The purpose of quadratic voting is to determine “whether the intense preferences of the minority outweigh the weak preferences of the majority,”

This is something I’d like to try in planning meetings.

We’ve repurposed the idea of a technology tree, popular in many strategy video games, and used that as a vehicle to communicate the Up product roadmap.

At The Economist, we take data visualisation seriously. Every week we publish around 40 charts across print, the website and our apps. With every single one, we try our best to visualise the numbers accurately and in a way that best supports the story. But sometimes we get it wrong. We can do better in future if we learn from our mistakes — and other people may be able to learn from them, too.

Herb Caudill:

Once you’ve learned enough that there’s a certain distance between the current version of your product and the best version of that product you can imagine, then the right approach is not to replace your software with a new version, but to build something new next to it — without throwing away what you have.

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.

Instead of working with a thing you love, think about how to work in a way you love.

This is totally my bag.

Still trying to learn how to think better.

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.

The first time any of the above happens on your watch, it’s always new and hard, no matter how many books you’ve read on the topic. But the fifth or tenth time or 20th time it happens, you’re no longer freaked out. You realize that you’ll be fine.

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.

Phil Calçado:

In product development, the closer to the customer a piece of software is, the more often it changes.

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.

Tyler Cowen:

Learning something new all the time, and staying healthy. Getting paid. Interacting with smart people. Having the chance to pass something along to others.

Solid.

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.

Impressive.

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.

What follows is my personal, opinionated, idiosyncratic approach to React/Redux development, forged in half a dozen attempts to pursue test-driven development at a good pace.

Some interesting approaches in here. I like the use of more classic terms for some of the Redux concepts. Commands instead of Action Creators. Events instead of actions. Read models instead of reducers or selectors.

If you are (or were) a highly opinionated engineer, practicing making space for information rather than quickly jumping in and sharing your conclusions is a must for leadership growth.

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.

DHH:

Creativity, progress, and impact does not yield easily or commonly to brute force.

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. Then I realized that we are already surrounded by machines that demonstrate a complete lack of insight, we just call them corporations.
