Cell phones are ubiquitous, and tend to be important if not necessary to own. Yet sometimes the cost of owning and using a mobile phone can get out of hand. And the prevalence of daunting cell phone bills only grows as more and more apps and functions that use data come into popular use.

The high cost of mobile data is a familiar problem for many; too many of us have run up against exorbitant bills after underestimating just how much data we have been using. And, for those with restricted monthly data allowances, exhausting the monthly supply of data can be irritating or even crippling for those who often depend on data.

10 Ways to Cure Your Mobile Phone Bill

Global mobile traffic now represents roughly 60 percent of internet traffic, making mobile apps a must-have for businesses. But consumers today increasingly expect an Amazon-like experience online. Small businesses do not just need to build a mobile app, they need to build a great one.

So much of success is knowing when to stay the course, even when you’re met with rejection after rejection.

30-year-old Melanie Perkins has been launching creative businesses since she was a teenager. Her first venture, designing and selling handmade scarves to sell in her hometown of Perth, Australia, was launched when she was just 14.  

At the age of 22, Perkins founded her next company, an online system for schools to design their yearbooks called Fusion Books. Today, Fusion Books is the largest yearbook publisher in Australia and has a presence in France and New Zealand.

The business terrain is one that changes much faster than most -- basically because the way business is done evolves based on cultural changes, changes in technology and even generational changes. It is safe to say that at all times, at least one of these things is changing.

We are in the era of giving back and social impact. Businesses should face this, and stop using the fact that they are not yet big businesses as an excuse for boycotting charitable involvements or social responsibility. Businesses that do this are missing out on the great benefits hidden on the other side of socially responsible companies.

Web accessibility may not be the first thing you think of when designing a website for your small business, but in the long run, few things could prove more important. Just like how a brick-and-mortar store must comply with ADA guidelines to ensure that all individuals can access their facilities regardless of whether they have a disability, business owners, as well as web design and digital agencies, must also ensure that those with disabilities have equal access to web content. Failure to make web accessibility a priority when designing your website could have significant long-term consequences.

When it comes to turning business challenges into opportunities, small business owners are quick, nimble, and creative. With state governments around the country shuttering all non-essential businesses to combat COVID-19 still in full swing, this is truer than ever.

But, unlike years past, where such an unprecedented closure would have put many small businesses out of business permanently, today they’re turning to mobility and connectivity in large numbers to keep their doors open—if only virtually.

Work in clojure for any length of time, and you must get used to the idea that data structures are immutable. For programmers coming from imperative languages this can be jarring, (no loop counters? recursion? wtf?) but after a while, you start to get it, then you start to like it, then you start to rely on it - or at least I have.

To such an extent that it's jarring not to have them. After a recent javascript coding session, I tweeted: "clojure's immutability has forever spoiled me - destructive operations in other langs feel like bugs now."

This prompted Joshua Kerevsky to ask me via email to elaborate, as he has been talking about safety in programming lately. This is a revision of my answer...

Clojure¹ is safer (in this sense) because there are never any side-effects when working with data. Languages with side-effects on data (i.e. pretty much every other language I've used) require the programmer to keep a mental model of application state and/or adopt defensive programming styles to avoid bugs caused by them.

The idea is illustrated by these two examples (I used chrome console and the leiningen repl to run them):

javascript:

clojure:

Javascript arrays are mostly (but not always) manipulated via destructive operations such as sort(), while in clojure, the js array's closest analogue (a vector) is never changed by functions that consume it. It's this "mostly" vs "never" distinction that gives rise to a paranoid feeling that I might be breaking things if I forget something in javascript. I also need to learn more "tricks" to get things to work as I expect. To get the javascript version to behave like the clojure one, we must explicitly copy the array e.g. like this:

(bonus: try leaving the var off in front of the concat expression and see how "safe" this version is)

One could argue that it is simply bad form to write javascript and expect it to behave like clojure, but entire books have been written to explain to programmers how to avoid side-effect pitfalls in javascript - and the language is almost unusable without them.

In clojure, there's much less need² for this kind of "meta language documentation" - and none for protecting data. It's guaranteed not to change. In the example above, the most likely thing to trip up a programmer new to clojure is the need for doall (leave it out and nothing prints since map is lazy - in the repl you'll need to assign the output to see the difference - e.g. (def foo (listFruits fruits)). This is still a bug, but it's one limited to the function in question, not the entire code base.

So my conclusion is that clojure is safer because it has fewer (and much less dangerous) gotchas, the impact of mistakes is limited to the scope of the offending line of code (which will likely be a function or even a let block) and you never³ have to keep a mental model of how state is changing as the instruction pointer advances. It's all right there in front of you.

We all make mistakes, but in clojure, mistakes are limited to the context of the function and never due to implicitly mucking about with application state. This adds confidence when making changes, that is simply not there in languages that cannot make such guarantees.

^[1]Clojure is not the only language that features immutability of course - it just happens to be one I use a lot, and like programming in; nor is js alone in having side-effects; i.e. this isn't about championing clojure (or bashing js) it's about immutability, so feel free to substitute your [least] favorite languages as you see fit.

^[2] So far at least. Clojure is still young yet, but I don't expect it'll gain this kind of cruft, if for no other reason than because it won't share javascript's experience of being in the front-line of the browser wars.

^[3] Wanton use of clojure constructs such as ref, atoms & agents can of course lead to such an environment; however even so, clojure provides well-defined protocols for managing change. If the programmer still creates a state-management hell, that's on the coder - as are most problems in coding; no language can enforce safety, only make it easier or harder.
