jdsully··on Tesla Doors Can Trap People Desperate to Escape
At least for the model 3 the front the door releases are more prominent than the actual buttons your supposed to use - newbies often use that the first time they exit.

But the back doors are a different story. For a few years into owning the car I didn't think they had an emergency release at all. Now I know they are hidden in the door molding somewhere but I doubt I'd be able to find them in an emergency let alone a guest that's in the back seat. It does worry me when I have people back there.

jdsully··on AMD claims Arm ISA doesn't offer efficiency advantage over x86
I don't really understand why the OS can't just trap the invalid instruction exception and migrate it to the P-core. E.g. AVX-512 and similar. For very old and rare instructions they can emulate them. We used to do that with FPU instructions on non-FPU enabled CPUs way back in the 80s and 90s.
jdsully··on Ask HN: Have any successful startups been made by 'vibe coding'?
I built this spreadsheet over a week with AI writing nearly all the code. It doesn't fully fit your thesis because I have experience coding and I did it for fun not as a startup. Now it's not perfect but does have recalc, undo, and file saving working. I think of it more like one of those assisted e-bikes, you still have to pedal but it gets you much farther on each stroke.

jdsully··on AWS pricing for Kiro dev tool dubbed 'a wallet-wrecking tragedy'
The worst thing is they deny access to Bedrock by default. I had to wait two weeks to get access because there support took multiple days to respond. More than enough time for me to port my entire app to GCP out of frustration. GCP has sensible default quotas so you can at least try it without a two week wait. Plus access to Gemini.
jdsully··on I watched Gemini CLI hallucinate and delete my files
The gemini web UI is also the most buggy thing I've ever used and its relatively simple. Its always losing track of chats, the document editor doesn't work properly if you try to make your own edits. Just a general nightmare to put up with.
jdsully··on US 'click to cancel' rule blocked by appeals court
They get to create rules despite being unelected. The catch is they have to follow the procedure for rule making in the law that grants them this power. Even if the rule is a very good idea.
jdsully··on ChatGPT's enterprise success against Copilot fuels OpenAI/Microsoft rivalry
“awareness in the consumer space doesn’t necessarily translate into fit for use in the commercial space.”

Man they sound like a mainframe manufacturer at the dawn of the PC era.

jdsully··on ChatGPT's enterprise success against Copilot fuels OpenAI/Microsoft rivalry
I'm reminded of when .NET was released suddenly everything was .NET, even an office release was named after it. Then it finally narrowed down into the programming languages we know and love or hate depending on your vibe. I assume this will happen here too eventually.
jdsully··on Ancient X11 scaling technology
Windows tried this for a long time and literally no app was able to make it work properly. I spent years of my life making Excel have a sane rendering model that worked on device independent pixels and all that, but its just really hard for people not to think in raw pixels.
jdsully··on Show HN: A DOS-like hobby OS written in Rust and x86 assembly
Nobody cares about Lotus 1-2-3 support any longer :)
jdsully··on TI to invest $60B to manufacture foundational semiconductors in the U.S.
They make really good VCO+PLL chips. Ultra low phase noise.
jdsully··on Rohde and Schwarz AMIQ Modulation Generator Teardown
A 14-bit dac at 105msamples/s with delta sigma modulation means you can get an effective bit depth of ~50 bits @20khz which is a ridiculous amount of dynamic range. Far more than what is implied by "just" 14-bits.
jdsully··on Jemalloc Postmortem
The "greedy" part is likely not releasing pages back to the OS in a timely manner.
jdsully··on MLB says Yankees’ new “torpedo bats” are legal and likely coming
They actually try to just block without the stick until the play ends and it looks rather silly. I've also seen them dive and punch the puck which doesn't seem like it should be legal but the rules seem to be limited to prohibiting grabbing the puck.
jdsully··on 'Naive' science fan faces jail for plutonium import
That's basically the entire premise behind a jury trial.
jdsully··on Raspberry Pi RP2350 Now Available for Purchase, Stacked Memory Variant Coming
$1m is peanuts if your making chips. They should have done a respin for such a fundamental issue. This errata will be one of the first things you see when you research the part even if they later fix it. You can see even here it's half the discussion so far.
jdsully··on Raspberry Pi RP2350 Now Available for Purchase, Stacked Memory Variant Coming
Its known not to have a very good ADC. They did a good job on a lot of the digital aspects but the analogue leaves a lot to be desired.
jdsully··on Why data on the economy doesn't match our feelings
Thats basically 99% of political discourse at this point. Not a lot of laughing these days.
jdsully··on Microsoft Windows 1.0 with Steve Ballmer (1986)
In the BillG era it was pretty common to produce these funny videos for internal events. In case anyone is wondering about the origin of this.
jdsully··on Apple says it will add 20k jobs, spend $500B, produce AI servers in US
Careful when comparing performance and efficiency. As a rough factor power increases quadratically as you increase clocks on a design, so you can quite easily make a high performance design low power by under-clocking it. The same is not true for the reverse.
jdsully··on Gold Is Worth More in New York
The role of the exchange is to facilitate orderly markets by reducing counterparty risk. My knowledge is more stock market than commodities but normally they require collateral from the brokers so that they can recover from the broker, but ultimately they would be on the hook if they failed at their risk management. In reality though we know the government would not let a major exchange fail so there's also that unwritten rule.
jdsully··on Disabling Zen 5's Op Cache and Exploring Its Clustered Decoder
Yea have a small security processor. I think it makes a lot of sense.
jdsully··on Warren Buffett is no longer donating his money at death to the Gates Foundation
The article author seems a bit salty at this turn of events.
jdsully··on T-Mobile users can try Starlink-enabled phone service for free during beta
Its much more scalable to enforce your own boundaries rather than rely on the defaults provided by technical limitations.
jdsully··on Cybertruck's Many Recalls Make It Worse Than 91 Percent of All 2024 Vehicles
Seats are extremely uncomfortable for people of certain heights. The main issue seems to be the headrests aren't adjustable without tools.
jdsully··on Mark Zuckerberg Wants to Feed You More AI Slop
low single digit thousands.

Graham has a great but very dated article on it: https://paulgraham.com/submarine.html

Its only gotten worse as news orgs' finances have declined. At least this one is in the opinion section.

jdsully··on Mark Zuckerberg Wants to Feed You More AI Slop
Its better for whoever paid for this advertorial to be published. I think people would be shocked how cheap it is to get articles placed these days.
jdsully··on Ford seeks patent for tech that listens to driver conversations to serve ads
But that's the point, you need consent of the person on the other side of the line too which didn't sign the EULA
jdsully··on iPhone 16 Pro and iPhone 16 Pro Max
They have classes full of "normies" trying them out every time I pass by my local store. Sure looks like its meant to be something other than a dev kit to me.
jdsully··on Reverse-engineering my speakers' API to get reasonable volume control
With youtube premium you get no ads on youtube and youtube music. Its a great deal.
