Every time he finds a new compiler use, I’m all like “wow!”. This time [WayBack] Stefan Glienke – Google+: One of these rare moments when the compiler positively impresses me found a new way to make single responsibility principle easier to attain by using a class helper to resolve interface delegation.
In the comments are a few nice tidbits on what the compiler emits in order to implement interface delegation and reference counting.

Cool stuff if you want to make your own WOL devices out of spare parts.
From old to new:
They can be woken up by anything sending magic WOL packets, including Raspberry Pi (which cannot be woken up by them, though you could use a Whack-on-LAN for that).
Basically the Raspberry Pi cannot be woken up with WOL because of a few reasons:
It can be a WOL server though: [WayBack] Raspberry Pi As Wake on LAN Server: 5 Steps (with Pictures)

If you dare using Delphi 10.3 Rio instead of waiting for Update 1 to stabalise (and hopefully speed up things), you might want to try the development snapshot of [WayBack] IDE Fix pack for Rio – Page 2 – Delphi Third-Party – Delphi-PRAXiS [en] that got released last week (thanks Andy!):
A new development snapshot of IDE Fix Pack for 10.3 Rio is available.
The Win64 (DCC64) and Android (DCCAARM) compiler patches should now work as excepted.
Changes:
- Added: Support for Delphi 10.3 Rio
- Added: Fix for TStringList.IndexOfName bug (RSP-21633)
- Added: Fix for access violoation in the Welcomepage JScript9.dll binding
- Added: TCustomListBox.ResetContent is skipped if the handle isn’t created yet
- Added: DFM Streaming optimizations
- Added: FillChar uses Enhanced REP MOVSB/STOSB cpu feature if available for large sizes.
- Added: Enabled CPU LOCK string assignment optimization for local variables
- Added: -Oe (experimental optimizations) and -x-cgo compiler option extension (Remove of some unneccessary push/pop operations)
- Added: Expression Evaluator allows array access to pointers even if the type wasn’t declared with {$POINTERMATH ON}
- Added: New compiler option extensions: -x–compileonly, -x–reslist, -x–depfile, -x–unitstats
- Added: More performance optimization for the DCC64 compiler
- Added: TStringBuilder.SetLength optimization [RSP-19178]
- Added: TStrings.GetDelimitedText optimization
- Fixed: Packages with duplicate units may not have caused a fatal compiler error.

A while back I wrote on Generating a million sequential numbers on the fly in a Firebird query – some solutions and speed measurements.
SQL Server has different features and performance characteristics so here are some links on doing similar things in SQL Server:
As always: if performance is important, measure before starting to optimise!

With the advent of WebSockets, it looks like TCP tunnels over HTTP/HTTPS are gaining more ground and I need to put some research time in them.
Some old to new links:
CONNECT requests are not supported by many HTTP proxies, especially in larger organisations, so chisel and crowbar have a much bigger chance there.
However, that is a VPN solution which is much broader than just a single TCP tunnel. You can so similar things with OpenVPN, but over HTTP/HTTPS, also requires CONNECT:
SoftEtherVPN seems to be more versatile though. I blogged about that before, but back then didn’t have needs for it yet. VPN over HTTPS: Ultimate Powerful VPN Connectivity – SoftEther VPN Project.

I need to document this properly later, but here are some links I used when fiddling with iframe elements:
A few things I learned:
float: left; in your style and a width: 100vw in the div around all your frames.100% isn’t 100% out of the box: default browser styles have a margin around your page and a border around an iframe.margin and border-width inside your styles for body and iframe. Easiest is to set them to none or 0.–jeroen

10 years after the publication of the [WayBack] Top 25 Most Dangerous Programming Mistakes, the list for me is still the same.
You can see this from the CWE/SANS revisions: 1.0 in 2009 until 1.0.3 in 2011: not much changed.

Interesting library with ditto command-line tools: [Wayback/Archive] oath-toolkit / oath-toolkit · GitLab.
It allows you to perform all sorts of OAUTH operations from your code or terminal window including generation and verification of OAUTH tokens through [WayBack] OATHTOOL.
Which allows you to do TOTP “zero fucktor” authentication. [WayBack/Archive] Zero Fucktor Authentication – Kristian Köhntopp – Google+: [WayBack] Zero Factor Authentication – The Isoblog.
The project has it’s home at [WayBack] OATH Toolkit, but the repository has done some traveling and for now ended up at GitLab: [Wayback/Archive] oath-toolkit / oath-toolkit together with the web-site source [Wayback/Archive] oath-toolkit / website.

Though the Google Calendar UI does not support EXRULE and EXDATE to exclude certain slots (via dates or rules) from recurring events.
