dakoller··on Ask HN: What Are You Working On? (December 2025)
Great idea, I'd appreciate an RSS feed
dakoller··on Ask HN: Did you deliberatively develop any new hobby in recent years?
Yes, playing piano last year. I use the simply piano app and made it a habit to play 10-15mins every weekday.
dakoller··on Ask HN: What are you currently building?
I am working on an AWS <-> Slack integration (https://dev.aws2slack.com/), which allows you to interact with your AWS accounts from inside Slack using CLI commands.

Additionally you get Trusted Advisor checks and CloudTrail event notifications, which you can e.g. use to get alerted on unauthorized API access.

dakoller··on Paymill, The Samwer Stripe Clone, Raises $13M
I use it (even when I cannot compare it to Stripe):

+: - Focus on an easy to use API for payments on websites/backends, - support for subscriptions, - sending money out to you once per week, - a light way to maintain customer data, - due to the technical solution which they choose (token contains payment data) you don't have to worry about PCI and so on on your infrastructure.

Main point is that the setup is super-fast.

dakoller··on Ask HN: OLAP and Reporting that feels like 2012
RE. issue 2) and 3) I just thought that data cubes an open, but standardized format could help - not only in the financial area: I found RDF data cubes ( http://publishing-statistical-data.googlecode.com/svn/trunk/... ) perhaps being a part of the solution there, with the value add that you could easily connect different data source using their semantics.

(liked the "basecamp for analytics" point)

dakoller··on Writing an API for conceptual relationships - looking for feedback
I like the approach too: You may think of using entities along the Linked Data mantra to compare not only by characters, but with the complete meaning of the term. (e.g. compare "Palmyra" with http://dbpedia.org/page/Palmyra ) In the Linked Data world you can use the SKOS vocabulary to define/store relationships like the ones you mentioned. ( http://www.w3.org/2004/02/skos/ ) To ease the task on linguistic checks you may check the WordNet datasource. ( http://wordnet.princeton.edu/ )
dakoller··on AWS Identity and Access Management - Now With Identity Federation
...like the idea and they way how it is implemented.

This could open up even one more door which today stops discussions about cloud computing usage in enterprises. (of course in these companies, which today rely heavily on existing & own IT infrastructures)

dakoller··on Google+ Topical circles?
A good point: today only the Sparks in Google+ bring some light to what can be possible: for me the key enabling social network development through topic related information exchange.
