Field syntax "Google Sheets / Pivot Table Editor / Filter / Filter By Condition / Custom Formula Is"

When I create a pivot table in Google Sheets, there is one Pivot Table Editor I can use to configure the pivot table.

The bottom of the editor's interface is filter (which allows me to add filters). If I add a filter, I have to select a column from the source data. After I have selected a column, I am able Filter by condition and Filter by values,

By values is simple enough – it presents a checklist. Under the condition works well with options like Contains text and Text ends with, But the last option in the by values List is Custom formula is, This option interests me, but is not fully documented on the Help page (

What is the syntax of the formula? How do I reference the line in the source area of ​​the pivot table to which the filter is applied? I did a test that I attend = M3 = 5 and if I set the value 5 to cell M3 of the worksheet where the pivot table is located (not the worksheet that contains the source area), then the filter is all-passed, otherwise it is not passable. What is the meaning of it? How do I relate to the value of the cell in question? That would be very useful! Then I could use a formula like = AND(!="Financial", !="Income") and other such constructs, but at the moment it is (the Custom formula is Option) is almost useless.

Convert the lambda calculus functionality to predicate syntax

I try to validate the simplest concept of a formal system as a relationship between finite strings. I know that Lambda Calculus has the expressive power of a Turing machine:

<λexp> :: = < var > | λ. <λexp> | ( <λexp> <λexp> )

I thought that it could be possible to turn the functionality of the lambda calculus into a syntax closer to predicate logic by defining named functions that use finite string arguments and return finite string values.

Does anyone have any ideas here?

To change the syntax older than in the Gmail filter

I'm trying to create a filter in Gmail to delete old emails.

In the part hasTheWord, I have written label:foo_mail/fuur older_than:20d
The filter works, but when I tried to record it, the following error message appeared:

Confirm creating filter
Filter searches containing "label:", "in:", "is:", date range (e.g. "before:" or "after:") or stars criteria (e.g. "has:yellow-star") are not recommended as they will never match incoming mail. Do you still wish to continue to the next step?

and the filter does not work anymore.

Frontend – syntax coloring for function heads

I've been struggling a lot in the last few days to create a new style sheet with syntax colors, but I think the default options are pretty poor. While you can use the Settings menu to set comment colors, string colors, undefined symbol colors, and local variable colors, there is no way to distinguish between variables and functions, for example. This is what I ultimately plan to do in a color search. In essence, I want to be able to specify syntactic coloring for a defined term (whether or not it does) Plot or a variable) based on the head of that term.

Let's take a concrete example, I define a = {1,2,3} and b = 2, Is there a way to have the variable a The variable must be colored red wherever it appears (since it is a list header) b is colored blue (since it is an integer head), wherever it appears, and the function Plot Be colored green (since it is a symbolic head) wherever it appears.

To edit:
After more digging, I've found this answer:, which comes pretty close to what I'm looking for – I think the natural consequence is if it's possible is to programmatically control the context of an object through its head (and this probably shows my lack of deep Mathematica knowledge – this may not even be a sensory question).

Highlighting the R syntax in Jupyter Lab does not work

I use a Macbook Pro with High Sierra.

First, I created a virtual R environment with:

conda create -n R r-essentials r-base

Then I installed Java JDK in the new environment with:

conda install -c cyclus java-jdk

I do not know why, but it kept asking me to install JDK when I activated the R environment.

Then I installed Jupyter Notebook and Jupyter Lab with:

conda install jupyter notebook
conda install jupyterlab

But when I start jupyter lab with R, no syntax is displayed that highlights all the text in spaces. However, it works for Jupyter notebook.

What could be the cause of this problem?

Any help would be appreciated.

Many thanks!!

amazon presto – AWS Athena: Syntax for grouping data for the week ending on a Saturday

I have some problems with the Presto syntax when grouping data after weeks ending on Saturdays. I have this field named "Timestamp" and use the following to group by weeks. However, I've found that date_truncs weeks ending on a Monday and using a date_add do not need to properly group all the rows.

Select date_add (& # 39; day & # 39 ;, 5, date_trunc (& # 39; week & # 39; date (substr (timestamp, 1, 10))) as the week_ending

Do you have any suggestions on how to group weeks ending on Saturdays? Thanks a lot!

Linux error: -bash syntax error near the unexpected token & # 39; KERN_INFO "

I just started my CSC 2260 class last week. We use Virtual Box to work with Linux, and for this task we learn about kernels. I could add, load and unload. However, I have a problem when it comes to finding the golden ratio with the code given by the professor. She asks us to get the value with printk (KERN_INFO "% lu n", GOLDEN_RATIO_PRIME). But when I do that, I get a bash syntax error about unexpected tokens. I am new to this type of coding and have wondered if anyone knows what I did wrong.
