You get better through consistency over intensity

[John Doe @StanleyMasinde_]

Don't stop posting your work. Sometimes we(or you) get projects to manage, and I'd rather build a team from here than read generic resumes.

Halafu huko GitHub, make sure you have properly documented your repo, have demos, instructions on how to run, etc.

[Puneet Patwari @system_monarch]

I've been a backend Engineer for 12+ years. Today, I'm a Principal Engineer at Atlassian.

I've designed systems that handle millions of requests. Sat on both sides of system design interviews.

Reviewed more architecture docs than I can count.

Starting today, I'm breaking down the fundamentals of scaling for the next 25 days.

If you're learning system design bookmark this thread, you're going to get a lot of learning from this.

Why do most Kenyan tech firms and startups dwell more on software than hardware? I only know of a few startups that work on hardware.

[John Doe @StanleyMasinde_]

I’m still learning. It’s been 8 years (7 professional)

These days I spend my time in big decades old codebases like Nginx, Linux etc

I read the mail list for projects like VLC, a lot of my software are build from source.

You never stop learning because you can create a React Website that leaks memory.

Niliquit 9-5 ilikuwa inanilipa 150k/month.
Imenitake two years for my company kunilipa 67k/month na nafanya kazi from 7AM to 11PM every day, na sometimes unapata uko na employees wanakupea the hardest time ever, na kuwafuta kazi ni even more expensive.

Every month uko na bills za kulipa in the millions, end month kila mtu ako happy isipokuwa wewe juu uko na another 30 days kuraise another million. Na imagine all this trouble ndiyo net salary yako ikuwe 50k

Sometimes doh haitoshi unasema wacha ulipe the employees alafu KRA utawatumia yao by 9th, unajaribu kupata loan bank inakataa juu hauna shamba ya security, inafika 15th unapata weird calls, unashika unapata ni KRA, unawaambia utawalipa next Friday, wanakuambia Friday haiwezekani, labda Thursday. Inabidi uongee with one of your clients akulipe mapema, anakusomea akikuambia biz haifanywi hivo but anaitikia eventually.
Next week inafika unalipa KRA, SHA,NSSF, Housing Levy. Unahave some peace kidogo only to realize that next week ni end month na this time uko na deficit kubwa kushinda last month, and the cycle continues.

Kama uko 9-5 na uko sawa, I can’t advise you to quit. Heri ujaribu entrepreneurship in parallel but usiquit job yako. It feels good when you tell people that you quit your job to pursue your dream but you also need to understand that your dream will take time before it starts paying the bills, and it might also die before you eat a shilling from it.

90% of microservices interviews are basically these 7 questions.

[Vfynn_🥷🏼 𐙚 @Vfynn_]

🚨🗣️ Ian Wright on Mikel Arteta’s Arsenal against Manchester City, and what it means as the season hit its final sprint:

“You know what hurts me watching this Arsenal team right now? It’s not even the result against Manchester City… it’s the feeling that when it really mattered, the personality disappeared.

For seven months you’re top of the league, everyone is talking, everything looks controlled… and then suddenly, in the final sprint, you look like a team hoping instead of believing. That’s the difference.

People will talk tactics, they’ll talk about the goalkeeper going long, or individuals not stepping up but for me, it’s deeper. When City smell that moment, they become ruthless. Arsenal? They became cautious. And in this league, cautious is not enough.

I’ve been there. When you want to win the title, you have to impose yourself even when things go wrong. Today, after it went 1-1, you could feel it… City said ���we take this now,’ and Arsenal almost accepted it.

And that’s why people are asking how did it get to this? Because a month ago, it looked impossible for them to lose it. Now? All the pressure is on them, and City are playing free, with momentum, with experience.

Listen, Mikel Arteta has done an unbelievable job, but this is the stage where you don’t just need structure, you need authority. You need players who say ‘give me the ball, I decide this game.’

Right now, I don’t see that enough. And if you don’t show it at this stage of the season… then you open the door for a team like City. And once that door is open, they don’t knock… they walk through it.”
