If you use Mixxx (Free, open-source DJ software) then you'll always be safe from hostile Spotify takeovers ;).

Mixxx developer here. Thanks for the review, Dan! We indeed have our work cut out for us :).

One additional note, Mixxx is "open source" which means that anyone can get involved and make improvements or add features. If you've ever made a website with HTML/Javascript then you already know enough to create your own MIDI/HID device scripts to totally customize your workflow.

For more information on how to contribute check out our wiki: http://mixxx.org/wiki and our project on GitHub: http://github.com/mixxxdj/m...
Please get in touch if you're interested in helping out!

Thanks for the review, Dean! I'm a Mixxx developer and am happy to answer any questions.

Re: How CockroachDB Does Distributed, Atomic Transactions

RJ Ryan — Wed, 02 Sep 2015 16:17:50 -0000

What do you mean by "lockless" (since there are a variety of ways to define it)? I'm probably misunderstanding something, but the switch and write intents seem like locks to me. "The switch cannot be concurrently accessed – reads and writes of the switch are strictly ordered." "As a final rule, there can only be a single write intent on any key. If there were multiple concurrent transactions, it would be possible for one transaction to try to write to a key which has an active intent from another transaction on it."

Mixxx lead developer here. Thanks for the mention of Mixxx!

Just a quick note that we've got our latest release, Mixxx 1.12.0 right around the corner. We're planning a beta release April 1 and a final release May 1.

After over a year of development, we're packing a lot this time around:

* 4 decks (including 4 vinyl control inputs if you want to use 4 turntables)
* Master sync
* Key detection and pitch shifting (independent of tempo) for harmonic mixing.
* 4 effect units for built-in effects (this also introduces all the necessary plumbing for LV2/VST, effect send/receive, and advanced chaining in a future release)
* beatloop rolls (now you can create beatloops and automatically jump to where the track would have been if you hadn't enabled the loop when you release it)
* Resizable skins (yes, finally!)
* Vinyl control deck passthrough (switch to real vinyl temporarily)
* Auxiliary inputs that pass through to the master mix.
* Custom key notations (pick between traditional, OpenKey, Lancelot notation or a custom one)
* Beat jumping and loop move
* multiple library folders
* mono output and input support (easily do the Master/Headphone trick on one stereo output)

Along with over 100 performance, quality and usability improvements.

You can monitor our progress towards 1.12.0 here:
https://launchpad.net/mixxx...

And, if you are a programmer you can join us and add whatever features you want! Mixxx is a community effort created by DJs, for DJs.

All of our code is on GitHub here: https://github.com/mixxxdj/...

Re: Keylock In DJ Softwares Compared: Serato DJ, Traktor Pro, Virtual DJ

Mixxx 1.12.0 will release with the RubberBand algorithm for time stretching and pitch shifting (previously we were using SoundTouch). http://breakfastquay.com/ru...

RubberBand has a command line tool you could use to test it out. It's quite good.

Mixxx lead developer here. Great writeup! I would have loved to see how the Queen Mary University key detector stacks up.

http://vamp-plugins.org/plu...

It's also open source and available as a VAMP plugin. Mixxx is adding key detection in Mixxx 1.12.0 and will have the option of using KeyFinder or the QM key detector. You could try out the QM detector in the latest alpha releases of Mixxx 1.12.0.

The text in the snippet is just the text in the <meta> description tag on the Apple page.

This is likely just referring to the previous launch of the 15" retina macbook pro and the updated 13/15" macbook pro models from earlier this year.

Re: Review: Mixxx 1.10 DJ Software

RJ Ryan — Fri, 10 Aug 2012 14:19:12 -0000

Hi there,

It's hard to quantify. We have a core team of probably 5 or 6 people and a community of 100+ contributors who send us patches infrequently. The problem is that we're all volunteers working in our spare time so maybe 5-6 people's spare time adds up to about 1 full time engineer.

Re: Review: Mixxx 1.10 DJ Software

RJ Ryan — Thu, 09 Aug 2012 10:34:19 -0000

Yup -- that's right. There are 37 hotcues per deck/sampler we just don't have enough room in the GUI to put buttons for them. They are addressable via HID/MIDI or keyboard control.

Re: Review: Mixxx 1.10 DJ Software

RJ Ryan — Thu, 09 Aug 2012 10:32:09 -0000

Hi there,

Good idea! Mixxx already has a pretty advanced scripting interface based on Javascript/ECMAScript. We built this for supporting MIDI controllers -- all you need to make a super-advanced preset for a MIDI or HID controller is to write some simple Javascript. We're looking to expand this into a general script interface for use even when you don't have a MIDI controller.

We're building an effects framework that will include the ability to write your own effects plugins. Our sound-decoder system is already modular and supports audio decoder plugins.

As for an actual native-code plugin system (instead of Javascript) for extending Mixxx's functionality I think since Mixxx is open-source there is much less of a need for this relative to proprietary software where the code is not available. We're a very welcoming community and instead of putting your awesome new feature in a plugin, we'd rather you build it directly into Mixxx so that every Mixxx user benefits from the new hotness. To some extent this is how Mixxx got where it is today -- most new features are written by people who are just scratching their own itches.

Hi there (and thanks Markkus for the warm review) -- Mixxx's lead developer here. If you're interested in Mixxx, here's what we've got coming down the pipeline:

Mixxx 1.11.0 is in beta! We are getting ready to release the stable version very soon. You can download the beta here:http://mixxx.org/forums/vie...

Among the new improvements:

* Massively improved beat detection (like.. 10x better than 1.10.1! and it can handle non-constant-tempo beatgrids)

* 3-band colored waveforms

* HID controller support -- support for HID script (our scripting system for MIDI controllers now adapted for HID) and preliminary support for a lot of HID devices (Pioneer CDJs, Eks Otus, WiiMotes, Sony Sixaxis, Traktor Kontrol F1, etc.).

* Set-log / history feature so you can keep track of your set lists automatically

* Revamped/improved AutoDJ -- (yea, I know.. not that interesting to the DJTT crowd ;) )

* Point-and-click MIDI mapping -- the old MIDI learn wizard is gone and the new one is point-and-click based.

* Advanced search -- try a search query like "artist:'Com Truise' bpm:80-110 played:>5" and you get tracks whose artist matches 'Com Truise' and with a BPM between 80-110 and that you have played greater than 5 times.

And to respond to Markkus's comments -- 4 decks and an effects system are in the works and on track for being included in Mixxx 1.12. (also a master-sync system, built in key detection, and more!)

Hope you like it! As always, please hit up our

Re: Google Music: The Best Service That Nobody’s Using

RJ Ryan — Mon, 27 Feb 2012 16:07:54 -0000

"there is absolutely no way Google could determine if your tracks were illegally downloaded or simply ripped from your own physical discs"

Pedantic stickler note: This isn't true since every encoding of a particular rip varies based on the type and version of encoder used, the computer used, and manufacturing defects in the source material (CD, vinyl, etc.). Beyond this, most ripping groups add their own custom metadata or watermarks which make a simple fingerprint of the file "unique". If you upload a copy of music that is bit-for-bit identical to one known to be produced by a pirating group then you can infer the provenance of that file.

What you cannot do is prove that the user doesn't own rights to the song/album in question via other means -- e.g. they bought the CD but it was more convenient to pirate it rather than rip it.

Re: Facebook was never a big geek site (Google+ needs to pass more than the geek test)

RJ Ryan — Wed, 06 Jul 2011 10:14:51 -0000

I invited all of my friends (~50 non-technical people) and they are all using it regularly.

Also you say people like it because everyone (e.g. parents, acquaintances, etc.) isn't on it. That's a Facebook-only problem -- you don't want to put your mom in your friend-bucket. This is actually a non-problem on Google+ because all sharing is targeted. That's what makes it very compelling -- it models your real life social interactions.
