Day 6 – Floating

I find technical topics relaxing, and it’s been too long since I have looked into the gaping maw of a handful of venomous formulas. Add to that the fact that this is a topic that I’ve been thinking about turning into a “one page cheat sheet”* with the most important facts summarised, and tonight I tackle…

IEEE 754

Or as their parents call them when they are at home: floating point numbers.

Both the best and the worst thing ever invented to deal with fractional numbers in computing. Providers of so much convenience. Providers of so many lost hairs.

I haven’t done enough research yet to write my one-pager*, but this will be the most interesting part of my day today.

The results of my research can be found at: Floating Point One-Pager (2013-07-28).

* I am availing myself of the web definition of “one page”, meaning that it could literally be any length by the time I am done.

Day 5 – He Sits in Judgement

We all know the Internet likes cat pictures, so here’s me making the most of my day filled with cleaning…

This is my cat Obie, short for Oberon (no, neither are my password, I’m not that security illiterate, thanks). He judges me. A lot.

Today he was sitting back watching me clean and in no uncertain terms telling me that I don’t know what I’m doing, and to stop embarrassing myself already. But he washes with his tongue, so what does he know!?

And because one cat picture is never enough…

Day 4 – My Name Is…

I had a very lazy very boring day today… so prepare to be under-whelmed!

Besides a coffee to start the day around noon, and a lot of time wasted browsing around the Internet, and then some TV to cap off the day, the only thing worth mentioning is that I spent some time looking at sites that do business cards.

Every once in a blue moon I consider getting business cards for my online identity.

What could be more boring than outdated, white card-stock, black lettering in unimaginative fonts, and cliché timid centre-alignment business cards?!

No, not for me either, thanks.

The desire to do something with business cards was probably sparked by a story I read years ago about Steve Wozniak’s awesome metal business cards.

It turns out that there are myriad companies on the web these days that provide interesting options, such as: paper/plastic/wood/metal as base materials, glossy highlights, embossing, metal foil, die-cutting shapes, and more.

The header image has a set of 3-ply wooden business cards by Jukebox Print.

The image just above shows a gold foil lettering detail on card stock by Umax Print.

And the ever-popular Moo Print plan cards with an NFC chip in the near future.

I keep looking at all the options, and wanting to combine all the cool options into a single design against the better judgement of my design instinct. If I ever go through with it I’m sure I’ll manage to tie that demon up and stick to something classy and understated.

In reality my cards do not need to contain a lot.

Just “JerryJvL” will do in fact.

You see, I’ve managed to grab that username on all the major web-based services; on the first 10 pages of Google search results, all but about a dozen refer to me.

What could be better than a business card with nothing more than 8 letters on it?

Day 3 – Seeing RED

Last weekend I saw World War Zee at the cinema. Now, before anyone reads me my own rules, yes, last weekend is well before the 24 hour window I have allowed myself.

Bear with me.

I often do not find the trailers before a movie very convincing one way or another. Scratch that… most often it clarifies a whole bunch of movies I should not go see.

This time I was lucky; there were two good trailers.

First one is for Now You See Me, which looks like a fun cross between Ocean’s Eleven and The Prestige. I cannot say much more about that until I have a chance to actually see it when it is out.

Second one is for RED 2, which my friend immediately recognised as such. He was trying to recommend I watch RED, which I had not seen before, but that soon became a moot point.

DAME HELEN F&*$%NG MIRREN casually dissolving a body in a bathtub while chatting to Bruce Willis. Followed a few shots later by a car chase where she wields double handguns out of opposite sides of a spinning vehicle. I HAVE TO SEE THIS.

Also, I have to see RED!

Which is exactly what I did tonight.

It’s a story of CIA operatives, cowardly Vice Presidents and obvious Villains. Nothing particularly special about the plot, except that it totally doesn’t take itself seriously.

This is an action movie filled with the most improbable moves and gun shots, taken so casually and with a big wink to the audience that there are times it is hard to contain a giggle.

I’m glad I watched this.

Very glad.

And now I’m sad I have to wait till RED 2 is out, because I have to watch that too.

Day 2 – Regali Dolci

I still have the after-effects of Rhino-whatsit-virus, which has now morphed into an annoying cold. It makes my brain feel like cotton wool. Sufficiently so that I headed home early from work to have a lie down.

I probably should not have come in, but my e-mail gets lonely without me.

That could have easily been the most riveting part of my day.

Regali Dolci - Gelato
Regali Dolci – Gelato

Luckily for the blog, there was a birthday for me to sniffle my way through. The local town centre is actually quite pleasant on a Thursday night, with a few pretty decent restaurants on the main road.

So dinner was Tapas.

And dessert was Gelato.

Meaning that the most interesting part of my day today was the consumption of one scoop of Rum & Raisin and one scoop of Hazelnut.

And now, I have a date with a tissue box!

Day 1 – The Most Interesting Thing…

…that Didn’t Happen.

Today I was going to sort some banking in Bondi Junction. I had received a letter from my Dutch bank that my account needed more authentication than was on file.

I can only assume they needed to make sure I wasn’t a terrorist trying to fund crime a few hundred Euros at a time.

You see, when I moved to Australia I kept my Dutch bank account to make it easy for family back home to send me gifts for birthdays, Christmases, and other such occasions. They’d put it into my bank account in Euros and I’d withdraw it down here in Australian Dollars.

Alas, no longer.

Anyway, to get back to the story. They apparently need a certified copy of my passport to continue to allow me to exchange money with my relatives. So I needed to go to the Dutch Embassy in Bondi Junction.

I booked a day of leave.
I drove to the station.
I checked I had all my documents with me…

Passport-Date

I clearly should have checked a little more in advance. After a very brief call to the Embassy this now has become a much more extensive undertaking. And with the urgency gone, I withdrew home to formulate a new plan.

I’m going to investigate whether keeping a Dutch account is still the cheapest approach to handle international transfers. It used to be, but now it just feels like a hassle.

And a good thing I wasn’t planning to travel any time soon.

365

Time to take this blogging thing more seriously (because I say so). Time to set myself a challenge.

I’m going to attempt writing a post every day for the next year. I will take bets on how quickly this will devolve. Please leave your money in the comments.

The rules I will follow (because 365 posts itself is clearly not challenging):

  • Write one post every day, on the day… no writing ahead
  • “On the day”, defined as midnight-to-midnight wherever I happen to be at the time
  • The post will be about the most interesting thing1 of the preceding 24 hours to the best of my ability

I will tag all posts in this series with “365”. If I have some trouble getting started, I reserve the right to start counting 365 days once I get the routine going (no later than August).

What’s in it for you? … who knows…
What’s in it for me? … a blog… and dinner, most definitely a fancy dinner to celebrate. I might even blog it.
