When an acquaintance called to enquire about the timings of Friday’s annular eclipse of the sun, the longest anyone will witness from Earth this millennium, I was reminded of the another spectacular sky show that took place last year.

While the high point of Friday’s event was a fiery ‘golden bangle’ seen from many parts of the world including the southern tip of India, the solar eclipse of July 22 was all about totality – the complete obscuration of the sun with its ‘corona’ dramatically glowing in a near dark sky.

The moments seem frozen in time.

We were at the Assi Ghat in Benaras.

A sadhu, bathing in the Ganga among thousands of other devout, stood transfixed.

In fact, if a spiritual experience expands human consciousness, helps a person see things in a new light and connects him to a larger reality, then it can be deeply spiritual to watch a celestial spectacle such as an eclipse.

Microsoft on Tuesday announced a refresh of its Surface Pro tablet-laptop computer.Although Microsoft said the fifth generation of the unit has been redesigned from the inside out with more than 800 new custom parts, the Surface Pro looks similar to its predecessor.

"If you were looking for a major redesign of Surface, this isn't it," said Ross Rubin, principal analyst at Reticle Research.Nevertheless, Microsoft has made some significant improvements in the tablet cum laptop.

I mentioned in the recent post about the TCS website hack that it isn’t a great advertisement for a large tech company to put up a third party, (Honeybee Technology Inc. in this case) as its administrative contact on the WHOIS page.

Here is the screenshot of that page on the day of the hacking: Well, it seems that the ‘Administrative Contact’.

Honeybee Technology Inc was a listed Canadian company until trading in its shares was suspended because it was found to be part of a network of companies involved in one of Canada’s largest financial frauds.

In fact one of the main accused in the ‘Mount Real’ scam, Lino Matteo is still listed as the Administrative Contact for the Honeybee Technology Inc website (today’s WHOIS screenshot here) although the site itself seems to be ‘Under Construction.’ Net-net it’s an avoidable embarrassment, to continue being associated with these guys.

Btw, I’m obviously not accusing TCS of any wrongdoing here – a massive company works with tons of vendors and can’t be accountable for all of them.

I mean, what about all the companies who outsourced work to Satyam, (including the Times of India Group)?

The Election Commission’s reported decision to not count any of the paper receipts produced by the voter-verifiable paper audit trail (VVPAT) machines attached to EVMs in the upcoming Gujarat and Himachal Pradesh assembly elections may not pass muster.

Earlier the EC had discussed the possibility of a 5% ceiling on counting VVPAT trails and mandatorily counting paper trails from not less than 5 and not more than 14 polling stations in each constituency.

It silenced those like the Aam Aadmi Party which alleged that EVM tampering had sabotaged its chances in the Punjab assembly elections.

The decision to postpone tallying the paper trail count to EVM count was purportedly necessitated by the need to ensure that the roll-out of 100% VVPAT is a success.

Additionally, there is a lack of clarity on the delays in the counting and result declaration process because of VVPAT counting.

However, candidates who wish to dispute the election outcome can still demand a count of VVPAT machine.However, both grounds are tenuous.

Ultra-expensive computer hardware, a few kilos of dry ice, a massive dewar full of liquid nitrogen (LN2) and some chutzpah to put all this stuff at stake to chase computing records – that is the idea of weekend fun for hardcore computer hardware enthusiasts.

And, last week, I was lucky to be part of this exotic meet as a few of India’s most well-known hardware enthusiasts came together in a small room in south Delhi, aiming to push the latest and greatest computer hardware to its limit in a bid to break onto the world stage of overclocking.Overclocking, or in simpler words, running a computer at a speed higher than what has been specified, gained momentum in 90s when geeks tried to milk every bit of extra performance from expensive computer parts.

After 2000, the price of computer hardware started to creep downwards even as the performance increased by leaps and bounds.

This largely obviated the need for overclocking to save money.

But a large community of hardware enthusiast refused to give up overclocking.

Instead, overclocking, which was earlier a necessity, evolved into a hobby.

It is summer -- a time when a lot of us get to see new movies, many of which totally suck.

The folks who made The Emoji Movie apparently were worried about its Rotten Tomatoes score (it had earned a 0 percent rating at one point, based on a scattering of early reviews), so they stopped critics from publishing further reviews until just before previews began running.

The result was a great opening day, but attendance fell off sharply because, well, the movie sucked.It would seem to me, from an analyst's perspective, that it would be far better to figure out how to make movies that don't suck than to come up with creative ways to get people to see movies they won't like.

The issue is that directors and studios seem to be more focused on deadlines than on quality, but that reminds me of the old bicycle joke: A girl sees her friend walking his bike to school.

She asks why, and he says he is late and doesn't have time to mount the bike.

It was a wonderful piece of engineering: a magnetic tape placed upon a spindle that could store, by the time I became old enough to use one, 1.44MB data.

A hard disk (HD) in computers is the slowest part and even as processors with their many cores gain more and more speed, the computing experience is being held back by storage devices.

Mainstream HDs spin at a pitiful 7200 rhythms per minute (those in laptops fare even worse at 5400) and writing or reading heavy DVDs or CDs is painfully slow.

The result is slow boot time, slow application launch, long load time during gaming, an occasional jerk or two as you access loads of data at the same time or multi-task heavily.

And this on a fairly fast computer; just because storage technology has fallen behind other advances in the field.Till a few years ago, HDs were considered a necessary evil.

Recently, I met Eli Harari, CEO and founder of Sandisk.

Should the management of listed companies unduly worry about financial investors who seek to join the board?

Certainly not, except in the case of rogues who seek to misuse inside information.

They can hold the company to account and demand better performance.

The Companies Act provides the right to any person other than retiring directors to stand for director.

Active shareholder democracy would bring in greater transparency and checks and balances in the system, boosting corporate governance.

Shareholder activism is needed in the Indian context.Banks are now saddled with bad loans, which have surged as many promoters paid off the political system, got loans sanctioned for inflated costs and harvested the excess amounts for themselves.

Typical of any Apple product, iPad is a sleek, shiny gadget with slick interface and, for a change, has been priced somewhat decently.

But it’s not the revolutionary product which we came to expect ever since we heard that Steve Jobs was personally supervising development of “mythical tablet” and was giving it everything he could.Now, don’t get me wrong.

“All of us use laptops and smartphones… is there room for something in the middle.

Better than the laptop, better than the smartphone,” said Jobs on Wednesday as he held an iPad in his hand.

Take the iPhone, stretch it from the sides, add a few snippets from iPod touch, perfect the Kindle idea, throw in a slimmed down iWorks, and there, you have it!

Yet, it lacks support for flash, which is omnipresent on the web and is critical to multimedia content.

I would argue that my warped headline is just about as explanatory as all the reportage and even the WHO study itself.

My understanding of the findings is that while there is no clinching evidence to show a direct link, there is enough to keep scientists interested in conducting more research.

A quick look at headlines from across the world though, is proof that everybody has their own interpretation.

Obviously the mobile companies are thrilled, while (I assume that) folks who make radiation shields will be crying foul!

Granted that scientific research, in particular statistical studies can often be tricky, but this topic was always going to be explosive.

For now though, ignore the nitty-gritties of the number crunching and causation v correlation debate.

In July, the goods and services tax (GST) was rolled out to a mixed reception.

Its objective is to prevent cascading of taxes and avoid built-in taxes — for example, excise duty at the factory gate, duty on equipment used by telecom companies, etc — thereby lowering retail prices and increasing tax revenue by more voluntary compliance.If it proves effective, there is an anticipated increase in GDP by 2%.

But the implementation of GST has not gone down well with everyone as the initial impact on the market has been an increase in the prices of goods and services.

It is also because taxes have become more visible, as compared to earlier when they were hidden and built into the price itself.What was visible earlier was a value-added tax (VAT) imposed by states at the retail level or the service tax imposed by the Centre.

The new 5%, 12%, 18% and 28% tax based on categories divided into essentials, necessities and luxuries has also left the public confused.But if anyone has been particularly hurt by GST, the differently-abled are facing a double blow.

With 5% GST being imposed on disability equipment, the message sent out is not one of inclusion.

HP just took over the PC market lead worldwide.

You probably don't get how incredible this is, so here's an analogy: It's as if a crooked referee put a bunch of lead on a racer who already was overweight and shuffled him to the back of the pack, but in the end, the guy finished first.

You'd seriously want to look under his T-Shirt to see if you'd find Superman's costume.This isn't Apple coming up with an iPod or iPhone and flanking the market -- this is a firm that simply pushed on the gas pedal at a time when everyone said it was going in the wrong direction (PCs were dead, remember?)

-- and kicked everyone's ass.As impressive as that is, there's more.

This is also basically a brand new firm with a new focus, but people still see it with all the baggage the "HP" name brings, including the bad reflection from the massive mismanagement over at its sister company, HPE -- which, in contrast to HP, had all the advantages but couldn't seem to find the gas pedal.

TechCrunch.com had a post up sometime last night claiming that India’s largest software company Tata Consultancy Services’ website, www.tcs.com had been ‘hacked’.

this is a classic DNS hack and only certain name servers seem to be affected.

The WHOIS page for TCS lists the following nameservers:A domain name server is basically a centralized online directory/database which keeps a list of IP addresses corresponding to the domain names that we type into our browser.

When twitter.com recently fell victim to such an attack, the perpetrators could have got access to twitter usernames and passwords if they’d put up a fake login page so that users would think they were entering the information into twitter.com as usual.

Luckily it was just a political statement by Iranian hackers.In this case it seems likely that one (or both) of TCS’ website registrar ie.

Network Solution International’s name servers has been compromised though we’re still awaiting an update from TCS on whether any of theirs were tampered with too.

Then early this month, the news of Dubai-Pune Air India Express flight which plunged dangerously over the Arabian sea broke out and the industry veterans did a spirited recall of ghost flights of the early ’70s.

But then, don’t we all know, that in the aviation industry, anything goes.Now, there have been many incidents/accidents in the past involving diving aircraft — some like AI Express B737 did dramatic descents, while in other cases the descent rate was so gradual that it went unnoticed.

None, however, kept an entire nation riveted like the events that followed the Eastern Airlines December 29, 1972, crash of flight 401.

The aircraft’s autopilot disengaged during a go-around and the jet began a slow descent only to eventually plough into the swamp and crash.

The flight engineer Donald Repo was in the avionics bay to check on a landing gear problem.

The aircrash investigation report said the crew got distracted with the undercarriage problem and failed to monitor flight instruments.It was the first jet air crash in the US history and the sheer magnitude of casualties stunned the nation and its airline industry.

It is one of the 30 major, 135 medium and nearly 3,000 dams planned for full utilisation of the river’s waters, benefiting Madhya Pradesh, Gujarat, Maharashtra and Rajasthan.

The mood was different when the Amazon was tamed, the Aswan was built across the Nile and Bhakra Nangal came up.

The environmental costs of dams were less appreciated and the human cost seen as well worth bearing, for the larger common good.The height of the Sardar Sarovar dam causes heartburn in Madhya Pradesh, where much of the incremental submergence takes place.

Submergence displaces people, mostly poor, sinks cropped land and kills off wild fauna and flora.

Yet, India must build large dams, to harness the monsoons’ bounty that drains away.

The sum total of benefits across space and time from such dams would far outweigh the costs.
