bjarneh··on The Yaml document from hell
> There were two changes to it in 2005 (the removal of comments, and the addition of scientific notation for numbers)

They actually had comments in JSON but removed them in 2005. That is odd and a bit annoying :-)

Are there any real alternatives? In my opinion reviews on booking.com seem even stranger...
bjarneh··on Na-S Battery: Low-cost with four times the capacity of lithium
Yes of course, I meant to say 1 kW·h = 1 kg; but I'm not certain if I remember correctly now; I could be off by a factor of 10 I guess. It was either 1 kg battery weight = 1 kW·h, or perhaps he said 10 kW·h had to be contained in a 1 kg battery to allow all types of air travel.

I think the 100 kW·h Tesla batteries found in the Model S/X weigh around 750 kg; so I guess electric air travel is still difficult unless a battery breakthrough happens; at least in terms of weight.

Isn't that quite close to the magic number which makes electric planes a viable option? 1 kW = 1 kg; Musk said something about that in a podcast I think...

Lets not forget gold diggers, influencers, and poor people commuting in from France/Italy every day to all the boring work. Sounds like a pretty cool place!

bjarneh··on Caterpillar offers phone with built-in FLIR camera
Yes, but they make the phone look and feel just as bad as those CAT phones :-)

This time I actually kept the plastic cover on my phone - at least the back and sides are covered, and it sticks out about 1mm above the screen, so it has some protection from cracking the screen; but I still managed to crack it on my first attempt...

bjarneh··on Caterpillar offers phone with built-in FLIR camera
Every time I crack my screen I swear that next time I'll get one of those "rugged" phones. My last phone purchase (Asus Zenfone 8); lasted exactly 2 weeks before I cracked the screen on my bathroom floor. I was worried about having "only" 128Gb of storage; guess I should have been more concerned about that screen. Nice device though...

bjarneh··on Why Twitter didn’t go down: From a real Twitter SRE
> Slack space leads to innovations

I'm certainly no supporter of "lean operations" with minimum staff etc, and fully agree that you need people that are well rested (for the lack of a better analogy) to do great stuff. But I do think that some of these internet giants do have to many people working there; wasn't LinkedIn 14_000 strong when Microsoft bought it?

I've always felt that the American model of doing business is based on how we optimize network traffic, i.e. double the amount of data until failure; then turn in down a bit. Fire on all cylinders until people are truly worn out, then turn down the pace a bit. Haven't worked in the US so I'm pulling this info out of thin air...

bjarneh··on Kite is saying farewell and open-sourcing its code
> I'd imagine the resources they devote to it are quite limited

That's a problem inherent to AI or neural networks. We cannot spend our way out of these problems; they are underlying to the technology itself. Nobody knows what "doesn't work" when a neural network does something unexpected. AI is not a technology we have invented, it's a technology we've copied from nature. Nobody knows anything about what really goes on, this is why we're not getting anywhere.

Google could spend their entire budget on that smudge-bot, and it still wouldn't get any better using AI; they would have to go back to regular image analysis to make any improvements at this point. Google has trained it to be so good at finding faces; it started smudging faces on billboards/ads/shop-windows, but when these are flagged as errors, then it starts showing regular faces in shop windows un-smudged. The problem is that we have no idea of what's going on, so all we can do is to add new layers to the neural network, or give it more training data, neither of which gives an accurate result typically, making it impossible to use for self driving cars etc.

> I was partly expecting the rest of the article to explain to my why exactly it wasn't just bloat

Same here. I guess his header was on point in why Twitter is still up; but I was also interested in hearing about why Twitter actually needs all those people. If it can be run with 50-80% of the staff gone, that does sound like some bloat at least.

> The AI hype is finally over.

At least partially over. It's one of those things though; when you first see what's possible with neural networks it does get your hopes up. When you later realize the limitations, it's hard to walk back your old claims. Even Elon Musk has to realize that FSD is never going to happen by now. Google with all their learning and training data, still can't correctly find and smudge license plates or faces correctly on Google maps. If that much processing power cannot correctly identify two classes of objects, what chance do these cars have to classify tons more objects + adapt how they steer based on that information in real time?

bjarneh··on Sapling: A new source control system with Git-compatible client
Absolutely. I guess most of us have a bunch of repos which are personal anyway which are just as easily "hosted" as Mercurial repos. I.e. if I have ssh access to a machine, "hosting" a remote Mercurial repo with

    hg init
instead of

    git init --bare
does not matter to much..
bjarneh··on Sapling: A new source control system with Git-compatible client
> and there are still those of us who actually use Mercurial

I'm certainly in that camp; and it pains me every time I have to use the hggit extension to convert a mercurial repo to git in order to work with everyone else...

> Investing in Darn Tough socks helps.

Thanks for the advice. In the army we got the opposite advice, they said we must never use woolen socks when we did the 30 km march, always use cotton they said...

bjarneh··on The positive effect of walking on creative thinking (2014) [pdf]
This was something I heard very often from fellow pilgrims on the camino. That the constant abuse, really is something else. There is a ton of shoe stores along the camino, and plenty of people that "just have to wait a bit" for their feet to catch up. I guess both shoes and socks are important; but certainly never do what I did and go to Spain with brand new shoes...
bjarneh··on The positive effect of walking on creative thinking (2014) [pdf]
Probably, but I wore brand new shoes the first time I tried walking the camino, and that's a big no-no :-)

> I just looked it up and it says you can choose one of many routes.

Yes, I've done small parts of the route on two different occasions. First time I quit due to problems with my feet, the second time I quit after problems with the heat :-)

I never planned to go the full camino, as most of these routes are quite long. The one that starts in France is about 800 km (500 miles) I think, so that will be a full summer holiday and probably a few weeks off work at best. Not ideal to walk during the height of summer either, as the heat can be brutal.

> 20 km per day (~12.5 mi)

That is some serious distance. I remember thinking I would be able to do at least 25-35 km per day, a few years ago when I walked parts of the camino de Santiago in Spain. Blisters and destroyed feet in just a few days, not ever reaching 30 km per day I think.. How long did it take you to get used to this kind of distance daily?

Not all of us have left Firefox behind of course, but we are certainly not what we used to be.

We should; and especially in browser-engine-land. WebKit/Blink are becoming a monopoly..

bjarneh··on Someday aliens will land and all will be fine until we explain our calendar
It could be, but since it could also be interpreted as sometimes used, I wrote a comment to say that we use the 12 hour system exclusively when we speak about time, and the 24 hour system for written purposes. Perhaps that's what he meant, but I'm not sure...
