Ember smart mug – is it worth it? Review

Grey ember mug full of tea on a desk

I am notoriously difficult to buy gifts for, and it’s something that my husband mentions regularly as I don’t really need anything, and I have all the computing, gaming and Lego I want1. This year he approached my birthday grinning that he had found me the prefect present… and he really had.

Journal29 puzzle book – review

The original 1985 cover.

It will come as no surprise to anyone who has read any of my other posts that I loved puzzle books as child. I started with the Usbourne puzzle adventure series – cartoon books with clues on each page either in the pictures or what was said. I think my favourite was “Escape from Blood Castle“, which I got as a Christmas present in 1985. It was a perfect mix of slightly creepy and logical deduction that really appealed to me and I loved having new books from this series as they were published.

I quickly moved on to more text based mysteries – particularly the Hawkeye Collins and Amy Adams sleuth series. These were typical kids solve the mystery books. Unlike the Usbourne puzzle solvers, each mystery was stand alone and the answers were in the back of the book in mirror writing. At that age I didn’t have a small pocket mirror so taught myself how to read backwards to check my answers1. After that, it was whatever puzzles I could get may hands on.

STEM toy review: hydraulic robot arm

While it’s no secret I love Lego and tech in general, I also love the educational STEM toys that are released. Sometimes, the ages on the toys don’t always make sense for their complexity, leaving a child who is either frustrated at something too tricky or too simplistic. Both can leave a young person slightly disengaged with STEM, the exact opposite of the idea of these toys!

Robot Arm DIY kit, suitable for ages 10 and up.

Christmas 2019 I was given this Hydraulic Robot Arm kit, suitable for ages 10+1. With work, OU study and general life I’ve only just got around to building it2. So, let’s take a look – is it suitable for ages 10 and up for both build and principles it teaches?

Review: Lego Ideas International Space Station

For the past two weeks I have, like most people, been working from home. Doing fun stuff just for yourself during this time can be incredibly important, and with this in mind I’ve started going through some of the Lego and other building kits I’ve got and just not had time to open. The first of these that I’ve tackled is this years Ideas (fan-designed) Lego set the international space station.

The unopened box.

Review: Oxenfree

Your Oxenfree blue-haired alter-ego, Alex

It’s not often I get chance to play computer games anymore. The precious few hours I get to myself most days are usually filled with trying to catch up on my OU study1. So when I do choose a game, it has to be something immersive, where I make a difference. I loved Fable when it first came out and having finished Fable 3 recently (well behind the rest of the community I know!) I was looking for something new. A game I could play for ten minutes or an hour, something that I could be absorbed into and something where it didn’t matter if I didn’t play it for a couple of weeks. My wonderful husband bought Oxenfree for me on the XBox (also available on Steam) and I was hooked from the beginning. Continue reading Review: Oxenfree

Cozmo – a good present?

One of the toys that’s been advertised heavily in the UK this year for Christmas has been Cozmo with it’s “Big Brain, Bigger Personality” strapline. I got one last year and it was a great present. Let’s get this out there. Cozmo is relatively expensive. For about £1501 there are a lot of other things you might prefer to buy for a child (or an adult) for what is, on the surface “just a toy”. If you treat it as such then maybe it’s not the right thing for you, but viewing Cozmo as a simple toy is far less than he deserves. He is a lot of fun to play with, and the more you play with him, the more he begins to do. Continue reading Cozmo – a good present?

Review: Q is for Quantum by Terry Rudolph

Cover of Q is for QuantumOne of the modules I’m considering for level 3 of my OU maths degree is the quantum world. I recall my A-Level chemistry teacher trying to explain that electrons weren’t solid balls orbiting an atom but rather a probability cloud of where the electron could be. I read a lot of popular science books at the time but found that there was a huge gap between the very high level “here’s a thing, it’s really cool” and “here’s a thing and after 3 pages we’ll dive into complex theory that you’ve never encountered”. Hence when I heard that a new introductory book on the principles of quantum theory had been written specifically for inquisitive young people to help them decide if they wanted to learn the maths needed to take it further, I thought “this sounds like a book 16 year old me would have wanted to read” and I bought a copy for the kindle.

Citation Needed – without it you have opinion not facts

Heckle every speech like this 🙂 Courtesy of XKCD

Throughout my academic career one thing that was repeatedly enforced was that if you were claiming something to be true in a paper, you needed to show results to prove it or cite a credible source that had those results.  It took a lot of effort in those pre-Google Scholar and pre-Arxiv days1.  Reading the journals, being aware of retractions and clarifications and building the evidence to support your own work took time2.  Writing up my thesis was painful solely because of finding the right references for things that were “known”.  I had several excellent reviewers who sent me back copies of my thesis with “citation needed” where I’d stated things as facts without a reference.  My tutor at Oxford was very clear on this: without a citation, it’s your opinion not a fact.

Choosing a Laptop for Deep Learning Development

Confusion matrix
The matrix, well a matrix… A confusion matrix for a 60 class network running on the Dell XPS laptop

If you’re starting out in deep learning and would prefer a laptop over a desktop, basic research will lead you to a whole host of blogs, Q&A sites and opinions that basically amount to “don’t do it” and to get a desktop or remote into a server instead.  However, if you want a laptop, whether this is for college, conferences or even because you have a job where you can work from anywhere, then there are plenty of options available to you.  Here I’ll lay out what I chose and why, along with how it’s performing.

Review: What If? Serious scientific answers to absurd hypothetical questions

What if? From the creator of xkcd

It’s been a while since I read a physical book.  Most of my reading these days is done on the kindle and, while I still have physical text books for my maths degree, I have a lot of books just waiting to be read.  What If? by xkcd creator Randall Munroe is one of these.  I was given this as a present a few years ago and, despite my initial excitement (having been a reader of xkcd since about comic 17212) the book had sat on my bedside table under the kindle but just above the half-read “Sagas of the Icelanders” that I’d bought on my honeymoon.  Last week I picked it up and started reading.  I read just under half in that first sitting and then two days later finished it.  I wish I’d read it the day it was given to me.
