Re: [Pharo-users] Looking for small boards and tiny computers which can run Pharo

Hi, There are other interesting tiny boards that should fit well with Pharo-IOT (we should of course: https://www.raspberrypi.org/products/raspberry-pi-zero/ <https://www.raspberrypi.org/products/raspberry-pi-zero/> but then, there are many and it should be relatively easy to get running there: beaglebone pocket: https://beagleboard.org/pocket <https://beagleboard.org/pocket> Nanpi Duo: http://www.friendlyarm.com/index.php?route=product/product&path=69&product_… <http://www.friendlyarm.com/index.php?route=product/product&path=69&product_…> CHIP https://getchip.com/pages/chippro or industrial platforms like http://www.variscite.com/variscite-products <http://www.variscite.com/variscite-products> > On 23 Mar 2018, at 20:18, Steven Costiou <steven.costiou(a)kloum.io> wrote: > > Hi, > > thanks for the links :) > > Yes i am still working on this topic, however i chose to focus on Raaspbery Pi. It is quite handy to have an embedded linux to experiment things.

Launcher User Templates

by Sean P. DeNigris

How would I make my own images available via Launcher. Where can I read about this or can you point me to a hook? Thanks! ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Great introduction. I'd seen MetaLinks mentioned in emails, but basically ignored them as I didn't know what they were. Thanks, Marcus!

Re: [Pharo-users] Black screen on Mac OSX

by Christophe Demarey

Hi Hilaire, I think the problem comes from the VM shipped. If the VM is too old, it does not work well on recent distributions. You could try to use the stable VM of Pharo 4 instead and it should work. Christophe > Le 26 mars 2018 Ã 14:19, H.

Re: [Pharo-users] PharoLauncher image loading error

by Stephane Ducasse

And you are on MacOSX? Can you describe what you did? Because with the Launcher you can also open old images and ask it to sort them. You just double click on the left pane on the Pharo6.1(stable) item (as attached?)

Hi, The Pharo Launcher I tried is the newset one from the pharo web site (32bits, P6, MacOSX), When I asked for a 6.1 image, I got this error. May be I did something wrong because it was the 1st time I tried pharolauncher.

Re: [Pharo-users] Why should we not rely on #atEnd?

For regular files, the VM compares the current file position to the length of the file to determine whether the stream is at the end of the file. This works for files where the length is known in advance, but fails for other files, e.g. /dev/urandom, which returns a size of 0, so #atEnd currently and incorrectly returns true. For stdio streams the VM falls back to using the C feof() function. The documentation states that it should only be used to determine if the end of file was reached after reading past the end of the file. A longer description is at: https://stackoverflow.com/questions/12337614/how-feof-works-in-c: I've proposed a patch to the VM that will result in feof() being used for non-regular files like /dev/urandom, which would mean that #atEnd answers correctly. But #atEnd still shouldn't be used as a test while looping over streams. HTH, Alistair
