Comment Re:Denormalize (Score 1) 671

Another of *these* assumptions - that the code will ever be maintained before it reaches end of life.

I'd written code that runs to this day and it's nearly a decade since anyone ever saw the sources.

Yet another is that it's going to be expanded, and so needs to be written in a modular fashion with abstractions for potential expansions.

Data is read from socket, frames are identified in the stream, then decoded, and depending on the content several reactions are undertaken. Four function calls and a switch(). No, I'm not going to implement an event listener system, just because someone imagines we *might* someday receive the data from something else than sockets, that the protocol is changed in unpredictable manner (I define that protocol!), and that someone might (gasp!) need to edit the switch() code, instead of registering handlers for new commands through the API. Twenty lines of code turn into five files by making this more "versatile".

Who gives a fuck? How does this affect anyone at all? I don't know anyone who has or needs anywhere close to this amount if storage.

I can definitely imagine needing the 15TB one in a few years. After being more of a classical literature and music person for most of my life, I've been getting into film. The canon of great films consists of hundreds of titles, at least. In the past you'd have to be lucky to live in a developed country with a well-stocked library, or have a truly massive disposable income to buy all the DVDs yourself. But people today have an incredible opportunity, regardless of their means or location, to educate themselves about this (or any other) art form thanks to torrent communities.

When you're downloading Bluray rips at full quality, where a single film can be 25GB, then storage space starts filling up quickly. One could delete after viewing to save space, but who knows, maybe someday you'll want to watch a particular title again or show it to a friend or loved one, and at that point there might not be any seeders left on the torrent. So, if storage gets cheap enough, then it's worth keeping it all on disk.

Comment Re:Of course not (Score 1) 643

There was an interesting article about Japan's increasing number of abandoned homes due to the contraction of the population. One problem that this brings is that people who do want to live in their ancestral home or move out to the country, may not be able to get utilities provided, because it simply costs too much to maintain utility infrastructure for so few inhabitants.

There is also the issue of finding enough caretakers for the increasing elderly when the workforce is ever smaller. Unwilling to invite mass immigration, Japan has tried to invest in robotics in elderly care, but these efforts might not be enough.

It's not so simple: the initial investment is huge, and the returns are slow. It takes a visionary (like Musk), with a bottomless well of cash (like Tesla Motors) to enter the playfield. There are safer investments with higher and faster returns if one has that kind of money, and wants to multiply it. Without the "vision" it's simply not going to happen - corporations prefer easy, immediate profits over multi-decade investments, and the asian ones are more conservative that way than the western ones.

For this to happen, it takes a special kind of person in a leadership position. This *might* happen, but I don't see any candidate currently.

They have a turing-complete CPU. They have memory and storage. They have input and output devices.

That pretty much sets them as general purpose computers.

Oh, that's not their intended purpose - not what they are marketed at. Overcoming the lockdown may take some work. But you CAN run arbitrary computation on them, even with the lockdown.

Even on IPad, where they paid close attention to disable general computing to a degree where Commodore 64 emulator was banned because it runs Commodore BASIC, you can still load a page that contains:

<textarea id=x></textarea> <input type="button" onclick="eval(document.getElementById('x').value)"/>

and type away your general computation in Javascript.

Note, by the same virtue, a Postscript printer is also a general purpose computer. But yeah, using the right Postscript, people were playing chess against Postscript printer/scanner devices - the printer would print the chessboard with the pieces, the player would draw the move with an arrow, then scan it in, the printer would recognize the move, calculate a response and print it out. So, yeah, that's general purpose computers for you.

Oh, you just didn't hear about them.

There haven't been many *LOUD* wide-scale attacks on these devices.

Their malware tends to stay under the radar and do its thing without drawing attention. It's quite ubiquitous though.

There are apps that run bitcoin mining on your Android phone.

There are apps that cheat on ad revenue, loading ads en masse (and not displaying them, or you'd long uninstall them).

There are quite a few spyware apps.

Due to the lockdown, traditional "viral" spread is limited. In most cases, "trojan horse" technique is employed. Legal, useful apps in the app store, that have a second, clandestine function. Since getting rid of the malware is pretty easy, and malware that can't make its way into some official store will never reach broader victim base, they just stay under the radar, doing their thing without alerting the users to their presence and without being *overly* harmful.

Comment Makework (Score 4, Insightful) 1145

He suggests instead focussing on the neediest people first, possibly by subsidizing jobs programs.

In today's world of increasing automation, how many of those jobs are essentially going to be makework? Or part of marketing efforts that try to convince people they need something frivolous that they don't have? Is the current economic system so inevitable or desirable that those things are preferable to just letting people stay home?

Comment Gibson envisioned a similar thing (Score 1) 50

In his most recent novel The Peripheral , about a near-future America, William Gibson also envisioned one's mobile phone eventually being usable a virtual-reality headset. Since so much functionality (bank cards, photography) is being integrated into the mobile phone, then it seems a safer bet for a company than trying to introduce awkward standalone hardware into the market.

If you're using Tor instead of something like Freenet, you deserve what's coming.

Freenet, where once quantum computing breaks commonly used encryption algorithms, everyone is going to be revealed to be hosting child porn (unwittingly, but still) on their computers. Yeah, sounds like a really worthwhile network. :rolleyes:
