Suggested December 2023 Opinion: Itunes Needs To Be Rebuilt From Scratch, But Not Split Into Separate Apps
For some reason, a popular opinion floating around the web these days is that splitting iTunes up into a bunch of separate apps that all do one individual task each would be a vast improvement on the current one-app-for-everything design. “They did it on iOS,” the logic goes, “so why not do it on the Mac as well?”
After pondering this suggestion for a while, I’m fully convinced that doing so would that be an unnecessary over-complication of the entire ecosystem.
Let’s consider exactly what functions in iTunes could be broken out into separate applications. At the moment iTunes is used for listening to music and podcasts, watching music videos and movies, playing streaming radio, managing audiobooks, syncing iOS devices, making purchases from Apple’s various digital stores (with the exception of iBooks), and downloading iTunes U content.
So in order to break up iTunes based on the iOS model (and assuming audiobooks get moved into the existing iBooks app), we’d need to have several different apps:
A Music app solely for managing songs and listening to Apple Music or Beats 1
A separate Videos app that houses music videos, movies, and TV shows
An app dedicated to syncing media to an iOS device
A separate iTunes Store for purchasing music and videos
An entirely different store for buying iOS apps
An iTunes U app for viewing that material (probably with an integrated store)
A Podcasts app for subscribing and listening to podcasts
This model works on iOS because mobile applications have limited screen real estate, meaning each app needs to be focused on a single function. You can’t cram an infinite number of icons in the tab bar at the bottom of the screen, so instead, you break out features and hide them behind different home screen icons.
On the Mac, this problem doesn’t exist. We have much more screen space to work with, and the Mac’s entire interface is designed for apps that are able to do many related tasks.
Another problem arises with some of apps dedicated to specific types of content. On iOS, music videos can now appear in the Music app as part of the Apple Music service, even though there’s a separate Videos app where your purchased videos go. Do we break out music videos and movies into two separate apps? Do we put music videos entirely in the music app, and let Videos hold only movies and TV shows? Do we just call that the Movies app? Could a Movies app also store home videos exported from iMovie?
Both of these points lead to a similar conclusion: we should combine apps that serve related purposes. Music, videos, and movies could all be combined into one media manager. iTunes U and podcasts could be added there as well.
So now we’ve reduced the above list to the following:
A Media app for music, radio, videos, podcasts, and movies
An app dedicated to syncing media to an iOS device
A separate iTunes Store for purchasing music and videos (and maybe podcasts?)
An entirely different store for buying iOS apps
The App Store can be combined into the iOS manager since that’s the only app that can sync those apps to mobile products. This puts us at three apps:
A media app for music, radio, videos, podcasts, and movies
An app dedicated to managing iOS devices and downloading mobile apps
A separate iTunes Store for purchasing music and videos
So, three things: a media playback app, a media store, and a mobile media syncing app. A media playback app, a media store, and a mobile media syncing app. Are you getting it? These are not three separate apps. This is one app. And we are calling it “iTunes.”
Like it or not, iTunes is one app because the all-in-one approach works. Right now you might think that you want three or four or seven separate apps for micromanaging every little aspect of your media collection. You might think you want your dock filled with half a dozen different icons for tasks that could easily be accomplished in one bundle.
But trust me: you don’t want that. It’s a bad idea. Soon you’d be complaining that seven apps crash too often or take too long to do something instead of just one. You’d wish you could get to your podcasts and music all at once. You’d get annoyed at having to deal with it all.
I’m not saying iTunes is a great app. Like most of the software Apple has released in recent years, they’ve dumbed down things that don’t need to be dumbed down and made other things more complicated than they need to be. They’ve released yet another buggy piece of software that gets harder and harder to deal with on a daily basis. This isn’t new.
iTunes isn’t a slow, buggy, pain to use because it does too much stuff. It’s like that because it’s built on old code that should have been put out to pasture five years ago. Taking the current functionality and breaking it into separate apps is just going to spread that pain around a little bit more.
The idea is just as ridiculous as Facebook forcing everyone to download a separate app simply to send messages while blocking access to the inbox from the main client—a move that may have put Messenger at the #1 spot on the free app listings, but also earned it an average review of one star at the time.
So yes, nuke iTunes from orbit and start from scratch. Please, Apple, for the love of all that is good, build us a new, less-bloated, less-buggy, version of this app. While you’re at it, perhaps reconsider basically everything about the interface and bring back the simplicity of older versions.
Just don’t overcomplicate everything by needlessly dragging OS X into the iOS world with separate apps for every single function.

Question: can you create a single formula to split a string into characters so that each character is in its own cell?
i.e. can you create a single formula in cell B1 that creates the output shown in this example:Solution 1: Using MID and SEQUENCE
Assuming the string is in cell A1, then this formula outputs the characters in a vertical orientation (column):
To change to a horizontal orientation (row), modify the formula to:
Complex formulas are best understood by working through layer-by-layer, starting from the inside, using the onion framework.
Applying that here, we begin with a LEN function to calculate the length of the string in A1.
The SEQUENCE function creates a numbered list 1, 2, 3, etc. up to the value corresponding to the number of characters in the original string.
Next the MID function splits the string into single characters and the array formula applies it to each character.Solution 2: Using REGEXREPLACE and SPLIT
This succinct and beautiful formula uses the REGEXREPLACE formula to insert a character between each character in the original string.
The SPLIT function is then used to break this new string apart based on the inserted character “✂️”.
As it’s written above, this formula outputs the characters in a horizontal orientation. To change to a vertical orientation, wrap it with a TRANSPOSE function.Solution 3: Using REGEXEXTRACT and REPT
This is another clever formula to split a string into characters.
It begins with the REPT function and LEN function to create a string like this (.)(.)(.)…etc., where the number of bracket groups corresponds to the number of characters in the original string.
This feeds into the REGEXEXTRACT formula which extracts each bracket as a single character group in its own cell. Very cool!
Again, this output is a horizontal output, so wrap it with a TRANSPOSE function to switch to a vertical orientation.Solution 4: Use REGEXEXTRACT and REGEXREPLACE
Another exceedingly clever REGEX formula solution!
The REGEXREPLACE adds brackets around each character in the string, e.g. “Google” becomes “(G)(o)(o)(g)(l)(e)”
Next, REGEXEXTRACT extracts each bracket group into its own cell.
As with earlier solutions, TRANSPOSE can be used to convert to a vertical orientation.The Challenge Part II: Recombine In Random Order
Question: can you create a single formula to randomize the characters in a string?
i.e. can you create a single formula in cell B1 to create a copy of the string with the letters in random order:
The key to this question was to use the solution from part 1 inside a SORT function and use a random array to randomize the order.
Here’s the full formula to randomize the characters of a string in cell A1:
The RANDARRAY function creates a random array with a length matching the length of the string in cell A1, calculated by the LEN function.
This is then fed into the SORT function as the sorting column. The characters are passed to the SORT function as the range to sort.
Finally, the list of randomized characters is joined together with the JOIN function.
Note how it doesn’t require the array formula designation because it all happens within the SORT function, which can already deal with arrays.

Electricity is highly perishable. If not used at the moment it is created, it rapidly dissipates as heat. Full decarbonization of the electric grid can become a reality only when vast amounts of solar and wind energy can be stored and used at any time. After all, we can’t harness renewable energy sources such as solar and wind 24/7.
At present, lithium-ion batteries make up a considerable chunk of the market for energy storage. But they are expensive, involve mining rare metals, and are far from environmentally sustainable. Finding an alternative that is less ecologically degrading is crucial—and so far, scientists are analyzing replacements for lithium-ion batteries with the help of raw materials such as sodium, magnesium, and even seawater. But in the last few years, the energy industry has been investing in metal-air batteries as a next-generation solution for grid energy storage.
In 1932, zinc-air batteries were the first type of metal-air battery, widely used in hearing aids. Three decades later, NASA and GTE Lab scientists tried to develop iron-air batteries for NASA space systems but eventually gave up. Still, some researchers are chasing after the elusive technology.The limits, and potential, of metal-air batteries
Researchers believed that, theoretically, metal-air batteries could have higher energy density than lithium-ion batteries for more than six decades. Still, they have repeatedly failed to live up to their full potential in the past.
In a lithium-ion battery, the process of power generation is straightforward. Lithium atoms merely bounce between two electrodes as the battery charges and discharges.
Involving air, however, makes the process more tricky, and adds an added challenge—the difficulty in recharging. Oxygen reacts with the metal, creating a chemical that then sets off the electrolysis process, discharging energy. But instead of a reaction that can go back and forth, in metal-air batteries, the transfer is most of the times only one way. Thanks to the constant flow of atmospheric oxygen into a metal-air battery, once you start it up, the battery can corrode quickly even when left unused and have a stunted shelf life.
Additionally, metal-air batteries’ watt-hours per kilogram—that measures the energy storage per unit of the battery’s mass—is not currently exceptionally high. This is the main reason why electric vehicles now cannot utilize metal-air batteries such as iron-air, Chiang tells Popular Science. “Lithium-ion batteries have 100 watt-hours per kilogram. But for iron-air, it was only 40 watt-hours per kilogram. The rate at which energy is stored and then discharged from the battery is relatively low in comparison,” he says.
[Related: We need safer ways to recycle electric car and cellphone batteries.]
But he argues that despite these limitations, stationary energy storage might utilize iron-air batteries. At a start-up called Form Energy, Chiang and his colleagues have been developing a new, low-cost iron-air battery technology that will provide multi-day storage for renewable energy by 2024.
“Even though it did not work out for EVs, iron-air batteries can be commercially scaled up for energy storage and help mitigate climate change by mid-century,” adds Chiang, who is also chief science officer at Form Energy.New designs for metal-air batteries
Chiang’s team fine-tuned the process of “reverse rusting” in their battery technology that efficiently stores and releases energy. As the iron chemically oxidizes, it loses electrons sent through the battery’s external circuit to its air electrode. Atmospheric oxygen becomes hydroxide ions at the air electrode and then crosses over to the iron electrode, forming iron hydroxide, which eventually becomes rust.
“When you reverse the electrical current on the battery, it un-rusts the battery. Depending on whether the battery is discharging or charging, the electrons are either taken away from or added to the iron,” explains Chiang. He claims that the battery can deliver clean electricity for 100 hours at a price of only $20 kilowatts per hour—a bargain compared to lithium-ion batteries, which cost up to $200/kWh.
But iron isn’t the only metal on the rise. As the race to develop sustainable metal-air batteries for energy storage accelerates, several companies and their researchers are busy investing in zinc-air and aluminum-air batteries.
[Related: Renewable energy needs storage. These 3 solutions can help.]
Materials scientists at the University of Münster in Germany have reworked the design of zinc-air batteries with a new electrolyte that consists of water-repellant ions. In traditional zinc batteries, the electrolytes can be caustic with a high pH substance, making them corrosive enough to damage the battery. The researchers overcame this issue by ensuring that the water-repellant ions stick to the air cathode, so that water from the electrolyte cannot react with incoming oxygen. The zinc ions from the anode can travel freely to the cathode, where they interact with atmospheric oxygen and generate power repeatedly.
As researchers are getting closer to developing rechargeable zinc-air batteries, a Canadian company, Zinc8 Energy, has already unveiled its product. The start-up uses zinc-air batteries with a storage tank that contains potassium hydroxide and charged zinc. Electricity from the grid splits chemical zincate into zinc, water, and oxygen. This charges zinc particles and stores electricity.
When the electricity needs to feed into the grid, the charged zinc syncs with oxygen and water, releasing the stored electricity and producing zincate. Following that, the entire process begins again. The group announced introducing these zinc-air flow batteries to the global market by installing their technology in a solar-paneled residential building in Queens, New York.
Like iron, zinc is widely available and has existing supply chains. Another metal that is also abundant, aluminum, is also being used to develop aluminum-air batteries. But unlike zinc-air batteries, aluminum-air batteries cannot recharge, says Chiang. The carbon footprint of aluminum production is also higher than other metal-air battery options.
By 2028, the global metal-air battery market is expected to reach $1,173 million, mainly for providing energy storage solutions. But for now, investors, industry analysts, and consumers alike are eagerly waiting for the next big breakthrough.
