Java downloading a file remotely via scp

The following Connectors are available for use within Gluon CloudLink. If you have a specific requirement for a custom Connector, please let us know. This is the most generic connector and allows synchronization data to any enterprise or cloud system that can talk REST.

This connector invokes a remote function that is defined in your CloudLink application. This connector specifically synchronizes data from and to your Couchbase server. Ideally suited if you have an existing Couchbase installation that you want to unlock to mobile devices.

Each of them should be implemented on the back end application to be able to handle the request. JSON payload of the new object. If the object is a String , the payload will use a key named v.

A new object is added to Gluon CloudLink. The objectIdentifier is the identifier that is passed in from the application client when retrieving or storing the object. An existing object is updated in Gluon CloudLink. An existing object is removed from Gluon CloudLink. A new object is added to a list.

The objectIdentifier is an identifier that is assigned to the object specific to Gluon CloudLink, i. This is in contrast to the listIdentifier , which is the identifier that is passed in from the application client when retrieving the list. An existing object in the list is updated.

An existing object is removed from a list. When a client application requests an object or a list that is not yet known inside Gluon CloudLink, Gluon CloudLink calls one of the following two endpoints on the back end application to retrieve the initial object or list information. A new object is being requested from the client application with the specified objectIdentifier. JSON payload of the list to retrieve. A new list is being requested from the client application with the specified listIdentifier.

When a client application requests data to be added, updated or removed from Gluon CloudLink, those requests will be provided with the remote function invocation as a JSON string. The Couchbase Connector is able to send data to an existing Couchbase Server. When activating the Couchbase Connector inside the Dashboard, you will need to provide the following information to let Gluon CloudLink be able to setup a connection with the Couchbase Server:.

You can specify more than one node, by separating them with a semicolon. An example of such an object can be seen below:. For each object in the list, the document will contain a key that matches the identifier of the object. Below is an example of a list that contains two objects:. The format of the documents stored inside the Couchbase bucket must also follow the same format as described in the previous section. Almost all mobile applications that exist today interact with a back end infrastructure for managing their data.

In theory, an application can directly make requests to these back ends, but there are a number of drawbacks for doing this:. Mobile devices are not always connected to the internet. It takes lots of boilerplate code to check connectivity and handle rescheduling of requests when connectivity is restored. Applications on mobile devices have specific lifecycles and need to behave according to specific policies. Some resources are conditionally available. The battery might be low, the application might be running in the background, the device is connected with a paid cellular network, etc.

Depending on those conditions, an application must behave differently. Mobile devices have less resources than the regular server, and those resources need to shared with other applications.

CloudLink provides Remote Functions to give the application a reliable and secure way for linking with existing back end systems. Each remote function is uniquely identified by a name.

This name will be used in the client application when it makes a call to the defined remote function. You will find the following sections:. Authentication: in here different authentication schemes can be created that are used when authentication is required by a remote function. A dialog will be shown where the following components can be configured:.

The function name is a unique identifier for the remote function. The name is used in the client application when a call needs to be triggered to the remote function. Mock responses can be enabled for testing purposes.

When mocking is enabled, a call to the remote function will not create a request to the actual configured endpoint, but respond directly with the data that is defined for the mock response.

The method defines what HTTP method to use when creating the request. Specify the timeout, in milliseconds, for reading from the remote function endpoint. If the value is zero, the default timeout will be used. Specify the timeout, in milliseconds, for connecting to the remote function endpoint. Specifies the authentication method that must be used when executing the request to the remote function. The authentication method can be selected from a list of authentication methods that are configured in the Authentication section.

The body type defines what kind of data will be sent to the remote function. The following types are supported:. When the raw body type is chosen, two extra fields will be available to specify the data and the media type of the raw body content. If caching is enabled, CloudLink caches each successful response from invocations to the remote function for one hour.

In closer detail, two HTTP response headers are currently inspected:. ETag: if an entity tag is provided, it will be used in any subsequent request to the configured endpoint for cache validation. Cache-Control: if cache control contains the words private or no-store , the response is not cached. If it contains public default value or a max-age value, the response is cached for the specified duration. Navigate to the Credentials section in Gluon Dashboard and choose the Customer tab.

Enter the required information. An optional specific version of the AWS Lambda function that must be executed. An optional payload that should be sent along when executing the AWS Lambda function.

When the selected payload type is string or byte array , you can specify the variable name of the payload. When the payload type is string , the value mapped with the key will be the JSON value that is loaded from the Payload string that can be specified in the text area below. If the payload type is byte array , then the JSON value will be a Base64 encoded string of the passed in array of bytes.

When the string payload type is chosen, an extra text area will be available to specify the data for the string content. The resulting data string must be valid JSON. If this is not the case, the request to the remote function will be aborted with a Bad Request status.

Defines the expected media type of the response from the AWS Lambda function. Configure a remote function that can invoke a Microsoft Azure function with an http trigger. A dialog will be shown in which the following components can be configured:. Define the Function Key to use for authorizing the invocation to the Azure function.

The key is passed down to the function using the x-functions-key HTTP header. Make sure that you copy the value of the Function Key and not its name. Azure functions using Anonymous authorization can leave this field empty. These are remote functions that are configured to run on the Fn Project platform.

Your Fn function must be available from a public registry on Docker Hub. The name of the docker image as it has been pushed to Docker Hub. When input is enabled, two extra fields will be available to specify the data and the media type of the input. The content of the text area will be passed down to the Fn Function during invocation. Specify the timeout, in seconds, for executing the remote function on the Fn Project platform.

Gluon Functions allow you to run Java functions inside a serverless platform that is managed by Gluon CloudLink itself. All you need is a zip file that bundles all the runtime jar files that are needed for running the function.

The entrypoint defines what method should be invoked when the Gluon Function is triggered. The syntax consists of the fully qualified class name and the method name to be invoked, separated with a double colon, i. Specify the Java Runtime environment that must be used for running the Gluon Function. You can choose between Java 8 and Java 9. Define the maximum amount of memory that should be provided when running the Gluon Function.

The bundle contains the actual classes that are needed for executing the Gluon Function. The bundle is a zip file containing one or more jar files that will be added to the classpath of the Gluon Function. Each remote function can be configured with additional parameters. Each parameter consists of a type, a name and optional default and test values. The name is used by the client application to define the value for the parameter that will be passed on when building the request for the remote function.

In the image below, a query parameter is configured with the name tagged. A query parameter will be sent as part of the query string. The query string is the part of the URI that comes after the question mark. A form parameter can be chosen for remote functions that are configured with the POST method. Form parameters are sent as form url encoded parameters in the body of the request. A header parameter can be used to send custom HTTP request headers when building the request for the remote function.

Variable parameters can be used to add custom variables to certain fields of a remote function. The variable will be replaced with the value that was passed on by the client application, before the actual request is executed. The endpoint of a remote function sometimes requires that the request is authenticated. The Authentication section provides three different authentication mechanisms that can be used together with a remote function.

The username and password are both required. See the OAuth 1. A token key and secret can be provided as well when necessary, but can be left empty if the endpoint only requires that the request must be signed with consumer credentials. This authentication method will apply the Resource Owner Password Credentials authorization grant as defined in the OAuth 2. When making a request to the defined endpoint of the remote function, it will first try to get an access token using the configuration details of the authentication method.

The access token will then be passed along with the actual request to the endpoint of the remote function. Each remote function can be tested from within Gluon Dashboard to ensure the configuration is valid.

Each configured parameter has an optional test value that will be used when testing the remote function. When no test value is provided, the default value will be used instead. When testing the remote function, the response of the endpoint will be printed so it can be verified against the expected value.

Useful information from each call that is being invoked by a remote function is stored in the Call Log and can be accessed in Gluon Dashboard.

Each request records the response code, the request and response timestamps and the body of the request and response. The body is capped at 8k. For calling a remote function from the client application we use the RemoteFunctionBuilder.

The RemoteFunctionBuilder can generate three different implementations of a RemoteFunction , each handling the response of the call to the remote function in their own way:. RemoteFunctionList: the response is converted into a list of objects, contained in a GluonObservableList.

RemoteFunctionChunkedList: the response of the function is a continuous stream of chunks, where each chunk is converted and added to a GluonObservableList. To start calling remote functions, we first need to build an instance by using the RemoteFunctionBuilder builder class. Each built RemoteFunction instance can then be triggered by calling the call method.

Every response that is returned by a call to a remote function will by default be cached locally in the private storage of the device. The next time the remote function is called, it will first load and return the cached data before making the actual call to the remote function in Gluon CloudLink.

This allows the application to already present the user with data from the last time the remote function was called. When the response from the call to the actual remote function in Gluon CloudLink is completed, it will overwrite the cached data with the data from the new response. By default, Gluon CloudLink will close the call to the endpoint that is configured for a remote function after 60 seconds. However, the connection will be kept open when the remote function uses chunked transfer encoding.

This is handled automatically, when the remote function specifies the Transfer-Encoding response header with the value chunked in its response.

In other words, there is nothing special that needs to be configured in your Remote Function definition on Gluon Dashboard. At the client side, you do need to use a different implementation of RemoteFunction that is able to handle chunked encoding: RemoteFunctionChunkedList.

Writing binary data with a remote function can be done by defining the remote function in Gluon Dashboard with the raw body type. In the client application, a byte array is provided as the raw body when building the remote function.

You can find end to end guides on working with different cloud servers with Gluon Cloudlink below:. Create Remote Functions using Microsoft Azure. The User Management service enables user authentication in your Gluon Mobile application.

It supports email and password based authentication and signing in with most popular identity providers like Facebook, Google and more. Enabling the login methods that should be available for your application can be done from the Gluon Dashboard. Navigate to the User Management link, and select the Login Methods tab. From here you can add and configure one or more login methods.

The login methods for identity providers all need a key and a secret from an application that is created on the respective identity provider. We provide a step-by-step guide to creating and configuring an application for each of the supported identity providers. The UserClient class is the access point to the User Management service.

It contains various methods for managing the authentication process. When a new instance is constructed, it will load the Login Methods that are enabled for the Gluon Mobile application and present them to the user when the authentication process is started.

When no authenticated user exists yet, the authentication process will be started. This is handled by taking the user to the implementation of the AuthenticationView. The default AuthenticationView implementation looks like this:. The user can select one of the presented login methods which will start the authentication flow for the selected login method. When a user was successfully authenticated, or when an authenticated user was already present, the provided consumer in the authenticate method will be called, passing in the authenticated user.

In case the user aborted the authentication process or when an unexpected error occurred, you can use the authenticate variant which takes an extra failure consumer. Once a user is successfully authenticated, that user will not need to authenticate again the next time the application is started.

To be able to restart the authentication process , you will first need to call the signOut method. The authenticated user can be retrieved from the UserClient by calling the getAuthenticatedUser method.

This returns an instance of User that has the following fields available:. As mentioned in the Data Storage section, you can also use a UserClient to make sure that only authenticated users have access to data that is loaded by a DataClient. To enable this, you need to pass in an instance of UserClient when building the DataClient:.

The first time that DataClient instance is used to access data, the authentication process will be initiated when an authenticated user was not yet present on the provided UserClient instance.

The Media Management service is a central place to manage media resources that are used inside your mobile application. We distinguish the following different media types:. Each media resource is defined by a unique name. The client application will request the media resource by specifying that name. Each media is further made up of one or more media variants. The variant contains the actual media file, together with metadata to define for which platform the media should be made available.

That way, it is for instance possible to define a different version of a media resource for Android and iOS.

From the Gluon Dashboard , selecting the Media Management link will present you with a view that is divided into two grids. The top grid holds the media, while the bottom grid will show the media variants that are linked with the selected media from the top grid. Add a new media resource by clicking the plus button from the top grid. This will create the media container as well as the first associated media variant. The following fields can be defined in the form dialog:.

This defines the unique name for the media resource. The client application will use this name to get a reference to the media resource. Associates the media variant with a specific platform.

When the client application requests a media resource and a specific variant exists that matches the platform where the application is running at, that media variant will be returned. You can further specialize the media variant by defining a matching platform version. This media resource will only be returned when both the platform and the version of the platform where the application is running on match with the specified values.

This is the ultimate resource file that is linked with the media variant. The MediaClient is the class that you need to load media resources on the mobile application. You only need to know the name of the media resource to load and call one of the two available functions:.

Resource Bundles are the standard way for providing i18n functionality in Java. Resources bundles are typically provided by one properties file or class for each supported language. These properties files or classes are then shipped together with your application package. With Gluon CloudLink we add the possibility to provide the resource bundles as an internet resource. The resource bundle consists of a resource file for each supported locale.

When adding a new resource bundle, you specify the locale that defines the associated language, country, script, etc. When the client application requests the resource bundle, it also passes down a locale so that Gluon CloudLink can return the resource bundle that matches the given locale. Resource Bundles can be uploaded from the Gluon Dashboard. Navigate to Media Management and choose the Resource Bundles tab.

The resource bundles are grouped by their bundle name. The most common scenario is to create a resource bundle for each view in your mobile application. Note: it is best practice to always provide a version of the resource bundle with an empty locale. This way, when no matching resource bundle could be found for a given locale, the resource bundle with the empty locale will be used as a fallback. You can use the returned Resource Bundle to load it into your View.

The Usage Analytics service is responsible for gathering statistics on the devices that are running your Gluon Mobile application. That information can then be visualised and analysed from within the Gluon Dashboard web application. The data that is being gathered contains information about the requests that the Gluon Mobile application makes to the Gluon CloudLink services. It also contains general information about the device itself, like the platform, the model, the version of the application, etc.

To enable usage analytics in your Gluon Mobile application, you will need to call the enable method on the UsageClient. The method can be called at any time, but ideally it should be called as soon as the application is launched. This will trigger a call to the Gluon CloudLink Usage service that stores the general device information. The trigger will only be sent the first time, so any subsequent calls to the enable method will do nothing.

The Gluon Dashboard can be used to inspect the usage information that is being logged by the devices that are running your Gluon Mobile application. When the UsageClient is enabled as shown in the previous section, there is nothing else to configure in the Gluon Dashboard. By default, the data that is shown is gathered from the devices that were active during the past two weeks. The Push Notifications service enables sending push notifications to the devices that installed your Gluon Mobile application.

A push notification is a notification message that can be sent to the device, even when the application is not running. This can be used to unobtrusively notify a user that an application specific event has triggered. Sign in to the Firebase Console with your Google Account and create a new project, or choose one of your existing projects to enable FCM for that project. The next step will allow enabling Google Analytics, which is optional. Press continue and wait until the project has been created.

Fill in the package name of the android application. The package name should match the name of the package that is configured in Android Manifest of your Gluon Mobile application. Select the settings icon to the right of Project Overview , and choose the Cloud Messaging service. Browse to the Gluon Dashboard , select the Push Notifications link and navigate to the Configuration tab. There are two main steps required to enable push notifications on iOS devices: First, get a valid p12 certificate, that will be required by the Dashboard, and second, get a valid provisioning profile to sign the app that will receive the notifications.

In both cases you need a valid account in the Apple Developer portal. More information about iOS notifications can be found here. Go to the Apple Developer portal , sign in with your credentials, and create a certificate for your app following these steps:. Click on it, and at the end of the expanded info click on the Edit button. Go to the Push Notifications section and click on Create Certificate for develpment, production or both.

Once Keychain Access shows the certificate, expand it, select it and your name, and right click, selecting Export 2 items , and save the file on your disk, i. Important note: This file and the password will be required later on the push notifications configuration tab of the Gluon Dashboard. Select the certificates you wish to include in this provisioning profile, and press Continue. These will be used later iosSignIdentity.

Build and sign your application using this profile. See iOS configuration. With the proper certificates, the Push Notifications tab can be used to send a push notification.

The checkbox labelled invisible can be selected to send silent push notifications to the user, without a visible notification. The Runtime Args service will be able to process it and execute certain action. The device token to use as the target for the push notification. The name of the topic to use as the target for the push notification.

To activate push notifications on your Gluon Mobile application, you will need a reference to the PushClient and call the enable method. This will trigger a message on an iOS device asking the user to confirm that push notifications are allowed for the application. For Android, we need to add the google-services. First make sure to configure your app so it can use Push notifications in the Apple Developer Center. You can follow this step-by-step guide.

When deploying to your iOS device, the provisioning profile will be downloaded. Note that this provisioning profile contains the entitlements that match those installed within the app, required to enable push notifications. The apsEnvironment property needs to match the match the used environment development or production. Gluon also has curated a list of samples to help you get started with our products.

These samples include everything including mobile, native images, cloudlink etc. We walk through the process of creation of each of these samples to make it easier for you to work with them.

Once we have done the FTP work, we should close the connection for security reasons.

If you need some additional help, once you are connected to the FTP server, type 'help' and this will show you all the available FTP commands.

There was never any free and forced upgrade to Windows 8, I assume you mean Windows 10? You may be right, perhaps it was Windows 8 to Windows But even in the days of XP, upgrade nags were already in effect, and one keypress or mouse click at the wrong time when the popup appeared could send you down that road.

Unless you already anticipated it ahead of time from past experiences and went through the settings and disabled automatic update checking. The overall intent and attitude matters more to me than the details, and the general intent of Microsoft and Apple, and Gnome, and Ubuntu, and many others seems to be "we know how your desktop should look and operate better than you do.

I went to Windows. Pinned snippingtool. My snipping tool again works, and exactly how I need it to. I upgraded to Windows 11 and the volume bar simply does not show when left clicking on the sound icon on the lower right of the task bar.

Well volume ain't that bad — I can't open widows defender after the update. It just acts like the app was unistalled and tells me that.

LTSC is only in windows enterprise, but what any windows pro user should use if they want to avoid the bleeding edge is switch to CBB, which is generally a lot more stable than the consumer releases of windows which effectively are public betas during their first few months.

Individual consumer users can't just purchase it on their own. Ignoring the licensing issues, LTSC failed for me. Just literally wouldn't boot one day. It's probably something hardware related, but the Pro version works great so far, even if it ignores update time and sticks my files into a black hole because it thinks it's a virus.

Hopefully the last version I'll use on bare metal as I move away from soldered processors and more centralized garbage. I've got some sympathy for this perspective. It's frustrating when you update in order to get the latest security updates - and you get forced to do a bunch of pointless busywork because some asshole has made some arbitrary change like deciding that 'which' is deprecated now.

Taywee 16 days ago parent next [—]. I kind of hate that this is going to live on as some example when the actual event was somebody proposing it, it failing in some builds on testing, and then a vote deciding against it. It was an example of good project governing preventing breakage, but for some reason it's already being remembered as the opposite. The Technical Committee had to step in and vote, so in that sense the last resort worked.

But a good migration is a quiet migration. When internal Debian discussions reach the user's stderr and causes builds to fail, the system has failed. There's only two ways to remember this sort of kerfuffle. Not at all, or as a lesson in deprecating things smoothly. Taywee 16 days ago root parent next [—]. Didn't that only happen in testing?

On January 22 we will forcibly update your instances to We hope you noticed this alert. I think they email account owner, because in our case he forwarded it to tech team. So if he would have chosen to not forward it to us, then we could have been in the same situation as you.

Just wanted to mention that they actually sent an email about that issue. At least to somebody :D We did our upgrades few months back 9.

Just finding out correct upgrade path with Postgis took some investigation, but overall the upgrade documentation was good. Waterluvian 16 days ago root parent next [—].

I didn't get an email. It was very alarming to discover and makes me anxious about what other forced upgrades I'll miss. I appreciate the point of this, but I think forcing upgrades is absolutely the wrong way to do it. Scream at me all you want, but don't force my stack to mutate and potentially break services.

Easy to blame AWS, but as the post you linked said, Postgres 9. What do you want AWS to do here? Keep running software that won't get security updates? That seems a bit wild to me. Communication could have been better, but there is no universe in which a managed database provider should be expected to continue to maintain instances with discontinued versions of software. Why were you still running 9. PostgreSQL is open source, so they could keep patching the old version with security fixes.

They are providing easier maintenance and monitoring for open source DBs. I'm not saying RDS couldn't be better, but I wouldn't expect them to maintain unsupported versions of 3rd party software. I agree AWS should be contributing back to the open source projects and they are listed as a 'sponsor' though not a major one on the Postgres website. The only way I could see this working would be if AWS charged the holdouts the cost of keeping them supported.

However, performing RDS Postgres upgrades is relatively quick and painless process. If a company doesn't have the capacity to do that every five years, then it shouldn't be running its own infrastructure.

That actually sounds like a great idea. They could charge more for use of older versions, so that people could calculate their tradeoffs, and migrate when they decide themselves. At some point the alternatives are force-updating your DB or shutting it down. One of those at least has a chance of keeping your service online. I agree the lack of communication is pretty bad though. The lesson here is to use proper hosting instead of AWS or some other fart cloud.

What I always say about this kind of thing is not "It's ok now because they un-did it. They will try something else again, and may in fact already be failing to work to my advantage right now in ways I just can't see. Once you know that, I prefer to just live without whatever the awesome thing is, somehow I will survive.

Negitivefrags 16 days ago root parent next [—]. This is one of the attitudes that makes the internet so toxic IMHO. Right up there with removing all nuance from a discussion and attacking a strawman It's a sign of docker desperately trying to find out a way to make money and survive. Not my problem, and not a valid problem in the first place, and not the charge against them. There are an infinite number of ways to make enough money to survive. You can sell your work honestly without artificially witholding work that is already done so you can sell it a million times over, and get people to do it by artificially creating or at least artificially preserving a pain point and randsoming the salve.

That is not simply doing work and paying for that work. If a thing is at all useful enough that anyone even wants to use it, then there are a million businesses that would love to pay you for expert installation and training and support of perfectly free software.

Ahh but that doesn't scale. You can sell your time to a few people and live very very well, but you can't sell your time to a billion people. No one is "trying to survive" in this story. What a strange and incredible thing to even try to say. It's almost like they probably should have figured out something so important by now.

I guess they didn't have a plan B after they didn't get bought out. Sucks to suck. That is exactly what I said. ByteJockey 16 days ago root parent prev next [—]. Dealing with a normal mistake isn't a problem because I can just opt out.

They removed that ability here. Now everyone is on 4. Welcome to Docker, I love you. Most of my experience with Docker Desktop is on a Mac behind a corporate proxy. I swear with every update they either removed my proxy settings or changed the behavior of how docker build and docker runtime inherited the proxy settings.

It was maddening because inevitably everyone on the team had different versions and therefore different behaviors. Took away the whole point of having a common tooling container. I upgraded my Ubuntu distribution last week and my old Xerox Phaser laser printer stopped working over the network. Something like this should never happen. I hate spending my weekends troubleshooting the Samba configuration.

Maybe I will connect the printer to a Windows VM. I noticed my wifi router had an "update firmware" option. Hmm, I said, that sounds cool.

Some issues I've encountered: 1 system lost its default route after an upgrade 2 network interface names changed, all connectivity was lost 3 system became unbootable UEFI boot order changed. This was all on a physical machine, and loss of connectivity meant having to to go the console. Sorry, newest Windows also has printing broken. No luck there.

Browsing a handful of reputable text-based websites from behind a NAT, I don't see the problem. I really appreciate people like you reminding most everyone that new! I live in Japan which people usually mock for still using fax machines, or keeping "the old ways" in many aspect of society. There are important positive things that people don't realize are lost as we "modernize" society.

For example, these days the TV spies on my usage and sends that data back to the maker company; they will then sell it to advertisers. Every update is aggressively pushed to me, and after i accept it, i notice more ads rebranded "you may enjoy" or "now trending" on the home screen.

Another example would be how awesome paper is. It displays information without requiring an energy source. It can be folded and unfolded. Have you considered getting rid of that TV and TV in general?

This works at small scale read: a small startup or for your own machine. It begins to fall apart once you have dozens of services each deployed at some time in the past 5 years, and no clue whether any of them are safe to update, or even validate.

Yeah, anything at scale I build with a bare minimum toolkit, and only use conservative tools in the process. By conservative, I mean something which would still work today if I wrote a script for it 10 or 20 years go. How do you make sure these are the reputable websites and not some interceptor, when using plaintext protocol? Do you have any actual arguments to back up your opinion? Add to that that desktop OSs are quite lacking when it comes to sandboxes, so even with browser sandboxes, the potential for serious damage is quire big.

So, staying ahead of bugs is a must. It's impossible to stay ahead of the bugs, because they appear ahead of the patches, and there are undoubtedly many unpatched bugs out there. But if I only visit sites where this is unlikely and don't allow JavaScript, which you seem to have missed I am much safer than when browsing willy-nilly with the latest patches.

Browsing the web with JS disabled on an up-to-date browser is still much safer. But you do you. It's safer if it is an option. AzzieElbab 16 days ago prev next [—]. Never updating and always updating are just two different ways of sticking your head in the sand. Igelau 16 days ago parent next [—].

The user would hold it with a weight and get the CPU to make heat that way. The small fix broke his experience. There are many other examples of this. Breaking compatibility by fixing bugs people rely on for instance. Any change can break something for a user downstream.

It's a very subjective evaluation for the producer to imagine potential impact to their consumers. It's easier if the relationship is rich and exclusive. In open-source where people do it on their free time and have thousands of consumers with widely different interests, it's pretty much impossible to label the release in a way that's conveying the right message to every user.

Semver, the way i see it, is just a way for the producer to subjectively label the amplitude of changes. The consumer should then ideally be familiar with the producer and get a sense of how they work and what they perceive as big. Still at the end of the day it's a very subjective judgment call system that doesn't offer real guarantees to consumers. If your software needs to be stable, don't upgrade, or spend time to review the changes in the dependencies. The version numbers are no guaranty.

There was an old story about a multiuser OS where the user would hold down a key to get more cpu slice during compiles… but my Google fu is failing to find it. The idea was that the OS gave more cycles to interactive sessions … something like that. It may be apocryphal.
