Now one day many people do freelance work

Now one day many people do freelance work. And Forex is one of the most popular freelance jobs that can be easily done from home. But I was looking for a broker who offered me a small investment. That's why I joined AAFX. Because this broker gave me a small investment in lots of lots. They also have other trading accounts like VIP, FIX and ECN accounts.

Do eyeglasses affect visual perception significantly enough to influence post-production work?

I have mild astigmatism and sometimes wear glasses or contact lenses. I've found that wearing a pair of glasses has mild visual distortions and chromatic aberrations compared to not wearing them or wearing contact lenses instead.

I'm curious how strong the glasses would affect the post-production, if any. Due to my (limited) experience, I do not see a significant difference between photos that I edited with glasses and without.

Curious as to whether different types of eyeglass lenses affect vision differently. For example, lens material and lens shape (for different types of visual correction).

Game AI too slow to work

I wrote Python code to play this scratch game.
However, it is too slow to work properly, as each picture when clicked takes a screenshot of almost the same thing

_ _ | ______
_ | ______


_ _ | ______
__ | _____

And so it clicks again because it thinks it's still deep enough to jump, so it's double dead.

Any ideas on how to improve the speed for it to work?
Here is the code:

#Circle on scratch destroyer
Import numpy as np #Numpy
import screenUtils #My own code, which retrieves the screenshot (no problem, the screenshots are lightning fast)
Sleep, time #sleep for sleep and time for time verification
from pymouse import Click PyMouse #Mouse
PyKeyboardEvent # Failsafe key from the Pykeyboard import is q
From threading, import the #Threading thread for the keyboard input and screenshot loop
m = PyMouse () #Init mouse
jumpHeight = 40 #Ho the player jumps with every click
class safe (PyKeyboardEvent): #I said it was safe because it is fail-safe
def xtra (self):
self.tog = False #Toggle
def tap (self, keycode, character, press):
"" "
Subclass this method with your key event handler. It is obtained
the key code associated with the key event and the string name for
the key if one can be assigned (keyboard mask status will apply). The
Argument & # 39; press & # 39; is true if the key was pressed, and false if the key was pressed
Key was released.
"" "

Algorithms – How a Merkle tree can work with graph data or a better data structure

I'll look at Blockchain and see how Merkle trees (or maybe Merkle DAGs) can fit into a chart data structure with circular references.

Suppose I have this data model:

var profile = {setting1: 123, email: & # 39;;}
var user2 = {}
var user3 = {}
var msg1 = {body: & # 39; foo & # 39;}
var msg2 = {body: & # 39; bar & # 39;}
var group1 = {name: & # 39; hi & # 39;
var group2 = {name: & # 39; world & # 39;}
var user1 = {messages: [ msg1, msg2, ... ] }

profile.user = user
user.profile = profile

msg1.sender = user1
msg1.recipient = user2
msg2.sender = user1
msg2.recipient = user3

group1.members = [ user1, user3 ]
group2.members = [ user1, user2, user3 ]

user1.groups = [ group1, group2 ]
user2.groups = [ group2 ]
user3.groups = [ group1, group2 ]

This is highly cyclical, but it really only has two or three levels of cyclicity. In reality, there could be extremely large and complicated cycles, but I do not want to make it too complicated.

Essentially, with the Merkle tree, you have a set of data blocks from which you can create the leaves of a tree and calculate hashes for each pair up to the top of the tree. However, if one of your blobs changes, you'll need to recalculate the entire path. When you insert a node, you may need to calculate more. And this is only for basic data blocks.

However, if you have chart data as described above, I am not sure what to do or if there is a better data structure. For example, if you change profile.emailThen you would assume that the profile has changed. However, I am not sure if we also say that "user" has changed because it was once removed. Similarly, maybe even "msg1" has changed, or "group" has changed, because user1 is linked to some of these links. Basically, the notion of a "single entity" in a diagram seems to collapse, and I'm not sure what to do. ask me, if

  1. Merkle trees are simply not good for this type of data structure.
  2. If there is a way to make Merkle trees work here.
  3. Or, if there are one or two better data structures for this type of data model that can achieve what the Merkle tree does best (especially to confirm that the data has not changed).

magento2.2 – Observer for the controller_action_predispatch event, which does not work for standard Magento2 REST APIs

I have created an observer for the event controller_action_predispatch, The observer works only for the front-end and back-end requests, not for standard REST APIs.

I put the file event.xml in the folder etc of my custom module.


Make the observer for the event controller_action_predispatch Working with REST APIs, what should I do?

How is it that the jobs that are simple and do not require a lot of work are dominated by women?

Your definition of "easy" may be a little selfish.

I've never heard anyone call a social worker's job "easy," a job that's predominantly female.

Anyone who describes the job of the K-12 teacher as "easy" has clearly not paid close attention.

Yes, it is true that most jobs that society has now labeled "women's jobs" do not require much repeal or (with the notable exception of care and social work). But occupations that do not sleep at night, disturb all aspects of your life, etc. are NOT easy.

It must be nice to work 8 hours and then not work for 16. For me, this seems to be the easy job.


proof of work – How to create coins from a cloned POW / POS Altcoin

I successfully cloned a POW / POS coin based on a composite coin, generated the Merkeroot and Genesis block, and a running gui purse on Ubuntu 16.04. The question now is, how would I start winning my first coin on testnet first. I researched and researched the internet, but most examples show how to build POW wallets like Litecoin in advance. Incidentally, I also cloned Litecoin 0.8 through a tutorial and preinstalled it using the setgenerate command. The problem with my cloned POW / POS coin is that there is no setgenerate command. Would anyone show me or help me on steps that I would have to do before the mine? Would this be possible by running 2 daemons from two virtual machines (i.e., Virtualbox) and setting one as a server and the other as a client?

Lens – Does Canon EF 50mm 1: 1.8 II work with Canon 200D?

I have a very similar camera (Canon EOS 2000D) and a similar lens (EF 50 mm 1: 1.8 STM). Both work well together. So the answer to your question is YesThe lens works with your camera.

You should know that the EF 50mm in a crop sensor camera such as 200D or 2000D corresponds to a focal length of 1.6 * 50mm = 80mm. So it's a mild telephoto lens.

In my opinion, it is a very useful lens, unless you plan to take indoor shots in a very small space. The focal length of 50 mm and the aperture of 1: 1.8 allow cool depth of field effects. Not only that, but the Canon 50mm lens is extremely cheap.

Note that the lens you are considering is the II model, not the STM model. The user manual of my 2000D camera warns:

If you are using the AF with one of the following lenses, use [Quick mode] is recommended. Autofocus with [FlexiZone – Single] or [Live mode] may take longer or the correct focus may not be reached: EF 50 mm 1: 1.8 II, (Some other lenses have been removed, but the 50mm STM model is not included in the list of lenses.)

… so focusing in live view mode is not as good as the STM model, unless you are using fast mode autofocus (I also use fast mode autofocus in live view mode). In addition, the STM model is better at taking videos because the focusing lens of the II lens is audible and can land in the audio track of the video.

Also note that the 50mm lens does not have image stabilization, although you probably will not need it for the 1: 1.8 aperture.
