Nothing thrilled me more the bizarre nature of subatomic
particles in my college school days. Everything about Quantum Mechanics or
Physics was and is still very interesting to me especially the laws and
principles such as the THE DOUBLE SPLIT EXPERIMENT, EINSTEIN’S TIME DILATION,
UNCERTAINTITY PRINCIPLE, SPACE-TIME, ETHER, to mention a few.
I was so in love with these theories, ideas and principles
that I spent 40% of my school time in our school library buried in the many and
sometimes scary nature of our subatomic particles far above the world of ‘Gross
Matter’. To be honest, I missed so much missing classes and I also gained a lot.
When I successfully and single-handedly build the first and the only Periscope
in my school, I was given scholarship and made the Vice president of my school
science club: JUNIOR ENGINEERS AND SCIENTIST CLUB (JETs club) and also doubled
as the physics and chemistry laboratory prefect.
Here I am going to be talking about the UNCERTAINTITY
PRINCIPLE.
Faced with the many and bizarre problems and behavior of the
moving electron in the nucleus of the atom, scientist and physicists in the 19th
century made so many predictions to determine where the electron could be at a
particular time. But all theories, laws and ideas to pin the electron to a fix
position proved futile until Heisenberg
came with his Uncertainty
Principle which for the sake of simplicity states that: the more precisely the position of some particle
is determined, the less precisely its momentum can be known, and vice versa. With
this understanding, scientists’ and engineers were able to develop the first
Nuclear weapon and other breakthroughs in the field of
nuclear physics.
I am still
interested in Quantum physics and who knows I might just be the first African
to develop a Nuclear Weapon since president Buhari recently signed a document
that will see Nigeria and Nigerians going into arms production .LOL

Here Are 5 Common Network Security Mistakes You Might Be Making:
Have you ever been scammed or had a computer virus take over your system. You're left wondering: “how the heck did this happen to me”? You thought you had followed all the standard advice on securing your network and computer, but you still ended up with a security breach or malware infestation.
Here Are 5 Common Network Security Mistakes You Might Be Making:
1. You're Not Using Strong Encryption On Your Wireless Network
Are you scratching your head because hackers broke into your network, even though you had wireless encryption enabled? You may have been using encryption, but you might have been using the outdated and highly vulnerable Wired Equivalent Privacy (WEP) encryption. WEP was cracked years ago and hacking a WEP-encrypted network is now trivial, due to a proliferation of easy to use WEP hacking tools. Even a novice hacker can break into a WEP-based network.
The Solution: replace your network's WEP encryption with Wi-Fi Protected Access 2 (WPA2). WPA2 is a much more robust wireless protection method and is the current standard for “secure” wireless networks. Some older routers may be too old to support an upgrade to WPA2 while others can be upgraded via a firmware update. Check your router manufacturer’s support page for your specific router to see if it supports WPA2.
2. Your Passwords Aren’t Strong Enough
A weak password can be a hackers gateway into your network, your system, and your online accounts. Increased computing power has decreased the amount of time it takes for password cracking tools to crack a password.
You need to make your passwords as long, complex, and random as possible. Avoid use of dictionary words in your password as cracking tools test for these. Having one embedded in your password will help the tool find your password much quicker than if it had random characters in it.
Check out our article on How to Create a Strong Password for tips on composition.
3. Your System Doesn’t Have The Latest Security Patches
Hackers love to find systems with unpatched vulnerabilities because they can be exploited with specially crafted attacks that take advantage of the unpatched weakness. OS vendors are constantly detecting new threats in the wild and developing security patches to close the holes.
Most OSes feature a set-and-forget “auto update” capability that will automatically download and apply the latest security patches on a regular basis.
The Solution: turn on auto update for your OS security patches as well as any apps that have auto update capability. You should also periodically run a manual patch check to ensure that the auto update process isn’t broken.
4. You Don’t Have a Backup Strategy
When things go bad, your first question might be “do I have a backup of those files”? You shouldn’t have to ask yourself this question, you should know the answer, and the answer should be "let me go pull up my backup of those files”.
Backups are critical resources. Some computer malware such as ransomware can encrypt your files and hold them hostage. If you have a backup of your files then you can laugh at the ransom demand and tell those hackers to go stick it in their ear or some other orifice.
Check out our article on Developing a Backup Strategy for some tips on how to go about backing up your stuff.
5. You’re Not Aware of The Latest Threats And Scams
Scammers and hackers are constantly evolving their tools and tactics. Educating yourself on the current threats is key to not falling victim to the newest and most dangerous scams and hacks happening in the world.

QHN, Our big story - Net Neutrality
Quantum Hack Networks-QHN, bring to you the new word in the tech industry and it means and stands for, Net Neutrality, enjoy.
Net neutrality (also network neutrality, Internet neutrality, or net equality) is the principle that Internet service providers and governments should treat all data on the Internet equally, not discriminating or charging differentially by user, content, site, platform, application, type of attached equipment, or mode of communication. The term was coined by Columbia University media law professor Tim Wu in 2003 as an extension of the longstanding concept of a common carrier.[1][2][3][4]
Examples of net neutrality violations include when the Internet service provider Comcast intentionally slowed peer-to-peercommunications.[5] In 2007, one other company was using deep packet inspection to discriminate against peer-to-peer, file transfer protocol, and online games, instituting a cell-phone style billing system of overages, free-to-telecom value-added services, and bundling
Net neutrality[edit]
Network neutrality is the principle that all Internet traffic should be treated equally.[7] According to Columbia Law School professor Tim Wu, the best way to explain network neutrality is as a principle to be used when designing a network: that a public information network will end up being most useful if all content, sites, and platforms are treated equally.[8] A more detailed proposed definition of technical and service network neutrality suggests that service network neutrality is the adherence to the paradigm that operation of a service at a certain layer is not influenced by any data other than the data interpreted at that layer, and in accordance with the protocol specification for that layer.[9]
Open Internet[edit]
The idea of an open Internet is the idea that the full resources of the Internet and means to operate on it are easily accessible to all individuals and companies. This often includes ideas such as net neutrality, open standards, transparency, lack of Internet censorship, and low barriers to entry. The concept of the open Internet is sometimes expressed as an expectation of decentralized technological power, and is seen by some as closely related to open-source software.[10]
Proponents often see net neutrality as an important component of an open Internet, where policies such as equal treatment of data and open web standards allow those on the Internet to easily communicate and conduct business without interference from a third party.[11] A closed Internet refers to the opposite situation, in which established corporations or governments favor certain uses. A closed Internet may have restricted access to necessary web standards, artificially degrade some services, or explicitly filter out content.
Dumb pipe[edit]
Main article: Dumb pipe
The concept of a dumb network made up of dumb pipes has been around since at least the early 1990s. The idea of a dumb network is that the endpoints of a network are generally where the intelligence lies, and that the network itself generally leaves the management and operation of communication to the end users. In 2013 the software company MetroTech Net, Inc. (MTN) coined the term Dumb Wave which is the modern application of the Dumb Pipe concept to the ubiquitous wireless network. If wireless carriers do not provide unique and value added services, they will be relegated to the dumb pipe category where they can't charge a premium or retain customers.

The strange Chinese word and the Internet
The launch of a new word in China is threatening to break the internet, with the character being shared millions of times despite no-one knowing what it means.
The character, known as "duang", has appeared more than 8m times on China's leading social media site Weibo since it emerged a week ago, generating hundreds of thousands of online conversations.
Foreign Policy, the magazine, has now dubbed the character as a "break the internet" viral meme in the same ilk as last year's image of Kim Kardashian and last week's multi-coloured dress.
The new character has connections to film star Jackie Chan. A fake advert featuring Chan, who sponsors numerous products in China, appeared on video streaming site Youku for herbal shampoo Bawang, which Chan endorses. At the end of advert, Chan appears to say of the product: “It’s just … it’s just … duang!”
USA and UK hack consumer sim cards
US and British intelligence agencies hacked into a major
manufacturer of Sim cards in order to steal codes that facilitate eavesdropping
on mobiles, a US news website says.
The Intercept says the revelations came from US intelligence
contractor turned whistleblower Edward Snowden.
The Dutch company allegedly targeted - Gemalto - says it is
taking the allegations "very seriously".
It operates in 85 countries and has more than 40
manufacturing facilities.
The Intercept says that "the great Sim heist" gave
US and British surveillance agencies "the potential to secretly monitor a
large portion of the world's cellular communications, including both voice and
data".
It says that among the clients of the Netherlands-based
company are AT&T, T-Mobile, Verizon, Sprint and "some 450 wireless
network providers around the world".
Full investigation
The Intercept alleges that the hack organised by Britain's
GCHQ and the US National Security Agency (NSA) began in 2010, and was organised
by operatives in the "Mobile Handset Exploitation Team". Neither
agency has commented directly on the allegations.
However GCHQ reiterated that all its activities were
"carried out in accordance with a strict legal and policy framework which
ensures that our activities are authorised, necessary and proportionate".

Here comes the terabyte phone
A big selling point of smartphones is their ability to hold much of your data -- photos, videos, your entire music library -- on a little device.
But over the years, their storage capabilities, usually no more than 64 GB, haven't kept pace with all the movies, games, apps and other memory-hogging minutiae of modern digital life.
Many people keep stuff in the cloud, but that requires Wi-Fi access.
It's frustrating to have to delete music or videos every time you want to store something new on your phone. But thanks to some advances in memory design and construction, we may be about to expand our devices in a big way.
"Because it's this amazing material, the industry understands it," Tour said, noting that the key to the scalability of the design is industrial availability. Indeed, Rice's RRAM can be manufactured at room temperature and relatively lower voltages compared with other versions.
RRAM is the next step for an industry that's finding the limits to flash memory. Like flash, RRAM doesn't need continuous power. But it's also much faster, since it can be built into more versatile arrays and stacked into bigger pieces.
"You've got to get into the third dimension to pack up enough density in the memory" in order to keep the capabilities growing, Tour said. Flash memory has kept up with Moore's Law -- the ever-increasing power of microchips -- by giving more functionality to the devices on the chips, he says.
But RRAM does a better and more efficient job.
"It's this insatiable desire for memory that's driving all this," he said.
Tour's team is one of many working on the problem, though he believes his approach has an edge because of its use of silicon oxide instead of more exotic materials. Licensing is under way, he says, and prototypes will be further test the concept's viability.
But if everything pans out, phones with a terabyte of memory -- that's 1,000 GB, enough to hold hundreds of feature-length movies -- are just the beginning, Tour says.
"Because silicon oxide is glass and it's transparent, we've built these on glass, we've built this on top of plastic, so it can even be part of the coating you're looking at through the screen," he said.
Tour believes it'll be a world like that portrayed in the movie "Minority Report," with flexible, rollable digital "newspapers" and writable smart windows.
Talk about expandable.
