Chapter marking within podcasts

Android main interactive lock screen

Smartphones are facilitating our listenership to podcasts

As we listen to more spoken-word audio content in the form of podcasts and the like, we may want to see this kind of audio content easily delineated in a logical manner. For that matter, such content is being listened to as we drive or walk thanks to the existence of car and personal audio equipment including, nowadays, the “do-it-all” smartphones being connected to headphones or car stereos.

This may be to return to the start of a segment if we were interrupted so we really know where we are contextually. Or it could be to go to a particular “article” in a magazine-style podcast if we are after just that article.

Prior attempts to delineate spoken-word content

In-band cue marking on cassette

Some people who distributed cassette-based magazine-style audio content, typically to vision-impaired people, used mixed-in audio marking recorded at high speed to allow a user to find articles on a tape.

This worked with tape players equipped with cue and review functionality, something that was inconsistently available. Such functionality, typically activated when you held down the fast-forward or rewind buttons while the tape player was in play mode, allowed the tape to be ran forward or backward at high speed while you were able to hear what’s recorded but in a high-pitch warbling tone.

With this indexing approach, you would hear a reference tone that delineated the start of the segment in either direction. But if you used the “cue” button to seek through the tape, you would also hear an intelligible phrase that identified the segment so you knew where you were.

Here, this function was dependent on whether the tape player had cue and review operation and required the user to hold down the fast-wind buttons for it to be effective. This ruled out use within car-audio setups that required the use of locking fast-wind controls for safe operation.

Index Marking on CDs

The original CD Audio standard had inherent support for index marking that was subordinate to the track markers typically used to delineate the different songs or pieces. This was to delineate segments within a track such as variations within a classical piece.

Most 1980s-era CD players of the type that connected to your hi-fi system supported this functionality. This was more so with premium-level models and how they treated this function was markedly different. The most basic implementation of this feature was to show the index number on the display after the track number. CD players with eight-digit displays showed the index number as a smaller-sized number after the track number while those with a four or six-digit display had you press the display button to show the track number and index number.

Better implementations had the ability to step between the index marks with this capability typically represented by an extra pair of buttons on the player’s control surface labelled “INDEX”. Some more sophisticated CD players even had direct access to particular index numbers within a track or could allow you to program an index number within a track as part of a user-programmed playlist.

As well, some CDs, usually classical-music discs which feature long instrumental works that are best directly referenced at significant points made use of this feature. Support for this feature died out by the 1990s with this feature focused on marking the proper start of a song. It was considered of importance with live recordings or concept albums where a song or instrumental piece would segue in to another one. This was of importance for the proper implementation of repeat, random (shuffle) play or programmed-play modes so that the song or piece comes in at the proper start.

There was an interest in spoken-word material on CD through the late 1990s with the increase in the number of car CD players installed in cars. This was typically in the form of popular audiobooks or foreign-language courseware and car trips were considered a favourite location for listening to such content. But these spoken-word CDs were limited to using tracks to delineate chapters in a book or lessons within a foreign-language course.

But CD-R with the ability to support on-site short-run replication of limited-appeal content opened the door for content like religious sermons or talks to appear on the CD format. This technology effectively “missed the boat” when it came to support for index marking and most CD-burning software didn’t allow you to place index marks within a track.

The podcast revolution

File-based digital audio and the Internet opened the door to regularly-delivered spoken-word audio content in the form of podcasts. These are effectively a radio show that is in an audio file available to download. They even use RSS Webfeeds to allow listeners to follow podcasts for newer episodes.

Here, podcast-management or media-management software automatically downloads or enqueues podcast episodes for subsequent listening, marking what is listened to as “listened”. Some NAS-based DLNA servers can be set up to follow podcasts and download them to the NAS hard disk as new content, creating a UPnP-AV/DLNA content tree out of these podcasts available to any DLNA-compliant media playback device.

The podcast has gained a strong appeal with small-time content creators who want to create what is effectively their own radio shows without being encumbered by the rules and regulations of broadcasting or having to see radio stations as content gatekeepers.

The podcast has also appealed to radio stations in two different ways. Firstly, it has allowed the station’s talent to have their spoken-word content they broadcast previously available for listeners to hear again at a later time.

It also meant that the station’s talent could create supplementary audio content that isn’t normally broadcast but available for their audience, thus pushing their brand and that of the station further. This includes the creation of frequently-published short-form “snack-sized” content that may allow for listening during short journeys for example.

Secondly a talk-based radio station could approach a podcaster and offer to syndicate their podcast. That is to pay for the right to broadcast the podcast on their radio station in to the station’s market. It would appeal to radio stations having programming that fills in schedule gaps like the overnight “graveyard shift”, weekends or summer holidays while their regular talent base isn’t available. But it can also be used as a way to put a rising podcast star “on the map” before considering whether to have them behind the station’s microphone.

Why chapter marking within podcasts?

A lot of podcast authors typically ran their shows in a magazine form, perhaps with multiple articles or segments within the same podcast. As well, whenever one gave a talk or sermon, they would typically break it down in to points to make it clear to their audience to know where they are. But the idea of delineating within an audio file hasn’t been properly worked out.

This can benefit listeners who are after a particular segment especially within a magazine-style podcast. Or a listener could head back to the start of a logical point in the podcast when they resume listening so they effectively know where they are at contextually.

This can also appeal to ad-supported podcast directories like Spotify who use radio-style audio advertising and want to insert ads between articles or sections of a podcast. The same applies to radio stations who wish to syndicate podcasts. Here they would need to pause podcasts to insert local time and station-identity calls and, in some cases, local advertising spots or news bulletins.

Is this feasible?

The ID3 2 standard which carries metadata for most audio file formats including MP3, AAC and FLAC supports chapter marking within the audio file. It is based around a file-level “table of contents” which determine each audio chapter and can even have textual and graphical descriptions for each chapter.

There is also support for hierarchical table of contents like a list of “points” within each content segment as well as an overall list of content segments. Each of the “table of contents” has a bit that can indicate whether to have each chapter in that “table of contents” played in order or whether they can be played individually. That could be used by an ad-supported podcast directory or broadcast playout program to insert local advertising between entries or not.

What is holding it back?

The main problem with utilising the chapter markers supported within ID3.2 is the lack of proper software support both at the authoring and playback ends of the equation.

Authoring software available to the average podcaster provides inconsistent and non-intuitive support for placing chapter markers within a podcast. This opens up room for errors when authoring that podcast and enabling chapter marking therein.

As well, very few podcast manager and media player programs recognise these chapter markers and provide the necessary navigation functionality. This could be offered at least by having chapter locations visible as tick marks on the seek-bar in the software’s user interface and, perhaps allowing you to hold-down the cue and review buttons to search at the previous or next chapter.

Better user interfaces could list out chapters within a podcast so users can know “what they are up to” while listening or to be able to head to the segment that matters in that magazine-style podcast.

Similarly, the podcast scene needs to know the benefits of chapter-marking a podcast. In an elementary form, marking out a TED Talk, church sermon or similar speech at each key point can be beneficial. For example, a listener could simply recap a point they missed due to being distracted thus getting more value out of that talk. If the podcast has a “magazine” approach with multiple segments, the listener may choose to head to a particular segment that interests them.

Conclusion

The use of chapter marking within podcasts and other spoken-word audio content could make this kind of content easier to deal with for most listeners. Here, it is more about searching for a particular segment within the podcast or beading back to the start of a significant point therein if you were interrupted so you can hear that point in context.

Arm Cortex-A78C CPU: Secure and scalable performance for next-generation on-the-go devices (Blog Post)

My Comments

With some computer manufacturers offering regular computers that use ARM microarchitecture, there had to be a time for ARM Holdings to introduce a performance variety of their RISC-based computer chipset design.

This is in the form of the Cortex A78C CPU design number which is increased performance over current ARM-based CPU designs used in some Chromebooks or the Always Connected PC that runs Windows 10. It is being seen as an upgrade path for use cases with these systems where increased performance is being desired like games or multimedia.

This will give Always Connected PCs that run Windows on ARM silicon more credibility

This is not really about clawing back the position that RISC-based microarchitecture held during the late 80s and early 90s as having increased multimedia prowess, even though this was facilitated with Motorola silicon. Rather this chip design is about blending performance and power efficiency making it appeal to a performance class of highly-portable computing device. Think of devices like the Always Connected PC notebook or Chromebook computer, a mobile-platform tablet with gaming or advanced multimedia prowess or a handheld gaming console.

Here the idea may be to keep the same battery type and thermal design for the device in question but allow more performance out of that device. This will be very similar what happened with portable audio equipment through the 1970s where manufacturers improved on the device’s design while keeping the power-supply requirement the same across the years for the device class. This led to amplifier and speaker designs that could allow for increased sound quality that led to increased product differentiation and improvement.

But where do I see this taking place for something like an Always Connected PC laptop that runs Windows 10 on ARM, or an ARM-based Chromebook or even a mobile-platform tablet? I would see this come about in the form of product differentiation in the context of CPU-level performance where manufacturers can offer device models that factor in performance. This avoids computers in the Always Connected PC or Chromebook class being relegated to “baseline duty machines” and allow them to be on a par with traditional Windows 64-bit x86-based computers when it comes to gaming or multimedia.

The same also holds true for mobile-platform tablets of the same ilk as the iPad or Samsung Galaxy Tab S. Here, it could be feasible for manufacturers to open up interest in gaming or multimedia-focused Android tablets that are about performance. That is especially where a tablet’s larger display surface can make it appeal as a gaming companion device to a smartphone.

Let’s not forget companies like Nintendo who have a strong legacy with the handheld games consoles from its Game & Watch devices of the early 80s through the Game Boy devices of the 1990s to the current Nintendo Switch. Here, they could work towards more powerful iterations of their current platforms, whether you consider them as a “timewaster” or a “guilty pleasure”. These platforms could even show some more highly-capable games as well while even using higher-resolution displays.

What will need to happen is for the likes of Qualcomm and Samsung to build this design into the actual CPU processors in order to have it appear in newer computer devices. As well, Microsoft would have to encourage the creation of games and similar software for ARM-based Windows setups especially those that use more powerful silicon.

This could then place ARM-based and x86-based mobile computing on a par with each other when it comes to performance but allow ARM to gain the edge in power efficiency for portable use cases.

My Comments

Acer is about to offer 14” laptop computers focused towards the business community that use Intel’s Tiger Lake silicon with Xe graphics. These come primarily in the form of the TravelMate P4 clamshell laptop and the TravelMate Spin P4 convertible laptop. The latter model is intended to snap at the heels of Lenovo’s ThinkPad X1 Yoga convertible business laptop.

.. also in a convertible 2-in-1 form as the Acer TravelMate Spin P4

Both these computers have as a baseline option, Thunderbolt 4 connectivity along with other business-grade connectivity requirements. For wireless connectivity, they will have Wi-Fi 6 and Bluetooth 5 as standard. But there is the ability to have them specified with an LTE mobile broadband modem that uses eSIM service authentication.

As far as graphics go, these computers will use the Intel Xe integrated graphics processors that can do the job for 1080p gaming or for basic content creation tasks. There is the option for users to specify an NVIDIA MX350 mobile discrete graphics processor if they want a bit more graphics “pep”. Of course that will have the NVIDIA Optimus automatic graphics-processor switchover so the Intel Xe integrated GPU can work as a highly-capable “lean-burn” option for battery use. But, as I have mentioned before, these have a Thunderbolt 4 connection which will offer connectivity to external graphics modules as another path to improve your computer’s graphics performance.

Both computers are designed to be highly-durable and comply with MIL-STD-810G durability standards. There is also essential security security features including the TPM 2.0 security processor which works in a discrete form, fingerprint reader and camera fit for Windows Hello facial recognition.  The camera even has a privacy shutter so you aren’t easily spied upon.

The TravelMate P4 will start from USD$899 or EUR€899 while the TravelMate Spin P4 will start from USD$999.99 or EUR€999. But with Acer’s TravelMate business computer range like with the Lenovo ThinkPad / ThinkCentre business computer range, they don’t focus it necessarily towards particular business use cases, be it the small-business operator or freelancer who manages the computer by themselves as their own “axe”, or an enterprise who buys and manages a large fleet of computers for staff to use.

With Acer offering these TravelMate business laptops that run the Intel Tiger Lake silicon with highly-capable Xe graphics processors, it could really define what is expected on the outset for an all-round computer. It means being able to do some advanced graphics tasks like modest gameplay or basic photo and video editing. These business laptops could also be a sign of things to come for mainstream consumer laptop product ranges.

Trying to reduce the number of USB chargers around the house. What can you do?

Belkin BOOST Charge 68W GaN Dual USB-C Wall Charger (Australasia) product picture courtesy of Belkin

You may need to end up rationalising the number of USB chargers you have in your home

You can easily end up with too many USB wall chargers in your home. This can happen as you purchase more devices that come with these chargers or you find and use better chargers like multi-outlet “charging bars”.

Then you think of rationalising the number of chargers you have on hand in your home as you find you have too many of them. But how can you go about this effectively without sacrificing convenience?

Here, the idea is to keep enough chargers on hand and in appropriate locations that assures you of convenience. No-one wants to find that they can’t power or charge their devices because there aren’t enough of these chargers available near to them for their needs.

Which charges do you keep.

Firstly, you need to retain chargers that have at least one USB Type-A socket and/or USB Type-C socket on the charger unit itself. That means you don’t really need chargers that have a USB micro-B or Apple MFi Lightning plug on the end of a cable wired to the charger itself.

This will mean that you can use them to charge any device as long as you have a connection cable with the appropriate connectors on each end. You can even consider the use of longer cables for more flexible connectivity setups.

As well, prefer to keep powerful chargers or those that implement USB Power Delivery for USB Type-C units or Qualcomm fast-charge standards (for USB Type-A units. This will mean that you can quickly charge up your phone or tablet or allow them to work in a high-performance setting while connected to AC power.

Keeping one or more USB-C chargers that use USB Power Delivery and can put up at least 60 watts to at least one USB-C port is a good direction to go. This is important when you are using or intend to purchase an ultraportable laptop or 2-in-1 that has this kind of power needs, something that will be very common in the near future. Sometimes the more power output the charger can make available the better.

Chargers that have two or more outlets, including the many-outlet “charging bars” should be kept for the long haul. It is preferable to have them in the kitchen or the home office especially where you are likely to be charging multiple devices in the same location.

You will be finding that there will be more of the powerful multiple-outlet chargers on the market thanks to power-supply designers, manufacturers and vendors investing in Gallium Nitride technology that allows for compact powerful power-supply devices.

Here, you are factoring in many realities when you use mobile technology. Here, as your portable devices get older, the batteries don’t run for the same long time that they used to when they were new. As well, most of us like to run our portable devices on external power as much as possible to conserve battery runtime.

It is something we used to do with portable audio equipment and some pocket calculators since these devices came around in the 1960s.  We even did things like minimise any battery-draining activities like fast-winding of tapes with our portable tape players unless the equipment was connected to AC power. Or most portable devices that had dial or display lighting had this lighting come on when they were powered from external power but have a button to activate it as needed when on batteries. This was driven by the fact that batteries for these devices that ran for a long time were at a price premium then.

There are also the accessories that support our mobile devices like Bluetooth headsets or powerbanks and these use a USB-based cable for charging their integrated batteries. It is also underscoring that the USB Type-A plug or USB Type-C plug is being seen as the “universal DC power plug” for many devices thus simplifying what we use to power these devices with. For example, some LED-based decorative lighting is appearing that is powered by a USB charger rather than a specially-designed power supply.

As you find that you acquire more powerful USB chargers, you may find that it is high time to send the least-powerful ones away for e-waste recycling. That is unless you are using a device that uses the USB charger purely as a power supply and can work with a low-power USB charger.

You may also find yourself migrating to the newer USB Type-C connection for your devices and then find that it may be a better time to move towards chargers that use at least one of these connection according to the Power Delivery specification.

If you find that your charger uses an IEC-standard “figure-8” or “cloverleaf” AC input socket, this opens up a pathway of flexibility which may give you more reason to keep it. Here, you could use a longer AC cord that has the appropriate connection if you want it further away from the power outlet.

For travel purposes, you may find it simpler to purchase an AC cord with the destination country’s national AC plug to use it in countries using that kind of AC power outlet. Typically you would buy these cables from a local electrical retailer or office-supplies store as an AC cord for a radio or laptop. You then end up with some form of flexibility about where you locate it in your travel accommodation. This situation is more advantageous where you end up frequently visiting countries using that same AC power outlet.

Where should we keep USB chargers?

At least one of these chargers should be kept in each of the main living areas in the house.

If you find that you don’t like the idea of these chargers strewn around the house, it may be a good idea to keep them in a drawer in the appropriate room while they aren’t actually in use. But make sure everyone is aware of the chargers existing in those storage locations when you store them. This is where the ultra-compact chargers really earn their keep because they don’t take up much storage space.

In the lounge areas like the living room or rumpus room, it may be a good idea to keep a powerful USB charger of some form near one or more of the armchairs or couches. This is because most of us would be using a smartphone or, more likely, a tablet there in order to interact with online resources like Wikipedia, search engines or social media when we watch TV for example.

You may find that plugging a charger in to a standard extension cord may work if you are wanting one to serve someone sitting in a chair or sofa that is located away from a wall. Similarly using a powerboard to plug your table or floor lamp and a charger in to may work wonders here. The use of longer AC-current cords may benefit these applications better due to keeping the power conversion process closer to the device using the power and reducing voltage drop where it matters.

The kitchen area may be a good location for a multiple-outlet “charging bar” due to people charging their devices in that area. On the other hand a small two-outlet powerful wall charger may earn its keep here if you are trying to avoid excess clutter.

Dell WD19TB Thunderbolt dock

It is best to focus USB-C and Thunderbolt 3 docks like the Dell WD19TB Thunderbolt 3 dock towards peripherals that are being used with the dock’s host computer

The same goes too for the home office at least. Here, you may be using this as the “go to” place to charge powerbanks and mobile accessories in a location where they can be found. You may think of using that USB-C or Thunderbolt dock that you are using to connect your laptop to the big screen and keyboard for this purpose. But you may find that having a charger, like a “charging bar” may earn its keep here when you are simply charging devices that aren’t necessarily peripherals for your computer so that all USB sockets on that dock serve those peripherals.

You may want to keep a charger or two in the bedrooms if you do charge your smartphone or tablet there. It is also important to make sure the guestroom has one or two of these chargers so that guests who stay overnight have somewhere to charge their devices.

If you do keep accessories on hand for travel, one or more small USB chargers can come in handy here. You could even consider a multi-outlet “charging bar” again for packing when you travel.

At least, making sure you are keeping the powerful capable chargers that work to current standards and keeping them in areas where they are useful can work out as a convenient and effective way to rationalise these devices.

5G Product Page (announcing pending arrival of this Mi-Fi hotspot)

NETGEAR

NIGHTHAWK® M5 MOBILE ROUTER (MR5200) – Product Page

My Comments

Telstra has become the first telco in the world to offer a “Mi-Fi” mobile-broadband router that supports both 5G mobile broadband across all bands including mmWave on the Internet side and Wi-Fi 6 connectivity on the LAN side. This was offered when they initially launched their 5G mobile broadband service and this kind of coverage was important for Australian use where 5G services are likely to be deployed in sparsely-populated regional and rural areas.

AT&T now is offering to the general American public a Mi-Fi device that works on the full 5G waveband for its Internet connection side, and Wi-Fi 6 for its local network side. Here, that covers the lower frequencies of the 5G waveband along with the higher frequencies associated with mmWave coverage.

They previously offered a 5G Mi-Fi device but this was offered to a very limited customer base. Also Verizon offers a similar device with 5G and Wi-Fi 6 but their device only works the mmWave bands rather than the whole of the 5G band.

In addition, the Netgear Nighthawk 5G Mobile Hotspot Pro, also known as the MR5200,  that AT&T offers has an Ethernet LAN connection for use with printers, network-attached storage devices, desktop computers and smart TVs. It has USB-C connectivity, most likely for power and data (5G modem) functionality.

The Netgear Nighthawk 5G Mobile Hotspot Pro is fit for purpose with American emergency service thanks to its ability to work with FirstNet, which is AT&T’s LTE emergency-services communications network,

This device is expected to cost US$510 upfront or US$17 / month over 30 months before service costs. As well, AT&T are offering data service plans for this device with you paying US$60 per month for a 15Gb monthly data allowance or US$85 per month for 35Gb.

Their overage fee is US$10 for every 2Gb over your plan’s limit and, at the moment, they don’t have a “throttled bandwidth” option available for their plans in lieu of that. That will limit AT&T’s 5G mobile-broadband service’s role to a secondary or temporary Internet service. It is symptomatic of an American telecommunications and Internet-service that has become highly concentrated over the last five years with it heading slowly back to the “Ma Bell” days.

AT&T is rolling out 5G mobile-broadband coverage over most of the key cities in the USA that matter with this coverage increasing at the moment.

But AT&T’s Netgear Nighthawk 5G Mobile Hotspot Pro is one of the first devices of this kind offered to a dense Northern-Hemisphere country that ticks all the boxes for the latest wireless mobile-communications technologies. That is to provide 5G mobile broadband across the low frequency bands and high-frequency mmWave bands and supply this data across a Wi-Fi 6 LAN.

It is showing that mobile-telephony carriers are fronting up with Mi-Fi devices that work the 5G mobile broadband and WI-Fi 6 standards, leading to some very capable devices and services.

My Comments

An e-book reader available on the European market is existing as a commercially-available example of a colour e-ink display.

E-ink is a display technology that works in a similar manner to ink on paper and uses existing light. It only consumes power every time the display is refreshed thus making it more power-efficient. It also works well in bright sunlight due to it not being dependent on a light source that can be easily “washed out” by the sun. Its main application has been handheld e-book readers but it has been limited to black-and-white display.

There has been work taking place to have e-ink displays capable of displaying in colour. It has come through in the form of the E-Ink Kaleido colour display which uses the same e-ink technology.

This has manifested in the Pocketbook Color which is an e-reader that has a colour e-ink display.

This EUR€199 device uses a 6” e-ink touch screen capable of displaying 4096 colours, with a resolution of 1072×1448. There is also LED lighting so you can use this device in darker settings. For audio, it can handle AAC, Ogg Vorbis and MP3 files, which can be played through earphones or a Bluetooth-connected audio device.

It has 16Gb of internal storage and can use SDHC memory cards, not sure what size, with a maximum capacity of 32Gb. This handheld device weighs in at 160 grams, something that would be acceptable for that class of device.

For e-book readers, the colour display may be seen as legitimate for visual novels or books that have colour photos or illustrations. Businesses may see it appealing for distributing brochures and catalogues in an electronic format for offline reading. As well, where colour is used to differentiate or highlight text in a book the colour e-reader will come in to its own here. A classic example of this is are the “red-letter” Bibles where the words of Jesus Christ are written in red.

But I also see the idea of a colour e-ink display appealing to other applications like colour digital signage in use cases where battery power is preferred. Examples of these would include outdoors use or freestanding signs. Or it could be about working towards making e-ink as a viable display alternative for laptops, tablets and smartphones where power efficiency is desired.

Microsoft to allow Android apps to run with Windows

Computer - smartphone interlink concept

You can soon run your Android phone’s apps on your Windows computer but they will run in place on the smartphone with your Windows computer being the user interface

Soon launch Android apps on Windows 10 PC via Your Phone app, as Samsung & Microsoft collaborate | Windows Central

Microsoft Your Phone’s Android apps access feature will be available for all Android smartphones eventually | Windows Central

My Comments

Most desktop-operating-system vendors and other third parties are implementing software that interlinks mobile-platform devices, especially smartphones, with your regular desktop or laptop computer.

It is capitalising on the fact that the user interface and software that a regular computer running a desktop operating system has is more capable for making your work presentable, compared to what a smartphone or mobile-platform tablet offers. But your smartphone or mobile-platform tablet can earn its keep for acquiring content for your magnum opus like taking notes, taking quick photos or browsing the Web for material.

This is typically to allow you to gain access to your mobile device’s data or use your mobile device’s native communications ability from your regular computer’s screen and keyboard. Some of these platforms may even allow you to start viewing a Website on one device then continue viewing it on the other device; or even implement a cross-device “clipboard” so you can copy something you saw on your mobile device then paste it in to something you are editing on your regular computer.

But Microsoft have taken this concept further by working on the “Your Phone” interlink software to allow you to run software installed on your Android smartphone from your Windows 10 regular computer. For example, you could effectively manage your Instagram presence using your Android smartphone’s Instagram client but working it with your Windows laptop’s screen and keyboard. Or you could kill time during a long process on your Windows computer by running a “guilty-pleasure” casual game that you normally play on your Android phone but have its user interface happening on the regular computer.

Effectively, this arrangement runs the software on your Android phone but has your Windows-based computer acting as a “terminal” that is providing input and output for that phone.  It is based on Microsoft’s experience with Remote Desktop Protocol a.k.a Terminal Services which allows one Windows computer to effectively control another Windows computer.

Some questions may come about like transferring files between your computer’s Windows file system and your smartphone’s Android file system for uploading to the app, something that will be considered important for Instagram users who upload video content.

When this function is released as part of the next major feature update for Windows 10, it will initially be able to only work with some Samsung devices. But Microsoft will intend to have it fully available across all of the Android-based devices that can run the “Your Phone” Windows interconnector software.

Here, Microsoft is underscoring the idea of allowing “open-platform” mobile-computing and regular-computing devices to interlink with each other no matter the operating system. This is even to the extent of running mobile-platform apps “in place” on the mobile device.

This is with the fight that is going on between Bose, themselves and Bang & Olufsen to achieve the ideal active noise-cancelling headphone experience with their entry being the WH-1000XM3 headset.

This successor, known as the WH-1000XM4, follows on with what the previous model offers like Bluetooth (Hands Free Profile, A2DP, AVRCP) and the optimised active-noise cancelling. But the Bluetooth audio functionality has support for Sony’s codecs that permit playback of high-resolution audio along with audio optimisation for lossy compressed-audio files.

The active-noise-cancelling has been improved to increased useability in real-world scenarios. This includes optimisation of its functionality for situation-specific requirements like hearing transport announcements or background music played over the vehicle’s or aircraft’s audio setup.

There is even the ability to set the Sony WH-1000XM4 cans up to pause your music and admit ambient sound whenever you want to engage in conversation with other people. This can be done fully automatically when you start speaking or semi-automatically when you cap your hand over one of the earcups.

As well, you have touch control for your device so that you swipe in particular directions to switch tracks or raise and lower the volume or tap the headset to start and stop the music or answer and end a call. There is also a button that can be mapped for use with voice assistants or to manage the active-noise-cancelling function.

But Sony has improved on the multipoint functionality that allows the headset to work with two Bluetooth devices concurrently. Here, it switches automatically between the devices based on whatever audio signal is being offered by the device.

But by following the review chatter, Sony has been able to refine the successor to the WH-1000XM3 Bluetooth noise-cancelling headset in order to create the ideal product in this class. Who knows what the competitors will have in store when they revise their products.

Google has been doing work on its own across-the-room data-transfer technology, now known as Nearby Share. It is the Android platform’s answer to Apple’s AirDrop feature that many iOS users are using to “beam” photos to other users.

There have been previous attempts on the Android platform to offer this feature like Bluetooth Object Push Profile and NFC-based technologies like Android Beam.

But this will work in a true-wireless approach with support for Bluetooth, WebRTC and peer-to-peer Wi-Fi technologies. That means it isn’t dependent on a functioning Internet connection for it to run.

Your Android phone or tablet will need to have Android 6.0 or newer and the functionality will be delivered as part of the Google Play Services update. This means that it is updated independently of the operating system codebase, thus answering the problem associated with a lot of Android devices where manufacturers and carriers won’t support the device two years after it is launched.

This feature will have privacy-focused options like anonymous transfer and the ability for users to limit their discovery to only their contacts or only to selected contacts. As well, recipients don’t see the actual material about to be transferred so they don’t get shocked by someone pushing out unwanted material.

A good approach to handling AirDrop, Google Nearby Share and similar across-the-room data-transfer setups in a safe manner is to keep your devices undiscoverable to others. Then, when you have confirmed face-to-face that you are intending to use this function, then you make your device discoverable in order to receive the content.

It is available for ChromeOS but will be arriving as part of other platform primarily through software that Google develops for that platform. But there needs to be further work on having true federation for these across-the-room data-transfer protocols in a manner that doesn’t necessitate the installation of extra application software.

For Android users, Google Nearby Share is a step in the right direction to having across-the-room data transfer happening on that platform.

Lenovo to offer a ThinkPad laptop that directly competes with the Dell XPS 13

Lenovo is tentatively fielding a computer that rivals the Dell XPS 13 ultraportable

Lenovo ThinkPad Nano leak reveals fascinating features — XPS 13 could be in trouble | Laptop Mag

My Comments

The Dell XPS 13 series of Intel-powered clamshell laptops has been seen by the computer press as what an ultraportable laptop should be about such as durability and value-for-money. I even gave some coverage about this unit on HomeNetworking01.info and reviewed some of these laptops including a 2-in-1 variant.

Now Lenovo is answering Dell by offering a similarly-sized ThinkPad laptop, known as the ThinkPad X1 Nano thanks to leaked information that surfaced on the Internet. Like other ThinkPad laptops, this is finished in the black conservative “IBM” look rather than the silver look associated with the Apple MacBook family and the Dell XPS 13.

  1. Here, this will come with at least 16Gb RAM and implement Intel’s newer Tiger Lake (11th generation) Core CPUs which I suspect will be the i5 or i7 types. It will have a 16:10 display with at least 2K resolution along with 5G mobile broadband and the newer Thunderbolt 4 over USB-C sockets offering compatibility with USB 4 and Thunderbolt 3. The expected battery runtime for its 48Wh battery is to be around 17 hours.

The question here is whether Lenovo will still focus the computer towards the “enterprise” segment of the market with a preference to supply all of the security and manageability requirements desired of by Corporate America’s IT teams. Or will there be a desire to make this equally available to personal and small business users who would like to see an alternative to the Dell XPS 13.

Will there also be a desire by Lenovo to rival Dell with the configurations offered at the different price points for both the ultraportables especially when pitching them at regular users? Will there also be a rivalry between those companies to use the latest silicon to design and offer the best value-priced ultraportable through subsequent model generations?

If this is for real, it could open up a strong rivalry when it comes to the market for 13” ultraportable laptop computers. But I hope that the competition is about innovation in this product class with a goal for value for money centred around good-quality equipment rather than a “race to the bottom” where customers are sold substandard products at a cheap price.
