comment How to investigate the cause of a 100% CPU event that lasted for hours?
Disk and memory usage were normal/unaffected during that time as shown in other charts (not pictured). The charts are compiled by a script that runs every 5 minutes installed on the VPS by default by the VPS provider. They report CPU, memory, disk and network usage every 5 minutes. The CPU is the only one that shows an anomaly. I have a daily backup that runs a couple of hours prior to the start of this "event". It seemed to run normally although it did cause a higher server load (but not CPU utilisation) than normal, pointing to a possible I/O congestion issue.

Wish I could ban anyone who writes the phrase "entire volumes have been written on the subject" online without providing any links or examples.

comment Why nginx gzip_http_version defaults to HTTP 1.1
The first sentence has been removed from newer versions of the documentation, so presumably it does now still send the Vary header. But the impossibility of using keep-alive when gzipping on HTTP 1.0 (because the content-length cannot be known prior to output) still exists and there's no way around that. So decide which is worse: HTTP 1.0 clients missing out on gzip, or HTTP 1.0 clients missing out on keep-alive (which often isn't possible for dynamic scripts on HTTP 1.0 anyway).

This setting does not control what HTTP version is used, it controls whether gzip should be disabled for HTTP 1.0 requests.

comment Do you use postfix or qmail and why
I thought that the "weird licensing" was rectified in 2007 when it was donated to public domain. I think the lack of updates is more of a problem than the licensing these days in terms of acceptance by distros.

comment BIND - why duplicate nameserver entries (@ and *)?
Well, assuming this is mainly about wanting to use subdomains per service, like "www" for websites, that's an opinion that the rest of the world is increasingly moving away from, including for example this website (serverfault.com). Relevant discussion also here and here.

comment BIND - why duplicate nameserver entries (@ and *)?
Redirects? You mean a CNAME? That's not possible for a domain that has any other records and not a good idea otherwise. Or do you mean an HTTP redirect? Those are nothing to do with DNS, bind, or zone files.

comment Is NTFS 16 TB volume size limit “real”?
@Massimo that's what people said about 20GB drives once. And they would have said it about 500MB drives once, too. But I am from the future, and I have two 3TB drives, and yes it's impractical to copy 3TB of data but how else are you gonna store 3TB of data?
