Re: [Pharo-users] What is the difference between GlorpDBX and SqueakDBX?

by Esteban Lorenzano

Hi, DBXTalk is the complete relational database management package. It includes a driver for opendbx and some tools, one of them GlorpDbx. GlorpDbx is a port of Glorp suited to work with dbx driver (but not just that, also the native drivers existing like postgresql and mysql). best, Esteban On Fri, Dec 28, 2012 at 10:51 PM, Frank Church <vfclists(a)gmail.com> wrote: > What is the difference between GlorpDBX and SqueakDBX/DBXTalk and where > does the original Glorp fit in? > > -- > Frank Church > > ======================= > http://devblog.brahmancreations.com

You could probably do what they describe with a Future. See: http://www.squeaksource.com/Futures.html and the blog post linked from that page.

Pharo , Opengl ES 2, Nativeboost and Android 4.1

by dimitris chloupis

So I decided to bite the bullet and start working on Morpheas, which is part of my project Ephestos ( a visual coding enviroment for graphics , music and sound) . Basically Morpheas will be a port of Morphic to OpenGL , probably simplified. So I started learning OpenGL ES 2 , because I was told that basically its possible to write code for both opengl es2 and opengl 3.1 without any major diffirence. And because opengl es 2 is what both Android and iOS use , I started considering what other issues besides opengl i have to handle. For now I am not so much interested on iOS because Apple does not allow for apps that can generate other apps and because Ephestos will be just an extension of pharo its most likely it will get rejected. So I decided to stick with Android for now.Â So the question is how do I use Pharo on Android. I know that CogVM can run on Android and that jenkins has builds for it , my problem is the FFI. I am going to need an FFI to use OpenGL ES , unless I could make Morpheas a pharo plugin which I guess that could work too. But I very beginner with all this and I want your advice on the subject. I assume Nativeboost wont work on an Android device. I own an iPad and I am thinking getting a Samsung Galaxy Note 10.1 tablet.Â http://www.samsung.com/global/microsite/galaxynote/note_10.1/index.html

I link to some related posts below. Regarding sample code... what are you trying to do? The way I commonly use the Transcript is... Transcript crShow: something asString, '---', somethingElse asString. asString might not be the most efficient way, but its simple. Without 'asString', using the comma to concatenate strings often does does not work since non-string classes generally don't understand comma. http://code.google.com/p/pharo/issues/detail?id=3948 http://www.mail-archive.com/pharo-project@lists.gforge.inria.fr/msg51417.ht… http://code.google.com/p/pharo/issues/list?can=1&q=summary%3Atranscript&sor…

I don't know if this has anything to do with your problem, but I often run into hanging output with OSP and usually send... I think it's #setNonBlockingOutput... to the PipeableOSProcess before reading the output. Then IIRC #output should immediately return whatever's currently available, and you can keep looping to get more.

Is the Transcript in Pharo 1.4 different from the one used in the PBE image? It displays ThreadedTranscript when I check its properties and it doesn't seem to hang like the PBE image.

Commands executing locally work okay, but > the ssh ones generally hang. I do this alot in my current project and I have a small little framework around this because IIRC the "problem" is that your call to #output will block until #atEnd. So what you want to do if you do not want to block is to fork off a background process that reads without blocking. This works really well for me, so I run multiple of these in parallell and each is given its own background Process that reads and copies into a WriteStream on a String. So if I ask my "wrapper" for the output it will ask this stream for its contents instead. regards, GÃ¶ran
