Q: how inadvertently adding UTF8 format while copy paste? I have a string with non uft8 format
$str = Processing’s;
following json_encode works fine because i'm copying and pasting code to my editor
$str = Processing’s;
echo json_encode($str);
output:
Processing\u2019s"
if i retrive the same string Processing’s from DB and do json_encode it returns NULL because of it is non UTF8 string.
How when I copy paste code works like UTF8 encoded string? what happens when I copy and Paste the codes?

Q: Check if users are a member of an AD group - Powershell i have a txt file with a list of usernames and I want to check if these users are a member of a specific AD-group. If they aren't a member of this group, their username has to be written in a csv file. So the output should be a csv file with all usernames who are not in the specified AD-group.
I always get the error "A connection to the directory on which to process the request was unavailable. This is likely a transient condition".The error is reproduced when implementing a workflow that triggers up to 20 powershell sessions to run, each importing the Active Directory module to create a connection with AD.
This is my short script:
$userlist = get-content -Path "C:\Temp\users.txt"
$group = "group_xy"
$result = foreach ($user in $userlist)
{
$groupmembers = Get-ADgroup -Filter {Name -eq $group}|Get-ADGroupMember
if ($groupmembers.samaccountname -notmatch $users){
[PSCustomObject]@{
Name = $user
Group = $group
Member = 'False'
}
}
}
$result |Export-csv "C:\Temp\Result.csv" -NoTypeInformation
How can I solve this?
BR
A: if ($groupmembers.samaccountname -notmatch $users) {
Should be
if ($groupmembers.samaccountname -notmatch $user) {
Since you never define $users I think this is the error

Q: Null when sharing data between Activity and Fragment I got a problem that I can't share a RxBleClient between MainActivity and Fragments.
I pass a instance of RxBleClient to MyViewModel, and while trying to receive from ViewModel in Fragment it is just a Null. Fragment is a part of ViewPager2. Here is how I did this:
View Model code:
public class MyViewModel extends ViewModel {
private MutableLiveData<RxBleClient> rxBleClient = new MutableLiveData<RxBleClient>();
public MyViewModel() {
}
public void setRxBleClient(RxBleClient item) {
rxBleClient.setValue(item);
}
public LiveData<RxBleClient> getRxBleClient() {
return rxBleClient;
}
}
MainActivity:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MyViewModel model = new ViewModelProvider(this).get(MyViewModel.class);
// Turn on Bluetooth
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
int REQUEST_ENABLE_BT = 1;
this.startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
// pass instance of RxBleClient to ViewModel
rxBleClient = RxBleClient.create(getApplicationContext());
model.setRxBleClient(rxBleClient);
// bind
ButterKnife.bind(this);
// rest of code
Fragment code:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_connection_list, container, false);
scanResultList = new ArrayList<ScanResult>(0);
// Set the adapter
if (view instanceof RecyclerView) {
Context context = view.getContext();
RecyclerView recyclerView = (RecyclerView) view;
if (mColumnCount <= 1) {
recyclerView.setLayoutManager(new LinearLayoutManager(context));
} else {
recyclerView.setLayoutManager(new GridLayoutManager(context, mColumnCount));
}
recyclerView.setAdapter(new MyConnectionRecyclerViewAdapter(scanResultList));
}
// get View Model
myViewModel = new ViewModelProvider(getActivity()).get(MyViewModel.class);
myViewModel.getRxBleClient().observe(getViewLifecycleOwner(), client -> {
this.rxBleClient = client; // HERE IS NULL
});
return view;
}
Where did I make mistake?
First edit:
This is my only one Activity, yet. This Activity is hosting ViewPager2:
// FRAGMENT ADAPTER
fragmentStateAdapter = new ViewPager2FragmentStateAdapter(getSupportFragmentManager(), getLifecycle());
viewPager2 = findViewById(R.id.pager);
viewPager2.setAdapter(fragmentStateAdapter);
// TOP BAR
final String tabTitles[] = {"Debugging", "Bluetooth", "Video"};
final @DrawableRes int tabDrawable[] = {R.drawable.ic_bug_report_24px, R.drawable.ic_bluetooth_24px, R.drawable.ic_videocam_24px};
tabLayout = findViewById(R.id.tab_layout);
new TabLayoutMediator(tabLayout, viewPager2,
(tab, position) -> tab.setText(tabTitles[position]).setIcon(tabDrawable[position])
).attach();

Q: Use config.py file in other directories of my poject My project's structure is:
My_Project:
├── scripts
│ ├── script.py
├── _main_config
│ ├── config.py
I'm trying to call from script.py file the config.py file in main_config. I'm working with sagemaker studio so currently my project is not a module.
First I added init.py files to both the main project dir and to scripts dir as well.
I saw that i can use the following code:
import sys
sys.path.append('/root/My_Project/main_config')
from main_config.config import BehConfig
BehConfig is a simple class i created in the config.py file:
class BehConfig:
x = 'test'
y = ['test1', 'test2']
When I tried to print both x and y i got the correct values. When I tried to modify the config.py file and add for instance, a value for the list y, when i ran the print command i still got the previous output without the value that i added.
Does anyone know why it's not working?
My guess is that it has to do with the sys.path.append above the import but i was unable to fix the issue.
Thank you for your help!

A: Your explain plan that you gave:
id , select_type , table , type , possible_keys , key , key_len , ref , rows , Extra
1 , SIMPLE , a , ref , systemId idx_time) , systemId , 14 , const , 735310 , Using where
1 , SIMPLE , b , ref , PRIMARY , PRIMARY , 66 , gwreports2.a.msgId , 2270405 ,
1 , SIMPLE , c , ref , PRIMARY , PRIMARY , 66 , gwreports2.a.msgId , 2238701 ,
shows that you are hitting: 735310 * 2270405 * 2238701 = 3T rows!!!!!!
Effectively your not using your indexes to their fullest potential.
How to interpret your 'explain plan':
For every row in table 'a' (735310 ), you hit table 'b' 2270405 times.
For every row you hit in table 'b', you hit table 'c' 2238701 times.
As you can see, this is an exponential problem.
Yes, the 8MB of InnoDb Buffer space is small, but getting your explain plan down to xxxx * 1 * 1 will result in incredible speeds, even for 8MB of Buffer Space.
Given your Query:
SELECT a.msgId,a.senderId,a.destination,a.inTime,a.status as InStatus,b.status as SubStatus,c.deliverTime,substr(c.receipt,82,7) as DlvStatus
FROM inserted_history a
LEFT JOIN submitted_history b ON b.msgId = a.msgId -- USES 1 column of PK
LEFT JOIN delivered_history c ON a.msgId = c.msgId -- USES 1 column of PK
WHERE a.inTime BETWEEN '2010-08-10 00:00:00' AND '2010-08-010 23:59:59' -- NO key
AND a.systemId='ND_arber' -- Uses non-unique PK
Here are the problems I see:
A) Your _history tables are partitioned on the columns with 'Timestamp' datatype, YET you are NOT those columns in your JOIN/WHERE criteria. The engine must hit EVERY partition without that information.
B) Access to submitted_history and delivered_history is using only 1 column of a 2-column PK. You are only getting partial benefit of the PK. Can you get more columns to be part of the JOIN? You must get the # of rows found for this table as close to '1' as possible.
C) msgID = varchar(64) and this is the 1st column of the PK for each table. Your Keys on each table are ** HUGE **!!
- Try to reduce the size of columns for the PK, or use different columns.
Your data patterns of the other keys shows that you have LOTS of disk/ram space tied up in non-PK keys.
Question 1) What does "Show Indexes FROM " (Link) for each of the tables report?? The column 'Cardinality' will show you how effective each of your keys really are. The smaller the cardinality is, the WORST/Less effective that index is. You want cardinality as close to "total rows" as possible for ideal performance.
Question 2) Can you re-factor the SQL such that the JOIN'd columns of each table are those with the highest cardinality for that table?
Question 3) Is the columns of 'timestamp' datatype really the best column for the partitioning? If your access patterns always use 'msgId', and msgId is the 1st column of the PK, then .
Question 4) Is msgId unique? My guess is yes, and the 2nd column of the PK is not really necessary.
Read up on Optimizing SQL (Link) and have the index cardinality reports of your tables. This is the path to figure out how to optimize an query. You want the 'rows' of the explain plan to be N * 1 * 1.
SIDE NOTE:InnoDb & MyISAM engines does NOT automatically update table cardinality for non-unique columns, the DBA needs to manually run 'Analyze Table' periodically to ensure its accuracy.
Good Luck.
A: Would it be possible to alter the index of inserted_history,
systemId (systemId)
to be
systemId (systemId, inTime). Or add an additional index
My logic being that this should help to speed up the selection of the inserted_history (a) rows which forms the basis of the join.
The where clause "where a.inTime between '2010-08-10 00:00:00' and '2010-08-010 23:59:59' and a.systemId='ND_arber'" would all be selectable by index. At present, rows are selectable by systemId but then all those rows need to be scanned for the time.
Just as a matter of interest, how many records would there be (on average) for each system id. Also as msgid is not unique on its own, how many records (on average) in the other tables will have teh same msgid.
A: Main Idea
Are you using InnoDB? It looks like your buffer pool is only 8MB. That could easily be the problem, you're dealing with a lot of data and InnoDB doesn't have much memory. Can you bump the innodb_buffer_pool_size up? You'll have to restart MySQL, but I'm betting that would make a HUGE difference, even if you only give it 256 or 512MB.
Update: I see your storage engine and table format seem to default to MyISAM, so unless you specified otherwise this wouldn't apply. I wonder if the myisam_sort_buffer_size would help? We don't use MyISAM so I'm not familiar with tuning it.
Random Thought
I wonder if having having the primary key be alphanumeric (especially VARCHAR) has anything to do with it. I remember we had problems with performance on non-numeric primary keys, but that database dated from 4.0 or 4.1, so that may not apply (or ever have been true).
Secondary Idea
After the memory thing above, my best guess would be to give MySQL more hints. When I have a query that's running slow, I often find giving it more information helps it out. You have messageId/time indexes on each table. Maybe something more like this would work better:
select a.msgId,a.senderId,a.destination,a.inTime,a.status as InStatus,
b.status as SubStatus,c.deliverTime,substr(c.receipt,82,7) as DlvStatus
from inserted_history a left join submitted_history b on b.msgId = a.msgId
left join delivered_history c on a.msgId = c.msgId
where a.inTime between '2010-08-10 00:00:00' and '2010-08-010 23:59:59'
and a.systemId='ND_arber' AND c.inTime between b.inTime >= a.inTime
and c.inTime >= b.inTime
I'm guessing things get inserted into A, then B, then C. If you have better limits (say when something goes in A, it's always sent out and submitted within one day) add that information could help.
I wonder about this both because I've seen it help my query performance in some situations, but also because you have the data partitioned on the datetime. That may help the optimizer.
My other suggestion would be to run your query for a short amount of time, say 10 minutes instead of a full day, and make sure the results are right. Then try 30. Increase it and see when it falls off into "come back tomorrow" territory. That may tell you something.

Q: What is the preferred way to undo a `svn switch` with svn 1.7? Switching below the root of a project, svn switches that subdirectory only. Prior svn 1.7 one could simply delete that directory and run an update.
But now with svn 1.7, it doesn't store svn-information per directory. How can I undo the effect of the switch?
extra: apart the command line client, can it be done via TortoiseSVN? :) on win32
note this question was already asked, but for svn < 1.7 which is a quite different situation

Q: A simple model in Winbugs but it says "This chain contains uninitialized variables" I have some simple time to event data, no covariates. I was trying to fit a Weibull distribution to it. So I have the following code. Everything looks good until I load my initials. It says "this chain contains uninitialized variables". But I don't understand. I think Weibull dist only has 2 parameters, and I already specified them all. Could you please advise? Thanks!
model
{
for(i in 1 : N) {
t[i] ~ dweib(r, mu)I(t.cen[i],)
}
mu ~ dexp(0.001)
r ~ dexp(0.001)
}
# Data
list(
t.cen=c(0,3.91,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,21.95,23.98,33.08),
t=c(2.34,NA,5.16,5.63,6.17,6.8,7.03,8.05,8.13,8.36,8.83,10.16,
10.55,10.94,11.48,11.95,13.05,13.59,16.02,20.08,NA,NA,
NA),
N=23
)
# Initial values
list(
r=3,mu=3
)
A: The other uninitialised variables are the missing (NA) values in the vector of t. Remember that the BUGS language makes no distinction between data and parameters, and that supplying something as data with the value NA is equivalent to not supplying it as data.

Q: Solving Matrix elements by using while iteration in Matlab I have a known 5X6 sized M matrix, and a 6x1 sized K matrix which its 4 elements unknowns and two knowns. P matrix obtained by multiplication of these two matrices and has different 5 elements all which function of an x variable. Altogether, there are 5 equations and 5 unknowns (four from the K, and one from the P(which is x))
M[5X6]*K[6X1]=P[5X1]
P=[constant*x, constant2*x, constant3*x, constant4*x, constant5*x)
How can I obtain a while iteration in Matlab to solve these 5 unknowns? Is this possible in Matlab with the while or for loop? `

Q: truncate git repository keepinng regular snapshots I want to keep track on a 500kb json text that changes its content minutely. I would like to use git, so I can use git pull on another server to download the latest version of that file without the problem, that the file could change during download and I also want to have a versioning of that file for the last months/years this way at the same time.
I thought of creating a git repository where I commit every file change, but I noticed, after some days, this repository gets the size of many GB (even with git gc because there changes so much in the file)
I could truncate the git regularly to a particular depth but that is not what I need. I need the information, how the file looked like a week ago, a month ago, a year ago. although I don't need as many commits the longer in the past it is.
Is this even possible with git and some bash magic? I am fine with deleting and recreating the repository and using --amend in that git
Or would you suggest another solution?
A: There is at least one way to do this; I'll outline an approach below. First a few things to think about:
Depending on the nature of the changes that occur, you might want to see if frequent packing of the database might help; git is pretty good at avoiding wasted space (for text files, at least).
Of course with the commit load you describe - 1440 commits per day, give or take? - the history will tend to grow. Still, unless the changes are dramatic on every commit, it seems like it could be made better than "many GB in a few days"; and maybe you'd reach a level where a compromise archiving strategy would become practical.
It's always worth thinking, too, about whether "all the data I need to keep" is bigger than "all the data I need regular access to"; because then you can consider whether some of the data should be preserved in archive repos, possibly on backup media of some form, rather than as part of the live repo.
And, as you allude in your question, you might want to consider whether git is the best tool for the job. Your described usage doesn't use most of git's capabilities; nor does it exercise the features that really make git excel. And conversely, other tools might make it easier to progressively thin out the history.
But with all of that said, you still might reach the decision to start with "per minute" data, then eventually drop it to "per hour", and maybe still later reduce to *per week".
(I'd discourage defining too many levels of granularity; the most "bang for your buck" will come with discarding sub-hourly snapshots. Hour->day would be borderline, day->week would probably be wasteful. If you get down to weekly, that's surely sparse enough...)
So when some data "ages out", what to do? I suggest that you could use some combination of rebasing (and/or related operations), depth limits, and replacements (depending on your needs). Depending on how you combine these, you could keep the illusion of a seamless history without changing the SHA ID of any "current" commit. (With more complex techniques, you could even arrange to never change a SHA ID; but this is noticeably harder and will reduce the space savings somewhat.)
So in the following diagrams, there is a root commit identified as 'O'. Subsequent commits (the minutely changes) are identified by a letter and a number. The letter indicates the day the commit was created, the numbers sequentially mark off minutes.
You create your initial commit and place branches on it for each granularity of history you'll eventually use. (As changes accumulate each minute, they'll just go on master.)
O <--(master)(hourly)(weekly)
After a couple days you have
O <-(hourly)(weekly)
\
A1 - A2 - A3 - ... - A1439 - A1440 - B1 - B2 - ... - B1439 - B1440 - C1 <--(master)
And maybe you've decided that at midnight, any sub-hour snapshot that's 24 hours old can be discarded.
So as day C starts, the A snapshots are older than 24 hours and should be reduced to hourly snapshots. First we must create the hourly snapshots
git checkout hourly
git merge --squash A60
git commit -m 'Day A 1-60'
git merge --squash A120
git commit -m 'Day A 61-120'
...
And this gives you
O <-(weekly)
|\
| A60' - A120' - ... - A1380' - A1440' <-(hourly)
\
A1 - A2 - A3 - ... - A1439 - A1440 - B1 - B2 - ... - B1439 - B1440 - C1 <--(master)
Here A1440' is a rewrite of A1440, but with a different parentage (such that its direct parent is "an hour ago" instead of "a minute ago").
Next, to make the history seamless you would have B1 identify A1440' as its parent. If you don't care about changing the SHA ID of every commit (including current ones), a rebase will work
git rebase --onto A1440' A1440 master
Or in this case (since the TREEs at A1440 and A1440' are the same) it would be equivalent to re-parent B1 - see the git filter-branch docs for details of that approach. Either way you would end up with
O <-(weekly)
|\
| A60' - A120' - ... - A1380' - A1440' <-(hourly)
| \
| B1' - B2' - ... - B1439' - B1440' - C1' <-(master)
\
A1 - A2 - A3 - ... - A1439 - A1440 - B1 - B2 - ... - B1439 - B1440 - C1
Note that even though the granularity of changes in the B and C commits is unchanged, these are still "rewritten" commits (hence the ' notation); and in fact the original commits have not yet been physically deleted. They are unreachable, though, so they'll eventually be cleaned up by gc; if it's an issue, you can expedite this by discarding reflogs that are more than 24 hours old and then manually running gc.
Alternatively, if you want to preserve SHA ID's for the B and C commits, you could use git replace.
git replace A1440 A1440'
This has a number of drawbacks, though. There are a few known quirks with replacements. Also in this scenario the original commits are not unreachable (even though they aren't shown by default); you would have to shallow the master branch to get rid of them. The simplest way to shallow a branch is to clone the repo, but then you have to jump through extra hoops to propagate the replacement refs. So this is an option if you never want the master ref to "realize" it's moving in an abnormal way, but not as simple.

Q: Calculate How Many Overlapping Dates There Are Within Multiple Date Ranges I need to be able to calculate the number of days when someone was taking at least 1 drug from Class A and 1 drug from Class B.
One of the biggest issues I am encountering is that prescriptions for the same Drug Class may overlap each other and when they are joined to Class B prescriptions I end up double counting days.
For example, between 01/01/21 and 06/30/21, what's the total number of days for each individual where they took a drug from Class A and from Class B
I have fake data below as an example.

PS - I am working in Oracle SQL Developer
A: A relatively simple approach is a brute-force approach. This splits the periods into days for each class. Then joins and aggregates to get the total:
with cte1(id, d, endd, class) as (
select id, startd, endd, class
from table1
union all
select id, d + interval '1' day, endd, class
from cte1
where d < endd
),
cte2(id, d, endd, class) as (
select id, startd, endd, class
from table2
union all
select id, d + interval '1' day, endd, class
from cte2 -- edit here
where d < endd
)
select cte1.id, count(*)
from cte1 join
cte2
on cte1.id = cte2.id and cte1.d = cte2.d
group by cte1.id;
Here is a db<>fiddle.

Q: Creating a completely custom pagination component for tabulator Is there any way with which we can create a custom pagination component for tabulator?
I don't want to :
*
*Add custom controls to the Footer. (Already Checked Footer docs)
*Put the pagination element in a custom container. (Already checked with Pagination docs)
Use case:
Suppose I want to use a third party paginator for it's theming and interactivity options. Is there a way by which I can just apply the pagination classes to it and it will work as expected ?
A: Tabulator is a modular system, you could easily either modify the existing pagination module, or create your own from scratch.
There is a guide to Building Your Own Module along with several Example Modules to show how things work in practice.
If you want a good starting point for the pagination module then why not start with the source code for the existing pagination module, which you can find Here

Q: Reshape a large matrix with missing values and multiple vars of interest I need to reorganize a large dataset into a specific format for further analysis. Right now the data are in long format, with multiple records through time for each point. I need to reshape the data so that each point has a single record, but it will add many new columns of the time-specific data. I’ve looked at previous similar posts but I need to ultimately convert several of the current variables into columns, and I can’t find an example of such. Is there a way to accomplish this in a single reshape, or will I have to do several and then concatenate the new columns back together? Another wrinkle before I post the example is that not all points were sampled at each time-step, so I need those values to show up as NA. For example, (see data below) SitePoint A1 was not sampled at all in 2012, SitePoint A10 was not sampled during the first round in 2012, but K83 was sampled all nine times.
mydatain <- structure(list(SitePoint = structure(c(1L, 1L, 1L, 1L, 1L, 1L,

The actual dataset is about 23656 records X 15 variables, so doing it by hand is likely to cause major headaches and potential for mistakes. Any help or suggestions are appreciated. If this has been answered elsewhere, apologies. I couldn’t find anything directly applicable; everything seemed to related to three columns and only one of those being extracted as new variables. Thanks.

A: dcast from the devel version of data.table i.e., v1.9.5 can cast multiple columns simultaneously. It can be installed from here.
library(data.table) ## v1.9.5+
dcast(setDT(mydatain), SitePoint~Year_Rotation,
value.var=c('MR_Fire', 'fire_seas', 'OptTSF'))
A: You can use reshape to change the structure of your dataframe from long to wide using the following code:
reshape(mydatain,timevar="Year_Rotation",idvar="SitePoint",direction="wide")

Q: Simple way to get Twitter users home feed Does anyone know a good way to, using oAuth, retrieve a users home feed (using PHP or JavaScript)? I've been searching the web (Google, YouTube and the Twitter website), but have not yet found a simple tutorial like developers.facebook.com has.
If you know of a good tutorial, or you have written some code that works, I'd be glad to see it. I would prefer the entire process, from authorizing a user to displaying their feed, but anything is better than what I have now.
Hoping for answers!
A: OAuth is method for authentication, you should use REST API provided by Twitter.
Please check this: https://dev.twitter.com/docs/api/1.1 (statuses/user_timeline)
Edit:
https://github.com/abraham/twitteroauth
Please check "Extended flow using example code" section, there's everything you want to know.
Just one note, if you have long-live access token (from your app dashboard, see oauth tab), you just pass token and token secret as third and fourth parameter when you create new instance of TwitterOAuth class, like this:
$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, OAUTH_TOKEN,
OAUTH_SECRET);

Q: Does MrBean module still automatically support dynamically implementing simple interfaces when deserializing? When converting from Jersey1 client to Jersey2 client (with jackson 2.8.6), I now get a mapping exception when trying to read my interface
WebTarget resource = helper.resource(path);
if(schedule != null) resource = resource.queryParam("schedule", schedule);
return resource.request().get(new GenericType<MyInterface>(){});
Caused by: javax.ws.rs.client.ResponseProcessingException: com.fasterxml.jackson.databind.JsonMappingException: Can not construct instance of com.mycompany.MyInterface: abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information
the old client code looked like this:
WebResource resource = helper.resource(path);
if(schedule != null) resource = resource.queryParam("schedule", schedule);
try
{
return resource.get(new GenericType<MyInterface>(){});
}
catch(UniformInterfaceException e)
{
throw new RuntimeException(e.getResponse().getEntity(String.class));
}
in both cases, all i did with the client object mapper was:
objectMapper.registerModule(new MrBeanModule());
is dynamic instantiation of interfaces gone now? If not, what additional configuration steps need to be performed to get it working?
(our dependencies are a bit of a mess, so i think i was using Jersey 1.6 with Jackson 1.9.8)
EDIT:
as another example of the previous behavior we relied upon, see http://www.cowtowncoder.com/blog/archives/2011/08/entry_459.html where there is a simple interface with no annotations
A: i think i found it after a lot of blood, sweat, and tears.
i found that the ObjectMapper i had configured was actually not the one that was being used.
Jersey1
clientConfig.getSingletons().add(new JacksonJsonProvider(objectMapper));
Client client = new Client(urlConnectionClientHandler, clientConfig);
JAXRS2 (what did not work)
clientConfig.register(new JacksonJsonProvider(objectMapper));
Client client = ClientBuilder.newClient(cc);
i found that the component creating the ObjectMapper that was ACTUALLY being used was a JacksonJaxbJsonProvider and that registering it with the ClientConfig did not work, but registering it on the client did.
JAXRS2 (what did work)
Client client = ClientBuilder.newClient(cc);
client.register(new JacksonJaxbJsonProvider(objectMapper, JacksonJaxbJsonProvider.DEFAULT_ANNOTATIONS));

Scilab cannot create Scilab Java Main-Class (we have not been able to find the main Scilab class. Check if the Scilab and thirdparty packages are available).
i tried reinstalling it and reinstalling java but still doesn't work
A: I have encountered the same problem. After googling I found out that this bug was fixed in Scilab 6.0.2.
You can download it here:
https://www.scilab.org/download/6.0.2
Current version of Scilab, that you can get from
sudo apt-get scilab
is 6.0.1 (for me scilab-cli was working, but GUI was not)
Currently Scilab 6.0.2 works in GUI mode and CLI under Ubuntu 18.04.4 LTS. XCOS works too.
It is a little bit laggy after start, but it might be my setup.

Q: How to delete old versions of tables in Delta Lake As I understand from documentation, delta lake allows to roll back or "time travel", as they say, to some specific version of a table. But how can I make sure that deleting data will actually delete it without creating a new version?
A: This can be implemented using vaccum of the Delta Lake and if the retention is set.

Q: How to get PowerShell to keep a command window open? When I run a program on PowerShell it opens a new window and before I can see the output, the window closes. How do I make it so PowerShell keeps this window open?
A: The OP seemed satisfied with the answer, but it doesn't keep the new window open after executing the program, which is what he seemed to be asking (and the answer I was looking for). So, after some more research, I came up with:
Start-Process cmd "/c `"your.exe & pause `""
A: I was solving a similar problem few weeks ago. If you don't want to use & (& '.\program.exe') then you can use start process and read the output by start process (where you read the output explicitly).
Just put this as separate PS1 file - for example (or to macro):
param (
$name,
$params
)
$process = New-Object System.Diagnostics.Process
$proInfo = New-Object System.Diagnostics.ProcessStartInfo
$proInfo.CreateNoWindow = $true
$proInfo.RedirectStandardOutput = $true
$proInfo.RedirectStandardError = $true
$proInfo.UseShellExecute = $false
$proInfo.FileName = $name
$proInfo.Arguments = $params
$process.StartInfo = $proInfo
#Register an Action for Error Output Data Received Event
Register-ObjectEvent -InputObject $process -EventName ErrorDataReceived -action {
foreach ($s in $EventArgs.data) { Write-Host $s -ForegroundColor Red }
} | Out-Null
#Register an Action for Standard Output Data Received Event
Register-ObjectEvent -InputObject $process -EventName OutputDataReceived -action {
foreach ($s in $EventArgs.data) { Write-Host $s -ForegroundColor Blue }
} | Out-Null
$process.Start() | Out-Null
$process.BeginOutputReadLine()
$process.BeginErrorReadLine()
$process.WaitForExit()
And then call it like:
.\startprocess.ps1 "c:\program.exe" "params"
You can also easily redirect output or implement some kind of timeout in case your application can freeze...
A: If the program is a batch file (.cmd or .bat extension) being launched with cmd /c foo.cmd command, simply change it to cmd /k foo.cmd and the program executes, but the prompt stays open.
If the program is not a batch file, wrap it in a batch file and add the pause command at the end of it. To wrap the program in a batch file, simply place the command in a text file and give it the .cmd extension. Then execute that instead of the exe.
A: Try doing:
start-process your.exe -NoNewWindow
Add a -Wait too if needed.
A: With Startprocess and in the $arguments scriptblock, you can put a Read-Host
$arguments = {
"Get-process"
"Hello"
Read-Host "Wait for a key to be pressed"
}
Start-Process powershell -Verb runAs -ArgumentList $arguments
A: pwsh -noe -c "echo 1"

Q: How to run jQuery before loading page? I have many images on site and some scripts on it. But scripts can run only after loading whole page. How to accelerate this?
A: $(document).ready(function() {
//code here
});
will run a script when the document structure is ready, but before all of the images have loaded.
if you want to run script before the document structure is ready, just put your code anywhere.
A: Sometimes if you only use $(document).ready(), there will be a flash of content.
To avoid the flash, you can hide the body with css then show it after the page is loaded.
*
*Add the line below to your CSS:
html { visibility:hidden; }
*And these to your JS:
$(document).ready(function() {
//your own JS code here
document.getElementsByTagName("html")[0].style.visibility = "visible";
});
Then the page will go from blank to showing all content when the page is loaded, no flash of content, no watching images load etc.
Inspired by this, thanks to the author.
A: Load the images after the page loads?
It may depends on what kind of jquery code you're trying to run--what specifically are you trying to do?
A: Use
$(document).ready(function() {
//code here
});
and put the jQuery-Script tags at the end of the document.
.ready fires when the DOM is ready (which does not mean that the images are already loaded).
A: If your JavaScript does any work on your Dom elements, then you have to wait until the page loads.
If you need to run the scripts before the image are loaded, you can always lazy load the images. That way you don't have to wait for the images to load.
Lazy loading is basically loading the images through JavaScript, so you can control when they load.

Q: Adding feature with duplicate ID to Vector source Right now, if I add two features with the same id to a Vector source, it seems like the second one is discarded. Is there anyway to force OpenLayers to replace features with the existing ids?
A: var features=layer.getSource().getFeatures();
for(var i=0;i<features.length;i++){
if(features[i].get('id')==id){
layer.getSource().removeFeature(features[i]);
break;
}
}
}
or from @sox:
layer.getSource().removeFeature(layer.getSource().getFeatureById(id));

Q: What is the best strategy to update web project from JSF 1.1 to JSF 2.x? We have a large - and quite old - project using JSF 1.1 (specifically the MyFaces implementation) with JSP as view technology. Right now we want to upgrade the used JSF version, view technology and taglibs in use. Migrating from JSF 1.2 to JSF 2.0 gave some idea of the woes we are likely to encounter.
I am new to JSF but I do understand that Facelets are only supported since JSF 2.x, so we need to update the JSF version before we can begin replacing JSPs with Facelets.
Currenty, we also use some old taglibs like Ajax4JSF and an old version of RichFaces, that - IIRC - is based on Ajax4JSF and of which one main feature is also to provide Ajax functionality and Ajax-enabled components to JSF. If I got this right, JSF 2.x supports Ajax functionality natively and therefor taglibs like Ajax2JSF aren't really needed anymore.
Since it seems that RichFaces' "life cycle" has finished last year (according to wikipedia), this also seems to be a good opportunity to also replace RichFaces with PrimeFaces, which seems to be still in active development and gets recommended quite often. I am not sure, though, if this replacement makes sense or if these two component libraries even offer similar components or if they aim two provide two totally different sets of components and this replacement is a bad idea to begin with.
One way or the other, I'd like to know in which order these 3 steps would make the most sense. Since Facelets require JSF 2.x and current versions of modern taglibs also only seem to work with new JSF versions, I assume updating JSF has to be done first, but concerning the replacement of JSPs with Facelets and of RichFaces/Ajax4JSF with PrimeFaces, in which order should these two be done?
My guess is that current taglibs might also depend on Facelets so perhaps this order makes the most sense?
*
*JSF 1.1 => JSF 2.x
*JSP => Facelets
*RichFaces => PrimeFaces
A: To answer my own question: After working on this upgrade for some time and running into a few dead ends, for me the following order of steps has turned out best:
*
*Upgrade JSF implementation (in my case: from MyFaces 1.1 to MyFaces 2.2.12)
*Replace JSP files with Facelets and comment out all occurences of tags from unsupported tag libraries (some functionality will be lost until the migration is completed, but this way I have to migrate those taglibs just once - to use them in Facelets - and not twice (once for use in JSPs with JSF 2, and then for use in Facelets))
*Replace and update unsupported and outdated tag libs

Q: Unable to set custom colors inside ExpandableListView I'm an Android newbie.
I'm trying to set custom colors inside an ExpandableListView adapter. I have defined my colors in colors.xml, but I'm unable to use them in my adapter. I get an error "The method getResources() is undefined for the type ExpandableListAdapter"
The function expects an int. I've tried to pass my result from getResources in, but, it does'nt work. I've also tried to pass in a hex value, but it does'nt change anything.
How can I use my custom colors in my code?
public View getGroupView(int groupPosition, boolean arg1, View convertView,
ViewGroup arg3) {
int n = 0;
String laptopName = (String) getGroup(groupPosition);
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.group_item, null);
}
TextView item = (TextView) convertView.findViewById(R.id.demo);
item.setTypeface(null, Typeface.BOLD);
item.setText(laptopName);
convertView.setBackgroundColor(getResources().getColor(R.color.purple));
return convertView;
}
Thanks guys, the following snippet works
this.context = (Activity) context;
convertView.setBackgroundColor(this.context.getResources().getColor(R.color.purple));
A: As loulou8284 mentioned you can put it in your XML, or if it is fixed, define it with Color.rgb(), but to make your code running you need to get the reference to your Context as your class is not declared inside a context-class:
convertView.setBackgroundColor(getContext().getResources().getColor(R.color.purple));
A: Assuming you have a context instance somewhere in the adapter instead of this
convertView.setBackgroundColor(getResources().getColor(R.color.purple));
it should be this
convertView.setBackgroundColor((your context).getResources().getColor(R.color.purple));
and if you don't have a reference to the context just pass it in to the adapter constructor
A: You can declare the color in you .xml file ( in your item xml file )
A: Use setBackgroundResource() rather than setBackgroundColor()
setBackgroundResource() takes an integer resource index as parameter, and load whatever resource that index points to (for example; a drawable, a string or in your case a color).
setBackgroundColor(), however takes an integer representing a color. That is, not a color-resource, but a direct, hexadecimal, rgba value (0xAARRGGBB).

I want to also be able to calculate a fixed component so that i can add say $100 to the tax calculated for every income above the first bracket of 18200.
I tried this but it adds $100 to all incomes below 18200 as well.
income_tax <-
function(income,
brackets = c(18200, 37000, 80000, 180000, Inf),
rates = c(0, .19, .325, .37, .45),
fixed = c(0,100,0,0,0)) {
sum(diff(c(0, pmin(income, brackets))) * rates + pmin(income, fixed))
}
any help on whatever obvious error i've made would be much appreciated!
A: How about this?
income_tax <- function(income,
brackets = c(18200, 37000, 80000, 180000, Inf),
rates = c(0, .19, .325, .37, .45),
fixed = c(0,100,0,0,0)) {
check <- diff(c(0,pmin(income, brackets)))
sum(check * rates + fixed * (check>0)) }
which gives,
income_tax(18200)
# [1] 0
income_tax(18201)
#[1] 100.19

Q: Docker Couchbase: Cannot connect to port 8091 using curl from within entrypoint script Running docker-machine version 0.5.0, Docker version 1.9.0 on OS X 10.11.1.
I've a Couchbase image of my own (not the official one). From inside the entrypoint script, I'm running some curl commands to configure the Couchbase server and to load sample data. Problem is, curl fails with error message Failed to connect to localhost port 8091: Connection refused.
I've tried 127.0.0.1, 0.0.0.0, localhost, all without any success. netstat shows that port 8091 on localhost is listening. If I later log on to the server using docker exec and run the same curl commands, those work! What am I missing?

curl -v -u Administrator:password -X POST http://127.0.0.1:8091/sampleBuckets/install -d '["travel-sample"]'
This configures the Couchbase server but still debugging how to bring Couchbase back in foreground.
Complete details at: https://github.com/arun-gupta/docker-images/tree/master/couchbase
A: It turns out that if I do the curls after restarting the server, those work. Go figure! That said, note that the REST API for installing sample buckets is undocumented as far as I know. arun-gupta's blog and his answer here are the only places where I saw any mention of a REST call for installing sample buckets. There's a python script available but that requires installing python-httplib2.
That said, arun-gupta's last curl statement may be improved upon as follows:
if [ -n "$SAMPLE_BUCKETS" ]; then
IFS=',' read -ra BUCKETS <<< "$SAMPLE_BUCKETS"
for bucket in "${BUCKETS[@]}"; do
printf "\n[INFO] Installing %s.\n" "$bucket"
curl -sSL -w "%{http_code} %{url_effective}\\n" -u $CB_USERNAME:$CB_PASSWORD --data-ascii '["'"$bucket"'"]' $ENDPOINT/sampleBuckets/install
done
fi
where SAMPLE_BUCKETS can be a comma-separated environment variable, possible values being combinations of gamesim-sample, beer-sample and travel-sample. The --data-ascii option keeps curl from choking on the dynamically created JSON.
Now if only there was an easy way to start the server in the foreground. :)

Q: How to query associations in Linq to Entity framework in .NET Ria Services I have just started with Linq and Linq to Entity Framewok. On top of that with the .NET Ria services.
My problem is that I have 2 tables Folder and Item with a many to many relationsship using a third "connection" table FolderItem like this:
(source: InsomniacGeek.com)
In the .NET RIA Service domain service, I want to create a method that returns all Items for a given FolderID.
In T-SQL , that would something like this:
SELECT * FROM Item i
INNER JOIN FolderItem fi ON fi.ItemID = i.ID
WHERE fi.FolderID = 123
My Linq knowledge is limited, but I want to do something like this:
public IQueryable<Item> GetItems(int folderID)
{
return this.Context.Items.Where(it => it.FolderItem.ID == folderID);
}
This is not the correct syntax, it gives this error:
Cannot convert lambda expression to
type 'string' because it is not a
delegate type
What is the correct way of doing this (with associations) ?
Can I user the .Include("FolderItem") somehow?
Please, method syntax only.
PS.
Here's how it would look like using a Query Expression:
public IQueryable<Item> GetItemsByFolderID(int folderID)
{
return from it in this.Context.Items
from fi in it.FolderItem
where fi.Folder.ID == folderID
select it;
}
The qeustion is, how would it look like using the Method Based Query Syntax?
A: Your GetItems looks fine to me. You could also do:
public IQueryable<Item> GetItems(int folderID)
{
return this.Context.FolderItems
.Where(fi => fi.ID == folderID)
.Select(fi => fi.Items);
}
Both should return the same thing.
A: You can have the parent entity contain the child entities. There are 2 things you have to do to do this:
1) Update your domain query to include the folder items and items:
return from x in Context.FolderItems
.Include("FolderItem")
.Include("FolderItem.Item")
where x.ID == folderID
select x
2) Update the metadata file so that the RIA service knows to return the associations to the client:
[MetadataTypeAttribute(typeof(FolderMetadata))]
public partial class Folder
{
internal sealed class FolderMetadata
{
...
[Include]
public FolderItem FolderItem;
}
}

Q: HTML::Entities::encode_entities_numeric: Convert hex output to decimal I am using HTML::Entities module to encode some special chars. Here is my sample code:
use HTML::Entities qw(encode_entities_numeric);
my $str = "some special chars like € ™ © ®";
encode_entities_numeric($str);
print $str;
Output: € ™ © ®
As output is in HTML numeric hex code of the char.
I want output in form of HTML numeric decimal value of the chars like € ™ © ®
Is there a way to do this in encode_entities_numeric()
A: HTML::Entities does the conversion in a little sub named num_entry. Redefine that to be whatever you want:
use utf8;
use HTML::Entities qw(encode_entities_numeric);
{
no warnings 'redefine';
sub HTML::Entities::num_entity { sprintf "&#%d;", ord($_[0]); }
}
my $str = "some special chars like € ™ © ®";
encode_entities_numeric($str);
print $str;
For what it's worth, this is the sort of thing Perl wants you to do. It's designed so that you can change things in this manner. It would be nicer if HTML::Entities were set up to allow derived classes, but it's not. Perl, recognizing that the world is messy like this, has ways for you to adjust that for what you need.
A: No, it's not configurable (because € and € are 100% equivalent in HTML).

Q: How to update a user's friends from facebook on my site? I have an app in Rails and I have it configured so that when a user logs into my app, a list of their facebook friends who have authorized my app is stored in my database so that I can display this info to the user.
But does anyone have any best practices for keeping this information up to date? For example, if user A and user B both use my app, and user A adds user B as a friend, how can I ensure that user B is displayed on user A's friend list?
I know that I could query facebook every time that I display a user's friends list but the main reason for storing a user's facebook friends in the database is to increase performance and prevent having to make this kind of call each time a user clicks through. Any ideas or best practices?
A: maybe have a scheduled task to update that information maybe every day or week?
Here is one gem for helping on that

and inside settings
MEDIA_ROOT = '/home/mridul/Desktop/Django/interim/pic/uploadpic/media'

and manually create media directory inside uploadpic directory.
A: It's not:
<form action="/upload/submit/" method="POST" encrypt="multipart/form-data">
it's
<form action="/upload/submit/" method="POST" enctype="multipart/form-data">
i.e. enctype not encrypt
As an aside, you should use a Form or ModelForm to do this, it will make your life much easier.

Q: SQL Server stored procedure or function has too many arguments specified, when trying to pass 2 arguments in C# I am trying to execute a stored procedure called getLastFeatureUpdate.
I will explain below the problem, step by step:
I have created a table in SQL like this:
CREATE TABLE testTable
(
DayTime INT NOT NULL, /*yyddhhmm, 1010102345*/
FeatureNbr SMALLINT NOT NULL,
Val FLOAT(53) NOT NULL
);
I have now created a stored procedure called getLastFeatureUpdate. Important to notice here is that I use 2 parameters @maxDateTime and @tableName, as those are different each time. So I will then pass in those 2 parameters in the C# code that follows in the end.
The stored procedure (if I remove @tableName text from the procedure and the C# code. Then the code does work to mention)
CREATE PROCEDURE getLastFeatureUpdate
@maxDateTime float(53) = 0,
@tableName text
AS
SELECT
test.FeatureNbr,
test.DayTime,
test.Val
FROM
@tableName test
WHERE
DayTime = (SELECT MAX(DayTime)
FROM @tableName
WHERE FeatureNbr = test.FeatureNbr --This is what you are missing
AND DayTime <= @maxDateTime) --10102248
The C# code where I want to return the data from testTable. Which are shown in: MessageBox.Show(d1 + "," + d2 + "," + d3);
But here is where I get the error:
Procedure or function getLastFeatureUpdate has too many arguments specified
Notice, that if I don't pass on the 2nd row here with @tableName, the code will work (I then have to remove @tableName as a parameter also in the stored procedure getLastFeatureUpdate)
cmd.Parameters.Add(new SqlParameter("@maxDateTime", 10102248));
cmd.Parameters.Add(new SqlParameter("@tableName", "testTable")); //If not using this parameter, the code will work
C# code:
void getLastFeatureUpdate()
{
using (SqlConnection conn = new SqlConnection(GetConnectionString()))
{
conn.Open();
// 1. create a command object identifying the stored procedure
SqlCommand cmd = new SqlCommand("getLastFeatureUpdate", conn);
// 2. set the command object so it knows to execute a stored procedure
cmd.CommandType = CommandType.StoredProcedure;
// 3. add parameter to command, which will be passed to the stored procedure
cmd.Parameters.Add(new SqlParameter("@maxDateTime", 10102248));
cmd.Parameters.Add(new SqlParameter("@tableName", "testTable")); //If not using this parameter, the code will work
// execute the command
using (SqlDataReader rdr = cmd.ExecuteReader())
{
// iterate through results, printing each to console
while (rdr.Read())
{
int v1 = (int)rdr["DayTime"];
int v2 = (Int16)rdr["FeatureNbr"];
double v3 = (double)rdr["Val"];
MessageBox.Show(v1 + "," + v2 + "," + v3);
}
}
}
}
static private string GetConnectionString()
{
return "Data Source=(LocalDB)\\MSSQLLocalDB;AttachDbFilename=C:\\Users\\andre\\source\\repos\\TestDatabaseCreation\\DatabaseTest.mdf;Integrated Security=True;Connect Timeout=30";
}
A: You cannot parameterize the table name in SQL Server, so: that SQL is invalid, and the CREATE PROC did not in fact run. What the contents of the old proc are: only you can know, but: it isn't the code shown. It was probably a dummy version you had at some point in development. Try typing:
exec sp_helptext getLastFeatureUpdate;
Specifically, the server should have told you:
Msg 1087, Level 16, State 1, Procedure getLastFeatureUpdate, Line 12 [Batch Start Line 0]
Must declare the table variable "@tableName".
Msg 1087, Level 16, State 1, Procedure getLastFeatureUpdate, Line 19 [Batch Start Line 0]
Must declare the table variable "@tableName".

how can i solve this problem ?
i can cimpile any gtkmm 2.4 code with this command : " g++ basic.cc -o basic pkg-config gtkmm-3.0 --cflags --libs "
and this command : " g++ basic.cc -o basic pkg-config gtkmm-2.4 --cflags --libs "
thanks
A: I think you hit this gtkmm bug, apparently triggered by more recent versions of GTK+, and now fixed:
https://bugzilla.gnome.org/show_bug.cgi?id=681323
I have asked Ubuntu to update their package, but they are usually slow about that if they do it at all:
https://bugs.launchpad.net/ubuntu/+source/gtkmm3.0/+bug/1046469
A: You might want to try reinstalling libgtkmm-3.0-dev. The code compiles fine for me but I get a Seg Fault. It does work when I change Gtk::ApplicationWindow to Gtk::Window.
A: there is nothing wrong with your install. that code is bad.
try it again, using
Gtk::Window window;
instead of the ApplicationWindow. When the GNOME documentation for a given class has a description of "TODO", that's a bad thing.

Q: is there any conditional annotation in JUnit to mark few test cases to be skipped? As far as I know to skip a test case the simplest thing to do is to remove the @Test annotation, but to do it over a large number of test cases is cumbersome. I was wondering if there is any annotation available in JUnit to turn off few test cases conditionally.
A: As other people put here @Ignore ignores a test.
If you want something conditional that look at the junit assumptions.
http://junit.sourceforge.net/javadoc/org/junit/Assume.html
This works by looking at a condition and only proceeding to run the test if that condition is satisfied. If the condition is false the test is effectively "ignored".
If you put this in a helper class and have it called from a number of your tests you can effectively use it in the way you want. Hope that helps.
A: You can use the @Ignore annotation which you can add to a single test or test class to deactivate it.
If you need something conditional, you will have to create a custom test runner that you can register using
@RunWith(YourCustomTestRunner.class)
You could use that to define a custom annotation which uses expression language or references a system property to check whether a test should be run. But such a beast doesn't exist out of the box.
A: Hard to know if it is the @Ignore annotation that you are looking for, or if you actually want to turn off certain JUnit tests conditionally. Turning off testcases conditionally is done using Assume.
You can read about assumptions in the release notes for junit 4.5
There's also a rather good thread here on stack over flow:
Conditionally ignoring tests in JUnit 4
A: If you use JUnit 4.x, just use @Ignore. See here

Q: Removing an item from a stack, whilst iterating over it, in android Usually, in java, to delete an item from a stack (or set) I would do something along the lines of:
Stack<Particle> particles = new Stack<Particle>();
int i = 0, ;
while(i < particles.size()) {
if(particles.elementAt(i).isAlive()) {
i ++;
} else {
particles.remove(i);
}
}
I've searched the android docs and googled quite a few times in an attempt to achieve the same results, but nothing seems to work. Can anyone help me here?
A: Try looping using an Iterator, since per Oracle Iterator.remove() is the only safe way
to remove an item from a Collection (including a Stack) during iteration.
From http://docs.oracle.com/javase/tutorial/collections/interfaces/collection.html
Note that Iterator.remove is the only safe way to modify a collection during iteration; the behavior is unspecified if the underlying collection is modified in any other way while the iteration is in progress.
So something like the following should work:
Stack<Particle> particles = new Stack<Particle>();
... // Add a bunch of particles
Iterator<Particle> iter = particles.iterator();
while (iter.hasNext()) {
Particle p = iter.next();
if (!p.isAlive()) {
iter.remove();
}
}
I've used this approach in a real Android app (OneBusAway Android - see code here), and it worked for me. Note that in the code for this app I also included a try/catch block in case the platform throws an exception, and in this case just iterate through a copy of the collection and then remove the item from the original collection.
For you, this would look like:
try {
... // above code using iterator.remove
} catch(UnsupportedOperationException e) {
Log.w(TAG, "Problem removing from stack using iterator: " + e);
// The platform apparently didn't like the efficient way to do this, so we'll just
// loop through a copy and remove what we don't want from the original
ArrayList<Particle> copy = new ArrayList<Particle>(particles);
for (Particle p : copy) {
if (!p.isAlive()) {
particles.remove(p);
}
}
}
This way you get the more efficient approach if the platform supports it, and if not you still have a backup.
A: Have you ever try this:
Stack<String> stack = new Stack<String>();
stack.push("S");
stack.push("d");
for (String s : stack){
stack.pop();
}

Q: "Event driven" static webpage updates I get that by the very nature of static web pages, their content is, well, "static". In a world though where it's becoming ever more popular to host static pages on a service like AWS S3 and run some cloud computing functionality through something like AWS Lambda, I was wondering if it was possible to update your static content when something were to change, making your sites less static.
Sure, you can send out Ajax calls every second or so to see if anything changed, but in my humble opinion, that seems stupid and not really like a viable option.
Say for instance I kick off a process from my static page that will write an entry into a key store database when the process completed. Is there a way to update the web page to let the user know the process has finished, without reloading the page?

Q: NSTextView / NSScrollView - A few questions to help me understand it's proper usage I have created a "notes" field designed to hold multiple paragraphs of text which I would like to store in a custom object. Originally, I just used an NSTextField as a temporary solution, but this does not allow me to scroll or have multiple paragraphs of text...
In IB I have placed a NSTextView (which seems to be wrapped inside an NSScrollView.) Upon execution of my program, seems to allow me to enter text in multiple paragraphs, scroll, etc. In short it LOOKS to be exactly what I want would like it to be. So far so good.
Now, I need to retrieve the data from this field and store it in my custom object. This is where I'm getting a bit lost within the developer documentation...
My goals are fairly straight forward:
*
*Allow users to type away in the box.
*Store the contents of the box into a variable (array, etc.) in my custom object when the user moves to another field, leaving the notes field.
*Display the users stored text in the text box next time the record is viewed.
Second, is there a simple way to retrieve and store the data into a "notes" variable in my custom object (such as an NSString object? I would think having multiple would exclude an NSString object as an option here, but maybe I'm wrong) or am I getting into a more complex area here (such as having to store it in an array of NSString objects, etc.)?
Any help would be appreciated!
A: You can get the data using -string, defined by NSText (e.g. NSString *savedString = [aTextView string])
Your save code can be put in your NSTextDelegate (read, delegate of the NSTextView, because it's the immediate superclass), in – textDidEndEditing: which will be called, well, when editing is finished (e.g. when the user clicks outside the view) or one of the other methods.
Then to reload the saved string if you emptied the text view or something, use [textView setString:savedString] before editing begins.
NSTextDelegate documentation: here.
I'm not sure what you mena when you say "store the contents of the box into a variable (array, etc.) Are you hoping for an array of custom notes? Text views store a string of data, so the easiest way of storing its value is using one string; if you need an array of notes you'd have to split the string value into different paragraphs, which shouldn't be too hard.

A: DLL load fail error is because either you have not installed Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 or your CPU does not support AVX2 instructions
There is a workaround either you have to compile Tensorflow from source or use google colaboratory to work. Follow the instructions mentioned here to build Tensorflow from source.

Q: Cancel backButton click in my navigationController I have a custom navigationController :
#import "customNavigationController.h"
#import "StartViewController.h"
#import "EtapeViewController.h"
@implementation customNavigationController
- (UIViewController *)popViewControllerAnimated:(BOOL)animated
{
// Accueil du guide, on cache le navigationBar
if([self.viewControllers count] == 2){
self.navigationBarHidden = TRUE;
return [super popViewControllerAnimated:animated];
}
// Si on est pas à l'accueil, on fait l'action normal sur le backBarButton
else {
// Si on est dans une étape, le backButton va servir à reculer dans les étapes, et non reculer vers le workflow
NSString *className = NSStringFromClass([[self.viewControllers objectAtIndex:[self.viewControllers count] - 1] class]);
if ([className isEqualToString:@"EtapeViewController"]) {
EtapeViewController *etape = [self.viewControllers objectAtIndex:[self.viewControllers count] - 1];
if (etape.show_previous_button) {
[etape previousEtape:nil];
return FALSE;
}
return [super popViewControllerAnimated:animated];
}
else {
return [super popViewControllerAnimated:animated];
}
}
}
@end
In some case, I want to cancel the click event of the backButton (on the line that reads "return FALSE"), but it doesn't work.
Is there a way to do it?
A: in place of return FALSE, you can do:
return nil;
or
return [self topViewController];
Either should have the right side effect.
That being said, be careful with your UI design here. Make sure the user knowns why the back button doesn't work somehow.
A: I don't understand why you would make the Back button ignore taps? It seems like this would confuse users and the App Store team would consider this a bug. Perhaps you could you post a screenshot?
It would probably be better to redesign your interface and consider 1) using toolbar buttons for navigation (like Mobile Safari) or 2) fully support UINavigation based views rather than working around it.
Update: It sounds like you're going to perform a different action, like displaying a confirmation? I don't know of any official ways to do what you want, since the UINavigationControllerDelegate methods just notify you about transitions, they don't let you cancel/modify them. (And if the transition is animated then playing with the navigation controller's view stack probably won't help.)
So you could always float a transparent (or almost transparent) window over the back button and intercept taps that way. Here's some sample bar that does something similar with the status bar:
https://github.com/myell0w/MTStatusBarOverlay
A: Why don't you disable the back button in the situations that you don't want the user to tap it?

Q: using .wrapInner instead of .show() newbie here. I am trying to used jquery wrapInner to show the next choice for the user while trying to hide the original element. Here is my jsfiddle.
Once I click endorse radio button it hide the elements in between . The cancel button show the elements back. But clicking endorse radio button again nothing happen.
Any help on this would be more than appreciated !
html:
<div id="engr-action" >
<div id="engr-choice">
<input id="endorse" class="engr-choice" type="radio" name="encoder-pick"/>
<label for="endorse">ENDORSEMENT</label>
<input id="encode" class="engr-choice" type="radio" name="encoder-pick"/>
<label for="encode">ENCODE</label>
</div>
<button id="cancel-action">Cancel</button>
</div>
jquery:
$(function(){
$('#engr-choice').buttonset();
$('#cancel-action')
.button()
.click(function() {
$('#engr-choice').html('');
$('#endorse-edit').hide();
$('#engr-choice').wrapInner('<input id="endorse" class="engr-choice" type="radio" name="encoder-pick"/><label for="endorse">ENDORSEMENT</label>');
$('#engr-choice input').removeAttr('checked');
$('#engr-choice').buttonset('refresh');
return false;
});
$('#endorse').click(function(){
$('#engr-choice').html('');
$('#engr-choice').wrapInner('<div id="endorse-edit"><a href="">Edit</a></div>');
$('#endorse-edit').button();
return false;
});
});
A: Since your element is generated "on the fly", thru javascript, your $('#endorse').click(.. event wont work as that element did not exist on DOM, so in order to add events to your elements, created on the fly, you would need to use event delegation, so
change:
$('#endorse').click(function(){
..
to
$(document).on('click', '#endorse',function(){
...
See:: Updated jsFiddle
A: You can try this: Fiddle setup
$(function () {
$('#engr-choice').buttonset();
$('#cancel-action').button().click(function () {
$('#engr-choice').html('');
$('#endorse-edit').hide();
$('#engr-choice').append('<input id="endorse" class="engr-choice" type="radio" name="encoder-pick"/> <label for="endorse">ENDORSEMENT</label>');
$('#engr-choice input').prop('checked', false);
return false;
});
$('#engr-action').on('click', '#endorse', function () {
$('#engr-choice').html('');
$('#engr-choice').wrapInner('<div id="endorse-edit"><a href="">Edit</a></div>');
$('#endorse-edit').button();
});
});
As you are putting html elements via javascript/jQuery so direct binding of events won't be available for them, so you need to do it via event delegation that is to delegate the event to the static closest parent which is in your case is #engr-action or you can do it with $(document) which is always available to delegate the events.

Q: Read XML with attribute names in Scala I have the following XML:
<TABLES>
<TABLE attrname="Red">
<ROWDATA>
<ROW Type="solid" track="0" Unit="0"/>
</ROWDATA>
</TABLE>
<TABLE attrname="Blue">
<ROWDATA>
<ROW Type="light" track="0" Unit="0"/>
<ROW Type="solid" track="0" Unit="0"/>
<ROW Type="solid" track="0" Unit="0"/>

I am using Spark and Scala. I want to read each field in the ROW tag and differentiate by the attribute names. Currently the code below just reads all the values inside the ROW tag but I want to read them based on the attribute names.
val df = session.read
.option("rowTag", "ROW")
.xml(filePath)
df.show(10)
df.printSchema()
Thanks in advance.
A: Check below code.
val spark = SparkSession.builder().master("local").appName("xml").getOrCreate()

Q: CSS wordwrapping and overflow not breaking paragraph I have a paragraph next to a heading. Both are display:inline-block but when the page is compressed through a resolution reduction then the entire paragraph falls to the next line. I have tried wordwrapping and overflow but they seem to have no affect. Is there something else I can use ? Code below does not reflect the wordwrapping or overflow.
.header_class_name {
display: inline-block
}
.para_class_name {
display: inline-block
}
<h4 class="header_class_name">my title here</h4>
<p class="para_class_name">paragraph here</p>
A: You can use display: inline; inside of display: inline-block;.
.header_class_name {
display: inline;
}
.para_class_name {
display: inline;
word-break: break-word;
}
<h4 class="header_class_name">my title here</h4>
<p class="para_class_name">Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>
A: edit - adding a solution based on your comment
try using white-space: nowrap;, if that doesn't work, you can try setting the containing div size to a higher width.
you can try doing several things:
*
*wrap both divs with <nobr>
*make the parent div a flexbox with
flex-direction: row; flex-wrap: nowrap;
the problem with this solution is that they would 'leak' outside your viewport width, so I would consider allowing line break/making the font smaller/using elipsis
A: You can use min-width property, so when window shrinks, layout should stay firm.

Q: How to decode unicode string to unicode value I have a program in Python 2.7 that does the following:
*
*Ask the user for input (In Non English characters. E.g. Hebrew, English)
*Split each character of the sentence in a list. (The input can be a small paragraph, or an email)
*Convert the characters to Unicode values. So in the end every item of the list is a unicode escape char e.g. "u/0391" that can be manipulate it as string.
Ι started quite well but I can't split the letters in the array nor print the right unicode value.
Gr_text = unicode(raw_input("Type your message below:\n"), 'unicode-escape')
Gr = Gr_text.split()
print Gr
Example input:
Ενα απλο παραδειγμα.
The input (translate as "A simple example") is in Greek language without intonations. This sentence should be transform in a list as
['\u0395', '\u03bd', '\u03b1','\u0020', '\u03b1', '\u03c0', '\u03bb', '\u03bf','\u0020', '\u03c0', '\u03b1', '\u03c1', '\u03b1', '\u03b4', '\u03b5', '\u03b9', '\u03b3', '\u03bc', '\u03b1','\u0020',]
To point out I also want to convert spaces and special characters.
Then I get every letter of the list as string of unicode and not as simple letter so I can manipulate and give it other value.
A: I have tested this and it works for me but your mileage may vary.
import sys, locale
Gr_text = raw_input('Type your message below:\n').decode(sys.stdin.encoding or locale.getpreferredencoding(True))
Gr = Gr_text.split()
print Gr

Q: Random number generator that doesn't use rand()/srand() C functions I'm developing some library in C that can be used by various user applications.
The library should be completely "transparent" - a user application can init it and finalize,
and it's not supposed to see any change in the running application.
The problem is - I'm using C srand()/rand() functions in the library initialization,
which means that the library does affect user's application - if a user generates random numbers, they will be affected by the fact that rand() was already called.
So, can anyone point to some simple non-GPL alternative to rand() random number generator in C?
It doesn't have to be really strong - I'n not doing any crypto with the numbers.
I was thinking to write some small and really simple generator (something like take time and XOR with something and do something with some prime number and bla bla bla), but I was wondering if someone has a pointer to a more decent generator.
A: It generates the next number by keeping some state and modifying the state every time you call the function. Such a function is called a pseudorandom number generator. An old method of creating a PRNG is the linear congruential generator, which is easy enough:
static int rand_state;
int rand(void)
{
rand_state = (rand_state * 1103515245 + 12345) & 0x7fffffff;
return rand_state;
}
As you can see, this method allows you to predict the next number in the series if you know the previous number. There are more sophisticated methods.
Various types of pseudorandom number generators have been designed for specific purposes. There are secure PRNGs which are slow but hard to predict even if you know how they work, and there are big PRNGs like Mersenne Twister which have nice distribution properties and are therefore useful for writing Monte Carlo simulations.
As a rule of thumb, a linear congruential generator is good enough for writing a game (how much damage does the monster deal) but not good enough for writing a simulation. There is a colorful history of researchers who have chosen poor PRNGs for their programs; the results of their simulations are suspect as a result.
A: If C++ is also acceptable for you, have a look at Boost.
http://www.boost.org/doc/libs/1_51_0/doc/html/boost_random/reference.html
It does not only offer one generator, but several dozen, and gives an overview of speed, memory requirement and randomness quality.

Q: How can I have the same height for the color bar? I would like to plot some data, however the color bar is higher than the plot. How can I fix this?
import numpy as np
import matplotlib.pyplot as plt
import scipy.interpolate
fig, ax = plt.subplots()
# Generate data:
x = np.linspace(1, 1, 10)
y = np.linspace(1,100, 10)
for i in range(10, 100, 10):
x = append(x, np.linspace(i, i, 10))
y = append(y, np.linspace(1, 100, 10))
z = numpy.random.uniform(-5, 5, size=100)
# Set up a regular grid of interpolation points
xi, yi = np.linspace(x.min(), x.max(), 100), np.linspace(y.min(), y.max(), 100)
xi, yi = np.meshgrid(xi, yi)
# Interpolate
rbf = scipy.interpolate.Rbf(x, y, z, function='linear')
zi = rbf(xi, yi)
s = ax.imshow(zi, vmin=z.min(), vmax=z.max(), origin='lower',
extent=[x.min(), x.max(), y.min(), y.max()])
plt.xlim([0,200])
#s = ax.scatter(x, y, c=z, marker = 's')
plt.colorbar(mappable=s, ax=ax)
plt.show()
A: The easiest solution (for your example) is to remove the line
plt.xlim([0,200])
But since you've put it there, I assume that you really want/need it there. So then, you have to manually adapt the height of the colorbar:
cb = plt.colorbar(mappable=s, ax=ax)
plt.draw()
posax = ax.get_position()
poscb = cb.ax.get_position()
cb.ax.set_position([poscb.x0, posax.y0, poscb.width, posax.height])
Using the shrink argument of colorbar as @MaxNoe suggests might also do the trick. But you will have to fiddle around to get the right value.

Q: File_get_contents not evaluating to false when file does not exist I'm trying to test an exception in my code.
public function testGetFileThrowsException(){
$this->expectException(FileNotFoundException::class);
$file = "db.json";
$this->review->getData($file);
}
The "db.json" file doesn't exist. My goal is tp have the getData() file to throw the FileNotFoundException. Here is the getData() code:
public function getData($path){
if(file_get_contents($path) === false){
throw new FileNotFoundException;
}
return $file;
}
The problem is that instead of evaluating to False and throw the exception, the file_get_contents function returns:
1) CompanyReviewTest::testGetFileThrowsException
file_get_contents(db.json): failed to open stream: No such file or directory
So the test doesn't run successfully. Any ideas on why does this happen?
A: file_get_contents() generates an E_WARNING level error (failed to open stream) which is what you'll want to suppress as you're already handling it with your exception class.
You can suppress this warning by adding PHP's error control operator @ in front of file_get_contents(), example:
<?php
$path = 'test.php';
if (@file_get_contents($path) === false) {
echo 'false';
die();
}
echo 'true';
?>
The above echoes false, without the @ operator it returns both the E_WARNING and the echoed false. It may be the case that the warning error is interfering with your throw function, but without seeing the code for that it's hard to say.
A: You have 2 solution the poor one is to hide the error like that
public function getData($path){
if(@file_get_contents($path) === false){
throw new FileNotFoundException;
}
return $file;
}
Or check maybe if the file exist (better solution i guess)
public function getData($path){
if(file_exists($path) === false){
throw new FileNotFoundException;
}
return $file;
}

Q: Apply Function on DataFrame Index What is the best way to apply a function over the index of a Pandas DataFrame?
Currently I am using this verbose approach:
pd.DataFrame({"Month": df.reset_index().Date.apply(foo)})
where Date is the name of the index and foo is the name of the function that I am applying.
A: A lot of answers are returning the Index as an array, which loses information about the index name etc (though you could do pd.Series(index.map(myfunc), name=index.name)). It also won't work for a MultiIndex.
The way that I worked with this is to use "rename":
mix = pd.MultiIndex.from_tuples([[1, 'hi'], [2, 'there'], [3, 'dude']], names=['num', 'name'])
data = np.random.randn(3)
df = pd.Series(data, index=mix)
print(df)
num name
1 hi 1.249914
2 there -0.414358
3 dude 0.987852
dtype: float64
# Define a few dictionaries to denote the mapping
rename_dict = {i: i*100 for i in df.index.get_level_values('num')}
rename_dict.update({i: i+'_yeah!' for i in df.index.get_level_values('name')})
df = df.rename(index=rename_dict)
print(df)
num name
100 hi_yeah! 1.249914
200 there_yeah! -0.414358
300 dude_yeah! 0.987852
dtype: float64
The only trick with this is that your index needs to have unique labels b/w different multiindex levels, but maybe someone more clever than me knows how to get around that. For my purposes this works 95% of the time.
A: You can convert an index using its to_series() method, and then either apply or map, according to your needs.
ret = df.index.map(foo) # Returns pd.Index
ret = df.index.to_series().map(foo) # Returns pd.Series
ret = df.index.to_series().apply(foo) # Returns pd.Series
All of the above can be assigned directly to a new or existing column of df:
df["column"] = ret
Just for completeness: pd.Index.map, pd.Series.map and pd.Series.apply all operate element-wise. I often use map to apply lookups represented by dicts or pd.Series. apply is more generic because you can pass any function along with additional args or kwargs. The differences between apply and map are further discussed in this SO thread. I don't know why pd.Index.apply was omitted.
A: As already suggested by HYRY in the comments, Series.map is the way to go here. Just set the index to the resulting series.
Simple example:
df = pd.DataFrame({'d': [1, 2, 3]}, index=['FOO', 'BAR', 'BAZ'])
df
d
FOO 1
BAR 2
BAZ 3
df.index = df.index.map(str.lower)
df
d
foo 1
bar 2
baz 3
Index != Series
As pointed out by @OP. the df.index.map(str.lower) call returns a numpy array.
This is because dataframe indices are based on numpy arrays, not Series.
The only way of making the index into a Series is to create a Series from it.
pd.Series(df.index.map(str.lower))
Caveat
The Index class now subclasses the StringAccessorMixin, which means that you can do the above operation as follows
df.index.str.lower()
This still produces an Index object, not a Series.
A: Assuming that you want to make a column in you're current DataFrame by applying your function "foo" to the index. You could write...
df['Month'] = df.index.map(foo)
To generate the series alone you could instead do ...
pd.Series({x: foo(x) for x in foo.index})

A: you have to options:
*
*declare PatientClinicalTabComponent in PatientModule(and nowhere else). Just use it inside PatientModule
*create e new module called PatientClinicalTabModule. Declare PatientClinicalTabComponent inside PatientClinicalTabModule and then import PatientClinicalTabModule inside PatientModule
this will solve your problem

Q: What's the difference between overflow: auto and overflow: clip? Simple question, one element has overflow:auto and another element has overflow:clip.
What is the difference?
.some-div{
overflow: auto;
}
.another-div{
overflow: clip;
}
A: From the specification
If the computed value of overflow on a block box is neither visible nor clip nor a combination thereof, it establishes an independent formatting context for its contents.
The creation of formatting context is the main difference
Here is a demo
.box {
border:2px solid;
margin:10px;
}
.box div {
float:left;
width:50px;
height:50px;
background:blue;
}
<div class="box" style="overflow:auto">
<div></div> text
</div>
<div class="box" style="overflow:clip">
<div></div> text
</div>
Notice how in the second case, the div remain collapsed because there is no creating of a block formatting context to contain the float element

Q: nHibernate statistics per session I know I can get global statistics for nHibernate using these techniques
http://nhibernate.info/blog/2008/10/26/exploring-nhibernate-statistics-part-1-simple-data-fetching.html
What I'm after is a way to get statistics for the current session in the current thread.
EG, I want to know how many entities where loaded in my session, how many db queries made, etc.
I see Hibernating Rhinos can break down stats per session, so NH must be storing it in some form?
dave
A: Instead of using ISessionFactory.Statistics, just use ISession.Statistics.
class Program
{
static void Main(string[] args)
{
ISession session = NHibernateHelper.GetSession();
var stats = session.Statistics;
Console.WriteLine("Entity count: {0}", stats.EntityCount);
Console.WriteLine("Collection count: {0}", stats.CollectionCount);
Console.ReadLine();
}
}
Statistics at the session level are limited when compared with the session factory level though.

Q: Regex to remove whitespace in between quotes but not between words inside the quotes? I am programming in Java.
I am struggling to transform this:
Text0 Text1 " Text2 Text3 Text4 " Text5 Text6
into this:
Text0 Text1 "Text2 Text3 Text4" Text5 Text6
I have tried lookaheads and lookbehinds:
(?<=\")\s+(\w*\s*\w*)\s+(?=\")
manages to match all the text inside the quotes, but when switching to:
(?<=\")\s+(\W*\S*\W*)\s+(?=\")
I get an error. Not sure why.
My short knowledge of regex limits me. Help would be appreciated.
A: It's easier not to use (just) regex.
Split the string on quotes (-1 to keep any trailing empty parts):
String[] parts = str.split("\"", -1);
Trim the odd-numbered elements:
for (int i = 1; i < parts.length; i += 2) {
parts[i] = parts[i].trim();
}
Join the parts again:
String newStr = String.join("\"", parts);

Q: monaco editor theme can not be changed dynamically I want to update monaco editor theme on the fly, but I found it does not work:
this.editorOptions = {
...this.editorOptions,
readOnly: true, // this.readOnly,
value: this.code,
language: 'java',
theme: 'vs'
};
this.currentEditor.updateOptions(this.editorOptions);
If I change the readOnly, it worked fine, but theme is NOT updated at all.
the create logic is like this:
this.editorOptions = {
...this.editorOptions,
readOnly: this.readOnly,
value: this.code,
language: this.updatedType.toLowerCase(),
//theme: 'vs-dark'
theme: t === 'light' ? 'dv-light-theme' : 'dv-dark-theme'
};
this.currentEditor = monaco.editor.create(this._editorContainer.nativeElement, this.editorOptions);
Please help and show how you can update the theme on the fly dynamically.
A: I just learned from https://blog.expo.dev/building-a-code-editor-with-monaco-f84b3a06deaf that to set the theme you call monaco.editor.setTheme('<theme-name>'). I was incorrectly calling setTheme on my editor instance.

Q: Connecting to W3Schools sample WebService via jQuery I am trying to connect W3Schools sample webservice via jQuery Ajax but it's not working for me.
Here is the JS:
function ConnectToWebService() {
var pdata = "Celsius:123";
$.ajax({
type: "POST",
dataType: "text",
data:pdata,
contentType: "application/text; charset=utf-8",
url: "http://www.w3schools.com/webservices/tempconvert.asmx?op=CelsiusToFahrenheit",
success: function (msg) {
$('#divToBeWorkedOn').html(msg.d);
},
error: function (e) {
alert("could not connect to service");
}
});
}
A: The error on the page says $.mobile is undefined. Include the proper URL to where $.mobile is defined and try again.
A: This line doesn't work:
$.mobile.allowCrossDomainPages = false;
If you take it off your javascript will work. Just so you know, I'm getting here that "could not connect to service".
Next time insert some logs or alerts in your code to debug. I just put one before and one after the line that was not working to see if the ajax request was being sent and saw that this line was the problem.
(In chrome ctrl+shift+c opens debug window, open console and you can see js logs (console.log). A lot better than alert for debug)
Ps: For cross domain ajax call use jsonp, as Ehsan Sajjad commented:
*
*jQuery AJAX cross domain
*Make cross-domain ajax JSONP request with jQuery
Ps2: I never used this, but it might be useful: Cross-origin Ajax

Q: .NET desktop app to run on all screen size I have to develop an .NET app using C# that runs on all screen size(8", 10, 14, 22, etc). So whatever is the screen size, the app should work & dispaly properly.
How should I start up with this ? With this in mind I believe using WPF would be the best rather than WinForms (Pls correct if I am wrong). I can give weight to each component & text size and handle that but what about the actual window size. That height & width I can't define a number (like 300*250) or so. Window size shoula also be based on the screen size.
Can anyone help me know how do I work out with this. WPF or WinFroms ?
A: Use relative size/location instead of absolute (example -> Use Grid.RowDefinition = */Auto, instead of fixed size, Use stackpanel, use dock panel)
Automatic layout overview
Resolution independent or monitor size independent WPF apps
Same question on MSDN with links in answer
Metro Apps are supposed to run on different form factors. You can look at Guidelines for the different form factors on metro UI. It will help in understanding the challenges, and how to plan/resolve these challenges.

Q: Is PhantomJS one process per browser instance just like Chrome or is it single process? Google Chrome works in a single process per browser instance mode. This is a problem if the number of browser instances goes up to a very large number. I wish to do a lot of testing with PhantomJS with many browser instances and am worried about this issue.
A: PhantomJS is single process, just like node.js, and will never spawn something to process requests. Basically, everything is shared in the same instance (web pages, html ressources, ...)
You can spawn custom process, using execFile/spawn modules.

Q: Android Material Design on KitKat 4.4 I am starting to learn Android development. I read on the Google dev site that Material Design is only available on Android 5.0. I wonder why some applications on Android 4.4 have material design. I am using Android 4.4. Any guides or tips give me? Thanks.
A: There is a design backward compatibility library that bring important material design components to Android 2.1 and above.
See :
http://android-developers.blogspot.fr/2015/05/android-design-support-library.html
Generally speaking, Android always provides some support libraries to provide backward compatibility to previous version on Android.
You will find all you need here :
https://developer.android.com/topic/libraries/support-library/features.html
A: First I should remember Material Design isn't only some code or component else ,It's totally a concept about how design your app to get best UI/UX.
And yes ,android 5 and above ,have some pretty and new features and components ,that you can use some of them in android <5 by some support library that Google or someone else provide them ,
for example look at these two lib:
com.android.support:appcompat-v7
com.android.support:design
these are most useful libs by Google to have material components in android <5 development.

Q: How to compare two URLs in java? Here's a simple problem - given two urls, is there some built-in method, or an Apache library that decides whether they are (logically) equal?
For example, these two urls are equal:
http://stackoverflow.com
http://stackoverflow.com/
A: URL::equals reference
URL urlOne = new URL("http://stackoverflow.com");
URL urlTwo = new URL("http://stackoverflow.com/");
if( urlOne.equals(urlTwo) )
{
// ....
}
Note from docs -
Two URL objects are equal if they have the same protocol, reference equivalent hosts, have the same port number on the host, and the same file and fragment of the file.
Two hosts are considered equivalent if both host names can be resolved into the same IP addresses; else if either host name can't be resolved, the host names must be equal without regard to case; or both host names equal to null.
Since hosts comparison requires name resolution, this operation is a blocking operation.
Note: The defined behavior for equals is known to be inconsistent with virtual hosting in HTTP.
So, instead you should prefer URI::equals reference as @Joachim suggested.
A: While URI.equals() (as well as the problematic URL.equals()) does not return true for these specific examples, I think it's the only case where equivalence can be assumed (because there is no empty path in the HTTP protocol).
The URIs http://stackoverflow.com/foo and http://stackoverflow.com/foo/ can not be assumed to be equivalent.
Maybe you can use URI.equals() wrapped in a utility method that handles this specific case explicitly.
A: The following may work for you - it validates that 2 urls are equal, allows the parameters to be supplied in different orders, and allows a variety of options to be configured, that being:
*
*Is the host case sensitive
*Is the path case sensitive
*Are query string parameters case sensitive
*Are query string values case sensitive
*Is the scheme case sensitive
You can test it like so:
class Main {
public static void main(String[] args)
{
UrlComparer urlComparer = new UrlComparer();
expectResult(false, "key a case different", urlComparer.urlsMatch("//test.com?A=a&B=b", "//test.com?a=a&b=b"));

A: sameFile
public boolean sameFile(URL other)Compares two URLs,
excluding the fragment component.
Returns true if this URL and the other argument are equal without taking the fragment component into consideration.
Parameters:
other - the URL to compare against.
Returns:
true if they reference the same remote object; false otherwise.
also please go through this link
http://download.oracle.com/javase/6/docs/api/java/net/URL.html#sameFile(java.net.URL)
As iam unable to add comment , browser throwing Javascript error. so iam adding my comment here. regret for inconvience.
//this what i suggeted
>URL url1 = new URL("http://stackoverflow.com/foo");
>URL url2 = new URL("http://stackoverflow.com/foo/");
>System.out.println(url1.sameFile(url2));
// this is suggested by Joachim Sauer
>URI uri = new URI("http://stackoverflow.com/foo/");
>System.out.println(uri.equals("http://stackoverflow.com/foo"));
// Both are giving same result
so Joachim Sauer check once.

Q: Is that correct work of recycleView android 7.0+? I have list of data, and size of data = 7, but when I try to display all the elements, it displays only 6 and in the debug mode in the method onBindViewHolder the last binds position is 5. I thought that was some bugs with my list, so i added 8th element, but it all the same displays only 6 elements.
On android lower than 7.0 everything works properly
Adapter
public class BottomNavigationAdapter extends RecyclerView.Adapter<BottomNavigationAdapter.MyViewHolder> {
private ArrayList<BottomNavigationData> bottomNavigationDatas = new ArrayList<>();
private Context mContext;
public BottomNavigationAdapter(ArrayList<BottomNavigationData> bnl, Context context) {
bottomNavigationDatas = bnl;
mContext = context;
}
public class MyViewHolder extends RecyclerView.ViewHolder {
ImageView imageView;
TextView txtview;
public MyViewHolder(View view) {
super(view);
imageView = (ImageView) view.findViewById(R.id.ivBottomItemIcon);
txtview = (TextView) view.findViewById(R.id.tvBottomTitle);
}
}
@Override
public BottomNavigationAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.bottom_navigation_item, parent, false);
return new MyViewHolder(itemView);
}
@Override
public void onBindViewHolder(BottomNavigationAdapter.MyViewHolder holder, int position) {
BottomNavigationData currentNavigationData = bottomNavigationDatas.get(position);
String image_url = Constants.SERVER_HOST + "/" + currentNavigationData.image;
Glide.with(mContext).load(image_url).into(holder.imageView);
holder.txtview.setText(currentNavigationData.name);
holder.imageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
}
});
}
@Override
public int getItemCount() {
return (bottomNavigationDatas != null) ? bottomNavigationDatas.size() : 0;
}
recycle view initialisation
rvBottomNavigation = (RecyclerView) view.findViewById(R.id.rvBottomNavigation);
LinearLayoutManager horizontalLayoutManager = new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false);
rvBottomNavigation.setLayoutManager(horizontalLayoutManager);
bottomNavigationAdapter = new BottomNavigationAdapter(bottomNavigationDatas, getActivity().getApplicationContext());
rvBottomNavigation.setAdapter(bottomNavigationAdapter);
bottomNavigationAdapter.notifyDataSetChanged();
my output on android 7.0+:
output on lower than 7.0:
So as you can see, i have one more item at the end.
Code is exactly the same. How can i fix it?

A: Code seems fine but I am sure this is not the way to do it,
*
*You should null check your arrayList in your activity itself, then proceed to set adapter.
*For adapter,you should provide activityContext rather than applicationContext, adapters often hold listeners to open activities or to show toasts, it that case it should be activityContext not applicationContext
*For your problem, I will suggest setting layout manager after setting adapter. In this way, you won't need to call notifyDatasetChang.
Updated part
In your xml, you are adding RecyclerView inside horizontal scrollview which is the reason its giving trouble. Take your recyclerview outside the horizontal scrollview because you are setting the LinearLayoutManager with horizontal orientation in your code anyways. Then set both height and width of the recyclerview to match_parent. Also, if you don't want to add anything else in the footer view, you can remove the linearLayout and set your recyclerview as footer with width=match_parent and height=60dp.
Don't forget to delete horizontalscrollview code.

Q: Disposal of Shared members in a ServicedComponent with ActivationOption.Server For several reasons I need to create a COM+ component in .Net Framework 4. The intent is to host the component in its own process (dllhost.exe), hence the usage of ActivationOption.Server.
My component code needs to persist data between object activations, which is maintained by a worker thread. This worker thread and its data are held in static (shared) members of my base class. The shared data is independent of the caller, its security context, transactions, etc. Also, the worker thread performs background processing on the data.
I need to clean up the data and orderly terminate the worker thread when the dllhost process is disposed. Since there are no static (shared) destructors, I don't know how to do it. Is there anything I could implement while inheriting ServicedComponent? Any other ideas? Thank you.
Here's some code to start:
Imports System.EnterpriseServices
<Assembly: ApplicationName("MySender")>
<Assembly: ApplicationActivation(ActivationOption.Server)>
<ClassInterface(ClassInterfaceType.None), ProgId("MySender.Sender")> _
<Transaction(EnterpriseServices.TransactionOption.NotSupported)> _
Public Class Sender
Inherits ServicedComponent
Implements SomeLib.IMsgSender
Shared worker As myWorker
Shared sync As New Object
Public Sub MyInstanceMethod(msg as string) Implements SomeLib.IMsgSender.SendMessage
SyncLock sync
If worker Is Nothing Then
worker = New myWorker
worker.StartThread()
End If
End SyncLock
worker.Process(msg)
End Sub
'Something like this does not exist!'
Shared Sub Dispose()
SyncLock sync
If worker IsNot Nothing Then
worker.StopThread()
End If
End SyncLock
End Sub
End Class
A: The AppDomain.ProcessExit event will fire before unloading the domain. If the code to run doesn't take too long, it could be used like this:
Imports System.EnterpriseServices
<Assembly: ApplicationName("MySender")>
<Assembly: ApplicationActivation(ActivationOption.Server)>
<ClassInterface(ClassInterfaceType.None), ProgId("MySender.Sender")> _
<Transaction(EnterpriseServices.TransactionOption.NotSupported)> _
Public Class Sender
Shared Sub New
AddHandler AppDomain.CurrentDomain.ProcessExit, AddressOf MyDisposalCode
End Sub
'....
Shared Sub MyDisposalCode(sender as Object, e as EventArgs)
'My disposal code
End Sub
End Class
It's important to notice that .Net will enforce a 2 second timeout on this code.

Q: String Is Empty When Read So basically I call a MYSQL query that grabs a secret key that was generated and saved to the database. Then it sets a string called "ServerCryptKey" to the output of the query which should be "yQnK9xDCxaLIGwzpsKEXeJR2Iz5ZoHnWyLHHikkQv5zbC8B5Sf36ZU9HteHSW5Ov".
$SQLGetUsers = $odb -> query("SELECT * FROM settings");
while ($getInfo = $SQLGetUsers -> fetch(PDO::FETCH_ASSOC))
{
$NewServerHash = $getInfo['newhash'];
}
I can call the string fine and it will read the above ^, but whenever I have it call it from this function it reads nothing and shows it's an empty string...
function encrypt($data)
{
$secret = $ServerCryptKey;
//Generate a key from a hash
$key = md5(utf8_encode($secret), true);
//Take first 8 bytes of $key and append them to the end of $key.
$key .= substr($key, 0, 8);
//Pad for PKCS7
$blockSize = mcrypt_get_block_size('tripledes', 'ecb');
$len = strlen($data);
$pad = $blockSize - ($len % $blockSize);
$data .= str_repeat(chr($pad), $pad);
//Encrypt data
$encData = mcrypt_encrypt('tripledes', $key, $data, 'ecb');
return base64_encode($encData);
}
function decrypt($data)
{
$secret = $ServerCryptKey;
//Generate a key from a hash
$key = md5(utf8_encode($secret), true);
//Take first 8 bytes of $key and append them to the end of $key.
$key .= substr($key, 0, 8);
$data = base64_decode($data);
$data = mcrypt_decrypt('tripledes', $key, $data, 'ecb');
$block = mcrypt_get_block_size('tripledes', 'ecb');
$len = strlen($data);
$pad = ord($data[$len-1]);
return substr($data, 0, strlen($data) - $pad);
}
If anyone can help me figure out why this doesn't grab the string, please let me know, thanks!

Q: Angular bootstrap button click function I am using a simple form of my template. In form there is already a validation is added i just need to check when user click on button after all required field how is it possible ?
<section class="contact-area pb-80" style="margin-top:10%">
<div class="container">
<div class="section-title">
<h2>Your Information</h2>
<div class="bar"></div>
<p>Please provide the correct information we will contact you with your information.</p>
</div>
<div class="row h-100 justify-content-center align-items-center">
<div class="col-lg-6 col-md-12">
<img src="assets/img/1.png" alt="image">
</div>
<div class="col-lg-6 col-md-12">
<form id="contactForm">
<div class="row">
<div class="col-lg-12 col-md-12">
<div class="form-group">
<input type="text" name="name" id="name" class="form-control" required placeholder="Enter your name">
</div>
</div>
<div class="col-lg-12 col-md-12">
<div class="form-group">

</div>
<div class="col-lg-12 col-md-6">
<div class="form-group">
<input type="text" name="phone_number" id="phone_number" required class="form-control" placeholder="Enter your number (Whats app)">
</div>
</div>
<div class="col-lg-12 col-md-6">
<div class="form-group">
<input type="text" name="msg_subject" id="msg_subject" class="form-control" required placeholder="Enter your skype name">
</div>
</div>
<div class="col-lg-12 col-md-12">
<button type="submit" class="btn btn-primary">Send Message</button>
</div>
</div>
</form>
</div>
</div>
</div>
</section>
This is my code I need to simply check when user clicks on Send Message But after all fields are filled as in form. Validation is working fine but the problem is how can I check the button?
I have created a simple function like this
submit(){
console.log('submit');
}
I if add (click)="submit()" on the button so every time the user clicks it's calling the function. I want when all fields are filled then this function can work.
A: Inner template:
<form #myForm="ngForm">
<input ngModel name="name" type="text" required />
<input ngModel name="email" type="email" required />
<input ngModel name="phone-number" type="text" required />
<button (click)="onSubmit(myForm)">Submit</button>
</form>
Innner .ts:
onSubmit(form: NgForm) {
console.log(form.invalid);
}
Be sure that you have imported FormsModule into your module:
import { FormsModule } from '@angular/forms';
@NgModule({
// ...
imports: [..., FormsModule, ...],
// ...
})
A: Important: import { FormsModule } from '@angular/forms'; into your app-module and add it to the imports array.
@NgModule({
imports: [FormsModule],
})
Create a template variable in form element like myForm given below and on button tag make use of property binding [disabled]="!myForm.form.valid". Now Submit button will only work when each form element is filled.
Template file:
<form #myForm="ngForm" method="POST" (ngSubmit)="submitForm(myForm)">
<div>
<label>Name</label>
<input name="name" type="text" required ngModel/>
</div>
<div>
<label>Email</label>
<input name="email" type="email" required ngModel/>
</div>
<div>
<label>Phone no</label>
<input name="phone" type="number" required ngModel/>
</div>
<button type="submit" [disabled]="!myForm.form.valid">Submit</button>
<pre>{{myForm.value | json}}</pre>
</form>

Q: What is the most efficient way I can to get a list of locations sorted by proximity given a location? For example,
Say I have a database of locations (latitude/longtitude), and a point. How can I grab the top 25 nearest locations from the database of locations?
Is there too a library, or a resource I can read up on various geospatial operations like above? Thanks!
A: What you want to do sounds like a nearest neighbour search.
K-d trees are an efficient data structure to achieve this.
The CGAL library has spatial searching functions if you're looking for a library for C++.

Q: Grouping data using a value from a deep subarray How can I assign first level keys using a column value from the third level of a multidimensional array?
My input:
$array = [
[
["ID" => 2, "vendor_id" => "37", "order_id" => 776],
],
[
["ID" => 2, "vendor_id" => "37", "order_id" => 786],
]
];
My current output is like this:
array(1) {
[787]=>
array(2) {
[0]=>
array(40) {
["ID"]=>
string(1) "1"
["vendor_id"]=>
string(2) "37"
["order_id"]=>
string(3) "776"
}
[1]=>
array(40) {
["ID"]=>
string(1) "2"
["vendor_id"]=>
string(2) "37"
["order_id"]=>
string(3) "787"
}
}
}
I want to group the value of order_id separately as a key - the end result would look like this:
array(1) {
[776]=>
array(2) {
[0]=>
array(40) {
["ID"]=>
string(1) "2"
["vendor_id"]=>
string(2) "37"
["order_id"]=>
string(3) "776"
}
}
[787]=>
array(2) {
[0]=>
array(40) {
["ID"]=>
string(1) "2"
["vendor_id"]=>
string(2) "37"
["order_id"]=>
string(3) "787"
}
}
}
A: Get the current item or use reset and extract the entire columns indexing by order_id:
$result = array_column(current($array), null, 'order_id');
If there could be multiple arrays, then just loop and append:
$result = [];
foreach($array as $v) {
$result += array_column($v, null, 'order_id');
}
A: you can use that function
//$array is your input array
//$mergedArray is the result wanted
$mergedArray = array_reduce($array, function($acc, $val) {
foreach ($val as $order) {
$acc[$order['order_id']] = $order;
}
return $acc;
}, []);
you can try it on http://sandbox.onlinephpfunctions.com/
<?php
$array = [
787 => [
0 => [ "ID" => 1, "vendor_id" => "37", "order_id" => 776],
1 => [ "ID" => 2, "vendor_id" => "37", "order_id" => 787],
2 => [ "ID" => 1, "vendor_id" => "37", "order_id" => 790],
],
734 => [
0 => [ "ID" => 1, "vendor_id" => "37", "order_id" => 722],
1 => [ "ID" => 2, "vendor_id" => "37", "order_id" => 735],
2 => [ "ID" => 1, "vendor_id" => "37", "order_id" => 734],
],
];
$t = array_reduce($array, function($acc, $val) {
foreach ($val as $order) {
$acc[$order['order_id']] = $order;
}
return $acc;
}, []);
var_dump($t);
A: The other answers do not maintain the multi-level structure described as your desired output. The order_id values must be used as first level keys, and the second level keys must be incremented/indexed as they are encountered. This will allow for multiple entries which share the same first level key.
foreach() inside of a foreach(): (Demo)
$result = [];
foreach ($array as $group) {
foreach ($group as $row) {
$result[$row['order_id']][] = $row;
}
}
var_export($result);
array_reduce() with foreach(): (Demo)
var_export(
array_reduce(
$array,
function ($carry, $group) {
foreach ($group as $row) {
$carry[$row['order_id']][] = $row;
}
return $carry;
}
)
);

Q: Sharepoint - Load a form's view based on user I am using a data connection list to load desired views in an InfoPath form on SharePoint. I have a permission list with 2 columns: usernames and control group. My form on the main list loads a specific view based on what the username and group are of the permission list. You have to filter out the group based on the form's username() function to match the username column and set that as a condition to (on form load) change it to a specific view.
All this works, but the problem comes in when you have a user with multiple control groups. The filter only returns the first instance it finds. I can't think of a way to fix this. Maybe load the other list as a repeating table into the form, but then how would I reference that table in the conditions of a form load rule? Or is there a way to get a field filter to look past the first item it finds?
Update: I forgot to mention that I have to use a field to hold your filtered username:id:group aka group[title=username()] and then use that in the form load conditions. I think this is where the problem is, as this filter is what doesn't store all instances of the users id from the control list, but only the first.
SharePoint 2010 with forms created in InfoPath 2010
A: Are you querying the data in from info path or using visual studio, if you are querying in info path check the condition as Display name matches the username() and the query the data

Q: KeyEvent.KEYCODE_VOLUME_UP(DOWN) registering double hits I have a simple app where I do the following:
public void onClick(View v){
switch(v.getId()) {
case R.id.buttonup:
onButtonUp();
break;
case R.id.buttondown:
onButtonDown();
break;
}
}
public boolean dispatchKeyEvent(KeyEvent event){
int keyCode = event.getKeyCode();
switch (keyCode) {
case KeyEvent.KEYCODE_VOLUME_UP:
onButtonUp();
return true;
case KeyEvent.KEYCODE_VOLUME_DOWN:
onButtonDown();
return true;
default:
return super.dispatchKeyEvent(event);
}
}
void onButtonUp(){
increment_some_static_class_variable;
}
void onButtonUp(){
decrement_some_static_class_variable;
}
The thing is, whenever I press volume buttons, the onButtonUp and onButtondown functions are called twice. This does not happen when I press on screen buttons (handled in onClick(View)). I didn't find anybody having this issue so I am asking the folks here. I am new to Android and this is my first Application. Using Log, I found that both calls to onButtonUp and onButtonDown are coming from dispatchKeyEvent function. What could be wrong here? I hope I explained the problem well. Suggestions/Solutions are most welcome.
A: KeyEvent can represent multiple actions, specifically both ACTION_DOWN and ACTION_UP. Since you aren't checking the action in your dispatchKeyEvent callback you are calling your button click methods for both DOWN and UP events on the volume buttons. Try like this:
public boolean dispatchKeyEvent(KeyEvent event){
int keyCode = event.getKeyCode();
if(event.getAction() == KeyEvent.ACTION_DOWN){
switch (keyCode) {
case KeyEvent.KEYCODE_VOLUME_UP:
onButtonUp();
return true;
case KeyEvent.KEYCODE_VOLUME_DOWN:
onButtonDown();
return true;
default:
return super.dispatchKeyEvent(event);
}
}

Q: What are the next step after compiling PYBIND11_MODULE in C++ file I was trying to use PYbind 11 to wrap the following small C++ test programme into a Python module, so I can call the test C++ function from python files.
My problem is : while the C++ file compiled successfully, I have no clue as to what steps to take next to import the newly created module file in python.
I tried to run "from example import add" in a test Python file in Spyder but received error message saying there is no module named example.
I'm using Windows10 (x64bit), Python3.7 and Visual studio 2017 community.
Can some one please help? Thank you very much!

UPDATE: I followed Stuart's suggestion below when building my test c++ programme. I made two attempts: at the first attempt, I changed Target Extension to ".pyd"; whereas at the second attempt, I kept Target Extension as "dll".
In both attempts, I received the same error message from Visual Studio, which seem to suggest that the DLL file being built can not be started (as shown in the screenshot that immediately follows)
Error Messages for Starting DLL Programme
However, the actual building of dll file seemed successful, as I can see one dll file and one Python Extension Module file, with filenames and path listed as follows:
C:\Users\rmili\source\repos\ConsoleApplication5\x64\Debug\ConsoleApplication5.dll
and
C:\Users\rmili\source\repos\ConsoleApplication5\x64\Debug\ConsoleApplication5
The Visual Studio output message upon building is pasted at the end.
My problem is: I created a Test.py file in the same directory (C:\Users\rmili\source\repos\ConsoleApplication5\x64\Debug)
and tried to run it in Spyder after including just one line command "import example ". Sypder returned a error message saying " No MODULE Named Example".
Can anyone please help? Thanks a lot!

As shown in the following screenshot, example module can not be found in Windows command line prompt.
[Unable to find example module in Windowscommand line prompt]3
A: Make sure the compiled output file is named example.pyd (or has a symlink of that name pointing to it), and try running python from the same directory.
Update: How to build a .pyd in Visual Studio
On Windows, compiled Python modules are simply DLL files, but they have a .pyd file extension. You mentioned that your C++ file compiles successfully. Did you compile it as an executable (.exe), or as a .dll? You should compile it as a DLL, but change the file extension to .pyd.
The Visual Studio documentation explains how to change your project to create a DLL. Here's what it says:
*
*Open the project's Property Pages dialog box. For details, see Set C++ compiler and build properties in Visual Studio.
*Click the Configuration Properties folder.
*Click the General property page.
*Modify the Configuration Type property.
Also, on that same settings page, you can find an option to change the Target Extension property. Change it to .pyd. (Or simply rename the file yourself after it is built.)
Update 2
I think you need to change three settings:
*
*Target Name
*
*Change to example
*Target Extension
*
*Change to .pyd
*Configuration Type
*
*Change to Dynamic Library (.dll)
Also, I recommend deleting (or commenting out) everything from example.cpp except for the code shown below. (I don't know if the presence of a main() function may cause problems, so just remove it.)
After that, building your project should produce the following file:
C:\Users\rmili\source\repos\ConsoleApplication5\x64\Debug\example.pyd
Than, from the Spyder console, try this:
import os
d = "C:\\Users\\rmili\\source\\repos\\ConsoleApplication5\\x64\\Debug"
os.chdir(d)
import example
example.add(1,2)
I don't have a Windows machine to test with. But in case it's useful, here's how I compiled your example on my Mac. (On Mac and Linux, they use the extension .so instead of .pyd.)
// example.cpp
#include <pybind11/pybind11.h>
int add(int i, int j) {
return i + j;
}
PYBIND11_MODULE(example, m) {
m.doc() = "pybind11 example plugin";
m.def("add", &add, "A function which adds two numbers");
}
$ # Compile
$ clang++ -I${CONDA_PREFIX}/include -I${CONDA_PREFIX}/include/python3.7m -undefined dynamic_lookup -shared -o example.so example.cpp
$ # Test
$ python -c "import example; print(example.add(10,20))"

A: I have found answer to my problem:
*
*Make sure all steps I described previously in my post are done
*this is what I missed -` It is important to make sure the file type of "example" is Python Extension Module, as shown in the following screenshot .
As shown in screenshots of my Updates, initially the Type of my "example.pyd" file was just "File". I managed to convert it to Python Extension Module by adding "cp35-win_amd64." in the file extension, resulting in file name "examplelib.cp35-win_amd64.pyd", and then remove the same texts that were added.

Q: scaling up angular firestore app by associating data to each user I created an app using Angular 7, and crud with firestore. Everything is working fine with one user. Now, I am trying to scale it, and associate data with each logged user. I can't find detailed material on the web.
I have users in collection. I want to create a collection of 'vacations' and nest it under each user, for his collection of vacations. I believe the first step, is to get the current logged user uid, and update whatever function I might have, to edit the collection, then .doc('current user id').
This is code I used to get current user's uid:
this.userID = this.firestore.collection('users').doc(this.auth().user.uid);
errors in pre-compiler:
1- Type 'AngularFirestoreDocument<{}>' is not assignable to type
'string'
2- Cannot invoke an expression whose type lacks a call signature. Type
'AuthService' has no compatible call signatures.
This is currently how the data is structured:
This is the auth service:
export class AuthService {
user$: Observable<User>;
constructor(
public afAuth: AngularFireAuth,
public afs: AngularFirestore,
public router: Router
) {
// Get the auth state, then fetch the Firestore user document or return null
this.user$ = this.afAuth.authState.pipe(
switchMap(user => {
// Logged in
if (user) {
return this.afs.doc<User>(`users/${user.uid}`).valueChanges();
} else {
// Logged out
return of(null);
}
})
)
}
googleLogin() {
const provider = new auth.GoogleAuthProvider()
return this.oAuthLogin(provider);
}
public oAuthLogin(provider) {
return this.afAuth.auth.signInWithPopup(provider)
.then((credential) => {
this.updateUserData(credential.user)
})
}
public updateUserData(user) {
// Sets user data to firestore on login
const userRef: AngularFirestoreDocument<User> = this.afs.doc(`users/${user.uid}`);
const data = {
uid: user.uid,
email: user.email,
displayName: user.displayName,
photoURL: user.photoURL
}
return userRef.set(data, { merge: true })
}
}
Appreciate your help.
A: Googles official answer can be found here - Get the currently signed-in user - Firebase
Below is a function that returns a promise of type string. The promise resolves with the user's uid which is returned from onAuthStateChangedwhich() along with the rest of the user's firebase auth object(displayName...etc).
getCurrentUser(): Promise<string> {
var promise = new Promise<string>((resolve, reject) => {
this.afAuth.auth.onAuthStateChanged(returnedUser => {
if (returnedUser) {
resolve(returnedUser.uid);
} else {
reject(null);
}
});
})
return promise
}
You would call it in the constructor or ngOninit:
userDoc: User = null;
constructor() {
this.getCurrentUser().then((userID: string) => {
//here you can use the id to get the users firestore doc
this.afs.collection('users').doc(userID).valueChanges()
.subscribe(userFirestoreDoc => { // remember to subscribe
this.userDoc = userFirestoreDoc;
})
}).catch(nullID => {
//when there is not a current user
this.userDoc = null
})
}
To add a collection for 'vacations' nested in the users doc you need to add a sub collection to the that users firestore doc. I would advise only doing this once the user gets/adds their first vacation. You can simply set a doc in the subcollection and if the sub collection doesn't already exist firestore will first create it and then add the new doc(vaction) so this is the only code you need to set the new collection and new vaction inside that collectio.
this.afs.collection('users').doc(this.userDoc.uid).collection('vacations).add(vactionObject).then(returnedVaction => {
}).catch(error => {
})
A: users =》last login
This field on the google auth user object is updated on every new login with the time of the last success login

Q: Laravel 5 dynamically run migrations so I have created my own blog package in a structure of Packages/Sitemanager/Blog I have a service provider that looks like the following:
namespace Sitemanager\Blog;
use Illuminate\Support\ServiceProvider as LaravelServiceProvider;
class BlogServiceProvider extends LaravelServiceProvider {
/**
* Indicates if loading of the provider is deferred.
*
* @var bool
*/
protected $defer = false;
/**
* Bootstrap the application events.
*
* @return void
*/
public function boot() {
$this->handleConfigs();
$this->handleMigrations();
$this->handleViews();
$this->handleRoutes();
}
/**
* Register the service provider.
*
* @return void
*/
public function register() {
// Bind any implementations.
$this->app->make('Sitemanager\Blog\Controllers\BlogController');
}
/**
* Get the services provided by the provider.
*
* @return array
*/
public function provides() {
return [];
}
private function handleConfigs() {
$configPath = __DIR__ . '/config/blog.php';
$this->publishes([$configPath => config_path('blog.php')]);
$this->mergeConfigFrom($configPath, 'blog');
}
private function handleTranslations() {
$this->loadTranslationsFrom(__DIR__.'/lang', 'blog');
}
private function handleViews() {
$this->loadViewsFrom(__DIR__.'/views', 'blog');
$this->publishes([__DIR__.'/views' => base_path('resources/views/vendor/blog')]);
}
private function handleMigrations() {
$this->publishes([__DIR__ . '/migrations' => base_path('database/migrations')]);
}
private function handleRoutes() {
include __DIR__.'/routes.php';
}
}
Now, what i would like to do is run the migrations dynamically if they have never been run before or within an installation process i suppose. I've seen in older documentation you could so something like this:
Artisan::call('migrate', array('--path' => 'app/migrations'));
However, this is invalid in laravel 5, how can I approach this?
A: Artisan::call('migrate', array('--path' => 'app/migrations'));
will work in Laravel 5, but you'll likely need to make a couple tweaks.
First, you need a use Artisan; line at the top of your file (where use Illuminate\Support\ServiceProvider... is), because of Laravel 5's namespacing. (You can alternatively do \Artisan::call - the \ is important).
You likely also need to do this:
Artisan::call('migrate', array('--path' => 'app/migrations', '--force' => true));
The --force is necessary because Laravel will, by default, prompt you for a yes/no in production, as it's a potentially destructive command. Without --force, your code will just sit there spinning its wheels (Laravel's waiting for a response from the CLI, but you're not in the CLI).
I'd encourage you to do this stuff somewhere other than the boot method of a service provider. These can be heavy calls (relying on both filesystem and database calls you don't want to make on every pageview). Consider an explicit installation console command or route instead.
A: After publishing the package:
php artisan vendor:publish --provider="Packages\Namespace\ServiceProvider"
You can execute the migration using:
php artisan migrate
Laravel automatically keeps track of which migrations have been executed and runs new ones accordingly.
If you want to execute the migration from outside of the CLI, for example in a route, you can do so using the Artisan facade:
Artisan::call('migrate')
You can pass optional parameters such as force and path as an array to the second argument in Artisan::call.
Further reading:
*
*https://laravel.com/docs/5.1/artisan
*https://laravel.com/docs/5.2/migrations#running-migrations
A: For the Laravel 7(and probably 6):
use Illuminate\Support\Facades\Artisan;
Artisan::call('migrate');
will greatly work.

Q: logits and labels must be broadcastable, labels and logits dimension mismatch I am new to Tensorflow and making a Multiclass Classifier. My dataset has 6 classes with images 150x150.
I am getting error regarding Mismatch of dimensions of Logits and Labels,
I have seen other such questions on stackoverflow and my problem don't seem to be any of them.
Please anyone tell me what's the error, and also tell while constructing the I need not to tell batch size for output layer ( it's None if you see model.summary,it is automatically known later), so what things could affect it.?
The Error says:
logits and labels must be broadcastable: logits_size=[40,6] labels_size=[10,6]
Model is defined as follows:
batch_size = 10

A: It seems you are using AlexNet, but on samll size images
If you are using AlexNet architecture on smaller images, you need to resize images or you have to do some changes in Pool and Stride hyperparameters, because with current shape something funcky happens in conv5 affecting the architecture.

Q: Add dimension to pandas DataFrame I have a pandas DataFrame that includes a pipe-separated string in one of the fields. I've split this into a list inside an apply and added it to the DataFrame. The number and content of the values in the pipe-separated string vary.
df = DataFrame([{'wibble': 'a', 'pipestring': 'aa|aaa|aaa'},
{'wibble': 'b', 'pipestring': 'bb|bbbb|bbb|bbbbbb'}])
df['pipelist'] = df['pipestring'].map(lambda x: x.split('|'))
I'm pretty new to pandas so could be completely wrong about this, but I think this would be better represented via a DataFrame with multiple index levels so I can take advantage of panda's indexing and other (fabulous) tools. However I can't figure out how to do this. Any pointers / advice on what I should be doing instead much appreciated.
A: What is your computational goal more specifically?
Here's a way to split your data up and create a combined frame
In [44]: x = df['pipestring'].apply(lambda x: pd.Series(x.split('|')))
In [45]: x
Out[45]:
0 1 2 3
0 aa aaa aaa NaN
1 bb bbbb bbb bbbbbb
In [46]: df.join(x).set_index(['wibble'])
Out[46]:
pipestring pipelist 0 1 2 3
wibble
a aa|aaa|aaa [aa, aaa, aaa] aa aaa aaa NaN
b bb|bbbb|bbb|bbbbbb [bb, bbbb, bbb, bbbbbb] bb bbbb bbb bbbbbb
A: The quickest way to get started with that is to stack your dataframe:
In [44]: df = df.stack()
In [45]: df.ix[0, 'pipelist']
Out[45]: ['aa', 'aaa', 'aaa']
In [46]: df
Out[46]:
0 pipestring aa|aaa|aaa
wibble a
pipelist [aa, aaa, aaa]
1 pipestring bb|bbbb|bbb|bbbbbb
wibble b
pipelist [bb, bbbb, bbb, bbbbbb]
Does that get you where you want to be?

Q: MaxJsonLength error in NewtonSoft JsonConvert.SerializeObject I have a ASP.NET project, with some AJAX calling a webmethod, that would return JSON.
If the DataSet has about 100 lines, there is no problem. But with 1000 lines, it launch the error:
Error during serialization or deserialization using JSON JavaScriptSerializer. The size of the string exceeds the value set in the maxJsonLength property
[WebMethod(EnableSession = true)]

}
else
{
return "false";
}
}
}
How can I solve this by setting a configuration in the method?
I don't want to change the web.config
A: I had the similar issue and took a while to figure out the problem and fix.

Q: Multiple web docker containers on a host What is the best practice concerning multiple web containers running on a single host.
How would I assign these subdomains
subdomain1.mydomain.com to container1 and
subdomain2.mydomain.com to container2
when both containers run on host1 with ports 50000 and 50001?
How would this configuration work if I wanted to assign paths to both containers e.g.: mydomain.com/pathnameleadingtocontainer1 , mydomain.com/pathnameleadingtocontainer2 again with both containers running on host1 with ports 50000 and 50001?

Q: How to process the files in NodeJS sent from client FormData? I use HTML5 FormData to upload files from the client to Node Server. In the node server, I have included multiparty module to process the uploaded, but not sure of how it works.
server.js:
var parms = urlLib.parse(req.url, true);
var form = new multiparty.Form();
form.parse(req, function (err,fields,files) {
console.log(fields, files);
});
I want to know how to write the code for processing the uploaded file. I have tried using fs.readFile and fs.createReadStream, but node threw an error "file path must be of type String" but the uploaded files are blob object. So, how do i proceed further?

Q: socket.io client not able to connect and receive messages emit by server I am emitting messages from socket.io server running on port 8001
but my socket.io client not able to connect and receive these messages
my index.html (client):
<script src="https://cdn.socket.io/socket.io-4.0.0.js"></script>
<script>
//var socket = io();
//var socket = io.connect('http://localhost:8001');
var socket = io('http://localhost:8001', { transports : ['websocket'] });
socket.on('connect', function(){
console.log("connected");
socket.on("message", data => {
console.log(data);
});
});
</script>
My nodejs server code:
const app = require("express")();
const server = require("http").createServer(app);
const io = require("socket.io")(server, {
cors: {
origin: '*',
}
});
io.on("connection", () => {
console.log("Connected!");
});
var redis = require('redis');
//var url = "redis://:@localhost:6379";
//var redis = require('redis-url').connect();
//var client = redis.createClient(url);
var client = redis.createClient();
//var client = redis.createClient();

client.subscribe('notification');
client.on('message', function(channel, msg) {
console.log("Message received: "+msg);
io.sockets.emit(msg);
});
console.log('starting server on 8001...');
server.listen(8001);
My node js server console logs:
starting server on 8001...
Message received: from laravel
A: io.sockets.send(msg);
this worked for me. also make sure you are using the same version of socket.io on both client and server

Q: PHP site/script map with dependencies Just inherited a large PHP 5.3 site and wondered if there were some sort of crawler or site map tool that would identify the files and their dependencies.
A: You can determine PHP version and extension dependencies with PEAR's PHP_CompatInfo package. As for PEAR packages the app might be using, you can see what's installed using
pear list -a
I don't know of a tool that will tell you which external script dependencies are in use other than grep.

Q: Difference in the Validation and Evaluation Accuracy I am using pre-trained GoogLeNet and then fine tuned it on my dataset for classifying 11 classes. Validation dataset seems to give the "loss3/top1" 86.5%. But when I am evaluating the performance on my evaluation dataset it gives me 77% accuracy. Whatever changes I did it train_val.prototxt, I did the same changes in deploy.prototxt. Is the difference between the validation and evaluation accuracy is normal or I did something wrong?
Any suggestions?
A: In order to you get the fair estimation of your trained model on the validation dataset you need to set the test_itr and test_batch_size in a meaningful manner.
So, test_itr should be set to:
Val_data / test_batch_Size
Where, Val_data is the size of your validation dataset and test_batch_Size is validation batch size value set in batch_size for the Validation phase.

Q: Why check if value of an array is an array? I came across the following code in the book PHP Solutions, 2nd Edition
<?php
foreach ($_POST as $key => $value) {
// assign to temporary variable and strip whitespace if not an array
$temp = is_array($value) ? $value : trim($value);
// if empty and required, add to $missing array
if (empty($temp) && in_array($key, $required)) {
$missing[] = $key;
} if (in_array($key, $expected)) {
// otherwise, assign to a variable of the same name as $key
${$key} = $temp;
}
}
?>
My question is in regards to this line:
$temp = is_array($value) ? $value : trim($value);
If $value is the value held in the array (user inputted content from a form), why is it critical to determine whether or not the value is an array? Is it for security?
A: "why is it critical to determine whether or not the value is an array?"
Because trim expects a string and the function might not work when passing an array. It has nothing to do with security.

Q: Simple regex redirect not working I'm trying to setup a simple regex redirect. I have the following:
^.+?testurl\.com/folder-path/(\w+?$)/secondfolder
Which should then redirect to
http://www.testurl.com/folder-path/$1
This works if I don't add the /secondfolder to the end of the regex, but as soon as I add /secondfolder it doesn't work so I presume my syntax is wrong. Can anybody shed any light on what is wrong about the /secondfolder part of this?
Thanks!
A: $ denotes the end of the string (while ^ marks the start), so you should put it at the end of the string.
^.+?testurl\.com/folder-path/(\w+?)/secondfolder$

Q: Failed to bundle asset error with CDK + Lambda I have this project structure (where control is the name and root of my project):
control
|_ src
|_ control_loader -> this has a function inside called also control_loader
|_ utils
|_ some_helper_function.py
|_ __init__.py
|_ __init__.py
|_ lib
|_ some-cdk-where-i-declare-a-lambda.ts
|_ requirements.txt
Inside some-cdk-where-i-declare-a-lambda.ts I have this (among all the other necessary stuff):
new Function(this, `${this.appName}${this.stageName}ControlLambdaLoader`, {
code: Code.fromAsset(path.join(__dirname, '../src'), {
bundling: {
image: Runtime.PYTHON_3_8.bundlingImage,
command: [
'bash', '-c',
'pip install -r requirements.txt -t /asset-output && cp -au . /asset-output',
],
},
}),
runtime: Runtime.PYTHON_3_8,
handler: 'control_loader.control_loader',
vpc,
vpcSubnets: vpc.selectSubnets({
subnetType: SubnetType.PRIVATE_WITH_NAT,
}),
});
However, upon running cdk synth, I get the following:
(venv) PS C:\Users\rodri\Documents\control> cdk synth
npx: installed 15 in 1.145s
Bundling asset controlPipelineStack/controlBetaDeployStage/controlbetaStack/controlbeta/controlbetaControlLambdaLoader/Code/Stage...
Failed to bundle asset controlPipelineStack/controlBetaDeployStage/controlbetaStack/controlbeta/controlbetaControlLambdaLoader/Code/Stage, bundle output is located at C:\Users\rodri\Documents\control\cdk.out\asset.059c3b383943a1fadd3d933b670a7d351991e742d24a9785474b35c846267fde-error: Error: spawnSync docker EN
OENT
This is a very cryptic error. I know the bundling is done by docker to push the dependencies as a zip asset, but, any idea of where is this failing? I also tried to change the location of requirements.txt to inside src and that didn't help. I can deploy everything I remove the Lambda out. What am I doing wrong? Also, how do I make the bundle include some_helper_function.py as well?
Thanks!

Q: Implementing a scheduler for a backup program for a backup program I am doing I have already finished the GUI. Now I want to do the functional requirements. Each backup can have schedules. There are predefined settings like every Sunday or Monday but the user can also specify his own schedules.
As I have never done anything like this, I was wondering what a good approach would be to running a backup every x hours or days. I was thinking about using Threads or writing a service but both fields are totally new to me. What would be the best method here?
A: If threaded development and service development are both totally new then I think you will struggle to implement this in a useful way. Even so...
Scheduler-type applications are best run as services, because otherwise you need the user to be logged in to be running the application. Services run independently of the user being logged in.
Because of this, however, services don't have a user interface so your GUI needs to package up the details of schedule into a configuration file somewhere, then signal the service to re-load that configuration file so that the service will then know what to do and when to do it.
The service will normally spawn a worker thread to do pretty much everything, and that worker thread needs to be able to respond to the service being shut down (read up on AutoResetEvent to see how this might be done across threads). The thread will then wait until either an event or for the appropriate time to arrive and then do whatever it has to do.
None of this is actually complicated, but I suggest you do some digging into multithreaded programming first.
A: I agree with ColinM, Services are best for the Scheduler Type of application.
You have to combine the Services with application to run your code at scheduled intervals.

Q: Current Status of Sproutcore/Ember/Blossom/Sencha and Mobile devices (or alt frameworks) I've been looking over Sproutcore, Ember and Blossom and other competitive framework efforts (e.g. Sencha) to select for a HTML5 client side application project. The state, information, and documentation from these projects is a bit fragmented and in need of clarity, so I am presenting this to the community.
My project is to be a native-like HTML5 application with desktop level complexity in need of a complete application framework, that will work well on desktops and run with good speed on mobile devices with touch awareness. The widgets should be native-like (not web-like), but customizable so to be unique to the application.
Questions/framework Requirement:
*
*Native vs. Web style Applications. Framework should make it easy to
build native-like user experiences with the ability to make a custom
native feel (not just wholly imitating mac/win/iOS). Some of the text
surrounding Ember indicates it is really meant for web-style apps - which given no
UI layer maybe goes without saying. Frameworks like Sencha, can it easily accommodate custom widgets?
*Mobile Appropreatness. Framework should be appropreate for mobile devices and have facilities for touch input and
gestures.Several notes I've seen in my research indicate that Sproutcore and
Blossom aren't very appropreate for mobile, and that Ember is better
geared towards mobile (size?). It isn't clear whether the
touch/mobile libraries are very developed in Sproutcore/Blossom and if they will be supported it the
current state going forward. (and blossom compile to native is not acceptable). On the otherhand, Frameworks like Sencha, do they have the facility to work well on desktop as well as mobile?
*Framework Completeness. The framework should be a fairly complete application framework, with desktop-like OO expectations and management for automatically and efficiently syncing, managing, and serializing the data model with the server. Not sure if there is much difference between Ember and Sproutcore, how do other efforts like Sencha stack up?
A: Your question covers a lot of ground. I will pick some quotes and answer them directly.
My project is to be a native-like HTML5 application with desktop level
complexity in need of a complete application framework
Ember.js specifically bills itself as a "web-style" framework, not a an RIA framework. That said, you can build anything you want, but you would be trailblazing.
Sproutcore bills itself as an RIA framework. You have complete control over the DOM, so if you can do it in the browser, you can do it in Sproutcore.
Ext-Js is also a good application framework for desktops (Sencha Touch is for Mobile). If you like the way its examples look, then its a good choice. You can of course customize the dom and write your own widgets.
Blossom is basically Sproutcore with a canvas based view layer. It just went into beta, so you would definitely be trailblazing if you went with it.
So, you can basically use any of the frameworks you mentioned for the RIA part of your enterprise. I would eliminate Ember.js simply because the framework itself purposes itself for web-style (e.g. twitter) as opposed to RIA (e.g. iCloud) apps, which is not what you want.
The widgets should be native-like (not web-like), but customizable so
to be unique to the application.
All three of your remaining options can do this. If you like Senchas widgets, its a good choice. I don't know if they are native enough for you. That said, with any of the remaining frameworks you can customize the DOM to your heart's content.
Mobile Appropreatness. Framework should be appropreate for mobile devices
This is a tough one. Sencha Touch (which is separate but similar to Ext-Js) is very popular and gets the job done. It is performant too; a non-trivial app ran fine on my original Droid (which surprised me).
Sproutcore is very heavy weight. It has mobile support (i.e. for touch events) but you need to very careful about the dom you create, so as not to overwhelm the browser. I wouldn't choose Sproutcore for mobile, although you could if you are very careful.
and blossom compile to native is not acceptable
That does not seem reasonable to me. To be clear, NONE of these frameworks run natively on mobile devices; they ALL run in the browser. Blossom comes closes as the canvas API is mapped directly to the native API, giving you a truly native app. The only way you could get closer would be to use objective-c/java for iOs and Android.
So basically, at this point your left with Sencha(Ext-Js) and Blossom. Blossom is still in Beta, you would be trailblazing if you tried it. Sencha is established, has great support (Blossom support is good on irc), and a large developer base.
So Sencha is the choice, unless you really want to be cutting edge, and take a little risk.
A: Troy. Indeed, ember can run with another view layer framework such as jQuery Mobile which can provide a "app-like" look and feel.There is a github project: https://github.com/LuisSala/emberjs-jqm. In my view, if you need very cool animation you can use blossom.If you want to build a app, SC or ember should be OK. I'll choose ember because it 's loosely coupled.

Q: LINQ ignore incorrect type being assigned to property So, I have my own mapper (NOT AutoMapper) which maps models to each other. You give the model you'd like to map to, and with the Map method you push an object in. Beside of this I wrote the Extend method which functions as a override for the Map method to, for example, add properties which are not available in the object being mapped.
Problem:
The problem hereby is that my public Mapper<T> Extend(Func<T, T> func) method doesn't like the different types.
Possible solutions:
There are 2 solutions I'm thinking of:
*
*Ignore the error and map the value within my Extend method. Which isn't possible as far as I know due to the expression being executed immediately.
*Create a LINQ method which maps the value for me. Eg; q => q.Ownership = obj.Ownerships.First().Map().
Question:
How can I resolve this error and achieve what I want?

Q: Wrapper Function for a Recursive Function that takes a "pass by reference" value Here's the question: I'm trying to do,
Node* foo(Node *& ptr, other args) {
// some work here
}
In the wrapper function, I have to declare a temporary value (which is meaningless):
Node* wrapper( ... ) {
Node* p = nullptr;
return foo(p, other args);
}
Is there any way to get rid of the first line in the wrapper function? Thanks!!
A: I guess in foo you assign ptr some value (otherwise the *& has no value). You cannot pass nullptr and you have to declare a pointer like you shown in the wrapper because nullptr is an rvalue. An rvalue is an expression, or an "unnamed object" and you cannot take the address of it. There is more information here Why don't rvalues have an address?.

Q: GCC cosine optimization and sigbus I have a program that writes in some FPGA memory. When the program is compiled with optimizations (either O1, O2 or O3) it crashes with a bus error. However there is no crash when the program is compiled without optimizations.
Here is a minimal example which crashes:
void set_reg(const uint32_t *data)
{
uint32_t val = data[0];
dvm.write32(dac_map, 0, static_cast<uint32_t>(8192 * cos(val))); // crash
}
When I add volatile there is no more crash:
void set_reg(const uint32_t *data)
{
volatile uint32_t val = data[0];
dvm.write32(dac_map, 0, static_cast<uint32_t>(8192 * cos(val))); // no crash
}
If I remove the call to cos there is no problem.
This seems related to GCC: program doesn't work with compilation option -O3. When I add the flag -ffloat-store the program don't crash.
However, on the actual code which is more complicated, adding the flag -ffloat-store doesn't solve the problem.
I don't understand the kind of optimization GCC does and how this leads to a SIGBUS. If anyone could explain that, it would be useful for debugging.
Thank you.
NB:
1) GCC version is arm-linux-gnueabihf-g++ (Ubuntu/Linaro 5.3.1-14ubuntu2) 5.3.1 20160413
2) The function write32 is defined as
void write32(MemMapID id, uint32_t offset, uint32_t value)
{
ASSERT_WRITABLE
*(volatile uintptr_t *) (GetBaseAddr(id) + offset) = value;

Q: split textarea value properly jQuery regex I am having problems to properly split textarea value. My current snippet split each line that starts with "-" and displays it as value of span element, but, it wont collect next line value which does not start with "-".
For example if I paste this text into textarea:
- first match
rest of first match
- second match
- third match
Script should output:
<span style="color:red;">- first match rest of first match </span><br>
<span style="color:red;">- second match</span><br>
<span style="color:red;">- third match</span><br>
$(document).ready(function() {
const regex = /^\s*-\s*/;
$("#txt").keyup(function() {
const entered = $('#textarea').val()
const lines = entered.split(/\n/);
let spans = "";
for (const line of lines) {
if (regex.test(line)) {
spans += "<span style='color:red;'>- " + line.replace(regex, '') + "</span><br/>";
}
}
$(".results").html(spans);
});
});
.row {
background: #f8f9fa;
margin-top: 20px;
padding: 10px;
}
.col {
border: solid 1px #6c757d;
}
<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>
<div class="container">
<div class="row">
<div class="col-12">
<form>
<textarea id="textarea" rows="5" cols="60" placeholder="Type something here..."></textarea>
</form>
</div>
<div class="col-12 results"></div>
</div>
</div>
So, basically script should split textarea value from line that starts with "-" until next line which starts "-".
Code snippet is also available here: https://jsfiddle.net/zecaffe/f7zv3udh/1/
A: Why not just a split to the \n-?
$(document).ready(function() {
$("#textarea").keyup(function() {
const entered = $('#textarea').val()
const lines = entered.split(/\n-/);
let spans = "";
lines.forEach((l,i)=>{
// remove the first -
if(i===0 && l[0]==="-") l = l.slice(1)
spans += "<span style='color:red;'>- " + l + "</span><br/>";
})
$(".results").html(spans);
});
});
.row {
background: #f8f9fa;
margin-top: 20px;
padding: 10px;
}
.col {
border: solid 1px #6c757d;
}
<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>
<div class="container">

Q: ansible.vars.unsafe_proxy.AnsibleUnsafeText object' has no attribute 'private_ip' From: Best way to launch aws ec2 instances with ansible
- name: Add the newly created EC2 instance(s) to the local host group (located inside the directory)
local_action: lineinfile
dest="/etc/ansibles/aws/hosts"
regexp={{ item.private_ip }}
insertafter="[webserver]" line={{ item.private_ip }}
with_items: "{{ ec2.instances }}"
creates this error:
fatal: [localhost]: FAILED! => {
"failed": true,
"msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: 'ansible.vars.unsafe_proxy.AnsibleUnsafeText object' has no attribute 'private_ip'\n\n
I have defined variable private_ip: under vars , with a value
A: I think that the private_ip property in the code above references to the property of the ec2 variable that's used to catch the returned values from the ec2 module (from the last step), no the one that you defined elsewhere.
- name: Launch the new EC2 Instance
local_action: ec2
group={{ security_group }}
instance_type={{ instance_type}}
image={{ image }}
wait=true
region={{ region }}
keypair={{ keypair }}
count={{count}}
register: ec2 (this is where the variable is defined!!!)
Essentially Ansible is complaining that the ec2 variable hasen't got the
attribute 'private_ip'
, so check the preceding code and see how that variable gets defined.
In the example above you're trying to get the private_ip address from aws. Is that really what you want? Most of the time you want the public ip address since that's what you will use to connect to the ec2 machine, provision it, deploy your app etc...

Q: Message/Folder permissions Is there a way to change folder and/or message permissions?
I noticed that folders created on root folder of a user, are not visible - is this a bug or a feature?
Thank you.
A:
I sent a POST request with: URL= outlook.office.com/api/v2.0/me/MailFolders/root/childfolders content inside: { "DisplayName": "ExampleName" } The folder was created successfully, and reachable via API's. However it is not visible in the Outlook WebUI nor in the Outlook application. Is this by design? –
The end-point for the root folder is incorrect, there is no need to use the “root” keyword. And this end-point give the error when I try to create a folder.
Here is an sample to create a folder under the root folder for your reference:
POST: https://outlook.office.com/api/v2.0/me/MailFolders
Header:
authorization: bearer {token}
content-type: application/json
BODY:
{"DisplayName":"FolderName"}
And we will the 201 status code and response like figure below:

Q: calculate values In an order form, each row has 3 fields: quantity, price, total.
How do I create a function that on changing a number the subtotal is calculated and so is the total?
Can anyone suggest a way?
A: You'd need to add a listener to each row so that when the price or quantity are updated, you can get the new quantity and price and update the total column.
In jQuery, something like:
$('.row').on('change', function() {
var quantity = $('.quantity', this).val(), // get the new quatity
price = $('.price', this).val(), // get the new price
total = price*quantity;
$('.total', this).val(total); //set the row total
var totals = $.map($('.row .total'), function(tot) {
return tot.val(); // get each row total into an array
}).reduce(function(p,c){return p+c},0); // sum them
$('#total').val(totals); // set the complete total
});
This assumes that each order form row container has the class row, each quantity has the class quantity, each row total has the class total and the order form total has the id total.

Q: published bot on skype but it's not working I have a bot that I've created by merging LUIS and QnA together in a single project using Microsoft Bot Builder.
I published the bot to an EC2 instance from visual studio and I'm using the Bot Framework Emulator for testing and it works perfectly. (MUST use ngrok for tunneling).
Now I want to deploy the bot on Skype. I logged into the Bot Framework Portal and I registered my bot. Now comes the configuration part.
I'm not quite sure what to set as the HTTP endpoint here.
I found this in the Bot Framework documentation:
Complete the Configuration section of the form.
Provide your bot's HTTPS messaging endpoint. This is the endpoint
where your bot will receive HTTP POST messages from Bot Connector. If
you built your bot by using the Bot Builder SDK, the endpoint should
end with /api/messages.
*
*If you have already deployed your bot to the cloud, specify the endpoint generated from that deployment.
*If you have not yet deployed your bot to the cloud, leave the endpoint blank for now. You will return to the Bot Framework Portal
later and specify the endpoint after you've deployed your bot.
When I published from Visual Studio, from the Azure App Service Activity windows, I found this line:
Start Web Deploy Publish the Application/package to https://ec2-00-000-000-00.compute-1.amazonaws.com:PORT/msdeploy.axd?site=bots ...
I used that address for the Messaging Endpoint in the configuration and I published my app. However when I'm testing it on Skype, i'm not receiving any messages from the bot.
I don't know what the problem is exactly, does this have something to do with ngrok? Or am I missing a step here, is there something else I should be doing to deploy the bot on Skype? Maybe something to do with the appid/password that I need to use ... i really don't know
Would really appreciate an explanation of how this works exactly. I don't really understand how the whole deployment procedure works exactly, feels like i'm swimming in murky waters.
A: Your endpoint is going to be the root of your deployed web application instance, plus the route that your bot is listening on.
For example, one of my bots is deployed to the free version of Azure Web Sites. The URL for a site such as this is https://APPLICATION_NAME.azurewebsites.net and the route that the bot listens on is the default /api/messages. This makes the endpoint https://APPLICATION_NAME.azurewebsites.net/api/messages.
If you connect directly to your app's endpoint, you should at least get a JSON dump with an error message. To make sure your site is getting deployed, drop an HTML file into the root of EC2 and see if you can access this.

Q: Posting on same form in JSP I want to search for a product...so I have made a form...
but my products are being retreived in the doGet() method
and when I search for a product, the doPost() method is called....
SO what should i Do?
A: It's actually unclear what your problem is. If you want the form submit to be idempotent/bookmarkable, then just remove method="post" from the HTML <form> element if you want the request to be bookmarkable. Don't forget to remove doPost() method from the servlet as well.
Or if you actually want to let the form submit to a different servlet, then just create another servlet, register/map it the same way but on a bit different URL pattern and finally change the action URL of the HTML <form> element.

Q: Custom Gradle Plugin Exec task with extension does not use input properly I am following the Writing Custom Plugins section of the Gradle documentation, specifically the part about Getting input from the build. The following example provided by the documentation works exactly as expected:
apply plugin: GreetingPlugin
greeting.message = 'Hi from Gradle'
class GreetingPlugin implements Plugin<Project> {
void apply(Project project) {
// Add the 'greeting' extension object
project.extensions.create("greeting", GreetingPluginExtension)
// Add a task that uses the configuration
project.task('hello') << {
println project.greeting.message
}
}
}
class GreetingPluginExtension {
def String message = 'Hello from GreetingPlugin'
}
Output:
> gradle -q hello
Hi from Gradle
I'd like to have the custom plugin execute an external command (using the Exec task), but when changing the task to a type (including types other than Exec such as Copy), the input to the build stops working properly:
// previous and following sections omitted for brevity
project.task('hello', type: Exec) {
println project.greeting.message
}
Output:
> gradle -q hello
Hello from GreetingPlugin
Does anyone know what the issue could be?
A: It is not related to the type of the task, it's a typical << misunderstanding.
When you write
project.task('hello') << {
println project.greeting.message
}
and execute gradle hello, the following happens:
configuration phase
*
*apply custom plugin
*create task hello
*set greeting.message = 'Hi from Gradle'
executon phase
*
*run task with empty body
*execute << closure { println project.greeting.message }
in this scenario output is Hi from Gradle
When you write
project.task('hello', type: Exec) {
println project.greeting.message
}
and execute gradle hello, the following happens
configuration phase
*
*apply custom plugin
*create exec task hello
*execute task init closure println project.greeting.message
*set greeting.message = 'Hi from Gradle' (too late, it was printed in step 3)
the rest of workflow does not matter.
So, small details matter. Here's the explanation of the same topic.
Solution:
void apply(Project project) {
project.afterEvaluate {
project.task('hello', type: Exec) {
println project.greeting.message
}
}
}

Q: How to obtain enrollment certificate from CA in PHP I'm writing a service that is supposed to receive DER format PKCS#10 certificate request in Base64 encoding from mobile device and then return certificates obtained from CA.
I'm trying to use "https://CA-server/certsrv/mscep/mscep.dll?operation=PKIOperation&Message=urlencoded request"
$ca_link_device="https://..../certsrv/mscep/mscep.dll";
$URL=$ca_link_device."?operation=PKIOperation&Message=".urlencode($BinarySecurityToken)."=";
$ch3 = curl_init();
curl_setopt($ch3, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch3, CURLOPT_URL, $URL);
curl_setopt($ch3, CURLOPT_HEADER, 0);
$cert = curl_exec($ch3);
but the data that is returned contains empty envelope. I'm most probably doing something really dumb, but unfortunately my knowledge in certificate management is close to zero. I have been trying to google around, but there are so many technical documents around that I don't know from where to start and what is relevant to me and what is not.
All help much appreciated.
Edit: According to one documentation I should wrap my PKCS10 request into PKCS7. According to Microsoft PKCS10 should be fine and PKCS7 is only used for certificate renewal. Who to believe?
A: In the end we just droped the mscep.dll approach and used curl to directly send POST with needed parameters to ...certsrv/certfnsh.asp page. Then we parsed the returned HTML and obtained the link for certificate download.
Not a nice solution, but worked for us.

Q: How to create this in flutter enter image description here
I have tried different ways like transform and rotation but not able do it
A: I think you've been getting some downvotes because you didn't share any of your previous attempts, on which the solution could be built.
I think what you might want to do is use a CustomClipper to create the desired shape. I wrote you a simple one that makes a wedged shape with just 4 points, but you can use Path.arc to make it more like the image you provided:
class WedgeClipper extends CustomClipper<Path> {
final bool isRight;
WedgeClipper({this.isRight = false});
@override
Path getClip(Size size) {
Path path = Path();
// mirror the clip accordingly when it's left or right aligned
if (isRight) {
path.addPolygon([
Offset(0, size.height / 4),
Offset(size.width, 0),
Offset(size.width, size.height),
Offset(0, 3 * size.height / 4)
], true);
} else {
path.addPolygon([
Offset(0, 0),
Offset(size.width, size.height / 4),
Offset(size.width, 3 * size.height / 4),
Offset(0, size.height)
], true);
}
return path;
}
@override
bool shouldReclip(covariant CustomClipper<Path> oldClipper) {
return true;
}
}
Then to use it in your code, you can do something like:
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Wedge List View'),
),
body: ListView.builder(
itemBuilder: (context, index) {
bool isRightAligned = index % 2 == 0;
return Padding(
child: ClipPath(
child: Material(
child: SizedBox(
height: 80,
width: double.maxFinite,
child: Row(
mainAxisAlignment: isRightAligned ? MainAxisAlignment.end : MainAxisAlignment.start,
children: isRightAligned ? [
Text('Tile to the right side'),
SizedBox(width: 10),
Image.network('https://upload.wikimedia.org/wikipedia/commons/b/b1/VAN_CAT.png'),
] : [
Image.network('https://upload.wikimedia.org/wikipedia/commons/b/b1/VAN_CAT.png'),
SizedBox(width: 10),
Text('Tile to the left side'),
],),
),
color: Color(0xffdddddd),
),
clipper: WedgeClipper(
isRight: isRightAligned), // alternating left/right clips
),
padding: EdgeInsets.symmetric(horizontal: 8.0),
);
},
),
);
}
It basically draws a rectangle, clips it with the CustomClipper and renders what's left.
The result looks like this:

Q: Inserting image to database I am trying to fetch image from the database, insertion of images are successful but are not displaying when I fetch it.
Here's my code for uploading image
include("p1-connect.php");
if(isset($_POST['upload'])){
$file = $_FILES['picture'];
$fileName = $_FILES['picture']['name'];
$fileTmpName = $_FILES['picture']['tmp_name'];
$fileSize = $_FILES['picture']['size'];
$fileError = $_FILES['picture']['error'];
$fileType = $_FILES['picture']['type'];
$fileExt = explode('.', $fileName);
$fileActualExt = strtolower(end($fileExt));
$allowed = array('jpg','jpeg','png'); //allowed file types
if(in_array($fileActualExt,$allowed))
{
if($fileError === 0){
if($fileSize < 1000000){
$fileNameNew = uniqid('',true).".".$fileActualExt;
$fileDestination = 'uploads/'.$fileNameNew;
$query = "INSERT INTO image(image,image_name) VALUES('$fileName','$fileTmpName')";
mysqli_query($connect,$query);
$images = addslashes(file_get_contents($_FILES['picture']['tmp_name']));
move_uploaded_file($fileTmpName, $fileDestination);
}else{
echo "Your file is too big";
}
} else{
echo "An error uploading your files";
}
} else{
echo "You cannot upload files of this type";
}}
For fetching the image
<body>
<form method="post" action="" enctype='multipart/form-data'>
<input type='file' name='picture' />
<input type='submit' value='Upload Image' name='upload'>
<?php
$sql = "SELECT * FROM image";
$result =mysqli_query($connection,$sql);
while($row = mysqli_fetch_array($result)){
$imagee = $row['image'];}
?>
<tr>
<td><img src="<?php echo $imagee; ?>" width="175" height="200"/></td>
</tr>
</form></body>
Only broken image icons are showing
My 'image' table includes:
id - int
image - blob
image_name - varchar
Thank you in advance
