germany – Should I follow COVID restrictions for the destination country only or also the layover country?


United States -> Germany (layover) -> Spain


Spain -> Germany (layover) -> United States

I’m a US citizen traveling from USA to Spain this October. The flight has a layover in Germany. Do I only need to follow the travel restrictions for my final destination (Spain) or do I also need to follow the restrictions for my layover (Germany)?

Luckily, both Spain and Germany have the same requirements of proof of vaccination or negative COVID test. However, they differ in the website/app you need to use to upload the documents. Do I need to follow all steps for Germany or can I just do Spain?

Additionally, for Spain, am I supposed to be following the Spanish-USA embassy’s rules or the Spanish-German embassy rules?


Effective September 6, 2021, U.S. citizens can travel from the United States to Spain on non-essential travel, such as tourism) if they show proof of vaccination. Please read the detailed information on the Spain Ministry of Health’s website. Additionally, travelers from the United States to Spain must present a QR code generated through the Spain Travel Health portal, obtained through the website or by downloading the SpTH app in Google Play or App Store for each traveler. Additionally, travelers must show either proof of vaccination, a negative COVID test, or a certificate of recovery.


Effective August 1, 2021, all travelers ages 12 and older must submit proof of vaccination (with a vaccine listed on this website ), proof of recovery from COVID-19 in the last 6 month, or a negative COVID-19 test in order to enter by air, land, or sea.

Please fill out the digital registration on entry at and carry the confirmation with you when entering the Germany. The confirmation will be checked by the carrier and may also be checked by the Federal Police within the framework of its responsibilities as a border control agency.

diff – How can I compare the source & destination paths with a different directory structure across different operating systems?

The source & destination paths have >100k different directories. I would like to compare the files between the source & destination without accounting for the differences between the directories.

Put another way, I want to match if the files in the source path are in the destination path. If there are differences, these would be outputted to a text file for example.

I need to be able to use a cross platform solution e.g. Windows & Linux.

How can I achieve this?

iptables – “if source == unless destination == IP”?

I am trying to set up a pihole as a domain name resolver on my router running OpenWrt.

Currently I am running this iptables-script to force every device in my network to use my (pihole-)dns server (as far as possible at least):

iptables -t nat -A POSTROUTING -j MASQUERADE
iptables -t nat -A PREROUTING -i br0 ! -s -p tcp --dport 53 -j DNAT --to
iptables -t nat -A PREROUTING -i br0 ! -s -p udp --dport 53 -j DNAT --to
iptables -t nat -A PREROUTING -i br0 ! -s -p tcp --dport 853 -j DNAT --to
iptables -t nat -A PREROUTING -i br0 ! -s -p udp --dport 853 -j DNAT --to
iptables -t nat -A PREROUTING -i br0 ! -s -p tcp --dport 5353 -j DNAT --to
iptables -t nat -A PREROUTING -i br0 ! -s -p udp --dport 5353 -j DNAT --to

I recently had on outtage on machine that made me rethink my setup since when the machine went down my whole network couldn’t resolve dns requests. I’d like to run a similar set of iptables-rules that forward all dns requests to my pihole but only if the destination isn’t, which is an OpenNic dns server.

The idea is to hand out as a second dns server and to not reroute port 53/853/5353 requests to my pihole if that server is the destination. Basically a “if destination port is 53 and source is not pihole forward request to pihole, but only if the destination isn’t

Is that possible with iptables?

Loop back address for source and destination address

A host with IP address wants to use loopback testing,WHAT are the source and destination addresses?

  • &
  • &
  • &
  • &

We know that Loop Back testing means Source and Destination should be same. According to me option 1 and 3 both are right. Don’t know what is right.

dnd 5e – Is a found Steed allowed an independent destination and creature when targeted by Dimension Door?

This question asks whether a creature summoned by Find Steed or Find Greater Steed can be brought with the caster when the caster uses Dimension Door.

I agree with the accepted answer, which says that:

(1) Assuming a Medium caster, a size Large Steed could not be brought along as a willing creature due to the wording of the Dimension Door spell, but

(2) If the caster is mounted on the steed, the Find Steed ability to “make any spell you cast that targets only you also target your steed” means that even a larger-than-caster sized steed could be affected when the caster targeted only themselves.

Assuming that this is the correct interpretation, and that the steed is not the willing creature brought along but rather an independent target of the spell, do all of the features of the spell also affect it independently?

For example, can it choose its own destination for the dimension door as a separate location from the one chosen by the caster?

And can it bring its own willing creature along with it?

kotlin – Activity como start destination en navigation component Android

Me preguntaba si existe alguna manera de utilizar el navigation component de android jetpack con una activity como start destination, ya que la pantalla principal de mi app utiliza la cámara y me es más fácil mantenerla como activity que convertirla en el nav host fragment.

<navigation xmlns:android=""

    app:launchSingleTop="true" />

    tools:layout="@layout/fragment_choose_lift_dialog" />
    android:label="LivePreviewActivity" />

Activity layout con fragment container:

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android=""


    app:navGraph="@navigation/nav_graph" />

sharepoint online – Move file to a dynamic destination folder either from source or filename

1 this flow saves uploaded documents from Cognito forms to SharePoint.
The folder structure in SharePoint looks like this

Document Approval

  • Pre Approved->Orlando Hospital->Patient Intake Forms
  • Approved

2 this flow sends an email for someone to approve the document,
then if approved moves the them from Pre Approved to Approved.

1st flow:

enter image description here

2nd flow:

enter image description here
enter image description here
enter image description here

What do I modify in the 2nd flow to create the same folder structure as Pre Approved to Approved when moving the approved documents over. Right now all documents just get moved to the Approved folder.

windows – Powershell Script to Copy Data Only into Folders That Are Empty on Destination

I have a case where a FileServer migration was not successful because the user who did not have permission on all folders.

So I have two servers with the same folder structure, but as users have already worked on the folders I can’t copy EVERYTHING again, as it could take files that the user has already deleted, for example.

However, I noticed a pattern, folders not copied due to permission error were left empty in the destination.

So, I found it by searching the following powershell script, which lists all empty folders at destination:

(gci E:DepartmentsMarketing -r | ? {$_.PSIsContainer -eq $True}) | ?{$_.GetFileSystemInfos().Count -eq 0} | select FullName

What I have been doing is accessing folders, for example in E:DepartmentsMarketing and copying from oldservere$departmentsMarketing

But there are a LOT of folders to do manually.

Does anyone know a script to nest this with a foreach to get each folder and copy the data from the UNC path and copy it to the new one?

How can I get transction destination address from raw transaction data?

I am writing a program that reads Bitcoin transactions from .blk files and performs some analysis on them. I would like to get transaction destination address (like in some transaction explorers: link.

Raw transaction data looks like this and I don’t see any address fields anywhere.

How is it possible to calculate it? Is there a (preferably C/C++) program that already does that?
Or are there any details on how to implement this?

Best regards and thanks for all answers in advance! 🙂
