Trying to figure out how to include a question mark in your HTTP GET request query strings? Simply swap out the ‘?’ for ‘%3F’. For example, if you wanted to search DuckDuckGo for the following question:
“who won the superbowl?”
You could use use a URL that looks something like:

Having trouble getting your images to show up in the launch screen of your iPhone app? The answer to this problem is pretty ridiculous: reboot your device! I was riding the struggle bus for awhile trying to uncover the answer to this doozy before stumbling upon Flexicoder’s answer on Stack Overflow.
The first thing I tried doing was to run the app on the simulator instead of on my physical iPhone, and sure enough my launch screen image showed up right away. Then after rebooting my iPhone, I was able to get the launch screen image to start displaying on my physical device as well. So cheers to Flexicoder and his solution which have been upvoted 270 times:
Confession: I hate Git. Heresy, I know. But true nonetheless. And I suppose that’s what brings you here. You made a mistake. You pushed several commits to the MASTER branch of your GitHub repository, but have now have had a change of heart. You’ve decided that you’d like to go back to the good ol days, a few commits ago actually. That’s what you want, but Git doesn’t care.
Awful isn’t it!?!? All you want to do is something fairly straight forward, reset your project back to a previous point in time, and Git does not want to allow you to do this. Checkout a previous commit? No problem! Push this commit to MASTER? Absolutely not!
Well luckily, I found an excellent tutorial on YouTube tonight on how to do this. It isn’t super simple. It probably isn’t the way the professionals do it. It probably doesn’t follow “best practices.” However, it works:
// From "merge -s ours" on YouTube by Colten Jackson
$ git checkout 1234321
$ git merge -s ours master
#### that merge will leave you in detached head, use "git log" to get latest commit hash, shown here as 9876789 #####
At the moment I’m currently doing a little hacking in Golang, and just wanted to post this quick little example of how to work with an api and parse json data in Go. Unlike some of the other languages I’ve worked with, in Golang you will need to create a struct to represent the JSON data you are receiving from the API endpoint you are hitting. That’s the trickiest part in my opinion. Also, the JSON data you will be working with is going to be an array of bytes, not a string. Last, you’ll use json.Unmarshal to parse your JSON and extract the information you are looking for.
Unfortunately, I don’t have time to write up a detailed post about how all of this works. However, I think the code snippet below is pretty cool and should provide a good reference if you happen to be playing around with APIs and JSON using Go. Note, the code below is using RapidAPI’s Hacker News endpoint to provide the JSON data. So if you’d like to try running this code yourself, make sure to visit rapidapi.com, register for an account, and replace the API key below with your own. Enjoy!

UPDATE (1/27/2020): Remember to use a JSON to Golang Struct Conversion Tool such as JSON-to-Go to easily map Golang Structs to the JSON objects you want to decode. The code snippet below provides a good example of a struct created with JSON-to-Go:
Having trouble getting started with WebSockets in React Native? I’ve got the answer you’re looking for! After many hours of messing around with WebSockets in React Native for the first time today I’ve made some discoveries that hopefully will be of use to someone else out there on the internet.
The next stumbling block you might run into is setting up your own WebSocket server. For me, this ended up being a lot trickier than simply setting up a WebSocket server for a web app. I have setup WebSocket servers for both NodeJS and Flask web apps fairly easily, but doing the same with React Native gave me a lot of problems. So what I found extremely helpful was to use a test endpoint from a 3rd party that simply echos back any WebSocket messages sent from my app.
After a days work fumbling around, riding the struggle bus, I present a super simple quick start template for getting up and running with WebSockets in React Native. The endpoint URL in the code points to the 3rd party WebSocket test endpoint described above, so the solution below should work as is with no modification necessary. Just create a new React Native app, delete the contents of your App.js file, and copy & paste the code below, and you should be well on your way! (and this way, you will know your React Native app is working properly and playing nice with WebSockets before you start messing around with your server side code. Also, remember to avoid Socket.IO if you want to use the built-in WebSocket API like in my example:
Over the past two days I’ve been pretty stumped working on this new database for my latest app, Moolabeast. I’ve been experimenting with different table designs etc., and discovered what I really need is a FULL JOIN. Great! But just one problem… MySQL doesn’t support FULL JOINS. Yikes!
On StackOverflow I found a bunch of different posts from developers describing how to “fake” a FULL JOIN using various SQL statements that were a little beyond my comprehension. However, I finally found an excellent blog post from TablePlus explaining how this works.
Therefore, if you find yourself struggling to do a FULL JOIN in MySQL, I suggest checking out TablePlus’s explanation. I don’t think I could do it justice! It took me a while to find a really good post on the subject, thus that’s why I wanted to write this post to point more people in the right direction.
Essentially you need to do a LEFT JOIN, and a RIGHT JOIN, and then a UNION which will merge the results of the two joins. Now it isn’t perfect, but it’s probably close enough:
Having trouble dismissing the keyboard in your React Native app on iOS? Would you like the keyboard to simply go away after a user taps somewhere else on the screen after entering some text into a TextInput? Here’s what you’re looking for: <TouchableWithoutFeedback> and Keyboard.dismiss() are the React Native equivalents of Tap Gesture Recognizer and resignFirstResponder. Simply wrap your view in a <TouchableWithoutFeedback> component and call the Keyboard.dismiss() method onPress and the keyboard will automatically dismiss itself when a user taps an area of the screen outside of the currently selected <TextInput>:
