Yikes! Looks hopeful as of 3rd of September they say the following on facebook:

> Just a small mid-late month update. Thanks again to everyone who has donated. Small and big all donations make a big difference for our prototyping effort. We are now just waiting on coils and cnc to come through which should be a week or so. We finished clearing away all the rubble from the fire and the new shed is now built and sealed ready to start housing REVR! We have had some very productive discussions and vid calls with people looking to help make REVR happen which we may be able to elaborate on in future. We have also entered the Samsung Solve For Tomorrow comp to promote REVR. There is some more good competition news we can't wait to share. Will have some more substantial updates very soon. - Alex

Keppl8R··on Whats Is Foveated Rendering?
Foveated rendering is a rendering technique which uses an eye tracker integrated with a virtual reality headset to reduce the rendering workload by greatly reducing the image quality in the peripheral vision (outside of the zone gazed by the fovea(The fovea centralis is a small, central pit composed of closely packed cones in the eye. It is located in the center of the macula lutea of the retina.))

Keppl8R··on Why Do U.S. Electrical Plugs Have Holes in the Blades?
1. If you were to take apart an outlet and look at the contact wipers that the prongs slide into, you would find that they have bumps on them. These bumps fit into the holes so that the outlet can grip the plug's prongs more firmly. This detenting prevents the plug from slipping out of the socket due to the weight of the plug and cord. It also improves the contact between the plug and the outlet.

2. Electrical devices can be "factory-sealed" or "locked-out" by the manufacturer or owner using a plastic tie or a small padlock that runs through one or both of the prong holes. Construction projects or industrial safety requirements may require this type of sealing. For example, a manufacturer might apply a plastic band through the hole and attach it to a tag that says, "You must do blah blah blah before plugging in this device." The user cannot plug in the device without removing the tag, so the user is sure to see the instructions.

3. There also is a small savings in raw materials (metal) for the manufacturer of the actual plug prong. Every little bit helps!

It has been reported that really old outlets used captive ball bearings and coil springs for the detent, but today it is done with a bump and springy copper contacts.

Keppl8R··on Yahoo Groups Archiving Progress
Also happening with RootsWeb Mailing Lists!

Beginning March 2nd, 2020 the Mailing Lists functionality on RootsWeb will be discontinued. Users will no longer be able to send outgoing emails or accept incoming emails. Additionally, administration tools will no longer be available to list administrators and mailing lists will be put into an archival state. Administrators may save the email addresses in their list prior to March 2nd. After that, mailing list archives will remain available and searchable on RootsWeb. As an alternative to RootsWeb Mailing Lists, Ancestry message boards are a great option to network with others in the genealogy community. Message boards are available for free with an Ancestry registered account. Thank you for being part of the RootsWeb family and contributing to this community.

Sincerely, The RootsWeb team

Free Free or open source Free?

The main one that is open source is

Improves with every release, but has a learning curve.
