shell – How do I grep for multiple patterns with pattern having a pipe character? – Unix & Linux Stack Exchange
Posted by jpluimers on 2020/10/27
Since I keep forgetting this – especially because I cannot remember the “why”: [WayBack] shell – How do I grep for multiple patterns with pattern having a pipe character? – Unix & Linux Stack Exchange by “user unknown“.
The -E means using Regular expression: POSIX extended – Wikipedia.
egrep "foo|bar" *.txtor
grep "foo\|bar" *.txt grep -E "foo|bar" *.txtselectively citing the man page of gnu-grep:
-E, --extended-regexp Interpret PATTERN as an extended regular expression (ERE, see below). (-E is specified by POSIX.) Matching Control -e PATTERN, --regexp=PATTERN Use PATTERN as the pattern. This can be used to specify multiple search patterns, or to protect a pattern beginning with a hyphen (-). (-e is specified by POSIX.)(…)
grep understands two different versions of regular expression syntax: “basic” and “extended.” In GNU grep, there is no difference in available functionality using either syntax. In other implementations, basic regular expressions are less powerful. The following description applies to extended regular expressions; differences for basic regular expressions are summarized afterwards.In the beginning I didn’t read further, so I didn’t recognize the subtle differences:
Basic vs Extended Regular Expressions In basic regular expressions the meta-characters ?, +, {, |, (, and ) lose their special meaning; instead use the backslashed versions \?, \+, \{, \|, \(, and \).I always used egrep and needlessly parens, because I learned from examples. Now I learned something new. :)

delphi – Can I use an Edit Mask to format output? (not just validate input) – Stack Overflow
Posted by jpluimers on 2020/10/27
From a while ago, and – being on the back-end side mostly – I sometimes forget: [WayBack] delphi – Can I use an Edit Mask to format output? (not just validate input) – Stack Overflow
You can use the TField.OnGetText event or TNumericField.DisplayFormat property to modify how the text is being displayed.
Since you have a TStringField holding numbers, you have two choices:
- use a
TNumericFieldand theDisplayFormatproperty- use the
OnGetTextevent and do your own string formattingEdit:
Sam used this approach:
I implemented
OnSetTextandOnGetTextevent handlers. I already had theEdit Mask9999 9999 9999 9999;1;_so theOnSetTextwas justTStringField(Sender).Value := Trim(Text);and
OnGetTextwas justsValue := TStringField(Sender).Value; Text := Format('%s %s %s %s', [Copy(sValue, 1, 4), Copy(sValue, 5, 4), Copy(sValue, 9, 4), Copy(sValue, 13, 4)]);It works fine. Thanks.

Good tips for powering any kind of LED strips from the Adafruit NeoPixel Überguide | Adafruit Learning System
Posted by jpluimers on 2020/10/22
Read these tips before playing with any kind of LED strips: [WayBack] Powering NeoPixels | Adafruit NeoPixel Überguide | Adafruit Learning System.
There are more, but these are the most important:
- When connecting NeoPixels to any live power source or microcontroller, ALWAYS CONNECT GROUND (–) BEFORE ANYTHING ELSE. Conversely, disconnect ground last when separating.
- Adding a 300 to 500 Ohm resistor between your microcontroller’s data pin and the data input on the first NeoPixel can help prevent voltage spikes that might otherwise damage your first pixel. Please add one between your micro and NeoPixel.
- Before connecting a NeoPixel strip to ANY source of power, we very strongly recommend adding a large capacitor (1000 µF, 6.3V or higher) across the + and – terminals. This prevents the initial onrush of current from damaging the pixels.
- Be extremely cautious with bench power supplies. Some — even reputable, well-regarded brands — can produce a large voltage spike when initially switched on, instantly destroying your NeoPixels!
If you use a bench supply, do not connect NeoPixels directly. Turn on the power supply first, let the voltage stabilize, then connect the pixels (GND first).
