PHP, MYSGL The company "Visitors" wants a website for a guestbook. They want the guestbook to work so that you can create and delete posts in it.The guestbook must contain the entries who made the post (name or alias),The post (the text written) anddate and time when the post took place.The created posts must be stored in a text file in serialized form.NOTE! You do not need to be able to update these posts, it is enough that you can create new ones and delete any post. Your solution should be object-oriented with PHP and be able to store / read all information against a serialized file on your server.The features to be implemented in your solution on the guestbook website should be: possibility to create and delete posts in the guestbookInformation that should be in each record should be:username / signature, post, date + time of created postExamples of entries in the file:The silver surfer, In the sea are the biggest fish, 2018-01-17 22:41:55Falo, 100 small mice built a nest in a…

Lab 02: Splitting a URL into pieces URLS are composed of five pieces: The scheme, also known as the protocol The authority (may further be divided into the user info, the host, and the port) The path The fragment identifier, also known as the section or ref The query string Read-only access to these parts of a URL is provided by nine public methods: getFile(), getHost(), getPort(), getProtocol(), getRef(), getQuery(), getPath(), getUserinfo(), and getAuthority(). Write a Java program which uses these methods to split URLS entered on the command line into their component parts.

Linux bin bash script to create a new user on your Linux system and assign the user to a group. The script will first check if the user and group exists. If the user exists, provide a message saying the user exists. If the user doesn’t exist, create the group, if it doesn’t exist, and then create the user, finally assign the user to the group. Move the script to /home//scripts/ directory. Change the group to techstaff. Set appropriate permissions.

The Node class has three fields: • a double data value, • a reference to the next node, and • a reference to the previous node. Each field is protected. So code outside of the class must use the provided getter and setter methods to get or set a field. Node.java is read only, since no changes are required.

Bitcoin script: Alice is on a kayaking trip and is worried that her phone (which contains her private key) might fall overboard. She would like to store her bitcoins in such a way that they can be spent with knowledge of a password. Accordingly, she stores them in the following ScriptPubKey address: OP_SHA1 <0x13818a5684a7ed4dce8433c3f57e13b589b88852> OP_EQUALVERIFY Write a ScriptSig script that will successfully redeem this transaction.
