Grayscale:  filter: grayscale(100%);
Solid Gray: filter: contrast(0);
Solid Black:  filter: contrast(0) brightness(0);
Solid White:  filter: contrast(0) brightness(2);

You can adjust the contrast value between 0 and 1 to achieve different levels of darkness.

Easiest Way to Make Good Steak

Posted on Jun 22, 2017

Instructions

  1. Buy steak meat (ribeye, new york,etc) (e.g. from Costco)
  2. Measure the thickness of the steak, e.g. 1.25 inches thick
  3. Smear 1.5 tablespoons of olive oil on both sides of meat
  4. Put salt and pepper on both sides of meat (don’t be afraid to put more than you think – the thicker the meat, the more the salt and pepper)
  5. Put extra heavy duty aluminum foil on a baking sheet or a glass casserole dish (this will make cleanup easy)
  6. Put marinated meat on baking sheet / casserole dish
  7. Put oven rack about 3 to 4 inches from the top of the oven
  8. Turn on oven to “Broil” (only top has flames or heat) and preheat oven for 5 minutes
  9. Put in meat on the rack
  10. Set timer to cook 1st side
  11. When timer goes off, flip the meat and set timer to cook 2nd side.

Notes from JS Conference Workshop: Mastering Chrome Developer Tools

Posted on Mar 16, 2017

JavaScript Debugging

There’s an ability to blackbox JavaScript libraries like jQuery so that when you step over lines of code, you’ll step over these 3rd party libraries. There’s also an ability to set breakpoints on event listeners which can be very handy. Under Settings, you can globally blackbox 3rd JS libraries so you don’t have to blackbox every time you open Chrome. There’s also the ability to create conditional breakpoints, e.g. to break when your about to execute an XHR (AJAX) request to a certain URL.

Editing CSS

When you edit CSS in the Elements tab, you can have those edits write to the source CSS file, and vice-verse from the source file to Chrome. This only works for CSS. To do this, drag your CSS file or entire project folder into the Sources tab. If Chrome can’t auto-map, you can manually map the CSS file.

Stereo vs Surround Sound

Posted on Dec 10, 2016

A lot of people don’t really understand the difference between stereo and surround sound and usually just assume that surround sound is better. Based on my research, here’s a summary of the differences.

Surround Sound

  • Intended to hear some sounds at different places around you, e.g. an ambulance zooming by in which case you’d hear the siren begin from one side of a room and end on the other
  • Most surround sound systems involve 5 speakers and 1 subwoofer (5.1 system). For long rooms, there may be 7 speakers and 1 subwoofer (7.1 system).
  • Surround sound is most often noticeable in action movies, e.g. you can hear explosions behind you. Surround sound is subtle in drama movies, e.g. you might hear the leaves moving in the background and some traffic in the distance.

Stereo Sound

  • Very little music is recorded in surround sound.
  • Stereo systems require a front left and front right speaker.
  • Stereo creates a sound-field that, more or less, is shaped like a performance stage that is situated in front of you–as if you’re sitting in a theater. Surround sound does too but adds sound at the top, back and sides of you.

Easy Way to Texture Walls and Hide Imperfections

Posted on Nov 16, 2016

I hate texturing walls. Not because I don’t like how most textured walls look (knockdown texture), but because I can never texture a wall to look close enough to how the pros do it and I don’t like having to wait some period of time and trying to knock down the texture compound using a trowel or knockdown tool. After researching various ways to texture a wall, I conducted an experiment and came up with a process and set of tools that I think make it really easily to texture a wall and have it look nice and close enough to professional knockdown-textured walls.

Materials:

Experiment:

I used a drill attachment to mix the texture compound until it became creamy. Then, I painted the texture compound on the test 2’x2′ drywall using each type of applicator.

SEO: Free, Credible Backlinks to Your Website

Posted on Nov 7, 2016

Search engines, particularly Google. consider two primary things when it comes to search engine ranking:

  • Relevant content
  • Credible backlinks / Inbound Links

Relevant content

This one is easy. Just write relevant content. The more, the better. As long as it’s content people actually care about.

Credible Backlinks

This is not easy because you depend on getting other reputable websites linking back to you. Below are different ways to get backlinks. This list will be updated as new discoveries are made.

  • PR
    Getting news outlets to write a story about you is the best way to get credible backlinks but it’s not easy. If CNN had written an article about your website and the article links to your website, you’ll get a boost in search engine ranking. You can hire a PR agency (expensive) or do PR yourself by reaching out to journalists and pitching your story to them. The topic of PR can take up a whole book so I’ll it at this. Basically, if you have a good story, e.g. new product/service launch, new feature launch, etc, you can tell journalists about it who represent news outlets that cater to news related to your story, e.g. a new technology product would be pitched to a technology blog (e.g. TechCrunch).
  • Write your own articles
    There are credible websites that let your contribute content, e.g. how-to guides, that also let you link to the source of information (your website).

  • Video Websites (YouTube, Vimeo)
    These websites will let you add a link to your website in the description section of your video
  • GitHub
  • Pinterest
