IE11 and broken scrolling

When I first installed Windows 10 preview on my laptop, IE11 scrolling stopped working when using the touchpad to scroll. Interestingly scrolling worked great in all other programs: explorer, outlook, one note, and many others. For IE11, unless I click on the tab title, and avoid clicking on anything else in the tab area, scrolling did not work. It was quite an annoying behavior, but not a show stopper for trying out Windows 10. I ended up learning how to use the keyboard for scrolling through the web pages in lieu of touchpad goodness.


With preview updates, the problem did not get any better, so I searched on the web to see if the issue was widespread. It turns out that it was, and it was not restricted to Windows 10 preview either. There were a lot of solutions online, that did not make much sense, like resetting IE11, going to the advanced tab and disabling smooth scrolling, and a slew of others. The one that made sense was a problem in the Synaptics driver, which for older style applications such as IE11 sends the wrong scroll messages to the scrollbars. The fix was obvious, upgrade the driver to the latest version. After upgrading  to 19.0.12.61, touchpad scrolling worked again in IE11. I still use the keyboard shortcuts though.

Emacs on WSL2: From Monochrome Misery to Modern Elegance

Windows Subsystem for Linux (WSL) has come a long way—especially under Windows 11 . WSL2 now offers smooth integration for Linux graphical applications, making it feel less like a compatibility layer and more like a native experience. But if you're an Emacs user, you might have noticed something off. Launching Emacs under WSL can feel like stepping into a time machine. Tiny fonts, washed-out visuals, and a UI that evokes the green-and-amber glow of vintage terminals. Functional? Yes. Pleasant? Absolutely not. But here's the good news: it is easy to make Emacs under WSL2 look just as sharp and modern as it does on Mac OSX . The emacs-pgtk build is designed for better graphical integration under WSL. It uses the Pure GTK interface , which plays nicely with WSL’s GUI support. sudo apt install emacs-pgtk To make Emacs look great, we’ll use Windows’ rich font library. First, edit your font configuration: sudo emacs /etc/fonts/fonts.conf and add the Windows Font directory...

MacOS Catalina, OneDrive, and case sensitive file systems

Over the weekend, I dusted off my old Macbook Air to search for some old family photos. I have not used the laptop for a long time, and it was completely out of charge. I plugged it in, and it quickly booted. Shortly after, I got bombarded with notifications that many of the applications needed updating, and that a new version of the OS was available.   I waited till I found the photos I was looking for, before attempting to upgrade anything. I also wanted to install OneDrive to get my old files to the cloud, so that I can access them from any of my devices, instead of dusting off old computers to get to them. The MacOS upgrade experience has always been fantastic, and this one was no different. The OS upgrade files downloaded quickly and after a restart and a quick install, the Macbook Air was ready to go.   Upgrading the installed applications was also a breeze, however in the process I discovered that a large majority of the applications installed were not compatible ...

Randomized Algorithms: Polynomial equivalence

We are all accustomed to deterministic algorithms; we work with them every day, and feel comfortable in knowing that the results of running them are predictable, barring a coding error of course. The idea of randomized algorithms feels remote and uncomfortable, despite their usefulness and elegance.  There are a couple of great examples in the introductory chapters of the book " Probability and Computing " that are an eye opener. One is verifying polynomial identities: how can you tell that two different representations of polynomials are the same? For example, if we have two polynomials $P(x)$ and $Q(x)$, both of degree $d$ described by the following formulas: \[ P(x) = \Sigma_{i=0}^{i=d} a_i x^i \\ Q(x) = \Pi_{i=1}^{i=d} (x-b_i) \] how can we determine that they are the same polynomial? Intuitively we first check that the degrees are the same, then we could try to transform one form into the other, either by multiplying out the terms for $Q(x)$, collecting like t...
