Use deep learning to 4x your photo’s resolution
As seen on TV! What if you could increase the resolution of your photos using technology from CSI laboratories? Thanks to deep learning and #NeuralEnhance, it’s now possible to train a neural network to zoom in to your images at 2x or even 4x. You’ll get even better results by increasing the number of neurons or training with a dataset similar to your low resolution image. The catch? The neural network is hallucinating details based on its training from example images. It’s not reconstructing your photo exactly as it would have been if it was HD. That’s only possible in Hollywood — but using deep learning as “Creative AI” works and its just as cool! Here’s how you can get started..

At the end of April 2014, Roman Yankovsky started a nice [Wayback] discussion on Google+ trying to get upvotes for [Wayback] QualityCentral Report #: 124402: Compiler bug when comparing chars.
His report basically comes down to that when using Ansi character literals like #255, the compiler treats them as single-byte encoded characters in the current code page of your Windows context, translates them to Unicode, then processes them.
The QC report has been dismissed as “Test Case Error” (within 15 minutes of stating “need more info”) by one of the compiler engineers, directing to the [Wayback] UsingCharacterLiterals section of Delphi in a Unicode World Part III: Unicodifying Your Code where – heaven forbid – they suggest to replace #128 with the Euro-Sign literal.
I disagree, as the issue happens without any hint or warning whatsoever, and causes code that compiles fine in Delphi <= 2007 to fail in subtle ways on Delphi >= 2009.
The compiler should issue a hint or warning when you potentially can screw up. It doesn’t. Not here.
Quite a few knowledgeable Delphi people got involved in the discussion:

Yay!
Windows 10 automatically restart the PC whenever it installed updates that required a mandatory reboot in order to finish installed. User can no longer delay or postpone a restart indefinitely. […]
The source Permanently Disable & Prevent Automatic Restart of Windows Update in Windows 10 – Tech Journey [WayBack] describes steps to fix a bunch of scenarios:
- Disable Reboot Task
- Stop the re-enabling of Reboot task
- Group Policy (but people reported that Windows 10 ignores the policy when comes to mandatory reboot required for installing updates)
- Prevent Updates from Installing by forcing your WiFi to act like a “metered” connection
- Prevent Updates from Installing by setting the Configure Automatic Updates setting in your Local Group Policy Editor
- For Windows 10 Home edition (that misses the Local Group Policy Editor) setting the above value directly in the registry

Interesting piece: Don’t Use Regular Expressions To Parse IP Addresses! [WayBack]
TL;DR:
When have neither then for quad-dotted decimal IPv4 addresses (ignoring for instance octals and grouped quads), this is suitable: regex – Regular expression to match DNS hostname or IP Address? – Stack Overflow [WayBack]
ValidIpAddressRegex = "^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$";
Which explained looks like this:
https://regex101.com/r/Wyr2Zd/1
Regular expression:
/ ^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$ / g
Explanation:
^ asserts position at start of the string
- 1st Capturing Group
(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}
{3} Quantifier — Matches exactly 3 times
A repeated capturing group will only capture the last iteration. Put a capturing group around the repeated group to capture all iterations or use a non-capturing group instead if you’re not interested in the data

Once you learn that shift/unshift are like push/pop on the other end of the array, you can mentally drop the ‘f’ from the name of the methods to remember which one ‘dumps’ elements and which one ‘inserts’ them. :)
