tbrock··on Turns out you won't be able to uninstall Windows 11's Recall feature after all
What windows laptop is that?
tbrock··on Xv6, a simple Unix-like teaching operating system

tbrock··on GDPR: Is It Worth It?
> but we need to remember enough that when we encounter you again, we recognize that you've objected to further processing. How are we supposed to know in future interactions that you've opted out if we've deleted all mentions of you and your PII?

Just hash the PII, delete the original and reinsert the hashed version (perhaps into another table). On insert check if hashes match and the opt out bit is set, if they match and it’s set then act appropriately.

tbrock··on France passes bill to allow police remotely activate phone camera, microphone
Or the manufacturers will just not sell their phones in France. Ultimately it’s the French citizens that will miss out.
tbrock··on Framework Laptop 16 Deep Dive – Memory and Storage
I like what framework is doing but boy is the 16” an ugly piece of hardware. The other one is beautiful, what happened?
tbrock··on Why does a plastic-wrapped turkey sandwich cost $15 at the NYC airport?
The bacon egg and cheese at Beecher’s handmade cheese in the same terminal is $16.50 for some decent bread with a microwave egg. It’s ridiculous, shake shack has a breakfast bacon egg and cheese in the $5-6 range right down the way.
tbrock··on Framework Laptop 16
I want framework to succeed and they are targeting folks who want sleek and customizable computers (which they’ve nailed) but compared to a thinkpad the build quality isn’t great.
tbrock··on ChatGPT Plugins
Too late, we spoke with someone on the team three years ago who told us he couldn’t help and we’ve moved on.
tbrock··on ChatGPT Plugins
And Zapier are unwilling to work with you to reduce that cost even at a scale of 1 billion requests per month.
tbrock··on ARM64 Linux Workstation
I really would like someone else to put out something competitive in that case, I’m rooting for them but haven’t seen it yet.
tbrock··on ARM64 Linux Workstation
A comparable m1 is twice as fast in the above benchmarks?

And that’s Apple’s chip from 2 years ago!

Core for core this is a dog.

tbrock··on ARM64 Linux Workstation
Performance isn’t there. Why spend 3k+ on this?
tbrock··on LED lighting badly suppresses human melatonin production at night
You can make the side button triple click on iPhone toggle application of an accessibility setting that lowers the brightness.
tbrock··on Building an ARM64 home server the hard way
You could do this for cheaper (and with more ram) using a raspberry pi 4 with a usb nvme ssd, it’s got gigabit ethernet and is arm64. Sure you have two less cores than this solution but it’s more likely to be supported over time and once you get the SD card out of the mix the I/O is solid. I’ve been surprised by how much the SD card throughput was limiting the experience.

I run arch Linux arm on mine and it’s a fantastic little device. I wonder if these boards are way faster or just more of the same. I guess the pcie expansion makes this more extensible.

tbrock··on Ask HN: What simple facts have you learned surprisingly late in life?
Why though? It would make more sense to keep lending at 2-ish% and making 8 in the market just throwing it in the S&P. The spread is 6 pts or more on average.
tbrock··on Just got offered office space in San Francisco (SOMA) for the same price as 2009
It’s 100% accurate for me having lived and worked in 3 neighborhoods over 7 years.
tbrock··on Tilck – A Tiny Linux-Compatible Kernel
If you’re learning, having a direct implementation vs multiple layers of abstraction is a huge benefit.
tbrock··on November 2022 Progress Report
Isn’t it more absurd that no vendors who support Linux make acceptable/comparable hardware?
tbrock··on Apple Reports Fourth Quarter Results
On android you’d be lucky to get more than a single OS update that added new features or functionality.
tbrock··on Linux M1 GPU driver passes 99% of the dEQP-GLES2 compliance tests
And better than any windows laptop on the market with the same performance profile.
tbrock··on Ask HN: What's Your Biggest Regret?
My dad started writing me letters after major life events and birthdays, on new years, etc... I save them all.

They boil down to advice like being grateful for what you have, looking back and being proud at what you’ve accomplished, valuing the people in your life especially those that take time to help you, and realizing how lucky you are and at the same time encouraging working to put yourself in positions where you make your own luck.

They seem to come at the right time, after I have a phone conversation when I tell him I’ve failed at something or am frustrated with someone.

It’s less about him and more about me but it helps me remember the kind of man he was, one of the greats.

tbrock··on Native Linux GPU Driver for Apple M1
This is so technically cool and an amazing achievement but wow what an odd video.
tbrock··on Go runtime: 4 years later
I am not a fan of new knobs like this. It reminds me of Java where you actually have to think about -xMx blah blah and setting it is a dark art. I would really prefer if we could somehow confer the memory limit from the container environment to go so this could be set intuitively at the container level without mucking about in the go GC internals.
tbrock··on Measuring CPU core-to-core latency
Would love to see what the results are for an m2.
tbrock··on Apple releases macOS 12.5.1, iOS 15.6.1, patches for two zero-day vulerabilities
Both statements can be true, it’s a hallmark of nation states and humble anonymous researchers.
tbrock··on How to integrate a trackpoint in a mechanical keyboard
Why aren’t there more external keyboards made with a trackpoint? Yes I know about the Lenovo ones, they are not great.
tbrock··on Weedkiller ingredient tied to cancer found in 80% of US urine samples
The FDA does not regulate the use of the term “organic” on food labels.

Further, if something isn’t 100% organic how do you know which part isn’t?

tbrock··on Weedkiller ingredient tied to cancer found in 80% of US urine samples
There’s no question it would be better if it were true but how sure can we be that it’s not just the same food with different labels?
tbrock··on Ask HN: What's your experience with working M1 and M2 Macs?
They are incredible. M1 Air is the best computer I’ve ever owned (16gb) and my M1 14 (64gb) is the second best.

I can only imagine that the m2 air with 24gb will be even better. To me the extra weight of the 14 wasn’t worth the extra monitor hookup. The tiny power adapter and no fan airs are where it’s at.

tbrock··on Why Can't Database Tables Index Themselves? (2006)
DBMS don't do this by default because indexes aren't free. Each additional index means the database has to write to an additional location for (potentially) every insert/update.

The feature would need to also keep track of which indexes are unused and remove them over time to avoid the massive write amplification that would come from building a new index for every query that crossed the threshold over time.
