#Metoo

The movement me too wast started by Tarana Burke. She started the nonprofit organization that helps victims of sexual harassment and assault. 

The actress Alyssa Milano gave the hashtag #metoo a new impulse. Ms. #metoo was seeking to give a voice to sexual abuse victims, after accusations of sexual harassment and assault were leveled against the Hollywood producer Harvey Weinstein.

Time's up  letter in the NYtimes 1-1-2018

Time's up movement is started with a letter in the new york times. https://www.nytimes.com/interactive/2018/01/01/arts/02women-letter.html. The letter is signed by 

“The struggle for women to break in, to rise up the ranks and to simply be heard and acknowledged in male-dominated workplaces must end; time’s up on this impenetrable monopoly,”

Time’s Up members include the actresses Ashley Judd, Eva Longoria, America Ferrera, Natalie Portman, Rashida Jones, Emma Stone, Kerry Washington and Reese Witherspoon; the showrunner Jill Soloway; Donna Langley, chairwoman of Universal Pictures; the lawyers Nina L. Shaw and Tina Tchen, who served as Michelle Obama’s chief of staff; Maria Eitel, an expert in corporate responsibility who is co-chairwoman of the Nike Foundation and Shonda Rhimes, the executive producer of the television series “Grey’s Anatomy,” “Scandal” and “How to Get Away With Murder”

The dress code was black as a  symbol to show solidarity with victims of sexual harassment inorder to to times up movement. It’s a message. It’s a way of expressing your support for this movement and the fact that it’s time to support one another.” 

Ophra  was  accepting the Cecil B. DeMille lifetime achievement award and made a speech  “I want all the girls watching here now to know that a new day is on the horizon!". The speech was 

Barbra Streisand  telling the room that she was dismayed that she was still the only woman to win the directing category, saying, “Folks, time’s up,” before naming the winner of Best Motion Picture – Drama

  Network problems 

1 Check that the hardware is connected (lights on both ends) or with iwconfig wlan0 (for WiFi)
2. Check that the kernel can see the hardware with:
ifconfig -a
3. Check that you active interface has an IP address 
ifconfig eth0 
ifconfig wlan0

4. Check the kernel routing table 
route -n (or ip route)

sudo route add default gw 192.168.2.1 wlan0

5. Check you can ping your gateway (you get the gateway address from the route command)
ping 192.168.2.1
6. Check you can ping 8.8.8.8 (Google's DNS server)
ping 8.8.8.8
7. Check you can resolve host names (ping google.com)

Sound picture: An audio analysis of the song If i Loved You Barbra Streisand


Formants are strong frequency peaks (transients)

The work on my audio skils i used this song. 

lyrics 
written bij Oskar hammerstein

If I loved you,

Time and again I would try to say

All I'd want you to know.

If I loved you,

Words wouldn't come in an easy way

Round in circles I'd go!

Longin' to tell you,

But afraid and shy,

I'd let my golden chances pass me by!

Soon you'd leave me,

Off you would go in the mist of day,

Never, never to know how I loved you

If I loved you.

The song is a small story. As barbra describes if  her self the song must have a beginning and an end.

Now why is this so beautiful phrased?

Pitch is the fundamental frequency (steady)
The pitch goes from 3768 slightly up to 393

1 problems

I flashed code into my micro:bit via Bluetooth and it no longer works.

2 Can my phone /tablet pair with the micro:bit?

Since the BBC micro:bit employs the low energy version of Bluetooth wireless communication, the iPhone or iPad running the app must have Bluetooth low energy capability. Unfortunately this excludes some older models. Basicly all new android phones/tablet and apple device will work.

3 Normal pairing how does it work?

The method of pairing requires holding down buttons A and B and pressing and releasing the RESET button. Normally, A and B need to be held until the message “PAIRING MODE..” begins to scroll across the LEDs. The requirement of entering a pattern and 6-digit code ensures security in an environment where there may be several micro:bits.

4 re-instate Bluetooth after previously using MicroPython

5

A compiled HEX file contains not only your script code but also ‘runtime’ and ‘bootloader’ code. Bluetooth communication depends upon the runtime and bootloader code in micro:bit. If the runtime or bootloader code in micro:bit is corrupted or overwritten with incompatible code, Bluetooth flashing and pairing will fail, and the only method of restoring it is to flash a suitable HEX file from a computer via a USB cable. Touch Develop and the Block Editor compile suitable HEX files. Currently, HEX files compiled from python scripts are not compatible with Bluetooth. From time to time the runtime and bootloader code from the website is updated, so it is good practice to create fresh HEX files by re-compiling your scripts.

6 What if I do not want to pair?

Bluetooth pairing takes time. n your project folder's root, you should have a file called config.json. All you need to do is ensure there's a property of the bluetooth json object called 'open' which has a value of 1. open=1 means 'no security'. Here's the first part of my config.json file:

{
    "microbit-dal": {
        "bluetooth": {
            "enabled": 1,
            "pairing_mode": 1,
            "open": 0,
            "dfu_service": 0,
            "event_service": 0,
            "device_info_service": 1
        },
        "gatt_table_size": "0x700"
    }
}
