Pine64
by John Pfersich Jan. 8, 2016

Jan. 8, 2016

I've pre-ordered a Pine64 SBC. The write up says it's got a "1.2 Ghz Quad-Core ARM Cortex A53 64-Bit Processor. It has 64 and 32 Bit execution states for scalable high performance power â including a NEON Multimedia processing engine." Does anybody have an idea whether the vm for the raspberry pi will work with this new computer? This is what the ARM site says about the A53 processor: As well as running 64-bit applications, the Cortex-A53 seamlessly and efficiently runs legacy ARM 32-bit applications. It is highly scalable, from a single multi-core CPU cluster, to a dual-cluster big.LITTLE CPU subsystem in combination with the Cortex-A72or Cortex-A57 processor, to a multi-cluster enterprise system connected through AMBAÂ® 5 CHI Coherent Interconnecttechnology. Full ARMv8-A support in a small and highly configurable package means that the Cortex-A53 is highly suited to a broad range of mobile, consumer, general purpose, and enterprise applications.

Halo Menu On Spec Tree Node
by Craig Johnson Jan. 6, 2016

Jan. 6, 2016

Hi All, I had an issue - when I opened a Halo on a Spec tree node in the UI and select the menu Icon, I got a DNU message. However if I selected a normal Morph, the menu Icon worked fine. I'm using Pharo 4.0 released version. Fixed this by changing TreeModel>>iconFor to: iconFor: aNode ^ iconBlock value cull: aNode content*s* cull: aNode Craig

[ANN] The next Pharo Sprints (Lille)
by Marcus Denker Jan. 6, 2016

Jan. 6, 2016

Hello, We looked at the calendar and fixed the dates for all public sprints that we will do this year here locally. These are all Fridays: 29 Januar 26 Feb 25 March 29 April 27 May They will be at the Inria Lille, Building B, third floor (RMoD offices). Remotely, you can join us on Slack or the IRC channel #pharo on irc.freenode.net server. During the sprint, we will try to synchronize local and remote Pharo sprinters. One nice idea is to organise local sprints yourself. E.g. over the last sprints we had one in Chile at the same time. Marcus

Re: [Pharo-users] Using Playgrounds as a notepad
by Andy Burnett Jan. 6, 2016

Jan. 6, 2016

Thanks everyone! I completely forgot that I should ctrl+s on the workspace. I think I have just become too used to google docs etc., and it didn't occur to me that I had to save in order to update a model. Right, I now have two ways forward, and they both look useful for different problems. ws := Workspace open Gives me a simple way to paste in text, and do some initial hand editing Clipboard clipboardText Will be great when I know there is a 'clean-up' method that I need to run on e.g. a table I have grabbed from the web. Cheers Andy

OSX el capitan - SIP
by recursive68＠gmail.com Jan. 5, 2016

Jan. 5, 2016

Hi, Thanks for the suggestion, didn't realise you could do that with OSX applications. I've created a wrapper shell script called Pharo in the MacOS folder with the environment set for DYLD_LIBRARY_PATH and renamed the Pharo executable and launched it from the shell script, and it now works correctly and launches as an OSX application from Finder. Thanks

Lawsuit Tracker app
by SaÅ¡a JaniÅ¡ka Jan. 5, 2016

Jan. 5, 2016

Hello, I'm looking how to build GUI app with Pharo and today found out screenshot of Lawsuit Tracker (http://smallworks.eu/web/projects/lawsuit Tracker) which very much resembles 'typical' desktop/business application. The web site says: "It is made using Pharo, Glamour, Magritte and MongoDB." and in my case I'd replace MongoDB with Sqlite3, have need for more grpahical output - something like: http://saravali.de/screenshots.html but wonder about other components and whether they (Glamour/Magritte) are still relevant *today* ? Otoh, today I was re-reading some stuff about Julia language which looks as fine langauge, but it does not fit on one psotcard, although it provides more "classical" way of developing: editor+REPL along with Gtk(.jl) bindings. The language does perform very well, iow. it's quite fast which is good for my project, but it's a bit cumbersome since there is no support to compile end application, while it looks that Pharo has advantage here providing smoother way of deployment (multi-platform wise). Any hint? -- Even if you are considered to be the most sinful of all sinners, when you are situated in the boat of transcendental knowledge you will be able to cross over the ocean of miseries.

Using Playgrounds as a notepad
by Andy Burnett Jan. 5, 2016

Jan. 5, 2016

I often find that I need to do simple manipulations to passages of text, e.g. remove all carriage returns, or extract email addresses etc. Pasting the text into a Playground doesn't work because there is always an apostrophe, or line break or... etc. and the playground complains. Is there a way to tell a Playground to just ignore the text, and give me a handle to its contents, so that I can then do something like playgroundId contents splitOn:Character space. Alternatively, is there another object that would be more appropriate? Playground would be really useful just because it is in the menu, and always available. Cheers Andy

Dolphin Smalltalk open-sourced...
by SaÅ¡a JaniÅ¡ka Jan. 5, 2016

Jan. 5, 2016

...with MIT license, so I wonder if that will have some impact on further development of Pharo? Iirc, Dolphin can produce stand-alone Windows executable, but maybe something else can be utilized as well? Here is the link with:Â http://object-arts.com/gettingstarted.html Sincerely, Gour -- The humble sages, by virtue of true knowledge, see with equal vision a learned and gentle brÄhmana, a cow, an elephant, a dog and a dog-eater.

Determining if a Process is waiting on a Semaphore
by Ben Coman Jan. 5, 2016

Jan. 5, 2016

Looking at at the primitive comment in... Semaphore>>wait "excessSignals>0 ifTrue: [excessSignals := excessSignals-1] ifFalse: [self addLastLink: Processor activeProcess suspend]" I expected/hoped the following... Transcript clear. s := Semaphore new. p := [ Transcript crShow: '1'. s wait. Transcript crShow: '2' ] forkAt: 50. Transcript crShow: p isSuspended. s signal. would produce 1 true 2 but I get 1 false 2 How do I determine from another thread if a Process is waiting on a Semaphore, or even better, waiting on a particular semaphore? cheers -ben
