I'm a Sir Henry Wellcome fellow based at the UCL Max Planck Centre for Computational Psychiatry and Ageing Research at UCL and the Division of the Humanities and
Social Sciences at Caltech.
I use computational modelling and neuroimaging to understand the mechanisms underlying symptoms of anxiety and depression.
You can find my CV
here.
I started my academic career with a BSc in Psychology and MSc in Cognitive Neuroscience at the University of Sussex, before completing a PhD at
the Institute of Psychiatry, Psychology and Neuroscience at King's College London, where I focused on neuroimaging markers of depression and bipolar disorder.
Please feel free to get in touch if you'd like to talk to me about anything research-related, whether it's science or career advice. Reaching out to random scientists can be
intimidating for junior students/researchers, particularly if you're from a background that's under-represented in academia - I want to make it clear here that I will always welcome this

Research
Aversive learning processes
A growing literature suggests that anxiety and depression may be associated with alterations in processes governing learning about reward and punishment. I use
behavioural tasks tapping into appetitive and aversive learning to understand how individual differences in specific aspects of the learning processes may
underlie symptoms of these disorders.
Offline replay in learning and planning
Many of the symptoms of anxiety and depression, such as rumination and worry, occur "offline" - i.e. when we are not actively encountering any positive or negative
feedback. I investigate how offline processes, such as sequential replay and reactivation, function in motivationally salient environments using MEG and EEG. This
work aims to provide a foundation for future investigations into the role played by these processes in symptoms such as worry.
Brain networks in anxiety and depression
Key brain networks are thought to be structurally and functionally affected in affective and anxiety disorders. I use MRI to answer questions about how these networks
are affected in these disorders, and how their dysfunction may relate to specific symptom profiles.

Files CCore/inc/net/PTPSupport.h CCore/src/net/PTPSupport.cpp
PTP Support is a PTP service with 6 functions. The service id is 1. Function ids are 1-6.
const ServiceIdType ServiceId = 1 ; const FunctionIdType FunctionId_Len = 1 ; const FunctionIdType FunctionId_Seed = 2 ; const FunctionIdType FunctionId_Session = 3 ; const FunctionIdType FunctionId_Echo = 4 ; const FunctionIdType FunctionId_ErrorDesc = 5 ; const FunctionIdType FunctionId_Exist = 6 ;
Function Len has the following input/output:
struct LenInput { LenType to_server_info_len; LenType to_client_info_len; }; struct LenOutput { LenType to_server_info_len; LenType to_client_info_len; };
This function is used to cap input/output packet lengths. Client sends its limits to the server. Limits should not exceed MaxInfoLen (1440). Server downs these limits to its own limits and sends back to the client. These values can be used further to calculate different data limits in other PTP service/functions.
Function Seed has the following input/output:
struct SeedInput { }; struct SeedOutput { uint64 seed1; uint64 seed2; };
The return value is a random 128-bit value. It can be used for random seeding.
Function Session has the empty input/output:
struct SessionInput { }; struct SessionOutput { };
This function is used to inform the server, that this particular client starts a new session and all remaining state information from the past should be discarded, if any. It is recommended, that PTP client-server interaction starts with Len and Session functions.
Function Echo has the following input/output:
struct EchoInput { uint32 delay_msec; uint8 len; uint8 data[len]; }; struct EchoOutput { uint8 len; uint8 data[len]; };
This function echoes the input data after the given delay in milliseconds. The maximum delay value is 1000*60*60 (1 hour).
Function ErrorDesc has the following input/output:
struct ErrorDescInput { ServiceIdType service_id; FunctionIdType function_id; ErrorIdType error; }; struct ErrorDescOutput { uint8 len; uint8 str[len]; };
This function returns a text description of the particular error code. The input contains a service/function ids and the error code. The output is a text (byte) string, up to 255 byte length.
Function Exist has the following input/output:
struct ExistInput { ServiceIdType service_id; FunctionIdType function_id; }; struct ExistOutput { ServiceIdType service_id; FunctionIdType function_id; ErrorIdType error; };
This function can be used to check if the given service/function id combination is implemented by the server. Output contains the copy of the input and the error code. The error code is NoError or NoFunction.
The file txt/cpp/PTPSupport.txt.cpp contains this service definition.
PTPSupportBase.h defines these entities withing namespace PTPSupport.
Support functions can be performed using the ClientDevice class. There are several helper classes for this. They are located withing the namespace PTP.
Each class constructor take the pointer to the ClientDevice object and the reference to the PacketSet<uint8> object. The packet set is used to take a transaction packet.
The method perform() or perform_guarded() performs the transaction. It is a blocking call. The first argument is a timeout, both MSec and TimeScope argument types are allowed. perform() returns a boolean value to indicate a success, perform_guarded() throws an exception in case of error. If the operation successfully finished, the result can be obtained by the correspondent get() methods.
class Support_Exist : NoCopy
{
....
public:
Support_Exist(ClientDevice *client,PacketSet<uint8> &pset);
bool perform(TimeoutType timeout,ServiceIdType service_id,FunctionIdType function_id);
enum ResultType
{
NotExist,
Exist,
Unknown
};
friend const char * GetTextDesc(ResultType result);
ResultType getResult();
};
perform() takes the ServiceId and FunctionId as arguments.
getResult() returns the result as an enum value. If the operation is failed, the Unknown is returned.
class Support_ErrorDesc : NoCopy
{
....
public:
Support_ErrorDesc(ClientDevice *client,PacketSet<uint8> &pset);
bool perform(TimeoutType timeout,ServiceIdType service_id,FunctionIdType function_id,ErrorIdType error_id);
StrLen getDesc() const;
};
perform() takes the ServiceId, FunctionId and ErrorIdType as arguments.
getDesc() returns the StrLen error description from the internal buffer. If the operation is failed, "Unknown error" is returned.
class Support_Seed : NoCopy
{
....
public:
Support_Seed(ClientDevice *client,PacketSet<uint8> &pset);
bool perform(TimeoutType timeout);
void perform_guarded(TimeoutType timeout);
uint64 getSeed1() const;
uint64 getSeed2() const;
};
getSeed1() and getSeed2() is the seed. Zero is returned in case of error.
class Support_Echo : NoCopy
{
....
public:
Support_Echo(ClientDevice *client,PacketSet<uint8> &pset);
bool perform(TimeoutType timeout,uint32 delay_msec,FillType &fill);
void perform_guarded(TimeoutType timeout,uint32 delay_msec,FillType &fill);
PtrLen<const uint8> getEcho() const;
};
perform() takes the delay and the reference to the FillType class as arguments. This class is responsible for the echo data creation. It must implement the following interface:
class Fill { public: ulen getLen(); void fill(PtrLen<uint8> buf); };
getEcho() returns the echoed data from the internal buffer. The empty range is returned in case of error.

Ketamine...
During my first experience with K, I felt very strange, feeling blocked out from my mind and body, as if I was disconnected. After that, I spent the next month or so taking K during the weekends, enjoying the experience, but not being dependent on it.
After that month and a half, a friend and I decided to go on a binge night at my house, buying ten bags from a friend. Each bag where we live contains about 0.1-0.2 grams, depending on the dealer. The prices of the bags I will not mention, for my paranoid state of mind fears that it might lead to discovery of who I am and/or where I currently am.
This binge night, I experienced my very first 'K-hole'.
I remember thinking right after, 'shit, this was too much, I have to run to the bathroom and back before this hits'. So I went to the bathroom, did my business, and the last thing I remember was making it back to my room and closing my door. After that, memory in the physical world stops, and my memory of the experience begins.
I felt that I was being pulled away in different directions, and become one with a white light, and saw many strange things along the way. During this 'dream' state, I felt as if I was one with everything, and that I had entered a safe, warm place.
It has now been about 6 months since that day, and I've been trying to recreate that experience, but I never have. My tolerance has slowly been building up, where it is now to the point that doing three bags (0.6g) will not induce a K-hole. It induces the physical anaesthetic, and the mental state of being useless and sitting in one place and enjoying it. Any larger single-line dose and it is wasted, for my recollection of the experience becomes faded.
I have had a few different experiences though during this time, and when listening to soft music, such as a song like Pachelbel's Cannon, positive thoughts enter my mind, as well as a feeling of spiritual and emotional peace.
But now, I have developed a deep dependency on K, and these days take it because without a dosage the world feels very tiring, boring and lonely, and I only seem to feel normal again when I have snorted a line or two.
Strangely enough I am doing fairly well at school, being a straight B student, but socially I am starting to have problems, because more and more of my friends are becoming worried about me, since I am almost always in a catatonic state.
Personally I take 4-5 doses a day, usually in the 0.2 mg per dose stage, so that I may produce the catatonic state, which these days is the only state I feel comfortable to be in.
While other people may differ, I never re-created that first K-hole again, and that feeling of being in a safe place is gone, replaced by a simple feeling of normality, something which has scared many of my friends, and causes great worry to those close to me.
I rarely use any other drug, including alcohol, since I've started using K, and whenever the supplies are cut I have great problems and turn to other drugs just to 'bide the time' until a new supply comes in.
In a new concentrated effort, I have been clean for the past 10 days now, except for smoking one joint, and looking back, I'm not really sure losing 6 months of my life sitting down and always being fucked up was worth it, but what I can be sure of is, I will never escape the memory of using the drug.
With its positive and negative effects, I will still say this is the best drug I have ever used, but the thought lingers in the back of my head that I could have done something more useful with 6 months instead of being a binge user.
I'm 16 years old, and what I fear most is that when I'm 26 I'll still be doing the same thing.
It's a fear that's not worth it.

MIDI support
Similarly to OSC, several Faust architectures also provide MIDI support. This allows Faust applications to be controlled from any MIDI device (or to control MIDI devices). MIDI is also the preferable way to control Polyphonic instruments.
MIDI messages description in the dsp source code
MIDI control messages are described as metadata in UI elements. They are decoded by a special architecture MidiUI class that will parse incoming MIDI messages and update the appropriate control parameters, or send MIDI messages when the UI elements (sliders, buttons...) are moved.
Description of the possible standard MIDI messages
Below, when a 7-bit MIDI parameter is used to drive a button or checkbox, its maximum value 127 maps to 1 ("on") while its minimum value 0 maps to 0 ("off").
A special [midi:xxx yyy...] metadata needs to be added in the UI element description. The more usual MIDI messages can be used as described here:
-
[midi:ctrl num] in a slider or bargraph will map the UI element value to (0, 127) range. When used with a button or checkbox, 1 will be mapped to 127, 0 will be mapped to 0,
-
[midi:keyon pitch] in a slider or bargraph will register the UI element's state-variable to be driven by MIDI note-on velocity (an integer between 0 and 127) of the specified key between 0 and 127. When used with a button or checkbox, 1 will be mapped to 127, 0 will be mapped to 0,
-
[midi:keyoff pitch] in a slider or bargraph will register the UI element's state-variable to be driven by MIDI note-off velocity (an integer between 0 and 127) of the specified key between 0 and 127. When used with a button or checkbox, 1 will be mapped to 127, 0 will be mapped to 0,
-
[midi:key pitch] in a slider or bargraph will register the UI element's state-variable to be driven by MIDI note-on velocity (an integer between 0 and 127) of the specified key between 0 and 127. When used with a button or checkbox, 1 will be mapped to 127, 0 will be mapped to 0. Note-on and note-off events will be handled,
-
[midi:keypress pitch] in a slider or bargraph will register the UI element's state-variable to be driven by the MIDI key-pressure (an integer between 0 and 127) from MIDI key,
-
[midi:pgm num] in a slider or bargraph will map the UI element value to the progchange value, so progchange message with the same num value will be sent. When used with a button or checkbox, 1 will send the progchange message with num value, 0 will send nothing,
-
[midi:chanpress num] in a slider or bargraph will map the UI element value to the chanpress value, so chanpress message with the same num value will be sent. When used with a button or checkbox, 1 will send the chanpress message with num value, 0 will send nothing,
-
[midi:pitchwheel] in a slider or bargraph will map the UI element value to (0,16383) range. When used with a button or checkbox, 1 will be mapped to 16383, 0 will be mapped to 0.
A simple example
An example with a volume slider controlled with MIDI ctrlchange 7 messages :
//-----------------------------------------------
// Volume MIDI control in dB
//-----------------------------------------------
import("music.lib");
smooth(c) = *(1-c) : +~*(c);
gain = vslider("Volume [midi:ctrl 7]", 0, -70, +4, 0.1) : db2linear : smooth(0.999);
process = *(gain);
A complete testing example named midi_tester.dsp is available in the Faust distribution examples folder.
The MIDI support can be activated using the -midi option when building the audio application with the appropriate faust2xxx command. The following table (table tab:midiarch) lists Faust's architectures which provide MIDI support.
| Audio system | Environment | HTTP support |
| Linux | ||
| Alsa | Qt | yes |
| Jack | Qt | yes |
| Mac OS X | ||
| CoreAudio | Qt | yes |
| Jack | Qt | yes |
MIDI synchronization
MIDI clock based synchronization can be used to slave a given Faust program. The following three messages need to be used:
-
[midi:start] in a button or checkbox will trigger a value of 1 when a start MIDI message is received
-
[midi:stop] in a button or checkbox will trigger a value of 0 when a stop MIDI message is received
-
[midi:clock] in a button or checkbox will deliver a sequence of successive 1 and 0 values each time a clock MIDI message is received, seen by Faust code as a square command signal, to be used to compute higher level information.
A typical Faust program will then use the MIDI clock stream to possibly compute the BPM information, or for any synchronization need it may have. Here is a simple example of a sinus generated which a frequency controlled by the MIDI clock stream, and starting/stopping when receiving the MIDI start/stop messages:
import("music.lib");
// square signal (1/0), changing state at each received clock
clocker = checkbox("MIDI clock[midi:clock]");
// ON/OFF button controlled with MIDI start/stop messages
play = checkbox("ON/OFF [midi:start] [midi:stop]");
// detect front
front(x) = (x-x') != 0.0;
// count number of peaks during one second
freq(x) = (x-x@SR) : + ~ _;
process = osc(8*freq(front(clocker))) * play;

The saxon:doctype
instruction is used to insert a document type declaration into the
current output file. It should be instantiated before the first element in the output file is written. It must be used only
when writing a final result tree (not a temporary tree) and only when writing text nodes. The reason for these
restrictions is that saxon:doctype writes directly to the serialized output stream (internally it uses disable-output-escaping
to achieve this). It is not possible to represent a doctype declaration as a node on a temporary tree.
The saxon:doctype
instruction takes no attributes. The content of the element is a template-body
that is instantiated to create an XML document that represents the DTD to be generated; this XML
document is then serialized using a special output method that produces DTD syntax rather than
XML syntax.
If this element is present the doctype-system and doctype-public attributes of xsl:output
should not
be present.
The generated XML document uses the following elements, where the namespace prefix "dtd" is used for the namespace URI "http://saxon.sf.net/dtd":
|
dtd:doctype |
Represents the document type declaration. This is always the top-level element. The element
may contain dtd:element, dtd:attlist, dtd:entity, and dtd:notation elements. It may have the following
attributes: |
|
dtd:element |
Represents an element type declaration. This is always a child of dtd:doctype. The element
is always empty. It may have the following attributes: |
|
dtd:attlist |
Represents an attribute list declaration. This is always a child of dtd:doctype. The element
will generally have one or more dtd:attribute children. It may have the following attributes: |
|
dtd:attribute |
Represents an attribute declaration within an attribute list.
This is always a child of dtd:attlist. The element
will always be empty. It may have the following attributes: |
|
dtd:entity |
Represents an entity declaration.
This is always a child of dtd:doctype. The element may be empty, or it may have content. The
content is a template body, which is instantiated to define the value of an internal parsed
entity. Note that this value includes the delimiting quotes. The xsl:entity element
may have the following attributes: |
|
dtd:notation |
Represents a notation declaration.
This is always a child of dtd:doctype. The element will always be empty. It
may have the following attributes: |
Note that Saxon will perform only minimal validation on the DTD being generated; it will output the components requested but will not check that this generates well-formed XML, let alone that the output document instance is valid according to this DTD.
Example:
<xsl:template match="/">
<saxon:doctype xsl:extension-element-prefixes="saxon">
<dtd:doctype name="booklist"
xmlns:dtd="http://saxon.sf.net/dtd" xsl:exclude-result-prefixes="dtd">
<dtd:element name="booklist" content="(book)*"/>
<dtd:element name="book" content="EMPTY"/>
<dtd:attlist element="book">
<dtd:attribute name="isbn" type="ID" value="#REQUIRED"/>
<dtd:attribute name="title" type="CDATA" value="#IMPLIED"/>
</dtd:attlist>
<dtd:entity name="blurb">'A <i>cool</i> book with > 200 pictures!'</dtd:entity>
<dtd:entity name="cover" system="cover.gif" notation="GIF"/>
<dtd:notation name="GIF" system="http://gif.org/"/>
</dtd:doctype>
</saxon:doctype>
<xsl:apply-templates/>
</xsl:template>
Although not shown in this example, there is nothing to stop the DTD being generated as the
output of a transformation, using instructions such as xsl:value-of
and xsl:call-template
.
It is also possible to use xsl:text
with disable-output-escaping="yes"
to output DTD constructs not
covered by this syntax, for example conditional sections and references to parameter entities.


Van overturns on M4 near Swansea
The occupants managed to escape with minor injuries but police warned people to check the condition of their vehicle
by Katie-Ann GupwellPolice have shared these pictures of a van which overturned on the M4.
The incident happened on the busy road near Morriston, Swansea on Thursday evening. Traffic monitors showed slow traffic on the M4 eastbound at Ynysforgan.
Tweeting the images at 7.17pm, South Wales Police wrote: "Luckily all occupants walked away with just minor injuries as they were wearing seatbelts. A quick check of the tyres shows a possible cause. Always check your tyres and always wear a seatbelt."
Shortly afterwards, there was an accident on the M4 which left the Briton Ferry Bridge partially blocked and caused very slow traffic.


--- title: Model Averaging in Genomics? author: Drew Tyre date: '2020-03-13' draft: yes categories: - Research tags_include: - reply - statistics slug: model-averaging-genomics ---
Over a year ago I received an email about my model averaging post:
I came across your blog post https://drewtyre.rbind.io/post/rebutting_cade/ searching for information about model combination and model averaging.
I work in human genomics, developing risk scores for predicting disease based on genetic markers (SNPs). We have now run into this ‘problem’ where we have multiple such scores from different sources, that when assessed in a regression model (cox or logistic) are all highly significant at the same time and their effect size is not completely attenuated by the inclusion of the other predictions (I am assessing the association of each score, which is a vector, with a specific disease outcome, say binary). Each score is standardised to zero-mean and unit variance.
This observation has lead us to try combining these different predictions into one ‘composite’ prediction, which seems to substantially outperform any one of the individual predictions (i.e., combining three weakly-correlated predictions, with hazard ratios of 1.3, 1.4, and 1.5, respectively, gives a hazard ratio of 1.8 for the composite score). I believe this is due to Jensen’s inequality, as you explain in your blog.
My question is, are you aware of good mainstream literature on this topic explaining why combining predictions is a good idea? In statistical genetics and human genomics this practice has not caught on so the concept seems like voodoo to them.
My answer then:
I’m not that familiar with genomics data, although I know big sample sizes and many predictors create unique problems!
It’s not clear to me what is meant by a composite prediction. When model averaging it would be unlikely for the odds ratio of the prediction to increase over what the individual models predict. Maybe impossible.
In any case, from a Bayesian perspective Hooten et al. is the go to source, and for more details on using AIC I would look at Burnham and Anderson.
But, is it impossible?
tl;dr: A word of warning: what follows is me thinking while typing. If you’re looking for a coherent story with a clear conclusion, you will be disappointed.
In the model averaging world, there are two scenarios of reality. In the Bayesian scenario, there is a small set of weak predictors, all the others are zero, and all of the predictors are in the model set. In the AIC scenario many variables matter with exponentially decreasing effect sizes, and a random sample of the variables are included in the model set.

Now I need a plausible model set. I don’t know what genomics people do, but I imagine they test individual genes first. I will also put in a null model to bound the set. Normally I would put in a global model, but if there are hundreds or thousands of genes that would be impractical.
models <- list(y~x[,1], # this is a weird construction but it works
y~x[,2],
y~x[,3],

y~x[,9],
y~x[,10],

set.seed(83849035)
df <- s1()

modnames <- map_chr(models, deparse)

I had to play around with different random seeds to get a set that had all three “true” predictors in the top set. 1 is always the top, but 2 and 3 often drop way down along with the null model. So how does a model average prediction stack up against the top model? First i’ll extract the “hazard ratios”, which I believe is just \(e^{\beta_1}\)
hr <- map_dfr(s1fits[1:10], broom::tidy, conf.int = TRUE) %>%
filter(term != "(Intercept)") %>%
mutate(hr = exp(estimate),
lcl = exp(conf.low),
hcl = exp(conf.high),
AICc = map_dbl(s1fits, AICc)[1:10])
ggplot(data = hr,
# mapping = aes(x = fct_reorder(term, AICc), y = hr)) +
mapping = aes(x = AICc, y = hr)) +
geom_point() +
geom_errorbar(mapping = aes(ymin = lcl, ymax = hcl), width = 0.1) +
labs(x = "Term ordered by AICc",
y = "Hazard Ratio") +
geom_hline(yintercept = 1, linetype = 2)
That’s kind of a cool plot. The two predictors that give the strongest results are well separated from the rest. How does the model averaged prediction compare? I think that has to be necessarily worse than the top predictor because the model averaging will shrink the prediction back towards zero, but let’s see.
Now, what is a “compound prediction”? Also, I’m not really sure how to get a single hazard ratio. Reading between the lines, I wonder if they are doing something with the predictor variables, like using the sum of the top predictors. I’ll use the top 3 because they had hazard ratios significantly different from 1.
df$compound <- with(df, x[,1] + x[,3] + x[,5]) # dplyr doesn't like matrix columns
s1cmpd <- glm(y~compound, data = df, family = binomial)
broom::tidy(s1cmpd, conf.int = TRUE) %>%
filter(term != "(Intercept)") %>%
mutate(hr = exp(estimate),
lcl = exp(conf.low),
hcl = exp(conf.high)) %>%
select(hr, lcl, hcl)
## # A tibble: 1 x 3
## hr lcl hcl
## <dbl> <dbl> <dbl>
## 1 1.99 1.47 2.86
Hmmm. That’s also worse than either of the single predictors. But it could be that it happens sometimes.
I wonder what happens if I use the sum of the true predictors.
df$true <- with(df, x[,1] + x[,2] + x[,3]) # dplyr doesn't like matrix columns
s1true<- glm(y~true, data = df, family = binomial)
broom::tidy(s1true, conf.int = TRUE) %>%
filter(term != "(Intercept)") %>%
mutate(hr = exp(estimate),
lcl = exp(conf.low),
hcl = exp(conf.high)) %>%
select(hr, lcl, hcl)
## # A tibble: 1 x 3
## hr lcl hcl
## <dbl> <dbl> <dbl>
## 1 2.17 1.54 3.26
The top predictor has a hazard ratio of 2.23, so this is slightly worse. What about the two variables that had AICc values far below the others?
df$true <- with(df, x[,1] + x[,3]) # dplyr doesn't like matrix columns
s1true<- glm(y~true, data = df, family = binomial)
broom::tidy(s1true, conf.int = TRUE) %>%
filter(term != "(Intercept)") %>%
mutate(hr = exp(estimate),
lcl = exp(conf.low),
hcl = exp(conf.high)) %>%
select(hr, lcl, hcl)
## # A tibble: 1 x 3
## hr lcl hcl
## <dbl> <dbl> <dbl>
## 1 2.29 1.57 3.54
So that is higher, but not by much. I guess I could get a single hazard ratio by calculating a model averaged prediction and then using it in a glm.

name_scope
A context manager for use when defining a Python op.
Inherits From: name_scope
tf.compat.v2.name_scope
This context manager pushes a name scope, which will make the name of all operations added within it have a prefix.
For example, to define a new Python op called my_op
:
def my_op(a, b, c, name=None): with tf.name_scope("MyOp") as scope: a = tf.convert_to_tensor(a, name="a") b = tf.convert_to_tensor(b, name="b") c = tf.convert_to_tensor(c, name="c") # Define some computation that uses `a`, `b`, and `c`. return foo_op(..., name=scope)
When executed, the Tensors a
, b
, c
, will have names MyOp/a
, MyOp/b
,
and MyOp/c
.
If the scope name already exists, the name will be made unique by appending
_n
. For example, calling my_op
the second time will generate MyOp_1/a
,
etc.
__init__
__init__(name)
Initialize the context manager.
name
: The prefix to use on all names created within the name scope.ValueError

"Then come with me at once," said the fine-looking man.
"But I have my duty to do here," remonstrated Lowri.
"Come with me 'at once," repeated the fine-looking man; and he spoke in such a tone that Lowri had not the courage to say no.
She mounted behind him, and off they went, like the flight of a swallow, through Cwmllan, down Nant yr Aran, and over the Gader to Cwm Hafod Ruffydd, before the poor woman had time even to say "Oh!"
When they reached Cwm Hafod Ruffydd, Lowri saw a magnificent mansion before her, splendidly lit up with such lamps as she had never seen before. They entered the court, and a crowd of servants in gorgeous liveries came to meet them.
"Lead her to the bed-chamber," said the fine-looking man; and Lowri was conducted through the great hall into a bed-chamber which surpassed in luxury and splendour anything she had ever dreamed of, let alone seen. There the mistress of the house, to whose aid she had been summoned, was awaiting her.
Lowri nursed her with her accustomed skill, and stayed with her until the lady was completely recovered. It was the pleasantest episode of Lowri's life; there was festivity day and night; dancing, singing and merriment went on ceaselessly. She was very sad when the time came for her to depart. The fine-looking man gave her a great, heavy purse, with the order not to open it until she reached her own house. Then he bade one of his servants escort her back the same way that she had come. When she reached home she opened the purse, and to her intense delight it was full of gold. She lived happily on these earnings to the end of her life.


Making a Super Short Video
Short Videos
Below is a list of chort clips to inspire you. Unfortunately, you'll have to watch an advertisement before a few of these (sorry!). They are mostly around thirty seconds in length, but a few are longer. We picked the longer one because they have concepts that translate well to shorter videos.
Above each clip we pointed out a few good (and occasionally some bad) points to look out for as you watch, but don't feel limited to our point of view. Watch closely and judge for yourself what works and what doesn't.
30 Seconds to Know
NBC News has an awesome segment called 30 Seconds to Know. It's a large collection of informative videos that (excluding the roughly ten second intro) are thirty seconds long. We've picked one to show you, but there are hundreds more on their website if you need more inspiration. As you're watching, pay attention to how clearly and concisely the expert relays the information. Also notice that, while they use text and effects to enhance the video and emphasize certain points, they don't over do it and lose focus. When making your video, keep in mind this balancing act between using enough effects to keep a viewers attention and few enough effects to not distract from the main point.
 It was made for a comptetition called the Oscar Experience and if you YouTube that term, you'll find a lot more thirty second examples. Notice how Evan has a sound track playing behing the voice-over which really adds depth and a touch of professionalism. Also, notice that, while he has a lot of words on the screen, they are short simple terms that are easy to read and understand quickly. Imagine how overwhelming this might feel if he had whole sentences instead of key terms displaying.
Runaway CEO Pay
This is another thirty second clip. It's super clean and simple but expresses a powerful point in an equally powerful way. While watching it, pay attention to the way the animation is used to really accentuate the point. Notice the use of dramatic pauses that build anticipation, for example the pause between the initial statement and when "1965" appears and the pause before the pan out on the second group of workers. Again notice the brevity of the sentences and how they are simple and incorporate clear stats and numbers.

X Factor All Stars contestant Brenda Edwards says she had no idea show had been cancelled
The singer claims she only found out Simon Cowell pulled the plug on the show by reading it in the papers
by Tiffany WallisBrenda Edwards has insisted she was booked for X Factor All Stars but claims she was not told that the show had been axed.
Speaking to the Daily Star Sunday , the Loose Women panellist, 45, revealed she only learned Simon Cowell had pulled the plug on the show by reading it in the papers.
The former contestant told the publication: "We were waiting to hear what was going on.
"And then I saw it in the paper that the series had been cancelled."
After discovering the show had been scrapped, Brenda told the paper she was "surprised" and thought it was a "shame".
She also revealed she didn't know what the reasons behind the show's cancellation were.
A show spokesperson has hit back at Brenda's claims and explained she was "not due to take part" in the All Stars series.
Brenda originally found fame on the ITV show in 2013 when she came in fourth place after being mentored by Sharon Osbourne.
After impressing with her soulful voice, Brenda sailed through the competition and made it all the way to the live shows.
During one episode, Simon compared Brenda to Shirley Valentine as he praised her new look.
At the beginning of the month it was announced that music mogul Simon, 60, decided to cancel his upcoming X Factor spin-off.
A host of winners and contestants from across the years were set to battle it out in the new version of the ITV show.
The Mirror exclusively revealed Simon scrapped the idea at the last minute after struggling to get any big name former stars to take part.
Leona Lewis was among those believed to have backed out.
Now Simon's launching X Factor: The Band instead, and plans to find a new pop supergroup.
He said the winners of his new show will do more than get a record contract, they'll also launch a new wave of music, "UK-Pop".
2011 winners Little Mix are also set to launch a rival BBC talent show, The Search, to put together a band to support them on their next tour.

⭑ Note: Unlike the out of the box security code solution, access and ID tokens require setting up a process on AODocs to whitelist client IDs. This is not currently possible out of the box.
In general, a Bearer token is a piece of data that acts as a permit to operate on resources, passed in the Authorization header of requests.
Two main types of Bearer tokens exist:
A user who has access to resources on a resource server tells the authorization server it's OK for the client app to have the same access. The client app then gets a permit (token) it can present to the resource server with each request.
The main reason to use access or ID tokens (instead of security code) is to provide the client app with secure delegated access to server resources on your behalf. It allows authorizing a client app to access and manipulate server resources within a specific scope/time, and without exposing the user's credentials to the app.
When a client app gets the user to authenticate, Google can generate two types of tokens:
Both types of tokens can be generated in a single authentication request, but only one of them is usually necessary. After this step, the AODocs authentication flow is similar, but with some key differences.
Each request to AODocs APIs must satisfy two requirements: identify the user, and certify that the provided token was generated by Google. Either of the tokens issued by Google is capable of providing this proof, so the client app can choose which token serves its purposes better.
💡 Tip: The ID token is sufficient to perform AODocs-only actions. Meanwhile, the access token has the same capability, but additionally allows AODocs to impersonate the user to get access to the Drive scopes required to call Drive APIs.
There are many ways of obtaining an OAuth 2.0 token. Describing all the use cases is beyond the scope of this article. You can read more about Google's approach on the following Google documentation pages:
When you receive tokens from Google, they should look something along the lines of the following.
{
"access_token": "ya29.Il-3B5J8...Fhl3a-yRjpg",
"id_token": "eyJhbGc8i...AaNVQ"
"expires_in": 3600,
"token_type": "Bearer",
"scope": "openid https://www.googleapis.com/auth/userinfo.email",
"refresh_token": "1//04c68...AGAQSNwF-L9Ir2s...M9yc8AqB-u04JncA...68nWovE"
}
⭑ Note: Access tokens usually start with the string
ya29.
, and because they're opaque (not actual data but pointers to data elsewhere), they're usually shorter than ID tokens. The latter are longer because they contain actual data, encoded into three pieces: header, claims, and signature.
Once you have obtained a token, you select which token is more appropriate for your use case:
You can access AODocs APIs by including one of the tokens as an Authorization
HTTP header's Bearer
value:
Authorization: Bearer < access_token | id_token >
GET https://aodocs.altirnao.com/api/document/v1 HTTP/1.1
Authorization: Bearer [YOUR_TOKEN] \
Accept: application/json \
Content-Type: application/json \
{
"libraryId": "Rngc1ug8K6WmL3IjZ8"
}
All Bearer tokens have a built-in expiration. If you requested offline access to token scopes, you can refresh tokens as necessary without having to prompt the user for permission.
Token errors occur only when the token is:
All of these result in status code 401: Unauthorized
as listed in HTTP status codes and error scenarios.
To create, manage, and troubleshoot your tokens, see the Google Developers OAuth 2.0 Playground.

Posted on 26/07/2020 at 6:00 PM by The Vibe.
After respawning my practice of blogging, a couple of friends have suggested me to write about my journey of switching from Mechanical Engineering to working as a Software Engineer. A lot of things in the 5 years of my life at IIT Kharagpur shaped me up for this switch - and that's what I've tried to summarise in this blog post.
Having had the opportunity to know seniors and batchmates who managed to do a similar switch, I've also tried to connect the dots between our journeys from my perspective. That way, folks who're following the same pursuit can learn from my/our mistakes and probably skip making the same mistakes themselves.
In this blog post, I've split our journeys into 4 phases:
Pretty much everyone starts out with this phase, in fact, irrespective of what they want to pursue. The very first step to realize what you want to do, is realizing that you don't want to keep doing whatever you're currently doing.
And in my case, it didn't even take much convincing for me to figure out that Mechanical Engineering wasn't my cup of tea. In our first year of engineering, we all had a shared curriculum. I didn't have concerns with most of them, but these two courses were in a league of their own - namely, Engineering Drawing (ED) and Mechanics.
Remember ED? It's the course where you get introduced to MiniDrafter; a tool that you use as a prank gun for the rest of your college life; until you suddenly remember you're 2 months away from graduation and finally pass down the legacy to some junior of yours! It's that dreadful course where people with poor hand-eye coordination skills just give up and accept any passing grade. I can go on and on with the rants, but you get the drift. ¯\(ツ)/¯
Now, the probability of me escaping these two courses after my first year was close to zero. IITs usually have a concept of "Department Change" (aka DeptC) wherein the top scorers among the freshers get to change their department (Terms & Conditions apply, of course). But sadly, with these two courses present in my first year, there was no chance my CGPA would come even remotely close to switching my branch to CS.
At that moment, reality dawned on me. The dreadful realization that the next four years of my life would be filled with permutations and combinations of such Mech courses; because, wellllllll, Mechanical Engineering.
Right away after ending my first year, I had a very undeniable clarity that neither did I have the interest to take Mech as a career nor did I have the skills to justify it. In hindsight, I think it was a blessing in disguise that my first-year experience had given me a crystal clear focus that I'd have to pursue something outside of Mech. That is, if I hadn't been annoyed enough, I wouldn't have had enough motivation to start as early to switch to something else. In fact, I saw this problem occurring with some of my friends even till their placements - they didn't have much hate for Mech, but they didn't love it either. Such a situation results in half-hearted learning and half-assed effort; which is at least as bad as it sounds.
"Life is too short to tolerate something just for the sake of it - spend more time enjoying your passion!"
Once you've made up your mind (and heart) that you'd love to pursue something else, the next step is to find out where your passion lies. And typically, it does take some time to explore multiple options and figure out where our genuine interest lies.
In my case, I definitely used up my freshman and sophomore years trying to consider all different options; as Mechanical Engineering was turning out to be very chill for me (yup, sarcasm). The first couple of options I contemplated were: Coding, Finance and Management.
Management seemed too much for a freshman, and the finance domain just had too many technical mumbo-jumbo terms that I'd have to first get acquainted with - which seemed like an overkill back then, and; is also tough to self-learn without someone pointing you towards all the right resources. Okay, yup, maybe I was intimidated by these two domains back then. I probably still am, but now I do have friends who can point me to the right resources now. And that's where it began:
So, I thought I'd give the Software domain a try. I went through the very risky process of dual-booting my Windows laptop with Ubuntu; thankfully, I was able to complete the dual-boot without turning my laptop into a piece of brick that has no OS to boot into. When I opened up the terminal, I was already drawn into it - I still can't put it into words why.  Life decisions are often hard to explain - especially when the reason is childish.
Now, I was ready to deep-dive into the coding domain - yay! Where do I start though? Software Engineering has way too many sub-genres, which leads to two main problems if you're not coming from a CS degree background:
Think about it - everyone prefers to always be in their comfort zone ideally. But hey, life does have other plans - so how do you make sure you still get to be in your comfort zone despite the uncertainties of life? The trick is to regularly step out by yourself, and make yourself comfortable with more of these circumstances. That way, you eventually build a large enough comfort zone and maintain a good trade-off between staying and stepping out of this comfort zone.
And sometimes, stepping out of your comfort zone can be the best thing to ever happen to you.
To give an example of the cons of a comfort zone, I started out with plain static front-end web development near the end of my freshman year as it was very intuitive to see the changes get reflected in the UI. Testing out the changes was as easy as opening an HTML file in the browser!
But I got a bit too comfortable with it that I didn't want to explore much outside of front-end, as it was too immersive to not keep spending time. Learning javascript has definitely made life easier in hindsight, but still, it took me almost an entire semester to start moving out of my comfort zone of front-end. There's a whole world outside to venture! Baby steps.
The next logical step to explore was checking out the back-end aspects of the same, and then maybe trying to make the front-end and back-end work together (and that's the circle of full-stack development). Most people choose Python3 as their first high-level language, but I picked up Ruby as my first high-level language, as it just reads very naturally.
In hindsight, it was indeed functional programming that had this effect of Ruby reading very naturally to me. And it's become a great paradigm in recent times, being adopted by most of the languages!
When getting started in this journey of transition, there are two types of people. There are the independent lone wolves who can venture anything on their own, and then there are those who prefer to progress as a wolf pack. Lone wolves don't depend on anyone and can work at their own pace/will; but typically, it's good to have an active community of folks (wolfpack) that share their learnings and guide you when you need help.
A support group of sorts, to share exciting stuff and also to fall back on when you feel overwhelmed. In retrospect, this role was kind of played by Metakgp in my college tenure - there were always people who'd help out with a query. The best part is, it's not an official "club"/"society" where there's a hierarchy of juniors/seniors - so, it served as a barrier-free environment for everyone to interact freely and improve mutually.
I got started with simple plain Ruby scripts and then moved onto other sophisticated things - that involved web frameworks (Rails), web scraping, API integrations, growth hacking and more. And here's where my very first Internship at Pipecandy came in very handy! I put my full-stack skills to good use and also got to learn a lot of things I use on a day-to-day basis like git commands.
If you're just getting started with coding and don't know git yet, git is a version management tool that gives you the flexibility to collaborate with others and has your code changes in different branches; even though most folks see the actual value added by git when they've broken the master branch and need to revert back to a working version.
Now that I had gathered some knowledge on good Ruby practices and libraries, I next delved into open-source development to give back to the community and also learn back better best-practices. Or at least, that's how it started. But with more open-source CLIs and tools that I started using from GitHub very regularly, the more invested I became with the open-source community!
I came across the SciRuby organization (also known as Ruby Science Foundation) and noticed that they already had some progress in building computational tools in Ruby. With most Rubyists coming from a Rails background and being one myself, I loved the idea of helping to make their tools more easily integrable with Rails. And that's exactly what I did as a part of my GSOC 2017 project; I contributed IO integrations between daru (Data Analysis in RUby) and Rails via daru-io. Feel free to read this very creatively-written (self-proclaimed) GSOC post on the same.
Fast forward by one year, I bagged a splendid summer internship at Intuit India - thanks again to my open-source contributions!
Oh, yup, spoiler alert - one major drawback of pursuing Software Development without a CS background is discrimination. A lot of companies use your degree as a means of filtering out your application from the system. As a result, it's tough to even get to the interview stage.  (Cough) Privilege. (Cough)
On the brighter side, this trend is changing slowly for the better and companies are now starting to consider open-source contributions as an alternative to the mainstream competitive programming skills and CS degree requirements. If you're interested in reading rants, I'm sure you will love my Internship Hunt!
Every time I recount my memories from college after having made the switch, the first motivational image that comes to my mind is the iconic scene from MSD's biopic. Another level of hard relate - as MSD too couldn't put up for long with what he was doing at Kharagpur, even though this was also a very crucial formative phase for him, faced hardships, beat the odds and then went on to shine in his passion:
And for what it's worth, at least all the hardships have given me enough content to write about! ¯\(ツ)/¯
Sorry for drifting away with the rants - it's a rabbit-hole, but a very luring one. Alright, let's get back to our timeline. After all the Ruby learnings, I wanted to venture more unknown territories. I hopped to the next big thing: Data Analysis & Machine Learning. Given my experience with the daru library, this was a nice segue. There are a couple of domains (IP/Image Processing, NLP/Natural Language Processing, Video Processing, etc.) where these "smart" concepts can be applied and it's preferred to take a course on the theory of ML and understand the math first, to understand what the code exactly does.
If you're just using an existing ML model in your project, there are lots of repositories for each of the domains that can provide you with object detection/face detection functionality in your projects with barely a few lines of code. But mind you - if you'd rather like to add new features to improve the performance of such-existing models, that's a whole other ball-game altogether!
In my case, I took up an NLP project for my BTech project and an IP project for my MTech project. Both of these projects were not about using an existing model, but also adding some improvement to existing architectures. And they typically involve a LOT of work, to go through the process of literature review, familiarising with ALL the existing methods that have been tried out so far, and then ideating something new. Converting this idea into code is often the easiest part in such research-oriented pursuits. This is something you'd wanna do if you're trying to go for a PhD or have explored multiple domains and then chosen a specific domain to deep-dive into. But unless you're clear about it, I'd suggest you save it for the future.
The major difference between the Padawan phase and the Jedi phase apart from the skill-set/knowledge is the level of maturity. It's very typical for a Padawan to get fixated on their favourite language, deep-dive into a specific language/framework and show-off their rapid software building skills in it. However, the Padawan transitions into a Jedi when they come to appreciate all languages/frameworks for the pros & cons each of them provide, and try to understand the programming patterns and concepts that unite them. An accurate depiction of Jedis finding programming patterns in the Naruto-verse would look something like this:
Let me give an example between my Padawan and Jedi phases. As a Padawan, I was deeply invested into Ruby & Rails - I loved the concept of ActiveRecord for the simplistic interface it provides to communicate with the back-end database! But as a Jedi, the language-specific knowledge that is acquired gets transformed and organized more generically - ie, in terms of concepts and programming patterns. To draw a parallel to the same example, a Jedi would focus more on learning the parts that'd be language-independent - such as MVC (Model-View-Controller) pattern adopted by Rails (and a lot of other web frameworks as well, ORM (Object Relation Mapping) adopted by RoR via ActiveRecord, etc.
That way, it's easier to learn a new language/framework based on the known common concepts/patterns and it's possible to even adopt hybrid best practices among languages!
"You don't just learn software; you also learn how to learn software over time"
There's a real benefit to starting with the hands-on software development first and then reading up its corresponding theory. It's because you often tend to reverse engineer the solution depending on your need and then relate it with the theory/coursework. Such a theory that you learn yourself by correlating with your hands-on experience tends to stick with you for a long long time - in stark contrast to what you crammed for an exam.
However, the only con with not having a structured layout of a CS degree is that you may end up skipping some of these basic concepts covered in some courses - either because it didn't seem interesting to you and you were tempted to knowingly skip ahead, or you were not even aware of its mere existence and didn't even get a chance to study it.
This was one of the golden tips given to me by Bala Dutt - one of the folks who took my internship interview at Intuit. Bala also came into the Software Engineering realm with a non-CS background and is now a revered Principal Engineer! His exact suggestion during my pre-final year was to cover as much unchartered territory in CS coursework during the final year. Thanks to his advice - I felt the need to retrospect the gaps I had left and covered them during my final year.
Or at least, that's what I thought. I joined back full-time at Intuit India as an SE1 and got allotted the Data Platform. Most of the work here involved handling/processing data in a scalable way through data lake concept and uses a generic ensemble of technologies like Hive, Hadoop, Spark, Kafka, Scala, etc. This was surely a blind spot for me, as I had never gotten to work on such a huge amount of data and was never exposed to this domain previously. I not only lacked just the specific tech-stack familiarity, but also had to read on why/how these technologies are scalable whereas traditional datastores aren't as scalable relatively. For example, why build a data lake for scalability; when you can just work on MYSQL with lots and lots of shards?
It was a bit comforting to know that it wasn't exactly an issue of being from a non-CS background. Rather, the majority of the newly graduated folks are just not acquainted with the domain unless they've specifically done an internship in the same domain. Almost everyone gets to learn this during their first job hands-on. Yay, validation! Around eleven months in, I feel more confident in the domain of distributed computing and how the tech-stack ensemble comes together to give a scalable solution.
Of course, it's always possible to get dealt blindspots in Software Development, irrespective of your experience/background - no one has a perfect repertoire of knowing all concepts, domains and tech-stacks. Rather, it's about how you handle blindspots based on the concepts you already know and how you correlate them. It's the same thing with life also no?
And this is another thing that distinguishes Padawan from a Jedi. So, one way to handle blindspots is to proactively improve your repertoire. Proactively - ie, without waiting for an external factor to get you to do it. My way of doing this has been by actively participating in hackathons. Hackathons are usually a competitive space, but not for me. For me, a hackathon is an opportunity to throw myself out of my comfort zone and getting to learn something new quickly. A coder's version of improv performance, if you will. Of course, this has a lot to do with consciously choosing to step outside your comfort zone:
Software Development has too many sub-domains. And the more of these domains you're familiar with, the better your pace at learning a new domain quickly; as you've more distributed knowledge and have a better chance of finding something to relate with the new domain. Also, with each domain you're familiar with, the more all-round you become as a Software Developer (IMO) and the more the number of prospective opportunities you give yourself to delve into!
"Always keep your options open."
Also, as a Jedi, you get to train and mentor Padawans of your own - guiding them on their path to become a Jedi themselves one day. It's always a wholesome experience when they transition and start guiding their own Padawans! It's the circle of life, in action.
If you've made it to the end of this post, you have incredible perseverance and passion to endure in your pursuit!
I hope that reading this post has been a fun experience and not just an information dump. Now that we're almost done with the blog post, I've saved the most important for the last! I'd like to take some time to emphasize the importance of following your passion and not switching to the Software domain just because of the "hefty" pay. Be rest assured, it does involve a lot of time and effort to compensate for what you get paid for. And especially with this realm heavily relying on one to constantly sharpen their edge and technical prowess; it's very easy to get burnt out and lose direction.
"No effort seems like a lot when you're passionate about it, and; any minimal effort can seem like heavy lifting if you're not passionate about it."
Yup, Mechanical Engineering, I'm seeing you.
Follow your passion - YOLO!

Creates a
BloomFilter with the expected number of insertions and a default expected
false positive probability of 3%. |

Creates a
BloomFilter with the expected number of insertions and expected false
positive probability. |

create(long expectedNumItems,
long numBits)
Creates a
BloomFilter with given expectedNumItems and numBits , it will
pick an optimal numHashFunctions which can minimize fpp for the bloom filter. |
abstract double |
expectedFpp()
Returns the probability that mightContain(Object) erroneously return
true
for an object that has not actually been put in the BloomFilter . |
abstract boolean |
isCompatible(BloomFilter other)
Determines whether a given bloom filter is compatible with this bloom filter.
|
abstract BloomFilter |
mergeInPlace(BloomFilter other)
Combines this bloom filter with another bloom filter by performing a bitwise OR of the
underlying data.
|
abstract boolean |
mightContain(Object item)
Returns
true if the element might have been put in this Bloom filter,
false if this is definitely not the case. |
abstract boolean |

writeTo(java.io.OutputStream out)
Writes out this
BloomFilter to an output stream in binary format. |

.
Ideally, this number should be close to the fpp
parameter passed in
create(long, double), or smaller. If it is significantly higher, it is usually
the case that too many items (more than expected) have been put in the BloomFilter
,
degenerating it.public abstract long bitSize()

"No!"
The fish says.
"Asleep! He probably won't wake up for a long time!" He says with glee.
You start to tell him that the fish is, in fact, awoken, but he cuts you off again.
"Even if he does wake up, he probably won't notice that his hat is gone."
At this, you glance back towards the big fish. You see him noticing that his hat is gone. Before you can say anything, the little fish distracts you.
