In this article, we will be talking about how you can download fonts from websites in Chrome or Edge browser using Developer Tools. Both Chrome and Edge come with built-in web developer and authoring tools used to inspect websites directly in the browser. You can do a lot of things with the Developer Tools. For example, it enables you to identify fonts on a website, search within the source file, use a built-in beautifier, emulate sensors and geographical location, and more.

Now, you can also download fonts from a website using Developer Tools. To obtain a font from a website, you will need to go through some options and try a trick. Let’s check out the procedure in detail.

How to  obtain a Font from a Website in Chrome or Edge using Developer Tools

In this post, we are going to show you the steps to obtain a font from a website in Google Chrome. You can use the same steps to obtain a website font in your Microsoft Edge browser. Here are the steps to do that:

  1. Launch Google Chrome.
  2. Go to the website from where you want to obtain fonts.
  3. Open the Developer Tools.
  4. Navigate to the Network tab.
  5. Click on the Font option and select a font to download.
  6. Download the font file.
  7. Rename the downloaded file with the font file extension.

Let us check out these steps in detail!

Firstly, open Google Chrome and go to the website from where you need to obtain a font. Next, go to the three-bar menu and click on the More Tools > Developer Tools option. Alternately, you can also press the Ctrl + Shift + I key combination to quickly open up the Developer Tools panel.

Now, in the opened Developer Tools section, click on the double arrow button and then select and open the Network tab from the top menu bar. After that, reload the website you are on.

Next, click on the Font category and you will see a list of the embedded fonts with respective font names present on the website. You can select a font from the list and you will see its preview in the dedicated panel as shown in the below screenshot.

Now, how to identify the font format? Well, just hover the mouse over the font and see the file extension at the end. Refer to the below screenshot.

After that, simply right-click on the font, and then from the context menu, click on the Copy > Copy Response option.

Next, add a new tab in your Chrome browser and paste the copied response to the address bar in the tab and then press the Enter button. As you do that, a file will be downloaded.

Now, go to your Downloads folder where the above font file is downloaded. You now have to rename this file with the font file extension. For that, first, go to the View tab in the File Explorer and then make sure to enable the File name extensions option. Now, select the downloaded font file and click on the Rename option. Add the identified font file extension (e.g., .woff2) and press the Enter button.

Voila, this is how you obtain a font file from a website.

Since Microsoft Edge is now based on Chromium, like Chrome, you can obtain a font file in the Edge browser following the same steps as above.

Hope this article helped you learn how to obtain fonts from a website in Chrome or Edge browser using Developer Tools.

How to obtain macOS Sonoma beta: 14.2 beta now available

Apple released macOS Sonoma on September 26, 2023, so everyone can now run the latest macOS version on compatible Macs, but not every promised feature was available at launch. Apple will continue to work on macOS14 Sonoma into the summer of 2024 (at which point it will start work on macOS 15). If you are a member of Apple’s beta testing program you will be able to try out the new features before they arrive on everyone else’s Macs.

The developer beta of macOS 14 Sonoma has been available to obtain since June 5, 2023. This year the developer beta isn’t just available to developers who have paid to join Apple’s Developer Program (which costs $99/£79), Apple has opened it up to anyone who is a registered developer. We explain how to get a free developer account below.

The slightly more stable public beta version is also available for anyone who has signed up for the public beta program.

In this article, we’ll run through what you need to do to get your hands on the beta of the next version of the Mac operating system, how to install it, and what you should bear in mind if you don’t want to end up in a pickle. If you have not updated to the latest official release of macOS Sonoma here’s how to update macOS on your Mac.

Update October 26, 2023: The macOS Sonoma 14.2 beta is now available.

macOS Sonoma beta latest version

The first version of the developer beta of Sonoma arrived after the WWDC keynote on June 5, 2023 as expected. On July 12, Apple released the first public beta.

Following the release of macOS Sonoma 14.1 to the public on October 25, 2023, Apple is now working on the development of macOS 14.2.

  • Apple released the first beta macOS Sonoma 14.2 to developers on October 26, 2023.

macOS Sonoma public beta vs developer beta

Apple has made the Developer Beta available to anyone who had registered as a developer, even if they aren’t a paid-up member of Apple’s Developer Program. As a result, people with a basic free developer account were able to obtain the macOS Sonoma developer beta after the keynote on June 5 (we show you how to register below).

Whether you should obtain the developer beta if you aren’t a developer is another question. We don’t recommend you install the developer beta if you aren’t a developer. Instead, our recommendation was to wait for the public beta, which is here now.

There are a few differences between the public and developer betas. The public beta is not the same as the beta that is released through the developer program.

Developers get updates to their beta first, and possibly more frequently. But you should keep in mind that betas are by nature not stable, and because the public beta comes after the developer beta it could be a little safer to install.

The most significant difference is probably the motive of the testers: Developers usually have the aim of ensuring their apps work when the updated macOS is released to the general public, while public beta testers are essentially helping Apple detect bugs and offering feedback on the features. Because of this developers may get to test new features not available in the public beta. 

If you want to get the public beta the first thing you need to do, if you haven’t already, is join Apple’s beta programs read this for more information: How to become an Apple beta tester.

How Get Public Beta Apple

Apple

How to get a free developer account

If you just want a free Apple Developer account so you can access the beta you can get this via Xcode or the Apple Developer app in iOS. Here’s how to do it via the Apple Developer app on an iPhone:

  1. Get the Apple Developer App from the App Store. 
  2. Open the app on your iPhone. 
  3. Tap on Account. 
  4. Tap on Sign In. 
  5. Sign in using your usual Apple ID. 

If you wish to actually publish applications to the App Store or receive support, you’ll need to pay $99/£79 per year for a paid account. You can compare the free and paid accounts here.

How to get the macOS Sonoma beta

The Sonoma developer beta should show up on your Mac if you are running macOS Ventura 13.4 or later, have paid $99/£79 to enroll in Apple’s Developer program (here) or if you have a free developer account (follow the instructions above).

Now the Public Beta becomes available it will also show up on your Mac in macOS Ventura 13.4, as long as you have signed up for the Public Beta program on Apple’s beta webpage, signed the NDA, and enrolled your Mac.

Before you obtain a few warnings:

  • We strongly advise that if you aren’t a developer you don’t obtain the developer beta.
  • We also strongly recommend that you back up your Mac before you upgrade to the Sonoma beta.
  • We recommend that you do not run Sonoma on your primary Mac; ideally, you run it in a separate volume. This should minimize any risks to you.

If you are running macOS Ventura 13.4 or later:

  1. Open Software Updates on your Mac. (System Settings > General > Software Updates.)
  2. You should see two options: Automatic Updates and Beta Updates. Click on the (i) beside Beta Updates.
  3. You can now turn on Beta Updates (if they weren’t already on).
  4. Choose the beta you want to download.
  5. If your developer account is tied to a different Apple ID to your usual one you can change that here.
  6. Click Done.
  7. Now your Mac will Check for updates and eventually show the Sonoma Developer Beta as an upgrade. Click on Upgrade Now.
Get Sonoma Beta

Foundry

If you are running macOS Ventura 13.3 or earlier:

Apple changed the way it delivers betas in Ventura 13.4. If you aren’t yet running that version of macOS you will need to obtain the macOS Developer Beta Access Utility or macOS Public Beta Access Utility.

If you were already running an earlier macOS Public Beta you’ll find the new macOS beta as an upgrade via Software Update. Just click on Upgrade Now. You may have to update to the latest version of your current beta before you can do so, if not follow the steps below to get the beta access utility.

  1. If you are enrolled in the Developer Program, go to Apple’s beta obtain page. Click on Install Profile to obtain the new macOS Developer Beta Access Utility to your Mac.
  2. If you are enrolled as a public beta tester, download the macOS Public Beta Access Utility.
  3. Go to Downloads on your Mac and click on the macOS Beta Access Utility to open it.
  4. Double-click on the dmg file and the installer will run.
  5. Once the new macOS beta is installed Software Update will check to see if there are any updates. Click Update and the latest version will download.
  6. You’ll see a prompt to install the latest macOS beta, click on Continue.
  7. Agree to the Ts&Cs (more on them below).
  8. Click Install.
macOS Public Beta Access Utility

How to update macOS beta versions

Once you are running the beta the updates will come through to your Mac automatically, you just need to click to install.

  1. You will receive a notification when the next update to the beta is available.
  2. Updates will be available via Software Update (in System Settings/System Preferences)
macOS Beta in Software Update

Everything else you need to know about beta testing

That covers how to get the betas, but once you have them what can you do, and what should you do? We’ll cover that below.

Is the macOS beta stable?

By its nature, a beta has the potential to be unstable. Therefore it’s not advised that you install it on a Mac that you rely on. If you have a second Mac that isn’t mission-critical then install it there. We strongly recommend that you don’t risk all by putting the macOS beta on your primary macOS, especially not in the early days of the beta development. 

If you don’t have a second Mac there are a couple of ways you could run macOS beta on your Mac without running the risk of losing data or finding your Mac stops working:

We discuss the safety of the macOS beta and the risks you might be taking in more detail in a separate article.

If the stability of the beta worries you then you are probably better off waiting until the final version is out, or at least waiting until testing has been happening for a few months before getting the beta.

How to prepare your Mac for the beta

Update your software: We recommend you have the latest full version of macOS installed, although Apple says that the macOS Developer Beta Access Utility requires macOS 10.8 or later.

Make space: We’d recommend at least 15GB of available space because the macOS betas tend to be very large. If you end up requiring more space read: How to free up space on Mac. Note that we always recommend that you have at least 10% space free on your Mac at any time, so if you don’t have that expect problems!

Back up: Before you install a beta on your Mac you should make a backup of your data and files. You can find out how to use Time Machine to back up your Mac. We also have a round-up of suitable backup solutions.

How to send feedback to Apple

Should you come across an error or a bug you should use the Feedback Assistant app to provide feedback to Apple. Launch the app and follow the appropriate steps, selecting the area about which you’re providing feedback and then any specific sub-area. Then describe your issue in a single sentence, before providing a more detailed description, including any specific steps that reproduce the issue. You’ll also be able to attach other files.

You’ll also have to deliver permission for the Feedback Assistant app to collect diagnostic information from your Mac.

Beta Feedback Assistant

It won’t always be obvious whether something is a bug or just not as easy to use as you might have hoped. Either way, if your feedback is that something appears to work in an illogical way, Apple will want to know that.

If you are having trouble with a third-party app you can let Apple know by reporting it through the 3rd-party Application Compatibility category in the Feedback Assistant. However, we’d suggest that you also provide feedback to the app’s developer who will no doubt be grateful.

Will I be able to update from macOS beta to the final version?

Beta users will be able to install the final build of the OS on release day without needing to reformat or reinstall.

Can I talk about the beta publicly?

According to Apple and the license agreement all beta testers must agree to, the beta is “Apple confidential information”. By accepting those terms, you agree not to discuss your use of the software with anyone who isn’t also in the Beta Software Program. That means you can’t “blog, post screenshots, tweet, or publicly post information about the public beta software.”

However, you can discuss any information that Apple has publicly disclosed; the company says that information is no longer considered confidential.

How to downgrade from the macOS beta

You can always revert to an earlier version of macOS, though depending on how you back up, it’s not necessarily a painless process.

Start by making sure the data on your drive is backed up, then erase the drive and install the latest public version of macOS. When you first startup your Mac you can use the Migration Assistant to import your data from the backup. Here’s a more detailed tutorial on downgrading from the macOS beta we also have a tutorial on downgrading to an older version of the Mac OS.

Cloudera and Pinecone Unite to Tackle AI Hallucinations with Advanced Vector Database Integration

NEW YORK, Nov. 3, 2023 — Cloudera, Inc., a data company for trusted enterprise artificial intelligence (AI), and Pinecone, a vector database company providing long-term memory for AI, are thrilled to announce a strategic partnership that integrates Pinecone’s AI vector database expertise into Cloudera’s open data platform, aimed at transforming the way organizations harness the power of AI to streamline operations and Excellerate customer experiences.

A market leader, Pinecone’s vector database is critical infrastructure for Generative AI. Pinecone is optimized to store AI representations of data (vector embeddings) and search through them by semantic similarity, something traditional databases are very inefficient at doing. This capability is necessary for adding context to queries against applications that use Large Language Models (LLMs). That added context significantly cuts down on erroneous outputs – often referred to as “hallucinations” – helping search and Generative AI applications deliver responses that are accurate and relevant.

The partnership will see Cloudera integrate Pinecone’s best-in-class vector database into Cloudera Data Platform (CDP), enabling organizations to more easily build and deploy highly scalable, real-time, AI-powered applications on Cloudera. This includes the release of a new Applied ML Prototype (AMP) that will allow developers to more quickly create and augment new knowledge bases from data on their own website, as well as pre-built connectors that will enable customers to more quickly set up ingest pipelines in AI applications. In the AMP, Pinceone’s vector database uses these knowledge bases to imbue context into chatbot responses, helping to ensure useful outputs.

Customers can use this same architecture to set up or Excellerate support chatbots or internal support search systems. This enables them to reduce operational costs by decreasing expensive human case-handling efforts and improving the customer experience with faster resolution times. More information on this AMP and how vector databases add context to AI applications can be found in our blog post here.

“Cloudera’s extensive expertise in data management combined with Pinecone’s cutting-edge vector database creates a formidable partnership. A lot of our customers already manage their data with Cloudera. Now it will be easier than ever for them to build AI applications using their embeddings stored with us and data stored with Cloudera. Together we will enable organizations to deliver unparalleled personalized experiences, drive user engagement, and achieve business success,” Elan Dekel, Vice President of Product, Pinecone.

“We are excited to bring the power of Pinecone vector database and semantic search capabilities to our public cloud customers to accelerate generative AI use cases, and significantly Excellerate the developer experience at scale.” Abhas Ricky, Chief Strategy Officer, Cloudera.

“Integration of Pinecone with CDP adds a very critical new functionality that will help clients build generative AI applications,” said Sanjeev Mohan, founder of SanjMo and former Gartner analyst. “In addition, the planned integration between the open source Apache NiFi-based Cloudera Data Flow (CDF) and Pinecone further bolsters CDP’s emphasis on universal data distribution for AI. CDP customers can bring AI to where their data resides – on-premises, in the cloud or on the edge.”

About Cloudera

Cloudera believes data can make what is impossible today, possible tomorrow. We empower people to transform their data into trusted enterprise AI so they can reduce costs and risks, increase productivity, and accelerate business performance. Our open data lakehouse enables secure data management and portable cloud-native data analytics helping organizations manage and analyze data of all types, on any cloud, public or private. With as much data under management as the hyperscalers, we’re a data partner for the top companies in almost every industry. Cloudera has guided the world on the value and future of data, and continues to lead a vibrant ecosystem powered by the relentless innovation of the open source community.

About Pinecone

Pinecone created the vector database, which acts as the long-term memory for AI models and is a core infrastructure component for AI-powered applications. The managed service lets engineers build fast and scalable applications that use embeddings from AI models, and get them into production sooner. Pinecone recently raised $100M in Series B funding at a $750M valuation. The funding round was led by Andreessen Horowitz, with participation from ICONIQ Growth and previous investors Menlo Ventures and Wing Venture Capital. Pinecone operates in San Francisco, New York, and Tel Aviv.

How to Install iOS 17 Beta Software Updates on Your iPhone

When Apple released the first iOS 17 beta to developers, for the first time it gave non-developers the opportunity to obtain beta software updates on their iPhones for free. Keep practicing to learn how it's done.

General iOS 17 Feature Blue Green
In years past when Apple has announced a major new operating system update, the first wave of betas has officially only been available to obtain if you are a paying subscriber to Apple's Developer Program, which costs $99 a year. Public betas then become available to users enrolled in Apple's Public Beta Software Program after a delay of a few days or weeks after the developer beta has been released. However, since iOS 17, iPhone users no longer have to wait for a publicly released beta to test what's new.

In an unexpected change for 2023, anyone who signs in to Apple's developer account website with their Apple ID gets access to developer beta releases as well, even if they are not a paying member of Apple's Developer Program. This means anyone with an Apple ID can obtain and install the iOS 17, iPadOS 17, and macOS Sonoma betas without waiting for the public betas to launch.

Is My iPhone Compatible With iOS 17?

Note that iOS 17 is compatible with the iPhone XS and newer, meaning that support has been dropped for the iPhone 8, iPhone 8 Plus, and iPhone X. For a full list, iOS 17 supports the following iPhone models:

  • iPhone 14
  • iPhone 14 Plus
  • iPhone 14 Pro
  • iPhone 14 Pro Max
  • iPhone 13
  • iPhone 13 mini
  • iPhone 13 Pro
  • iPhone 13 Pro Max
  • iPhone 12
  • iPhone 12 mini
  • iPhone 12 Pro
  • iPhone 12 Pro Max
  • iPhone 11
  • iPhone 11 Pro
  • iPhone 11 Pro Max
  • iPhone XS
  • iPhone XS Max
  • iPhone XR
  • iPhone SE (2nd generation or later)

Should I Install iOS 17 Developer Beta?

Before downloading the update, it's worth noting that Apple does not recommend installing iOS 17 beta updates on your main iPhone, so if you have a secondary device, use that. This is beta software, which means there are often bugs and issues that pop up that can prevent software from working properly or cause other problems.

Make an Archived Backup of Your Device First

Before installing the beta, make sure to back up your iOS device before installing the software using the following method, otherwise you won't be able to revert back to iOS 16 if things go wrong.

  1. Plug your iPhone into your Mac using the supplied cable.
  2. Allow the accessory to connect by clicking Allow in the dialog prompt.
  3. Open a Finder window by clicking the Finder icon in the Dock.
  4. Click your iOS device's name in the sidebar.
    finder
  5. If this is the first time connecting your device to your Mac, click Trust in the Finder window.
    finder
  6. Tap Trust on your device when prompted, then enter your passcode to confirm.
  7. In the General tab, click the circle next to where it says Back up all of the data on your iPad to this Mac.
  8. If you want to encrypt the backup, check the box next to Encrypt local backup, then enter a password to protect your data.
  9. If you don't want to create an encrypted backup, or you've already set up encrypted backups, click Back Up Now.
    finder

When the backup is finished, you can find the date and time of the last backup in the General tab, just above the Manage Backups button. Remember that this backup will not be overwritten when you manually or automatically back up your iPhone in the future, so you can restore it at any time by using the Restore Backup... option in the same Finder screen.

How to obtain iOS 17 Developer Betas

As of writing, the option to obtain and install the iOS 17 Developer Beta is also available for users who have previously enrolled on Apple's Beta Software Program, and yet the program is officially only supposed to be for Public Betas. This suggests the option is a bug and Apple will likely remove it. But until that happens, if you're currently enrolled to receive Public Betas, you can skip to step 6.

  1. Open Safari on your iPhone and visit developer.apple.com.
  2. Tap the menu icon in the top-left corner of the page, then tap Account.
  3. Under "Sign in to Apple Developer," enter and submit your Apple ID and password using the arrow buttons, then enter the two-factor authentication code sent to your devices.
    developer program
  4. Tap the top-left menu icon again, then tap Account.
  5. Accept the legal terms of the Apple Developer Agreement by scrolling down the page, checking the box, and tapping I Agree.
    dev program
  6. Make sure your iPhone is running iOS 16.4 or later by going to Settings -> General -> Software Update. If it is, and you have just completed steps 1-5 to register a developer account, restart your iPhone. If it isn't, obtain and install the latest update to your device, then wait for it to restart.
  7. Now go back to Settings -> General -> Software Update.
  8. Tap Beta Updates. If you don't see the option, try switching off obtain iOS Updates (Automatic Updates -> obtain iOS Updates), then tap Back and it should appear.
  9. Select iOS 17 Developer Beta in the list, then tap Back.
  10. Wait for the Software Update screen to check Apple's servers. When the iOS 17 Developer Beta appears, tap Download and Install, then follow the instructions and wait for installation to complete.
    software update

iOS 17 Features

‌iOS 17‌ is a major update that introduces a customized look for each person that calls, with the person who places the call able to customize their look. With StandBy, an iPhone placed horizontally turns into a little home hub that displays information like the calendar, time, home controls, and more, and Live Activities can be displayed in full screen too.

Widgets on the Home Screen are interactive, so you can do things like check off an item on a to-do list or turn off the lights without having to open an app. AirDrop has been improved and there's a NameDrop function for sharing contacts quickly, plus you can hold two iPhones together to start a SharePlay session. SharePlay also now works with CarPlay so passengers can play their music in the car too.

Other new features include a journaling app coming later this year, AirPlay in select hotel rooms, improvements to AirPods Pro 2 thanks to a new Adaptive Audio feature, offline Maps, Siri that does not require the "Hey" activation, and improvements to search and spotlight.

Apple Releases iOS 17.2 Developer Beta. Here's How to obtain the Latest iPhone Update

Apple today released the first developer beta of iOS 17.2, only a day after the launch of iOS 17.1 to the general public.

As long as you're enrolled in the Apple Developer Program, which now offers a free tier, you can obtain iOS 17.2 beta 1 to your compatible device, starting with the second-generation iPhone SE and all the way to the new iPhone 15 series.

iOS 17.2 beta 1 finally introduces the Journal app, which Apple first mentioned at WWDC back in June. This early version of Journal is a digital diary that allows you to record your daily thoughts and activities with words, photos, music and even workouts. The new iOS beta also brings collaborations to Apple Music playlists, a translation feature to the Action button and a few enhancements to Messages.

Typically, you have to pay $99 to officially obtain and install any Apple developer beta software, but this year the company is letting anyone get a crack at iOS 17, as long as you join the Apple Developer Program.

Note: If you've already tested out any of the iOS 17 developer betas, you can just go into your settings and you should see iOS 17.2 available to obtain and install.

Read more: You Need to Know About These 3 New Features on the iPhone 15 Pro and 15 Pro Max

Before you go on and install iOS 17.2, you should know that developer beta versions like this aren't intended for general use, especially because they may have unfinished features and issues that can make the iPhone difficult to use. These early beta releases are, instead, for developers, to help them keep their apps up to date and get early access to the upcoming features.

In short, you probably shouldn't install the developer beta on your primary iPhone. If you really want to get iOS 17.2 right now, try to find a spare iPhone that's new enough to work with the latest software.

Read more: NameDrop Finally Hits Apple Watch: Here's Everything You Need to Know

For folks who still want to dive in, we'll show you how to install the iOS 17.2 developer version on your iPhone, as well as what to do in case you want to revert to a stable version of iOS 17.1.

Want to learn more? Here's what you need to know about Vision Pro, Apple's new augmented reality headset. And here's everything new with MacOS Sonoma.

What to know before you obtain the iOS 17.2 developer beta

Because the iOS 17.2 developer beta is an early prerelease version, the software could have bugs and other issues.

Again, if you're thinking about downloading iOS 17.2, do it on a backup or secondary phone, if available. The iOS 17.2 developer beta's issues could cripple your iPhone and make it difficult to use, disabling phone calls or text messages or making it extremely laggy. However, if you only have your main phone or tablet available, make sure to back up your iPhone on iOS 17.1 (the latest version of iOS 17) before updating to iOS 17.2. That way you have the option to return to iOS 17.1 if there are too many issues on the new OS.

Also, you must have an iPhone XS or later to run iOS 17.2.

And most importantly, to obtain the iOS 17,2 developer beta, you must be enrolled in the Apple Developer Program. The full membership is $99 a year, but as mentioned above, Apple is now offering a free membership option, with limited tools and resources, that allows pretty much anyone to obtain and install the iOS 17,2 developer beta for free.

You can also wait to join the Apple Beta Software program next month, which will provide a more stable iOS 17.2 upgrade than the developer version.

You can obtain iOS 17.2 on the iPhone XS and later.

How to enroll in the Apple Developer Program, for free

If you're only interested in testing out the iOS 17.2 developer beta for fun, you don't need to pay for an Apple Developer Program membership. You can easily use your existing Apple ID to sign up for the developer program and obtain developer software onto your iPhone.

1. Go to Apple's Developer website, tap the three-dash menu in the top-right and hit Account.

You can install iOS 17.2 with an over-the-air update on your iPhone

The easiest way to obtain the iOS 17.2 developer beta is with an over-the-air update -- the way you would update to any other new software release on your device. Once you're a member of the Apple Developer Program, free or paid, you'll automatically have the option to install iOS 17.2 from your settings.

Here's how:

1. On your iPhone or iPad, go to the Settings > General > Software Update.

2. Next, go into Beta Updates and tap iOS 17.2 Developer Beta.

3. Go back and tap Download and Install under the new "iOS 17.2 Developer Beta option" that appears.

You'll need to then enter your passcode, agree to the terms and conditions and wait for the update to be installed. The process takes about 10 to 15 minutes, depending on your internet connection. Once your phone reboots, you should have access to the iOS 17.2 developer beta.

All subsequent iOS 17.2 developer beta updates will appear as over-the-air updates here on your iPhone.

Or obtain the iOS 17.2 developer beta using your Mac

Over-the-air updates require a certain amount of storage, and if you don't have that available, your computer is really the only way to update to iOS 17.2 beta without manually clearing out space.

1. On your Mac, go to the Apple Developer Program download page, find "iOS 17.2 beta," click Download Restore Images and download the iOS beta software restore image for your specific device.

2. Connect your device to your computer and enter your device passcode or hit Trust This Computer if prompted.

3. Next, open Finder, click your device in the sidebar under Locations.

4. Hold down the Option key, click Check for Update and choose the iOS 17.2 beta software restore image you just downloaded from the Apple Developer page.

The iOS 17.2 developer beta software will install on your device. Wait for a few minutes and when your phone reboots, you should have access.

If you don't have space on your iPhone, obtain and install the iOS 17.2 developer beta from your Mac.

Cloudera Report Highlights Generative AI Adoption Surge, Cautions on Data Trust Issues

SANTA CLARA, Calif., Nov. 2, 2023 — New research from Cloudera, the data company for trusted enterprise artificial intelligence (AI), has revealed that more than half of the organizations in the US (53%) currently use Generative AI technology and an additional 36% are in the early stages of exploring AI for potential implementation in the next year.

But more than eight-in-ten decision makers for data strategy and management surveyed (84%) are concerned about sharing data with third parties for training or fine-tuning of Generative AI models, alluding to the perception of a still untamed, Wild West-like environment when it comes to data privacy, security, and compliance. In addition, almost all respondents (95%) believe that full control of data during AI model training is key to trusting the AI outputs.

“Generative AI has taken center stage in boardroom discussions – Whilst analytical AI products have been worked on for decades, ChatGPT has accelerated Gen AI innovation and the road to human level performance has shortened across every industry,” said Abhas, Chief Strategy Officer at Cloudera. “Yet there are concerns regarding trust, compliance, authorization, and intellectual property. Organizations are apprehensive about the potential exposure of training models using publicly available data and/or receiving erroneous responses from AI models that have NOT been trained with relevant enterprise context. Our survey results confirm our understanding that data moats are real and organizations who have been successful in creating trusted and secure data sources will have an advantage in producing higher fidelity outputs with Generative AI applications.”

The survey polled 500 IT decision makers (ITDMs) and data scientists in the US regarding their organisation’s status and plans for Generative AI. The results of the study “2023 Evolving Trends: Data, Analytics & AI” were published at the data conference Evolve New York on November 2.

Chatbots Most Relevant Use Case for Generative AI

Enhancement of customer communication with chatbots or other tools (55%), support for product development (44%), and concept development (44%) are cited as the main benefits generative AI offers organizations. Also named are support for data analysis (34%), software development (32%) or the automation of activities and processes (28%).

“The success of these initial use cases, such as chat Q&A, text summarization, and co-pilot productivity enhancements, relies on bringing the models to the data, at the point of its creation and origination, and not the data to the models! For example, a large financial institution is currently making 4 million decisions a day by processing all data through their trusted AI Lakehouse,” said Abhas.

Research Methodology

Conducted by Coleman Parkes Research, Cloudera’s survey evaluated the opinions of 500 ITDMs and data analysts in the US. Respondents came from organisations with more than 1,000 employees within the following industries: finance, banking, insurance, manufacturing, telecommunications, retail and e-commerce, government and public sector, healthcare and life sciences, technology and software, energy and utilities, education, media and entertainment.  The research was conducted between June and August 2023.

AI at Work: New UiPath business automation platform features 'transform the enterprise'

2023.10 platform release includes powerful new capabilities with Specialised AI and Generative AI, new developer productivity tools, and UiPath Automation Cloud™ improvements

COMPANY NEWS: UiPath (NYSE: PATH), a leading enterprise automation software company, today announced its latest platform features that help customers gain real value by transforming millions of tasks and thousands of processes across the enterprise with AI and automation, creating capacity for new ideas and unleashing worker productivity.

A recent report by UiPath and Bain & Co. revealed AI is accelerating business change, with 70% of respondents asserting that AI-driven automation is either “very important” or “critical” in fulfilling their organisation’s strategic objectives and 74% stating they anticipate a positive return on investment from their automation endeavors. Still, some leaders and organisations are struggling to adopt AI across their enterprises. According to a report from McKinsey, almost half of organisations (45%) have no AI at scale.

New innovations from UiPath lower the barrier between vision and reality for organisations by using AI to uncover automation opportunities, expand what can be automated, and make automation faster, easier, and more accessible to all.
