When you screw up … make it positive for your users

Yesterday I was caught up in an interesting SNAFU at my local Supermarket.  All of the checkout registers shut down, thus making it impossible to pay for groceries.  Later on Twitter, the company apologized as we discovered it was actually a nationwide outage!

 

TO_DOG_YEAR

Some members of the Oracle community got well and truly into the April Fools Day spirit this year.

There were plenty of very earnest looking blog posts about a new 18c function – “TO_DOG_YEAR”.  You can read their posts here

2017–what grabbed your attention

Here are the blog posts that you hit on most this year.  Thanks for supporting the blog, and always, there will be more content next year !

Buffer cache hit ratio–blast from the past

I was perusing some old content during a hard drive “spring clean” the other day, and I found an old gem from way back in 2001.  A time when the database community were trying to dispel the myth that all database performance issues could be tracked back to,  and solved via, the database buffer cache hit ratio.  Thankfully, much of that folklore has now passed into the realm of fiction, but I remember at the time, as a means of showing how silly some of the claims were, I published a routine that would generate any buffer cache hit ratio you desired.  It just simply ran a query to burn through logical I/O’s (and burn a whole in your CPU!) until the required number of operations bumped up the buffer cache hit ratio to whatever number you liked Smile 

Top Ten Travel hints and Tips

Well, let me be honest right at the top here.  These are not travel hints Smile  These will not help you in any way.

This is me having a whine and a rant about a minority of people that I occasionally encounter when travelling.

Yes, this can probably be best described as me and my first world problems, but I need to expunge these so that next time I travel, I don’t lose my head, and stuff some poor unsuspecting innocent passenger“under the seat in front of me or in the overhead locker” Smile

The village idiot

If you are not familiar with the term Village Idiot, then Wikipedia provides a sufficient definition from which I can base this blog post.

“The village idiot … is a person known for ignorance or stupidity”

Over the past couple of weeks I’ve been flying a bit.  First was OpenWorld and OracleCode in New Delhi in India, and from there, I was heading straight from there to Cleveland, Ohio for the GLOC users conference for the first time.  Being a fairly seasoned traveller, this should have been a relatively straightforward affair.

Well… things didn’t turn out that way. 

Hack-a-Mongo

I was reading an article today about how 10,000+ Mongo installations that are/were openly accessible on the internet have now been captured by ransomware, with nearly 100,000 other instances potentially vulnerable to the same issue.

Now, since I’m an Oracle blogger, you may be inclined to think the post is going to jump on the “bash MongoDB” bandwagon, but it’s not.  I am going to bash  something…but it’s not MongoDB Smile

What you "liked" last year…

Well…when I say “liked”, what I mean is “the stuff you all clicked on a lot” last year. Whether you liked it or not will remain one of those great mysteries Smile
