slyfocks··on Fake online stores reveal gamblers' shadow banking system
While I agree that the gaming industry is exploitative, it's unfair to assert that gambling is zero-sum by generalizing all means of gambling as "screens flashing bright lights for a few seconds."

You or I might value a video game more, but some people who gamble actually derive utility from the games themselves (and from a purely scientific standpoint, even a near-miss in gambling results in the release of dopamine [1]).

slyfocks··on Mathematicians looking to make elections in the US more representative
> But ultimately, what political needs would a community of last-name-starts-with-C need?

None, which is why that grouping would only make sense in a society of extremely generic robots.

slyfocks··on Mathematicians looking to make elections in the US more representative
The U.S. is not a monolith–registered Democrats in West Virginia have very different priorities from those in Massachusetts–so geographical boundaries actually serve a purpose in electing a representative who is (ideally) aware of local needs and committed to fighting for them.

In contrast, those with a common birthday or name have no distinguishable political desires in aggregate, so the likely result would be 538 generic congress members.

Furthermore, if we assume people exhibit a bias toward candidates from their home state (they do, on average), grouping by birthday or last name is actually a net negative choice since it would likely result in overrepresenation of Californians in congress (assuming first-past-the-post).

This is not well-written nor is it particularly relevant to anything “hacker-ish.” Has the bar for notability been lowered to content simply having decent graphic design?
slyfocks··on Python For Finance: Algorithmic Trading
This is extremely reckless investment advice.

Active trading, by definition, incurs higher transaction costs than passive investing. Since transaction costs are generally priced per trade, active trading is more costly on a percentage basis for individuals with less capital.

slyfocks··on NBA Highlights – Search for video of NBA plays
Just from a cursory glance at the results, it seems like they're simply providing a naive search on the play-by-play descriptions that the NBA provides (e.g. http://data.nba.net/data/10s/prod/v1/20161212/0021600366_pbp...). No computer vision behind-the-scenes magic, unfortunately.
slyfocks··on Advancing our amazing bet
> If a company's project/product were failing and/or losing money, then investors would have priced the loss into the stock price long ago.

Not necessarily--often, money-losing operations are valued by investors because of their potential to be profitable in the future.

Also, the market is likely more efficient with large companies like Google, Apple et al., but short-term price movements still aren't always rational.

slyfocks··on Bitcoin Was the Top Performing Currency of 2015
Bitcoin's historical volatility (3-10x the currencies listed) makes for an unfair comparison to other currencies--as a currency's volatility increases, so does the probability that it will be an outlier, especially over an extended period (like a year).

Not to mention that currency appreciation is questionably positive and does not warrant the label "top performing."

slyfocks··on First Movie Of An Entire Brain’s Neuronal Activity
Maybe some people don't like following ambiguously-titled links only to discover old news masquerading as something new. Novel idea and totally ridiculous, I know. How could I have been so silly?

Furthermore, my logic is perfectly valid. Scientific research is time-sensitive by nature. If someone were to post an article hailing the discovery of Neptune, while interesting to someone who has been wholly ignorant of Neptune their entire life, it warrants a caveat noting that it's an outdated discovery. And yet under your logic, you would reply: "There's no logical scenario under which someone would find this event notable, but be bummed out because it happened 168 years ago."

slyfocks··on First Movie Of An Entire Brain’s Neuronal Activity
Unfortunately, in the process of sensationalizing the topic, the article strongly suggests that the discovery is breaking news. While a recent revision to the original research was posted on arXiv two weeks ago, the original was published in Nature in September 2013 and the corresponding movie was posted on YouTube 9 months ago as well.

tl;dr: This is old news; temper your expectations.

slyfocks··on The RIAA forced me to shut down a successful website/apps I built in high school
Just a suggestion: I would choose a shorter domain name for the service if the purpose is to create shortened urls. Every character is precious on Twitter et al.
