Red Hat software and services land on Alibaba Cloud

With that in mind, Alibaba Cloud, which is the cloud computing arm of eCommerce giant Alibaba Group Holding Ltd., said today that it’s partnering with the open-source software company Red Hat Inc. The alliance sees Alibaba Cloud join the Red Hat Certified Cloud and Service Provider program, which makes it possible for it to offer a range of popular Red Hat products to its customers. These will include the company’s flagship Red Hat Enterprise Linux platform, which will soon be made available via a pay-as-you-go pricing model in the Alibaba Cloud Marketplace.

Free software log (September 2017)

I said that I was going to start writing these regularly, so I'm going to stick to it, even when the results are rather underwhelming. One of the goals is to make the time for more free software work, and I do better at doing things that I record.

The only piece of free software work for September was that I made rra-c-util compile cleanly with the Clang static analyzer. This was fairly tedious work that mostly involved unconfusing the compiler or converting (semi-intentional) crashes into explicit asserts, but it unblocks using the Clang static analyzer as part of the automated test suite of my other projects that are downstream of rra-c-util.

One of the semantic changes I made was that the vector utilities in rra-c-util (which maintain a resizable array of strings) now always allocate room for at least one string pointer. This wastes a small amount of memory for empty vectors that are never used, but ensures that the strings struct member is always valid. This isn't, strictly speaking, a correctness fix, since all the checks were correct, but after some thought, I decided that humans might have the same problem that the static analyzer had. It's a lot easier to reason about a field that's never NULL. Similarly, the replacement function for a missing reallocarray now does an allocation of size 1 if given a size of 0, just to avoid edge case behavior. (I'm sure the behavior of a realloc with size 0 is defined somewhere in the C standard, but if I have to look it up, I'd rather not make a human reason about it.)

Free Software Efforts (2017W41)

The issue that was preventing the migration of the Tasktools Packaging Team’s mailing list from Alioth to Savannah has now been resolved.

Ana’s chkservice package that I sponsored last week has been ACCEPTED into unstable and since MIGRATED to testing.

How to define a metrics strategy for your community

Data sets are everywhere, and because open source communities produce plenty of information in addition to source code, most community infrastructures require tools to support the software development process. Examples include bug-reporting systems such as Jira and Bugzilla, versioning systems such as Git, and code review tools like Gerrit. Although communication also takes place through these tools, most is done through mailing lists, IRC, supporting systems like Discourse, and even Twitter and other social channels (especially for marketing and announcements). In fact, most open source communities utilize at least five or ten tools, if not more.

4 website maintenance mistakes to avoid

Maintenance is a good idea for every website, but it's a requirement for websites using open source code. The upside of open source is that everyone can participate. The downside is that means keeping up with everyone's changes. Code gets patched, which causes other code to stop working and need patches in turn. Exploits are found and then blocked. Fancy new features are developed, and your users want them. All of this means you need to keep up! The most important weapon to combat these forces is maintenance. Maintenance is a simple process, but there are basic mistakes that many people make at least once. Avoid these and you'll be well on your way to a safer, cleaner website that isn't a huge pain to keep running.

Even if you could do better, are you being paid to rewrite something that's already mostly working? If you're frustrated enough to take it on as a hobby project, is that what you want to spend your weekend on? GitHub is chock full of not-all-that-unique content management systems (CMSes) and static site builders. Most of them are abandoned, clones of more popular systems, or both. Don't be yet another one.
