Java Remote Debugging in the Real World

Troubleshooting a problem on a remote server, especially in production, is not an easy task. Sometimes it involves debugging the application code directly on the server.

A Common Mistake When Caching Nullable Values

Caching is hard in various ways. Whenever you're caching things, you have to at least think of:

In this article, I want to show a flaw that often sneaks into custom cache implementations, making them inefficient for some execution paths. I've encountered this flaw in Eclipse, recently.

Spring Boot Developer Tools and LiveReload

When we develop web applications with Java, we have to restart the server to pick up all our changes. This kills productivity. Spring Boot Developers Tools provides solutions to automatically pick up changes without a complete server restart. Let's get productive with Spring Boot Developer Tools.

The Problem With Server Restarts

When we develop our applications (web or RESTful API), we want to be able to test our changes quickly.

Wally 2.4.3 (Qt Other Utility)

ThumbnailWally 2.4.3
(Qt Other Utility)
Wally is a Qt4 wallpaper changer, using multiple sources like files, folders, FTP remote folders, Flickr, Yahoo!, Panoramio, Ipernity, Photobucket, Buzznet, Picasa, Smugmug, Google, Vladstudio and deviantART images. It runs under Linux, Win32, MacOSX and OS/2, and it's available in many languages.

Supported Window Managers:
- Win32
- MacOSX (using OSA scripts)
- KDE3
- KDE4 (using WallyPlugin)
- Gnome
- GnomeShell
- XFCE4
- Fluxbox
- Blackbox
- FVWM (unstable)
- WindowMaker

If you are upgrading KDE4 to 4.4, you must rebuild from sources, cause WallyPlugin can crash Plasma. DEB files are available for Lucid.


NOTE FOR KUBUNTU!!!!
If you're upgrading to 10.04 Lucid, KDE4 will crash at boot. To recover your system, just do the following steps:

- Press Alt-F2, type "konsole"
- At prompt, type "sudo rm /usr/lib/kde4/plasma_wallpaper_wallyplugin.so"
- Restart your system.
- KDE4 should start normally. Please remove Wally, and download the specific package for Lucid, available below.


Note for Ubuntu users: if you're using KDE4, please use KDE4 ONLY packages!!!

Note for Mac OSX Snow Leopard:
You must disable "Change Picture" feature, that's in System preferences > Desktop & Screen Saver > Change picture.

Note for Windows 2000/XP: Active desktop must be disabled! Right-click on desktop -> Properties -> Customize desktop -> Web -> Uncheck all items you find there

PdfArticle 0.11 (Qt Scientific)

ThumbnailPdfArticle 0.11
(Qt Scientific)
PdfArticle is a pdf viewer for mathematical articles. Its goal is to present for eah page the images of its references, such as bibliographies, theorems and equations.For now it is only available for Linux, due to the dependance of Poppler. A compile version for Windows and/or Mac would be greatly welcome, and also debian and redhat packages :)

You will need the libraries of QtSqlite and of Poppler. More precisely, I have installed :

* libpoppler-qt4-3
* libpoppler-glib4
* libpoppler5

and for compilation :

* libpoppler-qt4-dev
* libpoppler-dev

For sqlite :

* libqt4-sql-sqlite
* libsqlite0
* libsqlite3-0

and the devels :

* libsqlite0-dev
* libsqlite3-dev


changelog:
0.11 :
* UI improvement
* more ways to navigate among articles
* usual bug fixes

0.10 :
* Add a Mandriva package
* Usual Bug fixes
* Add a Debian package (if someone could try it :)
* Creation of several Database Tables, to be use in the future. The aim would be eventually to create a mathematical ontology.

0.9 :
* Several Bug fixes
* Add ToolTips
* Associate urls to authors

LuaJSON C Library - Another Major Revision

A certain David Kolf brought to my attention several failings of my library under his test suite, and I have since fixed them and made some additional improvements to the code, re-writing large portions. Thank you to everyone interested in this library and, like Mr. Kolf, please contact me if you ever would like to show that interest! I am always interested in hearing how I can improve the library.

Ricardo Signes: improving on my little wooden "miniatures"

A few years ago, I wrote about cheap wooden discs as D&D minis, and I've been using them ever since. They do a great job, and cost nearly nothing. For the most part, we've used a few for the PCs, marked with the characters' initials, and the rest for NPCs and enemies, usually marked with numbers.

With D&D 4E, we've tended to have combats with more and more varied enemies. (Minions are wonderful things.) Numbering has become insufficient. It's too hard to remember what numbers are what monster, and to keep initiative order separate from token numbers. In the past, I've colored a few tokens in with the red or green whiteboard markers, and that has been useful. So, this afternoon I found my old paints and painted six sets of five colors. (The black ones I'd already made with sharpies.)

D&D tokens: now in color

I'm not sure what I'll want next: either I'll want five more of each color or I'll want five more colors. More colors will require that I pick up some white paint, while more of those colors will only require that I re-match the secondary colors when mixing. I think I'll wait to see which I end up wanting during real combats.

These colored tokens should work together well with my previous post about using a whiteboard for combat overview. Like-type monsters will get one color, and will all get grouped to one slot on initiative. Last night, for example, the two halfling warriors were red and acted in the same initiative slot. The three halfling minions were unpainted, and acted in another, later slot. Only PCs get their own initiative.

I think that it did a good amount to speed up combat, and that's even when I totally forgot to bring the combat whiteboard (and the character sheets!) with me. Next time, we'll see how it works when it's all brought together.

Dave Cross: Perl Vogue T-Shirts

Is Plack the new Black?In Pisa I gave a lightning talk about Perl Vogue. People enjoyed it and for a while I thought that it might actually turn into a project.

I won't though. It would just take far too much effort. And, besides, a couple of people have pointed out to be that the real Vogue are rather protective of their brand.

So it's not going to happen, I'm afraid. But as a subtle reminder of the ideas behind Perl Vogue I've created some t-shirts containing the article titles from the talk. You can get them from my Spreadshirt shop.
