2018 Tech IPOs: Is Enterprise a Game-Changer?

Jon Swartz’s recent piece in Barrons asks “Is This the Year Tech IPOs Stage a Comeback?” Prior year IPOs did not meet expectations, with consumer companies like Snap and Blue Apron the poster children for a miserable performance.

But the speculation among the smart money is that 2018 tech IPOs will surge, and they’ll be driven by enterprise companies.

So, is enterprise the game changer for tech IPOs in 2018?

The Security Frustrations of Apple’s “Personal” Personal Computer: Device Access, Two Factor ID, and 386BSD Role-Based Security

Recently, a FaceBook friend lamented that he could not access his icloud mail from a device bound to his wife’s icloud access. He also expressed frustration with the security mechanism Apple uses to control access to devices – in particular, two-factor authentication. His annoyance was honest and palpable, but the path to redemption unclear.

Tech people are often blind to the blockers that non-technical people face because we’re used to getting around the problem. Some of these blockers are poorly architected solutions. Others are poorly communicated solutions. All in all, the security frustrations of Apple’s “personal” personal computer are compelling, real and significant. And do merit discussion.

Apple Store “Bait and Switch” IPhone Battery Gambit: Apple Giveth and Taketh Away

Beware the Apple Store “bait and switch” iPhone battery gambit. We faced this yesterday in Los Gatos, CA where they tried to claim a working iPhone 6s with a good screen / original owner was not eligible for their $29 battery replacement at the appointment because it had a slight bow in the frame.

Now, by this point everyone likely has some flaw in their old iPhone, whether it is a slightly dinged frame from being dropped to a minute crack or scratch under the frame. It’s normal wear and tear. And they likely didn’t have a problem replacing the battery before the discount was announced and replacements were more costly and infrequent. But now, it’s an issue.

They did offer to sell an iPhone 6s for close to $300! This is a terrible price. Don’t go for it. This is what they mean by bait and switch.

Intel’s X86 Decades-Old Referential Integrity Processor Flaw Fix will be “like kicking a dead whale down the beach”

Brian, Brian, Brian. Really, do you have to lie to cover your ass? Variations on this “exploit” have been known since Intel derived the X86 architecture from Honeywell and didn’t bother to do the elaborate MMU fix that Multics used to elide it.

We are talking decades, sir. Decades. And it was covered by Intel patents as a feature. We all knew about it. Intel was proud of it.

Heck, we even saw this flaw manifest in 386BSD testing, so we wrote our own virtual-to-physical memory mapping mechanism in software and wrote about it in Dr. Dobbs Journal in 1991.

You could have dealt with this a long time ago. But it was a hard problem, and you probably thought “Why bother? Nobody’s gonna care about referential integrity“. And it didn’t matter – until now.
