Python Regex extract string between possible DOT characters

I am trying to extract a string within a few conditions and its getting a bit complicated. I tried a bunch of expressions, I understand that (DOT) is a special character but no luck. Im not great with regex

The part I want to extract is in bold

N.B: Ive replaced all “.” with (DOT) so they are more visible

possible permutations

  1. (DOT)string
  2. string
  3. string(DOT)string

How do I extract the first “string” in all these conditions. It will 99% be characters not numerals

According to the cryptocurrency tracking platform Coingecko, DOT’s market cap is currently around $ 13,030 billion. The market value of XRP is approximately 13.003 billion dollars. The sharp increase in the DOT price of up to 50% in recent days has increased the market value to very high levels.
Polkadot (DOT) outperformed the bad times of XRP and became the fourth largest cryptocurrency in terms of market capitalization.
What do you think of DOT?

dot diagram of jordan form

$dim N(T − λI) = 1, dim N(T − λI)^2 = dim N(T − λI)^3 = 4$
I want to know how to find dot diagram and jordan block of T corresponding to $lambda$.
I know in dot diagram, number of dots contained in the $r_i$ th row is = $dim((N-λI)^{i})$$dim((N-λI)^{i-1})$
But in the particular problem second row has more dots than first row. In that case how the diagram and jordan block will look like.

How to disable DoH and DoT network-wide for Apple iOS and macOS

I am running an the Open Source OpenWrt router firmware and wish to disable DoH and DoT for the whole network. In my network lots of latest iOS and macOS devices.

Operating systems Apple

Apple’s iOS 14 and macOS 11 will support both DNS over HTTPS and DNS
over TLS (DoT) when they are released in the fall of 2020.

How to resolve single-name (no dot) domain names with upstream DNS server on Linux workstations

We are using dnsmasq on our firewall machine and have set up the machine with the hosts file for all our printers and other shared resource machines. This should let us use this as a distributed hosts file, as dnsmasq will respond to queries that it sees in the local machine’s hosts.

This is working well from Windows machines. A NAS device, “tusker”, for example, is set up as I can “ping tusker” from any windows machine and it will correctly resolve that to We also have some Linux workstations, however, and none of them will resolve any single-name domain name. They are a mix of mostly Debian-based distros (Debian, Ubuntu, Mint, Arch) and universally the response to “ping tusker” on any of them is “temporary failure in name resolution”. They don’t seem to be passing on any single-name domain name queries to the DNS server. It sees there are no entries in its local hosts file and stops there without sending the query up.

I’ve tried “options ndots:0” in resolv.conf to no effect. Is there a way to tell the Linux resolver to always send names up to resolve regardless of how many levels are in the host name?

Not showing amazon echo dot as output or input device in ubuntu sound setting after connecting through bluetooth

Though bluetooth pairing is successfull with Amazon Echo dot 3rd gen from Ubuntu 18.04.4 LTS( Echo says Now connected to <my machine's name>), The device is not listed in the sound setting as input/output device, So the problem is ,sound is coming from the inbuilt speaker and not from the echo device.

Things that I’ve already tried

  • connecting/disconnecting device multiple times
  • bluetooth pairing while laptop is playing some music(on youtube)

not really sure which command / logs to be checked for this issue. Please suggest.
