1. One company’s plan to build a search engine Google can’t beat

One

You can’t out-Google Google. For two decades, companies have tried to build a better search engine, and now the internet graveyard is filled with would-be competitors. Even the smash successes only get to 1% or 2% market share.


2. Access Token Lifetime

When your service issues access tokens, you’ll need to make some decisions as to how long you want the tokens to last. Unfortunately there is no blanket solution for every service.


3. Doing Stupid Stuff with GitHub Actions

TL;DR: DevOps doesn’t have to be all work and no play. I built 5 stupid (but fun!) GitHub actions… because why not? The full code for these actions can all be found in this GitHub repo. I encourage you to fork and/or add issues/PRs with impractical actions of your own!


4. Weekly To-do

Kubernetes Blog Post in Chinese Coding for MMSS


5. I Am a Model and I Know That Artificial Intelligence Will Eventually Take My Job

I

Shudu Gram is a striking South African model. She’s what fashion likes to call “one to watch,” with a Balmain campaign in 2018, a feature in Vogue Australia on changing the face of fashion, and a red carpet appearance at the 2019 BAFTAs in a custom Swarovski gown. I’m also a model.


6. Running high-scale web applications on Amazon EC2 Spot Instances

Running

At re:Invent in 2017, AWS made some significant changes to the pricing model of Amazon EC2 Spot Instances. Instead of bidding on spare capacity, you could request to run Spot Instances, and get the capacity if it’s available.


8. Designing scalable API on AWS spot instances

Designing

Our backend system is built on AWS. Today I’m going to tell you how we had cut costs three times for the servers by using spot instances on the production environment. I’ll also walk you through configuring auto scaling.


9. What I learned after reviewing over 40 developer portfolios – 9 tips for a better portfolio

What

When I started developing websites about ten years ago, one of the hardest things was to get someone else’s opinion for my pages. That’s why decided to give back to the community by critically reviewing their portfolios. I took a look at things like


10. Machine Learning for a Better Developer Experience

Machine

Imagine having to go through 2.5GB of log entries from a failed software build — 3 million lines — to search for a bug or a regression that happened on line 1M.


11. Monitoring your own infrastructure using Grafana, InfluxDB, and CollectD

Monitoring

For some companies, infrastructure is the heart of its business. Specifically, I am referring to those companies which need to manage data and applications located on more than one server.


12. Write Like You Talk

Here’s a simple trick for getting more people to read what you write: write in spoken language. Something comes over most people when they start writing. They write in a different language than they’d use if they were talking to a friend. The sentence structure and even the words are different.


13. Build a Toy Quantum Computer at Home

In the past few posts we’ve gone over how to interpret matrices, basis vectors, and eigenvectors.


14. It’s time to start writing

I recently became aware of Jeff Bezos’s dotcom-era policy of banning PowerPoint within Amazon.


15. Six Ways to Think Long-term: A Cognitive Toolkit for Good Ancestors

Six

Human beings have an astonishing evolutionary gift: agile imaginations that can shift in an instant from thinking on a scale of seconds to a scale of years or even centuries. Our minds constantly dance across multiple time horizons.


16. The FBI Is Secretly Using A $2 Billion Company For Global Travel Surveillance — The US Could Do The Same To Track Covid-19

The

American border patrol already has significant surveillance powers and collects vast amounts of data on who is flying into and out of the country. But the U.S. has another tool to watch over travellers across the world thanks to a little-known but influential Texan business called Sabre.


17. Coronavirus: Oxford vaccine triggers immune response

Coronavirus:

Trials involving 1,077 people showed the injection led to them making antibodies and T-cells that can fight coronavirus. The findings are hugely promising, but it is still too soon to know if this is enough to offer protection and larger trials are under way.


18. 22 Principles for Great Product Managers

Edit 07.20.20: This post was #1 on Hacker News today, which did 2 things: First, it crashed this site (sorry, won’t happen again). Second, it catalyzed some great dialogue here. If you’d like to continue the conversation, hit me up on Twitter.


20. Robinhood and How to Lose Money

Robinhood

Ranjan here. Today I’m writing on Robinhood, what investing means to me, and whether you should be trading options. For someone who clearly has strong opinions they enjoy communicating with others, investing occupies a weird place for me.

22. Differences between Node and the Browser

Differences

Both the browser and Node use JavaScript as their programming language. Building apps that runs the browser is a completely different things than building a Node.js application.


26. Content Security Policy (CSP) in Create-React-App (CRA)

Content

Writing suitable CSP policy may requires some changes to your app build pipeline to fetch and calculate hashes for inline scripts and styles, which are used. CRA is one of the build tools which I am using in different projects.


27. Algorithms Specialization

Algorithms

“),a.close(),s=a.F;n–;)delete s.prototype[r[n]];return s()};module.exports=Object.create||function create(e,r){var a;return null!==e?(o.prototype=t(e),a=new o,o.prototype=null,a[i]=e):a=s(),void 0===r?a:n(a,r)}},rBzQ:function(module,exports,e){“use strict”;Object.


30. A Guide to Experience Mapping for UX Design

A

A user experience map is a method of visualizing the entire end-to-end user experience that an average user will go through in order to accomplish a goal. It’s product and service agnostic, so it’s used for understanding general human behavior in a larger context.


31. Why Stripe Gave Up on Bitcoin and Blockchain Payments

Why

In 2015, digital payments giant Stripe unveiled a tool for merchants around the world to accept Bitcoin. At the time, Stripe’s news came as further evidence that a cryptocurrency revolution was underway. But this April, Stripe pulled the plug.


32. Async OOP 2: Constructors

Asynchronous construction poses an interesting problem. It would be useful to be able to use await in a constructor, but this would mean that the constructor would have to return a Task representing a value that will be constructed in the future, instead of a constructed value.


33. When Not To Use YouTube or Vimeo For Hosting Business Videos

When

Today’s businesses are increasingly using video to share all types of internal and external information.


34. How to speed up building Docker images

How

Below we break down each of them into a separate paragraph with some essential info that will help you deliver well-optimized lightweight images and use them in your delivery process. To put it simply: every time a new line is executed in the Dockerfile, a new Docker layer is created.


35. Difference between dependencies, devDependencies and peerDependencies in npm

When creating a new npm project, all those with a package.json in the root directory, we usually don’t create everything from scratch but need some dependencies. There are different type of dependencies that can be somewhat difficult to keep apart.


36. Pattern: Saga

Pattern:

You have applied the Database per Service pattern. Each service has its own database. Some business transactions, however, span multiple service so you need a mechanism to ensure data consistency across services.


37. Saga Pattern | Application transactions using Microservices – Part I

Saga

Transactions are an essential part of applications. Without them, it would be impossible to maintain data consistency. One of the most powerful types of transactions is called a Two-Phase Commit, which is in summary when the commit of a first transactions depends on the completion of a second.


38. Building Cloudflare TV from scratch

Building

Cloudflare TV is inspired by television shows of the 90s that shared the newest, most exciting developments in computing and music videos. We had three basic requirements for Cloudflare TV:


39. Show & tell: a steampunk desktop background radiation monitor

Show

I was always a fan of the steampunk style, and having also had experience building steam engines in the past, there was only one real direction this project could go.


40. Building Domain Driven Microservices

Building

The term ‘micro’ in Microservices, though indicative of the size of a service, is not the only criteria that make an application a Microservice. When teams move to a microservices-based architecture, they aim to increase their agility — deploy features autonomously and frequently.


41. Parallel computing in ReactJS

Parallel

Vue.js is an extensively popular JavaScript framework with which you can create powerful as well as interactive interfaces. Vue.js is the best framework when it comes to building a single web and mobile apps.


42. On Moving from Statistics to Machine Learning, the Final Stage of Grief

On

I’ve spent the last few months preparing for and applying for data science jobs. It’s possible the data science world may reject me and my lack of both experience and a credential above a bachelors degree, in which case I’ll do something else.


43. OpenStreetMap, a global map for worldwide insight

OpenStreetMap,

OpenStreetMap improves every day. Its unparalleled global coverage — from roads and rivers to pharmacies, forests, and much more — makes OpenStreetMap a vital resource for building high-quality visual maps and navigation services for every part of the world.


44. Micro Frontends

Micro

Good frontend development is hard. Scaling frontend development so that many teams can work simultaneously on a large and complex product is even harder.


48. The end of the Redis adventure

When I started the Redis project more than ten years ago I was in one of the most exciting moments of my career. My co-founder and I had successfully launched two of the major web 2.0 services of the Italian web.


49. Worrying about the NPM ecosystem

There are too many packages and too many dependencies, too deeply nested. Can we measure the problem? And what do we do about it? The npm ecosystem seems unwell.


50. The 25 greatest Java apps ever written

The

The story of Java began in 1991, at a time when Sun Microsystems sought to extend their lead in the computer workstation market into the burgeoning personal electronics market.


51. Do call yourself a programmer, and other career advice

This is a (very late) reply to Patrick McKenzie’s “Don’t Call Yourself A Programmer, And Other Career Advice”.


52. India bans TikTok, dozens of other Chinese apps

India

The Indian government on Monday evening said it was banning 59 apps developed by Chinese firms over concerns that these apps were engaging in activities that threatened “national security and defence of India, which ultimately impinges upon the sovereignty and integrity of India” in what is the


54. Why AnyList Won’t Be Supporting Sign In with Apple

Starting June 30th, Apple will be enforcing a new rule in the App Store requiring many apps to support Sign in with Apple. AnyList is one of the apps affected by this new rule, which means that we must either implement Sign in with Apple or make other changes to our app.


56. Your retro action items aren’t working. Here’s why.

Your

A retrospective is a time for our team to look back. Its function, however, is to improve the way in which we move forward. Let’s digest the original definition from Scrum:


57. Action Focused Retrospectives

Action

Action focused retrospectives are a way for your team to reflect on your past cycle of work, discuss what you’ve learned, identify specific action items to pursue, and follow through on those action items.


60. I Just Hit $100k/yr On GitHub Sponsors! 🎉❤️ (How I Did It)

My last year as a full-time developer (at Tighten) was 2018. (Read “On Leaving My Day Job” for that story) Developer salaries vary like crazy, but $90k was pretty solid for me. Combined with my wife’s income and some Mustachianism it was plenty to save up a chunk of cash for a rainy day.


61. Tensorflow on edge, or – Building a “smart” security camera with a Raspberry Pi

The amount of time my outdoor cameras are being set off by light, wind, cars, or anything other than a human is insane. Overly cautious security cameras might be a feature, but an annoying one at that.   Folks, meet what I lovingly call “Scarecrow-Cam”.


62. sokra/slides

64. Why 536 was ‘the worst year to be alive’

Why

Ask medieval historian Michael McCormick what year was the worst to be alive, and he’s got an answer: “536.” Not 1349, when the Black Death wiped out half of Europe. Not 1918, when the flu killed 50 million to 100 million people, mostly young adults. But 536.


67. GitHub isn’t fun anymore

GitHub

At first I thought it was just me getting older and more experienced. But after several conversations about it with colleagues and other open source maintainers, I’m not the only one who feels this way.


68. Why Gravity Is Not Like the Other Forces

Why

We asked four physicists why gravity stands out among the forces of nature. We got four different answers. Physicists have traced three of the four forces of nature — the electromagnetic force and the strong and weak nuclear forces — to their origins in quantum particles.


69. AWS’s Share of Amazon’s Profit

Wow, there is a lot to unpack here. Boring? Art? I said it’s boring because you keep writing code that looks like blocks and blocks of text having the same shape. Assignments, conditionals, loops, functions, etc.


76. PostgreSQL 12.3

PostgreSQL is a major open-source relational database with a 23-year history and a broad range of features. While Jepsen’s work has traditionally focused on distributed systems, our tooling is readily applicable to traditional, single-node databases.


77. Home Lab Beginners guide – Hardware

Home

Until recently, and for well over the past decade, my wife and I have been nomads. Moving from the Caribbean to Miami, New York, Las Vegas, Vancouver, and now back home. This has meant that for many of those years, my home office basically comprised of a few laptops and screens.
