Post February Update

Not too much to say after the Thursday meeting. Small attendance, small topic.

We had a new person show up, so it wasn’t the best night for me to have lost my presentation. I’ve had ghost copies of presentations hang around for ages and not be able to get rid of them. In this case though I fat fingered a response and lost my talk. No recovery, no temp copies, nothing. I tried to recover but I had nothing going for me. I thought I had saved it at least once under the new name, but no such luck. Lost without a trace, so it was a bit of a ramble on the topic rather than an actual presentation. This woule be the one time Powerpoint behaved as it is supposed to do.

Access control headers

I visited the site yesterday and all of the social media icons had turned into hollow squares. I thought that was a little odd, given that it had been working before that so I checked to make sure the fonts were being served. The logs showed that the requests were most assurredly being getting served, so I was left with a new mystery. I really dislike surprises when I have made no changes to something. More investigation required.

OSX and the dd command

In prepartaion for building one of those Raspberry Pi clusters for a demo, I was dumping the raspbian image to a 8GB class 10 SD card on my macbook pro. The write speed was abysmal…

laptop:~ user$ sudo dd if=./2015-11-21-raspbian-jessie.img of=/dev/disk2 bs=1m
Password:

3934257152 bytes transferred in 4278.617339 secs (919516 bytes/sec)
laptop:~ user$ diskutil eject /dev/disk2
laptop:~ user$ 

For those who care, that is roughly 73.5 minutes, to dump just shy of 4 GB of data.

Simple Additions

I was browsing a few pictures a few minutes ago and decided I’d add some pictures for bsdcan 2015 and lisa'15. Literally as simple as tag the photos I want to use, export them to a folder, write an article stub, and then push to production. That has to be the simplest adding of images I’ve done on one of these blog engines yet.

New year, new site

Well, it is 2016 and ovSAGE has been around since the LISA conference of 1998, although the initial announcement was not until December of that year. That makes this group just over 17 years old and while it has never had a lot of members, it has managed to stay alive through a lot of local churn and many meeting places. I was thinking about the various platforms that have been used to manage the group communication over the years. As I remember it, we have used the following:
