63,903,647 | 1 | 63,905,434 | I'm reworking and extending an existing data model where a section covers person data. The current person table is just 1 big table containing all fields, both for natural and legal persons and the non-relevant fields just remain empty.
As we're adding more and more fields, the idea would be to have a single PERSON table and 2 subclasses NATURALPERSON and LEGALPERSON, where a person could never be both at the same time.
Sounds easy enough but started reading and doubting my initial approach. What would you do?
1. First option I had in mind was to have a single column in the PERSON table for the Foreign key, LEGAL_NATURAL, which would be a pointer to either LEGALPERSON or NATURALPERSON. To ensure mutually exclusiveness the record ID's for the subclasses could be constructed using a single sequence.
<IMAGE>
'''
SELECT *
FROM PRSN pr
left join LEGALPERSON_DETAIL lp on pr.legal_natural = lp.id
left join NATURALPERSON_DETAIL np on pr.legal_natural = np.id;
'''
1. Instead of the 1 column for 2 FK's, an alternative would be to have 2 columns in the PERSON table (e.g. NATURALPERSON, LEGALPERSON), each with a possible pointer to a subclass. A constraint could then make sure both aren't filled at the same time. Could make the FK relationship more obvious.
2. Different approach would be to have the subclasses point to the PERSON table. Has the disadvantage that in the PERSON table it's not visible whether it's a natural or legal person record but might be a nicer design overall.
Found some info on exclusive arcs on <URL>.
Is there a clear winner here? | The design of your three tables looks good.
AS far as PKs and FKs are concerned I recommend a technique called Shared Primary Key.
The person table has an ID field which functions as a PK.
The natural person and legal person tables do not have an independent ID field. Instead, both subclasses use PersonID as the PK in their own table. PersonID is also an FK that references ID in the person table.
This makes joins simple, easy, and fast. | |

I don't have much control over table definitions since this is an already existing database that I'm working with.
1. Create a new ASP.NET MVC 5 project (called WebApplication1 in my case)
2. Add MySQL DLLs: MySql.Data, MySql.Data.Entity.EF6, MySQL.Web.
3. Replace the existing EntityFramework tag (in Web.Config) with the following: <entityFramework> <defaultConnectionFactory type="MySql.Data.Entity.MySqlConnectionFactory, MySql.Data.Entity.EF6" /> <providers> <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6" /> </providers> </entityFramework>
4. Rebuild the project.
5. Create a folder to import all the models and create the DbContext, in my case the folder is MySQLModels
6. Add an ADO.NET Entity Data Model to the project. Select the correct database connection. Select the tables and click finish.
7. Rebuild the project.
8. Right-click on Controllers folder, then Add->Controller. In the popup window select MVC 5 Controller with views, using Entity Framework and click Add.
9. Select one of the models, select your Data context class, enter the appropriate controller name and click Add.
10. Following this process you will see the error.
There isn't much that I could find out there in relation with this error in general but specifically to do with MySQL.
There is an unanswered question, which does not have a lot of details, that can be found here: <URL>
1. I tried the suggestion here: Unable to Retrieve Metadata which suggested that I change providerName in my connection string to System.Data.SqlClient but this results in the same error.
2. I uninstalled and reinstalled everything from MySQL but to no avail.
3. UPDATE: Adding separate ADO.NET Entity Data Models for each table fixes this error. This isn't exactly the solution but absent any other solution that allows me to create scaffolding with one Db Context, this may work.
4. UPDATE 2: Tried the migration tool from Microsoft: http://www.microsoft.com/en-us/download/details.aspx?id=42657. This works, however, a lot of the data is not ported over. Again, this is a last ditch effort. Still not the solution.
I'll keep updating this question to add more details as I try various thingamajigs. | This is old, but still if someone is trying to find a fix, here it is.
The Annotations which specify the datatype, are the culprits.
Try removing the annotations from model. In this case below two
[Column(TypeName = "text")], [Column(TypeName = "date")]
And build, clean, build the project
Now the Add Controller (Scaffolding) works like charm.
Later you can re-add the same. | |

Regards: | In order to do this you probably want to make the Income and Expenses into separate sub-queries.
I have taken the two parts of your union query and separated them into sub-queries, one called income and one called expense. Both sub-queries summarise the data over the month period as before, but now you can use a JOIN on the Months to allow the data from each sub-query to be connected. Note: I have used an OUTER JOIN, because this will still join month where there is no income, but there is expense and vice versa. This will require some manipulation, because you probably are better off returning a set of zeros for the month if no transaction occur.
In the top level SELECT, replace the use of *, with the correct listing of fields required. I simply used this to show that each field can be reused from the sub-query in the outer query, by referring to the alias as the table name.
'''

There are still many calculations that you will have to insert, to get your final result, which you will have to work on separately. The resulting query to perform what you expect above will likely be a lot longer than this, I am just trying to show you the structure.
However the final tricky part for you is going to be the BBF. Balance Bought Forward. SQL is great a joining tables and columns, but each row is treated and handled separately, it does not read and value from the previous row within a query and allow you to manipulate that value in the next row. To do this you need another sub-query to SUM() all the changes from a point in time up until the start of the month. Financial products normally store Balance at points in time, because it is possible that not all transaction are accurately recorded and there needs to be a mechanism to adjust the Balance. Using this theory, you you need to write your sub-query to summarise all changes since the previous Balance.
IMO Financial applications are inherently complex, so the solution is going to take some time to mould into the right one.
Final Word: I am not familiar with OracleReports, but there may be something in there which will assist with maintaining the BBF. | |

These filters should be declare before the one you define for the user. These rules will match before the one that apply to the filter and your problem should be solved.
.
Regarding your comment: .
I think that is not correct, I mean, the filter is not the one that is adding "user" to the filter. I think the problem is how you are importing your resources.
Probably, you are doing something like this:
'''
<script type="text/javascript" language="javascript" src="resources/js/lang.js"></script>
'''
In this example, see how the relative URI doesn't not content your application context and starts with no slash. When you use a URL like that the browser is going to look for the resource in a path relative to actual path. If you have in your browser 'http://localhost:8080/roqlet/user' the result will be 'http://localhost:8080/roqket/user/theResource' (assuming 'roqket' is your app context).
So, you should do this:
'''
<c:set var="ctx" value="${pageContext.request.contextPath}"/>
<script type="text/javascript" language="javascript" src="${ctx}/resources/js/lang.js"></script>
'''
Now, that you indicate the context, the URI will be built relative to it and not to the actual: 'http://localhost:8080/roqket/theResource'

12,819,188 | 1 | 19,242,236 | The OpenGL ES Programming guide discusses that you should avoid misaligned vertex data and gives an example of aligning the data to 4 byte blocks.
<URL>
<IMAGE>
However in most demo material and tutorials I've found online I don't see anyone doing this. Example below is from a demo project on 71 Squared:
'''
static const SSTexturedVertexData3D EnemyFighterVertexData[] = {
{/*v:*/{1.987003, -0.692074, -1.720503}, /*n:*/{0.946379, -0.165685, -0.277261}, /*t:*/{0.972816, 0.024320}},
'''
And how would you do it anyway? Add a dummy 0.0 to the v and n and 2 of them to the t?
My guess is that if you're only loading the vertex data once per app it wouldn't matter much but if your binding and rebinding to different arrays on each rendered frame it would matter. My plan is to combine all my arrays into one anyway, but I'm curious. | General a vertex is made up of 'floats' which are going to be aligned, so you don't need to get too concerned with that. In fact a lot of books use ordinary 'struct's to hold vertex data, which are not guaranteed to be contiguous due to the padding issue, but if all you have are floats, that's fine since you aren't likely to have padding. Of course, some people (myself included) prefer to use the STL 'vector' from C++ but if you are on iOS, while you can use C++ you are probably using Objective-C thus contiguity in a non-struct way would involve normal C arrays which are not so fun to work with.
If you create custom structures to hold vertex data as well as other data for your drawable object, and you use 'short's or other types, you might find padding to become an issue. But if you stick with only 'float's you will be fine, and you will be in good company since most educational sources on OpenGL do this. | |

29,110,288 | 1 | 29,110,756 | How can <URL>?
I mean the chart similar to what Audacity generates:
<IMAGE>
I know that I can get the FFT data for given time 't' (when I play the audio) with:
'''
float fft[1024];
BASS_ChannelGetData(chan, fft, BASS_DATA_FFT2048); // get the FFT data
'''
That way I get 1024 values in array for each time 't'. Am I right that the values in that array are signal amplitudes ('dB')? If so, how the frequency ('Hz') is associated with those values? By the index?
I am an programmer, but I am not experienced with audio processing at all. So I don't know what to do, with the data I have, to plot the needed spectrum.
I am working with C++ version, but examples in other languages are just fine (I can convert them). | From the documentation, that flag will cause the FFT magnitude to be computed, and from the sounds of it, it is the linear magnitude.
'''
dB = 10 * log10(intensity);
dB = 20 * log10(pressure);
'''
(I'm not sure whether audio file samples are a measurement of intensity or pressure. What's a microphone output linearly related to?)
Also, it indicates the length of the input and the length of the FFT match, but half the FFT (corresponding to negative frequencies) is discarded. Therefore the highest FFT frequency will be one-half the sampling frequency. This occurs at N/2. The docs actually say
> For example, with a 2048 sample FFT, there will be 1024 floating-point values returned. If the BASS_DATA_FIXED flag is used, then the FFT values will be in 8.24 fixed-point form rather than floating-point. Each value, or "bin", ranges from 0 to 1 (can actually go higher if the sample data is floating-point and not clipped).
That seems pretty clear. | |
13,522,327 | 1 | 13,527,092 | It appears this happens with any blendmode - not just erase
I've been working on a crude lighting engine for a game of mine in Adobe AIR, written in pure AS3. How it works is there is a bitmap data the size of the screen, and at the beginning of each frame it is set to a black transparent rectangle. During that step, things can subtract from the bitmap data and then when it is drawn on the screen those areas will appear lighter.
Setting that up and everything has gone smoothly. Currently I'm messing around with a basic radial gradient from the light source, and setting that up was pretty easy
'''
_circ.graphics.lineStyle();
_circ.graphics.beginGradientFill(GradientType.RADIAL, [0x000000, 0x000000], [.9, 0], [0, 255]);
_circ.graphics.drawCircle(0, 0, 100);
_circ.graphics.endFill()
'''
Then to draw (well, anti-draw) it onto the bitmap data, I just do this
'''
FP.matrix.identity();
FP.matrix.tx = x + 30;
FP.matrix.ty = y + 5;
WorldGame.darkBit.draw(_circ, FP.matrix, null, BlendMode.ERASE, null, true);
FP.matrix.identity();
'''
'FP.matrix' is just a generic global matrix (I'm using Flashpunk). Now this ALMOST works, except for one tiny problem.
<IMAGE>
If you look very closely you'll be able to see a very thin black line going around the gradient, which is so very frustrating. I have no idea what's causing it - I've tried making the gradient smaller than the circle, I've tried making it linear, tried making it a different colour. It doesn't happen on blend modes other than 'ERASE' as well, and as far as I can tell, it doesn't happen to non-gradients either (still erasing).
Any suggestions? | <URL>
Somehow I missed this in my earlier searching, guess I didn't use the right keywords. The solution is just to set bitmap caching to true on the sprite that is being used as the "eraser". For example:
'''
_circ.cacheAsBitmap = true;
'''

20,906,641 | 1 | 21,142,457 | I am trying to query a graph to return all of the paths with a specified relationship.
I am building a family tree and I have the following nodes:
1. Person
2. Edge
The relationships which connect two people are:
1. PARENT
2. CHILD
3. COUPLE
So an example of some data are:
1. a:Person<-[:CHILD]-(Edge)-[:PARENT]->b:Person
2. a:Person<-[:COUPLE]-(r2:Edge)-[:COUPLE]->c:Person<-[:PARENT]-(r3:Edge)-[:CHILD]->d:Person
In my query I would like to be able to draw the graph in my front end so I need to get every Person and Edge Node, and every relationship between them, that is connected to my starting person.
I tried originally to use allShortestPaths to reduce the duplication of nodes but this misses a lot of relationships (e.g. if parents have multiple children then only either the mother or father relationship to a child will be returned and not both). My current cypher is as follows (I distinguish between Edge and Person nodes by filtering on the type property which only exists on Relationships):
'''
START person = node({personId})
MATCH person-[:PARENT | CHILD | COUPLE*]-(relatedPeople:Person)
WITH relatedPeople, person
MATCH p = allShortestPaths(person-[:PARENT|CHILD|COUPLE]-(relatedPeople))
WITH [n in nodes(p) WHERE not(has(n.type))] AS people, last([n in nodes(p) WHERE has(n.type) | id(n)]) AS relationship, [r in rels(p) | TYPE(r)] AS rels
WITH relationship, rels, last(people) AS destination, [p in people | id(p)] AS source
MATCH destination-[:NAME]->(name), destination-[:GENDER]->gender
RETURN source, id(destination), relationship, rels, collect(name), gender
'''
I thought this was working but realised that the shortest path drops some relationships. I was thinking of just finding all related nodes and all of the relationships and then processing the results to construct the correct format but I feel there is probably an easier /more efficient way.
I have tried returning all paths but the model can have loops and therefore the number of paths returned increases exponentially with size. The cypher below creates a sample data set.
'''
CREATE (p1:Person)<-[:CHILD]-(r1:Edge { type:'parentChild' })-[:PARENT]->(p2:Person)
<-[:COUPLE]-(r2:Edge { type:'couple' })-[:COUPLE]->(p3:Person)<-[:PARENT]-
(r3:Edge { type:'parentChild' })-[:CHILD]->p1<-[:COUPLE]-(r4:Edge { type:'couple' })-[:COUPLE]->
(p4:Person)<-[:CHILD]-(r5:Edge { type:'parentChild' })-[:PARENT]->(p5:Person)<-[:COUPLE]-
(r6:Edge { type:'couple' })-[:COUPLE]->(p6:Person)<-[:PARENT]-(r7:Edge { type:'parentChild' })-
[:CHILD]->p4,
p5<-[:PARENT]-(r8:Edge { type:'parentChild' })-[:CHILD]->(p7:Person),
p5<-[:PARENT]-(r9:Edge { type:'parentChild' })-[:CHILD]->(p8:Person),
p5<-[:PARENT]-(r10:Edge { type:'parentChild' })-[:CHILD]->(p9:Person)
'''
The image shows the view of the data. <IMAGE>
The desired result is a row for every Node-Edge-Node connection. There are 10 in total in this data but I get 128 rows when I return all paths due to the loops. Is there a more efficient method of filtering the paths? | In order to resolve this I used the following cypher.
'''
START person = node({personId})' +
MATCH person-[:PARENT | CHILD | COUPLE*0..]-(p:Person)
WITH distinct p
MATCH p-[r]-(edge:Edge), p-[:NAME]->(name), p-[:GENDER]->gender, edge-[:FACT]->(fact)
RETURN p, id(p), collect(name), gender, type(r), id(edge), collect(fact.type)
ORDER BY id(edge)
'''
I used to in the relationship to match all of the "Person" nodes who are connected, including the original node. After removing the duplicates it was simply a case of finding all of the relationships between the nodes and the extra information on each point.
This cypher returned a row for every "person" to "edge" relationships. There is some duplication in "person" information but this was easily parsed out once the data was returned.

UPDATE
---
Here's db schema. it's generated by NH.<IMAGE> | There are two ways of ensuring your collected is persisted.
1. Call session.Flush(); after session.Save(one);. This will cause NHibernate to persist your collection. More information on flush can be found here.
2. Wrap the whole thing in a transaction, i.e. using (var session = factory.OpenSession())
using (var transaction = session.BeginTransaction())
{
var one = new SomeOne();
one.Foo.Add("Dato");
one.Foo.Add("Mari");
session.Save(one);
transaction.Commit();
}
There are several reasons why option two is better than option one. The main advantage is that all objects are saved back to the DB within the same transaction, so if one insert fails then the transaction is rolled back and your DB is not left in an inconsistent state. The acceped answer to this <URL> has an extensive explanation of why you should use transactions with NHibernate. | |

This doesn't concern the actual question, but for those who need to retrieve the entire network adapter IPv6 configuration, the 'IPInterfaceProperties.GatewayAdresses' property only supports the IPv4 gateways. As mentionned in the answer comments below, the only way to get the entire info until .NET framework 4.5 is to call WMI. | You can do so using Win32_NetworkAdapterConfiguration. You might have overlooked it.
IPSubnet will return an array of strings. Use the second value.

I hope to add a admob view at the top or bottom of an 'UITableView'.
In Interface Builder it is easy -- just drag the view to the top or bottom of the 'UITableView'.
But I would like to add view to the top or bottom of the table dynamically using code. | You can add header or footer views to a 'UITableView' by implementing the following 'UITableViewDelegate' methods in your 'UITableViewController':

- (CGFloat)tableView:(UITableView *)tableView
heightForHeaderInSection:(NSInteger)section
{
CGFloat height = 100.0; // this should be the height of your admob view
return height;
}
- (UIView *)tableView:(UITableView *)tableView

{
UIView *headerView = myAdMobView; // init your view or reference your admob view

72,398,975 | 1 | 72,406,229 | I'm taking a cell that people can enter data into, and trying to interpret it in several ways. They can enter a code with between 7 and 20 characters. Depending upon the length, and the leading character, I want it to strip out the excess data and leave just a serial #.
The different possibilities of data that people can enter are as follows:
'''
7 character serial #
8 character serial #
8 character serial # with leading L
9 character serial # with leading D or L
10 character serial #
11 character serial # with leading M
12 character serial #
13 character serial # with leading M
20 character serial # with 12 leading useless characters
'''
I've managed to create multiple IF statements that individually can identify each of these, but I'm trying to combine them into a single formula so that one cell shows JUST a valid serial #, after editing the entered data from a separate cell.
I've managed to mix a couple of them, but the more AND and/or OR statements I add, the more confusing, and more likely to break the formula gets.
Is there an easier/better way to do this?
As an addendum, thanks to Special Instance:
<IMAGE>
I have removed the attempted formulae above, and recreated 4 formulae, posted below, which does each of the above necessary steps, but they're separate, and I need them together:
'''
=IF(AND(LEN(A2)=8,(LEFT(A2,1)="L")), RIGHT(A2,7),A2)

=IF(OR(LEN(A2)=11,LEN(A2)=13),RIGHT(A2,LEN(A2)-1),A2)
=IF(NOT(LEN(A2)=20),A2,RIGHT(A2,8))
''' | The formula below consolidates your logic into 3 possibilities
'''
=IF(SUM(N(LEN(A1)={7,10,12})),A1,
IF(SUM(COUNTIF(A1,"L???????"),COUNTIF(A1,{"L","D"}&"????????"),COUNTIF(A1,"M??????????"&{"","??"})),REPLACE(A1,1,1,""),
IF(SUM(N(LEN(A1)={8,20})),RIGHT(A1,8),"ERROR")))

1. where the input entered is valid
2. where the input requires the 1st character to be eliminated
3. where only the last 8 characters of the input are valid

(due to the employment of array constants, this will have to be entered as an <URL>
but this answer is purely a function of your sample which, because serial numbers are usually alphanumeric in type, I don't think is realistic, e.g. the logic involves removing leading 'L', 'D' or 'M' characters, but your data indicate that these 3 same characters occur in the reformatted data - if the reality is that such characters are never valid then the logic could be simplified by the use of a series of 'SUBSTITUTE()' functions. | |

You are bound to encounter 'java.lang.OutOfMemoryError: GC overhead limit exceeded'.
This happens when JVM realizes that it is spending too much time in 'Grabage Collection'. By default the JVM is configured to throw this error if you are spending 'more than 98% of the total time' in 'GC' and after the 'GC' 'less than 2%' of the 'heap' is recovered.
In this particular case you are creating 'new instance' of 'List' for every iteration, ( 'immutability', so each time a 'new instance' of 'List' is returned ). Which means each iteration leaves an useless instance of 'List', and for 'List' with size in millions, it will take lot of memory and trigger 'GC' very frequently. Also, each time 'GC' has to free lot of memory hence take lot of time.
This ultimately leads to error - 'java.lang.OutOfMemoryError: GC overhead limit exceeded'.
-> This means that the little amount GC was able to clean will be quickly filled again thus forcing GC to restart the cleaning process again.This forms a vicious cycle where the CPU is 100% busy with GC and no actual work can be done. The application will face extreme slowdowns - operations which used to be completed in milliseconds will now likely to take minutes to finish.
This is a pre-emptive fail-fast safeguard implemented in JVM's.
You can disable this safeguard by using following Java Option.
'''
-XX:-UseGCOverheadLimit
'''
But I will strongly recommend doing this.
And even if you disable this feature ( or if your Spark-Cluster avoids this 'to some extent' by allocating large heap space ), some thing like
'''
(1 to <PHONE> ).toList
'''
will take a long long time.
Also, I have a strong feeling that systems like 'Spark' which are supposed to be running multiple jobs are configured ( by default, may be you can override ) to 'pause' or 'reject' such jobs as soon as they realize extreme GC which can lead to starvation of other jobs. And this may be the main reason your job is always loading.
You can get a lot of relief by using a 'mutable List' and appending values to it with a for loop. Now you can parallelise your mutable list.
'''
val mutableList = scala.collection.mutable.MutableList.empty[ Int ]
for ( i <- 1 to <PHONE> ) {
mutableList.append( i )
}
val l = sc.parallelize( mutableList )
'''
But even this will lead to multiple ( but many times less severe ) memeory allocations( hence GC exectuions ) whenever the 'List' is 'half-full', which result in 'memory relocation' of whole 'List' with double of previously allocated memory. | |

I'm new to the world of STM32 and STM32CubeIDE so any help/explanation is greatly appreciated. Thank you | The functions are grayed out because a preprocessor directive is not met and therefore these functions are discarded during compile time.
If you look in the file you will find something like these at the very beginning:
'#ifdef HAL_TIM_MODULE_ENABLED'
The STM32 HAL is designed to be able to enable or disable several modules explicitly.
And these definitions are located in the 'stm32l4xx_hal_conf.h' file.
Just open this file and find the 'HAL_TIM_MODULE_ENABLED' definition and remove the surrounding comment block.
Moreover the config file is autogenerated in the CubeIDE depend on the selected "Pin & Configuration" settings (ioc file). Also check these to enabled the timer module. | |

Thanks a lot.
The image:
<IMAGE> | The reason why you are getting different results is the fact that your colour segmentation algorithm uses <URL>. I'm going to assume you don't know what this is as someone familiar in how it works would instantly tell you that this is why you're getting different results every time. In fact, the different results you are getting after you run this code each time are a natural consequence to -means clustering, and I'll explain why.
How it works is that for some data that you have, you want to group them into groups. You initially choose random points in your data, and these will have labels from '1,2,...,k'. These are what we call the . Then, you determine how close the rest of the data are to each of these points. You then group those points so that whichever points are closest to any of these points, you assign those points to belong to that particular group ('1,2,...,k'). After, for all of the points for each group, you update the , which actually is defined as the representative point for each group. For each group, you compute the average of all of the points in each of the groups. These become the centroids for the next iteration. In the next iteration, you determine how close each point in your data is to . You keep iterating and repeating this behaviour until the centroids don't move anymore, or they move very little.
How this applies to the above code is that you are taking the image and you want to represent the image using only possible colours. Each of these possible colours would thus be a centroid. Once you find which cluster each pixel belongs to, you would replace the pixel's colour with the centroid of the cluster that pixel belongs to. Therefore, for each colour pixel in your image, you want to decide which out of the possible colours this pixel would be best represented with. The reason why this is a colour segmentation is because you are the image to belong to only possible colours. This, in a more general sense, is what is called .
Now, back to -means. How you choose the initial centroids is the reason why you are getting different results. You are calling -means in the default way, which automatically determines which initial points the algorithm will choose from. Because of this, you are to generate the same initial points each time you call the algorithm. If you want to the same segmentation no matter how many times you call 'kmeans', you will need to . As such, you would need to modify the -means call so that it looks like this:
'''
[cluster_idx, cluster_center] = kmeans(ab,nColors,'distance','sqEuclidean', ...
'Replicates', 3, 'start', seeds);
'''
Note that the call is the same, but we have added two additional parameters to the -means call. The flag 'start' means that you are specifying the initial points, and 'seeds' is a 'k x p' array where is how many groups you want. In this case, this is the same as 'nColors', which is 3. 'p' is the dimension of your data. Because of the way you are transforming and reshaping your data, this is going to be 2. As such, you are ultimately specifying a '3 x 2' matrix. However, you have a 'Replicate' flag there. This means that the -means algorithm will run a certain number of times specified by you, and it will output the segmentation that has the least amount of error. As such, we will repeat the 'kmeans' calls for as many times as specified with this flag. The above structure of 'seeds' will no longer be 'k x p' but 'k x p x n', where 'n' is the number of times you want to run the segmentation. This is now a 3D matrix, where each 2D slice determines the initial points for each run of the algorithm. Keep this in mind for later.
How you choose these points is up to you. However, if you want to randomly choose these and not leave it up to you, but want to reproduce the same results every time you call this function, you should set the <URL> to be a known number, like '123'. That way, when you generate random points, it will always generate the same sequence of points, and is thus reproducible. Therefore, I would add this to your code before calling 'kmeans'.
'''
rng(123); %// Set seed for reproducibility
numReplicates = 3;
ind = randperm(size(ab,1), numReplicates*nColors); %// Randomly choose nColors colours from data
%// We are also repeating the experiment numReplicates times
%// Make a 3D matrix where each slice denotes the initial centres for each iteration
seeds = permute(reshape(ab(ind,:).', [2 nColors numReplicates]), [2 1 3]);
%// Now call kmeans
[cluster_idx, cluster_center] = kmeans(ab,nColors,'distance','sqEuclidean', ...
'Replicates', numReplicates, 'start', seeds);
'''
Bear in mind that you specified the 'Replicates' flag, and we want to repeat this algorithm a certain number of times. This is '3'. Therefore, what we need to do is specify initial points for . Because we are going to have 3 clusters of points, and we are going to run this algorithm 3 times, we need 9 initial points (or 'nColors * numReplicates') in total. Each set of initial points has to be a in a 3D array, which is why you see that complicated statement just before the 'kmeans' call.
I made the number of replicates as a variable so that you can change this and to your heart's content and it'll still work. The complicated statement with <URL> allows us to create this 3D matrix of points very easily.
Bear in mind that the call to <URL> in MATLAB only accepted the second parameter as of recently. If the above call to 'randperm' doesn't work, do this instead:
'''
rng(123); %// Set seed for reproducibility
numReplicates = 3;
ind = randperm(size(ab,1)); %// Randomly choose nColors colours from data
ind = ind(1:numReplicates*nColors); %// We are also repeating the experiment numReplicates times
%// Make a 3D matrix where each slice denotes the initial centres for each iteration
seeds = permute(reshape(ab(ind,:).', [2 nColors numReplicates]), [2 1 3]);
%// Now call kmeans
[cluster_idx, cluster_center] = kmeans(ab,nColors,'distance','sqEuclidean', ...
'Replicates', numReplicates, 'start', seeds);
'''
---
Now with the above code, you should be able to generate the same colour segmentation results every time.

Thank you for helping me :) I hate to lose too much time with styles :'( | Make sure you are importing your CSS file correctly...
If so, change your button to something like this.
'''
<Button
className="buttonW"
component={Link}
color="success"
size="lg"
to="/album-carousel-page"
>
Galeria
</Button>
'''
Then in your CSS, prefix a period "." before the class name
'''
.buttonW {
width: "100px",
height: "30px"}
'''
..
this should work for you..
If all fails, you can then use inline styling as shown below.
'''
<Button
className="buttonW"
style={{height: '30px', width : '100px'}}
component={Link}
color="success"
size="lg"
to="/album-carousel-page"

Good luck! | |
66,990,694 | 1 | 66,992,019 | I am trying to control a stepper motor, using a A4988 driver along with a Nucleo 144 board with an STM32F767ZI on it.
The A4988 driver expects a single rise in voltage to HIGH in order to step the motor.
Having made some voltage readings using a multimeter, I have found that during and even while the program is paused, there is a steady voltage of around 1.2V being output by the pin.
I also added some lines to toggle an LED (built onto the board) whenever the output to the A4988 driver is toggled between HIGH and LOW, which works fine.
Here is the code:
main.c
'''
#include "./headers/stm32f767xx.h"
#include <stdint.h>
int main(void)
{
initMotor(0);
initLed(0);
uint32_t a = 0;
while (1)
{
if (a >= 300000)
{
toggleLed(0);
stepMotor(0);
a = 0;
}
a++;
}
}
'''
./drivers/motor.c
'''
#include "../headers/stm32f767xx.h"
void initMotor(int step_pin)
{
RCC->AHB1ENR |= RCC_AHB1ENR_GPIOGEN; // enable GPIOG clock
GPIOG->MODER &= ~(0b11 << (step_pin * 2)); // clear bits
GPIOG->MODER |= (0b01 << (step_pin * 2)); // set mode to OUTPUT
GPIOG->OTYPER &= ~(0b1 << step_pin); // set output type to PUSH-PULL
GPIOG->PUPDR |= (0b10 << (step_pin * 2)); // pull the pin down
GPIOG->ODR &= ~(0b1 << step_pin); // set output to LOW
}
void stepMotor(int step_pin)
{
GPIOG->ODR ^= (0b1 << step_pin); // toggle between LOW and HIGH
}
'''

I've verified, using a multimeter, that the voltage being provided to the board via an STLINK USB is 5V (which I believe is sufficient), and the driver is also receiving the correct voltage of 5V.
I do not believe this to be a problem to do with the A4988 driver. I have tried multiple of the same driver from various manufacturers, and still I get the same result. The motors are also being supplied a high enough voltage (12V) but are not drawing it all in.
I have come to the conclusion that it is most likely an issue originating from the Nucleo 144 board, but a little stuck as to what the actual issue is.
I am using GPIO G pin 0, which is labelled "IO" on the board.
Any suggestions as to what I should try next, or ideas as to what it could be, are greatly appreciated.

As requested, here is a diagram of my setup:
<IMAGE> | If you configure the output to be PUSH/PULL, adding a PULLDOWN resistor will divide the output voltage over the resistor. Do not use PU/PD resistors with PP, because it is always driven and doesn't need a PU/PD. | |
53,814,478 | 1 | 53,814,972 | I know that there is already sample programs floating around that cover this, but I need to do the towers of hanoi with 6 discs a specific way for an assignment and I'm having trouble. Code I currently have is below:
'''
s([],[],[]).
initial(s([1,2,3,4,5,6], [], [])).
goal(s([],[],[1,2,3,4,5,6])).
'''
I also have 26 lines of code to verify valid states, however I tested that code on it's own and it works, the issue I'm having is creating the code to move the discs from stack to stack. An example of what I'm trying to do along with an example query is below:
'''
changeState((s([A | B],[],[])), s([C], [D], [])) :- C is B, D is A.
?- changeState((s([1,2,3,4,5,6],[],[])), s([2,3,4,5,6], [1], [])).
'''
So this would be the very beginning, where all 6 plates are on the first stack, and I want to move the top plate to the second stack. Essentially, I want to be able to remove the first element from a list, and add it to another list, whether it is empty or not.
Got what I needed above working, now I just need help fixing the traverse predicate. Entire code is below:
'''

I get this output: <IMAGE>
I've left it running after I get those responses for about 10 minutes and it still doesn't produce new ones so it's just continuing to run over and over again. As mentioned above, the point of the program is to solve the Towers of Hanoi problem with 6 discs using Lists. For those not familiar with Towers of Hanoi, you essentially need to move all discs from the first stack, to the last 3rd stack. You can only move 1 disc at a time, and you cannot place a larger disc on-top of a smaller disc. So you start with (s([1,2,3,4,5,6], [], [])) with each list representing Stack A, Stack B, Stack C respectively, and the goal is to end with (s([], [], [1,2,3,4,5,6])). I manually ran through an entire solution (63 moves) through the changeState predicates and all transitions were accepted, so the issue is with the transverse predicate. The transverse predicate is meant to show all steps that lead up to the solution, and all possible solutions. It's also meant to stop cycles, so that it's not just swapping the same 2 discs over and over again. Can't quite figure out what's wrong with my predicates thats causing me to get this output, I'm still fairly new to prolog, so I would appreciate any help! | You can use here instead of 'is/2' (which is typically used to evaluate expressions).
For example we can define a move from the first tower to the second tower, given the second tower is empty:
'''
changeState((s([A|T1],[], T3)), s(T1, [A], T3)).
'''
or we can move an element to the second tower that is non-empty, given the top of the stack is an element that is larger:
'''
changeState(s([A|T1], [B|T2], T3), s(T1, [A,B|T2], T3)) :-
A < B.
'''
The above will result in a total of 12 rules: 3 sources, times 2 destinations times 2 possibilities (empty destination, versus non-empty destination). This is not very elegant. We can construct a helper predicate that checks if the destination stack is valid, with:
'''
valid_stack([], _).
valid_stack([H|_], X) :-
X < H.
'''
so then we can compress the two rules above into:
'''
changeState((s([A|T1], T2, T3)), s(T1, [A|T2], T3)) :-
valid_stack(T2, A).
'''
This will thus result in six rules: three sources, and two destinations.
We thus no longer need to validate the moves, since if the 'changeState' succeeds, then the proposed move is possible the original state was valid.
This is not the full solution however (I leave the rest as an exercise). You will need a mechanism that enumerates over the possible moves, and makes sure that you do not end up in loops (like moving a disc constantly between two towers).
After using the 'traverse/3' predicate, we obtain a list of moves to the goal:

17,264,395 | 1 | 17,265,120 | I'm trying to make a CSS menu with submenus. When I move the mouse over a child element of list, I want the submenu to appear inside that child if there is any.
<IMAGE>
As it is avaliable to see above, sub menu appears but I don't want that to happen when I move the cursor over the areas that I've marked with circles. These are padding areas.
Here's my markup:
'''
<ul>
<li><a href="/home">Home</a></li>
<li><a href="#">About Us</a>
<ul>
<li><a href="/mission">Our Mission</a></li>
<li><a href="/vision">Our Vision</a></li>
</ul>
</li>
</ul>
'''
And this is the CSS:
'''
a { color: #000; text-decoration: none; }
a:hover { color: #A0A0A0; }
ul > li { float: left; padding: 0px 30px; list-style-type: none;
margin: 0px 5px; background-color: #CACACA; }
ul > li:hover > ul { display: inline; }
ul > li > ul { position: fixed; display: none; }
'''
Now there is no problem with this code. As you can see in <URL>, it works as I wanted, the submenu appears when I move the mouse over the "About Us" menu.
However, my problem here is that there are blank spaces(padding) inside menu items and the submenu appears even if I hover over these spaces. But I want the submenu to appear only when I hover the '<a>' element inside the '<li>'.
To accomplish this, I tried that code:
'''
ul > li > a:hover > ul { display: inline; }
'''
instead of the existing:
'''
ul > li:hover > ul { display: inline; }
'''
but it didn't work, I wasn't expecting since the '<a>' and '<ul>' are the children of the very same '<li>' element.
I'm creating a template for a CMS, so I don't want to get involved with jQuery implementations too much, like setting 'id's or 'class'es for list elements. I want to make an implementation with pure CSS.
And I will be using seperating images between list elements, so I must use 'padding' instead of 'margin'.
If I was using 'margin', it would be easy since the 'width' of the list element would be same with the '<a>' element's 'width'.
But here, after all these exceptions, I need some help. Any ideas are highly appreciated.
Thanks in advance. | This is possible, but only-just, and with some fairly severe caveats; first the CSS to hide/show the sub-menu:
'''
ul > li > ul {
position: fixed;
opacity: 0;
-moz-transition: opacity 1s linear;
-ms-transition: opacity 1s linear;
-o-transition: opacity 1s linear;
-webkit-transition: opacity 1s linear;
transition: opacity 1s linear;
}
ul > li a:hover + ul,
ul > li:hover a + ul:hover{
opacity: 1;
-moz-transition: opacity 1s linear;
-ms-transition: opacity 1s linear;
-o-transition: opacity 1s linear;
-webkit-transition: opacity 1s linear;
transition: opacity 1s linear;
}
'''
<URL>.
Now, the caveats:
1. The display property won't animate (it can't, there's no interim states between none and inline-block (or between any other valid values for the property), so the sub-menu always has to be 'visible'/'present' on the page (albeit with an opacity of 0 hiding it in most browsers).
2. The transitions are necessary, because that's the only way that the cursor would have time to move from the a link to the ul without it immediately hiding; the transition is, basically, a time-delay to allow the second of the selectors, ul > li:hover a + ul:hover to match.
3. cross-browser compatibility is likely to be a problem, since transitions aren't supported in Internet Explorer < 10, mind you nor is opacity until version 9.
4. The major problem, though, is selector specificity. It's going to be rather difficult to write the selectors for arbitrary-depth menus using this technique. So, while it's possible, I certainly wouldn't recommend using this approach, as it seems far too prone to failure. | |

This is my method that controls the image. I have an UIImageView in the .xib file and when i run the app i see the image i have selected in attribute inspector, but it disappears when this method is called.

I have created a github repository where i cloned my project in so you can see my code.

Only difference is the location of the luminaceImageView, now it is located in the middle of the screen so i can be sure that it is in view of the device. | You say that:
> the image object is not nil but the luminanceImageView stays nil.
Of course, you need to create the image view first, before you can set its image. The easiest in your case is probably to create it and set its image in one go, and then add it to your view:
'''
self.luminanceImageView = [[UIImageView alloc] initWithImage:image];
[self.view addSubview:self.luminanceImageView];
'''
EDIT (after looking at the GitHub):
You currently set the view like this:
'''
self.luminanceImageView = [[UIImageView alloc] init];
[self.luminanceImageView setImage:image];
'''
That means that if you set it in the xib (I have not checked that), then you override it here.
There are three problems with this:
1. the luminanceImageView still needs to be added to your view, as I already stated above
2. the plain init creates an imageView with size (0, 0). This is unlike the initWithImage:, which creates a imageView with the size of the image.
3. the setImage: does not resize the imageView. From the UIWebView documentation:
> Setting the image property does not change the size of a UIImageView. Call sizeToFit to adjust the size of the view to match the image.
If you have correctly set the imageView with its size in the XIB, then leave out everything else and just do:
'''
[self.luminanceImageView setImage:image];
'''
If the size is not correct, then follow this with:
'''
[self.luminanceImageView sizeToFit];
'''
EDIT (after debugging the code):
Your problem is that you set the image from a background thread. Almost all view operation in iOS need to be done from the main thread. Doing like this solves your problem:
'''
dispatch_async(dispatch_get_main_queue(), ^{
[self.luminanceImageView setImage:image];
[self.view bringSubviewToFront:self.luminanceImageView];
});
'''
BTW, you also change self.layer in your code. That is probably not a good idea and may lead to problems later. Use a separate view for the camera, and use [cameraView.layer addSublayer:newLayer] to get around that. | |

Is it OK to use multiple inheritance if one parent class is an interface (only contains pure virtual functions with virtual destructor)?
I want to expose only interface part (yellow class in the picture) to increase compile speed. Green part is implementation part. But CPet should inherit from CAnimal(is-a relation) and IPet(implement), there are "Diamond of Death" :(
Interface classes (in yellow) only have pure virtual functions and virtual destruction, so when I create CDog, CCat through factory class, there are no problem like ambiguity. CDog has two vtables (from IDog and CPet) but in the virtual function tables, the points indicate same function (CDog member functions).
There's no compile error, no running error... but I'm worry about this hierarchy.
Is it OK or are there any problems?
PS : I don't want to use 'virtual inheritance' because if I use that, I can't look into class member variable through watch view.(I guess it is because virtual inheritance link to parent class like linked-list.)

28,166,778 | 1 | 28,193,425 | I am currently adding a SOAP-WSDL Service to my project using "Add Service Reference". it creates all necessary classes and functions for me to call. Some of these functions dont give me a response. After 1 minute delay i get a timeout exception. However when i forge the request using Postman (a chrome extension for making network requests) it gets full response. i got suspicious and started to inspect network using Wireshark. after inspection i saw that problem was at the service. but i can't make them fix that. so i need to imitate Postman request using C#.
Main difference between mine and postman is, Postman posts all necessary data in single request for a response, but my client posts just http headers waits for a Http Continue and continues sending necessary data. i guess this breaks the service.
Here are wireshark screenshots for Postman and my client
(Postman is on the left of image and right one is my .net client - sorry for my perfect paint skills)
<IMAGE>
Is there any configuration on .net wsdl client with basicHttpBinding i can configure to make single request for a call?
edit: when i further investigated my C# client i saw that .net http layer send an initial POST with saying (Expect: 100 Continue), after it receives continue it continues to send SOAP Envelope
edit2: i changed my code to issue request using HttpWebRequest, but .net still sends header and post body with seperate requests (even when i disabled Expect: 100 Continue) and in my theory this breaks service.
question2: is there anyway to say HttpWebRequest, don't split header and body? send all of them in single request?
edit3: i solved the problem. but it wasn't about 100 Continue. service was being broken because of missing User-Agent Header | i finally solved the problem. after long inspections and tries i saw that remote service stops responding in the middle of the data communication if i dont add User-Agent HTTP Header. so i added http header using IClientMessageInspector before every request

''' | I have experienced this before. My mistake was I was always modifying the output image.
Make sure that 'image' is always untouched.
All the work should be done on 'image2'.
The output should also be 'image2'
You can basically connect all your 'valueChanged()' signal to one slot 'onSliderValueChanged(value)'.
Pseudocode:
'''
function onSliderValueChanged(value)
h = get H slider value
s = get S slider value
v = get V slider value
image2 = image
for i = 0 to image2.width - 1
for j = 0 to image2.height - 1
if h != 0 and s != 0 and v != 0
// set image2 pixel color
color = QColor::fromHSV(h, s, v)
image2.setPixel(i, j, color)
'''
Every slider movement, 'image2' should always be equal to 'image' at first.
Then make the necessary pixel manipulations on image2. | |

I don't think the problem is with the findNeighbors function since I got it from <URL> stackoverflow answer. So I assume the problem is in the update function but I can't see where the logic is wrong based on the game rules. | I suspect this is the problem:
'''
cells[x][y] = update(cells,x,y)
'''
You've only got grid, which you're updating . Generation n+1 should only take account of information from generation n - whereas currently you've got a mixture of information from n and n+1. You'll end up with the values of the neighbours above and to the left of you, and the values of the neighbours to the right and below you, because they haven't been recomputed yet.
So for example, take this pattern (where # means "alive"):
'''
...
###
...
'''
That go to:
'''
.#.
.#.
.#.
'''
... but in fact, you'll end up with (I think):
'''
.##
#.#
... // Bottom-middle only has one live neighbour at computation time
'''
By the time we compute top right, it has three neighbours. The left-middle has 2 live neighbours at computation time; the centre has 4, and the right-middle has 2. Nothing on the bottom row has three neighbours by the time it's computed, so it stays dead.
Typically a Conway's Life implementation will either compute an entirely new grid for each generation, or it will flip between two grids, computing all of one from the other. | |

4,887,456 | 1 | 4,888,128 | In the application that I'm working on right now, I need to periodically check eligibility of tens of thousands of objects for some kind of a service. The decision diagram itself is in the following form, just way larger: <IMAGE>
In each of the end nodes (circles), I need to run an action (change an object's field, log information etc). I tried using Drool Expert framework, but in that case I'd need to write a long rule for every path in the diagram leading to an end node. Drools Flow doesn't seem to be built for such a use case either - I take an object and then, depending on the decisions along the way, I end up in one of the end nodes; and then again for another object. Or is it? Could you give me some examples/links to such solutions?
Drools Flow calls might look like this:
'''
// load up the knowledge base
KnowledgeBase kbase = readKnowledgeBase();
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
Map<String, Object> params = new HashMap<String, Object>();
for(int i = 0; i < 10000; i++) {
Application app = somehowGetAppById(i);
// insert app into working memory
FactHandle appHandle = ksession.insert(app);
// app variable for action nodes
params.put("app", app);
// start a new process instance
ProcessInstance instance = ksession.startProcess("com.sample.ruleflow", params);
while(true) {
if(instance.getState() == instance.STATE_COMPLETED) {
break;
}
}
// remove object from working memory
ksession.retract(appHandle);
}
'''
That is: I'd take an Application object, start a new process for it, when the process is finished (the final, action node would modify the application somehow), I'd remove the object from working memory and repeat the process for a new App object. What do you think about this solution?
I've ended up using Drools Flow and it has been working quite fine. My decision process isn't as straightforward as Drools Expert asks for and depending on where in the decision tree the process is it needs to load lists of objects from the database, transform them, make decisions, log everything etc. I use a Process object that is passed to the process as a parameter and stores all my global variables (for the process) and some convenience methods that are repeated at different points in the tree (as writing Java code in the 'Script Task' nodes isn't very convenient itself). I also ended up using Java to make decisions (and not 'mvel' or rules) - it's faster and I'd say easier to control. All objects that I work with are passed as parameters and used as normal Java variables in the code. | is definitely the way to go.
If you want to avoid repeating yourself for the higher nodes, then the trick is to use 'insertLogical' (or just 'insert' if you're in a stateless session) and to understand that rules can trigger rules (It's not your father's SQL query). For example:
'''
// we just insert Customer objects in the WM
rule "evaluateRetired"
when
$c : Customer(age > 65)
then
insertLogical(new Retiree($c));
end
rule "evaluteRetireeIsFemale"
when
$r : Retiree(customer.gender == Gender.FEMALE, $c : customer)
then
...
end
'''
If the decision diagram frequently changes (and you want non-programmers to edit it), take a look at the documentation on (and ). In that case you'll probably repeat the entire path for each rule, but that's actually ok in most cases. | |

Most likely you will need some code to read environment var that identifies platform so you can issue correct command and rely on users of different Linux flavors to report when default fails and report to you the correct command line parameters. OTOH you could limit supprt to only those platforms you have access to. Or combination of these approaches. | |

<IMAGE> | , firebase push keys have the very handy feature of sorting chronological, meaning just apply alphanumeric sort and they will be in chronological order even for offline writes.
Ideally, you design your document in such a way that you don't need to query them.
Or in other words, store the documents as you expect the results of your queries.
# Applying to an app
Let's suppose:
1. You have a view in your app showing the start datetime, # of teams joined, and prize, for all events in a given sport.
2. Clicking any of the events, you have a view showing start datetime, end datetime, venue, sponsors, and the team name of all teams joined.

<IMAGE> | I FINALLY FIXED IT AFTER 3 DAYS! Ok, so it was indeed because my two java classes were in a default package. So to fix that, since my classes were being accessed via a different package, I created a new package that was my app (com.example.awesomefilebuilderwidget) and then moved the classes into there and now it works with no problemos! :DD Thanks for all you've done I really do apperciate it! - user1628978 | |
29,843,856 | 1 | 29,847,707 | I have a fairly simply computation I need to do, but I cannot figure out how to do it in a way that is even close to efficient. I have a large nxn matrix, and I need to compute the following:
<IMAGE>
I'm still fairly inexperienced at coding, and so the only way that comes to my mind is to do the straightforward thing and use 3 for loops to move across the indexes:
'''
sum=0
for(i in 1:n)
{
for(j in 1:n)
{
for(k in 1:n)
{
sum = sum + A[i,j]*A[j,k]
}
}
}
'''
Needless to say, for any decent size matrix this takes forever to run. I know there must be a better, more efficient way to do this, but I cannot figure it out. | If you don't consider the 'k' and 'i' sums, you can realise that you are just doing the matrix product of 'A' with itself. Such product in R is obtained through the '%*%' operator. After calculating this matrix, you just need to sum all the elements together:
'''
sum(A %*% A)
'''
should give the result you are seeking. | |

Here is how it looks like
<IMAGE>
I have shown the list in right panel using another ng-repeat where I am just showing titles of notes and a button to maximize if they are hidden (constraint is I cannot have both left and right panels in single ng-repeat). Now the problem is whenever I click minimize button, that particular item hides, But I am now unable to display it again using maximize button in right panel.
I tried creating a function in controller for ng-click of minimize button which will return true if current state of item is 'not hidden' and I have passed a variable to the same function via ng-click of maximize button setting it up as false for ng-hide. But it's not working.
I am fed up now. If you guys got the purpose, please help me achieving the same. :(
