  • would it be bad to put <span> tags within the <head>, for grouping meta data in schema.org format?

    - by hdavis84
    Alright, I'm currently practicing schema.org microdata, and trying to find the best route for every site I build. I have found that i can piggyback itemprops on open graph meta tags. I would like to piggyback more itemprops on opengraph meta tags. However, schema.org requires you to change itemtypes to define all aspects of a "thing". Say I'm defining a LocalBusiness. Open graph has street address, locality, and region i'd like to piggyback on. I'd have to do something like: <html lang="en" itemscope itemtype="http://schema.org/LocalBusiness"> <head> ... <meta itemprop="name" content="Business Name" /> <meta property="og:url" itemprop="url" content="http://example.com" /> <meta property="og:image" itemprop="image" content="http://example.com/logo.png" /> <span itemprop="address" itemscope itemtype="http://schema.org/PostalAddress"> <meta property="og:street-address" itemprop="streetAddress" content="1234 Amazing Rd." /> <meta property="og:locality" itemprop="addressLocality" content="Greenfield" /> <meta property="og:region" itemprop="addressRegion" content="IN" /> </span> </head> Although there's more that can be added in, this is enough of an example to show what I'm trying to achieve. I've searched the web to see if it is an issue to use spans in the head or not, because I don't want invalid markup. I know I can mark up the address information in the body of the pages, but the route above would be more efficient. Does anyone have an answer for this?

  • How can I locate the frames of a spritesheet PNG based on this PLIST data?

    - by kitsune
    Someone asked me to reskin a certain game. Now he only sent me the whole sprite PNG and PLIST files of the sprites. He instructed me to rename each sprite with the same name corresponding to each original sprite. The problem is, he gave me the whole sprite sheet instead of each individual sprite and the PLIST. Now yes, I can read the PNG filenames from the PLIST, but I cannot rename the reskin sprites I did because I'm not sure which sprite is boy_gun_3_3.png; there are multiple guns, I don't know which is which. Is there a way to extract individual accurately named individual PNG files from the single sprite sheet using the PLIST?

  • How can I write data to a file that users can't easily edit?

    - by ThePlan
    While working on game saving and loading I figured I could just write all the variable values to a file and then load that file from it's default location anytime. However from the very beginning it sounded like an odd job. I know about serialization and boost, but that seems so complicated, I figured I'd keep it simple, but I've ran across this huge issue: No matter what file I can write with C++, the user can get their hands on it, they can edit their position, they can remove a boss, or add new weapons for themselves. My question here is: How can I create a file in C++ which cannot be editted or openned with a text editor such as Notepad (I'm not trying to make a file which is impossible to open, but a file which will give the user a headache if he tries to edit it through usual methods.)

  • Are We Losing a Standard (Edition) Data Recovery Technology?

    - by AllenMWhite
    One of the coolest technologies Microsoft released with SQL Server 2005 was Database Mirroring, which provided the ability to have a failover copy of a database on another SQL Server instance, and have the ability to automatically failover to that copy should a problem occur with the primary database. What was even cooler was that this new technology was available on Standard Edition! Mom and Pop shops could afford to implement a high availability solution without paying an extra tens of thousands...(read more)

  • Trying to grok Linux quotas, where is the data stored?

    - by CarpeNoctem
    So all the tutorials and documentation for the Linux quota system has left me confused. For each filesystem with quotas enabled/on where is the actual quota information stored? Is it filesystem metadata or is it in a file? Say user foo creates a new file on /home. How does the kernel determine whether user foo is below their hard limit? Does the kernel have to tally up quota information on that filesystem each time or is it in the superblock or somewhere else? As far as I understand, the kernel consults the aquota.user file for the actual rules, but where is the current quota usage data stored? Can this be viewed with any tools outside repquota and the like? TIA!! Update: Thanks for the help. I had already read that mini-HOWTO. I am pretty clear on the usage of the user space tools. What I was unclear on is whether the usage data was ALSO in the file that stored per-user limits and you answered this with a yes. From what I can tell, rc.sysinit runs quotacheck and quotaon on startup. The quotacheck program analyzes the filesystem, updates the aquota.* files. It then makes use of quota.h and the quotactl() syscall to inform the kernel of quota info. From this point forward the kernel hashes that information and increments/decrements quota stats as changes occur. Upon shutdown, the init.d/halt script runs the quotaoff command RIGHT before the filesystems are unmounted. The quotaoff command does not appear to update the aquota.* files with the information the kernel has in memory. I say this because the {a,c,m}times for the aquota.user file are only updated upon a reboot of the system or by manual running the quotacheck command. It appears - as far as I can tell - that the kernel just drops it's up-to-date usage data on the floor at shutdown. This information is never used to update the aquota.* files. They are updated during startup by quotacheck(rc.sysinit). Seems silly to me since that updated info had already been collected by the kernel. So...in conclusion I am still not entirely clear on the methods. ;)

  • How can I retrieve data from a Western Digital Passport External Disk which is not getting recognized but getting shown as healthy in Device manager

    - by Rabimba Karanjai
    When I plug in this external harddisk It is not getting shown in the My Computer. But it gets shown perfectly well in the Device Manager When I go into the Computer Administrative panel and into the disk manager it asks me to initialize the disk Now when I try to initialize it, regardless of the method I try it shows me an error "Incorrect Function" As you can see windows tells me it is working properly. Is there anyway I can retrieve data from this?/access it? I have googled and it seems to be a frequent problem with WD drives. Anyone has any solutions on how I can get the data back?

  • How do I add a counter for process data in perfmon.exe for a process that isn't currently running?

    - by Jason Jones
    I would like to perform an ad hoc capture of data using perfmon.exe for a process that runs during the night. I know the name of the executable--lets call it Foo.exe. If the process were currently running, I would go to the Add Counters dialog in perfmon, switch to the Process object, and select the Foo instance from the list. However, it's not currently running. Is it possible to set up perfmon so that it will capture process data for this process when it starts, and if so, how would I configure it to do so?

  • Changing Word mail merge data source locations in bulk?

    - by Daft Viking
    I've just moved a number of Word mail merge files, and a number of Excel spreadsheets that are the data sources for the mail merges, from a Windows XP computer to a Windows 7 computer, and now all the paths for the merge sources are incorrect (used to be c:\documents and settings\user\my documents.... now c:\users\documents....). While I can correct the path of the data source in each file individually, I was hoping that there would be some way of updating the files in bulk, as there are a relatively large number of them. Word 2007 is what is being used, but the documents are all in the previous DOC format (not DOCX).

  • How to define implementation details?

    - by woni
    In our project, an assembly combines logic for the IoC-Container, the project internals and the communication layer. The current version evolved to have only internal classes in addin assemblies. My main problem with this approach is, that the entry point is only available over the IoC-Container. It is not possible to use anything else than reflection to initialize the assembly. Everything behind the IoC-Interface is defined as implementation detail and therefore not intended for usages outside. It is well known that you should not test implementation detail (such as private and internal methods), because they should be tested through the public interface. It is also well known, that your tests should not use the IoC-Container to setup the SUTs, because that would result in too much dependencies. So we are using the InternalsVisibleTo-Attribute to make internals visible to our test assemblies and test the so called implementation details. I recognized that one problem could be the mixup between different concerns in that assembly, changing this would make this discussion useless, because classes have to be defined public. Ignoring my concerns with this, isn't the need to test a class enough reason to make it public, the usages of InternalsVisibleTo seems unintended, and a little bit "hacky". The approach to test only against the publicly available IoC-Container is too costly and would result in integration style tests. The pros of using internals are, that the usages are well known and do not have to be implemented like a public method would have to be (documentation, completeness, versioning,...). Is there a solution, to not test against internals, but keep their advantages over public classes, or do we have to redefine what an implementation detail is.

  • How to avoid oscillation by async event based systems?

    - by inf3rno
    Imagine a system where there are data sources which need to be kept in sync. A simple example is model - view data binding by MVC. Now I intend to describe these kind of systems with data sources and hubs. Data sources are publishing and subscribing for events and hubs are relaying events to data sources. By handling an event a data source will change it state described in the event. By publishing an event the data source puts its current state to the event, so other data sources can use that information to change their state accordingly. The only problem with this system, that events can be reflected from the hub or from the other data sources, and that can put the system into an infinite oscillation (by async or infinite loop by sync). For example A -- data source B -- data source H -- hub A -> H -> A -- reflection from the hub A -> H -> B -> H -> A -- reflection from another data source By sync it is relatively easy to solve this issue. You can compare the current state with the event, and if they are equal, you don't change the state and raise the same event again. By async I could not find a solution yet. The state comparison does not work by async event handling because there is eventual consistency, and new events can be published in an inconsistent state causing the same oscillation. For example: A(*->x) -> H -> B(y->x) -- can go parallel with B(*->y) -> H -> A(x->y) -- so first A changes to x state while B changes to y state -- then B changes to x state while A changes to y state -- and so on for eternity... What do you think is there an algorithm to solve this problem? If there is a solution, is it possible to extend it to prevent oscillation caused by multiple hubs, multiple different events, etc... ? update: I don't think I can make this work without a lot of effort. I think this problem is just the same as we have by syncing multiple databases in a distributed system. So I think what I really need is constraints if I want to prevent this problem in an automatic way. What constraints do you suggest?

  • Why is a software development life-cycle so inefficient?

    - by user87166
    Currently the software development lifecycle followed in the IT company I work at is: The "Business" works with a solution manager to build a Business Requirement document The solution manager works with the Program manager to build a Functional Spec The PM works with the engineering lead to develop a release plan and with the engineering team to develop technical specifications If there are any clarifications required, developers contact the PM who contacts the solution manager who contacts the business and all the way back introducing a latency of nearly 24 hours and massive email chains for any clarifications By the time the tech spec is made, nearly 1 month has passed in back and forth Now, 2 weeks go to development while the test writes test cases Code is dropped formally to test, test starts raising bugs. Even if there is 1 root cause for 10 different issues, and its an easily fixed one, developers are not allowed to give fresh code to test for the next 1 week. After 2-3 such drops to test the code is given to the ops team as a "golden drop" ( 2 months passed from the beginning) Ops team will now deploy the code in a staging environment. If it runs stable for a week, it will be promoted to UAT and after 2 weeks of that it will be promoted to prod. If there are any bugs found here, well, applying for a visa requires less paperwork This entire process is followed even if a single SSRS report is to be released. How do other companies process such requirements? I'm wondering why, the business cannot just drop the requirements to developers, developers build and deploy to UAT themselves, expose it to the business who raise functional bugs and after fixing those promote to prod. (even for more complex stuff)

  • Correct permissions for /var/www and wordpress

    - by dpbklyn
    Hello and thank you in advance! I am relatively new to ubuntu, so please excuse the newbie-ness of this question... I have set up a LAMP server (ubuntu server 11.10) and I have access via SSH and to the "it works" page from a web browser from inside my network (via ip address) and from outside using dyndns. I have a couple of projects in development with some outside developers and I want to use this server as a development server for testing and for client approvals. We have some Wordpress projects that sit in subdirectories in /var/www/wordpress1 /var/www/wordpress2, etc. I cannot access these sub directories from a browser in order to set up WP--or (I assume) to see the content on a browser. I get a 403 Forbidden error on my browser. I assume that this is a permissions problem. Can you please tell me the proper settings for the permissions to: 1) Allow the developers and me to read/write. 2) to allow WP set up and do its thing 3) Allow visitors to access the site(s) via the web. I should also mention that the subfolder are actually simlinks to folder on another internal hdd--I don't think this will make a difference, but I thought I should disclose. Since I am a newbie to ubuntu, step-by-step directions are greatly appreciated!

  • What's the correct approach for passing data from several models into a service?

    - by Doug Chamberlain
    I have an AccountModel and a page where the user can upload a file. What I would like to have happen is when the user uploads the file. The PageController does something like the following. this is a quick attempt just written in the question to illustrate my question. public class PageController : Controller { private Service service; public ActionResult Upload(HttpPostedFileBase f){ service.savefile(f,_AccountModel_whatever.currentlyloggedinuser.taxid) } } public class Service { // abunch of validation and error checking to make sure the file is good to store } Wouldn't this approach be in bad practice? Since I'm making my controller dependent on the existence of th AccountModel? This will become a HUGE program over the next few years, and I really want to maximize the quality of the framework now.

  • The good SQL database to process a lot of data?

    - by Dorian
    I have to process like 10-100 millions records. I have to give the data to the client when it's finish. The data is givent as SQL requests to execute in the database. He have a powerful server with MySQL, I think it will be fast enough. The issue is my computer is not as powerful as his server, so I would like to use an other SQL server who is compatible (I export his database and import it in my computer) with MySQL but more powerful. What should I use? Or am I doomed to use MySQL?

  • Is it reasonable to make a RAID-1 array with a ram disk and a physical disk to maximize read performance and protect data?

    - by Petr Pudlák
    In one of the answers on SO (I forgot which one) I've seen a suggestion to make a RAID-1 array composed of a RAM disk and a physical partition. By adding the physical partition with --write-mostly and enabling --write-behind the system should read everything instantly from the RAM disk but still save all data to the physical partition so that the data are preserved and the RAID array can be assembled again after reboot. Is such a setup reasonable? Will it perform any better in some scenario than having just the physical partition and perhaps tweaking the kernel to favor disk cache (swappiness and vfs_cache_pressure)?

  • What are good/fast methods to pull data from a database using JavaScript?

    - by Yatrix
    I'm pretty new to web technologies and I am creating a filter control that will have cascading controls. We are doing a lot of this through JavaScript and are debating the best route to take to the database. HTTPHandlers, WebServices and Ajax are all being considered (or a combination of them). We want to be able to handle a million rows in theory, so it has to be scalable to at that. We are going through JavaScript as our page must not do post-backs, if your'e wondering. I'm asking from an architectural standpoint, but will take any useful information. Links, control suggestions - anything you have, I'll happily listen to.

  • Simple C: atof giving wrong value [migrated]

    - by Doc
    I have a program that reads input from a singe line(string obviously) and organizes it into arrays. The problem I have is that at one point the program reads two different values and returns the first one twice. Initially I thought the program was reading the same value twice but when I tested it turned out that it got the correct one but is inputting the wrong one. for example Input: 2 0.90 0.75 0.7 0.65 sorry to snip it (while(fgets (string[test], sizeof(string[test]),ifp)) pch = strtok_r(NULL, " ", &prog); tem3 = atoi(pch); while (loop<tem3) { pch=strtok_r(NULL," ",&prog); venseatfloat[test][loop][DISCOUNT][OCCUPIED]=(float)atof(pch); printf("%f is discount\t",venseatfloat[test][loop][DISCOUNT][OCCUPIED]); pch=strtok_r(NULL, " ", &prog); strcpy(temp, pch); venseatfloat[test][loop][REGULAR][OCCUPIED]=(float)atof(pch); printf("%s is the string but %.3f is regular\n", temp ,venseatfloat[test][loop][DISCOUNT][OCCUPIED]); loop++; } output: >0.900000 is discount 0.75 is the string but 0.900 is regular >0.700000 is discount 0.65 is the string but 0.700 is regular What is going on?
