QUESTION
I'm producing a game In the part of my game lobby, the list of openers in that room is received using the web socket If the time interval is even 2 seconds between receiving the specifications, the work will be done without any problem, but if all the specifications are received at the same time, the MakeUILobby function will not work!
...ANSWER
Answered 2021-Jun-13 at 08:27Your issue is value capturing in lambda expressions.
The value of field WSUserJoinedToRoom
is changed every time when receiving the last item so when the main thread frame playes it will execute both lambda actions which will both access the same WSUserJoinedToRoom
value.
So in your case
- player 3 is received and stored into
WSUserJoinedToRoom
and you add the callback action - player 1 is received and stored into
WSUserJoinedToRoom
and you add the callback action - now the main thread executed Update and executes both actions which do read the
user_id
anduser_name
from the currentWSUserJoinedToRoom
(player 1), not the one it was when the callback wasEnqueue
d!
Instead either store the two strings in local variables before:
QUESTION
Hi I am developing a runtime using Substrate-FRAME and I would like to know how can I write a system test for my runtime?
The main purpose of writing a system test is to ensure that the final build is fulfilling all of the required specifications and also to ensure nothing is compromised on a runtime upgrade. The idea for me is something similar to point no. 2 mentioned in this thread.
Any documentation regarding this type of tests would be greatly helpful.
Update:
I ended up using py-substrate-interface
to make test scenarios. Now I can automatically deploy nodes to form a network (thanks to Python) and run my custom system test scenarios. Very useful tool for developing runtimes in Substrate.
ANSWER
Answered 2021-Apr-14 at 16:18There is an overview here on the DevHub
And there are examples throughout substrate that include tests.rs
and mock.rs
files to use as reference.
If you have not already, checkout the create a pallet tutorial and the recipes all have some tasty examples to look at for these as well.
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
As far as I know, the v8 engine is based on ECMAScript language specifications, do you develop it with a new ECMAScript whenever a new ECMAScript is released?
Or do we add only the newly added functions?
For example, if you look at ES5 -> ES6, in the case of Execution Context, the components change, but do you change all of them?
...ANSWER
Answered 2021-Jun-10 at 09:51(V8 developer here.)
Both the ECMAScript standard itself and engines' implementations of it evolve by adding individual features one by one.
The "TC39" committee discusses new proposed features. Once a feature has been agreed upon, it is added to the standard (see the "Process" document @Bergi linked in his comment for more details). The yearly "releases" of ECMAScript are just snapshots of this continuous process.
Engines typically implement a new feature either shortly before it is finalized (so that implementation feedback can inform the standardization discussion) or shortly after.
Rewriting an entire JavaScript engine from scratch every year would be a huge waste of effort: most of the language doesn't change. Also, rewriting an entire JavaScript engine from scratch would take many years. (In fact, rewriting any software from scratch is almost always a bad idea, because you'll spend a huge amount of time just catching up with what the old version was able to do. Incremental improvements are almost always the better strategy.)
The majority of engine developers' time is typically spent on improving support for existing features and subsystems (compilers, garbage collectors, internal object model, ...), such as making them faster or more memory efficient.

QUESTION
I'm using the DocuSign eSignature API, and am generating client code with the help of the openapi codegen (via these https://github.com/docusign/OpenAPI-Specifications).
Now I have to use the DocuSign Manage API (https://developers.docusign.com/docs/admin-api/), too, but I can't find any Swagger / OpenAPI definition for that?
Is it somewhere hidden, does it not exists, and are there plans to make it available at one point? Are there any other options, SDKs, anything or do I have to make these calls "manually"?
...ANSWER
Answered 2021-Jun-07 at 14:19Unfortunately, the Swagger file for the Admin API is not yet available. That's also why DocuSign doesn't yet have SDKs for the API yet. I don't have access to any scheduling information on it.
I suggest that you handle any Admin API calls you need to do manually for now.
What language are you creating SDKs for with CodeGen? (Please answer in a comment or by editing your original question.)

Context of the problem I am taking a course at www.platzi.com, and in this chapter they are teaching us the logic and operation of token web authentication. So the code shown below is as shown in the course.
The flow of the code is as follows:
You have a resource server called "server.php" this server takes care of the resources you have. There is a route server called "router.php" this server is in charge of receiving the requests, give it to the resource server called "server.php" There is a server for authentication called auth_server.php, this server has two functions:
- Create a token when the user goes to login
- Validate The token that the user supplies to the resource server called server.php
