Dual Quad-Core Mac Pro’s Just Around the Corner?
Hardware hacker extraordinaire Anand Lal Shimpi from AnandTech is so influential that Intel sends him engineering samples of their upcoming processors. Anand recently acquired an engineering sample of a quad-core Intel core 2 Xeon CPU, code-name “Cloverton”. The quad-core Cloverton is pin-compatible with the LGA-771 CPU sockets shipping in the current Mac…
New RubyCocoa Release & BridgeSupport
More interesting for MacResearch members may be the new BridgeSupport project, which appears designed to provide better support for scripting bridges to Objective-C, like RubyCocoa and PyObjC, although the project is independent of any scripting language. BridgeSupport files are XML files that describe the API symbols of frameworks or libraries that cannot be…
Matlab benches for Mac
As I posted a few days ago, I would like to generate a small enquiry about MATLAB performance under Mac OS X. Here I post the data from the bench command on my iBook G4 12′ 1.2 Ghz, 1.25 GB RAM. Some of the currently available benchmarks are below. So perhaps those…
Vvidget: Chart and Graphing System for Mac OS X
Often when I’m trying to analyze data access patterns in code I’m optimizing, I find it useful to plot the locations of the data points on 2D (or ideally 3D) grids. A few days ago I was analyzing a complex data access routine and found my normal methods of doing…
ChemAxon
As many know I wrote a GUI for the opensource cheminformatic toolkit Openbabel called iBabel. One of the options is to use the java applet Marvin for structure display and editing. A couple of people have asked me about the availablity of Marvin from ChemAxon so I thought I’d mention they also have a suite of…
A Review of Marvin
ChemAxon are a software company that produce a variety of cheminformatics applications and software development modules. A key driver for development has been maintaining portability among various operating systems and a focus on web-based integration thus they have made extensive use of Java. Many of the tools are free to academics…
EGO, roundtrip and Linkback
There has been considerable discussion on the Cambridgesoft forums about a number of problems for users that have arisen with the upgrades to both the Mac OS X operating system and the latest version of ChemBioDraw. One of the major problems that is that when a structure is pasted into…
Tuning Cocoa Applications Using DTrace: Writing Scripts
One of the great things about developing for the Mac or iPhone is the suite of performance and debugging tools that Apple provides: GDB, Shark, Instruments, etc. However, there’s one tool which has received a lot less attention than it should, potentially because of its perceived complexity. That would be…
Security Memory Performance
With help from a friend, Mark Bellon, I ran a wide variety of tests on several different MacPro configurations. These benchmarks were designed to test the performance of the system on jobs with a large variation in their memory usage. For now, I’m only including plots for the case of…
