  • Design considerations on JSON schema for scalars with a consistent attachment property

    - by casperOne
    I'm trying to create a JSON schema for the results of doing statistical analysis based on disparate pieces of data. The current schema I have looks something like this: { // Basic key information. video : "http://www.youtube.com/watch?v=7uwfjpfK0jo", start : "00:00:00", end : null, // For results of analysis, to be populated: // *** This is where it gets interesting *** analysis : { game : { value: "Super Street Fighter 4: Arcade Edition Ver. 2012", confidence: 0.9725 } teams : [ { player : { value : "Desk", confidence: 0.95, } characters : [ { value : "Hakan", confidence: 0.80 } ] } ] } } The issue is the tuples that are used to store a value and the confidence related to that value (i.e. { value : "some value", confidence : 0.85 }), populated after the results of the analysis. This leads to a creep of this tuple for every value. Take a fully-fleshed out value from the characters array: { name : { value : "Hakan", confidence: 0.80 } ultra : { value: 1, confidence: 0.90 } } As the structures that represent the values become more and more detailed (and more analysis is done on them to try and determine the confidence behind that analysis), the nesting of the tuples adds great deal of noise to the overall structure, considering that the final result (when verified) will be: { name : "Hakan", ultra : 1 } (And recall that this is just a nested value) In .NET (in which I'll be using to work with this data), I'd have a little helper like this: public class UnknownValue<T> { T Value { get; set; } double? Confidence { get; set; } } Which I'd then use like so: public class Character { public UnknownValue<Character> Name { get; set; } } While the same as the JSON representation in code, it doesn't have the same creep because I don't have to redefine the tuple every time and property accessors hide the appearance of creep. Of course, this is an apples-to-oranges comparison, the above is code while the JSON is data. Is there a more formalized/cleaner/best practice way of containing the creep of these tuples in JSON, or is the approach above an accepted approach for the type of data I'm trying to store (and I'm just perceiving it the wrong way)? Note, this is being represented in JSON because this will ultimately go in a document database (something like RavenDB or elasticsearch). I'm not concerned about being able to serialize into the object above, because I can always use data transfer objects to facilitate getting data into/out of my underlying data store.

    I was reading this excellent blog article regarding speeding up the badge page and in the last comment the author @waffles (a.k.a Sam Saffron) mentions these tools: dapper and a bunch of custom helpers like rainbow, sql builder etc Dapper and sql builder was easy to look up but rainbow keeps pointing me to a CMS, can someone please point me to the real source? Thanks. Obviously the architecture of these [SE] sites is uber cool and ultra fast so no comments on that thanks.

  • When asked "How do I make a website?" how do you answer?

    - by Luke CK
    A (non-technical) friend of mine has asked me how to make a website. I get this question all the time. After a few questions I found out that she has an idea that could turn into a commercial site. I described three options to her: a) Get a book/enroll in a class/follow some online tutorials and learn how to do it. She's pretty smart and her personality seems like a good match for this sort of thing so I'm sure she could learn but she doesn't have a lot of time spare. Maybe if she started with one of those WYSIWYG editors at first? I stressed that this would take a longer than a couple of weekends of playing around. b) Hire someone to build it. Ranges from ultra cheap to ultra expensive, crappy to good and everything in between. I didn't mention sites like Rentacoder because she hasn't worked on a project like this before and doesn't know what to ask for. At this stage she'd likely ask for a Youtube-MySpace-Google for a few hundred bucks because she doesn't yet understand just how much is involved. c) Find someone technical and partner up with them. I explained that this can either work really well or be a disaster because she'd have to give up some of her ownership of the idea. How do you respond in these situations?

  • All the Gear and No Idea: Suggestions for re-designing my home/office/entertainment network

    - by 5arx
    Help/ Advice/ Suggestions please: I have a load of kit that I love but which currently operate in disconnected, sometimes counter-productive way. Because I never really had a masterplan I just added these things one after another and connected them up in ad hoc ways. Since I bought my Macbook I've found I spend much less time on the MacPro that was until then my main machine. Perversely, as my job involves writing .Net software, I spend a lot of Mac time actually inside a Windows 7 VM. I stream media from the HP box to the PS3 and thus to the TV, but its not without its limitations/annoyances. We listen to each other's iTunes libraries but the music files are all over the place and it would be good to know they were all safely in one location (and fully backed up). I need to come up with a strategy that will allow me to use all the kit for work, play (recording live music, making tunes, iMovie work), pushing/streaming media to the TV and sharing files with my other half (she uses a Windows laptop and her iPod touch). Ideally I'd like to be able to work on any of the machines and have a shared homedrive that was visible to all machines so all my current files were synced up wherever i was. It would be great if I could access everything securely and quickly over the web. I'd also like to be able to set up a background backup process. The kit list thus far: Apple MacPro 8GB/3x250GB RAID0 + 1TB Apple MacBook Pro 13" 8GB/250GB - I spend a lot of my work time on a Windows 7 VM on this. Crappy Acer laptop (for children's use - iPlayer, watching movies/tv files) HP Proliant Server 4GB/80GB+160GB+300GB Sun Ultra 10 2 x 80GB (old, but in top-notch condition) PS3 160GB iPod Classic 2 x 8GB iPod Touch Observations: Part of the problem is our dual use of Windows and OS X - we can't go for a pure NT style roaming profile. Because the server is also used for hosting test/beta applications and a SQL Server db, it can't be dedicated to file serving. The two Macs really could do with sharing a roaming profile or similar. I'd love to be able to do something useful with the Ultra 10. My other half has been trying to throw it away for over five years now and regularly ask what function it serves in my study :-( I've got no shortage of 500GB external USB hard drives iMovie files are very large and ideally would be processed on a RAID system. Apple's TimeMachine isn't so great. If anyone could suggest all or part of a setup that would fulfil some of my requirements I'd be very grateful. I am willing to consider purchasing one or two more bits of kit (an Apple TV and a Squeezebox have been moted by friends) if they will help make efficiencies rather than add to the chaos and confusion. Thanks for looking.

  • Network use of Gaming PC

    - by Matthew Patrick Cashatt
    Background After YEARS of waiting, I built the custom gaming PC of my dreams: Intel i7 - 975 Extreme Edition 3.3ghz (overclocked to 4.0) ATI Radeon 5970 2gb Corsair 256 gb SSD Drive 2 TB Sata II 3.0 7200rpm data drive 12 GB Kingston Hyper-X (1600mhz) DDR3 Windows 7 Ultra 64 bit And so on. . . Problem I hooked this beast up to our home theater and settled in for a great gaming season only to realize a couple of drawbacks: It's hard to accurately wax bad guys using a keyboard in your lap whilst reclined on your couch (and using a wireless keyboard). It's hard to read the text on the screen (i.e. menus, etc). I find that a 1:1 ratio (screen diagonal inch to inch away from screen) is optimum, but using the home theater, it's more like 1:3 which has me squinting unless I sit on the coffee table. The wife always seems to want the TV the same time I do and, unfortunately "Real Housewives of Beverly Hills" and Battlefield BC don't mix. I am losing the battle in the home theater room, but the PC has to stay there (long story). So, this leaves me with the option of playing in my home office which is about 30 feet away from the home theater. I am a software developer so I have a pretty decent set up in my office--multiple 1080p monitors, HP Envy 17 which can run games like Crysis in 720p with out stammering too much. Also, I can game very comfortably at my desk in the office. Still, even though the set up in my office can run games well enough, I don't want to regress to that when I have worked YEARS for an awesome gaming PC that can run everything on ultra high settings. My Question What are my options for running my games on the beastly desktop in the Home Theater, but physically playing in my office about 30 feet away? A really long HDMI cable? LAN/RDC? Details that May Help We have an open crawlspace so running cable from HT room to office is no problem. I already have networked the house with a LAN Any help is GREATLY appreciated. Thanks, Matt

  • How to mount a USB thumb drive as "Fixed" instead of "Removable"

    - by AMissico
    I have over 8 GB in my "Code Library" that I maintain on a 64 GB ScanDisk Ultra Backup USB Device. Windows Search 4.0 (installed on Windows XP) can index removable drives, but Windows 7 (which uses Windows Search 4.0) cannot, because the USB device identifies itself as a Removable drive and Windows 7 refuses to index removable drives. How can I mount the USB Thumb Drive as Fixed instead of Removable?

  • What's the max Windows 7 access possible to restrict tampering with single service?

    - by Crawford Comeaux
    I'm developing an ADHD management system for myself. Without going into detail (and as silly as it may sound for a grown man to need something like this), I need to build a me-proof service to run on my Windows 7 Ultra laptop. I still need fairly complete access to the system, though. How can I set things up so that I'm unable to "easily" (ie. within 3-5 mins without rebooting) stop the service or prevent it from running?
