Assembly Language

Assembly is one of programming languages. It's the closest form of machine's language. When we learn about C programming language, or Pascal, we still use the language that uses human language, especially English. The instructions are, if-then-else, while-do, for-to-do, etc. In Assembly, we don't use it anymore(maybe a little, but the syntax is completely different). We can see clearly how the machine works in this language, like moving memory, decreasing or increasing accumulator, using registers, I/O ports, etc.

I use Pinnacle to compile and simulate the program.
The Pinnacle software can be downloaded in :
here
The 8051 Assembly Language Manual can be downloaded in :
here

Common instructions in Assembly :
DJNZ(Decrease and Jump if Not Zero)
CJNE(Compare and Jump if Not Equal)
SJMP(Short Jump)
MOV
RL,RR(Shift Left, Shift Right)

This is an example :
ORG 0H

START:
MOV A,#0FEH
MOV R3,#008H
CALL LAGI
MOV R3,#004H
CALL SAPI
MOV R3,#004H
CALL KUDA
CALL WOW
SJMP START

LAGI:
MOV P1,A
CALL DELAY
RL A
DJNZ R3,LAGI
RET

SAPI:
CALL DELAY
MOV P1,#0FFH
CALL DELAY
MOV P1,#000H
DJNZ R3,SAPI
RET

KUDA:
CALL DELAY
MOV A,#11110000B
MOV P1,A
CALL DELAY
MOV A,#00001111B
MOV P1,A
DJNZ R3,KUDA
RET

WOW:
CALL DELAY
MOV P1,#01111110B
CALL DELAY
MOV P1,#10111101B
CALL DELAY
MOV P1,#11011011B
CALL DELAY
MOV P1,#11100111B
CALL DELAY
MOV P1,#11011011B
CALL DELAY
MOV P1,#10111101B
CALL DELAY
MOV P1,#01111110B
RET

DELAY:
MOV R0,#05H
ULANG:
MOV R1,#0FEH
ULANG1:
MOV R2,#000H
DJNZ R2,$
DJNZ R1,ULANG1
DJNZ R0,ULANG
RET
end


Just copy this program and save into *.asm and compile in Pinnacle. Simulate this using "play" button and view the ports from menu bar.

This program can be downloaded into a MCS-51 chip, using a downloader circuit. This is the result of the program above.



This is the schematic of the circuit :

Overclocking, The Basic

Today we will tell you about overclocking your PC system. Overclocking will cause your PC components like CPU, memory, and GPU or Graphic Card to run faster than before. For example the default clock speed of your CPU is 2.4 Ghz, after overclocking your CPU can run at 3.2 Ghz clock speed resulting greater performance of your CPU.

The most question we heard about overclocking is, "Can overclocking damage computer hardware?". Then we said the answer can be yes or no. Usually, temperature is our enemy when we want to overclocking our system, because this is the main reason of hardware damage in overclocking and system instability. But if you properly monitoring your system temperature with additional CPU cooler, good PC casing with good air ventilation, etc, then it will no problem to overclock your system.

The purpose of overclocking is to gain more performance from your system in daily computing, productivity, and gaming. With overclocking you can get the most out from your system with little additional cost and get the same performance with more expensive system.

Things you must notice in overclocking :
1. Your CPU specs ; to determine how far you can push it. for example I got a Q6600 @ 2.4 Ghz, so in air cooled, 3 Ghz to 3.2 Ghz is great. or maybe E7500 @ 2.93 Ghz, you can push it to 3.6-3.8 Ghz on air.
With water cooling, you can push it more..!

2. FSB (Front Side Bus), CPU multiplier, Memory RAM speed ; this gotta be difficult to understand, but we will try to explain it as simple as we can...
So here's the example.... Q6600 @ 2.4 Ghz , 1066 Mhz FSB , 9x multiplier (all in default condition)
In this case, FSB in CPU's spec = 4 x actual FSB.. So 1066 Mhz in CPU's spec, then the actual FSB is 266 Mhz... ( 1066 / 4 ).
So what actual FSB for? combined with CPU multiplier, in this case is 9x, then actual FSB * multiplier = CPU clock speed. -> 266 Mhx * 9 = 2400 Mhz

Okay, and what memory RAM speed for? the memory speed is the maximum actual FSB you can reach for overclocking. For example PC6400-DDR2, with 400 Mhz speed memory per dimm. So with this type of memory you can raise your actual FSB to 400 Mhz. Try to get 1:1 ratio between memory speed and actual FSB, because it's usually more stable and you get the full bandwidth memory transfer from RAM to CPU.

Okay, how can I know if my system is stable or not? You can test your CPU stability with CPU torture program like Prime95 to stress all of your CPU cores. Usually people stress their CPU about 18 hours to see if the system are stable enough and the temperature of the system are in normal state.
When testing you system got blue screen or freezing, then check the temperature first. When the temperature is normal so it's time to raise your CPU and system voltage which can be raised from the motherboard's BIOS. try to raise it about 0.1 or 0.125 for the voltage to make sure you are not overvoltage it and damaged your hardware. For safe temperature and voltage can be found on the internet, but I will try to find the links for you later.

Overclocking GPU is more simple than overclocking your CPU. Simply download rivatuner and install it. And inside the rivatuner, you can raise your core speed, shader speed, and memory speed of your GPU. You can also set the fan speed, monitoring your GPU temperature and many more. I will try to post an article to show you how to use Rivatuner for the first time.
To test your GPU, usually people test it with 3D Mark 06, a very useful program to benchmark your system performance and also to test the stability of your system. If you can pass all the test without error, then usually your system are stable enough.

That's all from us, if you are not understand enough you can always ask us via e-mail, we will be happy to answer your question.

James Cameron's Avatar Hands-On

Based on James Cameron's upcoming sci-fi blockbuster of the same name, Avatar puts you in the shoes of Ryder, a signal specialist. Ryder is a soldier in the employ of the Resources Development Administration, and he has been sent to the lush moon of Pandora to protect its mining operation. Unfortunately, this process is destroying the native habitat of Pandora, which brings the RDA into conflict with the Na'vi, a species of indigenous, 10-foot-tall, blue-skinned warriors. Avatar gives you the chance to play as a human and a Na'vi, thanks to the ability to transfer your consciousness to a hybrid clone known as an avatar.



Early on in the game you have to choose between playing as a human or a Na'vi, and this branching storyline gives you two very different experiences thanks to each species' unique weapons, skills, and abilities. The RDA campaign is essentially a third-person shooter featuring loads of heavy firepower, whereas the Na'vi campaign's gameplay is action adventure with rudimentary, yet brutally efficient, weapons, such as maces, swords, and bows and arrows. As an RDA soldier, you have access to a high-tech arsenal that includes assault rifles, machine guns, and shotguns. You also have four special skills that you can use to turn invisible, to sprint, to repel enemies for a short period, or to restore some health. The cooldown periods are short, and these skills become vital to surviving Pandora's dangerous flora and fauna. Traversing through the forbidding jungle is risky at the best of times, and thankfully we were able to use a dune buggy and motorboat to travel between locations. In addition to introducing you to the game, weapons, and vehicles, the first few levels give you a taste of what your career as an RDA soldier on Pandora might be like, with glimpses of some of the more advanced military hardware, including helicopters and mechs.
It seems Ryder has been personally assigned to Pandora by a local RDA commander called Falco, and after five long years in hibernation during the journey, you finally touch down on the moon at the RDA's main compound, called Hell's Gate. The base is under imminent attack by viperwolves--nasty canines that can easily rip a man to shreds--and it's not long before you get the pleasure of using a mounted turret to thin out their ranks. Falco reveals that there's a mole within the RDA who's feeding intel to the Na'vi, and he sends you off on a mission to the front-line Blue Lagoon base to find out more.

Once we arrived at Blue Lagoon, we got a chance to see what it's like to be a Na'vi through the RDA's avatar program. In addition to giving the RDA forces the Na'vi's physical prowess, avatars allow the RDA forces to explore Pandora's unbreathable environment without the need for a gas mask. Within a few moments of playing as a Na'vi, you're instantly aware of their benefits. For a start, Na'vi are able to jump much higher than humans and perform an extremely fast dodge move thanks to their 10-foot frame and athletic ability. Na'vi also have slightly different special skills to the RDA, and rather than having a skill that repels wildlife, you can perform a powerful ground stomp that damages nearby enemies instead.
While it essentially plays as an action game, Avatar is imbued with some role-playing elements. You earn experience points for killing, collecting items, and completing objectives, and these automatically unlock more-advanced weapons, skills, and armour as you progress. In addition to earning experience points, the other RPG element in the game is that your progression is through completing quests.. There are also additional side quests that you can complete at your leisure, such as collecting culture samples from native plants.


James Cameron's Avatar features an intriguing story,
the ability to play as two distinct species, and some great graphics that show off the lush, exotic moon of Pandora. The game is hitting all major platforms in early December, just in time for Avatar's big-screen debut.

Blizzard's StarCraft II Beta is Delayed

A recent interview conducted during a Russian games convention reveals that the beta will be delayed.
Wondering what the heck happened to those StarCraft II beta invites? After all, it's late 2009 as Blizzard originally promised, and so far there's no word about its impending release. Unfortunately, it doesn't look as if the beta will make an appearance in 2009 after all according to Blizzard producer Chris Sigaty.

In a recent interview with Russian website Goha.ru held during the three-day games expo IgroMir, Sigaty said that the beta won't make an appearance until 2010, and then refused to mention any additional info, saying that Blizzard isn't discussing dates. In fact, the remaining portion of the interview regurgitated common StarCraft II knowledge stemming from BlizCon 2009: offline play is possible but no achievements will be acquired, etc.

Based on VG247's November 5 article, Blizzard plans to release the first StarCraft II installment during Q2 2010, backing up the company's "first half of 2010" comment made during Blizzard's Q3 financial call to investors. But with the beta now knocked back into 2010, it's possible that the game may be smacked back a few extra months on the calendar too, making it a Q3 release instead. Hopefully that's not the case.

Retrieve Windows Live Messenger 2009 Standalone Individual Setup Installer (MSI) from Web Download


Microsoft has made Windows Live Messenger (WLM or previously known as MSN Messenger) as part of the product suite of Windows Live package, and no longer provide standalone individual setup installer for user to download and install just Windows Live Messenger itself. The story is the same for the latest public beta for Windows Live Wave 3, which includes Windows Live Messenger 2009.

As usual, user download the unified Windows Live Installer which contains installation files for all software programs inside the Windows Live products, such as Windows Live Writer, Windows Live Mail, Windows Live Toolbar and etc. Most of the programs other than WLM is not needed, yet Microsoft forces user who wants to backup the installer or install WLM on not connected offline PC or distribute the program across corporate network to download the massive 100 MB plus integrated full installer, namely wlsetup-all.exe.

The worst part is that the wlsetup-all.exe, which has all the installation files, cannot be uncompressed, unpacked or extracted into separate .MSI installer for each individual software. While the web installer, wlsetup-web.exe does not have the .MSI packaged in as it will download the required .CAB off the Internet.
For those who insist on want to grab and retrieve a copy of individual stand-alone Windows Live Messenger 2009 setup installer, which can be used to install WLM anytime on any computer without waiting for downloading, use the following trick to get the “Messenger.msi” file.
  1. Download Windows Live Installer from download.live.com.
  2. Install or upgrade the Windows Live Messenger to latest version.
  3. Open Windows Explorer, and set it to Show hidden files and folders and show protected operating system files (uncheck the tick for Hide protected operating system files) in the View tab of Folder Options.In Windows Vista, run Windows Explorer as Administrator, and user may requires to take ownership and gain full control permissions for the folders below before able to access them.
  4. Browse to \Program Files\Common Files\Windows Live\.cache\ folder.
  5. There will be a lot of folders made up of 15 characters and numbers. Locate Messenger.msi file inside one of the folder. Messenger.msi is the individual separate standalone setup installer for Windows Live Messenger 2009, which can be backed up or copied to another location. Do note that the Messenger.msi and other Windows Installer Package retrieved this way is silent installer. Tip: %ProgramFiles%\Common Files\Windows Live\.cache\cache.ini file contains the paths of all Windows Live software products downloaded or installed on the computer.
  6. If you have any problem with Windows Live Messenger after installation using the standalone individual installer Messenger.msi, try to install the following 3 programs too, all of which in different sub-folders inside the .cache directory. Contacts.msi (Contacts)
    dw20shared.msi (DW 2.0 Client)
    crt.msi (Microsoft Visual Studio Runtime)

    Tip: Contacts.msi is a must to avoid or fix 8000FFFF error.
After grabbing the Windows Live Messenger standalone silent installer, optionally user can uninstall the Windows Live Suite (all programs) from Control Panel, and install Messenger.msi (and Contacts.msi too) again to get rid of all other Windows Live components except WLM9, saving time and bandwidth in future installation.
The trick also also work for all other Windows Live products such as Windows Live Sign-In Assistant (wllogin.msi), Windows Live Writer, Windows Live Mail ,Windows Live Toolbar, Windows Live Photo Gallery, Windows Live Family Safety, Segoe UI Font, Windows Live Call and Microsoft Office Outlook Connector.

Dragon Age : Origin Gameplay Review


When was the last time you felt totally lost in a fantasy gameworld? When was the last time you played a game with such a well-crafted and enjoyable story that you knew you’d remember it for a long, long time? Dragon Age: Origins is that kind of game, so rich and involving that you are powerless to resist its wiles and whims, so touching and triumphant that your mind and heart will be moved. In the fictional land of Ferelden, you meet memorable characters and fight for a cause you believe in, and it's this backdrop that makes developer BioWare's newest role-playing game so extraordinary. Dragon Age is more than a well-crafted story, however: It's a lengthy, intricate, and thoroughly entertaining adventure that's easy to fall in love with.
Dragon Age's plot, which deals with the impending invasion of a horde of demonic creatures called the darkspawn, isn't where the story's biggest surprises lie. The shocks, the joys, and the disappointments spring from the repartee among a number of remarkable characters; they lurk within books of lore and stories of martyrs; and they burst forth during spine-tingling moments when you must choose from a selection of difficult choices that affect the tale's direction--and the way your associates interact with you. Ferelden is a colorful and fascinating kingdom that takes enough cues from well-known fantasy tropes to be familiar, but bends enough conventions to feel original. Dragon Age features dwarves, but their caste-based society and the social paragons that rise above it twist the norms enough to keep you intrigued. Mages remain under the constant watch of templars, a restriction that doesn't sit well with those who view such policing as virtual slavery. The role of religion in human circles is of particular note. Chantries provide refuge to those worshiping the all-powerful Maker, and chanters recite the holy word near their houses of prayer. But lest this world sound too serious, don't despair: One such disciple slides food references into her chant, and a few dwarves warn you not to fall into the sky. Small, humorous touches like this are plentiful. Even if you aren't the literary sort, Dragon Age may inspire you to read every note, every character bio, and every creature description, thanks to the richness of the world and the consistency with which it's presented. 


You'll learn even more from the companions who join you, and you'll grow to care about them on your quest for glory. There's Morrigan, the cynical apostate mage bound to your cause for reasons that become clear only late in the journey; Sten, the strong, silent type who isn't so quick to reveal his innermost thoughts; and Zevran, a darkly mischievous would-be assassin with a wild streak and a playful disregard for the law. There are others too, including Alistair, a wisecracking, vaguely insecure member of the Grey Wardens, an elite group of champions that recruits you early on. Great dialogue and fantastic voice acting make these characters leap off the screen as if they were real friends, and the way they interact with one another feels authentic. Morrigan and Alistair banter about the role of templars in the lives of mages, and the sweetly devout Leliana tries to communicate with your trusty canine cohort in some amusing exchanges. You may even develop a romance (or two) before all is said and done. The course of love isn't always a smooth one, though it can be a bit steamy, in a PG-13 sort of way.


Relationships must be nurtured; in the world of Dragon Age, love doesn't develop at first sight. Rather, you must improve your standings with available party members by giving them gifts and fulfilling quests in ways that please them. Doing so opens more dialogue options and may even reward you with unexpected gifts beyond the private pleasures of your tent. Your personal relationships aren't all you need to worry about when facing a difficult decision, however. On significant quests, you'll encounter complex choices that force you to weigh the risks against the rewards, even as you try to stay true to your own vision of your character. Are werewolves heartless killers, or is there a method to their madness? Should you wholeheartedly embrace a political candidate, or will some unexpected information have you playing double agent--or just killing the opposition? Such open-ended quests have become staples in many similar RPGs, but few make these decisions feel so momentous. The anxiety that results when you encounter important choices is a result of superb writing and character development: When you care about your destiny, decisions have more weight.
Even Dragon Age's initial moments present important decisions that affect how your adventure plays out. You'll customize your own avatar's look from a variety of presets, but more importantly, you'll choose a race and class. The choices may seem initially limited, but your options eventually expand. Later, you can choose up to two subclasses once you reach the necessary level requirements, and there are a few different means of unlocking additional skill trees. Your initial race and class choices don't just determine the kinds of skills and spells you will have access to, however; they influence how the first few hours of the game progress. You will experience one of six different "origin stories" that follow the events that lead you to the elite Grey Wardens. Every origin story leads to the same place, but that doesn't mean you leave these events behind for good. Characters you met early on will cross your path again, and crucial moments of your origin story will continue to haunt you. The varied origin stories not only provide plenty of replay value, but allow you to see familiar characters from a different angle. A prisoner you meet within a dank dungeon may not have much impact on you if you are playing as a Dalish elf, but if you play as a human mage, this encounter is a bittersweet reunion.


You aren't a lone adventurer, however. You can take up to three companions along with you, and eventually you will meet more willing (or unwilling, as the case may be) darkspawn slayers. You can switch out party members back at your camp or in other friendly areas. Party members you don't use will remain at camp, though they thankfully level up even when you don't take them along. Your comrades aren't just AI-controlled henchmen; you can take full control of any party member at any time, though how you do so depends on the platform. PC owners get the most versatile and rewarding experience in this regard. You can zoom the camera in to a close third-person view when exploring and conversing with non-player characters, or pull the camera back to a tactical view, which makes it a breeze to quickly and easily micromanage every spell and attack, in true Baldur's Gate tradition. On consoles, you always view the action from behind a single character, and you use a shoulder button to switch among them. It's a great way of experiencing the buzz of battle, though occasional pathfinding quirks are more apparent in the console versions, simply because you experience the action from a single perspective at a time, rather than while managing four characters simultaneously. 


If you've played a BioWare fantasy RPG in the past, you'll feel right at home with the combat system. By clicking on your target or pressing the attack button, you don't just swing a sword, but you approach your target and queue up your attack. Once your party has gained access to a good number of spells, stances, and skills, battlefields explode with bright colors and raucous sound effects, and it's a lot of fun to switch back and forth between party members, managing your abilities and taking advantage of various spell combos to wreak havoc. There are dozens of different types of enemies to slice up, from giant spiders and darkspawn, to ghosts and walking trees, to demons and, of course, dragons. Allies will join you in the biggest battles, and the best of these, particularly those toward the end of the game, are thrilling. On the PC, they're particularly challenging, and many battles benefit from frequent pausing and tactical thinking, so that you can queue up attacks across your entire party. The same battles on consoles are noticeably easier.
Nevertheless, the Xbox 360 and PlayStation 3 versions have their challenges, and no matter which platform you choose, you can customize your cohorts' AI behavior to be more effective in battle. Using the tactics menu, you can set characters up to drink potions when their health gets low; have Morrigan cast helpful crowd-control spells when enemies are clustered together; and program sturdier characters to draw enemies' ire when more vulnerable party members are under attack. As you level up, you will earn additional tactics slots, allowing you to implement even more intricate actions. You can also apply basic behaviors to your team members, making them more aggressive or defensive, and you can switch them around on the fly if an experimental custom tactic isn't working as you intended. When things come together as you plan--such as when Morrigan freezes a hurlock in place and Alistair smashes it to smithereens--battles are even more rewarding.
All of these elements coalesce wonderfully, making for a memorable and exciting adventure that keeps you on the move. The flow of loot and pace of leveling are both highly satisfying, and because you have four active characters to consider (in addition to others back at the camp), you spend a lot of time poring over armor and weapon choices. The tempo is even quicker than the Dungeons & Dragons games that preceded Dragon Age, thanks to important tweaks that minimize downtime. For example, you do not need to rest between encounters to replenish your health and recharge your spells. Instead, health and stamina are replenished quickly once the skirmish ends, allowing you to string encounters together without unwanted breaks in between. Should a party member fall during battle, he or she will be resuscitated once the battle has ended, albeit with a stat penalty applied (though it can be cured with an injury kit). These factors, and more, give Dragon Age an excellent sense of forward direction. 


All the spells, tactics, and skills sound like a lot to organize, but the interface does a great job of helping you keep track of things. The PC interface is brilliant, letting you browse through your inventory and tweak your quickbars quickly and easily. The console versions do a surprisingly great job as well, making it simple to sort through your quests, and to queue up actions while battle is paused. One particularly useful feature is the ability to identify inventory items as trash and sell them all with a single button press once you're back in town. There are some console-specific interface irritations that could have been cleaner, however. For example, identifying new codex (that is, lore) entries can be troublesome, because the list doesn't scroll down until your highlight cursor reaches the bottom of the window. As a result, you can't always distinguish new entries from old ones, which is an issue that doesn't plague the fantastic PC interface. The consoles' radial menu, on the other hand, is an excellent way of letting you access every battle skill, and it works somewhat like the similar interface in Mass Effect--albeit with a few more layers.
The differences between versions aren't limited to the interface. Dragon Age doesn't look amazing on the PC, but it's an attractive game nonetheless. Zooming from an isometric view to a third-person perspective is slick, and while environments don't hold up quite as well when viewed up close, they're consistently lovely when viewed from above. On the flip side, the Xbox 360 version looks positively disappointing. Textures are highly compressed and colors are washed out, though the upside is that this version maintains a smoother frame rate than on the PlayStation 3, where things might get jittery when swiveling the camera around. The PlayStation 3 version features higher-quality textures than those on the Xbox 360, better color saturation, smoother facial animations, and shorter load times. Minor visual hiccups, like corpses that disappear and reappear, are a bit more common on the PS3, however. The PC version is the superior experience, but if you're choosing between the two console releases, the PlayStation 3 has the upper hand. Some minor glitches are shared between the console versions, however, such as rare occasions when the soundtrack or voice-overs disappear. We also ran into a few quest malfunctions that could be replicated on all three platforms, though they were relatively minor and did not interfere with the progress of the main quest. 
No matter which version you choose, however, there are plenty of audiovisual details to note. In many ways, Dragon Age looks and sounds like other high-fantasy games, but while the towers, forest paths, and underground caverns are what you've seen before, the art style is attractive, and a few sights, such as an underground dwarven city, are particularly eye-catching. Character models don't exhibit Mass Effect-level expressiveness, but they look good and animate smoothly enough. Also of note are the splatters of blood that appear on your party members after battle. It's a nice idea, but the splotches look like they've been splashed across you with a paintbrush. The crimson stains are a cool thematic touch, however, because blood plays an important role in Dragon Age. The sound effects are excellent, console glitches notwithstanding, and the soundtrack, while typical for a fantasy game, swells and murmurs at all the right moments.
Few games are this ambitious, and even fewer can mold these ambitions into such a complete and entertaining experience. You might spend 50 or more hours on your first play-though, but there are so many paths to follow, so many details to uncover, and so many ways to customize your party that you'll want to play again as soon as you finish the first time. PC owners even get an extra dash of depth via the downloadable toolset, which lets you create new levels, spells, skills, and even cutscenes. But any way you slice it, here's the fantasy RPG you've been waiting for, the one that will keep you up late at night, bleary-eyed, because you have to see what happens next. Like the best fiction, Dragon Age will sweep you up in its world, so much so that when you're done, you'll want to experience it all over again.

How to Use Seven Segment

Some of you might think that this is actually not important, because you can try this yourself. But, do you know how many volts do you need to light a LED? Do you know about the current limit that will light a LED without breaking it? Of course you can try this yourself, but some of people are just too lazy to do this. :P

Now, what are the limits? LED is a diode that emits light. The LED in seven segment is just a small LED, so it can’t take too much power from the source. A common LED in seven segment only needs approximately 3 V and a current limit of 20 mA. If you have a 5 V battery or 4.5 V battery, you should insert a resistor in the circuit to prevent a current overflow. Usually, the resistor is about 330 Ohm. The LED should be bright enough to be noticed.

How can you light the LEDs? You just need to set a battery and a 220 Ohm resistor with the LED. The positive side of the battery should meet the anode of the seven segment and the negative side of the battery should meet the cathode of the seven segment. If you are using common-cathode seven segments, there are 8 pins of anode that can be paralleled to light every segment of the seven segment. We will give you a simple circuit below.

Core Temp , CPU temperature monitoring utility software

Core Temp is a compact, no fuss, small footprint program to monitor CPU temperature.
Now Windows Vista and Windows 7 ready! (x86 and x64)


 
The uniqueness of it is that it shows the temperature of each individual core in each processor in your system! You can see in real time how the CPU temperature varies when you load your CPU. It's also completely motherboard independent.


Intel and AMD recently published detailed, public information about the "DTS" (Digital Thermal Sensor), which provides much higher accuracy and more relevant temperature reading than the standard thermal diode sensors do. (How does it work?).


This feature is supported on all Intel Core and Core 2 based processors as well as the whole AMD's Athlon64 line of CPUs. For a full list of supported CPUs see the CPU Support List.
Note: AMD Phenom is supported, but it does not report absolute temperature. More on this in How does it work?.



Core Temp also has a logging feature, allowing a user to easily record the temperature of his processor(s) over any period of time, then the data can be easily transferred into an excel datasheet for easy graphing.


Core Temp works on Windows 2000, XP, 2003 and Vista (both 32bit and 64bit versions).
Thanks to CoolIT Systems for providing a digitally signed Core Temp driver which now works on all Vista versions.

Basic Digital Display : Seven Segment

Seven segment is a display component that have seven segments(actually eight). Each segment represented by a LED. Seven-segment displays are widely used in digital clocks, electronic meters, and other electronic devices for displaying numerical information. Beside seven segment, there are fourteen-segment and sixteen-segment, usually used for making an alphanumeric character.

The segments of a 7-segment display are referred to by the letters A to G, as shown to the right, where the optional DP decimal point (an "eighth segment") is used for the display of non-integer numbers.




The animation to the right cycles through the common glyphs of the ten decimal numerals and the six hexadecimal "letter digits" (A–F). It is an image sequence of a "LED" display, which is described technology-wise in the following section. Notice the variation between uppercase and lowercase letters for A–F; this is done to obtain a unique, unambiguous shape for each letter.


As shown to the right, a seven-segment has ten pins under the display. Based on the pins, seven segment can be divided into 2 kinds, common cathode and common anode. A common anode seven segment consists of 2 pins of anode and 8 pins of cathode. Each cathode pin lead to cathode part of each segment(LED) on the display. Both of anode pins are short-circuited, and lead to anode part of each segment(LED). A common cathode seven segment is the opposite of a common anode seven segment. There are 2 pins of cathode and 8 pins of anode.

The image on the right is the pins of the seven-segment. X is the common pin, if it is a common anode, then X is anode, and vice versa. The other pins are the complement of the common. For the common anode, to turn the LED on, we must place the plus sign of the battery on the common and the minus sign of the battery on other pins.

CPU-Z | CPU and System Identification Software

CPU-Z is a freeware system profiler (system monitor) application for Microsoft Windows (for all versions from 95 on) that detects the central processing unit, RAM, motherboard chipset, and other hardware features of a modern personal computer, and presents the information in one window. CPU-Z is more in-depth in almost all areas than the features that a Windows OS provides to identify various hardware components, and is thus needed to identify certain components without opening the case, especially the core revision and RAM clock rate. It has an unusual ability to directly detect hardware features, especially the ability to access, read and display the SPD data from memory modules. The ability to document clock speed makes it an important tool for motherboard overclockers, as a way of proving the CPU speeds achieved by various experiments.

Microsoft Office 2010

Microsoft Office 2010, codenamed Office 14, is the successor of Microsoft Office 2007, a productivity suiteMicrosoft Windows. Extended file compatibility, user interface updates, and a refined user experience are planned for Office 2010. With the introduction of Office 2010 a 64-bit version of Office will be available for the first time. It will be available for Windows XP SP3, Windows Vista and Windows 7. Furthermore, Office 2010 will mark the debut of free online versions of Word, Excel, PowerPoint, and OneNote, which will work in popular web browsers (Windows Internet Explorer, Mozilla Firefox, Google Chrome, and Apple Safari), although, surprisingly there is no support for the Opera browser. Microsoft has confirmed that it will be released during spring 2010, and a public beta to show up in November 2009.


Development started in 2006 while Microsoft was finishing work on Office 12, released as Microsoft Office 2007. The version number 13 was skipped because of the aversion to the number 13. It was previously thought that Office 2010 (then called Office 14) would ship in the first half of 2009; however Steve Ballmer has officially announced that Office 2010 will ship in 2010 with a more specific countdown (days) provided at office2010themovie.com

On April 15, 2009, Microsoft confirmed that Office 2010 will be officially released in the first half of 2010. They announced on May 12, 2009 at a Tech Ed event, that Office 2010 will begin technical testing during July and was publicly released to those who signed up to test on 07/08/09. It will also be the first version of Office to ship in both 32-bit and 64-bit versions.

According to an article published in InfoWorld in April 2006, Office 2010 will be more "role-based" than previous versions. The article cites Simon Witts, corporate vice president for Microsoft's Enterprise and Partner Group, as claiming that there would be features tailored to employees in "roles such as research and development professionals, sales persons, and human resources." Borrowing from ideas termed "Web 2.0" when implemented on the Internet, it is likely that Microsoft will incorporate features of SharePoint Server in Office 2010.
Microsoft Office 2010 will implement the ISO/IEC compliant version of Office Open XML (OOXML) which was standardized as ISO/IEC 29500:2008 in March 2008, though will also have the option of implementing as a setting the ISO/IEC compliant version of Open Document Format (ODF) v1.1, beyond 1.0 which was standardized as ISO/IEC 26300:2006 in May 2006
New features are also said to include a built-in screen capture tool, a background removal tool, a protected document mode, new SmartArt templates and author permissions. The 2007 "Office Button" will be replaced with a menu button that leads to a full-window file menu, known as Backstage View, giving easy access to task-centered functions such as printing and sharing. A refined Ribbon interface will be present in all Office applications, including Office Outlook, Visio, OneNote, Project and Publisher. Office applications will also have functional jumplists in Windows 7, which would allow easy access to recent items and tasks relevant to the application.

Electronic Symbol

An electronic symbol is a pictogram used to represent various electrical and electronic devices (such as wires, batteries, resistors, and transistors) in a drawing of an electrical or electronic circuit. These symbols can (because of remaining traditions) vary from country to country, but are today to a large extent internationally standardized. Some symbols (such as those of vacuum tubes) became virtually extinct with the development of new technologies.

The Top 10 Most Annoying Enemies

We’ve all run into them: those monsters that make us want to pitch a controller through the wall. Maybe it’s an annoying laugh they emit after they dump you into a bottomless pit for the thirtieth time. Maybe it’s an unavoidable attack that deals an obscene amount of damage. Or maybe it’s just some downright psychic precognition. Whatever form it takes, these enemies are downright ANNOYING! This list is to celebrate some of the worst of those foes who are responsible for all those snapped CDs, teeth-mark-pocked controllers and TVs with holes in them. Note that this list does not cover annoying bosses; that’s for another day.

#10: Toxomister - Sonic & Knuckles (GEN)

In spite of a very gentle difficulty curve, the Sonic series actually has a few really annoying enemies and traps. The Spike-Pit-Of-Unnecessarily-Slow-Super-Sonic-Death from Sonic the Hedgehog 2 and the notorious Barrel of Doom from Sonic 3 both deserve mentions here, but are ultimately disqualified from the list for not being enemies. Instead, we open with Toxomister, a rather vexing enemy from the series’ last 2D Genesis entry. An enemy from the Lava Reef Zone, Toxomister, at first glance, appears non-threatening; it’s really just a metal pole with an eye on the top of it. Unfortunately, it has the ability to spit out a toxic cloud that Sonic or his friends can easily run into in a moment of high speed absent-mindedness. But this cloud doesn’t kill you! No, that would be far too simple and unannoying... Instead, it slowly (VERY slowly) drains your rings, one at a time. In addition, it greatly decreases your running speed and jumping height, making continuing the level almost impossible. The only way to get rid of the cloud is to die, wait until it has drained 100 rings from your health, or kill the Toxomister that poisoned you (easier said than done since, while under the toxic cloud’s effects, you cannot jump high enough to hit the jerk’s weak point). While not really all that dangerous, Toxomister is certainly very annoying and he gets #10 on the list.

#9: Thieves - Fire Emblem series (various)

Fire Emblem, a Nintendo SRPG series recently imported to Western shores, is not a game series for the careless. The AI is relentlessly unforgiving of any mistakes you make and if you lose a character, they are gone forever. Dead. Permanently. This means that even seasoned veterans of the game will be extremely careful with many of their units, as a carelessly placed mage could easily fall victim to a rampaging enemy berserker and even your best character is not immune to an unlucky critical hit from a swordsmaster. But the dubious distinction of “most annoying enemy” of the series has to go to the thieves. These diabolical sneaks suddenly appear at the worst possible time and head straight for any treasure chests on the map (said chests are usually packed with REALLY nice items). As soon as they pilfer the chest’s contents, they will take their leave of the battle and run off the map, taking their loot with them. If you’re already hard pressed fending off the enemy, these bandits will push your blood pressure through the roof as you realise you have no units in position to stop their pillaging and sending a cavalry unit over that direction in the forlorn hope of catching them before they escape could spell disaster, either for your battle lines or for the cavalry unit in question. Once again, not very dangerous, but REALLY annoying!

#8: Wallmasters - The Legend of Zelda series (various)

Wallmasters are one of the oldest Zelda enemies around. Their debut was in the very last room of the first dungeon of the original Legend of Zelda game. They first appeared as a set of disembodied hands that drifted out of the walls and tried to grab Link and drag him back into said walls, returning him to the dungeon’s first room. The Wallmasters (and their distant cousins, the not-nearly-as-annoying Floormasters) returned for subsequent Zelda games, now making their abode on the ceilings of various dungeons. In spite of their new home, their role remains unchanged: grab Link and spit him back to the very beginning of the dungeon, forcing him to take a sizable detour and retrace his steps back to wherever he was. In long dungeons, this is already enough to set your teeth on edge, but with the 3D Zeldas the Wallmasters have expanded their repertoire to include scaring the living crap out of unwitting gamers. The only warning one gets of an imminent Wallmaster attack is a dull, growling roar and a growing shadow appearing underneath Link; if the player doesn’t immediately dodge or switch into a first person view to try and spot the beast, a giant, gnarled, discoloured hand will drop from the ceiling, giving the player a mild heart attack and heartlessly sending them back to the dungeon’s entrance. Wallmasters: scaring the crap out of little kids and generally being annoying since 1987.

#7: A-wings - Star Wars: TIE Fighter (PC)

The first entry on this list that’s actually dangerous, the A-wing was a nasty little foe and the hardest rebel starfighter you could come up against in the original TIE Fighter (sans expansion packs). For those not well-versed on their Star Wars lore, the A-wing is a Rebel interceptor, a fast, dagger-like ship armed with laser cannons and concussion missiles and with engines unmatched by anything in the Empire’s basic arsenal. In TIE Fighter, these little monsters were blindingly fast and incredibly manoeuvrable, capable of outrunning and outflying every player ship until the TIE Advanced found its way into the storyline. This incredible speed, combined with its compact chassis, made the A-wing incredibly hard to destroy. Even the anti-starfighter concussion missiles, usually a guaranteed kill, were useless against the A-wings, which would nimbly evade the missiles until they self-destructed. Not only were the A-wings difficult to kill, they were also dangerous, as the concussion missiles THEY packed could shred your unshielded TIE faster than you can say, “I’m your father!”

#6: Bothan Spies - Star Wars: Battlefront II (PC)

The highest selling game-series of the Star Wars franchise also introduced one of its most annoying enemies: the Bothan Spy. The Battlefront games are massive-scale FPSes, featuring combat between you and your several-hundred strong allies vs. the several-hundred strong enemies. You truly are a drop in the bucket in this game, which is probably the only reason why the Bothans are as aggravating as they are. The computer-controlled Bothan Spies are annoying in several ways: first off, they can turn invisible. If you look closely, you can still see their distorted outline, but most players will be too busy firing an endless stream of shots into the tough-as-nails Wookiees bearing down on them to notice such a subtle hint. When the Bothans get close, they unleash their second nasty surprise: the disintegrator. The small, but incredibly potent gun they carry can drain your health in under a second, turning you from one of the Emperor’s Finest into a pile of dust in the blink of an eye. Usually the first sign an Imperial player gets of a Bothan attack is the whooshing sound of their weapon going off, followed by a red flash of the screen as they abruptly get reduced to their constituent atoms. In light of this new fact I can confidently say that however many Bothans died to bring news of the second Death Star to the Rebellion, they deserved it!

#5: Green Slimes - Odin Sphere (PS2)

Odin Sphere is a criminally underrated 2D sidescroller for the PS2. It features an amazing soundtrack, drop-dead gorgeous visuals and a surprisingly intense difficulty. By far the most annoying enemy of Odin Sphere’s cast was the Green Slime, a relentless and aggravating creature found in the back allies of Titania. See, in order to clear a stage in Odin Sphere, all enemies must be defeated. This includes these little green nuisances. “So what?” you say, “Just kill them and get on with it.” Only one problem: the mini-menaces are immune to all physical attacks. This means you either have to make use of your (extremely limited) magic attacks or have the foresight to stock up on napalm beforehand. And napalm isn’t exactly the easiest material to create. Oh, and if you exit the dungeon to go top up your napalm reserves? You have to do the whole thing again from the very beginning and kill all those green slimes over again. VERY, very annoying!

The Malboro is not only one of the most annoying enemies in the Final Fantasy series, it’s also one of the ugliest. Debuting in Final Fantasy 2, the Malboro looks like a fanged, toothy maw surrounded by tentacles and sitting atop a set of plant roots. What makes the Malboro so feared and so utterly aggravating is its signature attack: Bad Breath. This spell, in most Final Fantasy games, inflicts nearly every negative status effect in the game on every active member of your party. Poison, dark, berserk, sleep, confused... you name it, Bad Breath causes it. This can easily wipe out your party if you’re not prepared. Not only very annoying, but very dangerous to boot.
I was trying to narrow this down to one enemy, but in the end it simply proved to be too arduous of a task. Nearly every enemy in the last levels of Phantasy Star Online is aggravating enough to make the list, so I decided to put them all in one entry to save space. Megid is PSO’s instant death spell and, unless you seriously boost your dark-element defence, it will kill you nearly every time it hits. What makes this worse is nearly every enemy in the last level or two of Episode I and II is packing some variant of the Megid spell and they don’t hesitate to use it. There’s the Ob Lily, with its ability to paralyze its prey before delivering the death blow, the Gran Sorcerer, which can teleport around the room to avoid being hit, the Mericarol and its various cousins who use an area Megid to kill anything near them, the Deldepth who race around the room invincible before popping up to briefly fire off a Megid, the Del Lilly, an even more ferocious version of the Ob Lily, and, of course, the lethal Ill Gill, a reaper who can root you in place, leaving you unable to dodge your impending doom. I could literally fill this list with PSO enemies if I wanted to, as even non-Megid enemies like the Delbiter and the Sinows are worth a mention. If you ever get up to the highest level of Ultimate difficulty in this game, be prepared for a lot of pain and swearing.
A true game for the masochistic, Super Ghouls n’ Ghosts is one of the most difficult games in existence. The unforgiving and relentless difficulty is something you’d expect out of a ROM hack, not an actual published title. But even in this sadistic game, there is an enemy that outshines all others in terms of danger and sheer annoyance factor. That enemy is the Red Reamer, also known as the Red Arremer Ace, Firebrand and the Red Devil. Regardless of what you want to call him, he is truly a force to be reckoned with. When you first come across the Red Reamer, he sits quietly asleep on a ledge in front of you, looking almost peaceful. However, when you get close or try to attack him, he immediately springs to life and leaps out of the way of your attacks. He is close to invulnerable, as he is able to dodge nearly every attack with almost perfect accuracy. If you don’t have the homing arrows or gold armour, he is nearly impossible to take down. The Red Reamer is not quite perfect and if you aim a shot just above his head, he will sometimes fly into it, but his near unbeatable clairvoyance makes him the game’s most annoying (and deadly) enemy bar none. Interestingly enough, the Red Reamer moved on from his role as the mascot of the Ghosts n’ Goblins series and went on to star in his own series, entitled Gargoyle’s Quest. His abnormal precognitive abilities did not join him in this new role, but he will still be forever remembered as “that annoying flying red thing that always kills me on the last level!”
Anyone reading this list who has ever had the misfortune of playing a single player game of Sonic Shuffle is wincing right now. Sonic Shuffle was an interesting experiment on Sega’s ill-fated Dreamcast; often cited as Sega’s version of Mario Party, it used the board game/item collection mechanic, but used cards instead of dice, with each player being dealt a hand of cards they could use to move across the board and battle enemies. This allowed you to more strategically determine your path to the objectives. However, if you didn’t have the card you needed, you could take one of your opponents’ cards instead, which tended to be more of a crapshoot, but would occasionally pay off. Unfortunately, the single player game was plagued by the worst case of psychic AI I have ever seen in over twenty years of playing video games. Although you could not see the computer’s cards, it could see yours and would constantly have the computer characters steal your best cards or the exact one they needed. If there was a “random” spinner to determine who suffered a bad effect or who got to teleport with who, the spinner would ALWAYS land on you, even if you weren’t in the lead. The computer players would go out of their way to make your life miserable and your game as difficult as they possibly could. The whole thing was so completely unfair and teeth-grindingly annoying, it defies belief. If you ever want an exercise in self-restraint, play this game on single player without using mid-game saves and try to win. Also, have some friends nearby to restrain you during your ensuing attempt to throw the Dreamcast out the nearest window.

This is a sample of some of the most annoying enemies gaming has to offer. This list is by no means exclusive and there are certainly more enemies worth mentioning, such as the Like Likes from Zelda or the Teddy Bears from Clockwork Knight. The one nice point to have an annoying enemy is that they are almost as satisfying to beat as a real player-character and sometimes even more so. Hope you enjoyed the list!

Left 4 Dead 2 : Hard Rain Campaign Gameplay

The sky is angry. It's pouring rain, and you can barely trudge through murky, knee-level floodwater. Lightning in the far-off distance signals a worsening storm, and before you know it, a hard wind sweeps by and reduces visibility to a hair above zero. Clearly, things are bad and getting worse--and that's before you bring in the zombies.

This is the type of scene you can expect from Hard Rain, the fourth of five campaigns in Left 4 Dead 2. By now there's a good chance you're familiar with the new setting in this sequel to last year's hit co-op shooter. The development team at Valve has uprooted players from Anytown, USA, and has focused on telling the story of the zombie apocalypse from the point of view of four survivors crossing through the Deep South. The unveiling of Hard Rain comes on the heels of previously announced campaigns, like the daytime New Orleans streets of The Parish, the twisted nighttime fairgrounds of Dark Carnival, and the spooky wilderness of Swamp Fever.



With Hard Rain, the focus isn't so much the setting as it is the nasty weather conditions. Things start out harmless enough. You found your way onto a rescue boat at the end of the previous campaign, but with fuel running dangerously low, your group of survivors has decided to dock and head inland to find a gas station. This quest for diesel begins in a nondescript suburban town as you make your way from zombie-infested backyard to zombie-infested backyard. Aside from having to fight your way through dozens upon dozens of the ravenous undead--an act aided by new melee weapons like the katana, fire axe, and chainsaw--things don't look too bad. There's even a yard sale where VHS copies of '80s comedies have been replaced by ammo caches and silenced Uzis.

Then things go south. Soon that suburban town leads to a series of dilapidated industrial buildings, culminating in a trek through a witch-infested sugar mill. (When we say infested, we mean it. It turns out those witches are attracted to the scent of sugar.) Worse yet, your reward for safely exiting this sugar mill is a blind dash through a sugarcane field with nothing more than a neon gas-station sign peeking up in the distance to let you know you're not running in circles. Think of this scene as a follow-up to the cornfield in Blood Harvest.

It's once you get to the gas station and complete the second chapter of Hard Rain that this campaign's clever design becomes apparent. Rather than head off to a new location, completing the point-A-to-point-B gauntlet of other Left 4 Dead campaigns, you need to retrace your steps and take that gas back to the boat you arrived on. But in the time it has taken to fill up those cans of diesel, what began as a light rain has turned into an outright downpour, resulting in a ground covered in deep pools of water that were only small puddles earlier. Suddenly that quick run through the sugarcane field becomes a terrifyingly slow march through deep water without the ability to see where you're going.

On the run back to the boat, retracing your route step for step means drastically reducing your speed and leaving yourself an easy target for any boss infected waiting around the corner. The best approach is to take the aboveground alternate paths that were there the first time around but you may not have noticed. Catwalks and raised platforms offer a safer but trickier path through the sugar mill, while the best means of quickly making it through the suburban town is to stick to the rooftops and jump from house to house. It's a deviously clever way to take you back through familiar terrain, yet have you totally rethink your path.

There's also a new storm mechanic that will trigger a zombie horde in a scary new way. At certain points, the game's AI director will trigger a sudden increase in storm conditions, which picks up the rainfall and drastically limits your visibility for a short duration--all while sending a new wave of zombies your way. The best strategy during these storms is for everyone to quickly hole up in the smallest building nearby and wait for conditions to pass, because that reduced visibility makes it easy to get separated. It's especially hilarious if you do this with one teammate standing at the doorway to greet every incoming zombie with a revving chainsaw--sort of like the world's least friendly bouncer. If there was ever a melee weapon designed for keeping control of choke points, it's that one.

All this wetness means that fire-based weaponry like Molotov cocktails and the new incendiary round ammo are suddenly much less effective. Thankfully, Valve has seen fit to add a number of new weapons and equipment to help keep you in the game. One that caught our eye was the jar of boomer bile, which lets you play the role of the boomer by attracting the horde anywhere you throw the jar. Want a quick laugh? Throw the bile on the tank and watch his zombie buddies suddenly turn on him. There's also an adrenaline shot to help you run superfast when things get desperate and a defibrillator to revive fallen teammates.

With some persistence and a healthy dose of teamwork, you'll make it to the fifth and final chapter of Hard Rain. Here the team has to turn on the neon sign of a fast-food joint to act as a signal to let the boat know where to dock, but of course that triggers a swarm of common and boss infected that will last for minutes on end. The final battle here is done much like those in the original game, which contrasts to some of the other Left 4 Dead 2 campaigns, such as the Parish, that end in a point-to-point dash to safety instead of the traditional standoff.

The options in this final standoff include hanging out on the rooftop and leaving yourself open to tanks and chargers knocking you down to the flooded ground below, or hanging out in a small room such as the restaurant kitchen in order to hole yourself up closer to the ammo stockpile. Like in any other Left 4 Dead campaign, all the options work; it's just a matter of how well you stick together as a team. That's certainly what we did--right up until the boat arrived and we made a mad dash to safety that left one of our fallen comrades a mere soaking-wet punching bag for the tank. Hopefully you'll be a better teammate than we were when Left 4 Dead 2 is released November 17.
