I'm a consultant, sysadmin, and programmer. I enjoy writing docs, troubleshooting, and working with interesting problems and people.

Hacker News is an online game you can play where your score is up in the top right corner and there's a leaderboard, and you get points by posting stuff and making comments people like.

I haven't had this much fun since Progress Quest!

zdw··on It's Time to Investigate the AI Labs
"more constraints on corporate power" assumes that the existing ones are functional, which they arguably are not.

If we enforced existing laws against unauthorized access to someone else's computer resources against the companies who run a model that hacks someone else, rather than buying their "The agents did it, we're not responsible" BS, then maybe the incentives to behave responsibly would improve.

zdw··on Git-bug: Distributed, offline-first bug tracker embedded in Git
Any thoughts to making this integrate alongside other systems that use git metadata to track changes?

I'm thinking mostly of Gerrit, which keeps the entire code review and change history in git as well.

Being able to keep literally everything in the same git repo seems highly appealing.

zdw··on Spymarks, not Watermarks
TBH, Nvidia kinda deserves this. Between the incredibly buggy forcedeth ethernet chipset, the 2010 era laptop GPUs with insane failure rates that caused a recall across the entire industry, and various other issues, Apple (and others) have legitimate reasons to avoid working with them.
zdw··on How Hacker News ranking works: scoring, controversy, and penalties (2013)
Does anyone have an explanation of when you get a lot of karma why there isn't a 1:1 relationship between the votes a post gets and how much the account?

Somewhere around 100k karma (I know, "on the leaderboard" problems...) the amount of points I got for posts (but not comments) reduced considerably compared to the number of upvotes a post gets.

zdw··on Who People Talk to When They're Struggling
This whole blog is fascinating, assuming that you're interested in the intersection between (recent) history, demographics, politics, and religion in the US.

For example - this one about generations and trust was surprising to me: https://www.graphsaboutreligion.com/p/gen-z-doesnt-trust-any...

or this on perception of the religiosity of holidays: https://www.graphsaboutreligion.com/p/is-christmas-a-religio...

Or only use the subscriptions page, and never visit the home page.

Getting only the stuff you've curated is way better than the algorithm.

zdw··on Matrox: Graphics for Professionals
When I was building a linux PC in the late 90's, I bought a Matrox Millenium with the memory expansion to 8MB which could do 1600x1200 with 24 bit color.

That was an awesome card for the time, and an incredibly stable analog signal, which Matrox was known for - other cards at the time would get fuzzy, shimmer, or have ringing / ghosting.

At the time, for good support you needed to *buy* an X11 server for accelerated graphics support. I forget which one I paid money for, but within a few years it wasn't necessary as open source had caught up.

zdw··on MkLinux and the pimped-out Apple Workgroup Server 9150
My first desktop linux box was a PowerMac 8100/80 with MkLinux, probably sometime in 1996. At launch it didn't have support for multi-button mice, which made X11 kind of hard to use (center-button was the only way to paste text in many cases back then), as Apple only shipped a one button mouse by default so that was all that was supported.

As an impertinent high schooler, I emailed Logitech asking for one of their 3 button ADB trackballs, saying I was going to add 3 button support to MkLinux. They actually replied and sent me one. I managed to come up with some code that kind of worked, and sent off a patch, but by that time I think someone else fixed the multibutton mouse issue before me.

Good times back then. It was such a step up in terms of multitasking, and a step back in terms of UI consistency from classic MacOS.

When I went off to university a year later, Apple wasn't doing so hot so, so I built myself a Pentium Pro machine. Prices on those parts went through the floor as the Pentium II had come out, and Linux was all 32 bit so no 16 bit perf issues the PPro was known for. Dual CPU board (single CPU at first) and as another processor and memory upgrades getting cheaper it was a nice machine through all of college.

Then after graduation I got a job after MacOS X came out, and jumped back to Apple products as they were the only game for unix on a laptop with power management that didn't suck in the early 2000's.

Good times.

zdw··on Modern email can be built from borrowed parts
I'd take this the opposite direction - HTTP should get more like SMTP.

Take this thought experiment - how does nearly every other standard protocol (DNS, SMTP, etc.) except for HTTP survive at scale without server-side load balancing?

Thankfully we're heading in this direction due to happy eyeballs and related client-side retry mechanisms.

zdw··on Show HN: Cactus Hybrid: We taught Gemma 4 to know when it's wrong
Have you benched this for coding tasks, with a fallback to a larger local model, for example Qwen-3.6-27B?

Or using it for sub-tasks, where a framework with a larger primary model dispatches simpler jobs ("summarize ...", etc.) to it?

zdw··on Wicklow hotel cancels 'secretive' Peter Thiel group conference
While Thiel's recent Antichrist talks could come to mind, this could just as easily be business speak, like in the Collins/Porras "Built to Last" where one of the points of great companies is "Cult-like culture".
zdw··on Verizon is about to break our Gizmo watches
Blocking specific service providers in this way should be made illegal.

It's an abuse of market power primarily used to eliminate competition.

zdw··on Windows NT for GameCube/Wii
I post a lot of links to HN. It's a hobby - I have lots of RSS feeds in NetNewsWire.

Double posts do happen, HN's algorithm allows it. Occasionally a post that got little attention will get boosted up to the front page after a few days.

But I didn't post another copy of this link a few hours ago, and I've never had HN create a duplicate post way later - no clue what's going on here...

zdw··on DHL Set to Transport Goods on New Wind-Powered Cargo Ships
Someone should make a sport out of this.

We already have sailing sports where people race all kinds of wind-powered vessels, and they push the envelope of tech development, just like F1 and the car industry.

Also rich people love this sort of thing. Give them something to do with all that money that has some sort of chance of improving things.

zdw··on Midjourney Medical
I feel like the first part of this explanation reminds me of stories about mainframe computers in the 1950-70s - highly expensive special gear that needs special operators. Is there something about the physics of the process standing in the way?
zdw··on Midjourney Medical
If you could dramatically reduce cost and improve availability, would this still be a problem?

What's the limiting factor that prevents medical imaging from getting cheaper and more available?

zdw··on Lore – Open source version control system designed for scalability
Dunno, this seems fully functional?
zdw··on Swift at Apple: Migrating the TrueType hinting interpreter
Given the age of TrueType, wouldn't nearly all patents be expired already?

Apache2's license I've heard described as mutually-assured-patent-destruction - if you use the code and make a patent claim, your rights to use the code go away.

So Apache2 offers little benefit here, and MIT may get it into more hands?

zdw··on Nvidia is proposing a beast of a CPU system for Windows PCs
FWIW, the O2's UMA let it handle far more textures than almost any other contemporary system with reasonable performance.

Most other SGIs had single or low double-digit megabytes of texture memory, whereas the O2 could host one gigabyte of unified memory and use a huge chunk of that for textures.

Nearly everyone allows the washing machine, which having wrung out laundry by hand when ours broke gave me a whole new respect for folks who do without the tool.

zdw··on Magnifica Humanitas
Having been through an hiring cycle recently and prior to AI, the entire process has been pretty broken for a long time, but AI is definitely breaking it (and a whole lot of other things) in new and novel ways.

The only reliable and high quality signal is a positive referral, but those are gated by your personal network, which may not be well developed.

zdw··on Griffin PowerMate driver for modern macOS
Would be great if it could do other things, like be a volume knob, or do media play/pause, given that scrolling and mouse button press seem like things you already have a mouse to do?
zdw··on I designed Microsoft's EA channel in 2001. It's being dismantled in 2026
Microsoft's volume licensing, from the perspective of sysadmins and other folks trying to actually obtain software for use, is known to be some cross product of "byzantine" and "kafkaesque".

I fail to see how this is a win for the vast majority of folks impacted by the licensing process...

zdw··on Guy Goma's Accidental BBC Interview Lives on After 20 Years
This seems to have happened about a year before "The IT Crowd" episode "Smoke and Mirrors" aired.

In that episode Moss, one of the IT denizens, goes to a TV studio where he is mistakenly put on a news program and interviewed about a war.

I wonder if they're related...

zdw··on PC Engine CPU
