It looks like it is possible to tack[^] with a solar sail. Not exactly a high speed maneuver, from the looks of those diagrams.
There, now we've both been edjamacated

So long as you don't leave the solar system and so long as you don't want to return fast (i.e. fine for machines, not for wetware) you just furl the sails and wait for gravity to bring you home(wards).

that's true going out too.

nope. As shown in the second article Kent linked to you just angle them so that the force of light slows you down. The thing that you need to keep in mind to understand how it works is that a solar sail craft departs planetary orbit and is normally moving in/out in an elliptical orbit around the sun. As a result you can always enlarge/contract the orbit by angling your sail so that the suns light is pushing to speed up/slow down your velocity.

I can't wait for the launch. I just hope it goes better than the last two missions I helped fund. The Planetary Society has been burned twice in a row by crappy Russian rockets (a prior solar sail attempt, and sending a sealed package of bio samples in/out on the Phobos return mission to test the impact of interplanetary radiation on viability); hopefully SpaceX has better luck.

The annual Future of Open Source survey confirms what we all suspected: Open source has won. You know what this means don't you? THIS is the Year of Linux!

Redmondologists decide patches will ship as soon as they're ready, a big change from the practice of the past 12 years. But it was always such a great excuse why you got nothing done on that day

I'm not sure about that, but wasn't Patch Tuesday introduced to avoid the maintainance/deployment mess created by the idea to "ship patches as soon as they're ready"?

Yup. "Those who do not learn from history..." etc. etc.

Yup; it'd need a restartless kernel to minimize the impact. And from what I've read about how Linux is implementing it (patching of running application stacks), it's not something that MS could get away with doing because when it inevitably blows up in the face of some clever sunshines of application developers MS will get 1000% of the blame.
I'm personally unconvinced that the article author is right. Every quote in it I saw could be applied to feature updates only.

Why the myth of the "10X" programmer is so destructive. "I'm just a regular Joe with a regular job"
|
|
|
|
|
I've come to believe that most people, not just programmers, are just a bunch of bunglers, professionally speaking.
How many people are really interested in their work?
How many people strive to be the best at what they do?
Most people are much more interested in being with their families, going fishing, watching 'the game', doing whatever it is they like doing.
And rightly so I say, we are not defined by our jobs!
But then there are those few who either really love their job or are really smart.
They excel in what they do, be that programming, managing, building houses or cleaning desks.
Those people, in my opinion, are those 10x programmers (or whatever profession).
And recent study has shown they can be much more productive than that (a claim I can't back up as I can't find the article anymore...)!
In fact, having a good programmer, a good DBA, a good manager, a good what-have-you can save many, many hours of fixing bugs, performance problems, overtime... And time is money!
There is just no denying that some people are just a lot better at their jobs than others.
And if those people are not assholes about it they can save you a lot of time and money (if they are assholes they'll drag down the team and their supposed added productivity is negated completely).
It's not the 'myth' that's destructive.
It's the expectation that everyone should be that 'superstar'.
In fact, with good management, even the 'regular' people can shine like superstars!
Yes, let's call it the 'myth of bad management' (because most people are bunglers in that profession too ).
If the notion of 'superstars' is destroying your company you've got a much bigger problem than superstars...

There are people inside of Redmond currently working on a Windows cloud client, and when complete, the release will follow the Windows 10 free upgrade president. "If man is still alive, if woman can survive"

With the release of Java 9 slated for September 2016, it’s not too early to start thinking about what the new release will actually do to your code. Filed under: job security

"Right now we’re releasing Windows 10, and because Windows 10 is the last version of Windows, we’re all still working on Windows 10." "The first hit is always free"
Yeah, I use that one a lot, but seems pretty appropriate here (plus, I haven't used it since November)

The Article Says:
WINDOWS ISN'T DEAD, BUT THE IDEA OF VERSION NUMBERS COULD BE
Right, Windows is dead, but it isn't. But version numbers are. Okay, whatever.
