Eclectic Nathan Zassman always on lookout for new challenges, new fields to conquer
By MYRON LOVE Aviva Natural Health Solutions on St. James Street is not your typical health food store just as Aviva’s founder, Nathan Zassman, is not your typical entrepreneur.
“What is unique about Aviva is that we take a holistic approach to achieving optimum health through a healthy lifestyle,” Zassman says. “I do a tremendous amount of research in a constant quest for finding solutions to people’s health problems. Many of our products were discovered from research I’ve done working to resolve my own health issues.”
As an example, he cites a brand of footwear from Switzerland, kybun, which was recommended after he tore up some knee ligaments four years ago. Doctors told him he would have to have both knees replaced. He tried the shoes – which claim to repair cartilage and, after ten days, he was walking without pain, after having had to use a walker.
“A physiotherapist who shops here was amazed,” Zassman says. “As a result of my own experience, I can advise people about how properly designed footwear can eliminate knee, hip and back pain.”
At Aviva, Zassman focuses on promoting healthy eating (through food products, healthy food preparation, and dietary supplements) and liquids (as in water filtration systems). A healthy living space requires clean air, for which he recommends air purifiers and humidifiers that can improve any environment. He promotes the importance of getting a good night’s sleep (with organic latex mattresses and coverings that facilitate healing while reducing the time it takes to fall asleep), sitting on active health-promoting chairs, and wearing therapeutic footwear.
One of Aviva’s air purifier brands – Blueair – from Sweden – was recently featured on CBC’s Marketplace – which tremendously boosted Aviva’s sales of the products.“We sold more than 300 units in just two weeks after the Marketplace feature,” he reports, and Aviva continues to sell them in large numbers.“We sell our products worldwide, through our website avivahealth.com.”
Aviva’s eclectic mix of products closely mirrors Zassman’s own lifetime of careers and pursuits. The lifestyle guru began life in Beverly, Massachusetts, which is about 20 miles northeast of Boston. In high school and beyond, he studied trombone and voice at both the prestigious Manhattan School of Music in New York City, and, later, at the American Conservatory of Music in Chicago. He was performing regular concerts in Carnegie Hall with the American Symphony Orchestra when he was only 19 years of age.
In Chicago he performed in the Chicago Civic Orchestra, the training orchestra of the Chicago Symphony, and was a member and soloist with the North Side Symphony of Chicago. Nathan’s first experience as an entrepreneur also occurred in Chicago, when he founded The Zassman Brassmen, a brass quintet that performed educational concerts in schools, as well as formal concert performances.
In 1974, after six of years of study in Chicago with the famous brass pedagogue Arnold Jacobs, Zassman won the audition for second trombone in the Winnipeg Symphony. In addition to his role as a trombonist with the WSO, he joined the faculty of the University of Manitoba, teaching the brass instruments, conducting brass ensembles, and teaching “Brass Techniques” at the Faculty of Education, outlining the basics of all the brass instruments to music education students.
But Zassman has never been defined by just one category. Concurrent with his career in music, he trained as a professional photographer at the Winona School of Professional Photography in Indiana, earning 20 diplomas and Certificates of Merit in a wide range of photographic disciplines. “I became interested in photography while in Chicago,” he recalls, “and spent my summers studying at the best schools and with famous photographers, to refine and improve my craft. I approached photography the same way I did music, seeking out the finest photographers who shared their unique techniques, either privately, or through classes.”
While in Chicago, Zassman developed an interest in Eastern philosophy, studying yoga and astrology at the College of Occult Studies in Chicago. In Winnipeg, he later founded Celestial Interface, producing astrological birth charts for those interested in learning how astrology can improve their lives. He was also appointed CBC Official Photographer, appearing on about a dozen radio and TV spots with CBC Radio and Television, preparing and discussing astrological birth charts on political candidates running for local and national elections.
Zassman founded a photography business specializing in architectural, portrait and commercial photography, creating magazine covers and illustrations for local and national magazines. He also became the Winnipeg Symphony’s official photographer, doing portraits of all the musicians for the symphony programs, as well as taking the annual photo of the orchestra. For many years he taught photography at a school he founded in Winnipeg while the symphony was in session from September to May, and taught professional photographic techniques at the Winona School of Professional Photography, the University of Saskatchewan Department of Art, and the Saskatchewan School of the Arts during the summer months. Zassman also founded The Heliograph Gallery, the first gallery that specialized in photography in Winnipeg.
Now, one would think that teaching photography, performing with the Winnipeg symphony and teaching at the University of Manitoba School of Music would be more than enough to keep someone busy, but Nathan Zassman is a cut above average. He further added businessman to his resumé when he got into computer sales on the ground floor in 1982.
“I had always been interested in cooking and nutrition,” he recalls. “In the early 1980s, I was hired by a local book publisher to write a cookbook with an original idea. I was planning to write the book on my IBM typewriter, but a friend recommended I use a word processor, as he told me that no one used a typewriter anymore for writing.”
One of Nathan’s photography students worked for a local company, Westsun Media. They were selling the Kaypro, which had been rated the best value brand of computer that could be used as a word processor. Nathan purchased a Kaypro with two floppy disk drives for $4000, and couldn’t believe the freedom it provided, allowing him to edit his work, and even check his spelling.
Zassman was so enthused with his computer that he encouraged all his friends to buy one as well. “I was sending so many customers to Westsun to buy a Kaypro computer that I asked the owner, Marc Raymond, if he would allow me trade mine in for a new model with a built in hard drive, which was revolutionary at the time for a portable computer. Marc acknowledged that all his sales were thanks to Nathan and offered him the job as sales manager for the computer division of Westsun. After a short time, Nathan decided he should start his own business and left Westsun.
Thus, in 1982, the musician became a businessman with the founding of Aries Microsystems. “Our business grew rapidly,” Zassman recalls. “By 1986, Aries ranked as the fastest-growing business in Manitoba.” But in 1988 he found that the added responsibilities of running a computer business were interfering with his musical career, so he decided to sell Aries to one of his employees. However, Zassman retained his passion for computers and after his three year non-competition clause from the sale of Aries came to an end, in 1991 he started a second computer company – Opus Computer Solutions.
Zassman retired from the WSO in 1995 to devote himself full time to his new company. “In 1997, I bought the former Winestock’s Wholesale building at 52 Adelaide in the Exchange District and moved my computer business into the downtown marketplace area,” he recalls. “In 2001, I decided to set up a gym on the third level for my computer technicians. I wanted to encourage my technicians to include exercise in their lifestyle. I did my research and bought the best fitness equipment available.”
After a short time, he decided to also sell the fitness lines he purchased for the Opus gym, and Aviva Natural Health Solutions was born.
Zassman then went to the United States, studying Nutritional Therapy in Medical Practice with Jonathan Wright, M.D., and Alan Gaby, M.D., and obtaining certificates in 2003 and 2007. By 2005, Aviva was bringing in enough revenue to stand on its own, so Zassman sold Opus Computer Solutions in 2007 to focus entirely on his new venture.
“I seem to change careers every 20 years or so,” he says.
He moved Aviva to its current location, at 1224 St. James Street, in 2010. And, while still very active in the operations of Aviva, true to form Zassman continues to grow and explore other fields. A bass/baritone, he’s returned to singing and was studying with Mel Braun at the University of Manitoba, as well as singing in two choirs – until Covid forced a pause. On top of all that, a few years ago, began taking acting classes with the Prairie Theatre Exchange. He became a member of Shoestring Players, and has appeared in three plays so far.
He continues to indulge his passion for healthy cooking and baking bread. While running Opus, he became well known for offering his customers and staff free loaves of bread, made from freshly ground organic grain, and is still doing so at Aviva. These days though, he concentrates on sourdough bread. He offers his starter to anyone interested in baking sourdough bread, for free.

Hacker and Fraud Prevention for Online Gambling Profiles
Safeguard your online casino & sports betting accounts from cyber threats
Follow these 10 vital steps to reinforce your online gambling profile by enabling two-factor authentication, using VPNs, unique passwords and more.
With the global online gambling market projected to reach over $100 billion by 2026, securing your online casino and sportsbook accounts is more critical than ever. As digital wallets swell with winnings so too does the motivation for cybercriminals to steal credentials and loot accounts.
#1. Activate Two-Factor Authentication
Topping the list is two-factor authentication (2FA) – requiring two credentials to login instead of one at FanDuel. Often this entails providing your password plus a one-time code sent via SMS or email.
Per an Oracle study, implementing 2FA would have thwarted 99% of historical cyber attacks that involved stolen credentials.
Most regulated online gambling sites offer 2FA, accessible under account settings. Turn it on immediately for stronger defense.
#2. Never Reuse or Recycle Passwords
A cardinal sin is recycling the same password across multiple sites or services. Once one account is breached, cyber thieves can access more accounts using that same password.
To avoid this, every account deserves a unique, strong password. For simplicity, utilize a password manager app to randomly generate and store site-specific passwords.
#3. Install a VPN for Public Wi-Fi Access
When playing online casino games on shared/open wireless networks, your data flows openly and risks interception. That’s where virtual private networks (VPNs) come in.
VPNs encrypt all network traffic to and from your device. This protects your gambling activity and account credentials from Wi-Fi eavesdroppers. VPNs also disguise your IP address.
Some top-rated services include NordVPN, ExpressVPN and CyberGhost.
#4. Keep Software Updated & Run Anti-Virus Scans
You must keep computers and mobile devices updated with the latest OS and security patches. Postponing critical updates leaves open dangerous holes that malware exploits.
Likewise run reputable anti-virus scans to catch viruses attempting to infiltrate systems and spy on login credentials for financial accounts.
#5. Verify the Security & Encryption of Sites
When signing up at online betting sites and casinos, verify the legitimacy of their security measures:
- Confirm the address starts with HTTPS, not HTTP
- Check that data transmissions are encrypted using at least 128-bit SSL
- Ensure site has proper licensing
- Review privacy policy for data storage and sharing
Reputable sites will display trust badges from companies like Norton and TrustE.
#6. Avoid Account Sharing
While tempting to give friends or relatives access to funded accounts, sharing login credentials is extremely risky. You lose control over deposits/withdrawals while exposing yourself to potential theft.
Instead, gift deposits to other player accounts or refer them to open their own secure accounts.
#7. Beware Account Takeover Scams
Exercise caution if contacted unexpectedly about unusual account activity. Savvy scammers will pretend a breach occurred to trick you into handing over your username and password.
If concerned about account integrity, directly access the site yourself and contact customer support – don’t click any links in unsolicited emails.
#8. Monitor Financial Statements
Carefully review online betting account and credit card statements to detect unauthorized transactions right away. Dispute unrecognized activity ASAP to limit losses.
For further vigilance, some banks offer real-time purchase alerts via email or SMS.
#9. Don’t Save Payment Info
Saving credit card or e-wallet details on gambling sites for faster future deposits also expedites withdrawals – by you and potentially hackers.
Instead, manually enter payment info each time to contain potential damage from any account infiltration.
#10. Create a Secure Email
A strong yet oft-overlooked defense is creating a secure email account strictly for gambling transactions. Keep it completely separate from your personal email to isolate threats.
Use a nickname, enable 2FA and establish a strong password using special characters, numbers, case changes and 15+ letters.
Table: Comparison of Top VPNs for Online Gambling Site Security
| VPN Service | Encryption Standard | Number of Server Locations | Allows P2P Traffic | Number of Simultaneous Connections | Money Back Guarantee |
| NordVPN | AES 256-bit | 5400+ | Yes | 6 | 30 days |
| ExpressVPN | AES 256-bit | 3000+ | Yes | 5 | 30 days |
| CyberGhost | AES 256-bit | 7400+ | Yes | 7 | 45 days |
Fortify Your Online Gambling Fortress
As online casinos and sportsbooks explode in popularity, no player is immune to the growing plague of cyber fraud and account theft.
Guard your profile by enabling two-factor authentication, setting strong passwords, installing critical software updates and more. Also research site security measures and payment options.

Vital Role of True Randomness in Modern Computing
The critical need for true randomness in cryptography, simulations, and more
True randomness is essential for encryption, statistical sampling, simulations, and more computing applications to work effectively. We explore why.
The concept of randomness often evokes thoughts of unpredictability and chance occurrences. However in the world of computing, having access to true randomness is vital for many critical applications to function properly. Without the ability to generate random values and data, key aspects of modern technology simply would not work reliably.
In this article, we will explore what constitutes true randomness from a computational perspective, why it is crucially important, and some of the ways that software and hardware attempt to produce randomness reliably. Gaining insight into this topic highlights the dependence much of digital functionality has on the availability of non-deterministic, uniformly distributed random data.
What Makes Randomness “True”?
For data to be considered truly random from an information theory perspective, values must satisfy key mathematical and statistical qualities, for example at Lucky Seven Casino. True randomness implies meeting three core criteria:
- Uniform distribution — All potential values have an equal probability of occurring so that no bias exists towards certain numbers.
- Independence — The value at any position does not relate to or depends on values at other positions. Previous numbers do not influence future ones.
- Unpredictability — Knowing some values provides no useful information to predict other values. Guessing upcoming numbers is mathematically impossible.
Hence, true randomness requires generated data featuring high entropy (information density) with no observable patterns or correlations over any length or time period analyzed. Values must pass various statisticatests of randomness to qualify. True randomness exists only in specific natural phenomena scientists believe exhibit fundamental uncertainty such as radioactive decay. Computational methods can attempt to produce randomness but technically generate only an approximation usually called pseudo-randomness. However for many practical purposes, computationally generated randomness proves sufficient if it passes robust statistical testing.
Why True Randomness Matters Cryptography
Arguably, the area with the most crucial dependence on true randomness is cryptography. All modern encryption technologies require random number generation to ensure security. Encryption systems work by utilizing random numbers for:
- Key generation
- Initialization vectors
- Salts
- Nonces
- Padding
Any bias, predictability or correlation within random values used for the above purposes significantly compromises encryption protocols and introduces vulnerabilities. With trillions of dollars transferred online daily and vast amounts of sensitive data stored digitally, safeguarding cryptography requires high-quality random number generation rooted in solid entropy sources.
Simulations & Modeling
Outside of security, many more computing applications need randomness to operate correctly per their design intent. Monte Carlo simulations extensively utilize randomness to model complex real-world behaviors by running many iterations with differing random inputs. Financial analysis, climate modeling, nuclear reactions and molecular behavior represent common Monte Carlo simulation applications.
Games, Artificial Intelligence & Machine Learning
Gaming, AI and ML commonly incorporate randomness to increase variation, introduce unpredictability, and improve realism. For example, non-player characters in video games use randomness for movement, dialog and behavior to feel more lifelike and less robotic. AI/ML leverage randomness to train networks more thoroughly against a wider possibility space and build more resilient models less prone to biases.
Generating True Randomness via Hardware
Given the pervasive need for genuine randomness across computing, how do software and hardware reliably produce it? Most systems today use either specialized hardware random number generators or hybrid combinations of hardware and software.
Hardware options utilize the inherent randomness within low-level physical phenomena to produce entropy. Different techniques for generating randomness exist but most hardware implementations focus on three main sources:
- Thermal Noise
- Semiconductor Quantum Physics
- Chaotic Oscillator Outputs
| Generator Type | Description |
| Thermal Noise | Amplifies and extracts random electrical noise from resistor thermal vibrations |
| Quantum Physics | Leverages quantum mechanical properties like photon emission timing from LEDs/lasers |
| Chaotic Circuits | Uses unpredictable oscillator circuit outputs from chaos theory |
Semiconductor-based solutions can generate high bitrates up to 5Gbps using compact modern chip fabrication allowing extensive harvestingof entropy. However these sources derive from complex, random physical processes proving impossible to predict or fully model mathematically. This unpredictability provides excellent entropy quality unattainable via software algorithms alone.
Most general-purpose computers now integrate random number generators within CPUs allowing applications access to decent hardware-based random data. For the highest security use cases, dedicated standalone hardware random number generators exist exceeding >100Gbps speeds. Hence accessing genuine randomness is available today even on common computing devices.
Cryptographically Secure Pseudo-Random Number Generators
While hardware mechanisms utilize hard-to-predict physical phenomena to produce randomness, software solutions must take a different approach. Algorithmically-generated randomness cannot achieve true randomness from a physics perspective. However clever mathematical techniques like cyclical algorithms can generate randomness passing many statistical tests of randomness within their output bit length limits.
Cryptographically secure pseudo-random number generators (CSPRNG) serve as the premier software-based method for generating randomness. CSPRNGs work by repeatedly applying cryptographic primitives like hash or cipher functions on initial random seed values. This process produces a chain of output bits not reproducible without the original seed key. Leading CSPRNG algorithms include:
- Hash_DRBG
- HMAC_DRBG
- CTR_DRBG
Software libraries implement these CSPRNGs so developers can integrate quality randomness into applications with proper seeding. Seeding establishes the initial starting point for randomness generation using an entropy source like hardware random number generators or timing variability.
CSPRNGs allow the production of vast quantities of randomized data for any purpose needed. Compared to hardware mechanisms limited by physics on maximum speeds, algorithms scale boundlessly in the bits created as long as adequate computational power exists.
Yet key differences between software and hardware randomness remain. While CSPRNG outputs pass statistical testing and contain no observable patterns, their pseudo-randomness means given the same seed, the exact same value sequence will generate each time. Also, if a CSPRNG algorithm or implementation has flaws, adversaries could predict and exploit output resulting in compromised security. Still, with proper cryptographic design and regular reseeding, CSPRNGs provide quality randomness for most software needs.
Conclusion
From the above exploration, we see true randomness plays a pivotal role across computing – from cybersecurity to simulations and beyond. While no substitutes for true physically-derived entropy exist, modern hardware and hybrid hardware-software solutions provide abundant randomness for practical usage.
However as computing continues evolving with new technologies like quantum, ensuring high-quality randomness generation tackles emerging information security and system reliability challenges. Access to ample true randomness stands necessary now for current computing functionality and lays the foundation for future innovation.
