So in my quest to redesign a couple of Matrix protocol things, here's one thing that has been incredibly frustrating...

It's very easy to design deterministic algorithms that are efficient in most cases and only slow in uncommon cases. But those algorithms are completely useless in systems where an untrusted party controls whether something is the slow uncommon case... which is the case for most of a messaging protocol.

And designing deterministic algorithms that are efficient in most *real-world cases*, and resistant to artificial worst-cases... *that* is much more difficult!

HEY FEDI! How might you make some DIY trading cards?

I want something sturdy enough to stand up to a few decades of kicking around in a junk drawer. Ideally, I want custom wax packs to wrap them in, but I'd settle for printed foil.

I'm in favor of either a fully DIY option or a service I can hire.

Any ideas? Brainstorm with me!

random thought: I don't think Wikipedia will downfall in the coming decades but I think it might transform into one of those "infrastructure thingy a lot of stuff depends on but most people don't know about". For the foreseeable future it will be a popular household brand name

@whreq Yep, that sort of thing I could agree with, though at that point it's only tangentially about clothes IMO - it would be the same if someone constantly made shitty comments that made others uncomfortable, for example, it's more about maintaining a safe working environment.

The more nuanced version of my take is "the baseline should be that employers do not have a say in clothing, unless they have a particularly strong-weighing reason (like safety regulations, reasonable coworker complaints, etc.)".

(But unfortunately I've found that when I lead with the nuanced version of the take, the very first thing people do is try to invert it to "the baseline should be that they can, unless there's a reason not to" as if those are equivalent)

NEW by @rrix: Blocking Aggressive Scrapers at the Edge

In Limiting expensive to render nginx endpoints , I describe how to use a few nginx limit_req module to substantially limit the amount of aggressive scraping traffic to my Gitea instance without impacting "normal" "human" behavior.

There's three layered rate-limiters in here that are applied to only certain URIs:

One does a per-IP limit excluding my Tailscale network and some ASNs I connect from. Each IP can make one costly request per minute, otherwise receive a 503.
One tries to map certain cloud providers in to a single rate-limit key and gives each of these providers 1 RPM on these endpoints. Each group of cloud IPs can make one request per minute, otherwise receive a 503.
One puts a limit to 1 RPS of all traffic on each "site feature" in Gitea.

So now if you try to browse my Gitea instance http://code.rix.si or make a git clone over HTTP that will work just fine, but a handful of expensive endpoints will be aggressively rate-limited. If you want to look at the git blame for every file in my personal checkout of nixpkgs, you can do that on your own time on your own machine now.

So far installing this on my "edge" server seems to work really well, cutting the load of the small SSL terminator instance in half. Let's see if this is Good Enough.

Hot take: employers shouldn't be allowed to tell you what clothes you are permitted to wear at work.

(Don't bother responding if your analysis doesn't go beyond "but the company needs it!")

@gewt Aw! I'm really curious now, we don't have anything equivalent around here (in the Netherlands)

@Ninji (They are a major supplier of low-cost lightbulbs here, and practically the sole supplier of Action, a major discount store)

@Ninji lmao of course it's fucking Calex. Not the first time I've seen them come up with absurd branding for lighting products, though I don't recall the specifics of the previous cases anymore...

@Dee You need to at least use automotive duct tape to pass the roadworthiness tests

That's a problem for future me. I'm sure future me will be angry at past me about it - but thankfully I am current me, and neither past nor future me, so therefore *I* will never have to deal with the consequences

video game recommendations? 

I’m gonna be extra sick for at least 2 wks, might as well get some dopamine as a treat.

Looking for game recs which meet the criteria

- Journey
- Ghost of Tsushima
- ACNH and the Sims (decorating/dress up)

- Dream Daddy

Computer touchers shitpost about gremlins and shit when tech mysteriously fails, and I wonder how much of historical folklore is just this exact same thing happening for other stuff and some people taking the shitpost a little bit too seriously

Every Tesla is a surveillance device. This is worth knowing regardless of whether you plan to engage in protest activity.
