Summary - Unreasonable Hospitality

Unreasonable Hospitality by Will Guidara

Unreasonable hospitality and its effects on your business

Unreasonable. This word has long screamed negativity, whether it’s your kid insisting on buying an expensive toy, a coworker who doesn’t compromise for the good of the project, or your mom refusing to listen to your sentiments. But what if you learn that being unreasonable could actually be a good thing?

In the service industry, hospitality is all about making people feel cared for, but when you add "unreasonable" to the mix, it takes things to a whole new level. Unreasonable hospitality is all about providing your customers with a unique, tailor-made service that makes them feel not just cared for but like real VIPs.

It’s not just about meeting expectations, it’s about exceeding them. And this act of going above and beyond creates an unforgettable encounter that’ll linger in people’s memories long after the experience is over.

Tinkercad meshes are limited to 300,000 triangles

File too large. Tinkercad limits imported files to 25MB.

This shape's mesh is too complex. Tinkercad meshes are limited to 300,000 triangles.  Try simplifying the mesh before re-importing it.

Sometimes a STL file has too much detail for Tinkercad.  If you just want to view what is in the file you can try gmsh.

Data Breach Reports

Verizon Data Breach Investigations Report (DBIR).

 

  • Verizon Data Breach Investigations Report 2022

    The DBIR was created to provide a place for security practitioners to look for data-driven, real-world views on what commonly befalls companies with regard to cybercrime. 

    The past year has been extraordinary in a number of ways, but it was certainly memorable with regard to the murky world of cybercrime. From very well publicized critical infrastructure attacks to massive supply chain breaches, the financially motivated criminals and nefarious nation-state actors have rarely, if ever, come out swinging the way they did over the last 12 months. As always, we will examine what our data has to tell us about these and the other common action types used against enterprises. This year the DBIR team analyzed 23,896 security incidents, of which, 5,212 were confirmed data breaches.

Password Cracking

The Length of a Password is More Important than the Complexity

password length

As you can see above adding 4 characters to a password length with no special characters makes the password much more secure than requiring adding special characters like uppercase, lowercase, digits and symbols with the same length.

 

  • A good password

    passwordPasswords are (one of) the biggest pain(s) in today’s IT security. They are a factor of life, and the modern lifestyle requires us to have a great many of them. So we need to make sure we’re aware of what is a strong and a secure password. How many times did we enter our information into an online service, registering with our credentials, only to be greeted with a variation of a “Please use a strong password” message?

Using CURL to test website response time.

Detailed timing of a website response

The following command returns lookup, connect, pretransfer, starttransfer time in seconds and the total time that the full operation lasted.

$ curl -s -w '\nLookup time:\t%{time_namelookup}\nConnect time:\t%{time_connect}\nPreXfer time:\t%{time_pretransfer}\nStartXfer time:\t%{time_starttransfer}\n\nTotal time:\t%{time_total}\n' -o /dev/null http://www.shellhacks.com

Sample output:

Lookup time:    0,004
Connect time:   0,022
PreXfer time:   0,022
StartXfer time: 0,068

Total time:     0,125

How to convert media files - Rip DVDs

To convert DVD movies to play on Plex, Android or Iphone devices.

I only use these tools to rip DVD for my personal use, some DVDs are copyrighted in a way that ripping them is illegal even for personal use. 

Update - New Way use MakeMKV instead of DVDDecrypter: current registration key

I now use MakeMKV to extract files from DVDs or Blu-Ray, then I use the current version of Handbrake to compress to .mp4 files. 

Insert your DVD and click on the DVD drive image

It will scan the drive to find titles

MakeMKV process

Select the movie, usually the first large file, update the output folder and click MakeMKV button. 

MakeMKV save

Then continue with Handbrake as below.
