Mission Statement: We listen to people with experience of mental health issues, to influence service provision through research and evaluation.
Insight
Our lived experience of mental health issues means that we have insight into the
lives and experiences of other people with these difficulties. We use this insight in all stages
of the evaluation process to produce more valid and useful findings.
Empowering people
Our priority is to empower people who may struggle to participate in
traditional research and evaluation to get fully involved in the whole research and
evaluation process, and to ensure that their voices are always heard.
Alongside
We work alongside the users of the service we are evaluating, co-producing the
research as much as is practical. This can include training them in the research methods we
are using, for example, how to create and carry out interviews. This means they have the
skills and confidence to fully engage with the whole research process alongside CERT
researchers.
Creativity
We believe using and developing creative research methods, especially those
which make the experience less daunting for participants, for example, photographs, music
and creative writing. The use of non-traditional and creative research methods makes
participating more accessible for people who struggle with traditional methods, for
example, because it is more interesting to them and this often reduces the demand placed
on them.
Accessibility
By empowering people and working alongside them, our goal is to remove
the power dynamic which often exists in traditional research. We also ensure the
dissemination of findings is accessible to different audiences, for example, creating formal
written reports, easy-read reports, film and theatre performances. We also seek to make
CERT fully inclusive and accessible to all people who are interested in joining us. On-going
training and development allows people to fully participate.


In order to make consistent, neat and tidy looking website it is important to use grid to devide section of the content. grid based design is basically structuring website with html columns and rows in order to place images and text firstplace before you apply css.
There are various devices with different screen sizes now days and if responsive design is not applied to coding the website could get cut off when the screen gets smaller or the content could misplace when the screen size is stretched. Responsive design will allow the contents to stretch automatically and shrink depending on the size of the user's device and also this will be always centered so it is handy for users as well. media queries definetely benefits users but also the developer as well.
there are semantic tags such as h1-h4, img, form. I think using right tags and right semantic structure helps users to understand the website better. For instance it wouldn't be good if h1 (usually used for heading) is underneath the page and h4 (which is smaller size than h1) is placed at the top of the page as title. Semantic structure is basically a structure that helps users to understand website better by using the code correctly at the right place.

Science is a quantum phenomenon — ‘scientism’ is its observer effect
by Steve FullerThe philosopher Friedrich Hayek originally popularized the term ‘scientism’ in his 1979 book The Counter-Revolution of Science as a synonym for pseudoscience. The word later came to represent the expansion of science into domains where it really has nothing to say, such as evolution into atheism. Nathaniel Comfort now positions ‘scientism’ as the abuse of science in ways that obscure today’s concerns for equity, inclusion and diversity (see N. Comfort Nature 574, 167–170; 2019).
Comfort condemns this version of scientism, in which practices and policies endorsed by scientists have had adverse consequences for vulnerable groups in society — although he is careful not to brand the scientists involved as malicious or ignorant. The implication is that history should help to ensure that such scientism will not happen again.
In my view, it is a misuse of history to oversee the future. What counts as good and bad in scientific practice or in science-based policies can be understood only in retrospect, because our judgement depends on witnessing the consequences. As we move forward in history, those judgements will change. It follows that the moral character of any action is indeterminate at the time it happens. Science itself is a quantum phenomenon — and ‘scientism’ is its observer effect.

I Alone Level-up: Chapter 62
The Shadow Soldiers quickly closed the gap!
However, the ferocious movements of the ice bears were far faster than the Shadow Soldiers .
Boom!
Crack!
A single swipe of the bear’s claw obliterated a Shadow Soldier . If it was a human in that pitch black armor and not a shadow, it would’ve been a gruesome sight .
‘Hmm…’
Jinwoo furrowed his brows .
‘As I thought, was it too much?’
Whether it was strength or size, it unfortunately looked like it was too much for Shadow Soldiers to face the ice bears .
But suddenly, something surprising happened .
‘What the!’
Jinwoo’s eyes widened .
The body of the Shadow Soldier that was destroyed by an ice bear turned to black smoke before it fully hit the ground .
shooooo-
The black smoke gathered at some distance away, then reformed into its original shape .
‘Oh shit!’
Jinwoo’s face lit up .
Undead .
He had forgotten about the true nature of these shadows and was now reminded .
Realizing its attack had no effect, the ice bear panicked and roared .
Roooaaaar!
While the Shadow Infantry kept the ice bears busy, the Shadow Mages had finished their casting .
Flaaaare-!
Bang!
Kaboom!
The fireballs released from the mages’ hands exploded here and there . While the Shadow Infantry caught by the explosion regenerated immediately, the ice bears caught on fire and thrashed about .
“Kuwaaaah!”
“Kuwuuh!”
The Shadow Infantry continued their attacks, swinging and stabbing their swords at the burning bears .
slash!
stab!
At first, the ice bears looked like they had the advantage, but they were slowly being pushed back by the combined attack of the infantry and the mages .
‘Whoa…’
Jinwoo watched the battle with great interest .
The infantry’s fast regeneration .
The mage’s powerful firepower .
The might of Shadow Soldiers exceeded his expectations . The ice bears were soon overwhelmed and were pushed all the way back to the caves . It seemed like the battle was over-
ROOOOAAAAR!
With a roar that shook the eardrums, something giant appeared from the cave .
“That’s…”
Jinwoo’s eyes widened . It was an ice bear a head taller than the rest and also much wider .
ROAR!
At a single swipe of its claw, many Shadow Soldiers were swept away .
BOOM!
Craaaaack!
Even their quick regeneration speed could not keep up .
Crack!
Smash!
“Looks like the alpha made his appearance…”
Of course, he had expected that a den of bears would have an alpha bear . But the thing’s size and power surpassed his expectations .
ROOOOAR!
The giant ice bear slapped away the Shadow Soldiers and ran toward Jinwoo . Suddenly, a message appeared,
ring~
| You are out of mana . The Shadow Soldiers cannot regenerate . . |
| You are out of mana . The Shadow Soldiers cannot regenerate . . |
What?
He checked his mana in panic . Just as the System said, his mana was at zero .
| MP: 0 / 1,860. |
With his mana gone, the Shadow Soldiers no longer regenerated after being destroyed . Instead, they turned into shadow and returned to Jinwoo’s shadow . Jinwoo realized that it was his mana that allowed the soldiers to regenerate .
‘That goddamn mana…’
He found yet another reason to raise his intelligence stat .  The appearance of the alpha had completely turned the tide of the battle . However, Jinwoo still had a trump card up his sleeve .
‘If their boss came out, I should send mine out as well . ’
With his arms crossed, Jinwoo called for the one who was worthy to be called the Shadow Soldier’s boss .
“Ygritte!”
A single shadow slid out from Jinwoo’s shadow . From the shadow rose a knight wearing a helmet adorned with a plumage . Jinwoo raised a chin at the alpha . Ygritte bowed his head to Jinwoo then shot forth towards the giant ice bear .
step, step, step, step!
Ygritte dodged the alpha’s swipe and slid between the ice bear’s legs . While in motion, he quickly took out the daggers at his side and cut the tendons of the beast’s legs .
“Kuwwaaah!”
This was only the beginning .
Unsheathing his long sword, Ygritte skillfully dodged the torrent of attacks from the alpha while carving it up like a sculpture .
Tendons, claws, paws, legs . Bit by bit, the alpha’s flesh was being cut off like being worked by a butcher .
“Huh…”
Jinwoo watched Ygritte’s flowing, artlike movements with great admiration .
The head was the last to go .
Slash!
The giant ice bear’s head was cleanly separated from its body . Before it could hit the ground, Ygritte snatched it from the air . The knight approached Jinwoo then knelt before the Hunter .
drop
Ygritte placed the bear’s head in front of Jinwoo feet, as if offering a trophy to his king . Jinwoo stared at the knight and gulped,
‘If he used his sword from the start back then, could I have defeated him?’
The remaining ice bears were thrown into chaos after losing their leader and were quickly routed by the soldiers . The battle was over . The results greatly satisfied Jinwoo .
| Shadow Infantry (Lv . 2). |
| Shadow Infantry (Lv . 3). |
| Shadow Infantry (Lv . 2). |
| Shadow Mage (Lv . 2). |
The soldiers had leveled up here and there . Since the Shadow Soldiers themselves were Jinwoo’s skill, the Hunter had also gained 3 levels . And above all else,
“Arise . ”
| You’ve succeeded in Shadow Extraction . . |
| You’ve succeeded in Shadow Extraction . . |
| You’ve succeeded in Shadow Extraction . . |
He had earned new friends .
ROOOAR-!
Including the alpha, Jinwoo had selected several ice bears . From their shadows, a large black mass rose .
‘I expected a bear wearing an armor…’
The reality was a little different .
The ‘Shadow Beasts’[1] that arose maintained some semblance to a bear but at the same time had a form that seemed to shift between solid and gas . A black steam continuously spewed from their figures .
‘The visuals are a bit lacking, but still, it’s those ice bears’ shadows . ’
Their strength and capacity for destruction . He would surely have a use for it . Suddenly,
rooooar
Jinwoo’s ears perked up at a cry sounding from a distance . It was not just one or two .
‘Looks like there are more dens in the area . ’
It was getting a little late in the day . He’ll check it out tomorrow .
A bright smile appeared on Jinwoo’s face .
“Uwaaaaak!”
“Kuk!”
His teammates were screaming left and right . Kim Cheol’s eyes were wide open .
‘There is no way!’
That he, Kim Cheol, would fail like this! He was someone would become Baekho’s elite . He had even received special training for that goal . And now, he was going to fail?! The A-ranker could not accept it .
Their party had endured the cold and hunger and fought with yetis . After that were the ice giants . They had lost two of their members but managed to prevail against them too . The Raid appeared to be going smooth .
But .
But!!!
The moment they had triumphed over the ice giants, the White Walkers ambushed them from all directions, as if they had been waiting . Those bastards had been watching their party, waiting for their stamina to hit rock bottom . What followed was a massacre . The Hunters fell, one after another, in an instant .
“L-leader!”
A fallen Hunter stretched a bloodied hand toward Kim Cheol . Kim Cheol stepped backwards . A White Walker appeared out of nowhere and slit the throat of the Hunter on the ground . While the man gurgled and choked on his own blood, the White Walker raised his head towards Kim Cheol . The A-ranker screamed,
“U-uwaaaah!”
He turned around and ran into the forest . The forest had ice bears? Those bears were nothing compared to the yetis, ice giants and the White Walkers . Kim Cheol ran with all of his might . Watching his figure disappear into the distance, the White Walkers raised their bows and took aim . But before they could fire, a White Walker raised his hand and stopped them . It was an ice elf with hair flowing down to his waist . The other White Walkers lowered their bows .
‘ . ’
The long hair pointed and gestured to follow Kim Cheol . One by one, the other White Walkers disappeared from sight .
Kim Cheol leaped through a bush .
“pant, pant, pant . ”
His lungs felt like they were on fire . The image of the White Walkers that smiled while slaughtering his teammates was still fresh on his mind . The man looked down at his hands . The frostbitten hands were losing their sense of touch . His toes had long since lost all feeling . He could not fight properly in his current condition .
 No, if we just didn’t starve for the past few days, we would’ve won . ’
To the bitter end, Kim Cheol could not acknowledge his failure . While muttering to himself, Kim Cheol raised his head .
‘Anyways, how deep am I into the forest?’
He looked around . The smell of blood poked at his nose from somewhere . The man followed the smell . It was close . Moving through the trees, he came upon a clearing and could not believe his eyes .
‘How is this possible?’
In front of the caves were over 20 ice bear corpses . He had wondered why he hadn’t come across a single bear!
“What the?”
He studied the corpses . All the corpses had traces of being cut with something . Some of them also had traces of being burned . Sung Jinwoo and his party flashed across Kim Cheol’s head .
“It can’t be . those bastards did this?”
No . Kim Cheol shook his head . The wounds on the corpses of the ice bears were made with a sword . To his knowledge, Sung Jinwoo’s party did not have a sword user .
‘The two E-rankers didn’t even have a weapon . ’
There was no way they had survived here . Then there was only one other conclusion,
‘The White Walkers are also here!’
His heart sank . He had thought that he managed to get away from those elves . To think that he had wandered into another group of them . With a great fear in his heart, Kim Cheol held his breath and turned back to the direction he had come from .
Further . Faster .
He wanted to get out of the White Walker’s territory .
At the same time .
“Wuwaaaaang!’
An ice bear fell with a death rattle . The Shadow Soldiers swarmed its body and made sure it was dead .
| You’ve leveled up!. |
“Alright . ”
Jinwoo was in a different bear den . It’s been five days since they had entered the Gate . He had gone through three different bear dens since then .
‘Looks like I’ve taken care of every bear in this forest . ’
Thanks to that, both he and his army’s levels had risen quite a bit . At first, it required two soldiers just to hold back an ice bear . Now, a single soldier was capable of winning one on one against the beast . Jinwoo was satisfied . As the abilities of his soldiers rose, he started assigning them different roles . His current limit was 30 shadows . 28 of them would be assigned to combat, while 2 of them would be assigned to the collection of magic cores and meat . Now that he didn’t have to lift a finger to fight or collect drops, life became incredibly convenient for the Hunter .
‘I don’t sense any more magic beasts . ’
It seemed that he had cleared the entire forest .
Then .
‘Is it time to go for the boss?’
There was still about a month to go, at worst several months, until the Dungeon Break . He had no intention of waiting for that to happen .
 ’
A mere magic beast that taunted a Hunter . Its arrogant smile still annoyed Jinwoo .
 After entering the Gate, all he had to eat for the past few days was a single rabbit . His mouth watered at the smell of food .
gulp
The White Walkers might be eating somewhere .
‘But if there’s only few of them…’
He was confident he could take care of them and steal the food . It was a misguided confidence born out of hunger .
‘Let’s check it out . ’
Kim Cheol did his best to quiet his footsteps and carefully approached where the smell was coming from . Finally, he came upon a clearing where Jinwoo’s team was . Kim Cheol’s eyes widened .
‘What?’
The smell of meat was coming from their campfire .
‘How are they still alive?’
However, he did not see one of the E-rank Hunters .
‘Pft . He took the lead with such confidence . Must’ve died first . ’
That much was obvious . But what wasn’t obvious was the scene in front of him . How to… analyze all this? Something was weird .
‘Wait, their clothes…?’
Warm clothes, blankets, tents and other equipment entered his eye . They were clearly prepared for the environment .
‘How the hell?’
While flustered, Kim Cheol’s gaze became affixed on something .
It was a piece of bread next to the meat . There was no way they had found or made bread here . It must’ve been prepared beforehand . His confusion quickly turned to anger .
‘These fuckers…’
grind
Kim Cheol grinded his teeth . These fuckers had all of this with them and walked away on their own .
‘If my hands weren’t frozen, no, if only I wasn’t hungry, I could’ve easily taken care of those ice elves . ’
Thinking about how they greedily hoarded something that should’ve been shared with the Raid team, Kim Cheol could not help it any more . He leaped out into the clearing .
“You bastards!”
Park Heejin jumped in surprise and stood up .
“Kim Cheol? How are you here?”
To be honest, it was hard to say that he was a welcoming sight .  Kim Cheol did not hide his hostility .
“Our party failed in clearing the Dungeon because we lacked proper equipment and food .
Park Heejin could not answer . She feared that bringing up Jinwoo would turn Kim Cheol’s wrath towards Jinwoo . She did not want to turn in the savior of her life .
‘From the start, I didn’t like the way that man looked at Sung Jinwoo . ’
Park Heejin closed her mouth . Seeing her defy his will, Kim Cheol’s rage increased .
“I don’t consider every one of you an accomplice . Who hid all this? I’ll spare the rest of you . ”
The veins in his neck bulged .

His shouting echoed loudly throughout the forest . Kim Cheol realized he would have to up the ante .
“I’m going to count to three . If no one speaks up, I’ll consider all of you equally guilty . ”
Han Songyi tugged at Park Heejin’s sleeves .
“U-unni…”
Park Heejin hugged Han Songyi . Go Myunghwan and Yoon Gijoong also gulped while sweating . Kim Cheol was an A-ranker . Even if they combined their powers, they could not hope to win against him . Still, not one of them betrayed Jinwoo .
“One . ”
Kim Cheol unsheathe the sword at his side .
schiing-
“Two . ”
The Hunters still held their silence .
Mere low-level Hunters dare to disobey him? Kim Cheol’s anger flared .

His eyes turned red with murderous intent .
First would be this woman . The one who betrayed his team and decided to join the weaklings . Park Heejin will be the first to die .
‘Yes . She must’ve been hiding something . That’s why she left my team . ’
That was the only reason he could think of . Kim Cheol stepped up to Park Heejin and finished his countdown .
“Three . ”
Park Heejin closed her eyes .
Suddenly .
“Four . ”
Bam!
Something struck Kim Cheol on the back of the head, and the man fell face forward onto the ground and slid forward for a few feet .
All the Hunters’ eyes opened wide .
“Raid Leader!”
Jinwoo had struck with such a force that his fist was still smoking .
He spoke, appalled,
“Who’s the fucker that really endangered the lives of his comrades?”
.
Translator’s Notes:
[1]: “Shadow Beast” (그림자 마수병): Lit . “Shadow Magic Beast Soldier” . I’ve removed “magic” to distinguish them from magic beasts . The reason was because in the context, “magic beast” was clearly referring to the shadow’s bear-like bestial form, but in the general story, “magic beast” refers to any otherworldly entities found in Dungeons . I wanted to avoid the confusion . Also took out the word “soldier” because it felt redundant in most context cases .

Overview
An API client for AWS Service Catalog. To construct a client, you need to configure a :region
and :credentials
.
servicecatalog = Aws::ServiceCatalog::Client.new(
region: region_name,
credentials: credentials,
# ...
)
See #initialize
for a full list of supported configuration options.
Region
You can configure a default region in the following locations:
ENV['AWS_REGION']
Aws.config[:region]
Go here for a list of supported regions.
Credentials
Default credentials are loaded automatically from the following locations:
ENV['AWS_ACCESS_KEY_ID']
andENV['AWS_SECRET_ACCESS_KEY']
Aws.config[:credentials]
- The shared credentials ini file at
~/.aws/credentials
(more information) - From an instance profile when running on EC2
You can also construct a credentials object from one of the following classes:
- ::Aws::Credentials
- ::Aws::SharedCredentials
- ::Aws::InstanceProfileCredentials
- ::Aws::AssumeRoleCredentials
Alternatively, you configure credentials with :access_key_id
and
:secret_access_key
:
# load credentials from disk
creds = YAML.load(File.read('/path/to/secrets'))
Aws::ServiceCatalog::Client.new(
access_key_id: creds['access_key_id'],
secret_access_key: creds['secret_access_key']
)
Always load your credentials from outside your application. Avoid configuring credentials statically and never commit them to source control.

#wait_until(waiter_name, params = {}) {|waiter| ... } ⇒ Boolean
Waiters polls an API operation until a resource enters a desired state.
Basic Usage
Waiters will poll until they are succesful, they fail by entering a terminal state, or until a maximum number of attempts are made.
# polls in a loop, sleeping between attempts client.waiter_until(waiter_name, params)
Configuration
You can configure the maximum number of polling attempts, and the
delay (in seconds) between each polling attempt. You configure
waiters by passing a block to #wait_until
:
# poll for ~25 seconds
client.wait_until(...) do |w|
w.max_attempts = 5
w.delay = 5
end
Callbacks
You can be notified before each polling attempt and before each
delay. If you throw :success
or :failure
from these callbacks,
it will terminate the waiter.
started_at = Time.now
client.wait_until(...) do |w|
# disable max attempts
w.max_attempts = nil
# poll for 1 hour, instead of a number of attempts
w.before_wait do |attempts, response|
throw :failure if Time.now - started_at > 3600
end
end
Handling Errors
When a waiter is successful, it returns true
. When a waiter
fails, it raises an error. All errors raised extend from
::Aws::Waiters::Errors::WaiterFailed.
begin
client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
# resource did not enter the desired state in time
end
#waiter_names ⇒ Array
<Symbol
>
Returns the list of supported waiters. The following table lists the supported waiters and the client method they call:
| Waiter Name | Client Method | Default Delay: | Default Max Attempts: |
|---|

Elon Musk unveils futuristic Tesla Cybertruck
by ABC7.com staffHAWTHORNE, Calif. -- Elon Musk is taking on the workhorse heavy pickup truck market with his latest electric vehicle.
The CEO of Tesla unveiled a new electric pickup called the Cybertruck on Thursday at the company's design studio in Hawthorne.
The futuristic truck looks like no vehicle on the market.
Musk said inspirations for the angular design include a James Bond car and fighter jets.
"Trucks have been the same for a very long time," Musk said. "Like 100 years, trucks have been basically the same. We want to try something different."
As part of the unveiling, Musk demonstrated the truck's durability. A sledgehammer was taken to the side door twice and it made no noticeable dent.
Metal balls were thrown at the windows. They made substantial golf-ball sized cracks, but did not penetrate through to the interior.
The window cracks seemed to take Musk by surprise, as he said in earlier testing they threw objects at the windows and the glass had not broken.
"Well, maybe that was a little too hard," he joked about the throw.
The company says the electric truck has a range per charge of about 500 miles, with 0-60 acceleration under 2.9 seconds. It has a towing capacity of 14,000 pounds and a payload up to 3,500 pounds. It sells for a base price around $39,900.
The unveiling drew heated reaction on social media, much of it ridicule. Some called it a combination of an El Camino and a DeLorean, others likened the design to a child's drawing of a car, or a low-resolution computer graphic.
With the launch, Tesla is edging into the most profitable corner of the U.S. auto market, where buyers tend to have fierce brand loyalty.
Automotive industry analysts say Tesla's pickup is more likely to appeal to weekend warriors who want an electric vehicle that can handle some outdoor adventure. But it could end up cutting into Tesla's electric vehicle sedan sales instead of winning over traditional pickup truck drivers.
"The needs-based truck buyer, the haulers, the towers at the worksites of the world, that's going to be a much tougher sell," said Akshay Anand, executive analyst at Kelley Blue Book.
Tesla has struggled to meet delivery targets for its sedans, and some fear the new vehicle will shift the company's attention away from the goal of more consistently meeting its targets.

Lesvos is one of the largest Greek islands in the Aegean (after Crete and Evia) and the largest island of the Eastern Sporades.
It is green and fertile and less dependent on tourists than most of the other islands. That said, it is still one of the most popular islands as a tourist destination in this part of Greece.
It has two major sheltered natural harbours on its southern coast, Kolpos Kallonis to the SW and Kolpos Yeras to the SE, as well as the port of entry, Mitilini, on the SE coast. There are also ports at Mithimna (on the north coast) and Sigri (on the west coast).
For full details on clearing into our out of Greece see Greek Formalities. This port is reported to very strict on clearance procedures.
Unless you are using an agent to clear in here, the authorities will want you to tie up at the ferry/Customs dock, which is not suitable for yachts. It is very high and has black dirty tyres for fenders. If the dock is full with commercial vessels when you arrive, you will have to tie up on the town wall and wait to be called back (with your yacht) to the Customs dock for clearance (which could be late in the evening).
You are not permitted to walk over to Customs from the town wall, you must tie up at their dock for clearance, both in and out.
You will need to visit the Customs and Transit Log office, the Port Authority and the Passport Office.
Customs closes at 2100 and opens at 0730 most days, so if you have a dawn departure planned, take your boat to the Customs dock before 1800 the night before to process your departure for the next morning.
Last updated September 2015.
Advice September 2016: Migrants still arrive regularly on Lesbos which can make clearing-in here rather hard work (see comments from 2015 at bottom of page). Docking is also restricted in the main harbour of Mitilini, however the situation is well under control and Lesvos still remains a beautiful island to visit. Chios is a good alternative as a port of entry.
Mitilini (Mytilene)
On entry through the breakwaters the marina lies to port, immediately north of the yacht club in the southern end of the harbour. The inner harbour and town quay can be found at the northern end of the harbour.
Mitilini Inner Harbour
At Mitilini, yachts can moor in the inner harbour on the North or East sides of the town quay, but beware of the soft mud which can allow some types of anchor to drag. Alongside mooring is permitted for short visits, med-moor for longer visits (photo courtesy of MV LeeZe - July 2014). No assistance with line handling. Water and electricity available.
Note that the East quay is the quieter quay, away from traffic and bar noise, however reports received in September 2016 are that this quay is not currently available to visitors due to commercial/migrant traffic, and therefore the North quay is the only option.
To get water and electricity visit the associated office in the port area. Worth it if you are spending more than one night. See Water for more details.
Shelter is good, but to avoid the swell in strong southerlies, move to the SW corner of the harbour if there is space. This harbour can get very smelly as raw sewage empties into the harbour.
Fuel trucks are not permitted to come to the town quay, however there is a fuel station for jerry cans walking distance away.
Mitilini Marina
There is a SETUR marina in the southern corner of the outer harbour, just inside the western end of the detached breakwater. Cruisers report it offers a pleasant relief from the smelly, noisy harbour, and prices are reasonable. It is however quite a distance from the town centre. The marina has a fuel dock but does charge a night's stay for non-berth holders wanting fuel only.
The Tourist Office is open at the port, Monday to Friday from 0900 to approximately 1430. The two ladies inside can help with any enquiries re. port services (the Harbour Master will not assist with this).
Weather forecast (in English) is on VHF channel 01 at 0600/1000/1600/2200hrs UTC.
Mithimna
Located on the north coast of Lesvos, this delightful town with its winding narrow streets and castle on top of the hill, has an outer breakwater which offers good shelter. Go stern or bows-to in any available space, water and electricity available. Holding is poor so check your anchor carefully. The inner harbour has a very narrow entrance channel and is only suitable for very small yachts - shelter inside is excellent.
Sigri
On the remote western coast of Lesvos, Sigri is a typical Greek fishing village relatively untouched by tourists. There is a small quay here available to visiting yachts when no ferry is in town. Alternatively anchor in the bay south of the village. This offers good shelter from the Meltemi. Water is available on the quay.
Kolpos Kalloni
Take care with strong currents running in the narrow entrance to this large, landlocked gulf, on the south coast of Lesvos. Night entrance not recommended. With the Meltemi there can be very strong gusts into the gulf and an uncomfortable sea. There are numerous anchorages once inside and two possible places to tie to a dock: Skala Polikhnitos, a small harbour just east of the entrance; and Skala Kalloni at the head of the gulf.
Plomari
Further along the south coast, inbetween Kolpos Kalloni and Kolpos Yeras, lies the picturesque town of Plomari, famous for its "ouzo". There is space for visiting yachts on the N quay and water is available. Good shelter but not tenable in a southerly. Can be a surge here.
Kolpos Yeras
Lying about 25nm east of Kolpos Kalloni, this smaller landlocked gulf offers an easier entry with less effect from the Meltemi. Again, there a number of anchorages to choose from here with two places offering the possibility of tying up to a dock: Pirgos is a small fishing harbour on the western side of the entrance channel that may have space on its northern quay; and Perama a little further inside the channel.

This project website has been built using Python, API’s, html, css and bootstrap to answer a the question: “How does the weather change as we get closer to the equator?”
We start by generating a random list of lat/lon coordinates. Then, using the Python CitiPy library, we find a city closest to the Lat/Lon coordinates to get a listing of over 600 cities. Then utilizing the OpenWeatherMapAPI, we pulled the weather data for the cities and stored this data in a pandas dataframe.
This dataframe is saved to CSV and the data is analyzed to visualize the relationship between latitude and temperature/humidity/cloudiness/windspeed. The following visualizations were genrated using MatplotLib.


Low Level Hardware Control functionality is contained in two files:
The CPU of Raspberry Pi 1 is Broadcom BCM2835, and the peripheral addresses start from 0x20000000. The CPU of Raspberry Pi 2 is Broadcom BCM2836, and the peripheral
addresses starts from 0x3F000000. A constant in GPIOlowLevel.h defines which Raspberry Pi board to use. On line 23, you will find instruction to comment out exactly one of the following 2 lines:
//#define RPI
#define RPI2
The Raspberry Pi 3 is Broadcom BCM2837 but has the same peripheral address start as the Raspberry Pi 2. Define RPI2 if using a Raspberry Pi 3. It is expected that very few people will still be using a Raspberry Pi 1.
Low level memory for GPIO can be accessed through the newer /dev/gpiomem interface which does not require root access. Unfortunately, the PWM and clock hardware are NOT accessible through /dev/gpiomem, and must be accessed through /dev/mem, which requires running your programs with sudo or gksudo to get root access. A constant is defined for each interface:
#define IFACE_DEV_GPIOMEM 1 // use this only for GPIO
#define IFACE_DEV_MEM 0 // use this for GPIO or PWM and/or clock access
As a user of the GPIO_Thread classes, all you need to know is to use sudo or gksudo when accessing anything other than the GPIO peripheral, and the class (e.g. SimpleGPIO_thread) will use the appropriate interface.
GPIOlowLevel.cpp contains utility functions for peripheral mapping and global variables for the mappings. With the memory mappings available globally, only one mapping is needed for each peripheral. The number of threads using each peripheral is also tracked, so a memory mapping can be deleted when it is no longer needed. Each peripheral had its own mapping. For the GPIO peripheral for instance, we have:

In my Master's Thesis I studied the economic feasibility of energy storage technology (namely flow batteries) in grid-scale applications.
I took part in research on microgrids and the decentralized renewable energy sources' influence on the conventional distribution power systems.
My core tasks were analyzing the clients' demand and electrical supply grid, as well as energy quality monitoring. Also I negotiated with the customers and coordinated the branch offices work.
I inspected electrical installations in buildings, as well as the regional power generation, transmission, and distribution systems (including substations and small power stations).
I verified the current power and electrical networks of the plant, and made updates to their design and schemes, surveyed and maintained the power and electrical equipment.


DECLARE
Statement Creates a new variable. Variables must be declared before use. Variables have script scope. That is, the variable can
be used anywhere else in the script, but it will not be visible to other scripts called using
EXECUTE
, nor to the parent script if this script was itself called with
EXECUTE
. Variable names must begin with an at sign (@
), dollar sign ($
), or colon
(:
).
If the PARAMETER
keyword is used, then the variable becomes a parameter to the script. If the script is
called using EXECUTE
, then the caller must provide a value for this parameter unless the DECLARE PARAMETER
statement specifies an initial-value.
If the DECLARE
statement does not include the PARAMETER
keyword and does not specify an
initial-value, then the variable takes the initial value of NULL
.
Unlike other popular SQL scripting languages, SQL Notebook's DECLARE
statement does not require a data type
to be specified. Variables follow the SQLite convention of allowing any data type to be stored.
PARAMETER

Javascript does not natively support handling of unsigned 32 or 64 bits integers. This library provides that functionality, following C behaviour, enabling the writing of algorithms that depend on it. It was designed with performance in mind and tries its best to be as fast as possible. Any improvement is welcome!
An unsigned 32 bits integer is represented by an object with its first 16 bits (low bits) and its 16 last ones (high bits). All the supported standard operations on the unsigned integer are then performed transparently.
e.g.
10000010000100000100010000100010<PHONE_NUMBER> or 0x82104422) is represented by:
high=1000001000010000
low=<PHONE_NUMBER>100010
NB. In case of overflow, the unsigned integer is truncated to its lowest 32 bits (in case of UINT32) or 64 bits (in case of UINT64).
The same applies to 64 bits integers, which are split into 4 16 bits ones.
In nodejs:
npm install cuint
In the browser, include the following (file is located in the build directory), and access the constructor with UINT32:
` ...
`To instantiate an unsigned 32 bits integer, do any of the following:
var UINT32 = require('cuint').UINT32 // NodeJS
UINT32( <low bits>, <high bits> )
UINT32( <number> )
UINT32( '<number>', <radix> ) // radix = 10 by default
To instantiate an unsigned 64 bits integer, do any of the following:
var UINT64 = require('cuint').UINT64 // NodeJS
UINT64( <low bits>, <high bits> )
UINT64( <first low bits>, <second low bits>, <first high bits>, <second high bits> )
UINT64( <number> )
UINT64( '<number>', <radix> ) // radix = 10 by default
Most methods do modify the object they are applied to. For instance, the following is equivalent to x += y
UINT(x).add( UINT(y) )
This allows for chaining and reduces the cost of the emulation.
To have z = x + y
, do the following:
z = UINT(x).clone().add( UINT(y) )
UINT32( 2, 1 ) // 65538
{ remainder: null, _low: 2, _high: 1 }

Abstract: The Maloney [1] and Luebbers [2] subcell methods can be used to implement dielectric or conducting sheets thinner than the cell size in the FDTD grid. The two methods differ in the treatment of the field components situated half a cell from the thin sheet. For a sheet of infinite size stricken by an incident plane wave, it has been shown by theory and experiments that the Luebbers method suffers from discrepancy at the wide incidence angle, while the Maloney method is exact at any incidence angle [3]. The comparison of Maloney and Luebbers methods has been later extended to dispersive sheets, more specifically, sheets made with the Debye media used in Bio-electromagnetism to model the Human Body tissues (A. Alkandari et al, AP-S/USNC-URSI Symposium, FR-UB.5P, Boston, 2018).
This paper presents the further comparison of the two aforesaid methods in more realistic situations with objects of finite size composed of several thin sheets such as dielectric, conducting or Debye medium sheets. Comparisons with objects composed with both PEC surfaces and thin sheets are also presented. The results from numerical experiments show that the difference between the Luebbers and Maloney methods is affected by the problem to be solved, especially the geometry and size of the thin sheets, the physical parameters of the sheets (permittivity, conductivity, relaxation time), and such other parameters as the location of the observation, for instance, inside or outside an enclosure. The interest of using the Maloney method, which is accurate in any situation, but is more complex to implement in a general purpose computer code, is discussed, with a special emphasize on the case of sheets made with Human Body media.

Purpose
The purpose of this assignment was to use Python, Python APIs and my knowledge of Matplotlib and Pandas to analze data about how weather changes as we move closer to the equator.
To start off this assignment, I pulled data using Open Weather Map's API. With this I was able to gather a dataset of over 500 cities.
After pulling this data and converting it to a CSV file, I use my knowledge of Matplotlib and Pandas to plot various various aspects of weather versus latitude. Factors I looked into included: temperature, cloudiness, wind speed and humidity.
This site showcase my homework as well as what I have learn about HTML and CSS.
I hope you enjoy.
Please Note that all pictures below are clickable!
Below are the charts that I created for this project. Each chart compares the city latitude with different components.
The components are Cloudiness, Humidity, Max Temperature, and Wind Speed.
Each chart can be further explain on it's own section in the Plot section of the dropdown menu

Precompiled Headers
This document describes the design and implementation of Clang's precompiled headers (PCH). If you are interested in the end-user view, please see the User's Manual.

Using Precompiled Headers with clang
The Clang compiler frontend, clang -cc1, supports two command line options for generating and using PCH files.
To generate PCH files using clang -cc1, use the option -emit-pch:
$ clang -cc1 test.h -emit-pch -o test.h.pch
This option is transparently used by clang when generating PCH files. The resulting PCH file contains the serialized form of the compiler's internal representation after it has completed parsing and semantic analysis. The PCH file can then be used as a prefix header with the -include-pch option:
$ clang -cc1 -include-pch test.h.pch test.c -o test.s
Design Philosophy
Precompiled headers are meant to improve overall compile times for projects, so the design of precompiled headers is entirely driven by performance concerns. The use case for precompiled headers is relatively simple: when there is a common set of headers that is included in nearly every source file in the project, we precompile that bundle of headers into a single precompiled header (PCH file). Then, when compiling the source files in the project, we load the PCH file first (as a prefix header), which acts as a stand-in for that bundle of headers.
A precompiled header implementation improves performance when:
- Loading the PCH file is significantly faster than re-parsing the bundle of headers stored within the PCH file. Thus, a precompiled header design attempts to minimize the cost of reading the PCH file. Ideally, this cost should not vary with the size of the precompiled header file.
- The cost of generating the PCH file initially is not so large that it counters the per-source-file performance improvement due to eliminating the need to parse the bundled headers in the first place. This is particularly important on multi-core systems, because PCH file generation serializes the build when all compilations require the PCH file to be up-to-date.
Clang's precompiled headers are designed with a compact on-disk representation, which minimizes both PCH creation time and the time required to initially load the PCH file. The PCH file itself contains a serialized representation of Clang's abstract syntax trees and supporting data structures, stored using the same compressed bitstream as LLVM's bitcode file format.
Clang's precompiled headers are loaded "lazily" from disk. When a PCH file is initially loaded, Clang reads only a small amount of data from the PCH file to establish where certain important data structures are stored. The amount of data read in this initial load is independent of the size of the PCH file, such that a larger PCH file does not lead to longer PCH load times. The actual header data in the PCH file--macros, functions, variables, types, etc.--is loaded only when it is referenced from the user's code, at which point only that entity (and those entities it depends on) are deserialized from the PCH file. With this approach, the cost of using a precompiled header for a translation unit is proportional to the amount of code actually used from the header, rather than being proportional to the size of the header itself.
When given the -print-stats
option, Clang produces
statistics describing how much of the precompiled header was actually
loaded from disk. For a simple "Hello, World!" program that includes
the Apple Cocoa.h
header (which is built as a precompiled
header), this option illustrates how little of the actual precompiled
header is required:
*** PCH Statistics: 933 stat cache hits 4 stat cache misses 895/39981 source location entries read (2.238563%) 19/15315 types read (0.124061%) 20/82685 declarations read (0.024188%) 154/58070 identifiers read (0.265197%) 0/7260 selectors read (0.000000%) 0/30842 statements read (0.000000%) 4/8400 macros read (0.047619%) 1/4995 lexical declcontexts read (0.020020%) 0/4413 visible declcontexts read (0.000000%) 0/7230 method pool entries read (0.000000%) 0 method pool misses
For this small program, only a tiny fraction of the source locations, types, declarations, identifiers, and macros were actually deserialized from the precompiled header. These statistics can be useful to determine whether the precompiled header implementation can be improved by making more of the implementation lazy.
Precompiled headers can be chained. When you create a PCH while including an existing PCH, Clang can create the new PCH by referencing the original file and only writing the new data to the new file. For example, you could create a PCH out of all the headers that are very commonly used throughout your project, and then create a PCH for every single source file in the project that includes the code that is specific to that file, so that recompiling the file itself is very fast, without duplicating the data from the common headers for every file.
Precompiled Header Contents
Clang's precompiled headers are organized into several different blocks, each of which contains the serialized representation of a part of Clang's internal representation. Each of the blocks corresponds to either a block or a record within LLVM's bitstream format. The contents of each of these logical blocks are described below.
For a given precompiled header, the llvm-bcanalyzer
utility can be used to examine the actual structure of the bitstream
for the precompiled header. This information can be used both to help
understand the structure of the precompiled header and to isolate
areas where precompiled headers can still be optimized, e.g., through
the introduction of abbreviations.
Metadata Block
The metadata block contains several records that provide information about how the precompiled header was built. This metadata is primarily used to validate the use of a precompiled header. For example, a precompiled header built for a 32-bit x86 target cannot be used when compiling for a 64-bit x86 target. The metadata block contains information about:
- Language options
- Describes the particular language dialect used to compile the
PCH file, including major options (e.g., Objective-C support) and more
minor options (e.g., support for "//" comments). The contents of this
record correspond to the
LangOptions
class. - Target architecture
- The target triple that describes the architecture, platform, and
ABI for which the PCH file was generated, e.g.,
i386-apple-darwin9
. - PCH version
- The major and minor version numbers of the precompiled header format. Changes in the minor version number should not affect backward compatibility, while changes in the major version number imply that a newer compiler cannot read an older precompiled header (and vice-versa).
- Original file name
- The full path of the header that was used to generate the precompiled header.
- Predefines buffer
- Although not explicitly stored as part of the metadata, the
predefines buffer is used in the validation of the precompiled header.
The predefines buffer itself contains code generated by the compiler
to initialize the preprocessor state according to the current target,
platform, and command-line options. For example, the predefines buffer
will contain "
#define __STDC__ 1
" when we are compiling C without Microsoft extensions. The predefines buffer itself is stored within the source manager block, but its contents are verified along with the rest of the metadata.
A chained PCH file (that is, one that references another PCH) has a slightly different metadata block, which contains the following information:
- Referenced file
- The name of the referenced PCH file. It is looked up like a file specified using -include-pch.
- PCH version
- This is the same as in normal PCH files.
- Original file name
- The full path of the header that was used to generate this precompiled header.
The language options, target architecture and predefines buffer data is taken from the end of the chain, since they have to match anyway.
Source Manager Block
The source manager block contains the serialized representation of Clang's SourceManager class, which handles the mapping from source locations (as represented in Clang's abstract syntax tree) into actual column/line positions within a source file or macro instantiation. The precompiled header's representation of the source manager also includes information about all of the headers that were (transitively) included when building the precompiled header.
The bulk of the source manager block is dedicated to information about the various files, buffers, and macro instantiations into which a source location can refer. Each of these is referenced by a numeric "file ID", which is a unique number (allocated starting at 1) stored in the source location. Clang serializes the information for each kind of file ID, along with an index that maps file IDs to the position within the PCH file where the information about that file ID is stored. The data associated with a file ID is loaded only when required by the front end, e.g., to emit a diagnostic that includes a macro instantiation history inside the header itself.
The source manager block also contains information about all of the
headers that were included when building the precompiled header. This
includes information about the controlling macro for the header (e.g.,
when the preprocessor identified that the contents of the header
dependent on a macro like LLVM_CLANG_SOURCEMANAGER_H
)
along with a cached version of the results of the stat()
system calls performed when building the precompiled header. The
latter is particularly useful in reducing system time when searching
for include files.
Preprocessor Block
The preprocessor block contains the serialized representation of the preprocessor. Specifically, it contains all of the macros that have been defined by the end of the header used to build the precompiled header, along with the token sequences that comprise each macro. The macro definitions are only read from the PCH file when the name of the macro first occurs in the program. This lazy loading of macro definitions is triggered by lookups into the identifier table.
Types Block
The types block contains the serialized representation of all of
the types referenced in the translation unit. Each Clang type node
(PointerType
, FunctionProtoType
, etc.) has a
corresponding record type in the PCH file. When types are deserialized
from the precompiled header, the data within the record is used to
reconstruct the appropriate type node using the AST context.
Each type has a unique type ID, which is an integer that uniquely
identifies that type. Type ID 0 represents the NULL type, type IDs
less than NUM_PREDEF_TYPE_IDS
represent predefined types
(void
, float
, etc.), while other
"user-defined" type IDs are assigned consecutively from
NUM_PREDEF_TYPE_IDS
upward as the types are encountered.
The PCH file has an associated mapping from the user-defined types
block to the location within the types block where the serialized
representation of that type resides, enabling lazy deserialization of
types. When a type is referenced from within the PCH file, that
reference is encoded using the type ID shifted left by 3 bits. The
lower three bits are used to represent the const
,
volatile
, and restrict
qualifiers, as in
Clang's QualType
class.
Declarations Block
The declarations block contains the serialized representation of
all of the declarations referenced in the translation unit. Each Clang
declaration node (VarDecl
, FunctionDecl
,
etc.) has a corresponding record type in the PCH file. When
declarations are deserialized from the precompiled header, the data
within the record is used to build and populate a new instance of the
corresponding Decl
node. As with types, each declaration
node has a numeric ID that is used to refer to that declaration within
the PCH file. In addition, a lookup table provides a mapping from that
numeric ID to the offset within the precompiled header where that
declaration is described.
Declarations in Clang's abstract syntax trees are stored
hierarchically. At the top of the hierarchy is the translation unit
(TranslationUnitDecl
), which contains all of the
declarations in the translation unit. These declarations (such as
functions or struct types) may also contain other declarations inside
them, and so on. Within Clang, each declaration is stored within a declaration
context, as represented by the DeclContext
class.
Declaration contexts provide the mechanism to perform name lookup
within a given declaration (e.g., find the member named x
in a structure) and iterate over the declarations stored within a
context (e.g., iterate over all of the fields of a structure for
structure layout).
In Clang's precompiled header format, deserializing a declaration
that is a DeclContext
is a separate operation from
deserializing all of the declarations stored within that declaration
context. Therefore, Clang will deserialize the translation unit
declaration without deserializing the declarations within that
translation unit. When required, the declarations stored within a
declaration context will be deserialized. There are two representations
of the declarations within a declaration context, which correspond to
the name-lookup and iteration behavior described above:
- When the front end performs name lookup to find a name
x
within a given declaration context (for example, during semantic analysis of the expressionp->x
, wherep
's type is defined in the precompiled header), Clang deserializes a hash table mapping from the names within that declaration context to the declaration IDs that represent each visible declaration with that name. The entire hash table is deserialized at this point (into thellvm::DenseMap
stored within eachDeclContext
object), but the actual declarations are not yet deserialized. In a second step, those declarations with the namex
will be deserialized and will be used as the result of name lookup. - When the front end performs iteration over all of the declarations within a declaration context, all of those declarations are immediately de-serialized. For large declaration contexts (e.g., the translation unit), this operation is expensive; however, large declaration contexts are not traversed in normal compilation, since such a traversal is unnecessary. However, it is common for the code generator and semantic analysis to traverse declaration contexts for structs, classes, unions, and enumerations, although those contexts contain relatively few declarations in the common case.
Statements and Expressions
Statements and expressions are stored in the precompiled header in both the types and the declarations blocks, because every statement or expression will be associated with either a type or declaration. The actual statement and expression records are stored immediately following the declaration or type that owns the statement or expression. For example, the statement representing the body of a function will be stored directly following the declaration of the function.
As with types and declarations, each statement and expression kind
in Clang's abstract syntax tree (ForStmt
,
CallExpr
, etc.) has a corresponding record type in the
precompiled header, which contains the serialized representation of
that statement or expression. Each substatement or subexpression
within an expression is stored as a separate record (which keeps most
records to a fixed size). Within the precompiled header, the
subexpressions of an expression are stored prior to the expression
that owns those expression, using a form of Reverse
Polish Notation. For example, an expression 3 - 4 + 5
would be represented as follows:
IntegerLiteral(3) |
IntegerLiteral(4) |
BinaryOperator(-) |
IntegerLiteral(5) |
BinaryOperator(+) |
| STOP |
When reading this representation, Clang evaluates each expression
record it encounters, builds the appropriate abstract synax tree node,
and then pushes that expression on to a stack. When a record contains N
subexpressions--BinaryOperator
has two of them--those
expressions are popped from the top of the stack. The special STOP
code indicates that we have reached the end of a serialized expression
or statement; other expression or statement records may follow, but
they are part of a different expression.
Identifier Table Block
The identifier table block contains an on-disk hash table that maps
each identifier mentioned within the precompiled header to the
serialized representation of the identifier's information (e.g, the
IdentifierInfo
structure). The serialized representation
contains:
- The actual identifier string.
- Flags that describe whether this identifier is the name of a built-in, a poisoned identifier, an extension token, or a macro.
- If the identifier names a macro, the offset of the macro definition within the preprocessor block.
- If the identifier names one or more declarations visible from translation unit scope, the declaration IDs of these declarations.
When a precompiled header is loaded, the precompiled header
mechanism introduces itself into the identifier table as an external
lookup source. Thus, when the user program refers to an identifier
that has not yet been seen, Clang will perform a lookup into the
identifier table. If an identifier is found, its contents (macro
definitions, flags, top-level declarations, etc.) will be deserialized, at which point the corresponding IdentifierInfo
structure will have the same contents it would have after parsing the headers in the precompiled header.
Within the PCH file, the identifiers used to name declarations are represented with an integral value. A separate table provides a mapping from this integral value (the identifier ID) to the location within the on-disk hash table where that identifier is stored. This mapping is used when deserializing the name of a declaration, the identifier of a token, or any other construct in the PCH file that refers to a name.
Method Pool Block
The method pool block is represented as an on-disk hash table that
serves two purposes: it provides a mapping from the names of
Objective-C selectors to the set of Objective-C instance and class
methods that have that particular selector (which is required for
semantic analysis in Objective-C) and also stores all of the selectors
used by entities within the precompiled header. The design of the
method pool is similar to that of the identifier
table: the first time a particular selector is formed during the
compilation of the program, Clang will search in the on-disk hash
table of selectors; if found, Clang will read the Objective-C methods
associated with that selector into the appropriate front-end data
structure (Sema::InstanceMethodPool
and
Sema::FactoryMethodPool
for instance and class methods,
respectively).
As with identifiers, selectors are represented by numeric values within the PCH file. A separate index maps these numeric selector values to the offset of the selector within the on-disk hash table, and will be used when de-serializing an Objective-C method declaration (or other Objective-C construct) that refers to the selector.
Precompiled Header Integration Points
The "lazy" deserialization behavior of precompiled headers requires their integration into several completely different submodules of Clang. For example, lazily deserializing the declarations during name lookup requires that the name-lookup routines be able to query the precompiled header to find entities within the PCH file.
For each Clang data structure that requires direct interaction with
the precompiled header logic, there is an abstract class that provides
the interface between the two modules. The PCHReader
class, which handles the loading of a precompiled header, inherits
from all of these abstract classes to provide lazy deserialization of
Clang's data structures. PCHReader
implements the
following abstract classes:
StatSysCallCache
- This abstract interface is associated with the
FileManager
class, and is used whenever the file manager is going to perform astat()
system call. ExternalSLocEntrySource
- This abstract interface is associated with the
SourceManager
class, and is used whenever the source manager needs to load the details of a file, buffer, or macro instantiation. IdentifierInfoLookup
- This abstract interface is associated with the
IdentifierTable
class, and is used whenever the program source refers to an identifier that has not yet been seen. In this case, the precompiled header implementation searches for this identifier within its identifier table to load any top-level declarations or macros associated with that identifier. ExternalASTSource
- This abstract interface is associated with the
ASTContext
class, and is used whenever the abstract syntax tree nodes need to loaded from the precompiled header. It provides the ability to de-serialize declarations and types identified by their numeric values, read the bodies of functions when required, and read the declarations stored within a declaration context (either for iteration or for name lookup). ExternalSemaSource
- This abstract interface is associated with the
Sema
class, and is used whenever semantic analysis needs to read information from the global method pool.

I had been researching many different substances on the web lately. And to my shear delight I discovered 5-MeO-DMT. Being interested in herpetology for many years I found a Colorado River Toad (Bufo Avarius) at a local pet store. Up to 25% the toads venom is 5-MeO-DMT.
So far I have only tried the venom twice here are my accounts. On my first attempt I collected the toad’s venom early in the day, and let it dry. At about 9:00 the same night I gathered all the venom from the first milking and scraped it into a pipe. It wasn't much that was collected, my toad is fairly young (only 3 inches long) and I was inexperienced in squeezing the venom from the glands.
With much anticipation I held my flame under my glass pipe, and began to inhale the oddly pleasant smoke. But my pipe was clearly not effective for freebasing the 5-MeO, and I must have lost half of the smoke, to my absolute horror. What little I did inhale made me feel very stoned, and gave me the familiar feeling of coming up on mushrooms. Colors seemed enhanced, brighter and almost glossy. Overall I was very disappointed, but that disappointment wouldn't last long.
The next day I milked the toad again, since I had only milked it once the first day. This time my technique had improved quite a bit, and I collected what looked to be twice as much as last time. This time I made a pipe out of a plastic pen tube, and made an enclosed bowl out of aluminum foil, so no smoke could escape.
This trip, like my last try, was in my darkened room. I had a candle burning, one soft light on, and Massive Attacks album Mezzanine playing on my computer. And for good luck my new pet toad was in his tank right next to me. I was sort of scared as I put the pipe to my lips, hoping that it would work, and REALLY hoping that I wouldn't take too much. As I lit my lighter I heard the venom snap and crackle from the heat, and I gently sucked the smoke into my lungs. It was a fairly large hit that filled my lungs with smoke.
 By the time this pins and needles effect got to my eyes, I was tripping VERY hard. Shadows began to move, and slither up my wall. Everything in my room took on a strange glow, and the fear grew inside me. After 20 seconds the effects were still coming on hard and fast, and I felt like I would almost freak out. But then a calm came over me as the drug reached its peak.
The visual effects were similar to a moderate dose of mushrooms or LSD, but the body high was extremely intense. I lay in my bed, hardly moving for about the first minute, time slowed quite dramatically. I was using a winamp visualization program, and it slowed to a crawl, so did my clock. But the music seemed to go on at its normal pace. The only thing I could think for the first 5 minutes was 'Dear God it worked!!.' Everything was so beautiful that it amazed me to no end. I ended up playing with my dog for a while, I really enjoyed touching anything I could get my hands on.
At this dosage, which is quite unknown, I learned nothing spiritual or anything profound. I found this experience to be filled with some neat visuals and mostly just a feeling of “Holy shit”. 5-MeO wears off way to fast; I wished I could have stayed in that bed for much longer. The trip peaked after about 30 seconds, and stayed fairly intense for maybe 5 minutes. The quick decline in effects continued for 20 minutes, but I was left with a nice afterglow. After an hour I felt I was completely back to baseline. My only complaint about the experience is the lingering smell that 5-MeO-DMT leaves. I’d be careful if you are trying to do this while other people are home, the smell stays for hours and would be hard to explain.
Well that’s all I have so far, but I assure you, I WILL be doing this again. Happy toading everyone :-D
