My Weird Prompts

Three million custom GPTs exist, but most collect dust after week one. This episode builds a decision framework for when a custom GPT actually earns its keep. We break down the three levers — system prompts, knowledge base upload, and custom actions — and explain why the car manual is the platonic ideal while the restaurant recommender is the cautionary tale. If you've ever stared at the "Create a...

Can normal people get museum-grade furniture made in China for half the price of local Israeli craftsmen? This episode breaks down the methodical process interior designers use — from factory vetting and prototype inspection to spec sheets and shipping logistics. We cover how to avoid the horror stories, what minimum order quantities really mean, and why the quality of Chinese furniture depends en...

Hannah in Jerusalem wants to know if the organic food she buys for her toddler is actually worth it, especially given that Israel’s pesticide use is unusually high. We dig into the real data on the Dirty Dozen, the Clean Fifteen, and what “organic” actually certifies. This episode breaks down the honest, crop-by-crop answer to one of the most stressful questions in the produce aisle.

A parent named Daniel asks how to pass his love of electronics to his one-year-old son Ezra without exposing him to electrical hazards. This episode explores the practical side of building a safe, low-voltage electronics workspace at home — from the physics of why 3.3V DC is non-lethal to the real risks of small parts and curious mouths. We cover the tools that make modern hobby electronics safer...

You bought a LoRaWAN board promising 15km range, but your parking sensor can't reach two floors up through concrete and rebar. This episode breaks down exactly what's happening when your signal hits a building — regulatory power limits, sub-band fragmentation, spreading factor tradeoffs, and the brutal attenuation numbers for reinforced concrete. We cover why ADR works against you in parking garag...

Daniel finished a week of heavy lifting with rigid Euro boxes, no problem. Then a half-empty cardboard box at the end of the move gave him a lumbar strain. This episode unpacks why — the razor-thin safety margin of the spine, how creep and muscle fatigue quietly erode your protection over hours, and why cardboard boxes are mechanically worse than heavier loads. We also cover what recovery looks li...

Daniel noticed his nocturnal delivery runs through Jerusalem felt quieter at certain hours — but he wanted confidence intervals, not vibes. This episode walks through how to programmatically query Google's Routes API, dump results into BigQuery, and use percentile analysis to find the exact quietest 45-minute window for any route on any day. We cover sampling strategy, API mechanics, the free tier...

What if a walk-in closet could legally function as a border checkpoint? That's the reality of modern bonded warehousing. While most people picture massive portside facilities stacked with shipping containers, e-commerce and air freight are driving demand for bonded spaces as small as 200 square feet. This episode explores the strange legal fiction where goods sit on U.S. soil but haven't legally a...

Most people know Alibaba for AliExpress, but the real story is Alibaba.com—the B2B platform that moves $150-200 billion in goods annually, dwarfing AliExpress’s $60-80 billion. While AliExpress gets all the tariff headlines and app store drama, Alibaba.com operates on 60-70% margins as the stealth engine connecting Chinese factories to global wholesalers. This episode unpacks how the two platforms...

Most hobbyists accidentally choose the wrong battery chemistry every time they click "buy" on Amazon. LiFePO4 — lithium iron phosphate — delivers 2,000 to 5,000 cycles, won't catch fire when overcharged, and sits at a rock-steady 12.8 volts from 90% down to 20% state of charge. This episode breaks down exactly what capacities make sense for 12V and 24V projects, how to connect them using XT60 adap...

When Israel's Attorney General blocked a last-minute 700 million shekel budget amendment for yeshivas during wartime, the money didn't stop because a bank account was frozen. It stopped because an authorization code was never validated in the Bank of Israel's payment system. This episode pulls back the curtain on sovereign finance infrastructure — the Single Treasury Account, real-time gross settl...

What if the best phone isn't a phone at all? This episode explores a radical build: stacking a standalone 5G hotspot, a mid-range Android phone, and a high-capacity battery into a single 3D-printed brick. We break down the antenna physics that make external antennas demolish internal phone radios, the Wi-Fi calling architecture that makes the whole thing work, and why this absurd-looking camcorder...

A listener in Jerusalem watches a man buy high-strength beer every morning, shaking so badly he can barely hand over coins. His father died of alcoholism. Now he’s asking: why can a corner store legally fuel this cycle, and how does the human body survive decades of such drinking? We trace the legal gap between bars and off-premises retailers, the economics of cheap malt liquor, and the physiology...

When Daniel's home server suffered a kernel panic, ChatGPT diagnosed the problem perfectly — missing kernel modules, GRUB errors, the whole works. The repair worked, but it took hours because every single command had to be read off a phone screen and typed into a headless machine in a closet. This episode maps the three approaches to solving that bottleneck: cloud CLI tools with API key auth (like...

Machine translation has gotten so fluent we've stopped being suspicious of it. But that fluency masks a dangerous problem: when AI translates technical documents like RFQs and specs, errors get camouflaged. A study found 30% meaning loss in B2B technical text — and those weren't awkward translations, they were smooth sentences with wrong specs. This episode breaks down universal rules for writing...

Millions of small business websites display phone numbers as plain text, forcing visitors to manually copy and dial. Each extra step loses 20-30% of potential callers. The fix is a tiny HTML attribute combining the tel URI scheme with the E.164 international numbering standard. In this episode, we break down why the leading zero gets dropped, how to format numbers for global compatibility, and why...

Tired of ISPs saying "looks fine on our end"? This episode covers four open-source tools you can run on your own hardware to track actual latency, jitter, and throughput over weeks and months. From the powerful TIG stack (Telegraf, InfluxDB, Grafana) to the OPNsense-native SmokePing plugin, we walk through what to install, how to configure it, and how to use long-term data to hold your provider ac...

The Harmonized System promises a universal language for global trade — but the reality is far messier. In this episode, we break down why the same product can be classified differently across borders, how a frozen french fry importer overpaid duties for years and still faced penalties, and where customs brokers actually earn their keep. If you're navigating B2B importing, understanding the General...

Freight volume consolidation sounds simple — just divide cubic volume by pallet size, right? Wrong. The moment you introduce multiple SKUs with different dimensions, you're solving an NP-hard three-dimensional bin-packing problem. And the tool you pick makes an optimization decision on your behalf, often without telling you. We break down three very different approaches: PalletStacking's greedy al...

When Daniel needed two pallets of industrial storage boxes delivered to Jerusalem, he found two paths on Alibaba — DAP (a customs nightmare) and DDP (a false promise). The real solution? A procurement resourcing agent: a local intermediary who verifies suppliers, negotiates MOQs, consolidates orders, and handles door-to-door delivery with a bonded broker. This episode unpacks why the agent model i...

When a DAP quote comes in ten percent cheaper than DDP, are you actually saving money—or buying yourself a part-time job as an importer? This episode breaks down the real cost difference between Delivered at Place and Delivered Duty Paid. We walk through bond requirements, broker fees, exam risks, and the accounting illusion that makes DAP look cheaper than it is. If you're buying B2B under either...

DDP (Delivered Duty Paid) sounds like a white-glove service, but it's actually freight delivery with customs included. If you give a residential address, you'll face liftgate fees, undeliverable marks, and storage charges. This episode explains how to find third-party fulfillment centers that work within Cainiao's logistics network — letting you receive pallets at a loading dock for $5-15 each, wi...

When someone you're close to habitually badmouths a family member you know is a good person, every response feels wrong. Stay silent and you're complicit. Defend the target and you become the enemy. Try to reason and you're accused of naivety. This episode breaks down why this communication trap is so hard to escape — rooted in psychological mechanisms like splitting and triangulation — and offers...

When Daniel tried to buy 40 industrial Euroboxes, he found a $0.50 factory price on Alibaba and a $30 local price — a 6,000% markup. In this episode, we crack open that $30 box to trace every layer of the supply chain: manufacturing, ocean freight, customs, distribution, pallet-breaking, and retail. What looks like price gouging turns out to be the arithmetic of making a 40-cent object available t...

When telling a difficult story could destroy your life, how do you share it safely? This episode explores Daniel's proposal for an AI-powered obfuscation agent that goes beyond simple find-and-replace. We break down the quasi-identifier problem, the difference between redaction and true obfuscation, and how attention mechanisms enable context-aware entity recognition. From therapeutic disclosures...
