Arthur Ripstein: Following the Ripstein trail first laid in Manitoba 140 years ago
By GERRY POSNER Let me be clear. The Ripstein family has been a force in many ways in Winnipeg, in Manitoba and indeed in the entire country of Canada now for almost140 years.
In fact, in 1873, Jacob Ripstein began a series of many firsts in the family.
He was one of the very first Jewish settlers in Manitoba and one of his sons, Simon – a brother to Arthur Ripstein’s great-grandfather, Isaac, was among the very first Jewish children born in Winnipeg.
Isaac’s son, Reg Ripstein was, in his own way, the leader in another way. He made the first ever trade in canola in 1963 as a futures broker in a career that lasted 72 years. His wife, Ellen Ripstein later became the first ever female stockbroker in Canada, also the oldest stockbroker in Canada – working until she was 90, seven weeks before she died. Even a Ripstein cousin, Ellen became the world crossword puzzle champion. Thus, the foundations were laid for Reg and Ellen’s two sons, Ira and Arthur.
Readers in Winnipeg will likely be familiar with the name Ira Ripstein. Ira is a well known doctor in Winnipeg, also an Associate Dean at the Faculty of Medicine at the University of Manitoba. Brother Arthur Ripstein has also ascended to some very lofty heights in his career as a philosopher and educator. You would need a book to recite the starred story of Arthur Ripstein, but here is the Reader’s Digest version:
Just recently, Arthur Ripstein was awarded the 2021 Killam Prize in humanities, awarded by the Canada Council for the Arts. Aside from the significant distinction that goes with receiving this prestigious honour, there is a little stipend that goes along with it, as in $100,000.00. So for all you parents worried about your kid’s desire to go into the Faculty of Arts – there is hope.
Consider this: Ripstein is a leading scholar of the legal and political works of the 18th Century philosopher, Immanuel Kant. Succinctly put, “about Kant, with Ripstein you can”.
Ripstein’s scholarship covers many areas, including justice, tort law and even the law of war. To have achieved this lofty status Ripstein points to his early years spent at the University of Manitoba, specifically his time in the Department of Philosophy. There he was introduced to and, as Ripstein acknowledges, was significantly influenced by Professor Arthur Schafer, the then head of the department.
Moreover, Ripstein benefited from being a member of a small department, where he received attention and encouragement. After Ripstein obtained his BA from the University of Manitoba, he was off to the University of Pittsburgh, which had a strong graduate school philosophy department.
His dissertation there landed him a teaching job at a small college, Franklin and Marshal. That stint enabled him to get connected to the University of Toronto, where he came under the tutelage of a law professor by the name of Ernest Weinrib. That relationship helped propel Ripstein to Yale Law School for a special PhD program, in which he took a year of law.
Next up for Ripstein was a period spent at Princeton as a Rockefeller Fellow at the Centre for Human Values. His last stop (so far) was – and has so far been at the University of Toronto law school, where now Dr. Ripstein started teaching torts to first year law students.
As Ripstein states, “it is the most fun course to teach because it is about such fundamental questions – how people are allowed to treat each other, whose problem is it when something goes wrong.”
It’s been a challenging and satisfying path that’s led to his present position, but Arthur Ripstein’s career has, I suggest, really taken off since he joined the University of Toronto. He is both a professor of law and of philosophy there. By now, he is the author of four monographs, over 75 essays in academic journals and has edited, either alone or with a partner, four books.
Twice he has been awarded the Canadian Philosophical Association (did you know there was such an animal?) Book Prize. He was also the recipient of a Killam Research Fellowship between 2018-18. And. by the way, if you’ve ever listened to the CBC radio show “Ideas”, guess who’s been a very frequent contributor: Arthur Ripstein.
In addition, Ripstein delivered the keynote lecture at the World Kant Congress and the 2019 Tanner Lectures on Human Values at the University of California, Berkeley.
Ripstein has reflected on topics that affect all of us at some point, relating to matters of authority, rules of war, the legitimacy of coercion and the complexity of obligation. I particularly liked his response to the question which children often ask their parents, as in “Why do you get to make the rules?”
Ripstein suggests “Because I said so” is not the appropriate answer. When you address the possible answers, you embark on a philosophical journey.
Even more pertinent these days is his response to the question “What is the place of authority during the present pandemic?”
Ripstein looks at it this way: “The hard question is figuring out why authority is legitimate. Some critics of public health measures seem to think that they must be illegitimate because they stop people from doing things that they want to do. That cannot be the right way to think about it; human beings can only live together if they are subject to common rules and those rules sometimes require depending on experts. The philosophical challenge is to articulate its proper limits. This is one example of how philosophy can take on such vital relevance to contemporary questions.”
Who could have predicted the career of Arthur Ripstein? Maybe it can be traced back to the original Ripstein settler in Winnipeg. Surely Jacob Ripstein in 1873 could never have envisioned his great-grandson, Arthur reaching such a high level in Canada and indeed around the world. In his own way, winning the Killam Prize and being recognized for an academic career in two disciplines, Ripstein has followed his Ripstein predecessors with a first, as in the first Jewish Manitoban to receive the Killam Prize. However you slice it, Arthur Ripstein has already made Jacob Ripstein’s decision to come to Canada a very wise one. Why do I say that?
Someone who knows far better than I – as in The Chair of the Department of Philosophy in the Faculty of Arts and Science, at the University of Toronto, Martin Pickavé, has said of Arthur Ripstein: “Arthur Ripstein is one of the most important legal and political philosophers in the world. The Killam Prize could not have gone to someone more deserving….He is an inspiration not only to his students, but also to his colleagues.”

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.
