Yes, you are right, they still have to prove they can safely and economically reuse them. But each time throwing away the main stage including a bunch of very expensive rocket engines is not very scaleable either. And agreed, the Space Shuttle's cost/performance is hard to judge, still they flew 135 missions using 4/5 vehicles, making important things possible in space. But it sadly enough did not end well. It is fair to say that space is pretty hard. > Hilaire > > -- > Dr. Geo > http://drgeo.eu > http://google.com/+DrgeoEu > > >

absolutely phenomenal landing, I did not even see it coming that was blazzing fast. My mind was blown thanks for sharing. SpaceX made history once more . Mars here we come, lets send Pharo to mars too :D On Tue, Dec 22, 2015 at 3:03 PM Sven Van Caekenberghe <sven(a)stfx.eu> wrote: > This is a really great achievement: SpaceX successfully launched a rocket > and deployed 11 satellites after failing earlier this year.

How to create a 16x16 icon from a .png file?

by Alexandre Bergel

Hi! A couple of month ago the following expression was working: ThemeIcons new createIconMethodsFromFile: 'cube' directory: '/Users/alexandrebergel/Desktop/cubeâ Now it does not. How can I import .png files in Pharo? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

This is a really great achievement: SpaceX successfully launched a rocket and deployed 11 satellites after failing earlier this year. But best of all, they landed the first stage back on earth!

Re: [Pharo-dev] Object graph stream/visitor implementation?

by Mariano Martinez Peck

Denis, The DeepTraverser was a little easy hack I shared years ago to Tudor Girba which he then (improved it?) put it in Moose. While it works is still very limited. You can give it a try. And if not, please spend some time checking the graph traverser we have in Fuel. I suspect it could be easily adapted for custom code, but I am not sure ;) Basically, check FLAnalysis >> run, which has a stack and starts the trace via #mapAndTrace: Cheers, On Tue, Dec 22, 2015 at 6:20 AM, Denis Kudriashov <dionisiydk(a)gmail.com> wrote: > I found this: http://smalltalkhub.com/#!/~Moose/DeepTraverser > > 2015-12-22 10:05 GMT+01:00 Marcus Denker <marcus.denker(a)inria.fr>: > >> >> > On 22 Dec 2015, at 09:46, Denis Kudriashov <dionisiydk(a)gmail.com> >> wrote: >> > >> > Hello. >> > >> > Do we have way to traverse object graph? >> > >> > I want stream which iterate object graph through instance variables >> with knowledge about path at every step. >> > >> > Maybe Fuel has classes for this ? >> > >> >> yes, I think so.. there is #fuelAccept:, but I am not sure how general it >> is. >> >> I remember that Doru did some object graph iteration experiments, too? >> (I canât find it). >> >> But I think we should actually add a general âobject graph iteratorâ to >> the reflective >> features of the language.

Re: [Pharo-dev] VM error in Arch Linux

by Ben Coman

You just happen to coincide with a transition point from V3 system to new Spur system, which gets us ready for native 64-bit. Just as a point of experiment, try Pharo build 50495 rather than (presumably) Pharo-latest. Then look at upgrading PharoLauncher as others described.
