mathnode··on Ideas for Startups (2005)
No, "do one thing well".

However with a premium delivery purchase, the drone will also work as an 'applicator'.

mathnode··on Ideas for Startups (2005)
A regional Condom Drone Delivery Service.

- "Rubber up 'bruv", in the UK.

- "Rubber a brother" for the US.

Expand to CAAS (contraceptives as a service) when applying for second round, pre-ipo.

mathnode··on Continuous MySQL backup validation: Restoring backups
Thanks
mathnode··on Advanced Data Structures
I take it solutions by students are mostly done in Python now?
mathnode··on Continuous MySQL backup validation: Restoring backups
Thanks, how big is a single instance? All out to a single file?
mathnode··on Continuous MySQL backup validation: Restoring backups
Is the FB branch version of mysqldump still single threaded? How do you cope with that?

I currently "fake it", using "START TRANSACTION WITH CONSISTENT SNAPSHOT", with multiple mysqldump processes running, where I can't get mydumper deployed.

mathnode··on Gh-ost: GitHub's online schema migration tool for MySQL
Percona are flogging a dead horse called "Oracle" while at the same time basically being an Oracle subsidiary without being Oracle, but it's basically Oracle wrapped in scary perl scripts with backported features from better forks.

If you were to meet me in person I would just say "Fuck Percona/Oracle and their shitty shit".

mathnode··on Gh-ost: GitHub's online schema migration tool for MySQL
The README on github has a better explanation of how it works, and as I suspected, this could also be achieved with Tungsten Replicator.

Good job though. Anything that helps people move away from Percona and their "tooling" is a plus to me.

mathnode··on Natron: Open-source compositing software for Mac, Windows and Linux
Blender is one of many node-based compositors. They became a thing in the late 90's. Everyone is just copying what nreal, Discreet, and Avid did.
mathnode··on Natron: Open-source compositing software for Mac, Windows and Linux
Nuke is essentially a successor to Shake, which was basically a cheaper alternative to whatever Sony, Avid, and Qauntel were pushing way back when.

Natron is a node-based compositor, there have been many over the last few decades.

Another open source node-based compositor is Blender which also has an non-linear editor.

Lots of compositor customers just buy Nuke, Fusion, AE, etc to process sequences through different commercial plugins; having an open source wrapper to run and control the plugins is an excellent alternative.

This is Packaged up neat enough in a manner that ensures fewer awkward questions at airport security.
mathnode··on Terrible choices: MySQL (2014)
Since Streaming Replication and pg_basebackup was introduced in PostgreSQL; I generally wouldn't.

MariaDB 10 and onwards has some fun features though if you are stuck with it. The CONNECT and TokuDB storage engines are very useful and interesting. Parallel, Multi-source, and GTID replication with multiple domains is very easy.

mathnode··on Terrible choices: MySQL (2014)
I have been a mysql dba for years; I don't recommend mysql for anything or anyone. Oracle are adding glitter, not polish.

If you still really want or need mysql please do check out mariadb, even old versions like mariadb 5.3 onwards added a lot of features and fixes for old problems from before the Sun acquisition (Remember, MariaDB was forked with the Sun buyout or MySQL AB, not Oracle). It's not entirely a drop in replacement though, read the manual and test your configs!

What MariaDB/MySQL is still really good at, is scaling horizontally pretty quickly, just be sure to separate out different schema workloads into different server instances, and don't make your schema overly complex. Not that it can get too complex anyway with SQL/PSM heh-snort snort.

Want to scale bigger and faster, and maybe with an even more highly tuned dataset per-cluster? Cassandra. Lots of Oracle and IBM business is being slurped up by Cassandra and Datastax.

Want mixed database workloads and all the RDBMS management, SQL and PL goodies? PostgreSQL.

mathnode··on Driverless lorries to be trialled in UK
Hopefully driverless lorries wont overtake each other on dual-carriage ways.
mathnode··on Linux Mint downloads (briefly) compromised
The poor saps who have it recommended to them or installed for them.

It's a desktop environment theme at best, and could be packaged as such. Maintaining a distro for general consumption (it's pitched to new users as "Windows like"), is very hard work and carries a lot of responsibility.

mathnode··on Ask HN: What's going on at IBM?
Not completely the same, but I meet with regional aws staff a few times a year including product managers.
mathnode··on Ask HN: What's going on at IBM?
From my lowly developer point of view.

Power may be a bit quicker than Intel, but it's unfamiliar to many. Nvidia is breaking new ground, it's sexy, accessible, and cheaper.

On the software side it's a similar story. Why use their unknown proprietary cloud stuff when I can just make use of the plethora python/julia/clojure/R stuff? AWS is fancy and ever expanding, Softlayer is a PITA.

mathnode··on MariaDB Raises $9M More, Michael Howard Named New CEO, Monty Widenius CTO
MariaDB plans for version 10.2:

mathnode··on Adobe tries to strong-arm me into keeping Creative Cloud
Developers on macs, you have lots of alternatives! Affinity Designer and Pixelmator, for vector and raster graphics. Apple Motion is still in the app store for compositing.
mathnode··on DataGrip 1.0 (formerly 0xDBE): A New IDE for DBs and SQL
Datagrip will work, so long as you have compatible JDBC driver.
mathnode··on Open source software for developing world hospitals
Imagine if this got better than systems that are on offer when this requirement goes out to tender for the NHS institutes in the UK?

So long as it doesn't do over night batching, it's already decades ahead. I wish I was joking.

mathnode··on Apache Kafka 0.9 is released
The only other beast of similar nature that appears occasionally I can think of, is Onyx. Which seems pretty cool.

Anyway,Kafka Connect will provide what probably most people are looking for in Samza.

mathnode··on MariaDB 10.1 can do 1M queries per second
Which aspect in particular do you wish to emulate from TokuDB in PostgreSQL?
mathnode··on MariaDB 10.1 can do 1M queries per second
My favourite, TokuDB has online DDL. Which is a welcome change to the MySQL ecosystem.

I am pretty sure the only other engines that support online DDL is Sybase and DB2.

Online DDL generally means lock free DDL operations.

Not even Oracle, MSSQL, or Postgresql do online DDL. But at least they have transactional DDL, even if it isn't entirely lock-free all the time.

Compared to InnoDB/XtraDB; TokuDB lacks foreign key support, because this was worked into InnoDB years ago because the MySQL server layer doesn't support any kind of constraints. I am hoping for MariaDB to start implementing more modern SQL features which would this be available in supported storage engines.

A reminder than Affinity Designer exists,

And it's just swell.

mathnode··on Creating a Unix Application Using the Win32 API (1998)
After Avid acquired Softimage 3D from Microsoft, the next version, coined Softimage XSI, had a Linux version available through MainWin. It was diabolical. But it limped on; over the years maintaining an extremely tight version range of external library dependencies. Last version I used required Fedora 7 x64, a minor-version specific driver for FireGL/Quadro that just so happen to be on the CD that came with the HP XW workstation. Bite the head off a chicken, and boil snails with lizard tails, let it cool to room temperature, re-boil and simmer throughout use of softimage.

Softimage is now declared dead by their current owners, Autodesk.

mathnode··on Making Cython as easy as Python
Yup. Cytoolz. Some notes on performance of Cytoolz:

mathnode··on Fedora 23 Beta released
Long time Fedora user here. Love it. It's so clean and generic. No fuss, no bullshit.

The workstation build they have worked on for a few releases now was a real boon.

Just like OSX, I just get on with it, and I don't notice it.

mathnode··on OS X El Capitan GM Candidate available
Public transit info, for the dev on the go! And I guess the extra language support is always good for our South East brethren.

Split view support sounds good. Let's see how it measures up against things like Spectacle and Amethyst.
