How to run Epiphany (Web) Browser in Windows 10 with WSL

Epiphany (Web) is a lightweight Linux-only web browser based on the modern WebKit engine, and it is the default web browser in GNOME desktop environment. However, now you can run it natively in Windows 10, thanks to the Windows Subsystem for Linux (WSL) and the Xming X server for Windows.

Here is how to install Epiphany 3.12 in Windows 10:
  1. Install Windows Subsystem for Linux and reboot the computer
  2. Install Xming X server for Windows
  3. Open Windows Command Prompt and run: bash
  4. Run these commands in bash:
    sudo apt-get install software-properties-common
    sudo add-apt-repository ppa:gnome3-team/gnome3
    sudo add-apt-repository ppa:gnome3-team/gnome3-staging
    sudo apt-get update
    sudo apt-get upgrade
    sudo apt-get install epiphany-browser gnome-keyring gnome-themes-standard
    sudo sed -i 's/<listen>.*<\/listen>/<listen>tcp:host=localhost,port=0<\/listen>/' /etc/dbus-1/session.conf
    sudo sed -i 's/Ambiance/Adwaita/' /etc/gtk-3.0/settings.ini
  5. Right-click on your desktop and create a new shortcut for the following item:
    bash -c "DISPLAY=:0 NO_AT_BRIDGE=1 epiphany-browser"
    with the following icon (click it to download the ico file):
    Epiphany web browser icon
  6. Check if Xming is running in the system tray and double-click the newly created shortcut. Epiphany window should appear:

UPDATE: By upgrading the WSL from Ubuntu 14.04 to 16.04, you can have the latest Epiphany 3.20 using WebKitGTK+ 2.14 on Windows 10, which scores 386 points in HTML5 Test:

K-Meleon vs QupZilla vs Otter Browser vs Midori - comparison of lightweight web browsers

Apart from the most popular web browsers for Windows - Google Chrome, Mozilla Firefox, Opera, IE and Edge - there are also more lightweight open source web browsers, which deserve more recognition. This time I am testing the latest versions of four of them: K-Meleon 76.0 beta 3 (based on Gecko), Otter Browser 0.9.10 (based both on QtWebKit and on QtWebEngine), QupZilla 1.8.9 (based on QtWebKit) and Midori 0.5.11 (based on WebKitGTK+), on a PC with Windows 8 and 2 GB RAM. In the comparison test I am focusing on HTML5 features, performance and RAM usage at startup and after loading four big websites in tabs.

Here are the results:

K-Meleon Otter QtWebKit Otter QtWebEngine QupZilla Midori
HTML5 Test 467 pts 399 pts 525 pts 400 pts 341 pts
Octane Benchmark 5915 pts 1222 pts 6653 pts 1285 pts 806 pts
BrowserMark 1590 pts 1165 pts 1926 pts 1052 pts 149 pts
RAM at startup 35 MB 12 MB 54 MB 40 MB 40 MB
RAM at 4 tabs 151 MB 335 MB 236 MB 395 MB 271 MB

The best alternative web browser is Otter Browser with QtWebEngine (based on Chromium), made by a Polish developer Emdek. This is the only multi-process web browser out of them and has a really good performance. The second place goes to K-Meleon. That said, QtWebEngine is still in the works, so it may be buggy, and it uses more memory than Gecko engine used in K-Meleon.

Ziproxy vs Janus vs PageSpeed Module - comparison of compression proxies

Only 27% of the global population has access to a fast internet (over 10 Mbps) and hundreds of millions of people around the world have a limited Internet connection. This is where a data compression proxy (a.k.a. web accelerator) comes to the rescue. It optimizes loading of web pages by minimizing HTML/CSS/JS, enabling gzip compression, re-encoding images, etc.

Some time ago I was comparing proxies in the cloud: Mozilla Janus, Opera Turbo and Google Compression Proxy. Now I am testing open source HTTP forwarding proxies: Ziproxy, Mozilla Janus and Google PageSpeed Module (mod_pagespeed) for Apache with mod_proxy, all installed on my premise. This time the primary factor is not loading time, but total size of various web pages.

The best compressing HTTP proxy is Ziproxy with 25% of data savings. The second place goes to Google PageSpeed with 19%. Mozilla Janus was the worst with only 11% saved.

All the proxies were tested with equal image quality settings (60%).

Phoenix OS - Android for x86 Desktop PC with Stardust Browser

While everybody is talking about Remix OS, there is another free Chinese Android distribution for a desktop PC based on Android-x86 called Phoenix OS. It is still in the beta stage, although it should run on most of 64-bit x86-compatible machines. Just write the downloaded ZIP file to a USB drive using USBMaker and boot a PC from it. There is also an ARM version of Phoenix OS and a 32-bit version should be available soon.

Phoenix OS is based on Android Lollipop 5.1.1 and Linux kernel 4.0.9 with support for OpenGL ES 3.0. It runs Android packages (APK) and it has a few of them pre-installed, like Stardust Browser based on Chromium 45 and WPS Office. The rest you can download from Google Play Store, F-Droid, Mobogenie or Aptoide.

Here are some screenshots from Phoenix OS 1.0 Beta:

Slack is so slow! Here are 5 lightweight open source alternatives

Slack is a popular communication soft bloatware for teams. It allows you to chat with other users, groups and in channels (rooms), like good old IRC. However, the main issue with Slack is that is it way too bloated and loads too slowly. It takes 105 requests, 18 MB of data and 30 seconds to load!

So if you are concerned about your data plan, performance, or security of your business correspondence stored on third party servers, you should consider one of the lightweight open source web alternatives for Slack:

Let's Chat - loads in ~5 seconds:

JabbR - loads in ~8 seconds:

Candy - loads in ~5 seconds:

Echoplexus - loads in ~6 seconds:

Shout - finally a web IRC client, loads in ~5 seconds:

Each of them is open source, so you can install it for free on your private server and keep your internal business communication secure.

UPDATE: There is a new project called Mattermost - check it out!

Run desktop apps, WebKit and Chromium web browser on Firefox OS!

Firefox OS is a fully open source mobile platform, but it lacks many full-featured apps. Starting from today, RollApp provides full desktop apps for Firefox OS, including LibreOffice,, Tomboy, KeePassX and File Roller. The apps are loaded on RollApp cloud servers and are streamed using WebSockets, which make them run smoothly.

You can even run the Web browser, powered by WebKit, which you can start by typing any URL in Tomboy and clicking on it.

The Web browser is really fast, it gets 6568 points in the Octane benchmark.

UPDATE: Now you can run Chromium web browser in Firefox OS! It scores 9677 points in the Octane benchmark.

All RollApp apps can be found in the Firefox Marketplace.
