Indoor Wi-Fi Roaming with OpenWRT

A few months after writing up the units and moving the house over to , I ended up revisiting the one bit I had deliberately waved away as “good enough”: roaming.

A real house, with a mix of phones, tablets, laptops and a few stubborn IoT things that insist on staying in 2016, has… issues. But they’re not always obvious, and given we’d both upgraded the 5GHz band and changed the locations of the access points, it took a while to figure out where the new rough spots were.

If you’re just tuning in, I have a hard split between a legacy 2.4GHz network and the modern 5GHz one. I already had client-managed roaming and basic handoff guidance, but now I added usteer, 802.11k neighbour reports (because hostapd was not cooperating), and things are now pretty much perfect.

The long version is below, with anonymised data and enough detail for future me to remember why I did this.

Why I Did Not Merge The SSIDs

The obvious advice for roaming is “use one SSID everywhere”, and that is often correct if you’re running Wi-Fi in an office, a public venue, or generally somewhere where you don’t have (or care about) legacy devices. It is also not what I did, because the 2.4GHz side needs to remain friendly to older and slightly terrible IoT devices, which means WPA2 compatibility and a conservative setup.

The 5GHz side is where the more modern clients live, and despite losing 5GHz access for a couple of things, I was happy to move it to WPA3. So this is what things look like from a high level:

  • 2.4GHz: legacy-compatible WPA2-ish network for IoT and old clients.
  • 5GHz: modern client network with WPA3/SAE
  • 2.5GbE backhaul across four “dumb” APs
  • Zero cloud management or vendor-specific software. Nada. Zilch. Non-negotiable.

User Feedback

However, I got a few complaints that when moving about the house, iPhones, iPads and MacBooks would not switch to another AP. Since our flat is wrapped around a couple of elevator shafts and there are a few spots (like the kitchen) where tiling, pipes and tiny RF nuisances like fridges were prevalent, that sort of tended to happen a lot–and Apple devices are notorious for being opinionated about that base station they want to stick to.

The baseline seemed fine. All four APs had 802.11r/k/v-related options enabled. Fast Transition was also demonstrably happening–the AP logs had auth_alg=ft entries that showed fast transition was happening, I had installed wpad-mbedtls for “mesh” support, but roaming clearly needed to be improved.

And my setup meant it had to be improved within each band/SSID, not across bands. Cross-band roaming is the client’s job, and many clients are not especially good at it.

Adding usteer

But two things stood out:

  • There was no steering daemon installed. Clients were making all roaming decisions on their own, which usually means they hang on to a far-away AP until their signal is frankly embarrassing.
  • rrm_nr_list was empty on every radio. In other words, even though 802.11k was enabled, hostapd was not exposing neighbour reports to clients, so… no real way to steer anything.

So I installed usteer and its LuCI companion package on all four APs, enabled it, and left the initial configuration at defaults:

opkg update
opkg install usteer luci-app-usteer
/etc/init.d/usteer enable
/etc/init.d/usteer restart

The default configuration is minimal: LAN gossip, syslog enabled, IPv6 disabled for the daemon (because, for reasons, I don’t trust our current ISP router to do anything reliably except act as an ONT), and a moderate debug level. That was enough for all APs to see one another and exchange client data, which is exactly what I wanted.

However, the 802.11k neighbour list wasn’t being populated. After poking through the OpenWRT forums, I realized the missing piece was static-neighbor-reports, which is one of those tiny OpenWRT packages that does exactly what it says and nothing more.

Each AP can generate its own 802.11k neighbour report element via:

ubus call hostapd.<iface> rrm_nr_get_own

But clients only get useful neighbour lists if each AP is told about the other APs. So I generated per-band lists and installed them per AP:

opkg install static-neighbor-reports
/etc/init.d/static-neighbor-reports enable
/etc/init.d/static-neighbor-reports restart

The important detail is that the reports are band-specific: 2.4GHz radios only advertise 2.4GHz peers, and 5GHz radios only advertise 5GHz peers. No cross-band mixing, because the two networks intentionally have different SSIDs and security settings.

After that, every AP had three neighbours per radio, usteer had AP/client state, and hostapd has explicit 802.11k neighbour data to hand to clients that ask for it.

What Changed

The first comparison is a little boring, but useful. Here is the 2.4GHz SNR before and after the change (this, like the other charts here, was generated from data):

2.4GHz SNR over the week
2.4GHz SNR over the week

2.4GHz SNR: pre-rollout vs latest
2.4GHz SNR: pre-rollout vs latest

There is no miracle here. 2.4GHz remains 2.4GHz–crowded, noisy, full of junk devices and crowded by all my neighbors. Two of the APs improved or stayed roughly level, two got worse in the sampling window, and I have zero expectations about ever clearing this kind of congestion without moving to the countryside.

The 5GHz side is more encouraging, even if you do need to know when we were near which AP at what time when you look at active bitrates:

5GHz bitrate over the week
5GHz bitrate over the week

The interesting part, though, is that at least between two APs, there was a noticeable shift in usage–which seems to reflect where clients should be registered in practice:

5GHz bitrate: pre-rollout vs latest
5GHz bitrate: pre-rollout vs latest

But the best sanity check is the sticky-client view, because that is what started this in the first place:

Sticky-client check
Sticky-client check

The number of merely weak clients did not disappear–one extra client fell below -75dBm in the later sample–but the very weak clients went away. That is the bit I care about: the previous -90dBm-ish sticky associations were gone in the later check, which seems to indicate clients are not getting hung up on their previous AP and are indeed roaming.

Caveats

A single sample is not science, and Wi-Fi is a swamp of client decisions, radio noise and domestic entropy. I also saw one new Fast Transition log entry after the rollout:

FT: Missing required pairwise in pull response from a peer AP

That happened once in the latest check. It is not enough to call the setup broken, but it is worth watching–especially because SAE and FT have enough moving parts that I would rather trust logs than assumptions.

Going Forward

I will be keeping an eye on this over the next few weeks… somehow. I got an LLM to do the Graphite queries and chart scripting for me, and ain’t nobody got time to build dashboards only I would look at, but the metrics aren’t going to go away and the stable config lives in my local instance now, so there’s really no excuse not to do a spot check in a few months.

But I really like my Cudy APs. No cloud controller, no meshing, no mobile app and no secret sauce. Just OpenWRT, collectd/Graphite, and the odd ssh session to check configs.

That is still the main thing I like about this setup: when it gets weird, it gets weird in ways I can inspect.

Notes for May 17-24

My sinuses are still giving me grief, but this week was much more successful at pretending to be enjoyable, at least. For starters, we watched Project Hail Mary, and it was every bit as good as I would expect it to be, which is very rare in movies these days.

Meetings Suck More In Summer

Insomnia seems to be fading, but as the weather improves, the time windows for leaving the house and enjoying exercise before the heat kicks in have become narrower and are in full-on collision with typical meeting schedules, and that has become a major drag on my optimism since I have to wonder why, as an industry, we haven’t really solved meetings.

The technology is fine–it’s a culture problem. Stand-ups, project syncs, account planning, everything requires far too many unproductive meetings that just accrete overhead because a) people don’t really prepare for them and b) people don’t have time to prepare for the meetings that matter because of all the other meetings.

And, of course, everyone thinks their meetings are the ones that matter.

Couch Time

Either way, I’ve finally started having more enjoyment off-work. A good deal of it stems from the fact that I can now use piclaw as an interactive notebook across all of my projects and just scribble on a tablet screen (including annotating images and text to feed back into the agent).

Using piclaw on the couch
Using piclaw on the couch

I have already gotten most of the annotation experience to work on my as well (and with a local agent to boot), so I’m starting to wonder when OpenAI or Anthropic will pick up on this (neither of them has a decent tablet UX, and they clearly don’t seem to care about that).

In the meantime, I’m looking for an Android tablet that would be at least as good as a Samsung one, but without any of their UI junk–the TCL NEXPaper ones seem very interesting, but it’s apparently impossible to reach any of their marketing people…

Joking Around

One of the things I’ve been playing with a la longue is Joker, my souped-up version of a runtime for . Well, go-joker now has a proper notebook interface–cells with run states, rich outputs, inline SVG rendering, WASM-backed bitmap demos, and a parallelised Mandelbrot cell that renders fast enough to feel interactive.

This is another step towards the -for-code thing I a few weeks ago, except it’s running in a Clojure interpreter that I developed in another notebook-like interface:

go-joker notebook with Mandelbrot rendering
go-joker notebook with Mandelbrot rendering

The irony of constantly working on notebooks within notebooks is not lost on me, but it does look very good right now.

Inference Hardware

I just got a SpacemiT K3 board to test, which is both my and a refreshing take on the ecosystem, because a) it was zero hassle to set up b) came with 32GB of RAM and c) has a promising (if weird) NPU arrangement that I fully intend to exploit, even if (as usual) source code and documentation is a little sparse.

On the GPU side, I’ve been trying to shoehorn a Qwen model with MTP and KV cache optimizations into my 12GB 3060 in parallel (without any real usable solution yet), so alternative hardware is even if (at least right now) it poses a completely different set of problems to solve.

Emulation Progress

My long-delayed build draws near–after pondering my options I ordered the mini-macintosh PCBs and parts (5 of them, even though I only have 2 Maclocks) and have been poking at the Mac JITed emulators a bit, but I got sidetracked into getting the MMU to work in previous-jit and… I haven’t really paid much attention to any of the other bits.

I did try to get ios-linuxkit to run faster through a variety of strategies, but the truth is that performance work on interpreters is humbling–most ideas that sound good measure worse, and none of it panned out except some iOS fixes–terminal input latency, soft keyboard lag, DNS fallback, and iPhone canvas scaling.

The gap between “works on my iPad Pro” and “works on an iPhone” is always wider than expected, and in this case I am actually considering removing ghostty-web from the iPhone version given the added overhead.

Logitech Combo Touch: Four Years Later

I think it’s time for an update on my iPad Pro M1 and, most importantly, the Logitech Combo Touch I got for it. Think of it as a long term review of sorts.

In short, I bought another Combo Touch–the old one was falling apart.

Disclaimer: I paid for this with my own money, as I did the first one, but Logitech did offer me a discount. As usual, this article follows my .

The Good Bits

I had originally chosen the “sand” color, which was a sort of calculated bet–I wanted something different from the traditional black, and mentally prepared myself for it to accrue stains or dirt over time.

Guess what, it really didn’t. I guess it will look slightly darker and dingy if put alongside a new one, but I have zero complaints about the fabric-like parts and can only find a very small (sub 5-mm) stain if I look really hard. Maybe I was lucky, but those bits still look great.

I have also had zero issues with the keyboard. Yes, it has short travel, but it is effectively full size, the international English layout is excellent for coding, and it has been extremely reliable over the past four years. The only key with a (cosmetic) issue is my S key, which was slightly marred by a stray solder blob.

And the trackpad is simply sublime–it is the best non-Apple trackpad I have across all my hardware, not to mention it is luxuriously large for a tablet trackpad.

The Bits That Fell Apart (Literally)

Over the years, the speaker slots (which are effectively thin strips of rubbery plastic) started deforming. First subtly, then to the point where they are now either broken or completely deformed:

Deformed speaker slots on the old Combo Touch
Deformed speaker slots on the old Combo Touch

This does coincide with how I hold it for writing in both landscape and portrait mode (the inner cover edge is also flaking off on the bottom left side in portrait orientation), but… I’m at a bit of a loss as to why this wasn’t factored into the design somehow.

Buying Another One

Unfortunately, Logitech does not offer the possibility to buy only the cover, otherwise I would have kept my current keyboard.

And there were no refurbished ones shippable to Europe either (for whatever reason), so I ended up reaching out to support and then buying an entirely new “Oxford grey” one (which was effectively the only color available).

Oxford grey Combo Touch next to the old sand one
Oxford grey Combo Touch next to the old sand one

The new one is physically identical as far as I can tell–same connector, same kickstand, same key layout, same excellent trackpad.

Which means everything I still applies, and I won’t repeat it here. What I’m more interested in this time is whether this one will last longer without deformation.

I have my doubts, of course.

TIL: Noctalia Shell Lock on Suspend

This is a little bit of follow-up to my – I keep using it routinely (especially when we travel for leisure) and love the little thing to bits, but I’ve been wanting to run it mostly on power saving mode to reap the most benefit out of the hardware (and battery, of course), so I started looking at desktop environment alternatives.

Yes, I could already get a full afternoon (and then some) out of it, but Apple Silicon has spoiled me as far as battery life expectations go, and has a little bit too much baggage for that kind of extended use.

Since I spend 90% of my time on it writing or coding and still have a penchant for keyboard-driven desktops, I initially switched to Fedora Sway Atomic (gotta love being able to swap environments with a single command…), but later installed Niri and Noctalia Shell because I really like both the idea of a scrolling window environment and the sheer polish of the whole thing–even if there are some rough edges here and there.

I am very happy with it, and writing plugins for it is trivial:

I hacked together a Bing Wallpaper plugin in 30m
I hacked together a Bing Wallpaper plugin in 30m

The one thing that annoyed me to no end, though, was locking on suspend, which Noctalia Shell should do but apparently doesn’t in , so I had to resort to two hacks:

Locking on Lid Close

The first was adding a switch-events block to the Niri config to trigger the lock screen when the lid closes:

switch-events {
    lid-close {
        spawn "qs" "-c" "noctalia-shell" "ipc" "call" "lockScreen" "lock"
    }
}

Idle Lock via swayidle

The second was setting up a swayidle systemd user service to lock after 5 minutes of inactivity and suspend after 10:

[Unit]
Description=SwayIdle Service
After=graphical-session.target

[Service]
Type=simple
ExecStart=/usr/sbin/swayidle -w \
    timeout 300 'qs -c noctalia-shell ipc call lockScreen lock' \
    timeout 600 'qs -c noctalia-shell ipc call sessionMenu lockAndSuspend'
Restart=on-failure
TimeoutSec=30

[Install]
WantedBy=graphical-session.target

This last one feels extremely gauche and I hope to find a better way, but I guess this comes with the territory. I don’t really care about having a trendy Wayland desktop (I just want a dead simple one with a bit of polish), but I hope this kind of hacks won’t be necessary for much longer.

Oh, and of course I set gsettings set org.gnome.desktop.wm.preferences button-layout 'close,minimize,maximize:appmenu' to match macOS decorations.

Apple Papercuts

I know this blog has strayed a fair distance from its Mac-centric origins, but I’ve been keeping a mental list of all the things that are broken, missing or inexplicably neglected in ’s software, and it’s gotten long enough that writing it down feels like a public service1.

This isn’t about or grand design failures–those are well documented . This is about the small stuff. The papercuts that, individually, you learn to live with, and collectively make you wonder whether anyone at Apple actually uses their software.

Despite the somewhat surprising length of this post after stitching together all the notes, I’m actually focusing on the things I hit every week (not trying to put together an exhaustive catalogue), and others will have their own lists–and that’s part of the problem.

Mail

is the first app open every day and the one I find hardest to defend, and I’ve been defending it for twenty years (longer if you remember the original NeXT mail client).

The broader story is one of abandonment. used to be extensible–there was a plugin API that third parties used to build genuinely useful tools (GPGMail, SpamSieve, Act-On, all manner of filing and productivity helpers), and I used it to, among other things, have HJKL keybindings.

Apple deprecated that API, replaced it with a (much more restrictive) MailKit surface in 2021, and proceeded to lock MailKit down so hard that barely anyone shipped an extension.

And then they quietly stopped mentioning it. The result is that Mail is now less extensible than it was in 2010.

In particular, in this age of desktop AI agents, I come time and again across the fact that support in Mail has been left to rot. I wrote about via AppleScript years ago, and even then it was a workaround for missing functionality.

Today the dictionary is unchanged, the bugs are unchanged, and the “Apply Rules” menu option–which used to let you re-run rules on selected messages–no longer works consistently on multiple selections, if it works at all.

And searching for messages is such a mockery of a user experience that I’m not even sure how to describe it–suffice it to say that it never searches solely inside the folder I’m in and that it often fails to find messages that I know are there, even with the most basic criteria.

Mail on iOS Is Just Consistently Worse

And then there are the basics that have simply never arrived on iOS:

  • There is no way to filter messages on an . Not “limited filtering”–none. You cannot create a rule, you cannot sort by sender, you cannot batch-select by criteria.
  • Smart folders don’t exist on any version (no, the stupid Categories thing doesn’t count). They’ve been on the Mac since… 2004?
  • And, of course, there is no way to have Mail rules sync from the Mac to iOS. For a company that talks endlessly about ecosystem coherence, this is bizarre.
  • Download progress is opaque. When Mail is pulling thousands of messages from an IMAP server, the feedback is either nothing or a tiny spinner.
  • in Mail amounts to a summary button that occasionally produces useful one-liners.

There’s no smart filing, no suggested rules, no priority inbox–nothing that would actually reduce the cognitive load of managing email. had most of this a decade ago.

Time Machine

I wrote , and if I had the patience, I could probably write twice as much.

But I’ll just add that the performance is abysmal if you have thousands (or millions) of small files, and that things like asimov (or manually setting the right extended attributes manually for excluding development folders, something I routinely forget to do) shouldn’t exist, because it should work properly in the first place:

  • It should have much more transparent progress indications
  • It should never fail silently
  • It should recover gracefully from failures
  • It really should suggest automatic exclusions and have a proper UI that is not “Add this huge top-level folder” for exclusions

Again, this isn’t rocket science. I installed Borg Backup the other day on some of my Linux VMs, and it is so good that it defies explanation how Apple still hasn’t gotten this right.

Craig Hockenberry recently wrote up an experience that captures the problem perfectly: his iPhone’s Spotlight index corrupted, search stopped working across App Library, , Notes, Messages and Settings, and after trying every remedy he could find online–forced restarts, language changes, toggling Siri, developer mode reindexing–the only “fix” was a full device backup and restore.

Which took hours, broke Apple Pay, reset FaceID for two dozen apps, wiped TestFlight builds, and generally made his life miserable for days.

On the Mac, rebuilding the Spotlight index is a one-line terminal command that somehow I keep not memorizing despite needing it once a month. On iOS, that affordance doesn’t exist.

“It just works, my ass” was Craig’s summary, and it’s hard to improve on it.

Search on is slow, inconsistent, and returns incomplete results across every app that relies on it. On it’s marginally better but still loses to most third-party tools, solely because Spotlight completely made a mess of the user experience and Finder, well, can’t even find itself sometimes.

Calendar

This, again, is something that I come across every single time I need to manage personal time, and that is essential if we want any form of serious AI assistants to work (or integrate with Apple stuff).

But I’ll cut right to the point: the app has barely changed since iOS 7, and the parts that have changed are worse.

  • Event metadata parsing is broken. If someone sends you a calendar invite with a video call link, Calendar will sometimes pick it up, sometimes not, and sometimes create a phantom “location” that’s actually a URL fragment.
  • There’s no way to see a compact list of upcoming events without also seeing the full calendar grid.
  • Calendar sharing within a family is functional but graceless.
  • support is just… not there. It sort of works, but ever since Apple decided to move both Calendar and Reminders to CloudKit (or whatever), all you will get (for Reminders, at least) are the leftover entries that they left in the store before the migration.

Oh, and need I mention that Siri is terrible at calendar operations, including the extremely basic “at what time did my wife book dinner”?

Automation

I know. Most of the parts about some apps above are also about automation, and I did post about this in my , but it deserves a dedicated entry because in this age of Codex and Claude being able to control your desktop, it rankles.

  • actions break between OS versions. Not occasionally–routinely.
  • is unmaintained, and despite what I wrote earlier, is now presumed dead.
  • There is no cross-platform automation story whatsoever. No, Shortcuts is not useful there, save for the laudable exception of being able to use my iPhone to automate switching watchfaces (which is something very few people are likely to use).
  • Accessibility sort of works, but it is so clunky in practice that some of the workarounds I’ve seen implemented in Claude and Codex border on the hilarious.

The bottom line, for me, is that Siri Shortcuts integration is shallow compared to what offers through intents, or what Windows offers through COM automation (or even Win32, which surprisingly still works so well that it took me 15 minutes to do an agent tool).

Virtualisation

In keeping with Apple’s inability to make the iPad truly useful, has no hypervisor support today–it was removed in iOS 16.4, and nothing has effectively replaced it since. The result is that you can’t run a Linux VM on an iPad, and you can’t run Docker containers on it either, which means that the entire ecosystem of local LLMs, coding agents, development environments and monitoring tools that I rely on for work and play is completely inaccessible on the iPad.

has had Hypervisor.framework since… Yosemite, and Apple Silicon Macs run VMs beautifully–but on and , the entire concept doesn’t exist, and we are forced to run half-assed emulators like (which I’ve been banging on for a month as a way to prove my point).

This matters to me because a huge amount of the software I use daily–local LLMs, coding agents, development environments, monitoring tools–runs in containers or lightweight VMs. I can do all of this on an EUR 50 ARM board running . I cannot do any of it on an EUR 1,400 iPad Pro with an M4 chip, without jumping through hoops to get AltStore to run on it so that can pretend it has proper virtualization.

I know that Apple doesn’t care about this now that they feel buoyed by the ’s runaway success, but I am actually looking forward to trying out a solely because Google has reasonably decent support for running Linux userlands on ChromeOS and Android, and I want to see how that compares to the iPad’s non-existent support.

Home Automation

I could possibly write a book about this by now, considering that I’ve been at this . could be so much better, but it is also a part of the Apple experience where the gap between promise and reality is most painful.

Yes, is coming, etc., etc., but a new protocol will never solve any of the shortcomings of the Home app:

  • Scene chaining doesn’t exist.
  • If-this-then-that logic is barely functional.
  • Presence detection is flaky and not granular enough for room-level logic.
  • There is no scripting layer. can trigger HomeKit actions, but HomeKit automations can’t call Shortcuts.
  • Adaptive lighting is half-baked.
  • Multi-home support is a mess.

I’ve papered over most of that with and Homebridge, and of course Home Assistant can do all of the above, but, again, my main point is that it shouldn’t need to exist for people who’ve bought into the Apple ecosystem.

At this point, Apple should just buy Homey and can their entire HomeKit stack.

Apple Watch

The Watch deserves its own entry because it’s the device where Apple’s failure to prioritise timekeeping is most absurd, and with the rebirth of , I was reminded of how awesome smartwatch UX can be and how Apple never even got close.

In particular, the “Smart” Stack (the thing you get when you swipe up from the bottom) is never aligned with what I actually want to see, or what is up on my calendar.

The ’s timeline view remains the high-water mark for watch UX–one button tap, chronological day view, no widget carousel.

Apple’s Calendar app on the Watch tries to replicate the iPhone calendar grid on a 45mm screen, which is about as useful as reading a newspaper through a keyhole.

A watch should be the single best device for time-aware context. Instead of building a timeline, Apple built a widget carousel.

iCloud and CloudKit

I once spent a week building a client to talk to iCloud Reminders and Calendar, and the experience was a masterclass in Apple’s backwards-compatibility approach: it works, except when it doesn’t.

  • Newer Reminders lists silently migrate to CloudKit and disappear from CalDAV entirely.
  • Apple Notes is completely gone from IMAP–all content is now behind CloudKit’s protobuf CRDT format, which Eric Migicovsky recently reverse engineered
  • Calendar event recurrence expansion doesn’t work properly through CalDAV.
  • App-specific passwords are required if you want to have third party clients sort of work, but limitations are documented nowhere.

The pattern mirrors a lot of my gripes about the original iCloud services: Apple builds new infrastructure, migrates data silently, leaves old APIs running but progressively useless, and provides no supported path for third-party access.

Terminal

Yes, it got updated recently. No, it is neither good nor fast nor consistent when you use daily, and that is why I use . Like a lot of other core Mac tools, I have feelings about it, some of which I cannot express politely.

Developer Experience

I write because I have to, not because Apple makes it easy.

The language itself has been through enough breaking revisions that code from three years ago often won’t compile without changes. is worse–views that worked on iOS 17 already behaved differently on 18 and now seem broken in 26, and the abstraction leaks the moment you need anything beyond a list and a navigation stack.

The result is a UI framework that feels modern in tutorials and feels like debugging a black box in production. I’ve lost count of how many times I’ve had to drop to UIKit to work around a SwiftUI layout bug that, once I start searching for it, I realize has been reported for years and yet nobody at Apple acknowledges.

And then there’s the $99/year developer fee, which Apple charges you for the privilege of running your own code on your own hardware. Not to publish on the App Store–just to run an app on a device you already paid for. The certificate expires annually, and if you don’t renew, your sideloaded apps stop launching. In 2026, on hardware I own, I need a subscription to run my own software.

The App Store itself is a whole separate set of papercuts–review delays, opaque rejections, the 30% cut, the inability to distribute updates outside the store–but those are well-documented grievances.

The one that gets me is simpler: the entire developer toolchain assumes you are building a product for sale, not a tool for yourself. doesn’t have a “just let me run this on my phone” mode that doesn’t involve provisioning profiles, entitlements, and a certificate chain.

Until I started using , every personal project started with ten minutes of ceremony. Now I never even open .

Phone Size

I still have an in a drawer, and every time I pick it up I’m reminded of what a phone that fits in your hand actually feels like. It’s delightful to hold–thin, light, one-handable without gymnastics, and the screen is perfectly usable for everything I actually do on a phone.

Every iPhone since has been bigger, heavier, and harder to use one-handed, and the Max/Plus variants are actively hostile to anyone with normal-sized hands or normal-sized pockets. Apple keeps making the screens taller and the bezels thinner, but the fundamental ergonomic regression–that phones stopped being things you hold comfortably and became things you grip–has never been acknowledged, let alone reversed.

The iPhone SE was the last concession to people who wanted a small phone, and Apple killed it. The Mini lasted two generations before being quietly shelved. The message is clear: you will hold the slab and you will like it.

The Pattern

Every one of these is fixable. Most have been fixable for years. The pattern isn’t technical inability–it’s neglect.

Apple has the engineers, the money, and the platform control. They’ve chosen not to, repeatedly, and I suspect writing about it won’t make any difference, but as someone who has been using Macs since the System 6 days and writing about OSX here since the very beginning, I like to keep a scorecard.

And right now, it’s neither looking good nor reassuringly future-proof, unless, of course, you happen to love Liquid Glass.


  1. And, as it happens, two weeks of insomnia and allergies provided both the time and the inclination to write it all down… ↩︎

Notes for May 10-17

The weather has gone a tad cloudy again, which provided me some relief from my allergies–but not enough for proper overnight rest, so yet again I arrived at Friday afternoon totally exhausted.

Still, the early mornings were pretty decent to get some writing and coding done, and my sinuses are indeed marginally better.

Despite having wasted hours of my week trying to , I still managed to churn out and polish the default terminal app a bit (it now has nicer theming, font settings and external folder mounts), and I’ve been instrumenting the emulator to do hot-block statistics and adding a proper profiling layer for deciding on future optimizations.

And I have picked up a few apps to test it on. The first is Terax, a little “AI terminal emulator” written in and Tauri, which works pretty well (with a few bugs due to the different ways it uses PTYs):

Terax AI terminal running in ios-linuxkit
Terax AI terminal running in ios-linuxkit

Code will be up soon–I want to do a bit more testing and polish both the integration and the UX, since Tauri made a bit of a mess of the iPad layout.

Tiny Macs

I’ve been neglecting my ARM64 SheepShaver build, but I did find the time to fiddle with the code–I got it to build for the displays I had a few weeks back, but the resistive touchscreens were so awful that I immediately decided to order capacitive (and bigger) ones:

Cydintosh on two CYD displays
Cydintosh on two CYD displays

I’m still playing around with these in my own fork, and will have a bit more to share soon.

Piclaw is Going Visual

Piclaw visual UI

Thanks to a colleague of mine, piclaw is getting a new “visual” UI–and yes, I know what it reminds you of. It’s great, and it will be the default for the upcoming desktop builds, which will be a good test of my patience for packaging and testing stuff.

I should probably have spent less time at a computer this weekend, though…

Announcing ios-linuxkit: Linux on iPad, the Hard Way

I’m done waiting for Apple to fix things. And one of the things I think should exist is a decent way to run Linux binaries on my iPad.

And after almost six months messing about with ARM emulation in various forms, I can finally do something about it.

Put bluntly, the lack of hypervisor support on should be an embarrassment to Apple–an EUR 1400 iPad Pro with an M4 chip can’t run Docker, can’t run a VM, can’t do any of the things I do daily on an EUR 50 ARM board. Apple has the hardware support, the kernel entitlements, and has chosen to keep it locked away.

ios-linuxkit is my answer to that, or at least as much of an answer as you can get without Apple’s cooperation. It’s a Linux runtime for that provides a working AArch64 userland on iPhone and iPad–shells, compilers, package managers, language runtimes, the lot–without JIT, without RWX memory, without MAP_JIT, without any of the things Apple won’t let you have.

The base is the ish-arm64 branch of iSH, which implements a threaded-code interpreter (they call it “Asbestos”) that translates ARM64 Linux instructions through precompiled gadget dispatch. No runtime code generation means no App Store policy violations, which means it can actually ship. The trade-off is performance–you’re not getting native speed, you’re getting “fast enough for a shell and some compilers.”

It’s fast in human terms, although my use of and Bun mask a lot of the underlying limitations.

Why Now

The timing comes down to converging interests: I have been deep in emulation land since , and even though the ish-arm64’s “gadget” emulator is quite a different beast from the naïve block-level JITs I’ve been bolting onto BasiliskII and SheepShaver, I have been developing all of them on the board I have been testing for a few months, so they share roughly the same approach:

  • Bolt on a VNC server (or an emulated console) so I can connect to it from my iPad
  • Build out several test harnesses (build, base smoke tests, tracing harnesses and automated application testing)
  • Figure out what to do (this is the hard part, and I’ve learned quite a bit across the various emulators)
  • Figure out where it breaks (, , etc.) and why
  • Hand out the drudgery (like test runs and automated fixes) to a piclaw instance in clearly defined piecemeal specs so I get nice reports and debugging output I can review in a clean web UI

I wouldn’t have had the time or energy to do this without Codex, but I certainly wouldn’t have been able to do it without the as a test bed. Having an ARM 12-core SBC with 16GB RAM I could devote to this, despite a tad constraining (I would have preferred 32 so I could run more builds and test matrices concurrently) was a major enabler here.

What I’ve been doing with it

The fork started as a bring-up exercise, but has turned into something more focused: making the runtime stable and tested enough that you can actually develop on it. The current validation gate has 82 core tests passing on Alpine ARM64, with workload coverage across , , Bun, Node, , , Zig, and a few others.

And since I’ve seen quite a few people trying to run AI coding agents on iOS, there’s a separate set of AI CLI harness tests that installs, runs and does cursory tests on most current agent tools (spoiler: Claude Code was a complete and utter pain to get to run. Everyone else’s mostly “just worked” after a few cycles of JS runtime/kernel call cleanup passes, theirs was just broken).

The harness testing is AI-driven–I pointed piclaw at it with a custom gdb skill and let it grind through failures, fix them, and re-run. The strategy is mine (which syscalls to prioritise, what the “gadget” fixes should look like, where to invest in performance), but the mechanical detection/fix loop is the kind of thing that would have taken months by hand.

Why this matters

Because I think it is a thing that should exist, yes, but also because I want to run things like gi (which is still WIP) on my iPad.

Especially binaries, which never ran in the original iSH. And despite my love for remote sessions, I don’t want to run all of it on a server, nor via a UI proxied from somewhere else–I want to do some of it locally, in a terminal, with my workspace on the device.

Bun, V8 and Go work. Alpine’s apk means I can easily get pretty much every single CLI tool I need to work too, without the compromises (which I still love, by the way) imposed. And since I have been hacking away at my own flavor of in rcarmo/ghostty-web, I was able to swap the dated iSH terminal with something that looks right.

It’s not fast (well, it is, much faster than the original, but not native fast). It’s not a replacement for HyperKit on iOS (if we ever get it back). But it’s mine, I can fix it and make it faster to some degree, and works for me.

And since I have zero intention of bringing it to the App Store myself (or even paying Apple $99 for the privilege of running it on my own hardware without plugging my iPad into my laptop weekly, which is something the EU should really ding on Apple for), I am going to maintain it and add more fixes, keeping it open source so that other people can build better, more polished tools.

You’re welcome.

Update, May 19: I’ve since and have started poking at the Asbestos emulator to see if I can both speed it up and fix a few more corner cases around compilation, which is still very slow.

Unexpected Synology Woes

Last weekend my decided, for some unfathomable reason, to stop working after I took it out of the closet, dusted it and put it back, and I have feelings about it.

In fact, I’ve had them throughout the whole week, because it’s taken forever to get most of my home services up again.

Fortunately, my home automation and a few other things are spread among my nodes, but I had a bunch of things running on that NAS, and I wanted to document what happened because someone else might have the same issues I did and end up here.

Symptoms

The machine booted up (power LED initially blinking, solid green status LED, disk activity almost immediately), but would not show up on the network.

Both LAN interfaces would be up, but issued zero packets. No DHCP requests, no link-local addressing, not even replies to arping (and yes, I knew the MAC addresses of the machine, because that’s the kind of thing I keep tabs on). I plugged in my MacBook and my on each interface, rebooted, and saw… nothing.

tcpdump saw nothing at all. I thought it might be some sort of OS glitch (which is why I tried both laptops), but no luck.

So I tried to reset it to factory configuration. You have two reset levels, the first of which only resets your admin password and network settings, the second has you reinstall the OS without losing data.

But nothing worked, and ’s tooling just couldn’t find the NAS or connect to it.

Recovery

The first thing I did was set up Virtual DSM on borg to see if I could, in the direst of emergencies, access our off-site backups. That sort of worked, but the experience was so fiddly that I was reminded of all of HyperBackup’s pitfalls in one fell swoop–most notably that I effectively need a Synology to get at that data, which is not something I want to rely on.

Yes, there is a HyperBackup desktop application. No, it did not work for me–it apparently expects you to download backup files from the cloud to your local machine, and I need to be able to directly restore files from Azure, period.

After filing a ticket with Synology about my unresponsive system, they sent me an AI-generated troubleshooting list, in the middle of which was a step I could not find anywhere in their online documentation: booting the machine without any disks.

That apparently also automatically reset settings (which is, in retrospect, weird, because it feels like something should be stored in the chassis for this kind of emergency), and I was finally able to discover it on the network, reset the admin password, reconfigure the network, etc.

So if you have the same symptoms, this might save your day. And, as it turns out, be the prelude to an entire week of pain, because mine spent the past five days or so grinding through data scrubbing. Because that is a thing it felt like doing, and I’ve been coping with the fallout since then–extremely slow access, very slow response times as I tried to double-check services and settings, etc.

What Didn’t Work Right

First of all, all my containers were gone. Container Manager, for some reason, does not preserve any settings in this scenario, and if I didn’t have installed and a copy of (most of) my stacks in , this would have been enough for me to never again run containers on a Synology.

As it was, I was able to point piclaw to the machine and have it reconstruct all critical services in a few hours (it would have been much faster if it wasn’t doing scrubbing). And, as it turns out, there was also enough residual info in the underlying Docker daemon itself to fill in most of the gaps.

But barring that, there were a bunch of things that made recovery a pretty stressful endeavor:

  • The mobile apps (DS Finder and the like) were useless in finding or diagnosing the issue at every step.
  • The web site did not list disk removal as a troubleshooting step (at least not that I could see, since it went straight into the dual-step reset procedure).
  • The timing documented for holding the reset button for reset 1 (4 seconds) was not accurate. It was more like 20, and I feared for a moment I might end up triggering reset 2, which would require reinstalling the OS.
  • Synology’s desktop tools are, to be brief, very poorly maintained and look like something out of the 90s, even down to the Windows look on macOS.

So even for an “appliance” NAS, the experience could be much better.

Let’s Have an Adventure

Resetting the configuration had zero impact on my data–at least so far as I can tell. Shares, users, all the regular stuff was preserved, and after a few glitches with cloud backups (because disk scrubbing made them fail overnight twice), everything seems in order.

But since the machine spent so long simultaneously scrubbing and swapping as I tried to restore services, it’s clear that I cannot rely on it for interactive use anymore.

Synology doesn’t really let me upgrade RAM on the thing (you sort of can, but it’s already capped at the maximum RAM the J4125 can officially support), so I’ve started removing stuff from it–most of the Docker services I’ve been running there for years are now moving into microVMs or s running elsewhere, and are either going to use the Synology as a “dumb” NAS and mount storage directly, or be backed up to it using Borg Backup Server (which is going to be the only new Docker container running on it).

I’ve already moved and off it, and having them run (even with very constrained resources) on separate microVMs in an N150 makes a world of difference–so much so that I have to wonder why I put up with the J4125’s slowness for years.

I set to snapshot both VMs daily (and added a temporary direct-to-cloud backup), and am now slowly moving the rest. Or, rather piclaw is doing that. I had it draft a plan to group containers and create target VMs/LXCs, and the agent is now merrily ing data and container configs out of the Synology.

Mid-Term

After the dust settles, I am going to move all of my backups out of the Synology ecosystem–I currently rely on HyperBackup to back up my data to , but the recovery attempt was so off-putting that I am going to look into using directly to Azure.

Backrest looks like a nice way to do that, with the added benefit that restic backups (which I have already been using for years) seem to work better with Azure storage tiering (and thus might even be cheaper in the long run).

The Local AI Moat

Regular readers will know that I’ve spent most of the past two years shoehorning LLMs into single-board computers, partly as a learning exercise and partly because there are lots of local/”edge” applications where semantic reasoning (no matter how limited) and “interpretation” of sensor data are actually useful.

Notes on GPT 5.x Model Regressions

I’ve been getting annoyed at constant code regressions in piclaw for the past few weeks. Something was off–even after bumping the test suite to the point where it catches most mechanical errors, gpt-5.5 kept making unrelated edits to code that should have been left alone, and I was getting really annoyed at babysitting it.

Apple, Still

I have been having feelings about lately. This blog may have drifted a fair way from its original focus on , but I am still, first and foremost, an Apple user – just not an exclusively Apple user, and perhaps not even a particularly obedient one anymore, since I use both Windows and every day and have grown used to judging platforms by what they let me get done rather than by whatever story they are trying to tell about themselves.

The Orange Pi 6 Plus

This was a long one–I spent a fair bit of time with the Orange Pi 6 Plus over the past few months, and what I expected to be a quick look at another fast ARM board turned into one of those test runs where the hardware looks promising on paper, the software is wonky in exactly the wrong places, and you end up diving far more into boot chains, vendor GPU blobs and inference runtimes than you ever intended.
