Hello! 4K Ultra HD is the next generation of television. Before this, the highest resolution was 1080p. 4K Ultra HD has four times the number of pixels as Full HD (3840 x 2160 pixels). There are a few details to straighten out, but it looks like this new technology has arrived. Regular HD TV has just become old-fashioned.
4K resolution has become the common name for ultra high definition television (UHDTV), although its resolution is only 3840 x 2160 (at a 16:9, or 1.78:1 aspect ratio), which is lower than the 4K industry standard of 4096 x 2160 (at a 19:10 or 1.9:1 aspect ratio).
The screen is bigger, without the loss of resolution.
When will 4K TV hit the mainstream? The estimates are around 7 years. Yet, currently there are affordable UHDTV’s on the market.
In 2014, Netflix began streaming House of Cards, Breaking Bad and “some nature documentaries” at 4K to compatible televisions with an HEVC decoder. Most 4K televisions sold in 2013 did not natively support HEVC, with most major manufacturers announcing support in 2014. Amazon Studios began shooting their full-length original series and new pilots with 4K resolution in 2014.

When admiring fans think of the illustrious Steve Jobs, they visualize a marketing genius owning the stage. What many of us do not realize is this…Steve Jobs did play a role with the World Wide Web from the beginning.
So, if we state this correctly, the world’s first web browser was used on the NeXT Computer. This was a computer created by the company founded by Steve Jobs, after he was forced to leave Apple in 1985.
The NeXT Computer was used by Berners-Lee at CERN and became the world’s first web server. A NeXT Computer was used by Berners-Lee as the world’s first web server and also to write the first web browser, WorldWideWeb, in 1990. Has world’s oldest known WWW page been lost or found?
Tim Berners-Lee, a British computer scientist, launched the world’s first web browser on the NeXT Computer. The NeXT Computer was the basis for the Macintosh OS X and the iPhone operating system.
In March of 1989, Tim Berners-Lee offered a proposal to his boss, and the proposal was an information management system. His boss, Mike Sendall, gave the approval and the rest is history. Not long after this we have the invention of the World Wide Web (WWW). Tim Berners-Lee and Belgian computer scientist Robert Cailliau are considered the inventors of the Web.
On August 6, 1991, Berners-Lee published a short summary of the World Wide Web project on the newsgroup alt.hypertext (WorldWideWeb Summary). [Tim Berners-Lee, WorldWideWeb project, C.E.R.N., 1211 Geneva 23 Switzerland]
The first test was completed around December 20, 1990 and Berners-Lee reported about the project on the newsgroup alt.hypertext on August 7, 1991.
The first server outside Europe was installed at the Stanford Linear Accelerator Center (SLAC) in Palo Alto, California, to host the SPIRES-HEP database.
In 1989, CERN was the largest Internet node in Europe, and Berners-Lee saw an opportunity to join hypertext with the Internet [Academy of Achievement]:
“I just had to take the hypertext idea and connect it to the Transmission Control Protocol and domain name system ideas and—ta-da!—the World Wide Web… Creating the web was really an act of desperation, because the situation without it was very difficult when I was working at CERN later. Most of the technology involved in the web, like the hypertext, like the Internet, multifont text objects, had all been designed already. I just had to put them together. It was a step of generalising, going to a higher level of abstraction, thinking about all the documentation systems out there as being possibly part of a larger imaginary documentation system.”
What Is Digital Radio?
Digital radio is the transmission and reception of sound that has been processed using technology comparable to that used in compact disc (CD) players. In short, a digital radio transmitter processes sounds into patterns of numbers, or “digits”– hence the term “digital radio.” In contrast, traditional analog radios process sounds into patterns of electrical signals that resemble sound waves.
Digital radio reception is more resistant to interference and eliminates many imperfections of analog radio transmission and reception. There may be some interference to digital radio signals, however, in areas that are distant from a station’s transmitter. FM digital radio can provide clear sound comparable in quality to CDs, and AM digital radio can provide sound quality equivalent to that of standard analog FM.
Do I Need a New Radio To Receive Digital Signals?
Yes, a digital receiver is required in order to receive digital signals. However, all radios capable of tuning in to a digital signal also will be able to receive analog signals.
How Do I Find Digital Radio Stations?
In the United States, digital radio is broadcast using in-band on-channel (IBOC) technology. This enables radio stations to broadcast their regular FM or AM signal and their digital signal at the same frequency. So a station at 88.7 on the FM dial would have a digital signal at 88.7 on a digital radio.
What Is IBOC Digital Radio?
IBOC refers to the method of transmitting a digital radio broadcast signal centered on the same frequency as the AM or FM station’s present frequency. For FM stations, the transmission of the digital signal occupies the sidebands above and below the center FM frequency (e.g., 97.9 MHz). AM band transmissions also place the digital signal in sidebands above and below the existing AM carrier frequency. By this means, the AM or FM station digital signal is transmitted in addition to the existing analog signal. In both instances, the digital emissions fall within the spectral emission mask of the AM or FM channel (see 47 CFR Sections 73.44 and 73.317).
Where Can I Get a Digital Radio Receiver?
A lot of electronics retailers sell digital radio receivers, and many automakers offer digital radio receivers in their new cars and trucks (some models come with digital radio standard.)
1. Pyle P2002ABTI 2000 Watts Hybrid Receiver and Pre-Amplifier with AM-FM Tuner/iPod Docking Station and Bluetooth
2. Grace Digital Wi-Fi Music Player with 3.5-Inch Color Display (GDI-IRC6000) (Black)
3. Grace Digital GDI-IRDT200 Hi-Fi Internet Radio Tuner
4. Sangean PR-D5 AM/FM Portable Radio with Digital Tuning and RDS
5. Onkyo TX-SR333 5.1-Channel Home Theater Receiver with Bluetooth
Holmes Heater Receives High Marks For Safety
The Holmes Heater ranks high for safety, performance, and price.
I have not owned this particular space heater, but I have owned an older heater made by Holmes. It has performed flawlessly for years. I keep waiting for it to go bad, but it seems to keep going. I’ve never had any issues with this unit and I’m sold on the brand because of durability. Who wants a cold bathroom?
Based on my experience with a previous product, I would purchase a heater from this reputable company.

Ferocious Winter Storm In November Of 2014 Claims 6 Lives. New York Braces For More Snow.
I’ll admit that I’m a fan of The Old Farmer’s Almanac 2015. Armed with the rigorous method of tracking weather patterns, useful analysis can be digested and sent to the public, in order to prepare for the winter. What does the winter look like? Is it going to be like that nasty winter we endured last year? We hope not.
According to their weather blog, the editor informs us that it may be very cold, but probably not as bad as last winter. Her words: “Think of it as a refriger-nation.”
“Think Of It As A Refriger-Nation.” — The Old Farmer’s Almanac
Another well of information concurs the same predictions. “Cold Will Not Be as Harsh, Long-Lasting as Last Winter,” is the line coming from a writer at AccuWeather. The snow could cause some major problems, according to the expert analysis.
“Cold Will Not Be as Harsh, Long-Lasting as Last Winter” — AccuWeather
The massive winter storms have claimed six lives in the northern region of the United States.
6 Feet Of Snow In Buffalo
In fact, a ferocious winter storm has blanketed the state of New York, especially in the Buffalo area. One resident claimed there was an accumulation of 6 feet of snow in Buffalo, New York. Yes, you read that correctly. This is 6 feet of snow we’re talking about.
Winter Weather Arrives Early In US And Canada
Winter weather has arrived early in the US and Canada. The Arctic air has already slammed the northern regions.
The term Polar Vortex was the weather term that created a lot of buzz last year. What is the next catchphrase going to be?
Bombogenesis Is The Word
According to the NOAA Ocean Prediction Center, there were 20 unique hurricane force wind events between during January and February 2014. Fourteen storms underwent the process called bombogenesis, whereby a cyclone rapidly intensifies, dropping at least 24 millibars in pressure over 24 hours. The number and intensity of North Atlantic storms is higher than normally observed – and this feature can be seen in wind speed data from the period.
My new Roku media player arrived in the mail and I was in a state of bliss. Finally, another electronic gadget to render the man cave complete. You know the routine. Unbox. Never read instructions. High expectations. No patience. Internet TV not happening this time. Ouch. Roku remote control won’t work I guess. Now I need anger management! Somebody please help me!
No need to panic. The Roku Remote Control (with purple tag) has a secret panic button. Seriously folks. Pull the plastic cover in the back of remote, and you’ll see a little button. The Roku guys call it a ‘pairing’ button. You must ‘pair’ the remote with the Roku player that plugs into a wall outlet. Press the panic button and hold please! (Note: My other Roku player played fine right out of the box, with no need of pairing.)
But, be sure to unplug the Roku player for approximately 5 to 15 seconds and plug into wall socket. Then push the panic button and hold for 5 seconds. Here are a few items to check. Make sure the little plug inserted into the Roku player is properly secured.
***** Your Android, iPhone, iPad, iPod, etc. will effectively function as a remote control with Roku player. There’s an app for that.
If Roku Remote Isn’t Functioning
1. Point the remote directly at your Roku player.
2. Try moving closer to your player.
3. Make sure the batteries are working and inserted properly.
4. Make sure the front of player isn’t obstructed.
5. If the status light on the front of your player flashes once each time you press a remote button, the problem is not with the remote.
Take a sip of your favorite beverage. Inhale, then exhale. Repeat after me. I will not get angry. I will not run to the post office and ship this thing back immediately. I will not panic. Okay. Smooth sailing from here. Here’s the Roku Guide so you can browse the Roku channels. Enjoy.
1. Unplug Roku player from wall outlet.
2. Wait 5 to 10 seconds. Plug Roku player back into wall outlet. Roku logo will bounce on TV screen. This is normal.
3. Remove plastic cover (battery door) from back of Roku remote control. It has a latch to press.
4. Insert batteries properly. Smooth bottom, or battery negative goes against the big spring. Positive post touches a small coil.
5. Press and hold the pairing button inside the battery compartment for 3 to 5 seconds.
6. Wait about 10 seconds for remote LED to stop flashing.
7. Try Roku remote again. It should work.
9. Take family out to dinner. Go shopping afterwards.
10. Return home. Play with Roku as often as recommended.

Are you tired of paying the high cable bill? Have you had enough of the paid programming nightmare on satellite dish? You get hundreds of channels and yet nothing to watch? I feel your pain. Do you have a high speed internet connection? If the answer is yes, then you need Roku.
It is advisable to have 1.5 to 3mb of internet bandwidth to stream internet television, and the 3mb is the preferred choice. Roku offers streaming internet radio options as well. The remote control has a connection for headphones believe it or not.
I recently ordered the Roku 2 set top box and it arrived a few days ago. I am so impressed with Roku that I’m going to order more when the opportunity arises. For a spare room or bedroom, the Roku 2 is convenient. It’s a wireless device only, meaning that if you’ve got wi-fi, then you’re good to go.
Roku 3 offers an alternative ethernet cable connection, along with the standard wireless function.
The Roku 2 media player will work on the older style televisions as well as the newer flat-screens. The Roku 2 plugs into the TV set using the RCA plugs (red, white, yellow). It also has an HDMI slot.
If you want to stream online media and you have the flat-screen TV, then I would recommend the Roku 3 box for sure. But remember, Roku 3 will not work with the older televisions. It uses the HDMI cable only. All modern sets are equipped with the HDMI port.
The Roku 3 box is faster and the interface is more efficient than the previous edition. It’s better quality.
Here’s my experience with Roku 2 . I had it hooked up to my 32-inch flat-screen with the RCA cable (A/V cable) and the quality was great, even without HDTV connectivity. But I do want to receive the channels in HD quality, so I’ll have to purchase the HDMI cable. No problem.
I wanted to see what was available in the news category. I was delighted to surf on the many news channels that were available and most were free by the way. I also found some classic, old-fashioned horror movies. I watched The Last Man On Earth, starring Vincent Price. I have seen it before.
There are free and premium channels, such as Netflix and Hulu. The variety is there and no high-priced cable bill.
