QUESTION
I am writing a program in python to have a user input multiple websites then request and scrape those websites for their titles and output it. However, when the program surpasses 8 websites the program crashes every time. I am not sure if it is a memory problem, but I have been looking all over and can't find any one who has had the same problem. The code is below (I added 9 lists so all you have to do is copy and paste the code to see the issue).
...ANSWER

header to the headers=
parameter in requests.get()
, otherwise, the page thinks that your a bot and will block you.

are all focusing on xnor
but only 15b
seems to be correct when I attempt to check.
For reference:
...ANSWER
Answered 2021-Jun-14 at 21:0415b is the definition of XNOR in conjunctive normal form. 15c is the negation of XNOR (i.e., XOR) in disjunctive normal form. You can derive this using De Morgan's laws, which state
'(XY) == 'X + 'Y
'(X + Y) == 'X'Y
Using these laws, we can first write 15b

I want to print some text before redirecting my response to google search link..but I am unable to print it.My code for redirecting servlet is as below:
...ANSWER
Answered 2021-Jun-14 at 02:22sendRedirect
is sending a response code like 302 or 304 (I assume 302 Temporary Redirect) to the browser and a Location
header telling the client where to go instead. This is then handled transparently by the browser, without it ever having to display anything.
To see the HTTP response for yourself use curl -v http://yourendpoint
, or use Postman if you prefer a browser based tool. Or you can look at the request/response in your browser dev tools, under the network tab (you might have to find an option that doesn't clear the inpector history on page load).
Alternatively you would pass the redirect url to the page and do the redirect later with javascript.
You could respond with something like this, to display the page and redirect after 3 seconds:
QUESTION
I have an MS Access report that contains records of clients from one table (including the email address) and linked grouped records from other tables fetched by a Query.
I want to send the content of the report to each client separately in the body of the email (not as an attachment), I am able to get the text put in the body of the email but without the formatting and without the picture in the header.
I used the following code which runs behind a click of a button. I would appreciate if anyone can help with the formatting issue AND if there is a way I can automate sending the emails for my 200+ clients without clicking the button each time (like a loop or something):
...ANSWER
Answered 2021-Jun-13 at 22:17Since MS Access reports are specialized rich text formats, conversion to HTML is not easily available. You would need to rebuild your report with HTML markup. However, there is another approach.
Consider creating an Outlook email template (.oft) with all needed images, colors, fonts, and other formatting with placeholders such as %...%
markers:
Dear %ClientName%:
Thank you for purchase of %product% for %totalsales% on %salesdate%. We appreciate your business of %years% years.
%salestable%
Best wishes,
MyCompany Management
Then, have MS Access loop through a recordset of email details and text for message body to fill in placeholders. Handle any date/current/percent formatting in SQL or VBA. Because you need a group level multi-record summary, run two loops at 1) client level and 2) sales level.
QUESTION
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 questionWhat 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 questionAre 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 farThe KeDei TFT library came with an a bitmap font table that was defined as
...ANSWER
Answered 2021-Jun-12 at 16:19Raster 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:
QUESTION
I'm running into an issue where I get different results on Linux (tested with Ubuntu) and Windows.
I created https://github.com/benrobot/EncodingTests to showcase the issue I'm experiencing.
On Windows, calling System.Text.Encoding.UTF8.GetBytes("’")
returns the correct 3 bytes (0xE2, 0x80, 0x99
per https://www.fileformat.info/info/unicode/char/2019/index.htm) but on Linux (tested on Ubuntu) the
returned bytes correspond to � (0xEF, 0xBF, 0xBD
per https://www.fileformat.info/info/unicode/char/fffd/index.htm).
Shouldn't .NET Core behave the same on both operating systems?
...ANSWER
Answered 2021-Jun-12 at 16:19It turns out file encoding was the problem. My .cs file was ANSI (Windows-1252) encoded. When I added UTF8 encoded versions of the same test they passed on both operating systems.
Here's a screenshot showing Notepad++ with circles around the file encoding:
The solution was to use Notepad++ menu option Encoding -> Convert to UTF-8 to convert the file to a format acceptable in Linux.
QUESTION
I was reading about the vulnerability of deserializing types with Json.Net using a setting different from TypeNameHandling.None
. The Json.Net docs recommend implementing a custom SerializationBinder
. A simple example of a custom binder that checks types against a list of known types is given here.
While this solution certainly works, the set of known types is not fixed in my scenario, since the application has to support extensions, which might define their own data classes. One solution would be to extend the known type list during the registration of an extension, however, I had a second approach in mind, that I'd like to verify:
I want to define a common interface for trusted types:
(suggested by dbc: A custom attribute could be used instead of a marker interface.)
...ANSWER
Answered 2021-Jun-11 at 15:15When you encounter a type that isn't marked, it is not sufficient to check its generic type arguments, you need to check the type of every public property and every parameter of a public constructor, because these are the serialization footprint.
For example, you really do not want to allow deserialization of a System.Data.TypedTableBase
even if T
is safe, because it has public properties that allow configuring database access.
