sebiw··on Heroku: PostgreSQL Public Certificates Beta
Finally, no longer are MITM attacks between dynos and Heroku Postgres possible. :-)
sebiw··on Assassination of Boris Nemtsov
I can highly recommend the TV series "Putin – A Russian Spy Story" for people interested in how Putin came to power and some of the "unanswered questions" along that way.
sebiw··on Ask HN: How do you get out of a rut?
Leaving your usual context (work setting) and maybe getting some fresh air while doing so worked for me. Buying a bicycle and regularly taking some short-ish tours around my neighbourhood/city feels really nice.
sebiw··on Issue with TLS-ALPN-01 Validation Method
I understand your pain. Maybe keep in mind what operation they are running (complexity and scale) and that feedback may take time to implement. To put this into perspective think about what replacing certificates (or say obtaining new certificates) felt like before Let's Encrypt an ACME were a thing. ;-)
sebiw··on LetsEncrypt Certificate Issuance Halted
This is why most Let's Encrypt clients start renewal some x days before certificate expiration. 'Sall good. ;-)
sebiw··on Ruby 3.1.0 Preview 1
You can call `RubyVM::YJIT.enabled?` to check.
sebiw··on Some new BMWs won't have touchscreens thanks to chip shortage
I own a 7 series that has both, touch controls and the iDrive knob with physical controls. I mostly use the physical controls because BMW's user interface works quite nice with it and the physical controls are positioned where the driver's arm is resting, making it kind of natural to use. Touchscreen requires more leaning towards the screen, making it impractical to use while driving (of course, always be cautious while interacting with your infotainment while driving).
sebiw··on Notice of Stolen EVGA GeForce RTX 30-Series Graphics Cards
To be clear: I do not support theft and law enforcement must follow up on the offenders, recover what's left and seize the assets. But I just think a lot of people won't receive the message about these stolen cards and will be left with a rather shitty situation.
sebiw··on Python interpreter written in rust reaches 10000 commits
Didn't know, thanks!
sebiw··on Notice of Stolen EVGA GeForce RTX 30-Series Graphics Cards
I call this a dick move on EVGA's side, mainly harming consumers. I'm pretty certain they have insurance for incidents of this kind (theft), limiting the financial impact for them.
sebiw··on Python interpreter written in rust reaches 10000 commits
Technically speaking, Rust is a compiled language, which means an interpreter won't do the job.
sebiw··on Firefox 94
> With 94, you’ll find a selection of six fun seasonal Colorways (available for a limited time only).

For a limited time only? What the heck? Feels like Starbucks.

Otherwise great release of course.

sebiw··on Ask HN: Solo-preneurs, how do you DevOps to save time?
> Using this setup I can tear down and build up my setup in minutes [...]

Until you decide to move away from AWS. ;-)

Nevermind, ignoring the potential lock-in there are many pros to this setup.

sebiw··on Ask HN: Solo-preneurs, how do you DevOps to save time?
Heroku Postgres – after all those years – still is vulnerable to MITM attacks. You can't reliably verify the authenticity of the connection between Heroku's Dyno and the Postgres database.

They use self-signed certificates on Heroku Postgres servers without a certificate authority present in the chain. No chance to establish reliable peer verification. A shame, I would love to use Heroku more often without compromising security.

sebiw··on Apple Delays Rollout of Child Safety Features
Huh, I never really thought about the possibility that Apple would implement both schemes. I don't think they will go down that path, though. Why: Cost and complexity for Apple would be somewhat higher and the surrounding discussion about capabilities (abuse of the client-side system for other things than CSAM scanning) would persist just because of the existence of client-side scanning. Let's see how this story continues.
sebiw··on Apple Delays Rollout of Child Safety Features
What do you think are the chances we'll see a server-side implementation instead of the so far proposed client-side one?
sebiw··on U.S. and key allies accuse China of Microsoft Exchange cyberattacks
"Simply stated, there is no doubt that Saddam Hussein now has weapons of mass destruction." — Dick Cheney, before the US and coalition of the willing invaded Iraq.
sebiw··on Ask HN: Favorite purchases of last two years?
Bose QC35 II noise-cancelling headphones.

Being able to decouple yourself from noise is worth so much more than what Bose is asking for these headphones.

sebiw··on The Exclusive Website
Nginx can, most backends can‘t. ;-)
sebiw··on Homebrew 3.0
Dear Homebrew maintainers,

one simple effing thing: thank you! For all the hard work and the sheer pleasure Homebrew adds to the experience of developing software on a Mac.

sebiw··on Ruby 3.0
I just wanna say thank you to all people who behind the scenes keep evolving Ruby as a programming language!

I was at the edge of giving up on programming some long time ago and Ruby drove back a lot of my passion for creating things.

Ruby 3 is yet another great release (Ractor for parallelism for example). Can't wait to see what 3.1 will bring.

sebiw··on Start with pen and paper
I found this book by the team of Basecamp (DHH et al) really inspiring: https://basecamp.com/books/getting-real
sebiw··on Fedora 33
I am running Btrfs on about a dozen machines (solid state and spinning disks). All of them are servers and run "business-critical" stuff. No issues during the last 2 years, everything flawless.

The ability to scrub your data and have strong data integrity guarantees is just one of the benefits of Btrfs. I'm also using transparent compression (GZIP and ZSTD) and even RAID1 (disk replacement procedure worked flawless last time I had to use it).

For workloads such as MariaDB (heavily updated-in-place files) you may want to go ahead and disable CoW features, though. This leaves you without data checksumming (InnoDB uses it's own checksumming - not losing much there) but you still get a lot of the other great Btrfs features.

sebiw··on Y Combinator has lost its soul: A YC founder's perspective
I understand what you say and I assume you have more experience than me in this field.

But even if you fail, that's experience too. If you have a dream, I strongly encourage you to pursue it. It is usually more painful to look back in hindsight and one day wake up to a reality where you never even tried.

To whoever is reading this: Try. Then try again. Then try another. And don't forget to look after yourself and your loved ones.

sebiw··on Apple announces it will switch to its own processors for future Macs
Will I still be able to use my favourite scripting language, say Ruby, on macOS?
sebiw··on AI Clones Your Voice After Listening for 5 Seconds (2018)
Anybody else thinking about the scene from the Bourne trilogy where Jason opens Noah Vosens safe using a voice sample he took of him on the phone?
sebiw··on FreeBSD 12.1
Been running Linux servers for years. FreeBSD is what gave me back the passion to run servers.

It's such a well structured operating system. The documentation is just great and Jails are a really nice way to get lightly isolated environments to run different web services.

Thanks to all the people who make FreeBSD possible!

sebiw··on What’s New in Apple Filesystems [pdf]
What physical medium do you use (HDD, SSD)? I had a faulty HDD act up on me like that.
sebiw··on What’s New in Apple Filesystems [pdf]
According to the file's meta information, the content was created using Keynote and then converted using macOS Quartz PDF.
sebiw··on What’s New in Apple Filesystems [pdf]
Initially only found the PDF, then saw the video link at the end.
