Tafsik: Canadian organization created in wake of October 7 has played leading role in combating anti-Israel hatred
By BERNIE BELLAN It was prior to an event featuring Col. John Spencer speaking here on September 11 that we first became of something called “Tafsik.” We had received an email from whatever Tafsik was, inviting us to attend the Spencer event, but there was absolutely no information contained within that email explaining what Tafsik was.
Then, at the actual event, there was the logo for Tafsik emblazoned on a screen overlooking the stage at the Berney Theatre where Spencer spoke. Granted, there were logos for other organizations as well, but the Tafsik logo was larger than any of the others.
We were intrigued by the notion that an organization about which we knew nothing had been involved in bringing a notable expert on urban warfare to our city – and who has established a fierce reputation as a defender of the Israel Defence Forces, so we contacted Adam Levy, Publlc Relations and Communications Director for the Jewish Federation, to ask him whether he knew anything about Tafsik?
Adam said he didn’t and referred us to the organization’s website.
When we sent an email to Tafsik directly, asking who was behind them and what they were all about, we received a rather generic reply containing information that was already available on its website, but which left us even more intrigued as to who was behind it:
“Tafsik organization emerged resolutely from the tragedy of October 7th, dedicated to combating Jew Hatred in Canada and beyond. By forging alliances with diverse communities—including Iranian, Indian, Christian, Yazidi, Venezuelan, and many other groups—Tafsik is uniting voices against Jew hatred on a global scale. The organization hosts significant events featuring prominent figures such as Douglas Murray, Gad Saad, Hillel Fuld, and Colonel John Spencer, to illuminate the challenges faced by Israel and the Jewish community worldwide. Additionally, Tafsik is leveraging cutting-edge AI technology to combat Jew Hate more effectively. As one of the fastest-growing grassroots organizations in Canada, Tafsik is committed to fostering understanding and solidarity in the fight against hatred.”
Then, on September 30, we received yet another email from Tafsik, this time advertising the upcoming appearance in Winnipeg (on October 22) of well-known Columbia professor Shai Davidai.
If you don’t know who Shai Davidai is, he came to prominence soon after October 7 last year when Columbia University in New York City became a hotbed of antisemitism, where Jewish students and professors alike were being intimidated into silence – and fear for their physical safety, by fiercely antisemitic mobs that were being allowed to run rampant on that university’s campus.
A Youtube video appeared of Davidai speaking to Jewish students at Columbia, in which he spoke quite emotionally about how “unsafe” he felt at Columbia – and it quickly went viral. (You can watch that video at https://www.youtube.com/watch?v=VPVe2CsBqmM or simply by entering “Shai Davidai” in the Youtube search bar.)
So – two well-known speakers – John Spencer and Shai Davidai, both sponsored by an organization called Tafsik – about which we still knew very little. We were determined to find out who was behind Tafsik. We sent yet another email to the organization, but this time we were rewarded with a very expansive reply – this time from the organization’s founder directly, someone by the name of Amir Epstein.
Here is what Epstein wrote to us, in response to our suggestion that the original email we had received from Tafsik explaining what the organization wall all about was rather generic in its content:
“I apologize for the ‘generic’ explanation as to what Tafsik Organization is all about and our accomplishments. I hope my overview below satisfies any curiosity and questions you may have. I’m always happy to answer any specific questions I didn’t touch on.
“I cofounded Tafsik Organization after October 7th in response to the complicity I witnessed in the communities I have dedicated my life to defending. Suddenly, our community found itself isolated. I recognized that the rise of antisemitism in Canada had eroded our institutions, such as our universities, school boards, unions, media, and politics, all leading to a troubling apathy toward the horrific attacks on our people in Israel.
“As a law graduate who briefly worked in criminal law and previously owned a successful tech company in the food and beverage industry, I felt compelled to take action. I realized our community faced a serious existential threat. I approached my tech colleague, Bryan Lipovetsky, who had built my companies framework and website, and together we launched Tafsik Organization. Initially, we acted quickly, driven by a desperate need to help, although we were still defining our purpose and how best to combat the overwhelming hate directed at Canadian Jews.
“Our focus became twofold: building alliances and leveraging technology to combat antisemitism. In February, we launched TECAH (The Emergency Coalition Against Hate) alongside the remarkable Douglas Murray in Toronto, quickly becoming Canada’s fastest-growing grassroots ally-building organization. We have formed strong connections with the Indian and Iranian communities, commemorating significant events such as the anniversary of the Air India bombing, the murder of Mahsa Amini, and the genocide in Bangladesh. We have also engaged with various communities, including Venezuelan, Afghan, Arab, Chinese, and Black communities, and are working closely with Sheikh Mirza Ismail on reunifying Yazidi families still in refugee camps in northern Iraq with their relatives in Canada.
“Additionally, we have built meaningful relationships with leaders in politics, including some of the top politicians in our country. We understand the critical role their government positions play in protecting our community.
“We have hosted numerous sold-out events featuring prominent speakers like Douglas Murray, Gad Saad, Hillel Fuld, and Colonel John Spencer, with an upcoming event featuring Shai Davidai. These events aim to present the truth to diverse communities within our city.
“On the technology front, we are actively seeking funding to develop AI software capable of identifying individuals and accounts online that glorify terrorism. This technology will assess account histories, such as comments, likes, and posts, to evaluate potential radicalization and threats. Our goal is not commercialization but to provide law enforcement with tools to prevent real danger and violence against our community and others.
“In response to the overwhelming amount of antisemitic graffiti in Toronto, we are developing a new app called ‘Graffiti Watch’ that will map instances of hate speech in public spaces, empowering our community to take action against it. Graffiti Watch will be free to download.
“While our primary focus is on ally building and technology initiatives, we occasionally respond to urgent needs outside these pillars. For instance, this past June, we received a request via WhatsApp to help children from Kibbutz Kfar Szold, who were under missile attack from Hezbollah. When a major organization in Toronto declined to support this initiative, we launched a GoFundMe campaign and successfully raised more than we needed. As a result, we flew 15 children to Canada, where they attended Camp Northland and enjoyed a week of fun activities, including visits to Canada’s Wonderland, Niagara Falls, Ripley’s Aquarium, and a shopping spree. We also organizers a big dance party for the children, fostering new friendships with children from our community. Again, all free of charge. We are not a business. We are a non profit, and soon to be charity. Everything we have done has been self funded by me and a little money from donations, with exception to the Israeli kids who we brought with donations.
“This past year has been incredibly successful, exceeding our expectations. We now have just under 10,000 subscribers on our mailing list and a growing social media presence, including followers like Douglas Murray, Aviva Klompas, The Imam of Peace, Eylon Levy, and Colonel John Spencer to name just a few. These leaders recognize us as a driving force in Canada, dedicated to protecting our community and helping those in need.
“I hope this clarifies who we are as an organization and what we aspire to do.”
We thanked Amir Epstein for his quite expansive explanation, not only about how Tafsik came about, but who he is. We asked whether he’d be willing to send us a photo of himself and he readily agreed.
By the way, we’re not sure if there are still tickets available for Shai Davidai’s appearance here on October 22, but if you’re interested in attending you could try this link: www.tafsik.com/shai-winnipeg

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.
