Spy in your fridge

PrintIndividuals deserve a clearer understanding of the data that companies are collecting from the new generation of digital, connected devices, said Vinton G. Cerf, Internet pioneer and Web evangelist for Google.

Mr. Cerf’s comments highlighted an ongoing debate that is gaining momentum as a growing number of connected devices, machines and objects, known as the Internet of Things, takes shape. As more devices connect to the Internet and collect data about users, who ultimately is in charge of it, and how are the data collection practices communicated to the public?

“It should be required that the users control this information that we accumulate,” he said Wednesday during a cybersecurity lecture at New York University’s Tandon School of Engineering. “They should have the ability to say no, I don’t want this device because I don’t want to be forced into providing that information.”

“That probably means the fine print needs to be a lot clearer than it is today,” he added.

A potential challenge is figuring out how to limit data access to certain parties, in certain circumstances. A person may want a doctor to have access to his or her medical records during an emergency, but may not want that doctor to have continuous access to electronic health information. “You need to have this ability to grant ephemeral access to information,” Mr. Cerf said.

In a panel discussion following Mr. Cerf’s keynote, a group of Internet of Things researchers touted the public and commercial benefits of being able to access reams of user-generated data. But some on the panel, which included Mr. Cerf, Cornell Tech computer science professor Deborah Estrin and Tandon School professor Beth Simone Noveck, cautioned against making data available solely to private interests, an outcome that could restrict consumer privacy and hamper public research efforts.

“Ultimately and finally this is an issue about control,” said Ms. Noveck, who directs The Governance Lab at NYU. “This is about getting our own data back about ourselves.” She also stressed the importance of finding ways to share societal information collected by private companies – such as weather and temperature data – with government and researchers to more effectively address policy issues.

Dry flush toilet

dryflush
No matter how you choose to live, off-grid, in a tent, a tiny house, a dome, everyone has to go to the bathroom. That is a central issue for those of us who choose to turn away from city living and utilities.

We chose to go with a DIY composting system, we looked at the various commercial composting units that are available, but ultimately decided it was too expensive up front, with the average unit going for over $1000, and honestly the reviews from people using them were OK at best. I have a friend who had an expensive commercial composting unit and hated it from day one, I watched her push it out the back door, I would have taken it but it had been left outside for a few years and the plastic had broken down…

While watching one of the tiny home reality shows over the weekend, they talked about a dry flush toilet, this one looked quite different from the other small, portable toilets I’ve seen in the past. I looked it up and discovered it has a simple design that works. It basically uses a plastic liner that encloses your liquid and solid waste, that is then contained in a larger plastic bag. It is said to have no smell and you don’t have to handle anything, which are the biggest negatives to nearly all the other toilet designs.

This uses a cartridge system that appears easy enough to install and remove, each cartridge is good for 15-17 flushes before it needs to be replaced. You buy the cartridges in 3’s, they run $50-$60 for 3 of them. I suspect if you really ran out of cartridges and were in a desperate situation, you could place a regular plastic bag in it and use that.

I wondered how heavy the bag would be when removing it, it would need to be easily handled, that’s probably why the cartridges are the size they are and not any larger. I also wonder how loud it really is, the plastic bag (inner and outer) seem very crinkly, and from what I have seen online, when you “flush” the toilet, the sound of the unit seems loud, so between the mechanical and plastic crinkle, you would not be doing your business in silence.

When you remove a fully used cartridge, you toss it in the trash, I believe it would be sanitary enough, ie no leakage since it is double bagged. And for those who wonder, yes it is legal to dispose of human waste in the trash, otherwise it would be illegal to toss baby diapers or adult diapers in the trash.

If I had to start over, and didn’t have such a talented hubby, I would definitely look at this system, the cost of the toilet unit is around $500 and can be ordered through Home Depot …
