air travel – Flight Cancelled due to Covid

Our family’s flight to Portugal from Canada scheduled in May 2020 was cancelled by the TAP Portgual airline due to Covid. Since we are unlikely to be able to travel there within a couple of years we have been trying to obtain a refund from the airline without luck. Have tried calling, filing a complaint on their website, and attempted refund through my credit card insurance without any luck. As far as I can see on their website they only give the option for a voucher which would be useless for us. The amount was over $2000 Canadian.

As far as I understand they are obligated to provide a refund since the flight was cancelled.

Any advice?

Thank you

pathfinder 1e – How to avoid killing player characters due to a single (un)lucky roll?

Especially at low levels, Pathfinder characters can usually be killed easily by a single enemy attack, provided the dice fall in said enemy’s favor. An example:

The PC has a constituion score of 10 (modifier +0) and 8 HP

The enemy is of medium size, has a strength score of 14
(modifier +2) and is wealding a quarterstaff (obviously two-handed, as
a quarterstaff is a two-handed weapon)

On a hit, the enemy deals 1d6+3
damage. On a critical hit (×2 for the quarterstaff), they can hence
deal up to a maximum of 18 damage, which would kill the PC immediately with a single attack! There
is no way for a healer to interfere, the character will die at once.

I believe stats as described above are neither unrealistic for a PC at level 1, nor for an enemy they might encounter. However, I recently ran a one-shot that almost resulted in TPK within 30min due to two critical hits the enemies got in early on, killing two of the PCs and thus changing action economy massively in their favor.

How can I avoid that without pulling off some Deus ex Machina stunt?

To be clear about this: I always make sure in session 0 that everyone knows PC death is possible (and so far players have always agreed to it). But even knowing that, it really puts a damper on everyone’s mood if a character the player possibly spent hours on creating dies in session 1 because of a single attack by a generic enemy.

Simply fudging the enemies rolls is not really a possibility, since I’m using Roll20 for my games at the moment and all players are able to see my rolls (including modifiers) once made. There is the possibility to hide rolls from players (which I sometimes use for opposed checks), but I would prefer not to do that for all attack/damage rolls just to be sure, because that already implies I intend to fudge a roll at some point (which I probably would in said situation, but I’d prefer players not to think about that constantly).

While this question might seem related, the problem at hand is not encounter balance (as pointed out above), but dealing with the risk of a balanced enemy killing a player due to (bad) luck.

Huawei mate 20 lite bootloader-unlock doesn’t work due to FRP

I’ve got two huawei mate 20 lites in front of me, and I have the bootloader codes to unlock them.
But when I use adb fastboot to unlock them I get the message “Cannot unlock bootloader, you need to unlock FRP first” not with those exact words, but something like that.
How can I unlock the bootloader with the codes that i have without entering the phones settings to enable usb debugging? I feel like I’ve scanned the whole internet by now. Thank you!

germany – Do I need a transit visa in Copenhagen if I have a German D visa (due to COVID-19)?

I have a German D visa (long stay) for job purpose. I am planning to book a ticket to Frankfurt via Copenhagen. But not sure if I can take the domestic flight CPH->FRA by passing immigration in CPH with D visa (I know a Schengen visa would have no problem). Also, current pandemic may complicate the situation. Any advice?

Are there additional restrictions on domestic flights within China due to COVID-19 in November 2020?

I have a return flight from Beijing to Ningbo (11-16 November, 2020), i.e., domestic flights within China (where I live; Chinese green card). I’m not sure if it’s “business as usual” with these flights, or if there are additional measures I should take prior to these flights.

Question: Are there additional restrictions on domestic flights within China due to COVID-19 in November 2020?

I didn’t immediately find the answer through obvious searches like china domestic flights requirements.

networking – Can not to reach (ping,ssh) Ubuntu host from local network (WLAN). Is it due to router or linux setup?

I’m trying to do the simplest thing: connect 2 Ubuntu boxes via SSH to copy files over, over a WLAN router, using their IPs.
The ubuntus can’t see each other either by ping or ssh. Sshd is running, internet access from both machines are fine, they are just not seeing any local ips.

I can ping a Windows box on the same LAN (no ssh there).
I was looking for some firewall settings (as I’ve done in the past), but it’s Ubuntu 20.04 and not so familiar with state of the art now.
Suspected it’s some router setting issue, but then tested pinging that windows box, that ip was visible (after selecting “Make this PC visible for other pcs on the network”).

Also tried to connect 2 ubuntus with adhoc wifi using network manager, but all those options that worked in the past are gone or not working either.. couldn’t find up to date documentation either.
Any hints would be highly appreciated.

bitcoin core – can’t remember due to drinking

About 10 plus years ago, I was drinking heavily and decided to go online and buy some bitcoin. Since it wasn’t worth much at the time, I just kind of forgot. But now I’m bummed that I can’t recall what wallet I would have used. Does anyone have any suggestions on how I might track this down. Can I possibly download some old bitcoin wallet that I can see if it recognized my email?

air travel – What happens with your ticket if you are denied boarding due to a temperature check? (EU)

I am supposed to fly tomorrow on a domestic flight within the EU (Bulgaria). I have slight fever at the moment but feel otherwise OK.

However, I realised that tomorrow I am likely to be stopped at the temperature check at the airport.

What would happen to my ticket in that case? Am I allowed to rebook? Is there any EU regulation on this?

amazon ec2 – Postfix “randomly” rejects sending or receiving due to unable to resolve mail domain then minutes later it pass it

Few weeks ago i migrated to new mail server postfix 3.3.0, dovecot. I noticed a weird behavior, that the mail server “very randomly” rejects emails due to either of below messages:

Nov  5 00:00:35 stagesmail postfix/smtpd(26226): NOQUEUE: reject: RCPT from unknown( 450 4.7.1 <>: Helo command rejected: Host not found; from=<> to=<> proto=ESMTP helo=<>


Nov  4 21:00:18 stagesmail postfix/smtp(20973): DEFAB80E7C: to=<>, orig_to=<>, relay=none, delay=11, delays=0.02/4.2/6.4/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for type=MX: Host not found, try again)

And few minutes later, it just retry and sends the email successfully. And sometimes it doesn’t fail at all!!

I own domain1 and domain2, and they are totally resolvable as A, MX and PTR records (using dig).

Also checked resolv.conf, it has full permission

# sudo -u postfix -H cat /etc/resolv.conf


My netplan names servers:

Any help please?
