Why Do We Need Software Engineering?
RecoverySoft / August 14, 2018

To understand the necessity for software engineering, we must pause briefly to look back at the recent history of computing. This history will help us to understand the problems that started to become obvious in the late sixties and early seventies, and the solutions that have led to the creation of the field of software engineering. These problems were referred to by some as “The software Crisis,” so named for the symptoms of the problem. The situation might also been called “The Complexity Barrier,” so named for the primary cause of the problems. Some refer to the software crisis in the past tense. The crisis is far from over, but thanks to the development of many new techniques that are now included under the title of software engineering, we have made and are continuing to make progress. In the early days of computing the primary concern was with building or acquiring the hardware. Software was almost expected to take care of itself. The consensus held that “hardware” is “hard” to change, while “software” is “soft,” or easy to change. According, most people in the industry carefully planned hardware development but gave considerably less forethought to the software. If the software…

SEARCH Function and FIND Function in Microsoft Excel
RecoverySoft / August 14, 2018

There are two very similar functions in Excel to look for data inside of cells matching parameters that you dictate: SEARCH and FIND. There are so similar, in fact, that one wonders why have two separate functions that perform virtually the identical results and are identical in the construct of the formula. This article will discuss he one, basic difference. SEARCH Introduction The SEARCH function is a way to find a character or string within another cell, and it will return the value associated with the starting place. In other words, if you are trying to figure out where a character is within the cell that contains a word, sentence or other type of information, you could use the SEARCH function. The format for this function is: =SEARCH(“find_text”,”within_text”,start_num). If, for example, the word “alphabet” was in cell C2, and your model needed the location of the letter “a” in that cell, you would use the formula =SEARCH(“a”,C2,1), and the result would be 1. To continue this simplistic example, if you were seeking the location of “b” in the word, the formula would be =SEARCH(“b”,C2,1), and the result would be 6. You can also use search on strings of characters. If,…

How to Spy on a Computer Without Anyone Knowing
RecoverySoft / August 14, 2018

If you need to know how to spy on a computer, I’ll tell you right now that it’s with software. But not all are created equal… some can spy on certain activities, but not everything. What’s more is that most do not do so invisibly – and this is the key thing here. Invisibility and stealth are paramount to the success of monitoring computer activities no matter the reasons. Why? For example, this is not how to spy on a computer; if you’re trying to keep an eye on your kid while he’s online to make sure he doesn’t go off on some crazy bestiality porn site, it would do nothing if there’s some blinking fireball of an icon pulsating in the system task bar. He’ll clearly know he’s being watched, and go off to a friend’s house to check out some porn on his friend’s computer. Obviously, that is not how to spy on a computer at all. In order to do so effectively, you absolutely positively need stealth. You need to be invisible, or it just ain’t happening, period. For this reason, when you seek out some software to monitor computer activities, it’s got to run silently and…

7 Ways to Prepare Your Data Center for a Natural Disaster
RecoverySoft / August 14, 2018

No one wants to think about a disaster crippling or even destroying their data center. But even as hurricane season has ended for Atlantic and Gulf Coast states, wildfires are raging in Southern California. Earthquakes are an ever-present danger. Disaster planning is moving higher up in the priority list for many data center managers. Disaster recovery (DR) planning typically focuses on data protection and application availability. Most organizations consider the information maintained on servers and storage devices to be infinitely more valuable than the technology itself. However, DR plans should also include provisions for protecting equipment from physical damage. Location: Ideally, data centers would be located in a geographic area that’s not prone to natural disaster. That’s seldom possible, so organizations must do the best they can to isolate it from any disaster that does occur. That means locating the room in an interior room or at least as far away from windows as possible. In areas where hurricanes and tornadoes are the greatest threat, an underground location may be the best option (unless flooding is a problem). In earthquake zones, it’s critical to select a well-constructed building that’s compliant with the latest codes. Backup Power: Power outages are a…

What Causes Runtime Error 6?
RecoverySoft / August 14, 2018

Runtime error 6 is an “overflow” problem that may happen for one of a handful of reasons. Runtime error 6 can occur when data gets too big for its britches. This “overflow” problem can happen when, somewhere along the way, data has been entered that is too big for its data field. What does this mean in plain English? Let’s say you’re working with Microsoft Access (a database program). You have to put information into various fields (boxes), when some of these boxes are pre-set to only accept certain values. (This can be arranged for a variety of reasons; there is no need to go into the specifics here, as it would require several articles!) If one of these fields is pre-set to accept values of only 0-255, you’d cause an overflow error if you accidentally entered, say, 377. Now of course you wouldn’t do this. However, sometimes programmers make mistakes. Sometimes a program must generate a random variable and it could be that the parameters on the generator are too wide (it generates larger numbers than it should). Nevertheless, sometimes this doesn’t happen until it’s a bit too late. That’s why searching for updates, patches, and new versions/upgrades to…

Activity Diagrams – Advantages, Disadvantages and Applications of Use
RecoverySoft / August 14, 2018

Activity diagrams describe the actual work flow behavior of a system in Information Technology. These diagrams are very similar to state Diagrams because activities are the actual state of doing something. These diagrams describe the actual state of activities of a system by showing all the sequence of activities performed. Also, these diagrams can show activities that are conditional or parallel. When to Use: Activity Diagrams Activity diagrams should be used in alignment with other modeling techniques like interaction diagrams and State diagrams. The main reason behind using these diagrams is to model the work flow behind the system being designed. these Diagrams are also useful for analyzing a use case by describing what actions need to take place and when they should occur, describing a complicated sequential algorithm and modeling applications with parallel processes. Activity diagrams’ advantages: UML modeling language included that these diagrams are normally easily comprehensible for both analysts and stakeholders. In UML for the IT Business Analyst, “The activity diagram is the one most useful to the IT BA for depicting work flow [because] it is simple to understand-both for BAs and end-users.” Since they are among the most user-friendly diagrams available, they are generally regarded…

Windows Password Reset – What to Do If You've Forgotten Your Windows Administrator Password
RecoverySoft / August 14, 2018

There are only two ways to regain access to your PC if you've forgotten your Windows Administrator password. The first is to reinstall Windows and totally wipe everything from your computer … and the second is to use a "password reset" program that will reset the password for you. Here's what to do: Method 1 – Reinstall Windows – If you've got nothing to lose from your computer, and have the knowledge to do it, you may wish to reinstall Windows to gain access to your PC again. The only problem with this method is that reinstalling Windows literally means you will lose every file and every piece of data on your PC. This is okay for some people and if you are interested in using this method, you simply need to insert the Windows disc into your PC, reboot your system and select "Boot From CD" in the BIOS options. If you do not understand how to do it, then you need to talk to a computer technician. Method 2 – Use Password Reset Software – The most common way to restore access to your PC is to "reset" the Administrator password for your system by using a piece…

iSCSI Software
RecoverySoft / August 14, 2018

iSCSI software is the type of software used in network storage where iSCSI protocol is used. The basic storage network which deploys iSCSI is storage area network (SAN). iSCSI software enables the devices to become connected to the network, share storage space and have access to the data stored on storage servers. There can be two sets of devices which are in the network. The first are iSCSI initiators – the appliances which send SCSI commands and initiate the contact. The other are iSCSI targets – the devices which receive the commands sent by the iSCSI initiator. Therefore, depending on the status of the device, it will require special iSCSI software – for initiators, for targets or both, since one device can sometimes perform both roles. In the case of iSCSI software for initiators we can have the system initiator. It is a special service running in the operation system. Windows Vista and Windows 2008 are already equipped with iSCSI software for initiator, you only have to select it. In Windows XP and Windows 2003 you can download iSCSI initiator from Microsoft pages and install it. As far as targets are concerned there are also two possibilities. Many of the…
