How do I make the first letter of a string uppercase in JavaScript? – Stack Overflow

Posted by jpluimers on 2017/10/11

I’m a JavaScript n00b, so I like solutions like these:

Another solution:

function capitalizeFirstLetter(string) {
    return string.charAt(0).toUpperCase() + string.slice(1);
}

You could also add it to the String.prototype so you could chain it with other methods:

String.prototype.capitalizeFirstLetter = function() {
    return this.charAt(0).toUpperCase() + this.slice(1);
}

and use it like this:

'string'.capitalizeFirstLetter() // String

Thanks [WayBackHutch Moore and [WayBackDeviljho for answering at [WayBackHow do I make the first letter of a string uppercase in JavaScript? – Stack Overflow!

Note you can do it in CSS too as explained by [WayBacksam6ber:

In CSS:

p:first-letter {
    text-transform:capitalize;
}

`Inc(I)` versus `I := I + 1;` in Delphi – they’re the same, but not atomic per se.

Posted by jpluimers on 2017/10/10

Given a variable I: Integer, some people like Inc(I); others like I := I + 1;.

You might think that part of that discussion nowadays should be multithreading.

In practice this does not matter: the compiler will use the same instructions for both statements.

TL;DR: This might make you think they are always atomic. But that’s not always true, as the below differences show. In addition, it can also depend on your processor archicture.

In the Win32 Delphi Compiler, this is how they look:

Script job killer – MikroTik RouterOS

Posted by jpluimers on 2017/10/09

After reading [WayBackScript job killer – MikroTik RouterOS I put lines like these into a few of my frequently running scripts:

/system script environment get systemScriptJobCountTypeIsCommand
:global systemScriptJobCountTypeIsCommand

:local scriptsOfTypeCommandCount [$systemScriptJobCountTypeIsCommand];

:if ($scriptsOfTypeCommandCount > 4) do={
  $outputError value=("$scriptName; too many runnings commands ($scriptsOfTypeCommandCount); bailing out early");
  :return -1;
}

They in turn use this underlying function:

:local scriptName "Function.systemScriptJobCountTypeIsCommand.rsc"
/system script environment remove [ find where name="systemScriptJobCountTypeIsCommand" ];

:global systemScriptJobCountTypeIsCommand do={
  :local result [:len [/system script job find where type=command]];
#  :put "result=$result"
  :return $result;
}

## Example:
## /import scripts/Function.systemScriptJobCountTypeIsCommand.rsc
## :put [$systemScriptJobCountTypeIsCommand];

Comparison of Common markup for Markdown and reStructuredText · GitHub

Posted by jpluimers on 2017/10/09

This is a very good comparison of how to use reStructuredText and Markdown well for rendering at GitHub: [WayBackCommon markup for Markdown and reStructuredText · GitHub.

It is being updated by Alex Dupuy over time at https://gist.github.com/dupuy/1855764 and has two sections:

And it refers to http://pandoc.org/try/ which I had missed when starting with reStructuredText a long time ago.

Examples in there are actually more useful to me than these reStructuredText ones:

It’s about world Cassette Store Day…

Posted by jpluimers on 2017/10/08

The Compact Cassette has been on a comeback path for a few years now and around this time of the year, I expect the [WayBack] Cassette Store Day to happen (check out https://www.facebook.com/CassetteStoreDay/ for the exact date).

So it’s time to re-share the The Daily Drawing by Lorie Ransom on the right.

15 Useful ‘sed’ Command Tips and Tricks for Daily Linux System Administration Tasks

Posted by jpluimers on 2017/10/06

In this article we will review sed, the well-known stream editor, and share 15 tips to use it in order to accomplish the goals mentioned earlier, and more.

I like it because 15 Useful ‘sed’ Command Tips and Tricks for Daily Linux System Administration Tasks has a lot of screenshots showing what each expression actually does.

AI in Voice Assistants: I’m not impressed

Posted by jpluimers on 2017/10/06

I started thinking about writing this post way before [WayBack] When +Google Assistant gets a mind of their own… – Jeroen Wiert Pluimers – Google+.

Though I’ll focus on Google Assistant, the competition (Alexa, Cortana, Siri) have about the same level of incompetence.

Though living in The Netherlands, I use the English version of Google Assistant as it won’t be available in the foreseeable future: [WayBack] Google Assistant in het Nederlands voorlopig toekomstmuziek.

This means that I cannot use Dutch words for destinations, but find English ones.

  • This fails: navigate to Schiphol trainstation
  • This works: navigate to Amsterdam Airport Arrivals

The odd thing is that after switching phones, the latter wants to perform this navigation by public traffic, whereas my former phone it would default to navigation for driving by car.

Basically the only interactions that work sort of OK are calling persons and navigating to places.

Appointments

  • what's my next appointment succeeds
  • what's my current appointment (in case you are late, for instance because of traffic conditions) fails

Calling persons

This allows for aliases to persons like my wife, my brother and my mother. But often it:

  • forgets about an alias asking who that alias is for
  • asks for confirmation of an alias
  • totally misses the alias (so when asking to call my wife mobile, it sometimes presents search results, for instance on “How to spy on my wife’s calls tracking for free”)

After defining these aliases, these actions usually work OK:

  • call my brother mobile
  • call my mother at home

Navigation to places

Contrary to calling, where you can define many aliases, you can only define 2 navigation aliases: home and work. Which means these all fail:

  • navigate to my brother at work
  • navigate to my mother at home

Heck, even the simple variations fail:

  • navigate to my brother
  • navigate to my mother

A cool feature would be navigate to my next appointment, but that fails too. No surprise though, as the simpler navigation commands fail.

The best way I found to navigate is to – just before you leave – search on Google Maps in your browser for the route, then open Navigation on your phone (this presumes they use the same account).

Also, since switching phones, I have to indicate how I want to navigate:

  • navigate home by car
  • navigate to Amsterdam Airport Arrivals by car

Stuff that hardly works

Starting applications is a pain.

Examples that work

  • start pokemon go

These work unreliably:

  • start navigation sometimes opens the map, but at other times asks where to navigate to

These fail at all:

  • start dialer (opens a Google search, but fails to start the stock Android Dialer App)
  • start ex-dialer (my dialer of choice: ExDialer)
  • start player FM (fails to locate Player.FM)

Conclusion so far

It is far from intuitive what kinds of phrases will work, sometimes work or will fail.

I could do a search for how to better phrase my requests, but average users won’t

The Google Voice Assistant still has a long way to go to become useable.

nojhan/liquidprompt: A full-featured & carefully designed adaptive prompt for Bash & Zsh

Wow: nojhan/liquidprompt: A full-featured & carefully designed adaptive prompt for Bash & Zsh

This is really useful!

Sort of tanslated from the first “via” (note that “mit Alles und Scharf” is hard to translate; it’s somewhere between “everything but the kitchen sink, but done right” and “right on the money”):

Bash Prompt Overkill: https://github.com/nojhan/liquidprompt is a Bash “Prompt doing it all right”-extension, which doesn’t care how much any feature costs as we have cores, gigabytes and SSD.

Liquid Prompt automagically recognises context and enables a plethora of features in the prompt when needed based on that context.

It’s like pixie dust for your prompt.

You can configure everything, but you don’t have to: the out of the box experience is already like pixie dust for your prompt.

It works on OS X too and is part of homebrew:

$ brew install liquidprompt

==> Downloading from https://codeload.github.com/nojhan/liquidprompt/tar.gz/v_1.11
######################################################################## 100.0%
==> Caveats
Add the following lines to your bash or zsh config (e.g. ~/.bash_profile):
  if [ -f /usr/local/share/liquidprompt ]; then
    . /usr/local/share/liquidprompt
  fi
If you'd like to reconfigure options, you may do so in ~/.liquidpromptrc.
A sample file you may copy and modify has been installed to
  /usr/local/share/liquidpromptrc-dist
Don't modify the PROMPT_COMMAND variable elsewhere in your shell config;
that will break things.
