Initially I was sure you were talking about my Scoutmaster. (The details diverged in the end.) The expected arrival time for camping trips was always something like 9:59am - that way people would hopefully show up at 9-something or maybe just a few minutes late like 10:10. If the expected arrival time was 10:00, people would interpret it as 10-something and show up at 10:45.

$250k is a respectable amount, but shouldn't it be based on a percentage of their revenue? /s

Most of the Reason article's criticism is of its factual reporting. The JEDI thing is indeed an opinion piece (and it's legitimate to criticize a magazine for its opinion pieces being stupid), but the puberty blocker stuff (not linked directly from the article, but it's at https://www.scientificamerican.com/article/what-are-puberty-... ) was an article, not an opinion piece.

The developer of curl has done an analysis of what percent of his CVEs would have been avoided in a memory safe language. I think the answer was a bare majority.

The issue may be that your filters act as ORs whereas someone might interpret them as ANDs. If I filter for Social+Kids and Culinary, the CBD/space cake ones come up.

Is this basically https://www.ssllabs.com/ssltest/ but for SSH? If so, that is great. In the past, it has been great to point my sysadmin team at that site and say "My goal is get to an A+ on SSLLabs, the site will tell us what settings to tweak to get there" or to tell external stakeholders "SSLLabs gives us an A+, now stop telling me that LetsEncrypt is somehow not good enough". I'd love to have a simple tool I can point at my internal SSH servers and get a single letter grade like that.

I tried this with a Brother HL-L23200 printer and an old raspberry pi, and couldn't get it to work. Seemed like something in the stack was OOM'ing - it worked fine for just a page or two, but when I tried to print a longer document it would crap out. I gave up and now on the rare occasion when I need to print something I carry my laptop over and physically plug in the USB cord like a neanderthal.

The website is mine to modify. I wouldn't go to great lengths to change things to support virtual COM, but if it's just a question of adding a few lines of javascript to listen to virtual COM and map to keypress events that would be possible.

What do you mean by barcode numbers? UPCs? Barcodes can encode many many different things, some of which are internal, some are proprietary datasets you can buy/license for $$$, and so on.

Are you using Chromebooks specifically?

If so, can I ask which barcode scanner(s) you're using which does work? The easiest solution may just be to buy a different scanner.

I did also email the manufacturer - let's see if they have a solution.

Yes, the scanner is operating as a keyboard HID. I'll look into whether virtual COM could work. Will that still let it type into random webapp pages (how I use it now), or does that tie it rigidly to specific applications? (This question is based on this language from the Realinn manual - "9.2 USB virtual COM mode In USB virtual COM mode, the scanner needs to work with driver and serial software.Expected final behavior is that even if you open up another page, the scanned information will show up in the window of serial software. Please let us know if you need to set it to USB virtual COMmode，we will send you the driver."

I assume that Virtual COM works with both USB and bluetooth?

Unrelated barcode question, to take advantage of a technical audience with knowledge in such things:

I have a use case where users are trying to scan 2d Pharmaceutical Product barcodes (https://www.gs1.org/docs/healthcare/GS1_Healthcare_Implement...) containing lot number, expiration date, and so on. We're mostly using Realinn 6200 scanners, some bluetooth some hardwired. In my testing, the FNC1 character gets sent to my Mac as '29', and to the warehouse PCs as '↔'. They also have chromebooks in the warehouse, and as far as I can tell the Chromebooks are just dropping the FNC1 character entirely from the barcodes.

I can not figure out how to program the RL6200 scanners to replace FNC1 with another character - only to add/remove a prefix/suffix.

Is this a known issue? Do I need a different scanner which can be programmed to substitute characters? Throw out the chromebooks in favor of Windows machines?

I last changed my master password in 2019, and it gave me the option to revert to previous password. So it's not just a 30 day thing.

Thanks for the suggestion.

Any suggested starting points for my research? DDG search for "ansible docker-compose" brings up some suggestions like [1] and [2] but I'm curious if you have other suggestions.

And just so I understand how these work together - I'd use Jenkins+ansible to push containers to my servers, I'd run consul within docker as well, and ... would Ansible register services with consul as it pushes them? Do the services need to be modified to speak with consul directly?

I'm considering k8s, but that also means moving services from on-prem to AKS, getting INF to open up the necessary firewall rules to make the services reachable from on-prem, and so on. And as you said, it's definitely days of investigation. I'm not closed to the option.

New comment by mkopinsky in "Nomad vs. Kubernetes"

mkopinsky — Fri, 15 Oct 2021 13:08:22 +0000

So far I've kept things simple, avoided k8s/HashiStack/etc by using docker compose with a simple docker-compose.yml for each server. This has been working well, but I'm starting to feel the pain points - HA requires copy-pasting yaml, I need to specify which services are on each server, and so on.

What's the simplest next step I can take? I'd like something with (close to) the simplicity of docker compose, but ideally being able to specify something like `instances: 2` and being able to route/load-balance to those instances from another service.
