Git Repositories browser vs. monticello
by sergio ruiz Jan. 19, 2024

Jan. 19, 2024

In the workspace, I see that Git Repositories browser if the first selection, and Monicello is marked as legacy. The last time I was using Pharo, I think the Git browser was called âIceberg.â Are these the same thing? Have we now made the move to Git as our primary SCM?

Pharo on Raspberry Pi in 2024
by Rob van Lopik Jan. 19, 2024

Jan. 19, 2024

With the new Raspberry Pi 5 (8Gb) I finally got hold of, and the new Raspberry OS (Bookworm 12), I thought it was time to try Pharo again (see Pharo issue #11841 by @astares). I used zero-config with version specification, like 'get.pharo.org/100+vm'. (On pharo.org there are no OBS packages for Bookworm). Using Raspberry Imager I put 64-bits Bookworm on the Pi5. The installs for Pharo 9, 10 and 11 worked OK. Pharo12 does not work because files.pharo.org/get-files/120 does not contain an aarch64-vm. The P12 image does work with the VM downloaded for P11. UI performance is excellent. Next I tried 32-bits Bookworm (Raspberry OS 12) on the Pi5. As there are no recent 32-bits Pharo images (issue #12769) I only tried P9 and P10. Directly using zero-config loads 64-bit Pharo and even explicitly specifying 32-bit (through 'get.pharo.org/32/90+vm') results in a 64-bit download. The reason is, that the Pi loads a 64-bit kernel even when the OS itself is 32-bits. This means the command 'uname -m' that is used by zero-config, returns 'aarch64' instead of 'armv7l'. I will report this on the zero config repo. So I downloaded and unzipped manually.. Pharo 9 works fine. The Pharo 10 image misses Playground in the menu, but ctrl+O+W works. On a Pi 4 (8Gb RAM) with 64-bits Bookworm Pharo 10 is OK. Pharo 11 (with VM 10.0.5 2023-05-05) gives an error: '[ERROR] 2024-01-16 21:37:55.000 sqAllocateMemory (src/memoryUnix.c:160):I cannot find a good memory address starting from: 0x10000000000'. With 32-bits Bookworms it behaves the same as the Pi (i.e. it also loads a 64 bits kernel) Next I tried the same on a Raspberry Pi 3B+ (1Gb memory). For 64-bits the Raspberry Imager default to the Bullseye version (11) . Pharo 10 and 11 complain about a wrong libc.so version and don't work. Using Bookworm ( 64-bit) Pharo 10 runs OK . Pharo 11 does not work, with the same error as on the Pi4 Last I tried the Raspberry Pi Zero 2W (512 Mb RAM, but only â¬20!). First 32-bits Bookworm. Pharo9 works. Pharo10 also with the incomplete latest image. 64-bits Bookworm seems a bit heavy for this board, but it works. Pharo10 runs, more or less. Maybe headless would be quite useful. Pharo11 gives the same memory allocation error as on the Pi 4 and 3B+ Summary: - On the Pi 5 all Pharo 64 bits versions work - On other Pi's only version 9 and 10 work. Pharo11 has a memory allocation error. - Recent 32-bits Pharo images are lacking; especially for the cheap Pi Zero I would really like to see whether 32-bits is more usable.

Troubleshooting ByteArray
by sergio ruiz Jan. 18, 2024

Jan. 18, 2024

Hi, all. I am working on creating a PDF with Artefact (https://github.com/pharo-contributions/Artefact) and am having an issue running the first example. the Example looks like: PDFDocument new add: (PDFPage new add: (PDFTextElement new text: 'Hello'; from: 10mm@10mm)); exportTo: 'test.pdf' asFileReference writeStream. When running this, I get the error: Instance of ByteArray did not understand #isByteString indeed, ByteArray does not have a method called isByteString. I have tried creating a method that returns either true or false (I tried them both), but I have not successfully built the PDF. The method calling isByteString looks like: ZnUTF8Encoder next: count putAll: string startingAt: offset toStream: stream "Write count characters from string starting at offset to stream." "Overwritten for performance reasons - create a fast path for byte strings" string isByteString ifTrue: [ self next: count putAllByteString: string startingAt: offset toStream: stream ] ifFalse: [ super next: count putAll: string startingAt: offset toStream: stream ] I TOTALLY get this. This is a whole bunch of very specific questions. But my ultimate goal is to take a deep dive into stream processing to figure this out.

[ Security ] Accessing private information from Pharo image
by sergio ruiz Jan. 17, 2024

Jan. 17, 2024

Hi, all. One of my projects logs in to Spaces (Digital Oceanâs version of S3). I need to be able access the credentials, but I donât want to store them in the source code, as I will be using Github to store the projects. Is there an accepted way to do this (encryption)? Should I store them on the system as environment variables? is this efficient? thanks! ---- peace, sergio photographer, journalist, visionary Public Key: https://pgp.key-server.io/pks/lookup?op=get&search=0x69B08F58923AB3A2 #BitMessage BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV @sergio_101@mastodon.social https://sergio101.com http://www.codeandmusic.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

GLASS Platform - Docker container?
by sergio ruiz Jan. 17, 2024

Jan. 17, 2024

Hi, all. I used the GLASS platform years ago, and I was thinking it might be a good match for my upcoming projects. The documentation looks to be the same documentation I used back when I started with Seaside. I am wondering if GLASS has been ported to Docker yet. This seems like a natural extension. Thanks! ---- peace, sergio photographer, journalist, visionary Public Key: https://pgp.key-server.io/pks/lookup?op=get&search=0x69B08F58923AB3A2 #BitMessage BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV @sergio_101@mastodon.social https://sergio101.com http://www.codeandmusic.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Document layout with Pharo
by Sergio Ruiz Jan. 15, 2024

Jan. 15, 2024

Hi, all. I am looking to create a newspaper like listing of movie showtimes. Initially, I thought of using imagemagickâs annotate command to generate the output. Thinking further, I thought it might be worthwhile to generate a LaTeX file, and render that to a jpg. Then, I thought there might be a better way to do this natively in smalltalk. Does anyone have any idea how I might generate a document that can be converted to an image with a reasonable amount of control of the layout? Thanks!

Updating objects in the inspector
by sergio ruiz Jan. 15, 2024

Jan. 15, 2024

Hi, all. I have been away from Pharo/Smalltalk for several years, but I am coming back to it now. I am a senior developer, but havenât used smalltalk in any professional projects. I also found that I donât do ANY pet projects for fun anymore, as the current batch of languages/frameworks are not fun. They are effective and all. But not fun. I am starting a bunch of âscratch my own itchâ projects. Iâll be using Pharo as the data store, and maybe more. The thing I really want to do is document the usage of Pharo in my projects, and explain the toolchain, and why i chose each piece. My first project is to take a list of movie events from the local theater and create a listing reminiscent of the newspaper listings we read in the olden days. I have my models set up and figured out, but I have a really simple question. How do i change the value of an instance variable in the inspector. It looks like it should be super simple, but itâs not working. In this case, I am just trying to take the period out of a string. See that attached image.
