Author’s one-stop resource troubleshoots computer problems

May 30th, 2010

Personal computers can become very expensive if every time the computer freezes up, crashes, or fails to turn on, a technician must be called to restore it to operations. That’s why veteran Xulon Press author Lonnie L. Williams penned Williams Sundial Properties:

A Computer Handbook! ($10.99, paperback, 978-1-60957-102-3) This insightful new release teaches readers the basic operation of their personal computer and offers helpful tips for troubleshooting any problems that may arise, including dealing with the technical support team that represents the product.

“The main principle that I would like for readers to take away from this book is the fact that if you learn the basic operations of your personal computer, you can save money,” the author says.

“Personal computers can become expensive if every time the computer freezes up, crashes, or fails to come on, you must call an electronic technician from a consulting firm to restore it to operation.”

Williams, who has a history with the purchasing, upgrading, and repairing of personal computers, wrote the book in order for readers to have a comprehensive one-stop resource all in one place. “The more you learn about your own computer and how to install software and hardware systems on your own, the more money you will save,” he explains.

Williams learned firsthand the value of having such knowledge at his fingertips when he completed studies in computers and other electronics for his Associate of Science degree. It is his hope that readers will find this knowledge useful as they run into everyday roadblocks with their personal computer.

Xulon Press, a division of Salem Communications, is the world’s largest Christian publisher, with more than 7,000 titles published to date. Retailers may order Williams Sundial Properties through Ingram Book Company and/or Spring Arbor Book Distributors.

Williams Sundial Properties is available online through xulonpress.com/bookstore, amazon.com, and barnesandnoble.com.

Thermaltake frío overclocking cpu cooler review

May 30th, 2010

As most of you know, Thermaltake has been making quality PC hardware thermal solutions since 1999. They have recently released some killer equipment to keep your hardware cool. From coolers to cases, Thermaltake has recently been on a marketing push for their new cooling equipment for enthusiasts and overclockers and today we take a look at their CPU air-cooler solution built specifically for overclockers – the Thermaltake Frío.

Thermaltake, leading DIY thermal solutions brand, launch their latest CPU air-cooler specifically designed for overclocking, the Thermaltake Frío. Its name is its mission, as Frío is the Spanish word for cool. With a maximum cooling capacity of up to 220W, this high-end cooler is the ideal solution for overclockers and power-users alike. The universal socket support makes it compatible to all computer processors currently available on the market.

The Frío certainly has a lot to live up to since its name is derived from the Spanish world for “Cool”. The cooler is designed to cool a maximum of 220W which puts this in the “high-end” class of coolers like the latest Zalman or Noctua for what seems to be a pretty economical price of $59.99.

This cooler is marketed for overclockers, but is really built for people such as myself who are interested in video editing as well and keeping their temperatures down. It doesn’t hurt that Thermaltake designed the Frío to look uniquely aggressive and very cool.

The cooler measures 139(L) x 98(W) x 165(H) mm and a whooping 1042 grams (almost 2.5 pounds!) is designed to support a multitude of platforms including the Intel LGA775, LGA1156, LGA 1366 and AMD AM2, AM2+, AM3 sockets – basically every current chipset on the market today.

For those of you with windows on your case, this is one CPU cooler that will not embarrass you in front of your friends at a LAN party either. Trimmed in black and red, the cooler just looks like it will keep your temperatures down. It’s quite stylish and doesn’t look like a blooming onion or flower petal.

Beyond computer literacy

May 30th, 2010

IN today’s ICT-enabled learning ecology, conventional training programmes to produce technically competent teachers are no longer adequate. To learn and work effectively in an increasingly information-rich environment, students and teachers must use ICT effectively.

The necessity for this skill has already been proposed, rationalised and justified many times over in expert journals globally.

Malaysian students have been trained and empowered to achieve important ICT skills so that learning will be self-directed, self-paced and self-accessed.

Teachers are responsible for establishing the classroom environment and preparing the learning opportunities that facilitate students’ use of technology to learn, communicate and develop knowledge. But how well are they equipped to provide their students with these skills and opportunities?

Conventionally, ICT competencies refers to the sets of basic knowledge and skills that are exhibited by a user in a digital era. Hence, various agencies within the Education Ministry have conducted training courses to equip teachers with ICT knowledge and skills.

Concurrently, teachers have also been trained at the school, district or state level, and some have learnt ICT skills on their own as part of their on-the-job-responsibilities.

Through these training programmes, the Ministry envisages that all teachers will move forward from being “computer literate” to actual users of supporting software developed by various agencies, and even capable of planning and designing effective constructive environments for students.

The question now is: what is the impact of these training initiatives among teachers? Are our main stakeholders – the students – achieving expected outcomes? Are the training models used adequate to meet today’s demands?

We propose that conventional training models be reviewed and transformed in alignment with research findings and current global demands for new learning environments.

To be equipped with technical ICT skills and knowledge is the key to effective implementation of ICT in teaching and learning, but are these sufficient to address the current ecology of ICT-enabled learning?

We surmise that training standards are as much about knowledge of curriculum and pedagogy, reflecting a shift in emphasis away from ICT as content to ICT as a tool.

A national ICT Competency Standard may serve as a reference point for development of ICT training programmes. This standard can ensure that all the trainings are of high quality and are relevant to the specific needs of teachers and students.

The following categories of ICT competencies and performance indicators should be considered as benchmarks for all ICT Training Programmes for Malaysian teachers:

·Knowledge and Skills in basic ICT tools, including productivity applications software, web browsers and learning management system.

·Planning and Designing Rich-Learning Environments to support student-centred learning among students of diverse needs, including the use of collaboration and communication tools to support problem-based learning for a community of learners (COL).

·Pedagogical strategies to develop innovative ways to encourage students’ critical and creative thinking skills, including preparation of tools, rules and roles for students in a community of learners.

·Application of ICT-enabled Assessment and Evaluation to maximise learning through self-assessments of problem-solving, communication, collaboration, creative & communication skills.

·ICT-enabled Continuing Lifelong Professional Learning, Practice and Productivity for Just-in-time learning, including active participation in knowledge communities, sustaining own lifelong development and contributing to other COL.

·Ethics and moral values surrounding the educational use of computers and software applications.

We advocate the establishment of a Malaysian ICT competency benchmark that will govern and direct the realisation of a transformed cohort of teachers who could contribute to higher quality education ­— and in turn produce a higher quality competitive workforce for the wellbeing and advancement of our economic and social development.

One of the core skills surrounding this aforementioned issue is an ability that is directly related to the rapid expansion of the World Wide Web (WWW). It requires teachers and students with superior competencies in using ICT to sieve through and choose relevant information that is available on the vast sum of human knowledge that is represented and available on the Web.

The WWW had long ago reached singularity where information is infinite. Where Web 1.0 was about information storage, we are now in Web 2.0 where collaboration and global projects are the norm (think Facebook) and fast heading into Web 3.0, where individual IQs will no longer matter. What will instead matter will be collective intelligences, which bring together the collective IQs of teams of global citizens to work on decision making processes that has at its base a collective IQ amounting to millions of points.

Is Malaysia ready for this? Are our teachers and students geared for this radical shift in thought processes and approaches to learning and problem solving? What innovation is taking place in our schools and ministry that will create opportunities for exploring and developing new, unheard of skills that will soon become essential to not just the levelling up of our talents, but to sheer survival in new marketplaces?

Where is Malaysia in the blossoming of new areas of studies in the fields of NBIC (Nano, Bio, Info and Cogno) technologies? In a world where these new areas of studies are being presented at primary and sometimes preschool levels, where does Malaysia stand in the complete overhaul and transformation of its curriculum?

Learning the new rules, new roles and new ways of a learning environment that go hand-in-hand with ICT integration requires that teachers have opportunities to participate in an extended process of professional development.

Teachers need time to acquire technology skills and develop new teaching strategies for integrating ICT into the classroom.

At present, except for occasional in-service programmes, teachers often have no time built into the school day for their own professional development.

In conclusion, it is important to ensure that all students have the opportunity to use ICT for student-centred projects. This is so that participation is enabled in complex, authentic tasks within a collaborative context and development of higher-order thinking skills will be developed and achieved.

ICT that is used for deeper learning and that support a challenging curriculum will result in improved teaching and learning, increased student motivation and higher levels of student achievement.

Although there has been a strong push to have teachers trained and to supply educational software and hardware into the hands of teachers, many obstacles to implementation still exist.

Equipment may not be placed in easily accessible locations. Hardware and software often pose problems for teachers in the classroom, and just-in-time technical support is unavailable.

Teachers may lack the time and the motivation to learn ICT skills. School administrators and the ministry must persevere to find time for teacher professional development especially with regards to the upgrading of ICT competencies for the realisation of the new learning landscape.

Small boxes, big performance routers can handle more than just WLAN

May 30th, 2010

If you are a broadband customer, you likely received a free router when you first signed up for your internet connection. Fast forward a few years and that same router is probably still plugging away at its job.

Yet those little utility boxes have seen quite a bit of technological improvement over the past few years. Purchasing a new router may well justify the expense.

First consider whether you need a router with or without an integrated modem. Entry-level WLAN routers running the current fastest standard (802.11n) are available without an integrated modem for as little as 60 dollars.

Yet if you don’t already have a modem on hand, you’ll end up having to buy one anyway. It’s not that the 20-dollar purchase price is a killer, says Andreas Nolde from computer portal chip.de. It’s the fact that hooking the two devices up to work together can be a hassle.

Complete solutions also prevent cable thickets from forming. For users looking only to surf the internet, a device with four Ethernet ports is sufficient.

Those needing better performance will want devices with the faster Gigabit Ethernet technology, says Thomas Jell from hardware maker Netgear in Munich. Data travels up to ten times faster, quick enough even for the needs of gamers.

Dual band is one interesting optional feature: It means the wireless network can be set up to work with either the commonly used 2.4 Gigahertz signal frequency or the relatively little-used 5- Gigaherzt range. In residential complexes where many WLAN routers are running in close proximity, the 2.4 Ghz range can become overloaded.

Switching over to the 5 Ghz range can be like switching onto an empty highway. One important point: not just the router, but rather all devices on the home network have to be compatible with both radio bandwidths.

The fastest WLAN standard is known as 802.11n and permits transfer speeds of up to 300 megabits per second (MBit/s), although those numbers are a theoretical best maximum throughput. Practical experience shows that home network use tends to produce much slower speeds.

The routers provided by broadband providers differ from store- bought devices primarily through configurability, says Thomas Trau from PC-Welt magazine.

Simple routers tend to hit their limits fast if larger data volumes need to be sent through the network; if devices like printers or USB ports need to be integrated; or even if the internet signal needs to move across more than one floor.

The routers delivered for free by broadband providers usually fall into that category. They will also almost certainly become bogged down by overly high traffic volumes, such as if four users are trying to download data at the same time.

Trau recommends checking before you buy a new WLAN router based on the n-standard to ensure that all of your devices, including PCs and internet radios, can work with that standard. If the computer can only handle the older 802.11g standard, for example, then the router will be unable to take advantage of its higher speeds. On the other hand, 802.11n WLAN can typically beam to a wider broadcast area.

Some routers also support internet telephony and incorporate telephone equipment into the network. Trau highly recommends this function. That is also helpful for smartphones: the iPhone, Android- OS phones, and others can do more using a home WLAN net than when on the go, says Urban Bastert from router maker AVM.

“Once you have linked in to the router, you can phone using the home connection and save money,” Bastert says. Or you can use a WLAN-ready mobile phone to retrieve emails or check a Facebook profile.

Good routers also include a built-in media server. This provides users access to data on external hard drives attached to the home network, even if the PC is switched off. A router supporting the UPnP networking standard can also permit streaming audio and video files.

Better routers also include special energy-saver functions: “USB hard drives connected to the router should be able to go into sleep mode and only run when needed,” Bastert says. The experts call this spin down: when the router is inactive, the USB storage powers down and only wakes back up when it’s needed.

HTC mytouch 3g slide for t-mobile review

May 30th, 2010

When T-Mobile announced the myTouch 3G, it was almost immediately welcomed warmly into the Android family. With the exception of, perhaps, the name, the myTouch 3G saw a wide adoption, as people jumped on board the Android train. And now that it’s been out for some time, and it’s seen a couple of “refreshes,” T-Mobile and HTC have seen fit to add a new model to the family. So here we are with the myTouch 3G Slide, which adds a bigger screen, a bit more bulk, and a physical keyboard. But, with all those additions, does the Slide hit the nail right on the head, or is it not enough to be a warm new welcome to the family name? Find out below.

The first time you pull the myTouch 3G Slide out of the box, the first thing you’ll notice (with the battery installed), the phone is heavy. And, given the plastic aesthetic to the device, it can be quite deceiving. However, past that initial shock, the phone actually feels quite nice in the hand. The added bulk (due primarily because of the hardware keyboard) and weight go a long way to make the phone feel more reliable and sturdy. As for the general look of the device, it’s almost identical to the original myTouch: the curves, lines, and even the general feel of the device feels reminiscent in a very good way. The main differences would be the hardware keys just below the screen, and the inclusion of an optical trackpad (we’ll cover these a little later). Truth be told, the device is very pocketable.

Taking the device in your hand, you’ll notice that the Slide fits right in with other touchscreen devices: the 3.4-inch display takes up the majority of room, leaving just enough space for the earpiece and “myTouch” logo at the top, and the standard Android-based physical buttons. The screen’s resolution is 320×480, but don’t let that fool you: the colors (especially when the screen’s brightness is all the way up) are fantastic. We know that has a lot to do with the customized User Interface, and its closeness to HTC’s Sense UI, but we can’t sit here and tell you that the screen’s size or resolution are a bad thing. In fact, we enjoyed both of them a great deal, and felt that the 0.2-inch difference between the original myTouch 3G and the Slide is a great (and much needed) improvement.

Unfortunately, its these physical keys that put a big damper on the general good feeling of the Slide. They’re shoved between the screen and curved bottom edge of the device, but they’re actually flush and not raised at all, making it somewhat difficult to press them if you’re not actively paying attention. Furthermore, they have very poor feedback and travel, and they’re lack of separation from one another makes it easy to hit the wrong button in your efforts. It should also be noted that there’s actually not a Search key. Instead, T-Mobile and HTC decided to focus on the “genius” button, which we’ll cover a little later. But we will say that we found ourselves wanting the Search key back, as we didn’t use the genius key nearly as much.

As has happened with every other major handset release from HTC, the company has decided to drop their trackballs, and adopt the optical trackpad. The Slide features one of the best we’ve ever used, as its responsive, and big enough that using it isn’t a pain. However, we will say that HTC’s decision to also make it flush with the handset, and therefore make it feel just like one of the hardware buttons was a mistake. It’s very easy to hit the trackpad instead of Back or Menu, or vice versa, which causes undue stress and frustration.

Intel to release dedicated tablet processors next month

May 30th, 2010

Intel has promised, together with the unveiling of the ultra-low voltage 32nm processors, to launch processors optimized for tablets. The chips were not detailed but they are expected to debut at the Computex show that starts on the 1st of June. It is believed to be a variant of the Atom Z600 processor, with speed and energy tuned for larger hardware, other than phones or mobile Internet devices.

Intel has been struggling for being accepted in the tablet world, because its processors were too power-hungry and in some occasions too slow if compared to ARM. The Windows 7 tablet would be equipped with a conventional Atom processor, even if an older model. If shipped, it would have only five hours of use, while a thinner iPad normally lasts twice as long. Intel’s choice relative to integrated graphics has until now avoided high definition video playback and 3D gaming as well, both of them being possible on ARM hardware, be it Apple or dual-core Tegra tablets. This may have been enough for Hewlett Packard to cancel its project for the Windows slate, although rumors have said this would not be true.

Atom is believed to get its best chances at tablets next year, as 32nm and perhaps smaller manufacturing technologies can preserve its energy level and size to figures comparable to ARM levels.

Resolving Bluescreens in Windows 2008 R2 on Nehalem Processors

May 29th, 2010

I was having nothing but problems with a new server, the system wouldn’t last more than 2 minutes without bluescreening, a phenomenon I hadn’t seen since the old Windows NT days, I was having very bad flashbacks…. I did the typical problem solving by flashing the system bios with the latest bios the hardware vendor had on their site, unloaded anything slightly squirrelly I had loaded up on the system, stripped it down to just Windows 2008 R2, but still, within a couple minutes while my HyperV guest sessions were loading up, the system would bluescreen. Got the point where I was pretty certain it wasn’t my configuration…

I stumbled across a Microsoft knowledgebase KB article that wasn’t exactly what I was having the problem with, but pretty close. Basically there is a “known bug” with Windows 2008R2 with Nehalem processors (which the system I was working on had an Intel Nehalem i780 processor). The KB article is http://support.microsoft.com/kb/975530 which I downloaded the hotfix (had to do it in Safe Mode with Networking as I couldn’t even keep the server going long enough to download the hotfix without bluescreening) finally got the hotfix loaded, thing has run like a champ ever since…

I’ve setup hundreds of Windows 2008 R2 HyperV hosts, but this was the first server of the new Nehalem processor that I had, and while I had some intermittent blue screen problems on another similarly configured system, this system wouldn’t run for more than a couple minutes, long enough for me to take a photo of the screen (which in the past went so quickly that I couldn’t read the error to properly diagnose and fix the thing).
With the installation of the hotfix, ALL bluescreen problems/issues have completed disappeared.
