  1. Re:i don't get it on AMD Hires Bank To Explore Sale Options · · Score: 1

    Intel makes chips with more than 8 cores.

    10 core Xeon: http://ark.intel.com/products/53580/Intel-Xeon-Processor-E7-8870-30M-Cache-2_40-GHz-6_40-GTs-Intel-QPI

    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 http://www.cpubenchmark.net/high_end_cpus.html). 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.

    Sorry, but this is a terrible idea.

    Why should something like a strep throat examination cost the same per hour as an MRI or chemotherapy?

    All that will do is drastically increase the cost of basic services and make them out of reach of most people, reducing the overall access to basic medical care.

  3. All software is not created equal on Are SSD Accelerators Any Good? · · Score: 3, Informative

    It seems that SSD accelerators can be hit/miss. If you take a look at http://www.theregister.co.uk/2012/07/12/velobit_demartek/ for example, some of these products don't seem to do anything - while some seem to actually work.

  4. Use a tiny PC on Ask Slashdot: Storing Items In a Sealed Chest For 25 Years? · · Score: 1

    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.

  5. Re:We already have email authentication on Big Internet Players Propose DMARC Anti-Phishing Protocol · · Score: 5, Insightful

    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).

  6. High school doesn't prepare you for college on Why Do So Many College Science Majors Drop Out? · · Score: 5, Interesting

    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.

  7. Go mainstream: Ubuntu or RHEL on Newb-Friendly Linux Flavor For LAMP Server? · · Score: 5, Informative

    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:

    http://www.google.com/search?gcx=w&ix=c1&sourceid=chrome&ie=UTF-8&q=install+phpbb+on+rhel
    http://www.google.com/#sclient=psy-ab&hl=en&safe=off&site=&source=hp&q=install+phpbb+on+ubuntu+server

    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. http://www.turnkeylinux.org/phpbb 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.

  10. Re:Well there's another side to that on Take This GUI and Shove It · · Score: 1

    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.

  11. Only applies to the cloud on Obama Wants Broader Internet Wiretap Authority · · Score: 1

    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.

  12. Re:An Advertiser's Fantasy ... on Best Way To Archive Emails For Later Searching? · · Score: 2, Interesting

    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.

  13. Verizon teathering on Average Cellphone Data Usage Is 145.8 MB Per Month · · Score: 2, Informative

    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!

    I get your point (that a kernel module, being low-level, gives you greater access), but I think a malicious browser extension is worse.

    * It's a lot less likely that a user will install a malicious kernel module, as compared to a browser plugin.
    * It's a lot easier for someone with bad intentions, a few hours, and a little coding experience to write a browser plugin, than it is for them to write a kernel module.
    * It's much easier to distribute a plugin, and the install base is much greater.
    * The signal/noise ratio of data you would want to steal is much more attractive for a browser plugin, than it would be inside the kernel.

  15. The entertainment companies go too far sometimes on Google's New Scheme To Avoid Unlicensed Music · · Score: 2, Insightful

    I completely "get it" that the entertainment companies need to protect their copyrighted material. That's their product, and it's how they make money; fair enough that they don't want people exploiting it.

    But here's an example of them going too far: The other day I was watching clips from The West Wing on Youtube. I'm not sure how exactly I got there, but regardless, it was one of my favorite shows back in the day, even though the West Wing franchise never got a dime from me either through product purchases or ads. But after seeing a couple of clips, I was reminded of how much I liked the show, and started to consider purchasing the DVD set -- until I clicked on a clip that had no sound. Then I saw that great "this video contains audio not approved by..." on the top of the screen.

    Needless to say, that killed the viewing experience right there. I think when the entertainment companies revisit the sheer dollars and cents, they might see that it's beneficial to leave a lot of this copyrighted material up there -- it might generate a few sales.

  16. The consumer trend seems to be clear on SSDs vs. Hard Drives In Value Comparison · · Score: 2, Insightful

    I think the consumer trend is pretty clear with respect to SSDs (enterprise-level I think is still uncertain). Consumers like the speed and the battery savings (laptops being incredibly popular now) that SSDs provide, but of course there is no way you are going to get the sheer quantity of storage space that you can get with hard disks.

    Consequently, a lot of companies are marketing "home storage servers." I've seen Lenovo, Acer, Asus, etc... all come out with small 4 or 5 bay boxes, usually running Windows Home Server, all aimed at the mid-range consumer market. It makes complete sense to put the platters in a box, where you can keep network-accessible massive storage, and to put the fast, low-power SSD into your client machine.

    The problem arises when you need to access what's on that home NAS while you're out on the road. While I think many people have the upload bandwidth for streaming music, I don't think that exists for video (at least, not in the United States, or at least not where I live). So sites like hulu, etc.. will remain popular in that regard for the time being.

And I am /not/ talking about battery-backed RAID cache, OS write cache, or anything of that nature; I am speaking specifically of the internal hard disk cache.

    When we figured out what was going on, needless to say we were all a bit shaken. But the lesson is learned: your storage needs to have a battery backup system.

  18. Customer Support: not malice, it's bureaucracy on Customers Question Tech Industry's Takeover Spree · · Score: 4, Interesting

    This past week I had two very interesting customer service experiences -- interesting because of just how different they were.

    I spent probably 5 to 7 hours on the phone with HP technical support last week, trying to get them to assist me with a problem we were having with a pair of ProLiant servers. I was shuffled around to multiple departments (and, judging by the various accents, I would say I was probably shuffled to multiple continents as well), each one telling me that the next guy was the right guy to talk to about our issue (which of course he wasn't). This was for a fairly simple question about the functionality of one of their server administration tools, that no one seemed equipped to answer.

    Conversely, we also had a hard disk in a ProLiant server go bad. With the serial and part numbers in hand, I was able to get a replacement shipped within 10 minutes.

    The two completely different experiences I had suggests to me that when companies get large, they get very good at handling the common support problems, like bad hard disks. They develop procedures that save both the company and the customer lots of time, and are relatively painless. But what's lost is the ability to handle the out-of-the-ordinary service needs that customers have; the company is just too big, and the support guy (let's be frank, in some call center in India*) just doesn't have the resources or the knowledge to handle the problem. This leads to a frustrating experience -- whereas in a small company, these things tend to be handled quickly, because the support guy can escalate easily.

    *HP doesn't even try to hide that their support is outsourced to India. If you log-on to their professional support, you can tell right away by the names.

    I would imagine that until now, Foxconn's bean-counters had done the math and figured out that it was cheaper to simply build a factory in China and use cheap labor to make their products. But now that their labor is causing PR problems, demanding raises, and killing themselves for insurance payouts, the bean-counters redid the math and figured out hey, if we keep this up, it would be cheaper just to move to Taiwan and have robots do most of the work. So that's what makes sense, and that's what they'll do.

    I'm not talking to the ethics of the matter, just the fundamentals of the situation, which is that whichever course of action is best for profits is the one that will be taken.

  25. What's the correct form factor for this niche? on Hands-On With Dell's Streak Android Device · · Score: 4, Insightful

    I've seen a few devices of this size (the Archos 7 comes to mind; and I've seen them on the internet, not in person, mind you) and I think it's interesting to watch the industry try to figure out the correct form factor for this new niche that is emerging. Obviously it is going to be something larger than a cellphone and smaller than a laptop -- but what, exactly?

    This Dell Streak, I think, is the exact wrong size. It's quite a bit larger than a phone, and it doesn't look like something that you want to carry around all day in your pant pocket. One of the reason cellphones have become so popular is because they are so small (and light-weight). Remember that for several years, the major thing about cellphones is that they were getting smaller and smaller? Compare a phone from, say, 2000, with a phone from today. Why would anyone want to reverse direction on that? It's too large for a phone.

    On the opposite end, it looks too small to do any actual work. A netbook-sized screen is good for emails and browsing, but it's not very useful for doing serious business. And this thing is much smaller than a netbook. I don't think that's the aim, of course -- I think it's more aimed to the niche that the iPod targets; gaming, "always-on" style internet access, etc.. But I have to wonder if the device is too small for these things, as well. I think it might very well be.

    But the overwhelming thing we seem to be seeing is that there are plethora of devices being released, each being in some significant way different from the next; companies are trying to find out what consumers want in a device like this. Maybe Apple has proven it with the iPad, given its popularity; they did that with the iPod, and now the market is full of MP3 players which are essentially iPod clones. But remember when MP3 players were first coming to market, there were many different form factors, many different storage devices (Sony had that thing with the mini CDs, for example), until it became clear what consumers want. The same thing should/will happen here; and I believe it's quite possible it's already happened with the iPad, and anyone making anything substantially different will wind up falling behind.
