Re: [Pharo-dev] Omnibase/Monibase repository removal

by Offray Vladimir Luna CÃ¡rdenas

Hi all, We have been using ReStore[1] as a lightweight approach to data persistence and ODBC handing form Pharo/GT with pretty good results, as can be showcased in our #CandidatosEnDatos (candidates in data) project [1a]. [1] https://github.com/rko281/ReStoreForPharo [1a] https://mutabit.tiddlyhost.com/#CandidatosEnDatos The microwiki is in Spanish, but there are some data storytelling and visualization we did regarding the candidates for the past presidential elections in Colombia (screenshot below and you can zoom them and fine others in the site linked above). We used ReStore as the database backend to store and query around 10 thousand tweets for over a month from all the presidential candidates in Colombia a store them in a SQLite database. Then we made several visualizations and inject them using Norbert's excellent Mustache for Pharo into a LaTeX template to produce the data visualizations as high definition PNGs. ReStore worked more than well, helping us with all the object-relational mapping and migration, with just some desired features we would like to have but any deal breaker and we didn't findÂ any problem with our SQLite backend regarding performance or size of the information we wanted to work with. I know that ReStore has support for other database engines. Unfortunately I had to cancel my participation to this year ESUG, so I wont be able to share more details about this and other projects I was showcasing there. And maybe a project about data storytelling and visualization for civic tech is pretty far away of most use cases where a Object-relational mapper is needed... or maybe not and this combination could work for other people too. I'll be happy to share more details if that the case. Enjoy ESUG and hopefully we will find soon in virtual events or next year in ESUG.

[ANN] Package Formulas

by HernÃ¡n Morales Durand

Hi everyone, I have spent some time creating a new package manager UI for Pharo 10 to simplify package finding and installation. It is a Spec application which introduces a new concept: Package Formulas. These are just annotated methods with an installation expression, so they do not depend on Metacello, Gofer, Pakbot or any other package manager. Some features are: - Package Formulas already includes a predefined set of categorized formulas. - UI allows you to install packages in bulk. - It is simple to create a script from selections. - Scripts can be decorated with pre, post, and wrapper actions. - You can request to list your own or recommended formulas by opening issues from the UI. - Then the package formula will be reviewed to avoid naming conflicts, and to prevent adding broken formulas. - The UI could be used with a custom container of your favorite, validated, isolated or private formulas. - (Currently) it does not automatically collect packages from remote repositories or query on-line servers, however, you can easily jump to browse a selected project homepage. - License is MIT. https://github.com/hernanmd/package-formulas Hope you like it. Best, HernÃ¡n

UK Smalltalk User Group Meeting - 31 August 2022

by Giovanni Corriga

For this month, we'll be welcoming Instantiations' Mariano Martinez Peck and Seth Berman, who will be talking to us about asynchronous programming in Smalltalk. Whether youâre interested in starting a new project or enhancing an existing system, asynchronous programming offers a great way to optimize application speed and help ensure maintainability as complexity increases. Weâll discuss the asynchronous programming approach, why itâs important, and show live demos in the VAST Platform ( https://www.instantiations.com/vast-platform/ ) of how to get started with futures/promises, asynchronous streams/zones, and more! Mariano Martinez Peck ( https://twitter.com/martinezpeck ) is a senior systems engineer specializing in dynamic programming language software. In 2018, he joined Instantiations to further develop the VAST Platform through the addition of new frameworks, libraries and tools, as well as improving the existing code base of VAST. He is active in the Smalltalk development community, and has used his expertise to co-author numerous open source projects. Mariano has a PhD in Computer Science, and his academic research has been published across various international journals. Seth Berman ( https://twitter.com/sethloco78 ) is President & CEO of Instantiations ( https://www.instantiations.com/ ). He leads a dedicated team that tirelessly supports and enhances Instantiations' VAST Platform, while he guides expansion into new software/service areas like IoT, cloud, and edge computing solutions. Before leading Instantiations, Seth joined the company in 2011 as a software engineer working on projects ranging from advanced code editors and cryptography libraries to FFI enhancements and virtual machine implementations. Previously, he worked for the US government in a variety of domains including stochastic simulation, operations research, grid computing, and link analysis. Seth has a B.S. in Computer Science and an M.S. in Software Engineering. This will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/cbklbrydclbgc/ ) to receive the meeting details. Donât forget to bring your laptop and drinks!

Re: Omnibase/Monibase repository removal

by Norbert Hartl

FYI As the license situation around Omnibase is unlikely to change and such a license is not an enabler for collaboration I came to the conclusion that there is no other way than to start a new OO database (what a surprise! :) ) If you are interested or want to see what will happen in the next months you can have a look at https://github.com/ApptiveGrid/Soil <https://github.com/ApptiveGrid/Soil> After half a day of work it can already serialize and partition a simple graph and store it to disk in a way it can be read back even when partitioned. Thanks to having Fuel we do not need to reinvent the wheel and have serialization/materialization done. Of course this is super simple and does not comes close to anything usable but a good start. I've also added a documentation in the github repo to describe the most important parts for me that I will target. Questions, critiques and laughs are appreciated, Norbert > Am 08.08.2022 um 15:18 schrieb Norbert Hartl <norbert(a)hartl.name>: > > To all Omnibase and Monibase users. > > It turned out that neither of those are open source.

Re: Using pharo in a cloud native environment

by Bob Nemec

We use Azure with our GS Seaside app for single sign-on. Once we have the Azure Graph token we then use that token for Graph API calls. Works nicely. I find MS Graph documentation to be excellent, as are all the supporting YouTube videos. Here's a short Seaside summary of the steps we use... 1 - initialRequest: -> redirect toÂ https://login.microsoftonline.com/Â with your Azure application id and redirection URL, which for use is our app URL + ?authenticateÂ 2 - initialRequest: with 'authenticate' -> send request toÂ https://login.microsoftonline.com/Â with the authentication token provided by the MS redirectÂ 3 - extract the Graph access token from the responseÂ 4 - use the Graph access token for Graph web service calls. In our case we useÂ https://graph.microsoft.com/v1.0/meÂ + Bearer <accessToken>Â to get the authenticated user's Graph ID, which we then use to find the application user object.5 - refresh the token before it expires, which is usually under and hour, by checking theÂ expires_in value We've been running this way for a few months now. Next step is to expand our use of MS Graph with Outlook, Teams and SharePoint.Â Hope that helps,Bob Nemec On Friday, August 5, 2022 at 11:39:48 a.m. EDT, Stefan Krecher <stefan.krecher(a)gmail.com> wrote: Hi,every now and thenÂ I get back to smalltalk/ pharo to find out if there's a practical way to use pharo to manage cloud resources, e.g. by calling Azure- or AWS APIs.I know there have been efforts to implement a Smalltalk binding to use the AWS API at least for some of their services but it looks like there's support for only a few, eg S3.I'd love to use pharo to build a seaside app with a nice UI to make calls to Azure and/ or AWS to start/ stop ec2 instances etc.Of course I could create Azure functions that do the API calls and then just call those functions from pharo - but I ask myself if there's a nicer way do do this ...Any recommendations?RegardsStefan

You did say to get a fork, but it wasnât clear whether it was legit to use it. Iâll probably just update the license, and eventually remove the fork.

Re: Omnibase/Monibase repository removal

Vince, Thanks for this clarification. For me it means I can use my fork for the short term. (I can walk to the exit instead of run). Since the license is clearly not MIT, the rug can be pull at whim, so this code canât be a long term solution.
