Sandstorm is an open source
platform for self-hosting web apps
Self-host web-based productivity apps easily and securely.

Sandstorm is an open source project built by a community of volunteers with the goal of making it really easy to run open source web applications -- either on your own private server, or on our community-run servers.
Sandstorm protects you. Each document, chat room, mail box, notebook, blog, or anything else you create is a "grain" in Sandstorm. Sandstorm containerizes each one in its own secure sandbox from which it cannot talk to the world without express permission. All your grains are private until you share them. The result is that 95% of security vulnerabilities are automatically mitigated.

You choose where your data lives: You can use Sandstorm in the cloud on a variety of hosting services, or you can install it on your own machines. You can even move between these options at any time. No matter where you decide to run Sandstorm, the apps are the same.

With Sandstorm, you do not get locked into walled gardens. You can mix and match apps from multiple developers with ease, and even throw in apps of your own as needed. Many Sandstorm apps are open source, which means you can modify them to suit you needs.

Open-Source kanban. ("Trello" alternative)

Can import Trello boards

I have to admit, I've fallen in love with Trello as a productivity tool. If you like keeping lists as a way to organize your work, it's a very good tool. For me, it serves two primary purposes: keeping a GTD framework, and managing certain projects with a kanban-like schedule.

But Trello is a closed source SaaS product, and I wanted to know whether I could find an open source alternative to meet my needs. As much as I love Trello, it lacks a few features that I'd really like to have in a list/task manager, and I wanted to explore my other options.

PicasaStarter enhances Picasa and adds the following features:

• You can create any number of Picasa databases and sets of pictures. This allows you to have separate pictures /database sets for different projects or uses. For instance separate databases for vacations, hobbies, and jobs.
• Databases can be created in any location, including network drives, and can be shared by multiple computers and users.
• It is very easy to create a portable solution where the pictures and database are on a portable or USB drive. The only thing that must be installed on the computer is Picasa itself. This makes it possible to show and work with your pictures on any computer.
• You can create Shortcuts on your Desktop to start Picasa with each database. This gives one step access to any photo / database set.

NOTE: Unfortunately Picasa is a single user application and is not designed to share databases or pictures. This means even with PicasaStarter only one user at a time can be accessing each database and it's pictures. PicasaStarter warns the user if anyone else is accessing the same database.

To add customized buttons to the Picasa3 program, your computer needs to have a PicasaScripts folder for .BAT (batch command) files and an ExifTools.exe file, plus a separate Picasa database "buttons" folder for .PBZ (PicasaButtonZipped) files. Follow the directions below to set it up on your computer.

Image Composite Editor (ICE) is an advanced panoramic image stitcher created by the Microsoft Research Computational Photography Group. Given a set of overlapping photographs of a scene shot from a single camera location, the app creates high-resolution panoramas that seamlessly combine original images. ICE can also create panoramas from a panning video, including stop-motion action overlaid on the background. Finished panoramas can be saved in a wide variety of image formats, including JPEG, TIFF, and Photoshop’s PSD/PSB format, as well as the multiresolution tiled format used by HD View and Deep Zoom.

KiTTY is a fork from version 0.70 of PuTTY, the best telnet / SSH client in the world.
KiTTY is only designed for the Microsoft® Windows® platform. For more information about the original software, or pre-compiled binaries on other systems, you can go to the Simon Tatham PuTTY page.

KiTTY has all the features from the original software, and adds many others as described below:

“Everything about the design and manufacture of the Max was done to preserve the myth that ‘it’s just a 737.’ Recertifying it as a new aircraft would have taken years and millions of dollars. In fact, the pilot licensed to fly the 737 in 1967 is still licensed to fly all subsequent versions of the 737.” —Feedback on an earlier draft of this article from a 737 pilot for a major airline //

MCAS is implemented in the flight management computer, even at times when the autopilot is turned off, when the pilots think they are flying the plane. In a fight between the flight management computer and human pilots over who is in charge, the computer will bite humans until they give up and (literally) die.

The flight management computer is a computer. What that means is that it’s not full of aluminum bits, cables, fuel lines, or all the other accoutrements of aviation. It’s full of lines of code. And that’s where things get dangerous.

Those lines of code were no doubt created by people at the direction of managers. Neither such coders nor their managers are as in touch with the particular culture and mores of the aviation world as much as the people who are down on the factory floor, riveting wings on, designing control yokes, and fitting landing gears. Those people have decades of institutional memory about what has worked in the past and what has not worked. Software people do not.

In the 737 Max, only one of the flight management computers is active at a time—either the pilot’s computer or the copilot’s computer. And the active computer takes inputs only from the sensors on its own side of the aircraft.

When the two computers disagree, the solution for the humans in the cockpit is 
to look across the control panel to see
 what the other instruments are saying and then sort it out. In the Boeing system, the flight
 management computer does not “look 
across” at the other instruments. It 
believes only the instruments on its side. It doesn’t go old-school. It’s modern. It’s software.

This means that if a particular angle-of-attack sensor goes haywire—which happens all the time in a machine that alternates from one extreme environment to another, vibrating and shaking all the way—the flight management computer just believes it.

It gets even worse. There are several other instruments that can be used to determine things like angle of attack, either directly or indirectly, such as the pitot tubes, the artificial horizons, etc. All of these things would be cross-checked by a human pilot to quickly diagnose a faulty angle-of-attack sensor.

In a pinch, a human pilot could just look out the windshield to confirm visually and directly that, no, the aircraft is not pitched up dangerously. That’s the ultimate check and should go directly to the pilot’s ultimate sovereignty. Unfortunately, the current implementation of MCAS denies that sovereignty. It denies the pilots the ability to respond to what’s before their own eyes.

Like someone with narcissistic personality disorder, MCAS gaslights the pilots. And it turns out badly for everyone. “Raise the nose, HAL.” “I’m sorry, Dave, I’m afraid I can’t do that.”

In the MCAS system, the flight management computer is blind to any other evidence that it is wrong, including what the pilot sees with his own eyes and what he does when he desperately tries to pull back on the robotic control columns that are biting him, and his passengers, to death. //

It is astounding that no one who wrote the MCAS software for the 737 Max seems even to have raised the possibility of using multiple inputs, including the opposite angle-of-attack sensor, in the computer’s determination of an impending stall. As a lifetime member of the software development fraternity, I don’t know what toxic combination of inexperience, hubris, or lack of cultural understanding led to this mistake.

But I do know that it’s indicative of a much deeper problem. The people who wrote the code for the original MCAS system were obviously terribly far out of their league and did not know it. How can they can implement a software fix, much less give us any comfort that the rest of the flight management software is reliable?

So Boeing produced a dynamically unstable airframe, the 737 Max. That is big strike No. 1. Boeing then tried to mask the 737’s dynamic instability with a software system. Big strike No. 2. Finally, the software relied on systems known for their propensity to fail (angle-of-attack indicators) and did not appear to include even rudimentary provisions to cross-check the outputs of the angle-of-attack sensor against other sensors, or even the other angle-of-attack sensor. Big strike No. 3. //

In my Cessna, humans still win a battle of the wills every time. That used to be a design philosophy of every Boeing aircraft, as well, and one they used against their archrival Airbus, which had a different philosophy. But it seems that with the 737 Max, Boeing has changed philosophies about human/machine interaction as quietly as they’ve changed their aircraft operating manuals.
