What Is SPDY Protocol In Google Chrome?

Have you ever heard about SPDY protocol before? In case you don’t know, it’s a networking protocol, which was developed by Google to transport contents of websites. This protocol is helping to reduce page load and improve the web security in Google Chrome.

Through the compression, the SPDY protocol will help us to lessen the size of web pages to load faster, as well as improve the security of it, especially in e-commerce stores.

At the earlier of 2015, Google announced they would not support SPDY protocol anymore in Google Chrome. The reason is that the HTTP/2 standard is better, faster and more secure than the SPDY protocol. That’s also the reason why Google want to withdraw and replace it with HTTP/2 protocol.

According to Google and Mozilla, Google has removed SPDY support in the Chrome version 51. Mozilla also removed this protocol in the Firefox version 50. The only disadvantage of the SPDY protocol is that sometimes, it causes a few annoying errors, such as Err_SPDY_Protocol_Error error. It’s one of the several annoying errors in Google Chrome that is related to the SPDY protocol.

We wouldn’t deny that this protocol from Google was helping us to speed up website load times for a while before the HTTP/2 standard release. However, with the disadvantage of it, most of the internet browsers, including Google Chrome, Mozilla Firefox, Microsoft Edge or Opera are abandoned it already. Instead, they moved to use HTTP/2 as the replacement solution, which is faster and of course, more secure than the SPDY protocol.

For further information regarding the SPDY protocol, such as the goals, history, versions, and which programs support it, visit the Wikipedia.org’s web page here to read it.

Actually, most of the browsers don’t abandon the SPDY protocol yet. They are just upgraded to the new version. The current version of SPDY is 4.0 alpha3. It is more closely aligned with HTTP/2 standard and has a new stream flow control with the HTTP/2 draft.

In order to learn more about SPDY, its features and how does it actually work, read this article. You can also find the SPDY frequently asked questions there, with answers.

Why Linux On The Desktop Is Toast?

Linux succeeding as a desktop operating system as been discussed forever. I’m a Linux software developer by trade, use Linux as my desktop at work and home, but I see the future for it on the desktop to be quite bleak. I discuss the major reasons why below.

Before we discuss this issue, we need to determine what a Linux desktop operating system is. Linux distributions such as Redhat, Suse, and Ubuntu are clearly Linux desktop OSes. However, what about Chrome OS? Google’s upcoming operating system utilizes the Linux kernel, however it has a much different user interface than the typical Gnome or KDE environment that comes with most Linux distributions. Although it is not out yet, it also appears that they will not be offering common Linux utilities such as Gimp and OpenOffice, favoring their own web based applications instead.

For the purposes of this discussion, I am doing to define a Linux desktop OS as an operating system that meet two criteria. One, changes and modifications to the components, both user space and kernel space, are actively shared amongst all the Linux desktop distributions. Two, it is actively advertised and described as Linux. In my opinion, a “Linux desktop” refers to a common set of open source components and the philosophy of open source sharing, and thus is advertised that way. While Chrome OS utilizes the Linux kernel and open-source, and contributes back, my feeling is that Google is doing their own thing. They are intending to make Chrome OS its own identity, that isn’t identifiable with other Linux distributions. For that reason, I’m not going to consider Chrome OS as a Linux desktop operating system. Another way to think about it, how many times have you heard Android referred to as a “Linux OS”? Or how many times have you heard that Apple products run a “Mach kernel OS”?

I will ignore the question of what market share Linux must obtain to call it a success on the desktop, since opinions will vary greatly. At the minimum, all Linux advocates would agree more market share is required for it to be a success.

Linux Can No Longer Compete on Price

At the time of this writing, the cheapest Windows netbook that Dell sells is $300. Dell’s equivalent Linux Ubuntu netbook is listed at $300 dollars. The cheapest desktop offered by both Dell and HP is $300 dollars. For desktops, I have yet to find an online retailer with a comparable Linux desktop for atleast the same price. While this data is limited, I hope these numbers illustrate a simple point. The advantage that Linux once had on price has evaporated. This has happened for a variety of reasons, including more competitive pricing, but one of the major advantages Linux had is now gone.

I recall an article I once read on disruptive technologies. In it, Henry Blodget states, “Disruptive technologies take advantage of a new manufacturing/business process or technology to provide a cheaper, more convenient, simpler solution that meets the needs of the low end of the market. Low-end users don’t need all the features in the Incumbent’s product, so they rapidly adopt the simpler solution.”

Linux on the desktop was expected to be this disruptive technology. The old saying was, “If a grandma needs a computer just to check e-mail from her grandkids, there’s no reason for her to pay more money for a PC.” Well, grandma no longer needs to pay more money, so why would a person unfamiliar with Linux now buy it? Grandma has no incentive to switch.

Granted, when you add other applications such as MS Office, a PC will be more expensive. At the time of this writing, a home version of MS Office is listed for $150 dollars, and can be found for $100 on Amazon. It’s a far cry from the $300-$400 dollars it once cost. The key point is the price gap is significantly shrunk.

Linux Must Compete On Features

The flip side of the previous point is that Linux must now compete on features and functionality to succeed, price is a much smaller competitive advantage for Linux. Microsoft and Apple are aggressively developing better experiences on their operating systems and making better applications that run on it. It does not appear Linux has the resources to compete. Google, perhaps Linux’s biggest supporter from a huge tech company, is the one company that could perhaps push that forward. However, as I mentioned earlier, it appears Google has limited interest in supporting a user interface or Linux applications outside of their cloud.

There are Too Many Linux Distributions

While open source is one of Linux’s greatest attributes, it’s also one of it’s greatest flaws. With so many different distributions of Linux, it ultimately makes it more difficult and costly for software developers to develop software for all flavors of Linux. In addition, individual customers may modifying their Linux distributions for their own internal needs, which simply leads to more portability problems.

This may be the smallest issue of all the ones I’ve mentioned in this list. If one of the distributions can become the clear winner over the other on Linux desktops, this problem could dissipate.

Third Party Applications

Ultimately, for the Linux desktop to succeed, major third party applications must be ported over to it. Classically, people discuss video games as the major limiting “killer app” that must exist on Linux. However, other major software from Adobe and Oracle must also be ported. This single handedly will prevent many customers from switching to Linux. There are multiple issues why this exists, such as the fragmentation problem discussed above. However, I believe the issue at its core is just a chicken and the egg problem. Developers will be unwilling to port to Linux as long as it has such a small market share. However, in order to get people to switch to Linux, more developers need to support Linux.

OS Consolidation

The question is, how many desktop operating systems can the market have? Historically, the answer is not a lot. The need for interoperation of systems will ultimately limit the number of operating systems that can exist. Software developers want to have their software work for as many people as they can, while consumers want familiarity. With Google entering the desktop OS war, I am reluctant to believe that Redhat, Suse, or Ubuntu are going to be able to make inroads in an even tougher environment. I doubt they will become the next BeOS or OS/2, but Google’s entry into the market won’t help.

Summary

This article does not make the point that Linux is dead on the desktop forever. It’s only for the relatively foreseeable future. However, the above points illustrate that Linux has a lot to overcome to become a success, and nothing over the past few years has made it easier or cheaper to accomplish.

Should You Buy A Laptop Or A Desktop Computer?

If you are shopping for a new computer, then you have to consider many things when deciding between a laptop or a desktop. Where will you be using your computer? Will it be at home or in your office? Offices tend to prefer desktop computers because they do not want the computers to be moved in the first place. You will also need to know what your budget is before you can decide to buy a laptop or a desktop. There is usually a big price difference between laptop and desktop computers.

As you are looking around for a computer, you want to know some of the main differences between laptops and desktops. The purpose of this article is to highlight the main differences between laptops and desktops. The rest of this article will cover those differences so you are prepared with the knowledge you need when making your decision.

– Desktop computers typically cost much less money than laptop computers. Laptops tend to cost more money than desktops because they are so compact and portable. What you are really paying for here is the convenience. For close to half the price of a laptop, you could get a comparable desktop. If you’re on a tight budget, this will probably be an important factor for you.

– Laptops can be much more difficult to repair and upgrade. Desktop computers, for the most part, are “plug and play.” You just open the desktop up, pop out what isn’t working, and replace it with a new part. I’ve done a lot of upgrades and replacements on my desktop; it’s always very easy. With laptops it’s not always this easy. Many laptops need to be serviced by a professional for repairs and upgrades.

– Desktop computers are far less likely to be stolen, simply due to the fact that they are harder move. Laptops are designed to be light weight and portable, which makes them super easy to steal. In other words, I’m not worried about anyone running off with my huge DELL that I don’t even want to move. This may sound kind of silly and obvious, but it is a very real point to be made. A lot of college kids have their laptops stolen right on campus by someone who just runs by and grabs it.

– Desktop computers have better ventilation, so they are less likely to overheat.

If you need your computer for travel, then obviously a laptop is the way to go. Other than that, though, there are really no benefits to having a laptop over a desktop computer. If anything, it’s other way around. Laptops are small, convenient, and can be taken anywhere… and that’s what you’re paying for when you get one. As far as specs, performance, and maintenance, desktops always give you more for your buck.

Is A Laptop Computer Better Than A Desktop?

Every time I get to the point where I need a new computer, or even think about buying one I always come to this one major fork in the road. Should I buy a desktop computer or a laptop computer? For many people it may not seem like a very big question to ask but for someone with the kind of lifestyle that I have it is actually quite important. For example I travel a lot, here in Panama you are only given visas for three months at a time and when your time is up you must leave the country for a minimum of two days before returning to Panama. That means that if I own a desktop computer which I use every day, I must leave it behind for the amount of time that I am traveling.

So when it comes to travel a laptop of course is much more convenient to have. However I have found that desktop computers are generally more stable machines; and for a gamer like myself they also tend to run games much better. However as I mentioned you can’t just haul them across the border whenever you like. Laptops are also very nice for a writer like myself. It allows you to write anywhere you go, and it allows you to get away from the desk and go outside and write. Staring at a computer screen all day every day in the same room can be rather stifling. So to have a laptop to take outside and write out a few articles in the fresh air is great.

Now what is definitely something very important to mention about desktops, which puts them on top for many people is upgrading. A laptop computer is more complex and difficult to build than a desktop. It is also much harder to upgrade a laptop computer than it is a desktop. Now this is probably more relevant to gamers who know how quickly technology changes. You can buy the best computer on the market and within a month there will be a better one out there and new games that the computer you have can’t even handle. Basically it is just nice to know that even though your computer will be out of date soon that you can buy new parts and have a whole new computer for a much lesser price.

Which brings us to the final point. The price of laptop computers are much higher than that of desktops. This of course being a major factor for many people. You can buy a very nice desktop computer for less than a thousand dollars. A laptop computer of the same caliber however will often times be at least a couple hundred dollars more. I recently went computer shopping and often found laptops that easily cost $500 more than a desktop and were still not as fast and with less hard drive space.

So when it comes to my opinion, I think that a potential buyer should generally stick with a desktop. Unless of course they travel often in which case a laptop is necessary. Everyone has their own opinion on this matter. Some may defend their laptops with passion and others their desktops. To finish I will say that if one has the finances and and the need, they can just buy both and have the best of the two worlds! To those of us who don’t have those kinds of finances, choose wisely. Look at your lifestyle and see what would be the best for you. Then go and purchase the perfect computer for you and enjoy it!

Tablets Vs Desktops and the Evolution of Internet Content

Content Creation and Consumption is Changing the Form and Face of Computing
During his recent keynote address, Steve Jobs declared that the tablet form factor is the future and that the desktop PC era is coming to an end.

While my personal computer inventory and my computing habits might point to a future without desktops, the reality is that the desktop computer will be around for a while. At the same time, while personal computing devices are evolving into tablets, desktop computers must evolve in order to stay relevant.

Tablets and the Future – How Computing is Changing

Computing is changing: technology and devices are simply adapting to accommodate the new paradigms of how people access information. During the early days of the Internet, most people online fancied themselves website designers. It seemed that everyone had a website, and the Internet was clogged with amateur website hosting services like Geocities and Angelfire. As the Internet matured, we became content producers that used our computers to document our lives through blogs and video-blogs. Everyone was producing web content, and most of us needed desktops or at least a competent laptop to accomplish this. Now, things have changed.

For the most part, we have shifted from being producers of content to consumers of content, and the limited web content we do create is all created in bite-sized chunks. When it comes to 420 characters on a Facebook status update or 140 words in a tweet, a desktop computer is simply overkill. We use our smartphones, many of which like my Motorola Atrix are far more powerful than my desktop was 12 years ago, to update our status or send a message to a friend. We snack on information through Wikis and snapshots rather than gorge on information in libraries. The tablet form factor was the natural evolution of a computing device for this content snacking.

Back when the world was obsessed with updating the animated background on a Geocities page, we still received most of our information and entertainment on television or in print. Now we get our information and entertainment from Hulu.com, Netflix.com, CNN.com or other news websites. Even magazines, newspapers, and books are delivered electronically. Tablets are the best device imaginable for content consuming and information snacking. We want information on the run, and even a laptop is too cumbersome and clunky. I can’t imagine carrying around the dozen magazines and a few books that I hop between on my Nook Color.

Tablets and The Future – Where Does Content Come From?

Someone still has to create all of the content. Granted, Youtube videos and Facebook status updates are created on Smartphones and Tablets, but someone is sitting down at a desktop and creating the electronic version of Men’s Health and Maxim that I read on my Nook Color, and you can bet your iPad 2 that a desktop was used to do the design layout of the print version that the electronic version was based on. The production, layout, and programming for the entire web is done on either a laptop or a desktop. Even I am writing this article on my iMac. I can’t imagine trying to hack this together on my Motorola Atrix or an Apple iPad. Desktops have a purpose, even in our consumption model. That purpose is at the top of the content consumption food chain.

I think of desktops and full-sized laptops as the earth moving machines, dump trucks, and work machines that are necessary to create the roads and infrastructure that makes everyday life possible. Tablets, smartphones, and ultra-mobile netbooks are the convertibles, hybrid vehicles and motorcycles that we all long to drive. The roadside is fun to watch from a convertible, but if it wasn’t for a a cement mixer, there would be no road to zoom along.

Tablet Computers and the Future – What’s Next?

I don’t know if tablet form factor computers and smart phones will ever be able to replace a powerful and scalable desktop when it comes to our current paradigm of programming and content creation. The future depends on what kind of content consumers we become. If content is driven by cloud computing and storage and real-time augmented reality applications, then a tablet, Nintendo 3DS, or a smartphone is all that we might need. Once content can create itself, or code can be compiled in real-time by powerful and adaptable computing devices, we will only need consumption devices.

It isn’t fair to say that the PC era is over; it is fair to say that the traditional methods of content creation have ended. As more content is delivered electronically, and the messages and content continues to become bite-sized, tablets are becoming more useful and relevant.

How To Use Real Desktop Program?

In this tutorial I will show you how to use Real Desktop and tell you what it is. First, I will start off by explaining what Real Desktop is. If you already have the Real Desktop installed, skip down to the next part to learn how to use it.

What is Real Desktop?

Real Desktop is a program that you can install on your computer and it gives your desktop a life like desktop. The new desktop is at an angle. At the top you will see a glass sitting there. You can twist and turn the icons. If you are tired of looking at your same desktop, try using the Real Desktop. Please see the image that I have provided to get a visual of the desktop. I captured my screen and shrunk it down. That’s why it looks so small.

How do you use Real Desktop?

To start using your Real Desktop program, go to your start menu and open your program. It will automatically start running. You can move your icons around your desktop by dragging them with your mouse. You can turn your icons by grabbing the corner of your icon and turning it. You will notice that your cursor turns into a half circle when you place it on the corner of your icon. When it turns into that, you can turn your icon.

Next, you can change your settings for the desktop. If you are using the Demo version there isn’t much that you can change. If you are using the full version, you have many options for changing your desktop. I am using the demo version but I can see the different settings that are available. I can’t apply them though.

To open your settings window left click on the silver R in your taskbar. When the menu pops up, click Settings. That will open your settings window. In this window you will see many different options. You will see the different tabs at the top of the window. Click on a tab to view the different settings. You can change the background, the icons, the color schemes, and more. You can also choose to allow Real Desktop to start up when windows starts.

If you are using a demo version and would like to purchase the full version, left click on the silver R in your taskbar and click Buy Now. That will take you to their website and there you can purchase the full version. The full version is $29.95. When you visit their site, you will notice that it is not in English. Simply click the English link at the very top of the site and it will convert everything to English.

Desktop vs. Laptop: Which is Better?

I own both a laptop and a desktop computer, so I think I can provide an equal arguement for both subjects.

I’ve owned the desktop far longer than the laptop, but I’ve managed to note many pros and cons for both. Here they are.

Desktop

Don’t get me wrong, desktops are a very good choice if you want to buy a computer, but consider this before you fork over you’re money. They are more expandable than laptops, but they have a rather large footprint by comparison. You might have to buy two whole new pieces of furniture to acomidate thier size.

A desk and a chair(more money). Eventhough they are bigger, this makes them a lot easier to take apart and fix or upgrade. But bigger often means louder. Most desktops have a large and rather loud cooling fan. The size also means more clutter in the form of dust, wires, and sometimes, even bugs.

A desktop means a tower(the computer itself), and the screen being powered by two seperate plugs(more energy use). An upside to the size is the fact that desktops usually have more ports(USB, Firewire, etc.).

And worst of all, if you don’t have some sort alternate powersource in the case of a power outage, anything you would have been doing at the time would be rudely interupted. You would’nt have a chance to save you’re work and it would be lost.

Laptop

As my personal choice, I think laptops are the way to go. Most people think laptops are more expensive, believe me, thier not. My sister’s desktop cost in upwards of a thousand dollars, and it’s a nice computer. However my laptop only ran me about six hundred, and spec wise, is better in every way. It has a better graphics card, a bigger harddrive(by almost 60 gigs), and a better processor(hers being a celeron D, and mine being a AMD 64 Athlon X2 duel core).

Laptops are obviously more portable. On a downside, laptops are a lot harder to service and usually have to be fixed by a professional costing you more money. They are not as loud as desktops, but tend to overheat far more frquently mostly due to someone puting them on a blanket or a carpet, blocking the air vents. But as long as you don’t do any of that stuff, laptops are pretty safe.

When it all comes down to it, just take a look at the specs and decide to get a desktop or a laptop.

I’ve briefly outlined the pros and cons of both. Use them to make you’re decision.

Desktop Pros

  • Expandability
  • Easier to physicly repair
  • More customizable(physiacly)
  • Often safer overheating wise
  • Often more connections(USB, Firewre, etc.)

Desktop Cons

  • Bigger/Takes up more space
  • Often louder
  • Unportability
  • A lot of wires/Clutter/Dust trap
  • Power outage = computer shutdown

Laptop Pros

  • Portability
  • Battery Power(power outage won’t matter for a few hours
  • Small/small footprint
  • Often more quiet
  • No wires(only power and peripherals if any)

Laptop Cons

  • Can be unsafe overheating wise
  • Harder to repair physicly
  • Not as much room to expand or upgrade hardware
  • Often fewer conncetions(USB, Firewire, etc.)
