Intel makes chips with more than 8 cores.

Granted, it's incredibly expensive (as you point out) and I've only seen them in blade applications. But, they do make them. It's also worth pointing out that on the whole, one intel core gives far superior performance than one AMD core of the same clock speed (see Moreover, Intel's hyperthreading can be of a huge help, if your application profile fits.

Measuring $/core or $/CPU Cycle is not a very accurate way to gauge price/performance.

It seems that SSD accelerators can be hit/miss. If you take a look at for example, some of these products don't seem to do anything - while some seem to actually work.

Like any young industry, it'll probably a while to shake out field until only a few decent contenders remain.

Even if no one uses the same physical media as we do now, and even if no one uses the same file formats, storing an entire PC is likely to solve the problem. You can get a small, inexpensive PC for cheap - a couple hundred dollar atom-based machine should do the trick - and throw a large amount of storage in it. I'm fairly certain that standard power connectors will still be available 30 years from now. VGA connectors may not be, so think about storing a small monitor in there as well (someone else can speak to the chances that a monitor will turn on after 30 years).

Going this route gives you practically unlimited storage for photos, music, text, etc.. with very high chances that it will be recoverable.

Data Storage

Nemilar writes "SSD has many benefits — low power, high IO bandwidth, low latency — yet their adoption has been delayed by high cost, device wear and data organization disruption. Still, SSDs are here to stay and the list of vendors and products is getting bigger every day. Rather than adopt SSD arrays as primary storage, some companies are using SSD as a cache mechanism to improve performance while holding on to their traditional storage arrays."

The problem with PGP/signed-emails is that you're putting the burden on the user. I'm a pretty technical guy, and I don't even want to bother with it. There's no way that the average person it going to take the time to understand and implement PGP.

The proposed solution puts the burden entirely on the system and the providers, so is more likely to be adopted and actually used (and therefore, successful in its end-purpose of stopping phishing attacks).

Public high school STEM classes are nowhere near sufficient as far as preparing students for a university-level STEM courseload is concerned.

Maybe if we made public education more about actually teaching and challenging students, rather than a game to see how you can bend the rules to pass the most students, then the first year of college wouldn't be such a difficult experience.

No other company seems as fitting a home for Palm and its webOS software. It’s worth noting that former Palm CEO Jon Rubinstein, who now holds a vague “product innovation” role at HP’s Personal Services Group, joined Amazon’s board late last year."

Comment: Go mainstream: Ubuntu or RHEL (Score 5, Informative) 382

by Nemilar (#37507948) Attached to: Newb-Friendly Linux Flavor For LAMP Server?

I'd suggest that you go with one of the mainstream/common Linux server distros: either RHEL (for which you can use CentOS, which is essentially the same, minus the RedHat-copyrighted bits) or Ubuntu Server.

Either of these can be configured to use a GUI. I'd actually pick RHEL/CentOS over Ubuntu, and during the install (which is graphical), you can select to install a web+database server along with a Desktop (GUI). The installation is fairly straightforward; the most complex part is arguably the partitioning, although you can use the guided partitioner to just use all free space on the disk. Partitioning isn't something that's linux-centric, although the partition scheme for Linux is perhaps a bit more complex than what'd you would expect coming from a Windows world (dedicated swap device, LVM to virtualize the partitions, etc..). If you use the guided "do it for me" option, you can avoid getting your hands wet with this complexity.

The primary reason I'd suggest going mainstream is that the support will be there. If you choose some OS that no one really uses, you'll be hard-pressed to find distro-centric documentation for it. If you go with Ubuntu or RedHat, you can use Google to get through any obstacles you may find. There are plenty of tutorials available when you google for a simple [do this task] on [this distribution]. For example:

While you could probably use this documentation to complete a task on another distro, it's helpful to have a tutorial for the specific OS you're using; all the commands will be the same, and any dependency problems, etc... will all be accounted for.

Additionally, should you decide that you want to learn more and play around, having something mainstream installed means that your learning experience will be directly relevant to anything you want to do down the line.

As an alternative, you could go with a pre-built phpBB appliance. is a single ISO or VDK that is built on Ubuntu Server and comes pre-configured with phpBB (they have many other applications available as well - highly recommended!). It'll ask you a few questions during the install, and once complete, you'll boot up into a fully-functional Linux server with phpBB already running.

This comment reads as total BS.

Let me get this straight - you're running pre-release Ubuntu on 60 production machines? Where's your boss, I think he needs to have a talk with you (and show you the door). No IT professional would be caught dead doing that. Besides, let's be honest here - most accountants and managers "require" MS Office (or some other Windows-only software), and wouldn't use Ubuntu.

And what the hell are you saying about being built on Debian, which leads to professional and real-world experience, whereas Fedora doesn't have that? Have you ever heard of RHEL?

Parent comment is bunk.

I agree that a good GUI for configuration is necessary in foreign environments. I recently had to setup a redhat cluster, and there was no way I was going to get anywhere (in any reasonable amount of time) reading the specifications and modifying the configuration XML by hand. So having the GUI (primitive though it may be) at hand was a life-saver.

But the every step of the way, when I made a configuration change in the GUI, I looked at the XML to see what it was doing. I did this for more than just curiosity, I did it to learn how the system works. Understanding the configuration files gives you an insight into the software that you simply can't get from a GUI. Speed of configuration aside (I think the author of TFA makes a good point here), the CLI is about learning and understanding.

I have to disagree with you about your main point, though. Admins had better be proficient with their shell of choice. Let's assume it's bash -- find me a sysadmin that doesn't know basic bash (for/while, if/else, variables, various conditionals, etc...), and I'll show you someone who's faking it. You don't have to be a full-on programmer, but these are the building blocks of a sysadmin's bash script, and you need to know them.

There's something missing from this entire debate -- it's things like this that will keep large business away from the cloud. One of the most important assets of a company is its confidential information, and unless a business can be certain that the information it stores on a server will remain private and confidential, there's no chance that they'll use cloud-based services.

This has the potential to drive away a lot of business from cloud services. I don't think it will affect Joe Regular on Facebook, but it might certainly turn MegaCorp Inc., and their millions of dollars, away from using cloud service.

On a related note, this bill has one fatal flaw. If I PGP encrypt my data, and don't ever share my private key, then that data remains private and uncrackable by anyone in the line of communication. So I'm not sure how useful this is for terrorism. In fact, probably not useful at all. It's probably only useful for domestic crime.

OK, so I hear this a lot and I never really understand the problem.

The "unwritten gmail contract" (and it actually applies to most Google products) is this: We will give you a service for free (in this case Gmail), and in return we are going to profile your use of that service to select ads for you. In the case of gmail, they give you however many GB of storage, always-on cloud email, and the best searchable email system I've ever seen. There are other Google examples, from gtalk to Google Docs. The basic principle behind it is the same, most people understand the deal, and I don't see anything wrong with it. There's no such thing as a free lunch, but this is pretty close.

I'm in the 500M to 1G camp, and I'm on Verizon. The only reason my data usage is so high is because Verizon offered to give me the "mobile hotspot" feature free for life (a little app on my phone that acts as a gateway and gives me a wireless access point which then routes out to 3G). I use it literally every day, on the train, to connect my netbook to the internet.

Without the mobile hotspot, I would probably use less than 100M per month. And hey, they gave it to me free!
