  • Как изобразить кривые Ламе в octave или matlab?

    @D_dMer 
    %Суперэллипс
%clear all;
m=1;
n=1/2;
a = 10;
b = 10;
f = 0:pi/360:2*pi;
%f = 0:pi/180:pi/2;
x = (cos(f).^(2/n)).*(a*sign(cos(f)));
y = (sin(f).^(2/n)).*(b*sign(sin(f)));
%figure()
plot(x1, y1, x, y)
grid on
axis equal
xlab = xlabel('Ось абсцисс Х');
ylab = ylabel('Ось ординат Y');
title('Кривые Ламе');

  • Отваливается сеть на ESXi 6.7 периодически. Как диагностировать?

    @D_dMer
    Друзья, и ведь удалось же наверное решить проблему. Поделитесь методом?
    Был один провайдер, подключили второго. Купили Сетевую карту Intel Original (EXPI9301CTBLK 893647). Воткнули, все закрутилось, связь заработала, но спустя некоторое время сеть пропадает.
    В разделе "Physical NICs" статус нового интерфейса меняется с "1000 Mbps, full duplex" на "Link down".
    После перезагрузки сервера связь восстанавливается, но спустя некоторое время опять пропадает.
    в /var/log/vmkernel.log такая запись:
