CA Governor Signs Self-Driving Cars Bill

September 27, 2012 by Richard Vincenti Jr Leave a Comment

California Gov. Jerry Brown recently signed a Self-Driving car bill at Google’s headquarters. The bill is designed to help lay out safety guidelines for self-driving cars.Robot Driving Car

Google co-founder Sergey Brin talked about how autonomous cars will make our roads much safer and will allow others who would not normally be able to drive, to have a personal, safe, and reliable mode of transportation.

It all sounds like science fiction but autonomous cars already exist and the technology is getting better. We already have cars that park themselves, so why not keep going and take the technology further?  My current question is, would you ride in a car that you’re not controlling? I don’t know exactly how I feel about this but if it had been through extensive testing and had a override switch, then I guess I’m game. A few questions come to mind when I think about self-driving cars. I would imagine that if you take human error out of the equation you can increase travel speeds. Why not have speed limits of around 200mph?

Being able to have cars navigate themselves though dense fog,heavy rain or even driving at night would be a huge benefit for anyone. Perhaps we can wipe drunk driving out of the picture for good as your car can take you home safe and sound.

My major concern here with anything that becomes computerized and automatic is can it be hacked? Actually, we should be asking how will it be hacked because this technology will be vulnerable just like anything else we create and something like this could be dangerous in the wrong hands. There would have to be some digital connection to your drivers license that identifies a driver or passenger, kind of like in the movie The Fith Element, and there would have to be some way to detect whether or not drivers are using a “modded” vehicle that may allow them to exceed regulated speeds or drive irradically.

Another major concern of note here is liability. These self-driving cars will inevitability mess up at one point and damage other cars, property or people, and who will be responsible? How do you determine who was at fault? Computer “A” hit Computer “B”? Send the bill to the auto manufacturer? These are all questions we will have to answer when we move into a world with self-driving cars.

The bottom line seems to be that the potential safety advantages of having a self-driving car are what will push this technology forward. With law enforcement cracking down on texting and making phone calls while driving, this seems like an obvious direction to head. We really have nowhere to go but up here, traveling by car is a dangerous task. Perhaps we will be looking back many years from now and talking about  how crazy it was that people used to drive themselves around and how inefficient and scary that must have been.

Guide To Understanding The Technology of OLED and LED LCD

September 26, 2012 by Richard Vincenti Jr 1 Comment

Many of us hear the terms LED LCD and OLED and assume that they are pretty much the same thing, and some people might not even know the difference between LCD T.V’s and LED LCD T.V’s. One reason for all of this confusion is the way that manufacturers market their products and how they refer to the new “technology”  that they put into their devices.LED Abstract Image

A liquid crystal display (LCD) does not emit light itself, it requires some type of back light in order to see whatever is on the screen.  LCD screens basically control light, sometimes they let it through and sometimes they don’t, this is what produces the image we see. Using voltage and transparent conductors, each pixel can be controlled precisely.

When LCD screens first came on to the market they were primarily backlit by CCFL or Cold Cathode Fluorescent Lamps. These CCFL lamps are usually positioned at the edges of the LCD screen and then a light diffuser is used to spread the light across the entire screen. This method of backlighting works really well but dose not produce a very good black. The reason this method doesn’t produce a good black color is because the CCFL lamps remain at full intensity even when displaying the darker part of images, which results in a glowing effect on the screen. Often we hear commercials for T.V’s mention that they have blacker blacks, they are referring to the contrast ratio which is directly related to how backlighting is managed.

More recently, manufacturers have been using small LED lights to illuminate the LCD screen. The LED’s can be placed at the edges of the screen and the light they produce can be diffused just like the CCFL back lighting method. LED lighting uses much less electricity and are much smaller than CCFL’s, which mean you can have a thinner, lighter, and more energy efficient display panel.

In order to achieve a better contrast ratio manufacturers began to dim the backlighting when darker images appear on the screen but this method only helps when the majority of the screen is dark, which is rare in most cases and means that the contrast ratio is basically the same for the majority of what your watching since the display almost never dims. So, how can we get a better contrast ratio for every image that appears on the screen?  This is where WLED comes into play. WLED uses an entire array of LED lights that span the entire area of the LCD display. WLED allows for dimming in very specific locations of the screen which results in a very good contrast ratio. Another variation of WLED backlighting involves using RGB LED lighting instead of pure white LED’s. RGB LED  backlight screens produce superior color compared to an all white WLED display and also have a solid contrast ratio.

So now that we have a basic understanding how how LCD screens are illuminated we can start to look at why OLED is actually quite different.

Organic Light Emitting Diode or OLED technology, as the name suggests,  is an LED that uses organic compounds that emit light when electrical current is applied to them. As we mentioned before LED LCD T.V’s use and LCD screen that is backlight by LED lighting, with OLED displays, the OLED itself is the display, which means there is no need for a backlight. Since OLED displays lack a backlight they offer extremely dark blacks and very vivid and precise colors. OLED’s are basically flat in comparison to traditional LED’s which resemble little bulbs. With OLED’s being so small, manufactureres are able to make extremely thin and even flexible displays.  OLED is relatively new and still has a lot of issues including saturation problems. OLED is also quite expensive at this time due to a difficult manufacturing process.

So where does Apple’s Retina display fit in? Well Apple does utilize LED backlight LCD screens that are similar to other displays, except Apple has squeezed in more pixels which creates a higher pixel density, so high that Apple claims the human eye can not see pixelation from a normal viewing distance.

So next time you head out to buy a new display, you can walk into the store with confidence now that you have a better understanding of  how todays display technologies work.

Ready or Not Windows 8 is On it’s Way

September 25, 2012 by Richard Vincenti Jr Leave a Comment

Well, it’s been really fun talking about how different Windows 8 is and how crazy it all seems but we are slowly approaching the release date for the new OS and some feel it just isn’t ready.

product_win8-startscreen_Web

I would argue that any OS is never really ready when it first releases. There are so many things that will likely only be discovered when the masses begin to upgrade  and tear apart the shiny new OS. This process of fix-on-the-fly  is nothing new for Microsoft and I’m sure we won’t be happy with the new OS until the first service pack releases or maybe even the second for that matter.

What is truly important here is that Windows users really try to look at Windows 8 as something entirely new and try not to compare it to Windows 7. The world is changing and Microsoft is adapting with it, and this is a great thing. Many of us hate change and for this reason alone we tend to look at Windows 8 and feel like we will never upgrade. However, as we march forward and watch Microsoft make one of the biggest changes to it’s operating system since the ‘Start’ button, I wonder what I plan to do personally.

product_win8-keyboard_Web

Do I jump in? Do I wait a few months ? What computers do I upgrade first and do I upgrade all of them or just one? These are the questions that I’m trying to answer, even as I write this I’m trying to figure out what I will do.I have been experimenting with the developer preview and the release preview and I still feel very uncomfortable using Windows 8 with a mouse and keyboard. I don’t know why I can’t seem to shake this feeling. This OS is designed to work with touch and it feels like the laptop and desktop experience is an afterthought.

I’m pretty patient when it comes to OS software, I have tried just about every semi-popular OS out there from obscure linux based OS’s to OSX and back to mobile OS’s. Generally I give an operating system a fair shake up until it’s first major patch. Once we reach the first major patch, if I still feel it’s not working for me, I will usually move on to something else.

When we look at Windows 8 we can’t forget that it’s not just about how we feel about the new OS, it’s also about the faith that hardware manufactures put into the new OS. After all, the hardware is useless with out a good operating system to make it work. Let’s not forget that Microsoft is also going to be releasing it’s own tablet with Windows 8 on it, which will have Microsoft competing directly with those same hardware manufactures that Microsoft want’s Windows 8 to run on.

What about developers? what will they do with existing titles? How will they fit-in with the new OS? Is this change something that developers want to engage in? Some developers feel threatened by Windows 8 and feel that they will be forced to operate within a “box”.  Take the keyboard and mouse out of the equation and now you either are forced to work with touch or an Xbox controller.  Something doesn’t feel right here and I can quickly begin to understand why.

Now, take all of this crazy change and bundle it up in a nice, shiny, new Microsoft store that you build right across the street from the Apple store and you’ve got a front row seat to historic change in the world of technology.

To sum things up, I say if you support Microsoft then use Windows 8 and provide all the feedback you can to help Microsoft build the software you want to use. This is the only way they can get a real feel for what consumers want and need from their software. In the meantime I remain optimistic about Windows 8 and hope to see it succeed.

Myspace Ready for Round Two

September 24, 2012 by Richard Vincenti Jr Leave a Comment

Remember back in the day when a little site named Myspace dominated social networking? Well, we all know the story all to well of how Myspace began to loose popularity while Facebook went through the roof but now it looks like Myspace might be ready for a comeback.

The old social network was innovative but quickly began to feel very sloppy and some Myspace pages were so bogged down with content that it took forever to load a page. Now, it seems that is all in the past as Myspace has a brand new look and I must say, are you ready for it? It looks really good. The interface looks really smooth and it looks like it will fit in perfectly with Windows 8 or any other touch based OS.

Facebook brought with it a very clean feel and I still like the way it looks even now but sometimes, if it can be done well, a media rich page that showcases you and what your all about can be really nice. When it comes to social networking these days, things seem kind of bland but Myspace’s new look feels different, in a good way. I hope this works as well as it looks and maybe we can see things start to shift again. I guess we will have to wait and see.

There is a new video that shows off the new site and all of its features and eye candy. You can check it out here.

You can also head to the new myspace website directly and see for yourself.
