BBC Discovers Flying Penguins

On a day in the beginning of April a few years back, the BBC aired the following video. There’s been a new discovery in Antarctica: flying penguins.

Here’s how the video was made:

Happy April Fools day!

Todo list after installing Manjaro Linux

To enable Manjaro to use all 6 CPUs on my computer, enter this at a terminal: MAKEFLAGS=”-j$(nproc)”

Enable AUR. Search AUR for Vivaldi and Vivaldi-codecs

To open a terminal with ctrl-alt-T open Settings > Keyboard > Application Shortcuts > +Add > Command: exo-open –launch TerminalEmulator
Click OK and when asked for a keyboard command, simply press Ctrl-Alt-t

Howto – keyboard sound control finally figured out. Using pactl which allows greater than 100% sound volume.
To open a terminal with ctrl-alt-T open Settings > Keyboard > Application Shortcuts > +Add > Command:
pactl set-sink-mute 1 toggle [mutes or unmutes]
pactl set-sink-volume 1 +5%
pactl set-sink-volume 1 -10% (then reboot the computer)

Install Xscreensaver

Mouse Acceleration:
Try this:
sudo ln -s /usr/share/X11/xorg.conf.d/10-evdev.conf /etc/X11/xorg.conf.d/10-evdev.conf
Restart after making the link.
If it doesn’t work revert the change with:
sudo rm /etc/X11/xorg.conf.d/10-evdev.conf

The History of the Internet

I plagiarized everything below this paragraph from somewhere, I just don’t know where I got it from. I found it saved on my Google Drive from a long time ago. It’s interesting, so I post it here for your perusal.

The history of the Internet begins with the development of electronic computers in the 1950s. Initial concepts of packet networking originated in several computer science laboratories in the United States, Great Britain, and France. The US Department of Defense awarded contracts as early as the 1960s for packet network systems, including the development of the ARPANET (which would become the first network to use the Internet Protocol.) The first message was sent over the ARPANET from computer science Professor Leonard Kleinrock’s laboratory at University of California, Los Angeles (UCLA) to the second network node at Stanford Research Institute (SRI).

Packet switching networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of communications protocols. The ARPANET in particular led to the development of protocols for internetworking, in which multiple separate networks could be joined into a network of networks.

Access to the ARPANET was expanded in 1981 when the National Science Foundation (NSF) funded the Computer Science Network (CSNET). In 1982, the Internet protocol suite (TCP/IP) was introduced as the standard networking protocol on the ARPANET. In the early 1980s the NSF funded the establishment for national supercomputing centers at several universities, and provided interconnectivity in 1986 with the NSFNET project, which also created network access to the supercomputer sites in the United States from research and education organizations. Commercial Internet service providers (ISPs) began to emerge in the late 1980s. The ARPANET was decommissioned in 1990. Private connections to the Internet by commercial entities became widespread quickly, and the NSFNET was decommissioned in 1995, removing the last restrictions on the use of the Internet to carry commercial traffic.

Since the mid-1990s, the Internet has had a revolutionary impact on culture and commerce, including the rise of near-instant communication by electronic mail, instant messaging, voice over Internet Protocol (VoIP) telephone calls, two-way interactive video calls, and the World Wide Web with its discussion forums, blogs, social networking, and online shopping sites. The research and education community continues to develop and use advanced networks such as NSF’s very high speed Backbone Network Service (vBNS), Internet2, and National LambdaRail. Increasing amounts of data are transmitted at higher and higher speeds over fiber optic networks operating at 1-Gbit/s, 10-Gbit/s, or more. The Internet’s takeover of the global communication landscape was almost instant in historical terms: it only communicated 1% of the information flowing through two-way telecommunications networks in the year 1993, already 51% by 2000, and more than 97% of the telecommunicated information by 2007.[1] Today the Internet continues to grow, driven by ever greater amounts of online information, commerce, entertainment, and social networking.

Vivaldi – Hey I’m into it!

This is not the “Official” Vivaldi icon. I designed this one myself and it works better for my desktop. Feel free to use it for yourself. I hereby donate it to public domain.

Vivaldi is a web browser. It works for Windows, OS X and Linux. For the Linux people they have a download for DEB and RPM people. For Arch and Manjaro people, I found it in the AUR repositories. For Windows and OS X people, just download it from their site.

Watch the videos. This is not your ordinary web browser. I’m really excited about this one.

This is not an advertisement. It’s a free browser anyway. I’m just talking about it because I found it quite accidentally last night and am very happy with it.

Check out these features.

Drilling to the Center-most point of the Earth

I’m a hypothetical billionaire, so let’s discuss financing this project and the chances of success, what we’ll need to get it done, and so forth. Theoretically, it would seem possible.

At the south pole the earth is 12,715 and a half miles in diameter, or about 7900 miles to the center, but at the equator the diameter is 12,756.32 kilometers or 7,926.41 miles to the center. The earth is thicker at the equator and it would take a deeper hole to drill from there. We can make a drill 12.7 miles shorter if we drill from Antarctica. So let’s start drilling there.

From Antarctica, our drill will need to be 3,950.5 miles long to reach the center of the Earth. That’s 300 miles longer than the distance between New York and Paris.

To build a drill like that we’ll have to use a modular design. We’ll start with a shorter drill bit and keep making it longer as we drill deeper until it reaches 3,950.5 miles long.

The drill would need to be really thick and made of some really strong stuff to get through granite and just generally tough layers of rock. A drill tip with diamond heads is probably the way to go. As we drill down, the bit will get dull from time to time and we’ll have to pull the whole drill bit out to replace the head. That might have to be done several times a day.

Eventually, at some depth or other, you’re going to encounter molten rock. In the core itself is molten iron. Your drill bit will melt. All that trouble for nothing.

It doesn’t sound practical to drill to the center-most point of the earth by drilling from anywhere.

Browsers

Once in awhile on this blog I talk about Linux because as some of you know it is the operating system on my desktop computer.

What most of us do most of the time on our computers involves the Internet, so what operating system is under the hood of your computer doesn’t matter a lot. If you run Windows 10 on your computer, you’re probably surfing the Web with Internet Explorer, or maybe Firefox or Chrome Browser from Google.

Now I’m here to tell you about a really cool browser which may be the best one I have ever used across any platform. It Runs on Windows, Mac and Linux, so it’s cross platform and it’s free. It’s called Vivaldi. For downloading and trying it out you even get a free email address.

You can do interesting stuff with this browser that I haven’t seen anywhere else. You can take your browser tabs at the top and merge them. Then you can open the merged tab and get more than one web page on your screen side by side. As I write this on the left side of my screen, I have Quora.com loaded on the right, and it’s all in the same browser window.

There’s a lot of other neat stuff which you can see here:
