For every specified requesting url, there are a set of contexts used to render its output.
Any variable with a '\$' token is meant to be replaced by its context value. Like the datetime below:
\${util.datetime} => ${util.datetime}
There are some predefined context for certain requests, and they are listed here
Here are more date examples below if you are really interested in it a lot.


This page contains a grab bag of various useful topics that don’t have an easy home elsewhere:
Ingress
Arbitrary extra code and configuration in jupyterhub_config.py
jupyterhub_config.py
Most people setting up JupyterHubs on popular public clouds should not have to use any of this information, but these topics are essential for more complex installations.
If you are using a Kubernetes Cluster that does not provide public IPs for services directly, you need to use a Kubernetes Ingress resource to get traffic into your JupyterHub. This varies wildly based on how your cluster was set up, which is why this is in the ‘Advanced’ section.
You can enable the required Ingress resources with the following in your config.yaml
config.yaml
ingress: enabled: true hosts: - <hostname>
You can specify multiple hosts that should be routed to the hub by listing them under ingress.hosts.
ingress.hosts
Note that you need to install and configure an Ingress controller for the ingress object to work.
We recommend the community-maintained nginx-ingress controller, kubernetes/ingress-nginx. Note that Nginx maintains two additional ingress controllers. For most use cases, we recommend the community maintained kubernetes/ingress-nginx since that is the ingress controller that the development team has the most experience using.
When using an ingress object, the default automatic HTTPS support does not work. To have automatic fetch and renewal of HTTPS certificates, you must set it up yourself.
Here’s a method that uses kube-lego to automatically fetch and renew HTTPS certificates from Let’s Encrypt. This approach with kube-lego and Let’s Encrypt currently only works with two ingress controllers: the community-maintained kubernetes/ingress-nginx and google cloud’s ingress controller.
Make sure that DNS is properly set up (configuration depends on the ingress controller you are using and how your cluster was set up). Accessing <hostname> from a browser should route traffic to the hub.
<hostname>
Install & configure kube-lego using the kube-lego helm-chart. Remember to change config.LEGO_EMAIL and config.LEGO_URL at the least.
config.LEGO_EMAIL
config.LEGO_URL
Add an annotation + TLS config to the ingress so kube-lego knows to get certificates for it:
ingress: annotations: kubernetes.io/tls-acme: "true" tls: - hosts: - <hostname> secretName: kubelego-tls-jupyterhub
This should provision a certificate, and keep renewing it whenever it gets close to expiry!
Sometimes the various options exposed via the helm-chart’s values.yaml is not enough, and you need to insert arbitrary extra code / config into jupyterhub_config.py. This is a valuable escape hatch for both prototyping new features that are not yet present in the helm-chart, and also for installation-specific customization that is not suited for upstreaming.
values.yaml
There are four properties you can set in your config.yaml to do this.
hub.extraConfig
The value specified for hub.extraConfig is evaluated as python code at the end of jupyterhub_config.py. You can do anything here since it is arbitrary Python Code. Some examples of things you can do:
Override various methods in the Spawner / Authenticator by subclassing them. For example, you can use this to pass authentication credentials for the user (such as GitHub OAuth tokens) to the environment. See the JupyterHub docs for an example.
Specify traitlets that take callables as values, allowing dynamic per-user configuration.
Set traitlets for JupyterHub / Spawner / Authenticator that are not currently supported in the helm chart
Unfortunately, you have to write your python in your YAML file. There’s no way to include a file in config.yaml.
You can specify hub.extraConfig as a raw string (remember to use the | for multi-line YAML strings):
|
hub: extraConfig: | import time c.Spawner.environment += { "CURRENT_TIME": str(time.time()) }
You can also specify hub.extraConfig as a dictionary, if you want to logically split your customizations. The code will be evaluated in alphabetical sorted order of the key.
hub: extraConfig: 00-first-config: | # some code 10-second-config: | # some other code
custom
The contents of values.yaml is passed through to the Hub image. You can access these values via the z2jh.get_config function, for further customization of the hub pod. Version 0.8 of the chart adds a top-level custom field for passing through additional configuration that you may use. It can be arbitrary YAML. You can use this to separate your code (which goes in hub.extraConfig) from your config (which should go in custom).
z2jh.get_config
For example, if you use the following snippet in your config.yaml file:
custom: myString: Hello! myList: - Item1 - Item2 myDict: key: value myLongString: | Line1 Line2
In your hub.extraConfig,
z2jh.get_config('custom.myString') will return a string "Hello!"
z2jh.get_config('custom.myString')
"Hello!"
z2jh.get_config('custom.myList') will return a list ["Item1", "Item2"]
z2jh.get_config('custom.myList')
["Item1", "Item2"]
z2jh.get_config('custom.myDict') will return a dict {"key": "value"}
z2jh.get_config('custom.myDict')
{"key": "value"}
z2jh.get_config('custom.myLongString') will return a string "Line1\nLine2"
z2jh.get_config('custom.myLongString')
"Line1\nLine2"
z2jh.get_config('custom.nonExistent') will return None (since you didn’t specify any value for nonExistent)
z2jh.get_config('custom.nonExistent')
None
nonExistent
z2jh.get_config('custom.myDefault', True) will return True, since that is specified as the second parameter (default)
z2jh.get_config('custom.myDefault', True)
True
You need to have a import z2jh at the top of your extraConfig for z2jh.get_config() to work.
import z2jh
extraConfig
z2jh.get_config()
Changed in version 0.8: hub.extraConfigMap used to be required for specifying additional values to pass, which was more restrictive. hub.extraConfigMap is deprecated in favor of the new top-level custom field, which allows fully arbitrary yaml.
hub.extraConfigMap
hub.extraEnv
This property takes a dictionary that is set as environment variables in the hub container. You can use this to either pass in additional config to code in your hub.extraConfig or set some hub parameters that are not settable by other means.
hub.extraContainers
A list of extra containers that are bundled alongside the hub container in the same pod. This is a common pattern in kubernetes that as a long list of cool use cases. Some example use cases are:
Database Proxies, which are sometimes required for the hub to talk to its configured database (in Google Cloud) for example
Servers / other daemons that are used by code in your hub.customConfig
hub.customConfig
The items in this list must be valid kubernetes container specifications.
By default, the hub’s sqlite-pvc setting will dynamically create a disk to store the sqlite database. It is possible to configure other storage classes under hub.db.pvc, but make sure to choose one that the hub can write quickly and safely to. Slow or higher latency storage classes can cause hub operations to lag which may ultimately lead to HTTP errors in user environments.

Oops, Amazon Just Dropped The Pixel 4 To Its Black Friday Price
It's about five days early, but Amazon has already dropped the price of the Pixel 4 to just $599, and the Pixel 4 XL to $699.  Which makes this a really great time to pick one up. As you are able to beat the rush and get yours now.
The Pixel 4 is the latest Pixel from Google. It comes running on Android 10 – the latest version of Android. It also has a new camera with a telephoto sensor, which can take some pretty incredible pictures. Though that's nothing new for Google and the Pixel.
With the new telephoto sensor, you're able to get even better zoom shots. Google is able to use some software magic to make zoomed in shots look better than cropped images.

Internally, both smartphones sport the Snapdragon 855 chipset, 6GB of RAM and 64GB of storage. The Pixel 4 has a 5.7-inch full HD+ display, with the Pixel 4 XL sporting a 6.3-inch Quad HD+ display. The only other difference between the two is the battery sizes, which are 2800mAh and 3700mAh capacities, respectively.
Google included Soli on these smartphones, which is radar. With this, you're going to be able to get some really great facial recognition, but there's also some cool features like being able to wave your hand over the phone and move to the next song, answer or decline a call and so on. It works really well, at least in my opinion.
The Pixel 4 is a really great smartphone to pick up, but it's not a no-compromise smartphone, as I said in our review of the Pixel 4 XL back in October. It does suffer on the battery side, but the Pixel 4 XL has less of a battery issue than the Pixel 4 does.

made the company review and change their process which brought more security to their employees and clients.
Describe how your culture has influenced your values and identity.
I grew up in a not so wealthy family during an economical crisis in Brazil.
This led my parents to work very hard to be able to provide the basic needs of the family.
My environment was based on hard work and creativity to make ends meet.
My parents decision to immigrate to another country to find work has been an shift in our lives.
We learned to adapt to many circumstances and to work even harder.
Although financial hardship was something present in our lives, my parents have always
managed to help others either by providing accommodation, help with work, food or income.
Today I have more empathy towards others and am always willing to help those in need.
Using the evidence gathered, describe your strengths and limitations.
Evaluate your strengths and limitations in terms of your learning and career development.
I'm a hard worker and very adaptable to different work environments. I'm open to new ideas and try

As per my limitation to open myself to others can be challenging to my colleagues as I will have
difficulty expressing my true feelings.
Identify which of your strengths might help you in your learning journey
and how they might intersect with learning obstacles.
I like to dig into the root of a problem to find a solution, which I believe will benefit my learning strategies.
Share an example from your experience of where you were trying to work productively with others,
but there was resistance or tension. Discuss the strategies you used at that time, how effective
they were, and your reflections on what other strategies you would try now, and why.
A colleague and I were trying to implement a new process in our workplace. The manager had assigned me
to run the new process and gave me the instructions. My colleague wasn't accepting the instructions given
and wanted to do it another way. After having little progress with the project, our manager had a meeting
with both of us and gave my colleague the same instructions I had been giving throughout the project.
After the meeting my colleague had no resistance and followed with the instructions correctly.
My colleauge's attitude made me feel insignificant at the time. However, today I realise I could've not been
clear with the instructions and should've asked my colleague for feedback.

- Module:
tar
- Published: October 7th 2021
- Reported by:
- CWE-22
- CVE-2021-37701
- Vulnerable: <4.4.16
- Patched: >=4.4.16
- Exploitability:
Overview
Impact
Arbitrary File Creation, Arbitrary File Overwrite, Arbitrary Code Execution
node-tar
aims to guarantee that any file whose location would be modified by a symbolic link is not extracted. This is, in part, achieved by ensuring that extracted directories are not symlinks. Additionally, in order to prevent unnecessary stat calls to determine whether a given path is a directory, paths are cached when directories are created.
This logic was insufficient when extracting tar files that contained both a directory and a symlink with the same name as the directory, where the symlink and directory names in the archive entry used backslashes as a path separator on posix systems. The cache checking logic used both \
and /
characters as path separators, however \
is a valid filename character on posix systems.
By first creating a directory, and then replacing that directory with a symlink, it was thus possible to bypass node-tar symlink checks on directories, essentially allowing an untrusted tar file to symlink into an arbitrary location and subsequently extracting arbitrary files into that location, thus allowing arbitrary file creation and overwrite.
Additionally, a similar confusion could arise on case-insensitive filesystems. If a tar archive contained a directory at FOO
, followed by a symbolic link named foo
, then on case-insensitive file systems, the creation of the symbolic link would remove the directory from the filesystem, but not from the internal directory cache, as it would not be treated as a cache hit. A subsequent file entry within the FOO
directory would then be placed in the target of the symbolic link, thinking that the directory had already been created.
These issues were addressed in releases 4.4.16, 5.0.8 and 6.1.7.
The v3 branch of node-tar
has been deprecated and did not receive patches for these issues. If you are still using a v3 release we recommend you update to a more recent version of node-tar
. If this is not possible, a workaround is available below.
Patches
4.4.16 || 5.0.8 || 6.1.7
Workarounds
Users may work around this vulnerability without upgrading by creating a custom filter method which prevents the extraction of symbolic links.
const tar = require('tar')
tar.x({
file: 'archive.tgz',
filter: (file, entry) => {
if (entry.type === 'SymbolicLink') {
return false
} else {
return true
}
}
})
Users are encouraged to upgrade to the latest patched versions, rather than attempt to sanitize tar input themselves.
Fix
The problem is addressed in the following ways:
- All paths are normalized to use
/
as a path separator, replacing \
with /
on Windows systems, and leaving \
intact in the path on posix systems. This is performed in depth, at every level of the program where paths are consumed.
- Directory cache pruning is performed case-insensitively. This may result in undue cache misses on case-sensitive file systems, but the performance impact is negligible.
Caveat
Note that this means that the entry
objects exposed in various parts of tar's API will now always use /
as a path separator, even on Windows systems. This is not expected to cause problems, as /
is a valid path separator on Windows systems, but may result in issues if entry.path
is compared against a path string coming from some other API such as fs.realpath()
or path.resolve()
.
Users are encouraged to always normalize paths using a well-tested method such as path.resolve()
before comparing paths to one another.

Keys was born Alicia Augello Cook on January 25, 1981, in the Hell's Kitchen area of Manhattan, in New York City.
 Keys' father is African American and her mother is of Italian, Scottish and Irish descent.
Keys has expressed that she was comfortable with her biracial heritage because she felt she was able to "relate to different cultures". Her parents separated when she was two and she was subsequently raised by her mother during her formative years in Hell's Kitchen, Manhattan. In 1985, Keys made an appearance on The Cosby Show at the age of four, where she and a group of girls played the parts of Rudy Huxtable's sleepover guests in the episode "Slumber Party".
Throughout her childhood, Keys was sent to music and dance classes by her mother. She studied classical piano from age seven playing composers such as Beethoven, Mozart, and Chopin, and enrolled in the Professional Performing Arts School at the age of 12, where she majored in choir and began writing songs at the age of 14. She graduated in four years as valedictorian at the age of 16.

PSYCHO (1960) Film Review by Ted Prigge Copyright 1998 Ted Prigge
Director: Alfred Hitchcock Writer: Joseph Stefano (based on the novel by Robert Bloch) Starring: Anthony Perkins, Janet Leigh, Vera Miles, John Gavin, Martin Balsam, John McIntire, Simon Oakland, Patricia Hitchcock, Virginia Gregg
I've seen "Psycho" about three times in my short lifetime, and I'm actually surprised how well it holds up even now. It's sad that many suspense films are so silly that you can't take them seriously, when at the same time, older films like this are almost as silly yet you can take them seriously. I'm not even sure how Hitchcock did it. Here's a flick where the protagonist of the film is killed off at the half-way point, and the supporting characters are left trying to find out what happens only to discover that one of the other main characters did it in drag. Looking at it like this, it seems so moronic that I can't believe I enjoy almost every minute of it. But that's the power of film, I guess.
"Psycho" is not the best film Alfred Hitchcock (who for my money is the greatest director who ever walked the face of this god forsaken planet) ever made, yet it's thought to be so by the general public. I think "Psycho" is definitely absolutely on Hitch's "Very Best" list, which includes such amazing films as "The 39 Steps," "Strangers on a Train," "Rear Window," and "Vertigo" (just to name a few). But it's just not his best. He's been better. But yeah, it's his most popular. Why is this?
It seems the answer to this is the infamous shower sequence, which is absolutely positively one of the 10 best-directed sequences I have ever seen on celluloid - there's no room for debate on this one. Hitch's editing, timing, everything has never been better on a scene, and just everything about it wreaks of greatness. But for me, at least, it's not why this film is just amazing. It's my favorite scene in the film, and yes, when I re-watched it on my birthday (the cool anniversary widescreen edition was one of my few birthday presents this year), I was blown away...and I rewatched it to see the editing and number of cuts, not just to see a glimpse of the supposed Janet Leigh nipple I've heard so much about. Honestly.
What makes this film so amazing for me is one thing: Anthony Perkins. I know that it's commonly said that Robert Walker's performance in "Strangers on a Train" is the best piece of acting in a Hithcock film - I mean, Nick Clooney has publically said that a couple times on AMC. But while his performance was brilliant in just the brilliance of it all, Perkins performance is brilliant because it gives us some sympathy...scratch that, a LOT of sympathy for the main subject of this film: Norman Bates.
 She starts on a paranoiac trek with the stolen money, and eventually winds up at a little middle-of-nowhere place, the Bates Motel. Too bad she didn't see the sequels first.
There, she befriends the lonely clerk, Norman Bates (Perkins), who lives in a giant, brooding house above the 12 rooms of the motel with his mother, whom we never see in these first scenes, but who's presence is made known in a couple scenes where she yells at Norman frantically.
The second half of the film (you didn't think it was all just the shower scene, did ya? seems that way sometimes) deals with Sam and Marion's sister, Lila (Vera Miles), trying to discover what has happened to her. We also get to meet a private investigator (Martin Balsam), hired by the men who's money was stolen by Marion, who tries to do some snooping around every motel and hotel in a million mile radius, but, unfortunately meets at a short, and untimely end. In this half, we also discover the BIG twist, which Hitchcock tried to keep secret back in '60, but asswholes like myself and the people who made the sequels have spoiled for those of you who have never seen it (shame on us!).
The film was an escape for Hitch, who's previous film was the amazing-as-hell "North By Northwest" (my favorite Hitch, and the single best "chase" movie I've ever seen). "Psycho" is grittier, less glamorous, and features no name actors (for the time). This probably gave Hitch an excuse to do some wildly experimental stuff with his directorial tactics, like giving us more gory death scenes, killing off the protagonist, using inner-voice dialogue weirdly (Marion imagines what her friends and co-workers will say when they discover what she's done), and also giving us a killer the likes of which had never been seen, and has rarely been copied since.
This is the thing that makes the movie. Sure, the entire film is an amazing display of great suspense tactics. I'm just freaked out during the whole beginning, where Marion tries to escape cleanly, but can't stop giving herself away to everyone she comes in contact with. Okay, I'm freaked out during the whole thing. Directing-wise, it's a masterpiece.
But these things would leave the viewer with a flat experience if it weren't for the way Hitch, his screenwriter Joseph Stefano, and his actor playing the role, Perkins, show Norman Bates off. He's the killer of this film. He's schizophrenic, divided between Norman and his mother. It's his portrayal of the Norman part, which dominates most of his screentime, which is so great. Norman is not a homicidal maniac. Nor is he a transvestite. He's a mild-mannered, sensitive, and despereately lonely person, reaching out for any signs of life he can reach, but keeps getting trapped by his other ego. Who knows? If he wasn't schizoid, he and Marion may have hit it off. But his other ego, afraid he'll lose him to another person, has Marion killed off quickly and in a grizly state.
It's an amazing thing watching Perkins do his schitck with the role. He inhabits him with so much sympathy and so much to like that when you find out he's really the killer, it's devastating. I mean, he's such a great person! Sure, sometimes he goes a tad off kilter, most notably when talking about his passion: stuffing birds. But Perkins cleverly plays him, showing off more to like but hiding some bits of darkness within. And this set of levels get dangerously out of whack as the film progresses.
It's this that makes "Psycho" such a great film. It's this that separates it from any other film about serial killers/homicidal nutcases. I have never seen a film before or since its release that has been so sad when its killer is revealed. Sure, it almost spoils the entire film by giving us a denouement featuring almost nothing but psych-talk (ugh), but just fast-forward through that scene if you've already seen it, and watch that final scene with Norman in the chair with the blanket, with a voice over by his mother's ego (voice by an uncredited Virginia Gregg). The film quickly redeems itself from a final scene where those in the audience that didn't catch it the first time that Norman is crazy can have it fed to them on a spoon (I wouldn't be shocked at all if he didn't have some sort of fit with the distributors).
Never mind the shower scene. Or the big twist. Or even the paranoid beginning.  The reason this film is so amazing, why I think it's one of Hitch's "Very Best," is because of Norman Bates, and how he's portrayed. He makes the whole thing real. He's the real reason this is an amazing film, not because for two minutes, you get to see a perfectly filmed murder sequence. Although that scene's good for other reasons.
MY RATING (out of 4): ****
