I hope Bitcoin is more than just a fad because it would provide a really convenient way of harnessing solar energy in space without having to beam it all back to Earth. But this can only happen if Moore's Law slows way down (which is happening) and if mining ASICs hit an efficiency plateau lasting for years (is this happening?).

Currently, it costs about 9MWh per BTC, or about $1000 in electricity per bitcoin to mine on a pretty efficient S9 antminer. S9s currently go for about $2/Watt and require about 100 J/TH and weigh, I don't know, maybe 1kg per kilowatt (or 1000W/kg).

Solar modules are about 30 cents per watt on the spot market, produce about 100W/kg (if weight optimized, i.e. not such a thick aluminum frame). Since all the heat must be dumped into space at the ASIC's operating temperature, radiators are about 100W/kg and probably cost as much as solar modules ($0.30/W) if mass produced.

So 1000W of mining capacity would weigh 21 kg and cost $2000+$300+$300= $2600. To launch 21kg at $100/kg to GSO (this is an incredibly low cost, but could be achieved with SpaceX's or Blue Origin's long-term ITS/BFR or New Armstrong rockets) would cost about $2100. So a total of about $4.7/W.

Assuming the lifetime of that whole thing is about 12 years (a reasonable time for a risk-free doubling of an investment), that's about 12 BTC, or about $47,000 at today's prices, or a factor of 10 return.

(Today's BTC returns ~40 cents per kWh invested, this scheme would break-even at about 4 cents per kWh generated.)

...but:
1) There's a whole bunch of glue, like a network link and spacecraft subsystems that must be included as well as spacecraft processing.

2) Moore's Law in the strict sense is over, but progress still continues.

3) ASIC improvement is possible.

4) We don't have Musk's or Bezos' huge reusable rockets quite yet.

5) If return was this well-proven, you'd likely have a bunch of competition from even cheaper sources of energy.

6) I still think Bitcoin is far too volatile and speculative to justify this kind of investment. Given the reduction in mining rate, if you knew Bitcoin would be able to justify this kind of investment over decades, then you'd probably be better off just buying a bunch of BTC right now and holding it.

But maybe the future of cryptocurrency will eventually enable a less volatile and more proven return, making stuff like this worth investing in. I hope so.
You're exaggerating my point to make it look ridiculous.
This is terrifying as a middle-aged adult contemplating a career change out of academics into tech.
It doesn't matter when the software was released. If the generally accepted lifetime of this software product was say 3 years then every customer is (dare I say) entitled to software that continues to function for at least 3 years after they bought it.

If the company decided that developing the old version isn't worth it then giving them a free upgrade path seems acceptable but selling software that is obsolete a few months after someone buys it reflects poorly on our whole industry.

The 140 character limit was chosen based on sending 8bit SMS messages. If it was chosen from an English speaking viewpoint, they could have chosen to base it on GSM 7bit SMS, which would allow 160 characters.

Was the default SMS 8bit in the US at the time or?

Asian languages would require UCS2 encoded SMS messages, which can contain 70 characters as far as I remember.

My first digital camera was a Kodak DC220 [0] and it ran the Digita operating system. [1] Boot time was in the 20-30 seconds (good for the time) but you would often miss shots. "Spontaneity" wasn't in it's vocabulary. Photos were surprisingly good for a 1 megapixel camera with fixed-focus.

140 characters is an 8 bit SMS message. 160 characters is a 7 bit SMS message.

What went wrong with Visual Basic?

The language was simple enough for beginners but not sophisticated enough to scale for large projects. All too often you would have a project that started in VB as a proof of concept which then extended to become the actual system, and then as that system grew it started to collapse under its own weight. The conversion to the CLR fixed a lot of that, but now it isn't really for beginners anymore.

HTML/CSS/Javascript was botched so badly

That combination is atrocious out-of-the-box. There was no "botching" it, but rather (again) scaling to larger problems showed that the foundation was always made of sand.

I have to say I don't follow the "automation" aspect of what you're saying.

What makes "modern dev" more labor intensive than not "modern dev"?

Well it is, objectively, way broader and deeper than before the web explosion. Even aside from the web aspects - barely anyone did heavy database work back then. And if you had a reasonably firm grasp of one OO language - guess what, you were practically a "rock star" (well before the current usage of the term). You knew something about the differences between the Unix shells, and maybe something about inodes and fsck? Great, here's a "devops" (er, sysadmin) job for you.

Nowadays there's just (conservatively stated) at least an order of magnitude of basic "stuff", much of it conceptually independent from the rest, and a lot of it quickly obsolescing (almost as soon as it "matures") - that one has to have a reasonably firm grasp of, just to move the needle from A to B. Or at least not come off as "fossilized or "enterprisey", when talking to "hot" companies, these days (I've actually had the latter said to me, as a description of me, over the phone - after an interview).

So yes, objectively speaking - it's way more intense.

>The only difference is that these other engineers are motivated to be significantly more thorough about their jobs.

Well, it's a whole ecosystem problem. Most of the places I've worked, security was just supposed to be something you learned and credentialized on your own, and no time or resources were deliberately allocated to it.

In fact, you're likely seen as an underperformer if you slow down to get things right or to refactor bad code. And when software does break, `git blame` tends to accuse the developer that was in the worst position to fix a ship that had begun sinking long ago.

I'm not sure how engineer culpability works in other fields, but surely it's always coincided by bad process and management at which point the whole company is responsible.

> In order to give everyone confidence that the people shown in the Keybase are who they say they are, Keybase encourages users to attest to their identity cryptographically on social media. Keybase is its own social network, but it’s not one for sharing pictures of food or sad status updates. It’s a place for Mary to say “This really is Bill” and for Bill to say “this really is Mary.” With enough attestations like that, it becomes really hard for people to pose as someone they are not.

Doesn’t this sound like a nightmare in terms of social engineering attacks?

It's pretty stupid that Google doesn't allow for any way of getting the keys out of it's 2FA app. Your only transition path is backup/restoring an entire device to a newer one of the same OS.

There's no direct path to migrate from say an iPhone to an Android based phone without manually adding each 2FA entry to the new device.
I think what matters here is how much effort it would have taken to backport the fix to the older version of their software.

If it's trivial then they should be expected to.

> Docker abstract away the logging facilities and the filesystem.

No it does not, it expects stdout and stderr to be used and stores its output in a logfile to be replayed with "docker logs" command.

First solution in issue: mount /dev/log. Does not work when your host system is OS X or Windows, as you don't have access to the VM that Docker internally uses on non-linuxes. Also, on Linux it pollutes the syslog instead of docker log.

Second (the one that refers to a gmane post from 2010) is essentially the same as #1.

Third, rsyslog on host (or in a docker image): does not use docker log facility, and docker link is weird.

Fourth, use the alpine image which has a syslogd: works, maybe, but is subject to changes in the Dockerfile (e.g. when the inner path of haproxy changes). Also I don't touch Alpine images because I can't use the standard Debian/Ubuntu tooling in case there are network/firewall issues that can best be debugged from inside the container by docker exec -it haproxy bash.

The PS3 used the Cell, that was a PowerPC accompanies with 8(?) more specialized cores (in hindsight i dare say they were used like oversized DSPs) on a single die.

The hope was that the PS3 would be a test bed, and that the Cell would be popular in supercomputers. I am not sure if that panned out beyond some images of PS3s being piled into racks.

And the Xbox 360 i think was a 3 core PowerPC design.

Looking back at it i wonder if the reason both Sony and Microsoft went with AMD APUs this time round is that AMD brought ATI. And ATI has a history of building graphics hardware for games consoles.

Offering up both parts as a single die would greatly simplify the board design of the new consoles. Never mind that by using x86 for the CPU there would be no cross-complication complications to deal with.

>Silicon Valley likes young people

People get the wrong impression that it's a SV thing.
It's not just SV. Lots of employers (who are themselves age 40+) like to hire 20-somethings.

As one example, there was a reddit thread with a woman in Tennessee trying to start a hot sauce business. In one of her replies, she wrote: "I wanted my company to be young and hip, so I hired young and hip -- okay, ‘hip’ might be subjective, but we’re definitely young."[1]

It was fascinating to watch an honest moment of communication because she later deleted that reply. However, others had already quickly replied to it which left her original comment for prosperity.[1]

In another example, the aides that sit directly adjacent to the President's oval office are traditionally staffed by 20-somethings.[2] There's nothing in the job description that says the gatekeeping work can't be done by senior-citizens but every WH Chief of Staff always wants the high energy of a recent college grad stationed there.

It's not just programming. Whether it's packaging up food sauce in Tennessee or filtering visitors into the President's office in Washington DC, employers want the vibe of a young crew.

You, 6 months from now (or whenever you stop touching this code base), are effectively "another developer".

New developers don't seem to really grasp this until the first time they have to maintain their own old code. I don't think it really hits home until the first time you experience: "What is this? Who wrote this garbage??" runs git blame "..oh, crap."
EDIT - originally compared the last factor to number of grains of sand on Earth squared, but after catching the error above that's much too large.

So how big is the remaining 2x10^12 bombs per seconds?

1.98x10^12 links on Wikipedia
3.04×10^12 trees on Earth in 2015
3.5×10^12 estimated fish in the ocean

So take every link on Wikipedia (or two thirds of the trees on Earth), turn each one into the largest hydrogen bomb ever detonated, and blow them all up every second since the beginning of the universe, and that's how much energy we're talking about.

Thanks again to bonzini for spotting the rather large error!
"There are countless examples where human ingenuity and private entrepreneurship has found frugal solutions to complex problems but none where governments are involved."

Nobody is denying this.

Nobody is saying that 'the government is the only source of innovation or should be managing the economy'.

But there are many industries that would not exist without strategic involvement by state actors.

Again - there are no 'big aircraft makers' in the entire world that are not backed by governments.
I'm pretty sure less people would be rushing into the software engineer profession if they knew it came with the liabilities you described. That would drive up the prices of engineers.. and I'm pretty sure the industry in general doesn't want that.

Don't know about High Sierra issues but Linphone (http://www.linphone.org/) usually works very well. Jitsi Desktop (https://desktop.jitsi.org/) is a decent SIP softphone too but it's really ugly. Both are cross platform and open source, don't know about commercial software.

I wouldn't recommend native SIP softphones anymore, it's a pain to configure and run securely. The best cross platform media stack is the WebRTC functionality in modern browsers, and it usually just works perfectly with a VoIP provider or PBX that has a WebRTC frontend.
