juvoly··on I think the military commissary's freezers were hacked
Minesweepers?
juvoly··on An OpenAI model has disproved a central conjecture in discrete geometry
Like the discovery of penicillin by Alexander Fleming in 1928?
juvoly··on CISA Admin Leaked AWS GovCloud Keys on GitHub
When empires collapse, it's usually not caused by a foreign power, but by negligence and corruption from within
juvoly··on Iran demands Big Tech pay fees for undersea Internet cables in Strait of Hormuz
What was the desire? Since the desire was a moving, ever changing, target it seems the force was primarily about showing force. Kind of meaningless.

Indeed, power is about convincing others fear your force. Using force is, in a sense, admitting a lack of power.

juvoly··on I’ve built a virtual museum with nearly every operating system you can think of
Yeah! Browsing through the screenshots truly feels like watching vintage porn.
juvoly··on Iran demands Big Tech pay fees for undersea Internet cables in Strait of Hormuz
The Iran regime was obviously going to be a push over.

Not the first forever war initiated as a Blitzkrieg. Not the last either.

juvoly··on Voice AI Systems Are Vulnerable to Hidden Audio Attacks
> "Audio modality is really challenging to comprehend because of how limited our hearing is"

Would it help to significantly lower the hearing capabilities of the AI system? At Juvoly, we always encouraged GPs to invest in high quality microphone like Jabra Speak, connected through USB. A good mic results in much better audio transcriptions, but maybe that was all for the wrong reasons?

juvoly··on Mercurial, 20 years and counting: how are we still alive and kicking? [video]
You're right about SVN's guts vs Git. I should have been clearer that I was referring to the client cli only.
juvoly··on Mercurial, 20 years and counting: how are we still alive and kicking? [video]
Mercurial wasn't as simple as Subversion. But with hg I still felt like understanding 80% of what the tool had to offer and actually being able to mold the timeline the way I wanted.

Git has so many gotchas, bells and whistles that whenever I'm doing something out of the ordinary I'm wondering if there isn't an easier / canonical / smarter way I should be doing it.

juvoly··on I did everything but my app doesn't attract anyone
The app store looks horrible and barely work. Why would you want to promote your website there?
juvoly··on CUDA Books
Increasingly (for instance ADSP podcast [1]) those in nvidia's inner circle are advocating against writing your own CUDA kernels. (Unless that's your full time job at nvidia, that is).

juvoly··on I don't think AI will make your processes go faster
Indeed, no license burden but you get a maintenance burden instead.
juvoly··on I don't think AI will make your processes go faster
So true.

I can only think of hobby projects, like writing yet another emulator, expression parser or media processor in a new language I'm trying to master.

In a professional setting, you would always diligently explore libraries and only implement your own if there is no suitable alternative.

juvoly··on Clusters become personal (like PCs did)
Does your apple laptop run Linux or MacOS? Do you run Kubernetes locally or only when network permits? What was the reason for targeting Linux rather than MacOS? And what in this context is the value add of using Kubernetes for your development?
juvoly··on Clusters become personal (like PCs did)
Never understood the appeal of Kubernetes to developers, outside of a massive deployments. Always felt like a poor man's Linux for those that insist on using apple or windows desktop.
juvoly··on AI could be the end of the digital wave, not the next big thing
Experience isn't the problem. I have 20+ years of C++ development, built commercial software in Java, Rust, Python, played with assembly, Erlang, Prolog, Basic.

Played with these coding agents for the last couple weeks and instantly noticed the brainrot when I was staring at an empty vim screen trying to type a skeleton helloworld in C.

Luckily the right idioms came back after couple of hours, but the experience gave me a big scare.

juvoly··on Don't rent the cloud, own instead
> Cloud companies generally make onboarding very easy, and offboarding very difficult. If you are not vigilant you will sleepwalk into a situation of high cloud costs and no way out. If you want to control your own destiny, you must run your own compute.

Cost and lock-in are obvious factors, but "sovereignty" has also become a key factor in the sales cycle, at least in Europe.

Handing health data, Juvoly is happy to run AI work loads on premise.

juvoly··on The Cost of a Closure in C
That sounds cool, but this quickly gets complicated. Some aspects that need to be addressed:

- where does the automatically defined struct live? Data segment might work for static, but doesn't allow dynamic use. Stack will be garbage if closure outlives function context (ie. callback, future). Heap might work, but how do you prevent leaks without C++/Rust RAII?

- while a function pointer may be copied or moved, the state area probably cannot. It may contain pointers to stack object or point into itself (think Rust's pinning)

- you already mention recursion, compilation

- ...

juvoly··on Search tool that only returns content created before ChatGPT's public release
Interesting. I guess that analogously, we might find that X years after some future AI content production ban, we could similarly start ignoring the low background token issue?
juvoly··on France threatens GrapheneOS with arrests / server seizure for refusing backdoors
... And what if a competing mobile OS (say iOS or android) received payments or donations from said organization :-)
juvoly··on Contributing to open-source should be required, like jury duty
I think the point is not about us being developers or employees, but about us being a civilian.
juvoly··on ICC ditches Microsoft 365 for openDesk
But would you be willing to pay for it? Would your company/organization be willing to move?
juvoly··on How I bypassed Amazon's Kindle web DRM
Indeed. If DRM had the technical merits to protect against copying, why would we need a (law like DMCA) against tinkering with that technology?
