Garage uses the OpenDBX C language database access library underneath. Looking at https://linuxnetworks.de/doc/index.php?title=OpenDBX/Support, it doesn't look OpenDBX supports DB2. Does the Windows DB2 ODBC driver work? Does Pharo successfully use the ODBC driver to talk to DB2? Pierce

Re: [Pharo-users] Object Persistence

by Manuel Leuenberger

Hi Stef, The Neo4j Cypher queries express a subgraph/path that you want to match in the big graph (nodes and edges with attributes). No fragmentation due to normalization etc., so no joins, itâs more like a regex matcher: MATCH p=(x:PERSON)-[:KNOWS*]->(:PERSON) WHERE x.name = 'John' RETURN p; Will give you the graph of all persons John knows and all the persons they know (transitive closure). You can also combine multiple queries that one processes the result of the other (pipes and filters). See https://neo4j.com/developer/cypher-query-language/ OutOfMemory only happens if your query selects more data (at any point) than you have memory, as the query execution happens entirely in memory, there seems to be no flush do disk. But there are ways to work around this (albeit resulting in uglier partitioned queries). You can see it in action for my KOWALSKI tool, collecting API clients and extracting call graphs: https://youtu.be/zdx28GnoSRQ <https://youtu.be/zdx28GnoSRQ> Cheers, Manuel > On 31 Dec 2017, at 11:19, Stephane Ducasse <stepharo.self(a)gmail.com> wrote: > > Hi manuel > > what kind of queries can we express? > Can be get select node? > Now out of memory is a read falg for me (for moose because we do that > all the time). > > Stef > > > On Tue, Dec 26, 2017 at 10:03 PM, Manuel Leuenberger > <leuenberger(a)inf.unibe.ch> wrote: >> Iâve always liked Neo4j to persist object graphs.

Formatted print for Duration

by Julien

Hello, I do not see how to do a formatted print from a duration. I would like to be able to do something like: String streamContents: [ :s | 90 minutes formatted: âhh:mmâ printOn: s ] The Duration>>#printOn: method prints the ANSI 5.8.2.16 format: [-]D:HH:MM:SS[.S] The Duration>>#printHumanReadableOn: is not printing in the format I want. Am I missing something or such feature does not exist actually?

Re: [Pharo-users] Releasing to Catalog

by Evan Donahue

Ok, that works. Thanks. My last question is about adding a development symbolic version. Can I use my existing BaselineOf class somehow as a baseline from within my ConfigurationOf "<symbolicVersion: #development>" method, or should I define a redundant "baseline: spec" method in the Configuration of the old fashioned way?
