Siren 9.0 Released

by stephen＠heaveneverywhere.com

Hello all, The Siren system is a general-purpose framework for music and sound composition, processing, performance, and analysis; it is a collection of about 350 classes written in Smalltalk-80 (40 kLOC or so). Siren 9.0 works on VisualWorks Smalltalk (though the bulk has been ported to other dialects as well); Siren supports streaming I/O via OpenSoundControl (OSC), MIDI, and multi-channel audio ports. The Siren release is available via the web from the URL http://FASTLabInc.com/Siren. Siren is a programming framework and tool kit; the intended audience is Smalltalk developers, or users willing to learn Smalltalk in order to write their own applications. The built-in applications are meant as demonstrations of the use of the libraries, rather than as end-user applications. Siren is not a MIDI sequencer, nor a score notation editor, through both of these applications would be easy to implement with the Siren framework. There are several elements to Siren: * the Smoke music representation language (music magnitudes, events, event lists, generators, functions, and sounds); * voices, schedulers and I/O drivers (real-time and file-based voices, sound, score file, OSC, and MIDI I/O); * user interface components for musical applications (UI framework, tools, and widgets); * several built-in applications (editors and browsers for Smoke objects); and * external library interfaces for streaming I/O and DSP math (sound/MIDI I/O, fast FFT, CSL & Loris sound analysis/resynthesis packages ) The best in-depth doc (book chapter) is in, http://FASTLabInc.com/Siren/Doc/SirenBookChapter.pdf The read the demo code workbook (this text), go to, http://FASTLabInc.com/Siren/Siren7.5.Workbook.html or http://FASTLabInc.com/Siren/Siren7.5.Workbook.pdf If you like to read manuals, take a look at, http://FASTLabInc.com/Siren/Manual or watch the detailed Siren demo at, https://vimeo.com/120751122 The links to get Siren9 are, Web site: http://fastlabinc.com/Siren <http://fastlabinc.com/Siren> Package download: http://fastlabinc.com/Siren/Siren_9.0.zip <http://fastlabinc.com/Siren/Siren_9.0.zip> Github repo: https://github.com/stpope/Siren9 <https://github.com/stpope/Siren9> Comments solicited.

Re: [Pharo-users] Uptime

by Vince Refiti

Hello Sven This is the kind of thing I like to see. Gives me more confidence in recommending Pharo to management for production use. Just some things that still concern me though: Why are people surprised at discovering that Pharo is capable of such uptimes? Are people experiencing instability with Pharo in production settings? If so, what kind of instability are people experiencing? Thanks, Vince -----Original Message----- From: Pharo-users <pharo-users-bounces(a)lists.pharo.org> On Behalf Of Sven Van Caekenberghe Sent: Tuesday, 12 May 2020 6:06 PM To: Pharo users <pharo-users(a)lists.pharo.org> Subject: [Pharo-users] Uptime EXTERNAL: Do not click links or open attachments if you do not recognize the sender. Hi, So here is a little anecdote from the real world. I was planning to update the OS on my Linux server, from Ubuntu 18.04 LTS to 20.04 LTS (Long Term Support). This small (Digital Ocean, 1GB RAM, 1 Core) cloud server runs 3 Pharo images with public facing web sites. The machine itself reports: $ uptime 12:37:50 up 530 days, 21:46, 1 user, load average: 0.02, 0.04, 0.01 which means it hasn't been powered down or didn't restart in 530 days. I was surprised to discover that 2 of the Pharo images on that machine did just as well: $ ./repl.sh Connecting to Telnet REPL at locahost:41011 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Neo Console Pharo-7.0+alpha.build.660.sha.2eb9bd2f41e7b0bd8f9f4190906910f83c178ab1 (32 Bit) pharo> get system.uptime 405 days 20 hours 29 minutes pharo> quit Bye! $ ./repl.sh Connecting to Telnet REPL at locahost:41001 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Neo Console Pharo4.0 of 18 March 2013 update 40620 > get system.uptime 530 days 21 hours 44 minutes > quit Bye! So both Pharo 7 and Pharo 4 kept on doing their jobs for a very long time. I think this is a testament to the stability of Pharo and to what is possible.

Re: [Pharo-users] [ANN] What are good reasons to use Smalltalk?

by Richard Sargent

You missed the fact that it makes it easier to communicate with the user community, since it's a "near-English" grammar, and you can easily use a common terminology.

Pharo-Sound

by Russ Whaley

I'm using Pharo 8 stable (64bit) version. I pulled PharoSound from the Catalog and installed. Installed fine, no errors. I went to the comments on the abstract class. Copied the examples to the Playground, ran them - worked fine (although I don't know how to stop the dang PluckedString example!!)... I digress :) I created my own subclass to play specific sounds at certain events in my application. Worked well. A day later - I have no sound in my image at all now. Nothing works. I reinstalled from the Catalog. Ran the code listed in the AbstractSound comments - nothing. I installed a new Pharo 8 stable 64-bit image - pulled PharoSound in, copied the sampe code from AbstractSound comments... and it worked just fine. Any ideas how I can get sound to work again on my original image? For me, it is a real pain to try and migrate all my code over to a new image. It is apparently a character flaw on my part, but it takes me hours to get Git/Iceberg working properly on a new image. (yes, I'm ashamed). I see a new book on the topic, but I had been following that book while it was wip, and Git/Iceberg just whips my butt. But if going to a new image is the solution, I'll try, try again. What do you think? Thanks, Russ -- Russ Whaley whaley.russ(a)gmail.com

Need help with Spec2

by Russ Whaley

I've been using the Spec2-wip.pdf - dated Feb 24, 2020. Is there a newer version? I see something updated about TinyChat - but I don't know how to get that as a pdf, and I doubt TinyChat will address my issues below. I am using SpPresenter - with SpBoxLayouts for labels and buttons. (Pharo 8 stable 64bit) I've been able to figure out (in a very heavy-handed way) how to update the widgets from my model object, and when the UI refreshes (on its own) my data appears. Very good. What I can't seem to understand is, when model updates, there are times I want it to redisplay NOW - for instance, I want to display a 'saved' or 'correct' in a text field, for just a second or two, then allow the normal model update and display. In my example, I have a button with a label (SpPresenter>>newButton) label: 'ABC'. Once my model updates (with the button press action: ), the model is updated and the button label with then be 'DEF' and displays just fine. However, what I'd like to be able to do is to update the button label (or any other widget label) and have it display *immediately*... something like, the button says 'ABC', I press the button, then it says 'Correct!' (pause for a second) and then proceeds with the normal update/redisplay process where the button label then displays 'DEF'. This example is changing a label, but I'd like to also change icons, colors, etc. Clear? So I think my questions are: 1. How do I tell a particular widget to redisplay? 2. And if I can't, how can I tell the window to redisplay. 3. how can I pause (very short - just to let the temporary change be visible for a short time) and then allow the normal processing continue - resetting labels, icons, colors, etc. (I'm using '1 seconds asDelay wait.') 4. and since I've been talking about buttons - SpButtonPresenter - I don't see how to control width and height - all the way up through the hierarchy. If buttons share a layout (SpBoxLayout) row or column, those are all the same size (although I can't seem to control that sizing). Buttons in the next layout>row - are huge. I'd like to be able to set their size specifically (then I can work on making them relative to the extent later). Thanks for listening. -- Russ Whaley whaley.russ(a)gmail.com

git and Pharo new book...

ï»¿ ï»¿I think we just jumped threads. Iâm still getting familiar with using this list. CÃ©drick just posted this I think in response to my exception report: http://forum.world.st/file/t372658/Screen_Shot_2020-05-12_at_2.png > I just had a quick look. This is cool. > I might be missing a use case where I dit a previous fork and I want to use it later in time. I think thatâs nice to cover this use case. Do you sync your fork on github ? From iceberg ? Or maybe no sync is possible ? > > Cheers, > Cedrick > Assuming that is true here is my response: I have not done any syncing yet. I created an empty github repository and was trying to add that to Iceberg when this exception.

Re: [Pharo-users] git and Pharo new book...

by Offray Vladimir Luna CÃ¡rdenas

Hi, This is perfect timing, as I have started to slowly migrate my own repos from SmalltalkHub to aÂ simple, self hosted and self contained Gitea[1] instance, as I don't "commit" to the dangerous logic of hyper centralization that being mainly where everybody is (GitHub, Facebook, Gmail, etc).Â Knowing Iceberg and its rationale is an important step to use improved DVCS for the community and maybe at some point, add support for things like Fossil (and, hopefully be able to help with that). [1] https://gitea.io/ Thanks a lot, Guille, Steph, Allex, and all the community that makes this possible.
