Hi. What does it mean that "Dig can query DNS name servers to find information like "Mail Exchanges""? I don't understand the last part(mail exchanges). Does that mean we can find out what mail servers are used by a network, and we can find the addresses of these mail servers?
@Moytaba It means that you can find the MX record for a domain. This tells us what servers would handle mail sent to that domain. For example dig @dnsserver somedomain MX or just dig somedomain MX.
@RuiFRibeiro Honestly I've studied a Network+ course just recently(not very deeply) and realized what are servers, ips, switches, routers, telnet, ssh etc ... I love it. but no matter how much I learn there is still a huuuge amount of things to learn! :))
I just had the odd, and fortunately unusual experience of having Debian stable breaking under me.
I'm not sure what happened, but it had something to do with the nvidia drivers.
I rebooted today, because someone came to look at my UPS, which is probably at the end of my life, and needs to be replaced. Anyway, X wouldn't come up.
After screwing around a bit, it occurred to me to just run an upgrade, which pulled in a bunch of Nvidia packages, which fixed the problem.
The odd thing about this is that I'm generally pretty good about keeping my system up to date.
Had my filling done yesterday. Wasn't as terrible as I imagined. Still no fun. It's been a while. An uncomfortable reminder that my teeth are mortal too.
@ilkkachu Yes, very true. That's true of a lot of really nasty things. E.g. cancer. Once you notice something is wrong, it's too late.
@Jesse_b Nothing.
I asked him if he was going to inject my gums. He said something like - let's see how it goes.
As it turns out, it wasn't really painful. But holding my mouth open that long was really no fun at all.
It was probably 10 minutes. It felt like hours. Towards the end I started coughing uncontrollably, but fortunately by then he had more or less finished.
@StephenKitt It looks like the 18th Feb upgrade was probably responsible. But the logs don't tell me if apt wanted to do a dist-upgrade or not. The terminal output doesn't show the commands issued. I'm not sure why not.
@Jesse_b No, no rubber blocks.
I have has occasional fillings, but not very often. Maybe an average of once a decade. Possibly a bit more often.
Actually, maybe once every 5 years. It's hard to keep count.
I'm not very careful to keep dental records. And that probably includes work that didn't actually need to be done. Dentists like to invent work if they can.
@Jesse_b Sounds unpleasant.
I used to go to a lady who kept finding stuff to do with my teeth. Eventually I stopped going to her.
Probably more unpleasant for the dentist. I remember while he was grinding down my teeth little chunks of tooth and saliva were flying out everywhere; spraying him in the face
Well, I'm going to try to take my dental hygiene more seriously. It's gone downhill in recent years, and really downhill this past year. Major personal trauma takes a toll on hygiene issues.
@FaheemMitha When you take a die grinder to something it sends particles flying everywhere. He was wearing a mask and goggles but it was still hitting all parts of his exposed face and head
the listerene company literally invented the concept of mouthwash after their product failed to sell as a household cleaning product. They took advantage of human insecurity to convince everyone they had bad breath and need mouthwash
Don't get me wrong, I use mouthwash (very rarely and only to get rid of bad breath when I don't have time to brush...which is almost never) but your mouth definitely does have good bacteria and you definitely should not use an antiseptic mouth wash
unless recommended by a doctor
In my experience flossing gets rid of bad breath better than anything else though. It's normally caused by the rotting gunk stuck between your teeth
A volt-ampere (VA) is the unit used for the apparent power in an electrical circuit, equal to the product of root-mean-square (RMS) voltage and RMS current. In direct current (DC) circuits, this product is equal to the real power (active power) in watts. Volt-amperes are useful only in the context of alternating current (AC) circuits (sinusoidal voltages and currents of the same frequency).
With a purely resistive load, the apparent power is equal to the real power. Where a reactive (capacitive or inductive) component is present in the load, the apparent power is greater than the real power as...
Well, i see that already have many questions related to my problem on this site, but i also see that NONE of the solutions work for my specific case, because of that, i am opening that question, so it is not a duplicate.
Context (environment)
Linux 19.1 Cinnamon
Expo 32

@PauloRoberto good! I hadn't read the question yet, so wanted to make sure you knew how duplicates worked. Ideally you'd link to each duplicate and show those commands, but that can be a lot of work.
@PauloRoberto Also note that we're the "Unix & Linux" guys. StackOverflow has its own life and may impose slightly different rules on stuff like this. I don't know. I'm not over there too much.
@PauloRoberto if you do an ls -ld on that directory, does it show a "." at the end of the permissions block? That could indicate selinux and possible interference, though it's not high on my list of probabilities at the moment
i found the problem guys! @Kusalananda @JeffSchaller @FaheemMitha the main reason was because expo created some files on the very initial setup of it on another directory, and on that moment i used sudo prefix to install it.
so there was a folder and some files on it that was owned by root user
that was on home/my_user/.expo dir that is completely outside my project folder.
@Kusalananda Thanks I was pretty happy with how that looks, I suppose the functions are kind of pointless because they are only being used once each now but I love functions lol. I just wish I could test it
In most of my scripts I normally function everything and the actual execution is just a single call to a main function
Anyone want to infuriate a user by giving a proper XML parsing answer? unix.stackexchange.com/questions/501954 This one has a string of questions relating to XML parsing, and he's doing it all with sed and echo and awk and he's not willing to let go.
