gerbal··on Nordstrom's robots.txt
Google indexes pages that link to those pages, but can't index the pages themselves. The PageRank algorithm still sees inbound links to unindexable pages.

The Cuba embargo has not been lifted, restrictions have just been loosened a bit.
gerbal··on 3D Printer Shootout – $600 Printrbot vs. $20,000 UPrint SE Plus
given how shit the MakerBot product line got after the Stratasys acquisition, I'm not in the least surprised. (Cleaning a clogged print-head on a MakerBot Mini voids the warranty).

Fortunately, there are lots of hardware solutions to that problem.

gerbal··on America’s new aristocracy
That's not an especially compelling argument. The Top 10% hold more than 77% of the wealth in the United States [1, 2]. And are much more efficient at converting short-term income into long term wealth than the lower 90% [2].

gerbal··on The Failure of a Past Basic Income Guarantee, the Speenhamland System
Though, that a system like this emerged in another period of dramatic and unprecedented change suggests analogy to today.
gerbal··on US Senate Report on CIA Detention and Interrogation Program
People will say anything to get torture to stop. The interrogators will get the information they want, but they will get so much more bad information made up on the spot to stop the suffering, it's impossible to distinguish between actual intel and the subject telling the interrogator what they want to hear.

It gets even worse when the subject doesn't actually know anything useful. Waterboard most people and they will confess to anything they think will make it stop.

gerbal··on No value: Investing, CEO pay and the economy
The nature of ownership has shifted from a long term shared investment in an enterprise, to a short-term investment expecting immediate returns in the next quarter.
gerbal··on Why batteries both thrill and terrify the U.S. utility industry
I think it's that power companies depend on a very broad customer base to support their substantial capital investments. When you start removing a small portion of customers the cost of power to everyone else starts going up. And if those customers aren't consistently off-grid, i.e. they still need grid power sometimes, that can actually raise power costs.

Increasing generation capacity to meet demand spikes is expensive, and requires having large, expensive power stations waiting at the ready, just costing money.

gerbal··on The SSD Endurance Experiment: Two petabytes
So, we know these SSDs will survive an ungodly amount of read-writes. Is there a way to test how they will survive as archival media?

Presumably the major cause of data degradation in archival time-scales is bit-rot from either component failure or media corruption. What are the sources of bit-rot and component failure? Can they be accelerated to provide a rough benchmark for component failure over longer time-scales?

gerbal··on Hackers with Apparent Investment Banking Background Target Biotech
Given the track record of Investment Banks and massive felonies and market manipulation/rigging over the past several years, It's very easy to assume this sort of action was taken by current or former employees of a large Investment Bank.

gerbal··on Study identifies protein which improves synaptic plasticity in animal models
Terrible title. Should be something like "Study identifies protein which improves synaptic plasticity in animal models"
gerbal··on Berlin’s digital exiles: where tech activists go to escape the NSA
Berlin has a lot of vacant or underutilized housing stock compared to other cities. I expect we'll see gentrification like we've seen in NYC, but not SF, or Vancouver style housing booms. I.e. neighborhoods get popular and get expensive, driving the poor, aspirational types to cheaper neighborhoods.

gerbal··on Audacious Plan to Make Electricity as Easy as WiFi
Given that the patent followed a prototype, it has to in some way resemble the final tech.

The fact remains that Ultrasound is not an efficient mode of energy transmission [1]. Wireless induction is almost certainly more efficient over the same distances. And ultrasound is a potential nuisance and hazard to wildlife and pets in way EM broadcasts simply aren't.

IIRC, most of the flaws of bitcoin are in it's architecture as a Currency. A well designer currency is an efficient medium for the exchange of good and services. Ideally, a currency's utility is how easily and fluidly it can be spent. BitCoin does OK on these metrics.

But where Bitcoin falls down is in the long term model of currencies. Currencies should only be a medium of exchange, not a long term investment vehicle. We want people to spend or invest money in useful things rather than hoard money. Bitcoins deflationary model encourages hoarding, which in turn diminishes the amount of currency in active circulation, resulting in a sub-optimal medium of exchange.

For selling Snake Oil to foolish investors?
gerbal··on Audacious Plan to Make Electricity as Easy as WiFi
The patent application[1] lists the transmission frequency as 40-60kHz, a high frequency. Humans typically hear up to around 20kHz, dogs 44kHz, cats 79kHz. Not Low frequencies.

A directed, concentrated, high decibel volume, in the 40-60kHz range is not the sort of thing found naturally 'all of the time.' As other posters have mentioned, transmitting energy via sound is likely impossible do both safely and at useful amperage. Ultrasound is not safe at high energies even if you can't hear it.

Bounty Source makes it pretty clear the bounties aren't from the project maintainers, and bounties aren't collected or solicited as if they are from or for the project maintainers..

I'm confused to why this project is a good idea. It seems like they are collecting funds on behalf of a third party without that third parties consent and then distributing those funds, again without third parties knowledge or consent.

As much as the project seems to have good intentions, insisting that It's BitCoin, BitCoin is different doesn't mean your product is actually exempt from rules and law. Or that Bitcoin is all that different.

There is no reason someone couldn't build a similar project using traditional currency. But then they would run afoul of the many laws designed to protect depositors, investors, and the financial system writ-large. As someone remarks in TFA, holding the amount of currency on ones balance sheets this project would, if successful, is a terrible idea. It's ripe for fraud and abuse. There is a reason services like Gittip assist in transferring fund, and act as the debiter and depositor.

This whole thing is emblematic of the problems with Bitcoin culture, which seems to think it doesn't have to follow any of the rules. Sorry lads, if Bitcoin is currency, you have to behave like banks and investment firms if you are going to act like banks and investment firms.

gerbal··on Windows 10 will come with a command-line package manager
There are a surprising number of malicious repackages of common FOSS utilities like VLC and 7zip i've seen non-expert Windows users install. It's actually not all that uncommon.

gerbal··on BBC to publish 'right to be forgotten' removals list
The problem in this context is that this right is not being used to allow youthful indiscretions to fade from memory, but to suppress speech that may be in the public interest to protect.
gerbal··on GitHub Student Developer Pack
Cost can be prohibitive for scaling an app from a proof of concept to a working prototype. Especially for something that can't or won't be commercialized later.

For instance, I'm working on a web app to visualize a particular subset of twitter activity. Scaling the database to cope with performance demands may prove challenging on free project tiers.

Students have their own gmail accounts vs having accounts issued by the school, who is then responsible for them in some capacity. There is also a cost per-account in Google Apps for Education.
