Code of proc.h.
The S of SWTED probably means stat. What about WTED? Is it the abbreviation of word watched?
In UNIX 7 the SWTED flag is used in two places:
Inside ptrace(), the SWTED flag is cleared before running the child process
ptrace()
{
...
p->p_flag &= ~SWTED;
setrun(p);
...
}
Inside wait(), if the process is stopped (traced) and the SWTED flag is cleared, then flag will be set, and its PID and signal passed back.
wait()
{
...
if(p->p_stat == SSTOP) {
if((p->p_flag&SWTED) == 0) {
p->p_flag |= SWTED;
u.u_r.r_val1 = p->p_pid;
u.u_r.r_val2 = (fsig(p)<<8) | 0177;
return;
}
continue;
}
...
}
That means SWTED is set when a traced process is used in wait(), thus most likely meaning waited. (SWAIT already exists so the name can't be used.)

Hi I try to call some data using API but it shows error message of "invalid key". But In the function I didn't figure out where I can input my key. The code is shown below:
sahie_years <- getCensus(
name = "timeseries/healthins/sahie",
vars = c("NAME", "PCTUI_PT"),
region = "state:01",
time = "from 2006 to 2018")
head(sahie_years)
Can anybody have some ideas?
See documentation here for setting up your API key.
You need to sign up for an API key here.
Once you've done that you can either specify your API key by setting an environment variable using Sys.setenv(CENSUS_KEY="YOUR_CENSUS_KEY_GOES_HERE"), or
just set it directly in your getCensus call by adding the argument key = "YOUR_CENSUS_KEY_GOES_HERE".
For API keys in general, it is often easiest to set them in a .Renviron file, which will make them available in each session using Sys.getenv.

I have a users object, in that I am trying to update a specific node(status) by using the firebase update(payload) method. But when I try to do that, instead of updating the value in the parent node, it creates a new child node(duplicate node) with the value being updated there.
let firebaseApp = firebase.initializeApp(firebaseConfig);
let uniqueID = "OEHCrSnKFrd87JDivvA0sLMnj8u1"
firebaseApp.database()ref("users/" + uniqueID).update({
status: false
})
Duplicate node image
On .update() you have to specify the path for the key.
try the following:
let firebaseApp = firebase.initializeApp(firebaseConfig);
let uniqueID = "OEHCrSnKFrd87JDivvA0sLMnj8u1"
let updates = {};
updates["/status"] = false;
firebaseApp.database()ref("users/" + uniqueID).update(updates)

I want to delete particular 'like'id node(with details),on click of dislike button. I am using android app.
We don't know the platform but the answer is very similar
let ref = myRootRef.child("likes")
.child("-K_4Fbj0wBmZf3_l-uXe")
.child("-K_4FdjaJgPoR0EGwexB")
ref.removeValue()
you can also delete data by setting using ref.setValue and setting it to nil.
I think that you have structured your data wrongly. You want to use on("child_added") on "likes". Once you have all childs,
you want to delete a child via user input (e.g. you have a delete button with the referense to the current key)
When storing: ref("likes").push()
When retrieving: ref("likes").on("child_added")
In the data viewer (what you're looking at) you can hover over a node and you'll have the ability to add a new child (green + button) or delete the node (red X button).

How to try to use ban message from device if The message is same .
I want to get message from device like "OK" While it is connect . Then it will respond to me message "OK" . Device permenently send me message "OK" after send new message. How can I avoid this message.
var list = new List<string>();
...
// in the loop or other repeating code
list.Add("OK");
...
// at the end of code
var summary = string.Join(". ", list.ToArray());
gotNewmesage(summary);
Istead of showing a message directly, collect all messages and show them at the end of the action/method.
Example:
var list = new List<string>();
...
// in the loop or other repeating code
list.Add("OK");
...
// at the end of code
var summary = string.Join(". ", list.ToArray());
gotNewmesage(summary);
If you want to avoid duplicates, check it before adding a message, for example
if (!list.Contains("OK"))
list.Add("OK");

I'm using fr3dLdapBundle with fosUserBundle.
Symfony - version=v2.0.9
fosUserBundle - version=1.2.0
I have done everything as typed in the installation documents. But I catch one error.
ErrorException: Notice: Undefined offset: 0 in ...\vendor\bundles\FR3D\LdapBundle\Ldap\LdapManager.php line 27
Can you give me advice on what to do?
The Ldap field for identify a single entry is not the default value setted or is not the first in the config.
At config.yml
attributes:
- { ldap_attr: uid, user_method: setUsername }
Means uid will be the Ldap Attribute used for identify a user by his username in the login form.
This entry must match with your Ldap Attribute and must be the first in the list after attributes
