just curious, what do you need SPIFEE workload identity for? I've used it in the past for building something like Tailscale
fierro··on The architecture behind a one-person tech startup
work on an infrastructure team. This is standard cloud infrastructure -- the networking (cloudflare/ingress LBs), k8s, terraform, CI/CD etc etc
fierro··on The architecture behind a one-person tech startup
yeah, this is the more sane approach. Just use Google's replication/durability, and export to S3 when you want/need to change vendors. In this case, you wouldn't even need lightstream. Just SQLite.
fierro··on Metis and Bodybuilders
The only reliable way to find truth in fitness and bodybuilding is to experiment for yourself and find what works for you given your genetics, diet, recovery regimen, and supplementation (including use of AAS) or lack thereof.
fierro··on Metis and Bodybuilders
the sentiment regarding steroid use is becoming less negative and stigmatic. A lot of older pros talk about it openly now (ex Dorian Yates) and a lot of current modern pros are openly disclosing their routines. Sponsors are becoming more tolerant of this as it's now as the honesty is now seen as cool and attracts an audience.
fierro··on Metis and Bodybuilders
it's not so much that it's contradictory, but rather dishonest. One example is that a lot of athletes hawking supplements are actually taking exogenous hormones and androgenic anabolic steroids and fail to mention this.

Also, it's in the interest of the online fitness community to make their advice as complex and complicated as possible as is re-entrenches their "expert" position while the truth tends to be much simpler, as your parent comment alluded to

I think this is a bit hand wavey. Being able to run workloads on the edge does not solve the data storage problem.

what is the Kappa architecture?
fierro··on Why is OOP still so widely spread?
I agree. This gets at the real distinction between one language and another; which patterns have been elevated to the status of a statement, expression, control structure, or keyword. class in Java is a formalization of the OOO pattern, for example.

There's nothing you can do with OOO that you can't without it, and vice-versa. At the end of the day all we have are instructions and data.

fierro··on Kubernetes: Make your services faster by removing CPU limits
note: if you truly are experiencing noisy neighbor effects when only using requests, it just means you need to adjust (increase) a request somewhere.
fierro··on Kubernetes: Make your services faster by removing CPU limits
the genesis of cfs_quota and cpu throttling in general has to do with modulating power consumption of a chip, iirc. It's truly a fallacy that limits are needed to prevent noisy neighbor type stuff.
fierro··on Kubernetes: Make your services faster by removing CPU limits
The core principle most readers miss is that CPU limits are tied to CPU throttling, which is markedly different than CPU time sharing. I would argue that in 99% of cases, you truly do not need or want limits.

limits cause CPU throttling, which is like running your process in a strobe light. If your quota period is 100ms, you might only be able to make progress for 10ms out of every 100ms period, regardless of whether or not there is CPU contention, just because you've exceeded your limit.

requests -> CFS time sharing. This ensures that out of a given period of time, CPU time is scheduled fairly and according to the request as a proportion of total request (it just so happens that the Kube scheduler won't schedule such that sum[requests] > capacity, but theoretically it could because requests are truly relative when it comes to how they are represented in cgroups)

Here is the fundamental assertion: requests ensure fair CPU scheduling in the event of CPU contention (more processes want CPU than can be scheduled). Given that you are using requests, why would you want limits? You might think "limits prevent a process from taking too much CPU" but that's just not true. If that processes DID try to use up too much CPU, CFS would ensure it does not via fair time sharing. If no other running processes needed the CPU, why enforce CPU throttling which has very bad effects on tail latency?

This does not seem like a sound philosophical security posture -- that only domains who are "massive targets for hacking" should use Registry Lock.
fierro··on Uber to quit Colombia after judge says it doesn’t compete fairly
True. There's also Picapp, with which you can hail a car or a moto, which is actually crazy and fun, and sometimes faster.
fierro··on Uber to quit Colombia after judge says it doesn’t compete fairly
Of any country I've visisted, Uber is the least necessary in Colombia. The taxi system is extremely fair and safe, albeit cash only right now. It's highly regulated and you can count on predictable, transparent, fair rates.

When I took an Uber at the Medellin airport, a guy saw me waiting at the curb and called my name, explaining that he would drive me to my actual Uber. I hopped in, and he drove me a mile or two outside the airport to a lot where all the real Ubers were waiting. We switched cars, and presumably he got some small kickback, then returned to the airport to smuggle people to their Uber. It was a pretty interesting experience; the police at the airport readily fine Ubers that pick up passengers and know the cars by license plate.

fierro··on Leak of Microsoft Salaries Shows Fight for Higher Compensation
helllll no this is 100% not true. I worked at Google, and there is an internal spreadsheet with compensation that is contributed to on a voluntary basis, and has n=1000+ for many levels. The variance is far greater than 5%.

*for Googlers, you can find this at go/salarycomp or something like that, I can't remember
