Laptop AC Adapter – A Brief Overview

A laptop AC adapter is perhaps one of the most important accessories your laptop needs to have to make it useable while it is on the move. Like most other accessories you’ll find along with your laptop, AC adapters have got their own role to play. in fact, these adapters are pretty much like battery chargers for your laptop.

Being an important gadget you should not find it tough to spot a laptop AC adapter. without this accessory your laptop would not function properly. At times you would have noticed power fluctuations happening regularly at your workplace. During these times, it will make sense in disconnecting the regular power supply to your laptop and run it with your AC adapter until its battery gets charged completely. without the aid of this accessory, you may need to switch off your laptop and search for another device to work on. however, this would not be a great idea as your original files could still be stored in your laptop.

If your existing laptop runs out of power and you don’t have an adapter you could risk missing out on your deadlines. just like any other accessory, these adapters can malfunction at any time and hence you need to ensure that they’re in working condition at any given point in time. else, you may have to repair the laptop AC adapter or get a new one altogether.

In having an efficient AC adapter at your disposal you can easily take your laptop wherever you go and maintain continuity in your job. but here again, you need to be careful regarding the input voltage you’ll be using for your device. not all countries have same range of voltage for operating devices. you need to ensure that your adapter is a flexible one and can operate at different voltage ranges. these are some of the details you need to pick up with the manufacturer of these laptop accessories.

You also need to make sure that other devices are in working condition and not just your AC adapter. This is because the performance of other devices can have an impact on your laptop AC adapter. hence, your adapter will work just fine only when other devices are in excellent working condition. some of the common problems you may encounter with your adapter could be related to wire bending, age and temperature changes. if the usage pattern of your adapter is fine, it will work for a long time without any problem. else, it could be a problematic device for you.

How Does a Motherboard Work?

Motherboard represents the main circuit board inside your computer. different types of control through which peripheral devices like hard drive, keyboard, and monitor. in addition to controlling these devices motherboard accommodates connectors for attaching more peripherals or expansion slots for your PC. Motherboard can be defined as a area where a number of activities takes place and hence it is important to understand different technical terms associated with it.

1. AGP: - Accelerated graphics port refers to an expansion slot. It is considered as a successor to PCI and meant to speed up data transfers related to video cards. Newer computers are known to use more flexible and faster types of these slots for video cards.

2. Device driver: - It refers to software that facilitates easy access to a small hardware.

3. Display Adapter: - It is a hardware that is responsible for displaying images on monitor. the term can however be applied to both integrated graphics and video cards.

4. Connector header: - It refers to a series of metal pins that is present on a motherboard. It is used to connect cable with switches, indicator lights and other devices on your computer.

5. Jumper: - It refers to a small electronic interconnect or a small block that can be used to select, enable or disable operating parameters present on your motherboard.

6. BIOS: - It refers to built-in software in your computer that is capable of determining what it can do without accessing appropriate programs from the disk. BIOS are equipped with necessary codes that can be used to control display screen, keyboard, serial communications, disk drives and others.

7. Cable set: - It includes one or more interface cables. in the case of motherboards, these sets include cables for hard drive, floppy drive, and CD-ROM drive.

8. Chipset: - It refers to integrated circuits that control the interfaces between the RAM, system processor, adapter cards, and I/O devices.

9. Processor slot/socket: - It is here the system processor is mounted on your computer.

10. ISA: - It is the acronym for Industry Standard Architecture. It is a slow speed interface that can be used for modems and sound cards. It generally runs at 8MHz.

11. USB: - It is the acronym for Universal Serial Bus. It is a medium speed interface that is used for keyboards, mice, display panels, scanners, and digital cameras.

12. SCSI: - It refers to Small Computer System Interface. It acts as an interface between SCSI controller and internal or external SCSI device.

13. VGA: - It Stands for Video Graphics Adapter. It is the interface between integrated video connector or video card and display monitor.

14. Driver: - It refers to software that is used for determining the characteristics of devices for use by another software or device.

15.ACPI: - It is the acronym for Advanced Configuration and Power Interface. a specification developed by Microsoft, Toshiba and Intel for power management. It enables the operating system to entirely control the power supplied to different components or devices attached to your computer.

Mayor Enters New Urbanist Lion's Den

It fills in a failed urban renewal highway. does that make it “new urbanism”?

That question has hovered above new Haven’s biggest development project in a generation, Downtown Crossing. Another way of asking the question: Is new Haven undoing a major mistake and learning from its past? Or is it repeating the mistake?

Mayor John DeStefano traveled to West Palm Beach, Florida, to try convince his toughest skeptics that new Haven has learned, that new Haven is rebuilding community and neighborhood and a lively streetscape where bulldozers once killed them. he spoke by invitation on a panel at a conference organized by a group called the Congress For The new Urbanism.

He earned points from the skeptics for showing up and making his case. he didn’t win many converts.

“with all due respect mr. Mayor,” asked one participant, a designer from California, “what the fuck were you thinking?”

Here’s what DeStefano was and is thinking, he told the group: “Don’t let the perfect be the enemy of the good.”

The “good” he referred to was Downtown Crossing, phase one of which is before the Board of Aldermen for approval.

Under the plan, DeStefano is hoping to fill in the Route 34 Connector mini-highway-to-nowhere that slashed through downtown a half-century ago during the height of urban renewal. The dream then was to connect commuters from I-95 to the Naugatuck Valley. It was called the “Oak Street Connector” though it was more like an Oak Street Eviscerator. And it was never finished. In the end, it just went three blocks—but helped destroy a neighborhood and separate downtown from the Hill.

The city hopes to begin its rebuilding effort by filling in the block nearest to the Air Rights Garage and having developer Carter Winstanley build a 10-story biomedical office building. That phase should cost $140 million, including Winstanley’s building and government-backed road changes.

At first blush, the enterprise seems to typify the “new Urbanist” creed. That philosophy calls for reversing the strategy of mid-20th century urban renewal (of which new Haven is the most concentrated example). Instead of large single-use modern buildings and highways and car-centric street grids, new Urbanism combines stores, apartments, green spaces, offices, all together on a human scale with a walkable and bikeable streetscape and narrow, slow-moving two-way roads. Downtown Crossing was originally sold as a way to stitch back together the Hill and downtown, with an emphasis on pedestrians and active street life.

by the time it came up for approvals, it featured the 10-story office building (pictured) with five lanes of one-way traffic and no new cross streets. Critics saw a new highway replacing an old highway, with endless cars and a corporate island keeping neighborhoods apart and people away. Officials estimate Downtown Crossing will bring the city hundreds of new jobs and more than $1 million in new annual tax revenue.

Click here and here and here to read some previous stories outlining that criticism. And click here to read a critical analysis released by new Haven’s Urban Design League.

That criticism spread from new Haven to the Congress for a new Urbanism, a national group. The group invited DeStefano down to an annual conference in Florida last week—and he accepted.

He knew to expect criticism. he hadn’t realized he would walk into a lion’s den.

He was one of four scheduled panelists to address a 2 p.m. breakout session called “Urban Freeways: Devastation and Opportunity.” new Haven was one of several examples of cities tackling “urban freeways [that] destroyed traditional, often poor, neighborhoods” and exploring how “to repair the urban fabric and make cities whole again.”

The mayor brought along a 19-slide PowerPoint presentation entitled “A Dream Comes true!” It began with the picture at the top of this article. Then-Mayor Dick Lee, the father of new Haven’s nationally watched urban renewal, distributed it as part of a 1959 campaign brochure to argue that he was remaking the city in a smart way to create jobs.

On the subject of the highway, DeStefano agrees with the new urbanists: It was a mistake.

“they thought the highway was the dream,” DeStefano said of the Lee administration planners in a subsequent conversation about his Friday presentation. they had rundown homes torn down all over town to make way for progress—including a home on East Street where the DeStefano family lived.

“Highways were used as slum clearance. We didn’t know we lived in a slum. We didn’t live in a slum. It was a three-family house with a lot of people,” DeStefano said.

He noted that the circled numbers in the flyer pointed to new buildings where new jobs beckoned: the George Street phone company headquarters, the College Plaza, the former Channel 8 retail plaza. The mayor made two observations about that. One: The planners saw transportation policy as a way to make way for new jobs. And two: all those locations have now morphed into medical-related labs and offices or Yale-owned space. “Eds and meds”—education and medical-related development, the current engine of new Haven’s job-creation strategy.

In other words, times change. And new Haven is rebuilding that area with new jobs in mind. We can learn from the past and still aim high the way the city did then.

“they were very smart and very competent and did a lot of great things. Dick [Lee] said, ‘our goals were great, so too were our failures,” DeStefano said.

DeStefano also offered a slide (pictured) of how the city envisions the larger area developing over time as the highway fills in.

Other members of DeStefano’s panel discussed Boston’s Big Dig and Miami’s Overtown Expressway. When it came time for audience questions, almost all the attention turned to DeStefano and new Haven’s Downtown Crossing.

The participant asking the expletive-enhanced question quoted higher up in this story was R. John Anderson, founder of a Chico, California, architecture and design firm and a prominent new Urbanism proponent.

“We should not let the lame be the enemy of the perfectly adequate,” Anderson told DeStefano, according to notes taken by another new Havener present, Philip Langdon.

DeStefano’s reply: “You have no money on the table.” In other words: That’s nice in theory, but the city has to deal with practical realities like investment and revenue and the existing streetscape.

In his presentation, the mayor emphasized that the city has other priorities beyond design, such as school reform, job-creation and public safety. he also noted that his administration obtained 121 variances from Connecticut’s transportation department in the design to accommodate design concerns, including reducing travel lanes to 10 feet wide.

New Haven’s Langdon said he came away with the conclusion that the Dick Lee campaign brochure was an unintentionally apt choice for the mayor’s presentation: “The mayor is more in the Dick Lee tradition than he realizes.”

Anderson said Monday that he didn’t find the mayor’s response—that the city put together an important job-creation project that is worth pursuing even if it’s not perfect—convincing. he called Downtown Crossing as currently designed an “epic mistake.”

“I did tell the mayor that I believe he is making a huge mistake in making a lame project the enemy of a perfectly good project. by not reconnecting the street grid and leaving the grade separation, he is wasting the potential for future private investment in a high value area that can reconnect the medical district with downtown and the surrounding neighborhood,” Anderson wrote in an email message.

“The tone of the mayor’s remarks was that he had done all that could be done and the grown-ups had decided that half a loaf was better than none. The plan that mayor is pushing is breathtakingly stupid because it does not deliver even half a loaf. … I regret that I could not be more polite in my remarks following the mayor’s presentation, but we were all watching him blithely wander off into oncoming traffic. I hope that he will not continue on his current course.”

Norman Garrick, a UConn professor, praised DeStefano for showing up.

“I was real impressed that he did come. People had a different perspective of what we need to do,” Garrick said in a conversation Monday. “he got almost all the questions. It was people trying to get across a different design.”

Garrick’s takeaway from the event: “It doesn’t seem from their [the city’s] plan that they’re [really] losing the highway.

“What they’re building including the Winstanley building seems like a continuation of the suburbanization … It’s a big box. It’s a lot of cars. It’s not integrated with the neighborhood.”

DeStefano’s takeaway from the event: The designers in the audience don’t operate in the real world.

“We are removing a six-lane limited express highway. And their arguments had to do with number of turn lanes and lane width. It is fundamentally different than what is there now. To me the idea that somehow this is not an incredible departure is removed from any meaningful sense of reality,” DeStefano said Monday. “they just ignore any real discussion of budget constraints, any real grounding.”

For instance, DeStefano said, participants argued that the loading docks for the Smilow Cancer Hospital and other nearby facilities should return to street grade. (The city moved them to below the Air Rights Garage.) he said that would create a broad range of new traffic and safety problems. Similarly, he said, participants pointed to the three lanes of traffic coming off I-91 at Trumbull Street as an example of how Frontage Road could work coming off the highway. “We have ten times as much traffic” there than at Trumbull Street, he said.

“I don’t have a green field [to build on from scratch],” DeStefano said. “I have an imperfect world that I’m trying to make it better. this makes it better. It’s an abstract exercise for them.”

In the end, despite some discussion he considered “bizarre to the extreme,” the mayor said he’s glad he ventured into the new Urbanist lion’s den.

“I love designers. But right now we’ve got this huge opportunity to do this project,” he said.

“I wish I was able to satisfy every person every way they’d like. I think that’s hard to do sometimes. I also think it’s good to have people prodding you and pushing you even though you find it annoying. What do we learn more from—our accomplishments, or our mistakes?”

Dell feeds Xeon E5s to hungry new PowerEdge beasts • The Register

Dell has added nine new Xeon E5-powered boxes to its PowerEdge 12G lineup as it chases the booming market for quad-socket machines in Asia.

These latest workhorses use Intel’s new Xeon E5-2400 processors for two-socket servers and the E5-4600 for four-socket servers, and will add to the five rack, tower, and blade servers and one C6220 cloudy box that Dell announced in February before the Xeon E5-2600 launch.

Rather than jump the gun on Intel again, Dell waited until the chip giant actually launched the silicon to talk about the nine new machines that will ship in may and June. and the theme behind most of the new machines is the same: increased density, whether it is a rack, a blade, or a tower box.

There are three new PowerEdge racks, three new blades, and two towers. Let’s do the racks first because these are the volume products in the X86 server racket these days: they are the PowerEdge R320, R420, R520, and R820, with the first three based on the Xeon E5-2400 and the latter one based on the E5-4600.

The PowerEdge R320 is a single-socket rackable 1U box that also supports the Xeon E5-1410 and the Pentium 1400 series. The server is based on the “Patsburg” C600 series chipset, like all Xeon E5 machines are, and it comes with six memory slots for a maximum of 96GB of main memory if you splash out on 16GB DDR3 memory sticks. The machine has one x16 and one x8 PCI-Express slot, and presumably these are 3.0 slots matching the peripheral controller on the E5-2400 chip. (The spec sheet from Dell is not explicit.) The R320 12G machine has room for four 3.5-inch disks or eight 2.5-inch disks and has an embedded Broadcom dual-port gigabit Ethernet interface on the mobo.

The PowerEdge R420 12G machine is a two-socket box that double-stuffs the 1U rack chassis with Xeon E5-2400 CPUs. it uses the same C600 chipset, and has a dozen memory slots for a total of 192GB of RAM using the top-end 16GB DDR3 memory sticks. The PCI-Express 3.0 slots vary depending on how many CPUs you put in the box. With one CPU, you get one x8 (with x4 of bandwidth) and one x16 slot, but with two CPUs, you get two full-on x16 slots; you have the same disk options and dual-port Ethernet on the board that the R320 12G has.

With the PowerEdge R520 12G, you get a two-socket mobo with the same CPU and memory options of the R420 12G in a 2U rack chassis and then let it have some more peripheral slots and disk expansion. so you have the same 192GB RAM max across a dozen memory slots and dual-port gigabit Ethernet ports. but now you can have up to eight 3.5-inch disks; the spec sheets say it supports 2.5-inch disks but does not say how many, so we presume it is sixteen. With both processors in the box and both PCI-Express 3.0 controllers fired up, you get four x16 slots, one running at the full x16 speed and the other three with x8 bandwidth.

Brian Payne, executive director of PowerEdge marketing at Dell, told El Reg that the R420 and R520 machines are only 24 inches deep instead of the 29 inches or 30 inches of depth that a typical rack server has. This means they can be used in a variety of telecommunications and military applications where racks tend to be more shallow because physical space in data centres in scarce.

Dell's PowerEdge R820

Dell’s PowerEdge R820 four socket racker

The PowerEdge R820 12G machine keeps the same 2U chassis, but crams four of the E5-4600 processors into the machine and sports up to 48 DDR3 memory slots for a maximum of 1.5TB of main memory using 32GB sticks. Dell supports up to sixteen 2.5-inch drives on this machine (but no 3.5-inch drives apparently) and a variety of embedded network controllers that snap into the mobo, including a dual-port Broadcom gigabit, a quad-port Intel gigabit, a dual-port Intel 10GBaseT, and a dual-port Broadcom 10-gigabit SFP+ with two gigabit ports on it as well.

Payne said the PowerEdge R820 12G is ideal as a database engine and he expects a strong uptake for server virtualization as well. The R820 has been shipping to early adopter customers for some time now, but not on the scale of the early shipping that Intel did with the E5-2600s last autumn and early winter.

Officially these four rack servers will start shipping in may, but none of the pricing and exact feeds and speeds for processor options are available yet. these new PowerEdge rack machines support Microsoft’s Windows Server 2008 R2 SP1 as well as Small Business Server 2011, Red Hat’s Enterprise Linux, and SUSE Linux’s Enterprise Server; Microsoft’s Hyper-V, Citrix Systems’ XenServer, and VMware’s ESXi hypervisors are also supported on the machines.

Blades still cut it for some customers

Dell has three new blade servers for its M1000e chassis that come out today using Intel’s latest Xeon E5 chips.

The most interesting of them, and one that brings Dell to the same level of server density in its blades that rival Hewlett-Packard has been offering for some time with its SL-6500 modular servers, is the PowerEdge M420 12G. This is the quarter-height blade that Dell was brandishing back in February in wave one of its PowerEdge 12G launch. (Today is technically known as wave two, and it is about bringing “value priced” two-socket and four-socket boxes out.)

The M420 slides into the M1000e chassis and you can stack them up four high and eight wide for a total of 32 two-socket E5-2400 blades in the 10U chassis. That’s up to 2,048 cores in a rack.

Dell

Four Dell PowerEdge M420 blades in a pod

The M420 server blade has two processor sockets and it is not clear what E5-2400 SKUs are supported in the blade yet. The blade has six memory slots, for a top memory capacity of 192GB per node using 32GB memory modules. Each blade has two USB ports on the front and two slots for hot-plug 1.8-inch SATA SSDs that come in either 50GB or 200GB capacities. The M420 has a slew of mezzanine card options to support links to gigabit Ethernet, 10GE, InfiniBand, and Fibre Channel switches. The most important stats for networking is that this blade can have four 10GE ports or one 56Gb/sec FDR InfiniBand port.

The M520 blade takes up a normal half-height, single-wide slot in the M1000e chassis and is also a two-socket machine based on the E5-2400, but has a dozen memory slots and a maximum of 192GB of capacity using 16GB DDR3 sticks. This blade uses the normal 2.5-inch SAS and SATA drives and SSD options in the PowerEdge line. it has a mix of Ethernet and Fibre Channel mezz cards, including 10GE cards that support Fibre Channel over Ethernet, but interestingly, the M520 does not offer an InfiniBand mezz card. (Go figure.)

Both the M420 and M520 12G blades will be available in may and support the same OS and hypervisor mixes as the rack servers above. As with the rack machines, Dell has not put out pricing yet, even though it is taking orders.

The PowerEdge M820 won’t start shipping until June, and it is a full height, four-socket blade that employs the Xeon E5-4600 processor. like its R820 brother, the M820 sports 48 memory slots, for a total of 1.5TB of main memory if you use the fattest DDR3 sticks. it has room for four 2.5-inch disks or SSDs, and can also have two Express Flash flash modules that link into the PCI-Express 3.0 bus on the server. and perhaps importantly for HPC and database cluster customers looking for fat nodes in a blade form factor, the M820 has InfiniBand mezz cards (DDR, QDR, and FDR speeds are available) as well as the usual 1GE, 10GE, and Fibre Channel cards. You can’t run Small Biz Server 2011 on this one, but Windows Server 2008 R2 SP1, RHEL 6, and SLES 11 can run on it, as can the usual hypervisor suspects (minus Red Hat’s KVM).

Tower of power

That leaves the two entry tower machines based on the Xeon E5-2400 processors in wave two of the PowerEdge 12G rollout: the T320 and the T420.

As you might expect from the naming conventions, the PowerEdge T320 tower server is similar to the R320 in terms of its basic feeds and speeds, supporting a single E5-2400, E5-1410, or Pentium 1400 processor, 96GB of max memory, and linking to the outside world through the C600 chipset. but the T320 12G server has more IO expansion with five PCI-Express 3.0 slots:­ one x16, three x8 slots with x4 bandwidth and one x8 slot with x1 bandwidth. The machine has room for eight hot-plug 3.5-inch or sixteen 2.5-inch drives and has a dual-port gigabit Ethernet NIC on the mobo.

Dell's PowerEdge T320 and T420 towers

The T420 is a two-socket mobo based on the E5-2400 slipped into the same chassis, with 192GB of max memory and six PCI-Express 3.0 slots: two x16 slots and four x8 slots (with geared down bandwidth on all of the x8 slots). The T420 has the same disk and network options and from the outside you could not tell the difference between the two machines.

Both of these E5-2400 tower machines are positioned as workstation alternatives with optional Quadro 4000 or 6000 series discrete graphics cards, and therefore compete somewhat with Dell’s Precision workstations.

When Dell gets pricing information out, we’ll circle back and see what this stuff costs. all that we know right now is that the machines are “value priced” compared to the E5-2600 and E7 alternatives, but doesn’t really help that much. ®

College Softball: Texas State caps perfect home record in conference » Sports » San Marcos Record, San Marcos, TX

San Marcos — Every bit of momentum helps in a single game, but in a doubleheader, it probably counts twice as much. Texas State wrapped up its conference home schedule Tuesday night with a pair of games against its arch-rival Texas-San Antonio. A game-winning double by freshman infielder Courtney Harris gave the Bobcats a win in the first game (2-1), then rode the wave to an easy win in the second (6-3), sweeping the Roadrunners. With the wins, Texas State finished undefeated in conference home games, posting a 10-0 record. “It’s always good to win at home,” Harris said. “you never want somebody to come here and beat you, so we do a good job of protecting our house.” after two hours of play in the first game of the doubleheader, the Bobcats’ unblemished record looked to be in peril despite senior pitcher Chandler Hall’s best efforts at the plate and in the circle. Hall collected Texas State’s only two hits before the 10th inning and tried her best to keep UTSA off the scoreboard. She held the Roadrunners without a run through nine innings, escaped several tough jams (two on with two outs in the fourth and eighth) and tied a career high with 13 strikeouts (six after the sixth). “sometimes as the game goes on, I feel like I throw the ball a lot harder since I know I need to use my body a lot more, because my arm starts getting tired and stuff,” Hall said. “As the game wears on, I do get stronger — which is good — especially in a game like this.” when Hall stepped out of the circle for the final time at home, she had thrown 163 pitches (114 strikes). She had to rely, however, on a struggling offense to get her an 18th win — or back on the field in the 11th. The Bobcats couldn’t find a way to dent the armor of Hall’s counterpart, Haylee Staton. Texas State either jumped ahead of Staton’s drop ball or was powerless against her riser, popping out 13 times in addition to nine ground outs. Harris made solid contact each time up, including a line out in the bottom of the seventh with Hall on second. even though it ended the inning, Harris promised herself that she’d get another chance. “I did want to get another at-bat,” Harris said. “It sucks when you hit a hard ball right at someone. there is nothing you can do about it.” Harris wouldn’t let anybody touch the product of her next at-bat in the 10th inning, as she lined a double to the wall in left-center field. Junior first baseman Haley Lemons, who was placed on second due to the International run Rule, easily scored and Harris had to coax Hall (who reached on a walk) home in her mind. “I was just trying to hit it hard,” Harris said. “The whole time I was just thinking, ‘Chandler, run,’ because she had to score from first. She did and we won.” The Bobcats used the momentum from Harris’ game-winning hit to propel themselves to a big lead in the second game. Texas State pushed two runs across the plate in the second inning on a two-run, two-out double by sophomore outfielder Jordan Masek, then added four more on five hits in the fifth. Hall delivered her third hit of the night to knock in one of the runs and two batters later, fellow senior Allison Snow roped a two-run double to cap the Bobcats’ scoring. “That’s what we talked about [between games] was that they were kind of down, so let’s jump on them early if we get the chance,” Texas State head coach Ricci Woodard said. “It’s always a good thing when you see your team do what you’ve asked them to do.”

Mozilla product director says Firefox on Window RT 'probably not worth it'

A Mozilla product director yesterday said that unless Microsoft allows other browser makers to call important APIs in Windows RT, it is “probably not worth it to even bother” building a version of Firefox for the new operating system.

In a Wednesday post to his personal blog, Asa Dotzler, product director of Firefox, again slammed Microsoft for not allowing third-party browsers access to Win32 APIs, or application programming interfaces, in the upcoming Windows RT.

Windows RT, once called Windows on ARM, or WOA, is the operating system Microsoft is developing for devices — tablets primarily, but also lightweight laptops — that rely on processors designed for the ARM architecture.

“If we built Firefox for Windows ARM Metro, we would not have access to those powerful Win32 APIs and so we would be at an extreme disadvantage when compared to IE10 for Metro,” said Dotzler yesterday, referring to Microsoft’s own browser, which will be able to call the banned APIs.

“We could build a beautiful Firefox that looked really nice on Metro, but Firefox would be so crippled in terms of power and speed that it’s probably not worth it to even bother,” Dotzler added. “No sane user would want to surf today’s Web and use today’s modern websites with that kind of crippled browser.”

Although Dotzler’s “not worth it” comment may hint at the likelihood that Mozilla will step away from Windows RT, it is not the company’s official position.

Last week, Harvey Anderson, Mozilla’s chief counsel, said that company engineers were “still evaluating the best course of action” to take with Windows RT.

Anderson and Dotzler took to the Web last week to publicly knock Microsoft for barring third-party developers access to the Win32 APIs in Windows RT, and for letting its own software, especially IE10, call those same APIs.

Mozilla’s contention has been that without the Win32 APIs, a Metro-style browser in Windows RT would be a pale shadow of its traditional Windows version. it would certainly not be competitive with IE10, in large part because it could not use a just-in-time (JIT) JavaScript compiler.

All the major browsers now feature a JIT compiler to quickly compose JavaScript code retrieved from websites and Web apps.

Under Microsoft’s current rules for Windows RT, only IE10 will be allowed to call the APIs necessary to execute a JIT compiler.

“Without [a JIT compiler] modern websites like Facebook, Twitter and Gmail would be painfully slow for users, unusably slow [emphasis in original],” Dotzler said.

Microsoft originally had a similar restriction in place on Windows 8, the more traditional operating system for x86/64 processors like those made by Intel and AMD, but relaxed the API-access rules there in February.

At that time, Microsoft issued some basic documentation that put browsers in a special category on Windows 8, and showed how developers could access the Win32 APIs from Metro versions of their applications.

Mozilla and Google, which makes Chrome, have both said they will create a browser that runs in the Metro environment on Windows 8; those Metro-app versions will call the Win32 APIs from the traditional desktop side of the OS.

Dotzler argued that Microsoft should do the same in Windows RT.

“Microsoft can solve this problem for Windows on ARM the exact same way they solved it for Windows on Intel. they can give third-party browsers the same access they give Internet Explorer,” said Dotzler.

Microsoft has repeatedly declined to comment on Mozilla’s allegations concerning API access in Windows RT. Google has said it stands with Mozilla on the issue.

European Union antitrust regulator have made it clear that Windows 8 must abide by a 2009 deal that requires the operating system to offer users a choice of browsers other than IE. Those regulators, however, but have not made the same assertion for Windows RT.

Microsoft stepped out from under most U.S. government scrutiny related to the case in 2007.

Students create life-saving digital stethoscope

A digital stethoscope, which uses a smartphone and the Cloud, could save thousands of children’s lives in developing countries.

The stethoscope has been created by four university students from Victoria for the Imagine Cup, which challenges students around the world to develop unique products using technology.

The creators of the digital stethoscope, Team StethoCloud, include Hon Weng Chong, Andrew Lin, Kim Ramchen and Masha Salehi, and they are hoping the product can be readily used in developing countries.

“The idea behind this is that due to the rapid proliferation of mobile phone technology in developing countries, such as India and Africa, and the mobile phone being a readily accessible, we can then harness the availability of the technology [to help reduce childhood mortality],” Weng Chong tells Computerworld Australia.

“They already have this technology and hopefully every village chief would have a mobile phone or every town centre where someone could bring the child in and have the application diagnose them.”

The product also has potential applications in countries like Australia where rural residents could utilise the product.

How it works

The team has taken a traditional stethoscope and embedded a microphone in the head. A wire is threaded through tubing and a 4.5mm stereo jack has been attached to the end, which is plugged into a smartphone’s microphone inline connector.

“What you do is you take the stethoscope, you place it on the back and there are six locations [which you record], because in medicine that’s how a doctor would listen to you. We take a five-second recording in each of these spots,” Weng Chong says.

“We take all of these recordings, we store them temporarily in a cache on the phone and once it’s all done, we can upload it to the Cloud. this is actually running our infrastructure on Azure right now.”

Users answer a series of questions from the World Health Organisation guidelines for pneumonia which are asked before taking the recording. The application includes videos which show symptoms that healthcare workers may not be familiar with and gives an explanation of the symptom and what it looks like.

The audio recordings are then run against algorithms to detect respiratory rate and three diagnoses are returned – no pneumonia, pneumonia and severe pneumonia. A treatment plan is then provided.

While the prototype application currently only operates on Wi-Fi or 3G connectivity, the team is developing the application to operate offline.

“Because this plugs into the phone and it acts like an inline microphone, the idea is that we can use this to call up our server that’s running a Skype gateway. it then transmits the audio signals that we have coming in as a phone call,” Weng Chong says.

“That then transmits it as an audio file across to our server and all the textural data will be sent as a SMS. We then do all the computation as we would, but instead of pushing the result back by 3G, we push it back as a SMS.”

It also only currently runs on Windows phones, but Weng Chong says it may also be developed for Android phones. however, there are no plans to integrate the product with iPhones. “You won’t find any iPhones in developing countries,” Weng Chong says.

The digital stethoscope costs about $30 to make — about $25 for the stethoscope head, $3 for the stereo jack and $2 for the microphone —and can be made as cheaply as $15 to $20. this compares to other stethoscopes on the market that are about $400 to $800 for digital stethoscopes and $200 for traditional stethoscopes, Weng Chong points out.

One key to making the product accessible financially is the digital sound processor which is used to digitise the recordings, as opposed to digital stethoscopes which embed a chip inside the head of the stethoscope and costs several hundred dollars, according to Weng Chong.

Future plans

Weng Chong says he would like to improve the stethoscope by embedding better microphones which are smaller, more sensitive, cancel noise and more uni-directional.

“We’re also writing up a research protocol to start doing some live trials on patients at the children’s hospital in Melbourne, so we believe the key is to have lots of data, and we want to do it in a controlled setting where we’re just collecting samples,” Weng Chong says.

Ramchen, who has helped with developing the algorithm for the stethoscope, says it currently has about 80 per cent accuracy in a quiet room. About 17 per cent of the time the results will be inconclusive and 3 per cent of the time it will slightly over estimate results.

He says carrying out multiple samples can help achieve more accurate results and the team is working on improving the hardware and algorithms.

Eventually they would like to include big Data in the application and are looking for “techy” doctors, nurses and healthcare practitioners to help collect data — the more data in the algorithm, the better the accuracy of results.

“If we can harness the Cloud storage platform to get lots of data, you can run a big Data approach on it and using even really generic data can be very powerful,” Ramchen says.

Weng Chong estimates it will be about 18 to 24 months until the product progresses beyond the first prototype to a commercially available product.
