Startup strategy is like Kung Fu. There are many styles that work. But in a bar fight, you’re going to get punched in the face regardless.

I can only teach you my style. Others can only teach you theirs.

Lots to chew on.

the research is clear: Telling people what we think of their performance doesn’t help them thrive and excel, and telling people how we think they should improve actually hinders learning.

Cindy Sridharan quoting Joe Armstrong:

We should identify the error kernel. The error kernel of a system is that part which must be correct. That’s what the error kernel is. All the other code can be incorrect, it doesn’t matter. The error kernel is the part of the system that must be correct. If it’s incorrect, then all bets are off. The error kernel must be correct.

John D. Cook:

The rule of three gives a quick and dirty way to estimate these kinds of probabilities. It says that if you’ve tested N cases and haven’t found what you’re looking for, a reasonable estimate is that the probability is less than 3/N. So in our proofreading example, if you haven’t found any typos in 20 pages, you could estimate that the probability of a page having a typo is less than 15%.

Hashing syntax trees and storing them directly in a database is very interesting. I’ve long wondered what will come after the grab bag of text files approach we’ve been using to date.

Camille Fournier:

So what are the management skills that are needed to achieve [Engineering productivity]? At the first level of management, they look like:

1. Breaking down the scope of projects to help your team ship frequently. An eye for the MVP, for sequencing work and for predicting likely risks and bottlenecks for project completion are the skills here. This is why I think project management is such an important part of engineering leadership development, and why I hate to hand it off to professional project managers for work that doesn’t cross teams or organizations.

Bingo.

Colm MacCárthaigh:

Now, let’s try a much better, O(1) control plane. DUMB AS ROCKS. Imagine if instead that the customer API pretty much edits a document directly, like a file on S3 or whatever. And imagine the servers just pull that file every few seconds, WHETHER IT CHANGED OR NOT.

This system is O(1). The whole config can change, or none of it, and the servers don’t even care. They are dumb. They just carry on. This is MUCH MUCH more robust. It never lags, it self-heals very quickly, and it’s always ready for a set of events like everyone changing everything at once. The SYSTEM DOES NOT CARE.

Clever.

Jessica Kerr:

If you think about it this way, you might recognize that in many software teams, our limitation is not how much we can do, but how much we can know. To change a sufficiently complex system, we need more knowledge than one or two people can hold. Otherwise we are very slow, or we mess it up and the unintended effects of our change create a ton more work.

An explicit approach to delegation.

Camille Fournier:

So the next time you find yourself tempted to volunteer to take over responsibility for something from someone who reports to you, pause. Instead of taking it over, ask them what they think the next steps should be. Give your feedback, and let them bring the follow-ups to you in the next appropriate touch base. You owe it to them to stop taking over their work in the name of helpfulness.

Tomasz Tunguz:

There are three types of product features, a seasoned head of product told me recently. MMRs, neutralizers, and differentiators. MMRs are minimum market requirements; basic features that every customer expects and demands. Neutralizers mitigate competitive threat. Differentiators are your startup’s competitive advantage.

…

As the product team talks to customers, they are likely to hear feedback encouraging more investment in MMRs and neutralizers. “Your product is missing this feature. We need this capability that exists in another piece of software in yours.”

…

customers rarely push vendors to further their differentiation. By definition, the unique selling proposition doesn’t exist elsewhere in the market. So advances or improvements to the differentiator may not be obvious to customers.

The Tesla’s big battery in South Australia has already taken a 55 per cent share in the state’s frequency and ancillary services market, and lowered prices in that market by 90 per cent, new data has shown.

…

And the 100MW battery has achieved over 55 per cent of the FCAS revenues in South Australia. So it’s 2 per cent of the capacity in South Australia achieving 55 per cent of the revenues in South Australia.

…

Various estimates have put the cost savings to consumers from the FCAS market alone at around $35 million, just in the first four months of its operation.

That’s a pretty good bang for the buck for the estimated $50 million investment by the South Australia government. South Australia is the only state that has experienced a decline in FCAS prices over the past few months.

Joel Spolsky:

I don’t know what the original idea of Twitter was, but it succeeded because of natural selection. In a world where the tech industry was cranking out millions of dumb little social applications, this one happens to limit messages to 140 characters and that happens to create, unintentionally, a subtlety-free indignation machine, which is addictive as heck, so this is the one that survives and thrives and becomes a huge new engine of polarization and anger.

The Case for Learned Index Structures:

Indexes are models: a B-Tree-Index can be seen as a model to map a key to the position of a record within a sorted array, a Hash-Index as a model to map a key to a position of a record within an unsorted array, and a BitMap-Index as a model to indicate if a data record exists or not. In this exploratory research paper, we start from this premise and posit that all existing index structures can be replaced with other types of models, including deep-learning models, which we term learned indexes.

…

Our initial results show, that by using neural nets we are able to outperform cache-optimized B-Trees by up to 70% in speed while saving an order-of-magnitude in memory over several real-world data sets.

I used to find it odd that these hypothetical AIs were supposed to be smart enough to solve problems that no human could, yet they were incapable of doing something most every adult has done: taking a step back and asking whether their current course of action is really a good idea.

Eric Normand:

Rich Hickey explained the design choices behind Clojure and made many statements about static typing along the way. I share an interesting perspective and some stories from my time as a Haskell programmer. I conclude with a design challenge for the statically typed world.

…

People often talk about a Person class representing a person. But it doesn’t. It represents information about a person. A Person type, with certain fields of given types, is a concrete choice about what information you want to keep out of all of the possible choices of what information to track about a person. An abstraction would ignore the particulars and let you store any information about a person. And while you’re at it, it might as well let you store information about anything. There’s something deeper there, which is about having a higher-order notion of data.

It was emotional.

Jamie Talbot:

Having a formal system means we can better support the growth of our engineers. We’re able to have more honest, open conversations about progress, promotions, and opportunity. While the framework is still relatively new, it is showing early promise at incentivising the kinds of behaviours we want to see in the team, and recognising the different kinds of value that people add.

We already have ideas on how to improve the framework further, and plan to continue iterating on it over time. We are releasing it publicly now, in the hope that it can help other companies that are thinking about how to grow and support their employees.
