kandi X-RAY | specs Summary
The block layer encompasses all content addressed block formats and specifies how blocks are addressed, how they self-describe their codec for encoding/decoding, and how blocks link between each other. IPLD blocks alone do not define data structures or types, although many codecs may convert these formats into native types, there are no type requirements or assurances about types at the block layer. | | | |-----|------| | [Concept: Block] block-layer/block.md) | [block-layer/block.md] block-layer/block.md) | | [Concept: Content Addressability] concepts/content-addressability.md) | [concepts/content-addressability.md] concepts/content-addressability.md) | | [Concept: Multihash] block-layer/multihash.md) | [block-layer/multihash.md] block-layer/multihash.md) | | [Specification: Content Addressable aRchives (CAR / .car)] block-layer/content-addressable-archives.md) | [block-layer/content-addressable-archives.md] block-layer/content-addressable-archives.md) | | [Specification: Graphsync] block-layer/graphsync/graphsync.md) | [block-layer/graphsync/graphsync.md] block-layer/graphsync/graphsync.md) |.

QUESTION
Shaking the android device and hit Debug, and it crashes every time right away. From the Android Studio logcat, it shows No source URL loaded, have you initialised the instance?:
...ANSWER
Answered 2021-Dec-21 at 02:56After some more search arounds, found this is a known issue in react-native-reanimated. As their website points out
Please note that Reanimated 2 doesn't support remote debugging, only Flipper can be used for debugging.
Another github issue also pointed out this issue
This is expected, you can't use remote debugging with turbomodules (which Reanimated v2 is using). Check out Flipper to debug your app.
https://docs.swmansion.com/react-native-reanimated/docs/#known-problems-and-limitations
https://github.com/software-mansion/react-native-reanimated/issues/1990
Removing this library fixed the issue.
- Remove the react-native-reanimated dependency in package.json
- Remove related code in android's MainApplication.java
- yarn install or npm install
- Go to the ios folder and run
pod install - Go the the android folder and run
./gradlew clean - Rebuild the app.
yarn androidandyarn ios
Another alternative is to use Flipper for debugging instead.
QUESTION
I used Cocoapods a lot, but recently whenever I was updating the pods (pod update), it started duplicating files and often didn't let me create a build for the App Store.
I updated Cocoapods to the last version possible but still didn't solve that. Then I tried to remove and re-install it.
Now is occurring another issue. When I try to run pod install on any project, pods are not getting installed like previously, but is showing this error:
ANSWER
Answered 2021-Oct-03 at 17:56The error message says there's a permission issue:
Permission bits for '/Users/myUser/.netrc' should be 0600, but are 644

QUESTION
Consider the following article in JLS §18.1.3 - Bounds
Here when we try to identify the set of bounds on the inference variables - we have one of the following situations:
...
- throws α: The inference variable α appears in a throws clause.
...
A bound of the form throws α is purely informational: it directs resolution to optimize the instantiation of α so that, if possible, it is not a checked exception type.
I think this statement is incorrect:
- this is because ideally the throws clause is mentioned to take care of checked exceptions which can happen during the course of execution of the code.
- Then why still the JLS preventing α to be a Checked Exception?
- Ideally the inference variable α must be bounded to be an exception of Checked type rather than being an Unchecked variant.
Is my understanding correct here or am I missing something?
...ANSWER
Answered 2022-Feb-18 at 11:02I think your interpretation/understanding of this statement is slightly misguided:
A bound of the form throws α is purely informational: it directs resolution to optimize the instantiation of α so that, if possible, it is not a checked exception type.
That line is referring to the resolution, which, as I understand it, is not about where throws α is, but about where α is inferred, conceivably the invocation of the method.
Consider this class:
QUESTION
Say you have a parameterized class with a deprecated constructor, and a User class that calls this constructor. In the example below, using the diamond operator, javac (version 11.0.11) does not produce a deprecation warning:
ANSWER
Answered 2022-Feb-01 at 12:27You encountered bug JDK-8257037, “No javac warning when calling deprecated constructor with diamond”:
No deprecation warning is emitted when compiling a class that calls a deprecated constructor when using the diamond syntax to specify the generic types. A deprecation warning is emitted when calling the same constructor using an explicit type argument or a raw type.
It has been fixed with JDK 17.
There’s also a reported backport to JDK 16, but none for earlier versions.
QUESTION
The UML 2.5.1 specification does not define the keyword subsets very well. I found the following in section 6.4.2:
The constraint {subsets endA} means that the association end to which this constraint is applied subsets the association end endA.
Consider the following diagram:
Intuitively, I would think this means the following:
- A Person can be a member of zero or more Clubs.
- A Person can be the leader of at most one Club.
- If a Person is the leader of a Club, then he/she is also a member of the same Club.
- If a Person is the leader of a Club, then he/she can still be a member of other Clubs at the same time.
I wonder if statement 4 is correct. In a discussion with Jim L. in the comments under his answer to another question, Jim wrote
You can’t restrict the cardinality of a subset and still have an element of the superset that violates the restriction.
If I understand this well, if a Person is the leader of a Club, then he/she cannot be a member of another Club.
Is there some place in the UML specs that defines subsets better than what I found?
ANSWER
Answered 2022-Jan-10 at 22:30In relation to your question,
In the context of UML that is the official definition that you cited.
With your statement. Your statement 4 is correct but as mentioned by Jim the cardinality shouldn't be restricted.
You can have 1 or more leaders of a club along with 1 or more leaders for an individual club.
In addition, subsets help define inheritance. For example, in your diagram if Person is a subset of Club, and they are a leader of the club then automatically they are a member.
It can get a bit nit-picky with logic as in the diagram, the subset does not only inherit from the parent class (Club) but also has its own properties (Person) and at the same time points back to the parent.

QUESTION
The JLS states, that for arrays, "The enhanced for statement is equivalent to a basic for statement of the form". However if I check the generated bytecode for JDK8, for both variants different bytecode is generated, and if I try to measure the performance, surprisingly, the enhanced one seems to be giving better results(on jdk8)... Can someone advise why it's that? I'd guess it's because of incorrect jmh testing, so if it's that, please suggest how to fix that. (I know that JMH states not to test using loops, but I don't think this applies here, as I'm actually trying to measure the loops here)
My JMH testing was rather simple (probably too simple), but I cannot explain the results. Testing JMH code is below, typical results are:
...ANSWER
Answered 2022-Jan-05 at 19:41TL;DR: You are observing what happens when JIT compiler cannot trust that values are not changing inside the loop. Additionally, in the tiny benchmark like this, Blackhole.consume costs dominate, obscuring the results.

QUESTION
This came as a surprise: I am able to declare a variable with the name record even though it now has become a keyword. Have a look at this:
ANSWER
Answered 2021-Nov-12 at 15:07OK, while looking up const in the JLS again, I saw that record is a contextual keyword whereas const is just a keyword. Contextual keywords are parsed according to context, and when the parser determines that it's not looking at a a record declaration, it will not complain.
QUESTION
We have a Prometheus container and various other services and metrics exporter containers running in a custom docker network.
In our local dev environment on Win 10 x64 using Docker desktop everything works fine, the Prometheus container can scrape the metrics exporter containers in the custom network as well as the exposed Docker metrics from the host (Win 10).
On our Ubuntu 18.04 Linux host, latest Prometheus 2.30.3 container scrapes the metrics exporter containers in the custom network just fine but is unable to scrape the exposed Docker metrics from the host.
These are the specs and config for the Ubuntu host:

Answered 2021-Nov-10 at 23:02figured this out:
in our case UFW on Ubuntu was blocking the requests on docker0 interface from our containers that are in a custom docker network.
You can see this by checking the UFW logs, you will see how it blocks the requests for 172.17.0.1 (--> host.docker.internal) on the specified metrics port.
Disabling UFW temporarily made it work, Prometheus could now scrape the Docker metrics on the host.
Re-enabled UFW, then...
