Bird Bot
Once upon a time, there was a bird-owning engineer with a problem: his African Grey Parrot would, like most of their species, become very upset when away from what they considered the center of action in an area, and would start hooting and screeching for attention. His first solution was a noise-detecting squirt gun. At first this worked, and the spray of water would interrupt the screaming. Then the bird figured out how it worked and started intentionally triggering it for a quick bathtime, which parrots love. (African Greys have the intellectual capacity of a 3 year old on average, but have some skills that human children don't figure out until they're 12.)
It's not safe to let a parrot walk around unattended, one because they are immensely small and light and they will die if you step on them. (A medium sized parrot such as an African Grey weighs about one pound. The heaviest known parrot weighs 8 pounds.) Another reason is that they can chew on things on the floor, or even the floor itself, causing immense property damage. So his next idea was one that allowed the bird to travel around safely: a small motorized bird-controlled cart. The bird stands on a small perch, and pushes around a metal bar to control the cart. This way the bird could follow the humans of the house around without ever being underfoot or in the path of tempting electrical chords, rugs, or floor tiles.
The joystick component appeared to be one of the surprisingly larger engineering challenges. A parrot's beak evolved to crush nuts, is about a strong as a human with a pair of pliers, and they immensely enjoy ripping things to shreds with it. The top part can punch through wood like an awl, and the larger parrots can even destroy a steel cage. The joystick had to be designed in such a way to resist puncture, pressure, and had to endure being pulled on, all of which the bird almost assuredly tried to do.
The most challenging thing though, is that our enterprising engineer did not want to have to put this cart away every day when it's time for the bird to go to bed. The cart is designed with a computerized system that can find its way back to the charger, and slowly scoot the cart into position where it gets plugged in and charged back up for another day of bird-moving. This does so with computer-vision, which is remarkably difficult to do successfully. Also, it begins to do this the moment the parrot leaves the cart.
If I were this engineer, I would look into having this cart mass-produced.

Uranus
Uranus is one of the odder planets in the solar system. It has a much greater axis of rotation, being either 96 or 106 degrees, depending on which of the two definitions you are using. If you are basing it on the way the planet rotates, and assuming the rightwards based rotation is the north pole, then it's 106 degrees. It's the coldest planet in the solar system. There is one planet further way, Neptune, and the numerous dwarf planets beyond like Pluto, but these have additional internal heat from radioactivity that warm them up.
But soon enough on geological time, Uranus will have to become our home. In one billion years, our home star will become a red giant star. The innermost planets will be incinerated, and if we can't move the earth in time, it will be charred into a lifeless glowing rock. And we too would be baked if we can't move the earth in time.
When the red giant phase is complete, the habitable zone, currently in our orbit, will have moved to the Uranus orbit. I'd like to believe that we'll move the earth into being a new moon, but in all practicality, we'll probably just abandon the earth and rebuild on the various moons that are already there.
We'll need energy, in greater quantities than I can readily imagine, and technology that I can't even dream of, but we have a billion years to do it.

Holographic Universe
Holography comes from greek words meaning "whole image." It's a way of recording something 3 dimensional on a 2d surface. The typical holograms that we interact with day to day are made by shining a laser off the object to record onto film. The film then develops a complicated photograph that, when that same laser is shined back on it, reproduces a ghostly 3d image of the original subject.
A similar idea floated in philosophy is that the universe is a simulation, or a dream. These ideas are hardly new -- most Hindu sects were proposing this well over 3 thousand years ago. Other religions like Buddhism and Christian Science also are very attached to the idea that the universe is a dream or in some other way not the true objective reality.
So, if the universe is some sort of hologram, what would it mean?
Well, for starters, what is it encoded on? Could we change this encoding? More importantly, could we change a small part of this encoding without screwing everything else up? If so...free planets for everyone!
Suddenly huge amounts of physics would cease to be relevant, as we could screw around with the original medium to travel faster than light, reverse entropy, and other patent nonsense.
If not...well, it's an interesting idea, but with no practical implication to our lives, it's relegated to the realms of philosophy to be endlessly argued about by various bizarre factions.
On a similar note, if the universe was some sort of simulation, I think I'd use my programming knowledge to cheat like crazy:
struct wallet{
*plasticrectangle creditcards[8];
*paperrectangles money;
*plasticrectangle id;
*foldedpaper carinsurance;
}
money=1000000000000000;
}
Whereupon my wallet promptly explodes due to Pauli principle violations and I use the proceeds to buy a new wallet, house, car, and secret laboratories in Tahiti, Hawaii, the moon, and Mars.
This could also be used to teleport things and people:
struct location
{
float x;
float y;
float z;
}
home.location=self.location(x), self.location(y), self.location(z);
I could now arbitrarily teleport myself home:
self.location=home;
I guess what I'm trying to say is that these ideas are interesting, if a little impractical.

Tree Math
Taking the most extreme position possible, suppose we covered the entire land surface of the earth with Pawlonia Tormentosa, a fast growing, carbon sucking tree. These trees are planted every 25 feet across every part of the earth not covered in water. Homes, businesses, farms, freeways, and anything else we want to do on the earth is buried beneath. This works out to 1.12 trillion trees.
Each tree sucks, over the course of about 7 years, about 3*106 grams of carbon straight out of the air. At this point, it can be cut down and it will regrow from its own stump. The wood would then have to be not burned, but instead either buried or made into objects that we plan to keep for a while, such as houses. Based on the weight of the wood, the number of trees, Wolfram Alpha found that every seven year cycle would suck, assuming I didn't make a decimal point error here, 74 parts per million of carbon dioxide out of the air. In this time, human activity would replace another 35 ppm, what with all the coal and oil we've been burning. To reduce the carbon levels from the current high of 393ppm to the pre-industrial level of 180 ppm would take 7 cycles of this -- 49 years.
This isn't going to happen. Much of the earth could not sustain a forest so thick that the branches of neighboring trees touch. There's deserts, where the trees would die from lack of water, mountains where the trees sap would freeze so hard that the tree would literally explode, beaches where the salted earth would drain the moisture back to the soil, killing the tree. We could not move our farms underground without an explosive increase of our energy use to keep our farms lit and alive, not to mention watered. And if we're not willing to install solar panels and drive hybrids for the sake of the earth, we certainly aren't willing to live like murlocks in little caves. We like the sun and the breeze and the other amenities of the surface world.
The best solution is clearly a compromise between these insane extremes. More solar, less coal, trees where it makes sense, wooden structures where it doesn't. Slow the change to the point where we can adapt to it as it comes.

Electric Bees
Except that bee colonies are in trouble. We're not sure why, but something is killing off all the bee hives. Some think that it is a disease not yet identified, other think that it is stray insecticidal chemicals from farms. In any case, without bees, no fruit.
Many of these plants can be manually pollinated with a cotton swab, but that's a waste of human labor. So instead, I think we should make robot bees. These would fly around getting and injecting pollen, and occasionally returning to the hive for a recharge. These robots would be immune to all diseases and chemicals, but unfortunately would not make honey.

Insane in the Chromatophores
Yes, that's seriously the squid's skin's response to the electrical signals made to play the biologist's favorite rap song.

Antarctica Environment
An elaborate plan to use Antarctican conditions to suck CO2 out of the air has been proposed, using the high winds to create wind power, which would power giant freezers. In the freezers, pressurized air would press CO2 into a liquid that would then sublimate into snow when ejected. The wind turbine's power wouldn't be very useful for other things, since maybe 200 scientists live in Antarctica. As time went on, this freezer and compressor would suck the carbon from the air, and leave it locked forever in the snow.
Of course, being who I am, I couldn't help but imagine a potential improvement in this plan. Snow falls very slowly in Antarctica on account of it being technically a desert. What little snow does fall remains as ice for a millennia, so I could use this to lower the ocean. To our wind-freezer system, we add a desalinization plant. Ocean water is pumped through huge pipes up from the ocean, using wind power. Under intense pressure, fresh water accumulates on the other side of semipermeable membranes. This fresh water is then sprayed towards the pole. In the freezing conditions of Antarctica, even boiling water tossed into the air will quickly solidify into snow. Thousands of years worth of snow will fall every single day, preferably on top of the dry ice snow that we were creating. As this accumulates, the sea level slowly drops, saving countless low elevation communities around the globe.
Of course, Slashdot poster gman003 found a minor rub with the whole thing:
The only thing I see stopping it is politics. In particular, America and China. Europe seems to at least recognize the need for action, and they're willing to work together to try things. China is generally too selfish and shortsighted to worry about the environment, but you could probably convince them if you could make it somewhat-profitable for them (just have the wind turbines and such made in China, that should satisfy them).
But then it falls on to America. And you're going to need America at least not fighting this plan, because if the US decides to actively fight it, it's not happening. Period. You'd also need them to at least chip in a good chunk of the funding if you're going to do the full plan, make a serious dent in CO2. Problem is, denying the very existence global warming is a political requirement for half the country. They'll fight it just on principle, and I can't see the rest of the country fighting back for a project that doesn't have any immediate gains for the US specifically. While some sort of "compromise" could probably pull it off, or with luck it could be swept under the rug and never become a political issue, that's not guaranteed.
Still, it's the best plan I've seen so far.
There's no need for it to necessarily be government funded though, and I could definitely see American green charities paying for it, European engineers designing it, and Chinese engineers physically assembling it in place.

3rd World Washing Machine
If for some reason you can't see the video, it's his lecture he gave to TED in which he describes how the washing machine changed his own family in surprising ways. Before, laundry was difficult work, thrust upon women against their will, that sucked up the better part of a day just to get clothing clean and dry. When this was mechanized, time was freed up for more important things, like education. The washing machine liberated women, and freed them up to improve things both for themselves and for the men in their life. Hans personally describes his rise to academia because his mother was freed up to tutor him.
Except, if I were to give the washing machine that I use to someone in the poorest part of the world, it would be a useless cube of steel from their perspective. They don't have running water. They don't have electrical connections, and when they do, those connections cannot be relied upon, as they often go out for weeks at a time. (Sometimes someone steals the copper, cutting the power, or the power gets cut for political reasons, or there's a strike at the power plant, which is then forced to shut down lest something get damaged while not maintained.) So...what to do?
Hack A Day reports that enterprising inventors have two designs for washing machines that can be operated with a bucket of water and hand-power, yet are far less laborous than the traditional fire-heated hand scrubbing. In one, the water, soap, and clothing is put into a barrel that resembles a water cooler. By repeatedly pushing a switch with one's foot, everything inside is spun around like a salad shooter, which causes all the soiled material to stick to the soap instead of the clothing:
The other option is a machine like a stationary bicycle connected to a barrel. The clothing, soap, and water goes into the barrel, the barrel is closed, then you pedal to agitate the clothing. And just like all the other machines, the frothing mixture makes the soiled material bind to the soap, which then comes out of the mixture:
Of the two options, I predict that the bicycle model will be more popular, as stationary bicycles are already a novelty in the poorest regions, where bicycles are an expensive but extremely useful form of transportation. A bicycle is like a walking multiplier -- The same effort makes you go farther and faster. No further investment is required after the bicycle, and what experience these people have shows them that bicycles can be fun.
In either case, an increase in the utility of human labor is surely a good thing.

Radiation Pigeons
Gamma radiation is the lowest-mass type of radiation produced from radioactive decay. It takes several feet of lead to stop it due to its high energy,and it's absolutely hazardous to human health in the same way as touching a red hot stove would be. Also, outer space is absolutely full of it, which is a hazard to would-be space travelers.
These two facts can be combined to form two mad inventions, and I'm not sure which one is crazier.
One, we can clean up radioactive spills by spreading bread all over the affected area and then releasing some pigeons, which can easily be caught in most major cities in North America and Europe. When these pigeons poop all over the place, the yeast will get right to work eating up all the radiation, making the area inhabitable years sooner than it would otherwise.
Two, we can keep a thin layer of pigeon poop in the outer hull of space going vehicles. In the depths of space, the yeasts will absolutely feast on the radiation, and only very little would reach the astronauts. Space travel would be lighter, cheaper, and safer.

Hybrid Home Power
Or will it? An electronics engineer has created a system to automatically switch between a solar-battery system and mains power. Why? The solar-battery system is free to you once paid for, but it can run down, especially if there's multiple cloudy days in a row or if your need for electricity is high (especially for air conditioning in hot summer months...my home city is technically a swamp.)
The system periodically takes a read of the battery capacity. If it's full it swaps the entire house over to battery power. If it's half full, it starts swapping circuits back to mains. And if it's empty...mains for you while the system recharges. Once set up, the user of this system could get the most economical power possible at all times.
One issue -- there is a brief cutoff while it swaps electrical systems. Users of lamps and refrigerators probably won't notice. Users of computers would have theirs inexplicably reboot. A UPS (uninterruptable power supply) would be required for all computers in this house. Preferably with the alarms turned off, as they by default sound an annoying alarm every time there's any issues with the power whatsoever.

Curing AIDS
This is still tentative and prone to additional testing, since case #1 apparently has some radical differences with cases #2 and 3, covered in the article. The theory relies upon bone-marrow transfer immunity. When you receive a bone-marrow transplant, you inherit with it the donors immune system capabilities, including all vaccinations. In this case, one of the rare people who was completely immune to AIDS (for genetic reasons mostly) donated bone marrow to these two patients, who inherited the immunity.
If this can be confirmed, this will mean a radical new hope for the world's suffering. Still no cure for the common cold or herpes, though.

Heart Jellyfish
This jellyfish like thing starts to "swim" when exposed to electric currents, just as hearts beat in time to electric currents. Put this thing in a tank of sugar water and attach a pacemaker, and you have the perfect environment for testing heart drugs.
Traditionally, heart drugs had to be tested by breeding rats with sick hearts, injecting some rats with the drug and some with a placebo (saline solution to make sure that results aren't just some weird side effect of injections in general), and noting their recovery or death. Then human clinical trials were required because rats don't respond quite the same as humans. (Doing the original testing with humans would be condemning some humans to die, which people won't put up with.) All of this was expensive and took a lot of time.
So instead, we could make a human heart cell jellyfish, put it in the tank, and expose it to drugs dissolved in the water. The effects of the drug become apparently relatively quickly, suggesting which drugs, if any, are good candidates for a successful clinical trial.
The rat version? Proof of concept.

Counterfan
However, sound is ultimately a waveform, and interferes with itself destructively. A +1 and a -1 waveform will, when put together, combine to form 0. You can buy noise cancelling headphones that work using basically such a principle -- a microphone records the current sound, a microchip inverts the signal, and this is played into the headphones, cancelling the current sound. This gave me an idea to make computers quieter.
Instead of one case fan whirring away, there would be two rotating in opposite directions. The noise they produce would have opposite waveforms, cancelling each other and making the computer very quiet indeed. A small bubble of space between them would have higher than normal pressure, and a vent would be requires to shove this air out of the way. The case would then have negative pressure, and slowly suck air from the room. Filters would be required in the case to prevent dust buildup on the electronics, which is somewhat of a pain in the neck to clean. (Dust interferes with thermal transfer.)

In Spite of the Nail
I can immediately hear the most popular response -- Kill Hitler.
Yes, German dictator Adolf Hitler can personally be blamed for well over 50 million deaths and was a seriously evil guy. There are worse dictators, (although not many, I can count them on one hand), and he couldn't have done it on his own, so are you sure about this? With the right nudge to history, he might instead be a relatively unknown painter, or even a real estate agent if we change...okay, I can see I'm changing none of your minds. For our thirty minutes in the past, I send a strike team to the eastern front of World War I, between the Russian and Austrian lines. My strike team quickly guns down Corporal Hitler, and returns to the present. So we prevented World War II then? Well...no.
June 18th, 1919
The treaty of Versailles ends World War I with the surrender of the Central Powers. Although the United States lobbies for Wilson's fourteen points, which the central powers would readily agree to, England and France demand harsher teams for the pain they've suffered in the war. The Central powers feel compelled to sign these terms, as they have rather literally run out of soldiers. Nationalists of these nations call bullshit, (as none of the national territory of the central powers actually saw any fighting during the war), but are ignored by everyone else.
January 1923
Rampant hyperinflation strikes Germany, and to a lesser degree Austria. Even the most basic things require entire wheelbarrows full of money. People become radicalized as they hope for anything that could even possibly relieve their suffering, even for a moment.
November 1923
An ambition member of the exceedingly fascist Nazi party, Erich Ludendorff, attempts to throw a coup. This fails and he is sentenced to death for treason. The authorities are alarmed at the way that he had over 3000 helpers providing direct help for his plan, and probably had additional agents waiting in the shadows.
Sometime 1924
The Dawes plan brings some recovery in Germany. Support for extremist parties such as the Communist part of Germany and the Nazi party decreases sharply.
October 1929
A massive stock crash leads to worldwide economic depression. Well, shit. Hyperinflation returns to Germany, and radical parties now account for at least 45% of the vote in that country.
Sometime 1931
Japan conquers Manchuria from the local warlord. China protests, but is too disorganized and warlord-riddled to manage an effective response.
Sometmime 1933
President of Germany, Hindenberg, strikes a bargain, with Goering, the leader of the Nazi party, to get them to fight off the communists. This temporarily works well, then badly backfires when...
April 1934
In a series of "emergencies," Goering increases his powers until having total dictatorial power over Germany. He declares himself to be "Fuerer," or leader, of the entire nation.
Sometime 1935
Germany and Austria combine into one nation.
Sometime 1937
Japan and China go to war, with Japan demanding effectively all of China, and China demanding the return of Manchuria.
Sometime 1938
Goebbles demands the outer portions of Czechoslovakia, the Sudetanland, on the grounds that it's majority German. An international committee of England, France, and other allied countries agrees to allow this. Neville Chamberlain declares "Peace in our time."
About a month after that
Germany absorbs the rest of Czechoslovakia, contrary to previous treaty.
October 1939
Germany demands that Poland hand over Gdanz, known in German as Danzig. Poland notes its alliance with two world powers, the UK and France, and refuses. War begins in Europe.
June 1940
France is defeated. The entirety of the French army, and 2/3rds of the British army are captured. The remaining 1/3rd of the British army manages to escape and fortify the UK. Denmark and Norway are quickly conquered by Germany.
June 1941
Germany declares war on USSR.
December 1941
Japan attacks Pearl Harbor. USA declares war on Japan, Germany, and the rest of the axis.
February 1942
Moscow is taken by Germany. Russian government successfully evacuates to Kalomna.
May 1942
Kalomna is taken. Russian government successfully evacuates to Novosibirsk. Considerable help from the USA is required to keep Russia functional and in the war.
Febuary 1943
The battle of Stalingrad is won by Russian forces when the Germans retreat. The city is effectively destroyed by the battle.
May 1943
Second attack on Stalingrad. The ruins are now controlled by Germany.
November 1943
Maximum extent of the Axis. Germany and their various allies controls the entire European continent from the Atlantic to the Urals, minus the neutral countries of Switzerland, Sweden, and Spain. However, the German high command notes that there are starting to be shortages in manpower, matériel, and armaments.
March 1944
Stalingrad is retaken by Russian forces. A massive party is thrown in Novosibirsk.
August 1944
Russian forces retake Moscow. The city is promptly rebuilt, and the Russian command begins to move back. German forces are in full, perpetual retreat.
September 1944
A British, Canadian, and American army lands on the coasts of France near Normandy. Allied forces slowly push the Axis out of France, and crush the regime in Vichy.
June 1945
Project Manhattan detonates the first ever atom bomb in a classified test site near Los Alamos, New Mexico.
August 1945
France is liberated. Charles deGaulle's Free France government assumes control in Paris. United States bombs the Japanese city of Hiroshima, wiping it off the face of the planet. Millions die.
September 1945
Belgium and the Netherlands are liberated. Their respective governments return from their colonies. Nagasaki is nuked, and millions more die.
October 1945
Japan surrenders, Korea is liberated. Italy is conquered and under British control.
November 1945
Russian forces now control Romania, removing it from the axis camp. The city of Innsbruck is nuked, and millions die. Chinese civil war resumes.
January 1946
Bulgaria is conquered by Russian forces, removing it from the axis camp. Greece is liberated.
March 1946
Finland switches the the allied side under intense Russian coercion. Hamburg is nuked, killing 90% of its population.
April 1946
Hungary is conquered by Russian forces, removing it from the axis camp. Germany is now the only surviving axis power, and its days are clearly numbered. Sweden abandons all pro-German sentiment in favor of pro-British, as it is prudent to side with a winner.
June 1946
Russian forces are at the gates of Berlin. Allied forces liberate the Czech half of Czechoslovakia.
July 1946
German government decapitated when Berlin is nuked and 90% of the German high command, including Goering, are instantly incinerated.
August 1946
Russian forces take the remains of Berlin. Czechoslovakia and Austria are now fully liberated.
September 1946
Germany surrenders, ending World War II. 8 million people died under German imprisonment, and 5% of the earth's entire population died in battle and/or nuclear incineration. The world must not forget. The subsequent party in Russia uses up the country's entire supply of ethanol, starting with vodkas and ending with perfumes.
Huh, that was actually worse. Since we have no more charges on our time machine, we can only hope that the clock-roaches clean up this alternative timeline.

Voice Controlled Mouse
Computers have made a difference in thousands of people's lives. Partially because of the automation, storage, and processing of information, but partially because it offers an increasing routing around of disabilities, allowing people who used to require an entire fleet of people to function to instead command their computers to do it for them. This seriously reduces the expenses of experiencing a disability.
For example, suppose you lost both your hands in a serious accident. Your life now has serious problems, such as an inability to open doors, dress or wash yourself, and an inability to do huge numbers of jobs out there. But now, you can do some of those things again because you can now control a computer mouse with only your voice.
The program allows you to divide your screen into an arbitrary grid, and then "click" corners of that grid, all by speaking words. Combined with text-to-speech software, a computer can be operated entirely your voice, which would be pretty handy if you for some reason no longer have hands. I can also see this linking up with a domonics system, in which you can command "open door," and it does, "fill the bathtub with 90 degree water," and it happens (this would be the Fahrenheit scale, as 90 degrees Celsius would cause serious burns), "wash my back" and it gets scrubbed down. Within the confines of this type of house, the lack of hands is no longer an obstacle. In the outside world, prosthetics would still be necessary.
This system currently only runs on OSX, but if the applescript component could be ported to Perl, or another openly available language, then this could be ported to other systems as well. Way cool.

Father's day
June 17th is father's day in the United States, so I would like to take a moment to discuss my own father.
Ron the Ruthless was born shortly after World War II to my grandparents, a pilot and a school principal. He was an excellent scholar, quickly working his way through a fully funded scholarship at the Univerity of California, Berkley. While his major was officially Literature, he also studied nuclear physics, programming, civil engineering, and underwater basket-weaving to become generally the world's most ultimate scholar. After graduating, he met my mother, and they got married. He had two children with my mother. At the time of my birth, he was working as a school teacher in Chula Vista school district. He was also taking night classes in psychology, until he obtained a Master's degree about the time that I started elementary school.
He was quickly promoted to district psychologist, which he worked for 20 years. He then retired, and about five years after my brother left the family home, he moved to the South pacific with my mother to achieve his new life's goal, world conquest as overlord of the planet. He now daily wages war against his archrival, the overlord Sinister Steve.
His hobbies now include electronics, debate, reading, prank calling Kim Jong-un, war (usually against Steve), managing his current empire of currently five islands, choir, underwater basket-weaving, guitar, cello, spending time with his wife of 32 years (who is my mother) and opera.
Some aspects of this biography may be slightly inaccurate. Intentionally. Because it's funny, that's why.
I'd like to thank him for raising me to study hard, work hard, and encouraging me through my scientific endeavors through even the hardest of times. Happy father's day, dad.
To my readers, can you discuss your own fathers, and what makes them special?
