According to the usage statistics of user application from Microsoft, 60% of the time people spend on the PC is within the web browser. Google Chrome is a cross-platform web browser developed by Google based on Chromium project. According to StatCounter website stats, by January 2022, the market share of Chrome browser is over 63% across all platforms worldwide.

Hybrid core architecture combining high performance cores and power-efficient cores became more and more popular, especially after Intel launched the Alder Lake CPU product. Performance cores are designed to provide maximum compute performance, while efficient cores are designed for maximum power efficiency. Usually OS schedulers can manage hybrid core scheduling, but they lack details of application behaviors, like critical paths. It’s difficult for OS schedulers to cover all scenarios.

We come from the Web Optimization team, and focus on power and performance optimization for Web platforms, mainly Chromium, aiming for better user experience on IA. This article introduces our work to utilize hybrid core capability to schedule specific threads/processes’ execution in Chrome browser to efficient cores, which adopts dynamic policies to reduce power consumption on different levels based on device state. All the analysis and tests below are performed on the Chrome OS platform.

Overview

On the hybrid core platform, Chrome can schedule threads to efficient cores to save power consumption. However, putting browser threads on efficient cores all the time is impractical since lots of threads may surge and demand higher performance. So we propose a hybrid core scheduling technology in Chrome browser to apply dynamic throttles on specific non-critical threads through scheduling them to efficient cores to execute. The technology is based on Web runtime scenarios, like background/idle/ads/video, as the importance of threads would change in different scenarios. Moreover, device information, like battery/thermal status and hybrid core information, need to be exposed to Chrome. Based on them, hybrid core scheduling would apply different core allocation policies to balance power and performance. Normally we schedule low priority threads to efficient cores. But when the device is in a critical stage like running out of battery, the scheduling policy would be more aggressive to prolong device usage time. The application of scheduling policy relies on the OS support, and we can use thread priority or QoS mechanism according to the customs of the OS. On Chrome OS, currently we change thread priority and its cgroup association. Whole architecture of the proposal is shown in Figure 1.

Figure 1: hybrid core scheduling in Chrome browser

Implementation

The implementation of hybrid core scheduling technology mainly contains three parts, scenario detection, scheduling policy, and OS support work.

Scenario detection

First we need to determine the current scenario of a process based on inputs from various browser components. For example, the Chrome render process has a status about background state, which indicates whether the process is foreground or background scenario. For another example, Chrome has an Ad Tagging mechanism to detect ads and the resources they load in the browser. Ad Tagging works by matching resource requests against a filter list to determine if they’re ad requests. An iframe will be marked as an ad iframe if its url matches the filter list, if the tagged script is involved in the creation of the iframe, or if its parent frame is an ad iframe. If all frames are ad frames, the render process would be tagged as an ad process. The browser collects all these inputs and uses a prioritization mechanism to decide the overall mode for the process. Based on the scenario, we adopt an appropriate scheduling policy next.

Scheduling policy

The scheduling policy varies based on the device status. As shown in Figure 1, the browser will monitor the power status of the device via APIs provided by the OS, including the battery level, charging status and the thermal state. For hybrid core scheduling, two stages are defined below.

The first one is the normal stage, which means the battery level is over 20% or the device is charging, meanwhile the thermal state is normal. In this stage, the users care more about the performance than power consumption, so we only schedule low priority threads/processes to efficient cores, like the background processes or the threads handling low priority tasks such as logging/profiling.

The second one is the critical stage, which means the battery level is very low without charging, or the device is in critical thermal states, or the web developer explicitly wants to enter power saving mode, like using battery-savings meta tag. In this stage, we’re going to apply more aggressive policies to save more power, prolong device usage time or avoid thermal throttling due to high CPU temperature. Under this circumstance, many threads/processes in normal priority will be scheduled to efficient cores as long as they are not involved in UX critical tasks.

OS support work

There is some work required to be done to make Chrome utilize OS capability. Battery and thermal status are two important factors to UX. Based on them, Chrome could make appropriate policies to balance performance and power consumption. Previously, there was only battery status exposed to Chrome. Our team has landed a thermal status notification feature in Chrome. In the feature, we introduced 4 thermal levels: Nominal, Fair, Serious, and Critical referring to Apple’s Thermal Hinting API. So that Chrome can get the real-time thermal status. With battery level, charging and thermal status reported, Chrome would decide which stage to enter and apply different scheduling policies.

Furthermore, we have built a bridge between Chrome threads and efficient cores on Chrome OS using the existing cgroup mechanism. Background priority threads are placed in a specific cgroup, which has a specified CPU set. On hybrid core platforms, efficient cores are likely to be allocated for the group. So if we want to schedule unimportant threads to efficient cores to execute, we can lower the thread priority and put them in the non-urgent cgroup. The scheduling is dynamic. When the threads become important (e.g. switch to foreground), we would raise the thread priority to normal right away, hence remove from the specific cgroup.

Experiments

We use the local build Chromium browser to evaluate the power impact of hybrid core scheduling per each scenario, currently focusing on background renderer processes, ads processes, and idle processes (idle is a state defined in the Chrome RAIL model). According to the experiments performed on Alder Lake Chromebook, we observe 4.2% CPU package power reduction for web browsing when scheduling idle processes to efficient cores, and 3.8% CPU package power reduction when dispatching advertisement processes. At the same time, we use a 4-tab browsing workload to test the power impact of placing background processes on efficient cores, and see 0.9% CPU package power reduction. The power saving would be larger when the number of background tabs and page activities increase.

The experiment data shows that we achieve distinct power reduction by utilizing hybrid core capability in Chromium browser to schedule non-UX critical processes/threads to efficient cores in chosen scenarios, which helps extend device battery life.

Future Work

We will continue to explore more scenarios, which don’t demand high performance, and corresponding processes/threads can be scheduled to efficient cores. Besides, as for some scenarios like ads and idle, running on efficient cores might have performance impact, we are about to conduct performance evaluation soon and adjust the scheduling policy accordingly. Furthermore, we intend to extend our analysis and hybrid core scheduling optimization to Windows and Linux platforms.

Hotspots—what are they, where are they, and how can you connect to them while protecting your privacy and security?

If you’ve ever tried to answer an email or surf the Internet from your mobile device in public—or even at the office or your house—chances are you connected to a Wi-Fi hotspot. Not only is this connection highly convenient, you also didn’t have to use your smartphone’s data. Not surprisingly, hotspots are becoming an essential part of public infrastructure—and our Internet experience.

Millions of people every day connect to public hotspots for their data needs. By some estimates, there are almost 200 million hotspots around the world, and there will be one hotspot for every 20 people on earth by 2018. Thanks to our modern always-on digital lifestyle, people expect to be constantly connected, and public Wi-Fi access points are expanding to a global network of hotspots to meet those needs.

Before we dive in to how to connect to a hotspot and related security issues, let’s define what we mean. While some people use the terms “hotspot” and “mobile hotspot” interchangeably, they have distinct meanings.

Hotspot: A hotspot is a physical location where people can access the Internet, typically using Wi-Fi, via a wireless local area network (WLAN) with a router connected to an Internet service provider. Most people refer to these locations as “Wi-Fi hotspots” or “Wi-Fi connections.” Simply put, hotspots are the physical places where users can wirelessly connect their mobile devices, such as smartphones and tablets, to the Internet.
A hotspot can be in a private location or a public one, such as in a coffee shop, a hotel, an airport, or even an airplane. While many public hotspots offer free wireless access on an open network, others require payment. Later in the article you’ll learn how to connect a mobile device to a Wi-Fi hotspot.
Mobile hotspot: A mobile hotspot (sometimes called a portable hotspot) is a hotspot that’s just that—mobile! While a “regular” Wi-Fi hotspot is tied to a physical location, you can create a mobile hotspot by using your smartphone’s data connection to connect your laptop to the Internet. This process is called “tethering.” More on this process later.
You should also know these terms when you’re talking about Wi-Fi hotspots.
Access point (wireless access point): A wireless access point (WAP) is a networking device that allows a Wi-Fi compliant device to connect to a wired network. The WAP can either be physically connected to a router or be integrated into the router itself. A WAP is not a hotspot, which is the physical location where Wi-Fi access to a WLAN is available.
Wi-Fi: Wi-Fi is the technology that allows your smartphone or computer to access the Internet through a wireless connection. It uses radio signals to send and receive data between your enabled device and the WAP.
SSID: A service set identifier (more commonly known as an SSID) is the unique name of a wireless network. You’ll need to know the name of the wireless network to connect to it. Your computer or smartphone can search for available wireless networks; often people name their network for easy identification—anything from “Bob’s phone” to “hotel guests” to “Get off my LAN.”

Now that you understand some of the terms associated with hotspots, let’s learn how to connect to them.

How to Connect to a Wi-Fi Hotspot

You probably connect your smartphone or laptop to the Internet via several Wi-Fi hotspots throughout your day, whether you’re at your office, in your home, or at public locations like coffee shops and airports. Using hotspots is an easy way to keep connected to your busy life.

Connecting to a wireless hotspot is a simple process. Let’s use your smartphone as an example. You want to answer an email at the airport while you’re waiting for your flight, and you don’t want to use your data. You can set your smartphone to notify you when it’s in range of a wireless network, or you can find wireless networks through your phone’s settings. The steps you need to follow to connect to the Wi-Fi hotspot will depend on the device—Android*, iPhone*, or another brand—but here is an overview.

Click the wireless icon on your device to see the names of nearby wireless networks. Select a wireless network; in some cases, you might also have to click “Connect.”
Enter the security key or the password. Most wireless networks are secured and require a password to accept a connection. Some networks are unsecured or open and do not require a password; you should take care when accessing them as they could introduce a security risk.
Select the network type (home, work, or public, if you are on a Windows* device). Choosing the network type will establish a security level appropriate for your location. If you select “home” or “work,” your device will be discoverable to other devices. Be sure to select “public” if you are in a public location like a coffee shop, hotel, restaurant, airport, and other similar locations.

Depending on where you are and the types of hotspots near you, you may be on either an open, unsecured wireless network or a paid/commercial wireless network. You may be asked to sign up for an account or use a paid service like Boingo* or iPass*, which offer various Wi-Fi access plans depending on how much time you plan use the Internet.

Let’s say, though, that you can’t find a Wi-Fi hotspot nearby. Read on to learn how you can use your smartphone as a portable hotspot.

Using Your Smartphone as a Mobile Hotspot

If you’re in a location that doesn’t have a hotspot and you want to connect your laptop to the Internet, you can use your phone as a mobile Wi-Fi hotspot through a process called “tethering.” This allows your laptop to access the Internet and share your smartphone’s data connection.

While the set-up steps vary depending on your smartphone and your Internet service provider, you can usually find the instructions in your phone’s Settings or Manage Connections menu. For security, you’ll want to make sure that you use a Wi-Fi password so that nearby Internet users can’t access your phone or laptop. Also, be aware that tethering your laptop to your phone will use your phone’s data allowance; so be sure to keep an eye on your usage to avoid any overage fees.

Now that you’re connected, that’s it, right? Well, not exactly. You should be aware that while using Wi-Fi hotspots is a convenient way to stay connected with work, family, and friends. Hotspot connectivity also presents some security risks.

Hotspot Security

One of the risks of being connected to the Internet is that the very technologies that help us keep up with our work and personal lives can be vulnerable to hackers and identity thieves.

When looking for a public Wi-Fi hotspot, be sure to connect your smartphone or laptop only to reputable providers—for example, the hotel’s or coffee shop’s wireless network. Be wary about connecting to hotspots that have misspellings such as Bongo instead of Boingo, as hackers sometimes use these seemingly innocent names to lure busy users who aren’t paying close attention.

It’s also possible for hackers to distribute malware (software that can damage or disable your computer) through an unsecured Wi-Fi connection, especially if you are using a file-sharing program over the same network.

Virtual Private Network (VPN)

If you have security concerns about using a public Wi-Fi hotspot, you could consider creating a virtual private network (VPN), which allows you to use to the Internet through an encrypted connection. While this can deter hackers because your data is encrypted, be aware that it will slow down your Internet access because of the processing power required to encrypt and decrypt your transmitted data.

Find a VPN Solution that Works

If you’re interested in using a VPN to safeguard yourself online:

Invest in a monthly service. This is one of the most commonly used solutions. Make sure to do your research before you buy.
Consider purchasing a VPN-enabled router. There are several models on the market that make setting up your own VPN easy.

With more than 9 billion Wi-Fi-enabled mobile devices expected to be in use by the end of the year, the importance of hotspots and Wi-Fi in our lives really can’t be overstated.

The latest imbedded version of mobile networking technology is called 4G (fourth generation), and
the next version (called 5G – fifth generation) is in the early implementation stage. Neither 4G nor 5G have been tested for safety in credible real-life scenarios. Alarmingly, many of the
studies conducted in more benign environments show harmful effects from this radiation. The present article overviews the medical and biological studies that have been performed to date
relative to effects from wireless radiation, and shows why these studies are deficient relative to safety. However, even in the absence of the missing real-life components such as toxic
chemicals and biotoxins (which tend to exacerbate the adverse effects of the wireless radiation), the literature shows there is much valid reason for concern about potential adverse
health effects from both 4G and 5G technology. The studies on wireless radiation health effects reported in the literature should be viewed as extremely conservative, substantially underestimating the adverse impacts of this new technology.

The potential 5G adverse effects derive from the intrinsic nature of the radiation, and its interaction with tissue and target structures. 4G networking technology was associated mainly with carrier frequencies in the range of ~1-2.5 GHz (cell phones, WiFi). The wavelength of 1 GHz radiation is 30 cm, and the penetration depth in human tissue is a few centimeters. In its highest performance (high-band) mode, 5G networking technology is mainly associated with carrier frequencies at least an order of magnitude greater than the 4G frequencies, although, as stated previously, “ELFs (0–3000Hz) are always present in all telecommunication EMFs in the form of pulsing and modulation”.

Penetration depths for the carrier frequency component of high-band 5G wireless radiation will be on the order of a few millimeters. At these wavelengths, one can expect resonance phenomena with small-scale human structures. Additionally, numerical simulations of millimeter-wave radiation resonances with insects showed a general increase in absorbed RF power at and above 6 GHz, in comparison to the absorbed RF power below 6 GHz. A shift of 10% of the incident power density to frequencies above 6 GHz was predicted to lead to an increase in absorbed power between 3–370%.

The common ‘wisdom’ presented in the literature and media is that, if there are adverse impacts resulting from high-band 5G, the main impacts will be focused on near-surface phenomena, such as skin cancer, cataracts, and other skin conditions. However, there is evidence that biological responses to millimeter-wave irradiation can be initiated within the skin, and the subsequent systemic signaling in the skin can result in physiological effects on the nervous system, heart, and immune system.

Additionally, consider the following reference [Zalyubovskaya, 1977]. This is one of many translations of articles produced in the Former Soviet Union on wireless radiation (also, see
reviews of Soviet research on this topic by McRee [1979, 1980], Kositsky [2001], and Glaser and Dodge [1976]). On p. 57 of the pdf link, the article by Zalyubovskaya addresses biological effects of millimeter radiowaves. Zalyubovskaya ran experiments using power fluxes of 10,000,000 microwatts/square meter (the FCC (Federal Communications Commission) guideline limit for the general public today in the USA), and frequencies on the order of 60 GHz.

Not only was skin impacted adversely, but also heart, liver, kidney, spleen tissue as well, and blood and bone marrow properties. These results reinforce the conclusion of Russel (quoted above) that systemic results may occur from millimeter-wave radiation. To re-emphasize, for Zalyubovskaya’s experiments, the incoming signal was unmodulated carrier frequency only, and the experiment was single stressor only. Thus, the expected real-world results (when human beings are impacted, the signals are pulsed and modulated, and there is exposure to many toxic stimuli) would be far more serious and would be initiated at lower (perhaps much lower) wireless radiation power fluxes.

The Zalyubovskaya paper was published in 1977. The referenced version was classified in 1977 by USA authorities and declassified in 2012. What national security concerns caused it (and the other papers in the linked pdf reference) to be classified for 35 years, until declassification in 2012? Other papers on this topic with similar findings were published in the USSR (and the USA) at that time, or even earlier, but many never saw the light of day, both in the USSR and the USA. It appears that the potentially damaging effects of millimeter-wave radiation on the skin (and other major systems in the body) have been recognized for well over forty years, yet today’s discourse only revolves around the possibility of modest potential effects on the skin and perhaps cataracts from millimeter-wave wireless radiation.

Tech evangelists habitually brim with enthusiasm over artificial intelligence’s potential to transform our lives, and the crowds at this year’s Web Summit were no exception.

Here are five uses for AI showcased at one of the world’s largest technology conferences, which returned to Lisbon this week after the 2020 edition was called off due to the pandemic.

Healthcare

When Iker Casillas learned of a start-up that uses AI to better detect irregular heart rhythms, he swiftly signed up as an investor.

The Spanish football legend had suffered a heart attack in 2019, putting a brutal end to his career.

Madrid-based company Idoven analyses data from home heart monitoring kits to track people’s cardiac health — and crucially, to flag up looming problems.

“We are the first company in the world capable of doing it,” its CEO Manuel Marina-Breysse told AFP.

AI is also being used by a growing number of mental health startups.

Woebot, a chatbot which people can use to unburden their anxieties, adapts its responses based on an AI-informed reading of the person’s emotional state.

“If somebody is in distress or they’re really not feeling great, Woebot will invite them to work on it, or just get it off their chest,” explained its founder Alison Darcy, a clinical research psychologist.

Some may find the idea of pouring one’s heart out to a chatbot unnerving, but the Silicon Valley startup points to studies suggesting that people sometimes prefer confiding in a non-judgmental robot.

Cutting waste

AI doesn’t represent a straightforward win for the climate.

Training a single algorithm system can use nearly five times the emissions produced by a car over its lifetime, according to University of Massachusetts researchers.

But AI is also making a wide range of industrial processes more efficient, from cement production to cooling data centres.

It could also be used to reduce the amount of garbage we send to landfill.

British startup Greyparrot uses AI to recognise different types of waste moving down a conveyor belt, picking out recyclables from plastic to glass better than the machines typically used at the moment.

Safer roads

Could AI stop road accidents? Irish startup Provizio is developing technology that uses machine learning to analyse data from sensors attached to a car.

In time, its founder Barry Lunn hopes that will allow emergency braking systems to kick into gear 10 times faster than previously.

Code writing

The age of AI shunning all need for human help, and writing its own computer code, is closer than you may think.

One initiative generating a buzz in Lisbon this week was Copilot, a joint project by software development platform GitHub and research lab OpenAI.

The tool can auto-complete chunks of code, understanding the intentions of the human software engineer.

But New York University researchers suggest the computers still need us: around 40 percent of the time, the code still has bugs in it.

Deepfakes

Recent years have seen growing alarm over deepfake technology, in which stunningly realistic likenesses of living people can be made to act as the creator pleases.

Deepfakes appearing to show actor Tom Cruise went viral this year, prompting fresh questions over whether the technology could be used for fraud or even political manipulation.

Reface, a US startup founded by Ukrainians, wants to use deepfake AI for more playful purposes, allowing the user to swap Justin Bieber’s head, or the Mona Lisa’s, for their own.

But co-founder Ivan Altsybieiev imagines a future where people could mock up entire remakes of their favourite TV shows, starring themselves.

A “future where all content could be personalised”, he told AFP.

]]> Facebook is changing its name – You have to see these suggestions for a new one https://palmacedar.com/blog/facebook-is-changing-its-name-you-have-to-see-these-suggestions-for-a-new-one/?utm_source=rss&utm_medium=rss&utm_campaign=facebook-is-changing-its-name-you-have-to-see-these-suggestions-for-a-new-one Mon, 25 Oct 2021 09:30:31 +0000 https://palmacedar.com/?page_id=11925

Social media giant Facebook has decided it’s time for change — by changing its name. But before you think that you’ll have to log in to some different website, it’s only the name of the company that’s changing, not the name of the social media site.

Think of how Google operates, with a parent company Alphabet and the search engine service is called Google — along with all the other Google-owned services like Gmail and YouTube. There are other examples as well, like the photo-sharing and editing app Snapchat, owned and developed by Snap Inc.

Founder Mark Zuckerberg wants Facebook to be known for more than just its social media platform and wants to focus on building a “metaverse.” That’s a fancy word for the online universe the Big Tech founder sees in his company’s future. The new name hasn’t been revealed yet, but the internet definitely has some suggestions.

What you need to know about Facebook

The shift in direction — and name — will allow Zuckerberg to group all of Facebook’s products and services together under one main entity. Together with WhatsApp, Instagram and Oculus, Facebook will eventually only refer to the social media platform.

We won’t have to wait too long to hear the new name. Rumor has it Zuckerberg will announce it later this month during Facebook’s annual augmented reality and virtual reality conference.

There’s speculation it could happen sooner, though. And with no indication on what it will be called, online users had plenty of suggestions.

Novelist and playwright Paul Rudnick had some choice suggestions for Zuckerberg, which included Facebook ‘N Things, Facebook Zero and That Thing Your Mom Loves.

Facebook is rumored to be changing its name to become a larger brand. Possibilities:
1) I Can’t Believe It’s Not Facebook
2) Mark’s Mart
3) Facebook ‘N Things
4) Friendster+
5) Facebook Zero
6) Facebook NCIS
7) Markwarts
8) That Thing Your Mom Loves

The replies to his tweet naturally elicited more suggestions from his followers. A few of our favorites:

2 facebook 2 furious
How I Met My Stalker
Mark’s Space
Platform formerly known as Facebook
Faceplant
Data Hoover
MySpaceBook

Here are some more suggestions from Twitter users. Some are excellent plays on words, others are tongue in cheek and the rest are just plain funny.

Faceverse
Metabook
FaceXR
Metaplace
Instaverse
Facespace
MetaFacial
Spatialbook
FBXR
Virtualface
FloatingHeadlandia
Zuckaverse

Dear Facebook:

We’ve received your request to change your name. However, due to our real names policy, you will first need to fax us a copy of your court order and new driver’s license….

— Ina Fried (@inafried) October 20, 2021

In a July interview, Zuckerberg outlined the new direction the company will take. “We will effectively transition from people seeing us as primarily being a social media company to being a metaverse company,” he told The Verge, indicating the process will happen over a few years. To achieve this goal, the company is looking to hire as many as 10,000 new employees.

Wait, tell me more about the metaverse.

Think of the metaverse this way: You slip on a headset and you’re connected to infinite digital worlds that you can use for anything. Meet up for digital concerts, sit in a virtual office with your remote coworkers or explore faraway destinations you can’t travel to in real life.

You’ll need a 3D avatar, or a representation of yourself. And you’ll need the right gear, namely a VR headset.

Facebook is pouring millions of dollars into developing the metaverse. Specifically, it’s working on VR apps for both social hangouts and the workplace. This could revolutionize the world of advertisements, too.

Epic Games, which makes Fortnite, already hosts concerts and events inside its digital world. CEO Tim Sweeney says eventually you could use the metaverse to test-drive new cars from the comfort of your own home. Imagine that.

Don’t get too excited yet. The metaverse may take another 10 or 15 years to build.

10 useful tech tips you’ll use over and over. Everybody loves a cool trick such as phone case cleaning tips, . No matter how well we know an app or program, there’s almost always some shortcut we never learned. The same goes for hardware: We may use gadgets every day without knowing their helpful quirks.

10 Useful Tech Tips You will Use Over And Over.

Here are some of my favorite popular tech tips, tricks, and shortcuts for a range of popular programs and tools:

1. Put your USB drive in the right way the first time

Plugging in a USB cable the right way feels like a no-brainer. Then why do we get it wrong on the first try so often?

Here’s the secret: Grab any USB cable sitting around your house. See that symbol on one side? It’s not just branding or decoration. That symbol will point up if you’re plugging in horizontally and if you’re plugging a cable vertically, the USB symbol will face you. Now you know.

2. Reopen a closed browser tab

It happens all the time. You have a dozen tabs open in your browser and accidentally close the wrong one. You could open up your browser’s history and reopen the tab from there, or you can do it with a couple of keystrokes.

Hit Ctrl+Shift+T on your PC or Command+Shift+T on your Mac to automatically reopen the tab you just closed.

3. Share a YouTube video at a precise point

If you see something in a YouTube video that you want to share at a particular point, you can get a link that takes people directly to that moment, you can get a link that takes people directly to that moment. Click the Share button below the video. Look for a checkbox below the link. It will automatically display the time at which you currently have the video stopped.

You can stick with this time or choose a different time. Copy the link and share it on your preferred social media or email it to a friend. When someone views the link, the YouTube video will automatically skip right to the point you chose.

4. Search using “Site:” to find content like a ninja

A Google search can return millions of results. Cut that down significantly by searching just a single site with Google’s Site: feature. Open Google in your browser and type “site:” and then the website you wish to search. Like this: “site:komando.com” but leave off the quotation marks.

Tip in a tip: You can enter “site:komando.com search term” in your browser’s address bar and no need to go to Google. Again, no quotation marks needed.

5. Report junk texts and stick it to the scammers

Junk texts are downright annoying. You can block them, but it feels good to take action, too.

Report texts to the GSMA’s Reporting Service with just a few clicks. Forward the message to 7726 (guess what that spells?) or just hit “Report junk” in your messaging app.

6. Use your voice in Google Docs

I bet you already use your phone’s speech-to-text to dictate text messages or even emails, but did you know you can do the same in Google Docs? It’s free and it works surprisingly well.

Open a new document in Google Docs, then enable Voice Typing from the Tools menu. Then start dictating. Voice Typing recognizes commands like “comma,” “period,” and “new paragraph” as well.

7. Download movies on Disney Plus

Each streaming service has a different policy for downloading video content and watching offline. Netflix was a major holdout until 2016. But Disney Plus allowed this option right away. The download icon is located at the bottom of the menu. Using the Disney Plus app, you can also download as many titles as your hard drive can hold.

8. Crop a screenshot

Screenshots are common practice, but you often capture more than you need. Revealing too much of your screen in a single image can actually threaten your security. Instead, you can take a screenshot with precise cropping, so that you include only what you want.

On a Mac, press Command + Shift + 5, and a rectangle will emerge, which you can manipulate as much as you want.

On Windows 10, go to Start, enter the Search Bar, and type Snipping Tool. This will give you a similar box that you can drag to any shape over your screen.

9. Search WhatsApp chats

Messages accumulate over time, no matter what platform you use. We want to find that one hilarious quote or a vital street address, but it’s lost in a disjointed sea. WhatsApp may be the most-downloaded app of the decade, but many users are unaware that you can search your messages, just like Google.

For iOS versions, there’s a search bar; for Android, there’s a search icon. Either way, find words unique to a specific conversation to narrow down the exact message you’re looking for.

10. Unsend an email

Did you just send out an email to everyone that was meant for one person? Well, Gmail has the ability to unsend an email by adjusting one setting prior to writing your email.

This recall of a message will also allow you to modify spelling errors, incorrect recipients, subject line and even append forgotten attachments.

Be sure to adjust the setting to a higher number than the default setting of five seconds. Let’s face it; five seconds isn’t even enough to realize you made an error, let alone hit the unsend button. Thankfully, Gmail settings provide the option of pausing an email delivery up to 30 seconds.

Bonus Tip: How to electronically sign a PDF

PDFs are already starting to replace paper documents in many offices across the country. They’re more flexible, portable and convenient to use – but not everyone knows you can sign a PDF document just like a physical one.

Nearly every PDF-reading application features some way to electronically sign documents and forms.

]]> Microsoft’s New Slim Pen 2 With Haptics https://palmacedar.com/blog/microsofts-new-slim-pen-2-with-haptics/?utm_source=rss&utm_medium=rss&utm_campaign=microsofts-new-slim-pen-2-with-haptics Mon, 04 Oct 2021 12:09:21 +0000 https://palmacedar.com/?page_id=11838

Microsoft has refreshed its Slim Pen to magnetically fit into the Surface Pro 8’s keyboard. Notably, the Slim Pen 2 has a custom chip called Microsoft G6 and haptic functionality that aims to make writing and drawing feel more realistic. Microsoft says that it’s extending the haptic tech to work in several apps, and it showcased the stylus being used in Adobe Photoshop. The artist on display claimed that its sharper tip makes it easier to use and more responsive. It can work with every product announced today, including the Surface Pro 8, the Surface Go 3, the Pro X, and the Surface Duo 2 via its pen cover. It can attach magnetically to the side of the new Surface Laptop Studio.

Microsoft says the Slim Pen 2 offers increased accuracy and “incredible” shading. The most notable new feature in the $129.99 Slim Pen 2 is the haptic functionality that aims to make writing and drawing feel more realistic. Additionally, the hardware feature can send tactile signals when you use gestures in supported apps. In Microsoft Word, for example, you’ll feel a vibration when you’ve scribbled through a word to delete, or circled text to select or highlight it. We’ll see how widely this is adopted soon enough, but regardless, it’s a good idea — especially from an accessibility standpoint.

This clever haptic feature will only work on select devices, including the new Surface Pro 8 and Surface Laptop Studio that run Windows 11. Though, it’s compatible with a wide range of Surface devices old and new, as well as devices that support the Microsoft Pen Protocol (MPP).

Here’s the full list of compatible products:

Surface Laptop Studio
Surface Pro 3 to Pro 8
Surface Pro X
Surface Duo, Duo 2
Surface Go, Surface Go 2, Surface Go 3
Surface Hub 2S
Surface Laptop 1 to 4
Surface Studio 1, 2
Surface Book 1 to 3
Non-Surface devices that support Microsoft Pen Protocol (MPP)

The Slim Pen 2 supports Bluetooth 5.0, and Microsoft says that it can last up to 15 hours per charge. As for how it charges, there are multiple ways. There will be a charger that’s sold separately, and the Slim Pen 1 USB-C charging base will soon receive an update to be able to charge this new one. In addition, it can charge wirelessly while magnetically attached to the Surface Pro Signature Keyboard, to the side of the Surface Laptop Studio, or with the Surface Duo 2’s pen cover. Microsoft says the Surface Slim Pen 2 is available for preorder starting today for $129.99.

]]> Microsoft unveils Windows 11 operating system https://palmacedar.com/blog/microsoft-unveils-windows-11-operating-system/?utm_source=rss&utm_medium=rss&utm_campaign=microsoft-unveils-windows-11-operating-system Mon, 04 Oct 2021 11:40:05 +0000 https://palmacedar.com/?page_id=11863

Microsoft had on Tuesday, the 31^st of August 2021 intimated the public its plans to roll out Windows 11 on the 5^th of October 2021, in a free upgrade of its operating system available for hardware that works with Windows 11 pre-loaded and other eligible Window 10 personal computers.

The new software will let Android apps run on the Windows desktop.

Product manager Panos Panay promised smaller, faster security updates – a common complaint for Windows users – and said they would happen in the background.

Windows 11 will also let users configure multiple desktops for work, home, and gaming, like on a Mac.

One cosmetic change is putting the “Start” button at the bottom-centre of the screen rather than left-hand side.

Microsoft says there are currently about 1.3 billion devices running Windows 10.

An early preview version of the new system will be released for app developers next week.

Windows 11 will be available as a free update to existing Windows 10 users – although some devices will not have the right specifications. These include a minimum of 64 gigabytes of storage and 4 gigabytes of RAM.

“We expect all eligible devices to be offered the free upgrade to Windows 11 by mid-2022. If you have a Windows 10 PC that’s eligible for the upgrade, Windows Update will let you know when it’s available,” says Panos Panay.

Here are 11 highlights of this release

The new design and sounds are modern, fresh, clean and beautiful, bringing you a sense of calm and ease.
With Start, we’ve put you and your content at the center. Start utilizes the power of the cloud and Microsoft 365 to show you your recent files no matter what device you were viewing them on.
Snap Layouts, Snap Groups and Desktops provide an even more powerful way to multitask and optimize your screen real estate.
Chat from Microsoft Teams integrated into the taskbar provides a faster way to connect to the people you care about.
Widgets, a new personalized feed powered by AI, provides a faster way to access the information you care about, and with Microsoft Edge’s world class performance, speed and productivity features you can get more done on the web.
Windows 11 delivers the best Windows ever for gaming and unlocks the full potential of your system’s hardware with technology like DirectX12 Ultimate, DirectStorage and Auto HDR. With Xbox Game Pass for PC or Ultimate you get access to over 100 high-quality PC games to play on Windows 11 for one low monthly price. (Xbox Game Pass sold separately.)
Windows 11 comes with a new Microsoft Store rebuilt with an all-new design making it easier to search and discover your favorite apps, games, shows, and movies in one trusted location. We look forward to continuing our journey to bring Android apps to Windows 11 and the Microsoft Store through our collaboration with Amazon and Intel; this will start with a preview for Windows Insiders over the coming months.
Windows 11 is the most inclusively designed version of Windows with new accessibility improvements that were built for and by people with disabilities.
Windows 11 unlocks new opportunities for developers and creators. We are opening the Store to allow more developers and independent software vendors (ISVs) to bring their apps to the Store, improving native and web app development with new developer tools, and making it easier for you to refresh the look and feel across all our app designs and experiences.
Windows 11 is optimized for speed, efficiency and improved experiences with touch, digital pen and voice input.
Windows 11 is the operating system for hybrid work, delivering new experiences that work how you work, are secure by design, and easy and familiar for IT to deploy and manage. Businesses can also test Windows 11 in preview today in Azure Virtual Desktop, or at general availability by experiencing Windows 11 in the new Windows 365.
