QUESTION
I only know C programming. Using C programming, I want to build my own library (to control my Display and Speakers) that's specifically useful for my projects.
I don't want any readymade libraries with different features, I just want direct control to every pixel of a computer (atleast my computer's display, I will think about cross platform later) and every vibration of my speaker(s).
How can I get this?
First Edit: After getting some informations in the comment-section/answers, I came to an understanding that in modern computers, direct access is not possible as every aspect regarding Display and speaker is controlled by the OS, and I can only request the OS to display a graphics in it's Window or play a sound by pre-encoding my sound in one of the supported audio formats (correct me if I'm wrong).
Now, let's change the scenario. I have my Display (with its driver hardware), my speaker (with its driver hardware), and a Micro-controller.
Now, by coding my own OS and booting it in my microcontroller, can I get direct control to every pixel of a computer and every vibration of my speaker(s).
...ANSWER
Answered 2022-Mar-25 at 16:17You can't. You have to get the OS to do it for you - in fact, that's the entire point of an OS. And that means either making system calls directly from assembly code (hard on Linux; practically impossible on Windows because they are undocumented) or using a library to tell the OS to do things.
You are probably interested in using a library that's as close to the OS as possible - "batteries not included" - so in Linux that would be something like ALSA (sound) and XCB (graphics) rather than something like Qt.
You can minimize your library usage - for example, if you make an array of pixels, and you only tell the OS "please create a window" and "please draw these pixels in my window" and "please play this sound data".
Of course it is also possible to tell it to make your program fullscreen so that the user can't see anything else. This is usually done by making a window and then making the window fullscreen. Linux does actually have ways to get more direct screen control - accessing the screen as a "framebuffer device" - but if you use this, you can't run any other graphics programs at the same time (not even the desktop). And you are still asking the operating system to put pixels on the screen - not talking to the hardware.
If you want to write a program that doesn't run with an OS, that's a completely different question (and still difficult).
QUESTION
I am creating a calculator app to help with decimals and would like something to two decimal places like below:
...ANSWER
Answered 2022-Feb-21 at 22:12From your question it is not clear where you want to perform the conversion. However, this should get you on the right track.
Both toFixed()
and toPrecision()
return a string representing a number. It's clear that you can't use the string for further calculations. In order to do so, use parseFloat()
to get the floating point number from the string.
QUESTION
As mentioned in my question title, I'm trying to run pod install
following an update to React Native 0.66, and I keep getting the following error:
ANSWER
Answered 2021-Oct-20 at 14:40I recently encountered a similar issue with boost after updating react native. After the panic wore off, and some good coffee, I was able to resolve by doing the following:
- Open the
/ios/.xcworkspace
file in Xcode. - Raise the iOS Deployment Target (in my case I only bumped to 10).
- Product > Clean Build Folder, then Product > Run.
- Locate the boost error in the issue navigator and identify which pod the error is listed under (in my case it was RNReanimated).
- Update the node package related to the pod (in my case,
npm update react-native-reanimated
- Finally, run
pod install
After performing those steps, I was able to get my project up and running again.
QUESTION
After updating my npm packages, some of the imports from the 'vue' module started showing errors:
TS2305: Module '"../../node_modules/vue/dist/vue"' has no exported member 'X'
where X is nextTick, onMounted, ref, watch etc. When serving the project, Vue says it's "failed to compile". WebStorm actually recognizes the exports, suggests them and shows types, but the error is shown regardless. Some exports like computed and defineComponent work just fine.
What I've tried:
- Rollback to the previously used Vue version "3.2.2" > "3.0.11". It makes the abovementioned type errors disappear, but the app stops working entirely, showing lots of
TypeError: Object(...) is not a function
errors in console and not rendering the app at all. In the terminal, some new warnings are introduced:"export 'X' (imported as '_X') was not found in 'vue'
where X is createElementBlock, createElementVNode, normalizeClass and normalizeStyle. - Rollback other dependencies. None of the ones that I tried helped fix the problem, unfortunately.
- Manually declare the entirety of 'vue' module. We can declare the 'vue' module exports in shims-vue.d.ts, and it actually makes the errors disappear, however, this seems like a terrible, time-consuming workaround, so I would opt out for a better solution if possible.
My full list of dependencies:
...ANSWER
Answered 2021-Aug-15 at 13:53That named exports from composition API are unavailable means that vue
is Vue 2 at some place which has only default export. Since Vue 3 is in dependencies
and both lock file and node_modules
were refreshed, this means that Vue 2 is nested dependency of some direct dependency.
The problem needs to be investigated in lock file. It shows that @vue/cli-plugin-unit-jest@4.5.13
depends on vue-jest@3
which depends on vue@2
.
A possible solution is to upgrade @vue/cli-plugin-unit-jest
to the latest version, next
. The same likely applies to other @vue/cli-*
packages because they have matching versions.

I've been trying to write a simple vibration app for my Samsung Galaxy 4 watch but am having an issue. The watch will not vibrate when the screen is off. It will only vibrate when my application is open. Any ideas why this is? Here is some of my code:

QUESTION
It is possible to use org.apache.spark.sql.delta.sources.DeltaDataSource
directly to ingest data continuously in append mode ?
Is there another more suitable approach? My concern is about latency and scalability since the data acquisition frequency can reach 30 KHz in each vibration sensor and there are several of them and I need to record the raw data in Delta Lake for FFT and Wavelet analysis, among others.
In my architecture the data ingestion is done continuously in a Spark application while the analyzes are performed in another independent Spark application with on-demand queries.
If there is no solution for Delta Lake, a solution for Apache Parquet would work because it will be possible to create Datasets in Delta Lake from data stored in Parquet Datasets.
...ANSWER
Answered 2022-Jan-15 at 19:05Yes, it's possible and it works well. There are several advantages of Delta for streaming architecture:
- you don't have a "small files problem" that often arises with streaming workloads - you don't need to list all data files to find new files (as in case of Parquet or other data source) - all data is recorded in the transaction log
- your consumers don't see partial writes because Delta provides transactional capabilities
- streaming workloads are natively supported by Delta
- you can perform DELETE/UPDATE/MERGE even for streaming workloads - it's impossible with Parquet
P.S. you can just use .format("delta")
instead of full class name

ANSWER
Answered 2021-Dec-26 at 11:34VIBRATOR_MANAGER_SERVICE
was added in API level 31 (Android 12) and devices running on lower API levels know nothing about it.
On older API levels you can use VIBRATOR_SERVICE
instead to retrieve a Vibrator
(rather than a VibratorManager
).
QUESTION
I need to customize my layout which is root_preferences
.
for instance: set gravity for SwitchPreferenceCompat or EditTextPreference.
It is the first time that I use setting fragment and I think both settingFragment
and root_Perfenses
are not like ordinary fragments, I can't give it Id, I can't set gravity.
My settingFragment class:
...ANSWER
Answered 2021-Nov-02 at 15:00now I want to set gravity of
to center, I know it is not common to do this.
Do do this you need to create a custom layout that has a TextView
for the title with an id of title
and normally set the gravity with android:gravity
. Also you can use other TextView
attributes that you can't use within the preference xml
For example:
QUESTION
My application starts a service that detects phone shaking. When the service detects a shake, it searches for a BT device within range and if a suitable device is found, it connects to it and sends data to it.
To check if the system is killing the service, I turn on the vibration when it detects shaking.
Everything works fine when Activity is on the main screen. However, when I close Activity, the service detects shaking, but the device search does not start (BroadcastReceiver onReceive does not receive any Intent).
Are there any limitations to searching for Bluetooth devices from the background service? How can this be solved?

I'm getting the error message
...ANSWER
Answered 2021-Oct-18 at 06:57We must specify schema when creating a streaming source DataFrame.
From the documentation:
By default, Structured Streaming from file based sources requires you to specify the schema, rather than rely on Spark to infer it automatically. This restriction ensures a consistent schema will be used for the streaming query, even in the case of failures.
