            How to reformat a corrupt json file with escaped ' and "?
            Asked 2021-Jun-13 at 11:41

            Problem

            I have a large JSON file (~700.000 lines, 1.2GB filesize) containing twitter data that I need to preprocess for data and network analysis. During the data collection an error happend: Instead of using " as a seperator ' was used. As this does not conform with the JSON standard, the file can not be processed by R or Python.

            Information about the dataset: Every about 500 lines start with meta info + meta information for the users, etc. then there are the tweets in json (order of fields not stable) starting with a space, one tweet per line.

            This is what I tried so far:

            1. A simple data.replace('\'', '\"') is not possible, as the "text" fields contain tweets which may contain ' or " themselves.
            2. Using regex, I was able to catch some of the instances, but it does not catch everything: re.compile(r'"[^"]*"(*SKIP)(*FAIL)|\'')
            3. Using literal.eval(data) from the ast package also throws an error.

            As the order of the fields and the legth for each field is not stable I am stuck on how to reformat that file in order to conform to JSON.

            Normal sample line of the data (for this options one and two would work, but note that the tweets are also in non-english languages, which use " or ' in their tweets):

            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

            Answered 2021-Jun-12 at 16:19

            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:

            How to move older clickhouse partitions to S3 disk
            Asked 2021-Jun-12 at 15:18

            I'm currently starting to work with clickhouse for our in-house analytics system, but it looks like there are no automated ways to configure policies for data retention. The only thing I saw was the ALTER ... MOVE PARTITION (https://clickhouse.tech/docs/en/sql-reference/statements/alter/partition/#alter_move-partition), but it looks like the process has to be manual / implemented in our application layer.

            Is there any native way to do so directly in clickhouse with storage policies?

            A scalar float/double is just the bottom element of an XMM/YMM register already, and there are various FP shuffle instructions including vinsertps and vmovlhps that can (in asm) do the insertion of a 32-bit or 64-bit element. There aren't versions of those which work on 256-bit YMM registers, though, and general 2-register shuffles aren't available until AVX-512, and only with a vector control.

            Still much of the difficulty is in the intrinsics API, making it harder to get at the useful asm operations.

            One not-bad way is to broadcast a scalar float or double and blend, partly because a broadcast is one of the ways that intrinsics already provide for getting a __m256d that contains your scalar1.

            Immediate-blend instructions can efficiently replace one element of another vector, even in the high half2. They have good throughput and latency, and back-end port distribution, on most AVX CPUs. They require SSE4.1, but with AVX they're always available.

            (See also Agner Fog's VectorClass Library (VCL) for C++ templates for replacing an element of a vector; with various SSE / AVX feature levels. Including with runtime-variable index, but often designed to optimize down to something good for compile-time constants, e.g. a switch on the index like in Vec4f::insert())

            The problem is caused by the fact that the comparison is done on the server using the server-side collation, and you can't change that through EF's linq provider (which is why the overload with the StringComparison argument fails). The collation is case-insensitive, but of course, being Turkish, considers 'i' and 'I' to be different characters.

            The solution is to stop trying to change the case of the product names in the database and instead modify the search criterion.

            Since none of the data being searched contains 'İ', the modification is simple: call ToUpper() on the search value, and make certain that the conversion isn't done with Turkish culture. For example, if the default culture on the client isn't Turkish, you can just use
