Saving What You Typed in Firefox or Wordpress Locally To Your Computer

If you’ve noticed, when you are in the midst of writing or composing an email in Gmail or Hotmail, it will automatically help you save it in draft every few minutes. When you’ve finished composing and send the email, the draft will be deleted because a copy has been saved in your Sent folder. This is a great feature because there are many things that can cause the message to be unrecoverable. I have a mouse with 5 buttons and the side ones are for going back and forward. Sometimes the page will just go back by itself and I can lose everything that I typed. Yeah I dropped the mouse a couple of times or probably was too frustrated that I slammed the mouse on the table… But with the autosave to draft, I can always get back mostly what I’ve typed.

When my mouse goes bonkers and makes the browser goes back by itself during me writing a blog post, I am still safe from it because WordPress is bundled with the open source HTML WYSIWYG editor TinyMCE, and if I hit the back button, I will get a warning saying “Are you sure you want to navigte away from this page? The changes you made will be lost if you navigate away from this page. Press OK to continue, or Cancel to stay on the current page.“. Last week I lost about 90% of what I’ve written on Avira and I was really upset about it because I’ve spent the whole day testing and writing about it. Wordpress has a built-in auto save draft feature as well but it didn’t work because so coincidentally the site was having some down time. When I hit the Save Draft button for final saving and the page went blank. Hitting the back button gave me an empty draft! To prevent this from happening again, this is what I’ve implemented.

I have 2 choices, either to use a desktop blog-publishing application
or a Firefox plugin.

I found out that Windows Live Writer has a feature where I can automatically save draft to my local computer. So if the Internet
or the website is down, I will still have a recoverable local copy of the draft on my computer. However this feature is not enabled by default. You will need to go to Tools > Options > Editing > check “Automatically save drafts every X minutes”.

ever lose what you’ve written ever again! Well this is useful only for those that uses blog providers such as Wordpress, Blogger, TypePad, LiveJournal, Movable Type, dasBlog and etc. It won’t work on emails or any other web forms.

[ Download Windows Live Writer ]

Another method would be using a Firefox plugin called Lazarus. It enables you to recover lost forms with a single click. Lazarus securely saves forms as you type, allowing you to safely recover your lost work after server timeouts, network issues, browser crashes, power failures, and all the other things that can go wrong while you’re entering forms, editing content, writing webmail, etc, …

You will of course need a Firefox browser and then install Lazarus plugin. It works right out of the box but then you can configure the extra Options to suit your needs.

Execute any File When Application Crashed or Stopped Running (Useful for SRCDS)

I have been managing a Counter-Strike: Source server for nearly a year and believe me, it is a very sensitive and buggy server to maintain. Buggy in the sense that it crashes nearly everyday especially when you are running intensive mods such as ZombieMod or Garry’s Mod. Moreover there are hundreds of third party plugins for SourceMod and EventScripts which makes it even more unstable because of incompatibility problems. It is not easy and time consuming to debug and find out what is causing the crash. So it is important to be able to auto restart the server when the srcds crashes.

If you are running a CSS server on linux, the server itself already supports auto restarting srcds when crash. However on Windows, you can do it via a batch file. It works but it has its problems in doing that which I’ll explain further.

This is the batch file that you need to run to keep srcds.exe open by automatically running when crashed or closed.

@echo off
cls
echo Protecting srcds from crashes...
echo If you want to close srcds and this script, close t
he srcds window and type Y depending on your language followed by Enter.
title srcds.com Watchdog
:srcds

echo (%time%) srcds started.
start /wait srcds.exe -console -game cstrike +map de_dust +
maxplayers 16
echo (%time%) WARNING: srcds closed or crashed, res
tarting.
goto srcds


The command above will monitor for srcds.exe and immediately auto runs the command line if it’s not running. Well Valve recommends that we should wait for at least 10 seconds before restarting so that there is enough time for the memory to clear up. I’ve used this batch and noticed that there were a few times the server crashes, restart, crashes again and restart. Previously I’ve written an article that contains a couple of free tools that can auto rerun program when closed but this time I needed something different.

I was looking for a free, small, simple and portable tool that can monitor for a specific process and then run a “different” file when it detects a crash. I found Restart on Crash which has been working perfectly ever since I started using it. Restart on Crash is an monitoring tool that will watch the applications that you specify and automatically relaunch any program that hangs or crashes. You can add any number of applications to monitor, enable/disable them individually and edit the command line that will be used to restart an application. Restart on Crash doesn’t require installation and stores all it’s configuration data in a “settings.ini” file in the program’s folder, so it’s portable. It should be compatible with most NT-based Windows versions.

Basically the below image is the settings for the srcds server. It monitors srcds.exe and when it isn’t running, a run.bat file will be executed.

The more interesting part is the run.bat which is executed when the program detected that srcds.exe is not running. Since it is a batch file, I can program it to run multiple commands.

The first command shows that I ping localhost 3 times. This command is being used as a feature to wait for 3 seconds before going to the second command. The second command from the batch file is to execute CleanMem which is a tool to clean process and file cache to recover even more memory and performance. Then again pause for 10 seconds before running srcds.exe with the full command line. This method has been working perfectly for weeks already and I didn’t need any other more advanced crash recovery software such as Firedaemon that cost money.

SMBv2 Nuke Crashes Windows Vista, 7 and Server 2008 with BlueScreen of Death

About 15 years ago during Windows 95 era, there were a lot of “winnukes” which can cause Windows
to blue screen. Microsoft did release patches to fix those bugs but during that time Internet was still very new and not many people know that there are updates to fix those problems. There was no Windows Update to scan what your system needed to update. Then came Windows 98 and most of the winnukes were patched. However I still remembered that a team called X-Coders has came up with IGMP nukes which can also crashes Windows 98.

Finally XP came and it is considered to be one of the most stable Windows that Microsoft ever released! As stable as it is, hackers still able to find flaw in their system. That time there was another nuker called SMBDie which crashes Windows XP computers by sending a specially crafted SMB request.

It definitely worked because I was pretty much “abusing” it with my childish teenager mindset. I didn’t crash just anyone but only to a particular guy who was downloading a lot with Limewire
and hogging the Internet connection until none of the housemates can use the Internet. If I am not wrong, that bug was patched in SP1.

Just when we thought the latest Windows Vista and 7 is safe, Laurent Gaffié discovered an exploit that can cause a remote computer to get a bluescreen of death and released a proof of concept on 9th September. I only got to know about it few days ago because on the day the exploit was released, I was busy packing my bags and getting ready for my honeymoon.

I found 2 compiled version of the exploit and this is how it looks like. This one has an interface for you to enter the victim’s IP address and clicking the OK button will send a specially crafted packet to the remote computer.











The second one is command line application. Just enter the IP address after the program to launch the attack.

I’ve tried to attack my own computer running Windows Vista SP1 and the computer shows a blue screen and auto rebooted. When Windows is booted up, I got a notification window that says “Window has recovered from an unexpected shutdown” with the problem event name “BlueScreen”.

The good news is Windows Firewall is able to block this attack. Thank God that all Windows Firewall
is turned on by default or else a lot of people will get nuked by another wave of SMBDie. Looks like Windows Firewall is not so useless after all… Windows XP and 2000 are NOT affected as they don’t have the SMB2.0 driver. You can also update your Windows to be patched from this exploit. If you take a look at this video, Immunity Inc has made a working exploit of SMBv2 that can run commands on the remote system!

Uninstall Programs Packaged with Windows Installer in Safe Mode

Whenever you install a software in Windows, most of the time it will come with an uninstaller that allows you to safely remove the program from your computer. This is because software nowadays are very complex and requires registering of OCX or DLL files, registry changes, dropping of files in appropriate places and etc. There are many types of installers and one of the popular one is Windows Installer and Kaspersky uses it to pack their software for users to install and uninstall.

If you’ve installed a software and suddenly Windows has stopped working, the logical way is to boot Windows in Safe Mode and then try to uninstall. Safe mode is a troubleshooting option for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. Unfortunately by default you can’t uninstall a software that is packaged with Windows Installer in Safe Mode. If you try to uninstall, you will get the error “The Windows Installer service is not accessible in Safe Mode. Please try again when your computer is not in Safe Mode or you acn use System Restore to return your machine to a previous good state.











There is a Windows Installer (msiserver) service in Services and if you attempt to manually start it in Safe Mode, you should get an error that says “Windows could not start the Windows Installer service on Local Computer. Error 1084: This service cannot be started in Safe Mode.

To start the Windows Installer service in Safe Mode so that you can uninstall programs, all you need to do is add a new MSIServer registry key. Simply follow the step-by-step instructions below:

1. Hit Win+R, type regedit and click OK.

2. Navigate to the following location in registry editor
:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\

3. Right click at Minimal and select New > Key and name it as MSIServer

4. The (Default) data for MSIServer should show (value not set). Double click on (Default) and type Service in the value data. Close the Registry Editor.

5. Again hit Win+R, type services.msc and click OK.

6. Look for Windows Installer on the list, double click on it and click Start.

You can now uninstall programs that is packed using Windows Installer in Safe Mode. Alternatively, you can also do all the steps above by typing two command lines below in command prompt or at the Run window.

REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\MSIServer" /VE /T REG_SZ /F /D "Service"

net start msiserver

As you can see the first command line is pretty long which I don’t think many people are willing to memorize it. Remember, editing the Windows registry is a risky business and you can end up with more problems rather than fixing it if you do it wrongly. Hence, I’d personally prefer to learn how to do it the long way.

Remove Fake Antivirus and Fake Antispyware Automatically

Fake or rogue antivirus has been around for a long time and they are still not giving up trying to cheat computer users. Normally this is how you will “suddenly” have a rogue antivirus or antispyware installed without you even knowing it. You visit a website and you get a warning message that is very convincing and looks like its coming from Windows telling you that you have a virus/spyware. You click on a button and it will auto install. Here comes the worst part, it then downloads viruses to your computer and the rogue antivirus will find the virus. If you want to clean the virus using the fake antivirus which you just downloaded, you’ll have to purchase the software license.

This is ridiculous isn’t it? Your computer is actually free from virus but after being tricked into installing a fake antivirus, your computer now has virus and very likely you’ll be purchasing a license for a fake antivirus. Some of the rogue antivirus are very hard to remove or uninstall. Fortunately we can automate the whole uninstallation process with this simple small portable tool called Remove Fake Antivirus.

It is very easy to use Remove Fake Antivirus. All you need to do is run the program and click the Start button. Currently Remove Fake Antivirus v1.32 is able to remove 27 types of fake antivirus and antimalware.

For testing purposes, I’ve installed Antivirus Pro 2010 on my computer. Then it reports that there are 33 useless and unwanted files on my computer. 21 are critical privacy compromising content, 9 contains medium privacy threats and 3 are junk. At first I thought they were real virus but when I randomly uploaded 3 files to VirusTotal to have it scanned with 41 different antivirus, surprisingly no threats were detected! To remove Antivirus Pro 2010, I ran RemoveFakeAntivirus.exe, waited for a few seconds and after a reboot, Antivirus Pro 2010 has been removed.

Although Antivirus Pro 2010 gave fake reports, but I am pretty sure that there are some fake antivirus that will drop in real trojan/virus/worm on your computer. Be sure to scan your computer with a reputable antivirus such as Kaspersky, Norton, Avira or BitDefender after removing the rogue antivirus with Remove Fake Antivirus. I personally believe the list of supported rogue AVs will most likely continue to grow if Olzen manage to get more samples of the fake antiviruses. Olzen, the author of Remove Fake Antivirus is 26 years old and he’s from Malaysia too!

Athlon II Or Phenom II: Does Your CPU Need L3 Cache?

It makes sense to equip multi-core processors with a dedicated memory utilized jointly by all available cores. In this role, fast third-level cache (L3) can accelerate access to frequently needed data. Cores should not revert to accessing the slower main memory (RAM) whenever possible.

That’s the theory, at least. AMD’s recent launch of the Athlon II X4, which is fundamentally a Phenom II X4 without the L3, implies that the tertiary cache may not always be necessary. We decided to do an apples to apples comparison using both options and find out.


How Cache Works

Before diving deeper into our tests, it’s important to understand some basics. The principle of caches is rather simple. They buffer data as close as possible to the processing core(s) in order to avoid the CPU having to access the data from more distant, slower memory sources. Today’s desktop platform cache hierarchies consist of three cache levels before reaching system memory access. The second and especially the third levels aren’t just for data buffering. Their purpose is also to prevent choking the CPU bus with unnecessary data exchange traffic between cores.

Cache Hit/Miss

The effectiveness of a cache architecture is measured by its hit rate. Data requests that can be answered within a given cache are referred to as hits. If that cache doesn’t contain the sought data and must pass the request on to subsequent memory structures, this is a miss. Obviously, misses are slow. They lead to stalls in the execution pipeline and introduce wait periods. Hits, on the other hand, help sustain maximum performance.

Cache Writes, Exclusivity, Coherency

Replacement policies dictate how room is created in a full cache for new cache entries. Since data written into a cache eventually has to be available in the main memory, systems can either do this at the same time (write-through) or mark overwritten locations as “dirty” (write-back) and execute the write once the data is wiped out of the cache.

Data on several levels of cache can be stored exclusively, meaning that no redundancy exists. You won’t find the same piece of data in two different cache structures. Alternatively, caches can operate in an inclusive manner, with lower levels guaranteed to hold the data found in higher-levels (closer to the processor) of cache. AMD’s Phenom works with an exclusive L3 cache, while Intel follows the inclusive cache strategy. Coherency protocols take care of maintaining data across multiple levels, cores, and even processors.

Cache Capacity

Larger caches can buffer more data, but they also tend to introduce higher latency. Since cache also consumes large amounts of a processor’s transistors, it is important to find a viable balance between transistor cost and die size, power consumption, and performance/latency issues.

Associativity

RAM entries can either be direct-mapped, meaning that there can only be one position in a cache for copies of main memory, or they may be n-way associative, which stands for n possible positions in the cache to store data. Higher associativity (up to fully associative caches) provide the best caching flexibility because existing cache data doesn’t have to be overwritten. In other words, high n-way associativity guarantees higher hit rates, but it introduces more latency, since it takes more time to compare all of those associations for hits. Ultimately, it makes sense to implement many-way associativity for the last cache level because there’s the most capacity available, and searching beyond that would send the processor out to slower system memory.

Here are some examples: The Core i5 and i7 work with 32KB of 8-way associative L1 data cache and 32KB of 4-way associative L1 instruction cache. Clearly, Intel wants instructions to be available quicker while also maximizing hits on the L1 data cache. Its L2 cache is also 8-way set-associative, while Intel’s L3 cache is even smarter, implementing 16-way associativity to maximize cache hits.

However, AMD follows another strategy on the Phenom II X4 with a 2-way set-associative L1 cache, which offers lower latencies. To compensate for possible misses, it features twice the memory capacity: 64KB data and 64KB instruction cache. The L2 cache is 8-way set-associative, like Intel's design, but AMD’s L3 cache works at 48-way set associativity. None of this can be judged without looking at the entire CPU architecture. Naturally, only the benchmarks results really count, but the whole purpose of this technical excursion is to provide a look into the complexity behind multi-level caching.

Microsoft introduces 'Starter' version of Office



Aiming to turn more new PC buyers into Office users, Microsoft has announced plans for several new ways to obtain the software, including an ad-supported "Starter" edition that can come loaded on new PCs.

In a blog posting Thursday, Microsoft said the starter version of Office will have limited features and include only Excel and Word. The starter version will be part of the Office 2010 family, due out next year, and will only be available on new PCs.

"Office Starter 2010 will provide new PC owners with immediate exposure to the Office 2010 experience on new PCs right out of the box," Microsoft said, adding that it can be upgraded to one of several full versions of Office with a new upgrade card to be sold at retail stores.

The product is a replacement for Microsoft Works, which was Microsoft's low-cost option for PC makers that wanted to include basic productivity software. Microsoft had also quietly tinkered with a free, ad-supported version of Works in recent years.

Office Starter, as opposed to Works, will have full file compatibility with Office as well as features like the 'Ribbon' user interface.

"It really is a replacement for Works," Microsoft corporate vice president Takeshi Numoto said in an interview on Thursday. "It is not a mere renaming of Works. It is an Office product."

Microsoft is trying several ideas to better compete with free rivals such as Google Docs. With Office 2010, Microsoft will also offer a free, ad-supported version of Office that runs in a Web browser. That product, which went into a technology preview last month, requires connection to the Internet at all times.

"It's a way for us to reach customers who may have not experienced Office before, (for them) to get a taste of it," Numoto said.

For years now, Microsoft has grappled with new ways of selling Office, which, along with Windows, is one of the company's two main profit engines. Although Office boasts half a million users, there are lots of folks that use pirated copies of the software or don't have Office at all.

Several years back, as part of a ThinkWeek paper seen by CNET News, Microsoft workers recommend that the company scrap Works in favor of an ad-supported product, saying Microsoft only got a couple dollars of revenue per PC when Works was included.

Numoto would not go into financial details for Office Starter, but did say that it is a "royalty-bearing" product for Microsoft, as Works was. In the past, though, PC makers have had an opportunity to earn back money if customers upgrade from a trial version of Office to the full version. Numoto wouldn't detail how that might work with Office Starter.

Microsoft is also trying out a new method for those that already have a PC to try out Office 2010, once it is available. Called "Click to Run," it brings the notion of streaming to software. Instead of waiting for the whole product to download, users can click a button and start using the software as soon as some of the basics are downloaded. The rest of the product then gets downloaded over time.

Microsoft has already seen the Web increase as a means for getting its software. Numoto said that in the last fiscal year some 23 million downloads of the Office trial, nearly double the number from a year earlier.

Still, he said, downloading a big file means a long wait. "We know we could do a lot better to streamline that experience," he said.

An additional benefit of the Click to Run installation is that it is done through application virtualization. That allows the code, even though it is still being run locally, to run side-by-side with an existing version of Office. That would allow, for example, a user to run a trial version of Office 2010, without getting rid of their existing Office installation.

Apple releases iPhone OS 3.1.2

Apple on Thursday released an update for the iPhone operating system, bringing the current version of the OS to 3.1.2.

According to notes accompanying the update, Apple fixed three bugs, which may not seem like a lot, but they are important. Among the changes is a fix for what Apple says is a "sporadic issue," where the iPhone would not wake up from sleep mode.

The update also resolves an issue that could interrupt the cell network until the phone is restarted. A bug that caused a crash during video streaming has been addressed in iPhone OS 3.1.2.

Apple said iPhone OS 3.1.2 is compatible with the iPhone, iPhone 3G, and iPhone 3GS. The update is available by plugging your iPhone into your computer and clicking on the update button in iTunes.

Once finished, your iPhone will restart and immediately alert you to a Carrier Settings update. This is a very small update that will be completed without needing to restart again.

The Google Android party has begun

By : Marguerite Reardon

(CNET)
-- After two years of waiting, Google Android phones are finally hitting the market en masse.

In the past couple of months, nine devices using Google's mobile operating system have been announced, including the Motorola Cliq, which goes on sale in November, and the new Samsung Moment, which was announced Wednesday at the CTIA Fall 2009 trade show in San Diego, California.

The pipeline is full of more Android devices, some of which have been confirmed and some that are still rumored to be in development.

"We are seeing a lot of interest in Android here," Kim Titus, a spokesman for Samsung, said Wednesday at the CTIA trade show, where the company is showing off its two Google Android handsets: the Samsung Moment and the Samsung Behold II.

"I think these devices have an opportunity to become strong cross-over devices appealing both to business customers as well as to consumers and prosumers."

U.S. wireless operators are also jumping on the Google Android bandwagon. So far, T-Mobile USA, the smallest of the four nationwide carriers, has been the only U.S. wireless operator to offer Android devices. Once the Motorola Cliq and the Samsung Bold II launch, T-Mobile will be offering four different Google Android devices on its network.

But T-Mobile won't be the only Android carrier in the U.S. for much longer. Starting next week, Sprint Nextel will introduce its first Android phone, the HTC Hero. And a couple of weeks later on November 1, it will begin selling the newly announced Samsung Moment.

Verizon Wireless, the nation's largest wireless operator, will also be getting two new Google Android phones in the coming weeks. Verizon executives wouldn't provide specifics about the devices, but one of the devices is expected to be from Motorola.

Verizon and Google said Tuesday that they will be working closely to introduce new Google Android phones.

Even AT&T, the second largest wireless provider in the U.S. and the exclusive U.S. carrier for the iPhone, is expected to have a Google Android phone soon. On Wednesday, the Wall Street Journal published a report stating that AT&T will be offer Dell's soon to be announced Google Android phone.

Device makers see Android as their biggest hope to compete against Apple's iPhone and Research in Motion's BlackBerry devices in the smartphone market. Both Apple and RIM develop their own software that is proprietary to their homegrown hardware.

Like the Google Android operating system, Microsoft's Windows Mobile platform can also be used on different hardware. But as Microsoft struggles to keep pace with the rapidly changing mobile market, some device makers, such as Motorola, are gravitating toward Android.

This is not to say that Microsoft is out of the game. In fact, the company just announced Windows Mobile 6.5 this week at CTIA, but experts, such as CNET's own Bonnie Cha, believe the upgrade is incremental with a bigger overhaul of the software not expected until next year.

Meanwhile, momentum is growing for Google Android phones.

Google unveiled its Android open development operating system in the fall of 2007. It took a year before the first Android phone, the HTC G1 sold by T-Mobile, was introduced.

Many industry watchers had expected other handset makers to start announcing their own Android devices in February 2009 at the GSMA World Congress trade show in Barcelona. But the show came and went with few mentions of Android.

Later that spring, people were expecting Android announcements at the CTIA's spring trade show in Las Vegas. But device makers kept mum. In June, T-Mobile USA and HTC introduced the second Android handset into the U.S. market, the MyTouch.

This phone was supposed to be a more refined version of the G1 and was designed to appeal to the mainstream wireless consumer.

Now as Android is about to hit its second birthday, the much anticipated flood of Android device announcements is beginning. Manufacturers, such as Samsung, Motorola, LG and HTC are announcing multiple Google Android devices. Motorola's co-CEO Sanjay Jha said this week that he expects his company to introduce "multiple tens of products" using the Android operating system.

Even phone makers Sony Ericsson and Nokia, which historically have built phones using the Symbian operating system, are rumored to be working on Android handsets. The operating system has even appealed to companies not traditionally in the cell phone business, such as laptop makers Lenovo and Dell and Chinese telecom equipment maker Huawei.

While Google Android may give device makers, such as Samsung and Motorola, a way to compete with the iPhone, it could be difficult for them to differentiate their products.

So far, the Android devices that have been announced look very similar. All of them sport a touch screen that takes much of the face of the phone. Some, like the Motorola Cliq and the Samsung Moment, also have QWERTY keypads that slides out for consumers who like the feel of real keys.

Samsung's Titus said there are subtle differences in the hardware. For example, the Samsung Moment uses a bright OLED screen that makes images sharper and colors more vibrant.

The screen is also designed to be more energy efficient. And the Moment uses much faster processors that most other cell phones. But he conceded that because all the devices use a touch screen that they look very much alike.

"When you have a screen that takes up so much of the landscape, it's not surprising that they look somewhat similar," he said.

Since the Android platform is completely open, the real customization will likely be software based. For example, the Samsung Moment, which will be sold on Sprint's network, comes preloaded with applications and features specific to Sprint's network.

These applications include Sprint's navigation service and applications for NFL and Nascar, two organizations which have special relationships with Sprint.

Motorola has also customized the user interface for its Cliq phone and it has introduced Motoblur, a social-networking-optimized version of the user interface. Motorola executives told developers at its conference this week that it expects some but not all of its new Android phones to come with Motoblur installed.

While handset makers and wireless operators may be tempted to further customize the Android software, doing so is risky since the promise of an operating system such as Android is to provide developers with an easy and open way to develop applications that can be downloaded across multiple devices.

So far developers have already created more than 10,000 applications for Google Android devices. These apps can be accessed through the Google Android Market. Big developers, such as Facebook, have already begun developing Android specific applications. And at its developer conference, Motorola announced a series of new apps available for the new Cliq, including Accuweather, the Barnes & Noble eReader, MySpace, and QuickOffice, the company said.

But as new devices are introduced on different carrier networks, it will be interesting to see if these applications in the Android Market will work across all the different hardware.

If they do, they could drive more Android device development, which could lead to the Android mobile platform actually living up to the hype that was promised nearly two years ago. And if they don't, then Android will likely become just another mobile operating system that further fragments the market.

What's wrong with Windows 7


Reading between the lines of Walt Mossberg's review
It's a given that Windows 7, scheduled for release in two weeks, is an improvement over Vista. But how does it stack up against Apple's (AAPL) Snow Leopard?

The definitive word comes in Thursday's Wall Street Journal and All Things Digital from Walt Mossberg, the diminutive dean of tech journalists and a man who takes his software reviews seriously. After testing Windows 7 for nine months on 11 different machines, he has pronounced it "the best version of Windows Microsoft (MSFT) has produced." (Ring a bell? See UPDATE below.)

"I still give the Mac OS a slight edge," he writes, "because it has a much easier and cheaper upgrade path; more built-in software programs; and far less vulnerability to viruses and other malicious software, which are overwhelmingly built to run on Windows. Now, however, it’s much more of a toss-up between the two rivals.

"Apple will have to scramble now that the gift of a flawed Vista has been replaced with a reliable, elegant version of Windows."

Mossberg has written a positive review; he has plenty of good things to say about Microsoft's latest operating system, and anybody who is seriously interested in buying it should read the whole thing.

But if you want to know what's wrong with Windows 7, we've excerpted the juicy bits below the fold.

In Walt's words:

* On a couple of these machines, glacial start-up and reboot times reminded me of Vista.
* On a couple of others, after upgrading, key features like the display or touchpad didn’t work properly.
* Windows 7 still requires add-on security software that has to be frequently updated.
* It’s tedious and painful to upgrade an existing computer from XP to 7
* The variety of editions in which Windows 7 is offered is confusing.
* Microsoft has stripped Windows 7 of familiar built-in applications, such as email, photo organizing, address book, calendar and video-editing programs. [They can be downloaded free of charge.]
* Windows 7 still isn’t quite as natural at networking as I find the Mac to be, but it’s better than Vista.
* In my tests, [a new feature called HomeGroups] worked, but not consistently, and it required typing in long, arcane passwords.
* The Mac still started and restarted faster than most of the Windows 7 PCs. But the speed gap has narrowed considerably, and one of the Lenovos beat the Mac in restart time.
* In the name of security, Vista put up nagging warnings about a wide variety of tasks, driving people crazy. In Windows 7, you can now set this system so it nags you only when things are happening that you consider really worth the nag.
* The system for upgrading is complicated, but Vista owners can upgrade to the exactly comparable edition of Windows 7 while keeping all files, settings and programs in place.
* Unfortunately, XP owners, the biggest body of Windows users, won’t be able to do that.
* They’ll have to wipe out their hard disks after backing up their files elsewhere, then install Windows 7, then restore their personal files, then re-install all their programs from the original CDs or downloaded installer files.
* Then, they have to install all the patches and upgrades to those programs from over the years.
* Microsoft includes an Easy Transfer wizard to help with this, but it moves only personal files, not programs.
* This painful XP upgrade process is one of the worst things about Windows 7 and will likely drive many XP owners to either stick with what they’ve got or wait and buy a new one.

"Bottom line," writes Mossberg, "Windows 7 is a very good, versatile operating system that should help Microsoft bury the memory of Vista and make PC users happy."

UPDATE: Kudos to reader Jon T. of Cardiff, Wales, for digging up this quote from Mossberg's review of Vista:

"After months of testing Vista on multiple computers, new and old, I believe it is the best version of Windows that Microsoft has produced." — Wall Street Journal, Jan. 18, 2007

"After using pre-release versions of Windows 7 for nine months, and intensively testing the final version for the past month on many different machines, I believe it is the best version of Windows Microsoft has produced." — Wall Street Journal, Oct. 8, 2009

Is the iPhone hurting AT&T's brand?

(CNET) -- The Apple iPhone has boosted AT&T's subscriber numbers, but network problems and a bevy of complaints from frustrated customers are likely hurting the company's reputation.

While a recent survey by the consulting firm CFI Group found that iPhone users are the most loyal smartphone users, with 90 percent saying they'd recommend the device to a friend, half of all iPhone owners surveyed said they would like to jump ship to another provider if given the chance.

And for the first time, AT&T has scored worse than all four major U.S. wireless operators in terms of overall customer satisfaction for smartphones. According to the survey, AT&T scored 69 out of 100 among users, and 73 among non-iPhone owners. Verizon Wireless was the most satisfying carrier with a score or 79 out of 100 among smartphone users.

Even Sprint Nextel, which has struggled to retain customers due to its poor reputation, scored better than AT&T among smartphone users. It got a 74 out of 100 in terms of customer satisfaction.

The figures are among the first to quantify growing dissatisfaction with AT&T's network.

"AT&T has never fared great in customer satisfaction surveys," said Doug Helmreich, program director with CFI Group. "But they've never been last. Now AT&T is coming up last among smartphone users. The iPhone has been a cash cow for AT&T, but that cash comes at a cost in terms of overall satisfaction."

Public relations and brand experts warn that if AT&T doesn't take steps now to correct its image that it could come back to haunt the company in the future. The main issue for customers is that many users, especially those in urban areas, report poor network coverage and service. Problems with AT&T's 3G wireless have been widely reported on blogs, Twitter feeds, and even in published reports from BusinessWeek and The New York Times.

Customers all over the country have complained about dropped calls and the inability to connect to the 3G network. CNET News writer Elinor Mills documented her frustrating experience with her iPhone in a blog post recently. The story hit a nerve among fellow iPhone users, and more than 400 comments were left on the story. Most of the comments corroborated the writer's plight. And the follow-up story on the same issue garnered at least another 300 comments from readers.

AT&T's company line

And yet, AT&T has not admitted any problem with its network. When questioned about potential problems with the AT&T network being overburdened by iPhone users, Mark Siegel, an AT&T spokesman, reiterated the company line: "We have a strong, high-quality mobile broadband network. It is the nation's fastest 3G network, now in 350 major metropolitan areas."

In fairness to AT&T, the company has acknowledged that it is upgrading its network to deal with increased demand from the iPhone. Siegel said the company plans to spend $17 billion to $18 billion on improving its wireless and wireline broadband networks in 2009.

Of course, this is a few billion dollars less than what the company spent in 2008. During that year, AT&T's annual report indicates it spent $20.1 billion on capital expenditures for its wireless and wireline networks. Still, $17 billion is nothing to sneeze at.

Some of these improvements include deploying 850 MHz technology across AT&T's 3G markets to improve in-building coverage, adding nearly 2,000 new cell sites to improve overall coverage, and increasing capacity in thousands of cell sites with more backhaul infrastructure.

"We are the leader in smartphones in the U.S." Siegel said. "We carry more iPhones than any other carrier in the world and handle more wireless data traffic than other U.S. carrier. Because of smartphones like the iPhone, among many others, people have dramatically changed the way they use the wireless network with data usage exploding."

Indeed, Siegel is correct. iPhone users use the mobile Internet more than other mobile subscribers. So even though Verizon may rank high in terms of customer satisfaction, people are not using the network as much or in the same way as heavy iPhone users.

Still, Siegel said the company will look into the survey results from the CFI Group.

"We welcome and value all feedback from our customers," he said. "We view such feedback as an important opportunity to help us continuously improve our products and services. We will certainly look carefully at the CFI Group survey results to see what we can learn from it."

Of churn and confidence

For now, AT&T's potential image problems haven't been hurting the company. In July, it reported that it had reduced its churn rate, or the rate at which customers dump it service, yet again to 1.09 percent for subscribers on a contract. This is one of the lowest churn rates in the industry.

"The surest indication of customer satisfaction is churn," AT&T's Siegel said. "And ours is at record-low levels. Our own internal data suggests that our iPhone customers are very satisfied with AT&T."

But AT&T's confidence may be misleading. Currently, AT&T is the only U.S. wireless operator offering the iPhone. Once the exclusivity deal ends, which many believe will happen within a couple of years, dissatisfied customers may flee from AT&T to another carrier.

"I think it's safe to say that the same percentage of people who switched to AT&T for the iPhone, would likely leave if they believed they could get the same experience on a better network," said Helmreich. "And that could cause huge problems for AT&T since nearly half of its iPhone users switched from another carrier."

Public relations and brand experts such as Rob Adler, vice president at Vantage Communications, a technology public relations firm in San Francisco, say that AT&T must fess up to the reality if it doesn't want customers to punish it in the long run.

Adler, who is an iPhone subscriber living in San Francisco, says there is no question that AT&T's network has been overwhelmed. Like many people living in a city, he experiences frequent dropped calls and a sluggish wireless Internet connection.

Even though AT&T is trying to fix its network, he said that denying there is a problem won't win it any points with frustrated customers.

"AT&T can say that there is nothing wrong with their network all they want," he continued. "But when someone is experiencing dropped calls and no access to the 3G network every day, they take it very personally. And it is very frustrating."

Andrew Gilman, CEO of CommCore Consulting Group, which specializes in helping companies manage their brand image, agrees. He said the first thing AT&T needs to do is correct whatever problem it is experiencing. And then it needs to listen to its customers and prove to those customers that the problems have been resolved.

He said that in today's highly connected online communities, companies that refuse to acknowledge their customers' complaints do so at their own peril.

"Even if the network is perfectly fine, if several people in a social network complains, they have immediate influence over a large group of people," he said. "So even if people aren't experiencing the same problem, the negative comments have planted a seed."

Gilman said that the power of social networks has changed the game for companies who find themselves the target of negative customer sentiment.

"The world has changed over the past couple of years," he said. "A few years ago you might have been able to ignore some customer complaints and get away with it. But not anymore. With social media things spiral out of control very quickly. "

He cited the example of how Johnson & Johnson was forced last year to pull an online advertisement for its over-the-counter pain pill Motrin after it triggered protest on the Internet from consumers who thought an ad that depicted mothers with back pain carrying babies in a sling as being insensitive toward mothers. Angry consumers viewing the ads took to blogs, YouTube and Twitter to call for people to boycott Motrin, arguing the ad trivialized women's pain and the method of carrying babies.

Switchers as "satisfaction saboteurs"

Experts have said that AT&T's image problems likely go beyond its network troubles. Helmreich said that AT&T has invited trouble through its exclusive deal to carry the iPhone. About 40 percent of iPhone users dropped their carrier to get the iPhone. These customers weren't switching carriers because they wanted to be on AT&T's network; they wanted the iPhone.

As a result, Helmreich argues that these customers are more likely to be dissatisfied with AT&T's service. And they are more likely to complain and to share their complaints with friends.

Helmreich points out that people with one of T-Mobile's exclusive Google Android phones or Sprint's Palm Pre are also more likely to be dissatisfied with their service if they switched providers for those phones.

"In effect, switchers can be satisfaction saboteurs if they were not already inclined to choose AT&T," he said.

Adler also points out that AT&T's marketing and public relations strategy for the iPhone also helped create animosity toward the company. He said that from the start, Apple has established itself as the more valuable brand in the relationship with an iPhone customer.

Even though AT&T is making the device more affordable by subsidizing each device by at least $300 to $400 a pop, it doesn't highlight this fact to consumers. But Apple is the company that has designed the device. It sells it for $200. And it also offers the cool applications, which are either free or are relatively low cost.

"iPhone users love Apple," Adler said. "They are loyal to the brand and they love the device and all the great applications. All they associate AT&T with is dropped calls, a hard-to-access 3G network, and high network fees. They even make iPhone users pay extra for SMS. It seems crazy to me that AT&T hasn't done anything to throw customers a bone to say, 'We love you as a customer.'"

Adler said that AT&T's exclusivity deal with Apple is a gift, which AT&T should be taking advantage of to create customer loyalty. He said that AT&T likely has plenty of time to redeem itself, but the company must take steps now.

He suggested it does three things: For one, he said that AT&T must admit its network has problems and then fix those problems. The challenge from a marketing standpoint is convincing its customers that the network has been fixed. And to do that, brand expert Gilman suggests that the company use specific examples.

"Once they fix whatever problems they have, they have to get testimonials to back up those claims," he said. "Maybe they could drive through neighborhoods and show people that calls aren't dropping and that the dead zones don't exist anymore."

The second thing AT&T needs to do is to more overtly market and explain its value to the consumer.

"AT&T needs to be more aggressive in promoting what they offer the customer," he said. "All they do is say they have the fastest 3G network, which everyone who owns an iPhone knows is absolutely not true in the real world. It may be true in a lab, but not on the street."

And the third thing AT&T must do is make goodwill gestures to its loyal iPhone customers. Gilman suggests the company give out coupons or anything that shows how AT&T values its customers. Adler thinks that AT&T needs to offer customers, who are already spending a lot of money on their service, more features and services for free.

But he said that free Wi-Fi at AT&T hot spots is likely not enough of a perk, since it only highlights deficiencies in the 3G network. Instead, he thinks that AT&T could offer free SMS to iPhone users renewing their contracts.

Google Brings New Options to Search

Perhaps not to be outdone by Microsoft’s recent quickened pace of innovation in search, Google is adding new ways to slice and dice search results.

On Thursday, Google introduced more categories to its “search options,” a feature brought out in May that allows users to filter results by time (recent results, past year, past month, past week), type of result (videos, forums, reviews) and other criteria.

The new search options allow users to filter for results Google found in the past hour, and for books, blogs and news. Google also added the ability to emphasize or de-emphasize shopping-related results. And it is also allowing users of its search history feature to see only results they have seen before, giving them a quick way to find a page they have already seen.

Nundu Janakiram, a search product manager at Google, said all the new options were intended to give users a quicker way to get to the information they want. He said that the ability to search for items that have appeared on the Web in the past hour showcases Google’s constant indexing and crawling of the Web. But he said it is different from “real-time search,” a much ballyhooed and somewhat amorphous concept that typically refers to searches of services like Twitter or Facebook, where conversations between users are constantly updated.

Mr. Janakiram said that the ability to de-emphasize shopping sites would be useful for someone who was researching a new product, say a digital camera, and wanted to see product reviews and specifications. The same user may want to emphasize shopping sites when he is ready to buy an item.

Google introduced a string of other new search features in the past week. On Friday, for instance, Google enhanced search snippets for some results, allowing users to jump directly to the information they were looking for inside a Web page. In a search for trans fats, for example, a user might see a Wikipedia entry and links to jump from the snippet directly into sections of the page that discuss the chemistry of trans fats, their presence in certain foods or nutritional guidelines.

On Monday, Google began showing its popular hot trends directly on results pages for some of the most popular search keywords at a given time.

And late Wednesday, Google added links to discussion forum entries to search snippets from sites that have such forums. For instance, a search for “getting from Rome to Florence” will return a result from a travel site, with links to discussion forum entries on that site that touch on the topic.

“This past week of launches demonstrates how Google is enhancing the search experience,” Mr. Janakiram said.

A Google spokesman said the quick rollout of new features was not a response to Microsoft’s Bing but rather a reflection of how Google had always innovated in search and other parts of its business.

M.I.T. Taking Student Blogs to Nth Degree

CAMBRIDGE, Mass. — Cristen Chinea, a senior at M.I.T., made a confession in her blog on the college Web site.

“There’ve been several times when I felt like I didn’t really fit in at M.I.T.,” she wrote. “I nearly fell asleep during a Star Wars marathon. It wasn’t a result of sleep deprivation. I was bored out of my mind.”

Still, in other ways, Ms. Chinea feels right at home at the institute — she loves the anime club, and that her hall has its own wiki Web site and an Internet Relay for real-time messaging. As she wrote on her blog, a hallmate once told her that “M.I.T. is the closest you can get to living in the Internet,” and Ms. Chinea reported, “IT IS SO TRUE. Love. It. So. Much.”

Dozens of colleges — including Amherst, Bates, Carleton, Colby, Vassar, Wellesley and Yale — are embracing student blogs on their Web sites, seeing them as a powerful marketing tool for high school students, who these days are less interested in official messages and statistics than in first-hand narratives and direct interaction with current students.

But so far, none of the blogs match the interactivity and creativity of those of the Massachusetts Institute of Technology, where they are posted prominently on the admissions homepage, along with hundreds of responses from prospective applicants — all unedited.

Not every admissions office has been so ready to welcome uncensored student writing.

“A lot of people in admissions have not been eager for bloggers, mostly based on fears that we can’t control what people are saying,” said Jess Lord, dean of admissions at Haverford College, which posted student bloggers’ accounts of their summer activities this year, and plans to add bloggers this spring to help admitted students hear about campus life. “We’re learning, slowly, that this is how the world works, especially for high school students.”

M.I.T.’s bloggers, who are paid $10 an hour for up to four hours a week, offer thoughts on anything that might interest a prospective student. Some offer advice on the application process and the institute’s intense workload; others write about quirkier topics, like warm apple pie topped with bacon and hot caramel sauce, falling down the stairs or trying to set a world record in the game of Mattress Dominos.

Posting untouched student writing — and comments reacting to that writing — does carry some risks. Boring, sloppily written posts do nothing to burnish an institutional image, college admissions officials say, and there is always the possibility of an inflammatory or wildly negative posting.

Pomona has considered having student bloggers, but so far has felt that the risks outweigh the benefits, said Art Rodriguez, senior associate dean of admissions.

“Blogs can certainly help humanize the process,” Mr. Rodriguez said. “The flip side is that a few anxious high school students may think and worry too much about what someone wrote on their blog, and present themselves in a slightly different way than who they really are. And there’s always the concern about the political ramifications, that bloggers may open up an issue or topic that starts something negative.”

But Mr. Lord of Haverford said prospective students’ interest in the summer bloggers calmed his worries.

“High school students read the blogs, and they come in and say ‘I can’t believe Haverford students get to do such interesting things with their summers,’ ” he said. “There’s no better way for students to learn about a college than from other students.”

Many high school seniors avidly follow student blogs at the colleges they are interested in, and post comments. Luka, one of dozens responding to Ms. Chinea, for example, wrote: “I didn’t know about the anime club. I would have never guessed that people at M.I.T. are interested in anime. Oh well ... +1 on my ‘Why should I go to M.I.T.’ list.”

M.I.T.’s student bloggers said they had read the blogs when they were applying, posted comments and connected with other applicants.

“I was blogging myself, almost every day, when I was in high school, and I read the M.I.T. blogs all the time,” said Jess Kim, a senior blogger. “For me they painted a picture of what life would be like here, and that was part of why I wanted to come.”

Ben Jones, the former director of communications at M.I.T.’s admissions office, began with a single blog by a student five years ago, at the dawn of the Facebook era, and noticed high school students responding right away. “We saw very quickly that prospective students were engaging with each other and building their own community,” said Mr. Jones, who now works at Oberlin College, where he has added blogs to the Web site.

The M.I.T. student bloggers have different majors, ethnicities, residence halls and, particularly, writing styles. Some post weekly or more; others disappear for months. The bloggers are sought out as celebrities during the annual “Meet the Bloggers” session at Campus Preview Weekend.

M.I.T. chooses its bloggers through a contest, in which applicants submit samples of their writing. “The annual blogger selection is like the admissions office’s own running of the bulls,” said Dave McOwen, Mr. Jones’s successor in the admissions office, in his message inviting applications.

This year, 25 freshmen applied for four new spots, and, Mr. McOwen said, it was hard to choose.

“You want people who can communicate and who are going to be involved in different parts of campus life,” he said. “You want them to be positive, but it’s not mandatory.”

And not all posts are positive. Ms. Kim once wrote about how the resident advising system was making it impossible for her to move out of her housing — expressing enough irritation that the housing office requested that the admissions office take her post down. Officials refused, instead having the housing office post a rebuttal of her accusations; eventually, the system was changed.

But most of the blogs are exuberant, lyrical expressions of the joys of M.I.T. life, like last month’s post on returning as a sophomore:

“Something’s changed,” wrote Chris Mills. “Now you know what you’re in for, you know the sleepless nights and frustrations are never far away, but this knowledge can’t seem to remove the exhilarating smile on your face. And it’s in that masochistic moment that you realize who you are. That this is what you’re made for.”

Cisco Buys Norwegian Firm for $3 Billion

SAN FRANCISCO— Cisco Systems continued to show just how serious it was about videoconferencing, announcing late Wednesday night the $3 billion acquisition of Tandberg, a Norwegian video communications company.
Cisco sells companies expensive, room-size videoconferencing systems known as TelePresence systems. Tandberg has similar technology but also sells smaller, cheaper conferencing units. In addition, Tandberg has specialized software for managing videoconferencing systems and for creating connections between systems that rely on different underlying technology.

“It really enables us to build out our portfolio,” said Ned Hooper, a senior vice president at Cisco.

Cisco’s corporate videoconferencing products require the company to outfit a customer’s conference room with several large display screens, networking equipment and even special tables, chairs and wall paint. By contrast, Tandberg has a range of gear, including high-definition video systems, that can sit on desks or be used with personal computers.

The all-cash tender offer has been recommended to Tandberg’s shareholders by that company’s directors and stands as an 11 percent premium over Tandberg’s closing price on Wednesday. Tandberg reported $809 million in revenue last year, and has close to $200 million in cash.

In recent years, Cisco, based in San Jose, Calif., has been one of the technology industry’s most aggressive companies when it comes to acquisitions. It has bought close to 40 companies in the last five years, including the $6.9 billion purchase of the set-top box maker Scientific Atlanta and the $2.9 billion purchase of the Web meeting software maker WebEx. This year, Cisco bought Pure Digital, which makes the popular Flip video camera for consumers, for $590 million.

The acquisitions have suited Cisco’s mission of backing products that generate more Internet traffic, which in turn drives demand for the networking hardware that has long been the core of its business.

The deals have also thrust Cisco into new markets like consumer electronics, business collaboration software and computer servers where the company now finds itself in direct competition with its traditional business partners, like Hewlett-Packard, Microsoft and I.B.M.

During an interview last week, Cisco’s chief executive, John T. Chambers, boasted that the company had managed to move into 30 new markets through acquisitions and its own internal product development.

“We are involved in things that may shock you,” Mr. Chambers said, referring to things like smart-grid technology for municipal power systems and the construction of entertainment and networking systems for sports stadiums.

With $35 billion in cash — the most among technology companies — Cisco appears set to continue with this expansion.

“You will see us move with a lot of acquisitions over the next year,” Mr. Chambers said.

Still, companies like Cisco, Dell and EMC must find ways to match the heft of Hewlett-Packard and I.B.M., which have huge technology services businesses to complement their hardware and software pursuits.

Rather than acquiring a large services company, Cisco will continue to partner with independent players like Accenture and Wipro, Mr. Chambers said.

“I think that is a more scalable, faster-speed and less confrontational model,” he said.

As Cisco moves into new areas, it faces the difficult task of trying to find businesses with profits that can match those gained from its networking hardware. Cisco’s routers and switches produce 65 percent gross profit margins.

Mr. Hooper stressed that Tandberg had gross margins of 66 percent. “It fits squarely into our operating model,” he said.

Tandberg has had most of its success selling videoconferencing systems to large companies in North America and Europe. Cisco plans to use Tandberg’s technology to help it pursue smaller companies and eventually to sell to consumers, Mr. Hooper said.

A number of companies make videoconferencing systems. Like Cisco, H.P. sells large systems aimed at companies that need sophisticated tools for their video meetings, like the ability to display graphics and movies.

Microsoft and I.B.M. have focused on adding PC-based videoconferencing to their collaboration software lines, while start-ups like LifeSize have tried to undercut the larger players on price.

Google invites users to join Wave


Rory Cellan-Jones talks to the developers of Google's 'next-generation' messenger service

Google Wave, which combines e-mail, instant messaging and wiki-style editing will go on public trial today.

The search giant hopes the tool, described as "how e-mail would look if it were invented today", will transform how people communicate online.

It will be open to 100,000 invitees from 1600BST, each of whom can nominate five further people to "join the Wave".

The tool is also open source, meaning third party developers can use the code to build new applications.

The developer behind Wave described it as "a communication and collaboration tool".

"It struck us that e-mail is still the main communication tool on the web, which seemed remarkable given that it is 20-year-old technology," said Lars Rasmussen, who, alongside his brother Jens, was the brains behind Google Maps.

In designing Wave, the brothers took as a starting point the idea of "a conversation sitting in a cloud".

"We found we could build a flexible tool with a surprising amount of functionality," Mr Rasmussen told BBC News.

Such functions includes real-time typing.

This means people can see a comment being written character by character and can formulate their answer to a question before a fellow 'Waver' has even finished asking it.

Mr Rasmussen acknowledges that this feature could be annoying, but thinks it is also a great time-saver.

For those unsure whether they want all their Wave friends to see exactly what they are writing, when they are writing it, the developers are working on a draft mode which will allow the real-time aspect to be switched off .

Unlike traditional instant messenger (IM) conversations continue even once everyone has logged out. This means that those invited to a Wave conversation but not currently online, can read the message strand in full at a later date.

Sharing photos

More radical is the inclusion of wiki-style editing tools.

All messages can be edited at any point by members of the conversation and a Playback facility allows everyone to see exactly who has edited what and at what time.

Google, a famously collaborative firm, now writes all its design documents in Wave.

Wave also makes it very easy to share photos, which can simply be dragged from the desktop onto the Wave platform.

"If you are planning a trip. you can talk about it and plan it in Wave and then share all the photos at the end," said product manager Stephanie Hannon.

Google Wave runs in most browsers, with the notable exception of Microsoft's Internet Explorer (IE). Users of IE will have to download a plug-in, known as Chrome Frame to use the application.

Microsoft does not recommend installing this plug-in, claiming it compromises security.

As IE is still the dominant browser, its incompatibility with Wave could affect take-up of the platform.

Google insists the failure of Wave in IE is not an excuse to promote its own browser, Chrome. It said the developers worked "very hard" at trying to make it work in IE.

Much of the code for Wave is written in HTML 5, the next-generation of web language.

In a nod to social-networking site Facebook, there are already a host of applications for Wave, including Sudoku and Chess.

"We are now trying to persuade someone to build a crossword puzzle," said Mr Rasmussen.

He acknowledges that the success of the platform will depend on how many people are willing to join.

"Without other people adopting Wave it will never take off," he said.

"I have been accused of being pathologically optimistic about it but I can't see why people wouldn't want it," he said.

His enthusiasm seems to be being borne out to a certain degree. Since Wave was announced at a Google developers' conference in May, one million people have registered interested.

Wave will have a full consumer launch early next year.
