How do I disable the password request for FileVault-protected secondary MacOS?

I have a dual boot setup with two macOS Catalina systems, each protected with FileVault.

No system is allowed to save the credentials to unlock the others, to protect them against each other and to keep things separate.

However, MacOS always asks for a password to unlock the other system's hard drives after booting.

Is there any way to disable this prompt without storing the passwords in the keychain?

I tried adding an entry to / etc / fstab with the volume UUID and options rw,noauto but that didn't help.

How do I request witness information from a Bitcoin full node?

So I'm trying to create a Bitcoin Block Explorer using my own Python library. I'm just doing it as an exercise to better understand how Bitcoin works under the hood.

When I send a block message to request information about a particular block, I don't get any witness information for the transactions.

I read that I should enable this service when I send my version message to receive witness information. I believe I do, but still receive no testimony.

The My Services field in my version message looks like this:

Services bit field: [1, 0, 1, 1, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

However, the version I receive contains the following service fields:

What can I do to get witness information?

Reference Request – The Structure of PSL (Z_p)

As you know, the group $ mathrm {PSL} (2, mathbf {Z}) $ is isomorphic to the free product of two cyclic groups of orders 2 and 3.

Is there a similar description of the projective special linear group about p-adic integers? If so, where can I find it? If not, what is known about the algebraic structure of? $ mathrm {PSL} (2, mathbf {Z} _p) $? Where can I find it?

Architecture – How to Simulate an Asynchronous Request in an Assembly (Pseudocode)

I'm wondering how you would write the code for an asynchronous request in assembly (just with pseudocode assembly to convey the point). I wonder how you're tracking the current thread / fiber / flow / whatever-its-called, then delegate it to something else (I'm thinking of a JavaScript promise), then wait a while and then return to the previous thread / fiber / Flow / whatever. What's going on in terms of thread / fiber / whatever? What happens when a branch to the "current" process occurs (the promise, say, that it happens somewhere else in the assembly pseudocode) and then returns to the place in the executing thread / fiber / whatever.

I can not really imagine my example because I find it hard to imagine. It seems like the thread / fiber / whatever causes some kind of spiders jmp $but now and then check to see if a Boolean value has been set to know that the promise has returned. Meanwhile during this spinning / waiting jmp $It would execute another code and then jump back to the place where the code stopped before the promise began, when it was finished, possibly using interrupts or the like.

Basically, I wonder what the skeleton of the pseudocode would look like in assembler so I can see (a) What I have to consider in terms of pieces, and (b) from where These pieces usually go. This would help in implementing async functionality in an assembly-like background.

Code Request – Get the results of selected cells in a NB1 notebook from another NB2 notebook

My goal is to read the results of multiple labeled cells in a notebook NB1 from another notebook NB2, Following the suggestions of a member of this forum, I have written the following code that only works for a single tagged cell. If I want to read the results of more than one selected cell in one go, it will not work. and NB1 is automatically closed and generates the message: NotebookEvaluate() is not able to find NotebookObject(),

(* I saved the following code at the bottom of NB1, which includes all  the tagged cells*)
nb = CreateDocument@{
ExpressionCell(
 Defer(Print("DataImport"); CreateDialog({"A", DefaultButton()})),
  "Input", CellTags -> {"DataImport"}),
ExpressionCell(
 Defer(Print("MultiplierMatrix"); 
  CreateDialog({"B", DefaultButton()})), "Input", 
 CellTags -> {"MultiplierMatrix"}),
ExpressionCell(
 Defer(Print("SectorIOMarketChains"); 
  CreateDialog({"C", DefaultButton()})), "Input", 
 CellTags -> {"SectorIOMarketChains"}), 
ExpressionCell(
 Defer(Print("RefiningMultiplierMatrix"); 
  CreateDialog({"D", DefaultButton()})), "Input", 
 CellTags -> {"RefiningMultiplierMatrix"}),
ExpressionCell(
 Defer(Print("DensityPlot"); 
  CreateDialog({"E", DefaultButton()})), "Input", 
 CellTags -> {"DensityPlot"}), 
ExpressionCell(
 Defer(Print("CauseEffectDiagram"); 
  CreateDialog({"F", DefaultButton()})), "Input", 
 CellTags -> {"CauseEffectDiagram"}), 
ExpressionCell(
 Defer(Print("EdgeBetweenness"); 
  CreateDialog({"G", DefaultButton()})), "Input", 
 CellTags -> {"EdgeBetweenness"}), 
ExpressionCell(
 Defer(Print("RefiningLargestSCC"); 
  CreateDialog({"H", DefaultButton()})), "Input", 
 CellTags -> {"RefiningLargestSCC"}),
};

nb = NotebookOpen(
"C:\Users\ttemel\Desktop\World_Bank_projects\WB_Contract_2\
Extension_to_1st_contract_27oct19\IOdatabase_oecd\database_IOtables_
SA_NO_UK_2000_2015_run_1.nb");

(*I run the following code in `NB2` while keeping `NB1` open*)
NotebookDirectory()
Get("C:\Users\ttemel\Desktop\World_Bank_projects\WB_Contract_2\
Extension_to_1st_contract_27oct19\IOdatabase_oecd\database_IOtables_
SA_NO_UK_2000_2015_run_1.nb");

ClearAll(listTags);
Notebooks()
listTags = {"DataImport", "MultiplierMatrix", "SectorIOMarketChains", 
"RefiningMultiplierMatrix", "DensityPlot", "CauseEffectDiagram", 
"EdgeBetweenness", "RefiningLargestSCC"};

NotebookEvaluate(nb, EvaluationElements -> {"Tags"->
{"RefiningLargestSCC"}})

This code works for a single tagged cell, but I want to run it for the entire list of tags listTags, Besides, it works for listTagsI really want to know why NB1 is closed. Is this a bug?

Reference Request – Example of an algebraic system that introduces infinite sets but not infinite numbers, allowing inversions of infinite sets.

When expanding real numbers, infinite sets usually do not cause much trouble, but if we consider infinitesimal numbers, they are more problematic.

This is because many things that were classically alike cease to be equal when we introduce infinitesimal numbers. For example, the sums of convergent series that are classically equal are suddenly differentiated by an infinitesimal number.

On the other hand, if we introduce infinite sets, everything that is the same will remain the same (except for entities that were equal only in terms of regularization).

So my question is, is there a well-known algebra on real numbers that introduces infinite sets and allows their (nonzero) inverses, but somehow avoids the introduction of infinitesimal numbers?

For example, can an inverse of infinite size be infinite or something else?

Javascript – Why are arrays within an object in the API request with Axios undefined?

I have created an API that sends this information:

{ 
  title: 'algum título', 
  content: ('vários parágrafos')
}

The method that receives the data is as follows:

async componentDidMount() {
    let response = await axios.get("http://localhost:8000");
    let api = response.data;

    this.setState({ data: api });
  }

Both title and content are received correctly. I can see the data by logging, but the variable type is wrong.

console.log(typeof api.title) // string
console.log(typeof api.content) // undefined

To solve the case, I use the brackets. Only then can I use the map.

{this.state.data.title}

{(this.state.data.content).map(elem =>

{elem}

) }

The point is not that I can not solve the problem, but I would like to understand it. Understand why that happens.

node.js – Google Drive API without automatic synthesizer request

I have an app that only works with my account, which means I do not have to authorize anyone to access their drives, but I do not think there's any way to work with the API without using the oauth system do I have to ask the user to log in?

I used the playground to once authenticate myself and then reuse the token by updating it on my backend. Is not there an easy way to do this by skipping the playground part?

mysql – Merge multiple selects in one request

I need to extract data with selects statements based on the same conditions, with a little change. I want to summarize all my selects in one statement:

select   Date_,  application_name,count(*)   total1  
from   PDETAIL
where Application_Name='My_Apllication' and  
SUBSTR(Statistics_Variables,36,1)='1'  and
File_Arriving_Date between date-29 and date-1
group by 1,2   

and

select   Date_,  application_name,count(*)   total2  
from   PDETAIL
where Application_Name='My_Apllication' and  
SUBSTR(Statistics_Variables,38,1)='1'  and
File_Arriving_Date between date-29 and date-1
group by 1,2
