Could You Work in the Cloud?
I'm sure you've heard how some people fear that the cloud computing phenomenon will cut jobs in different industries.
While it is unclear yet how many jobs will actually be 'transformed' with the introduction of the cloud, multiple studies have shown that the same cloud industry will actually generate jobs.
One of those recent studies, which is a joint report by 'Oxford Economics', 'Goldblatt McGuigan' and 'Whisple Cloud', have even stated that this new technology will generate 16,000 more jobs in Northern Ireland alone.
Personally, when I think about such figures, I just can't help but wonder what kind of jobs could those be. And, like most people, I've come to the natural conclusion that those jobs will most likely be IT related.
However, is this actually the case? Let's have a look at the kind of jobs that the cloud-computing industry could generate:
IT engineers: well, this is an obvious one. After all, the Cloud is directly related to Software-as-a-Service, or Platform-as-a-Service or even Infrastructure-as-a-Service.
However, beyond all of this, there are lots of developers working behind a single cloud-computing offer. Indeed, if you only consider the software in itself, it needs hours of coding and testing before it can be delivered as a complete product. As well as the core development of the software, don't forget the 'mobile developer' whos task is to make the product viewable through apps or mobile versions of the website. In the same technical field, we can also include lots of System Administrators and Network Administrators who will make things work smoothly, with an availability which is defined on the Service Level Agreement.
Customer Support team: At this stage, there can be many different levels of support, thus many different roles within a Cloud based team. The cloud being availed to people from different places and countries, the chances are that support could be needed in different languages, and on different time-zones.
The Sales team: Most cloud-computing business models have an in-house sales team, but they also rely heavily on resellers that will do the demos as well as sell-on the Cloud solutions. This reseller's business model allow cloud computing to generate a lot of jobs since the same system can be sold in different ways, and from different locations thereby making geo-segmentation easier.
Training and consulting: as is common with any new technology, the introduction of cloud-computing solutions will require some change management as well as training to end users.
And last but not least, the cloud in itself can enable budding entrepreneurs to create new ventures. I've already written previously about how the cloud can help make a difference to the solo-preneur - as a reminder, we said that cloud computing is the 'magic' solution that allows the solo-preneur to focus on their business while 'outsourcing' their IT solutions to the cloud: this could include book-keeping systems, customer relationships management as well as communications (e-mail, calendar, contact... ).
This list is surely not exhaustive, and I invite you the reader to add to it or by all means, delve into more detail on some specific points. After all, your contribution may also inspire some other people to consider the advantages of cloud-computing for their business.

HDMI Matrix - An Easy Solution For Connecting Multiple Devices
What do you do when your high-definition television set has only one HDMI connection, but you have several HD components that you want to connect? In today's digital age people are hungry to have different components to capture or view videos or pictures, watch the latest 3D movie release, play an xBox game or revisit of the baby's first birthday. The problem is that many older high-definition televisions are designed with a single HDMI port. In order to resolve a problem where there are more connections than HDMI ports, you use a HDMI matrix.
The problem with having so many high-definition gadgets is that many HDTVs have a single port. Well, there is another problem: You've run out of space to store all this stuff in your entertainment center. The good news is that using an HDMI matrix switcher, solves both problems. Buying an HDMI switch won't send you to the poorhouse either.
An HDMI matrix acts as a hub for multiple source devices and then relays the audio and video signals to a receiver, typically an HD television. Some HDMI switch devices allow you to switch between the components using a remote control or manually pushing a button on the unit. More advanced HDMI switch devices actually automatically change over to a component when it is powered on or when another is shut down.
The basic implementation allows several HD inputs and outputs which can be conveniently selected in any combination. If you have to extend the distance between the switch box, HD components and the television then choose a more advanced HDMI matrix unit with the ability to transmit high-definition signals over a CAT5/6 cable. This cable is very lightweight and flexible making it an ideal solution for stringing through ceilings or walls. Some HDMI matrix switchers allow you to flip between different components and even select another combination of devices while the first selection is active.
There are a number of different HDMI matrix models the most popular supporting 3 inputs and 1 output. That means you can connect 3 HD devices and switch between each to view on a single output, your television. There are several other input/output configurations available including 4x2 (4 inputs/ 2 outputs), 4x4, 8x8 and even 16X16.
You don't have to be a high-end technology business to benefit from these solutions. Small businesses and the home gadget experts benefit from using HDMI matrix units offering simple and reliable HDMI distribution.

Consumerism of IT and Its Impact on Enterprise Mobility Solutions
During the early days of enterprise mobility solutions, there were only a few solutions capable of providing mobility to business users and the functionality afforded by these solutions was also limited to only a few activities such as checking of emails, looking up contact information, creation of documents on portable devices etc. During the initial period, enterprise mobility like many other emerging trends globally featured a needs-based approach, which led to the creation of apps as and when required by the users. The model was definitely not without its merits; however, a major issue resulting from the creation of such needs-based apps was the lack of user-friendly features as well as the minimal use of graphics in developing such apps. Things however never remain stagnant in the technology market and the enterprise mobility market changed almost overnight with the introduction of new platforms such as Android and iPhone/iOS, which featured a higher degree of user acceptance than ever before. The rapidly changing conditions of the enterprise mobility market also led to the introduction of a new trend in business- CoIT (Consumerism of IT).
In current literature, a proper definition of CoIT may be lacking, however, the basis of CoIT is much more easily understood. As smart phone adoption for personal use grew with the advent devices, which were designed specifically for individual use such as the iPhone, the iPad and various Android-based devices, many enterprise users (initially mainly senior management) wanted to be able to use their personal devices for doing company work on the move. The main reasons for this trend included the availability of various user-friendly apps and features as well as the superior design and functionality supported by these devices. The central issue for CoIT is the user's desire for apps and devices which are easy to use, powerful as well as elegant. As such an experience was not possible as the previous generation of mobile devices and apps, the market changed seemingly overnight and CoIT emerged as a driving factor in the enterprise mobility market.
These recently launched "consumerised" apps and devices provide users with an intuitive and compelling experience, which increases the overall acceptance of available software and hardware resources provided to the user. The new solutions are almost an exact opposite of traditional systems, which even though efficient, mostly featured a slow, complex and often monotonous interface. As the old interfaces did not provide a compelling user experience, it was only natural that the new consumer-friendly apps were easily accepted by users over the enterprise mobility apps and devices, which were available earlier. The major benefits from a user perspective of these new apps are the reduction of monotony and complexity in carrying out enterprise-related tasks. From the perspective of an enterprise, the benefits include further improvement of organization-wide productivity- a cornerstone of introducing mobility solutions for an enterprise.
Repercussions of the CoIT Trend
BlackBerry to Lose Enterprise Mobility Market Leadership
One of the first market-wide repercussions after the emergence of CoIT trends was the increased acceptance of emerging platforms such as Android and iPhone/iOS platforms over the mobility market leader- RIM's BlackBerry OS. Overtime, the market share of BlackBerry in the enterprise mobility market has been significantly eroded and more mobility users are shifting to alternative platforms in order to maximize the benefits derived from the use of enterprise mobility. Current short-term predictions by industry experts suggest that within the next 2 to 3 years, the BlackBerry OS will no longer hold majority market share in the mobility market.
Enterprises to Support Multiple Mobility Platforms
Though the senior management was among the first people to ask their enterprise IT departments to initiate support for their new devices, other employees followed suit. IT departments soon realized that it was not possible for them to enable every device on their existing platform and in many cases they decided to provide support for multiple platforms. Currently, a majority of enterprises with emphasis on mobility provide support for two or more enterprise mobility platforms in order to support a wide range of mobility devices.
The Introduction of BYOD
As the number of user-owned devices increase in the organization's network, more and more companies are expected to implement the BYOD (bring your own device) trend to decrease overheads related to buying and maintaining multiple mobility devices for use by employees. This has been one of the key changes in enterprise mobility market, which was caused by the Consumerism of IT trend. The introduction of BYOD has been instrumental in expanding the market as more and more companies have found it necessary to support multiple mobility platforms and devices due to the exponential increase in mobility devices used by employees. However, the BYOD trend has also caused enterprises to seriously consider the possibility of breach in data security. BYOD led to companies taking more precautions to ensure the security of sensitive information. Some of the newer trends designed to provide greater security to organizations all over the world include remote wipe and container techniques.
So, what's next?
The technology and devices market changes so rapidly that it is practically impossible to determine what course the mobility market is going to take in the future. However, one thing is for certain, the CoIT trend has already changes the way mobility is provided in enterprises all over the world and such change is an ongoing process, which will continue to bring about further change in various markets including the enterprise mobility market.

I'm Paranoid (About Backups)
Yes, I'm paranoid. So should you be. Backups are my passion. "Do your backups" is my mantra.
"Why?" I hear you ask. That's easily answered. I'm a computer troubleshooter and web designer. I spend a lot of time tending to poorly computers. I don't have a workshop, I work in my clients' homes or offices, so poorly computers are usually accompanied by their unhappy owners.
We've all been there - your computer starts working more slowly, it won't turn off properly, it won't turn on properly, it freezes, strange boxes start popping up. I treat my own computer as if I'm an over-anxious mother. The instant it so much as hiccups I'm scanning it with Malwarebytes, Superantispyware and CCleaner. Most of my clients don't do this - they just learn to live with their computer's strange behaviour - which slowly deteriorates until the time comes when it won't turn on, or won't unfreeze, or won't connect to the internet. Then they phone me. Often in a panic.
What would YOU do if you woke up tomorrow and found your computer wouldn't turn on? Or found it had been stolen? Or there'd been a flood or fire in your office?
Computers can be replaced - as I'm typing this I'm on my second new computer in as many months. The old one's screen has failed. The first replacement failed after a few weeks and had to be replaced. What did I do in the interim? I used a friend's computer - I have easy access to all my data online, in the "cloud".
Data can't be replaced. Your precious photos, documents, videos are irreplaceable. You can't nip to the local store and buy a replacement set of family photos. This is where backups come in. Backups are good, you can't have too many. You can, however, have too few.
I meet many people who claim they store their backups on an external hard drive or on memory sticks. Just yesterday I rescued data from an ageing computer that had frozen. Its owner assured me it backed up regularly. When I asked him where to, he had no idea. Do you want to guess where? It was set to back-up to an external hard-drive. Not a bad idea - except the external hard drive had spent the last 3 years living in the roof of his garage. Yes, really. The last backup was 3 years old.
The moral of that part of the story is this: If your computer backs up automatically make sure that
a) You know WHERE it is storing its backups, and
b) That it is actually doing those backups.
Many backup programs simply store a complete new backup each time, I see many hard drives that are full of old backups, have run out of space and haven't been able to store a new one for ages.
Is this happening to you? If your backups are being stored one after the other to a memory stick, DVD, hard drive, etc, check that your backup medium isn't full to capacity with old backups. If necessary, delete all but the most recent to free up space.
There are two downsides to all these backup methods. One is that your backup medium needs to remain connected to your computer. The other is location.
Location? Yes. Where do you store your backup medium? With the computer, right? Suppose your computer is stolen, lost, damaged by fire or flood. What will happen to your backups?
Can you see where this is leading? Cloud storage. Online backups. I couldn't live without mine. I wouldn't sleep at night without mine. When my computer failed just a few weeks ago, I didn't panic. As I said above, I was able to access all my data from friends' computers. It was all there, safely stored online.
Most online backup services can be set to backup to a schedule or, like mine, be set to back up automatically whenever the computer is idle. As long as you have a good enough quality internet connection, you can sleep easily, knowing that your data is safe. I can see at a glance which files have been backed up and which are awaiting backup.
If you decide to join a cloud storage service, just be aware that your initial backup could take a few days - depending on the upload speed of your internet service. Mine took two whole weeks of leaving my computer turned on 24 hours a day.

HDTV Refresh Rates: 120 Vs 240Hz Vs 600Hz Plasma
A screen's refresh or frame rate is referred to as the speed at which it switches images one after the other. Anything recorded on visual data is actually divided into pieces of images that are chronologically pieced and timed together to give the illusion of motion. A simple way to prove this fact is by looking at old film reels.
Most screens refresh at around 30Hz (or 30fps if it's a video media), which means that the screen flashes 30 still images in one second. The generic standard of most HDTV's is set at around 60Hz, but many more advanced models are capable of pushing this rates to 120Hz, 240Hz and even 600Hz.
Why care about the refresh rate?
Why is it important for some people to have higher screen refresh rates? The answer lies in image fluidity. The increase in flashed images when refresh rates go up usually results in increasing the detail and sophistication of any kind of movement, thus making it look a lot more fluid. This provides added depth to anything that you are watching on your HDTV. Not only would you be able to see everything in clear detail, as you will also see each micrometer of movement in any direction very clearly. Also, another good benefit of higher screen refresh rates that is connected to increased movement fluidity is the apparent elimination of screen lag.
And now for a simple comparative analysis about some of these refresh rates:
120Hz versus 240Hz - 120Hz is probably considered as the most standard of all of the higher refresh rates, because it does not veer too much from the HD standard 60Hz (although it is still double the amount). 240Hz on the other hand, may be a little bit too much for the average viewer although it is undeniable that those kinds of refresh rates would still create superbly fluid images. When it comes to choosing which is better between the two though, practically we would have to say 120Hz.
Higher refresh rates usually only interpolates video data in order to produce additional frames. What are you going to do if you need to pull a 1080p MP4 file that is only set at 60Hz? The image on the HDTV would probably produce a more fluid quality as it attempts to transform it to 240Hz, but it would be too unnatural for you to watch properly.
240Hz versus 600Hz - if 240Hz worsens the problem of overflowing image fluidity, how about trying to crank up the refresh rate 10 times than that of the standard one? 600Hz HDTV's aren't exactly that bad, I mean, they are always marketed as the best kind of HDTV that can produce the "most fluid image that you have ever experienced", but then again, the issue lies with practicality. 600Hz might totally eliminate any sign or trail of motion blur in the video, but it would drastically alter its image quality. Depending on the one observing the change, the sheer unnaturalness of image could be quite annoying.
In fact, there are a substantial number of people that quickly became unsatisfied with higher refresh rates. They named the unnecessary motion fluidity given by these HDTV's the "Soap Opera effect". Anything that has their refresh rates drastically altered would seem to look like it was filmed using cheap and economic studio cameras. And that is only when they started watching everything in 60Hz (yes 60, not yet 600).
Most screens refresh at around 30Hz (or 30fps if it's a video media), which means that the screen flashes 30 still images in one second. The generic standard of most HDTV's is set at around 60Hz, but many more advanced models are capable of pushing this rates to 120Hz, 240Hz and even 600Hz.

Higher refresh rates usually only interpolates video data in order to produce additional frames. What are you going to do if you need to pull a 1080p MP4 file that is only set at 60Hz? The image on the HDTV would probably produce a more fluid quality as it attempts to transform it to 240Hz, but it would be too unnatural for you to watch properly.
240Hz versus 600Hz - if 240Hz worsens the problem of overflowing image fluidity, how about trying to crank up the refresh rate 10 times than that of the standard one? 600Hz HDTV's aren't exactly that bad, I mean, they are always marketed as the best kind of HDTV that can produce the "most fluid image that you have ever experienced", but then again, the issue lies with practicality. 600Hz might totally eliminate any sign or trail of motion blur in the video, but it would drastically alter its image quality. Depending on the one observing the change, the sheer unnaturalness of image could be quite annoying.
In fact, there are a substantial number of people that quickly became unsatisfied with higher refresh rates. They named the unnecessary motion fluidity given by these HDTV's the "Soap Opera effect". Anything that has their refresh rates drastically altered would seem to look like it was filmed using cheap and economic studio cameras. And that is only when they started watching everything in 60Hz (yes 60, not yet 600).
IBM Information Server 8.X (DataStage): Parallel Transformer Stage Variables And Properties
DataStage: What is Transformer Stage?
DataStage provides several stages to load the data into the data warehouse or data marts. The stages classified into General, Database, Developement and Debug, File, Processing, Real time etc. and the transformer stage is a processing stage.
Local Variables:
You can declare and use your own variables within a Transformer stage. Such variables are accessible only from the Transformer stage in which they declared. Since these variables are local to the transformer, the name local variables.
The uses:
The values assigned by expressions.They are used in expressions which define an output column derivation.Expressions evaluating a variable can include other variables or the variable being evaluated itself.
Advantageous of stage variables:
1. Same part of an expression used in multiple column derivations.
For example, IF (DSLINK1.col1 [1, 3] = "001") THEN { statements evaluated here} used in multiple output column derivations, the expression evaluates for each column that uses it. Use the stage variable by moving this substring calculation and the substring evaluates just once for every input row.
2. Where an expression includes calculated constant values.
A column definition might include a function call that returns a constant value, such as: Str(" ",20).This returns a string of 20 spaces. In this case, the function would be evaluated every time the column derivation is evaluated. It is more efficient to calculate the constant value just once for the whole Transformer.
Use the stage variable to use this function. This case, the function would still be evaluated once for every input row.
Assign the initial value from the Stage Properties to the stage variable and leave the derivation empty. This way, the function evaluated only once for whole transformer processing.
3. Where an expression requires a type conversion and used as a constant, or used in multiple places
System variables
WebSphere DataStage provides a set of variables containing useful system information that you can access from an output derivation or constraint.
Name Description:
@FALSE The value replaced with 0.
@TRUE The value replaced with 1.
@INROWNUM Input row counter.
@OUTROWNUM Output row counter (per link).
@NUMPARTITIONS The total number of partitions for the stage.
@PARTITIONNUM The partition number for the particular instance.
Transformer stage: Input page
Partitioning tab:
The Partitioning tab allows you to specify details about how the incoming data partitioned or collected when input to the Transformer stage. It also allows you to specify that the data should be sorted on input.
By default the Transformer stage will attempt to preserve partitioning of incoming data, or use its own partitioning method according to what the previous stage in the job dictates.
In The transformer stage, the stage tab allows to set various properties in the General like Execution mode, Preserve partitioning, Advanced tab, Triggers tab etc.
