Ain't nothing better than chilling and writing a highly efficient log reader from scratch, using file binary search and the Go programming language. Find yourself a set of headphones and let's chill
together, while coding a bad ass CLI program in Go. In this video we'll be coding an efficient Apache Log Reader from scratch.

Another Code Time about Concurrency in Go. As Go developers, we all know Atomics and Mutexes both can be used to prevent Race Conditions, and they both provide ways to make sure our Go programs execute correctly. The question is, can we mix the 2 primitives to achieve Correctness? What do you think will be the result of this program when executed with the -race flag?

▶️ go run -race main.go

1️⃣
Race Condition
Print → count: 100000
2️⃣
No Race Condition
Print → count: 100000
3️⃣
Race Condition
Print → count: anything up to 100000
4️⃣
Race Condition
No Race Condition
Print → count: anything up to 100000

Feels good to be back after some time taken off. I'll start things slow with a good old Code Time post. While slices are a simple and useful data structure in Go, they can give you a headache, if you're not aware of their internals. So what's it going to be? 🤔

✅ 1

Your weekly quiz like always. This one about json.Unmarshal really surprised me 🙀

So what will the result going to be?
✅ 1
✅ 2
✅ 3
✅ json unmarshal error

Here's a small hint for you 💡 https://github.com/golang/go/blob/master/src/encoding/json/decode.go

The Software Engineering industry is changing at a very fast pace and it can be exhausting for many of us. As developers, we must always keep up with the technology, we're in a never ending learning business. The problem is, there's too much new/experimental/trendy stuff happening, which can burn you out 🔥

My take on this one is, keep an eye on what's coming up, but don't spend your time & energy on catching up with all the trends. Focus on you as an Engineer. Become a better Thinker, better Problem Solver & only adopt trends as they become a standard 👀 💪

This one is nothing fancy but it really blew my mind 🙀
Will the below code panic?

✅ YES
✅ NO

Every single time I find someone who's better than me, I start comparing myself, thinking I'm not enough. My math is wrong most of the times though, you can't compare somebody's 10 years of experience with your 2-3 years of experience. It does not work that way, even if you had the same experience in terms of years, that's still a wrong approach. We're all different, we function differently 🙀

Bottom line: The only person you must ever compare yourself with is YOU. Do it daily, become better than you were yesterday 💪

I know this sounds crazy, but it works. From my experience so far, correcting a bad negotiation can be done by simply moving on. Hate it or Like it, Raises & Upgrades are usually up to 15-20% (if you're lucky) If we're talking higher raises the business won't like you, so it's just easier to leave. Negotiation is Key, Don't Mess it Up 💪😉

The tip of this week, is nothing fancy. It's about Persistent TCP Connections. If you've ever created TCP servers & clients, you probably considered the idea of reusing the same TCP connection for efficiently using the networking resources. There are a set of issues that come with this approach, which can cause reading & writing to block forever.

To solve this we need to satisfy 3 things:

✅ TCP Stream Delimiter Defined
Because we want to reuse the TCP Connection, we must have defined some kind of delimiter/separator based on which we scan/read a single message from the TCP Connection. The default one (bufio.Scanner) is scanning lines (by \n separator).

✅ The Delimiter MUST be Bidirectional
The separator/delimiter must be supported on both ends, the client & server on both operations: the read & write to the TCP stream. If at least 1 is not implemented, the reading/writing process is going to end up blocking forever.

✅ Rate Limit TCP Connections
Because we don't close the TCP Connections, we might run into physical limitations, as to how many connections can be open at the same time. This is why we must have some kind of rate limiting implemented to make sure our system is not breaking.

We can't make use of util functions like ioutil.ReadAll, because we rely on not closing the TCP connection. Plus pretty much all Readers (io.Reader) supported by Go, will read till they reach EOF. An EOF is never written to the TCP stream, because we don't close the connection 🤔

This one's very opinionated, but that's my conclusion. You will never get fully tested in an interview, nor will you get a super objective appreciation. It very much depends on who's interviewing you & how they do it. At the end of the day, just be cool & don't stress it. Some people will barely touch you, others will shred you. The point is, stay working & don't stress too much
about how an interview went 💪🎯

On this one I'll be the Developer's Advocate. What's worse than a missing feature that makes you money? Probably a feature which is buggy or has future limitations. Deadlines & Delivery are important but, Quality takes time. 🎯

As usual your weekly quiz, this time around let's exercise your knowledge on gob encoding. Go has most encoding standards supported, including its own encoding gob: for communicating between Go processes. So what's going to be the value of q?

✅ Q{A: 1, B: 2}
✅ Decode Error

Being part of the Code Review process does not only make you a better Software Engineer, but also a better human. I won't make this one too long & I'll just say this: DON'T MAKE CODE REVIEWS MEANINGLESS. Try and bring as much value to the table, and be Humble. Admit when you're wrong. We're all wrong at some point, we all make mistakes, that's not the point. Code Reviews are a Team Effort 💻❤️

We're past the times when Memorising was a thing. CREATIVITY & CRITICAL THINKING are way more important, so don't waste your time on memorising what automated tools, docs & specs already do fo you. Work Efficiently, not Hard, Be a real Problem Solver 💪🎯

I'm a huge fan of the Hustle Culture, but the Software Engineering game is like sports. You Workout, you Rest, then Get Back to Workout.

It's just part of the process, make sure to put in as much work as possible, but Don't Burn Out. Enjoy the PROCESS, take some time to chill & get back in 💪😌💪

This post is not about me bragging or licking my past scars, It's about Speaking for others, Encouragement & Love. I've only shared this with a small number of people, so a small number of you may know, however the majority of you don't know.

And now, to anyone who wants to become a Software Engineer, let me tell you something which you won't hear from many.

You're now looking at the kid who grew up without both of his parents, lived in a dorm with only $9/week, was constantly told that Software Engineering is a joke while being in the orphanage & In the End I STILL MADE IT.

I am thankful & grateful to all the people who helped me & supported me. I appreciate the hard times & the people that showed up in those hard times. I had a high chance of not making it, but at the end of the day in the worst moments, we can still make the best choices.

Find the Strength & Motivation within you & You'll Achieve ANYTHING. IF IT WORKED FOR ME, IT HAS TO WORK FOR YOU TOO 💪

The greatest enemy of Growth is the Comfort Zone. There are stages in our careers when we reach a level of comfort, and we slowly stop growing. The key is to always find new things to do/learn, that light up that spark, that keep you as hungry as you were in the beginning.

Learning really has no levels, maybe only Chuck Norris has passed all the levels twice, for the rest of us, find what sets you on fire 🔥

Following the 10,000 hours rule. If you work 14h/day you become a Senior in 3 years, instead of 5 years. 🙀
There’s NO SECRET, it’s just Difference in WORK 💪

Mutexes can go wrong in so many ways, it's just stuff you always have to manage correctly, otherwise you run into a bunch of Concurrency Issues. Here's an example of Bad vs Good usage (reducing mutex holding time) ⬇️

❌ AVOID GENERALISING the SCOPE.
A top level call to Lock() and defer Unlock() will make things slow, especially in a production environment

✅ Always NARROW DOWN the SCOPE as much as you can
This will release the lock faster and thus allow the new acquire of the lock much faster

The Software Engineering game can be wild, but it's not about that. Most of the times it's emotionally hard to deal with Rejection & Self Doubt, which happen often in our careers.

It's important to understand that part of any success, there's a ton of failure, rejection & self doubt. It's how we all grow.

A REJECTION can mean one of the 2:
1️⃣ You Need to Grow
2️⃣ They couldn't handle your Honesty

Don't discourage yourself, it's all gonna be alright, you'll look past this after some time and understand it's always been part of the process, part of your successful journey.

Stay Strong, Love y'all ❤️

As perfect as we all try to be 😇, especially myself, I had to say it.
F**K PERFECTION 🤬. Go ahead and put in the WORK, MAKE MISTAKES and REPEAT the damn process. It's the way, it's the silver bullet.

03/08/2021

There's NO SECRET or SHORT PATH towards anything. WORK is the only decisive factor in any sort of SUCCESS.

I don't care who you are:
man / woman / LGBT+,
black / white / asian,
religious or not,
speak perfect / broken English,
dress well
how old are you
or really anything that makes you different.

I DON'T CARE, that's just irrelevant,
You get my respect, if you're a hustler & put in the hard work.
Keep grinding & improving the game. 👨‍💻

Been a while since I hit ya with another code time. Here we go again. You might think locks in Go are re-entrant, to your surprise they're not. So what's it going to be? 🤔

✅ Works fine
✅ Deadlock
