The fireplace yule Log visualiser in Google Play Music works, but only from web-browser, not from app

Posted by jpluimers on 2017/12/25

Kristian Köhntopp:

Dear Lazyweb, years ago I turned on the Yule log visualiser in GPMAA, Settings, Labs. Current Google music has no Labs. So how do I turn on cover art?

…

Turns out, the Settings -> Labs switch exists in Desktop Google Music only, and does not (longer) exist in the App.

Sad.

htop – an interactive process viewer for Unix

Posted by jpluimers on 2017/12/25

Great tool: [WayBack] htop – an interactive process viewer for Unix because it’s both interactive and supports a wide range of OSes: Linux, FreeBSD, OpenBSD and Mac OS X.

Thanks to Warren Postma who suggested it in his comment at [WayBack] 18 Useful Commands to Get Hardware Information on Linux – Linuxslaves.

Note that on OS X you get this warning after brew install htop :

htop requires root privileges to correctly display all running processes,
so you will need to run `sudo htop`.
You should be certain that you trust any software you grant root privileges.

On Linux you don’t get this message as there you have the /proc file system providing enough information as explained at [WayBack] osx – Why does htop on Mac OS X require root privileges to see data for all processes, but on Linux it runs without root – Super User.

A workaround (involving the setuid bit) is at [WayBack] Running htop on Mac OS X needs root. Why?! | Blog | JoeNyland.me or by running visudo ensuring you don’t need a password for it at [WayBack] osx – htop isn’t returning CPU or memory usage!? – Super User

hardware rec – When to stop using a hard drive? What rules/software apply? – Super User

Posted by jpluimers on 2017/12/22

A kind of repeat of a 6 year old post, as by now this has much more information: [WayBack] hardware rec – When to stop using a hard drive? What rules/software apply? – Super User.

It is a continuation for another drive of my 2011 post hard drive – When to stop using a HDD? What rules/software apply?.

Basically I was unlucky receiving a brand new drive that appeared exceptionally slow and doing some ticking.

So I ran these on it:

CPU FAN header is called FANA on SuperMicro X10SRI-F and X10SL7-F – Onboard LSI

Posted by jpluimers on 2017/12/22

The SuperMicro X10SRI-F and X10SL7-F boards are very similar, so I was happy that [WayBack] SuperMicro X10SL7-F – Onboard LSI pointed out where the CPU fan was: it’s header FANA which isn’t exactly clear form the X10SRI-F motherboard PDF manual [WayBack]:

FANA is the CPU fan connector

 I never realized that. What is this based on? The manual seemed to be silent about this.

(I connected my CPU fan to the closest fan connector and everything works like a charm, but I’m still curious).

 The manual is indeed pretty much silent, although it does IMPLY that FanA is for the CPU.   It shows “FAN1-FAN4,FANA” and then says “System/CPU fan headers”.   You can read this as 5 fan headers that are the system and CPU fan headers; or as 4 headers and one more that are the system fan headers and the CPU fan header.

WayBack throwing “Wayback Exception An unknown exception has occurred. Unexpected Error” usually indicates a cookie problem

Posted by jpluimers on 2017/12/22

If saving a web-page on the WayBack machine throws you this error on any site:

Wayback Exception

 

An unknown exception has occurred. Unexpected Error

Then usually the cause is having too many cookies.

Clean your cookies for web.archive.org, then try again.

QCScraper ClientDataSet XML dump results – archive of qc.embarcadero.com

Posted by jpluimers on 2017/12/21

Since I’m pressed for time, but didn’t want to wait until putting the dumps on-line, below is a rendering of my gist QCScaper ClientDataSet XML dump results – README.md.

Wishing everybody a great holiday season!

This gist contains two QCScaper XML dumps of the http://qc.embarcadero.com content taken a few days after it came up.

There are four files: two files per dump (both in plain downloaded format as well as formatted with tidy -xml -utf8 for easier comparison, for instance with Beyond Compare).

Each file is compressed uzing 7-zip as the original files would each exceed the 100 megabyte gist size limit; please see https://developer.github.com/v3/gists/#truncation

There are slight differences because of the internal QC architecture, which you can for instance see in issue #7788

Hopefully I will find some time later to blog about this in a better way.

Reminder to self – proposals for Delphi Language Enhancements, a year later

Posted by jpluimers on 2017/12/21

About a year ago, Vincent Parret proposed many [WayBack] Delphi Language Enhancements that a lot of developers feel long overdue.

It sprouted a nice G+ discussion at [WayBack] Blogged – Delphi Language Enhancements – Vincent Parrett – Google+

Now this post is a reminder for myself to check out how Idera lived up to the promises they made in that thread.

Evaluation time…

I just found out that Vincent beat me a few days before I scheduled my post (I wrote my post about a year ago): [WayBack] Just over a year ago, I wrote a blog post where I listed some ideas for enhancing the Delphi language… – Vincent Parrett – Google+

Recommended reading.

Oh BTW: in that thread there was a cool way simulating interface helpers by hardcasting an interface to a record having only one field typed as the interface:

[WayBack] [Delphi] Interface helper proposal – Pastebin.com. By Stefan Glienke. Who else (:

In addition, Allen Bauer chimed in with some great insights.

Finally Document Insight author [WayBack] Baoquan Zuo – G+ posted with more suggestions:

I would suggest Embt consider introducing standard function NameOf and interface helper. These two features will fundamentally changes a lot of things with “minimum” cost.

His thread too has some really nice comments.

Another case against FreeAndNil

Posted by jpluimers on 2017/12/21

I started this post as “A case against FreeAndNil” but soon found out about [WayBack/Archive.is] A case against FreeAndNil – Community Blogs – Embarcadero Community.

Recently I was refactoring a bunch of code that was classed based to become interface based.

The old code had a lot of references to classes like this:

FMyField: TMyClass;

The compiler had detected those as compiler errors so now they were like this:

FMyField: IMyInterface;

But the compiler would still happily compile code (for instance in destructors) containing:

FreeAndNil(FMyField);

The only way that FreeAndNil can be implemented is with an untyped var parameter:
