  • How do you deal with duplicate street suffixes?

    - by Matt
    I have a system where users need to enter addresses. I am trying to limit duplicates of course and something I started noticing was becoming a big problem was some users putting in "Road" and others "Rd", therefore duplicates were creeping in. I looked up the list of USPS street suffix abbreviations but I still have a question which I can't find an answer to. Can I replace all words in a street address with the USPS standard abbreviation? An example would be "123 Forest Hill Road". If I were to replace it with the abbreviations it would then be "123 Frst Hl Rd" or does the "street suffix" that USPS is referring to mean they only want you to make go as far as "123 Forest Hill Rd"?

  • A quick over view of facebook's db?

    - by Matt
    Hey guys I find it hard to believe that Facebook uses simple sql, surely it would use some other method but lets assume for now it does use sql how would the code assimilating the 'wall' work? Lets say that there is three tables (just for the example) Friends: id (entry key) - uid(your id) - fid (your mates' id) Wall:id (entry key) - username - comment - time - commentcount comments: id (entry key) - wid (wall id (original comment)) - reply - time Lets forget about the like part and report etc, as well as mod things (ip, ban etc.) How would this work? Select wall.id, wall.username, wall.comment, wall.time, wall.commentcount, comments.wid, comments.reply, comments.time FROM wall inner join comments ON wall.id=comments.wid ORDER BY wall.time; That's your own wall but how do they get friend's? A heap of unions?

  • VBA: Difference in two ways of declaring a new object? (Trying to understand why my solution works)

    - by Matt
    I was creating a new object within a loop, and adding that object to a collection; but when I read back the collection after, it was always filled entirely with the last object I had added. I've come up with two ways around this, but I simply do not understand why my initial implementation was wrong. Original: Dim oItem As Variant Dim sOutput As String Dim i As Integer Dim oCollection As New Collection For i = 0 To 10 Dim oMatch As New clsMatch oMatch.setLineNumber i oCollection.Add oMatch Next For Each oItem In oCollection sOutput = sOutput & "[" & oItem.lineNumber & "]" Next MsgBox sOutput This resulted in every lineNumber being 10; I was obviously not creating new objects, but instead using the same one each time through the loop, despite the declaration being inside of the loop. So, I added Set oMatch = Nothing immediately before the Next line, and this fixed the problem, it was now 0 to 10. So if the old object was explicitly destroyed, then it was willing to create a new one? I would have thought the next iteration through the loop would cause anything declared within the loop do be destroyed due to scope? Curious, I tried another way of declaring a new object: Dim oMatch As clsMatch: Set oMatch = New clsMatch. This, too, results in 0 to 10. Can anyone explain to me why the first implementation was wrong?

  • Which are the most important media queries to use in creating mobile responsive design?

    - by Matt
    There are a lot different media queries for mobile screen sizes. It can be overwhelming to accomodate all of them when designing a responsive mobile site. Which are the most important ones to use when designing for mobile? I found this article that does a pretty good job of outlining the available media queries: http://css-tricks.com/snippets/css/media-queries-for-standard-devices/. /* Smartphones (portrait and landscape) ----------- */ @media only screen and (min-device-width : 320px) and (max-device-width : 480px) { /* Styles */ } /* Smartphones (landscape) ----------- */ @media only screen and (min-width : 321px) { /* Styles */ } /* Smartphones (portrait) ----------- */ @media only screen and (max-width : 320px) { /* Styles */ } /* iPads (portrait and landscape) ----------- */ @media only screen and (min-device-width : 768px) and (max-device-width : 1024px) { /* Styles */ } /* iPads (landscape) ----------- */ @media only screen and (min-device-width : 768px) and (max-device-width : 1024px) and (orientation : landscape) { /* Styles */ } /* iPads (portrait) ----------- */ @media only screen and (min-device-width : 768px) and (max-device-width : 1024px) and (orientation : portrait) { /* Styles */ } /* Desktops and laptops ----------- */ @media only screen and (min-width : 1224px) { /* Styles */ } /* Large screens ----------- */ @media only screen and (min-width : 1824px) { /* Styles */ } /* iPhone 4 ----------- */ @media only screen and (-webkit-min-device-pixel-ratio : 1.5), only screen and (min-device-pixel-ratio : 1.5) { /* Styles */ }

  • XML Serializing a class with a Dictionary<string, List<string>> object

    - by Matt
    Is it possible to implement IXmlSerializable and in my XML file capture an object of type Dictionary ? I have the following public class coolio : IXmlSerializable { private int a; private bool b; private string c; private Dictionary<string, List<string>> coco; public coolio(int _a, bool _b, string _c, Dictionary<string, List<string>> _coco) { a=_a; b=_b; c=_c; coco=_coco; } public System.Xml.Schema.XmlSchema GetSchema() { return null; } public void WriteXml(XmlWriter writer) { const string myType = "coolio"; writer.WriteStartElement(myType); writer.WriteAttributeString("a", a.ToString()); writer.WriteAttributeString("b", b.ToString()); writer.WriteAttributeString("c", c); // How do I add a subelement for Dictionary<string, List<string>> coco? writer.WriteEndElement(); } public void ReadXml(XmlReader reader) { if (reader.MoveToContent() != XmlNodeType.Element || reader.LocalName != "coolio") return; a= int.Parse(reader["a"]); b = bool.Parse(reader["b"]); c= reader["c"]; // How do I read subelement into Dictionary<string, List<string>> coco? } } But I am stumped as to how I could add the Dictionary (XML seriliazed to my XML file)

  • My chance to shape our development process/policy

    - by Matt Luongo
    Hey guys, I'm sorry if this is a duplicate, but the question search terms are pretty generic. I work at a small(ish) development firm. I say small, but the company is actually a fair size; however, I'm only the second full-time developer, as most past work has been organized around contractors. I'm in a position to define internal project process and policy- obvious stuff like SCM and unit-testing. Methodology is outside the scope of the document I'm putting together, but I'd really like to push us in a leaner (and maybe even Agile?) direction. I feel like I have plenty of good practice recommendations, but not enough solid motivation to make my document the spirit guide I'd like it to be. I've separated the document into "principles" and "recommendations". Recommendations have been easy to come up with. Use SCM, strive for 1-step, regularly scheduled builds, unit test first, document as you go... Listing the principles that are supposed to be informing these recommendations, though, has been rough. I've come up with "tools work for us; we should never work for tools" and a hazy clause aimed at our QA (which has been overly manual) that I'd like to read "tedium is the root of all evil". I don't want to miss an opportunity with this document to give us a good in-house start and maybe even push us toward Agile. What principles am I missing?

  • Best way to store 3 pieces of data as a single entry

    - by Matt
    For a game server, I want to record details when a player makes a kill, store this, and then at intervals update to a sql database. The part i'm interested in right now is the best method of storing the kill information. What i'd like to pass to the sql server on update would be {PlayerName, Kills, Deaths}, where the kills and deaths are a sum for the period between updates. So i'm assuming i'd build a list along the lines of {bob, 1, 0} {frank, 0, 1} {tom, 1, 0} {frank, 0, 1} then on update, consolidate the list to {frank, 14, 3}etc Can someone offer some advice please?

  • Maximizing the number of threads to fully utilize all available resources without hindering overall

    - by Matt
    Let's say I have to generate a bunch of result files, and I want to make it as fast as possible. Each result file is generated independently of any other result file; in fact, one could say that each result file is agnostic to every other result file. The resources used to generate each result file is also unique to each. How can I dynamically decide the optimal number of threads to run simultaneously in order to minimize the overall run time? Is my only option to write my own thread manager that watches performance counters and adjust accordingly or does there exists some solid classes that already accomplish this?

  • jQuery rotator not rotating properly - too much recursion

    - by Matt Nathanson
    I've built a custom jQuery rotator using just basic animation to rotate the 3 Divs (images). I've built the function and then reinitiate the function using it as a call back. Here's the code: function ImageRotate() { var CurrentFeature = "#container" + featureNumber; $(CurrentFeature).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); var featureNumber2 = featureNumber-1; if ( featureNumber == 1) {featureNumber2=3} var CurrentFeature2 = "#container" + featureNumber2; $(CurrentFeature2).stop(false, true).delay(4500).animate({'top' : '0px'}, 3000); $('#container2').stop(false, true).delay(4500).animate({'top' : '-330px'}, 25); var featureNumber3 = featureNumber+1; if ( featureNumber == 3){featureNumber3=1} var CurrentFeature3 = "#container" + featureNumber3; $(CurrentFeature3).stop(false, true).delay(7500).animate({'top' : '0px'}, 3000); $(CurrentFeature2).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); $(CurrentFeature).stop(false, true).delay(4500).animate({'top' : '-330px'}, 25); if (featureNumber ==1) {featureNumber=3} else{featureNumber--}; $(CurrentFeature).stop(false, true).delay(7500).animate({'top' : '0px'}, 3000); $(CurrentFeature3).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); $(CurrentFeature2).stop(false, false).delay(4500).animate({'top' : '-330px'}, 25,ImageRotate()); }; It's worth noting that when calling the function again I also tried making another function called ImageRotate2(); and it did the same thing. It loops, but i get all sorts of funkiness. Edit: I've also tried some answers in the replies and they both leave me with recursion errors each second.

  • Recommended reading for bioinformatics

    - by Matt
    I'm keen on learning about bioinformatics. I am ideally looking for a short course introduction, with some practical tasks I can get my teeth into immediately to see if there is any interest in it for me. I already have a good understanding of molecular biology, so I should be able to skip most of the foundational work. Any suggestions?

  • How do I ensure a Flex dataProvider processes the data synchronously?

    - by Matt Calthrop
    I am using an component, and currently have a dataProvider working that is an ArrayCollection (have a separate question about how to make this an XML file... but I digress). Variable declaration looks like this: [Bindable] private var _dpImageList : ArrayCollection = new ArrayCollection([ {"location" : "path/to/image1.jpg"}, {"location" : "path/to/image2.jpg"}, {"location" : "path/to/image3.jpg"} ]); I then refer to like this: <s:List id="lstImages" width="100%" dataProvider="{_dpImageList}" itemRenderer="path.to.render.ImageRenderer" skinClass="path.to.skins.ListSkin" > <s:layout> <s:HorizontalLayout gap="2" /> </s:layout> </s:List> Currently, it would appear that each item is processed asynchronously. However, I want them to be processed synchronously. Reason: I am displaying a list of images, and I want the leftmost one rendered first, followed by the one to its right, and so on. Edit: I just found this answer. Do you think that could be the same issue?

  • Any C/C++ to non-native bytecode compiler/interpreters?

    - by Matt
    As the title indicates, are there any C/C++ bytecode compilers/interpreters? I'm writing an application in an interpreted language that depends on certain libraries that are fully cross-compilable (there are no special flags to indicate code changes during compilation for a certain platform) but are written in C and C++. Rather than shipping n-platform-specific-libs with each platform, it would be nice to ship one set of libs which are interpreted by one platform specific interpreter. Possible and/or available?

  • R selecting duplicate rows

    - by Matt
    Okay, I'm fairly new to R and I've tried to search the documentation for what I need to do but here is the problem. I have a data.frame called heeds.data in the following form (some columns omitted for simplicity) eval.num, eval.count, ... fitness, fitness.mean, green.h.0, green.v.0, offset.0, green.h.1, green.v.1,...green.h.7, green.v.7, offset.7... And I have selected a row meeting the following criteria: best.fitness <- min(heeds.data$fitness.mean[heeds.data$eval.count = 10]) best.row <- heeds.data[heeds.data$fitness.mean == best.fitness] Now, what I want are all of the other rows with that have columns green.h.0 to offset.7 (a contiguous section of columns) equal to the best.row Basically I'm looking for rows that have some of the conditions the same as the "best" row. I thought I could just do this, heeds.best <- heeds.data$fitness[ heeds.data$green.h.0 == best.row$green.h.0 & ... ] But with 24 columns it seems like a stupid method. Looking for something a bit simpler with less manual typing. Thanks!

  • Screen information while Windows system is locked (.NET)

    - by Matt
    We have a nightly process that updates applications on a user's pc, and that requires bringing the application down and back up again (not looking to get into changing that process). The problem is that we are building a Windows AppBar on launch which requires a valid screen, and when the system is locked there isn't one in the Screen class. So none of the visual effects are enabled and it shows up real ugly. The only way we currently have around this is to detect a locked screen and just spin and wait until the user unlocks the desktop, then continue launching. Leaving it down isn't an option, as this is a key part of our user's workflow, and they expect it to be up and running if they left it that way the night before. Any ideas?? I can't seem to find the display information anywhere, but it has to be stored off someplace, since the user is still logged in. The contents of the Screen.AllScreens array: ** When Locked: Device Name : DISPLAY Primary : True Bits Per Pixel : 0 Bounds : {X=-1280,Y=0,Width=2560,Height=1024} Working Area : {X=0,Y=0,Width=1280,Height=1024} ** When Unlocked: Device Name : \\.\DISPLAY1 Primary : True Bits Per Pixel : 32 Bounds : {X=0,Y=0,Width=1280,Height=1024} Working Area : {X=0,Y=0,Width=1280,Height=994} Device Name : \\.\DISPLAY2 Primary : False Bits Per Pixel : 32 Bounds : {X=-1280,Y=0,Width=1280,Height=1024} Working Area : {X=-1280,Y=0,Width=1280,Height=964}

  • Objective-C method not being called

    - by Matt S.
    It's either because of the fact I'm tired or because I'm doing it wrong, but for some reason I can't get it to call a method. Here's what I'm trying to call: -(void)newHighScore:(int)d Which right now just does an NSLog saying "yea I'm working!" I'm calling it like this: [highscore newHighScore:score]; highscore is what I called the HighScore class in the .h, and score is an int with the score.
