Server Problem : A Resolution?

AWSIt’s been a pretty annoying couple of days on the website server front.

The server locking up intermittently is one thing, and for all I know, maybe my fault? The incompetence of the hosting company is quite something else.

Just so you are aware why I was doing my nut yesterday, the hosting company had disabled my ability to force a power cycle of my dedicated server while they did a hardware test. They forgot to (more...)

VirtualBox 5.0.20

It’s been 10-ish days since VirtualBox 5.0.18 was released and the world is screaming out, “Where is 5.0.20 already? We want to update all out Guest Additions!” Well, it’s here… 🙂

Happy upgrading!

Server Problems : Update

hard-disk-42935_640This is a follow on from my server problems post from yesterday…

Regarding the general issue, misiaq came up with a great suggestion, which was to use watchdog.

Server Problems : Any ideas?

I’m pretty sure last night’s problem was caused by a disk failure in the RAID array. The system is working now, but it might go down sometime today to get the disk replaced. Hopefully they won’t do what they did last time and wipe the bloody lot! 🙂

The subject of this post is not about this specific incident, but more generally about what I’ve experienced over recent weeks/months.

Please be patient!

angry-1300616_640It’s extremely nice to have a big audience. It’s very flattering that people care enough about what I say to be bothered to read it. The problem with having a large audience is people can get a very demanding at times. 🙂

I’ve mentioned the 1% rule (or 1-9-90) before. The number of people producing content in an internet community is really small compared to the number of people consuming it. That discrepancy can cause problems when (more...)

Learning to answer questions for yourself!

notes-514998_640It’s not important that you know the answer. It’s important you how to get the answer!

I’m pretty sure I’ve written this before, but I am constantly surprised by some of the questions that come my way. Not surprised that people don’t know the answer, but surprised they don’t know how to get the answer. The vast majority of the time someone asks me a question that I can’t answer off the top of my head, (more...)
