BlackBerry Denies Samsung Is Trying To Buy It, And Now The Stock Is Tanking Read more: http://www.businessinsider.com/blackberry-samsung-acquisition-denial-2015-1#ixzz3OrBifPHA

BlackBerry denies that Samsung is trying to buy it, following an earlier report from Reuters that said Samsung was willing to pay as much as $7.5 billion for the company.
The Reuters report sent BlackBerry shares skyrocketing almost 30% at the end of trading Wednesday.
BlackBerry shares began correcting themselves following the announcement. They were down about 15% in after-hours trading.
Here's the statement from BlackBerry:
BlackBerry Limited is aware of certain press reports published today with respect to a possible offer by Samsung to purchase BlackBerry. BlackBerry has not engaged in discussions with Samsung with respect to any possible offer to purchase BlackBerry. BlackBerry's policy is not to comment on rumors or speculation, and accordingly it does not intend to comment further.
The statement from BlackBerry leaves very little wiggle room. It sounds like the Reuters report was completely wrong.
The Reuters report said Samsung wanted to buy BlackBerry for its patent portfolio. But the price seemed suspect. BlackBerry's patents were last valued at $2 to $3 billion. The alleged $7.5 billion figure would've been quite the premium.

Facebook Unveils Facebook At Work, Lets Businesses Create Their Own Social Networks

About six months ago, we reported that Facebook was working on a new product aimed squarely at the enterprise market under the working title, “FB@Work.” Now that product is officially coming to light: today the company is launching new iOS and Android apps called “Facebook At Work,” along with a version of Facebook at Work accessible via its main website, which will let businesses create their own social networks amongst their employees that are built to look and act like Facebook itself.
(Facebook At Work is now available for download on iOS, and we’ll update with a links to the Andrid version once it’s live, though both are usable via a limited pilot to start with. Check out our follow-up story for more screenshots, details on privacy, and analysis of “How Facebook At Work Could Shrink Faceless Enterprises“)
Employers can create separate log-ins for employees to use with their Work accounts, or users can link these up with their other profiles to access everything in one place.
The product puts Facebook head-to-head with the likes of Microsoft’s Yammer, Slack, Convo, Socialcast, and a huge number of others who are trying to tackle the “enterprise social network” space. Even LinkedIn conveniently let drop last night that it too was looking atbuilding a product for coworkers to communicate and share content (but not chat, as a LinkedIn spokesperson tells me). Not all of these have been a hit: Lars Rasmussen, the engineering director at Facebook who is heading up the project, had in his past once headed up one of the failed efforts at an enterprise social network, Google Wave.
Facebook is positioning today’s debut as a bold first step. “We’re putting the app into the app stores so that we can begin testing the product,” Rasmussen said in an interview.
In fact, Facebook has already been running tests of the service with “a very small set” of external businesses around the world, Rasmussen says; this is the next step in that process. The aim initially will be companies with 100 or more employees. (In fact, the existing Facebook Groups product is already used by smaller organisations.)
Because of the early nature of the product, there are a lot of questions in the air. The company has yet to work out, for example, how it might price the app, whether it will monetise the service through ads, or how third-party apps will work. For now, Facebook Platform has been disabled on the Work product, meaning no ads or apps.
That may not always be the case (“It could be paid,” he says).
This beta state of affairs is in some ways ironic. Rasmussen says that Facebook has effectively been working on Work for the last 10 years, because it is based on what Facebook’s own employees have been using to communicate with each other, pass on news, plan meetings and share documents. That long-time use and Facebook’s familiarity to all of us are part of what makes Facebook confident that it can carve a place for itself in a market that already is very crowded.
“Facebook at Work’s strength is that we’ve spent ten years and incorporated feedback from 1 billion active users,” he says. “All of that is embedded now in the same product but adapted for different use cases.”
And it’s actually used by staff. “When Mark [Zuckerberg, the CEO] makes an announcement he just posts it on Facebook at Work,” Rasmussen says.
In fact, Facebook’s own popularity could be Facebook at Work’s biggest advantage. A lot of efforts in offices to get employees to collaborate more with each other have been stymied because employees don’t want to use the software. It’s yet another new thing to learn and doesn’t feel essential.
A lot of messaging apps (Microsoft’s Yammer being one of the notably early movers) have tried to tap into “consumerization” — or getting enterprise apps to look and feel more like consumer apps — to encourage usage. In that vein, Facebook at Work, built essentially on Facebook itself, will be arguably the closest of all to an authentic “consumer” social experience.
Here’s a run-down of some of the key points about the service, as told to me by Rasmussen:
Pricing. As noted above, no firm details on this yet but consider that most of the other apps offer tiers of pricing. By making this free, Facebook could potentially drive a lot more users to its wider network.
The fact that Rasmussen would not rule out advertising as an option down the road to me suggests that Facebook could consider tiers of its own where some businesses may pay for the product and have it ad-free, while others might take it free and get ads. Again, most enterprise apps are based on a paid model so it’s probably more likely to remain the case here too. Plus this would give Facebook another revenue stream beyond ads and app-related payments.
How it will work. Facebook wouldn’t show me a demo ahead of the launch but this is how Rasmussen describes it: “When an employer adopts Facebook at Work, they can construct it with a set of new accounts. Users can then link their work and personal accounts together so that they are logged into both at the same time.”
This would work much like Groups and public profiles do today. On mobile, you would have two mobile apps running at the same time, he adds. “Even if the employee chooses to link there is no crossover. The content stays entirely within your personal or work Facebook.”
What’s not there/integrations. You can share documents today but for now there will be no in-app editing “currently.”
Again, that leaves this open as something that will come down the line. “The set of features are identitcal to personal Facebook, but just to get it out sooner we’ve disabled the Platform so the APIs that third parties work with are not there, but we are keen to turn it back on. Hopefully in the future other enterprise tools will integrate with Facebook at Work.”
Backstory on development. Back in June I’d deduced that Facebook at Work was connected with Rasmussen’s work in London, but what I found out from sources after that report was that this was more than casual: this was his baby.
Rasmussen is not shy to bring this up himself (which I have to admit is refreshing to hear, because people do like to posture a lot in tech, don’t they).
“I can say that the challenges of making work more efficient is something that has been on my mind for a long time, and I come to it with a lot of passion and the knowledge of a failure of doing this at a different company,” he says, referring of course to Google Wave.
“I thought that maybe Facebook’s experience was what was needed. When I worked on search here it was always at the back of my mind, so later I picked back up on that idea, joined in on the conversation.”
The caveat to all this, however, is one that Facebook will have to continue to grapple with, all the more so as it continues to grow.
Canvassing opinion on a Facebook at Work product, I heard not only once people shy away from the idea, concerned with the thought of Facebook “owning” your data and the potential lack of confidentiality resulting from it.
That can be frustrating when related to pictures of you too drunk when you were in college, or frankly scary looking when you were in high school, but potentially very costly and illegal if proprietary work information is involved.

How to Use LED Grow Lights

How to Use LED Grow Lights

LED grow lights, or Light-Emitting Diode lamps, are an increasingly popular choice for indoor plant growing principally because they can deliver more intense light output with less energy and heat production, and they have a much longer useful life than that of high pressure sodium, fluorescent, high-intensity discharge or incandescent lamps. Most grow lamps are used commercially and industrially, but some residential use occurs. LEDs are made in several colors to mimic the ranges of natural sunlight that drive maximum photosynthesis and plant performance. LED grow lights are also popular because they can be used in standard bulb fittings and do not require special ballasts or non-standard electrical fixtures. LEDs come in 2-watt to 15-watt equivalents and in a range of sizes and colors.


nstructions
1
Determine the optimal lighting requirements for your particular plant or plants to thrive if they were living outdoors. Figure out the intensity of light and for how many hours a day it is needed. Often this information is on the plant tag or little plastic pick stuck in the soil of your plant. Online garden resources can help you make the determination if your plant is unmarked. This is what you need to mimic indoors with LEDs. If your plants grow outdoors in shade they need less light indoors. If they are vegetables and grow in full sun for 14 hours per day outdoors then that is the bar you must meet in order for the plant to thrive indoors.

2
Provide a mix of red spectrum and blue spectrum LEDs. Plant photosynthesis is most responsive to these two spectrums. According to research conducted by NASA, mixing at least 80 percent red LEDs and roughly 20 percent blue LEDs is a successful ratio for growing plants indoors. You can easily switch out a few of the blue LEDs for white without harming the plant growth. This will allow you to see what's happening with your plants much more readily because white LEDs have a spectrum of green, yellow and orange, which is more easily visible to the human eye.



Adjust your LEDs to hang above your plant tops by anywhere from 5 inches to 20 inches, according to the plant's size and light intensity requirements. Your goal is to have the plant greens showered in light to their edges but not have the light spill or be wasted on surrounding areas where there are no plants. Height adjustment of lighting helps achieve this economy as plants grow, changing in both shape and size.

4
Determine if your plants require light and dark periods. If so, connect your LED lights to a timer to regulate their on and off cycles to save you time, worry and labor. If your plants prefer long daylight periods and short night periods, program the automatic timer for that length of light cycle.

How Much Energy Do Christmas Lights Use?

How Much Energy Do Christmas Lights Use?

If you plan to use a lot of Christmas lights but do not want an unwanted "gift" when you open your electric bill in the New Year, you might want to buy Christmas lights that do not use too much energy.

Other People Are Reading


LED Lights
Using LED (Light Emitting Diode) lights can save you big bucks. According to the Long Island Power Authority, using a string of 600 LED lights for a month will cost a fraction of what it will cost to run "traditional" Christmas lights. A study by the Neighborhood Network says they use only .04 watts per light.

Mini-Lights
These are the smaller bulbs that are popular. The Neighborhood Network says "traditional" mini-light bulbs use about .34 watts per bulb.



C-7
These bulbs are 1 inch long that some say are shaped like a strawberry. According to the Neighborhood Network, each C-7 bulb uses more than 100 times the energy of an LED.

C-9 Bulbs
C-9 bulbs look like the C-7s but are bigger and use twice the energy.

Benefits
LED bulbs save money on your electric bill and also help the environment. The Long Island Power Authority says LED lights do not have a filament, so they do not get hot. LIPA also says LED lights can last 50,000 to 100,000 hours. That compares with the lifespan of a conventional bulb of around 1,500 hours.

how to Test a High Power Diode

How to Test a High Power Diode

Defective high power diodes are a common problem with microwave ovens. These diodes play a critical role by changing the high voltage alternating current (AC) supplied by the high voltage secondary winding of the power transformer into high voltage direct current (DC) that is needed by the magnetron tube that produces the electromagnetic energy that cooks your food. High power diodes subjected to thermal and electrical break down can cause your oven to fail to cook food although it appears to be working

A defective high power diode is found using a digital multimeter (DMM) or an analog volt-ohm-millimeter (VOM). A more accurate test can be made with a simple homemade test jig that allows you to measure the actual barrier voltage drop.

Instructions
Build the Test Jig
1
Plug in the soldering iron and allow to heat up. Once hot, clean the tip by rubbing it on the wet soldering sponge.

2
"Tin" the clean soldering iron tip by applying a coating of Rosin core solder. A properly tinned soldering tip will appear a bright silvery color and is essential for making proper solder connections.



Strip ? inch of insulation from the ends of the two lengths of hook-up wire.

4
"Tin" the bare copper ends of the hook-up wire with the Rosin core solder by applying the tip of the soldering iron to the underside of the wire and the solder to the top. The heat will draw the molten solder completely around the wire and between the strands.

5
Solder one of the lengths of hook-up wire to each battery connector lead. There will be no tension on these leads so you can simply lay the ends side by side and solder together. Wrap the soldered splices with electrical tape.

6
Solder one lead of the resistor to an alligator clip and the other lead to one of the leads coming from the battery connector. Wrap that soldered splice with tape.

Testing a High Power Diode
7
Identify the cathode and anode leads on the power diode. The cathode, or negative (-) lead, is usually identified by a solid line on the rectifier's body. The anode, the positive (+) lead, is identified by a solid arrowhead pointing against the cathode line.

8
Attach the alligator clips to the diode leads, the negative battery lead to the cathode and the positive battery lead to the diode's anode lead.

9
Snap the battery connector on the battery.

10
Set the DMM for the DC Volts range and attach the positive probe to the diode's anode and the negative probe to the diode's cathode and note the voltage reading. A reading of 12 volts indicates an open diode and you need to replace it. A reading approximately 0.3 to 0.7 volts indicates a good power diode. Most silicon power diodes have a barrier voltage drop of approximately 0.5 volts.

How do I Make a LED Flash Light for a Dashboard?

How do I Make a LED Flash Light for a Dashboard?

A flashlight on the dashboard of your car can be a convenient addition that helps prevent those frustrating moments when things seem to disappear beneath a seat or you need enough light to read a map. The 12-volt power supply used by the car's cigarette lighter is a handy power source for a low-current LED flashlight that you can make yourself. Keep it in the car for the next time you need a little bit of light.

Instructions
1
Separate the lid from the 35-mm film canister. Poke four pairs of holes in the lid using the pushpin. Each pair of holes should be spaced 1/4" apart to accommodate the two legs of an LED light. Push one white LED into each pair of holes, arranging them so that the long leg of each LED is next to the short leg of the LED next to it.

2
Connect the LEDs in series by twisting the pairs of adjacent legs together. You should have one short leg and one long leg left unconnected.



3.Poke two holes in the bottom of the 35-mm film canister with the pushpin. Untwist three inches of the copper wire and then thread the two red and black wires through the holes.

4
Twist the red wire around the long leg of the LED array and the black wire around the short leg of the LED array. Use small pieces of electrical tape to insulate the connections, and then place the lid of the 35mm canister back on to secure all the flashlight components.

5
Separate an inch of wire on the free end of the copper twisted pair wire. Match the colors to the wires of the 12-volt car adapter plug and connect them, black to black and red to red. Plug the adapter in to make sure the LED flashlight lights up. If it doesn't, try reversing the order of the wires, so that red connects to black and vice versa.

6
Tear the hook and loop tape apart, and remove the non-stick cover from the sticky back of the loop side before pressing it firmly against the location on the dashboard where you want the flashlight to rest. Remove the non-stick cover from the sticky back of the hook side of the tape and wrap it around the 35imm film canister. When the flashlight is not in use, you can keep it secured to the dashboard with the hook and loop strips.
