Scalar Arguments .. CHARACTER JOBZ, RANGE, UPLO INTEGER IL, INFO, IU, KA, KB, LDAB, LDBB, LDQ, LDZ, M, $ N REAL ABSTOL, VL, VU * .. * .. Array Arguments .. INTEGER IFAIL( * ), IWORK( * ) REAL RWORK( * ), W( * ) COMPLEX AB( LDAB, * ), BB( LDBB, * ), Q( LDQ, * ), $ WORK( * ), Z( LDZ, * ) * .. * * Purpose * ======= * * CHBGVX computes all the eigenvalues, and optionally, the eigenvectors * of a complex generalized Hermitian-definite banded eigenproblem, of * the form A*x=(lambda)*B*x. Here A and B are assumed to be Hermitian * and banded, and B is also positive definite. Eigenvalues and * eigenvectors can be selected by specifying either all eigenvalues, * a range of values or a range of indices for the desired eigenvalues. * * Arguments * ========= * * JOBZ (input) CHARACTER*1 * = 'N': Compute eigenvalues only; * = 'V': Compute eigenvalues and eigenvectors. * * RANGE (input) CHARACTER*1 * = 'A': all eigenvalues will be found; * = 'V': all eigenvalues in the half-open interval (VL,VU] * will be found; * = 'I': the IL-th through IU-th eigenvalues will be found. * * UPLO (input) CHARACTER*1 * = 'U': Upper triangles of A and B are stored; * = 'L': Lower triangles of A and B are stored. * * N (input) INTEGER * The order of the matrices A and B. N >= 0. * * KA (input) INTEGER * The number of superdiagonals of the matrix A if UPLO = 'U', * or the number of subdiagonals if UPLO = 'L'. KA >= 0. * * KB (input) INTEGER * The number of superdiagonals of the matrix B if UPLO = 'U', * or the number of subdiagonals if UPLO = 'L'. KB >= 0. * * AB (input/output) COMPLEX array, dimension (LDAB, N) * On entry, the upper or lower triangle of the Hermitian band * matrix A, stored in the first ka+1 rows of the array. The * j-th column of A is stored in the j-th column of the array AB * as follows: * if UPLO = 'U', AB(ka+1+i-j,j) = A(i,j) for max(1,j-ka)<=i<=j; * if UPLO = 'L', AB(1+i-j,j) = A(i,j) for j<=i<=min(n,j+ka). * * On exit, the contents of AB are destroyed. * * LDAB (input) INTEGER * The leading dimension of the array AB. LDAB >= KA+1. * * BB (input/output) COMPLEX array, dimension (LDBB, N) * On entry, the upper or lower triangle of the Hermitian band * matrix B, stored in the first kb+1 rows of the array. The * j-th column of B is stored in the j-th column of the array BB * as follows: * if UPLO = 'U', BB(kb+1+i-j,j) = B(i,j) for max(1,j-kb)<=i<=j; * if UPLO = 'L', BB(1+i-j,j) = B(i,j) for j<=i<=min(n,j+kb). * * On exit, the factor S from the split Cholesky factorization * B = S**H*S, as returned by CPBSTF. * * LDBB (input) INTEGER * The leading dimension of the array BB. LDBB >= KB+1. * * Q (output) COMPLEX array, dimension (LDQ, N) * If JOBZ = 'V', the n-by-n matrix used in the reduction of * A*x = (lambda)*B*x to standard form, i.e. C*x = (lambda)*x, * and consequently C to tridiagonal form. * If JOBZ = 'N', the array Q is not referenced. * * LDQ (input) INTEGER * The leading dimension of the array Q. If JOBZ = 'N', * LDQ >= 1. If JOBZ = 'V', LDQ >= max(1,N). * * VL (input) REAL * VU (input) REAL * If RANGE='V', the lower and upper bounds of the interval to * be searched for eigenvalues. VL < VU. * Not referenced if RANGE = 'A' or 'I'. * * IL (input) INTEGER * IU (input) INTEGER * If RANGE='I', the indices (in ascending order) of the * smallest and largest eigenvalues to be returned. * 1 <= IL <= IU <= N, if N > 0; IL = 1 and IU = 0 if N = 0. * Not referenced if RANGE = 'A' or 'V'. * * ABSTOL (input) REAL * The absolute error tolerance for the eigenvalues. * An approximate eigenvalue is accepted as converged * when it is determined to lie in an interval [a,b] * of width less than or equal to * * ABSTOL + EPS * max( |a|,|b| ) , * * where EPS is the machine precision. If ABSTOL is less than * or equal to zero, then EPS*|T| will be used in its place, * where |T| is the 1-norm of the tridiagonal matrix obtained * by reducing AP to tridiagonal form. * * Eigenvalues will be computed most accurately when ABSTOL is * set to twice the underflow threshold 2*SLAMCH('S'), not zero. * If this routine returns with INFO>0, indicating that some * eigenvectors did not converge, try setting ABSTOL to * 2*SLAMCH('S'). * * M (output) INTEGER * The total number of eigenvalues found. 0 <= M <= N. * If RANGE = 'A', M = N, and if RANGE = 'I', M = IU-IL+1. * * W (output) REAL array, dimension (N) * If INFO = 0, the eigenvalues in ascending order. * * Z (output) COMPLEX array, dimension (LDZ, N) * If JOBZ = 'V', then if INFO = 0, Z contains the matrix Z of * eigenvectors, with the i-th column of Z holding the * eigenvector associated with W(i). The eigenvectors are * normalized so that Z**H*B*Z = I. * If JOBZ = 'N', then Z is not referenced. * * LDZ (input) INTEGER * The leading dimension of the array Z.

Curtin University used Lectopia to record lectures and
provide them to students for nearly a decade, but since
the acquisition of Lectopia by Echo360 and the product's
subsequent deprecation in favour of EchoSystem, Curtin
no longer uses Lectopia.
The servers will be taken offline after December 31, 2013,
and the fate of the data currently present on the legacy
system is unknown, though it is unlikely that it will
be made available to the public through other means.
This is an archive of the lectures.


For your 16th, I (with a lot of help from Dushyanth because I am still learning to code) have made you a website from scratch with some notes from your best friends and family. I hope this helps you realize just how loved you are and how none of us judge you for your rough times, but rather want to be by your side through it all. I hope it helps you realize that you have an entire support system at your disposal 24/7; a whole band of cheerleaders.


First Analyze your data using the link button on the left. This will provide you with options for setting thresholds to roughly guage the number of DE genes in your dataset. This is NOT a statistical process.  To observe the effect of various cuttoffs, you can choose to produce a tally plot (see plot descriptions). This will also produce a formatted plottable dataset that can be used when making plots.

I threw this one in for anti-QF purposes. It's gammon save so the natural thing to do is to play safe, and the top play of the rollout is to play safe. (Clearing the 7pt is better than clearing the 8pt because we might still want to attack next turn.)

About Cambridge Women Take the Streets
Women Take the Streets focuses on disparities in the representation of women who live or have lived in Cambridge, utilizing an Instagram filter,
streetmap, and profiles of women of Cambridge. About 248,000 feet of the streets of Cambrdige are named after men,
while 17,450 feet were named after women -- that is only 7% of what men have.
Our project attempts to fulfill Mei-Po Kwan’s feminist visualization design principles by grounding mapping practices in our everyday experience
of street signs. We incorporate qualitative and narrative components into the spatial representations of historical figures,
symbols which a pedestrian might otherwise never consider to be the result of a political process.
Our Instagram filter is one technique which, by augmenting reality, aligns with
Sandra Harding’s call for strong objectivity views. The filter works toward more inclusive knowledge production by literally centering the standpoints of
women who may have been excluded in their own times, and whose lives may have since gone without significant public commemoration.
D’Ignazio and Klein remind us to “emphasize representational strategies premised on multiplicity rather than binaries, and acknowledge the limits of any binaristic view”,
and suggest better representations of gender are continuous or multidimensional (Feminist Data Visualization). Though our map of Cambridge with color-coded street names attempts
to show disparities by gender, gender is better represented as a spectrum and not categories. In particular, though our dataset currently contains ascribed gender of historical figures
in a binary fashiom, we recognize the existence and need to commemorate the lives of non-binary people and transgender women. For more resources for learning about and teaching gender,
visit Teaching Tolerance.
Our interactive playing cards profile notable women from the Cambridge Women’s Heritage Project and research on enslaved peoples of Cambridge conducted by Grace Woodward.
You can print out the cards, or even add your own heroes!

For some time I discovered Arduino and I did a little 'bones with small simple projects and then sketches very simple and hassle, now I would like to go one step further and found a project that I would like to do, I have already created the pcb and soldered the components now I'm trying to program the microprocessor atmega 328 using compiler as Arduino.
Here is all the documentation and the sketch to be inserted into the chip with the various libraries and directories so far say I've gotten I downloaded the various libraries, but when I try to check the sketch gives me an error and I do not know what to do, tells me :
expected primary-expression before ")" token
On line 63 of the program
63 DallasTemperature sensors (& OneWire);
Thank you all
Re: Error compiling EmonGLCD sketch
Without knowing which sketch, I'm guessing that you don't have the 'OneWire' library installed.
http://openenergymonitor.org/emon/buildingblocks/installing-arduino-libr...
What the compiler is telling you is it does not understand "&oneWire", and I know that is a variable that is defined in that library. NOTE: it is "oneWire", not "OneWire". Here, "OneWire" is the type (like "int" or "double") and "oneWire" is a particular instance of that (like "y" or "Irms").
Line 63: "OneWire oneWire(ONE_WIRE_BUS);" is declaring an instance "oneWire" of some type "OneWire" that had been defined elsewhere - in fact it is a Class and it's defined in the library file OneWire.h.
Re: Error compiling EmonGLCD sketch
Hello Robert
I installed the library in the library OneWire Arduino but nothing gives me the same error
Re: Error compiling EmonGLCD sketch
To help us - help you...
I'm not this guy. You need to tell me more, like which sketch are you using.

Re: Error compiling EmonGLCD sketch
That still points to the compiler not being able to find the library. I have just copied your sketch from your post above, copied the two other .ino files (icons & templates) and it compiled immediately for me.
Is your OneWire library in the same Libraries directory as JeeLib and Emonlib?  (The libraries are read at start-up and held in memory. Leaving any IDE Window open means that the IDE does not start from nothing and does not read the libraries, which now include the new library, from disc.)
Re: Error compiling EmonGLCD sketch
Hello Robert
Today I could try to compile the program on another PC and everything worked properly , I can not understand why on my home PC is not working and it's all the same to this pc of my work , however, it does nothing I program it from here , the only thing tells me that memory is low and may not work properly .
Thanks again for your courtesy .
Christian
Re: Error compiling EmonGLCD sketch
It should be possible for you to take the compiler output from your work PC as a .hex file and load that into your GLCD using avrdude. However, I have never needed to do that so I cannot tell you the exact procedure.
If you can load on your work computer the drivers that the programmer needs, then you can of course take the GLCD to work and program it there.

Such for
statements are not supported under Java 1.4 and older.
Example:
for (int x: Arrays.asList(1, 2, 3)) { System.out.println(x); }
After the quick-fix is applied, the result looks like this:
for (Iterator<Integer> iterator = Arrays.asList(1, 2, 3).iterator(); iterator.hasNext(); ) { final int x = iterator.next(); System.out.println(x); }

"""Deletes extraneous files.
Without frequent monitoring, directories like /tmp and /var/log can frequently
grow to sizes that are difficult to manage because of clutter and files.
However, there has to be a middle ground between deleting thousands of files
one by one and :command:`rm -rf /tmp/`.
This module attempts that.
Initially tested on the android app Termux, this specifically deletes
directories with only month old sockets.
- :envvar:`$PREFIX`/tmp/nvim
- :envvar:`$PREFIX`/tmp/ssh
.. note:: On Ubuntu the big one is /var/log/journal so we might need to
remind the user for credentials. :func:`getpass.getpass`?
In addition, it felt like a good way to get more familiar with the new
:mod:`pathlib` module.
Concrete Roadmap
----------------
Up until now this has been fairly general and quite abstract.
Let's come up with a few pre-planned and clear endpoints.
One way to implement this module would be:
1. Compare packages that are installed to what's contained /usr/share/doc.
I have like 4500 folders in that directory and nowhere near that many
packages installed. Cruft and accumulation frequently doesn't get cleared
out of there correctly.

module Bitvector:sig
..end
A numeric value with a 2-complement binary representation. It is good for representing addresses, offsets and other numeric values.
Each value is attributed by a its bit-width. All arithmetic
operations over values are done modulo their widths. It is an
error to apply arithmetic operation to values with different
widths. Default implementations will raise a Width
exception,
however there exists a family of modules that provide arithmetic
operations lifted to an Or_error.t
monad. It is suggested to use
them, if you know what kind of operands you're expecting.
Bitvector should be considered as an number with an arbitrary
width. That means, that as with all numbers it is subject to
endianness. When we iterate over bitvector using some container
interface we always start from the byte with the lower
address. Depending on endianness it will be either least
significant bytes (little-endian), or most significant
(big-endian). Sometimes id does matter, sometimes it doesn't. In a
latter case you can just use a default native-endian
interface. But in a former case, please consider using explicit
modules, either Bytes_LE
or Bytes_BE
, even if you know that
your system is LE
. Things change.
Bits are always numbered from right to left, with least
significant bit having a zero index, and most significant having
index equal to width - 1
. That means, they're endianness
agnostic.
Size-monomorphic operations (as opposed to size-polymorphic
comparison) doesn't allow to compare two operands with different
sizes, and either raise exception or return Error
. If we would
have type safe interface, with type t
defined as type 'a t
,
where 'a
stands for size, then size-monomorphic operations will
have type 'a t -> 'a t -> _
, and size-polymorphic 'a t -> 'b t -> _
.
By default, size-polymorphic comparison is used (for rationale of
this decision look at the implementation of a hash function). To
understand the ordering relation one can think that a lexical
ordering is specified on a tuple (x,n)
, where x
is the number
and n
is the size. For example, the following sequence is in an
ascending order:
0x0:1, 0x0:32, 0x0:64, 0x1:1, 0x1:32, 0xD:4, 0xDEADBEEF:32
.
A size-monomorphic interfaced is exposed in a Mono
submodule. So
if you want a monomorphic map, then just use Mono.Map
module.
Note, Mono
submodule doesn't provide Table
, since we cannot
guarantee that all keys in a hash-table have equal size.
By default all numbers represented by a bitvector are considered
unsigned. This includes comparisons, e.g., of_int (-1) ~width:32
is greater than zero. If you need to perform signed operation, you
can use signed
operator to temporary cast your value to signed.
We use temporary to emphasize that, the signedness property won't
propagate to the result of the operation, e.g. result of the
following expression: Int_exn.(signed x / y)
will not be signed.
If any operand of a binary operation is signed, then a signed version of an operation is used.
Remember to use explicit casts, whenever you really need a signed representation. Examples:
let x = of_int ~-6 ~width:8
let y = to_int x (* y = 250 *)
let z = to_int (signed x) (* z = ~-6 *)
let zero = of_int 0 ~width:8
let p = x < zero (* p = false *)
let q = signed x < zero (* p = true *)
As a part of Identifiable
interface bitvector provides a pair of
complement functions: to_string
and of_string
, that provides
facilities to store bitvector as a human readable string, and to
restore it from string. The format of the representation is the
following (in EBNF):
repr = [sign], base, digit, {digit}, ":", size | true | false;
sign = "+" | "-";
base = "0x" | "0b" | "0o";
size = dec, {dec};
digit = dec | oct | hex;
dec = ?decimal digit?;
oct = ?octal digit?;
hex = ?hexadecimal digit?;
Examples:
0x5D:32, 0b0101:16, 5:64, +5:8, +0x5D:16, true, false.
.
Form false
is a shortcut for 0:1
, as well as true
is 1:1
.
If base
is omitted base-10 is assumed. The output format is
lways "0x", hex, {hex}
in an unsigned form.
typet =

Bitvector is a value, first of all, so it supports a common set of
a value interface: it can be stored, compared, it can be a key in
a dictionary, etc. Moreover, being a number it can be compared
with zero and applied to a common set of integer operations.

The symbol table maps strings to pointers to symbols. The use of pointers to Symbols allows polymorphic symbols in the symbol table. It also allows a given symbol to be 'morphed' to a different kind of symbol during parsing by replacing the Symbol pointer by a pointer to a new instance of a derived class of Symbol. Morphing requires that any persistent use of a Symbol in another object must be through an additional level of indirection, i.e. Symbol **.

25 August 1999
Disease Outbreak Reported
An outbreak of poliomyelitis has been reported from Kunduz province in Northern Afghanistan. Since early May, a total of 26 cases of children with paralysis have been reported as of today, of which 6 cases have already been confirmed as poliomyelitis through laboratory analysis. Fifteen of the 26 cases were reported from Kunduz town itself, with 11 cases from the districts surrounding Kunduz.
The outbreak was identified only because special disease reporting for suspected polio cases, including the capacity for laboratory confirmation, was established in May 1999 in the North as part of the nation-wide initiative to eradicate polio.
Since all immunization activities in Northern Afghanistan had nearly ceased in mid-1997 and are just now being re-established, the outbreak of poliomyelitis is not unexpected. To determine the full extent of the outbreak, all health facilities and NGOs providing health care in the North have been alerted to the outbreak and requested to report all suspected cases to the Ministry of Public Health (MoPH). A large-scale house-to-house immunization campaign, targeting more than 130,000 children aged < 5 years has been launched this week in the outbreak area as a collaborative effort between MoPH, WHO, UNICEF and NGOs.
Poliomyelitis is endemic in Afghanistan and the best way to prevent the disease is to immunize children with at least 3 doses of polio vaccine during their first year of life. The global strategy to eradicate polio includes supplementary country-wide campaigns called National Immunization Days (NIDs) when 2 drops of oral polio vaccine are given to all children under age 5 years, in 2 consecutive months. Country-wide NIDs were held in Afghanistan in May and June 1999 and are scheduled again for October and November. Unfortunately the outbreak in Kunduz started before the May NIDs.
For more information, visit the web site on the global eradication of poliomyelitis.

Learning Plan
Introduction
The idea of this learning plan is to create a plan of how I see the next 14-15 weeks of my life going and what I want to happen after the completion of this.
My Career Goal
I'm still employeed and taking a career break so I have a direct short term goal after comlpeting this course. My long-term goal is a bit cloudy I need to see if I really enjoy this line of work.
Short Term Goal- I want to be able to go back to my current employeer and utilize the skills and knowledge gained from this course to make advancements in what I could produce before this course. I was given assurances when they offered me a career break that I would have some pathways setup to use the skills and progress to the Dev side if that's what I wanted.
Long Term Goal- My long term goal is to have web devlopment in-grained in my career. I want to contiously gain new skills and build upon them. Honestly I'm not sure if I want a career that is 100% web development but I know I want it to be part of my career.
Strenghts, Limitations & Growth
My greatest strength comes from Passion. If I am passionate about something it almost becomes all consuming. The problem with that is I tend to veer off course sometimes. I will go down those rabbit holes and start looking at components that I do not need.
A limitation of mine is time managment. Im historically very poor at time management, all through Uni I was the caffine addict staying up 2 nights in a row to write a paper. Personally I feel like I have gotten better at time management since working in a presure environment. The reason I think this is because I hate disapointing people, so my concern is that now that the outcomes of this are solely going to impact myself. I don't want to fall back into an old behaviour. I go into this more in my learning and how I want to combat this. Also this learning plan creation came at the right time feel myself slipping.
How do I want to Grow
My main priority for soft skills growth is collaboration. Historically I have had really bad collaboration experinces stemming from UNI projects that have made really dislike collaboration. Some of which may have been partly my fault in not trying enough to colloberate.
Another one is confidence. Not Ego but confidence in speaking up and questioning a way of doing something.
How will I manage
How I plan my Days
I want to by consistient in my days. In some previous analyis I think my best time to work is in the morning fresh out of bed with the distractions of the outside world easily being tuned out.
My plan is to start every day at 7am and work through to 4pm. The first part of the day I want to commit to learning new things where I can focus better and retain information. The second part of the idealy is used to put that into practice. This is where I need to be actively doing something in order for me to focus.
When it goes it wrong {Hope for the best plan for the worst}
Where I see myself going wrong is in time boxing and meeting objectives. I tend to over complicate things and need to focus on the task at hand. One thing I have been doing in order to combat this is by writting down the objectives from the foundations handbook and having that visible on my screen at all times.
Asking for Help
I never ask for help, personally I view myself when I ask for help as not good enough. When I see others do that it never pops in to my head. I have a strict sort of internaly policy when it comes to asking for help. Ask once how that's fine don't ask again. My commimetent to asking for help, is to try first. I want to try and figure it out for myself in a timely manner. But after that I want to not be afraid to ask for help, be that my fellow cohort members or my facilator.
Looking at all the projects that people have been working on its evident that there is a lot of skilled people in this programe with skills leaps above my own. To not use there help through the slack channels would be a waste.
Joesph my foundations facilator is another resource I can use for questions and help. Also I hope I never have to do this but I can talk with him and if I have any challanges completing something there may be the option to have some sort of extension
Extensions are a short term soloution and the last thing I want to be doing is playing catchup
What are my expectations from my facilator
The facilator sessions are for Me
In my first catchup I was made aware that these sessions are for me and led my be. Very different to what I expected. For the next session I have I want to give it some structure, what was I struggling with and where he may be able to help out.
Expectations
My main expectation is feedback, I want to use it as time to talk through the project I am working on for that week. I will have issues things never go smoothly and I want to talk with him around how I can solve this or do better.
Also want to use the time as a place to have general discussions. The first one was good he re assured me about some dificulties I was having with CSS. There will be doubts and this is the time to express them.
Learning Plan Going into Bootcamp
What is your long term goal and/or career pathway?
I mentioned in one reflection how the goal I set at the start is not great in terms of the growth mindset. When learning about that it mentions about that this needs to be fueled by your hunger to learn not your need for approval. I mentioned in my last goal about wanting to bring what I learn back to my current employer. That is the part I want to change about my Short Term Goal.
Short Term- I want to be able to use and understand web development practices and feel confident implementing and planning any endeavor I take on.
Long Term Goal- My long Term goal is to be involved in producing something I am truly passionate about. Thinking this could be game design or personal projects. I want to move in to a line of work where I feel driven by the work I do as well as the people around me.
What do you think your biggest strengths and limitations will be in Bootcamp?
My biggest weakness was definitely time keeping. I think/hope that with the more structured bootcamp this will be easy to manage. I don't think anything has changed as such. I noticed that my shy reserved nature was tested a bit. Reached out to someone to talk about the carnival challenges and the same with the one on one active listening exercises. All though I was very nervous going into that chat.
What do you think your biggest non-technical challenge at bootcamp will be?
My biggest non-technical challenge will be I'm afraid of being wrong and embarrassing myself. I will definitely naturally shy away from any "how do you do that" sort of question to a group. This also limits my ability to function collaboratively.
What non-technical skills - human skills - would you like to see developed in yourself while at EDA?
Linked to the one above.  Whether if its no one cares if its dumb or people want judge you for it at all. I think its kinda linked to that idea of I don't want to damage my won ego if I'm not 100%.
Another one is around the mentality that it seems alot of programmers have around how they work. They do short focused bursts. Would really like to foster and build on that.
What are your expectations from the Bootcamp team?
My expectation is that the course is quite test and learn. This is how I like to learn you get given some sort of background information of what/how to do it then you apply to it a real scenario. If I get stuck I can talk to the group and facilitator if needed.
My main anti expectation is that we are not shown something and this is how this works now we move. If that's how its done that's fine but for me I will need to play around with it in my own time to truley understand it.
What are your expectations of yourself on Bootcamp?
My expectations is to learn new skills and put them into practice with a squad of like-minded people. I also want to develop some core skills and increase my 'employability' factor in that department.
To achieve this I kinda always want to feel out of my comfort range.
My commitment, which may sound odd I wnat to be as apporachable as possible. I am never going to listen to music or do anything like that during the course (not sure if allowed). Also when I get stuck I want to talk with other people if they are willing about how they are doing it. My idea here is to learn how what they did to do it at the point im stuck on. I don't want to copy pasta the entire function, possibly they can explain the rubbery ducky method of it and then I could engineer it from there.
A personal commitment that I will be doing is making sure Im in the perfect state of mind to learn. I have gotten enough sleep etc. Not like Uni where showing is the hard part.


Suez is located at the northern end of the Gulf of Suez and marks the southern end of the Suez Canal. It has been a commercial port since the 7th century although Suez itself was never much more than a village until the present day canal was opened. Today it is one of Egypt’s largest ports.
Yachts are usually met in the approaches by an agent's boat, who will offer his services, sometimes quite forcefully. It is therefore advisable to have made arrangements in advance with an agent, either in Hurghada, by phone/email or on VHF Channel 16. The agent will then meet the yacht on arrival.
The agent will obtain permission for the yacht to proceed directly to the Suez Yacht Club. The agent will also arrange for the officials to come to the club for clearance, or will deal himself with all other formalities, including Canal transit. The agent will also bring the Suez Canal pilot to the yacht club on the day of the transit.
See Agents for details of any Clearance agents.
Otherwise yachts should anchor in the waiting area in Port Ibrahim and contact Port Control on VHF Channel 16 for permission to go to Suez Yacht Club, which is located on the left-hand side of the Canal, just beyond the Canal Authority buildings.
Procedure for transiting the Suez Canal
To transit the Canal, the same formalities have to be gone through as those described for Port Said.
Although not compulsory, it is advisable to employ the services of an agent, as it is more difficult to complete the canal transit formalities alone than in Port Said. If using an agent, all fees should be agreed in advance and the agent should also be asked to specify exactly which fees and services are included. It is advisable to know your boat's tonnage, which for Suez measurements includes all covered structure about the deck (i.e. pilot house etc). The agents in Suez who appear to handle most cruising yachts are Prince of the Red Sea and Felix Maritime Agency.
The procedure for the transit is identical to the southward passage: the pilot will arrive early in the morning and the night will be spent at Ismailia where the pilot will board the following day and take the vessel to Port Said. Do not rely on the pilot knowing anything about piloting a yacht. Keep in 8-10m of water close to the buoys if the flow is against you and 15-18m if the flow is with you. You can gain well in excess of 1 knot doing so.
If a yacht gets into difficulties during the canal transit, contact your agent not the Canal Authority.
No yacht can transit the canal if a warship is passing through.
Be prepared for the "baksheesh" culture of the canal and carry plenty of small change US$.
Last updated October 2013.
Be warned there may be a con-man (elderly, white moustache) who lurking outside the yacht club in his car (silver/grey Daewoo Lanos) and who claims to work for Felix agency - he does not.

This would be relevant mostly for users implementing custom TypeSerializer
s for their state.
The old TypeSerializerConfigSnapshot
abstraction is now deprecated, and will be fully removed in the future
in favor of the new TypeSerializerSnapshot
. For details and guides on how to migrate, please see
[Migrating from deprecated serializer snapshot APIs before Flink 1.7]
(//ci.apache.org/projects/flink/flink-docs-master/dev/stream/state/custom_serialization.html#migration-from-deprecated-serializer-snapshot-apis-before-Flink-1.7).
There are a few APIs that have been changed since Flink 1.2. Most of the changes are documented in their specific documentations. The following is a consolidated list of API changes and links to details for migration when upgrading to Flink 1.3.
TypeSerializer
interface changesThis would be relevant mostly for users implementing custom TypeSerializer
s for their state.
Since Flink 1.3, two additional methods have been added that are related to serializer compatibility across savepoint restores. Please see Handling serializer upgrades and compatibility for further details on how to implement these methods.
ProcessFunction
is always a RichFunction
In Flink 1.2, ProcessFunction
and its rich variant RichProcessFunction
was introduced.
Since Flink 1.3, RichProcessFunction
was removed and ProcessFunction
is now always a RichFunction
with access to
the lifecycle methods and runtime context.
The CEP library in Flink 1.3 ships with a number of new features which have led to some changes in the API. Please visit the CEP Migration docs for details.
In Flink 1.3, to make sure that users can use their own custom logging framework, core Flink artifacts are now clean of specific logger dependencies.
Example and quickstart archetypes already have loggers specified and should not be affected.
For other custom projects, make sure to add logger dependencies. For example, in Maven’s pom.xml
, you can add:
As mentioned in the State documentation, Flink has two types of state: keyed and non-keyed state (also called operator state). Both types are available to both operators and user-defined functions. This document will guide you through the process of migrating your Flink 1.1 function code to Flink 1.2 and will present some important internal changes introduced in Flink 1.2 that concern the deprecation of the aligned window operators from Flink 1.1 (see Aligned Processing Time Window Operators).
The migration process will serve two goals:
allow your functions to take advantage of the new features introduced in Flink 1.2, such as rescaling,
make sure that your new Flink 1.2 job will be able to resume execution from a savepoint generated by its Flink 1.1 predecessor.
After following the steps in this guide, you will be able to migrate your running job from Flink 1.1 to Flink 1.2 simply by taking a savepoint with your Flink 1.1 job and giving it to your Flink 1.2 job as a starting point. This will allow the Flink 1.2 job to resume execution from where its Flink 1.1 predecessor left off.
As running examples for the remainder of this document we will use the CountMapper
and the BufferingSink
functions. The first is an example of a function with keyed state, while
the second has non-keyed state. The code for the aforementioned two functions in Flink 1.1 is presented below:
The CountMapper
is a RichFlatMapFunction
which assumes a grouped-by-key input stream of the form
(word, 1)
. The function keeps a counter for each incoming key (ValueState<Integer> counter
) and if
the number of occurrences of a certain word surpasses the user-provided threshold, a tuple is emitted
containing the word itself and the number of occurrences.
The BufferingSink
is a SinkFunction
that receives elements (potentially the output of the CountMapper
)
and buffers them until a certain user-specified threshold is reached, before emitting them to the final sink.
This is a common way to avoid many expensive calls to a database or an external storage system. To do the
buffering in a fault-tolerant manner, the buffered elements are kept in a list (bufferedElements
) which is
periodically checkpointed.
To leverage the new features of Flink 1.2, the code above should be modified to use the new state abstractions. After doing these changes, you will be able to change the parallelism of your job (scale up or down) and you are guaranteed that the new version of your job will start from where its predecessor left off.
Keyed State: Something to note before delving into the details of the migration process is that if your function has only keyed state, then the exact same code from Flink 1.1 also works for Flink 1.2 with full support for the new features and full backwards compatibility. Changes could be made just for better code organization, but this is just a matter of style.
With the above said, the rest of this section focuses on the non-keyed state.
The first modification is the transition from the old Checkpointed<T extends Serializable>
state interface
to the new ones. In Flink 1.2, a stateful function can implement either the more general CheckpointedFunction
interface, or the ListCheckpointed<T extends Serializable>
interface, which is semantically closer to the old
Checkpointed
one.
In both cases, the non-keyed state is expected to be a List
of serializable objects, independent from each other,
thus eligible for redistribution upon rescaling. In other words, these objects are the finest granularity at which
non-keyed state can be repartitioned. As an example, if with parallelism 1 the checkpointed state of the BufferingSink
contains elements (test1, 2)
and (test2, 2)
, when increasing the parallelism to 2, (test1, 2)
may end up in task 0,
while (test2, 2)
will go to task 1.
More details on the principles behind rescaling of both keyed state and non-keyed state can be found in the State documentation.
The ListCheckpointed
interface requires the implementation of two methods:
Their semantics are the same as their counterparts in the old Checkpointed
interface. The only difference
is that now snapshotState()
should return a list of objects to checkpoint, as stated earlier, and
restoreState
has to handle this list upon recovery. If the state is not re-partitionable, you can always
return a Collections.singletonList(MY_STATE)
in the snapshotState()
. The updated code for BufferingSink
is included below:
As shown in the code, the updated function also implements the CheckpointedRestoring
interface. This is for backwards
compatibility reasons and more details will be explained at the end of this section.
The CheckpointedFunction
interface requires again the implementation of two methods:
As in Flink 1.1, snapshotState()
is called whenever a checkpoint is performed, but now initializeState()
(which is
the counterpart of the restoreState()
) is called every time the user-defined function is initialized, rather than only
in the case that we are recovering from a failure. Given this, initializeState()
is not only the place where different
types of state are initialized, but also where state recovery logic is included. An implementation of the
CheckpointedFunction
interface for BufferingSink
is presented below.
The initializeState
takes as argument a FunctionInitializationContext
. This is used to initialize
the non-keyed state “container”. This is a container of type ListState
where the non-keyed state objects
are going to be stored upon checkpointing:
this.checkpointedState = context.getOperatorStateStore().getSerializableListState("buffered-elements");
After initializing the container, we use the isRestored()
method of the context to check if we are
recovering after a failure. If this is true
, i.e. we are recovering, the restore logic is applied.
As shown in the code of the modified BufferingSink
, this ListState
recovered during state
initialization is kept in a class variable for future use in snapshotState()
. There the ListState
is cleared
of all objects included by the previous checkpoint, and is then filled with the new ones we want to checkpoint.
As a side note, the keyed state can also be initialized in the initializeState()
method. This can be done
using the FunctionInitializationContext
given as argument, instead of the RuntimeContext
, which is the case
for Flink 1.1. If the CheckpointedFunction
interface was to be used in the CountMapper
example,
the old open()
method could be removed and the new snapshotState()
and initializeState()
methods
would look like this:
Notice that the snapshotState()
method is empty as Flink itself takes care of snapshotting managed keyed state
upon checkpointing.
So far we have seen how to modify our functions to take advantage of the new features introduced by Flink 1.2. The question that remains is “Can I make sure that my modified (Flink 1.2) job will start from where my already running job from Flink 1.1 stopped?”.
The answer is yes, and the way to do it is pretty straightforward. For the keyed state, you have to do nothing.
Flink will take care of restoring the state from Flink 1.1. For the non-keyed state, your new function has to
implement the CheckpointedRestoring
interface, as shown in the code above. This has a single method, the
familiar restoreState()
from the old Checkpointed
interface from Flink 1.1. As shown in the modified code of
the BufferingSink
, the restoreState()
method is identical to its predecessor.
In Flink 1.1, and only when operating on processing time with no specified evictor or trigger,
the command timeWindow()
on a keyed stream would instantiate a special type of WindowOperator
. This could be
either an AggregatingProcessingTimeWindowOperator
or an AccumulatingProcessingTimeWindowOperator
. Both of
these operators are referred to as aligned window operators as they assume their input elements arrive in
order. This is valid when operating in processing time, as elements get as timestamp the wall-clock time at
the moment they arrive at the window operator. These operators were restricted to using the memory state backend, and
had optimized data structures for storing the per-window elements which leveraged the in-order input element arrival.
In Flink 1.2, the aligned window operators are deprecated, and all windowing operations go through the generic
WindowOperator
. This migration requires no change in the code of your Flink 1.1 job, as Flink will transparently
read the state stored by the aligned window operators in your Flink 1.1 savepoint, translate it into a format
that is compatible with the generic WindowOperator
, and resume execution using the generic WindowOperator
.
Note Although deprecated, you can still use the aligned window operators
in Flink 1.2 through special WindowAssigners
introduced for exactly this purpose. These assigners are the
SlidingAlignedProcessingTimeWindows
and the TumblingAlignedProcessingTimeWindows
assigners, for sliding and tumbling
windows respectively. A Flink 1.2 job that uses aligned windowing has to be a new job, as there is no way to
resume execution from a Flink 1.1 savepoint while using these operators.
Attention The aligned window operators provide no rescaling capabilities and no backwards compatibility with Flink 1.1.
The code to use the aligned window operators in Flink 1.2 is presented below:

I am a fourth year computer science student at the University of Alberta. I have studied team software development, version control, and web design. Technologies I am proficient in include C, Java, Python, and SQL. I have completed several group projects with teams of five students,demonstrating I work well with others. One of my group members has noted that I work well under time pressure.
My goal is to find employment as a software developer or web developer in a dynamic progressive company. I am looking for an employer who will help me grow my skill set. In return, I will be punctual and work hard to learn and improve my skills. I enjoy self directed learning and discovering new things. I am comfortable working individually and as part of a team. My hobbies are longboarding, cycling, and playing board games. I am also interested in studying films.
I created a blogging/social network platform that aggregates posts from other social networks with a team of four other developers. The project is like a simpler version of diaspora.org. The project is RESTful and well documented.
I worked with a partner to write a C program that scans all the pages in memory and returns a list of blocks of memory that contain contiguous pages with the same permissions (read only, read-writeable, and inaccessible). We also wrote three driver programs to test and demonstrate the memory scanning functions.
I individually wrote a partially HTTP 1.1 compliant webserver in Python that serves static content.
I developed a partially HTTP 1.1 compliant web client that can GET and POST to a webserver.


Rapid Recap: Celtics lose heartbreaker to Clippers, 107-104 in OT
by Mike DynonRapid Recap is designed for the busiest of Celtics fans. Whether you can’t stay awake to read 10 paragraphs or your hangover is just too much, Rapid Recap tells the timeline of the game in only a minute or two.
If this was actually a Finals preview, we may not survive seven games like it.
The Celtics battled and led most of the night in Los Angeles, but a late rally by the Clippers enabled LA to escape with a 107-104 win in overtime.
Jayson Tatum had a game-high 30 points (12-24 FGs, 5-10 threes). Celts also got strong production from Daniel Theis (8 points, 14 boards, 6 assists, 3 steals) and Brad Wanamaker (14 points, 5 assists). However, Kemba Walker (4-17 FGs), Marcus Smart (1-11 threes) and Jaylen Brown (3-14 FGs) struggled all night with their shots.
The Clippers, who overcame 23 turnovers, were led by Lou Williams (27 points) and Paul George (25 points, 8 assists), but Patrick Beverley was everywhere with 14 points, 16 rebounds, 7 assists, 3 steals, and 2 blocks. PatBev and LouWill were the catalysts for the Clips’ late surge that stole the win.
Beverley came in shooting a brutal 18.9% from downtown for the season, but in the fourth and OT he – incredibly – made 4 of 5 from the arc.
Smart played despite mildly spraining his ankle two days ago, and the Clippers had their superstar duo of George and Kawhi Leonard on the court together for the first time ever.
The first half was forgettable, terrible basketball by both teams. The most notable Celtic was none other than Enes Kanter, who had 8 points and 5 rebounds in just 9 minutes.
By halftime, Boston was shooting just 36.7% and was 1-18 on threes, no one was in double figures, and Kemba Walker had as many turnovers as points (3 apiece), plus a frustration technical foul. Yet the Cs held a 42-40 lead because LA made only 37.5% and committed 13 turnovers leading to 12 Boston points.
Fortunately, both teams flipped the switch for the second half, especially Tatum, who hit four triples and had 14 points in the third.
The previously ice-cold Cs made 7 of 10 threes in the quarter and pulled ahead, 75-69, going to the fourth.
Kemba finally looked like himself when he drained a long three with 8:12 left, giving the Cs their largest lead to that point at 81-73. Two minutes later, he popped another to put Boston up 10. Then suddenly:
Celts got the lead back to 7 when Smart’s pass was luckily deflected by LA into the basket. But the Clippers responded with a 10-0 run led by Williams and Beverley, taking a 3-point lead. After a timeout, Tatum juked Paul George off his feet and banged home a clutch triple to tie the score with 13.1 remaining, leading to OT.
Tatum had 6 in the extra period, but George and Beverley combined for 10. Down three and needing a steal with seconds remaining, Smart made a sensational defensive play to give the Celtics one last chance,
Kemba tried to tie it at the buzzer, but Kawhi blocked his 3-point attempt to close it out.
Footnote: the refs clearly affected the outcome by missing a ridiculous number of obvious calls, and also hitting Brad Stevens with a technical in OT. We’ll have more to say about this in 5 Rational Thoughts on Thursday.

Method Detail
-
isP2PKH
public static boolean isP2PKH(Script script)
Returns true if this script is of the formDUP HASH160 <pubkey hash> EQUALVERIFY CHECKSIG
, ie, payment to an address like1VayNert3x1KzbpzMGt2qdqrAThiRovi8
. This form was originally intended for the case where you wish to send somebody money with a written code because their node is offline, but over time has become the standard way to make payments due to the short and recognizable base58 form addresses come in.
-
extractHashFromP2PKH
public static byte[] extractHashFromP2PKH(Script script)
Extract the pubkey hash from a P2PKH scriptPubKey. It's important that the script is in the correct form, so you will want to guard calls to this method withisP2PKH(Script)
.
-
isP2SH
public static boolean isP2SH(Script script)
Whether or not this is a scriptPubKey representing a P2SH output. In such outputs, the logic that controls reclamation is not actually in the output at all. Instead there's just a hash, and it's up to the spending input to provide a program matching that hash.
P2SH is described by BIP16.
-
extractHashFromP2SH
public static byte[] extractHashFromP2SH(Script script)
Extract the script hash from a P2SH scriptPubKey. It's important that the script is in the correct form, so you will want to guard calls to this method withisP2SH(Script)
.
-
isP2PK
public static boolean isP2PK(Script script)
Returns true if this script is of the form<pubkey> OP_CHECKSIG
. This form was originally intended for transactions where the peers talked to each other directly via TCP/IP, but has fallen out of favor with time due to that mode of operation being susceptible to man-in-the-middle attacks. It is still used in coinbase outputs and can be useful more exotic types of transaction, but today most payments are to addresses.
-
extractKeyFromP2PK
public static byte[] extractKeyFromP2PK(Script script)
Extract the pubkey from a P2SH scriptPubKey. It's important that the script is in the correct form, so you will want to guard calls to this method withisP2PK(Script)
.
-
isP2WH
public static boolean isP2WH(Script script)
Returns true if this script is of the formOP_0 <hash>
. This can either be a P2WPKH or P2WSH scriptPubKey. These two script types were introduced with segwit.
-
isP2WPKH
public static boolean isP2WPKH(Script script)
Returns true if this script is of the formOP_0 <hash>
and hash is 20 bytes long. This can only be a P2WPKH scriptPubKey. This script type was introduced with segwit.
-
isP2WSH
public static boolean isP2WSH(Script script)
Returns true if this script is of the formOP_0 <hash>
and hash is 32 bytes long. This can only be a P2WSH scriptPubKey. This script type was introduced with segwit.
-
extractHashFromP2WH
public static byte[] extractHashFromP2WH(Script script)
Extract the pubkey hash from a P2WPKH or the script hash from a P2WSH scriptPubKey. It's important that the script is in the correct form, so you will want to guard calls to this method withisP2WH(Script)
.
-
isSentToMultisig
public static boolean isSentToMultisig(Script script)

extractSenderPubKeyFromCltvPaymentChannel
public static byte[] extractSenderPubKeyFromCltvPaymentChannel(Script script)
Retrieves the public key of the sender from a LOCKTIMEVERIFY transaction. It's important that the script is in the correct form, so you will want to guard calls to this method withisSentToCltvPaymentChannel(Script)
.
-
extractRecipientPubKeyFromCltvPaymentChannel
public static byte[] extractRecipientPubKeyFromCltvPaymentChannel(Script script)
Retrieves the public key of the recipient from a LOCKTIMEVERIFY transaction. It's important that the script is in the correct form, so you will want to guard calls to this method withisSentToCltvPaymentChannel(Script)
.
