In general I question I lot the need for this and its usefulness, as short names are usually useful only in short blocks with 1/2 params, otherwise the readability of the code is impacted a lot. We already have a good shorthand for blocks with one param (at least in the most common case), so it feels to me we're complicated the parser/syntax without a very strong case for doing so. Many features are useful to some extent, but we should also keep in mind that none of them come for free.

Amazing Facts about Logo Design that Might Shock YouSushmachoudharyJan 7 · 4 min readGraphic Design is one of the best methods for getting your brand recognized all over the world. Many startups and businesses invest heavily in their graphic design to ensure that they get the best graphics.A single design has a potential of conveying unspoken words, which makes it one of the most prominent way that brand uses to market their business. Since, Logo design is an essential element of branding therefore, it becomes important to know the facts about logo design and the famous logos.Pepsi paid $1 Million for Getting a Golden Ratio LogoPepsi hired designers and spent an estimated amount of $1 million dollar in designing their logo. It took around 5 months time to redesign the icon. Pepsi spent several million dollars to change their custom logo design from billboard, vehicle wrap, and other advertising campaigns.The reason for changing Pepsi logo to match the golden ratio proportion is because golden ratio proportion is considered to be the most attractive and harmonious designs to look at.Nike Logo Swoosh is Actually an Goddess’s FeatherNike is named after the Goddess with the same name Nike. The goddess personified victory and often portrayed with wings. These wings became the inspiration for Nike, Inc. Nike logo is one the most recognized logos in the world with an estimated worth of $26 Billion alone.In 1983, the designer Carolyn Davidson, also known as “The Logo Lady” was gifted with a golden Swoosh ring with an embedded diamond and 500 shares (Worth $1,000,000 as of 2015) of Nike stock to express his gratitude.Starbucks Logo Takes Inspiration from Greek MythologyStarbuck logo represents a mermaid holding two tails. She was a siren in Greek mythology that lured the sailors. Alternatively, she was connected with European folktale Melusine, who married a human. The logo of Starbucks was changed throughout the years. The most recent version of the logo is more friendly and recognizableBaskin Robbins Has “31” Masked in their LogoBaskin Robbins is an ice cream and cake chain company having various branches throughout the world. The company began its operation in 1945 with 31 flavors of ice cream. You can find the number “31” concealed in their logo.Apple LogoThe Apple logo was created back in 1977 with analogous tools, therefore, needed an update. It took $50K to digitize the apple logo.McDonald's Logo Has a Hidden MeaningMcDonalds Logo does not just represent the word “M” but resembles female breasts. In 1962, the logo for McDonald's was re-designed. They hired a psychologist named Louis Cheskin who suggested them to use golden arcs making an “M” which would make them remind them of their childhood.BMW Logo Is Not a PropellerThe BMW logo is not a propeller it was popularly known for, but represents the flag of Bavaria.BMW LogoBavaria FlagTwitter LogoTwitter logo was bought for just $15 when the company was launched. The designers of the twitter logo, Simon Oxley received just $6 for selling the logo. Later, Twitter hired renowned designers to redesign the same bird logo.If you are a business and want to get your logo, organizing a graphic design contest is the best option.MGM Logo used 7 different LionsMGM logo uses 7 different lions for their iconic logo. The Lions were trained to roar on cue to get the right mascot logo.An image was circulated on the internet depicting the lion being ill treated for getting the right logo but, it's fake, the image was photoshopped and the lion was going through an MRI scan.

Due dates and threshold dates aren't part of the todo.txt format spec! Due date and threshold date are implemented as key:value tags, which are fully compliant with the todo.txt format spec. They both are popular extensions to the todo.txt command line scripts.

And since it’s just a client, you can always use the todo.txt format text file created by it in the very beginning with any other client. Give it a try.

Because moving tasks around is as easy as dragging a row to a new location, you can easily re-prioritize without jumping between views or clicking twelve times to get where you need to go.

And it requires way fewer clicks than most other options. And let's face it: Nobody has time for extra clicks—you just want to get work done, not manage the work you need to get done.

I have concluded that all these systems are cumbersome and onerous in some ways, more concerned with design than functionality, and more concerned with ease-of-use than speed and efficiency.

Why a rewrite? To finally have a clean split between GUI code and logic.

Simplicity is todo.txt's core value

Most to-do lists give you no control over your data. Your tasks live inside the app, not in a document you can edit, and syncing is handled by whichever company made the app. If you don't like this, todo.txt is a great alternative.

And I am planning on cutting back on my personal use of social media (easier said than done) and want to try to return to using my blog more than Twitter for sharing.

Types of questions and where to ask: How do I? -- ask on Server Fault (tell them what tags to use -- your product tag at minimum) I got this error, why? -- ask on Server Fault I got this error and I'm sure it's a bug -- report it on your own site I have an idea/request -- report it on your own site Why do you? -- ask in your own community (support forum, etc) When will you? -- ask in your own community

A 2009 study of Wikipedia found that most weasel words in it could be divided into three main categories:[13] Numerically vague expressions (for example, "some people", "experts", "many", "evidence suggests") Use of the passive voice to avoid specifying an authority (for example, "it is said") Adverbs that weaken (for example, "often", "probably")

Minimalistic design... The specification only requires a very small set of features to be implemented by clients and servers. tus embraces simplicity

Now using sudo to work around the root account is not only pointless, it's also dangerous: at first glance rsyncuser looks like an ordinary unprivileged account. But as I've already explained, it would be very easy for an attacker to gain full root access if he had already gained rsyncuser access. So essentially, you now have an additional root account that doesn't look like a root account at all, which is not a good thing.

For full disclosure, I wrote ssh-ident. Surprisingly, that still doesn't prevent me from liking it.

Before each election, I have traditionally written up an analysis of the California ballot measures and send it to my friends. It's not always obvious what the "real" agenda is on each one, and even with clear purposes there are often competing interests at play. These writings are the result of my own analysis, which comes from a libertarian perspective, and I'm not knowingly affiliated with any party behind any ballot measure. I believe that mere lists of "vote yes" or "vote no" are not very helpful except for sheep: it's important to know why one is urged to vote in any given direction. I would rather you vote against my position because you had an opposing view than vote with my position because you flipped a coin.

Applications like rsnapshot rotate a snapshot to the next level by creating a hard-linked copy. Creating a hard-linked copy may seem like a good idea but it is still a waste of disk space, since only files can be hard-linked and not directories. The duplicated directory structure can take up as much as 100 MB of space.

Unlike similar tools that are scheduled to take backups at a fixed time of the day, Timeshift is designed to run once every hour and take snapshots only when a snapshot is due. This is more suitable for desktop users who keep their laptops and desktops switched on for few hours daily. Scheduling snapshots at a fixed time on such users will result in missed backups since the system may not be running when the snapshot is scheduled to run. By running once every hour and creating snapshots when due, Timeshift ensures that backups are not missed.

Just for the record newer versions of ssh support the -W option, you can do something like ProxyCommand ssh -W %h:%p gateway instead of depending on nc

It doesn't use a database (unlike Keepass) and thus doesn't open all passwords at once. Just one at a time. Since it's just a directory of encrypted files, you can access your passwords with any PGP-compatible tool.

Remarkably, studies receiving mainly public funding can, a quarter of a century on, still survive without making their data available in a useful way. In the UK a series of studies—the Avon Longitudinal Study of Parents and Children (ALSPAC) (100), UK Biobank (101), and Born in Bradford (102), among others—have surely been exemplary in promoting data accessibility.

uBlock Origin blocks ads through its support of the Adblock Plus filter syntax. uBlock Origin extends the syntax and is designed to work with custom rules and filters.

I term all transcendental ideas, in so far as they relate to the absolute totality in the synthesis of phenomena, cosmical conceptions; partly on account of this unconditioned totality, on which the conception of the world-whole is based—a conception, which is itself an idea—partly because they relate solely to the synthesis of phenomena—the empirical synthesis; while, on the other hand, the absolute totality in the synthesis of the conditions of all possible things gives rise to an ideal of pure reason, which is quite distinct from the cosmical conception, although it stands in relation with it. Hence, as the paralogisms of pure reason laid the foundation for a dialectical psychology, the antinomy of pure reason will present us with the transcendental principles of a pretended pure (rational) cosmology—not, however, to declare it valid and to appropriate it, but—as the very term of a conflict of reason sufficiently indicates, to present it as an idea which cannot be reconciled with phenomena and experience.

'Then, thou must on similar grounds admit that unity and goodness are the same; for when the effects of things in their natural working differ not, their essence is one and the same.'

Oportet igitur idem esse unum atque bonum simili ratione concedas; eadem namque substantia est eorum quorum naturaliter non est diuersus effectus.

Once you have uttered "The Good," add no further thought: by any addition, and in proportion to that addition, you introduce a deficiency.

Secunda via est ex ratione causae efficientis. Invenimus enim in istis sensibilibus esse ordinem causarum efficientium, nec tamen invenitur, nec est possibile, quod aliquid sit causa efficiens sui ipsius; quia sic esset prius seipso, quod est impossibile. Non autem est possibile quod in causis efficientibus procedatur in infinitum. Quia in omnibus causis efficientibus ordinatis, primum est causa medii, et medium est causa ultimi, sive media sint plura sive unum tantum, remota autem causa, removetur effectus, ergo, si non fuerit primum in causis efficientibus, non erit ultimum nec medium. Sed si procedatur in infinitum in causis efficientibus, non erit prima causa efficiens, et sic non erit nec effectus ultimus, nec causae efficientes mediae, quod patet esse falsum. Ergo est necesse ponere aliquam causam efficientem primam, quam omnes Deum nominant.

In the world of sense we find there is an order of efficient causes. There is no case known (neither is it, indeed, possible) in which a thing is found to be the efficient cause of itself; for so it would be prior to itself, which is impossible. Now in efficient causes it is not possible to go on to infinity, because in all efficient causes following in order, the first is the cause of the intermediate cause, and the intermediate is the cause of the ultimate cause, whether the intermediate cause be several, or only one. Now to take away the cause is to take away the effect. Therefore, if there be no first cause among efficient causes, there will be no ultimate, nor any intermediate cause. But if in efficient causes it is possible to go on to infinity, there will be no first efficient cause, neither will there be an ultimate effect, nor any intermediate efficient causes; all of which is plainly false. Therefore it is necessary to admit a first efficient cause, to which everyone gives the name of God.

It allows the module code (and subsequently dependants on the module) to not use preprocessor hacks, source code changes, or runtime detection hacks to identify which code is appropriate when creating a client bound package.

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.

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).

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.

For most of the twentieth century, Census Bureau administrators resisted private-sector intrusion into data capture and processing operations, but beginning in the mid-1990s, the Census Bureau increasingly turned to outside vendors from the private sector for data captureand processing. Thisprivatization led to rapidly escalating costs, reduced productivity, near catastrophic failures of the 2000 and 2010 censuses, and high risks for the 2020 census.

const setRefs = useRef(new Map()).current; const { children } = props; return ( <div> {React.Children.map(children, child => { return React.cloneElement(child, { // v not innerRef ref: node => { console.log('imHere'); return !node ? setRefs.delete(child.key) : setRefs.set(child.key, node)

Epiphany aims to present the simplest interface possible for a browser. Simple does not necessarily mean less-powerful. The commonly-used browsers of today are too big, buggy, and bloated. Epiphany is a small browser designed for the web: not for mail, newsgroups, file management, instant messaging, or coffeemaking. The UNIX philosophy is to design small tools that do one thing and do it well.

you probably referred to the positive case where no one overrides anything and so the property returns true, so no need to process further because it is really an automation. Yes, this is true. I just hope that it does not make websites skip the checks if this returns false.

I should also add that I'm in favor of relying more heavily on integration testing. When you do this, you need to unit test fewer of your simple components and wind up only having to unit test edge cases for components (which can mock all they want).

Technology

Many of these metro areas are characterized by low densities and a separation of residential and business construction that forces homes out into the suburbs where transit is either spotty or non-existent. That makes cars necessary for even the most mundane trips.

The reason is a mix of topography and public policy.

Today, many regions have cheap gas, easy-come auto loans, Uber, Lyft, and now a new breed of bike- and scooter-share. So transit users aren’t riding like they used to.

Americans are getting even more into cars. More survey respondents said they had full-time car access today than did two years ago, 54 percent compared with 43 percent. Similarly, the number of respondents who said they didn’t have access to a car decreased, from 27 percent to 21 percent.

We’ll make sure that decisions that need to be made post-launch are informed by actual facts of user behavior, not just best guesses.

Using expect { }.not_to raise_error(SpecificErrorClass) risks false positives, as literally any other error would cause the expectation to pass, including those raised by Ruby (e.g. NoMethodError, NameError, and ArgumentError)

This is called a false positive. It means that we didn't get a test failure, but we should have

The more your tests resemble the way your software is used, the more confidence they can give you.

Most of the damaging features have to do with encouraging testing implementation details. Primarily, these are shallow rendering, APIs which allow selecting rendered elements by component constructors, and APIs which allow you to get and interact with component instances (and their state/properties) (most of enzyme's wrapper APIs allow this).

File-relative configuration Babel loads .babelrc (and .babelrc.js / .babelrc.cjs / package.json#babel) files by searching up the directory structure starting from the "filename" being compiled (limited by the caveats below). This can be powerful because it allows you to create independent configurations for subsections of a package. File-relative configurations are also merged over top of project-wide config values, making them potentially useful for specific overrides, though that can also be accomplished through "overrides".

“Code without tests is broken by design”

All conversations and communities on Spectrum agree to our underlying code of conduct. This code of conduct also applies to all conversations that happen within our contributor community here on GitHub. We expect discussions in issues and pull requests to stay positive, productive, and respectful. Remember: there are real people on the other side of that screen!

Rack middleware is more than "a way to filter a request and response" - it's an implementation of the pipeline design pattern for web servers using Rack. It very cleanly separates out the different stages of processing a request - separation of concerns being a key goal of all well designed software products.

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.

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.
