揭祕 Go sync-Map 設計與實現
什麼是 sync.Map————我們都知道在 Go 語言中，普通的 Map 是非併發安全，併發讀寫時會 panic，sync.Map 則是官方庫提供的一種特殊的併發安全的映射類型，能保較高的性能的同時，還能保證併發安全。sync.Map 有以下幾個特點：sync.Map 特點併發安全： sync.Map 無需額外的鎖機制即可在多個 goroutine 中安全地進行讀寫操作。這對於高 ⌘ Read more

Go 語言實現高性能文本壓縮算法 Brotli
在信息爆炸的時代，數據如同洪流般湧現，如何高效地存儲和傳輸這些數據成爲了一項至關重要的技術挑戰。壓縮技術應運而生，它如同一位技藝精湛的魔術師，能夠將龐大的數據文件 “化繁爲簡”，在不損失信息或損失極少信息的情況下將其壓縮成更小的體積，從而節省存儲空間、提高傳輸效率。壓縮技術主要分爲兩大類：無損壓縮和有損壓縮。無損壓縮：顧名思義，這種壓縮方式能夠在解壓縮後完全恢復原始數據，不會造成任何信息損失。常見 ⌘ Read more

I share I did write up an algorithm for it at some point I think it is lost in a git comment someplace. I’ll put together a pseudo/go code this week.

Super simple:

Making a reply:

1. If yarn has one use that. (Maybe do collision check?)
   
2. Make hash of twt raw no truncation.
   
3. Check local cache for shortest without collision
   
   • in SQL: select len(subject) where head_full_hash like subject || '%'
     

Threading:

1. Get full hash of head twt
   
2. Search for twts
   
   • in SQL: head_full_hash like subject || '%' and created_on > head_timestamp
     

The assumption being replies will be for the most recent head. If replying to an older one it will use a longer hash.

@prologic@twtxt.net I wanted to wait for things to settle down. It’s still unclear to me in which direction we’re going – and if that new/different stuff is even possible to implement in jenny. That said, I’ve been really busy with private stuff these last few days, I’ve lost track of most of what you’re discussing. 🥴

If we stuck with Blake2b for Twt Hash(es); what do we think we need to reasonably go to in bit length/size?

=> https://gist.mills.io/prologic/194993e7db04498fa0e8d00a528f7be6

e.g: (turns out @xuu@txt.sour.is is right about Blak2b being easy/simple too!):

$ printf "%s\t%s\t%s" "https://example.com/twtxt.txt" "2024-09-29T13:30:00Z" "Hello World!" | b2sum -l 32 -t | awk '{ print $1 }'
7b8b79dd

@prologic@twtxt.net Regarding the new way of generating twt-hashes, to me it makes more sense to use tabs as separator instead of spaces, since the you can just copy/past a line directly from a twtxt-file that already go a tab between timestamp and message. But tabs might be hard to “type” when you are in a terminal, since it will activate autocomplete…🤔

Another thing, it seems that you sugget we only use the domain in the hash-creation and not the full path to the twtxt.txt

Starting a couple of new projects (geez where do I find the time?!):

HomeTunnel:

HomeTunnel is a self-hosted solution that combines secure tunneling, proxying, and automation to create your own private cloud. Utilizing Wireguard for VPN, Caddy for reverse proxying, and Traefik for service routing, HomeTunnel allows you to securely expose your home network services (such as Gitea, Poste.io, etc.) to the Internet. With seamless automation and on-demand TLS, HomeTunnel gives you the power to manage your own cloud-like environment with the control and privacy of self-hosting.

CraneOps:

craneops is an open-source operator framework, written in Go, that allows self-hosters to automate the deployment and management of infrastructure and applications. Inspired by Kubernetes operators, CraneOps uses declarative YAML Custom Resource Definitions (CRDs) to manage Docker Swarm deployments on Proxmox VE clusters.

And finally the legibility of feeds when viewing them in their raw form are worsened as you go from a Twt Subject of (#abcdefg12345) to something like (https://twtxt.net/user/prologic/twtxt.txt 2024-09-22T07:51:16Z).

There is also a ~5x increase cost in memory utilization for any implementations or implementors that use or wish to use in-memory storage (yarnd does for example) and equally a 5x increase in on-disk storage as well. This is based on the Twt Hash going from a 13 bytes (content-addressing) to 63 bytes (on average for location-based addressing). There is roughly a ~20-150% increase in the size of individual feeds as well that needs to be taken into consideration (on the average case).

So really your argument is just that switching to a location-based addressing “just makes sense”. Why? Without concrete pros/cons of each approach this isn’t really a strong argument I’m afraid. In fact I probably need to just sit down and detail the properties of both approaches and the pros/cons of both.

I also don’t really buy the argument of simplicity either personally, because I don’t technically see it much more difficult to take a echo -e "<url>\t<timestamp>\t<content>" | sha256sum | base64 as the Twt Subject or concatenating the <url> <timestamp> – The “effort” is the same. If we’re going to argue that SHA256 or cryptographic hashes are “too complicated” then I’m not really sure how to support that argument.

I wrote some code to try out non-hash reply subjects formatted as (replyto ), while keeping the ability to use the existing hash style.

I don’t think we need to decide all at once. If clients add support for a new method then people can use it if they like. The downside of course is that this costs developer time, so I decided to invest a few hours of my own time into a proof of concept.

With apologies to @movq@www.uninformativ.de for corrupting jenny’s beautiful code. I don’t write this expecting you to incorporate the patch, because it does complicate things and might not be a direction you want to go in. But if you like any part of this approach feel free to use bits of it; I release the patch under jenny’s current LICENCE.

Supporting both kinds of reply in jenny was complicated because each email can only have one Message-Id, and because it’s possible the target twt will not be seen until after the twt referencing it. The following patch uses an sqlite database to keep track of known (url, timestamp) pairs, as well as a separate table of (url, timestamp) pairs that haven’t been seen yet but are wanted. When one of those “wanted” twts is finally seen, the mail file gets rewritten to include the appropriate In-Reply-To header.

Patch based on jenny commit 73a5ea81.

https://www.falsifian.org/a/oDtr/patch0.txt

Not implemented:

• Composing twts using the (replyto …) format.
  
• Probably other important things I’m forgetting.

隨着大型語言模型（LLM）及其相關工具（如嵌入模型）在過去一年中能力顯著提升，越來越多的開發者考慮將 LLM 集成到他們的應用程序中。由於 LLM 通常需要專用硬件和大量計算資源，它們通常作爲網絡服務打包，提供 API 供訪問。這就是 OpenAI 和 Google Gemini 等領先 LLM 的 API 工作方式；即使是像 Ollama 這樣的自託管 LLM 工具，也將 LLM 封裝在 RES ⌘ Read more

Golang 使用 upx 減少可執行文件的大小
衆所周知，Golang 的編譯速度是非常之快的。在設計 Go 時，編譯速度是一個重要的考慮因素。但是，你是否關注過 Go 編譯代碼後生成的二進制可執行文件的大小？讓我們來看一個簡單的 HTTP 服務的應用示例：import (       ”fmt”       ”net/http” )   func main() {       // create a http server and creat ⌘ Read more

I have configured my twtxt.txt as simple as possible. I have setup a publish_command on jenny. Hopefully all works fine, and I am good to go. Next will be setting the announce_me to true. Here we go!

@movq@www.uninformativ.de going a little sideways on this, “*If twtxt/Yarn was to grow bigger, then this would become a concern again. But even Mastodon allows editing, so how much of a problem can it really be? 😅*”, wouldn’t it preparing for a potential (even if very, very, veeeeery remote) growth be a good thing? Mastodon signs all messages, keeps a history of edits, and it doesn’t break threads. It isn’t a problem there.😉 It is here.

I think keeping hashes is a must. If anything for that “feels good” feeling.

Hey, @movq@www.uninformativ.de, a tiny thing to add to jenny, a -v switch. That way when you twtxt “That’s an older format that was used before jenny version v23.04”, I can go and run jenny -v, and “duh!” myself on the way to a git pull. :-D

Regarding jenny development: There have been enough changes in the last few weeks, imo. I want to let things settle for a while (potential bugfixes aside) and then I’m going to cut a new release.

And I guess the release after that is going to include all the threading/hashing stuff – if we can decide on one of the proposals. 😂

@prologic@twtxt.net the real conclusion is, is it going to change, to what, and when? :-P

Go 語言實現 systemctl 管理系統服務
在 Linux 系統中，systemd 已然成爲主流的初始化系統和服務管理器，而 systemctl 命令則是我們與之交互的橋樑。對於 Go 開發者而言，直接使用 Shell 調用 systemctl 固然可行，但難免顯得不夠優雅，並且需要編寫額外的代碼來解析命令輸出。爲解決這一問題，taigrr/systemctl 庫應運而生。它爲 Go 開發者提供了符合習慣用法的 systemctl  綁定， ⌘ Read more

@lyse@lyse.isobeef.org fully agree. I have never been a fan of relative times to begin with, so that one will go away, foh sho! :-D

yarnd just doesn’t render the subject. Fair enough. It’s (replyto http://darch.dk/twtxt.txt 2024-09-15T12:50:17Z), and if you don’t want to go on a hunt, the twt hash is weadxga: https://twtxt.net/twt/weadxga

@aelaraji@aelaraji.com this is my change on main.go (but it can be done on a template now, so no reason to touch the code):

                                 <time class="dt-published" datetime="{{ $twt.Created | date "2006-01-02T15:04:05Z07:00" }}">
                                        {{ $twt.Created | date "2006-01-02 15:04:05 MST" }}
                                  </time>

See https://ferengi.one. I am going to further customise things, but that’s a start.

@lyse@lyse.isobeef.org Sorry, I don’t think I ever had charset=utf8. I just noticed that a few days ago. OpenBSD’s httpd might not support including a parameter with the mime type, unfortunately. I’m going to look into it.

Now WTF!? Suddenly, @falsifian@www.falsifian.org’s feed renders broken in my tt Python implementation. Exactly what I had with my Go rewrite. I haven’t touched the Python stuff in ages, though. Also, tt and tt2 do not share any data at all.

By any chance, did you remove the ; charset=utf-8 from your Content-Type: text/plain header, falsifian?

Image

@movq@www.uninformativ.de Non-ASCII characters were broken. Like U+2028, degrees (°), etc.

Turns out I used a silly library to detect the encoding and transform to UTF-8 if needed. When there is no Content-Type header, like for local files, it looks at the first 1024 bytes. Since it only saw ASCII in that region, the damn thing assumed the data to be in Windows-1252 (which for web pages kinda makes sense):

// TODO: change default depending on user's locale?
return charmap.Windows1252, "windows-1252", false

https://cs.opensource.google/go/x/net/+/master:html/charset/charset.go;l=102

This default is hardcoded and cannot be changed.

Trying to be smart and adding automatic support for other encodings turned out to be a bad move on my end. At least I can reduce my dependency list again. :-)

I now just reject everything that explicitly specifies something different than text/plain and an optional charset other than utf-8 (ignoring casing). Otherwise I assume it’s in UTF-8 (just like the twtxt file format specification mandates) and hope for the best.

Hmmmm, I somehow run into an encoding problem where my inserted data end up mangled in the database. But, both SQLite and Go use UTF-8. What’s happening here? :-?

@movq@www.uninformativ.de I did the same. jenny fetches archives, yes, but that twtxt I am referring about is no longer. If you fetch it, but I don’t, there is certainly something going on…

@movq@www.uninformativ.de I figured it will be something like this, yet, you were able to reply just fine, and I wasn’t. Looking at your twtxt.txt I see this line:

2024-09-16T17:37:14+00:00	(#o6dsrga) @<prologic https://twtxt.net/user/prologic/twtxt.txt>

@<quark https://ferengi.one/twtxt.txt> This is what I get. 🤔

Which is using the right hash. Mine, on the other hand, when I replied to the original, old style message (Message-Id: <o6dsrga>), looks like this:

2024-09-16T16:42:27+00:00	(#o) @<prologic https://twtxt.net/user/prologic/twtxt.txt> this was your first twtxt. Cool! :-P

What did you do to make yours work? I simply went to the oldest @prologic@twtxt.net’s entry on my Maildir, and replied to it (jenny set the reply-to hash to #o, even though the Message-Id is o6dsrga). Since jenny can’t fetch archived twtxts, how could I go to re-fetch everything? And, most importantly, would re-fetching fix the Message-Id:?

@prologic@twtxt.net I am going to light some candles this weekend to “La Virgen de Macarena” to make it happen! :-D
