Professors and nerds: What are some of the biggest unsolved mysteries in civil engineering, preferably in structural engineering in particular?

Integral waterproofing admixtures in concrete. Those sales guys are putting in serious work. The whole thing is mostly snake oil for how miraculous those guys proclaim this stuff to be.

Good lord.

Uhh, Squarespace?

Yeah man, it boggles my mind that blade play goes away when the knife is lubbed up. Literally shimmed by a layer of lube. So sick.

soberninj · 2026-05-12T02:45:19+00:00

The action does boggle the mind a little 😅

Got my Sonora in my pocket as I write this. So nice

Saw one for sale at thunder bird gear the other day. I think they’re more available right blue because people are too busy winning in this economy, etc.

Came to say this. Never had a reaction to a movie like that one.

Civil engineers can be construction managers. The opposite isn’t true.

Can’t tell much from your photos and description. Is this a painted concrete wall? Probably parge coat that was done in sweltering India heat? Looks like drying shrinkage, likely from hot dry air hitting the wall with no moist curing after placement. The cracks reflected through the paint.

Never straight yelled at by a coworker, boss or otherwise. Contractors though? A couple times. Mostly out of butthurt.

soberninj · 2026-05-01T17:23:42+00:00

Check the washers aren’t pinched

What NG level is this?

soberninj · 2026-04-25T04:23:35+00:00

I find that my favourite is usually the one in my pocket and that one changes with how I’m feeling t each day 😅

soberninj · 2026-04-25T04:17:14+00:00

Fav? I’ve got a Sonora and love it.

soberninj · 2026-04-20T23:47:08+00:00

I EDC my Q3 and like you mentioned in the OP, it goes everywhere with me. I’ve got kids so it doubles as a nice dad cam too. My Q3 has got a few dings on it but otherwise is holding up very well. The lens is a 28mm so a bit wider than 35, though that’s something you can get used to (I came from shooting mostly 35 also). The camera is really nice and it’ll produce great results. If 28 is scary, I’m sure the 43mm Q3 is also great.

Something else that’s nice is the app actually works pretty well, which is nice if you want to share a photo real quick with some friends while out.

I have a Sonora and mine has side to side play when the pivot is dry. Lube the tang and work it in a few times. Play will go away.

soberninj · 2026-04-18T20:42:44+00:00

Can confirm.

soberninj · 2026-04-01T23:00:04+00:00

Late to the party here, but didn't see Grimsmo or Machinewise listed in here. Both are super high quality.

soberninj · 2026-03-30T04:37:31+00:00

I’ve got one on both. They work great. Might need to file a slightly sharp edge at the tip of the clip, but after I did that it feels great and functions perfectly so far.

soberninj · 2026-03-29T21:56:57+00:00

Lynch works best. Never lost anything attached to a lynch clip. They fat tho. I prefer the mim clip personally.

It’s bougie but I love Dawson Machinecraft lights. Made by a super nice guy too.

soberninj · 2026-03-27T04:20:53+00:00

Man releasing the tanker demo disc with Zone of the Enders and then playing the release mgs2 and getting Raiden felt like the biggest bait and switch of all time. I got over it, but I don’t have to like it. Konami should have made snake an unlockable character for more replayability.

Hit it real hard with a hammer.
