76543210 - Изброяваме го в обратен ред
2(7)2(6)2(5)2(4)2(3)2(2)2(1)2(0) - Степенуваме 2(тъй като ще преобразуваме от двойчна система) по всяко от позицийте
128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 - Това е резултата
0 + 64 + 0 + 16 + 0 + 4 + 0 + 1 - Събираме всички получени числа които отговарят на единица(1) в бинарното число. 
85 - полученият резултат е в десетичен вариант.

You may receive a response such as this when running Nginx and php-fpm after a fixed amount of time (default = 60s).

 Connection timed out

[error] upstream timed out (110: Connection timed out) while reading upstream, client: x.x.x.x, server: host.tld, request: "POST /script.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", ...

The “Connection timed out” usually happens when running large scripts, that need a lot of time for processing – such as import jobs parsing large XML or CSV files. The problem is that Nginx waits by default for 60s on the fastCGI response. If it takes too long, the request is stopped. The “Connection timed out” error means that Nginx hit a timeout before it received a response from the FastCGI backend.

You can change the time Nginx waits for the FastCGI backend, by changing the fastcgi_read_timeout parameter in the general nginx.conf.

Certificates and Encodings

At its core an X.509 certificate is a digital document that has been encoded and/or digitally signed according to RFC 5280.

In fact, the term X.509 certificate usually refers to the IETF’s PKIX Certificate and CRL Profile of the X.509 v3 certificate standard, as specified in RFC 5280, commonly referred to as PKIX for Public Key Infrastructure (X.509).

To enable anti-aliased fonts just for Netbeans, add -J-Dawt.useSystemAAFontSettings=on to the end of the netbeans_default_options line in /usr/share/netbeans/etc/netbeans.conf e.g.:

netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-Dawt.useSystemAAFontSettings=on"

 Alternatively, you can set this globally so that all AWT apps are affected, by setting the _JAVA_OPTIONS environment variable in your .bash_profile:
 
 export _JAVA_OPTIONS='-Dawt.useSystemAAFontSettings=on -Dswing.aatext=true'
 
  This also has Swing equivalent, using the swing.aatext preference. You'll have to log out and log back in for this to take effect.
