The unit comes standard with
a remote control which can be used exclusively to run the unit, but most
folks will opt for the $79.00 wireless keyboard (it uses infra-red technology
just like the remote).The modem is connected to a phone line and the video
output to a TV. When you hit the "power" button, either on the remote or
the keyboard, the unit turns itself on and automatically dials an Internet
provider. The very first time this happens, the box dials a WebTV 800 number
and determines the location of the closest WebTV modem bank. It then hangs
up and immediately calls that local number(for our area this is a Toledo

The increasing penetration of stochastic and uncertain inverter-based distributed energy resources (DERs), such as wind and solar PVs, has a considerable influence on the power system dynamics, and the total inertia of the power grid is reduced significantly, causing reliability and resiliency concerns. On the other hand, the power industry is transforming itself from a hierarchical, passive, and sparsely sensed engineering system into a flat, active, and ubiquitously sensed cyber physical system. The emerging multiscale data from phasor measurement units, SCADA, smart meters, weather, and electricity markets offers tremendous opportunities and challenges. Machine learning and big data analytics algorithms and applications for unlocking the potential of big data in smart grid are paid increasingly attention in recent years. This talk will present a set of AI developments for power system operation and controls with DERs, including event detection and disturbance identification, probabilistic transient stability prediction, preventive control considering uncertainties, optimal power flow, as well as some distribution system applications, i.e., topology identification, distribution system state estimation, Vol-VAR control and optimization, microgrid energy management, etc.

The mixed-mode (analog and 12.5 kHz C4FM digital) repeater
The DR-1X can be configured to allow a digital user to transmit in digital and the repeater will convert the digital signal to analog for non-digital users. The repeater is configured via a touchscreen interface on the face of the standard 19″ cabinet-mount unit.
System Fusion is the perfect platform to feed their desire because it brings the right digital solutions to the Amateur VHF & UHF bands. Compared to other Digital modulation methods within FDMA, C4FM is recognized as producing superior audio quality. Equally as important, C4FM provides better reception while you are on the move or receiving challenging weak signals thanks to its better BER (Bit Error Rate) characteristics. C4FM is the principle mode used by professional communication devices in FDMA and is expected to continue to be the leading mode for digital radio communications long into the future.
However, we want you to know that we also strongly believe that conventional analog FM has a number of excellent features that continue to provide substantial advantages over digital modulations, such as low battery consumption and greater distance capability. Therefore, analog FM communications will continue to be the primary method for communication on the VHF & UHF Amateur Radio bands. System Fusion recognizes the continued need for existing conventional analog FM by including a FM Friendly interface; our uniquely flexible DR-1X Repeater that accepts signals from analog FM and FDMA / C4FM digital communication users.
Many Amateur Radio operators have already recognized and enjoyed clear and crisp voice communications provided through C4FM digital communications. It is not just the wonderful audio, though, that makes System Fusion the best Amateur Radio digital communications system. System Fusion is a full 12.5 kHz bandwidth system that includes the ability to transfer reliable high-speed data communications such as text messages, images, and voice memo data – the uses for these impressive features are limited only by your imagination!
System Fusion opens the door to an entirely new era of Digital Communications bringing Amateur Radio communication possibilities that were never possible with other digital solutions in the past.

What is SSH?
SSH stands for Secure Shell (SSH) Protocol that is mainly used to connect to a Linux server remotely. Basically, it gives you the opportunity to access a server/computer over an unsecured network.
How SSH Works?
Client-server architecture is used to implement SSH connections. The remote machine (Server) must be running SSH daemon (The heart of SSH). In SSH, a specific network port (22) is used for connection requests, authentication, and login into shell sessions when the user provides the correct credentials.
How SSH Authenticate Users?
We can use passwords or SSH keys to authenticate the right users to login.
It is not recommended to use passwords to log in, as when the malicious users or bots will keep repeatedly trying to authenticate their accounts, it might potentially lead to security compromises although password logins are encrypted. Therefore, it is less secure compared to SSH Keys.
The SSH keys consist of both public and private cryptographic keys. For the public key, the user can share with anyone freely without any concerns, while the private key must be stored in a secure way and cannot be exposed to anyone.
Steps to authenticate;
- The clients must have an SSH key pair (public and private) on their local computers.
- The local client's public key must be copied to the user's home directory at
~/.ssh/authorized_keyson the remote server.
- When the client connects to the host/server, it will inform the server which public key to use to authenticate.
- The server will validate the public key from
~/.ssh/authorized_keysfile, if it is valid, then it will generate a random string and encrypt it using the public key.
- The server will send the encrypted message to the client to test whether the client has the associated private key.
- After receiving an encrypted message from the server, the client will use the client's private key to decrypt and send the decrypted information back to the server.
- Lastly,the client is able to log into shell sessions when the server determines that the client has the associated private key by validating the decrypted information is correct.

Chameleon Antennas is a site where you can blog, shop, and sign up to receive News Letters in the never ending pursuit of defining whether a Chameleon has antenna or antennae.
Come on by our shop for the best custom built cages by Chameleon Antenna or just for a bag of bugs, and for a discussion about whether Chameleons have Antennas or Antennae.
A) Antennas; In radio an antenna is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver.
B) Antennae; One of a pair of long, slender, segmented appendages on the heads of insects, centipedes, millipedes, and crustaceans. Most antennae are organs of touch, but some are sensitive to odors and other stimuli.
We hope this discussion peaked your interest in this site, and as for the source of confusion between antenna or antennae, it were the Greeks: In consideration that an antenna is a device that sends radio and television signals. The singular noun antenna is just one of the feelers on a bug’s head — a sensory wand the insect waves around to check out its surroundings. The plural of this antenna is antennae. (Those Greeks and their funny words!)


Trailer mounted VMS displays are extremely versatile as they can be easily and quickly deployed at short notice to get information to drivers when and where they need it. The unit is easily transportable and offers the flexibility to warn drivers in advance of temporary events which are likely to impact on traffic such as diversions, accidents, expected congestion, road closures, road-works or contra-flows.
These displays also prove to be invaluable in the effective regulation of traffic during an event, where traffic can become highly congested. This may include effective route signage to direct people to the event or creating diversionary or alternative routes to successfully manage traffic congestion or simply just informing motorists of potential delays or to have tickets ready on arrival.
The VMS display is mounted on a central hydraulic-powered pillar for raising and lowering and is capable of displaying both text and pictograms. Our signs are extremely reliable and user friendly and have a range of remote programming options, thus reducing the need for on-site supervision.
Trailer Mounted VMS Displays may be powered by battery, solar power or mains supply and built-in sensors control the display’s brightness levels to ensure clear, non-dazzling messages. Furthermore, the sign can be fitted with a speed-activated detector which activates the display to flash warning messages to alert the driver.
We can offer a wide range of highway variable message signs suitable for a whole host of traffic management applications, please contact us to discuss your particular requirements in further detail.


The first Pc networks ended up focused Specific-function units for instance SABRE (an airline reservation procedure) and AUTODIN I (a protection command-and-Regulate procedure), the two developed and implemented inside the late 1950s and early nineteen sixties. From the early nineteen sixties Pc suppliers had begun to employ semiconductor technology in commercial merchandise, and the two conventional batch-processing and time-sharing units ended up in place in several large, technologically Highly developed companies. Time-sharing units permitted a pc’s resources to become shared in rapid succession with many people, biking throughout the queue of people so rapidly that the pc appeared devoted to Each individual user’s duties Regardless of the existence of numerous others accessing the procedure “simultaneously.” This led to your notion of sharing Pc resources (known as host computers or simply hosts) above an entire network. Host-to-host interactions ended up envisioned, in conjunction with access to specialised resources (for instance supercomputers and mass storage units) and interactive obtain by distant people to your computational powers of time-sharing units Found elsewhere. These Thoughts ended up 1st recognized in ARPANET, which proven the initial host-to-host network relationship on Oct 29, 1969. It absolutely was developed by the Advanced Study Assignments Company (ARPA) with the U.S. Section of Protection. ARPANET was among the 1st standard-function Pc networks. It connected time-sharing computers at governing administration-supported investigation websites, principally universities in the United States, and it shortly grew to become a vital piece of infrastructure for the pc science investigation community in the United States. Equipment and applications—including the basic mail transfer protocol (SMTP, frequently known as e-mail), for sending small messages, as well as the file transfer protocol (FTP), for longer transmissions—rapidly emerged. In order to realize Price-productive interactive communications amongst computers, which generally communicate Briefly bursts of knowledge, ARPANET utilized the new technology of packet switching. Packet switching takes large messages (or chunks of Pc details) and breaks them into smaller, workable items (often called packets) which will journey independently above any accessible circuit to your concentrate on spot, where the items are reassembled. As a result, unlike regular voice communications, packet switching does not require a solitary focused circuit amongst Each individual set of people. Industrial packet networks ended up launched inside the seventies, but these ended up developed principally to provide effective access to distant computers by focused terminals. Briefly, they replaced very long-distance modem connections by a lot less-highly-priced “virtual” circuits above packet networks. In the United States, Telenet and Tymnet ended up two these packet networks. Neither supported host-to-host communications; inside the seventies this was however the province with the investigation networks, and it would remain so for quite some time. DARPA (Protection Advanced Study Assignments Company; formerly ARPA) supported initiatives for floor-based mostly and satellite-based mostly packet networks. The bottom-based mostly packet radio procedure provided cellular access to computing resources, whilst the packet satellite network connected the United States with quite a few European nations around the world and enabled connections with extensively dispersed and distant locations. While using the introduction of packet radio, connecting a cellular terminal to a pc network grew to become feasible. However, time-sharing units ended up then however much too large, unwieldy, and expensive to become cellular as well as to exist outside the house a local weather-managed computing natural environment. A strong inspiration thus existed to connect the packet radio network to ARPANET so as to enable cellular people with basic terminals to obtain some time-sharing units for which that they had authorization. In the same way, the packet satellite network was used by DARPA to link the United States with satellite terminals serving the United Kingdom, Norway, Germany, and Italy. These terminals, even so, had to be linked to other networks in European nations around the world so as to get to the conclude people. As a result arose the need to join the packet satellite Web, as well as the packet radio Web, with other networks. Basis of the Internet The world wide web resulted from the effort to connect several investigation networks in the United States and Europe. Initially, DARPA proven a software to analyze the interconnection of “heterogeneous networks.” This software, known as Internetting, was according to the recently launched idea of open architecture networking, through which networks with described common interfaces would be interconnected by “gateways.” A Doing work demonstration with the idea was planned. To ensure that the idea to work, a completely new protocol had to be developed and created; without a doubt, a procedure architecture was also needed. In 1974 Vinton Cerf, then at Stanford College in California, and this writer, then at DARPA, collaborated on a paper that 1st explained such a protocol and procedure architecture—specifically, the transmission Regulate protocol (TCP), which enabled different types of equipment on networks all over the environment to route and assemble details packets. TCP, which originally integrated the Internet protocol (IP), a global addressing system that permitted routers to receive details packets for their final spot, formed the TCP/IP common, which was adopted by the U.S. Section of Protection in 1980. From the early nineteen eighties the “open architecture” with the TCP/IP approach was adopted and endorsed by all kinds of other scientists and sooner or later by technologists and businessmen around the world. From the nineteen eighties other U.S. governmental bodies ended up greatly involved with networking, such as the Countrywide Science Basis (NSF), the Section of Electricity, as well as the Countrywide Aeronautics and House Administration (NASA). Even though DARPA had performed a seminal purpose in making a compact-scale Model of the Internet amid its scientists, NSF worked with DARPA to increase access to your entire scientific and academic community and to help make TCP/IP the common in all federally supported investigation networks. In 1985–86 NSF funded the initial 5 supercomputing centres—at Princeton College, the College of Pittsburgh, the College of California, San Diego, the College of Illinois, and Cornell College. During the nineteen eighties NSF also funded the event and operation with the NSFNET, a countrywide “backbone” network to connect these centres. From the late nineteen eighties the network was running at many bits for every 2nd. NSF also funded several nonprofit local and regional networks to connect other people to your NSFNET. A couple of commercial networks also commenced inside the late nineteen eighties; these ended up shortly joined by others, as well as the Industrial World wide web Trade (CIX) was formed to permit transit traffic amongst commercial networks that in any other case would not have already been permitted within the NSFNET backbone. In 1995, following comprehensive evaluation of the specific situation, NSF determined that help with the NSFNET infrastructure was not needed, due to the fact lots of commercial vendors ended up now eager and capable of satisfy the requires with the investigation community, and its help was withdrawn. Meanwhile, NSF had fostered a aggressive collection of commercial World wide web backbones linked to one another by means of so-known as network obtain points (NAPs).


Google announced that it will begin building its third fully privately funded subsea cable that will connect Europe with Africa.
The cable will begin at Lisbon in Portugal and run down the west coast of Africa to connect to South Africa.
Nine branching units will be built into the cable to connect the rest of Africa at a later date. The first stage of development should finish in 2021.
Google and many other large tech companies, such as Facebook and Microsoft, have invested heavily in internet infrastructure projects in order to create more users and steadier connections to increase their bottom line.

Open Transport 1.3 introduces Single Link Multi-homing, a mechanism by which Open Transport can support multiple IP addresses on the same hardware interface. Synonyms for this feature include IP Aliasing, Secondary IP address Support, IP Masquerading, "Multihoming", IP Multinode support. This is useful for sites like Internet Service Providers (ISPs), that want to give each of their clients a distinct IP address, without requiring separate computers for each address. Web server software packages, or server plug-ins that utilize this feature can offer virtual domain support that supports all web browsers. You will need to contact your application developer to see if they are supporting this new feature of Open Transport. This feature is only available with Open Transport 1.3 and later.
You configure a system to use multiple IP addresses as follows:
1. The TCP/IP Control Panel must be set for manual addressing.
2. You create a text file with the required name "IP Secondary Addresses" and put it into the Preferences folder in the System Folder.
Each line of the IP Secondary Addresses file contains a secondary IP address to be used by the system, and an optional subnet mask and router address for the secondary IP address. If there is no subnet mask entry, then a default subnet mask for the IP address class will be used. If there is no router address entry, then the default router associated with the primary address will be used.
Each secondary address entry must be prefixed by "ip=". Each subnet mask entry must be prefixed by "sm=". Each router address entry must be prefixed by "rt=". Lines proceeded by a ; are ignored. An example of the contents of the IP Secondary Addresses file follows.
; 'ip=' for ip address, 'sm=' subnet mask, 'rt=' router address ; Note: no space in 'ip=192.168.22.200' ; ; IP address Subnet Mask router addresses ;----------- ----------- ---------------- ip=192.168.22.200 sm=255.255.255.0 rt=192.168.20.1 ip=192.168.22.201 rt=192.168.20.1 ip=192.168.22.202
The order of the entries is important. The "rt=" entry must follow the "sm=" entry if used.
When Open Transport activates TCP/IP, the primary address will be obtained from the TCP/IP Control Panel setting. Open Transport then looks for the IP Secondary Addresses file in the Preferences folder to determine if additional addresses should also be configured. If there are duplicate IP address entries in the IP Secondary Addresses file, the duplicate addresses will be ignored. When Open Transport binds a TCP/IP connection, if there is an address conflict with either the primary or any secondary addresses with another host, Open Transport will present an error message using a dialog box and unload Open Transport/TCP from memory. The error dialog will display the conflicting IP address, the hardware address of the conflicting machine and note that your TCP/IP network interface has been shut down.
To resolve the conflict, quit all of the TCP/IP applications on both conflicting machines, reconfigure TCP/IP on one of the machines so there is no longer an address conflict, then relaunch your TCP/IP applications.

Bipartisan Legislation to Modernize Rural Call Completion Unanimously Approved by Subcommittee
Important legislation now moves to full committee for consideration
The Energy and Commerce Committee’s Subcommittee on Communications and Technology on Tuesday advanced bipartisan legislation, H.R. 2566, the Improving Rural Call Quality and Reliability Act of 2015, by a unanimous vote. This important legislation, championed by U.S. Rep. Fred Upton, R-St. Joseph, will address persistent problems folks have in Southwest Michigan and across the country with rural call completion issues. These calls completion issues have a negative impact on local small businesses and can pose a threat to public safety when important messages go undelivered.
“It’s never been easier to pick up the phone and dial a number to be in touch with friends and loved ones, no matter where they are in the country. But for those living in rural areas right here in Southwest Michigan and across the country, this connection isn’t always guaranteed,” said Upton. “It’s time we set higher standards for the integrity of our networks, but more importantly for the benefit of folks who need it here at home. I have heard directly from providers in my district as well as local small businesses that this is an issue of great importance and demands action. This bipartisan legislation takes meaningful action to address this problem and I’m proud to support it.”
Sid Shank, Government Policy Coordinator at Acentek, a communications and information technology firm serving primarily rural areas in the Midwest, commented, “I applaud Congressman Upton and his colleagues for tackling this tough issue. Despite amazing advances in technology in recent years, there are still many folks living in rural areas that experience problems with call quality. We know we can do better and today Congress took the first steps to achieving that goal.”
H.R. 2566 requires intermediate telecommunications providers to register with the Federal Communications Commission (FCC) and comply with the service quality standards set by the agency. It would amend the Communications Act of 1934 to ensure the integrity of voice communications and to prevent unjust or unreasonable discrimination among areas of the United States in the delivery of such communications.
The legislation now moves towards consideration of the full committee.

The story behind the image
1999. The Internet had left its infancy and was now heading to take over the world in a storm. Businesses around the world wanted to be a part of this revolution. And there was a second revolution going on: the mobile revolution. And the combination of both – mobile Internet – was set to be the next big thing. I was working at CompuServe in Germany back then which had been acquired by AOL. My task: to define visionary mobile Internet services of the future. It was truly exciting. The stock market was heating up (and as we soon should find out – overheating), and it felt right. We all knew we’d found a gold mine. Or so we thought.
I had arranged a lose partnership with Ericsson, the Swedish mobile phone giant back then, in Germany. They had supplied us with devices for testing and demonstration. I had been working on a mobile maps application demo for the IFA 1999 in Germany (a big consumer electronics trade show back then) and thought it might be a good idea to do a somewhat commercial shot of this. So I placed the Ericsson I888 phone next to the MC 218 on the fincancial section of a newspaper, arranged everything nicely and captured a photo.
The I888 was coined “world phone” because it was a triple band phone that you could use all over the world. The MC 218 was positioned as “mobile companion”. It was just a rebranded facelift of a Psion Seris 5mx palmtop computer with a slightly modified firmware. It could not connect to mobile networks without a mobile phone, so it was not as cool (in reality) as the promotional copy would suggest.
I was proud that I had been able to show how folks of the future (i.e., all of us, today) would be able to use mobile applications, long before Apple launched the iPhone which actually did the trick of taking the mobile Internet to the masses. The MC 218 was a failure for Ericsson, and they st
These were exciting times, and I remember them well. And I am extremely happy that I did this shot in the summer of 1999.

MTN has invested over $120 million in expanding 5G coverage in Nigeria – CFO.
In an exclusive interview with Nairametrics, Mr. Modupe Kadri, the Chief Financial Officer of MTN Nigeria, revealed that the telecommunications giant has made significant strides in expanding 5G coverage in Nigeria. Over the past two years, MTN has invested more than $120 million in bolstering its 5G infrastructure, marking a notable advancement in the country’s connectivity landscape.
Kadri emphasized that these investments have yielded tangible results, with 5G coverage expanding from a mere 3% in 2022 to an impressive 11% by the end of 2023. Despite this progress, Kadri highlighted the urgent need for governmental intervention to address forex challenges and establish fair pricing mechanisms. Such initiatives are essential to incentivize further investments in Nigeria’s telecommunications infrastructure.
Engagement with regulatory bodies is crucial in ensuring that telecom companies can price their services appropriately to sustain ongoing investments. Kadri warned of potential impediments to future infrastructure development if regulatory constraints hinder operators’ ability to justify continued investments. Despite these challenges, MTN remains committed to advancing its network capabilities, exemplified by its proactive acquisition of a 5G license and substantial investment in infrastructure.
5G Adoption and Challenges in Nigeria
Recent data from the Nigerian Communications Commission (NCC) indicates a growing uptake of 5G technology, with connections reaching 2.3 million by December 2023. However, this figure accounts for just 1.04% of the country’s total active telephone subscriptions, which stood at 224.7 million at the end of the year. The slow adoption of 5G can be attributed to various factors, including device limitations and economic constraints stemming from currency devaluation.
While major telecom operators have deployed 5G infrastructure in key urban centers like Lagos, Abuja, and Port Harcourt, the uptake of 5G smartphones remains sluggish among consumers. The devaluation of the Naira has diminished operators’ capacity to invest further in infrastructure, exacerbating the challenge of affordability for many potential subscribers.
- MTN spearheaded the introduction of 5G technology in Nigeria in September 2022, with subsequent launches by Airtel in June 2023 and Mafab Communications later in the same year.
- Despite initial rollout challenges, MTN has expanded its 5G services across multiple cities, with ongoing efforts to extend coverage nationwide.
- Airtel and Mafab Communications have also made strides in deploying 5G networks, albeit facing logistical and market challenges.
By investing heavily in 5G infrastructure, MTN is poised to shape the future of telecommunications in Nigeria, driving innovation and connectivity across the nation. However, collaborative efforts between industry stakeholders and policymakers are essential to overcome existing barriers and realize the full potential of 5G technology in Nigeria’s digital transformation journey.

Modular design compartmentalizes critical functions for redundancy. The Solenoid and Oxygen
electronics (on the SOLO board) can measure and inject oxygen independently of the Primary
Controller handset even in case that the handset or its cable is unplugged or damaged, while the
SOLO board continues to control loop PPO2 until the diver is surfacing.
The control electronics uses the DiveCAN®, a digital communication standard developed by
Shearwater Research Inc. specifically for rebreathers for robust error-checked communications,
when a message is either received correctly or it isn’t received at all. The DiveCAN® is easily
upgradable and expandable.
PPO2 reading output from all three oxygen sensors are electronically separated one from another
as well as the PPO2 reading outputs to the Primary Controller Bus and the Secondary Monitoring
Bus are electronically separated one from another.
The Secondary Monitoring Bus is independent on the Primary Controller Bus and provides backup
PPO2 monitoring in the event of a failure on the Primary Controller.
A fault or short circuit on any sensor or one connected device, it does not affect the remaining
ppO2 readings on the working device.
The Primary Controller handset, the Head-Up Display or NERD2 are connected via the watertight
connectors rated up to 300m depth. The connectors allow flexible connection of the controller
and monitoring devices as well as easy disconnection of the devices for travel, upgrades and repair.

The first type of security camera that came into existence was the analog kind. The analog security cameras could only be used for recording purpose, but they were unable to transmit any live information. The camera footages were also not clear and the only places where they were used were in supermarkets and retail stores.
With the advancements in technology, the analog security cameras were enhanced and a new type of security camera called IP security camera was introduced. With the enhancement in the camera’s features, the IP camera can now connect to the internet and also get clearer and sharper images from the footage. If you are worried about anything like Hikvision security concerns, you can use IP cameras as the concerns are minimal here.
The working of IP-based security camera is not very complex. There is a digital camera that records all the activities happening in front. Then it broadcasts all the video images in the form of digital signals over the Local Area Network (LAN) line. From this LAN line, the video images are transferred to either a server or a computer.
The best part about IP security cameras is that they can be customised based on the requirements. For example, you can flag certain items for future reference or play a particular video image as many times as you want. In addition to this, you can also make the software package of the security camera to analyse all the associated data.
All the IP-based security cameras operate with the help of CCD cameras. These cameras process the signals and create data packets for easy transmission. These small packets of video are transmitted to the Local Area Network through a Cat 5 cable. In earlier security cameras, a coax cable network was used, but this has been replaced in the new cameras so that IP or TCP communication along with the bandwidth can be utilized in a better way.
If the IP cameras are compared to analog cameras, then the former is better because they also offer data mining and retrieve the data in an intelligent manner. If, at any instance, there is a breach of security, the IP cameras can perform data encryption operation so that the images of the video footages are not tampered in any way.
This is how an IP camera operates. If you are looking for an ideal security camera for your business, we recommend you to invest in an IP camera.

(Media release from the Georgia Department of Labor):
As part of the ongoing efforts to modernize and improve efficiency, the Georgia Department of Labor (GDOL) announced strategic improvements to its cloud-based virtual agent – an artificial intelligence (A.I.) solution that improves responsiveness and reduces customer wait times. System upgrades include enhancements to GDOL’s phone system and website chatbot, George A.I.
“Our goal is to become the most responsive agency in state government, which requires us to adapt to the demands and desires of our constituents,” said Commissioner Bruce Thompson. “Claimants that desire to self-navigate will have that option, and those that desire a live respondent deserve that option as well. With this newest introduction of technology, we are rapidly moving toward my goal of delivering incredible service and answers in an expeditious manner.”
Since its launch, this integrated platform has already benefited nearly 1 million Georgians. Key upgrades to the virtual agent include:
- Intelligent call routing to live agents
- The transition of voice services to Cisco Cloud
- Activation of A.I. technologies that can respond to both voice and text
- Multi-language support (English, Spanish, Chinese, Korean, and French)
- Adaptable technology that evolves to serve customer needs
- Self-service tools that resolve FAQs without the need to call an agent, reducing calls and driving traffic to the GDOL website
As part of the recent upgrades, callers can now access GDOL unemployment (UI) services from a single phone number, 877-709-8185. Calls are then routed through a series of A.I.-powered prompts to resolve common UI-related inquiries.
Based on current analytics:
- The combined virtual agent (phone and chatbot) has facilitated approximately 993,141 sessions, accurately routing 97 percent of requests.
- 64,775 customers have used the George A.I. chatbot on the GDOL website to access FAQs. Of these, A.I. technology accurately identified requests 99 percent of the time via chat.
- Over 62,451 virtual agent callers and 4,812 George A.I. chatbot users successfully checked their claim status. Of these, 60 percent effectively used the automated system to check the status of their claim.

Is it possible to have a first network interface on a host only network device?
We are using Vagrant to set up a test environment with several machines running CentOS that must communicate with each other. Our idea was to use host only network interfaces to simulate a network between theses machines. These machines must also communicate with our company network for their provisioning.
The installation scripts for our product assume that there is only one network connection defined in the guest OS, and they define IP Tables rules on eth0. But in Vagrant, the first network interface should be a NAT interface used to control the guest OS using SSH.
What is the best way to configure Vagrant to use another network interface for the SSH connection and define eth0 as a host only network device?
It would be nice if we could avoid using a fixed IP address on our company network.

Technology and mobility increasingly converging
Only a few decades ago, cars primarily used mechanical parts and had limited digital technology built into their systems. The battery was used to start the combustion engine and to power devices like the radio and headlights. Today, the world already looks quite different, with technology playing a major role in modern vehicles — turning cars into control centers with countless digital systems.
From extensive infotainment with navigation systems, internet connectivity, and voice control capabilities, to the many practical driver assistance systems. Today, several kilometres of wires are built into cars, along with numerous control units. In the coming years, this will only increase with autonomous driving requiring even more cameras, sensors and even lasers.
Important partners for digitalization
In order to meet customers’ digital needs and not lose connectivity, many automotive companies are working together with technology companies. This guarantees that innovations are constantly being introduced into the models — in some cases, even exclusively. This is particularly important for infotainment systems, where demand is constantly rising.
Android Auto and Apple CarPlay are important for many users who want to use their smartphones in the car, with streaming services replacing traditional media sources. What’s more, some companies not only bring tech partners on board, but even equip their ranks with experts from the industry.
Technology companies get involved
In recent years, the media have speculated time and again about whether Apple might be working on its own vehicle. However, there is still no concrete evidence of the existence of an “iCar.” But it is confirmed that the Cupertino-based company is working on its own technology for autonomous vehicles. The Alphabet subsidiary Google, on the other hand, introduced its own concept car a long time ago — seeming not to be completely averse to the idea.
In Germany, too, more and more technology companies and suppliers are developing their own technology, mostly in the realm of autonomous vehicles. Electric mobility seems to reduce the barriers to entry. However, the strongest development can probably be seen in China, where the efforts of the corporations are even more extensive.
Tencent invests on a massive scale
In its strategy, Tencent wants to focus on the mobility sector much more in the future. In January 2019, the company confirmed its cooperation with the Guangzhou Automobile Group (GAC). Together with Tencent and other partners, the state-owned vehicle manufacturer set up a joint venture with a starting capital of around $150 million. The cooperation is intended to promote new mobility concepts and digitize existing solutions to a greater extent.
In mid-2019, Tencent also launched a new department under its operations. The new department deals with the topic of “Smart Mobility.” This includes smart infotainment systems, mobile payment, cloud services, and more. Tencent wants to offer its technology to as many different manufacturers as possible.
Alibaba is already in big business
What started out as a B2B platform is now one of the largest technology companies in the world. Alibaba operates numerous subsidiaries, including the B2C platform AliExpress, the payment service AliPay, and the Taobao auction house. Alibaba AI Labs is another one of the companies set up by the industry giant, where the AI it develops communicates with people in the form of the language assistant Tmall Genie. Companies such as Audi, Renault, and Honda use this technology in models for the Chinese market.
Alibaba even built a car with another partner. The RX5 of Shanghai Automotive Industry Corporation (SAIC) was developed in close cooperation with the group. The vehicle, which launched in 2016, contains smart technology that adapts light, music, and target suggestions to the respective user. There are also up to four 360-degree cameras on board to record the journey or for selfies.
Alibaba also invested heavily in Hello TransTech via its subsidiary Ant Financial. The company has been renting bicycles in China for several years, and a carpooling service has been a part of the offer since the beginning of 2019. Hello TransTech’s primary aim is to compete with Didi Chuxing.
Baidu searches for new business sectors
The competition has already shown that it is not enough for internet giants to concentrate purely on digital business. It’s also about developing technology for other industries. Baidu, the Chinese counterpart to Google, is also interested in mobility issues. To this end, the company recently entered into what may be a powerful partnership with Geely. The group brings together several brands, including Lotus and Volvo, which are already well known in the West.
Together, the companies want to develop intelligent vehicles. Here, too, the focus is on artificial intelligence. Together with the commercial vehicle manufacturer King Long, Baidu has already tested the technology. More than 100 buses with “Apollo” technology have already rolled off the assembly line. However, such milestones should only be the beginning for the companies.

I just purchased a certified-pre-owned 2005 CR-V. It has factory-installed XM radio. The radio works fine in all respects except for satellite mode. When I press the CD/XM button, which should toggle between the CD player and satellite mode, nothing happens. Even without an active subscription the radio should go into a satellite demo mode. This is also how you display the radios ID number for a satellite subscription.
Haven't talked to the dealer yet. Anybody know if I am doing something wrong here or is it really a problem with the radio? Anyone else encountered anything similar to this? Thanks.


Automated Drone Service
Our automated drones solution is now integrated with the core Cheetah Logistics Operations Optimization Platform®, Cheetah LOOP®. That means, we can command any size drone to carry any object from one point to another, completely autonomously. The use of drones increases the delivery speed for time sensitive material and adds security at low cost. Their use omits issues with traffic or network environmental concerns. Our system communicates directly with the Cheetah platform, providing full aerial vehicle telemetry in real time. Furthermore, the Cheetah-Air system provides information back to the Cheetah platform with regards to flying parameters including delivery stop arrival and departure, mapping route locations and ETAs etc. With a touch of a button, the dispatcher controls the drone launch which starts its mission and we have 100% accuracy with our take offs and landing location precision. The dynamic nature of the Cheetah routing and logistics platform means we can alter deliveries even after the mission has started and the drone is airborne.
Benefits of using Cheetah Technology
- Fly Straight Shot, No Traffic to Beat
- Pick up and Deliver Point to Point
- Change Delivery Locations En-route
- Create 3D Imaging
