kandi X-RAY | differ Summary

differ is a JavaScript library typically used in Telecommunications, Media, Media, Entertainment applications. differ has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Developing preservation processes for a trusted digital repository requires the utilization of new methods and technologies, which have helped to accelerate the whole process of control. The current approach at the Digital Preservation Standards Department at The National Library of the Czech Republic is to develop a quality control application for still image file formats capable of performing identification, characterization, validation and visual/mathematical comparison integrated into an operational digital preservation framework. The online application DIFFER is utilizing existing tools (JHOVE, FITS, ExifTool, KDU_expand, DJVUDUMP, Jpylyzer, etc.), which are mainly used separately across a whole spectrum of existing projects. This open source application comes with a well-structured and uniform GUI, which helps the user to understand the relationships between various file format properties, detect visual and non-visual errors and simplifies decision-making. An additional feature called compliance-check is designed to help us check the required specifications of the JPEG2000 file format.

            How to produce a point graph in R like this?
            Asked 2021-Jun-16 at 04:05

            I have basically this very odd type of data frame:

            The first column is the name of the States (say I have 3 states), the second to the last column (say I have 5 columns) contains some values recorded at different dates (not continuous). I want to create a graph that plots the values for each State on the range of the dates that starts from the earliest and end in the latest dates (continuous).

            The table looks like this:

            state 2020-01-01 2020-01-05 2020-01-06 2020-01-10 AZ NA 0.078 -0.06 NA AK 0.09 NA NA 0.10 MS 0.19 0.21 NA 0.38

            "NA" means there is not data.

            How do I produce this graph in which the x axis is from 2020-01-01 to 2020-01-10 (continuous), the y axis contains the changing values (as points) of the three States, each state occupies its separate (segmented) y-axis?

            Thank you.

            You can get the data into a long format, which makes it easier to plot. R will make it difficult to read column names that start with a number. While reading the data, ensure that you have check.names = FALSE so that column names are read as is.

            Using MassTransit with Azure Service Bus, I would suggest taking the message routing burden away from the publisher, and moving it to the consumer. By configuring the receive endpoint and using a subscription filter each instance would add its own subscription and use a message header to filter published messages.

            On the publisher, a message header would be added:

            The n2 - n1 in the case of a negative number as a result when converted to bool will yield true. So n1 turns out to be less than n2. That's why it is a bad practice to use ints in such Boolean context.

            Yes, as stated in the documentation:

            ...comparison function object which returns ​true if the first argument is less than the second

            But the implementation of the comparison here leads to failure. Try this and see for yourself:

            Answered 2021-Jun-16 at 01:14

            The difference in behaviour can be accounted for by this behaviour, described in (for instance) the following note in ECMAScript 2022 Language Specification sect 14.3.2.1:

            NOTE: If a VariableDeclaration is nested within a with statement and the BindingIdentifier in the VariableDeclaration is the same as a property name of the binding object of the with statement's object Environment Record, then step 5 will assign value to the property instead of assigning to the VariableEnvironment binding of the Identifier.

            How do I check user input against multiple lists python?

            Ex. I want to check if an input is in one of four lists. One list for up down left and right. Each list has the different acceptable ways to make the program continue. Once the input is verified to be in one of the lists i will need to figure out how to make it check against the individual lists so that the input correlates correctly to the desired direction.

            You have to initialize all instance properties somehow. And you have to do it right up front, either in the declaration line or in your init method.

            But what if you don't actually have the initial value until later, like in viewDidLoad? Then it is silly to supply a real heavyweight value only to replace it later:

            Concurrent Counter Struct with Type Argument in Rust
            Asked 2021-Jun-15 at 23:55

            I was following along with this tutorial on creating a concurrent counter struct for a usize value: ConcurrentCounter. As I understand it, this wrapper struct allows us to mutate our usize value, with more concise syntax, for example:my_counter.increment(1) vs. my_counter.lock().unwrap().increment(1).

            Now in this tutorial our value is of type usize, but what if we wanted to use a f32, i32, or u32 value instead?

            I thought that I could do this with generic type arguments:

            I haven't come across such a ConcurrentCounter library, but crates.io is huge, maybe you find something. However, if you are mostly concerned with primitives such as i32, there is a better alternative call: Atomics, definitely worth checking out.

            Nevertheless, your approach of generalizing the ConcurrentCounter is going in a good direction. In the context of operation overloading, std::ops is worth a look. Specifically, you need Add, Sub, and Mul, respectively. Also, you need a Copy bound (alternatively, a Clone would also do). So you were pretty close:
