Inkscape is on GitLab, not GitHub

So, I saw that Inkscape had a GitHub repository that points to GitLab. Did it move after the Microsoft acquisition? No, it was always there. It moved from Bazaar and Launchpad to Git and GitLab.

So, now I’m wondering. Would GitLab work for me? Looks like it would, as there is a GitLab pages analog to the GitHub Pages of GitHub.

So, you’re wondering. Is the MS-DOS Encyclopedia available as an Ebook? Oh, now that’s a trick question. The MS-DOS Encyclopedia is available online, but not as an official Ebook. There are some plain text files corresponding to what you would have originally seen were you to download it and read it on your own MS-DOS computer.

Interestingly, one of the early versions of the MS-DOS Encyclopedia inadvertently revealed some Microsoft __ information, so it had to be recalled from the shelves. This happened even though the MS-DOS programmers reviewed the book before publication.

I found one very interesting subject from Twitter: a new AI to continue stories where you left off. This will be very useful to me for some of my hobbies… once it is publicly released. For now, they are staying somewhat secretive about this technology for fear of it spawning a new generation of fake news and fake reviews.

Here are two interesting articles on continuous partial attention.

In the midst of the discussion in the comments on one blog article on the Let Grow website, I found another interesting blog. I saved a sampling of some of the articles and related information here. Candice H. Brown Elliott is a significant innovator in flat panel display technology. She is the one who brought forth the PenTile subpixel layout.

One of the problems I’ve identified with me not getting around to practicing soldering as frequently as I like is due to lack of protective equipment. Can I practice soldering late at night? What if I make a mistake and burn myself? By far, I must admit that my two greatest concerns with soldering are the fumes and the potential to burn my hands on the soldering iron. Also, reading around, some people always recommend you wear a respirator while soldering, so why not?

Okay, now what about the gloves. What kinds of gloves should you wear when doing soldering? First of all, many people do not recommend wearing gloves due to the lost dexterity. Fair enough, but if you are a novice at soldering, you don’t have much dexterity to begin with, so that’s not really something to worry about. Of course experts are much less likely to burn themself on soldering, even if they are doing it late at night. But, anyways, for those who do prefer to wear gloves, they recommend wearing “welding gloves.” They are very comfortable, and they will stand up to the heat if you accidentally touch the tip of your soldering iron. Your main concern with gloves is that they must be sufficiently heat resistant, because having a burnt glove stick to your burnt hand is not very comfortable.

So, you opened up an electronic device, and there are some fancy components like 6-segment digital LCD screens taht you’d like to salvage for use in hobby projects. But alas, you see that your desired component is glued onto the circuit board! How do you get it off?

Some background knowledge is very useful in devising a strategy for removing pesky bonding materials. There are three main methods of removing bonding materials:

  • Mechanical: These are strictly methods that involve cutting at the bond with a knife, rubbing at it with sandpaper, or going all out with a rotary cutter to really grind down that pesky bonding material!

  • Thermal: Heat up the bonding material so that it melts or softens.

  • Chemical: Use some sort of acids to dissolve your bonding chemical.

Typically, if you have no idea what you are working with, the easiest and safest method is to go with a combination of mechanical and thermal removal. Heat up the joint in hopes that doing so will soften the bonding material, as is the case with some types of epoxy. A hairdryer is the go-to DIY hobbyist tool to get started on this, but if you are better equipped, you may go with a heat gun or a heated knife instead. Anyways, once you’ve got your joint heated, cut away at the joint with a utility knife.

Three years ago, I put together some useful open-source software and made some useful modifications to it in order to migrate a giant CVS repository to Git. I’ve wanted to share this information for quite a while, but I wasn’t sure of the ideal form to share it. Recently in the past few months, thinking things through, I became aware: of course, if you’re making modifications to this software that will tend to become out-of-date, your goal is to create a list of instructions that a human can follow to make similar modifications to later versions of the software. So, here I am, writing a blog article as my means to this end.

As this project was very rushed with limited resources, I was unable to make my modifications in a way that would be elegant enough to merge to the official upstream versions of the software in question. (Of course it would be that way if people wanted to get it done as fast as possible!) So, although that would be the perfect ideal where you wouldn’t need to make any modifications at all, we have to cope with falling short of that ideal with this pretty good second place compromise.

So, first of all, let’s point out the open-source tools that I’ve used.

Updates on EOMA68

Are there any updates on EOMA68? Yes! Wow, that’s good to know that some progress is being made… although they do state that they are indeed behind schedule. Also, they do note that the EOMA68 board is not vulnerable to Spectre, just as I have already been assuming.

So, I happened to randomly look up “reticle” and Wikipedia, then I got thinking… I’ve already thought about this before. Are gun sights a good place to look to for inspiration on creating a cheap camera viewfinder? Earlier, I concluded the answer was “no” because the primary purpose of a gun sight is to focus only on a narrow center target, but for a camera, you want to know the full details that are in the field of view. Nevertheless, some of the information is interesting and insightful.

Mary Babnik Brown donated her hair for use in the crosshairs of the Norden bombsight. The Norden bombsight was intended to be highly accurate and advantageous over previous designs, but real-world use proved it wasn’t much better.

Here I go again, yet another article from the Mr. Money Mustache blog. “What if everyone became frugal”? Would the economy collapse? Not so. Actually, things would work out just right, maybe even better. Some of the current issues that the United States is experiencing may be closely related to consumerism.

Again, I reiterate, because this is important! Mr. Money Mustache has also wrote a blog article on the science of human time perception, with a personal twist. His perspective of being an early retiree has brought to him many moments that made him feel like he has experienced a whole human lifetime in only a very short amount of time, maybe having experienced even more than a whole human lifetime.

Now I list a few other interesting links to articles I’ve read through. Constant optimization, habits, your free time is valuable, the advantages of biking, and other financial independence groups? Well, they go by quite reasonable names like ChooseFI.
