During the last few weeks I've been working on QtWinForms, a cross-platform reimplementation of System.Windows.Forms running on QtWidgets github.com/alnkesq/QtWi... #dotnet #winforms

Now you can connect AppViewLite to a Nitter instance and follow Twitter profiles directly from AppViewLite. #atproto #appview

AppViewLite changelog: - Populate external previews when composing a post - "Mute this thread" - Drastically reduce synchronous waits on slice compactations - Upgraded to .NET 10

Now AppViewLite automatically detects when performance is degraded by overly full probabilistic sets, and recommends configuration changes.

AppViewLite changelog: - Hide this reply - Reduced memory consumption / GC - Set language when posting - Fixed muting of Reddit users - Fixed ARM support - Profiler: show network requests - Fix occasional crashes when scrolling Following - Preserve page location when switching profiles

Added some initial Docker container support to AppViewLite

Now /debug/requests/<guid> includes a simple profiler to see which operations take the longest to complete or perform the most IO.

Open sourcing a simple scripting tool that I use to automatically configure my machines (Linux or Windows). Can run incrementally after you make changes to the configuration script.

Now you can log in to multiple accounts in AppViewLite, and quickly switch between them using the sidebar.

it's interesting how well appviewlite's balanced following feed makes me 1. not actively hate scrolling here 2. see posts from people that i'd easily miss in the usual chronological view really decent logic there

Now samples of your saved feeds are shown in the Following feed. I also fixed a performance problem with cold starts of the following feed

I took a long dev break during the last 2 months, so here are some recent updates: - Populate {Like,Repost}.via, to notify the reposter of your like - Fix IO performance regression that was introduced with caching - Sidebar announcement when disk space is running low - Support for Telegram videos

AppViewLite tip: if you navigate to <HOST>/r/somesubreddit, it will redirect you to the corresponding AppViewLite page for that subreddit's RSS (which you can then follow)

Apparently, Firefox automatically displays a notification dot on pinned tabs, if the page title is set to "(X) Page title" where X is a number. I discovered this by accident by seeing it on AppViewLite despite not having written any custom code to change the favicon

The AppViewLite default timeline tries to fairly distribute your feed's vertical space among the profiles you follow, even if they post at very different frequencies

Now you can speed up the video playback rate in AppViewLite

New pluggable protocol: now you can follow GitHub projects from AppViewLite (issues, releases, PRs, or issues)

I have a 10 year old machine that I bought for $80 with full network data since February (when I started working on appviewlite). It replaced most of my usage of bsky.social

Can social-app be live-reloaded after making some typescript code changes? Otherwise launching "yarn web" takes 2 minutes

If you attempt to quote or repost a non-ATProto post (Tumblr in this case), AppViewLite will use html2canvas to render it to an image and post it as a BlueSky-readable post (prepopulating the alt text with the original text)

Now you can set a nickname for a list / labeler, which will be displayed in lieu of the original name, on post and profile badges.

The PLC directory used to grow 20-30 MB / day. Now with all this spam it's 500 MB / day. alsoKnownAs[] is stuffed with very long gibberish strings

Firehose listeners: does reconnection *with cursor* work for you? I tried various jetstream firehoses, and once the consumer catches up to real time, the connection is abruptly dropped by the server #atproto

Now AppViewLite can attach images to posts.

If you hold SHIFT while opening a profile menu, AppViewLite will show you block and list related pages for that profile

2 months of full firehose data

Now you can spread the AppViewLite database files across multiple volumes (for example, by moving large historical slices to slow rotating drives while keeping everything else on fast solid storage)

You can't know the size of a CAR before downloading it, and processing its records requires random access. So AppViewLite will stream the CAR, keep the records and paths in memory, and after a certain threshold it will write the CBOR of new records to disk, keeping track of the offsets in memory.

Implemented tons of perf improvements and fixes recently - Primary / readonly replica (within the same process), with versioning - Probabilistic sets for quick membership/follow/block lookup - Separate threadpool for firehose indexing and web serving - Direct IO with sector-sized reads

Now AppViewLite uses a mix of O_DIRECT reads and memory mapped files. Previously it used only the former, but this meant that reads unlikely to be reused in the future risk evicting more useful pages

I added charts about the processing of the firehose in AppViewLite

Repository backfill UI: you can import CAR repositories, or just individual collections (com.atproto.repo.listRecords).

Added pruning support. You can for example keep everything more recent than 1 month, and old stuff only if involves your extended social graph neighborhood

Now you can configure labeler settings. You can also subscribe to lists as if they were labelers (badge), without muting them altogether.

Dark theme and custom accent colors

Now AppViewLite lets you export your data, including your images and videos (something that bsky.app doesn't provide yet)

I added support for bookmarks (private likes), and for following non-ATProto profiles (Nostr, Fediverse, RSS...)

Now the media tab is displayed as a media grid

Now AppViewLite supports the Fediverse and Nostr as well (in read only mode)

Someone once told me that "no one wants highly technical talks at this tech conference" so I quietly named my next talk "highly technical talk." It was #1 talk and #3 talk in engagement viewership and minutes watched. I hope my point was made 😁

Today's changes to AppViewLite: - JK keyboard navigation - Image viewer - Emojis are correctly indexed - Display a dot on the Scroll up button when the current feed has new items - Use separate Read/Write locks for better parallelism

Today's changes to AppViewLite: - Image proxying from the PDS (and optional caching) - Configurable DID doc overrides, with the ability to listen to relays and PDSes not included in the default bsky.network relay.

- Handles are now displayed and validated (DNS/.well-known) - Badges based on Wikidata "official website" and "bluesky handle" properties - Bulk import of the PLC directory from parquet - Show popular feeds - Profile search autocomplete - Honor blocks, threadgates, and postgates

I did something similar in AppViewLite. Blocks, quote removals, and threadgates simply blur posts, and you can see the detailed reason. The focal post is always visible (unless there's a block between you and the author)

- Added feed and profile search - Bottom nav bar on mobile - Scroll up button Feed search also shows you the underlying feed implementation (BlueFeed, SkyFeed...)

I was also inadvertently wasting storage space because not all structs had [StructLayout(Pack = 1)], so alignment and padding created extra empty space. Now I added a check to avoid that in the future. github.com/alnkesq/AppV... #csharp #dotnet

Added feed search support to AppViewLite, and also list browsing (including reverse list lookup, like on ClearSky). Because why not.

Now posts are loaded dynamically using SignalR, in case they weren't originally captured from the firehose, such as in the case of old likes and reposts. Profile pages now include descriptions, follow/unfollow buttons, and social proof

Implemented today: - Follow and unfollow - Quote posting - Post deletions - Live post stats (like on twitter)
