BitPay’s Internal Mining Pool

At BitPay we are huge proponents of open source software and of course cool gadgets! To do some of our internal testing, we built a small pool of bitcoin miners that run raspbian. Those two miners each have a powered USB hub and a few usb miners each. They are cooled by a pair of simple USB fans. All of which sits neatly on the corner of my desk! Gotta love how easy it is to deploy something like this in such a small form factor on linux… It’s reliable, fast, and just plain looks awesome sitting on my desk!

Valve games for Mesa/DRI developers

Hi,
At Collabora (my lovely dayjob), we’ve been working with Valve on
SteamOS. Valve are keen to give back to the community, and we’ve been
discussing ways they can help do that, including providing free access
to Valve games on Steam to Debian developers last year.

We’re happy to say that this has been extended to Mesa developers as
well, to say thanks for all the great work. If you have 25 commits or
more (an arbitrary number) to Mesa0 in the past five years, please
drop me an email (with ‘Steam’ in the subject) with your freedesktop
username and Steam username. We can then get you access to all past
and future Valve-produced games available on Steam[1].
Thanks for all the great work, and enjoy.
Cheers,
Daniel

Gnome 3.16 Hits

My Updated 3.16 Packages for GNOME Extensions by Michael Tunnell aka RottNKorpse

GNOME, desktop environment project, released their latest version of 3.16 recently so I decided to make an update to my previous extension package releases. I made a similar post last year for the GNOME 3.14 Release because some of my extension broke. Unfortunately, some of those extensions are still unmaintained and thus not updated for 3.16 either. So I am continuing to update some extensions for myself and anyone else who wants them.

Intel Compute Stick, world’s smallest PC, will cost $150 with Windows, $110 with Linux

Intel Atom quad-core processor, 2GB of RAM, 32GB of storage and 802.11b/g/n Wi-Fi. It plugs directly into a monitor or TV via HDMI, and is powered through a Micro USB jack on the side of the stick. There’s also a full-sized USB port, and Bluetooth 4.0 for connecting a mouse and keyboard.

Microsoft Adopts ODF

Microsoft has confirmed it will start supporting the Open Documents Format (ODF) in the next update to Office 365, following a lengthy battle against the UK government.
In 2014, Microsoft went against the government’s request to support ODF, claiming its own XML format was more heavily adopted. The UK government refutes the claim, stating that ODF allows users to not be boxed into one ecosystem.

Gnome 3.16 systemd-journal coming in next Tumbleweed snapshot

It’s official, Gnome will be in the next Tumbleweed snapshot and the development experience is highly anticipated. A clean installation works, but the guys are working on one last test before its released. We’re not promising an early Easter gift, but Tumbleweed users won’t have to wait long for Gnome’s latest upgrade.

A small change to Linux can be seen in Tumbleweed with a change from the syslog to systemd-journal; the systemd-journal as a binary file needs special tools to look at it.

systemd-journal has been in Fedora since Fedora 18

Audacity 2.1.0 Released

For a long time, we have wanted Real-Time Preview for effects.
It seemed nearly unachievable without major restructuring.
But with Audacity 2.1.0, we have it in
LADSPA, VST, and Audio Unit (OS X) effects!
Thanks to Leland Lucius for these great new capabilities!

Much improved
Noise Reduction
effect replaces Noise Removal. Thanks to new contributor Paul Licameli!

Lots of other improvements to effects, also thanks to Leland, including:

VST: FXB preset banks, hosting multiple plugins

All effects can now be used in Chains, and can be sorted on name, publisher, or class.

Most Nyquist effects now have Preview button.

Redesigned Meter Toolbars show a lot more information in smaller area. Thanks, Leland Lucius and James Crook!

Spectral Selection
in Spectrogram view. Thanks to Paul Licameli!

How to Install and Run Android Apps in a Linux OS

Basically, anyone with a computer will be able to get an APK file and get it running inside the Google Chrome browser with a minimum amount of effort. What’s even more interesting is that the app only needs Google Chrome installer, it doesn’t need it to run. If you check the background processes, you will notice that a Chrome one is running along with the Arc Welder.

Gentoo, after 10 years, has a new website! – not April Fools this time!

Blender New Version 2.74 Is Out With New Tools And Improvements

The Blenders Institute’s sixth open film

The Blender Institute’s sixth film project, codenamed Gooseberry, is in deep into the most open production from the Blender Institute yet. If you’ve been following the project so far, then you already have a sense of what Blender means by an “open production”—lots of sharing.

Crazy Science Questions | SciByte 16

chris — Tue, 13 Sep 2011 20:19:13 +0000

This week on SciByte we take a look at the weird, the wacky and the too strange to be true … except when science intervenes. We break it down and serve it up just for you, based on questions submitted by the viewers of this show!

What kind of crazy science are we talking about?

I saw a video of a floating strawberry, what’s that about ?!?

All materials have diamagnetic properties, but the effect is very weak, and is usually overcome
- Diamagnetic : repels a magnetic field

Dia … what .. ic?

Property of an object which causes it to create a magnetic field in opposition to an externally applied magnetic field by, alters the orbital velocity of electrons around their nuclei
As water is predominantly diamagnetic, this technique has been used to ‘levitate’ water droplets and even live animals; however, the magnetic fields required for this are very high and can create problems if any ferromagnetic materials are nearby
- The fields required are typically in the range of a little over 10.5 times more powerful than a typical MRI machine 16 tesla
Video’s of objects floating in strong magnetic fields

Speaking of the crazy visuals science provides us …

Why does a cloud appear around sonic boom and what IS a sonic boom

First some cools pics and videos in case you haven’t seen these!
Sonic Boom Cloud pics

Like a crowded convention floor, even sound can only move so fast

Sound travels at ~ ‘760 mph / 340 meters per second ‘
When an object passes through the air it creates pressure waves in front of and behind is, similar to the waves by a boat
Also similarly the faster the object travels the closer the waves are forced together
- Think crowd movement towards awesome free swag
At a certain point those air waves are compressed to such a degree that they can not get out of the way of each other
- Eventually they merge into a single shock wave, this critical speed is known as Mach 1
- Mach 1 ~ 761 mph ~ 1,225 km/h
When this shock wave passes, a listener hears all at once the sound emitted over a longer period: a sonic boom

The more you know! … about sonic booms and the first invention to break the sound barrier

The whip was probably the first human invention to break the sound barrier.
The cracking sound a bullwhip makes when properly wielded is, in fact, a small sonic boom.
The end of the whip, known as the “cracker”, moves faster than the speed of sound, thus creating a sonic boom.

That crazy cloud thing …

The origins of this cloud is still debated but there are long standing theories.
Rapid condensation of water vapor due to a sonic shock produced at sub-sonic speed creates a vapor cone

Traveling faster than sound in a circle round the world

Why are there 360 degrees in a circle?

There are a few theories about the origin, but the precise reason is unknown

The hand, more than just counting to 5 …

Using your thumb you can count to 12 on each hand using each finger bone. ( This is still used in many regions of Asia )
Also ‘12 bones on each hand, 2 hands = 24 hours in one day’

The kind of math you’ll never forget … Sexagesimal (base60)

Some ancient societies used Sexagesimal (base 60) math, but how did they get there?
- Remember counting to 12 on one hand … ‘12 finger bones * 5 fingers = 60’
Originating in ancient Sumerians, it was passed to ancient Babylonians and is still used in a modified form ( for measuring time and angles )
We still use it today with time and latitude
- 1 hour = 60 min; 1 min = 60 sec
- There are 60 minutes of arc in a degree, and 60 arcseconds in a minute.

Days in a year Theory

Ancient astronomers noticed that the stars in the sky advanced in their yearly trek around the sky by approximately 1/360 of their path each day.
- The ancient Persian calender used 360 days per year, why 360? it’s that crazy base 60 math again

Equilateral Triangle Theory

An equilateral triangle is a triangle with all equal side lengths
The earliest trigonomety was used by Babylonian astronomers and their Greek successors
1/60 (remember that crazy Sexagesimal math? I knew you would) of an equilateral triangle is the same as 1 degree or 1/360 of a circle

Actually 360 is easy on the math too …

360 is readily divisible, it was 24 divisors
- An integer which divides a number without leaving a remainder.
24 time zones (15* per section) 24 hours in a day

Does science know that black holes are really real (i.e. 100% certainty) or its more like “we are sure for 90% that black holes exist”?

Due to their very nature, we cannot directly observe Black Holes.
Observations and math provided the [first evidence for black holes](https://www.damtp.cam.ac.uk/research/gr/public/bh_obsv.html although the idea has been around
- Einstein’s general theory of relativity (published in 1916) predicts just the kinds of object we are now inferring
- the first object to be generally recognized as a black hole is the X-ray binary star Cygnus X–1 as early as the 1970’s

Looking for what you can’t see

The extreme gravitational forces of a black hole warp space and time so much, that even light can not escape
- You can not observe them directly in the same you we observe stars or galaxies, since they don’t give off light
We can observe the effects of how they warp space and time

You can check in any time you like, but pass the event horizon, and you can never leave

Some recent observations using X-Ray Binary Observation compared energy outputs from a specific set of star systems.
- In one set, were Neutron Stars, which are the densest stellar objects (other than quasars and black holes)
- In the other set, Black Hole Candidates (unproven massive objects)
- Both sets were companion systems, where another star was orbiting the massive object in question.
The energy emissions of each set were vastly different
- Neutron Star : Energy and matter falling in tends to impact the object at the center, and emit energy at a high rate
- Black Hole Candidates : Energy and matter falling in had almost zero energy emission
- Comparison picture

When math bends time and space

Hawking Radiation…
Explaining what it is, is highly complicated. But suffice it to say that Steven Hawking proposed a theory that holds up to mathey scrutiny, indicating that Black Holes should emit a very specific amount of thermal radiation, which is inversely proportionate to their total mass.
- In other words, the bigger the black hole, the less of this Hawking Radiation it emits, but it never reaches a point of zero emission.
Since all black hole candidates that we have currently observed are generally incredibly massive, detecting this tiny amount of Hawking Radiation is very difficult.
However, a certain type of “Primordial Black Hole” (relatively low on mass) can sometimes collapse in on themselves, generating a massive burst of Hawking Radiation.
- In 2008, NASA’s [Fermi Gamma-Ray Telescope](https://fermi.gsfc.nasa.gov/ was launched, which includes searching for these ancient explosions as part of their purpose.

Do tachyon particles really travel backwards in time??

Tachyon : a hypothetical subatomic particle that moves faster than light
Because a tachyon moves faster than light, we cannot see it approaching.
- After a tachyon has passed nearby, we would be able to see two images of it, appearing and departing in opposite directions. GIF

When the strange gets stranger

Unlike ordinary particles, the speed of a tachyon increases as its energy decreases. In particular
Since time travel is considered to be non-physical, tachyons are believed by physicists to either not exist, or else to be incapable of interacting with normal matter

The answer was 42 … but what will the question be?

Special relativity implies that tachyons, if they existed, could be used to communicate backwards in time, in a process called Tachyonic antitelephone
Welcome to causality violations, and answers before you ask the question
So I guess when we get beamed the answer, we’ll start to wonder what the question was.
