kandi X-RAY | faber Summary
This project started as a clone of Boost.Build, to experiment with a new Python frontend. Meanwhile it has evolved into a new build system, which retains most of the features found in Boost.Build, but with (hopefully !) much simplified logic, in addition of course to using Python as scripting language, rather than Jam.

QUESTION
i am kind of newbie at asp.net core and i get a course from udemy. I did everything like instructors did. When i try to add test datas to database i get error that System.InvalidOperationException: 'The instance of entity type 'ProductCategory' cannot be tracked because another instance with the same key value for {'CategoryId', 'ProductId'} is already being tracked. When attaching existing entities, ensure that only one entity instance with a given key value is attached. Consider using 'DbContextOptionsBuilder.EnableSensitiveDataLogging' to see the conflicting key values.' .
I research a lot about that but i understood nothing because it seemed very complicated to me.

I am stuck in finding a common key stored in 2 different substings of 2 different dataframes and then output a 3rd column:
...ANSWER
Answered 2020-Nov-18 at 14:58Assuming that your codes are always split by a whitespace.
You can use list comprehensions to check the presence of each code in the Code1 column in the Code2 column. By retrieving the indices of matching codes, we can get a Dataframe containing rows with overlapping codes.
Then we can update the original dataframe to get the intended output.

I'm trying to learn about animating plots with gganimate, and I'm wondering if someone has a tip for the problems I'm running into. In an effort to make things simple, I'm doing this by creating a new project in RStudio Cloud, installing the ggplot2, gganimate, and datasauRus packages, and following this example from Isaac Faber:

QUESTION
I have a PHP xpath query that works well for searching on a single node of my XML file. In simplified form, it looks like this:
...ANSWER
Answered 2019-Jul-29 at 14:25The problem is more with how you select the nodes, name() will give you the name including the prefix, so you don't need to specify this as a separate part of the query (I think as it's the default prefix it is blank). So the value will be AUTHOR1 etc. So change the way that you select the author nodes to just use /*[starts-with(name(), 'AUTHOR')]...
QUESTION
I want to ask a basic question. I am following story of Alice from Indy offical docs. When Faber College issue identity to Alice then faber college and Alice both know the identity of Alice. It means Faber College maintaning local database of students and assign identity to its students. Which students kept in their wallet. Then how identity is decentralize? Faber college local database might be a honey pot for attackers.
...ANSWER
Answered 2019-Jun-28 at 04:11In this case Faber College is the identity issuer and Alice is the holder, as an Identity Issuer I would have to know what and who the credentials i am assigning to. i.e. College-Transcript
Identity is decentralized when there is another issuing party, for example Job-Certificate from Government Agent ( by following your example ). From there on the Holder (Alice) would consist of 2 credentials which is 1.Job-Certificate , 2.College-Transcript. Thereon only Alice would have the authority to share a credential supply proof with another party. The link upon Issuer-Holder must exists in order for the Verifier to verify the proof that is supplied later on.
Secondly, the wallet creation may be done by another agent (as all wallet creations are done offchain) faber college would not know the existence of Alice. A connection must be established in anycase for faber college to know the existence of Alice, if so the database would not be on faber college agent.

QUESTION
I was going through the getting started documentation of Hyperledger Indy SDK.
Step 4 goes through the process of onboarding new members through a steward. I have particularly three broad queries for the procedure outlined in the documentation.
What does the call to the ledger for the creation of NYM transaction mean? Is it not, that pairwise DID's were supposed to be stored in the wallet and not made public.
Which key of the Steward does Faber query the ledger for, is it Stewards legal DID or the one that it created for Faber.
For the case of private DID's stored in the wallet. How does an entity like Faber obtain the encryption key of the entity sending the invitation for a connection?
ANSWER
Answered 2019-Apr-10 at 07:37Your confusion is righteous and what pointed you out also have confused me now. I've turned to Indy community and got to know that this part of the walkthrough tutorial is a bit outdated. Quoting Stephen Curran from Hyperledger Indy's RocketChat channel:
The pairwise DID concept had not been fleshed out enough and so all DIDs in code were being written to the ledger.
To elaborate on public and pairwise DIDs bit more:
NYM Transaction write a DID with associated Verkey (a public part of keypair). You have to however distinguish between public DID and pairwise DID.
Public DID - is identifier which you publish out there for everyone to know. If you are an institution, you want to have such identifier. People/their devices can then use it to establish the initial secure connection with the institution.
Pairwise DID - is DID which identifies secure channel you've establish with someone. For example, if once you've contacted an institution using their public DID, they would generate pairwise DID (a key pair and DID identifier) for talking with you. You would also generate pairwise DID to identify connection to them (and to encrypt the communication using the keys associated with the pairwise DID)
- I think you are referring to the step 10:
Faber asks the ledger for the Verification key of the Steward's DID by calling did.key_for_did.
So here Faber reads Steward's DID and its associated verkey (a public key) from the ledger. Faber then uses this key to encrypt the message - the message won't be decryptable by anyone but the Steward, holder of the private part for that verkey.
Question 3Here's how connections are typically established:
Some secure channel is assumed to be established by which one party receive connection invite from the other. You could get for example invite via HTTPS, or simply by employee of a bank presenting you a QR code containing the invite for connection from a Bank. When generating the connection invite message, the inviting party generates pairwise DID with verkey. This is included in the invite message, so assuming you got this invite secured delivered by any means, it's safe to say you can send encrypted messages to the inviting party. At this point, you would generate your pairwise DID and Verkey for this connection and send this data to the inviter. At this point, you have established secure connection because you both securely exchanged each other's pairwise DIDs/Verkeys for the session.

Install faber
You can use faber like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
