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.

Dating in New York after Oct. 7 was already painful. Then came Zohran Mamdani
By David Berkowitz October 31, 2025

I was considering getting back together with someone I dated earlier this year. When we reconnected this past summer, we hit it off again instantly. As we took in the sunset along the East River promenade, we reminisced about how easily the conversation had always flowed between us.
But then, she had to ask the question: “Who are you going to vote for?”
“I have to vote for Mamdani,” I said.
And that was the end of that. It became a Zohran Mamdani breakup. Or, Mamdani, the Democratic candidate for New York City mayor, torched the chances of us getting back together. I have him to blame — or thank — for that one.
Dating in New York City has never been easy. Dating here as a divorced 40-something Jewish dad seeking to meet other Jews in a post-Oct. 7 world, with an autocrat as president and a democratic socialist running for mayor, is almost impossible. There are so many political reasons to decide it’s not worth it to pursue a relationship with someone — even before determining how well you’d really get along.
When I resumed using dating apps this spring, after the end of my first long-term relationship following my divorce, I noticed that way more Jewish women in their 30s and 40s were listing their politics as “moderate” than I’d ever seen before. Many of them showcased Israeli flags or Stars of David in their bios or noted something positive about Israel or Zionism.
As I began chatting with potential interests, I learned that for some women, the aftermath of the Oct. 7 attack had transformed them from social liberals into supporters of President Donald Trump, due to Republicans’ perceived alignment with Israel’s interests. Others were liberal and perhaps even progressive in many of their views, but adamantly Zionist. They were thus much more conservative than me when it came to any question about Israel’s right to keep prosecuting a war with an exceptionally high civilian death toll.
Being back on the dating scene was a minefield. And then Mamdani’s stunning surge in the Democratic mayoral primary began.
I wasn’t ready to vote for Mamdani in the primary, instead ranking his Jewish ally, Comptroller Brad Lander, first. But the more I learned, the more comfortable I was with Mamdani’s vision and plans for New York. And he’s running for mayor of New York City, after all, not Tel Aviv.
Yet what I found: With many potential dates, even an allusion to Mamdani would halt any progress in its tracks.
Just this month — ironically, on Oct. 7 — I was having a pleasant back-and-forth with someone on Lox Club, the supposedly selective dating app for Jews with “ridiculously high standards.” I was increasingly eager to meet her: She was bright, pretty, well-traveled, and, most importantly, starting to find me hilarious.
She lived in Manhattan, like me. But when I asked about where she’s from, she said she’s from Long Island and that she’ll likely move back after the election if Mamdani wins.
Part of me was tempted to say whatever was needed to at least score a date. I could have done the texting version of smiling and nodding, perhaps validating her fears and saying I’m worried too. But I suspected I’d be wasting my time pretending we could accommodate differing outlooks on the city’s future. I texted her that I’m convinced a Mamdani administration would be way better for the city than most people fear. Still, it seemed our views were too divergent, as much as I’d have loved to meet her. She agreed, and I ruefully tapped “unmatch.”
In some ways, it seems frivolous to lament the plight of diaspora dating. The trauma experienced by Jewish daters in the comfortable environs of New York City can’t possibly be compared to the trauma of those who experienced the terror of Oct. 7, or the suffering of Palestinian civilians in Gaza during the subsequent war.
But there’s a real cost to Jews becoming more suspicious of one another. We risk isolating ourselves into smaller and smaller blocs, making it harder for us to connect once we find each other.
It also means that those who take a less reactive and more nuanced view wind up silencing themselves. How can I express that my heart was torn apart every time I heard first-hand accounts from freed hostages who returned to Israel — but that I also grieve deeply over the devastation in Gaza? How can I admit that former Gov. Andrew Cuomo has a good track record in connecting with Jewish voters and would likely reliably stand up to antisemitism, but be more compelled by Mamdani’s infectious love for New York City — and believe his criticism of Israel doesn’t make him an antisemite?
And how can I express my love for Israel — the idea of it and its people, though not necessarily its government — while voting for a candidate who questions Israel’s viability as a Jewish state?
For too many Jewish daters like myself, there is increasingly a sense that looking for someone who is also willing to take an open-minded approach to conflicting political truths is like praying for a miracle.
There was one promising moment, before my springtime interest and I decided not to renew our romance, that gave me hope. My date and I watched an episode of Real Time with Bill Maher, one of her favorite shows, together. I hadn’t seen his show in so many years that I was game to see why she enjoyed it so much.
I was surprised she could find humor in someone so critical of Trump, the president for whom she voted. She was surprised I could agree with a lot of the centrist views from Maher and his guests, most of which didn’t toe the progressive line. I told her that night that if things worked out between us, we’d have to invite Maher to our wedding.
That obviously didn’t happen. But I still think we need more moments like that — opportunities to appreciate both our commonalities and differences. I could envision another version of that relationship, where we end up listening to different podcasts and following different Instagram accounts, but still find areas where we can share similar perspectives and laugh at the same jokes.
I’m skeptical, and disheartened. But I’m still holding out hope for some future “Maher weddings” — even though with every swipe right or left, it feels increasingly naïve to think that. And yet, at heart, I’m a Jew, and I’ve studied enough of the history of the Jews to know that we’ve been through worse. We’ll get through this. But not before more anniversaries of Oct. 7 have passed.

Guest Article — A Canadian Jewish Traveller’s Money Playbook: Smarter FX & Safer Digital Finance for Israel Trips and Beyond
Written for readers of jewishpostandnews.ca
Whether you’re flying to Israel for a simcha, helping a student with a gap year, supporting family abroad, or making a donation to a cause you care about, the way you move money matters. Small choices around foreign exchange (FX), card settings, and digital security can quietly cost—or save—you hundreds of dollars per trip. This guest guide keeps things practical and non-hyped, with steps you can use right away.
1) Foreign Exchange: Focus on the all-in cost, not just the posted rate
Most leaks happen in three places: spreads (the markup over interbank), fees(ATM/operator/bank), and terminal settings (dynamic currency conversion, or DCC).
Winnipeg-to-Israel routine (works for most routes):
1. Always pay in the local currency. In Israel, choose ILS at the terminal; in the U.S. leg of a connection, choose USD. Decline DCC—letting the terminal convert to CAD usually costs more.
2. Separate rails by purpose.
○ Everyday spending: use a low/no-FX-fee card.
○ Larger cash or transfers: get a quote from a specialist and compare with your bank’s total cost (rate plus fees).
3. Stage big conversions. If the rate feels jumpy, split a large exchange into two or three tranches to average your price.
4. Carry a small cash float. Enough for taxis, tips, markets, and rural stops—then default to card for everything else.
5. Log your effective rate. Screenshot ATM and card receipts so you can see the actualCAD cost later.
Starting point to benchmark retail quotes: check posted rates, ID requirements, and pickup logistics via currency exchange in Ontario (useful if you or your student connect through Toronto/YYZ or spend time in the GTA before departure).
2) Israel-specific tips (simchas, tours, and longer stays)
● Hotels & car rentals: expect hefty holds on credit cards; keep extra available limit to avoid declines.
● Transit & payments: most urban vendors take cards, but small kiosks and markets may prefer cash; keep some small ILS notes.
● Receipts for donations & tours: store PDFs in one folder (cloud + offline) with a simple naming format (YYYY-MM-DD_vendor_amount). It saves time at tax season and for warranty/claim issues.
3) Tuition, program fees, and family support
Moving four- or five-figure sums? The spread matters more than you think.
● Shop the spread: get at least two quotes on the same day (bank vs. specialist).
● Confirm the lock: ask how long the rate-hold window lasts and the funds-received cut-off to avoid re-quotes.
● Proof of payment: save wire confirmations and the beneficiary’s receipt; mismatched names or references can delay admission or housing.
4) Tzedakah and cross-border donations (general guidance)
● Ask for the right receipt: Canadian tax receipts require a registered Canadian charity number; many Israel-based organizations partner with Canadian affiliates—ask before you give.
● Card vs. wire: cards are fast but may carry higher total cost on large gifts; wires are slower but can be cheaper for size.
● Record-keeping: store the acknowledgement email, PDF receipt, and card/wire confirmation together.
(This section is informational—always seek professional tax advice for your situation.)
5) If you hold a little crypto (optional)
Crypto isn’t for everyone, but if you already hold some—or your student does—treat it like an operations problem: keys, backups, and off-ramps.
Minimum viable safety
● Self-custody for long-term funds: use a hardware wallet; keep a small hot-wallet only for spending.
● Never store seed phrases in email or cloud notes. Write them down and secure them (consider splitting and sealing).
● On/off-ramp drill: before you travel, do a tiny test withdrawal to confirm access and speed; save TX IDs and exchange statements.
If you’re scaling exposure or want a security-first setup (custody architecture, recovery run-through, incident response), consider a session with crypto investment consultants.
6) One-page checklists you can save
Travel Day (Israel or U.S. connection)
● Card set to pay in local currency (decline DCC)
● Small test purchase completed on arrival
● Shortlist of ATMs with known operator fees
● Cash envelope for day-one expenses
● Offline copies of bookings + insurance on your phone
Large FX Transfer (tuition/deposit/donation)
● Two quotes captured (bank vs. specialist)
● Rate-lock window and cut-off confirmed
● Screenshots with timestamps saved
● Wire confirmation + beneficiary receipt filed
Crypto Hygiene (if applicable)
● Hardware wallet initialized; seed written and stored safely
● 2FA keys offline; password manager updated
● Test withdrawal completed; TX IDs logged
● Quarterly: verify balances, rotate credentials, re-test recovery
jewishpostandnews.ca serves readers with local, diaspora, and Israel coverage—readers who routinely plan Israel trips, support causes, and help students abroad. Practical money ops reduce friction on exactly those journeys.
Bottom line (and a small disclaimer)
You don’t need to “time the market.” Use the cheapest reliable rail for each job, avoid DCC, stage large conversions, and keep clean records. If crypto is in your mix, run it with production-grade safety. This article is informational only, not financial, tax, or investment advice; consult qualified professionals for your circumstances.
