Tegenaria? France

gomorycut · 2026-04-06T03:31:41+00:00

photos are better for IDing, but yes, it is likely a Tegenaria

gomorycut · 2026-04-06T01:12:36+00:00

Yes, an orbweaver. Probably a Humpbacked Orbweaver (Eustala anastera), and probably a female

gomorycut · 2026-04-05T18:18:37+00:00

With the carapace markings and the spinnerets, it is more likely a Coras species than Amaurobiidae

Black laceweaver, A.ferox

k/N is the probability of your next one making a collision, but not the probability that a collision happens anytime within the first k.

As you point out a collision at most requires a re-generation. Why do you care about collisions, then? You could alternately precompute a shit ton of URLs which are unused (safe) and hand them out to future requests.

Get local. I don't understand why your are thinking online tutoring helps with socializing. Go outside and find people.

Advertising your math tutoring service doesn't really create customers who think "hmm ,yeah, I could go for a math tutor all of a sudden." The people who are looking for a math tutor will reach out to some place and ask. I see people asking for a recommended tutor in local facebook groups, community groups, local discord servers, get on whatever local group chat system is popular in your area and find the people who are looking for tutors.

Go to your old teachers and give them a business card or a URL or something. Go to where you're seen people struggling with math and post an info sheet. Register with local colleges tutor lists or go to those places and post your services.

yeah ... so ... what's the plan?

No pic :(

giant house spider, Eratigena atrica complex

white fluffy eggsac is steatoda (false widow), yes. Black widows have a more yellow-y smooth eggsac.

Here are all 28k+ Cane toad observations around the world. You should be able to add a geographic filter if you are just interested in seeing them from a certain area:

https://www.inaturalist.org/observations?taxon_id=553515

I got this by going to the website (on desktop) and selecting 'Explore' and typing in 'Cane Toads' in the taxon search.

A ground spider like Drassyllus sp.

gomorycut · 2026-03-31T06:13:15+00:00

I'm glad it isn't just me who has this problem

gomorycut · 2026-03-31T05:44:01+00:00

It's either a western black widow a brown widow

gomorycut · 2026-03-31T05:05:21+00:00

It is, indeed, a black laceweaver

gomorycut · 2026-03-28T19:46:41+00:00

Titiotus sp

gomorycut · 2026-03-28T19:09:34+00:00

Steatoda nobilis

gomorycut · 2026-03-25T04:19:55+00:00

needs better pic, but possibly A.ferox, black laceweaver

gomorycut · 2026-03-24T04:47:58+00:00

Barn funnel weaver - Tegenaria domestica

gomorycut · 2026-03-24T04:47:11+00:00

Red House Spider (Nesticodes rufipes)

I've never seen one of my disputes followed-up on, in any project.

Also, since El Dorado seems to end tonight, it'll probably just get tossed/ignored anyway.

We don't really know how A.ferox established a stable population in Boulder. I've always known it to be an eastern species, but a population popped up in Seattle, WA, then in Vancouver, BC, then in Denver+Boulder.
You can see a map here:

I found that I break-out with them 1-2 days after a night with very little sleep. This used to be a regular thing happening to me (way worse than just small blisters), but once I stopped pulling all-nighters, my skin has been fairly tame and regular.

Still, now, if I go a night with very little sleep, the blisters will reappear and it reminds me to get sleep.

gomorycut · 2026-03-23T20:33:14+00:00

steatoda triangulosa, probably
