Understand your Mac and iPhone more deeply by tracing the evolution of Mac OS X from prelease to Swift. John Siracusa delivers the details.
You've got two main options:
package main | |
import ( | |
"net/http" | |
"time" | |
"golang.org/x/time/rate" | |
) | |
// ThrottledTransport Rate Limited HTTP Client |

Writing your own OS to run on a handmade CPU is a pretty ambitious project, but I've managed to get it working pretty well so I'm going to write some notes about how I did it.
This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).
Matrix multiplication is a mathematical operation that defines the product of
Using adb, create a backup of the app using the following command:
adb backup -f freeotp-backup.ab -apk org.fedorahosted.freeotp
This is a compiled list of falsehoods programmers tend to believe about working with time.
Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.
GitHub repositories can disclose all sorts of potentially valuable information for bug bounty hunters. The targets do not always have to be open source for there to be issues. Organization members and their open source projects can sometimes accidentally expose information that could be used against the target company. in this article I will give you a brief overview that should help you get started targeting GitHub repositories for vulnerabilities and for general recon.
You can just do your research on github.com, but I would suggest cloning all the target's repositories so that you can run your tests locally. I would highly recommend @mazen160's GitHubCloner. Just run the script and you should be good to go.
$ python githubcloner.py --org organization -o /tmp/output
I recently happened upon a very interesting implementation of popen()
(different API, same idea) called popen-noshell using clone(2)
, and so I opened an issue requesting use of vfork(2)
or posix_spawn()
for portability. It turns out that on Linux there's an important advantage to using clone(2)
. I think I should capture the things I wrote there in a better place. A gist, a blog, whatever.
This is not a paper. I assume reader familiarity with
fork()
in particular and Unix in general, though, of course, I link to relevant wiki pages, so if the unfamiliar reader is willing to go down the rabbit hole, they should be able to come ou
