Campus program gives Winnipeggers a virtual reality experience allowing them to share some of the same emotions Israelis attacked on October 7 felt
By BERNIE BELLAN It was advertised as “Through Their Eyes – October 7th Virtual Reality Journey.”
On September 16, a small number of Winnipeggers were able to participate in a virtual reality experience during which they were able to watch in 3D as different Israelis described what they went through on October 7 last year.
The event was sponsored by Winnipeg Friends of Israel and Bridges for Peace. It was held in the games room of the Rady JCC.
As readers no doubt recall, on October 7, 1200 Israelis (and non-Israelis) living in communities situated close to the Gaza Strip were murdered by what turned out to be over 6,000 Hamas terrorists who had managed to penetrate into Israel fairly easily in the early hours of October 7. As well, 220 individuals (not all of whom were Israeli) were abducted and taken to Gaza.
While almost anyone in the world with access to the internet would have been able to see footage of the atrocities carried out by Hamas – and fully understand the absolute terror that people were experiencing, for Israelis living near the Gaza Strip what was happening was all so terribly confusing. People could hear gunshots all around them – but where were they coming from and who was firing them, almost everyone who was there must have wondered?
And, once the realization that an attack was underway, how were you supposed to respond? Were you better off to try and hide in place or to try to make a run for it?
An Israeli production company that goes by the name of Atlantis-VR embarked upon an ambitious project whereby they wanted to interview some of the individuals who experienced that October 7 attack directly. But, rather than simply interviewing those individuals, Atlantis-VR wanted to show each of them in their own homes – in the exact places they were as the attack was taking place. Through virtual reality technology viewers are now able to see a 360° rendition of an entire room in which the interviewees in the presentation created by Atlantis-VR were situated at the time of the attack. At certain points you are also taken outside interviewees’ homes and see the same vistas that those individuals would have been able to see, including roads and fields with the Gaza Strip in the background.
As groups of six different individuals entered the games room in the Rady JCC on September 16 they were greeted by Daniel Zioni, one of the principals behind Atlantis-VR. There were six different sessions held on September 16, each lasting anywhere from 40 minutes to an hour (depending on how long it took each attendee to watch the presentation. In my case, for instance, I spent over an hour as I had so many questions during the course of watching the presentation that I continued to pepper Daniel with questions about what I had just seen after each segment. Poor Daniel – since each of us had donned the headset at different times and were watching the presentation at our own pace, he was constantly racing from participant to participant, adjusting headsets, turning on the next segment, and answering questions.)
After donning the virtual reality headsets, (which takes some getting used to, especially for older participants who had likely never experienced wearing a VR headset before), the first segment began for viewers. We watched as a woman by the name of Yasmin Margolis describe what had happened to her, her husband Sa’ar, and their two young daughters, when Hamas terrorists entered Kibbutz Kissufim, which is where they lived.
Sa’ar bravely left the family home, armed with his rifle, to take on the terrorists. Unfortunately, while his wife’s and daughters’ lives were spared, Sa’ar died that day fighting to protect his kibbutz.
The next segment is about the Marom family, who were living in Kibbutz Re’em. In their case, their house was set on fire by terrorists while they were inside. Still, they managed to escape through a window and were eventually rescued.
The third segment shows a family living in an apartment block in Sderot. The battle for Sderot actually lasted over two days, as IDF forces entered into protracted gun fights with terrorists who had been hiding throughout the city. During that time the Politi family holed themselves up in their apartment and even provided shelter – and food, for a boyfriend of one of their daughters – and his friend, who had found themselves stranded at a gas station where one of them had been working when the terrorists invaded. There was a moment of comic relief when the Politi husband and wife described what happened when they heard banging on their apartment door. The boyfriend shouted that it was him – and Mr. Politi opened the door. At that point, Mr. Polliti, noted, the boyfriend’s friend said: “I’m hungry – have you got anything to eat?”
The final segment of the VR presentation – and easily the most mesmerizing of the four segments, consists of an interview with Rami Davidian, who was a 58-year-old member of a moshav by the name of Patish in an area very close to where the Nova Music Festival was taking place. Davidian has become quite a national hero in Israel for what he did on October 7 – and for almost 48 hours non stop thereafter.
As he describes in his interview, he received a phone call from a friend who didn’t quite understand what was happening the morning of October 7, but whohad a daughter who had been attending the Nova Music Festival, which was the site of the murder of 370 young Israelis. The friend knew Rami lived close to where the festival was taking place and asked him whether he could go there to try to find his daughter. Of course, Rami had no idea what he was heading into – and, as he explains during the segment in which he tells his story, even as bullets and rocket propelled grenades began to be fired at his car, he continued on. He managed to find survivors of the massacre and transport them back to his home on the moshav, where his wife took care of them.
But then, he started to receive hundreds of messages from anxious parents who somehow had heard that Rami might be in a position to save their kids. He got back into his car and headed right back to the site of the festival – all the while being fired upon by terrorists. Somehow – and he says he doesn’t know how he survived, he managed to return to the site – over and over again, eventually incredibly helping to rescue 750 young Israelis.
The entire VR presentation is so vivid that I had only wished that more people could have seen it. I asked Daniel Zioni whether there were any plans to convert the four segments of the presentation into one video that, for instance, could be seen on Youtube? Granted, seeing it in VR makes more of an impact, but in terms of reaching a wider audience I wondered whether it might make sense to do what I had suggested. I was especially keen on seeing the segment with Rami Davidian turned into something that could be seen by a much wider audience. While Daniel didn’t give me a definitive answer, he did say that was something under consideration by Atlantis-VR.
In the meantime, if you would like to read more about Rami Davidian and his heroics, there are quite a few articles online that tell his story. Simply Google Rami Davidian.

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.
