Can Raspberry Pi boot from USB flash drive? And about how to do it guide.

Simple answer is 'yes, it can' but read on....
Or skip to the "So I will write summary first:" below.
Or skip to the "Raspberry Pi 3 B+ support USB boot.  How about Pi Zero W? Or other Pi?" below.

Not everyone is beginner, I think.

When people looking for how to guide for installing the OS(operating system), they were probably beginner or very first time trying to use Raspberry Pi. If that's the case, step by step guide might be very good choice.

But even so, it is better to explain general concept, I think.

If someone already knew some computer stuff, he or she probably doesn't need that step by step guide. Because Raspberry Pi is computer that means it is same concept.
For example, someone is Windows user like me and some Windows user knew if computer--motherboard support USB booting, Windows user can simply go to the CMOS setting and do boot from the USB stick.
So I'm thinking Raspberry Pi is computer so it might support USB boot, too.

So I'd like to know whether Raspberry Pi support USB boot or not. Or I might have to do something to get USB boot.
That's what I want to know, right?

So I will write summary first:

BCM2837-based Raspberry Pis which were all the Pi 3 models include compute module 3 and Pi 2 Model B v1.2, support USB host and Ethernet boot.

So if you have any of models with BCM2837, you can follow any general install OS guide (and install to the USB flash memory stick) which you might already knew.

And if you have other models include Pi Zero and Zero W, you need single file on your micro sd card and then it will boot from USB memory stick. So you can boot from USB memory stick and also need micro sd card with single file which I will explain below.

thought about boot from SD and then USB.

I am currently using the multiboot via berryboot.

And sometimes, I felt berryboot wasn't enough what I am trying to do. So I am thinking about like that.
3 or 4 OS on SD card and then 1 or 2 OS from USB flash memory.

So I was googling about it like this:
how do i install raspbian on usb memory

And I clicked below guide:

And read this part:
Important information
This tutorial is out-dated and has been updated here: ....
So I did clicked link which is below guide:

I have a Linux machine but most of my data--Raspberry Pi image file and etc, was on Windows which is my main computer.
So I clicked Windows version tutorial--below link.

I appreciate the detail guides. But when I am trying go through this guide it made me very confusing.
See this "Step 2 – Install Raspbian to the micro sd card"
And then "Note: If you’re using a Raspberry Pi 3+, you don’t need to do step 2. Jump straight to step 3."

"Step 3 – Install Raspbian to the USB Flash Drive"
The process is exactly the same as step 2, but this time we choose the USB flash drive as.....

And here--"If you're using a Raspberry Pi 3 Model B+, you can skip step 4."

"Step 4 – Prepare the Raspberry Pi for boot from USB"

"Step 5 – Boot Raspbian from USB Flash Drive"

I realised that it is exactly same step as install Raspbian on micro sd card.

I have Raspberry Pi 3 B+ and Pi Zero W. So I already knew how to installing any OS on micro sd card.

As you can see, it took very long time to figure out.
Unfortunately, I clicked very old guide--May 2013. That probably is the reason though.

Raspberry Pi 3 B+ support USB boot. How about Pi Zero W? Or other Pi?

I am thinking newer Pi can support boot from USB memory stick but how about Raspberry Pi Zero W which I also have.

So I googling about it and found this:

This question already reveal how to do the booting from USB stick.

Quoted from the question.
The older Raspberry Pi's (Pi 1, Pi 2 and Pi Zero) couldn't boot from a USB-device, but the Raspberry Pi 3 has support for it. The Pi and Pi 2 have semi-support for it (using an SD-card with a single bootfile).

So if I wanted to boot from USB stick in Pi 1 and 2, I can place single bootfile--which I don't know it yet.

And other people answered that Pi Zero W use older chip like Pi 1 and 2.

And then I found someone wrote about that single bootfile--bootcode.bin.
And pointed to the source:
Special bootcode.bin-only boot mode section in Raspberry Pi boot modes - raspberrypi/documentation
Quoted from above link:
USB host and Ethernet boot can be performed by BCM2837-based Raspberry Pis (these are all Pi 3 models, and some Pi 2Bs). In addition, all Raspberry Pi models can use a new bootcode.bin-only method to enable USB host and Ethernet booting.

Just format an SD card as FAT32 and copy on the latest bootcode.bin.

This is useful for the Raspberry Pi 1, 2, and Zero models, which are based on the BCM2835 and BCM2836 devices, and in situations where a Pi 3 fails to boot (the latest bootcode.bin includes additional bugfixes for the Pi 3, compared to the boot code burned into the BCM2837).

If you have a problem with a mass storage device still not working even with this bootcode.bin, then please add a new file 'timeout' to the SD card. This should extend the time it waits for the mass storage device to initialise to six seconds.

I'm not 100% for sure yet. But if Raspberry Pi use BCM2837, USB host and Ethernet boot will support.

And I found all the Raspberry Pi specifications from Raspberry Pi - Wikipedia.
Screenshot of Wikipedia's Raspberry Pi Specifications section.
And as you can see, Pi 2 Model B v1.2 uses BCM2837. And all the Pi 3--3 Model A+, 3 Model B, B+ and Compute Model 3, lite, 3+.

So if you have Pi 2 Model B with v1.2, Pi 3 series and Compute Model 3 series, you can just install any OS on USB stick and remove micro SD card.

If you have other version include Pi Zero W, you can format the micro SD card and copy the bootcode.bin file.

Yes, I haven't tried it yet. But I think those are from the Raspberry Pi's official repository.
So I'm sure it will work.

Kali and Raspbian booted from USB flash drive.

I probably have to get more information about it so I just found this:
quoted from above link:
HawaiianPi wrote:
The Pi3 will check for a boot SD card first, before booting from a USB device. If no boot SD card is found in 5 seconds, then it looks for a boot USB device.

I think this is quite similar process as USB boot in PC--desktop and laptop computer.

When I read from above link, someone said some USB disk won't work. And I wasn't sure about it--If it's FAT32, why it shouldn't be.

But first I tried with quite old 8GB USB stick, it didn't work--Pi 3 B+ without micro SD card and Pi Zero W with single file on micro SD card.
So I thought I need to do something.

And I realised this could be compatibility issue. So I put my kind of new memory card read which can read SDXC format card, too.


As you can see that micro sd card slot is empty.
Kali lite booted from USB Flash memory stick in Raspberry Pi 3 B+.
That USB memory stick doesn't work with USB boot--I tried like 2+ os and also with Pi Zero W.

This time, I tried same USB memory card reader with Pi Zero W. And it worked well.
And I had to put single file in micro sd card.
Raspbian stretch booted from USB Flash memory stick in Raspberry Pi Zero W.

If you'd like to connect more than two USB stick, portable hard disk or SSD, things became quite complicated. Because Raspberry Pi doesn't know which USB drive to boot from.

So you have to search more about it.

I hope you did learn about the basic concept or process of USB boot in Raspberry Pi.

Adafruit's Portable 5 inch Monitor with HDMI DIY looked interesting. But in reality....

I've seen this video: Portable HDMI Display for Raspberry Pi - YouTube

And I thought it looks very nice and quite useful because it isn't only for the Raspberry Pi--I can use as my DSLR monitor or game console monitor as well--I have a Nintendo NES classic edition which is kind of portable console.
So I'd like to do this....

It's expensive than I expected.

But when I saw inside of it, it shouldn't be easy to do.
Building the portable monitor won't be easy, for sure--I haven't done soldering before. But it requires a lot of parts to buy, too.

And if I do this, I might learn a lot of things about Adafruit, for sure.

So I visited building guide wep page.
Overview | Portable 5in Monitor with HDMI | Adafruit Learning System

And I realised I don't only spend a lot of time, I need a lot of money to building it, too.

  • 5.0" 800x480 TFT Display $29.95
  • TFP401 HDMI Breakout $24.95
  • FPC Extension Board $4.50
  • Powerboost 1000C $19.95
  • 2500mAh Battery $14.95
  • Slide Switch $0.95
  • Tripod Screw Insert $1.50
  • Total: $96.75

I thought this is too expensive for me. I need other things like print 3D case and lots of tools to do this.

So when I go through their guide, I saw that it can powering up the screen through USB.
That means, I can simply use my smartphone powerbank.
So no need to buy Powerboost 1000C and 2500mAh Battery.
And I don't have 3D printer so I don't need slide switch and tripod screw insert, too.

So I need three parts--5 inch display, TFP401 HDMI breakout, FPC extension board.
So total $59.4.

Cheaper or even better alternative--Aliexpress.

That means I don't need to do this.
Because I can simply buy from cheap Chinese store in Aliexpress, like this:
This is screenshot of 5 inch capacitive lcd display from Livetime Store in Aliexpress.
5 inch Raspberry Pi 3 Model B+ Touch Screen 800*480 Capacitive LCD Display + HDMI Cable + USB Cable + CD for Raspberry Pi 3-in Demo Board Accessories on

This is 5 inch capacitive touch display. And it costs $38--include free international shipping.
This model was different driver board design than 5 inch resistive display so I couldn't find case for this model.
5 inch resistive display case costs $6 to $10 in Aliexpress.
I can buy 5 inch display with case for about $48.

So it's much cheaper and better(include touch panel) than Adafruit's.
I know this because I just ordered one from there. So I search the a lot of similar--5 inch lcd.

If I wanted to learn about Adafruit, I probably can invest that much time and money.
But now I'd like to more focus on Raspberry Pi--and programming.

So I will buy 5 inch capacitive touch display.

You can also buy other 5 inch screen from Aliexpress like this:

This is the screenshot of '5 inch lcd hdmi' search result in Aliexpress.
Buy 5 inch lcd hdmi and get free shipping on

This is the screenshot of '5 inch screen' search result in Aliexpress.
Buy 5 inch display and get free shipping on

When you are searching the lcd screen, it doesn't show up many items. But you can find store that specialize in Raspberry Pi or SBC(single board computer). So you probably have to check Raspberry Pi store one by one.

It looks hard to build but maybe not that much.

At first, I don't think it's easy thing to do. When I saw this link:
On/Off Switch | Portable 5in Monitor with HDMI | Adafruit Learning System
It doesn't seem to easy, does it?
But if you are thinking about portable project, I think it's worth the effort.

I saw the next page. And if I learn about soldering, I think I can do this.
TFP401 Driver | Portable 5in Monitor with HDMI | Adafruit Learning System

And next,
Display | Portable 5in Monitor with HDMI | Adafruit Learning System
This part need just connect and position the cable. After that, screen is working.

Next part is mounting to the case.

Overall, if I learn and practicing soldering, it shouldn't be so hard.

But I still don't have a 3D printer and I don't like spend that much money.
So I will buy from Aliexpress.

Many of web store like adafruit, elements14, sparkfun, pimoroni were probably based on USA or UK so shipping and currency is too expensive to my country--Korea.
And same kind of store in Korea was all imported from those countries so things were much more expensive.

That's why Aliexpress is the best choice--for me. And probably to you, too.

How the sixty dollar console-Nintendo classic mini, costing an arm and a leg?

Summary – Sad story of a sixty dollar console costing an arm and a leg.
quoted from one of Amazon user's Nintendo NES Classic Edition Console review:

I also found similar one from customer Q&A sections @ #Amazon's Super NES Classic item page
Q: Will we ever have a chance to buy this?...
A: willing to pay but when you make it impossible to get except rip-off-bay it makes it meaningless that....

Simply put - Nintendo didn't make enough products and they just kept trying to shutdown the productions because they wanted sell their other main line product like Nintendo Switch.

Here is evidence of what I said was probably true:
Despite the positive reception, journalists were confused about Nintendo's decision to discontinue the unit as announced in April 2017. Nintendo did not say at launch that the system was meant to be only a limited run, and its...
quoted from Reception section of NES Classic Edition - Wikipedia

Their products are selling so well but they were simply stop producing the product. Does it make sense to you?

NES Classic Edition

Nintendo NES Classic immediately sold out

The NES Classic immediately sold out when it was first released in November 2016, with resellers charging hundreds of dollars for the popular product.
quoted from Nintendo's NES Classic and SNES Classic are going out of production - The Verge

more details from Scalping and bootlegs section of NES Classic Edition - Wikipedia
This, coupled with the extremely high demand, prompted internet scalpers to buy as many as they could, so they could resell them with extreme price markups. In the US, prices were commonly set between $200 and $500, compared to its launch price of $59.99.

answer--not physically destroy hdd, for erase data from a hard disk so no one can ever recover it.

Thinking about selling used hard drives.

Recently I bought external 2.5" hard disk drive because my external 2.5" hard drivers have low on free space. Copied all the data to new hard drive from old hard drives.
Now I have number of hard drivers--external 2.5" 500GB, 750GB and a few desktop PC 3.5" hard disks that no use. So I'm thinking about to sell it.

Before I'm selling, I needed to clean up the hard disk so no one can recover my personal data. I don't much have important data though--I have a lot of piece of writings and ideas. But I don't think people will understand what those a pieces of writing is for.
I know this because some of those ideas, I already wrote in my twitter or blogs but no one seems to understand what I am saying. So I don't much care about those.
But I have been learning photography so I have tons of photos which I'd like to erase it.

So I did googling and came across this--in Quora:
How do I erase data from a hard disk so no one can ever recover it? 

Why would you like to physically destroy hard disk which you spend a lot of money for?

Quite surprise to see so many answered with physically destroy the hard drive.

I thought -
Nowadays, everyone is sooo rich that everyone suggest to physically drilling, shredding the hard disk.
I'm not rich so I had to completely erase the data before selling.

I know the simple solution without physically destroying it.

I know how software works--because I was a programmer. So I know very easy and simple way. Download some software--bigger size will be better, useless documents or anything from the internet or your not important things like Netflix movie files. And delete all your data. And then copy the downloaded software, documents and all. And kept copy it(same files over and over--make folder to more easier--Windows will make new name for it like below screenshot) until hard disk became zero-ish byte of free space.
screenshot: overwrite files for make unrecoverable

So when the recovery software or professional try to store data from my hard drive, they will only recover those useless data.
It's THAT simple to permanently erase data.
Yes, it takes time. But it perfectly works.

Yes, someone answered what I suggested--overwrite data to remove personal data.
And someone saying that forensic analyse(or something) still can find a bit of information from there. Sure. That might be true.

That's why my solution makes more sense.

Because my personal data was already replaced by thousands, thousands and thousands of files.
That means forensic analyse take more, more and more time to figure out which bit of information connected to the which part of information. It's like thousands, thousands and thousands of jigsaw puzzles to figure out.
And it will be almost impossible because a lot of pieces were missing.

Loren Forslund answered very interesting one and I think it's very good method, too:
My method is using Ubuntu disks utility to break all partitions down and formatting the drive into one “FAT” partition. Now make 2 equal partitions and format them in EXT4 writing over the drive. Now break these partitions back to one NTFS partition over writing the disk. I’m sure if you had one million dollars worth of DOD equipment and 3 months of time you may get a scrap of something, but I doubt anything useful.

People watched way too much TV shows--CSI kind of TV shows.

Especially this part:
I'm sure if you had one million dollars worth of DOD equipment and 3 months of time you may get a scrap of something, but I doubt anything useful.
 - People were watched way too much TV shows
 - and they were way too much talk about this theoretical ideas.

Let's talk about reality.
I told you that I bought a external 2.5" hard disk which has 4TB space--actual size is 3.63TB.
So I put all my old data to this new hard disk..
screenshot: my external hard disk drive's files and folders

Last time, I had a lot of software and documents from the internet. But when I started taking photos, I had to delete those files because nowadays DSLR or mirrorless camera need bigger space to backup.
And other reason is I can always go online to get those software again.  So I don't need to kept in my hard drive.

So in my case, 50% of files(153,598 / 2 = 76,799 files) were probably personal data. But each photo was like 7 to 24 mega bytes only. I have software, downloaded documents, audiobook from Librivox and games and those were far more bigger size than photos.

So even if I have 50 to 70% of files were personal data(because photos I took), 40 to 80% of space were filled with not personal data. That means 40 to 80% of 0.98 tera byte.

That means if forensic analyse find a bit of information, it will quite likely not my personal data. For example, 70% of space were not personal data means:
other not important things - 1,003.52 giga byte * 70% = 702.464 giga byte
my personal data - 1,003.52 giga byte * 30% = 301.056 giga byte
Because my personal data was only 30% chance to picked up by forensic analyse.

And there has more. I have thousands of photos but do you think all of my photos were all very important photos--which I probably use it in my blog.
Photography is my hobby so technically it wasn't very important data.

Even if so, reality is this:
How many professional photographers really use all of their photos they took, do you think?

And how many people do you think they use their hard drive only for their important data?
Even if that's the case, why do they need 1 to 4 tera bytes of hard disk?

I have important documents but most of my documents(which I kept it in text file format--smaller than Word file format.) takes only a few kilo byte.
So I'm sure that a few giga bytes of hard disk should be enough for their personal--important data.

Reality of un-delete kind of software.

How I know this? Because about 10 or 15 years ago, I tried to recover my important data from un-delete kind of software with no success.
I can see the files with so many other files. But I can't recover it because it was already half destroyed--some new files already overwritten some part of those files.

You've known this, too. Good example is 'corrupted file'. Did you recover that corrupted file?

Reality is this:
Even if that forensic analyse find a bit of byte, what can you do with that part of byte?

It was 10 or 15 years ago experience so I have to check. And found this:
Recovering Deleted Files After Formatting: Is it Possible? | Deleted File RecoveryThere are many debates regarding the possibilities of recovering deleted files among computer scientists. All evidence points to the fact that in order to recover files deleted from recycle bin, or any other part of the operating system, they must not have been written over.

In order to recover a deleted file every sector that included data for that file must be in it’s original condition. Overwriting any part of this file with new data will cause corruption.

As you can see, this professional(??) data recovery company saying things were far different than what many people answered in Quora.
Professional data recovery company saying that they can't recover if it's already written over.
But many people in Quora saying that you can recover it--because you can find a piece of information with forensic analyse(or something). So you must do physically destroy hard drive--drilling, shredding, burning and among other physical way.

See the difference.

Even if you recover the part of file, you probably can't read--because of corrupted. But what many people in Quora saying is it can read--recover it.
* If you seen CSI kind of TV show, they can always recover it, don't they?
Yes, you can recover the random data. But do you think that random data is worth a million dollars with spent a few months or a year of work?

That's why I completely agree with what Loren Forslund said:
I'm sure if you had one million dollars worth of DOD equipment and 3 months of time you may get a scrap of something, but I doubt anything useful.

Reality is extremely different than what people were saying in internet, unfortunately.
This is how people kept getting more wrong ideas.

P.S. I found permanent file delete software:
They also explain same thing--overwrite to make unrecoverable.

No longer work on metered network to stop Windows 10 auto--force update!

Extremely forceful auto update in Windows 10 Home edition.

- Windows 10 Pro (and Enterprise) edition can easily block the auto update with group policy setting.

I was very irritated by Windows 10 update because it kept bugging me for restart.
So I had to find how to stop Windows 10's auto-update--I did this before about two years ago.

And I found two options:
One is set on metered network in wifi setting--turn on the "Set as metered connection".
Other one is change group policy settings. But this option is available for Windows 10 Pro and Enterprise edition. Mine is Windows 10 Home edition so I can't use this option.
* About two years ago, it wasn't possible to disable Windows 10 update service but now it might possible.

And luckily, I'm using wifi to connect internet so I did use first option.
You can see the screenshot for how I set the metered network:

screenshot - set the metered network in wifi setting

So I didn't get the update for quite while. About a month ago or a few months ago, I thought I needed update Windows Defender so I did use Windows update.

After that, at first I didn't notice much about this red circle with cross mark in Windows Defender Security Centre icon.
But about a month or two months ago, it kept showing the icon in taskbar like this:
screenshot - Windows Defender Security Centre icon

And then I just realise it that suddenly my mouse--actually, I'm using wacom tablet as mouse though, sometimes stuck--not responding like 5 to 30 seconds.
I thought this is because my computer--almost 10 years old laptop computer, was quite old so that is the reason that my mouse was not responding.

But it looks like actual reason is Windows 10 kept trying to update in metered network.
screenshot - auto update in metered network
It said:
Update settings
We'll automatically download and install updates, except on metered connections (where charges may apply). In that case, we'll automatically download only those updates required to keep Windows running smoothly.

So it will automatically download and updates in metered connections, too.

screenshot - awaiting restart in metered connections

I haven't try the disable windows update service yet. I have no other choice--I have to do that to stop auto update.

You can try some of things from here:

Stuck in a Windows 10 update loop - KB4088776

When I'm writing this, I realised that my problem is not only because of that reason. Those update numbers were very familiar--KB4088776.
It kept trying to install the update and then it kept failed like this:
screenshot - couldn't finish installing updates

I think I found solution for looping update of '2018-03 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4088776)' from here:

I'm not sure whether it will fix the problem but there have number of possible solutions so I think I might find a way.

P.S. Additional info. wrote at September 10, 2018:
My laptop computer's wifi network driver not working time to time, if I don't do the update for Windows 10--because metered network--partly blocked update.
Very strange happening--when it happened first time, I thought my laptop computer was too old because it's 8 to 10 years old. But it kept happening again. So I did update Windows 10 and it was okay. But three(or two?) month later it happened again. And just a few days--or a week ago, Windows 10 start showing warning of update. Very similar behaviour like first time.
Now I'm trying to update Windows 10 again. And I will write it again, whether wifi-issue was gone or not.

Additional info. wrote at September 14, 2018:
My guess was right. After update Windows 10, I am not getting wifi-network issues anymore.
So if I don't do Windows 10 update, I can't use internet.

Capitalism won't dominate this world.... Yet.

I haven't listen the audiobook for quite long time so I've visited LibriVox website--public domain books that people recorded.

And I found this book - The Mysteries of Paris - Volume 1 by Eugène SUE.

When I listen the chapter one, I was very and very intrigued by her lovely voice--Cori Samuel. And I found her website--To Posterity — and Beyond!.

I read a few things from there and I click the Voice services.

She said
At the moment, and for the foreseeable future, I am not accepting commercial recording requests.
Because she was so enjoy recording works for the public domain.

It's not everything is about money--commercialised.

People are so much focused on the making the money--That's how and why capitalism issue came from. Unfortunately, not many people see this side of the world--open source, public domain, wikipedia, creative commons, etc.
You can find so many websites or organisations doing those.

If you can see this side of world, you can see that we, human being's future is still bright.
We just need more people to involve and promote this open(and sharing) culture.

Warframe. It looks very promising....

Before go further, you should know that this isn't game review or anything. I found this game and I'm trying to figure out what kind of game it is so I can make decision for to play or not to play.
And I'm interesting to know about why so many people like the game.

Impressive game trailer and...

I just found out about Warframe and watched trailer:

and I was like 'wow'.

More surprising thing is this trailer was from 2013.

So I googled about it and found wiki article.
Warframe is a free-to-play cooperative third-person shooter video game developed by Digital Extremes for Microsoft Windows, PlayStation 4, and Xbox One.
quote from Wikipedia Warframe

Huh? Game trailer was really impressive graphics and story. And it was 'free-to-play' game?

I didn't get what 'third-person shooter' means, at the time. But I am not fan of first-person shooter game so this game probably wasn't for me.
So I just decide to know more about the game.

Interesting story behind the game.

So I read a few things more from that wiki article.
Warframe received mixed reviews by critics, holding the score of 68/100 on Metacritic, based on nine reviews.
The game is among one of the most-played games available on Steam.
More than 26 million players have played the game upon launch.
quote from Wikipedia Warframe - Reception section.

That's quite interesting so I did check the 26 million players part's original source.

What I like is this:
I will quote some part from The story of Warframe: how a game no publisher wanted found 26 million players @ July 15, 2016 by Tom Marks
Despite its large player base, Warframe's success remains low-key. A lot of people haven't even heard of the game nearly four years later, and Digital Extremes recognizes that.
For one, Digital Extremes doesn't do much large-scale marketing for the game
26 millions players are playing. But it still not many people even knew about the game. Because they didn't spend money for marketing.

For example, they held a panel at this year's PAX East but didn't actually have a booth on the floor like many of the game's competitors. "If we had a big booth, would that make it seem like we're more real?" Carter asked. "But that flies in the face of what Steve was talking about before, which is we're not going to spend money there, we're going to put everything we can into the game."

And I love very last part. 'they were going to put everything they can into the game'.
No wonder, game received very and very positive from user reviews.

screenshot - Warframe on Steam, user reviews
Above was screenshot of Warframe on Steam.
Overall: Very Positive - 91% of the 135,616 user reviews for this game are positive.
Recent: Very Positive - 88% of the 4,299 user reviews in the last 30 days are positive.

Not a fan of first-person shooter game. But maybe....

It looks good and user reviews also very positive.
Now I'd like to see what it's like playing in the game. So I googled it and found this.

I already told you that I am not a fan of shooter game and something I felt this game wasn't for me.

But after watching that--this is game's new open world game expansion, I might interest. Because adventure and exploring is my favourite game genre.

Oops. I just realised that I haven't check the game website--Warframe.
It's free. So you can easily try out yourself--available in PC-Windows, PS4 and Xbox.
If you decide to try it out, you can read quick start guide from Warframe website.

This is the reality---how Apple fanboy dominated this world. - Reality of web storage service.

I've got photos from friend--

screenshot from Best Of Quora facebook page

I didn't even read whole thing because I know the cost of web storage.

So I wrote in my facebook timeline:
This is the reality---how Apple fanboy dominated this world.
Do you know how much does it cost for 5giga byte storage for internet?
Do you know even give you free for about 200 times more size--1 tera byte of hard disk? Of course, they will display the advertisement but it was soo small that you will not even notice it.
Are you living in stone age that you think 5 giga byte of storage were some kind of miracle size?
Go and learn how internet became nowadays.

It wasn't really unlimited storage. And it wasn't started like that.

I was quite strange that Google give unlimited storage because there has limit. What I know is it will reduce the size, that's why I've got only 15 giga byte which isn't free at first, if I'm not mistaken.

Google advertised when you buy the android phone, you will get 15 giga byte of web storage.
I thought that 15 giga byte of web storage was really big about 3 to 5(??) years ago. But actually it wasn't.
Because I'm sharing with all of my google services like email, google docs, drives, photos, videos and even here--my blog service.

See. Actually it wasn't big. Because each product has 3 to 5 giga byte which is almost same as any other service.
For example, wordpress which is same as blogger here, give 3 giga byte of storage. You can read details here-Adding Storage Space — Support —
Other example, dropbox which is same as google drive, give 2 giga byte of storage. You can read details here-How much does Dropbox cost? - Dropbox Help - Dropbox
Onedrive which is same as google drive, give 5 giga byte of storage. You can read details here-Microsoft OneDrive Plans

People--even internet technology news writer, actually don't know why google give 15 giga byte. And they think google gave it for free because it was big.

Some of us know 15 giga byte was actually not big. So does Google.

Unlimited storage but compressed image--that means image quality will loss.

So Google offer the unlimited storage with limited photo size. I probably confused about this but if I'm not mistaken, they reduce the size more than half size if it was even 13 mega pixel. That's why I choose upload photos with original quality. I choose that almost year ago, I think.

Google Photos: Unlimited storage for free, with a few gotchas @ June 1, 2015 By Todd Ogasawara
Google Photo gives you unlimited storage space if you are willing to limit photo resolution to 16 megapixels and video resolution to 1080p. You do have the option to store at higher resolutions, but the storage counts against your Google Drive quota.

But it's not only photo resolution. It will compressed image, too.

Choose the upload size of your photos and videos - Google Photos Help
Photos are compressed to save space. If a photo is larger than 16MP, it will be resized to 16MP.

Or if you can buy a Google Pixel phone, you will get unlimited storage without those limitation. You can read here - Google is giving free, unlimited original-quality photo and video backups with the Pixel phones @ Oct 4, 2016 by Lauren Goode

Wait a sec. So Google only offer that much!?

Facebook, almost everyone using nowadays, right?
I've never seen any limitation of photos. People kept uploading it, don't they?
Yes, reduced photo quality(like Google does or more) and size but they gave almost(??) unlimited size, don't they?

How about Instagram?
Do I heard any limitation about photo uploading?
Yes, reduced photo quality(it wasn't much, I think. More for the size, I guess) and size. But they gave almost(??) unlimited storage, don't they?

How about which I mentioned very earlier.
Yes, they offer 1 tera byte of storage.

Do you think do I have to find out all the other websites about the offer? It's enough, right?

See the title of this article. "This is the reality--how Apple fanboy dominated this world."
That's why who has best answer. And choose that--Apple fanatic side of story, for the best of quora.

P.S. Slightly different but almost same story - Illogical idea ruled internet--especially social networking sites. @ March 17, 2017 - my other blog.

P.S. (at April 3, 2019): I found this question at - Why does Google offer unlimited storage for photos via Google Photos app? What's in it for Google?
So many answers include what I mentioned here.
Interesting thing is nobody talked about facebook or instagram. Because I'm sure they know about the websites and very likely using the websites. But they don't even know facebook and instagram gave unlimited photo storage like Google does--I'm sure some of their friends uploaded thousands and thousands of photos.

This is how human beings are thinking nowadays. -- to facebook timeline

If you know me, I always suggest to do the blogging. And I was totally right, after trying to find something from old post in facebook group. It was not just taking forever to load(extremely slow)--because mostly useless news articles, photos, etc.
There has zero creative or innovative thought in it.

This is how human beings are thinking nowadays. Don't care about old post. Just always looking for trend.

Everyday we trashed things to this rubbish timeline. And completely forgotten from your memory. And hopping for someone to understand my and your rubbish thought.

My facebook timeline probably also like trash but I'm trying to put some information--something useful, at least.

* I thought about write it in my timeline in facebook but I didn't. Not only because my friends will not understand.
Because I'd like to keep this thought in public so some people can see this.

Asphalt 8: Cost to win the Aston Martin One-77 Enduro Double Down, result and stats

I've won the Aston Martin One-77 three days before Enduro Double Down end. So I played it for five days.
screenshot of Asphalt 8 EDD - last tryout status at challenge 13

Here is my challenge list in Windows :
- After second EDD invitation challenge list, I included my collected points, spent tokens and car upgrade status. Fourth to eighth EDD tryout have some screenshots of challenge.

You don't have to read whole challenge list but first, second(or third) and sixth(and fifth)--which I collected more than 20,000 points should be enough.

Failed at ace race:
  • 1st tryout - challenge 23 Dragon Tree (I choose Auto-Pass), Challenge 29 Alps
  • 2nd tryout - Suddenly keys don't work middle of challenge 12 ace race, Oceanview Derby so I had to re-try. And I failed at challenge 17 London, about 0.3 second behind so I re-tried it. But failed it again.
  • 6th tryout - challenge 12 London
  • 7th tryout - challenge 7 Dragon Tree (I choose Auto-Pass)
  • 15th tryout - challenge 7 Dragon Tree

So 6 times failed on ace race.

Failed at not ace race:
  • 3rd tryout: challenge 20 Pagani Huayra, Gate Drift
  • 4th tryout: challenge 18 Pagani Huayra, Gate Drift (same challenge as above)
  • 5th tryout: challenge 18 Aston Martin One-77, Alps Reverse, Flawless (almost landed from last barrel roll but....)
  • 6th tryout: challenge 2 Bentley EXP10 Speed 6, The Great Wall with Beat time of 1:11:000
    • I know that I shouldn't try this 'Beat a time' challenge but I have triple booster so I thought I can make it.
    • That's why so many people suggest not to play this 'Beat time' race unless have fully upgraded car.
  • 7th tryout: challenge 13 Bentley EXP10 Speed 6, Tokyo Reverse, Beat time
  • 8th tryout: challenge 13 Bentley EXP10 Speed 6, Tokyo Reverse, Beat time (same as above)
    • I'd like to try it. But not a chance. Not only because of rank. Quite huge traffics on the road--also quite different traffics.
  • 9th tryout: challenge 27 Lucra L148, Barcelona Reverse, Unplugged, Finish first
    • I don't remember how did I fail this one. My Lucra L148 is fully upgraded it so I'm pretty sure that I can easily finish first. Probably two or three times crash to the wall or something.
  • 10th tryout: challenge 22 Peugeot Onyx, Sector 8, Beat time 1:08:000
    • I know I shouldn't try 'Beat a time' challenge but not much choice so I tried it.
  • 11th tryout: challenge 24 Bentley EXP10 Speed 6, Rapio Park, Beat time
    • Beat the time challenge is hard but why I chose it? It was a misclick.
    • See that's why I can't go double at 12 and 17. Low upgraded cars--Bentley, Onyx, were kept pop out in my challenge.
  • 12th tryout: Challenge 16 Peugeot Onyx, Temple Drive
    • Maybe possible with booster but I failed challenge, anyway.
  • 13th tryout: Challenge 15 Bentley EXP10 Speed 6, Dubai
    • I crashed at the beginning--probably because of traffics. And when I try to enter the shortcut which is big curve, other AI hit me. So I crashed again to the wall. And then I couldn't take the shortcut route. So I failed it.
  • 14th tryout: Challenge 14 Pagani Huayra, The Mirage, Infected with traffics.
    • Traffics on the road. So I crashed. And then I couldn't pick up the bottle or crash other AI car so I couldn't made it to the finish line.
  • 16th tryout: Challenge 18 Aston Martin V12 Vantage, Iceland, Beat time
    • I didn't really try it. So I failed.

So 13 times failed on not ace race.

* When I played in Webster Faster One EDD, I felt that ace race wasn't really big deal--if I upgraded enough.
Many times I failed other challenges. Here my stats show same thing. 6 times failed only on ace race. Other challenges are more problematic. That means I must upgrade a lot even if I don't own the car.

EDD wasn't easier than what people are saying.

I remembered the Weber Faster One EDD that it was really difficult but many people are saying that it wasn't that hard. As you can see, it wasn't hard if you upgrade all the necessary cars to max out or more. And use booster a lot.

But as you can see below, it was quite expensive to upgrade. It was okay to upgrade Aston Martin One-77. But problem is Bentley EXP10 Speed 6 and Peugeot Onyx which I don't own. And I probably never afford to buy Peugeot Onyx which costs 6,400 tokens.
You can't afford to buy the car but you have to upgrade it(it's expensive to upgrade) for win.
That's quite crazy, don't you think?

Anyway, in Android, I couldn't get the Nissan Skyline GT-R (R34) which required 40,000 points. I probably collected like 23,000+ points.
Of course, I failed badly, that's how I learned. I've won Webster Faster One in Windows.

That's why I knew after collecting 20,000+ points, it will become difficult.

Quote from 6th tryout:
Trying to calculate the safe collecting point for win the car.
I didn't upgrade it because I can collect enough points.
My point is 25,305. So I need 35,000 points to make 60,000 points.
It still remained 6 days. And 3 EDD invitations per day. So 18 EDD invitations to collect 35,000 points.
So if I can get about 1,945 points per EDD invitations, I can win the car.

But actually, next tryout, I did upgrade the car. Because I realised that it will be very hard to beat challenge 12--which will give around 2,610 points with car rank 1618 (max 2322, pro 3253).
Until challenge 7, I will get 1,160 points only. So it wasn't enough for 1,945 points.
So I needed to do until challenge 12. So with 1618 rank, I must use triple booster--that means very expensive because Extra Tank costs 200 tokens.

After 20,000 points, it will become difficult than before. But that's not all.
Challenge 3 Oceanview Derby was my first tryout's challenge 17.
And then it became challenge 12 in second, third, fourth, fifth tryout.
Challenge 7 Dragon Tree was my first tryout's challenge 23.
Challenge 12 London was my second, third, fourth and fifth tryout's challenge 17.
This ace race challenge will stay same until the end.
But what you have to remember is that other not ace race challenge will slightly become difficult. It will not become very hard. But it will.
For example, I saw traffics(other AI cars) on the road at first tryout's challenge 19. But later I've seen traffics on challenge 16 and more later, challenge 13.
So you have to upgrade it slightly more for prepare the difficulty changes.

Quote from 7th tryout:
My strategy for the upgrades
Previous--sixth tryout became difficult because I collected more than 20,000 points. So now I know what to expect. Because this ace race difficulty will stay same. So now I can decide whether how much more upgrade to defeat the ace race.

I know I can win the car. That means I will upgrade it, eventually. So it is better to upgrade now so I can save boosters.
Double booster--Nitro Starter and Tuning Kit isn't expensive but if I kept using it, it will be expensive.
Until this tryout, I probably spend more than 10 that means 175,000 credits. So it is better upgrade more.

Extra Tank is slight different reason, quoted from second tryout:
Previous Weber Faster One EDD, I made mistake almost every time. That made me quite crazy--I probably spend more than 1,300 tokens--problem is I failed on easy task many times.
So this time, I was on Extra Tank almost all the time until yesterday's one--12th EDD invitation.

Collected points (spent tokens):
  • 1st - collected 8,300 points (Auto-Pass so spent 500 tokens)
  • 2nd - collected 2,630 points (Two times of Re-try so spent 400 tokens)
  • 3rd - collected 3,695 points
  • 4th - collected 4,760 points
  • 5th - collected 4,760 points
  • 6th - collected 1,160 points
  • 7th - collected 2,630 points (Auto-Pass so spent 250 tokens)
  • 8th - collected 2,630 points
  • 9th - collected 5,465 points (Re-roll for three times so spent 75 tokens)
  • 10th - collected 3,695 points
  • 11th - collected 5,465 points
  • 12th - collected 2,630 points
  • 13th - collected 2,630 points
  • 14th - collected 2,630 points
  • 15th - collected 0 point
  • 16th - collected 3,695 points
  • 17th - collected 3,695 points

Spent tokens:
  • First and Second tryout, I spent 900 tokens.
  • Sixth tryout, I failed at challenge 2. So I spent 40 tokens.
  • Seventh tryout, I failed at challenge 7 Dragon Tree ace race so spend 250 tokens for auto-pass. You can read details here - Asphalt 8 EDD(Enduro Double Down), It's harder than what people are saying.
  • Ninth tryout, I spent 25 tokens three times(so 75 tokens) for re-roll.
  • Total: 1,265 tokens.

Car upgrade status:
  • Aston Martin One-77 upgrade status: R1646 (max 2322, pro 5255)
  • fully maxed and proed it--Aston Martin V12 Vantage, Lucra L148, Pagani Huayra
  • After collecting around 20,000 points, I don't get any more challenge from these fully upgraded cars: AC 378 GT Z, Aston Martin DB9 Coupé, Aston Martin V12 Zagato
  • Bentley EXP10 Speed 6 upgrade status: R1544 (max 1211, pro 2222)
  • Peugeot Onyx: R1563 (max 2322, pro 1111)

Spent credits and pro cards for upgrade:

Aston Martin One-77 upgrade R1646 (max 2322, pro 5255):
I have only one Free A Class Upgrade from mastery rewards. So I probably saved 250,000 credits.
790,000 credits for upgrade but I spent one free upgrade worth 250,000 credits.
So 540,000 credits.

pro upgrade:
Tires - A x14
Initial Tech x2
V12 Engine x3
Mid-Tech x3
Advanced Tech x2
363,550 credits

Suspension - A x3
Early Tech x2
69,600 credits

Drivetrain - A x14
Initial Tech x2
V12 Engine x3
Mid-Tech x3
Advanced Tech x2
363,550 credits

Exhaust - A x14
Early Tech x2
V12 Engine x3
Mid-Tech x3
Advanced Tech x2
333,350 credits

pro upgrade total:
1,130,050 credits

Tires - A x14
Suspension - A x3
Drivetrain - A x14
Exhaust - A x14

Early Tech x4
Initial Tech x4
Mid-Tech x9
Advanced Tech x6

V12 Engine x9

540,000 upgrade credits + 1,130,050 pro upgrade credits = 1,670,050 credits

* I will have the car so it's not a big deal.

Bentley EXP10 Speed 6 upgrade R1544 (max 1211, pro 2222):
168,800 credits for upgrade

pro upgrade:
Tires - A x3
Suspension - A x3
Drivetrain - A x3
Exhaust - A x3

Early Tech x4
Initial Tech x4

267,025 credits for pro upgrade

So total 435,825 credits.

* I have quite enough Class A cards so I upgraded it pro instead of max upgrade.

Peugeot Onyx upgrade R1563 (max 2322, pro 1111):
179,700 credits for upgrade

pro upgrade:
Tires - S x2
Suspension - S x2
Drivetrain - S x2
Exhaust - S x2
Hybrid Engine x4

54,650 credits for pro upgrade

So total 234,350 credits.

* I have quite enough Class S cards and Hybrid engine card so I upgraded it pro instead of max upgrade.

Bentley EXP10 Speed 6: 435,825 credits
Peugeot Onyx: 234,350 credits
With pro cards.

So 670,175 credits were wasted.

* This is one of the thing that many people don't talk about. If you understand this, R&D and EDD are very difficult and very expensive than what people are saying.

Spent boosters for lower rank of car or play it safe:

Here is the reason why I use boosters:
Previous Weber Faster One EDD, I made a mistake almost every time. So that made me quite crazy--I probably spend more than 1,300 tokens--problem is I failed on easy task many times.
So this time, I was on Extra Tank almost all the time until 12th tryout.
I started to use ace race challenge 7 with triple booster-Nitro Starter+Tuning Kit+Extra Tank. Actually this triple booster is for ace race.
So even if I made a mistake, I probably can catch up the AI.
Other reason is I didn't upgrade enough yet for compete with AI.

* Nowadays, If you don't use booster in EDD or R&D or even TLE(Time-Limited Event), things are really going bad. Because AI cars are very aggressive. They will play suicide with your car. Or barricade road. Or hit the traffics and than make trapped with those corpse of traffics.
If I make a little mistake on the road and then near the finish line--very good example is Iceland, AI suddenly catch up my car and go play suicide or make a trouble so made me failed main goal.
It became more and more necessary items than before.

This is how I use booster:

Many times, I don't even use any booster for TLE(Time-Limited Event). I will use only if I can get better reward because without booster, I can still make within 5,000 in recent daily heat TLE.

For example, yesterday's The Monday Heat TLE:
Screenshot of Asphlat 8 TLE The Monday Heat result

Screenshot of Asphlat 8 TLE The Monday Heat result with position

As you can see, I didn't use any booster. And made to 1,895 position. So if I use double booster (I don't think it's easy because it was very competitive to make top 1,000 or 500--many times without triple booster is very hard because I don't really have best TLE car like Mitubishi Eclipse, (have a Toyota Supra RZ but don't have i6 engine card to pro. But at least I have a Felino cB7.), McLaren 675LT, Mosler GT3, Bentley EXP10 Speed 6 or Chevrolet 2016 Camaro SS. S class, my best cars are W Motors Lykan HyperSport and Weber Faster One.
In Android, I have Koenigsegg One:1 and Peugeot Onyx but it was almost useless in any TLE and even in MP(Multiplayer).

If I use double booster--Nitro Starter+Tuning Kit, maybe I will get a Nitro Starter. But just one. So should I pay 17,500 credits to get 7,500 credits more? Of course not.
And make within 1,000 position is very competitive so if I can't make it in 5 times (2 fuel to require to play), I had to pay 17,500 credits more for try again. So it's actually expensive.

But if case like this, I will use booster:

Screenshot of Asphlat 8 TLE The Tuseday Heat

Screenshot of Asphlat 8 TLE The Tuseday Heat result with position
If I can make less than 1:28:000, I can get 25 tokens. And I tried it without booster. But I can make it like 1:29:xxx.
I tried with Nitro Starter but it still isn't enough.
So later I will use Tuning Kit only because it's long track so I probably can make 2 seconds faster than without booster which is enough to get 25 tokens.

Of course, I can use Tuning Kit with other TLE like Mercedes-Benz GLC Coupe Cup or Cadillac ATS-V Coupe Cup. Only 10 fuel so I can't try more than two TLE.

So as you can see, I can play quite well even without booster.

I didn't actually write down how many boosters I use. But luckily, I recorded some of EDD ace race. So this is almost beginning one--first try out's challenge 7, Highland View.

screenshot of Asphalt 8 EDD - my status of booster at the beginning

I have 41 of Nitro Starter, 29 of Tuning Kit and 56 of Extra Tank.

I use the Extra Tank for safety measure but this helped a lot in any challenge.

screenshot of Asphalt 8 EDD in 4 days--status 13th tryout before challenge 12
So this screenshot was in 4 days of EDD which is my 13th tryout before the challenge 12.

screenshot of Asphalt 8 EDD in 4 days - my status of booster

I have 15 of Nitro Starter, 12 of Tuning Kit and 52 of Extra Tank.

So I spent
  • Nitro Starter x26  worth 195,000 credits
  • Tuning Kit x17  worth 170,000 credits
  • Extra Tank x4  worth 800 tokens
  • Total: 365,000 credits and 800 tokens

How this booster helped in EDD:

I have collected booster from TLE and mastery rewards so I actually didn't spend credits. But I can't get that much easily again.
Last Webster Faster One EDD, I've failed (only 23,000+  points) in Android and I've win in Windows. And in Windows, I've win just before one day and a few hours (or two days) before EDD end.

This time, I've win before three days. So it saved almost two (or one day and 10+ hours) days.

If you play two or three invitation in one go, it will take more than one or two hours.

I will give you more evidence:
I played same EDD in Android later. And I have one more car--Peugeot Onyx than Windows. So I need upgrade for Bentley EXP10 Speed 6 only. And I upgraded Aston Martin One-77 to R1709 (max 2521 pro 5555)--compare to R1646 (max 2322, pro 5255). And upgraded it very earlier than Windows's.
And I already knew what kind of challenge will pop out--it wasn't much different than Windows.
But I've finished only 16th tryout so just one before--17th tryout Windows's EDD.
I upgraded a lot so I didn't much use the booster.

So if I didn't use booster, I must upgrade Aston Martin One-77 a lot and have to more longer days to win the car.
See booster can make a lot of difference.

How much credits, tokens and pro cards were wasted for win the Aston Martin One-77.

I will not include Aston Martin One-77 because I won the car. So all the upgrades and pro upgrades, I will have it.

1,265 tokens for failed challenge.
365,000 credits and 800 tokens for booster.
670,175 credits for upgrades - Bentley EXP10 Speed 6, Peugeot Onyx

1,035,175 credits and 2,065 tokens.

and pro cards:
Tires - A x3
Suspension - A x3
Drivetrain - A x3
Exhaust - A x3

Tires - S x2
Suspension - S x2
Drivetrain - S x2
Exhaust - S x2

Early Tech x4
Initial Tech x4

Hybrid Engine x4

These were just wasted. Those were kind of minimal requirement.

But don't forget. If you don't use booster, you probably need more upgrade for all the cars. I didn't upgrade much for Bentley and Onyx because of booster.

Bentley and Onyx's remain upgrade is quite close to 100,000+ credits so it is still better to use booster. Because remain booster can be use other challenge--especially ace race.

It's possible without booster. But you probably have to max out the all the cars. That means
  • 3 million credits for max out the Bentley
  • 1.15 million credits for max out the Peugeot Onyx
  • 1.53 million credits to max out the Lucra L148
  • 1 million credits to max out the AC 378 GT Z

So if you don't have cars, you have to wasted 6.6 million credits.

Of course, you can upgrade like 4424-ish so save some credits. But it still need a few million credits.

EDD rewards:
Yes, there has EDD rewards but this wasn't even enough for upgrade Aston Martin One-77. So I didn't mention it.

--- I haven't write it yet.

I tried this EDD in Android again because I have all the cars fully upgraded it except Bentley. And I don't have high-end A class car, too.
* It wasn't very different from Windows. Probably because I have very similar cars for this EDD--only difference is Peugeot Onyx.

This is why Wikidpad has so much potential in it.

WikidPad - wiki notebook for Windows/Linux/Mac OS

wikidPad is a Wiki-like notebook for storing your thoughts, ideas, todo lists, contacts, or anything else you can think of to write down.

What makes wikidPad different from other notepad applications is the ease with which you can cross-link your information. Links in a wiki are created by typing in WikiWords.

Donationcoder forum's user CWuestefeld explained about Wikidpad @ January 31, 2008

I would suggest to read from the link.

These are the quotes from CWuestefeld:
"... its parent. But a wiki allows any node (page) that relates to another to offer a link to it, leading eventually to a very densely packed structure."

"if you're consistent about the way you name things in a wiki, you'll find that the interconnectedness arises all on its own. You don't need to intentionally create a link; the link manifests itself based on the usage of similar terms."

"It's very gratifying when working in a wiki to discover that you've already done something that you forgot about. As you're describing a related concept leading up to another page, you find that the link is already populated; simply by thinking descriptively and consistently, you've created a knowledge web that not only holds together, but reinforces itself."

When I read about it, I also understand why wikipedia made whole different internet-era.

It's an idea that matters most. Isn't it?

You are glad to limit your imagination!?

You shouldn't limit your imagination. But you are happy to limit your imagination to 3.5 to 10 inch iPhone, smartphone or tabletPC screen.

Wednesday, May 28, 2014 will shutdown.

This is what I wrote to my twitter account.

#Springpad Interesting idea and it could better. But painful to use & horribly slow. Managing the text is that hard?!

If you'd like to know what I mean, you can simply install #Ted text editor in #playstore. And then run it. & run the #Springpad. compare it.

They had some interesting ideas and it went well.

But they took same mistake path like poor performance in fundamentally important thing. However you try to change, is basically text editor. So if it lose competency in fundamental thing, people won't try to use it much.

It means company will lose their customers.

Get out of your narrow-minded world.

Unfortunate happen in human society…farewell to the

Unfortunate happen in human society. So I should say #farewell to the #isoHunt. (this link is wikipedia article of isoHunt) #p2pSearchEngine #BitTorrent

Why? Because Knowledge became more powerful than ever in digital age which develop more and more society divided issues. #moneymakesmoney

These lawsuit will bring down these things and poor people will never get chance to improve themselves. Who cares about poor people, right?

This is the reason internet is the future and it will bring equality to human society.

Public domain, open source project, creative commons, etc. These kind of things I will talk about here, too.

That's what I believe.

This is how I learn things from internet.

I was quite curious about what timezone would apply in North and South Pole. So I found these two article:

And then I found interesting youtube video which is webcam from North Pole.
North Pole Web Cam 2011 – YouTube by NOAAPMEL

I've seen youtube video and then I thought ‘What this is for?' so I've searched more about it. Actually, you can read about purpose of put it in the youtube from that video.

This is homepage for that youtube video: NOAA Arctic Theme Page – A Comprehensive Arctic Resource

And I didn't read whole part but I found quite interesting and informative article: What has been happening to polar bears in recent decades? by Scott L. Schliebe

Do you think you can find this information without internet? Maybe.
But I am Korean and I am sure that I can't find this kind of information about 20 or 30 years ago when there hasn't internet. Because very less (or none) Koreans went to North Pole. So how can I find (and contact with) these Koreans. So it's almost impossible.

This is one of reason that I believe internet will change humans and human society for good.

ps. I've forgotten to mention about beginning of this curiosity. When I googled with 'what time is it in North Pole and South Pole' and then I found a bit weird answer. That's how I start.
