New Success Story: Sysmocom: Free Software for Mobile Communication

by Marcus Denker

Sysmocom: Free Software for Mobile Communication http://pharo.org/success/Sysmocom "Sysmocom is a leading provider of Free Software Mobile Communication solutions. In 2012 we have started a long term project to develop a complete ASN1, TCAP, MAP, CAP, GSN stack using the Pharo Object Environment. We have decided to use Pharo because of the increased productivity, the great tooling, the live inspection and if necessary modification of a running system to deploy a critical bugfix. Pharo has allowed us to focus on what is important. The stack was used to uncover security and privacy issues inherent to the MAP protocol design in 2014/2015. We have used the stack to build a carrier-grade AuthenticationCenter (AuC) and helped a customer to move their production traffic off a proprietary system to ours. We look forward to move a HomeLocationRegister (HLR) into production this year. said Holger Freyther CEO."

Pharo 5.0 and Garage (DBXTalk)?

by Mark Bratcher

Hello Has anyone installed the database drivers per https://guillep.github.io/DBXTalk/garage/installation.html in Pharo 5.0 successfully? It was a snap in Pharo 4.0. But now that I've moved to Pharo 5.0, I'm getting errors when I try to install the database drivers. First there's a warning that there's an unresolved dependency with TimeStamp (I didn't get this warning in Pharo 4.0). That's quickly followed by an error, "IncompatibleLayoutConflict: Class with ByteLayout cannot be extended as slot". If I click "Proceed" I get a series of numerous other errors. Is Garage compatible with Pharo 5.0? Mark

Re: [Pharo-users] [spotter] How do I get all the pragmas of the system?

by Tudor Girba

Hi, This is not provided because that search is too expensive to happen by default. Take a look at the current implementation: GTSpotter>>spotterForPragmasFor: aStep <spotterOrder: 40> aStep listProcessor allCandidates: [ PragmaType all ]; title: 'Pragmas'; itemName: [ :pragma | pragma keyword ]; filter: GTFilterSubstring; wantsToDisplayOnEmptyQuery: false The last statement says that you have to have a query to start the search. And because it is implemented using as a substring filter, you will only get something when you have a letter in the search. Now, if you want to have a full text search option, for example using string match patterns, you can do this: GTSpotter>>spotterForPragmasFor: aStep <spotterOrder: 40> aStep listProcessor allCandidates: [ PragmaType all ]; title: 'Pragmas'; itemName: [ :pragma | pragma keyword ]; filter: GTFilterStringMatch; wantsToDisplayOnEmptyQuery: false Now, if you type #pragma * you get all pragmas The StringMatch is slower than the Substring and that is why we do not use it by default. We still would like to work on a more unified search strategy, but we did not get to it. Perhaps someone else could propose something.

Re: [Pharo-users] Panama Papers: a case for reproducible research, data activism and frictionless data (powered by Pharo)

by Offray Vladimir Luna CÃ¡rdenas

Thanks GastÃ³n for your interest. I used csv and imported to sqlite, because that's the way the ICIJ released their info and let me query aggregated information in an easy way. I bridge SQLite with Pharo using UDBC and then the choropleth map was made on Roassal. Details are in the blog post ;-). My first attempt was trying to load all nodes in (Entities in the offshore leaks database) in Roassal and query/visualize directly from it, but with over 150k nodes the environment started to lag and doesn't was as responsive as I want for exploring the dataset. That's why I switched quickly to sqlite. I think that this keeps the environment agile and covers a pretty good amount of the cases when you work with tabular data and even some specific graphs could be replicated from the exported CVS files containing the entities and their relationships. My focus was more on accuracy of the visualization, trying to put the rest of the territories in a Roassal map. If you're interested I can put a quick script to run the visualization/notebook in your Moose image. I have not used Neo4J, but there will be a seminar on how it was used in the Panama Papers next Tuesday: http://info.neo4j.com/0526-register.html Cheers, Offray On 20/05/16 16:42, GastÃ³n Dall' Oglio wrote: > Hi.

Hi. Looks good :) Just out of curiosity, what data format you used? csv, sqlite? I am interested in using Neo4j from pharo ( http://smalltalkhub.com/#!/~MasashiUmezawa/Neo4reSt) with a large database, and few days ago and found the ICIJ used Neo4j to relate information. In a few days they will give a webinar: http://info.neo4j.com/05262016-ICIJandPanamaPapersOnDemand_Registration.html A question, you can use Neo4reSt to store data and Pharo/Roassal for display on a more or less friendly way? or there is a lot impedance between graph models? 2016-05-20 13:44 GMT-03:00 Offray Vladimir Luna CÃ¡rdenas < offray.luna(a)mutabit.com>: > Hi, > > I'm glad to share my recent work with Pharo/Roassal in the form of a > minisite[1] and a detailed blog entry[2] arguing about interactive > environments for increasing understanding and participation in data > phenomena: > > [1] http://mutabit.com/repos.fossil/panama-papers/doc/tip/index.html > [2] http://mutabit.com/offray/blog/en/entry/panama-papers-1 > > Using a relatively simple visualization I advocate for this case.
