Press Release

My Comments

Over the last year, there has been a slow trickle of external graphics modules that “soup up” the graphics capabilities of computers like laptops, all-in-ones and highly-compact desktops by using outboard graphics processors. Typically these devices connect to the host computer using a Thunderbolt 3 connection which provides a bandwidth equivalent to the PCI Express expansion-card standard used for desktop computers.

At the moment, this approach for improving a computer system’s graphics abilities has been focused towards gaming-grade graphics cards and chipsets, which has left people who want workstation-grade graphics performance in the lurch.

But NVIDIA has answered this problem by providing a driver update for their TITAN X and Quadro workstation graphics cards. This allows Windows to work with these cards even if they are installed in a “card-cage” external graphics module rather than on the host computer’s motherboard.

Not just that, NVIDIA are to start allowing external-graphics-module manufacturers to tender their products for certification so that they are proven by NVIDIA to allow these cards to work reliably to optimum performance. This may be different to the context of a certified workstation where all the components in that particular computer are certified by Autodesk and similar software vendors to work reliably and perform at their best with their CAD or similar software.

What is being pitched in this context is a “thin-and-light” laptop of the Dell XPS 13 kind (including the 2-in-1 variant);  an “all-in-one” desktop computer like the HP Envy 34 Curved All-In-One or an ultra-compact “next unit of computing” unit like the Intel Skull Canyon being able to do workstation-class tasks with the kind of graphics card that best suits this computing requirement.

The question that some workstation users will then raise is whether the computer’s main processor and RAM are up to these tasks even though a workstation-grade graphics card is added on; and then consider this approach unsatisfactory even though the host computer has a lot of RAM and / or runs with a Core i7 CPU. But something like a gaming laptop that uses a gaming-calibre graphics chipset may benefit from the Quadro in an external graphics “card cage” module when this system is destined to do a lot of video editing, CAD or animation work.

Personally, I see the concept of the Quadro workstation graphics chipset in an external graphics module as a way to allow hobbyists and small-time professionals to slowly put their foot in the door of high-performance workstation computing.

Product Review–Dell XPS 13 2-in-1 convertible Ultrabook

Introduction

Dell has established the XPS 13 as a value-priced Ultrabook that ticks the boxes when it comes to the kind of functionality that it offers for its product class. There was some doubt that they would offer a “2-in-1” ultraportable computer under this banner alongside the traditional “clamshell” model, due to there not being an essential need for that class of computer.

Now they have offered a 2-in-1 convertible variant of the XPS 13 and it is what I am reviewing. There are two different configurations being offered for this model, one with the Intel Core i5 CPU, 8Gb RAM and 256Gb solid-state storage alongside the premium variant which comes with an Intel Core i7 CPU, 16Gb RAM and 512Gb solid-state storage.

Aesthetics and Build Quality

Tablet mode

The Dell XPS 13 2-in-1 had the same build quality as the XPS 13 clamshell where it came across as being very durable. The outside is finished in aluminium while the keyboard surround maintains that rubberised finish that provides that tactile non-slippery feel. The only disadvantage I see with this is a combination of oily hands and fine dusty materials may have it look dirty.

This convertible smoothly swivels all the way from closed to a tablet position and even closes up neatly and tightly. This again makes for something that has the smooth feel to it.

Tent mode

I paid attention to how this computer kept its cool, with respect to system performance, battery runtime and user comfort. Here, I haven’t noticed any overheating going on even after I viewed video content on this system. This is thanks to the metal housing and the way the system is architected to work in the context of an ultra-thin design.

User Interface

The illuminated keyboard has that distinct feedback that allows for accurate typing especially if you are a touch-typist. It lights up in an “on-demand” manner that avoids excessive battery drain but can be turned off. The way I have seen the keyboard light up means that the keys are more discoverable especially for those of us who are one-finger or two-finger typists.

The multi-touch trackpad works as expected and doesn’t act in a hair-trigger manner, so you don’t have to worry about disabling it if you are working on your lap. The touchscreen works as expected for a tablet screen but at times can be a bit unresponsive especially if you have your hands on the edge.

The Dell XPS 13 2-in-1 comes with a one-touch smartphone-style fingerprint reader just under the keyboard where you just put your finger in the one place for it to be recognised. This works in conjunction with the Windows 10 Hello functionality that allows for fingerprint recognition and Dell also supplied the Keeper password vault for those of us who want to keep our online service passwords on a secure digital keychain.

Here, it is the second consumer-focused computer that I have come across for review to be equipped with such a device, something typically associated with business-grade computers. What I had found from my experience was that it was reliable to scan even if you had something like the oil from deep-fried food on your fingers. But you have to scan your finger lengthways as well as pointing vertically during the Windows Hello setup procedure so it works when you are using the XPS 13 2-in-1 Ultrabook as a tablet.

Audio / Video

The Dell XPS 13 2-in-1 implements the MaxxAudio sound-tuning but I have tried it with playing music using the Spotify online music service. Here, the sound from the internal speakers is very typical of what is offered for laptops, especially the “thin-and-light” units thanks to the small chassis. This means that you don’t get the full sound reproduction when you use these speakers and it may be good enough for notification sounds or dialogue, but I would recommend using external speakers, headphones or a sound system if you want to enjoy playing music through this laptop.

The video playback behaviour for this computer has come through very smoothly especially with on-demand content and can show that you could use it for any class of video content. It would also work well for gaming environments that aren’t too demanding.

Connectivity, Storage And Expansion

Left-hand-side connections – Thunderbolt 3 over USB-C port with PowerShare and USB Power Delivery, audio input-output jack

The peripheral-connectivity options for the Dell XPS 13 2-in-1 are a pair of USB-C connectors. One of these is a Thunderbolt 3 connector that comes in handy with equipment like external graphics modules while the other is equipped with DisplayPort alt connectivity for use when you want to connect an external screen as long as  you use the appropriate adaptor or expansion module dock. Both of these ports implement the USB Power Delivery specification and also implement the PowerShare “sleep and charge” option, only enabled through the BIOS user interface rather than a Windows program.

Dell XPS 13 2-in-1 Ultrabook - USB-C power

USB-C as the power connection

The Dell XPS 13 2-in-1 has become the first computer model that I have had access to for review which implements the USB-C connections exclusively as a peripheral connection and power-input connection. It is a sign of things to come with laptops that are designed to be thin and light where this kind of connection will be the only peripheral connection type. But I am pleased that there are the two connections compared to just one of them, thus still allowing you to connect more devices at once.

Right-hand-side connections – USB-C port with DisplayPort alt video mode, USB Power Delivery and PowerShare; MicroSD card reader

There is also an audio jack as the other device connectivity option, compared to the XPS 13 which implements standard USB connections for other peripherals. Let’s not forget that the XPS 13 2-in-1 comes with a short adaptor cable that allows you to connect devices with the traditional USB Type-A connector to one of the USB-C sockets. If you are wanting more connectivity, I would consider using the Dell DA200 USB-C connector module if it is just external displays, USB peripherals and an Ethernet networks segment you want to connect or the Minix Neo C USB Multiport Adaptor if it’s your digital camera’s SD card you want to download while being able to connect external displays, Ethernet networks and other peripherals.

The secondary storage options available are adequate for most portable-computing needs. This is through the entry-level variant coming with a 256Gb SSD and the premium variant coming with the 512Gb SSD. Personally, I would like to see Dell offer a step-up variant or mid-tier option with the 512 Gb SSD as the only incremental feature over the entry-level model to court those of us who aren’t chasing the performance expectations but want something that can make it appeal as a sole-use computer.

Thanks to the slimline design goal, the Dell XPS 13 2-in-1 convertible laptop has a microSD card slot as its integrated removable-media option. This will be a limitation for those of us who use digital cameras or camcorders and want to download images to the computer by removing the SD-card “film” from the camera and inserting it in the computer. In this case, you would have to use an SD card reader that plugs in to the computer’s USB-C port with or without an adaptor.

The Wi-Fi network adaptor still works effectively even if it is on the fringe of a Wi-Fi network segment and still provides the necessary throughput.

Battery Life

The non-removable battery in the Dell XPS 13 2-in-1 convertible Ultrabook is able to satisfy general-purpose computing tasks for a day without the need for you to carry the charger with you. I even ran a TV show from SBS On Demand for an hour and found that the battery had 68% capacity left in it after that.

These results may be typical for a relatively-new machine and the battery may not last as long for a unit that has been in service for many years.

Other Usage Notes

The people in the different communities that I associate with whom I have shown this computer to are impressed with the fact that this computer answers the thin-and-light market call while also being an elegant 2-in-1 convertible. At the moment the only thing that will put them off the computer would be the price.

Limitations And Points Of Improvement

As far as the USB-C connections go, an improvement I would like to see would be to provide the same advanced connection types i.e. Thunderbolt 3 and DisplayPort alt on both ports. This may involve having the computer effectively have two Thunderbolt 3 host interfaces and two DisplayPort connections off its Intel HD integrated graphics circuitry, but could allow for simplified error-proof connectivity of display devices and Thunderbolt 3 peripherals.

In relation to the Thunderbolt 3 connection, the Dell XPS 13 2-in-1 could implement a high-power performance-focused stance while it is connected to an external graphics module that supplies the right amount of power. This would then make it able to handle advanced graphics tasks like gaming at home, but this may be limited by issues regarding heat management for a thin-and-light chassis.

A feature that would improve the Dell XPS 13 2-in-1’s useability would be to have dedicated volume buttons on the edge of the screen or as touch buttons on the bottom of the screen to allow the user to instantly regulate sound volume when playing multimedia. This would be more of importance when the computer is operating in a tablet, presentation viewer or tent mode.

Similarly, providing a standard SD card reader in a 2-in-1 Ultrabook like this may be a challenge but could be looked at especially for those of us who use these computers to download pictures or footage from our good digital cameras or camcorders

Conclusion

I would see the Dell XPS 13 2-in-1 Ultrabook as a viable option for someone who is after a “Yoga-style” convertible notebook but want something that conveys a thin, light and elegant image. The configurations that are available at least put its RAM and storage capacities above average for its peers offered by its competitors and definitely underscore value for money for its product class.

Europeans could compete with Silicon Valley when offering online services

Map of Europe By User:mjchael by using preliminary work of maix¿? [CC-BY-SA-2.5 (http://creativecommons.org/licenses/by-sa/2.5)], via Wikimedia CommonsVery often I have read articles from European sources about the Silicon Valley companies not respecting European values like privacy. This ends up with the European Commission taking legal action against the powerful Silicon Valley tech kings like Facebook or Google, ending up with placing requirements or levying fines on these companies.

But what can Europe also do to resolve these issues?

They could encourage European-based companies to work on Internet services like Web-search, social networking, file storage and the like that compete with what Silicon Valley offers. But what they offer can be about services that respect European personal and business values like democracy, privacy and transparency.

There has been some success in this field in the aerospace industry with Airbus rising up to challenge Boeing. This was more evident with Airbus releasing the A380 high-capacity double-decker long-haul jet and Boeing offering the 787 Dreamliner jet that was focused on saving energy. Let’s not forget the rise of Arianespace in France who established a competing space program to what NASA offered.

But why are the Europeans concerned about Silicon Valley’s behaviour? Part of it is to do with Continental Europe’s darkest time in modern history where there was the rise of the Hitler, Mussolini and Stalin dictatorships, underscored by Hitler’s Germany taking over significant areas in France and Eastern Europe before the Second World War. This was followed up with the Cold War where most of Eastern Europe was effectively a group of communist dictatorships loyal to the Soviet Union. In both these situations, the affected countries were run as police states where their national security services were conducting mass surveillance at the behest of the country’s dictator.

There are a few of these businesses putting themselves on the map. Of course we known that Spotify, the main worldwide online jukebox, is based in Sweden. But Sweden, the land of ABBA, Volvo, IKEA, Electrolux and  Assa Abloy, also has CloudMe, a cloud-based file-storage service on their soil. It is also alongside SoundCloud, the go-to audio-content server for Internet-based talent, which is based in Germany. The French also put their foot in the IoT space with a smart lock retrofit kit that has Web management with its server based in France.

A few search engines are setting up shop in Europe with Unbubble.eu (German) and StartPage (Dutch) metasearch engines in operation and Qwant and Findx search engines that create their own indexes. But the gaps that I have noticed here is the existence of a social network or display ad platform that are based in Europe and support the European personal and business values.

There are also the issues associated with competing heavily against the Silicon Valley giants, such as establishing presence in the European or global market and defining your brand. Here, they would have to identify those people and businesses in Europe and the world who place emphasis on the distinct European values and know how to effectively compete against the established brands.

The European Commission could help companies competing with the Silicon Valley IT establishment by providing information and other aid along with providing a list of European-based companies who can compete with this establishment. They could also underpin research and development efforts for these companies who want to innovate in a competitive field. It can also include the ability for multiple companies in the IT, consumer-electronics and allied fields to work towards establishing services that can have a stronger market presence and compete effectively with Silicon Valley.

My Comments

Recently the computer press has been awash with articles that Microsoft was killing the Paint app that always came with Windows since 1.0 . But they are keeping it available for Windows users to continue working with by allowing them to download it for free from the Windows Store.

The Paint app was simply a basic bitmap-driven graphics editor that allowed users to get used to using a mouse for creating computer graphics. It was based on ZSoft’s PC Paintbrush which was the PC’s answer to the various baseline graphics editors that came with every mouse-driven graphical user interface since 1984 when that kind of computing came on board with the Apple Macintosh.

This app ended up being the answer for any basic computer-graphics work at home or in the office, whether it be children creating computer drawings through to designers creating rough prototypical images of what they are designing in the office. I have infact used Paint as part of creating screenshots for this Website by editing the various screenshots whether to redact private information or to call out particular menu options that I am talking about in the accompanying article. This was thanks to an easier learning curve that this software implemented from Day 1.

A common fear that I would have expressed in relation to the press coverage about Microsoft abandoning or paying less attention to Paint and other bundled or cost-effective graphics tools (remember PhotoDraw?) is that they could end up stripping down their application-software portfolio of titles seen to be less valuable. Then they would just focus their efforts on the popular premium business software like the “Office” essentials such as Word, Excel and PowerPoint.

At least those of you who buy a computer with Windows 10 Fall (Autumn) Creators Update in situ don’t have to miss that basic Paint app because it’s not delivered “out of the box”. Rather they can raid the Windows Store and find this app.

But could this be the path for evergreen software that was always distributed for free as a standalone package or with operating systems like graphics or sound editors by the major operating-system vendors?

My Comments

I have given regular mention of Google Home as a competitor in the smart home assistant space alongside Amazon Echo. At the time I wrote the previous articles, none of these services were available in Australia.

But since this week, Google Home has become the first of the smart home assistant platforms to be released in to Australia. They are offering these devices for AUD$199 at least through JB Hi-Fi, Harvey Norman and Officeworks, and is being linked to most of the ABC live and on-demand audio services along with Sky News and Fox Sports for local news services.

Google have even gone out of their way to promote this device on the TV by using an Australian-localised 30-second version of their Super Bowl TV ad including a question about the noise a kookaburra makes.

But I would suspect that Amazon won’t take this lying down and there will be pressure to make sure that their Echo devices and Alexa platform are on the scene as soon as possible. This would also apply to Microsoft and Apple when they get their home assistant platforms off the ground.

Microsoft cuts down the out-of-action time users face during the Windows upgrade cycle

Article

Windows will be improving the time it takes to upgrade the operating system

Microsoft is tweaking the Windows 10 upgrade process to reduce downtime | Windows Central

My Comments

A common situation that we face when we update or upgrade the operating system on our computers including our mobile devices is that the device is out of action for some time while the update take place.

Here, the holy grail for operating-system maintenance is that the updates take action once they are delivered rather than needing us to restart the device at all. In the context of business, this means that workers and business owners are able to stay productive without waiting for an update cycle to complete.

Most of these processes involve downloading the necessary files that contain the newest software code then performing fail-safe procedures. This is before the device is rebooted as a measure to make sure the extant software files are unencumbered before they are replaced with the freshly-downloaded files. Then the update procedure makes sure that everything is in place before allowing the user to interact with the system.

Microsoft identified some of the problems associated with the upgrade cycle associated with their Windows operating system and found that a lot of the preparatory work could take place before the system has to be rebooted.

Previously, the user-created configuration and other data had to be backed up and the operating-system files were prepared for installation after the computer was rebooted to instigated the software-update cycle for Windows. Now, from the Windows 10 Fall (Autumn) Creators Update onwards, these procedures will take place before the system has to be restarted. This is because most of these procedures are simply about copying files between locations on the System Disk.

The data-migration action will take place after the system is restarted and the user data will be restored once all the downloaded files are in place. Then the system will be restarted in order to make sure all the functionality is effective and, like with major functionality upgrades, the user may have to interact with the system further to enable this functionality.

The idea behind this move is to have all the preparatory work done while you are able to work with your computer so that it is out of action for a minimal amount of time.

The question here is whether this improved software-update process will take place for maintenance-level updates like the regular software patches and security updates that are delivered to keep Windows secure.

There is still the issue faced with all of the operating system update procedures, especially with significant updates or where mobile devices are concerned. This is where the update requires the device to be rebooted twice and spends some time out of action during that cycle. It also encompasses the requirement for regular computers to boot at least once while patches and security updates are being deployed.

But Microsoft’s step with improving the software-maintenance cycle for the Windows 10 operating system is getting us one step closer towards cutting down on the downtime associated with this process.

What is Bluetooth Mesh networking all about

From the horse’s mouth

Bluetooth SIG

Blog Post

My Comments

Bluetooth SIG have publicly launched the Bluetooth Mesh specification which adds on to the Bluetooth Low Energy specification to create a multi-device wireless mesh network, It is in addition to the “one-to-one” Bluetooth topology typically used for linking your smartphone to that Bluetooth speaker or the “one-to-many” broadcast-driven Bluetooth topology used for Bluetooth wayfinding beacons.

Such networks place importance on a “many-to-many” network topology where data can be shared amongst multiple network member devices while a member device can receive data from multiple other member devices. The signal paths effectively represent the lines of wire that make up a piece of wire meshing like “chicken wire” while each corner in that mesh represents the member devices in that network.

The “Internet Of Things” is being seen as a key application driver and I see it as a competing wireless-link technology to Zigbee and Z-Wave which are used for this similar application. Security will be designed in to this network technology to protect data from being listened to or modified by unauthorised parties, thanks to improved link-level encryption technology.

It will still have the same use cases as other technologies pitched at the “Internet-of-Things” space such as the smart home, building automation, health monitoring and industrial automation. But it takes advantage of the fact that Bluetooth technology is commonly integrated into the design of highly-portable host computing devices like smartphones, tablets and laptops, something that has been taken advantage of with some Bluetooth-based “smart-home” devices like the Kwikset Kevo smart deadbolt lock. Here, the host device can interact directly with one or more of these sensor or controller devices no matter how far it is from the host.

What will this mean for existing Bluetooth LE setups

The new Bluetooth Mesh network technology will be based on Bluetooth 4.0 LE Smart technology and extant Bluetooth chipsets that support in-field firmware updates can benefit from this functionality. Issues that may be faced include the memory capacity and computing power that the chipset may have, which may affect some designs, and will raise its head with chipsets deployed in a lot of sensor or controller devices.

Devices like smartphones or computers will need to be equipped with mesh-specific add-on software as part of their Bluetooth application-programming interface. Initially this may be delivered in the form of extra software tied to Bluetooth chipsets. But this functionality would be rolled in to operating systems through a subsequent functionality update.

The act of provisioning new Bluetooth Mesh devices will be driven by a host device running a configuration app or, more likely, an extra setup option in the host’s operating system. This is more about enrolling new devices to a Bluetooth Mesh network as well as removing devices surplus to need from that network, which also includes obliterating security keys associated with that network frim the surplus device.

The Bluetooth Mesh technology will be rolled out over the subsequent few years as newer capable chipsets come on board with this functionality and the firmware is made available for suitable extant chipsets. As well it may require each of the major operating systems to acquire a major functionality update to take place before more host devices can work in the Bluetooth Mesh.

At least the Bluetooth Mesh technology will be on a similar position to Zigbee and Z-Wave for wireless infrastructure that answers the needs of the Internet Of Things.

Why I refer to desktop and laptop computers as “regular” computers

Dell Inspiron 15 Gaming laptop

Why I refer to computers like this as “regular” computers

Through this Website, I refer to the desktop and laptop computers that run Windows 10 PC, macOS, desktop Linux or Chrome OS as regular computers and refer to these operating systems as regular-computer operating systems. This is in a manner to distinguish them from the smartphones or tablets that run iOS, Android or similar mobile-platform operating systems, or devices like Smart TVs, games consoles or vehicle infotainment systems that run a dedicated operating system.

It is based on the fact that these desktop and laptop computers have their design roots in the original personal computers that were built and sold from the late 1970s. Here, the goals were to concentrate all of your computing power to a box that existed at your workspace while you were using it with the system able to do whatever task you wanted it to do once you loaded the appropriate program.

Another factor that is also underscored is the way that the “regular” computer can be optimised to suit one’s computing needs more easily through the use of an operating system designed to be highly configurable from the outset. This includes the ability to choose computers with the right amount of performance for what you want to use them for, the ability to connect devices to them so they can answer your needs better or even modify them to suit newer needs.

It was compared to the previous idea of computing which was centred around large mainframes kept in special computer rooms and users interacting with them using “green-screen” VDU terminals. As well, they have been seen since that period as the example of what desktop or personal computing was about.

It is compared to the mobile-platform devices that had their design roots in the handheld mobile phones and PDAs that came through in the 1990s. Here, it was about a battery-operated device you could hold in your hand and carry personal information with you or use as a communications device.

It is also compared to the likes of games consoles, Smart TVs, set-top boxes and vehicle infotainment systems that are designed around a particular goal. These implement a particular operating system or variant of a desktop operating system highly shoehorned for high-reliability “always-alive” operation in their chosen primary task.

The reason I use the term “regular computer” rather than “personal computer” for this class of traditional computer design is because there may be an argument that the mobile-platform devices like today’s smartphones are more of a personal computer than the traditional devices. There is also the fact that businesses have purchased these computers and implemented them as the workspace-based all-in-one solution for your office tasks since the late 1980s.

Here, it is to distinguish these desktop and laptop computers, including the tablets and 2-in-1s, that are using the traditional computing architecture and running the likes of Windows, macOS or desktop Linux from the other classes of personal-computing devices that have become more popular.

How to look after your video projector properly

Praise and worship at church

Making sure your video projector is looked after properly will mean that it will serve your organisation for many years to come

You have bought that new video or data projector for your small business or community organisation and are excited to have it as the “go-to” device to show large images on that wall but you need to make sure it lasts a long time. This is easily achievable if you look after it properly.

This also applies to those of you who purchase a video projector for that home-theatre setup that you invest time and money in to.

With projectors that aren’t based on solid-state “lamp-free” LED/laser-based lighting technology, the lamp that shows the image on the wall or screen also generates a significant amount of heat while it is on. Preventing a build-up of heat in the projector avoids damage to the machine’s lamp and other electronics installed in the unit.

I have written out this information especially for situations where your projector is likely to be used by many different people such as a small business with a high staff turnover rate or a community organisation that has many different volunteers coming through. It is also available as a download-to-print PDF reference sheet that you can keep with your projector’s documentation or operating procedures for your AV setup.

Make sure you set up the projector on a sturdy surface before you turn it on.

This is especially important for transportable setups where you set up the projector before each showing and pack it away when you are finished with it. The table or desk that the projector is to sit on must be stable and in good order. As well, if you use something to raise the front and/or back of the projector to get the picture right, make sure that the setup that you use is sturdy.

Economy data projector with VGA input sockets

The projector has to be on a sturdy surface

In the case of an integrated installation, you must use a good-quality mount kit and make sure that the projector is properly anchored to the mounting surface which should be installed properly.

Make sure you properly shut the projector down at the end of the session

Projector remote control - power button called outUse the standby switch on the projector’s control panel or its remote control to shut down the unit.

At this point, the projector’s fan will run for some time to remove the built up heat from inside the unit while the lamp and electronics is switched off. This will be indicated with a different light that flashes or glows during this process.

You are ready to disconnect the projector from the AC power when its fan stops and only the “standby” light glows or no lights glow on the projector that indicate operation.

Avoid the temptation to turn the projector on and off too frequently

If you need to blank the screen during your show, such as while you are preparing other material to be shown, use the Mute or Blank button on the projector’s control panel or remote control or use the similar “blank-display” function on your display computer’s software or source device.

If your projector uses filters that are easily replaceable, clean them on a regular basis.

Also cleaning the projector’s ventilation grilles on a regular basis can also help towards maintaining proper cooling for that machine especially if it is used or stored in a dusty area. This can be done with your vacuum cleaner’s nozzle.

Be aware of how your projector’s fan sounds while you are using the unit or shutting it down.

The fan should be making no more than a quiet whirring or whooshing sound. If you hear excessive noise like a grinding, buzzing or squealing sound from the projector’s fan, it is a telltale sign that the fan’s bearings are on the way out and it could cease to do its job as well as distracting your audience. This leads to unreliable operation and excessive heat buildup.

When you hear the excessive noise from the projector’s fan, have the projector taken to a repair workshop to have the fan replaced.

Conclusion

Once you know how to look after your projector by avoiding unnecessary heat buildup, you can be sure it will serve you reliably for a long time.

An issue that may face a games developer who wants to work the independent path is how they can put the game on the map as far as the public is concerned. For some developers, the importance is about avoiding heading to the “Hollywood of electronic games” where computer games become very similar in quality to the Hollywood blockbuster movies or popular American network and cable TV shows which ends up with the same-old content amid questionable ethics.

Google Play Store – a step towards the indie game market

One way would be to put the games on one or more platform-specific app stores like the iTunes App Store, Google Play or Microsoft Store. On the other hand, if the game is to be targeted at regular computers, it may be about offering the games to indie-focused software markets like GOG Galaxy or the upcoming Jump subscription-driven market.

The second option appeals to those who want to keep it purely without mainstream influence, as if it is like offering indie-music records through the inner-urban record stores and having it played on community radio stations or by venues visited by the target audience like the cool cafes. It may also include making the games downloadable through the developer’s own Website. But it may only appeal for Windows, Linux or Mac regular-computing platforms. This approach may simply appeal to those who

But Google has taken a process similar to a mainstream full-line music outlet running and promoting an “indie” genre. Here, they are running the “Indie Games Festival” in San Francisco to draw out indie games developers and have them offer the Android platform the best software they can provide. What I see of this is it is a way to stimulate the indie games market especially courting those developers that are writing for mobile platforms.

I even see the Microsoft Store in a better position to court the indie games developer who doesn’t mind going down the second path by encouraging them to develop games for the Windows platform and the XBox One console in a “write-once” approach. Here, they could take a similar approach to Google by running a dedicated festival for indie games developers who want to approach regular-computer and games-console platforms.

At the moment, when it comes to the games for the regular computer, being able to use a dedicated indie-game market or using an established games market like Microsoft Store, iTunes Mac App Store or Steam are the viable games options. But when it comes to targeting other devices like mobile devices, games consoles or set-top devices, the only way would be to use the platform-specific app stores and unless the platform encourages quality independent software development, these will be very limiting for the indie games developer.

There still needs to be interest in and support for the indie games market from many app stores and games markets so that electronic gaming is an environment for high-quality electronic games that appeal to all people.
