I’m having quite a headache on this one. I used to get it done, and just realized now it does not work anymore. Possibly because after some update.
I have OpenVPN running with this config:
client dev tun proto udp remote 184.108.40.206 1194 resolv-retry infinite remote-random nobind tun-mtu 1500 tun-mtu-extra 32 mssfix 1450 persist-key persist-tun ping 15 ping-restart 0 ping-timer-rem reneg-sec 0 comp-lzo no script-security 2 up /etc/openvpn/update-resolv-conf up-restart down /etc/openvpn/update-resolv-conf down-pre dhcp-option DNSSEC allow-downgrade remote-cert-tls server dhcp-option DNS 10.0.0.50 dhcp-option DNS 10.0.0.51 route 10.0.0.50 255.255.255.255 net_gateway route 10.0.0.51 255.255.255.255 net_gateway verb 3 pull fast-io cipher AES-256-CBC auth SHA512 ...
So I have it up and running on tun0. By default, all my traffic is redirected to this interface, no problem.
Except I want some ports, 80 and 443 in particular, to be retirected to eth0 in order to use my regular public IP.
I used to get it done running this script:
ip rule add sport 80 table 128 ip rule add sport 443 table 128 ip route add table 128 to 10.0.0.0/24 dev eth0 ip route add table 128 default via 10.0.0.1
So it used to work like a charm, but now, for some reason, it does not work anymore
ifconfig lookis like this:
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.0.0.50 netmask 255.255.255.0 broadcast 10.0.0.255 inet6 fe80::dea6:32ff:feec:aff6 prefixlen 64 scopeid 0x20<link> inet6 fe80::eb4d:9953:dab1:619f prefixlen 64 scopeid 0x20<link> ether dc:a6:32:ec:af:f6 txqueuelen 1000 (Ethernet) RX packets 50096 bytes 34011045 (34.0 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 49083 bytes 24696341 (24.6 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1000 (Local Loopback) RX packets 7445 bytes 1912768 (1.9 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 7445 bytes 1912768 (1.9 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 tun0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1500 inet 10.8.1.9 netmask 255.255.255.0 destination 10.8.1.9 inet6 fe80::bddd:593b:241f:491f prefixlen 64 scopeid 0x20<link> unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 500 (UNSPEC) RX packets 32682 bytes 25077475 (25.0 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 26904 bytes 4130127 (4.1 MB)
To be clear, a command like
curl -s https://checkip.amazonaws.com used to output my real public IP, now it outputs my VPN public IP.
I”m getting dizzy googling this, tried a lot of things without success but as it used to work I’m suspecting something stupid I must be missing.
Any suggestion would be greatly appreciated

Delta often gets a bad rap amongst my friends, but it’s never been bad about losing your luggage. Now – Delta is rolling out a new real time bag tracking system that is supposed to ensure that more than ever, you both get to the same place at the same time.
Using a similar technology to what is ini Disney’s MagicBand, your Delta luggage will now be tagged with a special Radio Frequency Identification (RFID) tag. This little chip, which is now inside the standard luggage tracking tags, allows Delta to track your bags in real-time using radio waves being emitted. As the bag travel through the system, scanners monitor it’s progress relaying that information both to the Baggage ground crews and right to you, the passenger.
Costing around $50 million to build – the real time checked luggage tracking system not only helps the flow of luggage behind the scenes, but allows you to see where your stuff is through an app on your cell phone. The new high tech system is being rolled out to 84 airports across the country. If you’d like to give it a try on your next Delta flight, go ahead and download the app from Google Play or the the App Store.
Does this new app increase your desire to fly with Delta? Would tracking your luggage as it moves through the airport give you peace of mind, or stress you out even more? Leave a comment and let us know what you think!

Ahh... the uplink port on an ethernet hub
I've had my little hub for years and never looked at the 'uplink' port as anything special. If i had to guess it would this is the one you connect to the router. Turns out it's the most badly named piece of kit ever made. It has nothing to do with uplinking. All it means is that the standard crossover cable can't be used on that port. Once i stopped using it and rebooted all devices in sight the network starts to shine again. If you have to use it use a non-cross cable. Mine's a cheap little hub and these often share port 1 with the uplink port. You can't use both together. So it's one of t'other. Yes, i feel miles behind on networking knowledge now but it's always the small things that you think you're familiar with that you always ignore. Pirsig had the same pain with a little nut on his bike and all of a sudden that little nut or ethernet port suddenly becomes all important.


A Listening Machine
Our brain learns to associate a sound that we hear with the direction of its source, how far away the source is, and what it is. Even if we ignore what we can see, or feel, we are able to localize sources by using only two streams of data, one coming in at each ear. A similar situation arises when we use earphones to listen to a binaural recording. However, any binaural recording cannot produce a surround sound effect for every listener (as detailed below.) My project (ECE 3951/2) aims at resolving this problem through digital signal processing.
Any sound emanating from a source gets modified (or filtered) before it reaches our ears. Our ears, clothes, shoulders, hair, the shape of our heads and the room we are in – all contribute to a filter that modifies a sound before it can be heard. This filtration produces localization cues that are brains have learned to recognize. So, each brain would be looking for cues in the sound it hears, in order to extract information about the source. However, every brain would be searching for different cues, as each individual has a unique phenotype, which affects an audio signal in different ways. We can still determine what these cues could be for someone.
Two mics can be placed inside our ears to record such filtered sound signals (creating a binaural recording) and these signals can be processed to determine the frequency response of the room/body (Head-Related Impulse Response, or HRIR). Adaptive filtration techniques have been successfully used to do this. Such a room response can then be convolved with any recorded sound to add a surround sound effect to music, videogame and movie tracks – but such an effect would work best only for the person who made the binaural recordings in the first place, as each individual’s HRIR is unique.
One way to make virtual surround sound accessible to everyone is to record and process everyone’s HRIR individually. My goal, however, is to implement a neural network that can find patterns in a given set of HRIRs, and can use this information to generate more HRIRs (introducing some randomness into the process). This way, a large number of HRIRs could be generated, that may work for a large set of people. In this way, different HRIRs could be applied to different parts of one sound signal, with the hope that every listener’s brain would be able to recognize at least some of them – resulting in successful localization of a virtual source.
Artificial neural networks that recognize handwriting have been implemented and they work well. In the context of sound, artificial neural networks are also used in voice recognition applications. Therefore, my goal is to learn from these applications and implement them to create a ‘listening machine’ network, which would generate HRIRs for each user to simulate sources at various locations around them. If this works out, some sensors could be added to implement interactive surround sound. This project, if successful, might become an interesting recreational tool!


Building a maintainable bi-directional cross platform protocolJSConfEU/201414-09-2014 Dovbush Pavel, William Lewis
Our talk with William Lewis at JSConfEU/2014
Common web frameworks make the assumption you are going to build against a Restful API, but what if your use case doesn’t fit with the Restful principles. How might you go about systematically designing a protocol between client and server? In this talk we are going to discuss how you can design and build an RPC style protocol and service layer that is flexible and extensible enough to serve multiple cross platform clients and servers, growing with application needs whilst letting developers focus on building features instead of maintaining API boilerplate.


FireAngel’s new connected homes project is tapping into an increasingly connected world to revolutionise fire safety.
The ‘connected home’ is expected to be the next technological revolution. There are already an estimated 10 billion devices globally, which are connected to the internet, and this figure is set to rise to 50 billion by 2020.
But what does the delivery of services over broadband mean for safety in the home? Europe’s leading home safety supplier FireAngel has teamed up with Humberside Fire and Rescue Service to trial connected home technology, installing a number of smoke, carbon monoxide (CO) and cold alarms which feature new and enhanced remote functionality in the homes of those who are most at risk.


With the popularity of cloud and IoT exploding, it was only a matter of time before a company began producing devices that control the items you’ve plugged into the power outlets all throughout your home or office.
Using iHome’s SmartPlug, consumers can take control of the devices they’ve plugged into their power outlets using a mobile app. Let’s say you leave your home and you can’t recall if you turned off the coffee maker. If your coffee maker is plugged into a SmartPlug, you could simply toggle the power off on the port directly from your mobile device.
The SmartPlug by iHome gives users more options than that; Customers can setup profiles that allow them define power settings the for the devices that they use the most in their home. Using the iHome SmartPlug, businesses and consumers will now be able to streamline their energy consumption saving both time and money.
The SmartPlug connects to a cloud service maintained by iHome. The device itself is small, light and durable. Each device has its own individual management key associated with it that helps secure the devices you are managing within your home. The SmartPlug devices directly connect to your in-house WiFi, giving you the ability to manage all of your power settings on the go from any location in the world.
“The SmartPlug is the first in a long line of products [for iHome Control],” Director of Product Development Gary Schultz told TheNextWeb in an interview.
“We created our own cloud infrastructure to handle our iHome Control line of products. Because we have our own cloud now, we can do a lot of cloud-to-cloud partnerships. You can envision in the future the plug interacting with devices from other manufacturers,” added Schultz.
The SmartPlug starts at $39.99 MSRP so if you wanted to install 10 of these in your house, you’re looking at $400 to do so. For some consumers, that’s a small price to pay to gain complete control of the electronic devices connected to wall outlets in your home.

Summit County Alert will begin operating on a new software platform September 30; residents and visitors are encouraged to create or update their accounts and notification settings
Contact:Undersheriff Joel Cochran, Summit County Sheriff’s Office970-423-8911, firstname.lastname@example.org
SUMMIT COUNTY – Summit County government is giving a major facelift to Summit County Alert, the community notification system used by local agencies to provide urgent and public-safety information to residents and visitors. Between Sept. 15 and 30, SC Alert will migrate to the CodeRED software platform, which offers more user-friendly interfaces and a more robust set of notification features and capabilities.
During the transition period, emergency messages will be sent using both the old and new systems. Beginning Oct. 1, all messaging will be delivered on the CodeRED system only.
“We’re really excited about this transition,” Summit County Emergency Management Director Rob Pearce said. “This new system is going to dramatically improve our ability to send targeted, time-critical messages to our community as well as provide mobile app options for the service.”
Local government agencies use SC Alert to send emergency notifications by phone, email and text to keep community members informed of events such as evacuation notices, utility outages, water main breaks, wildfires, floods and hazardous materials spills. SC Alert is also used to communicate non-life-safety information, such as planned road closures, utility repairs and service interruptions.
The new CodeRED platform has the benefit of providing SC Alert notifications via the free CodeRED Mobile Alert app, which can be downloaded from the iTunes Store or Google Play. And app users can even receive location-based emergency notifications from other communities when they travel outside Summit County.
“If you were up in Steamboat Springs for the weekend, and an emergency arose, you’d be able to view notifications from Routt County government,” Summit County Sheriff Jaime FitzSimons said. “And for our visitors who live in another community that utilizes CodeRED, they’ll receive SC Alert messages when they’re here.”
Users may add phone numbers, email addresses and text numbers into their CodeRED accounts, and the system is compatible with TDD/TTY devices for those with hearing impairments.
Summit County is in the process of migrating user account information from the old platform into CodeRED, but not all users are capable of being transferred, because of key technical differences between the old and new systems. So Summit County is urging all current SC Alert users to log in to the new system and create a new managed account. Current SC Alert users will receive invitation and reminder emails from CodeRED this month, beginning the week of Sept. 19.
“We understand that this transition involves a little work on the part of our current 49,204 SC Alert users, but we’re confident that CodeRED is a far better tool through which we can deliver critical information to our community,” Undersheriff Joel Cochran said. “We encourage community members to log in to the new system, make sure their info is up to date and download the mobile app. If Summit County is having a really bad day, SC Alert is among the best ways we have to get in touch with you.”
SC Alert was first launched in 2008 and has since been powered by Cooper Notification, which will soon cease providing and supporting community notification products under the Cooper brand.
To access the new CodeRED system, click the rectangular SC Alert button at the top of the Summit County government website (www.SummitCountyCO.gov). For more information, visit www.SummitCountyCO.gov/SCAlert.

We are using AD9283 expansion module.. Setup: Feeding 3.3V 40MHz square wave; 180mV, 5 MHz single ended sine wave (at high Z) to the Ain+ SMA input, collecting the output samples into a PC and processing the samples in Matlab. Function generator, clock source and data collection system are all high end equipments. Input clock, 5.0V power supply, and the input analog signal are all clean. Observation: Sample values range from about 40 to about 250 (as seen from the Matlab time domain plot), a bit noisy.. When we compute SINAD using Matlab function, we get about 35 dB. However we expect about 47-48 dB of SINAD as per the data sheet of AD9283.. 13-14 dB is a huge degradation. Appreciate any suggestions/ thoughts.

The printer connects to the jetpack and prints a success page, but the jetpack doesn't show it as a connected device and I'm unable to ping or connect in the network. When I switch back to my mobile hotspot it works and prints as it should. I was under the impression these were using the same build and should work pretty much the same as eachother. Can't understand why my phone would work find but the jetpack does not.
When you switch the network connection from the mobile hotspot to the Jetpack the IP Address of the printer is changing. You need to uninstall and reinstall on your S7 after you hook up the printer to the Jetpack. Check the new IP Address of the printer when it is connected to the Jetpack, not the old one.
IF you are positive you are checking the correct IP Address of the printer while connected to the Jetpack then the next possible issue is a feature commonly called "Wireless Isolation". This feature limits all connected devices to access the internet only and doesn't allow them to talk to other devices on the Jetpack. You can search the User Guide of your Jetpack to see if it supports this feature and disable it to work around the problem.
See page 62 of the User Guide for the Guest Network feature:

Pentagon plans for 'doomsday' artillery shell containing an electromagnetic pulse weapon powerful enough to cripple an entire city's electronics revealed
Daily Mail U.K. / January 18, 2017
- Pentagon is calling for a 'non-kinetic effects' weapon for 155mm projectiles
- Would be an electromagnetic pulse artillery shell that could wipe out electronics
- It would destroy electronic infrastructure without physically causing damage
The US Department of Defense is developing a powerful new weapon that could cripple an entire city without directly hurting anyone.
A recent solicitation from the Pentagon calls for a non-explosive electromagnetic pulse artillery shell capable of wiping out ‘a wide range of electronics, critical infrastructure, and computer-based systems.’
The non-kinetic system would first be incorporated into a 155mm projectile and later scaled down to enable the use of multiple shells, allowing for devastating electronic attacks that are delivered by standard munition but cause no physical damage.
According to the solicitation, the weapon will be designed to be cost-effective and precise, launching the non-kinetic effects (NKE) from a close range to limit the affected area.
Essentially, such a weapon would render the target’s entire electronic infrastructure useless.
The DoD will first develop a prototype weapon for the 155mm projectile, with the ultimate plan to create a ‘ruggedized, hardened electronics subsystem.’
During the development process, the report says they’ll also be exploring and demonstrating different ways to carry out non-kinetic attacks, and testing the system’s capabilities in the field.
‘Extensive use of wireless RF networking for critical infrastructure and communications systems provides an alternative attack vector for the neutralization of an adversary’s underlying industrial, civil, and communications infrastructure without the destruction of the hardware associated with those systems,’ the solicitation states.
‘Advances in munitions-based microelectronics and power technologies make possible the implementation of non-kinetic cyber and electromagnetic ‘or electronic warfare (EW)’ attacks that could be delivered via artillery launched munitions.
‘The precision delivery of the non-kinetic effects (NKE) electronics payload close to the target allows low power operation which limits the geographical extent of impacted systems, and reduces the overall impact on the electromagnetic spectrum.’
The new development comes more than a year after a report warned that America is falling behind in the development of critical electromagnetic weapons that some say could wipe out 90 percent of its population.
The Center for Strategic and Budgetary Assessments says the technology is 'one of the most critical operational domains in modern warfare.' However, it concluded 'unfortunately, 'failed to keep pace' is an appropriate description of the Department of Defense's (DoD) investments in EMS warfare capabilities over the last generation.
The report, 'Winning the Airwaves: Regaining America's Dominance in the Electromagnetic Spectrum', added the technology will become as revolutionary as smartphones.
'In the same way that smartphones and the Internet are redefining how the world shares, shops, learns, and works, the development, and fielding of advanced sensors and networking technologies will enable militaries to gain significant new advantages over competitors that fail to keep pace,' it says.


two suggestions on the outer door camera
Overall I am satisfied with the outer door camera. Two suggestions:
1) can we remove the ethernet connection port/cable to make the cabling neat? Dont think many people would use it nowadays.
2) can we put the reset button somewhere on the camera itself, instead of having a separate cable? Same as #1 to make the cabling neat.
@luoxin06 Thanks for your precious suggestions.
We will forward it to our R&D department to ameliorate it.

The aim of this paper is to evaluate field values based on electrostatic charge technique of a PM10 mass monitor used for continuous measuring of ambient particulate air pollution. The PM10 mass monitor included electrostatic PM10 mass monitor (EPMM) and wireless monitor systems. In this study, the performance of the EPMM was simultaneously evaluated with a commercially available tapered element oscillating microbalance (TEOM) for measurements at ambient condition. The data of the sensor was connected to the internet through a GSM connection to a public cellular network. The monitoring data of ambient PM was collected and compared for both EPMM and TEOM by measuring at Chiang Mai City Hall during May 1st e 31st, 2015. The two different instruments showed good results that were highly correlated. The comparison between the EPMM and TEOM data values resulted in R2 of 0.8352 and 0.9697, and a slope of 0.8401 and 0.9087 for 1-h and 24-h, respectively. In addition, it was found that the relative humidity played an important role in PM10 mass concentration and its electrical properties of the EPMM. Particularly the EPMM proved its advantages in measuring and detecting PM10 particulate air pollution for mass concentrations in the range from 0 to 500 mg/m3 .


You’ve probably heard of the Avast blocking router feature inside the news recently. However , will possibly not be sure just what it does or perhaps why it really is blocked. For anybody who is wondering for anyone who is at risk of getting the network affected, you should take the time to read the information down below. The following is a brief description of AVAST obstructing router. Hopefully, it will help is made a decision about whether to use this kind of feature or not.
Usually, your router connects to the DNS server that is provided by your internet connection. If your ISP’s DNS server isn’t shown, https://routerservicesca.com/what-should-you-know-about-avast-hardware-assisted-virtualization/ you must check the DNS settings. Changing this establishing can allow online hackers to refocus web traffic, accumulate personal information, or download malware. To check the DNS configurations of your router, go to it is admin menu and click on the “DNS” option. Delete any kind of suspicious DNS servers which can be there.
If perhaps Avast is certainly preventing you from using the DNS storage space on your router, you need to make some changes. Generally, you may use free DNS servers. If your ISP’s DNS server is usually outdated, you should utilize the general public DNS servers. This will ensure that your network connection won’t be infected. The next step is to configure the DNS adjustments manually. Using a no cost DNS machine will help you cured this issue.


Mobile Spy cell phone monitoring software monitors your child or employee's smartphone activity on Android-based smartphones and tablets. Then install the tamper-proof app directly onto the compatible smartphone you own and wish to. Mobile Spy Android Monitoring App monitors Android phone activity. This monitoring software tracks SMS, GPS locations, Photos and more.
For example, you can query all paired devices and get the name and MAC address of each device, as the following code snippet demonstrates:. To initiate a connection with a Bluetooth device, all that's needed from the associated BluetoothDevice object is the MAC address, which you retrieve by calling getAddress.
You can learn more about creating a connection in the section about Connecting Devices. Performing device discovery consumes a lot of the Bluetooth adapter's resources. After you have found a device to connect to, be certain that you stop discovery with cancelDiscovery before attempting a connection. Also, you shouldn't perform discovery while connected to a device because the discovery process significantly reduces the bandwidth available for any existing connections. To start discovering devices, simply call startDiscovery.
The process is asynchronous and returns a boolean value indicating whether discovery has successfully started. The discovery process usually involves an inquiry scan of about 12 seconds, followed by a page scan of each device found to retrieve its Bluetooth name. The system broadcasts this intent for each device. The following code snippet shows how you can register to handle the broadcast when devices are discovered:. This issues a request to enable the system's discoverable mode without having to navigate to the Settings app, which would stop your own app.
By default, the device becomes discoverable for seconds, or 2 minutes. This configuration is insecure and therefore highly discouraged. A dialog is displayed, requesting the user's permission to make the device discoverable, as shown in Figure 2. If the user responds "Yes," then the device becomes discoverable for the specified amount of time. Your activity then receives a call to the onActivityResult callback, with the result code equal to the duration that the device is discoverable.
If Bluetooth has not been enabled on the device, then making the device discoverable automatically enables Bluetooth. The device silently remains in discoverable mode for the allotted time. Possible values for each extra are as follows:. If you are initiating the connection to a remote device, you don't need to enable device discoverability. Enabling discoverability is only necessary when you want your application to host a server socket that accepts incoming connections, as remote devices must be able to discover other devices before initiating connections to those other devices.
In order to create a connection between two devices, you must implement both the server-side and client-side mechanisms because one device must open a server socket, and the other one must initiate the connection using the server device's MAC address. The server device and the client device each obtain the required BluetoothSocket in different ways. The server receives socket information when an incoming connection is accepted.
At this point, each device can obtain input and output streams, and data transfer can begin, which is discussed in the section about Manage a connection. This section describes how to initiate the connection between two devices. One implementation technique is to automatically prepare each device as a server so that each device has a server socket open and listening for connections.
In this case, either device can initiate a connection with the other and become the client. Alternatively, one device can explicitly host the connection and open a server socket on demand, and the other device initiates the connection.
If the two devices have not been previously paired, then the Android framework automatically shows a pairing request notification or dialog to the user during the connection procedure, as shown in Figure 3. Therefore, when your application attempts to connect devices, it doesn't need to be concerned about whether or not the devices are paired. Your RFCOMM connection attempt gets blocked until the user has successfully paired the two devices, and the attempt fails if the user rejects pairing, or if the pairing process fails or times out.
When you want to connect two devices, one must act as a server by holding an open BluetoothServerSocket. The purpose of the server socket is to listen for incoming connection requests and provide a connected BluetoothSocket after a request is accepted. When the BluetoothSocket is acquired from the BluetoothServerSocket , the BluetoothServerSocket can—and should—be discarded, unless you want the device to accept more connections.
In this case, it's used to uniquely identify your application's Bluetooth service. The string is an identifiable name of your service, which the system automatically writes to a new Service Discovery Protocol SDP database entry on the device.
When read byte returns with data from the stream, the data is sent to the main activity using a member Handler from the parent class. When you're done with your BluetoothSocket , always call close. Comprehensive reviews from professionals here at CellSpyApps. Real Time ambient listening is available on Spyera only. Monitor up to three devices.
The name is arbitrary and can simply be your application name. That is, when the client attempts to connect with this device, it carries a UUID that uniquely identifies the service with which it wants to connect. These UUIDs must match in order for the connection to be accepted. This is a blocking call. It returns when either a connection has been accepted or an exception has occurred.
A connection is accepted only when a remote device has sent a connection request containing a UUID that matches the one registered with this listening server socket. When successful, accept returns a connected BluetoothSocket. This method call releases the server socket and all its resources, but doesn't close the connected BluetoothSocket that's been returned by accept.
Because the accept call is a blocking call, it should not be executed in the main activity UI thread so that your application can still respond to other user interactions.
It usually makes sense to do all work that involves a BluetoothServerSocket or BluetoothSocket in a new thread managed by your application. To abort a blocked call such as accept , call close on the BluetoothServerSocket or BluetoothSocket from another thread. In this example, only one incoming connection is desired, so as soon as a connection is accepted and the BluetoothSocket is acquired, the app passes the acquired BluetoothSocket to a separate thread, closes the BluetoothServerSocket , and breaks out of the loop.
Note that when accept returns the BluetoothSocket , the socket is already connected. Therefore, you shouldn't call connect , as you do from the client side. The app-specific manageMyConnectedSocket method is designed to initiate the thread for transferring data, which is discussed in the section about Manage a Connection.
Usually, you should close your BluetoothServerSocket as soon as you are done listening for incoming connections. In this example, close is called as soon as the BluetoothSocket is acquired. You may also want to provide a public method in your thread that can close the private BluetoothSocket in the event that you need to stop listening on that server socket.
In order to initiate a connection with a remote device that is accepting connections on an open server socket, you must first obtain a BluetoothDevice object that represents the remote device. To learn how to create a BluetoothDevice , see Finding Devices. You must then use the BluetoothDevice to acquire a BluetoothSocket and initiate the connection. This method initializes a BluetoothSocket object that allows the client to connect to a BluetoothDevice.
If the lookup is successful and the remote device accepts the connection, it shares the RFCOMM channel to use during the connection, and the connect method returns. If the connection fails, or if the connect method times out after about 12 seconds , then the method throws an IOException.
Because connect is a blocking call, you should always perform this connection procedure in a thread that is separate from the main activity UI thread. You should always call cancelDiscovery to ensure that the device isn't performing device discovery before you call connect. If discovery is in progress, then the connection attempt is significantly slowed, and it's more likely to fail.

There are a myriad of internet service providers that offer different kinds of internet services. There are a variety of DSL, Cable Internet, and Dial Up connection , but satellite internet isn’t as well-known, however, satellite internet is taking the nation by stormdue to its easy setup cost and its availability in remote areas of the globe, satellite internet service providers are now the most popular choice. Satellite internet for consumers is simple to purchase. The satellite internet companies are, not surprising, a few. The majority of the major satellite internet services serve customers with satellite TV and internet who live in rural areas or the suburbs. Businesses are a growing portion of satellite Internet service market. For a long time the satellite ISP providers were viewed as a way to keep the telecoms in business.
The internet has become an essential tool for numerous office tasks (along with being a huge time squanderer) However, if you believed that the advantages of broadband internet was just email and quick research, think again. If you’re trying to send email via the internet rain, sleet, snow, and even dogs that are rabid are welcome obstacles.” E-mail is becoming increasingly insecure due to the apex of spam.
In most cases, providers offer free internet access, however the charges for calls remain in place. Hi-speed internet at the lowest price ever $100 rebate, no installation and service. Beware of deals that appear to provide free hardware, but they’ll charge installation fees instead.
Customers have to select a service by evaluating their rates, availability, customer service and reputation. the decision isn’t always straightforward, due to the numerous providers available and reviews that have conflicting information. Anyone who plans to use the internet should be aware that the internet is not regulated in many cases. Children who use the internet must be conscious of this problem. “They aren’t doing anything to inform customers about the issue.
Spammers were sending out e-mail via the computers of customers at Home to disguise the origin. The majority of spammers conceal their tracks by sending messages via offshore computers and devices which have been contaminated with computer virus. The law hasn’t done much to stop the flow of spam. Four companies -America Online, Earthlink, Yahoo, and Microsoft America Online, Earthlink, Yahoo, and Microsoft have filed lawsuits before federal court in the courts of their states of residence against various groups they believe are spammers. Alongside the defendants identified in the lawsuits the four internet companies sued 220 additional “John Doe” defendants who they claim are sending spam, but cannot be able to determine. The lawsuits rekindled the debate over whether it was the Can-Spam Act was tough enough to tackle a problem that threatens to diminish the effectiveness of e-mails, which is by far the most used everyday use of the internet. The law prohibits the most popular tactics used by spammers, such as the practice of lying about who sent an email and using a false subject line, and stealing computers.

The most popular service was dial-up. However, more and more people are switching to DSL or broadband cable, and even satellite or wireless internet, primarily due to its faster speeds and the convenience. Wireless internet can be offered through wireless modems or wireless card. However, you could also use an at-home wireless modem which does not offer an internet connection that is wireless and mobile service. Wireless internet providers provide users online access without wires, naturally. Access to the internet wirelessly gives users the flexibility to work from anywhere, as they can work from anywhere and anytime they wish. Wireless Internet can also ensure quick exchange and transfer of data. In lieu of having cable line installed inside the home, such as the cable internet requirement or have a telephone line installed for example, DSL requires, satellite internet providers offer wireless internet access via satellite dishes.
In the past, telephone was the only technology that could support internet-based services. As technology improves it is becoming more likely that our media content will be available through the internet. Technology is increasing in popularity and also innovation and we can expect to see a shift in the near future regarding this need. “The technology is brand new, and the response to regulation is also new. The connection between technology and law isn’t always only for the benefit of companies.
A lot of internet providers are holding companies that rent the lines, equipment and other facilities from holding firms. Dial-up internet providers are service providers that permit users to connect to the internet for a cost. A third of internet service providers will cease operations due to the cost of interception.

When PCB production processes need to be refined and improved, several factors need to be considered. One of these factors is PCB manufacturing cost. Most PCB manufacturers quote a quoted price for their products. If you are you looking for more information regarding see page look into our web site. However, there are instances where these quotes fail to account for certain costs which are often hidden in the quote. Some of these costs include quality control costs, which include employee training, materials testing and other aspects not reflected in the quotation.

Apart from the above-mentioned costs, there are other additional costs that have to be accounted for during the PCB manufacturing process. For example, when PCBs are printed in wafer-type PCB layering, the thickness of the wafers is also an important factor to consider during the PCB production process. Typically, printed circuit boards (PCBs) use a minimum thickness of 0.5mm. However, thin PCBs with various thicknesses can be manufactured using a variety of methods including roll laminating, direct thermal roll lamination, solder on substrate and even chemical etching. If a manufacturer wants to manufacture PCBs in greater thickness, he has to purchase the necessary equipment to increase the thickness of the wafer. However, most of the manufacturers do not have the required equipment to add extra thickness to the PCBs.

In addition, there is a need to conduct quality assurance test on the finished products before they are packed. Some of the areas that need to be tested during the PCB manufacturing process are trace resistance, circuit performance, substrate adherence, and moisture resistance. However, some of these tests are interdependent and are difficult to conduct on all PCBs. Therefore, the total cost of producing printed circuit boards using pcb manufacturing process depends upon the test procedures to be performed on each particular PCB.

During the production process, two printed circuit boards are made from the same pcb manufacturing process material using different quantity of materials. The surface of the first PCB is sanded and the top layer is then set as the bottom board. The other PCB is then placed over the first one. It is essential to place the printed circuit boards so that their vertical alignment will be correct. This is because the vertical alignment of printed circuit boards is important for the electronic components to work accordingly. The production of printed circuit boards can be completed within a short period of time.

The pcb manufacturing process enables manufacturers to produce multi-layered printed circuit boards. Some of the multi-layered PCBs are generally used in the electronic devices like digital printers, keyboards, touch screens, cameras, watches, mobile phones, personal digital assistant (PDAs), microphones and other electronic gadgets. Manufacturers can also use pcb prototype maker to design pcb prototype for their products.

The pcb manufacturing process helps manufacturers reduce the cost involved in the production of electronic gadgets. This is because most of the gadgets available in the market today contain multi-layered printed circuit boards which are expensive to create. Through this, pcb manufacturer can easily make low-cost production of customized electronic products. In addition, this pcb manufacturing process enables manufacturers to produce electronic gadgets with uniformity.

The current legislation includes a number of directives on electromagnetic emissions that limit output values in order to avoid interference between different devices and the occurrence of harmful biological effects in the human body.
Human exposure to magnetic fields
Electromagnetic Compatibility is the ability of an apparatus or system to function satisfactorily and without unacceptable electromagnetic disturbances in its surrounding environment, such as other equipment or people working or living nearby.
The practical effect of compliance with the regulations on electromagnetic compatibility is that a device should be insensitive to disturbances generated by other devices at a certain distance (immunity) and the device itself should not generate disturbances that could compromise the functioning of other devices (emission).
We measure electromagnetic fields with duly calibrated instruments in order to certify the performance data of devices operating in a wide range of frequencies (from industrial frequency to microwaves). In addition, at InovaLab we offer the customer our expertise in finding innovative solutions for the evaluation of the biological effects of electromagnetic emissions through numerical calculations during the design of industrial devices or during the adaptation of existing devices to legal directives.
In particular, our work is oriented towards the design of electromagnetic shielding for industrial devices. These are generally high-power systems, for processing materials by electromagnetic induction or by resistance heating.
We also verify electromagnetic pollution produced by industrial or domestic machinery, power lines and radio repeaters.

High data rates demand that the PA navigate this wide range with extremely high speed and accuracy. Both the SIM card and the handset can be tracked.
In many countries, anything older than 3G is no longer even available and almost all new phones being sold feature a predominantly buttonless touchscreen design. And so as mobile phones evolved and were able to give a desktop-like experience for more and more internet-related tasks, HSDPA stepped in.
Being distracted while operating a motor vehicle has been shown to increase the risk of accidents. Today, the mobile phone market is outstripping ownership and use of landline phones in virtually every country on Earth, the steady conversion of more and more of these phones into smarter, more multimedia-friendly devices that work off WiFi, 3G, or 4G networks suggests that the future of mobile development and design will only grow stronger.
SaskTel and its wholly-owned subsidiaries have a workforce of approximately 4, full-time equivalent employees FTEs.
The impact of relying on such outdated technology is huge. It introduces new technologies and covers methodologies to study the performance of frequency allocation schemes.
SaskTel offers a wide range of communications products and services including competitive voice, data, internet, entertainment, security monitoring, messaging, cellular, wireless data and directory services.
The high manufacturing costs were the first hindrance. One reason for their profitability involves the fact that several different Indian companies will pool resources to build out their networks, especially in rural areas, a trend that Kramer said is being imported into Europe.
But the reason behind this is not some out of this world manufacturing cost. Did you develop or utilize primitive phone apps from years ago.
Developing Countries Mobile phone sales in poorer nations skyrocketed between and With coverage ranging from basic concepts to current research, this comprehensive reference contains technical information about all aspects of 3GPP LTE. Now those numbers stand at Mobile development has grown alongside thousands and eventually millions of increasingly-sophisticated mobile applications developed for ever-growing smartphone marketplaces.
As a result, radio spectrum has become an ever-scarcer resource, which mobile operators need to use as efficiently as possible. The thing is, even this year 3G handsets account for less than half the entries in our database though they do generate more than half of all hits. The Nokia was the most notable announcement back in the day, but Sony Ericsson quickly caught up with the Z All parts need to stay balanced or else the evolution is totally pointless.
With this new technology, ten-fold increases over 3G in data transmission ability are coming into the picture, making access to digital media even more robust and further bolstering the demand for media-rich mobile applications. In Egypt, Israel, Japan, Portugal, and Singapore, both handheld and hands-free use of a mobile phone which uses a speakerphone is banned.
With the first 3G networks appearing in Japan at the very beginning of the decadeit took until for the first handsets supporting the new network standard to appear in Europe.
Kenya's M-PESA mobile banking service, for example, allows customers of the mobile phone operator Safaricom to hold cash balances which are recorded on their SIM cards.
New Models New Models As new types of mobile phone are developed and marketed, they will appeal to the segment of the population who, for reasons of business competition, trendiness, or need, are always in the market for the next new thing.
While the phone is turned on, the geographical location of a mobile phone can be determined easily whether it is being used or not using a technique known as multilateration to calculate the differences in time for a signal to travel from the mobile phone to each of several cell towers near the owner of the phone.
Whichever way it happens, there is no question that in the field of mobile phones the result is a massive market. Lennart Hardell and other authors of a meta-analysis of 11 studies from peer-reviewed journals concluded that cell phone usage for at least ten years "approximately doubles the risk of being diagnosed with a brain tumor on the same 'ipsilateral' side of the head as that preferred for cell phone use".
Once midrange mobile phones catch up with the Wireless N connectivity of phones such as the iPhone 4, the Galaxy S and the likes, Wi-Fi will become an even hotter commodity. The high cost of staying in the mobile business, Kramer noted, is leading to a bifurcation throughout the industry, with just two or three carriers and handset makers prospering while the remainder continue to fall behind, their long-term outlooks uncertain.
NFC gives mobile operators a crack at a percentage of the billions of dollars of sales that now flow through the credit card system. At this point, the first pre-smartphone devices began to appear, and the fact that data transmission over these next-generation devices was digital instead of analog allowed them to carry many of the more basic smartphone features that we use as the basis for modern app development.
And, finally, smartphone users experience the frustration of high-power consumption on a daily basis — when their phones run out of battery. On the contrary - 3G radios are pretty cheap to include.
The profits from the minerals finance the bloodiest conflict since the second world war; the war has lasted nearly 20 years and has recently flared up again. These first phones gave basic calling abilities to users and their convenient portable capacities are what established them as widely-used communications devices.
SaskTel today announced it will be adding additional capacity to its 4G wireless network in 17 resort communities across rural Saskatchewan to address the ever-growing.
That demand for video has caused mobile carriers to embrace and encourage “offloading,” in which their users download data not from the carrier’s system, but from the nearest Wi-Fi network. The mobile industry is experiencing explosive growth worldwide, fuelled by almost 7 billion subscribers and an ever-growing demand for data traffic.
Ah, the ever-growing demand for faster network data transfers. Because let's face it, few people actually use video-calling and faster internet connection is. “These upgrades will help bolster our network and add capacity to address the ever-growing demand for wireless data.” See the table below for a full list of towers to be upgraded.
