Ask HN: Has the Apple Silicon excessive disk read/write issue been fixed?
32 by cool_hw | 17 comments on Hacker News.
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.

Ask HN: What's Happening at Cloudflare?

I seem to be bombarded by multiple Cloudflare posts on Hackernews lately. Is there something else I should know? Is this 'innovation month' at Cloudflare or something? All these were posted in the last few weeks! ↪ https://ift.tt/wB3MbGD https://ift.tt/CR4U2sn https://ift.tt/6c8qbQo https://ift.tt/d6TAx29 https://ift.tt/qCfaIhH https://ift.tt/TuK42y6 https://ift.tt/uQvXN58 https://ift.tt/AJfZKyX

New top story on Hacker News: Ask HN: Books on designing disk-optimized data structures?

Ask HN: Books on designing disk-optimized data structures?
8 by memset | 5 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?

Ask HN: Why is everything a SaaS product?
7 by kevivni | 6 comments on Hacker News.
I understand the advantages of Saas - transparent updates, cloud based, redundancy, subscriptions, scaling, unicorns etc. Why don't we have more businesses following the JetBrains model specially if the product is not a service that needs to run 24/7. I buy the product once and use it for perpetuity. If I want updates, I pay more. As a consumer, my data does not leave my perimeter, my data is not sold or used for ads and I am not hooking into a subscription that I am going to forget soon. 1) Personal photos and videos backup and viewer. - Just give me a cheap cloud for backup and a desktop app for viewing. 2) Personal budget - Just give me a desktop app that connects to my different accounts and gives me overview.

New top story on Hacker News: Ask HN: “lofi” File Share for personal, team usage

Ask HN: “lofi” File Share for personal, team usage
6 by dv35z | 0 comments on Hacker News.
The Team File Share. AKA “How is this still an unsolved problem?” In 2004, I worked at a bank, and our team had a “P:/“ drive. It was a networked file share (probably Windows Server), mounted on everyone’s computer. Turns out, several members of the team were meticulous organizers, and would even leave notes at top-level folders - an index & guidance on what to put there, how to name files, and so on. Loved it, and did my best to keep things tidy and easy to find. What’s great is the whole file structure was browsable in a Browser (eg visiting p://marketing/events/2022-09-05 - Lunch & Learn/ would show the Apache-style index page, containing html links to files in that directory. Sharing a file with a colleage was as simple as sending the URL. When we wanted to share files externally, we had an FTP fileshare you could drag files to, and the URL was also predictable (https://ift.tt/YMyQjqG) I was brainstorming today, and was wondering, what’s a modern setup of the above? I’ve been experimenting with Dropbox & Google Drive with “fresh eyes”… so many frustrations, especially on iOS. It’s either you’re using their apps directly (annoying UI for both), or iOS File.app. But half the time, Dropbox isn’t “connected” (?) - in today’s case I had to update the Dropbox app & re-authenticate thru their app before the files were available in Files. It all seemed so silly of a disruption from such an essential tool of my file: my digital files! Are there any “so simple, it feels like we are in a 2004 office” file share solutions? A few requirements (feel free to m suggest other (need/wants), in the comments)… - I can access my files on my computer (Finder, terminal) and phone (iOS, using Files.app) - Files are automatically backed up (hourly/daily/weekly) - I can read & write to files when there is no network service (eg while in NYC subway), and they’ll sync back up (SyncThing?) - Private files are secure. On a personal fileshare, I ought to be able to store health records, financial records, sensitive notes & files. The “me” stuff. The family drive would have kids health records and so on. (the first solution that came to mind is “encrypted, password protected disk image, hosted on a fileshare in a VPC, only accessible when logged into VPN; and then accessible thru iOS Files.app?) For Work, I ought to have “my drive” (eg example.com/~me/projects/, and “team drive”, also a private work area m (pay statements, notes from 1:1s / boss, etc) - Fileshare. I ought to be able to be able to drag a file over to pub-fileshare, and it’s accessible to anyone with the URL. Or protected-fileshare, where certain folders have passwords (or some other securing mechanism, since who wants to remember more passwords…? What’s the state of the art / tool stack of a “lofi” fileshare setup? Imagine you were setting this up for (1) yourself (2) a best friend (3) family (4) small work team What solution might actually last 10+ years?

Hacker Stations – Tech workspace setups to get inspiration from
19 by poushkar | 8 comments on Hacker News.
I really like the "workspace porn" and been frequenting various blogs and communities with workspace setups. It's inspiring and interesting to see how other people organize their workspaces and achieve focus and comfort. And while it's also interesting to see random setups from people with different backgrounds, I especially like to see setups from developers and tech professionals like myself. That's why I decided to start the blog dedicated solely to such setups. I hope some HN visitors will appreciate it, too.

Ask HN: Should a German founder with a green card set up a holding company?
15 by ck_one | 11 comments on Hacker News.
In Germany, founders usually hold their shares in a holding company. This has the benefit that at an exit event you only get taxed 5% if you keep the exit money in the holding company. You can make investments (angel, real estate etc) from your holding company. Only when you withdraw money from the holding company you have to pay personal tax. I am curious do US founders do something similar? Does my situation change because I own a Greencard and will incorporate in the US? Most importantly has anybody recommendations for good German/US lawyers?
