An ssh public key in a ~/.ssh/authorized_keys file can have a command="" option which forces a particular command to be executed when the key is used to authenticate an ssh connection. This is a security control that mitigates against private key compromise. This is great when you only need to execute a single command. But if you need to perform multiple tasks, you would normally need to create and install a separate key pair for each command, or just not bother making use of forced commands and allow the key to be used to execute any command.

Both /proc and /sys are virtual filesystems which reflect the state of the system, and allow you to change several runtime parameters (and sometimes do more dangerous things, like directly writing to the memory or to a device). You should never backup or restore them.

You might think that a one-line configuration file is not worth backing up. However, if it took you three hours to figure out how to set that configuration, it will probably take you three hours again in six months time.

I would rather you vote against my position because you had an opposing view than vote with my position because you flipped a coin.

Timeshift for Linux is an application that provides functionality similar to the System Restore feature in Windows and the Time Machine tool in Mac OS.

CloneZilla works perfectly. It produces small image files, has integrity check and works fast. If you want to use third device as image repository you should choose device-image when creating image of the first disk and then image-device when you restore it to second disk. If you want to use only two disks - you should use device-device mode. Optionally you may want generate new UUIDs, SSH-key (if SSH server installed), and change hostname.

This problem can also come up when you use npm link or an equivalent. In that case, your bundler might “see” two Reacts — one in application folder and one in your library folder. Assuming myapp and mylib are sibling folders, one possible fix is to run npm link ../myapp/node_modules/react from mylib. This should make the library use the application’s React copy.

Arguably, the rails-team's choice of raising ArgumentError instead of validation error is correct in the sense that we have full control over what options a user can select from a radio buttons group, or can select over a select field, so if a programmer happens to add a new radio button that has a typo for its value, then it is good to raise an error as it is an application error, and not a user error. However, for APIs, this will not work because we do not have any control anymore on what values get sent to the server.

When the controller creates the user, instead of adding a validation error to the record, it raises an exception. How to avoid this?

I really dislike the reasoning as stated in the issue listed above. Since the value is coming over the wire, it should be treated the same as a freetext input where the expectation is to validate in the model and not the controller. This is especially true in APIs where the developers have even less of a say as far as expected input coming from form data (for example).

In case anyone wants a hack, here is what I came up with.

But now the first line throws an exception ArgumentError: '0' is not a valid audience

By default, fetch() doesn’t provide a way to intercept requests, but it’s not hard to come up with a workaround. You can overwrite the global fetch method and define your own interceptor, like this

TC39 urges caution when using Stage 2-or below proposals, as it might result in inadvertent pressure from the community to keep the implementation as-is instead of improving it for fear of breaking existing code or ecosystem fragmentation (e.g. using a different symbol like # instead of @ for decorators).

It's completely understandable that this happens without realizing it, but continuing to do so sets different expectations for how the language progresses. It's nothing to feel guilty about — we learn as a community and remind one another of how JavaScript works.

Therefore, it's easy to search around for tweets/blog posts/talks that say "ES7 Decorators" and find that it's become the accustomed name for it.

Because immutable components also prevent their children from re-rendering, they should probably not have non-immutable children.

Null Components should never have children - they'd never be rendered.

Injector components should never be self-closing, and they should never wrap multiple children. We can fix this at code-time and not wait for the errors at runtime.

I started this project mainly to explore using a React Native app to build React Native apps. There is a lot missing... I had to abandon while it was in progress since I don't have as much free time any more.

Try doing the equivalent of #indexes without it. Not that it's especially hard, but you have to stop and work out a solutuon. When you need it, that's when you wish there were already a method for it.

Second, uBlock Origin does not have a dedicated server, it can't "phone home" with your browsing data, there is only GitHub, and GitHub is completely unrelated to uBlock Origin.

Reason compiles to JavaScript thanks to our partner project, BuckleScript, which compiles OCaml/Reason into readable JavaScript with smooth interop. Reason also compiles to fast, barebone assembly, thanks to OCaml itself.

Revery is like flutter in that it does not use native widgets.

Today, Electron is one of the most popular tools for building desktop apps - using an HTML, JS, CSS stack. However, it has a heavy footprint in terms of both RAM and CPU - essentially packing an entire browser into the app.

I'm considering this, although I'm still leaning towards not including it and I'd love to just get rid of first if it wouldn't break so many peoples tests. Newcomers to Capybara don't understand (or aren't willing to learn) the issues that all/first (and last if added) have and massively overuse them. Yes the fact that all and first now wait by default will prevent some of the new user issues/confusion, but it won't fix the non-reloadability issue.

It makes sense that the incoherent render would not be committed to browser and that it would not have any consequences most of the time. But that means that you render logic must be ready to manage incoherency between props and states without crashing. E.g. a list of resource ids in props that doesn't match a list of http requests from a previous id list in the state could lead to weird situations. This is a worry that didn't exist in class components.

Since an uncontrolled component keeps the source of truth in the DOM, it is sometimes easier to integrate React and non-React code when using uncontrolled components.

This does not set the native input element to indeterminate due to inconsistent behavior across browsers. However, we set a data-indeterminate attribute on the input.

the main reason we built a new multiprocess architecture is that Chromium's multiprocess support was never contributed to the WebKit project. It has always lived in the separate Chromium tree, making it pretty hard to use for non-Chrome purposes.Before we wrote a single line of what would become WebKit2 we directly asked Google folks if they would be willing to contribute their multiprocess support back to WebKit, so that we could build on it. They said no.

Can I ask people to upvote my submission? No. Users should vote for a story because they personally find it intellectually interesting, not because someone has content to promote.

The thing is that each UI decision depends on countless other UI decisions. A simple example is keybindings. On UNIX/Linux, it’s nearly impossible to pick reasonable default bindings for global desktop navigation because they all conflict with bindings that some app is using. On Windows, the desktop navigation bindings are hardcoded, and no app uses them, because apps know for sure which bindings to avoid.

REST and GraphQL are wonderful tools to create an API that is meant to be consumed by third parties. Facebook's API, for example, is consumed by ~200k third parties. It is no surprise that Facebook is using (and invented) GraphQL; a GraphQL API enables third parties to extensively access Facebook's social graph enabling them to build all kinds of applications. For an API with that many consumers, GraphQL is the fitting tool. But, to create an internal API (an API developed and consumed by code written by the same organization), RPC offers a simpler and more powerful alternative. Large companies, such as Netflix, Google and Facebook, are starting to replace REST/GraphQL with RPC for their internal APIs. Most notably with gRPC which is getting popular in the industry.

Some time ago I asked on Reddit: “What’s the consensus among the React community for testing React components?” Shawn Wang replied: “testing is an enormously complicated and nuanced topic on which there isn’t a consensus anywhere in JS, much less in React.” I was not trying to find the best library for testing React. Mainly because there isn’t one.

7-Eleven moves to support animal welfare By Nick Hall | 17 Feb 2019 View comments Global convenience chain, 7-Eleven has made major changes to its supplier sourcing agreement, eliminating caged eggs for the first time. The move follows ongoing criticism of the Australian cage egg farming industry, with several brands and chains making the early decision to move to wholly sustainable sourcing in-line with welfare standards. Working closely with suppliers across all states, 7-Eleven has now ensured that only free range eggs would be available for order by all stores. Clayton Ford, General Manager Corporate Affairs, 7-Eleven said the decision to phase out cage eggs was developed in accordance with franchisee wishes, with the convenience giant announcing it will increase support to assist in the transition. “Whilst our franchisees are free to engage with alternative suppliers due to our franchise agreement, we will continue to work alongside them to encourage their involvement in this initiative by sourcing free range eggs via our centralised supply chain,” Ford said. “We recognise that this is just one step, and we will continue to review animal welfare commitments in our supply chain and 7-Eleven branded products as opportunities arise.” Want to launch a convenience store of your own?

Let's make the example even easier. function convertDate<T extends string | undefined>(isoDate?: string): T { return undefined } 'undefined' is assignable to the constraint of type 'T' Means: What you return in the function (undefined), matches the constraints of your generic type parameter T (extends string | undefined). , but 'T' could be instantiated with a different subtype of constraint 'string | undefined'. Means: TypeScript does not consider that as safe. What if you defined your function like this at compile time: // expects string return type according to generics // but you return undefined in function body const res = convertDate<string>("2019-08-16T16:48:33Z") Then according to your signature, you expect the return type to be string. But at runtime that is not the case! This discrepancy that T can be instantiated with a different subtype (here string) than you return in the function (undefined) is expressed with the TypeScript error.

There are many strings which I need to convert if not undefined. I could do as follows: { date1: date1 ? formatISODate(date1) : undefined, date2: date2 ? formatISODate(date2) : undefined ...

Both of the below are valid as far as T extends (...args: any[]) => any goes logFn((a, b) => a + b) logFn((a, b, c) => c) But if you refer back to the example I gave, the inner definition as: return (a, b) => fn(a, b); So option 2. will throw an error here, which is why typescript is warning you about it.

In the body of the function you have no control over the instantiation by the calling context, so we have to treat things of type T as opaque boxes and say you can't assign to it. A common mistake or misunderstanding was to constraint a type parameter and then assign to its constraint, for example: function f<T extends boolean>(x: T) { x = true; } f<false>(false); This is still incorrect because the constraint only restricts the upper bound, it does not tell you how precise T may really be.

P can't be assigned {}, since the Generic Type P can be a more defined (or restricted) type.

Unfortunately, numerous widely-used tagless-final interfaces (like Sync, Async, LiftIO, Concurrent, Effect, and ConcurrentEffect) encourage you to code to an implementation.

Try to avoid mucking with native prototypes, including Array.prototype, if you don't know who will be consuming your code (3rd parties, coworkers, yourself at a later date, etc.). There are ways to safely extend prototypes (but not in all browsers) and there are ways to safely consume objects created from extended prototypes, but a better rule of thumb is to follow the Principle of Least Surprise and avoid these practices altogether.

However, if more control is needed, you can pass any of these pieces of state as a prop (as indicated above) and that state becomes controlled. As soon as this.props[statePropKey] !== undefined, internally, downshift will determine its state based on your prop's value rather than its own internal state.

refKey: if you're rendering a composite component, that component will need to accept a prop which it forwards to the root DOM element. Commonly, folks call this innerRef. So you'd call: getRootProps({refKey: 'innerRef'}) and your composite component would forward like: <div ref={props.innerRef} />
