Track down non-operating system services

When you're troubleshooting a problem in Windows XP, it can be useful to know which services are running. While most of the services running on a Windows XP system relate to the operating system, this is not the case for all of them.

You can use the Services tool, which you can launch via Control Panel's Administrative Tools, to view the running services. But if you use this tool, you must be able to recognize which services relate to the operating system and which do not.

However, there's a little-known feature in the System Configuration Utility that can quickly identify non-operating system services for you.

Follow these steps:


1.. Press [Windows]R to open the Run dialog box.
2.. In the Open text box, type msconfig, and click OK.
3.. When the System Configuration Utility launches, select the Services tab.
4.. At the bottom of the Services tab, select the Hide All Microsoft Services check box.

The System Configuration Utility will then display only non-Microsoft services that are running. Deselect the check box to return to the full list.

iMediaConnection: Bye Bye Email?

Speakers at a recent Blog Business Summit believe blogs are replacing email as an effective two-way dialog tool.

Going forward from the recent Blog Business Summit in Seattle, two powerful messages have been reverberating through the marketing world:

1. Blog feeds are rapidly replacing email as a form of proactive marketing communications
2. Marketers wishing to post their own blogs should not approach the form as another one-way communications medium, but should plan for their blogs to offer two-way dialog.

As to the first point: Spam=bad. RSS=good.

"Email marketing is dead," declares Chris Pirillo, a frequently quoted online marketing and blogging industry consultant based in Canoga Park, Calif. One of the keynote speakers at the Blog Business Summit, Pirillo admits he hasn't always been that skeptical about email as a communications platform. In fact, way back in 1999, Pirillo wrote the best-selling "Poor Richard's E-mail Publishing" guidebook.

So what has changed, and why is blogging often a more effective marketing communications medium than email?

Watching Pirillo speak at the Summit, one got the impression of someone who was a true believer -- but no more. With an animated tone and a hyperbolic stage-pace, Pirillo called out his indictments of email's lost effectiveness.

"Filters are killing 25 percent of legitimate (email) deliveries," Pirillo pointed out. He was referring, of course, to the practice many business users have of setting spam filters so high, that even potentially lucrative emails (such as legitimate inquiries from prospective customers) are grabbed by spam filters and never reach their intended recipients.

As a result of these ramped up spam filters, Pirillo noted that he sees email as an "increasingly polluted channel" in which emails from unknown parties arrive at the server with a filter-ordained, "guilty before proven innocent" presumption. Because of this, "conversion rates are decreasing, blacklists continue to grow, and we have to pay for whitelisting services," he added.

Whitelisting, incidentally, is the practice some corporate email managers have of only allowing mail through from a pre-set list of email addresses. That's a step further than blacklisting, which at least on faith, is supposed to bar the door to obvious spam addresses -- such as, say, the hypothetical getrichquick@franchiseoppsgalore.com.

As Pirillo and others noted, RSS has come to the rescue.

Depending on who you ask, RSS stands either for "Really Simple Syndication," or "Rich Site Summary." At its core, RSS is a small bit of computer code that pushes blog posts from a web server out to the blogosphere, where they can be retrieved almost instantaneously by blog reader web sites and software that users download or sign up for. After signing up or installing blog reader software, users can specify keywords, or even specific blogs, that they are interested in.

Some of these blog reader tools, such as NewsGator and Pluck, can then be set by the user to send out email or pop-up "alerts" when an item that contains a keyword of interest is posted to a subscribed blog. For example, a tourism magazine about Hawaii could receive a blog post from an interactive ad agency about a newly announced restaurant in Maui. If that agency had attempted to send the magazine an email about the new restaurant, it might have been caught in the spam filter.

"RSS is 'push' without the 'proprietary,' Pirillo pointed out. "Right now, it complements email, (but) tomorrow, it will replace news delivery."

Spam, which is the 800-pound gorilla responsible for most enterprise email blacklists and whitelists, is impossible via RSS. "Because the user controls his or her subscription, RSS subscriptions imply confirmation that he or she wants to receive your message," Pirillo added.

While it only takes a minute or two to post a blog message, the most effective blog posts come with a fair amount of forethought and follow-up metrics. Those were key points made by blogging industry consultant Molly Holzschlag at the Summit.

Holzschlag kept reinforcing the point that potential marketing communications bloggers should not be seduced by the medium's ease of authorship, posting and distribution. "Sure, (blogs are) a basic idea, but without a goal, you can fail miserably," she said. "Know very specifically what you want to do with your blog. If you can't put your idea into a few sentences, you probably are trying too hard."

As did others, Holzschlag sounded a familiar refrain: update your blog regularly. Without such feeding and watering, people's attention spans will wander, and they will forget about the blog you have worked to build. "Make sure you really can post regularly. Your blog will die without regular content, period," she added.

To foster potential customer dialog with your blog, Holzschlag recommended comment and Trackback/Pingback features.

Comments, of course, are features that make it possible for readers to offer feedback to your blog posts. With comments, for example, someone reading your blog post could indicate interest or make a suggestion that you might wish to follow up on. That could be the start of a new business relationship.

Most blog authoring tools include comment functionality.

"Comment systems are an extremely powerful means of building community easily," Holzschlag pointed out. Still, her endorsement of comment systems came with a powerful "yes, but" caveat: Make sure you have someone in place that can "moderate" them. As with online discussion list moderators, a blog moderator usually has a password that enables him or her to delete potentially negative or harmful posts from readers.

Trackback mechanisms automatically "ping," or notify, specialized blog indexes and search engines when new items are posted. Technorati, Weblogs.com and Feedster are three of the most prominent of these indexes. Users of these indexes sometimes look for blog posts much in the same way that standard search-engine visitors query for specific search terms.

"Professional web sites should always ping the main services. Most high-end blog software automatically pings several services by default," Holzschlag said.

In most blog comment systems, comments from readers are added to the blog. Because of the scripting that most blogs use, these posts become part of the blogosphere and can be retrieved by blog reader software and blog-specific search engines.

As a result, blogging has become "a new form of one-to-one marketing, but one not always dictated by brand," said Pete Blackshaw, chief marketing and customer satisfaction officer at Cincinnati-based blog marketing consulting and analysis firm Intelliseek, Inc. "It has concentrated more power in (customer) 'influencers,' and thus requires a new targeting mindset."

That perspective ties in with those of others at the Summit, who collectively reinforced the notion that blog posts are not one-way, but rather a two-way means of communication

RedNova News - Can This Black Box See Into the Future?

RedNova News - Can This Black Box See Into the Future?

DEEP in the basement of a dusty university library in Edinburgh lies a small black box, roughly the size of two cigarette packets side by side, that churns out random numbers in an endless stream.

At first glance it is an unremarkable piece of equipment. Encased in metal, it contains at its heart a microchip no more complex than the ones found in modern pocket calculators.

But, according to a growing band of top scientists, this box has quite extraordinary powers. It is, they claim, the 'eye' of a machine that appears capable of peering into the future and predicting major world events.

The machine apparently sensed the September 11 attacks on the World Trade Centre four hours before they happened - but in the fevered mood of conspiracy theories of the time, the claims were swiftly knocked back by sceptics. But last December, it also appeared to forewarn of the Asian tsunami just before the deep sea earthquake that precipitated the epic tragedy.

Now, even the doubters are acknowledging that here is a small box with apparently inexplicable powers.

'It's Earth-shattering stuff,' says Dr Roger Nelson, emeritus researcher at Princeton University in the United States, who is heading the research project behind the 'black box' phenomenon.

'We're very early on in the process of trying to figure out what's going on here. At the moment we're stabbing in the dark.' Dr Nelson's investigations, called the Global Consciousness Project, were originally hosted by Princeton University and are centred on one of the most extraordinary experiments of all time. Its aim is to detect whether all of humanity shares a single subconscious mind that we can all tap into without realising.

And machines like the Edinburgh black box have thrown up a tantalising possibility: that scientists may have unwittingly discovered a way of predicting the future.

Although many would consider the project's aims to be little more than fools' gold, it has still attracted a roster of 75 respected scientists from 41 different nations. Researchers from Princeton - where Einstein spent much of his career - work alongside scientists from universities in Britain, the Netherlands, Switzerland and Germany. The project is also the most rigorous and longest-running investigation ever into the potential powers of the paranormal.

'Very often paranormal phenomena evaporate if you study them for long enough,' says physicist Dick Bierman of the University of Amsterdam. 'But this is not happening with the Global Consciousness Project. The effect is real. The only dispute is about what it means.' The project has its roots in the extraordinary work of Professor Robert Jahn of Princeton University during the late 1970s. He was one of the first modern scientists to take paranormal phenomena seriously. Intrigued by such things as telepathy, telekinesis - the supposed psychic power to move objects without the use of physical force - and extrasensory perception, he was determined to study the phenomena using the most up-to-date technology available.

One of these new technologies was a humble-looking black box known was a Random Event Generator (REG). This used computer technology to generate two numbers - a one and a zero - in a totally random sequence, rather like an electronic coin-flipper.

The pattern of ones and noughts - 'heads' and 'tails' as it were - could then be printed out as a graph. The laws of chance dictate that the generators should churn out equal numbers of ones and zeros - which would be represented by a nearly flat line on the graph. Any deviation from this equal number shows up as a gently rising curve.

During the late 1970s, Prof Jahn decided to investigate whether the power of human thought alone could interfere in some way with the machine's usual readings. He hauled strangers off the street and asked them to concentrate their minds on his number generator. In effect, he was asking them to try to make it flip more heads than tails.

It was a preposterous idea at the time. The results, however, were stunning and have never been satisfactorily explained.

Again and again, entirely ordinary people proved that their minds could influence the machine and produce significant fluctuations on the graph, 'forcing it' to produce unequal numbers of 'heads' or 'tails'.

According to all of the known laws of science, this should not have happened - but it did. And it kept on happening.

Dr Nelson, also working at Princeton University, then extended Prof Jahn's work by taking random number machines to group meditations, which were very popular in America at the time. Again, the results were eyepopping. The groups were collectively able to cause dramatic shifts in the patterns of numbers.

From then on, Dr Nelson was hooked.

Using the internet, he connected up 40 random event generators from all over the world to his laboratory computer in Princeton. These ran constantly, day in day out, generating millions of different pieces of data. Most of the time, the resulting graph on his computer looked more or less like a flat line.

But then on September 6, 1997, something quite extraordinary happened: the graph shot upwards, recording a sudden and massive shift in the number sequence as his machines around the world started reporting huge deviations from the norm. The day was of historic importance for another reason, too.

For it was the same day that an estimated one billion people around the world watched the funeral of Diana, Princess of Wales at Westminster Abbey.

Dr Nelson was convinced that the two events must be related in some way.

Could he have detected a totally new phenomena? Could the concentrated emotional outpouring of millions of people be able to influence the output of his REGs. If so, how?

Dr Nelson was at a loss to explain it.

So, in 1998, he gathered together scientists from all over the world to analyse his findings. They, too, were stumped and resolved to extend and deepen the work of Prof Jahn and Dr Nelson. The Global Consciousness Project was born.

Since then, the project has expanded massively. A total of 65 Eggs (as the generators have been named) in 41 countries have now been recruited to act as the 'eyes' of the project.

And the results have been startling and inexplicable in equal measure.

For during the course of the experiment, the Eggs have 'sensed' a whole series of major world events as they were happening, from the Nato bombing of Yugoslavia to the Kursk submarine tragedy to America's hung election of 2000.

The Eggs also regularly detect huge global celebrations, such as New Year's Eve.

But the project threw up its greatest enigma on September 11, 2001.

As the world stood still and watched the horror of the terrorist attacks unfold across New York, something strange was happening to the Eggs.

Not only had they registered the attacks as they actually happened, but the characteristic shift in the pattern of numbers had begun four hours before the two planes even hit the Twin Towers.

They had, it appeared, detected that an event of historic importance was about to take place before the terrorists had even boarded their fateful flights. The implications, not least for the West's security services who constantly monitor electronic 'chatter', are clearly enormous.

'I knew then that we had a great deal of work ahead of us,' says Dr Nelson.

What could be happening? Was it a freak occurrence, perhaps?

Apparently not. For in the closing weeks of December last year, the machines went wild once more.

Twenty-four hours later, an earthquake deep beneath the Indian Ocean triggered the tsunami which devastated South-East Asia, and claimed the lives of an estimated quarter of a million people.

So could the Global Consciousness Project really be forecasting the future?

Cynics will quite rightly point out that there is always some global event that could be used to 'explain' the times when the Egg machines behaved erratically. After all, our world is full of wars, disasters and terrorist outrages, as well as the occasional global celebration. Are the scientists simply trying too hard to detect patterns in their raw data?

The team behind the project insist not. They claim that by using rigorous scientific techniques and powerful mathematics it is possible to exclude any such random connections.

'We're perfectly willing to discover that we've made mistakes,' says Dr Nelson. 'But we haven't been able to find any, and neither has anyone else.

Our data shows clearly that the chances of getting these results by fluke are one million to one against.

That's hugely significant.' But many remain sceptical.

Professor Chris French, a psychologist and noted sceptic at Goldsmiths College in London, says: 'The Global Consciousness Project has generated some very intriguing results that cannot be readily dismissed. I'm involved in similar work to see if we get the same results. We haven't managed to do so yet but it's only an early experiment. The jury's still out.' Strange as it may seem, though, there's nothing in the laws of physics that precludes the possibility of foreseeing the future.

It is possible - in theory - that time may not just move forwards but backwards, too. And if time ebbs and flows like the tides in the sea, it might just be possible to foretell major world events. We would, in effect, be 'remembering' things that had taken place in our future.

'There's plenty of evidence that time may run backwards,' says Prof Bierman at the University of Amsterdam.

'And if it's possible for it to happen in physics, then it can happen in our minds, too.' In other words, Prof Bierman believes that we are all capable of looking into the future, if only we could tap into the hidden power of our minds. And there is a tantalising body of evidence to support this theory.

Dr John Hartwell, working at the University of Utrecht in the Netherlands, was the first to uncover evidence that people could sense the future. In the mid-1970s he hooked people up to hospital scanning machines so that he could study their brainwave patterns.

He began by showing them a sequence of provocative cartoon drawings.

When the pictures were shown, the machines registered the subject's brainwaves as they reacted strongly to the images before them. This was to be expected.

Far less easy to explain was the fact that in many cases, these dramatic patterns began to register a few seconds before each of the pictures were even flashed up.

It was as though Dr Hartwell's case studies were somehow seeing into the future, and detecting when the next shocking image would be shown next.

It was extraordinary - and seemingly inexplicable.

But it was to be another 15 years before anyone else took Dr Hartwell's work further when Dean Radin, a researcher working in America, connected people up to a machine that measured their skin's resistance to electricity. This is known to fluctuate in tandem with our moods - indeed, it's this principle that underlies many lie detectors.

Radin repeated Dr Hartwell's 'image response' experiments while measuring skin resistance. Again, people began reacting a few seconds before they were shown the provocative pictures. This was clearly impossible, or so he thought, so he kept on repeating the experiments. And he kept getting the same results.

'I didn't believe it either,' says Prof Bierman. 'So I also repeated the experiment myself and got the same results. I was shocked. After this I started to think more deeply about the nature of time.' To make matters even more intriguing, Prof Bierman says that other mainstream labs have now produced similar results but are yet to go public.

'They don't want to be ridiculed so they won't release their findings,' he says. 'So I'm trying to persuade all of them to release their results at the same time. That would at least spread the ridicule a little more thinly!' If Prof Bierman is right, though, then the experiments are no laughing matter.

They might help provide a solid scientific grounding for such strange phenomena as 'deja vu', intuition and a host of other curiosities that we have all experienced from time to time.

They may also open up a far more interesting possibility - that one day we might be able to enhance psychic powers using machines that can 'tune in' to our subconscious mind, machines like the little black box in Edinburgh.

Just as we have built mechanical engines to replace muscle power, could we one day build a device to enhance and interpret our hidden psychic abilities?

Dr Nelson is optimistic - but not for the short term. 'We may be able to predict that a major world event is going to happen. But we won't know exactly what will happen or where it's going to happen,' he says.

'Put it this way - we haven't yet got a machine we could sell to the CIA.'

But for Dr Nelson, talk of such psychic machines - with the potential to detect global catastrophes or terrorist outrages - is of far less importance than the implications of his work in terms of the human race.

For what his experiments appear to demonstrate is that while we may all operate as individuals, we also appear to share something far, far greater - a global consciousness. Some might call it the mind of God.

'We're taught to be individualistic monsters,' he says. 'We're driven by society to separate ourselves from each other. That's not right.

We may be connected together far more intimately than we realise.'

ColorPic by Iconico

If you're starting off a project without much more than a logo or a photo, ColorPic is an absolute gem. Get up close and personal using the handy zoom window, grab the main colors with a snappy CTRL-G, then just pick out the 'bridging' colors from the anti-aliased edges.

Each set of chips is savable as a "palette" so you can easily recall archived project color sets in seconds. All colors are available in RGB and Hex.

Download Colorpic here.


MWSnap by Mirekw.com

MWSnap allows you more easily to target specific areas of the screen, be it a small section of your graphics, a separate menu, a complete window, an entire application view, or your whole desktop. Images can be captured directly to your clipboard and flipped into you favorite image-editing program in seconds. Alternately, you can effortlessly capture dozens of images to a directory simultaneously -- and have filenames auto-generated for each (great for site demos).

That may well be all you ever need from MWSnap, but it also offers a range of useful little widgets, including rulers, programmable hotkeys, dummy cursors (very nice!), color-pickers, crop and rotate tools and info panels.

MWSnap is mighty useful little app provided for your designing pleasure through the good grace of the very talented Mirek Wojtowicz.

Download MWSnap here.


TopStyle Lite from BradSoft

TopStyle is a little CSS editor.

What do you need a separate CSS editor for? Inline auto-complete features in products like Dreamweaver give you all the options you need. Maybe so, but do they let you do any of the following?

* Instantly check property support across a range browsers and specs
* Manage complex sheets easily by expanding and collapsing rules as you work with them
* Construct rules line by line with a powerful style inspector
* Preview changes instantly.

I have to admit, when I started seriously to work with a CSS layout, this little app moved me through the learning curve quicker then anything else I could find. Books, online resources and cheat sheets are all great, but the month I spent absent-mindedly flipping through the Style Inspector panel in TopStyle Lite had me quickly experimenting with CSS I'd never even heard of. It doesn't take long to develop a comfortable familiarity with CSS this way.

All in all, even if you never decide to spend the extra to get the goodies in the Pro version (including most notably 'Split-screen, multi-browser preview', a 'Style Sweeper', validators and 'HTML Tidy' integration), TopStyle Lite will likely serve you very well for years to come.

FireFox and the Web Developer Toolbar


Chris's initial version of the WDT was released in June 2003 and had a killer set of tools for the Web professional, including:

* Convert POSTs to GETs
* Cookie Information
* Current Window Size
* Disable Styles
* Display Form Details
* Enable Autocompletion
* Hide Images
* Outline Block Level Elements
* Outline Images Without Alt Tags
* Outline Table Cells
* Resize to 640x480
* Resize to 800x600
* Resize to 1024x768
* Validate CSS
* Validate HTML
* Validate Section 508 Accessibility
* Validate WAI Accessibility
* View Source

It was impressive. But, just a little over 12 months later, the WDT now has over four times the functionality and it's all killer -- no filler!

There are just far too many features for me to do justice to the current version of WDT in the limited space here. So, here are just a few of my personal faves:

* Edit CSS -- Alter CSS on any site live in the browser as you watch
* Disable JavaScript/CSS/Java without having to wade through the Tools/Options menus
* Generate customized site speed reports with one click
* Display inline dimensions of all images
* Display ID and Class detail (very handy for CSS debugging)
* Outline images without ALT attributes -- pick up your accessibility errors at a glance
* 7 different code validators, plus a facility for you to add your own custom validator (perhaps running on a local network)

Chris has even designed an amazing 1-click 'topographic view', which graphically displays the 'nested-ness' of every element on a page -- the deeper the nesting, the lighter it's tone. Amazing.

Suffice to say that, about once every couple months, one of the SitePoint team members downloads the latest of Chris's babies and we have a collective 'Bill and Ted' moment as we test the new features -- 'Awwwwesome!' (all nodding knowingly).

Accessibility Toolbox from Accessify.com


Feeling a bit guilty about all this accessibility stuff? Me too. My forms and popup code had been perfectly fashionable for years, but all of a sudden people started to roll their eyes at my code, and snigger at me in hallways. Ok, maybe that's the coffee talking, but you know where I'm coming from. You probably want to mend your ways, but you're not sure exactly what the current state of play is.

Enter: Ian Lloyd and his Accessibility Toolbox. Ian has pulled together some of the accumulated wisdom found at his renowned Accessify.com site, and distilled it into this useful little code wizard. At this point, it comprises of an 'accessible form element builder' paired with an 'accessible pop-up builder'. There are buttons reserved for 'accessible tables' and 'accessible forms' but there's no word as to whether these are due any time soon (Ian is happily gallivanting across the globe as we speak, so no breath-holding).


No matter. The two tools provided give you the working code you need in a handful of clicks.

The popup code is designed to take advantage of JavaScript when it's available, without failing miserably when it's not. The code is also clever enough to bring a 'defocused', lost pop-up back to the front position any time the user attempts to re-launch it -- a particularly frustrating failure when it's not adequately accounted for (nod to Creatas.com).

The form element builder is a great way to start moving away from traditional table-layout forms. Using the 'label and input pairs' produced by this little wizard, drizzled liberally with a some tasty CSS , and you'll have low-fat, nutritious and appetizing forms in minutes.
