From Farm to Blockchain: Walmart Tracks Its Lettuce I can't even … (h/t Tracy Alloway)

Blockchains are supposed to make it possible to keep updated databases without any central authority in charge. But currently, all of the records for the Walmart blockchain are being stored on IBM’s cloud computers, for Walmart’s use. That has led to questions about why a distributed database like a blockchain is even necessary.

  3. Blockchain math is actually rather useful, to the extent that it is a (digitally signed) "chain of blocks," which was revolutionary long ago, when it was first conceived. As one example, git is a chain of blocks and many of its magical properties come directly from that. Chains of blocks are great.

Peeking Behind the Curtains of Serverless Platforms Some highlights from this study:

  • AWS Lambda achieved the best scalability and the lowest coldstart latency, followed by GCF. But the lack of performance isolation is noted.
  • GCF, only about half of the expected number of instances could be launched at the same time.
  • AWS launched new instances of the outdated function (2% of all the cases). We found zero cases with a 6-second waiting time.
  • Azure vulnerability: a tenant can arrange for function to run on same VM as another tenant, stepping stone to side-channel attacks.

Notes to myself on software engineering Fantastic stuff. Go read, bookmark for later, share with your team:

  1. The most powerful mental models are modular and hierarchical: simple at a high level, yet precise as you need to go into details. In the same way, a good API is modular and hierarchical: easy to approach, yet expressive. There is a balance to strike between having complex signatures on fewer objects, and having more objects with simpler signatures. A good API has a reasonable number of objects, with reasonably simple signatures.

If performance at one level of a hierarchy is uncorrelated with performance at the next level up, the best strategy is simply to promote the very worst people.

Design Objective

Patrick Thornton This should be common knowledge:

Designers are usually given symptoms, not actual problems to solve.

First step is to figure out the real problem that needs to be solved.

This means that product managers, journalists, business people, etc. need to understand this first step. They usually get problem wrong.


Ryan Singer Because if you don't understand the problem, the solution will eat your product alive:

A major cause of product bloat is building things you know how to build but don't understand. If a customer wants it, but it doesn't fit into your mental model of use cases, building it creates an area in the system that you can't reason about.

My Favorite Sayings 💯

The greatest performance improvement of all is when a system goes from not-working to working … The real challenges are getting programs completed quickly, ensuring their quality, and managing the complexity of large applications. Thus the primary design criterion for software should be simplicity, not speed.

John Feminella What's easy to measure is not necessarily what you need to optimize:

Whenever I see a company hyper-focused on optimizing their infrastructure pennies, I wonder how many dollars are being missed elsewhere in the pipeline.

📜 Here's a thread of one example of what I mean by this.

The subtleties of API contracts, or how enabling HTTP/2 broke Go clients API contracts are not just function name and argument types (h/t drewish):

Go had previously not defined whether it was safe to reuse a request, but it was. Go 1.6 still didn’t define whether it was safe to reuse a request, but it wasn’t, and in the meantime users started to implicitly depend on the behavior. The slight shift in contract is about as subtle as things get, but it was a change in contract nonetheless, and demonstrates how it’s possible to introduce a breaking change even if every function signature stays the same.

Bruce Hauman Or as they say, "pro tip":

It happens far too often that the process of documenting a feature after its been implemented reveals serious flaws the design of that feature. I’m just not learning the obvious lesson.

I feel like I need this to pop up every time I go to post online.

Autism from the inside Too many depictions of autistic people rely on tired clichés. Listening and learning.

Danielle Paquette That's the right move:

Interesting: Microsoft announces it will only ink contracts with companies that provide workers 12 weeks of paid maternity/paternity leave.

That includes firms that staff landscapers, janitors and cafeteria workers:


Franken-algorithms: the deadly consequences of unpredictable code I guess we humans will learn the lessons the hard way:

In an algorithmic environment, many unexpected outcomes may not have been foreseeable to humans – a feature with the potential to become a scoundrel’s charter, in which deliberate obfuscation becomes at once easier and more rewarding. Pharmaceutical companies have benefited from the cover of complexity for years (see the case of Thalidomide), but here the consequences could be both greater and harder to reverse.

My mom, staying in my guest room, texted me to ask why it sounds like there's a fax machine stuck behind the wall. I told her it was the 3d printer running in the basement. We selected a weird future.

The Untold Story of NotPetya, the Most Devastating Cyberattack in History In which Russia uses code leaked from the NSA to craft a vicious malware, attack Ukrain and in the process cause $10 billion damages to various businesses around the world, including Russia's own Rosneft:

Then, in June 2017, the saboteurs used that back door to release a piece of malware called NotPetya, their most vicious cyberweapon yet.

The code that the hackers pushed out was honed to spread automatically, rapidly, and indiscriminately. “To date, it was simply the fastest-propagating piece of malware we’ve ever seen,” says Craig Williams, director of outreach at Cisco’s Talos division, one of the first security companies to reverse engineer and analyze NotPetya. “By the second you saw it, your data center was already gone.”

Why did they call it "Airbnb" when they could have called it "localhost"?

Anarkingu Gidora Use case:


fervour with measure Emoji, fancy unicode, and accessibility:

  • always add descriptions to images, so screen-reading users know what they're about. include what the key info is (e.g. what food it is, description of yr face and mood if it's a selfie)
  • use normal/custom emoji if you want, but sparingly
  • avoid spelling whole words with the letter emojis.

To Heal Some Wounds, Adult Cells Turn More Fetal Not just stem cells:

In a newly discovered type of wound healing, which some researchers call “paligenosis,” adult cells revert to a more fetal state.

Mr. Roger Live and let toast:

Could we, without relentlessly criticizing, let people have their pumpkin spice, and avacado toast, and their fandoms, and their D&D, and their too-early-Halloween-decorations, and whatever little harmless things in which they’ve manage to find a tiny shriveled flower of joy?

This is how Utah stocks fish in its mountain lakes. Utah's Department of Natural Resources says air drops are less stressful for the fish than a long journey by ground. More than 95% survive the fall. Utah DNR compares the fish to high divers diving into a deep pool of water. 🐟

I really feel like people aren’t taking the Republican PR campaign against perceived bias in tech companies anywhere near serious enough.
