PayPal

In spite of its international reach, PayPal has limited functionalites for multi-country users, most notably the impossibility to have bank accounts in several countries, or to have a shipping address in a different country than one's bank account / credit card.

BitTorrent protocol

http://en.wikipedia.org/wiki/BitTorrent_%28protocol%29

BitTorrent is one of the most common protocols for transferring large files, and peer-to-peer networks have been estimated to collectively account for approximately 43% to 70% of all Internet traffic (depending on geographical location) as of February 2009

Deluge

When you know you've finished with a torrented file, better to remove it, or Deluge will try to start it whenever you fire it up.

Google Calendar

http://en.wikipedia.org/wiki/Google_Calendar

It's so handy if you've Android devices, and easy to use, except searching, or getting stuff out of it ain't as straightforward as it seems. My preference is to:

  1. go to an Agenda view
  2. More > Print
  3. tick on Print descriptions - they're always off, and I always want them on
  4. for Range first select a start date, then an end date
  5. (this is a configuration: Print > Destination > Save as PDF then Cancel)
  6. Save As - which gets a pdf, nicely named by the date range.
  7. Cancel (to get out of the Calendar Print Preview dialog)

Keyboard shortcuts https://support.google.com/calendar/answer/37034?hl=en

navigate:

  • j or n for next date range
  • k or p for previous
  • t for today

I set mine for 3 week custom view, then:

  • a = agenda
  • m = month view
  • x = custom view

Time zones are switched intelligently.

Google Drive

  • folder upload works fine if you're accessing it from Chrome, but from Firefox you get a limited functionality only if you install a Java applet (which my version of Java claimed was insecure).
  • http://en.wikipedia.org/wiki/Google_Drive My Drive You access with your gmail address, and get 15GB of online storage for free!
  • Google Photos is where many can be selected and dragged to the Bin.
  • sharing stuff is what I mostly use it for. Big upload filesize limit (10GB last time I looked) so you can put a huge encrypted zip there, if you've got the broadband upload capacity. You get a link for the shared folder, and anyone who goes to that link can easily download the contents without having to sign in.

Infrastructure Technologies

Hypertext Transfer Protocol

HTTP functions as a request-response protocol in the client-server computing model. A web browser, for example, may be the client and an application running on a computer hosting a web site may be the server. The client submits an HTTP request message to the server. The server, which provides resources such as HTML files and other content, or performs other functions on behalf of the client, returns a response message to the client. The response contains completion status information about the request and may also contain requested content in its message body.

MAC address

https://en.wikipedia.org/wiki/MAC_address

A media access control address (MAC address), also called physical address, is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi. Logically, MAC addresses are used in the media access control protocol sublayer of the OSI reference model.
MAC addresses are most often assigned by the manufacturer of a network interface controller (NIC) and are stored in its hardware, such as the card's read-only memory or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address (BIA). It may also be known as an Ethernet hardware address (EHA), hardware address or physical address. This can be contrasted to a programmed address, where the host device issues commands to the NIC to use an arbitrary address.
The original IEEE 802 MAC address comes from the original Xerox Ethernet addressing scheme. This 48-bit address space contains potentially 248 or 281,474,976,710,656 possible MAC addresses.

RSA (cryptosystem)

In such a cryptosystem, the encryption key is public and differs from the decryption key which is kept secret. In RSA, this asymmetry is based on the practical difficulty of factoring the product of two large prime numbers, the factoring problem. RSA is made of the initial letters of the surnames of Ron Rivest, Adi Shamir and Leonard Adleman, who first publicly described the algorithm in 1977.

Transport Layer Security (TLS)

Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), are cryptographic protocols designed to provide communication security over the Internet.
The TLS protocol allows client-server applications to communicate across a network in a way designed to prevent eavesdropping and tampering.

Uniform resource locator (URL)

The Web is indexed with crawlers that look at URLs

(also known as web address, particularly when used with HTTP), is a specific character string that constitutes a reference to a resource.

Internet media type

http://en.wikipedia.org/wiki/Internet_media_type - developed from Multipurpose Internet Mail Extensions (MIME)

MIME

http://en.wikipedia.org/wiki/MIME

(Multi-Purpose Internet Mail Extensions) is an extension of the original Internet e-mail protocol that lets people use the protocol to exchange different kinds of data files on the Internet: audio, video, images, application programs, and other kinds, as well as the ASCII text handled in the original protocol, the Simple Mail Transfer Protocol (SMTP).

Base64

http://en.wikipedia.org/wiki/Base64

Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding.
Base64 encoding schemes are commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with textual data. This is to ensure that the data remains intact without modification during transport. Base64 is commonly used in a number of applications including email via MIME, and storing complex data in XML.

MHTML

MHTML, short for MIME HTML, is a web page archive format used to combine resources that are typically represented by external links (such as images, Flash animations, Java applets, and audio files) with HTML code into a single file. The content of an MHTML file is encoded as if it were an HTML e-mail message, using the MIME type multipart/related. The first part of the file is normally encoded HTML; subsequent parts are additional resources identified by their original URLs and encoded in base64. This format is sometimes referred to as MHT, after the suffix .mht given to such files by default when created by Microsoft Word, Internet Explorer, or Opera. MHTML is a proposed standard, circulated in a revised edition in 1999 as RFC 2557.

Internet Protocol Suite

http://en.wikipedia.org/wiki/Internet_Protocol_Suite

The Internet protocol suite is the networking model and a set of communications protocols used for the Internet and similar networks. It is commonly known as TCP/IP, because its most important protocols, the Transmission Control Protocol (TCP) and the Internet Protocol (IP), were the first networking protocols defined in this standard. It is occasionally known as the DoD model, because the development of the networking model was funded by DARPA, an agency of the United States Department of Defense.

You don’t have IPv6, but you shouldn’t have problems on websites that add IPv6 support.

DHCP

Dynamic Host Configuration Protocol

is a standardized networking protocol used by servers on an IP network to allocate IP addresses to computers. The purpose of DHCP is to automate the IP address configuration of a computer without a network administrator. IP addresses are typically selected from a range of assigned IP addresses stored in a database on the server and issued to a computer which requests a new IP address. An IP address is assigned to a computer for a set interval, after which, the computer must renew the IP address or acquire a new one.
After the client obtains an IP address, the client may use the Address Resolution Protocol (ARP) to prevent address conflicts caused by overlapping address pools of DHCP servers.

IPv4

Address exhaustion

http://en.wikipedia.org/wiki/Dotted_decimal

For example, the address of the loopback interface, usually assigned the host name localhost, is 127.0.0.1. It consists of the four binary octets 01111111, 00000000, 00000000, and 00000001, forming the full 32-bit address.
