xer | 4 days ago | on: AWS outage due to drone attacks in UAE

Lesson learned: If your recovery plan requires calling any API in the dead region — to detach an IP, describe a route table, launch an instance, read an S3 object, or decrypt a volume — it will fail when you need it most.

Every dependency on the primary region is a dependency on the thing that just broke.

xer | 2 years ago | on: Removing data transfer fees when moving off Google Cloud

I share the view that nobody avoids an exit or migration because of egress fees. In fact, for online migrations the period of replicating data between providers might go on for months.

But all cloud providers leverage The Principle of data locality or data gravity, which states that compute benefits from being close to the stored data. If a customer moves the data elsewhere it follows that the compute will soon leave too.

The elephant in the room: Will Spotify survive the coming wave of generative AI audio content? Wasn't any mentioning on that in the letter.

Seems to me like they would need to ditch a lot of silly investments like original content, platform engineering on Kubernetes and scaled agile which together carry costs in the range of $100s millions, to free up resources to battle new disruptive technologies.

Correct. It's also the case that human generated requests will lose their relevance within seconds, a quick retry is all it's worth. As for machine generated requests a dead letter queue would make more sense, poor engineered backend services would OOM and well-engineered would load shed, if the requests are queued on the application servers they are doomed to be lost anyway.

xer | 5 years ago | on: My Google Traffic Has Fallen to Zero

I think there is another side to this story which is that referral marketing is having a bad name these days. It's considered fraudulent by many sellers since sometimes these referral sites rank higher than the sellers themselves. I suspect this is part of an effort from Google to put the sellers higher than the referrers in the search results.

xer | 8 years ago | on: The Role of Luck in Life Is Still Misunderstood

From my experience you can increase your luck in life by exposing yourself to more choices. This can be something as simple as having saved up money so you can quit your job whenever you want to. That in turn gives you the "luck" to get a better job if the opportunity presents itself.

xer | 8 years ago | on: Why and how the Cryptobubble will burst

Bubbles are everywhere, one you probably never heard of is called humanity, yes our species.

One significant fuel of blockchain tech is the distrust in the current financial systems. If central bankers and governments could regain trust there is a probable chance of a bust.

xer | 8 years ago | on: Ask HN: How was your experience with AWS Lambda in production?

At Annsec we are all out on serverless infrastructure and use Lambdas and Step functions in two development teams on a single backlog. Extensibility of a well written lambda is fenomenal. For instance we have higher abstraction lambdas for moving data. We make them handle several input events and to the greatest extent as pure as possible. Composing these lambdas later in Step functions is true developer joy. We unit test them locally and for E2E-tests we have a full clone of our environment. In total we build and manage around 40 lambdas and 10 step functions. Monitoring for failure is conducted using Cloudwatch alarms, Ops Genie and Slack bots. Never been an issue. In our setup we are aiming for an infrastructure that is immutable and cryptological verifiable. It turned out to be bit of a challenge. :)
