  • How can I make xmlpp::DomParser less verbose on errors?

    - by Beau Simensen
    How can I make xmlpp::DomParser be less verbose on errors? Right now, if parsing fails, I get a bunch of text printed to my console and I'd just as soon have that not be visible. Entity: line 1: parser error : Opening and ending tag mismatch: feed line 1 and fed <feed><entry id='5' /></fed> I don't see a lot of options for xmlpp::DomParser but I have to believe this is something that can be disabled/tweaked.

  • How do you check to see if a variable has changed every second or less in objective c?

    - by James
    I am using an if statement to check the value of a BOOLEAN when i click on a button. When the button is clicked if the value is false i want to display a UIActivityIndicator and if the value is true i want to push the new view. I can do this fine but i want the view to change automatically when the BOOLEAN Becomes true if the user has already clicked the button. So my question is how do you check to see if a value has changed everysecond or less?

  • is there a less bloated way to test constraints in grails?

    - by egervari
    Is there a less bloated way to test constraints? It seems to me that this is too much code to test constraints. class BlogPostTests extends GrailsUnitTestCase { protected void setUp() { super.setUp() mockDomain BlogPost } void testConstraints() { BlogPost blogPost = new BlogPost(title: "", text: "") assertFalse blogPost.validate() assertEquals 2, blogPost.errors.getErrorCount() assertEquals "blank", blogPost.errors.getFieldError("title").getCode() assertEquals "blank", blogPost.errors.getFieldError("text").getCode() blogPost = new BlogPost(title: "title", text: ObjectMother.bigText(2001)) assertFalse blogPost.validate() assertEquals 1, blogPost.errors.getErrorCount() assertEquals "maxSize.exceeded", blogPost.errors.getFieldError("text").getCode() } }

  • MD3200 - 3 to 4x less throughput than MD1220. Am I missing something here?

    - by Igor Polishchuk
    I have two R710 servers with similar configuration. One in my office has MD1220 attached. Another one in the datacenter of my hosting services vendor has MD3200. I'm getting significantly worse throughput from MD3200 at my vendors setup. I'm mostly interested in sequential writes, and I'm getting these results in bonnie++ and dd tests: Seq. writes on MD1220 in my office: 1.1 GB/s - bonnie++, 1.3GB/s - dd Seq. writes on MD3200 at my vendor's: 240MB/s - bonnie++, 310MB/s - dd Unfortunately, I could not test the exactly the same configurations, but the two I have should be comparable. If anything, my good performing environment is cheaper than the bad performing. I expect at least similar throughput from these two setups. My vendor cannot really help me. Hopefully, somebody more familiar with the DAS performance can look at it and tell if I'm missing something here and my expectations are too high. To summarize, the question here is it reasonable to expect about 100MB/s of sequential write throughput per each couple of drives in RAID10 on MD3200? Is there any trick to enable such performance in MD3200 with dual controller as opposed to simple MD1220 with a single H800 adapter? More details about the configurations: A good one in my office: Dell R710 2CPU X5650 @ 2.67GHz 12 cores 96GB DDR3, OS: RHEL 5.5, kernel 2.6.18-194.26.1.el5 x86_64 20x300GB 2.5" SAS 10K in a single RAID10 1MB chunk size on MD1220 + Dell H800 I/O controller with 1GB cache in the host Not so good one at my vendor's: Dell R710 2CPU L5520 @ 2.27GHz 8 cores 144GB DDR3, OS: RHEL 5.5, kernel 2.6.18-194.11.4.el5 x86_64 20x146GB 2.5" SAS 15K in a single RAID10 512KB chunk size, Dell MD3200, 2 I/O controllers in array with 1GB cache each Additional information. I've also ran the same tests on the same vendor's host, but the storage was: two raids of 14x146GB 15K RPM drives RAID 10, striped together on the OS level on MD3000+MD1000. The performance was about 25% worse than on MD3200 despite having more drives. When I ran similar tests on the internal storage of my vendor's host (2x146GB 15K RPM drives RAID1, Perc 6i) I've got about 128MB/s seq. writes. Just two internal drives gave me about a half of 20 drives' throughput on MD3200. The random I/O performance of the MD3200 setup is ok, it gives me at least 1300 IOPS. I'm mostly have problems with sequentioal I/O throughput. Thank you for looking into it. Regards Igor

  • Is Firefox less vulnerable to exploit when running NoScript?

    - by PP
    The article titled "iPhone, IE, Firefox, Safari get stomped at hacker contest" at The Register website discusses that Firefox can be exploited. I wonder if NoScript protects against the kind of exploits written about; or whether the browser can be exploited regardless of having the extension loaded. Any opinions? Might make this a community wiki given that it's not simple problem/solution post.

  • VPN - What is the complexity involved setting one up across less than a dozen machines?

    - by lucius
    Hello, I have never set up and configured a VPN. I was wondering what it takes to set one up across windows server 2008 servers. What is the complexity involved? How complicated is it to configure? Do I need to set up a Domain controller as a pre-requisite? I am asking because it appears SQL Server 2008 merge replication can only be set up over the internet using VPN and I am trying to gauge what I am up against. Thanks a lot.

  • Access 2007: How can I make this EXPRESSION less complex?

    - by Mike
    Access is telling me that my new expression is to complex. It used to work when we had 10 service levels, but now we have 19! Great! My expression is checking the COST of our services in the [PriceCharged] field and then assigning the appropriate HOURS [Servicelevel] when I perform a calculation to work out how much REVENUE each colleague has made when working for a client. The [EstimatedTime] field stores the actual hours each colleague has worked. [EstimatedTime]/[ServiceLevel]*[PriceCharged] Great. Below is the breakdown of my COST to HOURS expression. I've put them on different lines to make it easier to read - please do not be put off by the length of this post, it's all the same info in the end. Many thanks,Mike ServiceLevel: IIf([pricecharged]=100(COST),6(HOURS), IIf([pricecharged]=200 Or [pricecharged]=210,12.5, IIf([pricecharged]=300,19, IIf([pricecharged]=400 Or [pricecharged]=410,25, IIf([pricecharged]=500,31, IIf([pricecharged]=600,37.5, IIf([pricecharged]=700,43, IIf([pricecharged]=800 Or [pricecharged]=810,50, IIf([pricecharged]=900,56, IIf([pricecharged]=1000,62.5, IIf([pricecharged]=1100,69, IIf([pricecharged]=1200 Or [pricecharged]=1210,75, IIf([pricecharged]=1300 Or [pricecharged]=1310,100, IIf([pricecharged]=1400,125, IIf([pricecharged]=1500,150, IIf([pricecharged]=1600,175, IIf([pricecharged]=1700,200, IIf([pricecharged]=1800,225, IIf([pricecharged]=1900,250,0)))))))))))))))))))

  • What are the best code-less website design sites available?

    - by Ken Pespisa
    I'm looking for an alternative to www.squarespace.com. Squarespace is great, but leans slightly toward the social networking industry. I'm looking for a simple way to build Web sites for small businesses. The criteria is the following: Requires no programming knowledge. No software to download - all design and maintenance can be done via browser Has a good selection of templates and layouts Essentially I'm looking for the features within Typepad.com or WordPress.com, but instead of focusing around a blog it would help build a more traditional Web site.

  • How to create a password-less service account in AD?

    - by Andrew White
    Is it possible to create domain accounts that can only be accessed via a domain administrator or similar access? The goal is to create domain users that have certain network access based on their task but these users are only meant for automated jobs. As such, they don't need passwords and a domain admin can always do a run-as to drop down to the correct user to run the job. No password means no chance of someone guessing it or it being written down or lost. This may belong on SuperUser ServerFault but I am going to try here first since it's on the fuzzy border to me. I am also open to constructive alternatives.

  • Wireless technology - which is better: more single radio APs or less dual radio APs?

    - by gert_78
    We are currently talking to vendors of wireless solutions for a wireless deployment in a university campus with some 5000 students. One vendor is offering us a Cisco solution with a WLC 5508 controller and 69 2x2 MIMO Dual-band/Dual radio APs (Aironet AP 1042 model) The other vendor is offering us an Aruba solution with a 3600 controller and 96 2x2 MIMO dual band BUT single radio APs (Aruba AP93) Both vendors are charging 82.000 US$ (support, 3y service contracts, switches and additional required options all included of course) The Aruba vendor is trying to convince me that 96 single radio APs will give us more connection/users/capacity then the 69 dual radio APs. I have my doubts about that and since it is my core competence-domain I wanted to ask here the opinion of people that have a more profound knowledge and experience in this area. When you talk to vendors it's often hard to get objective information. So try to answer only if you are sure and please mention it if you are affiliated with one of the vendors. I appreciate all useful help and want to thank you in advance for the effort!

  • How can I calculate the sum of all positive integers less than n?

    - by Adrian Godong
    I have the following function: f(n) = f(n - 1) + (n - 1) f(0) = 0 n >= 0 I have n declared on column A, and need the result of f(n) on column B. I'm trying to find the Excel formula equivalent for this function. Sample Result: A | B --+-- 0 | 0 or: A | B --+-- 1 | 0 or: A | B --+-- 4 | 6 but never: A | B --+-- 0 | 0 1 | 0 2 | 1 ... The biggest problem is, I can't simulate the value of f(n - 1). So referencing the previous row like the above example is invalid. I'm almost sure the answer is trivial, I just can't find it.

  • Can / how to install openSUSE as a GUI-less home server with only wifi?

    - by Dougal
    Hello there, I'm following an article to set up openSUSE as a commandline server (http://www.howtoforge.com/perfect-server-opensuse-11.1). It seems to only work for wired internet connections. Is there any way to install openSUSE as a commandline server in my home network but using a wifi internet connection? Preferably from the get-go and not simply installing with LAN cable internet and then installing some wifi things later. Or, perhaps, to rephrase the question "How can I get the openSUSE install / post-install procedure to recognize my wifi internet connection?" Kind regards, Dougal
