Cavani to make first PSG start since August
PARIS, Nov 9 — Edinson Cavani is set to make his first start for Paris Saint-Germain since August against Brest today after recovering from a hip injury, coach Thomas Tuchel said on yesterday.
“He should play tomorrow, we need him to start playing,” Tuchel said ahead of the weekend’s clash.
Cavani has been absent from the French champions’ starting line-up thanks to a combination of the persistent injury and the hot form of new arrival Mauro Icardi.
He has made substitute appearances in PSG’s last two Ligue 1 matches against Marseille and at Dijon, as well as their midweek Champions League win over Club Brugge.
Tuchel added that the Uruguayan, who is PSG’s all-time leading scorer with 195 goals, is “disappointed” to have slipped back in the attacking hierarchy, but is in a “good state of mind”.
The German said that he was unsure whether in-form Icardi would take part after picking up a knock to his left foot after scoring the winner in the 1-0 victory over Brugge.
The Argentine has stolen the show in recent weeks with eight goals in his last seven appearances in all competitions.
“I don’t know about Mauro yet, he was in a lot of pain after the match,” said Tuchel. “We need to see if he will be able to play.”
World Cup-winner Kylian Mbappe misses the trip to Brittany with a leg problem he suffered in the midweek European win over Club.
Tuchel also confirmed Neymar’s continued absence today following the hamstring injury he suffered playing for Brazil last month.
Thilo Kehrer, Ander Herrera and Thomas Meunier are also all out.
PSG have a six-point lead at the top of Ligue 1 despite losing 2-1 at Dijon last time out. — AFP

'3 Black Chicks Review...'
28 DAYS (2000) Rated PG-13; running time 103 minutes Genre: Dramedy IMDB site: http://us.imdb.com/Details?0191754 Official site: http://www.sony.com/28days/ Written by: Susannah Grant Directed by: Betty Thomas Starring: Sandra Bullock, Dominic West, Viggo Mortensen, Azura Skye, Elizabeth Perkins, Reni Santoni, Alan Tudyk, Mike O'Malley, Steve Buscemi, Marianne Jean-Baptiste, Diane Ladd
Review Copyright Rose Cooper, 2000 Review URL: http://www.3blackchicks.com/bams28days.html
"Break it up, folks; nuthin' to see here..."
The Story (WARNING: **spoilers contained below**): Gwen (Sandra Bullock) parties like it's 1999; a drink in one hand and pills in the other, Gwen and her boyfriend Jasper (Dominic West) go on a bender and trash the wedding of Gwen's long-suffering sister Lily (Elizabeth Perkins), topping off the day by crashing a "borrowed" limo.
Sentenced to rehab for 28 days [clever title then, har har!], Gwen is made to Confront Her Inner Demons alongside other rehab residents, including her young, confused roommate Andrea (Azura Skye), resentfully-scarred Daniel (Reni Santoni), big lug Oliver (Mike O'Malley), Comic Relief/Sensitive Guy Gerhardt (Alan Tudyk), ObBlackResident Roshanda (Marianne Jean-Baptiste), addict and celebrity baseball player Eddie Boone (Viggo Mortensen), and even her ex-addict counselor Cornell (Steve Buscemi)--all learning to Live Life One Day At A Time.
And oh yeah: Wackiness Ensues.
The Upshot: One of these days, I'd like for someone to explain to me just what the difference between Julia Roberts and Sandra Bullock is. Besides the $20mil per ploddingly dull picture that Roberts gets and Bullock doesn't, I just don't see it. But then again, I'm not the target demo for either of these chicks. Slot-A Roberts could've easily been plugged into this Hole-B flick without it missing a beat, and the only difference would be that 28 DAYS would've come away with a gazillion-dollar first day box office draw. And I would've slept through her version, too.
There was one--count 'em, one--scene in this entire movie that wound up surprising me, and that came at the very end; keeping it as spoiler-free as I can, I'll just say that it has to do with whom Gwen didn't Walk Off Into The Sunset with.  No one here, not even Comic Relief/Sensitive Guy Gerhardt, was anywhere near original; other than being a pretty bad poster for the Just Say No types, 28 DAYS did nothing to earn its keep.
Well, that's not quite true.  Pity that these bits were lost within a flick unworthy of these moments of ingenuity.
Bammer's Bottom Line: A situation comedy without the laughs, disguised as a drama, that wound up a Tragedy. Made for a good sleeping pill, though.
28 DAYS (rating: yellowlight): zzzzzzzzzzzzzz...

Provides several methods for computing the Quantile Treatment Effect (QTE) and Quantile Treatment Effect on the Treated (QTT). The main cases covered are (i) Treatment is randomly assigned, (ii) Treatment is as good as randomly assigned after conditioning on some covariates (also called conditional independence or selection on observables) using the methods developed in Firpo (2007) <doi:10.1111/j.1468-0262.2007.00738.x>, (iii) Identification is based on a Difference in Differences assumption (several varieties are available in the package e.g. Athey and Imbens (2006) <doi:10.1111/j.1468-0262.2006.00668.x> Callaway and Li (2017) <https://ssrn.com/abstract=3013341>, Callaway, Li, and Oka (2017) <arXiv:1702.03618>).

Manually halt the cutter process
Sometimes, a globe cutting procedure might be interrupted from the GEE Portable Globe Cutting web page. This can result in a "runaway" or "zombie" process on the system that hosts the Portable Globe Cutter tool. These processes must be halted at the operating system level.
The GEE Portable Globe Cutting system uses the command line tools listed below. You can search for these as processes on the operating system:
/opt/google/bin/gepolygontoqtnodes
/opt/google/bin/gerewritedbroot
/opt/google/bin/gekmlgrabber
/opt/google/bin/geportableglobebuilder
/opt/google/bin/geportableglobepacker
/opt/google/gehttpd/cgi-bin/globe_cutter.py
You can use either of these methods to halt the processes from the command line:
- Invoke the Linux
top
command and look for any of the command line tools in the active process list. To stop the processes directly from thetop
command, press the k key and enter the process id number. - Invoke the Linux
ps
command and search for any of the command line tools. For example:ps aux | grep geportable
. If you find a process, you can halt it with thekill
command:kill -9 process id


Varia Radar Light
It’s been on my wish list for a while, but I finally purchased a Varia Radar Light (Varia RTL515) recently from Amazon, as it was on offer.
However, I didn’t keep it very long and it was used for a day before returning.
Perhaps I was expecting too much of it or that my use case wasn’t the best example of it.
 In my case, I was using the Garmin Edge 530, which supports it natively, though I did download the My Bike Radar app via Connect IQ store.
Once the device is connected, it alerts you to cars coming up behind you with a sound notification and a graphic on the right hand side of the head unit showing the car getting closer to you. Ray at DC Rainmaker has an excellent review of if here.
Use Case
My use case was to use it when cycling to work. My route is a mix of bike path and roads, with the majority being road.
The device worked - I would get a notification of the car behind me. However, there were occasions where the car wasn’t detected until quite late and I could already see the car out the corner of my eye. This is obviously not great and I’m not sure if the positioning was wrong, as this doesn’t appear to be the view of everyone else that has used the device.
The other major issue I had with the device was getting false positives when cycling on a segregated cycle path - the device is smart (from a radar point of view) but it doesn’t differentiate from traffic that is directly behind and traffic that is 3-4m off to the side, as I was picking up cars driving down the road that were of no danger to me.
As I bought primarily for commuting, this wasn’t that helpful, as there are a number of paths like this on my route.
In the end, I returned the device, and ended up purchasing a mirror instead…
Significantly cheaper, the mirror has been been working well enough for me that I can see behind me and provide me with some warning of the cars behind me.
Perhaps if I was to put the Varia on my weekend bike and use that for rides, but at the minute, that isn’t something that I’m doing a lot of, so that would be a lot of money for not a lot of benefit at this point in time.

This Ofsted survey report follows concerns raised in the Ofsted Annual Report 2012/13 about low-level disruption in schools. As a consequence, guidance to inspectors was tightened to place greater emphasis on this issue in routine inspections. This survey was commissioned to ascertain the nature and extent of low-level disruptive behaviour in primary and secondary schools in England.
The findings from that survey show that teachers, parents and carers are rightly concerned about the frequent loss of learning time through low-level but persistent disruptive behaviour. This report demonstrates that, in too many schools, teachers are frustrated by this sort of behaviour and are critical of colleagues, particularly those in leadership positions, who are not doing enough to ensure high standards of pupil behaviour.

Hey there, not sure how active this forum is anymore, but...
I'm playing on a server that I'm pretty fond of and I happen to just have an amazing whip on this server. I do not want to whip to go to waste, but haven't heard of any builds, built around a whip. Can anyone help me out?
Thanx in advance.
Id say that you should make a shifter and take weapon profiency exotic, then let the item bonuses merge with the shifter weapon.
Could you post the specs of the whip?
Also, what were you thinking of for use? High damage? Just for show? or like suggested, shifter for itm merge?
I thought about your request at work today and i came up with an idea of a dex based whipmaster. Check it in the build forum (dwarf assassins' whip master).

ONE MAGIC CHRISTMAS A film review by Andrew Hicks Copyright 1996 Andrew Hicks / Fatboy Productions
(1985) * (out of four)
The only thing magical about this disgustingly sappy Disney movie is the tremendous sense of relief one gets when the end credits finally roll!  The whole plot of this movie concerns a woman with a complete humbug attitude about Christmas, and after seeing this awful movie, I feel the same.
One year around Christmastime, an angel appears to the cute little daughter of the humbug woman and saves her from the path of a speeding car. Gideon's the guy's name, and -- get this -- he's working for Santa Claus. I guess he was laid off by God or something. They try to give her the "Christmas Spirit," although personally, I think that inebriated angel has been drinking too many of the "Christmas Spirits," if you know what I mean.
And some Christmas this woman has, too. She's fired from her supermarket checker job (Oh no! However will the family survive without mom's $4.15 an hour?!), her husband is shot and killed by a bank robber, and her kids are kidnapped by the same bank robber, who eventually drives off a bridge. Miraculously enough, Gideon is able to save the kids, but -- surprisingly enough -- he can't save the father from being shot. He recommends someone who might be able to help. That's right, the big guy upstairs -- Santa Claus himself.
But they find out Santa may be omniscient and omnipresent (you know how fat he is!), but he's not omnipotent, meaning he can't bring people back from the dead. He tells her only the mother can do that, asking her if she believes in magic. Personally, I don't, but I do believe this movie stinks.

I have just upgraded emoncms to the latest level, after quite a bit of hassle with GIT and deletion/recreation of the database I am getting there.
There is however 1 issue I can get passed, when I log onto the emoncms server the only options I appear to have are:-
Raspberry Pi, Dashboard, Admin, Account, Logout.
The input/feeds option is not appearing.
Any idea's out there ?
Re: Emoncms upgrade issue's
Hello Neil, that's a strange one, if you see dashboard and raspberrypi then inputs and feeds should also be there. Did you make any changes to those modules? does the script /emoncms/Modules/input/input_menu.php exist?
I'd do another git clone of emoncms, maybe rename your current folder to something like emoncms_tmp and pull a clean copy:
git clone http://github.com/emoncms/emoncms.git
Re: Emoncms upgrade issue's
Hi Trystan, Thanks for that, for some reason input_menu.php didnt exist even though Git said there was nothing more to update. I took your advice and reloaded the emoncms software from scratch and now it appears to work.
Thanks for you help.
btw, not sure if this will help or not and it's totally off topic, but ever since upgrading emoncms to the new version rather strangely my GLCD has started to run constantly without locking up regulary, I havent upgraded to the newest level of GLCD software either, so I am thinking atleast part of the problem could be down to the constant transmitting of the time clock. I have used the new level of emoncms to only update the time every 10 minutes which is probably still too often, but it does appear to have cut down of GLCD lockups.
Re: Emoncms upgrade issue's
Hello Neil, that's interesting about the EmonGLCD, good to hear, could the latest emonglcd firmware and a slower time update rate mean no lockups at all maybe, Glyn's pretty positive about the latest firmware..
Re: Emoncms upgrade issue's
Perhaps had you erased input_menu.php accidentally and when pulling, git automatically merged this "change" in the new version.
To know where you are, you can use the command
git status -s
It will indicate the changes you made locally.
You can undo (and lose) your changes by doing a git checkout on every locally modified file.

SubLime is a tool to overlay subtitles loaded from an SRT file over an HTML5 video element in your browser. It is available as a
It is known to work with YouTube, Netflix and vimeo videos (if HTML5 video is used).
In case there's more than one video on a webpage, just pressing the Chrome extension button again, or running the bookmarklet again, should move the subtitles to the next video.
There's also a small tool which can play local video files (supported video formats will depend on your browser):

In case the subtitles from your file are not well synchronized to the time of the
video, you can resync them in a number of ways. Let's call v
the video time and
s
the subtitle time, then a time offset o
and time scale factor f
can be
set. For a specific video time v
, the corresponding time looked for in the
subtitle file is then
s(v) = v/f+o
Alternatively, the subtitle time s
will be shown at video time
v(s) = (s-o)*f
The values of o
and f
can be set directly, or can be calculated by matching the
subtitles to the video at two times, pressing 'k' and 'l' respectively at each time.

Except for the key to open the preferences dialog, all key bindings are configurable.
For YouTube, Netflix and vimeo videos, going to full screen should preserve the subtitles. In case of problems, it may be possible to instruct your browser to make its window as large as possible (e.g. by pressing F11 or going to 'Presentation Mode').

We created an alternative platform for dance lovers who would like to have partners to enjoy the amazing dance events with. There are applications such as "meetup.com" or "eventbrite.com" where you can see hundreds of dance events. If you do not have a partner, it makes no sense to join those dance events. Also, there are various matching platforms such as sportpartner.com where you can search for partners. But it makes no sense to find a dance partner if there is no dance event you can go with. Besides, it is time-consuming to search for ideal partners on those websites.
How does DanceWitnMe differentiate from other applications? We present dance events on your profile page, while our powerful matching engine finds the best partner for you! From now on you don't need to waste your precious time searching for dance events and partners!

You can usually do things to ease shoulder pain yourself. See a GP if it does not start feeling better after 2 weeks.
You usually need to do these things for 2 weeks before shoulder pain starts to ease.
It can take 6 months or longer to recover from shoulder pain.
stay active and gently move your shoulder
try shoulder exercises for 6 to 8 weeks to stop pain returning – the Chartered Society of Physiotherapy has exercises for shoulder pain
stand up straight with your shoulders down and gently back
sit with a cushion behind your lower back
rest your arm on a cushion in your lap
use pain relief so you can keep moving – try painkillers like paracetamol and ibuprofen, and heat or cold packs
do not completely stop using your shoulder – this can stop it getting better
do not do things that seem to make it worse
do not make up your own strenuous exercises or use heavy gym equipment
do not slouch when sitting – do not roll your shoulders or bring your neck forward
Try either a:
They may suggest:
These can be signs of something serious, like a broken or dislocated bone, or a torn (ruptured) ligament or tendon.
111 will tell you what to do. They can tell you the right place to get help if you need to see someone.
Go to 111.nhs.uk or call 111.
A GP will examine you to work out what's causing your shoulder pain.
They might send you for tests (such as an X-ray) to check the cause.
They'll suggest a treatment based on the cause, for example:
The number of physiotherapy sessions a GP might prescribe depends on the cause of your shoulder pain.

They might prescribe more physiotherapy or suggest another treatment.
Physiotherapy from the NHS might not be available everywhere. Waiting times can also be long.
You can also pay to get physiotherapy privately.
Shoulder pain that does not improve after 2 weeks might be caused by something that needs treatment.
Do not self-diagnose – see a GP if you're worried.
| Shoulder symptoms | Possible causes |
|---|---|
| Pain and stiffness that does not go away over months or years | frozen shoulder, arthritis (osteoarthritis or rheumatoid arthritis) |
| Pain that's often worse while using your arm or shoulder | tendonitis, bursitis, impingement |
| Tingling, numb, weak, feels like it's clicking or locking | shoulder instability, sometimes because of hypermobility |
| Sudden very bad pain, cannot move your arm (or it's difficult), sometimes changes shape | dislocated shoulder, broken bone (such as the upper arm or collarbone), torn or ruptured tendon |
| Pain on top of the shoulder (where the collarbone and shoulder joint meet) | problems in the acromioclavicular joint, like dislocation or stretched or torn ligaments |

#include <openssl/conf.h>
typedef struct {
char *section;
char *name;
char *value;
} CONF_VALUE;
CONF *NCONF_new_ex(OSSL_LIB_CTX *libctx, CONF_METHOD *meth);

STACK_OF(CONF_VALUE) *NCONF_get_section(const CONF *conf, const char *name);
STACK_OF(OPENSSL_CSTRING) *NCONF_get_section_names(const CONF *conf);
NCONF_new_ex() creates a new CONF object in heap memory and assigns to it a context libctx that can be used during loading. If the method table meth is set to NULL then the default value of NCONF_default() is used.
NCONF_new() is similar to NCONF_new_ex() but sets the libctx to NULL.
NCONF_free() frees the data associated with conf and then frees the conf object.
NCONF_load() parses the file named filename and adds the values found to conf. If an error occurs file and eline list the file and line that the load failed on if they are not NULL.
NCONF_default() gets the default method table for processing a configuration file.
NCONF_get0_libctx() gets the library context associated with the conf parameter.
NCONF_get_section_names() gets the names of the sections associated with the conf as STACK_OF(OPENSSL_CSTRING) strings. The individual strings are associated with the conf and will be invalid after conf is freed. The returned stack must be freed with sk_OPENSSL_CSTRING_free().
NCONF_get_section() gets the config values associated with the conf from the config section name as STACK_OF(CONF_VALUE) structures. The returned stack is associated with the conf and will be invalid after conf is freed. It must not be freed by the caller.
NCONF_load() returns 1 on success or 0 on error.
NCONF_new_ex() and NCONF_new() return a newly created CONF object or NULL if an error occurs.
NCONF_new_ex(), NCONF_get0_libctx(), and NCONF_get_section_names() were added in OpenSSL 3.0.

‘Fun as Hell’: Kawhi Leonard and Paul George Share Court for the First Time
by Marcel MutoniThe LA Clippers’ stunning offseason haul materialized in full for the first time Wednesday night, with Paul George joining new teammate Kawhi Leonard on the court.
It was “fun as hell” for Clipper Nation as the superstar duo helped engineer a thrilling 107-104 win against the visiting Boston Celtics.
PG admits, however, that the team is still going through some “growing pains.”
Per The AP:
“It’s still tough,” said Leonard, who missed the previous three games with a sore knee. “We’re both on kind of minute restrictions so it’s hard to get a flow.”
George said he and Leonard are trying to get in sync with their other teammates.
“We’re going to have growing pains,” he said. “The great thing about myself and Kawhi is it doesn’t matter, we’re going to play basketball. Try to make the right plays and play off each other and just keep the game flowing. I thought in that aspect we were good.”
It was a wild and sloppy game for both teams. The Clippers committed 23 turnovers (Williams had seven while Leonard and George had five each) to 17 for the Celtics.
“That was an ugly win, but it was beautiful,” Clippers coach Doc Rivers said.

--- layout: post title: Understanding delete popular: popular tags: - js ---
A couple of weeks ago, I had a chance to glance through Stoyan Stefanov’s Object-Oriented Javascript. The book had an exceptionally high rating on Amazon (12 reviews with 5 stars), so I was curious to see if it was something worth recommending. I started reading through chapter on functions, and really enjoyed the way things were explained there; the flow of examples was structured in such nice, progressive way, it seemed even beginners would grasp it easily. However, almost immediately I stumbled upon an interesting misconception present throughout the entire chapter — deleting functions. There were some other mistakes (such as the difference between function declarations and function expressions), but we aren't going to talk about them now.
The book claims that “function is treated as a normal variable—it can be copied to a different variable and even deleted.”. Following that explanation, there is this example:
>>> var sum = function(a, b) {return a + b;}
>>> var add = sum;
>>> delete sum
true
>>> typeof sum;
"undefined"
Ignoring a couple of missing semicolons, can you see what’s wrong with this snippet? The problem, of course, is that deleting sum
variable should not be successful; delete
statement should not evaluate to true
and typeof sum
should not result in “undefined”. All because it’s not possible to delete variables in Javascript. At least not when declared in such way.
So what’s going on in this example? Is it a typo? A diversion? Probably not. This whole snippet is actually a real output from the Firebug console, which Stoyan must have been using for quick testing. It’s almost as if Firebug follows some other rules of deletion. It is Firebug that has led Stoyan astray! So what is really going on here?
To answer this question, we need to understand how delete
operator works in Javascript: what exactly can and cannot be deleted and why. Today I’ll try to explain this in details. We’ll take a look at Firebug’s “weird” behavior and realize that it’s not all that weird; we’ll delve into what’s going on behind the scenes when declaring variables, functions, assigning properties and deleting them; we'll look at browsers' compliance and some of the most notorious bugs; we’ll also talk about strict mode of 5th edition of ECMAScript, and how it changes delete
operator behavior.
I'll be using Javascript and ECMAScript interchangeable to really mean ECMAScript (unless explicitly talking about Mozilla's JavaScript™ implementation).
Unsurprisingly, explanations of delete
on the web are rather scarce. MDC article is probably the most comprehensive resource, but unfortunately misses few interesting details about the subject; Curiously, one of these forgotten things is the cause of Firebug’s tricky behavior. MSDN reference is practically useless.
So why is it that we can delete object properties:
var o = { x: 1 };
delete o.x; // true
o.x; // undefined
but not variables, declared like this:
var x = 1;
delete x; // false
x; // 1
or functions, declared like this:
function x(){}
delete x; // false
typeof x; // "function"
Note that delete
only returns false
when a property can not be deleted.
To understand this, we need to first grasp such concepts as variable instantiation and property attributes — something that’s unfortunately rarely covered in books on Javascript. I’ll try go over these very concisely in the next few paragraphs. It’s not hard to understand them at all! If you don’t care about why things work the way they work, feel free to skip this chapter.
There are 3 types of executable code in ECMAScript: Global code, Function code and Eval code. These types are somewhat self-descriptive, but here’s a short overview:
<p onclick="...">
) is usually parsed and treated as a Function code.eval
function is parsed as Eval code. We will soon see why this type is special.When ECMAScript code executes, it always happens within certain execution context. Execution context is a somewhat abstract entity, which helps understand how scope and variable instantiation works. For each of three types of executable code, there’s an execution context. When a function is executed, it is said that control enters execution context for Function code; when Global code executes, control enters execution context for Global code, and so on.
As you can see, execution contexts can logically form a stack. First there might be Global code with its own execution context; that code might call a function, with its own execution context; that function could call another function, and so on and so forth. Even if function is calling itself recursively, a new execution context is being entered with every invocation.
Every execution context has a so-called Variable Object associated with it. Similarly to execution context, Variable object is an abstract entity, a mechanism to describe variable instantiation. Now, the interesing part is that variables and functions declared in a source text are actually added as properties of this Variable object.
When control enters execution context for Global code, a Global object is used as a Variable object. This is precisely why variables or functions declared globally become properties of a Global object:
/* remember that `this` refers to global object when in global scope */
var GLOBAL_OBJECT = this;
var foo = 1;
GLOBAL_OBJECT.foo; // 1
foo === GLOBAL_OBJECT.foo; // true
function bar(){}
typeof GLOBAL_OBJECT.bar; // "function"
GLOBAL_OBJECT.bar === bar; // true
Ok, so global variables become properties of Global object, but what happens with local variables — those declared in Function code? The behavior is actually very similar: they become properties of Variable object. The only difference is that when in Function code, a Variable object is not a Global object, but a so-called Activation object. Activation object is created every time execution context for Function code is entered.
Not only do variables and functions declared within Function code become properties of Activation object; this also happens with each of function arguments (under names corresponding to formal parameters) and a special Arguments
object (under arguments
name). Note that Activation object is an internal mechanism and is never really accessible by program code.
(function(foo){
var bar = 2;
function baz(){}
/*
In abstract terms,
Special `arguments` object becomes a property of containing function's Activation object:
ACTIVATION_OBJECT.arguments; // Arguments object
...as well as argument `foo`:
ACTIVATION_OBJECT.foo; // 1
...as well as variable `bar`:
ACTIVATION_OBJECT.bar; // 2
...as well as function declared locally:
typeof ACTIVATION_OBJECT.baz; // "function"
*/
})(1);
Finally, variables declared within Eval code are created as properties of calling context’s Variable object. Eval code simply uses Variable object of the execution context that it’s being called within:
var GLOBAL_OBJECT = this;
/* `foo` is created as a property of calling context Variable object,
which in this case is a Global object */
eval('var foo = 1;');
GLOBAL_OBJECT.foo; // 1
(function(){
/* `bar` is created as a property of calling context Variable object,
which in this case is an Activation object of containing function */
eval('var bar = 1;');
/*
In abstract terms,
ACTIVATION_OBJECT.bar; // 1
*/
})();
We are almost there. Now that it’s clear what happens with variables (they become properties), the only remaining concept to understand is property attributes. Every property can have zero or more attributes from the following set — ReadOnly, DontEnum, DontDelete and Internal. You can think of them as flags — an attribute can either exist on a property or not. For the purposes of today’s discussion, we are only interested in DontDelete.
When declared variables and functions become properties of a Variable object — either Activation object (for Function code), or Global object (for Global code), these properties are created with DontDelete attribute. However, any explicit (or implicit) property assignment creates property without DontDelete attribute. And this is essentialy why we can delete some properties, but not others:
var GLOBAL_OBJECT = this;
/* `foo` is a property of a Global object.
It is created via variable declaration and so has DontDelete attribute.
This is why it can not be deleted. */
var foo = 1;
delete foo; // false
typeof foo; // "number"
/* `bar` is a property of a Global object.
It is created via function declaration and so has DontDelete attribute.
This is why it can not be deleted either. */
function bar(){}
delete bar; // false
typeof bar; // "function"
/* `baz` is also a property of a Global object.
However, it is created via property assignment and so has no DontDelete attribute.
This is why it can be deleted. */
GLOBAL_OBJECT.baz = 'blah';
delete GLOBAL_OBJECT.baz; // true
typeof GLOBAL_OBJECT.baz; // "undefined"
So this is what it’s all about: a special attribute on a property that controls whether this property can be deleted or not. Note that some of the properties of built-in objects are specified to have DontDelete, and so can not be deleted. Special arguments
variable (or, as we know now, a property of Activation object) has DontDelete. length
property of any function instance has DontDelete as well:
(function(){
/* can't delete `arguments`, since it has DontDelete */
delete arguments; // false
typeof arguments; // "object"
/* can't delete function's `length`; it also has DontDelete */
function f(){}
delete f.length; // false
typeof f.length; // "number"
})();
Properties corresponding to function arguments are created with DontDelete as well, and so can not be deleted either:
(function(foo, bar){
delete foo; // false
foo; // 1
delete bar; // false
bar; // 'blah'
})(1, 'blah');
As you might remember, undeclared assignment creates a property on a global object. That is unless that property is found somewhere in the scope chain before global object. And now that we know the difference between property assignment and variable declaration — latter one sets DontDelete, whereas former one doesn’t — it should be clear why undeclared assignment creates a deletable property:
var GLOBAL_OBJECT = this;
/* create global property via variable declaration; property has DontDelete */
var foo = 1;
/* create global property via undeclared assignment; property has no DontDelete */
bar = 2;
delete foo; // false
typeof foo; // "number"
delete bar; // true
typeof bar; // "undefined"
Note that it is during property creation that attributes are determined (i.e. none are set). Later assignments don't modify attributes of existing property. It's important to understand this distinction.
/* `foo` is created as a property with DontDelete */
function foo(){}
/* Later assignments do not modify attributes. DontDelete is still there! */
foo = 1;
delete foo; // false
typeof foo; // "number"
/* But assigning to a property that doesn't exist,
creates that property with empty attributes (and so without DontDelete) */
this.bar = 1;
delete bar; // true
typeof bar; // "undefined"
So what happens in Firebug? Why is it that variables declared in console can be deleted, contrary to what we have just learned? Well, as I said before, Eval code has a special behavior when it comes to variable declaration. Variables declared within Eval code are actually created as properties without DontDelete:
eval('var foo = 1;');
foo; // 1
delete foo; // true
typeof foo; // "undefined"
and, similarly, when called within Function code:
(function(){
eval('var foo = 1;');
foo; // 1
delete foo; // true
typeof foo; // "undefined"
})();
And this is the gist of Firebug’s abnormal behavior. All the text in console seems to be parsed and executed as Eval code, not as a Global or Function one. Obviously, any declared variables end up as properties without DontDelete, and so can be easily deleted. Be aware of these differences between regular Global code and Firebug console.
This interesting eval
behavior, coupled with another aspect of ECMAScript can technically allow us to delete non-deletable properties. The thing about function declarations is that they can overwrite same-named variables in the same execution context:
function x(){ }
var x;
typeof x; // "function"
Note how function declaration takes precedence and overwrites same-named variable (or, in other words, same property of Variable object). This is because function declarations are instantiated after variable declarations, and are allowed to overwrite them. Not only does function declaration replaces previous value of a property, it also replaces that property attributes. If we declare function via eval
, that function should also replace that property’s attributes with its own. And since variables declared from within eval
create properties without DontDelete, instantiating this new function should essentially remove existing DontDelete attribute from the property in question, making that property deletable (and of course changing its value to reference newly created function).
var x = 1;
/* Can't delete, `x` has DontDelete */
delete x; // false
typeof x; // "number"
eval('function x(){}');
/* `x` property now references function, and should have no DontDelete */
typeof x; // "function"
delete x; // should be `true`
typeof x; // should be "undefined"
Unfortunately, this kind of spoofing doesn’t work in any implementation I tried. I might be missing something here, or this behavior might simply be too obscure for implementors to pay attention to.
Knowing how things work in theory is useful, but practical implications are paramount. Do browsers follow standards when it comes to variable/property creation/deletion? For the most part, yes.
I wrote a simple test suite to check compliance of delete
operator with Global code, Function code and Eval code. Test suite checks both — return value of delete
operator, and whether properties are deleted (or not) as they are supposed to. delete
return value is not as important as its actual results. It’s not very crucial if delete
returns true
instead of false
, but it’s important that properties with DontDelete are not deleted and vice versa.
Modern browsers are generally pretty compliant. Besides this eval
peculiarity I mentioned earlier, the following browsers pass test suite fully: Opera 7.54+, Firefox 1.0+, Safari 3.1.2+, Chrome 4+.
Safari 2.x and 3.0.4 have problems with deleting function arguments; those properties seem to be created without DontDelete, so it is possible to delete them. Safari 2.x has even more problems — deleting non-reference (e.g. delete 1
) throws error; function declarations create deletable properties (but, strangely, not variable declarations); variable declarations in eval
become non-deletable (but not function declarations).
Similar to Safari, Konqueror (3.5, but not 4.3) throws error when deleting non-reference (e.g. delete 1
) and erroneously makes function arguments deletable.
Gecko 1.8.x browsers — Firefox 2.x, Camino 1.x, Seamonkey 1.x, etc. — exhibit an interesting bug where explicitly assigning to a property can remove its DontDelete attribite, even if that property was created via variable or function declaration:
function foo(){}
delete foo; // false (as expected)
typeof foo; // "function" (as expected)
/* now assign to a property explicitly */
this.foo = 1; // erroneously clears DontDelete attribute
delete foo; // true
typeof foo; // "undefined"
/* note that this doesn't happen when assigning property implicitly */
function bar(){}
bar = 1;
delete bar; // false
typeof bar; // "number" (although assignment replaced property)
Surprisingly, Internet Explorer 5.5 - 8 passes test suite fully except that deleting non-reference (e.g. delete 1
) throws error (just like in older Safari). But there are actually more serious bugs in IE, that are not immediately apparent. These bugs are related to Global object.
The entire chapter just for bugs in Internet Explorer? How unexpected!
In IE (at least, 6-8), the following expression throws error (when evaluated in Global code):
this.x = 1;
delete x; // TypeError: Object doesn't support this action
and this one as well, but different exception, just to make things interesting:
var x = 1;
delete this.x; // TypeError: Cannot delete 'this.x'
It’s as if variable declarations in Global code do not create properties on Global object in IE. Creating property via assignment (this.x = 1
) and then deleting it via delete x
throws error. Creating property via declaration (var x = 1
) and then deleting it via delete this.x
throws another error.
But that’s not all. Creating property via explicit assignment actually always throws error on deletion. Not only is there an error, but created property appears to have DontDelete set on it, which of course it shouldn’t have:
this.x = 1;
delete this.x; // TypeError: Object doesn't support this action
typeof x; // "number" (still exists, wasn't deleted as it should have been!)
delete x; // TypeError: Object doesn't support this action
typeof x; // "number" (wasn't deleted again)
Now, contrary to what one would think, undeclared assignments (those that should create a property on global object) do create deletable properties in IE:
x = 1;
delete x; // true
typeof x; // "undefined"
But if you try to delete such property by referecing it via this
in Global code (delete this.x
), a familiar error pops up:
x = 1;
delete this.x; // TypeError: Cannot delete 'this.x'
If we were to generalize this behavior, it would appear that delete this.x
from within Global code never succeeds. When property in question is created via explicit assignment (this.x = 1
), delete
throws one error; when property is created via undeclared assignment (x = 1
) or via declaration (var x = 1
), delete
throws another error.
delete x
, on the other hand, only throws error when property in question is created via explicit assignment — this.x = 1
. If a property is created via declaration (var x = 1
), deletion simply never occurs and delete
correctly returns false
. If a property is created via undeclared assignment (x = 1
), deletion works as expected.
I was pondering about this issue back in September, and Garrett Smith suggested that in IE "The global variable object is implemented as a JScript object, and the global object is implemented by the host. Garrett used Eric Lippert's blog entry as a reference.
We can somewhat confirm this theory by performing few tests. Note how this
and window
seem to reference same object (if we can believe ===
operator), but Variable object (the one on which function is declared) is different from whatever this
references.
/* in Global code */
function getBase(){ return this; }
getBase() === this.getBase(); // false
this.getBase() === this.getBase(); // true
window.getBase() === this.getBase(); // true
window.getBase() === getBase(); // false
The beauty of understanding why things work the way they work can not be underestimated. I've seen few misconceptions on the web related to misunderstanding of delete
operator. For example, there's this answer on Stackoverflow (with surprisingly high rating), confidently explaining how "delete is supposed to be no-op when target isn't an object property". Now that we understand the core of delete
behavior, it becomes pretty clear that this answer is rather inaccurate. delete
doesn't differentiate between variables and properties (in fact, for delete
, those are all References) and really only cares about DontDelete attribute (and property existence).
It's also interesting to see how misconceptions bounce off of each other, where in the very same thread someone first suggests to just delete variable (which won't work unless it's declared from within eval
), and another person provides a wrong correction how it's possible to delete variables in Global code but not in Function one.
Be careful with Javascript explanations on the web, and ideally, always seek to understand the core of the issue ;)
An algorithm for delete
is specified roughtly like this:
true
true
(where, as we now know, object can be Activation object or Global object)false
true
However, behavior of delete
operator with host objects can be rather unpredictable. And there's actually nothing wrong with that: host objects are allowed (by specification) to implement any kind of behavior for operations such as read (internal [[Get]] method), write (internal [[Put]] method) or delete (internal [[Delete]] method), among few others. This allowance for custom [[Delete]] behavior is what makes host objects so chaotic.
We've already seen some IE oddities, where deleting certain objects (which are apparently implemented as host objects) throws errors. Some versions of Firefox throw when trying to delete window.location
. You can't trust return values of delete either, when it comes to host objects; take a look at what happens in Firefox:
/* "alert" is a direct property of `window` (if we were to believe `hasOwnProperty`) */
window.hasOwnProperty('alert'); // true
delete window.alert; // true
typeof window.alert; // "function"
Deleting window.alert
returns true
, even though there's nothing about this property that should lead to such result. It resolves to a reference (so can't return true
on the first step). It's a direct property of a window
object (so can't return true
on a second step). The only way delete
could return true
is after reaching step 4 and actually deleting a property. Yet, property is never deleted.
The moral of the story is to never trust host objects.
As a bonus, here's another case of quirky delete behavior in IE:
var element = document.createElement('div')
delete element.onclick; // throws "Object doesn't support this action"
document.body.x = 1;
delete document.body.x; // throws "Object doesn't support this action"
// in IE8
delete XMLHttpRequest.prototype.open; // throws "Object doesn't support this action"
So what does strict mode of ECMAScript 5th edition bring to the table? Few restrictions are being introduced. SyntaxError is now thrown when expression in delete
operator is a direct reference to a variable, function argument or function identifier. In addition, if property has internal [[Configurable]] == false, a TypeError is thrown:
(function(foo){
"use strict"; // enable strict mode within this function
var bar;
function baz(){}
delete foo; // SyntaxError (when deleting argument)
delete bar; // SyntaxError (when deleting variable)
delete baz; // SyntaxError (when deleting variable created with function declaration)
/* `length` of function instances has { [[Configurable]] : false } */
delete (function(){}).length; // TypeError
})();
In addition, deleting undeclared variable (or in other words, unresolved Referece) throws SyntaxError as well:
"use strict";
delete i_dont_exist; // SyntaxError
This is somewhat similar to the way undeclared assignment in strict mode behaves (except that ReferenceError is thrown instead of a SyntaxError):
"use strict";
i_dont_exist = 1; // ReferenceError
As you now understand, all these restrictions somewhat make sense, given how much confusion deleting variables, function declarations and arguments causes. Instead of silently ignoring deletion, strict mode takes more agressive and descriptive measures.
This post turned out to be quite lengthy, so I'm not going to talk about things like removing array items with delete
and what the implications of it are. You can always refer to MDC article for that particular explanation (or read specs and experiment yourself).
Here's a short summary of how deletion works in Javascript:
If you'd like to get more familiar with things described here, please refer to ECMA-262 3rd edition specification.

This experience describes an initial experience of four people; two of which had also been on prescribed antidepressants.
10 mg doses were prepared for oral ingestion. Within several minutes (T+ 10-20m) the two not on medication came up with considerable underlying nausea, managable but pronounced.
Aat T+40m a female (120 lbs) rose very quickly, experiencing extreme sensory 'fuzz,' auditory and visual disturbance, and nausea. She eventually found herself unable to talk until T+ 90-115m. During the experience she was unable to communicate or move, other than through the use of her eyes.  Her primary experience of the trip lasted under 3 hours. The second individual, a male of about 130lbs, experienced a quick rise, enjoyable tactile and sensory waves and varying periods of mental clarity. His complete experience was enjoyable, with strong visual and auditory disturbance. He also smoked salvia at T=4hrs with great effect.
The third person experienced GREAT difficulty. She took the same 10mg oral dose, but was also on Wellbutrin (prescribed). At T+ 40 she experienced very strong auditory disturbance, i.e. the pitch of music was terribly exagerated, and she had a sensitivity to volume. MOST IMPORTANTLY, she began to experience excruciating chest pains. The feeling was described as having the heart squeezed, without an ability to gain breath. The pain was both consistent and persistent. Her difficulty lasted about 4 hours (until T+ 5hr). At times, her pulse dropped to about 52 b/m, she had occasional muscle 'spasms/convulsions'(she said because the pain was so unbearable), and was weak. We kept her awake and attentive, gave her cola--in case it was gas--and asked her if she would receive medical attention, to which she vehemently resisted. At T+ 3.5hr her pulse reached 82b/m but pain took longer to subside. There was no pain following the experience.
The fourth person, a male of about 130lbs, was also on lexapro, (escitalopram, an SSRI) (30mgs). None of the effects were experienced as strongly as any of the other people. As luck would have it, this person's muted trip was helpful in responding to #3's bad reaction. We also called two sober individuals to monitor the situation in case #3 became worse.
In summary, what we thought was a relatively low dose based on readings and research, did not turn out to be so. Three of the individual had strong reactions, one with frightening pain. Subsequent research revealed that a rare side effect of Wellbutrin is irregular heart beat and other heart and breathing issues. Also, looking into other methoxy susbtances revealed common complications with the heart and respiratory system. Please approach Wellbutrin and 5-MeO-DIPT with caution.

This lesson contains the following sections
If you electronically send someone an important document (or documents), or an applet or application to run, the recipient needs a way to verify that the document or code came from you and was not modified in transit (for example, by a malicious user intercepting it). Digital signatures, certificates, and keystores all help ensure the security of the files you send.
keytool
or security API methods.
That is, you generate a digital signature for the document or code, using
the jarsigner
tool or Security API methods.
A recipient needs to ensure that your public key itself is authentic before he/she can use it to verify that your signature is authentic. Therefore, you will usually supply a certificate that contains your public key together with the key of a Certificate Authority who can vouch for your key's authenticity. See the next section for details.
For more information about the terminology and concepts of signing and verification, and further explanation of the benefits, see the Signing JAR Files section of the "The Packaging Programs in JAR Files" lesson.
If the recipient cannot establish a trust chain, then he/she can calculate the
the certificate fingerprint(s),
using the keytool
-import
or -printcert
command.
A fingerprint is a relatively short number that uniquely and
reliably identifies the certificate. (Technically, the fingerprint is a hash
value of the certificate information, using a message digest function.)
The recipient can then phone the
certificate owner and compare the fingerprint values of the
received certificate with the certificate that was sent.
If the fingerprints are the same, the certificates are the
same.
Thus you can ensure that a certificate was not modified in transit. One other potential uncertainty when working with certificates is the identity of the sender. Sometimes a certificate is self-signed, that is, signed using the private key corresponding to the public key in the certificate; the issuer is the same as the subject. It is reasonable to self-sign a certificate if the recipient already trusts the sender.
Otherwise the sender needs to obtain a certificate from a trusted third party, referred to as a certification authority (CA). To do so, you send a self-signed certificate signing request (CSR) to the CA. The CA verifies the signature on the CSR and your identity, perhaps by checking your driver's license or other information. The CA then vouches for your being the owner of the public key by issuing a certificate and signing it with its own (the CA's) private key. Anybody who trusts the issuing CA's public key can now verify the signature on the certificate. In many cases the issuing CA itself may have a certificate from a CA higher up in the CA hierarchy, leading to certificate chains.
Certificates of entities you trust are typically imported into your keystore as "trusted certificates." The public key in each such certificate may then be used to verify signatures generated using the corresponding private key. Such verifications can be accomplished by:
jarsigner
tool (if the document/code and signature
appear in a JAR file),
If you are sending signed code or documents to others, you need to
supply them with the certificate containing the public key corresponding
to the private key used to sign the code/document.
The keytool
-export
command or API methods
can export your certificate from your keystore to a file, which can then be
sent to anyone needing it. A person who receives the certificate can import
it into the keystore as a trusted certificate, using,
for example, API methods or the
keytool
-import
command.
If you use the jarsigner
tool to generate a signature for a JAR file,
the tool retrieves your certificate and its supporting certificate chain from
your keystore. The tool then stores them, along with the signature, in the JAR
file.
Private keys and their associated public key certificates are stored in password-protected databases called keystores. A keystore can contain two types of entries: the trusted certificate entries discussed above, and key/certificate entries, each containing a private key and the corresponding public key certificate. Each entry in a keystore is identified by an alias.
A keystore owner can have multiple keys in the keystore,
accessed via different aliases.
An alias is typically named after a particular role in which the
keystore owner uses the associated key. An alias may
also identify the purpose of the key. For example, the alias
signPersonalEmail
might be used to identify a keystore entry whose
private key is used for signing
personal e-mail, and the alias signJarFiles
might be used to identify an
entry whose private key is used for
signing JAR files.
The keytool
tool can be used
to
API methods can also be used to access and to modify a keystore.
jar
tool.
A JAR file is a good way of encapsulating multiple files in one spot.
When a file is "signed", the resulting digital signature bytes need to be stored
somewhere. When a JAR file is signed, the signature can go in the JAR file
itself. This is what happens when you use the jarsigner
tool to sign a JAR file.
jarsigner

a JAR file signature,
the person/organization that received the JAR file first needs to
import into their keystore a certificate authenticating the
public key corresponding to the private key used to sign the code.

corresponding to the private key used to sign that document using keytool
.
Then it shows how your recipient can verify your signature by installing your public key certificate and then using the jarsigner
tool to verify your
signature.
These two lessons have much in common. In both cases, the first two steps for the code or document sender are to:
jar
tool.
keytool
-genkey
command.
keytool
-certreq
command;
then send the resulting certificate signing request
to a certification authority (CA) such as VeriSign.
keytool
-import
command
to import the CA's response.
jarsigner
tool and the private key generated earlier.
keytool
-export
command.
Then supply the signed JAR file and the
certificate to the receiver.
keytool
-import
command.
The keytool
will attempt to construct a trust chain from the
certificate to be imported to an already trusted certificate in the
keystore. If that fails, the keytool
will display the certificate fingerprint
and prompt you to verify it.
If what was sent was code, the receiver also needs to modify a policy file to permit the required resource accesses to code signed by the private key corresponding to the public key in the imported certificate. The Policy Tool can be used to do this.
If what was sent was one or more documents, the receiver needs to
verify the authenticity of the JAR file signature,
using the jarsigner
tool.
This lesson discusses the two optional steps. The other steps are covered in the next two lessons, Signing Code and Granting It Permissions and Exchanging Files .
When keytool
is used to generate public/private key pairs,
it creates a keystore entry containing a private key and a self-signed
certificate for the public key.
(That is, the certificate is signed using the corresponding private key.)
This may be adequate if the people receiving your
signed files already know and trust your identity.
However, a certificate is more likely to be trusted by others if it is signed by a certification authority (CA). To get a certificate signed by a CA, you first generate a certificate signing request (CSR), via a command such as the following:
keytool -certreq -alias alias -file csrFile
You then submit this file to a CA, such as VeriSign, Inc. The CA authenticates you, the requestor ("subject"), and then signs and returns a certificate authenticating your public key. By signing the certificate, the CA vouches that you are the owner of the public key.
In some cases, the CA will return a chain of certificates, each one authenticating the public key of the signer of the previous certificate in the chain.
If you submitted a certificate signing request (CSR) to a certification authority (CA), you need to replace the original self-signed certificate in your keystore with a certificate chain by importing the certificate (or chain of certificates) returned to you by the CA.
But first you need a "trusted certificate" entry in your keystore
(or in the cacerts
keystore file, described below)
that authenticates the CA's public key. With such an entry the CA's
signature can be verified. That is, the CA's signature
on the certificate, or on the final certificate in the
chain the CA sends to you in response to your
CSR, can be verified.
Before you import the certificate reply from a CA, you need
one or more "trusted certificates" in your keystore or in the
cacerts
file.
The cacerts
file represents a system-wide keystore with CA certificates.
This file resides in the JRE security properties directory,
java.home/lib/security
, where java.home is
the JRE installation directory.
cacerts
File
cacerts
file as entities for signing and issuing certificates to
other entities, you must manage the cacerts
file carefully.
The cacerts
file should contain only certificates of the
CAs you trust. It is your responsibility to
verify the trusted root CA certificates bundled
in the cacerts
file and make your own trust
decisions. To remove an untrusted CA certificate
from the cacerts
file, use the delete option of
the keytool
command.
You can find the cacerts
file in the JRE
installation directory. Contact your system administrator
if you do not have permission to edit this file.
cacerts
file contains a number of trusted CA
certificates. If you sent your CSR to one of these trusted
vendors (such as VeriSign),
you won't need to import the vendor's root
certificate as a trusted certificate in your keystore; you can
go on to the next section to
see how to import the
certificate reply from the CA.
A certificate from a CA is usually either
self-signed or signed by another CA, in which case you also need a
certificate authenticating that CA's public key. Suppose that company
ABC, Inc., is a CA and that you obtain a
file named ABCCA.cer
, purportedly a
self-signed certificate from
ABC, authenticating that CA's public key.
Be very careful to ensure that the certificate is
valid prior to importing it as a "trusted" certificate!
View it first (using the keytool
-printcert
command or the
keytool
-import
command
without the -noprompt
option),
and make sure that the displayed certificate fingerprint(s) match the
expected ones. You can call the person who sent the certificate
and compare the fingerprint(s) that you see with the ones that they show
or that a secure public key repository shows.
Only if the fingerprints are equal is it guaranteed that the certificate has not been
replaced in transit with somebody else's (for example, an attacker's) certificate.
If such an attack took place and you did not check the certificate
before you imported it, you would end up trusting anything the
attacker has signed.
If you trust that the certificate is valid, you can add it to your keystore via a command such as the following:
keytool -import -alias alias -file ABCCA.cer -keystore storefile
ABCCA.cer
,
and it is assigned the specified alias.
Once you've imported the required trusted certificate(s), as described
in the previous section, or they are
already in your keystore or in the cacerts
file,
you can import the certificate reply and thereby
replace your self-signed certificate with a certificate
chain. This chain will be either the one returned by the CA in response to
your request (if the CA reply is a chain) or one constructed (if the
CA reply is a single certificate) by using
the certificate reply and trusted certificates that are already available
in the keystore or in the
cacerts
keystore file.
As an example, suppose that you sent your certificate signing request to VeriSign. You can then import the reply via the following, which assumes that the returned certificate is in the file specified by certReplyFile:
keytool -import -trustcacerts -keystore storefile -alias alias -file certReplyFile
Type this command on one line.
The certificate reply is validated by
using trusted certificates from the keystore and optionally by using the
certificates configured in the cacerts
keystore file (if the
-trustcacerts
option is specified).
Each certificate in the chain is verified, using the
certificate at the next level higher in the chain. You need to
trust only the top-level "root" CA certificate in the chain. If you do not
already trust the top-level certificate, keytool
will display the fingerprint
of that certificate and ask you whether you want to trust it.
The new certificate chain of the specified (by alias) entry replaces the old certificate (or chain) associated with this entry. The old chain can be replaced only if a valid keypass, the password used to protect the private key of the entry, is supplied. If no password is provided and if the private key password is different from the keystore password, the user is prompted for it.
