A simple step-by-step guide to integrate LaView WiFi cameras into Home Assistant using the ONVIF protocol. This also works for exposing cameras to Apple HomeKit through Home Assistant.
LaView cameras can be tricky to integrate with Home Assistant because they use non-standard ports and the automatic discovery often fails. This guide shows you exactly what settings to use.
I have a Gmail account that I use primarily for giving out to businesses for promotions, rewards, etc. I don't really pay too much attention to this mailbox and it mostly collects spam. I'm obsessive about having everything "read" in my inboxes, so I wrote this script to mark all messages as read.
The script uses the following steps:
| # author: Alex Stout | |
| # check if the provided argument is a directory | |
| if [[ -d $1 ]]; then | |
| : # nop -- do nothing | |
| elif [[ -f $1 ]]; then # or is it a file | |
| : # nop -- do nothing | |
| else | |
| echo "argument is invalid" | |
| exit 1 |

Hi student,
No sweat. You're so close! It looks like you're not using flexbox which is definitely the recommended way to layout and center content. I'm going to give you a couple pieces because you're pretty much there. First, notice your pricing element is overflowing. This is because you're unnecessarily providing width: 100%, let's let the defaults handle the width here and remove that, width: 100%pricing to fill its parent without regard for the width of its own child content. Next, let's use flexbox by adding display: flex to your pricing element.
And voilà ! That should render your .pricing-tiers within the .pricing element. Does this look how it should? Definitely play around a bit with flexbox and let me know if you have anymore questions!
Hi student,
Welcome to one of modern web development's most polarizing debates!
According to Facebook, React is a JavaScript library. One way to think of a library is that a library is something that provides an interface to make your top-level design simpler and cleaner. I hope you are familiar with the design concept MVC (Model, View, Controller), if not, I enjoy this simple explanation from the perspective of web development.
Hi student,
SQL Injection is definitely a security flaw you'll always want to keep in mind when writing web applications that use SQL databases. SQL injection occurs when SQL queries are performed using standard string interpolation. Any language that supports SQL should also provide SQL libraries that provide methods to safely construct and execute SQL queries using some type of parameter sanitation method or parameter binding.
First, I'll show some examples of SQL injection in practice.
Hi student,
First, I'm glad to hear you're making progress learning Rails ActiveRecord associations. Second, before you consider yourself stuck, I would always recommend seeking out code documentation. Most good modern software has helpful documentation that should be able to steer you in the right direction. The Rails documentation has a great example on has_many :through associations. Let's use their example.
has_many tells ActiveRecord that we want each instance of this model to have associations to one or more instances of another model. Now imagine we want to simply access data of a third model that is referenced only by association of our referenced model from our first model (sorry that was a mouthful). This is where :through comes into play. Consider the following:
class Physician < ApplicationRecord
