[off topic] Jobs at JPMorgan Argentina
by Ramiro Diaz Trepat March 27, 2015

March 27, 2015

Hi there Sorry if this isn't adequate on this list. We are starting an important Smalltalk dev group at JPMorgan Argentina (Buenos Aires). In theory Buenos Aires has an above average population of psychologists and smalltalkers, I don't know if there's any causality in that correlation but we'd like to take advantage of the latter (smalltalkers) at least :) Keen candidates please contact me or put your application here: https://jpmchase.taleo.net/careersection/jobdetail.ftl?job=150021865&lang=e… Cheers! r.

musing on thread immutability
by Ben Coman March 27, 2015

March 27, 2015

Just a random idea that been floating in my head for a few weeks... As I understand it, with Spur we can now have immutable objects. I guess this will help when a functional style programming may be useful (such as background tasks). Newly designed applications might make good use of this, but I am wondering about where you might have a large existing code base (e.g. Squeak/Pharo) and you want to background some small part of the existing code. A great effort would be needed to dig deep into object composition to understand how disparate parts of the system may hold references to object internals several layers down, that may get updated unexpectedly. So I am wondering if instead / or as well as object-immutability it is feasible to get thread-immutability, meaning: * writing to any object state is prevented - which prevents the background thread changing the foreground (UI) state unexpectedly; and/or * reading or writing any object automatically sets its immutability bit - which prevents other unknown threads changing the state the background thread has come to rely on. No doubt pushing any existing single-threaded code into such a background immutable-thread will cause immutablity-write-errors - but the advantage is that such conflicts are brought to light rather than biting you from the shadows. cheers -ben

How to create image morph?
by Yuriy Tymchuk March 27, 2015

March 27, 2015

Hi, I want to create a custom icon for a list or tab. I can create a simple shape morph and add a text to it, but how do I convert it into an image morph or form? And is it ok to build such things with morphs? Uko P.S. I need to change text on image, so static graphic will not work.

stuck SHTextStyler semaphores
by Ben Coman March 27, 2015

March 27, 2015

Probably most people don't look much at Tools > Process Browser. I never did until I doing the delay refactoring to keep track of when the timer event loop was running. I often find several of the following processes stuck on a semaphore... [ sem notNil ifTrue: [ sem wait. view ifNotNil: [ view stylerStyledInBackground: text ] ] ] forkAt: Processor activePriority. So I had a little dig. Now trying to fix this multithreaded code at this late stage has some risk of destabilising things, so I propose the following minimal effective change... [ sem notNil ifTrue: [ (sem waitTimeoutSeconds: 5) ifFalse: [ view ifNotNil: [ view stylerStyledInBackground: text ] ] ] ] forkAt: Processor activePriority. Can anyone more familiar with SHTextStyler than the half hour I've had comment if they foresee any problem with that? cheers -ben
