Slowing Aging
|
||||||
|
=============
|
||||||
|
|
||||||
|
- Avoid DNA damage (wear sunscreen)
|
||||||
|
- Eat less - caloric restriction
|
||||||
|
- Eat less protein
|
||||||
|
- Do exercise (HIIT)
|
||||||
|
- Be cold
|
||||||
|
- Be hot
|
||||||
|
|
||||||
|
... these trigger longevity genes to trick body into preserving genome
|
||||||
|
|
||||||
|
|
||||||
|
Reversing aging
|
||||||
|
===============
|
||||||
|
|
||||||
|
Theory
|
||||||
|
------
|
||||||
|
|
||||||
|
- Shinya Yamanaka discovered 4 factors that reset epigenome of cell back to pluriportent stem cell
|
||||||
|
- Myc, Oct3/4, Sox2 and Klf4
|
||||||
|
- dont do it all, would turn into tumor
|
||||||
|
- suggests there are ways to revert cells and reverse ageing
|
||||||
|
- David Sinclar's lab reversed aging in old mice so they could see like they were young again
|
||||||
|
- used 3/4 of the reprogramming factors, not Myc as causes cancer
|
||||||
|
- can turn system on and off to limit reversal
|
||||||
|
|
||||||
|

Notes:
|
||||||
|
Calorie restriction, mostly vegetarian diet, avoid sugar and carbs.
|

|
On weekends, he exercises at the gym and then sits in a hot sauna before plunging himself into an ice-cold pool, as well as tracks his biomarkers regularly.
|
||||||
|
Takes vitamin D, vitamin K2, and aspirin.
|

OpenVPN
|
||||||
|
=======
|
||||||
|
|
||||||
|
Setup:
|
||||||
|
$ sudo su root
|
||||||
|
- follow steps here:
|
||||||
|
- https://wiki.debian.org/OpenVPN#TLS-enabled_VPN
|
||||||
|
- skip editing vars
|
||||||
|
- add random data to /etc/openvpn/easy-rsa/pki/.rnd to get rid of error messages
|
||||||
|
- use the # ./easyrsa [command] methods
|
||||||
|
- encrypt CA with password
|
||||||
|
- build the optional intermediate CA
|
||||||
|
- https://wiki.debian.org/OpenVPN#Static-Key_VPN
|
||||||
|
- improves security
|
||||||
|
- set auth SHA256
|
||||||
|
- save config file to /etc/openvpn/server.conf
|
||||||
|
- * set root's shell back to /bin/false *
|
||||||
|
|
||||||
|
Static IP:
|
||||||
|
- create a client (ie. "mediaserver") with easyrsa
|
||||||
|
$ mkdir /etc/openvpn/ccd
|
||||||
|
- edit /etc/openvpn/ccd/mediaserver:
|
||||||
|
ifconfig-push 10.8.0.100 255.255.255.0
|
||||||
|
- edit /etc/openvpn/server.conf:
|
||||||
|
client-config-dir /etc/openvpn/ccd
|
||||||
|
|
||||||
|
Routing / port forward:
|
||||||
|
- edit /etc/sysctl.conf:
|
||||||
|
net.ipv4.ip_forward=1
|
||||||
|
- edit /etc/default/ufw:
|
||||||
|
DEFAULT_FORWARD_POLICY="ACCEPT"
|
||||||
|
- edit /etc/ufw/before.rules at the top:
|
||||||
|
*nat
|
||||||
|
:POSTROUTING ACCEPT [0:0]
|
||||||
|
# ssh port forwarding
|
||||||
|
-A PREROUTING -d 159.203.223.101 -p tcp --dport 43655 -j DNAT --to-dest 10.8.0.100:43655

|
||||||
|
# Allow traffic from OpenVPN client to eth0
|
||||||
|
-A POSTROUTING -s 10.8.0.0/8 -o eth0 -j MASQUERADE
|
||||||
|
COMMIT
|
||||||

|
- source: https://gist.github.com/kimus/9315140
|
||||||
|
|
||||||
|
Systemd fix:
|
||||||
|
- ensure config file is at /etc/openvpn/server.conf
|
||||||
|
$ sudo systemctl start openvpn@server
|
||||||
|
$ sudo systemctl enable openvpn@client
|
||||||
|
$ sudo systemctl daemon-reload
|
||||||
|
$ sudo service openvpn restart
|
||||||
|
- verify stop / start with ps aux | grep openvpn
|
||||||
|
- do same for "client"
|
||||||
|
- source: https://ubuntu.com/server/docs/service-openvpn
|
||||||
|
|
||||||
|
Systemd client:
|
||||||
|
$ sudo mv vpn2-client.ovpn /etc/openvpn/client.conf
|
||||||
|
$ sudo chown root:root /etc/openvpn/client.conf
|
||||||
|
$ sudo chmod 600 /etc/openvpn/client.conf
|
||||||
|
- if there's a password:
|
||||||
|
$ sudo -E vim /etc/openvpn/auth.txt
|
||||||
|
$ sudo chmod 600 /etc/openvpn/auth.txt
|
||||||
|
- add password to file
|
||||||
|
- add "askpass /etc/openvpn/auth.txt" to config file
|
||||||
|
- set up systemd:
|
||||||
|
$ sudo systemctl start openvpn@client
|
||||||
|
$ sudo systemctl enable openvpn@client
|
||||||
|
$ sudo systemctl daemon-reload
|
||||||
|
$ sudo service openvpn restart
|
||||||
|
|
||||||
|
Disable routing traffic over VPN:
|
||||||
|
- remove all "redirect-gateway" lines in client config

|
- vpn settings, add
|
||||||
|
- import from file, select vpn2-client.ovpn
|
||||||
|
- add missing private key from /home/tanner/.cert/nm-openvpn/
|

Notes from Andy
|
||||||
|
---------------
|
||||||
|
|
||||||
|
Mastering your mind:
|
||||||
|
- can you control yourself?
|
||||||
|
- can you sit still physically?
|
||||||
|
- can you control your mind?
|
||||||
|
- can you concentrate on a simple object and nothing else?
|
||||||
|
- can you have no thoughts?
|
||||||
|
- can you free your mind from remembering the past or future?
|
||||||
|
- can you have no visual images / sounds?
|
||||||
|
- can you stop your inner monologue?
|
||||||
|
|
||||||
|
|
||||||
|
How to meditate:
|
||||||
|
- these steps are very gradual, not distinct steps:
|
||||||
|
- master focusing in the present (1-2 years)
|
||||||
|
- disregard the past and future
|
||||||
|
- focus on noises in the present. can jump around or listen to all.
|
||||||
|
- on failure gently pull back to the present
|
||||||
|
- mastery when you can do this for an hour
|
||||||
|
- can start with shorter sessions
|
||||||
|
- master focusing only a single element in the present
|
||||||
|
- for example, your breath
|
||||||
|
- master stopping the monologue
|
||||||
|
- stop talking to yourself
|
||||||
|
- stop making comments
|
||||||
|
- stop the chatter
|
||||||
|
- master total absorption into that single element
|
||||||
|
- deeper focus into the element
|
||||||
|
- Samadhi state
|
||||||
|
- can only experience your own, dont read the wiki
|
||||||
|
- Andy reached this only once, he felt omnipotent
|
||||||
|
|
||||||
|
- this becomes an intrinsic skill like talking and walking rather than a motor skill like throwing?
|
||||||
|
- if you dont use it you lose it?
|
||||||
|
- one you reach Samadhi your mind always meditates

Reviews
|
||||||
|
-------
|
||||||
|
|
||||||
|
Joplin:
|
||||||
|
- UI is very fast
|
||||||
|
- has its own sync server now, wait to mature?
|
||||||
|
- scroll in render view glitchy / laggy when zoomed
|
||||||
|
- WYSIWYG editor breaks some markdown
|
||||||
|
- clicking links in WYSIWYG requires ctrl
|
||||||
|
- can't see note names in notebook tree, so will be hard to find
|
||||||
|
- maybe that's better?
|
||||||
|
- mobile app lacks WYSIWYG
|
||||||
|
- mobile app md editor scroll shitty
|
||||||
|
- slow to edit notes in mobile app
|
||||||
|
- white flashes on dark mode desktop theme when switching notebooks
|
||||||
|
- Todo feature is cool. can make each note a todo and use the body to add context / info
|
||||||
|
- easy to rearrange todos
|
||||||
|
|
||||||
|
Obsidian:
|
||||||
|
- highly reviewed, looks sexy but needs more contrast
|
||||||
|
- no WYSIWYG editor yet - planned
|
||||||
|
- has graph and backlinks
|
||||||
|
- not open source
|
||||||
|
- files stored as plain text
|
||||||
|
|
||||||
|
|
||||||
|
Wiki.js:
|
||||||
|
- Supports LaTeX
|
||||||
|
- Support Markdown (it also supports formats such as html)
|
||||||
|
- Works in-browser (and therefore can be accessed on any device)
|
||||||
|
- Editing is easy (although this sounds like a "duh" feature, many self-hosted note apps are more like static site generators)
|
||||||
|
- Uploading files is simple
|
||||||
|
- Has multiple backup options (I use GitHub and .gitignore the textbooks)
|
||||||
|
|
||||||
|
|
||||||
|
Boostnote:
|
||||||
|
- no mobile support

||||||
|

|
||||||
|

|
||||||
|
- parts of UI not updating like archived notes

|
- randomly refreshes the page
|
||||||
|

|
||||||
|
- today note button is slow to load
|
||||||
|
|
||||||
|
Simplenote:
|
||||||
|
- not self-hosted
|
||||||
|
- no folders
|
||||||
|
|
||||||
|
Turtl:
|
||||||
|
- buggy app
|
||||||
|
- bad organization system
|
||||||
|
|
||||||
|
Org-mode
|
||||||
|
- needs emacs
|
||||||
|
|
||||||
|

The perfect note-taking app:

https://www.youtube.com/watch?v=wpcVQeF07G4

- gardener: likes connecting ideas in their own way -> roam
|

Assigning timezone to parsed string:
|
||||||
|
- example, you get a text timestamp and parse it with strptime
|
||||||
|
- solution:
|
||||||
|
t = datetime.strptime(timestamp, '%Y-%m-%d %H:%M:%S')
|
||||||
|
tz = pytz.timezone('America/Edmonton')
|
||||||
|
result = tz.localize(t)
