Sure, most people working as sysadmins can't code. Then again, most people working as programmers can't code either. People who can really write good code are few and far between. The very best sysadmins are also good coders, and

Keep in mind that ranking is based on quarterly sales, not real market share of phones out there. Regardless, Microsoft assumed 3rd Place in Q1 2013, when the Z10 was launched in Canada Feb. 5th and not in the US until Mar. 26th. The Q10, w

Assuming that the exploit really is unknown, what better security could they have done to prevent it, without severely impacting usability? Compromises will happen sooner or later when running a large number of public facing services. With

Just determine how much the cost per user is, and make sure your business model works for that. Beyond that, I'd say not to worry too much about your total hosting costs as the reality is, it's impossible to predict how much resources you'l

Wow, apparently that last comment really hit a nerve, as several people decided to downvote it, but not a single person actually refuted any of what I said. I was under the impression that downvotes were more to be used against trolling or

But that's the point. Most people don't need anything that well-engineered. Compared to more traditional hosting solutions from quality providers, AWS has terrible uptime and at a much higher cost for the same amount of resources. Two VPS'e

If it took 10 years for it to fall 30% in one month, it would depend on all the activity in between, and where the value ended up relative to the original point at which a bubble was called, in real (inflation adjusted, not nominal) dollars

You can have a bubble without it bursting right away. You just can't confirm that it is a bubble until that happens. So long as when the bubble does burst, prices drop well below the point at which you were calling a bubble, you would be pr

Exactly. DoS Arrest was using BGP anycast for DDoS mitigation long before CloudFlare even existed. We had customers on their service back in 2008. I'm somewhat skeptical of CloudFlare's low-cost approach to DDoS mitigation. Going for volume

That's from GTT/NLayer's perspective, which is just one of many Tier 2 network providers. Tier 1 networks are more likely to see the largest attacks.

I'd definitely say it's the latter. The non-PR version of the blog post is that they buy transit and peer at public exchanges out of many locations. Just like every other CDN. I cannot find a single action mentioned in the entire post of so

Exactly. I often see claims of 5-10%, but I've yet to see any reliable set of benchmarks done with those results. Too often, people are using dd and testing throughput instead of actual IOPS. Even the benchmarks that show 20%+ tend to be sk

When it comes to DoS attacks, bandwidth is a much less meaningful metric than packets/s. 300Gbps could be anywhere from 200,000,000 PPS to 4,687,500,000 PPS. High bandwidth attacks just cause congestion issues, while high packets/s actually

Ingress Filtering is a rather vague concept. The actual application of blocking spoofed traffic is known as unicast reverse path forwarding. http://en.wikipedia.org/wiki/Reverse_path_forwarding http://tools.ietf.org/html/rfc3704

Exactly. Virtualization/Cloud are only good for scaling down, not scaling up. The 20-30% hit to IO, additional latency of SAN vs local storage, management overhead, and added complexity to infrastructure more than negate any potential benef

The problem with this technology is that at a 3.5dB/KM loss, it's only really good for about 10KM. At such short distances, the latency difference would only be about 0.0167ms. Given all the other latencies involved between two end-to-end h

The E5 came out last March, is based on the previous Sandy Bridge architecture, and is hardly new. It was also practically a year late, launching the same time as the Ivy Bridge based E3 v2's. The 55xx series was launched in Q1 2009, and th

tcputils from Debian does precisely that, allowing you to extend a UNIX pipe over a TCP connection. It's not generally available as a package in other distros, but you can easily grab the source from Debian and compile it yourself. Conseque

Firstly, the updating problem is a distribution flaw, not a design flaw. The carriers are to blame for that. Secondly, code-signing is a very restrictive approach and is hardly without tradeoffs. If you're going to use iOS as an example, it

He's not wrong. There's always a tradeoff between security and usability. http://www.schneier.com/blog/archives/2009/08/security_vs_us... The key is finding the right balance.

I'm a bit skeptical of the purported 95% of native IO performance. Especially, as in the mailing list thread, the maintainer claimed that it should already have been 95% on local storage, but that this latest version makes that applicable t

Shouldn't that be "ensure" rather than "insure"? You would expect better English, especially on the integrity guidelines page, from a highly regarded news publication like the New York Times.

Linode appears to have a BGP mix of Level3, NTT, Time Warner, KDDI, and Telia vs DigitalOcean's BGP mix of Level3 and Cogent. Linode hands down has the better network connectivity.

by hhw 14y ago
Has nobody else noticed that the benchmarks use ext3 for Linode and ext4 for DigitalOcean? Not that the SSD's won't outperform hard drives anyway, but that's one extra variable that will skew results.
