❓ASK – How to manage your emotions in cryptocurrency Trading? | Proxies123.com

One of the most important skills to have when trading in cryptocurrency is to be able to control your emotions. This ensures that you do not panic buy or panic sell any of your cryptocurrency coins. Typically there is a drop in the price of any cryptocurrency at any given point along the course of that cryptocurrency being traded. When you panic you tend to sell the coin prematurely and as a result you make a loss. What tactics do you use to try and prevent panic trading?

I personally set myself goals on a target price i want to sell at, or buy at, and stick to it, based on my analysis. This way despite how i am feeling, i don’t do these transaction until these predefined markers are met.

How I create store and manage my passwords

What method do you use for storing and remembering your numerous passwords?
Here is what I do.

I use Lastpass, a third-party password manager that’s also cross-platform and cross-browser, unlike the built-in browser password managers limited to the browser they are installed in.

For instance: I use Google Chrome on my laptop and can access my passwords in any browser, on any platform.

My password manager creates the password and has the ability to control how long it is and what type of characters it contains.

This is how I store create and manage my passwords.


rest – How to manage primary keys in CQRS

I’m building a backend following the CQRS pattern and I don’t know how to manage properly the primary keys (surrogate keys) between the command and query databases.

For example: I have a model with two different tables in each database. When I want to update the model in his different tables, each one doesn’t have the same ID (this is not my real schema):

players (cmd db)
| id | name | wins |   email   |
  1    Mark   200    mk@kogames
players (query db)
| id | name | wins | role_power | role_name | email |
  12   Mark   200      2120         melee   mk@kogames

As you can see Mark has two different IDs: 1 and 12. What are the recommended strategies in order to service CRUD operations and reference both registries properly? I was wondering if store both keys in any kind of storage as follows would be well-suited:

|   email   | cmd_id | query_id |
  mk@kogames     1        12

But it doesn’t seems to be a well designed solution.

design – How to run and manage multiple instances of an application (different start params) on multiple servers?

Our main (C#) application:

  • takes in parameters and starts working (batch processing, takes anywhere from minutes to hours)
  • up to x instances of said application per server
  • instances are started by users from our front end by making a request to a “master” on a server (really bad load balancing is just one of the problems).

The application itself is really simple. The instances themselves are “stateless”, meaning it doesn’t really matter if they do fail as long as they are being restarted with the same parameters. The application is also pretty lightweight.


  • deployment of the main application is done manually, by literally uploading it to servers and changing the application path the “master” uses to launch the instances
  • if an instance errors for whatever reason, healthchecks fail and the database entry for the instance is being deleted -> users need to manually restart the application since our backend isn’t capable of restarting the instance on another server.

A dream would be having a single endpoint on to which we pass the starting parameters, and a framework (or whatever) takes care of the actual provisioning and error handling. Maybe restarting an instance automatically on another server if one should decide to spontaneously fail.

Docker came to our minds, but we thought this would only really help us in terms of deployment.

A push in to the right direction would be wonderful!

iphone – MacBook M1 Big Sur crashes every time when I open “About This Mac -> Storage -> Manage”

Background: I’m using a MacBook Pro with M1 chip and Big Sur V11.1 (got it last month). One thing really annoys me is that when I connect my iphone, sync starts automatically and it takes up 20GB to when all iphone files are backed up.

Issue: So I wanted to delete the sync files using “Reduce Clutter” in “About This Mac -> Storage”. It worked fine for two weeks after I purchased the MacBook, but recently it starts to crash every time when I open “About This Mac -> Storage -> Manage” and I wasn’t even able to get the time to click “Review Files” under “Manage”. I tried to restart the system but had no luck at all.

Help: Does anyone else encounter the same issue? How to resolve it? Is there a way (say, command line) to delete synced iphone files without clicking “About This Mac -> Storage”?

“Manage-> Review Files” is a really convenient way to view and remove redundant files to save storage. It would be great if there is a way to revive that functionality if possible.

Thanks in advance!

key management – How can I store and manage my GPG key pair securely?

I’ve taken measures and thoughts on how to securely store and manage my key pair. In the process of it a few questions arose, which I’m not capable of answering yet. My key pair will be used to encrypt passwords and documents of banks, insurances, invoices, photos and the like. All this data is not publicly available. It is stored in a cloud with password restricted access. I’m evaluating right now, which one fits best.

This is how I set up my key pair:

# Generated a key pair in the past, following general tutorials
gpg> list
sec rsa2048/9AB628FC04C23871
    created: 2019-02-29 expires: 2022-02-29 usage: SC
    trust: ultimate    validity: ultimate
ssb rsa2048/17832C40CF826BA9
    created: 2019-02-29 expires: 2022-02-29 usage: E
( ultimate ) (1). Thomas Kelly <Tkelly@ua-corp.com>

> cryptsetup close data
> cryptsetup luksFormat /dev/sdb1 # pw ...
> sudo cryptsetup open /dev/sdb1 data

Then I went on and exported my keys towards this device, I’ve created. After I got used to it, that private keys are always a little bit different from another and you can’t export your sub-public key, the following questions remained:

  1. Are both of the following commands returning the ssb key (17832C40CF826BA9)?
gpg --export-secret-keys 17832C40CF826BA9
gpg --export-secret-subkeys 9AB628FC04C23871
  1. Is it fine to remove the key 9AB628FC04C23871 from my system, after I backed it up on the drive, created above?

  2. Should I save a revocation certificate with it?

  3. This key pair once expired and I changed the expire date. I can’t remember correctly, but I’ve found two additional certificates lying around that seem to be these old expires certificates. I’ve read that the process of changing the expiring value creates new certificates. Can you confirm this?

  4. I want to have two certificate stores like this on different locations. I’d renew the key on a yearly base. Should I use paperkey or the same digital method above?

sharepoint online – SPO CSOM Powershell manage folders with # and % in the name

I’m writing a CSOM PS script to create folders in a doclib, and set permissions on them.

Anything works fine except when the folder name contains a %

I am able to create the folder using ResourcePath, FolderCollectionAddParameters and AddUsingPath following this article

But I can’t get access to the folder using GetFolderByServerRelativeURL method.

The code is the following :

$folderurl="/sites/MySite/MydocLib/MyFolder %1"
$rpFolder = (Microsoft.SharePoint.Client.ResourcePath)::FromDecodedUrl($folderurl)
$CurrentFolder = $ctx.web.GetFolderByServerRelativeUrl($rpFolder)

And I get a “file not found” error.

Any help will be appreciated
