A new Kickstarter project called The Power Pot allows you to charge your small electronics while out camping or off the grid. It uses the concept of thermoelectric differences to generate the required electricity for most small electronic devices.
Here’s a quick video on the project.
Over at Kickstarter you can donate to help get the Power Pot to market. Here’s what David Toledo from Salt Lake City, Utah has to say about his project:
Hello, and thank you for checking out our project! The PowerPot is a cooking pot that doubles as a portable electric generator. It can be used indoors or outside and works with any fuel source. Unlike solar power, The PowerPot works day or night, rain or shine to bring you the electricity you need anytime, anywhere! We’ve reached our final stages of prototyping and it is time to bring this wonderful device to the market. With your help, we hope to get Power Pots into the hands of the people who need it most, and onto your own stove or campfire! People all over the world–whether they be herders in remote villages, backpacking enthusiasts, or city residents worried about potential power outages–can benefit from having a personal generator that makes electricity from cooking.
Simply put, The PowerPot transforms the heat from cooking into electricity with no moving parts. This is done using a technology called thermoelectric power generation. Thermoelectric technology was discovered in the early 1800’s, but found no consumer application in power generation due to the relatively high power needs of the devices in use at the time. However, times have changed. Today, nearly everyone uses microelectronics-based devices (smart phones, mp3 players, GPS units, etc.) which consume less than 5 watts of power.
Paul and I are both materials science engineers and avid campers. We came up with the concept of the PowerPot 5 years ago, because as much as we love the silence and solitude of the great outdoors, we wanted the option to listen to music and to charge our electronic gizmos while we were away from the power grid. We also wanted a power source that is lightweight, has no moving parts, and most importantly, is reliable and easy to use. After many prototypes, we have created a PowerPot that meets all of our criteria. Now after extensive field testing, we are confident it will satisfy other users as well.
Right now, we are launching two models, the PowerPot V and the PowerPot X, which respectively produce 5 and 10 watts of usable electricity. The power output of each PowerPot scales with size. So, we are also developing a higher power model called the PowerPot XV, with output of up to 15 watts. All models generate enough power to charge 2+ smart phones, mp3 players, or LED lights at a time. The larger models (PowerPot X and XV) produce enough power to charge larger devices such as tablets.
The PowerPot V is a typical backpacking type cooking pot, with thermoelectric technology attached to the base that makes it a 5W generator. This model holds 1.5 quart (1.4 l) and is lightweight, made from hard anodized aluminum, weighing in at only 12oz. With no moving parts, it will withstand miles of trekking, wherever you decide to take it. The PowerPot V is a simple, yet versatile and highly portable power solution, which will allow you to power 2-3 USB devices at a time. Only heat and water are required for the magic to happen. Besides making a perfect addition to your next backpacking/camping trip, the PowerPot V should also be part of your home emergency preparedness kit. The PowerPot V takes up little shelf space, has an indefinite shelf life, and it can be used indoors or outdoors, day or night, rain or shine, and on any heat source sufficient for cooking. You can store everything you need for a ready-to-go on-demand generator right inside the pot.
The PowerPot X is a typical kitchen-style pot, with integrated thermoelectric technology that makes it a 10W generator. The PowerPot X gives users enough electricity to power several handheld devices at a time, or larger devices such as tablets. The PowerPot X holds 2 (1.9 l) quarts of liquid, and is sized for a small family. Just like the PowerPot V, the PowerPot X has no moving parts, and has an indefinite shelf life. This model works well on a gas range, providing charging power and lighting at home during power outages.

With the many TVs that are available on the market, it can be difficult for many shoppers to choose the right model for their needs. Not only do televisions come in all different sizes and with many different features, but they also come in different formats. For example, many television shoppers have a difficult time determining the difference between LED and LCD televisions, and some wonder which would be a better fit for them. Although both types of televisions can provide large screens, stunning picture quality and lots of features, there are a few key differences. By understanding these differences, TV buyers can choose the type that is right for their families.
What is the Difference Between LED and LCD?
The main difference between LED and LCD televisions is the lighting that is used to illuminate their screens. Technically, LED televisions are still LCD TVs because they use a liquid crystal display as well.
The difference, however, is the type of bulb that is used in each TV. Traditional LCD televisions use fluorescent lamps behind their screens to provide picture. Alternatively, LED televisions use something called Light Emitting Diodes, which is a much more cutting-edge form of backlighting technology.
Which Has a Better Picture Quality?
Although there are plenty of LCD televisions with a stunning display, LED televisions do offer a better picture when the two are placed side-by-side. This is because the technology that is used in LED televisions is more advanced and can adjust the picture on the screen much more effectively.
Therefore, those who are interested in the best possible picture quality will probably want to look into an LED TV. However, there are lots of LCD models out there that provide a truly stunning picture; in fact, with many LCD televisions, those who don’t look at them beside an LED TV will not be able to tell the difference.
LED vs. LCD: Which Is More Energy Efficient?
For those who are concerned about the environment or want to reduce their electric bills, an LED television might be a better choice. Since these televisions use a newer type of technology, they can provide viewers with a better picture quality while still using less energy.
Which is Better for Video Games?
As many people who play video games know, it is highly possible for pictures to “melt” into a television screen permanently after hours upon hours of use. For those who are planning on using their televisions for a lot of gaming, LCD televisions might be a better choice. An LCD TV has less of a chance of “burning in,” but it is still a good idea for gamers to turn off the game for a little while to prevent this from occurring.
Those who plan on using their televisions as an alternative to a monitor for their computer should also consider an LCD to help prevent the possibility of a burn-in.
Overall, both LED and LCD televisions can function wonderfully. However, those who are interested in optimal energy efficiency and who crave the best picture quality possible, an LED television might be the best option. For gamers or those who want to save a few bucks on their purchases, however, an LCD television can provide a great experience for a slightly lower price tag.

Currently, the institute encompasses seven research groups.


Informatics gets boost in research capabilities with equipment donation
Integrated Computer Solutions, a Montgomery-based information security and technology consulting firm, recently donated approximately $70,000 in cutting-edge computer equipment to the Informatics Institute to help further the institute’s research mission.
The Informatics Institute was founded in 2008 to foster research and education in the field of automation of information processing in diverse scientific fields and assurance sciences. The institute recently became a degree-granting entity as a part of the School of Sciences.
The equipment donated by ICS includes enterprise-class servers and storage and network security appliances.
According to Dr. Mehmet Sahinoglu, the institute’s director, this equipment will be an excellent addition to the institute’s facilities.
“The cyber-security related equipment will be used to set up prototype laboratory ambiance as a support system to the forthcoming grant prospects,” said Sahinoglu.
"The institute’s goals and those of ICS are well aligned around developing the skills and capabilities of students wanting to become IT professionals. Therefore, the donation was a natural extension to achieving this shared objective,” said ICS President Steve Goldsby on why his company chose to make such a large contribution to the institute.
“Additionally, as the institute was recently elevated to a degree program, we know that the equipment donated will be put to great use by the institute as it prepares students to become leaders in the field of information and network security," Goldsby said.
The institute’s Master of Science in Cybersystems and Information Security program will offer instruction and research opportunities that provide graduates with the necessary knowledge and skills to effectively assess, develop and manage secure information networks and respond to newly developed threats. Recent cyber attacks in both the domestic and international arenas suggest that cyber security will continue to be a regional, national and global concern.
“The CSIS students will benefit from ICS’ donation in their lab experience when the program starts in 2010,” said Sahinoglu. “The Informatics Institute staff extends their sincere appreciation to ICS, and specifically Mr. Goldsby, for this generous donation.”

I attached a keychain “spy” camera that takes snapshots and HD video to an Estes model rocket. I suspect with a C motor it’ll reach about a thousand feet. The hope is the camera will stay in place in a slot I cut to hold the camera in the nose cone. The parachute is merely a backup if the camera manages to fling itself loose from the rocket. There’s a 2 gig mini-sdcard salvaged from an old cellphone. I am not sure it will survive launch, or even be able to take video of rapidly changing scenes. But it will be fun either way.
I am guessing the rocket will go about 1000 feet in 6 seconds which means the rocket will average 113 mph. It will be interesting to see if both the software and the hardware of the camera can handle the sudden acceleration.


This light sculpture illuminates pi, a number that has brought enlightenment to students and scholars of math and science throughout the ag...es.
A mathematical technique warps the cutouts on the curved sides of the cylinder such that an unwarped shadow is cast on the floor. The digits of pi swirl along the arm of an Archimedes spiral; the length of the sequence before it fades a measure of your printer's ability to capture fine details.
3d model print parameters
*This project involves soldering, small-parts, electrical components and an extremely bright LED. You assume all risks and liabilities should you wish... to undertake it.* **Print it:** The lamp consists of two parts, a base and a lid. The cutouts on the base are larger towards the bottom of the lamp and get smaller further up. Because of this, you should get a good print regardless of the resolution of your printer -- a high resolution print will extend length of the sequence that is legible, but is not necessary. I made my print on a consumer FDM printer at 0.16mm layer height and retraction enabled **Light it up:** I used a 20mm high-power green LED star for my build. A pack of ten costs about $5 on eBay. The LED is rated at up to 3W. I've found running it at around half that seems to give good results without overheating and without needing a heat sink. Be careful not to look directly at the LED. It is extremely bright and could damage your eyes. **Power it:** A green high-power LED star will run off 2.2-3.4V, so you will need a suitable power supply. I used a bench-top adjustable power supply for testing, but in my final build I used a recycled 12V wall wart combined with a adjustable micro DC-DC step-down converter from e-bay. The particular one I used was listed as "10pcs Mini DC-DC Converter Step Down Module Adjustable Output 1-17V for RC PLANE" and sold by axeprice. It was small enough to fit inside the lamp, but you could also mount a larger module outside of the lamp. The converter has an adjustable output voltage, so you can tune the brightness of the LED and balance it against heat output. You could also get fairly good results with a two AA batteries and maybe some resistors, but it would not run as long. **Choosing the correct voltage:** Because in my build I did not use resistors, picking the correct voltage for the LED is very critical. The LED will begin conducting at a certain voltage, but beyond that, the current will increase very sharply. The sweet spot is only a few tenths of a volt beyond the initial conduction point. I recommend using a bench-top power supply with a variable voltage knob and an integrated ammeter to determine the voltage that causes enough current to run through the LED without overheating (about 0.4A for a 3W LED). Once you have determined the correct voltage, re-check it using a multimeter and write it down. You will use this voltage to tune the DC-to-DC converter during assembly. **Assemble it:** Assembly consists of soldering the various parts together. Be very careful about the polarity of the components. The following build sequence worked for me: * Cut the plug off your AC wall wart and separate the two wires to give a slack of about six inches. * Feed the two wires through the guide holes on the lid to the other side. * Solder the wires to the input pads of your DC-to-DC converter (In+ and In-). Use a multimeter to determine which wire is positive and which is negative if you cannot tell. Polarity is very important. * Plug in the AC wall wart and using the multimeter adjust the voltage on your DC-to-DC converter to the value you determined above. If you do not have a multimeter, set it to 2.3V to start -- this will keep you from blowing out your LED when you first power it up. * Solder two short lengths of wire to the LED + and - pads. A set of bench top helping hands is very good for this task. * Solder the other end of the wires to the output terminals of the DC-to-DC converter. Mind the polarity -- if you get it reversed, the LED will not light. * Use double sided foam tape to stick the DC-to-DC converter and the LED to the inside of the lid. The LED needs to be perfectly centered for the shadows to cast correctly. **Tune it:** Once you first plug it in, run your lamp without the base attached and monitor it to make sure the LED is not getting too hot. Let it run a couple minutes and checking regularly to make sure that it is not getting too hot to the touch. If it is, dial back the voltage on the DC-to-DC converter. You want the LED to run warm, but not hot enough to melt the plastic or cause a fire hazard. Do not run the lamp unattended until you have monitored it for several hours to make sure heat is not a problem. **Customize it:** This design is fully customizable. Be sure to check it out in the Makerbot customizer! **Credits and Inspiration:** * The idea of depicting PI in a spiral came from "Tower of Pi" by Roman Hegglin * Inspired by stereographic projection ideas of Henry Segerman and Saul Schleimer

Researchers at the University of Grenoble in France recently released the results of a clinical trial in which a paralyzed man was able to walk with the help of an exoskeleton. The patient, a 28-year-old French man identified as Thibault, was able to control the exoskeleton with his mind. The study’s authors say this shows operating the robotic system is possible for people with tetraplegia, the loss of control of both arms and legs.
The whole-body exoskeleton, a four-limb robotic system mounted to a ceiling harness for balance, was part of a two-year trial funded by Clinatec, a French biomedical research company specializing in neuroscience. While the current state of the system is not patient ready, researchers are enthusiastic that the trial demonstrates the technology is possible for an algorithm that interprets brain signals and turns them into physical movement.
“Ours is the first semi-invasive wireless brain-computer system designed for long-term use to activate all four limbs,” said Professor Alim-Louis Benabid, President of the Clinatec Executive Board and Professor Emeritus at the University of Grenoble in a press release. “Previous brain-computer studies have used more invasive recording devices implanted beneath the outermost membrane of the brain, where they eventually stop working. They have also been connected to wires, limited to creating movement in just one limb, or have focused on restoring movement to patients’ own muscles.”
A paralyzed man was able to walk with the help of an exoskeleton and ceiling-attached harness using brain-controlled sensors. Photo Courtesy: mashable.com
Thibault controlled the exoskeleton through two sensors implanted between his skin and brain. The sensors record brain activity in the sensorimotor cortex, the part of the brain that controls movement and sensation. An algorithm was trained to interpret the signals and translate them into movement. He started out using the mind sensors to play games like Pong, eventually moving to more complex movements like turning his wrist, and finally walking.
The trial is ongoing, with three more patients recruited. Researchers’ next goal is to allow a patient to walk and balance without needing the ceiling suspension system. Further studies will also shed light on brain function, delving deeper into how the sensorimotor cortex creates the signals needed to produce the movements.
“Our findings could move us a step closer to helping tetraplegic patients to drive computers using brain signals alone, perhaps starting with driving wheelchairs using brain activity instead of joysticks and progressing to developing an exoskeleton for increased mobility,” said Professor Stephan Chabardes, neurosurgeon from the CHU of Grenoble-Alpes, France.
At Protolabs, we’re interested in these innovations because we work with medtech companies and organizations in this specialty, including Parker Hannifin and the University of Houston, which also have developed exoskeleton technologies.
Eye on Innovation is a monthly look at new technology, products, and trends.

Hello everyone. I’m going to start a new tutorial series on pic programming, which could be very useful for beginners. First, I wish to give a brief description on microcontrollers and then move on to the next section, PIC16f84a programming using C language. Once you have understood the basics of the PIC, let’s move on to PIC18 series.
What is a microcontroller?
In brief, microcontroller is a kind of a small computer, packed in a small IC. Think of an ordinary computer for an instance. They come with a RAM, ROM, CPU, Hard drive, Input/Output devices, ports and a mainboard to connect them all together. In a microcontrollers also, all those things are there, but they are built in and sealed. So it’s not possible to change hardware configurations as we wish.
Applications of microcontrollers
Nowadays, there are microcontroller based systems in almost all of the electronic appliances. They are there in TV sets, DVD players, microwave ovens and everything. Even the remote controller of a TV or the LCD display of a microwave oven are driven by microcontrollers. So it’s very important for any IT/ electrical/electronic professional to have a good knowledge about these devices.
This is a small microcontroller, manufactured by “Microchip”, one of the leading semiconductor manufacturers. There are 18 pins, arranged as 9 in a side.
PORTA(RA0 to RA4)
PortA or RA is an I/O port, which could be used as an input or as an output. The port has 5 pins, so it could work as a 5 bit port, where the bit numbers are from RA0 to RA4.
PORTB(RB0 to RB7)
PORTB also similar to PORTA, except the fact that it has 8 bits.
OSC1 and OSC2(CLK IN and CLK OUT)
An external oscillator is connected to these pins. (In this case, we wish to use a 4MHz crystal oscillator.)
VSS, VDD and MCLR
VSS is the positive power supply of the PIC. VDD is the negative power supply pin. MCLR is used when we program the PIC microcontroller. However, it is normally connected to the positive power supply pin using a resistor.

George R. Carruthers
Most of the times the desperation and call for science comes from childhood. When children in a summer camp looked at the night sky of Milky Way Galaxy, the tiny but shining stars, the enormous picture of the sky, they found their luck of being part of the universe. That is when they said I would like to explore it. Said by author and theoretical physicist Dr. Michio Kaku, after interviewing about 300 scientists who invented the future in their laboratory, the age 10 is commonly called the goldilock zone to develop an interests in science.
Our story falls in George R. Carruthers, a African-American NASA inventor who led the team of inventing the far ultraviolet camera/spectrograph, as part of the mission of Apollo 16 in 1972. He grew up with interests in Physics, Science and Astronomy and became an telescope inventor at the age of 10. Although the telescope was not ideally matured, by taking cardboards and cheap lenses in use, you can’t require more for a child at that age.
He got his B.S. degree in Astronautic Engineering and M.S. degree in Nuclear Engineering and ph.D. in Astronautical and Astronomical Engineering in 1964. His great honor, which got him an award of National Medal of Technology and Innovation, is from the invention of the far ultraviolet camera/spectrograph, which would be able to absorb UV emissions on the moon. It was hard for scientists on earth to absorb UV because the earth atmosphere took away most of the UV emissions, but by doing that on the moon, there are a lot of data to be collected. Basically, they built a 50-pound, gold-plated camera that could catch the radiation from the upper half of the spectrum. The Apollo brought the camera to the moon and succeeded of collecting about 200 UV figures.
His other honors include Arthur S. Flemming Award, in 1970, Exceptional Achievement Scientific Award Medal in 1972, and Black Engineer of the Year Award 1987.
Watch this brief video where he is talking about his work.

When the ignition of your car is turned on, the battery passes power to the electric starter motor. If the power of the battery lessens, a spare battery is required from additional power boosting. Cables that are used for connecting the additional battery with the dead one are called jumper cables or the jump start cables. These cables are heavy gauge wire attached to the sturdy alligator clip on both the battery terminals and allow electricity to jump start car for use.
Battery jumper cables restore the voltage to the primary battery with low or dead battery. This cable transfers the electricity from the working battery with the help of the alternator and your dead battery.
Here you will get to know about the 5 reasons why you it is important to have a jumper cable:
1. Will not get stuck in the middle of the road if you have a Jump start cable
If you have a jumper cable with you then you will just need a host vehicle for boosting up your battery.
2. Save the tow charges
The tow charges are very heavy if you really wish to save your money from such unforeseen circumstances you must have a jumper cable with you.
3. Save you from the hassle of waiting for the car services
Jump start cable actually avoids you from waiting for the car services or wrecker service to come to your rescue.
4. You must always carry the battery jumper cable with you in your car
Because anything can happen without giving a warning. You can even help somebody who is stuck in such situation.
5. The direction of using the jumpstart cable
It is very simple and the output is also great so it is better to accompany this champion with you always and keep worries at bay forever.
If you are going to buy a jumper cable for your car, then you must be cautious and concentrate on some basic things like:
• Opt for reasonable battery jumper cables.
• Look for the gauge amount that should be 6 for an actual heavy duty cable. Lower gauge provides more power and charges quickly.
• The clamp must be very sturdy for a long life. Crocodile clamps are the best as they don’t slip off when attached to the battery terminals.
• Camp should have rubber coated handles so that the chances of shock also minimizes.
Hurry and buy jumper cables now. You can even purchase 12’cable for a basic reach as well depending upon your requirement. They are essential so don’t take this equipment lightly.

Instrument Detection Chemistry/Mechanism
Currently there are lots of new types of detection chemistry/mechanisms out there, probably too numerous to list, however, here is a short list of the ones I have come across:
- Voltage differential between reference and test probes. Lots of POC devices uses this type of detection system.
- Metal Complex Redox Reaction. Roche uses a organo-Ruthenium complex and when a voltage is applied the complex goes through a series of redox reactions to produce light. It's a little more complicated than the Acridan/Acridinium chemistry, but since you separate the liquid from the reaction vessel, you can get higher sensitivities.
- Acridinium or Acridan esters. Both Siemens and Abbott Laboratories use this type of chemistry on their systems.
- Fluorophores. These can be quite sensitive, however they are subject to lots of artifacts and these types of molecules can be very sticky and give rise to background issues. They also take a longer time to quantitate since they "glow" instead of "flash".
- Alkaline Phosphatase. This is a biological enzyme that removes a phosphate group from an organic molecule. There are organic subrates with attached phosphates that turn color and ones that can actually produce photons (similar to the Acridinium/Acridan molecules). The downside is that it takes time for the enzyme to act on the substrates which delays test results a little.
Now, there are some other detection technologies that I won't go into detail here, but currently, they have not proven to be robust enough for "lab quality" results. Here's a few of them:
- Quantum Dots - ~30 nm particles that exhibit band spectrum behavior.
- Magnetic Resonance
- Vibrational Frequency Changes
- Carbon Microfibers
- Refractive index changes

Space exploration has always been a fascinating topic for scientists and engineers alike. With the advancement of technology, the possibilities of space exploration have become even more exciting. One of the most promising technologies is nuclear-powered spacecraft. Nuclear-based systems can have less mass than equivalent power solar cells, allowing for more compact spacecraft that are easier to orient and steer in space.
In the case of manned spaceflight, nuclear power concepts that can power both life support and propulsion systems can reduce both cost and flight time. Nuclear propulsion includes a wide variety of propulsion methods that use some form of nuclear reaction as the primary energy source. The idea of using nuclear material for propulsion dates back to the beginning of the 20th century. In 1903, it was hypothesized that radioactive material, radium, could be a suitable fuel for engines to power cars, planes and ships. Wells picked up this idea in his 1914 work of fiction The World Set Free. Nuclear propulsion systems will not activate during launch.
Despite the name, nuclear-powered and manned spacecraft will have a large asterisk; they will be launched with chemical propulsion systems. The nuclear reactor will only work once the vehicle has left the Earth's atmosphere. This design feature is intended to minimize the risk of release of radioactive materials in the event of an accident on the launch pad. Nuclear reactors use controlled nuclear fission in a chain reaction. With the use of neutron absorbers, the reaction rate is controlled, so the power depends on the demand.
The Cassini spacecraft was carrying three RTGs that provided 870 watts of power from 33 kg of plutonium oxide 238 while exploring Saturn. And so, the satellite was equipped with a small, efficient but powerful nuclear reactor, powered by approximately 50 kg of weapons-grade uranium 235. In early 1959-73, there was a United States nuclear rocket program, the Nuclear Engine for Rocket Vehicle Applications (NERVA), which focused on replacing nuclear energy chemical rockets for the later stages of launches. After a lapse of several years, there has been a resurgence of interest in the use of nuclear fission energy for space missions. Uranium used in commercial power plants is usually enriched by up to five percent, which is insufficient for nuclear propulsion systems. Both will take you from A to B, but a Prius will get you there more efficiently, while a Corvette will get you there quickly using more gas, Ahmed said of the difference between nuclear and chemical propulsion systems for space travel.
In addition to solar panels and batteries, a nuclear power source will be installed in the rover so that it can operate up to 400 kilometers, even in the shade. However, nuclear electric propulsion systems are also expected to be much more efficient than traditional chemical propulsion systems. The argument in favor of nuclear space propulsion depends entirely on the supposed imperative of sending humans to Mars. Nuclear propulsion systems for space exploration, if they materialize, are expected to offer significant advantages, including the ability to send spacecraft further, in less time and more efficiently than traditional chemical propulsion systems. In the late 1980s, the focus was on nuclear electric propulsion (NEP) systems, where nuclear reactors are a source of heat for ion electrical units that eject plasma from a nozzle to propel spacecraft that are already in space. However, attaching what is equivalent to a nuclear reactor to a human-occupied spacecraft is not without risks.
Heatpipe Power System (HPS) reactors are compact, fast reactors that produce up to 100 kWe for about ten years to power a spacecraft or planetary surface vehicle. NASA would also need to design the spacecraft to protect astronauts from the nuclear reactor itself. This could be done by using advanced materials to protect them from radiation or placing homes as far away from it as possible. A more radical goal of Prometheus was to produce a space fission energy system (SPF) such as those described above, both for power and propulsion, that was safe to launch and that would operate for many years at a much higher power than RTGs. Nuclear propulsion systems will incorporate physical shields into their engineering designs, says Calomino. Exploring these possibilities could open up new frontiers in space exploration and make it possible for humans to explore further than ever before.


Container networking refers to the ability for containers to connect to and communicate with each other, or to non-Docker workloads.
A container has no information about what kind of network it's attached to,
or whether their peers are also Docker workloads or not.
A container only sees a network interface with an IP address,
a gateway, a routing table, DNS services, and other networking details.
That is, unless the container uses the
none network driver.
This page describes networking from the point of view of the container,
and the concepts around container networking.
This page doesn't describe OS-specific details about how Docker networks work.
For information about how Docker manipulates
iptables rules on Linux,
Packet filtering and firewalls.
By default, when you create or run a container using
docker create or
the container doesn't expose any of its ports to the outside world.
-p flag to make a port available to services
outside of Docker.
This creates a firewall rule in the host,
mapping a container port to a port on the Docker host to the outside world.
Here are some examples:
|Map port |
|Map port |
|Map port |
|Map TCP port |
Publishing container ports is insecure by default. Meaning, when you publish a container's ports it becomes available not only to the Docker host, but to the outside world as well.
If you include the localhost IP address (
127.0.0.1) with the publish flag, only the Docker host can access the published container port.
$ docker run -p 127.0.0.1:8080:80 nginx
Hosts within the same L2 segment (for example, hosts connected to the same network switch) can reach ports published to localhost. For more information, see moby/moby#45610open_in_new
If you want to make a container accessible to other containers, it isn't necessary to publish the container's ports. You can enable inter-container communication by connecting the containers to the same network, usually a bridge network.
By default, the container gets an IP address for every Docker network it attaches to. A container receives an IP address out of the IP subnet of the network. The Docker daemon performs dynamic subnetting and IP address allocation for containers. Each network also has a default subnet mask and gateway.
When a container starts, it can only attach to a single network, using the
You can connect a running container to additional networks using the
docker network connect command.
In both cases, you can use the
--ip6 flags to specify the container's IP address on that particular network.
In the same way, a container's hostname defaults to be the container's ID in Docker.
You can override the hostname using
When connecting to an existing network using
docker network connect,
you can use the
--alias flag to specify an additional network alias for the container on that network.
By default, containers inherit the DNS settings of the host,
as defined in the
/etc/resolv.conf configuration file.
Containers that attach to the default
bridge network receive a copy of this file.
Containers that attach to a
use Docker's embedded DNS server.
The embedded DNS server forwards external DNS lookups to the DNS servers configured on the host.
You can configure DNS resolution on a per-container basis, using flags for the
docker run or
docker create command used to start the container.
The following table describes the available
docker run flags related to DNS
|The IP address of a DNS server. To specify multiple DNS servers, use multiple |
|A DNS search domain to search non-fully qualified hostnames. To specify multiple DNS search prefixes, use multiple |
|A key-value pair representing a DNS option and its value. See your operating system's documentation for |
|The hostname a container uses for itself. Defaults to the container's ID if not specified.|
/etc/resolv.conf file on the host system contains one or more
nameserver entries with an IPv6 address, those nameserver entries get copied
/etc/resolv.conf in containers that you run.
For containers using musl libc (in other words, Alpine Linux), this results in a race condition for hostname lookup. As a result, hostname resolution might sporadically fail if the external IPv6 DNS server wins the race condition against the embedded DNS server.
It's rare that the external DNS server is faster than the embedded one. But things like garbage collection, or large numbers of concurrent DNS requests, can sometimes result in a round trip to the external server being faster than local resolution.
Custom hosts, defined in
/etc/hosts on the host machine, aren't inherited by containers.
To pass additional hosts into container, refer to
add entries to container hosts file
docker run reference documentation.

The amplitude of a sound wave can be measured much more easily with pressure (a bulk property of a material like air) than with displacement (the displacement of the submicroscopic molecules that make up air). Kids learn about the properties waves in the science of physics including amplitude, wavelength, frequency, period, and speed. Amplitude, wavelength and frequency. ... Energy of a wave and Planck formula. The amount of energy carried by a wave is related to the amplitude of the wave. As discussed earlier in Lesson 2, the amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. Where the distance covered by Amplitude, period, frequency and wavelength of periodic waves. If the sound intensity is more, then the amplitude of the sound wave is more. Wave Period: Definition & Formula ... Amplitude measures how much energy is being transported by the wave. 102 - Wave Amplitude In this video Paul Andersen explains how the amplitude of a wave is a measure of the energy of the wave. Amplitude (a) of a wave is how big the wave is or the energy of the wave. Amplitude, Period, Phase Shift and Frequency . Amplitude. A high energy wave is characterized by a high amplitude; a low energy wave is characterized by a low amplitude. For an object in periodic motion, the amplitude is the maximum displacement from equilibrium. I don't understand how to use a proportionality. A wave can The Doppler Effect formula s s o o f v v v v f ... then the wave crests pile up on top of each other forming a The maximum height of the wave is called its Amplitude. It is represented by A and is known in decibels (dB). Amplitude Formula Questions: 1) A pendulum is swinging back and forth. A variables amplitude is a measure of its change over a single period. Typically, the power supplied by a wave is averaged over many periods; since the wave is not at peak amplitude for most of oscillation, it does not make sense for the peak amplitude to be the only important factor. You need to know about these quantities used in waves - what they mean, the symbols used for them and the units used to measure them. 4. ... Propagation of the transverse wave is same as that of a sine wave. Precalculus Examples. You should understand what is meant by the amplitude, wavelength and frequency of a wave. Pulse amplitude. Preprint typeset in JHEP style - PAPER VERSION GRAVITATIONAL WAVE PHYSICS Kostas D. Kokkotas Department of Physics, Aristotle University of Thessaloniki The maximum height perceived in the wave is termed as Amplitude. The total number of waves passing through a particular time is called as frequency. A waves amplitude is the distance measured from the rest position to the crests top or the troughs bottom. Waves and the One-Dimensional Wave Equation ... so = maximum particle displacement or amplitude = distance over which the wave begins to repeat These include the basic periodic motion parameters amplitude, ... frequency or wavelength in the active formula above. Amplitude Transverse Wave. Strictly speaking, this is no longer amplitude since there is the possibility that a constant (DC component) is included in the measurement. The trough is the part of the wave that slopes downward, and the crest is the part of the wave that points upward. Why is energy in a wave proportional to amplitude squared. A modulating wave, which in theory could be another sine wave, typically at a lower audio frequency is superimposed upon the carrier. A useful solution to the wave equation for an ideal string is. This relationship is always true: Whatever number A is multiplied on the trig function gives you the amplitude (that is, the "tallness" or "shortness" of the graph); in this case, that amplitude number was 3. Wavelength Formula Questions: 1) The speed of sound is about 340 m/s. When is it appropriate to use this formula? The amplitude measures the height of the wave from the mid-line, which can be calculated using amplitude formula.


The rc_cube comes with several on-board software modules, each of which corresponds to a certain functionality and can be interfaced via its respective node in the REST-API interface.
The rc_cube offers the possibility to connect multiple 3D cameras such as the rc_visard. The image data from each device is processed in a separate camera pipeline, which consists of several different software modules. The modules inside each pipeline are pipeline specific, which means that they can have different parameters for each pipeline. The modules running outside the pipelines are global and provide data for all modules in all pipelines. An overview is given in Fig. 9.
The rc_cube’s pipeline-specific software modules can be divided into
- Detection modules
- which provide a variety of detection functionalities, such as grasp point computation and object detection,
- Configuration modules
- which enable the user to perform calibrations and configure the rc_cube for specific applications.
The modules that are global for all camera pipelines running on the rc_cube are the
- Database modules
- which enable the user to configure global data available to all other modules, such as load carriers, regions of interest and grippers.

Mac Mini (stylized as Mac mini) is a small form factor desktop computer developed and marketed by Apple Inc. As of 2022[update], it is positioned between the consumer all-in-one iMac and the professional Mac Studio and Mac Pro as one of four current Mac desktop computers. Since launch, it has shipped without a display, keyboard, and mouse. The machine was initially branded as "BYODKM" (Bring Your Own Display, Keyboard, and Mouse) as a strategic pitch to encourage users to switch from Windows and Linux computers.
A server version of the Mac Mini that is bundled with the Server edition of the OS X operating system was offered from 2009 to 2014. The Mac Mini received generally tepid reviews except for the Apple silicon model, which was praised for its compatibility, performance, processor, price, and power efficiencies, though it drew some occasional criticisms for its ports, speaker, integrated graphics, non-user-upgradable RAM and storage, and the expensive cost to buy associated accessories and displays.
The Mac Mini G4 has two USB 2.0 ports and one FireWire 400 port. Networking is supported with 10/100 Ethernet and a 56k V.92 modem, while 802.11b/g Wi-Fi and Bluetooth were additional, build-to-order options. External displays are supported via a DVI port, and adapters for VGA, S-Video, and composite video output were available. The system contains a built-in speaker and an 1/8-inch stereo mini jack for analog sound output. The new Wi-Fi card no longer used an MMCX-Female connector for the antenna, as do prior models, but rather a proprietary Apple one.
In February 2006, Apple announced the first Intel Mac Mini, as part of the Mac's transition to Intel processors. Based on the Intel Core Solo CPU, it is four times faster than its predecessor PowerPC G4. An updated server version of the machine was released in October 2009, having been marketed as an affordable server for small financial and academic uses; this model omitted the optical drive and used a hard drive instead.
The 2006 and 2007 models are fitted with 32-bit Intel Core Solo CPUs that is upgradable with the 64-bit Core 2 Duo processors. The 2006 and 2007 Merom-based Mac Mini models were supplied with socketed CPUs; the 32-bit processor can be removed, and replaced with a compatible 64-bit Intel Core 2 Duo processor. Models manufactured in and after 2009 had their CPUs soldered onto a logic board, preventing its upgradability. The upgrades make the 2006/2007 models perform better than the 2009 models. Geekbench has shown the 2.33 GHz Core 2 Duo fitted Mac Mini with 2 GB of RAM has a score of 3060 whereas a late 2009 Mac Mini with 2 GB of RAM has 3056 making the two machines fairly comparable.
The built-in Intel GMA was criticized for producing stuttering video despite supporting hardware accelerated H.264 video playback, and disappointing frame rates in graphics-intensive 3D games. Early and Late 2009 models corrected these performance issues with an improved NVIDIA-based GeForce 9400M chipset.
The Intel-based Mac Mini includes four USB 2.0 ports and one FireWire 400 port. The I/O ports were changed with the early 2009 revision, adding a fifth USB 2.0 and swapping the FireWire 400 port for a FireWire 800 port. An infrared receiver was added, allowing the use of an Apple Remote. Bluetooth 2.0+EDR and 802.11g Wi-Fi became standard and the Ethernet port was upgraded to Gigabit. A built-in 56k modem was no longer available. The 2009 models added 802.11 draft-n and later 802.11n Wi-Fi, and Bluetooth was upgraded from 2.0 to 2.1. External displays are supported through a DVI port. The 2009 models have Mini-DVI and Mini DisplayPort video output, allowing the use of two displays. The Mini DisplayPort supports displays with a resolution up to 2560×1600, which allows use of the 30-inch Cinema Display. The Intel-based Mac Mini has separate Mini-TOSLINK/3.5 mm mini-jacks that support both analog audio input and output, and optical digital S/PDIF input and output.
With the M1, this Mac Mini has a 3x faster eight-core CPU, a 6x faster GPU, and 15x faster machine learning performance than its predecessor, the base 2018 model. Options for more than 16 GB of RAM are not available on M1-based systems. Support for external displays is reduced to one display over USB-C/Thunderbolt, though a second display can be connected using HDMI; the previous Intel-based model could drive two 4K displays over USB-C/Thunderbolt. On April 20, 2021, 10 Gigabit Ethernet with Lights Out Management was added as a built-to-order option. Its internal cooling system has a thermal-based design that according to Apple performs five times more quickly than the best-selling Windows-based desktop computer in its price range.
Pre-2009 models have a video connector that is compatible with DVI, HDMI (video only), SVGA, S-Video, and composite video with appropriate adapters; for audio output, it has both the analog mini-headphone port and a digital optical fiber port. The addition of a HDMI port on the 2010 Mac Mini simplified connection to high-definition televisions and home theater AV receivers. The HDMI port supports video resolutions of up to 1080p and eight-channel, 24-bit audio at 192 kHz, and Dolby Surround 5.1 and stereo output. The 2014 model added 4K output, and the 2018 model supports Dolby Atmos, Dolby Vision, and HDR10, and uses the macOS Catalina operating system.
To provide sufficient storage for photos, music, videos, and more, we added an 8TB OWC miniStack. This external drive works great with any Mac mini! It matches the looks of the mini and sits directly underneath the computer.
This screenshot shows Phile Audio copying music from a CD and saving it to the Music folder on the miniStack. Phile Audio gathers the track info, album genre, and year of the release. However, you may need to do some searching to find album cover art. Wikipedia is a great source of album covers. Download the art, then drag and drop it to the Phile Audio user interface to add the album cover.
Now that your content is loaded, connect the Mac mini media server to your TV. Since 2010, all Mac minis have provided an HDMI-out port. HDMI is your gateway to connecting the computer and TV since one cable does the job for sound and video. The HDMI port on 2014 and later Mac minis supports 4K resolution at 30 frames per second. There is also a 3.5mm stereo audio port for connecting an amplifier or speakers other than those on your TV. 2b1af7f3a8
