UBC AeroDesign is an engineering student team that designs, builds, and flies heavy lift radio-controlled airplanes. Since 1992, the team has been building model aircrafts from scratch to compete in collegiate competitions organized by the Society of Automotive Engineers (SAE). The SAE Aero Design Series competition challenges university students from around the world to design and build a plane with the purpose of lifting the heaviest payload.
The two primary purposes of the team are:
UBC AeroDesign has grown into a diverse team composed of talented university students from all disciplines. The team’s passion for all things aerospace and desire to enrich student educational experience has pushed them to success. The team maintains a tradition of excellence: with over thirty teams participating in the SAE competition, the team has placed in the top ten, 20 times in its history.
Club members are free to explore their interests and encouraged to share their knowledge and skills with each other. As the team is entirely student led, senior members provide mentorship to new members. Junior members have the opportunity to specialize in areas like airfoils, engine and control systems, fuselage, structures and landing gear. In turn, senior members gain valuable project management skills and experience using the aircraft design process.
SAE Aero Design Series
The SAE Aero Design Series collegiate competition is intended to give undergraduate and graduate students experience working to solve real world engineering problems. At the root of this competition is a design challenge that UBC AeroDesign solves by performing trade studies and making compromises to reach the design solution that will optimally meet the mission requirement of lifting the heaviest payload, while still adhering to the configuration limitations.
UBC AeroDesign competes under Regular Class of the SAE Aero Design Series which is the event that draws the largest participation. In the past, the team has entered both the Eastern and the Western competitions. Each annual competition draws over 70 teams from all over the world and about 35 teams participate in Regular Class.
The objective of Regular Class is to design an aircraft that can lift as much weight as possible and to accurately predict the lifting capacity of the aircraft.
The Regular Class design has to follow the given requirements:
No lighter-than-air or rotary wing aircraft
An upper bound on the length + width + height dimension
A given payload bay volume
Single electric motor
1000 Watt power restriction
Limited takeoff and landing runway distance
Material restrictions (e.g. no Fiber-Reinforced Plastic)
The Regular Class is divided into the following assessment phases:
1. Technical ReportElectronic proposal submission for competition detailing how the design meets or exceeds the design requirements
Oral presentation given to SAE competition judges composed of engineers from companies like Lockheed Martin
Timed payload loading demonstration
Timed payload unloading demonstration
A final check to see if airplane meets design requirements and is in an airworthy state
Multiple rounds of flight and payload prediction
UBC AeroDesign is mainly composed of determined and driven undergraduate engineering students, but also includes students from other disciplines such as commerce and computer science. The most important skill UBC AeroDesign team members learn is the ability to work well in a team environment. Moreover, UBC AeroDesign is a place where team members can take classroom lessons and apply them in a practical manner.

SocketStream provides a stack of Connect HTTP middleware which is used internally to serve single-page clients, asset files and static files (e.g. images) in client/static
.
The Connect app
instance is accessible directly via the ss.http.middleware
variable within app.js
. The stack is loaded in this order:
Any prepended middleware is loaded here, then we load:
Any appended middleware is loaded here, then we load:
SocketStream allows you to prepend new middleware to the top of the stack (to be processed BEFORE SocketStream middleware) using:
ss.http.middleware.prepend()For example you could add:
ss.http.middleware.prepend( require('connect-winston')(winston) );
Because SocketStream adds connect.cookieParser()
and connect.session()
to the stack, if the middleware you're wanting to use requires sessions support (i.e. access to req.session
) it will need to be appended to the bottom of the stack AFTER SocketStream middleware has been loaded as so:
ss.http.middleware.append( everyauth.middleware() );Apart from determining where the middleware should be added, the
prepend()
and append()
functions work in exactly the same way as connect.use()
.
In order to avoid making repeated fs.readFile requests for serving static files, you can load Connect's 'connect-static' middleware, by passing this:
ss.http.set({ staticCache: { maxObjects: 128, // The number of objects to store in cache maxLength: 1024 * 256 // The file size limit for storing a file in cache, 256Kb } });
You can pass custom http middleware settings via ss.http.set
:
ss.http.set({ static: { maxAge: 30 * 24 * 60 * 60 * 1000 // cache static assets in the browser for 30 days }, staticCache: { maxObjects: 128, // The number of objects to store in cache maxLength: 1024 * 256 // The file size limit for storing a file in cache, 256Kb } });
At the moment, you can use this to set custom options for the following SS middleware:
We will find a way to make all of the middleware customisable in the near future.
Short of setting up your own middleware stack, you can pick a strategy other than the default. The minimal strategy will leave out session and compress middleware. So you will have to manage that yourself.
ss.http.set({ strategy: 'minimal' });
As an experimental feature you can set your own strategy. You can base it on the default strategy found in the source.
It can be configured by
ss.http.set({ strategy: require('./my.own.strategy') });

I think there might be something wrong with naming scopes with mutually inductive types - it seems impossible to pick one of its constructors as a case
in the type's own namespace:
mutual inductive foo, bar with foo: Type | FooA: foo | FooB: foo → foo with bar: Type | Bar: bar namespace foo #check FooB -- FooB : foo → foo #check foo.FooB -- FooB : foo → foo example (f: foo) : f = f := begin -- nevermind I'm proving f=f by cases, it's just an example cases f, case FooB { sorry }, /- invalid `case`, there is no goal tagged with prefix [FooB] state: 2 goals case foo.FooA ⊢ FooA = FooA case foo.FooB f : foo ⊢ FooB f = FooB f -/ case foo.FooB { sorry }, /- 'foo.FooB' is not a constructor state: 2 goals case foo.FooA ⊢ FooA = FooA case foo.FooB f : foo ⊢ FooB f = FooB f -/ end
I think the "foo.fooB is not a constructor" message is not very forward thinking
probably requires a patch to lean though
Yeah I think it's definitely broken. If I introduce a I can't reproduce this so possibly I made a mistake somewhere.notation ``FOOB`` := foo.FooB
before namespace Foo
and then use it inside in a function fn
within the namespace, unfold fn
stops working.

Sky of Green: Solar Explosions Create Aurora Borealis in Parts of US and Canada - Photos
For several hours, the unique astral display will be visible in the parts of the US and Canada that are located quite far from the polar regions of Earth - and that's before winter has even started!
A massive burst of solar energy that hit the planet earlier this week will cause Northern Lights to be seen in some parts of the United States and Canada, scholars announced on Wednesday.
"Weather permitting, highly active auroral displays will be visible overhead from Inuvik, Yellowknife, Rankin and Iqaluit to Juneau, Edmonton, Winnipeg, Thunder Bay and Sept-Iles, and visible low on the horizon from Seattle, Des Moines, Chicago, Cleveland, Boston, and Halifax", the University of Alaska-Fairbanks Geophysical Institute stated.
The Northern or polar lights can often be seen in the Arctic and Antarctic regions, as a result of powerful solar winds that cause disturbances in the atmosphere, hitting it with a flow of the electrically charged particles, and creating a colourful glow in the sky.

Noel McNamara staying on as Ireland under-20 head-coach
by Will O'CallaghanNoel McNamara has confirmed that he'll continue on as the head-coach of the Irish under-20 team for 2020, despite taking on the role of academy manager at Leinster.
He oversaw Ireland's Grand Slam success in last season's Six Nations and saw his injury-hit side finish eighth at the IRB World Rugby Championship before being appointed by Leinster.
“It’s a very exciting time,” McNamara told IrishRugby.ie ahead of his third campaign in charge of the Ireland 20s.
“Any opportunity you get to work with a national team, particularly young players, it’s always something that should be relished with great enthusiasm.
“This is our first time being based in the Sport Ireland Campus and I think it’s fair to say it’s a world-class facility and a huge addition to these players’ development and the player pathway. It’s just great to get started.”
He's also happy to juggle his two jobs in the coming months:
“There is obviously an overlap between the two and ultimately I think it’s an advantage being involved in the system and getting the opportunity to work with a national side and bench mark players against the best in the world.
“We’re really looking forward to the challenges that lie ahead.”
Everyone’s in the Team Of Us.
Vodafone. The Official Sponsor of the Irish Rugby Team.

based on the input parameters and get unique genes to plot. We choose the
genes that are identified as up-regulated only. As for the genes identified
as up-regulated for multiple clusters, we only keep the belonging towards the
one they have the highest Log2FC value.
In the heatmap, there will always be a cell annotation for the cluster
labeling used when finding the markers, and a feature annotation for which
cluster each gene belongs to. And by default we split the heatmap by these
two annotations. Additional legends can be added and the splitting can be

Download the Vivado HLx 2020.1: All OS installer Single-File Download to the docker-ubuntu-vivado directory (you will need an account).
The filename should be Xilinx_Unified_2020.1_0602_1208.tar.gz
and it
should be 36~GB (the Docker image is 109~GB so make sure you have enough
space in /var/lib/docker
.
Step 4 Build and test the Docker image
Follow the instructions in docker-ubuntu-vivado/README.md, i.e. type
docker image build -t vivado-2020.1 .
You can run using
docker run -e DISPLAY=`hostname`:0.0 -it --rm -v $PWD:/home/user/work -w /home/user vivado-2020.1
Step 5 Customise
In particular, you will probably want to edit Dockerfile and/or entrypoint.sh to include your licence files.
Step 6 File System (7/10/20)
By default, Docker puts its images in /var/lib/docker
. On most of my
machines I have a relatively small SSD for /
and use a larger hard disk
for /home
. Since the Xilinx tools take up 120 GB alone, I moved /var
, /home
and /opt
to the magnetic disk. Thus my /etc/fstab looks like
# mount the local HD to /home, /var and /opt
/dev/disk/by-uuid/HARD_DISK /srv/fs auto nodev,nofail,x-gvfs-show 0 0
/srv/fs/home /home none bind 0 0
/srv/fs/var /var none bind 0 0

X509V3_CONFIG
Section: OpenSSL (5)Updated: 2006-11-07
Index Return to Main Contents
NAME
x509v3_config - X509 V3 certificate extension configuration formatDESCRIPTION
Several of the OpenSSL utilities can add extensions to a certificate or certificate request based on the contents of a configuration file.Typically the application will contain an option to point to an extension section. Each line of the extension section takes the form:
extension_name=[critical,] extension_options
If critical is present then the extension will be critical.
The format of extension_options depends on the value of extension_name.
There are four main types of extension: string extensions, multi-valued extensions, raw and arbitrary extensions.
String extensions simply have a string which contains either the value itself or how it is obtained.
For example:
nsComment="This is a Comment"
Multi-valued extensions have a short form and a long form. The short form is a list of names and values:
basicConstraints=critical,CA:true,pathlen:1
The long form allows the values to be placed in a separate section:
basicConstraints=critical,@bs_section [bs_section] CA=true pathlen=1
Both forms are equivalent.
The syntax of raw extensions is governed by the extension code: it can for example contain data in multiple sections. The correct syntax to use is defined by the extension code itself: check out the certificate policies extension for an example.
If an extension type is unsupported then the arbitrary extension syntax must be used, see the ARBITRARY EXTENSIONS section for more details.
STANDARD EXTENSIONS
The following sections describe each supported extension in detail.Basic Constraints.
This is a multi valued extension which indicates whether a certificate is a CA certificate. The first (mandatory) name is CA followed by TRUE or FALSE. If CA is TRUE then an optional pathlen name followed by an non-negative value can be included.For example:
basicConstraints=CA:TRUE basicConstraints=CA:FALSE basicConstraints=critical,CA:TRUE, pathlen:0
A CA certificate must include the basicConstraints value with the CA field set to TRUE. An end user certificate must either set CA to FALSE or exclude the extension entirely. Some software may require the inclusion of basicConstraints with CA set to FALSE for end entity certificates.
The pathlen parameter indicates the maximum number of CAs that can appear below this one in a chain. So if you have a CA with a pathlen of zero it can only be used to sign end user certificates and not further CAs.
Key Usage.
Key usage is a multi valued extension consisting of a list of names of the permitted key usages.The supporte names are: digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment, keyAgreement, keyCertSign, cRLSign, encipherOnly and decipherOnly.
Examples:
keyUsage=digitalSignature, nonRepudiation keyUsage=critical, keyCertSign
Extended Key Usage.
This extensions consists of a list of usages indicating purposes for which the certificate public key can be used for,These can either be object short names of the dotted numerical form of OIDs. While any OID can be used only certain values make sense.
This is really a string extension and can take two possible values. Either the word hash which will automatically follow the guidelines in RFC3280 or a hex string giving the extension value to include. The use of the hex string is strongly discouraged.Example:
subjectKeyIdentifier=hash
Authority Key Identifier.
The authority key identifier extension permits two options. keyid and issuer: both can take the optional value ``always''.If the keyid option is present an attempt is made to copy the subject key identifier from the parent certificate. If the value ``always'' is present then an error is returned if the option fails.
The issuer option copies the issuer and serial number from the issuer certificate. This will only be done if the keyid option fails or is not included unless the ``always'' flag will always include the value.
Example:
authorityKeyIdentifier=keyid,issuer
Subject Alternative Name.
The subject alternative name extension allows various literal values to be included in the configuration file. These include email (an email address) URI a uniform resource indicator, DNS (a DNS domain name), RID (a registered ID: OBJECT IDENTIFIER), IP (an IP address), dirName (a distinguished name) and otherName.The email option include a special 'copy' value. This will automatically include and email addresses contained in the certificate subject name in the extension.
The IP address used in the IP options can be in either IPv4 or IPv6 format.
The value of dirName should point to a section containing the distinguished name to use as a set of name value pairs. Multi values AVAs can be formed by preceeding the name with a + character.
otherName can include arbitrary data associated with an OID: the value should be the OID followed by a semicolon and the content in standard ASN1_generate_nconf(3) format.
Examples:
subjectAltName=email:copy,email:my@other.address,URI:http://my.url.here/ subjectAltName=IP:<IP_ADDRESS> subjectAltName=IP:13::17 subjectAltName=email:my@other.address,RID:<IP_ADDRESS> subjectAltName=otherName:<IP_ADDRESS>;UTF8:some other identifier subjectAltName=dirName:dir_sect [dir_sect] C=UK O=My Organization OU=My Unit CN=My Name
Issuer Alternative Name.
The issuer alternative name option supports all the literal options of subject alternative name. It does not support the email:copy option because that would not make sense. It does support an additional issuer:copy option that will copy all the subject alternative name values from the issuer certificate (if possible).Example:
issuserAltName = issuer:copy
Authority Info Access.
The authority information access extension gives details about how to access certain information relating to the CA. Its syntax is accessOID;location where location has the same syntax as subject alternative name (except that email:copy is not supported). accessOID can be any valid OID but only certain values are meaningful, for example OCSP and caIssuers.Example:
authorityInfoAccess = OCSP;URI:http://ocsp.my.host/ authorityInfoAccess = caIssuers;URI:http://my.ca/ca.html
CRL distribution points.
This is a multi-valued extension whose options can be either in name:value pair using the same form as subject alternative name or a single value representing a section name containing all the distribution point fields.For a name:value pair a new DistributionPoint with the fullName field set to the given value both the cRLissuer and reasons fields are omitted in this case.
In the single option case the section indicated contains values for each field. In this section:
If the name is ``fullname'' the value field should contain the full name of the distribution point in the same format as subject alternative name.
If the name is ``relativename'' then the value field should contain a section name whose contents represent a DN fragment to be placed in this field.
The name ``CRLIssuer'' if present should contain a value for this field in subject alternative name format.
If the name is ``reasons'' the value field should consist of a comma separated field containing the reasons. Valid reasons are: ``keyCompromise'', ``CACompromise'', ``affiliationChanged'', ``superseded'', ``cessationOfOperation'', ``certificateHold'', ``privilegeWithdrawn'' and ``AACompromise''.
Simple examples:
crlDistributionPoints=URI:http://myhost.com/myca.crl crlDistributionPoints=URI:http://my.com/my.crl,URI:http://oth.com/my.crl
Full distribution point example:
crlDistributionPoints=crldp1_section [crldp1_section] fullname=URI:http://myhost.com/myca.crl CRLissuer=dirName:issuer_sect reasons=keyCompromise, CACompromise [issuer_sect] C=UK O=Organisation CN=Some Name
Issuing Distribution Point
This extension should only appear in CRLs. It is a multi valued extension whose syntax is similar to the ``section'' pointed to by the CRL distribution points extension with a few differences.The names ``reasons'' and ``CRLissuer'' are not recognized.
The name ``onlysomereasons'' is accepted which sets this field. The value is in the same format as the CRL distribution point ``reasons'' field.
The names ``onlyuser'', ``onlyCA'', ``onlyAA'' and ``indirectCRL'' are also accepted the values should be a boolean value (TRUE or FALSE) to indicate the value of the corresponding field.
Example:
issuingDistributionPoint=critical, @idp_section [idp_section] fullname=URI:http://myhost.com/myca.crl indirectCRL=TRUE onlysomereasons=keyCompromise, CACompromise [issuer_sect] C=UK O=Organisation CN=Some Name
Certificate Policies.
This is a raw extension. All the fields of this extension can be set by using the appropriate syntax.If you follow the PKIX recommendations and just using one OID then you just include the value of that OID. Multiple OIDs can be set separated by commas, for example:
certificatePolicies= <IP_ADDRESS>, <IP_ADDRESS>
If you wish to include qualifiers then the policy OID and qualifiers need to be specified in a separate section: this is done by using the @section syntax instead of a literal OID value.
The section referred to must include the policy OID using the name policyIdentifier, cPSuri qualifiers can be included using the syntax:
CPS.nnn=value
userNotice qualifiers can be set using the syntax:
userNotice.nnn=@notice
The value of the userNotice qualifier is specified in the relevant section. This section can include explicitText, organization and noticeNumbers options. explicitText and organization are text strings, noticeNumbers is a comma separated list of numbers. The organization and noticeNumbers options (if included) must BOTH be present. If you use the userNotice option with IE5 then you need the 'ia5org' option at the top level to modify the encoding: otherwise it will not be interpreted properly.
Example:
certificatePolicies=ia5org,<IP_ADDRESS>,<IP_ADDRESS>.8,@polsect [polsect] policyIdentifier = <IP_ADDRESS> CPS.1="http://my.host.name/" CPS.2="http://my.your.name/" userNotice.1=@notice [notice] explicitText="Explicit Text Here" organization="Organisation Name" noticeNumbers=1,2,3,4
The ia5org option changes the type of the organization field. In RFC2459 it can only be of type DisplayText. In RFC3280 IA5Strring is also permissible. Some software (for example some versions of MSIE) may require ia5org.
Policy Constraints
This is a multi-valued extension which consisting of the names requireExplicitPolicy or inhibitPolicyMapping and a non negative intger value. At least one component must be present.Example:
policyConstraints = requireExplicitPolicy:3
Inhibit Any Policy
This is a string extension whose value must be a non negative integer.Example:
inhibitAnyPolicy = 2
Name Constraints
The name constraints extension is a multi-valued extension. The name should begin with the word permitted or excluded followed by a ;. The rest of the name and the value follows the syntax of subjectAltName except email:copy is not supported and the IP form should consist of an IP addresses and subnet mask separated by a /.Examples:
nameConstraints=permitted;IP:<IP_ADDRESS>/<IP_ADDRESS> nameConstraints=permitted;email:.somedomain.com nameConstraints=excluded;email:.com issuingDistributionPoint = idp_section
OCSP No Check
The OCSP No Check extension is a string extension but its value is ignored.Example:
noCheck = ignored
DEPRECATED EXTENSIONS
The following extensions are non standard, Netscape specific and largely obsolete. Their use in new applications is discouraged.Netscape String extensions.
Netscape Comment (nsComment) is a string extension containing a comment which will be displayed when the certificate is viewed in some browsers.Example:
nsComment = "Some Random Comment"
Other supported extensions in this category are: nsBaseUrl, nsRevocationUrl, nsCaRevocationUrl, nsRenewalUrl, nsCaPolicyUrl and nsSslServerName.
Netscape Certificate Type
This is a multi-valued extensions which consists of a list of flags to be included. It was used to indicate the purposes for which a certificate could be used. The basicConstraints, keyUsage and extended key usage extensions are now used instead.Acceptable values for nsCertType are: client, server, email, objsign, reserved, sslCA, emailCA, objCA.
ARBITRARY EXTENSIONS
If an extension is not supported by the OpenSSL code then it must be encoded using the arbitrary extension format. It is also possible to use the arbitrary format for supported extensions. Extreme care should be taken to ensure that the data is formatted correctly for the given extension type.There are two ways to encode arbitrary extensions.
The first way is to use the word ASN1 followed by the extension content using the same syntax as ASN1_generate_nconf(3). For example:
<IP_ADDRESS>=critical,ASN1:UTF8String:Some random data <IP_ADDRESS>=ASN1:SEQUENCE:seq_sect [seq_sect] field1 = UTF8:field1 field2 = UTF8:field2
It is also possible to use the word DER to include the raw encoded data in any extension.
<IP_ADDRESS>=critical,DER:01:02:03:04 <IP_ADDRESS>=DER:01020304
The value following DER is a hex dump of the DER encoding of the extension Any extension can be placed in this form to override the default behaviour. For example:
basicConstraints=critical,DER:00:01:02:03
WARNING
There is no guarantee that a specific implementation will process a given extension. It may therefore be sometimes possible to use certificates for purposes prohibited by their extensions because a specific application does not recognize or honour the values of the relevant extensions.The DER and ASN1 options should be used with caution. It is possible to create totally invalid extensions if they are not used carefully.
NOTES
If an extension is multi-value and a field value must contain a comma the long form must be used otherwise the comma would be misinterpreted as a field separator. For example:
subjectAltName=URI:ldap://somehost.com/CN=foo,OU=bar
will produce an error but the equivalent form:
subjectAltName=@subject_alt_section [subject_alt_section] subjectAltName=URI:ldap://somehost.com/CN=foo,OU=bar
is valid.
Due to the behaviour of the OpenSSL conf library the same field name can only occur once in a section. This means that:
subjectAltName=@alt_section [alt_section] email=steve@here email=steve@there
will only recognize the last value. This can be worked around by using the form:
[alt_section] email.1=steve@here email.2=steve@there
HISTORY
The X509v3 extension code was first added to OpenSSL 0.9.2.Policy mappings, inhibit any policy and name constraints support was added in OpenSSL 0.9.8
The directoryName and otherName option as well as the ASN1 option for arbitrary extensions was added in OpenSSL 0.9.8

The ARM and MIPS models of the Sourcery Probe Personal support remote CDC Ethernet for TCP/IP communication over USB. This section describes how to configure the probe and Linux for use with USB.
Because the Sourcery Probe Personal models for PowerPC do not use TCP/IP communication, this section does not apply to those models.
The Linux kernel can assign different network interface names when you add or remove network interfaces.
Prerequisites
Before setting the PC’s network adapter static IP address, you must pick a suitable address. The address must be unique, but within the same range as the probe's address. New probes are configured for Local Link mode, which means the probe will assign itself an address in the range 169.254.xxx.yyy. You may want to check what value the probe picked using the Sourcery Probe Console, but in practice you can probably just pick any number from 1-254 for each of xxx and yyy. If the PC reports that the address you chose is already in use, then just try another value for xxx or yyy.
However, if the probe was reconfigured to use a static IP address, then you must pick an address within the range set in the probe. If the probe's IP address is unknown, you can find it by using the Sourcery Probe Personal Console Menu.

Sometimes people are so tense it doesn't take much to scare them. Cue either a smarty alec team-mate or a foe with the taste for irony simply stating "Boo". This results in the jittery character either freaking out or begin running in a panic while screaming. Usually a Comedy Trope but appears in genuinely scary works to show how threatening the monster/villain's presence is — especially if the monster/villain actually shows up soon afterward.
Compare Cherry Tapping which is a minor attack downing someone rather than a minor spook and The Last Straw.
Examples:
- In Episode 2 of the Little Lulu anime, Lulu says "Boo" to Tubby in a deadpan tone while pretending to be a monster, which sends Tubby running off screaming in terror.
- The Scarecrow pulls this on Judge Death in "Judgement on Gotham", a Batman/Judge Dredd crossover comics. Death is not amused...
- Christopher Champion (Tempest) pulls this on a guard at a museum where the Scanner One spaceship was stored in the Atari Force series.
- The first issue of the '80s-era Justice League features a terrorist attack on the U.N. General Assembly. As the spearhead of the Justice League's counterattack, Batman appears suddenly on the podium in front of the lead terrorist, whispering "Boo." Cue both terrorist freak-out and the rest of the League's Dynamic Entry.
- In Bloom County, wheelchair-bound Vietnam vet Cutter John is having tea with his girlfriend's mother. He asks if she's nervous, since some people are nervous around the handicapped. She, smiling, says no. Last panel is him saying "Boo." and her tossing her tea and shielding herself.
- In one Halloween comic strip of FoxTrot, Jason dresses up as a ghost and practices booing. The problem is that he's booing not like a ghost, but like a dissatisfied spectator.
- U.S. Acres: the original strip has an example of Roy trying this on Wade after tying his beak up.
- In Kage, Jade does this to Blunk when they first meet face-to-face.
- In The New Adventures of Invader Zim, Norlock pulls this on Dib when they meet for the first time after Norlock follows him and Zim back to Doomsville. He sneaks up on Dib at Parent Teacher Night and when Dib turns around and sees him, merely says "Boo". Dib ends up shrieking like a monkey and scuttling away.
- Shan-Yu greets the Emperor this way in Mulan. Played for scares, though the Emperor himself does not freak out.
- Space Jam, after the Nerdlucks transform into the Monstars.
- In Madagascar, after Alex fights off the fossa, he scares off the few that remain standing with a simple "boo".
- In Batman: Assault on Arkham, after escaping from his cell, The Joker simply walks out of the shadow toward a warden and says "Boo." This being The Joker, of course, the warden seriously freaks out.
- In Shrek, Shrek roars at an angry mob of would-be ogre hunters, who are left paralyzed with fear. When he subsequently whispers to them "This is the part where you run away," they finally run screaming.
- In Monsters University, a flat "boo" eliciting a scream from the simulator is what tips Mike off that there's something wrong with it.
- The live-action Casper movie has the clock strike 8 o'clock, showing Casper's a ghost. With a little "Um, boo?" the entire party flees Whipstaff Manor.
- How the Grinch Stole Christmas! has the titular character give a little "boo" when he shows up in Whoville to collect the Holiday Cheermeister award. The gathered crowd screams, which the Grinch responds to by saying "Hot crowd."
- Used by the Lunar Ghost in the first Scooby-Doo live-action movie. Naturally, Scooby screams.
- The Joker Pulls this on Vicki Vale in Batman (1989). Understandably, Vicki screams.
- Undercover Brother. When Lance gets into the limousine next to James Brown he's clearly nervous. James Brown says "Boo" to him and he almost jumps out of his skin.
- Played with in Ghost, where the title character freaks someone out by writing "BOO" on his mirror. Considering that Sam is, well, a ghost, and the person he's freaking out is watching the word trace itself into a fogged mirror, it's not really a "minor" scare at all.

- In A Nightmare on Elm Street (2010) (the remake), Nancy attempts to hide from Freddy while in the dream world. She hides in a closet, and for a moment it seems like it works, as Freddy scouts the room and leaves... only to appear in the closet beside Nancy and growl "Boo" in her ear. She naturally screams and runs out.
- In Pete's Dragon (1977), Elliot does this to Hoagy the second time they meet, when Hoagy comes to deliver the message that Pete's been captured.
- Marvel Cinematic Universe:
- In Doctor Strange, Christine gets a face full of the supernatural as she attempts to keep Strange alive while he battles a villain in the Astral Plane. After ghosts, poltergeist-like disruptions, and a magical portal in front of her very eyes, she's scared witless by a broom falling to the floor.
- Avengers: Endgame: After Tony Stark and Professor Hulk supervise the machinery assembling a new Infinity Gauntlet, and being understandably tense about it considering the power of the Infinity Stones they're manipulating, Rocket finds it funny to suddenly yell "BOOM!", making the two of them jump.
- The main character in Eden Green concentrates so hard on aiming her gun into the shadows, she doesn't notice the playful psychopath Tedrin sneaking up on her until he whispers, "Having fun yet?" This gets him shot.
- Mystery Science Theater 3000:
- When Mike and the 'Bots have The Screaming Skull inflicted upon them, Crow decides to pull a prank on Mike — dressing up as a skull and giving a feeble "raaar." The resultant meltdown by Mike has to be seen to be believed.
- Mike's on the giving end in another episode, wherein he scares away Krankor by muttering "Ahh."
- Bones: Temperance Brennan playfully says "Boo!"  It works.
- Monty Python's Flying Circus: A quick sketch featured a guy who from the 3/4 rear is opening his raincoat and appears to be flashing at passing ladies who are shocked and run off. He then turns to the camera and opens his raincoat to show he's fully clothed with a sign around his neck that says "Boo!"
- In Sesame Street's "News Flash" take on Little Miss Muffet, the spider appears to know this one.
- In Spyro 2: Ripto's Rage!, Ripto does this to Moneybags right after Moneybags said he'd give Ripto a piece of his mind if he was there.
- In Halo 2, the Master Chief does this after the Gravemind teleports him into High Charity and he finds himself standing right next to a very startled Grunt. The Grunt reacts by screaming in terror, throwing his gun, and running away. The MC then calmly grabs the gun and begins fighting his way through the Covenant capitol.
- Haunting Starring Polterguy: When the Sardini family's fear level is on high or very high, even less impressive fright 'ems will set them off and they look for a way to escape the house.
- RWBY Chibi: When Jaune is making an ASMR video, he doesn't notice Nora creep up behind him. She takes a deep breath as if she's about to yell in his ear, but instead very softly says "Hi". Jaune freaks out and jumps like cat in response.
- Variation in Brawl in the Family. Dedede and Meta Knight are stuck together by a Gooey Bomb and as Dedede is sweating Meta Knight flatly says "Boom" to get a rise out of Dedede.
- DM of the Rings attempts to have a spooky looking door as a cause of a paralyzing fear. The character overtly defies it, saying that it's simply a boring spooky door and nothing compared to his Call of Cthulhu campaign.
- Gunnerkrigg Court on page 153, when Mort tries to sneaks up on Kat and Annie sneaks up on him.
- In Punch an' Pie, Angela comes home to this when she meets Erik for the first time.
- In the Tex Avery cartoon "Slap-Happy Lion", a mouse scares a lion with a flat "boo". Doing it repeatedly drives the lion mad.
- Droopy, given his knack for Offscreen Teleportation, has done this a few times.
- Variant in 2 Stupid Dogs. The big dog will scare cats by going to up to them and giving a deadpan "Woof." The cat will then comically seize up in fear.
- In the U.S. Acres episode "I Like Having You Around", Wade tries to convince a bug that he's not afraid of him. However, the bug just says "Boo" to him in this manner, causing Wade to freak out and run in a panic.
- Raven does this to Beast Boy in an episode of Teen Titans.
- This was also exhibited in the first act of the Mr. Bogus episode "Bookstore Bogus" with a pair of ferocious worms that Bogus encounters in a book about bugs. When Bogus claims that he's not afraid of them, the worms look at each other for a few seconds before saying "boo" to Bogus in this manner, causing him to run in a panic with the worms hot on his tail.
- In a first season episode of The Venture Bros. 21 threatens Brock Samson with a lightsaber. After finding out the beam isn't solid, Brock leans in close and says "boo" making 21 run away. 3 seasons later after 21 Took a Level in Badass, Brock tries to do the same thing, and ends up getting round house kicked in the face.
- Chow does this to Tohru in Jackie Chan Adventures when he gets the first Oni Mask. Tohru, who has an immense fear of the Oni, freezes in terror before Jade tells him to snap out of it. Tohru later returns the favor when the mask is removed, and Chow flees with his tail between his legs.
- On one SpongeBob SquarePants, SpongeBob and Patrick claim that they weren't frightened by a scary movie. A flat "boo" from Squidward proves otherwise.
- In "Pranks a Lot", SpongeBob and Patrick accidentally turn themselves invisible and decide to have some fun by terrorizing all of Bikini Bottom as "ghosts." Mr. Krabs is the lone holdout who boasts of his fearlessness and kits himself up with various charms and an impromptu suit of armor to keep them at bay. Unsurprisingly, Patrick and SpongeBob make short work of these defenses, and once they disable his specter deflector (a paddleball), all it takes is a single "boo" to send him running for the door in a panic.
- An episode of the Beetlejuice cartoon has Lydia's friends look into the hollow of a tree they believe to be haunted. Beetlejuice calmly says, "Hey, how ya doin?" Lydia's friends flee in terror.

Our group from Old Miner finished up early, so most of us decided to check out Mount Moriah. Mount Moriah starts out with a rocky and muddy hill climb and continues on with some wicked off-camber sections. The hill climb isn't too tough, but the off-camber sections require careful driving.
After the off-camber secion, I was heading down a steep decent when smoke started pouring out of my dash. I jumped out of my Jeep with my fire extinguisher in hand. The smoke had a foul smell and seemed to be coming from my engine compartment. I struggled for what seemed like hours with my hood lock (I now leave a key in it when wheeling). By the time I got the hood open, the quantity of smoke was dropping. It seemed to be coming off my exhaust manifold and it didn't take me long to figure out that it was power steering fluid.  I was able to patch it with a spare hose clamp.
We continued on and stopped on top of of Strawberry Ridge for a look out over the Valley and the town of Deadwood. Behind Deadwood, we could see a gigantic mine. It turns out is the worlds largest open pit gold mine in the world, they just keep finding more gold there.
On the descent from Strawberry Ridge, we stopped at a memorial to Teddy Rosevelt. Our tail gunner, Douglas Jones, entertained us with some amusing ghost stories from the town of Deadwood and we jumped in our trucks to finished the decent into town. Another great day of four wheeling!

- Linking ambulance records to A&E records. https://ijpds.org/article/view/1104 The authors looked at the feasibility of conducting deterministic matching from ambulance records to A&E records without the use of patient identifiers. They only took one Trust in London, but the results look very promising. With ambulance records being notoriously difficult to link to because of no or limited patient details (difficult to collect data if the patient is unconscious), this is a potentially useful study. For us, it shows the importance of looking at combinations of data even if we don’t have what we want.

If we reassess the rationality question under the assumption that the uncertainty of the natural world is largely unquantifiable, where do we end up? In this article I argue that we arrive at a statistical, normative, and cognitive theory of ecological rationality. The main casualty of this rebuilding process is optimality. Once we view optimality as a formal implication of quantified uncertainty rather than an ecologically meaningful objective, the rationality question shifts from being axiomatic/probabilistic in nature to being algorithmic/predictive in nature. These distinct views on rationality mirror fundamental and long-standing divisions in statistics.
Brighton, H. (2019)
Ecological rationality provides an alternative to the view that rational responses to environmental uncertainty are optimal probabilistic responses. In this article I respond recent critiques by clarifying that ecological rationality is more than a set of algorithmic conjectures. It is also driven by statistical commitments governing the treatment of unquantifiable uncertainty.

Public risk perception of hazardous events such as contagious outbreaks, terrorist attacks, and climate change are difficult-to- anticipate social phenomena. It is unclear how risk information will spread through social networks, how laypeople influence each other, and what social dynamics generate public opinion. In this article we examine how messages detailing risks are transmitted from one person to another in experimental diffusion chains and how people influence each other as they propagate this information.

Surprisingly simple models sometimes predict more accurately than more complex, sophisticated models. Here, we address the question of when and why simple models succeed — or fail — by framing the forecasting problem in terms of the bias–variance dilemma. Controllable error in forecasting consists of two components, the “bias” and the “variance”. We argue that the benefits of simplicity are often overlooked because of a pervasive “bias bias”.

In contrast to the widely held view that less processing reduces accuracy, the study of heuristics shows that less information, com- putation, and time can in fact improve accuracy. We review the major progress made so far and argue that Homo heuristicus has a biased mind and ignores part of the available information, yet a biased mind can handle uncertainty more efficiently and robustly than an unbiased mind relying on more resource-intensive and general-purpose processing strategies.

We show how cultural selection for learnability during the process of linguistic evolution can be visualized using a simple iterated learning model. Computational models of linguistic evolution typically focus on the nature of, and conditions for, stable states. We take a novel approach and focus on understanding the process of linguistic evolution itself.
Brighton, H. & Kirby, S. (2006)
In this article we develop the theory that language codes information about it’s own structure, and as a result, languages themselves provide information that influences their own survival. To understand the consequences of this theory we discuss recent computational models of linguistic evolution. Linguistic evolution is the process by which languages themselves evolve.

Can machines really think? Is the mind just a complicated computer program? Introducing Artificial Intelligence focuses on the major issues behind one of the hardest scientific problems ever undertaken. Half a century of research into the construction of intelligent machinery has resulted in machines capable of beating the best human chess players and humanoid robots that can walk and interact with us. How exactly should we go about building an intelligent machine? Should it work like a mind? Should it work like a brain? Does it require a body?
Brighton, H., & Selina, H. (2003)
Knowledge of language is complex, yet the data available to the language learner are sparse. This incongruous situation, termed the “poverty of the stimulus,” is accounted for by placing much of the specification of language in the LAD. The assumption is that the characteristic structure of language is somehow coded genetically. The effect of language evolution on the cultural substrate, in the absence of genetic change, is not addressed by this explanation. We show that the poverty of the stimulus introduces a pressure for compositional language structure when we consider language evolution resulting from iterated observational learning.

'Immediate action required' from Nottinghamshire residents after serious flood alerts issued
The Government has warned that flooding is possible
by Hayley WatsonNottinghamshire residents should take 'immediate action' to protect their properties after serious flood warnings and alerts have been issued.
The Environment Agency has issued warnings and alerts for a number of locations along the River Trent, which is at risk of breaching its banks as a result of heavy rainfall this week.
A serious warning has been issued for the River Trent at Carlton-on-Trent, including Beck Cottage.
This reads: "River levels are rising at the Torksey river gauge as a result of high tides coinciding with high river levels.
"Consequently, flooding is expected on the high tide from 9am this morning and subsequent high tides until Friday. Areas most at risk are Carlton-on-Trent including Beck Cottage.
"Further rainfall is forecast for Thursday, 14/11/2019. We expect river levels to remain high until the weekend.
"Please move possessions and valuables off the ground or to safety and turn off gas, electricity and water."
Additional flood alerts - which means flooding is possible, but not expected - has been issued across Nottinghamshire.
Members of the public are advised to avoid using low lying footpaths near local watercourses and plan driving routes to avoid low lying roads near rivers, which may be flooded.
How to check for updates
The flood warning information service is closely monitoring the locations and will update the warnings as the situation changes.

At tracklist.me we believe that the artists should get 100% of the royalties generated by the sales of their music.
We do also believe that each artist should get the right amount of money they deserve from music streaming.
With less middlemen, music costs less for you and is more remunerative for the producers.
We do also think that artists should connect more with their fans. That's why we give you the opportunity to get all the useful information about your favorite artists, as well as special discount, limited edition material, and invitation to secret events.

DAY4 BATCH2 ASSIGNMENT
Q.3:Create an array of objects having the following parameters. A.{name(string),age(number),country(string),hobbies array(string[])} B. Write a function to dispaly all the objects on the console.


Problem 1. Planar coordinates Write functions for working with shapes in standard Planar coordinate system. Points are represented by coordinates P(X, Y) Lines are represented by two points, marking their beginning and ending L(P1(X1,Y1), P2(X2,Y2)) Calculate the distance between two points. Check if three segment lines can form a triangle. Problem 2. Remove elements Write a function that removes all elements with a given value. Attach it to the array type. Problem 3. Deep copy Write a function that makes a deep copy of an object. The function should work for both primitive and reference types. Problem 4. Has property Write a function that checks if a given object contains a given property. Problem 5. Youngest person Write a function that finds the youngest person in a given array of people and prints his/hers full name Each person has properties firstname, lastname and age. Problem 6. Group people Write a function that groups an array of people by age, first or last name. The function must return an associative array, with keys - the groups, and values - arrays with people in this groups Use function overloading (i.e. just one function)

The Law of Demeter is not really a law, but specifies a style guideline: never call a method on an object received from another call. The code that follows this guideline is easier to maintain, adapt, and refactor, has less coupling between methods, less duplication, and better information hiding. On the other hand, you may need to write many wrapper methods to meet this guideline.
Example:
boolean pay(Customer c, Invoice invoice) {
int dollars = c.getWallet().contents; // violation
if (dollars >= invoice.getAmount()) {
Wallet w = c.getWallet();
w.subtract(invoice.getAmount()); // violation
return true;
}
return false;
}
The above example might be better implemented as a method payInvoice(Invoice invoice)
in Customer
.
Use the Ignore calls to library methods and access to library fields option to ignore Law of Demeter violations that can't be fixed without changing a library.


Armageddon Review by Fox Davidson
In one of the most hyped films of the past decade, Armageddon is a mega-bust. A disaster flick that is a disaster on every level. Not even Bruce Willis can save this expensive, incoherent, derivative mess.
Following in the superior Deep Impact's heels, Armageddon tells the mudding tale of an asteroid the size of Texas on a collision course with Earth. The film fails to mention how this particular hunk of space rock was detected by NASA, or even the inept script-hole that shows a U.S. spacecraft being obliterated in orbit by a comet shower, followed by the destruction of Manhattan. Oops. NASA couldn't see that? I guess when you are Billy Bob Thornton (playing a NASA official), you kinda wonder how such a wonderful actor as yourself is reduced to rubish like Armageddon.
Willis plays Harry Stamper, "the world's best oil driller," who is called into action (just like it Die Hard, Mercury Rising, Die Hard 2!). I have no idea why Harry, and his retarted group of drillers, are called for a job that if failed, would mean the end of life as we know it.
The DVD of the movie is okay. It contains a trailer, I believe a commentary (I was so looking forward to taking this disc out of my machine, I didn't notice), and some other mumbo jumbo. The soundtrack is wide and good, but, like the cast, this disc is just worthless.

z-index
This is the default for a box-model element (not actually positioned) #### 2. Relative The element's position can be adjusted relative to its original location. #### 3. Absolute The rest of the page's elements do not affect this one. It is positioned based on the location of its nearest ancestor that is also positioned (ex: relative, absolute, fixed). If it can't find one, it is positioned relative to the <html>
document. #### 4. Fixed The element is flying solo. It's position is relative to the viewport and unaffected by other elements. #### 5. Sticky Element is relative until a condition is met. Then it becomes fixed to a page.
