2·1 year agoBirdtray might be what you’re looking for. I’ve only used it on windows, but for me it gets thunderbird out of the way but able to be checked and used immediately.
I’ve only got a water resources/environmental practice exam that has been passed around a lot. There is a decent amount of rudimentary soil mechanics and foundations, that I actually think is getting removed for that specific exam in the new one. The new structure means it might be a choice of piecemealing old content based on the NCEES topics list, or buying brand new materials.
I’ll probably be sitting the exam a little under one year from now, so I’m planning on doing the former until early next year, then hopefully my employer will buy some newer materials, or handle a bit of the cost, or maybe a review course at a local uni.
2·1 year agoJust yesterday I got a dell inspiron for this reason. It’s the “we have a laptop at home” macbook air IMO and I only logged into the OEM windows for the 5 min of checking out what’s new windows 11 before installing my OS of choice.
oh yeah, I forgot I watched about half of that video last week. He is really thoroughly knowledgeable and I enjoy his videos a lot, but it felt like a bit of a litany of arguments which is why I quit watching. However, the seismic argument is huge to me. Saying ‘Masonry houses can kill you here’ is a pretty strong argument in my book, especially when dealing with the realities of economics and what’s actually affordable/what’s cheapest.
This does a really good job of explaining the benefits of “stick” construction, even if he does get a little wrapped up in his hamburger analogy. I’m particularly interested in sharing it because of how many people online denigrate wood houses in the US, and I think this will show some of the real advantages of it as a construction choice.
That’s just way too vague to tell one way or another, and I don’t want to fall for marketing. Most concrete is made of mostly local materials, since the sand and gravel is quarried locally, sometimes on the same site as the mixing plant
One thing definitely lacking in the article and my brief look on their website is just… wtf even is the binder? Anything to truly replace portland cement will have to be non-proprietary and really well researched if they ever want it to take off.
Just find these types of scaled models amazing to see in real life.
And, of course, it’s actually being built. https://www.asce.org/publications-and-news/civil-engineering-source/civil-engineering-magazine/issues/magazine-issue/article/2023/07/zigzagging-weir-helped-solve-safety-issues-at-2-california-dams
And here are some videos on other physical models like this: https://www.youtube.com/watch?v=i70wkxmumAw

Finally, if you’re interested in the mathematics behind how we can do this and make comparable prototypes:

I haven’t read it yet, but the journal article this blurb is about is currently open access. Sharing it because I absolutely love this type of thing. I knew someone in school who was doing similar research with accelerometers on vehicles to try and assess the stiffness of the whole span. I think I sounded weird when I told him this irl, but I literally like to go to sleep thinking about being able to make measurements so indirectly and passively.
Sure are. I’m amazed how weird the picture ended up looking at that point, but I took another gander since I ended up there on my lunch break again. There are a couple of pieces of lumber run horizontally on the steel beam’s flange and the top chord of the truss is on top of those boards. I think it looks so funky because there are short pieces between each chord right at the very end
So true. I’d think that’s about the standard we’re used to with passenger cars, safety systems mandatory to be installed, and usage enforced by policing. I hope that the majority of people causing these wrecks are drunk and disoriented, not malicious, and that just giving them a convenient option to get home would eliminate 90%+
Obviously of note is the plumbed services manifold the Homeowner designed. He must have had a stinking absurd lot of money to throw at the house to start with, because I would have started out just trying to eliminate the need for the services. All electric appliances, roof drains off the side into a skirt of pea gravel at the base of the house, and maybe a holding tank for either water or sewer so that one or the other could be detaching from a “static” house position when the house it turned. That would be nowhere as luxurious and easy as this was (presented to be). Hope someone up to the maintenance purchases it and is a good steward
Been using some free time at work to make an inventory of pipeline stream crossings and plan on making it a GIS feature class for regular maintenance. This was inspired by an encased sanitary sewer essentially becoming a low head dam (just eroded, not discharging sewage) in a homeowners back yard and we were unaware until someone called.
It’s mostly just been tracing the features so far, but I’m thinking about where to take it next. Thinking a good direction to go next will be to use the elevation model to try and find manholes in high slope areas and ditches so they can be identified for monitoring for erosion or I&I.
I was introduced to wrong way detection systems early in undergrad when some grad students were grabbing people to be test subjects in their simulator. Strikes me as such a hard problem because it’s trying to control the human factor, and it is pointed out that the majority of the crashes are caused by drunk drivers. Have to figure that this is another problem that increasing automation in cars will help solve along the way.
Surfside sticks in my mind so much because it happened in my first week on the job as an engineer. That was only two years ago, but it really feels like the pandora’s box of deferred maintenance is just starting to swing open.
