onefuncman··on Accounting For Developers, Part I
> conceptual meaning consistent across all accounts.

Except programmers quite often get the conceptual meaning wrong and incorrectly generalize further. Credit and debit just mean increase or decrease in account balance. You cannot know how it affects liabilities or assets without knowing what type of account is being modified.

> When an account is CREDITED, this always represents an increase in liabilities[0] (or equivalently, a decrease in assets).

> When an account is DEBITED, this always represents an increase in assets (or equivalently, a decrease in liabilities).

This is where you're wrong. You can credit and debit Accounts Payable and Accounts Receivable. If you credit AP, you're increasing liability, if you credit AR, you're increasing assets.

onefuncman··on Botspam apocalypse
I want to run a honeypot for doing more research on bots and the economics for them, but I get bogged down quickly in the planning stages. I should just start with a vulnerable wordpress site or something.
onefuncman··on Alpine Linux is reducing dependencies on Busybox
My golden rule of sys admin is if you can't fix it, you reformat and replace it.

If you reproduce the error, congrats, now you get to figure out where to file the bug report with reproduction steps.

Whoops! As a result of your action, your userbase has now hyperfixated on follower counts as a proxy for status.

onefuncman··on We’re the founders of Substack, we just launched an iOS app. AUA
A few (but not too many) years ago I inherited a custom compilation of python2.x to make unicode strings work properly. You made the right call, lol.
onefuncman··on The new White House memo on zero trust is a strong signal
You're missing the point. There is no internal network in this new model.
onefuncman··on Pfizer board member suggests end to mask, vaccine mandates
This didn't happen all of a sudden in Sept 2021. The flu vaccine has always been about harm reduction and began seeing widespread civilian use in 2007-2008.

onefuncman··on Pelosi defends stock trading by lawmakers. ‘We are a free-market economy’
It's actually not. Any product making medical claims is regulated by the FTC under deceptive advertising. https://www.ftc.gov/enforcement/statutes/federal-trade-commi...

> maybe this has improved?

Yes, you can recover a Cloudformation stack from any status nowadays. Ex: https://aws.amazon.com/premiumsupport/knowledge-center/cloud...

onefuncman··on Security issue related to the NPM registry
are you really using private keys without a passphrase in 2021?
onefuncman··on How to build a second brain as a software developer
I go back and forth between doing this on a daily or weekly cadence, but it's also the only thing I've found to keep being useful over time. I always get a wild hair to try and write Markdown or something but really I just end up writing text and it's fine. The most meta I ever get is adding additional keywords for me to search later.
onefuncman··on Grand jury subpoena for Signal user data, Central District of California
Shouldn't Signal be required to produce all the encrypted data stored for this user, in case law enforcement are able to get the associated private keys off the suspect's phone?
onefuncman··on Show HN: Visualizing a Codebase
I used Gource to visualize a hackathon, we had everyone start from a templated repo so it was really easy to show the entirety of participants coding activity (albeit at a macro level)
onefuncman··on How I store my files
I put my 1Password vault on Dropbox specifically because I can install both apps via iOS store on a new phone and bootstrap my setup with just 2 passwords.

iCloud is actually too hard to recover in case of hardware loss, I don't recommend it to anyone.

onefuncman··on Good Riddance, TurboTax. Americans Need a Real ‘Free File’ Program
This is run by Intuit (and requires the www, https://www.freefilefillableforms.com/ )

Looks like their AppDynamics RUM js config is leaking their internal hostnames in the page source too.

onefuncman··on Generating JSON Directly from Postgres
that's what a Schema Registry is for... protobuf is a little more polished around managing forwards and backwards compatibility than avro but they both work.
onefuncman··on Ask HN: How do you manage forearm/wrist pain?
At the first sign of any pain I try to identify the cause. It's almost always ergonomic related.

The most useful stretch/exercise I do is pushing my hands together, palms flat against each other, in front of my sternum with my fingers pointing up, out, and down for ~30 seconds in each position, once or twice a day.

I am in exactly this situation (but at the days/weeks timescale instead of months), so thanks for posting how you resolved this, I'll try my local IRS office.
onefuncman··on A serverless email server on AWS using S3 and SES
The Lambda doesn't send or receive email directly, it uses SES.

SES handles this in a delegated way via DKIM signatures (Domain Keys Identified Mail).

It makes complete sense from a programmer's point of view. Refactor the relationship by deleting the troublesome elements, leaving behind what you want to keep.
onefuncman··on Slack is down
It's easy to fall behind on bumping up the high watermark for your max autoscaling or for new traffic patterns to cause emergent instability. New code paths are taking unprecedented amounts of traffic all the time.

In 2021, how does one keep track of resource starvation at the process, container, os, service, pod, cluster, availability zone and region levels?

onefuncman··on Load testing is hard and the tools are not great
the adage from service level perf testing (you don't know what's really slow/brittle until you measure...) holds equally well at the systems level. Yes, you can probably identify decent areas to improve by guessing, but you'll never find your blind spots...
onefuncman··on Kafka Is Not a Database
this isn't any different than microservices getting a deathball dependency on a user service or logging service or security service or ...

you either don't allow microservices to consume from others' topics, or you publish event schemas so they can still iterate independently.

the move to a 2nd kafka cluster in my experience has always been driven by isolation and fault tolerance concerns, not scalability.
