How many hours do you lose hunting through old test papers for that one specific exam problem? As a university lecturer, this drove me crazy. So I built Qubase to fix it. It parses your worksheets into an organized, searchable question bank. Never dig through files again. Qubase.ai #professors

Every semester, exam prep meant digging through 50+ messy PDF worksheets to find the right questions. I built Qubase with fellow educators. Its AI turns old worksheets into a searchable, categorized question bank instantly. Save hours this term: qubase.ai

Every exam cycle, I use entire weekends retyping equations and checking if I repeated last year's problems. It drove me crazy. I ended up creating an app to streamline the process. It parses PDFs into organized question data: qubase.ai

Endless PDF folders. Zero searchability. As a lecturer, organizing my worksheet assets was my most frustrating admin task. So I built Qubase. It instantly transforms raw course worksheets into an organized question database, saving hours on exam prep: www.qubase.ai

Does sharing exam prep with colleagues still mean digging through messy folders named Midterm_2022_FINAL_v2? I got tired of opening 20 files just to find one question. So I built Qubase. It turns PDFs into a shared, searchable question database: qubase.ai

When a mid term test was over two weeks ago, and the scores and suggested solutions have been released, a student send you a medical certificate asking for make up. That ruins your day…..

As an educator, I hate sharing past exam papers. Colleagues have to comb through dozens of files to find the right questions to use. That’s why I create Qubase. Our AI indexes every question into an accessible database. Find and reuse materials seamlessly: qubase.ai

Every exam cycle, I use entire weekends retyping equations and checking if I repeated last year's problems. It drove me crazy. I ended up creating an app to streamline the process. It parses PDFs into organized question database: qubase.ai

Why are professors still manually sorting test questions in 2025? Designed by a fellow university teacher, it organizes worksheets into a smart question repository that you can search, sort, and compare questions. See for yourself: qubase.ai

Writing finals shouldn't mean drowning in 40 different PDF files. Qubase is built by educators to convert old worksheets into a dynamic, searchable question bank instantly. Track usage, spot duplicates, and build exams faster. Try it out: www.qubase.ai

Every semester, the same dread: did I accidentally reuse this exact exam question last year? Tracking question frequency across messy folders is a headache. Qubase turns your old worksheets into an intelligent question database. It tracks reuse frequency: qubase.ai

Accidentally reused the exact same midterm question two semesters in a row? We've all been there. Built by educators for higher ed, Qubase parses your legacy worksheets into a smart database that tracks question history and prevents duplicate testing: www.qubase.ai

"Did I use this exact question on last term's final?" If you teach in higher ed, you know that fear of using the same questions in an assessment. I built an app to fix this. It scans your worksheets and tracks question usage across semesters. Build balanced tests effortlessly. www.qubase.ai

Midterms are coming, and you're digging through 5 years of folders just to build one exam paper. Stop manually copying equations and tables. Qubase is built to end this nightmare. Import your worksheet assets, and our AI instantly creates a searchable question database in one place. www.qubase.ai

Every educator’s nightmare: Spending hours looking for that one test question you wrote 2 years ago, only to give up and retype it from scratch. 🫠 I have built qubase.ai that helps automating the task. Ask me anything here.

I’m still convinced there has to be a smarter way to manage grades than clicking through 100 sub-menus in Moodle. It feels like we have AI tools everywhere else, but our main teaching hub does not move fast enough to catch-up. Any suggestion on how Moodle can be automated by agents?

Fellow lectures and professors: There is nothing more exhausting than spending hours on low-value, mechanical tasks when we have the technology to automate them in minutes. How much of your weekly workload feels like busywork, and what's the one thing you wish you could eliminate tomorrow?

In one of my courses, it has open book tests. Previously I allowed them to use iPad or phone for checking notes. Almost all of them did not print out slides: It saved a lot of paper. Now, checking device is banned because of the AI thing, they have to print notes, a big step backwards…

The Math major I am teaching has a one unit course on programming. Everyone told me I should teach Python. I insist the students should learn MATLAB. My reasons are

(1) many of the students have no programming experience; I mean zero. (2) it is a one unit course, just one hour per week, i.e., 13 contact hours including test time. Simply not enough time to cover Python. Am I wrong?

Here is my teaching schedule. Monday: 1-hr + 3-hr lectures; Friday: 4-hr lecture. Every time it is like running a marathon. How about your guys?

Any reason why the iOS app review status not changing for almost a week? While the Mac version has been rejected 2 times, not sure if they are related

Early June: Making an app for iOS 26. Late August: Not launching yet, already adapting it to iOS 27 October: Adapt it to the duo. Spend $1,999 to buy the duo to make sure the app runs on it without UI problem. Not even have any revenue yet …… 😪

bsky.app/profile/macr... Do I need one for development? It breaks my bank account. 😰

Here's What Apple Says About the iPhone Duo's Crease

macrumors.comHere's What Apple Says About the iPhone Duo's CreaseAhead of the launch of the foldable iPhone Duo, rumors suggested Apple was focused on eliminating the crease between the device's two displays. All foldables have a visible crease, and it often becomes easier to see over time from constant folding and unfolding. On the iPhone Duo product page, one of Apple's FAQs concerns the crease. "Does the inner display of iPhone Duo show a crease where it folds?" reads the question. Apple's response says the display is "wonderfully flat and smooth," but it doesn't say there's no crease at all and actually skirts the question it asks. iPhone Duo features a wonderfully flat and smooth inner display with custom nano-texture finish technology to reduce glare and reflections for an uninterrupted viewing experience. The optically clear adhesives let the display layers glide as the screen folds, minimizing stress and crease. In the press release for the device, Apple says that the Duo's nano-texture display is meant to minimize the visibility of the crease. A premium nano-texture finish reduces glare and reflections, creating a matte surface that minimizes crease visibility and feels great to touch. Apple does not list a fold cycle count anywhere in its press release or on its website, but it does say the hinge offers "smooth, balanced resistance for long-lasting reliability." Apple also says the hinge has more than 100 components, while the iPhone Duo has support ribs and a titanium panel under the display. Apple competitor Samsung does list fold cycles for its foldable devices. The new Galaxy Z Fold8, which has the same general shape as the iPhone Duo, is rated for 500,000 folds. The iPhone Duo is set to launch on October 23, with pre-orders starting on October 16.Related Roundup: iPhone FoldTag: September 2026 Apple Event This article, "Here's What Apple Says About the iPhone Duo's Crease" first appeared on MacRumors.com Discuss this article in our forums

Being a solo developer is tiring. Spending several months building the app. Then, producing marketing materials for the App Store and website. Three platforms required 30 screenshots, each of which has a tagline selling the feature. I can code for 10 hours a day, but marketing is too tough for me.
