Cool historic article: [WayBack] The Architecture of Open Source Applications: Sendmail by Eric Allman.
It is Chapter 17 of this book [WayBack]:
The Architecture of
Open Source Applications
Amy Brown and Greg Wilson (eds.)
ISBN 978-1-257-63801-7
I totally missed that book being published in 2014.
Great historic read!

A while ago, Google Drive told me it was out of storage.
I tried re-syncing, and then it suddenly told me a “Drive storage is full” message indicating “You have 3GB in your trash at drive.google.com. Empty your trash or upgrade your storage”.
You can view your trash at drive.google.com/drive/trash
Emptying is more tricky than you’d think:
The trash contained thousands of temporary PDF files: 3.2 GB, even more than Google Drive indicated.
These are not something I want to keep in the trash. Too bad Google Drive never warned me they were kept there.
On a different account that had way more file changes this saved more than 27 GB.
Maybe time to setup [WayBack] Google Drive Sensor | PRTG Network Monitor User Manual
Might be really interesting, as since 2015, [WayBack] PRTG 100 is Now Available For Free.

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.
