Probably stupid question, what is RHEL's developer subscription? Is it free RHEL? Why not CentOS then?

Thanks, will look into it. My google-fu failed me for some reason. (I blame duckduckgo this time)

If you virtualise it, the one license covers two vms.

This actually is really useful for a few courses I help with.

I think you've sort of stumbled upon the answer there. Whenever I think about evangelical C programmers I think of the linux devs, and their scoffing at C++ programmers for using a bastardised version of their beloved C.

And Eden's right, C is everywhere. It's why we still teach it at universities. As soon as you want to play with hardware you need to stick with C as the wealth of tools and support is unmatched, purely because of the legacy of it all. It's also useful to know because many modern languages are still implemented in it, such as Python. You can't understand a lot of the parts of Python and memory management without knowing how things are done in C.

Have you ever got boards manufactured from china pcb manufacturer?

Which do you guys think is faster? If a program had like normal algorithms/data structures that are not too fast but not a bad big O but had perfect multi threading. Then you have another program that uses the fastest algorithms but only uses a single thread.

depends on hardware and scale of workload

Hey guys I want to contact IBM recruitment because I want to talk about a coop 2018. Would any of you know how I could contact them?

This?

https://www.ibm.com/contact/us/en/?lnk=flg-cont-usen?lnk=flg

Under e-mail support it says:

General 'non-technical' questions, concerns, or Web-site feedback.

For technical questions, please see our "Support directories" section.

Wait... I am unsure. I was on the recruitment website, clicked the contact link at the bottom and that link brings you to the main IBM website and that is the link I linked....

thanks, I sent them a message maby they can redirect me to recruitment.

Are we talking infinite cores here? In general, this tends to actually Dependant upon the algorithm. Also, because data must come from a common source and all be merged, O(n) is the lower bound on any constructible machine. So things like binary search would be better on a single core, but TSP would do better over infinite cores.

I'm surprised the symantic SSL/TLS chrome certificate revocation hasn't been bigger news, considering the size of their reach.

Anyone else started to see emailing coming in offering free replacements for symantic certificates? I've had one from namecheap.

I havent seen that, what does a SSL/TLS certificate do and how does it work?

Certificates are used to encrypt web connections (among other things) so, https.
symantec are a giant money pit in this.

Google have found them to be mis-issuing certificates over a period of years (not necessarily maliciously), and have decided to depreciate and remove trust to existing symantec certificates

That means over a period of time certificates before a certain date will become invalid and the https connections using them will be untrusted. they also want to revoke the extended validation immediately.
