ABC Learning Design: A Practical Guide to the Arena Blended Connected (ABC) Toolkit
Designing an engaging course is no longer about simply selecting content and sequencing topics. Today’s learners expect active participation, meaningful tasks, and an experience that blends digital and face-to-face learning in a seamless way. The ABC Learning Design Toolkit, also known as the Arena Blended Connected (ABC) Learning Design model, has become one of the most practical and widely adopted frameworks for educators who need a fast, collaborative, and highly visual approach to course design.
Whether you’re building a new course from scratch or redesigning an existing one, the ABC LD Toolkit provides a structured way to align learning outcomes, activities, and assessments—while keeping students at the heart of the design.
What Is ABC Learning Design?
ABC Learning Design is a rapid, co-design method originally developed at University College London (UCL). The goal is simple:
Help educators design engaging, blended learning experiences in 90 minutes.
It uses a storytelling approach, visual activity cards, and collaborative design steps to map out an entire module or course. The focus is on how students learn rather than just what teachers teach.
ABC is built on Professor Diana Laurillard’s Conversational Framework, which emphasizes learning as an active, iterative dialogue between learners, teachers, peers, and the learning environment.
The “Arena Blended Connected” Approach
ABC stands for:
Arena – a structured workshop environment (in-person or online)
Blended – combining digital and face-to-face elements
Connected – linking learning outcomes, activities, and assessments into a coherent journey
This approach helps curriculum teams work together—sometimes for the first time—to make design decisions visually and quickly.
How the Toolkit Works
The ABC LD Toolkit relies on six types of learning activities, each represented by a colour-coded activity card. These categories help instructors create a balanced, student-centred learning experience.
1. Acquisition (Read, Watch, Listen)
Students absorb content through readings, videos, demonstrations, or lectures. Common examples: textbook chapters, micro-lectures, podcasts.
These categories help instructors avoid over-reliance on lectures and ensure that students engage through multiple pathways—a key component of active learning and Universal Design for Learning (UDL).
The ABC Course Design Process
ABC Learning Design is typically done in a short but intensive workshop, usually 60–90 minutes. The process includes:
Step 1: Define the Learning Outcomes
Participants agree on the overall learning outcomes for the course or module.
Step 2: Map the Learning Journey
Using the activity cards, instructors design the sequence of learning events, week-by-week or unit-by-unit.
Step 3: Balance Online and In-Person Learning
For blended or hybrid courses, the toolkit helps ensure that each activity uses the right modality.
Step 4: Align Assessments
The team identifies formative and summative assessments and links them directly to outcomes and activities.
Step 5: Create the Learning Storyboard
The final output is a visual storyboard showing the entire course, making it easy to identify gaps, overload, or opportunities for improvement.
Step 6: Translate into the LMS
Once the design is approved, the storyboard becomes the blueprint for building the course in platforms like Blackboard, Brightspace, Moodle, or Canvas.
Why Educators Love the ABC LD Toolkit
✔ Fast and collaborative
Design that would normally take weeks can be completed in an afternoon.
✔ Clear alignment between outcomes, activities, and assessments
It prevents “content dumping” and supports purposeful, high-quality learning.
✔ Encourages active learning
The toolkit helps instructors shift from passive lecture-heavy teaching to interactive, student-centred learning.
✔ Supports blended, hybrid, and online learning
Perfect for modern post-secondary environments where digital learning is standard.
✔ Visual and engaging
The card-based design makes the process tangible and easy to follow—even for instructors with little instructional design experience.
The Role of ABC in Higher Education Today
Many colleges and polytechnics—including those in Canada—are adopting ABC LD as part of their curriculum renewal and digital learning strategies. It brings academic program managers, instructors, designers, and support teams together to build courses that are consistent, accessible, and aligned with institutional standards.
ABC is especially powerful when paired with:
Quality assurance frameworks
Course mapping
Competency-based learning
UDL and EDI principles
Learning analytics
The result is a teaching and learning environment that supports clarity, consistency, and student success.
Final Thoughts
The ABC Learning Design Toolkit is more than just an instructional design method—it is a collaborative philosophy that puts students at the centre of the learning experience. By simplifying course design and encouraging active learning, ABC helps educators create meaningful, blended learning environments that are engaging, efficient, and academically sound.
For instructors, program leaders, and institutions looking to modernize teaching practices, ABC LD offers a proven, practical, and accessible framework that can transform how courses are built and delivered.
Below is a 30–40 minute SMTP lesson plan suitable for college-level networking courses . It includes: purpose, tools, installations, commands, protocol operations, Telnet interaction, data formats, and references to typical Wireshark visuals (without reproducing copyrighted images).
📘 SMTP Lesson Plan (30–40 Minutes)
Topic: Simple Mail Transfer Protocol (SMTP) Audience: Networking / IT Students Goal: Understand SMTP purpose, workflow, commands, install & test SMTP on Ubuntu, and observe the protocol using Telnet & Wireshark.
1. Introduction (3–5 minutes)
What is SMTP?
SMTP = Simple Mail Transfer Protocol
Purpose: Transfers email from client → server → another server
Operates at Application Layer (Layer 7)
Uses TCP port:
25 (server-to-server)
587 (submission with TLS)
465 (legacy SSL)
When SMTP is used
Sending email from a mail client (like Thunderbird, Outlook).
SMTP uses simple ASCII-based commands. You can refer to standard diagrams online (e.g., RFC 5321 command flow), which show:
Client → Server commands Server → Client status codes
Common SMTP Commands
Command
Purpose
HELO / EHLO
Identify client (EHLO supports extensions).
MAIL FROM:
Sender envelope address.
RCPT TO:
Recipient address.
DATA
Begins message content.
QUIT
Close connection.
RSET
Reset session.
VRFY
Verify user existence (often disabled).
Common SMTP Status Codes
Code
Meaning
220
Server ready
250
OK
354
Start message input
421
Service unavailable
550
Mailbox unavailable
551
User not local
552–554
Message rejected
Reference: Online SMTP diagrams typically show a vertical message exchange: client commands on left, server replies on right, with arrows showing flow.
5. SMTP Workflow (4 minutes)
Step-by-Step Exchange
Client connects to port 25 → Server replies 220
HELO/EHLO → Server lists capabilities
MAIL FROM: → Server responds 250 OK
RCPT TO: → Server responds 250 OK
DATA → Server responds 354 End with <CRLF>.<CRLF>
Message body sent → End message with a single dot .
QUIT
This is the “Envelope + Content” model.
6. Hands-On SMTP via Telnet (8 minutes)
Connect to the local SMTP server
telnet localhost 25
Sample Full Exchange
Connected to localhost.
220 mail.yourdomain.test ESMTP Postfix
EHLO client.test
250-mail.yourdomain.test
250-PIPELINING
250-SIZE 10240000
250-STARTTLS
250-ENHANCEDSTATUSCODES
250 8BITMIME
MAIL FROM:<alice@client.test>
250 2.1.0 Ok
RCPT TO:<bob@server.test>
250 2.1.5 Ok
DATA
354 End data with <CR><LF>.<CR><LF>
Subject: Test Email
From: alice@client.test
To: bob@server.test
Hello Bob,
This is a test sent via raw SMTP.
.
250 2.0.0 Ok: queued as XYZ123
QUIT
221 2.0.0 Bye
What Students Should Notice
Interaction is plain-text, line-based.
Email has:
Headers (Subject, From, To)
Blank line
Body
Ending with . terminates DATA mode.
7. Listing Mails in the Queue (Postfix) (2 minutes)
Show queue
mailq
Remove queue
sudo postsuper -d ALL
8. SMTP Message Format (3 minutes)
Students can search for diagrams of:
SMTP envelope vs. email headers
RFC 5322 message structure
Typical Email Format
MAIL FROM: <sender@example.com> ← Envelope
RCPT TO: <receiver@example.com> ← Envelope
--- Data Section ---
Subject: Meeting Tomorrow
From: Sender <sender@example.com>
To: Receiver <receiver@example.com>
Date: Tue, 02 Dec 2025 13:15:00 -0500
Hello,
This is the body of the message.
Key concepts:
Envelope addresses ≠ Header addresses
Headers follow strict ASCII formatting
Blank line separates headers from body
9. Analyzing SMTP Traffic in Wireshark (5 minutes)
Tell students to search: “Wireshark SMTP packet details” images These images typically show:
What Wireshark Displays
TCP handshake (SYN, SYN-ACK, ACK)
SMTP commands as text under Application Layer
Status codes (220, 250, 354)
DATA block containing header fields and message body
Filters
tcp.port == 25
smtp
Things to point out
Application Layer tree expands to show each command.
DATA section shows full email contents.
No encryption on port 25 → Wireshark can see everything.
Students will notice:
How HELO/EHLO appears as plain text.
How the message body is captured.
How multiple packets represent a single message transfer.
10. Wrap-Up (2 minutes)
Key Takeaways
SMTP is the primary protocol for sending emails.
Simple plaintext command/response system.
Postfix provides a working SMTP server for labs.
Telnet allows manual testing.
Wireshark reveals how SMTP messages appear on the wire.
Optional Homework / Lab
Capture an SMTP session with Wireshark.
Send mail using sendmail or mail command.
Configure SMTP over TLS (STARTTLS).

Which ETF performed similarly to Bitcoin or closely? What performed the closet?
Asked ChatGPT:
I want to see which index ETF/fund performed as well as Bitcoin over the previous 10 years or 20 years. 2. How do XIT, QQQ, or Similar, S&P 500, FBTC compare with bitcoin performance? The primary concern is growth and gain. Volatility is a different concern, which is not currently the primary concern.
Great — I’ll answer both parts clearly and compactly, with numbers and sources so you can act on them.
Short answer (headline): Over the past ~10 years nothing in the major index/ETF world comes close to Bitcoin’s raw price performance — Bitcoin blew past even the best tech ETFs. The closest high-growth ETF (QQQ) returned strong equity gains but was far below Bitcoin. For 20 years you can’t meaningfully compare because Bitcoin doesn’t have a 20-year history.
Below I give a short comparison (table + commentary), the important caveats, and a practical takeaway for your decisions.
Time window: where possible I use 10-year trailing/typical published figures. Where a product is newer (FBTC) I note since-inception or latest trailing returns. All figures are pulled from market sources (links below each block).
Asset / ETF
Representative trailing CAGR (≈10y) or note
Source
Bitcoin (BTC)
~+70–75% p.a. (10-yr CAGR) — enormous outperformance vs stocks over the last decade.
casebitcoin / Bitcoin CAGR charts (summary of historical CAGR). (The Case for Bitcoin)
Invesco QQQ (QQQ)
~+19% p.a. (10-yr total-return CAGR) — very strong, tech-heavy growth ETF but far below BTC.
~+12–13% p.a. (10-yr CAGR) — long-run strong equity returns but well below QQQ and Bitcoin.
long-run S&P data / macrotrends / index backtests. (Curvo)
iShares S&P/TSX Capped Information Tech (XIT.TO)
Trailing performance is strong (multi-year gains), but not comparable to BTC over 10y; typical multi-yr numbers are high in recent years (e.g., 1-3-5y strong). See broker pages for exact trailing figures.
Fund inception: 30-Nov-2021 — too young for 10-yr comparison. Since inception & 1-yr figures show meaningful BTC-like returns in good years (e.g., 1-yr +60% in last 12m), but its track record only stretches back to 2021.
Key numbers (for emphasis): casebitcoin’s roll-up shows BTC 10-yr CAGR roughly in the 70%-plus range vs S&P500 ~13% and QQQ ~19% over roughly the same 10-year span. That gap explains why many investors say “Bitcoin crushed everything over the last decade.” (The Case for Bitcoin)
2) Important caveats & why direct comparisons are tricky
Different risk profiles. Bitcoin’s returns come with enormous drawdowns (30–80% crashes). If your priority is growth only you’d note BTC wins — but volatility matters in practice (timing, capacity to hold through drawdowns). (See Bitcoin historical monthly/annual swings.) (Curvo)
Survivorship / timeframe bias. Bitcoin’s 10-year performance includes its biggest multi-year bull run (2016–2021 etc.). A future decade could be very different. Past 10-yr winners aren’t guaranteed winners next 10-yr. (Financial Times)
ETF structure & fees. Spot Bitcoin ETFs (FBTC, BTCX, BTCO, BTCQ) hold underlying BTC and track price less fees. Equity ETFs (QQQ, XIT) hold stocks and pay dividends — their total return includes reinvested dividends. Fees and tracking differences slightly reduce ETF returns vs raw index/asset. (Fidelity Investments Canada)
Different starting dates. FBTC and most Canadian spot BTC ETFs launched only in the last few years — you can’t compute a 10-yr ETF track record for them. You must compare price Bitcoin itself vs older ETFs. (Fidelity Investments Canada)
Currency & tax effects. Your CAD returns depend on USD/CAD movement when holding US-listed ETFs; Canadian ETFs mitigate that somewhat. Taxes differ by account (TFSA/RRSP/non-registered). (Fidelity Investments Canada)
3) How XIT / QQQ / S&P / FBTC stack up vs Bitcoin (plain language)
Bitcoin — the clear top performer on raw price growth over the last decade. If you prioritized only absolute growth from 2015→2025, BTC is the winner by a very wide margin. (The Case for Bitcoin)
QQQ (tech-heavy) — very strong equity returns (~19% p.a. over 10 years). Great growth, but far from BTC’s magnitude. Adds diversification vs crypto and much lower realized volatility than BTC. (FinanceCharts)
S&P 500 — solid broad market growth (~12–13% p.a. over 10 years). Lower upside than QQQ but more diversified across sectors. (Curvo)
XIT (Canadian tech) — has posted strong recent multi-year returns (reflects Canadian tech performance), but it’s country/sector concentrated and still not in the same league as Bitcoin for total return over a decade. Use XIT if you want Canadian tech exposure (currency, sector tilt). (BlackRock)
FBTC (Fidelity spot BTC ETF) — essentially a vehicle to own Bitcoin inside a Canadian ETF wrapper. It performs like Bitcoin minus fees/track error; but it only exists since late 2021, so you must judge it by Bitcoin’s history rather than FBTC’s short track. (Fidelity Investments Canada)
4) Practical takeaways for you (growth-focused)
If growth is the only metric: historically (last 10 years) Bitcoin was the best performer by a wide margin — but that came with extreme volatility and multi-year drawdowns. No index ETF (QQQ, S&P, XIT) matched Bitcoin’s raw CAGR. (The Case for Bitcoin)
If you want high but more stable growth: QQQ is the closest mainstream ETF that produced strong growth (tech exposure) with much lower realized volatility than BTC — good compromise for long-term growth investors. (FinanceCharts)
If you want BTC exposure in a TFSA (or Canadian account): use a spot BTC ETF (FBTC, BTCX, BTCO, BTCQ) rather than futures products — they hold actual BTC and therefore are the closest way to capture Bitcoin’s price performance inside regulated ETFs. FBTC is one of the low-fee Canadian options. (Fidelity Investments Canada)
5) Sources & where I pulled numbers (most important references)
Bitcoin CAGR & historical charts: Casebitcoin / BTC CAGR charts & historical indices. (The Case for Bitcoin)
6) If you want next steps (I can do any of these now)

BTC vs QQQ vs S&P500 vs XIT — 10-Year Performance, CAGR & Risk-Adjusted Comparison
(reproducible — run the code to fetch live data and recreate charts/tables)
What this piece contains
Quick summary of goals and approach.
The exact Python code (copy/paste) that fetches historical prices, creates a log-scale cumulative returns chart, computes CAGR for 1/3/5/10 years (with exact date ranges), and computes Sharpe ratio and max drawdown for each ticker.
How to interpret results and what to look for.
A short, plain-English verdict about which indices matched Bitcoin historically and how to view performance vs volatility.
1) Summary & approach (quick)
You asked for a side-by-side comparison of Bitcoin (BTC), QQQ (Nasdaq-100 ETF), S&P 500 (SPY as proxy), and XIT (Canadian tech ETF) over the last 10 years — with CAGRs for 1, 3, 5 and 10 years, and risk-adjusted metrics (Sharpe, max drawdown).
Approach:
Use daily price series (close) for each ticker.
Compute cumulative returns and display on log scale so growth rates are visually comparable.
Compute CAGR for exact windows: 1y, 3y, 5y, 10y ending on the chosen analysis date (the script uses today’s date by default; you can set a fixed end date).
Compute Sharpe ratio (annualized) and maximum drawdown for each series.
All code is reproducible and self-contained (uses yfinance, pandas, numpy, matplotlib).
2) The exact Python script (run this locally or ask me to run it)
The script grabs adjusted close prices using yfinance for the tickers:
Bitcoin: BTC-USD
QQQ: QQQ
S&P 500 proxy: SPY
XIT (Canadian tech): XIT.TO (update suffix if your broker uses another form)
End date is today by default (you can set end_date manually — e.g., 2025-11-28 to match a specific snapshot).
The CAGR windows are 1Y / 3Y / 5Y / 10Y computed precisely using the aligned start date (first trading day on or after the exact date n years ago).
The Sharpe ratio uses an annual risk-free rate you set (default 3%). It annualizes returns and volatilities.
Max drawdown is computed on the price series (largest peak-to-trough drop).
4) Interpreting the results (what to expect when you run it)
When you run the script you will get:
A log-scale cumulative chart that shows how $1 invested in each asset grew (log axis makes compound growth lines look like slopes, so higher slope = higher CAGR).
A CAGR table with exact start dates for each window — this tells you annualized growth for each period.
A Risk table showing:
Annualized volatility (higher = more price movement)
Sharpe (higher = more return per unit of risk; if Sharpe is negative or near zero, reward is poor relative to risk)
Max drawdown (a negative number, e.g. −0.65 = −65% worst peak-to-trough)
Typical historical patterns you’re likely to see (once you run it):
Bitcoin usually shows the highest CAGRs over 5–10 years, but also the highest vol & largest max drawdowns (e.g., many samples show drawdowns of 60–80% in bad cycles).
QQQ tends to outperform SPY over 5–10 year periods when tech is strong (QQQ is concentrated in tech + growth names).
SPY (S&P 500) typically shows a solid medium CAGR with lower volatility than BTC and QQQ.
XIT.TO (TSX tech) may show varied performance — it can underperform U.S. tech over the last 10 years due to smaller tech ecosystem in Canada; check the live chart to see exact behaviour.
5) Example of how to read the final table
After running, you might see something like (illustrative only — run script for real numbers):
Instrument
1Y CAGR
3Y CAGR
5Y CAGR

-0.60
These numbers are for illustration only — run the script to get exact, up-to-date numbers and a nice chart.
6) Plain English takeaways (what the results mean)
If growth is your sole criterion: Bitcoin historically often shows the largest compound growth numbers (highest CAGRs). That’s why it’s attractive to growth-seeking investors.
If you care about risk-adjusted returns: compare Sharpe and max drawdown as well as CAGR. Bitcoin’s huge returns often come with very large drawdowns and higher volatility — many investors prefer a lower CAGR that comes with far lower drawdowns (easier to hold through downturns).
QQQ vs SPY: QQQ tends to outperform SPY in tech-led bull markets (i.e., higher CAGR) but also can be more volatile. If you believe in tech’s continued outperformance, QQQ historically rewarded that view.
XIT: Canadian tech tends to lag the U.S. tech giants on scale and innovation; don’t be surprised if XIT underperforms QQQ over long horizons — check the exact numbers after running the script.
7) Next steps I can do for you (pick one)
A. I’ll fetch live prices now and run this script, then return the chart and exact tables (CAGR & risk metrics) for the tickers you named. (I’ll use web sources and include citations — say “run it” and I’ll fetch.)
B. I’ll modify the code to include other ETFs you asked about earlier (e.g., HLAL, FBTC) and produce a broader comparison.
C. I’ll produce a downloadable report (PDF) with charts and the interpretation you can use on your blog.
Which would you like? A, B, or C? (If you want A or B please confirm you want live data fetched now.)
🎯 Part 1 — If I were investing CAD $5,000: SPSK vs SPRE
🔹 Key characteristics & trade-offs
ETF
What works in favor
What to worry about / risk
SPSK (Sukuk-based)
Fixed-income–like behavior → lower volatility; income yield; relatively stable under different equity/real-estate cycles; halal-compliant structure.
Yield is modest; upside (capital gain) limited compared to equity/REIT; currency risk if USD-denominated and you hold in CAD; income/yield dependent on global sukuk market and interest-rate environment.
SPRE (Global REIT)
Offers dividend yield + potential capital upside if real estate markets improve; global geographic diversification via many REITs; historically REITs tend to do well when rates ease or stabilize.
Higher sensitivity to interest rates and global economic cycles; global real estate & currency risk; more volatile — price swings can be larger; income yield + price risk trade-off.
🔮 My choice & reasoning
If I were you and investing $5,000 CADright now, I would choose SPRE — but with the expectation that it’s more speculative than SPSK, and only commit a portion (maybe 70-80%) of the $5,000 to SPRE — leaving remainder (or other cash) aside or used elsewhere.
Why SPRE
The potential return (dividend yield + upside) is greater than SPSK’s conservative income — so for a tranche of capital I’m willing to be somewhat bolder with, the risk/reward balance favors SPRE.
Market environment: if yields remain stable or drop, global REITs often benefit (cap-rate compression, higher property valuations, good for REIT dividends).
More diversified “real-asset + income + growth” exposure compared with a pure sukuk-income strategy.
With caveats / risk mitigation
I’d treat SPRE as a medium-term hold (3–5 years) to ride out rate cycles and global real-estate cycles.
I’d accept potential volatility and possibly dividend cuts if real-estate markets underperform.
I’d avoid overconcentration — keep SPRE as part of a broader diversified portfolio rather than “all-in.”
Alternatively, if my priority were capital preservation and steady income, and I were less tolerant of volatility, then SPSK would be the safer, more conservative pick.
Here’s my take on whether SPRE is a good purchase today — what looks good, what to watch out for, and under what conditions I would buy it. Use this as a thought exercise (or blog-ready summary), not as investment advice. By ChatGPT
✅ What Looks Good Right Now for SPRE
Reasonable yield + income potential: SPRE currently offers a dividend yield in the ballpark of ~ 4.1 %–4.2% per year. (Investing.com)
Global diversified Shariah-compliant REIT exposure: SPRE tracks a global, Shariah-screened REIT index (the S&P Global All Equity REIT Shariah Capped Index), giving you exposure to real estate across markets while respecting Islamic-finance constraints. (Schwab Wall Street)
Relatively modest volatility among REIT ETFs: Since SPRE holds many properties/REITs globally, the idiosyncratic risk of single REITs is diversified away — which makes it potentially less volatile than owning one or two individual property stocks. (Schwab Wall Street)
Potential as a stable income + diversification anchor: For a portfolio that may have equities, sukuk, or growth-oriented assets, SPRE can function as a real-estate anchored income layer — offering diversification from equities/bonds and a hedge against inflation via real estate rents. (SP Funds)
In short: if you believe global real estate income stays stable, and interest rates or macroeconomic conditions remain relatively benign — SPRE offers a mix of yield, diversification, and moderate risk.
⚠️ What to Watch Out For / What Makes SPRE Risky
Interest-rate and macroeconomic sensitivity: REITs (and REIT ETFs) tend to be sensitive to interest rates. If rates rise or are expected to rise, borrowing costs go up for REITs, which can pressure property values and dividend yields. (S&P Global)
Global real estate & currency risk: Because SPRE invests globally, some of its holdings may have exposure to currencies, geopolitics, or property-market cycles different from your home market. This adds complexity compared to purely domestic REITs or bonds.
Moderate performance history: Over the past year, SPRE’s total return (price + dividends) has been negative. (StockAnalysis) That doesn’t mean it can’t recover — but performance hasn’t been stellar recently.
Dependence on rental income and property fundamentals: REITs rely on stable occupancy, healthy tenants, regulation, property maintenance costs, and real estate cycles. Any weakness there (global economic slowdown, real-estate downturn, oversupply) could affect performance. (Facet)
Dividend vs price return trade-off: With REITs, a large portion of return comes from yield rather than capital growth — so expect periodic distributions, but price appreciation may be sluggish, especially in uncertain rate environments.
🎯 My View: Under What Situation SPRE Makes Sense Today
I consider SPRE a reasonable “core+income” holding — especially if you want real-estate exposure with a global and Shariah-compliant tilt. I would consider buying today if:
You expect global economic stability or modest growth, which supports real-estate demand.
You are not overly reliant on capital gains — you value dividend + yield + diversification instead.
You hold a diversified portfolio (equities, maybe sukuk/fixed income, other assets), and want to balance volatility with real-estate-based income.
You’re comfortable with moderate risks (rate sensitivity, global macro, currency) and use a long-term horizon (5–10 years or more).
I’d treat SPRE as a “complementary slice” — not the backbone, but part of a broader asset mix.
✅ What I Would Do (If I Were You)
If I were building or adjusting a portfolio today:
I’d allocate a small-to-moderate percentage to SPRE rather than a large chunk — maybe 5–10% of total portfolio, or a larger share of the “income/fixed-income/alternative-assets” portion if I want yield and diversification.
I’d buy with a long-term mindset: hold through rate cycles, rents, and global real estate cycles, and reinvest dividends.
I’d combine with other assets: global equities, sukuk or bonds (if halal-compliant), maybe some cash, to diversify across asset classes.
I would monitor interest-rate outlook and global property/real-estate trends; if rates rise sharply or the real-estate market cools, I’d consider rebalancing or reducing exposure.
I’d use limit orders and staggered buying, not lump-sum — to avoid buying at potential short-term peaks.
🧮 Final Verdict
Yes — SPRE can be a good purchase today, if your goal is to build a diversified, income-oriented, slightly conservative portfolio rather than chase aggressive growth. It’s not a “get-rich-fast” asset, but a more stable, income-producing, globally diversified real-estate slice.
Is SPSK a Good Buy Today? A Clear Guide for Long-Term Investors: By ChatGPT
The SP Funds Dow Jones Global Sukuk ETF (SPSK) has become one of the most popular halal-compliant fixed-income ETFs available to North American investors. For those seeking stable income, lower volatility than equities, and adherence to Islamic finance principles, SPSK deserves serious consideration. But is today a good time to buy it?
What SPSK Offers
1. Halal-Compliant Fixed-Income Exposure
SPSK invests in global sukuk — asset-backed certificates structured under Islamic finance rules. These securities avoid interest (riba) and are backed by tangible assets, making them suitable for investors seeking Shariah-compliant fixed-income exposure.
2. Lower Volatility Than Equities
Sukuk behave similarly to short–to–intermediate-term bonds. That means smoother price movements and lower drawdowns compared with stock markets, a useful stabilizer in a diversified portfolio.
3. Sustainable Yield
Recent yield levels have hovered in the 3%–4% range depending on market conditions and share class. This makes SPSK an appealing source of steady income while maintaining halal compliance.
4. Moderate Interest-Rate Sensitivity
Sukuk generally exhibit lower duration risk than long-duration government bonds. SPSK tends to react less dramatically to interest-rate shocks, reducing the risk of sharp price swings.
5. Long-Term Track Record & Credible Structure
SPSK follows the Dow Jones Sukuk Index and uses institutional-grade custody for its underlying holdings. For investors who want long-term stability in their fixed-income sleeve, this structure is attractive.
Key Risks to Consider
1. Concentration by Region and Issuer
Most sukuk issuers come from the Gulf region, which means geographic and sector concentration. This limits diversification relative to global bond markets.
2. Lower Liquidity Compared with Major Bond ETFs
The sukuk market is smaller and newer than conventional bond markets. Investors may face wider bid-ask spreads during periods of stress.
3. Currency Exposure
SPSK trades in USD. For Canadian investors, returns will fluctuate based on CAD/USD movements.
4. Regulatory Differences
Sukuk structures vary across jurisdictions. Changes in Islamic-finance regulations or issuer practices may affect valuations.
5. Moderate Yield vs. Alternatives
If interest rates decline sharply, yields across income products may compress, and sukuk returns may become less competitive in relative terms.
Is Today a Good Time to Buy SPSK?
SPSK is a strong long-term income holding — but not a growth asset.
It works well when:
you want stability rather than aggressive returns
you follow halal investing principles
you need a defensive, income-oriented core holding
you want diversification away from pure equities
SPSK is best viewed as a steady, long-term anchor in a diversified portfolio. It is less suitable for short-term speculation or investors expecting high capital appreciation.
How to Use SPSK in a Portfolio
A practical allocation range is:
5%–15% of your fixed-income allocation
paired with diversified equity ETFs for growth
held for income, not frequent trading
monitored periodically for currency and interest-rate effects
The ETF works particularly well in portfolios built around risk management, steady income, and ethical finance principles.
Bottom Line
SPSK can be a strong addition to a long-term, halal-compliant portfolio. It provides stable income, lower volatility, and an ethical alternative to conventional bonds. While it carries concentration and liquidity risks, its income stability and Shariah-compliant structure make it appealing for long-term investors seeking conservative exposure.

TFSA & RRSP Over-Contributions: What Canadians Need to Know (2025 Update)
When planning ahead for retirement or tax-sheltered investing, it’s common to wonder: “Can I contribute early for next year?” or “How much can I go over my limit without penalty?” Here is a clear, simple breakdown of how TFSA and RRSP over-contribution rules actually work in Canada.
1. TFSA Over-Contributions — No “Early” Contributions Allowed
You cannot contribute today for next year’s TFSA room. TFSA contribution room opens January 1st each year, and only then does the new limit become available.
If you contribute early (before Jan 1):
The CRA will treat it as an over-contribution.
Over-contributions are taxed at 1% per month on the excess amount.
The penalty continues until you remove the excess or new room becomes available.
📌 Example: If you try to add your 2026 TFSA amount in November 2025, the CRA will charge a penalty for November and December because that room does not exist yet.
Key TFSA takeaway:
❌ You cannot pre-pay next year’s TFSA room. ✔ The safest move is to wait until January 1st to add the next year’s contribution.
2. RRSP Over-Contributions — A Small Cushion Exists
RRSPs work differently. Unlike the TFSA, the RRSP offers a small “buffer.”
RRSP over-contribution buffer:
You are allowed to over-contribute up to $2,000 in your lifetime without penalty.
However, this $2,000 does NOT generate a tax deduction—it just sits in the account.
If you exceed the $2,000 buffer:
CRA charges a 1% per month penalty on the excess above $2,000.
This penalty stays until the amount is withdrawn or new contribution room absorbs it.
📌 Example: If your contribution room is $10,000 and you contribute $13,000, you are $3,000 over. The first $2,000 is forgiven, but the remaining $1,000 is taxed at 1% per month.
Key RRSP takeaway:
✔ You can go up to $2,000 over your limit without penalties. ❌ You cannot claim a deduction for that $2,000. ✔ Anything beyond that incurs monthly penalties.

Final Thoughts
Both the TFSA and RRSP are powerful tax-sheltered tools, but the rules around contribution timing are strict.
TFSA: No early contributions — wait for January 1st.
RRSP: A small $2,000 buffer exists, but don’t rely on it as a strategy.
Planning ahead is great, just make sure your contribution timing aligns with CRA rules to avoid unnecessary penalties.

How to Run the GNS3 VM Inside Oracle VirtualBox
A Complete Guide
GNS3 becomes far more powerful and efficient when paired with the GNS3 VM. Instead of your host machine running all routers, switches, and appliances, the load shifts into a dedicated virtual machine. While many users rely on VMware, you can run the GNS3 VM just as effectively using Oracle VirtualBox.
This guide walks you through importing the GNS3 VM OVA file, configuring VirtualBox, linking the VM to the GNS3 desktop client, and understanding how the network paths between each component work.
Step 1: Extract the GNS3 VM ZIP File
After downloading the GNS3 VM package for VirtualBox:
Locate the ZIP file (for example, GNS3.VM.2.x.zip).
Extract it using your preferred tool.
Inside the extracted folder, you will find a .ova file — this is the VirtualBox-ready appliance.
What is an OVA file? It’s an “Open Virtualization Appliance,” a ready-to-run virtual machine packaged for import.
Step 2: Open Oracle VirtualBox
Launch VirtualBox.
Go to File → Import Appliance.
This prepares VirtualBox to load the GNS3 VM image.
Step 3: Select the OVA File
Click Choose.
Browse to the extracted folder.
Select the .ova file and click Next.
VirtualBox will show a summary of the machine it is about to import.
Step 4: Adjust the Import Settings
(Highly recommended for performance)
Before completing the import, review the resource allocation:
CPU: Assign at least 2 cores (more if you run complex topologies).
RAM: Minimum 4 GB; 8 GB provides much smoother performance.
Network Adapters: Keep the default NAT + Host-Only configuration.
NAT helps the VM reach the Internet (for updates).
Host-Only ensures reliable communication between your GNS3 GUI and the VM.
MAC Address Policy: Keeping “Generate new MAC addresses for all adapters” can help avoid conflicts.
After reviewing, click Import. VirtualBox will create the VM automatically.
Step 5: Start the GNS3 VM
Select the imported VM.
Click Start.
Allow the VM to boot into the GNS3 VM console (Ubuntu-based).
You should see its IP address and confirmation that the GNS3 backend services are running.
Step 6: Connect GNS3 to the VM
Next, tell your GNS3 desktop application to use the VM instead of running devices locally.
Open GNS3 on your host computer.
Go to Edit → Preferences → GNS3 VM.
Enable “Enable the GNS3 VM”.
Select VirtualBox as the virtualization provider.
Choose the GNS3 VM from the dropdown.
Click Test Settings.
A successful configuration will show a message indicating that the GNS3 VM is detected and running.
How the Host, GNS3 VM, and VirtualBox Communicate
Understanding the communication path helps troubleshoot connectivity and device start-up issues.

How the pieces interact:
1. GNS3 GUI on the Host OS
You design topologies.
Commands and device operations are sent to the VM through the Host-Only network.
2. GNS3 VM running inside VirtualBox
Performs the heavy emulation work.
Handles IOSv, IOSvL2, QEMU images, VPCS, Docker containers, and more.
Reduces CPU/RAM load on your host.
3. VirtualBox Network Adapters
Host-Only Adapter: Used for stable host ⇄ VM communication.
NAT Adapter: Allows the VM to access the internet.
Internal GNS3 Networks: Used by devices inside your topologies to talk to each other.
This architecture ensures that your host machine remains responsive while the VM handles networking workloads.
Final Thoughts
Running the GNS3 VM within Oracle VirtualBox is a powerful solution that avoids the need for VMware products while providing the same performance benefits. Once the VM is imported, configured, and linked with the GNS3 client, you can run large labs with routers, switches, firewalls, and servers — all inside a controlled virtual environment.

Polished: How to Find and Import Cisco Router Images (BIN/IMAGE) Into GNS3 (By ChatGPT)
To use classic Cisco routers such as the 3725 in your GNS3 labs, you’ll need the correct IOS image files. This guide explains where to find them, where to store them, and how to import them properly into GNS3.
Where to Store IOS Images in GNS3
GNS3 expects router images to be placed inside its dedicated IOS directory. On Windows, the default path is:
C:\Users\<your-username>\GNS3\images\IOS
Simply drop your .bin, .image, or extracted IOS files into that folder.
If you received IOS files from another source (e.g., a .zip archive shared through Teams), extract them and place the contents into the images\IOS directory.
Where to Find Cisco Router Images
GNS3 provides a library of appliances and linked documentation. Cisco IOS images themselves are not distributed directly by GNS3, but some resources help guide the process.
Here is a polished, blog-ready version — fully rewritten, original, plagiarism-free, and safe for publishing.
How to Configure VirtualBox Network Adapters for the GNS3 VM (with GNS3 GUI)
Setting up the GNS3 VM correctly inside VirtualBox is essential if you want the GNS3 GUI on your computer to communicate smoothly with the backend VM. This guide walks through the recommended adapter configuration and explains why each setting matters.
Step 1: Open the Network Settings for the GNS3 VM
Launch VirtualBox.
Select GNS3 VM from the list.
Click Settings, then open the Network section.
All adapter configuration will happen here.
Step 2: Configure Adapter 1 (Host-Only Network)
Purpose: Creates a direct link between your host computer and the GNS3 VM. This connection allows the GNS3 GUI to manage devices inside the VM.
Enable Adapter 1.
Set Attached to → Host-Only Adapter.
Choose your default VirtualBox host-only network (commonly vboxnet0).
Leave Promiscuous Mode at Deny.
Keep the default adapter type (Intel PRO/1000 MT Desktop is fine).
This first adapter is the most important one — without it, the GNS3 GUI cannot reach the server process running inside the VM.
Step 3: Configure Adapter 2 (NAT for Internet Access)
Purpose: Allows the GNS3 VM to reach the internet for updates, image downloads, or cloud-related labs.
Enable Adapter 2.
Set Attached to → NAT.
Keep all other settings at their defaults.
This adapter is optional, but recommended if your labs need online access.
Step 4: Start the GNS3 VM
Power on the GNS3 VM.
When it finishes booting, the console will display something like:
GNS3 VM is running
IP: 192.168.56.x
This IP address is assigned from your Host-Only network and is used by the GNS3 GUI to communicate with the VM.
Step 5: Connect the GNS3 GUI to the VM
Open the GNS3 GUI.
Go to Edit → Preferences → GNS3 VM.
Check Enable the GNS3 VM.
Set the virtualization platform to VirtualBox.
Select your GNS3 VM from the list.
Click Test Settings.
You should see a message confirming that the GUI has successfully connected to the VM.
Step 6: Confirm Everything in GNS3
You can verify the setup by:
Adding a device (router, switch, or appliance) to a new project
Starting the device
Watching VirtualBox to see CPU activity inside the GNS3 VM
If the VM is doing the work, you’ve configured everything correctly.
Helpful Tips
Start the GNS3 VM first, then open the GNS3 GUI.
Use the Host-Only adapter for GUI ↔ VM communication.
Add a NAT adapter only if the VM needs internet access.
Avoid installing extra software inside the GNS3 VM unless required — it’s already optimized for GNS3.
