How to do calculations on Command Prompt ?
The command processor CMD.EXE comes with a mini calculator that can perform simple arithematic operations:
C:\>SET /A 5+3
8
C:\>SET /A 3*(9/4)
6
C:\>SET /A (4*5)/5
4

How to Create your own Run Command ?
Step 1: Go to “Start,” “Run,” (told you we use it a lot) and type regedit.

Step 2: Navigate to the following:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Apps Path

Step 3: Create a new folder/key under Apps Path. (Right-Click Apps Path and click “New,” “Key.”)

Step 4: Title the new folder/key the name of the application, e.g. firefox.exe.

Step 5: Right-Click the default string value (the thing automatically created in your new folder) and click Modify.

Step 6: Change the value to the path of the executable you are attempting to run. E.g. C:\Program Files\Mozilla Firefox\firefox.exe.

Step 7: Create a new “String Value” by right-clicking under the default value (the thing we just edited) and select “New,” “String Value.” Name it Path and enter the value as the same path you previously entered.

Reasons not to buy Akaso action camera if you are from india

By
Recently I made a full review of the action camera I brought after doing a ton of research and time. Having used it for a couple of months I feel extremely glad that it meets up to my expectations. But recently, I accidentally tipped off the camera without an external case and it cracked my lens. This, in turn, added a shady spot on my phone or video and I cannot use that anymore (Some phones of the cracked lens below)     I immediately mailed the akaso team to ask if there is anything they could do but unfortunately, this was their response. Oops, that was not what I was expecting and then I asked them I could get any details of the replacement parts or anything like that so that I can order it online. But that didn't happen it took a lot of time for them to respond me back(I have been bugging them on Facebook and email).  But after some time they left me with this response which I had no other choice but to accept. After getting the 50%re...

THM — RUST — [task 13] challenge - writeup

By
Before starting this you must get familiar with all the previous tasks and run some code in the tasks and get familiar with error handling and using crates. If you have difficulty completing the previous tasks here is a walkthrough video of them. TryHackMe — learn Rust — [Task 13] : So as given the string is already encrypted and all you have to do is to decrypt in the order of rot13 -> base64 -> ROT13 -> plaintext and find the flag. To do that you can head to https://crates.io/ to find external packages which will decrypt the text for you out of the box, so search for packages such as base64 and rot13 to make use of them to use them in our code. So here are some packages which I used cipher-crypt = “0.17.0” base64 = “0.12.3” will use cipher-crypt for rot13 and base64 for base 64 decryption. So now you can add them to your dependencies in Cargo.toml file(as below) Now you are all set to use the packages it in your code. Then you can import these packages in your code as be...
