With the latest update, the Apple Watch has a built-in sleep tracker to monitor and record your sleeping patterns. Here’s how to use it.
Insomnia is a common problem, especially these days with worries about the coronavirus, politics, and the economy. A lack of sufficient sleep can affect not just your personal life but your professional one. It’s difficult to concentrate on work and be productive without a healthy and consistent number of hours of sleep each night. But how can you tell the amount of sleep you’re actually getting?

As you wear your watch at night, the tracker records the actual time you’re asleep and how much total sleep you get. The next morning, the Sleep app shows you the periods of sleep time during the night and keeps a daily and weekly record of your sleep pattern. Here’s how it works.
Sleep tracking on an Apple Watch requires a Series 3, 4, 5, or 6 with watchOS 7 or higher, and an iPhone 6S or later with iOS 14 or higher. Confirm those requirements. Open the Watch app on your phone. Make sure you’re in the My Watch section and tap the entry for Sleep where you can set up different options.
- The first option for Turn On Automatically simplifies your Lock screen and turns on Do Not Disturb mode so you can wind down before bedtime.
- The second option for Show Time turns off the display of the date and time during sleeping hours.
- The third option for Track Sleep with Apple Watch tells your watch to monitor your sleep.
- The fourth option for Charging Reminders tells you when your watch is fully charged before bedtime.
Turn on all of the switches to enable these options (Figure A).
Next, tap the link to Open Sleep Options to go to the Health app. Turn on the switch for Sleep Schedule. Tap the Edit link under Full Schedule and set the regular times you go to sleep and wake up. You can set different times for different days, for example, one for weekdays and another for weekends.
Under Additional Details, select the entry for Sleep Goal to set the number of hours and minutes for which you’d like to be asleep.
- Select the entry for Wind Down to determine the amount of time for winding down before sleep.
- Select the entry for Wind Down Shortcuts to set up any shortcuts you’d like to apply during Wind Down time.
- Select the entry for Options to confirm the options you set in the Sleep app and to set up additional ones (Figure B).
Open the Sleep app on your watch and select the schedule. At the next screen, tap the Wake Up time if you need to change it. Turn on an alarm if you require one to wake you up at the right time. Select the time for Bedtime to change that as well.
Return to the main screen. Select Full Schedule to turn off your Sleep Schedule for any specific nights or all nights. You can also add a schedule and change your sleep goal or Wind Down time. Make sure your watch is sufficiently charged to last the night and then wear your watch to bed (Figure C).
The next morning, check the Sleep app on your watch to see how much sleep you got. Then open the Health app on your iPhone for more details. Go to the Browse screen and select the entry for Sleep. The bar graphs display your start and end times for sleep. As you record multiple nights of sleep, the data will reveal your history on a weekly or monthly basis.
Select the bar for a specific day to see the total amount of time you were asleep. Select the entry to Show More Sleep Data. Here, you can see how many nights of sleep were measured, your sleep goal, your average time in bed, and your average time asleep (Figure D).
Open source magic solves a months-long problem in 20 minutes
Commentary: Capventis and other system integrators increasingly depend on open source to help them solve critical enterprise IT issues.
As more enterprises lurch towards digital transformation and cloud-native architectures, accelerated by the urgency of business changes during the COVID pandemic, many depend on systems integrators (SIs) for help. If you look under the hood of most successful digital initiatives created by SIs (or any company), you’ll find the engine involves a great deal of open source software (up to 90%, according to Sonatype data).
This rush towards digital transformation preceded the pandemic, of course, as enterprises also saw the need to move faster in their markets and accelerate the introduction of new technologies. But SIs have become key partners in driving open source deeper into enterprise IT, with projects like GraphDB increasingly important to solve data integration issues. Capventis offers a good example of how this works.

Every industry is trying to get to the future as fast as possible, and telecommunications is no different. As Iain Morris called out in a Light Reading article, in 2018 France’s Orange estimated that a third of its global workforce–more than 50,000 employees–needed reskilling if the company hoped to keep up with cloud vendors. In that same article, Morris pointed out that Spain’s Telefonica figured it would need nearly $2 billion in staff training and early retirement buyouts to bring in new talent with new skills to be competitive.
Such telcos often turn to SIs, like UK-based Capventis, who in turn bring domain expertise and work primarily with clients in the Business Intelligence (BI), Customer Relationship Management (CRM), and Customer Experience (CX) fields. These areas haven’t traditionally been ripe for open source, but even SIs with these focus areas rely on open source software to help their clients. It’s hard for even the best proprietary software vendors to keep pace with the innovation cycles of successful open source projects; so, these SIs will partner with companies like Alteryx, Qlik, Qualtrics, and Zendesk, augmenting their proprietary software with open source expertise.
In the case of Capventis, a big part of its projects involves pulling vast quantities of legacy and real-time data for its clients. It reminds me of a conversation from a decade ago with MuleSoft creator Ross Mason, who had started his career with an SI. He created MuleSoft (then called MuleSource) as something like an enterprise service bus to move lots of data around and connect it to an application or service. He kept having to do the same thing–moving lots of data–over and over for his clients, and he described it as “donkey work.” So he wrote MuleSource, which eventually ended up being acquired by Salesforce for more than $6 billion.
Today, Capventis faces the same challenges but at a larger scale, as data volume, variety, and velocity grow exponentially. “A client might have Zendesk for tickets and rely on Qualtrics for surveys,” said Mike Hawkes, CTO of Capventis. “But they all rest on a giant old Oracle database. There are typically many legacy systems that need to interact but none have a connector. And those that do have connectors don’t handle maintaining integrity between various systems.”
Capventis wrote its own data stack to manage this variety of data and integrations, giving it the appropriate name of Glü. But the company also needed some open source magic.
Integrating data the open source way
Across its client base, Capventis increasingly faced challenges with the limitations of SQL in scale-out, integration projects using legacy SQL databases with tabular structures that required large numbers of joins to integrate disparate data sources. After Capventis won a major UK government project, it struggled with how to integrate several older, proprietary databases that were still in production and being regularly updated with new information. The database project involved multiple departments that over time had merged and separated and merged again. What should have been a dozen tables had exploded into more than 300. The legacy database providers refused to collaborate on the project.

Stymied, Capventis reached into its open source software bag of tricks. Based on the scale and scope of the project, the team wanted a GraphQL-based interface with a flexible, reliable, and high-performance graph database on the backend.
For this project, Capventis selected GraphDB from Dgraph Labs after an internal technology bake-off. Dgraph outperformed the others and had the added advantage of a global developer community that the company found to be responsive and friendly. (I’ve written about Dgraph before.) The Capventis team used Dgraph to convert all the legacy data from multiple sources and cleansed it on the fly with no data loss, while simultaneously generating a schema read for immediate queries.
“We linked Glü to their database servers, fetched all the data, and threw it into Dgraph,” Hawkes said. “Within 20 minutes we had the entire structure of the data set with all the proper interactions captured in Dgraph. We solved this problem in one hit. It was months in the planning and minutes in the execution.”
That’s the power of open source.

Diamonds may help measuring thermal conductivity in living cells
Scientists have very precise instruments, but measuring properties of tiny little cells is still very difficult. Now researchers at the University of Queensland have developed a new tool to measure heat transfer inside living cells. It includes actual diamonds and it can work as both a heater and a thermometre. Someday it can improve cancer diagnosis.
Cancer cells are different – they behave differently and exhibit different properties. Scientists have long speculated that in some cases precisely targeted thermal therapies could be very effective against cancer. However, in order for this to become reality scientists needed to know thermal conductivity of living cells. With current technology it is literally impossible to measure thermal conductivity – the rate that heat can flow through an object if one side is hot and another is cold – inside of such tiny living things as cells.
Scientists from Australia, Japan and Singapore now employed nanodiamonds (just tiny little diamonds) to act as minute sensors in a new system. Diamonds are great, because they are very hard and because they are just a different form of carbon, which is very well-known to us. Scientists coated their nanodiamonds with a special heat-releasing polymer. This resulted in a sensor, which can act as a heater or a thermometre, depending on what kind of laser light is applied. This sensor allows measuring thermal conductivity in living cells with a resolution of 200 nanometres.
Associate Professor Taras Plakhotnik, lead author of the study, said that this new method already revealed some new interesting information about cells. He said: “We found that the rate of heat diffusion in cells, as measured in our experiments, was several times slower than in pure water, for example.”
If cancer cells and healthy cells exhibit different thermal conductivity, this kind of measurement could become a very precise diagnostic technique. Also, because these particles are not toxic and can be used in living cells, scientists think they could open the door for improving heat-based treatments for cancer. Measuring head conductivity could help monitor biochemical reactions in real time in the cell. But that’s not all. Scientists think that this method could lead to a better understanding of metabolic disorders, such as obesity.
Diamonds are commonly used in science and industry. People oftentimes see them as something from the jewelry world, but they are much more common elsewhere. And they are not even that expensive. Hopefully, this study will result in a new method to research living cells and maybe some novel therapies as well.

Redmi Note 10 Launch Teased Officially After Rumours Tipping February Debut in India
Redmi Note 10 launch has been officially teased on Weibo. The new development comes just weeks after the rumour mill suggested the existence of the Redmi Note 10 series that could include the Redmi Note 10, the Redmi Note 10 Pro, and the Redmi Note 10 Pro 5G. The new series is expected to succeed the Redmi Note 9 family that debuted with the launch of the Redmi Note 9 Pro and the Redmi Note 9 Pro Max in India in March last year.
Redmi General Manager Lu Weibing has teased the launch of the Redmi Note 10 on Weibo. Instead of giving away details of the phone directly, Weibing has posted an image of the Redmi Note 9 4G asking users about their expectations with the Redmi Note 10.
The Redmi Note 10 is speculated to launch in India alongside the Redmi Note 10 Pro in February. Both phones will be priced aggressively, according to tipster Ishan Agarwal. The Redmi Note 10 in the series is tipped to come in Gray, Green, and White colour options.
Although Xiaomi hasn’t provided any specifics about the phone yet, the Redmi Note 10 Pro 5G purportedly received a certification from the Bureau of Indian Standards (BIS) earlier this month. The phone is also said to have surfaced on the US
Federal Communications Commission (FCC) website with the model number M2101K6G. It has also reportedly appeared on the websites of other regulatory bodies including the European Economic Commission (EEC), Singapore’s IMDA, and Malaysia’s MCMC.
Redmi Note 10 series specifications (expected)
The Redmi Note 10 Pro is rumoured to come with a 120Hz display and include the Qualcomm Snapdragon 732G SoC. However, the 5G variant of the Redmi Note 10 Pro is said to come with the Snapdragon 750G SoC. It is speculated to have 6GB and 8GB RAM options as well as 64GB and 128GB storage versions. The Redmi Note 10 Pro models will come with a 64-megapixel primary camera sensor and include a 5,050mAh battery, according to a recent report.
Similar to the Redmi Note 10 Pro models, the Redmi Note 10 is also rumoured to have both 4G and 5G versions. The smartphone is tipped to have a 48-megapixel primary camera sensor and include a 6,000mAh battery.
The Redmi Note 10 Pro and the Redmi Note 10 are both expected to run on Android 11 with MIUI 12 out-of-the-box.
