A vulnerability in the text rendering subsystem of Cisco TelePresence Collaboration Endpoint (CE) Software and Cisco RoomOS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.

This vulnerability is due to insufficient validation of input received by an affected device. An attacker could exploit this vulnerability by getting the affected device to render crafted text, for example, a crafted meeting invitation. As indicated in the CVSS score, no user interaction is required, such as accepting the meeting invitation. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Phonchain is a mobile-native blockchain secured by real smartphones via a consensus mechanism called Proof-of-Phone Secure (PoP-S4).

Instead of relying on hashpower or stake, Phonchain uses real device participation as the primary source of security, with up to 30,000 independent mobile participants per block.

The network is currently live with: - Public explorer - Gateway/Core node implementation - Bootstrap/seed endpoints - Android wallet under Play Store review

Canonical network anchors: https://github.com/Phoncoin/phoncoin

Reference node software: https://github.com/Phoncoin/phonchain-node

Network explorer: https://explorer.phonchain.org/explorer

Technical feedback is welcome.

Apologies if this is old news to everyone, but perhaps the hive mind knows the answer. I was watching a youtube video "The most complex model we actually understand" by Welch Labs and heard the story about the researcher who left a model training when going on vacation, which then learned to generalize after thousands of training steps. But when I try to look up the name of the discoverer it has not been made public, which seems a shabby way to treat someone. What's the real story?

Hi HN — I’m an indie maker building Seedance AI. It helps people create short videos (and images) from text prompts and reference photos. I tried to keep it simple: fast templates, predictable credit pricing, and downloadable results. It’s still early, and I know there are rough edges. I’d really appreciate honest feedback on what feels useful, what feels confusing, and what I should improve first. Happy to answer technical or product questions.

I’ve always used 8.8.8.8 or 1.1.1.1, but I realized I didn't actually understand how the resolution chain worked under the hood. To fix that, I built a DNS resolver in Go that performs true iterative resolution from the root servers down, with no upstream dependencies.

Unlike a simple DNS forwarder, this server doesn't just "ask someone else." It implements the full hierarchy: Root → TLD → Authoritative → Final Answer.

Key Technical Challenges I tackled:

Iterative Navigation: Setting RecursionDesired = false so that upstream servers treat the project as a peer resolver.

The "Glue Record" Problem: Implementing sub-resolution where the resolver has to pause the main query to resolve a nameserver's hostname before it can continue.

TTL-Aware Concurrency: Using sync.Map for a thread-safe cache that automatically respects record expiration.

State Management: Handling referrals and avoiding infinite loops in heavily nested zones.

Architecture: The server is built using raw UDP sockets and the dnsmessage package for packet parsing. It handles thousands of concurrent requests using Go’s concurrency primitives.

UDP Listener: Standard net.PacketConn loop.

Resolver Engine: Recursive logic that walks the hierarchy starting from A.ROOT-SERVERS.NET.

Local Overrides: A JSON-based configuration for authoritative local records (useful for dev environments or ad-blocking).

I’d love to hear from anyone who has worked on DNSSEC or handled high-traffic DNS infrastructure. What are the common pitfalls when moving from a "toy" resolver to a production-grade one?
