New top story on Hacker News: Ask HN: Has the Apple Silicon excessive disk read/write issue been fixed?
Ask HN: Has the Apple Silicon excessive disk read/write issue been fixed?

This was a discussion when M1 macbooks were launched, and Apple supposedly addressed it in an OS update (macOS 11.4). But I'm seeing really high read/write numbers. I'm aware that SSD lifespans are long and TBW spec is pretty generous. Still, compared to my linux machines, this seems extraordinarily high. On my newish M1 MBA, with the latest updates, with barely any use, 98%+ sleep, I'm seeing about 3 to 5 GB reads per day and 2 to 4 GB writes per day. Latest report from smartctl. ---------------------------------------------------- === START OF SMART DATA SECTION === SMART overall-health self-assessment test result: PASSED SMART/Health Information (NVMe Log 0x02) Critical Warning: 0x00 Temperature: 27 Celsius Available Spare: 100% Available Spare Threshold: 99% Percentage Used: 0% Data Units Read: 716,195 [366 GB] Data Units Written: 616,232 [315 GB] Host Read Commands: 9,108,273 Host Write Commands: 6,947,397 Controller Busy Time: 0 Power Cycles: 95 Power On Hours: 5 Unsafe Shutdowns: 11 Media and Data Integrity Errors: 0 Error Information Log Entries: 0 ---------------------------------------------------- M1 Air 16GB 1TB.

New top story on Hacker News: Ask HN: Books on designing disk-optimized data structures?
Ask HN: Books on designing disk-optimized data structures?
6 by memset | 4 comments on Hacker News.
Are there canonical books, resources, or readings for how to design data structures that will be primarily read and written to a disk rather than memory? Most of what I learned in school about big-O assumes that, for example, random access is O(1). However, random disk reads are really slow due to spacial locality. People who write databases obviously have solutions to this problem - for example, DuckDB is based on a number of papers that have come out over the years on this topic. If I wanted to design, ie, a tree structure which was intended to be read/written from a disk, are there general principles or patterns the have been developed to take advantage of locality of reference, minimize random reads, or decrease the overhead of writes, that I could familiarize myself with? What is the CLRS for disk?

New top story on Hacker News: Show HN: TaskTXT, plain text task-timing notepad
Show HN: TaskTXT, plain text task-timing notepad
11 by trafnar | 7 comments on Hacker News.
I built TaskTXT.com based on my experience timing my tasks. I found that committing to a task before I start helps with my focus, and guessing how long it will take, then timing it prevents me from wanting to give in to distractions because I'm "on the clock". Video Overview: https://www.youtube.com/watch?v=HOYO0c_D6w0 There's also a Mac app which you can download here: https://ift.tt/06skDB7 Video overview of the Mac app: https://www.youtube.com/watch?v=qMs-V5v5gZY But I didn't want the tool to be distracting, so its based on plain text. That means the UI is very familiar and you can use it for generic notes in any structure you like. When you work in TaskTXT you are working directly on its data format, I made a video about this concept here: https://www.youtube.com/watch?v=kZdBgVZn5NI I think this tool is uniquely suited for programmers, so I'd be interested to hear any feedback about the product, or its viability as a business.

New top story on Hacker News: Show HN: IPDetective – An API for IP bot detection
Show HN: IPDetective – An API for IP bot detection
9 by AndrewCopeland | 4 comments on Hacker News.
IPDetective collects data from about 60+ different sources such as official cloud provider endpoints and public VPN/Proxy/Tor/Bot net lists. Then aggregates this data into a fast and easy to use API that can be integrated into applications or scripts easily. IPDetective started as a hobby project for my other hobby projects :) and I decided to wrap a simple website around and offer it as a service. Let me know what your thoughts, if you find value in this service or if you have any feature requests.

Ask HN: Should I be panicking about jobs in Europe?

I contract with a lot of European game studios. I've noticed many contracts were terminated suddenly including my retainers for cost reasons. Is the energy crisis that bad ? Are multiple industries affected right now or is it just planning ?
