最近遇上太多「號稱背後是OpenAI」的大型語言模型API，但實際上並不是「OpenAI的API」的狀況。這種誤解造成實際開發時帶來很大的困擾，我們藉這個機會說明一下吧。

PDF檔案的安全性加密與解除限制通常需要特別的軟體。如果我們只有手機的話，不妨來使用我開發的Colab PDF Protector，用Google Colab的腳本新增或移除PDF的安全性設定吧。
PDF file security encryption and decryption often require specialized software. If you only have a mobile phone, consider using my Colab PDF Protector, a Google Colab script designed to add or remove security settings from PDFs.

最近幫別人改寫老舊Excel上的VBA，讓使用者能直接從輸入資料到彙整成可以列印的格式，而避免大量的複製、貼上操作。寫是寫完了，但內心真是五味雜陳。

PDF的註解功能可以允許我們在原始檔案上添增額外的文字、標亮、線條、筆記。而且這些註解還可以刪除、修改，讓原始檔案保持它原本的樣子。不過如果有大量註解需要移除的話，手動操作其實非常繁瑣。這時候你可以用我開發的PDF Annotation Remover，讓PDF檔案的註解全部移除吧。
PDF's annotation feature allows us to add additional text, highlights, lines, and notes directly onto the original file. These annotations can also be deleted or modified, preserving the original document's integrity. However, manually removing a large number of annotations can be quite tedious. For this, you can use my PDF Annotation Remover to remove all annotations from your PDF file.

由於我會在越來越地方使用Stable Diffusion繪圖，所以我花了一些時間用AppSheet做了提示詞管理工具。這篇就來聊一下我做了那些東西。

列印、簽名、拍照、轉換成PDF、上傳，這是現在很多證明文件的處理手續。處理後的PDF檔案只是圖片的封裝，不能直接選取與複製，只能作為證明文件留存，這已經是最基本的資安防護手段。然而，如果可以將數位文件直接轉換成彷彿掃描檔一樣的檔案，那不就可以省下列印與掃描的繁雜手續了嗎？也許這時候Docker APP ScanSim PDF就能夠派上用場了。
Printing, signing, taking a photo, converting it to PDF, and uploading it—this is the procedure for processing many verification documents nowadays. The processed PDF file is merely a container for the image; the text cannot be directly selected or copied. It can only serve as an archive of the verification document, which is a basic security measure. However, if digital documents could be directly converted into files that resemble scanned documents, wouldn't that eliminate the tedious printing and scanning steps? Perhaps the Docker APP ScanSim PDF could be useful in this situation.

畢竟是免費的AI功能，真的不能要求太多。

隨著在Dify使用的知識庫越來越多，傳統的用相似度來計算權重分數的做法已經不敷使用，而使用重排序模型來排序檢索結果順序的做法也越來越受歡迎。這次我們來架設HuggingFace推出的Text Embeddings Inference，並讓Dify能用它來做重排序吧。
As the knowledge base used in Dify grows, the traditional method of calculating weight scores based on similarity is becoming inadequate. Using reranking models to reorder retrieval results is gaining popularity. Let's set up HuggingFace's Text Embeddings Inference and integrate it into Dify for reranking.

如果你覺得用Zotero引用資料時，欄位的值不太正確，那通常都是轉譯器的問題。我們可以試著去修改轉譯器，然後在Zotero Connector裡按下「Reset Translators」按鈕讓修改後的轉譯器生效。
If you find that the field values are incorrect when citing materials using Zotero, it's usually a translator issue. We can try modifying the translator and then click the "Reset Translators" button in the Zotero Connector to apply the changes.

有段時間桌寵概念挺流行的。大家都想要在桌面養個什麼玩意兒來分散自己寶貴的注意力。後來我也決定在工作列裝個CatWalk，看小貓配合我努力工作時狂奔。

CITATION.cff是用於記錄供人引用資訊的一種YAML純文字格式。那要怎麼知道自己寫的CITATION.cff是否正確呢？我們可以用R套件cffr來驗證。我在Colab把它寫成了可以線上使用的CITATION.cff驗證工具了，讓我們一起來看看怎麼使用吧。
CITATION.cff is a plain text YAML format for recording citation information. How can you tell if your CITATION.cff is correct? We can use the R package cffr for validation. I've created an online CITATION.cff validator using Colab. Let's take a look at how to use it.
