VMware Fusion error "lnc0: Missed packet -- no receive buffer'

Thu, 05 Nov 2009 02:29:58 +0900

An error of FreeBSD on VMware Fusion "lnc0: Missed packet -- no receive buffer" was sometimes annoying me. When bunch of this error stacks, virtual machine stacks too.After upgrading Fusion 3, it seems to run more stable, but this error still occurs. I had been looking for solution to resolve this problem for several months and I found two solutions. The one is installing VMware tools and using vmxnet for Network interface, and another is editing .vmx file and add alternate NIC statement (e1000) in it. VMware tools for fusion supports ony FreeBSD 6.3 and 7.0. Unfortunatelly I am using 6.2, so my environment was rejected by its installer. I decieded to change NIC to e1000, and as a result it runs without problems.

Note: Use Lightbox2 on area tag

Lightobox2 can't work on area tag as default. To solve this problem, it needs replace imageLink.rel with Element.readAttribute($(imageLink),"rel") in prototype.js. Detail: insert the line below in line 194. if (!target.rel) target.rel=Element.readAttribute($(target), "rel"); Quote from discussion in Pat &Alex Blogging.

Snow Leopard report

Fri, 28 Aug 2009 22:35:14 +0900

Apple released MacOSX new version 10.6, code name "Snow Leopard". Refined 64bit support and Grand Central Dispatch apparently make user experience faster than ever. It is worth to upgrade if you use 64bit cpu. Even if your CPU is core solo or core duo, it is better to install Snow Leopard.

Note: rsync --delete deletes all data when it builds first index.

I did forget that rsync with --delete option deleted data in the backup directory while rsync is building first index. After I reconstructed my backup RAID on the server in my local network, I executed rsync --delete then it deleted all backup data. It was too late when I was aware of it. It is better to do it with --dry-run when you rsync at first time.

Fatal error: Call to undefined function: preg_match()

Tue, 26 May 2009 00:20:40 +0900

After installing php5 from ports, php error said "preg_match" was undefined. This is because I forgot check install option "PCRE" while making port. Just make clean, rmconfig, and reinstall with PCRE, then restart Apache.

Anchor tags which link to the part of its page placed inside of a box element with clearfix collapse top margin of the box element. You need clear floated objects after the box element. Anyone knows alternate way of clearfix?

Note: FireFox ignores percent in size attribute of Flash

Wed, 25 Feb 2009 12:28:39 +0900

FireFox ignores the size of Flash if it is set by percent. FireFox renders HTML strictly based on Doctype when Doctype is HTML 4.0, XHTML 1.0 or later version. I had to code HTML with this type of Flash that other person made, and faced this problem. I didn't know this old issue. The solution is adding size 100% for parent elements.

You also need add elements outside of Flash tags. You can see a description about this issue on Adobe Developer Connection page. http://www.adobe.com/cfusion/communityengine/index.cfm?event=showdetails&postId=3644&productId=1&loc=ja

Macfusion

Fri, 09 Jan 2009 23:23:46 +0900

Macfusion is an application which can mount volumes via FTP or SSH based on MacFUSE program. Though I know this application released few years ago, I didn't trust its stability and had not tried it since its release. Mac OS X can mount FTP as default, but for some reason I can't understand, upload is not allowed. Latest version of Macfusion runs smooth and enables accessing to FTP volumes from finder seamlessly. You do not need run other FTP application each time you upload files to your site.

Note:Apache2.1.11+php4.4.x makes processes stacked.

Tue, 06 Jan 2009 21:59:00 +0900

Apache2.1.11+php4.4.9 (on FreeBSD6.2) makes httpd processes stacked, and they are going to be dumb. The problem was fixed by upgrading php to the version 5.2.8.
