When the heat of the summer sun shines down, it leads to excessive temperatures and causes humidity levels to go through the roof, leading many people to retreat to the safety and comfort of an air-conditioned building. If a home does not have a central AC system, it will most likely cause the interior of the building to become incredibly hot and stuffy and leave those inside uncomfortable. Air conditioning installation in Sylvania OH will help to keep a home cool, and the following is a brief overview of what is involved in the process.

Duct System Installation

As the air is treated by the system, it is then dispersed throughout a network of ductwork, which ensures that each room in a home is maintained at a comfortable temperature. If an existing duct system is not present, then the technicians will first need to install one. They will work with any attic or basement space to run the ductwork, and slimline systems allow them to fit new equipment in an existing structure easily.

Air Handler and Compressor Placement

The next phase of installation involves placement of the air handler and the exterior compressor unit. The air handler is what moves the air throughout a home, while the compressor is what pressurizes the coolant liquid that then cools the air. Though the technician will be somewhat limited by the size of the units, it is essential for the homeowner to make any requests relating to where the items will be positioned before the start of Air Conditioning Installation in Sylvania OH.

Electrical Connections and System Testing

After all of the mechanical components are in place, an electrician will then be contracted to connect the devices to the main electrical panel. In some cases, they may have to install a dedicated breaker to ensure the equipment has an adequate voltage load to operate without issue. Once all of the items are connected and powered on, the technicians will do a complete system check and ensure the system is working as intended.

Installation of a new AC system is a great way to keep a home comfortable all summer long. The experts at A1 Heating and Home Improvement have more than 20 years of experience repairing and installing both commercial and residential systems.

HP are extremely busy working away at their enterprise customer base with their philosophy that one-vendor will fit all, known as Converged Infrastructure . Traditionally, it has been a brave customer who has preferred to go down the one-vendor approach when it comes to satisfying demand for infrastructure hardware. Adopting a multi-vendor approach is seen as a hedge against hardware glitches, but more immediately as a bargaining chip when it comes to pricing solutions.

HP have a great deal of client inertia to overcome, with many customers fearing they will be locked in to the HP solution if they follow the tempting pricing and performance offers. HP counter this concern by claiming they are offering an open architecture solution, but if that is the case why bother trying to tout converged infrastructure in the first instance if is open architecture in the first instance, the HP solution will naturally rise to the surface on merit?

Err. Probably not!

IT solutions are like life insurance they are not bought, they are sold.

This said, running a 100% HP infrastructure will open up a toolset which HP provides which allows for lower CO and TCO (HP networking solutions typically cost 50% or less of major competing solutions). Integrating a hybrid HP and A.N.Other hardware solution leads to degraded network performance because of the limitations of the HP toolset in such infrastructure environments.

There is a clear trade-off at work better performance, lower costs versus undiversified infrastructure base and future lock-in to one vendor (HP).

HP has recently announced its third generation, Matrix blade server management solution which includes server automation and the ability to deploy infrastructure applications, manage performance and security better than before. This all sounds like a great deal and it is, so from an IT decision maker s perspective, what s not to like?

The straight answer is there is nothing you don t need to like, but there is a major competing IT infrastructure strategy which demands you continue with a multi-vendor approach Cloud Computing. Cloud computing is still viewed as having some way to go before it is ready for wholesale adoption, especially by small and midcap businesses, but then again maybe not!

Another obstacle to HP s convergent infrastructure is the amount of legacy hardware floating around. Even where you visit a client who favors one particular manufacturer, it is hard not to find Dell or IBM hardware gathering dust but still showing not the least sign of wanting to quit. Swapping out old, but still functioning hardware is something many IT managers simply don t want to do if it isn t broken, I m not going to fix it and in any event, it s hard for them to see how they can get a better ROI on a piece of new kit, when the existing box had its hard cost sunk years ago.

Probably the biggest obstacle to a single vendor approach is business risk. No-one ever got fired for buying IBM , but then again no-one has ever been fired for diversifying their employer s business risk and achieving a satisfactory ROI. Placing all of a company s infrastructure needs into one vendor s basket is inherently a risky approach, and unless HP truly unlock the infrastructure architecture and ensure 100% open structure, it is probably going to be devilishly expensive to reverse out of that strategy if a customer wants to down the road.

While a forklift is a popular piece of equipment in a warehouse environment, there are certain occasions where they make a simple task more cumbersome and reduce the overall efficiency of employees. An Electric Pallet Jack in Los Angeles is designed to fill in the gap and makes it easy to raise and lower small loads onto and off of shelving units. Before buying a pallet jack, be sure to consider the following items, which will ensure the device will meet a companies needs now and for years into the future.

Device Weight Limit

YouTube Preview Image

One of the most critical, yet overlooked, aspects of purchasing a pallet jack is determining the weight limit of the unit. It is a good idea to weigh a typical load of items that the device will be used to transport to determine the average payload the lift will be handling. Once the requirements are identified a company will then be able to select a unit that will safely and quickly tackle any job thrown its way.

Self Propelled Units

An Electric Pallet Jack in Los Angeles is either manually moved or is equipped with a motor that aids in the transportation process. While self-propelled lifts are a great option, they usually require additional maintenance and come with a higher upfront cost. If the weight of items being lifted will exceed 100 pounds, most manufacturers recommend selecting a unit with a motor that will reduce the likelihood of employee injury and reduce the time required for warehouse tasks.

Space Constraints

Another important detail to consider is the size of the warehouse where the device will be used and stored. Devices that are designed with self-propulsion are much larger and may be hard to maneuver in small spaces. It is also necessary to determine the type of electrical connection that is required for charging and make sure that one is readily available and that there will be adequate room to store the pallet jack without creating a safety hazard.

A pallet jack is an invaluable tool for a warehouse environment.

Top Ten Linux Interview Questions

by

Dwayne Genoveva

By having the perfect answer the Top Ten Linux Interview Questions you can ace any Linux Interview. I’ve been working as a Freelance Linux Consultant for the past seven years. Over all those years, I’ve been in more than a dozen of roles, attended tens of face-to-face interviews and probably close to a hundred of phone interviews.

YouTube Preview Image

Few painfully obvious things struck me during my time:1) Your encyclopedic knowledge of Linux is far more likely to get you a job than your actual problem solving skills.2) Technical questions asked during phone interviews and even face-to-face interviews tend to be fairly basic. Employers rarely ever go into detailed technical scenarios.3) You will be asked almost the same technical questions at almost all interviews you attend.This means that even if you feel your knowledge of Linux is limited at the moment, make sure to know detailed answers to the following Top Linux Interview Questions and you double your chances of getting the job.You are virtually guaranteed that at least half of the questions asked will sound very similar to the following (I tried to provide the simplest ways to answer these as well, for full answers please refer to http://www.linuxinterviewquestions.com):1) What is the difference between TCP and UDP?The basic difference is that TCP establishes a connection before sending data and this allows it to control the dataflow and guarantee that all packets get delivered. UDP simply chucks datagrams onto the wire and if some get lost or arrive in bad order there’s no way to request a resend. However UDP has low network overhead so some services such as DNS resolution, SNMP, DHCP, RIP and VOIP use UDP for its speed and any errors are usually dealt with on the application layer rather than network layer.2) What is the TCP hand shake?TCP requires three packets to set up a socket connection, before any user data can be sent. This is called the tree way TCP handshake. First the requester sends a SYN packet and expects a SYN-ACK packet, to which the initiator replies with ACK packet plus the first chunk of user data. From there on the TCP connection is established and two sides exchange user data using features such as message acknowledgment, retransmission and timeout.3) How does DNS resolution work?A client application requests an IP address from the name server usually by connecting to UDP port 53. The name server will attempt to resolve the FQDN based on its resolver library, which may contain authoritative information about the host requested or cached data about that name from an earlier query. If the name server does not already have the answer, it will turn to root name servers to determine the authoritative for the FQDN in question. Then, with that information, it will query the authoritative name servers for that name to determine the IP address.4) What is an MX record?MX record numerically ranks the mail servers you would prefer to receive email for a domain. The MX record with the lowest number is preferred over the others, but you can set multiple email servers with the same value for simple load balancing.5) Describe Linux boot-up sequenceBIOS reads the MBR where Boot Loader sits, Boot Loader reads Kernel into memory, Kernel starts Init process, Init reads inittab, executes rc.sysinit, the rc script than starts services to reach the default run level and once this is done the last thing that gets run is the rc.local script.6) What is an INODE?All files have its description stored in a structure called ‘inode’. The inode contains info about the file-size, access and modification time, permission and so on. In addition to descriptions about the file, the inode contains pointers to the data blocks of the file.7) How do you search for a pattern and than replace it in an entire file?Using Sed or in Vi editor the search usually involves character ‘s’ slash the pattern to be searched, slash the pattern to replace it with, slash ‘g’ which stands for entire file.8) How do you list and flush all IPtables?Using the iptables command with -L switch first to see all the rules currently present in memory and than -F to flush them.9) How do you list compiled-in Apache modules?Run the httpd daemon as a command with -l parameter.10) What is a zombie?Zombie processes can be identified in the output of ‘ps’ by the presence of ‘Z’ in the STAT column. Zombies are child processes whose parent process diedwithout reaping its children. Zombies can’t be killed with the usual KILL signal.

So there you go. This is the technical part of your Linux interview handled. Don’t ask me why but these are the top most repeated Linux questions at interviews. If it is recruiters lack of creativity or laziness. It is simply a fact. If you want to make absolutely sure you are 100 percent crammed for your all-important upcoming interview, I highly recommend you spend few minutes browsing
