The basics of Room Air Conditioners

December 17, 2016 by

movincool1

When it comes to the smaller room air conditioners, there are two types. Split type and the Window/wall units.

Split air conditioners consist of two parts, the indoor unit, and the outdoor unit. The outdoor unit generates the cold refrigerant which is then used by the indoor unit to cool the air. The outdoor unit uses a compressor and a fan cooled condenser to generate the refrigerant which is then sent to the indoor unit through ducting that runs from one to the other and back. The indoor unit runs the refrigerant through a cooling coil. The indoor unit blows air through the cooling coil which is what cools the air. The indoor units can come in the form of a cassette unit, which is usually ceiling mounted. Alternatively, the more common is the wall mounted duct type. Very large split units have floor standing indoor units.

The other type is the window or wall unit. These are much more compact and entirely self-contained units that have no outdoor component. Window units are fitted into the wall and will be supported externally by a metal frame. These are used in older buildings and are not used as much now.  The disadvantages of using these room air conditioning units are their lack of portability and the fact that they cannot be used as a spot cooler.

Although they require regular maintenance and servicing, a rental portable air conditioner can be used during these periods to provide cooling.

The different types of hosting

December 17, 2016 by

rackalley1Written by Rack Alley

The most basic definition of web hosting is the service provided by the large hosting providers to host your website or application on one of or a part of their servers. The infrastructure required to run a data center is expensive and for smaller organizations, using an online web hosting service is the most cost-effective. Here are the main types of hosting in the market today:

Shared hosting

This is the most popular type of hosting because it is also the cheapest form. With shared hosting, several customer accounts are hosted on the same shared server. In some cases, this can be hundreds on the same server. This is the option when looking for la web hosting.

Dedicated server hosting

This is the rental of the entire physical server. It is only different from server hosting Los Angeles because the server is usually the property of the hosting company. This sort of hosting provides a lot of power and flexibility. However, it does require in-depth technical knowledge.

Virtual private server

This is somewhere between shared hosting and dedicated hosting. With this model, a virtual server is rented. It is one of many virtual servers on the same physical server. However, the number of virtual machines running on a single server will be far less than shared hosting. In addition, certain performance guarantees are provided.

Does an e-commerce store require social media sharing buttons?

December 16, 2016 by

securenetshop1Written by Secure Net Shop

One piece of advice always gets repeated again and again when it comes to e-commerce stores: Always have social media sharing buttons. The fact is that 84% of online shoppers use one social network or another. However, several sites decided to test what would happen when they ran pages without the sharing buttons. Would their sales suffer? Would traffic go down? Would there be fewer sales?

In fact, after the test was completed, it turns out that sales increased by 11.9% on the page without the social media sharing buttons. While this might seem counter-intuitive, there are two valid reasons for this outcome:

First is the case of negative social proof. When a site has a high number of shares and pins, that is a strong endorsement and is a positive reinforcement of what is said on the page. Unfortunately, due to a large number of items in most stores, very few product pages will have those sort of numbers. Most will have zero shares and psychologically this translates to poor quality for visitors. Confirm this by doing an A/B test, your web shopping cart will need to support multiple templates.

The other reason is a distraction. When a potential customer is on a page, the primary goal is to get the customer to click the add-to-cart and make a purchase using the e-commerce cart. The problem with additional buttons on the same page is that they take away from that goal. A page with social sharing buttons can have as many as six to seven while a site focused solely on the sale will have two.

The Tell Tale Signs of an Online Shopping Scam

November 3, 2016 by

online-shopping-scam-burglarWith the amount of identity theft today, the online shopping scene can be a scary place. There are a few ways, however, to spot an online shopping scam. Here are a few key things to be on the lookout for.

Users looking for a quick online shopping discount often mistype popular websites, which allows them to be taken to a fake shopping site. Scammers make these fake sites look exactly like their real counterparts, except that they will take your information and run up huge debts. Always double check that you are on the correct website.

Online auction sites are extremely popular for discount online shopping. Sites like Ebay protect their customers with their own insurance. Scammers will often lure shoppers off the website by sending a message claiming that the other buyer has dropped out. Once the shopper sends the money, they never receive the product. Since the transaction took place off the website, the online retailer cannot provide any assistance. Shoppers are advised to always complete transactions through the website.

Scammers will often used classified ad websites to gain personal information as well. Finding a discount online through a classified ad website such as Craigslist is a great idea. Sometimes scammers will attempt to get shoppers to send payment information or a check through email or the mail. This request is a red flag for a scam. Meet the seller in person and use cash. You will be able to see and test the product and pay without sharing any personal financial information.

Using some common sense while shopping online will help keep your information safe. If something appears to good to be true, or you feel uncomfortable with a transaction, follow you’re instincts and leave. You’re probably right.

Costbuys offers a monthly online shopping discount when you order in bulk, and get items shipped direct to you.

Basic guide to setting up a disaster recovery site

September 21, 2016 by

rackalley1Written by Rack Alley

This a basic step by step guide to setting up a cold site at a la data center for a small to medium sized company that has its own application servers in house.

Virtualize

The first step to making a relatively quick (read: hours to days) transition from your office to a cold site with server hosting Los Angeles during a disaster is to virtualize all critical servers in the organization. Ideally, an in-house cluster is the best way to maintain redundancy at the main site.

Backup

Daily backups of critical data and weekly backups of all other data is the next step to put in place. This data can then be restored at the cold site in the event of a disaster. These backups can be taken on tape or disk but need to be stored at an offsite location. Ideally, this would be away from the office.

Replicate

Any critical systems where any data loss cannot be tolerated should be replicated in real time to the cold site. Since the workloads would have been virtualized systems like Hyper-v can replicate to another over the internet every few minutes.

You now have a system where in the event of a disaster, the critical system can be failed over, at which point the restore process from backups can begin. After some DNS and other changes, the cold site is brought up until the main site can be restored.

The advantages of shared web hosting

May 12, 2016 by

3Written by Rack Alley

One of the many choices when it comes to hosting your own website is shared web hosting. Basically, shared web hosting is one server shared amongst hundreds or even thousands of accounts. Each of these accounts can have many sites/domains run by them. While this does sound problematic, and does have its share of issues, it also comes with some benefits:

Cost

Shared web hosting is cheap. You will most likely be paying less than ten dollars a month for an account that lets you host a few domains, websites etc along with some email accounts. For a site starting out it means not having to shell out hundreds of dollars for capacity that will not be used.

Growth

These shared hosting services are limited by the amount of resources you can use. Although they do state that most are unlimited, it is not so and you will eventually have to upgrade when the site grows. But this is not a bad thing. As your site gets bigger, you have the option of upgrading the package in place. You can go to a higher shared package or even go to dedicated or virtual hosting or colocation at an la data center.

Support

Services like la colocation have a lot of flexibility but it also means a lot of more work. You will almost certainly have to do everything on the server yourself. Shared hosting comes with support where a lot of the leg work can be done for you. Certain levels of support are provided and anything additional can be paid for.

A primer of shared hosting packages

May 12, 2016 by

Written by Rack Alley

Choosing a web hosting package for the first time user can be a difficult prospect. There are so many different packages to choose from. The differences between them might not be so obvious. The most popular package you will find on almost any web host is the shared hosting package. They come in many names but are usually the cheapest or one step up from the cheapest. Here is a primer on what to expect from a shared hosting package:

Shared

This reason that these packages are so cheap is because they share a single web server across multiple accounts. In some cases this could mean that a shared account could have thousands of other users on the same server. There are few problems that can stem from that. Firstly, anything that another webmaster on the same la web hosting does can affect your uptime. If a site is suddenly hit with a spike of traffic, it can slow all the other sites on the same server. The same goes for punishments.

Unlimited

These packages also trumpet how they allow unlimited amounts of everything. Unlimited bandwidth, disk space etc. None of this is true. For most customers there are enough resources provided that they would never notice. However, were your site to suddenly become a breakout hit or get a massive amount of traffic, you are likely to be shut down citing some condition. They will then recommend a dedicated server.

Other limitations

There are also some other limitations. The easiest example is security. Now that Google gives additional ranking boosts to sites that use SSL, every site is now looking to get SSL setup. Unfortunately most shared hosts will not be able to give you a dedicated IP that SSL requires. You will need to get proper server hosting los angeles in order to get that dedicated IP.

The Harsh Reality of Radioactive Labeling

April 21, 2016 by

Once commonly used, the hazards have now outweighed the benefits.

Oligonucleotides have been a major contributor in biological and forensic research for years now. Certain applications such as taking on the role of a sequence binding agent to reveal the present of a DNA sequence have provided researchers new information to work off of. In these applications, oligos are labeled for identification purposes. Some of these labels come from radioactive nuclei such as RNA triphosphates. When applied to the oligos, they can be directly added into nucleic acid probes via enzymatic methods like nick translations.

The Hazards of Radiolabeling

However, radioactive labeling does have its caveats. There are a variety of known hazards when handling any forms of radiation. In addition to this, radiolabelling requires there to be careful handling and disposing, which scientists need to closely be wary about. Although this method of labeling does have its advantages in that it provides high sensitivity for the oligo, or the modified oligo, but the expense of working with it makes it difficult to consistently utilize. Therefore, other labeling methods such as fluorescent labeling, colorimetric, and chemiluminescent have been becoming increasingly popular. In most application, radiolabelling isn’t even used anymore. But, every now and then, you’ll find that certain applications require the use of radioactive methods to achieve a breakthrough.

Labeling Requirements

In order for an oligo to be labeled, it must possess certain properties that scientists deem feasible. One of the most common ones would be that the label should be able to attach easily under mild conditions using any type of protocol – regardless of how simple or cheap it is. Another requirement is that the label can be detected at the lowest concentration, otherwise the findings would be inconclusive.

Why PVD is Dominating the Coating Industry

March 31, 2016 by

PVD is commonly used in a variety of today’s industries.

With the numerous amounts of PVD coating equipment available on the market, it’s safe to say that physical vapor deposition is the way to go in terms of coating methods.

PVD is a More Stable Option

One of the more household uses of PVD has to do with the timepiece that you have on your wrist right now. The reason why physical vapor deposition is the preferred method is because of its solid hold on the metal compound. Old techniques, like powder coating proved to only be a temporary solution as continuous contact with it will result in it rubbing off.

Additionally, the deposition process is extremely flexible, which is one of the main reasons why so many industries are taking advantage of this technology presently. Another example that you might not be aware of are the transmission gears and engine parts in racing cars. Because of the reduced friction wear, PVD is has been known to increase the reliability of engines – think about it, over 10,000 RPM’s would require a drastic reduction in friction. This resilience is coveted by high-powered car manufacturers.

The Application of PVD

The application of PVD works in a similar fashion as electroplating would. If you aren’t familiar with electroplating, it essentially involves an electric current as the primary deposition factor. There are plenty of methods for PVD, it honestly depends on the industry. Vacuum coating systems, for example, are used more commonly for watches due to its air tight environment and application necessitates.
