In the Treehouse is a container called the cardboard box.
The cardboard box is a closed container. The glass bottle is a transparent open container. The box is fixed in place and openable.
Check photographing:
if the noun is the camera, say "Sadly impossible." instead.
"[if the player is in Center Ring]A magician's booth stands in the corner, painted dark blue with glittering gold stars.[otherwise if the magician's booth is closed]A crack of light indicates the way back out to the center ring.[otherwise]The door stands open to the outside.[end if]".

A volume is a kind of value. 15.9 fl oz specifies a volume with parts ounces and tenths (optional, preamble optional).
A fluid container is a kind of container. A fluid container has a volume called a fluid capacity. A fluid container has a volume called current volume.
The fluid capacity of a fluid container is usually 12.0 fl oz. The current volume of a fluid container is usually 0.0 fl oz.
Liquid is a kind of value. The liquids are water, absinthe, and iced tea. A fluid container has a liquid.
Instead of examining a fluid container:
if the noun is empty,
say "You catch just a hint of [the liquid of the noun] at the bottom.";
otherwise
say "[The noun] contains [current volume of the noun in rough terms] of [liquid of the noun]."
To say (amount - a volume) in rough terms:
if the amount is less than 0.5 fl oz:
say "a swallow or two";
otherwise if tenths part of amount is greater than 3 and tenths part of amount is less than 7:
let estimate be ounces part of amount;
say "[estimate in words] or [estimate plus 1 in words] fluid ounces";
otherwise:
if tenths part of amount is greater than 6, increase amount by 1.0 fl oz;
say "about [ounces part of amount in words] fluid ounce[s]".
Before printing the name of a fluid container (called the target) while not drinking or pouring:
if the target is empty:
say "empty ";
otherwise:
do nothing.
After printing the name of a fluid container (called the target) while not examining or pouring:
unless the target is empty:
say " of [liquid of the target]";
omit contents in listing.
Instead of inserting something into a fluid container:
say "[The second noun] has too narrow a mouth to accept anything but liquids."
Definition: a fluid container is empty if the current volume of it is 0.0 fl oz. Definition: a fluid container is full if the current volume of it is the fluid capacity of it.
Understand "drink from [fluid container]" as drinking.
Instead of drinking a fluid container:
if the noun is empty:
say "There is no more [liquid of the noun] within." instead;
otherwise:
decrease the current volume of the noun by 0.2 fl oz;
if the current volume of the noun is less than 0.0 fl oz, now the current volume of the noun is 0.0 fl oz;
say "You take a sip of [the liquid of the noun][if the noun is empty], leaving [the noun] empty[end if]."
Part 2 - Filling
Understand the command "fill" as something new.
Understand "fill [fluid container] with/from [full liquid source]" as filling it with. Understand "fill [fluid container] with/from [fluid container]" as filling it with.
Understand "fill [something] with/from [something]" as filling it with.
Filling it with is an action applying to two things. Carry out filling it with: try pouring the second noun into the noun instead.
Understand "pour [fluid container] in/into/on/onto [fluid container]" as pouring it into. Understand "empty [fluid container] into [fluid container]" as pouring it into.
Understand "pour [something] in/into/on/onto [something]" as pouring it into. Understand "empty [something] into [something]" as pouring it into.
Pouring it into is an action applying to two things.
Check pouring it into:
if the noun is not a fluid container, say "You can't pour [the noun]."  instead;
if the noun is the second noun, say "You can hardly pour [the noun] into itself." instead;
if the liquid of the noun is not the liquid of the second noun:
if the second noun is empty, now the liquid of the second noun is the liquid of the noun;
otherwise say "Mixing [the liquid of the noun] with [the liquid of the second noun] would give unsavory results." instead;
if the noun is empty, say "No more [liquid of the noun] remains in [the noun]." instead;
if the second noun is full, say "[The second noun] cannot contain any more than it already holds." instead.
Carry out pouring it into:
let available capacity be the fluid capacity of the second noun minus the current volume of the second noun;
if the available capacity is greater than the current volume of the noun, now the available capacity is the current volume of the noun;
increase the current volume of the second noun by available capacity;
decrease the current volume of the noun by available capacity.
Report pouring it into:
say "[if the noun is empty][The noun] is now empty;[otherwise][The noun] now contains [current volume of the noun in rough terms] of [liquid of the noun]; [end if]";
say "[the second noun] contains [current volume of the second noun in rough terms] of [liquid of the second noun][if the second noun is full], and is now full[end if]."
Understand the liquid property as describing a fluid container. Understand "of" as a fluid container.
A liquid source is a kind of fluid container. A liquid source has a liquid. A liquid source is usually scenery. The fluid capacity of a liquid source is usually 3276.7 fl oz. The current volume of a liquid source is usually 3276.7 fl oz. Instead of examining a liquid source: say "[The noun] is full of [liquid of the noun]."
Carry out pouring a liquid source into something: now the current volume of the noun is 3276.7 fl oz.
After pouring a liquid source into a fluid container:
say "You fill [the second noun] up with [liquid of the noun] from [the noun]."
Instead of pouring a fluid container into a liquid source:
if the noun is empty, say "[The noun] is already empty." instead;
now the current volume of the noun is 0.0 fl oz;
say "You dump out [the noun] into [the second noun]."
Swimming is an action applying to nothing. Understand "swim" or "dive" as swimming.
Instead of swimming in the presence of a liquid source:
say "You don't feel like a dip just now."
Before inserting something into a liquid source: say "[The noun] would get lost and never be seen again." instead.
Part 3 - Scenario
The Lakeside is a room. The Lakeside swing is an enterable supporter in the Lakeside. "Here you are by the lake, enjoying a summery view."
The glass is a fluid container carried by the player. The liquid of the glass is absinthe. The current volume of the glass is 0.8 fl oz.
The pitcher is a fluid container in the Lakeside. The fluid capacity of the pitcher is 32.0 fl oz. The current volume of the pitcher is 20.0 fl oz. The liquid of the pitcher is absinthe.
The lake is a liquid source. It is in the Lakeside.
The player wears a bathing outfit. The description of the bathing outfit is "Stylishly striped in blue and white, and daringly cut to reveal almost all of your calves, and quite a bit of upper arm, as well. You had a moral struggle, purchasing it; but mercifully the lakeshore is sufficiently secluded that no one can see you in this immodest apparel."
Instead of taking off the outfit: say "What odd ideas come into your head sometimes!"
Test me with "fill glass / empty absinthe into lake / fill glass / swim / drink lake / drink / x water / x lake".

Rennes put €50m price-tag on Eduardo Camavinga?
Rennes will allegedly demand €50m (£42.95m) if any clubs express an interest in Eduardo Camavinga.
by Darren PlantDespite having only turned 17 years of age earlier this month, the midfielder has established himself as a first-team regular at the Ligue 1 outfit.
However, the prospect's emergence has inevitably led to widespread attention in his signature, with Barcelona and Real Madrid said to be among the clubs monitoring the situation.
According to L'Equipe, Rennes have placed a firm valuation on the teenager's services should they receive any offers during the January window.
While Camavinga still has over two-and-a-half years remaining on his contract, there is seemingly an acceptance from Rennes that they must be realistic regarding any potential sale.
The France Under-21 international has made 16 appearances in all competitions this season.

Trainee pilot forced to keep Kenyan plane airborne after wheel falls off
by CHARLES LWANGAIn Summary
- Kenya School of Flying trainee pilot forced to keep plane airborne for two-hours to burn fuel to avoid explosion before crash landing at the Malindi International Airport.
- Malindi airport manager says the aircraft and the runway was damaged.
- Trainee pilot and instructor taken to hospital for psychological counselling due to trauma.
A light aircraft was forced to fly for two-hours to exhaust its fuel before crash landing at the Malindi International Airport at Kenya's coast on Monday.
Malindi airport manager Mohammed Karama said the Cessna 152 aircraft, belonging to the Kenya School of Flying, lost one of its wheels mid-air and had to fly for two hours to avoid explosion when landing.
“The control tower noticed that its fore wheel was missing while mid-air and the pilot was advised to fly for two hours due to security reasons,” he said.
Mr Karama said that the aircraft had only one occupant, a male pilot who is undertaking aviation studies.
“He crash-landed but he did not suffer injuries, although he was taken to the hospital together with his tutor who was directing him while mid-air for psychological counselling due to trauma,” he said.

Mr Karama said a security team, fire brigadiers and medical personnel’s from Tawfique hospital had already arrived at the airport when the aircraft was crash landing to avert any calamity.
However, he said the aircraft and the runway was damaged.
“The cause of the accident will be established by aviation investigators,” he said, adding that the incident happened when the airspace was not busy and it therefore did not disrupt the normal operation.
Incidents of the aircraft used by the Kenya School of Flying crash landing in the area are not new to locals, who have called on the management to service the planes to avoid disaster.
In November last year, a pilot was injured after a light aircraft failed to climb high enough during take-off and crashed into an electric post near a house in Furunzi, Malindi.
In September 2016, a flight instructor and her student from Kenya School of Flying survived a crash at Malanga Primary school after their training aircraft developed mechanical problems.

The gaming industry is predicted to be worth more than $115bn by the end of 2018, rising to a value of almost $138.5bn in 2021, according to Statista. Its vast and snowballing success as an industry is down to its developers' enthusiasm for embracing the latest technologies and innovations.
In fact, often, the gaming industry has paved the way for other industries, for example, its use of virtual reality.
Currently, AI is the word on everyones' lips, with the potential to turn the whole industry on its head.
It would be difficult to single out any technology, but I certainly can zoom into a single area, which is connectivity.

This is an account of my first, and so far only, mushroom experience. Prior to this experience, I had been worried about my social addiction to marijuana, as not a day went by when I didn't yearn to get stoned.
Anyway, after discussing mushrooms with a friend who had previously tried them, I said that I was curious to try them sometime in the future. A few days later, I got a call from that friend who told me that we could try them within a day. After much indecision, I agreed, and headed off to his place, with the company of a few friends.
That night, I ended up eating a gram, as did my friend and two others. I only really knew 2 of the other three trippers, and I hated one of them.
I guess it was about 15 minutes after eating that I suddenly realized that I was feeling a bit weird. My feet went numb and I began to feel like I was a conduit for spiritual energy. I had to move around a lot, because the spiritual energy shifted, and I wanted to stay in the flow. I also began to see swirling geometrical shapes on the floor. One of my friends, who was sober, asked me what I was looking at, and if I was hallucinating. Although it seems odd to me now, I didnt think that I was hallucinating, that the patterns had always been there, I had just never noticed them.
Shortly afterwards, I had begun to feel energetic, and went downstairs to play the piano. After a short discussion with the piano, I proceeded to play, and the music sounded so . . . euphoric. I felt the sensation that someone was laughing just over my right shoulder, although no one was there. I looked over my right shoulder and saw three spiritual entities, whom I assume to be manifestations of the universal conciousness (god, if you insist). Oddly, I didnt pay them any attention, didn't attempt communication (I'm still kicking myself), and continued to play the piano.
After an incredible surge of energy which blasted me back to reality some 2 hours and thousands of anecdotes later, I had a moment of self reflection. During the trip I lost my claustrophobia, lost my fear of spirits, lost my fear of dark, and lost my flinching reflex. (Usually I flinch when someone snaps their fingers two blocks away, but during the trip I was immune to external stimulus.)
Now here comes my moment of pride: After the trip I no longer even think about marijuana. It went from the center of my life to just some waste of time that occasions me rarely. It is now almost 3 months later and I have only been stoned twice, and only because I am apparently really fun to be stoned with, so my friends talked me into it.
Aftermath: More spiritual
Lost several addictions (computer games included)
Feel more confident, artistic, and creative.
Overall View on This particular drug: It can be good or bad, depending on how you use it (recreation vs. spiritual)

Explain to a non-tech friend
In the javascript language, describe all the use cases for each of:
parentheses ( )
Parentheses are used in several different ways in javaScript. They are used when defining functions, they surround any arguments the function will take. These 'arguments' are inputs which will be transformed in some way by the function.
Another way they are used is when calling functions. Basically this means using or invoking the instructions you have written in the function. So if you have a function called 'multiply', you would called it with multiply(), passing in any arguments within the parentheses, in this case a number to be multiplied.
See also the section on braces below for usage of parentheses in loops & conditional statements.
brackets [ ]
Square brackets are used to contain arrays. You can define an empty array like so.. var newArray = []. Or you could define an array containing elements with var newArray = [23, 50, "Hi there"]
Another place where square brackets are used is when accessing object properties with bracket notation. If I have an object called 'bedroom' which has a property of 'bed', then I can access this bed property by bedroom["bed"]
braces { }
Braces or curly braces are used in functions to contain the code which is the body of a function. They also can define objects eg. var myObject = {"hair": "grey"}
They are also used to contain the body of loops, such as 'for' loops or 'while' loops. And also 'if' statements/conditionals. Typically a if statement is written like so. if (newArray > 0) {
do something
}
In this instance, the parentheses surround the condition which if it evaluates to true, then the code in the curly braces will execute.
single quotes ' '
Single quotes can be used to surround strings or array elements.
double quotes " "
Double quotes can be used to surround strings or array elements and in some cases are preferable to single quotes. If the string you are surrounding itself contains single quotes, for example the string "I said to her 'Catch ya later', then I left", if these are surrounded by single quotes it can mean that the program doesn't get interpreted properly and the interpreter will not understand which part is a string.

I enjoy the flexibilty on peoples learning experience as all people learn differently. in my personal experiance i did not recieve this kind of learning during school so I am very excited to see what the boot camp has in store for this.
Shereefs insight on the course is very observational. i enjoyed his explanation on how people on different levels with coding can all do well on the same course. it was also good to have that put into perspective with the fact that coding is a long journey and the people that seem to be miles ahead still have a long way to go compared to the teachers and other long standing developers.
I look forward to learning along side other people and i think this culture will help me to grow with knowledge of code and the ability to work efficiently and well in a group.
My EDA expectations have not changed to much as i have been informed from the get go from the interview process and phone calls. and also from word of mouth from prior students. Although i am becoming more informed as I go andit is exciting.
I am both very nervous and very excited to participate in the environment as i wont know how well i will perform untill i am in the thick of it.


This is one of the beauties my partner Jess and I came up with on our very first day. Using very basic HTML, we made lists upon lists, and then added images and links. Efficient, if a little early 90s.
Still a little more basic HTML, but now you can find out a little about this terrifying household beast.
Who doesn't like to go on vacation? The question is where though. Using some more advanced CSS and html, hopefully this resort's webpage is sure to lure you to paradise. They can try anyway!
Remember all those times your high school teacher wagged a stern finger against copying Wikipedia? Epicodus goes against the grain once again, "Hey, you can copy that wiki, and you better make it as exact as possible!" In this project, we attempted just that with the powers of Bootstrap and a whole lot of our own CSS.

SICOPOLIS (SImulation COde for POLythermal Ice-sheets) is a 3-D thermo-mechanical finite difference ice-sheet-shelf model 29. On land, the model utilises a hybrid combination of the SIA and the SSA (including basal drag) as described in ref. 30, following ref. 62.
Basal sliding is described by a Weertman-type power law with a cubic dependence on basal shear stress, allowing sub-melt sliding following ref. 64. The distribution of basal sliding coefficients used in all runs is obtained from a calibration run using an iterative technique 17, 30.
For the surface mass balance, precipitation is converted to snow accumulation with a linear function of surface temperatures 65. Surface melting is parameterised by a PDD method 66, 67. PDD factors are 8 and 3 mm day −1 °C −1 for ice and snow, respectively.
Ice-shelf basal melting is computed using Eq. ( 4) 68, with n = 2. For the control simulations, a tuning melt factor of Fmelt = 0.2 m s −1 K −1 is applied at the floating side of some grounding lines (northwest of Ronne Ice Shelf and south of Amery Ice shelf) to better represent their modern positions. At each time step, the calving front is iteratively checked for grid points with a thickness below 50 m, which are calved out, until no more calving occurs.


Varnish can be a tricky beast to debug, having potentially thousands of threads crowding into a few data structures makes for interesting core dumps.
Actually, let me rephrase that without irony: You tire of the "no, not thread 438 either, lets look at 439 then..." routine really fast.
So if you run into a bug, it is important that you spend a little bit of time collecting the right information, to help us fix the bug.
The most valuable information you can give us, is always how to trigger and reproduce the problem. If you can tell us that, we rarely need anything else to solve it. The caveat being, that we do not have a way to simulate high levels of real-life web-traffic, so telling us to "have 10.000 clients hit at once" does not really allow us to reproduce.
Roughly we have three clases of bugs with Varnish, and the information we need to debug them depends on the kind of bug.
Plain and simple: boom
Varnish is split over two processes, the manager and the child. The child does all the work, and the manager hangs around to resurect it, if it crashes.
Therefore, the first thing to do if you see a varnish crash, is to examine your syslogs, to see if it has happened before. (One site is rumoured to have had varnish restarting every 10 minutes and still provide better service than their CMS system.)
When it crashes, if at all possible, Varnish will spew out a crash dump that looks something like:
Child (32619) died signal=6 (core dumped)
Child (32619) Panic message: Assert error in ccf_panic(), cache_cli.c line 153:
Condition(!strcmp("", "You asked for it")) not true.
errno = 9 (Bad file descriptor)
thread = (cache-main)
ident = FreeBSD,9.0-CURRENT,amd64,-sfile,-hcritbit,kqueue
Backtrace:
0x42bce1: pan_ic+171
0x4196af: ccf_panic+4f
0x8006b3ef2: _end+80013339a
0x8006b4307: _end+8001337af
0x8006b8b76: _end+80013801e
0x8006b8d84: _end+80013822c
0x8006b51c1: _end+800134669
0x4193f6: CLI_Run+86
0x429f8b: child_main+14b
0x43ef68: start_child+3f8
[...]
If you can get that information to us, we are usually able to see exactly where things went haywire, and that speeds up bugfixing a lot.
There will be a lot more information than this, and before sending it all to us, you should obscure any sensitive/secret data/cookies/passwords/ip# etc. Please make sure to keep context when you do so, ie: do not change all the IP# to "X.X.X.X", but change each IP# to something unique, otherwise we are likely to be more confused than informed.
The most important line is the "Panic Message", which comes in two general forms:
This is a place where we can conceive ending up, and have not (yet) written the padded-box error handling code for.
The most likely cause here, is that you need a larger workspace for HTTP headers and Cookies. (XXX: which params to tweak)
Please try that before reporting a bug.
In your syslog it may all be joined into one single line, but if you can reproduce the crash, do so while running varnishd manually:
varnishd -d <your other arguments> |& tee /tmp/_catch_bug
That will get you the entire panic message into a file.
(Remember to type start to launch the worker process, that is not automatic when -d is used.)
This kind of bug is nasty to debug, because usually people tend to kill the process and send us an email saying "Varnish hung, I restarted it" which gives us only about 1.01 bit of usable debug information to work with.
What we need here is all the information can you squeeze out of your operating system before you kill the Varnish process.
One of the most valuable bits of information, is if all Varnish' threads are waiting for something or if one of them is spinning furiously on some futile condition.
Commands like top -H or ps -Haxlw or ps -efH should be able to figure that out.
If one or more threads are spinning, use strace or ktrace or truss (or whatever else your OS provides) to get a trace of which system calls the varnish process issues. Be aware that this may generate a lot of very repetitive data, usually one second worth is more than enough.
Also, run varnishlog for a second, and collect the output for us, and if varnishstat shows any activity, capture that also.
When you have done this, kill the Varnish child process, and let the master process restart it. Remember to tell us if that does or does not work. If it does not, kill all Varnish processes, and start from scratch. If that does not work either, tell us, that means that we have wedged your kernel.
These are the easy bugs: usually all we need from you is the relevant transactions recorded with varnishlog and your explanation of what is wrong about what Varnish does.
Be aware, that often Varnish does exactly what you asked it to, rather than what you intended it to do, so it sounds like a bug that would have tripped up everybody else, take a moment to read though your VCL and see if it really does what you think.
You can also try setting the vcl_trace parameter, that will generate log records with like and char number for each statement executed in your VCL program.

BetterRandom is a library that helps you get the best performance and the best pseudorandomness from your pseudorandom-number generators (PRNGs) and their seed sources. With it, you can:
SplittableRandom
, with its improved speed and randomness-test performance, as a
java.util.Random
so that methods like
Collections.shuffle(List<>,Random)
can use it.
ThreadLocalRandom
but still safe to pass between threads.Supplier<Random>
to create a Random
that's thread-local, but can be accessed just
like any other Random
.AesCounterRandom
, a PRNG that's as secure as AES but much faster than SecureRandom
.java.util.Random
, because they're subclasses of
java.util.Random
.BaseRandom
.RandomSeederThread
class does this and can
use any of the following seed sources:
/dev/random
SecureRandom
DefaultSeedGenerator
.SeedGenerator
interface.Yeah, but it's not random enough for you. Monte Carlo simulations have been known to
give misleading results because of low-quality
PRNGs, and the implementation in java.util.Random
is low-quality for two reasons:
long
and double
values are impossible to
generate. This means "uniform distributions" aren't uniform.Many standard tests of randomness amount to Monte Carlo simulations. And since widespread pseudorandom number generators (PRNGs) pass most but not all such tests in standard suites such as BigCrush and Dieharder, this suggests that any Monte Carlo simulation may turn out to be a test of randomness, and to give misleading or untrustworthy results because of an unfortunate choice of PRNG. There are two ways to minimize this risk, both of which BetterRandom can help with:
Don't take chances on randomness -- get it right with BetterRandom.
At both links, choose BetterRandom if using JDK 8+ and/or Android API 24+ at both compile-time and runtime. Otherwise, choose BetterRandom-Java7.

BetterRandom has 2 versions, one for Java 7 -- including Android API levels below 24 -- and one for Java 8 and newer.
Beginning with version 3.1.2, continuous integration has been moved to Azure Pipelines and includes the following environments:
OpenJDK 8, 11 and 12 on Ubuntu and Windows are Azul Zulu builds. OpenJ9 is AdoptOpenJDK. For OpenJDK on OSX, the preinstalled builds on Microsoft's OSX system images are used; their provenance is unclear, but they are to be replaced with Azul Zulu in April 2019.
For versions up to 3.1.1, continuous integration took place in the following environments:
CI on BSD or Android isn't likely any time soon, since no free providers of BSD CI seem to be integrated with GitHub, and there seems to be no actively-maintained Android-app wrapper for TestNG suites. However, Android API levels 24 and up (required as both source and target) should work.
This branch is mainly intended to support Android API levels 19 through 23; support for other environments is best-efforts. Active development on this branch is likely to end once 80% of Android devices have API level 24 or newer, as measured by Google, and Java 18.09 LTS has been released (which will mean Java 7 will be two major long-term-support versions out of date).
Continuous integration takes place in OpenJDK 7 on Linux. Up to and including version 3.1.1, this was done on Travis CI; beginning with 3.1.2, Azure Pipelines will be used.
BetterRandom provides several pseudorandom number generators that are intended as drop-in
replacements for java.util.Random
.
betterrandom.prng
Reproducible: The getSeed()
function retrieves a seed that can be passed into the constructor to
create another PRNG giving the same output. If any random numbers have been generated since
construction or a call to setSeed(byte[])
, this may rewind the state to before that happened.
Serializable: All these PRNGs can be serialized and deserialized, copying their full internal state.
setSeed(byte[])
: Reseed even if more than a long
is needed to do so.
** Use getNewSeedLength()
to get the recommended seed size.
entropyBits()
: Find out when the PRNG has output more random data than it has been seeded with,
and thus could benefit from being reseeded. Even when the PRNG is reseeded repeatedly without
being used, the entropy count won't ever go above the size of the PRNG's internal state.
withProbability(double)
: Get a boolean with any probability of being true, not just 50/50, and
the PRNG will still know you're only spending 1 bit of entropy. (Technically it may be less
than 1 bit, but we don't implement
fractional-bit counting yet.)
Lockless nextGaussian()
.
doubles
, ints
and longs
will return parallel streams whenever possible, whereas their
implementations in Random
always return sequential streams.
gaussians()
and gaussians(long streamSize)
: Get an endless or finite stream of
normally-distributed doubles.
setSeederThread(RandomSeederThread)
: Reseeds the PRNG whenever its entropy is spent, but only
as long as a seed generator can keep up. See below.
These classes use java8.util.SplittableRandom
instances to implement the methods of Random
,
despite that the two classes are unrelated and have slightly different method signatures. Several
adapters are available:
SingleThreadSplittableRandomAdapter
: Simple and fast, but not thread-safe.SplittableRandomAdapter
: Backed by a ThreadLocal<SplittableRandom>
, whose instances of
SplittableRandom
are all split from a single master.ReseedingSplittableRandomAdapter
: Also backed by a ThreadLocal<SplittableRandom>
, this
registers each thread's SplittableRandom
instance with a RandomSeederThread
(see below). This
is probably the best PRNG implementation that allows concurrent access from multiple threads.| Class | Seed size (bytes) | Period (bits) | Speed | Speed with RandomSeederThread | Effect of setSeed(long) |
getSeed() rewinds? |

| Cmwc4096Random | 16384 | 2131104 | Medium | Very slow | Not supported | Yes | George Marsaglia |

| Pcg128Random | 16 | 2126 | Medium | Medium | Replaces existing seed | Yes | M. E. O'Neill |
*Seed sizes above 32 for AesCounterRandom require jurisdiction policy files that allow 192- and 256-bit AES seeds.
**Can be reseeded independently on each thread, affecting only that thread.
†Use specialized subclass ReseedingSplittableRandomAdapter.
Retrieving the internal state of an AesCounterRandom
instance from its output is considered
equivalent to breaking the AES cipher. Thus, this class should be able to replace SecureRandom
in
many applications, such as generating session keys or erasing files on a magnetic disk or tape.
AesCounterRandom only generates a permutation of the space of 128-bit integers, so if it is used
to generate about 264 128-bit strings without reseeding, its statistical properties will
begin to differ from those of /dev/random
in that it won't have
generated the same string twice. This could be
prevented by using a hash function rather than a reversible cipher, but the hash functions in
standard JVMs are less cryptographically secure than AES and won't run as fast on hardware featuring
AES-NI.
SeedGenerator
A SeedGenerator
produces seeds for PRNGs. All the provided implementations are singletons, because
the seed sources cannot be parallelized. They include:
DevRandomSeedGenerator.DEV_RANDOM_SEED_GENERATOR
: Works only on Unix-like systems; reads seeds
from /dev/random
.RandomDotOrgSeedGenerator.RANDOM_DOT_ORG_SEED_GENERATOR
: Connects to
random.org to retrieve random numbers over HTTPS.
Random.org collects randomness from atmospheric noise using 9 radios, located at undisclosed
addresses in Dublin and Copenhagen and tuned to undisclosed AM/FM frequencies. (The secrecy is
intended to help prevent tampering with the output using a well-placed radio transmitter, and the
use of AM/FM helps ensure that any such tampering would cause illegal interference with broadcasts
and quickly attract regulatory attention.) Uses the legacy API by default, but can be configured
to use the JSON-RPC API.
RandomDotOrgSeedGenerator.RATE_LIMITED_ON_FAIL
: Avoids spamming Random.org or your router, by
instantly reporting failure for 10 seconds after every I/O or HTTP error.SecureRandomSeedGenerator.SECURE_RANDOM_SEED_GENERATOR
: Uses
java.security.SecureRandom.generateSeed
. On Oracle and OpenJDK, this in turn uses
sun.security.provider.SeedGenerator
; when /dev/random
isn't available, that in turn uses the
timing of newly-launched threads as a source of randomness, relying on the unpredictable
interactions between different configurations of hardware and software and their workloads.DefaultSeedGenerator.DEFAULT_SEED_GENERATOR
: Uses the best of the above three that is currently
available.This is a daemon thread that loops over all the Random
instances registered with it and reseeds
them. Those that implement EntropyCountingRandom
are skipped when they still have entropy left
from a previous seeding. Example usage:
// Obtain the seeder thread for this seed generator; launch it if it's not already running.
RandomSeederThread seederThread = RandomSeederThread.getInstance(DEFAULT_SEED_GENERATOR);
// Thread is now running, but is asleep if no PRNGs have already been added to it.
// Begin including myRandom in the loop, and wake up the thread.
seederThread.add(myRandom);
// Manually trigger reseeding ASAP (myRandom must be added first)
if (myRandom instanceof EntropyCountingRandom) {
seederThread.asyncReseed(myRandom);
}
// Adding the same PRNG a second time has no effect
seederThread.add(myRandom);
Many of these scripts require the environment variable JAVA8=true
when using JDK 8.

FILM TITLE: BEAUTIFUL DREAMERS DIRECTOR: JOHN HARRISON COUNTRY: CANADA ( 1992 ) CAST: Colin Feore, Wendel Meldrum, Sheila McCarthy, Colin Fox, Rip Torn as Walt Whitman. MUSIC: LAWRENCE SHRAGGE SUPER FEATURES: Super story.
AWAKENINGS, with Robin Williams, gave us a side to a part of the world that is a bit on the sordid side, and almost always not helpful to the few that are a bit on the needy side. Where AWAKENINGS leaves us feeling sad, and unable to live with the consequences, BEAUTIFUL DREAMERS comes through. And it comes through showing that there are many ways to deal with the human condition, love being the single most important factor of all....and experimenting with elements which science almost never considers being the other.
All in all, the late nineteenth century is shown as the century where medicine begins to study its more sordid side for curing people by cutting more into them, instead of the option of trying different things and processes which have been used for many ages, by many different cultures. And the film begins with just that. The disabled, physically and otherwise, are the test rats upon whose bodies all forms of experiments are conducted, and at a famous conference a certain R. M. Buck goes to detail his own ideas, only to quit before he gets started because almost all the serious doctors are veritable doctor Frankenstein's, rather than healers. And in the audience is an elder gentleman with a large beard and temperament, who makes fun of a few of the experiments, much to the chagrin of the audience of doctors. And this elder man as it turns out is the free thinker Walt Whitman, in a time when this type of thinking is not considered to be in vogue, although he seems to do very well.
Mr. Buck's wife, who is having doubts about her husband's ways, as is the institution that employs him, is also planning on ending a relationship, because she herself does not understand what is going on, and how the free thinking poet is actually interfering with her relationship. But in her solitude and despair it is the few words of the poet which bring her around, to realize that what is happening is more than meet the eye, and in actuality, it is the correct and best thing....and the humane thing to do. Amidst all this, is the poet who refuses to be pegged down to a definition, and comes up with a line or two at a party which alienates the crowd somewhat.....certainly not the classical style of words they wanted to hear.
As time goes by, and with the suggestion of the poet, the doctor begins to lead his motley crew into exercises of fun, and socializing with the affluent which in the end leads to success and the fall of the priest and mayor whose attitudes are more conformist than they are positive and spiritually guided. Of all the films I have seen this year, few stand out as true victories of the human spirit, and it takes one story of a free thinker, or two, to bring out a sense of beauty in the human spirit which is not always found in many films. The winners are the disabled, that are now considered better people instead of test animals. And unlike the film AWAKENINGS, this film makes other doctors turn their minds to what is happening, and how it is going to be.
All in all, it also shows the desire that a few countries have for finding new cures for the most disabling things, rather than the strict medical style that tends to be de-humanizing. In England, there still are experiments being carried out which also involve arts and totally different ways of dealing with society's disabilities. R. M. Buck's ways was but one of them.
With an excellent cast, and an ability to show something which is poignant and at times unpleasant, this film is truly beautiful and stands out as one of the few.

DOTA-v1.5 contains 0.4 million annotated object instances within 16 categories, which is an updated version of DOTA-v1.0. Both of them use the same aerial images but DOTA-v1.5 has revised and updated the annotation of objects, where many small object instances about or below 10 pixels that were missed in DOTA-v1.0 have been additionally annotated. The categories of DOTA-v1.5 is also extended. Concretely, the category of container crane is added.
In consistent with DOTA-v.1.0, the images in DOTA-v1.5 are mainly collected from the Google Earth, satellite JL-1, and satellite GF-2 of the China Centre for Resources Satellite Data and Application. Use of the images from Google Earth must respect the corresponding terms of use: "Google Earth" terms of use. All images and their associated annotations in DOTA-v1.5 can be used for academic purposes only, but any commercial use is prohibited.
The object categories in DOTA-v1.5 include: plane, ship, storage tank, baseball diamond, tennis court, basketball court, ground track field, harbor, bridge, small vehicle, large vehicle, helicopter, roundabout, soccer ball field, swimming pool and container crane.
In the dataset, each instance's location is annotated by a quadrilateral bounding boxes, which can be denoted as "x 1, y 1, x 2, y 2, x 3, y 3, x 4, y 4" where (x i, y i) denotes the positions of the oriented bounding boxes' vertices in the image. The vertices are arranged in a clockwise order. The following is the Visualization of adopted annotation method. The yellow point represents the starting point. which refers to: (a) top left corner of a plane, (b) top left corner of a large vehicle diamond, (c) the center of sector-shaped baseball.
Except the annotation of location, category label is assigned for each instance, which comes from one of the above 15 selected categories, and meanwhile a difficult label is provided which indicates whether the instance is difficult to be detected(1 for difficult, 0 for not difficult). Annotations for an image are saved in a text file with the same file name. At the first line, 'imagesource'(from GoogleEarth, GF-2 or JL-1) is given. At the second line, ’gsd’(ground sample distance, the physical size of one image pixel, in meters) is given. Note if the 'gsd' is missing, it is annotated to be 'null'. From third line to last line in annotation text file, annotation for each instance is given. The annotation format is:
We have provided development kit that includes some useful functions such as visualizing data, calculating mAP, splitting and merging data.
You can download DOTA-v1.5 from either Baidu Drive or Google Drive, according to your network connections. Make sure you download the labelTxt of version 1.5.


Rewrite CSS
Configuration
The 'Rewrite CSS' filter is enabled by specifying:
- Apache:
ModPagespeedEnableFilters rewrite_css
- Nginx:
pagespeed EnableFilters rewrite_css;
in the configuration file. To enable fallback rewriting on CSS we cannot parse, also specify:
- Apache:
ModPagespeedEnableFilters fallback_rewrite_css_urls
- Nginx:
pagespeed EnableFilters fallback_rewrite_css_urls;
Description
This filter parses linked and inline CSS, rewrites the images found
and minifies the CSS. The filter works on CSS found in
 <link rel="stylesheet" type="text/css" href="extStyle.css">   Wow,
 CSS is stylin'.

With the following in extStyle.css
:
div.classy span, div.classy img { display: block; border: none !important; background: none !important; }
Then PageSpeed will rewrite it into:
   <link rel="stylesheet" type="text/css" href="I.extStyle.css.pagespeed.cf.HASH.css">   Wow,
 CSS is stylin'.

And the rewritten file I.extStyle.css.pagespeed.cf.HASH.css
will
contain:

Lian Li Lancool II Review – The Ultimate Mid-Tower?
by Peter DonnellThe Lian Li Lancool One is by far one of the coolest cases on the market right now, check out our review here. Not only did it show their rivals that is can compete or beat them on quality, but they also smashed it on price too. How could Lian Li top that one? They go one louder, that’s how! The Lancool II was something we saw earlier this year at Computex 2019, and we loved it so much, we gave it one of our Best of Computex 2019 Awards. This many features for such a modest price? Oh boy, am I happy to have this one in the office today!
Lian Li Lancool II
It’s pretty much flooded with premium features despite being priced (slightly) under £100. It features dual tempered glass side panels mounted on lift-off hinges. Then you have a built-in PSU shroud, which also features flip down side panels for quick access to the hidden HDD bays. There are mounting covers to hide all the cable management behind the motherboard. Then you have the plentiful radiator and fan support, there’s built-in RGB, there are pre-installed fans, and so much more. Plus, you can really make it your own, as Lian Li has a range of cool aftermarket parts for it too; we’ll price those up on the final page of the review and YES we do have them all here to play with too!
Features
- Hinged Tempered Glass Panels
- Flip-Down Shrouds
- Cable Management Hiding Panels
- PSU Shroud
- Hidden Storage Bays
- Supports up to 280/360mm radiator
- Supports up to Eight Fans
- Pre-Installed Fans
- Addressable RGB Front Panel
Optional Extras
- Vertical GPU kit
- Side diffused aRGB strip
- HDD/SSD Hot-swap kit
- USB 3.1 Type C cable for Lancool II
- VGA anti-sag bracket
What Lian Li Had to Say
“Multifunctional, equipped with all mainstream features, LANCOOL II is born to cater to the market’s demand for a high-performance case at a fair and reasonable price. Available in black for US$89 and white for US$94.99, LANCOOL II is not just ideal for consumers with a tight budget but also perfect for any builders aiming to create the PC of their dream.” – Lian Li
Exterior
The Lian Li Lancool II looks fantastic from the moment you take it out of the box. What really stands out, or more so, doesn’t stand out is the finish.  It’s actually quite stealthy, at least until you see the reflections on the glass. Because it’s all blacked out on the interior, it does make it a mirror when you have no interior lighting. However, that’ll all change once the system is built.
The front panel looks fantastic, but it’s the little details that add up here though. The front panel has an angular design but mixes rounded edges on the sides and more bold angles further in. The same with the ventilation, which uses lots of straight lines, but also some soft curves. The end result looks both aggressive and sleek at the same time, and I love it.
Tucked into the lower section, you’ll find a small Lian Li logo. I love that they’ve done this, it’s a lot less in your face and keeps the front panel looking clean. Plus, you can see those large feet are giving the case amazing ground clearance too.
The front panel has a few more tricks that aren’t immediately apparent. There’s a set of high-quality dust filters behind it, as well as some cool RGB lighting effects, but we’ll get to that shortly.
On the top, you’ll find a huge magnetic dust filter, as well as the front I/O panel.
The I/O is pretty much all blacked out too, with black power controls, and even the USB ports are black rather than blue on the interior.
Under the dust filter, you’ll find plentiful options for mounting a wide range of fans and radiators. Plus, there are options to move them closer or further from the motherboard, improving compatibility with boards that have large VRM cooling.
Down the right side of the case, you’ll find it looks pretty much identical to the left. Another hinged tempered glass window so it looks just as cool from either side!
Plus, there’s another exposed section of the PSU shroud, which opens out; you’ll see that in a moment.
Around the back, it’s business as usual. This is an ATX mid-tower after all, so it has to meet those requirements.
There is a height-adjustable fan/radiator mount, which features a pre-installed exhaust fan.
Below that, there are seven expansion slots, each fitted with reusable metal covers. What I love is that they feature the same perforated design as the front panel vents; it’s the little details that count.
The PSU mount is located at the bottom, under the built-in PSU shroud.
Interior
The case comes with some pretty cool features that you typically don’t see in this price range. The PSU shroud can be accessed from either side of the case without the use of tools. It’s held shut by some properly strong magnets, so just give it a tug and it pulls down. This gives you access to the HDD bays, PSU area, etc.
There are three tool-free drive trays here. Plus, if you buy the optional HDD mount, you can make all of these hot-swappable; handy if you’re building a server.
Once you pull down that lower shroud door, you can then get your hand under the glass and open out the side panel. They’ve on hinges, and also held shut with strong magnets. So no tools, and quick and easy access to your rig. Plus, if you need to, you can lift the glass up off the hinges and put it to one side.
There’s loads of room in here too, as all the HDD bays are tucked out of the way. This is good news for those wanting to install huge graphics cards and thick radiators.
The PSU shroud features loads of ventilation on the top, and there’s even a couple of 120mm mounts on there should you really need them. Plus, there are two massive cable routing cut-outs, so getting cables to the motherboard shouldn’t be an issue.
There’s plenty of width in the case to accommodate wider graphics cards, as well as any custom loop hardware. I love that there’s a slight cut-out to the back of the frame too, allowing your screwdriver to easily reach those screws.
In the back, there’s a 120mm Lian Li fan pre-installed. It’s all blacked out, rather than RGB, but it does have some rubber anti-vibration mounts too, it’s a good quality fan overall. Plus, there’s another located on the top too.
There’s a third one in the front also. That’s pretty sweet to get three pre-installed. However, I think I’d take the top one and put it as two fans in the front, but that’s just me.
The front panel will hold a massive radiator should you need it. The shroud does restrict the size, but there’s a removable panel here so you can really go to town with full-height and thick radiators.
Complete System
Building my demo system inside the Lancool II was an absolute joy. You quickly appreciate the engineering that has gone into making this a truly brilliant PC case. Such as the motherboard mounting, as my MSI board was just too damn wide. Then I remembered, you can move the cable routing!
The panel to the right of the motherboard is designed for ATX. However, undo the two screws, flip it upside down and it now supports E-ATX. This way, the cable routing is right next to the motherboard in either configuration.
Then we have the fantastic RGB. Of course, most of the lighting is coming from our own hardware. However, the front panel RGB still throws a lot of light into the case too.
The cable routing options are superb though. There are cable channels just about everywhere. The only one I would like to add is one below the GPU to give that a shorter run, but that’s hardly a deal-breaker. Plus, we have a few more options anyway, which I’ll get to shortly.
Big CPU cooler? That’s not a problem. Even the massive Noctua NH-D15S fit with ease despite being enormous.
The same goes for our massive RTX 2070 from AORUS. There’s more than enough length for the largest gaming cards on the market. Plus, you have plenty of room for a good size radiator in the front. However, there’s plenty of airflow for a good air-cooled build too.
Then there is the staggering beauty of that front panel RGB. You can control it directly from your motherboard or RGB hub too. However, there’s a button on the front panel to cycle through colours and effects too should you need it.
With all the glass back in place, this really is a properly-well sorted out PC case. Of course, it gets EVEN BETTER!
Just look at that cable routing! Well, lack of it. It looks like a bomb went off behind the panels, but hey, you can’t see the crappy cable routing I did, because it’s hidden. How brilliant is that! Oh and yes, it gets even better still.
Oh and here’s the window back in place, but let’s keep going.
Complete System – But Even Better
Lian Li threw us a full set of the optional components for this build. You’ve got the Type C cable for the front panel, how-swappable backplate, LED strip and anti-sag bracket here.
This one didn’t have a retail box includes. However, it’s clearly the vertical GPU mount and riser cable.
The LED strip just plugs right into the cases extra RGB header, so it’ll pair with the front lighting. The USB Type-C cable speaks for its self though, as does the little GPU anti-sag bracket.
Need to swap out your HDD or SSD’s in a hurry? I don’t, but if you’re running a server and need to switch a drive with no downtime, then this is for you. Just screw it in behind the HDD cage, and your drives become plug and play.
It even comes with some nice SATA cables and plastic light rails for the trays so you can see the drive active LEDs from the front when you flip down the side panel; neat!
So it’s only right we threw in some of the equipment and spruced up our build. Now we have the lighting strip throwing even more light into the case. However, that AORUS GPU has an amazing cooler design, and now it’s on show for all of the world to see!
Amazing!
How Much Does it Cost?
The Lian Li Lancool II is available now with an MSRP of just $89.99 for the black model and $94.99 for the white model. Plus, you can get the vertical GPU kit for just $49.99, which is decent given the build quality, riser cable, etc. The aRGB strip is just $11.99, the Hot-Swap kit is $14.99, the Type-C cable $11.99 and the anti-sag kit is just $7.99. Honestly, though, most of you won’t need the optional gear, but it’s certainly nice to have options. You can check for up to date UK prices here and US here.
Overview
I already knew this is one of the best cases I’ve ever seen. As I said in the introduction, I spend some time tinkering with one in Taiwan when we visited Lian Li’s booth at Computex 2019. We even gave it an award there and then. Boy, how embarrassing it would be if it didn’t earn one today and we hated it. Fortunately, Lian Li has nothing to worry about, I love this case even more today than I ever did before. I’m already thinking I need two more of them to replace all the other cases in the house… yup, I really do like it.
Engineering
Lian Li has always been at the cutting edge when it comes to fantastic case designs. They may have stepped back from only making them from Aluminium, but honestly, it’s the best thing they ever did. This case is every bit as well made as the super expensive behemoths of years gone by. However, this one is affordable to you and me, and still delivers the premium features we would expect on a case twice the price.
The panels snap and lock into place firmly, the thumbscrews don’t snap up on the panels, the dust filters are robust and easily accessed.  It’s all in the details, and there’s plenty of them here.
Not sure why the type-C cable isn’t standard though, but I guess they really wanted to keep the price below $100 right out of the box. Order that cable when you buy one, it’s a good idea to have it I think.
Style
It’s a great looking case, and I dare anyone to deny that. Sure, style is very subjective, but for current market trends, I think the Lancool II is perfectly in tune with today’s market. A big of RGB, tempered glass and lots of ease of use features to help it handle the latest and greatest hardware. Not only that but also present and showcase that hardware with style.
Should I Buy One?
Honestly, I can’t think of a case of this quality. It’s not something that translates into pictures, but it has a robust and reassuring build quality that makes it a joy to use. It’s a stunning design, easy to use, plenty of features, and there are some interesting optional extras. Easily one of the best cases ever made and I really mean EVER made.

Here, we are discussing event store queries, not queries on your read model. An event store query reads one or multiple event streams, aggregates some state from it and makes it accessible. A query is a non-persistent function, that will only be executed once, and return a result. That's it.
To get started, let's take a simple example where we want to query the event-store for how often a given user has changed his username.
$query = $projectionManager->createQuery();
$query
->init(function (): array {
return ['count' => 0];
})
->fromStream('user-123')
->when([
'user-name-changed' => function (
array $state, UsernameChanged $event
): array {
$state['count']++;
return $state;
}
])
->run();
echo 'user 123 changed his name ' . $query->getState()['count'] . ' times';
You can also reset and run the query again:
$query->reset();
$query->run();
Or you can stop the query at any point in time.
$query = $projectionManager->createQuery();
$query
->init(function (): array {
return ['count' => 0];
})
->fromStream('user-123')
->when([
'user-name-changed' => function (
array $state, UsernameChanged $event
): array {
$state['count']++;
$this->stop(); // stop query now
return $state;
}
])
->run();
Queries can be used to answer a given question easily because you don't need to figure out in which read model the data is present (maybe it's not?) and how to query it there (maybe a lot of joins are needed in RDBMS). Also you can do temporal queries very easily, which is hard to impossible to do with any other database system.
Projections are like queries, but they are persistent, the created state is also persistent and can be queried later, and the projection runs forever (in most cases).
Compared to queries, the projectors have a couple of additional methods:
public function getName(): string;
public function emit(Message $event): void;
public function linkTo(string $streamName, Message $event): void;
public function delete(bool $deleteEmittedEvents): void;
$deleteEmittedEvents
flag tells whether or not to delete emitted events.An example:
$projector = $projectionManager->createProjection('test_projection');
$projector
->fromStream('user-123')
->whenAny(
function (array $state, Message $event): array {
$this->linkTo('foo', $event); // create a copy of the event to a new stream
return $state;
}
)
->run();
$projector = $projectionManager->createProjection('test_projection');
$projector
->init(function (): array {
return ['count' => 0];
})
->fromCategory('user')
->when([
'user-registered' => function (array $state, Message $event): array {
$state['count']++;
return $state;
}
)
->run();
This would count all registered users.
There are six options common to all projectors:
OPTION_CACHE_SIZE = 'cache_size'; //Default: 1000
The cache size is how many stream names are cached in memory, the higher the number the less queries are executed and therefore the projection runs faster, but it consumes more memory.
OPTION_SLEEP = 'sleep'; //Default: 100000
The sleep options tells the projection to sleep that many microseconds before querying the event store again when no events were found in the last trip. This reduces the number of cpu cycles without the projection doing any real work.
OPTION_PERSIST_BLOCK_SIZE = 'persist_block_size'; //Default: 1000
The persist block size tells the projector to persist its changes after a given number of operations. This increases the speed of the projection a lot. When you only persist every 1000 events compared to persist on every event, then 999 write operations are saved. The higher the number, the fewer write operations are made to your system, making the projections run faster. On the other side, in case of an error, you need to redo the last operations again. If you are publishing events to the outside world within a projection, you may think of a persist block size of 1 only.
OPTION_LOCK_TIMEOUT_MS = 'lock_timeout_ms'; //Default: 1000
Indicates the time (in milliseconds) the projector is locked. During this time no other projector with the same name can be started. A running projector will update the lock timeout on every loop, except you configure an update lock threshold.
OPTION_PCNTL_DISPATCH = 'trigger_pcntl_dispatch'; //Default: false
Enable dispatching of process signals to registered signal handlers while the projection is running. You must still register your own signal handler and act accordingly. For example to gracefully stop the projection you could do
$projection = $projectionManager->createProjection(
'test_projection',
[ Projector::OPTION_PCNTL_DISPATCH => true, ]
);
pcntl_signal(SIGQUIT, function () use ($projection) {
$projection->stop();
});
$projection->run();
OPTION_UPDATE_LOCK_THRESHOLD = 'update_lock_threshold'; //Default: 0
If update lock threshold is set to a value greater than 0 the projection won't update lock timeout until number of milliseconds
have passed. Let's say your projection has a sleep interval of 100 ms and a lock timeout of 1000 ms.
By default the projector updates lock timeout after each run so basically every 100 ms the lock timeout is set to: now() + 1000 ms
This causes a lot of extra work for your database and in case the database is replicated this can cause a lot of network traffic, too.
This is how the projection works without a threshold set:
1. Process new events. Update lock timeout -> now() + 1000 ms. Sleep 100 ms
2. Process new events. Update lock timeout -> now() + 1000 ms. Sleep 100 ms
3. Process new events. Update lock timeout -> now() + 1000 ms. Sleep 100 ms
...
And this is the projection flow with an update lock threshold set to 700 ms
:
1. Process new events. Sleep 100 ms
2. Process new events. Sleep 100 ms
3. Process new events. Sleep 100 ms
...
7. Process new events. Update lock timeout -> now() + 1000 ms. Sleep 100 ms
8. Process new events. Sleep 100 ms
Projections can also be used to create read models. A read model has to implement Prooph\EventStore\Projection\ReadModel
.
Prooph also ships with an Prooph\EventStore\Projection\AbstractReadModel
that helps you implement a read model yourself.
One nice thing about read model projections is that you don't need a migration script for your read models. When you need to make a change to your read model, you simply alter your read model implementation, stop your current running projections, reset it, and run it again.
The read model projectors have the same options as the normal projectors. See above for more explanations.
$projector = $projectionManager->createReadModelProjection(
'test_projection',
$readModel
);
$projector
->fromAll()
->when([
'user-created' => function ($state, Message $event) {
$this->readModelProjection()->insert(
'name',
$event->payload()['name']
);
},
'username-changed' => function ($state, Message $event) {
$this->readModelProjection()->update(
'name',
$event->payload()['name']
);
}
])
->run();
The projection manager can do the following for you:
While most methods are pretty straightforward, the delete / reset / stop projection methods may need some additional explanation:
When you call stopProjection($name) (or delete or reset) a message is sent to the projection. This will notify the
running projection that it should act accordingly. This means that once you call stopProjection
, it could take a few
seconds before the projection is finally stopped.
All internal projection names are prefixed with $
(dollar-sign), f.e. $ct-
. Do not use projection names starting
with a dollar-sign, as this is reserved for prooph internals.

USDA: America short on sugar
WASHINGTON D.C. (WVLT) -- A statement from the United States Department of Agriculture said the country is short on sugar.
According to the statement, the USDA told the Department of Commerce that the U.S. had "an additional need for sugar" on Monday, November 25.
The USDA said the shortage is due to "adverse weather in both sugar beet and sugarcane regions. In the November 2019 World Agricultural Supply & Demand Estimates Report, the U.S. sugar production projection declined by 572,000 short tons raw value from the previous month."
The statement added that "ongoing" weather issues continue to threaten the supply.
Due to the shortage, the Department of Commerce increased the amount of Mexican refined sugar to be exported.
