Cheatsheet:
A; B Run A and then B, regardless of success of A
A && B Run B if A succeeded
A || B Run B if A failed
A & Run A in background.
Source: bash – Which one is better: using ; or && to execute multiple commands in one line? – Ask Ubuntu [WayBack]
Thanks Jack [WayBack] for the initial answer ubfan1 [WayBack] for getting the formulation right, Hatshepsut [WayBack] for making it a readable cheat-sheet and leftaroundabout [WayBack] for making this brilliant addition using parenthesis which can be used for all permutations:
(A && B) & In the background: run B if A succeeded

There are many sites potentially affected by the recently uncovered cloudflare memory leak bug below.
Read this list to get an impression: [WayBack] sites-using-cloudflare/README.md at master · pirate/sites-using-cloudflare
Basically you should change your passwords, 2FA authorisations and any other security hooks going through these sites. There are 1000s of them, including many major sites.
The reason for being so cautious is that the leaks have been cached on many systems, including Google Search. Many providers have scrubbed caches, but the information could still be in some caches, or the caches of end-user machines.

I had to re-logon to my mobile phone, but not my web browser. It seems this was due to a glitch at Google, but doesn’t remove my suspicion when I see this message come up in the future. So I did check account activity at these links:

A while ago I overheard an HR conversion about birth-date spreads which went into a topic on “default” birthdays being especially common in countries where the exact day of birth didn’t matter much. I got curious, so I dug up some links:
I remember a very long time ago seeing someones passport with zero as the birthday. Boy I wish I had taken a picture back then.

We have broken SHA-1 in practice.
This industry cryptographic hash function standard is used for digital signatures and file integrity verification, and protects a wide spectrum of digital assets, ranging credit card transactions, electronic documents, open-source software repositories and software updates.
It is now practically possible to craft two colliding PDF files and obtain a SHA-1 digital signature on the first PDF file which can also be abused as a valid signature on the second PDF file.
For example, by crafting the two colliding PDF files as two rental agreements with different rent, it is possible to trick someone to create a valid signature for a high-rent contract by having him or her sign a low-rent contract.

the release of 1.2 is almost there! We are working hard to deliver it shortly after the next Delphi release which will happen … soonish, I think. ;)
The release/1.2 branch has been around for a while – please take a look if you haven’t already. It contains a lot of new features and bugfixes. I will tell you more about some of the amazing features next time which won’t take as long as it took since the last blog post – promise. :)
Apart from a very interesting take on DI resolvers, the above great info too!
Please take a look at spring4d/branch/release/1.2 as it has been very stable for quite some time.

Some links that were useful getting back into using Delphi with resource scripts and include files:
Maybe I should have considered this alternative:
