It is one of the most widely circulated and respected currencies in the world. dollar if you hear the word “dollar” in any conversation. In this post we’ll be highlighting the countries that use dollars, taking a look at currencies pegged to the dollar and exploring how the dollar functions as a worldwide currency. On any exchange rate board right next to the British Pound, the Euro, the Japanese Yen and the Indian Rupee, you are likely to see the instantly recognizable US dollar symbol ($).īut how is the dollar used outside of the United States? How many countries have a currency that is named after the dollar? And what does it mean to have your currency pegged to the U.S. ![]() dollar is one of the strongest and most significant currencies in the world. After you’ve performed basic calibration, the survey begins. The app can take any two measurements and calibrate the rest of the floorplan based on those distances, provided the floorplan you use is to scale.Īfter this, NetSpot asks if you want it to scan any other Wi-Fi networks. You can calibrate your map by selecting two points and entering the actual distance between them. You can also upload a floorplan of your office or apartment (if one is available) and work off that. ![]() ![]() You can design a map of your space by drawing it, choosing a sample map, or starting with a completely blank map. ![]()
![]() There are a few ways to use it, as it happens.īut, in any case, you’ll first need to navigate to Google Images and select the camera symbol from the search results. It can also help confirm or fact-check a particular image used in a news report, meme, etc. This function is most useful for specific users for various reasons.įor example, you can use it to check for the original owner of an image to verify or check for any potential copyright issues using it. ![]() More accurately called 'Google Images' or 'Google Search by Images', the function had existed since 2011 when the internet giant began to offer it. There are a few products out there you can use to perform this sort of search, but Google’s reverse image function is one of the most popular. This means that a user doesn't have to guess at keywords or terms that might or might not bring up the right results.Ī reverse image search lets users find content related to a specific sample image, find out how popular an image is, and find altered versions of the image and works based on it. In particular, reverse image search is defined by the fact that it doesn't have any search terms. More technically, a reverse image search is a content-based image retrieval (CBIR) query method that gives the CBIR system a sample image it will use to base its search. What is a reverse image search?Īs the name suggests, a reverse image search is a technique for querying the internet for an image to see if any other exact examples are present. But there is another way, something called reverse image searches.īut what is it? And how do you do that? Let's find out. ![]() So, how do you navigate this minefield safely? One option is using images in the public domain, but you are often stuck with low-quality or irrelevant images. Even using "copyright-free" images from sites like Flickr isn't always foolproof, as creators can claim other people's work as their own. ![]() While that sounds obvious enough, unless you know the original creator and have their permission to use it, you could be exposing yourself to potential copyright claims in the future. ![]() Because of the need for more efficiency, digital technology gets more widespread, and new technologies in the energy grid heavily rely on high-frequency monitoring cycles and adaptation to bottlenecks in the grid. ![]() This is also reflected by a legislative point of view, with power grids being classified as critical infrastructure in many countries. Despite its importance to modern society, the energy sector has adapted slower than other industries to digital technology due to its size and need for high system availability. Historically, power grids have grown from simple, localized grids to large, physically wide-spread grids, often spanning multiple nations or even whole continents. For each of these categories, we distill and discuss a comprehensive set of state-of-the art approaches, as well as identify further opportunities to strengthen cybersecurity in interconnected power grids. To address these challenges, we propose to rely on a defense-in-depth strategy, which encompasses measures for (i) device and application security, (ii) network security, and (iii) physical security, as well as (iv) policies, procedures, and awareness. Based on these challenges, we identify a broad set of resulting attack vectors and attack scenarios that threaten the security of power grids. ![]() In this paper, we analyze the communication infrastructure of power grids to derive resulting fundamental challenges of power grids with respect to cybersecurity. Indeed, cyber attacks on power grids have already succeeded in causing temporary, large-scale blackouts in the recent past. ![]() The resulting increase in communication creates a larger attack surface for malicious actors. Increasing volatilities within power transmission and distribution force power grid operators to amplify their use of communication infrastructure to monitor and control their grid. ![]() ![]() ![]() Once we are sure of the version of Node.js that we want to uninstall, we can execute the command below. The command below lists all the versions of Node.js that are currently installed in your system $ nvm list If you’re running multiple versions of Node.js, we also need to verify the exact version that we want to uninstall from our system. Begin by running the command below to remove /.nvm/*/bin from $PATH. $ nvm uninstall Ī more extensive approach to uninstall Node.js, which eventually leads to the same solution, is as follows. If we already know the Node.js version installed in your system, you can uninstall Node.js by specifying the version number below. Besides allowing us to also switch between multiple versions, we can remove pre-existing installations of Node.js. The Node Version Manager is another helpful package for managing multiple versions on UNIX-like systems, macOS included. This game is fully loaded with challenging features.
