How to do a screenshot on a Mac

On a Windows computer, you’ll find that there is a keyboard key for taking screenshots (the Print Screen key). In the MacBook it looks a little different…

This is because on a Mac, you use a set of keys to capture the screen in various ways. Although the sound of a single key is simply great, the Mac printing method is much smarter. The Mac screenshot has many options, so we’ll discuss them all here.

How to take a screenshot on a Mac

To take a screenshot, press and hold these three keys simultaneously: Shift, Command and 3. If you see a thumbnail in the corner of the screen, click it to edit the screenshot. You can also wait until the screenshot is saved on your desk.

Capturing a specific part of the screen

If you want to capture a small part of the screen, you can do it as follows:

  • Press Command + Shift + 4. The cursor will change to + and you can click and drag to select a specific part of the screen.
  • How to take a screenshot of a window or menu
  • Open the window or menu you want to capture.
  • Press and hold these keys simultaneously: Shift, Command, 4 and spacebar. The indicator will take the shape of a camera. To cancel the screen capture, press the Esc (Escape) key.
  • Click a window or menu to take a screenshot. To exclude window shadow from the screenshot, press and hold down the Option key while clicking.
  • If you see a thumbnail in the corner of the screen, click it to edit the screenshot. You can also wait until the screenshot is saved on your desk.

macOS Mojave and the new screen capture interface

Now we also have the option of calling a special interface that allows you to support all possible screenshot modes.

After pressing the key combination Shift + Command + 5 we will see a special bar with icons allowing us to perform some interesting screen-related operations.

We can do the following with the new screenshot tool:

  • take a screenshot of the entire screen;
  • take a screenshot of the selected window;
  • take a screenshot of the selected piece of screen;
  • perform video recording of activities performed on the screen;
  • perform video recording of activities performed on the selected screen section.

 

Change the default location for saving screenshots in macOS

Screenshots are saved to the system desk by default. If you would like to change it and, for example, save all screenshots to one folder on your desk, you can do it as follows:

  • Create a folder where you want to save the screenshots, name and location are optional. For example, I will use the folder name “Screenshots”.
  • Open Terminal – you can do it by choosing the keyboard shortcut Control + Space (you will open Spotlight this way), then enter “terminal” in the search bar and press Enter.
  • Copy the following command: defaults write com.apple.screencapture location and paste into the terminal window. Make sure you have one space after the command.
  • Move the created “Screenshots” folder to the terminal window, as a result, the path to the “Screenshots” folder should appear after the command.
  • Press Enter.

What is abstract

The abstract is a brief discussion of the scientific text, and thus an incentive to read it. It should interest the reader, and at the same time strictly apply to what is contained in the article. It is not the same as the abstract and should not be used to summarize the full text.

Why write abstracts

The main purpose of the abstract is to summarize a longer text or statement. There is a reason why abstracts have a limited number of words or characters. It should be short and specific.

The recipient is to find what he is looking for in the abstract. And what do you usually look for?

  • tips on whether the publication is a theoretical consideration or a summary of empirical research
  • information on what the study was about
  • information on the method used
  • test results
  • conclusions from the study

Types of abstracts

Abstracts can be divided into two types:

Common errors found in abstracts

  • We also do not refer to tables and charts, or our other texts.

What time does the stock market open

0

In almost every country with a functioning free market economy, stock exchanges operate on which shares, bonds, commodities, derivatives and other financial instruments are traded. Nearly 40 percent of global stock trading is concentrated in North America. 33 percent are Asian markets, 19.5 percent of the turnover is on stock exchanges in Europe. What time does the stock market open?

Asian session – Tokyo

What hours does the Asian session take place? It is assumed that it lasts between 23:00 (opening of the Sydney stock exchange) to close the trading session in Tokyo – 10:00 in the morning.

Japan is the key market for this session. The Tokyo Stock Exchange, founded in 1878, is the third largest stock exchange market capitalization – $ 6.2 trillion (as of April 30, 2018) – second only to the New York Stock Exchange (NYSE) with capitalization of 24.2 bn dollars, and the second US NASDAQ stock exchange (11.8 bn dollars).

Asia is not only Japan, but also two strong stock exchanges from China (Shanghai $ 5 trillion; Shenzhen $ 3.5 trillion capitalization), one of Hong Kong ($ 4.4 trillion) and closing ten of the largest stock exchanges in the world – Bombay Stock Exchange (2 , $ 29 trillion).

Despite having as many as 5 exchanges on the list of top 10 exchanges, the Asian session is not very popular among investors on the forex market. This is mainly due to low liquidity, which automatically translates into higher spread costs.

European session – London

The European session starts with the start of listing in London at 9:00 am Polish time and lasts until 5:00 pm CET. At the same time, quotations are starting in other European countries, volatility on the currency market is increasing. Particular volatility is observed on pairs related to the euro such as EUR / GBP, EUR / JPY, or EUR / USD. This is the effect of transferring funds from individual exchanges. During the European session, market liquidity is high and spreads are narrow. Over time, volatility gradually decreases. Investors expect stronger movements on currencies, which may be visible when the US session begins.

American session – New York

The American session starts at 8:00 local time (EDT) and 14:00 European time (CET). Ends at 22:00 CET.

They include in its composition, among others Chicago and Toronto stock exchanges. On the other hand, the most important exchanges for this session are the New York stock exchanges: NYSE and NASDAQ. The latter, despite its fairly short history – it began operating only in 1971, and in 2006 obtained the appropriate stock exchange licenses – it quickly became the second largest stock exchange in the world.

The opening of the American session is very similar to that of the Old Continent. The first 2-3 hours are filled with many transactions with huge volumes, rapid directional movements and volatility. This is not only due to the fact that these two sessions overlap, which affects a larger number of investors, but also due to the publication of macroeconomic data.

 

Brain aneurysm symptoms

Brain aneurysm symptoms

Brain aneurysm is a disease of the blood vessels that supply blood to the brain. As a result of the segmental weakening of one of the layers forming the artery wall, it becomes prominent and transforms over time into an intracranial, celebral aneurysm. What are brain aneurysm symptoms?

Brain aneurysm – general information

The causes of brain aneurysm include, first of all, congenital predisposition – genetically determining the quality and strength of the arterial wall and atherosclerosis, as well as hypertension.

Due to the structure and shape, we divide aneurysms into: baggy (representing 80 percent of all lesions) and much less frequently occurring – fusiform. Regardless of the type, the mechanism of aneurysm formation is similar – under the influence of blood pressure, they constantly increase until they eventually burst, leading to bleeding or subarachnoid hemorrhage. It is the extravasation of blood from a ruptured vessel (aneurysm) into the subarachnoid space of the brain or spinal cord. Untreated subarachnoid hemorrhages are the cause of high mortality, which is why it is so important from a clinical point of view to quickly make a diagnosis and implement appropriate treatment.

Brain aneurysm symptoms

Causes of brain aneurysm

One theory is that the cause of cerebral aneurysm is a congenital abnormality of cerebral arteries, in which there is less muscle and elastic fibers in the bifurcation of the artery. Such a place is weaker and undergoes gradual exposure under high blood pressure. Confirmation of this theory is the fact that in families where spinal hemorrhages previously occurred, brain aneurysms more often appear.

In addition to the deficit in the structure of the middle membrane and the elastic inner membrane of the vessel, other causes of aneurysms are also listed:

  • developmental abnormalities in the area of ​​the arterial circle of the brain,
  • hypertension,
  • inflammation in the walls of the vessels,
  • hereditary factors.

Aneurysms arise for a long time, hence they are most often detected in the fourth, fifth and sixth decades of life, and only sporadically occur in newborns.

Brain aneurysm rupture

The risk of a crack depends primarily on its properties and the patient. Women and the elderly are more at risk. Family predispositions also affect (relatives of people with subarachnoid bleeding are several times more likely to develop the disease). Factors that may predispose for cerebral aneurysm rupture include hypertension, and prognosis is exacerbated by smoking and alcohol abuse.

Cracks usually occur: during physical exertion, drinking coffee, blowing the nose, sexual intercourse or strong nervousness.

Treatment

There are two methods of treating brain aneurysms: surgical placement of the aneurysm neck (surgical opening of the skull) and a neuroradiological procedure called embolization – a procedure that does not require opening the skull by filling the aneurysm with springs using a catheter inserted through the femoral artery.

 

Tips to Find the Perfect Remote Control

Tips to Find the Perfect Remote Contro

Regardless of whether you are new to radio controlled cars or if you have been enjoying them for quite some time, one of the decisions you must make is choosing the one that is best for you. More than likely, you have already watched some videos on YouTube or elsewhere, and they can whet your appetite to what is available. Sooner or later, however, you’re going to need to make the decision and put down the money to buy the car. How can you make that decision?

The following tips can help to guide you in making the right choice for the RC car that fits your needs. Regardless of whether it is a truck, car, buggy or anything else, choosing the right one will help you to enjoy the hobby to the full.

One of the most important things to consider is the type of fuel that is used for your best cars that are remote controlled. Some are powered by gas, but others have a mix of gas and oil. There are also RC cars that are using nitromethane, typically referred to as Nitro or glow fuel. This type of fuel can be found many RC stores or you can purchase it online, so either gas or Nitro would be just as convenient.

One of the reasons why you may want to choose gas over Nitro is because of the weight of a Nitro powered RC car. They tend to be heavier, so they are easier to break when you do happen to crash one. They also have more problems with spills and leaks, which is a consideration as well. That being said, Nitro powered cars tend to be more powerful, so it is a personal choice.

Another option is to choose an electric powered RC car. This is a good option if you are a beginner, but some of the higher-end models can do quite well. One of the benefits of using an electric powered RC car is the fact that it will work right out of the box after it is charged. They are also easier as far as maintenance is concerned and less expensive. You will have less power in most cases, however, and they don’t have that RC car noise that you will find in a gas or Nitro model.

You should also consider the size. RC cars come in various sizes that are typically rated as 1/16, 1/10, 1/8 or 1/5. 1/5 is the largest, but if you go with a smaller size, you may not be able to upgrade it as readily.

These tips can go a long way in helping you to determine which RC cars are going to be the best for you. When you keep everything in mind, the size, speed, and type of fuel, you will find that there are options out there available for the beginner to the advanced user. Choose the right car and enjoy what this hobby has to offer

Get The Most Value For Your Marketing Dollars With Social Media And SEO

0
SEO

Every business usually has a fixed budget for marketing, and they want to make the most of it. In today’s digital world, there are many different marketing channels available to businesses for getting leads and building their brand.

Two of the most important marketing channels when it comes to digital media include search engine optimization and social media marketing. Many businesses often want to know whether they should invest their marketing budget in social media or SEO to get the most value for their marketing dollars.

The article below will help you decide what is best for your business when it comes to digital marketing.

Benefits of Investing in SEO

Search engine optimization or SEO is the process of optimizing a website to get more targeted traffic from search engines by gaining high rankings for targeted keywords in the search engine result pages.

One of the biggest benefits of investing in SEO is that the search traffic is always increasing. Most people carry a smartphone these days, and they tend to find local businesses on their phone. Many research studies have shown that high search engine rankings also drive offline traffic to stores which mean even if a company does not sell a product or service online, they can still benefit by investing in search engine optimization.

Another big benefit of investing in SEO is that it is one of the most cost-effective ways to get highly targeted traffic to a website as compared to some of the other marketing channels. This is the reason that Google has become one of the most valuable companies in the world as almost everyone uses their search engine to find relevant products and services.

High rankings in search engines also help in increasing brand awareness as people trust the top search results. For instance, if you are a wedding photographer, and your website ranks high in the search engine result pages when someone searches for keywords related to wedding photography in your location, it creates a positive impression in the minds of the user even if they do not call you immediately.

In simple terms, high ranking websites are seen as more trustworthy by consumers.

Benefits of Investing in Social Media

The popularity of social media can be gauged from the fact that there are several social media platforms with hundreds of millions of users. In fact, the biggest social media platform, Facebook, has recently announced that they have over 2 billion members worldwide. In other words, you will be hard pressed to find someone who is not present on one or more social media platforms.

The biggest benefit of investing in social media is that potential consumers are already there, and you can take advantage of their presence by reaching them directly on various social media platforms.

Also, social media presence is ideal for building and enhancing your brand. Over the years, social media has also emerged as one of the best ways to bring high-quality traffic to your website.

Social Media and SEO Work Together

As far as choosing between social media and SEO is concerned, these two marketing channels complement each other. In fact, it won’t be wrong to say that SEO and social media drive each other. Therefore, it is important for businesses to invest in social media as well as SEO to reach the widest audience.

If your business maintains a presence on all the major social media platforms, it will become easier for your business to dominate the first page of search results for your brand. Major search engines such as Google as well as Bing index social media posts which mean if you include relevant phrases in the social posts, these may rank high in the search engine result pages and send more traffic to your business website.

Social media also helps with search engine optimization as informative posts on social media platforms tend to be shared by users which in turn drive high-quality links to your business website. Similarly, high ranking web pages on search engine result pages are shared by users on their social media profiles which drive more shares, and more traffic to your website.

Conclusion

Overall, your digital marketing strategy should be comprehensive and should include social media as well as SEO. Creative and well-crafted content will not enhance your social media presence by increasing shares but will also help your SEO efforts by getting more links from other authority domains.

How to build a deck

The wooden terrace is a real decoration of every home. It is timeless, well suited to all home arrangements, and its construction can be an interesting challenge for you. How to make a deck and what should you remember about? 

How to build a deck?

Wooden terraces are eagerly built, because their implementation is not too laborious. However, it requires the selection of a suitable wood species and careful assembly. For this we get a durable, effective terrace and one that you can walk barefoot on even colder days.

Bangkirai, cumaru, badi, ipe, Karelian pine, Siberian larch, spruce, oak – these are just some species of wood that tolerate harsh conditions on the terrace well, without the need for prior and serious protective measures. However, because they will be outside and will be exposed to sunlight, moisture, snow, variable temperatures – it is worth protecting them, for example, cover them with oil (without this treatment they will gray out over time).

Deck – preparation

The wooden terrace can be built on a hardened earth structure, or placed on concrete posts and joists, to which boards or panels are attached. To make a hardened ground terrace with a wooden surface, start by making the right foundation, which also has a drainage function.

Construction should begin with the excavation of a predetermined shape (increasingly moving away from symmetrical terraces, putting on irregular forms that blur the boundaries between the house and the garden) and a depth of about 40 cm, in which first you need to lay a 15-cm layer of gravel, and then a 10 cm layer of sand.

How to lay terrace boards

When you analyze the construction of the terrace step by step, you need to devote the most attention to the arrangement of the boards. The final effect, durability and efficiency of your work depends on it. You can buy ready, properly cut boards and balustrade elements. If you want to do everything yourself, use a saw to cut successive elements and arrange, starting from home, going to the opposite side.

Fasten each board with screws or nails. Pay attention to the optical effect you want to get. If the terrace is to look long, arrange the boards perpendicular to the house. Do not forget about expansion joints, which allow the wood to work and avoid problems with further operation. 

After installing the wooden terrace

The terrace boards must be thoroughly washed with a mild leaching agent and rinsed with a pressure washer. If we want to protect them against patination, after drying, apply the appropriate impregnate, and then oil. You can opt for an oil preparation containing coloring additives and thus unify the color of the wood. Regular care treatments determine whether the terrace will be beautiful after a few years. The simplest and most important of them – sprinkling boards with water – must be carried out on warm, sunny days. Twice a year, thorough care is needed. The terrace should be washed with a pressure washer, and then apply oil.
