The Black Box on the Org Chart

Igor — Mon, 06 Apr 2026 00:17:50 +0000

There’s a particular kind of delusion that takes hold in tech booms. It starts with a true thing, wraps itself around a useful thing, and then inflates into a preposterous thing. The true thing is that large language models can be useful. They can summarize, scaffold, autocomplete, translate from one notation to another, and generate […]

The Post-Language Future of AI Systems

Igor — Thu, 02 Apr 2026 05:28:45 +0000

There’s a persistent assumption baked into how we talk about AI: that language is fundamental. That intelligence expresses itself through something like English, or at least through structured programming languages we recognize. It’s a comforting idea. It’s also probably wrong. Language, as humans use it, is a workaround. It’s a lossy, error-prone encoding layer that […]

Outsmarted by a River, a Rope, and an Anchor

Igor — Thu, 02 Apr 2026 02:50:05 +0000

Before you entrust serious decisions to AI, consider that the most advanced systems routinely fail at school-level physics problems written over a century ago. Here’s why, and what it reveals about how these systems actually “think.” Yakov Perelman never discovered a law of physics. He never led a research program or published in a major […]

The AI Bubble Isn’t a Bubble. It’s a Trap.

Igor — Thu, 26 Mar 2026 05:27:57 +0000

Let’s dispense with the fantasy right away. Your $20-a-month ChatGPT subscription isn’t paying for anything remotely resembling the actual cost of running modern AI. It doesn’t cover the data centers, the power bills, the GPUs stacked like gold bars in climate-controlled bunkers. Not even close. Right now, no major AI company is profitable. None of […]

Validating HTTPS Cache Peers for Squid

Igor — Sat, 13 Dec 2025 10:19:15 +0000

Originally published December 14, 2019 @ 11:52 pmI have a squid proxy server that uses a long list of authenticated cache peers in a round-robin configuration. The process looks something like this: The key to getting this setup working well is to weed out unresponsive cache peers. In my case the proxies used as cache […]

Updating PHP 5.6w to 7.1u on CentOS 6.10

Igor — Fri, 21 Nov 2025 17:50:41 +0000

Originally published November 23, 2019 @ 11:24 amThis is mostly just a note to self. As I mentioned previously (probably more than once), I very much dislike systemd and will stick with CentOS 6 for as long as possible. Having said that, WordPress dashboard has been nagging me about having to update PHP. So here […]

Windows 10 Upgrades

Igor — Fri, 12 Sep 2025 19:35:46 +0000

Originally published September 14, 2019 @ 8:56 amI did the only sensible thing and disabled automatic updates on my two Windows 10 laptops. Microsoft’s belated foray into the world of CI/CD for releasing Windows patches suffers from limited automated testing. As you might’ve noticed, the slew of recent defective patches from Microsoft primarily breaks visual elements […]

LLM Collapse Explained

Igor — Tue, 27 May 2025 16:35:03 +0000

Overview Model collapse in large language models (LLMs) occurs when models repeatedly train on their synthetic outputs, gradually reducing the diversity, accuracy, and alignment of generated content compared to original human-produced data. Detecting and measuring this issue is crucial to maintaining the quality of these models and avoiding cumulative errors across training cycles. Detection methods […]

Notes on ownCloud configuration

Igor — Fri, 21 Mar 2025 19:43:39 +0000

Originally published March 22, 2019 @ 11:22 pmThe ownCloud file sharing application has been around for some time now, but somehow evaded my attention. My limited imagination makes me say “think of it us Dropbox hosted on the server in your basement”. Of course, it is much more than that. You can even get a […]

Removing Chef Server Installation

Igor — Wed, 18 Dec 2024 14:01:37 +0000

Originally published December 19, 2018 @ 11:41 amJust a quick note on how to completely remove (more or less) Chef server installation from a CentOS/RHEL box. There are a bunch of bits and pieces all over the place and it took me a few minutes to figure this out, so here it is: chef-server-ctl uninstall […]
