• Need to kill a session?

  - by rob - not a robber

  Really quick here... I think I have the answer, but just looking for some validation. I have a site with two "points of entry." One is for a standard user and one is for an admin account. In the real world, an admin could have a standard user account and try to login as an admin while already being under the standard user session. I have two separate front ends to facilitate login. The normal user one is frilly and has ads and the like, the admin one is strictly business, so any suggestion to have the two user types login through the same "door" is not on the table. Would you advise on the admin login page to destroy any active sessions? Once the admin is in, they'll only be tooling around in their admin area and not on the main site. Has anyone run into probs using this method and having an admin-type user try to log back in in a new window as a "user" to view changes from a logged in user's prespective? Thanks in advance. So many cans of worms :)

• Google Analytics API Authentication Speedup

  - by Paulo

  I'm using a Google Analytics API Class in PHP made by Doug Tan to retrieve Analytics data from a specific profile. Check the url here: http://code.google.com/intl/nl/apis/analytics/docs/gdata/gdataArticlesCode.html When you create a new instance of the class you can add the profile id, your google account + password, a daterange and whatever dimensions and metrics you want to pick up from analytics. For example i want to see how many people visited my website from different country's in 2009. //make a new instance from the class $ga = new GoogleAnalytics($email,$password); //website profile example id $ga->setProfile('ga:4329539'); //date range $ga->setDateRange('2010-02-01','2010-03-08'); //array to receive data from metrics and dimensions $array = $ga->getReport( array('dimensions'=>('ga:country'), 'metrics'=>('ga:visits'), 'sort'=>'-ga:visits' ) ); Now you know how this API class works, i'd like to adress my problem. Speed. It takes alot of time to retrieve multiple types of data from the analytics database, especially if you're building different arrays with different metrics/dimensions. How can i speed up this process? Is it possible to store all the possible data in a cache so i am able to retrieve the data without loading it over and over again?

• Anyone got a nifty credit expiry algorithm?

  - by garethkeenan

  Our website uses a credit system to allow users to purchase inexpensive digital goods (eg. photos). We use credits, rather than asking the user to pay for items individually, because the items are cheap and we are trying to keep our credit-card/PayPal overhead low. Because we aren't a bank, we have to expire credits after a certain amount of time. We expire deposit credits after a year, but other types of credits (bonuses, prizes, refunds) may have a different shelf-life. When a buyer buys an item, we spend the credit that is going to expire first. Our current system keeps track of every deposit by storing the original value and the remainder to be spent. We keep a list of all purchases as well, of course. I am currently moving to a system which is much more like a traditional double-entry accounting system. A deposit will create a ledger item, increasing the user's 'spending' account balance. Every purchase will also create a ledger item, decreasing the user's 'spending' account balance. The new system has running balances, while the old system does not, which greatly improves our ability to find problems and do reconciliations. We do not want to use the old system of keeping a 'remainder' value attached to each deposit record because it is inefficient to replay a user's activities to calculate what the remainder of each deposit is over time (for the user's statement). So, after all of this verbose introduction, my question is "Does anyone else out there have a similar system of expiring credits?" If you could describe how you calculate expired credits it would be a great help. If all expired credits had the exact same shelf life, we would be able to calculate the expired amount using: Total Deposits - Total Spending - Deposits Not Due To Expire = Amount to Expire However, because deposits can have different shelf lives, this formula does not work because more than one deposit can be partially spent at any given time.

• Trying to use linq to search based on table with hierarchical data.

  - by Steph

  Duplicate many times over (and also these) I have a table called Types that has the following columns. ID Level Name ParentID (The ID of the parent row) and a table called ParentObject which has the following columns. ID TypeID there are 4 different level (possibly to be expanded to more). So if I had ID: 1 Level: 0 Name: Level0 ParentID: null ID: 2 Level: 1 Name: Level1 ParentID: 1 ID: 3 Level: 2 Name: Level2 ParentID: 2 ID: 4 Level: 3 Name: Level3 ParentID: 3 ID: 5 Level: 4 Name: Level4 ParentID: 4 In the ParentObject table I store the tree by just storing the lowest level ID. So if the ID i have is 4, I know that the tree actually goes Level0 - Level1 - Level2 - Level3 Basically, I need to be able to search all objects for a certain Type, or Type Level 2 for example in a linq statement. Say that the TypeID stored in the ParentObject table is 4, so Level3. But I actually want to search for all ParentObjects where the Level 2 type has an ID of 3. What would be the best way to do this since the id stored could be a level1 or a level2, etc.? Preferably in one linq statement if possible.

• Google Radar Chart: Not plotting data

  - by Hallik

  Hi. I have different types of data that I have normalized just with base10, so everything is on a 10 point scale. There are two data points, and the legend for them show up fine. All the points around the radar show up fine and so do the labels for them, but I don't see any filled in data. Outside of the labels and axis, the chart is blank. Below is the actual image tag I render, then I split up the variables on each line for easy readability. Anyone mind telling me why it isn't working? <img src="http://chart.apis.google.com/chart?cht=rs&amp;chm=B,3366CC60,0,1.0,5.0|B,CC4D3360,1,1.0,5.0&chs=600x500&chd=t:4.6756775443385,4.7031365524912,1.8646655408171,1.8358167047079,4.2483837215455,4.1367786166752,|5.0319252700625,5.0370797208146,1.8415340693163,1.8591105937857,4.3392150450337,4.1434876641017&chco=3366CC,CC4D33&chls=2.0,4.0,0.0|2.0,4.0,0.0&chxt=x&chxl=0:|Label1|Label2|label3|Label4|Label5|Label6&chxr=0,0.0,10.0&chdl=Data Object 1|Data Object 2&"/> cht=rs& chm=B,3366CC60,0,1.0,5.0|B,CC4D3360,1,1.0,5.0& chs=600x500& chd=t:4.6756775443385,4.7031365524912,1.8646655408171,1.8358167047079,4.2483837215455,4.1367786166752,|5.0319252700625,5.0370797208146,1.8415340693163,1.8591105937857,4.3392150450337,4.1434876641017& chco=3366CC,CC4D33& chls=2.0,4.0,0.0|2.0,4.0,0.0& chxt=x& chxl=0:|Label1|Label2|label3|Label4|Label5|Label6& chxr=0,0.0,10.0& chdl=Data Object 1|Data Object 2& This is the radar chart page, I can't tell what I am doing wrong. http://code.google.com/apis/chart/docs/gallery/radar_charts.html

• Where are tables in Mnesia located?

  - by Sanoj

  I try to compare Mnesia with more traditional databases. As I understand it tables in Mnesia can be located to: ram_copies - tables are stored in RAM only, so no durability as in ACID. disc_copies - tables are located on disc and a copy is located in RAM, so the table can not be bigger than the available memory? disc_only_copies - tables are located to disc only, so no caching in memory and worse performance? And the size of the table are limited to the size of dets or the table has to be fragmented. So if I want the performance of doing reads from RAM and the durability of writes to disc, then the size of the tables are very limited compared to a traditional RDBMS like MySQL or PostgreSQL. I know that Mnesia aren't meant to replace traditional RDBMS:s, but can it be used as a big RDBMS or do I have to look for another database? The server I will use is a VPS with limited amount of memory, around 512MB, but I want good database performance. Are disc_copies and the other types of tables in Mnesia so limited as I have understood?

• Different location of assemblies stoped the type casting.

  - by smwikipedia

  I am writing a custom Control class in C# for my main project. There're 2 projects, one for my Control and one for my main project. These 2 projects are in the same solution. I add a reference from my main project to my Control project. I notice that the first time after I drag my Control from the Tool Panel onto my main winform, an assembly folder was generated at the C:\Users\XXX\AppData\Local\Microsoft\VisualStudio\9.0\ProjectAssemblies, and the folder name is something like "jlebh-py01". The first build is always OK, but after I rebuild my Control class or whole solution, a new assembly folder will be generated at C:\Users\XXX\AppData\Local\Microsoft\VisualStudio\9.0\ProjectAssemblies, and then problem arises, my Control fails to behave well because Visual Studio says that the two types "originates from different location". The error message is as below: [A]MyControl.TypeXXX cannot be cast to [B]MyControl.TypeXXX. Type A orginates from assemblyXXX at location 'C:\Users\XXX\AppData\Local\Microsoft\VisualStudio\9.0\ProjectAssemblies\jlebh-py01\MyControl.dll' Type B originats from assemblyXXX at location 'C:\Users\XXX\AppData\Local\Microsoft\VisualStudio\9.0\ProjectAssemblies\ue4i-z3j01\MyControl.dll' If I reference the Control DLL directly instead of through project reference, or never rebuild the Control project after use my Control in the main project, things seem to be OK. Does anyone knows why? Is it the proper way to develop a control and a main project within the same solution? Many thanks...

• Some general C questions.

  - by b-gen-jack-o-neill

  Hello. I am trying to fully understand the process pro writing code in some language to execution by OS. In my case, the language would be C and the OS would be Windows. So far, I read many different articles, but I am not sure, whether I understand the process right, and I would like to ask you if you know some good articles on some subjects I couldn´t find. So, what I think I know about C (and basically other languages): C compiler itself handles only data types, basic math operations, pointers operations, and work with functions. By work with functions I mean how to pass argument to it, and how to get output from function. During compilation, function call is replaced by passing arguments to stack, and than if function is not inline, its call is replaced by some symbol for linker. Linker than find the function definition, and replace the symbol to jump adress to that function (and of course than jump back to program). If the above is generally true and I get it right, where to final .exe file actually linker saves the functions? After the main() function? And what creates the .exe header? Compiler or Linker? Now, additional capabilities of C, today known as C standart library is set of functions and the declarations of them, that other programmers wrote to extend and simplify use of C language. But these functions like printf() were (or could be?) written in different language, or assembler. And there comes my next question, can be, for example printf() function be written in pure C without use of assembler? I know this is quite big question, but I just mostly want to know, wheather I am right or not. And trust me, I read a lots of articles on the web, and I would not ask you, If I could find these infromation together on one place, in one article. Insted I must piece by piece gather informations, so I am not sure if I am right. Thanks.

• attachment_fu and RMagick

  - by trobrock

  After finally getting RMagick installed on my Mac I have set up attachment_fu according to the tutorial here: http://clarkware.com/cgi/blosxom/2007/02/24#FileUploadFu&gt when I try and upload a file via the upload form I get around 80 messages like these: /Library/Ruby/Gems/1.8/gems/rmagick-2.13.1/lib/RMagick.rb:44: warning: already initialized constant PercentGeometry /Library/Ruby/Gems/1.8/gems/rmagick-2.13.1/lib/RMagick.rb:45: warning: already initialized constant AspectGeometry /Library/Ruby/Gems/1.8/gems/rmagick-2.13.1/lib/RMagick.rb:46: warning: already initialized constant LessGeometry /Library/Ruby/Gems/1.8/gems/rmagick-2.13.1/lib/RMagick.rb:47: warning: already initialized constant GreaterGeometry I did some searching and found that this problem can arise when you require RMagick twice in an application using different casing for the require statement: http://work.rowanhick.com/2007/12/19/require-rmagick-and-case-sensitivity/ I am not requiring it myself, but I was thinking maybe with the config.gem "rmagick" line in my environment.rb file rails might be requiring it. After the form submits it gives me a validation error of: Content type is not included in the list I have checked the source for attachement_fu and found the image/png in the list of content types so I don't believe that is the proper error message: http://github.com/technoweenie/attachment_fu/blob/master/lib/technoweenie/attachment_fu.rb Does anyone have any ideas on how I can get this to work?

• Reading CSV files in numpy where delimiter is ","

  - by monch1962

  Hello all, I've got a CSV file with a format that looks like this: "FieldName1", "FieldName2", "FieldName3", "FieldName4" "04/13/2010 14:45:07.008", "7.59484916392", "10", "6.552373" "04/13/2010 14:45:22.010", "6.55478493312", "9", "3.5378543" ... Note that there are double quote characters at the start and end of each line in the CSV file, and the "," string is used to delimit fields within each line. When I try to read this into numpy via: import numpy as np data = np.genfromtxt(csvfile, dtype=None, delimiter=',', names=True) all the data gets read in as string values, surrounded by double-quote characters. Not unreasonable, but not much use to me as I then have to go back and convert every column to its correct type When I use delimiter='","' instead, everything works as I'd like, except for the 1st and last fields. As the start of line and end of line characters are a single double-quote character, this isn't seen as a valid delimiter for the 1st and last fields, so they get read in as e.g. "04/13/2010 14:45:07.008 and 6.552373" - note the leading and trailing double-quote characters respectively. Because of these redundant characters, numpy assumes the 1st and last fields are both String types; I don't want that to be the case Is there a way of instructing numpy to read in files formatted in this fashion as I'd like, without having to go back and "fix" the structure of the numpy array after the initial read?

• Create a VPN with Python

  - by user213060

  I want to make a device "tunnel box" that you plug an input ethernet line, and an output ethernet line, and all the traffic that goes through it gets modified in a special way. This is similar to how a firewall, IDS, VPN, or similar boxes are connected inline in a network. I think you can just assume that I am writing a custom VPN in Python for the purpose of this question: LAN computer <--\ LAN computer <---> [LAN switch] <--> ["tunnel box"] <--> [internet modem] <--> LAN computer <--/ My question is, what is a good way to program this "tunnel box" from python? My application needs to see TCP flows at the network layer, not as individual ethernet frames. Non-TCP/IP traffic such as ICPM and other types should just be passed through. Example Twisted-like Code for my "tunnel box" tunnel appliance: from my_code import special_data_conversion_function class StreamInterceptor(twisted.Protocol): def dataReceived(self,data): data=special_data_conversion_function(data) self.outbound_connection.send(data) My initial guesses: TUN/TAP with twisted.pair.tuntap.py - Problem: This seems to only work at the ethernet frame level, not like my example? Socks proxy - Problem: Not transparent as in my diagram. Programs have to be specifically setup for it. Thanks!

• Compiler optimization causing the performance to slow down

  - by aJ

  I have one strange problem. I have following piece of code: template<clss index, class policy> inline int CBase<index,policy>::func(const A& test_in, int* srcPtr ,int* dstPtr) { int width = test_in.width(); int height = test_in.height(); double d = 0.0; //here is the problem for(int y = 0; y < height; y++) { //Pointer initializations //multiplication involving y //ex: int z = someBigNumber*y + someOtherBigNumber; for(int x = 0; x < width; x++) { //multiplication involving x //ex: int z = someBigNumber*x + someOtherBigNumber; if(soemCondition) { // floating point calculations } *dstPtr++ = array[*srcPtr++]; } } } The inner loop gets executed nearly 200,000 times and the entire function takes 100 ms for completion. ( profiled using AQTimer) I found an unused variable double d = 0.0; outside the outer loop and removed the same. After this change, suddenly the method is taking 500ms for the same number of executions. ( 5 times slower). This behavior is reproducible in different machines with different processor types. (Core2, dualcore processors). I am using VC6 compiler with optimization level O2. Follwing are the other compiler options used : -MD -O2 -Z7 -GR -GX -G5 -X -GF -EHa I suspected compiler optimizations and removed the compiler optimization /O2. After that function became normal and it is taking 100ms as old code. Could anyone throw some light on this strange behavior? Why compiler optimization should slow down performance when I remove unused variable ? Note: The assembly code (before and after the change) looked same.

• IIS: How to get the Metabase path?

  - by Ian Boyd

  i'm trying to get the list of mime types known to an IIS server (which you can see was asked and and answered by me 2 years ago). The copy-pasted answer involves: GetObject("IIS://LocalHost/MimeMap") msdn GetObject("IIS://localhost/mimemap") KB246068 GetObject("IIS://localhost/MimeMap") Scott Hanselman's Blog new DirectoryEntry("IIS://Localhost/MimeMap")) Stack Overflow new DirectoryEntry("IIS://Localhost/MimeMap")) Stack Overflow New DirectoryServices.DirectoryEntry("IIS://localhost/MimeMap") Velocity Reviews You get the idea. Everyone agrees that you use a magical path iis://localhost/mimemap. And this works great, except for the times when it doesn't. The only clue i can find as to why it fails, is from an IIS MVP, Chris Crowe's, blog: string ServerName = "LocalHost"; string MetabasePath = "IIS://" + ServerName + "/MimeMap"; // Note: This could also be something like // string MetabasePath = "IIS://" + ServerName + "/w3svc/1/root"; DirectoryEntry MimeMap = new DirectoryEntry(MetabasePath); There are two clues here: He calls iis://localhost/mimemap the Metabase Path. Which sounds to me like it is some sort of "path" to a "metabase". He says that the path to the metabase could be something else; and he gives an example of what it could be like. Right now i, and the entire planet, are hardcoding the "MetabasePath" as iis://localhost/MimeMap What should it really be? What should the code be doing to construct a valid MetabasePath? Note: i'm not getting an access denied error, the error is the same when you have an invalid MetabasePath, e.g. iis://localhost/SoTiredOfThis

• Why does Java's invokevirtual need to resolve the called method's compile-time class?

  - by Chris

  Consider this simple Java class: class MyClass { public void bar(MyClass c) { c.foo(); } } I want to discuss what happens on the line c.foo(). At the bytecode level, the meat of c.foo() will be the invokevirtual opcode, and, according to the documentation for invokevirtual, more or less the following will happen: Look up the foo method defined in compile-time class MyClass. (This involves first resolving MyClass.) Do some checks, including: Verify that c is not an initialization method, and verify that calling MyClass.foo wouldn't violate any protected modifiers. Figure out which method to actually call. In particular, look up c's runtime type. If that type has foo(), call that method and return. If not, look up c's runtime type's superclass; if that type has foo, call that method and return. If not, look up c's runtime type's superclass's superclass; if that type has foo, call that method and return. Etc.. If no suitable method can be found, then error. Step #3 alone seems adequate for figuring out which method to call and verifying that said method has the correct argument/return types. So my question is why step #1 gets performed in the first place. Possible answers seem to be: You don't have enough information to perform step #3 until step #1 is complete. (This seems implausible at first glance, so please explain.) The linking or access modifier checks done in #1 and #2 are essential to prevent certain bad things from happening, and those checks must be performed based on the compile-time type, rather than the run-time type hierarchy. (Please explain.)

• Getting values from DataGridView back to XDocument (using LINQ-to-XML)

  - by Pretzel

  Learning LINQ has been a lot of fun so far, but despite reading a couple books and a bunch of online resources on the topic, I still feel like a total n00b. Recently, I just learned that if my query returns an Anonymous type, the DataGridView I'm populating will be ReadOnly (because, apparently Anonymous types are ReadOnly.) Right now, I'm trying to figure out the easiest way to: Get a subset of data from an XML file into a DataGridView, Allow the user to edit said data, Stick the changed data back into the XML file. So far I have Steps 1 and 2 figured out: public class Container { public string Id { get; set; } public string Barcode { get; set; } public float Quantity { get; set; } } // For use with the Distinct() operator public class ContainerComparer : IEqualityComparer<Container> { public bool Equals(Container x, Container y) { return x.Id == y.Id; } public int GetHashCode(Container obj) { return obj.Id.GetHashCode(); } } var barcodes = (from src in xmldoc.Descendants("Container") where src.Descendants().Count() > 0 select new Container { Id = (string)src.Element("Id"), Barcode = (string)src.Element("Barcode"), Quantity = float.Parse((string)src.Element("Quantity").Attribute("value")) }).Distinct(new ContainerComparer()); dataGridView1.DataSource = barcodes.ToList(); This works great at getting the data I want from the XML into the DataGridView so that the user has a way to manipulate the values. Upon doing a Step-thru trace of my code, I'm finding that the changes to the values made in DataGridView are not bound to the XDocument object and as such, do not propagate back. How do we take care of Step 3? (getting the data back to the XML) Is it possible to Bind the XML directly to the DataGridView? Or do I have to write another LINQ statement to get the data from the DGV back to the XDocument? Suggstions?

• C# Setting Properties using Index

  - by Guazz

  I have a business class that contains many properties for various stock-exchange price types. This is a sample of the class: public class Prices { public decimal Today {get; set} public decimal OneDay {get; set} public decimal SixDay {get; set} public decimal TenDay {get; set} public decimal TwelveDay {get; set} public decimal OneDayAdjusted {get; set;} public decimal SixDayAdjusted {get; set;} public decimal TenDayAdjusted {get; set;} public decimal OneHundredDayAdjusted {get; set;} } I have a legacy system that supplies the prices using string ids to identify the price type. E.g. Today = "0D" OneDay = "1D" SixDay = "6D" //..., etc. Firstly, I load all the values to an IDictionary() collection so we have: [KEY] VALUE [0D] = 1.23456 [1D] = 1.23456 [6D] = 1.23456 ...., etc. Secondly, I set the properties of the Prices class using a method that takes the above collection as a parameter like so: SetPricesValues(IDictionary<string, decimal> pricesDictionary) { // TODAY'S PRICE string TODAY = "D0"; if (true == pricesDictionary.ContainsKey(TODAY)) { this.Today = pricesDictionary[TODAY]; } // OneDay PRICE string ONE_DAY = "D1"; if (true == pricesDictionary.ContainsKey(ONE_DAY)) { this.OneDay = pricesDictionary[ONE_DAY]; } //..., ..., etc., for each other property } Is there a more elegant technique to set a large amount of properties? Thanks, j

• jQuery Autocomplete Json Ajax cross browser issue with Google Search Appliance

  - by skyfoot

  I am implementing a jquery autocomplete on a search form and am getting the suggestions from the Google Search Appliance Autocomple suggestions service which returns a result set in json. What I am trying to do is go off to the GSA to get suggestions when the user types something in the search box. The url to get the json suggestions is as follows: http://gsaurl/suggest?q=<query>&max=10&site=default_site&client=default_frontend&access=p&format=rich The json which is returned is as follows: { "query":"re", "results": [ {"name":"red", "type":"suggest"}, {"name":"read", "type":"suggest"}] } The jQuery autocomplete code is as follows: $(#q).autocomplete(searchUrl, { width: 320, dataType: 'json', highlight: false, scroll: true, scrollHeight: 300, parse: function(data) { var array = new Array(); for(var i=0;i<data.results.length;i++) { array[i] = { data: data.results[i], value: data.results[i].name, result: data.results[i].name }; } return array; }, formatItem: function(row) { return row.name; } }); This works in IE but fails in firefox as the data returned in the parse function is null. Any ideas why this would be the case? Workaround I created an aspx page to call the GSA suggest service and to return the json from the suggest service. Using this page as a proxy and setting it as the url in the jQuery autocomplete worked in both IE and FireFox.

• vestal_versions : problem with column named changes

  - by arkannia

• Listing all possible values for SOAP enumeration with Python SUDS

  - by bdk

  I'm connecting with a SUDS client to a SOAP Server whose wsdl contains manu enumerations like the following: </simpleType> <simpleType name="FOOENUMERATION"> <restriction base="xsd:string"> <enumeration value="ALPHA"><!-- enum const = 0 --> <enumeration value="BETA"/><!-- enum const = 1 --> <enumeration value="GAMMA"/><!-- enum const = 2 --> <enumeration value="DELTA"/><!-- enum const = 3 --> </restriction> </simpleType> In my client I am receiving sequences which contain elements of these various enumeration types. My need is that given a member variable, I need to know all possible enumeration values. Basically I need a function which takes an instance of one of these enums and returns a list of strings which are all the possible values. When I have an instance, running: print type(foo.enumInstance) I get: <class 'suds.sax.text.Text'> I'm not sure how to get the actual simpleType name from this, and then get the possible values from that short of parsing the WSDL myself.

• How to make Fluent NHibernate ignore Dictionary properties

  - by Matt Winckler

  I'm trying to make Fluent NHibernate's automapping ignore a Dictionary property on one of my classes, but Fluent is ignoring me instead. Ignoring other types of properties seems to work fine, but even after following the documentation and adding an override for the Dictionary, I still get the following exception when BuildSessionFactory is called: The type or method has 2 generic parameter(s), but 1 generic argument(s) were provided. A generic argument must be provided for each generic parameter. I've tried overriding by property name: .Override<MyClass>(map => { map.IgnoreProperty(x => x.MyDictionaryProperty); }) and also tried implementing ignores using a custom attribute, both of which result in the same exception from BuildSessionFactory. The only thing so far that makes this exception go away is removing the Dictionary property entirely. My question seems to be identical to this one which was never answered (though I'll expand the scope by stating it doesn't matter whether the dictionary is on an abstract base class; the problem always happens for me regardless of what class the property is on). Any takers this time around?

• Vertical-Align: A Full Explanation

  - by Livvy Jeffs

  I've been struggling with vertical alignments, a seemingly simple enough process that has a lot of idiosyncrasies throughout different languages and element types. I've done a lot of reading through stackexchange and can't seem to find a common thread of understanding. Here are the rules that I have been able to gather: 1) Vertical-align does not work in <\div>s, you have to set div {display: table-cell; vertical-align: middle} This seems like a big hassle, especially since table-cells override the height limitation even when overflow is set to hidden and expands to fit content, which means the vertical "center" is variable. I just read some source-code from Pinterest where button {vertical-align: middle}, but no other vertical-align commands seem to work. It seems as if button is by default aligned in the middle. Can someone provide a clear explanation for the vertical-align attribute? What html elements respond to vertical-align? Which html elements have default vertical-align attributes? Which html elements have non-overridable vertical-align attributes? And any clues as to understanding the idiosyncracies would help as well! Thanks in advance!

• Python with Wiimote using pywiiuse module

  - by Anon

  After seeing the abilities and hackibility of wiimotes I really want to use it in my 'Intro to programming' final. Everyone must make a python program and present it to the class. I want to make a game with pygame incorporating a wiimote. I found pywiiuse which is a very basic wrapper for the wiiuse library using c types. I can NOT get anything beyond LEDs and vibrating to work. Buttons, IR, motion sensing, nothing. I've tried different versions of wiiuse, pywiiuse, even python. I can't even get the examples that came with it to run. Here's the code I made as a simple test. I copied some of the example C++ code. from pywiiuse import * from time import sleep #Init wiimotes = wiiuse_init() #Find and start the wiimote found = wiiuse_find(wiimotes,1,5) #Make the variable wiimote to the first wiimote init() found wiimote = wiimotes.contents #Set Leds wiiuse_set_leds(wiimote,WIIMOTE_LED_1) #Rumble for 1 second wiiuse_rumble(wiimote,1) sleep(1) wiiuse_rumble(wiimote,0) #Turn motion sensing on(supposedly) wiiuse_motion_sensing(wiimote,1) while 1: #Poll the wiimotes to get the status like pitch or roll if(wiiuse_poll(wiimote,1)): print 'EVENT' And here's the output when I run it. wiiuse version 0.9 wiiuse api version 8 [INFO] Found wiimote [assigned wiimote id 1]. EVENT EVENT Traceback (most recent call last): File "C:\Documents and Settings\Nick\Desktop\wiimotetext.py", line 26, in <mod ule> if(wiiuse_poll(wiimote,1)): WindowsError: exception: access violation reading 0x00000004 It seems each time I run it, it prints out EVENT 2-5 times until the trace back. I have no clue what to do at this point, I've been trying for the past two days to get it working. Thanks!

• Wrong Ruby Float and BigDecimal subtraction result

  - by SamChandra

  I am running: [~/ruby/rails/sas]$ ruby --version ruby 1.8.7 (2009-06-08 patchlevel 173) [universal-darwin10.0] on Mac Snow Leopard 10.6.3 Can anyone help to explain why the Float and BigDecimal subtraction can be this wrong. [~/ruby/rails/sas]$ console Loading development environment (Rails 2.1.1) >> num = 30.0 => 30.0 >> num.class => Float >> ex = 28.04.to_d => #<BigDecimal:105367e40,'0.284E2',8(8)> >> ex.class => BigDecimal >> num - ex => 1.6 >> _.class => Float >> I was hoping that the result should be 1.96, I know that perhaps doing an arithmetic operation using 2 different data types are not recommended, but this behavior is so strange. It seems to be wise that from now on, I have to check the variables data type before doing any arithmetic operation. Hopefully somebody can give me an insight on what was happening.

• Mode specific key bindings

  - by rejeep

  Hey, I have a minor mode that also comes with a global mode. The mode have some key bindings and I want the user to have the posibility to specify what bindings should work for each mode. (my-minor-mode-bindings-for-mode 'some-mode '(key1 key2 ...)) (my-minor-mode-bindings-for-mode 'some-other-mode '(key3 key4 ...)) So I need some kind of mode/buffer-local key map. Buffer local is a bit problematic since the user can change the major mode. I have tried some solutions of which neither works any good. Bind all possible keys always and when the user types the key, check if the key should be active in that mode. Execute action if true, otherwise fall back. Like the previous case only that no keys are bound. Instead I use a pre command hook and check if the key pressed should do anything. For each buffer update (whatever that means), run a function that first clears the key map and then updates it with the bindings for that particular mode. I have tried these approaches and I found problems with all of them. Do you know of any good way to solve this? Thanks!
