Remis group hears thoughtful analysis of war in Ukraine
By BERNIE BELLAN It’s always interesting to hear perspectives on a story that occupies much of our attention from an individual who has first hand knowledge of that particular story.
Such was the case on August 4 during one of the regular luncheon get-togethers of the Remis lecture group at the Gwen Secter Centre when the guest speaker was Olexandr Shevchenko, a historian and interpreter who comes from Ukraine himself.
Shevchenko is also a part-time lecturer at the University of Winnipeg, where he has taught courses on Russian history and European Power Politics.
While you’d have to be oblivious to world events not to be aware of what’s been happening in Ukraine since the Russian invasion, which began on February 24, listening to Shevchenko putting things into a very broad perspective certainly helped those who were at the luncheon gain a much deeper understanding of how events were set on a collision course long ago – and which ultimately led to Russia’s totally unjustified invasion of a neighbor country.
Shevchenko’s talk was titled “Can democracy defend itself?” By looking back at certain key events that are often overlooked when one is fixated on the day to day events of the war such as what atrocities have the Russians committed lately? he was able to help audience members obtain a better understanding how Vladimir Putin could come to think that he could invade Ukraine with few consequences.
A pivotal event – and one that is hardly ever mentioned in coverage of the Russian invasion, according to Shevchenko, was the war in Georgia in 2008, when Russian troops entered into the former Soviet republic of Georgia on the side of the self-proclaimed republics of South Ossetia and Abkhazia. Russia has occupied parts of Georgia ever since.
At the time though, much of the world’s attention had turned to the severe economic recession prompted by the collapse of the sub-prime mortgage market in the United States and the ensuing deep dives that stock markets took around the world, leading to a prolonged economic crisis that lasted well into 2009.
It was also the year of the election of Barack Obama, Shevchenko noted. One of the first things Obama did when he was elected, Shevchenko observed, was call for a “reset” of relations with Russia. Shevchenko, I don’t think you’d be surprised to learn, was rather dismissive of President Obama.
Russia had already been laying the groundwork for an effort to restore its past dominance of Eastern Europe, but when its invasion of Georgia barely caused a ripple among the international community, the table was set for further aggressive behaviour, Shevchenko explained.
“Russia does not consider itself bound by the dissolution” of the Soviet Union in 1991,” he said. Thus, when it invaded the independent republic of Georgia in 2008, the lesson garnered from that, according to Shevchenko, was “anything goes.”
The next domino to fall in the cascading series of dominos that led up to this year’s invasion of Ukraine occurred in 2014, when a pro-Soviet president in Ukraine, Viktor Yanukovych, resigned as a result of a series of protests by Ukrainians who were in favor of closer ties with the European Union. In February 2014 Russian troops occupied Crimea. Shortly thereafter pro-Russian separatist forces began fighting Ukrainian forces in the eastern Ukrainian provinces of Donetsk and Lukansk, aided by Russian troops.
Rather than take aggressive action though, Shevchenko said that had the Russians done nothing, “Ukrainians would have squabbled among themselves,” thus leading to disunity. Instead the occupation of Crimea and the arming of separatists in the eastern provinces hardened Ukrainian nationalism.
In 2019 Vlodomyr Zelensky was elected president of Ukraine when he headed a party known as the “Servant of the People Party.” In Shevchenko’s opinion, the party was made up of “extreme dreamers.”
“In some respects, Ukrainians electing a former comedian might have sent the wrong message to the Russians,” Shevchenko observed.
While Zelensky was hardly taken seriously by other world leaders, viz. Donald Trump’s attempt to manipulate him into saying that Hunter Biden had been engaged in corrupt business activities in Ukraine, Ukrainian themselves were hardly united in opposing Russian attempts to influence the course of Ukrainian history at that point.
Shevchenko told this joke to illustrate his point:
“Question: What is one Ukrainian?
“Answer: “A fighter.
“Question: What are two Ukrainians?
“Answer: A fighting unit.
“Question: What are three Ukrainians?
“Answer: A fighting unit with one traitor in it.”
The Russian invasion of Ukraine on February 24 was modeled after the Soviet invasion of Czechoslovakia in 1968, Shevchenko observed. The notion was that it would be fairly easy to topple the Ukrainian government and replace pro-democracy officials with Russian acolytes.
Unfortunately for Putin, things didn’t turn out the way he envisioned, but the consequences of the Russian invasion are likely to be felt around the world for years to come, Shevchenko predicted.
“We’re quite likely to see a bunch of regional wars around the world,” as the foundations of the world order that were established after World War II come undone – and stronger states feel empowered to attack weaker ones, he suggested.
Returning to the title of his talk, Shevchenko asked: “If democracy is defeated in Ukraine, what message does it say to the rest of the world?”
The answer, he said, is “it’s best to seek accommodation with your neighbours.”
As far as world organizations are concerned, Shevchenko said, “the UN is a joke. One of its primary purposes is the prevention of aggressive wars.” It wasn’t very effective in stopping Russia’s invasion, was it?
Further, Shevchenko asked: “Can a democracy defend itself?”
The answer, he suggested, was that “if it starts acting on real problems” and concerns itself “with the security and well being of its citizens,” then it can defend itself. (As an aside though, I have to admit that Shevchenko’s example of a democracy digressing from concerning itself with real problems was the debate over whether Portage and Main should be open to pedestrians. I wonder whether he might have been able to find a better example.)
Continuing in the vein of opportunities that were missed earlier to send a strong message to Russia that aggression toward its neighbours would not be tolerated, Shevchenko observed that another missed opportunity came when Turkey applied to join the European Union (a process that has been ongoing for years).
“Acceptance of Turkey into the European Union could have sent a message to the Muslim world,” Shevchenko suggested, that a state can be both democratic and Muslim.
Answering questions from attendees at the luncheon, Shevchenko was asked how long he thought the current war will go on?
There may be a “window of opportunity” this fall, he answered. Certainly, if it drags on there will be another opportunity when the US holds mid-term elections in November, he added (without quite explaining why).
But what if Russia emerges victorious – or at least claims to have achieved victory? What then? Shevchenko was asked.
“Could we have a puppet Ukraine?” “Possibly,” was the answer. But, would that lead to a more “docile” Russia? he wondered.
“I seriously doubt it,” Shevchenko said, answering his own question. “Who’s next? Finland? Poland?”
There are three possible outcomes to the fighting, Shevchenko explained:
“One shot in the Kremlin could end it all.
“Stalemate.
“The defeat of Ukraine”
(Shevchenko did not describe a scenario in which Ukraine beats back the Russians.)
Finally, Shevchenko offered this novel observation about which country’s behaviour might affect the long-term outcome of the war in Ukraine the most: the United Kingdom.
“What worried me the most from the beginning were the actions of the U.K. government,” Shevchenko said (without explaining why he was focusing on the U.K. rather than say Germany, which seems to be far more vulnerable to Russian threats than other European countries).
“What will happen in the upcoming winter” (when gas supplies could very well run short throughout Europe)? Shevchenko asked.
“The population may say ‘Wrap it up. We can’t have it any more.’ “
Really though, that’s what Putin is counting on, isn’t he – that European unity will evaporate and support for Ukraine will diminish to the point where he will achieve at least some of his original goal of disassembling the Ukrainian state.
So much to ponder. Olexandr Shevchenko certainly gave his audience something to think about – at a time when discussion of the war in Ukraine doesn’t usually occupy typical lunchtime conversations, does it?

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.
