The Science of Christmas!

Behold, boys and girls. Here are again some cool facts and myths explanation regarding Christmas.

• Thomas Edison introduced Christmas lights to the world in 1880. Might cause a fire on that time because, people put actual candles with flames on their tree.
• It's a law of the universe that your Christmas lights will tangle (entropy), no matter how carefully you packed them away the year before. Physicists have proven that for any cord longer than 2 meters (even 1 meter though), knots are almost mathematically guaranteed. That's because there's only one way for the string to be "untangled" but endless possibilities for it to get fouled up. And putting it up to a straight one is really pain in the ass!
• Santa relies on girl power. Santa's sleigh is pulled by a team of reindeer in full antlers. Male reindeer shed their antlers in the winter. So unless every reindeer of Santa's sleigh is wrong, Santa's reindeer are all female.
• Even if most reindeer can't fly, they do float in water. Their fur traps air, like a puffy jacket. and when they float, they look like a Pokemon! Gonna catch them all!
• Some reindeer really do have red noses, at least some of the time. It comes from lots of blood vessels in their noses which helps them regulate body temperature. Just like i told you last...last...er...
• Santa's sleigh would have to travel 1,300 miles per second for him deliver toys to every child on earth on Christmas Eve. If he were flying an ordinary object with no magic, it would burst into flames from the heat generated by air resistance. If he were a regular non-magical guy, there would be other detrimental effects to Santa himself, too.
• Historical concerned, Santa visits the South Pacific first, then New Zealand and Australia. After that, he shoots up to Japan, over to Asia, across to Africa, then onto Western Europe, Canada, the United Sta States, Mexico and Central and South America. Santa is really fascinating!
• Star of Bethlehem was an actually a rare alignment of planets, several of which occurred between 3 B.C. and 2 B.C. — dates that some scholars think could correspond with the historical birth of Jesus. One such sequence involves the planet Jupiter, flitting back and forth across the star Regulus in Leo and then approaching Venus so that the two appeared as one.
• Virgin birth not just for Mother Mary. Even Komodo Dragons and the Atlantic Blacktip Shark, could birth on their own with out mating. Process known as Parthenogenesis, eggs become embryos without male fertilization.
• Christmas are for birds. People needed to do something during the Christmas holidays that didn’t involve slaughtering thousands of wild birds. Frank Chapman (1864– 1945) was the founder of the annual Christmas Bird Count, the longest running citizen science project in the world to count the birds in Christmas time.

  
And yet...

Although, science-wise, there is a strong argument against the existence of Father Christmas, there is something maths and physics has NOT taken into account.
"If we are to believe Science then there is NO Santa Claus. Or else, if we knew how he did it, then every economy on the world would be onto it. But we don’t.
The thing is Science has omitted to take into account the magic and mystery of the Great Man.
Santa's sleigh is not a time machine, nor a space ship nor a TARDIS (Doctor Who anyone?).
It is a tangible ray of hope powered by our imagination and the dreams of children all over the world.
And that’s why every year Father Christmas brings magic to all of us."


MERRY CHRISTMAS EVERYBODY!!!

How to Reset Toner and Drum counter of Brother HL2140 (and the likes)

Toners and drums of any brands of printer are too expensive. So to cut the company expenses, we do life “hack” of some things.

Below are some instructions for resetting the toner counter if it remains on after you’ve already replaced the said toner. These steps is for HL2140 but already tested on HL2150 and almost similar printers:

• Turn the printer off and open the front cover.
• Hold the “GO” button while turning the printer on.
• All panel lights should now be on. Release the “GO” button.
• Press the “GO” button twice.
• Pause and wait for a 5 seconds.
• Press the “GO” button 5 times and the toner light should turn off.
• Now close the cover.The ready light should be the only light on.

Actually, you could still test or use the previous toner, because it’s not the toner that was already lapse…only its counter.

And here’s how to reset the drum counter:
Having the cartridge door open, press and hold down the white button for about 4 seconds until all the LEDs light up. Once all 4 LEDs are lit, release the button.

Or

Having the cartridge door open, Press the white button 3 times then all LEDs light up. Then close the cartridge door.

On the MFC machines (multi-function) you should be able to get rid of the “end of life” messages as follows:

• Open front door where you access the toner.
• Press the Clear/Back button.
• Follow menu for resetting the different cartridges.

Some have found that the drum or toner message didn't reset even if they already replace both, so here's a way to reset all:

• Open the front door where you access the toner.
• Press the Clear/Back button. You will be shown a dialogue “REPLACE DRUM? 1.Yes 2.No
• DO NOT type in 1 or 2! Instead, type in *00 (i.e. Asterisk Zero Zero) on the keypad and you should be rewarded with “accepted”.
• Close the front door and the end life message should disappear.

If the above procedures don’t work, the manual reset of the cartridge is another option.

Note: please avoid touching the toner roller except at the very ends of its rollers or your hands will full of carbon. You can’t eat having a carbonized hand. :D

There is a plug at the side of the cartridge (see red arrow).

 The cartridge tells the printer that he's already dried up because of this lever. But, when you lift it back, as you’ve seen on the picture, you might still use it. Sometimes, the counter ticks so fast even if there still enough toner to use inside of it.

Also, rotate the roller as the red arrow indicated.

Try to use it again by returning the cartridge back into your printer and the lever should turn the drum counter reset.

 

How to restart your printer remotely

first of all, you need to prepare a reboot file:

%-12345X@PJL COMMENT
@PJL DMINFO ASCIIHEX="040006020501010301040105"
%-12345X

Copy this to a notepad and save it as: reboot.txt (actually, you can named it anything you want...tehee!)

Now, to make a connection using CMD command to the printer.

On CMD, type the path where the reboot.txt is. Since i put mine at desktop, it will looked like this:

c:\user\unit01\cd desktop
c:\user\unit01\desktop

then, type ftp. It will be looked like this one:

c:\user\unit01\cd desktop
c:\user\unit01\desktop
c:\user\unit01\desktop\ftp
ftp>

type open 192.168.*.*, where this is the IP of your printer. afterwards, it will be looking for your password:

c:\user\unit01\desktop\ftp
ftp>open 192.168.*.*

hit enter if you didn't have any password, until the ftp> appeared again. and lastly type:

 ftp> put c:\user\unit01\desktop\reboot.txt

hit enter and wait for the ftp> to show again. notice the printer that it will restart by itself.

type the word "bye" to exit from the ftp mode.

...and that's how to restart the printer remotely.

I tested it to our office printer (HP Laserjet 4315dtn) and it works like magic.

How to get the IP of other computer using CMD

Sometime, you'll get a chance that you couldn't enter a specific computer using its computer name. And for that, you couldn't access the files you've need inside that computer. You could try using its IP, but how will you know its IP?

Try this steps:

1. Go to Run

2. Type ping -4 [computer name]

3. Hit the Enter button

And, it will show you a few pings of is IP number.


Easy isn't?

The Science Behind Rudolph’s shiny, Red Nose

Image from Google

     We all know that Rudolph and his legendary red nose are just too fictional. But have you ever wondered if a reindeer gets a red schnozzle in real life? Turns out, it really does.
     And there is a scientific data to prove this claim. According to the scientists from the Erasmus Medical Center in the Netherlands and the University of Rochester in New York, reindeer have 25% more capillaries in nasal membrane than us, humans. These blood vessels carry red and oxygen-rich blood towards the nose to keep them warm during a cold winter days. In addition to that, the capillaries also help them to regulate their internal body temperature because like other mammals, like dogs and cats, reindeer don’t sweat.
     Now, you know!
