I have not tried runit. s6 is actively maintained; I don't know about runit (on the other hand, runit is in Debian while you must compile s6 yourself). The author of s6 has a (very biased of course) comparison or various supervisors:

I think the big difference between redo and make is that make requires knowledge of dependencies up front, and this is sometimes tricky to get right. "as you can see in default.o.do, you can declare a dependency after building the pr

So what candidates are there? While C may make it possible to write code that avoids timing attacks, a quick glance at [1] shows one must avoid memcmp and array lookups based on secret data, neither of which would be prevented by the compil

I've not heard of slate before. Glancing at the front page, it looks very interesting. I'll definitely take a closer look, thank you.

I have dreamed of a similar thing for a long time... When I worked in a (science research) lab, we had a few Excel files we passed around for performing various calculations. These were great in that my non-computer-fluent boss could use th

I've read the front page of systemd a couple times, but have not dug into the documentation much. Can someone give a tl;dr of what it provides over the (brilliantly designed in my opinion) daemontools, or successors like s6 [1] and run

It's been a while since I was in that field... Typical sintering temperatures are around 1000 to 1300 degC. Usually about 2/3 the melting point of the ceramic; enough to promote ionic motion leading to fusing of the powder in a re

Ceramics can be 3D-printed [1]. The printed product is a paste of ceramic powder + binder that must be sintered (heated so the organic binder burns away and the ceramic particles fuse together into a strong, dense body). The as-printed part

One issue I've run into (which may simply be ignorance) is the time consuming 'bundle install'. For example, I've updated some gems and run 'bundle update' on my development machine. I push that to the CI ser

A fair definition. If they're anything like mine, the hosts probably have unique hostnames but share the remaining 99% of the nginx config. Is that identical portion a "package" or "configuration"? I think there are

What's the difference between a "package" and a "configuration"? At some level, they are both sets of files, so I can imagine a tool handling both, providing the benefit of a common interface. On the other hand, why

This has nothing to do with putting labels in bold or not, unless I misunderstood?

by pmahoney 13y ago
The idea is to keep focus on the data. The labels are reference when exact numbers are needed, but the data trend is king.
