• I Prefer The Unary Plus (+) Operator Over parseInt() And ParseFloat() When Coercing Strings To Numbers In JavaScript

  Posted on Apr 5, 2020 at 10:36 AM

  @All, Worth mentioning, a number of people on Twitter responded that they like to use the Number() constructor for such things. As in: console.log( Number( "cb34d-234ks-2343f-00xj" ) ); // => NaN console.log( Number( "997da-00xj-2343f-234ks" ) ); // => NaN console.... read more »

• I Prefer The Unary Plus (+) Operator Over parseInt() And ParseFloat() When Coercing Strings To Numbers In JavaScript

  Posted on Apr 5, 2020 at 10:29 AM

  @All, After writing this, I've been struggling a bit with why I don't put a space after the + sign. For example, if I were to use one of the other unary operators, like the ! or !! (which really isn't an operator in and of itself), I would always put a space between the operator an... read more »

• Now Using utf8mb4 To Enable Emoji In My Comments

  Posted on Apr 5, 2020 at 8:01 AM

  @All, As a quasi-follow-up to this post, I started to think more deeply about how I might further leverage Emoji in my blog. The native chr() and asc() functions in ColdFusion only work for the Unicode range 0x0000 to 0xffff (or, 0 to 65,535). Once you go above that into the &q... read more »

• Zipping Image Archives With DEFLATE And STORE Compression Methods In Lucee CFML 5.2.9.31

  Posted on Apr 4, 2020 at 5:02 PM

  @Zac, To be honest, I have no idea what a tar file is :D This may be a silly question, but can any [common] computer open up a tar file? For example, if I was generating a zip/tar file for the user to download it, would double-clicking on it work for them? Or do you have to be more tech-... read more »

• Gathering CPU Load, Garbage Collection Time, Thread Dumps And Other JVM Metrics In ColdFusion

  Posted on Apr 2, 2020 at 7:40 AM

  @IsSet, Unfortunately, I'm not really a "java" guy 😞 As such, I don't really have an instinct for what is going wrong. My guess would be that your version of Java doesn't expose the same MX Beans? But that's really just a question. I am sorry that I cannot be more help.... read more »

• Pasting Images Into Your App Using File Blobs And URL.createObjectURL() In Angular 7.2.15

  Posted on Apr 2, 2020 at 7:30 AM

  @Akhil, Actually, looking closer at the deprecation notes, I do not think that it is fully deprecating all uses of URL.createObjectURL() . It seems to only say that it is being deprecated specifically when the argument is of type MediaStream . In my demos, the arguments are generally... read more »

• Pasting Images Into Your App Using File Blobs And URL.createObjectURL() In Angular 7.2.15

  Posted on Apr 2, 2020 at 7:17 AM

  @Akhil, Hmmm, very interesting. I just did some Googling and it looks like the new approach is to use HTMLMediaElement and srcObject . But, according to MDN, the support for that is not great: https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/srcObject MDN suggest... read more »

• Referencing String Characters Using Array-Notation In Lucee CFML 5.3.5.92

  Posted on Apr 2, 2020 at 5:16 AM

  @Charles, Yes, that's exactly right. But here's my emotional struggle: by the time you are going to start pulling in other methods like len() , I would probably just revert back to a simpler: value.right( 1 ) . That's why I think this is "interesting"; but, I'm not sure how o... read more »

• Experimenting With Chained Keyboard Events Using Event Plug-ins In Angular 9.1.0

  Posted on Mar 31, 2020 at 2:58 PM

  @Hassam, Great question ! I believe I happened across the EVENT_MANAGER_PLUGIN stuff by chance while reading someone else blog post a few years ago. The Event Manager itself is documented: https://angular.io/api/platform-browser/EventManager ... however , I don't see any docu... read more »

• Exploring The Power Of Multiple Cursors And Selections In Sublime Text 3

  Posted on Mar 30, 2020 at 7:38 AM

  @John, I personally use Sublime Text for everything including ColdFusion, AngularJS, Angular, and React. And, I haven't felt any points of friction. That said, I'm not really a "plug-in" person. I install plug-ins that do the color-coding for different syntaxes; but, other than... read more »

  Posted on Mar 29, 2020 at 4:43 AM

  @Charles, It's funny you mention that, re: loop , I've been using loop a lot lately, especially for Query objects. Much of the time, I am generating a JSON response based on a query; but, I don't use all the query data. So, I figure, "why convert the query to an array-of-structs ... read more »

• Exploring The Power Of Multiple Cursors And Selections In Sublime Text 3

  Posted on Mar 28, 2020 at 1:40 PM

  @All, To be clear, I am not intending to say that Sublime Text is the best editor; nor, am I saying it is better than your editor of choice. Just the opposite, I have to assume that all modern IDEs have this kind of functionality built into them. And, I would even guess that many of th... read more »

  @All, As a quick follow-up to this post, I wanted to look at using an INNER JOIN in a MySQL DELETE statement: https://www.bennadel.com/blog/3796-deleting-data-from-a-table-using-an-inner-join-delete-query-in-mysql-5-6-37.htm Being able to use JOIN constructs in both MySQL UPD... read more »

• Now Using utf8mb4 To Enable Emoji In My Comments

  Posted on Mar 26, 2020 at 4:34 PM

  @Pete, I modified the schema - it might be this piece that I am still missing: And you also need to make sure your database driver is using utf8, for mysql that might be adding useUnicode=true to the connection string. Though, I feel like we tried that at work, and we still needed ... read more »

• Array.Sort() Operator Must Return INT-Sized Result In Lucee CFML 5.3.4.80

  Posted on Mar 26, 2020 at 1:23 PM

  @Brad, Ah, :face-palm: -- I am so used to using .sort() in JavaScript , it didn't occur to me that the it might be documented differently in ColdFusion / Lucee. I am sure that I read the docs, but I probably glossed right over it. And JavaScript is explicitly documented to be loosey-g... read more »

• Gathering CPU Load, Garbage Collection Time, Thread Dumps And Other JVM Metrics In ColdFusion

  Posted on Mar 26, 2020 at 7:48 AM

  @IsSet, Wow, I have no idea. I wonder if it has to do with your version of Java? I'm still running all my stuff on Java 8 (1.8) I think. It sounds like you may be running on a newer version of Java that has some breaking changes. Here's what I get when I check my version of Java: ben> ... read more »
