What have we learnt in this week’s experiment? Can we better understand how wearables might be used in workplaces by looking back at history? Just what did FT’s news editor, Alec Russell, make of Sarah’s wearables data? Does he want to roll it out across newsroom? Read more

What could go wrong? Many things, it turns out, when a company wants to use wearables to track its workers or measure its business. Employers have to be aware of potentials for people to game the system, how to ensure cybersecurity and legal compliance, and perhaps most importantly, how not to lose their workers’ trust. Read more

Do employers want to track their staff with wearables, or is it too much information? Would managers even know how to make sense of, and use, the data collected? Read more

How would employees feel about being tracked by their bosses via wearables? Could some grow to value it if it helps them in their work? Read more

Some experts think wearable technology – from sleep monitors to fitness bands – could be the next frontier in how companies monitor their workers, further blurring the lines between our work and private lives.

Over the next four days Sarah O’Connor, the Financial Times’ Employment Correspondent will be fitted out in wearable gadgets while she works, to see if the personal data they generate really would be useful to managers – and whether workers could learn to live with it.

Follow her regular updates via the Wearables at Work Facebook page, where you’ll find her updates, videos, and thoughts on the project. She’ll be tweeting about the project using the #wearables hashtag, and each day, we’ll storify a selection of the Facebook posts and bring it here to the Techblog.

On Monday, the FT began publishing a three-day series about the growing international backlash against US technology companies.

The first part focused on how Silicon Valley has embarked on a charm offensive in the wake of growing concerns about their role in US government surveillance and how they use their customers’ data. Part two highlighted the situation in Germany, which is leading the European regulatory push-back against big US tech groups.

We included a survey with these stories asking readers how they have changed their online habits in the past year due to privacy concerns.

Fashion, just like the tech world, is borne from, reflective of and defined by the cyclical and cultural trends that continually evolve and adapt around it.

Both are businesses that are high-risk and tricky to be in, balancing books around supply and demand. But, more specifically, the real art that defines leaders from the pack is preemptively being able to guess what people want and need before they manage to recognize it for themselves. The best at this are making billions, both in fashion and tech.

But there’s one overlapping sector which both the titans of Silicon Valley and tastemakers of London, New York, Paris and Milan are still struggling to get en vogue.

Wearables.

Just weeks after internet security experts scrambled to patch up vulnerabilities exposed by the Heartbleed bug, a flaw has been found in Microsoft’s Internet Explorer software that is so serious the US department of homeland security is warning people and companies to avoid using the browser.

China invented printing several centuries before Gutenberg’s mechanical press in Germany. Now a Chinese company in Shanghai appears to have stolen a march over Europe in the race to build the world’s first 3D printed house.

A Shanghai company, Shanghai WinSun Decoration Design Engineering Co, says it made 10 3D printed houses (see photos) each costing $4,800 each in less than 24 hours, according to 3ders, a 3D printing industry website.

News that Sina has hired Goldman Sachs and Credit Suisse to help spin off its Twitter-like Weibo service means it is the latest communications tool – after the acquisitions of chat apps WhatsApp and Viber – that investors will be asked put a value on.

Details about the potential New York IPO remain scant, other than that it could value Weibo at more than $5bn. The FT’s Lex has posed some probing questions about the floatation (i.e. Why?) but here are a few more. Read more

This week Indian-born Satya Nadella (pictured) became the third chief executive in the history of the world’s largest software maker, Microsoft.It’s a major win for Nadella. It could be a win for Microsoft.

But apparently, it’s also a win for India.

New Microsoft CEO Satya Nadella has produced an opening memo to employees that is rich in repetitive rhetoric but short on substance. Here is what he really meant.

Forecast that a market is going to grow by a third, investors start to salivate. Tell them it is smartphones and mouths go dry. There was a time when owning Samsung or Apple and shorting BlackBerry or HTC was an easy trade. But things got harder a year or two ago; competition appears to be eroding high-end handset profits.

There’s an interesting note on François-Henri Pinault’s official bio page on the Kering website.Aafter a the usual title/school/professional background stuff, the last line is: “He takes a personal and professional interest in sustainability and the development of e-business.”

It’s the last bit that struck me, given that on Tuesday M Pinault (left, with wife Salma Hayek), through his holding company Artemis became a meaningful investor in Square, the mobile payments company started by Twitter guy Jack Dorsey.

M Pinault was staying mum about the private share purchase, but it makes sense to me on many levels, besides the obvious one above. And I think it may hint at some tantalising possibilities for the future. (Tantalising to speculate on, anyway.)

CES this year has been a sprawling, lively affair with errant film directors on stage, bendy TVs and more drones than you can shake a stick at, but one clear theme has emerged: a lot of tech companies are betting that in the near future, everything will be connected to the internet, all the time.

What might such a future look like? If IBM has its way these ‘connected devices’ – be it pieces of clothing, appliances or cars – would be able to respond in smarter and more natural ways. Then again, your appliance will probably just spend all day trash-talking you. Read more

Enough of lofty keynote speeches and the distant projections of $19tn market opportunities. CES has finally, officially, started – so let’s get to the prototypes and devices in the here and now already. Read more

Monday was all about the big technology companies planting their flags in the areas believed to have a mainstream impact in 2014 – but it was telling that their choices of which segment to claim leadership in was rather varied: Read more

The annual extravaganza for gadget geeks doesn’t officially begin until tomorrow but there is already plenty happening. The FT’s Hannah Kuchler, Tim Bradshaw, Paul Taylor and Matthew Garrahan are in Las Vegas to cover the show, which Hannah says is marked this year by the presence of companies from outside the traditional consumer electronics industry, from healthcare to cars.

But even as technology becomes more integral to products across the board, the market for technology products in 2014 will likely decline, according to forecasts released by the show’s organiser, the Consumer Electronics Association. Read more

Who says the PC is dead? Lenovo’s notebook sales rose 8 per cent year-on-year in the three months to September, a period when global industry shipments fell by 12 per cent.

Fiscal second quarter results on Thursday showed clearly that the Chinese company is not just the world’s biggest PC maker, it is also the only one that has its act together: Acer this week lost its second chief executive in three years, HP still has at least three years to go in its turnaround plan, and Dell has retreated from the public markets to nurse its wounds. Read more

As Twitter’s IPO cranks into action, there is one big question that is puzzling beyondbrics and many others: where are the non-US users based?

In its SEC filing, Twitter admitted that “users outside the US constituted 77 per cent of our average MAUs [monthly active users] in the three months ended June 30, 2013″. Just who are the 77 per cent? And can Twitter make money out of them?
