bitcoin additional thoughts and a great comic

cartoon non sequitur for 2018 Jan 18- on bitcoins loss of value

Extending from an earlier post on bitcoin thoughts … Finding an exchange is tricksy as they could dissapear overnight, so many cryptocurrencies are dropping value, yet companies and governments are weighing in on the issues surroudning CCs – like implementing taxation guidelines for virtual goods.

Aside – folks I played online games with laughed at  concept of paying real money for in-game gold in WoW many years ago, despite wow, eve and many other games demonstrating that gamers have an appetite to do so. BTC is certainly different enough to not be a fantasic comparison (not decentralised, owned by one company, artificial levers on supply and demand), however WoW gold has a much better stability than bitcoin. Thank about that for a sec!

Personally speaking I think the recent adjustment downward by 30%+ on most of the leading CCs is very reasonable, and a lot more is probably on the way. This is because there is very little difference in the features and benefits of almost all cryptocurrencies, and while the different offering have useful features to offer many “investors” who helped the bubbles proliferate probably do not appreciate the details enough to differentiate. Frankly though a few countries have said they will inhibit CC growth (like China), or seriously hunt for taxation revenue from profits (Aus and USA that I know for sure), so the free and open nature of all virtual currencies is evaporating. And there is nothing stopping another CC from starting up and taking the “popular name” market share from BitCoin. e.g. A CC backed or unofficially sanctioned by China’s government would be very powerful. Maybe China is watching and learning about CCs so they can capitalise. Perhaps Google, Amazon, Alibaba, or Yandex will back or create one too which would make for a powerful market offering too. Now that bitcoin has having a huge adjustment it might be time for another virtual currency to rise, and use the brand of a big corporate as staging to market penetration.

Looking the price adjustments another way: investors who hunt for get rich quick have now seen BTC hurt them. Other CCs are following downward. What is the intended use for virtual currency? I’d like to know why people are still buying CCs in bulk. The inventor of DogeCoin used them to donate money to charities, and Bitcoin can be used as currency for a few major companies and strange-ish products; note that these companies take regular money too – so buying a bitcoin just to buy a product isn’t always logical.

Products need customers who have problems to solve, and CCs don’t see to have enough customers (except for the speculators). Digital currencies are getting a lot of attention now due to their rise and fall, so if they stabalise it will be good to watch where the investing market goes next. No idea where the prices are going but this is so interesting to watch (my bet is downward, hard to about $450 for BTC, because at that price they might actually be useful to humans as well as investors).


Does Meltdown or Spectre affect normal users? Probably not

The impacts of two new CPU security expoits are being tested at present, and I’ve seen two different views – one that it will have an impact (of single digits), and another saying that those single digits are not relevant (or almost not) for gamers and normal users because they don’t involve the kernal.

TLDR = You have no choice except to Patch and move on. Maybe keep reading in the background.

  • The CPU exploit probably won’t greatly impact a gamer or a normal user, and if they do – it will be a small slow down.
  • Pretty much everyone is nominally affected, so the playing field is still level.
  • Patching the machines is important (duh!).
  • There are no known exploits in the wild yet.
  • It will be years before consumer grade hardwar is released which won’t be impacted, because deisgning new CPUs takes time, and then the companies will need to get the hardware into market.

The background:

a Bitcoin random thought – its now a darn risky investment artefact

Quickly to be frank – A family member with a traditional banking and investment background asked me about bitcoin as an investment option – I had to tell him that I’m no expert, and he should play with CCs with as much many as he’d like to throw away. In fact I then suggested that giving money to strangers might be just as valid an investment. It is a fabricated artefact – here is why.

Bitcoin started as a techie concept which took a few years to be taken seriously by the techies, then moved to a very enticing and interesting practical implementation with benefits (pizza, games, anon purchases), and is now a mechanical artefact that suits investors and risk takers. This write-up by Seeking Alpha is an example – which indicates that Bitcoin is at its (apparently) weakest stage. Likewise the other CCs are not at all mature. Its a growth stage that may lead to a great long term currency when one of the many CC options becomes stable and ubiquitious. BitCoin is neither at present, but is very dynamic and interesting if you can throw away the time and money it costs you to investigate.

What that means is nobody is buying pizza anymore, investors are solidly looking at it for quick bouncing returns. That’s not a good time to buy, especially when a coin costs UD$14,000 (+/- 15-35%) + high fees. At this stage in its life I don’t think it is much different from the stock market, except there is no centralisation or control, nobody to hold accountable, frequent technical issues, and no demonstrated longevity. Think about that risk profile – its amazingly risky by comparison and people are buying and selling in large amounts recently.

I’m intersted in what happens later – when more curencies are in the market, offering different options for stability, style of implementations, or by financial institutions or countries. We are amid the maturing of CCs, and there are great times ahead. If I more time and $5k I was happy to throw away I’d still buy-in, and I’d take a serious look to other CCs instead of BitCoin, or wait till BC stabilises a lot more. The enticement is to find another CC which costs $50/coin, and hope it tripples as that would be enough of a test.

Firefox Mr Robot add-on fail is akin to U2 fail

I’m staggered to read that Mozilla tried to advertise the TV show Mr Robot by forcing the install of an add-on. Yes, it was disabled by default, but thats is plainly a crap thing to do. So much for thinking of the community or for acting responsibily.

As reported by Shaun Nichols of “The Register” – Mozilla automatically installed a weird add-on to Firefox on people’s computers – an add-on that turned out to be a marketing promotion for the hit telly show Mr Robot.

The reactions are justified and blunt. Its almost implausible, but happened.


I do not understand how this would have been seen as clever advertising, and was probably damaging to their geek-cred. As if anything the geek audience of Mr Robot tends to be more security and IT sector aware and wouldn’t like the move.

Did the music industry folks love it when U2 brute forced their new album into the iTunes media library? Broadly speaking no; there was a lot of bad press, and apologies.

Mozilla chief marketing officer Jascha Kaykas-Wolff has posted a mea-culpa on the Mozilla blog. “We’re sorry for the confusion and for letting down members of our community,” Kaykas-Wolff wrote.

“While there was no intention or mechanism to collect or share your data or private information and The Looking Glass was an opt-in and user activated promotion, we should have given users the choice to install this add-on.”

The exec also said Mozilla did not sell out its loyalists to a TV network – this was done for free.

“Over the course of the year Firefox has enjoyed a growing relationship with the Mr Robot television show and, as part of this relationship, we developed an unpaid collaboration to engage our users and viewers of the show in a new way,” Kaykas-Wolff explained.

Somehow, that just makes it even worse.

I don’t care that they didn’t get paid, I care that they did it. If fact the did sell out, however their price was exceptionally cheap in dollars, and expensive in reputation damage.

So bye-bye Firefox! You’re done for another few years (or until Chrome does something equally stupid and I’m forced to pick between the lesser of two evils).

xkcd on self driving cars – bravo!

self_driving_car_milestonesGreat comic as usual. Its only as the concepts drift wistfully past your personal point of insanity that it makes you think something here might be unreasonable. Should the AI decide that mimicing driver behaviour is better than efficiency; then we are all doomed.

  • Cars that indicate left and never turn,
  • Cars parked in no standing areas,
  • Cars honking at pedestrians,
  • Pedestrians carrying devices which send out signals identical to automated cars, so they get equal treatment.
  • Roombas striving for equal rights.

I hope our (soon to arrive) AI overlords have a dark sense of humour, and better judgement than the Road Traffic Authority.

New Firefox and Handy Chrome Extensions, bloat & Security.

Even after reading that my old favouraite browser Firefox is making a comeback, I think it will be a while before I try to abandon Chrome; and the reason is the integrations and extensions are great for security and quality of life. I also think it is best to keep the number of extensions limited, because that in-turn might keep memory bloat down and should limit unknown future vulnerabilities.

  • Fair AdBlocker – a browser ad blocking widget, which is mandatory to me; especially as there are websites where I am very happy to see their ads and you can choose what to see.
  • uMatrix – javascript controller, which lets me block/allow scripts specifically by page and domain. Javascript is a nightmare for good security as it is so easy to exploit, and I’m hoping this widget will make that less likely.
  • a few GoogleDoc related plugins, but not all of them, as each adds bloat. I do love GoogleDocs, sure they lack a few features, but they are pretty amazing.
  • a password manager, I’m not goiung to say which (because while everyone should be using one, I don’t think I should give a hacker an easy start), but its one of the big ones and is excellent in terms of features and ease of use UI.
  • HTTPS Everywhere – which tries to force your browser session to always use the https protocol; in plain terms that means your should be a little safer.

Thats it.

Understand too that enabling widgets and extensions also introduces risks too. Who created it, are they seeing your traffic in real time (like many of the spell-checkers)? What information of yours do they store externally? What if they are hacked? Recommend being smart and using as few as possible.

Back on browser choice – Chrome is plenty fast as is, has a linked ID to my home PC and phone so my bookmarks will sync between devices, and does not crash. The ad blocking and password manager are tools I cannot live without. And although I’ve ony be using uMatrix for a very short time it has already impressed.

One key feature I read about recently was having FireFox tell you if the site you are visiting is also listed on HaveIbeenPwned (via Lifehacker) – such a great widget idea, and one that has been written as a plug-in for Chrome and others for a long while.

I really recommend registering for HIBP too; in fact I registered my families accounts for them.

Happy & safe browsing folks.

Blockchain and Bitcoin Humble Bundle

The current Humble Bunddle is all about Bitcoin and Blockchain – two topics which are well understood in technical circles, but not well understood in many others. Like the post on Crypto and Cybersecurity with the Humble Bundle, I think this is worth seriously considering. At the $8 level it is good value and handy to have a handful of electronic textbooks. I’m no expert, but I plan to at least validate what I think I know against useful sources. Happy reading.

iPhone IOS 11 broke the podcast app

I’m angry enough to rant about how broken the Podcast app is now after the IOS 11 upgrade; it’s overflowed into this blog. Normally I’d try to hold my angst in check however Apple needs to see the feedback from multiple places.

Essentially the update to IOS 11 for the Podcast App has totally reworked the UI and very importantly removed the Unplayed list, the Mark as Played features, which makes it difficult to use. The UI changes are illogical and clunky – It’s horrid. 

I decided to post feedback direct to Apple via their feedback section and speak with my device – so I’ve converted to using Overcast. It’s free, logical, and has well thought out features. It’s good enough that I might subscribe to the paid version.

4GX Wifi Plus- How to reset the device

I’m using a Telstra 4GX wifi Plus hotspot widget when I ‘m the road at present, and the silly thing locked up while charging. It displayed the 4-5 power bars and little else on the lcd screen.

I started playing with it as I couldn’t find instructions online – it’s like an expensive figget-spinner. To reset the 4gx: Hold the Power and WPS buttons in for 10+ seconds and the device will shutdown. Then start-up and it *should* be back to normal.

Humble Bundle on Cybersecurity and Crypto

Heads-up on a great Humble Bundle on crypto, security, hacking, and all sorts of related topics. As a pay-what-you-like deal it’s amazing given these books are worth. I’m really keen to read Threat Modeling: Designing for Security and Cryptography Engineering: Design Principles and Practical Applications; that is my bed side reading set for months to come. Offer ends around the end of July, and found via Bruce Schneier’s blog.
