QUESTION
As in title, Jackson can't read utf-8.
Line 37:
...ANSWER
Answered 2021-Jan-27 at 13:54No, the error message is saying that the data is not UTF-8.
It looks to be ISO-LATIN-2 (or equivalent) based on the fact that the offending character is ł encoded as byte 0xb3.
Your choices depend on many things. If your data is coming from an outside source you may have no say in the encoding (or you may contact the data supplier and ask them to provide data in UTF8). Then you would have to do something like
QUESTION
Jsonnet's std.mergePatch implements RFC7396, but in my naive testing I didn't find a different between the way it behaved and the + operator; e.g. the + operator respects x+ syntax. std.mergePatch is implemented in Jsonnet itself, which seems to imply that it is different than the + operator, which I'm assuming is a builtin.
What is different about the semantics of these two ways of merging?
...ANSWER
Answered 2020-May-26 at 11:18Jsonnet's + and std.mergePatch are completely different operations. The + operator operates only on a single level and std.mergePatch traverses the object recursively and merges the nested objects. It's easiest to explain with an example:
QUESTION
I get json using std.net.curl.get.
Here's the code:
...ANSWER
Answered 2019-Mar-14 at 11:08Documentation says:
The template parameter T specifies the type to return. Possible values are char and ubyte to return char[] or ubyte[]. If asking for char, content will be converted from the connection character set (specified in HTTP response headers or FTP connection properties, both ISO-8859-1 by default) to UTF-8.`
So probably you should check returned http headers or you can dowload bytes and transcode them.
QUESTION
actually i'm a newbie in RN, i have a problem, I have researched everywhere but found nothing!
I got this error when i try to navigate from a screen to another "undefined is not an object (evaluating 'this.props.navigation.navigate')"
this is my component and the whole project: https://github.com/saidziani/News/blob/other-articles/components/Rowstd.js
...ANSWER
Answered 2018-May-12 at 12:17You have to pass this.props.navigation from parent to component and then, you can use it.
In your case, i think you should pass this.props.navigation from Home.js to Rowstd like this:
QUESTION
I am doing a benchmark test for my own fun! I have written a part of code in many programming languages and benchmark it using ab to see which is faster and how much. I know the method may not be so valid and can not be used as an evident to use some, but for my own information I am doing so. The other factor I want to know is how easy/difficult is writing the same sample in each language. I wrote the code in Python/Python(asyncio),Haskell,Go, Kotlin and D. I expcted the D port to be faster than Go (or at least equal in speed). But unfortunately my D code is much slower than Go. Here I put oth codes and please help me why the code is not fast as expected. Or am I wrong absolutely in my expectations?
...ANSWER
Answered 2017-Jun-17 at 21:18You're not just benchmarking Go vs D. You're also benchmarking your particular choice of non-standard Go and D libraries against each other: cbor, vibe, iris, etc. And you're benchmarking your particular implementation which can easily vary by 1000x in performance.
With this many variables, the raw benchmark numbers are pretty meaningless for comparing the performance of two languages. It's possible any one of those 3rd party libraries are causing a performance problem. Really you're comparing just those two particular programs. This is the core problem of trying to compare anything but trivial programs across languages: there's too many variables.
You can reduce the impact of some of these variables with performance profiling; in Go this would be go tool pprof. This will tell you what functions and lines are being called how many times and taking how much resources. With that you can find bottlenecks, places in the code which are consuming a lot of resources, and focus optimization efforts there.
As you do profile and optimization rounds for each version, you'll get closer to comparing real, optimized implementations. Or you'll have a better understanding of what each language and library does efficiently, and what they don't.
The problem of comparing languages is heavily influenced by the particular problem and the particular programmer. X programmers invariably find X to be the best language not because X is the best language, but because X programmers are their best when writing in X and probably chose a problem they're comfortable with. Because of this, there are a number of projects to crowd source the best implementation for each language.
The one which immediately comes to mind is The Computer Language Benchmarks Game. They do Go, but not D. Maybe you can add it?
QUESTION
I have the following classes that I want to deserialize a JSON string to using Jackson.
PushNotificationMessage.java
...ANSWER
Answered 2017-Jun-14 at 17:48Jackson is not aware of polymorphism, it just tries to create an instance of the concrete DeviceInfo class.
However, you can implement a custom deserializer that programmatically parses the device info JSON and knows when to instantiate one of the subclasses due to the uniqueness of some fields such as endpoint.
QUESTION
I am parsing JSON to present a report. While parsing the field rating it can have either 3 which parses to JSONValue.integer or 3.4 which parses to JSONValue.floating and I need to convert them as float in the report. I have profiled the code to look for optimisation and the get_number function that converts the given input to floating point is taking a lot of time and also uses exceptions for the code.
I can use fast.d (https://github.com/mleise/fast) but I am trying to see if there are anymore optimisations that can be done on get_number function that is taking up time . Is there a way to get the floating point value without using the exceptions and are there any more optimisations that can be done?
redbus.d
...ANSWER
Answered 2017-Mar-26 at 12:28I betcha just changing your get_number to this will help improve the speed a lot:
