Even in blue states, nonreligious tech entrepreneurs and CEOs are increasingly asking for “traditional” and “conservative” women, matchmakers tell WIRED.

its like i can write code of simple problems but i finds myself not so easy when it comes to the program like terminal games and i feels like i am lagging the "right thinking" before writing any code. well the thing is i completed like 22 projects from the book big book of small python projects and i am still writing codes like this https://paste.pythondiscord.com/HGNA i feels like i know python but lacks in thinking on how to approach a problem and making it run properly. and i feels like if i keep practising like this i wouldn't get any close to writing code more effectively any sooner unless i have someone to tell me the right way or i learns it from a tutor or a course or a book on how to approach and think of a problem, cuz if i were to just practise and do it on my own i would be doing hit and trials and it might take me much longer compared to if i m being taught on how to write it better. so how should i go further on now ? i just want to ask how to think when we were given a problem say we were given to make a terminal program and i always just confuse like yeah i can make it work but i still feels like i need to learn to write it neatly. i can make small programs but i want to learn how to make complicated programs or think/design beforehand on making these programs tldr; asking if it will be good to read some "tips" from somewhere or watch any lectures on thinking properly instead of just practising which i think might take "more" time for e.g. will it be beneficial to read books like "think like a progrmmer" by al sweigart ? instead of just practising and finding the neat ways on my own ? submitted by /u/TreacleFlaky2283 [link] [留言]

OpenAI introduces three Academy courses that help people build practical AI skills, create repeatable workflows, and apply agents in everyday work.

There we were, a regular murderers’ row of librarians. Little Jo. Eustace. And me. Turning around in the nave of our library to greet the sound of footsteps, pistols leveled in case whoever was coming in didn’t respect sanctuary. Little Jo had a stack of books under one arm. Eustace was holding the screwdriver she’d…

Saturday morning. I opened Twitter and saw a tweet about the Laravel-Lang packages being compromised. My first reaction was simple: "I don't use that package." Then I opened composer.json on a project I work on and found this in require-dev : "laravel-lang/lang" : "^14.8" , "laravel-lang/publisher" : "^16.8" , That changed things. What Actually Happened The attack used laravel-lang packages as the distribution channel. And the sneaky part: the main repository branch looked completely clean. No suspicious commits, no new code. The malicious payload was pushed via git tags on forks . Most developers would not notice anything. Just a routine composer update , same as always. Once installed, the payload executed at autoload time . That means every php artisan command, queue worker, or web request running that codebase triggered the malware the moment PHP hit require_once __DIR__.'/../vendor/autoload.php' in public/index.php . Silently. No error, no red screen, nothing. The malware was a credential stealer. It searched the machine for: .env files from Laravel projects AWS access keys and session tokens SSH private keys GitHub CLI tokens NPM tokens Infrastructure secrets This is not a SQL injection that messes with your database rows. This is a key stealer that runs on your machine and takes everything it finds. Aikido Security caught it and reported it to Packagist. Packagist removed the affected versions. But if you ran composer update during that window, you were exposed. Why Supply Chain Attacks Are Different Classic Laravel security talks about SQL injection, XSS, CSRF. Those are attacks that come from outside users sending malicious input to your application. Supply chain attacks come from inside your own development process. The attacker does not need to find a vulnerability in your code. They need to compromise one developer account at one package maintainer. Every project depending on that package is now exposed. With AI tools, these attacks are getting more soph

Pada series sebelumnya, kita sudah melakukan instalasi nix di VirtualBox dan setup SSH agar dapat diakses diluar VirtualBox. Sebelum kita lanjut untuk melakukan konfigurasi system lagi, kita butuh mengetahui bagaimana syntax dalam menulis program Nix dan di artikel ini kita akan mempelajari dasar syntax-nya. Nix Language Nix adalah purely functional language yang lazy-evaluated , digunakan untuk mengkonfigurasi Nix package manager dan NixOS. Karakteristik utama: Purely functional : sebuah function hanya bisa mengembalikan nilai berdasarkan inputnya, tidak bisa mengubah variabel di luar scope-nya (no side effects), dan tidak ada variabel yang bisa diubah setelah didefinisikan (no mutation). Kalau kamu familiar dengan const di beberapa bahasa pemrograman, semua variabel di Nix berperilaku seperti itu. Lazy evaluation : Nix tidak menghitung nilai suatu ekspresi sampai nilai itu benar-benar dibutuhkan. Ini artinya kamu bisa mendefinisikan ribuan package di nixpkgs tanpa semuanya dievaluasi sekaligus. Hanya yang kamu gunakan saja yang akan diproses. Semua adalah expression : tidak ada statement di Nix, setiap baris kode selalu menghasilkan sebuah nilai. if/else bukan statement seperti di bahasa pemrograman pada umumnya, melainkan expression yang harus mengembalikan nilai dari kedua cabangnya. Tidak ada loops : karena variabel tidak bisa diubah, loop seperti for atau while tidak ada artinya di Nix. Sebagai gantinya, kamu menggunakan fungsi seperti map dan filter , atau rekursi untuk mengolah kumpulan data. 1. Basic Data Type Konsep JavaScript Nix String "hello" "hello" Number 42 , 3.14 42 , 3.14 Boolean true , false true , false Null null null List [1, 2, 3] [ 1 2 3 ] Object { a: 1 } { a = 1; } ⚠️ Perbedaan Penting List di Nix menggunakan spasi sebagai pemisah, bukan koma Attribute set menggunakan = bukan : , dan setiap entry diakhiri dengan ; Nix let name = "Alice" ; age = 30 ; scores = [ 10 20 30 ]; person = { name = "Bob" ; age = 25 ; }; in person Javascript const name

When code becomes cheaper, what still makes an engineer valuable? Recently, while writing my cover letter for remote roles and Upwork projects, I asked myself a very direct question: Why should a remote team or client choose me, especially in the AI era? I do not think the answer should be: “Because I am the strongest engineer technically.” That is not how I want to position myself. What I want to become is this: A backend engineer who can turn unclear business problems into reliable, maintainable systems. AI is making implementation faster. It can generate code, explain technologies, and provide alternatives. At the same time, remote work and platforms like Upwork make competition more global. We are not only competing with engineers nearby, but also with engineers from everywhere. If the only question is “Who knows more frameworks, patterns, or tools?”, many ordinary engineers may feel hopeless. But I believe there is another path. In real systems, code is only part of the work. Someone still needs to understand the business workflow. Someone still needs to define what “correct” means. Someone still needs to identify risks, edge cases, performance concerns, and reliability boundaries. My usual way of working starts from these questions: What is the real requirement? What does correctness mean in this workflow? What data must stay consistent? What edge cases could break the process? What performance or reliability signals should be protected? Where should the module boundary be? Who should orchestrate the main flow, and who should act as collaborators? This “orchestrator + collaborators” thinking helps me keep the main business process clear. The orchestrator owns the workflow. The collaborators handle specific responsibilities such as validation, translation, persistence, messaging, or external integration. I also use AI in this process, but not only to generate code. I use it to challenge my assumptions, explore alternatives, find missing cases, improve naming, r

A few days ago I finished benchmarking something I've been building - a cache-aware, stable, histogram-based sorting algorithm I'm calling BusSort . The results surprised even me. At 100 million elements, it runs ~2x faster than Java's Dual-Pivot Quicksort on random data - while being stable . Dual-Pivot QS is not. The Problem With Quicksort at Scale Quicksort-based algorithms partition elements with random writes across the entire array. At large scales this causes cache thrashing - elements are being written to memory locations all over the place, constantly missing L1 and L2 cache. The larger the array, the worse it gets. The Core Idea Instead of scattering elements globally, BusSort processes data in L1 cache-sized chunks - 4096 integers (~16KB). For each chunk, it does 4 passes: PASS 1 - Scan left-to-right, compute bucket for each element, build a local histogram PASS 2 - Compute local prefix sums (bucket positions within the chunk) PASS 3 - Scatter into a local grouped buffer - because this buffer is L1-sized, all random writes stay in cache ✅ PASS 4 - Copy each bucket's portion to its correct global position With 128-way splitting , recursion depth stays at just ~4 levels even for 100M elements. Base case: Insertion Sort for ≤ 1024 elements. On the benchmark machine (i5-1135G7, 48KB L1 data cache): 4096 × 3 × 4 bytes = 49,152 bytes ≈ 48KB The three working arrays fit exactly in L1. Not a coincidence. Benchmark Results Tested against Arrays.sort(int[]) - Java's Dual-Pivot Quicksort . n = 100,000,000 | Java 17 | i5-1135G7 @ 2.40GHz Input Type BusSort Dual-Pivot QS Ratio Random 3991ms 8604ms ~2x Sorted 57ms 104ms ~2x Reverse 280ms 166ms 0.6x Nearly Sorted 2452ms 2789ms ~1.1x Duplicates 712ms 2242ms ~2.4x Few Duplicates 1295ms 3185ms ~2.3x All Same 51ms 32ms 0.6x Clustered 1419ms 2242ms ~1.6x Consistently faster on most input types. Stable. Zero comparison overhead. The two losses (Reverse, All Same) are where Dual-Pivot QS has structural advantages - run detecti

I used to hear the pitch for context compression and think: sure, makes sense. Smaller prompts. Lower latency. Lower cost. Same output quality. Then I watched an agent blow a perfectly good debugging session because one field name disappeared from compressed memory. That changed my opinion fast. Three hours into a Claude Code run, the agent made the wrong API call with full confidence. The plan looked coherent. The reasoning looked clean. The summary of prior steps sounded smart. It was also missing the one detail that mattered: a field name from an earlier error log. The agent had already seen the bug. It had already “understood” the bug. But the compressed version of history dropped the exact detail it needed to avoid repeating it. That’s the real failure mode. Not “compression loses words.” Compression loses the one fact your agent needs later, after it has already committed to the wrong action. While researching this, I found a thread on r/openclaw about using Headroom with OpenClaw: https://reddit.com/r/openclaw/comments/1u3j5xs/anyone_using_headroom_with_openclaw/ That thread gets at the real tension: compression is useful, but only if you treat it as a reversible optimization, not a memory wipe with better branding. The bug pattern nobody talks about Here’s the pattern I keep seeing in long-running agents: The agent collects a lot of noisy context. The team compresses it to save tokens. The summary preserves the broad story. The summary drops one edge-case fact. Two hours later, that fact becomes the only thing that matters. The agent confidently does the wrong thing. This is why “same answers, fewer tokens” is not a serious reliability claim for agent workflows. It might be true for some short chat tasks. It is absolutely not something I’d assume for: n8n agents Make scenarios Zapier AI steps OpenClaw sessions Claude Code runs custom OpenAI-compatible agent loops multi-step debugging or incident workflows In those systems, exact details matter more than eleg

なぜ“特別な決済システム”の話は危険なのか？ 近年、SNSやメッセージアプリを通じて、「特別なPOS端末」や「秘密の決済システム」に関する話を目にすることがあります。 「通常の銀行システムを経由しない」 「オフラインでも大金を受け取れる」 「特別なカードと専用POSがあれば送金できる」 こうした説明は一見すると高度な金融技術のように聞こえます。 しかし、実際の決済システムを理解すると、多くの主張が現実的ではないことが分かります。 まず、POS端末とは何か？ POS（Point of Sale）端末は、店舗でクレジットカードやデビットカードによる支払いを処理するための装置です。 一般的な決済は以下のような流れで行われます。 顧客 ↓ POS端末 ↓ 加盟店契約銀行 ↓ カードブランド ↓ カード発行銀行 ↓ 承認または拒否 重要なのは、最終的な資金の確認を行うのはカード発行銀行であるという点です。 POS端末そのものが資金を生み出すことはありません。 「オフライン決済だから大丈夫」は本当か？ 一部の詐欺では、 「この端末はオフラインで動作する」 という説明が行われます。 確かに、現実の決済システムにはオフライン処理が存在します。 しかし、それは通信障害時の一時的な仕組みであり、最終的には銀行側との照合が行われます。 つまり、 オフライン処理 ≠ 資金の創造 です。 銀行が承認していない資金は、後の精算時に拒否される可能性があります。 なぜ人は信じてしまうのか？ 理由は単純です。 専門用語が多いからです。 例えば、 決済ネットワーク 国際ブランド オフライン認証 ISO規格 特殊プロトコル こうした言葉が並ぶと、本物らしく見えます。 しかし、本当に重要なのは技術用語ではありません。 重要なのは、 「お金はどこから来るのか？」 という一点です。 詐欺を見抜くための3つの質問 1. お金の出所はどこか？ 利益や送金の原資を説明できない場合は要注意です。 2. 誰が監督しているのか？ 銀行、決済事業者、規制当局など、責任主体が明確か確認しましょう。 3. 第三者による検証は可能か？ 説明が内部関係者の証言だけに依存している場合は危険です。 テクノロジーと金融リテラシー 新しい技術は私たちの生活を便利にします。 しかし、技術的な言葉が使われているからといって、その仕組みが正しいとは限りません。 本当に優れた金融サービスほど、 透明性が高い 説明が分かりやすい リスクが明示されている という特徴があります。 逆に、 「秘密」 「特別」 「限定」 「誰にも教えないでほしい」 といった言葉が頻繁に出てくる場合は、一度立ち止まって考えるべきです。 まとめ 金融詐欺の多くは、技術ではなく心理を利用します。 人々はお金を失うから騙されるのではありません。 「理解したつもりになる」から騙されるのです。 だからこそ、最も重要な防御策は、 「そのお金はどこから来るのか？」 というシンプルな質問を忘れないことです。 金融の世界に魔法はありません。 あるのは、透明な仕組みと説明可能な資金の流れだけです。

Every developer I know has built something for themselves. A productivity tool. A habit tracker. A personal finance app. An AI that makes them smarter, faster, calmer. I did the same thing for 2 years. Then I had a conversation with someone close to me that I completely mishandled — and I realised no amount of personal productivity tools would have helped me there. The problem wasn't me, individually. The problem was the space between us. So I started asking a weird question Why has all of AI been built for individuals? Copilot helps you code faster. ChatGPT makes you smarter. Notion AI organises your thoughts. Calm helps you sleep better. Not one of them is built for what happens when two people try to understand each other. That's a massive gap. And it's one I couldn't stop thinking about. What I built Mendle — an AI-powered Relationship Intelligence platform. Not a therapy app. Not a chatbot companion. Not another journaling tool with an AI skin on top. The core idea is **shared emotional memory. Most relationship apps are built around one person's perspective. You log your feelings. You get insights. Your partner is an afterthought in the architecture. Mendle is different at the data model level. Both people contribute. Both people benefit. The AI builds an understanding of the relationship not just an individual. Over time it surfaces patterns. Communication loops. Emotional triggers. The things you keep missing because you're too close to them. The technical challenge that surprised me Building AI for two people is fundamentally harder than building it for one. Single-user AI: one context window, one set of preferences, one voice to understand. Relationship AI: two different communication styles, two different emotional vocabularies, shared history that neither person has complete visibility into, and privacy boundaries that have to be respected even between partners. The shared memory architecture was the hardest part to get right. How do you build something

Shifting from traditional application testing to serverless TypeScript engineering is all about shifting your perspective: you stop testing a running server, and you start testing how your function responds to events and SDK states. Here is a simple, practical example for each testing, using modern AWS SDK v3 syntax. 1. Unit Testing: Jest + Mock Payloads & SDK Client Mocking In unit tests, you don't call real AWS services. You pass a simulated API Gateway event to your handler, and you mock the AWS SDK so it returns predictable data instead of hitting live infrastructure. The Code Under Test ( src/handler.ts ) import { APIGatewayProxyEvent , APIGatewayProxyResult } from ' aws-lambda ' ; import { DynamoDBClient } from ' @aws-sdk/client-dynamodb ' ; import { DynamoDBDocumentClient , GetCommand } from ' @aws-sdk/lib-dynamodb ' ; const ddbClient = new DynamoDBClient ({}); const docClient = DynamoDBDocumentClient . from ( ddbClient ); export const handler = async ( event : APIGatewayProxyEvent ): Promise < APIGatewayProxyResult > => { const userId = event . pathParameters ?. id ; if ( ! userId ) { return { statusCode : 400 , body : JSON . stringify ({ message : ' Missing ID ' }) }; } // Fetch from DynamoDB const result = await docClient . send ( new GetCommand ({ TableName : process . env . USERS_TABLE , Key : { id : userId } })); if ( ! result . Item ) { return { statusCode : 404 , body : JSON . stringify ({ message : ' User not found ' }) }; } return { statusCode : 200 , body : JSON . stringify ( result . Item ), }; }; The Jest Unit Test ( tests/unit.test.ts ) Instead of the legacy aws-sdk-mock , the modern standard for AWS SDK v3 is aws-sdk-client-mock . import { handler } from ' ../src/handler ' ; import { APIGatewayProxyEvent } from ' aws-lambda ' ; import { mockClient } from ' aws-sdk-client-mock ' ; import { DynamoDBDocumentClient , GetCommand } from ' @aws-sdk/lib-dynamodb ' ; const ddbMock = mockClient ( DynamoDBDocumentClient ); describe ( ' Lambda Handler Unit

The company has set aside an unusually high number of shares for retail investors. Still, experts say, you’re just getting the crumbs.

David Stein shares how to rethink large-scale architectural migrations using AI. He discusses ServiceTitan's "assembly line" pattern, explaining how decomposing legacy codebase refactoring into standardized tasks can achieve massive parallelization. He highlights the critical role of programmatically rigid validation loops to eliminate LLM hallucinations and accelerate engineering agility. By David Stein
