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

2009-11-04T17:29:58Z

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.]]> ethernet0.virtualDev = "e1000"

Change NIC name to em0 in your rc.conf.

ifconfig_em0 "inet 192.168.0.2 netmask 255.255.255.0"

Do not forget backup .vmx file before you edit. I don't know why but named gave connection error "named : creating IPv4 interface failed". listen-on option gets rid of the message. Add this in option directive of named.conf.

listen-on { 127.0.0.1; 192.168.100.0/24; };

Note: Use Lightbox2 on area tag

2009-09-08T14:10:18Z

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

2009-08-28T13:35:14Z

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.]]> As Apple announced before its release, Safari renders web page faster. I feel like 3 or 4 times faster than same version on 10.5.

Apple excluded Rosetta , backend program for non MacOSX native application like Carbon based app. You need choose Rosetta on custom install dialog.

Installation succeeded.

New time zone setting corrects clock by your location (IP address).

In sharing setting, sharing scanner option was added. (I wonder if it works correctly with my Canon scanner.)

In language and text setting, you can automatically replace special character.

When you switch input method, floating dialog appears on center of display.

Top command displays more status.

Blue glow frame appears around focused window in expose.

"Screen shot (スクリーンショット)" added to file name of screen shot.

This is just a release of refined upgrade version. So you can not find any impressive feature in this version, but it's only $29 (3300JPY).

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()

2009-05-25T15:20:40Z

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.

FreeBSD ports autoconf-2.62 bug - autoconf-2.62.texi:1723: Unknown command `'.

2009-05-25T15:07:56Z

Errors occured while compiling autoconf-2.62 of FreeBSD ports, "autoconf-2.62.texi:1723: Unknown command `'.". To solve this problem, remove old version of makeinfo from /usr/bin/makeinfo, and install new version of makeinfo by installing textinfo from ports (/usr/ports/print/textinfo).

Avoid Google Wireless Transcoder and redirect to mobile site.

Google mobile lists both PC site and Mobile site in same result list. And its wireless transcoder tries to transcode PC site for mobile device. To avoid it and redirect to mobile site from the URL in search results, just add a link tag in head tag of PC site. Support page on Google (Japanese)

Note: Anchor tag in a box element with clearfix collapses top margin

2009-02-25T14:00:25Z

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

2009-02-25T03:28:39Z

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

Note: FireFox ignores style attribute without getElementById

2009-02-03T05:51:56Z

FireFox ignores style attribute in JavaScript without "document.getElementsById('STYLE')".

Macfusion

2009-01-09T14:23:46Z

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.

2009-01-06T12:59:00Z

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.
