Linux pathname Relative Vs. Absolute

-

Linux directories are helpful to store files. Many a time, the programmer would trade in directory paths. The paths are two types - absolute and relative. I have shared simple ideas to remember the differences between these two.


Absolute vs Relative
Linux

Absolute Vs. Relative

Below are the differences between these two.

Absolute pathname


An example is /usr/lib, which is an exact directory in the directory tree. 


Think of the absolute pathname as being the complete mailing address for a package that the postal service will deliver to your next-door neighbor.

Relative directory name


An example is cups, which represents the cups subdirectory of the current directory, whatever that may be. 


Think of the relative directory name as giving the postal carrier directions from your house to the one next door so that the carrier can deliver the package.

How to go back to the home directory

If I type cd cups in /usr/lib, the current directory changes to /usr/lib/cups. If type the same command in /home/edulaney, the shell tries to change the current directory to /home/edulaney/cups.



If you type cd, without any arguments, it will go to the home directory.

In Python, you can call parsing errors Syntax errors. How to fix the syntax errors quickly, I can show in this post. Also, check Python Syntax Errors Cheat Sheet. Python Syntax Error. If you run the Python code, the interpreter first parses the logic. If any errors found, it is the developer's responsibility to fix them. Courtesy: Python documentation. >>> while True print('Hello world')   File "<stdin>", line 1     while True print('Hello world')                    ^ SyntaxError: invalid syntax How to Fix the Syntax Error First, check for the line number. In the above case, it is '1'. Then look for the symbol '^'. The issue is at the PRINT function. The reason is before the PRINT function you need a colon ':'. That is the reason, you are getting error. This is a syntax error. Find below the corrected logic: >>> while True : print('Hello world')   File "<stdin>", line 1     while Tr

Import 'sys' Library. You need to import the 'sys' library to use the SIZE commands.  >>> import sys Congrats to you since you have now imported the SYS library. The command name is " getsizeof" . Check the below example. print("An Integer:") i = int(100) print(sys.getsizeof(i)) The result will be: 100 What is the size command?  - is to get the size of elements. It gives the result based on the object you are being used. Suppose, if you use Strings, you will get String length. How to use the  'getsizeof' command? Example:1 print("Empty string:") empty_string = "" print(sys.getsizeof(empty_string)) Example:2 print("A normal string") s = "Hello world" print(sys.getsizeof(s)) Example:3 print(&quo

How to Decode TLV Quickly

In TLV, the format is Tag, Length, and Value. The TLV protocol needs this type of data. Here you will know how to decode TLV data.  According to IBM , TLV data is three parts. The tag tells what type of data it is. The length field denotes the length of the value. The Value-field denotes the actual value. Structure of TLV. TLV comprises three field values.  Tag Length Value EMV formulated different tags. They have their meanings. Usually, the Tag and Length together takes 1 to 4 bytes. The Best example for TLV. In the below example, you can find the sample TAG, LENGTH, and VALUE fields. [Tag][Value Length][Value] (ex. " 9F4005F000F0A001 ") where Tag Name =  9F40 Value Length (in bytes) =  05  Value (Hex representation of bytes. Example, "F0" – 1-byte) =  F000F0A001 In the above message, tag 9F40 has some meaning designed by EMV company. Here  you can find a list of EMV Tags. How to read the TLV Tag: 1 or 2 bytes Length: Length of the Value. F0-00-F0-A0-01 ==> 5 B

In AWS, you have three types of load-balancers. In the case of Azure, you have only two load balancers. This post tells you the comparison between these two. AWS Load Balancers: Application Load balancer Network Load balancer Classic Load balancers. Application Load Balancer Balancing of HTTP and HTTPS traffic and provides advanced request routing targeted at the delivery of modern application architectures, including microservices and containers.  Operating at the individual request level (Layer 7), Application Load Balancer routes traffic to targets within Amazon Virtual Private Cloud (Amazon VPC) based on the content of the request. Network Load Balancer Network Load Balancer is best suited for load balancing of Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Transport Layer Security (TLS) traffic where extreme performance is required.

The differences between QlikView Server and publisher, I have given for your reference. These are related to internally how differ each other. QLIKVIEW SERVER The QVS is a server-side product.  It contains an  in-memory analytics engine , which handles all client/server communication between a QlikView client (Desktop, IE plugin, AJAX, or Mobile) and the server. The Administrator can have access to the management console to control all aspects of the server deployments (including security, clustering, distribution, etc.)  It also includes a web server to provide front-end access to the documents within. The web server’s user portal is known as Access Point. (It’s important to note that while the QVS contains its web server, one can utilize Microsoft IIS (Internet Information Server) for this purpose, too). The QVS handles client authorization against existing directory providers (Microsoft Active Directory, eDirectory) It also performs read and write to ACLs (access control lists) for

Top 10 SCALA Quiz Questions for Programmers

Scala is an acronym for “Scalable Language” . This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission-critical systems , as many companies, including Twitter, LinkedIn, or Intel does. To some, Scala feels like a scripting language. Its syntax is a concise and low ceremony; its types get out of the way because the compiler can infer them. There are a REPL and IDE worksheets for quick feedback. Developers like it so much that Scala won the ScriptBowl contest at the 2012 JavaOne conference. At the same time, Scala is the preferred workhorse language for many mission-critical server systems. The generated code is on a par with Java’s and its precise typing means that many problems are caught at compile-time rather than after deployment. ✅ SCALA Quiz Link At the root, the language’s scalability is the result of a careful integration of object-oriented and functional language concepts

Python Syntax Errors Cheat Sheet

In Python, if you know syntax rules, you can eliminate errors. The mistakes programmers do are missing semicolons, adding extra commas, and extra spaces. Further Python is case sensitive. So using the wrong identifier gives an error. Python Syntax Rules List Indentation is unique to Python. You cannot find strict indentation in any other programming language. You need to focus on the three areas while writing a Python program. To avoid errors you need to learn indentation rules. Indentation or Syntax Errors Exceptions Handling Exceptions 1: Indentation If you do not follow the proper order, you will get an error. The details of one block shroud follow in one vertical line. The sub-block should be inside of that. In if loop, the IF, ELIF, and ELSE should have the same indentation. Not only, but the statement inside of them should also have the same indentation. Best Examples Understand these examples a good material on indentation for you. 2: Exceptions Python raises an excepti
