Amazon Athena simplifies federated queries with managed connectors

23 April 2026 @ 9:15 pm

Amazon Athena now offers managed connectors for 12 data sources, including Amazon DynamoDB, PostgreSQL, MySQL, and Snowflake. Managed connectors are AWS Glue Data Catalog federated connectors that Athena creates and manages on your behalf, so you can query data outside Amazon S3 without deploying or maintaining connector resources in your AWS account. With Athena, you can interactively query relational, non-relational, object, and custom data sources without moving or duplicating data. To get started with managed connectors, you create a connection for your data source in Athena. Athena automatically sets up and manages connector resources on your behalf, registering the data source as a federated catalog in AWS Glue Data Catalog. You can then query the data source alongside your Amazon S3 data and optionally set up fine-grained access controls through AWS Lake Formation. Federated queries with managed connectors are avai

Amazon Quick now supports multiple owners for admin-managed SharePoint and Google Drive knowledge bases

23 April 2026 @ 3:59 pm

Amazon Quick now enables you to add co-owners to knowledge bases and data source connections for admin-managed Microsoft SharePoint Online and Google Drive integrations. This makes it easier to collaborate across teams and reuse existing connections without re-entering credentials. Knowledge base owners can share their knowledge bases with two roles: Owner (full management access including editing, syncing, sharing, and deleting) and Viewer (query-only access). Co-owner sharing with the Owner role is available exclusively for admin-managed SharePoint and Google Drive knowledge bases. All other knowledge base types support Viewer sharing only. To share, navigate to the actions menu next to any knowledge base or use the Permissions tab. Administrators can also share data source connections, allowing other users to create knowledge bases from the same connection. Data source sharing supports Owner (create knowledge bases and edit connection details) and Viewer (create

Amazon Redshift supports UPDATE, DELETE, MERGE for Apache Iceberg tables

23 April 2026 @ 3:00 pm

Amazon Redshift now supports row-level UPDATE, DELETE, and MERGE operations on Apache Iceberg tables. Customers who use Iceberg to build interoperable data lakes can now perform data manipulation language (DML) operations directly from Amazon Redshift, without moving data to external processing engines. Previously, modifying individual rows in Iceberg tables required using separate engines, adding complexity and latency to data pipelines. With this launch, you can run UPDATE, DELETE, and MERGE (UPSERT) statements on both partitioned and unpartitioned Iceberg tables, including S3 Tables. Supported Iceberg partition transforms include identity, bucket, truncate, year, month, day, and hour. MERGE enables you to combine insert and update logic in a single statement for common data integration patterns such as change data capture and slowly changing dimensions. Tables modified by Redshift are compatible with other Iceberg-compatible

How AI is reshaping copper, fiber networking

22 April 2026 @ 8:15 pm

Data movement over the network is more important than ever, thanks to artificial intelligence and, in particular, dedicated AI data centers. Large language model (LLM) training and AI inference require terabytes of data stored in data centers the size of football stadiums. In addition, efforts to cluster multiple sites are increasing, which means that data-center networking distances are increasing. There are two forms of network cabling: copper and fiber optics. The two technologies are very different, but they coexist in data centers. Businesses need both to operate data centers at maximum efficiency. At the recent

SUSE is targeting enterprises weighing their VMware options with a new partnership that promises zero-downtime, automated migrations at scale. The open-source infrastructure company has announced a partnership with Cloudbase Solutions to integrate the Coriolis migration tool into its SUSE Virtualization stack. The aim is to remove the manual effort that has kept many enterprises on VMware despite Broadcom’s licensing changes. “In the post-VMware world, we see ourselves as a modern infrastructure layer for virtualization,” said Peter Smails, GM of Cloud Native at SUSE,

How Zero Networks is closing the network enforcement gap for AI agents

21 April 2026 @ 8:54 pm

The promise of microsegmentation has always been about reducing the attack surface in a bid to lower risk. In the modern era of AI agents, existing methods of network segmentation might not be enough anymore, according to Zero Networks. The company, which was founded in 2019, built its platform around the argument that existing microsegmentation tools demand too much manual effort to be practical at scale. Zero Networks’ approach is agentless and automated, enforcing network segmentation without dedicated agents on managed assets or manual policy creation. The rise of AI agents inside corporate environments has added a new dimension to that problem. Employees are running AI

OVH + Proxmox IP range assigning

23 April 2026 @ 10:46 am

I purchased a failover /30 IP range from OVH for my Proxmox host server. Can I use all the IPs in that range and assign them to VMs on the host? ps: im using the default bridge setup Normally, with a /30 subnet, only 2 IPs are usable. However, in OVH’s setup, individual failover / additional IPs are provided as /32 and use the main host IP’s gateway. So does the same concept apply when purchasing a failover IP block (like a /30)? Can all the IPs in that range be assigned to VMs in the same way?

Exchange hybrid in a resource forest scenario: how to create an Exchange Online mailbox without first creating it on-premises and them migrating it?

22 April 2026 @ 5:17 pm

Scenario: Customer with hybrid Exchange environment; all mailboxes are in Exchange Online. Latest Exchange version (SE). Exchange was originally deployed in a resource forest topology, thus each mailbox existed in the resource forest and was linked to a user account in the main forest. Entra Connect syncs both forests and merges the Exchange attributes in the resulting user objects. All mailboxes have been migrated to Exchange Online. Now, when the customer needs to create a new mailbox, they use the following process: The mailbox is created as a linked mailbox in the on-premises Exchange server. The mailbox is them migrated to Exchange Online. From that point on, the mailbox is treated by Exchange as a remote mailbox. It would be a lot easier to simply create a remote mailbox, but it looks like this is not possible: the

How to identify the cause of persistent AdSense Ad Serving Limits on a real-time utility site? [closed]

22 April 2026 @ 3:07 pm

I am currently facing a persistent "Ad Serving Limit" from Google AdSense due to "Invalid Traffic" concerns, and I am looking for help analyzing what on the site might be triggering this. The Situation: The site provides live updates on ISP outages. Because of the nature of the content, users tend to refresh the pages frequently to see if their service has been restored. What I've Checked: Traffic Sources: According to my analytics, the majority of traffic is organic search or direct. I am not using any paid traffic or bots. Ad Placement: I am using standard AdSense Auto-Ads. Content: The content is utility-driven and unique to regional outages. My Questions for the Community: Could the high frequency of user refr

Windows active directory "Domain Controllers" OU applying invisible policies

22 April 2026 @ 12:45 pm

I am currently going somewhat crazy debugging an issue regarding my OU and the way GPO's are applied. I have noticed, that there are invisible undocumented rules being applied to any servers within this built in OU "Domain Controllers". Servers behave differently when they are in that OU as oppose to a different one even when the applied gpo are identical. (i turn off inheritance and link the same ones to both OU). The output of gpresult confirms that the policies are the same. I obviously do not want to have to put non dc servers into my dc OU. The only reference or documentation i can find to this issue is this https://community.spiceworks.com/t/whats-special-about-the-domain-controllers-ou/930162 which is sadly not very helpful and points to a dead link for an article that explains further.

Openvpn config.json structure

21 April 2026 @ 11:28 am

Where can I find documentation for Openvpn's new combined config/state/log file? For a number of years we have been using OpenVPN with the simple key-value pair config files with a .ovpn file extension. An added complication is that we use (short TTL) client certificates as part of the authentication. Automating the certificate refresh is trivial - we just need to update the file referenced in the configuration. However in the most recent MS-Windows version, this is replaced by a JSON file at %APPDATA%\OpenVPN Connect\config.json which appears to combine state and log data along with the CA AND client certificates. The data itself is stored within a JSON encoded string inside the JSON encoded file with added backslashes for good measure. There also seems to be some XML fragments in there too. Since the certificates and keys are embedded in this file, it apparently needs to be regenerated when the client certificate is to be updated. While it is poss

NFS writes over Wireguard S2S tunnel makes TrueNAS hang [closed]

Downloading from my NAS using NFS works for low volume, but during a large file transfer the system hangs and is non-responsive to input using SSH or GUI. After transfer is complete, it will act normal. The system doesn't reboot, or crash. However, when copying files using SFTP/SMB/SCP/Rsync, the problem does not occur, only NFS. fstab: XX.XX.XX.XX:/mnt/BigMomma /mnt/BigMomma nfs auto,hard,intr,vers=4.2,rsize=4096,wsize=4096,noatime,fsc,rdirplus,tcp,actimeo=1800 Running Linux Mint 22.2 NFS to TrueNAS with Wireguard S2S tunnel. Small files work better when operating over WAN/VPN than large sizes. Optimal size is 1396 which is an ethernet packet size minus various overhead, but the IOPS increases. Anyone know the cause?
