ui slowness on newly installed ubuntu 13.04 64bit
by Paul DeBruicker June 16, 2013

June 16, 2013

Hi - I've recently installed Pharo 1.4 & 2.0 on a laptop I upgraded to Ubuntu 13.04 and using both Eliot's vm for Pharo 1.4 and the pharovm from the Ubuntu PPA. The UI is incredibly slow with it sometimes taking 1 second to switch windows when they are clicked or > 8 seconds to find the senders/implementors of a method. Is there something I can check to see what the problem may be? cat /proc/cpuinfo shows that the CPU is running at the high frequency. Thanks Paul

Re: [Pharo-users] Configuring where ZnServer serves files

<<< have a look on git https://github.com/SquareBracketAssociates/PharoForTheEnterprise-english I started to convert all the zinc documentation that sven wrote. We can add a new chapter on Zinc Usage. We are working on a format that generates autoamtically PDF and html for the next books. Stef >>> What a cool idea! So, just to be clear, if I wanted to help, all i would have to do is fork the repo, write / improve a section and then issue a pull request? Cheers Andy

recompile a class via menu item in Pharo 2?
by Paul DeBruicker June 15, 2013

June 15, 2013

In earlier versions of Pharo you could choose a refactoring scope and then recompile everything in that scope by choosing the 'recompile' menu item . Is there a way to do the same thing in Pharo 2? Thanks

<<< This should work: (ZnServer defaultOn: 1701) logToTranscript; delegate: ((ZnStaticFileServerDelegate new) prefixFromString: 'apple/macosx'; directory: '/Library/WebServer/Documents' asFileReference; yourself); start. ZnClient new get: 'http://localhost:1701/apple/macosx/'. If there is no index.html in the directory, you'll need to refer to an actual file. >>> Thanks Sven, that's great! And, I am glad I asked, because I wouldn't have worked that out. It seems to me that Zinc is becoming sufficiently powerful that it could do with a section in the collaboractive cookbook. Could someone on this list give me an account? I could start to capture bits and pieces. cheers Andy

Topic search - Learn programming with Smalltalk
by basilmir June 15, 2013

Are there any good books or resources focused on *mainly* Learning Programming. (with Smalltalk would be a great bonus) I'm not looking for yet another class, syntax, other language compare etc... Just one of those books that's filled with real exercises and medium sized programs that you get to actually get to complete and experiment with. *I found these to be of great clarity:* *Smalltalk, Objects and Design by Chamond Liu* (I wish the account example were a little more detailed, and the initial slow pace would extend throughout the book, it tends to accelerate to fast) *Just ordered Discovering Smalltalk by Wilf LaLonde* (I have a feeling it would be on the same level) It would be great if you could recommend such a book, resource. PS. I feel i read a great deal on the subject but never actually completed a piece of software that's even remotely complete, the pieces just don't fit. There is a great deal of "wow" around how you're not supposed to know how the insides of an object works (encapsulation) but without extensive knowledge of the framework how could one create anything of use?! -- View this message in context: http://forum.world.st/Topic-search-Learn-programming-with-Smalltalk-tp46929… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Phaas - anyone interested in setting up Pharo as a Service?

> he, sorry for insist, but cloudfoundry already does that... and is opensource too :) > at ESUG I seen James present it to deploy pharo images... so is viable :) > > cheers, > Esteban > I agree. And, I was really quite optimistic about cloud foundry when it first came out. I particularly like the way you can have a local micro cloud, and then transition to the hosted cloud. My only disappointment was that VMware are not - seemingly - going to offer gemstone as an option on cloudfoundry.com. Building on what Janko said, I think it is really important to join the cloud 'wave'. The question is how might we - collectively - make this happen? I am perfectly happy to go with cloud foundry, or open shift, or any other option if more knowledgeable people can show that X is the way to go. My only requirement is that I don't want to deal with anyone lower than pharo. All OS patches need to be done automagically by the hosting provider. I think cloudfoundry.com and open shift do that, but my understanding of cloudfoundry.org is that this is a 'roll it yourself' solution. Obviously, that would require someone to step up and do that for us. My preference would be for us to create a suitably configured module for one of e platforms, and we can then start getting experience with it. Stephane, is this something that the consortium might take a lead on? My company is happy to pay some of the costs, if this will help. Cheer Andy

How to split or rename Pharo categories with regard to Monticello packages?
by MartinW June 14, 2013

June 14, 2013

Hi, i was looking for best practices on how to split or rename Pharo categories with regard to Monticello packages. Means, when i change category names i have to somehow reflect this in Monticello packages too? I asked on Stackoverflow: http://stackoverflow.com/questions/16981791/how-to-proceed-with-monticello-… http://stackoverflow.com/questions/16981305/how-to-split-a-package-category… but did not get any answers. So i repost the questions here. I found some similar - older - questions on the mailinglists, but was not sure if there were any news on this. /In Pharo 2.0 i started with Classes in one Package/Category (I'm not sure, what is the right term in Pharo at the moment). I have an identically named Monticello package which i contribute to. Now i split the Package/Category: MyPackage becomes: MyPackage-Core MyPackage-AddOns What is the intended way to manage these Packages/Categories with Monticello now? Is there a way to automatically split the Monticello packages accordingly? (I created some mess doing it manually and ended up starting in a new image and manually filing in the classes and then creating new Monticello packages)/ and /After renaming a Package/Category in Pharo 2.0 that is also under version control in a Monticello package of the same name, how to proceed? can i proceed with now renamed packages/categories in a Monticello package with an old, other name? can i rename Monticello packages accordingly with/without keeping the history intact? What i ended up with for the moment is, loading the renamed Package/Category into a fresh image, creating a new Monticello package there and losing the history./ -- View this message in context: http://forum.world.st/How-to-split-or-rename-Pharo-categories-with-regard-t… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I think I've found a bug in String class>>readFrom:. This sentence fails: z := String readFrom: 'Good morning' readStream. I think that the bug is on the first line, saying: ^ self class streamContents:. The 'class' message shouldn't be here, because 'self' itself refers to the String class. Present in Pharo 2.0 and 3.0. Thanks a lot.
