1) NOT KISSING FIRST. Avoiding her lips and diving straight for the erogenous zones makes her feel like you're paying bythe hour and trying to get your money's worth by cutting out nonessentials. A proper passionate kiss is the ultimate form of foreplay.

2) BLOWING TOO HARD IN HER EAR. Admit it, some kid at school told you girls love this. Well, there's a difference between being erotic and blowing as if you're trying to extinguish the candles on your 50th birthday cake. That hurts.

3) NOT SHAVING. You often forget you have a porcupine strapped to your chin which you rake repeatedly across your partner's face and thighs. When she turns her head from side to side, it's not passion, it's avoidance.

4) SQUEEZING HER BREAST. Most men act like a housewife testing a melon for ripeness when they get their hand on a pair. Stroke, caress, and smooth them.

5) BITING HER NIPPLES. Why do men fasten onto a woman's nipples, then clamp down like they're trying to deflate her body via her breasts? Nipples are highly sensitive. They can't stand up to chewing. Lick and suck them gently. Flicking your tongue across them is good. Pretending they're a dogie toy isn't.

6) TWIDDLING HER NIPPLES. Stop doing that thing where you twiddle the nipples between finger and thumb like you're trying to find a radio station in a hilly area. Focus on the whole breasts, not just the exclamation points.

7) IGNORING THE OTHER PARTS OF HER BODY. A woman is not a highway with just three turnoffs: Breastville East and West, and the Midtown Tunnel. There are vast areas of her body which you've ignored far too often as you go bombing straight into downtown Vagina. So start paying them some attention.

8) GETTING THE HAND TRAPPED. Poor manual dexterity in the underskirt region can result in tangled fingers and underpants. If you're going to be that aggressive, just ask her to take the damn things off.

9) LEAVING HER A LITTLE PRESENT. Condom disposal is the man's responsibility. You wore it, you store it.

10) ATTACKING THE CLITORIS. Direct pressure is very unpleasant, so gently rotate your fingers along side of the clitoris.

11) STOPPING FOR A BREAK. Women, unlike men, don't pick up where they left off. If you stop, they plummet back to square one very fast. If you can tell she's not there,keep going at all costs, numb jaw or not.

12) UNDRESSING HER AWKWARDLY. Women hate looking stupid, but stupid she will look when naked at the waist with a sweater stuck over her head. Unwrap her like an elegant present, not a kid's toy.

13) GIVING HER A WEDGIE DURING FOREPLAY. Stroking her gently through her panties can be very sexy. Pulling the material up between her thighs and yanking it back and forth is not.

14) BEING OBSESSED WITH THE VAGINA. Although most men can find the clitoris without maps, they still believe that the vagina is where it's all at. No sooner is your hand down there than you're trying to stuff stolen banknotes up a chimney. This is okay in principle, but if you're not careful, it can hurt so don't get carried away. It's best to pay more attention to her clitoris and the exterior of her vagina at first, then gently slip a finger inside her and see if she likes it.

15) MASSAGING TOO ROUGHLY. You're attempting to give her a sensual, relaxing massage to get her in the mood. Hands and fingertips are okay; elbows and knees are not.

16) UNDRESSING PREMATURELY. Don't force the issue by stripping before she's at least made some move toward getting your stuff off, even if it's just undoing a couple of buttons.

17) TAKING YOUR PANTS OFF FIRST. A man in socks and underpants is a at his worst. Lose the socks first.

18) GOING TOO FAST. When you get to the penis-in-vagina situation, the worst thing you can do is pump away like an industrial power tool she'll soon feel like an assembly-line worker made obsolete by your technology. Build up slowly,with clean, straight, regular thrusts.

19) GOING TOO HARD. If you bash your great triangular hip bones into her thigh or stomach, the pain is equal to two weeks of horseback riding concentrated into a few seconds.

20) COMING TOO SOON. Every man's fear. With reason. If you shoot before you see the whites of her eyes, make sure you have a backup plan to ensure her pleasure too.

21) NOT COMING SOON ENOUGH. > It may appear to you that humping for an hour without climaxing is the > mark of a sex god, but to her it's more likely the mark of a numb vagina. > At least buy some intriguing wall hangings, so she has something > to hold her interest while you're playing Marathon Man. > >

22) ASKING IF SHE HAS COME. > You really ought to be able to tell. Most women make noise. But if you > really don't know, don't ask > >

23) PERFORMING ORAL SEX TOO GENTLY. > Don't act like a giant cat at a saucer of milk. Get your whole mouth > down there, and concentrate on gently rotating or flicking your tongue on > her clitoris. > >

24) NUDGING HER HEAD DOWN. > Men persist in doing this until she's eyeball-to-penis, hoping that it > will lead very swiftly to mouth-to-penis. All women hate this.It's about > three steps from being dragged to a cave by their hair. If you want her to > use her mouth, use yours; try talking seductively to her. > >

25) NOT WARNING HER BEFORE YOU CLIMAX. > Sperm tastes like sea water mixed with egg white. Not everybody likes > it.When she's performing oral sex, warn her before you come so she can do > what's necessary. > >

26) MOVING AROUND DURING FELLATIO. > Don't thrust. She'll do all the moving during fellatio. You just lie > there. And don't grab her head. > >

27) TAKING ETIQUETTE ADVICE FROM PORN MOVIES. > In X-rated movies, women seem to love it when men ejaculate over them. In > real life, it just means more laundry to do. > >

28) MAKING HER RIDE ON TOP FOR AGES. > Asking her to be on top is fine. Lying there grunting while she does > all the hard work is not. Caress her gently, so that she doesn't feel quite > so much like the captain of a schooner. And let her have a rest. > >

29) ATTEMPTING ANAL SEX AND PRETENDING IT WAS > AN ACCIDENT. > This is how men earn a reputation for not being able to follow > directions.If you want to put it there, ask her first. And don't think > that being drunk is an excuse. > >

30) TAKING PICTURES. > When a man says, "Can I take a photo of you?" she'll hear the words > to show my buddies." At least let her have custody of them. > >

31) NOT BEING IMAGINATIVE ENOUGH. > Imagination is anything from drawing patterns on her back to pouring > honey on her and licking it off. Fruit, vegetables, ice and feathers are > all handy props; hot candle wax and permanent dye are a no no. > >

32) SLAPPING YOUR STOMACH AGAINST HERS. > There is no less erotic noise. It's as sexy as a belching contest. > >

33) ARRANGING HER IN STUPID POSES. > If she wants to do advanced yoga in bed, fine, but unless she's a > Romanian gymnast, don't get too ambitious. Ask yourself if you want a > sexual partner with snapped hamstrings. > >

34) LOOKING FOR HER PROSTATE. > Read this carefully: Anal stimulation feels good for men because they > have a prostate. Women don't. > >

35) GIVING LOVE BITES. > It is highly erotic to exert some gentle suction on the sides of the > neck, if you do it carefully. No woman wants to have to wear turtlenecks > and jaunty scarves for weeks on end. > >

36) BARKING INSTRUCTIONS. > Don't shout encouragement like a coach with a megaphone. It's not a > big turn-on. > >

37) TALKING DIRTY. > It makes you sound like a lonely magazine editor calling a 1-900 line. > If she likes nasty talk, she'll let you know > >

38) NOT CARING WHETHER SHE COMES. > You have to finish the job. Keep on trying until you get it right, and > she might even do the same for you. > >

39) SQUASHING HER. > Men generally weigh more than women, so if you lie on her a bit too > heavily, she will turn blue. > >

40) THANKING HER. > Never thank a woman for having sex with you.Your bedroom is not a soup > kitchen. > > Send this to everyone you know or else you'll have bad sex for ever!

What is a PLC ?


Programmable Logic Controller is a solid-state control system that has a user-programmable memory for storage of instructions to implement specific functions such as Input/output (I/O) control, logic, timing , counting, report generation, communication, arithmetic, and data file manipulation. A controller consists of a central processor, inputoutput interface, and memory. A controller is designed as an industrial control system.

Simply put, a PLC is a computer like control device that reads input and energizes electrical devices called outputs based on a user programmable memory. This controls machinery or an industrial process.

Programmable Logic Controllers or PLC are the hub of many manufacturing processes. These microprocessor based units are used in processes as simple as boxing machines or bagging equipment to controlling and tracking sophisticated manufacturing processes. They are in virtually all new manufacturing, processing and packing equipment in one form or another. Because of their popularity in industry, it becomes increasingly more important to learn skills related to these devices.

How does a PLC work ?


The microprocessor or processor module is the brain of a PLC system. It consists of the microprocessor, memory integrated circuits, and circuits necessary to store and retrieve information from memory. It also includes communications ports to other peripherals, other PLC’s or programming terminals. Today’s processors vary widely in their capabilities to control real world devices. Some control as few as 6 inputs and outputs (I/O) and others 40,000 or more. One processor can control more than one process or manufacturing line. Processors are often linked together in order to provided continuity throughout the process. The number of inputs and outputs PLCs can control are limited by the overall capacity of the PLC system hardware and memory capabilities. The job of the processor is to monitor status or state of input devices, scan and solve the logic of a user program, and ntrol on or off state of output devices.

Types of Processor Memory

RAM or Random Access Memory is a volatile memory that would lose it’s information if power were removed.. This is why some processor units incorporate a battery back up. The type of RAM normally used is CMOS or Complementary Metal Oxide Semiconductor. CMOS RAM is used for storage of the user’s program (ladder logic diagrams) and storage memory.

ROM or Read Only Memory is a nonvolatile type of memory. This means you don’t need an external power source to keep information. In this type of memory, information can be read, but not changed. For this reason the manufacture sometimes calls this firmware. It is placed there for the internal use and operation of processor units.
EEPROM or Electrically Erasable

Programmable Read Only Memory is usually an add-on memory module that is used to back up the main program in CMOS RAM of the processor. In many cases, the processor can be programmed to load the EEPOM’s program to RAM if RAM is lost or corrupted.

Input Module

There are many types of input modules to choose from. The type of input module used is dependent upon what real world input to the PLC is desired. Some examples of inputs are limit switches, electric eyes, and pushbuttons. DC inputs, such as thumbwheel switches, can be used to enter integer values to be manipulated by the PLC. DC input cards areused for this application. Since most industrial power systems are inherently noisy, electrical isolation is provided between the input and the processor. Electromagnetic interference (EMI) and Radio Frequency Interference (RFI) can cause severe problems in most solid state control systems. The component used most often to provide electrical isolation within I/O cards is called an optical isolator or optocoupler. The wiring of an input is not complex. The object is to get a voltage at a particular point on the card. Typically there are 8 to 32 input points on any one input module. Each point will be assigned a unique address by the processor. Analog input modules are special input cards that use analog to digital conversion (A to D) to sense variables such as temperature, speed, pressure, and position. The external device normally is connected to a controller (transducer) producing an electrical signal the analog input card can interpret. This signal is usually 4ma to 20 ma or a 0 to 10 volt signal.

Output Module

Output modules can be for used for ac or dc devices such as solenoids, relays, contractors, pilot lamps, and LED readouts. Output cards usually have from 6 to 32 output points on a single module. The output device within the card provides the connection from the user power supply to the load. Usually silicon controlled rectifiers (SCR), triac, or dry contact relays are use for this purpose. Individual outputs are rated most often at 2 to 3 amperes. Output cards, like input cards have electrical isolation between the load being connected and the PLC. Analog output cards are a special type of output modules that use digital to analog conversion (D to A). The analog output module can take a value stored in a 12 bit file and convert it to an analog signal. Normally this signal is 0 -10 volts dc or 4ma to 20 ma. This analog signal is often used in equipment such as motor operated valves and pneumatic position control devices.

System Power Supply

The PLC power supply is highly specialized to provide the necessary voltage levels for the PLC’s internal operation. Typically this power supply must provide current to operate the input and output modules as well as the processor. The typical output of this power supply is 5 VDC.

Programming Terminal

The most common types of programming device used today are hand held programmers, desktop IBM compatible computers, and laptop IBM compatible machines. Programming terminals are used to develop and enter the user program into memory of the PLC. The program language of choice, is ladder logic. Ladder logic is made up of a set of specialized instructions used in different combinations to control the operation sequence of the driven machinery or process. Programmers, when used offline, are simply used to construct the program. The program can be downloaded to the processor latter. When the programmer is used online, it can be used to monitor the program. This can be an extremely effective troubleshooting tool when used correctly.

Long Hair Is Sexy?

Long hair is for men what short hair is to women, a choice of lifestyle. lilithgallery

“There is no legal limit for a man or woman to growing out their hair, but what is important, is that a man be cautious when he grow out his hair that he not intend to imitate women, nor the people of sin and shamelessness. If he intends this, it is haram.”

Singapore IC Checker

The Singapore NRIC number is made up of 7 digits and a letter behind. This letter is calculated from the first 7 digits using the modulus eleven method, similar to the method used for calculating the check digit of the ISBN Code.

The steps involved to obtain the check digit is

Multiply each digit in the NRIC number by its weight.
Add together the above products.
Divide the resulting sum by 11.
Subtract the remainder from 11 to give the check digit.
Check the check digit against the table to obtain the alphabet.
The following table shows the weight for the NRIC number in Singapore :

2 7 6 5 4 3 2

The following table is used to change the check digit into the corresponding alphabet.

Check Digit
1 2 3 4 5 6 7 8 9 10 11


This system is used to prevent illegal workers from entering Singapore with a fake passport using a fake NRIC number.

A person has a NRIC number S1234567A

To find out if the NRIC number is valid, we need to use the method above.

2(weight)*1(NRIC number) + 7(weight)*2(NRIC number) + 6(weight)*3 + 5*4 + 4*5 + 3*6 + 2*7 = 106

106/11 = 9 r 7

11-7 = 4

Using the table above, if the check digit is 4, then the alphabet at the end of the NRIC number should be D. So, we can conclude that this NRIC number is invalid.

Best Possible Video Connection

Found this infomation from website.

There are three types of video connections that offer different levels of video quality:

Component Video (Best Quality)

Component video provides the best color separation, using the full bandwidth of black and white to produce the sharpest image. Red, green and blue signals are divided between the Pb and Pr cables, and the black and white signal is passed through the Y cable. The jacks on your TV set may be color-coded as (Pb) blue, (Pr) red, and (Y) green. Alternately, the TV jacks may be labeled Cb, Cr and Y.

S-Video (Better Quality)

S-Video is short for Super-Video. It is an available connection on most DVD players. S-Video is a high-quality method of transmitting video signals over cable to a television. S-Video separates information into two signals: Chrominance (color) and Luminance (brightness). This prevents color bleeding and the moving line of dots between colors, a phenomenon described as ‘Dot Crawl’, and increases clarity and sharpness. Once the information is finally delivered to the TV, it is done so as a single signal over one wire.

Composite Video (Good Quality)

The yellow composite video connector is typically part of a three-cable bundle that includes the red and white audio connectors. Older TV sets may only have this video connection available.

A composite video input combines the black and white component (Y) and the color difference component (C) into one signal. With these components combined into a composite signal, they cannot be separated once the TV set receives the signal. Thus, color separation is not sharply defined, and the edges of color images may exhibit ‘Dot Crawl’.


Scan the entire test first.

Do those problems which appear easy first. Go back to the harder ones later. Problems which at first appear difficult may seem easier on the second reading.

Never leave a multiple-choice question blank unless you will be penalized for wrong answers. Try to use process of elimination to narrow down your choices.

Do not be intimidated by classmates who leave the test session early.

Check your work if you have time. The easier problems especially should be checked for computational errors, miscopied numbers, or any type of mechanical mistake.

Learn from your mistakes! Do not throw out returned exams, but correct every error, then keep the test to prepare for the Final Exam.


Take notes in outline form, not in paragraph form. Use some type of notebook to keep notes together and in order.

Write problems along with the solutions.

Do not copy every example done in class. Sit back and focus on the process.

Record page numbers and problem numbers of examples done from the textbook to help you coordinate your notes with the textbook.

Leave space for future comments or corrections. If is useful to write only on the left side of the notebook page, and leave the right side for future comments, correction or explanations.

Rewrite your notes to help you review and organize the information.

Use an index card to record formulas and procedures that should be memorized. Review these often.

Review your notes often.

0.00: What is the purpose of this FAQ?
A: To educate and inform. This FAQ deals with standard analog telephonewiring only. It does not pretend to deal with any other telephone system,such as ISDN. Entertainment included at no extra charge to you (unlessyou’re on CompuSteal, America OnLose, or Progeny and are paying mucho-bucksper hour and I am wasting your time).

0.01: What is a telephone?
A: A telephone is a device which allows people to communicate by voiceover great distances at relatively inexpensive cost (compared to a planeticket). If Alexander Graham Bell had invented it today, it would be calleda “Vocal communications network access terminal (VC-NAT).”

0.02: What is pulse/tone?
A: “Pulse” and “tone” are two very different dialing protocols. Mosttelephone networks are capable of handling either protocol; use tone ifpossible. For a more detailed explanation, see section 4.01, “How doesa telephone dial?”


SECTION 1: Equipment
1.01: What jack types are available?
A: There are several types, the most common being the “modular” style.Also is hard-wire, and four-prong.

1.02: What is meant by RJ11/RJ14/RJ45 in jack types?
A: These are types of modular jacks. RJ11 is a small, 4-position modularjack (like on the handset). RJ14 is a 6-position jack (usu. with 2 or 4wires) such as the line cord. RJ45 is an 8-position jack, not often usedfor standard telephones, but is used for some “system” telephones and forEthernet (computer) wiring.

SECTION 2: Wires and color codes
2.01: What is the proper type of wire to use?
A: Telephone wire must have the letters “CM” in its type rating. Telephonewire size is referred to in “pairs”– such as 2-pair (4-wire), 3-pair (6-wire),and so on. Wire smaller than 24 AWG should never be used.
Although it is available, 1- and 2-pair wire is not recommended, asit is usually not twisted, and should it fail, there are no extra pairsto fall back on.
6- or 8- pair is recommended. The wire should be CAT-2 or better. I highly recommend using CAT-5, as the price difference is minimal if youshop around for it.

2.02: What does twisting have to do with anything?
A: Twisting each _pair_ (not the whole cable) helps reduce signal lossand rejects interference. Also helps prevent “crosstalk” (where a signalbleeds from one pair to another). The tighter the twist, the clearer theline.
CAT-1 is not twisted at all, and CAT-2 is barely so. I recommend goingwith at least CAT-3 4-pair wire, especially if you plan to use a modem.
If you’re really fanatical, you could do your telephone wiring withbalanced microphone cable (2 conductors plus shield). Just be sure youground the shield at the phone co. interface box ONLY (don’t connect itto the line wires).

2.03: What are the color codes for lines 1/2/3/4/etc.?
A: Note that a standard RJ14 jack has six positions and may have two,four, or six pins. There are two color codes, described below:

Pair: Ring (-): Tip (+)
1 Red Green
2 Yellow Black
3 Blue White
1 Blue/WH White/BU
2 Orange/WH White/OR
3 Green/WH White/GN
4 Brown/WH White/BN

There are additional colors for cables with more than 4 pairs, but Idon’t know what they are right now. When I find out I’ll include the listin an appendix.

As you look at the _jack_ from the “front”, with the tab slot down,the pins are arranged as so:
4R-3T-2T-1R-1T-2R-3R-4T (eight pos.-eightpins RJ45)
3T-2T-1R-1T-2R-3R (six positions-six pins RJ14)
xx-2T-1R-1T-2R-xx (six positions-four pins RJ14)

The “white” may or may not have a color band corresponding to its partnercolor.

2.04: What special considerations should I have for modem use?
A: See also question 2.01. When using a modem, highest data transferrates can be achieved when external noise is reduced as much as possible.To reduce unwanted noise, consider the following:

Make cable runs as short as possible. Seriously consider using CAT-5 communicationscable (10BaseT ethernet cable).
Route cables as far away from other wiring (house wiring, doorbell, cableTV, etc) as practical. If the telephone wire must cross another wiringsystem, cross at a 90 degree angle. A telephone wire running parallel andnear to another wiring system can receive inductive interference (“crosstalk”)from that other wiring system, which will degrade modem performance.
Make sure you have plenty of Doritos and Coke available when you have yourcomputer guru (a 13-year-old kid, in most circumstances) pay you a visit.
Many of these same principles apply to ISDN (a high-speed, multiplexingtelephone line), which itself is beyond the scope of this FAQ.


SECTION 3: Voltages

3.01: What is ring/tip/sleeve?
A: Look at the plug on the end of your stereo headphones (my apologiesif you are listening to your favorite CD). You will see something likethis:
| |______________
========| TAIWAN |_________|_|__>
|____________| ^ ^ ^

This is known as a “Phone plug.” The telephone companies used these(1/4″ in diameter) in the patch bays that the operators used to usewhenconnecting you to “CHicago 17” or something like that. You will noticeit has a tip (T), a ring
