vitorsr··on iPhone Pocket
Reminds me of waterproof phone pouches.
vitorsr··on Vodafone Germany is changing the open internet, one peering connection at a time
Telefonica does this.

Until I switched, it would only peer with other Tier 1 providers 2000 mi away from my location, even though there is a large IX 5 mi from home co-located with a large regional ISP with several other networks and appliances connected to it.

I filed a complaint but it is impossible to escape the event horizon of the customer service black hole, and customer protection regulation agents fail to appreciate how clownish it is to have 100 ms ping to my university 5 mi away.

So I switched and recommended everyone within earshot to do so as well.

To this day I fail to understand the logic behind not peering locally.

vitorsr··on Typst's Math Mode Problem
> Typst has made some basic choices, which as someone who typsets a lot of math, makes it a no go.

For me, breaking from not just a 40-year-old history of mathematical typesetting but also from the American Mathematical Society recommendations is the dagger. Plus doubling work if you want to reuse what you wrote to render MathJax or KaTeX.

> $\alpha x$ is correct and $\alpha\beta$ is correct, but $\alphax$ is not.

Like you said, braces can be used so all of the following are valid: ${\alpha}x$, $\alpha{x}$ or the odd $\alpha{}x$.

vitorsr··on AI coding agents are removing programming language barriers
I taught Digital Design this semester - all models output nonsensical VHDL. The only exception is reciting “canonical” components available on technical and scientific literature (e.g., [1]).

vitorsr··on A year of funded FreeBSD development
This comment does not present the full picture.

First, it presents the snapshot of donations within a given year to the Foundation. The history of donations is not represented by definition.

Second, it does not present contributed development. Those are typically summarily available on the release notes of each release [1].

vitorsr··on Compiler Explorer and the promise of URLs that last forever
> you can configure it to automatically archive every page you visit

What?? I am a heavy user of the Internet Archive services, not just the Wayback Machine, including official and "unofficial" clients and endpoints, and I had absolutely no idea the extension could do this.

To bulk archive I would manually do it via the web interface or batch automate it. The limitations of manually doing it one by one are obvious, and the limitations of doing it in batches requires, well, keeping batches (lists).

vitorsr··on Garmin's –$40B Pivot
> Garmin's unwavering commitment to physical buttons and how you can customize what they do is what makes them the gold standard in this area for me.

Most people may be unaware that Garmin has a strong foothold in the stringently regulated avionics industry, in particular in flight instruments, displays, deck and others human-machine interface products. In turn, specific regulations informed by ergonomics research are unambiguous in prioritizing safety and unanimously contain minimum usability requirements.

As an example, an AC [1, Ch. 7] advises on (electronic display) control devices, and another AC [2] advises on design and evaluation of controls and displays. The software-defined counterparts have immensely harder requirements that must be satisfied, which, in my reading, is incompatible with pure touchscreen devices.

vitorsr··on Ask HN: SWEs how do you future-proof your career in light of LLMs?
This... for my most important use case (applied numerical algorithms) it is in fact beyond not useful, it is negative value - even for highly available methods’ codes.

Sure, I can ask for it to write (wrong) boilerplate but it is hardly where work ends. It is up to me to spend the time doing careful due diligence at each and every step. I could ask for it to patch each mistake but, again, it relies on a trained, skillful, many times formally educated domain expert on the other end puppeteering the generative copywriter.

For the many cases where computer programming is similar to writing boilerplate, it could indeed be quite useful but I find the long tail of domain expertises will always be outside the reach of data-driven statistical learners.

vitorsr··on Eye Contact Correction: Redirecting the eyes to look at the camera
> I know there is already heavy noise reduction, color correction, auto exposure etc ... but no need to use that to justify more tampering with individual facial features and expressions.

Critically, the enumerated computational processing units are global transformations, while tampering is inherently a local, "contentful" transformation.

vitorsr··on LaTeX Style Guide for EE 364B [pdf] (2014)
You're right, thanks. English is not my mother tongue so I still fall for some language traps.
vitorsr··on LaTeX Style Guide for EE 364B [pdf] (2014)
This is great advice.

I only contend on two things. First is recommending Strunk and White - in general a style guide should not stifle writers' voices and instead equip them with tools to express their own. Here I would rather recommend the far more authoritative and comprehensive The Chicago Manual of Style [1]. Second is excess punctuation - easily incurs in too much line noise. You should generally avoid adding distracting elements seldom added pro forma.

The best source for me has been the Handbook of Writing for the Mathematical Sciences by Nicholas J. Higham [1]. His I can fully get behind. Another is Writing Mathematics Well by Leonard Gillman [3]. Still another is Mathematical Writing by Franco Vivaldi [4].

vitorsr··on Is .NET just miles ahead or am I delusional?
Curious - there is one unnoticed comment on the thread that reminds me of my experience:

> I feel the opposite. Was trying some number crunching, ok net doesnt have an fft.

> What about digital filters... well... lacking

> Displaying scientic graphs, like matplotlib. Nope, there might be a commercial package, but I didnt get a budget.

As someone trying to develop numerical “enterprise” applications in the most boring, maintainable and longevous stack as possible, am I to write and maintain my own foreign function interfaces?

The way large trades are done is you structure periodic block trades representing a small fraction of the volume in that time period. As an example you would sell 10% of the daily volume every day until you finish liquidating your assets.
