Video: Mason Greenwood pounces to level for Man United vs Sheffield United
by Tom McNeilWell this has come from nowhere.
Brandon Williams got his side back into the game with a lovely finish, before Mason Greenwood leveled things up moments afterwards. It’s a great ball from Rashford and Greenwood shows some great instincts to guide the ball home:
It took an even bigger turn minutes later when Rashford actually put Ole Gunnar Solskjaer’s men in front. Can they hold on for an important victory?

RIT YDSA ENDORSES BERNIE SANDERS FOR US PRESIDENT - JANUARY 3RD, 2020
Rochester Institute of Technology's chapter of the Young Democratic Socialists of America endorses candidate Bernie Sanders for election in this year's US presidential race. Sanders' long-running commitment to compassionate justice serves as a preeminent example of socialist action. RIT YDSA stands with Senator Sanders as we prepare for the upcoming Iowa Caucus.
Sanders' consistent support of wealth redistribution is of particular relevance to the lives of RIT students. The senator has repeatedly stood against the coercive forces of surveillance capitalism that plague students from all backgrounds. Graduating students are left vulnerable when they enter a labor market that is anti-union and queer-opposed. Sanders and his socialist contemporaries offer up a truly democratic alternative to capitalism's systemic power inequalities. With a history of direct action against discriminatory wealth policing, Sanders sets himself apart from presidential candidates that do little but propose ineffectual tweaks to the status quo. RIT YDSA members have highlighted Medicare for All, pacifist international relations, and internet-as-utility legislation as actionable Sanders-led proposals set to minimize capitalistic injustice both within the United States and abroad.

9.3 Tools and TechniquesWith an understanding of the various backup-related issues you need to consider, let's move on to examining the tools available. If you have a complex configuration or unusual needs, there's a chance that none of these alone will do the job for you. Instead, you'll need to build a custom solution—possibly using one or more of the tools described here. This section isn't intended to be a comprehensive reference for each tool. Instead, it focuses on presenting the relevant features of each one so that you better understand your choices. Once you've selected a tool, be sure to consult the documentation for it. There's a good chance that the tool has options that didn't exist when this book was written. We will post news about available tools at our web site: http://highperformancemysql.com (see the Preface for more information). 9.3.1 mysqldumpFor a long time, mysqldump was the only backup tool available for MySQL. It is a command-line utility for dumping tables of any type into SQL flat files. It even handles foreign-key constraints properly. mysqldump comes with MySQL, so you're guaranteed to have it installed already. Using mysqldump to perform dumps is ideally suited to backing up small databases. The resulting files are large compared to the data being dumped, and it's not a very efficient process. To back up all the databases on a server, execute the following command: $ mysqldump -u root -pPassword -x --all-databases > dump.sql The -x flag tells mysqldump to lock all tables during the backup to ensure consistency. There are a few drawbacks to that method. Most importantly, the entire dump will go to a single file, which can result in a very large file if you have a lot of data to back up. mysqldump doesn't have an option to split the output into separate files based on database or table name. If you need to back up a subset of all the databases, you can provide a list of database names on the command line: $ mysqldump -u root -pPassword -x --databases db1 db2 db3 > dump.sql This creates a dump file with the information necessary to recreate the db1, db2, and db3 databases. If you need to back up only a few tables from a single database, you can provide the database and table names: $ mysqldump -u root -pPassword -x db1 table1 table2 table3 > dump.sql mysqldump works well over the network, too. By adding a -h argument, you tell it to connect to a remote MySQL host instead: $ mysqldump -h db.example.com -u root -pPassword -x --all-databases > dump.sql <IP_ADDRESS> RestoringNo matter which options you use, restoring a dump is always straightforward. Simply feed the dump file back through the mysql command-line tool: $ mysql -u root -pPassword < dump.sql If you find yourself restoring dump files frequently (perhaps on a test server), consider using mysqldump's --extended-insert option. It tells mysqldump to bundle many insert statements together using MySQL's bulk insert syntax: INSERT INTO mytable (col1, col2, col3) VALUES (val1, val2, val3) (val1, val2, val3) ... This makes the restore run far faster than the default method, which uses one insert statement per row. It also results in much smaller dump files. Normally, mysqldump requests all the rows for the table it is dumping, buffers them in memory, and writes the data to disk. It does this to minimize the amount of time tables are locked on the server. However, when dumping large tables, you need to use the --quick option; it prevents the buffering, instead telling mysqldump to fetch rows from the server one at a time. While it's a bit slower[5] than the default method, it's the only option when your tables are too big to fit in memory on the host that's running the dump.
In fact, you might consider using the --opt option. It enables several useful options at once, including --quick and --extended-insert. Windows users should use the --result-file option to specify an output file: $ mysqldump -u root -pPassword --all-databases --result-file=dump.sql Otherwise, Windows converts all newline characters (\n) to a carriage return plus newline (\r\n). The silent conversion will cause endless frustration when you need to restore a table in a hurry. 9.3.2 mysqlhotcopyOriginally created by Tim Bunce (the architect of Perl's DBI), mysqlhotcopy is a Perl script included in the standard MySQL distributions. Its purpose is to automate the process of backing up a database consisting of ISAM and MyISAM tables while the server is running. It's the most popular tool available for performing online raw backups and is best suited to backing up single databases on a live server. It operates by getting a read lock on all the tables to be copied, copying them, and then releasing the lock. This means it doesn't scale very well as traffic or size increase. To back up a live database, such as the test database, run: $ mysqlhotcopy -u root -p Password test /tmp You'll end up with a test subdirectory in /tmp that contains all the tables from the backed up database. $ ls -l /tmp/test total 108 -rw-rw---- 1 mysql users 8550 May 3 12:02 archive.frm -rw-rw---- 1 mysql users 25 May 3 12:02 archive.MYD -rw-rw---- 1 mysql users 2048 May 23 12:58 archive.MYI -rw-rw---- 1 mysql users 8924 Mar 4 21:52 contacts.frm -rw-rw---- 1 mysql users 7500 Mar 5 21:11 contacts.MYD -rw-rw---- 1 mysql users 5120 May 23 12:58 contacts.MYI -rw-rw---- 1 mysql users 8550 May 3 12:02 dirty.frm -rw-rw---- 1 mysql users 25 May 3 12:02 dirty.MYD -rw-rw---- 1 mysql users 2048 May 23 12:58 dirty.MYI -rwxr-xr-x 1 mysql users 8558 Feb 26 2001 maybe_bug.frm* -rwxr-xr-x 1 mysql users 45 Feb 26 2001 maybe_bug.MYD* -rwxr-xr-x 1 mysql users 2048 May 23 12:58 maybe_bug.MYI* -rwxr-xr-x 1 mysql users 8715 Jan 15 2001 test_more_info.frm* -rwxr-xr-x 1 mysql users 784 Jan 16 2001 test_more_info.MYD* -rwxr-xr-x 1 mysql users 2048 May 23 12:58 test_more_info.MYI* As you can see, mysqlhotcopy copies the data (.MYD), index (.MYI), and table definition (.frm) files for each table in the test database. To conserve space, you may choose to back up only the .frm and .MYD files in their entirety. Given the --noindices option, mysqlhotcopy copies only the first 2,048 bytes of each .MYI file. That's all MySQL needs to reconstruct the indexes at a later date. $ mysqlhotcopy -u root -p Password --noindices test /tmp Because it is written in Perl, mysqlhotcopy has support for regular expressions too. To back up every database that contains the string test in its name, run: $ mysqlhotcopy -u root -p Password --regexp=test /tmp In practice, few users use that capability, but it is there. <IP_ADDRESS> RestoringTo restore one or more tables, simply copy the files into the proper subdirectory of MySQL's data directory. For example, if you need to restore the test_more_info table into the test database, run: $ cp /tmp/test/test_more_info.* datadir/test
If you used the --noindices option to truncate the .MYI files, you need to repair the tables before you can use them. You can use either the myisamchk -r command: $ cd datadir/test
$ myisamchk -r test_more_info
or the REPAIR TABLE test_more_info command from within MySQL: mysql> REPAIR TABLE test_more_info That's all there is to it. You can then freely use the restored table. 9.3.3 mysqlsnapshotJeremy originally wrote mysqlsnapshot to simplify the process of configuring replication slaves at Yahoo! using MySQL 3.23.xx. As the amount of data grew, he realized one day that a better online backup system was needed. After working with the code for mysqlsnapshot, Jeremy realized that if he added one more feature it would do the job quite well. In addition, it would be a much smaller and easier to maintain than mysqlhotcopy. He hasn't yet submitted mysqlsnapshot for inclusion in the MySQL distribution. It may be there by the time you read this, but if not, you can find it at http://jeremy.zawodny.com/mysql/mysqlsnapshot/. mysqlsnapshot is best used to back up an entire database server without taking it offline. It has no options for specifying particular databases or tables to include or exclude in the process. It copies everything. To back up all databases on a server, run: $ mysqlsnapshot -u root -p Password -s /tmp/snap --split -n checking for binary logging... ok backing up db database... done backing up db jzawodn... done backing up db mysql... done backing up db nuke... done backing up db phplib... done backing up db prout... done backing up db test... done snapshot completed in /tmp/snap/ This results in one tar file for each database, written to the /tmp/snap directory. If you remove the --split option, mysqlsnapshot puts all the data in a single tar file. If you supply the -z argument, it compresses the backup using gzip. <IP_ADDRESS> RestoringRestoring a backup created with mysqlsnapshot is just a matter of untarring the files in MySQL's data directory. To restore the prout database, you execute: $ cd datadir/test $ tar -xvf /tmp/prout.tar This illustrates one reason you ought to consider keeping each database in a separate tar file. By doing so, your backups will be more manageable (you can selectively delete them on a per-database basis), and you can be selective about what you restore. 9.3.4 InnoDB Hot BackupIf you're keeping a large amount of data in InnoDB and would like online backups, the InnoDB Hot Backup tool is the best choice. Unlike MySQL, it's not free. Rather, it's a relatively inexpensive commercial tool developed by the makers of InnoDB. See http://www.innodb.com/hotbackup.html for details. To use the Hot Backup Tool (ibbackup), you create a configuration file that tells ibbackup where to archive the data. Then run it like this: $ ibbackup /etc/my.cnf /etc/ibbackup.cnf The backup tool needs to read the MySQL configuration file as well as its own configuration. Recent versions of ibbackup have added the ability to compress the backup (--compress). It's important to note that ibbackup doesn't back up the .frm files for your tables. So even if you use InnoDB tables exclusively in MySQL, you still need to back up the .frm files separately from using ibbackup. This is slated to change in the future, so check the InnoDB manual for the most recent news. Restoring a backup is a straightforward process. With MySQL offline, simply run: $ ibbackup --restore /etc/ibbackup.cnf 9.3.5 Offline BackupsAs discussed earlier, there are numerous benefits to shutting down MySQL before performing a backup. To recap:
If you are using a home-grown backup script of some sort, simply add a call to the mysqladmin command like this: # Now, shut down MySQL before the backup begins. mysqladmin -u root -pPassword shutdown # And start the backup ... # Then bring MySQL back up /usr/local/mysql/bin/mysqld_safe & If you use a prepackaged backup system, you need to ensure that MySQL is down before it starts. If the backup software is run locally on the MySQL server, that's easy. Rather than running the software directly, create a small shell script or batch file that handles the stopping and starting of MySQL around the backup process—much like the previous example. In larger environments, it is common to run client/server backup software. The backup server contacts a daemon running on a remote server when it is time for the backup process to begin. That daemon (running on your MySQL server) then feeds data to the backup server over the network. It is also common in such environments to let the backup software control the exact starting time of the backup. In a case like that, you may need to find an alternative approach for backing up MySQL, or you'll need to do some digging in the backup software's manual. There's a good chance that you can find a way to make the backup software start and stop MySQL when it needs to. If not, you may be able to use one of the other backup strategies. If you have sufficient disk space, you can perform the backup directly on the MySQL server and let your normal backup process back up those files. <IP_ADDRESS> RestoringOnce again, MySQL makes it easy to restore data.[6] Unless you're restoring the entire MySQL installation, you need to recover the files that make up the tables and databases you need to restore. Once you have them, copy them back into MySQL's data directory and start MySQL.
9.3.6 Filesystem SnapshotsTaking a snapshot of MySQL's data is the fastest and least intrusive method of backing up an online server. While the implementation details vary, a snapshot is an online copy of your data—usually stored on the same filesystem or volume. In fact, most systems use a copy-on-write scheme to minimize the free space required to take a snapshot. MySQL itself provides no support for taking snapshots, but various free and commercial filesystems and storage solutions do. In the Linux world, LVM (the Linux volume manager) has snapshot capabilities. Veritas sells a filesystem product for most versions of Unix (and Linux) that can take snapshots. FreeBSD 5.x may offer snapshot capabilities too. In the hardware space, Network Appliance's popular "filers" can be used to take filesystem snapshots. EMC has two ways of doing this: snapshots, which are just like the snapshots described above, and BCVs (business continuance volumes). They are, in effect, additional mirrors of a volume that can be broken off and mounted on other systems. They require double the amount of storage and are therefore expensive. Snapshots are best used with a more traditional backup solution. By itself, a snapshot doesn't do much to guard against hardware failures. Sure, you can use a snapshot to quickly restore an accidentally dropped table, but all the snapshots in the world won't help if the disk controller catches fire. Be sure that you have sufficient space reserved on your volume for the number of snapshots you plan to keep online. Most snapshot-capable filesystems require that you reserve a minimum amount of disk space for snapshot data. If your server processes a lot of write queries, you can easily exceed the reserved space. Check your filesystem documentation for complete details. Just as with the other approach to online backups, you must be careful to flush and obtain a read lock on all ISAM and MyISAM tables before initiating a snapshot. The easiest way to do this is to use MySQL's FLUSH TABLES WITH READ LOCK command. It will hold the lock until you disconnect from MySQL or issue an UNLOCK TABLES command. We'll discuss this in the next section. |

As a dedicated telephone helpline,SAHAI was started in October 2002 in response to the growing incidences of suicide in the city of Bangaore. The service was initiated with the assistance of NIMHANS,Rotary East and Medico Pastoral Association. Today it is a service provided by Medico Pastoral Association which is a psycho social rehabilitation centre for people with mental illness.
Medico Pastoral Association has been running mental health services since 1972. It has been involved in running the suicide prevention helpline - SAHAI, since its launch on 02 October 2002. Medico Pastoral Association conducts regular public awareness campaigns on suicide prevention through workshops, seminars, plays and poster campaigns. SAHAI operates from the premises of the Medico Pastoral Association.
Its former director, Dr.R.M.Varma inaugurated the first training programme in suicide prevention for volunteers in October 2002. A study on 'The Epidemiology of Suicide in Bangalore' by Dr. G. Gururaj and Dr.Mohan Isaac of NIMHANS was instrumental in the setting up the SAHAI Helpline.
SAHAI began as a service project of Rotary Bangalore East. "We've been effective in our work at the SAHAI Helpline because of the close co-ordination between the 3 partners: Rotary Bangalore East, NIMHANS and the Medico Pastoral Association" says Rotary Bangalore East's former President, Mr.K.K.Rajagopal.
Rotary Bangalore East has won many awards in recognition of its leadership role in addressing distress. Rotary Bangalore East has also been actively involved with other public awareness building activities.
Whether you're facing problems with your family, in school, at work or with your friends. Our Counselors will give you their undivided attention and will guide you through telephone counseling. SAHAI volunteers will help and equip you with the skills needed to cope with distressing situations of life like loss, failure, broken relationships or the ever-increasing demands of today's fast-paced life.
Talking about it with families and friends or sharing your feelings may be difficult. Maybe you don’t wish to worry those who are close to you or maybe you feel that you may be misunderstood or perhaps you don’t know how to explain the way you are feeling!
That’s when you might wish to talk to the trained volunteers at SAHAI. They are available to listen to you with empathy. They can offer alternative options or suggest people who can help with specific problems.
The service is completely confidential and free.
So next time you are feeling down, it might help to call SAHAI.
Call between 10.00a.m to 8p.m(Monday through Saturday).

do
echo "$var"
done
Correct code depends on what you want to do.
To iterate over files in a directory, instead of for var in /my/dir
use:
for var in /my/dir/* ; do echo "$var"; done
To iterate over lines in a file or command output, use a while read loop instead:
mycommand | while IFS= read -r line; do echo "$line"; done
To iterate over words written to a command or function's stdout, instead of for var in myfunction
, use
for var in $(myfunction); do echo "$var"; done
To iterate over words in a variable, instead of for var in myvariable
, use
for var in $myvariable; do echo "$var"; done
ShellCheck has detected that your for loop iterates over a single, constant value. This is most likely a bug in your code, caused by you not expanding the value in the way you want.
You should make sure that whatever you loop over will expand into multiple words.
None.

DAP to Netcdf Translation Rules
Two translations are currently available.
netCDF-3 Translation Rules
The current set of translation rules to convert an OPeNDAP
DAP protocol version 2 DDS to netCDF-3 is designed to mimic
as closely as possible those currently used by the libnc-dap
system. Please note that the translation is still subject
to change to respond to unforeseen problems and user
suggestions.
For illustrative purposes, the following example will be used.
Dataset {
Int32 f1;
Structure {
Int32 f11;
Structure {
Int32 f1[3];
Int32 f2;
} FS2[2];
} S1;
Structure {
Grid {
Array:
Float32 temp[lat=2][lon=2];
Maps:
Int32 lat[lat=2];
Int32 lon[lon=2];
} G1;
} S2;
Grid {
Array:
Float32 G2[lat=2][lon=2];
Maps:
Int32 lat[2];
Int32 lon[2];
} G2;
Int32 lat[lat=2];
Int32 lon[lon=2];
} D1;
Variable Definition
The set of variables is defined by the fields with
primitive base types as they occur in
Sequences, Grids, and Structures.
The field names are modified to be fully qualified initially.
For the above, the set of variables, the variables are as follows.
- f1
- S1.f11
- S1.FS2.f1
- S1.FS2.f2
- S2.G1.temp
- S2.G1.lat
- S2.G1.lon
- S2.G2.G2
- S2.G2.lat
- S2.G2.lon
- lat
- lon
Variable Dimension Translation
A variable's rank is determined from three sources.
-
The variable has the dimensions associated with the field
it represents (e.g. S1.FS2.f1[3] in the above example).
-
The variable inherits the dimensions associated with any containing
structure that has a rank greater than zero.
These dimensions precede those of case 1.
Thus, we have in our example, f1[2][3], where the first dimension
comes from the containing Structure FS2[2].
-
The variable's set of dimensions are altered
if any of its containers is a DAP DDS Sequence.
This is discussed more fully below.
Dimension translation
For dimensions, the rules are as follows.
- Fields in dimensioned structures inherit the dimension
of the structure; thus the above list would have the following
dimensioned variables.
- S1.FS2.f1 -> S1.FS2.f1[2][3]
- S1.FS2.f2 -> S1.FS2.f2[2]
- S2.G1.temp -> S2.G1.temp[lat=2][lon=2]
- S2.G1.lat -> S2.G1.lat[lat=2]
- S2.G1.lon -> S2.G1.lon[lon=2]
- S2.G2.G2 -> S2.G2.lon[lat=2][lon=2]
- S2.G2.lat -> S2.G2.lat[lat=2]
- S2.G2.lon -> S2.G2.lon[lon=2]
- lat -> lat[lat=2]
- lon -> lon[lon=2]
-
Collect all of the dimension specifications from the DDS, both
named and anonymous (unnamed)
For each unique anonymous dimension with value NN
create a netCDF dimension of the form "<array>_<i>=NN",
where is the fully qualified name of the variable and i is the
i'th (inherited) dimension of the array where the anonymous dimension occurs.
For our example, this would create the following dimensions.
- S1.FS2.f1_0 = 2 ;
- S1.FS2.f1_1 = 3 ;
- S1.FS2.f2_0 = 2 ;
- S2.G2.lat_0 = 2 ;
- S2.G2.lon_0 = 2 ;
-
If, however, the anonymous dimension is the single dimension
of a MAP vector in a Grid then the dimension is given the
same name as the map vector This leads to the following.
- S2.G2.lat_0 -> S2.G2.lat
- S2.G2.lon_0 -> S2.G2.lon
-
For each unique named dimension "<name>=NN",
create a netCDF dimension of the form "<name>=NN",
where name has the qualifications removed.
If this leads to duplicates (i.e. same name and same value),
then the duplicates are ignored.
This produces the following.
- S2.G2.lat -> lat
- S2.G2.lon -> lon
Note that this produces duplicates.
-
At this point the only dimensions left to process should be named
dimensions with the same name as some dimension from step number 3,
but with a different value. For those dimensions create a dimension
of the form "<name>M=NN" where M is a counter starting at 1.
The example has no instances of this.
-
Finally and if needed, define a single UNLIMITED dimension named "unlimited"
with value zero.
This leads to the following set of dimensions.
dimensions:
unlimited = UNLIMITED;
lat = 2 ;
lon = 2 ;
S1.FS2.f1_0 = 2 ;
S1.FS2.f1_1 = 3 ;
S1.FS2.f2_0 = 2 ;
Variable Name Translation
The steps for variable name translation are as follows.
- Take the set of variables captured above.
Thus for the above DDS, the following fields would be collected.
- f1
- S1.f11
- S1.FS2.f1
- S1.FS2.f2
- S2.G1.temp
- S2.G1.lat
- S2.G1.lon
- S2.G2.G2
- S2.G2.lat
- S2.G2.lon
- lat
- lon
- All grid array variables are renamed to be the same as the containing
grid and the grid prefix is removed.
In the above DDS, this results in the following changes.
- G1.temp -> G1
- G2.G2 -> G2
Note that, for example, the G1.lon keeps that name.
Also note that libnc-dap just drops the grid map variables,
so this is one place where the translation differs from
libnc-dap, but in a compatible way.
It is important to note that if this process could produce duplicate
variables (i.e. with the same name); in that case they are all assumed
to have the same content and the duplicates are ignored.
If it turns out that the duplicates have different content, then
the translation will not detect this. YOU HAVE BEEN WARNED.
The final netCDF-3 schema (minus attributes) is then as follows.
netcdf t {
dimensions:
unlimited = UNLIMITED
lat = 2 ;
lon = 2 ;
S1.FS2.f1_0 = 2 ;
S1.FS2.f1_1 = 3 ;
S1.FS2.f2_0 = 2 ;
variables:
int f1 ;
int lat(lat) ;
int lon(lon) ;
int S1.f11 ;
int S1.FS2.f1(S1.FS2.f1_0, S1.FS2.f1_1) ;
int S1.FS2.f2(S1_FS2_f2_0) ;
float S2.G1(lat, lon) ;
int S2.G1.lat(lat) ;
int S2.G1.lon(lon) ;
float G2(lat, lon) ;
int G2.lat(lat) ;
int G2.lon(lon) ;
}
In actuality, the unlimited dimension is dropped because
it is unused.
There are differences with the original libnc-dap here
because libnc-dap technically was incorrect. The original
would have said this, for example.
int S1.FS2.f1(lat, lat) ;
Note that this is incorrect because it dimensions
S1.FS2.f1(2,2) rather than S1.FS2.f1(2,3).
Translating DAP DDS Sequences
Any variable (as determined above) that is contained
directly or indirectly by a Sequence is subject to revision
of its rank using the following rules.
-
Let the variable be contained in Sequence Q1, where Q1 is the
innermost containing sequence. If Q1 is itself contained
(directly or indirectly) in a sequence,
or Q1 is contained (again directly or indirectly)
in a structure that has rank greater than 0,
then the variable will have an initial UNLIMITED
dimension. However, all dimensions coming from "above" and including (in
the containment sense) the innermost Sequence, Q1, will be
removed and replaced by the single UNLIMITED dimension. The
size associated with that UNLIMITED is zero, which means
that its contents are inaccessible through the netcdf-3 API.
Again, this differs from libnc-dap, which leaves out such variables.
Again, however, this difference is compatible.
-
If the variable is contained in a single Sequence (i.e. not nested)
and all containing structures have rank 0, then the variable will
have an initial dimension whose size is the record count for that
Sequence. The name of the new dimension will be the name of the
Sequence.
Consider this example.
Dataset {
Structure {
Sequence {
Int32 f1[3];
Int32 f2;
} SQ1;
} S1[2];
Sequence {
Structure {
Int32 x1[7];
} S2[5];
} Q2;
} D;
The corresponding netcdf-3 translation is pretty much as follows
(the value for dimension Q2 may differ).
dimensions:
unlimited = UNLIMITED ; // (0 currently)
S1.SQ1.f1_0 = 2 ;
S1.SQ1.f1_1 = 3 ;
S1.SQ1.f2_0 = 2 ;
Q2.S2.x1_0 = 5 ;
Q2.S2.x1_1 = 7 ;
Q2 = 5 ;
variables:
int S1.SQ1.f1(unlimited, S1.SQ1.f1_1) ;
int S1.SQ1.f2(unlimited) ;
int Q2.S2.x1(Q2, Q2.S2.x1_0, Q2.S2.x1_1) ;
Note that for example S1.SQ1.f1_0
is not actually used because it has been folded
into the unlimited dimension.
Note that there is a performance cost
because the translation code has to walk the data to determine
how many records are associated with the sequence.
Since libnc-dap did something similar, it can be assumed that
the cost is not prohibitive.
The DAP to netCDF-4 translation is enabled if the
"--enable-netcdf-4" option is specified at configure time.
This translation includes some elements of the libnc-dap
translation, but attempts to provide a simpler (but not,
unfortunately, simple) set of translation rules than is used
for the netCDF-3 translation.
Please note that the translation is still subject
to change to respond to unforeseen problems or to
suggested improvements.
This text will use this running example.
Dataset {
Int32 f1[fdim=10];
Structure {
Int32 f11;
Structure {
Int32 f1[3];
Int32 f2;
} FS2[2];
} S1;
Grid {
Array:
Float32 temp[lat=2][lon=2];
Maps:
Int32 lat[2];
Int32 lon[2];
} G1;
Sequence {
Float64 depth;
} Q1;
} D
Variable Definition
The rules for choosing variables is as follows.
- Start with the names of the top-level fields of the DDS.
The term top-level means that the object is a direct subnode
of the Dataset object. In our example, this produces the set
[f1, S1, G1, Q1].
-
Replace all Grid objects with the fully qualified list of array
and map fields of the grid.
Our variable set then becomes [f1, S1, G1.temp, G1.lat, G1.lon, Q1].
Note that the libnc-dap practice of re-naming the array variable to be
that of the Grid is not used.
-
Attempt to remove the prefix Grid name from the top-level Grid array and map
variables. If that eventually conflicts with some other name,
then leave the conflicting Grids alone.
Our variable set then becomes [f1, S1, temp, lat, lon, Q1].
-
If the Grid array name is the same as the Grid name, then
remove the prefix Grid name (not shown).
Dimension Definition
The rules for choosing and defining dimensions is as follows.
-
Collect the set of dimensions (named and anonymous) directly
associated with the variables as defined above.
This means that dimensions
within user-defined types are ignored. From our example,
the dimension set is [fdim=10,lat=2,lon=2,2,2]. Note that the
unqualified names are used.
-
If an anonymous dimension is associated with a Grid Map variable,
then given the dimension, the name of the map.
Our dimension set now becomes
[fdim=10,lat=2,lon=2,lat=2,lon=2].
-
All remaining anonymous dimensions are given the
name "<var>_NN", where "<var>" is the
unqualified name of the variable in which the anonymous
dimension appears and NN is the relative position of that
dimension in the dimensions associated with that array.
No instances of this rule occur in the running example.
-
Remove duplicate dimensions (those with same name and value).
Our dimension set now becomes
[fdim=10,lat=2,lon=2].
-
The final case occurs when there are dimensions with the same
name but with different values. For this case,
the size of the dimension is appended to the dimension name.
Type Definition
The rules for choosing user-defined types are as follows.
- For every Structure, Sequence, and non-top-level Grid,
netcdf-4 compound type is created whose fields are the fields
of the Structure, Sequence, or Grid. The name of the type is the
same as the Structure or Grid name suffixed with "_t".
However, the compound types derived from Sequences are instead
suffixed with "_record_t".
The types of the fields are the types of the corresponding field
of the Structure, Sequence, or Grid. Note that this type
might be itself a user-defined type.
From the example, we get the following compound types.
compound FS2_t {
int f1[3];
int f2;
};
compound S1_t {
int f11;
FS2_t FS2[2];
};
compound Q1_record_t {
double depth;
};
-
For all sequences of name X,
also create this type.
X_record_t (*) X_t
In our example, this produces the following type.
Q1_record_t (*) Q1_t
-
If a Sequence, Q has a single field F,
whose type is a primitive type, T,
(e.g., int, float, string), then
do not apply the previous rule, but instead replace the whole
sequence with the the following field.
T (*) Q.f
-
Attempt to maximally shorten the type names as long as there is no conflict.
Choosing a Translation
The decision about whether to translate to netCDF-3
(libnc-dap) or netCDF-4 is determined by applying the
following rules in order.
-
If the NC_CLASSIC_MODEL flag is set on nc_open(), then netcdf-3
(i.e. libnc-dap) translation is used.
-
If the NC_NETCDF4 flag is set on nc_open(), then netCDF-4
translation is used.
-
If the URL is prefixed with the string
"[mode=netcdf3]" or "[mode=libnc-dap]",
then the libnc-dap translation is used.
-
If the URL is prefixed with the string "[mode=netcdf4]",
then the netCDF-4 translation described below is used.
-
If none of the above is specified, then the default
is "[mode=libnc-dap]".
Defined Client Parameters
Currently, a limited set of client parameters is recognized.
Parameters not listed here are ignored, but no error is signalled.
| Parameter Name | Legal Values | Semantics
|
|---|
| [mode=...] | libnc‑dap|netcdf3|netcdf4
| Specify the translation to be applied to the DAP data source on the
client side.
|
| [show=...] | das|dds|url
| This causes information to appear as specific global attributes. The
tags may be combined using comma with no spaces
(e.g. "show=dds,url"). The currently recognized tags are "dds" to
display the underlying DDS, "das" similarly, and "url" to display
the url used to retrieve the data.

Grand Master Meldina:
Nothing important. He just asked when the freight will arrive -- at the pier in Giran tomorrow, as it happens. Perhaps you will be able to find him there. Ask the wharf manager, Felton, about the freight itself if you are curious.

2013 CS140 Final Exam - Answers and Grading
James S. Plank
Question 1 - Basic Programming - 10 Points
Here you simply read the lines and put them into a data structure
which allows you to retain the last n lines efficiently. It's
not easy with a vector, because you cannot insert or delete
efficiently from the front of a vector -- you do better to use a
deque or list from the STL, or a Queue or
Dlist from the lecture notes/labs. In the code below, I
create the deque in reverse order, and then create the return vector
from it
(this in q1.cpp):
#include <vector>
#include <deque>
#include <string>
#include <iostream>
using namespace std;
vector <string> get_n_lines(int n)
{
vector <string> rv;
deque <string> q;
string s;
int i;
while (getline(cin, s)) {
q.push_front(s);
if (q.size() > n) q.pop_back();
}
for (i = 0; i < q.size(); i++) rv.push_back(q[i]);
return rv;
}
|
Grading
- Did you use a correct data structure? Deque, Queue or List was worth 6 points, Vector and Stack were worth three points. Set was worth two, and anything else zero.
- Was your solution O(n) in space? This was worth two points.
In other words, even if you used a
Deque, if you simply created it with push_front() and didn't
make sure that its maximum size was n, you didn't get these two points.
- Did you set up a return value of the correct type and return it? One point.
- Did you create the return value correctly? One point.
Question 2 - Basic Data Structures and Big-O - 12 Points
- A: Finding an item in a AVL tree with n items: O(log(n))
- B: Erasing the first item from a linked list with n items: Linked lists work in constant time: O(1)
- C: Performing a rotation on a node in an AVL tree with n items: Rotations manipulate a constant
number of pointers: O(1)
- D: Deleting an item from an AVL tree with n items. O(log(n))
- E: Finding an item in a regular binary search tree with n items. The search tree can be a search line: O(n)
- F: Erasing the first item from a deque with n items. Deques do this in constant time: O(1)
- G: Deleting an item from a set with n items. Sets and maps are just like AVL trees: O(log n)
- H: Finding an item that is in a hash table with n items that had no collisions when the items were inserted.
If there were no collisions, then every key is at its hash value in the hash table. Therefore, it will take constant time to
find it: O(1)
- I: Calling Push() on a stack with n items. Again, O(1) -- see the answer to Question 5.
- J: Inserting an item into a map with n items. O(log(n))
- K: Erasing the first item from a vector with n items. Vectors don't support this in constant time: O(n)
- L: Finding an item in a linked list with n items. To find an item in a linked list, you have to traverse the
list from the front: O(n)
Grading: 1 point per question. In your grade files, I used the following abbreviations:
- "1" = O(1)
- "l" = O(log(n))
- "n" = O(n)
- "nl" = O(n(log(n))
- "2" = O(n2)
- "!" = O(n!)
Question 3 - Were you in this class? - 10 Points
Straight from the lecture notes:
void Solve(Towers *t, int from, int to, int npieces)
{
int i, other;
if (npieces == 1) {
t->Make_Move(from, to);
return;
}
for (i = 0; i < 3; i++) if (i != from && i != to) other = i;
Solve(t, from, other, npieces-1);
t->Make_Move(from, to);
Solve(t, other, to, npieces-1);
}
|
Grading was subjective here. I gave you some credit if you at least gave me a base
case and some recursion, but not much if it wasn't too cogent.
Question 4 - Binary search trees 10 points
I quote from the lecture notes:
Case 1: The node has no children (it's a leaf node). You can simply
delete it.
Case 2: The node has just one child. To delete the node, replace it
with that child.
Case 3: The node has two children. In this case, you find the node
in the tree whose value is the greatest value less than (or equal to) the node's
value. That will be the rightmost node in the subtree rooted by the left child.
That node will not have a right child. First, delete it. Then use it to replace
the node that you are deleting.
Grading
- Case 1: 3 points
- Case 2: 3 points
- Case 3: 4 points
Question 5 - Stack em up - 10 points
Again, straight from the lecture notes:
void Stack::Push(string s)
{
Stacknode *newnode;
newnode = new Stacknode;
newnode->s = s;
newnode->next = top;
top = newnode;
}
string Stack::Pop()
{
string rv;
Stacknode *oldtop;
if (top == NULL) {
cerr << "Error: pop() called on an empty stack\n";
exit(1);
}
oldtop = top;
top = oldtop->next;
rv = oldtop->s;
delete oldtop;
return rv;
}
|
Grading
Five points for each method.
Question 6 - Traversals - 12 Points
- Tree 1: Preorder: J D H F T P L K N R V X -- k
- Tree 1: Postorder: F H D K N L R P X V T J -- g
- Tree 2: Preorder: J F D H R L K P N V T X -- m
- Tree 2: Postorder: D H F K N P L T X V F J -- d
Grading
Three points per traversal.
Question 7 - Traversals - 12 points
Tree 1: When you insert N, you get the left tree below. That is imbalanced at node J, and it's
a Zig-Zag, so you must perform a double-rotation about node L to get the right tree.
The answer is I.
Tree 2: When you delete M, you replace it with L. That tree is fine, so the
answer is J.
Tree 3: When you insert X, you get the left tree below. That is imbalanced at node T, and it's
a Zig-Zig, so you must perform a rotation about node V to get the right tree.
The answer is L.
Tree 4: When you delete G, you get the left tree below. That is imbalanced at node J, and it's
a Zig-Zag, so you must perform a double rotation about node P to get the right tree.
The answer is F.
Tree 5: When you delete W, you get the left tree below. That is imbalanced at node V, and it's
a Zig-Zig, so you must perform a single rotation about node R to get the right tree.
The answer is L.
Tree 6: When you delete B, you get an imbalance about D, which you fix
by a double-rotation about G. That is pictured to the left. That is imbalanced at node J, and it's
a Zig-Zag, so you must perform a double rotation about node P to get the right tree.
The answer is F.

Section 1.2 Sept. 24: Transposes and Permutations
Subsection 1.2.1 Exploring Symmetry
As usual, we should set up our working environment. There should be no output.
Exploration 1.2.1.
Create two symmetric matrices (probably of different sizes, just to be safe). Use the.inverse()
command to find their inverses. What do you notice? What do you wonder? Exploration 1.2.2.
Create a matrix \(A\text{.}\) Use the.transpose()
command and multiply \(A A^T\) and \(A^T A\text{.}\) What do you notice? What do you wonder? An advantage of working with symmetric matrices is in the elimination process. We really only need to work with half of the matrix (plus the main diagonal)! So let's see how symmetric matrices carry through to the \(LDU\) factorization.
Exploration 1.2.3.
Consider the matrix \(B\) below.- Confirm that \(B\) is symmetric by using the
.is_symmetric()
command. - Capture the matrices \(P\text{,}\) \(L\text{,}\) and \(U\text{,}\) using
P, L, U = B.LU(pivot='nonzero')
. Confirm that no row swaps were needed. - What do you notice? Choose a different symmetric matrix to see if the same behavior persists.
Exploration 1.2.4.
Strang writes \(PA = LU\text{,}\) but Sage calculates the \(P\) that satisfies \(A = PLU\text{.}\) Let's explore their relationship (though maybe you know what it is already?).- Given the \(A\) below, use
P, L, U = A.LU()
to calculate an \(LU\) decomposition. - Confirm that \(A = PLU\text{.}\)
- What permutation matrix \(P'\) satisfies \(P' A = LU\text{?}\) Confirm it in Sage.
Exercises <IP_ADDRESS> Exercises
1.
Find an example of a matrix \(A\) such that \(A^T A = 0\text{,}\) but \(A \neq 0\text{.}\)2.
These are true or false questions. If the statement is true, explain why you know it is true. If the statement is false, give an example that shows it is false.- The block matrix \(\left( \begin{smallmatrix} A & 0 \\ 0 & A \end{smallmatrix}\right)\) is automatically symmetric.
- If \(A\) and \(B\) are symmetric, then their product \(AB\) is symmetric.
- If \(A\) is not symmetric, then \(A^{-1}\) is not symmetric.
3.
For each of the following, find an example of a \(2\times 2\) symmetric matrix with the given property:- \(A\) is not invertible.
- \(A\) is invertible but cannot be factored into \(LU\text{.}\)
- \(A\) can be factored into \(LDL^T\text{,}\) but not into \(LL^T\) because \(D\) has negative entries.
4.
This is a new factorization of \(A\) into triangular times symmetric:
Start with \(A = LDU\text{.}\) Then \(A = B S\text{,}\) where \(B = L\left(U^T\right)^{-1}\) and \(S = U^T D U\text{.}\)
Explain why this choice of \(B\) is lower triangular with \(1\)'s on the diagonal. Expain why \(S\) is symmetric.

A thunderstorm, also known as an electrical storm, lightning storm, or thundershower, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder. Thunderstorms occur in a type of cloud known as a cumulonimbus. They are usually accompanied by strong winds, heavy rain, and sometimes snow, sleet, hail, or, in contrast, no precipitation at all. Thunderstorms may line up in a series or become a rainband, known as a squall line. Strong or severe thunderstorms include some of the most dangerous weather phenomena, including large hail, strong winds, and tornadoes. Some of the most persistent severe thunderstorms, known as supercells, rotate as do cyclones. While most thunderstorms move with the mean wind flow through the layer of the troposphere that they occupy, vertical wind shear sometimes causes a deviation in their course at a right angle to the wind shear direction.
 Unplug all appliances before the storm hits to prevent power surges. Close blinds and shades.
Keep away from windows. Avoid using the phone. Telephone lines can conduct electricity. Stay away from faucets, sinks and bathtubs. If you are in or near water, go to land immediately and find the best shelter you can— preferably inside a building rather than a car. If you're in a car, keep the windows closed. Pull to the side of the road to wait until the heavy rain subsides. Keep away from trees that could fall on your car. If you are outside, find a location that is not likely to flood. Avoid tall structures, such as towers, trees, fences, telephone lines or power lines. Squat low to the ground and assume a tucked position. Place your hands on your knees with your head tucked between them. Try to touch as little of your body to the ground as possible. Do not lie flat on the ground, as your fully-extended body will provide a larger surface to conduct electricity.
Once lightning has struck a person or an object, the person or object does not carry a charge and cannot harm you. So don't be afraid to touch or assist a person who needs help. Administer first aid or CPR immediately. A lightning victim usually suffers burns in two places on the body—where the lightning entered and where it exited.


#include <nn_ops.h>
Performs a padding as a preprocess during a convolution.
Similar to FusedResizeAndPadConv2d, this op allows for an optimized implementation where the spatial padding transformation stage is fused with the im2col lookup, but in this case without the bilinear filtering required for resizing. Fusing the padding prevents the need to write out the intermediate results as whole tensors, reducing memory pressure, and we can get some latency gains by merging the transformation calculations. The data_format attribute for Conv2D isn't supported by this op, and 'NHWC' order is used instead. Internally this op uses a single per-graph scratch buffer, which means that it will block if multiple versions are being run in parallel. This is because this operator is primarily an optimization to minimize memory usage.
Arguments:
[batch, in_height, in_width, in_channels]
.input
.[filter_height, filter_width, in_channels, out_channels]
.input
. Must be in the same order as the dimension specified with format.Returns:
Output
