Apple's new Processor Trace instrument is incredible

news.ycombinator.com Victor Wynne 2025-11-18 09:42:28

Apple’s latest addition to Xcode, the Processor Trace instrument, is one of those features that sounds pretty mundane until you actually try it. Then you realize it’s exactly what you’ve been needing for the performance mysteries that eat up hours upon hours of your development time. If you’ve been developing apps for a while, this story will sound very familiar. Your app runs fine in testing, but then users complain about performance issues or excessive battery drain. You fire up Instruments,

According to German news outlet Heise, notable progress has been made regarding the counterfeit Seagate hard drive case. Just like something out of an action movie, security teams from Seagate's Singapore and Malaysian offices, in conjunction with local Malaysian authorities, conducted a raid on a warehouse in May that was engaged in cooking up counterfeit Seagate hard drives, situated outside Kuala Lumpur. During the raid, authorities reportedly uncovered approximately 700 counterfeit Seagate

Dropbox announces new gen server hardware for higher efficiency and scalability

Fourteen years ago, Dropbox took its first steps toward building its own hardware infrastructure—and as our product and user base has grown, so has our infrastructure. What started with just a handful of servers has evolved into one of the largest custom-built storage systems in the world. We've scaled from a few dozen machines to tens of thousands of servers with millions of drives. That evolution didn’t happen by accident.

The old Macintosh HD hard drive icon, for years represented by a facsimile of an old spinning hard drive, has been replaced with something clearly intended to resemble a solid-state drive (the SSD in your Mac actually looks like a handful of chips soldered to a circuit board, but we'll forgive the creative license).

More than two hard disks in DOS

news.ycombinator.com Posted On 2025-12-12 11:19:27

Investigating the rather odd behavior of the Microsoft OS/2 1.21 disk driver led me to Compaq and their EXTDISK.SYS driver. While experimenting with various setups, I realized that DOS versions older than 5.0 do not support more than two hard disks exposed by the system’s BIOS, and will in fact quite likely hang early during boot-up if there are “too many” hard disks. This seems to have been one of the many things that “everyone knew” back in the day, similar to the fact that DOS versions older
