In recent years, we are observing an increase in technological solutions in our homes. So-called “smart” homes are connected with other devices in the house and/or in the garden communicating with each other. A home automation system allows us to control and manage our home remotely, even with the simple use of a smartphone. The use of home automation enables us to customise our homes to suit our lifestyle and routine.
The advantages of smart homes:
A smart home offers many comforts and allows its inhabitants to fully enjoy their lifestyle. With voice commands, you can turn the lights on and off, raise and lower the blinds, receive an updated list of the missing food in your fridge; in short, programme all the appliances and devices in the house and garden, so that your home knows exactly when and how to do what. Just think about going on holiday and being away for an extended period of time. The smart home can simulate your presence by lowering the blinds, turning on the lights and the TV. This system can be programmed at set times, at random times or remotely, making the simulation even more credible. With smart video intercoms you can respond via your mobile phone to a visitor ringing your doorbell, and with smart cameras you can monitor your property and prevent unpleasant situations. Finally, using this technology is very easy thanks to the intuitive design of these devices.
What are the disadvantages of a smart home?
Any device or system connected to the internet may have security issues. There is a real possibility that someone, a hacker for example, could break into your home automation system and violate your privacy. It would not be such a big thing if a stranger controlled your hoover or coffee machine, but it would be a problem if the stranger controlled your alarm system or security cameras. One of the annoyances you may encounter when using smart devices may come from the manufacturers themselves. In fact, when these devices only work thanks to the server of the manufacturing company, it would become a problem if the company went out of business. Another issue to consider is that these smart devices communicate with each other, but sometimes they do not speak the same language. This is due to the fact that there are different communication protocols. In practice, this means that devices will need to be compatible with each other to ensure proper functioning. When devices operate using different protocols, a smart hub is needed, which is basically a central control device that enables dialogue between the various devices. With the advent of voice assistants, smart technology is showing a downward price trend. However, if we wanted to convert our home and all our appliances for smart use, the costs should not be underestimated.

Ribbon cables are usually used as interconnects for internal peripherals in computers, such as hard drives, CD drives, and floppy drives.
Connector Devices would offer you the best quality IC sockets which would prevent damage to ICs caused by soldering IC chips directly to the circuit board. Instead, the more durable IC sockets are soldered to the board and the chip is simply inserted into the socket. IC sockets allow ICs to be inserted and removed easily.IC sockets are important as they enable you to remove or interchange the components without damaging them. This also protects the IC from potential heat damage caused by soldering.
Solar panel connectors are PV (Photovoltaic) connectors that meet MC's standards. MC4 Solar connectors are mainly used in the solar field and are usually used to connect solar panels. With the solar connector, we can push the connectors of adjacent solar panels together by hand, thus quickly constructing a string of panels. To accommodate a broader range of installation environments, we, Connector Devices also offer MC4 Branch connectors..
Mini-DIN is of standards of the Deutsches Institute für Normung, the German standards body. A DIN connector encompasses several types of cables that plug into an interface to connect devices. It has an architecture that is composed of multiple pins that are within a protective circular sheath. We, Connector Devices offer DIN Connectors from 3 to 9 pins.

A USB port is a standard cable connection interface for personal computers and consumer electronics devices. USB stands for Universal Serial Bus, an industry standard for short-distance digital data communications. USB ports allow USB devices to be connected to each other with and transfer digital data over USB cables..
This is the standard connector, found on one end of almost every USB cable. It’s a rectangular connector that only fits in one way. You’ll find several USB-A ports on virtually every desktop computer and laptop. Many TVs, game systems, cars, media players, and other devices have one or more, too..
This is an older connector that’s not used nearly as often nowadays. It’s almost square at one end, and usually plugs into a printer or similar device. Other than these uses, it’s been largely overtaken by the newer standards below..
As the name suggests, this is a smaller connection type that’s good for mobile devices. It’s been largely superseded by micro-USB, but you’ll still find it on some cameras, MP3 players, and other such devices..
This is a tiny connector that’s popular on all kinds of portable devices. Everything from Android phones to external battery packs to Bluetooth headphones uses a micro-USB port. However, some smartphones have moved onto the newer USB-C port..
This is the newest USB standard. Unlike older cables, which usually have USB-A on one end and another type on the other, USB-C can connect two devices that both have USB-C ports. Also different from the above types, it’s reversible. USB-C is slowly being adopted by device manufacturers. Many newer Android phones, like the Samsung Galaxy S9 and Google Pixel devices, use USB-C.
Connector Devices offers PLCC socket of best quality. Plastic Leaded Chip Carrier (PLCC) is a low profile, thin four-wall socket built in a plastic housing used to encase integrated circuit chips. The standard pin spacing of 1.27mm on the PLCC is designed for standard chips which has the same spacing size. PLCC is suitable for use in a variety of device types, including memory, processors, controllers and particularly common for read-only memories as it provides an easily swappable socketed chip. Applications range from consumer products through automotive and aerospace.

Commonly mounted on a PCB or breadboard, DIP switches allow users to quickly preconfigure or toggle an electronic device between a variety of settings or operating modes. DIP switches are an alternative to jumper blocks. Their main advantages are that they are quicker to change and there are no parts to lose.
Connector Devices offers Wafer connectors are very similar to headers. These connectors are polarized which means you can’t plug the mating connector in the wrong way. The male connector is attached to your PCB, while the female is attached to a wire cable. The female connector is crimped on, so no soldering is required. The pin spacing is the same as headers, so they are compatible with each other. Housing are generally made of only plastic parts (some have metal parts), which are assembled with wire and terminal wafer.
Connector Devices offers Zero insertion force (ZIF) is a type of IC socket or electrical connector that requires very little force for insertion. With a ZIF socket, before the IC is inserted, a lever or slider on the side of the socket is moved, pushing all the sprung contacts apart so that the IC can be inserted with very little force - generally the weight of the IC itself is sufficient and no external downward force is required. The lever is then moved back, allowing the contacts to close and grip the pins of the IC.
Wires to board connectors are those connectors which connects a wire to a printed circuit board (PCB), enabling connectivity between circuits. Manufactured for flexibility and reliability, Connector Devices offers wire-to-board connectors in various pins and of different pitches as well as in the straight and right angle form and of the best quality.

Designed to attach and secure the end of an electric cable and the device it's connected to, cable glands provide grounding, insulation, bonding and strain relief. Connector Devices offers cable glands of different materials like nylon and metal and ranging from PG 7 to PG 63.


It would be great if we could have some sort of flexibility with the “Send on Application” emails.
For me, it would be better if we could send a different email based on the application that the candidate completes, instaed of one email being used across the entire portal. We use different applications, and if we could customize our messaging based on that it would be a direction that we would want to go in as the standard “send on application” email isn’t always the appropriate email for every situation, and that’s based on how we use CATS. Ideally I would send a different email for a couple of clients/openings, and I could trigger those based on a specific application being completed.
It would certainly open the door to further customization here on our end in a way that would benefit us greatly.


Ubuntu ufw - setting firewall rules on a per interface basis
Are you needing to configure your server to prevent SSH access to all but your external IP but are still needing SSH connections in your virtual private network? A simple way to harden your server is to configure ufw - Uncomplicated Fire Wall - to manage access to different network adaptors. In this post we show you how.
Which network adaptors?
Step one is to check which Ethernet network adaptors you have installed. Open a new terminal and type the following:
You should see something similar to:
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 162.xx.xxx.xxx netmask 255.255.240.0 broadcast 162.xx.xxx.xxx inet6 xxxx::xxxx:xxx:xxxx:xxxx prefixlen 64 scopeid 0x20<link> ether xx:xx:xx:xx:xx:xx txqueuelen 1000 (Ethernet) RX packets 3620568 bytes 362006705 (362.0 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 4207132 bytes 15241705653 (15.2 GB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.xxx.xxx.xxx netmask 255.255.0.0 broadcast 10.xxx.xxx.xxx inet6 xxxx::xxxx:xxxx:xxxx:xxxx prefixlen 64 scopeid 0x20<link> ether xx:xx:xx:xx:xx:xx txqueuelen 1000 (Ethernet) RX packets 10596 bytes 19622652 (19.6 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 10422 bytes 105107712 (105.1 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 3334690 bytes 2170366969 (2.1 GB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 3334690 bytes 2170366969 (2.1 GB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
This output shows us which adaptor is the external connection and which the internal: the inet address of eth1 starts with a 10 meaning it's internal. And I happen to know the public facing interface of this particular server has an inet address starting 162. So now we can configure ufw appropriately.
Run the following command at the terminal:
sudo ufw allow in on eth0 from [IP addr you are connecting from] to any port 22
Check the rule has been added by running:
sudo ufw status
Now add a rule allowing connections to and from the VPC:
sudo ufw allow in on eth1 to any port 22
Again check the ufw status to ensure your rules have been added.
If it's SSH you are configuring then it's worth ensuring you can still SSH on to your server before closing the terminal you are currently working from. If all is working then your server is now configured.

The new iPhone 14 and iPhone 14 Pro have a ton of new features, including Crash Detection, excellent battery life, and the Dynamic Island, but there’s one feature that hasn’t arrived yet: Emergency SOS via satellite. But it won’t be missing for much longer.
In a press release touting the technology and infrastructure behind the feature, Apple confirms that Emergency SOS via satellite will be arriving “later this month” for customers in the U.S. and Canada. It’s not clear whether it will coincide with the launch of iOS 16.2 or arrive via a separate update.
Apple developed the service in partnership with Globalstar with an investment of $450 million to provide the “critical infrastructure” for the new feature. As Apple explains, Emergency SOS via satellite uses the spectrum in L and S bands designated for mobile satellite services by ITU Radio Regulations. Here’s how it works:
When an iPhone user makes an Emergency SOS via satellite request, the message is received by one of Globalstar’s 24 satellites in low-earth orbit traveling at speeds of approximately 16,000 mph. The satellite then sends the message down to custom ground stations located at key points all over the world.
When a message is received, it’s then routed to emergency services or a relay center with Apple-trained emergency specialists if the closest location is unable to receive texts.
Globalstar executive chairman Jay Monroe calls Emergency SOS via satellite a “generational advancement in satellite communications” thanks to new high-power antennas designed and manufactured specifically for Apple that were installed in all Globalstar worldwide ground stations.
The feature will be free for at least two years for all iPhone 14 users in the U.S. and Canada, including Puerto Rico and the U.S. Virgin Islands. However, Apple says Emergency SOS via satellite isn’t available in Guam or American Samoa, and might not work in places above 62 degrees latitude, such as northern parts of Canada and Alaska.

Can't get internet service at home? Need to stay connected on your next road trip? Check out a Wi-Fi Hot Spot at the Library!
Library cardholders can request a Hotspot at any of our two branches.
Up to 10 devices can connect to the hotspot at one time. Note that connecting many devices may slow down connection speed.
The hotspots are on unlimited data plans managed by the Library. You can use as much data as you desire without deactivation or throttled speeds.
The hotspots gain internet access through Verizon cell towers. If the hotspot has no signal from Verizon, it will not be able to give you internet access.
Check the upper corner of the hotspot and look for signal bars. If no bars are found, the device has no signal. Turn the device off and back on to try to gain internet access. If signal bars do not appear, you may be out of Verizon’s network coverage.
If there are signal bars, the internet may be slow due to the type of signal the hotspot has gained.
The hot spot does not have the ability to forget or disconnect devices from itself. You must manually go into the Wi-Fi settings on your device and "forget" the hotspot in order to disconnect.
Patrons must pay for replacement of any lost or damaged items.
This is due to cell signal irregularities. A normal in-house Wi-Fi router has a direct constant connection to the internet. The hotspots have spikes and drops in signal changing the reliability of internet connection.


Audio Visual cables seem to be the most miss-understood items you can discuss. Some people believe a cable makes no difference to the performance of the system. A large number of people think it’s digital, so it’s perfect, so nothing to ‘worry about’ or “Even Talk About’. So much miss information about cables and their purpose, a minefield. It’s a battle to write anything meaningful without a lot of prejudice bought by the reader. So it’s impossible to have a significant or useful evaluation and discussion.
I have known Cinemike for many years now. How do I know them? I am a customer. I bought equipment (paid real money) from them to do QC on Bluray discs we were producing at the time. I was impressed; I also had some criticism. It showed they were a ‘serious player’ in this market when they took my criticism on board improving the performance, making both of us very happy. I work with professional equipment manufacturers regularly who make equipment for a specific purpose, to do the job correctly. These guys based in a sleepy village outside
So what is a cable? It’s a device to transmit a signal from one piece of equipment to another. Its role is simple its to carry that single as close to the original intent as possible. First of all, there is no such thing as a digital cable if it uses metal for its transmission path. All metal-based cables are analogue and use analogue voltages to simulate digital states. Showing its origins in morse code, and as you have all heard in movies the sounds used to represent dots and dashes, that is an analogue representation of a two-state system. Ultimately, pseudo digital cables such as HDMI are using a similar method. The transmitter is sending two states of voltage, the higher state representing a ‘1’ and the lower voltage representing a ‘0’.
Now that sounds very simple, and yes it is. The issue is, the faster the switching, the higher the frequency travelling down the cable, the longer the length of the cable causes attenuation to the signal. Meaning it will become harder to distinguish between the two states. Added to this, the longer the cable, it will act as an antenna, picking up radio frequencies most of which today are human-made. Mostly mobile phones, 5G will be a nightmare for cable design. This noise will cause spikes making it even harder to identify the two states of voltage. The textbook example of a pure square wave is just that an image in a textbook. By eye on a scope, the signal actual looks like noise, making it hard to identify the two states.
Moden electronics are outstanding and within limits does an excellent job of identifying and distinguishing the two states. A lot of issues come into play once the cable exceeds a certain length. In HDMI 10 meters is the limit, beyond that the single fails. You get green noise artefacts or zits when the error concealment fails; you get nothing. So the design of a cable becomes very critical, very few people making AV cables seem to actually understand the problems and bedazzle the buyer with all sorts of pseudoscience.
Regardless of how well made a metal-based cable is it has many problems. The 1st its length as it will always attenuate the single. The second is the cable will act as a conductor of floating noise from the two pieces of equipment it connects. The third is its a pseudo digital device using analogue voltage levels to represent digital states that are easily corrupted.
An actual pure digital cable (Fibre Optic) two states can be achieved by using light. Light on been a ‘1’ state and light off no light been a ‘0’. An actual digital state, having no ambiguity. Also, as its not an electrical connection, the pieces of equipment cannot ground themselves to each other, so it doesn’t transmit noise between the two devices. With light, the, higher the frequency used does not cause attenuation as it merely just light, no light. The limit is the speed the transmitter can switch, and the receiver can detect.
Projectors are still today the best way to get a big-picture; they also have issues. The main one is they have a massive power supply that regardless of how well it is insulated produces massive amounts of noise. So the best thing would be if you can you galvanically isolate it. Galvanic isolation means there is no direct conduction path connection between two devices.
The perfect method to achieve this is to connect its video feed via a Fibre Optic cable producing a prefect 100% Galvanic isolation. A traditional metal-based HDMI cable cannot accomplish this. One issue a metal-based cable cause is a tremendous amount of noise passes back down the HDMI cable finding its way into the sound system. Digital to Analogue converters are very sensitive to noise. Meaning the purity of the sound produced gets distorted by the noise feeding into them from other sources such as the power supply of the projector. Regardless of how well a metal-based HDMI cable is designed, it won’t stop this. If the cable is engineered well, that will work against you as it will also transmit the noise really well back through the system.
I first tested the original fibre cable that the CineMike version is based on against the best metal-based cable a Cinemike Blue. I am using a DLP cinema projector, why DLP? Well DLP is truly Digital even the light you see on screen is ‘Digital’ it’s never gone back to an analogue stage. All TV’s on the market are analogue, and all projectors other than DLP are also analogue. The final pixel has a Digital to Analogue (DAC) converter to control the voltage of the brightness of the pixel. Which then goes into an amplifier to achieve the intensity which then exaggerates any noise it’s picked up along the way. So it’s easy to see how issues can creep in.
As just discussed DAC’s are very sensitive to noise, so by using a genuinely digital projector, I am removing this stage. I also chose a Xenon based lamp projector as the noise is huge from them, so was interested to see how the backwash of noise into the system would be. I used a Barco DP4K-23B cinema projector, a true 4096 4K cinema projector.
First thing I noticed is the Blue Cable and the Cinemike Fibre cable the picture looked identical. The original fibre cable didn’t which I put down to a clock error issue in the original. The CineMike version has clocks in them that cost about 100 times the price of the original clock and are military-grade. The fact that the Cinemike Fibre and the Blue Cable looked identical was not a surprise. I was happy as this was the correct outcome. Now the more important aspect. The effect on the sound! The projector was now Galvanic isolated from the rest of the system with the fibre cable.
The result was nothing short of revolutionary; the sound had improved on a level I was not expecting. First, it had a delicate purity coupled with an increased dynamic forcefulness. Separation of sounds was truly revealing; detail was improved. Solidness and power in the bass were scary. Coupled with detail in the low end, I had never heard before on this system. It gave an amazing lifelike sound that was so natural & smooth it became addictive to listen too. It’s the whole reason you buy an AV system. It made you feel happy and relaxed, and ultimately you are totally engaged in the sound and vision.
Right Ok, I tried the original Fibre cable now you would think that because it’s Galvanic isolating the system, it would be an improvement? Wrong. Compared to the reference Blue Cable, it was absolutely killing the sound it made the system sound broken small and annoying. It was not making me feel happy; it was doing the opposite it was making me very angry. Not good! So other than for measurements later I thought I couldn’t be bothered to use it in these tests as it had proved to be worthless. It has been such an unpleasant experience reducing a £250,000 worth of equipment to dust.
So on first tests, the CineMike Fibre cable had not only achieved its goal it had surpassed it by a country mile. The picture was correct; all the bits were getting to the screen. It had shown it was truely Galvanic isolating the system from the vast electrical noise from the projection system. Total success so far, so good!
The second test using a Sony Broadcast monitor the Sony BVM-HX310, this is a double modulated LCD based display with full P3 colour space. What I am looking at here is Galvanic isolating the display from system noise. The screen is technically classed as analogue compared to DLP. It may have a digital input; ultimately, the brightness is controlled in an analogue way as the brightness of each pixel is an analogue voltage derived from a DAC. In fact, 26,542,080 of them as it has RGB pixels. So noise getting into the display will affect the image. Its a fact, it can be measured!
First, I tested the reference Blue Cable, yes a good looking image, sharp and defined. I was now even more keen to see how the CineMike Fibre cable would perform. It did! It was another level; the image now looked effortlessly transparent, it looked very similar to the monitor driven by its HD SDI input. In fact, in shadow detail, it looked cleaner, more defined. This is from the galvanic isolation from the rest of the system. I tested the screen contrast ratio between the Blue Cable and the CineMike Fibre. Yes, the system noise was effecting the contrast ratio, it was around 850,000: 1 with the Blue Cable it was closer to spec at 990:000:1 with the Cinemike Fiber. Proving the wash of noise even on a professional display can be affected by floating system tumult. By galvanic isolating the display, we can improve its overall performance. I measured the colour primaries; this is how saturated each primary colour you have can achieve. Yes, the lack of noise had given us 6% more saturation: not a huge amount but enough to make a difference. The system noise was desaturating the image, by isolating it, the pixels could achieve their true potential. What we did measure was very close to Sony’s spec for the monitor. Again a myth is that cables can make things better, no they can’t all a good cable can do is help you achieve as close to 100% of what has been transmitted. If noise is getting into the components, it will affect performance. Only DLP is truly digital and not effected by system noise, unlike LCD/OLED/LED; these are all analogue display technologies.
Again I tested the system audio with the Blue Cable and the CineMike Fiber. With the Blue Cable, it sounded as I expected. When I tried it with the Fibre Cable again a significant improvement not as dramatic as with the projector as the backwash of noise from a xenon 2.5Kw lamp is quite big compared to a monitor. Most notably between the Blue Cable and the CineMike Fibre was the fine dynamics when using the Fibre compared to the Blue Cable. Again the bass had more power and detail when the Fibre cable isolated the system.
I ultimately had to look at performance on a test analyser to see if what I am seeing and hearing can be objectively measured. I believe if you can see it or hear it, you can measure it. The art is getting meaningful measurements; oppositely you get into lies dam lies and statistics territory.
A lot of people say confirmation bias plays a large part in thinking something is better. I did blind test these cables in a random order, yes I could tell every time with the monitor test, both in sound and picture. On DLP you should not be able to tell the difference as its purely modulating the bits to a visual greyscale. Well between the Blue Cable and the Cinemike Fibre, they looked identical. The original Fibre Cable looked dire compared to the metal Blue Cable which as I said should be a physical impossibility that the picture should look degraded. Well, it did! Luckily I have equipment that can measure and isolate the issue. So I know I’m not seeing or hearing things and yes it was clock errors.
Ok, Jitter exhibited on the Blucable is not bad and is about the best I’ve seen for a metal cable added 20 Pico Seconds of TMDS clock jitter +/– 0.1Tbit. An out the box free cable adds about 150 Pico Seconds well within the HDMI spec of 300 Pico Seconds. Some of the more expensive cables I’ve seen which make wild claims introduced some of the worst Jitter. The Eye Diagram is often quoted in tests; I found almost all cables passed this test, and if it failed the cable had visible issues such as dropped frames and picture drop out.
The Blue Cable also had a very low noise characteristic. Which is a credit to its design, the actual cable itself is designed by and made by Jenving technology, founded 35 years ago in Sweeden, sold under the Supra Brand. Then terminated by CineMike using techniques they have perfected with CineMike connectors that are the right impedance. The cable itself is only really good for the picture, and long runs up to 10 meters. Sound over HDMI is another story! Even though we have looked at the sound and sound quilty here, this article/review is only looking at the effect the display cable has by isolation of the display device on the rest of your system.
Now the original Fibre cable was a total mess and measured 390 Pico seconds of noise, and the transmitter injected 690Mv of noise across the spectrum into the system, and the receiver was not far off at 550Mv. Remember an 8bit display has 0.00390625v or 3.9mv as its starting point.10 bits is even more sensitive 0.0009765625v or 0.9Mv steps so 550Mv will flood the DAC causing errors.
The CineMike version with its military-grade clock has just 5 Pico Seconds of Jitter and 0.1Mv of noise across the spectrum so you can see how it would not cause a visual error on a 10 Bit panel.
On a DLP cinema projector, we have no errors caused by noise. Saying that due to the clock in the original fibre cable been so bad, it did cause errors by its poor implementation & noisy components affecting its timing. In turn, caused errors in the data that the DLP projector was using. Making the picture look forced and unnatural due to very high error concealment going on. This is an advert for quilty digital clocks and using the right one for the job. The choice CineMike made paid off with dividends as it produces a close to perfect result. Isn’t that what ‘Digital’ is supposed to be? In reality, Perfect Digital sound and pictures are harder to achieve than its analogue equivalent. The industry, driven mainly by PR companies, has been fooling itself and us for years about the ‘Digital Nirvana’. This has created the likes of CineMike who re-engineer equipment to achieve its true potential. Most equipment is built for a price to get the best it has to be built for a purpose. These guys have created a home cinema market that if you want the best you can have it. The pricing is not outrageous considering each item been rebuilt by hand. I have seen and heard many million Dolar Home Cinema’s that come nowhere close to the results these guys are getting at a fraction of the cost.
So my conclusion is the CineMike HDMI Fiber Cable is a genuinely transparent transport method for picture over short or even long distances up to 300m. Why would you buy this? At €3,000 it is not cheap. Well, if you have a $70,000 projector its a no brainer. Even if you have $20,000 projector, it’s still a must. If you have $500 TV you would be mad; you should go use the money to buy a better TV, the CineMike Blue HDMI would be a perfect choice. This cable is for high-end systems only. No cable should cost more than 20% of your systems components. So you can do the maths if you think your system deserves it.
The CineMike Fibre its excellent value for money! I know of Metal HDMI cables that are three times the price of the CineMike Fibre and a hundred times worse in quality. CineMIke Fibre is genuinely the way to go as it is a genuine digital cable, built correctly. It does what a cable should do complement the system rather than degrading it.
I can’t recommend this cable enough if you have the system for it you would be no brainer must-have. On a high-end system, this actually would be the cheapest and most effective upgrade you can get. Make that call and go for a demo!

Sensitive Operation of Enzyme-based Biodevices by Advanced Signal Processing
Mazurenko, S., Bidmanova, S., Kotlanova, M., Damborsky, J., Prokop, Z.
PLOS ONE 13: e0198913 (2018)
Analytical devices that combine sensitive biological component with a physicochemical detector hold a great potential for various applications, e.g., environmental monitoring, food analysis or medical diagnostics. Continuous efforts to develop inexpensive sensitive biodevices for detecting target substances typically focus on the design of biorecognition elements and their physical implementation, while the methods for processing signals generated by such devices have received far less attention. Here, we present fundamental considerations related to signal processing in biosensor design and investigate how undemanding signal treatment facilitates calibration and operation of enzyme-based biodevices. Our signal treatment approach was thoroughly validated with two model systems: (i) a biodevice for detecting chemical warfare agents and environmental pollutants based on the activity of haloalkane dehalogenase, with the sensitive range for bis(2-chloroethyl) ether of 0.01–0.8 mM and (ii) a biodevice for detecting hazardous pesticides based on the activity of γ-hexachlorocyclohexane dehydrochlorinase with the sensitive range for γ-hexachlorocyclohexane of 0.01–0.3 mM. We demonstrate that the advanced signal processing based on curve fitting enables precise quantification of parameters important for sensitive operation of enzyme-based biodevices, including: (i) automated exclusion of signal regions with substantial noise, (ii) derivation of calibration curves with significantly reduced error, (iii) shortening of the detection time, and (iv) reliable extrapolation of the signal to the initial conditions. The presented simple signal curve fitting supports rational design of optimal system setup by explicit and flexible quantification of its properties and will find a broad use in the development of sensitive and robust biodevices.


There were several outages to report on:
Aug 8 (Friday) - Routing problems were introduced by misconfiguration of a router at UH Hilo. Many UH sites including the MKOCN experienced lost connections between 12:30pm and 2:45pm.
From Aug 28th to September 9th, the UH networks experienced several DoS attacks with similar symptoms. An interface on a core router would stop working after a brief DoS attack and a reboot was needed to reactivate. The problems was solved on September 9th with software patches from Cisco. These outages include:
"Although I am fairly confident that the wireless network at HP will have minimal effect at the summit, I am a lot more worried that inadvertent radio transmission from laptop computers at the summit could become a problem. This could have an insidious manifestation, such as only happening when a certain person observes! The installation of the wifi system at HP will surely encourage people to bring wireless enabled laptops to MK, and therefore could indirectly contribute to unwanted radio interference."
The Working Group agrees with the oversight committee that there is a potential problem with built-in transmitters of observers' laptops. However, the problem will occur with or without wireless implementation at HP because in the very near future, every laptop will be equipped with wireless capability. In the end, the Group decided that a recommendation should be made to the Directors to instruct observers to disable their wireless equipment before going to the summit.
For HP, there was general agreement to wait for the Cisco 802.11g product, which according to Cisco, will soon be announced. If that doesn't happen, field upgradable APs could be deployed with 802.11b radios which could be upgraded to 802.11g when the latter become available.
For the dormitories, Pui Hin is also looking into using dual radios: 802.11a for building-to-building connections and 802.11g for users connections.
Our goal is to negotiate deploying of new technology such as Dense Wavelength Division Multiplexing (DWDM) at MK that will eliminate layers of SONET equipment, making it easier to troubleshoot network failure relating to Verizon services and to lower the cost of connection especially at higher bandwidth. Further, the current SONET infrastructure has a maximum capacity of 11 1/2 DS3s. New equipment must be installed to provide additional bandwidth.
Verizon is currently considering two alternatives, enhanced SONET and DWDM. Enhanced SONET is less expensive to implement at low bandwidth. Along with traditional SONET provisioning such as OC3, DS3, and DS1, enhanced SONET will support ethernet, fast ethernet (FE), gigabit and fractional gigabit ethernet (GE). However, it will not simplify equipment layers for most types of services. DWDM will support many more services such as point-to-point SONET up to OC192 and fiber channel with no Verizon equipment at the customer site. Further, DWDM requires only two fibers to implement a redundant ring while SONET will require four fibers.
To move forward, Verizon will need from us some commitment on future bandwidth needs and how soon we can convert to the new technology. Our costs will involve a non-recurrent charge (NRC). Monthly charge for a GE could be $6k or lower and a FE at $3k, which is the same as what we are paying now for a DS3. However, many of the observatories are separating one or two T1s from their DS3s for voice and video and may not be able to take advantage of the FE at the same cost. Also, it is hard for the observatories to commit to the new services without knowing what the NRC might be.
Pui Hin will continue to work with Verizon on these issues.
This is a follow up of our March meeting when we discussed the need to eliminate the outdoor fiber panel. We were hoping to save some money by having Verizon pull new fibers into the IfA building at the same time they relocate SMA's DS3 to the Research Park. At the meeting, we learned that since SMA's DS3 uses Verizon owned fiber, it will not make any price difference for us to install private fibers at the same time.
However, the Working Group recognizes the need to relocate the fiber distribution panel. Due to budgetary constraints, it would be easier if we were to plan our requirements and costs for implementation for the next fiscal year. So far, Pui Hin has heard only from Gemini.
David Lapsley said:
"Ideally, I would like to transfer the data as fast as possible. I believe 45 Mbps is the current bottleneck limit to Mauna Kea. What would be the maximum rate you would be comfortable for sustained transfers (say 4 hours at a time) over these two days?"
There were no objections to the request and Pui Hin will work with the observatories to determine what will be the best time and maximum bandwidth usage.
Nick Johnson (through email) has the following suggestion for improvement to the topology of the MKOCN.
Pui Hin explained that due to the shortage of fiber within UH-Hilo, it will not be possible to connect each Hilo site with UH-Hilo. However, once new fibers are pulled into the IfA building, it will be possible for each Hilo site to have connections to two different routers in the IfA building where dual routes to UH-Hilo already exist.

Using NiceWatch with proxy server
Article ID: 109 - Updated: May 4, 2010 - Products: - Version: Any - Category: How-To
ProblemNiceWatch does not start if I use proxy server.
NiceWatch is a middleware integration server that consists out of two components. One is the client utility that you use to set up triggers and actions, the other is the actual server that does all the processing and initiates label printing. Both components communicate with each other over the TCP/IP protocol. The port number is 56421.
When using firewalls, make sure the firewall on your computer allows communication between both components. The client component must be able to connect to the server component using TCP/IP port 56421.
When using proxy servers, make sure to allow the computer accessing the local IP address. Usually you have to configure the proxy settings on the computer to be active for internet addresses, not local addresses.
Do the following:
- Open Control Panel -> Internet Properties -> Connections tab -> LAN settings button.
- Disable the option Automatically detect settings.
- Enable the option Bypass proxy server for local addresses.
- If the suggestion with Bypass proxy server... does not help, additionally click on the Advanced button. Then add your subnet block (e.g. 192.168.0.*) to the list of exceptions.
For permanent solution upgrade to NiceLabel software version 5.1.0 or above.

Science has brought about numerous astonishing inventions and discoveries that were once deemed impractical in the Stone Age but are now a reality in our modern world of technology The Ethical Intersection of AI, Neuroscience, and Music in Branding - The fusion of Artificial Intelligence (AI) and neuroscience within the music industry heralds a transformative era in leveraging music to achieve brand objectives. This integration is not just about creating catchy tunes but involves a sophisticated process of understanding and influencing consumer behavior through music. AI, with its vast computational power, can sift through massive… . In the field of communications, in particular, technology has transformed the entire world into a global village. It is now possible to communicate with anyone, regardless of their location, without any difficulties.
Voice over IP (VoIP) is another significant contribution of technology that has provided incredible services and made communications much simpler and more interactive in various ways. In scientific terms, VoIP is a transmission protocol that allows voice traffic to travel over IP communications networks such as the internet or packet-switched networks.
In VoIP, voice traffic is transmitted by converting it into data packets and reassembling them at the receiving end. The primary advantage of this type of data transmission is the ability to send more information using the same bandwidth of the cable. The second reason is the transmission of video and computer Yestel Tablet - Thursday, approaching the End of the Week: Yestel tablet. As the week draws to a close, an unfortunate incident occurred - my son accidentally broke his tablet. In search of a replacement, I turned to Amazon and discovered an exceptional find. Introducing Yestel Tablet: A Remarkable Tablet Brand The tablet I came across was from… data along with the voice.
Thanks to this transmission technology, VoIP offers quite affordable rates for its various services. In certain cases, free calls are even available between VoIP users of the same provider. VoIP also provides a wide range of billing options.
Unlike in the past when a phone was solely used to listen to the voice of the person on the other line, VoIP has introduced various services that have significantly simplified people’s lives in different ways. In addition to high-quality and cost-effective phone calls, VoIP offers video conferencing, which is a crucial tool, especially in the business Navigating the Freelance Landscape: A Guide to Success on Fiverr - In the digital age, the concept of a traditional 9-to-5 job is rapidly evolving, giving way to the rise of freelance professionals.

But you can send us an email and we'll get back to you, asap. Main focus Today, telecommunication infrastructures are usually not properly protected against unexpected events or crisis situations. SAN aimed at resolving several fundamental shortcomings of modern wireless communication systems: The inability of direct communication between the equipment of different users, even when the link quality between them would allow transmission at high bit rates The need to guarantee system performance in complex radio planning The need to connect nodes and base stations in cumbersome fixed infrastructures, and thus the inability of rapid deployment required in many scenarios disasters, military actions, etc.
Approach The SAN project encompassed the whole LTE stack from bottom to top, leading to the integration of all these techniques in a demonstrator and the assessment of its performance: Methods and algorithms for radio interface control, e. Network and upper layer techniques, e. An integrated SAN prototype system, for demonstration and evaluation purposes. Rodoplu and T. Subramanian, H. Gupta and S. Tang, G. Xue and W. In this context, we did an exhaustive survey of unicast MANET routing protocols proposed in the literature. Qualitatively, based on their primary route selection principle, we show that all these protocols could be placed under one of two broad route selection categories: routing based on minimum-weight path and routing based on stability.
In addition to the primary route selection principle, we also identify the underlying routing metric and the routing philosophy proactive, reactive, flat, hierarchical, location-awareness, power-sensitiveness and multipath capability adopted by the different routing protocols.
We believe the survey can be a great source of information for researchers in ad hoc networks. Agarwal, A.

Margot James, the Minister of State for Digital and the Creative Industries, is encouraging local authorities to bid for a share of a £95 million government fund which is devoted to rolling out full-fibre connectivity across the UK.
Full-fibre broadband network by 2033
In 2017, Philip Hammond announced that over £1 billion of funding will be used by the government to drive the next generation of mobile connectivity and roll-out of full-fibre networks.
The government is making progress with the Local Full Fibre Networks (LFFN) Challenge Fund initiative and last month Margot James urged local authorities to get involved:
“We recently set out our ambition for a nationwide full-fibre broadband network by 2033, and initiatives like this will be instrumental in achieving that. We want to hear from any local authority interested in taking part, so we can work closely with them on their plans to help them secure funding.”
The funding will be allocated to local authorities with proposals that align with the following areas:
Rural focus – Local authorities in rural areas of the UK have a strong chance of winning funding as the government wants to improve or introduce Local Full Fibre Networks delivery in hard-to-reach areas of the UK.
5G or Barrier Busting – The government wants to support projects that can tackle “obstacles to the commercial roll-out of fibre and 5G”.
Public Sector Productivity – The Local Full Fibre Networks Investment Panel also wants to support projects that are dedicated to transforming public sector services. Projects should enable public sector organisations to access new cloud-based tools.
Market Development – Projects that deliberately target the development of the full-fibre market in a particular area.
Local Authority Tenders
The government is investing heavily in improving technology across the country. If you are looking to tap into this type of spending, find technology contracts issued by public sector organisations or local authority contract opportunities with Tracker.
Our business intelligence tools can help you to win more local authority tenders, simply request a demo to find out more.

In the 1999 fall beamtime the DSC CsI readout was tested. We found an indication for crosstalk on our ADC channels, which we have used as DSC input.
On the other hand the UVa splitter output is terminated with 50 Ohms; the twisted pair cable impedance is 100 Ohm (as the differential input termination of the ADC). This may cause reflections on these channels.
After our 1999 beamtime a first raw test was made by the input of a NIM pulse of one channel of the twisted pair cable and measuring its crosstalk on the neighbour channels. We could measure up to 15 percent of the original amplitude on the neighbour channels (analog scope, ground connection to the NIM pulser crate). The same test we have made with a sine signal (variation of frequency). Some crosstalk was measureable over the whole cable (8th neighbour). A big portion of this crosstalk was due to the use of the 'spy cards', which we use to split ECL signals. On the other hand we could see a huge noise on all channels.
The crosstalk was measured again without the use of the spy cards with an original CsI signal from channel CsI_02 (all other CsI high voltages are off). Figure 1 and 2 show scope hardcopies of the signals, channel 1 with the original signal, channel 2 shows crosstalk and noise on the neighbur channel. For figuure 1 a twisted pair cable is used, for picture 2 coaxial cables (RG174/U) with the same connector type with flat ribbon cable header.
Figure 1: Crosstalk measurement with twisted pair cables
Figure 2: Crosstalk measurement with coaxial cables
The lower noise and lower crosstalk with 50 Ohm coaxial cables is also visible in our ADC spectra. For this mode a small modification on the ADC board is necessary. Then the ADC operates in 50 Ohm mode for coaxial cables instead of quasi differential input.
Figure 3 and 4 show the ADC spectra for CsI channel 2 with Cosmics. There is no significant difference between the two operation modes of the ADC.
Figure 3: ADC Cosmic spectrum with twisted pair cables
Figure 4: ADC Cosmic spectrum with coaxial cables
By the use of coaxial cables we can reduce the noise by about a factor of 2. Figures 5 and 6 show the noise peaks with twisted pair cables and with coaxial cables.
Figure 5: ADC pedestal peak with twisted pair cables
Figure 6: ADC pedestal peak with coaxial cables
Taking a look on the 2-dimensional Spectrum (Figure 7,8, CsI number versus ADC channels) it is obvious, that there is less noise on more or less all channels. There is more noise on these channels and maybe crosstalk over more or less all channels, because the twisted pair cables are packed very tight.

To visit WAP sites with the browser of your mobile device, if you haven't a flat fee for data transmission, have an added cost to you. You need to establish a data connection with your mobile device and this connection ever have a little cost, but there are a group of emulators of WAP browser that give you the chance to visit this sites without to establish a connection with your mobile device. This browsers allows you to use the Internet connection of your PC to access to this sites without the need to pay an added cost.
You can use the WAP browser of your mobile device or each other of the previously described emulators to visit our mobile devices zone. You can visit our site at the address "juegosenmovil.mobi".
This emulators allows you to browse WAP sites from a WEB page. To use this browsers you only need to provide the WAP address that you want to visit (ex: juegosenmovil.mobi) on a formulary field.
This emulators allows to navigate trough WAP pages from your PC. Generally, this navigators are an application that can show menus to configure how it should works and what is the WAP site to visualize.
This emulators allows to visualize WAP pages with your usual WEB browser. This emulators are installed as add-ons or plug-ins for the WEB browser. For the visualization of the WAP site you only need to introduce the address in the navigation bar like a normal WEB site.
¿What is WAP?
WAP (WIRELESS APPLICATION PROTOCOL) is a protocol specification that allows to the mobile devices to use a wireless connection to access to information and services from Internet. The programming language used for this protocol is the version one of WML and is similar to the HTML for the WEB.
¿What devices uses WAP?
Usually whatever of the mobile devices or devices that allows data connections, supports WAP for the access to Internet.
¿What is WML?
The WML (Wireless Markup Language) is a language similar to the HTML but adapted for the visualization of the pages in the screens of the mobile devices. For use WML is necessary a device with a microbrowser installed.
¿How to browse Internet with a mobile device?
The navigation is similar to the navigation with a PC. It is necessary to start the installed browser in the device and provide the address of the page to visualize, then the device will make a data connection using the WAP protocol and it'll download the WML pages to visualize with the browser.
¿What are the WAP 1.0 features?
The protocols stack of WAP 1.0 is not compatible with the Internet protocols so it is necessary a bridge node who mediates between the WAP client and the content server at Internet. It is a simple set of protocols but with a little possibility of problems about compatibility and security. The language used for the contents is the WML. All of this is provided by the service provider and user doesn't need to manage it.
¿What is WAP 2.0?
The version WAP 2.0 is supported by the new models of mobile devices and changes the version 1 by using for the pages of contents the XHTML-MP (XHTML Mobile Profile), a subset of the XHTML. The contents at WAP 2.0 are more similar to the WEB contents but for mobile devices. This protocol uses for the transport layer the TCP and for the application layer the HTTP. WAP 2.0 solves the security problems of WAP 1.0 and allows the use of a bridge node for improve the service although it is not necessary. In this case as in WAP 1.0 all of this part are technical things related with the phone operator services, and user doesn't need to manage it.
¿What is i-mode?
Is a group of protocols for software applications with a purpose similar to WAP. It allows the user to maintain a connection permanently and the user only need to pay for the data volume transmitted and not for the connection elapsed time. The language used for the pages is the compact HTML (cHTML->iHTML) and not the WML.

Vacuum Tube Technology Could Make Faster Circuits
Once it was invented in the late 1940s, the transistor began to replace the vacuum tube, and led to an amazing range of uses for solid-state devices and the variety of electronic gadgets we have today. Transistors offered savings in both size and energy. But one of the things that vacuum tubes provided was an obstacle free path for unhindered electron flow through the vacuum. "Electrons traveling inside a semiconductor device frequently experience collisions or scattering in the solid-state medium." The problem with vacuum tubes, besides their large size, is that they require high voltages to operate.


Business phone systems are an necessary element of conducting business. It is not enough in order to have a land line. Today’s business world necessitates even more choices and sophistication than ever before. To assure your provider’s long-term viability and proficiency, it is critical that you just work to implement one of the most efficient conceivable system nowadays and continuing to move forward.
The first step in your general effort to further improve business phone systems is usually to choose the accurate PBX carrier. The demand for VoIP is in the root on this requirement. When choosing a PBX provider, you have to take into account both unique attributes of VoIP and its expense to implement. A strong Voice over ip solution is not going to ensure that you own a high level of communication with the employees, it will likewise enable all staff members to have usage of the company’s intranet and internet service provider at the same time.
Additionally, it is important that you choose your internet interconnection provider cautiously. Although your business may be looking at a excessive internet connection, your employees might actually prefer a more economical connection just like DSL or perhaps Cable. Both equally DSL and Cable present reliable www.espacodamodabr.com.br and fast connection rates of speed that would certainly not break the bank. Many small business mobile systems today also offer Voice over ip along with standard cell phone service. If the office uses either VoIP or common telephone service plan, it is very important that you pick a provider that provides these companies together, including a reasonable value.
Smaller businesses happen to be increasingly going towards cloud-voip phone service instead of traditional phone lines. It is because of a variety of factors. Impair services are highly scalable and may easily squeeze into a smaller company budget. Businesses can also realize that while traditional telephone lines can be pricey to install, impair voip telephone service can also be create and monitored by specific employees for a fraction of the expense of a traditional PBX. Also, businesses that employ cloud voice over ip phone systems are frequently able to save money on long distance charges once used in mix with other connection tools just like email and conferencing.
Upon having decided to progress your business phone over to cloud based Voice over ip systems, there are lots of things you have to consider. Depending on your employees’ locations, the sort of connection applied, and how each uses your business cellphone systems would depend on several things. For example , if your personnel are located across the world, it may be required to have worldwide calling features included in your organization phone systems. Also, should your employees use their telephones for business telephone calls overseas, you must ensure that the overseas alternative to your business are compatible with cloud-based companies. You must also keep your business telephone service provides the required encryption and authentication to produce international voice-data transfers protect.
Smaller business phone systems can be focused on satisfy specific organization requirements. Many providers give customizable software applications that can be further more modified by addition more features or by changing existing adventures to suit a particular company’s requires. In many cases, these kinds of customization features are available at no additional price to the customer.
Small businesses that are while traveling a lot can still benefit from cloud-based business telephone systems as it enables them place their hosted VoIP assistance on a dedicated network. With this functionality, employees can merely log in with their service provider’s website and make calls by anywhere they can be. These solutions allow employees to make calls from pcs that are located at any position, which removes the need to present employees with physical use of a cellular phone. The flexibility given by a cloud-based service provider allows small business owners to manage all of their employees’ phone use even though they are away from office.
Business phone systems that are organised on a dedicated internet connection are generally the best option to get companies having a large workforce. These offerings provide top-notch sound quality and allow employees place calls using headsets and accessories using their company personal computers. Cloud-based phone service companies usually give unlimited getting in touch with plans hence employees can easily talk as much as they want. Web-based office phone service providers also offer various connection tools including instant messaging, forums, and web collaboration. These types of communication tools can help boost productivity in the workplace, and it allows employees to be even more productive and creative when away from the business office.
