Find the Missing Number | CS interview question | Gauss Sum Method
Computer science job interview question: Find the missing number in the series. Write a program to calculate the missing number in the series of integers. Using the Gauss Sum addition method is a nice trick and it's faster than any brute-force iteration you might think of. More info https://en.wikipedia.org/wiki/Gauss_sum
The idea is that you take the count of elements you have including the missing number and add 1 to that then divide it by 2. This is a nice way to write some leetcode or leet-code 1337 and pretend you know what you're doing. https://en.wikipedia.org/wiki/Leet
n*(n+1)/2
In the video you will see why you need to add the +1 there and why this works.

The boot parcel shelf string is broken at the anchor points where it ties the parcel sgelf to the rear door and lifts the boot shelf when the boot door opens.
With the anchor hooks broken on the parcel boot shelf, the shelf doesn't lift when opening the read boot door.
Fortunately if you have the pieces, you can glue them back as seen in the video with Super Glue gel or with 2 part epoxy.
Super glue is fast and easy to install but epoxy needs 24h to 48h of no load and tape on top to keep the part in place.
I used both in the past as you see in the video but super glue is much easier.
Until next time it breaks.

Victorinox MiniChamp Alox Swiss Army Knife Functions and close look unboxing of the silver alox Mini Champ sak.
Great for edc and can be used on the keychain easily even though it has all the Mini SAK tools, it doesn't have the scales tools such as, pen, tweezers, toothpick, light.
It's biggest plus is that even being a Mini Champ Alox packed with all the tools you might need, it's still thin and feels more solid compared to Cellidor plastic scales sak models.

In the box:
HDD
USB 3.0 data cable
Power supply and socket adapters
Manual, warranty, etc...
For the drive to spin-up you must connect power and the data cable. If only power is connected, it will stay in sleep mode.
During a transfer speed test the drive just stopped working and an error message popped up about a transfer error the drive disappeared from the drives list in my computer.
Checked the windows event log and that confirmed, the drive disappeared on it's own and the event log had errors related to the HDD.
After a bit of troubleshooting I've realized what was the problem. Specifically the problem was USB 3.0. Showing how to resolve the transfer errors in the video.
