A Breakdown of Houston Internet Providers

A Breakdown of Houston Internet Providers

Living in Houston, Texas affords a variety of choice in Internet service providers. Options can include wireless Internet, DSL, or cable, and can be packaged with television as well as telephone service, depending on your service provider and area. While wireless Internet choices are not limited by access, wired Internet solutions will be limited by service areas, of which there are many.

Wireless Internet does not refer to in-home WiFi, but rather the wireless networks used by cellphones. Connectivity can drop off quickly as you move outside the city in some areas, so signal strength can be an important factor in choosing a wireless Internet provider. Another consideration for wireless Internet is the amount of use it will get. If you intend to watch videos or download large files, you will quickly run out of bandwidth and the expense can quickly climb, so an unlimited wired connection is more appropriate for intensive usage. Wireless Internet is available through Clear Wireless, AT&T Wireless, and T-Mobile, and their coverage areas are complete though-out the Greater Houston area.

Wired Internet solutions are available through AT&T and Comcast. Cable and DSL differ from one another in one significant manner that is important to consider when choosing your service provider, and that difference can affect your real-world Internet speeds. Cable Internet service runs from homes in an area to a local node. The speed available at that node is subdivided among all the homes connected to it, so that during high-usage times the speed you experience may drop. DSL, on the other hand, does not use this node system and instead guarantees an agreed-upon speed. Another factor which will impact your choice of Internet service providers will be the service area in which you live. Neighborhoods and apartment complexes are served in blocks by providers, and therefore the place you choose to live will determine what service is available to you.

Cable Internet is available through Comcast’s XFINITY service, which can be packaged with cable television or purchased solely. DSL internet is available through AT&T, as well as their Houston AT&T U-verse service, which can be packaged with television and telephone service as well.

Android Web Apps Vs Native Apps

Abstraction is an important topic when studying mobile platforms. There was a time when developing for Android meant targeting smartphones. Obviously, this is still an important consideration for any app that will run on Android. However, at the same time it’s important to remember that Android now exists on a dizzying amount of devices. Android currently powers a wide range of phones, TVs, watches, and e-book readers. The idea of targeting every single one of these platforms with a single app can be daunting. This is why Android relies so heavily on abstraction.

A typical Android program is kept somewhat removed from lower level hardware calls. This improves overall stability, but also ensures that programs can run on almost anything. The same app should be able to run on a x86 based laptop and a ARM based smartphone with little to no differences. That said, Android provides multiple methods to achieve this goal. Android supports native app development with Java, and Web apps which make use of HTML5.

Native apps are the standard type of application for Android. When a person talks about Android apps, they’re usually talking about a native app. One of the biggest benefits of native apps is distribution. Native apps can be distributed through either the play store or other markets. Google has put a lot of work into integrating the play store with their builds of Android. The end result is that users tend to expect apps to be within their store. The other benefit is becoming less significant over time. Native apps are less demanding of both the processor and memory of an Android based device. Both native apps and web apps use something known as just in time compilation, or JIT. However, the JIT of a native app is far more efficient due to the nature of the language. Native apps use Java, while web apps use javascript. Javascript isn’t as strongly typed, and this means a lot more work for a JIT compiler. However, these days it’s fairly rare for a device to have much trouble with JIT compilation of Javascript.

Web apps can’t be sold in the Play store, but they do have one big advantage when it comes to distribution. Other mobile operating systems will probably be able to load them up as well. Google recently decided to fork the webkit codebase. But for the moment, HTML5 based code intended for an Android device should work on iOS. Even better, the default browser on both systems is based on the same general rendering engine. They use different methods of working with Javascript, but in general this shouldn’t be too much of an issue. Additionally, web apps can also be loaded up on desktops and laptops running a wide variety of operating systems.

If one has the resources to allow it, native development is still the best option. There’s just too much to be gained from the established methods of distribution and sale within current markets. However, if one’s resources are limited and there’s a pressing need to support other operating systems than web apps are the way to go. They’re still the best way to write once and run anywhere.

Nanotechnology: Its Application On Water Filtration And Remediation

Nanotechnology is being promoted as a technological revolution. It will help solve a lot of problems. It also promises to provide new ways of solving some chronic challenges of developing countries. These challenges include treating malaria and tuberculosis, diversifying energy sources and other applications, and conserving food. There are many nano-materials that are now globally manufactured for various applications:

* Skin care products (cosmetics)

* Structural applications (films, coatings, catalysts, ceramics, and composite metals)

* Biotechnology (diagnostic markers, drug delivery, and bio-sensors)

* Communication and information technologies (optoelectronic materials and nano-wires)

* Environmental technologies (membranes and nano-filtration)

It will also provide promising solutions to improve “point of use” water treatment. This technology will become more effective and efficient about removing all the contaminants in water in order to make it safe to drink. Here are three nanotechnologies for water treatment:

* Nano-sensors – This helps detect contaminants in water.

* Nano-filters with membrane or carbon nano-tubes – This technology filters out contaminants.

* Nano-materials – This helps with the desalination and water pollution remediation.

Mechanical and chemical methods have been used for efficient techniques in the past years. The recent technique is called nano-filtration. It is a relatively recent membrane filtration process that is utilized most often with low total dissolved solid water. This solid water includes fresh groundwater and surface water.

Nano-materials and Water Filtration

The key components of advanced nano-materials, desalination technologies, and water purification are membrane processes. This includes dendrimers, nano-particles, and carbon nano-tubes. They contribute to the development of more cost effective and efficient water filtration processes. Nano-reactive membranes and nano-structured filters are the two types nanotechnology membranes. They are very efficient.

Nanotechnologies for Water Remediation

Many areas in developing countries are really damaged or contaminated with consequent impoverishment of natural resources. This can have a serious effect on human health. Remediation of contaminated water is the process of neutralizing, reducing, or removing water contaminants that threaten the ecosystem productivity and/or human health, and integrity. This is a field of technology that has attracted a lot interest. These remediation technologies can be grouped into categories utilizing biological, physico-chemical, or thermal methods. When these techniques are applied to a certain type of water pollution, they usually work really well.
