It took 5 years to discover that the seven hidden features of WeChat, each strong and practical

There are a lot of easy-to-use features on WeChat, but you don’t know every one.

Here, I will use it for 5 years to discover. WeChat seven hidden features, each strong and practical, learn to rise.

1, shortcut

2, shortcut icon

Based on the first feature, these shortcuts can also be split into a shortcut icon. If you click on these icons, press and hold the unreasonable words and then move to the blank, you can become an icon separately, use it more convenient.

3, folding group news

There are too many WeChat groups, and many are not common, but it is inconvenient to exit. But now you can choose a folding group message. If you don’t use the group chat, you don’t have to worry about excess messages.

4, care mode

There is a care mode in WeChat settings. After opening, the font, icons will become bigger, the color of the font and the color of the icon change, it seems more obvious.

It took 5 years to find that the seven hidden features of WeChat, every one is strong and practical, are you using it?

What is the millennium? A huge bug left at the beginning of the birth of the computer

To put it, in addition to social technology, in addition to truly learning computer professional, most people have some strangers for "millennium insects", even some people have never heard, do not know, users hear "insects" This word may also make a large pile of unidentified creatures, but in fact, "millennium worm" is not a creature, but a computer system created by humans.

The birth time of "Millennium Worm" is far from a so-called 1000 years. In fact, it is concerned that it is 21 years ago, and "Millennium Worm" is not like the netizen imagination, it is a similar "panda burning incense" Computer viruses have caused significant losses to humans at the beginning of the birth of the computer. It is exactly that it is a loophole of computer system designers, which is the system we are well known. "BUG"

Bug mother "Ge Lisi Hope"

Speaking of the history of the millennium has to mention a person, her name is "Ge Lisi Hope", people who have learned computer history should know that she has an outward in the computer field, called "BUG mother "

Geleis Hop was born in the United States in the United States in 1906, from a small way, especially the talent of math, in 1928, Hoop, who graduated from the Vasa College, has obtained the double bachelor degree in mathematics and physics. Later, she continued to study, six years later, becoming a small female doctoral mathematician, after 1939, the Second World War broke out, Hop was affected by the social environment, entered the US Navy system

Although Huof can’t kill the enemy because of women’s identity and physical problems, Hop is unable to kill the enemy. And sent to Havende Aiken’s hand as an assistant, and Howard is the manufacturer of the first general computer "Mark No." "Mark No." later.

Hop remained in the computer industry, Hop remained in the computer industry, because of the super high mathematics talent, her understanding of the knowledge of computer systems quickly, and became the most effective way of Howard’s hand, one is in progress "Mark 2" "In the operation experiment, the machine is inexplicably fault. Scientists find everything after the equipment, or Hop thought is fatigue, and found that there is a small bug in the computer system board, and she writes in the job note" because of a bug " (English in English), we interrupted the experiment "

This is the first "BUG" of the computer system in history. Hop is not only the first person who uses BUG to call the accident, but the earliest scientist manufacturing bugs for future generations.

"Millennium insect"

In 1957, after the end of the Second World War, countries around the world began to develop science and technology, and the research and development of computer systems in the United States has become flooded. The programming language has no uniform system, so the institution at the time. Invited Hope, I hope she can develop a general computer programming system, which is the COBOL language, which can write large-scale load procedures.

In addition to the changes in programming language, Hop is also significantly adjusted on the computer storage system. She is the world’s first developer who chooses 6 digits to store the date, like the count date we use 96.10.18 The representative is October 18, 1996, Hop is the starter of this counting method.

However, even Hope did not expect that she changed a small change in the date storage system, which actually triggered the world’s global system bug.

The principle of this bug is very simple, that is, the 6-digit storage date method, although some computer runspace, but every time you go to the millennium, the system will not recognize the problem, such as 6 digits in 2000 To store, it is 0000 years, and the intelligence of the computer at that time is not recognized that the month is 2000 or 1000 years, which leads to a major deviation in some calculation results.

Not only that, because the electrical system at home and abroad is already popular in 2000, and most of them use Hop-developed 6 storage methods, they have encountered bugs, and this will have once every 1000 years. The computer vulnerability is called "millennium insect"

Interestingly, when Hop-developed 6 stores, the United States "Bob" has discovered its major bug, but the people at the time did not think about it, because they think this vulnerability is a born year. I can’t encounter, so I am too lazy to solve, but it is better to hand it over to the future generation. I have not been released until 1990. The programmer in the world has not been released, so in the past 10 years, it is collapsed for the system. prepare for

Until 2000, the vulnerability of the millennium insects officially broke out, although many computer systems have collapsed, but it is better to prepare, so the impact of "millennium insects" is not big, and it has been in the past 20 years The engineers are constantly improving, even if it is once again outbreak, wait for 3,000 years, people still use it without a computer.

It’s just that we can’t be sure. In today’s less improved today, we will also have some "millennium insects", and do not want to improve after discovering, so that it will resolve the future generations?

Breaking the tradition, introducing a smart display, bringing you a wonderful life

Traditional shop advertising not only is not only logistics cost, and labor costs and technical costs are difficult to estimate, and the advertising effects of traditional models are also small. "Figure" is to break the imprisonment of traditional advertising thinking, helping merchants can achieve high-efficiency promotion targets for exposure and traffic guarantee on the basis of great reduction of promotional costs. "Figure to" project passes the "map to X1 box" coverage free laying makes the project’s extensive promotion, and its advertising screen is set in the gate of the Lujie shopping shop or the intensive space in the mall, and there is no more than 20 distances. Rice, firmly lock the shopping crowd, the explosive proof effect makes the customer are unforgettable. However, the premise of free laying is that there is one-third of the advertising screen, which is one of the important means of traffic change. When the business district of the city traffic center is "mapped" full coverage, then the immersion surrounding surrounding surrounding surrounding surrounding of the outlet can make the advertiser to achieve a full-scale exposure. This is the digital propaganda scene that "map". empire.

How India and Germany can work together to tackle climate change

For over a year now, India, Germany and the entire world have been in crisis mode. The Covid-19 pandemic has left no country untouched. It is safe to say, we will either beat Covid-19 worldwide or not at all.

The virus briefly drew attention away from another crisis — climate change and its impact. In South Asia and Europe, we have become used to extremely hot weather, flooding, dramatic depletion of groundwater tables and drought. Climate change could even stop the world from achieving the Sustainable Development Goals (SDGs).

We have agreed that global warming must be kept to well under 2 degrees Celsius and, if possible, to 1.5 degrees. Back in December 2015, 195 countries joined in Paris to sign an ambitious climate agreement. Each of those countries must deliver on their responsibilities. Climate change, too, is a crisis that can only be beaten worldwide or not at all.

India is one of few countries that looks set to deliver on the national goals it set itself as part of the Paris agreement. Compared to other G20 countries, its per capita emissions are very low.

At the same time, India must bear in mind the development interests of its large population. We firmly believe that sustainable growth and climate action go hand in hand. India now has the opportunity to make its massive investments in infrastructure over the next 15 years climate-smart and climate-resilient. This will also protect the interests of the most vulnerable sections of the population. Without India, the world will not be able to fight climate change. Without India, we cannot achieve the SDGs. That means that India has a leading international role to play in the global race to sustainability.

The EU has adopted an ambitious Green Deal to achieve net-zero greenhouse gas emissions by 2050 and to decouple economic growth from consumption of natural resources. Germany recently adopted laws on reducing greenhouse gases more quickly, achieving climate neutrality by 2045 and stopping the use of coal for electricity production by 2038.

As Deputy Ministers in Germany’s Ministry for Economic Cooperation and Development, we come to India with the greatest confidence in the country’s political process and to learn from India. We see our responsibility as an industrialised country to both forge ahead with greening our own economy and also support other countries.

In 2015, India’s Prime Minister and Germany’s Federal Chancellor agreed to further strengthen the two countries’ strategic partnership. On this basis, Germany and India have succeeded in building up a cooperation portfolio worth almost 12 billion euros. Already, nine out of 10 measures support climate goals and SDGs together.

Indo-German development cooperation focuses on three areas: The transition to renewable energies, sustainable urban development and sustainable management of natural resources. As a pioneer of energy transition, Germany is offering knowledge, technology transfer and financial solutions. Over half the Indian population will live in cities by 2050. Our cooperation efforts support Indian policies to find sustainable solutions for this growth challenge in the face of limited urban resources and climate change.

The pandemic has shown global supply chains are vulnerable. Yet, when it comes to agriculture and natural resources, there are smart solutions that are being tested in India and Germany for more self-reliance, including agro-ecological approaches and sustainable management of forests, soils and water. Experience in India has shown that these methods also boost incomes for the local population and make them less dependent on expensive fertilisers, pesticides and seed. We look forward to deepening the work in this area. This is related to international health policies. Through a One Health approach, which looks at the close connections between human and animal health within their shared environment, we want to help tackle the challenges posed by population growth, increased mobility, shrinking habitats, industrialised farming and intensive animal husbandry.

Ultimately, we believe that global climate goals and the SDGs can only be achieved through cooperation between governments, the private sector, science, and civil society. India and Germany have innovative economies and many highly-trained people. We should harness that potential even more.
