One year ago I encountered a problem relevant to create a shortcut for relative path. I had to deliver a software package to customers over DVD. The app is kind of archive. It should run live on DVD, connect to a read-only SQLite database (also on that DVD) and display data in read-only mode. It’s pretty easy to deploy such software but when I copy files into a sub folder and create a shortcut to program on its parent folder. The shortcut won’t work on other machine because it uses absolute path and the icon won’t also appear. So a consideration raised if I should develop a Start.exe just to start the program or use some tricks to create a same thing.
Last month I ordered a Raspberry Pi for learning purpose. I heard a lot of about this mini computer and waited until its 2nd generation comes to market to get one. Depending on purposes, there are a lot of kits for Raspberry Pi in the market (from starter to professional). I myself don’t know what I can do with this mini computer therefore I just buy at least hardware first (listed in next section). Just enough so that Raspberry Pi runs and I can remote access it. So my first project is pretty simple : go shopping and make a remote access to Raspberry Pi with VNC (Virtual Network Computing). In this post I will write down the steps I’ve done to finish this mini project.
Years ago I wrote a small post about C# – OCR library candidates for comparing between OCR libraries of Tesseract and Microsoft Office Document Imaging. Tesseract is an open source OCR framework. Unfortunately, its inaccuracy is still high and can’t be used in commercial products. Last week I would like to make a small OCR web service for training myself and to test Tesseract again. The result is still as bad as last time (I guess FineReader of Abby may be the best OCR SDK but I have no full version for testing). Although Tesseract is not able to recognize complex documents, I also used it for this example because there is no other better candidate. The sample OCR web service works pretty simply, he receives a file which is uploaded from the client, runs OCR and returns text back. No big deal.
