pip error main(?)

I just upgrade my pip in raspdebian and I got this error when I run pip

Error message

Traceback (most recent call last):
  File "/usr/bin/pip3", line 9, in
    from pip import main
ImportError: cannot import name 'main'

I already tried to reinstall pip from apt but it didn't solve the problem

In the end, I found something

type in terminal

nano  /usr/bin/pip

that will open pip file like this

import sys
from pip import main
if __name__ == '__main__':
     sys.exit(main())

1. Change "from pip import main" to "from pip import __main__"
2. Change "sys.exit(main())" to "sys.exit(__main__._main())"

The result is like this

import sys
from pip import __main__
if __name__ == '__main__':
     sys.exit(__main__._main())

exit nano and save

and you can use your pip again

Change phpmyadmin's URL in ubuntu

A few years ago I put some note for windows here

and now I will make one for ubuntu

So for example, I want to change my phpmyadmin link

default: 127.0.0.1/phpmyadmin and I want to change it to 127.0.0.1/myownlink

we need to change 1 setting in apache2

sudo nano /etc/apache2/conf-enabled/phpmyadmin.conf

change the alias

Alias /phpmyadmin /usr/share/phpmyadmin

to

 Alias /myownlink /usr/share/phpmyadmin

then we need to activate and restart apache2 (maybe only restart apache2 will do it)

 sudo a2enconf phpmyadmin.conf

 sudo systemctl reload apache2.service

done yey \o/ 

MySQL in ubuntu 18.04 (update)

1.1. mysql secure installation (optional but recommended)

sudo mysql_secure_installation

2. Installing apache2

sudo apt-get install apache2

3. Installing phpmyadmin

sudo apt-get install phpmyadmin

4. connect apache2 and phpmyadmin

sudo ln -s /etc/phpmyadmin/apache.conf /etc/apache2/conf-available/phpmyadmin.conf

Arduino nano suddenly get error: avrdude: stk500_getsync() (Solved)

I am still new in arduino things
I use the arduino IDE from windows store with auto update on.

So basically what happen is like this:
My PC using Arduino IDE v1.8.5 because I never close that window so it never update.
And then when I try to upload a program from my laptop which is use Arduino IDE v1.8.7, I got these error

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x53
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x65
avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x74
avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x75
avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x70
avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x50
avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x44
avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x0d
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x0a
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x72
An error occurred while uploading the sketch

After doing some googling (thanks Mr. google), I found out that this error means that you computer has connection problem with your arduino, meanwhile I didn't do anything since the last time.

The same error happened after I update my IDE in my PC from v1.8.5 to v1.8.7

Finally, I found out that I used the wrong processor
So basically there are update in bootloader of nano and I need to use the ATmega328(Old Bootloader) instead of ATmega328

And that fix all my connection problem
I hope this can help, for someone who still use the old nano bootloader

Install Jupyter in windows 10

As my previous diary is about jupyter here

so now I will make a note how to install jupyter in windows 10 (my current OS)
I assume you already have anaconda installed

To install jupyter we need to do this step

python  -m pip install jupyter

I think it will be the same in linux, but I haven't try it yet

pip install jupyter

And done


Then after that you can run it by type

jupyter notebook

on you command prompt

It will open http://localhost:8888/ in your browser

Jupyter python

So I started to use python 1 year ago,
usually I just write the code in notepad++ (really?)
yeah it is notepad++
not because I don't need any IDE, but just because I am too lazy to install it
and notepad++ is enough for me (I just need the colors things - for now)

Then I saw some of my friend use jupyter, so I will try to use it
why?
because I curious about ipython, i from internet maybe, I am not sure
but maybe it will be fun

It is for debugging perline/cell and make a beautiful doc in your doc

I already put how to install jupyter in windows 10 here

Apache can't restart

When I restart apache, I get this message:

apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

The solution is

• sudo nano /etc/apache2/httpd.conf or apache2.conf
• Add: ServerName localhost
• And restart apache: sudo /etc/init.d/apache2 restart

First I've install Windows 7 in my laptop and now I want to add Ubuntu 13.10 (Saucy Salamander).
And this is my first time to install dual boot ubuntu.

This is the step of installation:

1. From windows 7 you need to prepare (and format) the primary partition for ubuntu partition (I using EaseUS Partition. You can download it from here). Ubuntu using ext2 format. Note: ubuntu only allow 4 primary partition so change all your data partition as logical partition
2. After that you can install your ubuntu via DVD or flashdisk (I using DVD). You can read the installation step here. For step 4 using try something else and choose your partition that you have prepared in number 1.
3. And now you have Windows and ubuntu in your computer.

The World God Only Knows III v0.1

Actually I rather disappointed because they didn't make some conquers
I want to see how Keima conquer Yui

As its title it will start with Goddess Arc

And also this is the third anime that make us don't understand all of the story if we don't read the manga
(another is Hayate season 3 and Rozen Maiden season 3)
And coincidentally this is also season 3 of TWGOK

Hmm...
Also I like the first season opening than this
because it seems the opening is not TWGOK opening
(just my thought)

To Aru Kagaku no Railgun S v0.1

Just watch to aru kagaku no railgun S episode 13

yeah maybe episode 15 is Touma vs Accelerator
and next episode (episode 14) is going to be epic ending like before

And it seems the code of the project is still the same
although they postpone it once

Also I just know that there is two sister there and Touma has meet them before

To be honest I like this point of view (from science) than To Aru Majutsu no Index
Maybe because I like science
lol

Rozen Maiden 2013 v0.1

I just watching (or skimming) the rozen maiden 2013 episode 1

And it summary all the chapter from the Rozen Maiden's manga

For someone who don't read it maybe don't really understand
because it is different from the previous two season
(actually the first and second season is not have the same plot with the manga)

It seems this season will be focus on Rozen Maiden II's plot
(you can hear that they say seven Rozen Maiden and not six and you can see who is the seventh Rozen Maiden)
So maybe it will be a good story
(I've read it but I feel so sorry for Hina Ichigo -> one of my favorite doll)

But actually I like the first and second season's art than this
I don't know is it because I just still don't familiar with it or not

And I also just realize that Suigintou's voice actor is Rie Tanaka
(same with Maria in Hayate no Gotoku and Lacus Clyne in Gundam Seed)
link: http://en.wikipedia.org/wiki/Rie_Tanaka

Promise

Because I don't know what will I post in this blog

then one of my friend tell me that he will go to comiket genco

wow it is very awesome and cool for me

althought maybe you can't tell that I am an otaku

then I'll post this

Now in 8th August 2012

I promise someday I will go to Japan

and go buy some otaku's stuff

Punctuation is powerful!

An English professor wrote the
words, "Woman without her man
is nothing" on the blackboard and
directed his students to punctuate
it correctly. The men wrote:
"Woman, without her man, is
nothing." The women wrote:
"Woman: Without her, man is
nothing."
Punctuation is powerful!
