That's a good point. One of the properties I typically instrument in queue processing applications is the time delay from when messages were inserted into a queue, until when they have completed being fully processed. The application e

Glad to see writeups and lessons learned about AutoScaling. As a system builder, I think it's a capability that's under-appreciated. My rule of thumb is that essentially every machine fleet benefits from being managed as an AutoSc

If you know exactly where the problem lies, then I agree that in some cases a conference call might not help. However, more often than not, part of the challenge in large-impact outages is figuring out what's going on and where the pro

"Log-structured file system" or "journaling file system" is often how such things are described. The notion being that the primary operation of interest is appending new data records, rather than modifying existing data.

"Individuals and interactions" is not saying "hire good people", although I can see why you could read it that way. I've always understood it to be saying, "Get people together in a room and talk and figure out

There's "Agile", the buzzword that all sorts of advice-givers have capitalized on commercially, and then there's the Agile Manifesto [1]. The Agile Manifesto has merit and is a set of values, not a methodology - it would

The author mentions the Agile Manifesto. It's worth a read, and the concepts it focuses on are somewhat different than the impression that you'd get by reading about Agile in popular blog posts or websites: http://agile

I would like to make it a simple requirement of receiving any public funding. No one is asking for the code to be polished - I would actually rather it was not modified whatsoever from the state in which the research was conducted. The goal

Then I'd be skeptical about those results. Releasing the code allows others to judge the likely accuracy and integrity of the results. A lot of things can go wrong in complex, multi-step computational processes. If care and rigor has n

I totally get that researchers' incentives are not aligned toward publishing it, so no need to explain that further. There are costs and downsides and probably not enough benefit to them. That's fine. Everyone works within their s

If the virtual machine image you prepared works on your machine and not on mine, I'll troubleshoot it and submit a bug to the VM project. It's pretty unlikely, though - that's why virtual machines and more recently operating

Yes, exactly. All I'm asking for is a literal code and data dump. Take a snapshot of the operating environment and publish it. Ideally as a virtual machine or container image, so people don't have to fiddle with dependencies and v

How about a platform centered around Linux containers (or maybe one of several OS containers or VM images), as the repository image? I'm not saying the work is zero now, but maybe we can get there. If a researcher is developing on a pl

In that case, yes: the spreadsheet itself consists of data and analysis over data (aggregations over columns and rows, etc.) so the spreadsheet itself would ideally be version controlled and published. The idea isn't to ask researchers

Reproducibility for the computer scientist means including any code written and data collected or relied on in the scientific publication itself. In practice, getting there from here isn't literally zero work, since some actual human a

Thanks! That's awesome. I have long thought that a platform for scientific publication where code and data are included would be valuable, and I'm glad to learn it exists. Going further, imagine the code is like a container that a

The notions of "strong" and "weak" typing have never been particularly well-defined, but I think my usage is in line with their usual meaning: https://en.wikipedia.org/wiki/Strong_and_weak_typing &g

by jcrites 11y ago
That's a great analogy! However, I do think strongly typed vs. weakly typed has a role in thinking about this, just a different dimension than the one you're describing. Let's say we come across a JSON structure that looks li

That's interesting. I didn't know that about Avro. Does the framework take responsibility for including the schema and defining a format consisting of schema plus data, or is that the responsibility of the application layer? It so

by jcrites 11y ago
What do you mean by they both have self-describing schemas? In order to read or write Avro data, an application needs to possess a schema for that data -- the specific schema that the data was written with, and (when writing) the same schem

Ion's advantage is that it's both strongly-typed with a rich type system, as well as self-describing. Data formats like JSON and XML can be somewhat self-describing, but they aren't always completely. Both tend to need to emb
