Thinking about implementing a command pattern -like, with the difference that the command does not have an execute method but instead the receiver contains the execute logic (the command becomes a mere payload)
Hundreds of schools, hospitals, and other public buildings made from RAAC, a cheap, lightweight concrete, have to close—the victims of quick fixes and decades of cost-cutting.
This week I facilitated a session in a mechanical engineering course on values-sensitive stakeholder analysis. We talked about social and political challenges around renewable energy siting and how considering stakeholder values in design can improve outcomes for all.
we're running a half-off promo through January at Phobos Group for our RTG services! (the 1hr and 2hr offerings)
If you need an hour or two consult for redteam or blueteam related work, or could find a second set of eyes helpful in the short term, we're here to help!
If you don't like being told "I told you so.", never doubt the person whose daily job is to think of worst-case scenarios for any given project. We wouldn't have a successful career if we were bad at it.
My mind is blown away by this video! 🤯 I wouldn't have believed if someone told me they made this shit work today, let alone in 1910. Sometimes the ingenuity of humans is unbelievable!
Thanks to larger donations from guys like Joe Gebbia, to date Boylan Slat and The Ocean Cleanup team have deployed 11 solar powered Interceptors across several countries.
There's still a long way to go though to have these automated garbage collectors
in all the worlds most polluting river systems
So donate what you can to help this hard working group keep going.
YouTube algorithms just figured out I was an Engineer, and took my attention away from my work, to fascinate me with a Fixed Fire Suppression demonstration video.
We were once using Halon, but environmental concerns stopped that. This is the same principle, with a different gas agent.
We are the hero of our own story. We imagine that we can change the world.
When we create things, we imagine the good we can do. However, before you go too far down the road of making something, ask yourself: What if your enemies had this, and could wield it against you? would you still want it in the world?
Before you release your project, consider the consequences. How can it go wrong? How wrong can it go?
Technologies play an increasingly important role in archaeological fieldwork. If you are enthusiastic about archaeology and have talent in engineering or coding, please consider joining us!
As #genai takes over, tools like ChatGPT will be generating more and more code without any quality assurance in place. I firmly believe tools like https://codewarden.ai are very important to add to your tool chain. Basically, AI peer reviewing itself, you need to take a look at this thing.
This week I taught an ethics session in a class on engineered living materials. Before class we read about a brick made of plant fiber, fungus, and programmable bacteria, which could make temporary structures in disaster areas. In class we played a game about decision-making in that context, and discussed their ethical reasoning.
New #energy sources in aviation, and aerial #innovation in general, are subject to a lot of passion. Many commenters have very strong opinions about them. But we're #engineers, isn't it? We look at facts, not feelings. There is a wide ocean of possibilities between "this is all 💩" and "everything will be electric & #hydrogen". For instance, electric & hybrid propulsion systems or #EHPS are part of the future of #aviation – and not just #AAM by the way. 🚁🛩️✈️🔋
Just found out that Carnot's father was a member of the Committee of Public Safety during the French Revolution.
For those that don't know, Carnot's scientific contributions underpin the workings of thermal cycles and are critical to how steam power works (among other things).
For those that also don't know, the Committee of Public Safety were the guillotine people.
Thermal cycles... Revolution... there's a terrible pun here somewhere
Is there any professional air... person (engineer? physicist? Thermodynamics' enthusiast?) here who could tell me whether they'd be okay to use as general air filters in a DIY project with way less air pressure than a vacuum uses? 🤔
Earth’s atmosphere holds six times more fresh water than all of its rivers combined. So is it possible to harvest that water, in areas where people have no other fresh water source? Purdue University researchers have crunched the numbers, and have the data to show which atmospheric water harvesting methods work best in...
