Thanks for the correction. I just haven't been able to figure out how
much of a "standard" it actually is. Some RFCs (e.g.,
https://tools.ietf.org/html/rfc5233) acknowledge it as existing ("On
email systems that allow for 'subaddressing' or 'detailed
addressing' (e.g., "ken+si...@example.org") ..."), but it doesn't seem
to be a formal standard.

Understood. In this particular case, at least, it will be difficult to do that, since I don't control the page in question - I just have the ability to drop some text / HTML into it. I suppose I could put a link on the page to a page that I do control, and have some type of form / login system there ... Celejar

Well, actually I care about others as well ;)
But my point was that if it takes a human to scrape my email address,
then spammers are less likely to do it, since to scrape emails manually
at scale would be prohibitively expensive, whereas if the address can
be scraped by bots, then they will do it, since the cost of the bot can
be amortized over lots of addresses.

Cloudflare, for example, asserts that: And what is their "source"? Judging by current spam pattern on the email server I administer, cloudflare (and sendgrid, google, MS) are a big contributer to spam by sneaking mail by dnsbl filter.

No, but you don't care about how many other addresses are harvested,

Yes, sadly that boils down to having a competent ISP, and I know that
in some parts of the world there's not much choice. In the UK, we have
three good ISPs, one of which is amazing but expensive. In general, if
you can find an ISP who will provide a fixed IPv4 address at little or
no extra cost, they probably know what they're doing.
It is possible to send through a smarthost, which an ISP may provide,
without worrying about your own address, but you lose one of the
advantages of your own server, of having troubleshooting information
about outgoing emails. ('My message, ID , was accepted by your
server at xx:yy:zz two days ago... what did you do with it?')

I think Dan is right: what he says is "the recommended modern practice". Defense in depth has to be weighted against the annoyance for real users, and sadly it's much easier to tweak a scraper once to handle yet-another-obfuscation-trick than it is for real users to jump through the same hoops (because those users only jump through those hoops once, so they pay the full price rather than spreading the price over millions of pages). >> Train your people to recognize spam and scams. > I'm talking about a small hobby project that I run in my spare time.

I have the feeling that unfortunately the root cause of the initial problem (it works with bsd-mailx but still fails with mailutils, correct?) remains a mystery though. Maybe you would like to help investigating the issue, in which case we could discover and fix a bug, so that the issue doesn't hit anybody else in the future, which is good for the community. If you would like to do that, there are things we can do to investigate, such as enabling msmtp logging with: logfile - Which would allow to see the actual error message. See https://marlam.de/msmtp/msmtp.html#Logging But don't feel obliged to do that. It's OK. I have updated the wiki page with your inputs anyway.

The address at the top of this email was created nearly 23 years ago, and has been used widely around the Net, including several Usenet groups. I get between one and four spams a day in my inbox. As it happens, I put a new CIDR group on my blacklist today, for the first time in perhaps a year. The next best method is a new free mailbox, with collection piped through the anti-spam software of your choice.

More precisely I think to be able to reproduce the behaviour with
4.19.181-1 but not with 4.19.177-1.

This is probably a regression between 4.19.171 and 4.19.181.
There were cifs related changes. a738c93fb1c1 ("cifs: Set
CIFS_MOUNT_USE_PREFIX_PATH flag on setting cifs_sb->prepath.") might
be a candidate.
Can you please report a bug against the kernel?
If you can test a build, please do test with that commit reverted and
see if the issue disappers.

Modern best practice for putting a contact email on the web
Hi, What's the recommended modern best practice for putting a contact email address on the web while avoiding having it scraped by spam / fraud bots? I'm aware of many of the techniques in use, such as the ones discussed here: https://stackoverflow.com/questions/23002711/how-to-show-email-addresses-on-the-website-to-avoid-spams but I don't know how smart the current bots are and which methods are likely to still be effective. I want to use free software, of course, and I want to avoid server side stuff, since I want to put an address on a simple third party web page that I do not control but have the ability to put basic HTML on. I suppose I could use a text-to-image generator (a sort of reverse OCR), like this one: https://www.generateit.net/email-to-image/ but I'd rather find a FLOSS tool to do this, and I'd rather not provide the email address to some random site ;) And actually, I'm not sure this is really such a good solution anyway, since I'd probably have to find somplace to host the image, which is certainly doable, but it adds complications that I'd just as soon avoid. Is character entity substition likely to still work against current bots? http://www.wbwip.com/wbw/emailencoder.html Celejar

My reason for asking is while debian has dosbox dosbox uses only sdl for interface and sdl exposes no accessibility information at all. The dosemu2 package can be used in sdl or in -dumb mode and -dumb mode works well with console screen readers and may also work well with orca.

The thing is that it is usually (almost always in my experience) easier to assign some special meaning to a few, hopefully rarely used characters (preferably in the ASCII character set (rather than some extended character in UTF-8, for example)). The thing is, if you don't have that special meaning assigned to some fairly ordinary characters, you have to create logic in the tool to figure out the same thing that is denoted by that special meaning. Sometimes (rarely, ime) that logic is not too complicated, But, often it is rather complicated (to all of figure out what logic is required, test it, and maintain it). Much easier to give special meaning to a few characters. Could the developer (or you) choose different characters to assign that meaning to -- yes, but you have to pick ones that won't interfere (too much) with things like the work habits of other people. Could you choose extended characters from something like the UTF-8 character set? I suppose so, but, even though UTF-8 is fairly old, it is (1) not used everywhere (does it work on the bash command line, for example), and (2) requires more effort to recognize.

Parallel processing unit cluster for single ffmpeg calls?
Hi folks, I was wondering if I can build a cluster to convert / transcode videos with ffmpeg. There are some workstations standing around here ... and I though maybe it's possible to combine their computing power? To be clear: The task is to work on a single video as fast as possible. I found this, but it's from 2010: http://www.samir.ca/2010/11/23/high-speed-ffmpeg-cluster-encoding-with-python-and-avidemux.html I have no experience in clustering and would be grateful for any useful hint. Thanks, Christoph

device names - so much escaping
Hi all, I use LVM quite a lot. > richard@backup:~$ sudo lvs|wc -l > 140 The trouble is, things like device mapper seem to involve lots of name translations. So the volume I call d-rh-rm1-home (for dirvish backups of /home on rh-rm1 (my (rh) first (1) redmine (rm) server)) on vg-backup0 which is understandably known (to me) as /dev/vg-backup0/d-rh-rm1-home is then known by its alternative name: /dev/mapper/vg--backup0-d--rh--rm1--home because dev mapper seems to need '-' for its own purposes. But then if systemd has a problem with it, I see a log line like this: Apr 5 07:06:25 backup systemd[1]: dev-mapper-vg\x2d\x2dbackup0\x2dd\x2d\x2drh\x2d\x2drm1\x2d\x2dsrv.device: Job dev-mapper-vg\x2d\x2dbackup0\x2dd\x2d\x2drh\x2d\x2drm1\x2d\x2dsrv.device/start failed with result 'timeout'. in my logcheck email. Which is nearly unintelligible. Now I could make the effort to avoid using '-' in my volume names (and mount points, which also get messed up in systemd's reporting). But is this all really necessary? Can't these tools work without assigning special meaning to ordinary characters? (The problem systemd's reporting, of course, is that I must have forgotten to "systemctl daemon-reload" after editing /etc/fstab ... that never used to be needed either.) Grumpily, Richard

De eerste `touch` heeft het bestand aangemaakt en zet create time. Tweede `touch` is voor het filesystem geen reden om te gaan creeren wat al gecreeerd is. crtime wordt door `stat` getoond als 'Birth'.
