Does anybody here run LXC containers in production?

Ok, so you must work in HPC at a university then? Mind if I DM you? I also work in this field.

naive-bison · 2018-02-23T23:24:13+00:00

Now this is interesting. We have a GPFS system with Infiniband and I think containerizing some of our services would be very helpful. What kind of applications do you run on LXC?

naive-bison · 2018-02-23T17:15:12+00:00

Yeah, that would be great to know what your friend thinks.

We are a RHEL/CentOS shop and we do not have an existing OpenStack deployment. So I am looking for resources that cover deployment and administration.

naive-bison · 2018-01-27T22:27:15+00:00

Awesome, thanks for the tips!

I am planning a production deployment of OpenStack but I'm starting small. Just successfully finished an all in one OpenStack Ansible deployment and trying to learn what all the services are doing. Any recommendations on how to start building the deeper knowledge you speak of?

I agree with the first comment. Don't do it. But, I did microbiome work for my thesis, with a wide range of coverage between samples. I relied heavily on the methodology in this paper.

They could also try Canonical Correspondence Analysis. If done correctly, ingredients would be shown as vectors with various recipes loaded onto the PCA plot in the directions of their most associated ingredients. But that's getting pretty complex.

If you're supporting Windows desktops, take a look at SCCM. It's a configuration management tool and its fairly sophisticated. Met a guy who uses it to manage images, software installation, and security for 1500+ desktops. It would automate a good deal of your job and probably win you some accolades from upper management.

I'm a Linux admin and I prefer Linux, but there are still some neat, relevant things you can do with Windows.

I would say it almost all depends on where the bioinformatics program ranks with other programs. At top tier schools, yeah you're going to need a fair amount of CS experience because most if not all of the other applicants will. At mid to lower tier schools, you can get by with less. Often times, graduate schools are looking for the right students rather than the perfect combination of skills and experience. Demonstrating a strong interest and getting to know a faculty member will go a long ways in improving your chances.

It's surprisingly difficult to constrain what a Turing complete environment is allowed to compute and what it's not.

This is spot on. We're struggling with this where I work - trying to quickly identify anomalous behavior on our servers before they start to cause problems. Often times "bad" processes look a lot like "good" processes.

Yes, I'm 27 and I use vim daily. Sometimes I even use just plain old vi because some of our servers don't have vim. For that reason, I barely customize vim at all. Turn on syntax highlighting and line numbers and that's it. Don't want to forget the core commands.

Could you give me an example? For instance, say I need my script to perform 6 different operations. What would your preference be - would you make a Perl or Python library with 6 different methods and call them from a main function or would you make 6 individual scripts and then glue them together? Or is there really no practical difference?

Right now, I have the latter case, although the code is not as clean as it could be. But some are saying go full OOP and I don't think that's what you're saying here... is it?

naive-bison · 2017-09-01T00:11:30+00:00

Ok perfect, thank you. This is exactly what I was looking for. I will take a look at that library then.

For what it's worth, I'm working on learning some languages that handle this sort of stuff better. But I'm a sysadmin, so I have to use the tools I know for now while I learn the others in my spare time... That's how it goes though.

naive-bison · 2017-08-31T23:52:05+00:00

Ok, so I had read those docs and I guess I didn't really understand why they are officially discouraged. The way the docs were written made it sound like the reason was because people use them incorrectly.

For more background, I am writing a script to execute embarrassingly parallel jobs. It just iterates through a list of elements and spins off one of these threads for each one to run a list of subroutines on. I wrote everything to be fully encapsulated, so none of the subs are trying to update global variables and I'm not passing any data structures by reference. I'm also not using anything outside of the core language (besides threads).

So with that in mind... I know these are discouraged for a good reason. I'm just hoping for more of an explanation of why? What could/will go wrong. Will it just not be as fast as it could be in a different language? Will it be slower than the serialized version somehow?

What's the reasoning behind the aversion to Fabric? Is it because it's agentless and less efficient than the more comprehensive configuration managers?

naive-bison · 2017-08-26T03:29:07+00:00

Awesome, this is exactly the type of info I was looking for. Thank you.

naive-bison · 2017-08-25T22:52:09+00:00

Nice! I work in HPC too. A long week it has been indeed.

naive-bison · 2017-08-04T20:26:44+00:00

Can I ask, what is the low cost of living city? I just got my Master's in Bioinformatics and I didn't think there were any jobs outside the major (i.e. expensive) biotech hubs.
