Bitcoin Gold, the Latest Bitcoin Fork, Explained (arstechnica.com) 96

Timothy B. Lee via Ars Technica explains Bitcoin Gold: A new cryptocurrency called Bitcoin Gold is now live on the Internet. It aims to correct what its backers see as a serious flaw in the design of the original Bitcoin. There are hundreds of cryptocurrencies on the Internet, and many of them are derived from Bitcoin in one way or another. But Bitcoin Gold -- like Bitcoin Cash, another Bitcoin spinoff that was created in August -- is different in two important ways. Bitcoin Gold is branding itself as a version of Bitcoin rather than merely new platforms derived from Bitcoin's source code. It has also chosen to retain Bitcoin's transaction history, which means that, if you owned bitcoins before the fork, you now own an equal amount of "gold" bitcoins. While Bitcoin Cash was designed to resolve Bitcoin's capacity crunch with larger blocks, Bitcoin Gold aims to tackle another of Bitcoin's perceived flaws: the increasing centralization of the mining industry that verifies and secures Bitcoin transactions.

The original vision for Bitcoin was that anyone would be able to participate in Bitcoin mining with their personal PCs, earning a bit of extra cash as they helped to support the network. But as Bitcoin became more valuable, people discovered that Bitcoin mining could be done much more efficiently with custom-built application-specific integrated circuits (ASICs). As a result, Bitcoin mining became a specialized and highly concentrated industry. The leading companies in this new industry wield a disproportionate amount of power over the Bitcoin network. Bitcoin Gold aims to dethrone these mining companies by introducing an alternative mining algorithm that's much less susceptible to ASIC-based optimization. In theory, that will allow ordinary Bitcoin Gold users to earn extra cash with their spare computing cycles, just as people could do in the early days of Bitcoin.

Comment Re:Apple is selling the same iPhone for the fourth (Score 1) 211

One of Apple's biggest innovations was partnering with AT&T, Verizon, etc., to sell $1000 computers (iPhones, and to a lesser extent iPads) on an installment plan. People who would never think of doing that for a $600 laptop all of a sudden were buying $900 iPhones that way.

Comment Re:Consensus not always possible (Score 1) 221

You're making the argument that non-standard DRM is superior to standardized DRM because it will result in non-compatible implementations, and "flailing around". I can only assume that because of the lack of a standard and flailing around, that will lead to bad user experiences, and so the media companies will ultimately drop DRM which will lead to a better user experience? Is that the jist of your argument?

This line of reasoning requires you to view a DRM-free experience as superior to one with DRM. That's an ideological argument, not a practical one. End users don't care one way or the other, they only care if it works or not. And as has been evidenced, DRM does work and are used by massive number of people - HBO Go, Amazon Prime, Netflix. Second, it requires you to view the "bad experience with DRM" as not a problem because it leads to "better experience without DRM". There's a whole period in there where "bad experience with DRM" is what end users will be getting. The W3C's primary goal is not to drive ideology, but to improve the web experience via standards. Intentionally failing to standardize on DRM because of ideological concerns is what runs counter to their primary mission. Failing to standardize something that needs standardization because of ideology is what would transform them into a completely different organization, not ignoring consensus.

The one point you make that we can possibly agree on is that we may not need a DRM standard at all, and that several non-compatible implementations are just fine. If the existing stuff is working well enough, then I agree; but then you don't get your DRM-free experience either.

Comment Consensus not always possible (Score 1) 221

Consensus is not always possible for contentious issues. It's a nice ideal to strive for, but there are some issues where consensus cannot be practically reached. Compromise is likewise not always possible either. Those are the times when strong leadership is called for to make a decision, over the well-reasoned objections of some of the members of the body.

As this post nicely describes, DRM is already here, isn't going away, and this whole debate wasn't about whether or not we should have DRM at all. It was about whether or not to standardize something on the web, which is even more of a primary goal of the W3C than reaching consensus.

Comment Re:Tickets will still cost whatever people will pa (Score 1) 67

When demand exceeds supply and prices go up, that is supposed to induce more producers to enter the market (seeing the large profit available in that market) and provide more supply. Remember, low barriers to entry and all that other free market stuff? Well when there's only one act with a limited number of shows (most times just 1), that's impossible. So you have a fixed supply and if the demand isn't met by that fixed supply, that of course leads to prices going up.

As someone else mentioned below, the way some acts solve this problem is by announcing more shows after the first show is sold out, which puts more supply into the market. After all, if demand isn't exhausted with 1 show, more shows at the same venue on subsequent nights (which is quite low marginal cost relative to that first show) will lead to greater profit for the act, and lower prices for the consumers.

Comment Impossibility of access (Score 2) 143

Before encrypted electronic communications, criminals and terrorists had to use things like in-person meetings or unsecure communications methods (like analog telephony) to communicate. These were obviously vulnerable to being listened to for a determined party, but that was simply how it was, there was no other option. Law enforcement could use various human-powered means to target specific individuals or organizations, like tapping a particular phone line and having a human listen to it when it went active, or maybe stake out a particular meeting place with some high-power microphones. For the general non-criminal population, while it was technically possible for the government to listen to everyone all the time, it was realistically impractical because of the vast amount of manpower it would require.

Today we're in the opposite situation. Law enforcement can now get ahold of all electronic communications through various taps, but if criminals and terrorists use the proper technology and best practices, it is *impossible* for law enforcement to know what is being said. (Yes, deep-cover operatives are still possible but are impractical for all but the absolute highest-priority things for reasons of time, risk, and the same old manpower problem).

I don't have a great answer. Anything is either too insecure or seems too vulnerable to corruption. The only thing I've come up with is third-party escrow of encryption keys, but who is the third party and how do we know they aren't corrupt?

FCC Kills Plan To Allow Mobile Phone Conversations On Flights (pcworld.com) 99

An anonymous reader quotes a report from PCWorld: On Monday, the U.S. Federal Communications Commission killed a plan to allow mobile phone calls during commercial airline flights. Since 2013, the FCC and the Federal Aviation Administration have considered allowing airline passengers to talk on the phones during flights, although the FAA also proposed rules requiring airlines to give passengers notice if they planned to allow phone calls. The plan to allow mobile phone calls on flights drew sharp objections from some passengers and flight attendants who had visions of dozens of passengers trying to talk over each other for entire flights. But FCC Chairman Ajit Pai on Monday killed his agency's 2013 proceeding that sought to relax rules governing the use of mobile phones on airplanes. Under the FCC proposal, airlines would have decided if they allowed mobile phone conversations during flights.

The app is nice, but the other really big thing that Uber brings to the table is surge pricing. A surge really does what it is designed to do: gets many more drivers out on the road to match the large demand with more supply. Taxis don't have anything like that. If there aren't enough taxis, you just have to wait.

The Wikipedia summary of this study is horribly worded and one could easily read it as the zinc lozenge having no effect, which is exactly the opposite of the study's conclusion (that zinc does has a positive effect on cold symptoms). The study's purpose was to determine if zinc lozenges only affect/improve symptoms in the pharyngeal region (the throat) since a lozenge is dissolved in the mouth and throat, or if the zinc has an improvement effect in the nasal region as well where it is not directly dissolved. The study showed that zinc *does* improve symptoms in the nasal region. The conclusion that the Wikipedia article is summarizing was that there was no difference in the effect of the zinc treatment depending on anatomical region - the zinc lozenge improved symptoms in both the throat and the nasal region.

'Radioactive Boy Scout' Reportedly Passes Away At Age 39 (harpers.org) 182

A funeral notice quietly appeared on Tributes.com recently, announcing the death of David Charles Hahn. Though no cause of death was provided, when he was 17 Hahn "achieved some notoriety as a teenage Boy Scout with his attempt to build a nuclear reactor in his garden shed," remembers Slashdot reader braindrainbahrain: His "reactor" ended when the EPA declared his backyard as a Superfund cleanup site due to hazardous levels of radiation. His story was captured in a Harper's magazine article, and later the book "The Radioactive Boy Scout" by Ken Silverstein. It was also a Slashdot topic...
Hahn had used materials from household products like lithium batteries, smoke detectors, and old radium clocks, according to Wikipedia, which adds that shortly after Hahn's lab was dismantled, he became an Eagle Scout.

Facebook Says Humans Won't Write Its Trending Topic Descriptions Anymore (recode.net) 76

Following a former Facebook journalist's report that the company's workers routinely suppressed news stories of interest to conservative readers from the social network's Trending Topics section, the company has been in damage control mode. First, the company announced it would tweak its Trending Topics section and revamp how editors find trending stories. Specifically, they will train the human editors who work on Facebook's trending section and abandon several automated tools it used to find and categorize trending news in the past. Most recently, Facebook added political scenarios to its orientation training following the concerns. Now, it appears that Facebook will "end its practice of writing editorial descriptions for topics, replacing them with snippets of text pulled from news stories." Kurt Wagner, writing for Recode: It's been more than three months since Gizmodo first published a story claiming Facebook's human editors were suppressing conservative news content on the site's Trending Topics section. Facebook vehemently denied the report, but has been dealing with the story's aftermath ever since. On Friday, Facebook announced another small but notable change to Trending Topics: Human editors will no longer write the short story descriptions that accompany a trending topic on the site. Instead, Facebook is going to use algorithms to "pull excerpts directly from stories." It is not, however, cutting out humans entirely. In fact, Facebook employees will still select which stories ultimately make it into the trending section. An algorithm will surface popular stories, but Facebook editors will weed out the inappropriate or fake ones. "There are still people involved in this process to ensure that the topics that appear in Trending remain high-quality," the company's blog reads.
