These devices don’t exactly come cheap, however, so expect to spend at least a few hundred dollars to get something worth your while. Gimbals use motors to counteract momvement, producing incredibly smooth footage in virtually any setting, from an easy handheld shot to an epic downhill mountain bike ride. This will let you make smooth pans to follow a subject or reveal a landscape.įor stabilizing shots in motion, there’s nothing better than a powered gimbal. As a GoPro is very light weight, there’s no need to get a heavy duty set of sticks for it, but do consider a tripod with a fluid pan head. For stationary shots, nothing beats a good-old tripod when it comes to stability. One of the best things about GoPro cameras being as ubiquitous as they are is that third-party accessories are equally common. The Hero7 Black features revolutionary electronic image stabilization, but as impressive as it is, using an external stabilizer still has its benefits, whether you need a static shot or a moving one. These filters are often found in sets, and the one you should use depends on they type of water and how deep you’ll be diving in it. Essentially sunglasses for your camera, an ND filter simply limits the light passing through to the lens.Ī polarizing filter is useful for cutting out reflections on glass or water, and can help your GoPro see through the surface of a lake or the windshield of a car.Īnd if you actually want to film underwater, a red or magenta filter will help remove the blue-green colorcast inherent to that environment. A host of GoPro filters are available to choose from, like this collection from Polarpro, but there are a few types worth drawing attention to.Ī neutral density (ND) filter works wonders when filming in bright environments by allowing for a slower shutter speed, which keeps footage looking smooth and natural. We aren’t talking about Instagram-like retro color filters or any other digital effect - we’re talking about actual physical filters that you can place in front of the lens to alter the light your GoPro sees. Image used with permission by copyright holder The narrower fields of view are good when you have more control over your framing and want to hone in on a particular subject or area of the scene. Here’s an easy way to remember which field of view you should pick: If you’re unsure of your framing and want to know that you’re getting all the action, go for ultra-wide. ![]() And don’t forget - you can even mount your GoPro upside down and it will automatically flip the footage to display it the right way. Making use of different fields of view is another way to mix up your shots. The Hero6 Black and new Hero7 Black even have touch-to-zoom functions that mimic a traditional zoom lens. Newer GoPro cameras offer a selection of crop modes, such as an ultrawide 170-degree angle of view, a medium 127 degrees, and a narrow 79 degrees. Even if you have just a single camera, if you’re going to be repeating an action many times throughout the day - say for surfing or snowboarding - consider repositioning the camera on each run to capture a greater variety of shots that can be edited together later. For example, when recording action, it’s most common to mount a forward-facing GoPro, but sometimes looking back at yourself can produce equally entertaining footage. ![]() We also recommend trying a mix of different camera positions to give viewers a comprehensive view of what’s going on, rather than just sticking to one viewpoint. As mountain bike YouTube channel the Loam Ranger explains, a GoPro strapped to your chest can lead to much more dramatic footage than one mounted way up on your helmet, as it puts your perspective closer to the ground. To illustrate a sense of speed, placing a GoPro closer to the action can really help. ![]() A GoPro offers a very wide angle of view that makes it easy to capture the action, but to create truly interesting videos, you should do more than simply set it and forget it.

Pg-dumpall generates a single script file with SQL commands that can be entered into psql to restore PostgreSQL databases. Only one database at a time is dumped by pg-dump, and neither roles nor tablespaces information is included. ![]() Pg-dump is a utility for backing up a PostgreSQL database even when the database is being used simultaneously and it doesn’t prevent other users from accessing the database. ![]() Generally, there are several PostgreSQL tools for database backup and recovery: pg_dump /pg_dumpall and plsql, pg_restore. How do you backup and restore the PostgreSQL database? We can migrate Oracle DB, MySQL, and SQL Server to PostgreSQL and vice versa. Long-term benefits: The initial investment in database backup may seem costly, but it produces long-term benefits, for instance, backup saves time, money, and energy trying to retrieve lost data.ĭata research: Saved data could be used to research on market and customers, generate annual audits or reports, and plan for the business's future.ĭatabase migration: Sometimes, we just need to backup and export data for migration. Additionally, as the basis and source of disaster recovery, database backup brings peace of mind facing data loss.īusiness continuity: Being the intangible core asset of a company, frequent database backup ensures data availability and therefore, business continuity. Too many reasons to list here that necessitate database backups for later data recovery.ĭata loss prevention: Having regular database backups minimizes data loss in the event of ransomware attacks, system failures, or other disasters.ĭisaster recovery: Backup is the safest, simplest, and most reliable way to restore lost data after disasters. We all know those database backups are the bottom line and safety net for data loss prevention and disaster recovery in case of any mishap, but not all of us really understand the necessity and stick to the business continuity plan based on backups. With it, you can establish the data types, customize your functions, control the metadata, and write code in a different programming language (Perl, Tcl, and Python) without having to recompile the database. ![]() Working with a number of technologies such as Multi-Version Concurrency Control, hot backups, point-in-time recovery, asynchronous replication, query planner, fault tolerance, etc., PostgreSQL differentiates it with extensibility and compliance from others. Data points are kept in rows with columns acting as various data properties. The database runs on multiple widely used operating systems like Linux, Windows, Mac OS, FreeBSD, and OpenBSD. PostgreSQL, or Postgres, is an extensible open-source relational database management system (RDBMS) that supports SQL and JSON querying. But before that, let me take you through what is PostgreSQL and find out why it is used so extensively. Also, you’ll get the hang of their uses, and another easier substitute available is provided afterwards. In this article, you’ll learn various PostgreSQL backup and restore techniques with built-in tools and why you need to do so. Database backups, which copy data from a database and store them elsewhere for data retrieval in event of cyberattacks, human errors, and accidents, are one of the methods databases keep the data safe and business in operation.

This sound experiment is an easy way to show kids that sound causes vibrations/movement. ![]() When the fork is touched to the water it makes the water splash out of the bowl. Make sure to only touch the water, and not the container. Repeat the experiment above by banging the tuning fork and then touch it to the container with water. I also added a few drops of food coloring just for fun. If you have all of the materials for the fork a sound experiment, all you need extra to do another experiment is water!Īs an extension, you can remove the plastic wrap and fill the glass bowls with water. The tuning fork experiment sparked so much interest in my classroom that I wanted to extend our activity for another science lesson. ![]() We added a few small pompoms on top to test if the vibrations could still make the extra weight of the pompom bounce. Once they have guessed, they are ready to do the experiment. They make a guess what will happen once they touch the tuning fork to the plastic wrap. The rice will go flying!!! (But that’s also the fun of the experiment.)Ĭhildren then pour the rice onto the plastic wrap. You only need a small amount for each group.Īlso, the more rice you give each group the more clean up there will be. I then gave each group a small container of rice. Each group got a container with the plastic wrap stretched across it. Next, children went to the tables with a small group. Also make sure they are not banging it on anything that could break.) (I would suggest making sure to tell children not to hit the tuning forks too hard. When it stopped vibrating, the sound also stopped.Ĭhildren then each had a chance to gently try out the tuning forks. We talked about the fact that when it was vibrating, it was making a sound. They were able to feel that it was vibrating, but as soon as they touched the tuning fork the vibrations stopped. I had a child beside me gently touch the fork. We could hear a bit of a sound coming from the fork. ![]() I gently banged one of the forks onto the carpet and held it up. Some recognized the fork being used in their music class before. To start, I introduced the children to tuning forks. ![]() The wrap has to be tight or the experiment will not work. The smaller the groups the better.Ĭover each container tightly with plastic wrap. Since I did this experiment with several groups, I had several containers ready to go. Uncooked rice or Large Sparkles (I added some food coloring to mine, but the color is just for fun.).Also, kids of all ages are able to get hands-on and do the experiment. This is perhaps my favorite sound experiment for kids! I love the excitement that it causes and the ‘explosive’ result. This was a great chance to discuss echoes and how sound bounces. Some students even noticed the slinky bounce back after reaching the student holding the other end of the slinky. The slinky is just a fun way to show what we can’t otherwise see. Also, it is important that children know that sound waves are invisible. The main idea you want to make clear is that sound travels in waves.

Over the course of the year of content for Lightfall includes one new raid, "Root of Nightmares", released on March 10, 2023, two new dungeons, and one returning raid, "Crota's End", from the original Destiny's (2014) The Dark Below expansion, which was added on September 1, 2023, during Season 22 and is free for all players to access. Lightfall expands on the base Destiny 2 gameplay by adding a new free roam world for the city Neomuna on the planet Neptune. There are also four seasonal content offerings to be released throughout Year 6 of the game: Season of Defiance, which was available alongside the expansion, Season of the Deep in May 2023, Season of the Witch, the current season that began on August 22, 2023, and one more unnamed season to be released in November 2023. Two new dungeons as well as a returning reprised raid from either the original Destiny or one previously removed from Destiny 2 will be released over the course of the year. ![]() ![]() The expansion added new content across the game, including new missions, Player versus Environment locations, a Player versus Player map, player gear, weaponry, and a new raid. Lightfall revolves around the exiled Cabal emperor Calus, a recurring character throughout Destiny 2, now a Disciple of the Witness, as he, the Witness, and their army of Shadow Legion Cabal and Tormentors attack the secret, technologically advanced human city of Neomuna on Neptune to procure a mysterious being called the Veil to herald a second Collapse. ![]() Representing the seventh expansion and the sixth year of extended content for Destiny 2, it was released on February 28, 2023, after being pushed back from its original fall 2022 release as a result of the delay of the previous expansion, The Witch Queen. Action role-playing, first-person shooterĭestiny 2: Lightfall is a major expansion for Destiny 2, a first-person shooter video game by Bungie. It is typical for the quantum energy state of such a valence electron to be split by fine structure arising from the magnetic interaction of the electron spin with the orbital angular momentum of the inner electrons. The next available energy level is the 6s electron, so the chemistry of cesium is determined by that lone 6s electron. ![]() Following the order of filling of the electron shells, the xenon structure fills all the levels up through the 5p electrons. The electron states are described by four quantum numbers, and those of cesium fill all the electron states that are part of the noble gas xenon (54 electrons) and then there is just one additional electron outside that symmetric electron distribution. Having 55 protons in its nucleus, it must have 55 electrons in orbit around that nucleus to be a neutral atom. To understand how remarkable the cesium atom is as a basis for the cesium atomic clock, it is necessary to examine the details of the structure of this atom. Time signals based on it are available by short wave radio (WWV and WWVH). Cesium clocks have demonstrated stability to 2 parts in 10 14, or one second in 1,400,000 years according to the Naval Observatory source cited below. The frequency of this atomic clock is in the microwave region of the electromagnetic spectrum and is a convenient one for locking a microwave oscillator. Prior to 1964 the international standard second had been based upon the orbital period of the Earth, but the cesium clock period was found to be much more stable than the Earth's orbit! The SI unit of time, the second, is now defined by this transition in cesium. In 1967 a standard second was adopted based on the frequency of a transition in the Cs-133 atom:ġ second = 9,192, 631,770 cycles of the standard Cs-133 transition The current time standard for the United States is a cesium atomic frequency standard at the National Institute of Standards and Technology in Boulder, Colorado. Atomic clocks are integral parts of the Global Positioning System since extreme accuracy in timing is necessary for the triangulation involved. Such clocks have provided the accuracy necessary to test general relativity and to track variations in the frequencies of pulsars. ![]() The two most widely used atomic clocks in recent years have been the cesium beam atomic clock and the rubidium clock. The frequencies associated with such transitions are so reproducible that the definition of the second is now tied to the frequency associated with a transition in cesium-133: 1 second = 9,192, 631,770 cycles of the standard Cs-133 transition Very accurate clocks can be constructed by locking an electronic oscillator to the frequency of an atomic transition. If you want to add a new user account, you can easily control everything via the graphical user interface. For that the command syntax will be: sudo deluser userĭelete user including data from the home directory: sudo deluser -remove-home h2smedia Perhaps later you don’t require some user on your Ubuntu Linux system, in such a case we can delete them even the one you have created. However, this is only possible if the user name to be changed is currently not active (i.e. The username can be easily changed using sudo usermod -l new-username old-usernameįor example: sudo usermod -l myh2s h2smedia For that we can go for the given command syntax: sudo deluser user sudo Well, maybe later you want to revoke or remove the sudo access given to the created or from any existing user. sudo adduser user sudoįor example, here we have a user h2smedia and if we want to provide it sudo rights then the command will be: sudo adduser h2smedia sudo Now, if you also want to give sudo rights to your newly created so that it can execute the command with Admin rights then that is also possible. Whereas to list all available users, we can use: cut -d: -f1 /etc/passwdįor only all normal (non-system etc) users: awk -F'' '' /etc/passwd To List all users on Ubuntu 22.04 or 20.04 In case you missed out on the append option and messed up a user's groups, you can still utilize the output you saw in the second step and add the user to all the groups it belonged to previously.Replace the user with the one you have created in the above command.Ĥ. You just have to verify that things went right.Ĭheck the groups of the user and see if it belongs to the desired groups or not. Step 4: Verify that the user has been added to the new group If things go right, you won't see any output. This is not something you would want in most cases. Without the option -a, you'll remove the user from existing groups and add it only to this new group. Since you are adding it to an additional group, you should use the append mode with option -a: sudo usermod -a -G group_name username So, you'll be modifying the user's properties and adding it to an additional group. If it runs successfully, you should see an output like this: adduser abhi adminĪlternatively, you can use the usermod command. Step 3: Add user to the groupįor this, I recommend using the adduser command on Ubuntu: sudo adduser username groupname Now, you have the user name and the group information. If the group doesn't exist, you can create a new group like this: sudo groupadd new_group_name The output is several lines long, by the way. You can see all the groups and get the exact group name from the output. If needed, you can see all the user groups present on your Ubuntu system: getent group That's the Ubuntu way of creating the primary group with the same name as the user name. As you can see the user abhi belongs to the group abhi. Step 2: Get the groups detailsįirst, check the groups the user belongs to: groups username Once you know the user name, it's time to find the details about the group. I'll be changing the group of the user abhi and add it to sudoer list by adding it to the sudo group. Normally, the regular users (non-system users) are at the bottom of the long output of the compgen command: compgen -u ![]() If you are not sure of the exact username, you can list all the users on your Ubuntu system.
