Data Visualization and Digital Economy Compass 2018 Report By Statista

Statista is a very useful portal for Statistics!

It has wealth of information on various domains and presents the statistics and insights in beautiful graphics. Lot of content are paid, but some are free as well.

I had attended an elective course on Data Visualization during my MBA and liked it a lot! I have been following Hans Rosling’s videos on Youtube and the way he narrates stories through statistics and data visualization tools. Here is a glimpse:


I am currently reading a fascinating book “Factfulness” written by Hans Rosling (who unfortunately passed away recently)


I think we must teach such tools and courses in the primary and secondary education. It would help people to cut through the data deluge and extract the meaning.

The reason for this post is for sharing a (free) report published by Statista on “Digital Economy Compass 2018”. It is filled with interesting insights, the one I liked in particular is the following:


All these are loosely categorized as Tech companies but their revenue drivers/business models are so different!

Should the U.S. Air Force Bomb Forest Fires?

I came across an article on this counter-intuitive idea: Should the U.S. Air Force Bomb Forest Fires?

Here is the article:

B-1B Lancer

Earlier this summer, the Swedish Air Force dropped a laser-guided bomb on a forest fire to help suppress the flames. Now there’s a proposal for the United States to do the same, using the might of the U.S. Air Force to fight America’s raging forest fires via bombs and sonic booms. Bombers that have attacked targets in Syria, Afghanistan, and Iraq could instead strike targets in the continental United States—this time saving lives and property.

As the Earth’s climate changes, wildfire season in the western United States has grown from a summertime concern into a year-round struggle. Higher temperatures have meant, according to one government scientist, “severe droughts, meaning more dry fuel, as well as more intense heat waves”. The conditions set the stage for more, larger fires throughout the year. The trend will threaten people, property, and natural spaces, not to mention push the need for government firefighting services to unprecedented levels.

Clearly it’s time for new and crazy-sounding ideas. Last month, the Swedish government, battling wildfires of its own, dropped a GBU-49 laser guided bomb on a remote forest fire. F-15 Strike Eagle Weapon System Officer Mike Benitez, writing in War on the Rocks, proposesusing B-1 bombers stuffed to the gills with bombs to battle wildfires on the American homefront.


The idea here is to snuff out fires the way you’d blow out birthday candles at the base. In Sweden, the shockwave from a single bomb snuffed out flames within a 100-yard radius of the impact point. So, Benitez reasons, why not load up a heavy strategic bomber with up to 84 bombs and do some serious firefighting?

Benitez chose the B-1 for his hypothetical scenario not only because of its bomb-carrying capability, but for the same reason the heavy bomber became a close air support platform of choice in Afghanistan: its long range translated into persistence over the battlefield, enabling the big bomber to hang around above friendly forces and bomb the Taliban for hours. The B-1 could do donuts in the skies over a wildfire as firefighters on the ground work out the best way to tackle it.

The B-1 wouldn’t carry just any bomb, either, but ordinance that was designed for firefighting. Most bombs use a steel casing that fragments into deadly shrapnel, but this would be unnecessary (and dangerous) when fighting fires. A firefighting bomb would use a combustible casing that would disintegrate on impact. Ideally the bomb would use a thermobaric warhead, one that kills via overpressure, as it generates even more powerful blast waves than traditional high-explosive bombs.

The B-1 method is theoretically doable but could be too expensive and dangerous. If that’s the case, then perhaps a big bomber like the B-1, or many smaller jets, could instead fly low and fast over wildfires, using the pressure waves from sonic booms to snuff out fires. As Benitez points out, an aircraft will generate a sonic boom along the length of its flight path at a rate of one mile per thousand feet. This could beat out wildfires over a wide area, and could be repeated as many times as necessary.

Benitez’s firefighting bomb proposal is a bold one and bound to take some flak. The idea of using bombers to do anything but fight a war, especially on American soil, takes some getting used to. Although expensive, the increasing scale and frequency of wildfires in the United States could make them more attractive—especially when firefighting bombers have the potential to reverse a deadly and destructive fire within mere minutes.

I had heard Hindi idiom “लोहा लोहे को काटता है “. This is a real proof of it. This reminds me of a hilarious (and really meaningful) scene from BBC Classic “Yes Minister” in which Sir Humphry says:

It takes time to do things NOW.

The three articles of Civil Service faith:

  • It takes longer to do things quickly;
  • It’s more expensive to do them cheaply
  • And more democratic to do them in secret

Similarly, it takes bombing by Air Force to suppress the flames!
