What I don't like about TFA is the inconsistent, sloppy use of coordinates. Initially x,y,z are relative to the viewer with z going from the eye to the object. Some paragraphs later x,y are the horizontal plane with z going up. Then x and y are swapped (to overlap x onto y you have to rotate it 90° clockwise, the opposite of trigonometry's standard), only to be swapped again in the picture that shows the value of the…

Yeah, small inconsistencies and some hand wavy language put me off from reading the entire article. Like, what do you mean by "vertices appear bigger in perspective projection"? Vertices are just coordinates in space with no size.

Noted.

Back in my days, Google worked. Now it is a waste of time. Someone that wants to hold himself to the notion that Google was/is good really looks like someone having issues getting old

Any alternative to Google?

Yes, lots of them, but they are all just a matter of not giving all your search data to same company, non I know work better in this regard, in finding good forum posts or logs to answer questions you have.

Kagi (I'm a customer) works much the same way google did in 2010 or so.

To add to that, people (at least in my org) resort to ask "ChatGPT" for all sorts of questions. I don't share that sentiment, but oth, I never had trouble finding what I was looking for using Google. I agree though, it get's tougher with all that walled gardens. I guess I'm becoming the old, grumpy "back in my days, we used Google!" type of guy.

Google still works for me, but you have to generously apply “tricks” like verbatim mode, double quotes, time ranges, domain filters, exclude terms (minus sign), include search terms that bias it towards forum results, and so on.

I looked up Kagi and their sources include "AI" - do you know if one can turn this off?

weirdly enough, when asking for documentation/problem solving types of questions - chatGPT actually is a good alternative. you still have to double-check since you can't trust it... but you shouldn't trust random google results either, so that's not a big change.

it's kinda weird how the web has increasingly become optimized for bots - and filled with content created by bots... to the point where as a human you now need a bot to cut through all the bloated SEO bullshit and filter out what you actually want to know...

I have generally ignored game development but I honestly it’s not for lack of respect - most of computer science is represented in good game dev

I used to say that video games do everything you might find in any other kind of software - only difference being, they do it 60 times a second.

Bing is ok for results, but tries to push too much crap on you - do you want to link to your microsoft account? We've got rewards for you, are you sure you don't want to link to your microsoft account? Have you tried our copilot AI? Do you want to switch to Edge as your default browser? Did you know you can link Edge to your microsoft account? Here's some news from a scummy right-wing tabloid paper on the home page that you might be interested in.

I think in the default windows setup, your bing searches are "integrated" with your user account in some way.

Look, I don't mind the top 2 search results being ads (if you make them visually distinct from the rest), but I don't want all the other crap.

Bing's engine through duckduckgo is better. The ads don't get in your way once you've learned to start reading at the third entry on the page.

Really cool music on the "character screen" (~6:33). Takes me back.

That’s awesome. > The sort of thing you'd solve in 30 seconds with Google in 2024. This is unfortunately becoming increasingly untrue, as the forums where stuff like that was posted are rotting away, and Google’s advertisement optimized result ranking neglects the long tail. And to the extent it is still true, it’s because pioneers like you figured it out and shared their results!

I've become a paranoid link hoarder because of this.

I'm Pretty Sure these things are true in comparison to the past:

- There is much more high quality content on the web than was ever before.

- The signal to noise ratio is _much_ smaller.

- Search results are getting cluttered by SEO spam, some of which is straight up copying from organic social media style sites (forums, SO, reddit, Github issues etc.)

It's extremely hard to find good content, even though _i know_ it is out there. Sometimes it's even hard to find sites I visited before, but I only remembered vague keywords.

And this is true especially for content that is of educational nature or interesting punditry. You know, the stuff that comes directly from people who have expertise and have earned a grounded opinion.

This is why I'm hoarding links to all sorts of interesting things. It's not an efficient way to do it and I don't know if there's a more general solution here. Very unfortunate.
