Rules for Radicals

  1. “Power is not only what you have but what the enemy thinks you have.”
  2. “Never go outside the expertise of your people.”
  3. “Whenever possible go outside the expertise of the enemy.”
  4. “Make the enemy live up to its own book of rules.”
  5. “Ridicule is man’s most potent weapon.”
  6. “A good tactic is one your people enjoy.”
  7. “A tactic that drags on too long becomes a drag.”
  8. “Keep the pressure on.”
  9. “The threat is usually more terrifying than the thing itself.”
  10. “The major premise for tactics is the development of operations that will maintain a constant pressure upon the opposition.”
  11. “If you push a negative hard and deep enough it will break through into its counterside.”
  12. “The price of a successful attack is a constructive alternative.”
  13. “Pick the target, freeze it, personalize it, and polarize it.”

blockchains benefits over client-server model in IOT

Decentralized blockchains offer further benefits over the current client-server model used in IoT. Their decentralized architecture means that identity can be protected and guaranteed. Currently, IoT devices identify themselves via cloud servers, with their identification data held in these databases. As such, the data can be compromised, stolen or imitated, presenting a major security threat to any application that runs atop such a network.

By using a decentralized blockchain, we can protect these identities through the use of asymmetric cryptography and secure hashing algorithms. Devices would be registered according to their own corresponding blockchain addresses, guaranteeing their identity. This blockchain layer can provide a level of security and frictionless identification unmatched by the existing centralized infrastructure.

Henry Ford on Labour Unions

Ford was adamantly against labor unions. He explained his views on unions in Chapter 18 of My Life and Work.[33] He thought they were too heavily influenced by some leaders who, despite their ostensible good motives, would end up doing more harm than good for workers. Most wanted to restrict productivity as a means to foster employment, but Ford saw this as self-defeating because, in his view, productivity was necessary for any economic prosperity to exist.

 

He believed that productivity gains that obviated certain jobs would nevertheless stimulate the larger economy and thus grow new jobs elsewhere, whether within the same corporation or in others. Ford also believed that union leaders had a perverse incentive to foment perpetual socio-economic crisis as a way to maintain their own power. Meanwhile, he believed that smart managers had an incentive to do right by their workers, because doing so would maximize their own profits. Ford did acknowledge, however, that many managers were basically too bad at managing to understand this fact. But Ford believed that eventually, if good managers such as he could fend off the attacks of misguided people from both left and right (i.e., both socialists and bad-manager reactionaries), the good managers would create a socio-economic system wherein neither bad management nor bad unions could find enough support to continue existing.

Mobile messaging revenue worldwide by carrier standard from 2015 to 2021 (in billion U.S.D)

NOTE:

Rich Communication Services (RCS) is a communication protocol between mobile-telephone carriers and between phone and carrier, aiming at replacing SMS messages with a text-message system that is richer, provides phonebook polling (for service discovery), and transmit in-call multimedia.

SMS (short message service) is a text messaging service component of most telephone, internet, and mobile-device systems.[1] It uses standardized communication protocols to enable mobile devices to exchange short text messages. An intermediary service can facilitate a text-to-voice conversion to be sent to landlines.
SMS was the most widely used data application, with an estimated 3.5 billion active users, or about 80% of all mobile subscribers, at the end of 2010.

core dynamics of imperial decline

In his seminal essay The Fate of Empires, Sir John Glubb listed these core dynamics of imperial decline:

(a) A growing love of money as an end in itself.

(b) A lengthy period of wealth and ease, which makes people complacent. They lose their edge; they forget the traits (confidence, energy, hard work) that built their civilization.

(c) Selfishness and self-absorption.

(d) Loss of any sense of duty to the common good.

Glubb included the following in his list of the characteristics of decadence:

— An increase in frivolity, hedonism, materialism and the worship of unproductive celebrity.

— A loss of social cohesion.

— The willingness of an increasing number to live at the expense of a bloated bureaucratic state.

8 technologies the Pentagon is pursuing to create supersoldiers

1. Bulletproof clothes made of carbon chainmail

Researchers tested the potential ballistic protection of graphene by firing tiny bullets of gold at it. They found that the material was stronger, more flexible, and lighter than both the ballistic plates and the Kevlar vests troops wear. And, a million layers of the stuff would be only 1 millimeter thick.

MIT’s Institute for Soldier Nanotechnologies is working on an effective manufacturing method for graphene-based chainmail, potentially giving troops better protection from a T-shirt than they currently get from bulky vests.

2. Synthetic blood

Synthetic blood would be much more efficient than natural cells. The most promising technology being investigated is a respirocyte, a theoretical red blood cell made from diamonds that could contain gasses at pressures of nearly 15,000 psi and exchange carbon dioxide and oxygen the same way real blood cells do.

Super soldiers with respirocytes mixed with their natural blood would essentially have trillions of miniature air tanks inside their body, meaning they would never run out of breath and could spend hours underwater without other equipment.

3. Seven-foot leaps and a 25 mph spring

Scientists at MIT and other research universities are looking for ways to augment the human ankle and Achilles tendon with bionic boots that mimic kangaroo tendons. Humans equipped with such boots would be able to leap seven feet or more, sprint at inhuman speeds, and run all day without wearing out their muscles.

4. Pain immunizations

DARPA’s Persistence in Combat initiative aims to help soldiers bounce back almost immediately from wounds. Pain immunizations would work for 30 days and eliminate the inflammation that causes lasting agony after an injury. So, soldiers could feel the initial burst of anguish from a bullet strike, but the pain would fade in seconds. The soldiers could treat themselves and keep fighting until medically evacuated.

5. Freedom from sleep

Not all animals sleep the same way. DARPA wants to find a way to let humans sleep with only half of their brain at a time like whales and dolphins or possibly even skip sleep for long periods of time like ENU mice, a genetically-engineered species of mouse, do.

6. Telepathy

Not all brain implants look very comfortable.US Patent Application Richard A. Normann

Part of DARPA’s “Brain Machine Interface” project is the development of better computer chips that can directly connect to a human brain via implants. In addition to allowing soldiers to control robotics with thought alone, this would allow squads to communicate via telepathy.

While the chips are already improving, the project has some detractors. One offshoot of the research is the ability to remote control mice via implanted chips, and some defense scientists worry about the risk of troops having their minds hacked.

7. Powered underwear

While the Harvard researchers working on it prefer the term “soft exoskeleton,” the DARPA-funded robotic suit is essentially a series of fabric muscles worn under the clothes that assist the wearer in each step or movement. This reduces fatigue and increases strength without requiring the huge amounts of power that bulkier, rigid exoskeletons need.

8. Gecko-like climbing gloves and shoes

Geckos use tiny hairs on their feet to grab onto surfaces on the molecular level. While the “Z-Man” project wouldn’t necessarily give humans the ability to crawl along a ceiling like a gecko, special climbing gloves and shoes would allow soldiers to easily climb sheer rock faces or up skyscrapers without any other equipment, drastically easing an assault on the high ground.

java split function not working with a “(” character

The documentation on split() says:

Splits this string around matches of the given regular expression.

(Emphasis mine.)

A dot is a special character in regular expression syntax. Use Pattern.quote() on the parameter to split() if you want the split to be on a literal string pattern:

String[] words = temp.split(Pattern.quote(“.”));

What is a Private Blockchain?

“A private blockchain network requires an invitation and must be validated by either the network starter or by a set of rules put in place by the network starter. Businesses who set up a private blockchain, will generally set up a permissioned network. This places restrictions on who is allowed to participate in the network, and only in certain transactions. Participants need to obtain an invitation or permission to join. The access control mechanism could vary: existing participants could decide future entrants; a regulatory authority could issue licenses for participation; or a consortium could make the decisions instead. Once an entity has joined the network, it will play a role in maintaining the blockchain in a decentralized manner”
