I am interested to know how to quickly provide small to medium size web apps. In that context, low code and no code development platforms seem to be quite fascinating. But there seems to be a plethora of such development platforms! And the pricing for many seem to be based on per user which I presume is users using the app. That may be a big tripping point for many small organizations especially charitable organizations. One doubt I have is that if some of these low code dev. platforms are great then why all this buzz about MERN stack, Ruby on Rails etc. Instead the buzz should be about few of these dev. platforms that are great. I think I will get some idea of the answer only after I explore some of these low code dev. platforms myself. Plan to do that sometime in the near future, time permitting. ===================== 7 Best Low Code Development Platforms in 2024 [Full Software Demo], https://www.youtube.com/watch?v=NHcY7VetK10 , 15 min. 17 secs., published by Business Solution in F

Last updated on 29 Apr. 2024 In  Blogger Feed To HTML Book App  (BFTB), the updated key CSS code (as of 28 Apr. 2024) in blogbook page to minimize appearance of horizontal scrollbar in blogbook window is as follows (blogbook is the class used by body element; body element has one main element and two script elements; main-book is the class used by the main element; blogbook page source code ):       .blogbook {         padding-left: 20px;         padding-right: 20px;         display: flex;         align-items: center;         word-break: break-word;         word-wrap: break-word;       } ...       .main-book {         max-width: min(100%, 1200px);         margin: auto;       }       .main-book img {         max-width: 100%;       }       .main-book a {         margin-left: 0 !important;         margin-right: 0 !important;       }       .main-book pre {         overflow-x: auto;         white-space: pre-wrap;         word-wrap: break-word;       }       .main-book span {         white-s

This post currently simply captures some notes I have made on this issue and one solution for it. These notes are not organized. Time permitting I will try to improve organization of this post. For images with 640px width specification in a blog post, in  Blogger Feed To HTML Book App  (BFTB) when blogbook page CSS has a 'max-width: 100%' declaration for img elements, the blogbook page shows a horizontal scrollbar at window width less than around 700 px. If the blogbook page CSS declaration for img elements is changed to 'max-width: 90%', the horizontal scrollbar appears at only below around 160px width! Ideally the app. should not show horizontal scrollbar at 360px and above as then the app. will display in most mobile portrait mode screens without horizontal scrollbar. Earlier I did not have time to investigate why exactly the above was happening, and so was going with 'max-width: 90%' in the BFTB app. Recently I spent some time to investigate the issue and th

Last updated on 26 Apr. 2024 26 Apr. 2024 Update I think I now understand when such errors could happen. window.opener may be non-null but not the index page! I am not sure of the exact conditions when that can happen. But I think it can happen. I did some tests on localhost and I think I was able to recreate the same error but do not have the clear sequence of my actions. If window.opener is not null and not the index page then there may not be a updateBlogbookPage() function in it and so this error would happen. I am testing out various possibilities using a test project. I think the solution lies in naming the index page window and then checking whether the window.opener.name is the name of the index page window before invoking updateBlogbookPage() function.

F8 can be pressed multiple times to go further back in commands history ------- Sometimes my directory path for a VSCode project is very long and so when VSCode Terminal shows the whole path as part of its prompt, it is a distraction and tends to come in the way of viewing the terminal window contents. The notes below capture my efforts to solve the issue. So far, it is not fully successful.  Ref: Hiding the full file path in VSCode Terminal, https://anjikeesari.com/articles/hide-full-path/ But following above procedure to edit $Profile resulted in this error in VSCode every time I opened a Terminal window: . : File C:\Users\Ravi-user\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1 cannot be loaded https:/go.mic
