Internet: When it works the way it’s supposed to, middleware disappears into the background of an organizational infrastructure. Publish and subscribe (P&S) middleware, which occupies the middle ground of the middleware world, is no different.

Sometimes referred to as pull software or smart-push software, P&S middleware enables information consumers to subscribe to particular messages (sometimes known as data events, to distinguish them from e-mail-type messages) while making it easy for information producers to publish data events. P&S products can keep a lid on network traffic, even when there’s lots of data and many subscribers, by using message routers and multicast transmission to distribute information.

I examined three leading P&S solutions: Open Horizon’s Ambrosia, Talarian’s SmartSockets, and Tibco’s TIB/Rendezvous. These products typically become an integral part of a large organization’s computing infrastructure, using many different platforms, networks, and architectures, as well as different applications.

Choosing a tool is more than a matter of finding one that helps you build what you want. Most middleware tasks can be handled by most P&S solutions, but some just work better and are easier to implement than others for a particular application. Architecture, programming API, level of delivery reliability, and availability of security features, including

For the common user, computer data recovery is a hard term to understand. A regular computer user who has not invested his time to understand what computer data recovery is will find a lot of difficulty whenever disaster strikes unless they have a backup plan. Computer data recovery is that process that helps you get back the data which you have lost. It can take a few hours to days depending on the amount of damage caused to your hard disk.

Hard driveLoss of data in a computer can be a result of many things. One, natural disasters such as earthquakes, floods, thunderstorms and fires may lead to damaged hard disks. When faced with such a crisis, you should not try to sort it out; instead leave it and let the experts handle it.

Another cause for loss of data can be viruses. When your computer is directly connected to the internet, you should have an antivirus which is strong enough to protect your machine from these viruses. Also, this kind of antivirus program should be one that is updated on a daily or weekly basis to ensure maximum protection. Corrupt hard disks are also a cause of data loss in a computer. To avoid this, one should use disks that are clean and up to standard.

To any organization, data is considered one of its most precious assets, alongside the human workforce. As such, many organizations invest heavily in ensuring that the data is kept safe and secure, and that its integrity is not compromised in any manner. A damaged hard drive can be brutal. This should be the case for every company, but it is hardly ever the truth. In many cases, businesses will adopt a reactionary stance; waiting for disaster to Read on »

raid-server-diskThe answer is in the negative. When you say layman, it means somebody who has no formal training in as far as RAID 5 recovery is concerned. In its simplest sense, it refers to ordinary people who rely on Do It Yourself instructions to do pseudo technical jobs. Given that definition of a layman, it may not be impossible to start with the recovery process but I bet the completion and its success would be the one that would be impossible to accomplish.

Any kind of RAID recovery requires enough training in hardware and software troubleshooting. The process requires the manual retrieval of images from parity lines for restoration into the original array of disks. If your Raid 5 system is composed of 3 disk drives, one of these will be utilized for the parity line. That utilized drive will store all the images that will come in handy once failure of the other operating disk drives occurs. The images from the parity lines will be arranged and stacked up together to form a sequence which will lead to full data restoration. The process is never easy. Even IT experts sometimes fail to retrieve the images and to restore the data that is lost.

More About RAID
“RAID 5 or Redundant Array of Inexpensive (or Independent) Disks that have been built in a level 5 volume set is a combination of hard drives that are designed for data to be written throughout three or more additional drives. In this kind of RAID, additional data is written to the disk in order to let the volume to be rebuilt in case a single drive fails to function. In case a single drive fails to function, the RAID 5 recovery will do its job to retrieve the data by replacing the damaged disk to a new one. The parity data will be used to rebuild the contents of the damaged disk.

Doing the RAID 5 recovery can be done in two ways. You can use the hardware or the software configuration. The difference between the two is that the hardware configuration uses a physical controller, which is usually built in the motherboard, that is responsible for the reading and writing of data within the hard drives in the volume; whereas, the software configuration uses a standard drive controller and the software utility manages the drives in the volume. Professional RAID 5 recovery is advantageous because in cases where a disk fails or has been corrupted; the data can often be retrieved through the other disks in the volume.

For the past decades, computer experts have been dreaming up ways of how to store high volumes of data without getting too expensive. Thus, they were able to find a solution in the form of RAID. It is a system developed where low cost hard drives are put together to give or provide high quality storage of data, excellent performance, and reliability over the older storage systems. Typically, there are three forms of RAID used for desktop computers. RAID 5 is the most powerful RAID form used in the desktop computer system. But a RAID 5 array may break down and there may be a possibility that data may be lost if not taken care of immediately. Once it happens, RAID 5 recovery is needed so as not to prolong the damage and for the other disks no to be affected.

The RAID 5 recovery process is somewhat complex. It is because finding Read on »

Do you need your portable hard drive to be fixed? Well if you find a highly qualified specialist in hard drives, they can make this happen for you in no time and even ensure that they retrieve all your information without losing data from the drive. Though they might be slightly expensive, they will surely do a commendable job for you. Most of these external hard drive recovery geniuses even give you a warrant so that in case the hard drive they have fixed experiences some problem before the end of the warranty, then they will rebuild it for you for free.

Most people believe that finding a cheap external hard drive repair specialist is hard. This at times is true but only if you do not really know where to find one. Most of the experts in disk drive repair are found online, of course. Here you can get a good look at their services and choose from the one you think you can trust. Once you are able to trust them, only then can you give the data recovery service your external hard drive, but still make sure you make regular checks on their progress. In cases where they stop communicating with you, you should get in touch instead, as these shops are typically quite busy.

problemsFinding a skilled online external hard drive repair engineer at times is very tricky and requires one to be very keen.

Fashion industry officials are opening their wallets wide to back their favorite candidates and parties leading up to November congressional and state elections, after which stricter rules for campaign contributions could likely be in place.

Among retailers heavily into the business of 2002 campaign giving is retail giant Wal-Mart Stores, which is demonstrating how it also dominates general merchandise, department and apparel specialty stores in amassing a political war chest.

Halfway through the two-year congressional-election cycle, the Bentonville-Ark.-based chain’s political action committee collected $630,272 in donations from Wal-Mart store managers, executives and workers, as well as others outside the company. Of that amount, Wal-Mart gave $589,480 to mostly Republican candidates and activities, according to year-end 2001 Federal Election Commission reports.

fnppmwAt this pace, Wal-Mart by the fall will likely outpace its $694,032 in contributions made during the 1999-2000 election cycle, which in turn surpassed the $159,575 given by the company from 1997-1998. The increase in political spending reflects “a growing realization in the last few years that Wal-Mart needed to be more politically active” and help like-minded candidates get elected, a company spokesman said.

“There are a rising number of issues at the local, state and federal level that affect

hdrHDD recovery is basically retrieving lost data on a hard disk drive. Usually, the disk was exposed to physical damage, which could mechanically spoil it. For example, if a laptop fell on a hard ground, it may encounter hard disk damage.

Meanwhile, corrupt files could also damage the hard drive: erasing all its data. One could manually retrieve the data or use special software designed to do the work. For manual retrieval of data from a damaged hard drive there are costs involved. Software developers also charge highly for their products and services. However, the best thing is that HDD recovery is the best thing in panicking situation especially where one fears of totally losing their data.

The lesson therefore is to take good care of the computer. One should not put it in compromising positions as its hard drive might get damaged easily and cost heavily. A backup is very necessary for every document a computer user considers useful. Just because of the high availability of HDD recovery one should not be careless to lose their data as it is sometimes impossible to retrieve the data especially where the hard disk is physically damaged – some of its components have broken down completely.

Why You Need HDD Recovery

Hard drives are finely tuned machinery where the important data and files are stored for use when necessary. These data and files can be lost due to failure of hard drive functions. The failure may be on account of various reasons, such as malfunction of power up systems, dropping, hitting, excessive heat or other external Read on »

With a certificate protocol, some Java applets and ActiveX components receive special privileges. For the corporate developer, this arrangement makes sense. You can design a system where certain applets perform file I/O, for instance. (In the case of importing a file, this ability allows a new Java-based system to mimic an older client-server application.) You might even consider caching data locally to improve performance.

problemsAs you might expect, Microsoft has been innovative in letting developers gain access to native or legacy code from within Java applets and ActiveX controls. These options usually involve making a choice, particularly with running Internet Explorer. (In the worst case, if it bothers you, it involves running a Win32 system of some sort.)

A reasonable counterargument is that corporate developers make such choices all the time. We invest in a technology infrastructure–hardware and software–and can actually define minimum requirements to run on an intranet, such as operating systems and browsers. Writing 100 percent pure Java–with no access to legacy code–is a fine ideal, but many of us have legacy systems to migrate to and maintain.

One of the niftiest tricks of Microsoft’s Java Virtual Machines (JVMs) (which can be disabled, of course), which

Not since the height of the Gingrich revolution in 1995 have Republicans been as strong as they are now. President Bush has been more popular for more weeks than any president since they started taking presidential-approval polls — indeed, for longer than his top aides expected at the start of the war. Eighty-five percent of the public approves of the job Bush is doing, with about 60 percent “strongly” approving. People trust him over Democrats not just on foreign policy, but on economic policy. In a number of polls, his popularity is rubbing off on congressional Republicans. So the question on the minds of Republicans and Democrats alike is: Just how long will it last?

Polls come and go, and only a fool would try to predict where they’ll be this coming November, let alone in November 2004. But polls are not the only reason for Democrats to worry. And their situation could well get worse.

What drives Democrats crazy is that before September 11, they thought they had the Republicans where they wanted them: playing defense on health care, campaign-finance reform, and the environment. The recession was also bound to hurt the GOP.

When the attacks happened, Democrats were

Unity or no national unity, this question is on the brains of Rep. Richard A. Gephardt, Sens. John F. Kerry, John Edwards, and Joe Lieberman, and all the others who were potential candidates before September 11. But it’s only on the tongue of Sharpton.

On Senate Majority Leader Thomas A. Daschle: “His position in Washington could be used against him.”

On Edwards, who made his fortune as a trial lawyer in the area of personal injury: “I would want Edwards to run, because he [was] a lawyer who represented victims and made a lot of money. I fought for victims all my life and didn’t get paid.”

On Kerry: “I know who he is, but I don’t know how much of a profile he has in the black community.”

On Gephardt: “I’ve met him; I like him; I think he’s a decent guy. But he’ll be leading the charge to take over the House. How is he going to then turn around and say that he should be President?”

nmianAnd, of course, on himself: “It was Harold Washington’s race in ’83 that energized Jesse Jackson’s presidential race of ’84. In many ways, Freddy could be the same person for me.”

Although I am an opponent of excessively high tax rates, both because they can be unfair and because they can impact on our efforts to protect and support our families, there is ideological tunnel vision in this right-wing, libertarian Republican position.

Yes, success is in part the result of hard work and ability, the rewards of which are deserved. But I know that my individual success is also in part the result of good luck and support from others. Even more important, it could not have been achieved in the absence of the society of which I am a member. I have an obligation to respond more than proportionally because I have profited more than proportionally.

tterRecognition of such obligation is part of what I was taught as a child. It is essential to being a mensch: literally being a “man” but figuratively being a “human being.” I admit that I wish my top tax rate were lower. But when the recent tax reductions were enacted, I would have voted instead for decreases in the regressive Social Security taxes for lower income brackets. These are the brackets in which rent is a huge burden and in which medical and dental
