Goldman Sachs Demands Google Unsend One of Its E-mails

zeigerpuppy Re: Email Insecure (346 comments)

Actually email intradomain is relatively secure. If it's send from a gs.com to gs.com address from an internal computer, the email should never leave the building (assuming they have their SMTP server onsite). This is one of the main advantages of a federated protocol

Solar-Powered Electrochemical Cell Used To Produce Formic Acid From CO2

zeigerpuppy Re:Amazing technology (133 comments)

I agree, carbon sequestration technology requires use of the end products in ways that don't return the CO2 to the carbon cycle (or at least slow down turnover). This is no different for any technology (including tree biotech). However, there is no technology that I have seen that is more efficient in life-cycle analysis than the well considered use of biological methods of CO2 harvesting. Water use is also a key requirement of other CO2 harvesting techniques so not a specific negative of the use of plants.

Solar-Powered Electrochemical Cell Used To Produce Formic Acid From CO2

zeigerpuppy Re:Amazing technology (133 comments)

It's lucky that we have so many different trees (and plants in general) that given a start can colonise almost any environment. The 6% figure comes from Zhu, Ort, and Long 2008, see this post for some discussion: http://biology.stackexchange.c...

Solar-Powered Electrochemical Cell Used To Produce Formic Acid From CO2

zeigerpuppy Re:Amazing technology (133 comments)

While the solar illumination -> biomass conversion is only about 6%, one needs to consider the whole life cycle of the technology.
Trees have a number of difficult to beat efficiencies.
Firstly, they do not require manufacturing (which uses a significant amount of energy and materials). Secondly, they do not require transport to site. They also self replicate which is a huge bonus that other technologies cannot currently compete with. Also, trees produce a variety of highly useful materials. Yes there is some need to refine these end products.
To your second point, one does not want to use wood as fuel if the aim is to harvest CO2. Use as a building material, however is ideal and also saves more CO2 as concrete or steel are much more carbon intensive.
If you look at the whole life cycle of a CO2 removal system, it is hard to beat, but please post back some figures if you think there is a tech with better efficiency considering these factors.

Solar-Powered Electrochemical Cell Used To Produce Formic Acid From CO2

zeigerpuppy Amazing technology (133 comments)

There is an amazing piece of technology that harnesses sunlight, converts water and CO2 into complex carbohydrates, useful proteins and even medicines. It self propagates and can be installed in a variety of environments. There is an existing harvesting infrastructure and it also produces an essential building material. It is known as trees.

US Officials Cut Estimate of Recoverable Monterey Shale Oil By 96%

zeigerpuppy anyone who believed the bull (411 comments)

Should have had a look at the production curves, tight, shale and fracked sources have very rapid decline. It's pretty much the definition of unsustainable.

Can Thunderbolt Survive USB SuperSpeed+?

Interesting, which device are you using to use the FireWire interface? I would love a programmable arduino like device with faster io for low latency signal acquisition.

Australia OKs Dumping Dredge Waste In Barrier Reef

zeigerpuppy Re: By reef... (277 comments)

Actually, dredge spoil contains fine particles that form a suspension in the water column. They can move a great distance. The main issue here however is the impact of facilitating the burning of more coal. Ocean acidification (from carbon dioxide dissolved/converted to carbonic acid) is a major threat to the reef as coral cannot lay down limestone in acidic waters. The coral has also experienced massive dieback since the 1960s due to rising water temperature, high nutrient sediment from local cane fields and the impact of crown of thorns star fish. Many marine biologists argue that it is already beyond tipping point. Our blind, stupid, climate denying government doesn't seem to believe in the ample evidence. Short sighted politics and crony capitalism is destroying the very resources that our future prosperity is based upon, not very rational economics.

Revolutionary Scuba Mask Creates Breathable Oxygen Underwater On Its Own

zeigerpuppy concept not engineered device (375 comments)

just in case you were wondering, this is not a real device. Interesting concept but this would need to be considerably more bulky to drive enough water through the filters. About 200litres of water needs to be flowed through the device per minute. For a working prototype for comparison see: http://www.youtube.com/watch?v=D23HLDZvX2w which works with a compressor. The poster should make it clear that the device mentioned is not an actual device, nor likely to be feasible without a relatively large pump and power supply.

Bill Nye To Debate Creationist Museum Founder Ken Ham

zeigerpuppy Re: Excercise in Futility (611 comments)

Indeed, having debated the truth of scripture at length with Christians, I found the "agree until they see the flaws themselves" approach very effective. Releasing people from the chains of these repressive idiologies is possible and worthwhile but don't expect success to begin with!

zeigerpuppy Re: Waste of Time (611 comments)

Not really convinced by the religion doing more good argument either. Lot of wars and division based on religion. And even more hiding their heads in the sand and allowing corrupt leaders to subvert them.

I'm certainly not religious but I do find it interesting that Genesis is actually a pretty good description of creation I you take the days as epochs.

Bill Nye To Debate Creationist Museum Founder Ken Ham

zeigerpuppy Re: Bad call (611 comments)

You ate creating straw men on both sides, resulting in a false dichotomy. An idea of God may be compatible with evolution, it's just that a church preaching incompatibility has painted themselves into a corner. Many scientists believe in a mysterious, unexplained order to the universe, some even call it God. But denying the evidence that is right in front of you is narrow minded to say the least. Don't get dragged into us vs them arguments, the truth will set you free.

Just to clarify, Kune is very open with their code, it's Rizzoma who do not publish theirs, my article was a little unclear on this.

Ask Slashdot: Best way to implement Wave protocol self hosted?

zeigerpuppy zeigerpuppy writes  |  about 8 months ago

zeigerpuppy (607730) writes "It's time to revisit Wave, or is it? I have been looking to implement a Wave installation on my server for private group collaboration. However, all evolutions of Wave seem to be closed-source or experiencing minimal development. I was excited about Kune, but its development looks stalled and despite Rizzoma claiming to be Open-Source, their code is nowhere to be found! Wave-in-a-box looks dead. So Slashdotters, do any of you have a working self-hosted wave implementation?"
