Not without honour…..except here
By SIMONE COHEN SCOTT Several Wednesday nights ago, June 22nd to be exact, I attended a launching here in Winnipeg, at the Whodunit Bookstore to be exact, of Celia Rabinovitch’s book, “Duchamp’s Pipe; a Chess Romance.” Actually, the book has been launched in a few places, mostly via zoom. Readers of this paper may even remember that I reviewed her book a while back.
(Ed. note: It was actually December 2020, Simone – and your review is on our website at http://jewishpostandnews.ca/8-features/640-new-book-by-noted-art-expert-celia-rabinovitch-explores-many-themes.)
Anyway, the event back in June was delightful. The evening was basically a conversation between Dr. Michael Bumsted, proprietor of the store, and Celia Rabinovitch, internationally celebrated, locally barely known, artist, writer, and cultural historian. They were well-matched, the extremely erudite Dr. Bumsted, educated in Scotland, and Celia, Director of University of Manitoba’s Fine Arts Department, 2002-2008; scholar-in-residence at universities in North America, Europe, and Israel; her paintings appearing in art centres throughout Canada and the United States albeit seldom here. His questions about the book were incisive and penetrating, her answers thoughtful, informative, interesting, and amusing. She is a wonderful raconteur and his method encouraged her to tell of the many adventures that went into the researching and writing the book. It was apparent he had read the book carefully and had had fun doing so.
Of course they talked about pipes, but also about bohemian life in various cities throughout two continents during the war-dominated decades of the early 20th century, travelling via tramp steamer, partying with the privileged, barely eking out a living. Histories at several levels are revealed through the medium of chess tournaments, against the backdrop of a not so unlikely friendship, that of George Koltanowski, a passionate chess playing phenomenon who practically breathed the game, (Good heavens, he could play several opponents at once, blindfolded, and win!), and Marcel Duchamps, the sophisticated chess aficionado, who had already made his name initiating a startling genre into the world of art with his ‘Nude Descending a Staircase’. The central character is the pipe; it provides the theme connecting the two men who, in fact, spend just scraps of time with each other over the decades-long era their stories cover. Both Bumsted and Rabinovitch are well versed in many aspects of early 20th century histories in several locales. The audience, seated on metal folding chairs in the centre of the store, half-emptied platters of goodies behind them, had their horizons broadened. There was a flurry to buy the book after this presentation.
My own friendship with Celia began through a mutual friend, actress Terri Cherniak. Celia was to spend a couple of weeks as scholar-in-residence at the Israel Museum, lecturing on Dada art, and Terri knew I had an apartment nearby. She put us in touch. We were roommates for two weeks, we hit it off, and a friendship grew. Celia is, to me, a citizen of the world. She has an aura about her that makes one feel something special is going on. She is aware, always, of the spiritual connection between people, their settings, the objects they love, and she perpetuates the idea that the love passes along with the object. This informs her paintings, and this is the story of the pipe. The thread of love connection permeated every aspect of its journey as the gift from Marcel to George and beyond, (George re-gifted it), until finally, because it was Duchamp’s pipe, it was auctioned off for tens of thousands of dollars. Perhaps the pipe is laughing now.
A second perspective of the thread of love, binding the souls of the two men, is the game of chess, which accounts for the rest of the book’s title, ‘a Chess Romance’. One feels as one reads the book that little wisps of je ne sais quoi are whirling about in the atmosphere, twirling themselves around your mind, giving it ideas. Of course, anyone familiar with Celia’s previous book, entitled “Surrealism and the Sacred: Power, Eros, and the Occult in Modern Art”.wouldn’t be surprised by this mystic quality. One senses it in her art as well. An unidentified quote sums it up thus: “Her luminous paintings evoke mood, atmosphere, and ambiguity, leading to a sense of the uncanny.”
The Whodunit Bookstore has a story too. It was founded as an activity for Michael. Bumsted’s father when he retired. As a mystery buff’s oasis, it thrived. My own introduction to “Whodunit” happened when I began to winter in Israel; I asked the elder Mr. Bumsted to find me mysteries set there. The several he found for me added greatly to my grasp of the neighbourhoodsof the country. Mr. Bumsted was an historian and customers flocked to his evenings of readings and discussions, to hear his stories and to buy his recommendations. Soon Mrs. Bumsted, also an historian, was needed to help in the business.
That is when the merchandise begins to reach beyond thrillers. As Mrs. Bumsted would include books for her grandchildren in some of her orders, one day when a few were inadvertently left out on the counter, they were noticed and ultimately sold. It made sense; since people who like books have children and grandchildren – make it convenient for them. So children’s books were stocked, and then one thing led to another. When the space next door became vacant, Whodunit expanded to twice the size.
By this time, son (and recent PhD) Dr. Michael Bumsted had returned from Scotland. A career in a book store was not, I suppose, his intention, but hey! It turned out to be a good fit. As the range of books filled the shelves, his eclectic interests were being met. As I’ve already mentioned, I was impressed with erudite remarks and penetrating questions with which he drew out Celia’s fascinating anecdotes, and the ensuing discussion. If the evening sessions discussing books that he facilitates at Whodunit are as engrossing as the one I attended, you’ll see me at more.
A week and a half prior to this event, Celia spoke at the Manitoba Museum about the exhibit she curated there, of photographs taken by Nick Yudell, a first cousin of Celia’s once removed. Left in the possession of a family member, they were really a gift to Canada prepared for us by this young photographer – fated to die in WWII as an RAF pilot. Whereas a less sensitive person might have left them in their carefully labelled boxes, seeing how much love went into the taking of these photos, as one artist to another, Celia undertook to prepare them for display, to be shared with the world. At a point when we were together in one of the rooms of the display, Celia confided to me that she had wanted to convey the fact that although Nick’s photos feature his own community, which was Jewish, the story he is telling is about the every-man in Canada during the wartime period, that is, a story of patriotic men of courage and of strength. We who were children then, remember them. She surely succeeded; staff and patrons got it. The exhibit, originally meant to end August 1st, has been held over to December 18th.

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.
