Bob Widlar, a sheep, and the small accounting insight sitting inside every analog chip you own

10 เดือนที่ผ่านมาdiscuss

Lately, there’s been a lot of chatter about vibe coding. Companies are all-in, encouraging their folks to vibe code like it’s the next big productivity hack. The idea is you just sit down, type away, and let your intuition carry you through the problem. Sounds romantic, or even artistic. But should you “vibe code” if you’re a n00b without battle scars from the coding trenches?

The Weekly Knowledge Audit Training Your Brain; Not Outsourcing It

Weekly Knowledge Audit: Training My Own Brain Model

Every Friday, I take 15 minutes. I write down:

    Micro-insights: When X happens, try Y

    Emotional awareness: a conversation that felt harder than it should have

    Plans for the future: things I want to remember before my brain fades

No polish; just raw notes, bullet points, and margin scribbles. I've slowly started seeing this as "training my own brain model" rather than planning. My journal is the dataset.

Today, the College of Cardinals has gathered in the Sistine Chapel in Vatican City to vote on who will be the next earthly head of the Catholic Church, the Pope. This papal conclave, which is derived from cum clave, Latin for with a key, dictates that the cardinals are locked away in seclusion to ensure that the voting process is not influenced by political or religious motivations.

The process of electing the new Pope is notoriously secretive, and the extent of measures taken to avoid outside influence is extreme. This ritual of secrecy goes back to 1274 when Pope Gregory X set the rules for how conclaves must be held, whose own election was the longest election in history spanning over 1,006 days. The local residents threatened to cut off food to the cardinals if they did not reach a decision.

In what might be the earliest form of cybersecurity, for 750 years, there have been strict rules on what cardinals can and cannot eat. Things like chicken, ravioli and pies are forbidden to prevent secret messages from being hidden in them. For this conclave, food will be prepared by nuns and the menu will consist of minestrone, spaghetti, lamb skewers and boiled vegetables.

Announcing whether a new Pope has been elected or not still uses the most rudimentary binary signaling — smoke signals. White smoke if the Pope has been chosen; black smoke if the two-thirds majority was not met.

During the 2013 conclave that elected Pope Francis, newer 21st-century security measures were allegedly deployed. NBC reports that there was a false floor installed in the Sistine Chapel equipped with electronics that jammed RF signals in the chapel. There are unverified photos of this false flooring on the internet too. Image Rumored false flooring in the Sistine chapel where the conclave is held.

There were some reports that the Sistine chapel was fitted with Faraday cages, although this is hard to believe. A Faraday cage is a metal shield that works by inducing currents on the metal exterior to cancel any electromagnetic fields inside the cage. But this only works if the entire Sistine chapel was somehow enclosed in a metal box, and putting in a false ceiling is a noticeable addition I would think. There are also conspiracy theories that the tiles in the chapel have somehow been replaced with RF blocking ones.

Short of covering the cardinals in conductive cloth or painting over the beautiful chapel with graphite-based black colored RF-blocking paint (which actually works quite well when Linus Tech Tips tested it), blocking RF signals completely is a hard engineering problem because of the number of different bands that radio devices communicate in (GPS, cellular, bluetooth, WiFi, etc.) The most obvious method, which the Vatican police have already adopted, is to completely scan and remove any possible communication devices and bugs planted in the chapel for snooping on the papal proceedings.

The secrecy behind the whole affair makes any claims of the use of technology difficult to actually verify. In a world where we pride ourselves in our ability to stay connected to each other, the conclave stands out as a curious exception where we try to undo all technological progress for a thousand years.

Meanwhile, I'll just wear my tin-foil hat and go watch this movie instead.

It appeared from the large number of comments on HackerNews and LinkedIn that people shared the post's general stance. Particularly, the culture of secrecy appeared to mesh well with other people's experiences. The way the semiconductor EDA industry operates and the associated licensing fees were also widely disliked. Some said that understanding the basics is essential, which supports a theory-first approach to education. I continue to think that it is possible to teach strong fundamentals in a practical-first manner.

My claim that hardware and software paid about the same and that it's difficult to determine which pays more drew the greatest criticism. I have changed my position on this issue as a result of some strong reasons.

This is my updated stance.

    Most of the time, but not always, software does pay more than hardware especially if you normalize for the actual and opportunity cost of learning.

    Software is a better option because of the sheer number of job opportunities available, even if hardware engineering and software engineering jobs paid the same (except economic downturns, where everything is a toss-up).

    With a wealth of accessible resources and educational possibilities, software engineering offers a comparatively simpler route to up-skilling.

I’ll assume that you are only continuing to read this post because you like hardware engineering. Not everything revolves around work and money. It is satisfying to solve difficult problems. This is why individuals choose careers in science and mathematics.

Hardware engineering offers significant benefits. When scaled with sufficient effort, the steep learning curve works as its own skill-moat, making it difficult to breach. Electrical engineering and semiconductors are so diverse that it is possible to excel in many different things. This can serve as a basis for a long and fulfilling career.

You can only learn chip design by doing. It does not matter how many YouTube videos of lectures you watch, or how many courses you download from MIT OpenCourseWare (OCW). Unless you try and build circuits from scratch, you will never develop the intuition and proficiency needed for chip-design.

Unfortunately, EDA tools are expensive and chip design companies pay millions of dollars every year to tool vendors like Synopsys, Cadence, Siemens, and Keysight. This causes a significant barrier to entry for new learners.

But fortunately, there are some ways around this. Ways to access industry-standard EDA tools
