Trying to build a Linux Docker image for ASP.NET Core project with Typescript support leads to a build error "MSB6003: The specified task executable "node" could not be run". The reason is Linux. On Windows, Microsoft.TypeScript.MSBuild includes tsc.exe. On non-Windows platforms, such as in a Docker container, Microsoft.TypeScript.MSBuild does not include ts.exe and instead shells out to a Node for the TypeScript compiler. The official dotnet/sdk Docker images I think included Node at one point in the past, but they no longer include Node. You will either need to make or find a Docker image with both the dotnet-sdk and Node, or configure some multi-stage build involving the official Node image [ 1 ]. Ok, if I know the reason then I will solve it in a minute. I thought. It turned out to be a quest to install the actual version of Node. Official Microsoft's image for dotnet is based on Debian (12 at the moment for .NET 8.0). So, the straight forward way would be u

Introduction: In the age of technological innovation, artificial intelligence (AI) has undeniably reshaped the landscape of content creation. While the emergence of AI-generated content brings forth opportunities for efficiency and scale, it also introduces challenges that warrant careful consideration. This article delves into the impact of AI-generated articles specifically on the professional networking platform LinkedIn. Our focus will revolve around the critical aspects of transparency, ethical considerations, and the indispensable role of human oversight in maintaining the integrity of information. The Rise of AI-Generated Content: Artificial intelligence, exemplified by powerful models like GPT-3, has ushered in a new era of content creation. Its ability to mimic human language and generate contextually relevant text has found applications ranging from marketing strategies to the development of virtual assistants. The Pollution of Informational Space: Lack of Accountability: One

I worked a lot with async functions in languages other than Python. It's usually very straight-forward and easy to find any answers in internet. It was a surprise that solving a very simple question regarding async in Python took me a day. How to execute an async coroutine in a classic synchronous function? Async library author's position and CPython's GIL made execution of async functions synchronously harder than required. Instead of an exact answer dozens of answers on StackOverflow explain why it is not possible or a bad idea (and a handful of not working suggestions). Ok-ok, I just need a solution! I had to understand how asyncio works to solve this. So, this code allows to synchronously wait for execution completion of async coroutine without a hot spin-lock: def sync_exec ( coroutine : Awaitable ) -> Any :     try :         asyncio . get_running_loop ()     except RuntimeError :         loop = asyncio . new_event_loop ()         return loop . run_until_complet

After recent Thunderbird update (v60) which screwed HTML composing even more, to unusable state, I decided to review alternative Windows desktop email clients to replace it. Once again. I have an intention to replace Thunderbird for a long time but there are no real competitors. Does something change in 2019 ? Thunderbird https://www.thunderbird.net/en-US/ Let's review Thunderbird itself first to use it as a base for comparison: Pros: + It has everything modern email client has to have + If it doesn't have something you can extend it with numerous add-ons + Embedded calendar add-on with support of external calendars (Google, ical) + Support of external contact books (Google) Cons: - The only major flaw is its HTML editor. It was not ok previously but they made it even worse in version 60. Verdict: Everything is ok but, damn, is it possible to incorporate some decent HTML editor in it? Outlook https://www.office.com/ The obvious choice is Outlook, the mos

I have created a js script to automatically convert currency on page according to the current rate. Lets say I write "$5" and want to show its value in other currencies. I just need to enclose it in a tag with class = "exchange" and voila: $5 . To enable this behavior you need to link jQuery (add <script src="https://code.jquery.com/jquery-2.1.4.min.js" type="text/javascript"></script> to the head of page) and the script itself (add <script src="https://drclnatj7kvk6.cloudfront.net/currency.js" type="text/javascript"></script> to the bottom of the page). Script is based on http://fixer.io/ and http://openexchangerates.github.io/money.js/ . Fiddle is available here:  https://jsfiddle.net/40rr05fb/42/embedded/result/ . Language and displaying currencies can be easily set. Extending the script is also straightforward. If you dont see the magic, its Google Blogger's issue. Go into the arti

I have spent some free time to port a control from VB.Net to C# and refactor it a little bit. This UI control attaches to RichTextBox and displays line numbers for the text. The control has many settings and re-paints quickly and exactly. You may get it here: https://github.com/antgraf/C--Numbered-Lines-Control-for-RichTextBox--LineNumbersControlForRichTextBox-
