Suggested April 2024 Saurik’s Ted Talk, “Even Software Should Have Screws”

Jay Freeman, better known as saurik, recently gave a TED talk on the philosophy of mobile software. He compared the iPhone’s App Store and the jailbreak mentality to how consumers buy and modify cars. He made the case for what he has based his career on: that consumers do not want the software limitations that Apple maintains on iOS.

The first half of saurik’s TED talk explains the state of the car industry, and the consumer approach to buying and modifying cars. His comparison is interesting, and it definitely merits his point about Apple’s App Store philosophy…

Saurik described how some buyers of cars don’t mind keeping their car the exact way that they bought it. However, he made the case that most buyers of cars like to add and modify the look and features of their investment; whether it be the color, seats, or stereo system. He argued that this same mentality needs to be applied to the App Store.

In Hacker News, saurik wrote a post clarifying the points of his TED talk,

“The idea is that the App Store is designed to install “applications”: units of software that typically involve an icon on some kind of launcher that opens a window into some new functionality the device previously did not have.

These programs are not just apps: they are extensions to other applications on the device. We also see this in the form of custom launchers, dialers, and widgets: Android has numerous ways that developers can extend the core functionality of the handset in ways that escape the trap that is the icon.”

The goal of saurik’s talk was to basically praise the jailbreak mentality, which makes sense. Whether or not his assumptions about consumers tendencies are based in factual, statistical evidence, there is definitely a point to what he had to say.

“Go look at your average jailbroken iPhone: the stuff people are developing and installing is amazing. There are almost no limits to what you can change on the device; it isn’t open source, but it is damned close. No system feature or application is immune to the influence of small and large changes. And, if you really insist that open isn’t open until it is open source you can gut the bootloader and install Android on the thing thanks to the iDroid project.

This is why I absolutely hate it when I read people focusing on rejected applications or “opening up” the app store. In a future where Apple did exactly what you are asking them to do almost nothing will have changed: people will still need to jailbreak their phones and developers will still be writing and distributing all of this cool software using Cydia.”

Saurik actually came to Apple’s defense in his post after the TED talk. He talked about the reasons that Apple denies apps, and that there are legal reasons why Apple has to function the way it does. In fact, he believes that Cydia is not like the App Store at all. There are very few actual “apps” in Cydia, mostly hardware and software tweaks.

In the end, saurik wants people to stop pleading for Apple to open up the App Store like the Android Marketplace.

“So please… PLEASE… I implore you: drop the battle to get Apple to open up their App Store. Instead, work on getting Apple to open up their device (and, in the case of desktop Mac OS X, to maintain the reasonable open-ness of their MacBook line of computers). Until users are able to install whatever software they wish on the hardware that they own we will not truly have won back any of our freedom.”

I encourage you to watch saurik’s 13 minute TED talk. He makes an insightful presentation from an intriguing point of view.

What do you think about what he had to say? Do you agree with what he says; that the OS needs to be opened up instead of simply the App Store?

Top 8 Reasons For Accountants Should Have Accounting Software On The Cloud

We have made significant progress in the last few years towards a digital world. The following data is available.

A study by Statista shows that digital transformation spending reached USD 1.3 trillion by 2023, two years ago. Compared to the previous year, digital transformation spending saw a 10% increase. This is not all, the global digital transformation spending is predicted to reach 2.4 Trillion in the next two years.

Technology must be flexible, scalable, and practical as the digitally-driven industries shift to new ways of working. Cloud hosting is one of these comfortable technologies that can help you increase data security, scalability, and accessibility.

Host accounting software in the cloud to increase employee productivity and improve business operations efficiency

Why should you host your accounting software on the cloud?

Host accounting software in the cloud and you can do everything from collecting large amounts of data to processing high-level tax season information.

Here are Some of The Benefits of Hosting Your Accounting Software in The Cloud 1. Unified Working

You can collaborate in one place if you have accounting software hosted on the cloud. Your application and data are kept in one central location that can be accessed by IT administrators at any time. This allows for fewer errors and better control over the IT team.

2. Remote Accessibility

The best thing about hosting an accounting program online is the possibility to access it remotely. If you have QuickBooks Pro installed, you can only access the software from the dedicated desktop hosting it. The cloud allows you to access the software from any location.

3. Regular Backups

Hosting accounting software in the cloud means that we use services provided by a cloud hosting company. Your CSP usually takes automated backups of your data. The system creates new backups at regular intervals to replace the older ones.

Your backup files are kept on cloud servers for between 15 and 30 days depending on which provider.

Access your data from your backup in case of a natural disaster. Redundancy is a principle that the cloud uses to reduce dependency on office infrastructure, even in the event of a disaster.

4. Third-Party Integrations – Vital for Accounting Software

Third-party integrations with the cloud are easy. For a seamless stream of data, you can integrate your tax and payroll software with your accounting software. This integration allows your team to enjoy seamless data connectivity, improve productivity, and have a more unified working environment.

5. Multi-Device Access

Remote access is possible when accounting software is hosted on the cloud. You can also access data and software from any device. This applies to your smartphone, desktop, tablet, and laptop. Any operating system can be used, including Windows, Mac OS, Android, iOS, and Windows.

Your accounting software, for example, is hosted in the cloud. You have previously used it in a Windows environment at your office. The same interface and cloud image can be used to open the same software from a MacBook.

6. Data Security

Host accounting software in the cloud to increase security for your business. These are just a few ways to do it:

The provider physically secures the cloud infrastructure with the aid of a CCTV camera or other equipment.

The cloud employs various security measures, including multi-factor authentication, access control, DDoS prevention, updating, patching, Intrusion Detection, and Prevention.

7. Affordability

Hosting accounting software in the cloud is a great deal. Your IT team will spend more time and resources maintaining desktops in-house than using the cloud. You must also make sure that your desktops are always updated and repurposed. Hardware is expensive.

Cloud computing eliminates the need to manage IT infrastructure. You can also reduce the size and complexity of your IT staff. We can also upgrade our system resources from the cloud so that we don’t need to buy new PCs.

Life Abhors Arsenic, Even In Extremis

Sunrise at Mono Lake in eastern California, bounded to the west by the Sierra Nevada Mountains. This ancient alkaline lake is known for unusual tufa formations rising from the water’s surface, as well as for its hypersalinity and high concentrations of arsenic. via Science/© 2010 Henry Bortman

An exquisitely detailed chemical structure enables microbes to selectively choose beneficial phosphorus over its poisonous cousin, arsenic, even when the dangerous chemical far outweighs the essential one. A unique method of chemical bonding helps the bacteria’s phosphate-binding proteins sniff out phosphorus, according to researchers in Israel, France and Switzerland. It’s yet another in a string of papers responding to a claim that bacteria could subsist on arsenic.

In late 2010, NASA announced that a newly studied strain of bacteria from an arsenic-rich California lake could swap arsenic for phosphorus in its DNA, ATP and other biomolecules. It was swiftly criticized for a variety of reasons, primarily because life has never been shown to survive without phosphorus. Felisa Wolfe-Simon, the lead author on that now-infamous study, maintained that the bacteria — called GFAJ-1 — did just that, surviving with arsenic as a phosphorus substitute.

In the following two years, several papers have been published that cast doubt on the original findings. But it was never clear how bacteria would be able to tell the nearly identical molecules apart. Mikael Elias and Alon Wellner of the Weizmann Institute of Science in Israel aimed to figure this out.

They studied periplasmic phosphate-binding proteins, which are involved in the uptake of phosphorus into bacterial cells. They studied an analog of GFAJ-1 in the lab and figured out that it, along with several other bacterial strains, is capable of discerning what is phosphate and what is arsenate, selectively binding to the phosphate. Their PBPs can detect the very tiny — just 4 percent — difference in the thermochemical radius between the two molecules, thanks to reactions imposed on hydrogen bonds in the protein. The full paper explains in more detail here.

“PBPs therefore seem to have evolved a unique mode of binding that is capable of distinguishing between the highly similar phosphate and arsenate,” the authors write.

It appears that many microbes can do this, but GFAJ-1 can really do it, extracting phosphate at arsenate-to-phosphate ratios that are more than 3,000-fold higher than those observed in Mono Lake, where it was found. This reaction to evolutionary pressure suggests that the subtlest of biochemical changes can make the difference. The authors acknowledge that the origin of this high phosphate selectivity remains unknown.

For her part, Wolfe-Simon said the results represent the type of “careful and interesting studies that aid the community.”

“They have helped us understand molecular level discrimination between arsenate and phosphate in GFAJ-1 and other microbes. We agree, the ecological connection and differences in phylogenetic relationships between the two PBP was quite interesting,” she said in an email to PopSci.

But she said the study, like others before it, still does not address the question raised by her work: that of intracellular arsenate. “We are excited to see these and other studies continuing to answer questions regarding phosphate and arsenate, notably where in the cell the arsenate resides,” she wrote.

The paper appears in an early online edition of Nature.

Use Of :Even And :Odd Pseudo

The CSS contains various pseudo-classes. The ‘:even’ and ‘:odd’ are among them. It is used to select the alternative child elements. Sometimes, developers require to design alternative elements using the different styles. In such cases, they can use specific CSS selectors to select the even and odd elements.

In this tutorial, we will learn to use the ‘:even’ and ‘:odd’ pseudo-classes with list items.

Using the ‘:odd’ Pseudo-class With List Items

The ‘:odd’ pseudo-class is used to select the HTML elements which are at odd positions. We can use the ‘:odd’ class with the nth-child() CSS method to select all child elements of the list items.


Users can follow the syntax below to use the ‘:odd’ pseudo-class to select all list items at odd positions.

li:nth-child(odd) { /* CSS code */ }

In the above syntax, we used the ‘nth-child()’ CSS method and passed ‘odd’ as a parameter to select odd child elements.


In the example below, we created the list of items containing the ‘red’ and ‘green’ alternative text. We used the ‘li:nth-child(odd)’ selector in CSS to select all odd list items. In the output, users can observe the red color of the list items placed at odd positions.

li:nth-child(odd) { color: #ff0000; }


In the example below, we created a list related to foods and gave the ‘foods’ class name. We used the ‘.foods :nth-child(2n + 1)’ CSS selector to select odd items. Here, users can observe the space between the class name and the nth-child() method. Also, we passed the ‘2n+1’ as a parameter rather than odd, as both work the same.

In the output, we can see that odd elements are styled properly.

.foods :nth-child(2n + 1) { padding: 5px; margin: 5px; color: blue; background-color: aqua; border: 3px solid red; width: 300px; }

Using the ‘:even’ Pseudo-class With List Items

The ‘:even’ pseudo-class is used to select the elements which are placed at even position. We need to use it with the nth-child() method.


Users can follow the syntax below to use the ‘even’ pseudo-class with list items.

li:nth-child(even) { /* CSS code */ }

In the above syntax, users can write the CSS code in the declaration block to apply it to even elements.


In the example below, we created the list item. It contains the ‘pink’ and ‘blue’ alternative text.

We selected the list item in the CSS and used the nth-child(even) method to apply a specific style to the even list items. In the output, users can observe that it changes the color of the text placed at an even position.

li:nth-child(even) { color: blue; }


We created the list item in the example below containing the car brand names. After that, we used the ‘.cars :nth-child(2n)’ CSS selector to select the even elements in the list item. Here, ‘even’ is replaced with ‘2n’. However, it gives the same output as ‘even’.

.cars :nth-child(2n) { padding: 5px; margin: 5px; color: red; background-color: green; }

Users learned to use the ‘:even’ and ‘:odd’ pseudo-classes with the list items. As ‘:even’ and ‘:odd’ pseudo-classes are not supported by some browsers, we require to use them with the nth-child() method.
