jimmar··on MdBook – a command line tool to create books with Markdown
I’m happy with mkdocs.
jimmar··on Notepad++ is 21 years old
I love Notepad++. My top 2 favorite features are macro recording and its search/replace (with options for normal, extended, and regex). It's fantastic for quickly cleaning up data.
jimmar··on Microsoft just delayed Recall again
I'd never owned an Apple computer until last week. I couldn't buy a new Windows computer knowing Microsoft's trajectory with intrusive tracking, Recall being the most prominent example.
jimmar··on 45 years ago CompuServe connected the world before the World Wide Web
CompuServe was my first experience connecting to the online world. I remember the "free parts" and the "per minute charge" parts. Young me thought that if I stayed in the "per minute charge" areas less than 60 seconds, it was free. It was not, and dad raised his eyebrows at the bill I generated that month.
jimmar··on Show HN: Xnapper Studio – Web tool for creating attention-grabbing screenshots
My images are being cutoff oddly. The top of 1/3 of my image doesn't display in the "default" setting. The full images shows in "iPad Pro H." The top 1/8th is cut off in the "Widows Web." The Windows Web only shows a white background with rounded corners--it it supposed to show the Windows operating system?

I'm not sure what the expected outcome is supposed to be, but I don't think I'm seeing it.

jimmar··on OpenAI Pleads It Can't Make Money Without Using Copyrighted Materials for Free
Nobody would train a huge model unless they wanted to use it. So I can understand concerns about training, even if the process of training alone does not produce content inspired by the training materials. People with copyright concerns rightly predict what the next step is going to be after the model is trained.
jimmar··on 80% of AI Projects Crash and Burn, Billions Wasted Says Rand Report
"Error establishing a database connection."

https://web.archive.org/web/20240826091915/salesforcedevops....

Here's a link to the Rand report: https://www.rand.org/pubs/research_reports/RRA2680-1.html

jimmar··on Big Pharma claims lower prices means giving up miracle medications. Ignore them
Why not make these same arguments for cars, food, or anything else that we buy? Just have the government negotiate maximum prices that manufacturers can charge. Maybe AI will help make cars cheaper in the future.
jimmar··on Linux desktop market share climbs to 4.45%
Linux seems to be stealing more market share from OSX than Windows: https://gs.statcounter.com/os-market-share/desktop/worldwide.
jimmar··on Launch HN: Firezone (YC W22) – Zero-trust access platform built on WireGuard
In the spirit of constructive feedback, spend the time and effort to record your product demonstrations in a more professional environment. Or generate a fake background at a minimum.
jimmar··on p5.js
Is there a JavaScript library that does animation using timelines, key frames, etc? It seems like p5js and several other animation libraries focus on things like partial simulations or other animations driven by mathematical formulas rather than animations done by placing objects on timelines and transforming them.
jimmar··on Got Ghosted names and shames companies that stop communicating
This will end up biased by the largest employers. Kind of like crime maps--they make it seems like there's an extraordinary amount of crime concentrated in urban areas, but that is due (in part) because that's where a lot of people live. A small company might ghost 90% of applicants and have a low count of ghostings, whereas a large employer might ghost 2% of applicants and have a very large count of ghostings.

This website could be improved by recoding employers who did not ghost applicants.

jimmar··on Show HN: A personalised AI tutor with < 1s voice responses
Interesting demo. I'd argue that a good tutor will ask more questions than answer. The tutor has to gauge the learner's understanding and adapt instruction. Properly formulating a question can be tricky if you're confused.
jimmar··on You got a null result. Will anyone publish it?
Not all null results are created equal. To get your null results published, the null result must shed light on some phenomena. And of course, the study must be sound. E.g., everybody takes for granted that X causes Y, but in a well-designed study, X did not in fact cause Y, which reveals an error in what we assumed was true.
jimmar··on 10% of Cubans left Cuba between 2022 and 2023
It's a complex issue, for sure, and I admit to not being well informed. I did a quick search, and Biden's administration allowed Cubans to open accounts with U.S. banks, but the Cuban government does not like giving up control. Cuba passed laws "forcing businesses to use Cuban banks for payment" [1].

jimmar··on 10% of Cubans left Cuba between 2022 and 2023
The UN, UK, and EU have no sanctions imposed on Cuba [1]. Why has no other country prevented Cuba from "starving to death?" Honest question. Is the United States so powerful that our trade is the only thing keeping countries alive?

jimmar··on Introduction to Bash Scripting
I've coded in a bunch of languages over my career, but somehow managed not to use bash. But a few weeks ago I found myself needing to create a somewhat involved script using Bash. Using GitHub Copilot, I was able to generate a script that worked great and it included comments, arrays, arguments, case statements, loops, conditionals, menus, etc--basically covering the first dozen chapters of this book. I guess my point is that we need to teach people what's possible and to help them explain what they want clearly. Memorizing syntax will be a less relevant skill at some point.
jimmar··on The VR Winter Continues
VR needs the killer app outside of gaming. It's currently too cumbersome to be seriously productive in VR compared to using traditional monitors connected to computers. Consumers aren't dumb. When a product adds real value, they'll buy it.
jimmar··on Half of Workers Around the World Are Struggling with Burnout
If I can give any advice in this area in a late mid-stage career, find a way to have productive conversations with your supervisor/manager. After about a decade of working in IT, I felt burnt out and left to pursue a PhD. Pursuing a PhD was my high academic achiever's way of dealing with burnout by doing something more intellectually stimulating. But 10 years into a career in academia, the symptoms of burnout can still creep up. But I'm mature enough now to speak up and make sure that I can continue working at a sustainable pace.
jimmar··on Sal Khan is pioneering innovation in education again
I work in academia and look forward to embracing AI tools. Students motivated to learn will do great with it. Others will need AI to really push them to learn, and it's not clear to me how that will work. Many students just want to know what they have to submit to get a grade. Spending 20 minutes chatting with AI about a topic might be a good learning activity, but incentivizing that with grading will be tricky.

I've sometimes wondered when I'll get called to the Dean's office because a student died in class because breathing wasn't specifically listed as a grading requirement on the syllabus.

jimmar··on The best way to have complex discussions?
I worked in a department that facilitated group discussions with a custom platform based on group decision-making research. One of the killer features of our platform was anonymity. Truth could arise in group discussions when people were free to comment, upvote, etc, without fear of retribution, being accused of playing polities, or just going with the crowd. Seeing everybody's name tagged in every comment in cq2 lets me know that people with uncomfortable ideas may be hesitant to post them. So I wonder what type of questions would be appropriate for the c2q type of tracking.
jimmar··on U-M finds students with alphabetically lower-ranked names receive lower grades
The article mentions that the paper is under review, but I'm guessing the effect size is small and that individual differences between graders is very substantial. The article states:

> The researchers collected available historical data of all programs, students and assignments on Canvas from the fall 2014 semester to the summer 2022 semester.

Thousands of students X 8 years X lots of assignments per year and you get a sample size so big that it would be hard not to find statistically significant effects.

jimmar··on U-M finds students with alphabetically lower-ranked names receive lower grades
Order effects are real. I'm a prof. I notice that the longer I grade, the less motivated I am to take off points and then justify why I took off those points. It's easier just to give points and move on. (And if anybody wants to criticize this, I'll be happy to launch into a diatribe on the psychometric dumpster fire that most assignments and their associated grading scales really are.)
jimmar··on The darker side of being a doctor (2017)
A brain surgeon saved my sister's life. In the days after her recovery, my dad ran into her surgeon eating in the hospital cafeteria at 11pm. My dad asked him when his shift ended and the surgeon just looked at him and said, "I live at the hospital." There was just so much work he had to do. Rewarding work, but grueling.
jimmar··on Math writing is dull when it neglects the human dimension
This was the "good" example:

> One of the main problems in gauge theory is understanding the geometry of the space of solutions of the Yang–Mills equations on a Riemannian manifold.

Perhaps I'm the wrong type of human, but this still does not resonate at all.

jimmar··on Show HN: I made a free animator. Think Adobe Illustrator but for animation
Very cool! It's a great balance of power and simplicity.
jimmar··on Heinz’s sustainable ketchup cap
Really smart move by Heinz--if only for the marketing and brand awareness alone. I doubt the environment outcomes will be significant, but the Heinz brand name has shown up in my feeds quite a bit in the past 24 hours because of this change.
jimmar··on A beginner's guide to making beautiful slides for talks
In my opinion, she buried the most important part under point 3 - "Slides should support your talk." Too many beginners see the slides as the presentation, and they are there to direct peoples' attention through the slides. People present. Slides support.
jimmar··on Big Pharma spends billions more on executives and stockholders than on R&D
It wasn't a rhetorical question. I could imagine an entity like the Gates Foundation proving seed funding to bootstrap a non-profit pharmaceutical company. That company could fund R&D through sales of its newly developed medicines. No shareholders. No stock buybacks. But somehow this doesn't seem to happen, at least not on a scale that reduces medical costs for consumers.
jimmar··on Big Pharma spends billions more on executives and stockholders than on R&D
It seems like we want for-profit pharmaceutical corporations to act like non-profit institutions. Any idea why non-profit institutions haven't risen in the world of pharmaceuticals?
