@nprofile…85mj Both apps had no problem maintaining their respective connections. Messages were delivered instantly (as indicated by double check marks + me hearing the notification when I happened to be in the same room as the test phone)

2024-11-26 11:29:14

I installed #Signal and #Conversations_im on a clean install of #GrapheneOS on my Pixel 4a and measured the battery impact. The results are shocking!
Both messengers had only one contact: my regular phone.
I used my regular phone to send messages to the Pixel 4a (which was not used for anything else over the course of the experiment).
I always sent the same message via Signal and #XMPP (mixing up which app went first). In total I sent ~32 messages in intervals of 10mins to a few hours.

Good news and bad news.
#Conversations_im 2.17.0 has support for emoji reactions 🎉
Since @npub1kzk…k9tq appears to be under constant DDoS attacks they have added pretty strict rate limits that the @npub1z2j…r69f build server keeps running into. 😞
Another build cycle just failed and it's unclear when 2.17.0 will be available on F-Droid.
Maybe Codeberg and F-Droid can back channel an allow list or something? 🙏

After 15+ years of using tiling window managers (mostly #i3) I find myself tempted by some of the aspects a proper desktop environment like #GNOME Shell provides. (The toolbar with quick access to power and connectivity settings and the native support for function keys including nice looking screen overlays.)
However there is absolutely no way I’m going to give up automatic tiling.
Has anyone successfully made the switch from i3 to one of the Gnome Shell extensions? (gTile, forge, PaperVM, …)

@npub150h…zw04 there is no straight forward way to do this. But your specific device should be excluded from call integration in version 2.15.2

2024-04-18 07:32:25

Are you running #Conversations_im on an Realme or OnePlus devices with stock ROM? Are calls still working for you on version 2.14.2 and above?
Not working would likely manifest itself as a dialog that says "Call not sent" or the operating system opening the default calling app instead of the Conversations UI. Incoming calls would likely be rejected as busy immediately. (There may or may not be other symptoms.)
Please let me know either way and tell me your Android version.

Conversations 2.15 reorganizes the settings into different categories. This gets rid of the old 'Expert Settings' which hid a lot of useful settings.
One nice setting that was previously hidden away in the expert setting is 'Direct Search'. This gives you direct access to the search field in the 'New Chat' screen. If you want to start a new chat with someone you only have to type enough characters to make the search result unique and then press enter.

I was about to start a poll asking if #Conversations_im should add a fallback STUN server (stun.conversations.im) for the ~40% of #XMPP servers that don’t offer one via XEP-0215 External Service Discovery.
And then the network of our hosting provider went out for ~5 minutes acting as a good reminder of why the app doesn’t on centralized infrastructure…

When in doubt take a look what terminology the 'Messages' (default SMS / RCS) app uses.

2024-04-05 06:59:41

A quick note to our translators:
First of all thank you for your work!
#Conversations_im 2.15.0 will change the terminology from 'conversation' to 'chat' and from 'close' to 'archive'.
Chat is shorter and feels like a more commonly used word in that context. It avoids some potentially confusing situations in which it's not immediately clear if the app is referring to itself or to to multiple chats.
In your translations use what ever you feel works best in your language!

I tried arguing with Google for a while however their 7 day deadline to admit publicly that I'm uploading the contact list is running out tomorrow so to not risk the app being removed again I was forced to publish a version without address book integration.
It seems like you can only have an app that requests contacts permission on the PlayStore if you boldly declare that you upload them.

2024-03-12 18:39:47

Google had accepted a version of Conversations with address book integration that explicitly asks the user for consent to process the contact list locally on their device before promoting for contacts permission. Our privacy policy included explicit wording w.r.t. local processing of the contact list.
However it is unthinkable for Google that someone would request contacts permission and then *not* upload them. A few days later they changed their mind and threatened to remove the app again.

Unpopular opinion on "minimum target SDK" (Re: This week in F-Droid¹)
The target SDK is often framed as a draconian requirement that poses unnecessary restrictions upon app developers. However they often improve security. For example target SDK 24 disallows sharing file URIs. If the developer of a chat app could rely on all apps that share files (Galleries, File Managers) targeting >23 it would be easier to prevent security issues like the one just fixed in Element.

One of the arguments Meta/WhatsApp have made in favor of opening up their client to server API instead of true server-to-server federation is the ability to fight spam.
While this argument may or may not have been made in bad faith (I’m sure c2s also gives them more opportunities to track users, sell ads and stay in control) it is true that federated protocols have a massive spam problem. We see this right now in XMPP, ActivityPub¹ and (obviously) E-Mail!

@npub14kt…vcm8 Debugging what is very likely network issues over Mastodon is virtually impossible.
What I can tell you is that the provider in question relies on the DNS server in your network to be able to properly resolve SRV records. This unfortunately isn’t always the case.
What you can try is to enable 'Extended connection settings' in the 'Expert settings' of Conversations and then specify the hostname, im.aria-net.site, in your case, manually in the account details.

2024-02-15 15:54:12

@npub14kt…vcm8 'refuses to connect' is extremely generic. What error message are you getting?

2024-02-15 05:48:35

To celebrate Conversations being back on the Play Store and to deny Google their 15% cut I made the app free for the next ~48 hours. 😜
If you are new here: Check out #XMPP. It's federated, provider and vendor independent instant messaging. It’s great!
https://play.google.com/store/apps/details?id=eu.siacs.conversations
Or get it from #fdroid - That version even has address book integration and public channel discovery! 😂

2024-02-14 18:13:31

In related news the update for Quicksy.im went through a few hours ago as well. (The Conversations fork that does actually upload your contact list didn’t get removed but Google rejected all updates I tried to push over the last month or so.)
Thanks to @npub1qkq…ltaz for the hint to place more links to the privacy policy in all sorts of places around the app. (The links were there before; but apparently not enough of them)

2024-02-14 18:05:13

I hastily threw together a version of #Conversations_im that has no address book integration and doesn’t ask for Contacts permission.
This seems to have made it through Google Play review just now meaning the app is no available on Google Play again.
No indication from Google that they were in the wrong and hallucinated the whole "uploads contact list" thing. Instead I had to walk the path of least resistance and remove the useful and entirely harmless feature of address book integration.

2024-02-14 16:10:10

Let’s not forget that #Conversations_im was a paid app in Google Play. I made Google tens of thousands of Dollars in revenue over the years. You would think that this somehow entitled me to speak to a human for half an hour but you'd be wrong.

2024-02-14 14:38:05

Since people are asking how the can help with the situation.
· It’s a long shot but consider up-voting the Hacker News post: https://news.ycombinator.com/item?id=39368233 (I’m mostly just saying this to point out the absurdity of the situation that the only possible way to talk to an actual human at Evil Corp is to get enough traction on Hacker News.)
· I’m definitely not trying to solicit donations. I really like how Play Store sales shifted the financing away from "hardcore fans" to regular / more casual users.

2024-02-14 11:49:07

Appealing the removal didn’t yield any result. Google just repeated the same statement "the app was removed because it uploads the contact list" without even acknowledging any of the arguments I made in the appeal.
I understand that most of my audience here on Mastodon is more ideology aligned with F-Droid but the app sales on Google Play store have contributed significantly to me working (almost) full time on #Conversations_im.
Without the revenue from Google Play I can’t afford this.

2024-02-14 09:15:31

Google has just removed #Conversations_im from the Play Store because they think we are uploading the user’s contact list. We don’t.

@npub1qkq…ltaz Yes it's linked from the app but thus far I have been focused on the wording around the consent screens not the placement of the link. I'll give it another shot putting the link in more obvious places. Guess we'll know in 3-4 days...

@npub1htm…5ul7 I guess people are registering but then not sticking around. Stagnating user count doesn’t necessarily means it's the same group users over the years. Plus re-registrations of users uninstalling+installing again.

2024-02-13 09:48:43

Here is some important context you need to understand Quicksy:
· It’s not successful at all. The user count has stagnated at just under 1,500 for years.
· It’s very expensive to run. While Quicksy doesn’t have that many users it has a good amount of registrations. Sending SMS is really expensive. There are months in which I’m paying ~100 Euro for server cost + SMS. I receive a few donations that reference Quicksy alongside Conversations but nothing close to 100 Euro / month.

2024-02-13 09:38:37

Google Play is refusing to let me update Quicksy. Apparently the "APK has a privacy policy but it is not adequate". I went through several iterations in the last couple of weeks trying to reword the disclosure on how Quicksy handles user data (especially the contact list) . Nothing seems good enough for Google. They are not letting me know what specifically isn’t "adequate" about my privacy policy. Each attempt to fix the situation takes ~3 days to receive feedback.
I can’t do this anymore.

Despite the testing I’m currently doing on Android 6 & 7 Conversations 2.14.0 will bump the minimum Android version from 5 to 6. (API 21 to API 23)
However a 2.13.1, which brings improved P2P file transfer, will be released later today (pending PlayStore review).

Quick update on the "I’m looking for old Android phones to test Conversations" situation (A little delayed because I had a very enjoyable winter holiday followed by the XMPP Summit and FOSDEM).
Thanks for the many offers and the boosts to increase visibility! Two phones, a Nexus 5 (Android 6) and a Galaxy S6 (Android 7), made their way to me. Special thanks to those two people.
Preliminary testing looks good. Expect the improved call integration to be merged soon!

2024-01-16 16:33:54

Does anyone have a working Android 6 or Android 7 device in a drawer somewhere that they want to donate to the #Conversations_im project? (Anything higher or lower doesn’t work unfortunately)
While refactoring A/V calls I got myself into a situation where I can no longer verify that calls are working on these devices without access to a physical devices. (Emulator has knows issues when it comes to A/V calls.)
The oldest device I have access to *shipped* with Android 8 (and runs Lineage OS 17)

2024-01-16 09:04:27

The reason I’m thinking about #XMPP<->Telephone Network is that I’m currently reworking how Conversations A/V calls integrate into the operating system and I’m one small step away from being able to tell Android "hey I can route normal phone calls for you"; However if one proprietary provider is virtually the only sensible way to do this I’m not interested. Given users the ability to easily self host is very important to the design philosophy of #Conversations_im.

2024-01-16 07:40:49

Is there any XMPP<->Telephony Network transport other than JMP/Soprani.ca that allows me to make calls with Conversations (or any other modern Jingle #XMPP client)
Soprani.ca seems like a pretty convoluted stack to set up if one wanted to self host.
TBH I don’t even know enough about the problem space to formulate what I’m looking for.
I think I already have a SIP account (comes with my internet at home / but never used it) so I guess I’m just looking for a 'modern Jingle'<->SIP gateway?

As it is a long, long tradition Conversations is available for free on the Google Play store for the last week of December.
This tradition was originally born so that when I meet people at Chaos Communication Congress and they ask what I do, they have an easy way to install Conversations. In that regard it's a very special year as we are seeing the return of CCC.
However if you are meeting loved ones to celebrate something else these days that’s fine too.🎄

Let’s give Meta the benefit of the doubt for one second and assume they want to embrace and extend but not extinguish #ActivityPub. Where do they go for the extend part? XMPP has the XMPP Standards Foundation that gives a diverse set of stakeholders a framework to collaborate on new extensions.
From standing on the sidelines for a year it looks a lot like #Mastodon is pretty much just doing their own thing.

2023-12-20 08:21:39

Intellectually I realize that Google Talk using XMPP was a big deal but personally I never experienced it like that. In the late aughts, during the peak of Google Talk, I had ~1 contact on it. My other contacts were all using regular Jabber servers.
You can stay here. Nobody forces you to migrate to #Threads. And if 1 or 2 interesting people are on Threads and I can follow them from here that’s good, no?

Sorry for the expired certificates on share.conversations.im (the HTTP Upload domain we use on conversations.im)
My personal certificate setup has pretty much always been that I get certificates via DNS challenge on my local machine and upload them to the XMPP server (and to my website etc).
Last month I set this in stone via CAA records but completely forgot that share.conversations.im is it's own machine. Looked for an hour today on the wrong host trying to find the expired cert.

2023-12-19 16:42:59

I just finished a refactor of the Jingle File Transfer code in #Conversations_im.
The P2P file transfer code was probably one of the oldest code in Conversations.
The new code should be a lot more resilient and brings support for XEP-0343: Signaling WebRTC datachannels in Jingle¹. This means we should be able to exchange files directly with #XMPP web clients.
Due to the better NAT hole punching of WebRTC vs Socks Bytestreams we now have a higher chance of actual P2P.

@npub188w…eqpn @npub1qml…mdus I have never measured or even experienced the battery impact of Signal w/o GCM so I don’t want to make any public claims about Conversations being more efficient. If however what you just said is true my assumption would be that working without vendor push (APNS/GCM) is absolutely not a priority for them. On iOS (which has vastly more market share in the US) it's a non starter anyway. They are not stupid they just don’t care and never tried to optimize it in the first place

@npub188w…eqpn to be clear I’m not saying that Conversations’ method is more efficient. It's just that @npub1qml…mdus speaks of their own method as 'destroying the user’s battery' while I know for a fact the implementation in Conversations is not.
My assumption is rather that they vastly exaggerate the battery impact of their own implementation to make GCM seem like something they absolutely have to use.
Signals battery impact might be completely acceptable and Conversations’ only very marginally better

Version 0.4.0 (Codename „All Engines Running“) of Ltt.rs not only brings support for #UnifiedPush but also a UI refresh. The e-mail client for Android now supports Material U / dynamic colors.
#autocrypt #opensource #email
Note that Ltt.rs requires an e-mail server that supports #JMAP. (There aren’t many providers that support it so Ltt.rs is currently more for the adventurous / self hosting type user.)

@npub1fmd…vcx3 I agree that Conversations should have had an iOS client in 2017/2018 during the peak of its popularity.
I don’t understand how this relates to @npub1qml…mdus being extremely cagey on if and how one can map Signal IDs to Google Accounts and spreading FUD about services that don’t use FCM instantly destroying your battery.

I didn’t realize that @npub1ue3…kryc had their own #fdroid repository¹ for a while. Now - through the magic of reproducible builds - Threema Libre is even available in the official @npub1z2j…r69f repository.
That’s pretty cool! I like it when developers work with the open source instead of having nothing but despite for the »FOSS libertarian dream«².

@npub13dc…5aw9 @npub1ynl…873s my earlier criticism (see https://gultsch.social/@daniel/111565910462764838 ) went entirely unnoticed. So yes tone is important 😉

@npub1eec…xp4f disclaimer I'm well aware that measuring battery impact is hard but according to Androids own battery stats the one picture I took today had a more significant battery impact than Conversations had running in background. So did listing to podcasts for a few minutes.

@npub1eec…xp4f You are 100% correct.
In practice the impact of a well implemented, persistent TCP connection is insignificant compared to other things that drain your battery like screen time etc. At least insignificant enough that I consider talking about "destroying your battery" as framing.
I also believe that not every app developer should have to go through the process of "implementing it well" - so push definitively has it's place. But it is also not without alternatives.

@npub1ynl…873s ideology maybe. Lack of understanding probably not. I’ve been working in the instant messaging industry for 10 years now.

If @npub1qml…mdus wanted to they could easily build support for #UnifiedPush and let the professionals (Conversations in that case) maintain the persistent TCP if their implementation would otherwise (and that's their wording) destroy the users battery.

@npub1d73…0w5x I have my own PeerTube instance over at @npub1953…zu2j and was planning to upload it there.
That doesn’t mean you aren’t allowed to mirror it though.

Do I have to give another talk on how push notifications work? With @npub1ynl…873s of @npub1qml…mdus spreading lies and news outlets like @npub185n…luq0 amplifying their nonsense I feel like their is a lot of confusion out there on how push works. Google’s push notifications aren’t delivered by fairy dust and don’t consume any battery.
TLDR: You can de-google your phone. Install Conversations. It is the only app running in background. It will use #UnifiedPush to wake up other apps like Tusky and Ltt.rs.

Had a good 1.5 days in Berlin.
Met up with @npub176s…9ezp to work on Jingle File Transfer.
Gave a talk at the Berlin XMPP Meetup about the recent attack on jabber.ru.
Thank you for having me.
(The talk was recorded. Not yet processed and I gave it in German. Sorry international audience 😕)

@npub1ynl…873s if your persistent TCP connection drains the phone's battery I think you might have implemented it wrong. How do you think Google Push works under the hood?

2023-12-07 09:54:59

Only a minority of Conversations users (maybe 20-25%, extrapolated from crash reports) use the Google Play version and thus use Firebase Cloud Messaging (and only if their server supports it too)

Can somebody with some fingerprinting skills confirm that they are running @npub1ahl…9p9c on xmpp.ayoba.me?

2023-11-12 10:24:14

Someone pointed me to Ayoba.me last night. They claim to have 25M monthly active users¹ and are using #XMPP. They have an XMPP server running on xmpp.ayoba.me and addresses are in the sha1(e164)@ayoba.me format.
When you decompile the APK it appears as if the app was originally based on the GPLv3 licensed Kontalk.net (which uses the same address format).
The XMPP server has client certificate login enabled (which also matches what Kontalk is doing).

Why does nobody who works for Google understand that forcing indie app developers to publish their home address is a really fucking stupid idea?
This will literally get people killed.
Are they doing this on purpose?

@npub1m29…khl9 Federation rarely works (for example I never see replies to something that has been boosted)
Mastodon closed access to the streaming API which means that service like fedi.buzz have a much harder time.

2023-11-06 18:04:46

If federation is an afterthought at best and in some cases something you are actively trying to prevent (I’m looking at you #Mastodon 4.2.0) why is it called The Fediverse?

In case you were wondering why #Conversations_im permanently stores DNS results beyond their TTL: There are enough shitty airport and hotel wifi networks that refuse to resolve anything but A (and maybe AAAA) records. 🤷

If you have a minute can you help me do one final round of testing? #Conversations_im 2.12.12-beta.3 is out on F-Droid and the Google Play beta channel.
To test DNS properly you have to set up a second account (It doesn’t have to have valid credentials; running into 'Unauthorized' is enough to validate DNS).
I forgot to mention this last time but Conversations does cache the last successful address it was able to connect to as a last resort endpoint. (Caching is per account)

2023-10-25 13:35:41

For Conversations 2.12.12 I refactored how DNS resolution works including adding support for "Private DNS" (That’s what Android calls DNS over TLS). Obviously DNS is vital to Conversations functioning correctly.
Please help us test this - especially, but not just - if you connect through a VPN and/or are using Private DNS! 🙏
Conversations 2.12.12-beta.2 is now available on F-Droid (if you allow Beta updates) and on the Google Play Store Beta Channel.

Automattic, the company that owns wordpress.com just bought, what can best be described as a Pidgin.im knockoff, for $50 million.

We should thank German authorities for reminding us of the importance of CAA records. I've set mine up today (and tested them).

@npub1e68…4xlf Dein Körper hat aber leider (zum Glück?) nur eine metabolic efficiency von ~21%¹ das heißt für jedes Joule was in den Pedalen ankommt muss der Körper 4-5 verbrennen.
Mein Problem ist eher das ich bei 200 Watt nicht mehr in der fat burning zone bin 😂

@npub1jvd…nl3q for now this seems to be limited to new accounts.
To me this is a class issue. Rich people will just rent an office somewhere and use that address instead of their home address.
