![]() The box provides messages about recent activity that the administrator may want to investigate or take note of. An “Administrator Advisory” box has been added to the Rumpus control window.The main control window in the Rumpus for Mac application has been updated to include easy access buttons to Web administration on the server, documentation, and the About Box.Upload Center forms now offer “robot protection”, blocking suspected robots from submitting forms.The administrator can now require that drop ship senders assign a password to drop shipments.User Accounts can now be assigned a phone number, for informational purposes and potentially for text message-based 2 Factor Auth.Rumpus 8.2 includes better support for client IP address detection, including discovery of client addresses in SFTP, and in HTTP/HTTPS when the server is behind a proxy.(Rumpus must know the e-mail address of every user, as this is a key component of identifying the user via PIN.) Also required is correct SMTP setup on the Network Settings window, E-Mail tab, and the e-mail address of every user defined on the User Accounts window. Two factor authentication is available for Web File Manager logins, and is configured on the Web Settings window, “Authentication” tab. ![]() Rumpus currently directly supports e-mailing the PIN to the user, thus confirming that the user not only knows the correct password, but also has access to the e-mail account associated with the user account in Rumpus. The second “factor” supported by Rumpus requires that a personal identification number (PIN) be sent by the server to the user logging in, which they subsequently enter as part of the login process.This is known as “2 factor” authentication. The password represents one “factor”, but in some cases, it is desirable to have a second method of authenticating a user as well. Traditionally, users supply a password to gain access to restricted services.But the conclusion follows, that both Shannon and differential entropy is unitless. That rises a problem, while $p(x)$ certainly is unitless, since probability is an absolute number, the density $f(x)$ measures probability pr unit of $x$, so if unit of $x$ is $\text$. Again, from general principles (see lognormal distribution, standard-deviation and (physical) units for discussion and references) the arguments of transcendental functions like $\log$ must be unitless. This leaves us with the unit of measurement of $\log p(x), \log f(x)$ respectively. Now, from general principles the unit of measurement of the expectation (mean, average) of a variable (random or not) is the same as the unit of measurement of the variable itself. Where $f$ is the probability density function of a continuous random variable. ![]() Where $p$ is the probability mass function of a discrete random variable. Some details: We treat Shannon (discrete) and differential (continuous) entropy separately. A measurement of length in meters can be written in decimal or binary, that does not really change the unit of measurement of length used. ) in the physical sense, it corresponds more to writing the measurement in decimal or binary number systems. ![]() But these are not really measurements units (like meter, kg. First, sometimes units are given as "nats" or "bits", for the cases of use of natural logs/binary logs, respectively. Still, there are some details to elaborate. Gave the answer in comments, entropy is unitless.
