Using an IMG tag

<img src="path/to/image.jpg" alt="">

Setting a background

<div style="background-image:url(path/to/image.jpg)" ></div>

Using the picture tag

<picture> <source srcset="path/to/mage.webp" type="image/webp" > <img src="path/to/image.jpg" alt=""> </picture>

This will load a webp format in browser that suppport it, and a jpg image as fallback. Webp is a format that offer better compression than jpg combined with transparancy. Unfortunately it is not supported yet by Firefox or Safari.

An IMG tag is needed, the picture tag will not show anything, it will just let you set several `url` choices for image type or media selector.

Setting the background in a pseudo-element

div::before{
 background-image: url(path/to/image.jpg);
 }

Using an IMAGE tag

<image src="path/to/image.jpg" alt="">

Yes, you can use an image tag as well, this will be interpreted as `img` tag in the DOM.

Using the picture tag with an image tag

 <image src="path/to/image.jpg" alt="">
 </picture>

Setting the content in a pseudo-element

div::before{
 content: url(path/to/image.jpg);
}

Yes, you can load in image in HTML by setting to content property to an URL.

My good old Acer laptop started to smoke sitting on the couch yesterday evening.

Growing old, in cat years my laptop is an old gray tomcat, but with a SSD and some good memory, you can grow old rather vividly these laptop days. A mouse a day keeps the doctor away.

But it wasn’t smoking a cigar; the wire near the plug was short-circuited, probably all the bending in a lifetime  was suddenly to much this particular evening.

Lucky me, I saw it starting to smoke, so I unplugged it immediately. The adapter was, like any good house-cat, lying on the newspaper. Wow, my house could end up in a fire, taking a piss. So I need a new charger.

Then I started to look for a new adapter, old laptops work fine, but old batteries are suffering from age, and I couldn’t find a good fit.

All brands seems to have a specific adapter size for their chargers, so I made a table with power connector plug sizes for different laptop brands:

These are the most common ones, please let me know any mistakes or omissions.

This day had some shocking news in the morning. All Wi-Fi devices were unsafe! A serious weaknesses in WPA2, a protocol that secures all modern protected Wi-Fi networks was discovered by a Belgian security researcher.

In particular Linux and Android devices were vulnerable.

Bad news. But Ubuntu rolled out a patch and fixed the vulnerability already today.

So running this commands will make your device safe again:

sudo apt update
sudo apt upgrade

Before the update:

wpasupplicant/xenial,now 2.4-0ubuntu6 amd64 [installed]
 client support for WPA and WPA2 (IEEE 802.11i)

After the update of today:

wpasupplicant/xenial-security,now 2.4-0ubuntu6.2 amd64 [installed]
 client support for WPA and WPA2 (IEEE 802.11i)

Changelog for the update

 wpa (2.4-0ubuntu6.2) xenial-security; urgency=medium
 * SECURITY UPDATE: Multiple issues in WPA protocol
 - debian/patches/2017-1/*.patch: Add patches from Debian stretch
 - CVE-2017-13077, CVE-2017-13078, CVE-2017-13079, CVE-2017-13080,
 CVE-2017-13081, CVE-2017-13082, CVE-2017-13086, CVE-2017-13087,

 - CVE-2016-4477
 * This package does _not_ contain the changes from 2.4-0ubuntu6.1 in
 xenial-proposed.

So, it’s safe to say, software including open source software is not without faults, but at least open source software can be fixed fast, and patches can be rolled out to all devices the same day.

Happily running Ubuntu!

I would love to run Linux on my Phone.
