How to prevent developer burnout

Earlier this year, I led a joint research project between engineering productivity business Haystack Analytics and polling firm Survation, to understand the impact of burnout on developers. While there have been attempts to survey developer communities before, this represented the first time representative opinion polling was used to understand software engineers. When it came to burnout, the results were shocking. We found that 83% of software engineers reported that they were suffering from b

EngProd: The Secret of Elite Developer Teams

For companies to be successful, it is important to be able to get new ideas in front of users quickly, so you can keep up with the market and iterate based on real-world feedback. When technology teams find themselves unable to keep up with the pace of product development, they become the blockers of an organization. Ineffective technology leaders will pressure their developers to ship ever more work, causing developer burnout and software instability. By contrast, effective technology leaders

How Data Science Can Drive DevOps Growth - DZone DevOps

To improve, you must measure. Without measuring, you are left reading tea leaves with no understanding of whether you're closer, or further away, from your ultimate goal. Data provides the essential feedback to truly understand how well we're doing—indeed, it often surprises us. This concept is of fundamental importance for Engineering Managers and one I realized the importance of after reading The Goal by Eliyahu Goldratt. Indeed, as many successful organizations do, I had it as my main piece

North Korean Hackers Hide in Plain Sight | Hacker Noon

On the evening of the 25th January 2021, Google’s Threat Analysis Group published details of a campaign targeting security researchers attributed by them to “a government-backed entity based in North Korea”. Google described the attack as using a “novel social engineering method”. Social engineering usually describes attacks that target the human factors of computer security, such as by using phishing emails or phone call impersonation. Whilst highly-competent security experts may consider them

3 Software Ownership Models and Joint Care for Dev Teams | Hacker Noon

In traditional software operations, software would be "thrown over the fence" to operations teams. Technical operations teams would be aided in operating a service using Standard Operating Procedures (SOPs). With the advent of practices like DevOps and the growth in hiring SREs (Site Reliability Engineers), development and operations are increasingly unified. This has allowed "chore" work like deployments and maintenance to be automated. Standard Operating Procedures still play a role in this w

Using data science and machine learning for improved customer support

In this blog post we’ll explore three tricks that can be used for data science that helped us solve real problems for our customer support group and our customers. Two for natural language processing in a customer support context and one for identifying attack Internet attack traffic. Through these examples, we hope to demonstrate how invaluable data processing tricks, visualisations and tools can be before putting data into a machine learning algorithm. By refining data prior to processing, we

Project Crossbow: Lessons from Refactoring a Large-Scale Internal Tool

Cloudflare’s global network currently spans 200 cities in more than 90 countries. Engineers working in product, technical support and operations often need to be able to debug network issues from particular locations or individual servers. Crossbow is the internal tool for doing just this; allowing Cloudflare’s Technical Support Engineers to perform diagnostic activities from running commands (like traceroutes, cURL requests and DNS queries) to debugging product features and performance using b

Pwned Passwords Padding (ft. Lava Lamps and Workers)

The Pwned Passwords API (part of Troy Hunt’s Have I Been Pwned service) is used tens of millions of times each day, to alert users if their credentials are breached in a variety of online services, browser extensions and applications. Using Cloudflare, the API cached around 99% of requests, making it very efficient to run. From today, we are offering a new security advancement in the Pwned Passwords API - API clients can receive responses padded with random data. This exists to effectively prot

Banking-Grade Credential Stuffing: The Futility of Partial Password Validation

Recently when logging into one of my credit card providers, I was greeted by a familiar screen. After entering in my username, the service asked me to supply 3 random characters from my password to validate ownership of my account. It is increasingly common knowledge in the InfoSec community that this practice is the antithesis of, what we now understand to be, secure password management. For starters; sites prompting you for Partial Password Validation cannot store your passwords securely usi

Optimising Caching on Pwned Passwords (with Workers)

In February, Troy Hunt unveiled Pwned Passwords v2. Containing over half a billion real world leaked passwords, this database provides a vital tool for correcting the course of how the industry combats modern threats against password security. In supporting this project; I built a k-Anonymity model to add a layer of security to performed queries. This model allows for enhanced caching by mapping multiple leaked password hashes to a single hash prefix and additionally being performed in a determ

DNS-Over-TLS Built-In & Enforced - 1.1.1.1 and the GL.iNet GL-AR750S

GL.iNet GL-AR750S in black, same form-factor as the prior white GL.iNet GL-AR750. Credit card for comparison. Back in April, I wrote about how it was possible to modify a router to encrypt DNS queries over TLS using Cloudflare's 1.1.1.1 DNS Resolver. For this, I used the GL.iNet GL-AR750 because it was pre-installed with OpenWRT (LEDE). The folks at GL.iNet read that blog post and decided to bake DNS-Over-TLS support into their new router using the 1.1.1.1 resolver, they sent me one to take a l

What's Changed? Only running PHPUnit Tests for Changed Classes

Last night I was working on adding some features to a pretty large PHP project, the project had incredibly thorough Unit Testing. Whilst having too few Unit Tests is common issue for developers, in this case I was experiencing the exact opposite challenge; there were too many tests. The project had hundreds of thousands of Unit Tests (in some cases they really constituted Integration Tests) and it would take upwards of 40 minutes to run the entire test suite. After running a single change it si

To get around this problem, I borrow my friend's phone and dial the number - to protect my privacy I walk outside. When I'm done with the call, I come back inside and return the phone.

How Developers got Password Security so Wrong

Both in our real lives, and online, there are times where we need to authenticate ourselves - where we need to confirm we are who we say we are. This can be done using three things: • Something you know • Something you have • Something you are Passwords are an example of something you know; they were introduced in 1961 for computer authentication for a time-share computer in MIT. Shortly afterwards, a PhD researcher breached this system (by being able to simply download a list of unencrypted pa
