Freezing Eclipse 3.7 for Mac

Problem:
Eclipse 3.7 under Mac regularly, but not very deterministic, freezes (stops responding and the only way to communicate with him is by 'Force Quit').
On this occasion, written a few still have not closed critical bugs in eclipseuml Basile, senior for more than six months.
Restarted Eclipse a dozen times a day not very exciting, so I had to be concerned with finding a solution, and I want to share with you, but at the same time and some techniques of its search.


Given:
Eclipse IDE for Java Developers + Eclipse Plug-in Development Environment + Google Plugin for Eclipse 3.7 + Subversive SVN Connectors + more on the little things.
In my case, it most often freezes on save (turn off Save actions could not).
At first sinned on GWT plugin — too much NPE was in the log. Colleagues using linux or windows such problems do not arise.

A standard step in the study of the causes of the problem: using jconsole to see what is happening with the application.
To do this, start Eclipse in debug mode (eclipse -debug) and then connect to EclipseCon the process using jconsole (jconsole and choose start process your Eclipse).

It was not enough: at a time when the app hangs, with jconsole reported that the JVM is not responding.
In this case try to collect information on the application until it meets, in the hope that we will be able to fix a dying condition. For this purpose you can use the following script: there you can find a lot of ideas on search deadlock's.
As indicated, the script has been tested under linux, but under Mac om it also works fine.
Every second the script saves to disk the list of stack trac's for all java processes in the application.

The next step: an analysis of suicide notes.
In my case I found two the following job:

As you can see, one of them tried to refresh decorators. Hence the idea of solving the problem and not disable if we Label Decorator's for SVN?
To do this go into Preferences->General->Apperance->Label Decorations SVN and disable.
The solution is not super, but it works. As a result, without Synchronization view do not understand that committing is necessary and what is not; however, it seemed to me a lesser evil than a regular restart Eclips'.

The use of Lisp in production

Изображение
Grammarly the heart of our business — Central language features — written in Common Lisp. Now the engine handles more than a thousand sentences per second, massturbate horizontally and reliably serves us in production for almost 3 years. We have noticed that there are almost no posts about the deployment of Lisp software in a modern cloud infrastructure, so we decided to share our experiences is a good idea. Runtime and programming environment of Lisp provides several unique, a bit unusual, capabilities to support production systems (for the impatient — they are described in the last part). Wut Lisp?!! Contrary to popular opinion, Lisp is incredibly practical for production systems. Just put, around us, many Lisp systems: when you are looking for air ticket on Hipmunk or riding the subway in London, used a Lisp program. Our Lisp-conceptual services represent a classic AI app that operates on a huge pile of knowledge created by linguists and researchers. Its main us...

FreeBSD + PostgreSQL: tuning the database server

Hello, Charcoaldust! Probably, my article will be of no interest hardened sysadmin and copy-paste seem. But I'm addressing it to those who, like me, being the only developer for the first time faced with the need also to administrate the server, thus solving the problem of highly loaded database. And to Google you are not cursed, try to gather in one place the basic techniques for acceleration of the database server, which I have successfully managed to implement. The input data my problem is the following: dual processor (Intel Xeon) machine, 8 hard drives at 500GB and 12Gb of RAM. And complete, including physical, access to this good. Task: to arrange a fast database server based on FreeBSD and PostgreSQL. 1. RAID The correct partitioning of the available hard drives on raids we need to be PostgreSQL, as tablespacing (more on this below). Your 8 hard I broke into pairs and organized in this way: two pairs unite in RAID1 and two pairs in RAID0 (actually, for our...

As we did a free Noodle for iOS and how we plan to earn

Изображение
Since the beginning of this year we with friends make known multiplayer word game for iOS – Balda Online . For those who have not played the Noodle: the game is played on a field of 5x5. There is a start word of 5 letters. Players in turn add one letter, until the end of the cell. The course is given 2 minutes. The longer the words the more points. In the game important qualities such as erudition, quickness of mind, memory, composure and calculation. We have set ourselves the task to make the world's best Noodle and strive to achieve this goal, constantly introducing new and new features. The interest in the game is big enough: Baldev is playing Online 12 thousand people every day (up to 1000 players simultaneously at peak time), daily spending more than 25 thousand games. We are confident that we will be able to increase these figures significantly. By the way, information about the current number of players is displayed right on the main page. Download game to s...
