Second, I don't believe that it violates the Windows 10 TOS. And, again, this is very commonly discussed among experts.

LOL, he seems to have a very loose definition of expert.

The idea behind ChromeOS is to be "set and forget." It's not meant to be twiddled with.

@DustinB3403 I used RC in the past, and it should be able to handle this without issue. You should only need to pay for a single user for this to work.

We currently use RC. Honestly, as much as I want to bag on it, I can't. It works, all the time. The only thing I ever have to touch on RC is add/remove users.

If you are only doing a single line or two, RC is basically unbeatable. Get beyond that, they start getting pretty pricey.

@WLS-ITGuy Typically we use the time to rebuild. Any VM should, in theory, be quick and easy to rebuild. If it isn't, it's the perfect time to make it so.

If you absolutely have to convert rather than move through application migration, then there are disk conversation tools that change the format. There's very little needed for the migration.

Build a super dedicated, fully cooled, fully wired, LARGE space with room to move about data closet on a raised floor.

Moving from that port which was only giving 10FDx to an unused port, gave us 1000FDx.

I'm not sure where this issue stems from..

Got it sorted out, for some reason (and I'm still working on the specifics) our ESXi hosts secondary NIC keeps falling to 10FDx (likely some misconfiguration at setup).

I've moved XO off of this nic, and performance has been fixed.

If you want to improve ESXi performance, install KVM.

Registry editor:

Hkey_local_machine\system\currentcontrolset\services\nlasvc\parameters\internet
Open- enableactiveprobing

Change value data from 0 to 1

Ok and Restart the computer.

This removes a warning that does not mean what it claims to mean. It is a bad warning that end users should normally not see as it is false and confusing.

Working with Postfix and got some hidden characters that were killing my file. So hard to find. But here is how you do it. In this example it is for the vmail_mailbox file, but this applies to just anything.

tr -cd '\11\12\40-\176' < vmail_mailbox > vmail_mailbox_clean

I know @Oksana is here, maybe she can give some input.

That's just a marketing account most people block.

I've been out drinking with Oksana.

If you want to use Castopod, you almost certainly want to connect it to an S3 bucket. But the documentation on the site is missing a couple critical elements. The bucket must be specified and the format of the host needs the header. Here is an example configuration from the end of the .env file.

media.fileManager="s3"
media.s3.endpoint="https://s3.us-east-001.backblazeb2.com"
media.s3.bucket="bucketname"
media.s3.key="mykeyID"
media.s3.secret="mykeySecret"
media.s3.region="us-east-001"

This took some tracking down. The media.s3.bucket is absolutely critical, but does not appear in the documentation. The https:// I'm told is required as it prefixes bad data without it.

Turns out it is an App Armor restriction that Unity hasn't mentioned anywhere in their documentation even though we are at LEAST two releases into this problem. The fix is simple, but should be part of the install docs.

This is the error for the search engines:

No usable sandbox! Update your kernel or see Chromium Docs - Linux SUID Sandbox Development 48 for more information on developing with the SUID sandbox. If you want to live dangerously and need an immediate workaround, you can try using --no-sandbox.

To Test:

sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

And then for the real fix: /etc/sysctl.d/unity.conf

kernel.apparmor_restrict_unprivileged_userns=0

If you run Ubuntu or other Linux system using the UFW firewall mechanism, and you probably want to limit at least some ports to only receiving traffic from CloudFlare's proxy servers. CloudFlare provides scripts for iptables, but not for UFW. But they do provide their IP list in a handy format. So here is all you need to do...

cd /tmp
wget https://www.cloudflare.com/ips-v4 -O ips-v4-$$.tmp
wget https://www.cloudflare.com/ips-v6 -O ips-v6-$$.tmp

for cfip in `cat ips-v4-$$.tmp`; do echo "ufw allow from $cfip to any port 80 proto tcp"; done
for cfip in `cat ips-v6-$$.tmp`; do echo "ufw allow from $cfip to any port 80 proto tcp"; done```

Notice this doesn't take action, it produces a handy human readable set of ufw instructions that you can audit before running. Just copy the output to a file and "bash file" to take action. Make sure to set the port to 443 in most cases, or run twice, once with 80 and once with 443.

@EddieJennings yeah, that would be nice for sure.

@CCWTech they serve little purpose in the modern world. It's just the network domains that are automatically tried when you put in a URL with only the hostname and leave off the network name. Which no one does, so it's unused. It's not a LInux thing, it's a general networking thing so the same on desktops, Windows, wherever. Just a standard part of DNS, but like many DNS functions, one that is mostly a vestige.

If you use Active Directory on Windows, it fills it at least one search domain automatically. Windows is about the only place to see search domains still used frequently. This is primarily used for when Linux is put onto legacy style Windows based LAN networks.

@travisdh1 said in OpenAI ChatGPT 4.1 vs 4.5 Models:

This is a somewhat surprising because all the recent reviews I've read or heard claim o3 and o3-mini are the best models so far at least for programming purposes. Are 4.1 and 4.5 newer than o3?

Much newer, 4.1 is actually the newest, very confusing. 4.1 is the most up to date. But a much smaller model.

@Obsolesce said in OpenAI ChatGPT 4.1 vs 4.5 Models:

@travisdh1 o3 is for the best advanced reasoning.

Right o series are reasoning models. GPT are intelligence models. o for strategy, GPT for tactics.
