Earth's "twin," roughly the same direction as Vega (famous in "Contact"), is 600 light-years away, and perhaps covered in water, say the Kepler team.
About 2-and-1/2 times the size of Earth, and not quite so far from its own very Earth-like sun, which is located in the direction of Cygnus (the "Northern Cross," visible in the night sky from the Northern Hemisphere during the summer), Kepler 22-B is located in the direction the fictional aliens hailed from in the film "Contact" (1997, based on the book by Carl Sagan), just south of the North Pole.
Kepler 22-B orbits its sun with a 290-or-so day Earth-like year. It orbits however at about 600 light-years from Earth, roughly 24 times the distance of the advanced civilization in "Contact," which came from somewhere near the hot blue star Vega.
Kepler 22-B's average temperature is believed to be around 72 degrees fahrenheit. Since it's bigger than Earth, there's no reason its gravity won't hold both water and rocks.
Although NASA won't be able to get more data till the Northern Cross is visible at night next summer, NASA is sure it has found a planet, based on observations it made beginning May 12, 2009, and ending March 14, 2011, according to the report submitted by Borucki et. al.
First "Earth Twin" Discovered?
This is the first Earth-like planet found to date, and one of 54 planets in the "life zone" (where liquid water is possible) supposedly found by Kepler. Other habitable planets have been found previously by other means, beginning with Gliese 876-B and Gliese 876-C both orbiting the star Gliese 876 about 15 light-years away in the direction of Aquarius. These were discovered in 1998 and 2001 respectively. Gliese 589-D (orbiting the star Gliese 581) is perhaps the first terrestrial mass planet in or near the habitable zone. Like the fictional aliens in "Contact," it's just over 20 light-years away, but in the direction of Libra, quite a different direction than Kepler 22-B. All three of these planets have much shorter years than does Earth, whereas Kepler 22-B's year is about the same length as Earth's. Except that it is slightly larger than Earth, Kepler 22-B seems to be truly a "twin."
Information about Gliese 589-D was revised to include it in or near the habitable zone in 2009. Of the thousands of "planet candidates" it has surveyed, the Kepler telescope mission has, to date, confirmed about 33 (three more were confirmed by the Kepler team on the ground).
Messages to the Stars?
According to Wikipedia's information on Gliese 581-D, in 2008 the website Bebo beamed a message to Gliese 581-D which will (hopefully) arrive in 2029. Kepler 22-B, however, is apparently too far from Earth for it to receive our messages with current transmitters, according to Katherine Noyes (Dec. 5, 2011).
SETI, with new funds from both the web and the U.S. Air Force, will nevertheless direct its searches for signals so as to include the newly discovered Kepler 22-B. One possible option might be to send messages, albeit not people, to star regions near or far via "wormholes" (tunnel-like paths through space) such as the one used by the heroine of "Contact" for her eighteen-hour round trip to Vega. However no one has suggested sending either by wormhole yet. In any case, it might be more difficult to send people than signals this writer speculates: according to physicists Ford and Roman (January, 2000), who have studied quantum mechanics and black hole physics for a number of years, for a wormhole to be stable enough for travel through it, it would have to have a throat with a radius no greater than the "Planck length," the distance at which waves start to behave like particles.
How Kepler Works
The Kepler Space Telescope, launched in March of 2009, has a lens diameter of just under a meter, trained on the Milky Way in the direction of Cygnus and Lyra (a location chosen for its many stars). It locates planets' transits of their suns (the star a planet orbits is dimmed slightly when it transits, and measuring the tiny change in its luminosity is something akin perhaps to finding a "needle in a haystack"). The Kepler observatory orbits the sun a bit beyond the earth, with a 371-day orbital period.
Cost and Funding
Kepler's cost is relatively low at around 600 million U.S. dollars total. This cost includes 3.5 years of operation. (Each year of operation costs about 20 million U.S. dollars.) Funding is slated to run out in less than a year, in November of 2012. Its advocates hope to extend funding through 2016.
Other Space Telescopes: the Webb
The much more powerful 6.5 meter Webb Space Telescope, the official Hubble successor (the Hubble will "retire" in 2013), which won't be ready till 2018 if then, is expected to cost around 8 billion U.S. dollars, if it stays within budget. Of course the Webb may be able to see into the darkest reaches of the universe yet and get a real look at some planets we've "seen" only through their effects on other celestial bodies. The Webb is slated to get about $529 million in funds for 2012 according to John Matson (Nov. 17, 2011).
Like the European Space Agency's Herschel, the Webb will orbit about one-and-a-half million kilometers from Earth, at a point where both Earth and sun pull on it equally. Its lens diameter is slated to be about twice that of the Herschel (meaning it will gather around three or four times as much light) and three times that of the Hubble (gathering about seven times as much light). Both the Herschel and Webb are designed to operate primarily at infrared wavelengths, but the Webb will operate at a slightly higher wavelength, with its focus on receding stars and distant galaxies. The Webb is expected to create 2000 jobs, many in Maryland.
Telescopes: Advantages From Space
Telescopes see better than people because their wide lenses capture more light than the human eye. The advantage of having telescopes in space is that they orbit above the atmosphere's interference, which tends to cause light coming across it to "flicker;" and also above the interference of background light (glare) on Earth. For an idea of how much interference from light on Earth there is, see NASA's "Lighting Up the Ecosphere." In spite of its being in space, the Kepler observatory has encountered a great deal of variation in the light it has received, much more than expected.
Infrared and Ultraviolet Observation
Observations of space in the infrared radiation bands are virtually impossible from Earth. Both space dust, which is heated by hot gasses, and distant galaxies, which tend to be receding from Earth at high speeds so that their light is red-shifted, emit radiation in the infrared bands. This radiation is used by astronomers to look back into the earlier days of the universe, and to get an idea of how much total matter there is including dust and "dark matter." Like infrared radiation, most ultraviolet and gamma radiation is absorbed by the atmosphere and cannot be easily observed from Earth either. Much ordinary stellar variation occurs at these wavelengths but planetary transits tend to cause more variation in the visible spectrum.
The Hubble, which makes use of the popular "Cassegrain" reflector, currently captures light at visible, infrared, and ultraviolet wavelengths, but not all at once. It orbits at the top of Earth's atmosphere almost 600 km above Earth. The Webb is planned to orbit 1.5 million miles away from Earth, around both Earth and Sun. Kepler trails Earth's orbit around the sun.
Communications satellites normally operate at 35,000 km above Earth ("geosynchronous orbit;" this is the orbit at which a satellite's orbit follows that of the Earth so that the orbit is "stationary" above Earth). Weather satellites operate at about 1000 to 6000 km above Earth. Spy satellites may operate lower still, in "low earth orbit," where the International Space Station operates, or slightly below that. The Chandra X-ray observatory operates a third of the way to the moon.
Servicing Space Telescopes In Orbit
Space telescopes have to be serviced remotely, in space, or else abandoned. The Hubble, in low-earth orbit, was serviced a number of times, the first when it had lens troubles. They also must initially fit into a rocket, and thus tend to have folding mirrors. (For more about the various space telescopes in operation, see the article at Historic Spacecraft, "Space Telescopes.")

Batteries are filled with different type of chemicals. So, before you embark on reconditioning them learn how to handle them with care. Modern batteries are a lot more atmosphere friendly than they were a few years back, still they contain numerous unsafe and also corrosive elements. If you injure on your own or splash the mix on your skin, look for clinical assistance right away. Wear protective safety glasses, eyeglasses as well as garments when managing these things. Our homes are cluttered with devices as well as devices that run on batteries. Have a look inside your smart phone or laptop or tablet or cam. They all have a battery pack that should be charged regularly to maintain the gadgets running. In time the batteries obtain weak and run out. People wrongly believe that their battery chargers are to blame and buy replacement battery chargers.
The trouble is most likely with the old batteries. As a result of duplicated utilize their capacity to recharge decreases and also eventually they are rarely able to hold fee. This makes it really inconvenient as mobile phones and also tablet computers require regular charging to function. Batteries make life a lot extra simple. You don’t have to trouble with bothersome cords or unpleasant electrical wiring. When charged phones and video cameras could compete hours without need for recharge. With batteries in place power devices no longer need to be controlled around long power cables. Batteries make several tools mobile. You have the liberty to make use of gadgets anywhere you want.
In time the battery life goes down. Refurbishing run-through batteries can make them work longer. They develop a memory result. Recondition helps remove this effect. To do this you have to know the fee ability of the recondition old batteries. When this is properly established it is simple to understand to what extent renovation are required. Without having precise dimension of charge ability you won’t have a concept how much improvement to make. When you make an initiative to recondition batteries as well as recycle them you are making favorable payment to the setting due to the fact that batteries happen to one of the most contaminating things in the world as they include numerous toxic and also dangerous chemicals in them. Likewise, you will certainly conserve loan by recondition old batteries. Take for circumstances cars and truck as well as scooter batteries, batteries made use of in solar energy producing devices as well as for power backup. All these batteries set you back a tidy sum. If batteries are refurbished and reused you do not need to pay for brand-new replacements.

The Web eID solution enables the use of Estonian digital documents (ID-card, digital ID, e-Resident’s digital ID, residence permit card, etc.) for secure authentication and signing on the web.
Full service: from research to UI design
Information System Authority
Find it on
Digital societies, made possible by the use of ID cards, are admired by many. However, making the system work smoothly, especially online, can be challenging. The previous web eID solution was complex and caused issues with browser and operating system APIs, resulting in poor user experience and higher support costs. The new Web eID initiative aims to reduce these errors by using various authentication and signing technologies.
The design work focused mainly on the dialogues that appear in the browser for the user. To create a good user experience, we analyzed the various types of end-users and the technical limitations. We developed personas and user-journeys to understand all possible workflows. We created four distinct personas and mapped out alternative scenarios and errors to ensure that users are always guided towards a solution.
The design process prioritized accessibility in all decision-making, following the Web Content Accessibility Guidelines (AA). Both the dark and light themes are supported.
Once the work on dialogues was completed, we also designed a landing page to introduce the technical solution and provide instructions to developers.
The dialogues are presented to the user in all browser activities where ID-card (or equivalent) is required. They guide the user through authentication, signing, possible issues and information.

On Jan. 31, 2019, astronauts on the International Space Station positioned their cameras and readied for a satellite launch. Just as the station was orbiting over the southern border of Brazil, the University of Southern Indiana’s Undergraduate Nano Ionospheric Temperature Explorer (UNITE) CubeSat was released into orbit.
One of 23 CubeSat projects sponsored by NASA’s Undergraduate Student Instrument Project, the team of undergrads from USI have worked since 2016 to plan, design, and build their project for launch into space.
“We are the first spacecraft produced and flown by a public institution in the state of Indiana,” says project mentor and USI Associate Professor of Engineering Dr. Glen Kissel.
In the July/August 2017 story “Spaced Out,” Evansville Living visited the USI students as they were testing components of the miniature satellite. Historically, statistics for academic CubeSats show 45 percent lasting 60 days or longer — as of publication, USI’s UNITE had been in orbit for more than 22 weeks.
“It’s gratifying that we’re able to do this on the 50th anniversary of the first manned lunar landing,” says Kissel. “We really have to be thankful to NASA because they have taken a risk, and for us, it has paid off.”
The student team (ranging from 5 to 10 members through the semesters) not only designed the CubeSat, they also took a big risk in building key elements themselves, including the command board.
While the biggest data gathering point won’t happen until February 2020 when the satellite is at the desired point in the atmosphere, USI’s UNITE currently is gathering internal and solar panel temperature data useful for the CubeSat and scientific communities.
“These undergraduates have shown to NASA that they can do a NASA-quality job,” says Kissel. “It’s working very nicely, and I’m proud of them for that.”

Industrial Computer – A Short Overview
A commercial computer is a computer indicated for commercial objectives, having a kind aspect near to a desktop computer PC as well as with comparable dependability as well as efficiency degrees. Industrial computer systems are generally a lot more expensive than customer computers as well as additionally have higher reliability as well as efficiency degrees. There are 2 major industrial computer categories: supercomputers and grid computing computers. Supercomputers are those with one inner processor and memory pass away per chip. Industrial computers provide significant advantages over desktop computer machines in several ways. For one, they can be far more effective, able to resolve intricate problems faster and also with much less driver treatment. Industrial computing additionally involves a lot more innovative software, which is essential in numerous industries. For example, it would certainly be difficult to run a turret without any machine automation software. Nevertheless, even in making industrial settings, commercial computer systems are much from best. In order for a device to be reliable in its task, it must be attached to a host computer via a network or LAN. Otherwise, the equipments will certainly all perform at the exact same price, leading to a waste of power and also various other sources. To battle this, the majority of producers consist of additional gadgets, such as a key-board and also computer mouse, which allows the machines to communicate with each various other more conveniently as well as specifically. Apart, from waste power, a poor industrial computer would certainly additionally cause a waste of money. In a busy factory floor, for example, it would certainly set you back even more time to go across the aisles of computers and also waste much more materials at the same time. If the business did not have a reliable system, it can easily lose a great deal of cash due to shed production hrs and postponed orders. It is also possible for a commercial computer to accident, leading to shed manufacturing as well as destructive damage to devices. With all these threats in mind, it is necessary that business check their networks closely to avoid these problems. While commercial computer systems are definitely helpful in manufacturing facility automation and also other harsh industrial environments, they do not help a lot when it pertains to temperature level control. Industrial computers count on temperature levels to operate appropriately. Without temperature level control, the equipments will just get too hot and malfunction. Due to this, many manufacturing facilities require air-conditioning to maintain the commercial computer systems at a comfy degree. Or else, the equipment might just break down, leading to huge losses. Computers, on the other hand, are excellent devices for accurate computation. Without them, factories would grind to a halt, creating less goods than required. However although industrial computer systems are extremely useful in making certain precision, there are some downsides also. If a manufacturing mistake occurs, it takes even more time and also resources to correct the issue than it does to in fact make the initial product. Therefore, regardless of the commercial computer system automation, specific business might still find it more affordable to outsource specific jobs to various other firms.


The Luminact team spent the day exploring the Australian International Aerospace and Defence Exposition at Avalon Airport and gaining insight into the latest aerospace and defence technologies. Highlights included the Defence Science and Technology Group (DSTG) showcasing their advanced virtual reality simulation programs, a range of innovative drones, from the RMIT micro 3D printed drone to the massive Northrop Gumman MQ-4C Triton, and an opportunity for our senior consultant Shele to try her hand at flying the Navy’s AS 350BA Squirrel helicopter in the flight simulator.
Avalon 2017 provides a great opportunity to showcase next generation technology, along with services and systems that are on offer to general aviation, as well as defence forces globally. This year the RAAF’s Plan Jericho was a central theme among many exhibitors, made all the more relevant by the imminent arrival of the first two Australian 5th generation F-35A Joint Strike Fighters. Plan Jericho will ensure the RAAF transforms its current capability to leverage the enormous amount of battle-space data available from platforms like the JSF, P-8A Poseidon and EA-18G Growler aircraft into a networked operational environment.

Using IP Address Mobility
To Provide High Availability via NT Clusters
Joseph S. Barrera III
NT Clusters provide high availability services to unmodified clients and unmodified servers using standard network protocols and naming, in particular IP (Internet Protocol) and DNS (Domain Name System). The simplest NT Cluster consists of two NT servers, each capable of providing a service, e.g., a remote file share, so that if one server fails, the other can immediately continue providing the service. Thus to the client, a server failure appears to be an instant reboot of the server. When the low levels of the client software contain retry logic, then the failure can be masked completely.
NT Clusters provide failure transparency via IP Address mobility. Any service provided by the cluster is accessed via a mobile IP address that moves to a surviving node when a previous node fails. The IP address move can be done within four seconds, and is transparent to unmodified and geographically distributed clients. NT Clusters currently use IP mobility to implement highly available web, file, print, and database service, using unmodified NT server applications, for unmodified DOS, Windows and UNIX clients, from anywhere on the planet.
This paper argues that IP mobility is a requirement for high availability to such clients, as the (more natural) alternative of mapping the server’s name to the fixed IP address of the surviving node won’t work. It doesn’t work because the name-to-IP address binding is cached by clients and by DNS itself, and there is no mechanism to update these caches. Thus even after the server name has been bound to the new IP address, clients will continue to believe that the server is down because they will continue to use the IP address for the failed node.
IP mobility is the ability to move an IP address from one machine to another. For IP mobility to be useful, it must be fast (on the order of seconds, not minutes or hours) and scalable (cost independent of number of clients). Fast and scalable IP address mobility is already supported by IP, specifically by IP routing and by the Address Resolution Protocol (ARP) [RFC826] that underlies IP. If a host is on the same physical network as the mobile IP address, it is immediately informed of an IP address move via an ARP broadcast; this allows IP mobility to be fast. If a host is not on the same physical network, then it does not need to be informed of the move; this allows IP mobility to be scalable.
IP routing is what connects different physical IP networks. When a host sends an IP packet to a host on a different network, it actually is sent through a series of gateways, machines connected to two or more networks. Only the last gateway, the one on the same network as the mobile IP address, needs to know the new location of the mobile IP address.
ARP (Address Resolution Protocol)
ARP provides the mapping from an IP address to a MAC (Media Access Control) address (e.g., Ethernet or FDDI address). A host broadcasts an ARP request when it wishes to discover the MAC address for an IP address on the same network. The owner of the IP address responds with an ARP reply containing the corresponding MAC and IP address pair. The original host is then allowed to cache this pair to avoid having to repeat the same ARP request. However, this ARP cache is required to update itself based on the sender’s MAC and IP address of all ARP requests. This requirement ensures that if a host changes its MAC address, its subsequent ARP requests will update the ARP caches of the other hosts on the same network.
When a host reboots, it broadcasts an ARP request for its (normal, non-mobile) IP address. This broadcast serves two purposes. First, it will detect whether the IP address is already in use by some other host (as it should not be), as the other host will respond with an ARP reply. Second, if the host did change its MAC address, the ARP request will update any ARP caches that have an entry for the IP address, replacing the old MAC address with the new. In particular, it will update the ARP cache for any gateway on the network, ensuring that subsequent packets to the IP address sent from outside the network, as well as inside, are ultimately sent to the correct MAC address.
Similarly, when a mobile IP address is moved from one host to another, the new host broadcasts an ARP request containing the IP address and the new host’s MAC address, similarly ensuring that all affected ARP caches are updated with the new MAC address.
NT Clusters use mobile IP addresses in addition to the fixed IP addresses assigned to each node (NT Server) in the cluster. These mobile IP addresses belong to resource groups, groups of dependent resources that the cluster attempts to keep running on one node or another. For example, a resource group might contain a web server, a database server (to handle queries made via the web server), a disk on a shared SCSI string between two nodes of the cluster, a mobile IP address, and a domain name (distinct from that used by any node) bound to the mobile IP address.
A two-node cluster could have two such resource groups, each designated to run on a different node by default. If one of the nodes failed, then the NT Cluster software would detect the failure and move the affected resource group to the remaining node. Once the other resources in the group had been started, the Cluster software would "start" the mobile IP address, triggering the ARP reply broadcasts that would clear any ARP cache entries associating the mobile IP address with the failed node. Any client previously connected to the failed node would now be able to reconnect to the new node.
The NT Cluster software currently takes about four seconds to move an IP address to a new node, corresponding to the four ARP reply broadcasts it does, one a second, before deciding that it is safe to use the address. Future versions of the software could cut this time substantially by recognizing when the IP address was previously in use by a failed node, in which case the new node could start using the IP address immediately.
Note that for IP mobility to work, clients must always refer to the mobile IP addresses and associated names, and never to the actual (fixed) node IP addresses or names. One soon sees that NT Cluster resource groups form "Virtual NT Servers" that take on a life of their own independent of the physical nodes they reside on. For example, one can replace all the physical NT servers, one by one, in an NT cluster without ever stopping the virtual NT servers.
Although IP address mobility does allow NT Clustering to provide high availability, it might seem more natural to change the mapping from domain name to IP address (mobile domain names) instead of IP address to MAC address (mobile IP addresses). However, such an approach does not work, because name-to-IP address mappings are cached in too many places, without any way of updating these caches. This caching reflects the assumption that domain name-to-IP address mappings do not change.
Resolvers Cache Name-to-IP Address Mappings
DNS stores domain name information "in a distributed fashion with local caching to improve performance…. The update process allows updates [of domain name information] to percolate out through the users of the domain system rather than guaranteeing that all copies are simultaneously updated." [RFC1034, pp2-4].
This local caching is done by resolvers, agents that query domain name servers on behalf of users. Such caching is crucial for reducing the cost of name queries for clients, as well as for reducing load on name servers. However, there is no mechanism for name servers to invalidate the name-to-IP-address mappings in these caches. Such mappings are only invalidated when the TTL (time-to-live) associated with them has expired, and these TTLs are usually on the order of days [RFC1034, pp37f]. A TTL short enough to provide timely IP mobility is destined to generate unacceptable load on the corresponding name servers. This is especially true for the most well-known servers (e.g., corporate web sites) for which high availability is particularly important and thus are the best candidates for NT Clustering.
Programs Cache Name-to-IP Address Mappings
Client programs also cache name-to-IP address bindings in a variety of ways. Some programs, when supplied with a domain name, perform the name lookup immediately, and only remember the IP address. Even when such programs contain retry logic, they will be unable to find a host that has resurrected itself with a new IP address. Ping is a trivial example of such a program; a more serious example is the NFS filesystem in, for example, Linux [LINUX].
Other programs will intentionally maintain a private name-to-IP-address cache to avoid the cost of the name lookup. Both the Internet Explorer 3.01 and the Netscape Navigator 3.01 browsers appear to maintain such a cache. Once either has viewed a page on a machine, it will continue to point to the machine’s old IP address even after the machine has reappeared with a new address. This is true even after reloading the current page and even though the machine’s name is clearly part of the URL.
NT Clustering uses IP mobility to providing high availability to unmodified and geographically distributed clients. Fast and scalable IP mobility is provided by IP as-is. The alternative of mapping domain names to different fixed IP address does not work due to the caching of such mappings in clients and DNS itself.

History[ edit ] The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelacedescribing the analytical engine. When building the computer Z1 inKonrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i. Johnson and Frederick P. Buchholz, by writing,  Computer architecture, like other architecture, is the art of determining the needs of the user of a structure and then designing to meet those needs as effectively as possible within economic and technological constraints.
Unlike a regular printer, the plotter can draw continuous point-to-point lines directly from vector graphics files or commands. There are a number of different types of plotters: Plotters were the first type of printer that could print with color and render graphics and full-size engineering drawings.
As a rule, plotters are much more expensive than printers. Hewlett-Packard is the leading vendor of plotters worldwide. An application need not know the names of all the modules or entry points that may be called.
For example, a charting program may be written to work with a variety of plotters, each of which is driven by a different driver package. The application can learn the name of the plotter that is currently installed on the system from another process or by looking it up in a configuration file.
This allows the user of the application to install a new plotter that did not exist at the time the application was written.
It is a device that draws pictures on paper based on commands from a computer. Plotters differ from printers in that they draw lines using a pen. As a result, they can produce continuous lines, whereas printers can only simulate lines by printing a closely spaced series of dots.
Multicolor plotters use different-colored pens to draw different colors.
They are used in engineering applications where precision is mandatory. A plotter works closely with a computer's imaging software to produce a final picture or object.
The first step in using a plotter is to enter the appropriate coordinates for where you want the image to appear on the paper. Modern software allows the user to accomplish this goal very easily by drawing lines and images with the imaging software.
Once the schematics for the image are complete, the computer downloads the coordinates to the plotter, which interprets the code and calculates the most efficient path for the pen and paper.
Newer plotters use one of two programming languages: Early plotters contained two separate pens, one that moved vertically and one that moved horizontally. These plotters were limited in terms of the complexity of the images they could produce as well as the speed at which they could operate.
Modern plotters use a sliding roller, which moves the paper against a stationary pen. A plotter pen is usually a hollow fiber rod with a sharpened end. The ink supply runs through the center of the rod and dispenses through the sharpened tip. The paper moves horizontally and vertically against the pen until the drawing is complete.Developed and Maintained by: Gursharan Singh & Maninder Kaur Browsers Supported: 8+ 4+ 10+ 4+ 4+ Resolution: × In computer engineering, computer architecture is a set of rules and methods that describe the functionality, Johnson had the opportunity to write a proprietary research communication about the Stretch, short time after the brake pedal is sensed or else failure of the brake will occur.

Hello Lazyweb: Home router recommendations?
I just upgraded my home cable modem service to 60Mbps, and I've found that I can get those speeds when I directly connect my laptop to the cable modem - but that's not what a geek does! Through my existing OpenWRT based WRT54GL, I've found that I can only get about 35-40Mbps. So I need to upgrade my router to something that supports probably a GigE WAN port, and some decent throughput, and preferably something that can run OpenWRT. Any suggestions?

Phillip Burgess wrote a tutorial on the Adafruit Learning System about making a personalized NextBus Transit Clock. This project is very similar to the TrainLight project I wrote about recently, but is implemented in a very different way. Phillip’s tutorial uses 7-segment displays and clear labels for the bus route vs the abstract lights in TrainLight, and doesn’t require a proxy server or the Particle Cloud.
The choice to use clear digits for the wait time makes sense when you look at the project photo above. The routes near Phillip’s home run infrequently, with 30-60 minutes between stops. Bus service like this requires a bit more planning to use, so knowing the actual time to the next bus, and the bus after that is useful.
The NextBus Transit Clock uses the ESP8266 WiFi microcontroller on an Adafruit Feather HUZZAH dev board. This is a few dollars cheaper than a Particle Photon, but doesn’t include access to the Particle Cloud. The ESP8266 can be programmed with a Lua script, or with C++ code using the Arduino IDE. The program must be uploaded through a USB cable and I didn’t see any support for uploading through WiFi. The Feather HUZZAH board has support for using a Lipo battery including a charger circuit which is handy for a portable project, but not used in this case. The ESP8266 has limited GPIO pins, but this project only needs two pins to connect to the displays.
The displays used are the Adafruit 0.56” 4-Digit 7-Segment Display with I2C Backpack, which cost between $10-$12 each depending on the LED color. The backpack takes care of refreshing the LEDs, and all the microcontroller has to do to update the time is send I2C messages telling the backpack what segments to turn on. I2C is a good choice for connecting the backpacks as the four displays can be chained together easily using just two pins from the micro.
TrainLight uses a proxy server to convert the NextBus XML data to JSON. The NextBus Transit Clock skips all this and uses an open source TinyXML Library that runs on the ESP8266, so no external server is required. This is impressive as parsing XML is a challenge with limited memory on a microcontroller, but the TinyXML Library with Phillip’s changes takes care of this.
Phillip made it very easy to customize the sketch. There’s a python script you can run on your computer that prompts you for the transit agency, route number, direction, and stop, then outputs code you can paste directly into the Arduino sketch. The only other config you need to do is change the WiFi network name and password to match your network.
￼￼ The tutorial encourages you to customize the enclosure to your needs, but provides all the details of the enclosure Phillip made. The example enclosure uses 3D printing for the back and sides with mounting for the electronics, and laser cut acrylic for the front. The bus route and direction labels were applied to the acrylic using toner transfer paper, which looks nice in the photo and I’m sure looks even better in person.
Suggestions for V2
While Phillip encourages customizing the enclosure to meet your needs, you’re left to figure that out on your own with the reference design requiring a laser printer, 3D printer, and toner transfer kit. I liked the “no tools and low budget” approach that TrainLight took, to make it easy for anyone to reproduce the enclosure.
The NextBus Transit Clock project is a follow-up to another NextBus clock using a Raspberry Pi and a LED matrix. The >$40 spent on four 7-segment backpacks could be used for a 16x32 or 32x32 RGB LED Matrix display instead, which could be used for not only display of transit times, but also more information using text, graphics, or color coding. Phillip designed this clock to be more subdued than his original scrolling matrix transit clock, but a matrix display can be used to present information in a subdued way.
Phillip has a lot of other awesome projects on the Adafruit Learning System, I encourage you to check out what else he has and keep an eye out for his new projects.

We are tackling fundamental problems in computer vision and graphics to achieve a deep understanding of visual information in the world.
Our main challenge in the computer vision domain is divided into two categories: generative and discriminative. Image generation tasks aim to create (or convert) an image reflecting the semantics of the given condition. The representative tasks are image-to-image translation, image colorization, image in-painting and video generation. The discriminative problem tries to compress an image into low-dimensional representation while preserving its essential information. It contains visual representation learning, label propagation, segmentation, and video understanding.


(13WHAM-TV) - You know the iPad, the iPod and the iPhone. The next thing may be the iWatch.
Citing a Chinese tech website, the L.A. Times says Apple is working with Intel on a Bluetooth watch expected to come out by summer.
The Sunday Times says in addition to being able to communicate wirelessly with other devices, the so-called iWatch will send and receive email, texts and Facebook alerts. And later versions may even have a tiny speaker and a microphone.


This lab was fun and relatively easy to do. We didn't have a traditional diode, so we used an LED (the cathode connects to ground and the anode connects to the transistor ) to direct current towards the transistor. We positioned the diode in parallel with the collector and emitter as shown below. We also used a potentiometer to control the speed in which the DC motor operated. In the lab below, we will use an H Bridge to control the direction of the DC motor's operation.
With the H Bridge Lab, I didn't have a switch so we used a button that when held down, would change the direction of the DC motor. We helped to visualize this by putting a piece of tape around the motor's end so that when the change in direction occurs, it is more visible.
We decided to add an additional motor and to add a LED to each in parallel so that when our switch is activated one motor changes direction and its corresponding LED lights up.


Introduction Vaping has become a popular alternative to smoking traditional cigarettes, and with the rise in demand for vape devices, there are various brands and models available in the market. One such brand is the Fume Unlimited Vape, which has gained popularity for its unique features and functionality. In this blog post, we will be discussing how to charge the Fume Unlimited Vape and some tips to ensure its longevity.
Charging your Fume Unlimited Vape is a simple process, but it is essential to follow the correct instructions to avoid any damage to the device or its battery. Here is a step-by-step guide on how to charge your Fume Unlimited Vape:
Step 1: Plug in the USB cable into the charging port on the bottom of the device.
Step 2: Plug the other end of the USB cable into a power source. You can use a wall adapter or a computer USB port to charge the device.
Step 3: The device LED light will indicate that it is charging. When the LED light is red, it means that the device is charging, and when it turns green, it indicates that the device is fully charged.

I had a chance to play with one of the new Retina Macbook Pros in the Apple store in Portland the other day and noticed two things:
- It's beautiful
- Its graphics performance is sluggish
I found point two surprising because I have been watching Intel's roadmap for years and thought Ivy Bridge was just going to slay all expectations. It turns out that pushing 4x the pixels is a daunting task even for the mighty Ivy.
Part of the problem is the way current OSX applications handle their UI processing--the GPU is under-utilized. Mountain Lion (coming later this month) is theoretically going to deal with this, but beta testers have said the improvement is modest at best.
A wonderfully written article by Anand Lal Shimpi states:
There’s simply nothing that can be done at this point - Apple is pushing the limits of the hardware we have available today, far beyond what any other OEM has done. Future iterations of the Retina Display MacBook Pro will have faster hardware with embedded DRAM that will help mitigate this problem.
Sadly, as much as I want that retina display, it looks like I'll be waiting a little longer for the chip makers to catch up with Apple.Go Top


[News article] Entry into the video security market! New company of parking control "QDIS"
관리자 ㅣ 2019-01-02 ㅣ 1229
|QDIS, known as the automotive video interface company, has launched the video security market. As the future business of the company, they will pursue the market with new product development. In order to enter the market, QDIS acquired the ITI, an IP camera developer who was responsible for the development of its automotive rear camera, in 2016, and acquired the VR business centered on IP cameras.|
▲Kim Seong-jin, CEO of QDIS [Photo = Security News]
QDIS acquired ITI by investing in Angel at Hanbat National University. They see that the technical development of artificial intelligence (AI) and recognition algorithms become important, and predicted that the image and sensor parts will be promising. After launching the VR division, QDIS focused on product development investment for two years until the first half of last year. As a result, in the second half of 2018, 360 degree all-around IP camera (omnidirectional IP camera) is used to mass-produce the parking control solution capable of recognizing the 8-sided numbering and recognizing the 12-sided parking space. Starting in September, sales in the public procurement market began to rise.
"The all-round IP camera is a proprietary product that has been patented by QDIS, and will be the future of QDIS for the next decade. In the past two years, focusing on development investments has been like no IP camera sales, Revenue began to be generated by supplying lens modules to INNODEP, an excellent procurement company. VR division sales will surpass the existing automotive division sales from the second half of 2019. "
Kim Sung-jin, CEO of QDIS, said, "I am confident that I have a Omni-Directional IP camera and a parking control solution using it. It is a patented product developed by the technology of the company. Kim was selected as a global IP Star company by the Korea Invention Industry Promotion Association and received support for the patent map, product design and 3D publicity film for the patented technology.
▲ Omni-Directional Camera
QDIS's '12 simultaneous parking control solution' is an intelligent parking control system that utilizes a pano-reflect lens applied to all-directional IP cameras. One camera is used to control up to 12 parking planes without blind spots, and image analysis is carried out to inform them of the availability of parking by a green lamp.
The problem of the parking control solution using fisheye lens is that the edge of the image is distorted due to the nature of the lens, which causes frequent problems in judging whether or not the parking is available. However, QDIS' 12-sided simultaneous parking control solution using a pano-reflet lens is able to construct a stable 12-way parking control solution by dramatically improving the image of the outer frame by applying a patented edge image enhancement design to the lens.
QDIS paid particular attention to the parking control system because it expected the expansion of parking control services to be expanded mainly in luxury apartments. Kim said, "I thought it was very convenient to provide information on the availability of green and red LED in large complex buildings such as department stores and marts. Recently, it has been decided that a parking lot solution is developed in the apartment complex by removing the ground parking lot and constructing a large number of underground parking lots. By developing such a parking control solution, it is possible to secure competitiveness through the parking control as well as convenience of residents "He said.
However, it was difficult to develop the product. They need to develop a solution that can reduce the errors and determine the environment of each parking lot by controlling the camera on one of the 12 sides. It is difficult to create and apply various test environments. Especially, it is difficult to reproduce various types of fire in the development of fire monitoring algorithm.

Solar Panel Repairs
HomeFix Contractors can repair and maintain a wide range of solar panel systems, from small domestic systems to commercial systems containing hundreds of panels.
Solar panel systems are usually very reliable but, as with most things, they can occasionally go wrong. If your solar panel system has stopped generating energy or seems to be generating less energy than usual, one of our expert solar panel engineers can come and assess the system, identify the problem and resolve it as soon as possible to ensure that your Solar Panel System is back up to full working order.
As with most electrical repairs, we suggest you do not attempt to fix solar panel issues problem yourself if you are not qualified to do so. Not only will it be potentially very dangerous, but you could also void the manufactures warranty agreement. We highly recommend getting a professional and trained specialist (such as HomeFix Contractors) to inspect and repair any Solar Panel issues you may have.
Solar Panel Cleaning
Keeping solar panels clean, free from shade and in good working order is vital to solar panel maintenance and performance. Any reduction in the amount of the suns energy your solar panel receives will affect the efficiency and energy produced by the panels. Most commonly used solar panels consist of solar cells covered by a protective glass coating. The dirtier this glass barrier becomes, the more the efficiency of the solar panel will decrease.
More attention should be given to panels situated in dusty or high traffic areas, for example; next to a main road, or near farmland. These solar panels will need cleaning more frequently than others as the dust and dirt build up will be significantly more.


This guide explains how to use the interactive installer program distributed with prokit, the ProteanOS Development Kit, to install ProteanOS on a PC platform.
It is assumed that you have already built and optionally installed prokit.
Make sure you have a computer supported by ProteanOS. If your computer is not supported, you can port ProteanOS to run on it. Currently supported are:
- Lenovo ThinkPad X60, X60s, X60t, T60 (architecture
- Lenovo ThinkPad X200, X200s, X200 Tablet, R400, T400, R500, T500, etc.
- Libiquity Taurinus X200 and Gluglug Libreboot X200 (architecture
Determine the devices from which your computer can boot, for example an internal SATA drive or a USB mass storage device (e.g. a flash drive).
Pick a storage device on which you want to install ProteanOS and connect it to the computer on which you plan to run the installer. You can either connect the device to a different computer (easiest in the case of a USB flash drive, while an HDD or SSD would require a SATA/PATA-to-USB adapter) or run a live GNU/Linux system on the computer on which you plan to install ProteanOS.
Decide which "suite" of ProteanOS you wish to install.

Think of the last time you connected with someone. Perhaps it was via a text message, or a Skype call, or a visit to their home some distance away. In each case, copper was part of the process that enabled the connection.
Throughout the past, present, and future of both transportation and telecommunication, copper has been the common denominator that helps us to connect. Read on to find out how.
1.Copper is the puzzle piece in all modern modes of transport
Nearly all vehicles – whether they’re designed for land, air, or sea transportation – have one thing in common: copper. Not only is copper used in the manufacturing of virtually all forms of modern transportation, it’s also the reason that today we have faster, safer and more reliable ways of travelling than ever before. From electrical motors and wiring, to steering systems and avionics, alloys made from highly conductive, strong and durable copper are usually the first choice in vehicle manufacturing.
We can also thank ultra-strong copper alloys for saving on space and weight in modern vehicles which, in turn, lowers operating costs and improves fuel efficiency across air, land, and sea.
Modern aircraft are generally under pressure to reduce weight and fuel consumption, and so rely on computer-based control systems which use copper wiring to transmit electronic signals.
The cables and conductor wires through which electricity is supplied to trains would not survive the associated wear and tear if they weren’t made of high-strength, corrosion resistant alloys like copper-magnesium.
Copper plays a vital role at sea. It’s present in crucial navigation and communications systems, and is also used to protect ships’ underwater hulls. Copper sheathing spares ships from the corrosive effects of salty seawater, and also prevents marine life from clinging on and slowing ships down. The ancient Greeks originally used plates made of lead to protect ships’ hull, but copper plates proved lighter when first pioneered in the 1700s.
The environmental benefits of fuel efficiency in air, land, and sea vehicles extends to today’s combustion vehicles, as compared to their predecessors that didn’t rely as much on copper.
2.Copper has been a driving force in the automotive industry since its dawn
Even when the first mass-produced automobile was still just a thought in Henry Ford’s head, copper was destined to become a key component. When the Model T Ford was manufactured in 1916, copper was the obvious choice of multi-purpose material for everything from spark plugs to sending control signals.
Copper is still used in cars’ braking systems, gearboxes, and carbon emission controls, and continues to drive comfort, safety and functionality-related innovations in the automobile industry. Copper is so prevalent that luxury cars may contain as many as 28 kilograms of copper, with more basic models weighing in at approximately 15 kilograms of copper. The latter equates to around a kilometre of copper wiring!
While copper’s role in the automobile industry is changing rapidly, the metal is far from falling out of favour. In fact, about three times the amount of copper required for manufacturing fossil fuel-powered cars is needed for producing electric vehicles.
3.Copper is the magic ingredient in electric vehicle manufacturing
Corrosion-resistant and highly ductile copper is a supremely good electric conductor – second only to silver. It is also far more affordable than silver, so is a natural choice of material for manufacturing the vehicles of the future. Copper is used for electric vehicles’ wiring, motors, batteries, as well as the systems that keep them charged and ready to go. The manufacturing of hybrid vehicles’ motors also requires large quantities of copper wiring.
As both traditional and newer automakers speed up the entry of affordable electric vehicles into the global market, demand for copper and other materials used in their manufacturing is increasing. According to estimates, we’ll see 43 percent growth in the market penetration of electric cars by 2035. That’s an increase of around 100 million electric cars! That translates to a 3.6 million tonne spike in demand for copper. Clearly, copper in cars is here to stay.

4.Copper began connecting people before the telephone was even invented
Today, because of copper’s high degree of conductivity, it’s the most widely used element in telecommunications. It all started in the 1820s with the invention of the telegraph, a device that used electrical wiring containing copper to transmit and receive messages over long distances. For those of us who are old enough to remember, it’s the same technology that enabled us to receive telegrams.
Then came the telephone in 1876. But Alexander Graham Bell’s initial invention did not, in fact, utilise copper wire. The very first phone lines (which connected pairs of telephones, enabling two people who owned telephones to talk to one another only) were single grounded wires made of iron or steel. Although some were galvanised for corrosion resistance, corrosion was still a problem.
Noise in the lines was an even bigger problem. The advantages of using copper conducting wire were known, but the technology to make copper wire that was strong enough for overhead use did not exist. After an American named Thomas Doolittle developed a procedure for making hard drawn copper wire in 1877, copper took over the telephone wire market. By 1885, copper had demonstrated its reliability in long distance telephone lines, and soon hard drawn copper wire was being widely produced to keep up with the demand for telephone wires. From there, hard drawn copper wire’s uses were expanded throughout electrical industries.
5.Copper’s evolution from faxes to fibre is a symbol of its future
When faxes took the telecommunications industry by storm in the 1980s, it made demand for copper soar again, as residences and businesses began installing second telephone lines for their fax machines.
A decade or so later, the Internet created even more demand for additional telephone lines, keeping copper in vogue. The advent of wireless and satellite communications – along with the boom in optical fibre use – have affected demand for copper, but it still has an important role to play in keeping the world connected.
Upgrading old-school analogue voice telephony systems to digital requires copper wire and alloy products in the telephones and base stations that facilitate wireless communications. Copper is used in many of the interface devices linked to optical fibre systems. It’s made an appearance in up-and-coming technologies too, including ADSL (Asymmetrical Digital Subscriber Lines) and HDSL (High Digital Subscriber Line) which have the advantage of improving the capacity of existing copper wire to optical fibre without the unnecessary costs involved in switching systems. In short, you’ll find copper in some shape or form in all the newest communications technologies.
Copper will continue to connect us
Copper has shown remarkable versatility in adapting to earth-shaking changes in transportation and telecommunications. It’s puzzling to think that the same material that was integral to the first automobile for the general market is even more indispensable in manufacturing the electric vehicles of the future, and that both the earliest and latest long distance communication devices use the same metal for their components!
But, then, copper cannot be easily pigeonholed. Its strength and ductility is matched only by its conductivity. And, as we go headfirst into the future, its versatility will be matched only by its longevity.

They say puppy love is unconditional. But there are certainly times when it gets put to the test, like when you get awakened every night at 3 am from a dog that needs to go out. As a new owner of a yapping dog, a very sleep-deprived David Hunt created Pi-Rex, a bark-activated door opening project using Raspberry Pi. Although he admits this project isn’t the most secure or a substitute for training your dog, he saw it as an opportunity to experiment with the application to solve a specific dilemma.
Raspberry Pi is a miniature computer. The size of a credit card, the Pi can be used for a wide range of purposes. It features inputs for a keyboard or mouse, along with outputs to connect the device to a monitor or screen.
For this project, the Pi is being used to control several components – the bark detector, a motor driver, and a pulley system.
The bark detector is wired to the input of the Raspberry Pi to detect when your dog barks. The motor driver circuit unlocks the door and the pulley system opens the door.
David started this project by purchasing a DIY audio detection kit. A basic audio detection circuit should suffice. It just needs to be able to pick up the noise and then signal to the GPIO on the Raspberry Pi. Instead of adding a buffer circuit between the audio detector and the GPIO, David simply connected the audio detector directly to the GPIO.
David mentioned that this project could be improved by finding a way to sample audio using the Raspberry Pi in order to compare known barks. For now, the device will simply open when it detects a high enough sound decibel.
Next, you’ll need an actuator to unlock the door. David used a 12V central door lock actuator that only cost a few dollars. This is connected to a makeshift locking system.
The locking system includes an angle bracket and several pieces of metal fused together with the actuator. You’ll need to examine David’s example closely to get a good idea of how to build your own locking system.
The actuator needs to cover two positions – locked and unlocked. When fully extended the locking system will catch the door bolt. When activated, the locking system will allow the door to swing open.
Once you have all the components, you can finally put the entire project together. David mounted all the boards and the Raspberry Pi to a clear acrylic board.
The Raspberry Pi was placed in the center with the audio detector on one side and the motor driver on the other. For wiring, David used Dupont connectors with 2.54mm pitch.
You’ll need to connect the motor driver to the pulley system. The pulley system needs to be able to allow the door to swing open and pull it closed. Before the pulley system can return to the latched position, the door must be closed.
For the code that you will read in the GPIO, you’ll need to follow the specific code provided on David’s post – unless you have programming experience.
Now, Fido can let himself in or out with a bark-activated door opening system using Raspberry Pi. This is just one example of what you can do with the Raspberry Pi. This minicomputer has been used to make handheld arcades, cameras, and dozens of other items. In fact, David has a few other DIY projects on his site that require the use of the Raspberry Pi.
If you want to learn the details of this DIY project, check out the full article from David Hunt on how to make a bark activated door system with Raspberry Pi.


If you have a laptop battery that won’t hold a charge usually it is a good idea to just replace it. But if you want to try a homebrew method to restore it there is some hope.
Put your dead battery in a zip lock back and freeze it for 12 hours. Afterwards, dry it off with a towel and put it in your laptop and charge it fully. Leave your laptop on until it is sufficiently drained and repeat this two more times.
This should help your battery memory so that it will hold a decent charge for awhile.
