I haven’t been using Opera for quite a while as I didn’t really have a need for a third browser lately (Firefox & Chrome being the main ones). However I came across this article today mentioning that Opera has integrated ad-blocking as a core feature rather than a plugin to manage.

If there were no bloated ads, some top websites would load up to 90% faster.

Today, we wanted to share with you a native ad-blocking technology in our Developer channel for Opera for computers. “Native” means unmatched speed vs extensions, since the blocking happens at the web engine level.

Whilst there is a .DEB installer to download from the GoHugo sites I get all matter of warnings that the package is of bad quality and I am not comfortable to run these kinds of installers.

I rather install from sources in this case which is very straight forward since the main dependencies (largely GO) are in the Ubuntu main repositories.

Install dependencies

sudo apt-get install golang git mercurial python-pygments

As a long-term Ubuntu user I am extremely interested in what Canonical and the Ubuntu community are doing on the mobile front. Their convergence strategy (I am testing Snappy Core on IoT devices as well) seems very well thought through and once the the Meizu MX4 phone was released I got myself an invite and ordered a unit. It took a while to ship and then also had to make it’s way down under as Meizu only ship to Europe (and Asia I believe).

One of the things that is not implemented in the Secure Shell Chrome extension is the ability to remove know_host fingerprints which alert you if the fingerprint for a specific IP address has changed.

However there are times when you upgrade a systems and this need to be done.

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Synology NAS systems are great VPN servers for a home or small office. However if you want to connect to the VPN and route all your traffic through the VPN and be able to browse the internet there are a few things you need to change on the Synology server.

Theoretically you should be able to set these options on the client, but I have not managed to get this to work with Synology and judging by the amount of forum threads a lot of other people had the same problem. If somebody has a better way to fix this I would love to know. I don’t like to manually change these config files as I assume they will be overwritten when making changes to the web-interface.

Unfortunately it is still much harder than necessary to find notebook hardware to use with Ubuntu (or other Linux variants). This blog is full of past experiences (some of them quite time-consuming) on finding notebook hardware that will work without too much fiddling. This short note is to document my recent research on that front to help others who want to do the same (as there doesn’t seem to be a lot of good current info around).

Every once in a while you find a gem. One of these for me is SShuttle – until now I have not known about this one.

Use-case: I just been trying to get Ubuntu Make to install Eclipse IDE and the local AARNET download mirror is just refusing to cooperate (https://github.com/ubuntu/ubuntu-make/issues/90). A quick forward to a remote VPS fixed the issue without headaches

Add SDK repository

sudo add-apt-repository ppa:ubuntu-sdk-team/ppa

sudo apt-get update sudo apt-get install ubuntu-device-flash`

Enable USB Debugging on the device

1. Make sure you have developer mode enabled (see http://developer.android.com/tools/device.html if you are unsure).
2. Navigate to Settings > Developer options
3. Enable USB Debugging. When a device is connected, you will be prompted in Android to authorize it.

Unlock Bootloader

adb reboot bootloader

fastboot oem unlock fastboot reboot`

Raspberry Pi Prerequisites

Since this will be a purely headless install designed to sit in a corner behind the scanner I am using a Base Raspian (Debian Wheezy) install (I personally like the clean minimal install via https://github.com/debian-pi/raspbian-ua-netinst the best).

There are plenty of sites out there that give advise on this topic, unfortunately most of them are highly ad-infested to the point of being unreadable as well as only containing single bit rather that an overall picture. This is a collection of useful links to source materials as well as steps necessary to install.

Just a quick update of the previous article on “Sony Xperia Z2 upgrading to CyanogenMod 11“.

One thing is that CM now included the custom recovery and you do not need to download any other custom recoveries !

Download the CM 12 ZIP file for Sony Xperia Z2 (sirius) and extract the ‘boot.img’ file

Download link: https://download.cyanogenmod.org/?device=sirius

Get the device into fastboot (bootloader mode)

On remote systems sometimes a web-based tool can be very handy. Webmin is such a tool that has been well maintained for decades. To install quickly on a Ubuntu Server without having to manage dependencies and keeping it updated as part of normal OS update operations installing from a PPA Repo is handy.

sudo echo "deb http://download.webmin.com/download/repository sarge contrib" >> /etc/apt/sources.list

wget -q http://www.webmin.com/jcameron-key.asc -O- | sudo apt-key add - sudo apt-get update sudo apt-get install webmin`
