Printing, Completing & Scanning PDF Documents

As a contractor I often have to fill in and sign various contract agreements. These are usually tens of pages in length, and while I only have to sign one page, I still must scan in and send back each and every page, even the untouched ones. It would help if a PDF with form filling abilities was supplied, but hey, that’s only rarely the case. This is how I do it. (On Linux – Windows users mileage may vary!)

HP Printer Ink – WTF?

Running a business, I like to keep a small stock of spare printer ink cartridges, so I usually have a couple of spare colour and a couple of black ones, just in case. However, after a recent cartridge change, one black and one colour at the same time, the printer has suddenly stopped working. This was after about a month of perfect usage, not immediately after the change. The printer is an HP Photosmart 2610 All in one – and now, it’s an HP Photo-not-very-smart-at-all 2610 none in one!

Thunderbird – Message Filters stop Working on Email Download – But Work Ok Manually.

I think this topic has the longest title of all my postings! Never mind. Have you ever started Thunderbird fetching your emails, and encountered a pop-up message that starts off by saying “The message could not be filtered for folder ‘whatever’ because writing to folder failed“? Read on for the cure. Continue reading Thunderbird – Message Filters stop Working on Email Download – But Work Ok Manually.

Oracle Proxy Users – What Are They Used For?

This post has also been categorised under “rants and raves” as you will see below! Oracle 10g was the first time that proxy users could be used easily from SQL. Prior to that only Java and/or OCI programs could use them. They’ve been around since 8i, but not (well) documented. Want to know more? Read on….

Transportable Tablespace Migrations with Expdp/Impdp

In the old days of exp/imp doing a Transportable Tablespace export/import was relatively simple – unless you had Spatial data, in which case, it wasn’t. Then we got hold of expdp/impdp and it became “different“. It now seems that in order to do a Transportable Tablespace import with impdp, you don’t tell it to do one! Confused? Continue reading Transportable Tablespace Migrations with Expdp/Impdp

The Dangers of Cheap USB Hubs

As a Raspberry Pi user, I figured I needed a USB hub to allow me to connect stuff (that’s a technical term by the way) to my Pi without overloading the two on board USB ports as these are limited to a maximum of 100 mA each. I purchased a cheap 7 port externally powered hub and it arrived by next day delivery. Continue reading The Dangers of Cheap USB Hubs

The Green Thing

This is doing the rounds on email at the moment, but it made me laugh. Grumpy old sod that I am! 😉

Checking out at the store, the young cashier suggested to the older woman that she should bring her own grocery bags because plastic bags weren’t good for the environment. The woman apologised and explained, “We didn’t have this green thing back in my earlier days.” Continue reading The Green Thing

Can We Have 10g and 11g on the Same Server?

www.pdf24.org    Send article as PDF   

If you install 10g and 11g on the same server, which one do you wish to supply the executables for “oraenv”?

If you install 10g first and allow 11g to overwrite the files in /usr/local/bin when you run “root.sh” then when you eventually call oraenv to set a 10g environment, you get a warning that “$ORACLE_HOME/bin/orabase” cannot be found.

If you allow the 10g files to overwrite the 11g ones, you don’t set ORACLE_BASE. I wonder what problems that might cause?

Cheers.

Removing “Rogue” Expensive Oracle Options After Upgrading to 10.2.0.x.

Install 10.2.0.1 – the base release – of Oracle and deselect the various Enterprise Edition Options – these cost money and we don’t like that, especially if we don’t use them.

Patching to 10.2.0.5 (in my installation – it could be different with previous versions) silently adds OLAP, Data Mining etc back into the mix. Not good – especially if/when Oracle decide to audit your licenses. You pay for what you install whether used or not.
