kandi X-RAY | nkn Summary

nkn is a Go library typically used in Blockchain applications. nkn has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

The core of the NKN network consists of many connected nodes distributed globally. Every node is only connected to and aware of a few other nodes called neighbors. Packets can be transmitted from any node to any other node in an efficient and verifiable route. Data can be sent to any clients without public or static IP address using their permanent NKN address with end-to-end encryption. The network stack of NKN network is open source at another repo called nnet that can be used to build other decentralized/distributed systems. The relay workload can be verified using our Proof of Relay (PoR) algorithm. A small and fixed portion of the packets will be randomly selected as proof. The random selection can be verified and cannot be predicted or controlled. Proof will be sent to other nodes for payment and rewards. A node in our network is both relayer and consensus participant. Consensus among massive nodes can be reached efficiently by only communicating with neighbors using our consensus algorithm based on Cellular Automata. Consensus is reached for every block to prevent fork. More details can be found in our wiki.

You need to tell the http client that you expect a plain text response rather than the default which is JSON

Note that when specifying a responseType other than JSON you do not need to need to give a generic argument like this.http.get as it is already specified.

Re-directing a string containing a git command under double quotes fails

Asked 2019-Jul-24 at 10:50

I am creating a bash script-file from an automated bash installation.

That file should only cd into a git directory, look for a new version and if there is one pull latest changes and rebuild.

The script itself works and the file gets created, but on creation it shows me fatal: not a git repository (or any of the parent directories): .git twice.

As rightly pointed in the other answer, running in debug mode should have help you identify the problem.

The problem is with the command-substitution $(..) getting expanded inside ".." when writing the following commands to the file. The shell has run the commands in the current path instead of appending the command to the file nknupdate.

curl -sL https://deb.nodesource.com/setup | sudo -E bash -

It downloads a bash script and directly executes with sudo permission. This can be very dangerous. Don't do it.

Instead curl -O https://deb.nodesource.com/setup Just check the script by less setup. If it looks fine, execute by sudo setup

Answer for your first question.

setup is a package installer script. It adds some packages to sources.list and installs some gpg keys. It's not necessary to reverse the changes made by it.

Find, Add, Replace every time - sequentially

Asked 2017-Aug-14 at 15:30

I have an input like this, i would like to append a value and it should add value to the next found ID and it should increment sequentially for every value it finds in the file

In short, find FR: (516554) & AT:(929121) and add sequential number to it and replace the value with new generated value FR: (516554001) & AT:(929121001)

my input file 'NKN+S:KSSSS+FR:516554+20020716++2'NKN+S:KSSSS+AT:929121+19991116++2' 'NKN+S:KSSSS+FR:516555+20020716++2'NKN+S:KSSSS+AT:929122+19991116++2' 'NKN+S:KSSSS+FR:516556+20020716++2'NKN+S:KSSSS+AT:929123+19991116++2'

Output file should be something like this 'NKN+S:KSSSS+FR:516554001+20020716++2'NKN+S:KSSSS+AT:929121001+19991116++2' 'NKN+S:KSSSS+FR:516555002+20020716++2'NKN+S:KSSSS+AT:929122002+19991116++2' 'NKN+S:KSSSS+FR:516556003+20020716++2'NKN+S:KSSSS+AT:929123003+19991116++2'

Many thanks in advance

How to print the current filename in a plot in matlab?

Asked 2017-Mar-23 at 22:01

I have one .m file per plot and want to see in my draft printouts, which file was used to create it.

This should be done with a function which can be placed in my .m file and commented out, for the final version.

I suggest instead of commenting out a function from the code, use a proper flag. For instance the code can be something like this:
