Tech Debt: The Bill Comes Due by Adam Coster: if we don’t solve the problems of our past, the futures that we want become ever more difficult to obtain. That’s true in life, and it’s true in software. In life, the past comes in the form of baggage. In software, we call that “technical debt”. For both life and software, how do you deal with the past? Do you ignore it and hope for the best? Do you continuously make your future better, via therapy and code refactoring? Do you cut ties with the past completely, via moving to another city and starting a new git repository?
The RIAA, GitHub, and youtube-dl by Jake Edge: toward the end of October, GitHub removed the repository for the youtube-dl utility, which provides a means to download video content from various streaming sites, such as YouTube. The repository was replaced with a cheery notice that it had been removed due to a DMCA takedown.
CircleCI Report Finds DevOps Teams Adjusting to New COVID-19 Normal by Mike Vizard: an annual State of Software Delivery report published today by CircleCI suggests that after a spike in developer activity last spring at the beginning of the COVID-19 pandemic, the pace at which code is moving through a continuous integration/continuous delivery (CI/CD) platform has returned to normal levels even as developers continue to work from home.
What I Learned From Bombing a Technical Interview by Ceora Ford: so… I embarrassingly bombed a technical interview yesterday. It was… BAD.

The world needs women who code by Seema Saharan: how can we motivate more women to get into the technology field?
Millions of Remote Workers Are Now Thinking About Moving by David Cassel: because of remote working, millions of teleworkers are now thinking about moving, according to a new survey by the freelancing platform Upwork.

Travis CI’s new pricing plan threw a wrench in my open source works by Jeff Geerling: I just spent the past 6 hours migrating some of my open source projects from Travis CI to GitHub Actions, and I thought I’d pause for a bit (12 hours into this project, probably 15-20 more to go) to jot down a few thoughts.
- Announcing HashiCorp Vault 1.6: in this release, we added enhancements to Integrated Storage, added the ability of tokenizing sensitive data to the Transform Secrets Engine, made web UI improvements and added a new Key Management Secret Engine.
- Keeping Netflix Reliable Using Prioritized Load Shedding by Manuel Correa: in Netflix engineering, we’re driven by ensuring Netflix is there when you need it to be. Yet, as recent as last year, our systems were susceptible to metaphorical traffic jams; we had on/off circuit breakers, but no progressive way to shed load. Motivated by improving the lives of our members, we’ve introduced priority-based progressive load shedding.

Terraform 0.14 Adds a New Concise Diff Format to Terraform Plans by Alisdair McDiarmid: the upcoming HashiCorp Terraform 0.14 release includes a new, experimental, on-by-default, concise diff renderer.

- Why Paying to Delete Stolen Data is Bonkers by Brian Krebs: companies hit by ransomware often face a dual threat: Even if they avoid paying the ransom and can restore things from scratch, about half the time the attackers also threaten to release sensitive stolen data unless the victim pays for a promise to have the data deleted. Well, new research suggests a fair number of victims who do pay up may see some or all of the stolen data published anyway.
- IAM whatever you say IAM by Alex Chantavy: using graphs helps us visualize and reason about security problems in a very powerful way. One such problem is understanding cloud permissions relationships: we needed an answer to the question “who has permission to read and write to my sensitive data resources?” In the cloud, this is not always a straightforward problem!
twilio-npm) opens backdoors to let attackers access infected workstations.
Ok Google: please publish your DKIM secret keys by Matthew Green: every now and then, however, a major Internet company finds a solution that actually makes the situation worse for just about everyone. This post is about the situation with Domain Keys Identified Mail (DKIM), a harmless little spam protocol that has somehow become a monster.
- PyPy: Faster Python With Minimal Effort by Jahongir Rahmonov: Python is one of the most popular programming languages among developers, but it has certain limitations. For example, depending on the application, it can be up to 100 times as slow as some lower-level languages. That’s why many companies rewrite their applications in another language once Python’s speed becomes a bottleneck for users. But what if there was a way to keep Python’s awesome features and improve its speed? Enter PyPy.

scpby Jonathan Corbet: the
scpcommand, which uses the SSH protocol to copy files between machines, is deeply wired into the fingers of many Linux users and developers. Many users may be surprised to learn, though, that the resemblance to
rcpgoes beyond the name; much of the underlying protocol is the same as well. That protocol is showing its age, and the OpenSSH community has considered it deprecated for a while.

CloudFormation adds support for arbitrary bash commands by Craig Lefkowitz and Shantanu Gupta: oftentimes we find customers who want to extend their AWS CloudFormation templates by running a few lines of code during template execution. For example, to call an external API. In these cases, customers were directed to use either custom resources, resource types, or macros to accomplish the task. This is such a common pattern that we decided to write the CommandRunner resource type that helped customers to quickly develop bash scripts that run during the execution of AWS CloudFormation templates.
Advice for customers dealing with Docker Hub rate limits, and a Coming Soon announcement by Omar Paul & Michael Hausenblas: with the introduction of Docker Hub’s new rate limits, our customers should expect some of their applications and tools that use public images from Docker Hub to face throttling errors, such as when they build from a parent public image or pull a public image to run.
