基於 Go 語言構建高性能併發鍵值存儲
在分佈式系統和高併發場景中，鍵值存儲（Key-Value Store）作爲基礎組件扮演着至關重要的角色。本文將通過 Go 語言實現一個線程安全的併發鍵值存儲系統，深入探討其設計原理、性能優化策略以及實際應用場景。 爲什麼選擇 Go 語言？————Go 語言憑藉其原生的併發模型（goroutine 和 channel）、高效的內存管理以及簡潔的語法，成爲構建高性能併發系統的理想選擇。 ⌘ Read more

Go 併發設計的一個慣用法就是將帶緩衝 channel 用作計數信號量（counting semaphore）。帶緩衝 channel 中的當前數據個數代表的是當前同時處於活動狀態（處理業務）的 goroutine 的數量，而帶緩衝 channel 的容量（capacity）就代表了允許同時處於活動狀態的 goroutine 的最大數量。向帶緩衝 channel 的一個發送操作表示獲取一個信號量， ⌘ Read more

@lyse@lyse.isobeef.org The one in question is more like the javascript version for unwrapping errors when accessing methods.

 const value = some?.deeply?.nested?.object?.value

but for handling errors returned by methods. So if you wanted to chain a bunch of function calls together and if any error return immediately. It would be something like this:

b:= SomeAPIWithErrorsInAllCalls()
b.DoThing1() ?
b.DoThing2() ?

// Though its not in the threads I assume one could do like this to chain.
b.Chain1()?.Chain2()?.End()?

I am however infavor of having a sort of ternary ? in go.

@prologic@twtxt.net Which one? I don’t mind the ternary operator at all. In fact, I often find myself missing it in Go. I don’t find the two alternatives particularly elegant:

foo := "eggs"
if bar {
    foo = "spam"
}

Or:

var foo string
if bar {
    foo = "spam"
} else {
    foo = "eggs"
}

To my eye, this just would look a lot nicer:

foo := bar ? "spam" : "eggs"

Or at least as the Pythons do it:

foo = "spam" if bar else "eggs"

The ternary operator especially shines with relatively short expressions.

‘Has the world gone mad? It has’: foreign reporters share a view of Trump from abroad
Danielle Renwick,    -  The Guardian (U.K.)

_Stephan: The United States is now going down a well-traveled road, that path many other nations have recently taken as they cease to be genuine democracies and become electoral autocracies It may not be obvious to Americans and American media, but here is what it looks like to journalists from other nations that ha … ⌘ Read more

@prologic@twtxt.net @lyse@lyse.isobeef.org First, please leave me your comments on the repository! Even if it’s just to give your opinion on what shouldn’t be included. The more variety, the better.

Second, I’m going to try to do tests with Elliptic keys and base64. Thanks for the advice @eapl@eapl.me

Finally, I’d like to give my opinion. Secure direct messages are a feature that ActivityPub and Mastodon don’t have, to give an example. By including it as an extension, we’re already taking a significant leap forward from the competition. Does it make sense to include it in a public feed? In fact, we’re already doing that. When we reply to a user, mentioning them at the beginning of the message, it’s already a direct message. The message is within a thread, perhaps breaking the conversation. Direct messages would help isolate conversations between 2 users, as well as keeping a thread cleaner and maintaining privacy. I insist, it’s optional, it doesn’t break compatibility with any client and implementing it isn’t complex. If you don’t like it, you’re free to not use it. If you don’t have a public key, no one can send you direct messages.

While the US politicians and tech billionaires are going full-on fascist mode, here is a reminder that there are European alternatives for many well known digital and online services: https://european-alternatives.eu

New memo shows ‘exactly how Republicans plan to sell out the American people’: senator
Matthew Chapman,  Staff Writer  -  Raw Story

_Stephan: I think that within the next month, starting with this coming Tuesday, we are going to see just how radically felon Trump and his MAGAts plan to restructure American society. If felon Trump does what he says he wants to do by June you and I will not recognize the United States we have known all our liv … ⌘ Read more

US to hit debt ceiling Tuesday, starting Congress’ countdown clock
Tami Luhby,  Senior Writer  -  CNN

Stephan: This isn’t what everyone is talking about today but starting tomorrow we will see this and newly inaugurated Trump’s executive orders sweep across the United States like a hurricane. Buckle up it is going to get strange and, I am afraid, very chaotic.

Real Estate Vultures Eye Middle-Class Enclave of Ravaged LA
Michelle Ma, Jennifer Epstein and Kelsey Butler ,  Staff Writers  -  msn | Bloomberg

_Stephan: Even as the fires still rage, the real estate profit vultures have descended on the burned-out neighborhoods of Los Angeles. We are far far from the end of this story. And, I predict, it is going to play out all over the nation as climate change wreaks havoc. To his credit, California’s Democratic Governor Gavin … ⌘ Read more

U.S. Political Parties Historically Polarized Ideologically
Megan Brenan,    -  The Gallup Organization

_Stephan: I have been telling you for years about what I call The Great Schism Trend. As this report from Gallup confirms this trend is real, and the split is growing ever greater. We are increasingly becoming two countries in a single nation. I think we will stay one nation, but I also think real power is going to move to the states, and they are going to become … ⌘ Read more

Patient Care Deteriorates After Private Equity Acquisition of Hospitals

Oligarchs already own much of U.S. – can they buy democracy?
,    -  Agence France-Presse (France) / Raw Story

Stephan: Can the oligarchs buy control of the United States? They already control many of the levers of power, corporations, media, and influence in government. I think we are going to get our answer in the first 100 days of criminal Trump’s presidency.

Go os-exec 極速入門
os/exec 是 Go 提供的內置包，可以用來執行外部命令或程序。比如，我們的主機上安裝了 redis-server 二進制文件，那麼就可以使用 os/exec 在 Go 程序中啓動 redis-server 提供服務。當然，我們也可以使用 os/exec 執行 ls、pwd 等操作系統內置命令。本文不求內容多麼深入，旨在帶大家極速入門 os/exec 的常規使用。極速入門如下是 os/exec ⌘ Read more

Young, single men are leaving traditional churches. They found a more ‘masculine’ alternative
Susie Coen,  U.S. Correspondent  -  The Telegraph (U.K.)

_Stephan: We have what I see as a serious negative cultural trend going on in the United States. Young single, mostly White, men don’t seem to understand what the role of manhood is about. They are frightened and resentful about gender equality. This is strongly reflected in what is happ … ⌘ Read more

I have no idea what happened in/around instagram but, Holly Shi_ !! People have been pouring out of it and into #Pixelfed for hours now. 😆 way to go #Fedi

Alright, I have a little 8086 assembler for my toy OS going now – or rather a proof-of-concept thereof. It only supports a tiny fraction of the instruction set. It was an interesting learning experience, but I don’t think trying to “complete” this program is worth my time.

The whole thing is just a learning project, I don’t want to actually make a usable OS. There are a few more things I want to have a look at and then I’ll eventually move on to 386/amd64 later this year (hopefully).

Go 併發機制解密：Goroutine 調度
Goroutine 是 Go 編程語言中一個極具特色的設計，也是其併發能力的核心亮點之一。Goroutine 本質上是一種協程（Coroutine），是實現並行計算的關鍵。使用 Goroutine 非常簡單，只需通過 go 關鍵字即可啓動一個協程，協程會以異步方式運行。程序無需等待 Goroutine 完成即可繼續執行後續代碼。go func() // 使用 go 關鍵字啓動一個協程 II. Go ⌘ Read more

** Styrofoam cups and awk **
I like writing these posts for my website, but I’ve sat down to write this one like 11 times and it either takes on a tone of totally encompassing dread and dystopian navel gazing or I feel like I’m burying my head in the sand and ignoring reality as it happens around me.
