kandi X-RAY | sandy Summary
A tiny sandbox to run untrusted code. ️. Sandy uses Ptrace to hook into READ syscalls, giving you the option to accept or deny syscalls before they are executed. WARNING: While sandy is able to intercept READ syscalls there are a variety of ways to get around this. Full details can be found in the hackernews thread. Some of which can be patched to catch simple attacks, but you should use sandy with the expectation that it is better than nothing but it is not true isolation.

QUESTION
My brain froze with this advanced filtering. This task has exceeded my basic knowledge of filter, map etc.
Here I have an array with nested objects with array:
...ANSWER
Answered 2021-Jun-13 at 09:21You can use reduce method of array. First find out the object inside data array and then add that to accumulator array as new entry by preserving the original structure.
QUESTION
I have the following master table
...ANSWER
Answered 2021-Jun-02 at 07:50Access certainly does support subqueries, but you're using a crossjoin, so you will never get a null there.
Instead, left join and perform a subquery in the FROM clause.
Your query would fail identically in Oracle, by the way. There are no relevant differences between Access and Oracle here.

I am new to MongoDB. This is a MERN project. I am using the MongoDB database. I am trying to delete the comments using id which are nested in an array of objects. My document looks like this,
...ANSWER
Answered 2021-May-29 at 13:44You could perhaps change the way you structure the comments and not nest them? Since each comment already has a unique id, nesting them only makes it more difficult to access the comment object, and it's a rabbit's hole, where the nesting might never end?
I propose you add an property in the comment object A to point to other comment object B, if A is a reply or quote of B.
That way you can have an array of comment objects and modify them must easily.
Cheers.

I try to jump to a section on another page that is an entry in a th:each loop.
I have a list of student names on one page, and clicking it will bring you to a page with more information of every user:

Answered 2021-May-26 at 22:45If you want to link to a section using an #expression, that expression must be unique. If you use #studentInformation for each section, it doesn't know where to link to.
If the lists are always going to be in the same order, something like this will work for you:

QUESTION
I want to explode my table based on their 'KEY's and assort their names and emails separately into individual cols.
In Python such scenarios are dealt easily(like we use explode in pandas). since I've just started with SQL I'm finding it difficult to get my feet wet. My googling didn't help me even next to were i want, hence reaching out to the community as a my last resort for some guidance. In essence i'm trying to expand my table with my KEY as the index and the names and emails exploded across multiple cols.
my table:
KEY FIRST MIDDLE LAST EMAIL FLAG_GENDER FLAG_DESCENT 1 ROBIN A SIMPSON ROBIN@PROTON.COM M - 1 NICOLE P SIMPOSON NIC@YAHOO.COM F NA 1 SANDY LAYNE F NA 1 BRUCE NILLS BRUCENILLS@ M NA 1 ERIC WOOTEN ERICW@YAHOO.COM M NA 5 JUDY THAMES JUDYTHAMES@YAHOO.COM F NA 5 JUDY THAMES JUDY@GMAIL.COM F NA A290 RENN J JOHNSON RENNY@COMCAST.COM M C K890 JAMES RODRIGUES NA M L 189 BECKIE KATE MOORS BECKIE@GMAIL.COM F - 189 BECKIE MOORSB@YAHOO.COM F - 189 MOORS BMOORS@GMAIL.COM F - 189 BECKIE KATE MOORS BECKIE@GMAIL.COM F -output table:

I have a text string that contains several instances of numbers, example of the data is below.

ANSWER
Answered 2021-Apr-01 at 09:27- Use #1 OR #2 OR #3 below (added two additional suggestions as the author received an error with #1 and then #2 in regards to the
CASTfunction which may be a result of spacing, Data Source (PostgreSQL) specific or another issue).
CAST
It can be achieved by using the Calculated Field below (where Field represents the respective field name) which extracts all digits immediately preceding -keys; the CAST function was added to ensure that the field Type is Number (the default field Type of REGEXP_EXTRACT values are Text); also, for future reference, the Raw Input Literal R was used so that \d represents the sequence for a digit vs the default (without R) in Google Data Studio, which requires two back slashes (\\d):

QUESTION
I have an array of hashes:
[, , , ]
I'd like a function that picks out a single hash based on two entries. Ie I put in name="sandy" age=21. It would come back with a simple hash
I tried Array.select {|e| e["name"] == "sandy" and e["age"] == 21}
for some reason I get back the whole array.
In the above I was trying to isolate the offending code. I still seem to be having issues, so full code below. I've done a lot of back and forth with debugging. Some of this code might still be offensive...
...ANSWER
Answered 2021-Apr-22 at 03:40select returns an array with all the elements that fulfill the condition. Try find which will return the first single item that matches your conditions.
Also make sure your hash has the keys as strings and not symbols, otherwise you won't match any of your conditions. There is a difference between e[:name] and e["name"].
