Checklist for Verifying a Solana Token Before Buying It

·1 views

Scam tokens on Solana are inexpensive to create and can be made to look legitimate, so the article lays out a read-only verification routine. It stresses that tickers and names are not unique, so the mint address copied from an official source is the only reliable identifier. Readers are advised to check whether mint and freeze authorities have been revoked, whether update authority exists, and how concentrated token holdings are. The guide also recommends confirming that liquidity pool tokens are burned or locked, that the pool is deep enough, and that transactions are reviewed carefully, with small test amounts from a separate wallet. It warns against sites that demand a wallet connection just to display basic token information, and notes that the piece is not financial advice.

Android 'no internet' fault traced to rogue IPv6 router advertisements from a 5G router

A user found that their Android phone showed Wi-Fi as connected but without internet, while other devices worked normally. After isolating the problem, they traced it to a Huawei 5G router (CPE) that was broadcasting IPv6 router advertisements despite being set to LAN-only mode. Disconnecting the device made the phone's issue disappear, and reconnecting brought it back. The author explains that Android's connectivity check depends on reaching its servers, and that stray IPv6 gateway announcements can redirect the phone's traffic into a dead end. The article describes how to detect these advertisements using rdisc6 or tcpdump on the same network segment.

Debugging interviews reward investigation process over a lucky first patch

Live debugging rounds on broken UIs or unfamiliar repos are evaluated on how the candidate investigates, not on how quickly they reach a working fix. Recommended practice is to restate expected versus actual behavior, identify the layer where the fault likely sits, form one testable hypothesis, and run the cheapest probe before editing code. Guides from several interview-prep sources emphasize this sequence over rewriting components or making silent, trial-and-error changes. Interviewers tend to watch how candidates narrow the search space, and a patch that hides the symptom without finding the root cause can score poorly. Some employers restrict AI or external tools during these rounds, so candidates are advised to confirm the rules with the recruiter beforehand.

Why the key skill in AI-driven engineering is knowing when to reject AI proposals

AI tools can now propose architectures, split work into tasks, write code, and prepare deployments, prompting new methodologies such as AWS's AI-Driven Development Lifecycle. The author argues that the decisive question is who actually makes the engineering judgments, not how fast AI can generate output. In this view, the most valuable human contribution is the authority to reject proposals, set constraints, request alternatives, and halt execution. Without that authority, human oversight risks becoming a ceremonial approval step. The piece illustrates the danger with an example of an agent proposing an overly complex design, such as adding Kafka, Redis, and a new microservice for a simple reservation feature.

Home intrusion detector's syn_scan rule could never fire, author reports

A developer building CNDS, a home-network intrusion detector that uses Scapy and five detection engines, ran it on a Raspberry Pi 5 and saw alert volumes of around 45 per hour on day one, with roughly 178 and 336 false positives on two October days. Causes included untrained demo models saturating their scores, critical payload regex rules firing on encrypted traffic, and a monitoring probe generating most remaining alerts. After fixing these, daily alerts dropped to 37 to 63 with none rated high or critical. A red-team test then revealed that the syn_scan rule had a contradictory condition that made it impossible to trigger, since every SYN packet also counts as a forward packet. The author fixed the rule and made it critical, though a SYN flood test still produced no alert, prompting further investigation.
