manwithaplanon Enemy AI: chasing a player without Navigation2D or A* pathfinding

> The author called it "Dijkstra Maps".

> Basically it's about generating a heatmap for all the squares on the level.

> You can start with 0 at player position, and from that point use a simple floodfill algorithm, putting down increasing numbers with each step.

manwithaplanon The Polygons of Doom: PSX

Tangentially, I’d argue that it’s missing an HSTS policy of redirecting pages to a canonical HTTPS version; e.g. TFA should be linked as https://fabiensanglard.net/doom_psx/

manwithaplanon Gitlab 11.8 Released

I blame the misunderstandings on the non-standard syntax: > Yes but Gogs is self-hosted whereas Gitlab offers hosting solutions.

Replying that, to someone who literally said they switched from GitLab to Gogs for self-hosted repositories, also made me parse it as implying one word: > Yes, but Gogs is self-hosted, whereas GitLab offers [only] hosting solutions.

but the author probably meant something like: > Yes, but Gogs is [exclusively] self-hosted, whereas GitLab [also] offers hosting solutions [so switching is not always an option].

manwithaplanon NPR.org website – GDPR friendly, text only

Because the Decline button on the consent page redirects to their main https://text.npr.org/ homepage instead of the compliant text version of the desired article, I’ve started using a bookmarklet to manually fix this:

javascript:(function (){var s=location.href.split( '/' );location.href='https://text.npr.org/s.php?sId='+s[s.length-2]})()

E.g. when invoked on https://choice.npr.org/index.html?origin=https://www.npr.org... it redirects to https://text.npr.org/s.php?sId=618047447

manwithaplanon Introducing DNS Resolver for Tor

> but the .onion addresses use base32 and '1' isn't in the alphabet used

I see. Oh well, at least Google and Quad9 can’t, either (base32 digits stop at ‘7’).

manwithaplanon Introducing DNS Resolver for Tor

> I knew Tor Project has been shifting away from "hidden services" for a while

I read the article after your correction, and on reading the `What are Tor onion services?` section, I thought “How nice, they’re using the new terminology to go with the new v3 service address”.

But then, just below, I saw the https://blog.cloudflare.com/content/images/2018/05/image_3.p... diagram still mention “hidden service” and thought “an old image slipped thru, tho” :)

Also, wouldn’t a “1111dns4tor” prefix look better? :)

manwithaplanon How Ethereum can be stolen through DNS rebinding

From the previous discussion linked above: https://news.ycombinator.com/item?id=16563135

> I regularly encounter users who don’t accept that websites can access services on localhost or their intranet. These users understand that services bound to localhost are only accessible to software running on the local machine, and that their browser is running on the local machine – but somehow believe that accessing a website “transfers” execution somewhere else. It doesn’t work like that, but this is a common source of confusion.

manwithaplanon F-Droid 1.0 released

I also liked the message the first few times I’ve seen it.

But then I realized the parenthetical was false 99+ percent of the time (I’ll mostly see it when I’d just finished refreshing my repositories) and it became… irksome, exactly because it was mildly pedantic and technically correct.

manwithaplanon Announcing the first SHA-1 collision

Seeing how they ridicule MD5, I think they should have spent a bit more time on the proof PDFs, and have their MD5 digests collide also.
