Bits and Bytes

Professional obligations have delayed some technical pieces but for now just wanted to pound out a few quick thoughts while the coffee brews in the French press (oooh la la la).

On Tablets

Five years ago I made my first Apple purchase ever, adding a 3rd generation iPad to the household.

It has been a remarkable value. The pad has served the family well over many thousands of hours of service, over a thousand full charges, and still last for hours. The screen still looks great (something that wouldn’t necessarily be true were it OLED-based — I love OLED but it is does have downsides for long-term heavy usage). From a cost-versus-usage perspective it is quite possibly the most effective purchase I’ve ever made, the Nexus 7 2013 just slightly behind.

The device is no longer supported in recent iOS updates, and is showing its age on the speed front.

It was finally replaced, or at least augmented with a new model.

The iPad is without peers, and what once was a competitive space has been winnowed out to junk extremely low-end Android devices, the iPad in the value space (that original 3rd gen was $620CAD. The 7th gen replacement is $399CAD), and then Samsung devices up with top-tier iPads and Surfaces in the high end.

If there’s a question about what tablet to buy, the answer is iPad 9 times out of 10. And even with our smartphones getting larger, having a pad to fall back to when convenient not only gives you a more generous, readable screen, it makes battery management so much better. Not just retaining a charge, but avoiding lifetime battery exhaustion of the sort that has been making the news.

A pad remains a great compliment to a smartphone and a desktop.

Since that original Apple purchase this household has added a lot of Apple to the mix, in every product line. My workstation is a Ubuntu/Windows box aside a Mac mini (a product that needs a refresh, though moving to an external USB3 SSD is elegantly simple). My main smartphone a GS8, but my fallback / dev device is an iPhone 8. There are great options in all spheres.

The Nexus 7 2013 is still running well (it is extraordinarily unfortunate that Google abandoned the line, jealous of all the lucre Apple was pulling in, failing to emulate it with the miserable, grossly overpriced Pixel lines), but while both devices are aged and out of the OS support window, the Nexus 7 has me much more hesitant to trust it among my children, which was validated when I put it away one night to find an R rated ad layered over the screen, using draw on top permissions (despite not having the permission, instead using an unpatched exploit), kicked off by a Minecraft-clone my son had installed. In a rational world this developer would be punted from the platform for eternity, but in the Google world they just need to pay $25 and be up on the platform again minutes later with another fake identity.

If Google Play goes without curation — which is a choice that has many merits to go with the downsides — at least offer the optional validation of the developers/publishers (whether individual or corporation) and allow users to limit installs to those that are verified. Make the threat of being kicked from the platform something that actually scares those who install shady advertising library from exploitative, garbage companies.

The Dirty Blockchain

Got forwarded this submission to Hacker News, seeking my opinion given my recent comments on blockchain related technologies (where I have become involved in some extremely high performance/low latency initiatives).

I try to avoid negative commentary, and negativity in general, but that submission struck me as curious. Enumerating every grievance of an entire industry and then assigning it to a single implementation/opportunity is not a productive approach.

The overarching blockchain concept, which applies to merkle trees, shared and cross signed ledgers, data transparency, etc, and does not necessitate proof-of-work, entails an enormous number of technologies, uses and implementations. It isn’t a magic cure-all (or even cure-many, and might actually inflict and infect many, being misused and abused), it is over-hyped, but it isn’t productive to discredit anything tangentially related. Buying into the anti-hype can be as misleading as buying the hype.

For years people have linked to some old pieces here for anti-NoSQL firepower. I never wanted to champion that cause (the cause of being anti-something, or of being defined by negativity). As with the blockchain, often people were trying to counter the hype, but in doing so perilously veered to an anti-position that was sometimes just as coarse.

It’s a very nuanced industry.

I Was Wrong on Intel

A few years ago I exclaimed that we shouldn’t count Intel out of mobile. I like to revisit those old statements and own my mistakes, and in that case I was completely wrong. [I also thought HD-DVD would beat BR, but in reality streaming beat both].

At the time I had viewed Intel as a remarkably capable company that was most afraid of competing with themselves, but that would stay at the edge of relevant in the space. The compete-with-themselves bit remains true, but they are completely irrelevant in mobile now.

In the void mobile chipmakers have made enormous advances at eventually competing with Intel’s cash cow.

The notion of Apple moving all of their devices to variants of their ARM processors is a very real possibility now: There remains a performance differential, but scale the chip up to the power profile of a desktop or a laptop, copy/pasting cores as necessary, and enormous performance is possible. The single core performance is already there, which is simply extraordinary given the traditional strengths of each variant, and the classic design philosophies guiding each architecture.

Intel’s missteps lately have been surprising, and they seem to be stumbling at everything they do lately. It has been a lost half decade, and they don’t seem to be recovering.

Kotlin and Swift

One of the reasons I picked up Kotlin on the Android (and general Java) side was that as a language it shares a lot of parallels with Swift, which I’d been embracing at the same time.

After several projects and many tens of thousands of lines of codes, just wanted to reaffirm that Kotlin is fantastic. It carries some warts from its JVM targeting foundation, but if you’re doing Android and you haven’t embraced Kotlin, you’re missing out.

On Editing Old Posts

I periodically edit existing posts to make them more concise and efficient for readers. Often this entails removing adverbs — it is remarkable how seldom the word very adds to a statement — and parentheticals. I have a bad habit of trying to cover possible counterpoints when I make a statement, yielding unnecessary wordy entries.

It’s worth making the time a little more beneficial for readers. One of the reasons I didn’t make use of podcasts early on was that most were often improvised with a lot of umms, casual banter, etc, offering little real content density to listeners outside of entertainment (which is now the case with many YouTube channels). Lately I’ve found a lot of fantastic podcasts that clearly have considerable preparation and research to provide a high value/high content audio experience  to awareness/education.

Things That I’ve Enjoyed Lately

Admission Requirements – wonderful book of poetry by Phoebe Wang

PlayerUnknown’s Battlegrounds – current diversionary game to quickly hop into for a short round, with a high-intensity conflic. Most rounds are 98% collecting things, 2% getting shot at from sources unknown. Lots of bugs, lots of hackers (especially in third-person perspective — stick to FPP), but the exhilarating game experience makes it worth a try

Cohen Live – an album that I return to every couple of years, wondering how I ever put it aside

The Problems of Philosophy – Enjoyable read by Bertrand Russell. The whole field of philosophy has fascinated me lately, and I also got great value out of the Kindle edition of The Philosophy Book (Big Ideas Simply Explained)

Virtually any Nordic / Euro show added to Netflix – Have loved so many of these.
