controllerThread sets the suspendRequested flag to true when it wants to pause threadA. threadA checks this flag if it's in run() method and, if it's set, it enters a waiting state using wait() or Thread.sleep(). To resume threadA, the controlling thread sets suspendRequested back to false and calls notify() to wake threadA up.

Try running the command from git bash, not CMD.
There is some misunderstanding, in that there never is a "user" [IIS AppPool\{AppPoolName}].
[IIS AppPool\{AppPoolName}] is a "virtual account", & is completely 'unmanaged' by IIS/Windows, and as such is not available via normal means. I think they could have named it better, because the word "account" is a bit of a misnomer (in the traditional sense). It's really a "deterministic unmanaged SID", which windows will let you use in security contexts as if it 'were' an account/user.
Aside/Details: Therefore, Microsoft/WindowsTeam does not have a process which keeps an easily accessible record of all of the "virtual account(s)" that have executed (as there is no 'creation', just 'usage'; a chicken with no egg). This is hack is possible due to the role of SIDs in Windows combined with the deterministic nature of the SIDs generated for the "virtual account in question". It's just a SID prefix based on the account class (i.e. [IIS AppPool\*] === S-1-5-82-*) combined with the UInt32 representation of the SHA-1 of the (lowercase, for IIS AppPool; uppercase, for other services) username.
This is why, when creating permissions in MSSQL Server for an IIS AppPool, the documentation states:
!!!DO NOT CLICK SEARCH!!!
How to add the ApplicationPoolIdentity to a SQL Server Login https://learn.microsoft.com/en-us/archive/blogs/ericparvin/how-to-add-the-applicationpoolidentity-to-a-sql-server-login
... as you can't search (or verify) that it exists, because it only 'exists' when you're using it. So while there will be traces of a virtual account's existence (i.e. the traces it leaves behind as it's bound to an executing service {in logs}, in configuration files, & usually the permissions created on resources for it to be effective). The "deterministic unmanaged SID" only 'exists' at "run time" of the service (and most often will not have a user profile). For instance, if you create a new AppPool, but don't actually start it; there won't be a trace it was there (via icacls.exe, below). However, as the AppPool is running you will see the 'virtual account / user' in task manager for w3wp.exe, as well as the config entry.
So now that that's "clear", let's dig into the question, "So the question is, how do I check that these IIS AppPool service accounts exist in Powershell?" .. because "{you} need to configure databases to automatically grant permissions to the correct account for IIS".
Short Answer -- You Don't (& don't "need" to).
Longer Answer -- If you're using MSSQL, you can follow the instructions above ("How to add the ApplicationPoolIdentity to a SQL Server Login") prior to even creating the Application Pool!
If you're using some other resource (db, file, etc.), you can do the following to bind the SID to a local group, & then use the GUI to apply access to that group:
# PowerShell AS Admin ->
# ADSI === System.DirectoryServices.DirectoryEntry
$group = [ADSI]"WinNT://$Env:ComputerName/{SomeSecGrpName},group"
Write-Host $group.Path
# group === WinNT://{ComputerName}/{SomeSecGrpName},group
$newAppPoolName = "SomeAppPoolName"
$ntAccount = New-Object System.Security.Principal.NTAccount("IIS APPPOOL\$newAppPoolName")
Write-Host $ntAccount
# $ntAccount === IIS APPPOOL\SomeAppPoolName
$strSID = $ntAccount.Translate([System.Security.Principal.SecurityIdentifier])
Write-Host $strSID
# $strSID === S-1-5-82-1567671121-388969313-3181147451-2359319770-4988630401
# $strSID - note - not a valid SID above
$user = [ADSI]"WinNT://$strSID"
$group.Add($user.Path)
... then use the group "SomeSecGrpName".
However, lets say you want to know if the IIS AppPool ever ran and/or you want an easy way to get access to the SID; which you can then use to secure items. You can do the following:
Ensure Security Isolation for Web Sites https://learn.microsoft.com/en-us/iis/manage/configuring-security/ensure-security-isolation-for-web-sites
icacls.exe c:\inetpub\temp\appPools\{SomeAppPoolName}\{SomeAppPoolName}.config /save {d:\SomeDirectory}\icacls_{SomeAppPoolName}_output.txt
... gets us a file, containing the SID to use for security permissions.
From Microsoft documentation, I understand that it is essential to ensure that the begin and end functions are accessible in the same namespace as your container. This accessibility allows the compiler to locate these functions through Argument-Dependent Lookup (ADL).
MYSQL decides the relevant strategy: MATERIALIZATION (or) DUPSWEEDOUT based on the cost even if we force it (according to MySQL manuals for SEMIJOIN Hint). On the other hand, there is another Hint SUBQUERY, which you can use since nested subqueries are present in your query, which uses the materialization strategy.
The modified code below will use the MATERIALIZATION strategy:
EXPLAIN FORMAT=TREE
SELECT /*+ **SUBQUERY(@subq2 MATERIALIZATION)** */ rse.*
FROM rubric_session_elements rse
WHERE rse.rubric_session_id IN (
SELECT /*+ QB_NAME(subq2) */ rs.id
FROM rubric_sessions rs
WHERE rs.template_id IN (
SELECT /*+ QB_NAME(subq1) */ a.rubric_template_id
FROM activities a
WHERE a.group_id = 123
)
);

You can use lnk-cli to create a directory link.
Here’s my setup using TypeScript:
.ts files I want to share)Only include the code files you want (no
package.json,tsconfig.json, etc.)
See the highlighted text. Just add the "lnk" command to create the directory link before watching the TypeScript files.
The
commonfolder has the main code, so you can ignore these linked folders. Any changes in one of the three locations (common, functions/common, or server/common) will automatically reflect in all linked locations.
Now you can import the common files like this. (No additional need to adjust tsconfig.json)
After you set the visibility to GONE, add
ConstraintLayout.LayoutParams layoutParams = (ConstraintLayout.LayoutParams) tvQuestion.getLayoutParams();
layoutParams.topToBottom = R.id.tvQuestionNumber;
tvQuestion.setLayoutParams(layoutParams);
after asking around my question on Image.sc forum, I found that the problem can be solved if I downgrade keras from 3.6.0 to 3.4.1 (Google Colab version).
However, the bad news is that a new bug appeared. When I set
discriminator.compile(loss = "binary_crossentropy", optimizer = Adam(learning_rate = 0.0002, beta_1 = 0.5), metrics = ["accuracy"])
# Set non-trainable after compiling discriminator
discriminator.trainable = False
discriminator still becomes non-trainable even if it had been compiled before turning off the trainable tag, and no re-compilation of the discriminator afterwards. Please refer to discriminator.summary() before and after turning off the trainable flag.

Sorry @jcalz, I was to answer you specifically yesterday but was too tired and simply forgot it.
Yes, what you mention on your comment is what I was after. Little I knew I was taking TS to it's pants, so I finally plan to settle on something like this:
[
/* One entry */
{
string: 'foo',
function_1 (x) {
let ret : number = x;
return (ret);
},
function_2 (x) {
let ret: number = x;
return (ret);
}
},
/* Another entry */
...
]
This is a construction I've seen for example, in prosemirror's schema (except for mine's being inside an array). If that's also a problem I'll then reparent these with an object and get rid of the array altogether.
For those calling it laziness: I wouldn't have devoted a whole day to try to solve this if that was the particular case.
Well, thank you all for you time and you attention!

This is a network issue. You can first check if the API URL is accessible using the code in this thread.
Well, this error is familiar, because it gave me sleepless nights. 415 Unsupported Media Type. I think this means that the content type of the request doesn't match what spring-boot expects. Since you've confirmed that your BE API works, I suspect tat the issue is in how React is making the request. Just making educated guesses here. Here are a few things you can try:
Check that the field names in your FormData match the param names in your controller. FormData (caption, file, and postTypeName)
Please check your axios version. I put this here because some versions of axios have known issues with FormData
Remove Content-Type header I think because axios automatically sets the Content-Type header to multipart/form-data with a boundary, which is essential for FormData to work properly. Manually setting Content-Type can interfere with this. So Try removing 'Content-Type': 'multipart/form-data' from the headers like this:
const response = await axios.post(url, formData, {
headers: {
"Authorization": `Bearer ${token}`,
},
});
postTypeName in FormData instead of RequestParam: Since you've currently added postTypeName as a RequestParam, it might not work as expected in a FormData object. Instead, please ensure that postTypeName is added as a RequestPart parameter in your controller. Do you understand?I would also improve your addPostWithImage endpoint like this.
@PostMapping(value = "/posts/add", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
@ResponseStatus(HttpStatus.CREATED)
@ApiResponse(responseCode = "400", description = "Please check the payload or token")
@ApiResponse(responseCode = "200", description = "Post added with image")
@Operation(summary = "Add a new Post with optional image")
@SecurityRequirement(name = "studyeasy-demo-api")
public ResponseEntity<?> addPostWithImage(
@Parameter(content = @Content(mediaType = MediaType.APPLICATION_JSON_VALUE)) @RequestPart("caption") PostPayloadDTO postPayloadDTO,
@RequestPart(value = "file", required = false) MultipartFile file,
@RequestPart("postTypeName") String postTypeName, // I changed this from RequestParam to RequestPart
Authentication authentication) {
...
}
These are some of the issues I could immediately spot with your code. Try and change them and please let me know.
I fix the similar issue by installing the referenced dlls from NuGet.
My case was like: LibraryA needs System.Runtime(6.0.0.) but somehow the dll path

The answers here are not wrong, but not precise either. Your problem has nothing to do with the BigDecimal class as such, but with the nature of doubles.
A double is internally represented as an exponential, you could imagine the computer storing something looking like 0.22 * 2^15. However not every number can be represented accurately this way (for your case see: https://www.binaryconvert.com/result_double.html?decimal=049051053046054057). This inaccurate representation is what you pass to the BigDecimal constructor.
In conclusion, the input argument for your BigDecimal constructor is the approximation that you see in the end. The BigDecimal constructor did nothing wrong, its input was inaccurate.
The UAC will come always, try to run this in admin, right click run as admin or change the app executable or the apps entire folder and give it all elevated administrator permissions. Then UAC prompt will be skipped, or if you as I can see are already using Auto Hotkey, there are many scripts available for this, where it automatically clicks Yes (Button 1) when it detected the UAC admin prompt, you can activate it keeps running on loop and that's good for you, or if you can, disable UAC, [DON'T, this is last resort.]

You can do this without needing to use the gcloud CLI/API. You can add this role to your user through the IAM section however you need to make sure you're in the settings for your organization, not your project. The dropdown at the top of the page will let you switch over and then the role will be visible when you search for them on the right side.

Well, useRef is a hook in React for functional components. It has function that provides a mutable reference to a DOM element. Creating a ref without useRef just uses the React.createRef() method. The typical difference between them is that we normal use useRef hook for the functional component and the Creating a ref without useRef for the class component. And the second difference is that createRef method creates a new ref object each time the component re-renders but the useRef hook only returns the same ref object through the component's lifecycle so doesn't need the re-render. I think the benefit of useRef is that it can have any mutable value without causing a re-renders unlike the createRef method.
The reason is because of the node version. The solution is to use lts. I was using the latest.
Have you tried using this solution from a bit of an older post?
The post was: Stackoverflow Post which was based on this blog from 2015. The way this post outlines on fixing the issue is by manually compiling OpenCV yourself. (By my understanding). You could also try checking the official docs to compile with that: OpenCV Docs
If this doesn't work however you could try just cloning the github repo (I know not the greatest way but it should work..)
$ sudo apt-get install git
$ git clone https://github.com/opencv/opencv.git

During troubleshooting, I noticed that using the AWS CLI instead of Boto3 gave slightly different output. I tried running the script within the same account for both the EC2 client and Network Manager, and it worked. It seems Boto3 is performing a check to ensure that the core network and VPC are in the same account, but it's throwing an incorrect error, indicating a "wrong input."
As Robert mentioned in the comments, this depends on certain parameters sent to Google Play when requesting the download link. Based on my research, the key parameter is Vending.version, which specifies the version of Google Play that is making the download request. The last version that can request the app without split APKs is 80913000, which represents a specific Google Play version. After this version, it’s no longer possible to download a solid APK.
Additionally, some apps have implemented restrictions within themselves, so even setting this parameter to 80913000 won't allow the app to be downloaded. You can see this in the link below, where, starting from a certain app version, even on ApkCombo, downloading a unified APK file is no longer possible:

If you need really good compression , I’ve used on ChatGPT “SentenceSqueezer”, it usually compresses in neighborhood 60-85% of instruction sets and it’s so simple, guaranteed not to lose context because it makes an acronym out of each sentence or line , tell it to leave periods in there place or whatever you desire, gives pre and post count with a mapping table, and it may do meta compression using one symbol. The other one is “Tokenizer GPT Instruction Compressor” also in the same platform but uses single placeholders for words that repeat more than 3 times I. BElieve, outputs same stats on compression mapping table etc, may be worth a try, I’m new so I may be way off if this will work for you, hopefully so.

To access your Laravel Herd apps from a Docker container, create a shared network using docker network create my-network. Run both your Laravel Herd apps and the Docker container on this network. Inside the container, you can access myapp1.test by its IP address or hostname, which should be resolvable within the network. For more complex setups, consider using Docker Compose to define services, networks, and dependencies.

but as you can see, no one function. I can't set a width in pixels or percentage as the 3 columns haven't got the same length of text, and if i set the width to "fit-content" for the parent div, it's OK, the space is redistributed like i want but when the text wrap on 2 lines the H1 tag don't take the width of the text but add extra space on the right (maybe the browser don't be able to calculate the new width ?!).

When you are giving the child class a parent to inherit from, in this case; Parent, it literally inherits everything Parent has; it's attributes, methods, more. In this case you are REASSIGNING attribute which is already defined since you grabbed it from Parent. Therefore you would need to do attribute2 = attribute / 2 or attribute /= 2.

It seems Apache isn't loading the PHP extension correctly. First, make sure Apache is using the correct php.ini by checking phpinfo() in the browser. In your php.ini, try using extension=zip.so instead of the full path. After making changes, restart Apache with sudo apachectl restart. If it still doesn’t work, check Apache’s error logs (/var/log/apache2/error_log) for more details. This should make ZipArchive available in both the command line and the browser.

Stability Across Renders: Without useRef: A plain object ({ current: undefined }) is recreated on each render, so it doesn’t persist. With useRef: useRef returns a stable object that stays the same across renders.
Automatic DOM Binding: Without useRef: React doesn’t automatically set .current to the DOM element, so REF.current won’t reliably point to the button. With useRef: React sets REF.current to the DOM element, making it reliable for DOM access.
Re-rendering: Without useRef: The object isn’t stable, which can cause unnecessary re-renders. With useRef: useRef doesn’t trigger re-renders when .current changes, making it ideal for mutable data that shouldn’t affect rendering. In short: useRef is the correct way to create stable, persistent, and React-compatible references for DOM elements.
Summary Using useRef is essential for creating stable references in React, as it:
Creates an object that persists across renders, unlike manually creating { current: undefined }.
Integrates with React's ref system, making REF.current a reliable way to reference DOM elements.
Allows mutable values to persist without causing re-renders, which is ideal for non-stateful data that needs to persist, like the button element in this example.
In almost all cases where you need a reference in React, using useRef is the correct and reliable approach.
In my case I was able to fix it by removing the "editor.language.brackets": [], setting in settings.json in VS Code. If you also have such a setting, try to remove it.

Busbar Systems are essential for every power application that provides major interfaces between the outer world and the power modules. It has been witnessed throughout the design iterations in industrial cranes that occurred in recent years with the evolution of industries. Conducting sufficient amounts of currents in the applications, busbars are mandatory with a focus on electrical power distribution in cranes while meeting the dynamic application needs. In this blog, let's deep dive into everything about electrical bus bars, types, and their applications in detail.
What Are Busbars? An electrical busbar or a conductor bus bar, as the name suggests, defines a conductor or the aggregate of conductors that receive electric power from the incoming feeders, to further distribute it to outgoing feeders. Otherwise, an electrical bus bar is an electrical junction where the incoming and outgoing currents meet. The conductor busbar systems gathers electrical power in a centralized location.
DSL Busbars are made up of highly electrically conductive metals and they distribute & carry power from a source to a destination or multiple destinations. They are used in EOT Cranes to supply power from the grid to the crane control panel. The full Form of the DSL busbar is Down Shop Lead.
How Do Busbars Work? Busbars are usually used to connect electrical power sources and loads. It connects the generator and main transformer in power busbar systems and also interlinks the incoming/outgoing transmission lines. The busbar is visibly a copper or aluminium strip that transfers electricity in a substation, electrical apparatus, or switchboards. The flexible bus bars are made using aluminum tubes with disc insulator strings on either side and gantries to support them. While rigid busbars get support on post insulators and are made using Aluminum tubes. The size of the bus bars determines the amount of current it can carry safely. The common shapes are flat strips, hollow times, etc. since these shapes can allow more heat dissipation of the large ratio of surface area to cross-section area.
The Function of a Bus Bar A bus bar serves as an electrical connection point where it gathers electric power from incoming feeders and then disperses it to outgoing feeders. The primary function of a bus bar is to transport and distribute electricity, contributing to the efficiency of systems. In complex electrical setups, busbars can be a highly effective solution.
Nature of Busbar Connection Busbars could be supported in two ways: either on insulators or the insulation to surround them. A metal earthed enclosure busbar connector safeguards them against accidental contact. Neutral busbars also need insulation. Busbars could be also enclosed in the metal housing which uses bus-duct, isolated phase bus, or busway segregated phase bus. Connecting the busbars and the electrical apparatus needs welded connections or bolted clamps.
How Are Busbars Rated? Rated current- This is the RMS measure of current that busbars can conduct persistently with the rise in temperature within a particular limit.
Rated voltage- This is the RMS voltage value between lines for which you need the busbar
Rated frequency- The value of frequency for which the busbar systems work
Rated short-time current- The RMS current value that bus bars carry for specified temperature rises in a specified duration
Rated insulation level- the normal rated voltage, power frequency withstand voltage, switching impulse voltage or lightning impulse withstand voltage used to characterize the insulation levels.
Factors to Consider While Selecting Busbars You need to consider certain factors before choosing the busbar sizes—these include current carrying capacity, surface gradient, performance, etc. Electrical and mechanical stresses like short circuit fault currents should be considered to withstand thermal stresses. Also, the short circuit effects that cause stress to the clamps and connectors need to be well addressed. Let's check out the factors considered in selecting bars factors:
Ambient temperature Operating temperature Height from sea level Voltage level Short circuit current Type of bar coverage The number of busbars in each phase is considered. Types Of BusBar Arrangements in Power System Let’s now take a glance at the various types of busbar systems and learn more about them:
Single Busbar System This system arrangement consists of a main bus that remains energized every time and every circuit is connected to this. This arrangement offers the least amount of dependability. The complete loss of the substation can occur with the bus faults or any failure in the operation of the circuit breaker.
Advantages:
Cost-effective Needs small area Highly expandable Easy Concept and operation Great on protect

i found the answer: if i Explicitly define the value of "c", like this, it will update.
parent.children = [Child(a=123, b="b", c=None), ...]
but if i just use the defualt none value of "c", it will not update, the original value will remain unchanged.
parent.children = [Child(a=123, b="b"), ...]
Should I open an issue on github?
Yes; this was an oversight on our part, and now that you've raised the issue (thanks!) I've committed a simple fix that should make it into the next release ;)
Using Android Studio, the correct repo is at
so this old repo will display 404 error https://dl.google.com/dl/android/maven2/com/github/QuadFlask/colorpicker/0.0.15/colorpicker-0.0.15.pom
nor
https://repo.maven.apache.org/maven2/com/github/QuadFlask/colorpicker/0.0.15/colorpicker-0.0.15.pom
Therefore, it could not find the repo in these two locations.
You fix it by writing in build.gradle(Project level):
buildscript {
repositories {
google()
mavenCentral()
maven {
url "https://maven.scijava.org/content/repositories/public/"
}
}
dependencies {
.........
}
}
allprojects {
repositories {
google()
mavenCentral()
maven {
url "https://maven.scijava.org/content/repositories/public/"
}
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
Ensure in the build.gradle(App level):
dependencies
{
...........
implementation 'com.github.QuadFlask:colorpicker:0.0.15'
}
Sync project and it will show BUILD SUCCESSFUL.
Many people claim that asyncio should be used for I/O-intensive tasks. However, this might not actually be the case. I wrote a simple benchmark and observed that for I/O-intensive tasks, the performance of asyncio and multithreading is quite similar. In fact, I believe that asyncio might only be necessary when dealing with very complex state sharing and contention. Otherwise, if using asyncio significantly affects the coding style, it’s best to avoid it.
Room has a builder that created an in-memory database:
Room.inMemoryDatabaseBuilder(context, AppDatabase::class.java, DATABASE_NAME)
If you combine this with dependency injection (to build a singleton of the database instance) you'll get a robust and extensible solution.
If your loop is in a while loop, there is no need to make another one. You can't do infinite actions for an infinity amount of times. In other words, infinity * infinity is impossible.
Without any unexpected error if there are no crates installed.
Use:
cargo install --list | grep -E '^[a-z0-9_-]+ v[0-9.]+:$' | cut -f1 -d' ' | xargs cargo install
thank for the answer of Gord Thompson in github.
Sorry, I did a minimal demo for test, and I did not reproduce the same problem, but it does exist in the actual program, so it is probably caused by other parts of the program. I will do another experiment to confirm where the problem lies before asking questions.
i found this article https://www.cypress.io/blog/component-testing-next-js-with-cypress#customize-your-nextjs-testing-experience
works great but need to keep this disclaimer from cypress team in mind :)
Unfortunately, there’s no such thing as a free lunch—adding these extra items to every mount will affect performance and introduce global state elements outside the bounds of your component. It’s up to you to decide whether these trade-offs are worth it based on your use case.
Finally, thanks to @Jester, encoding was the problem.
(gdb) r $(python3 -c 'import sys; sys.stdout.buffer.write(b"\x41"*152 + b"\x70\xe3\xff\xff\xff\x7f")')
Solved the isssue.

I've a simple .NET Core Web API that processes large size documents (> 10 MB < 50 MB). Basically it reads a document from CRM like Salesforce processes it with Aspose and send the processed documents to multiple destinations like Salesforce, Email etc. Instead of using byte array I thought of using streams but my question is after I process the document I get an output stream and how can I send a single output stream to multiple systems in parallel? Since streams are single threaded do I need to clone the stream? Cloning will again cause memory issues right? How we can handle large size documents in a memory efficient way and yet I can send to multiple destinations in parallel.
No, because it's not calling them.
A very unsatisfying answer but worked. After finding this, I tried creating a new project and just transferred my source code and assets to the new one and it worked. Oh, and I guess the important part, I opted out of SSR during generation.
I have the same problem and I don't know where the error is because the code was working properly a month ago and now it doesn't work

If you're reading this in 2024 and still having issues even after implementing all the suggestions here, I just spent a ton of time trying to get to the bottom of this and managed to find a solution as my logs and Sentry were completely clogged.
Short answer: You need to update your nginx.conf file to rewrite the host if it's coming from a fixed IP.

Is song.image the full path of asset you have? If so, you should initialize UIImage first, and then pass UIImage into Image
e.g.
instead of
Image(song.image)
use
Image(uiImage: UIImage(named: song.image)!)
Check the documentation for Image and UIImage to see various ways of initializing each object

Simply using a directory that's not named src/ doesn't require any arguments, by default colcon will recursively search for packages in the current directory.
You can specify a specific directory with --base-paths and/or add an empty file named COLCON_IGNORE to your other directories that should be ignored.

you could always just use sprite collision.
Ensure that you are using a recent version of Git. Older versions of Git for Windows might have compatibility issues with curl. If you’re using an older version, consider updating Git manually by downloading the latest installer from the official site. If above solution is not working, uninstall Git for Windows from your system, restart, and then download and install the latest version.

Expo cloud compilation is the ugliest thing I have ever seen, it wipes out local compilation. Good job, brother. I support you, Trump.
I think the reason that you are unable to run the shell script through ./li.sh is because you haven't set the file permission to executable
You could have a look at this https://www.redhat.com/en/blog/linux-file-permissions-explained
tldr; you can run sudo chmod +x li.sh and then continue to proceed with ./li.sh
Assuming you are in the same directory when u run bash li.sh and ./li.sh , it should both work the same way. When you specify bash li.sh , it first runs bash and executes the file , where as when you run ./li.sh , it reads the file , sees that there is the #! symbol , it will run /bin/env bash , and then it will continue the script
I'm using process.cwd() but I'm getting this error on vercel

I also faced some difficulties in deploying fullstack application using react and nestjs with nginx. Here is my approach: enter image description here I used nginx as follows:
It is 2024. You might want to use UDP if you don't mind loosing packages on the way during transport. This is totally fine for audio or video (streaming) but not if you expect a proper response. Use inproc if you need to support windows and all or ipc if you support a proper platform such as linux/BSD.
We are using ipc to communicate between micro-services and it's blazing fast. If you need to distribute your services over multiple servers use TCP. It works great and fast.
