“The Real Zalman” – Life of the man who was undoubtedly the most controversial rabbi ever to live in Winnipeg examined in new book
Reviewed by BERNIE BELLAN On December 12, 2016 the Jewish Heritage Centre hosted an evening at the Asper Campus that was billed as “Rabbi Zalman Schachter and the Winnipeg origins of the Jewish Renewal Movement”.
I wrote about that meeting for this paper and my article about it can be found here: https://jewishpostandnews.ca/features/the-late-rabbi-zalman-schachters-time-in-winnipeg-recalled-at-lively-evening-hosted-by-jewish-heritage-centre/
During the course of that winter evening, various speakers, including his protegé, Rabbi Alan Green, spoke of the great impact Rabbi Schachter had on their lives. Yet, there was also a dissonant note, as several members in the audience were more disparaging in their recollections of Rabbi Schachter.
One theme that was raised throughout that evening, however, was the dearth of written information about Rabbi Schachter’s relatively lengthy stay in Winnipeg (from 1956-1975). I say “lengthy” because, after reading a just-published book about Rabbi Schachter, titled “The Real Zalman,” by Rabbi Chaim Dalfin, looking at the timeline that Rabbi Dalfin produced about Rabbi Schachter’s life makes you realize just how peripatetic he was.
But it’s not all the moves in Rabbi Schachter’s life that make him such a fascinating figure. No, it was his combination of scholarship, charisma – and undoubtedly controversy, that arguably make him the most fascinating rabbi ever to have set foot in this city.
However Rabbi Dalfin hasn’t written a typical biography. Certainly there is a great deal of information about Rabbi Schachter’s life, given in chronological order through the first five chapters of the book. But the final – and lengthiest chapter, deals with an interview that Rabbi Schachter (who by then had added the name “Shalomi” to his surname) gave to Rabbi Dalfin in his Boulder, Colorado home, in 2010, four years before Rabbi Schachter’s death.
You don’t have to be at all conversant with Chasidic Judaism, of which Rabbi Schachter was a follower for most of his life, until he broke away from the Lubavitcher movement in 1968 to found what became the “Jewish Renewal Movement,” in order to find this book quite interesting.
Here’s what Prof. Jonathan Sarna, Professor of Jewish History at Brandeis University, has to say about “The Real Zalman”: “A valuable contribution to the biography and understanding of “Reb Zalman”: founder of the Jewish Renewal Movement, disciple of Chabad-Lubavitch, and a controversial and pioneering rabbinic leader. Wonderful primary sources, including photographs, newspaper articles, and revealing interviews with Rabbi Zalman Schachter-Shalomi makes this a volume that anyone interested in post-war-American Judaism will want to consult.”
Who is Rabbi Chaim Dalfin? After speaking with him several times, I was impressed by how little bias he showed in talking about Rabbi Schachter, either pro or con, and how engaging he was. According to information provided by Rabbi Dalfin, he “has authored over 90 books, is a Chasidic Historian and Ethnographer. He also lectures on psychology and Judaism based on his book, ‘Tanya on Mental Health.’ His books have been endorsed by academic scholars and professors. He lives with his family in New York.”
Rabbi Dalfin’s interest – and it comes through clearly in the book, was to delve into the complex character of an individual who was very hard to pin down, without passing judgment about him to any great extent. (Rabbi Dalfin does explain though why the Lubavitcher movement finally tired of Rabbi Schachter, offering a clear explanation how what Schachter did deviated so thoroughly from Lubavitcher teachings.)
Of all the many aspects of Rabbi Schachter’s life, certainly the most controversial ones have to do with what was not only his open drug use (certainly his experimentation with LSD, taken together with the leading advocate for LSD, Timothy Leary, still comes as a shock to many who don’t tend to think of rabbis advocating using LSD), also his several marriages (four altogether), made him an easy target for criticism.
But Rabbi Dalfin is quite open-minded when it comes to trying to understand what might have motivated Rabbi Schachter to chart such an atypical path for someone who, after all, had been raised devoutly orthodox within the Lubavitcher community. The book offers both criticisms, as voiced by others, of Rabbi Schachter’s often erratic behavior, yet it also offers explanations for those same behaviors.
Winnipeggers especially might find the excerpts that deal with Rabbi Schachter’s 19 year sojourn here especially interesting.
There are many anecdotes, as told to Rabbi Dalfin through the course of the numerous interviews he conducted with a very large number of people who had got to know Rabbi Schachter here. Here, for instance, is an anecdote as told to Rabbi Dalfin by Joe Wilder, who was referred to as “Yossele Wilder” by Rabbi Schachter:
“In 1956, Yossele Wilder was the president of the Hillel House in Winnipeg. He greeted Zalman when he arrived the first time to check out the Hillel House. (Ed. Note: Rabbi Schachter’s first position when he moved to Winnipeg was director of Hillel.)
“After spending a half hour showing Zalman everything in the building, he noticed Zalman wearing a ring. It seemed strange because Zalman looked like a Chassidic rabbi, with his full beard. Wilder knew that Chassidic rabbis did not wear rings, especially not in 1956, so he asked him about it, and Zalman told him it was a Masonic ring.
“Yossele asked Zalman whether he was a Mason, and Zalman said yes. Yossele was most shocked, because, as far as he knew, the tenets of Masonry contradicted Torah. However, he did not press the issue.”
And neither does Rabbi Dalfin in the book. What he does instead, for the most part, is offer what other people had to say about Rabbi Schachter, often quoting newspaper articles that were written about him over the years.
Rabbi Schachter was also a follower of the late, esteemed head of the Lubavitcher movement for many years, Rabbi Menachem Mendel Schneerson, the Lubavitcher Rebbe. Despite the controversy associated with Rabbi Schachter throughout his adult life – and even somewhat before he became an adult, it seems, Rabbi Schneerson seemed to adopt a very patient stance when it came to tolerating Rabbi Schachter’s often shocking behavior. But, as Rabbi Dalfin notes, it might have been a bit much for Rabbi Schachter to claim, as he did, that he had Rabbi Schneeron’s blessing to take LSD.
Given how animated that December 2016 evening was when the subject of Rabbi Schachter was put out for discussion among a Winnipeg audience, one would think that a reprise of that evening would be in order, but this time there would be a book that could serve as the basis for discussion. (As my 2016 article noted, the only available accounts of Rabbi Schachters’ time in Winnipeg – to that point, were oral interviews given by 28 Winnipeggers that now reside in a collection at the University of Colorado in Boulder.)
“The Real Zalman” does much to complete the missing gaps in what we have known about a fascinating figure.

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.
