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? 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

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
