## ❓ASK – Previous work experience helps in future or not? | Proxies123.com

Many people start business but they cannot sustain for long time. Unfortunately they have to quit the business and move to another. There are so many examples where people keep on trying to find a suitable business, and for that have to quit so Many other jobs.

When we quit a previous job or business, there might be some problem within ourselves, which led our business to collapse. Learnings from our own mistake will surely help, but do that help in future prospect? Does the past experience really helps in deciding our future prospects?

They’re a tradition that ” if you write any long-form content you should use 8-12 headers for a better result” More headers, more readers will understand the topic. Headers can increase the site’s useusability. But I think headers do not any kind of effect on SEO because they only topic’s subheadings.
What do you think about the headers? Are they really have an impact on the site’s SEO?

I think it’s useful and for Google, but and for people/readers to.

After all, these are not the only text/article writing rules that apply to SEO. The title of the article/text describes the topic of the article. In order to write a quality article/text, we plan a set of thoughts: outline, content, conclusion/conclusions. Adherence to these rules allows you to plan not only the content but also the brainstorming so that we do not deviate from the topic or expand too much. Thus, the title of the article/text indicates the main topic. We then divide that topic into paragraphs. After all, each topic can be described in different aspects – there are endless variants. Thus, the title, the titles of the paragraphs, and finally the conclusion – at the end of the article/text – are a summary of the whole topic written.
If we look at the article from the SEO side, we can use the title of the article and the titles of the paragraphs to place the main thematic keyword / LSI keywords in the written text.

In short about H tags using recommendations in web structure:
1. Primary keyword in URL and H1
2. Primary keyword at the beginning of title tag
3. primary keyword in first 100 words
4. Primary and secondary keywords in H2, H3 directly and with variations
5. LSI keywords in the content

In my opinion, H tags allow you to plan content /theme development in an orderly, planned, and structured way. With the help of H tags we can emphasize the most important places / main parts not only for readers/web users but and for Google

## Does social media marketing really helps in Business

Hi all forum friends
Can you tell me Does social media marketing really helps in Business?

## Program that helps you find the Meta of each key on your keyboard

I’m sure my topic words are completely wrong.Meta can’t be the right word.
I apologize.

Anyways I love using tiling window managers. Like Ratpoison or Spectrwm. But life intervened and kept me away from the computer and strictly to my phone for a few years.So I am very rusty to these window managers now. And openbox is great(Im sure someone would have brought that one up ;), but I like to have multiple managers to play with.

I used to use a program to find out what my Volume keys are, my media key, mute, and so on. I remember the particular program popped up two terminals I think? One would have you press the key, and the screen behind it would pop out the meta.Anyone know what I’m talking about, or something similar? I’ve searched multiple threads, but they’re all members telling other members that Alt is Mod1, or Mod4 is Super. But I’m looking for a program to do this for me.

Thank you for reading and thank you for any responses.

Oh…and what’s really weird, take spectrwm for example, Mod1+whatever will open the program I assigned to it, but then the very next Mod1+whatever won’t open my other program I assigned it too. And it’s not conflicting with another keybind.Which would think that’s whats happening, but a quick search in the config file shows not one confliction.

tl;dr Looking for a program to tell me what the meta is for each key on my keyboard

## exploit – Does my using of a chinese led kit for monitors helps people to intercept electromagnetic radiation from my monitor signal?

My system is compromised, should I look for rootkit or for other ways?
I have an instant leak of data even when my system internet cable is plugged off.
Monitor is the main suspect (2007 with chinese LED kit), videocard(don’t think so) is second,
Keyboard is the other.
How expensive would it be to intercept it? Data leaks to another floor, 3 meters to their equipment, near 1 meter are metal heater radiators of central heating which conduct signal.

If it is a rootkit, how can I check for it if free options doesn’t show anything?
Can it be some kind of RDP?

## project management – Does exist any methodology, which helps decide which elements to choose into the technology stack?

In most cases, it is prescribed what kind of programming language to use with what framework. In my question, I’m pointing to those situations when there is no requirement for the stack.

I understand that many people are limited by their previous experience, what kind of languages they used before, but I would like to abandon this factor.

When a project is starting and the participants have the freedom to select the elements of the technology stack, they have to decide somehow why do they choose one option despite the other alternatives.

Due to my previous search, I identified some website, which has a categorization and review system for technologies:

The list is not complete, and I’m curious if there is a “best” for these “comparative” sites. Like there is a “best” for searching something on the internet, although it has working and available alternatives.

To show an example: It’s about a web development project, there is a frontend, backend, and a database. It must be determined which language and technologies to use for each part of the system.
It is obvious that popularity and support is an important factor, but that’s lead to my question of detail:

How can someone determine the popularity and supportability of the options?

## How attributes helps us to allow column interchange in a relational database?

A relation on two sets A and B is defined as the subset of the cartesian product A X B = {(a,b), a $$in$$ A and b $$in$$ B}.

A database is also a relation and each entry is an ordered tuple respecting the cartesian product.

Now, interchanging the rows and the columns of a database does not change it. I can understand that a relation is just a set of tuples (called as row) so the order of elements in a set does not matter and hence row interchange will not pose a problem. But column interchange conflicts with the idea that a particular entry of the database is an ordered tuple.

So, attributes are used to tackle this problem. This is what I was told (verbatim):

Example table:

Name    Roll No.

Alex       2

Fred       5

Nate       7

=> Fix a set C also called the index set ( here it can be {1,2} or {Name, Roll No.} )

=> Consider:: {A i | i $$in$$ C}, A i is the “type” of the attribute i (here that is A 1 = String and A 2 = Integer).

=> The cartesian product: $$Pi$$ i A i is seen as the collection of functions f : C $$to$$ $$cup$$ i A i such that f ( i ) $$in$$ A i

I was told that this definition of the cartesian product will allow us not to worry about the position of the column ‘Name’, etc. But I did not understand why. I would appreciate any kind of help and I apologize in advance for bad/incorrect formatting.

## php – Browser loses connectivity to website. Switching browsers helps, but just temporarily

This problem shows up when I have poor WiFi connectivity, or no WiFi. I’m using my android phone, with chrome browser, to connect to my website (LAMP), and limping along with poor response, but happy and productive. But then I can’t reach the website at all. I can reach other websites but not my website. I’ve tried closing my chrome and reopening it. If I wait several minutes I can usually get back to my website. However, my application is time-critical and this delay is very disruptive. I’ve found that when I can’t get through on chrome, if I immediately switch to the Samsung browser (also chromium-based) I can regain access to the my website right away. Then after several minutes, I might lose access again. I can immediately regain access if I switch back to chrome. So the problem is not chrome itself. Perhaps if I had 2 instances of chrome, say chrome and chrome-beta, I could switch between those successfully. But I haven’t tried that experiment. In long sessions, with very bad connectivity, I have to switch browsers about every 5 minutes.

It seems like the bad connectivity causes Apache to temporarily ignore me. Perhaps some mechanism whereby the socket (or some other intermediate-entity, like a PHP worker) is marked “bad” but not closed. So that intermediate-entity has to timeout before the same browser can connect again. Perhaps by switching browsers, a new intermediate-entity is opened and the old one abandoned. I’m just guessing at a possible mechanism.

I’ve looked at apache error log, apache access log, php error log and php-fpm error log. I don’t see anything that coincides with my connectivity problem. My php max_execution_time is set to 120. I’m not hitting that as far as I can tell.

## c++ – Need helps for eye tracking calibration using std::thread and std::condition_variable

I am a newbie in std::thread and std::condition_variable.

I would like to use 2 threads: one for display (void showCalibration()) and the other for processing (void CaptureFrame()). These threads access a global variable (temp_pupil).

The display thread will clear the variable after a specific time to get the data (pupil) from processing thread (during that time):

``````#include <opencv2/core/core.hpp>
#include <iostream>
#include <mutex>
std::vector<cv::Point2d> temp_pupil;
std::mutex mu;
std::condition_variable cond;

void showCalibration()
{
for (int i = 0; i <= 9; i++)//plot 9 points sequentially
{

std::unique_lock<std::mutex> lk(mu);
{
temp_pupil.clear();//prepare for get new data
}
lk.unlock();
cond.notify_one();//signal CaptureFrame() to capture data

lk.lock();
{
while (temp_pupil.empty())
{
cond.wait(lk);//wait CaptureFrame() to end current point
}
std::string cal = std::to_string(temp_pupil.size()) + "Cali" + std::to_string(i) + "n";
std::cout << cal;//print
}
lk.unlock();
}
}

void CaptureFrame()
{
cv::Point2d pupil;
for (int i = 0; i <= 500; i++)
{
std::unique_lock<std::mutex> lk(mu);
{
pupil = cv::Point2d(i, i);//create data
temp_pupil.push_back(pupil);//get data
std::string cap = std::to_string(temp_pupil.size()) + "Captue" + std::to_string(i) + "n";
std::cout << cap;//print
}
lk.unlock();
cond.notify_one();//signal showCalibration() to end current point
}
}

int main()
