snw··on Parity, a numbers puzzle game
after level 50 there are black & white tiles that increase/decrese the value when you step on them.

Not so easy anymore

snw··on SmartDataCenter and Manta are now open source
opensourcing sdc is great, but opening up manta for everyone is huge! Thanks!
snw··on Is ZFS a suitable replacement for other Linux filesystems?
try one of the Illumos distributions like OmniOS or SmartOS. The legacy of open-solaris is well and alive.
snw··on Building packages at scale
Interesting article with historical context that goes 10 years back and many detailed insights!

Using pkgsrc at our company since a bit over a year has been excellent thanks to the great work from jperkin and many others. It is one of the tools i wish i had known earlier about since it makes life sooo much easier.

- Quartly stable releases mean that you have recent software most of the time.

- It is available on many platforms (OS X, Linux, SmartOS/Illumos, the BSDs, ...) so you can use the same packages on all your systems.

- Very easy to build binary packages of custom software / custom options / different versions / add your own patches. This is critical for most sysadmins/ops people - and if you ever tried to setup koji for CentOS you will love the simplicity of pkgsrc...

In my opinion pkgsrc is the most underappreciated "devops"-tool out there. It gave us much more control over our software stack and reduced the amount of work we had to put in to archive our goals.

I also expect the effort to reduce bulk-build times to further improve the software quality of all things in pkgsrc. Instead of weekly/daily bulk-builds (depending on the platform) it will be possible to have 4 or more reports a day. This quick feedback will make determining if/which commit broke/fixed something more immediate. Great stuff!

actually the "src" in pkgsrc means that you have the choice of using binary packages (pkg) or building from source. The best of both worlds!

Give it a try, you might like it (because it rocks!)

Thats a very valid concern. For SmartOS it would be a major blow if Joyent were to pull all ressources. They have some of the brightest engineers I know working on it and I have learned a lot from them by just using the system and hanging out on the irc channel in freenode. Without them the speed of development would definitly take a hit.

On the other hand they have been - and still are - very good at building a community around it. There are multiple people and organisations building their own SmartOS images/derivates ([1], [2]). Pull-requests on github come in from a diverse enough group that I think it would survive even without joyent.

For OmniOS I don't have enough insight to make that judgement. They have a very clear and detailed release plan and recently hired some good people just to work on OmniOS. These things definitly add some confidence but of course is not a guarantee forever. But if that would be needed one can always buy support from them.

this is indeed the biggest reason. They have a "hipster"-branch [1] that is getting some updates but I don't follow that closely. Another reason is that they try to target the "developer desktop" which is not that interesting to me personally and also probably a lot more work (driver wise) than they might have the manpower for...

OmniOS on the other hand is pretty solid and with pkgsrc (default package system on SmartOS and NetBSD) you get nearly 13k packages of open-source software.

My List is also missing a few other commercial players that use and contribute to Illumos:

- Delphix, uses ZFS snapshots to do fancy things with big databases

- Pluribus has "Netvisor OS" that is some SDN Router/Networking appliance [3]

And then there is the long tail of small hobby distributions:

- Tribblix, "Retro with modern features" [4]

- DilOS, which has a focus on Xen and Sparc [5]

and probably more that I forgot and don't know.

It is a very nice community and lots of interesting technology gets developed. Our company migrated nearly all servers from Linux to SmartOS in the last 2 years and we could not be happier.

There is indeed a great and active open source ecosystem of Illumos (ex open-solaris) distributions.

Illumos is the de-facto upstream of open-zfs and has many features not found in oracle solaris. [1]

So it is well worth checking out at least one of those:

- SmartOS, which is a fantastic Cloud-Hypervisor [2]

- OmniOS, a classic server distribution, probably best for what OP is building. [3]

- NexentaStor, a storage appliance - but i have not tried it yet [4]

I can definitely recommend using ZFS on a Illumos system as it has much better integration with things like kstats and fault management architecture that I would miss on any other OS.

rawdog/2.19 from the "Unknown" category is an RSS aggregator [1] that should hopefully get fixed with the mentioned python update...

snw··on DogeOS – Very Smart – Many Zones
In spite of the silly name, it has some fantastic tech from SmartOS (ZFS, Zones + KVM, nice tools to manage all that) and is great to use as a cloud hypervisor. Project-FIFO provides a management portal on top of that, so bundling both in a easy to use system makes a lot of sense.

Getting a GbR (Gesellschaft bürgerlichen Rechts ) setup is also possible at the Bürgeramt and similarly easy.

Also: as mentioned in the interview getting a "Steuerberater" once you have some income is a good thing to do. They can advice you in many financial and basic legal things and do most of the paperwork for you so one can concentrate on actual work ;-)
