OMRFlow

Wed, 23 Sep 2026 00:00:00 +0000

Motivation

Marking multiple-choice examinations by hand is slow, and the commercial OMR systems that automate it are closed, licence-bound and generally expect the answer sheets to be uploaded somewhere. A department that wants to keep student scripts on its own machines needs something it can run locally and inspect.

What it does

OMRFlow covers the sequence end to end: a template designer defines the registration markers and bubble grid for a sheet; scans are geometrically normalised for rotation, translation, scale, skew and perspective; recognition reports what it found, including blanks, multiple marks and uncertain reads rather than silently guessing; batches are processed across multiple cores and can resume after an interruption; a human resolves the uncertain cases, with an audit trail of every correction; attendance is reconciled; per-set answer keys are applied and verified; and reports are generated while preserving the custom formatting of the destination workbook.

Processing is local. The software is MIT-licensed and the source is on GitHub.

Status

Alpha. The current installable release is 0.1.0-alpha.1, published for evaluation and testing. The repository states that real-data qualification is not complete and that generated results should be independently verified before operational use. The repository is the place to check the current qualification status before relying on it for an examination.

Scholar Profile Exporter

Sat, 24 Jan 2026 00:00:00 +0000

Motivation

Keeping per-article citation counts in a CV or publication list is tedious to do by hand. The Publish or Perish desktop tool used to fill that role, but Google Scholar increasingly requires a signed-in session or a CAPTCHA, which that tool does not handle.

What it does

The script runs as a TamperMonkey userscript on top of a loaded Google Scholar profile page — so it works within an ordinary signed-in browser session — and exports the profile in a Publish-or-Perish-style CSV, together with BibTeX links. That CSV is the input format an existing set of scripts already expects, so the downstream publication-list and BibTeX update workflow is unchanged.

Status

Active. Source is on GitHub; it requires the TamperMonkey browser extension.

Pi Web Kiosk

Wed, 24 Sep 2025 00:00:00 +0000

Motivation

A lobby display has to keep showing something sensible when nobody is watching it: when the network drops, when the site it mirrors is down, when the machine has been running for a fortnight, and outside the hours anyone is there to see it. Doing that reliably on a Raspberry Pi is mostly a matter of configuration rather than code, so the whole system is driven from a JSON file.

What it does

Two Chromium kiosk windows are placed across an extended dual-display desktop. Content is mirrored to an offline cache at setup, and the kiosk falls back to that cache automatically when the network or the live site is unavailable, switching back to the live URL once connectivity returns. A hard refresh runs every few hours, the machine reboots daily at a configurable time, and display hours, active weekdays and holiday handling are all set in the same configuration file. Startup and recovery are handled by systemd.

Status

Active, and in use: the README records that the kiosk runs the information display in the main lobby of the Department of Electrical and Electronic Engineering, BUET. MIT-licensed, with the setup script and systemd unit in the repository.

CTAdmin

Sun, 11 May 2025 00:00:00 +0000

Motivation

Seating students in roll-number order during a class test discourages groups of students who might otherwise sit together and collaborate. Producing that seating chart by hand in PowerPoint or Excel before every test is slow and has to be repeated for each room and each cohort.

What it does

CTAdmin generates the seat plan from a roll-number list and provides the timing function needed while the test is running, so both parts of running a class test are handled by one tool rather than a spreadsheet plus the operating system’s timer app.

Status

Active. Source and documentation are on GitHub.
