Before FB had global world domination, a clone called StudiVZ was fairly popular in Germany. It was regarded at least as controversial.


There is no source code either for the WiFi stuff in the ESP8266.


That has yet to be an issue in my experience.


It's been an issue for me. I wanted to make a battery-powered sensor that would only enable the wifi hardware when the sensor had changed (to maximise battery life) - but the closed-source firmware means that's not possible.

Also, some of the SSL support is in the closed-source firmware, and it's incompatible with Mozilla's 'Modern Compatibility' ciphersuite list.

I used the ESP8266 anyway - it's not ideal, but for my application it was the best thing available. There's room for improvement, though.


What does that mean for terraforming? Establish a magnetosphere first so that solar winds don't drag away an atmosphere?


At humantimescales it's a non-issue. Any terraforming effort capable of generating an atmosphere over ~100 years or so could more than compensate for losses to space.

One great idea I heard to make mars more habitable in general is creating a large magnetic field at a Lagrange point between mars and the sun. A sort of "radiation sunshade"


It's important to realize that when it comes to terraforming you have a tradeoff between speed and cost. The notion of producing an atmosphere in a 100 years is borderline magical, but certainly staggeringly expensive in terms of energy input. Your "sunshade" is another example of a quick, but incredibly pricey option.

Most terraforming research tends to be more realistic, and therefore looks at scales of thousands of years for change to take effect, often driven by engineered single-celled organisms in stages.


For those who are interested, I recommend the terraforming​ video by the excellent Isaac Arthur:

I discovered his channel a few weeks ago, and was blown away. He has tons of videos that cover all aspects of humanity's potential future in the stars in great detail, and does a very good job of staying grounded in hard science. It seems like he really knows his stuff. The episodes can be quite long (15 - 60 mins), but definitely worth checking out. I've been slowing making my way through them.


I'm always looking for youtube channels like this, and that's right in the timeframe I look for. Thanks!


My pleasure. Some of the earlier videos from his megastructure series are a little slow, but he has some absolute gems.

So far, I've really liked the video on "Black hole farming at the end of civilization", some of his Fermi paradox episodes, as well as the one on terraforming.

That sounds like it would be massive, or actually maybe not, like a shadow getting bigger the farther it is away from light.

What about the Mars-based idea, that massive wire that wraps around Mars I think.


Why did you get down voted? You're not a popular magazine reiterating some vague plan about using a large wire-magnet to generate what you're talking about?

I don't know, we'd have to get the atmosphere from somewhere, maybe after the magnetosphere is re-established whether artificially or inside Mars, grab asteroids with ice and use that for the atmosphere.


On what time line? NVM, I didn't see other comment. Makes sense.

Seems to me, a process capable of refreshing a livable atmosphere could just be used as needed, given a sufficiently long depletion time line.

Anyone have ideas or info on what that looks like? My mind moves to things like diverting ice from space. Big scale.


Well, to do it all at once you'd need an icy planetoid, but that's not realistic at all. More "realistic" would be a fleet of robot probes designed to steer water ice laden asteroids onto a collision course with Mars. It would be like building up water a snowflake at a time, and it would be touch to manage. If you do it before an atmosphere starts to develop, you'll lose a lot of it. If you start to do it later though, you're going to be kicking up a lot of dust, but maybe that could be put to some use.


For Deutsche Telekom fiber you don't need no special router. Dial in with PPPoE over VLAN 7 similar to VDSL, minus the VDSL modem.

You'd still have to wait for the first block of data (piece in BitTorrent lingo) to complete.


I'd rather have a buffering symbol than an ad.


Nice one! Plus you would not have to download ad.


Why not link the Rust libstd dynamically?


They did in the article

    $ cargo rustc --release -- -C prefer-dynamic 
    $ ls -al target/release/hello
    -rwxrwxr-x 1 lifthrasiir 8831 May 31 21:10 target/release/hello*

I wonder if it's manageable to build a converter to SVG with just XSLT?


append .torrent to any file url
