re: man page - It looks like there is no support for man pages from the snap infrastructure. So, there's not much I can do.
The "stable" version of the snap is really old (circa 2023) at this point because I have been shy about bumping it. The candidate and edge versions are more recent and should be more usable.
> but there is no obvious way to exit. I tried Q,q
It's not very responsive during initial indexing, which is something I need to improve. Pressing `q` should work to exit in general, though. Pressing CTRL-C three times in quick succession will force quit it.
It would help to know which version you tried. Things have gotten better over the years.

A man page exists, but only contains basic information. The builtin help text is much more extensive and can be viewed by running:
> `ps` shows 3 processes which would not die with SIGTERM, have to `kill -9`.
Older versions of lnav would use readline for the prompt and had to run it in a separate process because of "reasons". More recent versions have a custom prompt and don't require the extra processes.
Yep, I would say the stiffest competition for lnav is the old tools[1]. I would just hope folks could have an open mind and give "new" things a chance (although lnav has been on github for 17 years).
> At that time lnav basically just kept everything in memory.
lnav has never really kept the contents of files in memory. It does build an index of every line in a file. One exception is that it will decompress small gzip files and keep them in memory as a tradeoff from decompressing on the fly.
The memory consumption has never been a problem for me. So, it's not something I've ever focused on.
Speaking as the author, I too wish it was written in Rust. But, I started it in 2007 when I needed to get practice with C++ for work. At this point, there's so much code in lnav, rewriting would be a long process. There are some sub-components[1] that are written in Rust though.
A new project called logana[2] is written in Rust and is headed in a good direction. Use/contribute to that if you're really interested.
To elaborate on this, lnav (https://lnav.org) is always polling files to check for new data and will load it in automatically. It does not require the user to do anything.
As far as following the tail of the file: if the focused line is at the end of the file, the display will scroll automatically; otherwise, the display will stick to the current position. Also, if there is a search active, matches in the new data will be found and highlighted.
I would say it's a bad UX and not just odd. I can't see any benefit to making it modal. It should just load new data as it becomes available without making the user do anything.
I tend to agree with ProZD's tier list[1] where "Kiki's Delivery Service", "Porco Rosso", and "Totoro" are at S rank. Those might also be a good introduction since they're pretty "normal".
> There's also a new "https boot", which is supposed to be a PXE replacement, but TLS certs have time validity windows, and some clients may not have an RTC, or might have a dead CMOS battery, and those might not boot if the date is wrong.
I think the lack of entropy right after boot can also be a problem for the RNG. But, maybe that has been solved in more modern hardware.
I was working on network-booting servers with iPXE and we got a bug saying that things were working fine until the cluster size went over 4/5 machines. In a larger cluster, machines would not come up from a reboot. I thought QA was just being silly, why would the size of the cluster matter? I took a closer look and, sure enough, was able to reproduce the bug. Basically, the machine would sit there stuck trying to download the boot image over TCP from the server.
After some investigation, it turned out to be related to the heartbeats sent between machines (they were ICMP pings). Since iPXE is a very nice and fancy bootloader, it will happily respond to ICMP pings. Note that, in order to do this, it would do an ARP to find address to send the response to. Unfortunately, the size of the ARP cache was pretty small since this was "embedded" software (take a guess how big the cache was...). Essentially, while iPXE was downloading the image, the address of the image server would get pushed out of the ARP cache by all these heartbeats. Thus, the download would suffer since it had to constantly pause to redo the ARP request. So, things would work with a smaller cluster size since the ARP cache was big enough to keep track of the download server and the peers in the cluster.
I think I "fixed" it by responding to the ICMP using the source MAC address (making sure it wasn't broadcast) rather than doing an ARP.

The flag simply acknowledges that certain people have the right to exist. Extrapolating anything else out of that is you being weird.

It seems to be necessary because you want to "turn the power of the state against you". All because of a rainbow?
> We won the last election.
Did the whole of humanity have an election that I missed? Just because an election at one time and in one place went one way or the other doesn't mean much to something that is global. If you're speaking of the US Election, a certain person didn't even get 50% of the vote. So, I don't see how you act like this is some mandate that means you get to silence other people.

You don't seem sad about this at all.
My small site now sports a flag because it is clear it is needed. Are you going to come after me too?
