In [WayBack] How to remember password in FortiClient VPN? – Stack Overflow, the consensus seems to be “it varies, and usually is unreliable”.
Time to write a tool that snifs the Windows GUI and auto-enters the credentials.
That would be much like the Linux expect solution: [WayBack] Continuous run Forticlient VPN using expect. Automatically restart VPN if get disconnected or session closed. · GitHub

A long time I wondered why I saw ESXi systems on my local network have two entries in their /etc/hosts file:
[root@ESXi-X10SRH-CF:~] cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost.localdomain localhost 192.168.71.91 ESXi-X10SRH-CF ESXi-X10SRH-CF
Then I bumped into someone who had a different setup:
[root@ESXi-X10SRH-CF:~] cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost.localdomain localhost 192.168.0.23 esxi.dynamic.ziggo.nl esxi
So now I knew that the first entry can have a domain resolving it (it still makes be wonder why ziggo is using a top-level domain to resolve local stuff; but searching for dynamic.ziggo.nl did not get me further on that).
So I installed a quick ESXi machine on that local network, and got the same.
When back home the machine still thought it was esxi.dynamic.ziggo.nl, though clearly I was outside a Ziggo network
I wanted to get rid of it, but that was hard.
Since I forgot to take screenshots beforehand, I can only provide the ones without a search domain bellow.
Reminder to self: visit someone within the Ziggo network, then retry.
Normally you can edit things like these in the default TCP/IP stack. There are two places to change this:
Neither of these allowed me to change it to a situation like this, but luckily the console did.
In the below files, I had to remove the bold parts, then restart the management network (I did keep a text dump, lucky me):
[root@esxi:/etc] grep -inr ziggo . ./vmware/esx.conf:116:/adv/Misc/HostName = "esxi.dynamic.ziggo.nl" ./resolv.conf:2:search dynamic.ziggo.nl ./hosts:5:192.168.71.194 esxi.dynamic.ziggo.nl esxi [root@esxi:/etc] cat /etc/resolv.conf nameserver 192.168.71.3 search dynamic.ziggo.nl [root@esxi:/etc] cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost.localdomain localhost 192.168.71.194 esxi.dynamic.ziggo.nl esxi

This LSI 3008 HBA update to TI firmware is still on my wish list, but I could not find it when I bought the board in 2018.
[WayBack] Supermicro Single CPU Board for ESXi Home lab – Upgrading LSI 3008 HBA on the X10SRH-CLN4F | ESX Virtualization:
As you know my lab got an addition this year with Supermicro’s Single CPU board, the X10SRH-CLN4F. In this post we will be upgrading LSI 3008 HBA on the X10SRH-CLN4F.
…
I have learned a new way to patch via UEFI. In fact, it’s same (or easier) than through DOS-based bootable USB. The IT firmware can be reverted back to IR firmware as in the ZIP package there are both versions there. So in case you need a server with hardware RAID, you can use the IR version. I was actually wondering what it means the IT and IR and here is what I have found at LSI (Avago) website:
“IT” firmware maximizes the connectivity and performance aspects of the HBA. “IR” firmware offers RAID functionality via RAID 0, 1, and 10 capabilities.
Via:
I just ran across this today – Supermicro posted new firmware on June 18, 2016 for the Avago/LSI 3008 SAS chip found on the X10SRH-CLN4F.
This version FINALLY pairs up with the driver version contained in the current version of FreeNAS 9.10.xxxx. P12 firmware is currently correct for the V13 driver in FreeNAS 9.10.3008_FW_PH12.00.02.00.zip
The step afterwards is to enable SR-IOV for this LSI 3008 HBA.
These links should help with that:

Reminder to myself to check out of the Tidy First? book by Kent Beck got out yet.
I discovered he was writing it after reading this tweet:
Like Extreme Programming, which I used before I even know about the term, Tidy First is my natural way of approaching code: step by step tidying small spots, so I get a feel on the why and how of the code. For me, tidying consists of very small refactorings. I am anxious to see what it means for Kent.
Related links:
The Limbo song asks, “How low can you go?” Limbo is a strategy for scaling collaboration on software projects by reducing the size of changes to be merged and increasing the velocity and reach of propagation of changes.
As I got started with Tidy First?, my long-contemplated book on software design, I found myself in a sequence of oh-so-familiar situations. I realized that book writing has a rhythm for me. To help you quell the desire to write a book of your own, here are the steps.

Interesting idea by Cesar Romero (who has some interesting repositories at [WayBack] cesarliws (Cesar Romero) · GitHub and [WayBack] cesarliws — Bitbucket) when using TestInsight for Delphi: first test if TestInsight is running at all: [WayBack] foundation-4-delphi/Foundation.Test.Utils.pas at master · cesarliws/foundation-4-delphi · GitHub.
function IsTestInsightRunning: Boolean; {$IFDEF TESTINSIGHT} var TestInsightClient: ITestInsightClient; begin TestInsightClient := TTestInsightRestClient.Create; TestInsightClient.StartedTesting(0); Result := not TestInsightClient.HasError; end; {$ELSE} begin Result := False; end; {$ENDIF} procedure RunRegisteredTests; begin ReportMemoryLeaksOnShutdown := True; {$IFDEF TESTINSIGHT} if IsTestInsightRunning then TestInsight.DUnit.RunRegisteredTests else {$ENDIF} DUnitTestRunner.RunRegisteredTests; end;
Another interesting bit from the same library is the deferer pattern (which is different from the promise pattern!) in [WayBack] foundation-4-delphi/Foundation.System.pas at master · cesarliws/foundation-4-delphi · GitHub with the below code examples.
I think a better name might be DeferExecutionToEndOfScopeFor.
procedure ProcessFile (const FileName: string); var File: TFile; begin File: = TFile.Open (FileName); Defer (File.Close); while not File.EOF begin // ... process file end; end; // Defer will be executed here [File.Close] procedure ExecSql (const ConnectionString, Sql: string); var Database: TDatabase; Exec: IDeferred; Query: TQuery; begin Database: = TDatabase.Create (ConnectionString); Exec: = Defer (Database.Free); Database.Open; Exec.Defer (Database.Close); Query: = Database.Query (SQL); Exec.Defer (Query.Free); Exec.Defer (Query.Close); if Query.IsEmpty then Exit; while not Query.EOF begin // ... process query end; Exec.Defer ( procedure begin Writeln ('Finished ExecSql'); end ); end; // Defer will be executed here [Writeln, Query.Close, Database.Close, Database.Free]

compact-directory-recursively.bat:
if [%1]==[] goto :eof call compact /s /c %1 %1\*.*
Example usage:
compact-directory-recursively.bat C:\ProgramData\{51D553F1-B483-41C2-B35E-6D461D9E0F9C} compact-directory-recursively.bat "C:\ProgramData\Package Cache" @for /d %d in (*.*) do @call compact-directory-recursively.bat "%d"
The @ signs are to get less output clutter.

For past timestamps (or date-times), as long as you know the associated location, you always know the time zone rule that applies, no matter if you store them in UTC or local time zone.
For future dates, UTC might not be the best option, as you have no knowledge on future time zone rules. There you need to have at least three fields:

From a check-in a while ago, when some Delphi versions complained about CallerAddr having been replaced by ReturnAddress and other versions not understanding ReturnAddress, but having CallerAddr.
The code in the [WayBack] gist and on [WayBack] BitBucket:
ReturnAddressUnitto provideReturnAddressto Delphi versions not supporting it, and preventCallerAddrwarnings for Delphi versions havingReturnAddress. See https://bitbucket.org/jeroenp/wiert.me/src/…/Native/Delphi/Library/RTL/ReturnAddressUnit.pas
Basically the code maps a variable having a variable ReturnAddress that is a function reference returning a pointer to a function and redirects to CallerAddr when there is no ReturnAddress available. This is the case for anything below Delphi XE2, and avoids W1000 Symbol 'CallerAddr' is deprecated: 'Use ReturnAddress' for Delphi XE2 and up
It is an extract from [WayBack] dunit-extension/TestCaseExtension.pas at master · fabriciocolombo/dunit-extension · GitHub.
There is more interesting code in [WayBack] GitHub – fabriciocolombo/dunit-extension: Extended DUnit TestCase provides assertions to the types Date, Enumerator, Double, and other types, and a class to help run tests with output as XML, text and GUI mode and even more in [WayBack] fabriciocolombo (Fabricio Colombo) · GitHub , which are on my list of things to play with in the future.
Some more [WayBack] commits are at [WayBack] GitHub – cesarliws/dunit-extension (more on [WayBack] Cesar Romero tomorrow).
I think the code from Fabricio is inspired by [WayBack] ZeosLib/TestFrameWork.pas at master · svn2github/ZeosLib · GitHub as it uses the same HAS_BUILTIN_RETURNADDRESS define.
The code by Fabricio is smarter though.
