QUESTION
I had already set environment variable for the ffmpeg in my windows,want to embed the srt file into my mp4 file with ffmpeg:
...ANSWER
Answered 2022-Mar-26 at 21:10The parsing rules for FFmpeg filter graph are different from the rules used for other arguments.
Since 'e\sample\dance.srt'
is a value of a filter graph argument, we have to add an escape character before every special character:
QUESTION
Using the Temporal.Calendar of the upcoming proposal of the Temporal global Object, the following short function converts between calendar dates (the 18 Calendars recognized in Javascript).
Currently, the output date returned by Temporal.Calendar for other Calendars is in the format (example): '2022-02-25[u-ca=persian]'
How to avoid usingtoString().split("[")[0])
to get the calendar date without the suffix [u-ca=CalendarName]
as the Intl.DateTimeFormat()
does not recognize the suffix?
ANSWER
Answered 2022-Feb-25 at 18:33You can pass the Temporal.PlainDateTime object directly to Intl.DateTimeFormat, or indirectly by using Temporal.Calendar.prototype.toLocaleString(). This should save you from having to split the string to remove the brackets.
(A good rule of thumb is that if you find yourself doing string manipulation with the output of toString() from any Temporal object, or using new Date()
for that matter, it's probably a sign that there's a Temporal method you should be using instead.)
One caveat is that you have to make sure that the calendar of the locale matches the calendar of the date you are formatting. You can't use toLocaleString() or Intl.DateTimeFormat to do calendar conversion (unless it is from the ISO 8601 calendar). So you should use the withCalendar() method to convert the date to the calendar you want to output it in, as well as making sure the calendar in the Intl options matches it.
Here's my attempt at such a function:
QUESTION
I want to show Reality Composer experience on an image, however I don't want the AR Objects to hide when I lose track of the image, So I created an AnchorEntity and fetched the translation of the ImageAnchor from the didAdd anchors delegate method as follows:
...ANSWER
Answered 2022-Feb-19 at 14:09The problem is: in RealityKit 2.0 we don't have access to the Reality Composer's behaviors (except notification
), and the anchor type – we know that it's AnchorEntity(.image) – you assigned in Reality Composer works the same way as ARKit's image anchor in ARImageTrackingConfig, i.e. it uses local tracking instead of global tracking. In other words, hardly you get such a scenario with current Reality Composer scene.
Try ARKit and its ARWorldTrackingConfig for image tracking. All the "behaviors" must be recreated from scratch in RealityKit or in SceneKit.

QUESTION
The 3rd March 2022 is the end of this Hijri Month (month of Rajab for this year 1443 AH); i.e. 30 Rajab 1443 AH.
The month of Rajab for the year 1443 AH is 30 days in accordance with the Islamic (Hijri) Calendar in accordance with all websites, applications, MS Office, and Windows calendars.
When using the javascript Intl.DateTimeFormat()
to display the Islamic (Hijri) date for the 3 March 2022 using the islamic
calendar option, it will give the Islamic Hijri Date of (1 Shaʻban 1443 AH). This result is one day after the month of Rajab (i.e. the 1st of the following month) and it calculated the month Rajab to be 29 days rather than 30 days.
However, if the option passed to the Intl.DateTimeFormat()
is ar-SA
(i.e. arabic-Saudi Arabia), it will give the correct result. This is strange because the ar-SA
locale uses the Islamic (Hijri) calendar by default.
Is this an error/bug or is it the correct internal workings of javascript?
Is there a more robust method to get the Islamic Date in Javascript other than using the 'ar-SA' locale (but not using external libraries)?
See the code example below:
I have tested this in node and chrome and it gives the same resulting discrepancy.
...ANSWER
Answered 2022-Feb-06 at 07:29There are three possible reasons for the "off by one" date problems you're seeing:
- Time zone mismatch between date initialization and date formatting
- Using the wrong variation of the Islamic calendar (JS implementations typically offer 5 different Islamic calendars!)
- Bugs in the ICU library used for JS's calendar calculations
I'll cover each of these below.
1. Time zone mismatch between date initialization and date formatting
The most common reason for off-by-one-day errors is (as @RobG noted in his comments above) a mismatch between the time zone used when declaring the Date
value and the time zone used when formatting it in your desired calendar.
When you initialize a Date instance using an ISO 8601 string, the actual value stored in the Date instance is the number of milliseconds since January 1, 1970 UTC. Depending on your system time zone, new Date('2022-02-03')
can be February 3 or February 2 in your system time zone. One way to evade this problem is to use UTC when formatting too:

UPDATED CODE
...ANSWER
Answered 2022-Jan-13 at 02:14- In your situation, it seems that the values of
sku
ofcontainer
is not existing in the values ofsku
ofdata_obj
. I thought that the reason for your issue might be due to this. - As a script for checking this, you can use
const res = container.filter(e => !data_obj[e.sku])
for your script. In this case,[ { sku: 'L4943-0ULT', id: 3195, price: '5083.33' } ]
is returned. When this value is searched from your sample Spreadsheet,l4943-0ult
is found. In this case, the character case is different. By this, your issue occurs. I resulted in the reason of your issue is due to this.
When this issue was removed, how about the following modification?

ANSWER
Answered 2021-Dec-05 at 23:05Does it make sense to iterate through layers like this and keep adding files (to some target, does not matter for now) and deleting the added files in case they are found with a .wh prefix? Or am I totally off and is there a much better way?
There is a much better way, you do not want to reimplement (with worse performances) what Docker already does. The main reason is that Docker uses a mount filesystem called overlay2
by default that allows the creation of images and containers leveraging the concepts of a Union Filesystem: lowerdir
, upperdir
, workdir
and mergeddir
.
What you might not expect is that you can reproduce an image or container building process using the mount
command available in almost any Unix-like machine.
I found a very interesting article that explains how the overlay storage system works and how Docker internally uses it, I highly recommend the reading.
Actually, if you have read the article, the solution is there: you can mount
the image data you have by docker inspect
ing its LowerDir
, UpperDir
, WorkDir
and by setting the merged dir to a custom path. To make the process simpler, you can run a script like:

Install ARS
You can use ARS like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
