davemtl··on All my servers have an 8 GB empty file on disk
A way to prevent this is to create a dataset and reserve n amount of space, typically 10-20% and set it read-only.. before the pool gets full. Then when the pool fills up, you can reduce the reservation to be able to clean up files.
davemtl··on Valve's Proton Has Enabled 7000 Windows Games on Linux
EAC (Easy Anti-Cheat) is the main reason why I've not switched from Windows to a full-time Linux desktop. While EAC does include support for Linux[1], it's up to the developer/publisher to enable it.

edit: Included EACs unabbreviated form as well as a link to supported operating systems.

davemtl··on Before buying a NYT subscription, here's what it'll take to cancel it
When I left the UK 11+ years ago, I cancelled Sky, or so I thought. 6 months go by in another country, all my mail was redirected to my parents address in case I missed something. My parents got angry letters from Sky demanding payment, but I had already settled this before I left the country. Well, turns out they cancelled my TV subscription but was still charging me for Sky+ (ability to record). I'm not sure why it wasn't cancelled at the same time, surely when I told them I was moving to a different country as to the reason I was cancelling, I wouldn't need the Sky+ feature.
davemtl··on Changes to LastPass Free
LogMeIn had (and probably still has) a reputation of putting existing features behind a paywall. I have no problem paying for a service if I like it, I was a paid subscriber before LogMeIn and for a year or two after the purchase. Slowly, prices started to rise, features for free users were being put behind a paywall. After many years of recommending LastPass to family and friends, I just couldn't anymore.

A few years ago I switched to Bitwarden after evaluating everything from 1Password, Dashlane, Keeper as well as free/open source applications like Keypass and Password Safe.

Why Bitwarden? It satisfied my need to be able to sync between a handful of devices (Windows desktop/laptop & Android) and replicated features that were previously available in LastPass. In the last three years that I have been a paid subscriber of Bitwarden, the price has not gone up (yet).

davemtl··on Block Facebook Servers
This container is a piece of art. Ever since using this, Facebook no longer has any "Off-Facebook Activity" about me.
davemtl··on Habitat 67, Montreal's 'failed dream'
The "zoo" as you call it, is known as the Biodome. My kids love it.
davemtl··on PfSense Is Closed Source
The FreeBSD implementation of pf is derived from OpenBSD 4.5. It was modified to be capable of running in multi-threaded kernel. The implication of it not being maintained isn't quite right.

pf in FreeBSD is still maintained, but it's not the pf from OpenBSD that everyone knows and loves.

davemtl··on Signal WhatsApp Chats Import
Signal has a method to backup chats, at least on Android. It's under Settings > Chats and media > Chat backup. Baffling if this feature isn't available on iPhone.
davemtl··on foo@bar.com
Indeed. I've owned `invaliddomain.com` for almost 20 years. You'll be surprised how many use it for testing. One morning I woke up to 30,000 e-mails from Sony Japan with PDFs attached of scanned hand-written part orders. Something similar with Boeing sending me backup notifications. I notified each of these companies about their configuration through their official channels, only to be told "no, it's your server doing this" then usually followed up with an e-mail a few weeks later along the lines of "sorry, our bad". So, if you're testing something and using a test domain, use the IANA reserved domains, please. Theses were the days when I was running my own servers. I don't see it as often now as my e-mail is now hosted.
davemtl··on Check if your IP is exposing any ports. If you see 404 page, nothing is exposed
Found my Mumble server, but not Plex or SSH.
davemtl··on Small mail server best current practices
With all the fixes and standards just to send a cute cat GIFs to your friends on Gmail is such a pain in the butt for most self hosters. If you're doing it, great! Keep it up! All the better for you. But for me, using a e-mail hosting provider with a good reputation is preferable, they've already done all the hard work (my preference is FastMail, but it's not everyone's cup of tea). I've been in the IT field for almost 20 years, I've done the self hosting e-mail thing. In my early teens and 20s, I didn't have anyone to please or take care of, so keeping up was easy with new e-mail standards as they rolled out, 15-20 years later, I'm divorced, work full time and have two kids, I simply don't have the time to self-host anymore. I'd rather give somebody a few $ a month to take care of that for me.
davemtl··on iPhone 6S getting iOS 14 is like the Galaxy S6 getting Android 11
Wait.. Apple support a 5 year old phone? Why the heck am I still using an Android device? I have a Galaxy S8, while I'm still lucky enough to get the occasional security update, I won't be getting the latest Android release (at least officially), although the CPU in it is probably perfectly more than capable of running Android 11.

I have been considering getting a new phone and I keep eyeing up the iPhone 11 Pro, mostly because of the longevity of available software updates. Secondly, with an Apple I'm not subject to waiting for the carrier to push out the update.

davemtl··on Ask HN: What’s your laptop?
I ended up with a Microsoft Surface Pro (2017). I like the fact I can use it as a regular tablet for web browsing and media consumption, but when I want to do some serious work, I can use it like a laptop.
davemtl··on The Future of ZFS in FreeBSD
It's my understanding that code will not be committed into OpenZFS if it cannot be compiled in both Linux and FreeBSD.

I have one running pfSense. It's never given me any trouble.

davemtl··on Redesigning the airport boarding pass (2010)
Although this blog post is a few years old, I'd like to shed a little light onto why boarding passes haven't changed in years.

To redesign the boarding pass, you have to understand how the data is processed and presented. Often the terminals and printers are shared between airlines, so there has to be a standard.

Each airline uses something called a PECTAB. This a basically a template that has coordinates of where the data is to be printed (text & logo). It's loaded on the printer each time the airline terminal application (such as Sabre, Amadeaus, etc.) connects to the CUTE (Common Use Terminal Emulator, IATA standard) API hosted on the computer which acts as a gateway to the printers, OCR scanner, etc. Did I mention this is a shared terminal by several airlines that have completely different applications? :)

A lot of the BTP (boarding pass) printers either use the older dot style printing, but the newer thermal (GPP) printers are becoming more common because they are cheaper to maintain.

Unfortunately, the terminal emulators and CUTE standard hasn't kept up to date with the available technology, a lot airlines are still running on mainframes from 25+ years ago.

davemtl··on Building a NAS
It's in the nightly releases, so it'll likely come to the stable train at next release.
davemtl··on Building a NAS
Thank you for shamelessly copying the steps in the Bhyve video I created. :-)

You'll be pleased to know that in the 9.10 nightly train, the base OS has been upgraded to FreeBSD 11 and the GUI has a UI for Bhyve, also enables VGA consoles.

davemtl··on Introducing FreeNAS Corral
No, FreeNAS is ZFS only.
davemtl··on Ask HN: Do you have examples of Facebook using your microphone for ads?
Not verbal communications, but I have seen ads relating to SMS messages I've sent or received. Perfect example was my wife advising the vacuum cleaner was broken, next thing I see when I logged onto Facebook was an advert for vacuum cleaners.
davemtl··on FreeNAS: Open Source Storage Operating System

  know that FreeNAS is technically the fork
FreeNAS as it is today is not a fork, it's a re-write.
davemtl··on Enable Two-Factor Auth on your VPN.
Real quick and dirty. But you should be able to get it to work from these notes. Be warned, I don't go into how to set-up OpenVPN. You can find documentation for OpenVPN at http://openvpn.net/index.php/open-source/documentation/howto...

You'll need to install Google Authenticator on your phone to complete the set-up.

Here are my notes: https://invaliddomain.com/openvpn-google-auth-howto.txt (please excuse the lack of a real SSL cert).

Once enabled, your password becomes <password><OTP> .. e.g. Pa55w0rd!987654

Hope that helps.

davemtl··on Enable Two-Factor Auth on your VPN.
I've been doing this for a while using the Google Authenticator PAM plugin[1]. I use the same module to add two factor authentication to both SSH and OpenVPN connections.
