1. Maybe spend time looking at how new tech CAN help you rather than CAN’T help you – WoodITWork
Julian Wood compares how a presentation he gave on serverless was received differently by business people compared to IT pros where he works. In short, the business folks saw ways to get value out of the approach, while an IT pro looked for ways it wasn’t suitable for key workloads, but ignored other possibilities. As Julian notes “…sometimes we are a little myopic and only see what a technology CAN’T do rather than looking at the bigger picture. This can distance you from the business.”
2. NVMe over Fabrics for Absolute Beginners – J Metz
This is a great post to get you up to speed on the use of NVMe in a storage fabric (as well as a quick refresher on NVMe itself if you need it). Besides clear and sharp explanation, you also get useful diagrams and a few amusing memes.
J. Metz writes “NVMe over Fabrics is a way of extending NVMe outside of a computer/server. It is more than simply slapping the commands onto a network, and it still helps to know the pros and cons of each transport fabric as it applies to what you need to do. Remember, there is no such thing as a panacea for storage.”
3. The Soon To Be Famous Cocktail Napkin Wi-Fi Big Picture – WiredNot
When users have to wait a few seconds for something, they immediately blame Wi-Fi. Lee Badman isn’t having it, and he’s drawn up an illustration to tell you why.
“What you’re looking at is the proceeds of a discussion I recently had, where I pontificated about how most “wireless” problems really aren’t wireless problems, even though ALL network problems “feel” wireless to the average user.”
4. IPv6 Renumbering: A Pain in the … – Blog Webernetz
Johannes Weber had to switch his lab entirely over to IPv6. He was already running a lot of IPv6 and everything else was dual-stacked, so he didn’t anticipate a lot of trouble going full v6.
He writes “Changing the public IPv4 addresses was done in a few minutes, while it took me a couple of weeks until all services were running with the new IPv6 addresses likewise. It was not only changing interface IPv6 addresses, but lots of configuration details in almost all services/appliances where IPv6 GUAs were used as well.” This post walks through the gory details.
5. AWS ABC’s – Logging Into a New EC2 Instance – Packet Mischief
Joel Knight writes “Ok, you’ve just launched an Amazon EC2 instance (ie, a virtual machine) and you’re ready to login and get to work. Just once teeeensy problem though… you have no idea how to actually connect to the instance!
This post will walk through how to log into brand new Linux/BSD and Windows instances (the steps are slightly different for different OS families).”
1. Decentralisation: the next big step for the world wide web – The Guardian
As more power over the Internet accrues to governments and a handful of large corporations, a movement has emerged called DWeb that seeks to work around centralized government and corporate check points to avoid surveillance, censorship, and the monetization of Web browsing.
Zoe Corbyn at the Guardian writes “The DWeb is about re-decentralising things – so we aren’t reliant on these intermediaries to connect us. Instead users keep control of their data and connect and interact and exchange messages directly with others in their network.”
2. Can Mark Zuckerberg Fix Facebook Before It Breaks Democracy? – The New Yorker
I’m not sure he really wants to.
3. It’s the end of crypto as we know it and I feel fine – TechCrunch
This article by John Biggs compares the current gyrations in cryptocurrency values to the dotcom boom and bust of the aughts. It’s an apt comparison: lots of people are in this for short term gains, the ignorant and the bold have joined hands to swim out into uncharted waters, and valuations are skewed by heady visions of instant wealth. But rather than read a funeral oration for cryptocurrency, Biggs regards the current downturn as part of a maturation cycle, in which a few steely-eyed visionaries with long term plans will emerge and dominate.
4. Two studies show the data center is thriving instead of dying – Network World
Andy Patrizio at Network World looks at industry research touting the viability of the on-premises data center, writing: “Once again research is showing that rumors of the demise of the data center are greatly exaggerated: One study shows across-the-board growth in IT spending, while a second predicts that the financial services sector is really set to explode.”
