There are many different stories of how the band came to the name Pearl Jam, and it's primarily a myth of their own creating. (This is also why the first Pearl Jam album is named Ten, which is honoring Mookie Blaylock's jersey number.) However, Blaylock signed his deal with Epic Records, so the band was forced to take a new name, eventually settling on Pearl Jam after a brainstorm session. Yes, Pearl Jam was originally named Mookie Blaylock. The band Pearl Jam originally named itself after which NBA basketball player? Well, the answer to that is Mookie Blaylock.

While it's true that crop diversity needs to be rescued and protected, as irreplaceable diversity is being lost at an alarming scale, relying solely on burying seeds in freezers is no answer. However, this " ultimate safety net" for the biodiversity that world farming depends on is sadly just the latest move in a wider strategy to make ex situ (off site) storage in seed banks the dominant – indeed, only – approach to crop diversity conservation. The idea is that if some major disaster hits world agriculture, such as fallout from a nuclear war, countries could turn to the Vault to pull out seeds to restart food production. Nestled inside a mountain, the Vault is basically a giant icebox able to hold 4.5 million seed samples in cold storage for humanity's future needs. ![]() Amongst the seeds being protected this way by The Crop Trust currently are 200,000 varieties of rice and 125,000 varieties of wheat.Update: please see our clarification and further discussion at the end of the articleĪfter months of extraordinary publicity, and with the apparently unanimous support of the international scientific community, the "Global Seed Vault" was officially opened today on an island in Svalbard, Norway. They can then request to withdraw the seeds – also for free – if and when they need them. The Svalbard Global Seed Vault in Norway acts as an insurer to other seed collections: this free global service allows organizations to store their seeds once they are already placed in both their own collections and another seed bank, as a final back up. Indeed, the way humans farm and the way cities and industries have grown has damaged the diversity of crops, reducing options for future crops. It exists, in the words of its executive director Åslaug Haga, to “safeguard one of the most important natural resources” – plants. Safely burrowed into the mountain rock, deep enough to protect it from air temperature rihigh enough to avoid potential sea level rises, the Vault, which opened in 2008, is designed to last a thousand years, and to withstand a wide range of potential doomsday scenarios, including climate change, nuclear war, and even an asteroid strike. Nestled into the rocky waste of Plataberget Mountain, amongst the snow, Svalbard is the seed bank of seed banks, designed as a back-up for others. Svalbard Global Seed Vault is located on a remote Norwegian archipelago for seeds to be stored deep within the permafrost. ![]() ![]() In May 2016, Magnum’s Jonas Bendiksen witnessed the deposit of more than 8,000 varieties of crops – from sheep food to chilli peppers – from Germany, Thailand, New Zealand, and the World Vegetable Center into the Svalbard Global Seed Vault, which only opens 2-3 times a year. ![]() ![]() ![]() ![]() Besides this, the columns schemaname and tableowner contain the table that belongs to which schema type and who owns this table. For example, in our table, the column hastriggers have the value f, which means that the current table educba does not define any triggers. Most of the fields’ answers have the values t and f, which are boolean type parameters specifying whether the table has that property or not. The pg_tables table displays the table name and many properties related to the table, which includes schemaname, tableowner, tablespace, hasindexes, hasrules, hastriggers and rowsecurity. We can only expect to retrieve the user-defined table “educba,” which we created. The output of the above query will be as shown below. ![]() WHERE schemaname != 'information_schema' AND We should arrange our query in the following manner: SELECT * FROM pg_catalog.pg_tables For this, we will have to apply the constraint in the WHERE clause specifying that the tables should not belong to pg_catalog or information_schema schemas, as these two schemas only have internal system tables in them. What if we only want to retrieve user-defined tables, not system tables. It will be a long list displaying all the tables that are system tables and user-defined tables. The above query will produce an output similar to the one shown below. When querying a table located in a different database or schema than the one we are currently connected to, we need to explicitly specify the schema name followed by a dot (.) and the table name to retrieve the list of tables. All table information is stored in the pg_tables table of the pg_catalog schema. Now we will learn how we can use the simple SQL query of SELECT to retrieve information about all the tables present in our current database. So we can see now that our table has been added successfully. We can check if the table was added by entering the command: \dt or \dtables Let’s create a new table and check if we can retrieve it. Since there are no tables present in our newly created database, the system is stating that it did not find any relations. Metacommand to list out the user-created or user-defined tables. Metacommands are short commands that are compact and easy to use for database administrators as the psql evaluates this and converts it to SQL queries if required and stored in system tables. Now we will learn how to list the tables using psql metacommands. Listing Out Tables using psql metacommands Now, fire command \c educational_platform Now to switch between databases and use the database of your choice, you can use the command \c or \connect and the name of the database to which you want to connect. Let’s verify if our database has been created by entering the \l command. For this, we will fire the following command. For example, let us create a database named educational_platform. You can use the command createdb and the database name to create a new database. The default databases are Postgres, template0, and template1, while I created the demo database previously. It will list out all the schemas and databases, and the output will be like this. The command to list all databases and schemas. The next step is to check all the databases present in your current database server. The output will be somewhat like the one shown below. Then open the psql shell by typing the command psqlĪnd then click on enter. Other than the system tables, we can create many user-defined tables for our usage. ![]() Furthermore, the system tables maintain information about which tables are currently locked for updation if any retrieval query is executed on that table. In addition, the system tables also store data about SQL and strategic parameters that determine how the system executes any operation and considers primary constraints while executing any command. In this PostgreSQL List Tablesarticle, you will learn various methods that you can use to retrieve and list out the tables present in your database. The database uses these tables internally to perform operations and store system variables, operators, and functions. When creating a new database, PostgreSQL automatically generates default tables known as system tables. This gives us a general idea of the entities stored in the database. When working with a database, it is common to retrieve information about the tables and their structure. ![]() ![]() ![]() ![]() ![]() How To Extend WiFi Signal in Your OfficeĬommercial WiFi and residential WiFi are two very different things and should be treated as such. The equipments’ radio signals can interfere with one another, rendering roaming around the house and maintaining a strong WiFi signal impossible. Unless all equipment is handled by a controller or unified management system, you’ll basically be creating new wireless networks wherever you place the additional equipment. The devices will stay connected to the upstairs router or repeater and the kids will either have to change their network with every floor or complain to you that the WiFi isn’t working right again. The problem comes when your kids leave their rooms and take their devices downstairs. The kids can now use WiFi in their rooms without issue. You install a wireless repeater close to your kids’ bedrooms with the hopes of extending your WiFi range. Your kids are the biggest WiFi users in your house and are constantly complaining about weak WiFi signals and dropped connections. Your kids’ rooms are located on the opposite side of the house, on the top floor. Although a repeater may get the job done, it won’t be a job well done.Ĭonsider this familiar scenario: You have a 2 story house with your Internet connection and wireless router in one corner of the bottom floor. This will definitely extend the wireless signal. We’ve seen people try to solve the issue of extending their WiFi range by installing additional wireless routers or using signal repeaters. Learn about nuances of wireless access point installation from our experts. It may take some trial, error and aesthetic compromise, but by the time you’re through with this post, you’ll know how to arrange your equipment around the unique layout of your home or office. Unless your home is in the construction phase and cables can be hidden in the walls, you’ll usually be left with some amount of visible cable. Running cable is tedious and requires some craftiness. People place their wireless routers in discreet locations for a reason-they’re ugly! It’s true, most wireless routers meant for home use look like something out of a science fiction movie with blinking lights and large antennas.Įven so-called “wireless” routers and APs typically call for at least one cable in order to provide power and Internet connectivity. Your AP’s optimal position may also conflict with your aesthetic. Large structures, like walls and shelving units, as well as materials, such as glass, metal and stone will weaken your wireless signal. However, in most scenarios, a variety of factors prevent a simple repositioning from being the quick fix, especially if you are trying to extend your WiFi signal to an outdoor location, such as the garage or backyard. A centralized location allows the WiFi signal to extend and permeate every square inch of your home equally. In a perfect world, you would position your AP in the exact center of your home. There are sectorized APs that broadcast wireless signals in a 45 or 90 degree area, but you typically don’t find these used outside of commercial applications. ![]() Most wireless routers or APs broadcast wireless signals omnidirectionally, a fancy way of saying the WiFi signal is broadcast in all directions. One of the key elements of a strong WiFi signal is the location of your wireless router or access point (AP). Choose the right location for your router or access point How To Extend WiFi Range Outside (In Your Home) 1. We’ve listed a few situations below, some do’s and don’ts and a summary of them all to help you make a more educated decision when it comes to extending your WiFi signal. Your options vary based on the type of environment you’re in, the type of equipment you’re using and the results that you want to achieve. There are plenty of ways to extend WiFi range outside, from floor to floor, or from building to building, without having to make hefty investments or become a certified network engineer. Wondering how to extend wifi range outside? Think you have to be a network engineer? Think again! You don’t think of your WiFi connection when it’s working properly, but when it isn’t, the slow speeds, dropped connections and dead zones can drive you to obsession, willing to do anything and pay any price to extend your WiFi and have it work properly. Choose the right location for your router or access point. ![]() |
