The curse of vulnerable OpenSSL DLLs
Posted by jpluimers on 2016/12/30
When you ship OpenSSL DLLs, you should provide an update mechanism outside of your regular product cycle that updates these shortly after vulnerabilities are fixed.
Few if any products do that. So I made an overview from products and OpenSSL DLL versions I had installed on various systems.
I’m a developer, so the list is biased towards tools I use often.
All of them are vulnerable: [WayBack] https://www.openssl.org/news/vulnerabilities.html

Getting A or better grading on SSL Labs HTTPS tests
Posted by jpluimers on 2016/12/30
Now that everyone has had enough time to get proper TLS certificates using for instance LetsEncrypt, it’s time to up the ante: score better than an A on the SSL Labs tests from either their main site or dev site:
Here are some links to get there:
- HOWTO: A+ with all 100%’s on SSL Labs test using apache2.4 (READ WARNINGS) – Server – Let’s Encrypt Community Support
- Getting an A+ on Qualy’s SSL Labs Tester

When you get “TfsScript.Execute” throwing a “Unregistered version of FastScript.” MessageBox
Posted by jpluimers on 2016/12/29
In recent Delphi version, FastReport version 5 ships. But for parts of FastReport, it’s a trial. This includes the FastScript part. The trial is very close to the real FastReport 5 thing. So real that when you compile you don’t see a difference, not even when trial and official things are mixed.
The only difference is that the trial will have a ShowMessage result like this:
ShowMessage(‘Unregistered version of FastScript’);
[Window Title] Fastscriptexecute [Content] Unregistered version of FastScript. [OK]
This occurred when I tried to move a the build process to a build server; a very tiny program will show this:
program FastScriptExecute;
uses
Vcl.Forms,
fs_iinterpreter;
{$R *.res}
var
fs: TfsScript;
begin
fs := TfsScript.Create(nil);
try
fs.Execute();
finally
fs.Free();
end;
end.
The build server had Delphi installed but not FastReports 5. I put all the sources in version control and fiddled with the project search paths until it built on the server.
Wrong!
Since the trial is so close to the real version, it will compile even if you don’t include all directories. In fact some permutations of the FastReports source and Delphi XE8 FastReports trial DUCs build perfectly fine.

Remove from a Git repository without deleting it from the local filesystem – via: Stack Overflow
Posted by jpluimers on 2016/12/29
For a file:
git rm --cached mylogfile.log
For a directory:
git rm --cached -r mydirectory
Thanks bdonlan for answering that: Remove a file from a Git repository without deleting it from the local filesystem – Stack Overflow

Firebird – date and time literals, conversion to ISO-8601 compatible strings
Posted by jpluimers on 2016/12/28
For my reference:
select 'Date literal values' as description
, (cast('now' as timestamp)) as nowTimeStamp
, (cast('today' as timestamp)) as todayTimeStamp
, (cast('tomorrow' as timestamp)) as tomorrowTimeStamp
, (cast('yesterday' as timestamp)) as yesterdayTimeStamp
, cast(cast('Now' as date) as varchar(10)) as nowDateCast
, replace(cast(cast('Now' as date) as varchar(10)), '-', '') nowDateIso8601
, cast(cast('Now' as time) as varchar(13)) as nowTimeCast
, replace(cast(cast('Now' as time) as varchar(13)), ':', '') nowTimeIso8601
, cast(cast('Now' as timestamp) as varchar(24)) as nowTimeStampCast
, substring(replace(replace(replace(cast(cast('Now' as timestamp) as varchar(24)), '-', '') , ' ', 'T'), ':', '') from 1 for 15) as nowTimeStampIso8601
from rdb$database
;
Output and transposed output:
