The game industry hit Peak Advice Blog a while ago. Every day I read skim ten articles telling me how to live. Fear not! I would never give you useful advice. This series is about me writing bad code and you laughing at my pain. First Contact Say you have some voxels which occasionally get modified. You regenerate their geometry like so: voxel.Regenerate(); Because you are a masochist, you want to do this on a separate thr..

Don't leave old out-of-date code commented out; just delete it

If you replace code, and commit out the original while you are working, please delete the commented out code before you commit. Code such as: int x = foo() + 1;
// int x = foo() + 2; Becomes pretty unreadable after a time. It makes sense to you while you write it, but in 2 years, and looked at by another developer, it will probably not make any sense. We all use Subversion or git etc., so if you do realize you need the old version ..

I bookmarked An @import-ant Change in Xcode and immediately forgot about it. The gist is to import UIKit to simplify inspecting objects during an lldb session: (lldb) expr @import UIKit Shorten typing by creating aliases in ~/.lldbinit: command alias uikit expr @import UIKit command alias foundation expr @import Foundation

I’m happy to announce a new side project: MyAPRS, a modern iOS APRS application, for radio amateur enthusiasts. I’ve already mentioned APRS on this blog, it will mainly be useful for radio amateurs but can be interesting to RTL-SDR listeners too. The application is built around LevelDB and geo hashing as mentioned in this post blog, it’s a lot faster than using SQLite especially on iOS, SatSat is still using the SQLite cities lookup and you..

So far in this series we’ve seen a lot of motivation and defined basic ideas of what a quantum circuit is. But on rereading my posts, I think we would all benefit from some concreteness. “Local” operations So by now we’ve understood that quantum circuits consist of a sequence of gates $ A_1, \dots, A_k$, where each $ A_i$ is an 8-by-8 matrix that operates “locally” on some choice of three (or fewer) qubits.

FreeBSD is now fully supported on the Raspberry Pi2, makes it a fun small computer to experiment with BSD. If you have a Raspberry Pi 1, you can simply install 10.2-RELEASE image. For Raspberry Pi 2, you need 11.0-CURRENT which is the development branch, images can be found here. dd the image as usual to a SD card, it will be auto resized at first boot. (See growfs_enable="YES") in rc.conf.

A number of times in a crowd I’ve asked how many people enjoy writing SQL, and often there’s a person or two. The follow up is how many people enjoy reading other people’s SQL and that’s unanimously 0. The reason for this is that so many people write bad SQL. It’s not that it doesn’t do the job, it’s just that people don’t tend to treat SQL the same as other languages and don’t follow strong code formatting guidelines. So, of course here’s ....

If you weren’t aware user namepace support was added to Docker awhile back in the “Experimental” builds. But with the upcoming release of Docker Engine 1.10.0, Phil Estes is working on moving it into stable . Now this is all super exciting and blah blah blah, but what I am going to talk about today is how I started running all the containers from my Docker Containers on the Desktop with the new user namespace support. The containers/im....

The officially-supported Ubuntu Phones run pretty old kernels. The Nexus 4 and BQ phones all run v3.4, and the Meizu MX4 runs v3.10. Device kernels typically lag a bit behind since so much effort goes into making them compatible with the hardware, but this posed a bit of a complication since the Click confinement model utilizes features of AppArmor v3, which isn’t even released yet. However, we like to push the envelope here at Canonical, s..

I love really Amazon EMR . Over the years it’s grown from being “Hadoop on-demand” to a full-fledged cluster management system for running OSS big-data apps (Hadoop MR of course, but also Spark, Hue, Hive, Pig, Oozie and more). While Hadoop out of the box supports reading from S3, EMR has a proprietary implementation called EMRFS that has some nice features. For those reasons, it’s really the best Hadoop cluster to use if you’re storin....

On the last episode of From Inside the Box, we found our pickup truck protagonist in the throes of a struggle for survival: not of flesh, but of his very livelihood. Where will he go? What will he do? Will he ever understand why kids love the taste of Cinnamon Toast Crunch™? Find out on this episode eventually…maybe. Just kidding. I don’t plan to talk about any of those things today. Instead, we’re going to talk about poor decisions,..

I’ve been doing a lot of experimenting with neural-style the last month. I think I’ve discovered a few exciting applications of the technique that I haven’t seen anyone else do yet. The true power of this algorithm really shines when you can see concrete examples. Skip to the Applications part of this post to see the outputs from my experimentation if you are already familiar with DeepDream, Deep Style, and all the other latest happe....

This was to be my very first CTF challenge, and what better time to start than during the festive period! Lots of chocolate, alcohol, and mix in a bit of hacking. Perfect to improve my skills and prove my theoretical knowledge hasn’t gone to waste.

We - at the dev-sec.io -team - create Ansible (and Puppet and Chef) roles that harden the security of our Linux-servers. They are meant to be used in production so we try to provide these roles to several different operating systems, including Debian, Ubuntu, RedHat and its derivates. Manually testing the roles on many different systems is a very time-consuming task: You’ll have to set up a virtual machine, update it, install Ansible, ru....

When you work in the software industry, indubitably you will find the (now very famous)BOFH, and Clients from Hell material, where a technical person complains about a client. Whether they asked for an impossible thing or software that doesn’t even make sense, the common mood (or at least what I get from them) is that the client is somewhat stupid, or short sighted. I don’t want to discuss whether the clients are on the right or not, but I ..

In case you missed it, we recently merged a default seccomp profile for Docker containers. I urge you to try out the default seccomp profile, mostly so we can rest easy knowing the defaults are sane and your containers work as before. You can download the master version of Docker Engine from master.dockerproject.org or experimental.docker.com . We even have a doc describing the syscalls we purposely block and security vulnerabilit....
