The hard part of a crypto specification: make it safe and misuse resistant.

Posted by jpluimers on 2021/10/19

Great quote from a while back:

[WayBack] Filippo Valsorda on Twitter: “Here’s a secret: it’s not that hard to put together a crypto specification. What’s hard is to make it safe and misuse resistant. What needs to be “battle tested” is the security devex, not the narrow happy path, and blaming the developer when it breaks is not battle testing.”

From the same thread:

EProgrammerNotFound exception in Delphi? – Stack Overflow

Posted by jpluimers on 2021/10/19

From a long while my answer to [WayBack] EProgrammerNotFound exception in Delphi? – Stack Overflow (I added the WayBack links)

It was introduced in Delphi 2009, still present in Delphi 2010, and [WayBack] recently got some [WayBack] more attention on the [WayBack] internet.

I think it is an easter egg, similar to [WayBack] “EBCAK” (Error Between Chair and Keyboard), and the [WayBack] skipping of Delphi version number 13.

[WayBack] EProgrammerNotFound

  • is declared in the Win32 branch of the SysUtils unit, but not used anywhere in the RTL or VCL
  • is not present in Delphi Prism
  • was introduced in Delphi 2009, so not present in VCL.NET
  • has currently (version 3.5) nothing similar in the .NET framework (not sure why, these guys [WayBack] do have humour)

I don’t think EProgrammerNotFound is actually meant to be used at all, but since it is there, people will jokingly use it (similar like putting a stray “const False = True; True = not False;” in someone elses sourcecode).

On green bits and red bits (which I highly associate with the “green wobbly bit”:

The Charlie Calvert “Here’s to Good Friends and New Adventures” article

Posted by jpluimers on 2021/10/14

Since this contains a list of contains from back then (20+ years ago!), I save it for future reference: [WayBack] Here’s to Good Friends and New Adventures

I would like to make a very short list of the other people at Borland who I have had the privilage of working with very closely. These people are Jason Sprenger, Xavier Pacheco, Steve Teixeira, John Kaster, Lar Mader and Rich Jones. Each of these people I worked with every day over a period of years, and they never showed me anything but the very best and most admirable human traits. I hope I am so lucky as to work with such fine people again in my life.

As for all the others, there is no way even to begin to thank them. A few of these people are Karen Giles, Lino Tadros, Steve Trefethen, Christine Ellis, Paolo Ciccone, Yolanda Davis, Blake Stone, Bruneau Babet, Dave Marancik, Anders Ohlsson, Dave Powell, Claudio Briceno, Joe Manzone, Terri Bartos, Dave Wilhelm, Andrea Ginsberg, Jason Vokes, Ludo Neveu, Martin Pamdeth, Martin Raim, Ernesto Franchini, Edwin Desouza, Zack Urlocker, Rosemary Abell, Robert Warren, Scott Bussinger, Richard Morris, Paul Beach, Jeremy McGee, Nimish Vora, Michael Swindell, Lorie Hull, Kendyll Upstrom, Kari Gallant, Allen Bauer, Josh Dahlby, Jose Rubens, John Thomas, John Williams, J.D. Hildebrand, Hizo Jozsef, Goran Kallmark, Ben Riga, George Cross, Gary Benner, Fred Felman, Erik Jakowitz, Danny Thorpe, Craig Farrell, Claudia Currie, Bill Weber, Lance Devon, Robert West, Amber Hein, Richard Kubat, Jeff Peters, Ellie Peters, Krystyna Niedzwiedzka, Kathy Berkland, Kelly Welty, Tom Lam, Nester Miranda (and Carlos!), Dana Kaufman, Pawal Ksiezyk, Jim Wright, Lori and Ellen from travel, Sergey Orlik and many others who I just don’t happen to recall right now, or who I liked very much but only met a few times.

I’m also indebted to Ray Kanopka, Mark Miller, Dick Malley, Dan Horn, Taco Oosterkamp, Bob Swart, Ann Lynnworth, Marco Cantu, Jeroen Pluimers, and many more who worked in the Borland community and brought me great joy. It’s amazing to consider how many talented and remarkable people have been drawn to this company.

Raspberry Pi Turn Tv On/Off CEC – Tim Leland

Posted by jpluimers on 2021/10/13

[WayBack] Raspberry Pi Turn Tv On/Off CEC – Tim Leland (with some quote fixes) via [Archive.is] Brad Fitzpatrick on Twitter: “lol tear (from )… “:

Install cec-utils

Once everything is installed you should be able to control the tv using the command below:

  • Turn tv on: echo 'on 0' | cec-client -s -d 1
  • Turn tv off: echo 'standby 0' | cec-client -s -d 1
  • Set active source: echo 'as' | cec-client -s -d 1
  • Tv status: echo 'pow 0' | cec-client -s -d 1

Troubleshooting Tips:

  • Make sure your tv supports cec and that it is enabled. Tv manufactures call CEC by different names so you may have to do some research depending on your brand.
  • Make sure you are using a new hdmi cable that is at least HDMI 1.2a

Different names for HDMI CEC

  • Samsung – Anynet+
  • Sony – BRAVIA Link or BRAVIA Sync
  • Sharp – Aquos Link
  • Hitachi – HDMI-CEC
  • AOC – E-link
  • Pioneer – Kuro Link
  • Toshiba – Regza Link or CE-Link
  • Onkyo – RIHD (Remote Interactive over HDMI)
  • LG – SimpLink
  • Panasonic – VIERA Link or HDAVI Control or EZ-Sync
  • Philips – EasyLink
  • Mitsubishi – NetCommand for HDMI
  • Runco International – RuncoLink

Some links on xargs simulation in PowerShell

Posted by jpluimers on 2021/10/13

On nx, I’m used to xargs which allows to convert from a pipe of output into arguments passed to a command. This is useful, as many commands only accept arguments as parameters.

In PowerShell, you can usually avoid an xargs equivalent because commandlet output is a stream of objects that you can post-process using . I for instance used that in PowerShell: recovering from corrupt empty *.nupkg files after a disk was accidentally full during update.

Here are some xargs equivalency examples:

Constructing Suffix Trees: Ukkonen’s algorithm – Wikipedia

Posted by jpluimers on 2021/10/12

For my link archive:

I also need to check out [WayBack] Martin Farach-Colton – Wikipedia, as his algorithm is likely more optimised and more versatile.

Some Windows 10 updates remove registry values; not sure how widely

Posted by jpluimers on 2021/10/12

After watching an autologon system not logging on automatically over the past years, the pattern seems to be that at least major, and some less minor Windows updates remove autlogon parts of the registry.

I’m not sure where the boundary between “major” and “less minor” lies (though I suspect “cumulative updates” and larger), nor if more than these values are affected:

  • key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon"
    • value name AutoAdminLogon gets removed or becomes value 0
    • value DefaultUserName gets removed
    • value DefaultPassword gets removed

This means that now after each startup, I need to schedule a task that runs a script setting the values I need depending if a password is needed or not.

The script also needs credentials, so I need to figure out how to properly do that.

I still need to decide between PowerShell or batch file script, as I already have the batch file from How to turn on automatic logon in Windows and automatic logon in Windows 2003.

For my future reference, some more links on things that can get deleted:

Hopefully these links will help me writing the scripts:

Settling on PowerGUI for PowerShell development

Posted by jpluimers on 2021/10/08

Preparing for another PowerShell article, I found this blast from the past, as somehow this missed the publishing schedule back in 2014!

Original text

After struggling with [Wayback] PowerShell ISE for a while ([Wayback] it started as a proof of concept and wasn’t meant to be an IDE you know) reading [Wayback] Powershell Studio vs Primal Forms Free CE vs PowerShellPlus Pro (also free) – Spiceworks, I’ve started using the free [Wayback] PowerGUI IDE for PowerShell by Dell.

The [Wayback] free PowerGUI used to be maintained by Quest, and after [Wayback] the acquisition of Quest by Dell in 2012, it is still free and is now at Product Support – PowerGUI Pro.

It is great (even got [Wayback] full support for PowerShell 3.0) and you can get it at the [Wayback] PowerGUI Downloads.

Notes:
