Deck.blue brings a TweetDeck experience to Bluesky users

With over 3 million users and plans to open up more broadly in the months ahead, Bluesky is still establishing itself as an alternative to Twitter/X. However, that hasn’t stopped the developer community from embracing the project and building tools to meet the needs of those fleeing the now Elon Musk-owned social network, formerly known […] © 2024 TechCrunch.

5 tips for dealing with Day 2 Kubernetes operational challenges

Lukas Gentele Contributor

Lukas Gentele is the CEO of Loft Labs, which builds open source developer tooling for Kubernetes.

Kubernetes is a wonderful but complex software that can present significant “Day Two” challenges when put into production.

Developers who are new to Kubernetes — and most are — face a large knowledge gap when they look to sustain and optimize Kubernetes clusters.

In this piece, I will share several ways to address problems as they arise.

Optimize your Kubernetes cluster for cost

As adoption of Kubernetes rises, the need for applications and engineers to access clusters is also growing. However, it is neither feasible nor cost-efficient to always use entire physical clusters to achieve this goal.

Virtual clusters are a great way to reduce costs. In a scenario of 100 developers, we calculated up to 78% savings by using open source virtual clusters.

Leveraging virtual clusters with open source software such as VirtualCluster or vcluster lets Kubernetes operators can run multiple virtual clusters within a single physical cluster, thereby increasing the tenancy of each. By utilizing computing resources via this more communal method, organizations can save on computing costs as opposed to operating entirely separate Kubernetes clusters.

Increase tenant isolation

By leveraging policy engines, it’s possible to implement software security guardrails on your cloud-native Kubernetes infrastructure.

Another great benefit of virtual clusters is that they are isolated from other users on the cluster. This gives each user their own workspace that looks and feels exactly like a physical Kubernetes cluster.

In addition, virtual clusters enable a stricter form of multitenancy compared to namespace-based multitenancy. One of the main concerns with namespace-based multitenancy is that it cannot contain cluster-scoped resources. Many applications must create, or at least access, cluster-scoped resources like nodes, cluster roles, persistent volumes and storage classes.

Virtual clusters also provide security benefits by increasing the isolation in multitenancy clusters via:

  • Full control-plane isolation.
  • Domain Name System (DNS) isolation.
  • Resources created on a single namespace.

Organizations seeking a solution for multitenant applications that provide greater isolation for resources shared among their clusters should consider virtual clusters as an option. On top of saving costs and being simpler to deploy, they are also easier to manage than physical clusters.

Provide integrated development environments

Nimbus launches tiny EV prototype that’s like a motorbike with a roof

As shared e-scooter companies have infiltrated cities and e-bike sales have soared, micromobility has been offered up as a panacea to save us all from the ill humors and packed streets caused by gas-guzzling cars. However, one of the major roadblocks in front of well-intentioned city dwellers who’d love to trade in their cumbersome and environmentally unfriendly vehicles for an e-bike or scooter remains: What happens when it rains? Nimbus, a California-based electric vehicle startup, wants to solve that problem with a simple solution: Put a roof on it. The company recently came out of stealth with a prototype for its Nimbus One, a tiny, three-wheeled EV that “combines the convenience and cost of a motorbike with the safety and comfort of a car.” The Nimbus One. Image Credits: Nimbus The thin, pod-like vehicle is only about 2.75 feet wide and 7.5 feet long, which Nimbus says makes it three to five times smaller than a compact car — the better to park and navigate busy urban stree...

Ivella is the latest fintech focused on couples banking, with a twist

Money can make people moody. There are layers of privilege, or lack thereof, that can make even the simplest conversation about bills feel like baggage to deal with. Translate that discomfort to relationships and it can feel like an awkward — and fragmented — dance on who pays which bill when (and how). Ivella , a Santa Monica-based startup, wants to build banking products for couples to take away some of these tensions. Led by CEO and co-founder Kahlil Lalji , the startup is launching with a split account product that just raised $3.5 million in funding from Anthemis, Financial Venture Studio and Soma Capital. Other investors include Y Combinator, DoNotPay CEO Joshua Browder and Gumroad CEO Sahil Lavingia. Lalji, who helped creators with digital content before jumping into the world of fintech, says that the startup was born out of his own frustration at the expectation that couples would just use Venmo unless they were married. The best solution, so far, has been joint accounts...

Coinbase Q2 earnings exceed estimates, signaling potential market recovery

Coinbase reported its second quarter earnings Thursday afternoon after the bell, beating market estimates. During Q2, the second largest crypto exchange by trading volume generated total revenues of $707.9 million, down from $772.5 in the previous quarter and $808.3 million in the year-ago quarter. It also had a $97 million net loss and generated a positive adjusted EBITDA of $194 million during the quarter. It was a mixed bag of estimates from analysts prior to the earnings report. Some expected lower results, while others were optimistic . But now crypto bulls and company shareholders alike can breathe a sigh of relief. “One year ago in Q2 2022, we started reducing our expense base to operate more efficiently. One year later, we’re proud to say that our quarterly recurring operating expenses have dropped nearly 50% Y/Y,” the company said in its Q2 2023 shareholder letter . In after-hours trading, shares of Coinbase rose 7% to about $96.70 after its earnings were posted, but re...
