Paint.NET v3.5.11 is now available (via: Paint.NET Blog)

Posted by jpluimers on 2013/08/17

Programmers scale: time versus project completeness

Programmers scale: time versus project completeness

I totally agree that Paint.NET is the best free image and photo editor on Windows.

Writing quality software takes time, not only when writing it in spare time like Rick Brewster does. Getting things “right” is a tedious process and often will set you back: just watch the graph on the right.

So I’m not surprised that it took a very long time after the first Paint.NET 4.0 idea in 2008 to get “close” to a release.

And indeed, it looks like Rick has become much closer which will please many people waiting for Paint .NET 4.

I’m really glad with the announcement that Paint.NET v3.5.11 BETA is now available – Paint.NET Discussion & Questions – Paint.NET Forum.

Edit: while writing this, the final Paint.NET v3.5.11 came out.

It paves the way for Paint .NET 4.0 update in the future, and fixes/improves quite a few things.

A few quotes from it:

This is probably not the update you were expecting I need to push out an update to v3.5 in preparation for the eventual release of v4.0 […] releasing a “beta” today […] I’ll be pushing out the Final/RTM in a few days.

The primary goal of this update is preparing for the v4.0 release: v3.5.10 will not be able to offer the v4.0 update, but v3.5.11 will. […]

Here are the changes for this release:

  • Fixed: The Gaussian Blur effect was incorrectly calculating alpha values for non-opaque pixels. (http://forums.getpaint.net/index.php?/topic/18483-gaussian-blur-mistreats-alpha/)
  • Improved performance of the Sharpen effect by about 25%
  • Improved performance of the Median effect by about 30%
  • Improved performance of the Fragment effect by about 40%
  • Improved performance of the Unfocus effect by about 100%
  • Reduced memory usage when many selection manipulation operations are in the history/undo stack (the undo data is now saved to disk)
  • The built-in updater now supports upgrading to paint.net 4.0 (once it’s available)

There have been rumors floating around that Paint.NET is “dead.” This is not true!

Windows Timer Resolution: Megawatts Wasted (via: Random ASCII)

Posted by jpluimers on 2013/07/11

Don’t increase your Windows Timer Resolution. And keep an eye on programs that do:

Raising the Windows timer frequency is bad. It wastes power and makes your computer slower. Routinely doing this in all sorts of programs that end up sitting idle for hours really needs to stop.

You can use ClockRes to monitor the time resolution and what programs changed it.

Vintage Dave is working on a new multithreaded memory manager for Delphi that does not have a global lock

Posted by jpluimers on 2013/06/19

The comment thread at via The Oracle at Delphi » Give in to the ARC side is very interesting.

So soon after writing a StackOverflow answer on Delphi Memory Managers yesterday, this one by David M (aka vintagedave) caught my eye:

This is unannounced at the moment, but I am working on a new memory manager which does not have a global lock, and is designed for multithreaded usage, including cases where memory is allocated in one thread and freed in another, and many threads are allocating and freeing at once. It also uses a more secure design than FastMM4, which may be important for world-facing code, eg web servers. It’s a personal project which I have not yet announced, but if you are interested (Allen, Guenther, others) please feel free to contact me at vintagedave@gmail.com.

I wonder if it is better than the multithreaded Delphi memory managers I mentioned in the answer:

As a side note:

One of the reasons for using FastMM is the excellent debugging capabilities. It looks like – though not free – DDDebug extends this a lot!

I found it in Wanted: live leak detection for FastMM – DelphiFeeds.com.

ASUS RT N66U did not update DDNS with changed IP addres

Posted by jpluimers on 2013/06/11

Today my router had an IP-address change, but didn’t update the DynDNS.org information in my My Host Services | My Dyn Account. Which meant I could not “phone home”, as I didn’t know the new IP-address**.

Lesson re-learned:

During initial router configuration, watch the router logs, as you might have accidentally updated the DynDNS.org by hand, not by your router

Had this in the ASUS Wireless Router RT-N66U – General Log:

Jun 11 08:01:53 notify_rc : restart_ddns
Jun 11 08:01:53 ddns: clear ddns cache file for server setting change
Jun 11 08:01:53 ddns update: connected to members.dyndns.org (204.13.248.111) on port 80.
Jun 11 08:01:53 ddns update: server output: HTTP/1.1 200 OK^M Date: Tue, 11 Jun 2013 06:01:53 GMT^M Server: Apache^M X-UpdateCode: X^M Content-Length: 7^M Connection: close^M ^M notfqdn
Jun 11 08:01:53 ddns update: malformed hostname: myhostname

The problem: hostname should not only be the name of the host, but the FQDN of the host. Read the rest of this entry »

ThinkPad W701 can have 32GB RAM (via: Google Search)

Posted by jpluimers on 2013/04/11

Earlier this week, I posted abut ThinkPad W701: Win7 Ultimate x64 suddenly only saw 8GB RAM of 16GB (via: [H]ard|Forum).

One of the search results in my query indicated it would be possible to put 32GB in it.

That’s nice, as the official Lenovo ThinkPad W701 specs and Lenovo ThinkPad W701 2500 Overview & Specs – Laptops – CNET Reviews indicate it should max out with 16GB.

This Google search returns lots of results indicating people actually run it with 32GB RAM using 4x8GB memory modules:
