Survey and Cartography Training
Saved by uncleflo on January 18th, 2022.
Surveying in caves is a hard and thankless task. We spend hours in uncomfortable locations working to obtain the data we bring back to create cave maps. However in several cases all the hard work put into the survey and sketching of caves has been lost. Either the data itself is lost due to a catastrophe or negligence or the project leader loses interest in the cave, project, or in several cases, caving altogether, and walks away with data. I started caving and mapping in Rockcastle and Jackson Counties Kentucky. Over time I saw many great mapping efforts disappear as people went on to other things, and the maps and data were not preserved. This site was started as an example how the internet can preserve and make available data over long periods of time. It started with Rockcastle and Jackson maps that I had worked on, then friends maps, and now is trying to capture the entire wealth of cave maps in these counties as well as surrounding counties.

Docker Basics: How to Use Dockerfiles – The New Stack
Saved by uncleflo on January 16th, 2022.
By using a Docker image, it is not only possible to deploy one container after another, it’s quite easy. Once you’ve pulled the image from a registry (such as Docker Hub), each container can then be deployed with a single docker command. But what happens when you find yourself having to deploy numerous containers (each for a different purpose) from the same image? All of a sudden the management of those containers can get a bit cumbersome. Say, for example, you pull down the latest Ubuntu image for development. Before you can develop with that container, there are a number of modifications you want to make to the image (such as upgrading software and adding the necessary development packages for the job at hand). For this, you could manually edit each image as needed (creating a new image for each necessary variation on the theme), or you could construct a Dockerfile for each variation. Once you have your Dockerfile constructed, you can quickly build the same image over and over, without having to take the time to do it manually. Carefully crafted Dockerfiles can save you considerable time and effort.

Arvel Gentry | North Sails
Saved by uncleflo on April 10th, 2021.
In the first edition of the Art and Science of Sails, written by Tom Whidden, president of North Sails Group, LLC, and Michael Levitt, and published by St. Martin’s Press, the authors used Arvel Gentry’s now famous Bathtub Experiment to demonstrate the existence of Circulation, or a second force, that operates around an airfoil, like a sail, wing, or keel etc. Big picture: it’s the combined effort of these two forces that makes the wind speed up on the leeward side — and thus show low pressure — and slow down on the windward side of a sail — high pressure. Gentry was the Boeing engineer who first taught sailors aerodynamics. These diagrams first appeared in Gentry’s Sail magazine articles. In the Revised Edition, the authors used computer testing to show where the wind speeds up around a sail plan and where it slows down. And why and by how much? Nevertheless, Gentry’s experiment is the standard — still popular on the web — and it was left it out of the Revised Edition with trepidation, but we linked in the book to this web page.

3 Biases That Hijack Performance Reviews, and How to Address Them
Saved by uncleflo on June 22nd, 2018.
When we talk about bias, we often tie it to acts of discrimination or prejudice. But according to cognitive science, everybody, by virtue of having a brain that’s constantly seeking efficiency, is biased in some way — and not all biases make us actively malicious. The key is how we manage our biases. While biases can affect any of an organization’s talent decisions, they can be especially harmful when it comes to diversity and inclusion efforts. And there is perhaps no setting that shapes careers, salaries, and lives like annual performance evaluations. In a recent performance management summit we ran with over 100 large organizations, 57% of them said they weren’t taking any actions to address bias in performance reviews. One reason why may be a lack of shared language: In order to address biases, you first have to be able to label them. Research has found that several biases come up again and again when managers are evaluating a team member.

Qualys SSL Labs
Saved by uncleflo on June 30th, 2017.
Qualys is the leading provider of integrated asset discovery, network security, threat protection, compliance monitoring and web application security solutions. SSL Labs is a collection of documents, tools and thoughts related to SSL. It's an attempt to better understand how SSL is deployed, and an attempt to make it better. I hope that, in time, SSL Labs will grow into a forum where SSL will be discussed and improved. SSL Labs is a non-commercial research effort, and we welcome participation from any individual and organization interested in SSL.

Brian’s 10 Rules for how to write cross-platform code
Saved by uncleflo on July 19th, 2016.
I’ve had a lot of success in my 20 year software engineering career with developing cross platform ‘C’ and ‘C++’ code. At Backblaze, we just released the Mac beta version of our online backup service, so I thought it an apt time to discuss my 10 rules for writing cross-platform code. We develop an online backup product where a small desktop component (running on either Windows or Macintosh) encrypts and then transmits users’ files across the internet to our datacenters (running Linux.) We use the same ‘C’ and ‘C++’ libraries on Windows, Mac, and Linux interchangeably. I estimate it slows down software development by about 5 percent overall to support all three platforms. However, I run into other developers or software managers who mistakenly think cross platform code is difficult, or might double or triple the development schedules. This misconception is based on their bad experiences with badly run porting efforts. So this article is to quickly outline the 10 simple rules I live by to achieve efficient cross platform code development.

The Magtenlight Company
Saved by uncleflo on March 23rd, 2012.
The Magtenlight Company is a Hong Kong based company dedicated to the design and manufacturing of innovative battery free bicycle lights securing maximum safety to the cyclist. A worldwide patented revolutionary bicycle lighting system: , no contact friction. Transfer your pedal power to the generator unit by magnetic transfer, for maximum efficiency. Unlike other battery free bike light systems available in the market, the Magtenlight Company provides lights for you to see the road and to be seen by others. The Magtenlight Company provides a revolutionary system which powers a 15 Lux superlight white LED on the front and a double RED led on the rear, with only one frictionless power generation system, constantly on, for you to see the road and to be seen by others. A constant light is best for the approaching motorists to estimate how far and how fast the bicycle is going.
