Old Tray, New Tricks: Windows 7's Taskbar and window
management tweaks are nice. But its changes to the
System Tray - aka the Notification Area - have a huge
positive effect.

Changes in Windows 7 transform the System Tray from
an intrusive eyesore (in Windows Vista) into a useful set of
shortcuts and other controls.
In the past, no feature of Windows packed more
frustration per square inch than the System Tray. It quickly grew
dense with applets that users did not want in the first place, and
many of the uninvited guests employed word balloons and
other intrusive methods to alert users to uninteresting facts at
inopportune moments. At their worst, System Tray applets
behaved like belligerent squatters, and Windows did little to put
users [PARTICLE] in charge.
In Windows 7, applets can't pester you unbidden
because software installers can't dump them into the System
Tray. Instead, applets land in a holding pen that appears only
when you click it, a much-improved version of the overflow area
used in previous incarnations of the Tray. Applets in the pen
can't float word balloons at you unless you permit them to do so.

It's a cinch to drag them into the System Tray or out of it again,
so you enjoy complete control over which applets reside there.
More good news: Windows 7 largely dispenses with the
onslaught of word-balloon warnings from the OS about
troubleshooting issues, potential security problems, and the like.
A new area called Action Center - a revamped version of Vista's
Security Center - queues up such alerts so you can deal with
them at your convenience. Action Center does issue
notifications of its own from the System Tray, but you can shut
these off if you don't want them pestering you.
All of this helps make Windows 7 the least distracting,
least intrusive Microsoft OS in a very long time. It's a giant step
forward from the days when Windows thought nothing of
interrupting your work to inform you that it had detected unused
icons on your desktop.

America’s deadliest building fire for more than a decade struck Oakland, California, on December 2nd 2016, killing 36 people attending a dance party in a warehouse that had become a cluttered artist collective. The disaster highlights an open secret: many cities lack resources to inspect for fire risk all the structures that they should. Even though the Oakland building had no fire sprinklers and at least ten people lived there illegally, no inspector had visited in about 30 years. How might cities make better use of the inspectors they do have?

A handful of American cities have begun to seek help from a new type of analytics software. By crunching diverse data collected by government bodies and utilities, the software works out which buildings are most likely to catch fire and should therefore be inspected first. Plenty of factors play a role. Older, wooden buildings, unsurprisingly, pose more risk, as do those close to past fires and leaks of gas or oil. Poverty also pushes up fire risk, especially if lots of children, who may be attracted to mischief, live nearby. More telling are unpaid taxes, foreclosure proceedings and recorded complaints of mould, rats, crumbling plaster, accumulating rubbish, and domestic fights, all of which hint at property neglect. A building’s fire risk also increases the further it is from its owner’s residence.

Predictive software designed at Harvard that Portland, Oregon, will soon begin using will do that. Perhaps more importantly, the city’s fire chief noticed that buildings marked as being the biggest risks are clustered in areas lacking good schools, public transport, health care and food options. Healthier, happier people start fewer fires, he concluded. He now lobbies officials to reduce Portland’s pockets of deteriorated areas.
