Debugging a Wordle Bug |
https://dev.to/codenameone/debugging-a-wordle-bug-4n0a
|
Debugging a Wordle BugI have a confession I m addicted to Wordle Especially now that it s out of style and people don t post about it I love that it s short I can solve one word and then it s gone I don t feel too bad about the addiction and wasting my time with a game This cloud debugger tutorial is an enormous challenge for me since the target is a Wordle game But I m getting ahead of myself As part of the Lightrun Playground we recently released we needed a demo application that will let developers who are new to Lightrun practice in a safe environment We decided to pick Wordle as our demo application because it s instantly familiar visual and not too interactive A Flappy Bird demo might have been painful to debug At this point our key challenge was in creating a bug where the debugging process would be interesting enough and yet subtle enough so it won t be instantly obvious Creating a bug like that is surprisingly challenging We don t want an overly complex application spanning multiple files That might make the debugging process too difficult On the other hand the bug needs to be subtle enough that we won t notice it even if we stare directly at it Here is the bug constguess for leti i lt game word length i if game word includes guessWord i guess push letter guessWord i check CHECK TYPES LETTER INCLUDED else if guessWord i game word i guess push letter guessWord i check CHECK TYPES LETTER MATCHED else guess push letter guessWord i check CHECK TYPES LETTER NOT INCLUDED Can you spot the problem To understand it we need to first understand the symptom of the bug we chose When I talk about bugs people s minds often go to crashes That can be the case sometimes but in my experience the most frequent bugs are logic mistakes that occur because the production environment differs in some subtle way from our testing environment Because of that we picked a logic bug unfortunately because of the simplicity constraint I doubt a bug like that would have made it to production The core lesson still applies The bug in this case is that letters in Wordle that should be colored in green because they re in the right position in the word are colored in yellow This logic is implemented by the code we see above As you can see we have three modes CHECK TYPES LETTER INCLUDED indicates that a letter should be colored in yellowCHECK TYPES LETTER MATCHED indicates that the letter should be colored in greenCHECK TYPES LETTER NOT INCLUDED indicates that the letter is missing and should be grayCan you spot the problem now Don t scroll down to avoid spoilers Here s working code constguess for leti i lt game word length i if game word includes guessWord i guess push letter guessWord i check CHECK TYPES LETTER MATCHED else if guessWord i game word i guess push letter guessWord i check CHECK TYPES LETTER INCLUDED else guess push letter guessWord i check CHECK TYPES LETTER NOT INCLUDED The difference is that I swapped two lines of code We need CHECK TYPES LETTER MATCHED to be tested before the CHECK TYPES LETTER INCLUDED test The tests must be in order of significance and green perfect match should precede the yellow partial match The process of debugging this is relatively simple We placed a snapshot breakpoint on the following line where we saw the values were incorrect at the server code level I think a more natural way to debug this would have been to place a breakpoint on the CHECK TYPES LETTER MATCHED line and once we realize that this was never hit we would have understood what went wrong For our particular use case of a playground that wasn t the right approach We wanted people to see the snapshot non breaking breakpoint getting hit But other than that it s a good bug If this still isn t clear we have this cool animation in the playground that explains the bug visually Teaching DebuggingDebugging is one of those subjects that we don t learn at University Yes there are courses that cover it but not much You re mostly expected to pick it up on your own for example using a dedicated live debugging tool This shows to a large part why that s the case It s very hard to create exercises for debugging and even harder to test knowledge We could create a more elaborate demo to debug but there we transition to the world of understanding and explaining that code base This isn t the goal I ve gone over a lot of debugging related materials over the past couple of years and this seems to be a universal problem that all of us are struggling with This is a shame since there are so many tools techniques and approaches that even experienced developers are missing out on In that sense I m a proponent of teaching debugging without a bug Debuggers are tools we can explore and use before we have any bug even as a learning tool I think we need to be “comfortable within the debugging environment and should leverage it when there are no bugs It shouldn t be a tool we only reach for in the case of an emergency If we work with a debugger on a regular basis it will be much easier to track bugs with it when we actually need it This is a philosophy I hold for tools such as observability tools logs etc Muscles that we don t flex on a regular basis lose their mass and weaken Synthetic problems are OK for a short tutorial but we can t use them daily and it s hard to scale them to a full blown workshop or course FinallyHow do you feel about the way you learned debugging Was it in college university bootcamp or on the job Do you feel you know the subject well Do you teach debugging to others If so how and what techniques do you use What do you find works best I d love to hear from you on Twitter debugagent my dms are open LinkedIn or comments or any other channel Private or public As a reminder our Playground is open for business feel free to roam around test our your debugging skills and report back |

I was scammed by a rip off bar last night What should I do Hello I don t know if this is the best sub to post this but I figure it s a good start I ve recently moved to Tokyo to study at Waseda University I was out last night by myself and went to a few bars in Shinjuku On my way home I got grabbed and pulled into an elevator by some guy and brought up to a sketchy bar I know that alarm bells should have been going off but I was a bit tipsy and didn t really know what was going on I ordered a gin and tonic and I m sure it was spiked because I truly don t remember what happened other than they took me to an atm and my bank In America wouldn t let me withdraw however much money they were asking They got me to use my phone and PayPal them yen and then sent me on my way I woke up this morning to that charge and truly do not know what happened other than bits and pieces Should I go to the police submitted by u ThrowRAmegaconfused to r japanlife link comments |
