Hello world.
My name is Professor David J. Malan,
I teach computer science at Harvard,
and I’m here today to answer your questions from Twitter.

First up from tadproletarian,
How do search engines work so fast?
Well, the short answer really is distributed computing,
which is to say that Google and Bing,
and other such search engines,
they don’t just have one server
and they don’t even have just one really big server,
rather they have hundreds, thousands,
probably hundreds of thousands or more servers nowadays
around the world.
And so when you and I go in and to Google or Bing

Global spending on information technology is forecast to increase by about 5 per cent to $4.6 trillion next year as businesses accelerate the pace of digital transformation to offset the effects of the pandemic and economic uncertainty, according to Gartner.
Covid-induced market disruptions and widespread adoption of hybrid work models have fast-tracked the process.
“Economic turbulence will change the context for technology investments, increasing spending in some areas and accelerating declines in others,” said John-David Lovelock, research vice president and distinguished analyst at Gartner.
Amid the increasing digital transformation budgets and emergence of latest innovations, The National looks at the 12 top technology trends for the year ahead.
Globally, the Covid-19 pandemic spurred the adoption of digital payments, particularly contactless payments, because of heightened awareness about the spread of infection through banknotes and plastic money.
Increasing focus on cloud computing, network security, big data and cloud storage is expected to boost the performance of the Zacks Computer – Networking industry participants. Accelerated deployment of 5G is driving the proliferation of the Internet of Things (IoT), Advanced Driver Assistance Systems (ADAS), Augmented Reality/Virtual Reality (AR/VR) devices and 5G smartphones, calling for solid networking infrastructure. This has boosted the demand for networking products, favoring the prospects of prominent industry players like Cisco CSCO, Extreme Networks EXTR and Digi International DGII. However, negative impacts stemming from the lingering supply chain disruptions and component shortages are likely to remain a concern in the near term. The spike in inflation and weakness prevailing over global economic conditions and rising crude prices likely to act as additional headwinds.

Increasing focus on cloud computing, network security, big data and cloud storage is expected to boost the performance of the Zacks Computer – Networking industry participants. Accelerated deployment of 5G is driving the proliferation of the Internet of Things (IoT), Advanced Driver Assistance Systems (ADAS), Augmented Reality/Virtual Reality (AR/VR) devices as well as 5G smartphones, which calls for solid networking infrastructure. This has boosted the demand for networking products, which favors the prospects of prominent industry players like Cisco CSCO, Infinera Corporation INFN and Intrusion INTZ. However, negative impacts stemming from the pandemic-triggered supply chain disruptions and component shortages are a concern in the near term. The emergence of the more transmissible variants and a spike in infection rates across many parts of the world (like Shanghai and Hong Kong), resulting in lockdowns, might further affect supply chain issues, which does not augur well for the industry.
