...SE1-2004-lec12.pdf, page 11. This is also true of disk drives, cd drives, etc...
GUIDs are statistically unique and the data you read from the db is only statistically correct.

Why aren't programs written in Assembly more often? [closed]
...ur old code can easily make use of the new instructions.
What if the next CPU has twice as many registers?
The converse of this question would be: What functionality do compilers provide?
I doubt you can/want to/should optimize your ASM better than gcc -O3 can.
...
Why is Swift compile time so slow?
... with high accuracy whether your refactorings (explicit casts, type hints, etc...) are lowering compile times for specific files or not.
NOTE: technically you could also do it with xcodebuild but the output is incredibly verbose and hard to consume.
...
The application may be doing too much work on its main thread
... in a vast array of hardware unlike ios
and windows devices. The RAM and CPU varies and if you want a
reasonable performance and user experience on all the devices then you
need to fix this thing. When frames are skipped the UI is slow and
laggy, which is not a desirable user experience.

Vagrant stuck connection timeout retrying
... startup to select whether I wanted to boot directly to ubuntu or safemode etc.
To turn on the GUI you have to put this in your vagrant config Vagrantfile:

What is the fastest way to send 100,000 HTTP requests in Python?
...and I found this to work the best for me using python3.6.
I was able to fetch about ~150 unique domains per second running on AWS.

Secure hash and salt for PHP passwords
...rcing a password policy of X length with X many letters, numbers, symbols, etc, can actually reduce entropy by making the password scheme more predictable. I do agree. Randomess, as truly random as possible, is always the safest but least memorable solution.
So far as I've been able to tell, making...
Serving gzipped CSS and JavaScript from Amazon CloudFront via S3
...p into your build/deployment scripts. The advantages are:
It requires no CPU for Apache to gzip the content when the file is requested.
The files are gzipped at the highest compression level (assuming gzip -9).
You're serving the file from a CDN.
Assuming that your CSS/JavaScript files are (a) m...
Minimal web server using netcat
I'm trying to set up a minimal web server using netcat (nc). When the browser calls up localhost:1500, for instance, it should show the result of a function ( date in the example below, but eventually it'll be a python or c program that yields some data).
My little netcat web server needs to be a w...
Custom CSS Scrollbar for Firefox
...and has loads of parameters you can tweak, but it ended up being a bit too CPU intensive for me (and it adds a fair amount to the DOM).
Now I'm giving Perfect Scrollbar a go. It's simple and lightweight (6KB) and it's doing a decent job so far. It's not CPU intensive at all (as far as I can tell) a...
