c # – void Start does not recognize in Visual Studio when creating scripts from Unity

The "empty" start does not turn blue as it should when opening a Unity script. I am new to programming, I have done everything and still nothing.
Can you identify what the problem would be?
The code I show you has not changed at all, it only opened in Visual Studio 2019, which was updated correctly.
Follow the code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Novoo : MonoBehaviour
    // Start is called before the first frame update

    void Start()


    // Update is called once per frame
    void Update()


python – Creating N using commands of the form A = 2A-B

You are given two integers L and R. Their values ​​are initially
set to L = 0 and R = 1.

You can change your values ​​by doing the following

  • The command L change the value from L to 2L-R;
  • The command R change the value from R to 2R-L.

You are given an integer N. The goal is to find the shortest.
script after which L = N or R = N.

C # BC, successfully creating and signing the unprocessed transaction

First time on stackexchange to ask for help, sorry if I make mistakes (English is not my mother tongue).

I try to create a valid unprocessed transaction in C # with bouncycastle and I can't seem to find where my mistake is.
I do tests on the testnet network and I have used many sources to help me, mainly this one.
To start, I have the following address and private key

Address: mjhcWg5SvS96kk85R8G1wp7mru55UCNGY5
Public Key Hex: 0482052EF9560585ED62F046EE45C1B5F85448BCF1BD5CE36A7D35EB00C8A146C14BF99223907F9A8688E6F84B54FD747A637BB82F02E296203E735E7A6B40059F
Wif: 93U5P1qHPXAhXhiw1T15z3f1cBqFw9fWrd3Yzz1nDk8b2aRbrrM 
Private Key Hex: F7DBD21285F621F1C7A47AE7F63D06C276FE49839F4842DDEF805477936812A5

I want to use the btc 6.49689241 from the previous transaction (testnet)


and send (as proof) some back to the tap mwCwTceJvYV27KXBc3NJZys6CjsgsoeHmf

First, to build the unsigned transaction, I add these bytes:

01000000 (version number)
01 (number of inputs)
7dcb5c8d198fe9ac89c1ba5677e04afe0c95debcb273c1392b57c8843d2c2a91 (reversed previous tx hash)
01000000 (output index)
1976a9142de490b09ef14673af2bb4998fcb9f6b8446a84e88ac (previous tx script with its length at start) 
ffffffff (sequence)
02 (number of outputs)
496ff50200000000 (first output little endian amount. The faucet)
1976a914ac19d3fd17710e6b9a331022fe92c693fdf6659588ac (first output script with its length at start)
0046c32300000000 (second output little endian amount. My address, for change)
1976a9142de490b09ef14673af2bb4998fcb9f6b8446a84e88ac  (second script with its length at start)
00000000 (locktime)
01000000 (hash code type)

The result is


Then I recover the hash of the transaction by pressing the unprocessed transaction into a double SHA256 function that returns me


Then, I sign the transaction hash (txHash) with this function with the hexadecimal private key (prvkeyHex):

X9ECParameters curve = SecNamedCurves.GetByName("secp256k1");
ECDomainParameters dom = new ECDomainParameters(curve.Curve, curve.G, curve.N, curve.H)
ECKeyParameters params = new ECPrivateKeyParameters(new BigInteger(1, prvkeyHex), dom);
ECDsaSigner signer = new ECDsaSigner();
signer.Init(true, params);
BigInteger() sig = signer.GenerateSignature(txHash);
MemoryStream ms = new MemoryStream(72);
DerSequenceGenerator seq = new DerSequenceGenerator(ms);
seq.AddObject(new DerInteger(sig(0)));
seq.AddObject(new DerInteger(sig(1)));
byte() signature = ms.ToArray();

Which gives me an array of bytes of 72 bytes of maximum length from 30. In my last test:


Then I build my final scriptSig with the hexadecimal public key and its lengths that result as


I finally built my signed unsigned transaction:

01000000 (version number)
01 (number of inputs)
7dcb5c8d198fe9ac89c1ba5677e04afe0c95debcb273c1392b57c8843d2c2a91 (reversed previous tx hash)
01000000 (output index)
8b (scriptSig length)
483045022100abceff62d3192b686c405d10516ff0e6f9ff221c00284d766200a6abb42361be02202972970369d6b9308467e15ebafd3f6b9faf111886071e3c429b34e9407e8d2301410482052ef9560585ed62f046ee45c1b5f85448bcf1bd5ce36a7d35eb00c8a146c14bf99223907f9a8688e6f84b54fd747a637bb82f02e296203e735e7a6b40059f (scriptSig)
ffffffff (sequence)
02 (number of outputs)
496ff50200000000 (first output little endian amount. The faucet)
1976a914ac19d3fd17710e6b9a331022fe92c693fdf6659588ac (first output script with its length at start)
0046c32300000000 (second output little endian amount. My address, for change)
1976a9142de490b09ef14673af2bb4998fcb9f6b8446a84e88ac  (second script with its length at start)
00000000 (locktime)

The final result gives me that signed raw transaction


But now, when I try to send that unprocessed transaction signed on the testnet network by a web service, every time I receive an error.
sandbox.smartbit.com.au/txs/pushtx return me


live.blockcypher.com/btc-testnet/pushtx/ return me

"Error sending transaction: Error running script for input 0 referencing 912a2c3d84c8572b39c173b2bcde950cfe4ae07756bac189ace98f198d5ccb7d at 1: Script was NOT verified successfully.."

the same with tbtc.blockr.io/tx/push

I am far from mastering Bitcoin or C #, I am learning (and I want to learn how it works). Does anyone see where my mistake is?
Thank you

django how to redirect the URL after creating a publication in the same edition publication

How to block users from creating flows in a SharePoint site

Flow runs outside of SharePoint and most likely calls web services, so the only restrictions are normal SharePoint permissions on the user to read or update items. Another way of thinking … Any user with read permissions can read data from a SharePoint list using a web browser or the REST API (web services). SharePoint web services can be called from JavaScript, PowerShell, Flow, PowerApps, Power BI and almost any set of programming tools. The same applies to update and delete.

As an example, open a web browser, visit one of their SharePoint sites and edit your URL for something like this:


Disk utility: why can't I start Mac OS after creating a new partition with Bootcamp?

I recently created a new partition with Bootcamp Assistant and successfully installed Windows 10. However, I can't go back to Mac OS! I tried to press and hold the Option key during boot, but it only shows Windows as an option. I tried to click on "Restart on Mac OS" in the Bootcamp Control Panel on Windows, but it says "The OS X boot volume could not be found"

I did CMD + R, and in Disk Utility it shows me this: http://imgur.com/gallery/B569sZy

I know that my Mac OS is still there, because I see it in Disk Utility and I can see the folders / files. How can I start it or get the option to start it?

Thank you!!

Tool for creating 3D layered image [on hold]

I see more and more wireframes with this look:

UX layered

I need to explain to someone an overlapping and layered structure, so I want to use images like that.

Is there a tool that already does it or do I still have to do it myself using Photoshop?

Which Windows process is responsible for creating a pipe

The software in the Windows 10-based system I am responsible for reports intermittent failures in the creation of pipes. We believe this may be because the system got stuck on other tasks (Windows Defender scans, etc.). I would like to know what processes are responsible for creating the pipeline in order to establish the highest process priority and see if the pipeline creation failure rate falls.

javascript: creating a matrix to create a newsletter

Good evening everyone, this is my first publication, and I have a problem creating a matrix that will be used to generate a student grade chart.
From my SQL query, it will return:
Student | Note | Aval | Weight | IdAval
Mario | 5 | p1 | 25 1
John 8 | p1 | 25 1
Lucia | 7 | p1 | 25 1
Mario | 8 | p2 | 15 | two
Lucia | 2 | p2 | 15 | two
Mario | 7 | p3 | 20 | two
John 4 | p3 | 20 | two
Carlos | 3 | p3 | 20 | two

I need you to give me something like:

Student | Medium | p1 | p2 | p3
Mario | 3.8 | 5 | 8 | 7th
John 3 | 8 | 0 | 4 4
Lucia | 2.1 | 7 | 2 | 0 0
Carlos | 0.6 | 0 | 0 | 3

How to proceed?

Creating a function – Mathematica Stack Exchange

I am trying to create two functions but I have problems. The first is to convert degrees Farenheit to Kelving using this formula (F – 32) * (5/9) + 273 and another calculates the cricket's singing rate (in s ^ -1) using Dolbear's law which is Tf = 40 + N15 where Tf is the temperature in degrees Fahrenheit and N15 is the rate of squeaks per minute.

I could make the temperature work.

f (F_) = (F – 32) * (5/9) + 273

I'm just having problems with the second function.

Thank you,
