BobbyTables2··on What Do We Know About the Microplastics Inside Us?
So microplastics are indeed harmless!

(/s)

Too bad common discourse is too distracted to consider nanoplastics…

By the time the public tires of microplastics debates, they’ll be in no mood to relitigate nanoplastics

BobbyTables2··on A software engineering interview question I like: computing the median
Or do a bucket sort on 32bit integers for worst case O(n) time, not O(n^2)

Only half kidding…

Using just 16GB RAM for a task is practically resource-constrained programming these days…

BobbyTables2··on Patching MechCommander's "left arm bug" for fun and profit
How can you be dead certain that all references are known in Ghidra?

Just non-disassembled function or unidentified struct would ruin your plans…

BobbyTables2··on The difference between "today's task" and "accretive work"
Nor the CI test that fails each day
BobbyTables2··on Almost Always Unsigned
Considering Rust doesn’t have such nonsense, I’m inclined C/C++ have utterly broken generations of programmers.

In what world is using a signed value to index a normal array a good idea?

Makes for horrible footguns like:

history[counter % SIZE] = …

(One cursed day counter rolls over, becomes negative, and an out-of-bounds write occurs)

Everything went South as soon as we broke the abstraction of arrays and treated them as pointers.

Commenters here are pretty much arguing which way to hold scissors while running instead of realizing that one shouldn’t do that in the first place…

BobbyTables2··on Men's average testosterone levels have halved in last 50 years
I really wonder, what is “normal”?

One class of doctors thinks roughly 250 is enough for a middle aged guy - anything over shouldn’t be medically treated. Of course, the “men’s clinics” don’t rest until it’s over 1000...

With the standard range so wide (even after age adjustment), why isn’t it measured annually, like the CBC and others?

Sure, it’s easy to point at obesity, but statistical ranges completely fail the individual.

BobbyTables2··on Why skilled workers come to Germany and then leave again
What other country looks appealing?

I get the whole “speak the native language” but seems like the appealing countries speak a language most of the world doesn’t care about.

The number of countries with English as the main/official language that are desirable and open to immigrants seems really small.

BobbyTables2··on A global workspace in language models
Just today Google’s AI told me that 3**4 was 181 because I asked it for bases such that when raised to the 4th power had a 1’s digit in the leftmost place.

Yeah, LLMs aren’t designed for this kind of thing but it was really confident in its assertion… it picked the example too!

BobbyTables2··on The AI Compass Quiz
I’m convinced there is a sizable chunk of the population such that if they knew an AI was conscious, then they would mistreat it as fully as possible.
BobbyTables2··on Fines doubled as teens outsmart Australia's world-first social media ban
Considering elementary school kids have no trouble bypassing school firewalls, I’d be genuinely disappointed if teens couldn’t do better…
BobbyTables2··on Rayfish, Peer-to-peer mesh VPN with no server to trust
A webserver could alter the payload based on the client.

An evil person could present a normal install script for other browsers and randomly present a malicious one for curl clients.

At least with the downloaded file, that is the thing you get.

BobbyTables2··on Completing a computer science degree on Coursera
Even for research, a lot of CS papers seem like cosplay.

In the place of hard math, models, proofs, quantitative analysis of past approaches, etc. there is simply an “Architecture” section with much navel gazing. The paper topic is not a formal analysis but merely a description of a thing that was made.

Ironically, the least important part of an engineering research paper is the part describing the thing actually built/simulated. That is merely validation of the theory.

BobbyTables2··on Does code cleanliness affect coding agents? A controlled minimal-pair study
Feel the same way myself when working in messy codebases… At some point, the horrible patterns start to rub off…
BobbyTables2··on Pi squared is nearly 10
They’ll also wonder why humanity has so many references to a video of a young orange haired guy singing a song.

Only reasonable conclusion is that he is worshiped as a deity …

After all, He is never gonna give up…

BobbyTables2··on Instead of banning AI, I made a classroom contract with my students
If there were a way an AI could generate output only based on the student’s own knowledge, it could be somewhat beneficial...

Unfortunately that’s not how it works…

Long ago, WordPerfect’s grammar checker showed me my writing flaws and helped me improve.

Pasting a poorly written report and getting a dramatically restructured report wouldn’t be as instructive, even if the final result looked “better”.

BobbyTables2··on Program-as-Weights: A Programming Paradigm for Fuzzy Functions
Despite the appeal of such an approach, I find this extremely unsettling.

Imagine if we had declared that Math for FIR filter design in Signal Processing was too difficult, so we’d just test random FIR coefficients until something good came out.

That sounds pretty horrible but at least the frequency response of the resulting filter would be known. We’d at least understand the behavior of the final product.

With LLMs, we don’t even know what we’re getting out of it.

(And no, I don’t see anything wrong with adaptive filters and such. Their behavior can still be quantified)

BobbyTables2··on Why Switzerland has 25 gbit internet and America doesn't
I have to wonder… is there enough content hosted locally in Europe that having >1Gbps Internet is of actual use?

Sure would suck to have 25Gbps internet if mainly used to fetch files from the other side of the pond…

BobbyTables2··on An American Privacy Emergency
Always wondered about this…

Are politicians really so beholden to an anonymous donor that makes a single $50k donation? Or even a single $500k one?

Or is it the real knowledge that said known regular donors will continue indefinitely as long as things go their way (and indefinitely support the opposition otherwise) …?

The pessimistic part of me wonders if a grassroots campaign that raised $10M would even be able drive any change with it.

BobbyTables2··on Weave Robotics launches Isaac 1, a $7,999 home robot with Fall 2026 deliveries
They’re also much less likely to film their activities and upload it to the Internet…
BobbyTables2··on I built a 10 inch mini rack from aluminium extrusions
Nice writeup!

Always thought extrusions were expensive. At least had found a company custom cutting them but the price was something like 20x what you got.

BobbyTables2··on Alan Kay on the meaning of "object-oriented programming" (2003)
Generally speaking, toy examples can always be made to look simple. In reality it often means the “hard part” was moved into the shadows, not actually solved.

Graphical programming like LabVIEW looks very appealing. The product demo practically sells itself. Sure, it fits well for a very narrow class of use cases. But even fairly simple things in a textual language quickly become an unwieldy mess. (Try factoring an integer in it…)

There are formal models for distributed systems often solve the “easy” problems that didn’t need solving while making various practical concerns harder/impossible such as timeouts or node failure.

BobbyTables2··on Scientists find molecular-level evidence for two structures in liquid water
Agree! Someone once told me that homeopathic doctors often put significant amounts of allopathic medicine in their “homeopathic” concoctions. Does wonders for effectiveness! Perpetuating the classical myth in this manner is also great for business!

Of course, there are also a number of cases where western “supplements” were caught containing actual prescription medicine, not just natural precursors or such. Same idea…

BobbyTables2··on A native graphical shell for SSH
Reminds me of “WebRSH” back in the day.

There was also a standalone Java based SSH client that worked from browsers. (Of course now with WebSockets and modern JavaScript capabilities, no need to have the a “real” SSH client on the user’s actual system…)

Unfortunately, not sure there is enough drive for mainstream applications to be developed in for this proposed “web native” interface. Practically speaking, there would probably have to be a way to run them as native GUI apps without the browser or for a text terminal.

Unfortunately, the three environments have relatively little in common aside from the trivial parts… Operating efficiently in all quickly becomes nontrivial…

BobbyTables2··on Some Simple Economics of AGI
Articles like this feel overly optimistic.

It would be ludicrous to assert that YouTube video viewing compresses the learning time, allowing one to become an Olympic coach in a sport without ever having played it.

Yet, it the article claims that humans can merely define intent and supervise the AI’s output - the same humans that used the AI to avoid the tedium and time commitment required to obtain mastery from actual work.

Perhaps I’m sorely mistaken. All those coworkers who went up the management chain after 2-3 years experience are the foremost technical experts in their field. They merely press a single button like George Jetson and the AI will figure out all the details!

BobbyTables2··on Anatomy of a Failed (Nation-State?) Attack
True, but the past 6-7 years make me seriously question whether it’s real growth or inflation.

For >10 years prior I had a fairly flat salary at two separate employers. Yearly raise of about 2%.

Now salary is up about 50% from almost 10 years ago and home value almost doubled during the same timeframe.

I know I’m not that lucky in life… I don’t live in a HCOL area. I don’t work in an industry that is on fire. Nobody actually gets huge raises for performance.

Sure, the stock market has seen enormous gains over the past 10-15 years. Even the major indices have maintained gains that would traditionally be unimaginable.

That can’t be real growth - it’s the recipe for inflation.

If half the country owned $1000 of NVIDIA 20 years ago, would we be richer? No, inflation would follow and the other half would be poorer…

BobbyTables2··on Turn your site into a place people can bump into each other
So make it a public C&C server???
BobbyTables2··on Enhancing x11 Application Security with LXC (2025)
Yeah, sadly Firefox and Chrome want almost full privileges so that they can sandbox themselves.

X itself always bothers me. Xeyes is cute until one considers the practical implications…

BobbyTables2··on How Many Elementary Particles Are There, Really?
Not being a Physicist, I have to wonder if all these particles are somehow manifestations of a simpler thing.

Might there have been a point in time (long ago) where the “wave photon” and the “particle photon” seemed like possibly different things?

BobbyTables2··on Beer CSS – Build material design in record time
With the first project advertised being a Rust implementation of Remote Desktop, I’m really confused what’s going on here.

The whole website feels like a weird hallucination…

BobbyTables2··on How H-E-B became Texas' most beloved brand (2024)
Sigh… They’ll never be able to compete with Kroger’s wide selection of extremely expired food.
