I'm learning about logic by going through the excellent Stanford Introduction to Logic, as part of writing a maths tutorial. Here I'm working through Exercise 3.4 - Propositional Entailment. Let me know if you disagree with any of my answers:
Let Γ and Δ be sets of sentences in Propositional Logic, and let φ and ψ be individual sentences in Propositional Logic. State whether each of the following statements is true or false.
a. If Γ ⊨ φ and Δ ⊨ φ, then Γ ∩ Δ ⊨ φ.
I'll show it's false by providing a counterexample. If P is an atomic formula:
Γ = {(P and not P), P}
Δ = {(φ and not φ), P}
Since Γ and Δ contain an unsatisfiable formula they entail everything, so Γ ⊨ φ and Δ ⊨ φ are both true. Also:
Γ ∩ Δ = {P}
The formula (P implies φ) is not valid, and so it's false that Γ ∩ Δ ⊨ φ.
b. If Γ ⊨ φ and Δ ⊨ φ, then Γ ∪ Δ ⊨ φ.
If Γ = {P1, P2, P3, ...} then:
(P1 and P2 and P3 and ...) implies φ
is valid. If Δ = {Q1, Q2, Q3, ...}
(P1 and P2 and P3 and ...) and (Q1 and Q2 and Q3 and ...) implies φ
must also be valid since for any interpretation, adding more 'and' terms to a formula can never make it true if it was false. If adding the Q terms only introduces false interpretations on the left hand side of the 'implies' then the whole formula will remain valid. So:
Γ ∩ Δ ⊨ φ
is true.
c. If Γ ⊨ φ and Δ ⊭ φ, then Γ ∪ Δ ⊨ φ.
Using the same reasoning as above, if:
Γ = {P1, P2, P3, ...}
then:
(P1 and P2 and P3 and ...) implies φ
is valid. If:
Δ = {Q1, Q2, Q3, ...}
then:
(P1 and P2 and P3 and ...) and (Q1 and Q2 and Q3 and ...) implies φ
must also be valid since for any interpretation, adding more 'and' terms to a formula can never make it true if it was false. If adding the Q terms only introduces false interpretations on the left hand side of the 'implies' then the whole formula will remain valid. So:
Γ ∪ Δ ⊨ φ
is true.
d. If Γ ⊭ ψ, then Γ ⊨ ¬ψ.
If:
Γ = {P1, P2, P3, ...}
then if Γ ⊭ ψ then:
(P1 and P2 and P3 and ...) implies ψ
is not valid.
then by the unsatisfiability theorem:
P1 and P2 and P3 and ... and ψ
is unsatisfiable.
e. If Γ ⊨ ¬ψ, then Γ ⊭ ψ.
Using proof by counterexample. If:
Γ = {(ψ and not ψ)} then:
(ψ and not ψ) implies ¬ψ
is valid, because (ψ and not ψ) is unsatisfiable. So:
(ψ and not ψ) implies ψ
is also valid. And so:
Γ ⊨ ψ
is true, which means:
Γ ⊭ ψ
is false.


We wish to travel from some departure airport to a destination airport such that we will arrive at the destination the at the earliest possible time. The direct path (if there is one) might not give the earliest arrival time, so the solution will probably be a multi-legged itinerary. There is a minimum layover time at every intermediate airport which must be factored into the scheduling.
We also wish to know, for our chosen itinerary, the total time enroute (difference between departure time of the first flight and arrival time of the last flight), the total in-flight time, and the total layover time. The enroute time should equal inflight time plus layover time.
Write a program called
find_itinerary
.
Flight data will be read from standard input and the origin and
destination airports shall be command-line arguments
argv[1]
(origin)
and
argv[2]
(destination).
Write a separate stand-alone program
flight_summary
that takes the output of
find_itinerary
and produces the summary statistics enroute time, in-flight time,
and layover time.
Solve the problem using Dijkstra's Shortest Path algorithm. Represent the network of flights as a directed graph. Use an edge list, not an adjacency matrix.
Assume the minimum layover is 1 hour. Define this as a class (static) variable so that an API might be added in some future release to allow runtime control of this parameter.
Each node is represented by an airport identifier (three- or four-letter airport code). Assume that some other part of the hypothetical system keeps data associating the identifier with the city and airport name to provide for readable output.
Time values are a (decimal) numeric value dddhhmm where ddd is the day of the year (1-365), hh is the hour (24-hour clock, midnight is 00) and mm is the minute (0-59). As a simplifying assumption, we won't deal with the year-end wrap-around. Do not hesitate to convert this value to some more-convenient internal format.
Each edge contains a set of flights, each with its departure and arrival time.
The input file consistes of one-line records, each record containing for tab-separated fields:
There is no need to represent the airports (nodes) in the input file: it can be generated from the edge list.
The output will be a list of flights in the same format as the input.

Determine them yourself. Think about reasonable subproblems that you could build and test separately.
Use
std::map
only
for building the graph from the file.
Use
std::vector
to hold the edge list.
Note that the STL
priority_queue
class is missing the
decrease_key
operation required by Dijkstra's algorithm, so you couldn't use it
even if it were permitted.
Flight data has absolute start and end times which we will wish to compare. We will also wish to compute time differences (relative time or interval). Thes are two logical candidates for distinct classes.
The constructor for the absolute time class should take a
dddhhmm
value as argument. You probably want to implement comparison
operators.
The constructor for the relative time class should take two absolute time objects and compute their difference. You probably want to implement a sum method.
You may or may not want to implement other constructors and/or methods.
Since the output format of
find_itinerary
conventiently matches its input format, you should be able to
reuse your input and time routines in
flight_summary
.
Here are some Washington State airports with selected distances between them (in nautical miles). You may use this graph to produce your flight data, or generate data on your own.
People select flights not only by arrival time. Modify your program so it takes an additional command-line argument which may be one of the following tokens:
ARRIVAL
: find the itinerary with earliest arrival
time
ENROUTE
: find the itinerary with the minimum total
time enroute (in-flight plus layover time).
INFLIGHT
: find the itinerary with minimum total
time in flight
LAYOVER
: find the itinerary with minimum total time
spent waiting around an airport
Most people also specify an earliest departure time.
If you've done things right, these should be a relatively small changes to your code.

Like many african communities, naming children is not done randomly.Names are chosen arcording to gender, time of birth, place of birth or basically anything that can influence
Akan names are derived from Ghanian culture. Frequently in Ghana, children are given their first name as a 'day name' which corresponds to the day in the week they were born.

by None at 2021-08-13 12:52:37.Since this is item information can it be added as an attribute in the holdings1_display like we do for 876$zxh ? Do we need a new field? @kevinreiss
We should add a new field to the item level data that makes it into the solr doc that reside in holdings1_display for the SCSB records. The 876 is intended to represent data at the item so even though it may seem a bit repetitive I think it's best to keep it there in our JSON data alongside the other item-level attributes like barcode, collection group designation, and use restrictions.
Ok so my understanding is that we don't need an extra solr field. Only to include it in the holdings_1display field and only for scsb.

by Cliff Wulfman at 2021-08-13 13:03:34.I'm not sure. I think @jpstroop would know maybe? Most of these tickets were just migrated from the spreadsheet.
The Friends paid to have this digitized but wanted a JStor-like interface so we, erm, gave derivatives to JStor. These are the master archival files and we need to keep them because JStor, iirc, only has relatively small JPEGs and isn't really a repository.
(to answer @kelea99's question: they were never public anywhere else digitally)
Thanks, @jpstroop . If our intent is to keep the entire digitized run eternally dark and have them in Figgy for preservation reasons alone, I wonder if Figgy is the right place for them. If it is, maybe we should discuss adding a visibility indicator for such things that are to remain dark in Figgy (other than Private). @escowles I think the MVW ingest would work fine if we are only preserving them in Figgy. If we want to make stuff available to users, the User Experience for the MVW in our catalog should probably be tested and discussed (think Trentonian). All of these appear to be open access on JSTOR, but if we decided to make the high resolution versions available at some point via figgy, the MVW access is currently an all or nothing setting - they would all be open, or they would all be CDL (due to copyright) and physical items would need to be sequestered.
@kelea99 I think it's fine to ingest them as Private — corner cases like this are the main reason that Visibility and Rights are separate fields. And I agree that ingesting as one big MVW is fine for this purpose, but would be trouble if we wanted to make them accessible.
@roelmoon and @jpstroop there are two (duplicate?) directories for PUDL0138. I'm currently ingesting from pudl=>pudl0138_LibraryChronicle for both bibs (2863923 and 426209). Figgy Collection: Biblia and PUL Chronicle (Keep Dark)
Directories are not duplicates.
There should be 76 volumes in<PHONE_NUMBER>06421 . issues also do not match up. Will continue ingesting from pudl=>pudl0138_LibraryChronicle.
pudl=>pudl0138 is definitely incomplete and contains fewer volumes, but unclear if everything in pudl0138 is duplicated in pudl0138_LibraryChronicle.
Keeping both for time being.

what is pudl 0062 backup versus 0062
MC205 needs to be migrated. KEL contacting alexis a about this one. We should probably move things from MC205 from PUDL 0062 to Archives share, like the others (MC205 is the only remaining sub directory with images in that PUDL collection, other than the csvs).

More and more tests are failing while Figgy's converting IDs, we'll have to take care of this next week.
This should have the Vagrant configuration removed, as testing this is cumbersome.

This nursery pud is a classic, and a great way to turn some leftover bread and a few storecupboard staples into a real treat.
Equipment and preparation: for this recipe you will need six ramekins or individual heatproof glass dishes, 10cm/4in in diameter.
Preheat your oven to 180C/350F/Gas 4. Butter six ramekins or individual heatproof glass dishes, 10cm/4in in diameter.
Divide the breadcrumbs between the ramekins, scattering them evenly.
Put the milk in a saucepan. Add both the vanilla seeds and pod to the saucepan. Slowly bring the milk just to the boil, then remove from the heat.
Whisk the sugar, egg and egg yolks together in a bowl. Pour on the hot milk and whisk well. Strain this into a jug.
Pour the custard into the prepared dishes, dividing it equally.
Stand the dishes in a large roasting dish. Pour enough hot water into the roasting tin to come about halfway up the sides of the ramekins. Bake in the oven for 25–30 minutes, or until the custards are set. Remove from the roasting tin and allow to cool. Discard the hot water. Return the ramekins to the emptied out roasting tin.
If your jam is very stiff, beat it to soften, or heat it slightly. When the custards are cool, spread the jam over them.
For the meringue topping, whisk the egg whites with an electric whisk, or using a freestanding mixer with a whisk attachment, until they hold stiff peaks when the whisk is removed. Beat in the sugar a spoonful at a time, until you have a fluffy meringue that holds stiff peaks when the whisk is removed.
Spoon the meringue into a piping bag fitted with a 1cm/½in nozzle and pipe it on top of the jam-topped custards. Bake for 10–15 minutes, until the meringue is light golden-brown. Serve immediately.


A2ML - Automation of AutoML¶
The A2ML ("Automate AutoML") project is a Python API and set of command line tools to automate Automated Machine Learning tools from multiple vendors. The intention is to provide a common API for all Cloud-oriented AutoML vendors. Data scientists can then train their datasets against multiple AutoML models to get the best possible predictive model. May the best "algorithm/hyperparameter search" win.
The PREDIT Pipeline¶
Every AutoML vendor has their own API to manage the datasets and create and manage predictive models. They are similar but not identical APIs. But they share a common set of stages:
Importing data for training
Train models with multiple algorithms and hyperparameters
Evaluate model performance and choose one or more for deployment
Deploy selected models
Predict results with new data against deployed models
Review performance of deployed models
Since ITEDPR is hard to remember we refer to this pipeline by its conveniently mnemonic anagram: "PREDIT" (French for "predict"). The A2ML project provides classes which implement this pipeline for various Cloud AutoML providers and a command line interface that invokes stages of the pipeline.

Welcome to the section that really makes this book unique. In my opinion, one of the best ways to prepare for the DB2 9 Fundamentals certification exam (Exam 730) is by answering sample questions that are presented in the same format that you will see when you take the certification exam. In this section you will find 150 sample questions, along with comprehensive answers for every question. (It's not enough to know which answer is correct; it's also important to know why the answer is correct and why the other choices are wrong!)
If you worked through the Practice Questions presented at the end of each chapter, many of these questions will be familiar; if you skipped that part, all of those questions can be found here, along with many new ones. All of the questions presented here were developed by analyzing the final set of questions that were chosen for the DB2 9 Fundamentals certification exam (Exam 730). (I was a member of the team that developed the DB2 9 Fundamentals certification exam so I had access to every question!) I hope you find this material helpful.
-Roger E. Sanders

The minimum age to rent a vehicle with Keva Auto Rentals LLC is 20 years old throughout the U.S. and Canada, and 18 years old in New York and Michigan.
Yes. Renting a car at age 18 is possible in a few specific instances. See below.
• U.S. Government Exceptions: If someone is a United States military personnel or Government Employee and can provide official government paperwork to the rental location in which they are inquiring, they will be able to rent a car at age 18.
A Young Renter Fee (also called an Age Differential Charge or Underage Driver’s Fee) is an additional fee that is applied along with the standard car rental rate to reservations of drivers ages 20-24.
Keva Auto Rentals LLC car renters who are ages 20 years old and up can rent most classes of vehicles, except certain specialty car classes.
The National Highway Traffic Safety Administration reports that drivers under the age of 25 are statistically more likely to be involved in auto accidents than drivers who are over the age of 25. Statistics of auto accidents involving drivers ages 25 and up are dramatically lower than the accident rates of young drivers.
However, safe and qualifying drivers who are between the ages of 20 and 24 (or ages 18-24 in Michigan and New York) are able to rent cars with Keva Auto Rentals LLC. In order to do so, young renters will be subject to a Young Renter Fee.
The minimum age to rent a vehicle is 21 years of age. There is no maximum restriction in the United States and Canada. See Exceptions below.
• A 'Young Renter Fee' may be applied to your rental, if you are between the ages of 21 and 24.
• The average cost is approximately $20.00 per day but can be higher or lower
Generally, coverage from your primary auto insurance will extend to a rental vehicle. If you cause an accident while driving the rental, your liability insurance would pay up to your policy limits for the damages to other cars or property.
The collision damage waiver, also known as optional vehicle protection or loss damage waiver, can cost as much as $19 per day and shifts liability for collision damage from the person renting the car to the company. However, your personal auto insurance should already include liability insurance
Not every card affords the same coverage. Most Visa cards will cover theft, damage to the rental car, towing and loss-of-use charges if you do not have a personal auto insurance policy. However, both Visa and Mastercard exclude injury, property damage and damage to other vehicles, according to website.
If your car is totaled, many companies will pay for your rental as a courtesy, but they are not required to do so. If you are filing a claim with your own insurance company, the cost of a rental car will only be covered if you paid a premium to include rentalreimbursement coverage in your policy.
It's technically not insurance but rather a waiver that says the rental car company won't come after you. Your policy: If you have collision and comprehensive coverage on your own policy, it generally will extend to a rental car. However, you will still be on the hook for your deductible.
One could say that if you loan your vehicle, you loan your insurance. If someoneother than the insured is driving a vehicle covered by comprehensive coverage and is not listed as a covered driver – even if the other person has permission – the other person might not be covered in an accident.


Money Play. How should Red play 31?
pips Red=136 White=210
(CorrectAnswer= 0/0, ErrorScore= 0)
23/20, 21/20 is too passive. It allows White to make Red’s bar-point most of the time, from which he could go forward or backward.
Red needs White to commit to a back game and therefore 8/7* will be part of the answer. After that there is very little difference between 23/20 and 12/9 for the 3. The key is to hit with 8/7* to attempt to force White into a back game. If things go well Red can build a prime and force White to crunch his home board but that is only one of very many possible outcomes from the starting position!
Not an easy problem by any means.

public abstract class Platform
extends java.lang.Object
Platform only provides framework-level interfaces, the specific
implementation of the interface implemented by subclasses for
different platforms. Before calling any operation ShareSDK, be
sure to initialize ShareSDK by calling the method
ShareSDK.initSDK(Context)
.
Generally, the best way to access the list of platforms
registered in ShareSDK is calling the method
ShareSDK.getPlatformList(Context)
, the use these platforms
to finish your operations. However, if you don't need to display
all platforms, you can also directly approach the right platform
by calling ShareSDK.getPlatform(Context, String)
.In fact,
ShareSDK.getPlatform(Context, String)
will determine
whether the platform is already cached in memory or not.If the
list is not cached, this method will still call
ShareSDK.getPlatformList(Context)
to organize a list of
platforms, then returns the requesting platform.
Most of the operations in ShareSDK (UI thread) are carried the
child thread, so these methods(such as share(ShareParams)
)
can be called directly in the UI thread. All these methods do not
have a return value, if you need to return value, you have to call
setPlatformActionListener(PlatformActionListener)
before
the operation. Then the result of the operation will be obtained
to PlatformActionListener.
ShareSDK offers three ways to set dev-info: registering informations
in assets/ShareSDK.xml, calling
ShareSDK#setPlatformDevInfo(String, HashMap
method to setting informations, or adding informations in ShareSDK
dev-console of your app.

send, sendto, sendmsg - send a message on a socket
#include <sys/types.h>
#include <sys/socket.h>
ssize_t send(int sockfd, const void *buf, size_t len, int flags);
ssize_t sendto(int sockfd, const void *buf, size_t len, int flags,
const struct sockaddr *dest_addr, socklen_t addrlen);
ssize_t sendmsg(int sockfd, const struct msghdr *msg, int flags);
The system calls send(), sendto(), and sendmsg() are used
to transmit a message to another socket.
The send() call may be used only when the socket is in a
connected state (so that the intended recipient is known). The only
difference between send() and write(2) is the presence of
flags. With a zero flags argument, send() is equivalent
to write(2). Also, the following call
send(sockfd, buf, len, flags);
is equivalent to
sendto(sockfd, buf, len, flags, NULL, 0);
The argument sockfd is the file descriptor of the sending
socket.
If sendto() is used on a connection-mode
(SOCK_STREAM, SOCK_SEQPACKET) socket, the arguments
dest_addr and addrlen are ignored (and the error
EISCONN may be returned when they are not NULL and 0), and the error
ENOTCONN is returned when the socket was not actually connected.
Otherwise, the address of the target is given by dest_addr with
addrlen specifying its size. For sendmsg(), the address of the
target is given by msg.msg_name, with msg.msg_namelen
specifying its size.
For send() and sendto(), the message is found in
buf and has length len. For sendmsg(), the message is
pointed to by the elements of the array msg.msg_iov. The
sendmsg() call also allows sending ancillary data (also known as
control information).
If the message is too long to pass atomically through the
underlying protocol, the error EMSGSIZE is returned, and the message
is not transmitted.
No indication of failure to deliver is implicit in a
send(). Locally detected errors are indicated by a return value of
-1.
When the message does not fit into the send buffer of the socket,
send() normally blocks, unless the socket has been placed in
nonblocking I/O mode. In nonblocking mode it would fail with the error
EAGAIN or EWOULDBLOCK in this case. The select(2) call
may be used to determine when it is possible to send more data.
The flags argument is the bitwise OR of zero or more of the following
flags.
- MSG_CONFIRM (since Linux 2.3.15)
- Tell the link layer that forward progress happened: you got a successful
reply from the other side. If the link layer doesn't get this it will
regularly reprobe the neighbor (e.g., via a unicast ARP). Valid only on
SOCK_DGRAM and SOCK_RAW sockets and currently implemented
only for IPv4 and IPv6. See arp(7) for details.
- MSG_DONTROUTE
- Don't use a gateway to send out the packet, send to hosts only on directly
connected networks. This is usually used only by diagnostic or routing
programs. This is defined only for protocol families that route; packet
sockets don't.
- MSG_DONTWAIT (since Linux 2.2)
- Enables nonblocking operation; if the operation would block, EAGAIN
or EWOULDBLOCK is returned. This provides similar behavior to
setting the O_NONBLOCK flag (via the fcntl(2) F_SETFL
operation), but differs in that MSG_DONTWAIT is a per-call option,
whereas O_NONBLOCK is a setting on the open file description (see
open(2)), which will affect all threads in the calling process and
as well as other processes that hold file descriptors referring to the
same open file description.
- MSG_EOR (since Linux 2.2)
- Terminates a record (when this notion is supported, as for sockets of type
SOCK_SEQPACKET).
- MSG_MORE (since Linux 2.4.4)
- The caller has more data to send. This flag is used with TCP sockets to
obtain the same effect as the TCP_CORK socket option (see
tcp(7)), with the difference that this flag can be set on a
per-call basis.
- Since Linux 2.6, this flag is also supported for UDP sockets, and informs
the kernel to package all of the data sent in calls with this flag set
into a single datagram which is transmitted only when a call is performed
that does not specify this flag. (See also the UDP_CORK socket
option described in udp(7).)
- MSG_NOSIGNAL (since Linux 2.2)
- Don't generate a SIGPIPE signal if the peer on a stream-oriented
socket has closed the connection. The EPIPE error is still
returned. This provides similar behavior to using sigaction(2) to
ignore SIGPIPE, but, whereas MSG_NOSIGNAL is a per-call
feature, ignoring SIGPIPE sets a process attribute that affects all
threads in the process.
- MSG_OOB
- Sends out-of-band data on sockets that support this notion (e.g.,
of type SOCK_STREAM); the underlying protocol must also support
out-of-band data.
The definition of the msghdr structure employed by sendmsg() is as
follows:
struct msghdr {
void *msg_name; /* Optional address */
socklen_t msg_namelen; /* Size of address */
struct iovec *msg_iov; /* Scatter/gather array */
size_t msg_iovlen; /* # elements in msg_iov */
void *msg_control; /* Ancillary data, see below */
size_t msg_controllen; /* Ancillary data buffer len */
int msg_flags; /* Flags (unused) */
};
The msg_name field is used on an unconnected socket to
specify the target address for a datagram. It points to a buffer containing
the address; the msg_namelen field should be set to the size of the
address. For a connected socket, these fields should be specified as NULL
and 0, respectively.
The msg_iov and msg_iovlen fields specify
scatter-gather locations, as for writev(2).
You may send control information using the msg_control and
msg_controllen members. The maximum control buffer length the kernel
can process is limited per socket by the value in
/proc/sys/net/core/optmem_max; see socket(7).
The msg_flags field is ignored.
On success, these calls return the number of bytes sent. On error, -1 is
returned, and errno is set appropriately.
These are some standard errors generated by the socket layer. Additional errors
may be generated and returned from the underlying protocol modules; see their
respective manual pages.
- EACCES
- (For UNIX domain sockets, which are identified by pathname) Write
permission is denied on the destination socket file, or search permission
is denied for one of the directories the path prefix. (See
path_resolution(7).)
- (For UDP sockets) An attempt was made to send to a network/broadcast
address as though it was a unicast address.
- EAGAIN or EWOULDBLOCK
- The socket is marked nonblocking and the requested operation would block.
POSIX.1-2001 allows either error to be returned for this case, and does
not require these constants to have the same value, so a portable
application should check for both possibilities.
- EAGAIN
- (Internet domain datagram sockets) The socket referred to by sockfd
had not previously been bound to an address and, upon attempting to bind
it to an ephemeral port, it was determined that all port numbers in the
ephemeral port range are currently in use. See the discussion of
/proc/sys/net/ipv4/ip_local_port_range in ip(7).
- EALREADY
- Another Fast Open is in progress.
- EBADF
- sockfd is not a valid open file descriptor.
- ECONNRESET
- Connection reset by peer.
- EDESTADDRREQ
- The socket is not connection-mode, and no peer address is set.
- EFAULT
- An invalid user space address was specified for an argument.
- EINTR
- A signal occurred before any data was transmitted; see
signal(7).
- EINVAL
- Invalid argument passed.
- EISCONN
- The connection-mode socket was connected already but a recipient was
specified. (Now either this error is returned, or the recipient
specification is ignored.)
- EMSGSIZE
- The socket type requires that message be sent atomically, and the size of
the message to be sent made this impossible.
- ENOBUFS
- The output queue for a network interface was full. This generally
indicates that the interface has stopped sending, but may be caused by
transient congestion. (Normally, this does not occur in Linux. Packets are
just silently dropped when a device queue overflows.)
- ENOMEM
- No memory available.
- ENOTCONN
- The socket is not connected, and no target has been given.
- ENOTSOCK
- The file descriptor sockfd does not refer to a socket.
- EOPNOTSUPP
- Some bit in the flags argument is inappropriate for the socket
type.
- EPIPE
- The local end has been shut down on a connection oriented socket. In this
case, the process will also receive a SIGPIPE unless
MSG_NOSIGNAL is set.
4.4BSD, SVr4, POSIX.1-2001. These interfaces first appeared in 4.2BSD.
POSIX.1-2001 describes only the MSG_OOB and MSG_EOR
flags. POSIX.1-2008 adds a specification of MSG_NOSIGNAL. The
MSG_CONFIRM flag is a Linux extension.
According to POSIX.1-2001, the msg_controllen field of the msghdr
structure should be typed as socklen_t, but glibc currently types it as
size_t.
See sendmmsg(2) for information about a Linux-specific
system call that can be used to transmit multiple datagrams in a single
call.
Linux may return EPIPE instead of ENOTCONN.
An example of the use of sendto() is shown in getaddrinfo(3).

Like in a Matrix :)...
If you want to decode it - you'll find the message interesting... A bit depressing, but I like to think about such kind of things.
 Here it is.
And here is what Ayende says about it :)

As a member of this class that had our time in college stripped from us due to circumstances out of our control, I’m happy to be back, but I’m sad this is the end. I think I speak for many of my peers when I can’t help but feel slighted, but life goes on, and it’s time for us to enjoy the precious time we have left while keeping our fingers crossed in hopes we don’t lose this year too.
If you find yourself on the opposite end of this spectrum as a member of OU’s two freshmen classes (or three depending on who you ask), you are experiencing your week of firsts, and for a long time everything will continue to feel brand new. Don’t take any of it for granted. Before you realize it, you will be on the other side of 21 as a washed up senior trying to make every day count, and, yes, in some ways you will miss the days when everything felt new and exciting.
It’s far too easy to spend the early weeks in Athens feeling anxious, wishing you had an established friend group and wishing you didn’t have to use a less than legal ID to get into bars. But those weeks quickly turn into months and years. Almost out of nowhere, you find yourself nervously looking at your student loan balance and applying for jobs wishing it went by a little slower. When the light is at the end of the tunnel, there are a lot of things you won’t miss about living in the dorms and being denied from half the bars on Court Street, but there’s also a lot you will miss.
Having a house uptown where you are free to do whatever you want, navigating campus with precision and confidence and knowing you can legally drink a beer are all amazing feelings, but they can’t quite compare to the frantic thrill of taking on Athens for the first time.
It’s almost inevitable to not appreciate the moment. Without using a cliche about the “good ole days,” it’s worth knowing that every phase of your time in Athens will come with a powerful and somber nostalgia once it’s passed. So, make the most of every day. In 2024, you’ll be glad you didn’t try to rush the early moments.

cc
resolved the following:
x1 : α, b1 : bool, x2 : α, b2 : bool, H2 : (x1, b1) ≠ (x2, b2), L : list (α × bool), H3 : L = (x1, b1) :: L₃, H4 : L = (x2, b2) :: L₄ ⊢ red L₃ ((x1, bnot b1) :: L)
which makes me wonder how cc
works
The docs say that it attempts to synthesize an empty inductive type
but it doesn't say how it achieves it
the printed theorem says:
false.elim (false_of_true_eq_false (eq.trans (eq.symm (eq_true_intro (and.elim_left (list.no_confusion (eq.trans (eq.symm H3) H4) (λ (hd_eq : (x1, b1) = (x2, b2)) (tl_eq : L₃ = L₄), ⟨hd_eq, tl_eq⟩))))) (eq_false_intro H2))))
I think it does so by building an equality matching graph. It's a graph where the vertices are terms and they are linked by edges if they are known to be equal. Once you've added all the equalities in your context, you take the transitive closure of the graph and, for each connected component (i.e. equivalence class) you can elect a term that will represent the whole class and replace every occurrence of every member of that class by that one representative.
It's a very algorithmic proof technique
very interesting
but the transitive closure isn't necessarily decidable?
It is because you're only considering the finite set of terms that are visible in your context (and some variation on each)
hmm
@Simon Hudon Congruence closure does one more thing: it closes these equivalences under congruence. For example if you know a=b
and have two subterms f a
and f b
, then it will deduce f a = f b
.
is there any paper regarding this?
Thanks for adding this detail! I could only think of it in algorithmic terms and that didn't seem enlightening. But your explanation is nice
I don't know a canonical citation off the top of my head, it's pretty standard stuff. Give me a sec.
thanks
Nelson, Oppen, Fast decision procedures based on congruence closure, Journal of the ACM (1980) http://www.cs.colorado.edu/~bec/courses/csci5535-s09/reading/nelson-oppen-congruence.pdf
The congruence lemmas for dependent type theory as used in Lean are described in this paper (de Moura, Selsam IJCAR 2016): https://leanprover.github.io/papers/congr.pdf
I'm always hesitant to try to read Lean papers because I always fear they will be outdated (say Lean 2 era or worse) and only confuse me
The cc
implementation in Lean does a few more tricks: for example it derives a=b
from nat.succ a = nat.succ b
, and nat.succ a != nat.zero
for any a
.
Do you have something like a list of still relevant Lean papers?
theorem test (α : Type*) (f : α → α) (x : α) (H1 : f (f (f x)) = x) (H2 : f (f (f (f (f x)))) = x) : f x = x := by cc #print test /-of_eq_true (eq_true_intro (eq.trans (eq_of_heq ((λ (a a' : α) (e_0 : a = a'), eq.rec (heq.refl (f a)) e_0) x (f (f x)) (eq.trans (eq.symm H2) (eq_of_heq ((λ (a a' : α) (e_0 : a = a'), eq.rec (heq.refl (f a)) e_0) (f (f (f (f x)))) (f x) (eq_of_heq ((λ (a a' : α) (e_0 : a = a'), eq.rec (heq.refl (f a)) e_0) (f (f (f x))) x H1))))))) H1))-/
Wow
(taken from P.1 of the first linked paper)
@Patrick Massot Let me look through the publication list at https://leanprover.github.io/publications/. The system description is pretty high-level and only obsolete in details. The metaprogramming paper is new and describes Lean 3.2. The machine learning paper doesn't seem to talk much about Lean. The congruence closure paper seems to be still relevant. The elaboration paper is completely obsolete as it describes Lean 2.
The congruence lemmas for dependent type theory as used in Lean are described in this paper (de Moura, Selsam IJCAR 2016): https://leanprover.github.io/papers/congr.pdf
of course it is de moura :P
Thanks
So actually the obsolete one is clearly flagged Lean 2 on https://leanprover.github.io/publications/
It reminds me a question: what is the status of super
today?
And these crush
things mentioned in the metaprogramming paper and some slides?
super
never progressed beyond a proof of concept. From my point of view, the main thing holding it back is performance. Some APIs that would be very nice to do e.g. resolution with unification (such as temporary metavariables) are simply not available from the metaprogramming side. And I have enough other things to do. Maybe I will revisit super
when Lean 4 arrives.
crush
is available as a package: https://github.com/leanprover/mini_crush
rsimp
is in the core library
What does rsimp
do?
Re: super
. This was the first thing I did with Lean, and at the time I did not know about typeclasses, simp lemmas, the equation compiler, etc. It did not help that the Lean 3 library at the time did not even have more than a few theorems about natural numbers.
@Simon Hudon: rsimp
is Leo's idea on how to do simplification with congruence closure. As you've observed, cc
stores the equivalence classes of subterms. Roughly, rsimp
then applies simp lemmas on the subterms, and traverses the equivalence classes to pick the smallest subterm as a result.
The main advantage compared to simp
is that it doesn't loop (so easily). For example, simp*
would loop on a=b, b=a :- f a = f b
but rsimp
would not.
why would it not loop on a=b b=a?
That is so cool :) Is there a downside to using rsimp
instead of simp
?
Just looked back at the paper and apparently I remembered it incorrectly, rsimp
uses E-matching to instantiate lemmas instead of simp
. So in the example above, rsimp
is essentially cc
.
Thanks. Indeed it sounds like super
needs to wait for Lean 4.
Maybe more interestingly: if you call rsimp on a=b, a=f a :- p (f (f a))
then rsimp would simplify the goal to p a
(or p b
, randomly).
I found that cc
automatically does intros
I was wondering if it rewrote the conditions like simp
does
I think that's less efficient so I don't prefer it rewriting the conditions
so I like cc
more :P
I was wondering if it rewrote the conditions like
simp
does
What do mean by "rewriting conditions"?
so the goal is A -> B
simp would rewrite A
to C
without intro right
I'm not sure if there is a meaningful difference in efficiency here. The reason why simp
does not do intros
is because simp
may not close the goal and you don't want simp
to intro stuff randomly. On the other hand, cc
is an end-game tactic and can do whatever it wants.
I see

 The entire time I was going through the time and habits links this wonderful lady kept popping into my head.
The Pomodoro Technique a really cool idea but putting it into practice is so much harder then it seemed. This is basically how it went like this:
Somewhere in the recesses of Pearl's brain...
"Right, have all my Pomodoro's outlined for today... Start toggl."
Half way through the exercise:
*BUZZ* Toggl says time is up! "Ahh, OK need another Pomodoro for that task, no problem."
Some large amount of time later:
*BUZZ* Toggl says 'Don't forget to turn on your toggl!  OK, turn you on now but have totally lost track of where my timings at."
2 minutes later:
"Oh geez I gotta pee."

Everything was interesting - especially the 'Get in the zone' stuff. Most of the techniques were simple but simple is the hardest to get right. Simple is hardly ever easy. I think a more apt title for me would have been "Masocistic Time Management!"
I found everything hard but as we learned habits need to be started small to be able to make big change. I'll keep doing the time management stuff especially and hopefully it will become easier as I become more practiced.
Oh for F*#$% sake! My toggl's not on...
Mastery of the Pomodoro Technique.
