It's possible you came to the blog looking for a post at a particular URL, but nothing was found. This may be because I recently shifted the URLs of some posts. This reason for this is that recently, when looking at some older posts, I noticed something odd, which is that their URLs did not properly reflect their posting date.
Normally on blogspot, the way it works is this: The URL starts out with the name of the blog, followed by dot blogspot dot com (or in some cases, omitting the dot blogspot part), slash, the year, slash, the month, slash, the first few words of the blog post and then a dot html.
So for example, this blog post's should be https://sometotallyrandomthoughts.blogspot.com/2026/03/a-note-regarding-urls.html. After all, it was posted March of 2026, so you see the 2026 in the URL to show the year, the 03 to show the month, and then what comes afterwards which is taken from the title. Normally, this is automatically done. However, I happened to notice that a number of posts, while having the correct dates of publication, had the wrong URLs. So for example, it would have been as if this post's URL, despite the posting date of March of 2026, had 2025 in its URL.was instead https://sometotallyrandomthoughts.blogspot.com/2025/02/a-note-regarding-urls.html even though it was posted on March of 2026 rather than February of 2025.
I'm not sure exactly how that happened. My guess is that somehow, the Permalink option (in which you set what you want the URL to be) somehow got the "Automatic Permalink" off. Normally Automatic Permalink just sets it up the way I described before, with the applicable dates in the URL followed by the title. So I think what might have happened is that somehow the automatic part got turned off and it got "stuck" on an older URL date, even though it was posted later. Since posts often spend a lot of time in draft before ever getting posted, this can cause the URL to therefore reflect the old date of editing (one of the posts was actually years off in its URL). This bugged me a bit, so I went and corrected the URLs to correctly fit with the dates of publication. I think I got all of them.
The downside of this is that it means someone might then try to go to the old URL, which would then give you a blank page. So I thought I should write up this post to explain the matter. If this happens to you--you try to go to a post and it's missing--try doing a search for the title of the post (which you can see the early words of in the URL itself) and it should show up.
This change probably won't make too much of a difference to people, because I don't get many views on this blog anyway; most have no more than a few dozen, and the most popular post barely clears 300. Also, I'm pretty sure at least half of all views on this blog are from robots. Most of the views of actual people probably come from search engines rather than links. Fortunately, the posts people might have actually linked to directly, that is the more popular ones (well, more popular than than the rest of the blog, at least) didn't need to have their URLs changed. So the search engine thing is what is most likely to happen, but search engines can sometimes take a while to update things (and in the meantime link you to the wrong ones), so you might have stumbled across a page before they got the stuff updated, and I thought I should put up this post to explain that.
Of course, the problem with one of these is that it will inevitably get pushed off the top of the posts as new posts are made, meaning as time goes on its usefulness will be decreased; but as noted, the most key point here (search engines) should be getting themselves updated by then, so most likely by the time this gets pushed off due to new posts, anyone who actually stumbles across this blog via some kind of search engine will have the correct post linked by the search. In the off chance this actually caused confusion, I apologize, but I did want the URLs to be accurate. I believe I changed all of the links within the blog itself--that is, when one blog post links to another blog post--so that they link to the updated ones, but if there are any that don't work, feel free to leave a comment mentioning it.
