Not maths as such, more precisely pseudomaths:

endhour == 23
starthour == 7
uploadpayload == 24
dayspermonth == 30

bandwidthused == (( endhour - starthour ) - 1 ) * uploadpayload * dayspermonth

bandwidthused = Oopsie!

Miscalculating the amount of data I was uploading to my web host would have totalled 6 times my monthly bandwidth allowance. As it happens it was lucky I caught it early; the 24MB included an early version of the entire folder contents I expected to upload - off by three times my expectation!

Felling silly.

Fixed? Well, I temporarily stopped the uploads prior to changing the routine to run every 3 hours - which may still exceed the allocation but I'm betting on…

I hope I can figure out how to transfer only changes to my site repo. I'll really need to closely monitor my sh\*t.


During November 2015 I decided to start a daily journal - an activity which soon changed into an almost-daily series of blog posts. During the time since I've noticed a shift in the way I approach social media. I'm not sure I like it.

The blogging exercise quickly morphed into a need to create a test site, added to in parallel to my main 10Centuries blog account. I've also been experimenting with rudimentary self-hosting.

As this has happened I've been neglecting both my blog and those people who comment on the posts. I've not even been keeping up with the shiny new after my initial flurry of (hopefully constructive) fault reporting during the early private beta stage.

So it's time for a rethink.

Sure it may be the time of year at fault; I'm not alone in noticing a realignment of priorities away from social media. But this time around I'm analysing in a bit more depth.


Rather than concentrate on 'self' I think it's time I looked at others' blogs. It's only fair.

I've quite a backlog of posts in my RSS feed reader. Time to read, folks.

If you have a blog of your own please let me know, if I have or if I haven't already got it queued up I'll take a look!



February 29 (Wikipedia) is a date that appears only during years divisible by 4 (with an integer remainder!) - apart from those divisible by 100 (but not 400) no, don't stop reading…

There are a lot of interesting notable dates, people and legal facts mentioned on the Wikipedia page, so it's quite a scroll to get to…

In this modern age Bachelor's Day doesn't retain the same importance it once had. But if you're on the edge of popping the question to the subject of your undying love, it's a heck of a day to do it.

Gloves on standby!


Finally, we have liftoff! A week-and-a-half in, and I've managed to configure a £30 computer and create a functional pair of shell scripts to post blithering idiocy to my test site/blog.

Streamlining it all to improve security, to post only changed files within the site, and to have the computer run connected only to power & the local network are my next goals.



I'm annoyed that it's still not working. My blog post build thing.

This is indeed a test post; thanks for your patience at this time.


I've been asleep, honest! Knowing there would be a solution to my Raspberry Pi automation woes I started to search around 2am.

Google and are pretty handy at this time of night; 'rvm installation not working: "RVM is not a function".

It turns out that all I needed to obviate my need to run the scripts in a login shell was to copy the second line of code from ~/.bash_profile to ~/.bashrc.

Thankyou Haris Krajina!

No, I'm not going to wait up.


Apologies for my absence from everywhere social for the last week. I haz bean programin stuf!!!2!¡

The 2 shell scripts to take my GitHub blog repo and throw it up at my Web host now work. Automagically. I'm amazed!

Next step: think of something to write, post it at GitHub, and see if I'm full of hot air or not.

Currently the most recent post at is 'Engineer', which is preceded by 'Nerdity'.

Midnight UK time should prove something - this post should be up round about that time.


A small number of us wear similar sweaters for work - similar in that they're self-coloured and pleasantly form-fitting. Ok, in my case it's because they've shrunk in the wash... (but that's the subject of a previous, uncomfortable-for-me, blog entry here.)

Yesterday a slightly awkward exchange occurred at the coffee machine, one which I felt an urge to follow up by email. I'd had a brilliant idea - a Eureka moment (but without the nudity and attendant spillages.) Here's the brief exchange:

"As an engineer I’m bound by a code of professional conduct to suggest a solution to the jumper hue issue; a daily palette based on the colours of the rainbow. In ascending frequency order, and by day.
> Unfortunately though, my purple one today falls outside the rigid boundaries of the, it must be said, unfortunately limited scheme. Your flagrant Thursday jumper today merits a red card I’m afraid, though I’m sure you could carry the visible spectrum off better than I were you to try harder.
> I’d better start work on version 2.0.
> Baz."

The reply came a little later. I'd honestly not expected one.

"Hi Barrie,
> Thank you so much for your email. Well, what can I say? I’m disappointed with myself that I have got off to a bad start on the first day of the week, but I do feel that I need to correct you on something. Your jumper hue is not purple. I do believe it’s a wine/beetroot shade, but definitely not purple.
> Whilst I appreciate and do accept the card, I can’t accept a red one. Red is just not my colour. I don’t do red and that’s that. Red is not good for us gingers, I’m afraid and as I am too bound by a professional code of conduct as a ginger, you will simply have to come up with another colour.
> I eagerly await your palette…
> Have a nice day,"

Me, speechless, though not apoplectically-so:

"\Baz stills sense of outrage, stands^H^H^H^H^H^H sits corrected, starts work on v2.0.1\"

The conciliatory response came an agonising-for-me 50 minutes later:

"I must say that the beetroot/wine colour does suit you though. A warm colour for these Wintery times. I would even go as far to say that it’s perhaps a burgundy. There’s not many who can carry such a shade off."

Awesome. And, with that, order in my universe was restored.

Which was nice.


Another short one today; it's been a 'nothing' weekend outside my ongoing Raspberry Pi playtime.

Here's a repeat link to what I wanted to do with it, what I've done, and what I've actually accomplished so far - which is actually now 2/3 of the total.

My Raspberry Pi Setup - at

So, what else have I accomplished?

  • Walked Ruby dog,
  • Helped with the girls' homework,
  • Bought a pair of walking shoes to replace those that Ruby chomped,
  • Washed, dried, put away clothes,
  • Changed the cat litter,
  • Been shown a paint colour chart; my wife's chosen a new colour for the hallway…

In-short, underperformed.


A short one today. My nearly-week-old Raspberry Pi is now behaving, more-or-less.\* Here's a link to what I wanted to do, what I've done, and what I've actually accomplished so far.

My Raspberry Pi Setup - at

It's not overly-technical, nor is it particularly helpful or comprehensive. The plan is to expand a bit, make it more readable.

There are spelling errors sprinkled throughout, and it's an early draft.

\*After 4 complete resets to factory settings I'd be silly to admit I've not learned a damn thing about Linux.
