QUESTION
I don't really understand what the identifier is or how it is used.
Is it arbitrary? Is it my app name in reverse? Below I use "test" but should it be: "com.mydomain.myApp.test"? Or my app bundle identifier: "com.Soundpaper.soundpaper.fakeID123"? Or what?
Thank you.
...ANSWER
Answered 2021-Mar-05 at 08:58The KeychainItemWrapper is a wrapper class to hide all the CFRef conversion stuff from the "typical" developer. Being so, all the "rules" of the Keychain services in the Security framework hold.
Therefore, whenever you access a keychain item, the framework will automatically "add" the bundle id of your app to that item, to ensure that you can read only your own items, see e.g. SecItemAdd discussion.
Hence, the identifier
is completely arbitrary and may only raise conflicts within your own app, not with others.
Remark: if you specify an accessGroup
, you can share keys between apps, see Sharing Access to Keychain Items Among a Collection of Apps
QUESTION
I'm trying to make a home made function mapping chain. Thing is, I want to make sure typing stays consistent trough the mapping chain. My problem is that I don't know how to write f(x:T) => U
For a proper example of what I'm trying to do:
...ANSWER
Answered 2020-Dec-14 at 08:58You need to use a generic type parameter to refer to whatever the return type of the innerFunction
is, so that you can then provide that type to TS when you recursively refer to myChainer
.
Here is what that would look like:
QUESTION
TypeScript function chaining, but I want to programmatically chain them.
Example class: chain.ts
...ANSWER
Answered 2020-Nov-09 at 14:45Let's start from the first misunderstanding I can find:
Now, I'm still fairly new to JavaScript and TypeScript, so I figured out that the function within this class is actually an element of an array of the instance of the class.
This is not the case. Square brackets in Javascript are used for all property lookups, not just array indexing. x.foo
is actually equivalent to x["foo"]
, and the same syntax works for arrays since arrays are just objects. Classes in Javascript are just objects that have a prototype property, which is itself an object. It contains a list of default attributes, and if you instantiate a class and look up a property that isn't in the object, it'll search for it in the prototype. So, looking at the code:

QUESTION
I'm new to C++, and I'm writing a simple blockchain program as a sort of exercise. When I run the below code, I seem to get an error of sorts:
...ANSWER
Answered 2018-Jul-24 at 18:26Currently, BlockChain::chain
is an array with unknown size. But when you access chain[0]
in BlockChain
's constructor, you're assuming that chain
points to valid memory, which it doesn't because you never initialize it. That's why you're getting a crash due to a bad memory access. I would suggest the use of std::vector
instead of Block[]
, which you can resize as needed:

I have a pyROOT script where I use TChain::AddFriend to combine two TTrees:

Answered 2018-Jul-10 at 04:11I had a similar question, and found an answer (well, workaround) on the ROOT forum:
https://root-forum.cern.ch/t/accessing-a-friend-ttree-using-pyroot/25513
although no solution was presented using TFriend
.
Instead, RobS found a workaround for his own question of just loading the two TFile
and TTree
separately and running LoadTree()
and GetEvent()
on each TChain
