Civilization 4 and Why I Hate My Office Phone

If you’re familiar with the strategy PC gaming series “Civilization”, you probably know that it’s only slightly less addictive than crack. I’ve never tried crack, but the “word on the street”, so to speak, is that it’s a bit hard to let go of. I recently purchased Civilization 4, which is the latest in the Civilization series. That in itself isn’t so interesting, but what happened to me at my job as a result of it most certainly is. I work as a network administrator for a large insurance company in Illinois.

Part of my job is to repair PC’s as needed, which is quite often considering how many there are around this place. I informed my coworker, also a big civilization fan that I had the game and he suggested I bring it in for a little test run. Against my better judgment, we decided to play a hot seat game during work. “Hot seat” means that one player takes a turn, followed by the other, which is only possible with turn based games such as Civ. We both figured that there would always be one of us to answer the phone in our little repair-shop cubbyhole so we didn’t see how we could possibly get caught. Boy were we wrong! About four hours into a game things started getting interesting.

My civilization found his civilization and we started going to war against each other, as one might expect. I sat down for my turn and my coworker decided to head off to the bathroom. The phone rang, and I didn’t pick up so that whoever was on the other end wouldn’t hear the Civ theme music or the explosive sound of my Panzers running over his infantry. What I failed to remember is that our advanced phone system allows anyone to communicate with us on an open speaker phone provided we aren’t on the phone already. My boss utilized this function since no one answered while I was taking my turn…o.k., actually while I was taking my turn and bragging out loud to myself about how well I was doing in the game. I found myself in his office that afternoon, but luckily I was only reprimanded and not fired. Not only did I get into trouble, my coworker continues to make jokes about it at my expense.

I hate my office phone.

A Proposed Hardware Reference Model for Spatial Transformation and Quantization in H.264,

 

This paper presents three Very Large Scale Integration prototypes to exploit spatial redundancy in the H.264 standard. The proposed architectures are: (1) forward 4 × 4 integer approximation of DCT transform and quantization, which is applied to all blocks of a frame, (2) the 4 × 4 Hadamard transform and quantization that is applied to the DC coefficients of the luma component when the macroblock is encoded in 16 × 16 intra prediction mode, and (3) the 2 × 2 Hadamard transform and quantization that is applied to the DC coefficients of the chroma component as a second level in the transformation hierarchy. The developed algorithms are adopted by the H.264 standard. A performance analysis shows that the architectures satisfy the real-time constraints required by different digital video applications.

Clutter out, Color in: Make Your Office Work for You

Is your workspace working for you? Research shows that your environment makes an impact on your mood. So it may be time to give your space at the office a makeover to liven up things at work.

“Now you can change your office decor as often as you change the ink in your printer,” says Anna Griffin, designer of the Anna Griffin Inc. line of desk accessories. “A change of color and pattern in your workspace can help to motivate, destress and even improve your disposition.”

The key is to add variety to your area so that you don’t get bored with the same surroundings and decor day after day. Griffin offers the following tips to help you create a pleasing and invigorating work area.

* Clear the clutter. The first step in producing a pleasant cubicle space is to make it clean and organized. This will help you stay focused on your work.

* Accessorize. Disposable desk accessories in fun colors and patterns will add instant pizzazz to your workspace and can be replaced whenever you need a change of ambience.

The “Rose” and “Elsie” collections from Anna Griffin Inc. are fresh, fun and, best of all, affordable. They feature four different patterns in eight coordinating office items, including file sets, magazine and pencil holders, paper, letter bins, journals and photo albums. The Rose Collection is full of rich, vibrant color in Old World floral patterns, while the Elsie Collection is sophisticated and playful, incorporating retro, pastel abstract and floral designs.

* Decorate your workspace to look like home. Because you spend so much time at work, choose a color or style and start decorating. A small area rug can add color and texture to your space, and a favorite lamp or lamp shade can cast just the right light. You can personalize with touches like a decorative basket as an “in box” and fun prints and paintings for the walls. Don’t forget photos of your family, friends and pets. They will bring a smile and help reduce your stress level.

* Just add water. A desktop fountain, fresh flowers or a fishbowl can add ambience and a sense of style and tranquility to your office space.

* Don’t forget the finishing touches. Use a pre-made slipcover to add style and color to that tired old desk chair. Switch out those boring manila folders with decorative patterned ones. They make work fun! Show some individuality with your mouse pad. You can purchase a mouse pad featuring an art masterpiece or cartoon character, depending on your theme and mood. A whimsical clock, fun paperweight or funky plant could be just what you need to make the space more “you.”

Choosing a Company Name

When forming a limited company the name of the company can be an important decision. Some people may choose the first name that they think of and others may select a ready made company for speed or because they like a particular name. However, many businesses may prefer to select a company name that either clearly distinguishes itself from its competitors or contains something unique or personal. Company names can be chosen for different reasons.

One of the most common ways of selecting a company name is to use something personal. A quick look through your local newspaper will probably introduce you to many personalised business names. Johnson Consulting Limited, T Smith & Son Limited, Stephens & Barley Limited are some fictional examples of what may be found. This may instantly make a company recognisable locally, it can be deemed as more personal by its customers, and often works well within geographical areas. However, it does little to tell new customers what your company does.

A popular choice for a small business is to choose a name that is ëdescriptiveí. This tells prospective clients exactly what your company does. Examples of this may be to call your business The Window Company Limited, City IT Consultants Limited or The Advertising Agency Limited. Whilst this does serve to reinforce your primary business it offers little differentiation and may easily be adapted by competitors.

A less personal option is to use a company name that is ëassociativeí. This type of company name helps to create an image or connection to your business activity. It is less direct than using a descriptive name but helps to position your companyís name within the market through peoples understanding of what words mean. For example a flick through the Yellow Pages will offer plenty of examples of this. A hairdresser called Classic Cuts or a printer called Selectaprint Limited are examples of what may be found. These names offer some differentiation but may not ultimately set your company aside from its competitors.

An alternative is to choose a company name that is ëfreestandingí. These names are completely abstract and not related to the companies business activities. A fictional example may be to call your catering company Zedoc Limited. There are many popular brand names that illustrate this point. Consider, Kodak, Gillette, or Mars, these names will probably be instantly recognisable to you and conjure up a particular product or business. This is a good way of setting your company aside from the competition but it is important to consider the market that you operate in. Will your prospective clients know what your business is offering?

Choosing a company name may be a simple process, but it is not uncommon for people to deliberate over names for quite some time. Whilst company names can, and often are, changed during the life of the company most people like to choose a name that they like from the outset. Therefore consider your market, how much you want to differentiate from your competitors and what your company name should say about your organisation. Once the decision is made focus on the important business of making your company a success.

Business Merchant Accounts, Business-Merchant-Accounts

Business merchant accounts are critical to have if you want to accept credit cards. Business merchant accounts are not limited to those computer consultants reselling products either. They are a good idea for any sale, especially when you are selling to new clients.

If you have a business merchant account you will not have to chase down outstanding debt. The cost is not that high and you don’t have to buy traditional credit card processing equipment. Now they have what is called a lab terminal, which allows you to use your web browser to manage the transactions. The systems are completely secure and most business merchant account providers team up with larger companies that offer great advantages.

Costco’s Business Merchant Account
One of the biggest secrets we learned about business merchant accounts is that Costco provides a fantastic deal on credit card processing through Nova Systems. It’s such a great deal it can actually pay for your entire Costco membership. Here are some particulars:
All of the monthly statement and gateway fees are waived – savings of $25 – $50 per month
Very competitive discount rates on Visa and MasterCard.
You can add on processing for American Express and Discover – you will find that even though American Express transaction fees are higher, it is a very popular card with small businesses.
The charges billed are transferred quickly and directly into your business bank account – this is a lot faster than doing your billing or invoicing once a week or so.

Paypal

Paypal is a popular alternative to traditional business merchant accounts. Paypal is very easy to set up and the set up is free. There are restrictions though on what you can do and how you can withdraw your money. The largest drawback is the negative connotation of being an ebay related service where people sell garage sale stuff as a hobby.

The Bottom Line on Business Merchant Accounts

Business merchant accounts will help you get paid faster. There are fees involved but the customer convenience and no hassle approach to receiving your money make it worthwhile. There are different business merchant accounts available so do your homework and choose the one that makes the best sense for you.

Cheaper is Not Always Better

I work for a large insurance firm in the northwest, in an office with over 500 other employees. Management recently decided to replace our existing phone system as the old system was no longer meeting our needs. I and my co-workers were under the impression that they were going to update the system, as in “make an improvement”, and that we would have late model phones with technological advancements galore. Boy, were we in for a surprise.

One day a few weeks ago, we all came in to find new phones on our desks. These were not the state-of-the-art communication devices we had in mind. Instead of the sleek, sophisticated, caller IDing, multi-line handling, LCD displaying wonders of the modern age we all dreamed of, there was a simple phone with a keypad on the receiver…not unlike what you might have had at home 15 years ago. In addition to the new phone, there was a sheet which explained in graphically painful detail exactly which series of buttons one would have to push in order to make this thing function properly. We had to now enter a digit to put someone on hold, enter a three digit code to transfer someone (one digit, dial tone, two digits) and enter a ridiculously long series of numbers to access our voicemail.

Needless to say, we were in shock. I knew it wouldn’t take long before the roars of complaining would drown out the usual office din. Sure enough, by lunchtime our office manager came in to tell everyone that we were simply going to “try it out for a while” and that the company had saved thousands by choosing this option. I and the other employees were fairly certain that we had already lost thousands in reduced productivity that morning alone. Oh, well…it’s their company, we just bring in the money for them.

For the next few days, we tried to get used to saying “hold, please, while I transfer you”, removing the receiver from our faces and trying not to curse as we made a lame-duck attempt at pressing keys, listening and pressing more keys. It was a nightmare. We were getting pretty fed up with it, but just assumed that this was what we would have to deal with. Then, out of the blue, we came in one day to find real phones with real features at our desks. No more looking at the receiver while we frantically tried to key in numbers fast enough not to drop the call. No more ten digit voicemail “pins”. No more of having no idea who was calling or where the call came from. Ahhhh, relief at last.

Later the same day, we heard a rumor circulating around the office that the VP of operations had returned from a two week trip to New York. His words, upon seeing one of the phones management had originally purchased on his desk were, “get rid of them”. All it took were those four words from a higher-up to set things right. Unbelievable.

A Computational Memory Architecture for MPEG-4 Applications with Mobile Devices

 

This paper presents a Computational Memory architecture for MPEG-4 applications with mobile devices. The proposed architecture is used for real-time block-based motion estimation, which is the most computational intensive task in the video encoder. It uses the exhaustive block-matching algorithm (EBMA) for motion estimation. The proposed architecture consists of embedded SRAMs and a number of block-matching units working in parallel to process video data while stored in the memory. The block-matching units access the embedded SRAMs simultaneously, which increases the speed of the architecture.

The architecture processes CIF format video sequences (i.e., the frame size is 352 × 288 pixels) with block size of 16 × 16 pixels and ±15 pixels search range. The proposed architecture has been designed, prototyped, and simulated for 0.18 μm TSMC CMOS technology. The simulation shows that the proposed architectures processes up to 126 CIF frames per second with clock frequency 100 MHz. The synthesized prototype of the proposed architecture includes 200 KB memory and it has an area of 33.75 mm2 and consumes 986.96 mW @100 MHz.

Business Basics for Catalog Retailers

Catalog retail is a world all it’s own. Many considerations that other retailers don’t have to deal with are of utmost importance to a catalog retailer. To name a few, the ordering process, warehousing and shipping must be streamlined for maximum efficiency. Maintaining a top notch inventory control and receiving department is also very crucial to business success. Above all, however, a catalog retailer must have a quality business phone system.

Considering the fact that the majority of customers will reach you over the phone, it is paramount to be able to not only handle call volume during peak times, but also to provide your customers service representatives with the features they need to do their job well. Business phone systems should be capable of not only putting your customers in touch with you, but also offer routing flexibility, voicemail and forwarding options for the administrative side of your company. Often, the difference maker for catalog retailers is not the products they sell, but the service behind those products. People who want to buy will have questions regarding an item that a simple picture and brief description will not answer. Most companies have service reps who take orders and product specialists who are familiar with the inventory.

It is essential for the product specialists to have access to a phone system that will accurately and easily allow them to receive and transfer calls between departments. After the initial contact by the sales representatives, the most common transfer of waiting customers will be to product specialists and hopefully back to the sales reps. A customer who is dropped accidentally during this transfer is likely to not call back. Additionally, customers who are made to hold for extended periods of time without an automated message thanking them for their patience are a primary example of lost revenue that could be curtailed by the proper business phone system. All in all, a well thought out business phone system is an integral necessity for any company, but it is especially important for catalog retailers.

An Affine Based Algorithm and SIMD Architecture for Video Compression with Low Bit-rate Applications

This paper presents a new affine-based algorithm and SIMD architecture for video compression with low bit rate applications. The proposed algorithm is used for mesh-based motion estimation and it is named mesh-based square-matching algorithm (MB-SMA). The MB-SMA is a simplified version of the hexagonal matching algorithm [1]. In this algorithm, right-angled triangular mesh is used to benefit from a multiplication free algorithm presented in [2] for computing the affine parameters. The proposed algorithm has lower computational cost than the hexagonal matching algorithm while it produces almost the same peak signal-to-noise ratio (PSNR) values. The MB-SMA outperforms the commonly used motion estimation algorithms in terms of computational cost, efficiency and video quality (i.e., PSNR). The MB-SMA is implemented using an SIMD architecture in which a large number of processing elements has been embedded with SRAM blocks to utilize the large internal memory bandwidth. The proposed architecture needs 26.9 ms to process one CIF video frame. Therefore, it can process 37 CIF frames/s. The proposed architecture has been prototyped using Taiwan Semiconductor Manufacturing Company (TSMC) 0.18-μm CMOS technology and the embedded SRAMs have been generated using Virage Logic memory compiler.
