All Systems Red

This book was a short but fun read. Sufficiently short in fact that perhaps it was a little over priced, but not outrageously so. It follows an adventure of a slightly rogue but generally nice cyborg SecUnit which has charmingly named itself MurderBot. That's confusing, because said cyborg is too busy being depressed and anxious to actually do much murdering. I will definitely read the sequels.

The Man Who Broke Capitalism

With Cisco announcing that they no longer need 12% of their staff this calendar year (5% in February, and another 7% in September), I am left wondering what is so terribly wrong with American Capitalism. Interestingly at about the same time someone recommended I read this book, so here we are -- seeking to understand the behavior of our corporate masters once more. This book starts with this quote: To understand a civilization, consider its heroes. Which is telling because its so true. I think it also works for organizations -- if you want to see the values of an organization, don't look at what they say, look at who they promote and idolize. That's really the author's point though, so I shouldn't take too much credit. It's clear from the start that the author doesn't like Jack Welch or his leadership of General Electric and that he thinks Welch's legacy is toxic. Honestly though, he makes a pretty convincing argument that leaves me not being a huge fan either and certainly GE didn't survive the experience of Welch and those he chose to replace him upon retirement. It is asserted that Welch had three main maneuvers in business: downsizing;…

Digital Minimalism

  • Post author:
  • Post category:Book

This book argues that technology, especially social media, has been deliberately engineered by Silicon Valley to be addictive, and that often there are detrimental impacts to the products we all use every day. That argument makes sense in that these products are measured by the amount of time they are used per user (and thus the advertising revenue generated), and have evolutionary pressure to find ways to increase user minutes per day. There is also research cited in the book that anxiety levels in teenagers have increased in a manner which correlates with the release of the smart phone. Now, I don't think I could ever be a digital minimalist as described in the book, especially when work expects so much connectivity from me (it will be interesting if a right to switch off ever passes in Australia, put it that way), but I do think there are interesting ideas here. For example, asking why you have certain technology is probably reasonable. The low hanging fruit here seems to be smartphone apps for most people -- can you explain why you have all those apps installed? Especially when many of them are bad for your privacy? The bar proposed by…

Fifty Things That Made the Modern Economy

  • Post author:
  • Post category:Book

This book is an interesting read coming straight off the back of Human Origins. The book starts out by explaining the impact the invention of the plow had on humanity -- it asserts that farmers being able to produce substantially more than they needed for their own subsistence was a driving factor in the creation of both other specializations (by freeing people up from farming), but also a more unequal society (as it allowed a ruling class to live off resources produced by others). This is an interesting assertion to me. Next the book moves on to observing that with all innovations there is a winner and a loser. An early example is the phonograph -- before the invention of recorded media there was a market for quite-good-but-not-great performers to entertain people. Once there was an ability to record great performers, the earning capacity of the great performers went way up but the earning capacity of the not-quite-great performers went down. So while society overall might benefit from innovation, it is not true that all participants in the market benefit at the time of the innovation. The book then starts walking through a series of inventions. Each is presented as…

The Cuckoo’s Egg

  • Post category:Book

In 1986, Clifford Stoll and his coworkers were frustrated by what they thought was a billing error of 75 cents in their monthly accounting. Suspecting a software bug, the new guy (Clifford) was put on to working out the error as a starter problem while he got familiar with the systems he was to manage... I've been home sick this week with a chest infection, and what with having a limited oxygen supply I didn't feel like I was braining super well. So what better way to pass the time between naps than another old book I've read before? This is another book I must have read before I started blogging such things, but discussions of old computing systems made me a bit nostalgic for a good gold fashioned tale of computer hackery. The story has some historical significance too, as shown by this quote from Wikipedia: This was one of the first⁠ —⁠ if not the first ⁠— documented cases of a computer break-in, and Stoll seems to have been the first to keep a daily logbook of the hacker's activities. There are a few things which strike me about this story -- Stoll was lucky. He arguably committed…

I've owned this book since it was new in the year 2000, but it has sat on the shelf alone and unloved for at least 20 years. I think I did probably read it back then, but it pre-dates blogged notes about books like this one. However, with my new found interest in assembly language programming for ancient CPU architectures, this seems like the sort of book which I might enjoy again. That said, let's be honest here -- the content is interesting, and this book is still recommended as the best introduction to this topic, which is impressive after a 25 year lifespan -- but Shakespeare this ain't. So I found the book interesting and enjoyed reading it, but wont say much more than that here. I am left with an urge to understand UEFI more. Maybe I should write a bad boot loader? Either way, I've had to add some books on that to the Amazon wishlist now...

Adventures in exploding power supplies

So this went well... The Intel 4004 microprocessor has slightly weird power supply requirements by modern standards. You see, it needs to be supplied with +5V DC, and -10V DC at the same time to work. (It turns out that this is an artifact of the MCS-4 chipset using PMOS technology not the more modern CMOS. Wikipedia has a good description of the constraints of PMOS, but these include the requirement for a number of supply voltages including a relatively negative voltage.) Now, I found this example circuit in someone else's project: Which to me looked quite a lot like these kits from ebay being fed by an AC power supply: So I ordered a kit off ebay, and then ratted around in the garage to find a random AC power supply. Luckily I found one, because they're not super common compared to the DC power supplies I have huge mounds of. Now of course the kit had no assembly instructions apart from the markings on the PCB, which seemed mostly good enough when coupled with some random googling for polarity information. However, I really needed documentation about the input pins. However, that kit appears to be this aliexpress listing, which…

New Scientist Instant Expert: Human Origins

  • Post author:
  • Post category:Book

This book triggered my weak spot. There I was wandering in a book store and it caught my eye. The combination of the promise of instant expertise and and interesting topic area was too much for my already notably poor impulse control with books and a purchase was made. Covering from our distant origins from probably Asia, to stone tool use on African grasslands, to the invention of cooking and farming. The book asserts that 20% of our basal calorie burn is our brain, which drove the adoption to eating meat. While I'm not disputing the number, 20% seems like a lot to me. I wonder if that explains why I find training courses so tiring, my brain is literally consuming extra energy? As an aside, a study by Richard Wrangham mentioned in this book asserts that to live a leisurely western lifestyle using only raw vegetarian food, you'd have to consume 9% of your bodyweight a day. That certainly meshes with the "eat a salad" weight loss advice! So in the end, do I think I am an expert on human evolution? No, not really. The book was an interesting read and I enjoyed it, but perhaps the title…

Colony One Mars

I bought this book because Amazon recommended it to me and it got good reviews. There's a lesson there somewhere. You see, I didn't realise when I bought it that the book is self published, and its a little bit... awkward. Its little things, like clearly needing an editorial pass to make the phrasing flow better, and the fact that the text on the spine of the book is upside down. Literally the first line of the book has a weird justification that looks like Microsoft Word at its worst. Now, I'm not opposed to self published books -- the Silo series (Wool, Shift, and Dust) are self published for example, as is Unix: A History and a Memoir and I liked all of those. That said, first impressions do matter I think. Overall I'd say the sort is interesting, if a bit shallow. The level of plotting is probably in line with what you'd expect from a talented teenager. For example there's not much foreshadowing, characters instead just outright state their nefarious intentions. In the end, I got 85 pages in and realised I just don't care, so I stopped. This book is definitely going in the charity pile.

Project Orion

I was quite excited when this book arrived. It's a bit old (early 2000s) and therefore a bit hard to find, so when Amazon randomly had a "new" copy I snapped it up. This copy is definitely unread, but yet still yellowed with time and the binding is a bit sad. Project Orion is the story of America's attempt to build interstellar space ships powered by small nuclear explosions in the early 1950s. The story is told through the lens of one of the children whose father was a principal researcher on the project and who has now interviewed a lot of the players as well as reading de-classified historical documents. It should be noted that much of the program is still classified -- for example the exact minimum amount of plutonium you need to make a big explosion. The 1950s seem to have been an interesting time for nuclear research, as the technology was seen as both generally hopeful in the sense of finding peaceful uses for this destructive capability, while also being terrifying with the prospect of mutually assured distruction. This project started before NASA existed -- at the time each major branch of the military was competing…
