kandi X-RAY | mr1 Summary

mr1 is a Scala library typically used in Simulation applications. mr1 has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

A hobby RISC-V CPU core to learn riscv-formal and SpinalHDL. See my write-up here: [A Bug Free RISC-V Core without Simulation] While this core works and has passed the riscv-formal test suite, it’s not nearly as good as the [VexRiscv] core, which is smaller, synthesizes with higher clocks, and has better IPC even in slow configurations.

Weird behaviour in MapReduce, values get overwritten

Asked 2021-May-20 at 12:08

I've been trying to implement the TfIdf algorithm using MapReduce in Hadoop. My TFIDF takes place in 4 steps (I call them MR1, MR2, MR3, MR4). Here are my input/outputs:

MR1: (offset, line) ==(Map)==> (word|file, 1) ==(Reduce)==> (word|file, n)

MR2: (word|file, n) ==(Map)==> (file, word|n) ==(Reduce)==> (word|file, n|N)

MR3: (word|file, n|N) ==(Map)==> (word, file|n|N|1) ==(Reduce)==> (word|file, n|N|M)

MR4: (word|file, n|N|M) ==(Map)==> (word|file, n/N log D/M)

Where n = number of (word, file) distinct pairs, N = number of words in each file, M = number of documents where each word appear, D = number of documents.

As of the MR1 phase, I'm getting the correct output, for example: hello|hdfs://..... 2

I'm pretty sure my code is correct, every time I try to add a string to my "value" in the reduce phase to see what's going on, the same string gets "teleported" in the key part.

Example: gg|word|hdfs://.... gg|192

Here is my MR1 code:

Can I substract in SQL a GROUP BY SUM from another GROUP BY SUM and return a GROUP BY result?

Asked 2021-Mar-16 at 20:34

I have a SQL table similar to this:

date totalVal CTC CTC2 2020-01-01 100 Mr1 Sup1 2020-03-01 200 Mr1 Sup1 2020-01-01 300 Mr2 Sup1 2019-01-01 50 Mr1 Sup1 2019-03-01 150 Mr1 Sup1 2019-01-01 125 Mr2 Sup1 2019-01-01 100 Mr2 Sup2

I'm looking for a single query that would return me the of sum of totalVal (year 2020) minus sum of totalVal (year 2019) , per CTC and per month.

I've managed so far to get the sum GROUP BY CTC, MONTH (date) and this works fine, but can't manage to go further on.

Create data frame from EFA output in R

Asked 2020-Sep-15 at 17:02

I am working on EFA and would like to customize my tables. There is a function, psych.print to suppress factor loadings of a certain value to make the table easier to read. When I run this function, it produces this data and the summary stats in the console (in an .RMD document, it produces console text and a separate data frame of the factor loadings with loadings suppressed). However, if I attempt to save this as an object, it does not keep this data.

Here is an example:

ANSWER

Answered 2020-Sep-12 at 03:49

Looking at the str of the object it doesn't look that what you want is built-in. An ugly way would be to use capture.output and try to convert the character vector to dataframe using string manipulation. Else since the data is being displayed it means that the data is present somewhere in the object itself. I could find out vectors of same length which can be combined to form the dataframe.

debugging the practice on software development where you can find out what's happening to you code. If you're using vs code here is how you debug.

Vs code is a nice code editor with plenty of plugins that turns it into an IDE

Date validator in Angular 8 to compare two dates

Asked 2020-Jul-18 at 12:26

What is the best way to do this in Angular 8

i have two inputs that are dates fromDateMin and fromDateMAx i need to compare these two against formControlName='fromctrlname' and formControlName='toctrlname' and display errors

Conditions:

If fromDateMin is non-null, the user can't select a date any earlier than this date. If they do, the date is changed to this date. Display message in error-message-span.

If fromDateMax is non-null, the user can't select a date any later than this date. If they do, the date is changed to this date. Display message in error-message-span.

fromDate must be earlier than, or the same as, toDate. toDate must be later than, or the same as, fromDate. Display message in error-message-span.

Here is what i have tried so far

The validation part can be easily achieved using reactive forms and custom validators, as mentioned by Robert.

You can create 2 validators based on your requirements, one that validates min and max date on each form control within the group. Another validator for the group to validate that fromDate is earlier than toDate.

This is how the validator for the input controls basically could look like.

First, we create a cumulative value for each ID. This will be the column number to be expanded horizontally. Next, transform it with pd.pivot_table(). We create a new column name and update the existing column name.
