            NHibernate doesn't delete orphans in one-to-many relationship
            Asked 2021-Jun-14 at 15:43

            While deleting and adding works fine, when I update the Parent collection of child entities, the foreign keys on child records are simply set to null. I'd like them to be completely removed from the database.

            So I've been trying Cascade.All, Cascade.DeleteOrphans, Cascade.All.Include(Cascade.DeleteOrphans) and nothing seems to work.

            If I set Inverse to true on the parent but it causes the child records to not get updated at all.

            This would be a perfect instance of when to use an annotation. You could define the annotation before the declaration of each class, indicating that the class has some meta-data about 'DALObjects'. Then you could use Reflections or some similar library to easily find all Class objects with this annotation.

            Looking at the analysisInfo map, the field names do not match the instance variable name in your POJO. For instance, the field name is fullPullChannelCount whereas your map has fullpullchannelcount.

            Use @JsonProperty to map the property name in the map to the variable in the POJO.

            differences in bitmap or rasterized font bitmaps and text display on 3.5" TFT LCD
            Asked 2021-Jun-12 at 16:19

            I am using a 3.5: TFT LCD display with an Arduino Uno and the library from the manufacturer, the KeDei TFT library. The library came with a bitmap font table that is huge for the small amount of memory of an Arduino Uno so I've been looking for alternatives.

            What I am running into is that there doesn't seem to be a standard representation and some of the bitmap font tables I've found work fine and others display as strange doodles and marks or they display upside down or they display with letters flipped. After writing a simple application to display some of the characters, I finally realized that different bitmaps use different character orientations.

            My question

            What are the rules or standards or expected representations for the bit data for bitmap fonts? Why do there seem to be several different text character orientations used with bitmap fonts?

            Thoughts about the question

            Are these due to different target devices such as a Windows display driver or a Linux display driver versus a bare metal Arduino TFT LCD display driver?

            What is the criteria used to determine a particular bitmap font representation as a series of unsigned char values? Are different types of raster devices such as a TFT LCD display and its controller have a different sequence of bits when drawing on the display surface by setting pixel colors?

            What other possible bitmap font representations requiring a transformation which my version of the library currently doesn't offer, are there?

            Is there some method other than the approach I'm using to determine what transformation is needed? I currently plug the bitmap font table into a test program and print out a set of characters to see how it looks and then fine tune the transformation by testing with the Arduino and the TFT LCD screen.

            My experience thus far

            The KeDei TFT library came with an a bitmap font table that was defined as

            Raster or bitmap fonts are represented in a number of different ways and there are bitmap font file standards that have been developed for both Linux and Windows. However raw data representation of bitmap fonts in programming language source code seems to vary depending on:

            • the memory architecture of the target computer,
            • the architecture and communication pathways to the display controller,
            • character glyph height and width in pixels and
            • the amount of memory for bitmap storage and what measures are taken to make that as small as possible.

            A brief overview of bitmap fonts

            A generic bitmap is a block of data in which individual bits are used to indicate a state of either on or off. One use of a bitmap is to store image data. Character glyphs can be created and stored as a collection of images, one for each character in the character set, so using a bitmap to encode and store each character image is a natural fit.

            Bitmap fonts are bitmaps used to indicate how to display or print characters by turning on or off pixels or printing or not printing dots on a page. See Wikipedia Bitmap fonts

            A bitmap font is one that stores each glyph as an array of pixels (that is, a bitmap). It is less commonly known as a raster font or a pixel font. Bitmap fonts are simply collections of raster images of glyphs. For each variant of the font, there is a complete set of glyph images, with each set containing an image for each character. For example, if a font has three sizes, and any combination of bold and italic, then there must be 12 complete sets of images.

            A brief history of using bitmap fonts

            The earliest user interface terminals such as teletype terminals used dot matrix printer mechanisms to print on rolls of paper. With the development of Cathode Ray Tube terminals bitmap fonts were readily transferable to that technology as dots of luminescence turned on and off by a scanning electron gun.

            Earliest bitmap fonts were of a fixed height and width with the bitmap acting as a kind of stamp or pattern to print characters on the output medium, paper or display tube, with a fixed line height and a fixed line width such as the 80 columns and 24 lines of the DEC VT-100 terminal.

            With increasing processing power, a more sophisticated typographical approach became available with vector fonts used to improve displayed text quality and provide improved scaling while also reducing memory required to describe the character glyphs.

            In addition, while a matrix of dots or pixels worked fairly well for languages such as English, written languages with complex glyph forms were poorly served by bitmap fonts.

            Representation of bitmap fonts in source code

            There are a number of bitmap font file formats which provide a way to represent a bitmap font in a device independent description. For an example see Wikipedia topic - Glyph Bitmap Distribution Format

            The Glyph Bitmap Distribution Format (BDF) by Adobe is a file format for storing bitmap fonts. The content takes the form of a text file intended to be human- and computer-readable. BDF is typically used in Unix X Window environments. It has largely been replaced by the PCF font format which is somewhat more efficient, and by scalable fonts such as OpenType and TrueType fonts.

            Other bitmap standards such as XBM, Wikipedia topic - X BitMap, or XPM, Wikipedia topic - X PixMap, are source code components that describe bitmaps however many of these are not meant for bitmap fonts specifically but rather other graphical images such as icons, cursors, etc.

            As bitmap fonts are an older format many times bitmap fonts are wrapped within another font standard such as TrueType in order to be compatible with the standard font subsystems of modern operating systems such as Linux and Windows.

            However embedded systems that are running on the bare metal or using an RTOS will normally need the raw bitmap character image data in the form similar to the XBM format. See Encyclopedia of Graphics File Formats which has this example:

            Following is an example of a 16x16 bitmap stored using both its X10 and X11 variations. Note that each array contains exactly the same data, but is stored using different data word types:

            My project uses MapStruct successfully when it does not include Flux or Flow streams. When I try to generate a mapper with a Flow or Flux, I receive an error: "error: The return type Flow is an abstract class or interface." Since Flow and Flux are interfaces, is there a way to still use MapStruct or do I have to roll my own mapper in this use-case?

            With MapStruct you can define mapping between different iterable. However, you can map from a nested listed into a top level list in a method (You can if it is wrapped though).

            In any case for this I would suggest doing the following:

            The Go code you provided will not impact the way how the Time instance will be serialized as you are parsing it back into Time after serializing it to a string.
