Now we know about adding and multiplying, and have touched on dividing (see History of the Computer - Flip-Flops a basic counter) what about subtracting and negative numbers? Once again we take the simple way.

To form a negative number, we simply invert the positive number, in binary, and add 1. For example

0000 0110 - (6) inverted becomes

1111 1001 - now add 1 to get

1111 1010 - (-6)

This is how a computer records -6. The Most Significant Bit - in this case bit 7 or bit value 128 decimal is used as the Sign Bit. If this bit is a zero, the number is positive, if it is a one, the number is negative. This notation is known as ‘Twos Complement‘.

(There is also ‘Ones Complement’, without the added 1, which was used in some proprietary systems, but it required more complicated logic to get around problems like having + and - zero. It is not necessary to go into the detail of this notation for an understanding of the logic.)

The Sign bit uses one of the bit positions, meaning that our range of numbers is reduced. For example 0111 1111 is the highest positive 8-bit number (127 decimal). The next number, 128 decimal would be 1000 0000, however the bit value 128 in bit 7 cannot be used as it is now the sign bit.

SUBTRACTION

Now we can have a negative number it will be easy to subtract. We can use an adder, which we already have. This is possible because 9-3 is the same as 9+(-3). For instance 9-3 decimal is 00001001-00000011 in 8 bit binary. We take the 9 and add it to the twos complement of 3, thus we can use our adder with a bit of extra logic to invert the negative number and add 1 to it. The twos complement of 3 (decimal) or in binary

of 0000 0011

is 1111 1100

add 1 + 0001

is 1111 1101

Now add to the 9 (decimal) using an 8 bit adder:-

7654 3210 - bit #

0000 1001 - (9)

1111 1101 - (-3)

Remember your binary addition?

Least significant bit (bit 0), 1+1 is 0 and a carry.

Next bit (bit 1) is 0+0+carry = 1 no carry.

Next bit (bit 2) is 1+0 = 1 no carry.

Next bit (bit 3) is 1+1 = 0 and a carry.

Next bit (bit 4) is 1+0+carry = 0 and a carry.

Next 3 bits (5,6,7) are the same as 4 - 1+0+carry = 0. The last carry falls off the end.*

So we get:-

0000 0110 (6 Decimal - 9-3=6)

Which, fortunately, if you followed it, is the right answer! Are these computers smart or what? This system works with negative results as well, for instance try 3-9. You should end up with the twos complement of 6. This is not a compulsory exercise!

* The carry from the most significant bit, in this example bit 7, but could be bit 31 or 63 in some computers, is ignored in this case. However it is used in some functions, for instance a circular bit shift, which we will look at in a later article.

The programs that are keeping your companies running are the ones that are crucial in the world today. Since computers have invaded our workspace they have become sophisticated and specific. As our jobs become for specific, which seems to be the trend, our software will need to be just as specific, in order to handle the demands that the market is now requiring.

So what are the things that you should be looking for in financial software? This article will focus on the financial software for payday loan lenders who are dealing with multistate functionality, adapting services and expansion.

If you are already in the business of short-term lending than you know that every state has its own laws and regulations regarding the administration and distribution of these loans. If you have sites in multiple states or are planning on being in such a situation then the type of program that you need will be even more specific.

You will need a program that tracks loans according to states and the regulations in that state, but collaborates all the information so that is accessible and easy compiled. Mistakes on state ordinances can involve costly fines and embarrassment for the company so this is not an option that should be disregarded.

Because information is always increasing and every business is constantly changing as new methods and ideas are created, your services will adapt with the market. Financial software is expensive, especially if you are looking for one that will integrate your entire company. They are not a commodity that you will want to replace often.

For this reason you will need a program that is going to be adaptable to any changes you have to make to fit the market. Look for a company that you know updates their programming and has existed for some time.

If you are shopping at the top of the market then it is likely that the software is tried and proven. You want to be sure you can count on the software you are about to purchase for a long time.

As your business grows your programming will have to as well. Some software is effective for a small business and then ineffective once the business is large.

Find a program that can deal with all you have where you are right now and where you hope your company will be in the future. Even if software is more expensive it will be worth the cost if you don’t have to replace it, pay the cost of a new program and lose effectiveness as your employees are trained to use it. Plan ahead for problems you see in the future.

Those are the most crucial things, but it is good to know that there are many options that your program could include. If you can, find software that will integrate everything that your business needs.

That could include options for both your employees and the customers. In the case of employees the program could take care of all hourly recording and tract the progress of their labors.

Make sure that the program you are considering is one that has a good track record. Find out how others have enjoyed the system and if they are satisfied with it.

Choose from well established programs and not necessarily from the newest system on the market. Software always has glitches no matter how well prepared it is to hit the market. By researching how others have enjoyed certain programs you will be able to find out if the software is functional and if all the bugs have been ironed out.

In this day and age, having the latest and greatest printer on the market is definitely something that everyone strives for. One of the biggest obstacles that people are facing, especially in this economy is the fact that printers, especially laser jet printers are very expensive. This is way the Samsung ML 1430 Printer is an extremely popular choice! This printer has everything that you want out of it without the price tag.

What a lot of people do not know about the ML 1430 model, is it is actually a replacement for the Samsung ML 1210. The newest ML 1430 is definitely the model that has all sorts of improvements on it and when you are looking for something that is fast, has better printing skills and is certainly affordable, than you are looking for the 1430 model of Samsung printers.

Looking for a printer that is good, prints in very good quality and is certainly packed with all sorts of features for under two hundred dollars can be hard. The ML 1430 model is definitely under two hundred dollars and with features like a Save Toner button, the Demo button, Cancel button and finally all sorts of other functions, you can see how mind-blowing it is that a model with all of these features can be so inexpensive!

There is about eight megabytes of memory packed into this little printer and if you are looking for a privately used printer, the ML 1430 model is perfect. The paper capacity is ideal for two or three people using it, as it can hold up to one hundred and fifty pieces of paper. However, its output does only allow for about one hundred pieces of paper to come out, so be aware of that.

One of the greatest things about this printer is the fact it is super easy to install. So many printers nowadays are very difficult to install, the ML 1430 model just has one single CD that will walk you through all of the installation processes.

Also, a great thing about this printer is you are not just limited to Windows as an operating system. It uses a bunch of different operating systems. For example, Linux, Debian, Red Hat and even Caldera Open are all operating systems that can be used in sync with these printers.

The rate that it prints out the papers is something that is extremely important to most people too.

That is extremely fast and you will notice that the printer quality is definitely crisp and totally easy to read.

In this small article we will show you the possible way of deploying Microsoft Business Solutions Great Plains for the market niche of large, mid-size and small reselling and distribution business in carpeting and floor covering, textile & fabric. We will not be talking about fabric production, but rather cutting for the end-user or small retailer. Microsoft Great Plains itself in our case should be considered as a platform for light customization and modification. WeÂ’ll describe industry requirements and the way them to be implemented in Great Plains

• Variable Length Rolls. Usually, when you place and order through your supplier – there is no way to know exact length of the roll or bolt. It might have 75 yards or 80 yards – you typically know the average length, say 77 yards and this is why you know what to expect in yards if you purchase 10 bolts

• Inventory in Yards. When you receive the roll – you need to place it into inventory in exact yards. Typical method is to assign lot number to the bolt and then associate the exact initial length in yards with this unique lot number. This is Great Plains Dexterity customization, which provides parallel unit of measure, associated with the lot number

• Light Assembly. Bill of Materials would be probably too complex for cutting the fabric. This is why we suggest to deploy automatic inventory decrease and increase adjustments – you decrease number of yards in the roll and increase your finished good in the number of units assembled

• Meter / Yard challenge. If you purchase from the supplier in China, Mexico, South East Asia or Europe – they measure their rolls in meters, not yards – so you need to implement automatic unit of measure translation and conversion. You resolve this on the level of your EDI – electronic document interchange

• Cut-beds tracking to original roll. If you are assembling/cutting something like billiard table beds – you would like them to be tracked to the original roll in the case of customer complaint. This means that you will have to assign the same or modified lot number to the cut-bed

• Inventory Count. You need to track what is the current length of the bolt/roll. This is realized via custom Dexterity table, having Item Number, Lot Number, Initial Length in Yards, Current Length in Yards

• Customization Tools: Great Plains Dexterity – this is Great Plains Dynamics programming language and development environment; Modifier with VBA – will allow your modify Great Plains forms and attach VBA scripts to your custom buttons; SQL scripts and stored procedures – low level database programming, excellent for the professional with profound GP tables structure and data flow knowledge.

Up until a few years ago, making music meant a massive investment in time and money. Those days are fortunately gone now, you can use your computer to record and edit your vocals or instruments, and burn a CD of your work afterwards, ready to be played on your CD player.

In order to make music with your computer, the minimum you need is a soundcard and good software. Modern computers usually ship with a built-in soundcard already, which is sufficient to start with - just connect an amplifier or headphones to it. Nearly all soundcards have Mic In/Line in connectors as well, so if you wish to record vocals or instruments, you only need to purchase a microphone and connect that. Although some soundcards come bundled with a microphone already, those are usually of poor quality and not suitable for decent music production. Thus a good idea here is to seek advice in your local music store.

Next you need to find good music software. Fortunately there is a lot of applications available for all common computer platforms, no matter if you are using Windows, Linux or Mac OS X. To find good applications for your platform, type something like “Music Software for PC” into your favourite search engine.

A good idea is to start with free software, then move on to commercial software once you got the hang of it and your requirements grow. You might also want to look at the applications that are given away for free on cover CDs of music magazines, or those that come bundled with your soundcard. Some music software developers give away older, discontinued or feature-limited versions of their software for free. Often such software is more capable than software which has always been distributed for free.

What is adware?

There are two types of adware, good and bad. The good is normally included in a software package that is usually distributed for free and the displayed ads are used to pay the author for the software. The good will only install if the user so chooses to install it, and can be easily uninstalled by the user using the add / remove programs function or uninstall program. The bad is actually spyware that collects data about the user and user’s surfing habits to show intrusive advertisements in your web browser. The bad will install itself without user permission and is usually very difficult to get rid of. Bad adware will hijack your web browser and internet connection. This article will address the removal of the bad.

Generally, adware is any software application that displays advertisements. These advertisements can be in the form of banner advertisements, or pop-up windows. It gathers information about the user and passes it on to third party advertisers, usually unknown to the user. A lot of times these programs are collecting data in the background, running programs that are unseen by the user. This is information theft.

What is spyware?

Spyware and adware work hand in hand. The spyware gathers the information to send to to the advertisers that are willing to pay for this information. This information is usually used to tell the advertiser what goods and services you are likely to be interested in. Ever been to a particular web site about a certain subject then suddenly you start seeing junk e-mail coming in about this product? You might not have even given out any information to this web site. You have been infected with spyware and adware.

Spyware / adware prevention methods:

Installing a different OS (operating system) other than Windows is a good way to stop the adware. This is not always the most feasible method, probably the best if you can. Most spyware / adware is written to exploit the security flaws in the Windows OS’s. Try to avoid the tool bar applications for your browser. Some are tempting and seem useful, but the bottom line is most of them are sending data about you somewhere else. Keep up with the security patches and updates for your installed software. Try to use an alternative web browser other than Internet Explorer. Install some sort of ad-blocking software. While this may not protect from the adware being installed, it is a good way to prevent the ads from annoying you.

How to remove spyware / adware.

The only way to safely remove these is by the use of a software application that is coded specifically for spyware / adware removal. Most programs that will remove spyware, will also remove adware.

Imagine a time when you never have to buy another piece of software or hardware again. You would never have to worry about hiring more support to accommodate your companies’ growth initiatives and technological investments. Your company could have the most updated software available all the time. Weather your a small business or a large business, you could take advantage of gaining access to the best technology in the market. This imagination can become a reality and this reality is closer than you think.

Software as a Service (SaaS) allows immediate access to a host of software products by renting the use of a companies software, hardware and other technological product offerings that can enhance the day to day performance of your business, office or corporation. SaaS companies offer this at a fraction of the cost as compared to purchasing this outright.

Let’s say your boss gives you a business directive to exponentially expand the amount of projects that you are implementing for your clients but your fiscally forested budget for the next budget cycle did not build in the costs to acquire new project management tools. You have been told by your boss that there is limited amounts of variance that can be built into the budget to accommodate a well thought out task for resources that you may require to keep this new initiative alive. You know from a prior request for new project resources that the cost to flat out buy everything your department needs goes way beyond the budgetary expectations established. It may be worth your time to investigate the options a SaaS company can offer. Your business would gain immediate access to Microsoft Project Management Software allowing your team to take advantage of this production management tool sooner rather than later.

Your team is elated with their ability to utilize Microsoft Project Web Access or MS Project Web Access to manage their work loads using the new cutting edge tools associated with the new software as a service package. Your boss decides to offer you that promotion that you have been chasing for the past 2 years. That can be considered a win in any arena.
