Pharo Smalltalk Runs in the Browser via WebAssembly

·1 views

A project has been shared on Hacker News showing the Pharo programming environment running directly inside a web browser. The implementation uses WebAssembly to execute Pharo's virtual machine client-side. The demo is hosted as a web page on a personal GitHub Pages site. The post drew modest attention, with 4 points and no comments at the time of listing. The source material provides limited detail beyond the link itself.

Outlook Search Missing Emails? Check the Windows Search Index First

Help desk staff often find that Outlook search fails to show emails the user is sure exist, and the usual first step of rebuilding the Outlook profile may be unnecessary. In classic Outlook for Windows, search depends on the Windows Search index, so a paused, stalled, or corrupted index can hide messages that are still in the mailbox. Technicians can check indexing progress under File > Options > Search > Indexing Options, and confirm the WSearch service is running via PowerShell. If the problem persists, rebuilding the index from the Advanced settings is recommended, though it can take hours on large mailboxes. Finally, verifying the cached mail download range and comparing results with Outlook on the web can reveal whether the issue is local.

AML Analysts Lose Capacity When Case Retrieval Is Manual

A DEV Community post frames slow manual retrieval of case information as a major defect in anti-money laundering operations. It argues that analysts lose substantial capacity when they must gather history, links, and background themselves before reviewing an alert. The author describes a common workaround of asking a senior colleague, which fails once that person leaves the organisation. The proposed fix is to retrieve relevant sources before an analyst opens a case, present them transparently, and keep human decision-making in charge. The piece characterises this as a workflow problem rather than a model-accuracy issue.

Acceptance testing a small salon app with fake data across 61 scenarios

Before a real salon used the app, a separate AI session acted as the owner on a test computer with fake data, running 61 scenarios over four rounds. The first round uncovered 19 defects, some serious, which were all fixed, and later rounds came back clean. The scenarios targeted difficult cases such as forced password changes, lockouts after wrong passwords, messy Italian-language spreadsheets, duplicate imports, wrong time zones, data isolation between salons, large customer lists, unreliable networks, and mobile and keyboard use. The report also noted what could not be verified, such as the real booking-software export and WhatsApp messages, and left these for a supervised first session with the owner. The author now runs such an acceptance round before handing over any app, since it catches a different kind of mistake than automated tests do.

How Solana Liquidity Pools Set Prices and Why Depth Affects Swaps

On Solana, swaps can be executed against on-chain liquidity pools holding reserves of two tokens rather than through a traditional order book. These pools are governed by automated market maker programs, with constant-product designs keeping the product of reserves fixed so that prices adjust automatically after each trade. Liquidity providers supply both tokens, earn a share of swap fees, and face impermanent loss when external prices diverge. Price impact depends largely on pool depth, meaning the same trade can move prices far more in a small pool than in a large one. Solana also hosts concentrated, dynamic, and professional market maker designs, and routing software often splits trades across several pools to reduce costs.
