Great tips from @mklin, @camachoyury, @KatieBarnett_5 , @inpurefunction and @mikehughestweet - just 4 of 20+ sessions at #GDGSummit #io19
My post on Redis blew up. And the replies were flooded with devs all saying the same thing: Stop telling people to cache slow queries. Fix your database itself. They are 100% correct. Let's be crystal clear, because this is the golden rule: Your database is the one place your…
Your app is slow. Your users are waiting 3, 4, maybe 5 seconds for a page to load. You check your logs. The problem isn't your code. It's your database. It's on fire. It's spending all its time running the same complex 'SELECT' queries with 'JOINs' and 'ORDER BY' clauses, over…
Redis started timing out randomly. 1-2 times per hour. Operation that should take 2ms was taking 5+ seconds. What we checked: - Memory: 40% used (plenty available) - CPU: 12% average - Network: normal - No slow queries in logs - Replication lag: 0ms Enabled Redis slow log…
What caused the AWS outage that felt like it took down half the internet on Monday? It started with a race condition in DynamoDB's DNS propagation, which ended up setting the dynamod.us-east-1 .amazonaws .com DNS to empty. A deepdive and more details: blog.pragmaticengineer.com/aws-outage-us-…
It finally happened. I've got a giant merge conflict and both sides were vibe coded and I don't recognize either. Now I'm vibe merging the conflicts too
Yah.. eu vivo numa bolha 🤣
Bom dia, lembrem-se de denunciar vossos amigos pedófilos que andam com meninas de 15 anos. Boa semana e que Deus vos abençoe.
80% of my Twitter feed is raigebaits based on half-truths... and well, bots
I feel like this is something I should have known but TIL that db query planners can decide to use different indexes locally then the ones used in production for the same query.
🤣🤣🤣 Uma é senhora directora por respeito, outra é tia da limpeza por carinho. yah , carinho is overrated.
Ai moça, desculpa! Mas continuarei, pq é eu enxergo como uma forma de carinho. Se a pessoa disser que não gosta, ok! Mas eu demostro afeto assim, inclusive, algumas chamo até de “mô”!
Finalmente algum reconhecimento 😀
Moçambique é o único país sem um campeonato nacional e que tem ambições de ir ao mundial. Desejar que os mambas vão ao mundial jogar contra a Alemanha é um acto de má fé. E se por acaso nos apurássemos, começava outra crise: não há dinheiro para estágios, para prêmios…
"we're going to offer them 10,000x leverage so they can try & make it all back"
social media is great at validating your biases .

Isto me lembra do Chapo toda hora a falar de guerra civil dos 16 anos. 🤦🏾♂️🤦🏾♂️🤦🏾♂️🤦🏾♂️
From 1946 to 1975, Vietnam was in 29 years of continuous wars; 8 years fighting France, 20 years of civil war, and 8 years fighting the US. Today, unlike Nigerians who still blame colonialism, Vietnam has 100% electricity and far higher HDI and GDP than Nigeria.
PM: Users are begging for customization options. Look at this feedback. Lead PM: Show me the usage data. PM: 92% never change the defaults. Lead PM: Interesting paradox. PM: Not a paradox. The data is wrong. Lead PM: The data is never wrong. Your interpretation might be.…
Lol how do we even survive this 🤣! The same people who build complex and amazing things are also writing think pieces and tales of bravery for deciding to call their branches "master" 🥲. Explaining this to someone outside of the industry, would be challenging at least.
One thing that’s annoying about being a software engineer is that you’re surrounded by people who have strong opinions about the stupidest possible stuff that couldn’t possibly ever matter even a little bit. This is your whole career. It’s just arguments like this one over and…
O primeiro sinal de chatGPT 😀
I'm going through a bunch of job applications at the moment and 80% of cover letters contain at least 4 em dashes.
São sempre "memes" que nos põem no mapa🤣
He destroyed his own gate when his wife declined to open it.
🥲 nossos congéneres nos envergonham yah!
Na faculdade, um professor chamou-me ao gabinete e tentou beijar-me. Consegui empurrá-lo e fugi. Meses depois, uma colega que passou pelo mesmo ou pior pediu-me para testemunhar contra ele, mas não o fiz por ser estrangeira, por ele ter influência e por medo de represálias… +
