Apple and others may have us streaming content on a temporary basis in to our homes after we subscribe to them or another content provider but we will still want to download content to our home networks. This is so we can believe that we really have bought and owned the content rather than perpetually renting it. As well, an increasing number of content providers will take advantage of the digital environment to affordably distribute content under a “to-own” philosophy where we can buy that content in a digital form for cheap.

An example of this would be a few of the US’s well-known magazines, especially National Geographic, offering their back-issues as a collection of PDF files on a CD collection or a USB hard disk. Similarly, we would purchase digital albums of our favourite recordings from various online stores including iTunes. As well, when I went to a travel fair on Sunday 19 February, a country provided an optical-disc-based “slide collection” of images of that country at their stall.

The question that many will ask is how can it be made easier to deposit this content so it is available across the home network. Here, we could copy the files to a public “media folder” on a network-attached storage unit that is on the home network. But we would have to know where that “media folder” exists and how we should present the media to the network. As well, we would need to make it easier for a collection of PDF or other “electronic-book” files to be discovered on a mobile computing device such as a tablet.

A secure network installation routine for small networks

There typically are installation routines in place for provisioning software to computers but these look after putting the software in place on the computer from a user-carried, network-hosted or downloaded package and making the software discoverable in the computer’s operating system. The practice is also similar for delivering software updates and add-ons for network-attached storage devices and other similar devices.

Most media that is purchased online for download is typically downloaded to the user’s regular computer or, in some cases, their mobile device and manually copied to the network-attached storage using the operating system if it is to be shared. It also holds true for digital photos that are downloaded from one’s digital camera or content held on a “carry-through” physical media container like an optical disc or USB memory key. This can be a pain for people who don’t have much computer experience or patience.

One way to make this easier would be to provide a secure simple network installation routine for content collections. This could be based on the routine knowing common variables that represent the content collection and where particular content classes should go. It could manifest in a download handler associated with an online music store that knows the location of the download-music folder on the NAS.

Such routines would need to have a high level of security in order to prevent questionable software from being made available to the network. They will also have to properly support and handle permission systems that are part of most network operating systems.

These routines could allow the copying of “new” media files from the source to particular folders or, in some cases, mount the content collection to the NAS’s file system if it was in something like a USB hard disk such as the National Geographic example. Then it would force the media to be annexed to the index created by the NAS for searching and browsing the media. Of course, there will be the desire to install a skinned microsite which allows one to browse or search a media collection and this would work if the NAS uses a Web server.

Making “electronic-hard-copy” formats discoverable over the network

With DLNA at its current point, it is now feasible to provide images and audio-visual content to nearly every network-enabled audio and video player, allowing users to search or browse for the content they are after. This can be done using the device’s control surface or a control point hosted on another device and the browsing and searching can be performed against many different attributes such as the artist, title, date, user-assigned keyword or genre or a combination thereof.

But this concept hasn’t been extended to the “electronic hard-copy” document that is used for e-publishing. This will become more relevant as we purchase e-books and similar documents and create our own “e-libraries” and store them on NAS drives on our home networks. This will be of importance as large collections of works are made available in electronic hard-copy format for sell-through download or supply on a physical medium like a USB hard disk or optical-disc collection.

Here, PDF, ePub, XPS and other electronic-hard-copy files could support standardised metadata and the DLNA specification could be extended to permit discovery of content held in these electronic hard-copy formats. This would allow people who use e-readers, tablets and smartphones equipped with the right software to discover and download this material to these devices without having to know the file hierarchy of a NAS or use file managers to “pick up” the content. This software could then be integrated in to these devices in a similar manner to how DLNA media player software is becoming de rigeur for the standards-based tablet or smartphone.

Conclusion

The main issue here is that to be comfortable with newer content-delivery methods, we need to he able to do what we used to do in acquiring and annexing the content to household-common content pools so that all members of the household can gain access to the material. This then has to be made easier to d when it comes to file-delivered content especially for people with limited computer skills and what has been made available for photos, music and video content must extend to e-books and similar content. It also must allow the use of standards-based technology that doesn’t tie the user down to a particular vendor.

A trend that I have seen with laptop computers and some all-in-one desktop computers is for them to have their sound output “tuned” by a company involved in the recording or reproduction of music. In a similar vein to how a motor-racing team will work a car destined for street use to improve its performance, these firms, such as Harman (JBL), Bang & Olufsen or Dr. Dre’s Beats Audio,  will work on the sound-reproduction systems to improve the computer’s sound reproduction, whether through its integrated speakers or through headphones attached to the computer.

The main issue that these efforts are trying to conquer is the tinny sound that emanates from the typical laptop speakers. Previously, these computers used just a pair of small speakers installed in their small chassis that didn’t yield good bass or midrange reproduction and they were driven via a low-power stereo amplifier in the computer. The setup was just good enough for audio prompts and, in some cases, speech from people without accents, yet did a horrendous job at reproducing music or sound effects in video or game content.  This is compared to the way even a cheaper portable radio or tape player that is equipped with the traditional 3” cone speaker can reproduce most frequencies “across the board”.  It is made easier due to these sets having a larger cabinet that isn’t crammed out with circuitry and reproducing sound through a larger speaker with a deeper cone. End-users are asking a lot more out of their computers as they use them as personal jukeboxes, movie players and games machines or businesses make heavy use of them as voice and video telephony endpoints.

The challenge is to keep these computers slim yet yield a proper and desirable sound across the audio spectrum. Typically the modifications will focus on the sound-reproduction and amplification circuitry as well as the integrated speakers. For example, there will be digital-sound-processing circuitry that works as a tone control for the computer, with the ability to improve the tone for the integrated speakers.

There will be the implementation of Class-D power amplifier circuitry that is designed by people in the audio industry and the sound will emanate from a multi-way speaker system. An example of this is the ASUS Ultrabooks implementing Bang & Olufsen ICEPower audio amplification. Most systems will use a 2.1 speaker setup with a separate bass driver that may be separately amplified, but some may use a multi-way speaker setup with many speaker units to achieve the sound of larger traditional speakers. As well, there would be some work on planning out the speaker-enclosure area to allow the sound to come out of the system properly.

From what I have noticed when I reviewed many of the laptops, I have come across some setups where the speakers can be muffled easily when you rest your hands on the palmrest, or some computers may sound better when placed on a harder surface. I have also noticed that the screen area isnt necessarily used on most laptops as a place to locate speakers because when you have speakers there, you can improve the stereo separation and sound localisation there.

There are still the many challenges ahead for these sound-tuning projects, where there is an expectation to yield that punchy bass from the built-in speakers. This is usually the kind of stuff that the marketers hype on about when they promote the computers that are equipped with these sound-tuning efforts. Other than that, these efforts have succeeded in putting the life back in to sound reproduction from the larger “new-computing-environment” laptop computers.

HP Blogs – 6 steps for SMBs to become IPv6-ready – The HP Blog Hub

My Comments

There is all the talk of us running out of IPv4 public IP addresses for the Internet, and an increased awareness of IPv6 Internet technology. One major driver for the IPv6 technology is the rolling out of next-generation broadband services; where this feature will be seen as being part of the “next generation” mould.

In the near time, the typical IPv6 network will operate as a “dual-stack” setup where there is an IPv6 network and an IPv4 network operating over the same network space. A device such as an IPv6-ready router will typically bridge the gap between the dual-stack devices and the IPv4-only devices by assisting in the discovery of the devices and transferring data between the two different network stacks.

Outside IT contractors

If you do regularly engage outside contractors for your IT needs such as your POS / property-management technology, it would pay to ask whether the technical staff know about IPv6 and how to deploy it. Most of these contractors may think that small business doesn’t need IPv6 but as the Internet moves to this technology, it pays to be future-proof.

ISPs and Webhosts

It is worth making sure that your business’s ISP and Internet hosted services such as your Webhost are ready for IPv6 or have intentions to roll out a customer-facing IPv6 service.

Most ISPs and Webhosts are likely to have the backend of their services working on IPv6 technology but their customer-facing services like the Web services or Internet service may not be ready. This may be due to the presumption that most customer setups will fail when confronted with IPv6. The exception may be the ISPs that serve a “switched-on” audience that knows their way around the Internet technology; or ISPs and Webhosts that offer customer-facing IPv6 service as a limited-user beta test and they may offer a “dual-stack” setup.

It also pays to check that your domain host supports domain records that are compatible with IPv6 setups. This includes having AAAAA-form DNS records that can resolve your domain name to IPv6 addresses.

Hardware

Computers that run Windows Vista or 7, MacOS X Lion or recent Linux distributions will be ready for IPv6; with Windows XP having support through a downloadable module from Microsoft’s Web site. Relatively-recent computer equipment can be upgraded from prior operating systems to the newer IPv6-compliant operating systems. For the mobile platforms, the IOS (iPhone / iPad / iPod Touch), Android, Symbian and Windows Phone 7 platforms do support IPv6. They will typically operate on a “dual-stack” arrangement by being able to service an IPv4 network and an IPv6 network at the same time through the same network interface,

Similarly, most network printers pitched at the business end of the market that were released over the last few years would have support for IPv6 in a dual-stack setup.

As for routers, managed switches, access points and other network hardware, I would suggest that you check for firmware that supports IPv6 for your existing equipment. Keep an eye on the manufacturer’s Website for newer firmware updates that support IPv6.  If you are purchasing or specifying newer network equipment, make sure that it does support IPv6 or has future support for this in a planned firmware update. Most unmanaged switches, HomePlug-Ethernet bridges and devices that don’t use a Web or SMNP user interface would not need to be compliant with IPv6. This is because these devices work at levels below the IP stacks.

In the case of routers, the device should work as a “dual-stack” unit with support for routing between the two different IP network types. It should also be able to cope with working with a dual-stack Internet service especially as the business Internet services that provide IPv6 will do so in a dual-stack manner.

When I review any network hardware including printers, I will identify those pieces of equipment that are IPv6-ready so as to help you know whether the equipment will be future-proof.

Software

As for software on these computers, any desktop firewall software or other network-utility software that you run would need to support IPv6 operation. This is something that recent versions of this software would cater for, but you should make sure of this when you specify new software. It also holds true for any other network-management programs that need to work on an IP level.

The application software that serves office functionality or line-of-business needs wouldn’t be of concern in relation to IPv6 because the operating system would be handling the network-resource requests for these programs.

Conclusion

The key issue with assuring IPv6 compatibility for your small business network is to make sure that your computer equipment works on dual-stack IPv4/IPv6 software and / or there is a router that works as n IPv4/IPv6 bridge on both sides of the network-Internet “edge”. As well, the IT contractors and services that you engage would need to be knowledgeable about IPv6 and the impending rollout for your business.

Renault debuts R-Link, an in-dash Android system with app market — Engadget

My Comments

The Android operating system isn’t just in your hands anymore with a tablet or smartphone. Renault has made sure it will be in the dashboard of the car, together with an app store to back the concept.

There is a main questions that I have about the concept at the moment. One is whether the system will use an updatable wireless-broadband link or a Wi-Fi network or both for data transfer to and from the network?

But what I see of the idea is the main use of the apps for driver and passenger entertainment, in the form of DLNA-based synchronisation of media with the home network, Internet radio (vTuner and similar Internet-radio directories, Last.FM, Pandora, etc) and similar applications. But there are other app ideas like advanced navigation including “book-ahead” functionality and roadside-telematics integration, and car statistics monitoring.

There could even be the ideas of using this Android platform to integrate the vehicle with home automation. The most obvious scenario that would come to mind would be looking at the dashboard to know whether the garage door that should be closed is infact closed and then touch a button to close it. This could avoid the need to look at the rear-view mirror as you drive out to check on the garage.

At least this effort by Renault with the Android platform could become a platform for developing in-vehicle infotainment and telematics systems and applications.

When you are looking at laser printers to buy for yourself or specify for an organisation, you will come across printers that are known as “LED printers”.

What are these LED printers?

A LED printer and a laser printer are very similar types of printers in so much as how the paper is marked. They use the same dry-process xerographic / photostatic printing method that has been used for years with photocopiers, where there is an electrostatically-charged imaging drum which attracts powdered toner depending on whether it has been subject to light or not. Then this toner is transferred from the drum to electrostatically-charged paper and “ironed on” using hot fuser rollers.

But the main difference is how this imaging drum is illuminated with the digital representation of your document. A laser printer uses a laser beam and swivelling mirrors or pentagonal prisms to scan the document’s image on to the drum. On the other hand, an LED printer uses a fixed row of light-emitting diodes that turn on and off to scan the image to the drum. This LED array would be similar to what is used to illuminate a document when it is being scanned in the typical scanner and each LED light represents a horizontal pixel that is part of the line being printed.

This has benefits for printer design due to the elimination of the complex light path that laser printers use. Here, you don’t need to use mirrors and servo motors to control the laser’s light path, thus you reduce the number of parts that can go wrong. It also leads to the ability to design xerographic page printers that are more compact and lightweight compared to the laser-based units.

Further comments with OKI Data about LED printers

I had engaged in an email interview with Chris Thorley from OKI Data’s Australian head office to learn more about this. Here, I had learnt that they had pioneered this xerographic printing technology in 1981 and are now on their ninth-generation LED print engine.

Most other printer manufacturers use this LED technology on some of their low-end models. The main reason is a reduced part count allowing for reduced material costs; as well as the impact of unforseen technological issues not being considered significant for this market position, compared with using the trusted laser technology on their mid-tier and high-end models.

But OKI Data have implemented this technology across the board with their colour LED printers known to be yielding high colour production quality. It may also be known that some other manufacturers implement the OKI technology in to their production printing devices on an OEM (Other Equipment Manufacturer) basis. This practice is where a manufacturer uses an already-designed subsystem from anther manufacturer (the OEM)  in their own project.

Conclusion

It is worth considering the LED printers for your page-printer needs as long as they have the kind of specifications that you have in mind. This includes machine reliability, image quality, print speed including colour and auto-duplex print speed, functionality and running costs including availability of toner cartridges at differing capacity levels.

There is a new class of ultraportable notebook computer that is being defined through this year and next year by Intel in response to the success of the Apple MacBook Air. You may think that it is no different from ultraportables like the Toshiba Portege R830 that I reviewed on this site.

But these computers, known as “Ultrabooks”, will be intended to put the idea of a “portable-typewriter” size of laptop in the laps of most public-transport and air travellers rather than business executives.

What is the Ultrabook

Like the typical ultraportable of the same ilk as the Toshiba R830, these computers have the 13” screen and the same footprint that makes them useable on that bus or economy-class airline tray table. Yet they will be usable for creating content like typing up those documents and blog posts on the move.

But what makes them an Ultrabook is that they will have an ultra-slim chassis which has to be less than 1.8cm thick when closed and weigh in at 1.4kg or less. The battery runtime has to be longer than five hours which would cater for useable time on a long-distance air trip or a day of hotspot surfing.

The required maximum price for these units is around US$1000 which would put them in to the hands of most users. This price would be applicable to the base model in an “Ultrabook” lineup, with increases in price for extras like increased RAM, faster processors or increased secondary storage.

Functionality requirements

The goal of the functionality requirements it for an Ultrabook not to be an underpowered ultraportable computer just for document creation and basic Internet activity, but to be on a par with a typical 15” laptop that can excel at multimedia or basic gaming.

The main drivers in the design are the use of Intel Core i3,i5 or i7 processors providing the horsepower with the images on the screen painted by Intel HD integrated graphics. These units will have to use solid-state storage technology rather than the orthodox mechanical hard disk for their main secondary-storage system. They will also forego the optical drive as an integrated removable-storage option, so you will have to use a USB DVD drive if you want to view rented DVDs or turn out DVD copies of your photos. Of course there will be an SD card slot so you can download your digital-camera pictures to your Ultrabook for reviewing and editing.

Most such computers wont have the Ethernet or VGA connectivity. Here this will mean that you will need to use Wi-Fi to connect to your home or small-business network 

As well, you will have to connect the Ultrabook to the economy-priced data projector using a DisplayLink USB-VGA adaptor. Of course these units would use either a DisplayPort or HDMI external display connector, usually of the mini form factor.

These connectivity issues will typically be mitigated through the availability of multifunction docking stations that connect to the Ultrabook via a DisplayPort or USB connection. 

The typical Ultrabook will be housed in a sealed case that precludes easy upgrades. But this will typically support the “push-down and replace” practice when users want better functionality or performance. Here, the computer would be disposed of to a user with lesser needs while the user purchases a machine with the specifications that suit their current needs.

Purchasing notes

If you maintain a desktop or larger laptop computer as your main computer, it may be OK to skimp on the secondary-storage capacity if you only intend to use it as a “travel computer”. Then you use the home or small-business network, cloud-services like SkyDrive or USB-attached external storage to keep the data you are working with in step with your main machine.

Other comments

I would like to see AMD and others define a similar name and standard for ultraportables that make this goal so that the computers don’t have to be all Intel-driven. This could then lower the price bar for computers of this class.

Similarly what Windows 8 will offer with touchscreen operation may open up paths towards convertible “Ultrabooks” that are a feasible alternative to a tablet computer.

As well, I would like to see manufacturers avoid making this class of computer become a class of “MacBook Air copycats”. This could be achieved through the use of different colours and finishes or even different materials and textures.

Conclusion

What I like more about the Ultrabook concept is that it puts the idea of a lightweight travel-friendly notebook computer that works well for content creation as a credible alternative to netbooks or tablets.

What are QR Codes

QR code used in a newspaper to link to its mobile site

A QR Codes is a two-dimensional monochrome barcode that is designed to house a long text string. This may represent contact details or Wi-Fi network parameters but is commonly used to provide a link to a Web-hosted resource. These barcodes may be printed on a newspaper, business card or flyer; or even shown on a Website; the latter method being used to show links to software for the Android platform.

Typically, a person who has a mobile phone equipped with a QR-code reader app can then just point the phone’s camera to the barcode and “take a picture” of that barcode. This then leads to the contact details being put in their contact list or the user being taken to the Web site or Web-hosted resource. This function has even been extended to supplying GPS coordinates to a device for navigation (think of geocaching) or, in the case of Android phones, supplying Wi-Fi service parameters to these phones as part of provisioning hotspot service.

A QR code as used on a poster to advertise this site

They are popular in Europe especially with cafes and restaurants but are slowing increasing in popularity in other countries. As well, some commentators have described the QR code as a way of providing a machine-readable hyperlink in the field. It is also worth having a look at various QR-code blogs like this one so you can know what the trend is about.

Infact, when I promote HomeNetworking01.info using posters or business cards, I make sure there is a QR code pointing to the site so that people can use their phones to head to the site.

Why QR codes for your organisation

One major benefit that QR codes have for your print-based campaigns is that you can insert a direct link to your Webpage or a resource on that Webpage. Your audience then can visit that resource without having to memorise a URL or transcribe the URL in to the phone using a small touchscreen keyboard or SMS-style with the phone keypad.

The QR code is better than using Bluetooth transmitters to provide content. This is because the user isn’t likely to be annoyed with “accept this” Bluetooth responses from these transmitters when they come in to range of the transmitters. As well, the user doesn’t have to remember how to enable or disable Bluetooth discovery mode on their device. As well you don’t need to make sure there is a transmitter at the advertisement and make sure there is power to the transmitter, which can make the QR code acceptable even for posters on that noticeboard or shop door.

It is also better than using any of the proposed “near-field communication” technology for linking to Web resources because you don’t need to buy and integrate near-field transmitters in your promotional materials for the technology to work.

Direct Link to deep Web resources

You may want to provide a sound clip, video or PDF file to your mobile users. As well, you may want to link the user to a particular Web page about a product or promotion. But mobile users may find these resources difficult to gain access to on your site because of being required to enter a long URL into that numeric or small alphabetic keypad.

The QR code can provide the direct link to your campaign page, PDF file or audiovisual resource in a manner that is ready to download “there and then”. If the resource is a YouTube video, you can provide the link to the video clip as it appears on YouTube and the site or local YouTube client can open when the QR code is scanned.

Appropriate for the Social Web

Here, the QR code can augment your Social Web campaign because most active Social-Web users tend to work their Facebook or Twitter presence more from their smartphones. This is especially as I have noticed a lot of small businesses promote their Facebook presence online through posters and flyers that have the “Like us on Facebook” slogan.

What a simplified way of doing this by pointing the latest ultra-cool iPhone to the QR code on the poster attached to the trendy cafe’s espresso machine or refrigerated display cabinet in order to “like” that cafe on Facebook. It certainly makes it certain that you are seen with that iPhone.

Reading QR Codes

Some mobile-phone carriers and manufacturers will supply a QR-code reader with their Internet-enabled camera phones. But iPhone, Android, Blackberry and Windows Phone 7 users can come across many free QR-code readers at their platform’s app store. One example that comes to mind is the free i-Nigma which started becoming available for the iOS platform but lately became available for the Android and Blackberry platform. There are others like Barcode Scanner for the Android platform, BeeTag for the Blackberry platform and ScanLife for most of the platforms.

A main difference that may sort the “sheep from the goats” as far as QR-code reader programs go is whether they can read a light-coloured QR code that is printed on a dark surface. Similarly, there may be differences in how well a difficult-to-read code like a double-sided sign that is backlit can be understood.

At the moment, most QR-code readers are pitched at handheld mobile phones for immediate viewing of the resources on these devices. But it could be feasible to provide “capture-store-sync” transfer of Web URLs or downloaded resources to desktop operating systems or tablet computers as a feature of a QR-code reader. This could then allow a person to view the Web site on their laptop computer using their favourite Web browser at a later time.  It would also be of importance with QR codes being used for presenting Wi-Fi network parameters to Android phones, where the same parameters can be passed up to a laptop and integrated in to the Wi-Fi networks list for that computer.

Preparing QR codes

There are many QR-code generator sites and programs, most of which are free to use. Typically these sites may allow you to provide a URL to a resource as the input text or prepare contact details. A good resource to start from is this blog’s list of the top 10 free QR-code generating sites. As well, i-Nigma also offer a free QR-code generating page as well as their QR-code reader. Yet another resource is the QReateBUZZ Webpage which I have used for the QR codes for promoting this site.

These codes can be yielded as a small, medium or large size. Here, you could use a small size code for business cards and flyers here you don’t have much room or just want a discreet code on the corner of the poster. You could then use the larger sizes if you want people to notice that there is a QR code in the signage’s artwork or need to be far from the artwork to scan it.

Most sites will yield high-resolution PNG or JPEG bitmaps but some may yield EPS Postscript files or PDFs that are vector-images of the QR codes. You typically will then copy-and-paste or import the mage in to your artwork. As well, a lot of the sites will generate a JPEG image that you copy from the site using Ctrl-C / Command-C and paste to your artwork using Ctrl-V / Command-V.

Of course, there are some desktop QR-code generator programs which will run on a regular computer but most of these are Windows-only and a lot of them are offered at “large-business” prices.

It is still good practice to work with dark-graphics-against-light codes because most QR-code readers cannot work effectively with light-graphics-against-dark at the moment. If you are setting a QR code on a dark background, you could use the dark graphic on a light background and have a distinct light-background margin around that barcode.

Conclusion

Once you explore the creation and use of QR codes as part of your online and offline marketing strategy especially where you have online resources
