I’ve been asked to disable certain computers/users at 5:15.
I know how to restrict access to the file system on the hour, but
a] that doesn’t give enough grace time or too much, and
b] doesn’t restrict enough, it only cripples
I saw this question posted and can’t seem to find it for some reason, so I’m posting it again.
There’s a leetcode problem that’s asking for the number of possible strings that are alphabetically between 2 strings (A and B) of equal length such that string C is not a substring of any of the strings. How would you approach solving it?
I solved the trivial case where if C.length = A.length and C is lexographically not between A and B, the answer is just the number of possible strings between A and B. The problem is I don’t understand how to solve the normal case where we try to calculate the number of strings that contain C by “growing” C (ie. adding characters on either end).
What is the recurrence equation of this function and how to calculate it
public static void recursif( ArrayList< Borne > V, ArrayList< Pair > resultat ) {
if( 1 < V.size() ) {
ArrayList< Borne > V1 = new ArrayList< Borne >();
ArrayList< Borne > V2 = new ArrayList< Borne >();
ArrayList< Borne > Sd1 = new ArrayList< Borne >();
ArrayList< Borne > Sd2 = new ArrayList< Borne >();
ArrayList< Borne > Sf1 = new ArrayList< Borne >();
ArrayList< Borne > Sf2 = new ArrayList< Borne >();
double minima = V.get( 0 ).valeur;
double maxima = V.get( V.size() - 1 ).valeur;
int i = 0;
for( ; i < V.size() / 2; ++ i ) {
Borne b = V.get( i );
V1.add( b );
if( Borne.Cote.FIN == b.cote ) {
Sf1.add( b );
} else if( maxima <= b.parent.fin ) {
Sd1.add( b );
}
}
for( ; i < V.size(); ++ i ) {
Borne b = V.get( i );
V2.add( b );
if( Borne.Cote.DEBUT == b.cote ) {
Sd2.add( b );
} else if( b.parent.debut <= minima ) {
Sf2.add( b );
}
}
ajouterProduitCroise( Sd1, Sd2, resultat );
ajouterProduitCroise( Sd1, Sf2, resultat );
ajouterProduitCroise( Sf1, Sf2, resultat );
recursif( V1, resultat );
recursif( V2, resultat );
}
}

If there is no global clock in Distributed systems , then what is the solution for synchronization in DS ? Also , no global clock in DS is a direct consequence of the fact that the only communication is by sending messages through a network. Can someone please explain how the communication via message passing has resulted in no global clock ?
I came across this problem on Leetcode (original, section 2; also attached below).
I thought it would be as simple as counting the lexicographic difference between 2 strings (as exemplified here) and then removing 26*(length(A) - length(C) + 1).
I’ve tried with a couple different strings and this doesn’t seem to give the correct answer. Any ideas on how to solve this?
I’m writing an assignment involving some statistics comparing different implementation methods for web applications. I’ll be using some downloaded software and web pages I create, on both virtualized environments (docker, VM, cloud) and bear metal. I intend to measure response times from the client side.
Do I need to have instrument validation and what would it look like?
I am trying to learn more about the IPSec and VPN. I am using TunnelBear on Firefox. When I start VPN service, I only see TLS connections on Wireshark but not the ISAKMP or other IPSec related packets. I did another trial with the Cisco AnyConnect client and connected to my school. Still I see TLS connections but nothing about IPSec related messaging. In my test setup I am using my Windows PC and the required VPN software. The servers I am trying to connect should be VPN servers.
Do these programs use another method to connect to those servers? Why do I only see TLS connections? Thanks.

What is 4365 − 3412 when these values represent signed 12-bit
octal numbers stored in sign-magnitude format? The result should be written in
octal. Show your work.
Octal to binary:
By recognising the role of the sign bit, we can
represent positive and negative 64-bit numbers in terms of the bit value times a
power of 2. The binary number x, where xi means the ith bit, represents the number:
(x11 * -2^11) + (x10 * 2^10) + (x9 * 2^9) + … + (x1 * 2^1) + (x0 * 2^0)
I have used the formula given above to convert the value of octal 4365 in decimal:
(1 * -2^11) + (1 * 2^7) + 2^6 + 2^5 + 2^4 + 2^2 + 2^0 = -2048 + 245 = -1803
Similarly, the value of octal 3412 in decimal is 1802.
Having obtained the two values in decimal, I subtract (-1803 – 1802), obtaining the result -3605.
Binary representation of 3605 is 111 000 010 101.
Converting it back to octal gives 7025.
This answer is wrong. It should be octal 7777 or decimal -3777.
The concept is not clear to me. Where am I going wrong?
