Portable Air Conditioners – Why you shouldn’t like them…

01) Portable Air Conditioners – Why you shouldn’t like them


“Seriously, either we need to get more awareness of how dumb single-hose portable A/C units are, or we need to just use window units whenever possible. While I know that there are times a portable unit is the only option (remember, I’m in that boat), it seems that only very high capacity, premium machines have the facility to use two hoses. Which is frankly stupid but then again that’s what I’m trying to tell you now.”

Why Machines That Bend Are Better…

01) Why Machines That Bend Are Better


“I visited the Compliant Mechanisms Research group at Brigham Young University and spoke to Professor Larry Howell:

https://www.compliantmechanisms.byu.edu

At the above link, you can download 3D-print files to make some of the objects in the video, plus learn more about compliant mechanisms.

What I learned about compliant mechanisms I summarize in the 8 P’s of compliant mechanisms:

1. Part count (reduced by having flexible parts instead of springs, hinges)

2. Productions processes (many, new, different enabled by compliant designs)

3. Price (reduced by fewer parts and different production processes)

4. Precise Motion (no backlash, less wear, friction)

5. Performance (no outgassing, doesn’t require lubricant)

6. Proportions (reduced through different production processes)

7. Portability (lightweight due to simpler, reduced part count designs)

8. Predictability (devices are reliable over a long period of time) “

IPFS: A peer-to-peer hypermedia protocol to make the web faster, safer, and more open…

01) IPFS


“HTTP is inefficient and expensive

HTTP downloads a file from a single computer at a time, instead of getting pieces from multiple computers simultaneously. With video delivery, a P2P approach could save 60% in bandwidth costs.

IPFS makes it possible to distribute high volumes of data with high efficiency. And zero duplication means savings in storage.

Humanity’s history is deleted daily

The average lifespan of a web page is 100 days. Remember GeoCities? The web doesn’t anymore. It’s not good enough for the primary medium of our era to be so fragile.

IPFS keeps every version of your files and makes it simple to set up resilient networks for mirroring of data.

The web’s centralization limits opportunity

The Internet has been one of the great equalizers in human history and a real accelerator of innovation. But the increasing consolidation of control is a threat to that.

IPFS remains true to the original vision of the open and flat web, but delivers the technology which makes that vision a reality.

Our apps are addicted to the backbone

Developing world. Offline. Natural disasters. Intermittent connections. All trivial compared to interplanetary networking. The networks we’re using are so 20th Century. We can do better.

IPFS powers the creation of diversely resilient networks which enable persistent availability with or without Internet backbone connectivity.

IPFS aims to replace HTTP and
build a better web for all of us.”

I’d be lying if I said I was clear, as to what this is all about…but, I stumbled across a few web pages, while searching for an old website online…and they were hosted on this service.

Thought I’d share it, to see if anyone has anything to say about this.

Apparently, this is peer to peer content hosting?

Calibre E-Book Manager…

01) Calibre E-Book Manager

02) About calibre

“calibre is a powerful and easy to use e-book manager. Users say it’s outstanding and a must-have. It’ll allow you to do nearly everything and it takes things a step beyond normal e-book software. It’s also completely free and open source and great for both casual users and computer experts.”

I finally just got the most recent version of Calibre installed on this PC…

…I’ll be totally up front…It’s been years since I used this software…and that was a much earlier version…It did work well, for transferring e-books into different file formats [including PDF]…but, I’ve not tried much of anything with this latest version.

I’m out of the loop…so, I cannot offer any real advice on using this software…I still wanted to share the link.

01) EHANG 184 Autonomous Aerial Vehicle (AAV)

“Ehang 184 AAV is the safest, Smartest and Eco-Friendly low altitude autonomous aerial vehicle, aiming on providing Medium-Short Distance communication and transportation solution.

The 184 AAV is designed with full redundancy – If one set of the power system are operating abnormal, the vehicle can still operate a normal flight plan and ensure the safety of the passenger together with the vehicle.

The 184 was designed to be a 100% with green technology, and is powered by electricity only.”

02) The Ehang 184 personal drone is ready to fly [2017]

“Last year the Ehang 184 autonomous aerial vehicle (AAV)—what we might call a big-ass drone—was a prototype. This year it’s a real, flying vehicle, seasoned by 200-plus successful (non-crashing) test flights, and it just may start taking passengers for real in the near future.”

03) Ehang 184 Human-carrying Drone [2016]


“Anyone want to “E(hang)” out in the sky? This human-carrying drone will enable you to do that. It’s called the EHang 184, made in China and raised around $50M to date. It can also fly autonomously. Would you take a ride?
