metaphor··on The Lucretius Problem: How History Blinds Us
This strikes me as a false dilemma.

What's troubling at face value is that the setup nudges us towards the all too common deceit of "past observations beget future outcomes" without saying anything meaningful about forward-looking risk likelihood and consequence.

The architect may think it best to assume the risk; the engineer, control it; the city planner, avoid it; the business executive, transfer it. Perhaps the risk itself lacks specificity. Perhaps mitigation incorporates a bit from all major stakeholders.

Surely there are other options to consider that have yet to be dealt.

metaphor··on Panel with photovoltaic material layered on silicon hits 33% efficiencies
No idea what gives an arbitrary vegetable "flavor" relative to another in the same genus. Given how much of the industry is trial-and-error breeding to objectively target certain characteristics, it's unclear that practicing experts do either.
metaphor··on Panel with photovoltaic material layered on silicon hits 33% efficiencies
Corn tissue...with a very instructive caveat emptor:

> Be aware that elemental concentrations in plant tissue can vary widely for a given crop depending on the stage of growth and environmental conditions and for different crops, yet plants can still appear normal and healthy. For some elements the range of sufficiency is wide and for others the range is narrow. A good deal of caution needs to be exercised in diagnosing mineral deficiencies based only on plant tissue analysis.

Appreciate the cite though.

metaphor··on A table that looks good on mobile and desktop
No thanks. If I need to review a table on mobile, I still much prefer just rotating to landscape, which mobile handles quite well. This very opinionated implementation forces me to switch to desktop mode and rotate to landscape when reaching for pragmatic utility. Surely there's a reasonable usecase, but I really can't think of any tabular data that I regularly review where "tranpose-serialize" would result in a net positive UX.
metaphor··on More than 75% of Steam games tested are playable or verified on the Steam Deck
I suspect the metrics are actually better than reported.

For example, Skul: The Hero Slayer[1][2] is a relatively popular indie game whose Steam Deck compatibility is officially "Unsupported" because "graphics settings cannot be configured to run well", but if you ignored the warning and installed it anyways, you'd be scratching your head in confusion trying to find anything broken compared to PC. Imagining NEOWIZ/SouthPAW Games is liable to have lost quite a bit of revenue because of this seemingly incorrect compatibility listing alone.

metaphor··on Sending audio to LKV373 HDMI extenders (2021)
Yes, the parent's objective clarification below was acknowledged. To be fair, the parent's point wasn't to assert a minimum Ethernet bandwidth that it "could be done in", but merely to highlight the incongruence of the grandparent assuming no compression when transmitting a base case payload over 1 Gbps Ethernet PHY.

I agree that the bandwidth overhead of 8b10b can be dismissed in context, but nevertheless disagree that the underlying functional equivalent of HDMI blanking can be entirely ignored given that's where the audio stream is embedded, with a max +/- 2 ms delay relative to video requirement.

To your point, it's unclear in my mind that even a hypothetical 3 Gbps Ethernet PHY would be sufficient in practice to transmit raw 1080p60 + stereo audio without some form of compression given framing and IP stack overhead, which certainly isn't free; i.e. you'd be at 92.7% link saturation in a completely lossless environment just blindly transmitting raw 1080p60 video data without framing or audio or IP encapsulation.

metaphor··on Sending audio to LKV373 HDMI extenders (2021)
Irrelevant. The hardware under scrutiny is a chinesium HDMI over IP extender with 1 Gbps Ethernet PHY at best.
metaphor··on Sending audio to LKV373 HDMI extenders (2021)
Much closer to 5 Gbps when you factor in horizontal/vertical blanking + TMDS 8b10b encoding.
metaphor··on The unsolved mystery of the Brinks jewelry heist
Touche.

Alas, an inherent risk to the UX surrounding adoption of new technology is we tend to become so engrossed with realizing (P_success * Benefit) that we often dismiss the inevitable consequences of (P_failure * Cost).

metaphor··on Samsung Foundry Tracking 2nm In 2025
The story underlying "best selling series" is buried in details that your 1-liner quip conveniently ignores.

To close FY23, Nvidia reported[1] -27% YoY gaming segment revenue decline, while data center segment saw +41% YoY revenue growth to overtake gaming segment revenue contributions by 65%. -8% YoY gross margin contraction was largely attributed to $2.17 billion Ampere inventory glut in excess of demand expectations.

Take a wild guess which segment accounts for the lion's share of this Ampere inventory glut.

metaphor··on US vendor accused of violating GDPR by reputation-scoring EU citizens
> When BICS acquired TeleSign in 2017, it began to fall under the partial control of BICS' parent company, Belgian telecom giant Proximus. Proximus held a partial stake in BICS, which Proximus spun off from its own operations in 1997.

> In 2021, Proximus bought out BICS' other shareholders, making it the sole owner of both the telecom interchange and TeleSign.

Curious how the article's headline goes out of its way to emphasize "US vendor" when the puppet masters in the underlying corporate structure are entirely Belgian.

metaphor··on Ford CEO: Tesla's Cybertruck Is Only for 'Silicon Valley People'
It sounds like the UK hasn't had its Chicken Tax[1] moment in history yet.

A Chevy Suburban seats up to 9 and has a curb weight of ~6,000 lbs on the upper end.

A Tesla Model 3 seats up to 5 and has a curb weight of ~3,800 lbs on the lower end.

Take a wild guess which vehicle your proposition taxes favorably...something about unintended market consequences comes to mind.

That's a hard sell when the curb weight of a Tesla Model Y is identical to a Ford F-150 5.0L V8 SuperCab with 6.5-ft bed.
metaphor··on ASU: The New American University (2021)
UIUC published stats for 2022[1]: 1 in 4 for engineering and business (roughly top-50 university odds), 1 in 15 for computer science (roughly top-10 university odds), a coin flip or better for most other majors. General admit seems pretty relaxed at 44.8%.

metaphor··on ASU: The New American University (2021)
> It's a matter of pride and honor for me.

That's certainly on you, and to each his own (a freedom we once swore to defend, right?), but this 10-year, 2-tour vet wouldn't dare deny the privilege to the lowest ranking prior junior enlisted desk jockey who served a single term and never once deployed, or even some civilian poser who has yet to internalize the core value of integrity.

The mission requires service of all forms; surely the preservation of pride and honor isn't predicated on taking a bullet or losing a limb or surrendering 20+ years of adult life for country.

> The 10% off everything in store? Yea I'll use that one though but I sure as hell feel weird doing it!

Why? Lowe's rakes in a handsome 33% gross margins and billions in net profit every year[1]. In exchange for extending a mere 10% retail discount to 6.7% minority class, the company receives the intangible benefit of community association, positive PR, and share of a growing homeowner customer base (thanks in large part to the VA) with recurring needs...in other words, it's a calculated business decision and marketing expense, not charity.

metaphor··on ASU: The New American University (2021)
> But if you don’t have a Purple Heart or you aren’t really old you better not park in those “veterans parking” spots I see at Lowes.

The signs at Lowe's say "Veteran Parking Only", not "Purple Heart Recipient Parking Only" or "Retired Service Member Parking Only".

The class of total US veterans represents 6.7% of all US adults 18 years and over on a trend that's been consistently declining for at least the past 2 decades[1]. There's no moral hazard here and Lowe's is kind enough to extend enough privileged parking to go around.

metaphor··on Power companies fight Maine’s proposed non-profit utility
CMP's latest FY22 annual[1; starting p. 130] and 23Q1 quarterly[2] financial statements for the habitual numbers sleuthers.

In case anyone else was wondering what the provenance of this $325MM goodwill line item on CMP's balance sheet is, defer to the parent's (Avangrid) latest 10-K filing[3], buried under footnote 7 on p. 123:

> Goodwill for the Maine reporting unit is $325 million from the purchase of CMP by Energy East Corporation in 2000.

metaphor··on A single line of code made a 24-core server slower than a laptop (2021)
Patterson/Hennessy on Computer Organization and Hennessy/Patterson on Computer Architecture are considered foundational canon.

The implied expectation underlying "beginner-friendly" seems naively misguided; it's an advanced undergrad computer/software engineering topic in the most permissive sense, and the blog's prose appears to have been tailored with that minimum target audience in mind.

Thanks for the clarification; the devil certainly was in the details on that one.

Market price: $75+ a bottle[1]...of course.

I'm somehow reminded of corporate McDonald's grift of contractually forcing Taylor ice cream machines on franchisees.

EDIT: cbfrench below correctly points out that that price is per case...the devil was hiding in the details and I stand corrected.

metaphor··on Lisa Su saved AMD – Now she wants Nvidia's AI crown
Look long and hard at AMD's financials circa 2015[1]...for the sake of anticipated TL;DR, here are a few summary highlights:

  - -27.5% YoY revenue decline
  - -6.3% YoY gross margin decline
  - -$481M operating loss
  - $230M short-term debt
  - $388M non-cancelable operating lease commitments
  - $538M unconditional purchase commitments
  - $2.032B long-term debt (!)
  - -$412M stockholders' deficit (!!)
Seriously, look long and hard at those numbers, and when you think you understand what they might mean, consider them again and again until the feeling of insurmountable adversity sinks in and you're on your knees begging public equity markets for an ounce of capital and a pinch of courtesy faith...on the promise of meaningful risk-adjusted ROIC to be delivered in just a few years.

> But Nvidia gpu datacenter growth isn't new. And AMd were asleep

...which is why this remark comes off as sheer arrogance (no disrespect).

Su and the rest of AMD leadership certainly weren't asleep. The difference here is while you're busy scouting speculative waters defended by competition with deep battle pockets and an even deeper technical moat, Su was simply preoccupied bringing a zombie company back to life and building up enough health to slay a weaker giant.

Personally, I was already beyond impressed with one miracle delivered.

metaphor··on Lisa Su saved AMD – Now she wants Nvidia's AI crown
> Nah. AMD was already profitable in 2018. This is just big mismanagement.

Hindsight bias much?

How easily we forget in today's speculative AI bubble that AMD rolled into 2018[1] with 6.1x levered D/E and substantial business uncertainty while the Fed was actively ratcheting interest rates up, and ended the fiscal year still 3.3x levered despite turning operationally profitable[2].

> Had they done it well, just from the current AI hype the stock would probably be worth 50 bucks more.

It strikes me as pretty audacious and quite unconscionable to assert "big mismanagement" while simultaneously crying about speculative short-term profit taking opportunities.
