dfex··on Big Breakfast Alters Appetite, Gut Health
It sounds like this study might have been funded by.... Big Breakfast.

I'll see myself out.

That program listing hit me right in the feels.

I remember when I was 6 or 7 teaching myself Applesoft BASIC and writing programs with funny (to me) little print statements all through them - when computing was just exploding with possibility.

I wouldn't have had a clue what a Fibonacci sequence was though ;)

dfex··on AI Overviews are killing the web search, and there's nothing we can do about it
What a time to be alive!

After nearly two decades of complaining loudly about deteriorating quality of Google search results and Ad injection, Google puts in AI summaries and provides 1-shot answers to >50% of queries, annihilating the advertising business in the process and TFA is complaining about that?

This is a win! I'm going to enjoy it while it lasts...

I guarantee that the minute enough people wake up and cut their advertising spend with Google, then they'll change tack again.

I wouldn't want to be hanging my career on "SEO marketing" right now..

dfex··on France dumps Zoom and Teams as Europe seeks digital autonomy from the US
It boggles the mind as to why they choose a name for this application that is very clearly a Microsoft trademark.

In understand it's also the French word for Videoconferencing, but even still...

dfex··on Floppinux – An Embedded Linux on a Single Floppy, 2025 Edition
This! I have the 14-core M4 Macbook Pro with 48GB of RAM, and Word for Mac (Version 16 at this time) runs like absolute molasses on large documents, and pegs a single core between 70 and 90% for most of the time, even when I'm not typing.

I am now starting to wonder how much of it has to do with network access to Sharepoint and telemetry data that most likely didn't exist in the Office 97 dial-up era.

Features-wise - I doubt there is a single feature I use (deliberately) today in Excel or Word that wasn't available in Office 97.

I'd happily suffer Clippy over Co-Pilot.

Surely the constraint will be the rate at which you can get them into and installed orbit, not the manufacturing rate
dfex··on Ask HN: Is there a point to maintaining distant connections on social media?
It is 100% about FOMO. The greatest pushback you'll get from anyone when you suggest voluntarily cutting off their social media accounts is that it's their way of keeping in touch/track of friends who they probably never interact with outside of watching their feeds.

Did you interact (like you know, two-way communication) with these people at any time in the last month? In the last year? In the last decade?

_Disabling_ your account, and deleting the app won't stop you from being able to log back in one day in the future if you want to look someone up, but in the mean time, you'll be living a blissful life without an ad-fuelled torment nexus simulating meaningful relationships.

Ah man, I miss the late 90s/early 00s theme of one-off mystery sites, green on black aesthetics and excessive anchor tags :)

Back in 2006 (god I feel old) there was an excellent mini-series on the SyFy channel called The Lost Room[0], which this seems to be drawing some inspiration from.

dfex··on Epic celebrates "the end of the Apple Tax" after court win in iOS payments case
I'm by no means defending the percentage they take, but I would suggest that it's a percentage because it's simple:

Pick 3 imaginary games for sale priced at $1, $10 and $100. Any one of those games could be a million download a month success, and any one of them could be a complete dud.

What flat rate would you suggest to:

* Pay the developer for their work (ongoing per sale)

* Review each game and ensure it meets store guidelines (once per update)

* Host said game regardless of how popular it is (ongoing)

* Process transactions for the game (ongoing)

The alternative would be pricing based on revenue tiers (similar to what Unreal Engine does now), which aren't known in advance and don't take global variance into account (USD$200 in Eastern Europe might be a month's salary).

Percentage is just simpler. It also means that they'd be taking a loss on every free app or in the case of Free-to-Download In-App purchase apps - until users start transacting.

dfex··on Cloudflare outage on December 5, 2025
> If everything goes offline for one hour per year at the same time, then a person is blocked and unproductive for an hour per year. > On the other hand, if each service experiences the same hour per year of downtime but at different times, then the person is likely to be blocked for closer to 100 hours per year.

Putting Cloudflare in front of a site doesn't mean that site's backend suddenly never goes down. Availability will now be worse - you'll have Cloudflare outages* affecting all the sites they proxy for, along with individual site back-end failures which will of course still happen.

* which are still pretty rare

dfex··on Ask HN: Hearing aid wearers, what's hot?
I have had fairly extensive hearing loss in my left ear for about 20-something years and finally decided to investigate options about a year or so ago.

I tried a set of Phonaks for about a fortnight, but I found them tinny-sounding (which I'm told you get used to), and their automatic mode switching (for when you walk into noisy rooms) was incredibly frustrating.

A month later, Apple dropped the Airpods Pro hearing-aid mode software update and I have never looked back. The feedback from my family has been overwhelmingly positive, which more than offsets any qualms I had about them being so visible when you wear them.

My (obviously subjective) view is that the sound quality of the AUD$400 set of Airpod Pro 2s completely smokes the AUD$5,000+ set of Phonaks, and that's before you account for all the UX niceties you get from Apple when you play in their ecosystem (virtually seamless transition between phone, computer and TV (with AppleTV box)).

The fact that you can run an on-demand hearing test on your phone for free, giving you the ability to track any decline yourself without having to front up to an audiologist is just the icing on the cake.

dfex··on Australia has so much solar that it's offering everyone free electricity
My subsidised 48kWh battery is getting installed in two weeks - and I can't wait.

I have also upgraded to a 20kW inverter (I have ~10kW of panels on the roof) so I can import or export twice as fast and I will be switching to a provider that offers wholesale pricing. Getting a guaranteed 3 hours of free power a day for charging (even in winter) is just going to be the icing on the cake.

Based on back of the envelope calculations, the battery should be paid off in about 5-6 years during which time I will have paid zero for electricity (outside of a $25/month access charge).

dfex··on My Truck Desk
Lovely story. I work out of the back seat(s) (Crew Model) of my Ford Transit pretty regularly and can relate.

I'm astonished at how productive I can be while waiting around outside a job site for late deliveries/people or even my kids music lessons for an hour or two, or when sometimes I can sit at my desk and get nothing done in the same time. Maybe it's the constraints of the time/space? I (only half) jokingly wonder if some times I'd be more productive sitting in the van in my own driveway rather than in my home office.

My "truck desk" is the rear parcel shelf/cargo blind out of a Hyundai Accent and the moulded counters fit my laptop and mouse pad perfectly. It also tucks nicely into the void behind the back seats when not in use.

I recently acquired a Vision Pro and am still coming to terms with how incredible it can be sitting in the back of my van parked literally anywhere in the country and having a full ultra-wide desktop experience that packs away into something the size of a lunchbox.

This is the cyberpunk future I dreamed of as a kid.

dfex··on Ubiquiti SFP Wizard
> The technical information for this thing seems to be light on the ground. What kind of diagnostic stats are provided? How is it figuring out true Rx/Tx power without a light meter?

The programming boxes (Ubiquiti's and others) get the Rx/Tx power from the DDM (Digital Diagnostics Module) built into most SFPs - it exposes the power levels from the receiver and transmitter inside the SFP and dumps it onto an SPI bus in a standardised way which is read by the box.

> Just insert any brand’s SFP or QSFP module, select Copy, and insert any UI module to write the profile.

It's pretty common for SFP rewrite boxes to only allow writing to that particular brand's SFP modules. It's partly a sales tactic, but also often vendor "genuine" optics will ship with a write-protected EEPROM (requiring a passcode) that stops them from being written to.

If you're after something a little more "open", Reveltronics[1] make a barebones version along with software for brute-forcing EEPROM keys.

That might be a misremember - I've been using Juniper for nearly 20 years now and only ever saw a "software bug" in 18.x that broke OEM optics, but that was quickly addressed with a patch shortly after release.

This may work in your favour - it's one of the reasons I enjoy Mastodon so much - friction is/was a little higher which kept my network small but focussed
dfex··on Designing a Low Latency 10G Ethernet Core (2023)
Genuinely curious - would 24x7 low-latency trading matter then? Wouldn't after-hours trading (for your local timezone) be happening on an exchange in another location?

Or do you mean dark pools/private exchanges that may run 24x7?

dfex··on Qualcomm to acquire Arduino
Not the OP, but have had some experience with the Arduino Opta around this time twelve months ago (Oct 24) through a professional development course I took at my local university on industrial control systems programming.

While it's nice to have exposure to PLC programming at an Arduino price point, the IDE, and PLC firmware was VERY rough around the edges. It took lots of resets and fiddling to even get the units connected over their USB serial, and you'd come back the next day and you'd have to repeat the process. Lots of "hold your tongue the right way while pressing this button". The IDE was also very buggy (though it may have improved in the last 12 months), but once you got things going, it did the job.

This is actually really exciting - it means in somewhere in the next 5-10 years we'll inevitably (well, hopefully if the cycles of history are anything to go by) see a bunch of new dissenters rise up with their associated subcultures - and the mass diffusion of the Internet will help them find their people regardless of which country they live.

Thank you - did not know this existed.

dfex··on Microsoft keeps adding stuff into Windows we don't need
The whole UI feels like it was thrown together by 15 different organisations.

I work in the networking space, and regularly tweak the IP settings to do my job.

Over the last 25 years, I have been utterly confounded as the number of clicks it takes to get from the Desktop to changing an IP address or DNS setting seemed to jump from 2 or 3 to something like 5 or 6 with all these intermediate settings pages that don't appear to serve any real purpose.

Just show me my damn adapters and let me configure them!

Win 11 seems to be moving back in the right direction, but I switched my daily driver long ago and won't be coming back.

My suspicion is that they want all the passwords on this site to match the one they use with all their other customers too.

dfex··on Flipper Zero dark web firmware bypasses rolling code security
PREACH!

Currently sitting in a control room at a greenfield manufacturing facility trying to describe why even VLANning the control network would be a good idea to some controls engineers who want a plant-wide subnet for all PLCs that will be remotely supported by 6 different vendors. The struggle is real
