This is not old code. This is the kernel of ESXi 5.5 (Their current product) and its highly likely that ESXi 6.0 has the same problem. This is not old code, it is the heart of their product offerings.

I consider google with android to be a similar position to the linux kernel on my servers. I don't expect any of the kernel team to produce a patch for my 2.6.18 kernel I am running on a RHEL 5 system, I expect Red Hat to do that. Why

Well, thats been tried and rejected by the user base. If you harden too much it becomes a real PITA to do anything productive (SELinux running in strict mode). RHEL aims to be secure, while also remaining fairly compatible with previous ver

While I strongly agree in net-neutrality principles, there is the case that in these scenarios the data may not have the same costs to provide, and some may be cheap enough that it doesn't make sense to charge from. In Australia at lea

I am assuming by encryption in motion you are talking about using SSL tunnels to transfer the data. I can't see much in the way of details so I figured you might be able to help - How do you ensure consistency of the disk for the snaps

Python 2 is already on all my systems (OS X, Centos 5/6/7). Python 3 needs to be deployed. Since I write a lot of sub 1000 line scripts for system admin tasks, it tends to not be worth forcing a Python 3 dependency just to make so

4G speeds is pretty much the state of the art in production ready systems. While there is a lot of speed available on LTE, once it is shared across a reasonable number of people the performance drops. This is why bandwidth caps are so tight

I have to say I love Red Delicious apples when they are fresh. They are the worst for shelf life so you need to be careful, but I will take one at its freshest over any other variety I have tasted.

RAID only works when the RAID controller doesn't screw up, or critical metadata doesn't get wiped. If the raid controller starts being the problem your data goes with it. Problem can also happen if your hypervisors filesystem &#x2

This is kind of already available for VDI if your willing to accept the overhead of multiple OS instance. Nvidia GRID and similar GPU / Compute boards can handle multiple simultaneous users. The problem is COST. These are designed for

Isn't the first GB of your account traffic free with AWS vs DO giving you 1 TB per droplet? While 1 EC2 instance may not use more then 1 GB (which is a very low quota unless your CDNing everything), if you have a couple of instances yo

Why not have engineers in different time zones? 12:30am on EST is 3:30pm AEST (Australian Eastern Standard Time) and 7:30am in London. That way you have skilled people awake all hours should a major issue develop. These people can fix the p

I've really only seen 2 core approaches to this: 1.) Free Access to everything. You trust everyone and hope it works out right. This is the simplest solution, but offers nothing to prevent someone violating that trust. 2.) Lock product

This has since been fixed. Red Hat appeared to have screwed up and nuked the name server configuration when they took ownership of the centos.org domain. Nice 4 hour+ outage.

What really surprises me is that by this graph it really seems APNIC is better rationing its allocation the most of the other RIRs with it projecting still having small numbers of IPs available for crossover after 2020. Part of this is that

I may be mistaken, but aren't the larger EC2 machines priced fairly linearly with the improved resources? i.e. a machine with 2x the resources typically costs 2x as much? If this is the case then can someone let me know the use case? I

I would also add that in most DCs your never going to have the power capacity to have racks filled with 1RU servers, so 2RU servers are typically not much more expensive to Rack then their slimmer brethren.

We did this with APNIC (being based in Australia), and we were able to justify a /24 on a single server without multi-homing. I don't think they allocate less then a /24 so if you have cause for 1 you get the whole /24.

I would argue that dedicated servers are MORE resilient then any cloud provider. And it really isn't that hard, 2 enterprise class servers + VMWare or similar and you have a HA cluster. The hardware support is largely done by the hardw

Couple of bits of advice to anyone doing this: Firstly get your own IPs from your local RIR. Have your co-lo provider publish your routes, but they will be YOUR IPs. if you co-lo provider sucks, you can move and keep your IP space. (This is

Cost is the big one, If you can manage your own metal you can save a LOT. 50K AUD of gear would cost us ~ 10x PER YEAR for the same VM sizes (many are 32gb of Ram, 8+ vCPU, reasonable IOPS). IP addresses is another. AWS gives you 5 before y

Back at the RHEL6 launch (working for Red Hat Support) scuttlebutt around Red Hat was that they weren't confident they had the resources to provide full support for all clients for XFS. At that time it was offered as an add-on for a su
