I'm not an expert in stopping time, but I don't think that it's true that $$\bigcup_{s<t}\{X_s\leq x\}=\bigcup_{\substack{s<t\\ s\in \mathbb Q}}\{X_s\leq x\}.$$
Take $X_s=|s-\sqrt 2|$. Then if $t>\sqrt 2$, $$\bigcup_{s\leq t}\{X_s\leq 0\}=\{X_{\sqrt 2}=0\}$$
but $$\bigcup_{\substack{s\leq t\\s\in \mathbb Q}}\{X_s\leq 0\}=\varnothing .$$
Nevertheless, this can be fix in considering $\{X_{\tau}<x\}$ instead of $\{X_\tau\leq x\}$ (since $\{(-\infty ,a)\mid a\in\mathbb R\}$ is a $\pi-$system generating Borel sets).

why they can say that $y=y(x)$ ? It looks a bit strange for me. In other word, why can I say that $$xy^3+x^3y=4\implies \exists y\in \mathcal C^1(\mathbb R): xy(x)^2+x^3y(x)=4\ \ ?$$

The ViewModels access the same Model. The Views need the data from the same Model in a different format. The ViewModels handle the formatting and validation.
Both ViewModels should be able to communicate with each other in some way. For example if ViewModel1 updates something in the Model ViewModel2 should also update his View. The ViewModels don't have to know each other, they should just get synced when one side changes something.
I found some old posts aout the Mediator pattern. Is this still the way to go? I think the Observer pattern would not work here. The only alternative I could think of was to create a Interface on both ViewModels which let them talk to each other.

As said above, you could add a self update command to your build, but that will not update the targets or config files if there are changes between versions (or remove the reference from your solution). Perhaps its not that big of a deal, but this is the sure fire way to make sure you have the latest exe and configuration files. And at the end of the day, updating is only an issue if you need access to a new command or there is eventually a breaking change in a new release.

Obviously, that's a lot of work when you are already stuck with the File API.
Another option is to forget Mockito entirely and write those files on the system. I usually avoid that, as it sometimes make it harder to have tests run in parallel on some systems.
For this specific situation, my solution is generally to provide a special class, say FileBuilder, that can instantiate new Files:
public class FileBuilder {
public java.io.File newFile(String pathname) {
return new java.io.File(pathname);
}
}
I then mock this class before passing it to MyClass, and instrument it as appropriate:
@Test(expected = Exception.class)
public void should_fail_when_file1_is_bigger_than_file2() {
FileBuilder mockFile1 = file(2L);
FileBuilder mockFile2 = file(1L);
FileBuilder mockFileBuilder = mock(FileBuilder.class);
when(mockFileBuilder.newFile("file1").thenReturn(mockFile1);
when(mockFileBuilder.newFile("file2").thenReturn(mockFile2);
new MyClass(mockFileBuilder).myMethodSpaceCheck();
}
private static File file(long length) {
File mockFile = mock(File.class);
when(mockFile.length()).thenReturn(length);
return mockFile;
}
(your example mentions File.size(); I assumed you meant File.length())
The actual implementation of MyClass would look like this:
public class MyClass {
private String file1;
private String file2;
private final FileBuilder fileBuilder;
public MyClass() {
this(new FileBuilder());
}
@VisibleForTesting
MyClass(FileBuilder fileBuilder) {
this.fileBuilder = fileBuilder;
}
public void myMethodSpaceCheck() //...
}

Conferences such as Agile 2009 have a plethora of presentations on Continuous Integration, and testing techniques and tools. Technical conference such as Devoxx and Jazoon also have their fair share of those subjects.
There is even a whole conference dedicated to Continuous Integration & Testing (CITCON, which takes place 3 times a year on 3 continents).
In fact, my personal feeling is that those talks are so common, that they are on the verge of being totally boring to me.
And in my experience as a consultant, consulting on code quality techniques & tools is actually quite easy to sell (though not very highly paid).
That said, though I think that Code Quality is a popular subject to discuss, I would rather agree with the fact that developers do not (in general) do good, or enough, tests. I do have a reasonably simple explanation to that fact.
Essentially, it boils down to the fact that those techniques are still reasonably new (TDD is 15 years old, CI less than 10) and they have to compete with 1) managers, 2) developers whose ways "have worked well enough so far" (whatever that means).
In the words of <PERSON>, modern Code Quality techniques are still early in the adoption curve. It will take time until the entire industry adopts them.
The good news, however, is that I now meet developers fresh from university that have been taught TDD and are truly interested in it. That is a recent development. Once enough of those have arrived on the market, the industry will have no choice but to change.

I beg to differ.
The problem with public key authentication is that it converts the authentication mode from "something you know" to "something you have in your home folder".
Consider the attack propagation. If a single machine is compromised, you are better off containing the attack within the same machine when using password based authentication rather than a public key - using which every machine is compromised.
My opinion is if scripts are not used in the server - that store the password, having password authentication and account lockout for bruteforce is much stronger than public key.
When scripts are present -
1. Ensure that scripts run as least privileged user as possible and use public key authentication for the scripts to access other machines.
2. It scripts require root privileges to run, still use the same unprivileged account and use a local executable with suid (accessible only to the script) to run the privileged command.
Any thoughts?

The browser 500 error that you were experiencing was due to many of the PHP modules not loading. When a suPHP directive is active in the .htaccess file of the document root or any of its parent folders, it will prevent the default .ini files for EasyApache4 versions of PHP from being loaded. I have corrected this issue by commenting out the suPHP directive in the home directory .htaccess.

Highlight the bullet text by dragging from first letter in word to the end last word only.
If you go pass the last letter you will see a half empty space highlighted.
Drag the cursor back to end of the last letter if you also hightlight the half space.
Copy the line (unfortunately, only one line at a time).
That half empty space (end of each bullet) is the hidden formatting of the bullet. If you copy (double, triple clicking by default), you also copy the bullet or list number.

A simple:
London['London_sun_mins'] = np.where(London['time']>=London['London_sunrise'], '60', '0')
Gets close to the required output, however, when I try to extend to:
London['London_sun_mins'] = np.where(London['time']>=London['London_sunrise'], London['time'] - London['London_sunrise'], '0')
The following error is returned:

Also, when extending to encompass both sunrise and sunset:
London['sunlightmins'] = London[(London['London_sunrise'] >= London['date_time'] & London['London_sunset'] <= London['date_time'])]
London['London_sun_mins'] = np.where(np.logical_and(np.greater_equal(London['time'],London['London_sunrise']),np.less_equal(London['time'],London['London_sunset'])))

I'd like to pass the selected objects to the ng-model and have it mapped to my options, containing objects of the same structure, but not from the same source:
<div ng-repeat="training in trainings">
<form class="form-horizontal" role="form">
<ui-select multiple ng-model="training.skills" theme="select2" ng-disabled="disabled">
<ui-select-match placeholder="Wähle Skills...">{{$item.name}}</ui-select-match>

<span>{{skill.name}}</span>
</ui-select-choices>
</ui-select>
</form>
</div>
The trainings list from ng-repeat with an example training looks like this:
[{"description": "",
"skills": [{"type": "tech",
"name": "C",
"id": 194}],
"id": 1,
"name": "Test"}]
My skills list from ui-select-choices contains the same data structure as in training.skills:
[{"type": "tech",
"name": "C#",
"id": 194},
{"type": "tech",
"name": "Java",
"id": 197},
...]
Unfortunatly this doesn't work. The ui-select empties my training.skills, showing me an blank select field. I understand that angularjs is not able to map those objects, if they do not origin the same array, like stated in this blogpost. It suggests using track by to tell ui.select which property to use to map the two lists of objects, but if i change the ui-select-choices line to:
<ui-select-choices group-by="skillTypeGrp" repeat="skill.id as skill in skills track by skill.id | filter: $select.search">
nothing changes.
Is there any possibility to get this running without replacing my objects by their ids like the single property binding example suggests?

So the tileset grass-tiles-2-small.png you used is not embedded and has to be loaded, too. Fortunately this is done automatically by resolving the image dependencies for you.
So additionally to map.tmx you have to make sure that all used image files are reachable by copying them to your assets folder. It has to look like this: assets/tileset 2/grass-tiles-2-small.png. Refresh your Eclipse project after doing so, just in case it didn't notice.
If you already did that, another source of the problem could be the whitespace in your directory name. Try to rename tileset 2 to tileset_2 and create a new .tmx file.

This way I can stop execution process in any point of my application by binding.pry and can execute code many times, not waiting of full Rails environment restart each time.
I have this code in my .pryrc file:
Pry.config.commands.command "zze", 'Execute all from .pry_exec/zze.rb' do
Dir['.pry_exec/autoload/**/*.rb']
.delete_if {|file| File.basename(file) =~ /^_/} # inore files that starting form underscore '_'
.each { |f| load(f) }
file_name = File.absolute_path '.pry_exec/zze.rb'
code = File.open(file_name, 'r') {|f| f.read}
eval(code, @target, file_name)
end
and have folder <myproject>/.pry_exec/:
<myproject>/.pry_exec/ # ignored from CVS
autoload/ # this folder loads automatically each `zze` call in cosnole
some_class1.rb
some_code2.rb
zze.rb # this file loads automatically each `zze` call in console.
Sometimes there are cases, when it would be good to use binding.pry inside <myproject>/zze.rb or <myproject>/autoload/some_class1.rb but it does not working. It just ignore that.
I also tried to rewrite zze-code this way:
# ~/.pryrc
def zze(name = nil)
Dir['.pry_exec/autoload/**/*.rb']
.delete_if {|file| File.basename(file) =~ /^_/} # inore files that starting form underscore '_'
.each { |f| load(f) }
load ".pry_exec/#{name || 'zze'}.rb"
# instance_eval(File.read(".pry_exec/#{name || 'zze'}.rb"))
end
but it also ignore binding.pry inside <myproject>/zze.rb or <myproject>/autoload/some_class1.rb
Also when zze is not pry-command, but is method, code from zze.rb executes inside another scope, and I will not have access to local variables defined from zze.rb in my pry-main context. Didn't find how to fix that yet with short way.

As you can see in above example code, element tag of author, and text node of title in first book element has extra spaces. Similarly element tag of second book element has extra spaces.
I want a regular expression to search for these types of white spaces (more than 1 adjacent whitespace), but I don't want the leading white spaces. If I don't leave leading whitespaces (starting of the lines), and replace these with single space, indentation will be lost.
There are some ways I can handle this (like first removing all double+ spaces and the doing a xmllint --format on the file), but it would be helpful if someone can give me a reg exp for spaces in middle of lines.
i tried combinations of ^, \s and ^\s, but I cannot seem to get the solution. So if someone can suggest something, it would be really helpful. (The multiple spaces in text nodes are incorrect values as per our project's design. So removing them will not cause any adverse affect)

The first loop goes through each row, and saves the parID, Lline, and keep over the last value in each of those variables. After the loop, they only have the values from the last row because that was the only row to not have another one come along after it and overwrite the values.
You can solve this by combining the actions into a single loop.
maxRow = ws.max_row + 1
for row in range(2, maxRow):
parID = ws['A' + str(row)].value
Lline = ws['B' + str(row)].value

In our case, Business Action maps to the Transaction command and provides the business intent or what the user is doing in business terms. So in our case, where we are modelling the lifecycle of a loan, an action might be to "Close" the loan.
We model Event at a state level as follows: Each Event encapsulates a Transaction Command and is uniquely identified by a (TxnHash, OutputIndex) and a created/consumed status.
We would prefer a polling mechanism to generate events on demand, but an asynch approach to generate events on ledger changes would be acceptable. Either way our challenge is in getting the Command from the Transaction.
We considered querying the States using the Vault Query API vaultQueryBy() for the polling solution (or vaultTrackBy() for the asynch Obvservalble Stream solution). We were able to create a flow that gets the txn for a state. This had to be done in a flow, as Corda deprecated the function that would have allowed us to do this in our Springboot client. In the client we use vaultQueryBy() to get a list of States. Then we call a flow that iterates over the states, gets txHash from each StateRef and then calls serviceHub.validatedTransactions.getTransaction(txHash) to get signedTransaction from which we can ultimately retrieve the Command. Is this the best or recommended approach?
Alternatively, we have also thought of generating events of the Transaction by querying for transactions and then building the Event for each input and output state in the transaction. If we go this route what's the best way to query transactions from the vault? Is there an Observable Stream-based option?
I assume this mapping of states to command is a common requirement for observers of the ledger because it is standard to drive contract logic off the transaction command and quite natural to have the command map to the user intent.
What is the best way to generate events that encapsulate the transaction command for each state created or consumed on the ledger?

I would think a better solution would be for the platform to provide consumers access to transaction-level information (selectively perhaps) just as it does for states. After all, the transaction is, in part, a business/functional construct that is meaningful at the client application level. For example, If I am "transferring" a loan, that may be a complex business transaction that involves many input and output states and may be an important construct/notion for the client application to manage.

The problem domain
I am currently using DocumentDB to model some data which I would like to search. My document, which I shall call "Entity A" at the moment looks something like:
{
_id, //key - Guid
name, //searchable - String
description, //searchable - String
tags: [ "T1", "T2", ...] //facet - Collection(String)
locations: [
{
coordinate, //filter - GeoLocation (lat & long)
startDateTime, //filter - DateTimeOffset
endDateTime //filter - DateTimeOffset
},
...
]
...
},
...
Relationships:
tags 0...n Entity A & locations 0...n Entity A
Flattening Entity A and setting up a simple index and query for name, description and facet for tags is fine and working great.
The problem lies in trying to add locations to index. Effectively what I want to search (in natural language) is:
For a given term, find all the Entity As near a coordinate that overlap with x start date and y end date
From what I can find online - flattening the locations will only work if they become strings.
https://blogs.msdn.microsoft.com/kaevans/2015/03/09/indexing-documentdb-with-azure-seach/
https://learn.microsoft.com/en-us/azure/search/search-howto-index-json-blobs
This seems to lose the power of being able to perform geodistance, and date range queries.
Current Thoughts
Split the Entity A document into two collections
The new Entity A document:
{
_id, //key - Guid
name, //searchable - String
description, //searchable - String
tags: [ "T1", "T2", ...] //facet - Collection(String)
...
},
and multiple location entities
{
_id,
documentId, //relates to Document._id
coordinate,
startDate,
endDate
}
Questions:
Is it better to have two indices - one for the new Entity A and one for the locations and then join the results?
I think this is the Multitenant Search
https://learn.microsoft.com/en-us/azure/search/search-modeling-multitenant-saas-applications
Does anyone know of an examples that implement this?
Pros
Think it will work
Cons
Would require two search hits for each query and then merging the results (this may or may not be ideal).
OR
Is is better to fully "invert" the Entity A and location entities, ie something like
{
_id,
documentDBId, //relates to Document._id
coordinate,
startDate,
endDate,
name,
description,
tags: []
...
}
Pros
Pretty flat already so should be easy to index and query
One search hit and no merging
Cons
For name, description, tags, etc it would required multiple updates
if these changed.
Would get multiple results for the same "Entity A"
if the date spanned multiple start and end dates
OR
Is there another option?
Thanks and I'm happy to clarify if needed

Some scholars have ruled photographs as separate from the prohibition of making images, suggesting it is a capture of images instead. Regardless, even they have said it is better to not take photographs, so as to stay away from doubtful matters, as the Prophet said:
عَنِ النُّعْمَانِ بْنِ بَشِيرٍ ـ رضى الله عنه ـ قَالَ قَالَ النَّبِيُّ
صلى الله عليه وسلم " الْحَلاَلُ بَيِّنٌ، وَالْحَرَامُ بَيِّنٌ
وَبَيْنَهُمَا أُمُورٌ مُشْتَبِهَةٌ، فَمَنْ تَرَكَ مَا شُبِّهَ عَلَيْهِ
مِنَ الإِثْمِ كَانَ لِمَا اسْتَبَانَ أَتْرَكَ، وَمَنِ اجْتَرَأَ عَلَى

يُوشِكْ أَنْ يُوَاقِعَهُ
Narrated <PERSON>: The Prophet (ﷺ) said "Both legal and
illegal things are obvious, and in between them are (suspicious)
doubtful matters. So whoever forsakes those doubtful things lest he
may commit a sin, will definitely avoid what is clearly illegal; and
whoever indulges in these (suspicious) doubtful things bravely, is
likely to commit what is clearly illegal. Sins are Allah's Hima (i.e.
private pasture) and whoever pastures (his sheep) near it, is likely
to get in it at any moment." (Bukhari)
For extensive discussion on further proofs, see: https://islamqa.info/en/search?q=photography
In addition, I will also say that many girls on facebook and other places are treating the hijab as a fashion statement, and are utilizing different hijab "fashions" in order to draw attention to themselves. This is known to anyone who has the faintest awareness of the different popular social media platforms. If you abide by the hadith above, this situation would not even arise as with or without hijab, all of it is at the very least makrooh (condemned/disliked).

Defrag
Repartition to have a small partition in which you unpack the .iso
Install grub (That's the tricky one. you'll have to use grub4dos. The PuppyLinux wiki has a good walkthrough, although they do it slightly differently than I suggest)
Boot from the new partition
install fedora over the XP partition
boot into fedora and remove the partition in which you've unpacked the .iso
resize the fedora partitions appropriately to recover the lost space.
But it remains easier to grab your disk and get a friend to install it for you on a separate machine.
for more info on remote, headless installs have a look at the depenguinator or The Archlinux wiki. You have the advantage of having access to the screen/kbd and so don't need to set up ssh.

In fact, both Array.prototype.map() and Array.prototype.forEach() are very similar, with similar interfaces, just begin your invocation with the name of the array. So instead of jQuery $.map(data, notification => { return notification.template }), it's data.map(notification => notification.template) or similar. And the only difference between native map() and forEach() is that forEach() applies the function to each item in the array, while map() goes one step further and returns a new array of resulting values if invoked correctly.

You are mixing PHP syntax with JavaScript syntax here:
$.post("action.php?module=cart&act=del&id=$_GET[id]");
If you view the source of this page, you will find that the end of this line has not been parsed into anything useful.
As other users have pointed out, you are sending this request via POST, not GET, but you are passing this parameter in a querystring so it should still be there.But, because of the problem above, you will find that $id does not contain the ID, but a string containing "$_GET[id]". However, since you don't appear to be POSTing any parameters, better to just send this as a GET in my opinion.
I assume you want something like this:
$.get("action.php?module=cart&act=del&id=<?php echo $_GET['id']; ?>");
That way, assuming that the page on which this is being run is being parsed as PHP and assuming that id is being set to something in the querystring, that value will be parsed and added into the JavaScript.
Good luck!

Where the return $V$ could be written as "how good is an action $Q$ $\times$ probability of taking that action $\pi$".
Consider the policy gradient, $\nabla_\theta V = \sum_a Q \nabla_\theta \pi + \pi \nabla_\theta Q$
The first term tells us to adjust the action probability proportionally to how good it is. To me it could read "if an action yields good, take more". That is to move the peak of $\pi$ to match the peak of $Q$. This is a reasonable thing to do. But of course since $Q$ cannot directly guide us toward its peak, it is up to our $\pi$ to luckily stumble upon the high peak of $Q$. This emphasizes the importance of exploratory nature of $\pi$.
The second term is vice versa. That is to move the peak of $Q$ to match the peak of $\pi$. This is much harder a task because $Q$ is a function of both action and policy, $Q_{\pi_\theta}(s, a)$. We clearly don't have this in a differentiable form i.e. we don't have a universal $Q$ function over the space of all possible $\pi$.
We now have a partial gradient from the first term but we have yet to estimate the second term.
Turns out, the second term can be recursively written solely in the form of the first term but with subsequent actions and states.
$$
\nabla_\theta V_0 = \sum Q_0 \nabla_\theta \pi_0 + \sum Q_1 \nabla_\theta \pi_1 + \sum Q_2 \nabla_\theta \pi_2 + \dots
$$
That is to get good policy i.e. policy gradient we only need to move the peaks of $\pi$ to match the peaks of $Q$ not only the first (state, action) but also for all subsequent (state, action)'s. This yields the same result as if we differentiate through the $Q$.

Sometimes the code may need to be executed via a separate script, and in theory you could assemble a virus from multiple images that contained code hidden within the picture using stenography but there are easier ways.
Basically many computer systems expected images to comply with the exact specification for the type and the failed to correctly range check the formats/parameters being passed.
By 'engineering' an image so that externally it looks like it complies but internally it does not, it was to be possible to trigger stack corruption/buffer overflows that would allow code hidden in an image to be executed under the authority of the user.
But note that this does not ONLY apply to images, it can apply to ANY file, take a look at the recent RTF exploit in MS word.

Consider expanding everything out to get a sum of elements of the form $\pm \frac1i \cdot \frac1j$. Fix $i$ and $j$ for $i\leq j$, and consider all occurrences of $\pm\frac1i \cdot \frac1j$. If $i<j$, then this occurs twice in each of the first $i$ original terms, each with sign $(-1)^{j-i}$, so they sum up to $(-1)^{j-i}\cdot\frac2j$. If $i=j$, then this occurs once in each of the first $j$ original terms, each with sign $+1$, so they sum up to $\frac1j$.
Now let's fix $j$ and aggregate all $\pm\frac1i \cdot \frac1j$ with $i\leq j$. This value is $\displaystyle\sum\limits_{i=1}^{j-1} (-1)^{j-i}\cdot\frac2j + \frac1j$, which is easily seen to be just $(-1)^{j-1}\cdot\frac1j$. Finally, we sum over all $j$ to get $\displaystyle\sum\limits_{j=1}^\infty (-1)^{j-1} \cdot \frac 1j$, which is your $b_0$.

After many attemptions, I've noticed the problem was on my server side.
The two sensor data was sent from one device with ~10ms difference and the message sending was not in Notification mode but Indication.
I have not noticed it before, because I have sent only 1 sensor data with 2 seconds difference but problem came when I was trying to send 2 messages almost simultaneously.
After setting it to Notification, the server could send messages rapidly (did not need acknoledgement).
I know this error was not caused by pydbus in the end, but by my fault. I hope that if someone finds a similar problem, they should check the sender (server) side as well.

The web application redirects the user's browser to CAS's login URL with a "service" parameter, for instance https://cas.com/login?service=http://myapp.com.
Once the user has been authenticated by CAS, CAS redirects the authenticated user back to the application, and it will append a parameter named "ticket" to the redirected URL. Its ticket value is the one-time identification of a "service ticket". For instance, http://myapp.com/?ticket=abcdefg.
The application can then connect to the CAS "serviceValidate" endpoint to validate the one-time service ticket. For instance, https://cas.com/serviceValidate?service=http://myapp.com&ticket=abcdefg.
In response, CAS shall return an XML containing the authenticated user id, for instance,
<cas:serviceResponse>
<cas:authenticationSuccess>
<cas:user>johnd</cas:user>
</cas:authenticationSuccess>
</cas:serviceResponse>
I've done some research and found it could be implemented in mainly two ways:
Serve react as part of Django's static content.
Standalone react single page application(SPA) through JWT.
I've tried the first approach and it works, but the problem is that every time I want to test the authentication with React, I need to build the static file first and put them in Django, which is kind of slow. So I would like to try the second approach.
My question is that is there any best practice I could implement for the standalone approach? If I were to implement JWT, is it safe to store the access token in localStorage or cookie?
Many Thanks!

In my case, I only edit the content of a tag. I don't need to check inner or outer tags, it's no 'difficult' things. So, I personally think that sed is enough.
In conclusion yes an XML parser is the best, but here sed might be OK. If our needs increases in complexity (XML or HTML complexity I mean) I will do my best to make an XML parser be installed on our servers. |

I need to get the CSV to behave like a map structure and it has to be in memory. I couldn't find a way to expose awk variables back to the shell so I thought of using bash associative arrays.
The problem is that loading the csv into an associative array gets very slow/stuck after ~8 mil rows. I've been trying to eliminate the causes of slowdown that I could think of: file reading/IO, associative arraylimitations. So, I have a couple of functions that read the file into an associative array, but all of them have the same slowness problem.
Here is the test data
loadSplittedFilesViaMultipleArrays -> assumes the original file was split into smaller files (1 mil rows) and uses a while read loop to build 4 associative arrays (max 3 mil records each)
loadSingleFileViaReadarray -> uses readarray to read the original file into a temp array and then goes through that to build the associative array
loadSingleFileViaWhileRead -> uses a while read loop to build the associative array
But I can't seem to figure it out. Maybe this way of doing it is completely wrong... Can anyone pitch in with some suggestions?

Initially I thought that the PAC_LOGON_INFO structure has changed since the last jaaslounge implementation was written (somewhere in 2010). I thought that because the MS-PAC specification does not mention it at all.
Actually, the problem is coming from a completely different place: the KDC. It's running on a Win Server 2012, version in which Microsoft added by default resource SID Compression.
There you have it, if you turn off resource SID Compression on the KDC, everything will start working (no need to touch anything else, i.e. the version of jaaslounge or to patch hava with an unlimited JCE policy).

When I download the table, I get the message: "Excel cannot open the file 'Test.xlsx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file." When I manually change the name of the downloaded file to 'Test.xls', I'm able to open the file fine (with a small warning that the file format and extension don't match).
Here is the link to table2excel.js: https://github.com/rainabba/jquery-table2excel/blob/377b933ae6b04f4c1826acc24a2bb0a049933f8b/dist/jquery.table2excel.js
Some of the things I've tried:
1. I changed e.uri from "e.uri = data:application/vnd.ms-excel;base64," to "e.uri = "data:application/msexcel;base64,"
2. I changed
. . . 'return ( settings.filename ? settings.filename : "table2excel") + ".xlsx"'; to
. . . 'return ( settings.filename ? settings.filename : "table2excel") + ".xls"';
(when making this change, the file was saved as Test.xls.xlsx and still had the same problem opening the .xlsx file).
How can I get the file to save as .xls rather than xlsx? Or is there a way to make this work while still saving the file as .xlsx (presumably by matching the format with the .xlsx extension)?
Note: if it matters, the file Test.xlsx is "plain vanilla" with just text in a bunch of cells. There's no fancy formatting, characters, etc. The text is all Alphanumeric, with just a few special characters such as : ",.#'/@"
Many thanks if any ideas!

(Note: I only call this after $(document).ready, so I don't know why it's not initialized. Any ideas either on how to initialize, or how to use another way to get the current selected tab?

I want to use READ operation from the CRUD I developed which means that I have to invoke a HTTP request (Using RequestJS for example). And then use the response coming from the READ to do some other things.
READ Operation
router.get('/api/example', function(request, response, next) {
//MongoDB Code to fetch a certain doc
exampleModel.find(request.query.key)
.then(function(doc) {response.status(200).json(doc)})
});
So As you see I respond to the user with the json. What I want to do is to use this route and get the JSON response to use in another function. A middleware in a sense.
Other function
function useRead(){
//Make an HTTP Request using localhost:3000/api/example?key=123
useJSON(doc)
}
I understand that I could use requestJS to get the response. But the problem is does it make sense to make a request to localhost:3000/api/example?key=123. and also when i deploy the application on Heroku for example, that URL would not make sense and I think would crash the application as it should use www.myDomain.com instead of localhost:3000, so how do I solve this problem.
I tried to be concise as possible, Sorry if somethings are not clear.

Other API functions also allow the result of a prediction to be a probability for the target class (https://tech.yandex.com/catboost/doc/dg/concepts/python-reference_catboostclassifier_predict-docpage/) - parameter value is called "Probability".
I would like to know
how this is related to probabilities (in case of a binary classification) and
if it can be transformed in such a one using the python API (https://tech.yandex.com/catboost/doc/dg/concepts/python-quickstart-docpage/)?

My answers are:
(1) Exit with... block or sess.close()
(2) Load neural network model (and trained weight) like:
gd = tf.GraphDef.FromString(open(checkpoint + '_frozen.pb', 'rb').read())
inp, predictions = tf.import_graph_def(gd, return_elements=['input:0', 'MobilenetV2/Predictions/Reshape_1:0'])
(3) When you print out model you may see like Tensorflow object <VSR.Backend.TF.Framework.Trainer.VSR object at 0x000001E5DA53C898>
(4) I heard tf.reset_default_graph() and tf.keras.backend.clear_session() from here, but I never make the code work.

In the variable requestedData we have data as ['student', 'teacher']
include = ['student']
exclude = ['dentist+teacher']
Basically + in the exclude means AND, by that it means that user is both dentist and teacher.
Same data with + can appear in include.
In the variable sections am trying to get data which present in both requestedData and include and we remove it if its part of exclude. But before checking for exclude values we need to parse dentist+teacher to remove + and check dentist and teacher individually. So basically in the above example since we don't have both dentist and teacher in requestedData only student will be returned to sections as it is in both include and requestedData.
Same thing need to be done for include if it has data with +.
In the below solution I am able to check data without +. I was wondering how I can parse + and check for AND condition.

l : MN -> NM is enough
to guarantee monadicity of NM. To see this you need a unit and a mult. i'll focus on the mult (the unit is unit_N unitM)
NMNM - l -> NNMM - mult_N mult_M -> NM
This does not guarantee that MN is a monad.
The crucial observation however, comes into play when you have distributive law solutions
l1 : ML -> LM
l2 : NL -> LN
l3 : NM -> MN
thus, LM, LN and MN are monads. The question arises as to whether LMN is a monad (either by
(MN)L -> L(MN)
or by
N(LM) -> (LM)N
We have enough structure to make these maps. However, as <PERSON> observes, we need a hexagonal condition (that amounts to a presentation of the Yang-Baxter equation) to guarantee monadicity of either construction. In fact, with the hexagonal condition, the two different monads coincide.

(gdb) bt 1
(gdb) function1(this=this@entry=0xfff6c20, x1=-1, x2=3, x3=...
and so on. x3 here could be a array/STL vector and by default GDB does not display it.
I am using lot of STL vectors and Blitz arrays in my code.
I have routines in .gdbinit file to display STL vectors, and subroutines in c++ where I can make use of call functionality in GDB, which can display the array contents. To manually print the vector/array contents, I would use
(gdb) printVector vector_name -> this is a routine in my .gdbinit
(gdb) call printBlitzArray(array_name) -> this is a routine inside my executable itself.
How can we make GDB display the non trivial arguments of a function like below.
void myFunc(int x1, int x2, std<IP_ADDRESS>vector<int> x3, blitz<IP_ADDRESS>Array<bool, 1> x4)
I got to know using set print frame-arguments all can display some of the non trivial arguments.
But how to really print arguments where GDB may not have a native support for printing them.
The intent is to automatically print all the arguments at the start of the function (atleast whichever we can).
I can write a GDB script and add prints individually for each vector/array, but doing this for every function would be very time consuming, since I have a large number of functions. This would help a lot to accelerate my debug.
Any suggestion is highly appreciated.
Thanks a lot in advance !

Open Windows settings
Click "Devices"
Make sure it's on "Bluetooth & other devices"
Click on the device you want to remove
Click "Remove device"
Now go back into your Device Manager and make sure all the drivers are uninstalled. If they remain then uninstall them.
Then restart the PC without installing any other drivers yet! If it restarts and the drivers are gone then the issue is fixed and you can !
I'm suspecting that it is reinstalling the drivers because it still sees the device as being attached to the PC in the Settings menu, but doesn't have a driver for that device. Windows automatically downloads and installs drivers for devices that it is attached to. This causes the drivers to reappear and cause the issue you're dealing with.
Hope this fixes your issue! ~TJ

for (int i = 0; i < fromTagList.size(); i++) {

my code for closing the tab:

documentPane // DocumentPane, containing the dc
documentPane.Items.Remove(dc);
this did the job of closing the tab, but learned that I need to call
dc.Close();

In order to achieve that OpenCV has to be built from source with _contrib. So I compiled it without errors and could also see BRIEF.cpp.o beeing built in the command window.
So when I try to use it, my android app crashes throwing
OpenCV Error: Bad argument (Specified descriptor extractor type is not supported.) in static cv<IP_ADDRESS>javaDescriptorExtractor* cv<IP_ADDRESS>javaDescriptorExtractor<IP_ADDRESS>create(int), file /home/maksim/workspace/android-pack/opencv/modules/features2d/misc/java/src/cpp/features2d_manual.hpp, line 374
So I checked features2d_manual.hpp. Line 374 is the default expression of a switch case block:
CV_WRAP static javaDescriptorExtractor* create( int extractorType )
{
//String name;
if (extractorType > OPPONENTEXTRACTOR)
{
//name = "Opponent";
extractorType -= OPPONENTEXTRACTOR;
}
Ptr<DescriptorExtractor> de;
switch(extractorType)
{
//case SIFT:
// name = name + "SIFT";
// break;
//case SURF:
// name = name + "SURF";
// break;
case ORB:
de = ORB<IP_ADDRESS>create();
break;
//case BRIEF:
// name = name + "BRIEF";
// break;
case BRISK:
de = BRISK<IP_ADDRESS>create();
break;
//case FREAK:
// name = name + "FREAK";
// break;
case AKAZE:
de = AKAZE<IP_ADDRESS>create();
break;
default: //**this is line 374**
CV_Error( Error<IP_ADDRESS>StsBadArg, "Specified descriptor extractor type is not supported." );
break;
}
return new javaDescriptorExtractor(de);
So the error clearly comes up, because case BRIEF is commented. So I modified it like that:
#include "opencv2/xfeatures2d.hpp"
.
.
.
case BRIEF:
de = xfeatures2d<IP_ADDRESS>BriefDescriptorExtractor<IP_ADDRESS>create();
break;
.
.
.
default:
CV_Error( Error<IP_ADDRESS>StsBadArg, "---TEST--- Specified descriptor extractor type is not supported." );
break;
}
After rebuiling in a fresh directory and using the new build, the exact same error is persistent. Not even "---TEST---" is included with the message.
So I am wondering why my changes do not have any effect.
I am also wondering why the file path is:
/home/maksim/workspace/android-pack/opencv/modules/features2d/misc/java/src/cpp/features2d_manual.hpp
This dirctory doesn't even exist on my system and googling it showed, that /home/maksim/ is part of a lot of different error messages on android.
The actual path before building is:
C:\Users\JJG-CD\Desktop\Build_Workspace\opencv-3.1.0\modules\features2d\misc\java\src\cpp\features2d_manual.hpp
I hope somebody can explain to me what the problem is and eventually give me a hint how to solve it.

I have set below configuration in my server.properties
allow.everyone.if.no.acl.found=false
super.users=User:root;User:kafka
I created an ACL using below command
./kafka-acls.sh --authorizer-properties zookeeper.connect= --add --allow-principal User:imit --allow-host --topic imit --producer --consumer --group imit-consumer-group
and I see below response for it
Current ACLs for resource Topic:imit:
User:imit has Allow permission for operations: Describe from hosts:
User:imit has Allow permission for operations: Read from hosts:
User:imit has Allow permission for operations: Write from hosts:
Note: Values mentioned in <> are replaced with some dummy values in the question and used correctly while creating the ACL
I have following observations:
a) Though I define the rule for imit topic to access for a particular using from a given host yet I can write to the topic from any host using any user account.
b) I am unable to read the messages from topic from any host or any user account (even using the one for which I have defined the rules).
I am running Kafka on RHEL 6.7 and all the users are local.
Appreciate if someone can guide if I am missing any configuration parameters or commands to manage authorization or if Kafka is behaving in a weird way.
Also where can I getting authorization related logs in Kafka?
Thanks & Regards,

Through the job I am trying to read data from a Hive table which uses HBase for its storage.
SparkConf conf = new SparkConf();
JavaSparkContext context = new JavaSparkContext(conf);
HiveContext hiveContext = new HiveContext(context.sc());
hiveContext.setConf("hive.exec.dynamic.partition.mode", "nonstrict"); hiveContext.setConf("spark.sql.hive.convertMetastoreOrc", "false");
hiveContext.setConf("spark.sql.caseSensitive","false");
DataFrame df = hiveContext.sql(task.getQuery());
df.show(100);
I am using below spark-sumbit command to run the job on YARN:

I have already performed a kinit before running the job.
The job is able to communicate with Hive meta-store and parse the query.

The job runs fine when we query a normal Hive table and also on non-kerberized cluster.
Kindly suggest if we need to modify any configuration parameter/code changes to resolve the issue.

So I had:
let datePicker = view.viewWithTag(9) as! UIDatePicker

view.translatesAutoresizingMaskIntoConstraints = true
view.autoresizingMask = .FlexibleHeight
Everything is working fine, when the in-call status bar is toggled the view is smoothly resizing its height.
But when the in-call status bar is visible and the second view controller is presented via
self.presentViewController(vc, animated: true, completion: nil)
with
modalTransitionStyle = .FlipHorizontal
the presenting view jumps 20 points down and at the end of the transition the presented view jumps 20 points up (to the correct position).
How could I prevent this from happening?

{
"_id" : ObjectId("5afc22290c06a67f081fa463"),
"title" : "Cool",
"description" : "this is amazing"
}
And I have putted index on title and description :
db.posts.createIndex( { title: "text", description: "text" } )
The problem is when I search and type for example "amaz" it return the data with "this is amazing" above, while it should return data only when I type "amazing"
db.posts.find({ $text: { $search: 'amaz' } }, (err, results) => {
return res.json(results);
});

and use apache server for static file. The example that I know that is working is on Angular, on angular we just run ng build --prod and this will create a dist folder where there is an index.html. On apache, we just serve the dist folder. But here we use React with webpack that not contain dist folder with an index.html so I don't know how to do that on your project.
PS : Sorry for my english, it's not my native language

I could add a div container below the canvas element, style it like a table and shift it in the background of the canvas. But I was wondering if I can add a grid like http://www.linker.ch/graf/sudoku/sudoku_vorlage.GIF directly via css by referencing only the canvas element. For example with before, after?

But I don't know why: `/tmp` is `1777` which means every user should have the permission to create a directory under `/tmp`. According to the [source code](https://github.com/pulseaudio/pulseaudio/blob/master/src/pulsecore/core-util.c#L1791) there must be something wrong with `mkdir(fn,m)`. I tried to recompile pulseaudio with `-O0 -g` so I can attach `gdb` to it. However, packing a debian package ... hmmmm hard to say. | 5ce96959601d61b5bcd4b8d74220878ac324dbeab842c58541116440ab4c31e5 | ['f4836d04e42d4995987b445088da55b3'] | First, observe that $\lfloor \log N \rfloor < 2\lceil \log N \rceil$ holds for all $N \geq 2$.
Let $n_0 = 2$, $c_1=2$, $f(N)=2\lfloor \log N \rfloor$, $g(N) = 2\lceil \log N \rceil$.
So $$f(N) \leq c_1 \cdot g(N)$$
holds for all $N \geq n_0$.
Next, observe that $\lfloor \log N \rfloor > \frac{1}{2}\lceil \log N \rceil$ is true for all $N \geq 2$.
Let $c_2 = \frac{1}{2}$.
Thus,
$$f(N) \geq c_2 \cdot g(N)$$
Therefore, $$f(N) \in \Theta(g(N))$$
But the second question, it is obvious that the statement is incorrect, so I'll not be proving here.

In such types of problems, you would have a single output neuron with a linear activation (or no activation). You would use MSE or MAE to train your network.
If your problem is time series(where you are using previous values to predict current/next value) then you could try doing multi-variate time series forecasting using LSTMs.
If your problem is not time series, then you could just use a vanilla feed forward neural network. This article explains the concepts of data correlation really well and you might find it useful in deciding what type of neural networks to use based on the type of data and output you have.

python3 and pip3 might be referring to different versions/installations of python. This is why it is best to use virtual environments as it ensures that everything in the virtual environment is using the same python installation.
Here is what I would suggest you to do:
1) First use the python3 installation you have to install virtualenv or any other virtual env manager. I am going to assume you are using virtualenv
2) Then you have to ensure that you use the pip that corresponds to your python3 installation to install virtualenv
python3 -m pip install virtualenv
3) Now use virtualenv to create a new environment. Since virtualenv is installed with python3, in the environment, the python should also be python3
4) Activate the environment and use python --version and pip --version to check the version of python and pip in the environment
Everytime you are working on a new project, you should ideally create a new environment to prevent versioning issues.

In a scenario, state->CA(California), selected and all the counties are selected in County filter, belongs to CA.
Now User selects a few other states, the county filter is refreshed with new list, corresponding to states, but they are un-selected/unchecked. Only CA counties are checked/selected in drop down list.
Can I have a fix to slect all counties all time whenever refresh of states happens.
Thanks,

I need to keep thi process shut for certain time and later restart it.
I used bat file and sheduled the task to stop and start.
I used -->net start BPSAuto --- To start
And --> net stop BPSAuto --- To stop.
Now my problem is once I stop the process it again starts automatically. May be this is because it is in "Automatic" mode. Plesae help me to stop completely. And later restart.
Thanks in Advance...

That may create a nightmare. I personally find it hard and time consuming to navigate huge directory structures.
Instead, I found it helpful to follow advice from <PERSON> Blog and put all components that belong to one module into corresponding folder. That way you also avoid huge directories but rather have more directories with meaningful names.
Now in your question the word "any" is confusing. If you mean to be able to call any single functions, then certainly no - only those you really need. Otherwise - yes:) (see any source on MVC).

Lets say you have a model as below in django; a model is essentially a database table with entries called fields. The property hostname is computed from one or more fields in the model from the database. This circumvents needing another entry in the database table that has to be changed everytime the relevant fields are changed.
The true benefit of using a property is calling object.hostname() vs. object.hostname. The latter is passed along with the object automatically so when we go to a place like a jinja template we can call object.hostname but calling object.hostname() will raise an error.
The example below is a virtualmachine model with a name field and an example of the jinja code where we passed a virtualmachine object.
# PYTHON CODE
class VirtualMachine(models.Model):
name = models.CharField(max_length=128, unique=True)
@property
def hostname(self):
return "{}-{}.{}".format(
gethostname().split('.')[0],
self.name,
settings.EFFICIENT_DOMAIN
)
# JINJA CODE
...start HTML...
Name: {{ object.name }}
# fails
Hostname: {{ object.hostname() }}
# passes
Hostname: {{ object.hostname }}
...end HTML...

check whether JNDI name java:global/RecieverApp/Controller!bean.ControllerRemote exists, there was nice JNDI browser in Glassfish 2.x, but they didn't put it in GF 3 (it should be in GF 4), but you still have good old command line: asadmin list-jndi-entries
check whether your CallerRemote interfaces are in same packages in both applications
there is no need to perform both injection (@EJB) and JNDI lookup, if your class Talker is container-managed (i.e. bean, servlet, etc.) then @EJB annotation will suffice, otherwise use only lookup

If $(M,g_t)$ is a solution of the <PERSON> flow (normalized or not, I don't care), and $i\colon N\hookrightarrow (M,g_0)$ is a submanifold (with the induced metric), what is known about what happens to $(N,i^*g_t)$ in terms of its intrinsic/extrinsic geometry?
This is somewhat vague, so, to be more precise: under what conditions a totally geodesic (resp. minimal) submanifold remains totally geodesic (resp. minimal)? What evolution equation is satisfied by the second fundamental form $B^t_{\xi^t}(X,Y)=g_t(\nabla^t_X Y,\xi^t)$ of $N\subset (M,g_t)$, or shape operator, in the codimension $1$ case? Note that here almost everything depends on $t$: the connection $\nabla^t$, the normal field $\xi^t$ and obviously the metric $g_t$. I tried to take the $t$ derivative using formulas for each of the objects (e.g., the ones found in <PERSON>'s notes), but it got incredibly messy very fast -- and there was nothing I could really read off the formulas. I then did some examples, but the only ones I could do all the computations for were somewhat trivial.
I would be interested in any intuition/results related to the above, it could be for hypersurfaces (instead of general submanifolds), only in low dimensions, etc...

Any thread, which would be scheduled first, would be able to "lock" the mutex in a single machine code operation.
But how are mutexes any good when the threads are running on multiple cores? (Where different threads could be running at the same time on different "cores" at the same time).
I can't seem to grasp the idea of how a multithreaded program would work without any deadlock or race condition on multiple cores?
