@movq@www.uninformativ.de Yeah, most of the graphical applications are actually KDE programs:

• KMail – e-mail client
  
• Okular – PDF viewer
  
• Gwenview – image viewer
  
• Dolphin – file browser
  
• KWallet – password manager (I want to check out pass one day. The most annoying thing is that when I copy a password, it says that the password has been modified and asks me whether I want to save the changes. I never do, because the password is still the same. I don’t get it.)
  
• KPatience – card game
  
• Kdenlive – video editor
  
• Kleopatra – certificate manager
  

Qt:

• VLC – video player
  
• Psi – Jabber client (I happily used Kopete in the past, but that is not supported anymore or so. I don’t remember.)
  
• sqlitebrowser – SQLite browser
  

Gtk:

• Firefox – web browser
  
• Quod Libet – music player (I should look for a better alternative. Can’t remember why I had to move away from Amarok, was it dead? There was a fork Clementine or so, but I had to drop that for some unknown reason, too.)
  
• Audacity – audio editor
  
• GIMP – image editor
  

These are the things that are open right now or that I could think of. Most other stuff I actually do in the terminal.

In the past™, I used the Python KDE4 bindings. That was really nice. I could pass most stuff directly in the constructor and didn’t have to call gazillions of setters improving the experience significantly. If I ever wanted to do GUI programming again, I’d definitely go that route. There are also great Qt bindings for Python if one wanted to avoid the KDE stuff on top. The vast majority I do for myself, though, is either CLI or maybe TUI. A few web shit things, but no GUIs anymore. :-)

@movq@www.uninformativ.de Where can I join your club? Although, most software I use is decentish in that regard.

There Are Four Things You Must Do to Save America

Thanks, @xuu@txt.sour.is, great explanation. In another project I’ve structured it exactly like you wrote. The mock storage over there extends the SQLite storage and provides mechanism to return errors and such for testing purposes:

• storage/ defines the interface
  
  • sqlite/ implements the storage interface
    
  • mock/ extends the SQLite implementation by some mocking capabilities and assertions
    

Here, however, there are no storage subpackages. It’s just storage, that’s it. Everything is in there. The only implementation so far is an SQLite backend that resides in storage. My RAM storage is exactly that SQLite storage, but with :memory: instead a backing file on disk. I do not have a mock storage (yet).

I have to think about it a bit more, but I probably have to do exactly that in my tt rewrite, too. Sigh. I just have the feeling that in storage/sqlite/sqlite_test.go I cannot import storage/mock for the helper because storage/mock/mock.go imports and embeds the type from storage/sqlite. But I’m too tired right now to think clearly.

@lyse@lyse.isobeef.org OK. So how I have worked things like this out is to have the interface in the root package from the implementations. The interface doesn’t need to be tested since it’s just a contract. The implementations don’t need to import storage.Storage

• storage/ defines the Storage interface (no tests!)
  
  • storage/sqlite for the sqlite implementation tests for sqlite directly
    
  • storage/ram for the ram implementation and tests for RAM directly
    
• controller/ can now import both storage and the implementation as needed.
  

So now I am guessing you wanted the RAM test for testing queries against sqlite and have it return some query response?

For that I usually would register a driver for SQL that emulates sqlite. Then it’s just a matter of passing the connection string to open the registered driver on setup.

@xuu@txt.sour.is My layout looks like this:

• storage/
  
  • storage.go: defines a Storage interface
    
  • sqlite.go: implements the Storage interface
    
  • sqlite_test.go: originally had a function to set up a test storage to test the SQLite storage implementation itself: newRAMStorage(testing.T, $initialData) *Storage
    
• controller/
  
  • feeds.go: uses a Storage
    
  • feeds_test.go: here I wanted to reuse the newRAMStorage(…) function
    

I then tried to relocate the newRAMStorage(…) into a

• teststorage/
  
  • storage.go: moved here as NewRAMStorage(…)
    

so that I could just reuse it from both

• storage/
  
  • sqlite_test.go: uses testutils.NewRAMStorage(…)
    
• controller/
  
  • feeds_test.go: uses testutils.NewRamStorage(…)
    

But that results into an import cycle, because the teststorage package imports storage for storage.Storage and the storage package imports testutils for testutils.NewRAMStorage(…) in its test. I’m just screwed. For now, I duplicated it as newRAMStorage(…) in controller/feeds_test.go.

I could put NewRAMStorage(…) in storage/testutils.go, which could be guarded with //go:build testutils. With go test -tags testutils …, in storage/sqlite_test.go could just use NewRAMStorage(…) directly and similarly in controller/feeds_test.go I could call storage.NewRamStorage(…). But I don’t know if I would consider this really elegant.

The more I think about it, the more appealing it sounds. Because I could then also use other test-related stuff across packages without introducing other dedicated test packages. Build some assertions, converters, types etc. directly into the same package, maybe even make them methods of types.

If I went that route, I might do the opposite with the build tag and make it something like !prod instead of testing. Only when building the final binary, I would have to specify the tag to exclude all the non-prod stuff. Hmmm.

Poll on Trump’s 2025 joint address to Congress finds large majority of viewers approve
Anthony Salvanto,  Reporter  -  CBS News

Stephan: The fundamental source of the problems with America is Republican frightened, resentful, ignorant Americans. They are the ones who elected this monster, and they are also the ones who are going to be most severely impacted by his greed, corruption, and madness.

yaegi：讓你的 Go 代碼擁有動態腳本能力
在 Go 語言的世界裏，靜態編譯是其一大特色，能夠保證性能和安全性。然而，有些場景下，我們希望像 Python 或 JavaScript 一樣，支持運行時動態執行代碼，比如插件化架構、規則引擎、腳本解釋器等。今天，我們來介紹一個強大的 Go 解釋器庫——yaegi，它能讓 Go 代碼在運行時執行動態腳本。yaegi 簡介yaegi 是一個用 Go 語言編寫的 Go 解釋器。它可以在運行時解析和執行 ⌘ Read more

Tariff War Risks Sinking World Into New Great Depression, International Chamber of Commerce Warns
Joshua Kirby,  Economic Reporter  -  The Wall Street Journal

Analysis Finds Trump Tariffs Will Cost Average US Family $1,600 or More Per Year
Jessica Corbett,  Senior Editor  -  Common Dreams

Maybe $1,600 this year is not that much to you, but to millions of U.S. families it is going to have a serious impact. And after the State of the U … ⌘ Read more

Go Context 實踐指南：以生產環境問題爲例

Trump Reveals Tariffs Plan to Ruin American Farmers’ Lives
Malcolm Ferguson,  Associate writer  -  The New Republic

Stephan: Thanks to the stupidity of “king” Trump, who clearly does not understand what tariffs are, Americans, like you and me, are about to see a number of farmers go broke, and the prices we pay for produce at the grocery go up by as much as 25%

在 Go 中如何使用分佈式鎖解決併發問題？
在分佈式系統中，協調多個服務實例之間的共享資源訪問是一個經典的挑戰。傳統的單機鎖（如 sync.Mutex）無法實現跨進程工作，此時就需要用到分佈式鎖了。本文將介紹 Go 語言生態中基於 Redis 實現的分佈式鎖庫 redsync，並探討其使用方法和實現原理。分佈式鎖首先我們來探討下爲什麼需要分佈式鎖？當我們編寫的程序出現資源競爭的時候，就需要使用互斥鎖來保證併發安全。而我們的服務很有可能不會單 ⌘ Read more

Local and State Police are Joining Trump’s Deportation Force
Francesca D’Annunzio,  David McHam Investigative Reporting Fellow  -  Texas Observer

_Stephan: Here is the fact-based truth about what is going on with deportation. Two things stand out for me. The first is that the Trump coup is actually deporting fewer people than Biden’s presidency did. The second is that Trump is now basically militarizing local and state police exactly as Hitler did.
