Achieving Maximum Efficiency with Minimal Resources
Steve Wozniak established Apple’s technical foundation through rigorous hardware optimization. He enabled color output on standard televisions and achieved functionality with eight integrated circuits that required fifty components in competing designs.
Wozniak’s initial breakthrough, the Apple I, reduced entry barriers by replacing the toggle switches and indicator lights of early systems with a keyboard-and-display interface. Given the high cost of memory and microprocessors at the time, he selected the MOS 6502 microprocessor—priced at $25 versus $179 for the Intel 8080 and $300 for the Motorola 6800—and engineered a circuit that interfaced directly with a standard television and keyboard. This integration allowed users to input commands and view results immediately, a capability previously limited to costly minicomputers.
His principal achievement was the Apple II. To deliver color graphics affordably without dedicated video hardware, Wozniak leveraged timing characteristics of the NTSC standard. By synchronizing digital signals precisely, he induced the television to render high-resolution color using a minimal set of commercial logic components.

Examination of the Apple II motherboard illustrates Wozniak’s minimalist approach. Earlier systems required dedicated circuitry to refresh dynamic RAM (DRAM) continuously. Wozniak observed that the video subsystem already accessed memory at 60 Hz to render the display. By interleaving memory access, he enabled the video circuitry to perform dual functions—refreshing RAM while generating the video signal—thereby eliminating dozens of components, reducing costs, and lowering power consumption.
Wozniak applied his philosophy of transferring hardware complexity to software during the development of the Disk II floppy drive controller. Conventional controllers of the period typically required more than 50 integrated circuits to synchronize data read and write operations on a rotating magnetic disk. By discarding standard hardware architectures in favor of a software-based state machine for timing control,
Wozniak reduced the design to eight chips. This innovation decreased the cost of floppy storage by an order of magnitude and solidified his reputation as a leader in circuit minimization.

Falcon (1987) was simply brilliant! So good that even F-16 fighter pilots endorsed it for its realism.
It came with a whopping 180 page manual! Ahh, the days when you needed a PhD in physics to play games!
Any old school pilots still around who played this classic?

Reported in May, patched in November.
Google: “Told you we could move quickly!”
‼️ Google won't fix an Android bug that lets one invisible text crash a phone's calling service, researcher Mark Blaszczyk says.
So he just released the Proof-of-Concept!
The malformed message never reaches the inbox and needs no user interaction. It drops active calls, emergency calls included.
He says about 30 sent in a row corrupt the phone's SMS database, so a Pixel 9 or Samsung Galaxy crashes on every boot. A factory reset only helps until the carrier delivers the texts again.
He reported it to Google on 5 May. Google closed it as "Won't Fix" and a "Non-Security Issue".
Readers added context they thought people might want to know
Google will fix it as part of the November security update. A fix has already been pushed to AOSP in October, with the first commit in June.

As someone who has personally spent $500k / mo+ on Google Ads for years, I can tell you with certainty:
This revenue growth in Search is artificial & extremely unhealthy for Google’s business long term
Search volumes are declining as legacy search is being increasingly cannibalized by non-monetized LLM queries
Google’s response?
Manufacture revenue growth via short-sighted, highly extractive, customer-hostile tactics. I.e. charge advertisers more for lower quality clicks, including clicks they do not want and explicitly did not approve Google to charge them for
A few examples to illustrate:
For all of its history until recently, Google operated on a 2nd price auction model
I.e. if you bid $5 CPC and the next highest bidder bids $1 CPC, Google charged you $1.01 for the click (one penny more than the 2nd highest bidder) rather than the $5 you bid
This was a genius move by Google early on as it incentivizes advertisers to input their true maximum willingness to pay rather than trying to play the game of bidding low and constantly adjusting to try to stay just ahead of the next highest bidder while still not paying too much
However recently, Google silently deprecated the 2nd price auction and began charging advertisers as much as their bid and budget caps allow, regardless of what anyone else is bidding
It’s a short-sighted cash grab at the expense of the long term health of the advertiser ecosystem
Making thing worse, Google also recently nerfed keyword targeting precision
Google previously had precise keyword targeting settings that allowed advertisers pick individual search phrases to bid on, defined down to the character w/ exact match or phrase match targeting
This was one of the core features that made search advertising magic, enabling advertisers to run extremely precise campaigns based on exactly what their target customer typed
But now, even if you bid on a specific term or phrase using the strictest exact
-match targeting settings, Google will show your ad across 1000’s of unrelated keywords, labeling them as as “exact match (close variant)”
The definition of “close variant” means whatever they want it to and changes constantly. The result is advertisers get billed for clicks that are totally irrelevant to their business and that their targeting settings explicitly forbid Google from targeting. Google does it anyway and there’s no ability to turn this off
So now exact match is broad match, and broad match is just meaningless spam
This is all very bad for advertisers, but for Google, it allows them to show your ad and bill you for clicks across 1000x more searches that were previously going unmonetized (mainly because they’re garbage queries no one wants)
This is how you grow revenue atop declining search volumes
Lastly, and perhaps most egregiously, Google quietly stopped respecting budget caps by a factor of 2x. For example campaigns we’ve been running for years with $1000 daily budget caps suddenly began spending $2000+ per day
And the extra spend is entirely on the garbage keywords Google arbitrarily throws in as “exact match (close variants)” which have no value to our business, but can’t be turned off
Google offers no refunds nor any recourse for overspend or spend on keywords you explicitly did not target
These are not the actions of a healthy business. These are the actions of company whose core business is in decline but desperately needs to pump quarterly earnings so Wall Street will continue to fund insane capex while hopefully looking through their rapidly deteriorating negative free cash flow
Google operated a benevolent monopoly for the better part of 25 yrs
Meaning the value Google captured from Search was but a small fraction of the value it created, and that spread produced a potential energy that justified expectations of high earnings growth far, far into the future
This is now no longer the case
At the alter of AI capex, Google is sacrificing the golden goose
Q2 was an amazing quarter, with our AI investments redefining what’s possible across every part of our business.
Alphabet revenue grew 24% YoY and Google Cloud accelerated to 82% growth. We saw exciting momentum across the board from Search to YouTube to the Gemini app (which reached 950M monthly active users). Our model APIs are processing 22B tokens/min (up from 16B+ last quarter) driven by our workhorse Flash models. We’re also seeing great adoption of Gemini Enterprise, used by 90% of the Fortune 100, as well as strong demand for our security solutions.
Outstanding results and momentum, and such an exciting moment—thanks to all of our partners and employees around the world! 🙌 About to hop on the call!
This is the key thought experiment about Frontier Models, as they match and exceed human abilities.
Where is the line where the algorithm has rights? Maybe we are not there now, but where is it, can anyone define it?
