Math You Might Find Useful For Daily Problem Solving

Order of operations

Parenthesis, Exponents/Power, Multiplication, Division/Modulus, Addition, Subtraction

Notation example
(a2 * b) + c – d
1. a2
2. * b
3. + c
4. – d

Proportions

a / A = x / X

a   b
=
A   B

You’re trying to solve x. You have to cross-multiply. Be mindful of order of operations.

x * A = a * X
x = a * X / A

WordPress 5.8 Adds WEBP Image Format Support

Testing it out. Not a fan of it. It works, but only because I’m previewing it in Chrome. However, it’s slow to load maybe because it’s doing some additional Javascripting to make it work. So unless there is native support, I wouldn’t recommend using WEBP images just yet.

How To View HTML Source Without Loading The Actual HTML

In Chrome and Firefox, you can view a web page’s source code directly by typing into the URL bar:

view-source:[webpage address goes here]

for example:
view-source:http://www.example.com

And that will load the source code without actually loading the HTML. This is useful if you don’t want any popups or malicious code to execute, or you’re debugging a webpage.

How To Login To Twitter Normally

UPDATE – Doesn’t seem to work all the time. What a joke.

If you’ve tried to login to Twitter but found it redirecting you to https://twitter.com/i/flow/login and it might spook you thinking it’s malicious (I don’t blame you). But it’s just Twitter’s mobile phone login, they’re trying to be like Google and keep track of all your different devices. Here’s how you’d get the original “normal” login.

Using a browser like Google Chrome, you have to use Incognito Mode so that it doesn’t store cookies. First, clear your browsing history and cookies. Then try logging into Twitter again. Hopefully, the flow login isn’t triggered and you get some peace of mind now. Hope it helps!

Or try this https://twitter.com/login?lang=en-gb otherwise, SOL.

How To Fix Windows 10 Icons Not Updating

How To Fix Windows 10 Icons Not Updating
By Chongchen Saelee

I found a link to instructions that actually works for Windows 10 icons not updating. Prior to Windows 10, the icons were stored in %userprofile%\AppData\Local\IconCache.db and all you had to do was delete that file and kill explorer.exe and start it again. At least, that seemed to work perfectly in Windows 7.

In Windows 10, you’re lucky if it updates the icons completely. You can follow the same steps, and it might work partially, but you’ll notice some icon sizes not updating. It’s associated to the filename and folder, so it’s cached somewhere else!

Well, indeed, Windows 10 stores multiple databases for all different icon sizes now, and in a whole different folder %homepath%\AppData\Local\Microsoft\Windows\Explorer. So you’re gonna have to delete all of those database cache files in order to properly update your Windows 10 icons!

This article gives you the details on how to do it properly:

Hope this helps anyone from pulling their hair out.

Using Now Patent-Free MP3 Audio Format For Your Indie Games

Originally published on December 12, 2020

I’m super late posting this, as the news happened THREE YEARS AGO and the media didn’t spread the word. Anyway, as of 2017, the MP3 audio format is now patent-free. It doesn’t mean that you can now pirate all the commercial songs you want. What it actually means is now that the audio format is patent-free, you can implement an MP3 encoder/decoder into your game engine! That’s sweet! (more…)

Solution: Laptop audio/video is slow, crackling, out of sync

Solution: Laptop audio/video is slow, crackling, out of sync
By Chongchen Saelee

If your laptop seemingly is slowing down in performance, you hear audio crackling, your video is sluggish and not synced with the audio, then make sure your laptop battery is in good condition. Odds are, your laptop is literally in its last breath of life, like literally only 10% health. Replace it with a brand new fully recharged laptop battery and see if this solves your problem! You’ll know your old battery is about to die if it is physically bloated. So time to throw it out and replace it. Hope that helps!

Troubleshooting: When Your PC Doesn’t Boot or Overheats After Cleaning


Troubleshooting: When Your PC Doesn’t Boot or Overheats After Cleaning
By Chongchen Saelee

If you’re lucky, you can go maybe a full year or two without cleaning your computer. But you have to be careful. You can’t just on a whim do a complete disassembly and cleaning. You need to have spare parts lying around just in case you break something or need things replaced like dried up thermal paste. So always make sure you have spare parts and supplies around before doing anything.

Anyway, I won’t get into how to clean your computer, but I will get into how to figure out why afterwards your computer won’t boot up or there is a BIOS warning that your CPU is overheating. Check for these:

  • Did you apply thermal paste on the CPU surface correctly? You should only apply a very small amount, some say the size of a pea, but I say the size of two grains of rice. Make sure that you are pushing down on the heatsink onto the CPU with balanced pressure so that no air pockets are in connected surfaces. Too much thermal paste could store heat, too little will not displace heat.
  • Did you make sure anything you disassembled, you re-assembled correctly? For example, if the cables aren’t plugged in completely, especially the motherboard or CPU’s power cable, then the CPU knows to throttle power or give a warning so that it doesn’t fry itself. If you ignore these symptoms, you’re looking for major malfunction.
  • If there is no video output, then make sure your graphics card is properly seated in its slot. Make sure the graphics card’s power cable is connected properly. If you replaced the GPU’s thermal pad or paste, make sure that it has complete contact between the heatsink and GPU chip.

The big no-nos when it comes to handling computer parts:

  • Don’t drop anything!
  • Don’t discharge any static or electricity on sensitive parts. Not only will you damage the hardware, if you end up electrocuting yourself, your hardware’s not gonna mourn for you.

For the most part, assuming you aren’t grossly incompetent or just plain don’t know what you are doing, then things should go smoothly. You’d have to really want to break your machine for it to not to work anymore. Most of the time when your computer doesn’t work even though previously it did, it’s because of simple human error.

Good luck!

How To Fix Locked CD Tray Caused By Cyberlink PowerDVD 17 for Windows 7

Stuck CD tray

How To Fix Locked CD Tray Caused By Cyberlink PowerDVD 17 for Windows 7

Copyright © 2019 By Chongchen Saelee

If you’ve previously used Cyberlink PowerDVD 17 (or previous versions) to watch your Blu-ray disc movies, you might encounter a problem the next time you use the program again when you seemingly cannot open your CD tray. The CD tray might eject partially and then quickly return into the slot. It’s as though gremlins have hijacked your CD tray and messing with you!

Fear not, it’s not a virus. It’s definitely not gremlins. It’s because PowerDVD 17 has stored some data in it’s cache system thinking a disc is still in the CD tray. I assume it does this for DRM (digital rights management) purposes, to prevent users from copying the movies. Anyway, while that data is still in PowerDVD 17’s cache, you won’t be able to get that CD tray open. So you need to CLEAR THE CACHE. (more…)
