Sending Web MIDI data to vintage synthesizers often crashes the classic hardware because fast transfers overwhelm their slow processors and strict 31.25k baud limits, a problem worsened by cheap USB cables. To prevent this, developers must implement deliberate sender pacing, software flow control, and custom JavaScript parsing to properly manage the SysEx communication.

An anonymous GitHub account has published an archive of undisclosed zero-day exploits, encouraging the community to responsibly report the flaws for CVE credit. The creator stated that this mass release of proof-of-concept code and vulnerability research is intended to attract new talent into the cybersecurity field without enabling malicious abuse.
CommentsFintech Engineering Handbook
2026-06-27Readers are heavily critiquing a newly published Fintech Engineering Handbook, arguing that its guidance on handling monetary data is overly simplistic and sometimes fundamentally flawed. The resulting discussion centers on a debate over whether software should strictly use integers to prevent floating-point errors in financial transactions, or if floating-point numbers are acceptable for complex analytical calculations like options pricing. Commenters ultimately conclude that the correct engineering approach depends heavily on the specific fintech domain, noting that custodial systems require extreme precision while risk-metric systems can safely rely on floats.
CommentsLibdeflate has introduced a deliberately impractical DEFLATE level 13 compression option that exhaustively searches encoding choices to maximize size reduction. Although it produces standard output, it runs 56.4 times slower than level 12 for a marginal 0.134% size improvement, making it suitable only for static data compressed once and distributed repeatedly.
