Communication and Hostile AIs

March 29, 2026 | etbe

We seem to be entering an “AI” apocalypse of sorts, they aren’t going to kill us or even take our jobs. What they are doing is destroying the Internet commons by filling it with rubbish. This isn’t even real AI, just pattern matching and prediction systems, mostly LLMs.

The Problem

Scott Shambaugh’s saga of being attacked and defamed by an OpenClaw AI bot is interesting and raises some disturbing possibilities for future online discussion [1]. Imagine what it would be like if everyone who was in any way notable for free software work had 100 such bots going after them.

Dania Dumas wrote an insightful blog post about why OpenClaw is impossible to secure and why it won’t go away [2].

Bruce Schneier and Nathan E. Sanders wrote an insightful article about the AI generated text arms race [3] primarily concentrating on situations in which text that was assumed to be written by humans but was actually written in bulk by bots was performing a DOS attack on people who were reviewing it. There are many situations such as book publishing and publishing letters to the editor of newspapers where getting new material from unknown people is an important part of the job but where there are also people making low quality submissions that are almost a DOS attack at the best of times.

Currently the email spam problem continues to get worse and when LLM use increases it will get significantly worse. Email encryption isn’t viable [4]. The PGP web of trust never really worked well as it’s too difficult for most users.

The amount of “AI” generated content that’s being recommended to users on platforms like YouTube and Facebook is steadily increasing and the amount of LLM generated commentary that purports to be from real people on Twitter and Facebook is also increasing. Here’s an informative blog post by Erich Schubert about this [5].

Potential Solutions

Surrender?

One option and possibly the default option is to surrender to this and just let everything we built on the Internet over decades get destroyed. Whether to surrender is a decision that can be made on a per-service basis.

Twitter is pretty much useless anyway, I quit Twitter because Elon deliberately made it suck [6]. In my opinion this is not surrendering to what’s being done there, I’m just stopping wasting time on it and using better options. I used to have about 300 followers on Twitter and I don’t think that many of them would ever choose to stop following me, so I presume that about 1/3 of the people following me have decided to totally quit Twitter and delete their accounts. I also presume that some of the remainder have done the same as me and just kept a mostly inactive account. If Elon suddenly stopped being a stupid asshole it probably wouldn’t change anything as the value of the system was connections to others. Some people will consider my abandonment of Twitter as surrender and I accept that it’s not an unreasonable opinion. I think that the possibly 100 Twitter followers of mine who deleted their accounts surrendered.

Facebook has been becoming a worse service, it’s business model is becoming increasingly exploitative and it’s interface is designed to be addictive. It’s probably best avoided unless you really need it. The only good thing about Facebook at the moment is that Facebook Marketplace doesn’t take a cut on sales and there are some really good deals on computers if you know what to look for. Unfortunately Facebook has a large number of users who are from marginalised communities and have no other alternatives for communication. It would be good to get them migrated to other platforms.

We could just give up on a lot of general communications services and have everyone accept that good content is drowned out by rubbish and have the Internet become divided between people who accept the rubbish and those who cease using large portions of the Internet environment to avoid it.

Using Non Commercial Services

Lemmy is a good FOSS federated alternative to Reddit which also covers some of the uses of Facebook. It needs more users to get critical mass but is still quite usable. A post that might get a dozen comments on Reddit may get 1 comment on Lemmy but that one comment will be a good one. Reddit doesn’t appear to be attacked much by LLM generated content at least not yet. Even if the Reddit model proves to be resilient to LLM attack the Lemmy software can be used to replace some things that are done on Facebook,

Mastodon is a good FOSS federated replacement for Twitter, it has a decent user-base including some VIPs. While it is aimed at the Twitter use case it can also cover a significant part of the Facebook use case.

There are some other FOSS social media programs which could take over other parts of the commercial social media environment.

Generally commercially run Internet services will have a financial incentive to allow the problems to get worse so we need to rely on FOSS software, non-commercial implementations, and government services.

Web Search

For a long time Google has had a monopoly on web search, but now they default to including an “AI Overview” at the start of the results which is sometimes useful but also sometimes very wrong. You can use the search URL “https://www.google.com/search?q=%s&udm=web” to get google results without rubbish. But I presume that they will break that if it gets too popular.

Searxng is a AGPL licensed metasearch engine that aggregates results from other engines, here’s the Searxng source [7] and here’s a list of Searxng instances if you want to try one [8].

Even using meta search engines like Searxng won’t help if the original data is overloaded with spam, but alleviating the problem is a good temporary measure.

Web of Trust for the Web?

I’ve idly considered the possibility of having some sort of rating system for web pages that uses a web of trust so that you can securely use trust ratings of friends of friends etc. But given all the difficulties in using a web of trust for signing GPG key for software developers (the demographic that is most skilled at doing such things) it doesn’t seem viable.

Should we surrender the idea of having a usable public web?

In the early days of the web (before Google) it was standard practice to rely on recommendations from other people or from trusted sites to find other sites, that could be considered to be an informal web of trust. We could go back to that sort of usage pattern if Google and many of the big sites get overwhelmed by LLM generated spam.

Wikipedia

I believe that Wikipedia will be at the front lines of this battle. It’s model has always included anonymous contributions. Benjamin Mako Hill wrote an interesting blog post about research he did with Kaylea Champion into Wikipedia pages on taboo topics which have a larger portion of contributors choosing to be anonymous than non-taboo pages [9]. Wikipedia also has a long history of being abused for various reasons, one that I witnessed was someone putting false content into Wikipedia pages to immediately cite them in support of their facebook arguments. That sort of thing can be dealt with at human scale but a large scale attack by bots is a different problem to solve. Also with the recent developments in AI developing multiple web sites entirely populated for the purpose of supporting one fake entry in Wikipedia is plausible.

The upside of these attacks that I predict is that they will attract the attention of all the people who have skills related to developing counter-measures. While LLM bots are filling the inboxes of publishers with rubbish and messing up the stackoverflow comments section not a lot of people are bothered, but once the attacks on Wikipedia get serious everyone will take notice.

National AI

Bruce Schneier and Nathan E. Sanders wrote an interesting blog post about nationalised public AI [10]. While that won’t directly address this issue it will get the right technology in the hands of people who can use it in the right way.

Conclusion

This is going to be a difficult problem to solve, more difficult than the email spam problem we have been unable to solve after 30 years of working on it.

This is also a very important problem, we are currently in an age where we have access to information that most people couldn’t even dream of 30 years ago. We also have disinformation that combines some of the worst aspects of authoritarian regimes throughout history combined with the worst aspects of cult brainwashing. If we lose access to the information but the disinformation remains (or get worse) then the result will be terrible.

I don’t have great ideas for solving this. I have outlined some small ideas to mitigate things and I hope that others can expand on them.

Please write comments with any good ideas you have, or even ideas that don’t totally suck. A problem this difficult is not going to be solved in a blog comment, but a blog comment might point in the right direction.

The Death of Twitter

March 25, 2026 | etbe

At the end of last year I uninstalled the Twitter app on my phone.

In the past Twitter used to be very useful for providing feedback to large organisations. I had responses from supermarkets, chain restaurants, online stores, major computer companies, and even the IT department of a court. In recent times I have had less responses from corporations which significantly reduces the value of Twitter to me and to many other users. It seems that Elon’s management style has discouraged not only advertising but also all forms of corporate interaction. Messing up the check mark on accounts to make it harder to work out which is a real corporate

Since Elon bought it Twitter has been increasingly pushing conservative Tweets and has done little to stop bot accounts. The incidence of useful discussions has steadily decreased. I know people who have quit Twitter entirely due to opposition to Elon, I am not doing that. I finally decided to stop using Twitter in any serious way when the notifications on my phone about popular Tweets started only being about Tweets from conservative influencers and Elon. This was obviously not any algorithm based on Tweets I was liking, it was based on political decisions. I didn’t uninstall the app due to political disagreement, I uninstalled it because it was through deliberate design promoting material that any algorithm would know was something I wouldn’t either like or “like”.

I still announce new blog posts on Twitter for my 198 followers at the same time as announcing them on Mastodon and Facebook. I get the most reactions to such announcements on Mastodon, the second most on Facebook, and hardly any on Twitter. I’m wondering how long it will be worth announcing blog posts on Twitter or whether I should stop now.

I am sure that many other people are making similar decisions and this is going to affect Twitter overall.

The web site www.russellcoker.com has information on all the ways of following me.

The Difference Between Email and Instant Messaging

March 15, 2026 | etbe

Introduction

With various forms of IM becoming so prevalent and a lot of communication that used to be via email happening via IM I’ve been thinking about the differences between Email and IM.

I think it’s worth comparing them not for the purpose of convincing people to use one or the other (most people will use whatever is necessary to communicate with the people who are important to them) but for the purpose of considering ways to improve them and use them more effectively.

Also I don’t think that users of various electronic communications systems have had a free choice in what to use for at least 25 years and possibly much longer depending on how you define a free choice. What you use is determined by who you want to communicate with and by what systems are available in your region. So there’s no possibility of an analysis of this issue giving a result of “let’s all change what we use” as almost everyone lacks the ability to make a choice.

What the Difference is Not

The name Instant Messaging implies that it is fast, and probably faster than other options. This isn’t necessarily the case, when using a federated IM system such as Matrix or Jabber there can be delays while the servers communicate with each other.

Email used to be a slow communication method, in the times of UUCP and Fidonet email there could be multiple days of delay in sending email. In recent times it’s expected that email is quite fast, many web sites have options for authenticating an email address which have to be done within 5 minutes so the common expectation seems to be that all email is delivered to the end user in less than 5 minutes.

When an organisation has a mail server on site (which is a common configuration choice for a small company) the mail delivery can be faster than common IM implementations.

The Wikipedia page about Instant Messaging [1] links to the Wikipedia page about Real Time Computing [2] which is incorrect. Most IM systems are obviously designed for minimum average delays at best. For most software it’s not a bad thing to design for the highest performance on average and just let users exercise patience when they get an unusual corner case that takes much longer than expected.

If an IM message takes a few minutes to arrive then “that’s life on the Internet” – which was the catchphrase of an Australian Internet entrepreneur in the 90s that infuriated some of his customers.

Protocol and Data Format Differences

Data Formats

Email data contains the sender, one or more recipients, some other metadata (time, subject, etc), and the message body. The recipients are typically an arbitrary list of addresses which can only be validated by the destination mail servers. The sender addresses weren’t validated in any way and are now only minimally validated as part of anti-spam measures.

IM data is sent through predefined connections called rooms or channels. When an IM message is sent to a room it can tag one or more members of the room to indicate that they may receive a special notification of the message.

In many implementations it’s possible to tag a user who isn’t in the room which may result in them being invited to the room. But in IM there is no possibility to add a user to the CC list for part of a discussion and then just stop CCing messages to them later on in the discussion.

Protocols

Internet email is a well established system with an extensive user base. Adding new mandatory features to the protocols isn’t viable because many old systems won’t be updated any time soon. So while it is possible to send mail that’s SSL encrypted and has a variety of authentication mechanisms that isn’t something that can be mandatory for all email. Most mail servers are configured to use the SSL option if it’s available but send in cleartext otherwise, so a hostile party could launch a Man In the Middle (MITM) attack and pretend to be the mail server in question but without SSL support.

Modern IM protocols tend to be based on encryption, even XMPP (Jabber) which is quite an old IM protocol can easily be configured to only support encrypted messaging and it’s reasonable to expect that all other servers that will talk to you will at least support SSL. Even for an IM system that is run by a single company the fact that communication with the servers is encrypted by SSL makes it safer than most email. A security model of “this can only be read by you, me, and the staff at an American corporation” isn’t the worst type of Internet security.

The Internet mail infrastructure makes no attempt to send mail in order and the design of the Simple Mail Transfer Protocol (SMTP) means that a network problem after a message has been sent but before the recipient has confirmed receipt will mean that the message is duplicated and this is not considered to be a problem.

The IM protocols are designed to support reliable ordered transfer of messages and Matrix (the most recently designed IM protocol) has cryptographic connections between users.

Forgery

For most email systems there is no common implementation that prevents forging email. For Internet email transferred via SMTP it’s possible to use technologies like SPF and DKIM/DMARC to make recipients aware of attempts at forgery, but many recipient systems will still allow email that fails such checks to be delivered. The default configuration tends to be permitting everything and all of the measures to prevent forgery require extra configuration work and often trade-offs as some users desire features that go against security. The default configuration of most mail servers doesn’t even prevent trivial forgeries of email from the domain(s) owned by that server.

For evidence check the SPF records of some domains that you communicate with and see if they end with “-all” (to block email from bad sources), “~all” (to allow email from bad sources through after possibly logging an error), “?all” (to be “neutral” on mail from unknown sources, or just lack a SPF record entirely. The below shows that of the the top four mail servers in the world only outlook.com has a policy to reject mail from bad sources.

In most IM systems there is a strong connection between people who communicate. If I send you two direct messages they will appear in the same room, and if someone else tries forging messages from me (EG by replacing the ‘c’ and ‘e’ letters in my address with Cyrillic letters that look like them or by mis-spelling my name) a separate room will be created and it will be obvious that something unexpected is happening. Protecting against the same attacks in email requires the user carefully reading the message, given that it’s not uncommon for someone to start a message to me with “Hi Russel” (being unable to correctly copy my name from the To: field of the message they are writing) it’s obvious that any security measure relying on such careful reading will fail.

The IM protections against casual forgery also apply to rooms with multiple users, a new user can join a room for the purpose of spamming but they can’t send a casual message impersonating a member of the room. A user can join a Matrix room I’m in with the name “Russell” from another server but the potential for confusion will be minimised by a message notifying everyone that another Russell has joined the room and the list of users will show two Russells. For email the protections against forgery when sending to a list server are no different than those when sending to an individual directly – which means very weak protections.

Authenticating the conversation context once as done with IM is easier and more reliable than authenticating each message independently.

Is Email Sucking the Main Technical Difference?

It seems that the problems with forgery, spam, and general confusion when using email are a large part of the difference between email and IM.

But in terms of technical issues the fact that email has significantly more users (if only because you need an email account to sign up for an IM system) is a major difference.

Internet email is currently a universal system (apart from when it breaks from spam) and it has historically been used to gateway to other email systems like Fidonet, Uucp, and others. The lack of tight connection between parties that exchange messages in email makes it easier to bridge between protocols but harder to authenticate communication.

Most of the problems with Internet email are not problems for everyone at all times, they are technical trade-offs that work well for some situations and for some times. Unfortunately many of those trade-offs are for things that worked well 25+ years ago.

The GUI

From a user perspective there doesn’t have to be a great difference between email and IM. Email is usually delivered quickly enough to be in the same range as IM. The differences in layout between IM client software and email client software is cosmetic, someone could write an email client that organises messages in the same way as Slack or another popular IM system such that the less technical users wouldn’t necessarily know the difference.

The significant difference in the GUI for email and IM software was a design choice.

Conversation Organisation

The most significant difference in the operation of email and IM at the transport level is the establishment of connections in IM. Another difference is the fact that there are no standards implemented for the common IM implementations to interoperate which is an issue of big corporations creating IM systems and deliberately making them incompatible.

The methods for managing email need to be improved. Having an “inbox” that’s an unsorted mess of mail isn’t useful if you want to track one discussion, breaking it out into different sub folders for common senders (similar to IM folders for DMs) as a standard feature without having to setup rules for each sender would be nice. Someone could design an email program with multiple layouts, one being the traditional form (which seems to be copied from Eudora [3]) and one with the inbox (or other folders) split up into conversations. There are email clients that support managing email threads which can be handy in some situations but often isn’t the best option for quickly responding to messages that arrived recently.

Archiving

Most IM systems have no method for selectively archiving messages, there’s a request open for a bookmark function in Matrix and there’s nothing stopping a user from manually copying a message. But there’s nothing like the convenient ability to move email to an archive folder in most IM systems.

Without good archiving IM is a transient medium. This is OK for conversations but not good for determining the solutions to technical problems unless there is a Wiki or other result which can be used without relying on archives.

Composing Messages

In a modern email client when sending a message it prompts you for things that it considers complete, so if you don’t enter a Subject or have the word “attached” in the message body but no file is attached to the message then it will prompt you to confirm that you aren’t making a mistake. In an IM client the default is usually that pressing ENTER sends the message so every paragraph is a new message. IM clients are programmed to encourage lots of short messages while email clients are programmed to encourage more complete messages.

Social Issues

Quality

The way people think about IM and email is very different, as one example there was never a need for a site like nohello.net for email.

The idea that it’s acceptable to use even lower quality writing in IM than people tend to use in email seems to be a major difference between the communication systems.

It can be a good thing to have a chatty environment with messages that are regarded as transient for socialising, but that doesn’t seem ideal for business use.

Ownership

Email is generally regarded as being comparable to physical letters. It is illegal and widely considered to be socially wrong to steal a letter from someone’s letterbox if you regret sending it. In email the only unsend function I’m aware of is that in Microsoft software which is documented to only work within the same organisation, and that only works if the recipient hasn’t read the message. The message is considered to be owned by the recipient.

But for IM it’s a widely supported and socially acceptable function to delete or edit messages that have been sent. The message is regarded as permanently the property of the sender.

What Should We Do?

Community Creators

When creating a community (and I use this in the broadest sense including companies) you should consider what types of communication will work well.

When I started the Flounder group [4] I made a deliberate decision that non-free communication systems go against the aim of the group, I started it with a mailing list and then created a Matrix room which became very popular. Now the list hardly gets any use. It seems that most of the communication in the group is fairly informal and works better with IM.

Does it make sense to use both?

Should IM systems be supplemented with other systems that facilitate more detail such as a Wiki or a Lemmy room/instance [5] to cover the lack of long form communication? I have created a Lemmy room for Flounder but it hasn’t got much interest so far.

It seems that almost no-one makes a strategic decision about such issues.

Software Developers

It would be good to have the same options for archiving IM as there are for email. Also some options to encourage quality in IM communication similar to the way email clients want confirmation before sending messages without a subject or that might be missing an attachment.

It would also be good to have better options for managing conversations in email. The Inbox as currently used is good for some things but a button to switch between that and a conversation view would be good. There are email clients that allow selecting message sort order and aggregation (kmail has a good selection of options) but they are designed for choosing a single setup that you like not between multiple views based on the task you are doing.

It would be good to have links between different communication systems, if users had the option of putting their email address in their IM profile it would make things much easier. Having entirely separate systems for email and IM isn’t good for users.

Users

The overall communications infrastructure could be improved if more people made tactical decisions about where and how to communicate. Keep the long messages to email and the chatty things to IM. Also for IM just do the communication not start with “hello”. To discourage wasting time I generally don’t reply to messages that just say “hello” unless it’s the first ever IM from someone.

Conclusion

A large part of the inefficiencies in electronic communication are due to platforms and usage patterns evolving with little strategic thought. The only apparent strategic thought is coming from corporations that provide IM services and have customer lock in at the core of their strategies.

Free software developers have done great work in developing software to solve tactical problems but the strategies of large scale communications aren’t being addressed.

Email is loosely coupled and universal while IM is tightly coupled, authenticated, and often siloed. This makes email a good option for initial contact but a risk for ongoing discussions.

There is no great solution to these issues as they are largely a problem due to the installed user base. But I think we can mitigate things with some GUI design changes and strategic planning of communication.

Furilabs FLX1s

January 19, 2026 | etbe

The Aim

I have just got a Furilabs FLX1s [1] which is a phone running a modified version of Debian. I want to have a phone that runs all apps that I control and can observe and debug. Android is very good for what it does and there are security focused forks of Android which have a lot of potential, but for my use a Debian phone is what I want.

The FLX1s is not going to be my ideal phone, I am evaluating it for use as a daily-driver until a phone that meets my ideal criteria is built. In this post I aim to provide information to potential users about what it can do, how it does it, and how to get the basic functions working. I also evaluate how well it meets my usage criteria.

I am not anywhere near an average user. I don’t think an average user would ever even see one unless a more technical relative showed one to them. So while this phone could be used by an average user I am not evaluating it on that basis. But of course the features of the GUI that make a phone usable for an average user will allow a developer to rapidly get past the beginning stages and into more complex stuff.

Features

The Furilabs FLX1s [1] is a phone that is designed to run FuriOS which is a slightly modified version of Debian. The purpose of this is to run Debian instead of Android on a phone. It has switches to disable camera, phone communication, and microphone (similar to the Librem 5) but the one to disable phone communication doesn’t turn off Wifi, the only other phone I know of with such switches is the Purism Librem 5.

It has a 720*1600 display which is only slightly better than the 720*1440 display in the Librem 5 and PinePhone Pro. This doesn’t compare well to the OnePlus 6 from early 2018 with 2280*1080 or the Note9 from late 2018 with 2960*1440 – which are both phones that I’ve run Debian on. The current price is $US499 which isn’t that good when compared to the latest Google Pixel series, a Pixel 10 costs $US649 and has a 2424*1080 display and it also has 12G of RAM while the FLX1s only has 8G. Another annoying thing is how rounded the corners are, it seems that round corners that cut off the content are a standard practice nowadays, in my collection of phones the latest one I found with hard right angles on the display was a Huawei Mate 10 Pro which was released in 2017. The corners are rounder than the Note 9, this annoys me because the screen is not high resolution by today’s standards so losing the corners matters.

The default installation is Phosh (the GNOME shell for phones) and it is very well configured. Based on my experience with older phone users I think I could give a phone with this configuration to a relative in the 70+ age range who has minimal computer knowledge and they would be happy with it. Additionally I could set it up to allow ssh login and instead of going through the phone support thing of trying to describe every GUI setting to click on based on a web page describing menus for the version of Android they are running I could just ssh in and run diff on the .config directory to find out what they changed. Furilabs have done a very good job of setting up the default configuration, while Debian developers deserve a lot of credit for packaging the apps the Furilabs people have chosen a good set of default apps to install to get it going and appear to have made some noteworthy changes to some of them.

Droidian

The OS is based on Android drivers (using the same techniques as Droidian [2]) and the storage device has the huge number of partitions you expect from Android as well as a 110G Ext4 filesystem for the main OS.

The first issue with the Droidian approach of using an Android kernel and containers for user space code to deal with drivers is that it doesn’t work that well. There are 3 D state processes (uninterrupteable sleep – which usually means a kernel bug if the process remains in that state) after booting and doing nothing special. My tests running Droidian on the Note 9 also had D state processes, in this case they are D state kernel threads (I can’t remember if the Note 9 had regular processes or kernel threads stuck in D state). It is possible for a system to have full functionality in spite of some kernel threads in D state but generally it’s a symptom of things not working as well as you would hope.

The design of Droidian is inherently fragile. You use a kernel and user space code from Android and then use Debian for the rest. You can’t do everything the Android way (with the full OS updates etc) and you also can’t do everything the Debian way. The TOW Boot functionality in the PinePhone Pro is really handy for recovery [3], it allows the internal storage to be accessed as a USB mass storage device. The full Android setup with ADB has some OK options for recovery, but part Android and part Debian has less options. While it probably is technically possible to do the same things in regard to OS repair and reinstall the fact that it’s different from most other devices means that fixes can’t be done in the same way.

Applications

GUI

The system uses Phosh and Phoc, the GNOME system for handheld devices. It’s a very different UI from Android, I prefer Android but it is usable with Phosh.

IM

Chatty works well for Jabber (XMPP) in my tests. It supports Matrix which I didn’t test because I don’t desire the same program doing Matrix and Jabber and because Matrix is a heavy protocol which establishes new security keys for each login so I don’t want to keep logging in on new applications.

Chatty also does SMS but I couldn’t test that without the SIM caddy.

I use Nheko for Matrix which has worked very well for me on desktops and laptops running Debian.

Email

I am currently using Geary for email. It works reasonably well but is lacking proper management of folders, so I can’t just subscribe to the important email on my phone so that bandwidth isn’t wasted on less important email (there is a GNOME gitlab issue about this – see the Debian Wiki page about Mobile apps [4]).

Music

Music playing isn’t a noteworthy thing for a desktop or laptop, but a good music player is important for phone use. The Lollypop music player generally does everything you expect along with support for all the encoding formats including FLAC0 – a major limitation of most Android music players seems to be lack of support for some of the common encoding formats. Lollypop has it’s controls for pause/play and going forward and backward one track on the lock screen.

Maps

The installed map program is gnome-maps which works reasonably well. It gets directions via the Graphhopper API [5]. One thing we really need is a FOSS replacement for Graphhopper in GNOME Maps.

Delivery and Unboxing

I received my FLX1s on the 13th of Jan [1]. I had paid for it on the 16th of Oct but hadn’t received the email with the confirmation link so the order had been put on hold. But after I contacted support about that on the 5th of Jan they rapidly got it to me which was good. They also gave me a free case and screen protector to apologise, I don’t usually use screen protectors but in this case it might be useful as the edges of the case don’t even extend 0.5mm above the screen. So if it falls face down the case won’t help much.

When I got it there was an open space at the bottom where the caddy for SIMs is supposed to be. So I couldn’t immediately test VoLTE functionality. The contact form on their web site wasn’t working when I tried to report that and the email for support was bouncing.

Bluetooth

As a test of Bluetooth I connected it to my Nissan LEAF which worked well for playing music and I connected it to several Bluetooth headphones. My Thinkpad running Debian/Trixie doesn’t connect to the LEAF and to headphones which have worked on previous laptops running Debian and Ubuntu. A friend’s laptop running Debian/Trixie also wouldn’t connect to the LEAF so I suspect a bug in Trixie, I need to spend more time investigating this.

Wifi

Currently 5GHz wifi doesn’t work, this is a software bug that the Furilabs people are working on. 2.4GHz wifi works fine. I haven’t tested running a hotspot due to being unable to get 4G working as they haven’t yet shipped me the SIM caddy.

Docking

This phone doesn’t support DP Alt-mode or Thunderbolt docking so it can’t drive an external monitor. This is disappointing, Samsung phones and tablets have supported such things since long before USB-C was invented. Samsung DeX is quite handy for Android devices and that type feature is much more useful on a device running Debian than on an Android device.

Camera

The camera works reasonably well on the FLX1s. Until recently for the Librem 5 the camera didn’t work and the camera on my PinePhone Pro currently doesn’t work. Here are samples of the regular camera and the selfie camera on the FLX1s and the Note 9. I think this shows that the camera is pretty decent. The selfie looks better and the front camera is worse for the relatively close photo of a laptop screen – taking photos of computer screens is an important part of my work but I can probably work around that.

I wasn’t assessing this camera t find out if it’s great, just to find out if I have the sorts of problems I had before and it just worked. The Samsung Galaxy Note series of phones has always had decent specs including good cameras. Even though the Note 9 is old comparing to it is a respectable performance. The lighting was poor for all photos.

FLX1s

Note 9

Power Use

In 93 minutes having the PinePhone Pro, Librem 5, and FLX1s online with open ssh sessions from my workstation the PinePhone Pro went from 100% battery to 26%, the Librem 5 went from 95% to 69%, and the FLX1s went from 100% to 99%. The battery discharge rate of them was reported as 3.0W, 2.6W, and 0.39W respectively. Based on having a 16.7Wh battery 93 minutes of use should have been close to 4% battery use, but in any case all measurements make it clear that the FLX1s will have a much longer battery life. Including the measurement of just putting my fingers on the phones and feeling the temperature (FLX1s felt cool and the others felt hot).

The PinePhone Pro and the Librem 5 have an optional “Caffeine mode” which I enabled for this test, without that enabled the phone goes into a sleep state and disconnects from Wifi. So those phones would use much less power with caffeine mode enabled, but they also couldn’t get fast response to notifications etc. I found the option to enable a Caffeine mode switch on the FLX1s but the power use was reported as being the same both with and without it.

Charging

One problem I found with my phone is that in every case it takes 22 seconds to negotiate power. Even when using straight USB charging (no BC or PD) it doesn’t draw any current for 22 seconds. When I connect it it will stay at 5V and varying between 0W and 0.1W (current rounded off to zero) for 22 seconds or so and then start charging. After the 22 second display the phone will make the tick sound indicating that it’s charging and the power meter will measure that it’s drawing some current.

I added the table from my previous post about phone charging speed [6] with an extra row for the FLX1s. For charging from my PC USB ports the results were the worst ever, the port that does BC did not work at all it was looping trying to negotiate after a 22 second negotiation delay the port would turn off. The non-BC port gave only 2.4W which matches the 2.5W given by the spec for a “High-power device” which is what that port is designed to give. In a discussion on the Purism forum about the Librem5 charging speed one of their engineers told me that the reason why their phone would draw 2A from that port was because the cable was identifying itself as a USB-C port not a “High-power device” port. But for some reason out of the 7 phones I tested the FLX1s and the One Plus 6 are the only ones to limit themselves to what the port is apparently supposed to do. Also the One Plus 6 charges slowly on every power supply so I don’t know if it is obeying the spec or just sucking.

On a cheap AliExpress charger the FLX1s gets 5.9V and on a USB battery it gets 5.8V. Out of all 42 combinations of device and charger I tested these were the only ones to involve more than 5.1V but less than 9V. I welcome comments suggesting an explanation.

The case that I received has a hole for the USB-C connector that isn’t wide enough for the plastic surrounds on most of my USB-C cables (including the Dell dock). Also to make a connection requires a fairly deep insertion (deeper than the One Plus 6 or the Note 9). So without adjustment I have to take the case off to charge it. It’s no big deal to adjust the hole (I have done it with other cases) but it’s an annoyance.

Conclusion

The Furilabs support people are friendly and enthusiastic but my customer experience wasn’t ideal. It was good that they could quickly respond to my missing order status and the missing SIM caddy (which I still haven’t received but believe is in the mail) but it would be better if such things just didn’t happen.

The phone is quite user friendly and could be used by a novice.

I paid $US577 for the FLX1s which is $AU863 by today’s exchange rates. For comparison I could get a refurbished Pixel 9 Pro Fold for $891 from Kogan (the major Australian mail-order company for technology) or a refurbished Pixel 9 Pro XL for $842. The Pixel 9 series has security support until 2031 which is probably longer than you can expect a phone to be used without being broken. So a phone with a much higher resolution screen that’s only one generation behind the latest high end phones and is refurbished will cost less. For a brand new phone a Pixel 8 Pro which has security updates until 2030 costs $874 and a Pixel 9A which has security updates until 2032 costs $861.

Doing what the Furilabs people have done is not a small project. It’s a significant amount of work and the prices of their products need to cover that. I’m not saying that the prices are bad, just that economies of scale and the large quantity of older stock makes the older Google products quite good value for money. The new Pixel phones of the latest models are unreasonably expensive. The Pixel 10 is selling new from Google for $AU1,149 which I consider a ridiculous price that I would not pay given the market for used phones etc. If I had a choice of $1,149 or a “feature phone” I’d pay $1,149. But the FLX1s for $863 is a much better option for me. If all I had to choose from was a new Pixel 10 or a FLX1s for my parents I’d get them the FLX1s.

For a FOSS developer a FLX1s could be a mobile test and development system which could be lent to a relative when their main phone breaks and the replacement is on order. It seems to be fit for use as a commodity phone. Note that I give this review on the assumption that SMS and VoLTE will just work, I haven’t tested them yet.

The UI on the FLX1s is functional and easy enough for a new user while allowing an advanced user to do the things they desire. I prefer the Android style and the Plasma Mobile style is closer to Android than Phosh is, but changing it is something I can do later. Generally I think that the differences between UIs matter more when on a desktop environment that could be used for more complex tasks than on a phone which limits what can be done by the size of the screen.

I am comparing the FLX1s to Android phones on the basis of what technology is available. But most people who would consider buying this phone will compare it to the PinePhone Pro and the Librem 5 as they have similar uses. The FLX1s beats both those phones handily in terms of battery life and of having everything just work. But it has the most non free software of the three and the people who want the $2000 Librem 5 that’s entirely made in the US won’t want the FLX1s.

This isn’t the destination for Debian based phones, but it’s a good step on the way to it and I don’t think I’ll regret this purchase.

Terminal Emulator Security

January 11, 2026 | etbe

I just read this informative article on ANSI terminal security [1]. The author has written a tool named vt-houdini for testing for these issues [2]. They used to host an instance on their server but appear to have stopped it. When you run that tool you can ssh to the system in question and without needing a password you are connected and the server probes your terminal emulator for vulnerabilities. The versions of Kitty and Konsole in Debian/Trixie have just passed those tests on my system.

This will always be a potential security problem due to the purpose of a terminal emulator. A terminal emulator will often display untrusted data and often data which is known to come from hostile sources (EG logs of attempted attacks). So what could be done in this regard?

Memory Protection

Due to the complexity of terminal emulation there is the possibility of buffer overflows and other memory management issues that could be used to compromise the emulator.

The Fil-C compiler is an interesting project [3], it compiles existing C/C++ code with memory checks. It is reported to have no noticeable impact on the performance of the bash shell which sounds like a useful option to address some of these issues as shell security issues are connected to terminal security issues. The performance impact on a terminal emulator would be likely to be more noticeable. Also note that Fil-C compilation apparently requires compiling all libraries with it, this isn’t a problem for bash as the only libraries it uses nowadays are libtinfo and libc. The kitty terminal emulator doesn’t have many libraries but libpython is one of them, it’s an essential part of Kitty and it is a complex library to compile in a different way. Konsole has about 160 libraries and it isn’t plausible to recompile so many libraries at this time.

Choosing a terminal emulator that has a simpler design might help in this regard. Emulators that call libraries for 3D effects etc and native support for displaying in-line graphics have a much greater attack surface.

Access Control

A terminal emulator could be run in a container to prevent it from doing any damage if it is compromised. But the terminal emulator will have full control over the shell it runs and if the shell has access needed to allow commands like scp/rsync to do what is expected of them then that means that no useful level of containment is possible.

It would be possible to run a terminal emulator in a container for the purpose of connecting to an insecure or hostile system and not allow scp/rsync to/from any directory other than /tmp (or other directories to use for sharing files). You could run “exec ssh $SERVER” so the terminal emulator session ends when the ssh connection ends.

Conclusion

There aren’t good solutions to the problems of terminal emulation security. But testing every terminal emulator with vt-houdini and fuzzing the popular ones would be a good start.

Qubes level isolation will help things in some situations, but if you need to connect to a server with privileged access to read log files containing potentially hostile data (which is a common sysadmin use case) then there aren’t good options.

LEAF ZE1 After 6 Months

January 9, 2026 | etbe

About 6 months ago I got a Nissan LEAF ZE1 (2019 model) [1]. Generally it’s going well and I’m happy with most things about it.

One issue is that as there isn’t a lot of weight in the front with the batteries in the centre of the car the front wheels slip easily when accelerating. It’s a minor thing but a good reason for wanting AWD in an electric car.

When I got the car I got two charging devices, the one to charge from a regular 240V 10A power point (often referred to as a “granny charger”) and a cable with a special EV charging connector on each end. The cable with an EV connector on each end is designed for charging that’s faster than the “granny charger” but not as fast as the rapid chargers which have the cable connected to the supply so the cable temperature can be monitored and/or controlled. That cable can be used if you get a fast charger setup at your home (which I never plan to do) and apparently at some small hotels and other places with home-style EV charging. I’m considering just selling that cable on ebay as I don’t think I have any need to personally own a cable other than the “granny charger”.

The key fob for the LEAF has a battery installed, it’s either CR2032 or CR2025 – mine has CR2025. Some reports on the Internet suggest that you can stuff a CR2032 battery in anyway but that didn’t work for me as the thickness of the battery stopped some of the contacts from making a good connection. I think I could have got it going by putting some metal in between but the batteries aren’t expensive enough to make it worth the effort and risk. It would be nice if I could use batteries from my stockpile of CR2032 batteries that came from old PCs but I can afford to spend a few dollars on it.

My driveway is short and if I left the charger out it would be visible from the street and at risk of being stolen. I’m thinking of chaining the charger to a tree and having some sort of waterproof enclosure for it so I don’t have to go to the effort of taking it out of the boot every time I use it. Then I could also configure the car to only charge during the peak sunlight hours when the solar power my home feeds into the grid has a negative price (we have so much solar power that it’s causing grid problems).

The cruise control is a pain to use, so much so that I haven’t yet got it to work usefully ever. The features look good in the documentation but in practice it’s not as good as the Kia one I’ve used previously where I could just press one button to turn it on, another button to set the current speed as the cruise control speed, and then just have it work.

The electronic compass built in to the dash turned out to be surprisingly useful. I regret not gluing a compass to the dash of previous cars. One example is when I start google navigation for a journey and it says “go South on street X” and I need to know which direction is South so I don’t start in the wrong direction. Another example is when I know that I’m North of a major road that I need to take to get to my destination so I just need to go roughly South and that is enough to get me to a road I recognise.

In the past when there is a bird in the way I don’t do anything different, I keep driving at the same speed and rely on the bird to see me and move out of the way. Birds have faster reactions than humans and have evolved to move at the speeds cars travel on all roads other than freeways, also birds that are on roads are usually ones that have an eye in each side of their head so they can’t not see my car approaching. For decades this has worked, but recently a bird just stood on the road and got squashed. So I guess that I should honk when there’s birds on the road.

Generally everything about the car is fine and I’m happy to keep driving it.

Phone Charging Speeds With Debian/Trixie

January 5, 2026 | etbe

One of the problems I encountered with the PinePhone Pro (PPP) when I tried using it as a daily driver [1] was the charge speed, both slow charging and a bad ratio of charge speed to discharge speed. I also tried using a One Plus 6 (OP6) which had a better charge speed and battery life but I never got VoLTE to work [2] and VoLTE is a requirement for use in Australia and an increasing number of other countries. In my tests with the Librem 5 from Purism I had similar issues with charge speed [3].

What I want to do is get an acceptable ratio of charge time to use time for a free software phone. I don’t necessarily object to a phone that can’t last an 8 hour day on a charge, but I can’t use a phone that needs to be on charge for 4 hours during the day. For this part I’m testing the charge speed and will test the discharge speed when I have solved some issues with excessive CPU use.

I tested with a cheap USB power monitoring device that is inline between the power cable and the phone. The device has no method of export so I just watched it and when the numbers fluctuated I tried to estimate the average. I only give the results to two significant digits which is about all the accuracy that is available, as I copied the numbers separately the V*A might not exactly equal the W. I idly considered rounding off Voltages to the nearest Volt and current to the half amp but the way the PC USB ports have voltage drop at higher currents is interesting.

This post should be useful for people who want to try out FOSS phones but don’t want to buy the range of phones and chargers that I have bought.

Phones Tested

I have seen claims about improvements with charging speed on the Librem 5 with recent updates so I decided to compare a number of phones running Debian/Trixie as well as some Android phones. I’m comparing an old Samsung phone (which I tried running Droidian on but is now on Android) and a couple of Pixel phones with the three phones that I currently have running Debian for charging.

Chargers Tested

HP Z640

The Librem 5 had problems with charging on a port on the HP ML110 Gen9 I was using as a workstation. I have sold the ML110 and can’t repeat that exact test but I tested on the HP z640 that I use now. The z640 is a much better workstation (quieter and better support for audio and other desktop features) and is also sold as a workstation.

The z640 documentation says that of the front USB ports the top one can do “fast charge (up to 1.5A)” with “USB Battery Charging Specification 1.2”. The only phone that would draw 1.5A on that port was the Librem 5 but the computer would only supply 4.4V at that current which is poor. For every phone I tested the bottom port on the front (which apparently doesn’t have USB-BC or USB-PD) charged at least as fast as the top port and every phone other than the OP6 charged faster on the bottom port. The Librem 5 also had the fastest charge rate on the bottom port. So the rumours about the Librem 5 being updated to address the charge speed on PC ports seem to be correct.

The Wikipedia page about USB Hardware says that the only way to get more than 1.5A from a USB port while operating within specifications is via USB-PD so as USB 3.0 ports the bottom 3 ports should be limited to 5V at 0.9A for 4.5W. The Librem 5 takes 2.0A and the voltage drops to 4.6V so that gives 9.2W. This shows that the z640 doesn’t correctly limit power output and the Librem 5 will also take considerably more power than the specs allow. It would be really interesting to get a powerful PSU and see how much power a Librem 5 will take without negotiating USB-PD and it would also be interesting to see what happens when you short circuit a USB port in a HP z640. But I recommend not doing such tests on hardware you plan to keep using!

Of the phones I tested the only one that was within specifications on the bottom port of the z640 was the OP6. I think that is more about it just charging slowly in every test than conforming to specs.

Monitor

The next test target is my 5120*2160 Kogan monitor with a USB-C port [4]. This worked quite well and apart from being a few percent slower on the PPP it outperformed the PC ports for every device due to using USB-PD (the only way to get more than 5V) and due to just having a more powerful PSU that doesn’t have a voltage drop when more than 1A is drawn.

Ali Charger

The Ali Charger is a device that I bought from AliExpress is a 240W GaN charger supporting multiple USB-PD devices. I tested with the top USB-C port that can supply 100W to laptops.

The Librem 5 has charging going off repeatedly on the Ali charger and doesn’t charge properly. It’s also the only charger for which the Librem 5 requests a higher voltage than 5V, so it seems that the Librem 5 has some issues with USB-PD. It would be interesting to know why this problem happens, but I expect that a USB signal debugger is needed to find that out. On AliExpress USB 2.0 sniffers go for about $50 each and with a quick search I couldn’t see a USB 3.x or USB-C sniffer. So I’m not going to spend my own money on a sniffer, but if anyone in Melbourne Australia owns a sniffer and wants to visit me and try it out then let me know. I’ll also bring it to Everything Open 2026.

Generally the Ali charger was about the best charger from my collection apart from the case of the Librem 5.

Dell Dock

I got a number of free Dell WD15 (aka K17A) USB-C powered docks as they are obsolete. They have VGA ports among other connections and for the HDMI and DisplayPort ports it doesn’t support resolutions higher than FullHD if both ports are in use or 4K if a single port is in use. The resolutions aren’t directly relevant to the charging but it does indicate the age of the design.

The Dell dock seems to not support any voltages other than 5V for phones and 19V (20V requested) for laptops. Certainly not the 9V requested by the Pixel 7 Pro and Pixel 8 phones. I wonder if not supporting most fast charging speeds for phones was part of the reason why other people didn’t want those docks and I got some for free. I hope that the newer Dell docks support 9V, a phone running Samsung Dex will display 4K output on a Dell dock and can productively use a keyboard and mouse. Getting equivalent functionality to Dex working properly on Debian phones is something I’m interested in.

Battery

The “Battery” I tested with is a Chinese battery for charging phones and laptops, it’s allegedly capable of 67W USB-PD supply but so far all I’ve seen it supply is 20V 2.5A for my laptop. I bought the 67W battery just in case I need it for other laptops in future, the Thinkpad X1 Carbon I’m using now will charge from a 30W battery.

There seems to be an overall trend of the most shonky devices giving the best charging speeds. Dell and HP make quality gear although my tests show that some HP ports exceed specs. Kogan doesn’t make monitors, they just put their brand on something cheap. Buying one of the cheapest chargers from AliExpress and one of the cheaper batteries from China I don’t expect the highest quality and I am slightly relieved to have done enough tests with both of those that a fire now seems extremely unlikely. But it seems that the battery is one of the fastest charging devices I own and with the exception of the Librem 5 (which charges slowly on all ports and unreliably on several ports) the Ali charger is also one of the fastest ones. The Kogan monitor isn’t far behind.

Conclusion

Voltage and Age

The Samsung Galaxy Note 9 was released in 2018 as was the OP6. The PPP was first released in 2022 and the Librem 5 was first released in 2020, but I think they are both at a similar technology level to the Note 9 and OP6 as the companies that specialise in phones have a pipeline for bringing new features to market.

The Pixel phones are newer and support USB-PD voltage selection while the other phones either don’t support USB-PD or support it but only want 5V. Apart from the Librem 5 which wants a higher voltage but runs it at a low current and repeatedly disconnects.

Idle Power

One of the major problems I had in the past which prevented me from using a Debian phone as my daily driver is the ratio of idle power use to charging power. Now that the phones seem to charge faster if I can get the idle power use under control then it will be usable.

Currently the Librem 5 running Trixie is using 6% CPU time (24% of a core) while idle and the screen is off (but “Caffeine” mode is enabled so no deep sleep). On the PPP the CPU use varies from about 2% and 20% (12% to 120% of one core), this was mainly plasmashell and kwin_wayland. The OP6 has idle CPU use a bit under 1% CPU time which means a bit under 8% of one core.

The Librem 5 and PPP seem to have configuration issues with KDE Mobile and Pipewire that result in needless CPU use. With those issues addressed I might be able to make a Librem 5 or PPP a usable phone if I have a battery to charge it.

The OP6 is an interesting point of comparison as a Debian phone but is not a viable option as a daily driver due to problems with VoLTE and also some instability – it sometimes crashes or drops off Wifi.

The Librem 5 charges at 9.2W from a a PC that doesn’t obey specs and 10W from a battery. That’s a reasonable charge rate and the fact that it can request 12V (unsuccessfully) opens the possibility to potential higher charge rates in future. That could allow a reasonable ratio of charge time to use time.

The PPP has lower charging speeds then the Librem 5 but works more consistently as there was no charger I found that wouldn’t work well with it. This is useful for the common case of charging from a random device in the office. But the fact that the Librem 5 takes 10W from the battery while the PPP only takes 6.3W would be an issue if using the phone while charging.

Now I know the charge rates for different scenarios I can work on getting the phones to use significantly less power than that on average.

Specifics for a Usable Phone

The 57W battery or something equivalent is something I think I will always need to have around when using a PPP or Librem 5 as a daily driver.

The ability to charge fast while at a desk is also an important criteria. The charge speed of my home PC is good in that regard and the charge speed of my monitor is even better. Getting something equivalent at a desktop of an office I work in is a possibility.

Improving the Debian distribution for phones is necessary. That’s something I plan to work on although the code is complex and in many cases I’ll have to just file upstream bug reports.

I have also ordered a FuriLabs FLX1s [5] which I believe will be better in some ways. I will blog about it when it arrives.

Samsung 65″ QN900C 8K TV

December 22, 2025 | etbe

As a follow up from my last post about my 8K TV [1] I tested out a Samsung 65″ QN900C Neo QLED 8K that’s on sale in JB Hifi. According to the JB employee I spoke to they are running out the last 8K TVs and have no plans to get more.

In my testing of that 8K TV YouTube had a 3840*2160 viewport which is better than the 1920*1080 of my Hisense TV. When running a web browser the codeshack page reported it as 1920*1080 with a 1.25* pixel density (presumably a configuration option) that gave a usable resolution of 1536*749.

The JB Hifi employee wouldn’t let me connect my own device via HDMI but said that it would work at 8K. I said “so if I buy it I can return it if it doesn’t do 8K HDMI?” and then he looked up the specs and found that it would only do 4K input on HDMI. It seems that actual 8K resolution might work on a Samsung streaming device but that’s not very useful particularly as there probably isn’t much 8K content on any streaming service.

Basically that Samsung allegedly 8K TV only works at 4K at best.

It seems to be impossible to buy an 8K TV or monitor in Australia that will actually display 8K content. ASUS has a 6K 32″ monitor with 6016*3384 resolution for $2016 [2]. When counting for inflation $2016 wouldn’t be the most expensive monitor I’ve ever bought and hopefully prices will continue to drop.

Rumour has it that there are 8K TVs available in China that actually take 8K input. Getting one to Australia might not be easy but it’s something that I will investigate.

Also I’m trying to sell my allegedly 8K TV.
