New details released on Huawei’s intent-based network

On By Paul HubbardIn Computer scienceLeave a comment

Intent-Driven Network software. CampusInsight 2.0 is an upgrade to Huawei’s network insight engine and should be considered the intelligence that powers the intent. Network and application data is collected and turned into telemetry information in real time. Machine learning is then applied to monitor the network and predict problems. The network insight engine uses a digital twin of the network, so analysis can be applied and changes tested without affecting the production network. A digital twin is a virtual copy of the original item and allows companies to conduct real-time simulations

Fascinating. I usually see ‘intent’ used to describe ‘extracting meaning from customer input’, so this is a new usage. I’m used to deterministic networking protocols like BGP, so the idea of ML analytics and prediction makes me both interested and wary.

Make that ‘very interested and very wary.’ The prediction system seems like a way to address the worries though.

How to be a star | Dan Dreams of Coding

This is a bad place to be. You’re working hard. You’re creatively finding solutions to company problems. The developer next to you gets kudos just for doing their job, while your hard work and great ideas get ignored, and you get branded as being unreliable. The reason is simple – no matter how valuable you believe your side projects to be, your manager, business partners, and coworkers are depending on you for something else. If you aren’t delivering your assigned tasks on time and with a high level of quality, then anything else you’re working on is going to be ignored at best, seen as self-indulgent at worst.

It’s hard to find good career advice for software developers. This piece, which I’ve read half a dozen times, really is excellent start to finish. I’ve forwarded it around at work, bookmarked it and plan to share it when mentoring. Highly recommended.

Chevy runs Lucky Goldstar

Poking around the Bolt menus and it’s crediting LG for code:

I had wondered how Chevy software had improved and perhaps that’s the answer; interesting.

Still happy with the car. Charging it twice a week works well and lets us run around all weekend.

The extra range is hugely important and means we can use the car without worry as opposed to just a commuter.

The US Air Force’s largest plane transported a billion dollar satellite — Quartz

Most importantly, and expensively, it can survive a nuclear strike. Atomic explosions release bursts of electrical energy that can fry computers, even in orbit. This satellite is hardened to pass through such energy blasts unscathed. More than that, if the satellite loses touch with its control system on the ground, it can operate autonomously, continuing to provide service to its users. It’s the kind of communications network that sends a message of deterrence just by existing, since it would (presumably) survive a nuclear first strike. Au, proud of his work, scoffed a bit at the attention received by autonomous drone and car companies. His vehicle is operating at the real technological frontier.

A superb long-form piece from Quartz, perhaps the most impressive I’ve read from them. Worth your time.

Peeking Behind the Curtains of Serverless Platforms

As baselines, the median warmstart latency in AWS, Google, and Azure were about 25, 79 and 320 ms (respectively) across all invocations.

If, like me, you are using AWS Lambda or its competitors, this paper by Liang Wang et al is worth a careful read. Lots of well-done measurements of performance, isolation, instance lifetimes and more.

Functions as a service behave differently than the servers we’re used to, so be sure and understand your platform and how it behaves!

My first takedown request

On By Paul HubbardIn Site news, Watches1 Comment

So I got an interesting email today, a polite request to remove some content that is under embargo for a while. I’ve done so.

I’ll tag this post as 451, for obvious reasons, but this instance was a reasonable request that I’m only mildly sad to fulfill. I’m not trying to be an investigative reporter here, in this case I was doing a bit of searching and posting about what I had found.

I’ll update when the embargo is lifted or there’s related news.

Update 8/31/18: It was the unreleased Grand Seiko 9F GMT – now released.
