The Khan Academy Engineering Career Development guide is still my favorite articulation of what it means to be a great engineer and a great teammate.

An investor was in my TL complaining about big tech leaving the AI field open. But it is things like “agentic” applications where they will succeed. Remember the wardley maps, as LLMs become commodities, the value is up the stack.
Thought for the Day. Amazon in "Agentic" Life. While Google knows intent, no one knows more of what you actually buy (and how you live) than Amazon. From your purchases to grocery lists (on Alexa), TV shows you watch and the books you read. When you think about about the application of AI to improve "life" Amazon has to be at the top of the list. Amazon is uniquely positioned to proactively engage in conversations and recommendations, which is a lot more convenient than manually typing instructions to scrape 50 websites for prices (IMHO). We are in the early stages of an "agentic landgrab". Trusted parties with existing data and devices have a huge advantage.

This and the head of the thread are worth reading for founders. Moats are back.

Looking for -Complexity barriers: Is it hard to solve technically and will it stay that way? -data or network effects -integrations/workflow stickiness: is it deeply integrated? -compliance/security

So much on my unvisited TL about new approaches to hashing. Great reads.
1/14 Go's new map implementation in 1.24 is powered by Swiss Tables, a cutting-edge hash table design that significantly boosts performance. Let's break down why this matters and how @CockroachDB's implementation played a key role. 🧐🚀

Darren Cahill and James Blake supporting Djokovic. Jannik Sinners coach, Australian Darren Cahill stated what Tony Jones said was totally inappropriate and especially after what Djokovic went through in 2022 and he has the right to ask for an apology.

Currently playing - “it’s time”, Jackie McLean. 1964: McLean, Hancock, Haynes, Tolliver. Great transitory time for jazz. What’s not to like?

If you are serious about performance engineering, this paper is a must read .. Eytzinger layout based binary search with prefetching is used in TigetBeetle AFAIR and this enumeration has been used in a number of implementations of heaps, segment trees and binary tree data structures. I remember reading the Brodal et al paper some time back and vEB was the fastest layout based on their implementation. But I think with modern hardware advancements Eytzinger layout is possibly the best today .. links: 👇

I (finally) wrote up my thoughts on "Founder Mode" and the Brian Chesky morality tale about how he turned around Airbnb culture. This has made it into the Silicon Valley water table; it must be dealt with. Let's find the nuggets of gold under all the 💩. charity.wtf/2024/12/17/found…

Just dropped: The State of Fintech 2025. The age of the Fintech Hyperscaler. Fintech companies are growing faster than incumbents and will soon be the largest companies in their category. Includes - Every bank job title will have an AI Agent team replacing labor. The first adopters will be Fintech companies not incumbents. - Embedded finance will come roaring back in 2025, as regulatory pressures ease. - Big banks had a banner year helped by rising rates and a return of investment banking income - Digital banks outside the US continue to become some of the biggest in their region, will more Neobanks get charters in the US in 2025? I think yes. Find it at the link in my bio.

Here's a fascinating story of how researchers used Bloom filters cleverly to make SQLite 10x faster. I'll also explain some database internals and how databases implement joins. Let's dive in!

I can now run a GPT-4 class model on my laptop (The exact same laptop that could just about run a GPT-3 class model 20 months ago) The new Llama 3.3 70B is a striking example of the huge efficiency gains we've seen in the last two years

I can echo this is a good approach. It’s been quite successful in using third party APIs, certainly gets you producing testable code quicker.
Building software that integrates with external systems is such a pain. First you need to understand each system (auth and APIs) then you need to build tooling that does the integration. I find using chat gpt to narrow context and solve individual problems that lead to the whole solution extremely valuable.

Here are two jarring facts. The chancellor has just appointed a special Covid corruption commissioner to examine an eye-watering £7.6bn of dodgy and fraudulent contracts awarded for Covid equipment, and the PM has just appointed as cabinet secretary Chris Wormald, who is the top official in the Department of Health and Social Care, which oversaw the awarding of the dodgy contracts. The juxtaposition of the appointments is astonishing, quite literally. I am intrigued by what Keir Starmer asked Wormald about his financial stewardship of DHSC during the job interview. What is Wormald’s explanation for how such spectacularly loss-making medical procurement - that has explicitly and repeatedly been described by Rachel Reeves as a scandal - happened on his watch, when he was the accounting officer? Who does Wormald think was to blame for awarding the disastrous loss-making contracts? Where does the buck stop for the debacle? It can’t be his fault, surely, or presumably Starmer would not have promoted him to run the entire civil service? So who was at fault? Tricky to blame the tooth fairy for this one. Is it plausible that the corruption commissioner and the separate Covid Inquiry will give the DHSC a clean bill of health as they go through purchasing procedures and the books? That seems a stretch after the National Audit Office has said the department has written off a staggering £9.9bn on unusable and over-priced personal protective equipment? If they savage the DHSC, does Downing St already have a media plan to protect Wormald and blame others. Everyone tells me that Wormald is sensible and impressive.  “He is interested in substance and not just a courtier” says someone who knows him and rates him highly. And lest we forget, the country and the government were in panic mode during the early Covid months, so accidents were bound to happen, milk was inevitably going to be spilled. It was a crisis after all and the NHS was chronically short of PPE protective equipment - though whose faults was that? But the difficulty with saying forgive and forget, don’t get worked up, is that the Chancellor says precisely the opposite. She insists the lost billions are a scandal and we should all be very angry.  Though presumably Starmer has misplaced her memo
