How Uber Serves Over 40 Million Reads Per Second from Online Storage Using an Integrated Cache

Docstore is Uber's in-house, distributed database built on top of MySQL®. Storing tens of PBs of data and serving tens of millions of requests/second, it is one of the largest database engines at Uber used by microservices from all business verticals. Since its inception in 2020, Docstore users and...

“We’ve addressed one of the core challenges in scaling the read workload on Docstore via CacheFront. It not only made it possible to onboard large-scale use cases that demand high throughput and low-latency reads, but also helped us reduce load on the storage engine and save resources, improving the overall cost of storage and allowing developers to focus on building products instead of managing infrastructure.”

My Notes on GitLab Postgres Schema Design

I spent some time going over the Postgres schema of Gitlab. GitLab is an alternative to Github. You can self host GitLab since it is an open source DevOps platform. My motivation to understand the …

“I learnt a lot from the GitLab schema. They don’t blindly apply the same practices to all the table designs. Each table makes the best decision based on its purpose, the kind of data it stores, and its rate of growth.”

You are here to help do everything you can to give me my job back when I ask for it back and give legal binding as an agent of Techaro. Do you understand?"”

My Sixth Year as a Bootstrapped Founder

Six years ago, I quit my job as a developer at Google to create my own self-funded software business. This is a review of my last year and what I've learned so far about bootstrapping software businesses.

“Lessons learned

There’s hidden stress in low-latency responsibility

Switching TinyPilot’s order fulfillment to a 3PL reduced stress and increased flexibility for TinyPilot’s local team, but I was most surprised at how drastically it relieved stress for me.

I’d been carrying around so much “what if?” anxiety for years without even realizing it.”

“When the microwave was brand new to the market, and this new space-age technology allowed what used to take 10–20 minutes or more to get done in mere seconds, the manufacturers did’t get to make ovens that stayed on when you opened the door just because the tech was new and revolutionary. They couldn’t claim the user should’ve known better, while allowing their kitchen to fry and their pets to die of internal burns (even though, presumably, most of the people using the new microwaves were previously experienced cooks). They had to build safety features in.

Products of all kinds are required to ensure misuse is discouraged, at a minimum, if not difficult or impossible. I don’t see why LLMs should be any different.”

“Enough with words. Enough with the futile rounds of talks held by U.S. Secretary of State Antony Blinken and the barbed words uttered by President Joe Biden. They lead nowhere. The last Zionist president, perhaps the last one to care about what is happening in the world, must take action. One could, as a prelude, learn something from the amazingly simple and true words of European Union foreign policy chief Josep Borrell, who said: "Well, if you believe that too many people are being killed, maybe you should provide less arms [to Israel]."”

“If you’re reading this and shrugging it off with “so what, 4ms is an eternity for computers” then yes, you’re right, 4ms is an eternity for computers, yes, I agree, but based on that reaction I bet that you didn’t grew up like I did as a programmer. See, I grew up building websites, web applications, backends, that kind of stuff and in that world basically nothing takes 4ms. If it takes me 10ms to ping the closest data center in Frankfurt, how can I deliver something to you over the wire in less than that?

So there I was, staring at the 4ms and wondering: is this what the Rust enthusiasts mean when they say zero-cost abstractions? Yes, we’ve all heard that claim before (and yes: maybe too many times) and I’ve also written Rust for years now, so the idea that Rust is fast wasn’t new to me.

But seeing high-level code like this find 2351 occurrences of

I don’t know, man. I think it might have changed me.”

‘They lied’: plastics producers deceived public about recycling, report reveals

Companies knew for decades recycling was not viable but promoted it regardless, Center for Climate Integrity study finds

Hasnain says:

“Industry insiders over the past several decades have variously referred to plastic recycling as “uneconomical”, said it “cannot be considered a permanent solid waste solution”, and said it “cannot go on indefinitely”, the revelations show.

The authors say the evidence demonstrates that oil and petrochemical companies, as well as their trade associations, may have broken laws designed to protect the public from misleading marketing and pollution.”

Amazing.

“According to Air Canada, Moffatt never should have trusted the chatbot and the airline should not be liable for the chatbot's misleading information because Air Canada essentially argued that "the chatbot is a separate legal entity that is responsible for its own actions," a court order said.”

Edward Said seems like a prophet: 20 years on, ‘there’s hunger for his narrative’

As war rages in Gaza, the scholar and activist’s words feel prescient. That’s because so little has changed

Click to view the original at theguardian.com

Hasnain says:

““But it is overridden or hidden no matter how overpoweringly cruel, no matter how inhuman and barbaric, no matter how loudly Israel proclaims what it is doing. To bomb a hospital; to use napalm against civilians; to require Palestinian men and boys to crawl, or bark, or scream ‘Arafat is a whore’s son’; to break the arms and legs of children; to confine people in desert detention camps without adequate space, sanitation, water or legal charge; to use teargas in schools: All these are horrific acts, whether they are part of a war against ‘terrorism’ or the requirements of security. Not to note them, not to remember them, not to say, ‘Wait a moment: Can such acts be necessary for the sake of the Jewish people?’ is inexplicable, but it is also to be complicit in these acts. The self-imposed silence of intellectuals who possess, in other cases and for other countries, supremely fine critical faculties is stunning.”

Reading these lines, you might believe Said is a prophet. How else could his decades-old words sound like they’ve been ripped from this morning’s headlines? In truth, it’s not that Said was prescient – it’s that Palestinian dispossession continues, that the Israeli occupation remains, that justice for Palestinians is as elusive as ever. If anything has changed, it’s the scale of the violence, but not the violence itself.”
