That's why Vimium shows two or three character link hints when selecting links

In Vimium options only certain characters are allowed for link hints, which seriously limit the number of single character link hints. Allow more characters in the options.

XAMPP suddenly stops working, cannot connect

If there is no apparaent reason, no other program runs on the same port, there are no errors in the error log, XAMPP starts properly, etc. then try restarting your router if you have one. Sometimes my router gets confused or something and stops routing localhost traffic for some reason.

When doing the conversion, create a new conversion profile in the conversion dialog, enable video filters and there “image properties filter”, so the changed brightness value takes effect in the saved video.

Why it is easier to write a plugin for Emacs than VScode

As a long time emacs user I’m comfortable with Emacs, but I heard so much about VSCode that I gave it a try.

It’s certainly nice, many things work out of the box, the command palette is a nice touch (though a far cry from using Emacs with Helm) and the fact that most thing is accessible via the keyboard makes it a viable alternative.

So it’s like Emacs for the modern ages. Accessible, programmable. I can see myself using it for something in case it provides better support for some langugage than Emacs, though I still prefer Emacs, especially if LSP gives it equal footing in the future in terms of language support.

I tried to create a simple extension too and it was not too hard, but it required trial and errors and reading other extensions’s codes, because the documentation is pretty sparse.

The main takeaway about extensions for me is that VSCode provides an API which you have to use and it’s adequate if it provides the necessary access, but also limiting, because you can’t do things for which the vscode devs haven’t added support yet.

Also, the process of writing an extension is much more convoluted. You have to create an extension template with an npm command which fetches lots of packages into node_modules. Then you code the extension in vscode and trying it involves firing up an other vscode instance. There were mysterious errors when the extension did not work, but there were no error messages anywhere in the debug panel (turns out a node module I tried to use was not installed, but it was never reported to me, I only saw the error: the extension failed to start or something.)

Compared to this in emacs you simply evaluate some code in a buffer and it instantly becomes part of the editor. You are not limited by an API, because you can access the whole editor system. You can override core functions, etc. Of course, the greater power comes with greater responsibilities: you can break the editor if you reach too deep and not careful enough.

Conclusion: VScode is really nice, I like it, but I stil prefer emacs, because it makes it so easy to write extensions, you don’t even have to think about it. A small piece of code would be handy for a quick task? You just write it and it’s part of the editor. No registering an extension, no attaching to specific contribution points, no providers, etc. You just access what you need.

firefox increase menu font size, bigger font

1. In a new tab, type or paste about:config in the address bar and press Enter. Click the button accepting the risk.
2. In the filter box, type or paste devp and pause while the list is filtered
3. Double-click layout.css.devPixelsPerPx and change its value to 1.5 and click OK. That corresponds to 150% of the classic font size.

Too big? Try 1.25
Too small? Try 2.0
Don’t choose a value below 1.0 or about 4.0 or you may find it difficult to get back to a viewable Firefox! If something does go terribly wrong, right-click the preference and then tap the R key to reset to the starting value.

Vivaldi tab bar disappears by itself

It's some kind of bug and it's annoying. But turning off and on again the tab bar restores it.

In preferences you can assign a hotkey to showing the tab bar (e.g. Ctrl+Shift+A) in the view section of the hotkeys, so the disappearing tab bar can be restored with a hotkey.

Google ads don't appear: adsbygoogle.push() error: No slot size for availableWidth=0

Console shows this error: adsbygoogle.push() error: No slot size for availableWidth=0


Check if there is a responsive ad unit (e.g. with data-ad-format="auto") and media queries at the same time. The ad should either be responsive or you give the size. The two can't be mixed and it results in the above error.

This deletes the previous configuration settings which can have leftover settings which the new VLC cannot handle.

How to disable automatic spell checking in Skype

A reddit user provides the answer:

 there is a workaround for any Windows. Go to:

%userprofile%\appdata\roaming\microsoft\skype for desktop\dictionaries

Exit Skype, delete "en-US.bdic" (or whatever the name of the one you see there is), and then create a new dummy file by that name (you can right-click in Explorer, select New, and then choose Text Document--but be sure to rename it to the exact name, including extension).

Now right-click it, Properties, Security, Advanced. Disable Inheritance/Remove all inherited permissions from this object. Apply. Then OK out.

Now start Skype again and it will not be able to recreate the real dictionary file, as it otherwise would have done, and there will be no spellchecking.

All of the above, may need to be redone each time Skype upgrades.

Deleting undeletable Android apps without rooting the phone

It is possible according to this post. The solution is quite technical, though. I haven't tried it, but you'll have to start looking up what adb is, how to run it, etc. if you want to give it a try.  I just noted it down here, in case it's needed sometime.

Wireless mouse suddenly starts moving on its own

I have a Windows 8.1 laptop, but at home I use it with an external monitor and wireless keyboard and mouse. One day I got home and plugged the usb receiver of the keyboard and mouse into the laptop and started using it.

But anytime I used the mouse the cursor started moving left on its own. Very annoying. After digging a bit and trying solutions which recommended upgrading driver software and such which did not help, an article mentioned interference.

And lo and behold, some cables got twisted, got near the usb receiver and when I straightened them and moved them away from the usb receiver of the mouse, the problem went away.

So look out for interference from some cables if you use a wireless mouse and/or keyboard.
