I’ve been using EWWW image optimiser to compress all of my JPEG and PNG images on this site for several years. EWWW makes use of OptiPng and PngOut and whilst these are powerful tools there are alternatives out there now that I wanted to test and compare.

Touchpad settings on Sony Vaio VPCSB
My old man has a Sony Vaio VPCSB laptop, a 13.3″ model that is now about 10 years old but thanks to an SSD and extra RAM is still more than adequate for today’s demands. I recently upgraded it to Windows 10, despite no help at all from Sony, and ran into an issue with the touchpad having all the silly Windows 10 swiping and scrolling turned on by default with no obvious way to turn it off.

Sleep and WOL with Intel 82567LM‑3
I have a couple of old USFF Dell Optiplex 760 PCs that have a built-in Intel 82567LM‑3 gigabit ethernet connection. Getting this adapter to work with both Sleep (S3 Suspend to RAM) and WOL (Wake on LAN) has proven very tricky. The PC originally came with Windows Vista and as a business class PC you’d expect these 2 features to work but it has always been a battle to get them working.

The search for a storage server PSU
I recently posted abiout my search for a new storage server case. My next search involves finding a suitable PSU! It seems in recent years it has got much harder to find the type of hardware I like to use, probably because the fashion has been to go smaller and sleeker which is generally more possible in this era of improved performance-per-watt devices. However, if you have space and you want systems to be cool, quiet, and efficient then large is still the way to go.

Fixing wordpress visual editor
I’ve had an issue recently where the wordpress visual editor stopped working. The code editor worked fine, but the visual button just didn’t do anything at all. I knew it wasn’t a server setting because it impacted 2 van 5 wordpress sites on the server, but the others worked fine. I tried deleting and copying fresh copies of “wp-includes” and “wp-admin” in case something had got corrupted but this didn’t resolve the problem either.

The search for a 12 bay 5.25″ full tower case
I have an original CoolerMaster Stacker case (STC-T01-UW) that I use for my server. It is great because it has 12 5.25″ external drive bays. Strictly speaking it has 11 useable as 1 of them is taken up by the power button and front-usb module, but this can be modified if necesary. This spectacular case is great for fitting lots of HDDs for a storage array. My system currently has 10 regular size HDDs and 2 SSDs in it which fit easily with plenty of cooling. As I want to build a second server to migrate the older drives into I am looking for another case with equally impressive capacity…

nginx curves error SSL_CTX_set1_curves_list
I recently ran into an error with a new nginx config that I couldn’t find anywhere on google! Turns out that was because I was reading the font wrongly and substitued a lower case L for a number 1. So if you ended up on this psage because you searched for SSL_CTX_setl_curves_list then try searching again, for SSL_CTX_set1_curves_list.
