Level 50 compared to other OS

May 16, 2022

This is our ranking of the Cosmic Dolphins: LvL 50 in comparison with other OSs:

  1. Cosmic Dolphins: LvL 50
  2. Lineage OS (without google): LvL 40
  3. Apple IOS: LvL 31
  4. Android OS: LvL 29


Android OS: LvL 29

Positives: Open source system, so flaws are scanned and fixed quickly. The closer you use a phone
to the “pure” Android version, the faster you will get security updates.

Negatives: Google takes all your information. If it’s used by another manufacturer like Samsung,
Oppo, Huawei, Xiaomi etc. the manufacturers also take your data, and all of them resell your
information to third parties.
Users can install almost anything and thus put themselves in a situation to be hacked.
The system is installed on the vast majority of phones in the world, so it will be more easily targeted
by hackers since there are more potential targets.

Apple IOS: LvL 31

Positive: The operating system does not allow the user to install anything that has not been
validated by Apple (a law has been passed in Europe and Apple will soon be forced to let the user
install applications that have not passed their “scanner”).
The system is used on fewer devices so it won’t necessarily be the primary target of hackers.

Negatives: Apple makes a point of not letting anyone else take your data, it’s to be able to better use
and sell them, they know absolutely everything, except that their system is closed so we can’t see
anything they do.
The system is completely closed, so the flaws take longer to be found and fixed.

Lineage OS (without google): LvL 40

Positives: No Google, no Apple. A simple, efficient and open source system. Few phones offer it so
it is not a priority target for hackers. Updates are offered very regularly.

Negatives: You don’t have access to your usual applications. You have to install it yourself on a
phone so if it is compromised at the hardware level, the user could not realize it. Not very easy to
install for the uninitiated. If the user does not install the OS correctly, additional vulnerabilities are
created. For example, in case the bootloader is not locked after installation, this could be a security
hole (for the initiated).

Cosmic Dolphins: LvL 50

Positives: No Apple. There are Google applications but they are installed directly in the safe box,
apart in the phone. All the info that Google collects and the apps from the Playstore are fake. All the
applications that are not considered trustworthy are directly installed in this safe box. The system is
open source.

Negatives: As far as the user can install applications linked to Google, he can voluntarily give his
private data and therefore remains a security hole.

Which free open source VPN to choose?

April 6, 2022

Here we like open source. It is often a guarantee of quality, security and integrity. And fortunately, there are free open source VPNs! The advantage is that you can use them when you travel and when you don’t have too sensitive data to protect. Otherwise, opt for a more solid alternative like Mullvad or ProtonVPN premium.

In short, try to value open source VPNs where the source code writing and maintenance is done by a community of volunteer developers. In a way, open source VPNs are more reliable because of the independent security audit (everyone can freely study the VPN operation to find any security flaw).

In the lot, we can mention OpenVPN, ProtonVPN or Riseup VPN.

VPN client, VPN network or both?

Before going into the presentation of the solutions, it is important to understand what we choose when we install a VPN. There are several possibilities:

  1. Install a VPN client (application) and configure it with a specific VPN server (not necessarily linked to the application). You can even configure your own VPN server at home…
  2. Install a VPN client automatically linked to the VPN servers of the company that coded the client.

Here the second solution is the easiest technically because you won’t need to set up the application. It might ask you to choose the destination country of the VPN server you want, but that’s basically it. In the first option, you will have to set the network information of the VPN server in order to adjust the communication between your computer and it.

So once we know that, we know that there are several aspects: the client (the application) must be open source and the system on which the VPN servers run too. In any case, you have to trust the owner of the VPN server to be sure that he doesn’t exploit your data.


OpenVPN is available on almost all platforms (Windows, Mac, Android, iOS, Linux, etc.). Today it is among the most popular open source VPN solutions due to its ease of use and reliability in terms of security. Different offers exist from self-hosting to all-inclusive premium offers.

The OpenVPN software client has been known for years as reliable. However, it starts to be outdated by Wireguard which offers the use of other faster network protocols. Personally I use OpenVPN with custom settings like Proton servers or my home server.


ProtonVPN is a freemium software available on Windows, Mac, Android and iOS and its network consists of more than a thousand servers around the world. With the same basics as OpenVPN and the AES256 symmetric encryption algorithm, the ProtonVPN client is a very good open source alternative offering great performance and reliability even for its free version.

Little bonus, Proton claims not to store logs of its VPN servers, so theoretically they don’t know what transits through their servers. Marketing or reality? We can’t be sure because their server code is not open source. Only their application is.

I recommend using ProtonVPN with an OpenVPN or Wireguard client on Linux for example. It is very efficient and adds a layer of security and you will have full control over the application. ProtonVPN explains how to do it, just follow the procedure.


RiseUpVPN is a VPN service offered by a community of independent developers. Still in its beta-test version, it has an easy-to-use client software that you can download for free from the official website.

I also use BitMask on Android (which is opensource) by selecting RiseUp Networks as default VPN. It allows me to have a quick VPN on my phone without any hassle and totally free!

Once again, let’s take the time to thank this extraordinary community of open-source developers, often volunteers, who prove that profit is not the only trigger of human creation.
