Several weeks ago we received a bug report from a customer that said their game was crashing when using IL2CPP scripting backend. QA verified the bug and assigned it to me for fixing. The project was quite big (although far from the largest ones); it took 40 minutes to build on my machine. The instructions on the bug…
You copied the green screen.
I’m entirely convinced that basically every developer alive today heard the adage “dress for the job you want, not the job you have” and figured that, since they always wear jeans and a t-shirt anyway, they might as well apply it to their systems’ architecture. This explains why the stack of every single company I’ve…

Learn how NAT traversal works, how Tailscale can get through and securely connect your devices directly to each other.
I built a device to measure end-to-end input latency, then used it to find out what actually moves the needle.
Lin Clark introduces the Bytecode Alliance, and uses Code Cartoon illustrations to share their vision of a WebAssembly ecosystem that is secure by default, fixing cracks in today’s software foundations. ...

A story from 16 years ago - trust, tech, and a server that had to disappear. They offered me a blank check. I said no.
One of the main reasons some people tend to avoid updating their PCs is that “it makes it slower”. Especially with Windows 10’s Software as a Service approach, where it gets the s…
One of the many enjoyable things about databases is that they generally try to separate how data is represented internally (say on disk) from how it is used. To the point that it has become the norm to not even store the data on the same hardware that is running the queries.

A tale about exploiting KernelCTF Mitigation, Debian, and Ubuntu instances with a double-free in nf_tables in the Linux kernel, using novel techniques like Dirty Pagedirectory. All without even having to recompile the exploit for different kernel targets once.

There’s a great MSR demo from 2012 that shows the effect of latency on the experience of using a tablet . If you don’t want to watch the three minute video, they basically created a device which could simulate arbitrary latencies down to a fraction of a millisecond. At 100ms (1/10th of a second), which is typical of…

The title oversells the content a bit 1 1: Some called it disingenous dickish clickbait. I don't disagree ;-) :
A guide on how to compile the X Window System for iOS
Firefox will monitor available system memory and, should it become that a crash is imminent, Firefox will respond by unloading memory-heavy.
After languishing through the CPU dark-ages (read: Intel trying real hard to keep people on 4 cores so they could charge an arm and a leg for more), the last two years has seen a vertible tsunami of advances in CPU technologies. AMD's introduction of an 8-core CPU (the 1700X) began the rat-race and with both AMD and…
SQL's UNION operation isn't usually regarded as a way to optimize query performance, but in many cases it can be used to achieve massive improvements in speed.
The M1 is the beginning of a paradigm shift, which will benefit RISC-V microprocessors, but not the way you think.
Last year I got certified as an EMT. As part of the training I shadowed an ambulance for a day and assisted with each run. For each patient we treated, we had to fill out a patient care report. A patient care report. (source) EMTs are just one part in a long chain. If they transport a patient to a hospital, the…
