It’s worse if you stop using the phrase ‘buy’ and instead use the term ‘rent’. A DNS provider could 10,000x your domain cost and there’s nothing you can do about it.

This actually happened to me, but fortunately I never actually used the domain. I registered tweed.dev intending to use robert.tweed.dev as a personal blog. It wasn't classed as a "premium" domain and the first year was £5 or something IIRC, which was half price compared to the normal renewal fee.

The next year they decided it was premium after all, and wanted to charge £492,000 for renewal. I still have a screenshot of that, although needless to say I don't own the domain anymore.

I remember Alone in the Dark (1992) as having a totally crazy rendering engine. Looking at footage on YouTube [1], I now see that a lot of the more complex background rendering was probably done offline.

The Sierra adventures at that time (Kings Quest V and the like) had painted backgrounds where the actionable items would stand out because they looked like crap.

Alone in the Dark was notable at the time for using Gouraud shading [1]. You can see the effect on some of the polygons here:

The reason I remember this is that it inspired me to spend ages implementing Gouraud shading in my own graphics library (written in assembly language), only to discover that flat polygons look better most of the time.

I'm mixed on the shorts. I like it when they do a "you fix this by pushing this button here" in 15 seconds instead of it being 8+ minutes so they can get mid roll ads.

robert_tweed · 2 years ago

I'd be fine with shorts if they didn't disable the normal player controls.

I feel like the author spent more time photoshopping Kevin Flynn graphics than determining if Tron is actually an appropriate or useful metaphor for this concept.

It feels like an example of Betteridge's law of headlines, despite not being a question.

The BBC and other examples are present in the article under this heading: https://darekkay.com/blog/rss-styling/#examples

Ah, I only skimmed the article and missed that. The BBC RSS feed was the main example I referred back to while I was learning XSLT around 2010-ish.

AFAIK it's the only major implementation of this technique. Most other big sites that provided an RSS feed didn't bother, and most of those RSS feeds are dead now. The BBC one has hardly changed since those days and it still works really well as a dual-delivery system.

If anyone is looking for a real-world example, the BBC does it:

For reference I was already pretty used to gaming in VR on inferior headsets before working on the Vision Pro, so I might be more forgiving of issues than your average person.

I'd say that eye strain wasn't really an issue at all for me. When you take off the headset after a while inside of it you kinda get a jarring transition back to normal vision instead of passthrough, but passthrough doesn't have any noticeable issues when you're inside of it. It's almost like waking up from a dream where stuff feels different and you can't exactly place why.

As for physical weight, it's lighter than other VR headsets I'm used to but obviously more than a pair of ski goggles. I'll echo MKBHD's thoughts that the most noticeable strain was on my nose because my lightseal (like the WWDC demos) wasn't as personalized as the version you'd get as a customer, so I fully expect that to be a non-issue.

robert_tweed · 2 years ago

How is it in terms of heat & condensation build-up? Is there a certain amount of time after which it starts getting uncomfortable?

Also, is passthrough good enough for things like typing, so you don't get an uncanny valley sense of the keys being just slightly off visually compared to your proprioception & touch?

Interesting. I wonder if this technique could be used as an olive oil purity/quality test of sorts? Maybe correlating a few samples of various kinds, along with some external form of verifiable testing, it may be possible to figure it out.

robert_tweed · 2 years ago

I'm definitely taking my UV torch to the supermarket next time. However, most good olive oils come in dark glass bottles, so I don't think it will be possible to check those. Might be interesting to look for variation among the cheaper EV ones.

The article mentions differences between brands, but IDK if there's a specific correlation with quality other than that fake olive oils certainly won't turn red/pink.

I don't have a green laser, but I just tried shining a 365nm UV torch on the various bottles of oil in my kitchen.

My good EV olive oil in a glass bottle goes a sort of pinkish colour. With the natural colour of the oil & the way the glass reflects/refracts light, it makes it look like copper.

I don't get the same effect with cheapo refined olive oil in a plastic bottle. I get a bit of fluorescence - the normal violet colour and much less than say a white piece of paper - but all or most of that is just from the container.

A small portable scanner. I don't take it anywhere I just got a portable one due to it's size so I can stick it in a drawer.

I've been able to save a bunch of space and get rid of 99% of documents in my filing cabinet by making a digital copy and getting rid of the physical ones. Now when I get an important document I scan it save it to a few places and get rid of it.

robert_tweed · 3 years ago

Why not just a scanner app for your phone? They work pretty well. I have a flatbed scanner that I keep stored away most of the time, until I need to scan a bunch of stuff quickly. If I need to scan the odd receipt, I use Tiny Scanner.
