Pharo + VirtualGPU on Parallella
by Sebastian Heidbrink Dec. 2, 2016

Dec. 2, 2016

Hi folks, I dabbled around with the OpenSmalltalkVM and PharoV50 on the Parallella (https://www.parallella.org/) Although most OpenCL samples do currently not work, because of some issues with the esdk on the Parallella, I can at least report that this combination works. It might take some time until I figured the OpenCL errors out. The building of the kernels throws errors due to include path errors.

BioSmalltalk win ...almost
by Serge Stinckwich Dec. 1, 2016

Dec. 1, 2016

Hi Hernan, apparently BioSmalltalk is the faster in the field of Bio* platforms (BioPerl, BioPython, BioJava, ...) and the more trendy: http://www.ijcseonline.org/spl_pub_paper/PID%2023.pdf I would love to believe in that ;-) But if you read carefully the paper, you will found that authors has made a dramatic mistake ... They think that Pharo was the name of BioSmalltalk ... and then they compare with Google Trends, Pharo against BioPerl, BioPython, ... Anyways the statement that BioSmalltalk is the faster is maybe true :-) Hernan did you know this paper ?

Use of -> in Pharo Code
by Bruce Prior Dec. 1, 2016

Dec. 1, 2016

Thanks for the explanation, Sebastian. It led me to look into associations and dictionaries, which led me to page 190 in /Pharo By Example/. The character, ->, is there used in examples. It is described as a message (I assume a binary message). I found -> also in the index under Object. Thanks again. Bruce

Use of -> in Pharo Code
by Bruce Prior Dec. 1, 2016

Dec. 1, 2016

I have been away from smalltalk coding for a while. On returning to the fold, I often see the use of a right arrow in code. Is this something new? Today in a Teapot app example, I saw, Teapot on GET: '/welcome' -> 'Hello World!'; start. What is the arrow for?

UDBCSQLite and the location of the sqlite3 binary
by Offray Vladimir Luna CÃ¡rdenas Dec. 1, 2016

Dec. 1, 2016

Hi, From time to time, we use UDBCSQLite for our workshops and interactive documentation examples and is a pretty good project for bridging the Smalltalk world and the relational database world. A common glitch is locating the binary of sqlite3 for 32 bits and putting it in a place that is available for the VM. I just make this small hack: === UDBCSQLite3Library>>#library Smalltalk os isMacOS ifTrue: [ ^ #sqlite3 ]. Smalltalk os isUnix ifTrue: [ ^ '/usr/lib32/libsqlite3.so']. ^'sqlite3' === and now is working pretty well on my machine. Of course, this only works on Arch 64 bits and its derivates and could change in other Gnu/Linux variants. So, I'm wondering for a better way to make the path to the sqlite binary not hard coded into UDBCSQLite3 and creating some #library: setter that lets the user to setup the sqlite3 location if the file on UDBCSQLite3Library>>#library is non-existent or wrong. I'm sending this to the list, because AFAIK there is no ticketing on STHub to discuss code issues. Cheers, Offray

Pharo 5 and retina displays in 2016?
by Tim Mackinnon Nov. 29, 2016

Nov. 29, 2016

Hi Guys - its been a while since Iâve had a chance to get back into some coding in Smalltalk, and took the plunge again with a new laptop and Pharo 5, however the screen is really blurry? Doing a google search, I can see this same question raised back in 2012, but has there been no progress in this intervening years or has a workaround not been documented for google to find? Or has everyone just got used to it, and I need to hand in there... I have tried using a different font - but not sure what constitutes a true-type font (are these the same as free-type mentioned in the Settings Browser?). Has anyone found a font that makes everything look crisp (I tried Helvetica but its only marginally better). Or is this still the same issue thatâs been hanging around for a long time as its hard to easily fix? Tim
