MMX Needs New Icons – Are You Willing To Help? – MMX

Posted by jpluimers on 2019/06/30

[WayBack] MMX Needs New Icons – Are You Willing To Help? – MMX:

I am pretty sure all of you already noticed: The current icons in MMX not only look a bit old, they also don’t look well on the Dark Theme. They are not alpha blended and are only available in 16 x 16 pixel size. This may become a problem when the IDE will support High DPI in the future.

Unfortunately the stock icons available in the market simply don’t fit the purpose of most of the individual icons needed, so custom designed icons seem to be mandatory.

I have been asked several times where people can donate to support the development of MMX. While I am still not planning to accept donations for the time I am going to invest in the development, donating for the icons is a good way to show your gratitude. If you are not a able or willing to donate – that’s OK. Anyway, please consider to spread the word about this.

Many thanks to all that already donated and those who are going to do so.

For those still looking for the link to the MoneyPool, here it is: https://www.paypal.com/pools/c/8e4alQxGzA

Grandparents on my mothers side

Posted by jpluimers on 2019/06/29

This is so long ago, at an age so young, I barely had a recollection:

Of the names below, a few passed away too: Sander died when he was very young, Mats 20 years ago, and Frits 15 years ago.

Windows Security From The Ground Up — Decent Security

Posted by jpluimers on 2019/06/28

Because so few people actually make more than 10% of these simple steps: [WayBack] Windows Security From The Ground Up — Decent Security (How to secure a Windows computer).

It starts with BIOS update, configuration, TPM, then secure boot into a bitlocker encrypted drive with a Windows installation that has UAC set to high, and a safe web browsing environment.

ServiceDependencyViewer

Posted by jpluimers on 2019/06/28

Since CodePlex is sunsetting, some archived locations of ServiceDependencyViewer.zip:

It helps you investigate dependencies of Windows Services.

Excel: printing top row on every page, and including grid

Posted by jpluimers on 2019/06/28

I hardly print with Excel, so I always forget these two:

Solid State vs. Electromechanical Relays | Arrow.com

Posted by jpluimers on 2019/06/27

For my reading list: [WayBack] Solid State vs. Electromechanical Relays | Arrow.com

When you need a power switching solution, you are faced with two competing technologies – electromechanical relays and solid state relays. So which is the right choice for your design?

Keywords: SSR versus EMR, SPDT

The Delphi compiler has a hard time coping with circular unit references

Posted by jpluimers on 2019/06/27

In [WayBack] Anyone here with an “F2092 Program or unit ‘?’ recursively uses itself” error in Tokyo? I have this error in Tokyo but the same project compiles ok in Berlin… – Luis Madaleno – Google+, I commented this:

Large circular reference cycles can trip the compiler into emitting this error (next to out-of-memory errors, access violations and internal errors and “unitX.pas F2063 Could not compile used unit ‘unitY.pas'”).

Solution that usually works: quit Delphi, delete .DCU files, start Delphi, build all, then compile. Cumbersome, time consuming, but since the error is intermittent and involves large code bases, it’s was hard to get it to R&D back in the days.

Calculating CRC with a tiny (32 entry) lookup-table | Lentz family blog

Posted by jpluimers on 2019/06/27

For my archive:

I happened to notice that the Arduino OneWire library uses a 256 entry lookup table for its CRC calculations.

I did some research on this topic in 1992-1993, while working on Bulletin Board Systems, FidoNet code and file transfer protocols.

These days memory is not at a premium on most computers, however on Arduino and microcontroller environments it definitely is, and I happen to know that table-lookup CRC can be done using two 16-entry tables!

So I’ve dug up my documentation and code from the time, and applied it to the CRC-8 calculation for the Maxim (Dallas Semiconductor) OneWire bus protocol.

I think this provides a neat trade-off between code size and speed.

License For any of the below code, apply the following license (2-clause “simplified” BSD license), which should suffice for any use. If you do require another license, just ask.

Source: [WayBack/Archive.isCalculating CRC with a tiny (32 entry) lookup-table | Lentz family blog

The example on the page is for the CRC-8 implementation used in the [WayBack] 1-Wire Communication protocol – Wikipedia.

The generator works for CRC-8, CRC-16 and CRC-32 polynomials and can be downloaded here:

Binding git diff to Beyond Compare
