Canaries As Poisonous Gas Detectors
n the late 1890s, [John] Haldane began experimenting on small animals like white mice and canaries [to detect carbon monoxide]. Small animals have faster metabolism rate, and hence show the effects of carbon monoxide poisoning much earlier even in the presence of small quantities of the noxious gas. Canaries are especially good at detecting toxins in the air because of their specialized respiratory system.

This computer makes no noise when it starts up. It makes no noise when it shuts down. It makes no noise when it idles. It makes no noise when it’s under heavy load. It makes no noise when it’s reading or writing data. It can’t be heard in a regular room during the day. It can’t be heard in a completely quiet house in the middle of the night. It can’t be heard from 1m away. It can’t be heard from 1cm away. It can’t be heard — period. It’s taken nearly 30 years to reach this point, but I’ve finally arrived. The journey is over and it feels great. If you are after a silent — not just quiet, but silent — daily driver, then I strongly recommend a passively-cooled case, heat pipes and solid state drives. Eliminate the moving parts (e.g. fans, HDDs) and you eliminate the noise — it’s not that complicated. It also doesn’t need to be really expensive (my system requirements were not ‘average’ so please don’t infer from this post that all DB4-based systems are as expensive). Silence (and a perfectly respectable computer) can easily be had for half the price.

Tracking Firm LocationSmart Leaked Location Data for Customers of All Major U.S. Mobile Carriers Without Consent in Real Time Via Its Web Site
LocationSmart, a U.S. based company that acts as an aggregator of real-time data about the precise location of mobile phone devices, has been leaking this information to anyone via a buggy component of its Web site — without the need for any password or other form of authentication or authorization — KrebsOnSecurity has learned. The company took the vulnerable service offline early this afternoon after being contacted by KrebsOnSecurity, which verified that it could be used to reveal the location of any AT&T, Sprint, T-Mobile or Verizon phone in the United States to an accuracy of within a few hundred yards.

Bitcoin’s energy use got studied, and you libertarian nerds look even worse than usual | Grist
This is awful. What a waste:
Bitcoin’s energy footprint has more than doubled since Grist first wrote about it six months ago. It’s expected to double again by the end of the year, according to a new peer-reviewed study out Wednesday. And if that happens, bitcoin would be gobbling up 0.5 percent of the world’s electricity, about as much as the Netherlands. That’s a troubling trajectory, especially for a world that should be working overtime to root out energy waste and fight climate change. By late next year, bitcoin could be consuming more electricity than all the world’s solar panels currently produce — about 1.8 percent of global electricity, according to a simple extrapolation of the study’s predictions. That would effectively erase decades of progress on renewable energy.
