Delphi Pipe – Delphi related RSS feed running on Yahoo Pipes – via twm’s blog

Posted by jpluimers on 2015/03/28

New Delphi related RSS feed: Delphi Pipe “A collection of Delphi related RSS streams” which works perfectly fine in Feedly.

You can get the source through http://pipes.yahoo.com/delphipipe/thepipe

The source is sooo simple, that I now definitely need to make some time to really do some Yahoo Pipes research:

Since Delphi Feeds doesn’t list my blog any more and generally isn’t very fast in responding to requests for adding or removing feeds, I have created my own aggregated feed: Delphi Pipe. It’s done with Yahoo Pipes and currently contains the following feeds (most important first ;-) ):

Oh and thanks Thomas Mueller for listing my feed second (;

Bug him on G+ to get added.

Later he showed how easy it is to convert your G+ stream to an RSS feed: Using Google+ as input for Yahoo Pipes.

Then how to read a CSV file (which is hosted on his site) as input to the RSS generation.

[NL] Verenigingen Sassenheim moeten bloeden voor (semi-)commerciële bibliotheek van buiten de gemeente – @deteyding @ adestmusica

Posted by jpluimers on 2015/03/28

Bizar: lokale verenigingen moeten bloeden om een (semi-)commerciële Bibliotheek (nauwelijks open is, al tonnen subsidie krijgt en goeddeels buiten de gemeente opereert) te steunen.

Verenigingen zijn de lijm van je samenleving. Ze krijgen al geen of nauwelijks subsidie krijgen en worden hiermee hard geraakt: de huur bedraagt nu al een substantieel deel van hun begroting en gaat zo nog zwaarder drukken.

De Bibliotheek Sassenheim, Bibliotheek Voorhout en Bibliotheek Warmond zijn helemaal geen vereniging (ze vallen onder de stichting Bibliotheek Lisse, wat eigenlijk een commerciële partij is die voor een groot deel buiten de gemeente Teylingen – Lisse, Noordwijk, Noordwijkerhout, Oegstgeest – opereert en nog steeds tonnen subsidie per jaar krijgt).

De zwaarst getroffen verenigingen zijn (huurverhoging per jaar):

  • Adest Musica: 12.350 euro
  • Theater ‘t Onderdak: 8.955 euro
  • Biljart Entree: 3.040 euro
  • ATV Pankras: 2.970 euro
  • De Saksen: 2.470 euro
  • NVVH Vrouwennetwerk: 1.065 euro
  • Crescendo: 1.030 euro

Stichting tot Exploitatie en Beheer van SCC ’t Onderdak (SEBO) moet totaal 31.335 euro extra huur innen. Welzijnskwartier moet 23.650 euro gaan betalen voor Fascinus en @hok. Waarschijnlijk zal er voor beide stichtingen extra subsidie nodig zijn om deze huren te kunnen betalen.

In Agneshove, Het Trefpunt en de Bibliotheek krijgen lagere huren door het gelijktrekken van de huren in de tarievennota. De bibliotheek gaat 26.635 euro minder huur betalen. St.Cecilia is 2600 euro goedkoper uit.

[NL] toch nog onverwacht snel: Eindelijk. Glasvezel in Sassenheim. @deteyding @xs4all @Reggefiber

Posted by jpluimers on 2015/03/28

Toch nog onverwacht snel: Eindelijk. Glasvezel in Sassenheim.

Ik had geen hoop meer dat dit snel zou gebeuren en daarom voor mijn broer xs4all ADSL laten aanleggen:

Mocht je zakelijk op een bedrijventerrein glasvezel willen, dan kan dat op de industrieterreinen Industriekade, Jagtlust en Zuid-Sassenheim. Zie Glasvezel Sassenheim voor meer informatie.

OS X Finder: viewing hidden paths

Posted by jpluimers on 2015/03/27

One of the most frustrating things on a Mac is that the OS X Finder does not allow you to browse all paths.

Unlike Windows the Windows Explorer, where it is fairly easy to switch a preference for enabling/disabling showing the hidden files and folders, there is no option in the Preferences. There is a command-line trick (see below) to enable/disable showing hidden files and folders.

Luckily, both the Windows Explorer and the Mac OS X Finder allow you to specify the full folder path to browse, where you can enter a path that otherwise would (partially) be invisible.

  • Windows Explorer: just enter a full path in the address bar.
  • Mac OS X Finder: press Shift-Command-G (or Menu -> Go -> Go to Folder...), then enter the full path.

An alternative for Mac OS X is the payed (but great tool) Path Finder which is one of the best Finder replacements I know.

.NET threading: native and managed thread IDs do not per se correlate

Posted by jpluimers on 2015/03/26

Next time I run into .NET and native threading issues:

Main UI threads often have a correlation between managed and native thread IDs.

But for other threads, you cannot be really sure.

Some background articles on this:

Quite weird. About 80% of the repos on github have no license…

Posted by jpluimers on 2015/03/25

Reminder to Self (this?) put a LICENSE .txt or LICENSE.md file in all my repos.

It isn’t difficult to choose one:

For new repositories, GitHub even has a license picker.

Thanks Jan Wildeboer for reminding me.

–jeroen

PS: most of the things I put on-line are using a BSD 3-clause “New” or “Revised” License. But I might go for a simpler one. It doesn’t hurt looking at your licenses every now and then.

Interfaces are great, but they can be a pain to debug. Forgetting one weak link can lead to Access Violation hell…

Posted by jpluimers on 2015/03/24

Paul Thornton posted a nice question on G+ two weeks ago:

Interfaces are great, but they can be a pain to debug. Forgetting one weak link can lead to Access Violation hell. I seem to remember a utility that would let you visualise the links between interfaced objects, but can’t remember what it was called. Anybody know?

Do you have any clever interface debugging tips or tricks?

Mixing object and interface references leads to complex situations, especially when some classes make refcounting go away (not limited to UI components) so refactoring is a good idea, it at all possible:

Lars Dybdahl:

Refactor them away :-)

When the mix of interface reference counting and TObject gets so complex, that the source code is no longer obvious, maintenance costs sometimes become too high and another solution might be better.

Nicholas Ring:

 

+Lars Dybdahl Totally agree and it is even worse when reference counting is disabled (like adding an interface reference to an UI component).

 

There is not much tooling, this thread only mentioned RefCountTracer and FastMM:

Steffen Binas:

There is this: https://github.com/AquaSoftGmbH/RefCountTracer

It helps you find memoryleaks, but also could show you if a refcount goes below 0.

Paul Thornton:

This link was very useful. It also points to a good FastMM tutorial.

Which reminded me I totally forgot to post that tutorial on my blog so here it is:

For both FX and DX lenses: printable Nikon lens hood templates – via Nikon Rumors

Posted by jpluimers on 2015/03/23

Since I posted In case I ever misplace/break one: Free printable cardboard lens hoods, I found that Nikon Rumours had covered that too.

Now the added even more coverage in Printable Nikon lens hood templates | Nikon Rumors.

Which is kind of neat as now there are two kinds of printable lens hoods: DX (for my D300) and FX (for my D700).

Home Labs made easier with VSAN 6.0 + USB Disks | virtuallyGhetto

Posted by jpluimers on 2015/03/20

Interesting; steps can be found in Home Labs made easier with VSAN 6.0 + USB Disks | virtuallyGhetto:

Disclaimer: This is not officially supported by VMware and should not be used in Production or evaluation of VSAN, especially when it comes to performance or expected behavior as this is now how the product works. Please use supported hardware found on the VMware VSAN HCL for official testing or evaluations.

For a VSAN home lab, using cheap consumer USB-based disks which you can purchase several TB’s for less than a hundred dollars or so and along with USB 3.0 connectivity is a pretty cost effective way to enhance hardware platforms like the Apple Mac Mini and Intel NUCs.
