The log files of the Debian system are usually stored in the /var/log
directory. To effectively manage these log files and avoid taking up too much disk space, you can clean or compress them by following methods:
Method 1: Use the logrotate tool
The Debian system has built-in logrotate
tool, which can automatically manage the rotation, compression and deletion of log files. Its configuration file is located in /etc/logrotate.conf
, and the specific log file configuration is located in /etc/logrotate.d/
directory.
You can run logrotate
manually with the following command:
sudo logrotate /etc/logrotate.conf
Or, rotate for a specific service (such as rsyslog):
sudo logrotate -f /etc/logrotate.d/rsyslog
The -f
option means enforcement and will run even if the configuration file does not expire.
Method 2: Manually clean the log files
If you need to manually clean the log files, you can use rm
(delete) or gzip
(compress) commands. For example, delete the /var/log/syslog
file:
sudo rm /var/log/syslog
Compress /var/log/syslog
files:
sudo gzip /var/log/syslog
Important: Before deleting or compressing log files, be sure to carefully consider their impact and make sure that the necessary information has been backed up. Log files may need to be kept for some time to meet compliance requirements or for troubleshooting. It is recommended to use the logrotate
tool first, as it provides a safer and more reliable log file management mechanism.

The duration of the airdrop dividend is uncertain, but the LayerZero, StarkNet and ZK ecosystems still have long-term value. 1. LayerZero achieves cross-chain interoperability through lightweight protocols; 2. StarkNet provides efficient and low-cost Ethereum L2 expansion solutions based on ZK-STARKs technology; 3. ZK ecosystem (such as zkSync, Scroll, etc.) expands the application of zero-knowledge proof in scaling and privacy protection; 4. Participation methods include the use of bridging tools, interactive DApps, participating test networks, pledged assets, etc., aiming to experience the next generation of blockchain infrastructure in advance and strive for potential airdrop opportunities.

Ordinary investors can discover potential tokens by tracking "smart money", which are high-profit addresses, and paying attention to their trends can provide leading indicators. 1. Use tools such as Nansen and Arkham Intelligence to analyze the data on the chain to view the buying and holdings of smart money; 2. Use Dune Analytics to obtain community-created dashboards to monitor the flow of funds; 3. Follow platforms such as Lookonchain to obtain real-time intelligence. Recently, Cangming Money is planning to re-polize LRT track, DePIN project, modular ecosystem and RWA protocol. For example, a certain LRT protocol has obtained a large amount of early deposits, a certain DePIN project has been accumulated continuously, a certain game public chain has been supported by the industry treasury, and a certain RWA protocol has attracted institutions to enter.

The coordinated rise of Bitcoin, Chainlink and RWA marks the shift toward institutional narrative dominance in the crypto market. Bitcoin, as a macro hedging asset allocated by institutions, provides a stable foundation for the market; Chainlink has become a key bridge connecting the reality and the digital world through oracle and cross-chain technology; RWA provides a compliance path for traditional capital entry. The three jointly built a complete logical closed loop of institutional entry: 1) allocate BTC to stabilize the balance sheet; 2) expand on-chain asset management through RWA; 3) rely on Chainlink to build underlying infrastructure, indicating that the market has entered a new stage driven by real demand.

In the ever-changing virtual currency market, timely and accurate market data is crucial.

The most popular tracks for new funds currently include re-staking ecosystems, integration of AI and Crypto, revival of the Bitcoin ecosystem and DePIN. 1) The re-staking protocol represented by EigenLayer improves capital efficiency and absorbs a large amount of long-term capital; 2) The combination of AI and blockchain has spawned decentralized computing power and data projects such as Render, Akash, Fetch.ai, etc.; 3) The Bitcoin ecosystem expands application scenarios through Ordinals, BRC-20 and Runes protocols to activate silent funds; 4) DePIN builds a realistic infrastructure through token incentives to attract the attention of industrial capital.

In cryptocurrency trading, stop loss and take profit are the core tools of risk control. 1. Stop loss is used to automatically sell when the price falls to the preset point to prevent the loss from expanding; 2. Take-profit is used to automatically sell when the price rises to the target point and lock in profits; 3. The stop loss can be set using the technical support level method, the fixed percentage method or the volatility reference method; 4. Setting the stop profit can be based on the risk-return ratio method or the key resistance level method; 5. Advanced skills include moving stop loss and batch take-profit to dynamically protect profits and balance risks, thereby achieving long-term and stable trading performance.
