T-Mobile Data Stash: You Can Finally Get Rollover for Your Data Plan | Gizmodo

From the horse’s mouth

T-Mobile USA

Press Release – Data Stash – Don’t Use Don’t Lose (English / Espagnol PDF)

My Comments

Most mobile and fixed broadband services that implement data allowances in their business models have it that you forfeit any of the bandwidth that you don’t use in these plans. This works against an increasingly-common practice of people buying data plans for these services with more data allowance than they really use. This same practice applies to just about all of the mobile providers who provide included talk-time and messaging allowance whether as a combination of talk-time minutes and text / MMS messages or a known value of service use.

But T-Mobile, a spinoff of Deutsche Telekom who is selling mobile telephony and mobile broadband to the US market, is working against this norm. Here, they are marketing this option as “Data Stash” because of the way you can harbour the unused data and work with all of their plans that have an allowance of 3Gb or more. Even existing customers can use this feature which is unlike some carriers who will offer tasty features only to those who start a new account. This is part of their “Uncarrier” program where they offer extra service options and value that other mobile-phone carriers in the USA don’t normally offer.

Here, they offer a “rollover” option for their data plans where if you don’t use all of your data allowance, the unused allowance is carried over to the next month just like what would happen with a bank account. T-Mobile have understood this reality with people buying more than they need and may be needing to satisfy a usage peak, which can be brought on by a change in living conditions, a holiday or simply attending a “big-time” event.

Personally, I would see this as being important with people who use a “Mi-Fi” device like the Samsung LTE Mobile Hotspot Pro or T-Mobile 4G LTE Hotspot Z915 on an occasional basis or use these devices increasingly through certain peaks like summer. But I also see this as a way simply to smooth out the peaks in your mobile-broadband data use and other carriers around the world should have a look at T-Mobile’s offerings to know how to gain the competitive edge.

How Machine Learning Could Stop Drunk Posts On Facebook | Lifehacker

My Comments

The smartphone can end up as something that can cause trouble later on after a party

The party season is on us and some of us can use various electronic communications technologies to do something we would otherwise regret after we have hand a few too many through the party. This could be to use social media to share an embarrassing picture of someone while they were drunk; send a stupid email to someone we know or knew or make that call to “the wrong person”.

Some software developers have worked on various technologies to “put the brakes” on this kind of rash activity such as Google’s effort to implement a problem-solving CAPTCHA when we send an email late at night, the development of iOS apps that mask contacts that we are at risk of contacting when drunk. But Facebook have taken this further by implementing deep-machine-learning in their “slow-down” algorithms.

Here, they use the facial-recognition algorithms that they built for their pioneering image-tagging feature and used this with a mobile device’s camera to identify if the user looks drunk. This is also used with other machine-learning to assess the context of posts and links you intend to post where you are tagging a person in the post so you aren’t at risk of sharing something you wouldn’t otherwise share. Here, it would work with Facebook client software which has access to the Webcam on your computer or the integrated front camera on your mobile device but may not work with web-based Facebook sessions where the browser doesn’t have programmatic access to the Webcam.

This deep-learning could also be used as part of “client-side” software to work as a way of avoiding drunk emailing or other risk-taking activities that you could engage at the computer. As I have seen before, a lot of the advanced machine-learning research doesn’t just belong to a particular company to exploit in its products but could be licensed out to other software developers to refine in to their programs.

Bluetooth 4.2 introduces internet connectivity, ideal for the Internet of Things | Android Authority

New Bluetooth devices will connect directly to the internet | Engadget

From the horse’s mouth

Bluetooth

Standard product page

My Comments

Bluetooth has just “cemented” the latest version of their wireless-personal-network standard at 4.2 .

This will be a major improvement for the “Internet Of Things” or “Internet Of Everything” because each device can have an IPv6 and 6LoWPAN stack to provide a direct link to an IPv6 network. It avoids the need to create a protocol-level bridge between a pure Bluetooth network standard and an IP standard, rather allowing access to the IP network and an Internet “edge” router in the same vein as a Wi-Fi wireless device.

As well, there will be some privacy-based improvements like a requirement for users to interact with their mobile device such as deploying an app in order for the device to work with Bluetooth beacons. There is also the ability to support dynamically-assigned MAC addresses to facilitate this goal. Another improvement is to provide faster data throughput which could speed up things like data synchronisation or provide a “fatter pipe” for more data.

As I have said before, this standard is “baked in stone”, and needs hardware, operating-system and software support for it to take off. Some functions can be integrated in to earlier Bluetooth iterations in order to provide some of the new features to existing devices.

La ville de Berlin lance une application «contre les nazis» | La Figaro (French language | Langue Française)

From the horse’s mouth

Berlin Against Nazis (Berlin Gegen Nazis)

Press Release (German Language / Deutsche Sprache)

My Comments

Another smartphone app has been developed for the community good, this time in Germany. Here, it is a notification app to distribute information about the issue of neo-Nazism to people who live in Berlin.

Smartphones are being seen as activist tools even with custom apps

“Against Nazis” (“Gegen Nazis”), which this fully-free app is called, serves more as a bulletin-board app which shows what is going on around town concerning neo-Nazi activity through the use of push notifications and an interactive map. Through these technologies, this information is distributed effectively real-time. This app allows users to act on the information in order to show solidarity against the neo-Nazi activity that is going on near them or to effectively strengthen the network’s activity. This app has been delivered in German, English and Turkish because of Germany having a distinct presence of Turkish people.

It has been developed by the “Berlin Gegen Nazis” (Berlin Against Nazis) network which is supported by the Berlin local government. This was brought on by a member of this network who was engaged in an anti-Nazi march in Rudolf Hess’s home town when a far-right group effectively took over that march.

The neo-Nazi groups still maintain a presence in Germany although they have a low impact on the national polls and on Berlin’s polls. In relation to Berlin, they have presence in poorer areas of the city like Schöneweide in the former East Berlin. It is also known that people who lived in the former East-Germany areas were soft towards the extreme-right ideology.

This is another way where the mobile phone platforms are being used for the public good especially due to the ease of access that these platforms provide. It also involves creating an information-delivery backbone which is cost-effective for these community organisations.

You can use pictures from your good digital camera with your Android mobile device

Android customization – how to connect a USB flash drive to your Android device  | Android Authority

My Comments

I have a good Canon digital camera and have used it to take some pictures and, at times, place them on Instagram, MMS messaging or other services using my Samsung Android phone. But how do I do this?

Here, this is another virtue of “open-frame” computing which the Android mobile platform wholeheartedly supports. What I did was to purchase a USB “On-The-Go” (OTG) cable and a small SD card reader and used these to get at the pictures on my camera’s SD card. It may be easier to purchase this accessory online or through an independent computer, electronics or mobile-accessories specialist. Some of the camera stores may offer these accessories in order to cater to professional or corporate photographers and videographers who are uploading to Instagram material taken with their DSLRs or camcorders as part of their professional or their employer’s social-media presence.

You can use other memory-card readers with a USB “On-The-Go” cable to suit the memory card that your camera works with such as a CompactFlash card. You may also have to pay attention to the size of these accessories if you want to make sure you can stow them in your gadget bag or camera case.

USB-C – the newer connection type for newer Android phones

Newer Android phones may use a USB Type-C connector rather than the Micro-B connector that is dependent on an OTG cable. Instead, you just need to use a USB cable or adaptor that has a standard USB “Type A” socket on one end and a USB Type-C plug on the other end.

USB On-The-Go cable

Here, I may have to use an Android file manager like ES File Manager to discover the pictures in the camera’s DCIM directory on the SD card. There is even a special file manager pitched at USB OTG applications called OTG Disk Explorer Lite which can be the way if you don’t want to mess with a “full-bore” file manager app.

Newer Android versions and manufacturer / carrier variants may offer an integrated file manager for external USB-connected storage so you don’t have to download a file manager app.

SD card connected to Android smartphone via OTG cable

You may also have to look for a RAW or DNG file app in the Google Play Store which can export as JPEG if you are working with these ultra-high-quality “master” formats for your photos.

Here, I was able to share a good photo of one of Melbourne’s “art trams” via Instagram, simply by taking the picture with my digital camera, then using the USB OTG cable to share the picture on this photo-sharing service. Here, you would have to select the option as of you are picking photos from your image library on your phone, yet look for something like “USBStorageA” or something similar.

Digital camera card shown in ES Explorer Android app

For MMS messaging, I would need to use an app to make “scaled-down” copies of the images to WXGA resolution to send these through that technology. The Android app I use is called “Reduce Photo Size” which makes a local copy of the reduced image so I can send it using MMS.

But some newer SMS / MMS handlers are even integrating the ability to scale down to the right resolution for MMS messaging as part of their function set. This is to cater to the fact that newer Android phones are equipped with high resolution sensors and people don’t want necessarily to go through a process of scaling down pictures they took with their smartphone to send them via MMS. Similarly, when your phone and mobile carrier are part of an RCS (Rich Communications Service) ecosystem, your mobile carrier’s backend equipment will scale the images down to MMS if your correspondent isn’t part of the RCS ecosystem.

I had used this technique when I went on a walk through a neighbourhood that had fond memories for a friend of mine whom I live with and wanted to share some pictures that I took with the Canon camera with those people via MMS which was effectively their “comfort zone”.

SD card reader small enough to stow in your gadget bag or camera case.

I pack these accessories in my camera’s “gadget bag” so I can share photos I have taken with it using Instagram, MMS or similar “mobile-only” services. This can even work with any of the mobile front-ends for the Social Web or cloud-upload services like Facebook, Google+ or Dropbox.

Updated on 2 March 2018 to reflect new trends regarding Android smartphones such as USB-C connectivity, integrated software and RCS messaging.

Deregister iMessage from your number without your iPhone

Apple finally offers an easy solution to its missing text message problem | Engadget

From the horse’s mouth

Apple

Deregister iMessage site

My Comments

If you are moving towards another non-Apple platform for your smartphone or have decided to change your mobile phone number, you may run into issues with Apple’s iMessage “over-the-top” message service which you used as your enhanced messaging service with iOS.

The default setup for iMessage is to route all your regular inbound and outbound SMS and MMS traffic via this service. This can cause problems with you or your contacts not receiving messages if you are moving off the iPhone platform or phantom messages coming through from your old number when you are changing phone numbers.

To deal with this problem, you would typically use the iPhone’s Settings control panel to deactivate iMessage and is something you may have to do before you move off to the other platform or arrange to have your mobile number changed by your carrier.

On the other hand, Apple has provided an answer for those of us who have done the switchover without deactivating iMessage on the iPhone. This can happen when you are in a hurry to switch over or have your mobile service immediately provisioned on your new non-Apple phone.

Here, you visit a page on their Website and key in your mobile phone number to deregister it from iMessage. You will receive a “confirmation number” on your new phone as an SMS, which you then subsequently key in to the Website to set this deregistration in stone. If this doesn’t work, you may have to contact Apple’s technical support to make sure this happens. You may also have to contact Apple’s technical support if you are not receiving SMS or MMS messages on your iPhone after a number change.

This doesn’t affect other iOS or Mac OS X devices that use iMessage because these work on your Apple ID (email address) as being your iMessage address. It primarily detaches your existing mobile number from your Apple ID as an iMessage address.

It could be improved by providing iMessage management through an Apple-hosted Web dashboard that allows you to do things like deregister your phone number or manually add, change or delete phone numbers associated with your iMessage service. This can be of importance with situations like travellers and expats who use SIM cards from providers local to where they are travelling in order to dodge roaming fees or have local-mobile-number presence.

NEC smartphone tech can spot counterfeit goods | PC World

NEC wants you to spot counterfeits using your phone’s camera | Engadget

My Comments

The camera on these smartphones could work towards identifying whether that handbag at the flea market is a knock-off

Previously, I had covered some applications where commodity-priced camera modules have been used for machine vision. These applications, which were mostly based around the cameras that your typical smartphone or tablet are equipped with, were more than just reading and interpreting a barcode of some sort in order to look up data. Rather they were about interpreting a control stick typically soaked in liquid that is used as part of urinalysis or to observe the character of blood vessels on one’s face to read one’s pulse.

But NEC is implementing machine vision using one’s smartphone to determine whether an object like a luxury handbag or a pair of name-brand sneakers is a “knock-off” or not. Here, they use the camera with a macro-lens attachment to identify the “fingerprint” that the metal or plastic material’s grain yields through its manufacture. This typically applies to items made of these materials or where an item is equipped with one or more fasteners, trim items or other fittings made of these materials.

NEC wants to see this technology not just apply to verifying the authenticity of new goods but also be used to allow the manufacturers to check that repair and maintenance of goods is “up to snuff” or follow the distribution and retail chain of these goods.

The manufacturers have to “register” these items in order to create the “reference database” that relates to their goods. As well, users would have to use a macro-equipped device such as a smartphone equipped with a macro-converter attachment or a “clip-on” camera with this kind of lens. They will offer the lenses as a 3D-printed attachment to suit most of the popular handsets and tablets. It could also open up a market for small-form Webcams and similar cameras that come with macro lenses or multi-function lenses.

A missing part of the question would be whether the technology would apply to goods made out of soft materials like cloth or leather. This would take it further with identifying clothes, footwear and “soft-material” luggage or checking whether the material used to upholster furniture reflects what the manufacturer or customer wants for the job.
