NEVER, AGAIN, FOREVER A film review by Steve Rhodes Copyright 1997 Steve Rhodes
RATING (0 TO ****): *
NEVER, AGAIN, FOREVER is a feature length documentary about the Jewish Defense League (JDL). I saw it as part of San Jose's Cinequest film festival. [The punctuation of the film's title is a bit strange, but that is what is printed in the official program.]
I love documentaries, and I am fairly flexible about their content and composition. I do however have certain minimal standards. I expect a documentary to be more than just a collection of film stock, and although I do not count on a big budget look, I do want a picture that it is clear and bright enough to be visible. NEVER, AGAIN, FOREVER fails both of these tests.
In any documentary, even mediocre ones like this one, there are some interesting moments. I did learn that at least some people in the JDL are obsessed with hate. One woman quotes the slain Meir Kahane as saying, "You have to hate first before you can love." Whether he actually said this or not, is open to question. In fact, the whole documentary is so one-sided that I began not to believe anything in it. It may all be true, but documentarians Danae Elon and Pierre Chainet, by sticking to a single theme and approach, caused their whole thesis to be laid open to question.
The technical aspects of the picture are abysmal. The film is sometimes out of focus, but more often there is not enough light to see the subject. Many interviews are done in a car with the bright lights of the background causing the iris of the lens to close down. This meant we had to watch a talking shadow. Only when another car would go by and block the sun would we get a glimpse of the subject. When you realize that you could have done a much better job with the camera than the camera operator, you know a picture is in trouble.
The director appears never to have storyboarded what he wanted to do with the film he had shot. The editing seems almost random.
I left the NEVER, AGAIN, FOREVER more confused than when I went in. Documentaries should enlighten and involve the audience. This one did neither.
NEVER, AGAIN, FOREVER runs 58 minutes. The film is not rated. Although the subject is potentially quite interesting, I do not find this documentary worth recommending. I give it a single *.
**** = A must see film. *** = Excellent show. Look for it. ** = Average movie. Kind of enjoyable. * = Poor show. Don't waste your money. 0 = Totally and painfully unbearable picture.

It was getting late in the evening in downtown apartment on a Monday night, when the phone rang. It was my fiends Jeremy who is the lead singer of a band. As usual, Jer was in search of some weed, and I was usually the guy who sold it to him. But, I had quit smoking weed for three months at this point, because I wanted to improve my OCD and bipolar disorder. Nevertheless, I ended up finding it for him anyway, and I could resist the temptation of smoking a cone. It was especially tempting because I wanted to see how my latest prescription, Imovane, would react when combined with cannabis use.
It was now a only little while after taking my nightly regimen, that was to include a combination of the following: 2000mg Divalproex, 250mg Fluvoxomine, 2mg Risperidone, 45mg Mirtazapine, and the more recent addition, 7-15mg Zopiclone. Tonight I had only taken one and a half of the 7.5 mg Imovane tablets.
After A while of sitting on the couch in my medicated daze, I began to obsess over the small amount of reefer that I had pinched out of the bag for myself. With in a matter of minutes I had rolled one up and was smoking it.
Eventually I ended up in my bed, talking on the phone with my ex-girlfriend for about an hour. She told me that I sounded all “doped up”, and she also asked me if I was okay. But I felt absolutely fine..
The suddenly, a wave of unbearable nausea came over my whole body, an my mind when into some kind of trance, sort of like the k-hole.   Afterwards, I went back to lay in me bed but this time brough a garbage can to throw up in, and I did. I puked up the most acidic mixure ever concocted.  This phase lasted about an hour and a half.
When the whole thing passed I still felt like a can of smashed ass-holes, and I couldn’t get to sleep. I decided to take another Zopiclone, and It was good night for me. I will never smoke weed again as long as I am on these medications. The consequences of doing so were not worth it. I blame it on the Depakote mainly, but who knows?

NOTE: This is just because a lot of beginners need a grasp on this concept.
WHAT IT IS
----------
Pointers are addresses. The can be assigned, or made to "point to" another memory location. They are a powerful concept that is not well understood by many users of C. Their use can make code more efficient, more readable, and more functional.
HOW TO USE IT
-------------
Pointers are declared by using the following template (assuming T is a type):
Of course, some prefer the convention of:
but these modifications are in the personal opinion of the user, since the compiler ignores the whitespaces in a declaration (that don't seperate a type and the first variable).
The address of a normal variable can be assigned to a pointer as follows:
1 2 3
|
T *ptr;
T var;
ptr=&var;
| |
This works because the ampersand (&) will take the address of var, and assign the value to the pointer, which itself holds an address.
Pointers to pointers can be made. And so can pointers to those, but they are hardly useful.
The asterisk (*) can dereference a pointer.
1 2 3 4 5 6
|
T *ptr;
T var, var2;
ptr=&var;
var2=*ptr;
*ptr+=var2;
| |
The last two statements effectively assign var2 the value of var (because the dereference operator tells the machine to follow the pointer to the variable), then adds var2 to var (the same as doubling var). Since the pointer was dereferenced to the same location as var, all operations on the dereferenced pointer will take effect on the variable it points to.
Often, to signify the state of not pointing to anything, a pointer will be assigned the value of 0. This pointer is the null pointer. It is illegal to dereference a null pointer.
Pointers can be declared constant by putting the keyword const before the asterisk in the declaration:
Do NOT confuse this with
which defines var to point to a type of constant T. Constant pointers must be initialized. Arrays, in fact, are constant pointers.
The space allocated for pointers is the space necessary to hold a memory address. This is usually an unsigned long.
Pointers can be redirected to multiple targets. For example:
1 2 3 4 5 6 7 8
|
T *ptr;
T var, var2;
ptr=&var;
//Do some stuff with var
ptr=&var2;
//Do some stuff with var2
| |
Pointers have their own kind of arithmetic: adding or subtracting values (let's say X) actually causes a shift in the address equal to X*sizeof(T). This is how arrays dereference (the expression a[x] is really *(a+x), which works because arrays are constant pointers). Multiplication and division are not allowed.
A pointer to any arbitrary type T must have the declaration T * OR one of the special types, void *. Void pointers (not to be confused with null pointers) can be assigned an address to any value. Because of this, pointer arithmetic on void pointers is illegal, as is dereferencing them. You can dereference and perform arithmetic on a casted void pointer, though.
A pointer definition doesn't implicitly span to each member in a declaration, you need an asterisk before each pointer variable.
WHY YOU NEED THEM
-----------------
ARRAYS, ARRAYS, ARRAYS!!! Every array is a constant pointer, so it is pretty crucial to have this feature.
Functions normally are passed copies of their parameters. By passing addresses (and defining the function to receive a pointer), the caller's value can be modified. Passing of this type is called pass by reference.
Pointers are crucial to the processing of strings. Every C String is a character array, and hence a constant pointer to a character.
They are also necessary when making linked lists and using dynamic memory allocation. Using pointers for dynamic memory allocation means you can:
-use the same pointer for multiple seperate memory spaces.
-assign this value to any other pointer with the same type or a void *.
-Define an arbitrarily long range to be put under a single pointer. This is the basis of arrays.
GOING FARTHER
-------------
Go ahead, try a few pointings. Remember, you have to cast a void pointer to use it.
Pointers are used internally on several occasions. Not a program doesn't have a pointer in it, because functions are pointers to the compiled code for that function in their data segment (yes, even main). Find other such uses.
Your reply is valued! Please give questions and comments below!

BladeEnc DLL
version 1.0
(BladeEnc engine version 0.75 and 0.82)
Programmers Manual
BladeEnc.DLL and this manual is copyright Tord Jansson and may be
distributed freely
as long as no modifications are made to neither one of them.
The BladeEnc engine is heavily based on distribution 10 of ISO's
reference
source code for MPEG Layer 3 encoding.
The DLL-Interface for the BladeEnc engine was written by
Jukka Poikolainen
Homepage: http://bladeenc.cjb.net
E-mail<EMAIL_ADDRESS>Distribution
People and companies who wants to distribute BladeEnc.DLL with their commercial products are free to do so as far as I'm concerned, but should be aware that BladeEnc.DLL might infringe certain MP3 related software patents held by Fraunhofer IIS in certain countries.
However, these patents are not valid in countries that doesn't approve
of software patents, which includes Sweden and, as far as I know,
most other European Countries as well. Don't ask me for specific information
about any other countries, I don't have that information.
Disclaimer
BladeEnc.DLL and this manual is distributed 'as is' with no warranty
of any kind. The Author is not to be held responsible for the result of
any use or misuse of this product.
Current Bugs and Limitations
Although the interface is designed to be able to handle multiple parallel
streams it can't be done yet due to limitations in the engine, only one
stream is allowed.
Future Compatibility
This interface should be compatible with all future versions of BladeEnc.DLL
without any need to recompile your programs. You should therefore not
check the version number upon start and prevent users from running your
program with a later version of BladeEnc.DLL.
How to use the DLL
1. Fill in a PBE_CONFIG structure and send it to beInitStream(). Make sure that BE_ERR_SUCCESSFUL is returned.
2. Reserve at least the amount of memory returned in dwBufferSize as your output buffer.
3. Call beEncodeChunk() until you've encoded everything you want.
4. Call beDeinitStream() to make sure that all encoded data is flushed out before closing the stream.
5. Close the stream using beCloseStream().
Return Values
See the header-file for a complete list of function return values. All
functions should return BE_ERR_SUCCESSFUL unless something went wrong.
The BE_CONFIG - structure
These are the members of the BE_CONFIG structure you need to fill in
before you call beInitStream():
| dwConfig | Specifies what kind of output you want. Since only MP3 currently is supported you must set this to BE_CONFIG_MP3 |
| format.mp3.dwSampleRate | Samplerate in Hz for MP3 file. This can be set to either 32000, 44100 or 48000. |
| format.mp3.byMode | Stereomode for MP3 file. This can be either BE_MP3_MODE_STEREO, BE_MP3_MODE_DUALCHANNEL or BE_MP3_MODE_MONO. |
| format.mp3.bitrate | Bitrate (i.e. size) of MP3 file in kBit/s. Allowed bitrates are: 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256 and 320. |
| format.mp3.bCopyright | If this is set to TRUE the Copyright bit in the MP3 stream will be set. |
| format.mp3.bCRC | Set this to TRUE in order to enable CRC-checksum in the bitstream. |
| format.mp3.bOriginal | If this is set to TRUE the Original bit in the MP3 stream will be set. |
| format.mp3.bPrivate | If this is set to TRUE the Private bit in the MP3 stream will be set. |
beInitStream()
| Synopsis: | BE_ERR beInitStream( PBE_CONFIG pbeConfig, PDWORD dwSamples, PDWORD dwBufferSize, PHBE_STREAM phbeStream ) | ||||||||
| Parameters: |
|
||||||||
| Description: | This function is the first to call before starting an encoding stream. |
beEncodeChunk()
| Synopsis: | BE_ERR beEncodeChunk( HBE_STREAM hbeStream, DWORD nSamples, PSHORT pSamples, PBYTE pOutput, PDWORD pdwOutput ) | ||||||||||
| Parameters: |
|
||||||||||
| Description: | Encodes a chunk of samples. Please note that if you have set the output to generate mono MP3 files you must feed beEncodeChunk() with mono samples! |
beDeinitStream()
| Synopsis: | BE_ERR beDeinitStream( HBE_STREAM hbeStream, PBYTE pOutput, PDWORD pdwOutput ) | ||||||
| Parameters: |
|
||||||
| Description: | This function should be called after encoding the last chunk in order to flush the encoder. It writes any encoded data that still might be left inside the encoder to the output buffer. This function should NOT be called unless you have encoded all of the chunks in your stream. |
beCloseStream()
| Synopsis: | BE_ERR beCloseStream( HBE_STREAM hbeStream ) | ||
| Parameters: |
|
||
| Description: | Last function to be called when finished encoding a stream. Should unlike beDeinitStream() also be called if the encoding is canceled. |

| Synopsis: | VOID beVersion( PBE_VERSION pbeVersion ) | ||
| Parameters: |
|
||
| Description: | Returns information like version numbers (both of the DLL and encoding engine), release date and URL for BladeEnc's homepage. All this information should be made available to the user of your product through a dialog box or something similar. |

The combination of redcurrants and fresh mint makes this the perfect condiment to serve with lamb. Use it to add depth to gravy too.
Wash the redcurrants and put them, stalks and all, into a large preserving pan along with 500ml/18fl oz water and the mint sprig. Slowly bring to the boil.
Stir and press the redcurrants to break down the fruit.
Remove the pan from the heat and cool slightly. Tie a jelly bag (or a clean sheet of muslin) to something appropriate so it can dangle over a bowl. Carefully pour the contents into the jelly bag (or muslin). Cover and leave to drip overnight - do not stir or squeeze the jelly bag.
When all the juice has dripped through, transfer the juice to a preserving pan, along with the sugar and lemon juice.
Put a plate in the freezer.
Place the pan over a gentle heat and cook, stirring frequently, until the sugar has dissolved.
Bring to a rapid boil and boil for 10-15 minutes, or until setting point is reached. To test the setting point, remove the pan from the heat. Take your saucer from the freezer and place a drop of jelly onto the cold plate. After a few seconds push the jelly with your finger. If the jelly surface wrinkles then it has reached setting point and is ready. If it slides about as a liquid, then it hasn't reached setting point and should be returned to the heat and boiled for a few more minutes before testing again.
Remove from the heat and stir in the chopped mint.
Cool slightly before pouring into sterilised jars.

Bithumb Seeking Indian Partner for its Blockchain Platform
by Ali RazaProminent Korean crypto exchange, Bithumb, has plans to create a new blockchain platform, and it is currently searching for Indian partners to collaborate with.
Bithumb is coming to India. According to the major cryptocurrency trading platform’s recent announcement, Bithumb plans to develop a new blockchain platform specially designed for India and its growing number of crypto users. The project is named the Bithumb Chain, and it will be available for many Indian startups, companies, as well as the government itself.
It will allow them to create various blockchain-based products, services, and more.
Bithumb Searching for Indian partners
The project was announced only yesterday, in South Korea’s capital of Seoul, during the Bithumb Family Conference. The exchange’s Vice President, Vincent Poon, stated that the firm currently doesn’t have a partner in India and that they are willing to collaborate with any interested party.
Poon also stated that he sees India as a country with a lot of potential, and limitless possibilities when it comes to crypto and blockchain applications and use. Of course, India is still currently debating the legality of cryptocurrency, and it remains unknown where such debates might lead in the future. However, the situation seems a bit less tense when it comes to blockchain technology.
In fact, Poon stated that India’s developer talent is nothing short of impressive, especially when it comes to blockchain technology and its applications.
What will the Platform Deal With?
For now, Bithumb has not revealed technical details regarding the platform. However, Poon stated that the project would let developers integrate their own projects with it, without having to ‘reinvent the wheel’ to do so.
Furthermore, there still remains the matter of the country’s stance towards cryptocurrency. Poon noted that India’s government has yet to pass a bill that would ultimately decide the fate of crypto within the country.
He also stated that Bithumb’s new platform would be useful for many different industries, and adapted to various use cases. Right now, they are still in the early stages, and the company is looking for someone to partner up with and let them use Bithumb Chain as part of their products.
As for Bithumb itself, it still has no plans to start its own project in India, at least not before the future of cryptocurrency in the country is decided.
What do you think about Bithumb’s new project? Do you think that Bithumb Chain can help Indian companies adopt blockchain technology? Let us know your thoughts in the comments below.

Curiosity is what drives me most of the time, the love for knowing how things work and the willing to create unique stuff is what makes me keep investing my time on learning new technologies and programing skills.
All problems can be solved if you are determined and patient enough.
I worked for 9 months in the development of new technologies of the company, working both in the LUA backend and in the GWTP frontend in Java, creating a new tool to increase the productivity of business work.
I worked for 2 years in the maintenance, development and integration of an Incubated startup by Take.net called POP Recarga. I worked on the development and documentation of several tools and applications using .NET / C #, JavaScript and Python. Among the works I developed ChatBots, websites, documentations/wikis, enhancements and integrations between Web applications.
I worked in different sectors of the company, focusing mainly on the Backend and DevOps area, creating CI/CD pipelines using Jenkins and other AWS tools. Assessing bottlenecks and reducing computational cost while maintaining efficiency and functionality. In addition to structuring the new Micro-Services and working on several backend/frontend projects.
I worked in different sectors of the company, focusing mainly on the Mobile and DevOps area, creating CI/CD pipelines using Github Actions and GA API. Also created a totally customized White Label flutter builder app system, using NODE/VUE + S3 + Flutter + Fastlane to Deliver new updates and apps as fast as possible without needing much code.

Game Of Thrones star says there's an alternate ending to the series
by Ciara WalshGame of Thrones' Kristofer Hivju has revealed an alternate ending was filmed for the finale of the show.
It's been more than six months since the HBO epic came to an end.
But the series' eight season proved to be pretty divisive, with many fans even petitioning to have the last six episodes remade.
Kristofer, who played Tormund Giantsbane, recently told Metro how things could have played out way differently. Namely, because an alternate ending to the series was filmed - although it's unlikely fans will ever see it.
He told Metro: "Well, we shot an alternative ending. That was mostly for fun but I don't know if I'm allowed to tell you about that."
Although he kept quiet as to what the alternate ending involved, he did admit that it was "fun".
Hivju's admission comes a few weeks after HBO ordered a Game of Thrones prequel series, House of the Dragon.
The new series, which will be set 300 years before the events of the aforementioned show, will tell the story of the Targaryens in Westeros, long before the Mad King, Daenery's reign, and her eventual fall from grace.
Series one will have 10 episodes and will be co-produced by Game of Thrones author George RR Martin, as well as Ryan Condal and Miguel Sapochnik.


SkyTrain union, company return to bargaining table while bus drivers set to strike
by The Canadian PressThe union representing 900 SkyTrain workers and their employer are returning to the bargaining table, as another Metro Vancouver transit union remains poised to strike next week.
TransLink’s BC Rapid Transit Company and CUPE 7000 both say in statements that they have agreed to resume collective bargaining talks this weekend.
The announcement comes the day after 96.8 per cent of members voted in favour of job action if a contract isn’t reached.
Eight days of mediation beginning Thursday have been booked, but CUPE 7000 president Tony Rebelo says the company has indicated it’s willing to “take another look at substantial issues in advance of mediation.”
Michel Ladrak, president of BC Rapid Transit Company, calls the resumption of talks “a very positive step forward” in a statement.
CUPE 7000 represents approximately 900 SkyTrain workers including attendants, control operators, administrators, maintenance workers and technical staff.
The last CUPE 7000 contract expired on Aug. 31, 2019.
Canada Line and West Coast Express are not affected by these negotiations.
Meanwhile, TransLink’s Coast Mountain Bus Company and Unifor, which represents Seabus operators, bus drivers and mechanical staff, remain in a deadlock.
Unifor, which represents the 5,000 workers, says unless it reaches a settlement with TransLink’s Coast Mountain Bus Company in the coming days, it will stage the three-day walk out.
Coast Mountain says in a statement more than 350,000 people take the bus daily in Metro Vancouver and they should not be caught in the middle of this dispute.
This report by The Canadian Press was first published Nov. 22, 2019.

{% extends "base.html" %} {% block title %}D&D Weapons | Home{% endblock %} {% block content %}
A +1 weapon is a kingly gift in the newest edition of Dungeons and Dragons. And yet the allure of killing monsters and taking their stuff never grows old. What magical weapons should we line the tombs and treasure chests that we put in the path of our players' early adventures? I have created this generator that uses a table of 100 properties to generate nearly 10,000 weak but unique magical weapons. These are the kind of weapons that are better than nothing, but each weaker than a +1 weapon.
+1 weapons are also guilty of being boring. Each property in this generator lends to an evocative name, either to be used as-is or to offer inspiration for something better. And that's it. You won't find paragraphs of fiction describing the back story of these weapons, nor dialogue from a scene depicting its origin. Just concise, evocative names to get your gears turning.
Whether you use these humble items as-is, or they serve as to inspire you, I hope you enjoy!

- 1 1/2 cups milk
- 1/2 cups mascarpone
- 1/2 tsp pink salt
- 1 lb Black Mission Figs
- 1/2 cup brown sugar
- 2-4 tbsp water
- 1 1/2 cups heavy cream
- 1/3 granulated sugar
- 2 egg yolks
- 1 lemon, juiced
- 2 tbsp butter
- 1 cup honey roasted pecans, roughly chopped
For the fig-swirl: Melt butter over medium heat in a saucepan. Add brown sugar and stir to disolve. Halve all of the figs and toss in the saucepan with water and lemon juice. Cook over medium heat, stirring frequently, until you have a chunky-jammy mixture. Add salt with one or two stirs, set aside and let cool completely.
Ice cream: In a small pot over medium heat, combine milk, and granulated sugar until sugar is completely dissolved and the milk is just barely lukewarm. Whisk in the egg yolks. Set mixture in the fridge and wait until the fig mixture is cooled.
Using an ice cream machine, pour liquids into the frozen basin and process according to manufacturer instructions, i.e., let spin and thicken for 20 minutes before adding mascarpone, fig jam mixture, and the nuts. Continue to preocess for +/- 10 minutes. Pour semi-frozen mixture into a pyrex dish or glass tupperware. Freeze for at least two hours before serving.


How do I archive inactive projects including history?
- Select one computer as your archive.
- Join all projects from that computer (it's enough to join as observer--no license needed)
- Ask the member with the longest history in a given project to export his or her history
- Import this history on your archive computer
- Have everybody else defect from the unused projects (before the last person defects, make sure the archived version is selected as administrator).
Any time you want to revive an abandoned project, simply let people join it again.
This is also a great way to back up your projects.

Models help you structure your work with data by providing several objects and functions. The key ones are Dataset and Record – a Dataset being a collection of Records. Additionally, there is a a Field object for describing the columns of a Dataset, a Query object for describing queries, and a Facet object for holding summary information about a Field (or multiple Fields).
All the models are Backbone models, that is they extend Backbone.Model. Note, however, that they do not ‘sync’ (load/save) like normal Backbone models.
A Dataset is the central object in Recline. Standard usage is:
var dataset = new recline.model.Dataset({
// general metadata e.g.
id: ...
title: ...
// information about data source e.g.
url: http://url.to.my.data.endpoint/
// backend string or object
backend: a string identifying the backend we are using - see below
});
// initialize dataset with data from the backend.
dataset.fetch();

object which stores current queryState. queryState may be edited by other components (e.g. a query editor view) changes will trigger a Dataset query.Facet
sdataset.query(queryObj)
queryObj
is an object following the query
specification below.
A Record is a single entry or row in a dataset. A Record needs little more than what is provided by the standard Backbone Model object. In general, you will never create a Record directly – they will get created for you by Datasets from query results.
A Field should have the following attributes as standard:
var field = new Field({
// a unique identifer for this field- usually this should match the key in the records hash
id: 'my-field-id'
// (optional: defaults to id) the visible label used for this field
label: 'My Field Name',
// (optional: defaults to string) the type of the data in this field.
// For list of type names see below
type: 'string',
// (optional - defaults to null) used to indicate how the data should be
// formatted. See below.
format: null,
// (default: false) attribute indicating this field has no backend data but
// is just derived from other fields (see below).
is_derived: false
The type attribute is a string indicating the type of this field.
Types are based on the type set of json-schmea with a few minor additions and modifications (cf other type lists include those in Elasticsearch).
The type list is as follows (brackets indicate possible aliases for specific types - these types will be recognized and normalized to the default type name for that type):
One can customize the rendering of fields in the user interface and elsewhere by setting a renderer function on the field. You do this by setting a field attribute:
myfield.renderer = myRenderFunction;
Your renderer function should have the following signature:
function(value, field, record)
Where the arguments passed in are as follows:
value
: the value of the cell (record value for this field)field
: corresponding Field
objectrecord
: is the Record
object (as simple JS object)Note that implementing functions can ignore arguments (e.g. function(value) would be a valid formatter function).
To guide the behaviour of renderers we have type and format information. Example types and formats are:
Default renderers are provided - see the source for details, but a few examples are:
type = string
type = float
Some fields may be ‘dervied’ from other fields. This allows you to define an entirely new value for data in this field. This provides support for a) ‘derived/computed’ fields: i.e. fields whose data are functions of the data in other fields b) transforming the value of this field prior to rendering.
To use derived fields set a deriver
function on the Field. This function will be used to derive/compute the value of data in this field as a function of this field’s value (if any) and the current record. It’s signature and behaviour is the same as for renderer.
Query instances encapsulate a query to the backend (see query method on backend). Useful both for creating queries and for storing and manipulating query state - e.g. from a query editor).
Query structure should follow that of ElasticSearch query language.
NB: It is up to specific backends how to implement and support this query structure. Different backends might choose to implement things differently or not support certain features. Please check your backend for details.
Query object has the following key attributes:
Additions:
q: either straight text or a hash will map directly onto a query_string query in backend
filters: array of ElasticSearch filters. These will be and-ed together for execution.
Sort structure is inspired by http://www.elasticsearch.org/guide/reference/api/search/sort.html but with some standardization.
Sort structure must be as follows:
"sort" : [
{ field: "post_date", "order" : "desc"},
{ field: "user" },
{ "name" : "desc" },
{ "age" : "desc" },
{"_score": null}
]
If order is omitted it is assumed to be “desc” except in the case of score.score is a special case which is used for match score if that is supported by the backend.
{ q: 'quick brown fox', filters: [ { term: { 'owner': 'jones' } } ] }
Structure of a facet follows that of Facet results in ElasticSearch, see: http://www.elasticsearch.org/guide/reference/api/search/facets/
Specifically the object structure of a facet looks like (there is one addition compared to ElasticSearch: the “id” field which corresponds to the key used to specify this facet in the facet query):
{
id: "id-of-facet",
// type of this facet (terms, range, histogram etc)
_type : "terms",
// total number of tokens in the facet
total: 5,
// @property {number} number of records which have no value for the field
missing : 0,
// number of facet values not included in the returned facets
other: 0,
// term object ({term: , count: ...})
terms: [ {
"term" : "foo",
"count" : 2
}, {
"term" : "bar",
"count" : 2
}, {
"term" : "baz",
"count" : 1
}
]
}

Zyz Sailing Team is a group of students of my university led by prof. Antonio Mancuso, whose objective is the design and realisation of sail boats, in order to participate in a competition with other similar boats from several Italian and European universities. The main goal of my internship was the design of hydrofoils for a 5-meters catamaran, to be realised with carbon fibre skin and a 1 semi-monocoque structure to ensure stiffness.
The work carried out has been published in Ansys Blog where you can more details and videos about the competition.
I am now attending the studies of Aerospace Engineering, a two-years course which examines not only the main aerospace subjects, like structures, materials, aeronautic technology, flight dynamics, incompressible and compressible aerodynamics, automatic controls, propulsion, computational analysis for structures and aerodynamics, aircraft design, but also complementary subjects, such as experimental stress-strain analysis of structures, with particular focus on strain gauges, photoelasticity and thermoelasticity, corrosion and protection of aerospace materials, robotic systems, dynamics of structures, process design, composite materials. Without having completed my studies, I can sincerely affirm that the more I proceed, the more I become passionate and enthusiastic about this world.
Bachelor of Mechanical and Aeronautical Engineering, first class with honors. The BSc thesis on "Obstacle Avoidance in the UAS" explored the basics and the recent development in path planning and obstacle avoidance algorithms in the field of Unmanned Air Systems (UAS). It was conceived as a summary of several techniques, and the goal was to provide an analysis of advantages, disadvantages, prospects of future implementation, and to show some important achievements. This perfectly integrated my first years of studies on the foundations of engineering, so that at the end of my bachelor’s degree I have experienced a rich path through both the basic scientific disciplines and the advanced frontiers of progress and innovation.
I enjoy most of my time being outdoors. My personal interests are sailing, trekking and Music.

Use of the Access Control Editor | |
Several directories and domains, such as /status /debug and /admin must be protected, or the installation will not be secure from remote attack. As distributed, Tclhttpd defaults to safe but restrictive permissions.
Opening access to these sensitive facilities on a new installation requires that the admin create system-wide user and group files, and .htaccess files in the various directories which need to be protected.
The Access Control Editor maintains:
The per-directory control file, as detailed here
consisting of lines formatted as: group_name: member, member ...
consisting of lines formatted as user_name: password
As it is necessary to have an administrative password before safely administering access control, some bootstrapping is required.
To begin to administer access control through the editor one may log in as the user webmaster with the password in /tmp/tclhttpd.default.
The first thing one should do is decide where the installation's user and group files will reside and create a password for webmaster.
Note: It is crucial that the user file not be visible from the web - it must not reside under the document root!
Once the user and group files are created and populated with values, you can secure the Access Control Editor by editing the directory htaccess.
Having secured /htaccess, one can freely use it to secure any directory or domain.
Several configuration options in tclhttpd.rc control how authentication occurs:
If this is undefined, a new random password is created in /tmp/tclhttpd.default every time the server is restarted. If it is defined, it is the plaintext default password for a user called webmaster, who has (by default) complete access to the Access Control Editor.
After boostrapping, it would be advisable to set this value to ""
The default name of the file containing web user passwords (note, this should be different from your system's default password file, if any)
The default name of a file containing web groups.

Experiments with GraalVM - Part 1 : Introduction
GraalVM is a new open source project by Oracle which is trying to make Java VM an universal VM to run all the major languages. Before GraalVM, there were already few languages like Scala, Closure which targeted JVM as their runtime. This has been hugely successful for those languages. GraalVM takes this idea further and makes it easy to target JVM so that many more languages can coexist on JVM.
GraalVM is around from 2014 as a research project. It’s been used in production by Twitter from 2017. But for general public, it became production ready in latter half of 2019.
In this series posts, I will be exploring what GraalVM can bring to JVM ecosystem. This is the first post in the series which introduces the GraalVM. You can read all the posts in the series here.
What is GraalVM
From GraalVM website
GraalVM offers a comprehensive ecosystem supporting a large set of languages (Java and other JVM-based languages, JavaScript, Ruby, Python, R, WebAssembly, C/C++ and other LLVM-based languages) and running them in different deployment scenarios (OpenJDK, Node.js, Oracle Database, or standalone).
They are essentially saying that, it’s a ecosystem which has Java VM at it’s heart and want to support run wide variety of languages on top of it.
Why Multiple Languages
Why does some one care about running their languages on JVM? The below are some reasons
Server Tuned VM
JVM has been battle tested over years on server. This can benefit systems like Node.js, javascript server framework, which currently runs on V8 which is optimised for client environment like browser. Also languages like Ruby already do this. That’s why there are lot of companies which run JRuby implementation. GraalVM makes this much easier and supports more languages with less effort.
Polyglot Support
As we can now run multiple languages on same VM, we can mix and match these languages. This is very powerful. For example, we can now extend capability of a compiled language like Java, with interpreted language like Javascript. This combination makes it much more powerful than running single language. We will discuss more about this in future posts.
Libraries of Java Ecosystem
One of the reason Scala adopted JVM is for it’s rich ecosystem. Able to run on the JVM makes all the Java libraries available to Scala. Now they are going to be available to all the languages which run on graalVM.
There are many more advantages to GraalVM than listed above. You can read more about it here.
GraalVM Architecture
The above picture shows the architecture of graalvm.
From Above Architecture , the below are the main components
-
Java Hotspot VM : It’s heart of the architecture. Everything is powered by Java VM. Supported from Java 8 onwards.
-
Graal Compiler : The Graal Compiler which is responsible for generating the byte code from AST generated from above layers
-
Truffle Framework : A framework which allows defining interpreters for different languages in a AST model. This standard AST model between languages makes it polyglot
References

Conclusion
GraalVM brings a new era in VM’s. It’s positioning the JVM as center of all the popular language runtime. This makes JVM ecosystem exciting again.

This step-by-step tutorial will guide you through the setup of Stratosphere using Amazon Elastic MapReduce.
Background
Amazon Elastic MapReduce (Amazon EMR) is part of Amazon Web services. EMR allows to create Hadoop clusters that analyze data stored in Amazon S3 (AWS’ cloud storage). Stratosphere runs on top of Hadoop using the recently released cluster resource manager YARN. YARN allows to use many different data analysis tools in your cluster side by side. Tools that run with YARN are, for example Apache Giraph, Spark or HBase. Stratosphere also runs on YARN and that’s the approach for this tutorial.
1. Step: Login to AWS and prepare secure access
- Log in to the AWS Console
You need to have SSH keys to access the Hadoop master node. If you do not have keys for your computer, generate them:
- Select EC2 and click on "Key Pairs" in the "NETWORK & SECURITY" section.
- Click on "Create Key Pair" and give it a name
- After pressing "Yes" it will download a .pem file.
- Change the permissions of the .pem file
chmod og-rwx ~/work-laptop.pem
2. Step: Create your Hadoop Cluster in the cloud
- Select Elastic MapReduce from the AWS console
- Click the blue “Create cluster” button.
- Choose a Cluster name
- You can let the other settings remain unchanged (termination protection, logging, debugging)
- For the Hadoop distribution, it is very important to choose one with YARN support. We use 3.0.3 (Hadoop 2.2.0) (the minor version might change over time)
- Remove all applications to be installed (unless you want to use them)
- Choose the instance types you want to start. Stratosphere runs fine with m1.large instances. Core and Task instances both run Stratosphere, but only core instances contain HDFS data nodes.
- Choose the EC2 key pair you've created in the previous step!
- Thats it! You can now press the “Create cluster” button at the end of the form to boot it!
3. Step: Launch Stratosphere
You might need to wait a few minutes until Amazon started your cluster. (You can monitor the progress of the instances in EC2). Use the refresh button in the top right corner.
You see that the master is up if the field Master public DNS contains a value (first line), connect to it using SSH.
ssh hadoop@<your master public DNS> -i <path to your .pem>
# for my example, it looks like this:
ssh<EMAIL_ADDRESS>-i ~/Downloads/work-laptop.pem
(Windows users have to follow these instructions to SSH into the machine running the master.) </br></br> Once connected to the master, download and start Stratosphere for YARN:
- Download and extract Stratosphere-YARN
- Start Stratosphere in the cluster using Hadoop YARN

Once the output has changed from
JobManager is now running on N/A:6123
to
JobManager is now running on ip-172-31-13-68.us-west-2.compute.internal:6123
Stratosphere has started the JobManager. It will take a few seconds until the TaskManagers (workers) have connected to the JobManager. To see how many TaskManagers connected, you have to access the JobManager’s web interface. Follow the steps below to do that …
4. Step: Launch a Stratosphere Job
This step shows how to submit and monitor a Stratosphere Job in the Amazon Cloud.
- Open an additional terminal and connect again to the master of your cluster. We recommend to create a SOCKS-proxy with your SSH that allows you to easily connect into the cluster. (If you've already a VPN setup with EC2, you can probably use that as well.)
- Configure a browser to use the SOCKS proxy. Open a browser with SOCKS proxy support (such as Firefox). Ideally, do not use your primary browser for this, since ALL traffic will be routed through Amazon.
ssh -D localhost:2001 hadoop@<your master dns name> -i <your pem file>
-D localhost:2001
argument: It opens a SOCKS proxy on your computer allowing any application to use it to communicate through the proxy via an SSH tunnel to the master node. This allows you to access all services in your EMR cluster, such as the HDFS NameNode or the YARN web interface.
Since you’re connected to the master now, you can open several web interfaces:
YARN Resource Manager: http://<masterIPAddress>:9026/
HDFS NameNode: http://<masterIPAddress>:9101/
You find the masterIPAddress
by entering ifconfig
into the terminal:
[hadoop@ip-172-31-38-95 ~]$ ifconfig
eth0 Link encap:Ethernet HWaddr 02:CF:8E:CB:28:B2
inet addr:<IP_ADDRESS> Bcast:<IP_ADDRESS> Mask:<IP_ADDRESS>
inet6 addr: fe80::cf:8eff:fecb:28b2/64 Scope:Link
RX bytes:166314967 (158.6 MiB) TX bytes:89319246 (85.1 MiB)
Optional: If you want to use the hostnames within your Firefox (that also makes the NameNode links work), you have to enable DNS resolution over the SOCKS proxy. Open the Firefox config about:config
and set network.proxy.socks_remote_dns
to true
.
The YARN ResourceManager also allows you to connect to Stratosphere’s JobManager web interface. Click the ApplicationMaster link in the “Tracking UI” column.
To run the Wordcount example, you have to upload some sample data.
# download a text
wget http://www.gnu.org/licenses/gpl.txt
# upload it to HDFS:
hadoop fs -copyFromLocal gpl.txt /input
To run a Job, enter the following command into the master’s command line:
# optional: go to the extracted directory
cd stratosphere-yarn-0.5-SNAPSHOT/
# run the wordcount example
./bin/stratosphere run -w -j examples/stratosphere-java-examples-0.5-SNAPSHOT-WordCount.jar -a 16 hdfs:///input hdfs:///output
Make sure that the number of TaskManager’s have connected to the JobManager.
Lets go through the command in detail:
./bin/stratosphere
is the standard launcher for Stratosphere jobs from the command line- The
-w
flag stands for “wait”. It is a very useful to track the progress of the job. -j examples/stratosphere-java-examples-0.5-SNAPSHOT-WordCount.jar
the-j
command sets the jar file containing the job. If you have you own application, place your Jar-file here.-a 16 hdfs:///input hdfs:///output
the-a
command specifies the Job-specific arguments. In this case, the wordcount expects the following input<numSubStasks> <input> <output>
.
You can monitor the progress of your job in the JobManager webinterface. Once the job has finished (which should be the case after less than 10 seconds), you can analyze it there. Inspect the result in HDFS using:
hadoop fs -tail /output
If you want to shut down the whole cluster in the cloud, use Amazon’s webinterface and click on “Terminate cluster”. If you just want to stop the YARN session, press CTRL+C in the terminal. The Stratosphere instances will be killed by YARN.

Since January 2013 the BlueSystems office in Barcelona has been open for anybody related to KDE to join us, a great example has been Albert Vaca who has been coming to the office to work on his GSoC, some other examples are the mini Framework sprints that have been held in the office.
Now, we are happy to announce that the Office is finally ready to hold sprints up to 30 people, and our intention is to hold as many sprints/KDE Events as possible!
The office is situated in Barcelona centre:
And it has all the commodities needed for a sprint:
So, if you are thinking on organizing a sprint know that our office is always available!

OCHamcrest

OCHamcrest is:
Matchers are useful for a variety of purposes, such as UI validation. But they're most commonly used for writing unit tests that are expressive and flexible.
OCHamcrest is used for both Mac and iOS development with:
Rather than build OCHamcrest yourself, I recommend you use the pre-built release available in Downloads. This works for projects using Automatic Reference Counting (ARC) as well as for projects using traditional memory management.
(But if you still want to build OCHamcrest yourself, go into the Source folder and execute MakeDistribution.sh
from Terminal.)
The steps vary slightly depending on whether your project is a Mac project or an iOS project:
Mac:
#define HC_SHORTHAND #import <OCHamcrest/OCHamcrest.h>
Note: If your Console shows
otest[57510:203] *** NSTask: Task create for path '...' failed: 22, "Invalid argument". Terminating temporary process.
double-check your Copy Files phase.
iOS:
#define HC_SHORTHAND #import <OCHamcrestIOS/OCHamcrestIOS.h>
We'll start by writing a very simple Xcode unit test, but instead of using OCUnit's STAssertEqualObjects
function, we'll use OCHamcrest's assertThat
construct and a predefined matcher:
#import <SenTestingKit/SenTestingKit.h> #define HC_SHORTHAND #import <OCHamcrest/OCHamcrest.h> @interface BiscuitTest : SenTestCase @end @implementation BiscuitTest - (void)testEquals { Biscuit* theBiscuit = [Biscuit biscuitNamed:@"Ginger"]; Biscuit* myBiscuit = [Biscuit biscuitNamed:@"Ginger"]; assertThat(theBiscuit, equalTo(myBiscuit)); } @end
The assertThat function is a stylized sentence for making a test assertion. In this example, the subject of the assertion is the object theBiscuit
, which is the first method parameter. The second method parameter is a matcher for Biscuit
objects, here a matcher that checks one object is equal to another using the -isEqual
: method. The test passes since the Biscuit
class defines an -isEqual
: method.
OCHamcrest's functions are actually declared with an "HC" package prefix (such as HC_assertThat
and HC_equalTo
) to avoid name clashes. To make test writing faster and test code more legible, shorthand macros are provided if HC_SHORTHAND
is defined before including the OCHamcrest header. For example, instead of writing HC_assertThat, simply write assertThat.
OCHamcrest comes with a library of useful matchers:
-description
nil
, or not nil
int
) The arguments for many of these matchers accept not just a matching value, but another matcher, so matchers can be composed for greater flexibility. For example, only_contains(endsWith(@"."))
will match any collection where every item is a string ending with period.
OCHamcrest strives to make your tests as readable as possible. For example, the is matcher is a wrapper that doesn't add any extra behavior to the underlying matcher. The following assertions are all equivalent:
assertThat(theBiscuit, equalTo(myBiscuit)); assertThat(theBiscuit, is(equalTo(myBiscuit))); assertThat(theBiscuit, is(myBiscuit));
A key feature of OCHamcrest is its extensibility. See Writing custom matchers for an example of how to write your own matchers.
