rotbart··on CVE Tracker
That assumes AI isn't used to review AI code. As it turns out that AI is great at finding vulnerabilities.
rotbart··on Improper redaction reveals Google Data Center water and electricity usage
Did you stop reading the article at the first data center? "More improper redaction shows that the data center using the most water annually is Fireball Group LLC, the Google Data Center in Papillion. Fireball LLC reports _547.88 megagallons_ for their 2025 Annual Water Consumption." (emphasis mine)
rotbart··on Loss of cell identity drives human aging: Two new papers
The strongest evidence we have of the reversibility of epigenetic aging, as well as its limitations -- are embryos which undergo an epigenetic reset.

After fertilisation, the embryo strips the father's DNA of its age-linked chemical tags and swaps its packaging, destroys his mitochondria, rebuilds telomeres, and clears damaged proteins, though it can't undo the DNA mutations sperm gather as men age.

(those that result in an non viable embryo result in miscarriage.)

rotbart··on Money that sits idle should cost more than money that creates opportunity
Clearly, you have not read the article.
rotbart··on Money that sits idle should cost more than money that creates opportunity
I'm trying to make the case for this model of economy, not claiming it is proven. What in economics is ever truly proven?
rotbart··on How I use Claude Code: Separation of planning and execution
This is a similar workflow to speckit, kiro, gsd, etc.
rotbart··on Giving Claude Code Eyes: Round-Trip Screenshot Testing
I levelled up my Claude Code workflow by giving it the ability to see its own front-end output — automatic screenshots captured during system/e2e tests, wired into a custom Code command that visually inspects every captured frame.

Two files, a few lines of config, and a meaningfully better feedback loop.

rotbart··on Acme Weather
I can't download it, as it appears to be US only. Based on the screenshots, without 'feels like' support throughout the forecast (not just for current conditions) it wouldn't be useful where I live.
rotbart··on The path to ubiquitous AI (17k tokens/sec)
Hurrah, its dumb answer to the now classic "the car wash is 100m away, should I drive or walk?" appeared very quickly.
rotbart··on The architecture of “not bad”: Decoding the Chinese source code of the void
This is not exclusive to the East, but any culture with a high cost of expression. Recent interview with a Russian CEO, talking about how they have "growth across the board, only in the negative direction"
rotbart··on Transparent leadership beats servant leadership
Nothing wrong with the attributes the author groups under 'transparent leadership', but the article shows a certain misunderstanding of servant leadership.

At the core of servant leadership is the idea that leaders shouldn't hoard power, but instead share it and empower their reports. That they are accountable to their reports, rather than the other way.

Nothing to do with acting like a parents and becoming a single point of failure.

rotbart··on Delete tests
So... clickbait title for an article that could have been called "Delete flakey tests"...but then and most of us would have just gone "yep" and not clicked.
rotbart··on Tilt: dev environment as code
Great talk about this... https://www.youtube.com/watch?v=j2AQ9eTZ3-0
rotbart··on Hyrum's Law in Golang
Hyrum's Law especially applies when you have consumers of your APIs that violate Postel's Law. To minimise those in the past, we've introduced intentional jitter in our API responses that while didn't violate the schema prevented unintentional reliance on behaviour that wasn't intentional[1].

rotbart··on Goggles: Democracy dies in darkness, and so does the Web [pdf]
Add: '-site:pinterest.com' to your Google image search to avoid pinterest results.
rotbart··on Apple's plan to “think different” about encryption opens a backdoor to your life
As a former 13year old, that would be the end of 13 year olds using iMessages... I smell an opportunity.
rotbart··on How Going Back to Coding After 10 Years Almost Crushed Me
That's where red-green TDD and pairing comes in. Unit tests != class level tests.
rotbart··on Show HN: I made an alternative platform for professional profiles
Overall would recommend leveraging the schema from JSONResume (https://jsonresume.org/schema/) that supports all of the above
rotbart··on Tiny antibody component highly effective against SARS-CoV-2 in animal studies
More information: Wei Li et al, High potency of a bivalent human VH domain in SARS-CoV-2 animal models, Cell (2020). DOI: 10.1016/j.cell.2020.09.007 http://dx.doi.org/10.1016/j.cell.2020.09.007
rotbart··on Loopy: a tool for thinking in systems
It's a very simplistic tool, but it is great to help visualise and illustrate some systems. It helped me demonstrate the dynamic between technical complexity, delivery pressure and velocity (then add refactoring) https://medium.com/pageup-tech/the-system-of-technical-compl...
rotbart··on Zoom closes account of U.S.-based Chinese activist after Tiananmen event
This just prompted me to cancel my Zoom subscription... I could live with all the security flaws (which were patched quite rapidly) but not with this kind of unethical behaviour.
rotbart··on Postel's Law in Development
Reminds me of how we subverted Postel's Law to uphold Postel's Law https://medium.com/pageup-tech/update-on-driving-client-resi...
rotbart··on Introducing the Keybase filesystem
Shameless request from me as well. Thanks!
rotbart··on word2vec – Tool for computing continuous distributed representations of words
Our technology gives a much better identification of noun senses (http://springsense.com/api/)
rotbart··on List of Machine Learning APIs
Favourite would be NuditySearch?
