The one thing I would caution you about is the use of brtfs' transparent compression feature, which is enabled via mount option. The Hadoop HDFS daemons are aware of the size of the volumes and the freeused for HDFS on a node and the free space thereon, and if you enable compression those size values become "unreal," i.e., an assertion of "50% full" of "500MiB" when the volume is mounted compressed neither means that it can hold only 500MiB nor that it's half full (with compression enabled on a btrfs volume, you can write a file of all zeros that is insanely larger than the volume's actual size). Because of that unreliability and because of the extra CPU overhead that would go into compression and decompression, I would avoid the temptation even though for a lot of data typically going into HDFS the effective compression ratios might be quite favorable.
Another reason to avoid compressing HDFS volumes is that as the daemons rearrange blocks what with your replication setting and all, the machines will be uncompressing blocks on read on one node only to write them back out compressed on another node.
Having said this, one potential feature the Hadoop team may want to consider implementing would be to handle compression at the HDFS level; under that regime blocks would only be compressed or uncompressed when written or read by code, to include the hdfs utility. I'm just not sure it would be worth the CPU overhead, though.

I thought that setting the background-size property to cover would do this but is the image isn't big enough (Which would have to be pretty big) I just get white space once I scroll down the page a little bit. Is there a property that would, say, set the height of the background to 100% then properly scale the image so it has the correct width proportional to the original height?
My solution as of now is having a background color that the image "eases" into, just to make it look smooth.

I have a Draw Interaction constructed with a custom style function (a prototype method of one of my objects), but the problem is that the function will be called with this as Window, so I can't access to my app context.
As I'm not responsible for that call (called by OpenLayers), I can't specify the this I want.
Is there a detail I didn't see in the OpenLayer API, or in javascript (I'm not an expert) that could solve my issue ?
Here is my code :
function MyClass(){
(...)
// This state should impact the draw interaction style
this.myState = someValue;
// My interaction
this.addInteraction = new ol.interaction.Draw({
(...)
style: this.styleFunction
});
}
// My style function which need to access this.myState
MyClass.prototype.styleFunction = function( feature, resolution ) {
// The following this is Window instead of MyClass.this
if( this.myState )
return style1;
else
return style2;
}
Adding MyClass.this as a Window property is not a solution as I may have multiple instances of MyClass.
Thanks for any suggestions

Specifically, if you want to break a repeating-key xor cipher, try to find the value of n that minimizes the Hamming distance between any two n-length blocks of cipher text, and n will generally correspond to the size of the cipher key.
While this strategy worked in that particular case, it wasn't obvious to me why it should work. I've reasoned through it from first principles and come to a few conclusions. Note: I am by no means an expert in cryptography, and it's entirely possible that this argument is specious, or I'm using incorrect terminology.
At a high level... I believe this essentially works in this case because you are encoding an English cipher text using 8-bit bytes, and the entropy of the English language is much lower than the entropy of all possible combinations of 8 bits. i.e. English only has 26 letters, but there are 256 possible combinations of 8 bits. Entropy seems to be preserved via repeating-key xor, and so you are essentially looking for the block size that minimizes it.
This implies that if you found some way implement a repeating-key xor that transformed alphanumeric plain text into alphanumeric cipher text, this method wouldn't work.
More specifically... I reason that the Hamming distance is a metric that survives transformation of the underlying text by repeating-key xor, given that it is applied to blocks of text that match the length of the cipher key. This is fairly easy to show for small block and key sizes. For instance, assume the plain text is 001010, the key is 010, and the cipher is therefore 011000. The Hamming distance between the two halves of the plain text is 2, and the Hamming distance between the two halves of the cipher text is also 2. I'm fairly certain that this scales to any text and key length, again assuming that you are taking the distance between blocks of the same size as the key.
Now consider what I said above, that the entropy of the English language is fairly low compared to the entropy of the entire possible byte space. This implies that the Hamming distance between two blocks of English text will in general be less than the Hamming distance between two blocks of random bytes.
Combine these principles, and it becomes clear that at least in theory, if you pick the correct block size / key size, the Hamming distance will be minimized for the cipher text (because it was already minimized for the plain text and survives the xor transformation). If you don't pick the correct key size, then you are taking the Hamming distance of essentially random bytes, which will in general be much higher.

Subroutines execute in the context of the calling routine. Two virtues: no parameter passing, easy to create. In some languages, subroutines are private to (and are part of) the calling (invoking) routine (see various dialects of BASIC).
direct answer: Section and Paragraph support a different way of thinking about programming. Higher performance than call subprogram. Supports overlays. The "fall thru" aspect can be quite useful, a feature rather than a vice. They may be necessary depending on what you are doing with a specific COBOL compiler.

In c we expect that the storage for "message" is out of scope after return : but the pointer returned points to where the value of "message" used to be. To correct the c, declare and define a local variable with enough space to take the longest message IN THE CALLING FUNCTION. Pass a pointer to that space to the function, rather than returning a dangling pointer. As a side note: in production code, your c code might work for years then unexpectedly show intermittent failures. Please review the scope rules in both c and c#.

They state in their documentation:
The direct use of rsync is not possible. Backup space can, however, be locally
mounted using smbfs, sshfs or ftpfs, which allows a limited use of
rsync. To take full advantage of rsync (such as incremental backups
using hardlinks) an image file must be created, which should be
mounted via loopback. In addition to this, it is also possible to add
encryption via encfs (Encrypted File System) to protect the data.
I've already given it a stab by using Curlftpfs and, well, as it was to be expected that doesn't work very well - I get hangs and timeouts and a plethora of errors.
I would like to try the more "correct" way of solving this as described by the quote above - but how do I actually accomplish this? I've tried googling the matter, but the information out there is conflicting and confusing.
Encryption is not a must-have for me. I just want something that works, the simpler the better :)

The clients all use different headers for their data so I need to map the header options to a single field in a data model.
Example: I have a field Company in the class model and the possible headers I need to read from might be Firm, Company, CompanyName, or Business.
Right now I'm using a large repetitive switch statement to handle this based on the headers that I've seen. This is working but it's really ugly and repetitive.
var map = new Dictionary<string, string>();
var colKey = "";
switch (columnName.ToUpper())
{
case "FIRM":
case "COMPANY":
case "COMPANYNAME":
case "BUSINESS":
colKey = "COMPANY";
if (!map.ContainsKey( colKey ))
{
map.Add( colKey, columnName);
}
break;
case "ADDRESS1":
case "LINE1":
colKey = "LINE1";
if (!map.ContainsKey ( colKey ))
{
map.Add( colKey, columnName);
}
break;
}
Ultimately I need to read the data out of DataRows that may have a variety of headers into a data model. The above code gives me a dictionary I can use to access the data by a known name even though the data's header may not match my data model.
Is there a better way to map/parse these possible header options into a data model field?

You can try to fetch all data before apply GroupBy operation.
Like this:
var vrdetails = vrtemp.ToList().GroupBy(x => x.CompName);
In that case you run GroupBy operation on server side. It will increase volume of transferred data but it can work more effective on Sql server

For SMPS applications the parasitic parameters of a MOSFET are critical, these determine your transition time, your on- resistance, ringing (overshoot when switching) and back-gate breakdown that all relate to effeciency of your SMPS.
This image depicts most of the relevant paracitics for a MOSFET.
For a power switch you typically want:
Very low on resistance (That comes from choosing a wide and short channel MOSFET)
Low input capacitance (expacially the Miller capacitance)
Low paracitic inductance to drain and source to minimise voltage spikes during switching (Think in terms of physically short connections to your other components)
High bake-gate breakdown (high enough to handle whatever voltage spikes your paracitic inductance gives you)
For a gate driver (supposing that's what you mean by inverter) you typically want:
Low input capacitance for fast switching
High drive strength (That is again given by choosing a wide and short channel device. Rule of thumb is to use a MOSFET with 1/3 of the width "W" and 1/3 of the length "L" that your respective power MOSFET has
There is a lot more to this subject than what I've mentioned, but it might be a good place to start. Hope it helps.

If so your Firebase calls aren't retrieving the data in time (.observe is async, so that's where the lag comes from).
What I would suggest doing instead would be to first set the timestamp you're counting down to and post that value to Firebase.
When each device needs the countdown button, they retrieve the timestamp, then set the Timer object to fire in 1 second intervals to retrieve the current time from something like NSDate().timeIntervalFrom1970, find the difference between the two, then set the button text (and deactivate the Timer once the countdown is over). Maybe something like this?:
override func viewDidAppear(_ animated: Bool) {
// get time to count down from
Firestore.firestore().collection("countdown").document("thursday").getDocument { (document, error) in
guard let document = document, document.exists else {
// document doesn't exist
return
}
guard let theTime = document.data() else {
print("Document data was empty.")
return
}
print("Current data: \(theTime)")
let stringData = "\(theTime)"
let finalTime = stringData.substring(from: 9, to: 16)
self.setTimer(for: finalTime)
}
}
// set Timer
func setTimer(for finalTime: String) {
let timer = Timer.scheduledTimer(withTimeInterval: 1.0, repeats: true) { timer in
let timeNow = Date()
let dateFormatter = DateFormatter()
dateFormatter.timeZone = TimeZone(abbreviation: "EDT")
dateFormatter.locale = NSLocale.current
dateFormatter.dateFormat = "HH:mm:ss"
let strDate = dateFormatter.string(from: timeNow)
// stop timer once finalTime reached. Idk what finalDate is but here's if it's formatted the same as strDate is.
guard finalTime != strDate else {
timer.invalidate()
print("countdown over")
return
}
let dateDiff = self.findDateDiff(time1Str: strDate, time2Str: finalTime)
print("This is the countdown time: \(dateDiff)")
}
timer.fire()
}
Also, I would suggest comparing timestamp values as Doubles and then formatting the difference how you need to instead of formatting each variable and then comparing them as strings

I would actually like my code to traverse through the list to get the value associated with the last key, as such
print(my_dict['one']['two']['three'])

So, in your case, when you do:
point.plot(p1,x)
Pandas will look for the index 1993 in the x-direction, i.e, throughout all columns. In other words, you should have 1993 columns.
I tried to reproduce your problem as follows:
import pandas as pd
import numpy as np
df = pd.DataFrame(np.random.randint(0,100,size=(10, 4)), columns=('rok', 'kroliki', 'lisy', 'marchewki'))
data = df[1:]
data=data.astype(float)
x = int(data['kroliki'].max())
y = int(data['lisy'].max())
z = int(data['marchewki'].max())
p = data['rok'].where(data['kroliki'] == x)
q = data['rok'].where(data['lisy'] == y)
r = data['rok'].where(data['marchewki'] == z)
p1 = int(p[p.notnull()])
q1 = int(q[q.notnull()])
r1 = int(r[r.notnull()])
point = pd.DataFrame({'x':[p1],'y':[q1],'z':[r1]})
point.plot((p1,x),(q1,y),(r1,z))
I get the following error:
>>> AttributeError: 'tuple' object has no attribute 'lower'
And when I run each point separately:
>>>> IndexError: index 85 is out of bounds for axis 0 with size 3
To solve it:
import matplotlib.pyplot as plt
plt.plot((point.x, point.y, point.z), (x,y,z),'ko')
And I got the following result:
Hope it helps.

Im currently dealing with the formula in determining the expected number of real roots of random algebraic polynomial,,, and I want to solve for the formula of the standard deviation. I have collected a
number of real roots from 100,000 different random polynomials with degree of 25. I have the following results:
$$Number of real roots==>Number of samples$$
$$1 ==> 2479$$$$3==>24 808$$$$5==>46350$$$$7==>23110$$$$9==>3168$$$$11==>83$$$$13==>2$$
Hence, the expected number of real roots of random algebraic polynomial is asymptotically close to $$\sqrt{n} = \sqrt{25} = 5$$ wherein the actual result based on the given above is $$4.99874$$
Surprisingly, as the number of samples increases, the distribution become more normal.
But the results stated above are arbitrary, but again with sufficiently large number of samples, the result will be close to $$\sqrt{n}.$$
At this point, I want to solve for the formula of standard deviation but since the points are arbitrary, it gives me a hard time to solve for the standard deviation... because points changes everytym a new trial will be perform. Is there a feasible way how to deal with standard deviation with unknown points?

I must know the magnitude (height) of every point x... |

What is geometric or some other meaning of the zeros of the polynomial?
I've encountered a similar expression in the theory of 2D/planar electrical networks, where the zeros are essentially multipliers of harmonic continuation on the networks.

char[] chars = s.toCharArray();
byte[] bytes = s.getBytes("utf-8");
The question then reduces to how to get bytes from a byte stream into String, for which you can use ByteArrayOutputStream, like so:
ByteArrayOutputSteam os = new ByteArrayOutputSteam();
os.write(buffer, 0, buffer.length); // it just stores the bytes, doesn't convert yet.
// several more os.write() calls
s = os.toString("utf-8"); // now it converts the full buffer to a string in the specified encoding.
If you truly want something that has a byte input stream and a character output stream, there isn't a built-in one.

(a) I don't know what you mean by "$d\theta/dt = d\theta /d\infty$". That is more or less a nonsensical statement. A derivative must be with respect to a variable. $\infty$ is not a variable. Besides, derivatives are "all about slopes" and what you are looking for has nothing to do with the slope of the function. You wish to know how the function behaves as t gets "very large" (i.e. as $t \rightarrow \infty$). When we want to know such things we should think about taking limits...
(b) Why take logs? What does a logarithm "do"?
(e) You are trying to find a $t$ when $\theta$ takes on a particular value. So you need to solve the equation for $t$. So, how do you "get $t$ out of the exponent"? The answer to this is connected to why you are having trouble with part (b).

What is meant is that $F$ is a "vector field". That is, $\vec{F}(x,y,z)$ is a function which assigns a vector to every position in 3-space. So $F_x$, $F_y$ and $F_z$ refer to the x, y and z-coordinates of $\vec{F}$ at any location.
Any coordinate of $F$ could be a function of any position coordinate (or of all three).

File path = new File(Environment.getExternalStorageDirectory(), "AppName");
if (!path.exists()) path.mkdirs();
File image = new File(path, fileName);
return getUriForFile(ImagePickerActivity.this, getPackageName(), image);
}
You can then do something with the file by overriding the onActivityResult() method.
NOTE: the File() object accepts two parameters: File(File parent, @NonNull String child) the child must match one of the paths declared in your file_paths.xml. In this case, I used AppName.

So, set a breakpoint in the editor on the line atsRange.Value = reportRange.Value and check at that point the following values (maybe add them as watches?)
atsRange.Rows.Count
atsRange.Columns.Count
reportRange.Rows.Count
reportRange.Columns.Count
I suspect that your dimensions are mismatched quite heavily. And if you assign the values of a smaller range into those of a larger range, any cells beyond the area in the smaller range will be set to '#N/A'. So if atsRange is much bigger than reportRange, you'll get a bunch of '#N/A' values.

So when you try to copy from the one device to the other, it's forcing your cells down to a simple plaintext representation. For evidence of this, you could try pasting that same value into a simple text editor like Notepad - you'll see that the only data in your clipboard are the plaintext values, formatted with tabs and newlines to denote the cell positions.
But, we can get around this! Turn your spreadsheet over to "Formula View Mode" temporarily - you can toggle this on/off with CTRL+` (which is the "backtick" located under the escape button on a standard QWERTY keyboard). Now you'll see all the formulas in your cells instead of the values. If you copy cells, these formulas will be copied. Then you should be able to paste directly into the remote instance of Excel without any issues.

You'll have to set the proper encoding on your string.
That could be as simple as
"string".encode('UTF-8')
Or if the string is improperly tagged you may also have to force_encoding first. ie. it's stored as 'Windows-1252' but not marked as such by Ruby.
"string".force_encoding('Windows-1252').encode('UTF-8')

awk -F, '{c[$1,$2]+=1}END{for (ck in c){split(ck,ca,SUBSEP); print ca[2];g[ca[2]]+=1}for(gk in g){print gk,g[gk]}}' game.csv
This will count first every [COL1,COL2] pairs then for each COL2 it counts how many distinct [COL1,COL2] pairs are nonzero.

You can use "/FA /Fa" options you can use..
In there documents,
CL /FAcs HELLO.CPP
/FA Assembly code; .asm
/FAc Machine and assembly code; .cod
/FAs Source and assembly code; .asm
If /FAcs is specified, the file extension will be .cod
/FAu Causes the output file to be created in UTF-8 format,
with a byte order marker.
By default, the file encoding is ANSI,
but use /FAu if you want a listing file that displays correctly on any system,
or if you are using Unicode source code files as input to the compiler.
If /FAsu is specified, and if a source code file uses Unicode encoding other than UTF-8,
then the code lines in the .asm file may not display correctly.

What did work is passing the value like this:
date_field_tag(:my_thing_end_date, :end_date, value: Date.current.strftime('%Y-%m-%d')
From the docs ( http://apidock.com/rails/v4.0.2/ActionView/Helpers/FormHelper/date_field)
The default value is generated by trying to call “to_date” on the object’s value, which makes it behave as expected for instances of DateTime and ActiveSupport<IP_ADDRESS>TimeWithZone.
So passing the date as a string that would be entered by the user seems to be the solution.
Also, according to this good info on dates and time zones, Date.current is preferable to Time.today: https://robots.thoughtbot.com/its-about-time-zones.

You can only call updated_at on a pre_writing, so you need to make sure you have one first.
Then you need to call the method on the actual object rather than the id.
That can be done with something like
<%= element.pre_writings.first.try(:updated_at) %>
Using try will prevent the error if pre_writings.first is nil.
Or you can add the check in your if:
<% if @classroom.user_id == current_user.id && element.pre_writings.any? %>
<%= element.pre_writings.first.updated_at %>
You may also want to rename element to student for readability since it's the student that has many pre_writings.

Both two routers have their NAT features turned on, and have their private network.
hEX has network <IP_ADDRESS>/23, and hAP has network <IP_ADDRESS>/24. These two local networks are are bound as one local network <IP_ADDRESS><PHONE_NUMBER>, and hAP has network <PHONE_NUMBER>. These two local networks are are bound as one local network <PHONE_NUMBER>. I've confirmed all bridge, routing and DHCP policy are configured and worked as I expected.
After configuring above setting, I'm trying to connect to an public IP ('X') from device attached under hEX, to use this route.
End device -> hEX -> hAP -(NAT)-> Remote server 'X'
To accomplish this, I've added routing policy to 'X' to use IP of VPN server binding interface on hEX as gateway, and confirmed ICMP echo reply is well received, stable, and requires about 9-12 ms to be replied.
However, when I use any software which is using TCP to establish connection(I've not confirmed if UDP is being affected too, but I think it is negative.), something strange happens like this:
Even other TCP packets are replying ASAP, under 50 msec, if TCP connection is established. However, only TCP ACK packet replying SYN, ACK of server is keep being retransmitted for about 10 secs and then handshake process is continued. This behavior is also found while HTTPS connection is established, and is observed at all devices under hEX.
If I remove routing policy to address X, then use route
End device -> hEX -(NAT)-> Remote server 'X', TCP handshake is immediately established.
If I connect to address X on device under hAP, by using route
End device -> hAP -(NAT)-> Remote server 'X', TCP handshake is immediately established.
What is the problem, and how should I fix it?

I don't want to stop running Linux on any of the servers because they do other Linux-only things, so I am thinking of running Windows 7 in a VM under Linux.
The application is a video encoding software that only works in Windows. I'd have Cygwin on the Windows guest OS, scp the input file in, ssh to invoke the encoder, and scp the output file back to the Linux host OS.
Questions:
Will VirtualBox perform OK? Is there a better option?
Is there a way to expose a directory on the Linux host, to the Windows guest, in order to skip the scping?

I looked at file timestamps but found that some VM processes and possibly backup solutions can make them useless.
I tried reading the file in place but ran into issues with the PSDrive type not supporting Get-Content in place. So for better or worse for my solution I started with one of LucD's scripts - the 'Retrieve the logs' script from http://www.lucd.info/2011/02/27/virtual-machine-logging/ which pulls a VMs vmware.log file and copies it to local storage. I then modified it to copy the vmware.log file to a local temp folder, read the last line from the file before deleting the file and return the last line of the log as a PS object.
Note, this is slow and I'm sure my hacks to LucD's script are not elegant, but it does work and I hope if helps someone.
Note: This converts the time value from the log to a PS date object by simple piping the string timestamp from the file into Get-Date. I've read that this does not work as expected for non-US date formatting. For those outside of the US you might want to look into this or just pass the raw timestamp string from the log instead of converting it.
#Examples:
#$lastEventTime = (Get-VM -Name "SomeVM" | Get-VMLogLastEvent).EventTime
#$lastEventTime = Get-VMLogLastEvent -VM "SomeVM" -Path "C:\alternatetemp\"
function Get-VMLogLastEvent{
param(
[parameter(Mandatory=$true,ValueFromPipeline=$true)][PSObject[]]$VM,
[string]$Path=$env:TEMP
)
process{
$report = @()
foreach($obj in $VM){
if($obj.GetType().Name -eq "string"){
$obj = Get-VM -Name $obj
}
$logpath = ($obj.ExtensionData.LayoutEx.File | ?{$_.Name -like "*/vmware.log"}).Name
$dsName = $logPath.Split(']')[0].Trim('[')
$vmPath = $logPath.Split(']')[1].Trim(' ')
$ds = Get-Datastore -Name $dsName
$drvName = "MyDS" + (Get-Random)
$localLog = $Path + "\" + $obj.Name + ".vmware.log"
New-PSDrive -Location $ds -Name $drvName -PSProvider VimDatastore -Root '\' | Out-Null
Copy-DatastoreItem -Item ($drvName + ":" + $vmPath) -Destination $localLog -Force:$true
Remove-PSDrive -Name $drvName -Confirm:$false
$lastEvent = Get-Content -Path $localLog -Tail 1
Remove-Item -Path $localLog -Confirm:$false
$row = "" | Select VM, EventType, Event, EventTime
$row.VM = $obj.Name
($row.EventTime, $row.EventType, $row.Event) = $lastEvent.Split("|")
$row.EventTime = $row.EventTime | Get-Date
$report += $row
}
$report
}
}
That should cover your request, but to expound further on why I needed the detail, which reading between the lines may also benefit you, I'll continue.
I inherited hundreds of legacy VMs that have been powered off from various past acquisitions and divestitures and many of which have been moved between vCenter instances losing all event log detail. When I started my cleanup effort in just one datacenter I had over 60TB of powered off VMs. With the legacy nature of these there was also no detail available on who owned or had any knowledge of these old VMs.
For this I hacked another script I found, also from LucD here: https://communities.vmware.com/thread/540397.
This will take in all the powered off VMs, attempt to determine the time powered off via vCenter event history. I modified it to fall back to the above Get-VMLogLastEvent function to get the final poweroff time of the VM if event log detail is not available.
Error catching could be improved - this will error on VMs where for one reason or another there is no vmware.log file. But quick and dirty I've found this to work and provides the detail on what I need for over 90%.
Again this relies on the above function and for me at least the errors just fail through passing through null values. One could probably remove the errors by adding a check for vmware.log existance before attempting to copy it though this would add a touch more latency in execution due to the slow PSDrive interface to datastores.

The use case is a bit different here - I have a loop checking if an array of VMs can be migrated and if there are any failures to that check the operator can either remediate those until the checks clear or they can opt to "GO" and have those failing VMs excluded from the operation. If something other than GO is typed state remains within the loop.
One downside to this is if the operator inadvertently presses a key the script will be blocked by Read-Host and may not be immediately noticed. If that's a problem for anyone I'm sure they can hack around that ;-)

Currently the generation of these random numbers is causing my program to run quite slowly, however the program only needs them to be calculated to around 5 decimal places.
I'm not entirely sure of how MATLAB generates random numbers, but if there is a way of only calculating them to 5 decimal places then it will (hopefully greatly) speed up my program.
Is there a way of doing such a thing?
Thanks very much.

Fist, there is an issue of numerical instability. Take a look at the values in the inverses - they are very large. This means that the original matrix you are trying to invert has at least one singular value that is very small, meaning that the matrix is difficult to invert.
Secondly, you're trying to invert a non-square matrix. Matrix inverses are actually only unique in the case of square matrices. For non-square matrices, officially matrix inverses don't exists. Instead, the functions you are calling will be finding the left- or right-inverses, but these are in general not unique, and so two different but completely valid implementations of algorithms to find these inverses may give different answers.

If the object you are passing as a parameter (the “options” object) is commonly used across the application, possibly being used to call different functions, the unstructured approach can be useful.
However, if you need to create a specific object to call each of the “doLotsOfThings” functions, it probably isn't worth it and just using old-school parameters could be better.

Normally, the connection to an HTTP server is closed after each response. With HTTP "keep-alive" you keep the underlying TCP connection open until certain criteria are met. What those conditions are depends on the server, which is free to close the connection after an arbitrary timeout or number of requests (just as long as it returns the response to the current request).
When the server closes such a connection the client usually reopens it again, and depending on implementation, may throw an exception or print a warning.

It has less backspin and therefore appears to drop. The camera angle from behind the pitcher is deceiving. Although it appears to drop off suddenly, it is more gradual than it appears. A straight fastball defies gravity quite a bit, as does a split fingered fastball, because they both have backspin. The splitter just does not defy gravity nearly as much. The best splitters have relatively high velocity to mimic a fastball, but reduced backspin to get the “drop” action.

The user's name comes through successfully. However, when I refresh the page - I get TypeError: Cannot read property 'name' of undefined error but how's that so when the name's being displaying on the browser?
Is this issue persisting because it's inside componentDidMount()? That's my only suspicion but I could be wrong. What am I doing wrong here and how can I fix this in a way where whenever the user logs in successfully and refreshes the page, it persists with no issues?

So in our small test mesos dcos cluster we reach 70% cpus resources used multiple times per day.
And services people want to start just get hanging waiting for cpu offers that can be well met on slave nodes but for some reson are not allowed to be allocated.
A typical example would be 7 total cpus unused and 1-3 services looking for cpu offers of 0.5 to 2 cpu resources to use. that can be met. if looking on the node resource over view.
To my question are there a hard limit not allowing more then 70% of the cpus to be allocated at the same time?
And are there a reson for this limit what would be the effect of changing this to a higher value?
And last who do we change the limit?

If you want to get data from an API and pass it to several components I would suggest getting the list of Localite's in a parent component and then pass it via props. A rule of thumb is to have more logic in parent components and less logic in child components.
Example:
<template>
<div>
<localite :localite="listOfLocalites" />
</div>
</template>
Then you can in your localite component get the the prop via props: ["localite"]

your server or on a free service (you can found a lot of them) like https://imgur.com/upload or everyone else

-1 you can work via stylesheet like that:
@QCheckBox<IP_ADDRESS>indicator{
background-color: #0000FF;
}
@
-2 you can copy the qml implementation of the checkbox and change de property like here
ApplicationWindow {
id: window
title: "Stack"
visible: true
width: 300
CheckBox {
id: control
indicator: Rectangle {
implicitWidth: 28
implicitHeight: 28
x: control.mirrored ? control.leftPadding : control.width - width - control.rightPadding
y: control.topPadding + (control.availableHeight - height) / 2
color: control.down ? control.palette.light : control.palette.base
border.width: control.visualFocus ? 2 : 1
border.color: control.visualFocus ? control.palette.highlight : control.palette.mid
ColorImage {
x: (parent.width - width) / 2
y: (parent.height - height) / 2
defaultColor: "#<PHONE_NUMBER>"
color: "blue" // you can add your color here
source: "qrc:/qt-project.org/imports/QtQuick/Controls.2/images/check.png"
visible: control.checkState === Qt.Checked
}
Rectangle {
x: (parent.width - width) / 2
y: (parent.height - height) / 2
width: 16
height: 3
color: control.palette.text

}
}
}
hope it helps , bye

This is how client is connecting to server.
c = TCPSocket.open(ip_address, port)
data = {:user_id => 2, :message => 'hello world'}
c.send(data)
response = c.gets
c.close
It works. However the problem is that I can't get the list of people who are currently chatting in the room because as I shown above, client is constantly opening and closing the connection.
An alternative plan is to run an EventMachine client for each connected user. I am planning to store the client connection in session for each user. In this way I will be using the same question for each user. When the user logs out then I will close the connection.
However if the user walks out then how do I self close the client connection.
Any thoughts.

<IP_ADDRESS>.2 Adjust Terminal Bypass Capacitor
The adjust terminal can be bypassed to ground with a bypass capacitor (CADJ) to improve ripple rejection. This
bypass capacitor prevents ripple from being amplified as the output voltage is increased. At any ripple frequency,
the impedance of the CADJ should be less than R1 to prevent the ripple from being amplified:
1/(2π × fRIPPLE × CADJ) < R1 (1)
The R1 is the resistor between the output and the adjust pin. Its value is normally in the range of 100-200Ω. For
example, with R1 = 124Ω and fRIPPLE = 120Hz, the CADJ should be > 11µF.

You could watch video about how ripples can affect the output here

{{/link-to}}

This achieves the following:

action 'closeNavigationMenu' is invoked

I'm working on an HTML form that manages credit cards. The form has a javascript page that does all the validation and such for it when submitted.
The zip code field on the Form has an onblur action that queries a database for the zip code to populate the city/country fields. In the database, there can be more than one location set up for a zip code, in which a floating div appears to let the user select which address they would like to use.
When it's run, it first disables all the fields on the form with this function piece:
for(f=0;f<document.forms.length;f++)
{
for(i=0;i<document.forms[f].elements.length;i++)
{
if (document.forms[f].elements[i].disabled==true)
keepDisabled += document.forms[f].name + document.forms[f].elements[i].name + "^";
document.forms[f].elements[i].disabled=true;
}
}
Then when the user selects an address, it enables all the fields with this piece:
for(f=0;f<document.forms.length;f++)
{
for(i=0;i<document.forms[f].elements.length;i++)
{
if (keepDisabled.indexOf("^"+document.forms[f].name+document.forms[f].elements[i].name+"^") == -1)
document.forms[f].elements[i].disbaled=true;
}
}
So the disabled = true should be skipped over for any elements in the keepDisabled variable. The odd thing is that it works fine in FireFox/Chrome, but in IE, it sorta half-enables the fields. The disables fields lose the grey-out, the input/text field can't be edited, which is still good, and the select only activates on a double click.
I've also tried using these disabling codes:
document.forms[f].elements[i].prop("disabled", "disabled");
document.forms[f].elements[i].attribute("disabled, "disabled");
Any suggestions? Thanks.

Saliendo de mi tema, te comento que puedes saber el tipo de control de una manera más elegante. Puedes usar `me.ActiveControl.ControlType`, y compararlo con `acComboBox`, `acListBox` o `acTextBox`. O también puedes usar: `If typeof me.activecontrol is ComboBox/ListBox/TextBox then` |

After reading that I still hold the opinion that it's not really that useful. If you really care about lost passwords - go for two factors authentication. If you don't - you'd get more or less the same security with no password expiration. | ae6ddc5c804f7cb8ca18accef5e8430e9cc018eb51ca8e617e7787ecae663956 | ['1985fe2db0be45a8ad51484fa45a0a26'] | On desktops, when web browsing you typically right click on an image and choose an item from a contextual menu to display/copy the image URL. In iOS, when you tap and hold down an image, an action sheet displays asking if you want to save the image, copy to the clipboard, etc. But what if you just want the URL?
If safari doesn't offer this functionality, is there a 3rd party browser that does? Specifically, one that works on the iPad.

My thought was each input of the receiver, D and \D, will swing between VTERM and VTERM-400mV, thus the common mode would be VTERM-200mV. Indeed, when I simulated the circuit with LTSpice, input of CML receiver, D and \D, initially swing between VTERM and VTERM-400mV and input common mode voltage is VTERM-200mV. However the common mode starts to drift to final value of VTERM, D and \D swinging between VTERM+200mV and VTERM-200mV.
Why is that so?
Thank you.

I've read some notes, like this one from Dr. <PERSON> and posts here on StackExchange where people providing pros of placing AC coupling caps near a transmitter.
However I've also seen many other app notes such as this one from TI, SCAA059C that have AC coupling caps located near a receiver but not providing any reason for it. Electrically is there any benefit or reason to place AC coupling caps near a receiver?
Also, I've seen some designs where caps are placed like below. If caps on transmitter side (or receiver side) is better , why would one design like below? Could there be any practical reason why below locations might provide more benefits?

To create new surface area, you need to supply this energy to the material by doing work on it. As the blade thins out, the closer the work you expend becomes to the minimum surface energy. That's asymptotic behavior with asymptote most definitely *not* at zero. | 40aae592ac05b3006a14672467f6316b93efece88d435d37fa597abe45b5e444 | ['1994b01400244ea5b858f067c0077a69'] | @user972014 `w` is normal to `B` and `A` both - as I understand, that's a property of the cross product in non-degenerate cases. If you can provide an example where `w` wouldn't be "normal" - I'll certainly reconsider! A vector is normal to some other object, such as another vector or a plane, so you'd have to mention that - otherwise what you say has no useful meaning. And just to be explicit: a plane is uniquely normal to either of a pair of opposite vectors, and any vector on that plane will also be normal to both. An infinite set of unit vectors is normal to any given unit vector. |

And since we dont know these scientific terms, we let them add taxonomy terms to the list.
Slight difference however, we use the module Autocomplete Deluxe. Works like magic for us.
You are able to see what taxonomy terms are already available by clicking into the text area.
And as you type a taxonomy term, you will see what other terms are similar. If a tag is new, it will be added. one thing, dont allow them to delete your tags. We learned this the hard way.
See the image below on what it looks like as you add a tag.
Above is what you will see when you are adding the taxonomy field in your content type, this is after you install the Autocomplete Deluxe module

Actually, I am interested to know what will happen below 9.5 MHz for the mentioned value of inductor and capacitors. If it is a single L-C low pass filter I can understand it will attenuate high-frequency components over 9.5 MHz. However, I am not clear about how the chain L-C network will work below 9.5 MHz in this case. If I need to pass a signal from generator with a frequency below 9.5 MHz to a 50-ohm antenna what parameters should I consider to modify? I need to keep the L-C ladder network which is a constraint for me while ensuring signal transfer to load/antenna |

string[] attendence;
private void setAttendence(List<String> studentList) {
int j=1;
for(String attList: studentList){
if(attList != null){
attendence[j]= attList; // getting null pointer exception
}
j++;
}
}
public static void main(String[] args) {
String sampleInput = "S0032124, Tan ah cat, ICT310-FT02, no, yes, yes, no, yes, yes, yes, yes, no, yes, 43, 55, 12, 53";

for (String s : sampleInput.split(",")) {
studentList.add(s);
}
attendence = new string[36];
newStudent.setAttendence(studentList.subList(3, 12));
}
Otherwise you can not reach a value from attendence because it is just a pointer indicates null.
If you are familliar with lower level programming languages, arrays are pointers and they need to show beginning of allocated memory space. By saying new string[n] you allocate n*sizeof(string) bytes memory space. So if you say attendence[1] you will reach location of &attendence + sizeof(string).
By the way string is a char array so you actually get pointer of pointer. I mean sizeof(string) = 1 word..

Stream functions are used for two dimensional fluid velocity fields, where their is a zero component for the fluid velocity in the third spatial dimension.
According to a possibly less than accessible reference, that I have found, ANY two dimensional solenoidal flow field $\mathbf{u}$ can be derived from a scalar stream function $\psi$.
For a two dimensional solenoidal flow $\mathbf{u}$ which hence obeys ,
\begin{align}
\mathbf{\nabla\cdot u}&= 0\\
\text{or } \frac {\partial u_1 } {\partial x } + \frac{\partial u_2 } { \partial y }&=0
\end{align}
we can have $\mathbf{u}$ given in terms of a stream function $\psi$, as
\begin{align}
u_1&= \frac {\partial \psi } {\partial y } \\
u_2&= -\frac{\partial \psi } { \partial x }
\end{align}
For the following quote, see Reference 1 ( a margin note on pg.15 )
it can be shown that the equation $\mathbf{\nabla\cdot u= 0}$
guarantees the existence of such a $\psi$

The route itself works fine.
I'm currently trying to define a readLock=changed strategy to skip files which are being written by another process, which works fine too.
The problem is, when a file gets skipped due to readLock, it seems that the batch size is not updated, and hence the onCompletion method of the aggregator is never called resulting in an dead route.
Shouldn't camel check the readLock before calculating the size of the batch? is there any way to achieve this or any equivalent solution?

PROS: as much definition and resolution your monitor can handle, low memory usage
CONS: read rate from disk is fairly large and could lead to low frame rate.

Then how would you prefix a boolean such as "myButton.shouldShow"?
I feel indeed that it's a little bit weird so I was hoping to find another solution.

> levels(AcademicData$JobAfter18)
[1] "No" "Yes, one job" "Yes, two jobs" "Yes, more than two jobs"
This variable has these 4 factor levels when viewed here. However, in the summary of the fit, it comes up as follows:
AcademicData$JobAfter18.L 34.<PHONE_NUMBER>.857406 1.005 0.31725
AcademicData$JobAfter18.Q -43.296277 20.763852 -<PHONE_NUMBER> *

Where are the L,Q, and C coming from, and what do they mean? I realize that factor variabels will include n-1 factor levels in the output, as the one not included is the baseline to which the others are compared. I am just not following why the levels are coming up with these letters rather than being written out, as they are for other variables, such as seen here with the "Sex" factor variable, which has levels "Male" and "Female":
AcademicData$SexMale 19.421651 12.331565 1.575 0.11863

My application is mainly razor-pages organized into areas eg. Admin, Sales, etc. I am able to successfully use a blazor component if I put it at the root of the application, however, if I move the component to an RCL I can access the component but it is not responsive (clicking the button for the counter example does not increment the count).
I want to be able to go localhost/Admin/RazorPageContainingBlazorComponent or localhost/Sales/AnotherRazorPageContainingBlazorComponent
I get this error in chrome dev tools:
'''
Error: Failed to complete negotiation with the server: Error
https://localhost:5000/myfeature/_blazor/negotiate 404
'''
I believe this is caused by the signalR hub being mapped to https://localhost:5000/, but I not sure how to add additional blazor hub mappings or how to change blazor.server.js to to use the root hub.

Adding the code below to you're layout file configures the signalR hub to use an absolute path instead of a relative path.
<script src="~/_framework/blazor.server.js" autostart="false"></script>
<script>
Blazor.start({
configureSignalR: function (builder) {
builder.withUrl("/_blazor");
}
});
</script>
This allows razor components to be used directly in a razor class library, using area routing.

If you don't like all the frames stuff in Flash, you can create a single frame app and then manage everything from your custom AS classes.
I'm also a .NET developer, and I had no trouble learning AS3.0. Of course, one week is not enough to become an expert (it takes years to become an expert in any field). But if you simply need to create video or mp3 players, create drag and drop basic games/apps to add to an ASP.NET page, it's worth spending 20 or 30 hours on AS3. There are great video trainings out there . Seven or 8 hours training should take the 20 to 30 hours I mentioned. I went for AS3.0 a few years ago, rather than SL, simply because everybody has Flash plugin installed.
AS3.0 is typed (simple types like Number, String etc), but at least it's typed. There are plenty of functions, classes and methods allowing to implement hit tests, drag/drop, event listening (mouse events, keyboard events etc). Really cool and fun language.
Take care.

Now, as we know angles can be expressed in degree as well as radians. When in any equations we use angles in degree what we get is degree related value. Whereas radians outputs only number. There is no unit to attach with the answer. Lets take an example:-
$f(x) = \frac {\sin x}{x}$ , for $x \in \mathbb R$ thereby $f(x)\in\mathbb R$
Now if we take $x = 30^\circ $.
The answer is $f(30^\circ)=0.0167\ degree^-1$
Now if we take $x=30\ radians\ or\ only\ 30$.
The answer is $f(30)=-0.988$
The reason behind it is we assume radians as unit less, calculations using radians give pure numbers. But with degree we have to associate it with the answer. Another prominent Example would be Angular Velocity.
$V = \dot \theta = \frac{d\theta}{dt} $
If we used $degrees\ as\ unit\ of\ \theta,\ then\ the\ unit\ of\ V\ is\ degree.s^-1, But\ if\ radians\ is\ used\ then\ radians.s^-1\ or \ simply\ s^-1 $
And also the radians is defined as:
$1\ radians$ is defined as the angles subtended by an arc such that the arc length is same as the radius.
As we can see its a ratio, an unit less substance.

However, it looks like a HashMap's capacity is always a power of 2 (even specifying the capacity in the constructor results in a call to Collections.roundUpToPowerOfTwo(capacity)), so notating it in the form 1 << x ensures this restriction trivially, even if you were to change x. the other forms would be easier to mess up when changing if you weren't aware of the restriction

The first step is to use the development versions of the libraries, in order to get better error messages. Use https://cdnjs.cloudflare.com/ajax/libs/react/15.4.1/react-with-addons.js instead of https://cdnjs.cloudflare.com/ajax/libs/react/15.4.1/react-with-addons.min.js.
Second, loading several versions of React can cause the issue your are having. Remove https://cdnjs.cloudflare.com/ajax/libs/react/<PHONE_NUMBER>/umd/react.production.min.js from the list of external scripts you are loading.
Thirdly, there is a typo when you specify the leave timeout of the animation. You have written transtionLeaveTimeout, where it should be transitionLeaveTimeout. With this type, the transition library will complain about a missing property.
This CodePen summarizes the changes you need to make.

This is, can I determine all of its sides and all of its angles with just this two sides?
Now, obviously I can determine all of the triangle's sides using <PERSON>'s theorem. But I'm struggling with the angles. I am supposed to use trigonometry, so to find the angle $\beta$ opposing the side $b$ I do this:
$$ \tan{\beta} = \frac{Op. Leg}{Adj. Leg} = \frac{b}{a} = \frac{5,5}{3,5} = 1,5714 \dots$$
Then I would do
$$ \beta = \tan^{-1} {\left( \tan{\beta} \right)} = \tan^{-1} {\left( 1,5714 \dots \right)} \approx 57,53^{\circ}.$$
The problem is that this last step was done using a calculator, which is not allowed by my professor. So my question is this: is there a way to obtain the angles of this triangle without the aid of a calculator?

There are sequences a simple state machine can detect which your approach cannot. For example, a 1, followed by any even number of 0s, followed by a 1.
Your approach could detect 1001, 100001, 10000001, but it can't do the general case. This is because you can only examine a finite amount of history. While you can (at a cost) make that amount as large as you want, it's still finite.
