Amazon SES now offers inbox placement metrics and blocklist monitoring

29 May 2026 @ 9:48 pm

Today, Amazon Simple Email Service (SES) launched a new set of deliverability features that help customers get more information about their outbound sending deliverability performance and reputation. Customers can now see the percentage of messages that are placed in recipient spam folders based on samples of industry data, as well as see when their domains and IPs are listed on public email sender block lists. This makes it easier for customers to optimize their sending content to maximize customer engagement.  Previously, customers could use SES' Virtual Deliverability Manager to visualize the full end-to-end journey of email deliverability metrics. This included delivery rates, bounce rates of various types, as well as complaint, open and click rates. Customers did not have visibility into how many emails were placed in the spam folder, making it difficult to estimate how many emails were actually seen by recipients. Now, based on representative data sampled fr

29 May 2026 @ 4:01 pm

Cisco (Nasdaq:CSCO) is the dominant vendor in enterprise networking, and under CEO Chuck Robbins, it continues to shake things up. Cisco’s momentum is accelerating across multiple fronts, driven by demand for AI infrastructure, campus modernization, and strategic silicon investments. Here’s the latest Cisco news, research and analysis.

Meta considers becoming a hyperscaler

29 May 2026 @ 3:58 pm

Meta has raised the possibility that it could be joining the likes of Amazon, Microsoft and Google in offering cloud services at some point in the future — although potential customers shouldn’t be adding the company to their suppliers list just yet. When asked about plans for offering such services at the company’s annual shareholders meeting,  Meta CEO Mark Zuckerberg said there was a possibility of the company competing with the major hyperscalers. “It’s definitely on the table.” He explained that di

Zero trust isn’t broken, but most companies are doing it wrong

27 May 2026 @ 4:23 pm

Zero trust is 15 years old, and like many teenagers, it can feel misunderstood and underappreciated. The concept of zero trust was first defined by John Kindervag, a Forrester analyst at the time, as a strategy to replace the outmoded perimeter security model with a “never trust, always verify” approach. But going from principle to practice isn’t easy. Accenture reports that 88% of organizations have encountered significant challeng

As AI datacenter memory becomes hot commodity, SK Hynix makes it cooler

27 May 2026 @ 4:04 pm

South Korean semiconductor giant SK Hynix has announced a new type of high-bandwidth memory (HBM) for AI datacenters that improves heat dissipation by integrating a cooling layer within the memory package itself. The change could allow AI processors incorporating the new memory to run faster, or reduce cooling costs. Traditional chip cooling architectures are largely external; heat dissipation happens after it leaves the package. For the HBM memory used by AI, which vertically stacks memory chips on top of one another to improve latency and memory dens

Cisco research finds standard AI safety benchmarks miss the real threat

27 May 2026 @ 1:05 pm

Enterprises deploying closed AI models have generally relied on published safety benchmarks to assess risk before procurement and deployment decisions. New research from Cisco’s AI Threat Intelligence and Security Research team finds those benchmarks may systematically understate the threat. Standard safety tests submit a single adversarial prompt and record the model’s response. Multi-turn attacks work differently. An attacker maintains a conversation across multiple exchanges, iterating and adapting based on each response until the model yields. The report pair

Cisco redefines ‘job-ready’ for network engineers with its certification overhaul

IBM plans $2B quantum chip foundry; government will pay half

The US government has awarded IBM $1 billion to help establish the first purpose-built quantum chip fabrication unit in the US. The Trump administration’s investment is being matched by IBM itself and will result in the establishment of a new company called Anderon. The new business will build its factory in Albany, New York. IBM has pioneered quantum computing for decades. “Our work in silicon wafer fabrication has been a key to IBM’s success and will

Cisco: AI traffic is radically reshaping WANs

22 May 2026 @ 2:43 pm

AI agents generate up to 450% more network traffic than humans can, and they’re beginning to reshape network traffic patterns in measurable ways. Enterprise network traffic without agentic AI is expected to grow 2.5x in the next decade — agentic AI adoption will push that growth to 9x compared to current traffic levels, driven by autonomous task execution and inference-heavy workflows, according to new research from Cisco. Cisco’s new study, AI Impact on Wide Area Networks 2026, finds AI and agentic AI will not only increa

xAI-Anthropic deal signals the rise of AI compute as a standalone business

22 May 2026 @ 8:47 am

New SpaceX IPO filings suggest frontier AI firms are beginning to treat compute infrastructure as a standalone commercial business, with Elon Musk’s xAI agreeing to provide large-scale AI capacity to competitor Anthropic. The filing disclosed that Anthropic agreed to purchase compute services delivered through xAI’s Colossus and Colossus II AI infrastructure clusters through May 2029 under an agreement valued at roughly $1.25 billion per month. The arrangement is notable because Anthropic competes directly with xAI in the market for frontier AI models and enterprise AI services, suggesting at least some AI developers are increasingly willing to buy large-scale compute capa

Creating a dump file from a Task Manager process fails with the error "The system cannot find the path specified"

I have a Windows Server 2022 VM occasionally experiencing lockups due apparently to some software that has a CPU leak. The software vendor recommended collecting a system dump file of the process while it is experiencing this runaway CPU leakage as part of the troubleshooting process, but when I go to Task Manager and right-click the runaway process and select "Create dump file", I get an error message: Screenshot of dump process window stating "The system cannot find the path specified" The operation could not be completed. The system cannot find the path specified.

Apache2: Virtual hosts (htttp, https) and Directory directive

27 May 2026 @ 12:40 pm

We have a legacy server that needs updating. During this process I noticed some peculiar bevahior. Again this thing is ancient and internal only. It was http-only but some new part required https so I do have a certificate now and ssl setup. There are 2 virtual host: for port 443 and 80. Now the strange thing is one of the legacy websites using a Directory directive and only configured in the port 80 (http) virtual host works just fine on https even though it is not configured in that virtual host. How is this possible?

How to allow ssh login using sssd when user belongs to both groups?

27 May 2026 @ 6:19 am

We have FreeIPA server holding all the users and groups. And there are a lot of Debian clients to it (by using freeipa-client package). This sets up sssd service. We have multiple teams working on multiple products and a semi-automated way of giving production access on request. Previously there was a single team setup, and we had this in sssd.conf for production servers: simple_allow_groups = allow-production Users had to request being added to group, where they would be removed automatically when request expires. Now we want to add a separation by product, so that users not belonging to a particular product, would not interfere even if they had been issued production access. We tried this: simple_allow_groups = allow-production,product-a However, this allows login if user belongs to one or the other group. How can I make this an "and" condition, allowing l
