Digital is an easy-to-use digital logic designer and circuit simulator designed for educational purposes. There is no installation required, just unpack the Digital.zip file, which is available for download. On Linux start the shell script and on Windows and MacOS the JAR file can be started directly. A Java Runtime Environment (at least JRE 8) is required to run Digital. On Windows the easiest way to get Java is to install the AdoptOpenJDK.

QUESTION
I created the default IntelliJ IDEA React project and got this:
...ANSWER
Answered 2021-Nov-15 at 00:32Failed to construct transformer: Error: error:0308010C:digital envelope routines::unsupported
The simplest and easiest solution to solve the above error is to downgrade Node.js to v14.18.1. And then just delete folder node_modules and try to rebuild your project and your error must be solved.
QUESTION
I am using a company-hosted (Bitbucket) git repository that is accessible via HTTPS. Accessing it (e.g. git fetch) worked using macOS 11 (Big Sur), but broke after an update to macOS 12 Monterey.
*
After the update of macOS to 12 Monterey my previous git setup broke. Now I am getting the following error message:
...ANSWER
Answered 2021-Nov-02 at 07:12Unfortunately I can't provide you with a fix, but I've found a workaround for that exact same problem (company-hosted bitbucket resulting in exact same error).
I also don't know exactly why the problem occurs, but my best guess would be that the libressl library shipped with Monterey has some sort of problem with specific (?TLSv1.3) certs. This guess is because the brew-installed openssl v1.1 and v3 don't throw that error when executed with /opt/homebrew/opt/openssl/bin/openssl s_client -connect ...:443
To get around that error, I've built git from source built against different openssl and curl implementations:
- install
autoconf,opensslandcurlwith brew (I think you can select the openssl lib you like, i.e. v1.1 or v3, I chose v3) - clone git version you like, i.e.
git clone --branch v2.33.1 https://github.com/git/git.git cd gitmake configure(that is why autoconf is needed)- execute
LDFLAGS="-L/opt/homebrew/opt/openssl@3/lib -L/opt/homebrew/opt/curl/lib" CPPFLAGS="-I/opt/homebrew/opt/openssl@3/include -I/opt/homebrew/opt/curl/include" ./configure --prefix=$HOME/git(here LDFLAGS and CPPFLAGS include the libs git will be built against, the right flags are emitted by brew on install success of curl and openssl; --prefix is the install directory of git, defaults to/usr/localbut can be changed) make install- ensure to add the install directory's subfolder
/binto the front of your$PATHto "override" the default git shipped by Monterey - restart terminal
- check that
git versionshows the new version
This should help for now, but as I already said, this is only a workaround, hopefully Apple fixes their libressl fork ASAP.

QUESTION
I have a system with IoT Hub to ingests events from devices and Device Provisioning Service to provision devices. IoT Hub C# SDKs are used for the management of device tags and desired properties (IoT Hub device twins), and to invoke direct methods or schedule jobs.
Recently I've been experimenting with Azure IoT Central. While I don't plan to use it, I've found Digital Twins (that are being used on Azure IoT Central) to offer a very good way of managing IoT devices and I would like to emulate the same kind of functionality and capabilities on my IoT system.
The high-level architecture of IoT Central does not seem to indicate the services or logic used to manage Digital Twins.
As far as I understand, there are two ways you can start using Digital Twins:
- Plug and Play Digital Twins
- Azure Digital Twins service
Question - is Azure IoT Central purely based on Plug and Play Digital Twins and/or does it also use Azure Digital Twins service?
...ANSWER
Answered 2022-Mar-02 at 08:02Yes, IOT Central is purely based on plug and play Digital Twins
plug and play Digital Twins enables solution builders to integrate IoT devices with their solutions without any manual configuration.
Azure Digital Twins can be used to design a digital twin architecture that represents actual IoT devices in a wider cloud solution, and which connects to IoT Hub device twins to send and receive live data.

Answered 2022-Mar-10 at 17:44It appears you are using react-router-dom@6 so there are no longer any route props. In other words, props.match is undefined. Reading into props.match.params then throws the error.
Use the useParams hook to access the date route param.

QUESTION
I am building a Gatsby site. I upgraded Node.js to v17.0.1, and when I run a build, there is an error:
...ANSWER
Answered 2022-Jan-04 at 23:33Gatsby must be using an algorithm or key size which is no longer allowed by default with OpenSSL 3.0.
UPDATE ⚠️This is most likely a webpack issue - https://github.com/webpack/webpack/issues/14532
They have since released a fix in version 5.61.0 - https://github.com/webpack/webpack/releases/tag/v5.61.0 - so upgrading webpack should address the issue as well
A member of the webpack team has stated they do not plan to backport the fix to webpack 4, so if you are on webpack 4 you may need to look to upgrading to webpack 5 first.
From Node.js 17's announcement post:
If you hit an
ERR_OSSL_EVP_UNSUPPORTEDerror in your application with Node.js 17, it’s likely that your application or a module you’re using is attempting to use an algorithm or key size which is no longer allowed by default with OpenSSL 3.0. A new command-line option,--openssl-legacy-provider, has been added to revert to the legacy provider as a temporary workaround for these tightened restrictions.
Running this on the terminal might look like:
QUESTION
I'm trying to create a sound using Fourier coefficients.
First of all please let me show how I got Fourier coefficients.
(1) I took a snapshot of a waveform from a microphone sound.
- Getting microphone: getUserMedia()
- Getting microphone sound: MediaStreamAudioSourceNode
- Getting waveform data: AnalyserNode.getByteTimeDomainData()
The data looks like the below: (I stringified Uint8Array, which is the return value of getByteTimeDomainData(), and added length property in order to change this object to Array later)
ANSWER
Answered 2022-Feb-04 at 23:39In golang I have taken an array ARR1 which represents a time series ( could be audio or in my case an image ) where each element of this time domain array is a floating point value which represents the height of the raw audio curve as it wobbles ... I then fed this floating point array into a FFT call which returned a new array ARR2 by definition in the frequency domain where each element of this array is a single complex number where both the real and the imaginary parts are floating points ... when I then fed this array into an inverse FFT call ( IFFT ) it gave back a floating point array ARR3 in the time domain ... to a first approximation ARR3 matched ARR1 ... needless to say if I then took ARR3 and fed it into a FFT call its output ARR4 would match ARR2 ... essentially you have this time_domain_array --> FFT call -> frequency_domain_array --> InverseFFT call -> time_domain_array ... rinse N repeat
I know Web Audio API has a FFT call ... do not know whether it has an IFFT api call however if no IFFT ( inverse FFT ) you can write your own such function here is how ... iterate across ARR2 and for each element calculate the magnitude of this frequency ( each element of ARR2 represents one frequency and in the literature you will see ARR2 referred to as the frequency bins which simply means each element of the array holds one complex number and as you iterate across the array each successive element represents a distinct frequency starting from element 0 to store frequency 0 and each subsequent array element will represent a frequency defined by adding incr_freq to the frequency of the prior array element )
Each index of ARR2 represents a frequency where element 0 is the DC bias which is the zero offset bias of your input ARR1 curve if its centered about the zero crossing point this value is zero normally element 0 can be ignored ... the difference in frequency between each element of ARR2 is a constant frequency increment which can be calculated using
