After many years of web development, I finally decided to change my way. Security has always been a dream so the goal is now to perform as a pentester.
Luckily, nowadays there is tons of documentation, pdf, videos, blog, course about offensive security on Internet. Reading, learning, training became my daily. The goal of this site is not to teach anything to anyone but it’s a very good reminder for me. Plus it’s good way to test more deeply the tools used by professional pentesters and hackers.
In october 2015, after 3 months of hard work, I successfully passed the famous Offensive Security Certified Professional exam aka OSCP. Now as a real training, I work on bug bounty programs on HackerOne.
If you want to get in touch, feel free to contact me :)

Preheat the oven to 200C/390F/Gas 6.
Lay the chicken on a chopping board, skin-side down. Remove the two mini-fillets of chicken breast and set aside.
Lay the slices of proscuitto over the chicken breast and stuff into the legs.
In a small bowl, mix the mascarpone with the rosemary and lemon zest and juice.
Place a spoonful of the mascarpone mixture onto both breasts and into the legs, reserving one spoonful.
Flatten the mini-fillets slightly using a rolling pin and place back on top of the mascarpone-covered breasts. Roll the chicken over, tucking the legs back under and the skin around to neaten.
Heat an ovenproof frying pan and add half of the olive oil. Season the chicken with salt and freshly ground black pepper, and place skin-side down in the frying pan. Fry for two minutes, or until the skin is golden-brown.
Place in the oven and roast for 18-25 minutes, until cooked through - test the chicken is cooked by piercing the meat with a skewer; if the juices run clear, the chicken is cooked.
 Place the chicken onto a plate and rest, covered with aluminium foil, for five minutes.
Add the final spoonful of the mascarpone mixture to the pan and whisk into the meaty juices.
Meanwhile, bring a pan of salted water to the boil. Add the purple sprouting broccoli and Romanesco broccoli and cook for three minutes, or until just tender.
Drain the broccoli and place back into the pan. Toss with the remaining olive oil and season with salt and freshly ground black pepper.
To serve, carve the chicken in half and serve with the broccoli.


Provider Operation¶
A feature which allow the developers to override the DB Provider specific operations (i.e: BulkInsert).
How is it being used?
Some operations of the Repositories or extended methods of the DbConnection object is using a DB Provider specific functionality. Bulk-insert is one of the operation that is widely used for SQL Server, Oracle, MySql (and any other DB Provider that supports Bulk-Insert), but it is not commonly used in OLE DB providers. By overriding, the default implementation of the library, a developer can write and customize its own way of implementing this.
Why BulkInsert is a DB Provider specific feature?
Considering ADO.NET, by default, it has included the SqlBulkCopy class that allow developers to implement bulk-operation for SQL Server databases. The library is also using the SqlBulkCopy class to support the SQL Server bulk-insert operation.
For other provider to get supported, a specialized <Provider>BulkCopy class must be implemented that uses the proper way of doing the bulk-operations.
DbOperationProviderMapper¶
This class is used to map the Type of database provider into an instance of IDbOperationProvider object.
By default, the SqlDbOperationProvider class is provided by the library which is mainly used for SQL Server DB providers.
A code below is called in the static constructor of this class.
static DbOperationProviderMapper()
{
// Default for SqlConnection
Add(typeof(SqlConnection), new SqlDbOperationProvider());
}
Notice, this class itself has defaulted the SqlConnection mappings into SqlDbOperationProvider object.
A code below is a simple call to map a customized IDbOperationProvider class named OracleDbOperationProvider into an Oracle DB provider.
DbOperationProviderMapper.Add(typeof(OracleConnection), new OracleDbOperationProvider(), true);
The last boolean argument is used to override an existing mapping (if present). Otherwise, an exception will be thrown.
IDbOperationProvider¶
An interface used to mark the class to become a database operation provider. Below is a sample code that implements this interface.
public class OracleDbOperationProvider : IDbOperationProvider
{
public int BulkInsert<TEntity>(IDbConnection connection,
IEnumerable<TEntity> entities,
IEnumerable<BulkInsertMapItem> mappings = null,
OracleBulkCopyOptions options = OracleBulkCopyOptions.Default,
int? bulkCopyTimeout = null,
int? batchSize = null,
IDbTransaction transaction = null)
where TEntity : class
{
...
}
public int BulkInsert<TEntity>(IDbConnection connection,
DbDataReader reader,
IEnumerable<BulkInsertMapItem> mappings = null,
OracleBulkCopyOptions options = OracleBulkCopyOptions.Default,
int? bulkCopyTimeout = null,
int? batchSize = null,
IDbTransaction transaction = null)
where TEntity : class
{
...
}
public int BulkInsert(IDbConnection connection,
string tableName,
DbDataReader reader,
IEnumerable<BulkInsertMapItem> mappings = null,
OracleBulkCopyOptions options = OracleBulkCopyOptions.Default,
int? bulkCopyTimeout = null,
int? batchSize = null,
IDbTransaction transaction = null)
{
...
}
}
Once the class OracleDbOperationProvider has been mapped to Oracle DB Provider, then the library will automatically use it in Oracle bulk-insert operations.
SqlDbOperationProvider¶
This class is used by the Repositories and other extended methods of the DbConnection object to execute a DB Provider specific operations. As of today, the current identified provider specific operation is the BulkInsert operation. By default, the library has mapped this class into a SqlConnection DB provider.
Below is the implementation of this class.
public class SqlDbOperationProvider : IDbOperationProvider
{
// Sync
public int BulkInsert<TEntity>(IDbConnection connection,
DbDataReader reader,
IEnumerable<BulkInsertMapItem> mappings = null,
SqlBulkCopyOptions options = SqlBulkCopyOptions.Default,
int? bulkCopyTimeout = null,
int? batchSize = null,
IDbTransaction transaction = null)
where TEntity : class
{
...
}
// Async
public Task<int> BulkInsertAsync<TEntity>(IDbConnection connection,
DbDataReader reader,
IEnumerable<BulkInsertMapItem> mappings = null,
SqlBulkCopyOptions options = SqlBulkCopyOptions.Default,
int? bulkCopyTimeout = null,
int? batchSize = null,
IDbTransaction transaction = null)
where TEntity : class
{
...
}
}

This dessert defines an exact moment in the season – the end of autumn and the beginning of winter – and I prepare it as soon as the first quince are ripe. However, with its warm and spicy flavours it is also a lovely prelude to Christmas.
Each serving provides 226kcal, 9g protein, 26g carbohydrate (of which 18.5g sugars), 0.5g fat (of which 0.1g saturates), 5g fibre and 0g salt.
For the red wine jus, in a saucepan over a high heat, bring the red wine to the boil for 2 minutes, which will remove much of the alcohol, then add 400ml/14fl oz water and the remaining jus ingredients and bring to a gentle simmer.
For the winter fruit, poach the quince in the simmering jus for around 25 minutes. Add the apples and pears and simmer for 4 minutes. Leave to cool to room temperature before adding the prunes and blackberries (if using). Strain a third of the liquor and freeze overnight; cover and chill the remaining liquid and fruit in the fridge.
To serve, scrape the frozen cooking liquor with a fork to create beautiful flakes of perfumed ice. Arrange the fruit, spices and cooking juices in a large dish or divide between four bowls. At the last moment, put a spoonful of the delicate flakes of spiced wine granita on top of your dessert. You could alternatively serve the granita in small cups from the freezer as a little pre-dessert.

Hi to all,
I want use the sct-013-020 (20A) with my emontx (obviously after removing the resistor on the PCB) someone already tested it?
I would like to know if someone has the sct-013-020 datasheet with indication about turns ratio etc in order to calculate all the needed correction.
I didn't find that infos in the global sct-013 datasheet
thanks in advance
Re: ct : sct-013-020 datasheet and turn ratios
Best insight into the SCT-013-XXX is here -
http://openenergymonitor.org/emon/buildingblocks/report-yhdc-sct-013-000-current-transformer
I belive the turns ratio is 2000:1 and I think the only other difference through the range is the presence/value of a burden resistor or protection diodes.
Re: ct : sct-013-020 datasheet and turn ratios
I believe richmc is correct, but it's unproven. The value of the internal burden resistor (where fitted, i.e. all except the -000) appears to be selected on test to give the rated output.
I also have a suspicion that different models come from different factories or sub-contractors, since the cable screen is sometimes connected and sometimes not.
Re: ct : sct-013-020 datasheet and turn ratios
as stated, it is unconfirmed, but if the number of turns for the 100 amp and the 30amp are the same, then the only real difference is the addition of the internal burden resistor and the diodes.
assuming that is the case, then we would expect that an Arduino would see a full scale, 100 amp reading at it's 5 volts on the ADC pin.
that would also mean that a 30 amp reading would only be 30% of that ?
based on the simple fact that if you are only ever going to see a 20 amp load, then the ADC of the arduino will be completely un-effect and there is no 'loss' of accuracy and no 'un-used' range of the ADC. it is just that a 20 amp load will only ever rise to a certain voltage.
my question is then if we can do anything to get a more accurate reading in the 0-20a range.
a suggestion is to add a zero-dropout-circuit. so that currents less than 0.1, the software just reads 0. more peace of mind than anything else.
Re: ct : sct-013-020 datasheet and turn ratios
A little context to your post would be helpful - this thread is over 2½ years old!
We believe all the SCT-013-xxx range are the same device. The only difference is the value of the internal burden resistor, all except for the -000 that is, which has 8 V (from memory) protection diodes instead of an internal burden, and requires you to provide an external burden. Therefore, if you require a 0 - 20 A input range, your best choice is to use the -000 variant and calculate your external burden resistor value to give you a peak-peak voltage across the burden that is few percent less (*) than the maximum input voltage range on a 20 A primary current.
* to allow for component tolerances - 5% should be enough, but if you anticipate a 'peaky' current wave, you should allow a lot more unless you can calculate or measure the crest factor and use that when calculating the peak-peak value.
Re: ct : sct-013-020 datasheet and turn ratios
It wou be nice if the burden resistance could be controlled in software, even if it's just two or three ranges. The software could sample at the lowest range, and step up to the next range if needed.
Or, if redesigning the board, use a dedicated IC like the Cirrus Logic CS5463, which should in theory have better resolution.
Re: ct : sct-013-020 datasheet and turn ratios
I know this has been an old thread, but interest is still high. I wish that someone would confirm with the factory as to the turns and also the machines they use so as to get an accurate count. the machines that to that these days are so simple they should be dead on.
I have photos of my -030 that is open.
uploaded 2 pics in case that helps.
mine has 2 resistors. a 000 and a 62
it also has diodes 7.5 each
The bare wires from the transformer hover over the board, protected by varnish, but look like they could cause problems for some.
Re: ct : sct-013-020 datasheet and turn ratios
Normally, the turns ratio is adjusted in manufacture according to the properties of the core etc so that the errors over the working current range are minimised. Therefore, nobody can "confirm with the factory as to the turns" because it is the factory's prerogative to change it in order to meet the published specification - and just in case you didn't know, current transformers are specified by the current ratio in actual units, and not by the turns ratio. That should of course be obvious from my first sentence.
Therefore, the SCT-013-000 is a 100:50 mA transformer, not a 2000:1 (which would mean it would handle a 2 kA primary current and give 1 A of secondary current flowing in the burden).
In terms of the "voltage output" types, it is normal for the manufacturer to adjust the value of the burden resistor in manufacture again so as to obtain the specified output over the required range. That's the reason for the multiple pads visible in your photo.

So I bought that dang Chromebook over three years ago at this point and it keeps chugging on. Google has continued to ship OS updates (which I only notice as weird, arbitrary UI changes) and I can still use it to code but its main purpose now is its new life: ChromeOS runs Android apps pretty well, so I put an SD card full of movies on it and play them via VLC for my kid.
All in all, the Chromebook was a good purchase, it has served many purposes, and it’s lasted a lot longer than a lot of other laptops I’ve owned (Surface Pro, looking at you).
I’ve got a Pinebook Pro on the way, here’s hoping that lasts as long (and is as useful).


Erica Mena And Jordyn Woods Worked Together On BET’s Thriller, ‘Sacrifice’ – See The Trailer!
by Alexis StoneJordyn Woods made her fans happy when she revealed that she was featured in her very first movie with a leading role. Now, it turns out that Erica Mena also worked on the same project, and both ladies posted about it on their social media accounts.
You may recall that back in August, BET Networks revealed the production of a new original movie called ‘SACRIFICE’ starring Paula Patton.
The action takes place in LA following Daniella Hernandez, played by Patton, who is a highly sought after entertainment lawyer. You can check out more in the trailer below.
Here’s Jordyn’s caption:
‘#Sacrifice starring @PaulaPattonOfficial and @theericaash Streaming on December 19th Exclusively on @betplus If you don’t already have your subscription, now is a good time to get it!!! @footagefilmsstudios written directed and created by @chrisstokes1969 produced by @cityofrome @simplysmooth1 also starring @jordynwoods @aceb47 @iamerica_mena @marqueshouston @juanantonio @vbozeman @bethertv @betplus @bet.’
People continued to congratulate Jordyn on her massive achievement.
Someone told her: ‘U needed 2 step first 2 get a clear view before u step up. Now it’s all the way to the top.🔥🔥🔥🔥 look arts you girl and look at God doing what He promised to do. Intervention to the next level.’
Another follower said: ‘I’M SO PROUD OF YOU. Yes, I’m yelling because I mean it❤❤❤❤WIN after WIN ( insert Win Again by Nicki Minaj)’
One fan wrote: ‘I will be getting BET Plus this me hooked in just the seconds I saw!!!! I saw you Jordyn on plaque then in the hospital!!!! Yes, Sis kill it, Multi-talented never talentless.’
Erica shared the same trailer on her social media account, and she also got praised by her fans.
All the ladies and everyone involved in the production received tons of congratulations.

When we were establishing the properties of the standard normal density, we discovered that if $X$ and $Y$ are independent standard normal then $X^2 + Y^2$ has the exponential $(1/2)$ distribution. We saw this by comparing two settings in which the Rayleigh distribution arises. But that isn't a particularly illuminating reason for why $X^2 + Y^2$ should be exponential.
In this section we will study the distribution of $Z^2$ where $Z$ is standard normal. We will follow that in the next section by getting a better understanding of $X^2 + Y^2$ where $X$ and $Y$ are i.i.d. standard normal, and then study an extension to a method of inference.
Let $Z$ be standard normal. To find the density of $V = Z^2$, we can start by finding the cdf of $V$. For $v > 0$,
$$ P(V \le v) ~ = ~ P(Z^2 \le v) ~ = ~ P(-\sqrt{v} \le Z \le \sqrt{v}) ~ = ~ \Phi(\sqrt{v}) - \Phi(-\sqrt{v}) $$Differentiate with respect to $v$ and use the symmetry of the standard normal density $\phi$ to see that the density of $V$ is given by
$$ f_V(v) ~ = ~ \frac{\phi(\sqrt{v})}{\sqrt{v}}, ~~~~ v > 0 $$Thus if $Z$ is standard normal and $V = Z^2$, the density of $V$ is
$$ f_V(v) ~ = ~ \frac{1}{\sqrt{2\pi}} v^{-\frac{1}{2}} e^{-\frac{1}{2} v}, ~~~~ v > 0 $$In exercises you showed that the gamma $(r, \lambda)$ density is given by
$$ f(t) ~ = ~ \frac{\lambda^r}{\Gamma(r)} t^{r-1}e^{-\lambda t}, ~~~~ t > 0 $$where $$ \Gamma(r) ~ = ~ \int_0^\infty t^{r-1}e^{-t}dt $$
is the gamma the gamma function of mathematics and satisfies $\Gamma(r+1) = r\Gamma(r)$.
Now notice the form of the density of $V$, the square of a standard normal variable. It's the gamma density with parameters $r = 1/2$ and $s = 1/2$. By equating constants, you can see that $\Gamma(1/2) = \sqrt{\pi}$.
Squares of standard normal variables are important in statistical inference, as you will soon see. The random variable $V$ which is the square of one standard normal variable is said to have the chi-squared distribution with 1 degree of freedom. This rather bizarre terminology is equivalent to "the gamma (1/2, 1/2) distribution." The terminology will become more comprehensible in the next section.
v = np.arange(0, 3, 0.01)
y = stats.chi2.pdf(v, 1) # The second argument is the degrees of freedom.
plt.plot(v, y, color='darkblue', lw=2)
plt.xlabel('$v$')
plt.ylabel('$f_V(v)$', rotation=0)
plt.title('Chi-squared (1) Density');
For a positive integer $n$, the random variable $X$ has the chi-squared distribution with $n$ degrees of freedom if the distribution of $X$ is gamma $(n/2, 1/2)$. That is, $X$ has density
$$ f_X(x) ~ = ~ \frac{\frac{1}{2}^{\frac{n}{2}}}{\Gamma(\frac{n}{2})} x^{\frac{n}{2} - 1} e^{-\frac{1}{2}x}, ~~~~ x > 0 $$Here are the graphs of the chi-squared densities for degrees of freedom 2 through 5.
Take a look at the graph of the chi-squared density wih 2 degrees of freedom. If you think it looks like the exponential $(1/2)$ density, you are right. We'll see why in the next section. For now, let's check that the mean and variance works out correctly.
You showed in exercises that if $T$ has the gamma $(r, \lambda)$ density then
$$ E(T) ~ = ~ \frac{r}{\lambda} ~~~~~~~~~~~~ SD(T) = \frac{\sqrt{r}}{\lambda} $$If $X$ has the chi-squared $(n)$ distribution then $X$ is gamma $(n/2, 1/2)$. So
$$ E(X) ~ = ~ \frac{n/2}{1/2} ~ = ~ n $$Thus the expectation of a chi-squared random variable is its degrees of freedom.
The SD is $$ SD(X) ~ = ~ \frac{\sqrt{n/2}}{1/2} ~ = ~ \sqrt{2n} $$
We have guessed that the chi-squared $(2)$ distribution is the same as exponential $(1/2)$. By the formulas above and those we already know for the exponential, the expectations and SDs of the two distributions agree, and all four values are equal to 2.
The next section explains how the all chi-squared distributions are related to each other and to the standard normal distribution.


Working with individual genomic regions¶
Contents
Genomic intervals, or regions, as we call them from here on, are represented
by a api/regions/GenomicRegion
object. This object has attributes
commonly associated with genomic regions, such as “chromosome”, “start” and “end”,
but can in principle have arbitrary attributes, including scores, labels, and other
useful properties describing the region. There is no restriction regarding the types
of attributes - any valid Python object can be associated with a
GenomicRegion
.
This tutorial assumes you have imported the genomic_regions package like this:
import genomic_regions as gr
Creating genomic regions¶
You can create a genomic region by calling the GenomicRegion
constructor:
region = gr.GenomicRegion(chromosome='chr1', start=1, end=1000)
# or to simplify
region = gr.GenomicRegion('chr1', 1, 1000)
start
and end
must be of type int.
The strand
attribute also has special restrictions. It can either be a str
("+"
, "-"
, "."
), an int (-1
, +1
) or None
.
region = gr.GenomicRegion('chr1', 1, 1000, strand='+')
Other attributes have no restrictions, but we recommend that score
be a float,
to show the expected behavior when working with the region later on.
region = gr.GenomicRegion('chr1', 1, 1000, strand='+',
score=1.765, name="my region",
my_list=[1, 2, 3, 4])
You can also add attributes to the region later on by using the set_attribute
method:
region = gr.GenomicRegion('chr1', 1, 1000, strand='+')
region.set_attribute("my_dict", {'a': 1, 'b': 2})
We advise the use of set_attribute
rather than the builtin setattr
region.my_dict = {'a': 1, 'b': 2}
, as some processing is done to the
key, value pair by GenomicRegion
for compatibility.
Finally, you can quickly create GenomicRegion
objects from strings using the
as_region
convenience function:
region = gr.as_region('chr1:1-1000:+')
The region string should have the format <chromosome>:<start>-<end>[:<strand>]
.
start
and end
can use common abbreviations for kilo- and megabases,
support decimal and thousand separators, and are case-insensitive,
so writing gr.as_region('chr12:12500000-18000000')
is the same as
gr.as_region('chr12:12.5Mb-18Mb')
and gr.as_region('chr12:12.5mb-18mb')
and
gr.as_region('chr12:12,500,000-18,000,000')
.
Genomic region methods¶
Basic¶
The GenomicRegion
object comes loaded with useful attributes and methods,
most of which are self-explanatory:
len(region) # returns the size of the region in base pairs
region.center # returns the base (or fraction of base) at the center of the region
region.five_prime # returns the starting base at the 5' end of the region
region.three_prime # returns the starting base at the 3' end of the region
region.is_forward() # True if strand is '+' or '+1'
region.is_reverse() # True if strand is '-' or '-1'
region.attributes # return all attribute names in this region object
region.copy() # return a shallow copy of this region
region.to_string() # return a region identifier string describing the region
The strand
attribute returns an integer (or None
, if no strand is set).
To obtain a string, use the method strand_string
, which returns one of
+
, -
, or .
.
Modifying the region¶
Some methods are provided that modify the underlying region.
region.expand
changes the size of the region on the chromosome, either by an
absolute amount in base pairs (using any of the parameters absolute
,
absolute_left
, or absolute_right
), or relative, as a fraction of the
current region size (relative
, relative_left
, or relative_right
).
By default, these actions return a modified copy of the original region, but you can
modify the region in place using copy=True
.
region = gr.as_region('chr12:12.5Mb-18Mb')
print(region) # chr12:12500000-18000000
new_region = region.expand(absolute='1mb')
print(new_region) # chr12:11500000-19000000
print(region) # chr12:12500000-18000000
region.expand(relative=1.5, copy=False)
print(region) # chr12:4250000-26250000
You can also easily move a region on the same chromosome by adding or subtracting base pairs.
region = gr.as_region('chr12:12.5Mb-18Mb')
new_region = region + 1000000
print(new_region) # chr12:13500000-19000000
Some databases store chromosome names with the ‘chr’ prefix, others without. You can use
the method fix_chromosome
to switch between chromosome formats:
region = gr.as_region('chr12:12.5Mb-18Mb')
new_region = region.fix_chromosome()
print(new_region) # 12:12500000-18000000
Relationship to other regions¶
You can easily check if a region overlaps with another region:
region = gr.as_region('chr12:12.5Mb-18Mb')
region.overlaps('chr12:11Mb-13Mb') # True
region.overlaps('chr12:11Mb-11.5Mb') # False
region.overlaps('chr1:11Mb-13Mb') # False
Similarly, you can get the extent of the overlap in base pairs:
region = gr.as_region('chr12:12.5Mb-18Mb')
region.overlap('chr12:11Mb-13Mb') # 500000
region.overlap('chr12:11Mb-11.5Mb') # 0
Next steps¶
Next, we will see how to work with lists and collections of regions in Working with collections of genomic regions.

On June 20, the XFire and Celtix communties submitted a proposal to the Apache Software Foundation for a new project called CeltiXfire. CeltiXfire is a proposed merge of the XFire and Celtix communities and code. On July 22, the proposal was accepted. We, the XFire team, are very excited about this. As we started to think about XFire 2.0 there are a lot of things we want to do. Things like full support for JAX-WS and support for other web service specifications, like WS-RM. We'd also like to improve on a lot of features that we already have, like our JMS support. Both the Celtix code and team are strong in many of these areas. After talking to them, it was clear that both project's goals lined up quite nicely. Additionally both projects were looking to start on their next version, so the timing was just right to start working together. After much discussion, we decided a merge would benefit both projects and their communities. As an XFire user, we understand that you may be concerned about the merge. It is helpful to think of the merge like XFire 2.0. While the APIs will change a bit as we improve on them, the same ideas and features will in the merged code. The major difference between doing 2.0 on our own and merging is that there will be more developers, more support, and more features than the XFire community could do on its own. We also want you to know that XFire 1.x will be supported long into the future. For instance, we have a new feature release coming out soon - 1.2 - which adds support for things like Aegis inheritance, GZIP, and JMS topics. And most importantly, we will continue to make bug fix release as often and as long as needed. We are still waiting for our proposal to be officially accepted, and once we do we will have Apache mailing lists set up for discussion and questions. In the mean time if you have questions or concerns, please email the XFire mailing lists. FAQWhat are the goals of the merge?Some of the goals we have highlighted are:
What are the non goals of the merge?
What is Celtix?Celtix is a web service framework with support for legacy integration. It primarily focuses on providing JAX-WS and WS-* support. This makes it an ideal candidate for merging with XFire as those are two areas where XFire is weak. It also has support for CORBA services via Apache (incubating) Yoko. Is Celtix an ESB?While Celtix has traditionally called itself an ESB, if you look at the code you'll see that Celtix has primarily focused on providing JAX-WS and WS-* support. The new project will NOT be branded as an ESB. It will be primarily focused on service creation and infrastructure. In other words a lot of web services and some support for legacy (i.e. non-XML) integration. Whats going to happen to XFire 1.x and applications which use it?XFire 1.x will be supported long into the future. For instance, we have a new feature release coming out soon - 1.2 - which adds support for things like Aegis inheritance, GZIP, and JMS topics. And most importantly, we will continue to make bug fix release as often and as long as needed. We are currently planning to add a compatability layer for XFire 1.x users in CeltiXfire. Most importantly, the Aegis binding and the Handler interface should both be able to be supported in the new version. Other APIs will chance (as in any 2.0), but there wil be a straightforward migration path. What will the merge look like?After spending some time looking at both Celtix and XFire it was clear that neither one was 100% suitable to just start merging in code from the other project. After some delibiration, we've decided to write a small core and merge bits from each project on top of that. The analagous portion of code in XFire would be the XFire Core module. The idea is to take XFire's architectual ideas - Handlers, the service model, ServiceFactorys, etc - and tweak them to meet a larger set of requirements. One thing we're looking to do is create cleaner separation of bindings and transports. In XFire the two run together. We want to support more bindings than just SOAP - like REST or Plain Ol' XML and this is a necessary step in doing so. Other important departures will be a better databinding API and better support for WS-ReliableMessaging semantics. On top of this new core we are looking to merge in modules from each project. These include (but are not limited to):
The other major change for XFire users is that the API will be Java 5 based. For users wishing to run on Java 1.4, retrotranslator is available as a solution. Note that we've outlined this plan before the merge officially starts. Once the Apache mailing lists are set up there will be a chance for discussion and voting on particular issues that people feel are controversial. What is the timeline?While we are not ready to announce an official timeline, it is clear that many people will be working on the merge from both XFire and Celtix. Once we solidify the core APIs, releases should proceed very quickly. Who works on Celtix?Celtix is funded by IONA Technologies. The project has around 15 committers, with many of them working full time on the project. How do I get involved in the merge?We will have Apache mailing lists set up soon. We would love for you to join in in the new project once they are set up! Check this space in the future for more information. I'm concerned about X! Where can I get further information?We are currently waiting for the Apache mailing lists to be set up. In the mean time if you have questions, please email the XFire mailing lists. |

This was my first time using ecstasy.
previous drug use: codeine, cannabis(often), dxm(often), drinking pretty heavily(not often, its pretty bad for your brain), salvia.
preparations: I had been meditating for a week or so, training my mind to focus on what i wanted it to focus on. as a result of this preparation, i felt no paranoia about whether the experience would turn sour, and no worries about whether this pill i was going to be taken was adulterated. While meditating i had been focusing on my third eye, and working towards opening it. i had succesfully felt and seen my third eye open two days before my experience, but only for a few seconds. I also prepared buy drinking two liters of water before hand, eating saltine crackers with hummus, taking two multivitamins, and purchasing an extra package of crackers and an extra liter of water for my journey. i also brought my ipod to heighten the senses, and my cell phone in case things went sour. i also didnt take anything illegal with me, so that if i saw a cop, i wouldnt have any worries.
Mindset: I was somewhat nervous at first, as i always get when first trying a substance. thanks to the meditation, i was easily able to calm my mind down, and open it to any possibilities of what may occur during my experience. I had also been feeling somewhat emotionally empty for the past couple months, and was feeling as if i was losing my true personality, because i am normally a very emotional person, not in the sense of being dramatic or oversensitive, but in the sense of being able to develop deep, true love very easily, and having alot of natural empathy for everyone, and lately i had been feeling different.
setting: I planned to spend my glorious first time in the local state park, by myself. the park is near the ocean so its filled with dunes and trees. it was sunny, with some cool looking clouds, and a vague sense of change in the air.
the experience: I took the pill at 4:30. it was a blueish green playboy pill. I instantly felt more happy. it was probably placebo. I told my mom i was going for a bike ride to the state park. i thought the bike ride would get my blood flowing and help me feel the ecstasy more. about twenty minutes after taking the pill, my stomach felt like it was being covered in menthol, and it felt wonderful, as if i could feel the mdma leaving my stomach and entering my bloodstream. i knew that it was starting.
I was on the way to the dunes in the park, and i noticed a wedding going on at the boardwalk. i showed up exactly at the part of the ceremony where the bride and groom kiss. i couldnt stop smiling, and i felt amazingly lovey-dovey seeing these two join there souls together.
i went to the seven eleven to pick up some water and crackers. this is at about the 40 min. mark. at this point i feel much more energetic and empathic, and i find myself with little to no inhibitions at this point. i can tell the people at the counter think that im high, and i just dont even care. im actually glad that im high enough to be recognized as high. I flash everyone in the store i see a big smile, and the room just feels lighter and happier when i leave.
I bike past a hotel, and i hear someone saying 'hey kid, hey kid.' so I turn around and ask the man from where the sounds seems to be coming what he wants. he looks at me with a confused look on his face and says in the same voice that i heard, 'i didnt say anything, man.' auditory hallucination? maybe... I experienced a few as the day went along.
I reach the park, and the motions of the trees are very exaggerated. my euphoria is very present now, and the grin is pasted on my face for the next couple hours. this is about 1 hour in.
I arrive at the dune, and it feels like im floating. walking feels effortless. i sit at a tree stump and drink some water.i feel confident that this is the right place for the experience. the mdma felt for the most part how i had expected it to feel. not much body buzz, but a little bit, and a strong, ever-present feeling of confidence, free-spiritedness, and euphoria.
i bring out the ipod. its time. I put on that song by cascada thats kinda popular, and the voice is incredible. i close my eyes, and it feels like ive floated above the clouds, and am now inside the singers head, just floating around. the music was so crystal clear, i could hear every nuance of change in tone, i could sense when the producers had used pitch correction, i could feel the breath producing the pitch touching my ears. it felt like the music was pouring into my skull and bouncing around inside. needless to say, this heightened my happiness by alot, and at this point, i was ready to understand why ecstasy is tied to the rave scene.
the drums started pounding that beat right as i started running. i ran down the dune and danced. i danced. and danced. i didnt feel my intensely high heart beat. i didnt feel out of breath, even though i was. i didnt feel the stitch in my side from all the water id been drinking. and i didnt worry about not feeling them either. it seemed something so trivial, so earthly, that it was of no importance. it felt like my purpose at that moment was to squeeze every bit of happiness out of my head at once, and the only way i could do that was to keep moving. I cut my feet on the broken glass in the sand (its a big party spot for kids), and didnt even stop to worry about it. i ran, through many dunes, through many parts of the forest, always returning to the main dune, always feeling like i was constantly coasting forward. hence the term 'rolling.'
i stopped for water often, just to keep my fear of dehydration away from my thoughts. The dancing was amazing, and definitely the height of the presence of the drug.
i could tell my heart was being pushed, so i stopped dancing for a while. this is at the two hour mark. i folded my legs indian style and started to meditate. i focused on my feelings, and tried to secure them in my memory in order to bring them back out at anytime in the future. meditation is great for that kind of stuff. its like you can control anything in your mind. anyway, i thought about how great it would be to take ecstasy with this girl im digging on, because of its great ability to open feelings, and make me honest with myself. I also felt that ecstasy could be a drug i take anytime, not habitually since it would lose its magic, but it seems like something that could cheer up any situation, any time, with any group of people. I thought about why i had felt so empty lately, and i was unable to come up with a conclusion. i believe its just a time where my emotions are resting, and not that i have lost my emotions.
I began to focus on my third eye. i curled up into a ball, sitting on the dune, and focused on the empty space for where my third eye is. small silhouettes began to take shape, and i noticed an eye shape, orange colored, beginning to take a stronger shape. i felt the space in between my two eyes stretch open, and i knew what was happening. i opened my eyes, and could see the circle of vision that my third eye was seeing. it was floating right in front of me, producing images of faces and monsters and landscapes and shapes. it was different then before.
i then realized it was time to head home, cause i was going to see Superbad that night. i put on Going to California by led zeppelin on my ipod as i was walking out of the forest, as it is my favorite song ever. i was singing all the lyrics, and the people who live near the entrance to the park, gave me a wierd look, but the feeling I get on ecstasy is so understanding, so honest, so innocent, so free, that I am not concerned with why they would be giving me wierd looks, and I'm not concerned with why I'm singing. i was singing because it felt right, and good, and that is that. i was singing because my heart told me to, and so few people ever listen to their heart.
i biked home. superbad was fucking hilarious. the happiness seemed permanent. i never crashed.
the end of my first of many ecstasy experiences to come.

In multi-party video calls, attendees can enable the simulcast feature to enhance the overall video quality. Simulcast is a standardized technique where the video publishers create multiple renditions, or layers, of the same video source and video subscribers have the flexibility to choose the rendition that best fits their needs based on such factors as available bandwidth, compute and screen size.
The uplink policy controls the configuration of the renditions through camera capture and encoding parameters. The simulcast-enabled uplink policy is SimulcastUplinkPolicy.
If you want more fine-grained control of which simulcast layer to subscribe, please use VideoPriorityBasedPolicy. More details about priority-based downlink policy can be
found here.
Simulcast support is built into the WebRTC library in the majority of browsers. The video input resolution is used to initially configure the attributes and maximum number of allowed simulcast streams. In WebRTC, if the RTCRtpSender is configured to have three layers of encoding, then the top layer is specified by the video input resolution. The resolution of the middle layer is scaled down by two vertically and horizontally by WebRTC. The lower layer is scaled down by four. The WebRTC library supports a maximum of three simulcast layers, and only when the input resolution is 960x540 or higher will all three be available.
The recommended resolution in JS SDK is 1280x720. This resolution will provide the most flexibility and allow subscribers to maintain smoother video quality transitions. In certain circumstances, like mobile browsers, the input resolution may not be high enough to support all desired simulcast streams, so the logic will adapt appropriately to send as many as possible.
The SimulcastUplinkPolicy configures RTCRtpSender to have three encoding layers, but only ever enables two of them. Which two are enabled is based on a variety of factors. Experiments show that configuring RTCRtpSender with three encoding layers up front and dynamically enabling and disabling layers provides a better experience and reduces the burden of having to dynamically manage capture resolution and encoding parameters.
WebRTC ultimately controls how much data is being sent to the network based on its bandwidth estimation algorithm. It's very hard to circumvent the estimated bandwidth or trick WebRTC into sending more than it estimates. Most browsers expose WebRTC peer connection statistics which developers can access to retrieve the estimated available bandwidths for uplink or downlink.
The estimated available bandwidth reveals some information of the health of the E2E network and can trigger various WebRTC behaviors when facing network adversity or in recovering from a network glitch. SimulcastUplinkPolicy does its best to anticipate and react to the underlying WebRTC behavior and work with it to avoid further impact on the video quality of services.
The SimulcastUplinkPolicy implements the following logic:
Publishers/Attendees
Estimated Uplink Bandwidth
Simulcast stream 1
Simulcast stream 2
Attendees <= 2
Any
1280x720@15fps 1200 kbps

320x180@15fps 200 kbps
Publishers <= 6 and
> 300 kbps
640x360@15fps 600 kbps
320x180@15fps 150 kbps
Publishers > 6 and
>= 350 kbps
640x360@15fps 350 kbps
320x180@15fps 200 kbps
Publishers > 6 and
>= 300 kbps
640x360@15fps 350 kbps
320x180@15fps 150 kbps
Any number publishers
< 300 kbps
Not used
320x180@15fps 300 kbps
The table entries represent the maximum configuration. When CPU and bandwidth consumption is overused, WebRTC will dynamically adjust bitrate, disable a layer or scale down resolution. The SimulcastUplinkPolicy has a monitoring mechanism which tracks the sending status and automatically adjusts without need for application intervention.
Note that simulcast is disabled when there are only 2 or fewer attendees. This is because WebRTC has additional functionality to request lower bitrates from the remote end, and we will forward these requests if there are no competing receivers (i.e. if the receiving estimates it has 200kbps downlink bandwidth available, this will be sent and relayed in a message to the sending client). Therefore there is no need for simulcast based adaption.
The VideoAdaptiveProbePolicy adds functionality to take advantage of video simulcast. The goal of this policy is to leave the complexity of managing the downlink bandwidth and decision of which streams to request inside the SDK and remove that burden from the application. The policy monitors numerous pieces of information and uses that to determine which streams to subscribe to. The data considered are:
Message from infrastructure enumerating video streams from each remote client
Estimated downlink bandwidth from WebRTC library
Media metrics such as packet loss and used bandwidth
Stream type - Screen share or camera device
The policy works by listening to any changes in the information listed above. Anytime there is a change it re-evaluates the best mix of remote videos to fit within the target downlink bandwidth. The policy is currently configured to try to request as many remote clients as possible, then increase resolution where possible. It prioritizes screen share video above people video. If there is insufficient bandwidth to request all far participants then only a certain number will be seen.
If the application pauses a remote video by calling pauseVideoTile, then this policy will not include that remote video in the list of available streams and therefore will not automatically subscribe or unsubscribe from it while it is in the paused state.
When using the policy it is recommended that applications do not take action on the downlink monitoring metrics from metricsDidReceive since it may conflict with decisions being made within the policy.
import {ConsoleLogger,DefaultDeviceController,DefaultMeetingSession,LogLevel,MeetingSessionConfiguration} from'amazon-chime-sdk-js';constlogger = newConsoleLogger('MyLogger', LogLevel.INFO);constdeviceController = newDefaultDeviceController(logger);// You need responses from server-side Chime API. See 'Getting responses from your server application' in the README.constmeetingResponse = // The response from the CreateMeeting API action.constattendeeResponse = // The response from the CreateAttendee or BatchCreateAttendee API action.// This meeting session configuration will be used to enable simulcast in the next step.constconfiguration = newMeetingSessionConfiguration(meetingResponse, attendeeResponse);
Now enable enableSimulcastForUnifiedPlanChromiumBasedBrowsers feature flag
in the created MeetingSessionConfiguration.
configuration.enableSimulcastForUnifiedPlanChromiumBasedBrowsers = true;//Specify the apdative probe downlink policyconfiguration.videoDownlinkBandwidthPolicy = newVideoAdaptiveProbePolicy(logger);
Now create a meeting session with the simulcast enabled meeting session configuration.
// In the examples below, you will use this meetingSession object.constmeetingSession = newDefaultMeetingSession(configuration,logger,deviceController);
This meetingSession is now simulcast enabled and will have the videoUplinkBandwidthPolicy set to DefaultSimulcastUplinkPolicy and videoDownlinkBandwidthPolicy set to VideoAdaptiveProbePolicy. Due to these policies, the local and remote video resolutions may change. The video resolution depends on the available simulcast streams. The available simlucast streams are dependent on the number of attendees and the current bandwidth estimations. Check "Simulcast resolutions and behavior" section in this guide for more information.
The active simulcast streams are represented by the SimulcastLayers enum. Currently, the active upstream simulcast layers will only be either "Low and High", or "Low and Medium" or "Low". To receive upstream simulcast layer change notification do the following steps:
Then, add an instance of the AudioVideoObserver using the addObserver method so you can receive the changed simulcast layer notification.
Now when you are in a simulcast enabled meeting and your upstream simulcast layer is changed, you will be notified in the encodingSimulcastLayersDidChange callback with the updated simulcast layer.
import { SimulcastLayers } from'amazon-chime-sdk-js';constSimulcastLayersMapping = {[SimulcastLayers.Low]:'Low',[SimulcastLayers.LowAndMedium]:'Low and Medium',[SimulcastLayers.LowAndHigh]:'Low and High',[SimulcastLayers.Medium]:'Medium',[SimulcastLayers.MediumAndHigh]:'Medium and High',[SimulcastLayers.High]:'High'};constobserver = {encodingSimulcastLayersDidChange:simulcastLayers=> {console.log(`current active simulcast layers changed to: ${SimulcastLayersMapping[simulcastLayers]}`); }}meetingSession.audioVideo.addObserver(observer);
You can use enableSimulcastForContentShare to toggle simulcast on/off for content share. Note that you don't have
to set enableSimulcastForUnifiedPlanChromiumBasedBrowsers yourself as this configuration will be set automatically
for content share attendee as part of enableSimulcastForContentShare.
Below is the default simulcast encoding parameters:
Encoding Parameters
Simulcast stream 1
Simulcast stream 2
Max bitrate
1200 kbps
300 kbps
Scale resolution down by
1
2
Max framerate
Same as capture framerate (default is 15fps)
5
You can override the encoding parameters to tailor to the type of content.
For example, for motion content, you may want to scale resolution down more but keep a high framerate for the low
quality layer but for static content, you may want to only reduce the framerate and keep a high resolution.
// Enable simulcast and override the low layer encoding parametersawaitmeetingSession.audioVideo.enableSimulcastForContentShare(true, {low: {maxBitrateKbps:350,scaleResolutionDownBy:4,maxFramerate:10, }});awaitmeetingSession.audioVideo.startContentShareFromScreenCapture();
Video Simulcast
In multi-party video calls, attendees can enable the simulcast feature to enhance the overall video quality. Simulcast is a standardized technique where the video publishers create multiple renditions, or layers, of the same video source and video subscribers have the flexibility to choose the rendition that best fits their needs based on such factors as available bandwidth, compute and screen size. The uplink policy controls the configuration of the renditions through camera capture and encoding parameters. The simulcast-enabled uplink policy is SimulcastUplinkPolicy.
Simulcast is currently disabled by default. To enable it MeetingSessionConfiguration.enableSimulcastForUnifiedPlanChromiumBasedBrowsers must be set. Currently, only Chrome 76 and above is supported.
The VideoAdaptiveProbePolicy downlink policy adaptively subscribes to the best simulcast layer and is automatically selected if [MeetingSessionConfiguration.enableSimulcastForUnifiedPlanChromiumBasedBrowsers is set to true.
If you want more fine-grained control of which simulcast layer to subscribe, please use VideoPriorityBasedPolicy. More details about priority-based downlink policy can be found here.

Simulcast resolutions and behavior
WebRTC ultimately controls how much data is being sent to the network based on its bandwidth estimation algorithm. It's very hard to circumvent the estimated bandwidth or trick WebRTC into sending more than it estimates. Most browsers expose WebRTC peer connection statistics which developers can access to retrieve the estimated available bandwidths for uplink or downlink.

Therefore there is no need for simulcast based adaption.
Downlink Bandwidth Policy
The VideoAdaptiveProbePolicy adds functionality to take advantage of video simulcast. The goal of this policy is to leave the complexity of managing the downlink bandwidth and decision of which streams to request inside the SDK and remove that burden from the application. The policy monitors numerous pieces of information and uses that to determine which streams to subscribe to. The data considered are:
The policy works by listening to any changes in the information listed above. Anytime there is a change it re-evaluates the best mix of remote videos to fit within the target downlink bandwidth. The policy is currently configured to try to request as many remote clients as possible, then increase resolution where possible. It prioritizes screen share video above people video. If there is insufficient bandwidth to request all far participants then only a certain number will be seen.
Applications will receive notifications of remote video being added or removed through the videoTileDidUpdate and videoTileWasRemoved callbacks. You can use encodingSimulcastLayersDidChange to know when the selected upstream simulcast resolutions change.
If the application pauses a remote video by calling pauseVideoTile, then this policy will not include that remote video in the list of available streams and therefore will not automatically subscribe or unsubscribe from it while it is in the paused state.
When using the policy it is recommended that applications do not take action on the downlink monitoring metrics from metricsDidReceive since it may conflict with decisions being made within the policy.
The VideoAdaptiveProbePolicy can be used with or without simulcast. To enable it without simulcast set the MeetingSessionConfiguration.videoDownlinkBandwidthPolicy to VideoAdaptiveProbePolicy. If simulcast is not active, then the policy will only be able to add or remove remote videos.
Creating a simulcast enabled meeting
First, create a meeting session configuration.
Now enable
enableSimulcastForUnifiedPlanChromiumBasedBrowsers
feature flag in the created MeetingSessionConfiguration.Now create a meeting session with the simulcast enabled meeting session configuration.
This
meetingSession
is now simulcast enabled and will have thevideoUplinkBandwidthPolicy
set to DefaultSimulcastUplinkPolicy andvideoDownlinkBandwidthPolicy
set to VideoAdaptiveProbePolicy. Due to these policies, the local and remote video resolutions may change. The video resolution depends on the available simulcast streams. The available simlucast streams are dependent on the number of attendees and the current bandwidth estimations. Check "Simulcast resolutions and behavior" section in this guide for more information.Receive upstream simulcast layer change notification
The active simulcast streams are represented by the SimulcastLayers enum. Currently, the active upstream simulcast layers will only be either "Low and High", or "Low and Medium" or "Low". To receive upstream simulcast layer change notification do the following steps:
Implement the encodingSimulcastLayersDidChange method from the AudioVideoObserver interface.
Then, add an instance of the
AudioVideoObserver
using the addObserver method so you can receive the changed simulcast layer notification.Now when you are in a simulcast enabled meeting and your upstream simulcast layer is changed, you will be notified in the
encodingSimulcastLayersDidChange
callback with the updated simulcast layer.Custom Simulcast Policy
If the default simulcast uplink policy does not work for you, you can create your own simulcast video uplink policy by implementing SimulcastUplinkPolicy and set the video uplink policy via MeetingSessionConfiguration.videoUplinkBandwidthPolicy.
Enable Simulcast For Content Share
You can use
enableSimulcastForContentShare
to toggle simulcast on/off for content share. Note that you don't have to setenableSimulcastForUnifiedPlanChromiumBasedBrowsers
yourself as this configuration will be set automatically for content share attendee as part ofenableSimulcastForContentShare
.Below is the default simulcast encoding parameters:
You can override the encoding parameters to tailor to the type of content. For example, for motion content, you may want to scale resolution down more but keep a high framerate for the low quality layer but for static content, you may want to only reduce the framerate and keep a high resolution.

CADILLAC MAN A film review by Robert Dorsett Copyright 1990 Robert Dorsett
CADILLAC MAN stars Robin Williams as Joey O'Brien, a car salesman in New York. The first third of the film documents his various personal problems: he's juggling relationships with four women, owes a mobster $20,000, and will lose his job the next day, unless he sells twelve new cars. He is eventually put in a situation in which he'll have to reverse his losing streak, or he'll lose his life.
The movie sounds trite, and it is, to a degree. It's essentially yet another platform for Williams to strut his stuff (and is vaguely reminiscent of GOOD MORNING, VIETNAM). The principal gag is that Joey can argue himself out of anything, but life is conspiring to make it all an up-hill battle. The production quality, however, raises it out of the gutter: it has a good supporting cast, and isn't *quite* as clear-cut as the advertisements make out.
There are a number of good gags, both subtle and overt. It won't have people rolling in the aisles, but it has its moments. I'd give it a 6/10, or three stars. It's a "feel-good," Christmassy sort of flick. It won't be the blockbuster of the summer, but then again, films released in mid-May rarely are.
