How did Apollo get to the Moon?

It’s extraordinary that people haven’t been back to the Moon in my lifetime. I can only imagine the excitement of the first Moon landing, although from what I’ve read the later missions the general public wasn’t that interested in it. Still, the Apollo missions were an amazing feat of engineering, science and bravery.

Over the last few days I’ve been listening to two episodes of the Omega Tau Podcast:

Both episodes are interviews with David Woods, author of the book How Apollo Flew to the Moon and full of fascinating detail. They’re well worth a listen.

If you thought flying to the Mun in Kerbal Space Program was hard just wait ’til you hear about everything they accomplished using 1960’s technology. While they did have computer assisted landing procedures when they got to their destination I bet it was no Mechjeb! There is the FASA mod for the game, adding 300 new parts, including a Lunar lander! Here’s a video (and Reddit thread) of it in action, although I’m upset that he left someone on the Mun..

As luck would have it, last night I saw that Ars Technica published 45 years after Apollo 13: Ars looks at what went wrong and why a few days ago. Another interesting read, contrasting what the film “Apollo 13″ showed to reality. Useful and insightful comments too, including more book recommendations. I have plenty of reading ahead of me.

(Thanks to Adam Heckler’s post I found out about Omega Tau, it’s quickly turning out to be one of my favourite podcasts!)

WP Super Cache 1.4.4

WP Super Cache is a full page caching plugin for WordPress. It creates static pages that are served quickly by the web server.

Light Trails in Blarney

Over the weekend there was a flurry of excitement as not one, but two releases of the plugin were made in quick succession. The second to fix a bug introduced in the first. I’m very sorry about that.

WP Super Cache 1.4.3 fixed a security bug in the cache file listing section of the plugin settings page. A carefully crafted query by a third party would cause an XSS in the file listing. While serious, the owner of the blog cannot be tricked into loading the file listing page by way of an image or public link as a nonce is required to load it. The attacker would have to ask the blog owner to visit the cache listing page manually. Thanks to Marc Montpas from Sucuri for reporting that.

WP Super Cache 1.4.4 fixed a bug introduced in the previous version where queries with GET parameters caused a fatal error. Thanks to webaware on the WordPress.org forums for reporting that and including a patch to fix it.

If you’re using an older version of WP Super Cache you’re encourage to upgrade to 1.4.4 as soon as you can.

How’s that separation of church and state going then?

We live in a secular democracy but a few days of the year you’d hardly know it. I don’t count Christmas as that’s really the most consumer driven spendfest of money and consumption ever. Good Friday is one of those days though and it’s made all the more obvious when you go into any shop in Ireland today:

You can’t buy alcoholic drinks today in Ireland, but that’s alright because anyone who cared was out last night at the off-license getting their tins and bottles for the party tonight. There’ll be some sore heads tomorrow!

As the Rubber Bandits so eloquently put it,

Make sure ye don’t drink alcohol today. There was a lad nailed to a cross in the late Iron age and he’s his own father. The two of them will set you on fire after you die if you drink cans. Just to be extra safe; our government, which is comprised of rational adults has written this into the law so you can’t buy cans anyway. It’s grand, don’t worry though. You can eat big chocolate eggs on sunday. This is because the lad who was his own father from the late Iron age didn’t die after all. So you can eat the chocolate eggs then because of that.

Looking forward to Sunday, no lie. Yummy Chocolate.

Sabermod on the Galaxy S II

The ageing Samsung Galaxy S II still has plenty of life in it. It runs Minecraft PE and Terraria perfectly well!

It might be old, but there are still developers hacking at it and releasing firmware upgrades with modern versions of Android. I decided to try this unofficial build of Slimkat i9100 Sabermod. My previous install barfed and half the apps on it disappeared somehow!

Sabermod installed easily. I already had TWRP installed so it was only a matter of installing the various zip files through it. Give it a go if you have this old phone, especially if you’ve never messed around with ROMs and have this phone lying around. The usual caveats apply. YMMV and you might soft-brick your phone.
