SwiftPM dependencies
- CBLAS-Linux (only for Linux)
- CLapacke-Linux (only for Linux)
- Swift Argument Parser
- Swift Numerics
Linux
This package depends on BLAS & LAPACK if running on Linux, more exactly, Ubuntu.
These dependencies are reflected in Package.swift
with:
- CBLAS-Linux, which in turn expects to find:
/usr/include/x86_64-linux-gnu/cblas-netlib.h
- CLapacke-Linux, which in turn expects to find:
/usr/include/lapacke.h
So, after installing BLAS & LAPACK (in case they are not already there):
sudo apt-get install libblas-dev liblapacke-dev
Check cblas-netlib.h
& lapacke.h
are in the expected locations.


Used to open a Constellation graph file. The standard menu for opening Constellation files is: File → Open
This command presents a dialog for selecting a file. Once the dialog is dismissed, the file is read and the contents displayed in a new graph window.
Constellation graph files are identified by the file suffix .star.
Constellation will not allow the user to open a graph file that is already open.
Note: The user may also open a Constellation file by dragging the file over the Constellation interface.

Fluff it up a little and hypnotize it. Those great big fluffy clouds. Isn't that fantastic that you can create an almighty tree that fast? I'll go over the colors one more time that we use: Titanium white, Thalo green, Prussian blue, Van Dyke brown, Alizarin crimson, Sap green, Cad yellow, and Permanent red.
Do an almighty painting with us. In your world you have total and absolute power. We have all at one time or another mixed some mud. There's not a thing in the world wrong with washing your brush.  That you can make these decisions. That you can create the world that you want.
As trees get older they lose their chlorophyll. I started painting as a hobby when I was little. I didn't know I had any talent. I believe talent is just a pursued interest. Anybody can do what I do. The little tiny Tim easels will let you down.
Son of a gun. Even the worst thing we can do here is good. A little happy sunlight shining through there. Isn't that fantastic? You can just push a little tree out of your brush like that.
Do an almighty painting with us. In your world you have total and absolute power. We have all at one time or another mixed some mud. There's not a thing in the world wrong with washing your brush.  That you can make these decisions. That you can create the world that you want.
A thin paint will stick to a thick paint.  So often we avoid running water, and running water is a lot of fun.

In section \ref{sec:eceval}, we will show how to implement a JavaScript evaluator as a register machine. In order to simplify the discussion, we will assume that our register machines can be equipped with a list-structured memory, in which the basic operations for manipulating list-structured data are primitive. Postulating the existence of such a memory is a useful abstraction when one is focusing on the mechanisms of control in a JavaScript interpreter, but this does not reflect a realistic view of the actual primitive data operations of contemporary computers. To obtain a more complete picture of how a JavaScript system operates, we must investigate how list structure can be represented in a way that is compatible with conventional computer memories.
There are two considerations in implementing list structure. The
first is purely an issue of representation: how to represent the
box-and-pointer
structure of JavaScript pairs, using only the storage
and addressing capabilities of typical computer memories. The second
issue concerns the management of memory as a computation proceeds.
The operation of a JavaScript system depends crucially on the ability to
continually create new data objects. These include objects that are
explicitly created by the JavaScript
functions
being interpreted as well
as structures created by the interpreter itself, such as environments
and argument lists. Although the constant creation of new data
objects would pose no problem on a computer with an infinite amount of
rapidly addressable memory, computer memories are available only in
finite sizes (more's the pity). JavaScript systems
thus provide an
automatic storage allocation facility to
support the illusion of an infinite memory. When a data object is no
longer needed, the memory allocated to it is automatically recycled
and used to construct new data objects. There are various
techniques for providing such automatic storage allocation. The
method we shall discuss in this section is called garbage
collection.


ArchNadeom, Keeper Of Records.
Stardate #262.
It was a touch on eternity.
A pause in the flow of time. A stillness of mind. When a quiet settles in. The senses becoming focused and acute.
When the little things that did not matter before, suddenly take on a precendence. Colors become brighter. Sound more crisp. Simple words take on a depth of meaning they do not otherwise possess.
WarWolff could see the light of the nearby moon. Pouring through the observation window. Touching the ozone in the air and streaming it into rays.
He could smell the metallic tang of the hull. Taste the adrenaline on his tongue. Feel the coarse fur of his cloak against his cheek.
He sensed something else too. Something not of this place. He felt their hush in the room. A presence just beyond his perception.
He could not see them, but he knew they were there. As they were always there. At every decisive moment. Nudging. Lifting him back up. Lending their strength.
The ancestors of Wolfpack.
WarWolff closed his eyes and gave them a silent nod.
“Protect my fleet. I have lead them as best I knew how.
They fight for the honor of the pack. They would honor you still, though they do not know you. As they have honored me.
“They are good wolves. Grant them your strength. See them through this day.”
WarWolff lifted his head and looked out. His gaze falling on the enemy armada before him. Victrix Mortalis.

“Engines to 50% power.”
The fleet responded to WarWolff’s command as if they were part of his ship. Holding formation. Keeping pace with their Lord Commander as if they were marching drill.
Wolfpack moved as one towards the enemy.
“Engines to 60% power.”
There is no drag in space. No airpockets or turbulence. No resistance to slow acceleration. To set a constant speed in space, you would simply fire the engines once and then turn them off.
To leave the engines running at a constant power does not maintain a constant speed. It continues the acceleration. Propelling the ship onward, faster and faster, as it hurtles madly at wildly increasing speeds.
There are limits to speed even in space, but they are measured in the astronomical.
“Engines to 70% power.”
WarWolff could feel the ship vibrating beneath him. A humming noise started in the beams and was slowly beginning to echo in the hull.
The images on the displays began to blur. The crew strapped themselves in. Fastening their wrists to the terminals to ensure they still pressed the right keys despite the vibrations.
“Engines to 80% power.
“ArchNadeom, break off formation and halt your advance. Engage the enemy when they come in range. Maintain a tactical retreat.”
Orders to an officer were different than those to a capitan. Officers were promoted based on their initiative, ingenuity, and ability to coordinate a squadron of ships.
WarWolff would not be directing this battle from afar. He would be part of the battle. As such, he would only be able to oversee the operations of the fleet to a limited degree.
He would depend on his officers to think independently. To be there. To respond. To act. To make the quick on-the-spot decisions that would be necessary to carry Wolfpack to victory.
As such, the orders for an officer had to be in terms of strategy and generalization. Allowing ample room for them to command their squadrons and respond to immediate threats as best they saw fit, while still carrying out their orders.
“Engines to 90% power.”
_sharky_ slowly began to pull ahead of the fleet.
The massive battering ram on the nose of _sharky_’s ship was better suited to close combat. Pulling ahead, he would engage the enemy at the same time as the long-range fire of the rest of Wolfpack.
WarWolff understood. He was as eagar as his captains to cut his teeth on the enemy. The captains knew their own ships better than he.
He would not countermand them. He had entrusted them with that authority. To countermand them would be to discredit himself in a misplacement of trust.
_sharky_ would draw the enemy’s first fire, but that battering ram would serve as much a shield for _sharky_ as it would a ram.
Godspeed _sharky_.
“Engines to 100% power.”
The entire ship was rattling. WarWolff grabbed a hold of the frame surrounding the observation window and began digging his fingers into the metal.
“Gun crew, load the 64 inch shells into the cannons. Fire on my command.”
Targeting would be choppy, but with the enemy fleet pressed so tightly together he was sure he would hit something.
The enemy ship Runningman swelled into range. Its black hull growing larger and larger as they drew closer. Filling most of the crosshairs.
“Fire!!”
The twin cannons Krupp and Big Bertha barked powerfully. Belching out two massive shells.
Big Bertha missed, but Krupp hit the side reactor.
With the velocity of the projectile added to the already incredible speed of WarWolff’s ship, the shell dimpled into Runningman’s shield and then popped through.
It mushroomed against the hull, doubling in size. Buckling the frame inward and then tearing off the whole rear starboard side of the ship.
_sharky_’s attack was not as successful.
He depended on surprise and hitting the enemy broadside, where he would have a much larger target and need to only compensate for minor adjustments in the enemy’s tilt or speed.
But facing the enemy head-on, the slightest change in direction for either ship could result in him missing completely.
At the last minute, the enemy veered to the right. Just before impact. _sharky_’s battering ram scraped along the side of the enemy ship. Shaving off the enemy’s port-side guns like barnacles under a knife.
Because Victrix Mortalis had arranged their fleet in such tight formations, they did not leave each other much room to maneuver.
When the ship veered starboard, he collided into another Victrix Mortalis ship. Jostling again the ships next to them. The rank of ships behind them barrelling on top of them in turn. Side into Side. Above and below.
It became a roadblock of broken ships.
CyberWocky had been following close behind _sharky_, riding right on his tail. When the enemy fleet crashed into each other and piled up in front of him, he smashed into the mass of hulls at full-speed.
Without the extra front armor of _sharky_’s battering ram though, CyberWocky’s ship crumpled like a can under a sledgehammer.
“Engines at full reverse! Crew, brace for impact!!”
WarWolff’s ship slid to a halt only a stone’s throw away from the enemy fleet. He was close enough to see the enemy crew flung around inside and the smashed systems through their windows.
A massive explosion rocked WarWolff’s ship from the port side.
“Sir, our port cannon has been hit. Enemy fire coming from our left flank.”
A mighty behemoth of a ship, flying under the name Brook-Lyn, had wheeled her assault onto WarWolff. The wall formation of Victrix Mortalis was slowly pivoting on its center and closing on Wolfpack’s flanks.
“Gun crew, focus your cannons on that pile-up of ships. Clear us an opening.
“xEEVEEx, enemy ships are breaking through our left flank. Hold your position until we can punch through that roadblock.”
.....
WarWolff’s ship was wracked by another heavy barrage of enemy fire from port-side.
“xEEVEEx, respond. Hold that flank!”
“Commander, SCVsUnion reporting. Lieutenant xEEVEEx split formation and flew off on his own. Voxar and I are fending them off as best we can, but we can’t hold much longer.”
xEEVEEx abandoned his post? In the middle of battle?
“Sir, our port cannon is destroyed. Our shields can’t withstand that much firepower. The hull is taking damage.”
Krupp was down. WarWolff would have to save any thought on xEEVEEx until later.
“Retarget all weapons on the enemy ship Brook-Lyn. Aim for the missle bays. Roborob, Invader and Guan Yu, board the enemy ship. Take down the reactors and slow her rate of fire.”
“Sumara, come in. Redeploy top squadron under Deathlord291 and assume command of left flank. Take Ivydocious with you. Reinforce SCVsUnion and Voxar before our flank collapses.”
“Aye aye, Commander!”
WarWolff looked out the starboard-side.
Machiel fought like one possessed. He was engaging three different enemy ships at once.
A strange green energy was coiling around the beams from Machiel’s lasers. Two of the enemy ships had lit up oddly with green fire that was leaping into space.
WarWolff didn’t know how long Machiel could sustain that power, but the enemy wasn’t pressing their attack.
Not far from Machiel, MizzBlaze sat eerily quiet.
There were no visible signs of weapon scoring on the outside of her hull, but her power was clearly dead. No running lights. No engine impulse. Nothing over the radio. She sat stock-still in space.
Librakron kept his distance. He looked as wary of Machiel as the enemy was.
“Seq and Hyten, take your squadron and form up on our rear.
“ArchNadeom, rejoin the fleet. Extend in a line beyond the rear formation. Do not let that wall close behind us or we are done for!”
“You have our word, Commander.”
Victrix Mortalis closed around them like a noose. Enemy ships pounding them from all sides.
_sharky_’s ship tilted upward at an awkward angle. Explosions rupturing along his side.
A torpedo slipped past Sumara’s shield. Killing her engine and stopping her ship in its tracks.
Two well-placed shots took out Machiel’s forward and aft lasers.
WarWolff looked on helpless. What had he done? His packmates were dying.
“a-Woooooooo!!”
It was a sound like sunlight through the clouds.
xEEVEEx flew out of the nebula with reinforcements on his wings. The powerful officers and ships of the former S.Q.U.I.D. WarFleet!
Their mighty pearlescent hulls no less diminished by their disbandment.

And something else too. The apparitions of wolves. Wolves howling on the flanks of xEEVEEx and the S.Q.U.I.D. warships.
Wolfpack’s ancestors had accepted them. They were S.Q.U.I.D. no more. From this battle to every battle thenceforth, every pack oath, every pack call, they would be wolves.
They tore into the backs of Victrix Mortalis like a hellstorm. Ships disintegrated whole under the awesome volley of their combined firepower.
Brook-Lyn disengaged from WarWolff to turn and meet the new threat. He took advantage of her distraction to fire a devastating shell from his remaining cannon Big Bertha into her reactor.
It triggered a chain-reaction of explosions across the other reactors. Destroying her ship.
xEEVEEx and his new wolf squadron fanned out around the edges. WarWolff rallied his remaining ships. Together, they destroyed the enemy commander Kirkbane before he could mount a defensive.
The enemy fleet routed. Victrix Mortalis lost its hold of power.
Wolfpack stood in its place.
WarWolff beamed proudly. A cheer erupted from his ranks. There would be celebration in the coming days.

Converting from Clawpack 4.6 to 5.0¶
(If you are converting code from Clawpack 4.3, see Converting from Clawpack 4.3 to 4.6.)
Many input parameters have been renamed and some new options have been added in Clawpack 5.0. See Changes to input parameters in setrun.py from 4.x to 5.0.
Python conversion tool¶
A first pass at the conversion of setrun.py, setplot.py and the Makefile can often be achieved by typing:
$ python $CLAW/clawutil/src/python/clawutil/conversion/convert46to50.py
in your application directory. You should then inspect the files generated and fix any broken links, etc.
The original versions of various files will have _4.x appended to the file name for reference. When conversion is complete, these files can be deleted.
Notes:
This does not yet work for all variants of the code.
Old AMRClaw codes are often in a subdirectory amr of an application directory, and the directory above may contain Fortran files or other files used by the AMR code. Typically you will want to combine these in one directory.
The Makefile is currently not converted properly – a generic Makefile is added to the directory but must be customized to point to any local Fortran codes, for example. In particular, make sure the Makefile points to the correct Riemann solver(s), either a local file or a library routine from the $CLAW/riemann/src directory.
The indices in q and aux arrays were permuted in Clawpack 5.0 relative to early versions, e.g. the m`th component of `q in grid cell (i,j) is now q(m,i,j) rather than q(i,j,m). The conversion script attempts to do this reordering if it sees a pattern of a suitable form, but you should carefully check your own local routines such as qinit or setaux to make sure this has been done properly.
Calling sequences of several routines have also been changed and will need to be adjusted by hand for any Fortran routines in your application directory. See User files required for the Fortran code for calling sequences of the routines that most frequently are provided by users. If you specify your own Riemann solver, see also Riemann solvers, and if you have custom boundary conditions, see Boundary conditions.
Note in particular that parameter maxmx (and maxmy, maxmz in more dimensions) is no longer in the calling sequence. In earlier versions of Clawpack this indicated the declared dimension of the q and aux arrays. It is now assumed the arrays are dimensioned properly since dynamic memory allocation is generally used at run time based on mx (resp. my, mz). You should remove these from the calling sequence and also modify the declaration of input parameters to use mx in place of maxmx, etc.
The classic code no longer requires a driver routine driver.f. In earlier versions of Clawpack this was used to declare the q and aux arrays to be sufficiently large for the size of the problem to be solved. (And specifying a larger value for mx led to a run-time error.) In Clawpack-5, a library routine driver.f90 is provided that calls the Clawpack routines, which now use dynamic memory allocation to allocate the required arrays at run time.

Royal Family's Instagram shares archive footage of the Queen's first televised Christmas speech in 1957 as fans marvel over 'how young' she looked
by Jessica Rach For Mailonline- Royal Family shared a throwback to the Queen's first televised speech in 1957
- Monarch, 93, first TV Christmas broadcast in 1957 from Buckingham Palace
- Many Royal fans remarked on how the Queen, then 31, looked 'like so young'
The Royal Family's Instagram account has shared a throwback to the Queen's first televised speech in 1957.
The monarch, now 93, was given the daunting task of delivering the first Christmas speech in 1952 aged 26, just months after the death of her father, King George VI.
And five years later, at 31, Queen Elizabeth gave her first televised Christmas speech from Buckingham Palace, calling it a landmark day' and giving a nod to her grandfather George V for starting the festive tradition on the radio.
This week the Queen's Instagram shared a throwback to the black and white speech, with fans commenting on how young she looked.
Dressed in a glitzy evening gown and the three-string pearl necklace gifted to her by her father King George when she turned 21 - a piece the monarch still wears - the Queen can be seen sitting by the piano, alongside a framed picture of Prince Charles and Princess Anne.
The Queen says: 'Twenty-five years ago, my grandfather broadcast the first of these messages.
'Today is another landmark, because television has made it possible for many of you to see me in your homes on Christmas Day.'
The caption reads: '1957 saw The Queen’s first televised Christmas message, broadcast live from the Long Library at Sandringham, Norfolk.
'The Queen’s grandfather, King George V broadcast the first Christmas message in 1932.
'The text for King George’s speech was written by poet and writer Rudyard Kipling and included the words, “I speak now from my home and from my heart to you all.”'
Gushing about the Queen, one follower noted: 'She was so young! She sound like a baby'.
'So incredibly regal,' while one said: And what a true privilege it must have been to be able to see and hear Her Majesty for the first time!
In 1952, dressed in a classic suit, the Queen took her seat behind a desk at Sandringham, Norfolk, where equipment had been set up to record her first Christmas message for radio.
In her message, she paid tribute to her late father, and asked people to remember her at the time of her Coronation the following June.
She also thanked the public for their support in the 10 months since her ascension to the throne.

Dear, Friend. My proposal to you will be very surprising, as we have not had any Personal contact before. However, I sincerely seek your confidence in this transaction,which I propose to you as a person of transparency,honesty and high caliber. Let me first start by introducing myself properly to you. My name is Ron Sinclear, i was the Personal Assistance to the (Haitian) President . I apologize if I have infringed on your privacy. It may interest you to know that the former president of (Haiti) has been fighting serious war for United Democracy for quite some years now, which has been backed (all along) by some foreign powerful countries. Not quite long ago, the American government ordered (President, Jean Bertrand Aristed) to leave (Haiti) or be forced out of power by a Rabel force.Knowing fully well the capabilities of America and other powerful members of the United Nations, (President Aristed) decided,and left the seat of power into exile in South Africa country to seek asylum. now a new government is in place . In the light of all these sad happenings, there was this deposit he made with a Security Company in Europe in year May 2001 ,this took place while he was still in power as the president of Haiti, through my aid, his Personal Assistant, (Ron Sinclear) and some loyalist, he suceeded to secretely move the sum of ($9.5M USD) (NINE MILLION,FIVE HUNDERED THOUSAND, UNITED STATES DOLLARS] to a private security company vault in Europe. Now, we need your services as a highly reliable foreigner to receive the funds into your bank account for the future survival of my family because he (Aristed) cannot presently operate any foreign bank account in his name. These funds (US$9.5m USD.) arose from various money i received from the sales of diamonds deals, i had with ( President Charles Taylor) of Liberia, which are abound in great quantity around the coastal areas of liberia. I have decided that if you are able assist us,you shall be compensated with 25% commission of the funds, 5% of this money shall be set aside to take care of any local or foreign expenses that might be incurred along the line. My family will have the remaining 75% of the funds. It might also interest you to note that all security arrangements regarding this transaction has been put in place, therefore,you have nothing whatsoever to fear or worry about, as every arrangement will be co-handled by you and my former Personal Assistant (Ron Sinclear) who is now presentely in Europe The Netherlands for possible conclusion of this arrangement. Most part of this share (70%) for my family will also be invested in a lucrative business courtesy of your full advice, assistance and connections because that is the most importat part of this transaction. As you indicate interest to assist my family,please kindly send to us your telephone/fax numbers for further discussion and clarification.I will be expecting to receive your urgent response for us to proceed to more details on .this pending transaction. God bless you as you respond promptly via my private Email<EMAIL_ADDRESS>Best regards, Ron Sinclear. ronsinclear@netscape.net

Jellyfish
Jellyfish or jellies are the major non-polyp form of individuals of the phylum Cnidaria. They are typified as free-swimming marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles. The bell can pulsate for locomotion, while stinging tentacles can be used to capture prey. Jellyfish are found in every ocean, from the surface to the deep sea. A few jellyfish inhabit freshwater. Large, often colorful, jellyfish are common in coastal zones worldwide. Jellyfish have roamed the seas for at least 500 million years, and possibly 700 million years or more, making them the oldest multi-organ animal.
Clownfish
Clownfish or anemonefish are fishes from the subfamily Amphiprioninae in the family Pomacentridae. Thirty species are recognized, one in the genus Premnas, while the remaining are in the genus Amphiprion. In the wild they all form symbiotic mutualisms with sea anemones. Depending on species, Clownfish are overall yellow, orange, or a reddish or blackish color, and many show white bars or patches. The largest can reach a length of 18 centimetres (7.1 in), while the smallest barely can reach 10 centimetres (3.9 in). Clownfish are native to warmer waters of the Indian and Pacific oceans, including the Great Barrier Reef and the Red Sea.

This potato battery is a great activity to discuss the transfer of energy, from chemical to electrical energy. It takes about 15 to 20 minutes to complete from start to finish.
Two potatoes
Knife
Two copper wires
Two pennies
Two galvanized nails
Multimeter with one black wire probe and one red wire probe
Cut out a penny-sized hole inside of a raw potato.
Strip one end of a copper wire.
Tie a copper wire around a penny, making sure the stripped end is touching the copper. You should wrap the wire around the penny a few times.
Place the penny and copper wire unit in the hole of your potato.
Pierce the potato with a galvanized nail, in the opposite side of the potato as the penny.
Do the same thing with another potato, penny, copper wire, and galvanized nail.
Place the two potatoes side by side.
Wrap the copper wire from one potato around the galvanized nail of the other potato.
So now you've made your potato battery, but what should you do with it? There are a variety of things you can do to see if your battery works and how it might be used.
Use a Multimeter - A multimeter measures voltage - so you can measure voltage by touching the multimeter's probes to the nail or penny.
 You can use LED lights, a light bulb, a simple clock, or anything else small that requires a battery. Keep in mind a potato battery isn't strong enough to power anything large. This is easiest to do if you use alligator clips to help connect your battery to the battery terminal of a small device.
There are a few variations you can try with this experiment. All of them are appropriate for any age. However, small children will require adult help.
Add more potatoes (with pennies and galvanized nails in them) to increase your voltage, by attaching the potatoes to each other with copper wires (see video).
Try boiling or cooking the potato first to see if this increases the output or voltage.
Try the experiment with a lemon or an orange.
The reason potato batteries work is because chemical reactions are taking place, and changing chemical energy into electric energy. Teach Engineering notes that potatoes create an electrolyte solution. This means they provide electrons with a place to move to copper and zinc (and back to copper) to complete circuits. The potato itself acts as a buffer between the copper and zinc during electron transfers.
The potato battery experiment provides an excellent way for kids (and adults) to learn more about science. Now that you've made a potato battery, you know more about how a circuit and electricity works.
Learn how to make a wave bottle using oil, water, and a secret ingredient that makes the whole thing fizz, bubble, and erupt.
Fill the bottle three-quarters full with vegetable oil.
Fill the rest of the bottle with water (almost to the top but not overflowing).
Add about ten drops of food coloring. Be sure to make the water fairly dark in color. Notice that the food coloring only colors the water and not the oil.
Divide the Alka-Seltzer tablet into four pieces.
Drop one of the tiny pieces of Alka-Seltzer into the oil and water mixture. Watch what happens. When the bubbling stops, add another chunk of Alka-Seltzer.
When you have used up all of the Alka-Seltzer and the bubbling has completely stopped, screw on the soda bottle cap. Tip the bottle back and forth and watch the wave appear. The tiny droplets of liquid join together to make one big wavelike blob.
First of all, you confirmed what you already know—oil and water do not mix. Even if you try to shake up the bottle, the oil breaks up into small little drops, but it doesn’t mix with the water. Why is it that oil and water are such opposites?
Oil and water don’t mix because of how their molecules are constructed. Water is what is known as a polar molecule. A water molecule is shaped like a V, with an oxygen atom at the bottom point of the V and a hydrogen atom on each of the two top ends. However, there is unequal sharing of electrons between the hydrogen and oxygen atoms. This means that the bottom of the molecule has a negative electrical charge, while the top carries a positive charge.
Vegetable oil, on the other hand, is a nonpolar molecule made of long chains of hydrocarbons—strings of carbon atoms bonded to hydrogen atoms. Unlike the water molecule, there is equal sharing of electrons between the carbon and hydrogen atoms. This means that the electrical charges of the atoms are not separated, so the molecules don’t have opposite positive and negative ends.
If you were to think of molecules like groups of people, the polar molecules hang out with other polar molecules, and the nonpolar molecules with other nonpolar molecules. This brings us back to the reason why oil and water don’t mix. Water is a polar molecule, and it just doesn’t hang out with nonpolar molecules like oil. Scientists say that oil and water are immiscible.
The adage “like dissolves like” will help you remember what will mix with what. Salt and water mix because both molecules are polar—like dissolves like. It’s also easy to mix vegetable oil and olive oil, or motor oil and peanut oil . . . but that’s gross.
You also noticed that food coloring only mixes with water . . . and now you know why. Food coloring is a polar molecule because it dissolves in water. In other words, food coloring and water are miscible. Vegetable oil is not affected by the food coloring because they are polar opposites.
Here’s the surprising part . . . the Alka-Seltzer tablet reacts with the water to make tiny bubbles of carbon dioxide. These bubbles attach themselves to the blobs of colored water and cause them to float to the surface. When the bubbles pop, the color blobs sink back to the bottom of the bottle, and the whole thing starts over until the Alka-Seltzer is used up. When the chemical reaction between the Alka-Seltzer and water is over and the bubbling stops, you’re left with a cool looking wave bottle that will sit proudly on your desk.


Welcome to pyDNTNK’s documentation!¶
pyDNTNK is a software package for applying non-negative Hierarchical Tensor decompositions such as Tensor train and Hierarchical Tucker decompositons in a distributed fashion to large datasets. It is built on top of pyDNMFk. Tensor train (TT) and Hierarchical Tucker(HT) are state-of-the-art tensor network introduced for factorization of high-dimensional tensors. These methods transform the initial high-dimensional tensor in a network of low dimensional tensors that requires only a linear storage. Many real-world data,such as, density, temperature, population, probability, etc., are non-negative and for an easy interpretation, the algorithms preserving non-negativity are preferred. Here, we introduce the distributed non-negative Hierarchical tensor decomposition tools and demonstrate their scalability and the compression on synthetic and real world big datasets.
See pyDNTNK code here.

Hello :-)
This is the user guidance for the visulation for redundant framework structure, where the methodology is explained in theory section.
The control surface alters the magnitude of external force, unit load in the 3rd graph and virtual force in the 4th graph.
The theory button directs you to the theory section.
The visulization parts compares deformation of the framework structure using different methods and also validates the principle of virtual work.
Enjoy!


Basics
Algorithms are a backbone of the field of Computer Science. Although, as a computer scientist, we may have learned all basic algorithms, it becomes difficult to keep track of it all. Hence, when I referred to Code Monk tutorials, I wanted to compile all the basic algorithms for easy reference, and here it is.
Algorithms based on bitwise operations
- Checking whether a given number is a power of 2 - If x is a power of 2, then x & (x-1) = 0. Complexity : O(1)
bool isPowerOfTwo(int x)
{
// x will check if x == 0 and !(x & (x - 1)) will check if x is a power of 2 or not
return (x && !(x & (x - 1)));
}
- Checking number of ones in a binary representation of a number. Complexity : O(k) where k is number of ones in a binary representation of a number.
int count_one (int n)
{
while( n )
{
n = n&(n-1);
count++;
}
return count;
}
-
Left-shifting a number by k times multiples it by 2k. And right-shifting divides it.
-
Check if the ith bit is set in the binary form of the given number. And the number with 2^i and if non-zero then bit is set.
bool check (int N)
{
if( N & (1 << i) )
return true;
else
return false;
}
- Generating all possible subsets of a set. Logic is to represent a presence of a number by 1 and absence by 0.
void possibleSubsets(char A[], int N)
{
for(int i = 0;i < (1 << N); ++i)
{
for(int j = 0;j < N;++j)
if(i & (1 << j))
cout << A[j] << ‘ ‘;
cout << endl;
}
}
- To find the largest power of 2 (most significant bit in binary form), which is less than or equal to the given number N. Logic is to change all bits of right side of MSB to 1. This will give a number which is (2*x - 1) where x is the required answer.
long largest_power(long N)
{
//Amazing logic to change all bits at right of MSB to 1
//changing all right side bits to 1.
N = N| (N>>1);
N = N| (N>>2);
N = N| (N>>4);
N = N| (N>>8);
//as now the number is 2 * x-1, where x is required answer, so adding 1 and dividing it by 2.
return (N+1)>>1;
}
-
x ^ ( x & (x-1))
: Returns the rightmost 1 in binary representation of x. -
x & (-x)
: Returns the rightmost 1 in binary representation of x -
x | (1 << n)
: Returns the number x with the nth bit set.
Sorting Techniques
- Bubble Sort
void bubble_sort( int A[ ], int n ) {
int temp;
for(int k = 0; k< n-1; k++) {
// (n-k-1) is for ignoring comparisons of elements which have already been compared in earlier iterations
for(int i = 0; i < n-k-1; i++) {
if(A[ i ] > A[ i+1] ) {
// here swapping of positions is being done.
temp = A[ i ];
A[ i ] = A[ i+1 ];
A[ i + 1] = temp;
}
}
}
}
- Selection Sort - Find minimum and start swapping from leftmost elements
void selection_sort(int A[], int n) {
// temporary variable to store the position of minimum element
int minimum;
// reduces the effective size of the array by one in each iteration.
for (int i = 0; i < n - 1; i++) {
// assuming the first element to be the minimum of the unsorted array .
minimum = i;
// gives the effective size of the unsorted array .
for (int j = i + 1; j < n; j++) {
if (A[j] < A[minimum]) { //finds the minimum element
minimum = j;
}
}
// putting minimum element on its proper position.
swap(A[minimum], A[i]);
}
}
- Insertion Sort - Maintain a sorted array and put a new element in the appropriate position in the sorted array
void insertion_sort(int A[], int n) {
for (int i = 0; i < n; i++) {
/*storing current element whose left side is checked for its
correct position .*/
int temp = A[i];
int j = i;
/* check whether the adjacent element in left side is greater or
less than the current element. */
while (j > 0 && temp < A[j - 1]) {
// moving the left side element to one position forward.
A[j] = A[j - 1];
j = j - 1;
}
// moving current element to its correct position.
A[j] = temp;
}
}
- Merge Sort - Quite useful due to its O(N*logN) runtime.
void merge(int A[], int start, int mid, int end) {
//stores the starting position of both parts in temporary variables.
int p = start, q = mid + 1;
int Arr[end - start + 1], k = 0;
for (int i = start; i <= end; i++) {
if (p > mid) //checks if first part comes to an end or not .
Arr[k++] = A[q++];
else if (q > end) //checks if second part comes to an end or not
Arr[k++] = A[p++];
else if (A[p] < A[q]) //checks which part has smaller element.
Arr[k++] = A[p++];
else
Arr[k++] = A[q++];
}
for (int p = 0; p < k; p++) {
/* Now the real array has elements in sorted manner including both
parts.*/
A[start++] = Arr[p];
}
}
void merge_sort(int A[], int start, int end) {
if (start < end) {
int mid = (start + end) / 2; // defines the current array in 2 parts .
merge_sort(A, start, mid); // sort the 1st part of array .
merge_sort(A, mid + 1, end); // sort the 2nd part of array.
// merge the both parts by comparing elements of both the parts.
merge(A, start, mid, end);
}
}
- Quick Sort - If randomized pivot is used, complexity varies between O(N^2) and O(N*logN)
int partition(int A[], int start, int end) {
int i = start + 1;
int piv = A[start]; //make the first element as pivot element.
for (int j = start + 1; j <= end; j++) {
/*rearrange the array by putting elements which are less than pivot
on one side and which are greater that on other. */
if (A[j] < piv) {
swap(A[i], A[j]);
i += 1;
}
}
swap(A[start], A[i - 1]); //put the pivot element in its proper place.
return i - 1; //return the position of the pivot
}
void quick_sort ( int A[ ] ,int start , int end ) {
if( start < end ) {
//stores the position of pivot element
int piv_pos = partition (A,start , end ) ;
quick_sort (A,start , piv_pos -1); //sorts the left side of pivot.
quick_sort ( A,piv_pos +1 , end) ; //sorts the right side of pivot.
}
}
- Counting Sort - For each element a[i], increase count by 1 in aux[a[i]]. Complexity is O(N+K) where K is the maximum element in the input array.
void counting_sort(int A[], int Aux[], int sortedA[], int N) {
// First, find the maximum value in A[]
int K = 0;
for (int i = 0; i < N; i++) {
K = max(K, A[i]);
}
// Initialize the elements of Aux[] with 0
for (int i = 0; i <= K; i++) {
Aux[i] = 0;
}
// Store the frequencies of each distinct element of A[],
// by mapping its value as the index of Aux[] array
for (int i = 0; i < N; i++) {
Aux[A[i]]++;
}
int j = 0;
for (int i = 0; i <= K; i++) {
int tmp = Aux[i];
// Aux stores which element occurs how many times,
// Add i in sortedA[] according to the number of times i occured in A[]
while (tmp--) {
//cout << Aux[i] << endl;
sortedA[j] = i;
j++;
}
}
}
- Radix Sort - Modification of Counting Sort with focus on reducing complexity
void countsort(int arr[], int n, int place) {
int i, freq[range] = {
0
}; //range for integers is 10 as digits range from 0-9
int output[n];
for (i = 0; i < n; i++)
freq[(arr[i] / place) % range]++;
for (i = 1; i < range; i++)
freq[i] += freq[i - 1];
for (i = n - 1; i >= 0; i--) {
output[freq[(arr[i] / place) % range] - 1] = arr[i];
freq[(arr[i] / place) % range]--;
}
for (i = 0; i < n; i++)
arr[i] = output[i];
}
void radixsort(ll arr[], int n, int maxx) //maxx is the maximum element in the array
{
int mul = 1;
while (maxx) {
countsort(arr, n, mul);
mul *= 10;
maxx /= 10;
}
}
- Heap Sort -
max_heapify()
function must be first implemented. Complexity :max_heapify()
has complexity O(logN),build_maxheap()
has complexity O(N) and we runmax_heapify()
N−1 times in heap_sort function, therefore complexity ofheap_sort()
is O(NlogN).
void heap_sort(int Arr[])
{
int heap_size = N;
build_maxheap(Arr);
for (int i = N; i >= 2; i--) {
swap | (Arr[1], Arr[i]);
heap_size = heap_size - 1;
max_heapify(Arr, 1, heap_size);
}
}
- Bucket Sort - Mainly Useful when the input number are uniformly distributed over a range. Complexity O(n), if insertion complexity is O(1) {Possible using linked lists}.
void bucketSort(float arr[], int n)
{
// 1) Create n empty buckets
vector<float> b[n];
// 2) Put array elements in different buckets
for (int i=0; i<n; i++)
{
int bi = n*arr[i]; // Index in bucket
b[bi].push_back(arr[i]);
}
// 3) Sort individual buckets
for (int i=0; i<n; i++)
sort(b[i].begin(), b[i].end());
// 4) Concatenate all buckets into arr[]
int index = 0;
for (int i = 0; i < n; i++)
for (int j = 0; j < b[i].size(); j++)
arr[index++] = b[i][j];
}
int main()
{
float arr[] = {0.897, 0.565, 0.656, 0.1234, 0.665, 0.3434};
int n = sizeof(arr)/sizeof(arr[0]);
bucketSort(arr, n);
cout << "Sorted array is \n";
for (int i=0; i<n; i++)
cout << arr[i] << " ";
return 0;
}
Data Structures
- Stacks
#include < iostream >
using namespace std;
int top = -1; //Globally defining the value of top as the stack is empty
void push(int stack[], int x, int n) {
if (top == n - 1) //If the top position is the last of position of the stack, this means that the stack is full.
{
cout << "Stack is full.Overflow condition!";
} else {
top = top + 1; //Incrementing the top position
stack[top] = x; //Inserting an element on incremented position
}
}
bool isEmpty() {
if (top == -1) //Stack is empty
return true;
else
return false;
}

Hash Tables
- Choice of a Hash function is very important. It must be easy to compute, less collisions and must distribute output values uniformly.
- Separate Chaining (Open Hashing) means having a collision element linked to the first element, and such links grows with more collisions.
- Linear Probing/ Open Addressing/ Closed Hashing - using arrays to store values. Also quadratic probing can be used.
- Double hashing techniques can also be used..
- Mainly used to improve speed.

What is Gestalt?
The German word "gestalt" can be translated into meaning "whole" or "form." Originating in the 1920s, it is a form of psychology that looks at the human mind and behaviors as a whole. Founded by Max Wertheimer, Wolfgan Kohler and Kurt Koffka, gestalt includes a set of organizing principles known as Gestalt Laws.
