittleSnitch and LuLu on macOS Big Sur
The linux desktop experience is still quite in a state. I will likely do the same and suffer Linux, but I think many will go back to windows as WSL continues to improve.

Apple is going to lose developers.

kar1181··on I miss Microsoft Encarta (2019)
We had a very permissive culture around the PC equipment, pretty much if a computer was free you could use it. There was no authentication or use policies. That did change towards the end of my schooling when networking and internet access was finally rolled out. Novell Netware ruined everything!
kar1181··on I miss Microsoft Encarta (2019)
That whole period of the PC industry where 'multimedia' became mainstream was pretty magical. I know the Amiga was well ahead of the PC ecosystem for a long time in capability but it never hit schools (at least where I grew up in South Australia) like PCs did. So with the emergence of VGA and Super VGA, widespread availability (and relative affordability) of 486 DX class PCs, Soundblasters and Optical Drives, the PC overran the other home computers.

Games and applications were evolving at break-neck speed and the pace of change really made you feel anything was possible. Encarta was really a product of that time.

If you were doing primary / secondary school during the 90s, you'd have had to do projects where paper encyclopaedias were your primary resource. For me in a rural school it wasn't until the mid 90s we had 486PCs with CDROM drives and going from Britannica to the searchable rich media database that was Encarta was a massive force multiplier. It was a remarkable demonstration of how positive an effect technology could have on the learning experience.

kar1181··on I switched to Linux after using Windows for 10 years
Slight opposite take on the state of linux vs windows is here - https://www.dedoimedo.com/computers/linux-year-of-dissatisfa....

I unfortunately agree with a lot of what he says (this after using linux either a primary or secondary desktop OS for over 23 years) have kind of the same fatigue.

It really saddens, this current state of the linux desktop.

kar1181··on AMD Zen 3/Ryzen 5000 announcement [video]
My last AMD processor was the Athlon 64 x2 circa 2005, it's going to be nice going back.
kar1181··on Irish Court Says Subway Bread Is Too Sugary to Be Called 'Bread'
Really depends which supermarket and which location. The large supermarkets have a large choice (though you are right, not on par with the French, Dutch and Germans!). We do have a lot of local bakeries though which fill in the gap left over.

Now compared to the US (and I'm sure there are areas where you can be well served) it is a desert for bread. You may get the odd 'artisanal sour dough loaf', but the very fact it's shipped from california and will last 2 weeks makes you wonder!

kar1181··on Irish Court Says Subway Bread Is Too Sugary to Be Called 'Bread'
I was really shocked moving from Europe to the US how all but very select bread tasted like cake/brioch. First thing I always did getting back to England was buy a loaf of Hovis seeded multigrain and make a decent ham sandwich.
kar1181··on Microsoft to acquire ZeniMax Media and Bethesda Softworks for $7.5B
Microsoft now own Doom, Quake, Wolf, etc IP. They own id software.

2020, I'm done.

kar1181··on Computerphile: From Algol 60 to Pascal [video]
Computerphile, for me, is one of the gems of youtube.

That such incredible, well produced content like this is 'free' and so easily accessible is mind boggling compared to the efforts I had to go through in the late 80s learning computing independently.

kar1181··on What does Microsoft want with Linux and Open Source? [video]
They want developers. OSX gave us Unix AND a sane desktop.

Ultimately MS over between 2010-2020 lost developer mindshare and they weren't going to get it back. So pivot time and now we have Linux all the things.

Once they have developers back..., well, who knows what they'll start doing then.

kar1181··on MacOS Catalina: Slow by Design?
I've spent surely coming up on years watching and reading all the content you've either created or helped produce. Indeed some things may have improved, but I sure enjoy the heck reading and watching all your exploits with 'legacy computing'!
kar1181··on MacOS Catalina: Slow by Design?
I've been doing some network programming lately, specifically low level raw socket work. Sitting there with wireshark running the sheer volume of traffic with applications dialing home was kind of shocking.

I mean, I know it's happening, I (sadly) expect it to happen now. But seeing all the bits whizzing over the wire brought home just how much your machine is reporting about what you're up to.
