The derivative of a function of a real variable measures the sensitivity to change of the function value (output value) with respect to a change in its argument (input value). Derivatives are a fundamental tool of calculus. For example, the derivative of the position of a moving object with respect to time is the object's velocity: this measures how quickly the position of the object changes when time advances.
The derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point. The tangent line is the best linear approximation of the function near that input value. For this reason, the derivative is often described as the "instantaneous rate of change", the ratio of the instantaneous change in the dependent variable to that of the independent variable.
Differentiation is the action of computing a derivative. The derivative of a function \(y = f(x)\) of a variable x is a measure of the rate at which the value \(y\) of the function changes with respect to the change of the variable \(x\). It is called the derivative of f with respect to \(x\). If \(x\) and \(y\) are real numbers, and if the graph of \(f\) is plotted against \(x\), the derivative is the slope of this graph at each point.
When \(y\) is a linear function of \(x\), meaning that the graph of \(y\) is a line. In this case,\(y = f(x) = mx + b\), for real numbers \(m\) and \(b\), and the slope m is given by \(m={\frac {{\text{change in }}y}{{\text{change in }}x}}={\frac {\Delta y}{\Delta x}},\)
Let \(f\) be a function that has a derivative at every point in its domain. We can then define a function that maps every point \(x\) to the value of the derivative of \(f\) at \(x\). This function is written \(f′\) and is called the derivative function or the derivative of \(f\).
Let f be a differentiable function, and let \(f ′\) be its derivative. The derivative of \(f ′\) (if it has one) is written \(f ′′\) and is called the second derivative of \(f\). Similarly, the derivative of the second derivative, if it exists, is written \(f ′′′\) and is called the third derivative of \(f\). Continuing this process, one can define, if it exists, the \(n\) th derivative as the derivative of the \((n-1)\) th derivative. These repeated derivatives are called higher-order derivatives. The nth derivative is also called the derivative of order n.
The derivatives of a function f at a point x provide polynomial
approximations to that function near x. For example, if f is twice
differentiable, then
\(f(x+h)\) \(\approx\) \(f(x)+f'(x)h+{\tfrac {1}{2}}f''(x)h^{2}\)
in the sense that
\(\lim _{h\to 0}{\frac {f(x+h)-f(x)-f'(x)h-{\frac
{1}{2}}f''(x)h^{2}}{h^{2}}}\) \(=0\)

I Alone Level-up: Chapter 44
An eye watering smoke filled the room .
“cough, cough . ”
Yoo Jinho covered his face with a hand and coughed, but he was more worried about Jinwoo than himself . The lizardmen magician’s attack was dangerous, and his hyung appeared to have caught the brunt of it . Fortunately, Jinwoo appeared from the smoke, looking unharmed . Yoo Jinho was amazed,
‘Sasuga hyungnim!’
They say the lizardmen were one of the toughest magic beasts to face in a C-rank Dungeon, but Jinwoo had skillfully dodged a lizardmen magician’s attack without having a hair on him harmed . Somehow, it felt like the man was becoming faster everyday .
‘ . It can’t be, right?’
Jinwoo spat out small bits of rocks from his mouth .
“spit . ”
The spit on the ground was black .
‘These bastards…’
A mere lizardmen using paltry tricks forced him to breathe in some smoke . Jinwoo was annoyed by this, and it showed on his face .
| Bloodlust has been activated . . |
His wide open eyes radiated a powerful, murderous rage .
| Fear has been inflicted . . |
| The targets will lose 50% of all attributes for 1 minute . . |
The lizardmen hit with the bloodlust panicked .
“Ssuwack?” [1]
“Ssurukka?”
Jinwoo took advantage of the chaos and threw Casaka’s Poisoned Fang . The dagger flew in a straight line, right into the forehead of one of the lizard spearmen .
stab!
In their debuffed state, Jinwoo’s dagger was too fast to avoid .
“Ssukwa!”
Watching his comrade fall, the other lizard spearman roared with anger and thrust his spear . But his weapon struck nothing but air . Jinwoo had already disappeared into thin air .
“Ssurukahnakka!”
The lizardmen magician shouted with panic .
“Ssurukahnakka!!!”
As the magician repeated his words to the spearman, the warrior lizard turned to the magician and let out a beastly roar .
“Ssuukwa!”
The spearmen bared his teeth and approached the magician . The magician did not lose in fighting spirit .
“Sswarik!”
Suddenly .
“Kak!”
A hole appeared in the spearman’s chest . The blood spilled all over the magician, who took a step back in surprise .
“Ssuwak?”
shoooo-
As ‘Stealth’ was released, the spear that had pierced the lizard spearman’s chest showed its form . The hands wielding it belonged to Jinwoo . He let go of the weapon, and both it and the corpse stuck to it dropped to the ground .
thud
While the body fell, Jinwoo resummoned Casaka’s Poisoned Fang from the other corpse’s forehead back into his hand .
“Ssuwaaaaaarik!”
The lizardmen magician’s hands collected fire again . Jinwoo had no intentions of letting the thing annoy him again .
‘Sprint!’
The distance between him and the lizard shrank in an instant . The lizard magician’s eyes widened . Its reptilian eyes were rather unpleasant .
flaaare-
Jinwoo easily dodged its flames and appeared behind the magician’s back . Before the lizardman realized what happened, Casaka’s Poisoned Fang was sticking out of its spine .
‘Vital Stab!’
Stab!
The magician screamed .
“Kiaaaaaak!”
The second time it was stabbed, the scream was a lot shorter .
Stab!
“Kak!”
The lizardmen magician threw up blood and fell .
thud
In his head, Jinwoo pumped his fists . It was a clean fight .
‘Alrighty!’
As if congratulating him, the System’s electronic tone rang .
ring~
| You’ve leveled up!. |
| The ‘Player’ has reached a milestone level . [2]. |
A familiar message and an unfamiliar one .
‘A “milestone level”?’
At this point, Jinwoo had no idea what this meant . But reading the messages that followed, Jinwoo’s heartbeat raced to the point it was almost hurting . He had to spend some mental effort to try and calm himself .
ring~
| The Class Advancement Quest as arrived . [3]. |
| Would you like to accept? (Y/N). |
‘Class… Class Advancement Quest?’
Up until now, he had focused on his levels and stats and did not give much thought to a certain part of his status screen .
| Name: Sung Jinwoo. Level: 40 Class: None |
The third line of his status screen, “Class” .
‘If there is such a thing as Class Advancement Quest…’
Instead of “none”, it would finally be the opportunity to place a different word there .
He would obtain a class .
In most video games, the player character had a lot of choices in choosing their class . The System that operated like a video game should be the same .
BA DUM BA DUM
His heartbeat was roaring . In the face of another opportunity to become stronger, he could not calm himself .
| Would you like to accept?
‘Of course it’s yes…’
 Jinwoo prepared to accept the quest, but stopped instinctively .
‘Wait . ’
There was no knowing what kind of a quest he would receive . The instinctive hesitation was followed by a feeling of caution .
‘We’re inside a Dungeon right now . ’
They were in the most dangerous place in the world right now . Even if he had gotten used to the C-rank Dungeons, a Dungeon was a Dungeon . There was no need to ignorantly invite danger here .
On top of that, Yoo Jinho was also here . It wasn’t that he didn’t trust the young man . But there was no need to clue him in on the System or show him a strange phenomenon that may appear when he accepted the quest . Things might get complicated if he did .
‘Also, the quest might result in Jinho becoming hurt . ’
What if the quest suddenly spawned monsters?
‘Well, just that would be fine . ’
He just had to take them down as fast as possible . But from his experience, a mere monster hunting was not the limit of the quests . For example, the 2 emergency quests he had to complete .
‘This quest might tell me to kill the nearest Hunter next to me . ’
It was a faint possibility, probably not a realistic one, but Jinwoo was not about to risk it . While he was lost in thought, Yoo Jinho ran up to him .
“Hyungnim!”
It looked like the lizardmen magician’s last attack landed near the young man, his face was covered with soot and dust .
“I just saw you disappear and reappear! You had a skill like that?”
Despite of his dirtied face, Yoo Jinho’s eyes were sparkling with awe . It seemed that the young man was fascinated by seeing the rare skill .
‘I’m more fascinated by your face right now . ’
Instead of replying, Jinwoo took out a handkerchief from his inventory; it was one of the random items received from a daily quest .
“H-hyungnim?”
Jinwoo roughly wiped Yoo Jinho’s face with the handkerchief .
“Oof, mmph!”
The clean, white handkerchief quickly turned black . Jinwoo handed the item to Yoo Jinho . The young man looked at the dirty cloth and realized what his face was like . He walked away and quietly cleaned his face .
“Jinho . ”
“Yes, hyungnim . ”
“Something came up . ”
Yoo Jinho turned his face towards him with surprising alacrity .
“Do you have to go?”
“After finishing up here . ”
“I understand . I’ll cancel the reservation on the remaining Gates . ”
Yoo Jinho did not want to show Jinwoo his disappointment, but he deeply regretted the fact that they would have to give-up on the remaining 3 Gates .
‘I’m starting to run out of funds…’
To the young man who did not particularly have a source of income, the “funds” for his plan came from the allowance that he had saved up until now . Because he was acting without his father’s knowledge, he could not easily access the family’s money in his plan . If he cancelled the reservations, he would not be able to get the fees back . It would be money down the drain . Because of the unusual method in their Raiding, he had to spend a lot more than he had budgeted for . To think that he would be wasting the reservation fees for today… Yoo Jinho’s shoulders sunk .
But Jinwoo replied with a calm expression,
“Why would you cancel it? It’s so wasteful . ”
Yoo Jinho tilted his head in confusion .
“Hmm? If we reserve a Gate and not enter it in two days, the raiding rights are automatically forfeited, hyungnim . ”
Of course Jinwoo knew this basic fact of hunting .
“Leave it to me . ”
Did he have a plan?
Yoo Jinho was curious .
Baekho Guild Headquarters .
“Chief Ahn! Is your head on straight?!”
A loud berating was heard from the Second Management Division office . The owner of the voice was Baek Yoonho . He was Baekho’s Guildmaster, and the one who acted as the organization’s president . As often is the case, when someone who was basically the head of a company came down to a lower floor, it was not a good thing .
“What do you mean we still don’t have a Gate for new recruit training? We’ve already pushed the training back four days!”
The employees of the Second Management Division could not raise their eyes . They all looked away, hoping to avoid the Guildmaster’s wrath .
“ . ”
Unlike his subordinate Hyun Gicheol, Ahn Sangmin did not have the ability to skillfully steer the conversation to calm the wrath of the other person . In times like these, his best response was just to endure it with a closed mouth . Ignoring the man’s feelings, Baek Yoonho angrily waved the division’s report that had found its way to his desk this morning .
“What kind of an excuse is this?! Some other team was bidding too high, so we couldn’t reserve any? Is our Guild lacking funds? Is the other team some chaebol’s son?!”
Ahn Sangmin really, really, really wanted to speak up at that last sentence . But the man held his silence with an iron will . He remembered the promise with Jinwoo .
‘If I open my mouth now, the topic will naturally change to Yoo Jinho and Sung Jinwoo . ’
Not knowing just how much Ahn Sangmin’s insides were in turmoil, Baek Yoonho continued his shouting . The S-ranker’s roaring voice was enough to almost chase away the entire room .
 Do you understand?!”
It was in that moment .
Ahn Sangmin’s phone rang .
[Sorry I couldn’t pick up earlier~ I was meeting my friends~ shy shy shy~] [4]
He glanced at the caller and opened his eyes wide in surprise .
“Guildmaster, I have to pick this up . ”
“ . ”
Timing was the key to the main purpose of the Second Management Division: new recruit scouting . Ahn Sangmin was the boss of that division . No matter what kind of a mistake the man had made, it would be the height of foolishness to not let him do his job .
“Well? Pick it up . ”
Baek Yoonho gave a blunt permission .
Ahn Sangmin apologetically bowed his head to the Guildmaster then answered the phone .
“Hello, this is Baekho Guild’s Ahn Sangmin . ”
Baek Yoonho watched the man with his arms crossed .
“Yes, yes . I understand . I’ll come right over, please wait right there . ”
After hanging up, Ahn Sangmin immediately spoke up .
“Guildmaster, I have to leave on an urgent business . ”
The ace of the Second Management Division . If that Ahn Sangmin spoke of an “urgent business”, even in this situation where he was being berated… Baek Yoonho’s face relaxed ever so slightly .
“Is it related to new recruit scouting?”
“Yes, sir . ”
Looking at the man’s confident and determined face, Baek Yoonho realized something .
‘And the division chief himself is going?’
It meant that the target was not an ordinary Hunter . Baek Yoonho’s face that was filled with rage suddenly showed a smile .
“How could I stop the recruitment specialist from doing his job? Don’t worry about here and go . Do your thing . ”

Telecoms group Orange completes sale of Orange Niger arm to Zamani
PARIS (Reuters) - Orange, France’s biggest telecoms company, said it had completed the sale of its Orange Niger division to the Zamani Com SAS company, for an undisclosed value.
Orange’s operations in Niger have been hit by difficult market conditions and tax disputes with the Niger government.
Orange added in a statement on Friday that Africa and the Middle East nevertheless remained a key area for the company.

Remember Kottu? Those were the days. Anyway, Kottu has always been a totally open-source project, and theoretically it is as easy as cloning the git repo and... jumping a few hoops to set it up on your own local machine or VPS.
Except... the loops are tedious and there’s a bunch of things that could go wrong. There must be a better way, right?
Enter Docker. It promises to solve one of the oldest complaints in Computer Science, namely "it works on my machine". I’ve been using Docker at work for the past 6 months (hat tip to the wonderful Malitta Nanayakkara for getting me the job AND teaching me the basics of Docker) and my mind has been simply blown away by how simple and effective it is, and how I barely have to think about dependencies and reproducible environments anymore.
I won't get into the background of Docker and how it works, but there’s this wonderful series by Jeff Hale if you’re so inclined.
Step 1: Clone the Repo
It’s been almost over 2 years since I last messed with the Kottu source code, so it’s naturally no longer on my machine. I run a git clone and download the repo.
I look through the instructions and they basically go like “run kottu.sql on
the mysql server which you *obviously* have running on your machine
(#LAMPBoise
) and then copy this into your webroot, update the config, and bam!
Kottu for the whole kadey!”.
 I’m not even on Linux anymore! (the HORROR! 21 year old me writing Kottu would’ve spit in disgust if he knew I use a Mac now.)
Step 2: Look around the web for a docker-compose.yml file to hijack
No one writes software anymore, we just copy paste snippets from a thousand blog posts and StackOverflow answers, cobble it together, and pray it works.
I found two articles on this setup, one from DigitalOcean (excellent
resource) which is a bit Laravel-focused, and one from the
Geeky Platypus blog which was more generic. Kottu is custom PHP, and the
Geeky Platypus docker-compose.yml
file was cleaner, so I used it as the base
with some bits pulled from the DigitalOcean guide. Note that both use nginx and
not Apache because we’re civilised human beings nowadays.

Okay, there’s a bit to digest here:
We’re creating three services that work together, namely webserver, php and db.
The webserver is straight up garden variety nginx running on Alpine Linux, which
is very popular for Docker images because of the tiny size. It is exposing port
8000
(traditional Kottu port) on Localhost, and directing traffic from there
to the standard 80
port.
The root directory of the repo is being mounted on /var/www
, and a nginx conf
file we have inside our Docker folder is being set as the default.conf
for
nginx. More on this conf file (and networking) later.
The db service is based on a standard mysql 5.7
image1, exposing the
standard mysql port of 3306
, and with some env variables for setting the
database name and root password. We also mount a conf file and a data folder
so that database data is persisted across container restarts (internal container
data is by definition ephemeral, so if we don’t do this we will lose our data
if the container is ever down’d).
The php service also has the repo root mounted to /var/www
(so that that most
important mama of all files, index.php
can be accessed), but there are some
additional dependencies we want to install not included in the standard
php:5.6-fpm
image it is based on, so we include a custom Dockerfile
(more
on that later). The DigitalOcean guide has port 9000
being exposed by the php
container and everything, but I found that was unnecessary (and the Geeky
Platypus doesn’t use it either) so we don’t use that here.
Step 3: Networking
I’ve skipped talking about networking because networking in Docker deserves its own blog post, really. The example in the setup we have above, though, is a good starting point to talk about the amazeballs planet that is Docker networking.2
Now, it is standard knowledge that not all services should be exposed to the public internet. Ideally, we’d only expose things like SSH and the webserver to incoming traffic. Everything else traditionally sits behind a firewall. With this Docker Compose setup though, we have created two different networks which serve our purpose much better than any finicky firewall rules would.
Internet traffic can enter the default network and hence nginx, but it cannot enter the internal network.
In our dual-network setup, internet traffic can access nginx through the external (default) network (which uses the host driver, which allows it to bind directly to the Docker host’s network), but cannot access the internal bridge network. nginx, which sits on both the default and internal networks, can use the internal network to communicate with php and mysql.
Note that this works for HTTP traffic (as our nginx container only exposes port
80
), but on the server you might use something like
docker-letsencrypt-nginx-proxy-companion to make life easier (and support
HTTPS). It takes care of SSL certs and all that. You will have to replace the
default network in the compose file with the nginx-proxy network, attach the
webserver service to it, and add the VIRTUAL_HOST
, LETSENCRYPT_HOST
,
LETSENCRYPT_EMAIL
env variables to make proxy companion pick up the hostname
and the certificates you need.
Step 4: PHP Dockerfile
We need to install the mysql client and the PDO_Mysql
PHP extension on the php
service, so we’ll create a Dockerfile for that.
FROM php:5.6-fpm
# install dependencies
RUN apt-get update && apt-get install -y mysql-client
# install php extensions
RUN docker-php-ext-install pdo_mysql
I later found out that none of the images on Kottu were showing up and it’s because
Timthumb (yes, Kottu still uses Timthumb, please don’t hack us!) needs GD
, which
wasn’t installed. So let’s add those lines to the file too:
# Install GD and it's dependencies
RUN apt-get update && apt-get install -y \
libfreetype6-dev \
libjpeg62-turbo-dev \
libpng-dev \
&& docker-php-ext-install -j$(nproc) iconv \
&& docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
&& docker-php-ext-install -j$(nproc) gd
Step 5: The mysql and nginx conf files
my.cnf
is so basic that it doesn’t even deserve mentioning, but obviously you can
add more configurations here:
[mysqld]
general_log = 1
general_log_file = /var/lib/mysql/general.log
The site.conf
file for nginx is your standard nginx + php site config:
server {
listen 80;
index index.php index.html;
server_name localhost;
error_log /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;
root /var/www;
location / {
try_files $uri $uri/ /index.php;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass php:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
}
It tells nginx to listen for traffic on port 80, make /var/www
the web root, try to
find static files for the paths that visitors are trying to access, and then redirect
those requests to index.php
if that fails, and pass php requests to php:9000
(which
means port 9000
in the php service).
Step 6: Rock ’n’ Roll
We now get to say the magic words:
docker-compose up -d
Ah, satisfaction...
After the images and dependencies are downloaded and the containers are set up, a
docker ps
3 will reveal that three new containers have spun up and we’re ready
to roll. We direct our web browser to localhost:8000
, and...
Victo- oh god!
Whoops, we still need to import the database. But fear not, that’s pretty easy.
docker-compose exec php bash
root@3836dc148c6a:/var/www/html# cd ..
root@3836dc148c6a:/var/www# ls
LICENSE README.md cache config.php docker docker-compose.yml html img index.php kottu.sql lib static templates webcache
root@3836dc148c6a:/var/www# mysql -h db -u root -pyour_mysql_root_password kottu < kottu.sql
I just bash’d into the container, ran the mysql client4 (remember installing that
via the Dockerfile earlier?) and redirected kottu.sql
(which holds the database
schema) into it. Now, things still look empty but not broken:
Did you guys know that Flickr still exists?
Step 7: Add a blog and fetch its posts
Let’s go to the Kottu Baas admin interface, which most people haven’t seen.
Like all great login forms from 2012, the password is SHA-1 hashed on the clientside itself! SEKURITEEH.
After entering the default username/password combo of indi/indi, we are inside the uh-may-zin admin interface:
We click “add a blog” and a POPUP shows up! How wizard is that?
The copyright being stuck in 2012 is just apt!
In my bout of narcissism, I add my own blog and navigate to
localhost:8000/admin/feedget/<secretkey>
, and voila:
backendsecretkeywithunicorns! SEKURITEEH.
Aaaand, finally:
Even Timthumb works, uguise. :')
And there we have it. Now you’ve got your own piece of 2012 tech running a personalised version of Kottu on Docker! Next week, we cover how Kubern—5
* * *
Okay, this post isn’t the most comprehensible piece of writing I’ve done. It feels rushed and under-explained, and yet resulted in a very long post. The topics covered honestly require blog posts of their own, and time permitting, I would do one or two over the course of the year. But here’s a start. And it feels like a Friday night (and half of Saturday) well-spent setting up an ancient piece of code on Docker6, so that it becomes at least a tad more accessible.
I think I need to attach a fair warning: DON’T RUN THIS IN PROD, FOLKS. It’s from 2012 and has security holes the size of the Mariana Trench in it, and it’s a miracle that kottu.org still continues to run7.
-
Another really cool thing about Docker that I missed mentioning in the post is the ability to run different versions of, say, mysql or php (as your apps need them) on different containers. This is really helpful if you have a bunch of old code that can only run on an older version of php/python/whatever... ↩
-
Docker networking is seriously amazing, and they do things like adding iptables records to make it possible. I would recommend reading the Network section of the Docker docs. ↩
-
Docker has some really cool commands that help you administer everything. Some of my favourites are:
docker ps
— lists all the running containersdocker stats
— container statsdocker-compose logs -f
— logs from all the containers in the compose filedocker network ls
— lists networks ↩ -
A sharp-eyed reader might ask: "why not just run the mysql client from the
exec
command?". Well, I tried that and it gives some weird tty error that I remember once solving, but I forgot how. This bash/mysql method described here works without issue. ↩ -
This is a joke. I don't know Kubernetes. Who does, really?
¯\_(ツ)_/¯
↩ -
I updated the repo and its README with how to do a Docker setup! ↩
-
Hat tip to the mysterious maintainer who set up nginx and LetsEncrypt SSL certs on the Kottu server!


This is a polyfill of the defines-elements concept. When a script is declared to define types of elements those elements are hidden until the script has loaded.
If after the script had loaded, the element type is still not defined, an error is logged to the console to indicate to the developer that they failed to define the element.

Serves 2
Preheat the oven to 200C/390F/Gas 6. Place the black olive paste and bread into a food processor and blend for one minute. Spread the breadcrumb mixture onto a baking tray.
Transfer to the middle shelf of the oven and bake the crumbs for ten minutes, or until lightly toasted and dried out. Take care not to let them burn.
Lightly beat the egg whites in a small bowl. Season the lamb with salt and freshly ground black pepper. Dip the lamb in the egg white and then in the olive crumbs. Pat off any excess crumbs.
Place the olive oil and butter in an ovenproof frying pan. When the butter has melted, add the lamb to the pan and fry for one minute. Flip the lamb over and place in the oven. Roast for 20-25 minutes, or until just tender and golden-brown. Remove from the oven, cover with aluminium foil and leave to rest in a warm place.
For the sweet and sour aubergine, chop the aubergine into 2cm/¾in cubes and sprinkle with salt. Leave the aubergine for 15 minutes. The salt will release liquid from the aubergine, so you'll need to dab it dry with kitchen paper.
Add the olive oil to a frying pan. When the pan is hot, add the aubergine and fry for two minutes, before adding the celery and red pepper. Fry for three minutes.
Add the chopped tomato, honey and vinegar and simmer for a further ten minutes.
Add the capers, sultanas, pine nuts, chopped spring onions and basil to the pan and remove from the heat.
For the rocket dressing, place the rocket, olive oil and vinegar into a blender or food processor. Blend until smooth.
To serve, slice the lamb and spoon the sweet and sour aubergine onto two serving plates. Serve the slices of lamb on top of the aubergine and drizzle around the dressing.

BY EDWIN JAHIEL
CAN'T HARDLY WAIT * 1/2 Written and directed by Harry Elfont and Deborah Kaplan.Photography,Lloyd Ahern. Editing, Michael Jablow. Production design, Marcia Hinds-Johnson. Music, David Kitay & Matthew Sweet. Produced by Jenno Topping and Betty Thomas. Cast: Jennifer Love Hewitt (Amanda), Ethan Embry (Preston), Charlie Korsmo (William), Lauren Ambrose (Denise), Peter Facinelli (Mike), Seth Green (Kenny), Jerry O'Connell, (Trip McNeely), Jenna Elfman (Angel). A Columbia Pictures release. 95 min. PG-13
High-school kids are human, but you'd hardly think so from a large number of movies about them, including Can't Hardly Wait. It's the first directorial effort by Kaplan and Elfont whose main claim to fame was being among the five writers of A Very Brady Sequel.
A few teen films have been on the thoughtful side: the classic post-graduation American Graffiti, the excellent end-of-school-year Dazed and Confused (by Richard Linklater), some works by John Hughes (The Breakfast Club, Sixteen Candles), the funny-to-hilarious Fast Times at Ridgemont High (by Amy Heckerling), Ferris Bueller's Day Off, Weird Science (both by Hughes).
Note that the Hughes titles above were set in Illinois, while Dazed and Confused is in Texas. The school of the CHW kids is in California, the center of the universe as per Hollywood. The sad denial of another America beyond the southern Pacific coast continues, obviously for practical filmmaking reasons.
The opening credits are a quick, cutesy way to introduce the main characters, their accomplishments, aims, favorite quotes, etc. As a rule this gimmick makes one suspect the worst. One quote is "A true friend stabs you in the front," attributed to Oscar Wilde. I cannot guarantee its authenticity, but a search for it turned up a Wildeism more germane to the film: "There is no sin, except stupidity."
The film's title must refer to the impatience of the kids to leave adolescence for maturity, as well as to the state of English in schools. Following the seniors' graduation ceremony, their class has the usual ritualistic bash--in the home of a girl who ought to have known better than volunteer the place. The party is a rite of passage --not the Rites of Spring but the Trites of Spring. The motto, as in other such events, must be Brew and Screw.
For its characters, the filmmakers round up the usual suspects, all of them types found in the teen genre. If there is some originality here, it is well-hidden by cliches gathered from earlier flicks. CHW's deja vu types and actions make up a pot-pourri, an expression where "pourri" means "putrid." But this epithet would be too strong a condemnation of a movie whose main guilt is total superficiality.
The action almost entirely takes place at the shindig. Celebrants range from geeks to nerds to jocks to cuties. Without a central plot or guiding thread, the whole thing is just a collection of skin-deep subplots. The main one is this: athletic Mike, the BMOC, has just dumped Amanda, his girl since freshman class, as part of "game plan" with his pals. The idea is that those among them who are going on to college will have women by the regiment falling into their arms and beds, so why not break with the boys' current liaisons?
Learning this, college-bound would-be writer Preston wants to declare his love to now-uncommitted Amanda. He is a likable, shy fellow who has been adoring her silently ever since they both were freshmen. In a flashback to four years ago, the movie goofs by showing Amanda, Preston and others looking exactly as they do now. Add to this the sin that Hollywood has been committing since silent movie days and in many contemporary films as well: too many screen students --high-schoolers or undergraduates--are perceptibly older than they would be in real life.
Preston comes to the party with his confidante and best pal Denise. She is brainy a la Janeane Garofalo, even looks like a mix of Garofalo and a young Kathy Bates. She lacks confidence in her own appearance, is outside the girlish loop, critical of others, has a mordant tongue. Another subplot will involve her being accidentally locked inside a bathroom with Seth, with predictable consequences.  (There are, by the way, some merely token minority students at the party)
As for Amanda, she's been a kind of First Lady all along, Queen of this and of that. She is nice but, like almost everyone else, not a thinking person. (You wonder how the vague Preston will perform as a writer) Amanda does get the film' s main profundity when she realizes (and confesses a bit pathetically) that all her glory came from being Mike's satellite. With some people, it takes time to see the obvious.
I will not mention other characters, events or gratuitous developments of CHW. The partygoers, are without exception not just undeveloped but undersketched. There are few small saving graces. One is the movie's relative briefness. Even though the title calls for the joke I Could Hardly Wait For It To Finish, I did not find it unbearable -- just blah. Another is that Preston is neither depicted as pathologically shy nor as a caricature intellectual. There are no drop-dead gorgeous women. And, in a near-surreal sight, as Preston tries to use a public phone, a woman, a tired stripper with fake angel wings, hassles him for the use of the cabin. She is played by the uncredited Jenna Elfman, who recently had a major part in Krippendorf's Tribe and is married to the nephew of composer Danny Elfman.
Obviously made for high-schoolers who may or may not get some mini-shocks of recognition, and full of references to current pop culture, CHW will survive only if its target audience shows up.

The chapter is split into four sections and includes updated material to reflect the changes which have taken place since the first edition of the book was published. Part 1 outlines the origins and early development of the Internet. Part 2 considers its commercialisation through case histories of the key companies that emerged in its early history. Part 3 studies the associated stock market reaction, then the extraordinary bubble that ensued – and its aftermath. The final section looks at the wider impact of the Internet and how it may evolve in the future. This theme is also developed further in the final chapter.

Kanye West Performs Surprise Concert at Houston Jail
Ye and his choir gave a secret show at the Harris County Jail on Friday.
by Rebecca KimPrior to Kanye West’s largest anticipated Sunday Service at Lakewood Church, with an expected attendance of 45,000 people, the rapper stopped by the Harris County Jail in Houston for a surprise concert.
According to the Houston Chronicle, Ye and his choir arrived at the facility on Friday morning and held an intimate concert for nearly 200 people in the men’s jail. Then, the team went through the facility’s underground tunnel to perform a second show at the women’s jail.
The video above posted by the Harris County Sherriff’s Office shows Kanye meeting some of the inmates and staff, followed by a performance featuring songs from his recent Jesus Is King album. And in case anyone had any misconceptions about his appearance, he emphasizes that “this is a mission, not a show.”

Inventors are encouraged to search the USPTO's patent database to see if a patent has already been filed or granted that is similar to your patent. Patents may be searched in the USPTO Patent Full-Text and Image Database (PatFT). The USPTO houses full text for patents issued from 1976 to the present and PDF images for all patents from 1790 to the present.
All sequences (SEQ ID NOs.) and tables for listed patents or publications are available for viewing, without downloading, by accessing the proper document detail page and then submitting a SEQ ID NO or a mega table ID number.
Global Patent Search Network (GPSN) enables users to search the full text of multiple international patent collections. The initial collection available will be Chinese patent documentation from the State Intellectual Property Office (SIPO) of the People's Republic of China. Users can search published applications, granted patents and utility models from 1985 to 2012. The data available includes full text Chinese patents, English machine translations and full document images. This collection will be periodically updated to include additional years of coverage.
Customize a search on all or a selected group of elements (fields) of a patent.
The Patent Application Information Retrieval (PAIR) system provides IP customers a safe, simple, and secure way to retrieve and download information regarding patent application status.
To make it easier for any inventor to pursue patent protection in both the U.S. and Australia, USPTO Deputy Director Michelle K. Lee (right) and IP Australia Director General Patricia Kelly (left) signed Wednesday a Memorandum of Understanding strengthening their already solid partnership.
Patents may be searched in the USPTO Patent Full-Text and Image Database (PatFT).

Cheat Sheet¶
Version 3.15.3 for version 1.10 of the CF conventions.
This cheat sheet provides a summary of some key functions and methods in
cf-python (also available as a printable PDF for
pdf
).
Operation |
How to? |
|---|---|
|
Install cf-python, including any required dependencies, and the cf-plot visualisation package using pip: $ pip install cf-python cf-plot
|
Install cf-python with all of its required and optional dependencies, and the cf-plot visualisation package using conda: $ conda install -c conda-forge cf-python cf-plot udunits2 esmpy>=8.0.0
|
|
|
Import cf-python and cf-plot: >>> import cf
>>> import cfplot as cfp
|
|
Read the field constructs from a single file: >>> fl_1 = cf.read("file.nc")
>>> fl_2 = cf.read("umfile.pp")
|
Read the field constructs from two or more files: >>> fl = cf.read(['temperature.nc', 'precipitation_flux.nc'])
|
|
Read the field constructs using the * wildcard character (which reads all files in the directory that match the specified pattern): >>> fl = cf.read('~/file*.nc')
|
|
Return field constructs by selecting the elements of the resulting * wildcard file list: >>> fl = cf.read('~/file*.nc')[0:3]
>>> f = cf.read('~/file*nc')[-1]
|
|
Return field constructs whose identities match the given values: >>> fl = cf.read('~/file*.nc', select='units=hPa')
>>> fl = cf.read('~/file*.nc', select='air_temperature')
>>> fl = cf.read('~/cf-python/docs/source/sample_files/file*.nc', select='ncvar%q')
|
|
Selecting field: Select a field directly by index while reading the file: >>> temp = cf.read("file.nc")[0]
Select a field from a field list by identity: >>> temp = fl.select_field('air_temperature')
Select more than one field from a field list: >>> data = fl.select('long_name=precipitation', 'ncvar%stn')
|
|
|
Write one or more field constructs to a netCDF file: >>> cf.write(tas, 'temperature.nc')
|
Convert PP and UM fields files to netCDF files: >>> cf.write(pp, 'umfile1.nc')
|
|
|
Basic collapses: >>> min = f.collapse('minimum')
>>> v = f.collapse('variance')
>>> i = f.collapse('integral', measure=True)
|
Weighted collapses: Weighted time average: >>> avg = f.collapse('T: mean', weights=True)
Mean over the time and latitude axes, with weights only applied to the latitude axis: >>> mean_latitude = f.collapse('time: latitude: mean', weights='latitude')
Weighted area means: >>> mean = f.collapse('area: mean', weights=True)
|
|
Specifying Axes: Temporal maxima: >>> max = f.collapse('maximum', axes='T') # or equivalently:
>>> max = f.collapse('T: maximum')
Horizontal maximum: >>> max = f.collapse('maximum', axes=['X', 'Y']) # or equivalently:
>>> max = f.collapse('X: Y: maximum')
|
|
Grouped collapses: Annual maxima starting 1st December: >>> y_max = f.collapse('T: maximum', cf.Y(month=12))
December, January, February maxima: >>> djf_max = f.collapse('T: maximum', group=cf.djf())
Maxima for each 3-month season (DJF, MAM, JJA, SON): >>> seas_max_3 = f.collapse('T: maximum', group=cf.seasons())
Maxima for each 4-month season (JJAS, ONDJ, FMAM): >>> seas_max_4 = f.collapse('T: maximum', group=cf.seasons(3, 6))
Multiannual average of the seasonal means: >>> seas_avg = f.collapse('T: mean within years T: mean over years',
... within_years=cf.seasons(), weights=True)
|
|
|
Subspacing by index: >>> new = temp[:, :, 0]
>>> new = temp[0, [2, 3, 9], [4, 8]]
>>> new = temp[..., [True, False, True, True, False]]
|
Subspacing by metadata: Subspace to a new field construct whose ‘longitude’ coordinate spans only 45 degrees east, with the other domain axes remaining unchanged: >>> new = temp.subspace(longitude=45) # or equivalently:
>>> new = temp.subspace(X=45)
Subspace to a new field construct whose longitude coordinate is 45 degrees east and latitude coordinate is -60 degrees north, with the other domain axes remaining unchanged: >>> new = temp.subspace(X=45, Y=-60)
Subspace to a new field construct whose domain spans 34 to 72 degrees north and -25 to 45 degrees east: >>> new = temp.subspace(latitude=cf.wi(34, 72), longitude=cf.wi(-25, 45))
Subspaces based on the time dimension: >>> new = temp.subspace(T=cf.dt('1996-01-20'))
>>> jan_2023 = temp.subspace(T=cf.year(2023) & cf.month(1))

Regridding in spherical polar coordinates: Regrid observational data to that of the model data using bilinear interpolation: >>> obs_regrid = obs.regrids(model, method='linear')
Regrid observational data to that of the model data conservatively: >>> obs_regrid = obs.regrids(model, method='conservative')
Regrid observational data onto two-dimensional dimension coordinates latitude and longitude using bilinear interpolation: >>> import numpy
>>> domain = cf.Domain.create_regular((0, 360, 5.0), (-90, 90, 2.5))
>>> obs_regrid = obs.regrids(domain, method='linear')
|
Regridding in cartesian coordinates: Regrid the time axis ‘T’ of observational data with the linear method onto the grid specified in the dimension coordinate time: >>> time = cf.DimensionCoordinate.create_regular(
... (0.5, 60.5, 1),
... units=cf.Units("days since 1860-01-01", calendar="360_day"),
... standard_name="time",
... )
>>> obs_regrid = obs.regridc([time], axes='T', method='linear')
