We believe it would be unethical for us to give funds to a third-party company without knowing where those funds are going, and knowing a large portion is going to administrative waste. In the case of open-source projects that Viscosity uses we're committed to directly supporting these projects where possible. It's not something we'd normally discuss publicly, however we chose not to support them financially as a significant undisclosed (edit: disclosed below) portion of donations goes to "administrative costs" and pay "bonuses".Īs a small indie company we're extremely grateful to every single user for supporting Viscosity, and so we have an obligation to spend the money they so generously give us on efforts that will support Viscosity and its community. On a more sombre note, I'm saddened that OSTIF feel the need to disparage Viscosity because we opted not to respond to an unsolicited email request for money.
For those interested you can search for commits and discussion under our developers names (which can be found on our company page).

We have contributed to open-source projects and initiatives we feel are beneficial, both via source code contributions (which includes OpenVPN), financial donations (which includes the TunTap project), and advice/discussion (a large assortment). It is also incorrect to say that we "do not contribute back to the project through commits nor financially". For those interested please see the comment linked above for more information. Indeed, any Viscosity user is welcome to email us for GPL covered source-code, as evidenced in Viscosity's EULA. As anyone familiar with the open-source OpenVPN project knows, OpenVPN is licensed under the GPL, which mandates that original source code, and the source code for any changes, be made available. It is incorrect to say that "closed source fork of an open source project". Piggy-backing off my comment above, I've included some points below to help address some misleading comments in this thread: I also recommend checking out an old Reddit comment of mine which answers a similar question and goes into some more depth regarding Viscosity, OpenVPN, and open-source: I'm sure you'll love Viscosity, as we've poured heaps of effort into making Viscosity as powerful and trouble-free as possible, but again, I encourage you to give it a try for yourself. Viscosity can be freely used for 30-days, at which point you can register it if you like it or simply delete it if you prefer something else. I encourage anyone reading this looking for an OpenVPN client to try out all of the above clients. Popular OpenVPN clients include the OpenVPN Community GUI (Windows only, and considered the only "official" client), Tunnelblick (Mac only), the OpenVPN Connect Client (Mac & Win), and of course Viscosity (Mac & Win). Because of this a comparison of "Viscosity or OpenVPN" doesn't exactly make sense :) For those unfamiliar, by "OpenVPN" in this case the OP means another VPN client that supports OpenVPN. OpenVPN is a type of VPN protocol, which Viscosity supports. Thought I'd jump in and try and offer some insight! The novel viscosity determination technique opens a new field of fluid characterization in extreme operating conditions.Viscosity developer here. By comparisons with computations for multi-species mixture, even multi-phase, a reasonable agreement is found. The method has been applied to liquid dodecane (from 300 to 700 K and up to 60 bar) with the same order of accuracy before testing it on supercritical n-dodecane (658–700 K up to 60 bar) for which no validation data have been found. The main source of uncertainty is found to be linked to the characteristics of sensors. The accuracy of the methods can be as low as 5% by comparison to National Institute of Standards and Technology data. First tests have been realized with pure gaseous nitrogen at ambient then high temperature (1200 K) for several varying pressures (up to 60 bar). The Darcian law or the Darcy–Forchheimer equation are used depending on the flow regime. The novel approach proposed in this paper is based on fluid permeation through characterized porous media. Its experimental estimation for multi-species and/or supercritical hydrocarbon mixtures under high temperature and pressure remains quite absent. Its determination can be based on experiments with viscometer and on calculations for single or multi-species components, possibly through the use of mixture law and other intermediate parameters. Viscosity is an OpenVPN client for Mac which gives a rich Cocoa graphical user interface for creating, editing, and controlling VPN connections.
The kinematic viscosity is a major physical property to be used in numerical, experimental and analytical work in all the related fields of fluid flow research. There's not much you can do to make a VPN more attractive to use but the makers of Viscosity have given it a very good go.
