Warqa stamps each PDF and image with the downloader's email to trace leaks

0
·2 views

Warqa, a contract management platform for Saudi companies, adds the downloader's email to every PDF and image at download time. The original file remains untouched in storage, and only a temporary stamped copy is sent. The stamp is a faint, repeated diagonal grid so it stays readable but is hard to crop out. Each copy also gets a unique tracking ID recorded in the file metadata and the activity log. If stamping fails, the error is reported and the file is still delivered without blocking the user.

Developer Automates Daily Google Calendar Screenshots Using Playwright, rclone and systemd

A developer built a workflow on Ubuntu to automatically capture a rolling seven-day view of Google Calendar as an image, rather than exporting event data through an API. The pipeline uses Python with Playwright to drive a headless Google Chrome browser, saves dated PNG files locally, and uploads them to Google Drive via rclone, all scheduled by a systemd user timer. The author found authentication the most challenging part, as Google rejected sign-in from Playwright's bundled Chromium, so a dedicated persistent Chrome profile was used instead. Sessions were reused successfully by launching both the manual sign-in and headless runs with the same Linux password-storage mode. The original workflow was tested on Ubuntu 22.04 with Playwright 1.48.0, while the public repository's generalized version has not been independently tested with a live account.

Developers Share Lessons From Building Fail-Closed Verification Tools for AI Agents

The author reports building two small open-source verification tools for the emerging AI agent economy, which share a rule: an unverifiable result should never be reported as clean. Al-Muqarin checks claims against signed, dated snapshots of public sanctions lists and returns a not-measured result when a list is missing, stale, or below a minimum version. agent-receipt-verify checks x402/EIP-712 payment receipts and reports incomplete ones as failures rather than passing them. The team tests its tools by planting deliberate bugs and confirming that tests catch each one, with Al-Muqarin catching all 548 planted faults. The authors acknowledge that other services already sign sanctions-screening results and that their tools have no paying users yet. They also disclose an unresolved weakness in a separate prototype, where the verifier identity field is free text and can be exploited.

Teks melingkar dibuat ulang dengan Python dan fontTools, membandingkan jarak antarhuruf

Tata letak teks melingkar yang terlihat rumit sebenarnya memposisikan setiap huruf di sepanjang busur dan memutarnya menghadap ke luar. Penulis menunjukkan cara meniru fitur Type on a Path di aplikasi desktop osFoundry dengan Python, menggunakan fontTools, numpy, dan Pillow. Dengan skrip tersebut, stempel KUMO COFFEE ROASTERS dibuat di atas lingkaran berdiameter 450,6 px. Hasil pengukuran memperlihatkan bahwa memutar huruf dengan sudut sama menghasilkan jarak tidak rata, dengan celah negatif di sekitar huruf lebar dan spasi antarkata yang menggelembung. Penulis juga membahas posisi teks rata tengah pada path tertutup bergantung pada titik awal.

Why multi-file C++ programs fail in online compilers and how to fix them

Many online C++ compilers accept only a single editor file, so a program split into a header and source file fails with a missing-header error. Pasting only the header does not help, because the member function definitions live in the .cpp file, which then triggers linker errors. The article explains that the program must compile and link all source files together. It shows an example Student class split across header and source files, and notes rules such as exact filename matching, folder support, and file limits on one platform. It also describes how to submit multiple files through an API using Python.
